COMMON STOCK PURCHASE WARRANT

To Purchase 750,000 Shares of Common Stock of

EXABYTE CORPORATION

THIS COMMON STOCK PURCHASE WARRANT (the “Warrant”) CERTIFIES that, for value received, IMATION CORP. or its transferee (the “Holder”), is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after the date of original issuance of this Warrant (the “Initial Exercise Date”) and on or prior to the fifth anniversary of the Initial Exercise Date (the “Termination Date”) but not thereafter, to subscribe for and purchase from Exabyte Corporation, a Delaware corporation (the “Company”), up to 750,000 shares (the “Warrant Shares”) of Common Stock, par value $0.001 per share, of the Company (the “Common Stock”). The purchase price of one share of Common Stock (the “Exercise Price”) under this Warrant shall be $2.80, subject to adjustment hereunder. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Agreement for Issuance of Stock (the “Issuance Agreement”), dated October 31, 2005, by and between Imation Corp. and the Company.

1. Title to Warrant. Prior to the Termination Date and subject to compliance with applicable laws and Section 7 of this Warrant, this Warrant and all rights hereunder are transferable, in whole or in part, at the office or agency of the Company by the Holder in person or by duly authorized attorney, upon surrender of this Warrant together with the Assignment Form annexed hereto properly endorsed. The transferee shall sign an investment letter in form and substance reasonably satisfactory to the Company.

2. Authorization of Shares. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant, be duly authorized, validly issued, fully paid and non-assessable and free from all taxes, liens and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

Exercise of Warrant.

(a) Exercise of the purchase rights represented by this Warrant may be made at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of such Holder appearing on the books of the Company) of a duly executed facsimile copy of the Notice of Exercise Form annexed hereto; provided, however, within three Trading Days of the date said Notice of Exercise is delivered to the Company, the Holder shall have surrendered this Warrant to the Company and the Company shall have received payment of the aggregate Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn on a United States bank. Certificates for shares purchased hereunder shall be delivered to the Holder within three Trading Days after the exercise date determined in accordance with the following sentence (“Warrant Share Delivery Date”). This Warrant shall be deemed to have been exercised on the later of the date the Notice of Exercise is delivered to the Company and the date the Exercise Price is received by the Company. The Company shall, if available, deliver any certificate or certificates for Warrant Shares required to be delivered upon exercise of this Warrant electronically through the Depository Trust Corporation or another established clearing corporation performing similar functions, and the Company shall be deemed to have satisfied its delivery obligations if Warrant Shares are made available through such clearing agent on or prior to the Warrant Share Delivery Date. The Warrant Shares shall be deemed to have been issued, and the 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 the Warrant has been exercised by payment to the Company of the Exercise Price and all taxes required to be paid by the Holder, if any, pursuant to Section 5 prior to the issuance of such shares, have been paid. If the Company fails to deliver to the Holder a certificate or certificates representing the Warrant Shares pursuant to this Section 3(a) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise. In addition to any other rights available to the Holder, if the Company fails to deliver to the Holder a certificate or certificates representing the Warrant Shares by the Warrant Share Delivery Date, and if after such day the Holder is

required by its broker to purchase (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (1) pay in cash to the Holder the amount by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of Warrant Shares equal to the number of shares that the Holder was obligated to purchase times (B) the price at which the sell order giving rise to such purchase obligation was executed (including brokerage commissions, if any), 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 shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. 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 a 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 shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

(b) If this Warrant shall have been exercised in part, the Company shall, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver to Holder a new Warrant evidencing the rights of Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

(c) If at any time after one year from the Initial Exercise Date there is no effective S-1 Registration Statement registering the resale of the Warrant Shares by the Holder, during any such periods this Warrant may also be exercised by means of a “cashless exercise” in which the Holder shall be entitled to receive a certificate for the number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) = the VWAP (as defined below) on the business day immediately preceding the date of such election during which the Trading Market (as defined below) shall be open for business;

(B) = the Exercise Price of this Warrant, as adjusted; and

(X) = the number of Warrant Shares issuable upon exercise of this Warrant in accordance with the terms of this Warrant by means of a cash exercise rather than a cashless exercise.

Except for the above method of calculating the number of shares to be issued, the procedures for a cashless exercise shall be the same as for a cash exercise pursuant to the other provisions of this Section 3.

