Any such Definitive Warrants shall bear such restrictive legends as the Company may instruct.

(c) Subject to the provisions of Section 2.05(b), the registered Holder of a Global Warrant may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Agreement or the Warrants.

Such Holder shall furnish an open penalty surety bond sufficient in the judgment of the Company and the Warrant Agent to protect the Company and the Warrant Agent from any loss that either of them may suffer if a Warrant Certificate is replaced. The Warrant Agent may, at its option, issue replacement Warrants for mutilated certificates upon presentation thereof without such indemnity. The Company and the Warrant Agent may charge the Holder for their expenses in replacing a Warrant Certificate. Every replacement Warrant Certificate evidences an additional obligation of the Company.

Warrants outstanding at any time are all Warrants evidenced as outstanding in the Warrant Register (which, in the case of Warrants represented by Warrant Certificates, shall include all Warrant Certificates authenticated by the Warrant Agent excluding those canceled by it and those delivered to it for cancellation).

(iii) either to the extent the Company determines to settle such exercise through Full Settlement, (A) payment in United States dollars by certified or official bank check payable to the order of the Company or by wire transfer of immediately available funds to an account of the Company (as designated by the Company by notice in writing to the Holders pursuant to Section 8.04) or (B) no earlier than the Business Day following the Exercise Date, surrendering notes of an applicable series of Designated Notes (with a principal amount of $1,000 or any whole multiple thereof) with a stated aggregate principal amount (regardless of the then current market value of such Designated Notes), excluding any accrued and unpaid interest, if any, as of the applicable date of surrender, in each case equal (or, in the case of surrender pursuant to clause (iii)(B) in an amount at least equal) to the Exercise Price multiplied by the number of Common Shares. (excluding the Incentive Share Fraction, if any) hereby purchased, subject, in the case of Designated Notes held through the Depositary, to the Depositary’s applicable procedures and the relevant Holder effecting, or arranging for, the transfer of such Designated Notes through the Depositary’s deposit and withdrawal at custodian (DWAC) system. For the avoidance of doubt, to the extent the Company determines to settle such exercise through Net Share Settlement, no payment of cash or Designated Notes will be required to be made by the Holders and the Exercise Price will be deemed to be paid by issuance of the aggregate Per Share Net Share Settlement Amount.

(b)  In the case of a Global Warrant, any Person with a beneficial interest in such Global Warrant shall effect compliance with the requirements in Section 3.04(a)(i), (ii) and (iii) above through the relevant Agent Member in accordance with the procedures of the Depositaryprotocols set forth on Exhibit C of the Warrant Certificate, except in the case of transactions described in clause (iii)(B), in which case such requirements shall be satisfied in accordance with the protocol set forth on Exhibit B of the Warrant Certificate, or in accordance with such other procedures as shall be agreed by the Company and the Warrant Agent. All principal of the applicable series of Designated Notes surrendered pursuant to Section 3.04(a)(iii)(B) in excess of the Exercise Price multiplied by the number of Common Shares (excluding the Incentive Share Fraction, if any) thereby purchased shall be forfeited to the Company by the Holder surrendering such Designated Notes and shall not be refunded to such Holder.

(c) All unpaid interest that has accrued up to, but excluding, the date that any notes of an applicable series of Designated Notes are duly surrendered pursuant to Section 3.04(a)(iii)(B) (including interest on the amount deemed forfeited pursuant to Section 3.04(b), if any) shall be forfeited to the Company by the Holder surrendering such Designated Notes and shall not be refunded to such Holder; provided if such Designated Note is surrendered between a record date and interest payment date, interest will be paid on the interest payment date with respect to the principal balance of the Designated Note as of the record date.

