AGREEMENT AND PLAN OF MERGER

This Agreement and Plan of Merger is made as of September 13, 2006, by and among GPS CCMP Acquisition Corp., a Delaware corporation (the “Buyer”), GPS CCMP Merger Corp., a Wisconsin corporation (the “Merger Sub”), Generac Power Systems, Inc., a Wisconsin corporation (“Generac”), and Robert D. Kern, as representative of the Shareholders for certain purposes described herein (the “Representative”). The Buyer, the Merger Sub, Generac and the Representative are each referred to in this Agreement as a “Party” and collectively as the “Parties.”

RECITALS

A.            The authorized capital stock of Generac consists of twenty thousand (20,000) shares of Class A Voting Common Stock, par value $0.01 per share (the “Voting Common Stock”), and two hundred thousand (200,000) shares of Class B Nonvoting Common Stock, par value $0.01 per share (the “Nonvoting Common Stock” and, together with the Voting Common Stock, the “Common Stock”).

B.            As of the date of this Agreement, there are 4,000 shares of Voting Common Stock issued and outstanding (the “Voting Common Shares”) and 58,000 shares of Nonvoting Common Stock issued and outstanding (the “Nonvoting Common Shares” and, together with the Voting Common Shares, the “Shares”).

C.            The individuals and trusts listed as Shareholders on Exhibit A hereto (collectively, the “Shareholders” and individually, a “Shareholder”) own all of the issued and outstanding Shares.

D.            The Board of Directors of each of Generac and Buyer, as applicable, deem it to be in the best interests of the Buyer, Generac and the Shareholders to merge the Merger Sub with and into Generac, with Generac being the surviving corporation (the “Merger”), pursuant to the terms of this Agreement and in accordance with Wisconsin Law.

E.             Concurrently with the execution of this Agreement, and as a condition and inducement to Buyer’s and Merger Sub’s willingness to enter into this Agreement, the holder of all of the Voting Common Shares (i) has, pursuant to an action taken by written consent, approved Generac’s execution of this Agreement and its consummation of the transactions contemplated hereby (the “Voting Shares Shareholder Consent”), and (ii) has entered into Support Agreements, for the benefit of the Merger Sub and the Buyer, in substantially the form attached hereto as Exhibit C (the “Support Agreement”).

AGREEMENTS

NOW, THEREFORE, in consideration of the premises and the mutual promises herein made, and in consideration of the representations, warranties and covenants contained herein, the Parties agree as follows.

1.             The Merger.

(a)           The Merger. At the Effective Time, and subject to and upon the terms and conditions of this Agreement and the applicable provisions of Wisconsin Law, the Merger Sub shall be merged with and into Generac, the separate existence of the Merger Sub shall cease, and Generac shall be the surviving corporation (sometimes called the “Surviving Corporation”) and shall continue its corporate existence under the laws of the State of Wisconsin. The name of the Surviving Corporation shall be “Generac Power Systems, Inc.”

(b)           The Closing. Unless this Agreement shall have been terminated pursuant to its terms, the closing of the transactions contemplated by this Agreement (the “Closing”) shall take place at the offices of Reinhart Boerner Van Deuren s.c., at 10:00 a.m., Central Standard Time, on the later of (i) the third Business Day after all of the conditions to the Closing set forth in § 8 hereof are satisfied or waived (in writing) (other than those that by their terms cannot be satisfied prior to the Closing), and (ii) December 31, 2006, but subject to the fulfillment or waiver (in writing) of such conditions at the Closing), or such other date, time and place as shall be agreed upon by Generac, the Buyer and the Merger Sub (the actual date being herein called the “Closing Date”).

(c)           Effective Time. Upon the terms and subject to the conditions of this Agreement, at and in connection with the Closing, the parties hereto shall deliver to the Department of Financial Institutions of the State of Wisconsin (the “DFI”) articles of merger (the “Articles of Merger”), and shall make all other filings or recordings as may be required under Wisconsin Law and any other applicable Law in order to effect the Merger. The Merger shall become effective (the “Effective Time”) upon the filing of the Articles of Merger in the form required by Wisconsin Law and otherwise conforming to the requirements of Wisconsin Law, with the DFI.

(d)           Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement, the Articles of Merger and in the applicable provisions of Wisconsin Law. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, except as otherwise provided herein, all the property, rights, privileges, powers, and franchises of Generac and the Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities, and duties of Generac and the Merger Sub shall become the debts, liabilities, and duties of the Surviving Corporation.

(e)           Articles of Incorporation and By-Laws. At the Effective Time, the Articles of Incorporation and the By-Laws of Generac, as in effect immediately prior to the Effective Time, shall be the Articles of Incorporation and the By-Laws of the Surviving Corporation.

