(b) So long as a Global Warrant Certificate is registered in the name of the Depositary or its nominee, members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Agreement with respect to the Warrants evidenced by such Global Warrant Certificate held on their behalf by the Depositary or its custodian, and the Depositary may be treated by the Company, the Warrant Agent and any agent of the Company or the Warrant Agent as the absolute owner of such Warrants, and as the sole Holder of such Warrant Certificate, for all purposes.

(d) Transfers of a Global Warrant Certificate registered in the name of the Depositary or its nominee shall be limited to transfers in whole, and not in part, to the Depositary, its successors, and their respective nominees except as set forth inSection 2.4(e). Interests of beneficial owners in a Global Warrant Certificate registered in the name of the Depositary or its nominee shall be transferred in accordance with the Applicable Procedures of the Depositary.

Any Definitive Warrant Certificate delivered in exchange for an interest in a Global Warrant Certificate pursuant to thisSection 2.4(e) shall not bear the Global Warrant Legend. Interests in any Global Warrant Certificate may not be exchanged for Definitive Warrant Certificates other than as provided in thisSection 2.4(e).

(f) The holder of a Global Warrant Certificate registered in the name of the Depositary or its nominee may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder of a Warrant Certificate is entitled to take under this Agreement or such Global Warrant Certificate.

(g) Each Global Warrant Certificate will evidence such of the outstanding Warrants as will be specified therein and each shall provide that it evidences the aggregate number of outstanding Warrants from time to time endorsed thereon and that the aggregate number of outstanding Warrants evidenced thereby may from time to time be reduced, to reflect exercises or expirations. Any endorsement of a Global Warrant Certificate to reflect the amount of any decrease in the aggregate number of outstanding Warrants evidenced thereby will be made by the Warrant Agent (i) in the case of an exercise, in accordance with the Applicable Procedures as required bySection 3.2(d) or (ii) in the case of an expiration, in accordance withSection 3.2(c).

(h) The Company initially appoints DTC to act as Depositary with respect to the Global Warrant Certificates.

(i) Every Warrant Certificate authenticated and delivered in exchange for, or in lieu of, a Global Warrant Certificate or any portion thereof, pursuant to thisSection 2.4 orSection 6 orSection 8, shall be authenticated and delivered in the form of, and shall be, a Global Warrant Certificate, and a Global Warrant Certificate may not be exchanged for a Definitive Warrant Certificate, in each case, other than as provided inSection 2.4(e). Whenever any provision herein refers to issuance by the Company and countersignature and delivery by the Warrant Agent of a new Warrant Certificate in exchange for the portion of a surrendered Warrant Certificate that has not been exercised, in lieu of the surrender of any Global Warrant Certificate and the issuance, countersignature and delivery of a new Global Warrant Certificate in exchange therefor, the Warrant Agent, on the Company’s written instruction, may endorse such Global Warrant Certificate to reflect a reduction in the number of Warrants evidenced thereby in the amount of Warrants so evidenced that have been so exercised.

(j) Beneficial interests in any Global Warrant Certificate may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Global Warrant Certificate in accordance with the Applicable Procedures.

(k) At such time as all Warrants evidenced by a particular Global Warrant Certificate have been exercised or expired in whole and not in part, such Global Warrant Certificate shall, if not in custody of the Warrant Agent, be surrendered to or retained by the Warrant Agent for cancellation in accordance withSection 3.5.

3.	Exercise and Expiration of Warrants.

The Exercise Price, and the number of Common Shares obtainable upon exercise of each Warrant, shall be adjusted from time to time as required bySection 5.1.

3.2Exercise and Expiration of Warrants.

(a)Exercise of Warrants. Subject to and upon compliance with the terms and conditions set forth herein, includingSection 3.2(b), 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 the Original Issue Date until 5:00 p.m., New York time, on the Expiration Date, for the Common Shares obtainable thereunder.

(b)Condition to Exercise of Warrants.

For the avoidance of doubt, the Warrants shall be exercisable from and after any Trading Day on which the Current Market Price of the Common Shares has equaled or exceeded $2.50 per share (subject to adjustment in the same manner as the Exercise Price), regardless of the Current Market Price of the Common Shares on the applicable Exercise Date.

The Company, whenever required by the Warrant Agent, will supply the Warrant Agent with Definitive Warrant Certificates duly executed on behalf of the Company for such purpose.

(f)Issuance of Common Shares. Upon due exercise of Warrants evidenced by any Warrant Certificate in conformity with the foregoing provisions ofSection 3.2(d), the Warrant Agent shall, when actions specified inSection 3.2(d)(i) have been effected and any payment specified inSection 3.2(d)(ii) is received, deliver to the Company the Exercise Form received pursuant toSection 3.2(d)(i), deliver or deposit all funds, in accordance withSection 3.3, received as instructed in writing by the Company and advise the Company by telephone promptly thereafter of the amount of funds so deposited to its account.

The Common Shares in book-entry form or certificate or certificates representing Common Shares so delivered shall be, to the extent possible, in such denomination or denominations as such Holder shall request in the applicable Exercise Form and shall be registered or otherwise placed in the name of, and delivered to, the Holder or, subject toSection 3.4, such other Person as shall be designated by the Holder in such Exercise Form (the Holder or such other Person being referred to herein as the “Recipient”). If the Company has a stockholder rights plan in effect upon exercise of the Warrants, each Common Share issued upon such exercise shall be entitled to receive the appropriate number of rights, if any, and any certificates representing the Common Shares issued upon such exercise shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time.

(g)Time of Exercise. Each exercise of a Warrant shall be deemed to have been effected immediately prior to the close of business on the day on which each of the requirements for exercise of such Warrant specified inSection 3.2(d) has been duly satisfied (the “ExerciseDate”). At such time, subject toSection 5.1(f)(iv), Common Shares in book-entry form or the certificates for the Common Shares issuable upon such exercise as provided inSection 3.2(f) 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 Common Shares.

3.3Application of Funds upon Exercise of Warrants. All funds received by Computershare under this Agreement that are to be distributed or applied by Computershare in the performance of the services hereunder (the “Funds”) shall be held by Computershare as agent for the Company and deposited in one or more bank accounts to be maintained by Computershare in its name as agent for the Company. Until paid pursuant to the terms of this Agreement, Computershare will hold the Funds through such accounts in: deposit accounts of commercial banks with Tier 1 capital exceeding $1 billion or with an average rating above investment grade by S&P (LT Local Issuer Credit Rating), Moody’s (Long Term Rating) and Fitch Ratings, Inc. (LT Issuer Default Rating) (each as reported by Bloomberg Finance L.P.). Computershare shall have no responsibility or liability for any diminution of the Funds that may result from any deposit made by Computershare in accordance with this Agreement, including any losses resulting from a default by any bank, financial institution or other third party. Computershare may from time to time receive interest, dividends or other earnings in connection with such deposits. Computershare shall not be obligated to pay such interest, dividends or earnings to the Company, any holder or any other party. The Warrant Agent shall forward funds received for warrant exercises in a given month by the fifth Business Day of the following month by wire transfer to an account designated by the Company.

