     WHEREAS, immediately following the Merger, the surviving corporation in the Merger shall merge with and into Merger LLC (the “Subsequent Merger”) in accordance with Section 1.3, upon the terms and subject to the conditions of this Agreement and in accordance with the Illinois Limited Liability Company Act (the “LLC Act”);

     WHEREAS, the Parties intend that the Merger be mutually interdependent with and a condition precedent to the Subsequent Merger and that the Subsequent Merger shall, through the binding commitment evidenced by Section 1.3(a), be effectuated immediately following the Effective Time (as defined below), upon the terms and subject to the conditions of this Agreement and in accordance with the LLC Act, without further approval, authorization or direction from or by any of the Parties hereto;

     WHEREAS, the Board of Directors of the Company (the “Company Board”) has, upon the terms and subject to the conditions set forth herein, (i) determined that the transactions contemplated by this Agreement, including the Merger, are fair to and in the best interests of the Company and its shareholders, and (ii) approved and declared advisable this Agreement and the transactions contemplated hereby, including the Merger;

     WHEREAS, the Boards of Directors of Parent (the “Parent Board”) and Merger Sub and the sole member of Merger LLC have, upon the terms and subject to the conditions set forth herein, (i) determined that the transactions contemplated by this Agreement, including the Merger and the Subsequent Merger, are fair to and in the best interests of Parent and Merger Sub and their respective shareholders, (ii) approved and declared advisable this Agreement and the transactions contemplated hereby, including the Merger and the Subsequent Merger and (iii) in the case of the Parent Board, recommended that Parent’s shareholders adopt the Charter Amendment;

     WHEREAS, it is intended that the Merger and the Subsequent Merger, considered together as a single integrated transaction for U.S. federal income tax purposes, and along with the other transactions effected pursuant to this Agreement, shall qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement will be, and hereby is, adopted as a “plan of reorganization” within the meaning of Treasury Regulation Sections 1.368-2(g) and 1.368-3(a); and

     WHEREAS, Parent, Merger Sub, Merger LLC and the Company desire to make certain representations, warranties, covenants and agreements in connection with the Merger and also to prescribe various conditions to the Merger.

AGREEMENT

     NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements contained in this Agreement and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, and subject to the conditions set forth herein, the Parties to this Agreement agree as follows:

ARTICLE 1
THE MERGER

          1.1 The Merger.

               (a) Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the IBCA, at the Effective Time, Merger Sub shall be merged with and into the Company. As a result of the Merger, the separate corporate existence of Merger Sub shall cease, and the Company shall continue as the surviving corporation of the Merger (the “Surviving Corporation”). At the Effective Time, the effects of the Merger shall be as provided in this Agreement and the applicable provisions of the IBCA. Without limiting the generality of the foregoing, at the Effective Time, all of the property, rights, privileges, immunities, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all of the debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

               (b) At the Effective Time, the articles of incorporation of Merger Sub as in effect immediately prior to the Effective Time shall be the articles of incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or herein or by applicable Law. In addition, at the Effective Time, the bylaws of Merger Sub as in effect immediately prior to the Effective Time shall be the bylaws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law.

               (c) The Parties shall take all actions necessary so that the directors of Merger Sub immediately prior to the Effective Time shall, from and after the Effective Time, be the initial directors of the Surviving Corporation, each to hold office in accordance with the articles of incorporation and bylaws of the Surviving Corporation

until their respective successors shall have been duly elected, designated or qualified, or until their earlier death, resignation or removal in accordance with the articles of incorporation and bylaws of the Surviving Corporation. The officers of the Company immediately prior to the Effective Time, from and after the Effective Time, shall continue as the officers of the Surviving Corporation, each to hold office in accordance with the articles of incorporation and bylaws of the Surviving Corporation until their respective successors shall have been duly elected, designated or qualified, or until their earlier death, resignation or removal in accordance with the articles of incorporation and bylaws of the Surviving Corporation.

               (d) After the Effective Time, if the Surviving Corporation shall determine or shall be advised that any deeds, bills of sale, instruments of conveyance, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm of record or otherwise in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of either of the Company or Merger Sub acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger or otherwise to carry out this Agreement, then the officers and directors of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of either the Company or Merger Sub, all such deeds, bills of sale, instruments of conveyance, assignments and assurances and to take and do, in the name and on behalf of each of such corporations or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title or interest in, to and under such rights, properties or assets in the Surviving Corporation or otherwise to carry out this Agreement.

          1.2 Closing and Effective Time of the Merger. The closing of the Merger (the “Closing”) will take place at 9:00 a.m., Chicago, Illinois time, on the date that is the later of (i) the third Business Day after satisfaction or waiver of all of the conditions set forth in Article 6 (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions at the Closing) and (ii) the final day of the Marketing Period or such earlier date as may be specified by Parent on no less than three Business Days’ prior notice to the Company (such date on which the Closing occurs, the “Closing Date”), at the offices of Latham & Watkins LLP, 233 South Wacker Drive, Suite 5800, Chicago, Illinois 60606, unless another time, date or place is agreed to in writing by the Parties hereto. On the Closing Date, or on such other date as Parent and the Company may agree to in writing, (i) Parent, Merger Sub and the Company shall cause appropriate articles of merger or other appropriate documents (the “Articles of Merger”) to be executed and filed with the Secretary of State of the State of Illinois in accordance with the relevant provisions of the IBCA and shall make all other filings or recordings required under the IBCA and (ii) Parent shall file the Charter Amendment with the Secretary of State of Georgia. The Merger shall become effective at the time the Articles of Merger shall have been duly filed with the Secretary of State of the State of Illinois or such other date and time as is agreed upon by the Parties and specified in the Articles of Merger, such date and time hereinafter referred to as the “Effective Time”.

          1.3 Subsequent Merger.

               (a) Immediately after the Effective Time, the Surviving Corporation shall merge with and into Merger LLC, the separate corporate existence of the Surviving Corporation shall thereupon cease, Merger LLC shall continue as the surviving entity (the “Surviving Company”) and all of the rights and obligations of the Surviving Corporation under this Agreement shall be deemed the rights and obligations of the Surviving Company. The effects of the Subsequent Merger shall be as provided in this Agreement and the applicable provisions of the LLC Act. Immediately following the completion of the Subsequent Merger, the Articles of Organization and Operating Agreement of the Surviving Company shall be as mutually agreed by Parent and the Company prior to filing the Joint Proxy Statement with the SEC.

               (b) The Merger and Subsequent Merger, taken together as a single integrated transaction for U.S. federal income tax purposes, and along with the other transactions effected pursuant to this Agreement, are intended to be treated for U.S. federal income tax purposes as a “reorganization” under Section 368(a) of the Code (to which each of Parent and the Company are to be parties under Section 368(b) of the Code) in which the Company is to be treated as merging directly with and into Parent, with the Company Common Stock converted in such merger into the right to receive the consideration provided for hereunder. This Agreement shall constitute a “plan of reorganization” within the meaning of Treasury Regulation Sections 1.368-2(g) and 1.368-3(a).

               (c) Each of the Parties hereto shall, and shall cause its affiliates to, treat the Merger and Subsequent Merger for all Tax purposes consistent with Section 1.3(b) unless required to do otherwise by applicable Law.

ARTICLE 2
EFFECT OF THE MERGER ON CAPITAL STOCK

          2.1 Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of any of the following securities:

               (a) Conversion of Common Stock. Subject to Section 2.2, each share of common stock, par value $2.50 per share, of the Company (a “Share” or collectively, the “Shares”) issued and outstanding immediately prior to the Effective Time, other than Shares to be cancelled in accordance with Section 2.1(c) and other than Dissenting Shares, shall be converted into the right to receive (i) $21.20 in cash, without interest (the “Cash Consideration”), and (ii) 0.8382 (the “Exchange Ratio”) of a share of validly issued, fully paid and nonassessable shares of Parent Common Stock (the “Stock Consideration” and, together with the Cash Consideration, the “Merger Consideration”).

               (b) Effect on Common Stock. At the Effective Time, all of the Shares shall cease to be outstanding, shall be cancelled and shall cease to exist, and each certificate (a “Certificate”) formerly representing any of the Shares (other than Shares to

be cancelled in accordance with Section 2.1(c) and other than Dissenting Shares) shall thereafter represent only the right to receive the Merger Consideration and any other amounts as provided in Section 2.2, in each case without interest, subject to compliance with the procedures for surrender of such Shares as set forth in Section 2.2.

               (c) Cancellation of Treasury Stock and Parent-Owned Stock. All Shares that are held in the treasury of the Company or owned of record by any Company Subsidiary and all Shares owned of record by Parent, Merger Sub or any of their respective wholly-owned Subsidiaries shall be cancelled immediately prior to the Effective Time and shall cease to exist, with no payment being made with respect thereto.

               (d) Merger Sub Common Stock. Each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one newly and validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation.

               (e) Merger Consideration Adjustment. Notwithstanding anything in this Agreement to the contrary, if, from the date of this Agreement until the Effective Time, the outstanding shares of Parent Common Stock or Company Common Stock or the securities convertible into or exercisable for shares of Parent Common Stock or Company Common Stock shall have been changed into a different number of shares or a different class by reason of any reclassification, stock split (including a reverse stock split), recapitalization, split-up, combination, exchange of shares, readjustment, or other similar transaction, or a stock dividend or stock distribution thereon shall be declared with a record date within said period, the Merger Consideration and the Exchange Ratio and any other similarly dependent items, as the case may be, shall be appropriately adjusted to provide the holders of Shares the same economic effect as contemplated by this Agreement prior to such event.

