Effect of the Merger on Capital Stock;

Exchange of Certificates

4.1. Effect on Capital Stock. At the Effective Time, as a result of the Merger and without any action on the part of the holder of any capital stock of the Company or the sole stockholder of Merger Sub:

(a) Merger Consideration. Each share of the common stock, par value $0.01 per share, of the Company (a “Share” or, collectively, the “Shares”) issued and outstanding immediately prior to the Effective Time other than (i) Shares owned by Parent, Merger Sub or any other direct or indirect wholly-owned Subsidiary of Parent and Shares owned by the Company or any direct or indirect wholly-owned Subsidiary of the Company, and in each case not held on behalf of third parties (but not including Shares held by the Company in any “rabbi trust” or similar arrangement in respect of any

-3-

compensation plan or arrangement) and (ii) Shares that are owned by stockholders (“Dissenting Stockholders”) who have perfected and not withdrawn a demand for appraisal rights pursuant to Section 262 of the DGCL (each Share referred to in clause (i) or clause (ii) being an “Excluded Share” and collectively, “Excluded Shares”) shall be converted into the right to receive $27.25 per Share in cash, without interest (the “Per Share Merger Consideration”). 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 Excluded Shares) and each non-certificated Share represented by book-entry (a “Book Entry Share”) (other than Excluded Shares) shall thereafter represent only the right to receive the Per Share Merger Consideration, without interest, and each Certificate formerly representing Shares or Book Entry Shares owned by Dissenting Stockholders shall thereafter only represent the right to receive the payment to which reference is made in Section 4.2(f).

(b) Cancellation of Excluded Shares. Each Excluded Share shall, by virtue of the Merger and without any action on the part of the holder thereof, cease to be outstanding, shall be cancelled without payment of any consideration therefor and shall cease to exist, subject to any rights the holder thereof may have under Section 4.2(f).

(c) Merger Sub. At the Effective Time, 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 one share of common stock, par value $0.01 per share, of the Surviving Corporation.

(d) Nonvoting Preferred Stock. Each share of Nonvoting Preferred Stock issued and outstanding at the Effective Time shall remain outstanding following the Effective Time.

4.2. Exchange of Shares.

(a) Paying Agent. Immediately prior to the Effective Time, Parent shall deposit, or shall cause to be deposited, with a paying agent selected by Parent with the Company’s prior approval (such approval not to be unreasonably withheld or delayed) (the “Paying Agent”), for the benefit of the holders of Shares, a cash amount in immediately available funds necessary for the Paying Agent to make payments under Section 4.1(a) (such cash being hereinafter referred to as the “Exchange Fund”). The Paying Agent agreement pursuant to which Parent shall appoint the Paying Agent shall be in form and substance reasonably acceptable to the Company. The Paying Agent shall invest the Exchange Fund as directed by Parent; provided that such investments shall be in obligations of or guaranteed by the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s, respectively, in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $1 billion, or in money market funds having a rating in the highest investment category granted by a recognized credit rating agency at the time of investment. Any interest and other income resulting from

-4-

such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable under Section 4.1(a) shall be promptly returned to the Surviving Corporation. To the extent that there are any losses with respect to any such investments, or the Exchange Fund diminishes for any reason below the level required for the Paying Agent to make prompt cash payment under Section 4.1(a), Parent shall, or shall cause the Surviving Corporation to, promptly replace or restore the cash in the Exchange Fund so as to ensure that the Exchange Fund is at all times maintained at a level sufficient for the Paying Agent to make such payments under Section 4.1(a).

(b) Exchange Procedures. (i) Promptly after the Effective Time (and in any event within two business days), the Surviving Corporation shall cause the Paying Agent to mail to each holder of record of a Certificate representing Shares (other than holders of Excluded Shares) (A) a letter of transmittal in customary form specifying that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates (or affidavits of loss in lieu thereof as provided in Section 4.2(e)) to the Paying Agent, such letter of transmittal to be in such form and have such other provisions as Parent and the Company may reasonably agree, and (B) instructions for use in effecting the surrender of the Certificates (or affidavits of loss in lieu thereof as provided in Section 4.2(e)) in exchange for the Per Share Merger Consideration. Upon surrender of a Certificate (or affidavit of loss in lieu thereof as provided in Section 4.2(e)) to the Paying Agent in accordance with the terms of such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor a cash amount in immediately available funds (after giving effect to any required Tax withholdings as provided in Section 4.2(g)) equal to (x) the number of Shares represented by such Certificate (or affidavit of loss in lieu thereof as provided in Section 4.2(e)) multiplied by (y) the Per Share Merger Consideration, and the Certificate so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any amount payable upon due surrender of the Certificates. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, a check for any cash to be exchanged upon due surrender of the Certificate may be issued to such transferee if the Certificate formerly representing such Shares is presented to the Paying Agent, accompanied by all documents reasonably required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid or are not applicable.

(ii) Notwithstanding anything to the contrary in this Agreement, any holder of Book Entry Shares shall not be required to deliver a Certificate or an executed letter of transmittal to the Paying Agent to receive the Per Share Merger Consideration that such holder is entitled to receive pursuant to this Article IV. In lieu thereof, each holder of record of one or more Book Entry Shares whose Shares were converted into the right to receive the Per Share Merger Consideration shall upon receipt by the Paying Agent of an “agent’s message” in customary form (or such other evidence, if any, as the Paying Agent may reasonably request), be entitled to receive, and Parent shall cause the Paying Agent to pay and deliver as promptly as reasonably practicable after the Effective Time, the Per Share Merger Consideration in respect of each such Share and the Book Entry Shares of such holder shall forthwith be cancelled.

-5-

(c) Transfers. From and after the Effective Time, there shall be no transfers on the stock transfer books of the Company of the Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificate or Book Entry Share is presented to the Surviving Corporation, Parent or the Paying Agent for transfer, it shall be cancelled and exchanged for the cash amount in immediately available funds to which the holder thereof is entitled pursuant to this Article IV.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund (including the proceeds of any investments thereof) that remains unclaimed by the stockholders of the Company 180 days after the Effective Time shall be delivered to the Surviving Corporation. Any holder of Shares (other than Excluded Shares) who has not theretofore complied with this Article IV shall thereafter look only to the Surviving Corporation for payment of the Per Share Merger Consideration (after giving effect to any required Tax withholdings as provided in Section 4.2(g)) upon due surrender of its Certificates (or affidavits of loss in lieu thereof as provided in Section 4.2(e)) or Book Entry Shares, without any interest thereon. Notwithstanding the foregoing, none of the Surviving Corporation, Parent, the Paying Agent or any other Person shall be liable to any former holder of Shares for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. For the purposes of this Agreement, the term “Person” shall mean any individual, corporation (including not-for-profit), general or limited partnership, limited liability company, joint venture, estate, trust, association, organization, Governmental Entity or other entity of any kind or nature.

(e) Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond in customary amount and upon such terms as may be required by Parent as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Paying Agent will issue a check in the amount (after giving effect to any required Tax withholdings as provided in Section 4.2(g)) equal to (i) the number of Shares represented by such lost, stolen or destroyed Certificate multiplied by (ii) the Per Share Merger Consideration.

(f) Appraisal Rights. No Person who has perfected a demand for appraisal rights pursuant to Section 262 of the DGCL shall be entitled to receive the Per Share Merger Consideration with respect to the Shares owned by such Person unless and until such Person shall have effectively withdrawn or lost such Person’s right to appraisal under the DGCL. Each Dissenting Stockholder shall be entitled to receive only the payment provided by Section 262 of the DGCL with respect to Shares owned by such Dissenting Stockholder. The Company shall give Parent (i) prompt notice of any demands for appraisal, threatened demands for appraisal, attempted withdrawals of such demands, and any other instruments that are received by the Company relating to

-6-

stockholders’ rights of appraisal (any of the foregoing, a “Demand”) and (ii) the opportunity to participate in and control all negotiations and proceedings with respect to any Demand. The Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to any Demand, offer to settle or settle any such Demand.

