including the fees of their counsel, transfer taxes on resale of any of the Shares by them, and any advertising expenses connected with any offers they may make.

8.(a)    The Company will indemnify and hold harmless the Underwriter, the Forward Seller and the Forward Purchaser against any losses, claims, damages or liabilities, joint or several, to which the Underwriter, the Forward Seller or the Forward Purchaser may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any “roadshow” as defined in Rule 433(h) under the Act (a “roadshow”) or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Underwriter, the Forward Seller and the Forward Purchaser for any legal or other expenses reasonably incurred by the Underwriter, the Forward Seller or the Forward Purchaser in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with the Underwriter Information.

(b)The Underwriter, the Forward Seller and the Forward Purchaser will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any roadshow, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any roadshow in reliance upon and in conformity with the Underwriter Information; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred. As used in this Agreement with respect to the Underwriter, the Forward Seller or the Forward Purchaser, as applicable, and an applicable document, “Underwriter Information” shall mean the written information furnished to the Company by the Underwriter, the Forward Seller or the Forward Purchaser expressly for use therein; it being understood and agreed upon that the only such information furnished by the Underwriter, the Forward Seller or the Forward Purchaser consists of the following information in the Prospectus furnished on behalf of the Underwriter, the Forward Seller and the Forward Purchaser: the concession and reallowance figures appearing in the fifth paragraph

under the caption “Underwriting (Conflicts of Interest)”, and the information contained in the second paragraph under the heading “Price Stabilization and Short Positions” under the caption “Underwriting (Conflicts of Interest)”.

(c)Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; provided, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 8 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under the preceding paragraphs of this Section 8. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d)If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter, the Forward Seller and the Forward Purchaser on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriter, the Forward Seller and the Forward Purchaser on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter, the Forward Seller and the Forward Purchaser on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriter, the Forward Seller and the Forward Purchaser, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriter, the Forward Seller and the Forward Purchaser on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Underwriter, the Forward Seller and the Forward Purchaser agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), none of the Underwriter, the Forward Seller or the Forward Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriter, the Forward Seller or the Forward Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriter’s, the Forward Seller’s and the Forward Purchaser’s respective obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e)The obligations of the Company under this Section 8 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each employee, officer and director of the Underwriter, the Forward Seller and the Forward Purchaser, each person, if any, who controls the Underwriter, the Forward Seller or the Forward

Purchaser within the meaning of the Act and each broker-dealer or other affiliate of the Underwriter, the Forward Seller or the Forward Purchaser; and the obligations of the Underwriter, the Forward Seller and the Forward Purchaser under this Section 8 shall be in addition to any liability which the Underwriter, the Forward Seller and the Forward Purchaser may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act.

11.The respective indemnities, agreements, representations, warranties and other statements of the Company and the Underwriter, the Forward Seller and the Forward Purchaser as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of the Underwriter, the Forward Seller or the Forward Purchaser or any controlling person of any such party, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Shares.

The purpose of this communication (this “Confirmation”) is to set forth the terms and conditions of the above-referenced transaction entered into on the Trade Date specified below (the “Transaction”) between Barclays Bank PLC (“Dealer”), through its agent Barclays Capital Inc. (the “Agent”), and Alliant Energy Corporation (“Counterparty”). This communication constitutes a “Confirmation” as referred to in the Agreement specified below. This Confirmation is a confirmation for purposes of Rule 10b-10 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Dealer is not a member of the Securities Investor Protection Corporation. Dealer is authorized by the Prudential Regulation Authority and regulated by the Financial Conduct Authority and the Prudential Regulation Authority.

This Confirmation shall supplement, form a part of and be subject to an agreement (the “Agreement”) in the form of the 1992 ISDA Master Agreement (Multicurrency-Cross Border) (the “ISDA Form”), as published by ISDA, as if Dealer and Counterparty had executed the ISDA Form on the date hereof (but without any Schedule except for (i) the election of Loss and Second Method, New York law (without regard to New York’s choice of laws doctrine other than Title 14 of Article 5 of the New York General Obligations Law) as the governing law and US Dollars (“USD”) as the Termination Currency, (ii) the replacement of the word “third” in the last line of Section 5(a)(i) with the word “first”; and (iii) the election that the “Cross Default” provisions of Section 5(a)(vi) shall apply to Dealer and Counterparty with a “Threshold Amount” of: a) with respect to Dealer, 3% of the Shareholder’s Equity of Dealer with the term “Shareholder’s Equity” defined to mean an amount equal to total assets minus total liabilities, as reflected on its most recent unaudited semi-annual or audited annual financial statements (whichever is more recent); and b) with respect to Counterparty, USD100 million; provided that (x) the words “, or becoming capable at such time of being declared,” shall be deleted from clause (1) thereof and (y) the following language shall be added to the end of such Section 5(a)(vi): “Notwithstanding the foregoing, a default under subsection (2) hereof shall not constitute an Event of Default if (X) the default was caused solely by error or omission of an administrative or operational nature; (Y) funds were available to enable the party to make the payment when due; and (Z) the payment is made within two Local Business Days of such party’s receipt of written notice of its failure to pay;”). All provisions contained in the Agreement are incorporated into and shall govern this Confirmation except as expressly modified below. This Confirmation evidences a complete and binding agreement between Dealer and Counterparty as to the terms of the Transaction and replaces any previous agreement between the parties with respect to the subject matter hereof.

