Section 2.2 Form, Denomination and Date of Warrants. (a) The Warrant Certificates shall be substantially in the form of Exhibit A hereto. The Warrants shall be numbered, lettered or otherwise distinguished in such manner or in accordance with such plans as the officers of the Company executing the same may determine with the approval of the Warrant Agent. Each Warrant shall be dated the date of its authentication. Any of the Warrants may be issued with appropriate insertions, omissions, substitutions and variations, and may have imprinted or otherwise reproduced thereon such legend or legends, not inconsistent with the provisions of this Agreement, as may be required to comply with any law or with any rules or regulations pursuant thereto, or with the rules of any securities market in which the Warrants are admitted to trading, or to conform to general usage. All Warrants shall be otherwise substantially identical except as to denomination and as provided herein.

(b) Purchasers of Warrants will receive certificated Warrants bearing the Restricted Warrant Legend (“Restricted Warrants”). Restricted Warrants will bear the Restricted Warrant Legend unless removed in accordance with Section 2.4.

Upon the occurrence of an Effective Registration, all requirements with respect to legends on Warrants will cease to apply, and certificated Warrants without legends will be available to the Holders.

Section 2.3 Execution and Delivery of Warrant Certificates. (a) Warrant Certificates evidencing the Warrants which may be countersigned and delivered under this Agreement are limited to Warrant Certificates evidencing 546,400 Warrants, except for Warrant Certificates countersigned and delivered upon registration of transfer of, or in exchange for, or in lieu of, one or more previously countersigned Warrant Certificates pursuant to Sections 2.6, 3.2(e), 7 and 9.

(b) At any time and from time to time on or after the date of this Agreement, Warrant Certificates evidencing the Warrants may be executed by the Company and delivered to the Warrant Agent for countersignature, and the Warrant Agent shall, upon receipt of a Company Order and at the direction of the Company set forth therein, countersign and deliver such Warrant Certificates to the Company for issuance. The Warrant Agent is further hereby authorized to countersign and deliver Warrant Certificates as required by this Section 2.3 or by Sections 2.2, 2.6, 3.2(e), 7 or 9.

In case any officer of the Company whose signature shall have been placed upon any of the Warrant Certificates shall cease to be such officer of the Company before countersignature by the Warrant Agent and issue and delivery thereof, such Warrant Certificates may, nevertheless, be countersigned by the Warrant Agent and issued and delivered with the same force and effect as though such person had not ceased to be such officer of the Company, and any Warrant Certificate may be signed on behalf of the Company by such person as, at the actual date of the execution of such Warrant Certificate, shall be a proper officer of the Company, although at the date of the execution of this Agreement any such person was not such an officer.

Section 2.4 Transfer and Exchange. (a) If a holder of a Restricted Warrant wishes at any time to transfer such Restricted Warrant to a Person who wishes to take delivery thereof in the form of a Restricted Warrant, such holder may, subject to the restrictions on transfer set forth herein and in such Restricted Warrant, cause the exchange of such Restricted Warrants for one or more Restricted Warrants of any authorized denomination or denominations and exercisable for the same aggregate number of Warrant Shares. Upon receipt by the Warrant Agent at its Corporate Agency Office of (1) such Restricted Warrant, duly endorsed as provided herein, (2) instructions from such holder directing the Warrant Agent to authenticate and deliver one or more Restricted Warrants exercisable for the same aggregate number of Warrant Shares as the Restricted Warrant to be exchanged, such instructions to contain the name or names of the designated transferee or transferees, the authorized denomination or denominations of the Restricted Warrants to be so issued and appropriate delivery instructions, (3) a certificate in the form of Exhibit B attached hereto given by the Person acquiring the Restricted Warrants, to the effect set forth therein, and (4) an opinion of counsel to the transferor of such Restricted Warrant substantially to the effect set forth in Exhibit C hereto, to the effect set forth therein, then the Warrant Agent shall cancel or cause to be cancelled such Restricted Warrant and, concurrently therewith, the Company shall execute, and the Warrant Agent shall authenticate and deliver, one or more Restricted Warrants to the effect set forth therein, in accordance with the instructions referred to above.

(b) If Warrants are issued upon the transfer, exchange or replacement of Warrants bearing the Restricted Warrant Legend, or if a request is made to remove such Restricted Warrant Legend, the Warrants so issued shall bear the Restricted Warrant Legend; or

the Restricted Warrant Legend shall not be removed, as the case may be, unless (i) there is delivered to the Company and the Warrant Agent satisfactory evidence, which shall include an opinion of counsel as may be reasonably required by the Company and the Warrant Agent to the effect that neither the Restricted Warrant Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of the Securities Act or, with respect to Restricted Warrants, that such Warrants are not “restricted” within the meaning of Rule 144 under the Securities Act or (ii) there is an Effective Registration with respect to the Warrants then in effect or the Warrants as to which the Restricted Warrant Legend is sought to be removed have been disposed of in accordance with the Registration Statement. Upon (i) provision of such satisfactory evidence, or (ii) notification by the Company to the Warrant Agent of an Effective Registration with respect to the Warrants and an opinion of counsel to that effect, the Warrant Agent, at the direction of the Company, shall authenticate and deliver Warrant Certificates that do not bear the Restricted Warrant Legend.