3.4Payment of Taxes. The Company shall pay any and all documentary, issuance, registration, stamp and similar taxes that may be payable in respect of the issue or delivery of Common Shares on exercise of Warrants pursuant hereto. The Company or the Warrant Agent shall not be required, however, to pay any tax or other charge imposed in respect of any transfer involved in the issue and delivery of Common Shares in book-entry form or any certificates for Common Shares or payment of cash or other property to any Recipient other than the Holder of the Warrant Certificate evidencing the exercised Warrant, and in case of such transfer or payment, the Warrant Agent and the Company shall not be required to issue or deliver any Common Shares in book-entry form or any certificate or 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 and the Warrant Agent’s satisfaction that any such tax or other charge that is or may become due has been paid.

3.5Cancellation of Warrant Certificates. Any Definitive Warrant Certificate surrendered for exercise shall, if surrendered to the Company, be delivered to the Warrant Agent. All Warrant Certificates surrendered or delivered to or received by the Warrant Agent for cancellation pursuant to thisSection 3.5 orSection 2.4(e) orSection 2.4(k) shall be promptly cancelled by the Warrant Agent and shall not be reissued by the Company. The Warrant Agent shall destroy any such cancelled Warrant Certificates and deliver its certificate of destruction to the Company, unless the Company shall otherwise direct in writing.

3.6Shares Issuable. The number of Common Shares “obtainable upon exercise” of Warrants at any time shall be the number of Common Shares into which such Warrants are then exercisable. The Company will confirm the number of shares issuable if so requested by the Warrant Agent. The number of Common Shares “into which each Warrant is exercisable” shall be one share, subject to adjustment as provided inSection 5.1.

3.7Cashless Exercise. Notwithstanding any provisions herein to the contrary, if, on the Exercise Date of a Cashless Exercise, the Cashless Exercise Current Market Price of one Common Share is greater than the applicable Exercise Price on the Exercise Date, then, in lieu of paying to the Company the applicable Exercise Price by wire transfer in immediately available funds, the Holder may elect to receive Common Shares equal to the value (as determined below) of the Warrants or any portion thereof being exercised (such portion, the “Cashless Exercise Warrants” with respect to such date) by (i) in the case of Warrants evidenced by a Global Warrant Certificate, providing written notice to the Warrant Agent pursuant to the Applicable Procedures; or (ii) in the case of Warrants evidenced by a Definitive Warrant Certificate, providing notice pursuant to the Exercise Form, in the case of (i) or (ii), that the Holder desires to effect a “cashless exercise” (a “Cashless Exercise”) with respect to the Cashless Exercise Warrants, in which event the Company shall issue to the Holder a number of Common Shares with respect to Cashless Exercise Warrants computed using the following formula (it being understood that any portion of the Warrants being exercised on such date that are not Cashless Exercise Warrants will not be affected by this calculation):


		X = (Y ×(A-B)) ÷ A

WhereX =		the number of Common Shares to be issued to the Holder in respect of the Cashless Exercise Warrants

Y =		the number of Common Shares purchasable under the Cashless Exercise Warrants being exercised by the Holder (on the Exercise Date)

A =		the applicable Cashless Exercise Current Market Price of one Common Share (on the Exercise Date)

B =		the applicable Exercise Price (as adjusted through and including the Exercise Date).

The Company shall calculate and transmit to the Warrant Agent the number of Common Shares to be issued on such Cashless Exercise, and the Warrant Agent shall have no obligation under this Agreement to calculate, confirm or verify such amount.

3.8Cost Basis Information.

(a) In the event of a cash exercise, the Company hereby instructs the Warrant Agent to record cost basis for newly issued shares at the time of such exercise in accordance with written instructions by the Company. If the Company does not provide such cost basis information to the Warrant Agent, as outlined above, then the Warrant Agent will treat those shares issued hereunder as uncovered securities or the equivalent, and each holder of such shares must obtain such cost basis information from the Company.

(b) In the event of a Cashless Exercise, the Company shall provide cost basis for shares issued pursuant to a Cashless Exercise at the time the Company provides the shares issued pursuant to such Cashless Exercise to the Warrant Agent pursuant to Section 3.7 hereof.

4.	Dissolution, Liquidation or Winding up.

UnlessSection 5.1(h) applies, 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 (a “Winding Up”) of the affairs of the Company, the Company shall give written notice thereof to the Warrant Agent and all Holders in the manner provided inSection 11.1(b) 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 Shares shall be entitled to exchange their shares for securities, money 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 receive the securities, money or other property which such Holder would have been entitled to receive had such Holder been the holder of record of the Common Shares into which the Warrants were exercisable immediately prior to such dissolution, liquidation or winding up (net of thethen-applicable Exercise Price) and the rights to exercise the Warrants shall terminate.

UnlessSection 5.1(h) applies, 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 funds or other property which the Holders are entitled to receive pursuant to the above paragraph, together with a Company Order as to the distribution thereof. After receipt of such deposit from the Company and after receipt of surrendered Warrant Certificates evidencing Warrants, and any such other necessary information as the Warrant Agent may reasonably require (including, but not limited to, signature guarantees), the Warrant Agent shall make payment in 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 thisSection 4 except such as it shall agree in writing with the Company to pay thereon. Any moneys, securities or other property which at any time shall be deposited by the Company or on its behalf with the Warrant Agent pursuant to thisSection 4 shall be, and are hereby, assigned, transferred and set over to the Warrant Agent in accordance withSection 3.3 hereof;provided,that, moneys, securities or other property need not be segregated from other funds, securities or other property held by the Warrant Agent except to the extent required by law.

5.	Adjustments.

5.1Adjustments. In order to prevent dilution of the rights granted under the Warrants and to grant the Holders certain additional rights, the Exercise Price shall be subject to adjustment from time to time only as specifically provided in thisSection 5.1 (the “Adjustment Events”) and the number of Common Shares obtainable upon exercise of Warrants shall be subject to adjustment from time to time only as specifically provided in thisSection 5.1.

(a)Subdivisions and Combinations. In the event the Company shall, at any time or from time to time after the Original Issue Date while any Warrants remain outstanding and unexpired in whole or in part, effect a subdivision (by any stock split or otherwise) of the outstanding Common Shares into a greater number of Common Shares (other than (x) a subdivision upon a Transaction to whichSection 5.1(h) applies or (y) a stock split effected by means of a stock dividend or distribution to whichSection 5.1(b) applies), then and in each such event the Exercise Price in effect at the opening of business on the date upon which such subdivision becomes effective shall be proportionately decreased. Conversely, if the Company shall, at any time or from time to time after the Original Issue Date while any Warrants remain outstanding and unexpired in whole or in part, effect a combination (by any reverse stock split or otherwise) of the outstanding Common Shares into a smaller number of Common Shares (other than a combination upon a Transaction to whichSection 5.1(h) applies), then and in each such event the Exercise Price in effect at the opening of business on the date upon which such combination becomes effective shall be proportionately increased. Any adjustment under thisSection 5.1(a) shall become effective immediately after the opening of business on the date upon which the subdivision or combination becomes effective (or, if the subdivision or combination does not become effective until after the opening of business on such date, the adjustment under thisSection 5.1(a) shall become effective immediately after the effectiveness of such subdivision or combination).

