EFFECT OF THE MERGER ON CAPITAL STOCK

2.1. 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 Merger Sub:

(a) Merger Consideration. Each share of Class B common stock, par value $0.01 per share, of the Company (each, a “Class B Share”), issued and outstanding immediately prior to the Effective Time (other than (x) Dissenting Shares and (y) any Class B Shares held in treasury by the Company or held by any direct or indirect Subsidiary of the Company, Parent or

- 2 -

Merger Sub (each such Class B Share described in this clause (y), an “Excluded Share”) (each such Class B Share not constituting an Excluded Share or Dissenting Share, an “Outstanding Share”)) shall be converted into the right to receive an amount in cash, without interest, equal to the Merger Consideration. At the Effective Time, all of the Class B Shares converted into the right to receive the Merger Consideration shall cease to be outstanding, shall be automatically cancelled and retired and shall cease to exist, and each certificate (a “Certificate”) that immediately prior to the Effective Time represented any of the Class B Shares (other than Excluded Shares and Dissenting Shares) shall thereafter represent only the right to receive the Merger Consideration to be paid in consideration therefor upon surrender of such Certificate in accordance with this Article 2. For purposes of this Agreement, (i) “Merger Consideration” shall mean the quotient of (A) (1) $652,000,000, plus (2) the Working Capital Surplus, if any, minus (3) the Working Capital Shortfall, if any, divided by (B) (1) the number of outstanding Class B Shares as of immediately prior to the Effective Time (other than Excluded Shares, but including, for the avoidance of doubt, Dissenting Shares), plus (2) the number of RSUs as of immediately prior to the Effective Time; (ii) “Working Capital Shortfall” means the positive difference, if any, between (A) the Target Working Capital, minus (B) the Closing Date Working Capital Estimate; and (iii) “Working Capital Surplus” means the positive difference, if any, between (A) the Closing Date Working Capital Estimate, minus (B) the Target Working Capital.

(b) Cancellation of 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 and retired without payment of any consideration therefor and shall cease to exist. The one outstanding share of Series A Preferred Stock shall remain issued and outstanding and unaffected by the Merger.

(c) Merger Sub. At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, 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 fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

2.2. Payment of Cash for Class B Shares and RSUs.

(a) Disbursing Agent. Prior to the Closing Date, Parent shall designate a bank or trust company that is reasonably satisfactory to the Company to serve as the disbursing agent for the Merger Consideration and payments in respect of the RSUs (the “Disbursing Agent”). Prior to the filing of the Certificate of Merger with the Secretary of State of the State of Delaware, Parent will deposit, or will cause to be deposited, with the Disbursing Agent cash in the aggregate amount sufficient to pay (i) the Closing Merger Consideration in respect of all Class B Shares outstanding immediately prior to the Effective Time (except as provided in Section 2.4) and (ii) any cash necessary to pay the Closing Merger Consideration in respect of the RSUs outstanding immediately prior to the Effective Time (such cash referred to in subsections (a)(i) and (a)(ii) being hereinafter referred to as the “Exchange Fund”). Pending distribution of the cash deposited with the Disbursing Agent, such cash shall be held in trust for the benefit of the holders of Class B Shares and RSUs outstanding immediately prior to the Effective Time and shall not be used for any other purposes; provided, however, that Parent may direct the Disbursing Agent to invest such cash in (i) obligations of or guaranteed by the United

- 3 -

States of America or any agency or instrumentality thereof, (ii) money market accounts, certificates of deposit, bank repurchase agreements or banker’s acceptances of, or demand deposits with, commercial banks having a combined capital and surplus of at least $500,000,000, or (iii) commercial paper obligations rated P-1 or A-1 or better by Standard & Poor’s Corporation or ▇▇▇▇▇’▇ Investor Services, Inc. Any profit or loss resulting from, or interest and other income produced by, such investments shall be for the account of Parent. For purposes of this Agreement, “Closing Merger Consideration” shall mean the quotient of (A) (i) $652,000,000, plus (ii) the Working Capital Surplus, if any, minus (iii) the Working Capital Shortfall, if any, minus (iv) the Reconciliation Deposit, divided by (B) (i) the number of outstanding Class B Shares as of immediately prior to the Effective Time (other than Excluded Shares, but including, for the avoidance of doubt, Dissenting Shares), plus (ii) the number of RSUs as of immediately prior to the Effective Time.

(b) Payment Procedures.

(i) As promptly as practicable after the Effective Time, the Surviving Corporation shall send, or cause the Disbursing Agent to send, to each record holder of Class B Shares as of immediately prior to the Effective Time a letter of transmittal and instructions for exchanging their Class B Shares for the Closing Merger Consideration payable therefor. The letter of transmittal will be in customary form and will specify that delivery of Certificates will be effected, and risk of loss and title will pass, only upon delivery of the Certificates to the Disbursing Agent. Upon surrender of such Certificate(s) to the Disbursing Agent together with a properly completed and duly executed letter of transmittal and any other documentation that the Disbursing Agent may reasonably require, the record holder thereof shall be entitled to receive the Merger Consideration payable in exchange therefor, without interest. Until so surrendered and exchanged, each such Certificate shall, after the Effective Time, be deemed to represent only the right to receive the Merger Consideration in respect of such Certificate, and until such surrender and exchange, no cash shall be paid to the holder of such outstanding Certificate in respect thereof.