Promptly after delivering to the Warrant Agent notice of the Effective Registration and an opinion of counsel to that effect, the Company shall cause to be delivered to the Warrant Agent certificates for Warrants without legends and the Warrant Agent shall authenticate and deliver certificated Warrants without legends to Holders presenting their certificated Warrants for exchange to transferees of Warrants covered by the Registration Statement in the names and denominations specified by them.

ARTICLE 3

EXERCISE, REDEMPTION AND EXPIRATION OF WARRANTS

Section 3.1 Right to Acquire Warrant Shares Upon Exercise. Each Warrant Certificate shall, when countersigned by the Warrant Agent, entitle the Holder thereof, subject to the provisions thereof and of this Agreement, to acquire from the Company, for each Warrant evidenced thereby, four (4) Warrant Shares for each 10 Shares issued to such Purchaser on the Closing Date at the Warrant Price, subject to adjustment as provided in this Agreement. The Warrant Price shall be adjusted from time to time as required by Section 6.1.

Section 3.2 Exercise and Expiration of Warrants. (a) Exercise of Warrants. Subject to the terms and conditions set forth herein, including, without limitation, the exercise procedure described in Section 3.2(c), a Holder of a Warrant Certificate may exercise all or any whole number of the Warrants evidenced thereby, on any Business Day from and after February 6, 2008 until 5:00 p.m., New York City time, on the Expiration Date (subject to earlier expiration pursuant to Article 5) for the Warrant Shares purchasable thereunder.

(b) Expiration of Warrants. The Warrants shall terminate and become void as of 5:00 p.m., New York time on the Expiration Date, subject to earlier expiration in accordance

with Article 5. In the event that the Warrants are to expire by reason of Article 5, the term “Expiration Date” shall mean such earlier date for all purposes of this Agreement.

(i) Cash Exercise. The Holder may deliver to the Warrant Agent at the Corporate Agency Office (A) a written notice of such Holder’s election to exercise Warrants, duly executed by such Holder in the form set forth on the reverse of, or attached to, such Warrant Certificate, which notice shall specify the number of Warrant Shares to be purchased, (B) the Warrant Certificate evidencing such Warrants and (C) to Computershare, a sum equal to the aggregate Warrant Price for the Warrant Shares into which such Warrants are being exercised, which sum shall be paid in any combination elected by such Holder of (x) certified or official bank checks in New York Clearing House funds payable to the order of the Company and delivered to Computershare at the Corporate Agency Office, or (y) to Computershare, wire transfers in immediately available funds to the account of the Company at such banking institution as the Company shall have given notice to the Warrant Agent and the Holders in accordance with Section 13.1(b); or

If fewer than all the Warrants represented by a Warrant Certificate are exercised, such Warrant Certificate shall be surrendered and a new Warrant Certificate of the same tenor and for the number of Warrants which were not exercised shall be executed by the Company. The Warrant Agent shall countersign the new Warrant Certificate, registered in such name or names, subject to the provisions of Article 9, as may be directed in writing by the Holder, and shall deliver the new Warrant Certificate to the Person or Persons in whose name such new Warrant Certificate is so registered. The Company, whenever required by the Warrant Agent, will supply the Warrant Agent with Warrant Certificates duly executed on behalf of the Company for such purpose.

(ii) Cashless Exercise. In lieu of exercising the Warrant, the Holder may elect to receive shares of Common Stock equal to the value of the Warrant (or the portion thereof being canceled) by surrender of the Warrant at the principal office of the Company together with notice of such election, in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula:

	X =		Y (A-B)
			A

	Where X =		the number of shares of Common Stock to be issued to the Holder.

	Y =		the number of shares of Common Stock purchasable under the Warrant.

	A =		the fair market value of one share of the Company’s Common Stock.

	B =		the Exercise Price (as adjusted to the date of such calculation).

For purposes of the Warrant, the fair market value of the Company’s Common Stock shall be determined as follows:

a. If the Common Stock is listed on a National Securities Exchange or admitted to unlisted trading privileges on such exchange or listed for trading on the Nasdaq system, the current market value shall be the last reported sale price of the Common Stock on such exchange or system on the last business day prior to the date of exercise of the Warrant or, if no such sale is made on such day, the average of the closing bid and asked prices for such day on such exchange or system; or

b. If the Common Stock is not so listed or admitted, the current market shall be the average of the closing bid and asked prices as quoted by the OTC Bulletin Board; or

c. If the Common Stock is not so listed or admitted to unlisted trading privileges, the current market value shall be the mean of the last reported bid and asked prices reported by the National Quotation Bureau, Inc. on the last business day prior to the date of the exercise of the Warrant; or

d. If the Common Stock is not so listed or admitted to unlisted trading privileges and bid and asked prices are not so reported, the current market value shall be an amount, not less than book value thereof as at the end of the most recent fiscal year of the Company ending prior to the date of the exercise of the Warrant, determined in such reasonable manner as may be prescribed by the Board of Directors of the Company.

