To the knowledge of MCK, no claim has ever been made by a Taxing Authority in a jurisdiction where any MCK Contributed Entity, or, with respect to the MCK Contributed Assets and Core MTS Business, any of MCK and its Affiliates, does not file Tax Returns that it is or may be subject to taxation by that jurisdiction as a consequence of operating the Core MTS Business.

(iv) None of the MCK Contributed Entities (A) has, during the last eight years, been a member of an affiliated, consolidated, combined or unitary group (other than any such group the common parent of which was MCK) or (B) during the two-year period ending on the date hereof, was a distributing corporation or a controlled corporation in a transaction intended to be governed by Section 355 of the Code.

(v) Neither the Company, nor any of its Affiliates (with respect to the Core MTS Business) nor any MCK Contributed Entity will be required to include in or for, or allocate with respect to, a Post-Closing Tax Period a material amount of taxable income attributable to income economically realized in a Pre-Closing Tax Period (nor has any material deduction economically attributable to a Post-Closing Tax Period been claimed in a Pre-Closing Tax Period), including as a result of any (A) change in accounting method made prior to the Closing Date, (B) closing or similar agreement with any Tax authority entered into prior to the Closing, (C) installment sale or open transaction disposition made on or prior to the Closing Date, (D) election under Section 108(i) of the Code or (E) prepaid amount received prior to the Closing Date.

(vii) Reference is made to the memorandum dated May 26, 2016 from McKesson Tax to Tax Files with the subject heading “Section 197 Intangibles – Anti-Churning”

(the “ MCK Tax Memo ”). All of the factual statements set forth in the MCK Tax Memo are true, correct and complete in all material respects, including (i) that the entity referred to in the MCK Tax Memo as McKesson Financial Holdings or IP3 “is not liquidating and continues to operate with remaining IP related to businesses not [being transferred to the Company],” (ii) that the MCK IPCo Owned Intellectual Property does not include “goodwill, going concern value, trademarks or trade names [or] workforce” (iii) that the MCK IPCo Owned Intellectual Property consists only of “computer software, coding, and technology know-how” related to the use of such computer software and coding and (iv) that the MCK IPCo Owned Intellectual Property was developed in 2001 or thereafter; provided , that for the avoidance of doubt, neither the MCK Tax Memo nor this Section 4.02(s)(vii) includes, or shall be construed as including, any representation regarding any conclusion of law. Further to clause (i) of the preceding sentence, IP3 will not have disposed of 90 percent or more of the fair market value of its net assets or 70 percent or more of the fair market value of its gross assets held immediately prior to the transactions contemplated by the MCK Tax Memo, treating any expenses paid by IP3 and any redemptions or distributions of cash or other property by IP3 in connection with the transactions contemplated by the MCK Tax Memo as assets of IP3. Any license under which IP3 has or had the right to develop the Intellectual Property that will be MCK IPCo Owned Intellectual Property relates solely to the right to use “computer software, coding, and technology know-how” related to the use of such computer software and coding.

(viii) Notwithstanding any other provision of this Agreement, other than Section 4.02(s)(vii), nothing in this Agreement (including the other clauses of this Section 4.02(s) or otherwise) shall be construed as providing a representation or warranty with respect to the existence, amount, expiration date or limitations on (or availability of) any Tax asset or method of Tax accounting of any of the MCK Contributed Entities for a Post-Closing Tax Period.

(t) Insurance . The Core MTS Business either has insurance policies or is a named insured under insurance policies of its Affiliates, in such amounts and against such risks, as would reasonably be expected with regard to the nature and size of the Core MTS Business and as is required by Applicable Law; all such insurance policies are in full force and effect; and to the knowledge of MCK, MCK (or the applicable Affiliate) has not received notice of cancellation or termination with respect to any such insurance policies. Section 4.02(t) of the MCK Disclosure Schedule sets forth each such insurance policy applicable to the Core MTS Business.

(u) Acquisition for Investment. MCK is acquiring a beneficial ownership interest in the Units for investment for its own account and not with a view to, or for offer or sale in connection with, any distribution thereof.

(iv) the Echo Indemnified Parties may assert any claim for indemnification against the MCK Indemnifying Parties under Section 8.03(a)(v) and Section 8.03(a)(w) only until the date on which such representation and warranty ceases to survive as provided in Section 8.01; and

(v) the Damages for which the Echo Indemnified Parties are indemnified under this Section 8.03 shall not include punitive or exemplary damages (except for punitive or exemplary damages payable to third parties in respect of third-party claims).

(a) In the event that any written claim or demand for which an indemnifying party (the “ Indemnifying Party ”) may have liability to any indemnified party (the “ Indemnified Party ”) hereunder is asserted against or sought to be collected from any Indemnified Party by a third party, the Indemnified Party shall notify the Indemnifying Party of such claim promptly (by notice to the Echo Representative in the case of indemnification claimed under Section 8.02 and by notice to MCK in the case of indemnification claimed under Section 8.03). Notwithstanding the foregoing, the Indemnified Party’s failure to so notify the Indemnifying Party shall not (except as stated in Section 8.01 with respect to the survival of representations and warranties and the right to claim thereunder) preclude it from seeking indemnification hereunder except to the extent such failure materially prejudices the Indemnifying Party’s ability to defend as provided herein (in which event the Indemnified Party’s right to indemnity will be reduced equitably to reflect such material prejudice). The Indemnifying Party shall promptly following notice of the claim from the Indemnified Party (but in any case no less than 10 Business Days before the due date for the answer or response to a claim) notify the Indemnified Party of its desire to defend such claim. In the event the Indemnifying Party so notifies the Indemnified Party, the Indemnifying Party shall have the right to defend such claim at its own expense and by

counsel of its own choosing reasonably satisfactory to the Indemnified Party; provided that (i) the Indemnifying Party states in such notice that the Indemnifying Party will, and thereby covenants to, indemnify, defend and hold harmless the Indemnified Party from and against the entirety of any and all Damages the Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of, or caused by such claim, (ii) such claim involves only money damages and does not seek an injunction or other equitable relief against the Indemnified Party, (iii) the Indemnified Party has not been advised by counsel that an actual or potential conflict exists between the Indemnified Party and the Indemnifying Party in connection with the defense of such claim, (iv) such claim does not relate to or otherwise arise in connection with any criminal or regulatory enforcement action, and (v) such claim is not in respect of Taxes of the Indemnified Party. If the Indemnifying Party elects to, and is able to, defend such claim, the Indemnified Party may participate at its own expense in the defense of such claim by counsel of its own choosing. Notwithstanding the foregoing, the Indemnified Party shall be entitled to direct or control the defense of such claim if (x) the Indemnified Party waives all right to indemnification it may have in respect of such claim under this Article 8 or (y) the Indemnifying Party elects not to defend against such claim or fails to vigorously defend such claim thereafter. Unless the Indemnified Party has assumed the defense of a claim, the Indemnifying Party shall have the authority on behalf of the Indemnified Party to settle any such claim (with the Indemnifying Party being responsible for all costs and expenses of such settlement); provided that the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed) shall be required unless (1) such settlement releases the Indemnified Party from all liabilities and obligations with respect to such claim, (2) such settlement shall not permit any order, injunction or other equitable relief to be entered, directly or indirectly, against the Indemnified Party, and (3) there is no admission by the Indemnified Party of any liability or of any violation of Applicable Law. Each of the Indemnifying Party and the Indemnified Party shall cooperate, and cause its Affiliates to cooperate, in the defense of any claim. No settlement of any claim may be made by the Indemnified Party without the consent of the Indemnifying Party (such consent not to be unreasonably withheld, delayed or conditioned).

Section 8.05 . Calculation of Damages. The amount of any Damages payable under this Article 8 by the Indemnifying Party shall be net of any (i) amounts actually recovered by the Indemnified Party under applicable insurance policies or from any other Person alleged to be responsible therefor (net of any Tax and expenses, including the amount of any increases in insurance premiums (but only to the extent such increases actually and directly result from the applicable claim and are payable in respect of the two year period commencing on the date such claim is made), incurred by the Indemnified Party in connection with such recovery), and (ii) Tax benefit actually realized by the Indemnified Party arising from the incurrence or payment of any such Damages at any time prior to MCK’s direct or indirect disposition of its interest in the Company. If the Indemnified Party receives any amounts under applicable insurance policies, or from any other Person alleged to be responsible for any Damages, subsequent to an indemnification payment by the Indemnifying Party or equity adjustment pursuant to Section 8.06(a), then such Indemnified Party’s relative Membership Percentage in the Company shall be adjusted, or such Indemnified Party shall promptly reimburse the Indemnifying Party for any payment made or expense incurred by such Indemnifying Party in connection with providing such indemnification payment, up to the equity adjustment or payment amount received by the Indemnified Party, net of any Tax and expenses, including the amount of any increases in

insurance premiums (but only to the extent such increases actually and directly result from the applicable claim and are payable in respect of the two year period commencing on the date the applicable claim is made), incurred by such Indemnified Party in collecting such amount. The Indemnified Party shall use commercially reasonable efforts to pursue any claim against any insurer under its insurance policies (or insurance policies under which it is a named insured) or any other Person alleged to be responsible for any Damages (other than the Indemnifying Party) for Damages for which it seeks indemnification hereunder and, subject to the foregoing sentence, the expenses reasonably incurred by the Indemnified Party in pursuing any such claim shall be Damages subject to indemnification hereunder; provided that nothing in this Section 8.05 shall be deemed to obligate an Indemnified Party to maintain any insurance policy or to file a lawsuit or commence any other proceeding against any insurer or any other Person.

(a) Subject to Section 8.02(a)(vi) and MCK’s Top-up Option (as defined in the LLC Agreement) and the last sentence of this Section 8.06(a), the exclusive remedy for any Damages for which the MCK Indemnified Parties are indemnified under Section 8.02 (other than with respect to claims brought under Section 8.02(a)(x), which may be paid solely in cash), on the one hand, or for which the Echo Indemnified Parties are indemnified under Section 8.03 (other than with respect to claims brought under Section 8.03(a)(y) and Section 8.03(a)(x) which may be paid solely in cash), on the other hand, shall be at the sole election of the Indemnifying Party, in the form of either (X) an adjustment by the Company to the Membership Percentage of Echo or the MCK Contributors and MCK IPCo, as applicable, or (Y) payment in cash by the Indemnifying Party. The number of Units to be so adjusted (the “ Adjustment Units ”) shall be determined (1) in the case of Damages representing expenses incurred directly by the Indemnified Party, by dividing (i) the amount of the indemnifiable Damages by (ii) the Membership Unit Value, and (2) otherwise , by dividing (i) the amount of the indemnifiable Damages by (ii) the product of (A) the Membership Unit Value and (B) the aggregate Membership Percentages of the Indemnified Party as of the time such Damages arose. The applicable Indemnifying Party shall have a number of Units equal to the Adjustment Units cancelled for no consideration. The number of Adjustment Units deducted from each MCK Contributor and MCK IPCo shall be allocated among the MCK Contributors and MCK IPCo (i) based on which such Person contributed, sold or assigned the asset or liability to which such Damages relate, if ascertainable, and (ii) otherwise shall be allocated among the MCK Contributors and MCK IPCo based on their relative Membership Percentage as of the time the related Damages arose. With respect to Damages representing expenses incurred directly by the Indemnified Party, such Indemnified Party shall also be entitled to payment of and/or reimbursement by the Company of such expenses at the time such expenses are payable by such Indemnified Party.

(b) Except in the case of fraud, after the Closing, (x) the rights and remedies of the Parties hereto (i) under this Article 8, (ii) under Section 2.02(f) and (iii) to seek specific performance or injunctive relief, shall be sole and exclusive and in lieu of any and all other rights and remedies which the parties may have under this Agreement or otherwise against each other with respect to (A) any breach or inaccuracy of any representation or warranty set forth in this Agreement or any certificates delivered hereunder or (B) any failure to perform any covenant or

agreement set forth in this Agreement, and (y) each party expressly waives any and all other rights or causes of action it or its Affiliates may have against any other party or its Affiliates now or in the future with respect to the representations, warranties, covenants and agreements set forth in this Agreement and the certificates delivered hereunder.

(c) The rights of each Echo Indemnified Party and each MCK Indemnified Party under this Article 8 are cumulative, and each Echo Indemnified Party and MCK Indemnified Party will have the right in any particular circumstance, in its sole discretion, to enforce any provision of this Article 8 without regard to the availability of a remedy under any other provision of this Article 8 provided that no Party shall be permitted to recover more than once for each loss.

