Exercise of Warrant.     (a) Manner of Exercise.     (i) Cash Exercise.  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)           A    Where:        X = The number of Warrant Shares to be issued to the Holder pursuant to this cashless exercise;
 - 3 -       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 reasonably determined in good faith by the   Company’s Board of Directors.         (b) 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. 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.    (c) 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).       (d)  Reservation of Shares.  During the Exercise Period, the Company shall reserve and keep   available out of its authorized but unissued Common Stock shares of Common Stock equal to 100% of the   number of Warrant Shares issuable upon the full exercise of this Warrant.  All Warrant Shares which are   so issuable shall, 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 shares of Common Stock to be less than the number of such shares required to be reserved
 - 4 -   hereunder for issuance upon exercise of this Warrant.       (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. In no event shall the Company   be required to issue scrip or pay cash in lieu of fractional interests.      3. Adjustments and Extraordinary Events.        (a)  Stock Dividends, Subdivisions, Reclassifications or Combinations.  If the Company, at   any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes a distribution or   distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in   shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock   issued by the Company upon exercise of this Warrant), (ii) subdivides outstanding shares of Common Stock   into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares   of Common Stock into a smaller number of shares, or (iv) issues by reclassification of shares of the   Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be   multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding   treasury shares, if any) outstanding immediately before such event and of which the denominator shall be   the number of shares of Common Stock outstanding immediately after such event, and the number of shares   issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise   Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall   become effective immediately after the record date for the determination of stockholders entitled to receive   such dividend or distribution and shall become effective immediately after the effective date in the case of   a subdivision, combination or re-classification.      (b) Reorganization, Reclassification, Merger, Consolidation or Disposition of Assets. If during   the Exercise Period (i) the Company shall reorganize its capital, reclassify its capital stock, consolidate or   merge with or into another corporation (where the Company is not the surviving corporation or where there   is a change in or distribution with respect to the Common Stock of the Company); (ii) any tender offer or   exchange offer (whether by the Company or another individual or entity) is completed pursuant to which   holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or   property; (iii) the Company shall sell, transfer or otherwise dispose all or substantially all of its property,   assets or business to another corporation and, pursuant to the terms of such reorganization, reclassification,   merger, consolidation, tender or exchange offer, or disposition of assets, shares of common stock of the   successor or acquiring corporation, or any cash, shares of stock or other securities or property of any nature   whatsoever (including warrants or other subscription or purchase rights) in addition to or in lieu of common   stock of the successor or acquiring corporation (“Other Property”), are to be received by or distributed to   the holders of Common Stock of the Company, then the Holder shall have the right thereafter to receive,   upon exercise of this Warrant, the number of shares of common stock of the successor or acquiring   corporation or of the Company, if it is the surviving corporation, and Other Property receivable upon or as   a result of such reorganization, reclassification, merger, consolidation, tender or exchange offer, or   disposition of assets by a Holder of the number of shares of Common Stock for which this Warrant is   exercisable immediately prior to such event. In case of any such reorganization, reclassification, merger,   tender or exchange offer, consolidation or disposition of assets (“Extraordinary Transaction”), the successor   or acquiring corporation (if other than the Company) shall expressly assume the due and punctual   observance and performance of each and every covenant and condition of this Warrant to be performed and   observed by the Company and all the obligations and liabilities hereunder, subject to such modifications as   may be deemed appropriate (as determined in good faith by resolution of the Board of Directors of the   Company) in order to provide for adjustments of Warrant Shares for which this Warrant is exercisable   which shall be as nearly equivalent as practicable to the adjustments provided for in this Section 3(b).  As
 - 5 -   soon as commercially practicable following the Extraordinary Transaction, the successor or acquiring   corporation (if other than the Company), shall deliver to Holder a new warrant in repacement of this Warrant   consistent with the provisions referenced in the immediately preceding sentence against receipt by such   successor or acquiring corporation of the original of this Warrant.  For purposes of this Section 3(b),   “common stock of the successor or acquiring corporation” shall include stock of such corporation of any   class which is not preferred as to dividends or assets over any other class of stock of such corporation and   which is not subject to redemption and shall also include any evidences of indebtedness, shares of stock or   other securities which are convertible into or exchangeable for any such stock, either immediately or upon   the arrival of a specified date or the happening of a specified event and any warrants or other rights to   subscribe for or purchase any such stock.  The foregoing provisions of this Section 3(b) shall similarly   apply to successive reorganizations, reclassifications, mergers, tender or exchange offers, consolidations or   disposition of assets.       (c) Adjustment of Exercise Price upon Issuance of Common Stock, Options, Convertible   Securities, Etc.       (1) If during any period while this Warrant is outstanding, the Company (A) issues or   sells any Common Stock, Convertible Securities, warrants, or Options or (B) directly or indirectly   effectively reduces the conversion, exercise or exchange price for any Convertible Securities or Options   which are currently outstanding, at or to an effective Per Share Selling Price (as defined below) which is   less than the then-current Exercise Price, then in each such case the Exercise Price in effect immediately   prior to such issue or sale date, as applicable, shall be automatically reduced effective concurrently with   such issue or sale to an amount determined by multiplying the Exercise Price then in effect by a fraction,   (x) the numerator of which shall be the sum of (1) the number of shares of Common Stock outstanding   immediately prior to such issue or sale, plus (2) the number of shares of Common Stock which the aggregate   consideration received by the Company for such additional shares would purchase at such Exercise Price,   and (y) the denominator of which shall be the number of shares of Common Stock of the Company   outstanding immediately after such issue or sale. Notwithstanding the foregoing, however, no adjustment   hereunder shall be made with respect to an Exempt Issuance, as defined below.       (2) For the purposes of the foregoing adjustment, in the case of the issuance of any   Convertible Securities or Options, the maximum number of shares of Common Stock issuable upon   exercise, exchange or conversion of such Convertible Securities or Options shall be deemed to be   outstanding at the initial conversion or exercise price applicable to such securities, provided that no further   adjustment shall be made upon the actual issuance of Common Stock upon exercise, exchange or   conversion of such Convertible Securities or Options, and provided further that to the extent such   Convertible Securities or Options expire or terminate unconverted or unexercised, then at such time the   Exercise Price shall be readjusted as if such portion of such Convertible Securities or Options had not been   issued. For purposes of this Section 2.4, if an event occurs that triggers more than one of the above   adjustment provisions, then only one adjustment shall be made and the calculation method which yields the   greatest downward adjustment in the Exercise Price shall be used. If shares are issued for a consideration   other than cash, the Per Share Selling Price shall be the fair value of such consideration as determined in   good faith by independent certified public accountants mutually acceptable to the Company and the Holder.   In the event the Company directly or indirectly effectively reduces the conversion, exercise or exchange   price for any Convertible Securities or Options which are currently outstanding, then the Per Share Selling   Price shall equal such effectively reduced conversion, exercise or exchange price.       (3) As used herein, “Exempt Issuance” means the issuance of (a) shares of Common   Stock or Options or Convertible Securities to employees, officers, consultants or directors of the Company   pursuant to any stock or option plan duly adopted for such purpose, by a majority of the non-employee   members of the Board of Directors or a majority of the members of a committee of non-employee directors
 - 6 -   established for such purpose, (b) Common Stock, Convertible Securities, warrants, or Options upon the   exercise or exchange of or conversion of any securities issued hereunder and/or other securities exercisable   or exchangeable for or convertible into shares of Common Stock issued and outstanding as of the date of   the Agreement, provided that such securities have not been amended since the date of the Agreement to   increase the number of such securities or to decrease the exercise price, exchange price or conversion price   of such securities; (c) shares of Common Stock issued by reason of a dividend, stock split, split-up or other   distribution on shares of Common Stock; (d) shares of Common Stock, Convertible Securities, warrants or   Options in connection with transactions with lenders or other commercial partners, the terms of which are   approved by the Board of Directors, in each case, the primary purpose of which is not to raise equity capital;   (e) shares of Common Stock, Convertible Securities, warrants or Options issued pursuant to mergers,   acquisitions, or asset sales approved by a majority of the disinterested directors of the Company, provided   that any such issuance shall provide to the Company additional benefits in addition to the investment of   funds, but shall not include a transaction in which the Company is issuing securities primarily for the   purpose of raising equity capital;  (f) shares of Common Stock, Convertible Securities, Warrants or Options   issued pursuant to the Agreement   and (g) shares of Common stock issued by the Company in connection   with a rights offering by the Company to its stockholders (including any standby or similar commitment   thereunder)  to be undertaken and completed within 150 days of the Issue Date.       (4) For purposes hereof: (i) “Convertible Securities” means any stock or securities   (other than Options) directly or indirectly convertible into or exercisable or exchangeable for Common   Stock; (ii) “Options” means any rights, warrants or options to subscribe for or purchase Common Stock or   Convertible Securities; and (iii) “Per Share Selling Price” shall include the amount actually paid by third   parties for each share of Common Stock in a sale or issuance by the Company. A sale of shares of Common   Stock shall include the sale or issuance of Convertible Securities or Options, and in such circumstances the   Per Share Selling Price of the Common Stock covered thereby shall also include the exercise, exchange or   conversion price thereof (in addition to the consideration received by the Company upon such sale or   issuance less the fee amount as provided above).      4. Restrictions on Transfer.        (a) Restricted Securities.  