WARRANT CERTIFICATE

To Purchase Shares of Common Stock of

OCLARO, INC.

No. W- Warrants

THIS CERTIFIES THAT, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged,             , located at             , Attention:              or its registered assigns (the “Holder”), is the registered owner of the number of warrants specified above (collectively, the “Warrants”), each of which warrants entitles the holder, subject to the adjustment provisions and the conditions and limitations hereinafter set forth, to purchase from Oclaro, Inc. (together with its successor and assignee, the “Company”), a corporation organized and existing under the laws of the State of Delaware, one share, as adjusted pursuant to Section 4 hereof, of the Company’s Common Stock at a purchase price equal to $1.50 per share, as adjusted pursuant to Section 4 hereof, (the “Exercise Price”). The Warrants shall not be terminable by the Company prior to the Expiration Date (as defined in Section 10 hereof). The shares of Common Stock issuable upon exercise of the Warrants (and any other or additional shares, securities or property that may hereafter be issuable upon exercise of the Warrants) are sometimes referred to herein as the “Warrant Shares,” and the maximum number of shares so issuable under this Warrant Certificate is sometimes referred to as the “Aggregate Number” (as such number may be increased or decreased, as more fully set forth herein).

The Warrants shall be void and all rights represented hereby shall cease after 5:00 p.m. Eastern Time on the Expiration Date.

The Warrants are part of an authorized issue of warrants (the “Authorized Warrants”) issued on the date hereof pursuant to the terms of the Credit Agreement and initially exercisable for an aggregate of 1,836,000 shares of Common Stock.

Certain terms used in this Warrant Certificate are defined in Section 10 hereof.

The Warrants are subject to the following provisions, terms and conditions:

1. Exercise; Issue of Certificates; Payment for Shares. (a) The Warrants represented by this Warrant Certificate may be exercised by the Holder, in whole or in part (but not as to fractional shares of Common Stock), to purchase the Aggregate Number of shares (initially equal to shares) of Common Stock at all times after 5:00 p.m. Eastern Time on May 6, 2013 and on or prior to 5:00 p.m. Eastern Time on the Expiration Date hereof.

(b) The Warrants shall be exercisable in whole at any time or in part from time to time by surrendering this Warrant Certificate on any Business Day (with the Exercise Form annexed hereto as Schedule 1 properly completed and executed) to the Company at its principal office specified in Section 15, or its then current address, and upon payment to the Company of the Exercise Price for the Warrant Shares being purchased.

(c) Payment of the aggregate Exercise Price with respect to an exercise in whole or in part of any Warrants may be made, in the sole discretion of the Holder, in the form of any of the following: (a) by cash or a check or bank draft in New York Clearing House funds, (b) by the surrender of the applicable Warrant or Warrants, and without the payment of the Exercise Price in cash, for such number of Warrant Shares equal to the product of (1) the number of Warrant Shares for which such Warrant or Warrants are exercisable with payment in cash of the Exercise Price as of the date of exercise and (2) the Cashless Exercise Ratio, (c) by tendering Term Loans having an aggregate principal amount, plus accrued and unpaid interest, if any, thereon to the date of exercise, equal to the Exercise Price or (d) by any combination of (a), (b) and (c) above. Such certificate or certificates shall be deemed to have been issued and any Person so designated to be named therein shall be deemed for all purposes to have become a holder of record of such Warrant Shares as of the close of business on the Business Day of the surrender of this Warrant Certificate and payment of the Exercise Price as aforesaid.

(d) Certificates for the shares so purchased shall be delivered to the Holder within a reasonable time, not exceeding five (5) days, after this Warrant Certificate shall have been so exercised, and unless the Warrants represented by this Warrant Certificate have expired or been fully exercised, a new Warrant Certificate representing the number of shares with respect to which this Warrant Certificate shall not then have been exercised shall also be delivered to the Holder within such time.

