(iii) all Liabilities for Taxes imposed with respect to, arising out of or relating to the Acquired Assets, the Assumed Liabilities or the Business other than Excluded Taxes;

(iv) all Liabilities for Transfer Taxes assumed by Purchaser pursuant to Section 8.5; and

(v) all Accrued Expenses and Deferred Revenue.

(b) Excluded Liabilities. The Assumed Liabilities shall not include any Liabilities other than those set forth in clauses (i) through (v) of Section 2.2(a), and the Parties acknowledge and agree that Purchaser and its Affiliates will not assume or be liable for any of the following Liabilities, and Sellers and their Affiliates, as applicable, shall retain all such Liabilities (collectively, the “Excluded Liabilities”):

(i) any Indebtedness of Sellers or their Affiliates;

(ii) all Liabilities for which any Seller or any of its Affiliates expressly has responsibility pursuant to the terms of this Agreement or the Related Agreements;

(iii) all Liabilities of Sellers or their Affiliates to the extent related to the Excluded Assets;

(iv) all Excluded Taxes; and

(v) Liabilities of Sellers and their Affiliates under, relating to or resulting from Parent Benefit Plans (other than Assumed Employment Agreements and the Assumed Consulting Agreement) and Liabilities relating to Business Employees or Business Consultants, except to the extent set forth in Section 2.2(a)(ii).

Section 2.3 Purchase and Sale of the Acquired Subsidiary Equity. The Parties acknowledge that, in order to facilitate the proper transfer of the Acquired Assets to Purchaser, Sellers and their Affiliates may, after consulting with Purchaser in good faith and reasonably considering Purchaser’s views, transfer some or all of the Acquired Assets and Assumed Liabilities to one or more of the Acquired Subsidiaries. In such case, each Acquired Asset or Assumed Liability so transferred to an Acquired Subsidiary shall not be transferred to Purchaser pursuant to Section 2.1(a) or Section 2.2(a), respectively, but instead shall be transferred to Purchaser by virtue of the transfer of the Acquired Subsidiary Equity. In such circumstances, upon the terms and subject to the provisions and conditions of this Agreement, at the Closing, the applicable Seller shall sell, assign, transfer and convey to Purchaser, and Purchaser shall purchase, acquire and accept from the applicable Seller, all of the Acquired Subsidiary Equity, free and clear of all Liens (other than restrictions on transfers of securities imposed by applicable federal or state securities Laws), which Acquired Subsidiary Equity shall constitute, and will constitute as of the Closing, all of the equity interests of each of the Acquired Subsidiaries.

Section 2.4 Allocation of Purchase Price. Within sixty (60) days following the Closing, Purchaser shall prepare a draft allocation of the consideration, as determined for U.S. federal income Tax purposes, among the Acquired Assets in accordance with Section 1060 of the Code and the Treasury Regulations (the “Initial Allocation”). If Parent does not object to the Initial Allocation within thirty (30) days of receipt, the Initial Allocation shall be deemed to have been accepted and agreed upon. If Parent objects to the Initial Allocation, it shall notify Purchaser of such disputed item (or items) and the basis for its objection, and Purchaser and Parent shall endeavor to resolve any such dispute. If Parent and Purchaser are unable to resolve such dispute, the disputed item(s) shall be submitted to the Accountant for resolution in a manner in accordance with Section 3.7(b). The Initial Allocation, as may be adjusted pursuant to this Section 2.4, shall be the “Final Allocation.” Each of Parent and Purchaser and their respective Affiliates shall report and file Tax Returns and shall act, in all respects and for all Tax purposes in a manner consistent with the Final Allocation, and neither Parent nor Purchaser shall take any position (whether in audits, Tax Returns, or otherwise) which is inconsistent with the Final Allocation, except as required by a “determination” within the meaning of Section 1313(a) of the Code (or any analogous provision of state, local or foreign Law).

Section 3.6 Proceedings at Closing. All proceedings to be taken and all documents to be executed and delivered by the Parties at the Closing shall be deemed to have been taken and executed and delivered simultaneously, and, except as permitted hereunder, no proceedings shall be deemed taken nor any documents executed or delivered until all have been taken, executed and delivered.

Section 3.7 Post-Closing Adjustment.

(a) Not later than ninety (90) days after the Closing Date or such other time as is mutually agreed by the Parties, Purchaser shall prepare or cause to be prepared, and deliver to Parent a revised Closing Date Statement and a revised statement of the Adjustment Amount as of the Closing Date (the “Revised Adjustment Amount”), together with such reasonably detailed data appropriate to support such revised Closing Date Statement and Revised Adjustment Amount. The Revised Adjustment Amount shall be prepared in accordance with GAAP,

consistent with the Accounting Principles. In connection with the preparation of such revised Closing Date Statement and the calculation of the Revised Adjustment Amount, Sellers shall: (A) provide Purchaser and its Affiliates (including the Acquired Subsidiaries) and their authorized representatives with reasonable access, during normal business hours, upon reasonable notice and without unreasonably interfering with Sellers’ operations of their businesses, to the relevant books, records and facilities of the Business and the relevant employees, consultants and representatives of Parent or its Affiliates who were involved in the preparation of the Closing Date Statement and Revised Adjustment Amount; and (B) cooperate in good faith with Purchaser and its Affiliates (including the Acquired Subsidiaries) and their authorized representatives, in each case, as reasonably requested by Sellers to evaluate, assess and prepare the Closing Date Statement and Revised Adjustment Amount.

(b) For thirty (30) days following the delivery of the Revised Adjustment Amount, Purchaser shall provide Sellers and their Affiliates and their authorized representatives with reasonable access to the relevant books, records, facilities, employees and representatives of Purchaser reasonably requested by Sellers to evaluate and assess the preparation of the revised Closing Date Statement and the calculation of the Revised Adjustment Amount.

(c) Within thirty (30) days following receipt of the Revised Adjustment Amount, Parent shall deliver to Purchaser in writing either its (i) agreement as to the calculation of the Revised Adjustment Amount or (ii) dispute thereof, specifying in reasonable detail the nature of its dispute. To be effective, any such notice of dispute shall include a copy of the Revised Adjustment Amount, marked to indicate those specific line items that are in dispute (the “Disputed Line Items”) and shall be accompanied by Parent’s calculation of the Revised Adjustment Amount. In the event that Parent does not provide a notice of dispute within such thirty (30) day period, Parent, on behalf of Sellers, shall be deemed to have accepted in full the Revised Adjustment Amount as prepared by Purchaser, which shall be final and binding for the purposes hereunder. During the thirty (30) days after the delivery of such dispute notice to Purchaser, Purchaser and Parent shall attempt in good faith to resolve any such dispute and finally determine the final Adjustment Amount. If, at the end of such thirty (30)-day period, Purchaser and Parent have failed to reach agreement with respect to the final Adjustment Amount, the matter shall be submitted to KPMG LLP, which shall act as arbitrator. If KPMG LLP is unable to serve, Purchaser and Parent shall jointly select another nationally recognized accounting firm that is not the independent auditor for either Parent or Purchaser and is otherwise neutral and impartial; provided, however, that if Parent and Purchaser are unable to select such other accounting firm within thirty (30) days after delivery of written notice of a disagreement, each of Purchaser and Parent shall cause its respective selected nationally recognized accounting firm to select another firm meeting the requirements set forth above or a neutral and impartial certified public accountant with significant relevant experience. The accounting firm or accountant so selected shall be referred to herein as the “Accountant.” The Accountant shall determine the final Adjustment Amount in accordance with the terms and conditions of this Agreement. In making such determination, the Accountant may only consider Disputed Line Items and must resolve the matter in accordance with the terms and provisions of this Agreement; provided that the determination of the Accountant will neither be more favorable to Purchaser than reflected in the Closing Date Statement or the Revised Adjustment Amount nor more favorable to Parent than reflected in Parent’s dispute notice. The Accountant shall deliver to Parent and Purchaser, as promptly as practicable and in any event within thirty

(30) days after its appointment, a written report setting forth the resolution of the final Adjustment Amount. Such report shall be final and binding upon the Parties to the fullest extent permitted by applicable Law and may be enforced in any court having jurisdiction. Each of Purchaser and Parent shall bear all the fees and costs incurred by it in connection with this arbitration, except that all fees and expenses relating to the foregoing work by the Accountant shall be borne by Purchaser, on the one hand, and Parent, on the other hand, in inverse proportion as they may prevail on the matters resolved by the Accountant, which proportionate allocation will also be determined by the Accountant and be included in the Accountant’s written report.

(d) On the second (2nd) Business Day after Purchaser and Parent agree to the final Adjustment Amount (or after Purchaser and Parent receive notice of any final determination of the final Adjustment Amount pursuant to the procedures set forth in Section 3.7(c)), then (i) if the final Adjustment Amount shall exceed the Estimated Adjustment Amount, then Purchaser shall pay to Sellers an amount of cash equal to such excess and (ii) if the Estimated Adjustment Amount shall exceed the final Adjustment Amount, then Sellers shall pay to Purchaser an amount of cash equal to such excess, in each of cases (i) and (ii), plus interest on such amount from the Closing Date up to but excluding the date on which such payment is made at a rate per annum equal to the Federal Funds Rate as of the Closing Date, calculated on the basis of a year of three hundred sixty (360) days and the actual number of days elapsed. Any such payment shall be made by federal funds wire transfer of immediately available funds to the account(s) of the Party entitled to receive such payment, which account(s) shall be identified by Purchaser to Parent or by Parent, on behalf of Sellers, to Purchaser, as the case may be, not less than two (2) Business Days prior to the date such payment would be due.

Section 3.8 Earn-Out.

(a) Earn-Out. As additional consideration for the Acquired Assets, following the Closing, in accordance with Section 3.8(b) and subject to Sections 3.8(c) and 3.8(d), Purchaser shall issue to BGC US a number of Purchaser Shares equal to the Earn-Out Number (each, an “Earn-Out Issuance”) for each Measurement Period in which an Earn-Out Date occurs. Each Earn-Out Issuance shall consist of Purchaser Shares that have been duly authorized, validly issued, fully paid and non-assessable, and shall be free and clear of all Liens (other than those Liens imposed by applicable federal or state securities Laws, those set forth in Purchaser’s Restated Certificate of Incorporation, in effect as of the date hereof, and those pursuant to Section 3.8(g) of this Agreement).

(b) Earn-Out Statements.

(i) With respect to each Measurement Period in which an Earn-Out Date occurs, Purchaser shall make an Earn-Out Issuance within five (5) days of the earlier of (A) the date on which Purchaser shall be required to file, and (B) the date on which Purchaser shall have filed, its Form 10-Q quarterly report or Form 10-K annual report, as applicable, in respect of the fiscal quarter in which the Earn-Out Date occurred. With respect to each Measurement Period, in the event that Purchaser determines that no Earn-Out Date occurred, within five (5) days of the earlier of (A) the date on which Purchaser shall be required to file, and (B) the date on which Purchaser shall have filed,

its Form 10-Q quarterly report or Form 10-K annual report, as applicable, in respect of the fiscal quarter corresponding to such Measurement Period, Purchaser shall deliver to Parent a statement that sets forth in reasonable detail its calculation of the Business Revenue for such Measurement Period (such statement, the “Earn-Out Statement”); it being understood and agreed that Purchaser shall have no obligation to deliver any Earn-Out Statement for any fiscal quarter in a Measurement Period in which an Earn-Out Issuance has been made. With respect to each Measurement Period, if Purchaser fails to deliver the Earn-Out Statement on the date on which it is due pursuant to the prior sentence (the “Earn-Out Statement Deadline”), then an Earn-Out Date shall be deemed to have occurred with respect to such Measurement Period, and Purchaser shall make an Earn-Out Issuance with respect to such Measurement Period within five (5) days following the Earn-Out Statement Deadline. Each Earn-Out Statement shall provide all reasonable backup calculations necessary to arrive at Purchaser’s calculation of the Business Revenue set forth on such Earn-Out Statement for such Measurement Period and such backup calculations shall be certified by the corporate controller of Purchaser as having been calculated in accordance with the terms of this Agreement.

(ii) With respect to any Measurement Period in which the Purchaser determines that no Earn-Out Date occurred, Purchaser shall, and shall cause its Affiliates to, keep complete and accurate records in reasonably sufficient detail to enable Purchaser, Parent and Sellers to calculate the Business Revenue for such Measurement Period. With respect to each Measurement Period in which the Purchaser determines that no Earn-Out Date occurred, Purchaser shall provide Parent, Sellers and their respective Affiliates and their authorized representatives with access, during normal business hours, upon reasonable notice and without unreasonably interfering with Purchaser’s operation of its businesses (including the Business), to all books, records, facilities, employees and representatives of Purchaser reasonably requested by Parent, Sellers and their respective Affiliates to evaluate and assess the calculation of Business Revenue, including using commercially reasonable efforts to cause Purchaser’s accountants to cooperate and assist Parent, Sellers and their respective Affiliates and their respective representatives in evaluating the calculation of Business Revenue.

(iii) Within thirty (30) days of the receipt of the Earn-Out Statement for the applicable Measurement Period, Parent may deliver to Purchaser in writing its dispute of such Earn-Out Statement, specifying in reasonable detail the nature of its dispute. During the thirty (30) days after the delivery of such dispute notice to Purchaser, Purchaser and Parent shall attempt in good faith to resolve any such dispute and finally determine the Business Revenue for such Measurement Period. If, at the end of such thirty (30) day period, Purchaser and Parent have failed to reach agreement with respect to the Business Revenue for such Measurement Period, then the matter shall be submitted to the Accountant, which shall act as arbitrator. The Accountant shall determine the Business Revenue for such Measurement Period in accordance with the terms and conditions of this Agreement. The Accountant shall deliver to Parent and Purchaser, as promptly as practicable and in any event within thirty (30) days after its appointment, a written report setting forth the resolution of the Business Revenue for such Measurement Period. Such report shall be final and binding upon the Parties to the fullest extent permitted by applicable Law and may be enforced in any court having jurisdiction. Each

of Purchaser and Parent shall bear all the fees and costs incurred by it in connection with this arbitration, except that all fees and expenses relating to the foregoing work by the Accountant shall be borne by the Party that does not prevail on the matters resolved by the Accountant.