(d) The Parties hereby acknowledge and agree that, notwithstanding the foregoing provisions of this Article 8, an Indemnified Party may have certain rights to indemnification, advancement of expenses and/or insurance provided by other sources. The Parties hereby acknowledge and agree (i) that the Indemnifying Party is the indemnitor of first resort (i.e., its obligations to an Indemnifying Party are primary and any obligation of such other sources to advance expenses or to provide indemnification for the same expenses or liabilities incurred by such Indemnifying Party are secondary) and (ii) that the Indemnifying Party shall be required to advance the full amount of expenses incurred by an Indemnifying Party and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement without regard to any rights an Indemnified Party may have against such other sources. The Parties further agree that no advancement or payment by such other sources on behalf of an Indemnified Party with respect to any claim for which such Indemnified Party has sought indemnification, advancement of expenses or insurance from an Indemnifying Party shall affect the foregoing, and that such other sources shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of such Indemnified Party against the Indemnifying Party.

(ii) by either Echo Holdco or MCK if the Transactions have not occurred on or prior to June 28, 2017 (the “ End Date ”); provided that the right to terminate this Agreement shall not be available to any party whose failure to fulfill any obligation under this Agreement shall have been the cause, or shall have resulted in, the failure of the Closing prior to the End Date;

(iii) by either Echo Holdco or MCK if there shall be any Order preventing the consummation of the Transactions in effect that shall have become final and nonappealable;

(iv) by MCK if there shall have occurred, after the date hereof, (A) any change in Applicable Law or (B) any Tainting Acquisition that was not within the control of, or at the request of MCK, in each case, as a result of which MCK’s Tax Opinion Advisor shall have notified MCK that such Tax Opinion Advisor will be unable to render a Section 355(e) Opinion; provided, however , that following any such notification by MCK’s Tax Opinion Advisor, MCK shall use its reasonable best efforts to obtain a Section 355(e) Opinion from an Alternative Tax Opinion Advisor within 60 days of such notification, and if MCK obtains a Section 355(e) Opinion from an Alternative Tax Opinion Advisor within such period (or fails to obtain a Section 355(e) Opinion from an Alternative Tax Opinion Advisor within such period by reason of failure to use its reasonable best efforts to do so), MCK may not terminate this Agreement pursuant to this Section 9.01(a)(iv). For purposes of determining whether it is unable to render a Section 355(e) Opinion by reason of a Tainting Acquisition or a change in Applicable Law, MCK’s Tax Opinion Advisor shall be required to assume the Assumed Facts, provided that prior to MCK being permitted to terminate this Agreement pursuant to this Section 9.01(a)(iv), MCK shall use commercially reasonable efforts, and shall permit and provide such information so as to permit the Echo Parties to use commercially reasonable efforts, to receive written confirmation from the holder of the stock acquired in such Tainting Acquisition to the effect that (x) such holder will not exchange such stock for SpinCo (as defined in the LLC Agreement) common stock and (y) such holder is not a shareholder of Echo Holdco or a Person whose stock would be aggregated with, or attributed to, any such Person under Section 355(e)(4)(C) of the Code.

(v) by Echo or MCK if there shall have occurred, after the date hereof, (i) a change in Applicable Law (for this purpose, the finalization of proposed Treasury Regulation Sections 1.385-1 through 1.385-4 (or any portion thereof) in the form as of the date of this Agreement shall not be a change in Applicable Law), or (ii) a change in applicable facts since the date of this Agreement (which, for the avoidance of doubt, shall not include a change in a Party’s or Tax Opinion Advisor’s knowledge of underlying facts that have not changed since the date of this Agreement) not within the control of Echo, in each case as a result of which change in Applicable Law or facts Echo’s Tax Opinion Advisor shall have notified Echo that such Tax Opinion Advisor will be unable to render an Echo 721 Tax Opinion; provided, however , that following any such notification by Echo’s Tax Opinion Advisor, Echo shall use its reasonable best efforts to obtain an Echo 721 Tax Opinion from an Alternative Tax Opinion Advisor within 60 days of such notification, and if Echo obtains an Echo 721 Tax Opinion from an Alternative Tax Opinion Advisor within such period (or if Echo fails to obtain an Echo 721 Tax Opinion from an Alternative Tax Opinion Advisor within such period by reason of failure to use its reasonable best efforts to do so), Echo may not terminate this Agreement under this Section 9.01(a)(v);

(a) The Company shall give each of the Initial Members (and their Permitted Transferees) written notice (an “ Issuance Notice ”) of any proposed issuance by the Company of any Equity Securities at least twenty (20) Business Days prior to the proposed issuance date. The Issuance Notice shall specify the price at which such Equity Securities are to be issued and the other material terms of the issuance (including the terms of the Equity Securities proposed to be issued).

(b) If any Initial Member (or its Permitted Transferees) desires to purchase or to have any of its Affiliates purchase any or all of its Membership Percentage of the Equity Securities specified in the Issuance Notice, it shall deliver a written notice to the Company (each a “ Preemptive Rights Exercise Notice ”) of its election to purchase such Equity Securities within ten (10) Business Days of receipt of the Issuance Notice. The Preemptive Rights Exercise Notice shall specify the number (or amount) of Equity Securities to be purchased by such party or its Affiliates and shall constitute exercise by such party of its rights under this Section 3.07 and a binding agreement of such party or such party’s applicable Affiliates to purchase, at the price and on the terms specified in the Issuance Notice and in accordance with the terms of this Section 3.07, the number of shares (or amount) of Equity Securities specified in the Preemptive Rights Exercise Notice with such purchase to be consummated as promptly as reasonably practicable. If, at the termination of such ten (10) Business-Day period, any Initial Member (or its Permitted Transferees) shall not have delivered a Preemptive Rights Exercise Notice to the Company, such party shall be deemed to have waived all of its rights under this Section 3.07 with respect to the purchase of such Equity Securities. Promptly following the termination of such ten (10) Business Day period, the Company shall deliver to each of the Initial Members (or its Permitted Transferees) a copy of any Preemptive Rights Exercise Notice it has received or notify each of the Initial Members that no Preemptive Rights Exercise Notices have been received (each a “ Second Notice ”).

If any such Initial Member (or its Permitted Transferees) desires to purchase or to have any of its Affiliates purchase such remaining portion, it shall deliver a written notice to the Company of its election to purchase such remaining portion within five (5) Business Days following receipt of the Second Notice from the Company.

(d) The Company shall have ninety (90) days from the date of the Issuance Notice to consummate the proposed issuance of any or all of such Equity Securities that the Initial Members (or its Permitted Transferees) have not elected to purchase at a price equal to or greater than the price specified in the Issuance Notice and otherwise upon terms that are not less favorable to the Company than those specified in the Issuance Notice; provided , that if any Governmental Approvals are required in connection with such issuance, such 90-day period shall be extended until the expiration of five (5) Business Days following the date on which all Governmental Approvals are obtained and any applicable waiting periods under applicable Law have expired or been terminated, but in no event will such period be extended for more than an additional 180 days. If the Company proposes to issue any such Equity Securities after such 90-day (or longer, as permitted by the preceding sentence) period, it shall again comply with the procedures set forth in this Section 3.07.

(e) At the consummation of the issuance of such Equity Securities the Company shall issue certificates or other appropriate instruments representing the Equity Securities to be purchased by each party exercising preemptive rights pursuant to this Section 3.07 registered in the name of such party, against payment by such party of the purchase price for such Equity Securities in accordance with the terms and conditions as specified in the Issuance Notice.

(f) Notwithstanding the foregoing, no Initial Member (or its Permitted Transferees) shall be entitled to purchase Equity Securities as contemplated by this Section 3.07 in connection with issuances of Equity Securities (i) to employees of the Company or any of its Subsidiaries pursuant to employee benefit plans or arrangements approved by the Board in accordance with the terms of this Agreement (including Section 5.05(a)) (and upon the exercise of employee equity options granted pursuant to any such plans or arrangements), (ii) in connection with a Qualified IPO in accordance with the terms of this Agreement, (iii) pursuant to conversion of any convertible Equity Securities issued in compliance with the terms of this Agreement, (iv) pursuant to any exercise of the Top-up Option under Section 10.06 below, or (v) pursuant to equity adjustments as required under Section 2.03 and Section 8.06 of the Contribution Agreement or (vi) pursuant to Section 8.02(a)(ix). The Company shall not be obligated to consummate any

proposed issuance of Equity Securities, nor be liable to any Initial Member (or its Permitted Transferees) if the Company has not consummated any proposed issuance of Equity Securities, pursuant to this Section 3.07 for whatever reason, regardless of whether it shall have delivered an Issuance Notice or received any Preemptive Rights Exercise Notices in respect of such proposed issuance.

Notwithstanding Sections 4.04 and 4.07 above, on any matter requiring an approval or consent of Members under this Agreement or the Act at a meeting of Members, the Members may take such action without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, shall be signed by all of the Members entitled to vote thereon.

Section 4.09. Record Date. For the purpose of determining Members entitled to notice of or to vote at any meeting of Members, or entitled to receive a payment of any kind, or in order to make a determination of Members for any other proper purpose, the Board may fix in advance a date as the record date for any such determination of Members, such date in any case to be not more than thirty (30) days prior to the date on which the particular meeting or action, requiring such determination of such Members, is to be held or taken.

When a determination of Members entitled to vote at any meeting of Members has been made as provided in this Section 4.09 such determination shall apply to any adjournment thereof unless the Board fixes a new record date, which it shall do if the meeting is adjourned to a date more than 90 days after the date fixed for the original meeting.

(c) The secretary of the Company (the “ Secretary ”) shall circulate to each Director an agenda for each meeting of the Board not less than four days in advance of such meeting, or no less than two days in advance of any special meeting, if the Chairman has exercised his or her right pursuant to Section 5.03(b) to reduce the notice required for such meeting to no less than two days. Such agenda shall include any matters that any Director may reasonably request be included on such agenda.

If a quorum is not present at the Adjourned Meeting and the sole reason for such lack of quorum was the absence of the Nominee Directors of the same party whose Nominee Directors’ absence was the sole cause of the Original Meeting being adjourned, then the Directors present at such Adjourned Meeting shall constitute a valid quorum.

(e) Directors may participate in any meeting of the Board or any committee thereof by means of a conference telephone or similar communications equipment by means of which all Directors participating in such meeting may hear one another.

Notwithstanding the foregoing provisions of this Section 6.01, the Company shall indemnify a Covered Person in connection with a proceeding (or part thereof) initiated by such Covered Person only if such proceeding (or part thereof) was authorized by the Board; provided , however , that a Covered Person shall be entitled to reimbursement of his or her reasonable counsel fees with respect to a proceeding (or part thereof) initiated by such Covered Person to enforce his or her right to indemnity or advancement of expenses under the provisions of this Section 6.01 to the extent that the Covered Person is successful on the merits in such proceeding (or part thereof).

(f) Notwithstanding any provision of this Agreement to the contrary, the provisions of this Section 6.01 shall survive the termination, voluntary or involuntary, of the status of a Member as such, the termination, voluntary or involuntary, of the status of any Covered Person or other Person as to whom the provisions of this Section 6.01 apply as such and the termination of this Agreement or dissolution of the Company.

(g) The provisions of this Section 6.01 shall be applicable to any action, suit or proceeding commenced after the date of this Agreement against any Covered Person arising from any act or omission of such Covered Person acting in its capacity as such, whether occurring before or after the date of this Agreement. No amendment to or repeal of this Section 6.01, or, to the fullest extent permitted by Law, any amendment of Law, shall have any effect on the rights provided under this Section 6.01 with respect to any act or omission occurring prior to such amendment or repeal.

(h) The indemnification hereby provided and provided hereafter pursuant to the power hereby conferred by this Section 6.01 on the Board shall not be exclusive of any other rights to which any Person may be entitled, including any right under policies of insurance that may be purchased and maintained by the Company or others, with respect to claims, issues or matters in relation to which the Company would not have the power to indemnify such Person under the provisions of this Section 6.01. Such rights shall not prevent or restrict the power of the Company to make or provide for any further indemnity, or provisions for determining entitlement to indemnity, pursuant to one or more indemnification agreements or other arrangements (including creation of trust funds or security interests funded by letters of credit or other means) approved by the Board (whether or not any of the Members, Directors or Company officers shall be a party to or beneficiary of any such agreements or arrangements); provided, however , that any provision of such agreements or other arrangements shall not be effective if and to the extent that it is determined to be contrary to this Section 6.01 or applicable Law.

(i) Nothing contained in this Section 6.01 is intended to relieve any Member or any other Person from any liability or other obligation of such Person relating to the Contribution Agreement or any other Transaction Document or any other agreement or to in any way impair the enforceability of any provision of such agreements against any party thereto. No Covered Person shall be indemnified, held harmless or have any right to advancement of expenses hereunder in any claim, action, suit or proceeding relating to the Contribution Agreement or any other Transaction Document.

(j) Any indemnity under this Section 6.01 shall be provided solely out of, and only to the extent of, the Company’s assets, and no Member or Affiliate of any Member shall be required directly to indemnify any Covered Person pursuant to this Section 6.01. None of the provisions of this Section 6.01 shall be deemed to create any rights in favor of any Person other than Covered Persons and any other Person to whom the provisions of this Section 6.01 expressly apply.