-2-

2. Shares to be Fully Paid; Reservation of Shares; Listing. The Company covenants and agrees that: (a) all Warrant Shares will, upon issuance, be original-issue shares (and not treasury stock) fully paid and nonassessable and free from all taxes, claims, liens, charges and other encumbrances with respect to the issue thereof; (b) without limiting the generality of the foregoing, it will from time to time take all such action as may be required to assure that the par value per share of Common Stock shall at all times be less than or equal to the Exercise Price; (c) during the period within which the Warrants represented by this Warrant Certificate may be exercised, the Company will at all times have authorized and reserved for the purpose of issue or transfer upon exercise of the Warrants represented by this Warrant Certificate a sufficient number of original-issue shares of its Common Stock to provide for the exercise of all the Warrants represented by this Warrant Certificate; and (d) upon the exercise of the Warrants represented by this Warrant Certificate, it will, at its expense, promptly notify each securities exchange on which any Common Stock is at the time listed of such issuance, and use its best efforts to maintain a listing of all shares of Common Stock from time to time issuable upon the exercise of the Warrants represented by this Warrant Certificate to the extent such shares can be listed.

3. Registration Rights. The Holder shall be entitled to all of the benefits, and subject to all of the obligations, of the Registration Rights Agreement, in connection with the Warrants and the Warrant Shares, if issued.

4. Adjustments to Exercise Price and Aggregate Number. The Exercise Price and the Aggregate Number of shares of Common Stock issuable upon the exercise of each Warrant (the “Exercise Rate”) is subject to adjustment from time to time upon the occurrence of the events enumerated in this Section 4.

(a) Adjustment for Change in Capital Stock. If the Company:

(1) pays a dividend or makes any other distribution on its Common Stock in shares of its Common Stock or other capital stock of the Company; or

(2) subdivides, combines or reclassifies its outstanding shares of Common Stock,

then, in each case, the Exercise Rate and the Exercise Price in effect immediately prior to such action shall be proportionately adjusted so that the Holder may upon payment of the same aggregate Exercise Price payable immediately prior to such action receive the Aggregate Number and kind of shares of capital stock of the Company which the Holder would have owned immediately following such action if such Warrants had been exercised immediately prior to such action.

Any such adjustment shall become effective immediately after the record date of such dividend or distribution or the effective date of such subdivision, combination or reclassification.

If after an adjustment the Holder upon exercise of any Warrants may receive shares of two or more classes of capital stock of the Company, the board of directors of the Company shall determine the allocation of the adjusted Exercise Price between the classes of capital stock. After such allocation, the Exercise Rate and the Exercise Price of each such class of capital stock shall thereafter be subject to adjustment on terms comparable to those applicable to Common Stock in this Section 4.

-3-

Such adjustment shall be made successively whenever any event listed above shall occur.

(b) Adjustment for Certain Issuances of Common Stock. If the Company issues or sells to any Person shares of its Common Stock or distributes any rights, options or warrants entitling any Person to purchase shares of Common Stock, or any rights, warrants or options or other securities convertible into or exchangeable for Common Stock, in each case, at a price per share less than the Current Market Value on the record date for determining entitlements to participate in such issuance, sale or distribution (the “Time of Determination”), the Exercise Rate shall be adjusted in accordance with the formula:

and the Exercise Price shall be adjusted in accordance with the following formula:

where:

E’ = the adjusted Exercise Rate.

E = the Exercise Rate immediately prior to the Time of Determination for any such issuance, sale or distribution.

EP’ = the Adjusted Exercise Price.

EP = the Exercise Price immediately prior to the Time of Determination for any such issuance, sale or distribution.

O = the number of Fully Diluted Shares (as defined below) outstanding immediately prior to the Time of Determination for any such issuance, sale or distribution.

N = the number of additional shares of Common Stock issued, sold or issuable upon exercise of such rights, options or warrants or other convertible or exchangeable securities.

P = the per share price received and receivable by the Company in the case of any issuance or sale of Common Stock or rights, options or warrants or other convertible or exchangeable securities inclusive of the exercise price per share of Common Stock payable upon exercise of such rights, options or warrants or other convertible or exchangeable securities.

-4-

M = the Current Market Value per share of Common Stock on the Time of Determination for any such issuance, sale or distribution.

