5.

(a) The Company represents and agrees that, without the prior consent of the Underwriters, it has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Act; each Underwriter, Forward Purchaser and Forward Seller represents and agrees that, without

-24-

the prior consent of the Company and the Underwriters, it has not made and will not make any offer relating to the Shares that would constitute a free writing prospectus required to be filed with the Commission; any such free writing prospectus the use of which has been consented to by the Company and the Underwriters is listed on Schedule III hereto;

(b) The Company has complied and will comply with the requirements of Rule 433 under the Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending; and

(c) The Company agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the Pricing Prospectus or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will give prompt notice thereof to the Underwriters and, if requested by the Underwriters, will prepare and furnish without charge to each Underwriter, Forward Purchaser and Forward Seller an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, however, that this covenant shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with the Underwriter Information.

6. The Company covenants and agrees with the several Underwriters, the Forward Sellers and the Forward Purchasers that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the registration of the Shares under the Act and all other expenses in connection with the preparation, printing, reproduction and filing of the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, any Issuer Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or producing any Agreement among Underwriters, this Agreement, the Transaction Documents, the Blue Sky Memorandum, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Shares; (iii) all expenses in connection with the qualification of the Shares for offering and sale under state securities laws as provided in Section 4(d) hereof, including the reasonable and documented fees and disbursements of a single outside counsel for the Underwriters, the Forward Sellers and the Forward Purchasers in connection with such qualification and in connection with the Blue Sky survey; (iv) all fees and expenses in connection with listing the Shares (including the maximum number of Forward Settlement Shares deliverable to the Forward Purchasers in the aggregate pursuant to the Forward Sale Agreements and any Additional Forward Sale Agreements, whether pursuant to Physical Settlement, Net Share Settlement, as a result of an Acceleration Event (as such terms are defined in the Forward Sale Agreements or such Additional Forward Sale Agreements, as applicable) or otherwise) on the Exchange; (v) the filing fees incident to, and the reasonable fees and disbursements of counsel for the Underwriters, the Forward Sellers and the Forward Purchasers in connection with, any required review by FINRA of the terms of the sale of the Shares; (vi) the cost of preparing the Shares; (vii) the cost and charges of any transfer agent or registrar; and (viii) all other costs and expenses incident to the performance of its obligations hereunder which are not

It is understood, however, that, except as provided in this Section, and Sections 8 and 12 hereof, the Underwriters, the Forward Purchasers and the Forward Sellers will pay all of their own respective costs and expenses, 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.

7. The obligations of the Underwriters, the Forward Purchasers and the Forward Sellers hereunder shall be subject, in their discretion, to the condition that all representations and warranties and other statements of the Company herein are, at and as of the Applicable Time and each Closing Date, true and correct, the condition that the Company shall have performed all of its obligations hereunder theretofore to be performed, and the following additional conditions:

-26-

(e) Neither the Company nor any of its subsidiaries shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Pricing Prospectus any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Pricing Prospectus, and (ii) since the respective dates as of which information is given in the Pricing Prospectus there shall not have been any change in the capital stock or long term debt of the Company or any of its subsidiaries or any change or effect, or any development involving a prospective change or effect, in or affecting (x) the business, properties, general affairs, management, financial position, stockholders’ equity or results of operations of the Company and its subsidiaries, taken as a whole, except as set forth or contemplated in the Pricing Prospectus and the Prospectus, or (y) the ability of the Company to perform its obligations under this Agreement, including the issuance and sale of the Shares, or to consummate the transactions contemplated in the Pricing Prospectus and the Prospectus, the effect of which, in any such case described in clause (i) or (ii), is in your judgment so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares on the terms and in the manner contemplated in the Pricing Prospectus and the Prospectus;

(f) On or after the Applicable Time (i) no downgrading shall have occurred in the rating accorded the Company’s debt securities by any “nationally recognized statistical rating organization”, as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company’s debt securities;

(l) The Forward Sale Agreements shall be in full force and effect at the Initial Closing Date and any Additional Forward Sale Agreements shall be in full force and effect at the related Option Closing Date.