(d) Issuance of Warrant Shares. Upon surrender of a Warrant Certificate evidencing Warrants in conformity with the foregoing provisions and payment of the Warrant Price in respect of the exercise of one or more Warrants evidenced thereby, the Warrant Agent shall, when such payment is received, deliver to the Company the notice of exercise received pursuant to Section 3.2(c), and, in accordance with Section 3.3, deliver or deposit all funds received as instructed in writing by the Company and advise the Company by means of a weekly activity report of the amount of funds so deposited to its account. The Company shall thereupon, as promptly as practicable, and in any event within three Business Days after receipt by the Company of such notice of exercise, execute or cause to be executed and deliver or cause to be delivered to the Recipient (as defined below) a certificate or certificates representing the aggregate number of Warrant Shares issuable upon such exercise (based upon the aggregate number of Warrants so exercised), determined in accordance with Section 3.6, together with an amount in cash in lieu of any fractional share(s) determined in accordance with Section 6.4. The certificate or certificates so delivered shall be, to the extent possible, in such denomination or denominations as such Holder shall request in such notice of exercise and shall be registered or otherwise placed in the name of, and delivered to, the Holder or, such other Person as shall be designated by the Holder in such notice (the Holder or such other Person being referred to herein as the “Recipient”).

(e) Time of Exercise. A Warrant shall be deemed to have been exercised immediately prior to the close of business on the date on which all requirements set forth in Section 3.2(c) applicable to such exercise have been satisfied. Subject to Section 6.1(e)(iv), certificate(s) evidencing the Warrant Shares issued upon the exercise of such Warrant shall be

deemed to have been issued and, for all purposes of this Agreement, the Recipient shall, as between such Person and the Company, be deemed to be and entitled to all rights of the holder of record of such Warrant Shares as of such time.

Section 3.3 Application of Funds Upon Exercise of Warrants. Any funds delivered to Computershare upon exercise of any Warrant(s) shall be held by Computershare pending delivery to the Company. Computershare shall promptly deliver and pay to or upon the written order of the Company all funds received by it upon the exercise of any Warrants by bank wire transfer to an account designated by the Company or as Computershare otherwise may be directed in writing by the Company.

Section 3.4 Payment of Taxes. The Company shall pay any and all taxes (other than income taxes) and other charges that may be payable in respect of the issue or delivery of Warrant Shares on exercise of Warrants pursuant hereto. Neither the Company nor the Warrant Agent shall be required, however, to pay any tax or other charge imposed in respect of any transfer involved in the issue and delivery of any certificates for Warrant Shares or payment of cash to any Recipient other than the Holder of the Warrant Certificate surrendered upon the exercise of a Warrant, and in case of such transfer or payment, the Warrant Agent and the Company shall not be required to issue or deliver any certificate or, in the case of Computershare, pay any cash until (a) such tax or charge has been paid or an amount sufficient for the payment thereof has been delivered to the Warrant Agent or the Company or (b) it has been established to the Company’s satisfaction that any such tax or other charge that is or may become due has been paid.

Section 3.5 Surrender of Certificates. Any Warrant Certificate surrendered for exercise shall, if surrendered to the Company, be delivered to the Warrant Agent, and all Warrant Certificates surrendered or so delivered to the Warrant Agent shall be promptly cancelled by such Warrant Agent and shall not be reissued by the Company. Warrant Certificates shall be retained by the Company in accordance with applicable law.

Section 3.6 Shares Issuable. The number of Warrant Shares “issuable upon exercise” of Warrants at any time shall be the number of Warrant Shares into which such Warrants are then exercisable. The number of Warrant Shares “into which each Warrant is exercisable” initially shall be one share, subject to adjustment as provided in Section 6.1.

ARTICLE 4

REGISTRATION RIGHTS

The Warrantholders and holders of Warrant Shares shall have the registration rights provided for in the Registration Rights Agreement. The Company shall keep copies of the Registration Rights Agreement available for inspection by the Holders during normal business hours at its office. The Company shall supply the Warrant Agent from time to time with such numbers of copies of the Registration Rights Agreement as the Warrant Agent may request.

ARTICLE 5

DISSOLUTION, LIQUIDATION OR WINDING UP

If, on or prior to the Expiration Date, the Company (or any other Person controlling the Company) shall propose a voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, the Company shall give written notice thereof to the Warrant Agent and all Holders of Warrant Certificates in the manner provided in Article 13 prior to the date on which such transaction is expected to become effective or, if earlier, the record date for such transaction. Such notice shall also specify the date as of which the holders of record of the Common Stock shall be entitled to exchange their shares for monies, securities or other property deliverable upon such dissolution, liquidation or winding up, as the case may be, on which date each Holder of Warrant Certificates shall be entitled to receive the monies, securities or other property which such Holder would have been entitled to receive had such Holder been the holder of record of the Warrant Shares into which the Warrants were exercisable immediately prior to such dissolution, liquidation or winding up (net of the then applicable Warrant Price) and the rights to exercise the Warrants shall terminate.