The Transaction hereunder shall be the sole Transaction under the Agreement. If there exists any ISDA Master Agreement between Dealer or any of its Affiliates and Counterparty or any confirmation or other agreement between Dealer or any of its Affiliates and Counterparty pursuant to which an ISDA Master Agreement is deemed to exist between Dealer or any of its Affiliates and Counterparty, then notwithstanding anything to the contrary in such ISDA Master Agreement, such confirmation or agreement or any other agreement to which Dealer or any of its Affiliates are parties, the Transaction shall not be considered a Transaction under, or otherwise governed by, such existing or deemed ISDA Master Agreement. In the event of any inconsistency among the Agreement, this Confirmation and the Equity Definitions, the following will prevail in the order of precedence indicated: (i) this Confirmation; (ii) the Equity Definitions; and (iii) the Agreement.

1 + the Daily Rate * (1/365);

provided that the Forward Price on each Forward Price Reduction Date shall be the Forward Price otherwise in effect on such date minus the Forward Price Reduction Amount for such Forward Price Reduction Date.

(i) Net Share Settlement shall be deemed to be included as an additional settlement method under Section 7.1 of the Equity Definitions;

(ii) Counterparty may elect Cash Settlement or Net Share Settlement only if Counterparty represents and warrants to Dealer in the Settlement Notice containing such election that, as of the date of such Settlement Notice, (A) Counterparty is not aware of any material nonpublic information concerning itself or the Shares, (B) Counterparty is electing the settlement method and designating the First Unwind Date specified in such Settlement Notice in good faith and not as part of a plan or scheme to evade compliance with Rule 10b-5 under the Exchange Act (“Rule 10b-5”) or any other provision of the federal securities laws, (C) Counterparty is not “insolvent” (as such term is defined under Section 101(32) of the U.S. Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”)), (D) Counterparty would be able to purchase a number of Shares equal to the greater of (x) the number of Settlement Shares designated in such Settlement Notice and (y) a number of Shares with a value as of the date of such Settlement Notice equal to the product of (I) such number of Settlement Shares and (II) the applicable Relevant Forward Price for such Cash Settlement or Net Share Settlement in compliance with the laws of Counterparty's jurisdiction of organization, (E) it is not electing Cash Settlement or Net Share Settlement to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for Shares) and (F) such election, and settlement in accordance therewith, does not and will not violate or conflict with any law, regulation or supervisory guidance applicable to Counterparty, or any order or judgment of any

court or other agency of government applicable to it or any of its assets, and any governmental consents that are required to have been obtained by Counterparty with respect to such election or settlement have been obtained and are in full force and effect and all conditions of any such consents have been complied with; and

(iii) Notwithstanding any election to the contrary in any Settlement Notice, Physical Settlement shall be applicable:

(A) to all of the Settlement Shares designated in such Settlement Notice if, at any time from, and including, the date such Settlement Notice is received by Dealer to, and including the related First Unwind Date, (I) the trading price per Share on the Exchange (as determined by Dealer) is below USD[__]² (the “Threshold Price”) or (II) Dealer determines that it would be unable to purchase a number of Shares in the market sufficient to unwind its hedge position in respect of the portion of the Transaction represented by such Settlement Shares and satisfy its delivery obligation hereunder, if any, by the Maturity Date (x) in a manner that (A) would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be subject to the safe harbor provided by Rule 10b-18(b) under the Exchange Act and (B) would not raise material risks under applicable securities laws or (y) due to the lack of sufficient liquidity in the Shares (each, a “Trading Condition”); or

(B) to all or a portion of the Settlement Shares designated in such Settlement Notice if, on any day during the relevant Unwind Period, (I) the trading price per Share on the Exchange (as determined by the Calculation Agent) is below the Threshold Price or (II) Dealer determines that a Trading Condition has occurred, in which case the provisions set forth below in the third paragraph opposite “Early Valuation Date” shall apply as if such day were the Early Valuation Date and (x) for purposes of clause (i) of such paragraph, such day shall be the last Unwind Date of such Unwind Period and the “Unwound Shares” shall be calculated to, and including, such day and (y) for purposes of clause (ii) of such paragraph, the “Remaining Shares” shall be equal to the number of Settlement Shares designated in such Settlement Notice minus the Unwound Shares determined in accordance with clause (x) of this sentence.