               (f) Total Stock Consideration Adjustment. Notwithstanding anything contained herein to the contrary, if the Total Stock Consideration is less than 40% of the aggregate Base Merger Consideration, then the Exchange Ratio shall be increased (with a corresponding reduction in the Cash Consideration) to the extent necessary so that the Total Stock Consideration is equal to 40% of the aggregate Base Merger Consideration (the “Adjustment”). The Adjustment made pursuant to this Section 2.1(f) shall be made as follows: for each 0.0001 increase to the Exchange Ratio, there will be a corresponding decrease to the Cash Consideration in the amount of the product of 0.0001 multiplied by the Parent Signing Share Price.

          2.2 Payment for Securities; Surrender of Certificates.

               (a) Exchange Agent. Prior to the Effective Time, Parent shall deposit with a nationally recognized financial institution designated by Parent and reasonably acceptable to the Company (the “Exchange Agent”), for the benefit of the holders of Shares, for exchange in accordance with this Article 2, certificates representing the full number of shares of Parent Common Stock issuable pursuant to Section 2.1 in exchange for outstanding shares of Company Common Stock. Prior to the Effective

Time, Parent shall provide or shall cause to be provided to the Exchange Agent in immediately available funds all of the cash necessary to pay the cash portion of the Merger Consideration, and shall, after the Effective Time on the appropriate payment date, if applicable, provide or cause to be provided to the Exchange Agent any dividends or other distributions payable on such shares of Parent Common Stock pursuant to Section 2.2(c) (such shares of Parent Common Stock and cash provided to the Exchange Agent, together with any dividends or other distributions with respect thereto, being hereinafter referred to as the “Exchange Fund”). For the purposes of such deposit, Parent shall assume that there will not be any fractional shares of Parent Common Stock. Parent shall make available to the Exchange Agent, for addition to the Exchange Fund, from time to time as needed, cash sufficient to pay cash in lieu of fractional shares in accordance with Section 2.2(e). The cash component of the Exchange Fund shall be invested by the Exchange Agent, as directed by Parent, in short-term obligations of the United States of America with maturities of no more than 30 days, pending payment thereof by the Exchange Agent to the holders of Shares pursuant to this Article 2. The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Parent Common Stock and cash contemplated to be issued pursuant to Section 2.1 out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose.

               (b) Procedures for Surrender. As promptly as practicable after the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record of a Certificate or non-certificated Shares represented by book-entry (“Book-Entry Shares”), in each case whose Shares were converted into the right to receive the Merger Consideration at the Effective Time pursuant to this Agreement: (i) a letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent, and shall otherwise be in such form and have such other provisions as Parent may reasonably specify, and (ii) instructions for use in effecting the surrender of the Certificates or Book-Entry Shares in exchange for payment of the Merger Consideration issuable and payable in respect thereof, and any dividends or other distributions to which such holders are entitled pursuant to Section 2.2(c). Upon surrender of Certificates for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent, and upon delivery of a letter of transmittal, duly executed and in proper form, with respect to such Certificates or Book-Entry Shares, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificates or Book-Entry Shares shall be entitled to receive in exchange therefor the amount of cash and the number of whole shares of Parent Common Stock (which shall be in non-certificated book-entry form unless a physical certificate is requested) into which each Share formerly represented by such Certificates and each Book-Entry Share was converted pursuant to Section 2.1(a) and cash in lieu of fractional shares of Parent Common Stock as set forth in Section 2.2(e), including any dividends or other distributions to which such holders are entitled pursuant to Section 2.2(c) and the Certificates so surrendered shall forthwith be cancelled. Until such time as the Merger Consideration is issued to or at the direction of the holder of a surrendered Certificate or Book-Entry Shares, such Parent Common Stock shall not be voted on any matter. In the event of a transfer of ownership of Company Common Stock that is not registered in the transfer records of the Company, payment may be made and Merger Consideration may be issued to a Person other than the Person

in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer and other similar Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate so surrendered or shall establish to the satisfaction of Parent that such Taxes either have been paid or are not required to be paid. Payment of the Merger Consideration with respect to Book-Entry Shares shall only be made to the Person in whose name such Book-Entry Shares are registered. Subject to the last sentence of Section 2.2(c), until surrendered as contemplated by this Section 2.2, each Certificate and each Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration into which the Shares theretofore represented by such Certificate or Book-Entry Share having been converted pursuant to Section 2.1(a). No interest shall be paid or accrue on any cash payable upon surrender of any Certificate or Book-Entry Share.

               (c) Dividends. No dividends or other distributions with respect to shares of Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any Certificate formerly representing Company Common Stock or any Book-Entry Share with respect to the shares of Parent Common Stock issuable upon surrender thereof, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.2(e) until the surrender of such Certificate or Book-Entry Share in accordance with this Article 2. Subject to applicable Law, following surrender of any such Certificate, there shall be paid to the holder of the shares of Parent Common Stock issued in exchange therefor, without interest, (i) promptly after the time of such surrender, the amount of any cash payable in lieu of a fractional share of Parent Common Stock to which such holder is entitled pursuant to Section 2.2(e) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such whole shares of Parent Common Stock.

               (d) Transfer Books; No Further Ownership Rights in Shares. As of the close of business on the date of the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of Shares on the records of the Company. The Merger Consideration issued (and paid) in accordance with the terms of this Article 2 upon conversion of any Shares shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to such Shares (other than the right to receive dividends or other distributions, if any, in accordance with Section 2.2(c)). From and after the Effective Time, the holders of Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided for herein or by applicable Law. If, after the Effective Time, Certificates are presented to the Surviving Company or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Agreement.

               (e) Fractional Shares. No certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the conversion of Shares pursuant to Section 2.1, and such fractional share interests shall not entitle the owner thereof to vote or to any rights of a holder of Parent Common Stock. For purposes of this Section 2.2(e), all fractional shares to which a single record holder would be entitled shall be aggregated and calculations shall be rounded to three decimal places. In lieu of any such fractional shares, each holder of Shares who would otherwise be entitled to such fractional shares shall be entitled to an amount in cash, without interest, rounded down to the nearest cent, equal to the product of (A) the amount of the fractional share interest in a share of Parent Common Stock to which such holder is entitled under Section 2.1(a) (or would be entitled but for this Section 2.2(e)) and (B) an amount equal to the average of the closing sale prices of the Parent Common Stock on the NYSE as reported in the Wall Street Journal for each of the twenty consecutive trading days ending with the fifth complete trading day prior to the Closing Date (not counting the Closing Date). As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Shares in lieu of any fractional share interests in Parent Common Stock, the Exchange Agent shall make available such amounts, without interest, to the holders of Shares entitled to receive such cash.

               (f) Termination of Fund; Abandoned Property; No Liability. At any time following nine months after the Effective Time, the Surviving Company shall be entitled to require the Exchange Agent to deliver to it any portion of the Exchange Fund (including any interest received with respect thereto) not disbursed to holders of Shares, and thereafter such holders shall be entitled to look only to the Surviving Company (subject to abandoned property, escheat or other similar Laws) as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Shares and compliance with the procedures set forth in Section 2.2(b), and any dividends or distributions with respect to Parent Common Stock as contemplated by Section 2.2(c), in each case, without interest. Notwithstanding the foregoing, neither the Surviving Company nor the Exchange Agent shall be liable to any holder of a Share for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

               (g) Withholding Rights. Parent, Merger Sub, the Surviving Corporation, the Surviving Company and the Exchange Agent, as the case may be, shall be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to any holder of Shares, Company Options, Restricted Stock or RSUs, as applicable, such amounts that Parent, Merger Sub, the Surviving Corporation, the Surviving Company or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code or any other provision of applicable Law. To the extent that amounts are so withheld by Parent, Merger Sub, the Surviving Corporation, the Surviving Company or the Exchange Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Shares, Company Options, Restricted Stock, or RSUs, as applicable, in respect of which such deduction and withholding was made by Parent, Merger Sub, the Surviving Corporation, the Surviving Company or the Exchange Agent.

               (h) Lost, Stolen or Destroyed Certificates. In the event that any Certificate shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration and any unpaid dividends or other distributions payable or deliverable in respect thereof pursuant to this Agreement; provided, however, that Parent may, in its reasonable discretion and as a condition precedent to the payment of such Merger Consideration, require the owner of such lost, stolen or destroyed Certificate to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent, Merger Sub, the Surviving Corporation, the Surviving Company or the Exchange Agent with respect to the Certificate alleged to have been lost, stolen or destroyed.

          2.3 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, Shares outstanding immediately prior to the Effective Time and held by a holder who is entitled to demand and has properly demanded appraisal for such Shares in accordance with, and who complies with, Sections 5/11.65 and 5/11.70 of the IBCA (such Shares, “Dissenting Shares”) shall not be converted into the right to receive the Merger Consideration as provided in Section 2.1(a), and shall instead represent the right to receive payment of the consideration due to the holder of Dissenting Shares, to the extent available, in accordance with Section 5/11.70 of the IBCA. Upon consummation of the Merger, the Dissenting Shares shall cease to be issued and outstanding and the holders thereof shall be entitled to receive such consideration as will be determined under Section 5/11.70 of the IBCA. If any such holder fails to perfect or otherwise waives, withdraws or loses his right to appraisal under Section 5/11.65 of the IBCA or other applicable Law, then such Dissenting Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for, the right to receive the Merger Consideration as provided in Section 2.1(a) and any unpaid dividends or other distributions payable or deliverable in respect thereof pursuant to Section 2.2(c), in each case without interest. The Company shall serve prompt notice to Parent of any demands received by the Company for appraisal of any Shares, and Parent shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, except with the prior written consent of Parent, make any payment with respect to, or settle, offer to settle or compromise, any such demands, or agree to do any of the foregoing.

          2.4 Treatment of Company Options, Restricted Stock, Restricted Stock Units, Stock Plans.

     (xx) enter into any Contract or commit to do or authorize any of the foregoing.

          Parent will, promptly following the date hereof, designate two individuals from either of whom the Company may seek approval to undertake any actions not permitted to be taken under this Section 5.1(a), and will ensure that such persons will respond, on behalf of Parent, to the Company’s requests as expeditiously as reasonably practicable.