(d) If any of (w) the Warrant Certificate or (x) the election to purchase Warrant Shares, is received by the Warrant Agent after 5:00 P.M., New York time, on the date specified in Section 3.04(a), the Warrants

will be deemed to be received and exercised on the next succeeding Business Day, which shall be the Exercise Date thereof. If the date specified as the Exercise Date is not a Business Day, the Warrants will be deemed to be received and exercised on the next succeeding day which is a Business Day. If the Warrants are received or deemed to be received after the Expiration Date, the exercise thereof will be null and void and any funds delivered to the Warrant Agent will be returned to the Holder as soon as practicable. In no event will interest accrue on funds deposited with the Warrant Agent in respect of an exercise or attempted exercise of Warrants.

(e) In the case of a Global Warrant, whenever some but not all of the Warrants represented by such Global Warrant are exercised in accordance with the terms thereof and of this Agreement, such Global Warrant shall be surrendered by the Holder to the Warrant Agent, which shall cause an adjustment to be made to such Global Warrant so that the number of Warrants represented thereby will be equal to the number of Warrants theretofore represented by such Global Warrant less the number of Warrants then exercised. The Warrant Agent shall thereafter promptly return such Global Warrant to the Holder or its nominee or custodian.

(f) In the case of a Definitive Warrant, whenever some but not all of the Warrants represented by such Definitive Warrant are exercised in accordance with the terms thereof and of this Agreement, the Holder shall be entitled, at the request of the Holder, to receive from the Company within a reasonable time, and in any event not exceeding ten (10) Business Days, a new Definitive Warrant in substantially identical form for the number of Warrants equal to the number of Warrants theretofore represented by such Definitive Warrant less the number of Warrants then exercised.

(g) If a Warrant Certificate shall have been exercised in full, the Warrant Agent shall promptly cancel such certificate following its receipt from the Holder or the Depositary, as applicable.

(h) Notwithstanding the foregoing, or anything in Section 8.03 to the contrary, the Company shall have the right, in its sole discretion, to (i) alter, waive, revise, adjust, change or modify the requirements, time periods or other mechanics of the process of exercising the Warrants. (provided that any such modified mechanics of exercise shall be consistent with the customary procedures of the Warrant Agent), (ii) to change the Default Settlement Mechanic and (iii) to choose a Settlement Mechanic (including choosing different Settlement Mechanics for Warrants exercised on the same Exercise Date) in connection with any particular exercise of a Warrant.

(i) If a Common Share Shelf Registration Statement is not effective at the Exercise Date or a prospectus relating to the issuance of Warrant Shares is not current, the Holders will be able to exercise their Warrants only on a net share settled basisthrough Net Share Settlement pursuant to the exemption from the registration requirements of the Securities Act under Section 3(a)(9) and as described in Section 3.05(b).

SECTION 3.05. Issuance of Warrant SharesSettlement.

(c) The Company shall provide the cost basis information to the Warrant Agent, as applicable:

(i) In the event of an exercise with cash or with Designated Notespursuant to which the Company determines Full Settlement shall apply, the Company hereby instructs the Warrant Agent to record cost basis for newly issued shares as follows:

(1) in the event of an exercise with cash, the Warrant Agent shall record cost basis for newly issued shares as the sum of (x) the Exercise Price plus (y) the Holder’s cost basis in the exercised Warrant, if any, which the Warrant Agent shall request of the Holder, if necessary (unless the Company has provided reasonable written notice to the Warrant Agent to use a different method of calculating cost basis, as reasonably determined by the Company, at the time of or prior to such exercise), and

(2) in the event of an exercise with Designated Notes, the Warrant Agent shall record cost basis of newly issued shares as the sum of (x) the fair market value of the Designated Notes tendered in exercise as of the date of exercise (as reasonably determined by the Company) plus (y) the Holder’s cost basis in the exercised Warrant, if any, which the Warrant Agent shall request of the Holder, if necessary (unless the Company has provided reasonable written notice to the Warrant Agent to use a different method of calculating cost basis, as reasonably determined by the Company, at the time of or prior to such exercise).

(ii) In the event of an exercise of a Warrant on a net share settled basispursuant to which the Company determines Net Share Settlement shall apply, the Company shall provide instructions for computing cost basis for shares issued pursuant to such exercise at the time the Company confirms the number of CommonWarrant Shares issuable in connection with such exercise.