8. (a) The Company will indemnify and hold harmless each Underwriter, Forward Seller and Forward Purchaser against any losses, claims, damages or liabilities, joint or several, to which such Underwriter, Forward Seller or 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 each Underwriter, Forward Seller and Forward Purchaser for any legal or other expenses reasonably incurred by such Underwriter, Forward Seller or 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) Each Underwriter, Forward Seller and 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

-28-

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 an Underwriter, Forward Seller or Forward Purchaser, as applicable, and an applicable document, “Underwriter Information” shall mean the written information furnished to the Company by such Underwriter, Forward Seller or Forward Purchaser expressly for use therein; it being understood and agreed upon that the only such information furnished by any Underwriter, Forward Seller or Forward Purchaser consists of the following information in the Prospectus furnished on behalf of each Underwriter, Forward Seller and 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.

-29-

(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 Underwriters, the Forward Sellers and the Forward Purchasers 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 Underwriters, the Forward Sellers and the Forward Purchasers 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 Underwriters, the Forward Sellers and the Forward Purchasers 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 Underwriters, the Forward Sellers and the Forward Purchasers, 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 Underwriters, the Forward Sellers and the Forward Purchasers 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 Underwriters, the Forward Sellers and the Forward Purchasers agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) 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 any Underwriter, Forward Seller or 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 such Underwriter, Forward Seller or 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 Underwriters’, the Forward Sellers’ and the Forward Purchasers’ respective obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

-30-

(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 each Underwriter, Forward Seller and Forward Purchaser, each person, if any, who controls any Underwriter, Forward Seller or Forward Purchaser within the meaning of the Act and each broker-dealer or other affiliate of any Underwriter, Forward Seller or Forward Purchaser; and the obligations of the Underwriters, the Forward Sellers and the Forward Purchasers under this Section 8 shall be in addition to any liability which the respective Underwriters, Forward Sellers and Forward Purchasers 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.

9. (a) If any Underwriter shall default in its respective obligation to purchase the Shares which it has agreed to purchase hereunder at a Closing Date, you may in your discretion arrange for you or another party or other parties to purchase such Shares on the terms contained herein. If within thirty six hours after such default by any Underwriter you do not arrange for the purchase of such Shares, then the Company shall be entitled to a further period of thirty six hours within which to procure another party or other parties satisfactory to you to purchase such Shares on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Shares, or the Company notifies you that it has so arranged for the purchase of such Shares, you or the Company shall have the right to postpone such Closing Date for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in your opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased does not exceed one eleventh of the aggregate number of all the Shares, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of shares which such Underwriter agreed to purchase hereunder at such Closing Date and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its respective default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one eleventh of the aggregate number of all the Shares, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the applicable Closing Date, the obligations of the Underwriters to purchase and of the Company to issue and sell the Option Shares), shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its respective default.

-31-

10.