               (a) As promptly as reasonably practicable following the date of this Agreement, Parent and the Company shall prepare and file with the SEC the Joint Proxy Statement in preliminary form and Parent shall file with the SEC the Form S-4, in which the Joint Proxy Statement will be included as a prospectus. Subject to Section 5.4, the Joint Proxy Statement shall include the Company Board Recommendation and the Parent Board Recommendation. Each of Parent and the Company shall cooperate in the preparation and filing of the Form S-4 and Joint Proxy Statement and shall provide the other with a reasonable opportunity to review and comment on such documents prior to

their filing with the SEC. Each of Parent and the Company shall use their best efforts to have the Form S-4 declared effective under the Securities Act as promptly as reasonably practicable after such filing and to keep the Form S-4 effective as long as necessary to consummate the Merger and the Subsequent Merger. The Company shall use its reasonable best efforts to cause the Joint Proxy Statement to be mailed to the Company’s shareholders, and Parent shall use its reasonable best efforts to cause the Joint Proxy Statement to be mailed to Parent’s shareholders, in each case, as promptly as practicable after the Form S-4 is declared effective under the Securities Act. Each of Parent and the Company shall use commercially reasonable efforts to cause to be delivered to the other a “comfort letter” of its independent auditors, dated the date that is two (2) Business Days prior to the date on which the Form S-4 becomes effective. No filing of, or amendment or supplement to, the Form S-4 or the Joint Proxy Statement will be made by Parent or the Company, as applicable, without the other’s prior written consent (which shall not be unreasonably withheld, conditioned or delayed) and without providing the other the reasonable opportunity to review and comment thereon. Parent or the Company, as applicable, will advise the other promptly after it receives oral or written notice of the time when the Form S-4 has become effective or any supplement or amendment has been filed, the issuance of any stop order, the suspension of the qualification of the Parent Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction, or any oral or written request by the SEC for amendment of the Joint Proxy Statement or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information, and will promptly provide the other with copies of any written communication from the SEC or any state securities commission.

               (b) If, at any time prior to the Effective Time, any information relating to Parent or the Company, or any of their respective affiliates, officers or directors, is discovered by Parent or the Company that should be set forth in an amendment or supplement to either the Form S-4 or the Joint Proxy Statement so that either such document would not include any misstatement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein, in light of the circumstances under which they are made, not misleading, the Party that discovers such information shall as promptly as practicable notify the other Party and an appropriate amendment or supplement describing such information shall be filed with the SEC as promptly as practicable after the other Party has had a reasonable opportunity to review and comment thereon, and, to the extent required by applicable Law, disseminated to the respective shareholders of Parent and the Company, as applicable. The Form S-4 and the Joint Proxy Statement will comply as to form and substance in all material respects with the applicable requirements of the Securities Act, the Exchange Act and other applicable Law, including the regulations and requirements of the NYSE.

               (c) In addition to their obligations pursuant to Section 5.2(a) and Section 5.2(b), Parent and the Company shall make all necessary filings with respect to the transactions contemplated hereunder, including the Merger, the Subsequent Merger and the Share Issuance, under the Securities Act, the Exchange Act and applicable Blue Sky Laws, including but not limited to filing of a Form S-8 covering the Parent Common Stock to be held by any Company Benefit Plans following the Effective Time, and each

of Parent and the Company shall furnish all information concerning it and its shareholders as may reasonably be requested by the other Party for purposes of making such filings. Each of Parent and the Company shall make available to each other copies of such filings.

               (d) The Company shall, as promptly as reasonably practicable following effectiveness of the Form S-4, duly call, give notice of, convene and hold the Company Shareholder Meeting for the purpose of seeking the Company Shareholder Approval. Subject to Section 5.4, the Company Board shall recommend that the Company’s shareholders adopt and approve this Agreement and the transactions contemplated hereby, including the Merger (the “Company Board Recommendation”), and the Company shall, unless there has been a Change of Company Board Recommendation, use its reasonable best efforts to solicit from its shareholders proxies in favor of the approval and adoption of this Agreement and the transactions contemplated hereby, including the Merger, and to take all other action necessary or advisable to secure the Company Shareholder Approval.

               (e) Parent shall, as promptly as reasonably practicable following effectiveness of the Form S-4, duly call, give notice of, convene and hold a meeting of its shareholders for the purpose of seeking the Parent Shareholder Approval (as such meeting may be validly adjourned or postponed, the “Parent Shareholder Meeting”). Subject to Section 5.5, the Parent Board shall recommend that Parent’s shareholders approve the Share Issuance and the Charter Amendment (the “Parent Board Recommendation”), and Parent shall, unless there has been a Change of Parent Board Recommendation, use its reasonable best efforts to solicit from its shareholders proxies in favor of the Share Issuance and the Charter Amendment and take all other action necessary or advisable to secure the Parent Shareholder Approval. Other than as expressly permitted by Section 5.5 in connection with a Parent Superior Proposal, the Parent Board shall not, nor publicly propose to, withhold, withdraw, modify or qualify, or propose publicly to withhold, withdraw, amend, modify or qualify the Parent Board Recommendation in a manner adverse to the Company, or make any public statement in connection with such Parent Board Recommendation that is inconsistent with the Parent Board Recommendation (any such actions and/or actions described in clauses (iv) or (v) of Section 5.5(a) being a “Change of Parent Board Recommendation”). Nothing contained in this Section 5.2(e) shall prohibit the Parent Board from making any disclosure to Parent’s shareholders if the Parent Board determines in good faith, after consultation with its outside counsel, that the failure to make such disclosure would reasonably be determined to be inconsistent with applicable Law. Notwithstanding any Change of Parent Board Recommendation, unless this Agreement is terminated in accordance with its terms, the obligations of the Parties hereunder shall continue in full force and effect.

               (f) Each of the Company and Parent will work together in an effort to hold the Company Shareholder Meeting and the Parent Shareholder Meeting, respectively, on the same date as the other Party.

Parent agrees to indemnify and hold the Company and Company Subsidiaries harmless from any and all claims and liabilities, including related costs and expenses, resulting from the action of any Parent Representative or any information provided to such Parent Representatives pursuant to this Section 5.3(a).

               (b) From the date of this Agreement to the Effective Time, Parent shall, and shall cause each Parent Subsidiary and each Parent Representative to: (i) provide to the Company and the Company Representatives reasonable access during normal business hours in such a manner as not to interfere unreasonably with the operation of any business conducted by Parent or any Parent Subsidiary, upon reasonable advance notice to Parent, to the officers, employees, properties, offices and other facilities of Parent and the Parent Subsidiaries and to the books, contracts and records thereof (including Tax Returns) and (ii) furnish promptly such information concerning the business, properties, contracts, assets and liabilities of Parent and Parent Subsidiaries as the Company or the Company Representatives may reasonably request; provided, however, that Parent shall not be required to (or to cause any Parent Subsidiary to) afford such access or furnish such information to the extent that Parent believes that doing so would: (A) result in the loss of attorney-client privilege (provided that Parent shall use its reasonable efforts to allow for such access or disclosure in a manner that does not result in a loss of attorney-client privilege), (B) result in the disclosure of any trade secrets of

               (a) Subject to Section 5.4(b), from and after the date hereof until the Effective Time or, if earlier, the termination of this Agreement in accordance with Article 7, the Company agrees that neither it nor any of the Company Subsidiaries shall, and shall use its reasonable best efforts to cause the Company Representatives not to (and each shall not authorize or give permission to the Company Representatives to), directly or indirectly: (i) initiate, solicit, seek, induce or intentionally encourage or facilitate, any inquiries or the making of any proposal or offer that constitutes or would reasonably be expected to lead to an Acquisition Proposal involving the Company or any Significant Company Subsidiary, or engage in any discussions or negotiations with respect thereto, (ii) except as expressly permitted by this Agreement, enter into, continue or otherwise participate in any discussions or negotiations with any Person (other than Parent and Merger Sub) with respect to an Acquisition Proposal, (iii) furnish any information regarding the Company or any Significant Company Subsidiaries to, or afford access to the properties, books and records of the Company to, any Person (other than Parent and Merger Sub) in connection with or in response to an Acquisition Proposal, (iv) approve, endorse or recommend, or publicly propose to approve, endorse or recommend, any Acquisition Proposal involving the Company, (v) withhold, withdraw, qualify, amend or modify, in a manner adverse to Parent, or publicly propose to withdraw, qualify, amend or modify, in a manner adverse to Parent, the Company Board Recommendation, (vi) enter into any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement constituting, or relating to, any Acquisition Proposal or requiring it to abandon, terminate or fail to consummate the Merger or any other transactions contemplated by this Agreement, or (vii) resolve or agree to do any of the foregoing (any action set forth in the

The Company shall, and shall cause the Company Subsidiaries and the Company Representatives to, immediately cease and cause to be terminated any and all activities, discussions or negotiations with any Persons conducted prior to the date hereof by the Company, the Company Subsidiaries or any of the Company Representatives with respect to any Acquisition Proposal involving the Company or a Company Subsidiary. Not later than the 45^th day after the date hereof, the Company shall request each Person that has heretofore executed a confidentiality agreement in connection with its consideration of any Acquisition Proposal to return or destroy all confidential information furnished prior to the execution of this Agreement to or for the benefit of such Person by or on behalf of the Company or any Company Subsidiary; provided, that if the Company shall have provided Parent the notice specified in Section 5.4(d)(iii)(A) with respect to an Acquisition Proposal prior to the 45^th day after the date of this Agreement, the Company shall not be required to request that the Person making the Acquisition Proposal return or destroy all such confidential information during the period that the Company is considering such Acquisition Proposal.

The Company agrees that it will promptly inform the Company Representatives of the obligations undertaken in this Section 5.4.

Nothing in this Section 5.4 shall restrict the Company or any Company Subsidiary from making any acquisition that is otherwise permitted by Section 5.1(a)(vii).