(ii) If payment is to be made to 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 (a “Person”) other than the registered holder of the Class B Shares formerly represented by the Certificate(s) surrendered in exchange therefor, it shall be a condition to such payment that the Certificate(s) so surrendered shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such payment shall pay to the Disbursing Agent any applicable stock transfer taxes required as a result of such payment to a Person other than the registered holder of such Class B Shares or establish to the satisfaction of the Disbursing Agent that such stock transfer taxes have been paid or are not payable.

(c) Stock Transfer Books. After the Effective Time, there shall be no further transfers on the stock transfer books of the Company of the Class B Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation, Parent or the Disbursing Agent, such shares shall be canceled and exchanged for the consideration provided for, and in accordance with the procedures set forth, in this Article 2.

- 4 -

(d) Termination of the Exchange Fund. If any cash deposited with the Disbursing Agent remains unclaimed twelve months after the Effective Time, such cash shall be returned to Parent or the Surviving Corporation upon demand, and any holder who has not surrendered such holder’s Certificate(s) for the Closing Merger Consideration payable in respect thereof prior to that time shall thereafter look only to the Surviving Corporation for payment of the Merger Consideration. Notwithstanding the foregoing, none of Parent, Merger Sub, the Company, the Surviving Corporation, the Disbursing Agent or any of their respective directors, officers, employees and agents shall be liable to any holder of Certificates for an amount paid to a public official pursuant to any applicable unclaimed property laws. Any amounts remaining unclaimed by holders of Certificates as of the date on which such amounts would otherwise escheat to or become property of any Governmental Entity shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation on such date, free and clear of any claims or interest of any Person previously entitled thereto.

(e) Lost, Stolen or Destroyed Certificates. In the event that any Certificate has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed, in addition to the posting by such holder of any bond in such reasonable amount as the Surviving Corporation or the Disbursing Agent may direct as indemnity against any claim that may be made against the Surviving Corporation or the Disbursing Agent with respect to such Certificate, the Disbursing Agent will issue in exchange for such lost, stolen or destroyed Certificate the Closing Merger Consideration in respect thereof entitled to be received pursuant to this Agreement.

(f) Withholding Rights. Parent, the Surviving Corporation and the Disbursing Agent shall be entitled to deduct and withhold from the consideration otherwise payable to a holder of Class B Shares or RSUs pursuant to this Agreement any amounts required to be deducted and withheld with respect to the making of such payment under any applicable Tax Law. To the extent any amounts are so deducted and withheld under the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated under the Code, or any provision of state, local or foreign tax law, any amounts so deducted and withheld will be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

2.3. Treatment of Restricted Stock Units. As of the Effective Time, each RSU granted by the Company that is outstanding immediately prior to the Effective Time will be cancelled and extinguished as of the Effective Time, and the holder thereof will be entitled to receive from Parent and Merger Sub an amount in cash equal to the Merger Consideration without interest in the manner and at the times contemplated by this Agreement.

2.4. Dissenting Shares.

(a) Notwithstanding anything herein to the contrary, Class B Shares held by a holder who has properly demanded in writing appraisal for such Class B Shares in accordance with Section 262 (or any successor provision) of the DGCL (any such shares being referred to as “Dissenting Shares” until such time as such holder fails to perfect or otherwise loses or withdraws such holder’s appraisal rights under the DGCL with respect to such shares) shall not be converted into or represent the right to receive the applicable Merger Consideration specified

- 5 -

in Section 2.1(a) or cash in lieu of fractional shares thereof or any dividends or other distributions but shall be entitled only to such rights as are granted by the DGCL to a holder of Dissenting Shares unless and until such shares cease to be Dissenting Shares.

(b) If any Dissenting Shares shall lose their status as such (through failure to perfect or otherwise), then, as of the later of the Effective Time or the date of loss of such status, such shares shall be thereupon be treated as though such shares had been converted into the Merger Consideration pursuant to Section 2.1(a) as of the Closing Date.

(c) Prior to the Effective Time, the Company shall give Parent prompt notice (and a copy thereof) of any written demand for appraisal, for payment or of objection to the Merger received by the Company prior to the Effective Time pursuant to the DGCL, any written withdrawal of any such demand and any other written demand, notice or instrument delivered to the Company prior to the Effective Time that relates to such a demand. The Company shall keep Parent reasonably informed with respect to all negotiations and proceedings with respect to any such demand and shall give Parent the opportunity to participate in all negotiations and proceedings with respect to any such demands. The Company shall not make any payment with respect to, or settle, offer to settle or otherwise negotiate, any such demands, in each such case without the prior written consent of Parent (such consent not to be unreasonably withheld) or unless required by any Law.

2.5. Adjustments to Prevent Dilution. In the event that, as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, subdivision, issuer tender or exchange offer, or other similar transaction, the Company changes the number of Class B Shares prior to the Effective Time, the Merger Consideration shall be equitably adjusted.