(d) the Warrant Agent shall have no duty or obligation to investigate or confirm whether the Company’s determination of the number of CommonWarrant Shares to be issued on such exercise, pursuant to this Agreement, is accurate or correct.

SECTION 3.06. Fractional Warrant Shares. The Company shall not be required to issue fractional Common Shares on the exercise of Warrants or pay cash in lieu thereof. The number of full Common Shares that shall be issuable upon an exercise of Warrants by a Holder at any time shall be computed on the basis of the aggregate number of Common Shares which may be purchased pursuant to the Warrants being exercised by that Holder at that time. If any fraction of a Common Share would be issuable upon the exercise of Warrants, the Company shall round down the total number of Common Shares to be issued to the relevant Holder to the nearest whole number.

SECTION 3.07. Reservation of Warrant Shares.

(a) The Company shall at all times keep reserved out of its authorized Common Shares a number of Common Shares sufficient to provide for the exercise of all outstanding Warrants, including the maximum number of the Incentive Share Fraction. The Company will keep a copy of this Agreement on file with the Stock Transfer Agent and will furnish to such Stock Transfer Agent a copy of all notices of adjustments (and certificates related thereto) transmitted to each Holder.

(b) The Company covenants that all Warrant Shares that may be issued upon proper exercise of Warrants (including payment of the Exercise Price, if applicable) shall, upon issue, be fully paid, nonassessable, free of preemptive rights.

(c) The Company shall provide an opinion of counsel which shall state that all Warrants or Warrant Shares, as applicable, are or will be, upon issuance, registered under the Securities Act, as amended, or are exempt from such registration, and validly issued, fully paid and nonassessable.

SECTION 3.08. Ownership Limitation.

(a) Notwithstanding any other provision in this Agreement, a Holder of a Warrant shall not be permitted to exercise Warrants for any Common Shares if, following such exercise, the Holder will have Beneficial Ownership of Common Shares in excess of 4.9% of the then issued and outstanding (excluding Common Shares held by subsidiaries of the Company) Common Shares (the “Ownership Limitation”); provided that if any Holder Beneficially Owns Common Shares in excess of the Ownership Limitation at 5:00 pm on May 27, 2021, such Holder shall have the right to exercise any Warrants (and receive the related Common Shares) received by such Holder in connection with the Warrant Distribution.

(b) Any exercise of Warrants contrary to the Section 3.08(a) shall be void ab initio to the extent of such violation.

(c) The Company will publish the total number of issued and outstanding Common Shares (less shares held by subsidiaries of the Company) on its website and with the Warrant Agent weekly while Warrants remain outstanding.

SECTION 4.01. Adjustments. Subject to the provisions of this Article IV, the Exercise Price and the number of Warrants Shares shall be subject to adjustment, without duplication, as follows, except that the Company shall not make any such adjustments if each Holder participates, at the same time and upon the same terms as holders of the Common Shares and solely as a result of holding the Warrants in any of the transactions described in this Section 4.01, without having to exercise such Holder’s Warrants, as if such Holder held a number of Common Shares equal to the number of Warrant Shares:

(a) Stock Dividends, Splits, Subdivisions, Reclassifications, Combinations and similar transactions. If the Company shall (i) issue Common Shares as a dividend or make a distribution of its Common Shares, (ii) subdivide or reclassify the issued and outstanding Common Shares into a greater number of shares, or (iii) combine, consolidate or reclassify the issued and outstanding Common Shares into a smaller number of shares then, in such event:

(i) the number of Warrant Shares immediately prior to the open of business on the Ex-Date for such dividend or distribution or the effective date of such subdivision, combination, consolidation or reclassification shall be proportionately adjusted so that the Holder after such date shall be entitled to purchase the number of Common Shares that such Holder would have owned or been entitled to receive in respect of the Warrant Shares after such date had such Warrant been exercised immediately prior to such date; and

(ii) the Exercise Price in effect immediately prior to the open of business on the Ex-Date for such dividend or distribution or the effective date of such subdivision, consolidation, combination or reclassification shall be adjusted based on the following formula:

Any adjustment made under this clause (a) shall become effective immediately after the open of business on such Ex-Date for such dividend or distribution, or immediately after the open of business on the effective date for such share split, share combination, reclassification, combination or similar transaction as applicable. If any dividend or distribution of the type described in this clause (a) is declared but not so paid or made, the Exercise Price and number of Warrant Shares shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Exercise Price and number of Warrant Shares that would then be in effect if such dividend or distribution had not been declared.