(g) Withholding Rights. Each of the Company, Parent, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares, Company RSUs, Company PSUs and Company Awards (each as defined in Section 4.3) such amounts as it is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”) or any other applicable state, local or foreign Tax Law. To the extent that amounts are so withheld by the Company, the Surviving Corporation, Parent or the Paying Agent, as the case may be, such withheld amounts (i) shall be remitted by the Company, Parent, the Surviving Corporation or the Paying Agent, as applicable, to the applicable Governmental Entity, and (ii) shall be treated for all purposes of this Agreement as having been paid to the holder of Shares in respect of which such deduction and withholding was made by the Company, the Surviving Corporation, Parent or the Paying Agent, as the case may be.

4.3. Treatment of Stock Plans.

(a) Company Restricted Stock Units. At the Effective Time, each outstanding Company restricted stock unit that vests based solely on continued service to the Company and its Subsidiaries (a “Company RSU”) under the Stock Plans (as defined in Section 5.1(b)), vested or unvested, shall be cancelled and converted into the right of the holder thereof to receive, as soon as reasonably practicable (but no later than three business days) after the Effective Time (or, to the extent such Company RSU is deferred compensation subject to Section 409A of the Code, at the earliest time permitted under the applicable Stock Plan or Benefit Plan that will not trigger a tax or penalty under Section 409A of the Code, with interest at the U.S. prime rate as shown at the end of the day on Bloomberg screen BTMM or PRIME INDEX HP, whichever is higher (the “Interest Rate”) from the Closing Date through such payment date), an amount in cash equal to the product of (x) the total number of Shares subject to such Company RSU immediately prior to the Effective Time, multiplied by (y) the Per Share Merger Consideration; provided, however, that any Company RSUs granted after the date hereof will only payout on a prorated basis based on the number of days elapsed from the grant date (or, in the case of the annual 2015 grants, January 1, 2015) through the Closing Date relative to 1,095 days (and the remainder of such awards will be cancelled without payment).

(b) Company Performance Stock Units. At the Effective Time, each outstanding Company restricted stock unit that vests, in whole or in part, based on the achievement of performance objectives (a “Company PSU”) under the Stock Plans, vested or unvested, shall be cancelled and converted into the right of the holder thereof to

-7-

receive, as soon as reasonably practicable (but no later than three business days) after the Effective Time (or, to the extent such Company PSU is deferred compensation subject to Section 409A of the Code, at the earliest time permitted under the applicable Stock Plan or Benefit Plan that will not trigger a tax or penalty under Section 409A of the Code, with interest at the Interest Rate from the Closing Date through such payment date), an amount in cash equal to the product of (x) the total number of Shares subject to such Company PSU immediately prior to the Effective Time, determined (without proration) based on achievement of applicable performance objectives at the greater of (1) actual performance as reasonably determined by the compensation committee of the board of directors of the Company prior to the Effective Time based on performance through a day that is no more than five business days prior to the Effective Time and (2) the target level of 100%, multiplied by (y) the Per Share Merger Consideration; provided, however, that any Company PSUs granted after the date hereof (other than Company PSUs required to be granted pursuant to the terms of an agreement in place as of the Original Execution Date, which will be treated as described above in this Section 4.3(b)) will have performance determined based on the greater of (1) actual performance (determined as described above in this Section 4.3(b)) and (2) the target level of 100%, and will only payout on a prorated basis based on the number of days elapsed from the grant date (or, in the case of the annual 2015 grants, January 1, 2015) through the Closing Date relative to 1,095 days (and the remainder of such awards will be cancelled without payment).

(c) Company Awards. At the Effective Time, each right of any kind, contingent or accrued, vested or unvested, to acquire or receive Shares or benefits measured by the value of Shares, and each award of any kind consisting of Shares that may be held, awarded, outstanding, payable or reserved for issuance under the Stock Plans and any other Benefit Plans, other than Company RSUs and Company PSUs (the “Company Awards”), shall be cancelled and shall only entitle the holder thereof to receive, as soon as reasonably practicable after the Effective Time (or, to the extent such Company Award is deferred compensation subject to Section 409A of the Code, at the earliest time permitted under the applicable Stock Plan or Benefit Plan that will not trigger a tax or penalty under Section 409A of the Code, with interest at the Interest Rate from the Closing Date through such payment date), an amount in cash equal to (x) the number of Shares subject to such Company Award immediately prior to the Effective Time determined (without proration) based on achievement of any applicable performance objectives at the greater of (1) actual performance as reasonably determined by the compensation committee of the board of directors of the Company prior to the Effective Time based on performance through a day that is no more than five business days prior to the Effective Time and (2) the target level of 100%, multiplied by (y) the Per Share Merger Consideration (or, if the Company Award provides for payments to the extent the value of the Shares exceeds a specified reference or exercise price, the amount, if any (or zero, if no such excess), by which the Per Share Merger Consideration exceeds such reference or exercise price).

-8-

(d) Corporate Actions. At or prior to the Effective Time, the Company, the board of directors of the Company and the compensation committee of the board of directors of the Company, as applicable, shall adopt any resolutions and take any actions which are necessary to effectuate the provisions of Sections 4.3(a) through 4.3(c).

4.4. Adjustments to Prevent Dilution. In the event that the Company changes the number of Shares or securities convertible or exchangeable into or exercisable for Shares issued and outstanding prior to the Effective Time as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, issuer tender or exchange offer, or other similar transaction, the Per Share Merger Consideration shall be equitably adjusted.

ARTICLE V

Representations and Warranties

5.1. Representations and Warranties of the Company.

This Agreement has been duly executed and delivered by the Company and constitutes a valid and binding agreement of the Company enforceable against the Company in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar Laws of general applicability relating to or affecting creditors’ rights and to general equity principles (the “Bankruptcy and Equity Exception”).

holders of Shares in the Merger is fair from a financial point of view, as of the date of such opinions, to such holders.

(vi) No amount that could be received (whether in cash or property or the vesting of property), as a result of the consummation of the Merger, by any employee, director or other individual service provider of the Company or its Subsidiaries under any Benefit Plan or otherwise would not be deductible by reason of Section 280G of the Code or would be subject to an excise tax under Section 4999 of the Code, except as would not individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect.

Except with respect to regulatory matters covered by Section 6.5, no investigation or review by any Governmental Entity, NERC or PJM with respect to the Company or any of its Subsidiaries is pending or, to the Knowledge of the Company, threatened, nor has any Governmental Entity indicated an intention to conduct the same, except for such investigations or reviews, the outcome of which is not, individually or in the aggregate, reasonably likely to have a Company Material Adverse Effect.

Except as set forth in any forms, statements, certifications, reports or documents filed with or furnished to the SEC by Parent prior to the date hereof, or the corresponding sections or subsections of the disclosure letter delivered to the Company by Parent prior to entering into this Agreement (the “Parent Disclosure Letter”) (it being agreed that disclosure of any item in any section or subsection of the Parent Disclosure Letter shall be deemed disclosure with respect to any other section or subsection to which the relevance of such item is reasonably apparent), Parent and Merger Sub each hereby represent and warrant to the Company that:

Parent has made available to the Company a complete and correct copy of the certificate of incorporation and bylaws or comparable governing documents of Parent and Merger Sub, each as in effect on the date of this Agreement.

This Agreement has been duly executed and delivered by each of Parent and Merger Sub and is a valid and binding agreement of Parent and Merger Sub, enforceable against each of Parent and Merger Sub in accordance with its terms, subject to the Bankruptcy and Equity Exception. The representations and warranties set forth in this Section 5.2(a) shall be made with respect to the Original Merger Agreement as of the Original Execution Date and with respect to the Amended and Restated Agreement as of the Execution Date.

(ii) The execution, delivery and performance of this Agreement by Parent and Merger Sub do not, and the consummation by Parent and Merger Sub of the Merger and the other transactions contemplated hereby will not, constitute or result in (A) a breach or violation of, or a default under, the certificate of incorporation, certificate of formation or bylaws or comparable governing documents of Parent or Merger Sub or the comparable governing instruments of any of its Subsidiaries; (B) with or without notice, lapse of time or both, a breach or violation of, a termination (or right of termination) or a default under, the creation or acceleration of any obligations or the creation of a Lien on any of the assets of Parent or any of its Subsidiaries pursuant to, any Contracts binding upon

-25-

Parent or any of its Subsidiaries or any Laws or governmental or non-governmental permit or license to which Parent or any of its Subsidiaries is subject; or (C) any change in the rights or obligations of any party under any of such Contracts, except, in the case of clause (B) or (C) above, for any breach, violation, termination, default, creation, acceleration or change that would not, individually or in the aggregate, reasonably be expected to prevent or materially delay the ability of Parent or Merger Sub to consummate the Merger and the other transactions contemplated by this Agreement.