2.6. Net Working Capital; Tax Gross Up Payments.

(a) Closing Determination. (i) Not more than seven (7) Business Days nor less than three (3) Business Days before the Closing Date, the Company shall, in good faith using then available financial information for the Company, prepare and deliver to Parent a separate report (the “Estimated Closing Balance Sheet”) setting forth an estimate of the Adjusted Working Capital as of the Effective Time on the Closing Date (the “Closing Date Working Capital Estimate”) and the calculation thereof, which amount shall be based on the estimated Current Assets and the estimated Current Liabilities as set forth on the Estimated Closing Balance Sheet. The Estimated Closing Balance Sheet shall be prepared in accordance with GAAP, consistently applied, and in accordance with the definition of “Adjusted Working Capital” and the parameters set forth in Section 2.6(a) of the Company Disclosure Letter. If (A) the Closing Date Working Capital Estimate exceeds the Target Working Capital, the aggregate Merger Consideration shall be increased on a dollar-for-dollar basis at Closing by the amount of such excess and (B) the Closing Date Working Capital Estimate is less than the Target Working Capital, the aggregate Merger Consideration shall be reduced on a dollar-for-dollar basis at Closing by the amount of such deficiency, with such increase or reduction to be allocated to Holders in with such Holder’s Pro Rata Share.

- 6 -

(ii) Not more than seven (7) Business Days nor less than three (3) Business Days before the Closing Date, the Company’s outside auditors shall calculate and determine the amount of Severance Benefits Gross-Up Payments, Designated Tax Gross Up Payments and Excess Tax Gross Up Payments (and shall perform all such calculations and make all such determinations required in order to calculate and determine the amounts of Severance Benefits Gross-Up Payments, Designated Tax Gross Up Payments and Excess Tax Gross-Up Payments) in consultation with the Company and Parent, and shall take into account such information and analysis as the Company and Parent may provide. The determination of the amounts of Severance Benefits Gross-Up Payments, Designated Tax Gross Up Payments and Excess Tax Gross-Up Payments shall be made in accordance with Section 280G of the Code and the regulations thereunder and all present value calculations shall be made using the discount rates and methodology used for calculating present values under Section 280G of the Code. For purposes of this Agreement: (A) “Excess Tax Gross-Up Payments” means (1) the total present value (as of the Effective Time) of all “Tax Gross-Up Payments” (within the meaning of the Employment Agreements) that will be paid or are reasonably expected to be paid pursuant to the terms of the Employment Agreements, minus (2) the sum of (i) the lesser of (aa) the sum of all Designated Tax Gross-Up Payments with respect to individuals receiving Designated CIC Payments or (bb) $8,000,000; and (ii) the sum of all Severance Benefit Gross-Up Payments; (B) “Designated Tax Gross-Up Payments” means, with respect to any individual receiving a Designated CIC Payment, the total amount of the Tax Gross-Up Payments (within the meaning of the Employment Agreements) to be paid or reasonably expected to be paid, that is allocable to the individual’s Designated CIC Payment, with such allocable amount being determined based on the ratio of such Designated CIC Payment to the total present value (as of the Effective Time) of all “parachute payments” (within the meaning of Section 280G of the Code) to be made, or reasonably expected to be made, with respect to such individual in connection with the transactions contemplated by this Agreement; (C) “Severance Benefit Gross-Up Payments” means, with respect to any individual receiving Severance Benefits, the total amount of the Tax Gross-Up Payments (within the meaning of the Employment Agreements) to be paid or reasonably expected to be paid, that is allocable to the individual’s Severance Benefits, with such allocable amount being determined based on the ratio of such Severance Benefits to the total present value (as of the Effective Time) of all “parachute payments” (within the meaning of Section 280G of the Code) to be made, or reasonably expected to be made, with respect to such individual in connection with the transactions contemplated by this Agreement; (D) “Severance Benefits” means, the payments provided by reason of a termination without Cause or a termination by the Executive for Good Reason (each within the meaning of the Employment Agreements) (other than a termination without Cause directed before the Effective Time by the Company or a termination by the Executive for Good Reason based on grounds created by the Company before the Effective Time) under the Employment Agreement Severance Provisions; (E) “Employment Agreement Severance Provisions” means, (1) in the case of ▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ ▇▇., Section 5(b) of the Employment Agreements and (2) in the case of ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, Sections 6(a) and 6(b) of the Employment Agreements; and (F) “Employment Agreements” means, those Amended and Restated Executive Employment Agreements referenced in Section 2.6(f)(ii) of the Company Disclosure Letter.

(b) At the Effective Time, Parent shall withhold, from the amounts otherwise payable pursuant to Section 2.1(a), and deposit into a reconciliation fund (the “Reconciliation

- 7 -

Fund”) with an escrow agent mutually acceptable to Parent and the Company (the “Escrow Agent”) on behalf of the holders of Outstanding Shares and the holders of RSU’s (together, the “Holders“), an amount equal to $15,000,000 (the “Reconciliation Deposit”). The Reconciliation Fund shall be governed by the terms set forth in a reconciliation agreement in substantially the form attached hereto as Exhibit D (the “Reconciliation Agreement”) and the disposition of the Reconciliation Fund will be governed by the terms of this Agreement and the Reconciliation Agreement. Each Holder will be entitled to receive such Holder’s Pro Rata Share of any amounts that are released from the Reconciliation Fund to the Holders in accordance with the terms of this Agreement and the Reconciliation Agreement. “Pro Rata Share” means, with respect to each Holder, a fraction the numerator of which is the Merger Consideration to which such Holder is entitled under Section 2.1(a) or Section 2.3, and the denominator of which is the aggregate Merger Consideration.