(a) If in respect of any Forward Sale Agreement and/or any Additional Forward Sale Agreement, as applicable (i) all the Conditions are not satisfied on or prior to the Initial Closing Date or, in respect of any Additional Forward Sale Agreement entered into pursuant to Section 3(a)(iii) hereof, all the Additional Conditions are not satisfied on or prior to the related Option Closing Date, if any, as the case may be, and the Forward Seller affiliated with the Forward Purchaser party to such Forward Sale Agreement and/or Additional Forward Sale Agreement, as applicable, elects, pursuant to Section 3(b) or 3(c) hereof, as the case may be, not to deliver the Forward Underwritten Shares or the Forward Option Shares, as applicable, otherwise deliverable by such Forward Seller, (ii) in such Forward Purchaser’s commercially reasonable judgment, it or its affiliate is unable to borrow and deliver for sale under this Agreement the full number of shares of Common Stock equal to the number of the Forward Underwritten Shares or the Forward Option Shares, as applicable, to be otherwise borrowed and delivered for sale by its affiliated Forward Seller hereunder or (iii) in such Forward Purchaser’s commercially reasonable judgment, it or its affiliate would incur a Stock Loan Fee (as defined under the relevant Forward Sale Agreement or Additional Forward Sale Agreement, as applicable) of more than a rate equal to 200 basis points per annum to do so, then, in each case, the Company shall issue and sell to the Underwriters, pursuant to Section 3(a)(ii) or 3(a)(iv) hereof, as the case may be, in whole but not in part, an aggregate number of shares of Common Stock equal to the number of Forward Underwritten Shares or Forward Option Shares, as the case may be, that such Forward Seller does not so deliver and sell to the Underwriters. In connection with any such issuance and sale by the Company, the Company or the Underwriters shall have the right to postpone the Initial Closing Date or the related Option Closing Date, as the case may be, for a period not exceeding two business days in order to effect any required changes in any documents or arrangements. The shares of Common Stock sold by the Company to the Underwriters pursuant to this Section 10 in lieu of Forward Underwritten Shares are referred to herein as the “Company Top-Up Underwritten Shares,” and the shares of Common Stock sold by the Company to the Underwriters pursuant to this Section 10(a) in lieu of Forward Option Shares are referred to herein as the “Company Top-Up Option Shares.”

(b) No Forward Purchaser or Forward Seller shall have any liability whatsoever for any Forward Shares underlying its Forward Sale Agreement and/or any Additional Forward Sale Agreement, as applicable, that such Forward Seller does not deliver and sell to the Underwriters or any other party if (i) all of the Conditions are not satisfied on or prior to the Initial Closing Date, in the case of Forward Underwritten Shares, or all of the Additional Conditions are not satisfied on or prior to the related Option Closing Date, in the case of Forward Option Shares, (ii) in such Forward Purchaser’s commercially reasonable judgment, it or its affiliate is unable to borrow and deliver for sale under this Agreement a number of shares of Common Stock equal to the number of the Forward Underwritten Shares or the Forward Option Shares, as applicable, to be otherwise borrowed and delivered for sale by its affiliated Forward Seller hereunder or (iii) in such Forward

-32-

Purchaser’s commercially reasonable judgment, it or its affiliate would incur a Stock Loan Fee (as defined under the relevant Forward Sale Agreement or Additional Forward Sale Agreement, as applicable) of more than a rate equal to 200 basis points per annum to do so, and in the case of (i), (ii) or (iii), such Forward Seller elects, pursuant to Section 3(b) or 3(c) hereof, as the case may be, not to deliver and sell to the Underwriters the Forward Underwritten Shares or the Forward Option Shares, as applicable, (or a portion thereof) otherwise deliverable by such Forward Seller.

11. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, the Forward Sellers and the Forward Purchasers 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 any Underwriter, Forward Seller or 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.

12. If this Agreement shall be terminated pursuant to Section 9 hereof, the Company shall not then be under any liability to any Underwriter, Forward Seller or Forward Purchaser except as provided in Sections 6 and 8 hereof; but, if for any other reason, any Shares are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters, the Forward Sellers and the Forward Purchasers through you for all out of pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters, the Forward Sellers and the Forward Purchasers in making preparations for the purchase, sale and delivery of the Shares, but the Company shall then be under no further liability to any Underwriter except as provided in Sections 6 and 8 hereof.

13. In all dealings hereunder, you shall act on behalf of each of the Underwriters, the Forward Sellers and the Forward Purchasers and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter, the Forward Seller and the Forward Purchaser made or given by you.

In accordance with the requirements of the USA Patriot Act (Title III of Pub.

Opening Transaction

Dear Sir(s):

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 [Goldman Sachs & Co. LLC][Bank of America, N.A.] (“Dealer”) 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”).

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 [Bank of America Corporation]² [Goldman Sachs Group Inc.]³ (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.

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.

