NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements set forth herein, and subject to the conditions set forth herein, and each intending to be legally bound hereby, the Parties agree as follows:

ARTICLE I

THE MERGER

Section 1.01 The Merger. At the Effective Time, upon the terms and subject to the conditions set forth herein, and in accordance with the relevant provisions of the MBCA and the DLLCA, Merger Sub shall be merged with and into the Company, and the separate existence of Merger Sub shall thereupon cease. The Company shall continue its existence under the Laws of the State of Minnesota as the surviving corporation in the Merger (sometimes referred to herein as the “Surviving Corporation”) and a subsidiary of Parent.

Section 1.02 The Effective Time. Upon the terms and subject to the conditions set forth herein, as soon as practicable on the Closing Date, (a) the Company shall deliver to and file with the Secretary of State of the State of Minnesota articles of merger with respect to the Merger, in such form as is required by, and executed in accordance with, the relevant provisions of the MBCA (the “Articles of Merger”), (b) the Company shall file with the Secretary of State of the State of Delaware a certificate of merger with respect to the Merger, in such form as is required by, and executed in accordance with, the relevant provisions of the DLLCA (the “Certificate of Merger”) and (c) the Parties hereto shall make all other filings, recordings or publications required under the MBCA and the DLLCA in connection with the Merger.

Section 1.03 The Closing. Unless this Agreement has been terminated in accordance with Section 8.01, the consummation of the Merger (the “Closing”) shall take place at the offices of the Company, ▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (or remotely via the electronic exchange of executed documents) at 9:00 a.m. (New York City time) on the fifth Business Day following the satisfaction or waiver (to the extent such waiver is permitted by Law) of the conditions to the Closing set forth in Article VII (except for those conditions to the Closing that by their nature are to be satisfied at the Closing but subject to the satisfaction or waiver of such conditions), unless another time, date or place is mutually agreed to in writing by the Parties. Notwithstanding anything to the contrary in Section 8.01(b)(i), if the conditions to the Closing set forth in Article VII (except for those conditions to the Closing that by their nature are to be satisfied at the Closing but subject to the satisfaction or waiver of such conditions) have been satisfied or waived on a date that is prior to the End Date but the Closing Date would occur after the End Date, the End Date shall be automatically extended such that it occurs on the day

Exhibit 2.1

immediately following the five (5) Business Day period described in the preceding sentence. The date on which the Closing occurs is referred to herein as the “Closing Date.”

Section 1.04 Effects of the Merger. The Merger shall have the effects specified herein and in the applicable provisions of the MBCA and the DLLCA. Without limiting the foregoing, from and after the Effective Time, the Surviving Corporation shall possess all of the properties, rights, privileges, powers and franchises of the Company and Merger Sub, and all of the claims, obligations, liabilities, debts and duties of the Company and Merger Sub shall become the claims, obligations, liabilities, debts and duties of the Surviving Corporation. As a result of the Merger, all classes and series of the capital stock of the Company and all classes and series of the capital stock of Merger Sub, will be converted or cancelled in the manner provided in Article II.

Section 1.05 Surviving Corporation Organizational Documents. As of the Effective Time, the articles of incorporation and bylaws of the Surviving Corporation, as in effect immediately prior to the Effective Time, shall be amended and restated as of the Effective Time to be in the form of the articles of incorporation attached as Exhibit B and the bylaws attached as Exhibit C, respectively, until thereafter amended as provided therein and in accordance with applicable Law.

Section 1.06 Surviving Corporation Directors and Officers. As of the Effective Time, (a) the managers of Merger Sub as of immediately prior to the Effective Time shall be the directors of the Surviving Corporation to serve until their respective successors are duly elected or appointed and qualified (including in accordance with Section 6.06) or until their earlier death, resignation or removal in accordance with the articles of incorporation and bylaws of the Surviving Corporation; provided, however, that within one (1) Business Day immediately following the Effective Time, Parent shall take, or shall cause Parent and the Surviving Corporation to take, all such actions as are necessary to cause the board of directors of the Surviving Corporation to consist of persons determined in accordance with the requirements set forth in Section 6.06, to serve until their respective successors are duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the articles of incorporation and bylaws of the Surviving Corporation and (b) the officers of the Company as of immediately prior to the Effective Time shall be the officers of the Surviving Corporation, in each case until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the articles of incorporation and bylaws of the Surviving Corporation.

Exhibit 2.1

ARTICLE II

MERGER CONSIDERATION; EXCHANGE OF CERTIFICATES AND BOOK-ENTRY SHARES

Section 2.01 Merger Consideration. At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof:

(a) Conversion of Company Common Stock. Subject to Section 2.03 and Section 2.04, and except as otherwise provided by Section 2.01(b) and Section 2.04(b), each share of common stock, no par value, of the Company (“Company Common Stock”) issued and outstanding immediately prior to the Effective Time, other than the AccommodationCo Share, if any, and the Dissenting Shares in accordance with Section 2.01(g) and Section 2.05, shall automatically be converted into, and shall thereafter represent solely, the right to receive cash in the amount of $67.00, without interest (the “Merger Consideration”).

(b) Equitable Adjustment. If at any time during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of Company Common Stock (or any other securities convertible therefor or exchangeable thereto) shall occur as a result of any reclassification, recapitalization, stock split (including a reverse stock split), combination, subdivision, exchange or readjustment of shares, or any stock dividend or stock distribution with a record date during such period, or any similar event, in each case, other than pursuant to the transactions contemplated by this Agreement, the Merger Consideration shall be equitably adjusted to provide to the holders of shares of Company Common Stock the same economic effect as contemplated by this Agreement prior to such action; provided, however, that nothing in this Section 2.01(b) shall be deemed construed to supersede or in any way limit Section 5.01 or to authorize or permit the Company to effect any such change that is not otherwise specifically authorized or permitted by this Agreement.

(c) Outstanding Units of Parent. Each membership interest unit of Parent issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and unaffected by the Merger.

(d) Outstanding Units of Merger Sub. Each membership interest unit of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one share of Class A stock (“Class A Stock”) of the Surviving Corporation and shall constitute the only outstanding shares of Class A Stock of the Surviving Corporation.

(e) Outstanding AccommodationCo Share. The AccommodationCo Share, if any, shall be converted into and become one share of Class B stock (“Class B Stock”) of the Surviving Corporation and shall constitute the only outstanding share of Class B Stock of the Surviving Corporation.

(f) Outstanding Preferred Stock. Each share of Preferred Stock issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and unaffected by the Merger.

Exhibit 2.1

(g) Dissenting Shares. At the Effective Time, each Dissenting Share shall cease to be outstanding, be canceled without payment of any consideration therefor and shall cease to exist, subject to any rights the holder thereof may have pursuant to Section 2.05 and the MBCA.

Section 2.02 Rights as Shareholders. At the Effective Time, except as set forth in Section 2.05, holders of shares of Company Common Stock (except for the holder of the AccommodationCo Share, if any) shall cease to be, and shall have no rights as, shareholders of the Company, other than (a) to receive, without interest, any dividend or other distribution with respect to such shares of Company Common Stock with a record date occurring prior to the Effective Time and (b) to receive the consideration provided under this Article II upon, in the case of any shares that are certificated, surrender of such Certificate or Book-Entry Share in accordance with Section 2.03.

Section 2.03 Exchange and Payment Procedures.

(a) Exchange Agent. Prior to the Closing Date, Parent shall appoint a bank or trust company to act as paying and exchange agent reasonably acceptable to the Company (the “Exchange Agent”) for the purpose of exchanging shares of Company Common Stock for the Merger Consideration in accordance with Section 2.01(a). At or prior to the Effective Time, Parent shall deposit or cause to be deposited with the Exchange Agent, in trust for the benefit of the holders of shares of Company Common Stock contemplated by Section 2.01(a), an aggregate amount of cash sufficient to deliver the aggregate amount of the Merger Consideration (which, for the avoidance of doubt, shall not include any amounts due under Section 2.04). All such cash shall hereinafter be referred to as the “Exchange Fund.”

(b) Payment Procedures

(i) Promptly after the Effective Time (but no later than three (3) Business Days after the Effective Time), the Exchange Agent will mail to each holder of record of a certificate representing outstanding shares of Company Common Stock immediately prior to the Effective Time (a “Certificate”) whose shares were converted into the right to receive the Merger Consideration pursuant to Section 2.01(a):

(1) a letter of transmittal, which shall specify that delivery shall be effected, and that risk of loss and title to Certificates held by such holder will pass, only upon proper delivery of such Certificates to the Exchange Agent in accordance with the procedures set forth in the letter of transmittal and which shall be in form and substance reasonably satisfactory to Parent and the Company; and

(2) instructions for use in effecting the surrender of such Certificates in exchange for the Merger Consideration with respect to such shares; provided, however, with respect to each holder of Certificates whose shares cease to be Dissenting Shares following the Effective Time pursuant to Section 2.05, Parent shall instruct the Exchange Agent promptly after the date on which Parent becomes aware that such Dissenting Shares have ceased to be Dissenting Shares to mail to such holder the letter of transmittal and instructions referred to above with respect to such shares.

Exhibit 2.1

(ii) Upon surrender to, and acceptance in accordance with Section 2.03(b)(iii) by, the Exchange Agent of a Certificate (or affidavits of loss in lieu thereof under Section 2.03(g)) together with the letter of transmittal, if applicable, duly completed and validly executed in accordance with the instructions thereto, the holder thereof will be entitled to the Merger Consideration payable in respect of the number of shares of Company Common Stock formerly represented by such Certificate surrendered under this Agreement.

(iii) The Exchange Agent will accept Certificates upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange of the Certificates in accordance with customary exchange practices.