(b)Common Share Dividends. In the event the Company shall, at any time or from time to time after the Original Issue Date while any Warrants remain outstanding and unexpired in whole or in part, make or issue to the holders of its Common Shares a dividend or distribution payable in, or otherwise make or issue a dividend or other distribution on any class of its capital stock payable in, Common Shares (other than a dividend or distribution upon a Transaction to whichSection 5.1(h) applies), then and in each such event the Exercise Price in effect immediately prior to the close of business on the date for the determination of the holders of Common Shares entitled to receive such dividend or distribution shall be decreased by multiplying such Exercise Price by a fraction (not to be greater than 1):

(i) the numerator of which shall be the total number of Common Shares issued and outstanding at the close of business on such date for determination; and

(ii) the denominator of which shall be the total number of Common Shares issued and outstanding at the close of business on such date for determination plus the number of Common Shares issuable in payment of such dividend or distribution.

Any adjustment under thisSection 5.1(b) shall, subject toSection 5.1(f)(iv), become effective immediately prior to the opening of business on the day after the date for the determination of the holders of Common Shares entitled to receive such dividend or distribution.

(c)Reclassifications. A reclassification of the Common Shares (other than any such reclassification in connection with a merger or consolidation or sale to whichSection 5.1(h) applies) into Common Shares and shares of any other class of stock shall be deemed:

(i) a Specified Dividend by the Company to the holders of its Common Shares of such shares of such other class of stock for the purposes and within the meaning ofSection 5.1(d) (and the effective date of such reclassification shall be deemed to be “the date for the determination of the holders of Common Shares entitled to receive such dividend or distribution” for the purposes and within the meaning ofSection 5.1(d)); and

(ii) if the outstanding Common Shares shall be changed into a larger or smaller number of Common Shares as a part of such reclassification, such change shall be deemed a subdivision or combination, as the case may be, of the outstanding Common Shares for the purposes and within the meaning ofSection 5.1(a) (and the effective date of such reclassification shall be deemed to be “the date upon which such subdivision becomes effective” or “the date upon which such combination becomes effective,” as applicable, for the purposes and within the meaning ofSection 5.1(a)).

(d)Specified Dividends. In the event the Company shall, at any time or from time to time after the Original Issue Date while any Warrants remain outstanding and unexpired in whole or in part, make or issue any dividend of cash or other distribution of cash and/or property (including rights, options or warrants), whether in aspin-off transaction or otherwise, to all holders of its Common Shares (other than any dividend or distribution (i) upon a Transaction to whichSection 5.1(h) applies or (ii) to which Section 5.1(b) applies) (a “Specified Dividend”), then and in each such event, the Exercise Price in effect immediately prior to the close of business on the date for the determination of the holders of Common Shares entitled to receive such dividend or distribution shall be decreased by multiplying such Exercise Price by a fraction (not to be greater than 1):

(i) the numerator of which shall be (x) the Quoted Price on the Trading Day immediately preceding theEx-Dividend Date for such dividend or distributionminus (y) the amount of any cash and the fair market value of anynon-cash property as of theEx-Dividend Date for such dividend or distribution (as determined by the Board of Directors in good faith and in a commercially reasonable manner) to be distributed with respect to each Common Share; and

(ii) the denominator of which shall be the Quoted Price on the Trading Day immediately preceding theEx-Dividend Date for such dividend or distribution.

Any adjustment under thisSection 5.1(d) shall, subject toSection 5.1(f)(iv), become effective immediately prior to the opening of business on the day after the date for the determination of the holders of Common Shares entitled to receive such Specified Dividend.

Rights or warrants issued by the Company to all holders of the Common Shares entitling the holders thereof to subscribe for or purchase Common Shares, which rights or warrants (A) are deemed to be transferred with such Common Shares, (B) are not exercisable and (C) are also issued in respect of future issuances of Common Shares, in each case in clauses (A) through (C) until the occurrence of a specified event or events (“Trigger Event”), shall not give rise to an adjustment pursuant to thisSection 5.1(d) until the occurrence of the earliest Trigger Event.

(e)Tender and Exchange Offers. If the Company or any of its Subsidiaries makes a payment in respect of a tender or exchange offer for the Common Shares, to the extent that the cash and value of any other consideration (as determined by the Board of Directors of the Company acting in good faith and in a commercially reasonable manner) included in the payment

per share of the Common Shares exceeds the Quoted Price on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Exercise Price in effect immediately prior to the close of business on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer shall be decreased by multiplying such Exercise Price by a fraction (not to be greater than 1):

(i) the numerator of which shall be the product of (x) the number of Common Shares outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all Common Shares accepted for purchase or exchange in such tender or exchange offer) and (y) the Quoted Price on the Trading Day next succeeding the date such tender or exchange offer expires; and

(ii) the denominator of which shall be the sum of (x) aggregate value of all cash and any other consideration (as determined by the Board of Directors of the Company in good faith and in a commercially reasonable manner) paid or payable for Common Shares purchased in such tender or exchange offer and (y) the product of (A) the Quoted Price on the Trading Day next succeeding the date such tender or exchange offer expires and (B) the number of Common Shares outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all Common Shares accepted for purchase or exchange in such tender or exchange offer).

Any adjustment under thisSection 5.1(e) shall, subject toSection 5.1(f)(iv), become effective immediately prior to the opening of business on the day after the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer.

(f)Other Provisions Applicable to Adjustments. The following provisions shall be applicable to the making of adjustments to the Exercise Price and the number of Common Shares into which each Warrant is exercisable underSection 5.1:

(i)Treasury Stock. The dividend or distribution of any issued Common Shares owned or held by or for the account of the Company shall be deemed a dividend or distribution of Common Shares for purposes ofSection 5.1(b). The Company shall not make or issue any dividend or distribution on Common Shares held in the treasury of the Company. For the purposes ofSection 5.1(b), the number of Common Shares at any time outstanding shall not include shares held in the treasury of the Company.

(ii)When Adjustments Are to be Made. The adjustments required bySection 5.1(a),Section 5.1(b),Section 5.1(c),Section 5.1(d) andSection 5.1(e) shall be made whenever and as often as any specified event requiring an adjustment shall occur, except that no adjustment of the Exercise Price that would otherwise be required shall be made unless and until such adjustment either by itself or with other adjustments not previously made increases or decreases the Exercise Price immediately prior to the making of such adjustment by at least 1%. Any adjustment representing a change of less than such minimum amount (except as aforesaid) shall be carried forward and made as soon as such adjustment, together with other adjustments required bySection 5.1(a),Section 5.1(b),Section 5.1(c),Section 5.1(d) andSection 5.1(e) and not previously made, would result in such minimum adjustment and, in any case, shall be made on any Exercise Date.

(iii)Fractional Interests. In computing adjustments underSection 5.1, fractional interests in Common Shares shall be taken into account to the nearestone-thousandth of a share.