               (b) Notwithstanding anything to the contrary contained in Section 5.4(a), if at any time following the date hereof and prior to the Company securing the Company Shareholder Approval (i) the Company has received an unsolicited, bona fide written Acquisition Proposal involving the Company or any Significant Company Subsidiary that did not result from a breach of this Section 5.4 and (ii) the Company Board determines in good faith, after consultation with its financial advisors and outside counsel, that such Acquisition Proposal constitutes or is reasonably likely to result in a Superior Proposal, then the Company may then take the following actions: (A) furnish information with respect to the Company and the Company Subsidiaries to the Person making such Acquisition Proposal and its representatives and (B) participate in discussions or negotiations with the Person making such Acquisition Proposal and its representatives regarding such Acquisition Proposal; provided, that the Company (x) will not, and will not allow the Company Subsidiaries and the Company Representatives to, disclose any information to such Person without first entering into an Acceptable Confidentiality Agreement and (y) will as promptly as practicable provide to Parent any material information concerning the Company or the Company Subsidiaries provided or made available to such other Person (or its representatives) which was not previously provided or made available to Parent.

               (c) In addition to the obligations of the Company set forth in Sections 5.4(a), (b) and (d) hereof, as promptly as reasonably practicable (and in any event within 24 hours) after receipt of any Acquisition Proposal or any request for

nonpublic information or any request or inquiry relating in any way to, or that would reasonably be expected to lead to, any Acquisition Proposal, the Company shall provide Parent with notice of the material terms and conditions of such Acquisition Proposal, request or inquiry, and the identity of the Person making any such Acquisition Proposal, request or inquiry and a copy of all written materials provided to it in connection with such Acquisition Proposal, request or inquiry. In addition, the Company shall provide Parent as promptly as practicable (and in any event within one Business Day) with all information as is reasonably necessary to keep Parent reasonably informed of all material developments and any changes to the economic or other material terms of, any such Acquisition Proposal, request or inquiry, and shall provide, as promptly as reasonably practicable, to Parent (i) a copy of all material written materials (including material written materials provided by email or otherwise in electronic format) provided by or to the Company, any of the Company Subsidiaries or the Company Representatives making or materially amending, modifying or supplementing such Acquisition Proposal, request or inquiry, or (ii) if oral, a reasonably detailed summary of the terms of such Acquisition Proposal, request or inquiry and any material amendment, modification or supplementation thereof.

               (d) Notwithstanding anything to the contrary contained in Section 5.4(a), the Company Board may, in response to a Superior Proposal, terminate this Agreement pursuant to Section 7.1(f)(ii) and concurrently enter into a definitive agreement with respect to such Superior Proposal, if all of the following conditions are met, as applicable: (i) such Superior Proposal has been made and has not been withdrawn and, taking into account any revised terms offered by Parent, continues to constitute a Superior Proposal; (ii) the Company Shareholder Approval has not theretofore been obtained; (iii) the Company has (A) initially provided to Parent five Business Days’ prior written notice which shall state expressly (1) that it has received an Acquisition Proposal that it has determined or is prepared to determine constitutes a Superior Proposal, (2) the material terms and conditions of the Superior Proposal (including the consideration offered therein and the identity of the Person making the Superior Proposal), and shall have contemporaneously provided a copy of the relevant proposed transaction agreements making such Superior Proposal and other material documents, including the definitive agreement with respect to such Superior Proposal (the “Alternative Acquisition Agreement”) (it being understood and agreed that any amendment to the financial terms or any other material term of such Superior Proposal shall require a notice and a new period of (x) 72 hours, or (y) solely in the event Parent notifies the Company that it has reasonably and in good faith determined that it would be prudent to seek and will seek rating agency review prior to modifying or amending the terms of this Agreement, a total of five Business Days (which, for the avoidance of doubt, is inclusive of, rather than in addition to, the 72 hours set forth in clause (x)) and (3) that it intends to terminate this Agreement, and (B) prior to terminating this Agreement, to the extent requested by Parent, engaged in good faith negotiations with Parent to amend this Agreement in such a manner that the Alternative Acquisition Agreement ceases to constitute a Superior Proposal; (iv) the Company shall not have breached any of the provisions set forth in this Section 5.4 in any material respect; and (v) in advance of or concurrently with such termination, the Company pays the Company Termination Fee.

               (e) Notwithstanding anything to the contrary contained in Section 5.4(a), the Company Board may make a Change of Company Board Recommendation (other than in connection with the Company terminating this Agreement to enter into an Alternative Acquisition Agreement pursuant to Section 5.4(d)) if it determines in good faith after consultation with its outside counsel that the failure to effect a Change of Company Board Recommendation would constitute a breach of its fiduciary duties to the shareholders of the Company under applicable Law; provided, that (i) the Company has provided Parent five Business Days’ prior written notice advising Parent that it intends to effect a Change of Company Board Recommendation and specifying, in reasonable detail, the reasons for the Change of Company Board Recommendation and (ii) during such five Business Day period, if requested by Parent, the Company engages in good faith negotiations with Parent to amend the terms of this Agreement in a manner that obviates the need for the Change of Company Board Recommendation.

               (f) Nothing contained in this Section 5.4 shall prohibit the Company Board from (i) disclosing to the shareholders of the Company a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act; or (ii) making any disclosure to the shareholders of the Company if the Company Board determines in good faith, after consultation with outside counsel, that the failure to make such disclosure would constitute a breach of its fiduciary duties to the shareholders of the Company under applicable Law (for the avoidance of doubt, it being agreed that the issuance by the Company or the Company Board of a “stop, look and listen” statement pending disclosure of its position, as contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act, shall not constitute a Change of Company Board Recommendation).

          5.5 Parent No Solicitation of Transactions; Change of Parent Board Recommendation.

               (a) Subject to Section 5.5(b), from and after the date hereof until the Effective Time or, if earlier, the termination of this Agreement in accordance with Article 7, Parent agrees that neither it nor any of the Parent Subsidiaries shall, and shall use its reasonable best efforts to cause the Parent Representatives not to (and each shall not authorize or give permission to the Parent Representatives to), directly or indirectly: (i) initiate, solicit, seek, induce or intentionally encourage or facilitate, any inquiries or the making of any proposal or offer that constitutes or would reasonably be expected to lead to an Acquisition Proposal involving Parent or any Significant Parent Subsidiary, or engage in any discussions or negotiations with respect thereto, (ii) except as expressly permitted by this Agreement, enter into, continue or otherwise participate in any discussions or negotiations with any Person (other than the Company) with respect to an Acquisition Proposal, (iii) furnish any information regarding Parent or any Significant Parent Subsidiaries to, or afford access to the properties, books and records of Parent to, any Person (other than the Company) in connection with or in response to an Acquisition Proposal, (iv) approve, endorse or recommend, or publicly propose to approve, endorse or recommend, any Acquisition Proposal involving Parent, (v) withhold, withdraw, qualify, amend or modify, in a manner adverse to the Company, or publicly propose to

Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in this Section 5.5(a) by Parent or any Significant Parent Subsidiary shall be deemed to be a breach of this Section 5.5(a) by Parent. Parent shall, and shall cause the Parent Subsidiaries and the Parent Representatives to, immediately cease and cause to be terminated any and all activities, discussions or negotiations with any Persons conducted prior to the date hereof by Parent, the Parent Subsidiaries or any of the Parent Representatives with respect to any Acquisition Proposal involving Parent or a Parent Subsidiary.

Parent agrees that it will promptly inform the Parent Representatives of the obligations undertaken in this Section 5.5.

Nothing in this Section 5.5 shall restrict Parent or any Parent Subsidiary from making any acquisition that is otherwise permitted by Section 5.1(b)(vi).

               (b) Notwithstanding anything to the contrary contained in Section 5.5(a), if at any time following the date hereof and prior to Parent securing the Parent Shareholder Approval (i) Parent has received an unsolicited, bona fide written Acquisition Proposal involving Parent or any Significant Parent Subsidiary that did not result from a breach of this Section 5.5 and (ii) the Parent Board determines in good faith, after consultation with its financial advisors and outside counsel, that such Acquisition Proposal constitutes or is reasonably likely to result in a Parent Superior Proposal, then Parent may then take the following actions: (A) furnish information with respect to Parent and the Parent Subsidiaries to the Person making such Acquisition Proposal and its representatives and (B) participate in discussions or negotiations with the Person making such Acquisition Proposal and its representatives regarding such Acquisition Proposal; provided, that Parent (x) will not, and will not allow the Parent Subsidiaries and the Parent Representatives to, disclose any information to such Person without first entering into a confidentiality agreement that contains provisions restricting such Person that are no less favorable in the aggregate to Parent than those contained in the Confidentiality Agreement and (y) will as promptly as practicable provide to the Company any material information concerning Parent or the Parent Subsidiaries provided or made available to such other Person (or its representatives) which was not previously provided or made available to the Company.

               (c) In addition to the obligations of Parent set forth in Sections 5.5(a), (b) and (d) hereof, as promptly as reasonably practicable (and in any event within 24 hours) after receipt of any Acquisition Proposal or any request for nonpublic information or any request or inquiry relating in any way to, or that would reasonably be expected to lead to, any Acquisition Proposal, Parent shall provide the Company with notice of the material terms and conditions of such Acquisition Proposal, request or

inquiry, and the identity of the Person making any such Acquisition Proposal, request or inquiry and a copy of all written materials provided to it in connection with such Acquisition Proposal, request or inquiry. In addition, Parent shall provide the Company as promptly as practicable (and in any event within one Business Day) with all information as is reasonably necessary to keep the Company reasonably informed of all material developments and any changes to the economic or other material terms of, any such Acquisition Proposal, request or inquiry, and shall provide, as promptly as reasonably practicable, to the Company (i) a copy of all material written materials (including material written materials provided by email or otherwise in electronic format) provided by or to Parent, any of the Parent Subsidiaries or the Parent Representatives making or materially amending, modifying or supplementing such Acquisition Proposal, request or inquiry, or (ii) if oral, a reasonably detailed summary of the terms of such Acquisition Proposal, request or inquiry, and any material amendment, modification or supplementation thereof.