(iv) Notwithstanding anything herein to the contrary, any holder of uncertificated shares of Company Common Stock (including any shares held pursuant to the Company Benefit Plans) represented by book entry immediately prior to the Effective Time and whose shares were converted into the right to receive the Merger Consideration (“Book-Entry Shares”), shall not be required to deliver a Certificate or an executed letter of transmittal to the Exchange Agent. In lieu thereof, each holder of record of one (1) or more Book-Entry Shares that are converted into the right to receive the Merger Consideration shall automatically upon the Effective Time be entitled to receive, and Parent shall cause the Exchange Agent to pay and deliver as promptly as reasonably practicable after the Effective Time, cash in an amount equal to the Merger Consideration multiplied by the number of uncertificated shares of Company Common Stock previously represented by such Book-Entry Shares. No interest shall be paid or accrue on any cash payable upon conversion of any Book-Entry Shares.

(v) From and after the Effective Time, no further transfers may be made on the records of the Company or its transfer agent of Certificates or Book-Entry Shares, and if any Certificate or Book-Entry Share is presented to the Company for transfer, such Certificate or Book-Entry Share shall be canceled against delivery of the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificate or Book-Entry Share.

(vi) If any Merger Consideration is to be remitted to a name other than that in which a Certificate or Book-Entry Share is registered, no Merger Consideration may be paid in exchange for such surrendered Certificate or Book-Entry Share unless:

(1) either (A) the Certificate so surrendered is properly endorsed, with signature guaranteed, or otherwise in proper form for transfer or (B) the Book-Entry Share is properly transferred; and

(2) the Person requesting such payment shall (A) pay any transfer or other Taxes required by reason of the payment to a Person other than the registered holder of the Certificate or Book-Entry Share or (B) establish to the satisfaction of the Exchange Agent that such Taxes have been paid or are not payable.

Exhibit 2.1

(vii) At any time after the Effective Time until surrendered as contemplated by this Section 2.03, each Certificate or Book-Entry Share shall be deemed to represent only the right to receive upon such surrender the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificate or Book-Entry Share as contemplated by Section 2.01(a). No interest will be paid or accrued for the benefit of holders of Certificates or Book-Entry Shares on the Merger Consideration payable in respect of the shares of Company Common Stock represented by Certificates or Book-Entry Shares.

(i) At the Effective Time, each holder of a Certificate, and each holder of Book-Entry Shares, will cease to have any rights with respect to such shares of Company Common Stock, except, to the extent provided by Section 2.02, for the right to receive the Merger Consideration payable in respect of the shares of Company Common Stock formerly represented by such Certificate or Book-Entry Shares upon surrender of such Certificate or Book-Entry Share in accordance with Section 2.03(b).

(ii) The Merger Consideration paid upon the surrender or exchange of Certificates or Book-Entry Shares in accordance with this Section 2.03 will be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Company Common Stock formerly represented by such Certificates or Book-Entry Shares.

(d) Termination of Exchange Fund. The Exchange Agent will deliver to the Surviving Corporation, upon the Surviving Corporation’s demand, any portion of the Exchange Fund (including any interest and other income received by the Exchange Agent in respect of all such funds) which remains undistributed to the former holders of Certificates or Book-Entry Shares upon expiration of the period ending one (1) year after the Effective Time. Thereafter, any former holder of Certificates or Book-Entry Shares prior to the Merger who has not complied with this Section 2.03 prior to such time, may look only to the Surviving Corporation for payment of their claim for Merger Consideration to which such holder may be entitled.

(e) No Liability. None of Parent, the Company, the Exchange Agent or the Surviving Corporation, nor any employee, officer, partner, director, agent or Affiliate of the foregoing, shall be liable to any former holder of shares of Company Common Stock for any payment of the Merger Consideration delivered to a public official if required by any applicable abandoned property, escheat or similar Law. Any portion of the Exchange Fund remaining unclaimed by holders of shares of Company Common Stock as of a date that is immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity will, to the extent not prohibited by applicable Law, become the property of Parent, free and clear of all or any claims or interest of any Person previously entitled thereto.

(f) Waiver. The Surviving Corporation may from time to time, in the case of one or more Persons, waive one or more of the rights provided to it in this Article II to withhold certain payments, deliveries and distributions, and no such waiver shall constitute a waiver of its rights thereafter to withhold any such payment, delivery or distribution in the case of any Person.

Exhibit 2.1

(g) Lost, Stolen or Destroyed Certificates. If any Certificate formerly representing shares of Company Common Stock has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by ▇▇▇▇▇▇, the posting by such Person of a bond, in such reasonable and customary amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall deliver and pay, in exchange for such lost, stolen or destroyed certificate, the Merger Consideration payable in respect thereof pursuant to this Agreement.

(h) Investment of Exchange Fund. The Exchange Agent shall invest any cash in the Exchange Fund if and as directed by ▇▇▇▇▇▇; provided that such investment shall be (1) in obligations of, or guaranteed by the full faith and credit of, the United States, (2) in commercial paper obligations of issuers organized under the Law of a state of the United States, rated P-1 or A-1 or better by ▇▇▇▇▇’▇ Investors Service, Inc. or Standard & Poor’s Ratings Service, respectively, (3) in certificates of deposit, bank repurchase agreements or bankers’ acceptances of commercial banks with capital exceeding ten billion dollars ($10,000,000,000), or (4) in mutual funds investing solely in such assets referred to in the foregoing clauses (1) through (3). Any interest and other income resulting from such investments shall be paid to, and be the property of, Parent. No investment losses resulting from the Exchange Fund shall diminish the rights of any holders of shares of Company Common Stock, Company Restricted Stock Units or Company Performance Stock to receive the Merger Consideration or any other payment as provided herein. To the extent, for any reason, the amount in the Exchange Fund is below what is required to make prompt payment of the aggregate cash payments contemplated by this Article II, Parent shall promptly replace, store or supplement (or cause to be replaced, stored or supplemented) the cash in the Exchange Fund so as to ensure that the Exchange Fund is at all times maintained at a level sufficient for the Exchange Agent to make the payment of the aggregate cash payments contemplated by this Article II.

(i) Withholding. Parent, the Surviving Corporation, Merger Sub, any Affiliates of the Surviving Corporation and the Exchange Agent shall be entitled to (i) deduct and withhold from the Merger Consideration and any other amounts payable pursuant to this Agreement such amounts as are required to be deducted and withheld with respect to the making of such payment under the Code, or under any provision of state, local or non-U.S. Tax Law and (ii) reasonably request any necessary Tax forms, including Internal Revenue Service Form W-9 or the appropriate series of Form W-8, as applicable (together with any applicable underlying forms or documentation) from any Person to whom a payment is to be made pursuant to this Agreement. To the extent amounts are so withheld and paid over to the appropriate Governmental Entity, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding were made.

Section 2.04 Equity Awards. At or prior to the Effective Time, the Company shall take such actions as are necessary (including obtaining any resolutions of the Company Board or, if appropriate, any committee thereof administering the Company Stock Plans) to effect the following:

(a) Company Restricted Stock Units. Each Company Restricted Stock Unit that is outstanding and unvested immediately prior to the Effective Time shall be canceled as of

Exhibit 2.1

the Effective Time and converted into a contingent right to receive, from Parent or the Surviving Corporation (a “Converted Cash Award”), an aggregate amount, without interest, in cash equal in value to (i) the number of shares of Company Common Stock subject to such Company Restricted Stock Unit award immediately prior to the Effective Time after giving effect to the accumulation of dividend equivalents credited in respect of such Company Restricted Stock Units, multiplied by (ii) the Merger Consideration. Each such Converted Cash Award assumed and converted pursuant to this Section 2.04(a) will continue to have and will be subject to, the same terms and conditions as applied to the corresponding Company Restricted Stock Unit immediately prior to the Effective Time. This Section 2.04(a) (rather than Section 2.01(a)) shall govern the treatment of Company Restricted Stock Units at the Effective Time. Each Company Restricted Stock Unit that is outstanding and vested immediately prior to the Effective Time shall be canceled as of the Effective Time and converted into a right to receive, from Parent or the Surviving Corporation, an aggregate amount, without interest, in cash equal in value to (x) the number of shares of Company Common Stock subject to such vested Company Restricted Stock Unit award immediately prior to the Effective Time after giving effect to the accumulation of dividend equivalents credited in respect of such Company Restricted Stock Units, multiplied by (y) the Merger Consideration. Payment with respect to the Company Restricted Stock Units described in the preceding sentence shall be made through payroll of the Surviving Corporation or the applicable Company Subsidiary as soon as reasonably practicable following the Closing Date, subject to deduction for any applicable withholding Taxes required to be made under applicable Law.

(b) Company Performance Stock. Each share of Company Performance Stock that is outstanding and unvested immediately prior to the Effective Time shall be canceled as of the Effective Time and converted into a vested right to receive, without interest, the Merger Consideration with respect to a pro-rata portion of the number of shares of Company Common Stock subject to such Company Performance Stock award, based on attainment of the applicable performance metrics at the greater of (i) the number determined in accordance with the performance criteria as otherwise provided in the applicable award agreement and as if the performance period ended as of the last Business Day immediately preceding the Closing Date and (ii) the target award as provided in the applicable award agreement, in either case, prorated, after giving effect to the accumulation of dividend equivalents credited in respect of such Company Performance Stock, based on the number of whole calendar months within the vesting period that has elapsed as of the Effective Time in relation to the number of calendar months in the entire vesting period (the “Applicable Company Performance Stock”). In each case, payment with respect to any Applicable Company Performance Stock shall be made through payroll of the Surviving Corporation or the applicable Company Subsidiary as soon as reasonably practicable following the Closing Date, subject to deduction for any applicable withholding Taxes required to be made under applicable Law. At the Effective Time, any outstanding portion of a Company Performance Stock award that is not the Applicable Company Performance Stock shall be canceled and converted into a Converted Cash Award with respect to an aggregate amount, without interest, in cash equal in value to (A) the prorated number of shares of Company Performance Stock that is not the Applicable Company Performance Stock after giving effect to the deemed performance determination as described above with respect to the Applicable Company Performance Stock, multiplied by (B) the Merger Consideration, subject to deduction for any applicable withholding Taxes required to be made under applicable Law. Each such Converted Cash Award assumed and converted pursuant to this Section 2.04(b) will continue to have and will be subject to, the same terms and conditions (including time-based vesting conditions, but excluding performance-based vesting conditions) as applied to the corresponding

Exhibit 2.1

The Company shall provide prompt notice to Parent of any demands, communications, attempted withdrawals of such demands and any other instruments served pursuant to Sections 302A.471 and 302A.473 of the MBCA or which otherwise makes any demand for payment of the fair value of any shares of Company Common Stock, that are received by the Company for Dissenters’ Rights with respect to any shares of Company Common Stock, and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands.