(b) Certain Issuances of Common Shares or Convertible Securities. If the Company shall issue Common Shares (or rights or warrants or other securities exercisable or convertible into or exchangeable (collectively, a “conversion”) for Common Shares (collectively, “convertible securities”)) (other than in Permitted Transactions (as defined below) or a transaction to which Section 4.01(a), 4.01(c) or 4.01(f) is applicable) without consideration or at a consideration per share in the case of Common Shares (or, in the case of convertible securities, having a conversion price per share) that is less than 95% of the Market Price on the last Trading Day preceding the date on which the relevant sales price, conversion price or exercise price is established then, in such event:

(i) the number of Warrant Shares immediately prior to the open of business on the date on which the sales price, conversion price or exercise price is established (the “Ex-Date”) shall be adjusted based on the following formula:

(ii) the Exercise Price payable upon exercise of a Warrant shall be adjusted by the following formula:

Any adjustment made under this clause (b) shall be made successively whenever any such convertible securities are distributed and shall become effective immediately after the open of business on the Ex-Date for such distribution. To the extent that Common Shares are not delivered after the expiration of such convertible securities, the Exercise Price and number of Warrant Shares shall be adjusted to the Exercise Price and number of Warrant Shares that would then be in effect had the adjustment with respect to the distribution of such convertible securities been made on the basis of delivery of only the number of Common Shares actually delivered. If such convertible securities are not so distributed, the Exercise Price and number of Warrant Shares shall be decreased to the Exercise Price and number of Warrant Shares that would then be in effect if such Ex-Date for such distribution had not occurred.

For purposes of the foregoing, the aggregate consideration receivable by the Company in connection with the issuance of such Common Shares or convertible securities shall be deemed to be equal to the sum of the net offering price (after deduction of any related expenses payable to third parties) of all such securities plus the minimum aggregate amount, if any, payable upon exercise or conversion of any such convertible securities into Common Shares; and “Permitted Transactions” shall include issuances (1) as consideration for or to fund the acquisition by the Company of businesses and/or assets, (2) in connection with employee benefit plans and compensation related arrangements of the Company approved by the Board of Directors, (3) in connection with a broadly marketed offering and sale of Common Shares or convertible securities for cash and (4) upon exercise of convertible securities issued and outstanding on the date hereof or in accordance with the terms (whether mandatory or optional) of any security, instrument or agreement outstanding or in effect on the date hereof. Any adjustment made pursuant to this Section 4.01(b) shall become effective immediately upon the date of such issuance.

(c) Other Distributions and Spin-Offs.

(i) Distributions Other than Spin-Offs. If the Company makes a distribution to all holders of its Common Shares, of its Capital Stock, evidences of indebtedness, assets or property of the Company, cash, rights or warrants, excluding:

(1) dividends or distributions described in clause (a) or (b) above;

(2) dividends or distributions paid exclusively in cash described in clause (d) below;

(3) any dividends or distributions in connection with a business combination, reclassification, change, consolidation, merger, conveyance, transfer, sale, lease or other disposition resulting in the change in the securities or property receivable upon the exercise of a warrant as described in Section 4.03;

(4) rights issued pursuant to a shareholders’ rights plan adopted by the Company as described in clause (f); and

(5) Spin-Offs described below in Section 4.01(c)(ii);

then the Exercise Price shall be decreased based on the following formula:

(ii) Spin-Offs. With respect to an adjustment pursuant to this clause (c) where there has been a payment of a dividend or other distribution on the Common Shares in shares of Capital Stock of any class or series, or similar equity interests, of or relating to a Subsidiary or other business unit of the Company that will be, upon distribution, listed or quoted on a U.S. national or regional securities exchange (a “Spin-Off”), the Warrant Shares shall be adjusted based on the following formula:

the Exercise Price in effect immediately prior to the open of business for the Ex-Date for the Spin-Off shall be adjusted based on the following formula:

Any adjustment to the Exercise Price and number of Warrant Shares under the preceding paragraph of this clause (c) shall be made immediately after the close of business on the last day of the Valuation Period, but shall be given effect as of the open of business on the Ex-Date for the Spin-Off. If any distribution of the type described in this Section 4.01(c) is declared but not so made, the Exercise Price and number of Warrant Shares shall be immediately readjusted, effective as of the date the Board of Directors determines not to make such distribution, to the Exercise Price and number of Warrant Shares that would then be in effect if such distribution had not been declared.

(d) Cash Dividends or Distributions. If any cash dividend or distribution is made to all or substantially all holders of Common Shares, other than a regular quarterly cash dividend that does not exceed the Dividend Threshold per Common Share then:

(i) the number of Warrant Shares shall be adjusted based on the following formula:

(ii) the Exercise Price payable upon exercise of the Warrants shall be adjusted based on the following formula:

Any increase made under this clause (d) shall become effective immediately after the open of business on the Ex-Date for such dividend or distribution. If such dividend or distribution is not so paid, the Exercise Price and number of Warrant Shares shall be adjusted, effective as of the date the Board of Directors, or a committee thereof, determines not to make or pay such dividend or distribution, to be the Exercise Price and number of Warrant Shares that would then be in effect if such dividend or distribution had not been declared.

(e) Certain Repurchases of Common Shares. In case the Company effects a Pro Rata Repurchase of Common Shares at a price per Common Share above reported Market Price, then:

(i) the Exercise Price shall be adjusted based on the following formula:

(ii) the number of Warrant Shares shall be adjusted based on the following formula:

Any adjustment to the Exercise Price and number of Warrant Shares under this clause (e) shall occur at the close of business on the tenth Trading Day immediately following, and including, the Trading Day next succeeding the Effective Date. If such repurchase is not so effected, the Exercise Price and number of Warrant Shares shall be readjusted to be the Exercise Price and number of Warrant Shares that would then be in effect if such Pro Rata Repurchase had not been declared.

(f) Certain Rights or Warrants; Shareholder Rights Plan. (i) In case the Company shall distribute or shall be deemed to have distributed, or shall fix a record date for the making of a distribution, to all holders of its Common Shares of rights or warrants pursuant to a shareholder rights plan commonly known as a “poison pill” (a “Rights Plan”), which rights or warrants are not exercisable until the occurrence of a specified event or events (a “Trigger Event”), in each such case, upon the occurrence of the earliest such Trigger Event, the Exercise Price in effect prior to such Trigger Event shall be adjusted immediately after such Trigger Event based on the following formula:

such adjustment shall be made successively whenever any Trigger Event occurs under any Rights Plan and, with respect to any Rights Plan with respect to which an adjustment has been made, a corresponding adjustment shall be made successively whenever any subsequent adjustment to the applicable rights or warrants is made pursuant to the terms of such Rights Plan to the extent such adjustment has not been made pursuant to the other terms of the Warrants. In such event, the number of Warrant Shares shall be adjusted based on the following formula:

(i) In the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event with respect thereto described in clause (i) of this Section 4.01(f):