(c) Post-Closing Determination. Within sixty (60) calendar days after the Closing Date, the Company’s outside auditors as of the Closing Date and the Stockholder Representative shall prepare and deliver to Parent an audited combined consolidated statement of Adjusted Working Capital as of the Effective Time on the Closing Date (the “Closing Balance Sheet”). The Closing Balance Sheet shall be prepared in accordance with GAAP, consistently applied, and in accordance with the definition of “Adjusted Working Capital” and the parameters set forth in Section 2.6(a) of the Company Disclosure Letter. Parent shall provide the Company’s outside auditors, the Stockholder Representative and his representatives reasonable access to the books and records and employees of the Company to the extent necessary for the preparation of the Closing Balance Sheet and shall cause the employees of the Company to cooperate with the Company’s outside auditors, the Stockholder Representative and his representative in connection with his preparation of the Closing Balance Sheet. Not later than thirty (30) calendar days following the date of receipt of the Closing Balance Sheet, Parent shall provide the Stockholder Representative with a notice (a “Dispute Notice”) listing those items, if any, to which Parent takes exception, which notice shall also (i) specifically identify, and provide a reasonably detailed explanation of (1) any deviation that Parent believes to exist between the methodology used to calculate the Closing Date Working Capital Estimate and the methodology used to calculate the Adjusted Working Capital as set forth in the Closing Balance Sheet and (2) any other basis upon which Parent has delivered such list, (ii) set forth the amount of Adjusted Working Capital that Parent has calculated based on the information contained in the Closing Balance Sheet and (iii) specifically identify Parent’s proposed adjustment(s) (the “Proposed Adjustments”). If Parent fails to deliver to the Stockholder Representative the Dispute Notice within thirty (30) calendar days following the date of receipt of the Closing Balance Sheet, Parent shall be deemed to have accepted the Closing Balance Sheet for the purpose of any purchase price adjustment under Section 2.6(d) hereof. Any items not disputed in the Dispute Notice shall be deemed to be accepted and agreed to by the Parent. If the Stockholder Representative does not give Parent notice of objections within thirty (30) calendar days following the date of receipt of the Dispute Notice, the Stockholder Representative shall be deemed to have accepted on behalf of the Holders the Proposed Adjustments for the purpose of any purchase price adjustment under Section 2.6(d) hereof. Any items not disputed shall be deemed to be accepted and agreed by the Stockholder Representative. If Stockholder Representative gives Parent notice of objections to the Proposed Adjustments, and if Parent and the Stockholder Representative are unable, within fifteen (15) calendar days after the date of receipt by Parent of the notice by the Stockholder Representative of objections, to resolve the

- 8 -

disputed exceptions, such disputed exceptions will be referred to an accounting firm jointly selected by Parent and the Stockholder Representative) (the “Independent Accounting Firm”). The Independent Accounting Firm shall, within thirty (30) calendar days following the date of its selection, deliver to Parent and the Stockholder Representative a written report determining such disputed exceptions, and its determinations will be final, conclusive and binding upon Parent and each of the Holders for the purposes of any purchase price adjustment under Section 2.6(d) hereof. The fees and disbursements of the Independent Accounting Firm shall be paid by Parent in the same proportion that the aggregate amount of such remaining disputed items so submitted to the Independent Accounting Firm that is unsuccessfully disputed by Parent (as finally determined by the Independent Accounting Firm) bears to the total amount of such remaining disputed items so submitted, and the balance shall be allocated equally to the Holders.

(d) Post-Closing Adjustment. The aggregate Merger Consideration shall be increased or decreased, as the case may be, on a dollar-for-dollar basis by an amount equal to the difference between the Closing Date Working Capital Estimate and the Adjusted Working Capital as determined in accordance with Section 2.6(c) above. If the Adjusted Working Capital exceeds the Closing Date Working Capital Estimate, the aggregate Merger Consideration shall be increased on a dollar-for-dollar basis by the amount of such excess and Parent shall pay such excess to the Holders in accordance with the terms of Section 2.6(e) below. If the Adjusted Working Capital is less than the Closing Date Working Capital Estimate, the aggregate Merger Consideration shall be reduced on a dollar-for-dollar basis by the amount of such deficiency and such deficiency shall be paid to Parent from the Reconciliation Amount. Within five (5) business days of the completion of any adjustments to the Reconciliation Fund contemplated in this Section 2.6(d), the Escrow Agent shall distribute to each Holder such Holder’s Pro Rata Share of any amounts that are remaining in the Reconciliation Fund in accordance with the terms of this Agreement and the Reconciliation Agreement.

- 35 -

discussions or negotiations with any Person who has made an unsolicited bona fide written Acquisition Proposal regarding such Acquisition Proposal if the Board of Governors of the Company receives from such Person an executed confidentiality agreement containing terms and provisions at least as restrictive as those contained in the Confidentiality Agreement; if and only to the extent that: (x) prior to taking any of the actions set forth in clauses (A) and (B) above, (a) the Board of Governors of the Company shall have determined in good faith (after consultation with its financial advisors and outside legal counsel) that such Acquisition Proposal constitutes or is reasonably likely to result in a Superior Proposal from the Person that has made the applicable Acquisition Proposal and (b) the Board of Governors, after consultation with its outside legal counsel, shall have determined in good faith that the failure to take such action would result in a breach of its fiduciary duties under applicable Law; and (y) such Acquisition Proposal has not been solicited after the date hereof in violation of this Section 5.2 and was made after the date hereof and did not otherwise result from or arise out of a breach of this Section 5.2.