(f) For the avoidance of doubt, this Section 5.01 does not relate to the ability of the Company or the Company Subsidiaries to make filings in connection with, or agree to settlement or stipulation of, Regulatory Proceedings.

Section 5.02 Regulatory Proceedings.

(a) Between the date of this Agreement and the Closing, the Company and the Company Subsidiaries may (i) initiate any Regulatory Proceeding or (ii) enter into any settlement or stipulation in respect of any Regulatory Proceeding, in any case, (A) in the ordinary course of business, (B) as set forth on Section 5.02(a) of the Company Disclosure Letter or (C) otherwise with the prior written consent of Parent (such consent not to be unreasonably withheld, delayed or conditioned), other than in each case, with respect to any Material Regulatory Proceeding, which shall require the prior written consent of Parent (such consent not to be unreasonably withheld, delayed or conditioned). Notwithstanding anything in this Agreement to the contrary, the terms of Section 6.03 shall control with respect to any Regulatory Proceeding under Section 6.03, including any Filing made in connection therewith.

(c) In the event that the Company or any Company Subsidiary would be prohibited from taking any action by reason of this Section 5.02 without the prior written consent

Exhibit 2.1

of Parent, such action may nevertheless be taken without such consent if the Company requests ▇▇▇▇▇▇’s prior written consent (provided that such request is made via email and delivered to each of the Notice Individuals) and Parent fails to respond in writing or fails to withhold its consent to such request within 10 Business Days after the date such request is delivered; provided that Parent shall use reasonable best efforts to respond within any such shorter time period as may be requested by the Company and reasonably warranted by the circumstances.

(d) For the avoidance of doubt, this Section 5.02 shall not relate to any Tax matter.

Section 5.03 No Solicitation by the Company; Company Board Recommendation.

(a) The Company shall not, and shall cause its Subsidiaries and its and their respective directors, officers and employees not to, and shall instruct its other Representatives not to, (i) directly or indirectly solicit, initiate or knowingly encourage, induce or facilitate any Company Takeover Proposal or any inquiry, offer or proposal that constitutes, or would reasonably be expected to lead to, a Company Takeover Proposal, in each case, except for this Agreement and the transactions contemplated hereby, or (ii) directly or indirectly participate in any discussions or negotiations with any Person (except between the Company’s Affiliates and its and their respective Representatives, on the one hand, and Parent, Merger Sub and their Affiliates and its and their respective Representatives, on the other hand) regarding, or furnish to any such Person, any nonpublic information relating to, or afford any Person access to, the business, operations, assets, books, records or personnel of, the Company or any Company Subsidiary with respect to, or cooperate in any way with any such Person with respect to, any Company Takeover Proposal or any inquiry, offer or proposal that constitutes, or would reasonably be expected to lead to, a Company Takeover Proposal. The Company shall, and shall cause its Affiliates and its and their respective Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any Person (except between the Company’s Affiliates and its and their respective Representatives, on the one hand, and Parent and Parent’s Affiliates and its and their respective Representatives, on the other hand) conducted heretofore with respect to any Company Takeover Proposal or any inquiry, offer or proposal that constitutes, or would reasonably be expected to lead to, a Company Takeover Proposal, request the prompt return or destruction of all nonpublic information previously furnished and immediately terminate all physical and electronic data room access previously granted to any such Person or its Representatives. Notwithstanding anything to the contrary herein, at any time prior to obtaining the Company Shareholder Approval, in response to the receipt of a bona fide written Company Takeover Proposal made after the date of this Agreement that does not result from a breach (other than an immaterial breach) of this Section 5.03(a) by the Company and that the Company Board determines in good faith (after consultation with outside legal counsel and a nationally recognized financial advisor) constitutes or would reasonably be expected to lead to a Superior Company Proposal and the failure to take such action described in clause (1) or (2) of this Section 5.03(a) would be reasonably likely to be inconsistent with the fiduciary duties of the Company Board under applicable Law, the Company and its Representatives may (1) furnish information with respect to the Company and the Company Subsidiaries to the Person making such Company Takeover Proposal (and its Representatives) (provided that all such information has previously been provided to Parent or is provided to Parent as promptly as practicable after, and in any event within twenty-four (24) hours of, the provision of such information to such

Exhibit 2.1

Person) pursuant to an Acceptable Confidentiality Agreement that does not restrict the Company’s ability to comply with its obligations under this Section 5.03 and (2) participate in discussions regarding the terms of such Company Takeover Proposal, including terms of a Company Acquisition Agreement with respect thereto, and the negotiation of such terms with the Person making such Company Takeover Proposal (and such Person’s Representatives) pursuant to an Acceptable Confidentiality Agreement. Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in this Section 5.03 by any Representative of the Company or any of its Affiliates shall constitute a breach of this Section 5.03 by the Company. Notwithstanding anything to the contrary herein, the Company may grant a waiver, amendment or release under any confidentiality or standstill agreement to the extent necessary to allow a confidential Company Takeover Proposal to be made to the Company or the Company Board so long as the Company Board promptly (and in any event, within twenty-four (24) hours) notifies Parent thereof after granting any such waiver, amendment or release and the Company Board determines, prior to granting any such waiver, amendment or release, in good faith (after consultation with outside legal counsel) that the failure to grant such waiver, amendment or release would be reasonably likely to be inconsistent with the Company’s Board’s fiduciary duties under applicable Law.

(b) Except as set forth in Section 5.03(a), Section 5.03(c), Section 5.03(e) and Section 5.03(f), and except for the public disclosure of a Company Recommendation Change Notice made in compliance with this Agreement, neither the Company Board nor any committee thereof shall (i) withdraw, change, qualify, withhold, modify in any manner adverse to Parent, or propose publicly to withdraw, change, qualify, withhold or modify in any manner adverse to Parent, the Company Board Recommendation, (ii) adopt, approve, declare advisable or recommend, or propose publicly to adopt, approve, declare advisable or recommend, any Company Takeover Proposal, (iii) fail to include in the Proxy Statement the Company Board Recommendation (except as set forth in Section 6.01(a)), (iv) fail to expressly reaffirm publicly the Company Board Recommendation following Parent’s written request to do so if a Company Takeover Proposal is publicly announced or disclosed (provided that Parent may only make such request two (2) times with respect to any particular Company Takeover Proposal or any material publicly announced or disclosed amendment or modification thereto), on or prior to the earlier of (A) the fifth (5th) Business Day after the delivery of such request by Parent and (B) two (2) Business Days prior to the Company Shareholders Meeting (or any adjournment or postponement thereof) or (v) take any formal action or make any recommendation or public statement in connection with a tender offer or exchange offer (except for a recommendation against such offer or a customary “stop, look and listen” communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) (any action in the foregoing clauses (i)–(v) being referred to as a “Company Adverse Recommendation Change”). Except as set forth in Section 5.03(a), Section 5.03(c), Section 5.03(e) and Section 5.03(f), neither the Company Board nor any committee thereof shall authorize, permit, approve or recommend, or propose publicly to authorize, permit, approve or recommend, or allow the Company or any of its Affiliates to execute or enter into, any Contract, letter of intent, memorandum of understanding, agreement in principle, agreement, merger agreement, acquisition or similar agreement or commitment constituting, or that would reasonably be expected to lead to, any Company Takeover Proposal, or requiring, or that would reasonably be expected to cause, the Company to abandon or terminate this Agreement (a “Company Acquisition Agreement”).

Exhibit 2.1

(c) Notwithstanding anything to the contrary herein, at any time prior to obtaining the Company Shareholder Approval, the Company Board may make a Company Adverse Recommendation Change or terminate this Agreement in accordance with Section 8.01(c)(i) (subject to the satisfaction of the conditions therein), in each case, if the Company has received a Superior Company Proposal that does not result directly or indirectly from a breach (other than an immaterial breach) of Section 5.03 by the Company or any Company Subsidiary and, in each case, only if the Company Board determines in good faith (after consultation with outside legal counsel and a nationally recognized financial advisor) that the failure to effect a Company Adverse Recommendation Change or terminate this Agreement in accordance with Section 8.01(c)(i) in response to the receipt of such Superior Company Proposal, as the case may be, would be reasonably likely to be inconsistent with the Company Board’s fiduciary duties under applicable Law; provided, however, that the Company Board may not make such Company Adverse Recommendation Change or terminate this Agreement pursuant to Section 8.01(c)(i) unless (i) the Company Board has provided prior written notice to Parent (a “Company Recommendation Change Notice”) that it is prepared to effect a Company Adverse Recommendation Change or terminate this Agreement in accordance with Section 8.01(c)(i) at least four (4) Business Days prior to taking such action, which notice shall specify the basis for such action and, in the case of a Superior Company Proposal, attaching the most current draft of any Company Acquisition Agreement with respect to such Superior Company Proposal or, if no draft exists, a summary of the material terms and conditions of such Superior Company Proposal (it being understood that such Company Recommendation Change Notice shall not in itself be deemed a Company Adverse Recommendation Change and that if there has been any subsequent material revision or amendment to the terms of a Superior Company Proposal, a new notice to which the provisions of clauses (iii) and (iv) of this Section 5.03(c) shall apply mutatis mutandis except that, in the case of such a new notice, all references to four (4) Business Days in this Section 5.03(c) shall be deemed to be two (2) Business Days), (ii) the Company has provided to Parent, prior to the commencement of such four (4) Business Day period, the information with respect to such Company Takeover Proposal required to be provided pursuant to Section 5.03(a) and Section 5.03(d), (iii) during the four (4) Business Day period after delivery of the Company Recommendation Change Notice, if requested by Parent, the Company and its Representatives negotiate in good faith with Parent and its Representatives regarding any revisions to this Agreement that Parent proposes to make as would permit the Company Board in the exercise of its fiduciary duties not to effect a Company Adverse Recommendation Change or terminate this Agreement pursuant to Section 8.01(c)(i), and (iv) at the end of such four (4) Business Day period and taking into account any changes to the terms of this Agreement committed to in writing by Parent, the Company Board determines in good faith (after consultation with outside legal counsel and a nationally recognized financial advisor) that the failure to make such a Company Adverse Recommendation Change or terminate this Agreement in accordance with Section 8.01(c)(i) would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law, and that, such Company Takeover Proposal still constitutes a Superior Company Proposal.