(iv)Deferral of Issuance Upon Exercise. In any case in whichSection 5.1(b),Section 5.1(d) orSection 5.1(e) shall require that a decrease in the Exercise Price be made effective prior to the occurrence of a specified event and any Warrant is exercised after the time at which the adjustment became effective but prior to the occurrence of such specified event and, in connection therewith,Section 5.1(g) shall require a corresponding increase in the number of Common Shares into which each Warrant is exercisable, the Company may elect to defer, with written notice to the Warrant Agent (but not in any event later than the Expiration Date) until the occurrence of such specified event (A) the issuance to the Holder of the Warrant Certificate evidencing such Warrant (or other Person entitled thereto) of, and the registration of such Holder (or other Person) as the record holder of, the Common Shares over and above the Common Shares issuable upon such exercise on the basis of the number of Common Shares obtainable upon exercise of such Warrant immediately prior to such adjustment and to require payment in respect of such number of shares the issuance of which is not deferred on the basis of the Exercise Price in effect immediately prior to such adjustment and (B) the corresponding reduction in the Exercise Price;provided,however, that the Company shall deliver to such Holder or other person a due bill or other appropriate instrument that meet any applicable requirements of the principal national securities exchange or other market on which the Common Shares are then traded and evidences the right of such Holder or other Person to receive, and to become the record holder of, such additional Common Shares, upon the occurrence of such specified event requiring such adjustment (without payment of any additional Exercise Price in respect of such additional shares).

(v)Adjustment of Prices. Whenever any provision of this Warrant Agreement requires the calculation of the Quoted Price over a span of multiple days (including, without limitation, for purposes of determining the Current Market Price), the Board of Directors shall make appropriate adjustments thereto to account for any adjustment to the Exercise Price that becomes effective, or any event requiring an adjustment to the Exercise Price where the record date, effective date orEx-Dividend Date, as the case may be, of the event occurs, at any time during the period when the Quoted Price is to be calculated.

(vi)Valuation Determinations.

(A) If the Required Warrant Holders object to any determination by the Board of Directors of the Company of (I) the fair market value of anynon-cash property distributed on the Common Shares pursuant toSection 5.1(d), (II) the value of anynon-cash consideration payable in a tender or exchange offer pursuant toSection 5.1(e), (III) the Current Market Price pursuant to clause (ii) of the definition thereof or (IV) the value of a unit of Reference Property pursuant toSection 5.1(h)(i)(A), the Required Warrant Holders shall have the right to deliver a

written notice to the Company within 10 days after the Company delivers written notice to Holders pursuant toSection 11.2 of such determination requesting that an Independent Financial Expert calculate such value as of the date of determination referred to in the applicable provision.

(B) No later than two Business Days after receiving notice from the Required Warrant Holders pursuant toSection 5.1(f)(vi)(A) above, the Company shall provide notice to the Holders of an Independent Financial Expert selected by the Company (the “Company Selected Expert”) to make the related valuation determination (the date on which such notice is delivered, the “Notice Date”). In the event that the Required Warrant Holders object in writing to the Company Selected Expert within seven days of the Notice Date, then the Company and Required Warrant Holders shall jointly select an Independent Financial Expert by no later than the 17th day after the Notice Date. If the Company and the Required Warrant Holders are unable to agree on a jointly selected Independent Financial Expert, the Required Warrant Holders shall select promptly, but no later than the 17th day after the Notice Date, a separate Independent Financial Expert and such Independent Financial Expert and the Company Selected Expert shall select promptly, but no later than the 19th day after the Notice Date, a third Independent Financial Expert to make the relevant valuation determination. The determination of the finally selected Independent Financial Expert shall be final and conclusive, and the fees and expenses of any such Independent Financial Experts shall be borne by the Company. The relevant determination shall be completed no later than the date that is 30 days after the date the Company receives notice from the Required Warrant Holders pursuant toSection 5.1(f)(vi)(A) above.

(C) Within two Business Days after completion of the determination of the Independent Financial Expert pursuant toSection 5.1(f)(vi)(B) above, the Company shall cause the complete written report of the Independent Financial Expert as to such determination to be delivered to the Holders.

(g)Adjustment to Shares Obtainable Upon Exercise. Whenever the Exercise Price is adjusted as provided inSection 5.1(a),(b),(c),(d) or(e), the number of Common Shares into which a Warrant is exercisable shall simultaneously be adjusted by multiplying such number of Common Shares into which a Warrant is exercisable immediately prior to such adjustment by a fraction, the numerator of which shall be the Exercise Price immediately prior to such adjustment, and the denominator of which shall be the Exercise Price immediately thereafter.

(h)Changes in Common Shares. In case at any time or from time to time after the Original Issue Date while any Warrants remain outstanding and unexpired in whole or in part, the Company shall be a party to or shall otherwise engage in any transaction or series of related transactions constituting: (1) a merger of the Company into, a direct or indirect sale of all of the Company’s equity to, a consolidation, amalgamation or similar transaction of the Company with, or a sale of all or substantially all of the assets of the Company and its Subsidiaries (taken as a whole) to, any other Person in which the previously outstanding Common Shares shall be (either directly or upon subsequent liquidation) cancelled, reclassified or converted or changed into or exchanged for securities or other property (including cash) or any combination of the foregoing,

or (2) any merger of another Person into the Company or any recapitalization, reclassification or change of the Common Shares, in each case, in which the previously outstanding Common Shares shall be cancelled, reclassified or converted or changed into or exchanged for securities of the Company or other property (including cash) of the Company or another Person or any combination of the foregoing (any such transaction or series of related transactions in clauses (1) or (2), a “Transaction”) then:

(i) in the case of any Transaction other than a Cash Transaction, as a condition to the consummation of such Transaction, the Company shall or shall cause such other Person, as the case may be, to execute and deliver to the Warrant Agent a written instrument providing that:

(A) so long as any Warrant remains outstanding in whole or in part (including after giving effect to the changes specified underclause (B) below), such Warrant, upon the exercise thereof at any time on or after the consummation of such Transaction, shall be exercisable (on such terms and subject to such conditions as shall be as nearly equivalent as may be practicable to the provisions set forth in this Agreement) into, in lieu of the Common Shares issuable upon such exercise prior to such consummation, the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that would have been receivable upon such Transaction by a holder of the number of Common Shares into which such Warrant was exercisable immediately prior to such Transaction (“Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one Common Share is entitled to receive);provided that (I) if the Transaction causes the Common Shares to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then the Reference Property shall be deemed to be the weighted average of the types and amounts of consideration actually received by the holders of Common Shares and (II) the Quoted Price and Current Market Price shall be calculated based on the value of a unit of Reference Property, as determined by the Board of Directors of the Company acting in good faith and in a commercially reasonable manner; and

(B) the rights and obligations of such other Person and the Holders in respect of Reference Property shall be substantially unchanged to be as nearly equivalent as may be practicable to the rights and obligations of the Company and Holders in respect of Common Shares hereunder as set forth inSection 3.1 hereof;

(ii) with respect to any Transaction other than a Cash Transaction, such written instrument under clause (i) above shall provide for adjustments which, for events subsequent to the effective date of such written instrument shall be as nearly equivalent as may be practicable to the adjustments provided for in thisSection 5. The above provisions of thisSection 5.1(h) shall similarly apply to successive Transactions; or

(iii) if such Transaction is a Cash Transaction, then, at the effective time of the consummation of such Cash Transaction any Warrants not exercised prior to the closing of such Cash Transaction shall automatically terminate and become void and shall be cancelled for no further consideration.