For purposes of this Section 4 the term “Fully Diluted Shares” shall mean (i) the shares of Common Stock outstanding as of a specified date, and (ii) the shares of Common Stock into or for which rights, options, warrants or other convertible or exchangeable securities outstanding as of such date are exercisable, convertible or exchangeable (other than the Warrants or any of the other Authorized Warrants).

The adjustments shall be made successively whenever any such rights, options or warrants or other convertible or exchangeable securities are issued and shall become effective immediately after the relevant Time of Determination. Notwithstanding the foregoing, the Exercise Rate and the Exercise Price shall not be subject to adjustment in connection with (i) the issuance of any shares of the Company’s capital stock upon exercise of any such rights, options or warrants or other convertible or exchangeable securities which have previously been the subject of an adjustment under this Agreement for which the required adjustment has been made, (ii) any exercise of the Warrants or any of the other Authorized Warrants, (iii) any issuance or sale of any Common Stock or securities convertible or exercisable in to Common Stock pursuant to rights, options, warrants or other convertible or exchangeable securities outstanding as of the date of initial issuance of the Warrants, (iv) any issuance or sale to any director, officer, employee, consultant or advisor of the Company or its subsidiaries, in such person’s capacity as such, of shares of Common Stock or any rights, options or warrants entitling any director, officer, employee, consultant or advisor, in such person’s capacity as such, to purchase shares of Common Stock, or otherwise convertible into or exchangeable for Common Stock occurring on or after the date of initial issuance of the Warrants to the extent such issuance or sale is made pursuant to the terms of one or more stock option plans or similar agreements as in effect on the date of initial issuance of the Warrants or is otherwise approved by the board of directors of the Company, (v) any issuance of Common Stock as consideration for the acquisition of another company or business (whether through a purchase of securities, a merger, consolidation, purchase of assets or otherwise), (vi) any issuance of securities of the Company in a Public Offering or (vii) any securities issued as a dividend on the then outstanding Common Stock. If at the end of the period during which any such rights, options or warrants or other convertible or exchangeable securities are exercisable, not all rights, options or warrants or other convertible or exchangeable securities shall have been exercised, the Exercise Rate and the Exercise Price shall be immediately readjusted to what they would have been if “N” in each of the above formulas had been the number of shares actually issued with respect thereto.

Notwithstanding the foregoing, this Section 4(b) shall not apply with respect to an issuance of New Securities if the Holder shall be entitled to exercise pre-emptive rights pursuant to Section 5 hereof with respect to such issuance of New Securities (and the Company shall not have elected to cause this Section 4(b) to apply to such New Securities as provided for in Section 5).

-5-

(c) Adjustment for Other Distributions. If the Company distributes to holders of its Common Stock (i) any evidences of indebtedness of the Company or any of its subsidiaries, (ii) any assets of the Company or any of its subsidiaries (whether in cash, property or otherwise), or (iii) any rights, options or warrants to acquire any of the foregoing or to acquire any other securities of the Company, unless a Holder Distribution Election (as defined below) shall have been made with respect to such distribution, the Exercise Rate shall be adjusted in accordance with the following formula:

and the Exercise Price shall be decreased (but not increased) in accordance with the following formula:

where:

E’ = the adjusted Exercise Rate.

E = the current Exercise Rate on the record date referred to in this paragraph (c) below.

EP’ = the Adjusted Exercise Price.

EP = the current Exercise Price on the record date referred to in this paragraph (c) below.

M = the Current Market Value per share of Common Stock on the record date referred to in this paragraph (c) below.

F = the fair market value (as determined in good faith by the Company’s board of directors) on the record date referred to in this paragraph (c) below of the indebtedness, assets, rights, options or warrants distributable in respect of one share of Common Stock.

The adjustments shall be made successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of stockholders entitled to receive the distribution. If any adjustment is made pursuant to clause (iii) above of this subsection (c) as a result of the issuance of rights, options or warrants and at the end of the period during which any such rights, options or warrants are exercisable, not all such rights, options or warrants shall have been exercised, the Exercise Rate and the Exercise Price shall be immediately readjusted as if “F” in the above formula was the fair market value on the record date of the indebtedness or assets actually distributed upon exercise of such rights, options or warrants divided by the number of shares of Common Stock outstanding on the record date. Notwithstanding anything to the contrary contained in this subsection (c), if “M-F” in the above formula is less than $1.00 (or is a negative number) then in lieu of the adjustment otherwise required by this subsection (c), the Company may elect to distribute to the Holder, upon exercise of any Warrants, the evidences of indebtedness, assets, rights, options or warrants which would have been distributed to such Holder had such Warrants been exercised immediately prior to the record date for such distribution.