(iv) On the second (2^nd) Business Day after Purchaser and Parent agree on the Business Revenue for any Measurement Period (or after Purchaser and Parent receive notice of any final determination of the Business Revenue for such Measurement Period pursuant to the procedures set forth in Section 3.8(b)(iii)), then if the Business Revenue for such Measurement Period equals or exceeds the Target Revenue, then Purchaser shall make the Earn-Out Issuance to BGC US for such Measurement Period.

(c) Acceleration Events. If any Acceleration Event has occurred, Purchaser shall issue to BGC US, no later than the date on which such Acceleration Event has occurred, a number of Purchaser Shares equal to the Acceleration Issuance Number (an “Acceleration Issuance”). An Acceleration Issuance shall consist of Purchaser Shares that have been duly authorized, validly issued, fully paid and non-assessable, and shall be free and clear of all Liens (other than those Liens imposed by applicable federal or state securities Laws, those set forth in Purchaser’s Restated Certificate of Incorporation and those pursuant to Section 3.8(g) of this Agreement). If an Acceleration Issuance shall have occurred, then Purchaser shall have no further obligations pursuant to Section 3.8(a) and (b), other than any obligation of Purchaser to make an Earn-Out Issuance for a Measurement Period that has occurred prior to the date of the Acceleration Event.

(d) Adjustment of Earn-Out Number for Anti-Dilution.

(i) Earn-Out Number. The “Earn-Out Number” shall mean the Initial Earn-Out Number, as it may be adjusted (if at all) pursuant to the remaining provisions of this Section 3.8(d); provided that, if more than one subsection of this Section 3.8(d) is applicable to a single event, the subsection shall be applied that produces the largest adjustment and no single event shall cause an adjustment under more than one subsection of this Section 3.8(d) so as to result in duplication. Any adjustments pursuant to this Section 3.8(d) shall be made successively whenever an event referred to herein shall occur.

(ii) Adjustments for Stock Dividends and Distributions. If Purchaser pays dividends or makes other distributions on Purchaser Shares in the form of Purchaser Shares, then the Earn-Out Number in effect immediately prior to the Ex-Date for such dividend or distribution will be multiplied by the following fraction:

OS₁/OS₀, where

OS₀ = the number of Purchaser Shares outstanding immediately prior to Ex-Date for such dividend or distribution.

OS₁ = the sum of the number of Purchaser Shares outstanding immediately prior to the Ex-Date for such dividend or distribution

plus the total number of Purchaser Shares constituting such dividend or distribution.

If any dividend or distribution of the type described in this Section 3.8(d)(ii) is declared but not so paid or made, the Earn-Out Number shall be immediately readjusted, effective as of the date the Board of Directors of Purchaser determines not to pay such dividend or distribution, to the Earn-Out Number that would then be calculated if such dividend or distribution had not been declared.

(iii) Subdivisions, Splits and Combinations of the Purchaser Shares. If Purchaser subdivides, splits or combines the Purchaser Shares, then the Earn-Out Number in effect immediately prior to the effective date of such share subdivision, split or combination will be multiplied by the following fraction:

OS₁/OS₀, where

OS₀ = the number of Purchaser Shares outstanding immediately prior to the effective date of such share subdivision, split or combination.

OS₁ = the number of Purchaser Shares outstanding immediately after the opening of business on the effective date of such share subdivision, split or combination.

(iv) Issuance of Stock Purchase Rights. If Purchaser issues to all or substantially all holders of the Purchaser Shares rights or warrants (other than rights or warrants issued pursuant to a dividend reinvestment plan or share purchase plan or other similar plans) entitling them to subscribe for or purchase the Purchaser Shares at less than the Current Market Price on the date fixed for the determination of stockholders entitled to receive such rights or warrants, then the Earn-Out Number in effect immediately prior to the Ex-Date for such distribution will be multiplied by the following fraction:

(OS₀ + X) / (OS₀ + Y), where

OS₀ = the number of Purchaser Shares outstanding immediately prior to the Ex-Date for such distribution.

X = the total number of Purchaser Shares issuable pursuant to such rights or warrants.

Y = the number of Purchaser Shares equal to the aggregate price payable to exercise such rights or warrants divided by the Current Market Price.

In determining the aggregate offering price payable to exercise such rights or warrants for such Purchaser Shares, there shall be taken into account any consideration received for such rights or warrants and the value of such consideration (if other than cash, to be determined in good faith

by the Purchaser board of directors or committee thereof). If an adjustment to the Earn-Out Number is required under this clause (iv), delivery of any additional Purchaser Shares that may be deliverable upon conversion as a result of an adjustment required under this clause (iv) shall be delayed to the extent necessary in order to complete the calculations provided in this clause (iv). To the extent that Purchaser Shares are not delivered after the expiration of such rights or warrants, the Earn-Out Number shall be readjusted to the Earn-Out Number that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of Purchaser Shares actually delivered. If such rights or warrants are not so issued, the Earn-Out Number shall again be adjusted to be the Earn-Out Number that would then be in effect if such Ex-Date for such distribution had not been fixed.

(v) Dilutive Issuance. If Purchaser issues Purchaser Shares in a Dilutive Issuance, then the Earn-Out Number in effect immediately prior to the Ex-Date for such issuance will be multiplied by the following fraction:

(OS₀ + X) / (OS₀ + Y), where

OS₀ = the number of Purchaser Shares outstanding immediately prior to the Ex-Date for such Dilutive Issuance.

X = the total number of Purchaser Shares issued in the Dilutive Issuance.

Y = the number of Purchaser Shares equal to the aggregate price payable for the Purchaser Shares issued divided by the Current Market Price.

In determining the aggregate offering price payable for such Purchaser Shares, there shall be taken into account any consideration received by Purchaser for such Purchaser Shares and the value of such consideration (if other than cash, to be determined in good faith by the Purchaser board of directors). If an adjustment to the Earn-Out Number is required under this clause (v), delivery of any additional Purchaser Shares that may be deliverable upon conversion as a result of an adjustment required under this clause (v) shall be delayed to the extent necessary in order to complete the calculations provided in this clause (v).

(vi) Distributions. If Purchaser distributes to all or substantially all holders of Purchaser Shares evidences of indebtedness, shares of capital stock, securities, cash or other assets (excluding any dividend or distribution referred to in clause (ii) of this Section 3.8(d), any rights or warrants referred to in clause (iv) of this Section 3.8(d), and any Non-Dilutive Cash Distribution), then the Earn-Out Number in effect on the first Business Day of the immediately succeeding fiscal quarter will be multiplied by the following fraction:

SP₀ / (SP₀ – FMV), where

SP₀ = the Current Market Price per Purchaser Share on the Ex-Date for such distribution.

FMV = the fair market value of the portion of the distribution applicable to one Purchaser Share on such date, with such fair market value equal to (A) in the case of any cash, the amount of such cash, (B) in the case of any securities that trade on a securities exchange, the opening price of such security on such securities exchange immediately after the distribution and (C) in the case of any other asset, as reasonably determined by the Purchaser board of directors (or committee thereof).

With respect to making an adjustment to the Earn-Out Number with respect to a cash distribution, Purchaser may at its election (in lieu of making any adjustments pursuant to this clause (vi) for such cash distribution) deliver to BGC US an amount in cash payable on all Purchaser Shares that may be issuable in all Earn-Out Issuances subsequent to the record date of such cash distribution as if BGC US was the holder of such Purchaser Shares as of such record date.

(vii) Self-Tender Offers. If Purchaser or any of its Subsidiaries completes a tender offer, made to all or substantially all holders of Purchaser Shares, for the Purchaser Shares where the cash and the value of any other consideration included in the payment per share of the Purchaser Shares exceeds the arithmetic average of (x) the closing price per Purchaser Share on the trading day immediately prior to the announcement of the price of the tender offer and (y) the closing price per Purchaser Share on the closing date of the tender offer, then the Earn-Out Number in effect at the open of business on the day following the expiration of the tender offer will be multiplied by the following fraction:

(AC + (SP₀ x OS₁)) / (OS₀ x SP₀), where

SP₀ = the arithmetic average of (x) the closing price per Purchaser Share on the trading day immediately prior to the announcement of the price of the tender offer and (y) the closing price per Purchaser Share on the closing date of the tender offer.

OS₀ = the number of Purchaser Shares outstanding immediately prior to the expiration of the tender offer, including any shares validly tendered and not withdrawn.

OS₁ = the number of Purchaser Shares outstanding immediately after the expiration of the tender offer, excluding any shares validly tendered and not withdrawn.

AC = the aggregate cash and fair market value of the other consideration payable in the tender or exchange offer, with such fair market value equal to (A) in the case of any securities that trade on a securities exchange, the opening price of such security on such securities exchange immediately after the completion of

the tender offer and (B) in the case of any other asset, as reasonably determined by the Purchaser board of directors (or committee thereof).

If the application of this clause (vii) to any tender offer would result in a decrease in the Earn-Out Number, no adjustment shall be made for such tender offer or exchange offer under this clause (vii). If an adjustment to the Earn-Out Number is required under this clause (vii), delivery of any additional Purchaser Shares that may be deliverable as a result of an adjustment required under this clause (vii) shall be delayed to the extent necessary in order to complete the calculations provided for in this clause (vii).

(viii) Rounding of Calculations; Minimum Adjustments. All calculations under this Section 3.8(d) shall be made to the nearest one-hundredth (1/100th) of a share.

(ix) Proceedings Relating to any Adjustment. In connection with any action that would require an adjustment to the Earn-Out Number pursuant to this Section 3.8(d), Purchaser shall take any action that may be necessary, including obtaining regulatory, stock exchange or stockholder approvals or exemptions, in order that Purchaser may thereafter validly and legally issue as fully paid and nonassessable all shares of Purchaser Shares that Parent is entitled to receive pursuant to this Section 3.8.

(x) Consequences of Certain Transactions. In the event of any reclassification of the Purchaser Shares or a consolidation, merger, combination or binding share exchange involving Purchaser, in each case in which holders of Purchaser Shares are entitled to receive cash, securities or other property for Purchaser Shares (“Reference Property”), the right to receive Purchaser Shares shall be substituted with the right to receive an amount of Reference Property that would have been deliverable in such transaction with respect to each such Purchaser Share; provided that nothing in this clause (x) is intended to limit any such transaction from triggering an Acceleration Event.

(xi) Notice. In the event that Purchaser shall have taken any action of the type described in this Section 3.8(d), Purchaser shall give notice to Parent, in the manner set forth in Section 11.1, which notice shall specify the record date, if any, with respect to any such action and the date on which such action has taken place. Such notice shall also set forth the facts with respect thereto as shall be reasonably necessary to indicate the effect on the Earn-Out Number. Such notice shall be given no later than 10 days following the taking of such action. Failure to give such notice, or any defect therein, shall not affect the legality or validity of any such action.

(xii) Notwithstanding any of the foregoing, the Earn-Out Number will not be adjusted:

(1) upon the issuance of any Purchaser Shares pursuant to any present or future employee stock plan providing for the reinvestment of dividends or interest payable on Purchaser’s securities and the investment of additional optional amounts in Purchaser Shares under any employee stock plan;

(2) upon the issuance of any Purchaser Shares or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of, or assumed by, Purchaser or any of Purchaser’s subsidiaries; or

(3) upon the issuance of any Purchaser Shares pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (2) of this subsection and outstanding as of the date of this Agreement.