(d) The Company shall promptly (and in any event no later than twenty-four (24) hours after receipt) advise Parent orally and in writing of any Company Takeover Proposal, the material terms and conditions of any such Company Takeover Proposal and the identity of the Person making such Company Takeover Proposal. The Company shall keep Parent reasonably informed in all material respects on a reasonably current basis (and in any event no

Exhibit 2.1

later than twenty-four (24) hours thereafter) of the material terms and status (including any change to the terms thereof) of any Company Takeover Proposal. Without limiting the foregoing, the Company shall notify Parent in writing promptly (and in any event within twenty-four (24) hours) after it determines to begin providing information or to engage in discussions or negotiations concerning a Company Takeover Proposal.

(e) Notwithstanding anything to the contrary herein, at any time prior to obtaining the Company Shareholder Approval, the Company Board may make a Company Adverse Recommendation Change in accordance with this Section 5.03(e) if a Company Intervening Event has occurred and the Company Board determines in good faith (after consultation with outside legal counsel and a nationally recognized financial advisor) that the failure to effect a Company Adverse Recommendation Change as a result of the occurrence of such Company Intervening Event would be reasonably likely to be inconsistent with the Company Board’s fiduciary duties under applicable Law; provided, however, that the Company Board may not make such Company Adverse Recommendation Change unless (i) the Company Board has provided a Company Recommendation Change Notice that it is prepared to effect a Company Adverse Recommendation Change at least four (4) Business Days prior to taking such action, which notice shall specify the basis for such Company Adverse Recommendation Change, (ii) during the four (4) Business Day period after delivery of the Company Recommendation Change Notice, if requested by Parent, the Company and its Representatives negotiate in good faith with Parent and its Representatives regarding any revisions to this Agreement that Parent proposes to make and (iii) at the end of such four (4) Business Day period and taking into account any changes to the terms of this Agreement committed to in writing by Parent, the Company Board determines in good faith (after consultation with outside legal counsel and a nationally recognized financial advisor) that the failure to make such a Company Adverse Recommendation Change would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law.

(f) Nothing contained in this Section 5.03 shall prohibit the Company from (i) complying with Rule 14d-9 and Rule 14e-2 promulgated under the Exchange Act or (ii) making any disclosure to the shareholders of the Company if, in the good-faith judgment of the Company Board (after consultation with outside legal counsel), failure to so disclose would be reasonably likely to be inconsistent with its obligations under applicable Law.

(a) Each of Parent and Merger Sub shall use its reasonable best efforts to, and shall use its reasonable best efforts to cause each of its respective Affiliates and Representatives to, take all actions and do all things necessary, proper or advisable to obtain the net proceeds of the Financing, or any Substitute Financing, in each case, on the terms and subject only to the conditions expressly set forth in the Financing Commitment Letters (including any “market flex” provisions set forth in any Debt Letter) and subject to any modifications permitted by this Section 5.04 at or prior to the Closing Date, including (i) maintaining in effect the Financing Commitment Letters and complying with all of their respective obligations thereunder to the extent required as a condition to accessing such Financing, (ii) negotiating, entering into and delivering definitive agreements with respect to the Financing (the “Definitive Agreements”) on the terms contained in the Financing Commitment Letters (including any “market flex” provisions set forth in any Debt Letter) (or with other terms reasonably acceptable to Parent and without any Prohibited Modifications) and subject only to the conditions expressly set forth in the Financing Commitment Letters on the date of this Agreement, (iii) satisfying on a timely basis all conditions in the Financing Commitment Letters and the Definitive Agreements that are applicable to Parent or any of its Affiliates or Representatives that are within their control, (iv) if required under the Debt Letters, entering into amendments to the Definitive Agreements with respect to the Debt Financing to give effect to any “market flex” provisions contained in any Debt Letter and (v) subject to the satisfaction of the conditions set forth in Section 7.01 and Section 7.03 (other than those conditions to be satisfied substantially concurrently with the Closing), consummating, and obtaining the net proceeds of, the Financing no later than the Closing.

(b) In the event that all conditions set forth in Article VII have been satisfied or waived or, upon funding shall be satisfied or waived, each of Parent and Merger Sub shall use its reasonable best efforts to, and shall use its reasonable best efforts to cause each of their respective Affiliates and Representatives to, cause each applicable Person that is a party to any of the Financing Commitment Letters to fund the Financing in accordance with its terms on the Closing Date to the extent the proceeds thereof are required to pay the Required Amount and

Exhibit 2.1

consummate the Merger and the other transactions contemplated thereby. Each of Parent and Merger Sub shall not, and shall use its reasonable best efforts to cause its Affiliates and Representatives not to, take or refrain from taking, directly or indirectly, any action that would reasonably be expected to result in a failure of the Financing (other than as expressly provided by the Debt Letters in respect of the “Backstop Revolving Credit Facility” and the “Backstop L/C Facility” (as such terms are defined in the Debt Commitment Letter)) to be available and funded in the Required Amount at or prior to the Closing; provided that Parent shall be permitted to terminate commitments in respect of the “Backstop Term Loan Facility” (as such term is defined in the Debt Commitment Letter).

(c) Upon reasonable request by the Company from time to time, Parent shall keep the Company reasonably informed on a current and timely basis of the status of Parent’s efforts to obtain the Financing and to satisfy the conditions thereof, including advising and updating the Company, in a reasonable level of detail, with respect to status, proposed closing date of the Financing and material terms of the Definitive Agreements and providing copies of substantially final drafts of the primary Definitive Agreements (including, with respect to the Debt Financing, the credit agreement) with sufficient time for the Company to review with its counsel (provided that any fee letter and any engagement letter for the placement of debt securities may be redacted solely as to fee amounts and other economic terms (including any such terms included in the “market flex”) that are customarily redacted in connection with similar financings and that could not adversely affect the conditionality, enforceability, amount, availability or termination of the Financing). Without limiting the generality of the foregoing, Parent shall give the Company prompt written notice (i) of any breach or default (or alleged or purported breach or default), or any event or circumstance that (with or without notice, lapse of time or both) would reasonably be expected to give rise to any breach or default, by any party to any of the Financing Commitment Letters or Definitive Agreements, (ii) of any termination or repudiation (or alleged or purported termination or repudiation) of any of the Financing Commitment Letters or Definitive Agreements, and (iii) if for any reason at any time Parent believes that it may not be able to obtain all or any portion of the Financing on the terms, in the manner or from the sources contemplated by the Financing Commitment Letters or any Definitive Agreement. Parent shall provide any information reasonably requested by the Company relating to any of the circumstances referred to in clauses (i), (ii) or (iii) of the immediately preceding sentence promptly after the Company makes any such request.

(d) Neither Parent nor Merger Sub shall, without the Company’s prior written consent: permit any amendment, supplement, modification, assignment, termination, replacement or waiver to be made to, or consent to any waiver of, any provision of or remedy under any of the Financing Commitment Letters or Definitive Agreements if such amendment, supplement, modification, termination, assignment, replacement or waiver would or would reasonably be expected to (1) reduce the aggregate amount of the Financing (including by increasing the amount of fees to be paid or original issue discount) below the Required Amount (when taken together with other sources of funds immediately available to Parent (including additional equity commitments that will be funded at or prior to Closing)); provided that Parent shall be permitted to terminate commitments in respect of the “Backstop Term Loan Facility” (as such term is defined in the Debt Commitment Letter), (2) impose new or additional conditions to the Financing or otherwise expand, amend or modify any of the existing conditions to the Financing, (3) adversely impact the ability of Parent or Merger Sub to enforce its rights against any other

Exhibit 2.1

party to any of the Financing Commitment Letters or Definitive Agreements or (4) otherwise expand, amend, modify or waive any provision of any of the Financing Commitment Letters or Definitive Agreements in a manner that in any such case would or would reasonably be expected to prevent, delay or make less likely (A) the funding of the Financing in an amount no less than the Required Amount (or satisfaction of the conditions to the Financing) at or prior to the Closing or (B) the timely consummation of the Merger and the other transactions contemplated hereby (the effects described in clauses (1) through (4), the “Prohibited Modifications”); provided that Parent may amend the Debt Letters to add Debt Financing Entities that have not previously executed the Debt Letters as of the date of this Agreement without the prior written consent of the Company. In the event that any new debt or equity commitment letters or fee letters are entered into in accordance with any termination, amendment, replacement, supplement, modification or waiver of any Financing Commitment Letter or Definitive Agreement permitted pursuant to this Section 5.04(d), references to the “Financing,” “Debt Financing Parties,” “Definitive Agreements” and “Financing Commitment Letters” (and other like terms in this Agreement) shall be deemed to refer to the Financing as so terminated, amended, supplemented, modified, waived or replaced for all purposes of this Agreement and each such term shall be construed accordingly. Parent shall promptly deliver to the Company copies of any termination, amendment, supplement, modification, waiver or replacement of any Financing Commitment Letter or Definitive Agreement and each other agreement entered into in connection therewith (provided that any fee letter may be redacted solely as to fee amounts and other economic terms (including any such terms included in the “market flex”) that are customarily redacted in connection with similar financings and that could not adversely affect the conditionality, enforceability, amount, availability or termination of the Financing).