-6-

Notwithstanding the foregoing, a Holder may, in lieu of the adjustments described above in this subsection (c), elect to receive a distribution from the Company of its proportionate share of the evidences of indebtedness, assets, rights, options or warrants, as the case may be, which would have been distributed to such Holder had such Warrants been exercised immediately prior to the record date for such distribution (a “Holder Distribution Election”); provided that such Holder shall have notified the Company in writing of such election no later than 10 days after receipt of notice thereof from the Company pursuant to Section 4(f).

This subsection does not apply to rights, options or warrants referred to in subsection (b) of this Section 4.

(d) The following provisions shall be applicable to the making of adjustments of the Exercise Price and Exercise Rate hereinbefore provided for in this Section 4:

(i) The sale or other disposition of any issued shares of Common Stock owned or held by or for the account of the Company shall be deemed an issuance thereof for the purposes of this Section 4.

(ii) The adjustments required by the preceding paragraphs of this Section 4 shall be made whenever and as often as any specified event requiring an adjustment shall occur, except as otherwise expressly provided herein. For the purpose of any adjustment, any specified event shall be deemed to have occurred at the close of business on the date of its occurrence.

(iii) In computing adjustments under this Section 4 fractional interests in Common Stock shall be taken into account to the nearest one-thousandth (.001) of a share and shall be aggregated until they equal one whole share.

(iv) If the Company shall take a record of the holders of its Common Stock for the purpose of entitling them to receive any item described in Sections 4(a) through 4(c) hereof, but abandon its plan to pay or deliver such item, then no adjustment shall be required by reason of the taking of such record and any such adjustment previously made in respect thereof shall be rescinded and annulled.

-7-

(v) The consideration for any additional shares of Common Stock issuable pursuant to any options, warrants or other rights to subscribe for or purchase the same shall be the consideration received or receivable by the Company for issuing such options, warrants or other rights, plus the additional consideration payable to the Company upon the exercise of such options, warrants or other rights. The consideration for any additional shares of Common Stock issuable pursuant to the terms of any convertible or exchangeable securities shall be the consideration received or receivable by the Company for issuing any options, warrants or other rights to subscribe for or purchase such convertible or exchangeable securities, plus the consideration paid or payable to the Company in respect of the subscription for or purchase of such convertible or exchangeable securities, plus the additional consideration, if any, payable to the Company upon the exercise of the right of conversion, exercise or exchange of such convertible or exchangeable securities. In case of the issuance at any time of any additional shares of Common Stock or convertible or exchangeable securities in payment or satisfaction of any dividend upon any class of stock other than Common Stock, the Company shall be deemed to have received for such additional shares of Common Stock or convertible or exchangeable securities a consideration equal to the amount of such dividend so paid or satisfied.

(e) (i) [reserved]

(ii) In case of any capital reorganization, other than in the cases referred to in Section 4(a), (b) or (c) hereof and other than any capital reorganization that does not result in any reclassification of the outstanding shares of Common Stock into shares of other stock or other securities or property, or the consolidation or merger of the Company with or into another corporation (other than a merger or consolidation in which the Company is the continuing corporation and which does not result in any reclassification of the outstanding shares of Common Stock into shares of other stock or other securities or property), or the sale of all or substantially all of the assets of the Company (collectively such actions being hereinafter referred to as “Reorganizations”), there shall thereafter be deliverable upon exercise of any Warrant (in lieu of the number of shares of Common Stock theretofore deliverable) the number of shares of stock or other securities or property to which a holder of the number of shares of Common Stock that would otherwise have been deliverable upon the exercise of such Warrant would have been entitled upon such Reorganization if such Warrant had been exercised in full immediately prior to such Reorganization. In case of any Reorganization, appropriate adjustment, as determined in good faith by the board of directors of the Company, whose determination shall be described in a duly adopted resolution certified by the Company’s Secretary or Assistant Secretary, shall be made in the application of the provisions herein set forth with respect to the rights and interests of the Holder so that the provisions set forth herein shall thereafter be applicable, as nearly as possible, in relation to any such shares or other securities or property thereafter deliverable upon exercise of Warrants.