For purposes of this Warrant, “VWAP” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on the American Stock Exchange, the New York Stock Exchange, the Nasdaq National Market, the Nasdaq SmallCap Market or the OTC Bulletin Board (each a “Trading Market”), the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the primary Trading Market as reported by Bloomberg Financial L.P. (based on a Trading Day from 9:30 a.m. EST to 4:02 p.m. Eastern Time) using the VAP function; (b) if the Common Stock is not then listed or quoted on the Trading Market and if prices for the Common Stock are then reported in the “Pink Sheets” published by the National Quotation Bureau Incorporated (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported; or (c) in all other cases, the fair market value of a share of Common Stock as determined by a nationally recognized-independent appraiser selected in good faith by ▇▇▇▇▇▇.

4. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which Holder would otherwise be entitled to purchase upon such exercise, the Company shall pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price.

5. Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event certificates for Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder; and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto.

6. Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

Transfer, Division and Combination.

(a) Subject to compliance with any applicable securities laws and the conditions set forth in Sections 1 and 7(e) hereof and to the provision of Section 5.2 of the Issuance Agreement, this Warrant and all rights hereunder are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer

taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. A Warrant, if properly assigned, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

(b) This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 7(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice.

(c) The Company shall prepare, issue and deliver at its own expense (other than transfer taxes) the new Warrant or Warrants under this Section 7.

(d) The Company agrees to maintain, at its aforesaid office, books for the registration and the registration of transfer of the Warrants.

(e) 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)(1), (a)(2), (a)(3), (a)(7), or (a)(8) promulgated under the Securities Act or a qualified institutional buyer as defined in Rule 144A(a) under the Securities Act.

8. No Rights as Shareholder until Exercise. This Warrant does not entitle the Holder to any voting rights or other rights as a shareholder of the Company prior to the exercise hereof. Upon the surrender of this Warrant and the payment of the aggregate Exercise Price (or by means of a cashless exercise), the Warrant Shares so purchased shall be and be deemed to be issued to such Holder as the record owner of such shares as of the close of business on the later of the date of such surrender or payment.

9. Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case

of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

10. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall be a Saturday, Sunday or a legal holiday, then such action may be taken or such right may be exercised on the next succeeding day not a Saturday, Sunday or legal holiday.

11.

Adjustments of Exercise Price and Number of Warrant Shares.

(a) Reset Provision. On the 30-day anniversary of the Initial Exercise Date, the Exercise Price shall be reset to equal the average of the daily VWAPs for the immediately preceding five Trading Days if such average is less than $2.80 (subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions affecting the number of outstanding shares of the Common Stock that occur after the Initial Exercise Date); provided, however, that the adjusted Exercise Price determined pursuant to this Section 11(a) shall not be less than $1.80 (subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions affecting the number of outstanding shares of the Common Stock that occur after the Initial Exercise Date).

(b) Stock Splits, etc. The number and kind of securities purchasable upon the exercise of this Warrant and the Exercise Price shall be subject to adjustment from time to time upon the happening of any of the following. In case the Company shall, after the Initial Exercise Date, (i) pay a dividend in shares of Common Stock or make a distribution in shares of Common Stock to holders of its outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares, (iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, or (iv) issue any shares of its capital stock in a reclassification of the Common Stock, then the number of Warrant Shares purchasable upon exercise of this Warrant immediately prior thereto shall be adjusted so that the Holder shall be entitled to receive the kind and number of Warrant Shares or other securities of the Company which it would have owned or have been entitled to receive had such Warrant been exercised in advance thereof. Upon each such adjustment of the kind and number of Warrant Shares or other securities of the Company which are purchasable hereunder, the Holder shall thereafter be entitled to purchase the number of Warrant Shares or other securities resulting from such adjustment at an Exercise Price per Warrant Share or other security obtained by multiplying the Exercise Price in effect immediately prior to such adjustment by the number of Warrant Shares purchasable pursuant hereto immediately prior to such adjustment and dividing such product by the number of Warrant Shares or other securities of the Company that are purchasable pursuant hereto immediately after such adjustment. An adjustment made pursuant to this Section 11(b) shall become effective immediately after the effective date of such event retroactive to the record date, if any, for such event.

(c) Anti-Dilution Provisions. During the Exercise Period, the Exercise Price shall be subject to adjustment from time to time as provided in this Section 11(c).