(e) If any portion of the Financing becomes, or is expected to become, unavailable for any reason (other than on account of Parent’s termination of commitments in respect of the “Backstop Term Loan Facility” (as such term is defined in the Debt Commitment Letter)), Parent shall, and shall cause its Affiliates and relevant Representatives, as promptly as practicable following the occurrence of such event, to (i) notify the Company in writing thereof and the reason therefor, (ii) use its reasonable best efforts to obtain substitute financing in an amount sufficient, when taken together with any available portion of the Financing, to enable Parent to consummate the Merger and the other transactions contemplated hereby in accordance with its terms (including to pay the Required Amount) and which does not include any Prohibited Modification or condition to the consummation of such substitute financing that is more onerous in any significant respect than the conditions set forth in the Financing Commitment Letters as of the date of this Agreement (any such substitute financing, the “Substitute Financing”) and (iii) use its reasonable best efforts to obtain a new financing commitment letter that provides for such Substitute Financing and, promptly after execution thereof, deliver to the Company true, complete and correct copies of the new commitment letter and all related fee letters (provided that any such fee letter may be redacted solely as to fee amounts and other economic terms (including any such terms included in the “market flex”) that are customarily redacted in connection with similar financings and that could not adversely affect the conditionality, enforceability, amount, availability or termination of the Financing) and related definitive financing documents with respect to such Substitute Financing; provided, however, that Parent shall not be required to obtain financing that includes terms and conditions materially less favorable (taking into account any “market flex” provisions) to Parent, relative to those in the portion of the Financing being replaced. Upon obtaining any

Exhibit 2.1

commitment for any such Substitute Financing, references to the “Financing,” “Debt Financing Parties,” “Definitive Agreements”, “Financing Commitment Letters” “Debt Commitment Letter” and “Debt Letters” (and other like terms in this Agreement) shall be deemed to refer to such Substitute Financing and the commitments thereunder and the agreements with respect thereto for all purposes of this Agreement and each such term shall be construed accordingly.

(f) Parent shall pay, or cause to be paid, as the same shall become due and payable, all fees and other amounts that become due and payable under the Financing Commitment Letters.

(g) Notwithstanding anything contained in this Agreement to the contrary, ▇▇▇▇▇▇ and ▇▇▇▇▇▇ Sub expressly acknowledge and agree that neither ▇▇▇▇▇▇’s nor ▇▇▇▇▇▇ Sub’s obligations hereunder are conditioned in any manner upon Parent or Merger Sub obtaining the Financing, any Substitute Financing or any other financing.

The Company shall maintain its existing corporate and facility ratings (but not any specific rating). From the date hereof until the Closing (or the earlier termination of this Agreement pursuant to Section 8.01), subject to the limitations set forth in this Section 5.05, and unless otherwise agreed by Parent, the Company will use its reasonable best efforts, will cause each of its Subsidiaries to use reasonable best efforts, and will use its reasonable best efforts to cause its and its Subsidiaries’ Representatives to use reasonable best efforts, to provide customary cooperation to Parent, as reasonably requested by Parent as may be necessary or desirable for Parent’s arrangement of the Debt Financing. Such cooperation will include using reasonable best efforts, upon Parent’s reasonable request, to:

(i) cooperate with the marketing efforts of Parent solely in connection with the Debt Financing, including making appropriate senior officers of the Company available to participate in a reasonable number of lender or investor meetings, due diligence sessions, meetings with ratings agencies and road shows, in each case, at reasonable times and locations mutually agreed and upon reasonable prior notice (it being understood that any such meetings may take place via videoconference or web conference at the Company’s option);

(ii) provide reasonable and customary assistance to Parent in Parent’s preparation of customary confidential information memoranda, private placement memoranda, offering memoranda, prospectuses, lender and investor presentations and similar documents customarily required in connection with financings of a type similar to the Debt Financing and as may be reasonably requested by Parent, in each case, with respect to historical information relating to the Company and its Subsidiaries in connection with such marketing efforts for the Debt Financing;

(iii) to the extent contemplated by or required under the Debt Commitment Letter, provide customary authorization letters to the Debt Financing Entities to accompany customary marketing materials in respect of the Debt Financing,

The Company hereby consents to the use of its and its Subsidiaries’ logos in connection with the Debt Financing; provided, however, that such logos are used solely in a manner that is not intended, or reasonably likely, to harm or disparage the Company or any of its Subsidiaries or any of their respective Affiliates or Representatives or the reputation or goodwill of any of the foregoing.

(c) Parent shall (i) promptly upon request by the Company, reimburse the Company for all of its reasonable and documented out-of-pocket fees and expenses (including reasonable and documented out-of-pocket fees and expenses of counsel and accountants) incurred by the Company or any of its Affiliates or any of their respective Subsidiaries or Representatives in connection with the Debt Financing, including any cooperation related thereto and (ii) indemnify and hold harmless the Company and its Affiliates and any of their respective Subsidiaries or Representatives against any claim, loss, damage, injury, liability, judgment, award, penalty, fine, cost (including cost of investigation), expense (including fees and expenses of counsel and accountants) or settlement payment incurred as a result of, or in connection with, such cooperation or the Debt Financing and any information used or misused in connection therewith other than those claims, losses, damages, injuries, liabilities, judgments, awards, penalties, fines, costs, expenses and settlement payment arising out of or resulting from the fraud, gross negligence or willful misconduct of the Company, its Subsidiaries or their respective Affiliates and Representatives as finally determined by a court of competent jurisdiction.

(f) Notwithstanding anything in this Agreement to the contrary, in no event shall the receipt by, or availability to, Parent or any of its Affiliates of any funds or financing or any other financing transaction (including the Debt Financing) be a condition to Parent’s or Merger Subs’ obligations to effect the Closing.

(g) The Company and its Subsidiaries shall deliver payoff or similar notices with respect to any Indebtedness requested by Parent at least ten (10) Business Days prior to the anticipated Closing Date to the applicable agents, trustees or financing sources thereunder within the time frames required by the terms of such Indebtedness.

In lieu of such insurance, prior to the Closing Date the Company may, at its option, purchase a “tail” directors’ and officers’ liability insurance policy and fiduciary liability insurance policy for the Company and its current and former directors, officers and employees who are currently covered by the directors’ and officers’ and fiduciary liability insurance coverage currently maintained by the Company, such tail to provide coverage in an amount not less than the existing coverage and to have other terms not materially less favorable to the insured persons than the directors’ and officers’ liability insurance and fiduciary liability insurance coverage currently maintained by the Company with respect to claims arising from facts or events that occurred on or before the Effective Time for a period of not less than six (6) years; provided that in no event shall the cost of any such tail policy in respect of any one policy year exceed the Maximum Amount.

In the event that any such Transition Committee member is unable to attend a meeting of the Transition Committee or is otherwise temporarily unavailable to discharge his or her

Exhibit 2.1

duties in connection with the Transition Committee, the Company, GIP or CPPIB, as applicable, shall have the right to designate one “alternate” individual to the Transition Committee. Such “alternate” individual shall be entitled to attend meetings of the Transition Committee in place of the originally designated committee member for so long as such Transition Committee member is unable to attend meetings of the Transition Committee or is otherwise unavailable to discharge his or her duties in connection therewith. The Transition Committee will meet at least monthly until the earlier of the termination of this Agreement and the Effective Time (and such meeting may be by telephonic or video conference in lieu of an in-person meeting). The Company will use reasonable best efforts to prepare and deliver three (3) Business Days prior to such meeting a reasonable agenda for each meeting of the Transition Committee and shall provide Parent with a reasonable opportunity to review such agenda and consider in good faith any reasonable addition or modification proposed by Parent to such agenda. Notwithstanding anything herein to the contrary, the Company shall be permitted to invite additional Company Personnel to attend any meeting of the Transition Committee as reasonably necessary or appropriate. Notwithstanding the foregoing, and for the avoidance of doubt, the obligations of the Parties under this Section 6.16 are in addition to any other obligations of the Parties in this Agreement.

Section 6.17 2025 Notes Refinancing. The Company shall use best efforts to refinance, redeem, repurchase or otherwise repay all outstanding 2025 Notes on or prior to 90 days after the date hereof using, together with de minimis cash on hand, the proceeds of, or in exchange for, one or more new series of non-convertible senior unsecured indebtedness, which indebtedness shall (i) be on the market terms reasonably available to the Company at the time (provided, that such terms shall not restrict the ability of the Company or any Subsidiary to pay dividends or distributions or repurchase or redeem equity interests, unless Parent consents to the inclusion of any such restriction), (ii) expressly permit all transactions contemplated by this Agreement (including the Financing), and (iii) not result in any material adverse tax consequences for the Company (including any such material adverse tax consequences for the Company that are required to be reflected on a Tax Return of Parent or any consolidated, unitary or combined tax group of which the Company or any successor thereto is a member). The Company shall consult with Parent on such refinancing, including with respect to the terms of such refinancing indebtedness. If no such refinancing is completed within such 90-day period, without prejudice to the Parent’s other rights under this Agreement, the Company shall (i) authorize and empower Parent to direct a refinancing by the Company of all outstanding 2025 Notes, and the Company shall reasonably cooperate in all respects with requests of Parent to consummate or facilitate consummation of such refinancing prior to Closing (including executing any documents in connection with such refinancing) and (ii) undertake at such time as the Parent shall select and actively support a consent solicitation with respect to the 2025 Notes to shorten the notice period to optionally redeem the 2025 Notes to five business days (or such other period as Parent shall agree), allow any optional redemption notices in connection with the Merger to be conditional and any other amendments reasonably requested by Parent.