(i)Compliance with Governmental Requirements. The Company will take any corporate action that may be necessary in order that the Company may validly and legally issue fully paid andnon-assessable Common Shares at any applicable adjusted Exercise Price.

(j)Optional Tax Adjustment. The Company may at its option, at any time during the term of the Warrants, increase the number of Common Shares into which each Warrant is exercisable, or decrease the Exercise Price, in addition to those changes required bySection 5.1(a),Section 5.1(b),Section 5.1(c),Section 5.1(d) andSection 5.1(e) as deemed advisable by the Board of Directors of the Company, in order that any event treated for Federal income tax purposes as a dividend of stock or stock rights shall not be taxable to the recipients of such dividend of stock or stock rights.

(k)Warrants Deemed Exercisable. For purposes solely of thisSection 5, the number of Common Shares which the holder of any Warrant would have been entitled to receive had such Warrant been exercised in full at any time or into which any Warrant was exercisable at any time shall be determined assuming such Warrant was exercisable in full at such time.

(l)Notice of Adjustment. Upon the occurrence of each adjustment of the Exercise Price or the number of Common Shares into which a Warrant is exercisable pursuant to thisSection 5.1, the Company at its expense shall promptly:

(i) compute such adjustment in accordance with the terms hereof;

(ii) after such adjustment becomes effective, deliver to all Holders, in accordance withSection 11.1(b) andSection 11.2 (including by means of a current report on Form8-K), a notice setting forth such adjustment and showing in detail the facts upon which such adjustment is based; and

(iii) deliver to the Warrant Agent a certificate of the Chief Financial Officer of the Company setting forth the Exercise Price and the number of Common Shares into which each Warrant is exercisable after such adjustment and setting forth a brief, reasonably detailed statement of the facts requiring such adjustment and the computation by which such adjustment was made (including a description of the basis on which the Current Market Price of the Common Shares was determined). As provided inSection 10, the Warrant Agent shall be entitled to rely on and shall be fully protected in relying on such certificate and on any adjustment or statement therein contained and shall be under no duty or responsibility with respect to any such certificate, except to exhibit the same from time to time to any Holder desiring an inspection thereof during reasonable business hours. The Company hereby agrees that it will provide the Warrant Agent with reasonable written notice of any Adjustment Event set forth in this Section 5.1. The Company further agrees that it will provide to the Warrant Agent any new or amended exercise terms. The Warrant Agent shall have no obligation under any Section of this Agreement to determine whether an Adjustment Event has occurred or to calculate any of the adjustments set forth herein.

(m)Statement on Warrant Certificates. Irrespective of any adjustment in the Exercise Price or amount or kind of shares into which the Warrants are exercisable, Warrant Certificates theretofore or thereafter issued may continue to express the same Exercise Price initially applicable or amount or kind of shares initially issuable upon exercise of the Warrants evidenced thereby pursuant to this Agreement.

5.2Fractional Interest. The Company shall not be required upon the exercise of any Warrant (including, without limitation, underSection 3.7) to issue any fractional Common Shares, but may, in lieu of issuing any fractional Common Shares make an adjustment therefore in cash on the basis of the Current Market Price per Common Share on the date of such exercise. If Warrant Certificates evidencing more than one Warrant shall be presented for exercise at the same time by the same Holder, the number of full Common Shares which shall be issuable upon such exercise thereof shall be computed on the basis of the aggregate number of Warrants so to be exercised. The Holders, by their acceptance of the Warrant Certificates, expressly waive their right to receive any fraction of a Common Share or a stock certificate representing a fraction of a Common Share if such amount of cash is paid in lieu thereof. If the Company shall decide that cash will be provided instead of fractional shares, then the Company shall inform the Warrant Agent of the amount to be paid upon the fractional exercise of the Warrant. Further, if the Company shall decide that cash will be provided instead of fractional shares, then the Company shall provide an initial funding of two thousand dollars ($2000) for the purpose of issuing cash in lieu of fractional shares. From time to time thereafter, Computershare may request additional funding to cover fractional payments. Computershare shall have no obligation to make fractional payments unless the Company shall have provided the necessary funds to pay in full all amounts due and payable with respect thereto.

5.3No Other Adjustments. Except in accordance withSection 5.1, the applicable Exercise Price and the number of Common Shares obtainable upon exercise of any Warrant will not be adjusted for the issuance of Common Shares or any securities convertible into or exchangeable for Common Shares or carrying the right to purchase any of the foregoing, including, without limitation

(i) upon the issuance of any other securities by the Company on or after the Original Issue Date, or upon the issuance of Common Shares upon the exercise of any such securities;

(ii) upon the issuance of any Common Shares or other securities or any payments pursuant to any management or other equity incentive plan of the Company;

(iii) upon the issuance of any Common Shares pursuant to the exercise of the Warrants; or

(iv) upon the issuance of any Common Shares or other securities of the Company in connection with a business acquisition transaction.

6.	Loss or Mutilation.

If (a) any mutilated Warrant Certificate is surrendered to the Warrant Agent or (b) both (i) there shall be delivered to the Company and the Warrant Agent (A) a claim by a Holder as to the destruction, loss or wrongful taking of any Warrant Certificate of such Holder and a request thereby for a new replacement Warrant Certificate, and (B) such open penalty surety bond and/or indemnity bond as may be required by them to save each of them and any agent of either of them harmless and (ii) such other reasonable requirements as may be imposed by the Company or Warrant Agent as permitted bySection 8-405 of the Uniform Commercial Code have been satisfied, then, in the absence of notice to the Company or the Warrant Agent that such Warrant Certificate has been acquired by a “protected purchaser” within the meaning of Section 8-405 of the Uniform Commercial Code or 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, wrongfully taken, destroyed or mutilated Warrant Certificate, in exchange therefore 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 ofSection 3.2(d)(i)(y)(II) to have been surrendered for exercise on the date the conditions specified in clauses (A) or (B) of the preceding sentence were first satisfied. The Warrant Agent may, at its option, issue replacement Warrants for mutilated certificates upon presentation thereof without such indemnity.

Upon the issuance of any new Warrant Certificate under thisSection 6, the Company or the Warrant Agent 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. The Warrant Agent has no duty or obligation to issue a new Warrant Certificate unless it is satisfied that such tax or charge has been paid.

Every new Warrant Certificate executed and delivered pursuant to thisSection 6 in lieu of any lost, wrongfully taken or destroyed Warrant Certificate shall constitute an additional contractual obligation of the Company, whether or not the allegedly lost, wrongfully taken 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 thisSection 6 are exclusive and shall preclude (to the extent lawful) all other rights or remedies with respect to the replacement of mutilated, lost, wrongfully taken, or destroyed Warrant Certificates.