(i) Adjustment of Exercise Price. If and whenever the Company issues or sells, or in accordance with Section 11(c)(ii) hereof is deemed to have issued or sold, any shares of Common Stock, other than pursuant to an Exempt Issuance (as defined below) or a transaction described in Section 11(b) above, for an effective consideration per share of less than the Exercise Price then in effect (such lower price, the “Base Share Price”) (each such issuance, a “Dilutive Issuance”), then, (a) from the Initial Exercise Date until the 18-month anniversary of the Effective Date, the Exercise Price shall be reduced to a price equal to the Base Share Price and (b) after the 18-month anniversary of the Effective Date, the Exercise Price shall be reduced by multiplying the Exercise Price by a fraction, the numerator of which is the number of shares of Common Stock issued and outstanding immediately prior to the Dilutive Issuance plus the number of shares of Common Stock which the aggregate consideration received or receivable by the Company in connection with such Dilutive Issuance would purchase at the then effective Exercise Price, and the denominator of which shall be the sum of the number of shares of Common Stock issued and outstanding immediately prior to the Dilutive Issuance plus the number of shares of Common Stock so issued or issuable in connection with the Dilutive Issuance. Such adjustment shall be made upon the issuance of any shares of Common Stock or any securities of the Company or its subsidiaries which would entitle the holder thereof to receive at any time Common Stock, including without limitation, any convertible debt or preferred stock, or other instrument that is at any time convertible into or exchangeable for Common Stock but excluding Options as defined below (“Common Stock Equivalents”).

(ii) Effect on Exercise Price of Certain Events. For purposes of determining the adjusted Exercise Price under Section 11(c)(i) hereof, the following will be applicable:

(A) Issuance of Rights or Options. If the Company in any manner issues or grants any warrants, rights or options, whether or not immediately exercisable, to subscribe for or to purchase Common Stock or Common Stock Equivalents (such warrants, rights and options to purchase Common Stock or Common Stock Equivalents are hereinafter referred to as “Options”) and the effective price per share for which Common Stock is issuable upon the exercise of such Options is less than the then effective Exercise Price (“Below Base Price Options”), then the maximum total number of shares of Common Stock issuable upon the exercise of all such Below Base Price Options (assuming full exercise, conversion or exchange of Common Stock Equivalents, if applicable) will, as of the date of the issuance or grant of such Below Base Price Options, be deemed to be outstanding and to have been issued and sold by the Company for such effective price per share and the maximum consideration payable to the Company upon such exercise (assuming full exercise, conversion or exchange of Common Stock Equivalents, if applicable) will be deemed to

have been received by the Company. For purposes of the preceding sentence, the “effective price per share for which Common Stock is issuable upon the exercise of such Below Base Price Options” is determined by dividing (i) the total amount, if any, received or receivable by the Company as consideration for the issuance or granting of all such Below Base Price Options, plus the minimum aggregate amount of additional consideration, if any, payable to the Company upon the exercise of all such Below Base Price Options, plus, in the case of Common Stock Equivalents issuable upon the exercise of such Below Base Price Options, the minimum aggregate amount of additional consideration payable upon the exercise, conversion or exchange thereof at the time such Common Stock Equivalents first become exercisable, convertible or exchangeable, by (ii) the maximum total number of shares of Common Stock issuable upon the exercise of all such Below Base Price Options (assuming full conversion of Common Stock Equivalents, if applicable). No further adjustment to the Exercise Price will be made upon the actual issuance of such Common Stock upon the exercise of such Below Base Price Options or upon the exercise, conversion or exchange of Common Stock Equivalents issuable upon exercise of such Below Base Price Options.

(B) Issuance of Common Stock Equivalents. If the Company in any manner issues or sells any Common Stock Equivalents, whether or not immediately convertible (other than where the same are issuable upon the exercise of Options) and the effective price per share for which Common Stock is issuable upon such exercise, conversion or exchange is less than the then effective Exercise Price, then the maximum total number of shares of Common Stock issuable upon the exercise, conversion or exchange of all such Common Stock Equivalents will, as of the date of the issuance of such Common Stock Equivalents, be deemed to be outstanding and to have been issued and sold by the Company for such effective price per share and the maximum consideration payable to the Company upon such exercise (assuming full exercise, conversion or exchange of Common Stock Equivalents, if applicable) will be deemed to have been received by the Company. For the purposes of the preceding sentence, the “effective price per share for which Common Stock is issuable upon such exercise, conversion or exchange” is determined by dividing (i) the total amount, if any, received or receivable by the Company as consideration for the issuance or sale of all such Common Stock Equivalents, plus the minimum aggregate amount of additional consideration, if any, payable to the Company upon the exercise, conversion or exchange thereof at the time such Common Stock Equivalents first become exercisable, convertible or exchangeable, by (ii) the maximum total number of shares of Common Stock issuable upon the exercise, conversion or exchange of all such Common Stock Equivalents. No further adjustment to the Exercise Price will be made upon the actual

issuance of such Common Stock upon exercise, conversion or exchange of such Common Stock Equivalents.

