Electing Party: |  | Company

Default Settlement Method: |  | Net Share Settlement

Net Share Settlement: |  | If Net Share Settlement is applicable, then on the relevant Settlement Date, Company shall deliver to Dealer a number of Shares equal to the Share Delivery Quantity for such Settlement Date to the account specified herein free of payment through the Clearance System, and Dealer shall be treated as the holder of record of such Shares at the time of delivery of such Shares or, if earlier, at 5:00 p.m. (New York City time) on such Settlement Date, and Company shall pay to Dealer cash in lieu of any fractional Share based on the Settlement Price on the relevant Valuation Date.

Notwithstanding the foregoing, if (i) any Expiration Date is a Disrupted Day and (ii) the Calculation Agent determines that such Expiration Date shall be an Expiration Date for fewer than the Daily Number of Warrants, as described above, then the Settlement Price for the relevant Valuation Date shall be the volume-weighted average price per Share on such Valuation Date on the Exchange, as determined by the Calculation Agent based on such sources as it deems appropriate using a volume-weighted methodology, for the portion of such Valuation Date for which the Calculation Agent determines there is no Market Disruption Event.

For the avoidance of doubt, the occurrence of an Announcement Event with respect to any transaction or intention shall not preclude the occurrence of a later Announcement Event with respect to such transaction or intention. For purposes of this definition of “Announcement Event,” the remainder of the definition of “Merger Event” in Section 12.1(b) of the Equity Definitions following the definition of “Reverse Merger” therein shall be disregarded.

8

Valid Third Party Entity: |  | In respect of any transaction, any third party that the Calculation Agent determines has a bona fide intent to enter into or consummate such transaction (it being understood and agreed that in determining whether such third party has such a bona fide intent, the Calculation Agent may take into consideration the effect of the relevant announcement by such third party on the Shares and/or options relating to the Shares and, if such effect is material, may deem such third party to have a bona fide intent to enter into or consummate such transaction).

| (b) | Neither the execution and delivery of this Confirmation nor the incurrence or performance of obligations of Company hereunder will conflict with or result in a breach of the certificate of incorporation or by-laws (or any equivalent documents) of Company, or any applicable law or regulation, or any order, writ, injunction or decree of any court or governmental authority or agency, or any agreement or instrument filed as an exhibit to Company’s Annual Report on Form 10-K for the fiscal year ended November 1, 2025, as updated by any subsequent filings, to which Company or any of its subsidiaries is a party or by which Company or any of its subsidiaries is bound or to which Company or any of its subsidiaries is subject, or constitute a default under, or result in the creation of any lien under, any such agreement or instrument, other than, with respect to any such agreement or instrument, any breach, default or lien that would not have a material adverse effect on Company’s ability to perform its obligations under the Transaction.

| (c) | To Company’s knowledge, no consent, approval, authorization, or order of, or filing with, any governmental agency or body or any court is required in connection with the execution, delivery or performance by Company of this Confirmation, except such as have been obtained or made and such as may be required under the Securities Act of 1933, as amended (the “Securities Act”) or state securities laws; provided that Company makes no representation or warranty regarding any such requirement that is applicable generally to the ownership of equity securities by Dealer or any of its affiliates solely as a result of it or any of such affiliates being a financial institution or broker-dealer.

| (d) | A number of Shares equal to the Maximum Number of Shares (as defined below) (the “Warrant Shares”) have been reserved for issuance by all required corporate action of Company. The Warrant Shares have been duly authorized and, when delivered against payment therefor (which may include Net Share Settlement in lieu of cash) and otherwise as contemplated by the terms of the Warrants following the exercise of the Warrants in accordance with the terms and conditions of the Warrants, will be validly issued, fully-paid and non-assessable, and the issuance of the Warrant Shares will not be subject to any preemptive or similar rights, in each case.

| (i) | Company (A) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (B) will exercise independent judgment in evaluating the recommendations of any broker-dealer or its associated persons, unless it has otherwise notified the broker-dealer in writing; and (C) has total assets of at least USD 50 million.