The term “Superior Proposal” shall mean a bona fide written Acquisition Proposal with respect to the Company and its Subsidiaries taken as a whole by a third party, not resulting from or arising out of a breach of this Section 5.2, that is fully-financed or not subject to any financing conditions or contingencies, is not subject to any due diligence condition, is reasonably capable of being consummated on the terms proposed, taking into account all legal, financial, regulatory, timing and similar aspects of, and conditions to, the proposal, and the Person making the proposal, and, if consummated, would result in a transaction more favorable to the Company’s stockholders (in their capacity as stockholders) from a financial point of view than the transactions contemplated by this Agreement, taking into account all the terms and conditions of such proposal and this Agreement (including any changes to the terms of this Agreement offered by Parent in response to a Notice of Superior Proposal or otherwise pursuant to Section 5.2(b)); providing that for purposes of the definition of Superior Proposal, the term Acquisition Proposal shall have the meaning assigned above, except that references to “20%” shall be deemed to be references to “80%.”

Notwithstanding anything in this Section 5.2 to the contrary, prior to obtaining the Company Requisite Vote, the Board of Governors of the Company may, in response to an Acquisition Proposal, withdraw, amend or modify the Governors’ Recommendation in a manner adverse to Parent, recommend or publicly propose to recommend an Acquisition Proposal and/or terminate this Agreement (subject to Section 7.3) in order to accept an Acquisition Proposal, if and only if (1) the Board of Governors of the Company

- 36 -

determines in good faith, after consultation with its outside financial advisors and legal counsel, that (x) such Acquisition Proposal constitutes a Superior Proposal and (y) the failure to take such actions would result in a breach of its fiduciary duties under applicable Law, and (2) the Company has complied in all material respects with this Section 5.2; provided however that the Board of Governors may not take such action until after the fifth business day following the receipt by Parent of written notice from the Company (a “Notice of Superior Proposal”) advising Parent of the Company’s intent to withdraw, amend or modify the Governors’ Recommendation or recommend or propose to recommend an Acquisition Proposal to the Company’s stockholders or terminate this Agreement, that the Board of Governors of the Company has received a Superior Proposal, specifying the material terms and conditions of the Superior Proposal and identifying the Person making such Superior Proposal. The Company agrees that (i) during the five business day period after receipt by Parent of a Notice of Superior Proposal, the Company and its Representatives shall negotiate in good faith with Parent and its Representatives regarding any revisions to the terms of the transaction contemplated by this Agreement proposed by Parent and (ii) the Company may take any such action with respect to an Acquisition Proposal that was a Superior Proposal only if such Acquisition Proposal continues to be a Superior Proposal in light of any revisions to the terms of the transaction contemplated by this Agreement to which Parent shall have agreed prior to the expiration of such five business day period. The Company agrees that it will deliver to Parent a new Notice of Superior Proposal with respect to each Acquisition Proposal that has been materially revised or modified prior to taking any action pursuant to the second sentence of this Section 5.2(b) and that a new five business day period shall commence, for purposes of this Section 5.2(b), with respect to each such materially revised or modified Acquisition Proposal from the time Parent receives a Notice of Superior Proposal with respect thereto. For purposes of this Section 5.2(b), the only days that shall not be considered “business days” shall be Saturdays, Sundays and Thanksgiving Day (November 22, 2007).

(c) The Company shall, and shall direct each of its Representatives to, immediately cease any existing solicitations, discussions or negotiations with any Person (other than the parties hereto) that has made or indicated an intention to make an Acquisition Proposal.

(d) The Company agrees that it will notify Parent as promptly as practicable (and, in any event, within 24 hours) if any inquiries, proposals or offers with respect to any Acquisition Proposal or potential Acquisition Proposal are received by, any such information is requested from, or any such discussions or negotiations are sought to be initiated or continued with, it or any of its Representatives, indicating, in connection with such notice, the name of such Person and the material terms and conditions of any proposal or offer and thereafter shall keep Parent informed, on a current basis, on the status and terms of any such proposal or offer and the status of any such discussions or negotiations.

- 37 -

reasonable best efforts to obtain the Written Consent and notwithstanding anything contained in this Agreement, (i) in the event that subsequent to the date of this Agreement the Board of Governors of the Company determines in good faith after consultation with its outside legal counsel that its fiduciary duties under applicable Laws require it to withdraw, modify or amend the Governors’ Recommendation in any manner, the Board of Governors of the Company may, prior to the receipt of the Written Consent, so withdraw, modify or amend the Governors’ Recommendation and (ii) notwithstanding the foregoing (or Section 5.2(b)), the Company shall, subject to the provisions of this Section 5.3, submit this Agreement to the holders of Shares for adoption by the Written Consent and shall use its best efforts to do so within the time period prescribed herein. As promptly as practicable, but no more than 20 calendar days, after receipt of sufficient executed Written Consents to approve this Agreement and the Merger, the Company shall deliver, pursuant to Section 228 of the DGCL (and in accordance with applicable law), a written notice to all stockholders of the Company that did not execute the Written Consent informing them that this Agreement and the Merger were adopted and approved by the stockholders of the Company. As promptly as practicable, but no later than the earlier of (i) the 20^th calendar day following the transfer of 14% of the interests of the defendants pursuant to the litigation pending against the Company captioned ▇▇▇▇▇▇▇▇ v.

Without limiting the generality of the foregoing, the Company and Parent shall make the filings required pursuant to the HSR Act within 10 business days of the date of execution of this Agreement. 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 the other on, 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

- 43 -

investigative (an “Action”), arising out of, relating to or in connection with any action or omission occurring or alleged to have occurred before the Closing (including acts or omissions in connection with such persons serving as an officer, governor, director or other fiduciary in any entity if such service was at the request or for the benefit of the Company or its Subsidiaries) or the transactions contemplated by this Agreement.