(C) Change in Option Price or Conversion Rate. If there is a change at any time in (i) the amount of additional consideration payable to the Company upon the exercise of any Options; (ii) the amount of additional consideration, if any, payable to the Company upon the exercise, conversion or exchange of any Common Stock Equivalents; or (iii) the rate at which any Common Stock Equivalents are convertible into or exchangeable for Common Stock (in each such case, other than under or by reason of provisions designed to protect against dilution), the Exercise Price in effect at the time of such change will be readjusted, upon ten Trading Days’ prior notice to the Holder, to the Exercise Price which would have been in effect at such time had such Options or Common Stock Equivalents still outstanding provided for such changed additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold. To the extent any Options or Common Stock Equivalents expire without exercise in full, the Exercise Price shall be recomputed to reflect only the number of shares actually issued upon the exercise or conversion of the Options and Common Stock Equivalents and the Exercise Price in effect at the time of such change will be readjusted to the Exercise Price which would have been in effect at such time had only such Options or Common Stock Equivalents so converted or exercised been initially granted, issued or sold; provided, however, any such adjustment shall only be effective upon ten Trading Days’ prior notice to the Holder.

(D) Calculation of Consideration Received. If any Common Stock, Options or Common Stock Equivalents are issued, granted or sold for cash, the consideration received therefor for purposes of this Warrant will be the amount received by the Company therefor, before deduction of reasonable commissions, underwriting discounts or allowances or other reasonable expenses paid or incurred by the Company in connection with such issuance, grant or sale. In case any Common Stock, Options or Common Stock Equivalents are issued or sold for a consideration part or all of which shall be other than cash, the amount of the consideration other than cash received by the Company will be the fair market value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company will be the fair market value (closing price, if traded on any Trading Market) thereof as of the date of receipt. In case any Common Stock, Options or Common Stock Equivalents are issued in connection with any merger or consolidation in which the Company is the surviving corporation, the amount of consideration therefor will be deemed to be the fair market value of such portion of the net assets and business of the non-surviving corporation as is attributable to such Common Stock, Options or

Common Stock Equivalents, as the case may be. The fair market value of any consideration other than cash or securities will be determined in good faith by the Company’s Board of Directors or, in the case of an issuance of more than 1,000,000 shares, by an investment banker or other appropriate expert selected by the Company and reasonably acceptable to Holder, with the costs of such appraisal to be borne by the Company.

(E) Exceptions to Adjustment of Exercise Price. Notwithstanding the foregoing, no adjustment will be made under this Section 11(c) in respect of an Exempt Issuance. For purposes of this Agreement, “Exempt Issuance” shall mean the issuance of (a) shares of Common Stock or options to employees, officers or directors of the Company pursuant to any stock or option plan duly adopted by a majority of the non-employee members of the Board of Directors of the Company or a majority of the members of a committee composed exclusively of non-employee directors established for such purpose or otherwise issued in connection with employment, (b) securities upon the conversion or exercise of any Notes or Series AA Convertible Preferred Stock (“Preferred Stock”), any warrants issued to the original holders of the Company’s 10% Secured Convertible Subordinated Notes issued pursuant to the Securities Purchase Agreement (the “Purchase Agreement”), dated October 31, 2005, among the Company and the purchasers that are a party thereto (the “Notes”) or the holders of the Preferred Stock or any other convertible securities, options or warrants issued and outstanding on the date of this Agreement, provided that such securities have not been amended since the date of this Agreement to increase the number of shares of Common Stock issuable pursuant to such securities (but if the number is increased, this proviso will only apply to the increased number, not the number outstanding on the date of this Agreement), (c) securities issued pursuant to equipment financing, leasing arrangements, commercial bank financings, corporate partnering arrangements, strategic transactions (including joint ventures), acquisitions, mergers or technology transfer or development arrangements, provided any such issuance shall not include a transaction in which the Company is issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities, (d) as a dividend or distribution on, or reclassification of, other outstanding shares for which an adjustment to the Conversion Price (as defined in the Purchase Agreement) is made pursuant to Section 5(e)(ii) of the Notes issued pursuant to the Purchase Agreement, (e) shares of Common Stock or options to consultants or suppliers, provided the number of shares of Common Stock or shares underlying options does not exceed, in the aggregate, 0.5 % of the outstanding Common Stock in any 12-month period.

(iii) Minimum Adjustment of Exercise Price. No adjustment of the Exercise Price shall be made in an amount of less than $0.01, subject to

adjustment for reverse and forward stock splits and the like, and any such lesser adjustment shall be carried forward and shall be made at the time and together with the next subsequent adjustment which, together with any adjustments so carried forward, shall amount to not less than $0.01, subject to adjustment for reverse and forward stock splits and the like. For purposes of this Section 11(c), the number of shares of Common Stock deemed to be “issued and outstanding” as of a given time shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding at such time plus the number of shares of Common Stock issuable upon conversion of the Company’s Preferred Stock and the Notes at such time.