In case of any such voluntary or involuntary dissolution, liquidation or winding up of the Company, the Company shall deposit with the Warrant Agent any monies, securities or other property which the Holders are entitled to receive under this Agreement, together with a Company Order as to the distribution thereof. After receipt of such deposit from the Company and after any Holder has surrendered a Warrant Certificate to the Warrant Agent, the Warrant Agent shall make payment in the appropriate amount to such Person or Persons as it may be directed in writing by the Holder surrendering such Warrant Certificate. The Warrant Agent shall not be required to pay interest on any money deposited pursuant to the provisions of this Article 5 except such as it shall agree with the Company to pay thereon. Any monies, securities or other property which at any time shall be deposited by the Company or on its behalf with the Warrant Agent pursuant to this Article 5 shall be, and are hereby, assigned, transferred and set over to the Warrant Agent in trust for the purpose for which such monies, securities or other property shall have been deposited; provided that monies, securities or other property need not be segregated from other monies, securities or other property held by the Warrant Agent except to the extent required by law.

ARTICLE 6

ADJUSTMENTS

Section 6.1 Adjustments. The number of Warrant Shares into which each Warrant is exercisable and the Warrant Price shall be subject to adjustment from time to time after the date hereof in accordance (and only in accordance) with the provisions of this Article 6:

(a) Adjustment for Recapitalization, Reorganization, Consolidation, Merger, Etc. In case (i) the outstanding shares of the Common Stock shall be subdivided into a greater number of shares, (ii) a dividend or other distribution in Common Stock shall be paid in respect of Common Stock, (iii) the outstanding shares of Common Stock shall be combined into a smaller number of shares thereof, or (iv) any shares of the Company’s capital stock are issued by

reclassification of the Common Stock (including any reclassification upon a consolidation or merger in which the Company is the continuing corporation), the Exercise Price in effect immediately prior to such subdivision, combination or reclassification or at the record date of such dividend or distribution shall simultaneously with the effectiveness of such subdivision, combination or reclassification or immediately after the record date of such dividend or distribution be proportionately adjusted to equal the product obtained by multiplying the Exercise Price by a fraction, the numerator of which is the number of outstanding shares of Common Stock (on a fully diluted basis) after giving effect to such combination, subdivision, reclassification or dividend and the denominator of which is the number of outstanding shares of Common Stock (on a fully diluted basis) outstanding immediately prior to such combination, subdivision, reclassification or dividend.

(b) For purposes of the Warrant, “on a fully diluted basis” means that all outstanding options, rights or Warrants to subscribe for shares of Common Stock and all securities convertible into or exchangeable for shares of Common Stock (such options, rights, Warrants and securities are collectively referred to herein as “Convertible Securities”) and all options or rights to acquire Convertible Securities have been exercised, converted or exchanged.

(c) Whenever the Exercise Price per share is adjusted as provided in the immediately preceding paragraph, the number of shares of Common Stock purchasable upon conversion of the Warrant immediately prior to such Exercise Price adjustment shall be adjusted, effective simultaneous with the Exercise Price adjustment, to equal the product obtained (calculated to the nearest full share) by multiplying such number of shares of Common Stock by a fraction, the numerator of which is the Exercise Price per share in effect immediately prior to such Exercise Price adjustment and the denominator of which is the Exercise Price per share in effect upon such Exercise Price adjustment, which adjusted number of shares of Common Stock shall thereupon be the number of shares of Common Stock purchasable upon conversion of the Warrant until further adjusted as provided herein.

(d) Adjustment for Reorganization, Consolidation, Merger, Liquidation Etc. In case of any reorganization of the Company (or any other corporation, the securities of which are at the time receivable on the exercise of the Warrant) after the date hereof or in case after such date the Company (or any such other corporation) shall consolidate with or merge into another corporation or convey all or substantially all of its assets to another corporation or liquidate, then, and in each such case, the Holder of the Warrant upon the exercise thereof as provided in Section 1 at any time after the consummation of such reorganization, consolidation, merger, conveyance or liquidation, shall be entitled to receive, in lieu of the securities and property receivable upon the exercise of the Warrant prior to such consummation, the securities or property to which such Holder would have been entitled upon such consummation if such Holder had exercised the Warrant immediately prior thereto; in each such case, the terms of the Warrant shall be applicable to the securities or property receivable upon the exercise of the Warrant after such consummation.

(e) No Dilution. The Company will not, by amendment of its Certificate of Incorporation or through reorganization, consolidation, merger, dissolution, issue or sale of securities, sale of assets or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of the 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 action as may be necessary or appropriate in order to protect the rights of the Holder of the Warrant against dilution or other impairment. Without limiting the generality of the foregoing, while the Warrant is outstanding, the Company (a) will not permit the par value, if any, of the shares of Common Stock receivable upon the exercise of the Warrant to be above the amount payable therefor upon such exercise and (b) will take all such action as may be necessary or appropriate in order that the Company may validly and legally issue or sell fully paid and non-assessable shares of Common Stock upon the exercise of the Warrant.