Alternatively, the Company will purchase, if requested by Parent, a six-year “tail” prepaid policy prior to the Effective Time on terms and conditions no less advantageous to the Indemnified Parties than the existing directors’ and officers’ liability insurance maintained by the Company and, if such “tail” prepaid policy has been obtained by the Company prior to the Closing, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, maintain such policy in full force and effect, for its full term, and continue to honor their respective obligations thereunder, and all other obligations under this Section 5.9(c) shall terminate.

(d) The obligations of Parent and the Surviving Corporation under this Section 5.9 shall not be terminated or modified by such parties in a manner so as to adversely affect any Indemnified Party to whom this Section 5.9 applies without the consent of such affected Indemnified Party. If Parent or the Surviving Corporation or any of their respective successors or assigns (i) shall 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) shall 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, as the case may be, shall assume all of the obligations set forth in this Section.

(e) The provisions of this Section 5.9 are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties and their heirs and legal representatives.

This Agreement (including any exhibits and annexes hereto), the Company Disclosure Letter, the Parent Disclosure Letter and the Non-Disclosure Agreement, dated September 13, 2007, between Parent and the Company (the “Confidentiality Agreement”) constitute the entire agreement, and supersede all other prior agreements, understandings, representations and warranties both written and oral, among the parties, with respect to the subject matter hereof. The parties acknowledge that in order to secure financing for the Merger, Parent, Merger Sub and/or their Affiliates may enter into one or more bank commitment letters which will contain provisions regarding the preparation of an information memorandum that contains information regarding the Merger and the Company. Notwithstanding any provision of this Agreement or the Confidentiality Agreement to the contrary, the Company agrees that Parent, Merger Sub and their agents may disclose, on a confidential basis, confidential information regarding the Merger and the Company and its Subsidiaries to lenders, potential lenders and their advisors and the Company consents to the inclusion of confidential information about the Company and its Subsidiaries in an information memorandum prepared in conjunction with the syndication of the bank facilities Parent and Merger Sub may enter into to finance the Merger and the transactions contemplated hereby and the delivery of such memoranda to potential investors in such facilities on a confidential basis.

8.8. Third Party Beneficiaries. Except as provided in Section 5.9 (Indemnification; Directors’ and Officers’ Insurance), this Agreement is not intended to, and does not, confer upon any Person other than the parties hereto any rights or remedies hereunder; provided, however, that the stockholders of the Company shall be deemed third party beneficiaries solely with respect to the right to receive the Merger Consideration pursuant to Article 2 hereof.

8.9. Obligations of Parent and of the Company. Whenever this Agreement requires a Subsidiary of Parent to take any action, such requirement shall be deemed to include an undertaking on the part of Parent to cause such Subsidiary to take such action. Whenever this Agreement requires a Subsidiary of the Company to take any action, such requirement shall be deemed to include an undertaking on the part of the Company to cause such Subsidiary to take such action and, after the Effective Time, on the part of the Surviving Corporation to cause such Subsidiary to take such action.

8.10. Specific Performance. Each of the parties acknowledges and agrees that the other parties would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached. Accordingly, each of the parties agrees that the other parties shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof in any action instituted in any court of the United States or any state thereof having jurisdiction over the parties and the matter, in addition to any other remedy to which they may be entitled, at law or in equity.

8.11. Definitions. Each of the terms set forth in Annex A is defined on the page of this Agreement set forth opposite such term.

- 54 -

8.12. Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application thereof to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction.

8.13. Interpretation; Construction.

(a) The table of contents and headings herein are for convenience of reference only, do not constitute part of this Agreement and shall not be deemed to limit or otherwise affect any of the provisions hereof. Where a reference in this Agreement is made to a Section, Exhibit or Annex, such reference shall be to a Section of or Exhibit or Annex to this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.”

(b) The parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

(c) Each of the Company and Parent has or may have set forth information in its respective disclosure letter in a Section thereof that corresponds to the Section of this Agreement to which it relates. A matter set forth in one Section of a disclosure letter need not be set forth in any other Section of the disclosure letter so long as its relevance to the latter Section of the disclosure letter or Section of the Agreement is readily apparent on the face of the information disclosed in the disclosure letter to the Person to which such disclosure is being made. The fact that any item of information is disclosed in a disclosure letter to this Agreement shall not be construed to mean that such information is required to be disclosed by this Agreement. Such information and the dollar thresholds set forth herein, taken alone, shall not be determinative in interpreting the terms “material,” “Company Material Adverse Effect,” “Parent Material Adverse Effect” or other similar terms in this Agreement.

8.14. Assignment. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and permitted assigns. Subject to Section 5.9(d), no party may assign this Agreement or assign or delegate any of its rights, interests or obligations hereunder without the prior written approval of the other parties; provided, however, that Parent may assign and delegate any of its rights, interests and obligations hereunder to an Affiliate of Parent, provided that such Affiliate agrees in writing to be bound by all of the applicable provisions hereof governing such rights, interests and obligations to the same extent as Parent is bound and provided further that Parent shall continue to be bound by all of the obligations hereunder as if such assignment had not occurred and to perform such obligations to the extent

- 55 -

such Affiliate fails to do so, and that the Company promptly receive written notice of any such assignment and delegation. Any purported assignment in violation of this Agreement will be void ab initio.