(1) upon the redemption or repurchase by the Company of any such rights or warrants without exercise by the holders thereof, (x) in the event that a Trigger Event shall have occurred and an adjustment to the Exercise Price and number of shares issuable upon exercise of a Warrant shall have been made pursuant to clause (i) of this Section 4.01(f), the Exercise Price and number of Warrant Shares shall be readjusted as if such rights or warrants had not been distributed, and (y) whether or not a Trigger Event shall have occurred, the Exercise Price and the number of Warrant Shares shall be adjusted or readjusted, as applicable, pursuant to the terms of Section 4.01(c) upon such redemption or repurchase as though it were a cash distribution (but not an Ordinary Cash Dividend) equal to the per share redemption or repurchase consideration received by holders of Common Shares with respect to such rights or warrants (assuming such holder had retained such rights or warrants) made to all holders of Common Shares as of the date of such redemption or repurchase, it being understood that if a readjustment has occurred pursuant to clause (x) above, the readjustment described in this clause (y) shall occur immediately following such readjustment made pursuant to clause (x); and

(2) in the event that a Trigger Event shall have occurred and an adjustment to the Exercise Price and number of Warrant Shares shall have been made pursuant to clause (i) of this Section 4.01(f), in the case all such rights or warrants shall have expired or been terminated without exercise by any holders thereof, the Exercise Price and the number of Warrant Shares shall be readjusted as if such rights and warrants had not been distributed.

(ii) If the Company has a Rights Plan in effect with respect to its Common Shares, upon exercise of a Warrant, notwithstanding anything to the contrary in such Rights Plan, including any rights agreement or documents or instruments entered into as part of such Rights Plan, the Holder shall be entitled to receive, in addition to the Warrant Shares, a corresponding number of rights under such Rights Plan, unless (A) a Trigger Event occurs prior to such exercise, in which case the adjustments (if any are required) to the Exercise Price and the number of Warrant Shares with respect thereto shall be made in accordance with clause (i) of this Section 4.01(f), or (B) the Holder has provided written notice to the Company that it has elected not to receive such rights.

(iii) Any adjustment to the Exercise Price and the number of Warrant Shares pursuant to this Section 4.01(f) shall be made subject in all respects to the other provisions of this Section 4.01 (but without duplication); provided that Section 4.01(c) shall not apply, and shall be superseded by this Section 4.01(f), with respect to rights or warrants distributed (or deemed distributed) by the Company pursuant to a Rights Plan, except as expressly provided in clause (ii) of this Section 4.01(f).

(g) Other Adjustments. In addition, the Company may, but shall not be required to, make such decreases in the Exercise Price, in addition to those required by this Section 4.01, as the Board of Directors considers to be advisable for any reason, including, without limitation, in order to avoid or diminish any income tax to any holders of Common Shares or to any Holders of Warrants resulting from any dividend or distribution of shares or from any event treated as such for income tax purposes or for any other reason.

SECTION 4.02. Calculation of Adjustments; Timing of Issuance of Additional Warrant Shares Upon Certain Adjustments; Adjustment Rules.

(a) All calculations under Section 4.01 shall be made to the nearest one-tenth (1/10th) of a cent or to the nearest one-hundredth (1/100th) of a share, as the case may be. Any provision of Section 4.01 to the contrary notwithstanding, no adjustment in the Exercise Price or the number of Warrant Shares shall be made if the amount of such adjustment would be less than $0.01 or one-tenth (1/10th) of a Common Share, but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent adjustment that, together with such amount and any other amount or amounts so carried forward, shall aggregate $0.01 or 1/10th of a Common Share, or more.

(b) In any case in which the provisions of Section 4.01 shall require that an adjustment shall become effective immediately after an Ex-Date for an event, the Company may defer until the occurrence of such event issuing to the Holder of a Warrant exercised after such record date and before the occurrence of such

event the additional Warrant Shares issuable upon such exercise by reason of the adjustment required by such event over and above the Warrant Shares issuable upon such exercise before giving effect to such adjustment; provided, however, that the Company upon request shall deliver to such Holder a due bill or other appropriate instrument evidencing such Holder’s right to receive such additional shares upon the occurrence of the event requiring such adjustment.