7.	Reservation and Authorization of Common Shares.

The Company covenants that, for the duration of the Exercise Period, the Company will at all times reserve and keep available, from its authorized and unissued Common Shares solely for issuance and delivery upon the exercise of the Warrants and free of preemptive rights, such number of Common Shares and other securities, cash or property as from time to time shall be issuable upon the exercise in full of all outstanding Warrants for cash. The Company further covenants that it shall, from time to time, take all steps necessary to increase the authorized number of Common Shares if at any time the authorized number of Common Shares remaining unissued would otherwise be insufficient to allow delivery of all the Common Shares then deliverable upon the exercise in full of all outstanding Warrants. The Company covenants that all Common Shares

issuable upon exercise of the Warrants will, upon issuance, be duly and validly issued, fully paid and nonassessable and will be free of restrictions on transfer and will be free from all liens and charges in respect of the issue thereof. The Company shall take all such actions as may be necessary to ensure that all such Common Shares may be so issued without violation of any applicable law or governmental regulation or any requirements of any U.S. national securities exchange upon which Common Shares may be listed (except for official notice of issuance which shall be immediately delivered by the Company upon each such issuance). The Company covenants that all Common 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 Shares are then listed. The Company covenants that the stock certificates issued to evidence any Common Shares issued upon exercise of Warrants, if any, will comply with the Yukon Business Corporations Act and any other applicable law.

The Company hereby authorizes and directs its current and future transfer agents for the Common Shares at all times to reserve stock certificates for such number of authorized shares, to the extent as, and if, required. The Company will supply such transfer agents with duly executed stock certificates for such purposes, to the extent as, and if, required.

8.	Warrant Transfer Books.

The Warrant Certificates evidencing the Warrants shall be issued in registered form only. The Company shall cause to be kept at the office or offices 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.

Upon surrender for registration of transfer of any Warrant Certificate at the office of the Warrant Agent designated for such purpose, 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.

At the option of the Holder, Warrant Certificates may be exchanged at the office or offices of the Warrant Agent upon payment of the charges hereinafter provided for other Warrant Certificates evidencing a like aggregate number of Warrants. 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.

Every Warrant Certificate surrendered for registration of transfer or exchange shall (if so required by the Company or the Warrant Agent) be: (i) duly endorsed and containing a signature guarantee from an eligible guarantor institution participating in a signature guarantee program approved by the Securities Transfer Association, or (ii) 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, also containing a signature guarantee from an eligible guarantor institution participating in a signature guarantee program approved by the Securities Transfer Association. Further, to effect such transfer or exchange, all other necessary information or documentation shall be provided as the Warrant Agent may reasonably request.

No service charge shall be made for any registration of transfer or exchange of Warrant Certificates;provided,however, the Company or the Warrant Agent may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Warrant Certificates.

The Warrant Agent shall, upon the reasonable 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 Common Shares as the Company may reasonably request. The Warrant Agent shall, upon reasonable advance notice, also make available to the Company for inspection by the Company’s agents or employees (at the Company’s sole cost and expense), from time to time as the Company may reasonably 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 office of the Warrant Agent designated for such purpose during normal business hours.

The Warrant Agent shall keep copies of this Agreement and any notices given to Holders hereunder available for inspection, upon reasonable advance notice, by the Holders during normal business hours at the office of the Warrant Agent designated for such purpose. 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.

9.	Warrant Holders.

9.1No Voting or Dividend Rights.

(a) No Holder of a Warrant Certificate evidencing any Warrant shall have or exercise any rights by virtue hereof as a holder of Common Shares of the Company, including, without limitation, the right to vote, to receive dividends and other distributions as a holder of Common Shares or to receive notice of, or attend, meetings or any other proceedings of the holders of Common Shares.

(b) The consent of any Holder of a Warrant Certificate shall not be required with respect to any action or proceeding of the Company.

(d) No Holder of a Warrant Certificate shall have any right not expressly conferred hereunder or under, or by applicable law with respect to, the Warrant Certificate held by such Holder.

9.2Rights of Action. All rights of action against the Company in respect of this Agreement, except rights of action vested in the Warrant Agent, are vested in the Holders of the Warrant Certificates, and any Holder of any Warrant Certificate, without the consent of the Warrant Agent or the Holder of any other Warrant Certificate, may, in such Holder’s own behalf and for such Holder’s own benefit, enforce and may institute and maintain any suit, action or proceeding against the Company suitable to enforce, or otherwise in respect of, such Holder’s right to exercise such Holder’s Warrants in the manner provided in this Agreement.

9.3Treatment of Holders of Warrant Certificates. Every Holder, by virtue of accepting a Warrant Certificate, consents and agrees with the Company, with the Warrant Agent and with every subsequent holder of such Warrant Certificate that, prior to due presentment of such Warrant Certificate for registration of transfer, the Company and the Warrant Agent may treat the Person in whose name the Warrant Certificate is registered as the owner thereof for all purposes and as the Person entitled to exercise the rights granted under the Warrants, and neither the Company, the Warrant Agent nor any agent thereof shall be affected by any notice to the contrary.

10.

(e) The Warrant Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorney or agents, and the Warrant Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorney or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct, absent gross negligence, willful misconduct, fraud or bad faith (each as determined by a final judgment of a court of competent jurisdiction) in the selection and continued employment thereof.

(f) The Warrant Agent may rely on and shall be held harmless and protected and shall incur no liability for or in respect of any action taken, suffered or omitted to be taken by it absent gross negligence, willful misconduct, fraud or bad faith (each as determined by a final judgment of a court of competent jurisdiction) in reliance upon any certificate, statement, instrument, opinion, notice, letter, facsimile transmission, telegram or other document, or any security delivered to it, and believed by it to be genuine and to have been made or signed by the proper party or parties, or upon any written or oral instructions or statements from the Company with respect to any matter relating to its acting as Warrant Agent hereunder.

(g) The Warrant Agent shall not be obligated to expend or risk its own funds or to take any action that it believes would expose or subject it to expense or liability or to a risk of incurring expense or liability, unless it has been furnished with assurances of repayment or indemnity satisfactory to it.

(j) The Warrant Agent shall act hereunder solely as agent for the Company, and its duties shall be determined solely by the express provisions hereof (and no duties or obligations shall be inferred or implied). The Warrant Agent shall not assume any obligations or relationship of agency or trust with any of the owners or holders of the Warrants.

(k) The Warrant Agent may rely on and be fully authorized and protected in acting or failing to act upon (a) any guaranty of signature by an “eligible guarantor institution” that is a member or participant in the Securities Transfer Agents Medallion Program or other comparable “signature guarantee program” or insurance program in addition to, or in substitution for, the foregoing; or (b) any law, act, regulation or any interpretation of the same even though such law, act, or regulation may thereafter have been altered, changed, amended or repealed.

(l) In the event the Warrant Agent believes any ambiguity or uncertainty exists hereunder or in any notice, instruction, direction, request or other communication, paper or document received by the Warrant Agent hereunder, the Warrant Agent, may, in its sole discretion, refrain from taking any action, and shall be fully protected and shall not be liable in any way to Company, the holder of any Warrant Certificate or any other person or entity for refraining from taking such action, unless the Warrant Agent receives written instructions signed by the Company which eliminates such ambiguity or uncertainty to the satisfaction of Warrant Agent.

(m) Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a statement signed by the Chairman of the Board, the Chief Executive Officer, the President, a Vice President, the Chief Financial Officer or the Secretary of the Company and delivered to the Warrant Agent.