(k) The Company hereby acknowledges that a Covered Person may have certain rights to indemnification, advancement of expenses and/or insurance provided by other sources. The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to a Covered Person are primary and any obligation of such other sources to advance expenses or to provide indemnification for the same expenses or liabilities incurred by such Covered Person are secondary) and (ii) that it shall be required to advance the full amount of expenses incurred by a Covered Person and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement without regard to any rights a Covered Person may have against the such other sources. The Company further agrees that no advancement or payment by such other sources on behalf of a Covered Person with respect to any claim for which such Covered Person has sought indemnification from the Company shall affect the foregoing, and such other sources shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of such Covered Person against the Company.

It is understood and agreed by the Members that each Person referred to in this Section 6.02(a) shall be permitted to undertake any and all actions of the type referred to in this Section 6.02(a) without limitation (in each case acting on behalf of the applicable Member or Affiliate of a Member in connection with such Member’s or such Member’s Affiliate’s own business and operations) and that the taking of any such actions shall not violate any legal obligation or duty (including any fiduciary duty) to any Member or other Person under or in connection with this Agreement or the Company.

(b) Notwithstanding any duty otherwise existing at Law or in equity, to the fullest extent permitted by Law, if a Member, any Director designated by a Member, any Affiliate of such Member or any officer of the Company who is also an employee of such Member (or any of such Member’s Affiliates) acquires knowledge of a potential transaction or matter which may be a business opportunity for both such Member or an Affiliate of such Member, on the one hand, and the Company or another Member or another Member’s Affiliate, on the other hand, no such Member, Director, Affiliate or officer shall have a duty to communicate or offer such business opportunity to the Company or such other Member or such other Member’s Affiliate, and no such Person shall be liable to the Company, the other Members and their Affiliates in respect of any such matter (including for any breach of fiduciary or other duties) by reason of the fact that such Member or any Affiliate of such Member pursues or acquires such business opportunity for itself or by reason of the fact that such Member, Director, Affiliate or officer directs such opportunity to such Member or an Affiliate of such Member or does not communicate information regarding such opportunity to the Company. Notwithstanding the foregoing, the first sentence of this Section 6.02(b) shall not apply to any such knowledge or business opportunity acquired by any Director who is an officer or other employee of the Company in his or her capacity as an officer or other employee of the Company. For the avoidance of doubt, a Director shall not be considered to be an officer of the Company merely by virtue of holding such position, the position of Chairman of the Board, Executive Vice Chairman of the Board or any other Board-level position.

The Board shall initially designate an MCK Member as the Tax Matters Member. The Tax Matters Member shall take such action as may be necessary to cause, to the extent possible, each other Member to become a notice partner within the meaning of Code Section 6231(a)(8).

(h) The Company shall, if it is so eligible, make an election out of the Partnership Tax Audit Rules under Section 6221(b) (as in effect after December 31, 2017), and the Members shall provide the Company with such information as is reasonably necessary to make such election. The Company shall not make an election under Section 6231(a)(1)(B)(ii) of the Code (as in effect prior to December 31, 2017). In the event the Company has made an election out of the Partnership Tax Audit Rules under Section 6221(b) (as in effect after December 31, 2017), or is excluded from the definition of “partnership” under Section 6231(a)(1) (as in effect prior to January 1, 2018), and a Member becomes subject to an audit, examination, or other proceeding such Member shall notify the other Members of such audit, examination or other proceeding insofar as it relates to or involves the Company and shall provide information to the other Members upon reasonable request in respect of significant matters that relate to or involve the Company.

Except as set forth in Section 8.01(b), Profit and Loss of the Company for each Tax Year of the Company shall be allocated among the Capital Accounts of the Members pro rata in accordance with the Members’ respective Membership Percentages, unless otherwise required by Section 704(b) of the Code and the Treasury Regulations thereunder; provided , that if the Membership Percentages of the Members are adjusted pursuant to Section 2.03 or Section 8.06 of the Contribution Agreement, Profit and Loss of the Company shall be allocated so as to give effect to the adjusted Membership Percentages, such that the Capital Accounts of the Members equal the Capital Accounts that the Members would have had if all allocations under this Section 8.01(a) for prior Tax Years had been pro rata in accordance with the adjusted Membership Percentages.

(i) Each item of Depreciation in respect of the MCK IPCo Owned Intellectual Property (as defined in the Contribution Agreement) for any Tax Year shall be specially allocated to MCK IPCo and/or any successor(s) in interest to MCK IPCo’s Initial Units (in proportion to the number of such Units then held by MCK IPCo and/or any such successor(s) in interest); provided , however , that no such allocation shall be made to the extent such allocation would result in aggregate Capital Account balances for the MCK Members that constitute less than 50.1% of the aggregate Capital Account balances of all Members, after giving effect to all allocations made for such Tax Year pursuant to this Section 8.01.

(ii) All Unrealized Gain and Realized Gain for any Tax Year shall be allocated entirely to MCK IPCo and/or any successor(s) in interest to MCK IPCo’s Initial Units (in proportion to the number of such Units then held by MCK

IPCo and/or any such successor(s) in interest) to the extent of the excess, if any, of (A) the cumulative amount of Depreciation allocated to all such Persons pursuant to Section 8.01(b)(i) for all prior Tax Years, over (B) the cumulative amount of Unrealized Gain and Realized Gain allocated to such Persons pursuant to this Section 8.01(b)(ii) for all prior Tax Years.

(iii) No allocation of Loss shall be made to any Member if, as a result of such allocation, such Member would have a negative balance in its Adjusted Capital Account, unless at the time of such allocation, all Adjusted Capital Accounts are equal to zero.

(iv) Member Nonrecourse Debt Minimum Gain Chargeback . Losses attributable to partner nonrecourse debt (as defined in Treasury Regulation Section 1.704-2(b)(4)) shall be allocated in the manner required by Treasury Regulation Section 1.704-2(i). If there is a net decrease during a Tax Year in Member Nonrecourse Debt Minimum Gain, Profits for such Tax Year (and, if necessary, for subsequent Tax Years) shall be allocated to the Members in the amounts and of such character as determined according to Treasury Regulation Section 1.704-2(i)(4). This Section 8.01(b)(iv) is intended to be a minimum gain chargeback provision that complies with the requirements of Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted in a manner consistent therewith.

(v) Minimum Gain Chargeback . Nonrecourse deductions (as determined according to Treasury Regulation Section 1.704-2(b)(1)) for any Tax Year shall be allocated to each Member ratably among such Members based upon the manner in which Profits (determined without regard to such non-recourse deductions) are allocated among the Members for such Tax Year. Except as otherwise provided in Section 8.01(b)(iv), if there is a net decrease in the Minimum Gain during any Taxable Year, each Member shall be allocated Profits for such Tax Year (and, if necessary, for subsequent Tax Years) in the amounts and of such character as determined according to Treasury Regulation Section 1.704-2(f). This Section 8.01(b)(v) is intended to be a Minimum Gain chargeback provision that complies with the requirements of Treasury Regulation Section 1.704-2(f), and shall be interpreted in a manner consistent therewith.

(vi) Qualified Income Offset . If any Member that unexpectedly receives an adjustment, allocation or distribution described in Treasury Regulation Section 1.704-1(b)(2)(ii)(d)(4), (5) and (6) has an Adjusted Capital Account Deficit as of the end of any Tax Year, computed after the application of Section 8.01 but before the application of this Section 8.01(b)(vi), then items of Company income and gain for such Tax Year shall be allocated to such Member in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations, the Adjusted Capital Account Deficit of the Member as soon as possible (and, if two or more Members have such deficits, in proportion to their deficits). This Section 8.01(b)(vi) is intended to be a qualified income offset provision as described in Treasury Regulation Section 1.704-l(b)(2)(ii)(d) and shall be interpreted in a manner consistent therewith.

(vii) Allocation of Certain Profits and Losses . To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to Section 734(b) of the Code or Section 743(b) of the Code is required pursuant to Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(4) to be taken into account in determining Capital Accounts, the amount of such adjustment to Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be specially allocated to the Members in accordance with their interests in the event Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(2) applies, or to the Member to whom such distribution was made in the event Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.

(viii) The allocations set forth in (iii)-(vi) of this Section 8.01(b) (the “ Regulatory Allocations ”) are intended to comply with certain requirements of Sections 1.704-l(b) and 1.704-2 of the Treasury Regulations. The Regulatory Allocations may not be consistent with the manner in which the Members intend to allocate Profit and Loss of the Company or make the Company’s distributions. Accordingly, notwithstanding the other provisions of this Section 8.01, but subject to the Regulatory Allocations, income, gain, deduction, and loss shall be reallocated among the Members so as to eliminate the effect of the Regulatory Allocations and thereby cause the respective Capital Accounts of the Members to be in the amounts (or as close thereto as possible) they would have been if Profit and Loss (and such other items of income, gain, deduction and loss) had been allocated without reference to the Regulatory Allocations. In general, the Members anticipate that this will be accomplished by specially allocating other Profit and Loss (and such other items of income, gain, deduction and loss) among the Members so that the net amount of the Regulatory Allocations and such special allocations to each such Member is zero.

(i) Allocations Generally . The income, gains, losses and deductions of the Company will be allocated for federal, state and local income tax purposes among the Members in accordance with the allocation of such income, gains, losses, and deductions among the Members for computing their Capital Accounts pursuant to Section 8.01(a) and Section 8.01(b); except that if any such allocation is not permitted by the Code or other applicable Law, the Company’s income, gains, losses and deductions will be allocated among the Members so as to reflect as nearly as possible the allocation set forth herein in computing their Capital Accounts.

(ii) Code Section 704(c) Allocations . Items of the Company’s taxable income, gain, loss and deduction with respect to any property contributed to the capital of the Company shall be allocated among the Members in accordance with

Section 704(c) of the Code so as to take account of any variation between the adjusted basis of such property to the Company for federal income tax purposes and its Gross Asset Value. In addition, if the Gross Asset Value of any asset of the Company is adjusted pursuant to the requirements of Treasury Regulation Section 1.704-1(b)(2)(iv)(e) or (f), then subsequent allocations of items of taxable income, gain, loss and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Gross Asset Value in the same manner as under Section 704(c) of the Code. The Board shall determine all allocations pursuant to this Section 8.01(c)(ii) using the “traditional method” under Treasury Regulation Section 1.704-3(b).

(iii) Allocation of Tax Credits, Tax Credit Recapture, Etc . Tax credits, tax credit recapture, and any items related thereto shall be allocated to the Members according to their interests in such items as determined by the Board, taking into account the principles of Treasury Regulation Section 1.704-1(b)(4)(ii).

(iv) Effect of Allocations . Allocations pursuant to this Section 8.01(c) are solely for purposes of federal, state and local taxes and shall not affect, or in any way be taken into account in computing, any Member’s Capital Account or share of Profit, Loss, other items or distributions pursuant to any provision of this Agreement.

(i) To the fullest extent permitted by Law, the Company shall distribute to the Members with respect to each Estimated Tax Distribution Period of each Tax Year, no later than five (5) days prior to the Estimated Tax Distribution Date that corresponds to such Estimated Tax Distribution Period, an amount of cash equal to the Estimated Tax Distribution Amount with respect to such Estimated Tax Distribution Period; provided that if a Member’s Annual Tax Distribution Amount for a Tax Year exceeds the total of the Estimated Tax Distribution Amounts for such Member with respect to all Estimated Tax Distribution Periods of such Tax Year, the Company shall, within 20 days after providing Schedules K-1 to the Members pursuant to Section 7.04(b)(ii) (and in no event later than five (5) days prior to the unextended due date for any Member’s U.S. federal income tax return), distribute to such Member an amount of cash equal to such excess.

(ii) If a Member has a Tax Distribution Deficit in respect of any Estimated Tax Distribution Period or any Tax Year, then promptly upon receipt by the Company from such Member of such documentation or other information as the Board determines in its reasonable discretion is sufficient to demonstrate the existence and amount of such Tax Distribution Deficit, the Company shall distribute to such Member an amount of cash such that, after giving effect to such distribution, such Member’s Tax Distribution Deficit is reduced to zero.

(iii) No later than ten (10) Business Days following an Adjustment Event, the Company shall distribute to each Member such Member’s Adjustment Tax Distribution Amount in respect of such Adjustment Event; provided , that if such Adjustment Event occurs after a Qualified MCK Exit, the amount distributed to each of Echo, on the one hand, and to the MCK Members and their Permitted Transferees as a group, on the other hand, pursuant to this Section 8.02(a)(iii) shall be at least equal to Echo’s, or the MCK Members’ and their Permitted Transferees’, on the other hand, Correlative Adjustment Amount for such Adjustment Event.

(iv) No later than ten (10) Business Days following each of (A) the date on which the Company files its original IRS Form 1065 for any Tax Year and (B) the extended due date for Echo’s U.S. federal income tax return for such Tax Year, the Company shall make a distribution to the Members, pro rata to the Members’ respective Pro Rata Tax Distribution Amounts. Such distribution shall not exceed the lesser of (x) the amount of cash available for distribution by the Company (as determined by the Board in its reasonable discretion and, for the avoidance of doubt, taking into account reasonably foreseeable obligations of the Company under Section 8.02(a)(i)) (“ Available Cash ”) and (y) the amount needed to distribute to each Member such Member’s Pro Rata Tax Distribution Amount.