On the Closing Date, the officers and directors listed on § 1(f) of the Disclosure Schedule shall resign, effective as of the Effective Time, from their respective position(s) with Generac set forth on § 1(f) of the Disclosure Schedule.

2.             Merger Consideration; Conversion of Shares.

(a)           Aggregate Consideration. The aggregate consideration payable by the Buyer hereunder (the “Merger Consideration”) shall be the sum of (i) the excess of (A) $2,000,000,000, less (B) the amount of any Transaction Expenses (whether or not then due and payable, and whether or not the same shall have been satisfied and discharged as of the Effective Time), less (C) the amount required to satisfy and discharge in full all liabilities and obligations of Generac under the Amended and Restated Equity Appreciation Share Plan (whether or not the same shall, in fact, have been satisfied and discharged as of the Effective Time). At or prior to the Effective Time, the Buyer shall pay, or cause to be paid, to the Paying Agent an amount equal to the Merger Consideration and the aggregate amount of unpaid Transaction Expenses which the Paying Agent shall pay in accordance with the last sentence of § 2(c)(ii). For purposes of making the payment of the Merger Consideration, not less than three Business Days prior to the Closing Date, Generac shall provide the Buyer and the Merger Sub with a certificate, prepared in good faith, setting forth in reasonable detail Generac’s best estimate of the amount of Transaction Expenses and the Merger Consideration, which estimate shall be in form and substance reasonably acceptable to Buyer. Any such notice delivered by Generac shall be accompanied by supporting documentation (including final bills and/or invoices from Generac’s counsel, advisors, consultants, investment bankers and accountants, to the extent constituting Transaction Expenses) reasonably acceptable to Buyer.

(b)           Conversion of Shares. At the Effective Time, by virtue of the Merger and without any action on the part of the Buyer, the Merger Sub, Generac, the Representative or the Shareholders, pursuant to this Agreement and Wisconsin Law, subject to the other provisions of this § 2:

(i)            Each of the outstanding Shares shall be converted into the right to receive an amount in cash, without interest thereon, equal to the Merger Consideration less the Representative’s Escrow, divided by 62,000 (the number of outstanding Shares) (the “Per Share Merger Consideration”), payable to the holder thereof upon surrender of the certificate representing such Share. As of the Effective Time, all outstanding Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of a certificate representing any outstanding Shares shall cease to have any rights with respect thereto, except the right to receive the Per Share Merger Consideration in respect thereof.

(ii)           Each share of common stock, par value $0.01 per share, of the Merger Sub (the “Merger Sub Common Stock”), issued and outstanding immediately prior to the Effective Time, shall be converted into and exchanged for one validly issued, fully paid and non-assessable share of voting common stock, par value $0.01 per share, of the Surviving Corporation (the “Surviving Corporation Common Stock”). From and after the Effective Time, each outstanding certificate which represented shares of the Merger Sub Common Stock shall evidence ownership of and represent the number of shares of Surviving Corporation Common Stock into which such shares of the Merger Sub Common Stock shall have been converted pursuant to this § 2(b)(ii).

(iii)          All Shares held in Generac’ s treasury as of the Effective Time shall be cancelled and retired and all rights in respect thereof shall cease to exist, without any conversion thereof or payment of any consideration therefor.

3

(c)                                  Payments; Payment for Shares; Lost Certificates.

(i)                                     Immediately following the Effective Time, the Buyer shall deposit, or shall cause to be deposited, with a bank or trust company organized under the laws of, and having an office in, the United States and jointly agreed upon in writing by the Buyer and the Representative (the “Paying Agent”), for the benefit of the Shareholders and for exchange and payment pursuant to this § 2 through the Paying Agent, cash in an amount equal to the Merger Consideration (such funds being hereinafter referred to as the “Payment Fund”). Upon the making of such payments to the Paying Agent, the Buyer, the Merger Sub and the Surviving Corporation shall thereafter have no further liability to any Shareholder for payment for any of the Shares. The Paying Agent shall, pursuant to irrevocable written instructions executed by the Representative, deliver out of the Payment Fund all amounts received by the Paying Agent for the account of the Shareholders, except to the extent paid into the Representative’s Escrow. The Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any Shareholder such amounts as are required to be deducted and withheld with respect to the making of such payment under the Code, and the rules and regulations promulgated thereunder, or any provision of any state, local or foreign tax law. To the extent such amounts are so withheld, such withheld amounts shall be deemed for all purposes of this Agreement as having been paid to the holder of the Shares in respect to which such deduction and withholding was made. On the Closing Date, the Representative shall provide the Paying Agent written instructions setting forth the amount of the Payment Fund that shall be paid by the Paying Agent into a separate escrow account for the benefit of the Representative to pay for expenses incurred by the Representative in connection with actions taken as the Representative (the “Representative’s Escrow”). The Representative’s Escrow shall include the Withholding Amount.