(e) Transactions in Purchaser Shares During Pricing Period. During the twenty (20) trading days immediately preceding the Closing Date, no member of the Parent Group, member of the Cantor Group or any Acquired Subsidiary shall, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any Purchaser Shares or any securities convertible into or exchangeable or exercisable for Purchaser Shares, whether now owned or hereafter acquired by Parent or with respect to which Parent has or hereafter acquires the power of disposition, or file, or cause to be filed, any registration statement under the Securities Act, with respect to any of the foregoing (collectively, the “Lock-Up Securities”) or (ii) enter into any swap, derivative or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities or the potential economic consequences of this Earn-Out provision, whether any such swap, derivative or other transaction is to be settled by delivery of Purchaser Shares or other securities, in cash or otherwise (each, a “Disposition Transaction”); provided that any member of the Parent Group or the Cantor Group or any Acquired Subsidiary may, at any time, as part of their ordinary course of business, make any Disposition Transaction (1) for the accounts of their unaffiliated customers or (2) in connection with customer trading, including as principal, in any currently existing, quoted stock index or publicly traded exchange-traded fund on a national stock exchange where the number of Purchaser Shares involved in the Disposition Transaction is consistent with the representation of Purchaser Shares in such stock index or exchange-traded fund During the twenty (20) trading days immediately preceding the Closing Date, Purchaser shall not, directly or indirectly, (i) offer, purchase, contract to purchase, sell any option or contract to sell, purchase any option or contract to purchase, acquire any option, right or warrant for the purchase of, or otherwise purchase or acquire any Purchaser Shares or any securities convertible into or exchangeable or exercisable for Purchaser Shares, whether now owned or hereafter acquired by Purchaser or with respect to which Purchaser has or hereafter acquires the power of disposition, or file, or cause to be filed, any tender offer document under the Exchange Act, with respect to any of the foregoing or (ii) enter into any swap, derivative or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of Purchaser Shares, whether any such swap, derivative or other transaction is to be settled by delivery of Purchaser Shares or other securities, in cash or otherwise (each, an “Acquisition Transaction”); provided that Purchaser may, at any time, as part of its ordinary course of business, make any (A) Acquisition Transaction for the accounts of its unaffiliated customers, (B) purchases pursuant to any employee stock purchase plans that require such purchases and (C) purchases pursuant to any share repurchase program consistent in amount and timing with past practice; provided that prior to effecting any such repurchase, Purchaser shall, through a third-party broker engaged in such

repurchase, offer BGC US to sell to Purchaser such Purchaser Shares at the price at which Purchaser intends to effect such repurchase. Each Party shall bear and be responsible for the commissions of its broker in such transaction, and no Party shall bear or be responsible for the commission of the other Party in such transaction or any other commission. To the extent that BGC US does not agree to sell such Purchaser Shares at such price, neither Purchaser nor Purchaser’s third-party broker shall offer to repurchase Purchaser Shares during the twenty (20) trading days immediately preceding the Closing Date at price that is higher than that offered to BGC US (which price may be based on volume weighted average pricing methodology). If BGC US agrees to sell such Purchaser Shares to Purchaser, then such purchase will be settled at such time that BGC US would otherwise be entitled to receive an equal or greater number of Purchaser Shares pursuant to an Earn-Out Issuance (it being agreed that, if the Closing does not occur for any reason, then all purchases of Purchaser Shares by Purchaser from BGC US pursuant to this Section 3.8(e) shall be null and void with no interest, penalty or other payment to either Party in respect of such purchase).

(f) Ownership Limitation. In the event that any member of the Parent Group or Cantor Group would be prohibited under applicable Law from being the beneficial owner (as defined in Section 13(d)-3 of the Exchange Act) of voting securities representing more than 9.9% of Purchaser’s outstanding voting securities (the “Ownership Limitation”), then Purchaser shall be entitled to defer any Earn-Out issuance (or portion thereof) otherwise required to be issued hereunder if such Earn-Out Issuance (or portion thereof) would cause the Ownership Limitation to be exceeded, until such time as such ownership of Purchaser’s outstanding voting securities in excess of the Ownership Limitation would not be prohibited by such applicable Law; provided that, until such Purchaser Shares shall have been issued, Purchaser shall make payments to BGC US equal to the dividends that would have been payable on such Purchaser Shares. The Purchaser agrees to take all reasonable actions as may be requested by any member of the Parent Group or the Cantor Group to obtain all necessary or required approvals under applicable Law so such member of the Parent Group or the Cantor Group, as applicable, may hold outstanding voting securities in excess of the Ownership Limitation. In the event that the sum of all of the Earn-Out Issuances would cause Purchaser to issue a number of Purchaser Shares in excess of 19.99% of the number of Purchaser Shares outstanding as of the date of this Agreement (the “Share Issuance Limitation”) and such issuances would not be permitted by the listing rules of NASDAQ as of the date hereof without receipt of approval of the Purchaser’s shareholders, then Purchaser shall substitute cash for Purchaser Shares in any Earn-Out Issuance solely to the extent required so that the sum of all of the Earn-Out Issuances would cause Purchaser to issue a number of Purchaser Shares equal to the Share Issuance Limitation, with such cash equal to (i) the number of Purchaser Shares that Purchaser otherwise would be obligated to issue to BGC US pursuant to such Earn-Out Issuance, multiplied by (ii) the Current Market Price as of the date on which Purchaser otherwise would be obligated to issue such Purchaser Shares to BGC US pursuant to such Earn-Out Issuance, and such substitution shall be made with respect to the earliest Earn-Out Issuances following the Closing.

(g) Disposition Limitations. No member of the Parent Group or Cantor Group shall directly or indirectly (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of Purchaser Shares or any securities convertible into or exchangeable or exercisable for Purchaser Shares, or (ii) enter into any swap

or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the such securities, whether any such swap or transaction is to be settled by delivery of Purchaser Shares or other securities, in cash or otherwise (any such transaction, “Potentially Disruptive Sale Transaction”), in an aggregate amount that, together with any other Potentially Disruptive Sale Transaction entered into in the immediately preceding four calendar weeks is an aggregate amount greater than 4.90% of the number of outstanding Purchaser Shares on such date; provided that none of the following shall, individually or in the aggregate, constitute a Potentially Disruptive Sale Transaction: (A) any transaction effected through an Underwritten Offering (as defined in the Registration Rights Agreement) pursuant to Section 2.2 of the Registration Rights Agreement, (B) any transaction involving Purchaser Shares in an amount on any date that is less than the greater of (1) the DTV for such date or (2) the immediately preceding Four Week ADTV or (C) any private sale to a purchaser of such Purchaser Shares that is purchasing for investment without an intention at such time of distributing or selling such Purchaser Shares; provided, further, that, if such purchaser acquires pursuant to such private sale a number of Purchaser Shares greater than an amount equal to (x) the Percentage Amount multiplied by (y) the number of outstanding Purchaser Shares as of the date of such transfer, then such purchaser shall agree in writing with Purchaser to be bound by disposition limitations substantially equivalent to those set forth in this Section 3.8(g). “Percentage Amount” means 4.90%, which shall be proportionately increased in the event that the percentage of the outstanding Purchaser Shares held by any member of the Parent Group or Cantor Group shall be increased as a result of an action taken by Purchaser, including a share repurchase, spin-off, split-off or other transaction.

(h) Exemptions. Purchaser shall take all necessary actions to ensure that the acquisition and ownership of the Purchaser Shares contemplated to be issued to BGC US pursuant to this Section 3.8 (or any permitted assignee pursuant to Section 11.8) shall not trigger any rights plan or other similar plan that Purchaser may adopt in the future (it being understood that such exemption shall not apply to any other Purchaser Shares that any member of the Parent Group or Cantor Group may acquire).

(a) From the date hereof until the earlier of the Closing and termination of this Agreement in accordance with its terms, subject to applicable Law, each (i) of Sellers, on the one hand, and Purchaser, on the other, will permit the other and their respective representatives to have reasonable access, during regular business hours and upon reasonable advance notice for purposes reasonably consistent with this Agreement, to their respective properties, premises, facilities, employees and representatives and books and records to the extent related to the transactions contemplated by this Agreement or by the Related Agreements, (ii) Parent or Purchaser, as applicable, shall direct its respective employees, agents and representatives and shall cause the employees, agents and representatives of its respective Affiliates, to cooperate fully with Purchaser or Sellers, as the case may be, and its respective representatives to the extent related to the transactions contemplated by this Agreement or by the Related Agreements and (iii) Sellers shall, and shall cause their Affiliates to, furnish promptly to Purchaser a copy of (x)

each regulatory report, schedule, form, registrations and other documents (and any amendment with respect thereto) filed with any Governmental Authority to the extent related to the Business, (y) the internal or external reports related to the Business and (z) all other information concerning the Business as Purchaser may reasonably request; provided, however, that nothing herein shall obligate any Seller or any Acquired Subsidiary or any of their respective Affiliates to take any actions that would (i) unreasonably interrupt or interfere with the normal course of their businesses or (ii) result in any waiver of attorney-client privilege or violate any Laws or the terms of any Contract to which Seller, any Acquired Subsidiaries or any of their Affiliates is a party or to which any of their respective assets are subject; provided, further, that prior to the expiration of any waiting period under the HSR Act and other similar Law applicable to the transactions contemplated by this Agreement, Purchaser and its representatives shall only be permitted such reasonable access which, in Seller’s discretion, after consultation with counsel, is appropriate during such review process. Purchaser shall comply, and shall cause its representatives to comply, with all safety, health and security rules applicable to the premises being visited. In each case, Purchaser and each Seller, as applicable, and its respective representatives shall comply with the confidentiality obligations contained herein.

(b) In addition to the confidentiality arrangements contained herein, all information provided or obtained in connection with the transactions contemplated by this Agreement (including pursuant to subsection (a) above) will be held by Purchaser in accordance with the Non-Disclosure Agreement, dated October 13, 2011, as amended, between Purchaser and Parent (the “Non-Disclosure Agreement”). In the event of a conflict or inconsistency between the terms of this Agreement and the Non-Disclosure Agreement, the terms of this Agreement will govern.

(c) Each party hereto shall preserve and keep all books and records and all information relating to the accounting, business and financial affairs that are retained by Parent or any of its Affiliates or obtained by Purchaser hereunder, as the case may be, which information relates to the Business, the Acquired Assets or the Acquired Subsidiaries prior to the Closing, for five (5) years after the Closing Date, or for any longer period as may be (i) required by any Governmental Authority or (ii) reasonably necessary with respect to the prosecution or defense of any legal action that is then pending or threatened or audit and with respect to which the requesting Party has notified the other Party as to the need to retain such books, records or information. Notwithstanding the foregoing provisions of this Section 6.2(c), the provisions of Article VIII shall govern the preservation, retention and sharing of Tax Returns and Tax work papers. After the Closing Date, each Party shall, and shall cause its Subsidiaries to, permit the other Party and their respective representatives to have reasonable access to, and to inspect and copy, all materials referred to in this Section 6.2(c) and to meet with officers and employees of the other Party and its Subsidiaries on a mutually convenient basis in order to obtain explanations with respect to such materials, to obtain additional information, to call such officers and employees as witnesses and for any other reasonable business purpose.

Section 6.3 Notice. Until the Closing, each of Parent and Purchaser shall use commercially reasonable efforts to promptly notify the other in writing of any fact, change, condition, circumstance or occurrence of any event of which it is aware that will or is reasonably likely to result in the conditions set forth in Section 7.2(a) or (b) becoming incapable of being satisfied. Until the Closing, Parent shall use commercially reasonable efforts to notify Purchaser

in writing promptly following any Person set forth on Section 6.3 of the Seller Disclosure Letter learning that Parent or any of its Affiliates shall have received from a Material Customer proper written notice (in accordance with the notice provisions of the applicable Contract) of termination or non-renewal of such Material Customer’s contract that constitutes an Acquired Contract.

Section 6.4 Efforts; Filings.

(a) Subject to the terms and conditions of this Agreement, each of Parent and Purchaser shall use its reasonable best efforts to take, agree to take, or cause to be taken, any and all actions and to do, or cause to be done, any and all things necessary, proper or advisable under applicable Law or otherwise, so as to, as promptly as practicable, consummate the transactions contemplated by this Agreement and the Related Agreements, and each shall, and shall cause its respective Affiliates (and in the case of Parent, the Cantor Group) to, cooperate fully to that end. Subject to Section 6.2 and the Non-Disclosure Agreement, each Party shall (i) permit the other Parties to review and discuss in advance, and consider in good faith the views of the other Parties in connection with, any proposed written (or any material proposed oral) communication with any Governmental Authority regarding the transactions contemplated by this Agreement and the Related Agreements; and (ii) promptly inform the other Parties (and if in writing, provide the other Parties or their counsel with copies of) all correspondence, filings and communications between the Party and any Governmental Authority regarding the transactions contemplated by this Agreement and the Related Agreements. The Parties may, as each deems advisable or necessary, reasonably designate any competitively sensitive material provided to the other Parties under this Section 6.4 as “outside counsel only.” Such materials and the information contained therein shall be given only to the outside legal counsel of the recipient and will not be disclosed by such outside counsel to employees, officers or directors of the recipient unless express permission is obtained in advance from the source of the materials (Purchaser or Sellers, as the case may be) or its legal counsel; provided, however, that materials provided pursuant to this Section 6.4 may be redacted (x) to remove references concerning the valuation of the Business, (y) as necessary to comply with contractual arrangements, or (z) as necessary to address reasonable legal privilege concerns.

(b) Without limiting the provisions of Section 6.4(a) and notwithstanding any other provision of this Agreement, Purchaser shall take any and all steps necessary to avoid or eliminate each and every impediment under any antitrust, competition or trade regulation law (including the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules and regulations promulgated thereunder (the “HSR Act”)) that may be asserted with respect to the transactions contemplated by this Agreement and the Related Agreements so as to enable the Closing to occur expeditiously; provided, however, that Purchaser shall not be obligated to divest: (i) the Business, or (ii) assets unrelated to a marketplace of transactions in U.S. Treasury Securities, except to the extent that such assets are immaterial or (iii) any technology that Purchaser is required pursuant to the next sentence to be willing to agree to license. In addition, if required to consummate the transactions contemplated by this Agreement and the Related Agreements, Purchaser will, with respect to any third-party competitor of the Business, both (A) license (non-exclusively with respect to Purchaser) Purchaser’s Competitive Technology for use by such competitor in operating a marketplace of transactions in U.S. Treasury Securities and (B) permit access to, and the right to modify, the source code underlying such Competitive

Technology. For purposes of the foregoing sentence, the Parties intend that such grant of a license and access shall, if required to consummate the transactions contemplated by this Agreement and the Related Agreements, be for no payment or royalty made to Purchaser or any of its Affiliates, and that such license shall, if required to consummate the transactions contemplated by this Agreement and the Related Agreements, be perpetual. “Competitive Technology” shall mean all technology of Purchaser and its Subsidiaries that is used by a third-party competitor of the Business related to a marketplace of transactions in U.S. Treasury Securities, including, if required to consummate the transactions contemplated hereby, any updates and upgrades of such technology and access to maintenance of such technology. In addition, Purchaser and Parent shall defend through litigation on the merits in a U.S. District Court (or any state trial court) any claim asserted in court by any party in order to avoid entry of, or to have vacated or terminated, any decree, order or judgment (whether temporary, preliminary or permanent) that would restrain, prevent or delay the Closing. For the avoidance of doubt, if Purchaser has complied with its obligations set forth above, and nonetheless a Governmental Authority has brought an action under any antitrust, competition or trade regulation Law that has resulted in a final, permanent Governmental Order preventing the Closing, then either Party will be entitled to terminate this Agreement pursuant to Section 9.1(b) without incurring any obligations to each other in connection with such termination. Notwithstanding anything to the contrary contained in this Agreement, Purchaser shall have the principal responsibility for devising and implementing the strategy for obtaining any necessary antitrust or competition clearances and shall take the lead in all meetings and communications with any Governmental Authority in connection with obtaining any necessary antitrust or competition clearances. No Party shall participate in any meeting with any Governmental Authority in connection with this Agreement (or make oral submissions at meetings or in telephone or other conversations) unless it consults with the other Parties in advance and, to the extent not prohibited by such Governmental Authority, gives the other Parties the opportunity to attend and participate thereat.