8.15. No Liability. Notwithstanding anything to the contrary herein, no officer, director or stockholder of the Company shall have any liability in such capacity to Parent or Merger Sub as such with respect to this Agreement.

This Voting Agreement (this “Agreement”) is made and entered into as of November 6, 2007, by and among The Nasdaq Stock Market, Inc., a Delaware corporation (“Parent”), and [NAME OF STOCKHOLDER] (the “Stockholder”).

WHEREAS, concurrently with the execution of this Agreement, Parent, Philadelphia Stock Exchange, Inc., a Delaware corporation (the “Company”), and Pinnacle Merger Corporation, a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), have entered into an Agreement and Plan of Merger (the “Merger Agreement”) that provides for the merger (the “Merger”) of Merger Sub with and into the Company pursuant to the terms thereof;

WHEREAS, as an essential condition and inducement to Parent to enter into the Merger Agreement and in consideration therefor, the Stockholder and Parent have agreed to enter into this Agreement;

WHEREAS, as of the date hereof, the Stockholder is the record holder and beneficial owner of [ ] shares of Class B common stock, par value $0.01 per share, of the Company (the “Stockholder’s Shares”);

WHEREAS, the Stockholder and Parent have agreed that this Agreement shall only relate to [ ]¹ of the Stockholder’s Shares (such portion of the Stockholder’s Shares, together with any shares of the Company for which such portion of the Stockholder’s Shares may be exchanged or converted, the “Subject Shares”) and desires to enter into this Agreement solely with respect to such Subject Shares (for purposes of this Agreement, “beneficial ownership” shall have the meaning given to such term in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”));

WHEREAS, the Stockholder and Parent agree that this Agreement is not applicable to, and the Stockholder is not making any representations, warranties or covenants with respect to, any of the Stockholder’s Shares other than the Subject Shares; and

WHEREAS, Parent desires the Stockholder to agree, and the Stockholder is willing to agree, (i) not to transfer or otherwise dispose of any of the Subject Shares prior to the Expiration Date (as defined in Section 1.1 below) and (ii) to vote the Subject Shares so as to facilitate consummation of the Merger.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein and in the Merger Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

¹	Share number to be net of number of shares to be transferred pursuant to the ▇▇▇▇▇▇▇▇ settlement.

Agreement to Retain and Vote Shares.

1.1 Transfer and Encumbrance. The Stockholder agrees not to transfer (except as may be specifically required by court order or to any affiliate of the Stockholder or any affiliate of a parent company of the Stockholder), sell, exchange, pledge or otherwise dispose of or encumber any of the Subject Shares or to make any offer or agreement relating thereto other than in accordance with the Merger, at any time prior to the Expiration Date. As used herein, the term “Expiration Date” shall mean the earliest to occur of: (a) such date and time as the Merger shall become effective in accordance with the terms and provisions of the Merger Agreement, (b) such date as the Merger Agreement is terminated pursuant to the terms and provisions thereof, (c) July 31, 2008, and (d) any amendment of the Merger Agreement that reduces the Merger Consideration (as defined in the Merger Agreement) payable to the Stockholder or changes in a manner adverse to the Stockholder the time and manner of payment of the Merger Consideration; provided that no amendment made to the Merger Agreement in response to an Acquisition Proposal (as defined in the Merger Agreement) that the Board of Governors of the Company has determined to be a Superior Proposal (as defined in the Merger Agreement) pursuant to Section 5.2 of the Merger Agreement shall be deemed to be covered by this clause (d).

1.2 Agreement to Vote Shares. From the date hereof until the Expiration Date, at every meeting of the stockholders of the Company, and at every adjournment or postponement thereof, and, in the case of the following clause (ii) on every action or approval by written consent of the stockholders of the Company, the Stockholder irrevocably and unconditionally agrees and covenants that the Stockholder shall, including by prompt written consent if requested by Parent, vote (or cause to be voted) the Subject Shares (i) in favor of adoption of the Merger Agreement (as the same may be amended from time to time) (provided that with respect to the Written Consent on but not before 5:00 p.m. on the 20^th calendar day following the date on which Parent files a Current Report on Form 8-K as referenced in, and meeting the requirements of, the penultimate sentence of this Section 1.2) (ii) against any amendment of the Company’s certificate of incorporation or bylaws or other proposal, transaction, agreement or Acquisition Proposal involving the Company or any of its subsidiaries which amendment or other proposal or transaction could be reasonably expected to materially impede, frustrate, prevent, interfere with, postpone, delay, discourage, adversely effect or nullify, or result in a material breach of any covenant, representation or warranty or any other obligation or agreement of the Company under or with respect to, the Merger, the Merger Agreement or any of the other transactions contemplated by the Merger Agreement and (iii) in favor of any amendment or modification to the proposed certificate of incorporation and bylaws attached as exhibits to the Merger Agreement that may reasonably be requested or suggested by the Securities and Exchange Commission or its staff (it being understood that the Stockholder shall not be obligated to vote for any such amendment or modification that would adversely affect the Merger Consideration payable to the Stockholder). In the event that a meeting of the stockholders of the Company is held, the Stockholder shall appear at such meeting or otherwise cause the Subject Shares owned by the Stockholder to be counted as present for purposes of establishing a quorum. On, but no earlier than 5:00 p.m. on, the 20^th calendar day following the date on which Parent first files a Current Report on Form 8-K with the Securities and Exchange Commission regarding the Merger, which Current Report on Form 8-K shall contain as an exhibit thereto a true, complete and correct copy of the executed Merger Agreement, the Stockholder shall irrevocably execute and deliver with respect to the Subject Shares to the Company its respective counterpart of the form of Written

-2-

Consent of the stockholders of the Company attached hereto as Exhibit A (the “Written Consent”). Notwithstanding anything contained in this Agreement, the Stockholder shall not be required to vote, consent or grant any proxy in favor of any action or proposal that, if approved by the stockholders of the Company, would extend the Termination Date (as defined in the Merger Agreement).