(ii)                                  At or prior to the Effective Time, (A) each Shareholder who held at the Effective Time an outstanding certificate or certificates that represented outstanding Shares (the “Certificates”) shall surrender such Certificates to the Paying Agent, together with a completed and duly executed letter of transmittal that shall be in form and substance reasonably satisfactory to the Representative and the Buyer and, in any event, shall include a waiver of appraisal rights and a release (a “Letter of Transmittal”), (B) upon such surrender of a Certificate and Letter of Transmittal or at the Effective Time, whichever is later, the holder thereof will be entitled to receive an amount equal to (1) the number of Shares represented by such Certificate, multiplied by (2) the Per Share Merger Consideration, payable by wire transfer of immediately available funds on the Closing Date, immediately following the Effective Time, to an account designated in writing by such Shareholder no later than two (2) Business Days prior to the Closing Date, (C) the Paying Agent shall immediately pay such amounts to such holder and (D) the Certificates so surrendered shall be cancelled; provided, however, in the case of any Shareholder with respect to which the Representative provides the Paying Agent with written instructions in accordance with the last two sentences of § 2(c)(i), the amount payable to such Shareholder shall be reduced by the Withholding Amount applicable to such Shareholder, which amount shall have been paid to the Representative’s Escrow pursuant to § 2(c)(i). No interest will be paid or accrue on the Merger Consideration

4

payable upon the surrender of the Certificates. Subject to § 2(c)(iv), under no circumstances will any holder of a Certificate be entitled to receive any part of the Merger Consideration until such holder shall have surrendered such Certificate. On the Closing Date, the Paying Agent shall also pay by wire transfer of immediately available funds, the unpaid Transaction Expenses, pursuant to written instructions from the Representative and the Surviving Corporation.

(iii)                               If payment is to be made to a Person other than the Person in whose name a surrendered Certificate is registered, the Certificate must be properly endorsed or otherwise in proper form for transfer and the Person requesting such payment must agree to pay any applicable transfer or other taxes or establish to the reasonable satisfaction of the Buyer and the Surviving Corporation that such tax has been paid or is not applicable.

(iv)                              If any Certificate has been lost, stolen or destroyed, the Buyer will issue the applicable portion of the Aggregate Consideration deliverable in respect thereof upon receipt of a customary affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed. After the Effective Time, until surrendered in accordance with these provisions, each Certificate shall represent only the right to receive the applicable portion of the Merger Consideration as set forth in this Agreement.

(v)                                 After the Effective Time, there shall be no transfers on the stock transfer books of the Surviving Corporation of the Shares which were outstanding immediately prior to the Effective Time. Certificates presented to the Surviving Corporation after the Effective Time shall be cancelled.

(vi)                              Any portion of the Payment Fund that remains undistributed to the Shareholders for six months after the Effective Time shall be delivered to the Buyer upon demand, and any Shareholder who has not theretofore complied with this §2 shall thereafter look only to the Buyer for payment of such Shareholder’s claim to any part of the Merger Consideration. None of the Buyer, the Merger Sub or the Surviving Corporation shall be liable to any Person in respect of any Merger Consideration delivered to a public office pursuant to any applicable abandoned property, escheat or similar law. If any Certificates representing outstanding Shares shall not have been surrendered immediately prior to the date on which any Merger Consideration in respect of such Certificate would otherwise escheat to or become the property of any government authority, any such Merger Consideration in respect of such Certificate shall, at such time and the extent permitted by applicable law, become the property of the Surviving Corporation, free and clear of all claims of interest of any person previously entitled thereto.

3.                                       Representations and Warranties of Generac. Generac hereby represents and warrants to the Buyer that the statements contained in this §3 are correct and complete as of the date of this Agreement and shall be correct and complete as of the Closing Date, except as set forth in the corresponding section of the disclosure schedule accompanying this Agreement (the “Disclosure Schedule”). The Disclosure Schedule shall be arranged in paragraphs corresponding to the lettered paragraphs contained in this §3; provided, however, that any event, fact or circumstance disclosed in any lettered paragraph of the Disclosure Schedule shall be deemed to

5

be a disclosure for purposes of other lettered paragraphs of the Disclosure Schedule so long as it is reasonably apparent that such disclosure applies to such other lettered paragraphs of the Disclosure Schedule.