(d) Litigation. There are no civil, criminal or administrative actions, suits, claims, hearings, investigations or proceedings pending or, to the Knowledge of Parent, threatened against Parent or Merger Sub by or before any Governmental Entity that seek to enjoin, or would reasonably be expected to have the effect of preventing, making illegal, or otherwise interfering with, any of the transactions contemplated by this Agreement, except as would not, individually or in the aggregate, reasonably be expected to prevent or materially delay the ability of Parent and Merger Sub to consummate the Merger and the other transactions contemplated by this Agreement.

The term “Knowledge” when used in this Agreement with respect to Parent shall mean the actual knowledge of the Chief Executive Officer, Chief Financial Officer and General Counsel.

(e) Available Funds. Parent and Merger Sub will have available to them on or before the Effective Time all funds necessary for the payment to the Paying Agent of the aggregate Per Share Merger Consideration and to satisfy all of their obligations under this Agreement, including amounts payable under Section 4.3. Parent currently has available to it all funds necessary for the payment to the Company of the aggregate consideration payable for the Nonvoting Preferred Stock to be issued, sold and delivered by the Company to Parent on the date hereof pursuant to the Subscription Agreement.

(f) Capitalization of Merger Sub. The authorized capital stock of Merger Sub consists solely of 1,000 shares of common stock, par value $0.01 per share, all of which are validly issued and outstanding. All of the issued and outstanding capital stock of Merger Sub is, and at the Effective Time will be, owned by Parent or a direct or indirect wholly-owned Subsidiary of Parent. Merger Sub has not conducted any business prior to the date hereof and has no, and prior to the Effective Time will have no, assets, liabilities or obligations of any nature other than those incident to its formation and pursuant to this Agreement and the Merger and the other transactions contemplated by this Agreement.

(g) Regulatory Matters. Each of Parent’s Subsidiaries that engages in the sale of electricity at wholesale (other than any such Subsidiaries that own one or more facilities that constitute a “qualifying facility” as such term is defined under the Public Utility Regulatory Policies Act of 1978 and the rules and regulations of FERC that are

-26-

entitled to exemption from regulation under Section 205 of the Federal Power Act) is regulated as a “public utility” under the Federal Power Act and has market-based rate authorization to make such sales at market-based rates. Each of Parent’s Subsidiaries that directly owns generating facilities and operates their power generation facilities is in compliance with all applicable standards of NERC, other than non-compliance that would not reasonably be expected to prevent, materially delay or impair Parent from consummating the Merger and the other transactions contemplated by the Agreement or have, individually or in the aggregate, a material impact on Parent. There are no pending, or to the Knowledge of Parent, threatened, judicial or administrative proceedings (i) that would reasonably be expected to interfere with Parent’s timely receipt of the Regulatory Approvals or (ii) that would revoke a Parent’s Subsidiary’s market-based rate authorization.

(h) Foreign Ownership, Control or Influence. Each officer and manager of Parent is a U.S. citizen, and to the Knowledge of Parent, none of the holders owning 5% or more of Parent’s equity interests is, or is controlled by, a foreign Person or entity.

(i) Brokers. No agent, broker, finder or investment banker is entitled to any brokerage, finder’s or other fee or commission in connection with the transactions contemplated by this Agreement based upon arrangements made by or on behalf of Parent or Merger Sub for which the Company could have any liability.

(j) Non-Reliance on Company Estimates, Projections, Forecasts, Forward-Looking Statements and Business Plans. In connection with the due diligence investigation of the Company by Parent and Merger Sub, Parent and Merger Sub have received and may continue to receive from the Company certain estimates, projections, forecasts and other forward-looking information, as well as certain business plan and cost-related plan information, regarding the Company, its Subsidiaries and their respective businesses and operations. Parent and Merger Sub hereby acknowledge that there are uncertainties inherent in attempting to make such estimates, projections, forecasts and other forward-looking statements, with which Parent and Merger Sub are familiar, that Parent and Merger Sub are taking full responsibility for making their own evaluation of the adequacy and accuracy of all estimates, projections, forecasts and other forward-looking information, as well as such business plans and cost-related plans, so furnished to them (including the reasonableness of the assumptions underlying such estimates, projections, forecasts, forward-looking information, business plans or cost-related plans), and that Parent and Merger Sub will have no claim against the Company or any of its Subsidiaries, or any of their respective stockholders, directors, officers, employees, Affiliates, advisors, agents or representatives, or any other Person, with respect thereto. Accordingly, Parent and Merger Sub hereby acknowledge that neither the Company nor any of its Subsidiaries, nor any of their respective stockholders, directors, officers, employees, Affiliates, advisors, agents or representatives, nor any other Person, has made or is making any representation or warranty with respect to such estimates, projections, forecasts, forward-looking statements, business plans or cost-related plans (including the reasonableness of the assumptions underlying such estimates, projections, forecasts, forward-looking statements, business plans or cost-related plans).

Prior to the Effective Time, each of Parent and the Company shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations.

6.2. Acquisition Proposals.

(a) No Solicitation or Negotiation. The Company agrees that except as expressly permitted by this Section 6.2, neither it nor any of its Subsidiaries, nor any of its or their respective directors, officers or employees, shall, and that it shall instruct and use its reasonable best efforts to cause its and its Subsidiaries’ investment bankers, attorneys, accountants and other advisors and representatives not to (such investment bankers, attorneys, accountants and other advisors and representatives, collectively, “Representatives”), directly or indirectly:

(i) initiate, solicit or encourage any inquiries or the making of any proposal or offer that constitutes, or could reasonably be expected to lead to, any Acquisition Proposal;

(ii) engage in, continue or otherwise participate in any discussions or negotiations regarding, or provide any non-public information or data to any Person relating to, or that could reasonably be expected to lead to, any Acquisition Proposal;

(iii) facilitate knowingly any effort or attempt to make an Acquisition Proposal;

-32-

(v) execute or enter into any letter of intent, agreement in principle, term sheet, memorandum of understanding, merger agreement, acquisition agreement or other similar agreement relating to an Acquisition Proposal (other than an Acceptable Confidentiality Agreement) (an “Alternative Acquisition Agreement”); or

(vi) resolve or agree to do any of the foregoing.

(b) Notwithstanding anything in the foregoing to the contrary, prior to the time, but not after, the Company Requisite Vote is obtained, the Company may (A) provide information in response to a request therefor by a Person who has made an unsolicited bona fide written Acquisition Proposal if prior to providing such information the Company receives from the Person so requesting such information an executed confidentiality agreement on terms that are not less restrictive to the other party than those contained in the Confidentiality Agreement, it being understood that such confidentiality agreement need not prohibit the making, or amendment, of an Acquisition Proposal (an “Acceptable Confidentiality Agreement”); and promptly discloses (and, if applicable, provides copies of) any such information to Parent to the extent not previously disclosed or provided; (B) engage or participate in any discussions or negotiations with any Person who has made such an unsolicited bona fide written Acquisition Proposal; or (C) after having complied with Section 6.2(d), make a Change of Recommendation or approve, recommend, or otherwise declare advisable or propose to approve, recommend or declare advisable (publicly or otherwise) with respect to such Acquisition Proposal; if and only to the extent that, (x) prior to taking any action described in clause (A), (B) or (C) above, the board of directors of the Company shall have determined in good faith, after consultation with its outside legal counsel, that failure to take such action would be reasonably likely to be inconsistent with the directors’ fiduciary duties under applicable Law, (y) in each case referred to in clause (A) and (B), the board of directors of the Company shall have determined in good faith, after consultation with its financial advisors and outside legal counsel, that such Acquisition Proposal either constitutes a Superior Proposal or is reasonably likely to result in a Superior Proposal, and (z) in the case referred to in clause (C) above, the board of directors of the Company determines in good faith (after consultation with its financial advisor and outside legal counsel) that such Acquisition Proposal is a Superior Proposal.