Section 6.18 Interim Financing.

(b) (i) At any time during the period from July 1, 2025 to September 30, 2025 (the “First Call Period”), the Company may provide Parent with written notice (provided that such request is made via email and delivered to each of the Notice Individuals) of its intent to raise equity capital in an amount of no less than $50 million and up to $150 million (the “First Tranche Investment”) and Parent shall have ten (10) Business Days to notify the Company of its election to participate in the First Tranche Investment and (ii) at any time during the period from October 1, 2025 to December 31, 2025 (the “Second Call Period”), the Company may provide Parent with written notice of its intent to raise equity capital in an amount of no less than $50 million and up to $300 million (less any amounts called by the Company in connection with the First Tranche Investment) (the “Second Tranche Investment” and together with the First Tranche Investment, the “Preferred Equity Investments” and each, a “Preferred Equity Investment”) and Parent shall have ten (10) Business Days to notify the Company of its election to participate in the Second Tranche Investment. If Parent elects to participate in a Preferred Equity Investment, the Parties shall execute the applicable Interim Investment Documents within five (5) Business Days of Parent’s election in connection with such Preferred Equity Investment and use reasonable best efforts to consummate the Preferred Equity Investment as soon as reasonably practicable, subject to any required regulatory approvals (including (x) any approvals under the HSR Act and (y) Filings with, or Consents of the FERC, the MPUC, the PSCW).

(c) If Parent declines to participate in a Preferred Equity Investment or fails to provide notice within the required ten (10) Business Day period with respect to the applicable Preferred Equity Investment, notwithstanding anything in this Agreement to the contrary, the Company shall thereafter be permitted to issue Company Common Stock for an amount equal to any unfunded amounts under any such Preferred Equity Investment in the public markets.

(d) To the extent permitted by Law, in the event that Parent makes a Preferred Equity Investment, the Interim Investment Documents shall include a waiver of such provisions of the Company Articles as may be inconsistent with the terms contemplated in Exhibit D and the Company and Parent shall cooperate and use reasonable best efforts to ensure that such provisions shall not apply to the Preferred Stock issued in any Preferred Equity Investment. Upon Parent’s or the Company’s request, the Company shall seek shareholder approval of an amendment to the Company Articles at the Company Shareholders Meeting to eliminate such provisions of the Company Articles as may be inconsistent with the terms contemplated in Exhibit D, and the Company and Parent shall cooperate in good faith with respect thereto.

Parent shall pay the Parent General Termination Fee to the Company (to an account designated in writing by the Company)

Exhibit 2.1

prior to or concurrently with such termination of this Agreement by Parent or no later than three (3) Business Days after the date of the applicable termination by the Company.

Without limitation of the foregoing and for the avoidance of doubt, in the event (x) the aggregate Liquidation Preference of all then-outstanding Preferred Stock held by Parent or any of its Affiliates equals or exceeds the applicable Parent Termination Fee otherwise due hereunder and (y) Parent elects to offset the full amount of the Parent Termination Fee by all or a portion of such aggregate Liquidation Preference pursuant to the preceding sentence, then neither Parent nor any of its Affiliates shall thereafter have any liability with respect to any such Parent Termination Fee.

(i) If the Company terminates this Agreement in accordance with Section 8.01(c)(i) (Superior Company Proposal) or Parent terminates this Agreement pursuant to Section 8.01(d)(i) (Company Adverse Recommendation Change), the Company shall pay to Parent the Company Termination Fee. The Company shall pay the Company Termination Fee to Parent (to an account designated in writing by Parent) prior to or concurrently with such termination of this Agreement by the Company in accordance with Section 8.01(c)(i) (provided, in furtherance of Section 8.01(c)(i), the receipt of the Company Termination Fee by Parent shall be required to validly terminate this Agreement) or no later than three (3) Business Days after the date of such termination of this Agreement by Parent pursuant to Section 8.01(d)(i).

(ii) If (1) either (A) Parent or the Company terminates this Agreement pursuant to Section 8.01(b)(i) (End Date) (but only if the Parent Termination Fee is not also payable under Section 8.02(b)(i) or Section 8.02(b)(ii)) or Section 8.01(b)(iii) (No Company Shareholder Approval) or (B) Parent terminates this Agreement pursuant to Section 8.01(d)(ii) (Company Terminable Breach), (2) a Company Takeover Proposal shall have been publicly disclosed or made to the Company or Company Board after the date hereof, and is not withdrawn, and in the case of a publicly disclosed Company Takeover Proposal, publicly withdrawn, (A) in the case of a termination pursuant to Section 8.01(b)(i) (End Date) or Section 8.01(d)(ii) (Company Terminable Breach), prior to the date of such termination, or (B) in the case of a termination pursuant to Section 8.01(b)(iii) (No Company Shareholder Approval), prior to the date of the Company Shareholders Meeting, and (3) within twelve (12) months after the termination of this Agreement, the Company shall have entered into any Company Acquisition Agreement, or consummated such Company Takeover Proposal, then the Company shall pay the Company Termination Fee to Parent (to an account designated in writing by

Exhibit 2.1

Parent) within three (3) Business Days after the earlier of the date the Company enters into such Company Acquisition Agreement or consummates such transaction. For purposes of clause (3) of this Section 8.02(c)(ii), the term “Company Takeover Proposal” shall have the meaning assigned to such term in Section 5.03(g)(i), except that the applicable percentage in the definition of “Company Takeover Proposal” shall be “more than fifty percent (50%)” rather than “twenty percent (20%) or more.”

(d) The Parties acknowledge that the agreements contained in Section 8.02(b) and Section 8.02(c) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the parties would not enter into this Agreement. If Parent fails to promptly pay an amount due (and not otherwise set off against the Liquidation Preference in accordance with Section 8.02(b)(iii)) pursuant to Section 8.02(b)(i) or Section 8.02(b)(ii) or the Company fails to promptly pay an amount due pursuant to Section 8.02(c)(i) or Section 8.02(c)(ii) and, in order to obtain such payment, Parent, on the one hand, or the Company, on the other hand, commences a Claim that results in a Judgment against the Company for the amount set forth in Section 8.02(c)(i) or Section 8.02(c)(ii), or any portion thereof, or a Judgment against Parent for the amount set forth in Section 8.02(b)(i) or Section 8.02(b)(ii), or any portion thereof, the Company shall pay to Parent, on the one hand, or Parent shall pay to the Company, on the other hand, its costs and expenses (including reasonable attorneys’ fees and the fees and expenses of any expert or consultant engaged by the Company or Parent, as applicable) in connection with such Claim, together with interest on the amount of such payment from the date such payment was required to be made until the date of payment at the U.S. prime rate as quoted by The Wall Street Journal in effect on the date such payment was required to be made. Notwithstanding anything to the contrary, the Company acknowledges and agrees that in no event shall Parent’s liability under this Agreement, or otherwise in connection with the transactions contemplated hereby, exceed, in all cases, the Liability Limitation. Any amount payable pursuant to Section 8.02(b) or Section 8.02(c) shall be paid by the applicable Party by wire transfer of same-day funds prior to or on the date such payment is required to be made under such section.

(e) Related Parties.

(i) The Company acknowledges and agrees that the Parent Termination Fee, as applicable, is not intended to be a penalty, but rather is liquidated damages in a reasonable amount that will compensate the Company in the circumstances in which such applicable Parent Termination Fee is due and payable, for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Merger and the other transactions contemplated by this Agreement, which amount would otherwise be impossible to calculate with precision. As such, without limiting the rights of the Company under Section 9.10 prior to the termination of this Agreement in accordance with Section 8.01, if this Agreement is terminated under circumstances in which Parent is obligated to pay any Parent Termination Fee under Section 8.02(b)(i) or Section 8.02(b)(ii), upon payment of the applicable Parent Termination Fee and, if applicable, the costs and expenses of the Company pursuant to Section 8.02(d) (but subject, in all cases, to the Liability Limitation) in accordance herewith, Parent, Merger Sub, the guarantors under the Guaranty or any of their respective Affiliates or any of its or their respective former, current or future general or limited partners, direct and indirect

Exhibit 2.1

equityholders, managers, members, directors, officers or Representatives and the Debt Financing Parties (collectively, the “Parent Related Parties”) shall have no further liability or obligation with respect to this Agreement or the transactions contemplated hereby to the Company (including, for the avoidance of doubt, with respect to any additional Parent Termination Fee), the Company Subsidiaries and any of their respective former, current or future officers, directors, partners, stockholders, managers, members or Affiliates (collectively, “Company Related Parties”), and payment of the applicable Parent Termination Fee and, if applicable, the costs and expenses of the Company pursuant to Section 8.02(d) (but subject, in all cases, to the Liability Limitation), by Parent shall be the Company Related Parties’ sole and exclusive remedy against the Parent Related Parties for any and all Claims, losses, liabilities, damages, judgments, inquiries, obligations, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements, suffered or incurred by the Company Related Parties based on, arising out of or related to this Agreement, the Debt Letters, the Equity Commitment Agreement, the transactions contemplated hereby (and the termination or abandonment thereof), the negotiation, performance or subject matter hereof, or any matter forming the basis for such termination (including any Willful Breach), and the Company Related Parties shall not have, and each expressly waives and relinquishes, any other right, remedy or recourse (whether in contract or in tort or otherwise, or whether at law, including at common law or by statute, or in equity). Notwithstanding anything to the contrary in this Agreement, the Parties acknowledge and agree that the Parent, if required to pay a Parent Termination Fee, shall only be required to pay the Parent Regulatory Termination Fee or the Parent General Termination Fee (and never both), and in no event shall Parent be required to pay such Parent Termination Fee on more than one occasion, whether or not such Parent Termination Fee may be payable pursuant to more than one provision of this Agreement at the same time or at different times and upon the occurrence of different events.