(a)                                  Organization; Authorization of Transaction. Generac is a corporation duly organized, validly existing and in good standing under the laws of the State of Wisconsin. Generac is duly authorized to conduct business and is in good standing under the laws of each jurisdiction set forth in §3(b) of the Disclosure Schedule, and, except where the lack of such qualification would not have a Material Adverse Effect, there are no other jurisdictions where Generac is required to be so qualified. Generac has full corporate power and authority to carry on the businesses in which it is engaged and to own and use the properties owned and used by it. Generac has full corporate power and authority to execute and deliver this Agreement and to perform its obligations hereunder. This Agreement constitutes the valid and legally binding obligation of Generac, enforceable in accordance with its terms and conditions, except as enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally or by general equitable principles. The Voting Shares Shareholder Consent and any required consents under the Shareholders’ Agreements (each of which will be terminated at or prior to Closing) are the only consent or approval of the holders of the capital stock of Generac required under Wisconsin Law and the Organizational Documents of Generac in connection with the execution, delivery and performance by Generac of this Agreement and the consummation of the transactions contemplated hereby.

(b)                                 Noncontravention. Except as set forth in §3(b) of the Disclosure Schedule as to the Shareholders’ Agreements, neither the execution and the delivery of this Agreement, nor the consummation of the transactions contemplated hereby, shall (i) violate any statute, regulation, rule, injunction, judgment, order, decree or ruling of any government, governmental agency or court to which any of the Shareholders or Generac is subject or any provision of the Organizational Documents of any of the Shareholders or Generac or (ii) conflict with, result in a breach of, constitute a default under, result in the acceleration of, create in any party the right to accelerate, terminate, modify or cancel, or require any notice under any agreement, contract, lease, license or instrument to which any of the Shareholders or Generac is a party or by which any of them are bound or to which any of their assets are subject, except where such violation, conflict, breach, default, acceleration, termination, modification, cancellation or failure to give notice would not have a Material Adverse Effect or a material adverse effect on the ability of the Shareholders or Generac to consummate the transactions contemplated by this Agreement. Except for applicable requirements of the Hart-Scott-Rodino Act and for the filing of the Articles of Merger with the DFI under Wisconsin Law, none of the Shareholders nor Generac is required to give any notice to, make any filing with, or obtain any authorization, consent or approval of any government or governmental agency in order to consummate the transactions contemplated by this Agreement, except where the failure to give notice, to file or to obtain any authorization, consent or approval would not have, or would not reasonably be likely to have (individually or in the aggregate) a Material Adverse Effect or a material adverse effect on the ability of the Shareholders or Generac to consummate the transactions contemplated by this Agreement.

(c)                                  Brokers’ Fees. Neither the Shareholders nor Generac has any liability or obligation to pay any fees or commissions to any broker, finder or investment banker with respect to the transactions contemplated by this Agreement for which the Buyer could become

6

liable or obligated, except for the fees of Goldman Sachs & Co. and Wells Fargo Securities, LLC, which shall be part of the Transaction Expenses.

(d)                                 Capitalization. §3(d) of the Disclosure Schedule sets forth for Generac (i) the number of shares of authorized capital stock of each class of its capital stock (and their respective par values), (ii) the number of issued and outstanding shares of each class of its capital stock, the names of the holders thereof, and the number of shares held by each such holder, and (iii) its directors and officers. No shares of Generac’s preferred stock are outstanding. All of the issued and outstanding shares of capital stock of Generac have been duly authorized and are validly issued, fully paid and nonassessable (subject to §180.0622(2)(b) of Wisconsin Law, as judicially interpreted, for debts owing to employees for services performed, but not exceeding six months’ service in any one case) and were not issued in violation or contravention of any preemptive or similar rights. Each Shareholder holds of record all of the Shares of Generac set forth next to such Shareholder’s name in §3(d) of the Disclosure Schedule, free and clear of any restrictions on transfer, Security Interests and Permitted Liens (other than restrictions under the Securities Act, state securities laws and the Shareholders’ Agreements). Except as set forth on §3(d) of the Disclosure Schedule, there are no outstanding or authorized options, warrants, purchase rights, subscription rights, conversion rights, exchange rights or other contracts, instruments or commitments that could require any Shareholder to sell, transfer or otherwise dispose of any capital stock of Generac or that could require Generac to issue, sell or otherwise cause to become outstanding any of its capital stock (in each case, other than this Agreement and the Shareholders’ Agreements). Except as set forth on §3(d) of the Disclosure Schedule, there are no outstanding stock appreciation, phantom stock or similar rights with respect to Generac. There are no voting trusts, proxies or other agreements or understandings with respect to the voting of any capital stock of Generac.