(c) As promptly as practicable but in no event later than thirty (30) days after the date of this Agreement, Parent and Purchaser shall prepare and file complete notifications with the Federal Trade Commission and the United States Department of Justice as are required to comply with the HSR Act. In the event that the Parties receive a formal request for additional information or documentary materials after an initial notification pursuant to the HSR Act, the Parties will use their respective reasonable best efforts to respond to such request as promptly as possible and counsel for the Parties will reasonably cooperate during the entirety of any such process.

(d) Each of Parent and Purchaser agrees to use its reasonable best efforts to prepare all documentation, to effect all filings and to obtain all permits, consents, clearances, approvals and authorizations of all Governmental Authorities and other Persons necessary to consummate the transactions contemplated by this Agreement and the Related Agreements as promptly as practicable.

(e) Purchaser and Sellers shall not, and shall not permit any of their Subsidiaries to, acquire or agree to acquire by merging or consolidating with, or by purchasing a substantial portion of the assets of or equity in, or by any other manner, any business or any corporation, partnership, association or other business organization or division thereof, or otherwise acquire or agree to acquire any assets or take any other action if the entering into of a

definitive agreement relating to or the consummation of such acquisition, merger, consolidation or other action could reasonably be expected to (i) impose any delay in the obtaining of, or significantly increase the risk of not obtaining, any authorizations, consents, orders, declarations or approvals of any Governmental Authority necessary to consummate the transactions contemplated by this Agreement or the expiration or termination of any applicable waiting period, (ii) significantly increase the risk of any Governmental Authority entering an order prohibiting the consummation of the transactions contemplated by this Agreement and the Related Agreements, (iii) significantly increase the risk of not being able to remove any such order on appeal or otherwise, or (iv) delay or prevent the consummation of the transactions contemplated by this Agreement and the Related Agreements.

Section 6.5 Non-Solicitation of Alternative Transaction. From and after the date of this Agreement until the earlier of the Closing or the termination of this Agreement in accordance with its terms, Sellers shall not, nor shall they permit any of their respective Subsidiaries to, nor authorize or permit any director, officer or employee of Sellers or any of their respective Affiliates to, and shall use reasonable best efforts to cause any investment banker, attorney, accountant or other advisor or representative of Sellers or any of their respective Affiliates not to, directly or indirectly, (a) solicit, initiate or knowingly encourage, or take any other action knowingly to facilitate, any Alternative Proposal or (b) enter into, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any person any information with respect to, or otherwise cooperate in any way with, any Alternative Proposal. The term “Alternative Proposal” means any inquiry, proposal or offer from any Person relating to any direct or indirect acquisition, in one transaction or a series of related transactions (including any merger, consolidation, exchange offer, binding share exchange, business combination, recapitalization, liquidation, dissolution, joint venture or similar transaction) of any equity or voting interests of an Acquired Subsidiary or twenty-five percent (25%) or more of the Acquired Assets; provided that an Alternative Proposal shall not include any of the transactions contemplated by this Agreement or the Related Agreements or any inquiry, offer or proposal to acquire all or a majority of the outstanding common stock or equity interest of Parent or BGC Holdings.

In addition to the foregoing, in the event that any party breaches or violates its obligations under this Section 6.6(a) prior to or after the Closing because it did not have knowledge that a Person was or was formerly an employee or consultant of the other party at the time of the solicitation, hiring or engagement, as the case may be, of such Person, then the breaching party shall not be deemed to be in breach or violation of this Section 6.6(a) so long as it shall have taken actions to cure such breach reasonably promptly following receipt of notice from the non-breaching party that such Person was or was formerly an employee or consultant of the non-breaching party

(a) Notwithstanding anything in this Agreement to the contrary, this Agreement shall not constitute an agreement to assign any Contract or Lease or any claim, right or benefit arising thereunder or resulting therefrom if an attempted assignment thereof, without the consent of a third party thereto, would constitute a breach or other contravention thereof or be ineffective with respect to any party thereto or would violate any applicable Law.

(b) With respect to any such Contract or Lease and any claim, right or benefit arising thereunder or resulting therefrom, Sellers shall, and shall cause their Affiliates to, use commercially reasonable efforts, and Purchaser shall reasonably cooperate with Sellers and their Affiliates, to obtain, or cause to be obtained, prior to Closing, any consent, substitution, approval or amendment (which requests for consents, substitution, approval or amendment shall be in form and substance reasonably satisfactory to Purchaser) required to novate or assign such Contract or Lease; provided, however, in no event shall any Seller, Purchaser or their Affiliates be obligated to pay any money (other than a de minimis amount) to any Person or to otherwise offer or grant other financial or other accommodations to any Person in connection with obtaining any such consent, substitution, approval or amendment with respect to any Contract or Lease.

(c) If any consent, substitution, approval or amendment required to novate or assign any Contract or Lease is not obtained prior to Closing, until the earlier of such time as such consent is obtained or one (1) year following the Closing Date, Sellers and Purchaser will each use reasonable best efforts to establish an agency type or other similar arrangement reasonably satisfactory to Sellers and Purchaser under which Purchaser would obtain, to the fullest extent practicable, the claims, rights and benefits and assume the corresponding liabilities and obligations thereunder from and after the Closing in accordance with this Agreement (including by means of any subcontracting, sublicensing or subleasing arrangement) and under which the applicable Seller or its Affiliates would enforce at the direction of and for the benefit of Purchaser, any and all claims, rights and benefits of such Seller or Affiliate against a third party thereto.

Except as otherwise set forth in Section 6.10(b), all Business Employees who accept such offers of employment shall become “Continuing Business Employees” as of the Closing Date. Effective as of the Closing Date (or, if later, the date such individual becomes a Business Employee pursuant to Section 6.10(b)), Sellers or their Affiliates shall cause (i) each Continuing Business Employee to be fully vested in such employee’s benefits under any Parent Benefit Plan that is a qualified or non-qualified pension or retirement plan and (ii) the employment of each of the Continuing Business Employees with Sellers or their Affiliates (other than those employed by an Acquired Subsidiary or described in Section 6.10(b)) to be terminated.

(b) Inactive Employees.

Employees who do not return to work within such period shall not become Continuing Business Employees unless otherwise agreed to by Purchaser.

(c) Employee Benefits Generally. From the Closing Date until the first anniversary thereof, Purchaser shall provide or cause to be provided the Continuing Business Employees with compensation and welfare benefits (excluding any severance or retiree medical benefits) that are not materially less favorable in the aggregate than those generally provided to similarly situated employees of Parent or its Affiliates immediately prior to the Closing. Except as may be specifically required by this Agreement or by applicable Law, Purchaser or its Affiliates shall not be obligated to provide any particular employee benefits to any Continuing Business Employee for any specific period of time. Nothing in this Agreement shall be deemed to limit the right of Purchaser or any of its Affiliates to terminate the employment of any Business Employee.

(d) Severance.

following the Closing Date, Purchaser shall, except as may otherwise be required by an Assumed Employment Agreement, provide or cause to be provided severance benefits and payments equal in value to those which such Continuing Business Employee would have received under such plan, policy or statement or other similar Contract had the employment of such Continuing Business Employee been terminated by Seller or its applicable Affiliate immediately prior to the Closing, and the amount of such severance benefits and payments shall be calculated in accordance with the terms of such applicable plan, policy or statement, Employment Agreement or other similar Contract in effect immediately prior to the Closing, taking into account the Continuing Business Employee’s period of employment prior through the Closing and with Purchaser or its Affiliates after the Closing.

(e) Preexisting Conditions; Deductibles; Credited Service. As of the date on which the Continuing Business Employees become eligible to participate in the applicable Purchaser benefit plans, Purchaser shall cause to be (i) waived all limitations as to preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to Continuing Business Employees under any welfare plan of Purchaser or its Subsidiaries or Affiliates in which such Continuing Business Employees may be eligible to participate after the Closing, to the extent that such conditions, exclusions and waiting periods would have been waived or satisfied under the corresponding welfare plan in which any such Continuing Business Employee participated immediately prior to the Closing, (ii) provided to each Continuing Business Employee credit for any co-payments and deductibles paid prior to the Closing, in respect of the calendar year in which the Closing Date occurs, in satisfying any applicable deductible or out-of-pocket requirements under any welfare plans of Purchaser or its Subsidiaries or Affiliates in which such Continuing Business Employees may be eligible to participate after the Closing in the calendar year in which the Closing Date occurs and (iii) provided to each Continuing Business Employee credit for purposes of eligibility, vesting and benefit accrual (other than with respect to any defined benefit pension plan) under each employee benefit plan, program or arrangement of Purchaser or its Subsidiaries or Affiliates in which such Continuing Business Employees are eligible to participate after the Closing for all service recognized by Seller under the corresponding Parent Benefit Plan; provided, however, that in no event shall the Continuing Business Employees be entitled to any credit to the extent that it would result in a duplication of benefits with respect to the same period of service.

(f) 401(k) Plan. Effective as of the Closing, Purchaser shall establish or cause to be established, and Seller shall reasonably cooperate with Purchaser to establish, participation by the Continuing Business Employees in Purchaser’s tax-qualified defined contribution plan or plans with a cash or deferred feature (the “Purchaser 401(k) Plan”) for the benefit of each Continuing Business Employee who, as of immediately prior to the Closing, was eligible to participate in a tax-qualified defined contribution plan maintained by Seller or its Affiliates (the “Seller 401(k) Plan”). Purchaser shall continue to make available and maintain the Purchaser 401(k) Plan for a period ending no earlier than the first anniversary of the Closing Date. As soon as practicable after the Closing Date, the Seller 401(k) Plan shall, to the extent permitted by Section 401(k)(10) of the Code, make distributions available to Continuing Business Employees, and the Purchaser 401(k) Plan shall accept any such distribution (including loans) as a rollover distribution if so directed by the Continuing Business Employee. The Parties agree to cooperate so as not to place any loan with respect to a Continuing Business Employee’s rollover account into default during the period from the Closing Date until the rollover is

completed; provided that such employee continues making loan repayments on a timely basis during such period in accordance with the established procedures of Seller and its Affiliates, as applicable.

(g) COBRA. Parent shall retain responsibility for continuation coverage under Sections 601 et seq. of ERISA and any state continuation coverage requirements (“COBRA Obligations”) to all Business Employees (and their qualified beneficiaries), for whom a “qualifying event” under COBRA occurs prior to the Closing. Purchaser shall be responsible for COBRA Obligations with respect to the Continuing Business Employees and their beneficiaries for whom a “qualifying event” under COBRA occurs at or after the Closing.

(h) WARN Act. Sellers shall not, by reason of its actions alone, at any time within the ninety (90)-day period immediately before the Closing Date, cause a Business Employee to incur an “employment loss” (as such term is defined in the WARN Act) without the consent of Purchaser (which will not be unreasonably withheld). Purchaser shall be solely responsible for and agrees to indemnify and hold harmless Seller and its Affiliates from and against any Liability under the WARN Act or any similar state Law to any Business Employee who is found to have suffered an “employment loss” under the WARN Act on or after the Closing Date as a result of the actions of Purchaser or any of its Affiliates, and any and all other Liabilities related to Purchaser’s or any of its Affiliates’ failure to comply with the WARN Act or any similar state Law, including attorneys’ fees, arising out of or resulting from the actions Purchaser or any of its Affiliates with respect to Business Employees and the WARN Act or any similar state Law, or their failure to serve sufficient notice pursuant to the WARN Act or any similar state Law.

(i) Flexible Spending Accounts. With respect to each Continuing Business Employee, effective as of the Closing, Purchaser shall establish, and, through December 31, 2013, Purchaser shall maintain or cause to be maintained flexible spending accounts for medical and dependent care expenses. Purchaser shall credit each such account at Closing with the amount credited as of the Closing Date under the comparable account maintained under the applicable Parent Benefit Plan from the beginning of the plan year in which the Closing occurs through the Closing Date. As soon as practicable after the Closing Date, (i) Seller shall pay, or cause to be paid, to Purchaser in cash the amount, if any, by which aggregate contributions made by Continuing Business Employees to Parent’s or its Affiliates’ flexible spending accounts exceeded the aggregate benefits provided to Continuing Business Employees as of the Closing, or (ii) Purchaser shall pay to Parent or its applicable Affiliate, as determined by Parent, in cash the amount, if any, by which aggregate benefits provided to Continuing Business Employees under Parent’s or its Affiliates’ flexible spending accounts exceeded the aggregate contributions made by Continuing Business Employees as of the Closing.