-8-

The Company shall not effect any such Reorganization unless prior to or simultaneously with the consummation thereof the successor corporation (if other than the Company) resulting from such Reorganization or the corporation or other entity purchasing such assets shall (i) expressly assume, by a supplemental warrant or other acknowledgment executed and delivered to the Holder, the obligation to deliver to the Holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, such Holder may be entitled to purchase, and the due and punctual performance and observance of each and every covenant, condition, obligation and liability under this Warrant Certificate to be performed and observed by the Company in the manner prescribed herein and (ii) if such Reorganization takes place prior to consummation by the Company of all of its registration obligations under the Registration Rights Agreement, enter into an agreement providing to the Holder rights and benefits substantially similar to those enjoyed by the Holder under the Registration Rights Agreement.

The foregoing provisions of this Section 4(e)(ii) shall apply to successive Reorganization transactions.

(f) (i) In case:

(A) the Company shall authorize the issuance to holders of shares of Common Stock of rights, options or warrants to subscribe for or purchase shares of Common Stock or of any other subscription rights or warrants; or

(B) the Company shall authorize the distribution to holders of shares of Common Stock of evidences of its indebtedness or assets or of rights, options or warrants to subscribe for or purchase any of the foregoing; or

(C) of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale of all or substantially all of the assets of the Company, or of any reclassification or change of Common Stock issuable upon exercise of the Warrants, or a tender offer or exchange offer for shares of Common Stock; or

(D) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; or

(E) the Company proposes to take any action that would require an adjustment to the Exercise Rate or Exercise Price pursuant to this Section 4;

then the Company shall give prompt written notice to the Holder at least 15 days prior to the applicable record date hereinafter specified, or the date of the event in the case of events for which there is no record date, by first-class mail, postage prepaid, a written notice stating (i) the date as of which the holders of record of shares of Common Stock to be entitled to receive any such shares, rights, options, warrants or distribution are to be determined, or (ii) the initial expiration date set forth in any tender offer or exchange offer for shares of Common Stock, or (iii) the date on which any such reclassification, consolidation, merger, sale, dissolution, liquidation or winding up is expected to become effective or consummated, and the date as of which it is expected that holders of record of shares of Common Stock shall be entitled to exchange such shares for securities or other property, if any, deliverable upon such reclassification, consolidation, merger, sale, dissolution, liquidation or winding up. The failure by the Company to give such notice or any defect therein shall not affect the legality or validity of any distribution, right, option, warrant, consolidation, merger, conveyance, dissolution, liquidation or winding up, or the vote upon any action.

-9-

(ii) Within five (5) days after the occurrence of an event resulting in an adjustment pursuant to this Section 4, the Company shall cause to be promptly mailed to the Holder (and upon the exercise hereof, to the exercising Holder) by first-class mail, postage prepaid, notice of each adjustment or adjustments to the Exercise Price and Exercise Rate effected since the date of the last such notice and a certificate of the Company’s Chief Financial Officer or Chief Accounting Officer, setting forth the Exercise Price and Exercise Rate after such adjustment(s), a brief statement of the facts requiring such adjustment(s) and the computation by which such adjustment(s) was made.

(g) The occurrence of a single event shall not trigger an adjustment of the Exercise Price and Exercise Rate under more than one paragraph of this Section 4.