Delivery of such opinion to Dealer shall be a condition precedent for the purpose of Section 2(a)(iii) of the Agreement with respect to each obligation of Dealer under Section 2(a)(i) of the Agreement.

| (b) | Repurchase Notices. Company shall, on or prior to the date one Scheduled Trading Day following any date on which Company obtains actual knowledge that it has effected any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”) if following such repurchase, the number of outstanding Shares on such day, subject to any adjustments provided herein, is (i) less than 87.7 million (in the case of the first such notice) or (ii) thereafter more than 24.1 million less than the number of Shares included in the immediately preceding Repurchase Notice. Company agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all commercially reasonable losses (including losses relating to Dealer’s commercially reasonable hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from commercially reasonable hedging activities or cessation of commercially reasonable hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and commercially reasonable and documented out-of-pocket expenses (including reasonable external attorney’s fees), joint or several, which an Indemnified Person may become subject to, in each case, as a result of Company’s failure to provide Dealer with a Repurchase Notice when and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any commercially reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person as a result of Company’s failure to provide Dealer with a Repurchase Notice in accordance with this paragraph, such Indemnified Person shall promptly notify Company in writing, and Company, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Company may designate in such proceeding and shall pay the commercially reasonable fees and expenses of such counsel related to such proceeding. Company shall not be

14

| liable for any settlement of any such proceeding contemplated by this paragraph that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Company agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Company shall be relieved from liability to the extent that any Indemnified Person fails promptly to notify Company of any action commenced against it in respect of which indemnity may be sought hereunder to the extent Company is materially prejudiced as a result thereof. Company shall not, without the prior written consent of the Indemnified Person, effect any settlement of any such proceeding contemplated by this paragraph that is pending or threatened in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then Company under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in this paragraph are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of the Transaction.

| (c) | Regulation M. Company is not on the Trade Date engaged in a distribution, as such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Company shall not, until the third Scheduled Trading Day immediately following the Trade Date, engage in such a distribution, in either case, of any securities of Company, other than a distribution meeting the requirements of the exception set forth in Rules 101(b) and 102(b) of Regulation M.

| (d) | No Manipulation. Company is not entering into the Transaction to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the Exchange Act.

| (e) | Transfer or Assignment. Company may not transfer any of its rights or obligations under the Transaction without the prior written consent of Dealer. Dealer may, without Company’s consent, transfer or assign all or any part of its rights or obligations under the Transaction to any affiliate of Dealer or any internationally recognized investment bank; provided that, in each case, as a result of such transfer or assignment, (i) as of the date of such transfer or assignment, Company will not be required to pay the transferee or assignee on any payment date or settlement date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Company would have been required to pay to Dealer in the absence of such transfer or assignment, (ii) such transferee makes such Payee Tax Representations and provides such tax documentation as may be reasonably requested by Company to permit Company to determine that such transfer or assignment complies with clause (i) of this sentence, (iii) no Event of Default, Potential Event of Default or Termination Event will occur as a result of such transfer and assignment and (iv) Dealer shall be responsible for all reasonable costs and expenses, including reasonable counsel fees, incurred by Company in connection with such transfer or assignment. If at any time at which (A) the Section 16 Percentage exceeds 9.0%, (B) the Warrant Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “Excess Ownership Position”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Warrants in accordance with the preceding sentence on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “Terminated Portion”), such that following such partial termination no Excess Ownership Position exists. In the event that Dealer so designates an Early Termination Date with respect to a Terminated Portion, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date

15

| had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Warrants equal to the number of Warrants underlying the Terminated Portion, (2) Company were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, Company shall be able to settle any corresponding obligation in cash or Shares (or the Share Termination Alternative, as the case may be), in its discretion in accordance with the provisions of Section 9(j)). The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and any of its affiliates or any other person subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. The “Warrant Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Warrants and the Warrant Entitlement and (2) the aggregate number of Shares underlying any other warrants purchased by Dealer from Company, and (B) the denominator of which is the number of Shares outstanding. The “Share Amount” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Company that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares that, in Dealer’s reasonable judgment based on advice of counsel, could give rise to reporting or registration obligations (except for any filing requirements on Form 13F, Schedule 13D or Schedule 13G under the Exchange Act, in each case, as in effect on the Trade Date) or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding. Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Company, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Company to the extent of any such performance. Dealer shall provide Company with written notice of any transfer or assignment on, or as promptly as practicable after, the date of such transfer or assignment.