(j) To the extent permitted by the Parent Benefit Plans and the applicable equity and equity-based compensation awards of Parent, prior to the Closing, Parent shall take action to cause the equity and equity-based compensation awards of Parent held by Continuing Business Employees that are unvested as of the Closing to be amended to provide that such awards will vest (and if applicable, become exercisable and/or exchangeable) in full in the event that a Continuing Business Employee remains employed with Purchaser or an Affiliate for a period of 120 days following the Closing; provided, however, that Parent shall have the right to

maintain its customary provisions with regard to forfeiture of such awards, including forfeiture for violation of non-competition obligations; provided further, however, that the performance of services by Continuing Business Employees for Purchaser or an Affiliate with respect to the Business will in no event be treated as a violation of such non-competition obligations. Each Seller hereby agrees, on behalf of itself and its Affiliates, that any Business Employee who becomes a Continuing Business Employee pursuant to the transactions contemplated by this Agreement and remains employed by Purchaser or an Affiliate of Purchaser shall not be deemed to violate any non-competition, duty of loyalty, confidentiality or other restrictive covenant set forth in the Amended and Restated Agreement of Limited Partnership of BGC Holdings, dated as of March 31, 2008, as amended, solely as a result of such Business Employee becoming a Continuing Business Employee pursuant to the transactions contemplated by this Agreement and remaining employed by Purchaser or an Affiliate of Purchaser, and each Seller hereby, on behalf of itself and its Affiliates, irrevocably waives any right to enforce any such covenant against a Business Employee following the Closing if such covenant would be violated solely as a result of such Business Employee becoming a Continuing Business Employee pursuant to the transactions contemplated by this Agreement and remaining employed by Purchaser or an Affiliate of Purchaser.

(k) Purchaser shall make or cause to be made offers of consulting engagement to the Business Consultants on consulting terms and conditions substantially comparable (but not necessarily identical) to those terms and conditions of consulting applicable to the applicable Business Consultant immediately prior to the Closing.

(l) Except as set forth on Section 6.10(l) of the Seller Disclosure Letter, each Seller shall cause each loan from such Seller or an Affiliate of such Seller to a Business Employee to be forgiven on the date that is 120 days following the Closing Date, subject to such individual becoming a Continuing Business Employee hereunder and remaining employed by Purchaser or an Affiliate of Purchaser during such 120-day period; provided, however, any such loan may be forgiven prior to such 120^th day if the terms of any such loan require such earlier forgiveness.

(a) License. Each Seller hereby acknowledges and agrees that the Marks set forth on Section 2.1(a)(iv) of the Seller Disclosure Letter (such Marks collectively, the “Business Marks”) will, immediately following the Closing, be owned by Purchaser or one of its Affiliates. Accordingly, Sellers shall, and shall cause their Affiliates to, cease using the Business Marks as promptly as reasonably practicable but in any event within nine (9) months following the Closing. Effective as of the Closing, and subject to the terms and conditions set forth in this Section 6.12, Purchaser hereby grants to Parent and its Affiliates a non-exclusive, non-transferable, royalty-free license to use and display the Business Marks for the sole purpose of conducting the retained business of Parent and its Affiliates, consistent with past practice, following Closing.

(e) Reservation of Rights. All rights not expressly granted to Parent and its Affiliates under this Agreement are hereby reserved to Purchaser. Parent hereby disclaims any and all rights in, to or under the Business Marks, except to the extent expressly set forth in this Agreement.

Business Marks or with respect to any third party that Parent reasonably believes may make a claim that the use of the Business Marks infringes upon or otherwise violates any rights of any nature of such third party. Parent shall cooperate in all respects, as required by Purchaser, with regard to any action which Purchaser reasonably deems advisable either to protect the right of Purchaser in the Business Marks or to contest a claim by a third party that the use of the Business Marks infringes upon or otherwise violates any rights of any nature of such third party.

(g) Acknowledgements. Parent hereby acknowledges that (i) any and all goodwill and proprietary rights in the Business Marks (including any derivatives thereof) remain entirely vested in Purchaser from and after the Closing and (ii) Parent derives from this Agreement no rights in or to use any Business Mark from and after the Closing other than under and in accordance with the terms of this Agreement.

Section 6.13 Access to the Business. Purchaser shall, and shall cause its Affiliates and any successor in interest to the Business (such Affiliates, together with any successor in interest to the Business, the “Acquiring Affiliates”) to, permit each member of the Parent Group and each member of the Cantor Group to be customers of the fully electronic brokerage of the Business and to pay the lowest commission paid by any other customer of the Business, whether by volume, dollar amount or other applicable measurements (including on a price per volume basis for the most recently completed calendar quarter), regardless of whether such customer is paying a fixed commission or has agreed to trade a minimum amount of securities. For example, if a customer of the Business is paying a fixed commission of $x to Purchaser or any of the Acquiring Affiliates to trade U.S. Treasury Securities for the first calendar quarter of a year, and such customer trades y million of U.S. Treasury Securities during such calendar quarter, then each member of the Parent Group and each member of the Cantor Group shall be entitled to be customers of the fully electronic brokerage of the Business and to pay a commission equal to $x divided by y per million of U.S. Treasury Securities traded by such member during the second calendar quarter of such year, without an obligation by such member to pay the full fixed commission paid by such customer and without any minimum trading volume or other requirements.

In addition, Purchaser shall, and shall cause its Affiliates and the Acquiring Affiliates to, permit each member of the Parent Group and each member of the Cantor Group to receive any co-location and related installation, maintenance, support, remote access, and management of communication services, in each case to the extent that Purchaser or any Acquiring Affiliate offers or provides such services to any other customers of the Business following the Closing Date, at a cost to such member equal to any incremental out-of-pocket costs incurred by Purchaser or the Acquiring Affiliates in providing such member with such services (it being agreed that such costs shall not include any rent costs but may include the cost of utilities), provided that neither Purchaser nor the Acquiring Affiliates shall have any obligation to continue offering or providing any such services to customers of the Business following the Closing Date. Such co-location and related services shall be provided to each member of the Parent Group and each member of the Cantor Group (and each permitted successor thereto) on such terms and conditions as are generally applicable to receipt of such services by customers of the Business as of the Closing Date. The foregoing right to receive co-location and related services may not be sublicensed to, sublet to or otherwise enjoyed by any customer of any member of the Parent Group or the Cantor Group. Each member of the Parent

Group and each member of the Cantor Group may assign the foregoing right to receive co-location and related services in whole, without the prior written consent of Purchaser, only to a third party that acquires all or a majority of (1) in the case of assignment by a member of the Parent Group, the business of BGC Financial, L.P. (or any Affiliate of Parent that is a successor to such business) and (2) in the case of assignment by a member of the Cantor Group, the business of Cantor Fitzgerald & Co. (or any Affiliate of Cantor that is a successor to such business). The Parties agree that (y) except for the assignment rights expressly granted in the foregoing sentence, no member of the Parent Group and no member of the Cantor Group shall have any right to assign such right to receive co-location and related services, in whole or in part; and (z) in the event that such right is assigned by any member of the Parent Group or any member of the Cantor Group, all members of the Parent Group, or all members of the Cantor Group, as applicable, shall be deemed to have assigned such right in its entirety insofar as it relates to the rights granted to the Parent Group or the Cantor Group, as applicable, and no member of the Parent Group or the Cantor Group, as applicable, shall retain any right to receive such services.

Section 6.14 Clearing. From and after the Closing, Purchaser shall not, and shall cause the Acquiring Affiliates not to, with respect to the Business, (a) prevent customers of the Business from clearing their transactions with any member of the Cantor Group (including the Clearing Affiliate) or any member of the Parent Group, including by refusing to provide a service to such customer at the price or on terms offered by the Acquiring Affiliates to other similarly situated customers or (b) treat the Clearing Affiliate in an unreasonable, discriminatory or anti-competitive manner (including with respect to pricing and terms and including by refusing to deal with and boycotting the Clearing Affiliate) as compared to any other Person that provides the same or similar services as the Clearing Affiliate. In furtherance of the foregoing, with respect to the Business, if any Person provides clearing services to Purchaser or its Affiliates, Purchaser and such Affiliate shall execute an agreement with such Person providing that such Person and its Affiliates shall not (a) prevent customers of the Business from clearing their transactions with any member of the Cantor Group (including the Clearing Affiliate) or any member of the Parent Group, including by refusing to provide a service to such customer at the price or on terms offered by the Acquiring Affiliates to other similarly situated customers or (b) treat the Clearing Affiliate in an unreasonable, discriminatory or anti-competitive manner (including with respect to pricing and terms and including by refusing to deal with or boycotting the Clearing Affiliate) as compared to any other Person that provides the same or similar services as the Clearing Affiliate, and such agreement shall provide that the Clearing Affiliate shall be a third-party beneficiary of such provisions in the agreement. The Parties agree that this Section 6.14 is not intended to prohibit the Acquiring Affiliates from competing with any member of the Cantor Group or any member of the Parent Group in any business in the ordinary course of business.

Section 6.15 License Agreement Fees. If, due to a change in applicable Law, the royalty-free nature of the License Agreement would prohibit Purchaser or its Affiliates from charging fees or royalties to other market data customers, Purchaser shall endeavor to take such steps as are necessary to not prejudice Parent and its Affiliates’ rights under the License Agreement; provided that this Section 6.15 shall not require Purchaser to take any steps that would result in Purchaser or its Affiliates failing to comply with or violating any Law.

Section 6.16 Software License.

(a) From and after the Closing, Purchaser hereby grants to Parent, Sellers and their respective Affiliates (whether now existing or hereafter created or acquired), a non-exclusive, irrevocable, royalty-free, fully paid-up, world-wide right and license to use, reproduce, display, perform, distribute and modify all Software included within the Acquired Intellectual Property (the “Licensed Software”), with no restriction upon field of use. The rights granted pursuant to this Section 6.16(a) are collectively referred to herein as the “Software License.”

(b) Without limiting Section 6.16(a), Parent and its Affiliates shall have the full and unconditional right to alter, modify, prepare derivative works of, duplicate, reproduce and distribute the Licensed Software, including to alter or modify the source code thereof and to distribute such Licensed Software among any member of the Parent Group or the Cantor Group. Parent and its Affiliates may permit their respective suppliers, contractors, service providers and consultants to exercise any or all of the rights and licenses granted to Parent and its Affiliates solely at the direction of, and on behalf of, Parent or its Affiliates, as applicable.

Section 6.18 Section 16 Matters. Subject to applicable Law, Purchaser agrees that, upon the reasonable request of Parent from time to time and for the benefit of Parent and its Affiliates, Purchaser’s board of directors shall approve any issuance of Purchaser Shares to

Parent and its Affiliates pursuant to this Agreement for the purpose of exempting such issuances from the application of the “short-swing” trading rules under Section 16(b) of the Exchange Act pursuant to Rule 16b-3 under the Exchange Act; provided that Purchaser shall not be deemed to have represented or warranted that such exemption will apply.

BGC US hereby agrees that it shall guarantee all payment obligations of ELX through December 31, 2014 under the ELX Technology Contract; provided that such guarantee shall no longer be in effect upon the involuntary bankruptcy of ELX. Beginning three (3) years after the Closing Date, Purchaser or its Affiliate, as applicable, may at any time upon twenty-four (24) months’ prior written notice to Parent (such notice not to be given prior to the date that is three (3) years after the Closing Date), assign the ELX Technology Contract to BGC US or one its designated Affiliates. In the event of such assignment, Purchaser and its Affiliates shall, as a condition to such assignment and for no additional consideration: (a) transfer and convey to BGC US or one of its designated Affiliates, free and clear of all Liens, all Tangible Personal Property and (b) grant to BGC US or one of its designated Affiliates, a non-exclusive, irrevocable, royalty-free, fully paid-up, worldwide right and license to use any Software, in each of cases (a) and (b), then owned by Purchaser or its Affiliates to the extent used in connection with performance of Purchaser’s or its Affiliate’s obligations under the ELX Technology Contract; provided that, in the case of the right and license granted pursuant to clause (b), the field of use for such license shall be limited to use necessary to perform Parent’s and its Affiliates’ obligations under the ELX Technology Contract.

Section 6.23 Transition Services Matters. Between the date of this Agreement and the Closing Date, the Parties shall cooperate with each other to (a) identify any services (each, an “Additional Service”) currently provided by Sellers and their respective Affiliates to the Business that are not included as Transition Services in the form of Services Agreement

attached hereto as Exhibit A so as to provide to Purchaser the benefit of the Acquired Assets and the Continuing Business Employees to the same extent that the Business enjoyed such benefits as of immediately prior to the Closing; provided that none of services set forth on Section 6.23 of the Seller Disclosure Letter shall be an Additional Service; (b) determine the term that Sellers will provide such Additional Service to Purchaser after the Closing pursuant to the Services Agreement, which term shall be reasonable and shall not exceed twelve (12) months; (c) determine the cost to be charged to Purchaser in order to provide such Additional Service, with such cost to be equal to the cost incurred by Sellers and their Affiliates to provide such Additional Service to Purchaser and (d) reflect such Additional Services on the schedules to the Services Agreement to be executed by the Parties as of the Closing Date. The Parties agree that if they are not able to identify Additional Services to reflect in the Services Agreement, not able to determine the terms or costs for such Additional Services and/or not able to reflect such Additional Services on the schedule to the Services Agreement, then, at the Closing, they shall enter into the form of Services Agreement as attached as Exhibit A.

TAX MATTERS

Section 8.1 Liability for Taxes.