“Acquisition Proposal” means (i) any proposal or offer with respect to a merger, joint venture, partnership, consolidation, dissolution, liquidation, tender offer, recapitalization, reorganization, share exchange, business combination or similar transaction involving the Company and/or any of its Significant Subsidiaries or (ii) any

-33-

direct or indirect acquisition by any Person or “group” (as defined in the Exchange Act) resulting in, or proposal or offer, which if consummated would result in, any Person or “group” (as defined in the Exchange Act) becoming the beneficial owner, directly or indirectly, in one or a series of related transactions, of 15% or more of the total voting power or of any class of equity securities of the Company, or assets representing 15% or more of the net revenues, net income or consolidated total assets (measured by fair market value) of the Company and its Subsidiaries, taken as a whole (including equity securities of its Subsidiaries), in each case other than the Merger.

“Superior Proposal” means a bona fide Acquisition Proposal (for purposes of this definition, replacing all references in the definition of “Acquisition Proposal” to 15% with 75%), that the board of directors of the Company has determined in its good faith judgment is reasonably likely to be consummated in accordance with its terms, after consultation with its financial advisors and outside legal counsel, taking into account all legal, financial, and regulatory aspects of the Acquisition Proposal, and the Person making the Acquisition Proposal, and, if consummated would result in a transaction more favorable to the Company’s stockholders from a financial point of view than the transaction contemplated by this Agreement (after taking into account any proposed revisions to the terms of the transactions contemplated by Section 6.2(d) of this Agreement).

(d) No Change in Recommendation or Alternative Acquisition Agreement. The board of directors of the Company and each committee of the board of directors shall not:

(i) (A) withhold, withdraw, qualify or modify (or publicly propose or resolve to withhold, withdraw, qualify or modify), in a manner adverse to Parent, the Company Recommendation (B) fail to include the Company Recommendation in the Proxy Statement, (C) approve, recommend or otherwise declare advisable or propose or resolve to approve, recommend or otherwise declare advisable (publicly or otherwise), any Acquisition Proposal, or (D) fail to publicly reaffirm the Company Recommendation within ten business days after Parent so requests in writing (provided, that Parent shall be entitled to make such a written request for reaffirmation only once for each Acquisition Proposal and once for each material amendment to such Acquisition Proposal) (any action described in clauses (A) and (D) a “Change of Recommendation”); or

(ii) Except as expressly permitted by, and after compliance with this Section 6.2(d), cause or permit the Company to enter into any Alternative Acquisition Agreement.

Notwithstanding anything to the contrary set forth in this Agreement, prior to the time, but not after, the Company Requisite Vote is obtained, the board of directors of the Company (x) may make a Change of Recommendation and in connection therewith, approve, recommend or otherwise declare advisable, and enter into an

-34-

Alternative Acquisition Agreement in connection with a Superior Proposal made after the date of this Agreement (if such Superior Proposal did not result from a material breach of Section 6.2(a) and such Superior Proposal is not withdrawn) or (y) may make a Change of Recommendation as a result of the occurrence of an Intervening Event, if, the board of directors of the Company determines in good faith, after consultation with its outside legal counsel, that failure to do so would be reasonably likely to be inconsistent with the directors’ fiduciary duties under applicable Law; provided, however, that the board of directors of the Company shall not (i) in the case of clause (x) make a Change of Recommendation with respect to a Superior Proposal and authorize the Company to enter into any Alterative Acquisition Agreement or (ii) in the case of clause (y) make a Change of Recommendation unless:

(i) the Company has notified Parent in writing that it intends to effect a Change of Recommendation, describing in reasonable detail the reasons for such Change of Recommendation (a “Recommendation Change Notice”) (it being agreed that the Recommendation Change Notice and any amendment or update to such notice and the determination to so deliver such notice, or update or amend public disclosures with respect thereto shall not constitute a Change of Recommendation for purposes of this Agreement), and if such proposed Change of Recommendation relates to an Acquisition Proposal, has provided copies of the most current version of all documents relating to such Acquisition Proposal, and if such proposed Change of Recommendation relates to an Intervening Event, such Recommendation Change Notice specifies the facts and circumstances of such Intervening Event; and

(ii) (x) if requested by Parent, the Company shall have made its Representatives available to discuss and negotiate in good faith with Parent and its Representatives any proposed modifications to the terms and conditions of this Agreement during the three business days following the date on which the Recommendation Change Notice is delivered to Parent and (y) if Parent shall have delivered to the Company a written, binding and irrevocable offer to alter the terms or conditions of this Agreement during such three business day period, the board of directors of the Company shall have determined in good faith after consultation with its financial advisors and outside legal counsel, after considering the terms of such offer by Parent, that the failure to effect a Change of Recommendation would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law, and that in the case of a Change of Recommendation with respect to an Acquisition Proposal, such Acquisition Proposal would continue to constitute a Superior Proposal if the changes offered by Parent were given effect, and that in the case of an Intervening Event, the board of directors of the Company still intends to effect a Change of Recommendation if the changes offered by Parent were given effect; provided that in the event the Acquisition Proposal is thereafter modified by the party making such Acquisition Proposal, the Company shall notify Parent in writing of such modified Acquisition Proposal and shall again comply with the requirements of this clause (ii).

-35-

“Intervening Event” shall mean any change, event or occurrence that is (a) unknown to or by the board of directors of the Company as of the date of this Agreement (or if known, the magnitude or material consequences of which were not known or understood by the board of directors of the Company as of the date of this Agreement) and (b) becomes known to or by the board of directors of the Company prior to obtaining the Company Requisite Vote.

(e) Certain Permitted Disclosure. Nothing contained in this Section 6.2 shall be deemed to prohibit the Company or the board of directors of the Company from (i) complying with its disclosure obligations under U.S. federal or state Law with regard to an Acquisition Proposal, including taking and disclosing to its stockholders a position contemplated by Rule 14d-9 or Rule 14e-2(a) under the Exchange Act (or any similar communication to stockholders); or (ii) making any “stop, look and listen” communication to the stockholders of the Company pursuant to Rule 14d-9(f) under the Exchange Act.

(f) Existing Discussions. The Company agrees that it and its Subsidiaries will, and that it will instruct and use its reasonable best efforts to cause its and its Subsidiaries’ Representatives to immediately cease and cause to be terminated any existing activities, discussions or negotiations with any parties conducted heretofore with respect to any Acquisition Proposal. The Company agrees that it will take the necessary steps to promptly inform the individuals or entities referred to in the first sentence hereof of the obligations undertaken in this Section 6.2.

(g) Notice. The Company agrees that it will promptly (and, in any event, within 24 hours) notify Parent if any proposals or offers with respect to an Acquisition Proposal are received by, any non-public information is requested from, or any discussions or negotiations are sought to be initiated or continued with, the Company or any of its Representatives indicating, in connection with such notice, the identity of the Person or group of Persons making the proposal, offer or request and the material terms and conditions of any proposals or offers (including, if applicable, copies of any written requests, proposals or offers, including proposed agreements) and thereafter shall keep Parent reasonably informed, on a prompt basis (and, in any event, within 24 hours), of the status and terms of any such proposals or offers (including any material amendments thereto or any change to the scope or material terms or conditions thereof, and including copies of additional written materials or material modifications thereof) and the status of any such discussions or negotiations, including any change in the Company’s intentions as previously notified.

6.3. Proxy Statement.

(a) The Company shall, as promptly as practicable after the date of this Agreement (and in any event on or prior to July 24, 2014), prepare and file a proxy statement in preliminary form relating to the Stockholders Meeting (such proxy statement, including any amendment or supplement thereto, the “Proxy Statement”) with

-36-

the SEC. The Company agrees that as of the date of mailing to stockholders of the Company and at the time of the Stockholders Meeting, (i) the Proxy Statement will comply in all material respects with the applicable provisions of the Exchange Act and the rules and regulations thereunder and (ii) none of the information supplied by it or any of its Subsidiaries for inclusion or incorporation by reference in the Proxy Statement will contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Parent and Merger Sub agree that none of the information supplied by either of them or any of their Affiliates for inclusion in the Proxy Statement will contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

(b) The Company shall promptly notify Parent of the receipt of all comments from the SEC with respect to the Proxy Statement and of any request by the SEC for any amendment or supplement thereto or for additional information and shall promptly provide to Parent copies of all correspondence between the Company and/or any of its Representatives and the SEC with respect to the Proxy Statement. The Company and Parent shall each use its reasonable best efforts to promptly provide responses to the SEC with respect to all comments received on the Proxy Statement from the SEC.