(e)                                  Subsidiaries and Joint Ventures. Except as set forth in § 3(e) to the Disclosure Schedule, Generac has no Subsidiaries and is not a partner or member of any partnership, joint venture or other similar relationship.

(f)                                    Financial Statements. Attached hereto as Exhibit B are the following financial statements (collectively the “Financial Statements”): (i) Generac’s audited balance sheets and statements of income, stockholders’ equity and cash flows as of and for the years ended December 31, 2004 and 2005 (the “Most Recent Fiscal Year End”) and (ii) Generac’s unaudited balance sheet and statements of income and cash flows (the “Most Recent Financial Statements”) as of and for the period beginning January 1, 2006 and ended June 30, 2006 (the “Most Recent Fiscal Month End”).

(g)                                 Title to Personal Property. Except as set forth on §3(g) of the Disclosure Schedule, Generac has good and valid title to, or a valid leasehold interest in, the material tangible personal property that is reflected on the Most Recent Balance Sheet, free and clear of any Security Interest. To the Knowledge of Generac, all such items of material tangible personal property are in good condition and in a state of good maintenance and repair (ordinary wear and

7

tear excepted) and are adequate for the conduct of the businesses of Generac in substantially the same manner in which such businesses are currently being conducted.

(h)                            Absence of Certain Developments. Except as set forth on §3(h) of the Disclosure Schedule or otherwise contemplated by this Agreement, since the Most Recent Fiscal Month End, there has not occurred, and there is no event, circumstance or occurrence that is reasonably likely to have (individually or in the aggregate), any Material Adverse Effect.

(a)           General. In the event that at any time after the Closing any further action is necessary to carry out the purposes of this Agreement, each of the Parties shall take such further action (including the execution and delivery of such further instruments and documents) as the

22

other Party may reasonably request, all at the sole cost and expense of the requesting Party. The Buyer agrees to retain records relating to Generac for the period prior to the Closing and make them available to the Representative for a period of five years after the Closing, or, in the alternative, to notify the Representative in writing at least 30 days prior to of their disposal at any time prior to the expiration of such period and permit the Representative to have access to such records.

(c)           Transition. Neither the Representative nor Generac shall take any action that is designed or intended to have the effect of discouraging any lessor, licensor, customer, supplier or other business associate of Generac from maintaining the same business relationships with the Buyer and Generac after the Closing as it maintained with Generac prior to the Closing.

(d)           Tax Matters.

(i)            The Representative shall properly prepare or cause to be properly prepared, and timely file or cause to be filed, all Tax Returns of or with respect to Generac that are required to be filed on or before the Closing Date and Generac’s final S corporation returns (other than any Tax Returns on which there are reflected Section 338(h)(10) Taxes), and shall timely pay or cause to be timely paid all Taxes shown due thereon. All such Tax Returns shall be prepared in a manner consistent with this Agreement and prior practice unless otherwise required by applicable Tax Law, it being understood that the payments made pursuant to the Employment and Deferred Compensation Agreements with the individuals listed on Schedule 5(l)(ii) and the Generac Power Systems, Inc. Amended and Restated Equity Appreciation Plan are deemed to occur prior to the Closing and the parties agree to report such items in the taxable period that ends on the Closing Date (or on the preclosing portion of a Straddle Period, as the case may be). The Representative shall provide Buyer with copies of completed drafts of such Tax Returns (along with supporting workpapers) at least twenty (20) days prior to the due date for filing thereof, for Buyer’s review and approval (which approval shall not be unreasonably withheld or delayed). The Buyer shall prepare or cause to be prepared, and file or cause to be filed, all other Tax Returns required to be filed by the Surviving Corporation and shall timely pay or cause to be timely paid all Taxes of Generac shown due thereon; provided that any Tax Return with respect to (A) any taxable period that includes (but does not end on) the Closing Date (a “Straddle Period”) and (B) any taxable period that ends on or prior to the Closing Date on which are reflected Taxes that are due and payable by the Shareholders shall be prepared consistently with prior practice unless otherwise required by applicable Tax law and shall

23

be provided by the Buyer to the Representative for review and approval at least twenty (20) days before due (including extensions) (which approval shall not be unreasonably withheld or delayed).