               (d) Notwithstanding anything to the contrary contained in Section 5.5(a), the Parent Board may, in response to a Parent Superior Proposal, terminate this Agreement pursuant to Section 7.1(e)(ii) and concurrently enter into a definitive agreement with respect to such Parent Superior Proposal, if all of the following conditions are met, as applicable: (i) such Parent Superior Proposal (A) has been made and has not been withdrawn, and (B) continues to constitute a Parent Superior Proposal; (ii) either (A) such Parent Superior Proposal requires or conditions the consummation of the Acquisition Proposal on Parent’s termination of this Agreement or (B) after ten Business Days’ prior written notice, during which period Parent shall have engaged in good faith negotiations with the Company and the other Person to enable the consummation of both the transactions contemplated by this Agreement and such Acquisition Proposal, (1) the Company and Parent have not reached agreement and amended this Agreement to permit Parent to pursue such Parent Superior Proposal in accordance with its terms, and (2) the Company has not waived those breaches of this Agreement that would result if Parent entered into a Parent Alternative Acquisition Agreement or consummated a Parent Superior Proposal, in order to permit Parent to pursue such Parent Superior Proposal in accordance with its terms, without adverse consequence to Parent, Merger Sub or Merger LLC hereunder; provided that such ten Business Day period shall (x) only be imposed one time with respect to any Person that makes such an Acquisition Proposal, and (y) run concurrently with any other applicable notice period under this Section 5.5(d); (iii) the Parent Shareholder Approval has not theretofore been obtained; (iv) Parent has (A) initially provided to the Company five Business Days’ prior written notice which shall state expressly (1) that it has received an Acquisition Proposal that it has determined or is prepared to determine constitutes a Parent Superior Proposal, (2) the material terms and conditions of the Parent Superior Proposal (including the consideration offered therein and the identity of the Person making the Parent Superior Proposal), and shall have contemporaneously provided a copy of the relevant proposed transaction agreements making such Parent Superior Proposal and other material documents, including the definitive agreement with respect to such Parent Superior Proposal (the “Parent Alternative Acquisition Agreement”) (it being understood and agreed that any amendment to the financial terms or any other material term of such Parent Superior Proposal shall require a notice and a new period, which

shall be 72 hours instead of five Business Days) and (3) that it intends to terminate this Agreement, and (B) prior to terminating this Agreement, to the extent requested by the Company, engaged in good faith negotiations with the Company to amend this Agreement in such a manner that the Parent Alternative Acquisition Agreement ceases to constitute a Parent Superior Proposal or enables the consummation of both the transactions contemplated by this Agreement and such Acquisition Proposal; (v) the Parent Board has determined in good faith, after consultation with its legal counsel, that, in light of such Parent Superior Proposal and taking into account any revised terms offered by the Company, the failure to terminate this Agreement and enter into the Parent Alternative Acquisition Agreement would reasonably be expected to constitute a breach of its fiduciary duties under applicable Law; (vi) Parent shall not have breached any of the provisions set forth in this Section 5.5 in any material respect; and (vii) in advance of or concurrently with such termination, Parent pays the Parent Termination Fee.

               (e) Nothing contained in this Section 5.5 shall prohibit the Parent Board from (i) disclosing to the shareholders of Parent a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act; or (ii) making any disclosure to the shareholders of Parent if the Parent Board determines in good faith, after consultation with outside counsel, that the failure to make such disclosure would constitute a breach of its fiduciary duties to the shareholders of Parent under applicable Law (for the avoidance of doubt, it being agreed that the issuance by Parent or the Parent Board of a “stop, look and listen” statement pending disclosure of its position, as contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act, shall not constitute a Change of Parent Board Recommendation).

          5.6 Appropriate Action; Consents; Filings.

               (a) Upon the terms and subject to the conditions set forth in this Agreement, the Company and Parent shall cooperate and use their reasonable best efforts (subject to, and in accordance with, applicable Law) to take, or cause to be taken, all appropriate action and do, or cause to be done, and to assist the other Party in doing all things necessary, proper or advisable on its part under applicable Law or otherwise to (i) consummate and make effective, the Merger, the Subsequent Merger and the other transactions contemplated by this Agreement as promptly as practicable, (ii) obtain from any Governmental Entities any consents, licenses, permits, waivers, approvals, authorizations or orders required to be obtained by Parent or the Company or any of their respective Subsidiaries, or to avoid any action or proceeding by any Governmental Entity (including, those in connection with the HSR Act, the NGA, PUHCA 2005 and the Illinois Statutes), in connection with the authorization, execution and delivery of this Agreement and the consummation of the transactions contemplated hereby, (iii) cause the satisfaction of all conditions set forth in Article 6, (iv) resolve all lawsuits or other legal, regulatory or other governmental proceedings to which it is a party challenging or affecting this Agreement or the consummation of the transactions contemplated by this Agreement, in each case until the issuance of a final, non-appealable order, (v) seek to have lifted or rescinded any injunction or restraining order which may adversely affect the ability of the Parties to consummate the transactions contemplated hereby, in each

case until the issuance of a final, non-appealable order, and (vi) as promptly as practicable, and in any event within 60 days after the date hereof, make or cause to be made all necessary applications and filings, and thereafter make any other required submissions, and pay any fees due in connection therewith, with respect to this Agreement and the Merger and Subsequent Merger required under the HSR Act and the Illinois Statutes and any other applicable Law; provided, that the Company and Parent shall cooperate with each other in connection with determining whether any action by or in respect of, or filing with, any Governmental Entity is required in connection with the consummation of the Merger and the Subsequent Merger and seeking any such actions, consents, approvals or waivers or making any such filings. The Company and Parent shall furnish to each other all information required for any application or other filing under the rules and regulations of any applicable Law in connection with the transactions contemplated by this Agreement. No Party to this Agreement shall consent to any voluntary delay of the Closing at the behest of any Governmental Entity without the consent of the other Parties to this Agreement, which consent shall not be unreasonably withheld, delayed or conditioned. Parent shall not, except as may be consented to in writing by the Company, directly or indirectly through one or more of its affiliates, seek to acquire or acquire any regulated gas distribution utility (x) in the State of Illinois or (y) in any other jurisdiction, if such acquisition would present more than a de minimis risk of materially delaying or materially increasing the risk of any of the Parties hereto not obtaining the approval of the ICC with respect to the transactions contemplated by this Agreement. The Company and Parent will consult with each other prior to agreeing to any merger requirements sought by any Governmental Entity, to the extent permitted under applicable Law. Nothing in this Section 5.6 shall obligate Parent or the Company or any of their respective Subsidiaries to take any action that is not conditioned on the Closing.

               (b) The Company and Parent shall give (or shall cause their respective Subsidiaries to give) any notices to third parties, and use, and cause their respective Subsidiaries to use, their commercially reasonable efforts to obtain any third party consents (i) necessary, proper or advisable to consummate the Merger, the Subsequent Merger and the other transactions contemplated by this Agreement or (ii) disclosed in the Company Disclosure Letter or the Parent Disclosure Letter, as applicable; provided, however that the Company and Parent shall coordinate and cooperate in determining whether any actions, consents, approvals or waivers are required to be obtained from parties to any Company Real Property Leases and Company Scheduled Contracts in connection with the consummation of the Merger or the Subsequent Merger and in seeking any such actions, consents, approvals or waivers. In the event that either Party shall fail to obtain any third party consent described in this Section 5.6(b), such Party shall use its commercially reasonable efforts, and shall take any such actions reasonably requested by the other Party hereto, to minimize any adverse effect upon the Company and Parent, their respective Subsidiaries, and their respective businesses resulting, or which could reasonably be expected to result, after the Effective Time, as applicable, from the failure to obtain such consent.

               (c) Without limiting the generality of anything contained in this Section 5.6, each Party hereto shall: (i) give the other Parties prompt notice of the

making or commencement of any request, inquiry, investigation, action or legal proceeding by or before any Governmental Entity with respect to the Merger, the Subsequent Merger or any of the other transactions contemplated by this Agreement; (ii) keep the other Parties informed as to the status of any such request, inquiry, investigation, action or legal proceeding; and (iii) promptly inform the other Parties of any communication to or from the Federal Trade Commission, the Department of Justice, FERC, the ICC or any other Governmental Entity regarding the Merger or the Subsequent Merger. Each Party hereto will consult and cooperate with the other Parties and will consider in good faith the views of the other Parties in connection with any filing, analysis, appearance, presentation, memorandum, brief, argument, opinion or proposal made or submitted in connection with the Merger, the Subsequent Merger or any of the other transactions contemplated by this Agreement. In addition, except as may be prohibited by any Governmental Entity or by any Law, in connection with any such request, inquiry, investigation, action or legal proceeding, each Party hereto will permit authorized representatives of the other Parties to be present at each meeting or conference relating to such request, inquiry, investigation, action or legal proceeding and to have access to and be consulted in connection with any document, opinion or proposal made or submitted to any Governmental Entity in connection with such request, inquiry, investigation, action or legal proceeding.

               (d) Nothing contained in this Agreement shall give Parent or Merger Sub, directly or indirectly, the right to control or direct the operations of the Company prior to the Effective Time. Prior to the Effective Time, the Company shall exercise, consistent with the terms and conditions of this Agreement, complete unilateral control and supervision over its business operations.