(ii) Parent acknowledges and agrees that the Company Termination Fee is not intended to be a penalty, but rather is liquidated damages in a reasonable amount that will compensate Parent in the circumstances in which the Company Termination Fee is due and payable, for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Merger and the other transactions contemplated by this Agreement, which amount would otherwise be impossible to calculate with precision. As such, without limiting the rights of Parent under Section 9.10 prior to the termination of this Agreement in accordance with Section 8.01, if this Agreement is terminated under circumstances in which the Company is obligated to pay the Company Termination Fee under Section 8.02(c)(i) or Section 8.02(c)(ii), upon payment of the Company Termination Fee and, if applicable, the costs and expenses of Parent pursuant to Section 8.02(d) in accordance herewith, the Company Related Parties shall have no further liability or obligation with respect to this Agreement or the transactions contemplated hereby to the Parent Related Parties, and payment of the Company Termination Fee and, if applicable, the costs and expenses of Parent pursuant to Section 8.02(d) by the Company shall be Parent Related Parties’ sole and exclusive remedy against the Company Related Parties for any and all Claims, losses, liabilities, damages, judgments, inquiries, obligations, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements, suffered or incurred by the

Exhibit 2.1

Parent Related Parties based on, arising out of, or related to this Agreement, the transactions contemplated hereby (and the termination or abandonment thereof), the negotiation, performance or subject matter hereof, or any matter forming the basis for such termination, and the Parent Related Parties shall not have, and each expressly waives and relinquishes, any other right, remedy or recourse (whether in contract or in tort or otherwise, or whether at law, including at common law or by statute, or in equity). Notwithstanding anything to the contrary in this Agreement, the Parties acknowledge and agree that in no event shall the Company be required to pay the Company Termination Fee on more than one occasion, whether or not the Company Termination Fee may be payable pursuant to more than one provision of this Agreement at the same time or at different times and upon the occurrence of different events.

(f) Notwithstanding anything to the contrary in this Agreement, the maximum aggregate liability of Parent and Merger Sub together for any losses, damages, costs or expenses of the Company or its Affiliates related to the failure of the transactions contemplated by this Agreement, or a breach of this Agreement by Parent or Merger Sub or otherwise (including a Willful Breach) shall be as set forth in Section 8.02(f) of the Parent Disclosure Letter (the “Liability Limitation”), and in no event shall the Company, its Subsidiaries or its Affiliates seek any amount in excess of the Liability Limitation (including consequential, indirect or punitive damages) in connection with this Agreement or the transactions contemplated by this Agreement or in respect of any other documents, whether in contract or in tort or otherwise, or whether at law, including at common law or by statute, or in equity; provided that, notwithstanding anything to the contrary, the Company and the Company Related Parties shall be deemed to irrevocably waive their right to any amounts due and owing under this Section 8.02 or otherwise in excess of the Liability Limitation, and none of Parent, any Parent Related Party or the guarantor under the Guaranty shall have any payment obligations in respect of any Parent Termination Fee in excess of the Liability Limitation. In furtherance of the foregoing, in no event shall Parent, any of its Affiliates or Representatives or the Debt Financing Parties be required to pay any amount of monetary losses under this Agreement if the Company is entitled to or has received any Parent Termination Fee.

(g) For purposes of this Agreement, “Willful Breach” means a breach that is a consequence of a deliberate act or deliberate failure to act undertaken by the breaching Party with the Knowledge that the taking of, or failure to take, such act would, or would reasonably be expected to, cause or constitute a material breach of any covenants or agreements contained in this Agreement; provided that, without limiting the meaning of Willful Breach, the Parties acknowledge and agree that any failure by any Party to consummate the Merger and the other transactions contemplated hereby in accordance with Section 1.03 after the applicable conditions to the Closing set forth in Article VII have been satisfied or waived (except for those conditions that by their nature are to be satisfied at the Closing, which conditions would be capable of being satisfied at the time of such failure to consummate the Closing) shall constitute a Willful Breach of this Agreement, except for such failure by Parent to close due solely to the failure of the Debt Financing to be funded on the date the Closing should have occurred.

Section 8.03 Amendment. This Agreement may be amended by the Parties at any time before or after receipt of the Company Shareholder Approval; provided, however, that (a) after receipt of the Company Shareholder Approval, there shall be made no amendment that by Law requires further approval by the shareholders of the Company without the further approval of

Exhibit 2.1

such shareholders, (b) no amendment shall be made to this Agreement after the Effective Time, and (c) except as provided above, no amendment of this Agreement shall require the approval of the shareholders of Parent or the shareholders of the Company. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties.

Section 8.04 Extension; Waiver. At any time prior to the Effective Time, the Parties may (a) extend the time for the performance of any of the obligations or other acts of the other Parties, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant to this Agreement, (c) subject to Section 8.03(a), waive compliance with any covenants and agreements contained herein or (d) waive the satisfaction of any of the conditions contained herein. Any agreement on the part of a Party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. The failure of any Party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

Section 8.05 Procedures for Termination, Amendment, Extension or Waiver. Termination of this Agreement prior to the Effective Time shall not require the approval of the shareholders of any Party. The Party desiring to terminate this Agreement in accordance with Section 8.01 shall give written notice of such termination to the other Parties in accordance with Section 9.02, specifying the provision of this Agreement pursuant to which such termination is effected.

Except for any covenant or agreement that by its terms expressly contemplates performance after the Closing, none of the covenants or agreements of the Parties contained herein shall survive, and all rights, Claims and causes of action (whether in contract or in tort or otherwise, or whether at law, including at common law or by statute, or in equity) with respect to such covenants and agreements shall terminate at, the Closing.

Section 9.03 Definitions. For purposes of this Agreement, each capitalized term has the meaning given to it herein or otherwise given to it or specified in Exhibit A.

Section 9.04 Interpretation.

(a) Time Periods. When calculating the period of time before which, within which or following which any act is to be done or step taken pursuant to this Agreement, (i) the date that is the reference date in calculating such period shall be included, (ii) other than with respect to any obligations set forth in Section 5.03, if the last day of such period is not a Business Day, the period in question shall end on the next succeeding Business Day and (iii) unless otherwise expressly stated, the words “to” and “until” each mean “to but excluding.”

(b) Dollars. Unless otherwise specifically indicated, any reference herein to “$” means U.S. dollars.

(c) Gender and Number. Any reference herein to gender shall include all genders, and words imparting the singular number only shall include the plural and vice versa.

(d) Articles, Exhibits, Sections and Headings. When a reference is made in this Agreement to an Article, Exhibit or Section, such reference shall be to an Article, Exhibit or a Section of this Agreement unless otherwise indicated. The table of contents and headings

Exhibit 2.1

contained in this Agreement or in any Exhibit are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

(e) Include. Whenever the words “include,” “includes” or “including” are used herein, they shall be deemed to be followed by the words “without limitation.”

(f) Hereof. The words “hereof,” “hereto,” “hereby,” “herein” and “hereunder” and words of similar import when used herein shall refer to this Agreement as a whole and not to any particular Article, section or other provision of this Agreement.

(g) Extent. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.”

(h) Laws. Any Law defined or referred to herein means such Law as from time to time amended, modified or supplemented, unless otherwise specifically indicated.

(i) Persons. References to a person are also to its permitted successors and assigns.

(j) Or. Unless otherwise specifically provided herein, the term “or” shall not be deemed to be exclusive.

(k) Exhibits and Disclosure Letters. The Exhibits to this Agreement and the Disclosure Letters are hereby incorporated and made a part hereof and are an integral part of this Agreement. Each of the Company and Parent may, at its option, include in any section of Article III of the Company Disclosure Letter or in any section of Article IV of the Parent Disclosure Letter, respectively, items that are not material in order to avoid any misunderstanding, and such inclusion, or any references to dollar amounts herein or in the Disclosure Letters, shall not be deemed to be an acknowledgement or representation that such items are material, or to establish any standard of materiality or to define further the meaning of such terms for purposes of this Agreement or otherwise. Any matter set forth in any section of the Disclosure Letters shall be deemed to be referred to and incorporated in any section to which it is specifically referenced or cross-referenced. Any matter set forth in any section of Article III of the Company Disclosure Letter shall be deemed to be referred to and incorporated in any other section of Article III of the Company Disclosure Letter to which such matter’s application or relevance is reasonably apparent on the face of such matter. Any matter set forth in any section of Article IV of the Parent Disclosure Letter shall be deemed to be referred to and incorporated in any other section of Article IV of the Parent Disclosure Letter to which such matter’s application or relevance is reasonably apparent on the face of such matter. Any capitalized term used in any Exhibit or any Disclosure Letter but not otherwise defined therein shall have the meaning given to such term herein.

(l) Contracts. Except as otherwise specifically provided herein, all references in this Agreement to any Contract (including this Agreement) shall mean such Contract as amended, supplemented, qualified, modified, varied, restated or replaced from time to time in accordance with the terms thereof as of the date hereof, and includes all addenda, exhibits and schedules to it.

Exhibit 2.1

(m) Made Available. The words “made available to Parent,” “delivered to Parent,” “furnished,” “provided” and words of similar import refer to documents (i) posted to the “Project Polaris” data room hosted by Intralinks by or on behalf of the Company at least twenty-four (24) hours prior to the execution of this Agreement or (ii) delivered in person or electronically to Parent or a Representative thereof at least twenty-four (24) hours prior to the execution of this Agreement.

Section 9.05 Severability. If any term or other provision of this Agreement is finally determined by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced by any applicable rule or Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party or such Party waives its rights under this Section 9.05 with respect thereto. Upon any determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that transactions contemplated by this Agreement are fulfilled to the extent possible.

Section 9.06 Counterparts. This Agreement may be executed in one or more counterparts (including by means of email in .pdf format), all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the Parties and delivered to the other Parties.