(ii)           From and after the Closing Date, the Representative and the Buyer shall give prompt notice to each other of any Tax authority’s proposed adjustment to Income Taxes of or with respect to Generac for all Tax periods that end on or prior to the Closing Date or any Straddle Period. The Representative shall have the right to represent and control the interests of Generac in any Income Tax audit or administrative or court proceeding relating to taxable periods of Generac which end on or before the Closing Date and to employ counsel of its choice at the Shareholders’ expense; provided, however, that the Buyer shall have the right to participate in, and consult with the Representative regarding, any such contest that may affect Generac or the Surviving Corporation for any periods ending after the Closing Date, or for any periods with respect to Section 338(h)(10) Taxes, at Buyer’s own expense; provided further that the Representative shall not settle any contests referred to in the immediately preceding proviso without the prior written consent of Buyer, which consent shall not be unreasonably withheld or delayed. Notwithstanding the foregoing, the Buyer should have the exclusive right to represent the interests of Generac in such contest if such contest is with respect to any Section 338(h)(10) Taxes. The Buyer shall control the conduct of any audit or proceeding involving Generac or the Surviving Corporation for periods that end after the Closing Date, including any Straddle Period. The Buyer shall keep the Representative reasonably informed of the progress of any such audit or other proceeding, and the Representative shall cooperate with the Buyer and the Surviving Corporation in the conduct of any such audit or other proceeding. Notwithstanding anything in this Agreement to the contrary, the Buyer and the Surviving Corporation shall not resolve, settle, compromise, or abandon any issue or claim without the prior written consent of the Representative (on behalf of the Shareholders) if such action would materially and adversely affect the Tax liabilities of any of the Shareholders for any period ending on or before the Closing Date or the pre-Closing portion of any Straddle Period (including any imposition of any income Tax deficiencies), which consent may not be unreasonably withheld or delayed.

(iii)          Neither the Buyer nor the Surviving Corporation may amend or cause the amendment of an Income Tax Return of Generac, change an annual accounting period, adopt or change any Income Tax accounting method, or file or amend any Income Tax election concerning Generac with respect to any period ending on or prior to the Closing Date without the written consent of the Representative, which consent may not be unreasonably withheld or delayed. The Surviving Corporation shall (and the Buyer shall cause the Surviving Corporation to comply), upon request by the Representative and at the Representative’s expense, cooperate in the preparation of and submission to the proper Tax authority of any amended Income Tax Return with respect to Generac for any taxable period ending on or before the Closing Date.

(iv)          Any refund of Income Taxes of Generac (including any interest with respect thereto) attributable (or treated as attributable) to any period that ends on or before the Closing Date (including the pre-Closing portion of a Straddle Period) and for

24

which the Shareholders would be responsible in the event a deficiency were assessed, shall be the property of the Shareholders, and if received by the Buyer, the Surviving Corporation or any other affiliated entity of the Buyer, the Buyer shall promptly pay such refund to the Representative.

(v)           The Buyer shall join with the Shareholders in making an election under section 338(h)(10) of the Code (and any corresponding elections under appropriate state, local or foreign laws, to the extent permitted by such laws) with respect to the Merger. The Representative shall cause five (5) IRS Forms 8023 and any other appropriate election forms to be properly prepared, executed by the Shareholders and submitted to the Buyer prior to the Closing Date. The Buyer shall execute and timely file such election forms with the appropriate taxing authorities. The Shareholders and the Buyer shall file all Tax Returns in a manner consistent with the Code section 338(h)(10) election and will not take any position contrary thereto.

(vi)          The Buyer, Generac, the Shareholders and the Surviving Corporation, as applicable, shall reasonably cooperate, as and to the extent reasonably requested by any such party, in connection with the furnishing of information relating to and the filing of Tax Returns of Generac and the Surviving Corporation and any audit, litigation or other proceeding with respect to Taxes of Generac or the Surviving Corporation. Subject to § 6(d), such cooperation shall include signing any Tax Return, amended Tax Returns, claims or other documents necessary to settle any Tax controversy, the retention and (upon the other party’s request) the provision of records and information which are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Buyer, Generac, the Shareholders and the Surviving Corporation agree to retain all books and records with respect to Tax matters pertinent to Generac relating to any taxable period beginning before the Closing Date until a reasonable time after the expiration of the statute of limitations of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority.

(vii)         Neither the Shareholders nor Generac shall [a] revoke Generac’s election to be taxed as an S corporation within the meanings of §1361 of the Code or any analogous or similar provision of state or local Tax Law, or [b] take or allow any action that would result in the termination of Generac’s status as a validly existing S corporation within the meaning of §1361 of the Code or any analogous or similar provision of state or local Tax Law prior to the Closing.