(a) Subject to Section 10.5(d) and Section 10.5(e), Parent shall be responsible for and shall indemnify Purchaser and its Affiliates (including the Acquired Subsidiaries) (the “Purchaser Tax Indemnitees”) from and against all Damages arising from or attributable to (i) Excluded Taxes (“Specified Taxes”), (ii) any breach of or inaccuracy in any representation or warranty contained in Section 4.22 (such Damages or breach and/or inaccuracy determined without respect to any materiality, Business Material Adverse Effect or similar term or

qualifications) and (iii) any breach of any covenant contained in Section 6.1(b)(xiv) or this Article VIII. Notwithstanding anything to the contrary contained in this Agreement, following the Closing, neither Purchaser nor any of its Affiliates, including the Acquired Subsidiaries, shall have any obligation to assert any claim or exercise any other right of recovery against any customer of Purchaser or any of its Affiliates (including the Acquired Subsidiaries) in respect of any sales or use Taxes.

(b) Subject to Section 10.5(d), Purchaser shall be responsible for and shall indemnify Parent, Sellers and their respective Affiliates (the “Seller Tax Indemnitees”) from and against all Damages arising from or attributable to (i) Taxes of or relating to the Business or the Acquired Subsidiaries (other than Excluded Taxes), (ii) any breach of any covenant contained in this Article VIII and (iii) the portion of Transfer Taxes for which Purchaser is liable pursuant to Section 8.5.

Section 8.2 Filing Responsibility.

(a) Parent shall prepare and file, or cause to be prepared and filed, when due all Tax Returns required to be filed by any Acquired Subsidiary prior to the Closing. All such Tax Returns shall be prepared and filed in a manner that is consistent with prior practice, if any, except as required by applicable law. Parent shall pay or cause to be paid all Taxes due and payable in respect of all such Tax Returns. In the case of any Tax Return required to be prepared and filed by Parent pursuant to this subsection for which the position taken with respect to any Tax Item is reasonably likely to increase the Taxes of any Purchaser Tax Indemnitee with respect to any taxable period or portion thereof beginning after the Closing Date, Parent shall deliver a draft of such Tax Return to Purchaser for its review at least twenty (20) Business Days prior to the Due Date, and Parent shall consider in good faith any comments received from Purchaser.

(b) Purchaser shall, except to the extent that the filing of such Tax Returns is the responsibility of Parent under Section 8.2(a), prepare and file, or cause to be prepared and filed, all Tax Returns required to be filed by any Acquired Subsidiaries. In the case of any Tax Return required to be prepared and filed by Purchaser pursuant to this subsection for which any Taxes are the responsibility of Parent under Section 8.1(a), Purchaser shall deliver a draft of such Tax Return to Parent for its review at least twenty (20) Business Days prior to the Due Date and shall provide Parent with Purchaser’s calculation, in reasonable detail, of Parent’s share of the Taxes with respect to such Tax Return (determined in the case of a Straddle Period in accordance with Section 8.2(c)); provided, however, that such drafts of any such Tax Return and such calculations of Parent’s share of the Taxes with respect to such Tax Return shall be subject to Parent’s review and approval, which approval shall not be unreasonably withheld, conditioned or delayed. If Parent disputes any Tax Item on such Tax Return or Purchaser’s calculation of Parent’s share of the Taxes with respect to such Tax Return, Parent shall notify Purchaser (by written notice within five (5) days of receipt of Purchaser’s calculation) of such disputed item (or items) and the basis for its objection. If Parent does not object by written notice within such period, Purchaser’s calculation of Parent’s share of the Taxes with respect to such Tax Return shall be deemed to have been accepted and agreed upon, and final and conclusive, for all purposes hereof. Parent and Purchaser shall act in good faith to resolve any such dispute prior to the Due Date. If Parent and Purchaser cannot resolve any disputed item, the item in question shall be resolved by the Accountant in a manner consistent with the standards set forth in Section

3.7(c) as promptly as practicable. No later than five (5) days prior to the filing of such Tax Return, Parent shall pay Purchaser in immediately available funds the amount of Parent’s share of the Taxes with respect to such Tax Return determined pursuant to this Section 8.2(b). Subject to the preceding sentence, Purchaser shall pay or cause to be paid all Taxes due and payable in respect of all Tax Returns required to be prepared by Purchaser pursuant to this subsection. If the Accountant has not finalized its conclusion in respect of any disputed item prior to the Due Date, Purchaser shall (i) file such Tax Return in the form initially provided to Parent, (ii) amend such Tax Return if the dispute is subsequently resolved in favor of Parent, and (iii) pay Parent in immediately available funds the amount of any excess of (x) the amount paid by Parent to Purchaser pursuant to this Section 8.2(b) and (y) the amount of Parent’s share of the Taxes with respect to such Tax Return as finally determined by the Accountant.

(c) In order to apportion appropriately any Taxes relating to a Straddle Period between the portion of such Straddle Period ending on and including the Closing Date and the portion of such Straddle Period beginning after the Closing Date, the Parties shall, to the extent permitted under applicable law, elect with the relevant Tax authority to treat for all Tax purposes the Closing Date as the last day of a taxable period. In the case of any other Taxes for a Straddle Period for which such election to close the taxable period is not permitted, the portion of such Taxes that are allocable to the portion of the Straddle Period ending on and including the Closing Date shall be: (i) in the case of ad valorem or similar Taxes that are imposed on a periodic basis, deemed to be the amount of such Taxes for the entire period (or, in the case of such Taxes determined on an arrears basis (such as real property Taxes), the amount of such Taxes for the immediately preceding period) multiplied by a fraction the numerator of which is the number of days in the Straddle Period ending on and including the Closing Date and the denominator of which is the number of days in the entire relevant Straddle Period; and (ii) in the case of Taxes not described in (i) (such as Taxes that are either (x) based upon or related to income, receipts or premiums, or (y) imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible)), deemed equal to the amount that would be payable if the taxable period ended on and included the Closing Date.

Section 8.3 Cooperation and Exchange of Information.

(a) The Parties and Cantor shall cooperate with each other and furnish or cause to be furnished to each other, upon request, as promptly as practicable, such information (including access to books and records) and assistance relating to the Business or the Acquired Subsidiaries as is reasonably requested for the filing of any Tax Returns, and the preparation and conduct of any Tax Proceeding. Anything to the contrary in this Agreement notwithstanding, Parent shall not be required to provide any person with any Tax Return (or copy thereof) of Parent or any consolidated, combined or unitary group that includes Parent or any member of the Parent Group.

(b) Cantor, Parent and Purchaser shall, and shall cause their respective Subsidiaries to, cooperate in the preparation of all Tax Returns that are required to be filed after the Closing Date relating to Pre-Closing Tax Periods or to Straddle Periods.

(c) Purchaser shall promptly notify Parent upon receipt by Purchaser or any of its Subsidiaries of notice of any claim, assessment or dispute relating to any Tax Proceeding for

which Parent has liability pursuant to Section 8.1(a) and shall promptly forward to Parent any written communications received from any Governmental Authority in connection with any such Tax Proceeding; provided, however, that a failure by Purchaser to give such notice will not affect the Purchaser Tax Indemnitees’ rights to indemnification pursuant to Section 8.1(a) unless and solely to the extent Parent is materially prejudiced as a consequence of such failure.

(d) Parent may elect to control, contest, resolve and defend, at Parent’s sole expense and with the participation of Purchaser, any Tax Proceeding relating to Taxes of any Acquired Subsidiary for a Pre-Closing Tax Period. If Parent desires to elect to control any such Tax Proceeding, Parent shall, within ten (10) days of receipt of the notice of the Tax Proceeding from Purchaser, notify Purchaser in writing of its intent to do so. If Parent timely elects to control any such Tax Proceeding, then Parent shall have the right to determine whether, when and on what terms to settle or dispose of such Tax Proceeding; provided, however, that Parent shall not settle or dispose of such Tax Proceeding if such settlement or disposition could affect the Liability for Taxes of any Purchaser Tax Indemnitee without the consent of Purchaser, which consent shall not be unreasonably withheld, conditioned or delayed. If Parent does not elect to control a Tax Proceeding which it is entitled to control pursuant to this subsection (or, after assuming control, Parent fails to reasonably pursue such Tax Proceeding), any of the Purchaser Tax Indemnitees may, without affecting its or any of the other Purchaser Tax Indemnitees’ rights to indemnification under Section 8.1(a), assume and control such Tax Proceeding; provided, however, that if the settlement or disposition of such Tax Proceeding would affect the Liability for Taxes of any Seller Tax Indemnitee, such Purchaser Tax Indemnitee may not settle such Tax Proceeding without the consent of Parent, which consent shall not be unreasonably withheld, conditioned or delayed. Purchaser shall control, contest, resolve and defend, at Purchaser’s sole expense and with the participation of Parent at its sole expense, any Tax Proceeding relating to Taxes of any Acquired Subsidiary for a Straddle Period. Purchaser shall have the right to determine whether, when and on what terms to settle or dispose of any such Tax Proceeding; provided, however, that Purchaser shall not settle or dispose of any such Tax Proceeding if such settlement or disposition could affect the Liability for Taxes of any Seller Tax Indemnitee, without the consent of Parent, which consent shall not be unreasonably withheld, conditioned or delayed.

Section 8.4 Tax Sharing Agreements. Notwithstanding anything herein or in any other agreement to the contrary, all Liabilities between Parent or any of its Affiliates (other than the Acquired Subsidiaries), on the one hand, and the Acquired Subsidiaries, on the other hand, under any Tax allocation or Tax sharing agreement to which an Acquired Subsidiary is a party in effect prior to the Closing Date (other than this Agreement) shall cease and terminate as of the Closing Date.

Section 8.5 Transfer Taxes. Parent will be responsible for preparing and timely filing (and Purchaser will cooperate with Parent in preparing and filing) any Tax Returns required with respect to any Transfer Taxes. Parent will provide to Purchaser a true copy of each such Tax Return as filed and evidence of the timely filing thereof. Parent and Purchaser shall share equally the Liability for any Transfer Taxes and the costs for preparing any Tax Returns for Transfer Taxes. Each of Parent and Purchaser shall (a) use commercially reasonable efforts to minimize the amount of Transfer Taxes and (b) jointly control any Tax Proceeding relating to Transfer Taxes.

Section 8.6 Survival. All rights and obligations under this Article VIII shall survive the Closing Date and continue until after the expiration of all applicable statutes of limitation (including extensions thereof); provided, however, that in the event written notice of any bona fide claim for indemnification under this Article VIII shall have been given in accordance herewith within the applicable survival period, the rights and obligations that are the subject of such claim for indemnification shall survive with respect to such claim until such time as such claim is fully and finally resolved. The representations and warranties contained in Section 4.22 shall survive until after the expiration of all applicable statutes of limitations, which shall include the statute of limitations with respect to taxable years beginning after the Closing Date through and including the taxable year in which the fifteenth (15th) anniversary of the Closing Date occurs (including extensions thereof).

Section 8.7 Tax Treatment of Payments. Each member of the Parent Group, Sellers, the Acquired Subsidiaries, Purchaser, and their respective Affiliates shall treat any and all payments under this Article VIII, Section 3.8 or Article X as an adjustment to purchase price for all Tax purposes.

Section 8.8 Treatment as Asset Sale. The Parties acknowledge that for federal income Tax purposes, the sale of the equity of each Acquired Subsidiary pursuant to this Agreement is intended to be treated as a sale of the assets of such Acquired Subsidiary (and an assumption by Purchaser of the liabilities of such Acquired Subsidiary).

ARTICLE IX

TERMINATION

Section 9.1 Termination. This Agreement may be terminated and the transactions contemplated hereby may be abandoned at any time prior to the Closing:

(a) by the mutual written consent of Purchaser and Parent;

(b) by either Purchaser or Parent, upon written notification of the non-terminating Party by the terminating Party, if any permanent Governmental Order prohibiting consummation of the transactions contemplated by this Agreement shall have been issued and shall have become final and non-appealable (except that a final, permanent Governmental Order preventing the Closing as a result of an action brought by a Governmental Authority under any antitrust, competition or trade regulation Law need not be non-appealable so long as Purchaser has complied with its obligations set forth in Section 6.4); provided, however, that a Party shall not have the right to terminate this Agreement pursuant to this Section 9.1(b) if the failure by such Party or of any of its Affiliates to perform any of its material covenants or obligations under this Agreement has been the cause of, or has resulted in, such Governmental Order;

(c) by either Purchaser or Parent, if the Closing has not occurred by the date that is twelve (12) months after the date hereof (the “Outside Date”); provided, however, that if, as of twelve (12) month anniversary of the date hereof, either the condition set forth in Section 7.1(a) or Section 7.1(b) (solely with respect to any Governmental Order under any antitrust or

competition Law) has not been satisfied or waived, but all other conditions to the Closing set forth in Article VII have been satisfied or mutually waived (other than those conditions which by their nature can only be satisfied at or immediately prior to the Closing, which conditions would be satisfied if the Closing Date were such twelve (12) month anniversary of the date hereof), then the Outside Date shall be extended until both the conditions set forth in Section 7.1(a) and Section 7.1(b) (solely with respect to any Governmental Order under any antitrust or competition Law) have been satisfied; provided, further, that neither Purchaser nor Parent shall have the right to terminate this Agreement pursuant to this Section 9.1(c) if (i) its failure to perform any of its material covenants or obligations under this Agreement has been the cause of, or has resulted in, the failure of the transactions contemplated by this Agreement to occur on or before such date or (ii) a Governmental Authority has brought an action under any antitrust, competition or trade regulation Law, and that action has not yet resulted in a final Governmental Order preventing the Closing;

(d) by Parent, if Purchaser shall have breached any of its representations, warranties, covenants or agreements contained in this Agreement that would give rise to the failure of a condition set forth in Section 7.3(a) or Section 7.3(b), which breach has not been cured within sixty (60) days after the giving of written notice by Parent to Purchaser specifying such breach, or cannot be cured by the earlier of (x) sixty (60) days after the giving of written notice by Parent to Purchaser specifying such breach or (y) the Outside Date; or

(e) by Purchaser, if any Seller or Cantor shall have breached any of its representations, warranties, covenants or agreements contained in this Agreement that would give rise to the failure of a condition set forth in Section 7.2(a) or Section 7.2(b), which breach has not been cured within sixty (60) days after the giving of written notice by Purchaser to Parent specifying such breach, or cannot be cured by the earlier of (x) sixty (60) days after the giving of written notice by Purchaser to Parent specifying such breach or (y) the Outside Date.