If the Early Valuation Date occurs on a date that is not during an Unwind Period, then the Early Valuation Date shall be a Valuation Date for a Physical Settlement, and the number of Settlement Shares for such Settlement shall be the Number of Shares on the Early Valuation Date; provided that Dealer may in its sole discretion permit Counterparty to elect Cash Settlement or Net Share Settlement, or to designate more than one Early Valuation Date, each such Early Valuation Date relating to a number of Settlement Shares designated by Dealer.

If the Early Valuation Date occurs during an Unwind Period, then (i) (A) the last Unwind Date of such Unwind Period shall be deemed to be the Early Valuation Date, (B) a Settlement shall occur in respect of such Unwind Period, and the Settlement Method elected by Counterparty in respect of such Settlement shall apply, and (C) the number of Settlement Shares for such Settlement shall be the number of Unwound Shares for such Unwind Period on the Early Valuation Date, and (ii) (A) the Early Valuation Date shall be a Valuation Date for an additional Physical Settlement (provided that Dealer may in its sole discretion elect that the Settlement Method elected by Counterparty for the Settlement described in clause (i) of this sentence shall apply) and (B) the number of Settlement Shares for such additional Settlement shall be the number of Remaining Shares on the Early Valuation Date; provided that Dealer may designate more than one Early Valuation Date, each such Early Valuation Date relating to a portion of the Remaining Shares designated by Dealer

In addition, in the event of the declaration by Issuer of a Retroactively Declared Extraordinary Dividend, Dealer shall make such adjustment to the relevant number of Settlement Shares, Net Share Settlement Amount or Forward Cash Settlement Amount, as the case may be, to take into account the economic effect of such Retroactively Declared Extraordinary Dividend. “Retroactively Declared Extraordinary Dividend” means any Extraordinary Dividend for which the relevant ex-dividend date occurs concurrently with, or prior to, the declaration by Issuer of such Extraordinary Dividend.

Notwithstanding the foregoing, in the case of a Nationalization or Merger Event, if at the time of the related Relevant Settlement Date the Shares have changed into cash or any other property or the right to receive cash or any other property, the Calculation Agent shall adjust the nature of the Shares as it determines appropriate to account for such change such that the nature of the Shares is consistent with what shareholders receive in such event.

Without limiting the generality of the provisions set forth opposite the caption “Unwind Activities” in Section 2 of this Confirmation, Counterparty acknowledges that it has no right to, and agrees that it will not seek to, control or influence Dealer’s decision to make any “purchases or sales” (within the meaning of Rule 10b5-1(c)(1)(i)(B)(3)) under or in connection with the Transaction, including, without limitation, Dealer’s decision to enter into any hedging transactions.

Without limiting the generality of the foregoing, during any Unwind Period, except with the prior written consent of Dealer, Counterparty will not, and will cause its affiliated purchasers (as defined in Rule 10b-18) not to, directly or indirectly (including, without limitation, by means of a derivative instrument) purchase, offer to purchase, place any bid or limit order that would effect a purchase of, or announce or commence any tender offer relating to, any Shares (or equivalent interest, including a unit of beneficial interest in a trust or limited partnership or a depository share) or any security convertible into or exchangeable for the Shares.

(g)Counterparty shall: (i) prior to the opening of trading in the Shares on any day on which Counterparty makes, or expects to be made, any public announcement (as defined in Rule 165(f) under the Securities Act) of any Merger Transaction, notify Dealer of such public announcement; (ii) promptly notify Dealer following any such announcement that such announcement has been made; (iii) promptly (but in any event prior to the next opening of the regular trading session on the Exchange) provide Dealer with written notice specifying (A) Counterparty’s average daily Rule 10b-18 Purchases (as defined in Rule 10b-18) during the three full calendar months immediately preceding the announcement date for the Merger Transaction that were not effected through Dealer or its affiliates and (B) the number of Shares purchased pursuant to the proviso in Rule 10b-18(b)(4) under the Exchange Act for the three full calendar months preceding such announcement date.