(v) Immediately following any distribution under Section 8.02(a)(iii), the Company shall make a distribution to the Members, pro rata to the Members’ respective Adjustment Pro Rata Tax Distribution Amounts in respect of the Adjustment Event to which the distribution under Section 8.02(a)(iii) related. Such distribution shall not exceed the lesser of (x) the amount of Available Cash and (y) the amount needed to distribute to each Member such Member’s Adjustment Pro Rata Tax Distribution Amount.

(vi) If the Company does not have sufficient Available Cash (as determined by the Board in its reasonable discretion) to make the distributions described in Section 8.02(a)(i), Section 8.02(a)(ii) or Section 8.02(a)(iii) to all Members entitled to distributions thereunder, such distributions shall be made first to Echo until Echo has received the full amount of distributions to which it is entitled thereunder, and then to all other Members pro rata to the amounts of distributions to which they are entitled thereunder.

(vii) If the Company fails to distribute an amount to which a Member is entitled under this Section 8.02(a) due to the Available Cash limitations in Section 8.02(a)(iv), Section 8.02(a)(v) or Section 8.02(a)(vi), the amount not so distributed shall be added to the Tax Distribution Arrearage for such Member, without duplication of amounts previously added to the Tax Distribution Arrearage for such Member.

(viii) A Member’s Tax Distribution Arrearage shall be compounded semiannually at the Tax Distribution Arrearage Return Rate.

(ix) As and to the extent that the Company has Available Cash (as determined by the Board in its reasonable discretion), until all Members’ Tax Distribution Arrearages are reduced to zero, the Company shall distribute such amount of cash to the Members pro rata to their respective Tax Distribution Arrearages, and each Member’s Tax Distribution Arrearage shall be reduced by the amount so distributed to such Member; provided that upon the occurrence of a Conversion Event with respect to one or more Units held by a Member or one of its Permitted Transferees, unless such Person waives the application of this proviso in respect of such Conversion Event by delivering notice of such waiver to the Company in writing prior to the occurrence of such Conversion Event, (x) the Company shall issue to such Person a number of new Units equal to the Conversion Number for such Conversion Event and (y) upon such issuance, the Tax Distribution Arrearage for such Person shall be reduced by the Conversion Amount for such Conversion Event.

(b) Any distributions to the Members other than the distributions specified in Section 8.02(a), shall be made only if adopted by the Board as a dividend policy of the Company, subject to the rights of the Initial Members under Section 5.05 to approve any such distribution.

(c) The Company is authorized to withhold from payments and distributions, or with respect to allocations to the Members, any amounts required to be withheld under Law. All amounts withheld with respect to a Member shall be treated as if such amounts were distributed to such Member under this Agreement. Provided the Company determined the amount of any required withholding reasonably and in good faith, the Company shall not be liable for any over-withholding in respect of any Member’s Units, and, in the event of any such over-withholding, a Member’s sole recourse shall be to apply for a refund from the appropriate Governmental Authority. The Company shall cooperate with a Member in the preparation and filing of such refund claims.

(d) No Member has any right to demand or receive property from the Company other than cash.

(e) Notwithstanding anything in this Agreement to the contrary: (A) no distribution shall be made in violation of the Act or other applicable Law; and (B) except as provided in Section 8.02(a) or Section 13.05, all amounts distributed to the Members in respect of their equity interests in the Company shall be distributed to them pro rata in accordance with their respective Membership Percentages.

(f) The Members hereby consent and agree that, except as expressly provided herein or required by applicable Law, no Member shall have an obligation to return cash or other property paid or distributed to such Member under Section 18-502(b) of the Act or otherwise.

(a) Until the consummation of a Qualified IPO, no Member may Transfer, or permit or suffer to be Transferred, all or any part of its Units; provided , that (i) any Member may Transfer Units if such Transfer is approved in writing by the Initial Members in their sole discretion, (ii) any Member may Transfer Units if such Transfer is made by a Member to its Permitted Transferees (in the case of a natural Person holding Echo Shares, solely for bona fide estate planning purposes), (iii) any Member may Transfer Units if such Transfer is made pursuant to equity adjustments set forth in Section 2.03 and Section 8.06 of the Contribution Agreement, (iv) any Member may Transfer Units if such Transfer is in accordance with the provisions of Section 9.02 or Section 9.03, as applicable; provided further that in the event a transferee ceases to be a Permitted Transferee of the transferor, the transferee shall promptly Transfer such Units back to the Member or to another Permitted Transferee of the Member.

(b) The giving of an Initial Offer Notice to each non-Offeror Significant Member shall constitute an offer (the “ Initial Offer ”) by such Offeror to Transfer the Offered Units to each such Significant Member for cash at the Offer Price and on the terms set forth in the Initial Offer Notice. Each Significant Member receiving such Initial Offer Notice shall have a 30-day period (the “ Initial Offer Period ”) in which to accept such Initial Offer as to all of such Significant Member’s Offer Pro Rata Portion of the Offered Units by giving a notice of acceptance to such Offeror (together with a copy thereof to the Company) prior to the expiration of such Initial Offer Period. For purposes of this Section 9.02 only, “ Offer Pro Rata Portion ” means, with respect to a non-Offeror Significant Member, that fraction that results from dividing (i) the Membership Percentage of such non-Offeror Significant Member by (ii) the Membership Percentage of all non-Offeror Significant Members.

Initial Offer, informing them that they have the right to increase the number of Offered Units that they accepted pursuant to the Initial Offer to up to the number of Offered Units not subscribed for pursuant to the Initial Offer (the “ Second Offer ”). The accepting Significant Members shall then have five (5) Business Days (the “ Second Offer Period ”) in which to accept such Second Offer, by giving notice of acceptance to the Offeror prior to the expiration of such period (together with a copy thereof to the Company), as to all of the portion of the Offered Units not accepted pursuant to the Initial Offer. If more than one Significant Member accepts such Second Offer, then the Offered Units included in such Second Offer shall be allocated pro rata among the Significant Members accepting the Second Offer based on their relative Membership Percentages.

(d) If any non-Offeror Significant Members fails to notify the Offeror or the Company prior to the expiration of the Initial Offer Period or the Second Offer Period, as applicable, referred to above, it shall be deemed to have declined the Initial Offer or Second Offer, as applicable.

(e) If the non-Offeror Significant Members elect to purchase all the Offered Units, the Significant Members that have accepted the Initial Offer and/or the Second Offer shall purchase and pay, by wire transfer of immediately available funds to an account designated by Offeror, for all Offered Units within twenty (20) Business Days after the date on which the offer for all such Offered Units has been accepted; provided , that if the Transfer of such Offered Units is subject to any prior regulatory approval, the time period during which such Transfer may be consummated shall be extended until the expiration of five (5) Business Days after all such approvals shall have been received, but in no event shall such period be extended for more than an additional sixty (60) days; provided , that the time period may be further extended by sixty (60) days to complete any required financing; provided further , that, to the extent Echo is the Offeror, the holders of Echo Shares will be entitled, in the sole discretion of Echo, to substitute for any Unit to be Transferred by Echo in such ROFO Sale a number of Echo Shares equal to the Echo Ratio for the same consideration that would have otherwise been payable in respect of such Unit.

(f) If the non-Offeror Significant Members elect to purchase all the Offered Units, no Offeror shall be required to make representations or warranties in connection with such sale of Offered Units (other than with respect to title to the Offered Units being sold and customary due authority, no conflict and enforceability representations and warranties relating only to such Offerors which shall be made individually by such Offerors on a several basis).

(g) Upon the earlier to occur of (i) full rejection of the Initial Offer and, if applicable, the Second Offer by all recipients thereof, (ii) the expiration of the Second Offer Period without Significant Members electing, in the aggregate, to purchase all of the Offered Units, and (iii) the failure to obtain any required consent or regulatory approval for the purchase of all of the Offered Units by the Significant Members within 80 days of full acceptance of the Initial Offer or, if applicable, the Second Offer, the Offeror shall have a 120-day period (or a 365 day period in the case of a Drag-Along Sale) (the “ Marketing Period ”) during which to effect a Transfer of any or all of the

Offered Units on substantially the same or more favorable (as to the Offeror) terms and conditions as were set forth in the Initial Offer Notice at a price not less than the Offer Price; provided , that if the Transfer is subject to regulatory approval, the Marketing Period shall be extended until the expiration of five (5) Business Days after all such approvals shall have been received, but in no event shall such period be extended for more than an additional sixty (60) days. If the Offeror does not consummate the Transfer of the Offered Units in accordance with the foregoing time limitations, then the right of the Offeror to effect the Transfer of such Offered Units pursuant to this Section 9.02(g) shall terminate and the Offeror shall again comply with the procedures set forth in this Section 9.02 with respect to any proposed Transfer to a third party.

(h) The provisions of this Section 9.02 shall not apply to any Transfer of Units by a Member pursuant to Sections 9.01(a)(i), 9.01(a)(ii) or 9.01(a)(iii).

(a) If at any time during a Marketing Period, the Offerors (for the purposes of this Section 9.03, the “ Drag-Along Sellers ”) enter into a binding, definitive agreement complying with the terms of this Section 9.03 to Transfer all or substantially all of the Units (or Echo Shares) then outstanding (whether or not such Units (or Echo Shares) are held by the Drag-Along Sellers) to a third party (the “ Drag-Along Transferee ”) in connection with a Company Sale that was treated as a ROFO Sale and for which the Drag-Along Sellers had included in the Offer Notice a statement that such ROFO Sale would be a Drag-Along Sale (whether structured as a sale of Units (or Echo Shares), merger or other business combination) (a “ Drag-Along Sale ”), the Drag-Along Sellers may at their option require each other Member (each, a “ Dragged Member ”) to, (x) Transfer all (but not less than all) Units held by such Member (or Echo Shares, in the case Echo is the Dragged Member) to the Drag-Along Transferee for the same consideration (based on the pro rata Membership Percentages of the Members) and, (y) (1) vote such Dragged Member’s Units (and Echo Shares, in the case Echo is the Dragged Member) in favor thereof, and otherwise consent to and raise no objection to such Drag-Along Sale, and waive any dissenters’ rights, appraisal rights or similar rights that such Dragged Member may have in connection therewith and (2) be a party to the definitive agreement(s) governing the terms and conditions of such Drag-Along Sale on the same terms and conditions as the Drag-Along Sellers (except as provided in Section 9.03(c)); provided , that to the extent Echo is the Dragged Member, the holders of Echo Shares will be entitled, in the sole discretion of Echo, to substitute for the Units to be Transferred by Echo in such Drag-Along Sale all of Echo’s capital stock for the same consideration that would have otherwise been payable in respect of such Units.

(b) The Drag-Along Sellers shall provide notice of such Drag-Along Sale to the Dragged Members (a “ Drag-Along Sale Notice ”) not later than fifteen (15) days prior to the consummation of the proposed Drag-Along Sale.

If the consideration being paid in such Drag-Along Sale includes any non-cash consideration then, at the election of the Drag-Along Sellers (or with respect to itself, Echo or the MCK Members, to the extent it is a Dragged

Member), the Dragged Members shall receive either (i) their pro rata share of such non-cash consideration or (ii) cash (which cash may be paid by the Drag-Along Transferee or by the Drag-Along Sellers) in an amount equal to the Fair Market Value of their pro rata share of such non-cash consideration (in each case based on the aggregate consideration received by each of the Drag-Along Sellers in such Drag-Along Sale). Not later than five (5) Business Days after the date of the Drag-Along Sale Notice provided in connection with a Drag-Along Sale, each Dragged Member shall deliver to a representative of the Drag-Along Sellers designated in the Drag-Along Sale Notice (x) a limited power-of-attorney authorizing the Drag-Along Sellers or their representative to Transfer such Dragged Member’s Units (or Echo Shares) in accordance with the terms of this Agreement ( provided , that H&F shall not be obligated to deliver any power-of-attorney), the Drag-Along Sale Notice and the agreement(s) governing the terms and conditions of the Drag-Along Sale and (y) wire transfer or other instructions for payment or delivery of the consideration to be received by the Dragged Members in such Drag-Along Sale.

(f) Notwithstanding anything contained in this Section 9.03, there shall be no liability on the part of the Drag-Along Sellers to the Dragged Members (other than the obligation to return the limited power-of-attorney received by the Drag-Along Sellers (if applicable)) or any other Person if the Transfer of Units (or Echo Shares) pursuant to this Section 9.03 is not consummated for whatever reason, regardless of whether the Drag-Along Sellers have delivered a Drag-Along Sale Notice.

(g) The provisions of this Section 9.03 shall terminate upon the consummation of a Qualified IPO.