Neither party to this Agreement shall be liable to the other party for any consequential, indirect, special or incidental damages under any provisions of this Agreement or for any consequential, indirect, punitive, special or incidental damages arising out of any act or failure to act hereunder even if that party has been advised of or has foreseen the possibility of such damages.

The Warrant Agent shall not be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant. The Warrant Agent shall not be responsible to make any adjustments required under the provisions ofSection 5 hereof or responsible for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Common Shares to be issued pursuant to this Agreement or any Warrant or as to whether any Common Shares shall, when issued, be valid and fully paid andnon-assessable.

10.3Indemnification.

(a) The Company covenants and agrees to indemnify and to hold the Warrant Agent harmless against any costs, expenses (including reasonable and documented fees of its legal counsel), losses or damages, which may be paid, incurred or suffered by or to which it may become subject, arising from or out of, directly or indirectly, any claims or liability resulting from its actions as Warrant Agent pursuant hereto; provided, that such covenant and agreement does not extend to, and the Warrant Agent shall not be indemnified with respect to, such costs, expenses, losses and damages incurred or suffered by the Warrant Agent as a result of, or arising out of, its gross negligence, bad faith, or willful misconduct (each as determined by a final decision of a court of competent jurisdiction).

(b)Instructions. From time to time, the Company may provide the Warrant Agent with instructions, by Company Order or otherwise, concerning the services performed by the Warrant Agent hereunder. In addition, at any time the Warrant Agent may apply to any officer of Company for instruction, and may consult with legal counsel for the Warrant Agent or the Company with respect to any matter arising in connection with the services to be performed by the Warrant Agent under this Warrant Agreement. Warrant Agent and its agents and subcontractors shall not be liable and shall be indemnified by Company for any action taken, suffered or omitted to be taken by Warrant Agent in reliance upon any Company instructions or upon the advice or opinion of such counsel. Warrant Agent shall not be held to have notice of any change of authority of any person, until receipt of written notice thereof from Company.

10.4Right to Consult Counsel.

Nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Company or for any other legal entity. 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.

10.7Resignation and Removal; Appointment of Successor.

(a) The Warrant Agent may resign its duties and be discharged from all further duties and liability hereunder (except liability arising prior to such resignation as a result of the Warrant Agent’s own gross negligence or willful misconduct each as determined in a finalnon-appealable decision of a court of competent jurisdiction) after giving 30 days’ prior written notice to the Company. In the event the transfer agency relationship in effect between the Company and the Warrant Agent terminates, the Warrant Agent will be deemed to have resigned automatically and be discharged from its duties under this Agreement as of the effective date of such termination. The Company may remove the Warrant Agent upon 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 withSection 11.1(b) to the Company of said notice of resignation. 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 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. The new Warrant Agent 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. The predecessor Warrant Agent shall not be required to make any additional expenditure (without assurance of reimbursement satisfactory to it) or assume any additional liability in connection with the foregoing. 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 thisSection 10.7(a), however, or any defect therein, shall not affect the legality or validity of the resignation of the Warrant Agent or the appointment of a new Warrant Agent as the case may be.

(b) Any Person into which the Warrant Agent or any new Warrant Agent may be merged, or any Person 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. Any such successor Warrant Agent shall promptly cause notice of its succession as Warrant Agent to be given in accordance withSection 11.1(b) to each Holder of a Warrant Certificate at such Holder’s last address as shown on the Warrant Register.

10.8Appointment 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 toSection 6, 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.

(b) Any Person 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 ofSection 10.8(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 withSection 11.1(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 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 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 thisSection 10.8 and the Warrant Agent shall be entitled to be reimbursed for such payments, subject to the provisions ofSection 10.5.

(e) Any Countersigning Agent shall have the same rights and immunities as those of the Warrant Agent set forthSection 10 and this Agreement.

(b) Where this Agreement provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, by trackable or first-class mail, to each Holder affected by such event, at the address of such Holder as it appears in the Warrant Register. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Agreement provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made by a method approved by the Warrant Agent as one which would be most reliable under the circumstances for successfully delivering the notice to the addressees shall constitute a sufficient notification for every purpose hereunder.

Where this Agreement provides for notice of any event to a Holder of a Global Warrant Certificate, such notice shall be sufficiently given if given to the Depositary (or its designee), pursuant to its Applicable Procedures, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice.

11.2Required Notices to Holders. In the event the Company shall:

(a) take any action that would result in an adjustment to the Exercise Price and/or the number of Common Shares issuable upon exercise of a Warrant pursuant toSection 5.1 or

(b) consummate any Transaction (each of (a) or (b), an “Action”);

then, in each such case, unless the Company has made a filing with the Commission, including pursuant to a Current Report on Form 8-K, which filing discloses such Action, the Company shall cause to be delivered to the Warrant Agent and shall give to each Holder of a Warrant Certificate, in accordance withSection 11.1(b) hereof, a written notice of such Action, including, in the case of an action pursuant toSection 11.2(a), the information required underSection 5.1(k)(ii). Such notice shall be given promptly after taking such Action.

If at any time the Company shall cancel any of the Actions for which notice has been given under thisSection 11.2 prior to the consummation thereof, the Company shall give each Holder prompt notice of such cancellation in accordance withSection 11.1(b), unless the Company has made a filing with the Commission, including pursuant to a current report on Form 8-K, which filing discloses the cancellation of such Actions.

If at any time the Board of Directors of the Company shall determine (I) the fair market value of anynon-cash property distributed on the Common Shares pursuant toSection 5.1(d), (II) the value of anynon-cash consideration payable in a tender or exchange offer pursuant toSection 5.1(e), (III) the Current Market Price pursuant to clause (ii) of the definition thereof or (IV) the value of a unit of Reference Property pursuant toSection 5.1(h)(i)(A), the Company shall provide written notice of such determination to each Holder of a Warrant Certificate promptly after making such determination.

In addition, in the event the Company enters into any definitive agreement with respect to any Transaction, unless the Company has made a filing with the Commission, including pursuant to a Current Report on Form 8-K, which filing discloses such agreement, the Company shall cause to be delivered to the Warrant Agent and shall give to each Holder of a Warrant Certificate, in accordance withSection 11.1(b), a notice of the entering into such definitive agreement.

12.

Inspection.

The Warrant Agent shall cause a copy of this Agreement to be available for inspection by any Holder of any Warrant Certificate during the Warrant Agent’s normal business hours at the office of the Warrant Agent designated for such purpose. The Warrant Agent may require any such Holder to submit its Warrant Certificate for inspection by the Warrant Agent.

13.

Amendments.

(a) This Agreement may be amended by the Company and the Warrant Agent with the consent of the Required Warrant Holders.

(b) Notwithstanding the foregoing, the Company and the Warrant Agent may, without the consent or concurrence of the Holders of the Warrant Certificates, by supplemental agreement or otherwise, amend this Agreement for the purpose of making any changes or corrections in this Agreement that (i) are required to cure any ambiguity or to correct or supplement any defective or inconsistent provision or clerical omission or mistake or manifest error herein contained or (ii) add to the covenants and agreements of the Company in this Agreement further covenants and agreements of the Company thereafter to be observed, or surrender any rights or powers reserved to or conferred upon the Company in this Agreement;provided,however, that in either case such amendment shall not adversely affect the rights or interests of the Holders of the Warrant Certificates hereunder in any material respect.