          5.7 Certain Notices. From and after the date of this Agreement until the Effective Time, each Party hereto shall promptly notify the other Party hereto of (a) the occurrence or non-occurrence of any event that would be likely to cause any condition to the obligations of any Party to effect the Merger, the Subsequent Merger or any other transaction contemplated by this Agreement not to be satisfied or (b) the failure of the Company, Parent, Merger Sub or Merger LLC, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it pursuant to this Agreement which would reasonably be expected to result in any condition to the obligations of any Party to effect the Merger, the Subsequent Merger or any other transaction contemplated by this Agreement not to be satisfied; provided, however, that the delivery of any notice pursuant to this Section 5.7 shall not cure any breach of any representation, warranty, covenant or agreement contained in this Agreement or otherwise limit or affect the remedies available hereunder to the Party receiving such notice.

          5.8 Public Announcements. Each of the Company, Parent, Merger Sub and Merger LLC agrees that no public release or announcement concerning the transactions contemplated hereby shall be issued by any Party without the prior written consent of the Company and Parent (which consent shall not be unreasonably withheld, conditioned or delayed), except as such release or announcement may be required by applicable Law or the rules or regulations of any applicable United States securities

exchange or Governmental Entity to which the relevant Party is subject, in which case the Party required to make the release or announcement shall use its commercially reasonable efforts to allow each other Party reasonable time to comment on such release or announcement in advance of such issuance. The Company, Parent, Merger Sub and Merger LLC agree that the press release announcing the execution and delivery of this Agreement shall be a joint release of, and shall not be issued prior to the approval of each of, the Company and Parent.

          5.9 Employee Benefit Matters.

               (a) For a period of one year following the Effective Time (the “Benefit Protection Period”), Parent shall either (i) assume and maintain, or cause the Parent Subsidiaries, including the Surviving Company, to assume and maintain, for the benefit of the employees of the Company and Company Subsidiaries immediately prior to the Effective Time (the “Company Employees”), the Company Benefit Plans (other than the Company Equity Plans and the ESPP) at the benefit levels in effect on the date of this Agreement and provide or cause the Parent Subsidiaries, including the Surviving Company, to provide compensation and benefits to each Company Employee under the Company Benefit Plans or other employee benefit plans or compensation arrangements of Parent or any of the Parent Subsidiaries that have a value sufficient to replace the value of the compensation and benefits provided to such Company Employee under the Company Benefit Plans immediately prior to the Effective Time taking into account the value of equity based compensation, or (ii) provide or cause the Parent Subsidiaries, including the Surviving Company, to provide compensation and benefits to each Company Employee that, taken as a whole (including equity based compensation), is not less favorable in the aggregate than the compensation and benefits provided to such Company Employee immediately prior to the Effective Time.

               (b) Without limiting the generality of Section 5.9(a), from and after the Effective Time, Parent shall, or shall cause the Parent Subsidiaries, including the Surviving Company, to, assume, honor and continue without amendment during the Benefit Protection Period or, if sooner, until all obligations thereunder have been satisfied, all of the Company’s employment, severance, retention and termination plans, policies, programs, agreements and arrangements (including any change in control or severance agreement between the Company and any Company Employee), in each case, as in effect at the Effective Time, including with respect to any payments, benefits or rights arising as a result of the transactions contemplated by this Agreement (either alone or in combination with any other event), without any amendment or modification, other than any amendment or modification required to comply with applicable Law or as consented to by the parties thereto.

               (c) Without limiting the generality of Section 5.9(a), the Surviving Company and its Subsidiaries shall be permitted to make payments to Company Employees pursuant to annual cash incentive plans with respect to the annual performance period in which the Effective Time occurs upon the terms and conditions consistent with the terms of the annual cash incentive plans as in effect on the date hereof, or such future plans as may be established by the compensation committee of the

Company Board, consistent with the parameters set forth on Section 5.9(c) of the Company Disclosure Letter, for annual performance periods commencing after the date hereof, which such future plans shall be consistent with the Company’s and the Company Subsidiaries’ business plans and past practice.

               (d) With respect to any “employee benefit plan,” as defined in Section 3(3) of ERISA, maintained by Parent or any of the Parent Subsidiaries, including the Surviving Company (including any vacation, paid time-off and severance plans), for all purposes, including determining eligibility to participate, level of benefits, vesting, benefit accruals and early retirement subsidies, each Company Employee’s service with the Company or any Company Subsidiary (as well as service with any predecessor employer of the Company or any Company Subsidiary, to the extent service with the predecessor employer is recognized by the Company or such Company Subsidiary) shall be treated as service with Parent or any of the Parent Subsidiaries, including the Surviving Company; provided, however, that such service need not be recognized to the extent that such recognition would result in any duplication of benefits.

               (e) Parent shall, or shall cause the Parent Subsidiaries, including the Surviving Company, to waive, or cause to be waived, any pre-existing condition limitations, exclusions, actively at work requirements and waiting periods under any welfare benefit plan maintained by Parent or any of the Parent Subsidiaries in which Company Employees (and their eligible dependents) will be eligible to participate from and after the Effective Time, except to the extent that such pre-existing condition limitations, exclusions, actively-at-work requirements and waiting periods would not have been satisfied or waived under the comparable Company Benefit Plan immediately prior to the Effective Time. Parent shall, or shall cause the Parent Subsidiaries, including the Surviving Company, to recognize, or cause to be recognized, the dollar amount of all co-payments, deductibles and similar expenses incurred by each Company Employee (and his or her eligible dependents) during the calendar year in which the Effective Time occurs for purposes of satisfying such year’s deductible and co-payment limitations under the relevant welfare benefit plans in which such Company Employee (and dependents) will be eligible to participate from and after the Effective Time.

          5.10 Takeover Laws. If any “control share acquisition”, “fair price”, “business combination” or other state takeover statute or similar Law becomes or is deemed to be applicable to the Merger, including the acquisition of Shares pursuant thereto, the Subsequent Merger or any other transaction contemplated by this Agreement, then the Company Board or the Parent Board, as applicable, shall take all action reasonably available to it (i) to render such Law inapplicable to the foregoing and (ii) to ensure that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms required by, or provided for, in this Agreement and otherwise to minimize the effect of such Law on the Merger, the Subsequent Merger or any other transaction contemplated hereby .

          5.11 Indemnification of Directors and Officers.

               (a) For a period beginning at the Effective Time and ending on the sixth anniversary of the Effective Time, Parent and the Surviving Company shall indemnify and hold harmless all former and current directors, officers and employees of the Company or any Company Subsidiary to the same extent such Persons are indemnified as of the date of this Agreement by the Company pursuant to applicable Law, the Company Charter, the Company Bylaws, the articles of incorporation and bylaws, or equivalent organizational or governing documents, of any Company Subsidiary, and indemnification agreements, if any, in existence on the date of this Agreement with any directors, officers and employees of the Company or any Company Subsidiary, arising out of acts or omissions in their capacity as directors, officers or employees of the Company or any Company Subsidiary occurring at or prior to the Effective Time; provided, however, that Parent agrees, and Parent will cause the Surviving Company to, indemnify and hold harmless such persons to the fullest extent permitted by Law for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby. Parent and the Surviving Company shall advance expenses (including reasonable legal fees and expenses) incurred in the defense of any claim, action, suit, proceeding or investigation with respect to the matters subject to indemnification pursuant to this Section 5.11 in accordance with the procedures and limitations set forth in the Company Charter, the Company Bylaws, the articles of incorporation and bylaws, or equivalent organizational documents, of any Company Subsidiary, and indemnification agreements, if any, in existence on the date of this Agreement; provided, however, that the director, officer or employee to whom expenses are advanced undertakes to repay such advanced expenses to Parent and the Surviving Company if it is ultimately determined that such director, officer or employee is not entitled to indemnification pursuant to this Section 5.11(a). Notwithstanding anything herein to the contrary, if any claim, action, suit, proceeding or investigation (whether arising before, at or after the Effective Time) is made against such persons with respect to matters subject to indemnification hereunder on or prior to the sixth anniversary of the Effective Time, the provisions of this Section 5.11(a) shall continue in effect until the final disposition of such claim, action, suit, proceeding or investigation.

               (b) For not less than six years from and after the Effective Time, the governing documents of the Surviving Company shall contain provisions no less favorable with respect to exculpation, indemnification and advancement of expenses of directors, officers and employees of the Company for periods at or prior to the Effective Time than are currently set forth in the Company Charter and the Company Bylaws. The indemnification agreements, if any, in existence on the date of this Agreement with any of the directors, officers or employees of the Company or any Company Subsidiary shall be assumed by the Surviving Company, without any further action, and shall continue in full force and effect in accordance with their terms following the Effective Time.

               (c) For the benefit of the Company’s directors and officers, as of the date of this Agreement and as of the Effective Time, the Company shall be

permitted, prior to the Effective Time, to obtain and fully pay the premium for an insurance and indemnification policy that provides coverage for a period of six years from and after the Effective Time for events occurring prior to the Effective Time (the “D&O Insurance”) that is substantially equivalent to and in any event not less favorable in the aggregate than the Company’s existing policy (true and complete copies which have been previously provided to Parent) or, if substantially equivalent insurance coverage is unavailable, the best available coverage; provided, however, that the annual premium payable by the Company for any such policy shall not exceed 250% of the last annual premium paid by the Company for comparable director and officer insurance coverage prior to the date of this Agreement but in such case may purchase as much coverage as is available for such amount. If the Company is unable to purchase such D&O Insurance prior to the Effective Time, the Surviving Company shall, and Parent shall cause the Surviving Company to, as of the Effective Time, obtain and fully pay the premium for D&O Insurance that is substantially equivalent to and in any event not less favorable in the aggregate than the Company’s existing policy (true and complete copies which have been previously provided to Parent) or, if substantially equivalent insurance coverage is unavailable, the best available coverage; provided, however, that the Surviving Company shall not be required to pay an annual premium for the D&O Insurance in excess of 250% of the last annual premium paid by the Company for comparable director and officer insurance coverage prior to the date of this Agreement, but in such case shall purchase as much coverage as is available for such amount. The Surviving Company shall maintain such policies in full force and effect, and continue to honor the obligations thereunder for a period of not less than six years from and after the Effective Time.