Section 9.2 Effect of Termination. If this Agreement is terminated, no party hereto (or any of its Affiliates, directors, officers, representatives or agents) will have any Liability to any other party to this Agreement, except for any Liability arising out of any knowing or willful breach of this Agreement prior to such termination and except for the obligations set forth in Sections 6.2(b) and 6.6(a) and Article XI, which shall survive termination.

ARTICLE X

INDEMNIFICATION

Section 10.1 Survival of Representations and Warranties and Covenants.

(a) Except as otherwise provided in Section 8.6, the right to commence any claim with respect to the representations and warranties set forth herein shall survive until the date that is twelve (12) months after the Closing Date; provided that the right to commence any claim with respect to the representations and warranties contained in (i) Section 4.11 (Employee Benefit Plans) will survive until the expiration of the applicable statute of limitations and (ii) Section 4.1(a) (Organization and Good Standing), Sections 4.2(a) and (b) (Acquired

Subsidiaries), Section 4.3 (Authorization; Binding Obligations), Section 4.8 (Transactions with Affiliates), Section 4.10(a) and (b) (Title), Section 5.1 (Organization and Good Standing) and Section 5.3 (Authorization; Binding Obligations) will survive indefinitely.

(b) The covenants and agreements that contemplate actions to be taken or not taken or obligations in effect after the Closing shall survive in accordance with their terms. This Section 10.1 shall not limit any covenant or agreement of the parties contained in this Agreement which by its terms contemplates performance after the Closing, and shall not extend the applicability of any covenant or agreement of the parties contained in this Agreement which by its terms relates only to a period between the date hereof and the Closing, except that the right to commence any claim with respect to any such covenant or agreement which by its terms relates only to a period between the date hereof and the Closing shall survive until the date that is twelve (12) months after the Closing Date.

(c) Notwithstanding Section 10.1(a) and Section 10.1(b), in the event written notice of any bona fide claim for indemnification under Section 10.2(a), Section 10.2(b), Section 10.3(a) or Section 10.3(b) shall have been given in accordance herewith within the applicable survival period setting forth in reasonable detail the legal and factual basis for such claim, the indemnification claim shall survive until such time as such claim is fully and finally resolved. Neither Purchaser nor Sellers shall have any liability pursuant to this Agreement with respect to any claim first asserted in connection with any indemnification claim for a breach of representation, warranty, covenant or agreement asserted after the survival period specified for such representation, warranty, covenant or agreement in Section 8.6, Section 10.1(a) or Section 10.1(b), as applicable.

Section 10.2 Indemnification of Purchaser. Subject to Section 10.5, from and after the Closing Date, each Seller shall, jointly and severally, indemnify, defend, save and hold harmless Purchaser and its Affiliates (including the Acquired Subsidiaries), each of their respective officers, directors, employees, agents and representatives, and each of the heirs, executors, successors and assigns of the foregoing (collectively, the “Purchaser Indemnified Parties”), from and against (whether in connection with a Third Party Claim or a direct claim) any and all Damages to the extent resulting from, arising out of or relating to:

(a) any breach by any Seller or Cantor of any representation or warranty under this Agreement or in any certificate or document delivered pursuant hereto (other than any representation or warranty set forth in Section 4.22 (Taxes)), such breach and Damages determined without regard to any Business Material Adverse Effect or materiality qualification (except for (i) the lists of information required to be set for the pursuant to the representations and warranties in Section 4.11 (Employee Benefit Plans), 4.15 (Real Property), 4.17 (Licenses and Permits), and Section 4.19 (Certain Contracts), and (ii) Section 4.9(b)(ii) (Financial Statements), Section 4.18 (Absence of Certain Changes), in each case, as to which such breaches and Damages shall be determined with regard to any Business Material Adverse Effect or materiality qualification contained therein);

(b) the failure by any Seller or Cantor to perform timely any of its covenants or agreements contained in this Agreement or in any agreement, certificate, document, or other instrument delivered pursuant hereto; and

(a) any breach by Purchaser of any representation or warranty under this Agreement or in any certificate or document delivered pursuant hereto (such breach and Damages determined without regard to any Purchaser Material Adverse Effect, or materiality or similar term or qualification);

(b) the failure by Purchaser to perform timely any of its covenants or agreements contained in this Agreement or in any agreement, certificate, document, or other instrument delivered pursuant hereto; and

Section 10.4 Claims.

(a) Third Party Claims. Upon receipt by an Indemnified Party of notice of any action, suit, proceedings, audit, claim, demand, investigation or assessment made or brought by an unaffiliated third party (a “Third Party Claim”) with respect to a matter for which such Indemnified Party is indemnified under this Article X which has or is expected to give rise to a claim for Damages, the Indemnified Party shall promptly (but in any event within ten (10) Business Days of receipt of such Third Party Claim), in the case of a Purchaser Indemnified Party, notify Parent, and in the case of a Seller Indemnified Party, notify Purchaser (Parent or Purchaser, as the case may be, the “Indemnifying Party”), in writing, indicating the nature of such Third Party Claim and the basis therefor; provided, however, that any delay or failure by the Indemnified Party to give notice to the Indemnifying Party shall relieve the Indemnifying Party of its obligations hereunder only to the extent, if at all, that it is materially prejudiced by reason of such delay or failure. Such written notice (a “Claim Notice”) shall include (i) the facts and circumstances giving rise to such claim for indemnification, to the extent then known by the Indemnified Party and copies of all material written evidence thereof to the extent available, (ii) the nature of the Damages suffered or incurred or expected to be suffered or incurred, to the extent then known by the Indemnified Party, (iii) a reference to the provisions of this Agreement in respect of which such Damages have been suffered or incurred or are expected to be suffered or incurred and (iv) the amount of Damages actually suffered or incurred, to the extent then known by the Indemnified Party. The Indemnifying Party shall have thirty (30) days after receipt of the Claim Notice to elect, at its option, to assume and control the defense of, at its own expense and by its own counsel, any such Third Party Claim and shall be entitled to assert any and all defenses available to the Indemnified Party to the fullest extent permitted by applicable law; provided that, prior to the Indemnifying Party assuming and controlling such defense, it shall first confirm to the Indemnified Party in writing that, assuming the facts then presented to

the Indemnifying Party by the Indemnified Party being true, the Indemnifying Party shall indemnify the Indemnified Party for any such Damages to the extent resulting from, or arising out of, such Third Party Claim; provided, further, that, if the Indemnifying Party assumes such defense and, in the course of defending such Third Party Claim, (x) the Indemnifying Party discovers that the facts presented at the time the Indemnifying Party acknowledged its indemnification obligation in respect of such Third Party Claim were not true and (y) such untruth provides a reasonable basis for asserting that the Indemnifying Party does not have an indemnification obligation in respect of such Third Party Claim, then (A) the Indemnifying Party shall not be bound by such acknowledgment, (B) the Indemnifying Party shall promptly thereafter provide the Indemnified Party written notice of its assertion that it does not have an indemnification obligation in respect of such Third Party Claim and (C) the Indemnified Party shall have the right to assume the defense of such Third Party Claim (it being agreed that all costs and expenses in conducting such defense prior to the date that the Indemnified Party shall have the ability to assume the defense, including costs and expenses of counsel, shall be the responsibility of the Indemnifying Party and not the Indemnified Party). If the Indemnifying Party shall undertake to compromise or defend any such Third Party Claim, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party agrees to, and to cause its Affiliates to, cooperate with the Indemnifying Party and its counsel in the compromise of, or defense against, any such Third Party Claim, including by furnishing non-privileged books and records, personnel and witnesses, as appropriate for any defense of such Third Party Claim; provided, however, that the Indemnifying Party shall not settle, compromise or discharge, or admit any liability with respect to, any such Third Party Claim without the prior written consent of the Indemnified Party (which consent will not be unreasonably withheld or delayed) unless the relief consists solely of money damages and includes a provision whereby the plaintiff or claimant in the matter releases the Purchaser Indemnified Parties or Seller Indemnified Parties, as applicable, from all liability with respect thereto. Notwithstanding an election to assume the defense of such action or proceeding, the Indemnified Party shall have the right to employ separate counsel and to participate in the defense of such action or proceeding, and the Indemnifying Party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the Indemnified Party shall have determined in good faith after consultation with counsel that an actual or potential conflict of interest makes representation by the same counsel or the counsel selected by the Indemnifying Party inappropriate or (ii) the Indemnifying Party shall have authorized in writing the Indemnified Party to employ separate counsel at the Indemnifying Party’s expense. In any event, the Indemnified Party and Indemnifying Party and their counsel shall cooperate in the defense of any Third Party Claim subject to this Article X and keep such Persons informed of all developments relating to any such Third Party Claims, and provide copies of all relevant correspondence and documentation relating thereto. All costs and expenses incurred in connection with the Indemnified Party’s cooperation shall be borne by the Indemnifying Party. In any event, the Indemnified Party shall have the right at its own expense to participate in the defense of such asserted liability. If the Indemnifying Party receiving such notice of Third Party Claim does not elect to defend, or does not defend, such Third Party Claim, the Indemnified Party shall have the right, in addition to any other right or remedy it may have hereunder, at the Indemnifying Party’s expense, to defend such Third Party Claim; provided, however, that (i) the Indemnified Party’s defense of or participation in the defense of any such Third Party Claim shall not in any way diminish or lessen the obligations of the Indemnifying Party under this Article X; and (ii) the Indemnified Party shall not settle, compromise or discharge, or admit any liability with respect to, any such Third Party Claim without the written consent of the Indemnifying Party (which consent will not be unreasonably withheld or delayed).

(b) Direct Claims. As promptly as is reasonably practicable (but in any event, within ten (10) Business Days) after becoming aware of a claim for indemnification under this Agreement not involving a Third Party Claim, the Indemnified Party shall provide a Claim Notice to the Indemnifying Party of such claim. Each Party hereto also agrees that any direct claim which such Party may bring against any other Party hereto under the provisions of this Agreement shall be governed exclusively by the provisions of this Article X, other than Section 10.4(a).

Section 10.5 Limitations.

(a) To avoid any duplicative recovery, in no event shall Sellers or Purchaser be required to provide indemnification to any Purchaser Indemnified Party or Seller Indemnified Party, respectively, pursuant to Section 10.2 or 10.3 for any amount that is included in the final Adjustment Amount.

(b) In no event shall (i) Sellers be required to provide indemnification to any Purchaser Indemnified Party for any single claim or aggregated claims arising out of substantially the same events or circumstances under Section 8.1(a) or 10.2 or (ii) Purchaser be required to provide indemnification to any Seller Indemnified Party for any single claim or aggregated claims arising out of substantially the same events or circumstances under Section 8.1(b) or 10.3, in each of cases (i) and (ii), unless the amount of such claim or aggregated claims arising out of substantially the same events or circumstances is in excess of fifty thousand dollars ($50,000) (“De Minimis Claims”), in which event, subject to the Threshold, the applicable Indemnifying Party shall be required to pay for all Damages back to the first dollar of any such claims; provided, however, that the limitation set forth in this Section 10.5(b) shall not apply to any breach of the covenants or obligations set forth in Section 3.3 (Closing Purchase Price), Section 3.7 (Post-Closing Adjustment) or Section 3.8 (Earn-Out).

(c) Sellers shall not be liable for any amounts for which Purchaser Indemnified Parties are otherwise entitled to indemnification pursuant to Section 10.2(a) until the aggregate amount of all Damages exceeds, on a cumulative basis, seven million five hundred thousand dollars ($7,500,000) (the “Threshold”), and then the Purchaser Indemnified Parties shall be entitled to indemnification pursuant to Section 10.2(a) for all of their Damages (excluding any Damages with respect to De Minimis Claims) in excess of such Threshold; provided, however, that the limitation set forth in this Section 10.5(c) shall not apply to any breach of the representations and warranties set forth in Section 4.1(a) (Organization and Good Standing), Section 4.2(a) and (b) (Acquired Subsidiaries), Section 4.3 (Authorization; Binding Obligations), Section 4.5 (Approvals), Section 4.7(b) (Compliance with Law), Section 4.8 (Transactions with Affiliates), Section 4.10(a) and (b) (Title), Section 4.13 (No Brokers or Finders) or Section 4.24 (Sufficiency of Assets) and Damages related thereto shall not be included in the calculation of the Threshold. Purchaser shall not be liable for any amounts for which Seller Indemnified Parties are otherwise entitled to indemnification pursuant to Section 10.3(a) until the aggregate amount of all Damages exceeds, on a cumulative basis, the Threshold, and then the Seller Indemnified Parties shall be entitled to indemnification pursuant to Section

10.3(a) for all of their Damages (excluding any Damages with respect to De Minimis Claims) in excess of the Threshold; provided, however, that the limitation set forth in this Section 10.5(c) shall not apply to any breach of the representations and warranties set forth in Section 5.1 (Organization and Good Standing), Section 5.3 (Authorization; Binding Obligations), Section 5.5 (Approvals) or Section 5.10 (No Brokers or Finders) and Damages related thereto shall not be included in the calculation of the Threshold.