(c) Notwithstanding anything to the contrary herein, the consent of each Holder of any Warrant Certificate evidencing any Warrants affected thereby shall be required for any supplement or amendment to this Agreement or the Warrants, or any waiver thereof, that would: (i) increase the Exercise Price or decrease the number of Common Shares receivable upon exercise of Warrants, in each case other than as provided inSection 5.1; (ii) change the Expiration Date to an earlier date; (iii) modify the provisions contained inSection 5.1 in a manner adverse to the Holders of Warrant Certificates generally with respect to their Warrants; (iv) modify the provisions of thisSection 13; (v) modify the provisions ofSection 3.2(b); or (vi) make any change that adversely affects the exercise rights of the Warrants.

(d) The Warrant Agent shall join with the Company in the execution and delivery of any such amendment unless such amendment affects the Warrant Agent’s own rights, duties or immunities hereunder (as determined by the Warrant Agent), in which case the Warrant Agent may, but shall not be required to, join in such execution and delivery;provided,that, as a condition precedent to the Warrant Agent’s execution of any amendment to this Agreement, the Company shall deliver to the Warrant Agent a certificate from an Appropriate Officer that states that the proposed amendment is in compliance with the terms of thisSection 13. No supplement or amendment to this Agreement shall be effective unless duly executed by the Warrant Agent. Upon execution and delivery of any amendment pursuant to thisSection 13, such amendment shall be considered a part of this Agreement for all purposes and every Holder of a Warrant Certificate theretofore or thereafter countersigned and delivered hereunder shall be bound thereby.

(e) Promptly after the execution by the Company and the Warrant Agent of any such amendment, unless the Company has made a filing with the Commission, including pursuant to a current report on Form 8-K, which filing discloses such adjustment, the Company shall give notice to the Holders of Warrant Certificates, setting forth in general terms the substance of such amendment, in accordance with the provisions ofSection 11.1(b). Any failure of the Company to mail such notice or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment.

14.

Waivers.

The Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Required Warrant Holders, as required pursuant toSection 13, subject toSection 13(c).

The Warrants evidenced hereby are one of a duly authorized issue of Warrants of the Company designated as its Warrants to Purchase Common Shares (“Warrants”), limited in aggregate number to 10,919,499 issued under and in accordance with the Warrant Agreement, dated as of December 21, 2018 (the “Warrant Agreement”), between the Company, Computershare Inc., a Delaware corporation (“Computershare”), and its wholly-owned subsidiary Computershare Trust Company, N.A., a federally chartered trust company (collectively, the “Warrant Agent”, which term includes any successor thereto permitted under the Warrant Agreement), to which the Warrant Agreement and all amendments thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Warrant Agent, the Holders of Warrant Certificates and the owners of the Warrants evidenced thereby and of the terms upon which the Warrant Certificates are, and are to be, countersigned and delivered. A copy of the Warrant Agreement shall be available at all reasonable times at the office of the Warrant Agent for inspection by the Holder hereof.

The Warrant Agreement provides that, in addition to certain adjustments to the number of Common Shares into which a Warrant is exercisable and the Exercise Price required to be made in certain circumstances, in the case of any Transaction (other than a Cash Transaction) the Company shall cause the other Person involved in such Transaction to execute and deliver to the Warrant Agent a written instrument providing that (i) the Warrants evidenced hereby, if then outstanding, will be exercisable thereafter, during the period the Warrants evidenced hereby shall be exercisable as specified herein, only into the Reference Property that would have been receivable upon such Transaction by a holder of the number of Common Shares that would have been issued upon exercise of such Warrant if such Warrant had been exercised in full immediately prior to such Transaction (upon certain assumptions specified in the Warrant Agreement); and (ii) the rights and obligations of the other Person involved in such Transaction and the holders in respect of Reference Property shall be substantially unchanged to be as nearly equivalent as may be practicable to the rights and obligations of the Company and Holders in respect of Common Shares.

Except as provided in the Warrant Agreement, all outstanding Warrants shall expire and all rights of the Holders of Warrant Certificates evidencing such Warrants shall automatically terminate and cease to exist, as of 5:00 p.m., New York time, on the Expiration Date. The “Expiration Date” shall mean the earliest to occur of (x) July 14, 2025; (y) the date of consummation of a Cash Transaction to which clause (iii) ofSection 5.1(h) of the Warrant Agreement applies; and (z) a Winding Up.

In the event of the exercise of less than all of the Warrants evidenced hereby, a new Warrant Certificate of the same tenor and for the number of Warrants which are not exercised shall be issued by the Company in the name or upon the written order of the Holder of this Warrant Certificate upon the cancellation hereof.

The Warrant Certificates are issuable only in registered form in denominations of whole numbers of Warrants. Upon surrender at the office of the Warrant Agent and payment of the charges specified herein and in the Warrant Agreement, this Warrant Certificate may be exchanged for Warrant Certificates in other authorized denominations or the transfer hereof may be registered in whole or in part in authorized denominations to one or more designated transferees;provided,however, that such other Warrant Certificates issued upon exchange or registration of transfer shall evidence the same aggregate number of Warrants as this Warrant Certificate. The Company shall cause to be kept at the office or offices of the Warrant Agent 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. No service charge shall be made for any registration of transfer or exchange of Warrant Certificates;provided,however, the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Warrant Certificates.

Prior to due presentment of this Warrant Certificate for registration of transfer, the Company, the Warrant Agent and any agent of the Company or the Warrant Agent may treat the Person in whose name this Warrant Certificate is registered as the owner hereof for all purposes, and neither the Company, the Warrant Agent nor any such agent shall be affected by notice to the contrary.

The Warrant Agreement permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of Warrant Certificates under the Warrant Agreement at any time by the Company and the Warrant Agent with the consent of the Required Warrant Holders.

Until the exercise of any Warrant, subject to the provisions of the Warrant Agreement and except as may be specifically provided for in the Warrant Agreement, (i) no Holder of a Warrant Certificate evidencing any Warrant shall have or exercise any rights by virtue hereof as a holder of Common Shares of the Company, including, without limitation, the right to vote, to receive dividends and other distributions or to receive notice of, or attend meetings of, stockholders or any other proceedings of the Company; (ii) the consent of any such Holder shall not be required with

respect to any action or proceeding of the Company; (iii) except as provided with respect to a Winding Up of the Company, no such Holder, by reason of the ownership or possession of a Warrant or the Warrant Certificate representing the same, shall have any right to receive any cash dividends, stock dividends, allotments or rights or other distributions (except as specifically provided in the Warrant Agreement), paid, allotted or distributed or distributable to the stockholders of the Company prior to or for which the relevant record date preceded the date of the exercise of such Warrant; and (iv) no such Holder shall have any right not expressly conferred by the Warrant or Warrant Certificate held by such Holder.

This Warrant Certificate, each Warrant evidenced thereby and the Warrant Agreement shall be governed by and construed in accordance with the laws of the State of New York.