               (d) In the event Parent or the Surviving Company (i) consolidates with or merges into any other Person and shall not be the continuing or surviving company or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then proper provision shall be made so that such continuing or surviving company or entity or transferee of such assets, as the case may be, shall assume the obligations set forth in this Section 5.11.

               (e) The obligations under this Section 5.11 shall not be terminated or modified in such a manner as to adversely affect any former or current directors, officers and employees of the Company to whom this Section 5.11 applies without the consent of such affected Person (it being expressly agreed that the persons to whom this Section 5.11 applies are express third party beneficiaries of this Section 5.11).

               (f) In the event of any breach by the Surviving Company or Parent of this Section 5.11, the Surviving Company or Parent shall pay all reasonable expenses, including attorneys’ fees, that may be incurred by any former or current directors, officers and employees of the Company in enforcing the indemnity and other obligations provided in this Section 5.11 as such fees are incurred upon the written request of such person.

          5.12 Parent Agreements Concerning Merger Sub and Merger LLC. Parent hereby guarantees the due, prompt and faithful payment, performance and

discharge by Merger Sub and Merger LLC of, and the compliance by Merger Sub and Merger LLC with, all of the covenants, agreements, obligations and undertakings of Merger Sub and Merger LLC under this Agreement in accordance with the terms of this Agreement, and covenants and agrees to take all actions necessary or advisable to ensure such payment, performance and discharge by Merger Sub and Merger LLC hereunder. Parent shall, promptly following execution of this Agreement, approve and adopt this Agreement in its capacity as sole shareholder of Merger Sub and as the sole member of Merger LLC and deliver to the Company evidence of its vote or action by written consent approving and adopting this Agreement in accordance with applicable Law and the articles of incorporation and bylaws of Merger Sub and the articles of organization and operating agreement of Merger LLC.

          5.13 Financing.

               (a) Each of Parent and Merger Sub shall use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things reasonably necessary, proper or advisable to consummate and obtain the Financing on the terms and conditions described in the Commitment Letter, including (i) taking actions to enforce its rights under the Commitment Letter and (ii) using its reasonable best efforts to (A) negotiate definitive agreements with respect thereto on the terms and conditions contained therein or on other terms no more adverse to the Company in any material respect, (B) satisfy on a timely basis all conditions applicable to Parent and Merger Sub in such definitive agreements and (C) consummate the Financing at or prior to the Effective Time. Parent will furnish correct and complete copies of all such definitive agreements to the Company promptly upon their execution. Parent and Merger Sub shall keep the Company informed on a reasonably current basis in reasonable detail of the status of its efforts to complete the Financing.

               (b) Each of Parent and Merger Sub shall not agree to any amendment, replacement, supplement or other modification of, or waive any of its rights under or consent to the assignment of, the Commitment Letter or any definitive agreements related to the Financing, in each case, without the Company’s prior written consent, including any such amendment, replacement, supplement or other modification to or assignment or waiver of any provision of the Commitment Letter that amends, supplements or otherwise modifies the conditions precedent to the Financing; provided, however, that (i) Parent may terminate and replace the Commitment Letter with a New Commitment Letter or (ii) Parent may amend the Commitment Letter solely to add lenders, lead arrangers, bookrunners, syndication agents or similar entities who had not executed the Commitment Letter as of the date hereof so long as (x) the addition of such lenders, lead arrangers, bookrunners, syndication agents or similar entities would not reasonably be expected to prevent or materially delay the consummation of the transactions contemplated by this Agreement and (y) the Arranger (as defined in the Commitment Letter) shall remain obligated and committed to fund its financing commitments under the Commitment Letter (as in effect prior to any such amendment) on the terms and conditions of, and subject to the assignment provisions set forth in, the Commitment Letter (as in effect prior to any such amendment). Upon any such amendment, replacement, supplement or modification of the Commitment Letter in

accordance with this Section 5.13(b), the term “Commitment Letter” shall mean the Commitment Letter as so amended, supplemented or modified in accordance with this Section 5.13(b) or any New Commitment Letter in replacement of the Commitment Letter, as the case may be, and, in the event that Parent or Merger Sub obtains Alternative Financing in accordance with Section 5.13(c), the term “Commitment Letter” shall mean the commitment letter (as amended, replaced, supplemented or modified in accordance with this Section 5.13(b)) related to the Alternative Financing. The term “New Commitment Letter” shall mean the instrument replacing the existing Commitment Letter that (A) is on terms no less beneficial to Parent and its Subsidiaries (after giving effect to the Merger and Subsequent Merger) than those set forth in the Commitment Letter, including as to permitted dividends and the impact of the Financing contemplated thereby on Parent’s credit rating; (B) does not involve any conditions precedent to funding the Financing that are not contained in the Commitment Letter; and (C) would not reasonably be expected to prevent or materially delay the consummation of the transactions contemplated by this Agreement.

               (c) In the event any portion of the Financing becomes unavailable on the terms and conditions contemplated in the Commitment Letter (as such terms may be modified or adjusted in accordance with the terms of, and within the limits of, the “flex” provisions contained in the Commitment Letter or accompanying fee letter) for any reason, each of Parent and Merger Sub shall use its reasonable best efforts to obtain, as promptly as practicable but no later than the Initial Outside Date (or, if applicable, the Extended Outside Date), financing from alternative sources in an amount sufficient to consummate the transactions contemplated by this Agreement and that would not (i) involve any conditions to funding the Financing that are not contained in the Commitment Letter; (ii) reasonably be expected to prevent or materially delay the consummation of the transactions contemplated by this Agreement; and (iii) include terms that would be materially adverse when compared to the terms of the Commitment Letter (an alternative financing meeting the foregoing requirements shall be an “Alternative Financing”). In the event that Alternative Financing shall be obtained pursuant to this Section 5.13(c), Parent and Merger Sub shall comply with the covenants in Section 5.13(b) with respect to such Alternative Financing.

               (d) Parent and Merger Sub shall give the Company prompt written notice of any material breach by any party of the Commitment Letter (or commitments for any Alternative Financing obtained in accordance with this Section 5.13) of which Parent or Merger Sub becomes aware, any termination of the Commitment Letter (or commitments for any Alternative Financing obtained in accordance with this Section 5.13) or any condition precedent of the Financing (or any Alternative Financing obtained in accordance with this Section 5.13) which Parent and Merger Sub have any reason to believe will not be satisfied at the Effective Time, as applicable.

               (e) At Parent’s request, the Company shall, and shall cause the Company Subsidiaries and the Company Representatives to, at Parent’s sole expense, use its and their reasonable best efforts to (x) cooperate with Parent to complete the Financing (or any Alternative Financing) and any other financing or refinancing

transactions undertaken by Parent or any Parent Subsidiary to the extent that information relating to, or the participation by members of management of, the Company is reasonably necessary in connection therewith; and (y) provide all information and assistance that is customarily provided in financings comparable to the proposed Financing or such other financing or refinancing transaction, as the case may be. Without limiting the generality of the foregoing, the Company shall (i) furnish to Parent as promptly as practicable, upon Parent’s request from time to time, all Required Financial Information; (ii) use its reasonable best efforts to furnish to Parent, as promptly as reasonably practicable, other information with respect to the Company reasonably requested by Parent in writing so that Parent may satisfy the applicable SEC requirements for a public capital markets offering as set forth on Section 5.13(e) of the Parent Disclosure Letter (to the extent such matters set forth on such Section 5.13(e) of Parent Disclosure Letter are consistent with SEC requirements); (iii) use its reasonable best efforts to furnish to Parent, as promptly as reasonably practicable, information relating to the Company reasonably requested by Parent in writing (including such requests made after the provision of the Required Financial Information) that is customarily used in the preparation of customary offering or information documents or rating agency, lender presentations or road shows relating to such financing, including the Company Financial Statements and budgets; (iv) upon reasonable advance notice (which notice shall not be less than three Business Days in the event of road shows or other sessions requiring out-of-town travel), participate in a reasonable number of investor presentations, road shows, due diligence sessions and rating agency presentations in connection with such financing; (v) assist with the preparation, including upon reasonable advance notice (subject to the parenthetical in clause (iv) above) participating in a reasonable number of drafting sessions, of one confidential information memorandum, offering memorandum or other offering document, (including any amendments or supplements thereto and an additional version of any confidential information memorandum for use by “public-side” lenders) in connection with any such financing; (vi) request required consents of accountants for use of their reports in any materials relating to any such financing where the inclusion of such reports is necessary and the delivery of customary comfort letters and customary representation letters; (vii) use its reasonable best efforts to facilitate pledging collateral in connection with any debt portion of the Financing from and after the Closing as may be reasonably requested by Parent (provided that any obligations contained in such documents shall be effective no earlier than as of the Closing); (viii) take such corporate actions (subject to the occurrence of the Closing) as are reasonably necessary to complete any such financing; (ix) refrain from syndicating or issuing, attempting to syndicate or issue, announcing or authorizing the announcement of the syndication or issuance of, or engaging in discussions concerning the syndication or issuance of, any debt facility or any debt or equity security of the Company or any Company Subsidiaries, except as set forth in Section 5.13(e) of the Company Disclosure Letter and (x) use reasonable best efforts to facilitate the execution and delivery (at the Closing) of definitive documents related to the Financing. Notwithstanding the foregoing, nothing in this Section 5.13(e) shall require the cooperation or participation of the Company to the extent it would unreasonably interfere with the business or operations of the Company or the Company Subsidiaries or otherwise unreasonably interfere with the prompt and timely discharge by the Company’s or any Company Subsidiary’s employees of their normal duties.