Section 9.04. Echo Stock Sales; No Asset or Unit Sales . Notwithstanding anything to the contrary in this Agreement, including but not limited to this Article 9 and Article 10, in any circumstances prior to the occurrence of a Qualified IPO in which Echo is entitled, permitted or required to Transfer Units (other than pursuant to Section 2.03 or Section 8.06 of the Contribution Agreement), including, but not limited to, pursuant to Section 9.02 or Section 9.03, Echo may require the proposed transferee and the other Members to structure such Transfer in a manner such that the Echo Shareholders transfer their Echo Shares in lieu of the Transfer by Echo of its Units to the proposed transferee. If the Echo Shareholders transfer their Echo Shares as described in this Section 9.04, each Echo Shareholder shall be entitled to substitute for any Unit a number of Echo Shares equal to the Echo Ratio for the same consideration that would have otherwise been payable in respect of such Unit.

(a) If the Members seek to determine the Fair Market Value of any Units (prior to a Qualified IPO) pursuant to the provisions of this Agreement referencing this Section 9.05, then Echo ( provided , that H&F shall have the right to negotiate Fair Market Value on behalf of Echo in the event that (i) the Sponsor Shareholder is not participating in a Transfer giving rise to such Fair Market Value determination or (ii) H&F shall have the right to receive all cash or marketable securities as consideration in the Transfer giving rise to such Fair Market Value determination) and the MCK Members shall negotiate in good faith for fifteen (15) days to determine the Fair Market Value of such Units, as applicable. If Echo and the MCK Members are not able to agree on the applicable Fair Market Value prior to such 15 ^th day, each shall select an Appraiser within five (5) Business Days thereafter. Within thirty (30) days after the selection of such Appraisers, each Appraiser so selected shall independently determine the Fair Market Value of such Units as of the date of notice of any sale or issuance requiring such determination of Fair Market Value (each, an “ Initial Appraised Value ”). If the two Initial Appraised Values differ from each other by 10% or less (based on the lower Initial Appraised Value), then the Fair Market Value of such Units shall be deemed to be the average of such Initial Appraised Values. If the two Initial Appraised Values differ from each other by more than 10% (based on the lower Initial Appraised Value), then the two initial Appraisers shall, within five (5) Business Days following such calculation, jointly select a third Appraiser. Within twenty one (21) days after the selection of such third Appraiser, such third Appraiser shall determine the Fair Market Value of such Units as of the date of notice of any sale or issuance requiring such determination of Fair Market Value, as applicable (the “ Subsequent Appraised Value ”), which Subsequent Appraised Value shall not be more than the greater of the two Initial Appraised Values nor less than the lower of the two Initial Appraised Values. If a third Appraiser is selected pursuant to this Section 9.05, the Fair Market Value of such Units shall be deemed to be the Subsequent Appraised Value.

(b) The Company shall provide each of the Appraisers with: (i) a copy of the pertinent sections of this Agreement, (ii) the Company’s most recent consolidated financial statements; (iii) financial forecasts (including documentation of the key assumptions used in such forecasts) for the Company and its Subsidiaries on a consolidated basis; and (iv) such other information as such Appraiser may reasonably request in connection with its appraisal. The Company shall provide each Appraiser with reasonable access to the Company’s management to discuss the financial information described in the preceding sub-clauses (ii) and (iii). In the event that the Company fails to comply with the obligations set forth in this Section 9.05(b) during the first fifteen (15) days of any applicable determination in this Section 9.05(b), such period shall be tolled until the Company complies with the obligations set forth in this Section 9.05(b).

(c) If the Members seek to determine the Fair Market Value of any Units following a Qualified IPO, then the Fair Market Value of such Units shall be determined by the Board based on the Echo Ratio and the arithmetic average of the VWAP of the Echo Shares over a thirty (30) consecutive trading day period immediately prior to the relevant determination date (or such shorter period of Trading Days following the date of

determination and the occurrence of a Qualified IPO). “ VWAP ” means, for each of the thirty (30) consecutive trading days during the 30-day averaging period, the per share volume-weighted average price of the Echo Shares as displayed by Bloomberg (or its equivalent successor) in respect of the period from the scheduled open of trading until the scheduled close of trading of the primary trading session on such trading day (or if such volume-weighted average price is unavailable, the market value of one share of the Echo Shares on such trading day determined, using a volume weighted average method, by a nationally recognized independent investment banking firm retained for this purpose by the Board). The volume weighted average price used for purposes of the VWAP will be determined without regard to after-hours trading or any other trading outside of the regular trading session trading hours.

(a) In connection with a Transfer of Units, each Person who becomes a record holder of Units in accordance with, and as permitted by, the terms of this Agreement, in each case who is not already a Member, shall, in addition to complying with the requirements of the last sentence of Section 14.06, execute and deliver this Agreement or a counterpart of this Agreement and agree in writing to be bound by the terms and conditions of this Agreement that were applicable to the Transferor (including the restrictions on Transfer contained in this Article 9), and shall thereupon be admitted as an additional Member of the Company (an “ Additional Member ”).

(c) A Transferee of Units who is admitted as an Additional Member accepts, ratifies and agrees to be bound by all actions duly taken pursuant to the terms and provisions of this Agreement by the Company on or prior to the date on which such Transferee was admitted as an Additional Member and, without limiting the generality of the foregoing, specifically ratifies and approves all agreements and other instruments that may have been executed and delivered on behalf of the Company on or prior to such date that are in force and effect on such date.

(d) Each Additional Member shall be named as a Member on Exhibit A . Unless and until admitted as an Additional Member, a Transferee of any Units, or a recipient of any newly issued Units or other Equity Securities of the Company, shall have no powers, rights or privileges of a Member of the Company.

(e) Following any Transfer of record ownership of Units in accordance with this Article 9, the Transferee thereof shall be treated as having made all of the Capital Contributions in respect of, and received all of the distributions received in respect of, such Units on or prior to the date of such Transfer, and shall receive allocations and

distributions in respect of such Units as if such Transferee had been a Member from the date of such Transfer. The distributive share of the Company’s income, gains, losses, deductions, credits and other items of a Member whose interest is disposed of, in whole or in part, shall be determined by the Board using any permissible method under Section 706 of the Code and the Treasury Regulations thereunder.

A Transfer of any record ownership of Units shall be effective upon registration of the Transfer in the books of the Company.

Section 9.07. Termination of Member Status. Any Member that Transfers all of its, and owns no, Units in the Company shall immediately cease to be a Member and shall no longer be a party to this Agreement (in its capacity as a Member) and Exhibit A shall be updated to eliminate such Person; provided , that such Member (a) shall not thereby be relieved of liability for any breach of this Agreement prior to such time or from any obligation under this Agreement other than its capacity as a Member; (b) shall retain any rights with respect to any breach of this Agreement by any other Person prior to such time; (c) shall retain the right to indemnification in accordance with the terms hereof; and (d) shall not thereby be relieved of any of its obligations under Section 7.04(h) and this Article 9.

Section 9.08. Void Transfers. To the greatest extent permitted by the Act and other Law, any Transfer made or permitted by any Member of all or any portion of its equity interest in the Company (including, for the avoidance of doubt, any Transfer of any Units, or any equity interests in any Member or other Person that directly or indirectly owns Units) in contravention of this Agreement shall be ineffective and null and void ab initio , and shall not bind or be recognized by the Company or any other Person. In the event of any Transfer in contravention of this Agreement, to the greatest extent permitted by the Act and other Law, the purported Transferee shall have no right to any profits, losses or distributions of the Company or any other rights of a Member.

(a) As soon as practicable, but in any event within thirty (30) days after the Closing, the Company shall cause the Board to create a special committee which shall include an equal number of MCK Directors and Echo Directors (the “ IPO Committee ”) which shall oversee the conduct and consummation of a Qualified IPO.

The engagement of the underwriters shall be on financial and other terms customary in the industry, and all fees and expenses shall be borne by the Company (other than underwriting discounts and commissions which shall be payable by Echo). The Company agrees and acknowledges that it will be the indemnitor of first resort with respect to the Qualified IPO.

(b) In connection with the conduct and consummation of a Qualified IPO, the Company and each of the Initial Members shall cooperate in good faith and use their reasonable best efforts to consummate the Qualified IPO as promptly as practicable, but in no event later than eighteen (18) months from the Closing (“ QIPO Deadline ”), provided , that the QIPO Deadline may be extended by the IPO Committee based on the advice of the underwriters that prevailing market and/or industry conditions do not support the conduct and consummation of a Qualified IPO and the Company and the Members shall use reasonable best efforts to consummate a Qualified IPO once such conditions are no longer in effect, but not longer than the Initial Period. In furtherance of the QIPO Deadline (and unless extended pursuant to the preceding sentence), Echo shall make an initial filing of a registration statement on Form S-1 relating to the Qualified IPO (the “ Registration Statement ”) on or prior to twelve (12) months from Closing and thereafter use its reasonable best efforts to prepare and file amendments to the Registration Statement that are reasonably required to (i) appropriately respond to comments received from the SEC relating to such Registration Statement and (ii) otherwise keep the Registration Statement current (including with respect to the financial statements and other financial and other information required by the rules and regulations of the SEC to be included therein). Echo and each of the parties agree they will reasonably consult, and keep each other reasonably informed, and that each party will have the right to participate in the drafting and preparation of any Registration Statement and any amendments thereto, including responses to any comments received from the SEC. Subject to Section 10.01(c), each of the MCK Members and Echo shall have the right to participate equally in the preparation of the Registration Statement and any amendments thereto and otherwise to participate equally in the Qualified IPO process.

(c) If a Qualified IPO has not been consummated within twenty four (24) months following the Closing (such 24-month period, the “ Initial Period ”), then, notwithstanding any other provision to the contrary set forth herein, each of the MCK Members and Echo shall have the right to cause Echo, the Company and the other Members to conduct and consummate a Qualified IPO within the IPO Preference Period, and thereafter the MCK Members shall have the right to conduct a Qualified MCK Exit within the MCK Exit Window following such Qualified IPO. Following the IPO Preference Period, each of the MCK Members and Echo shall have the right to cause the Company and the other Members to conduct and consummate a Qualified IPO; provided , that if a Member has delivered an Initial Offer Notice for a ROFO Sale that constitutes a Drag-Along Sale, then neither the Company nor Echo shall conduct a Qualified IPO from the date of delivery of the Initial Offer Notice through the Marketing Period relating to such Drag-Along Sale without the consent of the Drag-Along Sellers. In order to exercise the right to cause or conduct a Qualified IPO pursuant to this Section 10.01(c), the MCK Member or Echo, as the case may be (in either case, the “ IPO Demanding Party ”), shall be entitled, in its sole discretion, to deliver a written notice to the Company and to the other Initial Members (an “ IPO Demand ”) notifying the Company and the other Initial Members of the IPO Demanding Party’s exercise of an IPO Demand. Upon receipt of such IPO Demand (which, in the case of a Qualified IPO to be consummated

during the IPO Preference Period, shall be delivered no later than on the date that is ten (10) Business Days following the expiration of the Initial Period), the Company and Echo shall effect a Qualified IPO as soon as practicable, but in any event within six (6) months after receipt of such IPO Demand (and in the case of a Qualified IPO to be consummated during the IPO Preference Period, prior to the expiration of such period). Upon receipt of an IPO Demand, the IPO Committee and each of the Initial Members and the Company shall cooperate with each other in the conduct and consummation of such Qualified IPO, including providing access to the documents, records and senior management of the Company, procuring the participation of senior management in investor road-shows and similar marketing efforts, and executing and delivering any documents reasonably requested by the IPO Committee or any underwriter to the Qualified IPO.

In connection with the consummation of a Qualified IPO, (a) the number of outstanding Echo Shares shall be adjusted by way of stock split or reverse stock split and (b) the number of Units shall be adjusted by way of a Unit split or reverse Unit split, in each case to the extent necessary to cause (x) the number of outstanding Echo Shares to be equal to the number of Units held by Echo and (y) each of the Echo Shares sold to the public in the Qualified IPO and the price per share of such Echo Shares (calculated before giving effect to any underwriting discounts and commissions) to be within the range recommended to the Company by the underwriters, in the case of both (x) and (y), upon consummation of the Qualified IPO. Each of the Members and the Company shall cooperate with each other to implement the adjustments described in the preceding clauses (a) and (b).