| (f) | Dividends. If at any time during the period from and including the Effective Date, to and including the last Expiration Date, an ex-dividend date for a cash dividend occurs with respect to the Shares, then the Calculation Agent will adjust any of the Strike Price, Number of Warrants, Daily Number of Warrants and/or any other variable relevant to the exercise, settlement or payment of the Transaction to preserve the fair value of the Warrants to Dealer after taking into account such dividend.

| (g) | [QFC Stay Rules. The parties agree that (i) to the extent that prior to the date hereof both parties have adhered to the 2018 ISDA U.S. Resolution Stay Protocol (the “Protocol”), the terms of the Protocol are incorporated into and form a part of this Confirmation, and for such purposes this Confirmation shall be deemed a Protocol Covered Agreement and each party shall be deemed to have the same status as Regulated Entity and/or Adhering Party as applicable to it under the Protocol; (ii) to the extent that prior to the date hereof the parties have executed a separate agreement the effect of which is to amend the qualified financial contracts between them to conform with the requirements of the QFC Stay Rules (the “Bilateral Agreement”), the terms of the Bilateral

In the event of any inconsistencies between this Confirmation and the terms of the Protocol, the Bilateral Agreement or the Bilateral Terms (each, the “QFC Stay Terms”), as applicable, the QFC Stay Terms will govern. Terms used in this paragraph without definition shall have the meanings assigned to them under the QFC Stay Rules. For purposes of this paragraph, references to “this Confirmation” include any related credit enhancements entered into between the parties or provided by one to the other. “QFC Stay Rules” means the regulations codified at 12 C.F.R. 252.2, 252.81–8, 12 C.F.R. 382.1-7 and 12 C.F.R. 47.1-8, which, subject to limited exceptions, require an express recognition of the stay-and-transfer powers of the FDIC under the Federal Deposit Insurance Act and the Orderly Liquidation Authority under Title II of the Dodd Frank Wall Street Reform and Consumer Protection Act and the override of default rights related directly or indirectly to the entry of an affiliate into certain insolvency proceedings and any restrictions on the transfer of any covered affiliate credit enhancements.]

| (A) | Except in connection with transactions described in clause (B) below, a “person” or “group” within the meaning of Section 13(d) of the Exchange Act, other than Company, its direct or indirect wholly owned subsidiaries and its and their employee benefit plans, has become and files a Schedule TO (or any successor schedule, form or report) or any schedule, form or report under the Exchange Act that discloses that such person or group has become the direct or indirect “beneficial owner,” as defined in Rule 13d-3 under the Exchange Act, of the Shares representing more than 50% of the voting power of the Shares, unless such

18

| beneficial ownership arises solely as a result of a revocable proxy delivered in response to a public proxy or consent solicitation made pursuant to the applicable rules and regulations under the Exchange Act and is not also then reportable on Schedule 13D or Schedule 13G (or any successor schedule) under the Exchange Act regardless of whether such a filing has actually been made; provided that no person or group shall be deemed to be the beneficial owner of any securities tendered pursuant to a tender or exchange offer made by or on behalf of such “person” or “group” until such tendered securities are accepted for purchase or exchange under such offer.

| (B) | Consummation of (I) any recapitalization, reclassification or change of the Shares (other than a change to par value, or from par value to no par value, or changes resulting from a subdivision or combination) as a result of which the Shares would be converted into, or exchanged for, stock, other securities, other property or assets, (II) any share exchange, consolidation or merger of Company pursuant to which the Shares will be converted into or exchanged for cash, securities or other property or assets or (III) any sale, lease or other transfer in one transaction or a series of transactions of all or substantially all of the consolidated assets of Company and its subsidiaries, taken as a whole, to any person other than one or more of Company’s direct or indirect wholly owned subsidiaries. Notwithstanding the foregoing, any transaction or transactions set forth in this clause (B) shall not constitute an Additional Termination Event if (x) at least 90% of the consideration received or to be received by holders of the Shares, excluding cash payments for fractional Shares and cash payments made in respect of dissenters’ appraisal rights, in connection with such transaction or transactions consists of shares of common stock that are listed or quoted on any of The New York Stock Exchange, The Nasdaq Global Select Market or The Nasdaq Global Market (or any of their respective successors) or will be so listed or quoted when issued or exchanged in connection with such transaction or transactions, and (y) as a result of such transaction or transactions, the Shares will consist of such consideration, excluding cash payments for fractional Shares and cash payments made in respect of dissenters’ appraisal rights.