Notwithstanding anything in this Agreement to the contrary, neither the Company nor any of the Company Subsidiaries shall (A) be required to bear any cost or expense or to pay any commitment or other similar fee or make any other payment in connection with the Financing or any of the foregoing prior to the Effective Time, and Parent shall, promptly upon request by the Company, reimburse the Company for all reasonable and documented out-of-pocket costs incurred by the Company, the Company Subsidiaries and the Company Representatives in connection with the Financing or any cooperation pursuant to this Section 5.13(e), (B) have any liability or obligation under any loan agreement or any related document or any other agreement or document related to the Financing (or Alternative Financing), unless and until the Closing occurs or (C) incur any other liability in connection with the Financing (or any Alternative Financing) prior to the Effective Time, other than as expressly contemplated by this Agreement. Notwithstanding the foregoing, nothing in this Agreement shall require the Company Board to take any action to approve the Financing, the Alternative Financing or any other financing in connection with the Merger or Subsequent Merger. Parent and Parent Subsidiaries shall indemnify and hold harmless the Company and the Company Subsidiaries and each of their respective officers, directors, employees, agents, representatives, successors and assigns from and against any and all damages, fees, costs and expenses suffered or incurred by them other than those liabilities, damages, fees, costs and expenses arising out of a material misstatement in or failure to state a material fact pertinent to the information provided by or on behalf of the Company pursuant to this Section 5.13(e), in connection with the arrangement of the Financing (or any Alternative Financing) or the use of any offering documents contemplated by this Section 5.13.

               (f) All non-public or other confidential information provided by the Company pursuant to Section 5.13(e) shall be kept confidential in accordance with Section 5.3 and the Confidentiality Agreement, except that Parent shall be permitted to disclose such information to potential sources of capital and to rating agencies and prospective lenders and investors in connection with marketing any Financing as reasonably required in connection with the Financing, subject to the requirements of applicable Law and customary confidentiality provisions (including confidentiality provisions necessary for the Company to comply with its obligations under Regulation FD promulgated under the Exchange Act).

          5.14 Section 16 Matters. Prior to the Effective Time, the Company Board and the Parent Board, or an appropriate committee of non-employee directors thereof, shall take all such steps as may be required consistent with the interpretive guidance of the SEC so that the disposition by any officer or director of the Company who is a covered person of the Company for purposes of Section 16 of the Exchange Act (“Section 16”) of Shares or other Equity Interests in the Company (including Company Options, RSUs or other derivative securities) or acquisitions of Equity Interests in Parent (including derivative securities) pursuant to this Agreement shall be an exempt transaction under Rule 16b-3 promulgated under the Exchange Act. The Company and Parent shall provide copies of such resolutions to counsel to the other Party.

None of the Company, Parent, Merger Sub and Merger LLC shall adopt treatment inconsistent with this election.

               (d) The Company shall immediately notify Parent, if, at any time before the Effective Time, the Company becomes aware of any fact or circumstance that could reasonably be expected to prevent or impede the Merger and the Subsequent Merger, taken together as a single integrated transaction for U.S. federal income tax purposes, and along with the other transactions effected pursuant to this Agreement, from being treated as a “reorganization” under Section 368(a) of the Code. On the date of effectiveness of the Form S-4 and the Closing Date, the Company shall deliver to counsel duly executed certificates containing such representations as may be reasonably requested by counsel for purposes of rendering the opinions described in Sections 6.2(d) and 6.3(d), the “Company Tax Certificates.”

within the meaning of Section 368(a) of the Code and (ii) the Company and Parent will each be a party to that reorganization within the meaning of Section 368(b) of the Code. In rendering such opinion, Latham & Watkins LLP may rely upon the representations contained herein and may receive and rely upon representations from Parent, the Company, and others, including representations from Parent in the Parent Tax Certificate and representations from the Company in the Company Tax Certificate, in each case, that are reasonably satisfactory to Latham & Watkins LLP.

Parent, Merger Sub and the Company would not enter into this Agreement. It is acknowledged and agreed that the Termination Fees are not a penalty, but rather are liquidated damages representing a reasonable estimate of the amount that would compensate the Company or Parent and Merger Sub in the circumstances in which such Termination Fee is payable, absent an intentional breach of this Agreement. In no event shall the Company be required to pay to Parent more than one Company Termination Fee pursuant to Section 7.2(b) and in no event shall Parent be required to pay to the Company more than one Parent Termination Fee pursuant to Section 7.2(c).

At any time prior to the Effective Time, Parent and Merger Sub, on the one hand, and the Company, on the other hand, may (a) extend the time for the performance of any of the obligations or other acts of the other, (b) waive any breach of the representations and warranties of the other contained herein or in any document delivered pursuant hereto and (c) waive compliance by the other with any of the covenants or conditions contained herein, to the extent permitted by applicable Law; provided, however, that after receipt of the Company Shareholder Approval, there may not be any extension or waiver of this Agreement which decreases the Merger Consideration or which adversely affects the rights of the Company’s shareholders hereunder without the approval of such shareholders at a duly convened meeting of the Company’s shareholders called to obtain approval of such extension or waiver. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party or parties to be bound thereby, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

Notwithstanding the foregoing, each of the parties hereto agrees that it will not bring or support any action, cause of action, claim, cross-claim or third-party claim or any kind of description, whether in law or in equity, whether in contract or in tort or otherwise, against any Financing Source (including, without limitation, the Arranger (as defined in the Commitment Letter)) in any way relating to this Agreement or any of the transactions contemplated by this Agreement or the Financing, including but not limited to any dispute arising out of relating in any way to the Commitment Letter or the performance thereof, in any forum other than the Supreme Court of the State of New York, County of New York, or, if under applicable law exclusive jurisdiction is vested in the federal courts, the United States District Court for the Southern District of New York (and appellate courts thereof); provided, however, that for purposes of any action or claim referred to in this sentence, the interpretation of the definition of Acquired Business Material Adverse Effect and Company Material Adverse Effect (each, as defined in the Commitment Letter), in each case, as set forth the Commitment Letter, shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof.

               (c) EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY INCLUDING BUT NOT LIMITED TO ANY DISPUTE ARISING OUT OF OR RELATING TO THE COMMITMENT LETTER OR THE FINANCING OR THE PERFORMANCE THEREOF. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (II) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (III) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (IV) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8.12(c).

          8.13 Counterparts. This Agreement may be executed in two or more counterparts, and by the different Parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. The exchange of a fully executed Agreement (in counterparts or otherwise) by facsimile or by electronic delivery in .pdf format shall be sufficient to bind the Parties to the terms and conditions of this Agreement.

          8.14 Specific Performance.

               (a) The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in

the event that the Parties hereto do not perform the provisions of this Agreement (including failing to take such actions as are required of it hereunder in order to consummate this Agreement) in accordance with its specified terms or otherwise breach such provisions. The Parties acknowledge and agree that each Party hereto shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, without proof of actual damages (and each Party hereby waives any requirement for the securing or posting of any bond or other undertaking in connection with such remedy), this being in addition to, and not exclusive of, any other remedy to which they are entitled at law or in equity. Without limitation of the foregoing and notwithstanding anything in this Agreement to the contrary, the Parties hereby further acknowledge and agree that prior to the Closing, each Party shall be entitled to seek specific performance (i) to enforce specifically the terms and provisions of, and to prevent or cure breaches of, Section 5.6 and Section 5.13; (ii) if (A) all conditions in Sections 6.1 and 6.2 (other than those conditions that by their nature are to be satisfied at the Closing) have been satisfied or waived and (B) Parent and Merger Sub fail to complete the Closing by the date the Closing is required to have occurred pursuant to Section 1.2, to cause Parent and/or Merger Sub to draw down the full amount of the Financing and (iii) to prevent or cure breaches of this Agreement by the other Party and/or to enforce specifically the terms and provisions of this Agreement, including to cause the other Party to consummate the transactions contemplated hereby, including to effect the Closing in accordance with Section 1.2, on the terms and subject to the conditions in this Agreement. Each Party hereto agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that (x) the other Party has an adequate remedy at law or (y) an award of specific performance is not an appropriate remedy for any reason at law or equity.

               (b) The Parties further agree that (x) the seeking of the remedies provided for in Section 8.14(a) shall not in any respect constitute a waiver by any Party seeking such remedies of its respective right to seek any other form of relief that may be available to it under this Agreement, including under Section 7.2, in the event that this Agreement has been terminated or in the event that the remedies provided for in Section 8.14(a) are not available or otherwise are not granted, and (y) nothing set forth in this Agreement shall require a Party to institute any proceeding for (or limit a Party’s right to institute any proceeding for) specific performance under Section 8.14(a) prior or as a condition to exercising any termination right under Article 7 (and pursuing damages after such termination), nor shall the commencement of any legal proceeding pursuant to Section 8.14(a) or anything set forth in this Section 8.14(b) restrict or limit a Party’s right to terminate this Agreement in accordance with the terms of Article 7 or pursue any other remedies under this Agreement that may be available then or thereafter.

          8.15 Sole and Exclusive Remedy. Notwithstanding anything in this Agreement to the contrary, the sole and exclusive remedy of the Company (whether at law, in equity, in contract, in tort or otherwise) against the Financing Sources for any Financing Failure shall be to terminate this Agreement as provided in Section 7.1(j) and receive payment of the Financing Failure Fee and upon payment of the Financing Failure Fee none of the Financing Sources will have any liability to the Company, its affiliates or

any other Person relating to or arising out of this Agreement, the Commitment Letter or otherwise, whether at law, or equity, in contract, in tort or otherwise, and no Person will have any rights or claims against any of the Financing Sources hereunder or thereunder. In no event shall the Company be entitled to seek the remedy of specific performance of this Agreement against the Financing Sources, and in no event shall any Financing Source be liable for or obligated to pay consequential, special, multiple, punitive or exemplary damages including, but not limited to, damages arising from loss of profits, business opportunities or goodwill in respect of any breach or failure to comply with this Agreement or in respect of any of the transactions contemplated hereby (including the Financing and the Commitment Letter).

     IN WITNESS WHEREOF, Parent, Merger Sub, Merger LLC and the Company have caused this Agreement to be executed as of the date first written above by their respective officers thereunto duly authorized.