(a) Following consummation of a Qualified IPO occurring at any time prior to the expiration of the IPO Preference Period, and upon the expiry of any customary lockup period required by the underwriters in connection with the consummation of a Qualified IPO, (i) each MCK Member and its Affiliates shall have the right to conduct and consummate a Qualified MCK Exit during the MCK Exit Window (in accordance with the process set forth in Section 10.05 below) and (ii) (a) the Echo Shareholders as determined by the Sponsor Shareholder shall have the right to conduct and consummate a Qualified Echo Sale during the First Echo Sale Window and (b) the Echo Shareholders shall have the right to consummate one or more Qualified Echo Sales during the Second Echo Sale Window, in each case pursuant to the Registration Rights Agreement and Section 10.03(b) hereof (the “ Echo Shareholder Sale Right ”), which Qualified Echo Sales shall be subject to the Tag-Along Rights of the MCK Members set forth in the Registration Rights Agreement. Each of the Company and each of the Initial Members shall use their reasonable best efforts to cooperate in good faith to consummate any Qualified MCK Exit and any Qualified Echo Sale as promptly as practicable.

or (D) any combination thereof, provided , that in all cases the shareholders and debtholders of MCK receive 75% or more of the stock of SpinCo as a consequence thereof, and (iii) substantially contemporaneously with the consummation of the Exchange Offers, the Spin-Off and/or the Non-Stock Exchanges, SpinCo will be merged with and into Echo, with Echo as the surviving corporation in such merger (the “ Merger ”) pursuant to the Merger Agreement entered into as of [●] by and between SpinCo and Echo (as such may be amended by the parties thereto from time to time) (the “ Merger Agreement ”), pursuant to which each share of SpinCo stock outstanding immediately prior to the effective time of the Merger will be converted into the right to receive a number of Echo Shares (rounded to the nearest ten-thousandth of a share) (such number, the “ Exchange Ratio ”) determined by dividing the number of Units then held by the MCK Members or their Permitted Transferees by the number of outstanding shares of SpinCo common stock. In the event that the Merger Agreement is terminated or otherwise fails to be consummated other than as a result of a breach thereof by SpinCo, the parties shall use commercially reasonable efforts to cooperate with each other to agree upon and execute a mutually agreeable merger agreement to consummate the transactions contemplated by this Section 10.05.

In the event of a change in law or regulation following the date of signing of the Contribution Agreement that is or is believed by any of the parties hereto to be relevant to the interpretation or effect of the Tax Matters Agreement (including any change in law or regulation expressly referenced therein), the parties will use reasonable best efforts to agree upon such changes to such form as may be necessary or advisable so as to give effect to the original intent, purposes and effect of such form (based on law and regulation in effect as of the date of signing of

the Contribution Agreement) as nearly as practicable without altering the respective rights or obligations of the parties, or otherwise adversely affecting any party in any non-de minimis respect.

(e) Echo will use commercially reasonable efforts to (A) twenty-one Business Days prior to the beginning of a Qualified MCK Exit, deliver to Parent a statement setting forth Echo’s good faith estimate of the aggregate number of shares of Echo expected to be received in the Merger (by virtue of having received shares of SpinCo stock in the Exchange Offers or the Spin-Off) by (i) Blackstone (as defined in the Tax Matters Agreement), (ii) any Person Under the Control of Blackstone (as defined in the Tax Matters Agreement), (iii) any Person that has acquired or will acquire stock of MCK in one or more coordinated acquisitions or dispositions of the stock of MCK with any Person described in clauses (i) or (ii), (iv) H&F (as defined in the Tax Matters Agreement), (v) any Person Under the Control of H&F (as defined in the Tax Matters Agreement) and (vi) any Person that has acquired or will acquire stock of MCK in one or more coordinated acquisitions or dispositions of the stock of MCK with any Person described in clauses (iv) or (v) and (B) update such schedule to reflect any changes between the date such schedule is delivered and the time of the Merger, it being understood that any failure of information included in such schedule, or any update thereto, to be accurate shall not constitute a breach of this Agreement or an Echo Disqualifying Action for purposes of the Tax Matters Agreement.

(a) The Company hereby grants to MCK and each of the MCK Members and their Affiliates an irrevocable option, exercisable at any time during the MCK Exit Window and prior to consummation of a Qualified MCK Exit, to purchase from the Company (whether directly or indirectly, including through the purchase of Units by SpinCo) additional Units (the “ Top-up Units ”, and such option, the “ Top-up Option ”), such that following exercise of the Top-up Option, the shareholders of MCK shall be entitled to hold such number of Echo Shares that, when added to the number of Echo Shares that would be owned by the shareholders of MCK at the effective time of the Merger, constitutes at least one Echo Share more than 50% of the Echo Shares that would be outstanding immediately after the issuance and/or sale of all Echo Shares upon exercise of the Top-up Option, calculated on a fully-diluted basis. For the avoidance of doubt, the Top-up Option granted to MCK and each of the MCK Members is non-transferrable other than to Permitted Transferees.

(b) The Top-up Option may be exercised by the MCK Members or their Affiliates only during the MCK Exit Window, and only if the MCK shareholders shall own, in the absence of exercise of the Top-up Option, at the effective time of the Merger, 50% or less of the Echo Shares outstanding on a fully-diluted, post-Merger basis. The aggregate purchase price payable for the Top-up Units being purchased by MCK, SpinCo or the MCK Members or their Affiliates pursuant to the Top-up Option shall be determined by multiplying the number of such Top-up Units by the Fair Market Value of each Top-up Unit, as determined in accordance with the valuation and appraisal process set forth in Section 9.05, without interest. The purchase price must be paid by MCK (or its Affiliate) in cash.

(a) In the event of the dissolution of the Company pursuant to Section 13.02, the Company’s affairs shall be wound up by a liquidating trustee of the Company selected by the Board (in such capacity, the “ Liquidating Agent ”), which Liquidating Agent shall be an individual who is knowledgeable about the Company’s business and operations (to the extent possible) and has substantial experience in the purchase and sale of businesses.

(b) Upon dissolution of the Company and until the filing of a certificate of cancellation as provided in Section 18-203 of the Act, the Liquidating Agent may, in the name of, and for and on behalf of, the Company, prosecute and defend lawsuits, whether civil, criminal or administrative, settle and close the Company’s business, dispose of and convey the Company’s property or sell the Company (and its Subsidiaries) as a going concern, discharge or make reasonable provision for the Company’s liabilities, and distribute to the Members in accordance with Section 13.05 any remaining assets of the Company, all without affecting the liability of Members and without imposing any liability on any Liquidating Agent.

(c) Except as otherwise provided in this Agreement, the Members shall continue to share distributions and allocations during the period of liquidation in the same manner as before the dissolution.

(d) A reasonable time period shall be allowed for the orderly winding up and liquidation of the assets of the Company and the discharge of liabilities to creditors so as to enable the Liquidating Agent to seek to minimize potential losses upon such liquidation. Subject to the provisions of Section 13.05 and Section 13.06, the Liquidating Agent shall have reasonable discretion to determine the time, manner and terms of any sale or sales of the Company’s property pursuant to such liquidation. The provisions of this Agreement shall remain in full force and effect during the period of winding up and until the filing of a certificate of cancellation of the Company with the Secretary of State of the State of Delaware.

(e) Upon the completion of the winding up of the Company, the Liquidating Agent or other duly designated representative shall file a certificate of cancellation of the Company with the Secretary of State of the State of Delaware as provided in Section 18-203 of the Act.

(ii) second, to the Members pro rata in accordance with their respective positive Capital Account balances (after giving effect to any allocations of income, gain, deduction or loss pursuant to Section 8.01(a) and Section 8.01(b)).

(b) The Liquidating Agent shall have the power to establish any reserves that, in accordance with sound business judgment, it deems reasonably necessary to pay all claims and obligations, including all contingent, conditional or unmatured claims and obligations, which reserves may be paid over to an escrow agent selected by the Liquidating Agent to be held by such agent for the purpose of paying out such reserves in payment of the aforementioned contingencies and upon the expiration of such period as the Liquidating Agent may deem advisable, making a distribution of the balance thereof to the Members in the manner provided in this Section 13.05.

(a) In the event of the dissolution of the Company pursuant to Section 13.02, prior to entering into any agreement providing for any sale or transfer of the Patent Rights owned by the Company or its Subsidiaries (the “ Company Owned Patent Rights ”), the Liquidating Agent shall deliver a written notice to MCK indicating (i) its desire to sell or transfer any such Company Owned Patent Rights, (ii) the cash price that the Liquidating Agent proposes to be paid for such Company Owned Patent Rights and in reasonable detail any other material terms and conditions sought by the Liquidating Agent. The delivery of such notice shall constitute an offer by the Liquidating Agent to transfer such Company Owned Patent Rights to MCK (or its designee) for cash at the price set forth in such notice and on any terms and conditions set forth therein.

(b) MCK may accept or reject any such offer delivered by the Liquidating Agent, in its sole discretion, by delivering a written notice of MCK’s acceptance or rejection, as the case may be, to the Liquidating Agent within thirty (30) calendar days after receipt of written notice thereof. If MCK accepts any such offer, then the Liquidating Agent and MCK (or its designee) shall promptly and in good faith enter into a written definitive agreement setting forth the terms of the transfer. In the event that MCK does not accept any such offer within such thirty (30) calendar day period, then the Liquidating Agent shall be free to negotiate an agreement with any other Person for the

sale of any such Company Owned Patent Rights on substantially similar (or, from the perspective of the Company, better) terms and conditions as those contained in any offer delivered to MCK hereunder.

(c) If MCK fails to exercise its right to accept such offer as provided herein or if the Liquidating Agent fails to execute a definitive agreement with such other Person on the terms and conditions set forth in the aforementioned written offer delivered by the Liquidating Agent to MCK within three hundred and sixty (360) days of the date on which MCK rejected or failed to exercise its right to accept such offer as set forth in subsection (b) of this Section 13.06, then the Liquidating Agent shall be required to submit a new offer to MCK (and repeat the process set forth in this Section 13.06(b)) before entering into a definitive agreement with any other Person with respect to any such Company Owned Patent Rights.

(d) The provisions of this Section 13.06 shall only apply in the event of the dissolution of the Company pursuant to Section 13.02 prior to a Qualified MCK Exit and immediately upon consummation of a Qualified MCK Exit, the provisions of this Section 13.06 shall terminate.

Section 13.07. Distributions in Cash or in Kind. Upon the dissolution of the Company, the Liquidating Agent shall use all commercially reasonable efforts to liquidate all of the Company assets in an orderly manner and apply the proceeds of such liquidation as set forth in Section 13.05; provided , that if in the good faith judgment of the Liquidating Agent, a Company asset should not be liquidated, the Liquidating Agent shall distribute such asset, on the basis of its value (determined in good faith by the Liquidating Agent), in accordance with Section 13.05, subject to the priorities set forth in Section 13.05; and provided, further , that the Liquidating Agent shall in good faith attempt to liquidate sufficient assets of the Company to satisfy in cash (or make reasonable provision for) the debts and liabilities referred to in Section 13.05(a)(i).

Section 13.08. Claims of the Members. The Members and former Members shall look solely to the Company’s assets for the return of their Capital Contributions, and if the assets of the Company remaining after payment of or due provision for all debts, liabilities and obligations of the Company are insufficient to return such Capital Contributions, the Members and former Members shall have no recourse against the Company, any Director or any other Member. No Member shall have any obligation to make any Capital Contribution with respect to such insufficiency, and such insufficiency shall not be considered a debt owed to the Company or to any other Person.

Section 14.01. Further Assurances.

(c) Notwithstanding Sections Section 14.02(a) and 14.02(b), the Board may, subject to Section 5.05, amend, without the consent of the Members:

(i) this Agreement solely in order to reflect the fact that a new Member admitted in accordance with the terms of this Agreement has agreed to become bound by, and subject to, this Agreement;

Except as otherwise specifically provided herein, any party may waive any right of such party under this Agreement by an instrument signed in writing by such party.

Furthermore, the parties expressly agree that if any of the parties hereto, or the Company, institutes any action or proceeding to enforce the provisions hereof, any other party against whom such action or proceeding is brought shall be deemed to have expressly, knowingly, and voluntarily waived the claim or defense that an adequate remedy exists at law. Each party hereby waives any requirement of any posting of bond.

Section 14.09. Governing Law. This Agreement and all related disputes shall be governed by and construed in accordance with the provisions of the Act, and other applicable Laws of the State of Delaware, without regard to its conflicts of law principles.

(a) Subject to Section 14.10(b) below, for the purposes of any suit, action or other proceeding arising out of or relating to this Agreement, each party to this Agreement irrevocably submits, to the fullest extent permitted by Law, to the exclusive jurisdiction of the Chancery Court of the State of Delaware (or if unavailable, any federal court sitting in the State of Delaware or, if unavailable, the Delaware Superior Court) and the appellate courts having jurisdiction of appeals in such courts.

The parties hereto agree that a final judgment in any such suit, action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

(b) At any time prior to a Qualified MCK Exit, any dispute arising out of or relating to this Agreement shall first be escalated to the Ad Hoc Committee that will be formed upon notice by the party wishing to resolve the dispute.

This TRANSITION SERVICES AGREEMENT (this “ Agreement ”), dated as of [●], 2016, is made by and between McKesson Corporation, a Delaware corporation (“ MCK ”) and PF2 Newco LLC, a Delaware limited liability company (“ NewCo ”). Capitalized terms used in this Agreement but not otherwise defined in this Agreement have the meaning assigned to such terms in the Contribution Agreement (as defined below).