Section 9.07 Entire Agreement; No Third-Party Beneficiaries. This Agreement, taken together with the Company Disclosure Letter, the Parent Disclosure Letter and the exhibits hereto and other instruments referred to herein, the Financing Commitment Letters, the Guaranty and the Confidentiality Agreement, constitute the entire agreement, and supersedes all prior agreements and understandings, both written and oral, between or among the Parties with respect to the transactions contemplated by this Agreement, including the Merger. Except as provided in this sentence, Section 6.09 and Section 9.14, each Party agrees that (a) its respective representations, warranties, covenants and agreements set forth herein are solely for the benefit of the other Parties, in accordance with and subject to the terms of this Agreement and (b) this Agreement is not intended to, and does not, confer upon any Person other than the Parties any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein; provided, however, that (i) after the Effective Time (x) the rights of the holders of Company Common Stock, Company Restricted Stock Units or Company Performance Stock to receive the Merger Consideration and payments pursuant to Article II shall be for the benefit of, and shall be enforceable by, each such holder, (y) the provisions in Section 6.09 shall inure to the benefit of the Persons benefiting therefrom who are intended to be third party beneficiaries thereof and (z) the limitations on liability set forth in Section 8.02(e) and Section 8.02(f) shall inure to the benefit of Parent and the Company, and their respective Affiliates and Representatives, as applicable, and the Debt Financing Parties.

Section 9.08 Governing Law. This Agreement, and all Claims or causes of action of the Parties (whether in contract or in tort or otherwise, or whether at law, including at common law or by statute, or in equity) that may be based on, arise out of or relate to this Agreement or the negotiation, execution, performance or subject matter hereof, including matters of validity,

Exhibit 2.1

construction, effect, performance and remedies, shall be governed by and construed in accordance with the Laws of the State of Delaware, without regard to principles of conflict of laws, except that (a) any provisions of this Agreement which implicate the fiduciary duties of directors or officers of a corporation shall be governed by and in accordance with the Laws of Minnesota and (b) to the extent the authorization, effectiveness or effect of the Merger or the transactions are required by statute or public policy to be governed by the Laws of Minnesota, then the internal Laws of Minnesota shall govern and apply, but only as to such matters and to the limited extent necessary to comply with and cause the Merger to be effective under the Laws of Minnesota.

Section 9.09 Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of law or otherwise, by any of the Parties without the prior written consent of the other Parties. Any purported assignment without such consent shall be void; provided that Parent may make a collateral assignment of its rights (but may not assign any obligations) under this Agreement to any Debt Financing Party without the prior written consent of the Company. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Parties and their respective successors and assigns.

Section 9.10 Specific Enforcement.

(a) The Parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and that monetary damages, even if available, would not be an adequate remedy therefor. Subject to the express terms of this Agreement (including Section 9.10(b)), it is accordingly agreed that the Parties shall be entitled to specific performance of the terms hereof, including an injunction or injunctions to prevent breaches of this Agreement (including, at any time prior to the valid termination of this Agreement pursuant to Article VIII, the right of a Party to cause each other Party to consummate the Merger and the other transactions contemplated by this Agreement only when and if permitted under Section 9.10(b)) and any Guaranty, in any court referred to in Section 9.11 or Section 9.14, as applicable, without proof of actual damages (and each Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. The Parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for any such breach.

(b) Notwithstanding anything to the contrary in Section 9.10(a) or elsewhere in this Agreement, it is explicitly agreed that the Company shall be entitled to seek specific performance of Parent’s obligation to cause the Equity Financing to be funded in accordance with terms of the Equity Commitment Agreement and to cause the consummation of the Merger, as applicable, to occur only if (i) this Agreement has not been terminated, (ii) Parent or Merger Sub fail to consummate the Closing by the date the Closing is required to have occurred pursuant to Section 1.03, (iii) the Debt Financing or Substitute Financing with respect to the Debt Financing is funded or the Debt Financing Parties have confirmed in writing that the Debt Financing or Substitute Financing with respect to the Debt Financing will be funded at the Closing if the Equity Financing is funded at the Closing (for purposes of this clause (iii), if any

Exhibit 2.1

amounts committed with respect to the Debt Financing have been funded into escrow, such amounts will be considered funded when the amounts under the Equity Commitment Agreements are funded (to the extent all other conditions to be satisfied under the Debt Commitment Letter for release from escrow have been satisfied)), and (iv) the Company has irrevocably confirmed in a written notice to Parent and Merger Sub that (x) all conditions set forth in Article VII have been satisfied or waived (except for those conditions that by their nature are to be satisfied at the Closing and which conditions are capable of being satisfied at the Closing) and (y) the Company stands ready, willing and able to consummate the Closing and if specific performance is granted and the Equity Financing and Debt Financing are funded, then it will take such actions that are required of it by the terms of this Agreement to cause the Closing to occur.

(c) For the avoidance of doubt, in no event shall the exercise of the Company’s, any Company Subsidiary’s or Parent’s right to seek specific performance pursuant to this Section 9.10 reduce, restrict or otherwise limit the Company’s, such Company Subsidiary’s or Parent’s right, as applicable, to terminate this Agreement pursuant to Article VIII or pursue all applicable remedies at Law, including seeking payment of the Parent Termination Fee in connection with a termination. Notwithstanding the foregoing or elsewhere in this Agreement, while prior to the valid termination of this Agreement, the Company may pursue both a grant of specific performance to cause each other Party to consummate the Merger and the other transactions contemplated by this Agreement only when and if permitted under Section 9.10(b) and payment of the applicable Parent Termination Fee, if, as and when required under Section 8.02(b), in no event shall the Company, directly or indirectly, be permitted or entitled to receive both (i) a grant of specific performance that results in the Closing, on the one hand, and (ii) any monetary damages whatsoever, including payment of any Parent Termination Fee, on the other hand.

Section 9.11 Jurisdiction; Venue. All Claims or causes of action (whether in contract or in tort or otherwise, or whether at law, including at common law or by statute, or in equity) that may be based on, arise out of or relate to this Agreement or the negotiation, execution, performance or subject matter hereof, including matters of validity, construction, effect, performance and remedies shall be raised to and exclusively determined by the Court of Chancery of the State of Delaware or, to the extent such court does not have subject matter jurisdiction, the U.S. District Court for the District of Delaware or, to the extent such court does not have subject matter jurisdiction, the Superior Court of the State of Delaware, to whose jurisdiction and venue the Parties unconditionally consent and submit. Each Party hereby irrevocably and unconditionally waives any objection to the laying of venue of Claim arising out of this Agreement in such court and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such Claim brought in any such court has been brought in an inconvenient forum. Each Party further agrees that service of any process, summons, notice or document by U.S. registered mail to the respective addresses set forth in Section 9.02 shall be effective service of process for any Claim brought against such Party in any such court.

Section 9.12 Waiver of Jury Trial. EACH PARTY HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR OTHER PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE MERGER. EACH

Exhibit 2.1

PARTY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SUIT OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 9.12.

Section 9.13 Construction. Each of the Parties has participated in the drafting and negotiation of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement must be construed as if it is drafted by all the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of authorship of any of the provisions of this Agreement.

Section 9.14 Certain Debt Financing Provisions. Notwithstanding anything in this Agreement to the contrary, the Company on behalf of itself and each of its controlled Affiliates hereby: (a) agrees that any legal action, whether in law or in equity, whether in contract or in tort or otherwise, involving the Debt Financing Parties, arising out of or relating to, this Agreement, the Debt Financing, or any of the agreements (including, the Debt Letters, any Definitive Agreement or any other document related thereto) entered into in connection with the Debt Financing or any of the transactions contemplated hereby or thereby or the performance of any services thereunder, shall be subject to the exclusive jurisdiction of any federal or state court in the Borough of Manhattan, New York, New York, so long as such forum is and remains available, and any appellate court thereof, and the Company irrevocably submits itself and its property with respect to any such legal action to the exclusive jurisdiction of such court and irrevocably waives, to the fullest extent that it may effectively do so, the defense of an inconvenient forum to the maintenance of such legal action in any such court; (b) agrees that any such legal action shall be governed by and construed in accordance with the Laws of the State of New York (without giving effect to any conflicts of law principles that would result in the application of the laws of another state), except as otherwise provided in any agreement relating to the Debt Financing and except to the extent relating to the interpretation of any provisions in this Agreement (including any provision in any Debt Letter or any Definitive Agreement with respect to the Debt Financing that expressly specifies that the interpretation of such provisions shall be governed by and construed in accordance with any other Law); (c) agrees not to bring or support any legal action, whether in law or in equity, whether in contract or in tort or otherwise, involving the Debt Financing Parties, arising out of or relating to, this Agreement, the Debt Financing, or any of the agreements (including, the Debt Letters, any Definitive Agreement or any other document related thereto) entered into in connection with the Debt Financing or any of the transactions contemplated hereby or thereby or the performance of any services thereunder in any forum other than any federal or state court in the Borough of Manhattan, New York, New York; (d) KNOWINGLY, INTENTIONALLY AND VOLUNTARILY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW TRIAL BY JURY IN ANY LEGAL ACTION BROUGHT AGAINST THE DEBT FINANCING PARTIES IN ANY WAY ARISING OUT OF OR RELATING TO, THIS AGREEMENT, THE DEBT FINANCING, OR ANY OF THE AGREEMENTS (INCLUDING, THE DEBT LETTERS, ANY DEFINITIVE AGREEMENT OR ANY OTHER DOCUMENT RELATED THERETO) ENTERED INTO IN CONNECTION WITH THE DEBT FINANCING OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY OR THE

1.5 Voting. At each meeting of the shareholders every shareholder having the right to vote shall be entitled to vote either in person or by proxy, with one vote for each share held. The shareholders shall take action by the affirmative vote of the holders of the greater of (i) a majority of the voting power of the shares present and entitled to vote on that item of business, or (ii) a majority of the voting power of the minimum number of the shares entitled to vote that would constitute a quorum for the transaction of business at the meeting, except to the extent that the Minnesota Business Corporation Act may require a larger proportion or number.