The Company and Parent will each request early termination of the waiting period with respect to the Merger under the HSR Act. Subject to applicable Laws relating to the exchange of information, Parent and the Company shall have the right to review in advance and, to the extent practicable, each will consult with the other on and consider in good faith the views of the other in connection with, all of the information relating to Parent or the Company, as the case may be, and any of their respective Subsidiaries, that appears in any filing made with, or written materials submitted to, any third party and/or any Governmental Entity in connection with the Merger (including the Proxy Statement). In exercising the foregoing rights, each of the Company and Parent shall act reasonably and as promptly as practicable.

Subject to applicable Laws relating to the exchange of information and except as otherwise provided in this

-38-

Agreement, Parent and the Company shall have the right to review in advance, and to the extent practicable each will consult with the other regarding, and consider in good faith the views of the other in connection with, all of the information relating to Parent or the Company, as the case may be, and any of their respective Affiliates and Representatives, that appears in any filing made with, or written materials submitted to, any Governmental Entity in connection with the Merger and the other transactions contemplated by this Agreement. In exercising the foregoing rights, each of the Company and Parent shall act reasonably and as promptly as practicable.

(c) Status. Subject to applicable Laws and the instructions of any Governmental Entity, the Company and Parent each shall keep the other apprised of the status of matters relating to completion of the transactions contemplated hereby, including promptly furnishing the other with copies of notices or other communications received by Parent or the Company, as the case may be, or any of their respective Representatives, from any third party and/or any Governmental Entity with respect to the Merger; provided, however, that either party may designate information or notices or other communications as “for outside counsel only”. Neither the Company nor Parent shall permit any of its officers or any other Representatives to participate in any meeting or substantive telephone discussion with any Governmental Entity in respect of any filings, investigation or other inquiry with respect to the Merger unless to the extent practicable (i) it consults with the other party in advance and (ii) and to the extent permitted by such Governmental Entity, gives the other party the opportunity to attend and participate in such meeting or substantive telephone discussion.

(d) Regulatory Matters. Subject to the terms and conditions set forth in this Agreement, without limiting the generality of the other undertakings pursuant to this Section 6.5, each of the Company (in the case of Sections 6.5(d)(i) and 6.5(d)(iii) set forth below) and Parent (in all cases set forth below) agree to take or cause to be taken the following actions:

(i) the prompt provision to each and every federal, state, local or foreign court or Governmental Entity (including the FERC, the FCC and the State Commissions) with jurisdiction over any Company Approvals or Parent Approvals of non-privileged information and documents requested by any such Governmental Entity that are necessary, proper or advisable to permit consummation of the Merger;

(ii) the prompt use of its reasonable best efforts to avoid the entry or enactment of any permanent, preliminary or temporary injunction or other order, decree, decision, determination, judgment or Law that would delay, restrain, prevent, enjoin or otherwise prohibit consummation of the Merger; and

-39-

(iii) the prompt use of its reasonable best efforts to take, in the event that any permanent, preliminary or temporary injunction, decision, order, judgment, determination, decree or Law is entered, issued or enacted, or becomes reasonably foreseeable to be entered, issued or enacted, in any proceeding, review or inquiry of any kind that would make consummation of the Merger in accordance with the terms of this Agreement unlawful or that would delay, restrain, prevent, enjoin or otherwise prohibit consummation of the Merger, any and all steps (including the appeal thereof, the posting of a bond or the taking of the steps contemplated by clause (ii) of this Section 6.5(d)) necessary to resist, vacate, modify, reverse, suspend, prevent, eliminate, avoid or remove such actual, anticipated or threatened injunction, decision, order, judgment, determination, decree or enactment so as to permit such consummation on a schedule as close as possible to that contemplated by this Agreement;

provided that nothing herein shall require (and reasonable best efforts shall in no event require) any party or its Subsidiaries to agree to or take any action that would otherwise constitute a Burdensome Condition. A “Burdensome Condition” shall mean any terms, conditions, liabilities, obligations, commitments or sanctions imposed upon Parent, the Company or their respective Subsidiaries (A) in the Regulatory Approvals, or (B) in any Laws enacted for the purpose of imposing terms, conditions, liabilities, obligations, commitments or sanctions in connection with the Merger (any of the foregoing in clause (B) a “Merger Law”), that, individually or in the aggregate, would constitute or be reasonably likely to constitute a Regulatory Failure (as defined below), provided, however, that any such terms, conditions, liabilities, obligations, commitments or sanctions shall not be taken into account in determining whether there has been or is such a Regulatory Failure to the extent they implement the Regulatory Commitments. A “Regulatory Failure” shall mean terms, conditions, liabilities, obligations, commitments or sanctions (giving effect to the value of any negative effects net of their benefits) that in an aggregate amount constitute a material and adverse effect on the condition (financial or otherwise), assets, liabilities, businesses or results of operations of the Company and its Subsidiaries, taken as a whole, provided, that, for the purposes of determining the existence of a Regulatory Failure, (i) the Company and its Subsidiaries shall be deemed to have 50% of the assets, liabilities, businesses and results of operations of the Company and its Subsidiaries, taken as a whole, and (ii) any terms, conditions, liabilities, obligations, commitments or sanctions imposed upon Parent and its Subsidiaries shall be deemed to have been imposed on the Company and its Subsidiaries.

(e) Regulatory Commitments. The Company and Parent agree (i) that the applications submitted to FERC and the State Commissions with respect to the Merger shall include the information concerning the Merger, the Company and its Subsidiaries, and Parent required by applicable Laws of the District of Columbia, the States of Delaware, Maryland, and New Jersey, the Commonwealth of Virginia and such other jurisdictions as may be mutually determined by the Company and Parent, as the case may be, (ii) that such applications and any amendments or supplements thereto shall include the Regulatory Commitments to the extent applicable to such jurisdictions and such additional agreements or commitments as the Company and Parent agree are advisable to obtain prompt approval of such applications, and (iii) that neither the Company nor Parent shall agree to, or accept, any additional or different agreements,

-40-

commitments or conditions in connection with the Merger pursuant to any settlement or otherwise with any State Commissions or any other Person, in the case of any agreement, commitment or condition to which the Company of any of its Subsidiaries is a party or otherwise affecting the Company or any of its Subsidiaries, without the prior written consent of Parent, and in the case of any agreement, commitment or condition to which Parent is a party and affecting the Company or any of its Subsidiaries, without the prior written consent of the Company if such agreement, commitment or condition is effective prior to the Effective Time. Parent further agrees that, subject to obtaining the consent of the Company as required by this Section 6.5(e), it will agree to, or accept, any additional or different agreements, commitments or conditions that do not, individually or in the aggregate, constitute a Burdensome Condition to obtain any governmental approvals necessary to promptly consummate the Merger, including any Parent Approval or the FERC Approval, the State Approvals and the FCC Approval.

(f) Rate Cases. Between the date of this Agreement and the Closing, the Company and its Subsidiaries shall be permitted to continue to diligently pursue the rate cases set forth on Section 6.5(f) of the Company Disclosure Letter (collectively, the “Rate Cases”) consistent with past practice, and to the extent permitted by Law, notify Parent about any material developments, or material communications with the FERC or the applicable State Commission, relating thereto. Except as required by Exhibit B, prior to making any commitments or settlement offers in the Rate Cases, the Company shall (and shall cause its Subsidiaries to) consult with Parent and consider in good faith any suggestions made by Parent in connection therewith. The Company shall not (and shall cause its Subsidiaries not to) settle the Rate Cases without the prior written consent of Parent (such consent not to be unreasonably withheld, conditioned or delayed) to the extent that such settlement would result in an outcome for the Company and its Subsidiaries that would be materially adverse to the Company or any of its Subsidiaries, taking into account the requests made by the Company and its Subsidiaries in the proceeding, the resolution of similar recent proceedings by the Company and its Subsidiaries and the reasonable expectations of Parent as of the date hereof for such outcome.