WHEREAS, MCK and NewCo have entered into that certain Agreement of Contribution and Sale, dated June 28, 2016, among NewCo, PF2 NewCo Intermediate Holdings, LLC, PF2 NewCo Holdings, LLC, MCK, HCIT Holdings, Inc., Change Healthcare, Inc., Change Aggregator L.P., H&F Echo Holdings, L.P. and the other equityholders of Change Healthcare, Inc. set forth therein (the “ Contribution Agreement ”) and related Transaction Documents with respect to the contribution and/or sale to NewCo of the Echo Business and the Core MTS Business by Echo and MCK, respectively;

WHEREAS, MCK desires to provide to NewCo certain transition services to support the Core MTS Business after the Closing, and NewCo desires to accept such transition services from MCK upon the terms and conditions in this Agreement; and

WHEREAS, MCK and NewCo desire to enter into this Agreement, to be effective on the Closing Date, as further set forth in this Agreement.

1.1 Services in General . Commencing on the Closing Date, MCK will provide, or cause its Affiliates to provide, to NewCo the transition services specified in the service schedule attached hereto as Exhibit A (“ Service Schedule ”) in accordance with and subject to the terms and conditions of this Agreement and the Service Schedule (such services are referred to, collectively, as the “ Services ” and each, individually, as a “ Service ”). Subject to Section 1.3, MCK’s obligation to provide services under this Agreement is limited to the provision of the Services described in this Agreement through the end date of the service period for each Service as set forth in the Service Schedule.

1.2 Level of Services . Unless expressly set forth otherwise in the Service Schedule and subject to the terms and conditions hereof, MCK will provide, or cause to be provided by its Affiliates, the Services in substantially the same manner scope, content and quality standard and at substantially the same level as such or similar Services were performed by MCK for the Core

MTS Business during the twelve months prior to the Closing Date. To the extent that MCK fails to meet such service level standards with respect to any Services notwithstanding that MCK is exercising commercially reasonable efforts, MCK will ensure that the Core MTS Business is not adversely discriminated against as compared to MCK’s other business units for which MCK is performing comparable Services.

1.3 Omitted Services . If, at any time within six months following the Closing Date, NewCo becomes aware of any service that had been provided in the ordinary course during the six months prior to the Closing Date by MCK or its Affiliates to the Core MTS Business that is not included in the Service Schedule and which (a) is not provided to NewCo pursuant to another agreement between MCK and NewCo or their respective Affiliates (and that the parties had not otherwise expressly agreed would not be provided), (b) is reasonably necessary for NewCo to conduct the Core MTS Business in substantially the same manner as provided during the twelve-month period prior to the Closing Date and (c) has not been discontinued by MCK for all of its other business units, then upon written notice from NewCo and subject to (1) Applicable Law, (2) any applicable restrictions in third-party agreements to which MCK is a party and (3) MCK’s internal policies and procedures (so long as such policies and procedures are not implemented by MCK for the purpose of or have the effect of (except to the extent such effect is a result of NewCo being a bad actor) disproportionately discriminating against NewCo), the parties shall negotiate in good faith an amendment to the Service Schedule in order to address the terms for such service as a Service, including negotiating the Service Fees (to be calculated at cost, consistent with MCK’s allocated cost or pass-through charges from third-parties consistently applied across MCK’s business units) for such Service. If MCK has not notified NewCo of the discontinuation of a service that it provides for all of its other businesses, and such discontinuation would disproportionately affect the Core MTS Business as operated prior to the Closing compared to MCK’s other businesses, subsection (c) of this Section 1.3 will not be a basis for not providing such Omitted Service under this Agreement.

1.4 Project Managers . Each party will designate a project manager (“ Project Manager ”) who will (a) serve as such party’s primary representative under this Agreement, (b) have overall responsibility for managing and coordinating the performance of such party’s obligations under this Agreement and be responsible for the day-to-day implementation of this Agreement, including attempted resolution of any issues that may arise during the performance of any party’s obligations hereunder for each of the Services, (c) be authorized to act for and on behalf of such party with respect to all matters relating to this Agreement and (d) will provide guidance on the steps the parties shall take to cooperate in the transition, separation and migration of the Services. Generally, requests by NewCo relevant to the Services will be made by NewCo’s Project Manager to MCK’s Project Manager; however , the foregoing provision will not limit either party’s ability to communicate with the other party’s relevant contact person(s) with respect to any particular Service. Either party’s Project Manager may from time to time designate a substitute of commensurate skills and experience by notice to the other party to fulfill such Project Manager’s responsibilities during any periods of unavailability.

1.5 Steering Committee . A TSA governance structure with functional service teams, Project Managers and an oversight steering committee shall be established as outlined in Exhibit B .

Each party will designate two representatives to serve on a committee (the “ TSA Steering Committee ”), which will resolve matters brought before it by the Project Managers. One representative designated by each party shall be an executive-level officer of such party (the “ Executive Sponsor ”) and each Executive Sponsor shall serve as a co-chairman of the TSA Steering Committee. The TSA Steering Committee shall meet monthly, or at such time as mutually agreed upon by the parties and at such place as mutually agreed upon by the parties.

1.6 Cooperation . The parties agree to reasonably cooperate with each other in good faith in connection with the provision and receipt of the Services. NewCo will provide MCK with such assistance and cooperation as is reasonably necessary in order for MCK or its contractors or Affiliates to timely perform the Services and such other assistance and cooperation as MCK may reasonably request (collectively, “ Cooperation ”). MCK will have no liability for any failure to perform (or to timely perform) its obligations to the extent such failure solely results from NewCo’s failure to provide Cooperation, and MCK’s failure in such circumstances will not be deemed a breach of this Agreement.

1.7 Affiliates and Subcontractors . In providing the Services, MCK may use personnel of MCK and/or its Affiliates, and/or engage the services of other third-parties to provide or assist MCK (or its Affiliates) in the provision of the Services. MCK will remain responsible for any Services performed by its Affiliates or such other third-parties and MCK’s use of an Affiliate or other subcontractor will not relieve MCK of its obligations under this Agreement. The use of a new third-party to provide a Service, who had not previously provided an applicable Service to the Core MTS Business prior to Closing, shall require NewCo’s consent (including directly entering a HIPAA-compliant business associate agreement with NewCo if necessary), such consent not to be unreasonably withheld.

1.8 Segregation Services; Efforts to End Dependency . After the Closing Date, the TSA Steering Committee will review transition plans prepared jointly by the operations teams of both parties and approve a proposed timeline for transitioning each of the Services to NewCo, new service providers or, by mutual agreement, determining that some Services should be provided on a long-term basis by MCK. The parties will use commercially reasonable efforts to ensure that such separation timelines are met. For Services that will be sourced on a long-term basis from MCK, the parties will negotiate and enter into, during the term of this Agreement, a master services agreement for such Services on commercially reasonable terms and conditions. As set forth in the Exhibit A Addendum , NewCo will be responsible for the development of transition plans and MCK will provide reasonable assistance with respect to the development of such plans and separation efforts. Each party will provide the other party in a timely fashion with all relevant information, policies, procedures, methods of operation and other data reasonably requested by such other party for the separation. MCK will use commercially reasonable efforts to obtain consents for services, systems and software to be provided under this Agreement. To the extent that MCK provides segregation Services hereunder, namely those Services relating to the segregation of the Core MTS Business from MCK ( e.g. , providing current stated data schema and configuration details in the existing format (without customization or manipulation), providing asset inventory and available associated diagrams and configurations, setting up a separate instance of SAP in a manner reasonably determined by the

TSA Project Managers, cloning and providing copies of proprietary transferrable software and data (without customization or manipulation), data extraction and segregation of data (without manipulation) including removal of MCK’s data from NewCo’s systems and NewCo’s data from MCK’s systems, and testing/acceptance support), MCK acknowledges that, except as otherwise provided herein, such steps shall be undertaken at MCK’s own cost, including with respect to any third-party costs (it being understood that, notwithstanding the foregoing, the cost associated with the migration and integration, namely those Services relating to the building and implementation necessary for NewCo to operate as a combined business ( e.g. , creation of new or modified systems with all data necessary to run transitioned NewCo Systems, data conversion, configuration management, porting of data from MCK to NewCo in NewCo’s required format) shall be paid by NewCo). Upon NewCo’s reasonable request, for shared information technology agreements with third-parties which are not included in the MCK Contributed Assets where the vendor will, upon request, divide the license, MCK and NewCo shall work together and exercise commercially reasonable efforts to cause the portions of such licensed units that have been primarily used by the Core MTS Business to be assigned to NewCo under an enterprise or other agreement with the relevant information technology vendor. For the avoidance of doubt, entry into a new enterprise or other agreement with such vendor shall be the responsibility of NewCo. Subject to the foregoing, if requested, MCK shall provide requisite assistance as is reasonably requested by NewCo for exit of the Services at no additional charge.

1.9 Migration . MCK shall provide all requisite assistance as is reasonably requested by NewCo in order to migrate the Services from MCK’s personnel, facilities and environment to NewCo’s (or its designee’s) personnel, facilities and environment, provided , that, other than as expressly set forth in the Service Schedule, NewCo shall be responsible for all third-party costs incurred by MCK and its Affiliates to migrate such Services and, provided further , that, NewCo shall be responsible for all costs associated with operational decisions made by NewCo for its set-up costs and costs to procure items ( e.g. , selection of Customer Relationship Management software). For the avoidance of doubt, NewCo will be responsible for migration to any new NewCo Data Center, including design, implementation and testing. MCK will provide reasonable support in such efforts. MCK will provide to NewCo an electronic copy in the then-current format of all data that is owned by NewCo (a) a written description of processes and procedures used by MCK in connection with the provision of Services to the Core MTS Business to the extent such descriptions exist, (b) a written description of all system documentation, architecture diagrams and business process diagrams for the systems, processes and controls used in the Core MTS Business to the extent such descriptions exist and (c) written training and onboarding materials used in the Core MTS Business to the extent such materials exist. In addition, MCK will, upon NewCo’s reasonable request, make available knowledgeable MCK personnel for knowledge transfer and discussion at a mutually agreed upon time with respect to the Services and the processes, procedures and systems used in the provision of the Services. The parties will meet in person to establish, within two (2) weeks following the Closing Date, a planning process for the migration of the Services from MCK’s personnel, facilities and environment to NewCo’s (or its designee’s) personnel, facilities and environment. During such meetings, the parties will identify workstreams and workstream leaders, staff project teams for each workstream, identify roles and responsibilities for project team members and create a project charter that will serve collectively as the basis for developing more detailed timelines and specific deliverables for each of the workstreams. At a minimum, there will be a workstream for each functional area that is the subject of Schedules. Each workstream will report to the Project Managers. The parties will meet (in person or by telephone) as often as is reasonably necessary to develop such detailed timelines and specific deliverables for each workstream.

1.10 MCK’s Obligations . Notwithstanding anything to the contrary in this Agreement, MCK will not be required to perform any Service if doing so would require MCK to (a) hire any new employees, consultants or other personnel (it being understood that, for the avoidance of doubt, employees, consultants or other personnel hired to replace employees, consultants or other personnel who may have departed or otherwise been redeployed by MCK shall not be considered “new” for purposes of the foregoing), (b) violate any Applicable Law or MCK internal compliance policies or procedures (so long as such policies and procedures are not implemented by MCK for the purpose of or have the effect of (except to the extent such effect is a result of NewCo being a bad actor) disproportionately discriminating against NewCo) or (c) breach any contract by which MCK is bound, provided, that MCK will undertake good faith, commercially reasonable efforts, with NewCo’s reasonable cooperation, to obtain a waiver or third-party consent if necessary to perform such Service. In addition and without limiting the foregoing, if the performance of a particular Service requires MCK and its Affiliates to obtain any additional third-party licenses or consents, or any software, technology or other goods, services or materials that are neither in MCK’s possession nor included in the Service Fees, then MCK may so inform NewCo’s Project Manager, and if NewCo does not agree to pay actual costs for such items (with the parties consulting with each other on ways to minimize such costs), MCK will be excused from its obligation to perform the applicable Services to the extent such items are required. To the extent that NewCo directly pays a third-party the actual costs for such items, any Service Fees that were calculated assuming that MCK would be paying such costs shall be adjusted accordingly.

1.11 Third-Party Licenses . With respect to any third-party licenses or services made available to NewCo or its Affiliates in connection with any Services, NewCo and its Affiliates agree to comply with the terms applicable to such license(s) and/or service(s) to the extent provided to its Project Manager in advance. NewCo will be responsible for any additional fees imposed by any such third-party related to Services provided during the term of this Agreement and any breach of such terms by NewCo or its Affiliates to which its Project Manager was made aware of such terms in advance and shall indemnify MCK pursuant to Section 6.1 for any Damages (as defined in Section 6.1) arising from NewCo or its Affiliates’ failure to so comply with such terms to which its Project Manager was made aware of such terms in advance. Except as expressly set forth in this Agreement, the prices for Services set forth in the IT Services Schedule of Exhibit A factor in the cost of third-party licenses required to provide Services under this Agreement.