| (C) | Default by Company or any of its significant subsidiaries with respect to any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any indebtedness for money borrowed in excess of $125,000,000 (or its foreign currency equivalent) in the aggregate of Company and/or any such significant subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable prior to its stated maturity date or (ii) constituting a failure to pay the principal of any such debt when due and payable (after the expiration of all applicable grace periods) at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, and in the cases of clauses (i) and (ii), such acceleration shall not have been rescinded or annulled, such failure to pay or default shall not have been cured or waived or such indebtedness is not paid or discharged, as the case may be, within 30 days after written notice to Company.

forth in Article 1, Rule 1-02(w) of Regulation S-X (or any successor rule) as in effect on the relevant date of determination, such subsidiary shall not be deemed to be a “significant subsidiary” under this Confirmation irrespective of whether such subsidiary has greater than $35,000,000 in income from continuing operations as described in the immediately preceding sentence.

| (i) | No Collateral or Setoff. Notwithstanding any provision of the Agreement or any other agreement between the parties to the contrary, the obligations of Company hereunder are not secured by any collateral. Both parties waive any rights to set-off or netting, including in any bankruptcy proceedings of Company, amounts due either party with respect to any Transaction hereunder against amounts due to either party from the other party under any other agreement between the parties.

| (j) | Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events.

If (a) an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to the Transaction or (b) the Transaction is cancelled or terminated upon the occurrence of an Extraordinary Event (except as a result of (i) a Nationalization, Insolvency or Merger Event in which the consideration to be paid to all holders of Shares consists solely of cash, (ii) a Merger Event or Tender Offer that is within Company’s control, or (iii) an Event of Default in which Company is the Defaulting Party or a Termination Event in which Company is the Affected Party other than an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in Section 5(b) of the Agreement, in each case that resulted from an event or events outside Company’s control), and if Company would owe any amount to Dealer pursuant to Section 6(d)(ii) of the Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “Payment Obligation”), then Company shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Company gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. (New York City time) on the Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable, of its election that the Share Termination Alternative shall not apply and (b) Company acknowledges to Dealer, as of the date of such election, its responsibilities under applicable securities laws, and in particular Section 9 and Section 10(b) of the Exchange Act and the rules and regulations thereunder, in connection with such election, in which case the provisions of Section 12.7 or Section 12.9 of the Equity Definitions, or the provisions of Section 6(d)(ii) of the Agreement, as the case may be, shall apply.

Share Termination Alternative: |  | If applicable, Company shall deliver to Dealer the Share Termination Delivery Property on the date (the “Share Termination Payment Date”) on which the Payment Obligation would otherwise be due pursuant to Section 12.7 or Section 12.9 of the Equity Definitions or Section 6(d)(ii) of the Agreement, as applicable, subject to Section 9(k)(i) below, in satisfaction, subject to Section 9(k)(ii) below, of the relevant Payment Obligation, in the manner reasonably requested by Dealer free of payment.

20

Share Termination Delivery Property: |  | A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the relevant Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the amount of Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price (without giving effect to any discount pursuant to Section 9(k)(i)).
Share Termination Unit Price: |  | The value to Dealer of property contained in one Share Termination Delivery Unit on the date such Share Termination Delivery Units are to be delivered as Share Termination Delivery Property, as determined by the Calculation Agent in its discretion by commercially reasonable means. In the case of a Private Placement of Share Termination Delivery Units that are Restricted Shares (as defined below), as set forth in Section 9(k)(i) below, the Share Termination Unit Price shall be determined by the discounted price applicable to such Share Termination Delivery Units. In the case of a Registration Settlement of Share Termination Delivery Units that are Restricted Shares (as defined below) as set forth in Section 9(k)(ii) below, notwithstanding the foregoing, the Share Termination Unit Price shall be the Settlement Price on the Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable. The Calculation Agent shall notify Company of the Share Termination Unit Price at the time of notification of such Payment Obligation to Company or, if applicable, at the time the discounted price applicable to the relevant Share Termination Units is determined pursuant to Section 9(k)(i).
Share Termination Delivery Unit: |  | One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “Exchange Property”), a unit consisting of the type and amount of Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event. If such Nationalization, Insolvency or Merger Event involves a choice of Exchange Property to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash.
Failure to Deliver: |  | Inapplicable