5. Preemptive Rights.

(a) If the Company issues or sells or authorizes the issuance or sale of any New Securities (as defined below) at a price per share less than the Current Market Value, unless the Company shall have delivered to the Holder a written notice stating that with respect to such issuance or sale it has determined that Section 4(b) and not this Section 5 shall apply to such issuance or sale, the Company shall offer to Holder a portion of such New Securities (and if more than one class of securities is included in the New Securities, then a portion of the amount of each such class of securities included in the New Securities) equal to the quotient determined by dividing (A) the number of shares of Common Stock on an as-exercised and fully diluted basis held by such Holder by (B) the aggregate amount of all shares of Common Stock on an as-exercised and fully diluted basis, in each case determined before giving effect to the issuance of New Securities (for such Holders, its “Pre-Dilution Ratio”).

-10-

(b) Holder shall be entitled to purchase up to its Pre-Dilution Ratio of such New Securities on the same terms as such other New Securities are offered and sold either, at the Company’s option, (i) on the date the sale of the New Securities to the other purchasers is consummated (the “Original Closing Date”) or (ii) on a date (the “Holder Closing Date”) within ten days after the Original Closing Date, and the Company shall be required, in each case, to provide the notice to the Holder that is applicable to such sale. If the Company shall deliver written notice in connection with this Section 5 to the Holder no less than 30 days prior to the scheduled closing date for the consummation of such issuance of New Securities which notice shall describe in reasonable details the terms of such proposed issuance and shall include drafts of all relevant transaction documentation, then, if the Holder elects to participate, the Holder will purchase up to its Pre-Dilution Ratio of the New Securities on the Original Closing Date. If the Company shall deliver written notice in connection with this Section 5 to the Holder other than as set forth in the preceding sentence, it shall deliver written notice no less than 30 days prior to the Holder Closing Date, and then, if the holder elects to participate, the Holder will purchase up to its Pre-Dilution Ratio of the New Securities on the Holder Closing Date. If the Holder elects to participate and will purchase up to its Pre-Dilution Ratio of the New Securities on the Original Closing Date, it shall deliver written notice to the Company no later than 15 days following receipt of notice from the Company indicating the number of New Securities (not to exceed the product of the number of New Securities to be issued or sold and the Pre-Dilution Ratio) it desires to purchase (which notice can indicate one or more conditions to any obligation of Holder to purchase such New Securities). If the Holder elects to participate and will purchase up to its Pre-Dilution Ratio of the New Securities on the Holder Closing Date, it shall deliver written notice to the Company no later than 15 days following receipt of notice from the Company indicating the number of New Securities (not to exceed the product of the number of New Securities to be issued or sold and the Pre-Dilution Ratio) it desires to purchase (which notice can indicate one or more conditions to any obligation of Holder to purchase such New Securities). If Holder participates in such purchase it shall execute agreements (including any representations or warranties contained therein) on substantially the same terms as those executed by other purchasers of New Securities. The purchase price for all New Securities offered to Holder shall be payable on the Original Closing Date or Holder Closing Date, as applicable, and in cash by wire transfer of immediately available funds to an account designated by the Company.

(c) For purposes hereof, “New Securities” means any equity securities of the Company, or any securities containing options or rights to acquire equity securities of the Company, other than (i) securities issued as a dividend on the then outstanding Common Stock, (ii) securities issued pursuant to exercise, conversion or exchange of securities or rights outstanding on the date hereof or previously issued by the Company subject to this Section 5 (including pursuant to an exclusion from the definition of New Securities in any of clauses (i) through (vi) of this definition of New Securities), (iii) securities of the Company issued as consideration for the acquisition of another company or business (whether through a purchase of securities, a merger, consolidation, purchase of assets or otherwise), (iv) securities of the Company issued in a Public Offering, (v) shares of Common Stock or any rights, options or warrants entitling any director, officer, employee, consultant or advisor of the Company or its subsidiaries, in such person’s capacity as such, to purchase shares of Common Stock, or otherwise convertible into or exchangeable for Common Stock issued or sold to any director, officer, employee, consultant or advisor of the Company or its subsidiaries, in such person’s capacity as such, on or after the date of initial issuance of the Warrants to the extent such issuance or sale is made pursuant to the terms of one or more stock option plans or similar agreements as in effect on the date of initial issuance of the Warrants or is otherwise approved by the board of directors of the Company, or (vi) securities issued upon the exercise of any Warrants or any of the other Authorized Warrants.