(d) In no event shall Sellers’ aggregate liability pursuant to Section 8.1(a) and Section 10.2 (other than any liability thereunder for the Seller Excluded Items (and Damages related thereto shall not be included in the calculation of the Cap)) exceed an amount equal to one hundred million dollars ($100,000,000) (the “Cap”). “Seller Excluded Items” shall mean (i) any breach of the representations and warranties set forth in Section 4.1(b) (Organization and Good Standing), Section 4.2(a) and (b) (Acquired Subsidiaries), Section 4.3 (Authorization; Binding Obligations), Section 4.8 (Transactions with Affiliates), Section 4.10(a) and (b) (Title) or Section 4.13 (No Brokers or Finders), (ii) indemnification pursuant to Section 10.2(c), (iii) any breach of any covenant or agreement to be performed at or following the Closing and (iv) any fraud. In no event shall Purchaser’s aggregate liability pursuant to Section 8.1(b) and Section 10.3 (other than any liability thereunder for the Purchaser Excluded Items (and Damages related thereto shall not be included in the calculation of the Cap)) exceed an amount equal to the Cap. “Purchaser Excluded Items” shall mean (i) any breach of the representations and warranties set forth in Section 5.1 (Organization and Good Standing), Section 5.3 (Authorization; Binding Obligations) or Section 5.10 (No Brokers or Finders), (ii) indemnification pursuant to Section 10.3(c), (iii) any breach of any covenant or agreement to be performed at or following the Closing and (iv) any fraud.

(e) In no event shall Sellers’ aggregate liability pursuant to Section 8.1(a) and Section 10.2 (including any liability thereunder for the Seller Excluded Items) exceed an amount equal to five hundred million dollars ($500,000,000) (the “Aggregate Liability Cap”); provided, however, that the limitation set forth in this sentence shall not apply to any breach of the covenants or obligations set forth in Section 3.7 (Post-Closing Adjustment). In no event shall Purchaser’s aggregate liability pursuant to Section 8.1(b) and Section 10.3 (including any liability thereunder for the Purchaser Excluded Items) exceed an amount equal to the Aggregate Liability Cap; provided, however, that the limitation set forth in this sentence shall not apply to any breach of the covenants or obligations set forth in Section 3.3 (Closing Purchase Price), Section 3.7 (Post-Closing Adjustment) or Section 3.8 (Earn-Out).

(f) The Purchaser Indemnified Parties shall have a right to set off any payment in respect of an indemnification claim of any Purchaser Indemnified Party under Article VIII and this Article X against any unissued Earn-Out Issuance (with such Purchaser Shares being valued at the Current Market Price as of the applicable date that Purchaser is required to make the Earn-Out Issuance subsequent to such time as a Purchaser Indemnified Party is entitled to payment pursuant to Article VIII or this Article X); it being agreed that the Purchaser Indemnified Party and the applicable Seller may agree to settle such set off in cash instead of Purchaser Shares. Such right of set-off shall be the sole and exclusive source of funds to satisfy any such indemnification claim other than in respect of any breach of the covenants or obligations set forth in Section 3.3 (Closing Purchase Price) and Section 3.7 (Post-Closing Adjustment); except in the event that such right of set-off is insufficient to fully indemnify the Purchaser Indemnified Parties with respect to claims for indemnification with respect to the Seller Excluded Items.

(g) Purchaser and Seller acknowledge and agree that, following the Closing, other than with respect to fraud, the indemnification provisions of Section 8.1, Section 10.2 and Section 10.3 shall be the sole and exclusive monetary remedies of Seller and Purchaser, respectively, for any Damages (including any Damages from claims for breach of contract, warranty, tortious conduct (including negligence) or otherwise and whether predicated on common law, statute, strict liability, or otherwise) that each party may at any time suffer or incur, or become subject to, as a result of or in connection with this Agreement, or the transaction contemplated by this Agreement, including any breach of any representation or warranty in this Agreement by any party, or any failure by any party to perform or comply with any covenant or agreement that, by its terms, was to have been performed, or complied with, under this Agreement.

(h) Except for amounts where the sole and exclusive source of funds shall be the right of set-off as set forth in Section 10.5(f), amounts payable by the Indemnifying Party to the Indemnified Party in respect of any Damages for which such party is entitled to indemnification hereunder (“Indemnity Payments”) shall be paid in immediately available funds within twenty (20) Business Days after the later of the (i) the receipt of a written request from the party entitled to such Indemnity Payment and (ii) date of payment of the amount that is the subject of the Indemnity Payment by the party entitled to receive the Indemnity Payment, except to the extent contested by the Indemnifying Party. All such Indemnity Payments shall be made to the designated account of, and in the manner specified in writing by, the party entitled to such Indemnity Payments.

Section 10.6 Insurance. Notwithstanding anything herein to the contrary, Damages shall be net of any insurance or other recoveries actually received by the Indemnified Party or its Affiliates in connection with the facts giving rise to the right of indemnification. The Indemnified Party shall use, and cause its Affiliates to use, commercially reasonable efforts to seek full recovery under all insurance and indemnity provisions covering such Damages to the same extent as it would if such Damages were not subject to indemnification hereunder. If an Indemnified Party shall have used its reasonable efforts to recover any amounts recoverable under insurance policies and shall not have recovered the applicable Damages in full within one hundred twenty (120) days, the Indemnifying Party shall promptly pay upon written request the amount with interest accrued thereon, by which such Damages exceeds the amounts actually recovered.

Section 10.7 Additional Limitations on Damages.

(a) In no event shall any Indemnified Party have any Liability for (i) Damages computed on a multiple of earnings, book value or similar basis, (ii) special, speculative, indirect or consequential Damages or lost profits to the extent not the direct and reasonably foreseeable consequence of the relevant breach or (iii) punitive damages, except in the case of clauses (i) and (ii), to the extent awarded against an Indemnified Party in connection with a Third Party Claim.

(b) In no event shall any Party be indemnified against any Damage arising out of a breach of any representation and warranty or covenant or agreement of the other Party, if the first Party had Knowledge at or before the (i) date hereof, of such breach or the facts underlying such breach, (ii) Closing, of such breach or the facts underlying such breach and such Party could have terminated this Agreement as a result of such breach in accordance with Section 9.1(d) or Section 9.1(e), as applicable, or (iii) Closing, of such breach or the facts underlying such breach and such party did not notify the other Party of such breach.

Section 10.8 Tax Indemnification. Other than Section 10.5 and 10.7, the provisions of this Article X shall not apply to indemnification with respect to matters relating to Taxes, which shall be governed exclusively by Article VIII.

Section 10.9 Mitigation. Each of the Parties agrees to use its commercially reasonable efforts to mitigate its respective Damages upon and after becoming aware of any event or condition that would reasonably be expected to give rise to any Damages that are indemnifiable hereunder. Upon making any payment to the Indemnified Party for any indemnification claim pursuant to this Article X, the Indemnifying Party shall be subrogated, to the extent of such payment, to any rights which the Indemnified Party may have against any third parties (but specifically excluding any right of recovery against any customer other than any Retained Claim) with respect to the subject matter underlying such indemnification claim, and the Indemnified Party shall assign any such rights to the Indemnifying Party.

Section 11.2 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware applicable to agreements made and to be performed entirely within such State, without regard to the conflict of laws principles of such State.

Section 11.3 Jurisdiction; Venue; Consent to Service of Process.

(a) Each party hereto hereby consents to submit to the exclusive jurisdiction of the Chancery Court in the State of Delaware in connection with any action or proceeding instituted relating to this Agreement. Each of the parties consents to the jurisdiction of such court (and of the appropriate appellate courts) in any such action or proceeding and hereby waives (x) any objection to venue laid therein and (y) any right to remove such action or proceeding to a

federal court. In addition, each of the parties hereto irrevocably and unconditionally waives and agrees not to assert by way of motion, as a defense or otherwise (i) any claim that it is not subject to the jurisdiction of the above court, (ii) that its property is exempt or immune from attachment or execution in any such action or proceeding in the above-named courts, (iii) that such action or proceeding is brought in an inconvenient or improper forum, (iv) that such action or proceeding should be transferred or removed to any court other than the above-named court, or should be stayed by reason of the pendency of some other proceeding in any other court other than the above-named court, or that this Agreement or the subject matter hereof may not be enforced in or by such court. Each of the parties hereto hereby agrees not to commence any such action or proceeding other than before the above-named court. Each of the parties hereto also hereby agrees that any final and unappealable judgment against a party in connection with any such action or proceeding shall be conclusive and binding on such party and that such judgment may be enforced in any court of competent jurisdiction, either within or outside of the United States. A certified or exemplified copy of such award or judgment shall be conclusive evidence of the fact and amount of such award or judgment. The foregoing consent to jurisdiction shall not (a) constitute submission to jurisdiction in the State of Delaware for any purpose except with respect to any action or proceeding resulting from, relating to or arising out of this Agreement or (b) be deemed to confer rights on any Person other than the respective parties to this Agreement. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 11.1 shall be deemed effective service of process on such party.

(b) To the extent that any party has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, each of such Seller or Purchaser hereby irrevocably waives such immunity in respect of its obligations with respect to this Agreement.

(c) Each party irrevocably consents to service of process in the manner provided for the giving of notices pursuant to Section 11.1 of this Agreement. Nothing in this Section 11.3 shall affect the right of any party to serve process in any other manner permitted by Law.

Section 11.4 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures were upon the same instrument, and shall become effective when one or more counterparts have been signed by each of the parties and delivered (by telecopy, electronic delivery or otherwise) to the other parties. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signatures.

Section 11.5 Entire Agreement. This Agreement, together with the Related Agreements, the Disclosure Letters, the Non-Disclosure Agreement and the letter agreements set forth in Section 11.5 of the Seller Disclosure Letter and all annexes and exhibits hereto and thereto, embody the entire agreement of the parties hereto with respect to the subject matter hereof and supersede all prior agreements with respect thereto.

Section 11.6 Amendment, Modification and Waiver. No amendment to this Agreement shall be effective unless it shall be in writing and signed by each Party hereto. Any failure of a party to comply with any obligation, covenant, agreement or condition contained in this Agreement may be waived by the party entitled to the benefits thereof only by a written instrument duly executed and delivered by the party granting such waiver, but such waiver or failure to insist upon strict compliance with such obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure of compliance.

Section 11.7 Severability. If any provision of this Agreement or the application of any such provision is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement or invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable Law, the parties waive any provision of law that renders any provision of this Agreement invalid, illegal or unenforceable in any respect. The parties shall, to the extent lawful and practicable, use their reasonable efforts to enter into arrangements to reinstate the intended benefits, net of the intended burdens, of any such provision held invalid, illegal or unenforceable.

Section 11.8 Successors and Assigns; No Third-Party Beneficiaries. This Agreement and all its provisions shall be binding upon and inure to the benefit of the parties and their respective permitted successors and assigns. Nothing in this Agreement, whether expressed or implied, will confer on any Person, other than the parties hereto or their respective permitted successors and assigns, any rights, remedies or Liabilities; provided that the provisions of Article X will inure to the benefit of the Indemnified Parties. No party may assign its rights or obligations under this Agreement without the prior written consent of the other parties hereto and any purported assignment without such consent shall be void; provided, that Purchaser may, without the consent of Sellers, assign any or all of its rights or obligations hereunder to any of its Subsidiary that is wholly owned (although no such assignment shall relieve Purchaser of its obligations to Sellers or any Purchaser Indemnified Party hereunder) and Parent and Sellers may, without the consent of Purchaser, assign their right to receive the Closing Purchase Price and the Earn-Out Issuances to any their respective Affiliates.

Section 11.9 Publicity. With respect to any information in respect of the transactions contemplated hereby which shall not have been previously issued or disclosed, except as required by Law (including the rules and regulations of any applicable stock exchange), each of Parent and Purchaser agrees that neither it nor any of its Affiliates will issue a press release or make any other public statement or release any public communication with respect thereto without the prior consultation with the other Party. Purchaser and Parent agree, to the extent possible and legally permissible, to notify, cooperate and consult with, the other party prior to issuing or making any such public statement (and be provided a reasonable opportunity to comment on such public statement).

Section 11.10 WAIVER OF JURY TRIAL. TO THE FULLEST EXTENT PERMITTED BY LAW, EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING OR COUNTERCLAIM ARISING OUT OF, IN WHOLE OR IN PART, OR RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR THE RELATED AGREEMENTS.

Section 11.11 Expenses. Except as otherwise expressly stated in this Agreement, Sellers shall bear the costs of Seller Transaction Expenses, Purchaser shall bear the costs of Purchaser Transaction Expenses, and any other costs, expenses, or charges incurred by any of the parties hereto shall be borne by the party incurring such cost, expense or charge, in each case, whether or not the transactions contemplated hereby shall be consummated; provided, however, that Purchaser and Parent shall share in equal proportions any HSR Act filing fees.

Section 11.12 Specific Performance and Other Equitable Relief. The parties hereby expressly recognize and acknowledge that immediate, extensive and irreparable damage would result, no adequate remedy at law would exist and damages would be difficult to determine in the event that any provision of this Agreement is not performed in accordance with its specific terms or is otherwise breached. Each party further acknowledges that a breach or violation of this Agreement cannot be sufficiently remedied by money damages alone and, accordingly, each party shall be entitled, without the need to post a bond or other security, in addition to damages and any other remedies provided at law or in equity, to specific performance, injunctive and other equitable relief in order to enforce or prevent any violation. Each party agrees not to oppose the granting of such equitable relief, and to waive, and to cause its representatives to waive, any requirement for the securing or posting of any bond in connection with such remedy.