6.6. Access and Reports.

(a) Subject to applicable Law, upon reasonable notice, the Company shall (and shall cause its Subsidiaries to) afford Parent’s officers and other authorized Representatives (including financing sources) reasonable access, during normal business hours throughout the period prior to the Effective Time, to its employees, properties, books, contracts and records and, during such period, the Company shall (and shall cause its Subsidiaries to) furnish promptly to Parent all information concerning its business, properties and personnel as may reasonably be requested, provided that no investigation pursuant to this Section 6.6 shall affect or be deemed to modify any representation or warranty made by the Company herein, and provided, further, that the foregoing shall not require the Company (i) to permit any inspection, or to disclose any information, that in the reasonable judgment of the Company would result in the disclosure of any trade

-41-

secrets of third parties or violate any obligations of the Company or any of its Subsidiaries with respect to confidentiality if the Company shall have used reasonable best efforts to obtain the consent of such third party to such inspection or disclosure or (ii) to disclose any privileged information of the Company or any of its Subsidiaries. All requests for information made pursuant to this Section 6.6 shall be directed to the executive officer or other Person designated by the Company. All such information shall be governed by the terms of the Confidentiality Agreement.

(b) Financing Cooperation. The Company shall, and shall cause its Subsidiaries to, use its and their reasonable best efforts to provide such cooperation as may be reasonably requested by Parent in connection with the financing of the Transactions, including using reasonable best efforts to (i) provide reasonable assistance with the preparation of any discussions of business, financial statements, pro forma financials, projections, management discussion and analysis, and other customary financial data of the Company and its Subsidiaries, all for use in connection therewith and (ii) direct its independent accountants to provide customary and reasonable assistance to Parent including in connection with providing customary comfort letters. Parent shall reimburse the Company for all reasonable out-of-pocket costs or expenses incurred by the Company and its Subsidiaries in connection with cooperation provided for in this Section 6.6(b) to the extent the information requested of the Company was not otherwise prepared or available in the ordinary course of business. For the avoidance of doubt, Parent hereby expressly acknowledges that its obligations under this Agreement are not subject to the availability of any financing.

6.7. Stock Exchange De-listing. Prior to the Closing Date, the Company shall cooperate with Parent and use reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable Laws and rules and policies of the NYSE to enable the delisting by the Surviving Corporation of the Shares from the NYSE and the deregistration of the Shares under the Exchange Act as promptly as practicable after the Effective Time.

6.8. Publicity. The initial press release regarding the Merger shall be a joint press release and thereafter the Company and Parent each shall consult with each other prior to issuing any press releases or otherwise making public announcements with respect to the Merger and the other transactions contemplated by this Agreement and prior to making any filings with any third party and/or any Governmental Entity (including any national securities exchange or interdealer quotation service) with respect thereto, and no public release or announcement concerning the Merger or any other transactions contemplated by this Agreement shall be issued or made by any party without the prior consent of the other parties except as may be required by Law or by obligations pursuant to any listing agreement with or rules of any national securities exchange or interdealer quotation service or by the request of any Governmental Entity (in which case the party required to issue or make such press release or announcement shall give reasonable notice to the other party or parties, including the opportunity to review or comment on such press release or announcement to the extent practicable).

-42-

6.9. Employee Benefits.

(a) Parent agrees that, during the period commencing at the Effective Time and ending two years after the Effective Time (“Benefit Period”), Parent shall provide, or shall cause to be provided (1) to each employee of the Company and its Subsidiaries (other than any employee who is covered by a collective bargaining or similar agreement between the Company and any labor union) who is employed as of immediately prior to the Effective Time and continues employment with the Company or its Subsidiaries immediately after the Effective Time (each, a “Continuing Employee”), base salary, annual incentive opportunity and long-term incentive compensation opportunities, which are, in each case, no less than those provided by the Company and its Subsidiaries immediately prior to the Effective Time to each such Continuing Employee, (2) to the Continuing Employees, pension and welfare benefits and perquisites (to the extent described in the Company Disclosure Letter) that are no less favorable in the aggregate than those provided by the Company and its Subsidiaries immediately prior to the Effective Time and (3) to the Continuing Employees, severance benefits that are no less favorable than the severance benefits provided by the Company and its Subsidiaries to such Continuing Employees immediately prior to the Effective Time.

(b) For purposes of vesting, benefit accrual (but not for benefit accrual purposes under any defined benefit pension plan), vacation and sick time credit and eligibility to participate under the employee benefit plans, programs and policies of Parent and its Subsidiaries providing benefits to any Continuing Employee after the Effective Time (including the Benefit Plans) (the “New Plans”), each Continuing Employee shall be credited with his or her years of service with the Company and its Subsidiaries and their respective predecessors before the Effective Time, to the same extent and for the same purpose as such Continuing Employee was entitled, before the Effective Time, to credit for such service under any similar Benefit Plan in which such Continuing Employee participated or was eligible to participate immediately prior to the Effective Time; provided that the foregoing shall not apply to the extent that its application would result in a duplication of benefits with respect to the same period of service. In addition, and without limiting the generality of the foregoing, Parent shall cause (i) each Continuing Employee to be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan is replacing comparable coverage under a Benefit Plan in which such Continuing Employee participated immediately before the Effective Time (such plans, collectively, the “Old Plans”), and (ii) for purposes of each New Plan providing medical, dental, pharmaceutical and/or vision benefits to any Continuing Employee, any evidence of insurability requirements, all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such Continuing Employee and his or her covered dependents, to the extent such conditions were inapplicable or waived under the comparable Old Plan. Parent shall cause any eligible expenses incurred by any

-43-

Continuing Employee and his or her covered dependents during the portion of the plan year of the Old Plan ending on the date such Continuing Employee’s participation in the corresponding New Plan begins to be taken into account under such New Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such Continuing Employee and his or her covered dependents for the applicable plan year; provided that such amount was taken into account for the same purpose under the similar Benefit Plan for such period and would not result in the duplication of benefits.

(c) Parent hereby acknowledges that a “change in control” or other event with similar import, within the meaning of the Benefit Plans that contain such terms will occur upon the Effective Time. Parent shall, and shall cause the Surviving Corporation and any successor thereto to, honor, assume, fulfill and discharge the Company’s and its Subsidiaries’ obligations under the Company’s Change in Control Severance Plan and the other Benefit Plans listed on Section 6.9(c) of the Company Disclosure Letter. Parent agrees that it will not (nor cause any other Person or entity to) request that the Company or any Continuing Employee waive or relinquish any compensation or benefit entitlement or right (including any severance entitlement) existing as of the Effective Time.

(d) (i) If the Effective Time occurs during calendar year 2014, at the Effective Time the Company shall pay each participant in the Company’s incentive plans (the “Incentive Plans”) who remains employed through the Effective Time, an annual incentive amount in respect of the 2014 fiscal year, equal to the higher of (A) the target level (at 100% funding) and (B) the actual level of performance achieved as of the Effective Time (with such performance measure pro-rated, if applicable, for the portion of the performance cycle completed at the Effective Time), as determined by the compensation committee of the board of directors of the Company prior to the Effective Time in accordance with the terms of the applicable Incentive Plans and based on performance through the day that is no more than five business days prior to the Effective Time.

(ii) If the Effective Time has not occurred by December 31, 2014 (or December 31, 2015), the Company shall (A) determine the amounts earned under the Incentive Plans in respect of the 2014 fiscal year (or 2015 fiscal year), with performance based on either (x) the target level (at 100% funding) or (y) the actual level of performance for the 2014 fiscal year (or 2015 fiscal year), (B) pay such amounts in respect of the 2014 fiscal year (or 2015 fiscal year) no later than the Closing Date and (C) establish annual incentive award targets, maximums and performance award levels and performance measures for the 2015 fiscal year (or 2016 fiscal year) under the Incentive Plans.

-44-

(iii) If the Effective Time occurs during calendar year 2015, the Company shall pay such amounts in respect of the 2015 fiscal year on the Closing Date, with performance determined at the higher of (x) target level (at 100% funding) and (y) the actual level of performance for the 2015 fiscal year achieved as of the Effective Time (with such performance measure pro-rated, if applicable, for the portion of the performance cycle completed at the Effective Time), as determined by the compensation committee of the board of directors of the Company prior to the Effective Time based on performance through the day that is no more than five business days prior to the Effective Time.