21

Other applicable provisions: |  | If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9, 9.11 and 9.12 (as modified above) of the Equity Definitions will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that the Share Termination Alternative is applicable to the Transaction.

| (k) | Registration/Private Placement Procedures. If, in the good faith reasonable opinion of Dealer and based on the advice of counsel, following any delivery of Shares or Share Termination Delivery Property to Dealer hereunder, such Shares or Share Termination Delivery Property would be in the hands of Dealer subject to any applicable restrictions with respect to any registration or qualification requirement or prospectus delivery requirement for such Shares or Share Termination Delivery Property pursuant to any applicable federal or state securities law (including, without limitation, any such requirement arising under Section 5 of the Securities Act as a result of such Shares or Share Termination Delivery Property being “restricted securities”, as such term is defined in Rule 144 under the Securities Act, or as a result of the sale of such Shares or Share Termination Delivery Property being subject to paragraph (c) of Rule 145 under the Securities Act) (such Shares or Share Termination Delivery Property, “Restricted Shares”), then delivery of such Restricted Shares shall be effected pursuant to either clause (i) or (ii) below at the election of Company, unless Dealer waives the need for registration/private placement procedures set forth in (i) and (ii) below. Notwithstanding the foregoing, solely in respect of any Daily Number of Warrants exercised or deemed exercised on any Expiration Date, if Dealer notifies Company of the need for registration or private placement procedures set forth in this Section 9(k), then Company shall elect, prior to the later of (x) the first Settlement Date for the first applicable Expiration Date and (y) the third Scheduled Trading Day following the date of such notification, a Private Placement Settlement or Registration Settlement for all deliveries of Restricted Shares for all such Expiration Dates which election shall be applicable to all remaining Settlement Dates for such Warrants and the procedures in clause (i) or clause (ii) below shall apply for all such delivered Restricted Shares on an aggregate basis commencing after the final Settlement Date for such Warrants. The Calculation Agent shall make commercially reasonable adjustments to settlement terms and provisions under this Confirmation to reflect a single Private Placement or Registration Settlement for such aggregate Restricted Shares delivered hereunder.

| (i) | If Company elects to settle the Transaction pursuant to this clause (i) (a “Private Placement Settlement”), then delivery of Restricted Shares by Company shall be effected in accordance with private placement procedures with respect to such Restricted Shares customary for private placements of equity securities of a substantially similar size reasonably acceptable to Dealer; provided that Company may not elect a Private Placement Settlement if, on the date of its election, it has taken, or caused to be taken, any action that would make unavailable either the exemption pursuant to Section 4(a)(2) of the Securities Act for the sale by Company to Dealer (or any affiliate designated by Dealer) of the Restricted Shares or the exemption pursuant to Section 4(a)(1) or Section 4(a)(3) of the Securities Act for resales of the Restricted Shares by Dealer (or any such affiliate of Dealer). The Private Placement Settlement of such Restricted Shares shall include customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Dealer, due diligence rights (for Dealer or any designated buyer of the Restricted Shares by Dealer), opinions and certificates, and such other documentation as is customary for private placement agreements of equity securities of a substantially similar size, all reasonably acceptable to Dealer. In the case of a Private Placement Settlement, Dealer shall determine the appropriate discount to the Share Termination Unit Price (in the case of settlement of Share Termination Delivery Units pursuant to Section 9(j) above) or