(f) Certificate as to Adjustments. In each case of an adjustment in the number of shares of Warrant Shares receivable on the exercise of the Warrant, the Company at its expense will promptly compute such adjustment in accordance with the terms of the Warrant and prepare a certificate executed by an executive officer of the Company setting forth such adjustment and showing in detail the facts upon which such adjustment is based. The Company will forthwith mail a copy of each such certificate to the Holder.

(g) Notices of Record Date, Etc. In case:

(i) the Company shall take a record of the holders of its Common Stock for the purpose of entitling them to receive any dividend (other than a cash dividend at the same rate as the rate of the last cash dividend theretofore paid) or other distribution, or any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities, or to receive any other right; or

(ii) of any capital reorganization of the Company, any reclassification of the capital stock of the Company, any consolidation or merger of the Company with or into another corporation, or any conveyance of all or substantially all of the assets of the Company to another corporation; or

(iii) of any voluntary or involuntary dissolution, liquidation or winding up of the Company, then, and in each such case, the Company shall mail or cause to be mailed to each Holder of the Warrant at the time outstanding a notice specifying, as the case may be, (i) the date on which a record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right, or (ii) the date on which such reorganization, reclassification, consolidation, merger, conveyance, dissolution, liquidation or winding up is to take place, and the time, if any, is to be fixed, as to which the holders of record of Common Stock (or such other securities at the time receivable upon the exercise of the Warrant) shall be entitled to exchange their shares of Common Stock (or such other securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, conveyance, dissolution, liquidation or winding up. Such notice shall be mailed at least 20 days prior to the date therein specified and the Warrant may be exercised prior to said date during the term of the Warrant.

ARTICLE 7

LOSS OR MUTILATION

Upon (i) receipt by the Warrant Agent of an affidavit with respect to the ownership of and the loss, theft, destruction or mutilation of any Warrant Certificate and an open penalty surety bond satisfactory to the Warrant Agent holding both it and the Company harmless and other such security or indemnity as may be reasonably required to save each of them harmless and (ii) surrender, in the case of mutilation, of the mutilated Warrant Certificate to the Warrant Agent and cancellation thereof, then, in the absence of notice to the Company or the Warrant Agent that the Warrants evidenced thereby have been acquired by a bona fide purchaser, the Company shall execute and upon its written request the Warrant Agent shall countersign and deliver to the registered Holder of the lost, stolen, destroyed or mutilated Warrant Certificate, in exchange therefor or in lieu thereof, a new Warrant Certificate of the same tenor and for a like aggregate number of Warrants. At the written request of such registered Holder, the new Warrant Certificate so issued shall be retained by the Warrant Agent as having been surrendered for exercise, in lieu of delivery thereof to such Holder, and shall be deemed for purposes of Section 3.2 to have been surrendered for exercise on the date the conditions specified in clauses (i) and (ii) of the preceding sentence were first satisfied.

Upon the issuance of any new Warrant Certificate under this Article 7, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and other expenses (including the fees and expenses of the Warrant Agent and of counsel to the Company) in connection therewith.

Every new Warrant Certificate executed and delivered pursuant to this Article 7 in lieu of any lost, stolen or destroyed Warrant Certificate shall constitute an additional contractual obligation of the Company, whether or not the allegedly lost, stolen or destroyed Warrant Certificate shall be at any time enforceable by anyone, and shall be entitled to the benefits of this Agreement equally and proportionately with any and all other Warrant Certificates duly executed and delivered hereunder.

The provisions of this Article 7 are exclusive and shall preclude (to the extent lawful) all other rights or remedies with respect to the replacement of mutilated, lost, stolen, or destroyed Warrant Certificates.

The Company shall at all times reserve and keep available, free from preemptive rights, solely for issue upon the exercise of Warrants as herein provided, such number of its authorized but unissued Warrant Shares deliverable upon the exercise of Warrants as will be sufficient to permit the exercise in full of all outstanding Warrants. The Company covenants that all Warrant Shares will, at all times that Warrants are exercisable, be duly approved for listing subject to official notice of issuance on each securities exchange, if any, on which the Common Stock are then listed. The Company covenants that (i) all Warrant Shares that may be issued upon exercise

of Warrants shall, upon issuance, be duly and validly authorized, issued and fully paid and nonassessable and free of preemptive or similar rights, (ii) the Warrant Shares and the offering thereof are either registered or subject to a valid exemption from registration under the Securities Act and (iii) the stock certificates issued to evidence any such Warrant Shares will comply with the Delaware General Corporation Law and any other applicable law.

The Company hereby authorizes and directs its current and future transfer agents for the Common Stock at all times to reserve stock certificates for such number of authorized shares as shall be requisite for such purpose. The Warrant Agent is hereby authorized to requisition from time to time from any such transfer agents stock certificates required to honor outstanding Warrants upon exercise thereof in accordance with the terms of this Agreement, and the Company hereby authorizes and directs such transfer agents to comply with all such requests of the Warrant Agent. The Company will supply such transfer agents with duly executed stock certificates for such purposes. Promptly after the date of expiration of all of the Warrants in accordance with Section 3.2(c), the Warrant Agent shall certify to the Company the aggregate number of Warrants then outstanding, and thereafter no Warrant Shares shall be reserved in respect of such Warrants.