(b)The parties hereto intend for:

(i)    the Transaction to be a “securities contract” as defined in Section 741(7) of the Bankruptcy Code, and the parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(27), 362(o), 546(e), 546(j), 555 and 561 of the Bankruptcy Code;

(ii)    the rights given to Dealer pursuant to “Early Valuation” in Section 2 above to constitute “contractual rights” to cause the liquidation of a “securities contract” and to set off mutual debts and claims in connection with a “securities contract”, as such terms are used in Sections 555 and 362(b)(6) of the Bankruptcy Code;

(iii)    any cash, securities or other property provided as performance assurance, credit support or collateral with respect to the Transaction to constitute “margin payments” and “transfers” under a “securities contract” as defined in the Bankruptcy Code;

(iv)    all payments for, under or in connection with the Transaction, all payments for Shares and the transfer of Shares to constitute “settlement payments” and “transfers” under a “securities contract” as defined in the Bankruptcy Code; and

(v)    any or all obligations that either party has with respect to this Confirmation or the Agreement to constitute property held by or due from such party to margin, guaranty or settle obligations of the other party with respect to the transactions under the Agreement (including the Transaction) or any other agreement between such parties.

(c)Notwithstanding any other provision of the Agreement or this Confirmation, in no event will Counterparty be required to deliver in the aggregate in respect of all Settlement Dates, Net Share Settlement Dates or other dates on which Shares are delivered in respect of any amount owed under this Agreement a number of Shares greater than 2.0 times the Full Number of Shares (as adjusted for stock splits and similar events) (the “Capped Number”). Counterparty represents and warrants to Dealer (which representation and warranty shall be deemed to be repeated on each day that the Transaction is outstanding) that the Capped Number is equal to or less than the number of authorized but unissued Shares that are not reserved for future issuance in connection with transactions in the Shares (other than the Transaction) on the date of the determination of the Capped Number (such Shares, the “Available Shares”). In the event that, as a result of this Section 8(c), Counterparty shall not have delivered the full number of Shares otherwise deliverable (the resulting deficit, the “Deficit Shares”), Counterparty shall be continually obligated to deliver Shares, from time to time until the full number of Deficit Shares have been delivered, when, and to the extent that, (A) Shares are repurchased, acquired or otherwise received by Counterparty or any of its subsidiaries after the Trade Date (whether or not in exchange for cash, fair value or any other consideration), (B) authorized and unissued Shares reserved for issuance in respect of other transactions prior to such date which prior to the relevant date become no longer so reserved and (C) Counterparty additionally authorizes any unissued Shares that are not reserved for other transactions (such events as set forth in clauses (A), (B) and (C) above, collectively, the “Share Issuance Events”). Counterparty shall promptly notify Dealer of the occurrence of any of the Share Issuance Events (including the number of Shares subject to clause (A), (B) or (C) and the corresponding number of Shares to be delivered) and, as promptly as reasonably practicable, deliver such Shares thereafter. Counterparty shall not, until Counterparty’s obligations under the Transaction have been satisfied in full, use any Shares that become available for potential delivery to Dealer as a result of any Share Issuance Event for the settlement or satisfaction of any transaction or obligation other than the Transaction or reserve any such Shares for future issuance for any purpose other than to satisfy Counterparty’s obligations to Dealer under the Transaction.

(d)The parties intend for this Confirmation to constitute a “Contract” as described in the letter dated October 6, 2003 submitted on behalf of Goldman Sachs & Co. to Paula Dubberly of the staff of the Securities and Exchange Commission (the “Staff”) to which the Staff responded in an interpretive letter dated October 9, 2003.

(e)The parties intend for this Transaction (taking into account purchases of Shares in connection with any Cash Settlement or Net Share Settlement) to comply with the requirements of Rule 10b5-1(c)(1)(i)(A) under the Exchange Act and for this Confirmation to constitute a binding contract or instruction satisfying the requirements of 10b5-1(c) and to be interpreted to comply with the requirements of Rule 10b5-1(c).

(f)Counterparty acknowledges that:

(i)during the term of the Transaction, Dealer and its affiliates may buy or sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to establish, adjust or unwind its hedge position with respect to the Transaction;

(ii)Dealer and its affiliates may also be active in the market for the Shares and derivatives linked to the Shares other than in connection with hedging activities in relation to the Transaction, including acting as agent or as principal and for its own account or on behalf of customers;

(iii)Dealer shall make its own determination as to whether, when or in what manner any hedging or market activities in Counterparty’s securities shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the Forward Price and the Settlement Price;

(iv)any market activities of Dealer and its affiliates with respect to the Shares may affect the market price and volatility of the Shares, as well as the Forward Price and the Settlement Price, each in a manner that may be adverse to Counterparty; and

(v)the Transaction is a derivatives transaction; Dealer may purchase or sell Shares for its own account at an average price that may be greater than, or less than, the price received by Counterparty under the terms of the Transaction.