1.3 Irrevocable Proxy. By entering into this Agreement, effective immediately following the execution and delivery of the Merger Agreement and the expiration of the 20-day period described above, the Stockholder hereby grants a proxy appointing Parent, with full power of substitution, as such Stockholder’s attorney-in-fact and proxy, for and in such Stockholder’s name, to be counted as present, to vote or to otherwise act on behalf of the Stockholder at any meeting of stockholders of the Company (including any adjournments and postponements thereof), in each case solely with respect to the Subject Shares, and to act for the Stockholder (solely with respect to the Subject Shares) on every action or approval by written consent of the stockholders of the Company and to deliver such documents and consents as may be required by the Stockholder (including, without limitation, the Written Consent) with respect to its Subject Shares, in each case solely in the manner contemplated by Section 1.2 (including in favor of adoption of the Merger Agreement) and to execute and deliver any written consents to fulfill the Stockholder’s obligations under this Agreement; provided that in no event shall the power of attorney and proxy granted hereby be exercised to take or approve of any action that would extend the Termination Date. The proxy granted by the Stockholder pursuant to this Section 1.3 is irrevocable and is granted in order to secure the Stockholder’s performance under this Agreement and is also in consideration of the entry of Parent and Merger Sub into this Agreement and the Merger Agreement. If the Stockholder fails for any reason to be counted as present or to vote or to execute and deliver written consents with respect to the Subject Shares in accordance with the requirements of Section 1.2 above, then Parent shall have the right, pursuant to this Section 1.3, to cause to be present or vote or to execute and deliver written consents with respect to the Subject Shares in accordance with the provisions of Section 1.2. The proxy granted by the Stockholder pursuant to this Section 1.3 shall terminate automatically upon the earlier of termination of the Merger Agreement prior to the Effective Time and the Termination Date (as defined in the Merger Agreement). This proxy is, and the Stockholder agrees and acknowledges that this proxy is, coupled with an interest and is irrevocable until the Expiration Date.

1.4 Revocation of Previous Proxies. The Stockholder hereby revokes any and all proxies granted with respect to the Subject Shares, prior to the proxy set forth in Section 1.3.

1.5 Intentionally Omitted.

1.6 Representations, Warranties and Covenants of the Stockholder. Subject to the Stipulation of Settlement, dated as of September 4, 2007, in connection with the action titled ▇▇▇▇▇▇▇▇ v. Philadelphia Stock Exchange, Inc., et al. (C.A. No. 2202-CC), the Stockholder hereby represents, warrants and covenants to Parent as follows:

(a) Ownership of the Subject Shares; Authority.

-3-

(b) No Conflicts or Consents. The execution and delivery of this Agreement by the Stockholder does not, and the performance by the Stockholder of the Stockholder’s obligations under this Agreement will not to the knowledge of the Stockholder: (i) conflict with or violate any law, rule, regulation, order, decree or judgment applicable to the Stockholder or by which its properties are bound or affected; (ii) result in a violation of, or a default under, or loss of any rights with respect to the Subject Shares under, or conflict with, any contract, trust, commitment, agreement, understanding, arrangement or restriction of any kind to which the Stockholder is a party or by which the Stockholder may be bound or to which the Subject Shares are subject which would materially impair the ability of the Stockholder to perform hereunder, including, without limitation, the Charter (as defined in the Merger Agreement); or (iii) result in or constitute a breach or default under, or give any person or entity rights of termination, amendment or acceleration in, any Lien (as defined in the Merger Agreement) applicable to any of the Subject Shares.

(c) Transfer of Voting Rights.

(e) Stockholder Capacity. No person executing this Agreement (or an affiliate thereof) who is or becomes prior to the Expiration Date a governor of the Company makes any agreement or understanding herein in his or her capacity as such governor or in any other capacity other than as a stockholder of the Company. The Stockholder signs solely in his, her or its capacity as the record and beneficial owner of the Subject Shares and notwithstanding anything to the contrary herein this agreement is not intended to apply to any activity that the Stockholder may otherwise conduct in the course of its business operations unrelated to its status as a stockholder of the Company.

(f) Additional Covenants and Documents. The Stockholder hereby covenants and agrees not to take any action prohibited by Section 5.2 of the Merger Agreement.

-4-

1.7 Consent and Waiver.

Miscellaneous.

2.1 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, then the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated.

2.2 Binding Effect and Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, but, except as otherwise specifically provided herein, neither this Agreement nor any of the rights, interests or obligations of the Stockholder may be assigned by the Stockholder (other than to any affiliate of the Stockholder or any affiliate of a parent company of the Stockholder, provided that such affiliate specifically agrees in writing to be bound by the terms of this Agreement) without prior written consent of Parent.

2.3 Expenses. All costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such cost or expense.

2.4 Specific Performance; Injunctive Relief.

To the fullest extent permitted by applicable law, the Stockholder agrees not to seek, and agree to waive any requirement for, the securing or posting of a bond in connection with Parent seeking or obtaining such equitable relief.