(w) Counterparty shall promptly provide notice thereof to Dealer (i) upon the occurrence of any event that would, with the giving of notice, the passage of time or the satisfaction of any condition, constitute an Event of Default, a Potential Event of Default or a Termination Event in respect of which Counterparty is a Defaulting Party or an Affected Party, as the case may be, and (ii) upon announcement of any event that, if consummated, would constitute an Extraordinary Event or Potential Adjustment Event.

(x) Neither Counterparty nor any of its “affiliated purchasers” (as defined by Rule 10b-18 under the Exchange Act (“Rule 10b-18”)) shall take any action that would cause any purchases of Shares by Dealer or any of its Affiliates in connection with any Cash Settlement or Net Share Settlement not to meet the requirements of the safe harbor provided by Rule 10b-18 if such purchases were made by Counterparty. 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.

Such written notice shall be deemed to be a certification by Counterparty to Dealer that such information is true and correct. In addition, Counterparty shall promptly notify Dealer of the earlier to occur of the completion of such transaction and the completion of the vote by target shareholders. Counterparty acknowledges that any such notice may result in a Regulatory Disruption, a Trading Condition or an Early Valuation or may affect the length of any ongoing Unwind Period; accordingly, Counterparty acknowledges that its delivery of such notice must comply with the standards set forth in Section 6(c) above. “Merger Transaction” means any merger, acquisition or similar transaction involving a recapitalization as contemplated by Rule 10b-18(a)(13)(iv) under the Exchange Act.

(a) Dealer acknowledges and agrees that Counterparty’s obligations under the Transaction are not secured by any collateral and that this Confirmation is not intended to convey to Dealer rights with respect to the transactions contemplated hereby that are senior to the claims of common stockholders in any U.S. bankruptcy proceedings of Counterparty; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by Counterparty of its obligations and agreements with respect to this Confirmation or the Agreement; provided further that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transaction other than the Transaction.

(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;

Annex I - 15

(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.

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) [Notwithstanding any provisions of the Agreement, all communications relating to the Transaction or the Agreement shall be transmitted exclusively through Dealer at 200 West Street, New York, New York 10282-2198, Telephone No. (212) 902-1981, Facsimile No. (212) 428-1980/1983]¹³

Annex I - 16

(g) 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.

Annex I - 17

Annex I - 18

(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. If any obligation is unascertained, Y may in good faith estimate that obligation and set-off in respect of the estimate, subject to the relevant party accounting to the other when the obligation is ascertained. Nothing in this Section 14 shall be effective to create a charge or other security interest. This Section 14 shall be without prejudice and in addition to any right of set-off, combination of accounts, lien or other right to which any party is at any time otherwise entitled (whether by operation of law, contract or otherwise).

(b) Notwithstanding anything to the contrary in the foregoing, Dealer agrees not to set off or net amounts due from Counterparty with respect to any Transaction against amounts due from Dealer to Counterparty with respect to contracts or instruments that are not Equity Contracts. “Equity Contract” means any transaction or instrument that does not convey to Dealer rights, or the ability to assert claims, that are senior to the rights and claims of common stockholders in the event of Counterparty’s bankruptcy.

Annex I - 19

Counterparty hereby agrees (a) to check this Confirmation carefully and immediately upon receipt so that errors or discrepancies can be promptly identified and rectified and (b) to confirm that the foregoing (in the exact form provided by Dealer) correctly sets forth the terms of the agreement between Dealer and Counterparty with respect to the Transaction, by manually signing this Confirmation or this page hereof as evidence of agreement to such terms and providing the other information requested herein and immediately returning an executed copy [to Equity Derivatives Documentation Department, Facsimile No.  ###-###-####/83]¹⁷ [via email to the individuals listed in the notice provisions herein].¹⁸

(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).