(iv) If the Effective Time occurs during calendar year 2016, the Company shall pay such amounts in respect of the 2016 fiscal year on the Closing Date, pro-rated based on the number of calendar days elapsed in the 2016 fiscal year through the Closing Date, with performance determined at the higher of (x) target level (at 100% funding) and (y) the actual level of performance for the 2016 fiscal year achieved as of the Effective Time (with such performance measure pro-rated, if applicable, for the portion of the performance cycle completed at the Effective Time), as determined by the compensation committee of the board of directors of the Company prior to the Effective Time based on performance through the day that is no more than five business days prior to the Effective Time, and Parent shall, and shall cause the Surviving Corporation to, honor and pay incentive award amounts for the remainder of the 2016 fiscal year (with an offset for the pro rata portion previously paid) in accordance with the targets, levels and measures established by the Company prior to the Closing Date and the terms of the applicable Incentive Plans.

(e) After the Effective Time, except as required by Section 304 of the Sarbanes-Oxley Act of 2002, the Company shall have no further rights to seek recovery from employees of amounts paid under the Stock Plans or the Incentive Plans for periods ending on or prior to the Effective Time.

(f) No later than the Effective Time, the Company shall take all actions reasonably necessary to cause each Continuing Employee to become 100% vested in such Continuing Employee’s accounts under each Company 401(k) plan (excluding for the avoidance of doubt any 401(k) plans maintained pursuant to any collective bargaining or similar agreement between the Company and any labor union), effective as of the Closing Date.

(g) With respect to each individual who is employed by the Company or any of its Subsidiaries immediately before the Effective Time whose terms and conditions of employment are governed by a CBA between the Company and any labor union, Parent shall, or shall cause the Surviving Corporation to, continue to honor such CBA, through its expiration, modification or termination in accordance with its terms or applicable Law.

-45-

(h) The provisions of this Section 6.9 are solely for the benefit of the parties to this Agreement, and nothing in this Agreement, whether express or implied, is intended to, or shall, (i) constitute the establishment or adoption of or an amendment to any employee benefit plan for purposes of ERISA or otherwise be treated as an amendment or modification of any Benefit Plan, New Plan or other benefit plan, agreement or arrangement, other than Section 6.9(f), (ii) limit the right of Parent, the Company or their respective Subsidiaries to amend, terminate or otherwise modify any Benefit Plan, New Plan or other benefit plan, agreement or arrangement following the Effective Time, or (iii) create any third-party beneficiary or other right (including, but not limited to, a right to employment) in any Person, including any current or former employee of the Company or any Subsidiary of the Company, any participant in any Benefit Plan, New Plan or other benefit plan, agreement or arrangement (or any dependent or beneficiary thereof).

The Surviving Corporation shall pay all charges and expenses, including those of the Paying Agent, in connection with the transactions contemplated in Article IV, and Parent shall reimburse the Surviving Corporation for such charges and expenses. Except as otherwise provided in Section 8.5, whether or not the Merger is consummated, all costs and expenses incurred in connection with this Agreement and the Merger and the other transactions contemplated by this Agreement shall be paid by the party incurring such expense.

6.11. Indemnification; Directors’ and Officers’ Insurance. (a) From and after the Effective Time, each of Parent and the Surviving Corporation agrees that it will indemnify and hold harmless, to the fullest extent permitted under applicable Law (and Parent shall also advance expenses as incurred to the fullest extent permitted under applicable Law, provided that the Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification), each present and former director and officer of the Company and its Subsidiaries (collectively, the “Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or related to such Indemnified Parties’ service as a director or officer of the Company or its Subsidiaries or services performed by such persons at the request of the Company or its Subsidiaries at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, including the transactions contemplated by this Agreement.

(b) Prior to the Effective Time, the Company shall and, if the Company is unable to, Parent shall cause the Surviving Corporation as of the Effective Time to, obtain and fully pay the premium for the extension of (i) the directors’ and officers’ liability coverage of the Company’s existing directors’ and officers’ insurance policies, and (ii) the Company’s existing fiduciary liability insurance policies, in each case for a claims reporting or discovery period of six years from and after the Effective Time from an insurance carrier with the same or better credit rating as the Company’s insurance carrier as of the date hereof with respect to directors’ and officers’ liability insurance and fiduciary liability insurance (collectively, “D&O Insurance”) with terms, conditions, retentions and limits of liability that are at least as favorable as the

-46-

Company’s existing policies with respect to any actual or alleged error, misstatement, misleading statement, act, omission, neglect, breach of duty or any matter claimed against a director or officer of the Company or any of its Subsidiaries by reason of him or her serving in such capacity that existed or occurred at or prior to the Effective Time (including in connection with this Agreement or the transactions or actions contemplated hereby). If the Company and the Surviving Corporation for any reason fail to obtain such “tail” insurance policies as of the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, continue to maintain in effect for a period of at least six years from and after the Effective Time the D&O Insurance in place as of the date hereof with terms, conditions, retentions and limits of liability that are at least as favorable as provided in the Company’s existing policies as of the date hereof, or the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, use reasonable best efforts to purchase comparable D&O Insurance for such six-year period with terms, conditions, retentions and limits of liability that are at least as favorable as provided in the Company’s existing policies as of the date hereof; provided, however, that in no event shall Parent or the Surviving Corporation be required to expend for such policies pursuant to this sentence an annual premium amount in excess of 300% of the annual premiums paid as of the date hereof by the Company for such insurance; and provided, further, that if the annual premiums of such insurance coverage exceed such amount, the Surviving Corporation shall obtain a policy with the greatest coverage available for a cost not exceeding such amount.

(c) If Parent or the Surviving Corporation or any of their respective successors or assigns shall (i) consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfer all or substantially all of its properties and assets to any individual, corporation or other entity, then, and in each such case, proper provisions shall be made so that the successors and assigns of Parent or the Surviving Corporation shall assume all of the obligations set forth in this Section 6.11.

(d) The provisions of this Section 6.11 are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties.

(e) The rights of the Indemnified Parties under this Section 6.11 shall be in addition to any rights such Indemnified Parties may have under the certificate of incorporation, certificate of formation or bylaws of the Company or any of its Subsidiaries, or under any applicable Contracts or Laws. All rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time and rights to advancement of expenses relating thereto now existing in favor of any Indemnified Party as provided in the certificate of incorporation, certificate of formation or bylaws of the Company or of any Subsidiary of the Company or any indemnification agreement between such Indemnified Party and the Company or any of its Subsidiaries, in each case as in effect on the date of this Agreement, shall survive the Merger and shall not be amended, repealed or otherwise modified in any manner that would adversely affect any right thereunder of any such Indemnified Party.

The Company shall give Parent the opportunity to participate in the defense of any Transaction Litigation, and the Company shall not settle or agree to settle any Transaction Litigation, without Parent’s prior written consent (which consent shall not be unreasonably withheld, delayed or conditioned).

speaks as of an earlier date, in which case such representation and warranty shall be true and correct as of such earlier date), provided, however, that notwithstanding anything herein to the contrary, the condition set forth in this Section 7.2(a)(iv) shall be deemed to have been satisfied even if any such representations and warranties of the Company are not so true and correct unless the failure of such representations and warranties of the Company to be so true and correct, individually or in the aggregate, has had or is reasonably likely to have a Company Material Adverse Effect; and (v) Parent shall have received at the Closing a certificate signed on behalf of the Company by a senior executive officer of the Company to the effect that such officer has read this Section 7.2(a) and the conditions set forth in this Section 7.2(a) have been satisfied.

8.2. Termination by Either Parent or the Company. This Agreement may be terminated and the Merger may be abandoned at any time prior to the Effective Time by action of the board of directors of either Parent or the Company if:

(a) the Merger shall not have been consummated by July 29, 2015 whether such date is before or after the date of adoption of this Agreement by the stockholders of the Company referred to in Section 7.1(a) (the “Termination Date”); provided, however, that if on July 29, 2015 (i) the condition set forth in Section 7.1(b) is not satisfied but all of the other conditions to Closing shall have been satisfied or waived (other than Section 7.2(c) or those conditions that by their nature are to be satisfied at the Closing) and the condition set forth in Section 7.1(b) remains capable of being satisfied and (ii) no final and non-appealable order or any Merger Law imposed by any Governmental Entity shall be in effect as of such date of determination that constitutes a Burdensome Condition, then the Termination Date may be extended until October 29, 2015 at the election of Parent or the Company by written notice to the other party (and such date shall then be the “Termination Date”).