ARTICLE 9

WARRANT TRANSFER BOOKS

The Warrant Agent will maintain an office (the “Corporate Agency Office”) in the United States of America, where Warrant Certificates may be surrendered for registration of transfer or exchange and where Warrant Certificates may be surrendered for exercise of Warrants evidenced thereby, which office is Computershare Trust Company, N.A., 000 Xxxxxxxxxx Xxxx. — Xxxxx 0000, Xxxxxx Xxxx, X.X. 00000, on the date hereof. The Warrant Agent will give prompt written notice to all Holders of Warrant Certificates of any change in the location of such office.

The Warrant Certificates evidencing the Warrants shall be issued in registered form only. The Company shall cause to be kept at the office of the Warrant Agent designated for such purpose a warrant register (the “Warrant Register”) in which, subject to such reasonable regulations as the Warrant Agent may prescribe and such regulations as may be prescribed by law, the Company shall provide for the registration of Warrant Certificates and of transfers or exchanges of Warrant Certificates as herein provided.

Subject to Section 2.4, upon surrender for registration of transfer of any Warrant Certificate at the Corporate Agency Office, the Company shall execute, and the Warrant Agent shall countersign and deliver, in the name of the designated transferee or transferees, one or more new Warrant Certificates evidencing a like aggregate number of Warrants.

Subject to Section 2.4, (i) at the option of the Holder, Warrant Certificates may be exchanged at the office of the Warrant Agent upon payment of the charges hereinafter provided for other Warrant Certificates evidencing a like aggregate number of Warrants and (ii) whenever any Warrant Certificates are so surrendered for exchange, the Company shall execute, and the Warrant Agent shall countersign and deliver, the Warrant Certificates of the same tenor and

evidencing the same number of Warrants as evidenced by the Warrant Certificates surrendered by the Holder making the exchange.

All Warrant Certificates issued upon any registration of transfer or exchange of Warrant Certificates shall be the valid obligations of the Company, evidencing the same obligations, and entitled to the same benefits under this Agreement, as the Warrant Certificates surrendered for such registration of transfer or exchange.

Subject to Section 2.4, every Warrant Certificate surrendered for registration of transfer or exchange shall (if so required by the Company or the Warrant Agent) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Warrant Agent, duly executed by the Holder thereof or his attorney duly authorized in writing.

The Warrant Agent shall, upon request of the Company from time to time, deliver to the Company such reports of registered ownership of the Warrants and such records of transactions with respect to the Warrants and the Warrant Shares as the Company may request. The Warrant Agent shall also make available to the Company for inspection by the Company’s agents or employees, from time to time as the Company may request, such original books of accounts and records maintained by the Warrant Agent in connection with the issuance and exercise of Warrants hereunder, such inspections to occur at the Corporate Agency Office during normal business hours.

The Warrant Agent shall keep copies of this Agreement and any notices given to Holders hereunder available for inspection by the Holders during normal business hours at the Corporate Agency Office. The Company shall supply the Warrant Agent from time to time with such numbers of copies of this Agreement as the Warrant Agent may request.

The Warrant Agent may execute and exercise any of the rights and powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys, agents or employees, provided that reasonable care has been exercised in the selection and in the continued employment of any such attorney, agent or employee. The Warrant Agent shall not be under any obligation or duty to institute, appear in or defend any action, suit or legal proceeding in respect hereof, unless first indemnified to its satisfaction, but this provision shall not affect the power of the Warrant Agent to take such action as the Warrant Agent may consider proper, whether with or without such indemnity. The Warrant Agent shall promptly notify the Company in writing of any claim made or action, suit or proceeding instituted against it arising out of or in connection with this Agreement.

The Company shall perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further acts, instruments and assurances as may reasonably be required by the Warrant Agent in order to enable it to carry out or perform its duties under this Agreement.

The Warrant Agent shall act solely as agent of the Company hereunder and does not assume any obligation or relationship of agency or trust for or with any of the Holders or any beneficial owners of Warrants. The Warrant Agent shall not be liable except for the failure to perform such duties as are specifically set forth herein or specifically set forth in the Warrant Certificates, and no implied covenants or obligations shall be read into this Agreement against the Warrant Agent whose duties and obligations shall be determined solely by the express provisions hereof or the express provisions of the Warrant Certificates.

Section 11.3 Compensation, Reimbursement and Indemnification. The Company agrees to pay the Warrant Agent from time to time compensation for all fees and expenses relating to its services hereunder as the Company and the Warrant Agent may agree from time to time and to reimburse the Warrant Agent for reasonable expenses and disbursements, including reasonable counsel fees and expenses incurred in connection with the execution and administration of this Agreement. The Company further agrees to indemnify the Warrant Agent for and save it harmless against any losses, liabilities or reasonable expenses arising out of or in connection with the acceptance and administration of this Agreement, including the reasonable costs, legal fees and expenses of investigating or defending any claim of such liability, except that the Company shall have no liability hereunder to the extent that any such loss, liability or expense results from the Warrant Agent’s own gross negligence, bad faith or willful misconduct.