(viii)        The Parties agree that, after the Closing Date, the Surviving Corporation will be obligated to remit Wisconsin income tax withholding for Shareholders who are not residents of the state of Wisconsin (the “Nonresident Shareholders”) with respect to the flow through income of Generac for the tax year ending on the Closing Date, as required by Wisconsin Statutes section 71.775 (the “Wisconsin Withholding”). The Representative shall reimburse the Surviving Corporation for the Wisconsin Withholding pursuant to the procedure set forth in this §6(d)(viii) and may use funds from the Representative’s Escrow for this purpose. At least 10 days prior to the due date of

25

Generac’s S corporation Tax Return for the tax year ending on the Closing Date, the Representative shall provide notice (the “Withholding Notice”) to the Surviving Corporation of the names and addresses of the Nonresident Shareholders, the amount of the Wisconsin Withholding (the “Withholding Amount”) and due date of the Wisconsin Withholding (the “Withholding Due Date”), which Withholding Notice (including the Withholding Amounts set forth therein) shall be reasonably satisfactory to Buyer and the Surviving Corporation. The Withholding Notice shall be accompanied by a payment equal to the Withholding Amount from the Representative to the Surviving Corporation. The Surviving Corporation shall thereafter remit the Withholding Amount on behalf of the Nonresident Shareholders to the Wisconsin Department of Revenue by the Withholding Due Date. Except to the extent caused by the action or inaction of the Shareholders or the Representative, neither the Shareholders nor the Representative will be liable for any penalties, interest or other assessments resulting from the Surviving Corporation’s failure to pay the Withholding Amount by the Withholding Due Date and the Surviving Corporation shall be liable for any amounts payable as a result of such failure.

(ix)           Buyer shall not permit the Surviving Corporation to take any actions on the Closing Date that are out of the Ordinary Course of Business of Generac and that have the result of increasing the taxable income allocated to the Shareholders for the period ending on the Closing Date, except for any actions that are expressly contemplated by the Merger Agreement.

(e)          Allocation of Purchase Price. The parties hereto agree that the Merger Consideration and the liabilities of Generac (plus other relevant items) will be allocated to the assets of Generac for all purposes (including Tax and financial accounting purposes (unless, with respect to financial accounting, the Surviving Corporation’s auditors determine that a different allocation is required by GAAP)) as provided on Schedule 6(e), as may be amended by the joint agreement of the Buyer and the Representative in good faith to reflect the operations of Generac through the Closing Date. The Buyer, Generac and the Shareholders shall file all Tax Returns (including amended returns and claims for refund) and information reports in a manner consistent with Schedule 6(e), as may be amended as set forth above, and will not take any position contrary thereto.

(f)          Dispute Resolution. In the event that Representative or Buyer disputes the application or interpretation of any provision of Sections 6(d) or (e), such party shall deliver to the other a statement setting forth, in reasonable detail, the nature of any disagreement so asserted. The parties shall attempt in good faith to resolve any such dispute within twenty (20) days following the date of the statement provided pursuant to the preceding sentence. If the parties are unable to resolve such dispute within such twenty (20) day period, the dispute shall be resolved by KPMG LLP (the “Selected Accounting Firm”). The Selected Accounting Firm shall finally and conclusively resolve any dispute relating to matters set forth in Sections 6(d) or (e) or within thirty (30) days following receipt of the submission. The Selected Accounting Firm shall determine, only with respect to the specific disagreements submitted in writing by a Representative and Buyer, the manner in which such item or items in dispute should be resolved. The Selected Accounting Firm shall be directed to make such determination promptly, but in no event later than thirty (30) days after acceptance of its appointment. Any finding by the Selected

26

Accounting Firm shall be a reasoned award stating the findings of fact and conclusions of Law (if any) on which it is based, shall be final and binding upon the parties and shall be the sole and exclusive remedy between the parties regarding the disputed items so presented. The fees and expenses of the Selected Accounting Firm shall be shared by the Representative and Buyer equally, and the parties shall otherwise bear their own expenses incurred in any dispute resolution pursuant to this Section 6(f). If any dispute with respect to a Tax Return is not resolved prior to the due date of such Tax Return, such Tax Return shall be filed in the manner which the party responsible for filing such Tax Return deems correct and shall be promptly amended to reflect the resolution of any such dispute (whether determined by the Selected Accounting Firm or otherwise by agreement of the parties).

(g)           Directors’ and Officers’ Indemnification and Insurance.