(c) any Order permanently restraining, enjoining or otherwise prohibiting or making illegal the consummation of the Merger shall have become final and non-appealable (whether before or after the adoption of this Agreement by the stockholders of the Company referred to in Section 7.1(a)); provided, however, that the right to terminate this Agreement pursuant to this Section 8.2(c) shall not be available to any party whose failure to comply with any provision of this Agreement has been the cause of, or materially contributed to, either the imposition of such Order or the failure of such Order to be resisted, resolved, lifted or vacated, as applicable.

-51-

8.5. Effect of Termination and Abandonment.

(a) Except as provided in paragraphs (b), (c), (d) and (e) below, in the event of termination of this Agreement and the abandonment of the Merger pursuant to this Article VIII, this Agreement shall become void and of no effect with no liability to any Person on the part of any party hereto (or of any of its Representatives or Affiliates); provided, however, and notwithstanding anything in the foregoing to the contrary, that (i) except as otherwise provided herein, no such termination shall relieve any party hereto of any liability or damages to the other party hereto resulting from any willful or intentional material breach of this Agreement and (ii) the provisions set forth in this Section 8.5 and Section 9.1 shall survive the termination of this Agreement.

-52-

(b) In the event that:

(i) a bona fide Acquisition Proposal shall have been made or any Person shall have made or publicly announced or otherwise communicated to the Company, the board of directors of the Company or any Representatives of the Company an intention (whether or not conditional) to make an Acquisition Proposal with respect to the Company or any of its Subsidiaries (and such Acquisition Proposal or publicly announced intention shall not have been publicly withdrawn without qualification (A) no more than 75 days following the date such Acquisition Proposal has been made, with respect to any termination pursuant to Section 8.2(a), and (B) no fewer than five business days prior to, with respect to termination pursuant to Section 8.2(b), the date of the Stockholders Meeting) and thereafter this Agreement is terminated by either Parent or the Company pursuant to Section 8.2(a), 8.2(b) or 8.4(b);

(ii) this Agreement is terminated by Parent pursuant to Section 8.4(a); or

As used herein, “Termination Fee” shall mean a cash amount equal to (x) $259,000,000 or (y) $293,000,000 plus Parent Expenses if (i) the Company terminates this Agreement pursuant to Section 8.3(a) to enter into an Alternative Acquisition Agreement from a Bidding Party, (ii) Parent terminates this Agreement pursuant to Section 8.4(a) and the action by the board of directors of the Company that gave rise to Parent’s termination under Section 8.4(a) was the result of an Acquisition Proposal by a Bidding Party or (iii) the Termination Fee becomes payable in accordance with Section 8.5(b)(i) and a Bidding Party made the Acquisition Proposal referred to in Section 8.5(b)(i) or the Acquisition Proposal referred to in Section 8.5(b)(i)(A). “Bidding Party” means any Person or group of Persons, or any of their respective controlled Affiliates, who has made an Acquisition Proposal on or after April 1, 2014 and prior to the date hereof. Notwithstanding anything

-53-

to the contrary in this Agreement, the parties hereby acknowledge that in the event that the Termination Fee (together with the Parent Expenses) is paid by the Company pursuant to this Section 8.5(b), the Termination Fee (together with the Parent Expenses) shall be Parent’s and Merger Sub’s sole and exclusive remedy for monetary damages under this Agreement.

(c) If (i) the Company or Parent terminates this Agreement pursuant to Section 8.2(a) or 8.2(c) or (ii) the Company terminates this Agreement pursuant to Section 8.3(b) because of a failure by Parent to comply with its obligations under Section 6.5(d) or Section 6.5(e), and, in each of (i) and (ii), at the time of such termination, any of the conditions set forth in Sections 7.1(b), 7.1(c) or 7.2(c) shall not have been satisfied, and in addition, in the case of a termination under Section 8.2(c), at the time of termination a Governmental Entity shall have enacted such Order with respect to the Regulatory Approvals, and in each of (i) and (ii), at the time of such termination, all other conditions to the Closing set forth in Sections 7.1 and 7.2 shall have been satisfied or waived (other than those conditions that by their terms are to be satisfied at the Closing but which conditions would be satisfied or would be capable of being satisfied if the Closing Date were the date of such termination, or those conditions that have not been satisfied as a result of a breach by Parent) (each of (i) and (ii), a “Regulatory Termination”), then (A) Parent shall pay Company a termination fee equal to the Nonvoting Preferred Stock Purchase Price (the “Parent Termination Fee”) which Parent Termination Fee shall be paid by Parent by means of the Company redeeming, as of the time of such termination, all of the outstanding shares of Nonvoting Preferred Stock for $0.01 per share, and all of the outstanding shares of Nonvoting Preferred Stock will no longer be outstanding as of the time of such redemption, and (B) Parent shall promptly, but in no event later than five days after being notified of such by the Company, pay all of the documented out-of-pocket expenses incurred by the Company in connection with this Agreement and the transactions contemplated by this Agreement, up to a maximum amount of $40,000,000, payable by wire transfer of immediately available funds. Notwithstanding anything to the contrary in this Agreement, the parties hereby acknowledge that in the event that the Parent Termination Fee (together with the expense reimbursement contemplated by the immediately preceding sentence) is paid by Parent pursuant to this Section 8.5(c), the Parent Termination Fee (together with the expense reimbursement contemplated by the immediately preceding sentence) shall be the Company’s sole and exclusive remedy for monetary damages under this Agreement, unless at the time of such termination Parent is in breach of its obligations under Section 6.5; provided, that the Company is not then in breach of Section 6.5.

(d) In the event this Agreement is terminated by the Company or Parent pursuant to this Article VIII other than pursuant to a Regulatory Termination, the Company will redeem, within five business days of such termination, all of the outstanding shares of Nonvoting Preferred Stock for an aggregate amount equal to the Nonvoting Preferred Stock Purchase Price, payable by the Company to Parent by wire transfer of immediately available funds, and all of the outstanding shares of Nonvoting Preferred Stock will no longer be outstanding as of the time of such redemption.

-54-

(e) In the event that this Agreement is terminated either (x) by Parent or the Company pursuant to Section 8.2(b) or (y) in the case of termination of this Agreement of the type contemplated by Section 8.5(b)(i) other than (i) pursuant to Section 8.2(a) and the Parent Termination Fee is payable or (ii) pursuant to Section 8.4(b) and (B) the Termination Fee is not then payable pursuant to Section 8.5(b), the Company shall promptly, but in no event later than five days after being notified of such by Parent, pay all of the documented out-of-pocket expenses incurred by Parent or Merger Sub in connection with this Agreement and the transactions contemplated by this Agreement up to a maximum amount of $40,000,000, payable by wire transfer of immediately available funds (“Parent Expenses”); provided, that the payment by the Company of Parent Expenses pursuant to this Section 8.5(e) shall be credited against any amount that may become payable pursuant to clause (x) of the definition of Termination Fee. The existence of circumstances which could require the Termination Fee to become subsequently payable by the Company pursuant to Section 8.5 shall not relieve the Company of its obligations to pay the Parent Expenses pursuant to this Section 8.5(e). The payment by the Company of Parent Expenses pursuant to this Section 8.5(e) shall not relieve the Company of any subsequent obligation to pay the Termination Fee pursuant to Section 8.5(b) (less a credit in the amount of Parent Expenses, if applicable).

(f) The parties acknowledge that the agreements contained in this Section 8.5 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the parties would not enter into this Agreement; accordingly, if the Company fails to promptly pay the amounts due pursuant to Section 8.5(b) or Section 8.5(d), or Parent fails to promptly pay the amount due pursuant to Section 8.5(c), and, in order to obtain such payment, Parent or Merger Sub, on the one hand, or the Company, on the other hand, commences a suit that results in a judgment against the Company for the amounts set forth in Section 8.5(b) or Section 8.5(d), or any portion thereof, or a judgment against Parent for the amount set forth in Section 8.5(c) or any portion thereof, the Company shall pay to Parent or Merger Sub, on the one hand, or Parent shall pay to the Company, on the other hand, its costs and expenses (including attorneys’ fees) in connection with such suit, together with interest on the amount of such amount or portion thereof at the Interest Rate in effect on the date such payment was required to be made through the date of payment.

It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the Court of Chancery of the State of Delaware, this being in addition to any other remedy to which such party is entitled at law or in equity.

Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance with Section 9.3 without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, Persons other than the parties hereto may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.