Section 11.4 Warrant Agent May Hold Company Securities. The Warrant Agent, any Countersigning Agent and any stockholder, director, officer or employee of the Warrant Agent or any Countersigning Agent may buy, sell or deal in any of the Warrants or other securities of the Company or its Affiliates, become pecuniarily interested in transactions in which the Company or its Affiliates may be interested, contract with or lend money to the Company or its Affiliates or otherwise act as fully and freely as though it were not the Warrant Agent or the Countersigning Agent, respectively, under this Agreement. Nothing herein shall preclude the Warrant Agent or any Countersigning Agent from acting in any other capacity for the Company or for any other legal entity.

Section 11.5 Resignation and Removal; Appointment of Successor.

The Company may remove the Warrant Agent upon thirty (30) days’ written notice, and the Warrant Agent shall thereupon in like manner be discharged from all further duties and liabilities hereunder, except as aforesaid. The Warrant Agent shall, at the expense of the Company, cause notice to be given in accordance with Section 13.1(b) to each Holder of a Warrant Certificate of said notice of resignation or notice of removal, as the case may be. Upon such resignation or removal, the Company shall appoint in writing a new Warrant Agent. If the Company shall fail to make such appointment within a period of thirty (30) calendar days after it has been notified in writing of such resignation by the resigning Warrant Agent or after such removal, then the Holder of any Warrant Certificate may apply to any court of competent jurisdiction for the appointment of a new Warrant Agent. Any new Warrant Agent, whether appointed by the Company or by such a court, shall be a corporation doing business under the laws of the United States or any state thereof in good standing, authorized under such laws to act as Warrant Agent, and having a combined capital and surplus of not less than $50,000,000. The combined capital and surplus of any such new Warrant Agent shall be deemed to be the combined capital and surplus as set forth in the most recent annual report of its condition published by such Warrant Agent prior to its

appointment, provided that such reports are published at least annually pursuant to law or to the requirements of a Federal or state supervising or examining authority. After acceptance in writing of such appointment by the new Warrant Agent, it shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as the Warrant Agent, without any further assurance, conveyance, act or deed; but if for any reason it shall be reasonably necessary or expedient to execute and deliver any further assurance, conveyance, act or deed, the same shall be done at the reasonable expense of the Company and shall be legally and validly executed and delivered by the resigning or removed Warrant Agent. Not later than the effective date of any such appointment, the Company shall file notice thereof with the resigning or removed Warrant Agent. Failure to give any notice provided for in this Section 11.5(a), however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Warrant Agent or the appointment of a new Warrant Agent, as the case may be.

(b) Any corporation into which the Warrant Agent or any new Warrant Agent that be merged, or any corporation resulting from any consolidation to which the Warrant Agent or any new Warrant Agent shall be a party, shall be a successor Warrant Agent under this Agreement without any further act, provided that such corporation would be eligible for appointment as successor to the Warrant Agent under the provisions of Section 11.5(a). Any such successor Warrant Agent shall promptly cause notice of its succession as Warrant Agent to be given in accordance with Section 13.1(b) to each Holder of a Warrant Certificate at such Holder’s last address as shown on the Warrant Register.

Section 11.6 Appointment of Countersigning Agent. (a) The Warrant Agent may appoint a Countersigning Agent or Agents which shall be authorized to act on behalf of the Warrant Agent to countersign Warrant Certificates issued upon original issue and upon exchange, registration of transfer or pursuant to Article 7, and Warrant Certificates so countersigned shall be entitled to the benefits of this Agreement equally and proportionately with any and all other Warrant Certificates duly executed and delivered hereunder. Wherever reference is made in this Agreement to the countersignature and delivery of Warrant Certificates by the Warrant Agent or to Warrant Certificates countersigned by the Warrant Agent, such reference shall be deemed to include countersignature and delivery on behalf of the Warrant Agent by a Countersigning Agent and Warrant Certificates countersigned by a Countersigning Agent. Each Countersigning Agent shall be acceptable to the Company and shall at the time of appointment be a corporation doing business under the laws of the United States of America or any State thereof in good standing, authorized under such laws to act as Countersigning Agent, and having a combined capital and surplus of not less than $50,000,000. The combined capital and surplus of any such new Countersigning Agent shall be deemed to be the combined capital and surplus as set forth in the most recent annual report of its condition published by such Countersigning Agent prior to its appointment, provided that such reports are published at least annually pursuant to law or to the requirements of a Federal or state supervising or examining authority.