12. Reorganization, Reclassification, Merger, Consolidation or Disposition of Assets. In case the Company shall reorganize its capital, reclassify its capital stock, consolidate or merge with or into another entity (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), or sell, transfer or otherwise dispose of its property, assets or business to another entity and, pursuant to the terms of such reorganization, reclassification, merger, consolidation or disposition of assets, shares of common stock of the successor or acquiring entity, 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 entity (“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 entity 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 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, consolidation or disposition of assets, the successor or acquiring entity (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 12. For purposes of this Section 12, “common stock of the successor or acquiring entity” shall include equity of such entity of any class which is not preferred as to dividends or assets over any other class of equity of such entity 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 equity, 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 equity. The foregoing provisions of this Section 12 shall similarly apply to successive reorganizations, reclassifications, mergers, consolidations or disposition of assets.

13. Voluntary Adjustment by the Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

14. Notice of Adjustment. Whenever the number of Warrant Shares or number or kind of securities or other property purchasable upon the exercise of this Warrant or the Exercise Price is adjusted, as herein provided, the Company shall give notice thereof to the Holder, which notice shall state the number of Warrant Shares (and other securities or property) purchasable upon the exercise of this Warrant and the Exercise Price of such Warrant Shares (and other securities or property) after such adjustment, setting forth a brief statement of the facts requiring such adjustment and setting forth the computation by which such adjustment was made.

15.

Notice of Corporate Action. If at any time:

(a) the Company shall take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or other distribution, or any right to subscribe for or purchase any evidences of its indebtedness, any shares of stock of any class or any other securities or property, or to receive any other right, or

(b) there shall be any capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company or any consolidation or merger of the Company with, or any sale, transfer or other disposition of all or substantially all the property, assets or business of the Company to, another corporation or,

then, in any one or more of such cases, the Company shall give to Holder (i) at least 20 days’ prior written notice of the date on which a record date shall be selected for such dividend, distribution or right or for determining rights to vote in respect of any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, liquidation or winding up, and (ii) in the case of any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up, at least 20 days’ prior written notice of the date when the same shall take place. Such notice in accordance with the foregoing clause also shall specify (i) the date on which any such record is to be taken for the purpose of such dividend, distribution or right, the date on which the holders of Common Stock shall be entitled to any such dividend, distribution or right, and the amount and character thereof, and (ii) the date on which any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up is to take place and the time, if any such time is to be fixed, as of which the holders of Common Stock shall be entitled to exchange their Warrant Shares for securities or other property deliverable upon such disposition, dissolution, liquidation or winding up. Each such written notice shall be delivered in accordance with Section 18(d).

16. Authorized Shares. The Company covenants that during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the Warrant Shares upon the

exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be listed.

Except and to the extent as waived or consented to by the (i) Holder or, (ii) if this Warrant has been assigned to more than one Holder or divided in accordance with Sections 7(a) or 7(b) hereof, respectively, then by the Holders of a majority of the Warrants then outstanding, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (a) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (b) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant, and (c) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be necessary to enable the Company to perform its obligations under this Warrant.

Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall exercise commercially reasonable efforts to obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

17. Registration Under Securities Act of 1933, as amended. The Company agrees that the Warrant Shares shall have certain registration rights pursuant to and as set forth in the Issuance Agreement. The provisions set forth in the Issuance Agreement or similar agreement relating to the above in effect as of the date hereof may not be amended, modified or waived without the prior written consent of Holder.

18.

Miscellaneous.

(a) Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance with the laws of the state of Delaware without giving effect to any choice of law rule that would cause the application of the laws of any jurisdiction other than the state of Delaware to the rights and duties of the parties.

(b) Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, will have restrictions upon resale imposed by state and federal securities laws.

(c) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice Holder’s rights, powers or remedies, notwithstanding all rights hereunder terminate on the Termination Date. If the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

(d) Notices. All notices, requests, consents and other communications under this Agreement shall be in writing, shall be mailed by first-class registered or certified airmail, confirmed facsimile or nationally recognized overnight express courier postage prepaid, and shall be delivered as addressed as follows:

(e) Limitation of Liability. No provision hereof, in the absence of any affirmative action by Holder to exercise this Warrant or purchase Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

(f) Remedies. Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate.

(g) Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors of the Company and the successors and permitted assigns of Holder.

(h) Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the holders of a majority of the Warrants issued pursuant to the Issuance Agreement that remain outstanding.

(i) Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

(j) Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.