(a)     The parties agree that upon the occurrence of an Event of Default or Termination Event with respect to a party who is the Defaulting Party or the Affected Party (“X”), the other party (“Y”) will have the right (but not be obliged) without prior notice to X or any other person to set-off or apply any obligation of X owed to Y (or any Affiliate of Y) (whether or not matured or contingent and whether or not arising under the Agreement, and regardless of the currency, place of payment or booking office of the obligation) against any obligation of Y (or any Affiliate of Y) owed to X (whether or not matured or contingent and whether or not arising under the Agreement, and regardless of the currency, place of payment or booking office of the obligation). Y will give notice to the other party of any set-off effected under this Section 14. Amounts (or the relevant portion of such amounts) subject to set-off may be converted by Y into the Termination Currency at the rate of exchange at which such party would be able, acting in a reasonable manner and in good faith, to purchase the relevant amount of such currency.

Title:

If Counterparty delivers Unregistered Settlement Shares pursuant to Section 12 above (a “Private Placement Settlement”), then:

(a)all Unregistered Settlement Shares shall be delivered to Dealer (or any affiliate of Dealer designated by Dealer) pursuant to the exemption from the registration requirements of the Securities Act provided by Section 4(a)(2) thereof;

(b)as of or prior to the date of delivery, Dealer and any potential purchaser of any such shares from Dealer (or any affiliate of Dealer designated by Dealer) identified by Dealer shall be afforded a commercially reasonable opportunity to conduct a due diligence investigation with respect to Counterparty customary in scope for private placements of equity securities (including, without limitation, the right to have made available to them for inspection all financial and other records, pertinent corporate documents and other information reasonably requested by them);

(c)as of the date of delivery, Counterparty shall enter into an agreement (a “Private Placement Agreement”) with Dealer (or any affiliate of Dealer designated by Dealer) in connection with the private placement of such shares by Counterparty to Dealer (or any such affiliate) and the private resale of such shares by Dealer (or any such affiliate), substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance commercially reasonably satisfactory to Dealer, which Private Placement Agreement shall include, without limitation, provisions substantially similar to those contained in such private placement purchase agreements relating, without limitation, to the indemnification of, and contribution in connection with the liability of, Dealer and its affiliates and the provision of customary opinions, accountants’ comfort letters and lawyers’ negative assurance letters, and shall provide for the payment by Counterparty of all fees and expenses in connection with such resale, including all fees and expenses of counsel for Dealer, and shall contain representations, warranties, covenants and agreements of Counterparty reasonably necessary or advisable to establish and maintain the availability of an exemption from the registration requirements of the Securities Act for such resales; and

(d)in connection with the private placement of such shares by Counterparty to Dealer (or any such affiliate) and the private resale of such shares by Dealer (or any such affiliate), Counterparty shall, if so requested by Dealer, prepare, in cooperation with Dealer, a private placement memorandum in form and substance reasonably satisfactory to Dealer.

In the case of a Private Placement Settlement, Dealer shall, in its good faith discretion, adjust the amount of Unregistered Settlement Shares to be delivered to Dealer hereunder in a commercially reasonable manner to reflect the fact that such Unregistered Settlement Shares may not be freely returned to securities lenders by Dealer and may only be saleable by Dealer at a discount to reflect the lack of liquidity in Unregistered Settlement Shares.

If Counterparty delivers any Unregistered Settlement Shares in respect of the Transaction, Counterparty agrees that (i) such Shares may be transferred by and among Dealer and its affiliates and (ii) after the minimum “holding period” within the meaning of Rule 144(d) under the Securities Act has elapsed after the applicable Settlement Date, Counterparty shall promptly remove, or cause the transfer agent for the Shares to remove, any legends referring to any transfer restrictions from such Shares upon delivery by Dealer (or such affiliate of Dealer) to Counterparty or such transfer agent of seller’s and broker’s representation letters customarily delivered by Dealer or its affiliates in connection with resales of restricted securities pursuant to Rule 144 under the Securities Act in accordance with such transfer agent’s reasonable requirements, each without any further requirement for the delivery of any certificate, consent, agreement, opinion of counsel, notice or any other document, any transfer tax stamps or payment of any other amount or any other action by Dealer (or such affiliate of Dealer).