The Holder acknowledges that: (i) it has been advised by the   Company that this Warrant and the Warrant Shares issuable upon exercise thereof (collectively the   “Securities”) have not been registered under the Securities Act of 1933, as amended (the “Securities Act”)   and (ii) assuming the accuracy of the representations and warranties of the Holder contained  herein, this   Warrant has been issued and the Warrant Shares will be 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/or Regulation D   promulgated thereunder and exempt from state registration or qualification under applicable state laws. The   Holder acknowledges that he has been informed by the Company of, or is otherwise familiar with, the   nature of the limitations imposed by the Securities Act and the rules and regulations thereunder on the   transfer of securities. In particular, the Holder agrees that no sale, assignment or transfer of the Securities   shall be valid or effective, and the Company shall not be required to give any effect to any such sale,   assignment or transfer, unless (i) the sale, assignment or transfer of the Securities is registered under the   Securities Act, and the Company has no obligations or intention to so register the Securities except as may   otherwise be provided herein, or (ii) the Securities are sold, assigned or transferred in accordance with all   the requirements and limitations of Rule 144 under the Securities Act or such sale, assignment, or transfer   is otherwise exempt from registration under the Securities Act. 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 to a transferee that is not an   Affiliate of the Holder (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
 - 7 -   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. The Holder represents and warrants that he has acquired this Warrant and will acquire   the Securities 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 Act.       (b) Legends. The Holder understands that this Warrant and the Warrant Shares, as applicable,   shall bear a restrictive legend in substantially the form set forth below (and a stop-transfer order may be   placed against transfer of the certificates for such securities):        THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED   UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR   APPLICABLE STATE SECURITIES LAWS.  THE SECURITIES MAY NOT BE OFFERED FOR   SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE   REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT, OR (B) AN   OPINION OF COUNSEL, IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT   REQUIRED UNDER SAID ACT (II) UNLESS SOLD OR TRANSFERRED TO A “QUALIFIED   INSTITUTIONAL BUYER” WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES   ACT OR (III) UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT.         (c)   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 Purchase Agreement.         (d)       Disposition of Warrant or Warrant Shares.  With respect to any offer, sale or other   disposition of this Warrant or any shares of Common Stock acquired pursuant to the exercise of this Warrant   prior to registration of such Warrant or shares of Common Stock, 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 other disposition may be effected   without registration or qualification (under the Act as then in effect or any federal or state securities law   then in effect) of this Warrant or such shares of Common Stock and indicating whether or not under the Act   certificates for this Warrant or such shares of Common Stock 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 seven (7) days after receipt of the written notice, shall notify the Holder that   the Holder may sell or otherwise dispose of this Warrant or such 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 shares of Common   Stock issued upon exercise of this Warrant may be offered, sold or otherwise disposed of in accordance
 - 8 -   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 shares of Common Stock 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.       5. Exercise Limitation.  Without the approval of the Company’s stockholders, the Holder (together   with such Holder’s Affiliates, and any Persons acting as a group together with such Holder or any of such   Holder’s Affiliates) shall not have the right to exercise the Warrants to the extent that such exercise would   cause the Company to exceed the aggregate number of shares of Common Stock which the Company may   issue or be deemed to have issued without breaching the Company’s obligations under the applicable rules   and regulations of the Nasdaq Stock Market (including, without limitation, Nasdaq Listing Rule 5635(d))   and such other Trading Market on which the Company’s shares of Common Stock are then quoted or listed   for trading. As used herein, “Trading Market” means any of the following markets or exchanges on which   the Common Stock is listed or quoted for trading on the date in question: the NYSE AMEX, the Nasdaq   Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market, the New York Stock   Exchange or the OTC Bulletin Board.      6. Exchange and Replacement of Warrant Certificates.         (a) Exchanges. This Warrant Certificate is exchangeable without expense, upon the surrender   hereof by the registered Holder at the principal executive office of the Company, for a new Warrant   Certificate of like tenor and date representing in the aggregate the right to purchase the same number of   Warrant Shares in such denominations as shall be designated by the Holder thereof at the time of such   surrender.       (b) Loss, Destruction, Etc. Upon receipt by the Company of evidence reasonably satisfactory   to it of the loss, theft, destruction or mutilation of this Warrant Certificate, and, in case of loss, theft or   destruction, of indemnity or security reasonably satisfactory to it, and reimbursement to the Company of   all reasonable expenses incidental thereto, and upon surrender and cancellation of the Warrants, if   mutilated, the Company will make and deliver a new Warrant of like tenor, in lieu thereof and any such   lost, stolen, destroyed or mutilated warrant shall thereupon become void.      7. No Rights as 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 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.
 - 9 -   8. Notices; Adjustments.     (a)   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.    (b) Upon the occurrence of any adjustments pursuant to Section 3 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(b) 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. Failure to give such notice, or any defect therein, shall not, however, affect the legality or   validity of any such action.   9. Miscellaneous.         (a) Successors and Assigns.