(i)            Without limiting any additional rights that any officer or director may have under any Plan, Generac’s Articles of Incorporation, as amended, or By-Laws, as amended, or any indemnification agreement between Generac and its directors and officers in effect as of the date hereof, from and after the Effective Time, the Buyer shall, and shall cause the Surviving Corporation to, indemnify and hold harmless each present (as of the Effective Time) and former officer or director of Generac (each, an “Indemnified Party” and, collectively, the “Indemnified Parties”), against all claims, losses, liabilities, damages, judgments, inquiries, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of actions taken by them in their capacity as officers or directors at or prior to the Effective Time (including, to the extent indemnifiable thereunder, this Agreement and the transactions contemplated hereby), or taken by them at the request of Generac, whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent permitted under applicable Wisconsin Law for a period of six years from the Effective Time. Each Indemnified Party shall be entitled to advancement of expenses incurred in the defense of any claim, action, suit, proceeding or investigation from the Surviving Corporation within 10 Business Days of receipt by the Surviving Corporation from the Indemnified Party of a request therefor; provided, however, that any Indemnified Party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such person is not entitled to indemnification. The Surviving Corporation shall not settle, compromise or consent to the entry of any judgment in any proceeding or threatened action, suit, proceeding, investigation or claim and in which indemnification could be sought by such Indemnified Party hereunder, without the consent of such Indemnified Party, which consent shall not be unreasonably withheld, conditioned or delayed, unless such settlement, compromise or consent includes an unconditional release of such Indemnified Party from all liability arising out of such action, suit, proceeding, investigation or claim.

(ii)           The Articles of Incorporation and By-Laws of the Surviving Corporation (or any successor to the Surviving Corporation) will contain provisions with respect to exculpation, indemnification and the advancement of expenses that are at least as favorable to the Indemnified Parties as those contained in the Articles of Incorporation, as amended, and By-Laws, as amended, of Generac as in effect on the date hereof, which

27

provisions will not, except as required by applicable law, be amended, repealed or otherwise modified in any manner that would adversely affect the rights thereunder of any Indemnified Party unless the Surviving Corporation (or any successor to the Surviving Corporation) provides other assurance sufficient to ensure the continued exculpation, indemnification and advancement of expenses of the Indemnified Parties for six years to the fullest extent of the law as provided in such Articles of Incorporation, as amended, and By-Laws prior to any such amendment, repeal or modifications.

(iii)          Prior to the Effective Time, Generac shall obtain and fully pay for “tail” insurance policies with a claims period of at least six years from the Effective Time from an insurance carrier with an AM Best rating of A- or better with respect to directors’ and officers’ liability insurance and fiduciary liability insurance with benefits and levels of coverage at least as favorable as Generac’s existing policies with respect to matters existing or occurring at or prior to the Effective Time (including in connection with this Agreement or the transactions contemplated hereby); provided that Generac shall use commercially reasonable efforts to minimize the cost of such “tail” insurance policy (it being understood that Generac shall not be required to accept a reduction in the quality of the insurer providing such policy or the scope of the coverage of such policy as compared to Generac’s existing insurer and policy); and provided, further, that the cost of such “tail” insurance policy shall not exceed 300% of the current annual premiums paid by Generac for such insurance (the “D&O Cap”); and provided, further, that in no event shall the costs of any such “tail” insurance policy be deemed to constitute Transaction Expenses for any purposes of this Agreement. If the Buyer and the Surviving Corporation cannot obtain such “tail” insurance policies as of the Effective Time for less than the D&O Cap, the Buyer and the Surviving Corporation shall obtain a “tail” insurance policy providing benefits and levels of coverage that are available for the amount of the D&O Cap. The Surviving Corporation shall honor and perform under all indemnification agreements entered into by Generac.

(iv)          This §6(g) is intended to be for the benefit of, and shall be enforceable by, the Indemnified Parties, their heirs and personal representatives and shall be binding on the Surviving Corporation and their successors and assigns.

7.             Appointment of the Representative.

Kern as the Representative to act as such Person’s true and lawful attorney-in-fact and agent and authorizes the Representative acting for such Person and in such Person’s name, place and stead, in any and all capacities to do and perform every act and thing required or permitted to be done in connection with the transactions contemplated by this Agreement, as fully to all intents and purposes as such Person might or could do in person, including, without limitation:

If William W. Treffert acts as the Representative pursuant hereto, he shall provide written notice to the Buyer that he is acting in such capacity.

(b)         Liability of the Representative. The Representative shall not have by reason of this Agreement a fiduciary relationship in respect of any Shareholder. The Representative shall not be liable to any Shareholder for any action taken or omitted by it or him hereunder or under any other document hereunder, or in connection therewith, except that the Representative shall not be relieved of any liability imposed by law for gross negligence or willful misconduct. The Representative shall not be liable to any Shareholder for any apportionment or distribution of payments made by it in good faith, and if any such apportionment or distribution is subsequently determined to have been made in error, the sole recourse of any Shareholder to whom payment was due, but not made, shall be to recover from other Shareholders any payment in excess of the amount to which they are determined to have been entitled. The Representative shall not be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement. Each of the Shareholders acknowledges and agrees that the Representative shall not be obligated to take any actions and shall be entitled to take such actions as the Representative deems appropriate in such Representative’s sole discretion.

29