-11-

Notwithstanding the foregoing, this Section 5 shall not apply with respect to an issuance of New Securities if the Holder shall be entitled to the adjustments set forth in Section 4 hereof.

6. Taxes on Conversion. The issuance of certificates for Warrant Shares upon the exercise of the Warrants shall be made without charge to the Holder exercising the Warrants for any issue or stamp tax in respect of the issuance of such certificates, and such certificates shall be issued in the respective names of, or in such names as may be directed by, the Holder; provided, however, that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate in a name other than that of the Holder, and the Company shall not be required to issue or deliver such certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the reasonable satisfaction of the Company that such tax has been paid.

7. Limitation of Liability. No provision hereof in the absence of the exercise of the Warrants by the Holder and no enumeration herein of the rights or privileges of the Holder shall give rise to any liability on the part of the Holder for the Exercise Price of the Warrant Shares or as a stockholder of the Company, whether such liability is asserted by the Company or by any creditor of the Company. Upon exercise of Warrants the Holder will have the right to vote the Common Stock received upon such exercise. No Holder shall be entitled to vote or be deemed the holder of Common Stock (or any other securities as may be issuable upon the exercise of the Warrants) nor shall anything contained herein be construed to confer upon the Holder the rights of a stockholder of the Company or the right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or give or withhold consent to any corporate action or to receive notice of meetings or other actions affecting stockholders or to receive dividends, distributions or subscription rights or otherwise (except as provided herein), until the Warrants shall have been exercised in accordance with the terms and conditions of the Warrants.

8. Closing of Books. The Company will at no time close its transfer books against the transfer of the Warrants or of any Warrant Shares issued or issuable upon the exercise of the Warrants in any manner that interferes with the timely exercise hereof. The Company shall deem and treat the Holder as the absolute owner of the Warrants for all purposes, including without limitation for the purpose of exercise thereof. The Company agrees that, upon exercise of the Warrants in accordance with the terms hereof (including receipt by the Company of payment of the aggregate Exercise Price therefor), the shares so purchased shall be deemed to be issued to such Holder as the record owner of such shares as of the close of business on the date on which the Warrants shall have been exercised and the Holder shall be deemed for all purposes a stockholder of the Company with respect to such shares as though the certificate for such shares had been issued on the date of such exercise.

-12-

9. Restrictions on Transfer.

A. Restrictive Legends. Each certificate for any Warrant Shares issued upon the exercise of the Warrants, and each stock certificate issued upon the transfer of any such Warrant Shares (except as otherwise permitted by this Section 9) shall be stamped or otherwise imprinted with a legend in substantially the following form:

THESE SHARES MAY NOT BE TRANSFERRED EXCEPT UPON THE CONDITIONS SPECIFIED IN THE WARRANT CERTIFICATE PURSUANT TO WHICH THESE SHARES HAVE BEEN ISSUED, AND NO TRANSFER OF THESE SHARES SHALL BE VALID OR EFFECTIVE UNLESS AND UNTIL SUCH CONDITIONS SHALL HAVE BEEN COMPLIED WITH.

THESE WARRANTS AND SUCH SHARES MAY NOT BE TRANSFERRED EXCEPT UPON THE CONDITIONS SPECIFIED IN THIS WARRANT CERTIFICATE, AND NO TRANSFER OF THESE WARRANTS OR SUCH SHARES SHALL BE VALID OR EFFECTIVE UNLESS AND UNTIL SUCH CONDITIONS SHALL HAVE BEEN COMPLIED WITH.

B. Termination of Restrictions. The restrictions imposed by Section 9A upon the transferability of Warrants and Warrant Shares shall apply as to the Warrants and any Warrant Shares until (a) such securities shall have been effectively registered under the Securities Act and disposed of in accordance with the registration statement covering such securities, or (b) such time as, in the reasonable opinion of counsel for the Company, or in the written opinion of counsel for the Holder reasonably acceptable to the Company, such restrictions are not required in order to comply with the Securities Act. Whenever such restrictions shall terminate as to any Warrants or Warrant Shares, the Holder shall be entitled to receive from the Company, without expense, new certificates of like tenor not bearing the restrictive legends set forth in Section 9A.