ANNEX II

[Company Counsel Opinion]

Based on the foregoing and subject to the qualifications and exclusions stated below, we express the following opinions:

C-1 The Registration Statement has become effective under the Act. The Prospectus has been filed pursuant to Rule 424(b) under the Act in the manner and within the time period required by such Rule 424(b) (without reference to Rule 424(b)(8)). Any required filing of any Permitted Free Writing Prospectus listed on Schedule 1 hereto has been made in the manner and within the time period required by Rule 433 under the Act. To our knowledge, no order suspending the effectiveness of the Registration Statement has been issued and no proceeding for that purpose has been instituted or is pending or threatened by the Commission.

C-2 Without independent verification of the factual accuracy, completeness or fairness of any statements made in the Registration Statement and the Prospectus, each of the Registration Statement and the Prospectus (except for the financial statements and financial schedules and other financial or accounting information included therein or omitted therefrom and for management’s report on the Company’s internal control over financial reporting included therein and the Statement of Eligibility of the Trustee on Form T-1 under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), as to which we express no opinion) appear on its face to be appropriately responsive in all material respects with the requirements of the Act.

C-3 The Company is a corporation validly existing under the laws of the State of Wisconsin and has all corporate power and corporate authority necessary to own, lease and operate its properties and to conduct its business as described in the Registration Statement and the Prospectus.

C-4 The Shares conform in all material respects to the description thereof set forth or incorporated by reference in the Registration Statement and the Prospectus.

C-5 The Company has the corporate power to enter into and perform the Underwriting Agreement and the Forward Sale Agreements.

C-6 The Underwriting Agreement and the Forward Sale Agreements have been duly authorized by all necessary corporate action on the part of the Company, and have been duly executed and delivered by the Company.

C-7 The maximum number of Shares initially issuable pursuant to the Forward Sale Agreements have been duly authorized and, when delivered to and paid for by you in accordance with the terms of the Underwriting Agreement and the Forward Sale Agreements, will be validly issued, fully paid and non-assessable.

C-8 No shareholder of the Company or any other person has any preemptive right, right of first refusal or other similar rights to subscribe for or purchase securities of the Company created under or pursuant to the Charter Documents or the Wisconsin Business Corporation Law.

C-9 The Company’s execution, delivery and performance of the Underwriting Agreement and the Forward Sale Agreements do not

(a) breach or result in a default or Repayment Event under any Material Agreement, except for such breaches, defaults or Repayment Events that, according to the Back-Up Certificate would not, individually or in the aggregate, have a Material Adverse Effect;

(b) violate the Charter Documents;

(c) violate the laws that in our experience are typically applicable to agreements similar to the Underwriting Agreement and the Forward Sale Agreements and transactions similar to those contemplated by the Underwriting Agreement and the Forward Sale Agreements, except for such violations that, according to the Back-Up Certificate, would not, individually or in the aggregate, have a Material Adverse Effect;

(d) breach or violate any Material Court Order, except for such breaches or violations that, according to the Back-Up Certificate, would not, individually or in the aggregate, have a Material Adverse Effect; or

(e) violate Regulation T, U or X of the Board of Governors of the Federal Reserve System, provided in rendering this opinion as to such regulations we have assumed that (i) no credit is extended or maintained under the Underwriting Agreement or the Forward Sale Agreements by a U.S. broker-dealer or other “creditor” (as defined in Regulation T) or “foreign branch of a broker-dealer” (within the meaning of Regulation X), and (ii) no proceeds from the sale of the Shares will be used for the immediate purpose of buying or carrying margin stock (within the meaning of Regulation U).

“Material Agreement” means any agreement identified by the Company as a material agreement in its Form 10-K filing with the Commission for the Company’s fiscal year ended December 31, 2017 or in its periodic reports on Form 10-Q for the quarters ending March 31, 2018 or September 30, 2018. “Material Court Order” means the court orders listed on Schedule 2 hereto, which list was provided by the Company in response to our request for a list of all material court orders binding on the Company or its property.