(b) Any corporation into which a Countersigning Agent may be merged, or any corporation resulting from any consolidation to which such Countersigning Agent shall be a party, shall be a successor Countersigning Agent without any further act, provided that such corporation would be eligible for appointment as a new Countersigning Agent under the

provisions of Section 11.6(a), without the execution or filing of any paper or any further act on the part of the Warrant Agent or the Countersigning Agent. Any such successor Countersigning Agent shall promptly cause notice of its succession as Countersigning Agent to be given in accordance with Section 13.1(b) to each Holder of a Warrant Certificate at such Holder’s last address as shown on the Warrant Register.

(c) A Countersigning Agent may resign at any time by giving thirty (30) days’ prior written notice thereof to the Warrant Agent and to the Company. The Warrant Agent may at any time terminate the agency of a Countersigning Agent by giving thirty (30) days’ prior written notice thereof to such Countersigning Agent and to the Company.

(d) The Warrant Agent agrees to pay to each Countersigning Agent from time to time reasonable compensation for its services under this Section, and the Warrant Agent shall be entitled to be reimbursed for such payments, subject to the provisions of Section 11.3.

(e) Any Countersigning Agent shall have the same rights and immunities as those of the Warrant Agent set forth in Section 11.1.

Re: Xxxxxxxx Xxxxxxx, Inc. Warrants to Purchase Common Stock (the “Warrants”)

Reference is hereby made to the Warrant Agreement dated as of August 1, 2007 (the “Warrant Agreement”) between Xxxxxxxx Xxxxxxx, Inc. and Computershare Trust Company, N.A., as Warrant Agent. Capitalized terms used but not defined herein shall have the meanings given them in the Warrant Agreement.

This letter relates to Warrants exercisable for an aggregate of ___ Common Stock (“Warrant Shares”), which Warrants are held in the name of [name of transferor] (the “Transferor”) to effect the transfer of the Warrants to the undersigned.

In connection with such request, and in respect of such Warrants, we confirm that:

1. We understand that the Warrants and Warrant Shares have not been and may not be registered under the Securities Act, and are being sold to us in a transaction that is exempt from the registration requirements of the Securities Act.

2. We are a corporation, partnership or other entity or person having such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Warrants, and we are (or any account for which we are purchasing is) an Institutional Accredited Investor or a Qualified Institutional Buyer (as such terms are defined under the Securities Act), able to bear the economic risk of investment in the Warrants.

3. We are acquiring the Warrants for our own account (or for accounts as to which we exercise sole investment discretion and have authority to make, and do make, the statements contained in this letter) and not with a view to any distribution of the Warrants or Warrant Shares, subject, nevertheless, to the understanding that the disposition of our property shall at all times be and remain within our control.

4. We understand that (a) the Warrants will be delivered to us in registered form only and that the certificate delivered to us in respect of the Warrants will bear a legend substantially to the following effect:

B-1

[Restricted Warrant Legend]

THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AND IN THE CASE OF A TRANSACTION EXEMPT FROM REGISTRATION, UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO IT THAT SUCH TRANSACTION DOES NOT REQUIRE REGISTRATION UNDER THE SECURITIES ACT AND SUCH OTHER APPLICABLE LAWS.

and (b) such certificates shall be reissued without the foregoing legend only in the event of a disposition of the Warrants in accordance with the provisions of paragraph 5(c) or (d) below, or at our request at such times as we would be permitted to dispose of the Warrants in accordance with paragraph 5(d) below.

5. We agree that in the event that at some future time we wish to dispose of any of the Warrants or Warrant Shares, we will not do so unless:

(a) the Warrants or Warrant Shares are sold to the Company or any Subsidiary thereof;

(b) the Warrants are sold to an Institutional Accredited Investor or a Qualified Institutional Buyer, that, prior to such transfer, furnishes to the Warrant Agent a signed letter containing certain representations and agreements relating to the restrictions on transfer of the Warrants and Warrant Shares (the form of which letter can be obtained from the Warrant Agent);

(d) the Warrants or Warrant Shares are sold pursuant to an effective registration statement under the Securities Act.

Re: Xxxxxxxx Xxxxxxx, Inc. Warrants to Purchase Common Stock

Ladies and Gentlemen:

This opinion is being furnished to you in connection with the sale by ___ (the “Transferor”) to ___ (the “Purchaser”) of Warrants to Purchase Common Stock exercisable for an aggregate of ___ Common Stock, par value $.00000002 per share, of Xxxxxxxx Xxxxxxx, Inc. (the “Warrants”).

We have examined such documents and records as we have deemed appropriate. In our examination of the foregoing, we have assumed the authenticity of all documents, the genuineness of all signatures and the due authorization, execution and delivery of the aforementioned by each of the parties thereto. We have further assumed the accuracy of the representations contained in the Accredited Investor Transferee Certificate executed and delivered by the Purchaser in connection with its purchase of the Warrants made by the parties executing such document. We have also assumed that the sale of the Warrants to the Transferor was exempt from the registration and prospectus delivery requirements of the Securities Act of 1933, as amended (the “Securities Act”).

Based on the foregoing, we are of the opinion that the sale to the Purchaser of the Warrants is subject to a valid exemption from the registration requirements of the Securities Act and does not require registration of such Warrants or the Common Stock issuable upon exercise thereof under the Securities Act.

Very truly yours,

C-1