(c) Any adjustments pursuant to Section 4.01 shall be made successively whenever an event referred to therein shall occur. If an adjustment in Exercise Price made under Section 4.01 would reduce the Exercise Price to an amount below the par value of the Common Shares, then such adjustment in the Exercise Price shall reduce the Exercise Price to the par value of the Common Shares.

SECTION 4.03. Business Combinations and Reorganizations. In case of any Business Combination or reclassification of Common Shares (other than a reclassification of Common Shares referred to in Section 4.01), the Holder’s right to receive Warrant Shares upon exercise of a Warrant shall be converted into the right to exercise a Warrant to acquire the number of shares or other securities or property (including cash) that the Warrant Shares (at the time of such Business Combination or reclassification) immediately prior to such Business Combination or reclassification would have been entitled to receive upon consummation of such Business Combination or reclassification (the amount of such shares, other securities or property in respect of a Common Share being herein referred to as a “Unit of Reference Property”); and in any such case, if necessary, the provisions set forth herein with respect to the rights and interests thereafter of the Holder shall be appropriately adjusted so as to be applicable, as nearly as may reasonably be achievable, to the Holder’s right to exercise such Warrant in exchange for a Unit of Reference Property pursuant to this paragraph. If the Business Combination 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 shareholder election), then the composition of the Unit of Reference Property into which the Warrants will be exercisable shall be deemed to be the weighted average of the types and amounts of consideration actually received by the holders of Common Shares.

SECTION 4.04. Notice of Adjustments. Whenever any adjustment is made pursuant to this Article IV, the Company shall cause notice of such adjustment to be delivered to the Warrant Agent promptly following the effective date of such adjustment, such notice to include in reasonable detail (i) the reason for the adjustment, (ii) the computation of any adjustments, and (iii) the new or amended exercise terms, including, as applicable, the Exercise Price, the number of shares or the Units of Reference Property purchasable upon exercise of each Warrant after giving effect to such adjustment. The calculations, adjustments and determinations included in the Company’s notice shall, absent manifest error, be final and binding on the Company, the Warrant Agent and the Holders. The Warrant Agent shall be entitled to rely on such notice and any adjustment therein contained and the Warrant Agent shall not be deemed to have knowledge of any such adjustment unless and until it shall have received such notice. The Warrant Agent shall have no obligation under any section of this Agreement to determine whether an adjustment is required or to calculate any of the adjustments set forth herein. The Warrant Agent shall within fifteen (15) days after receipt of such notice from the Company (which notice must specifically direct the Warrant Agent to perform the mailing) cause a similar notice to be delivered to each Holder.

SECTION 4.05. Adjustment to Warrant Certificate. The form of Warrant Certificate need not be changed because of any adjustment made pursuant to this Article IV, and Warrant Certificates issued after such adjustment may state the same Exercise Price and the same number of Warrant Shares as are stated in any Warrant Certificates issued prior to such adjustment. The Company, however, may at any time in its sole discretion make any change in the form of Warrant Certificate that it may deem appropriate to give effect to such adjustments and that does not affect the substance of the Warrant Certificate, and any Warrant Certificate thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant Certificate or otherwise, may be in the form as so changed. For the avoidance of doubt, no change to the Warrant Certificate or this Agreement as a result of an adjustment pursuant to this Article IV shall require the consent of the Holders of the Warrants or the Warrant Agent.

SECTION 5.01. Effectiveness of Registration Statement. The Company shall use commercially reasonable efforts to cause a shelf registration statement (including, at the Company’s election, an existing registration statement), filed pursuant to Rule 415 (or any successor provision) of the Securities Act, covering the issuance of

Warrant Shares to the Holders upon exercise of the Warrants by the Holders thereof (the “Common Share Shelf Registration Statement”) to (i) become effective as promptly as reasonably practicable after the date of this Agreement and (ii) remain effective until the earlier of (x) such time as all Warrants have been exercised and (y) the Expiration Date. The Company shall promptly inform the Warrant Agent of any change in the status of the effectiveness or availability of the Common Share Shelf Registration Statement. For the avoidance of doubt, no Warrants shall be exercisable at any time until a Common Share Shelf Registration Statement becomes effective. Notwithstanding the foregoing, if a Common Share Shelf Registration Statement covering the issuance of the Warrant Shares at the time of exercise of any Warrants is not effective or a prospectus relating thereto is not current, the Holders will be able to exercise their Warrants only on a net share settled basisthrough Net Share Settlement by surrendering their Warrants in exchange for Common Sharesthe Settlement Amount as described in Section 3.05(b) and, if applicable, pursuant to the exemption from the registration requirements of the Securities Act under Section 3(a)(9).