C-10 All consents, approvals, authorizations or other orders of, or registrations or filings on the part of the Company with any United States federal or Wisconsin State governmental or regulatory authority required for the issuance of the Shares have been made or obtained, or will be effective, except for (1) such approvals of the New York Stock Exchange (the “Exchange”) as have been obtained, subject to official notice of issuance, in connection with the listing of the Shares on the Exchange, and (2) such as may be required (and as to which we express no opinion) under applicable state securities laws and regulations or from FINRA in connection with the offer or sale of the Shares.

Annex I - 2

C-11 The statements in the Prospectus under the headings “Description of Common Stock” and “Plan of Distribution” and in the Registration Statement in Item 15, in each case insofar as the statements purport to describe the provisions of documents and laws referred to therein, are accurate in all material respects.

C-12 The Company is not and, immediately upon giving effect to the receipt and application of the proceeds received by the Company from the offering and sale of the Shares as contemplated in the Underwriting Agreement and the Forward Sale Agreements as described in the Prospectus, and as a result of and immediately after giving effect to the transactions contemplated by the Transaction Documents, including, without limitation, the issuance, sale and delivery of shares of Common Stock upon settlement of the Forward Sale Agreements and the application of the proceeds therefrom upon such settlement, in each case, the Company will not be required to register as an “investment company” under the Investment Company Act.

C-13 Without independent verification of the factual accuracy, completeness or fairness of the documents incorporated by reference in the Registration Statement and the Prospectus (other than exhibits thereto and the financial statements and related schedules therein, and other financial and statistical information included therein, as to which we express no opinion), when they became effective or were filed with the Commission, as the case may be, each of such documents appears on its face to be appropriately responsive in all material respects with the requirements of the Act or the Exchange Act, as the case may be, and the rules and regulations of the Commission thereunder.

C-14 Each Forward Sale Agreement is a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms.

D-1 We confirm to you that to our knowledge, except as described in the Registration Statement, the Prospectus and any Permitted Free Writing Prospectus, there is not pending or threatened in writing any action, suit or proceeding to which the Company or any of its consolidated subsidiaries is a party, or to which the property of the Company or any of its consolidated subsidiaries is subject, before or brought by any court or governmental agency or body that, according to the Back-Up Certificate, would reasonably be expected to result in a Material Adverse Effect.

D-2 We have participated in conferences with officers and other representatives of the Company and its independent public accountants and representatives of the Underwriters and their counsel at which the contents of the Registration Statement and the Prospectus and any amendments or supplements thereto were discussed. Although we assume no responsibility for the factual accuracy, completeness or fairness of any statements (other than as set forth in paragraph C-11 above, subject to the assumptions, exclusions and qualifications set forth in this opinion) made in (i) the Registration Statement or any amendment thereto, (ii) the Prospectus or any amendment or supplement thereto, or (iii) the documents incorporated by reference in the Prospectus or any further amendment or supplement thereto, nothing has come to our attention that causes us to believe that:

Annex I - 3

(a) the Registration Statement, at the time the Registration Statement became effective (except for the financial statements and financial schedules and other financial or accounting information included therein or omitted therefrom and for management’s report on the Company’s internal control over financial reporting and the auditor’s report on the effectiveness of the Company’s internal control over financial reporting included therein and the Statement of Eligibility of the Trustee on Form T-1 under the Trust Indenture Act, as to which we make no statement), contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

(b) the Pricing disclosure Package as of the Applicable Time (except for the financial statements and financial schedules and other financial or accounting information included therein or omitted therefrom and for management’s report on the Company’s internal control over financial reporting and the auditor’s report on the effectiveness of the Company’s internal control over financial reporting included therein, as to which we make no statement), contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. or

(c) the Prospectus or any amendment or supplement thereto, as of its date or as amended and supplemented, if applicable, as of the date hereof (except for the financial statements and financial schedules and other financial or accounting information included therein or omitted therefrom and for management’s report on the Company’s internal control over financial reporting and the auditor’s report on the effectiveness of the Company’s internal control over financial reporting included therein, as to which we make no statement), contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.