22

| premium to any Settlement Price (in the case of settlement of Shares pursuant to Section 2 above) applicable to such Restricted Shares in a commercially reasonable manner and appropriately adjust the number of such Restricted Shares to be delivered to Dealer hereunder. Notwithstanding anything to the contrary in the Agreement or this Confirmation, the date of delivery of such Restricted Shares shall be the Exchange Business Day following notice by Dealer to Company of such applicable discount or premium, as the case may be, and the number of Restricted Shares to be delivered pursuant to this clause (i). For the avoidance of doubt, delivery of Restricted Shares shall be due as set forth in the previous sentence and not be due on the Share Termination Payment Date (in the case of settlement of Share Termination Delivery Units pursuant to Section 9(j) above) or on the Settlement Date for such Restricted Shares (in the case of settlement in Shares pursuant to Section 2 above).

| (ii) | If Company elects to settle the Transaction pursuant to this clause (ii) (a “Registration Settlement”), then Company shall promptly (but in any event no later than the beginning of the Resale Period) file and use its reasonable best efforts to make effective under the Securities Act a registration statement or supplement or amend an outstanding registration statement in form and substance reasonably satisfactory to Dealer, to cover the resale of such Restricted Shares in accordance with customary resale registration procedures for registered secondary offerings of a substantially similar size, including covenants, conditions, representations, underwriting discounts (if applicable), commissions (if applicable), indemnities due diligence rights, opinions and certificates, and such other documentation as is customary for equity resale underwriting agreements for registered secondary offerings of a substantially similar size and comparably sized companies, all reasonably acceptable to Dealer. If Dealer, in its sole reasonable discretion, is not satisfied with such procedures and documentation Private Placement Settlement shall apply. If Dealer is satisfied with such procedures and documentation, it shall sell the Restricted Shares pursuant to such registration statement during a period (the “Resale Period”) commencing on the Exchange Business Day following delivery of such Restricted Shares (which, for the avoidance of doubt, shall be (x) the Share Termination Payment Date in case of settlement in Share Termination Delivery Units pursuant to Section 9(j) above or (y) the Settlement Date in respect of the final Expiration Date for all Daily Number of Warrants) and ending on the Exchange Business Day on which Dealer completes the sale of all Restricted Shares or, in the case of settlement of Share Termination Delivery Units, a sufficient number of Restricted Shares so that the realized net proceeds of such sales equals or exceeds the Payment Obligation (as defined above).

The Resale Period shall continue to enable the sale of the Make-whole Shares. If Company elects to pay the Additional Amount in Shares, the requirements and provisions for Registration Settlement shall apply. This provision shall be applied successively until the Additional Amount is equal to zero. In no event shall Company deliver a number of Restricted Shares greater than the Maximum Number of Shares.

| (iii) | Without limiting the generality of the foregoing, Company agrees that (A) any Restricted Shares delivered to Dealer may be transferred by and among Dealer and its affiliates and Company shall effect such transfer without any further action by Dealer and (B) after the period of 6 months from the Trade Date (or 1 year from the Trade Date if, at such time, informational requirements of Rule 144(c) under the Securities Act are not satisfied with respect to Company) has elapsed in respect of any Restricted Shares delivered to Dealer, Company shall promptly remove, or cause the transfer agent for such Restricted Shares to remove, any legends referring to any such restrictions or requirements from such Restricted

Notwithstanding anything to the contrary herein, to the extent the provisions of Rule 144 of the Securities Act or any successor rule are amended, or the applicable interpretation thereof by the Securities and Exchange Commission or any court change after the Trade Date, the agreements of Company herein shall be deemed modified to the extent necessary, in the opinion of outside counsel of Company, to comply with Rule 144 of the Securities Act, as in effect at the time of delivery of the relevant Shares or Share Termination Delivery Property.

If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result of this provision, Company’s obligation to make such delivery shall not be extinguished and Company shall make such delivery as promptly as practicable after, but in no event later than one Business Day after, Dealer gives notice to Company that, after such delivery, (i) the Section 16 Percentage would not exceed 4.9%, and (ii) the Share Amount would not exceed the Applicable Share Limit.

| (m) | Share Deliveries. Notwithstanding anything to the contrary herein, Company agrees that any delivery of Shares or Share Termination Delivery Property shall be effected by book-entry transfer through the facilities of DTC, or any successor depositary, if at the time of delivery, such class of Shares or class of Share Termination Delivery Property is in book-entry form at DTC or such successor depositary.