SECTION 5.02. Suspension. The Company shall be entitled to suspend the availability of the Common Share Shelf Registration Statement from time to time during any consecutive 365-day period for a total not to exceed 90 days during such consecutive 365-day period if the Board of Directors determines in the exercise of its reasonable judgment that such suspension is necessary in order to comply with applicable laws and provides notice that such determination was made to the Holders of the Warrants; provided, however, that (i) if the Company exercises such right in the 90 consecutive-day period immediately prior to the Expiration Date, the Expiration Date shall be delayed by the number of days during such 90-day period for which the availability of the Common Share Shelf Registration Statement was suspended and (ii) in no event shall the Company be required to disclose the business purpose for such suspension if the Company determines in good faith that such business purpose must remain confidential.

SECTION 5.03. Blue Sky. The Company shall use commercially reasonable efforts to register or qualify the Warrant Shares under all applicable securities laws, blue sky laws or similar laws of all jurisdictions in the United States in which any Holder may or may be deemed to purchase Warrant Shares upon the exercise of Warrants and shall use commercially reasonable efforts to maintain such registration or qualification for so long as it is required to cause the Common Share Shelf Registration Statement to remain effective under the Securities Act pursuant to Section 5.01; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction in which it would not otherwise be required to qualify but for this Section 5.03 or to take any action that would subject it to general service of process or to taxation in any such jurisdiction in which it is not then so subject.

SECTION 5.04. Expenses. Subject to Section 2.04(c)(ii) all expenses incident to the Company’s performance of or compliance with its obligations under this Article V relating to the issuance of the Warrant Shares will be borne by the Company, including without limitation: (i) all SEC, stock exchange or Financial Industry Regulatory Authority registration and filing fees, (ii) all fees and expenses incurred by the Company in connection with the compliance with state securities or blue sky laws, (iii) all expenses of any Persons incurred by or on behalf of the Company with the prior written consent of the Company in preparing or assisting in preparing, printing and distributing the Common Share Shelf Registration Statement or any other registration statement, prospectus, any amendments or supplements thereto and other documents relating to the performance of and compliance with this Article V, (iv) the fees and disbursements of counsel for the Company and (v) the fees and disbursements of the independent public accountants of the Company.

SECTION 5.05. Delivery of Documents to Holders. The Warrant Agent agrees that concurrently with the issuance of Warrant Shares to any Holder and upon exercise of Warrants by any Holder, the Warrant Agent shall (unless otherwise instructed by the Company) deliver a prospectus relating to the Warrant Shares (a “Prospectus”) to such Holder or such other notice or communication regarding the Warrants or the Warrant Shares as the Company may instruct. The Company shall furnish to the Warrant Agent sufficient copies of such Prospectus or such other notice or communication to satisfy this obligation.

SECTION 7.01. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company in accordance with the express provisions of this Agreement and the Warrant Agent hereby accepts such appointment.

SECTION 7.02. Rights and Duties of Warrant Agent.

(a) Agent for the Company. In acting under this Warrant Agreement and in connection with the Warrant Certificates, the Warrant Agent is acting solely as agent of the Company and does not assume any obligation or relationship or agency or trust for or with any of the holders of Warrant Certificates or beneficial owners of Warrants. All fees and expenses due the Warrant Agent shall be paid to the Warrant Agent by the Company. The Warrant Agent shall have no duty to determine which costs, if any, under this Agreement shall be borne by the Holders or by the Company.

(b) Counsel.