2.1 Service Fees and Expenses . NewCo will pay each month (unless otherwise set forth in the Service Schedule with respect to any Service) to MCK the fees specified for each Service rendered during such month as set forth on the Service Schedule (“ Service Fees ”). The

indicated Service Fees are calculated for MCK to provide the Services at cost, consistent with MCK’s allocated cost or pass-through charges from third-parties consistently applied across MCK’s business units. Except as the parties may otherwise agree, the Service Fees for the Services shall be consistent with the prices contemplated for Services in the Day 1 TSA Cost Structure shared with Change Healthcare, Inc. prior to the signing of the Contribution Agreement (it being understood that the foregoing shall not apply to the extent there are any increases in any third-party costs). Except as expressly set forth in this Agreement, all Service Fees are nonrefundable. MCK will be entitled to reimbursement for any reasonable out-of-pocket travel-related additional costs or expense for transportation, accommodations or other travel-related expenses, where such travel has been pre-approved by NewCo, incurred in connection with the performance of the Services. Such travel-related expenses will follow MCK’s then-current corporate travel policy. If MCK agrees to provide any services other than the Services described in this Agreement, such services will be provided on a time and materials basis at MCK’s standard rates then in effect for such services, with fees and expenses therefor invoiced by MCK to NewCo on a monthly basis and paid in accordance with this Article 2. For the avoidance of doubt, to the extent NewCo is required, due to a Force Majeure Event (as defined below), to engage a third-party service provider to provide replacement Services, the amount payable to MCK hereunder shall be reduced by the Service Fees attributable to such Services but not below zero.

2.2 Payment Terms . On or after the last day of each calendar month, MCK will invoice NewCo for the Service Fees and reimbursable expenses due under this Agreement for the Services rendered during such month, provided , that failure to timely invoice will not preclude later invoicing and collection of amounts payable. NewCo will pay the invoiced amounts within forty-five (45) days of receipt of the invoice, except for amounts subject to a bona-fide and good faith dispute with respect to which NewCo has provided written notice to MCK, including a detailed description of the basis for the dispute, prior to the date such amounts were due (a “ Dispute ”). Payment will be made by wire transfer of immediately available funds to an account specified in writing by MCK.

2.3 Transfer Taxes . The Service Fees are exclusive of any sales, use, excise, value-added or similar taxes that are imposed on the provision of the Services by any federal, state, municipal, or other U.S. or foreign taxing authority (“ Transfer Taxes ”). MCK will separately list any such taxes on the applicable invoices and NewCo will be responsible for and pay such taxes. MCK shall take commercially reasonable actions to cooperate with NewCo in obtaining any refund, return, rebate, or the like of any Transfer Tax, including by filing any necessary exemption or other similar forms, certificates, or other similar documents, in each case only to the extent that MCK is legally entitled to do so. NewCo shall promptly reimburse MCK for any out-of-pocket costs incurred by MCK in connection with NewCo obtaining a refund, return, rebate, or the like of any Transfer Tax. If MCK receives any refund (whether by payment, offset, credit or otherwise), or utilizes any overpayment, of Transfer Taxes, then MCK shall promptly pay, or cause to be paid, to NewCo the amount of such refund or overpayment (including, for the avoidance of doubt, any interest or other amounts received with respect to such refund or overpayment), net of any additional taxes that MCK incurs as a result of the receipt of such refund or such overpayment. For the avoidance of doubt, any applicable gross receipts-based or income-based taxes in respect of the Service Fees shall be borne by MCK.

2.4 Late Payments . MCK may assess a late payment fee on any invoiced amount that is not paid when due (except to the extent subject to a Dispute), at the lesser of (i) a rate of 1.5% per month and (ii) the highest rate then permitted by Applicable Law, from and after the date on which the invoice first became overdue.

3.1 Ownership . This Agreement and the performance of this Agreement will not affect the ownership of any Intellectual Property Right allocated in any other Transaction Document. Neither party will gain, by virtue of this Agreement, any rights of ownership of any Intellectual Property Right owned by the other party without the mutual written agreement of the parties. Subject to the foregoing, (a) to the extent any financial and accounting data is newly created on behalf of NewCo pursuant to a Service provided hereunder, such data shall be owned by NewCo and (b) to the extent any Services involve custom engineering or software developed exclusively for the use of NewCo, NewCo shall hereby be assigned ownership in the Intellectual Property Rights for such work product.

3.2 License . During the Transition Services Period (defined in Section 8.1), NewCo hereby grants to MCK a worldwide, nonexclusive, royalty-free, fully paid-up, non-transferable, non-sublicensable (except to MCK’s Affiliates and MCK’s and its Affiliates’ subcontractors performing hereunder on MCK’s behalf) license under its Intellectual Property Rights to the extent reasonably necessary to perform the Services for NewCo hereunder. Except as otherwise expressly provided in the Service Schedule, nothing in this Agreement will be deemed to grant or extend, directly or by implication, estoppel or otherwise, any right or license with respect to any Intellectual Property Rights of MCK or any third-party.

4.1 Definition . “ Confidential Information ” means information or material disclosed or made available by one party (“ Discloser ”) to the other party (“ Recipient ”) in connection with the performance of, or matters related to, this Agreement, including information or material about the Discloser’s or any third-party’s business, products, technologies, strategies, advertisers, financial information, operations or activities, whether verbally, in writing or otherwise, that has been designated as confidential or that, given the nature of the information or material and/or the circumstances surrounding its disclosure, should reasonably be considered by the Recipient to be confidential information of the Discloser.

The parties agree that, for purposes of the foregoing, reasonable consultation and cooperation will include the acceptance and incorporation of any reasonable requests or comments made by Discloser in connection with any submission of such materials and any responses or correspondence with any applicable governmental or regulatory authority or other third-party in connection therewith.

4.3 Length of Obligation . Recipient’s obligation under Section 4.2 with respect to any Confidential Information will continue in perpetuity subject to the terms and conditions set forth therein.

NewCo will comply with all policies and procedures of MCK in connection with any access to or use of any MCK Systems. NewCo will not (i) render any MCK Systems unusable or inoperable, or otherwise interfere with or impede MCK’s or its Affiliates’ use of or access to any MCK Systems; (ii) take possession of or exclude MCK or its Affiliates from any MCK Systems; or (iii) otherwise impede or interfere with MCK’s or its Affiliates’, or their employees’, customers’ or end users’, businesses. NewCo will not access or use or attempt to access or use any MCK Systems, or any information or materials residing on any MCK Systems, except to the extent expressly authorized in writing by MCK or expressly required to receive the Services described in the Service Schedule. Without limitation of the foregoing, NewCo will cease all access to and use of the MCK Systems and any information or materials residing on any MCK Systems immediately upon expiration or termination of the Services described in the Service Schedule.

(b) Without limitation of this Article 4, Confidential Information of NewCo includes all employee, customer and user data, software (including source and object code), technology, documentation, and other information and materials residing on NewCo’s networks and systems to which MCK may have access in connection with providing the Services described in the Service Schedule (the “ NewCo Systems ”).

(a) NewCo hereby agrees to indemnify and hold harmless MCK and any other third-party providers of Services and their respective directors, officers, employees, Affiliates, agents and representatives and their successors and assigns (the “ MCK Indemnitees ”) from and against any and all third-party claims brought against the MCK Indemnitees for damages, losses or expenses (including reasonable attorneys’ fees and expenses and any other expenses reasonably incurred in connection with investigating, prosecuting or defending any claim, action, proceeding or investigation), other than taxes (“ Damages ”) asserted against or incurred by any of the MCK Indemnitees as a result or arising out of the Services supplied by any of the MCK Indemnitees pursuant to this Agreement, but only to the extent such Damages result from or arise out of fraud, gross negligence or willful misconduct by any of the NewCo Indemnitees.

(b) MCK hereby agrees to indemnify and hold harmless NewCo and its directors, officers, employees, Affiliates, agents and representatives and their successors and assigns (the “ NewCo Indemnitees ”) from and against any and all third-party claims brought against the NewCo Indemnitees for Damages asserted against or incurred by any of the NewCo Indemnitees as a result or arising out of the Services supplied by any of the MCK Indemnitees pursuant to this Agreement, but only to the extent such Damages result from or arise out of fraud, gross negligence or willful misconduct by any of the MCK Indemnitees.

6.2 Exclusive Remedy. Without limitation to the termination rights under this Agreement, the indemnification provisions of this Section 6 shall be the exclusive remedy for money damages for third-party claims arising under this Agreement (it being understood that nothing in this Section 6.2 shall be construed as limiting the right of a party to make a claim for direct damages for a breach of this Agreement by the other party).

6.3 Indemnification Process . The indemnification process set forth in Section 8.04 of the Contribution Agreement will apply with respect to claims for indemnification from and against third-party claims under this Agreement mutatis mutandis , including with respect to control of the defense of such third-party claims. But, for avoidance of doubt, any such claim for indemnification under this Agreement will be subject to the terms of this Agreement (including with respect to any applicable limitation of liability) and not under the terms of the Contribution Agreement.

THE FOREGOING LIMITATION ON LIABILITY WILL NOT APPLY TO, AND WILL BE IN ADDITION TO, ANY FEES PAYABLE HEREUNDER. THE PARTIES EXPRESSLY ACKNOWLEDGE THAT, NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN OR IN THE CONTRIBUTION AGREEMENT OR THE OTHER TRANSACTION DOCUMENTS, NEITHER PARTY MAY BRING ANY CLAIM UNDER ANY PROVISION OF THE CONTRIBUTION AGREEMENT OR THE OTHER TRANSACTION DOCUMENTS (INCLUDING, WITHOUT LIMITATION, ARTICLE 8 OF THE CONTRIBUTION AGREEMENT (INDEMNIFICATION)) WITH RESPECT TO ANY CLAIM ALLEGING THAT MCK HAS BREACHED ANY TERM OF THIS AGREEMENT.

8.1 Term of this Agreement . Unless terminated sooner as set forth herein, this Agreement will commence on the Closing Date and will continue in effect until the earlier of (a) the day the service periods for all Services have expired or been terminated or (b) ten (10) days after the day NewCo has provided written notice to MCK that MCK’s provision of the Services is no longer required, unless a longer notice period is specified on the Service Schedule (such period, the “ Transition Services Period ”). At least thirty (30) days before the scheduled end of Service that has not been fully transitioned, NewCo may provide written notice to MCK that the term of the Service will need to be extended for an additional period during which the parties will complete the separation, migration and transition of the Service. Existing Service Fees for such Service will continue on a month-to-month basis for the extension period.

8.2 Termination of Service . Except as otherwise set forth on the Service Schedule, NewCo may, upon thirty (30) days’ written notice to MCK, terminate or reduce the quantity of a Service prior to the end date of the service period for such Service as set forth in the Service Schedule. In the event of such termination of a Service, MCK will not charge NewCo such

portion of the monthly Service Fees (or will refund to NewCo such portion of the monthly Service Fees, if pre-paid) for the terminated Service as is determined by a pro-rata per day calculation or other mutually accepted method for the days remaining in the then-current month after the effective date of the termination of the Service; provided, however, that NewCo shall be obligated to pay to MCK any portion of the monthly Service Fees in such then-current month to the extent that such Service Fees relate to non-cancellable or non-refundable costs incurred by MCK and its Affiliates in connection with providing the Services. Without limiting the foregoing, if MCK fails to provide a Service hereunder, or the quality of a Service is not in accordance with Section 1.2, then NewCo will provide MCK written notice thereof. MCK will then have fifteen (15) days to dispute or cure the defective Service. If MCK fails to dispute or cure the defective Service within fifteen (15) days after receipt of such written notice, then during the thirty (30) days thereafter, the parties shall use commercially reasonable efforts to agree upon a resolution to such defect. If the parties are unable to agree to a resolution during such thirty (30)-day period, then NewCo may exercise the rights and remedies provided herein with respect to such defective Service.

8.3 Termination by MCK . If NewCo fails to make in full any payment required under this Agreement (except if the payment is subject to a Dispute), and the failure to pay is not cured within fifteen (15) days of receiving written notice thereof from MCK, MCK may elect, at its sole discretion, to either terminate this Agreement or suspend the provision of any or all of the Services. In addition, in the event of a material breach by NewCo or its Affiliates of any of its other obligations under this Agreement, and failure by NewCo to remedy such breach in all material respects within ninety (90) days after receipt of written notice of the breach, MCK may terminate the Service(s) affected by such uncured breach or suspend its performance of such affected Service(s).

8.4 Termination by Either Party . In addition, either party may terminate this Agreement (and MCK may suspend its performance of any or all of the Services) by providing written notice to the other party in the event of the dissolution, termination of existence, liquidation, filing for bankruptcy or similar protection or insolvency of the other party.

8.5 Effect of Termination . Upon expiration or termination of this Agreement for any reason, MCK will no longer be obligated to provide the Services, and NewCo will no longer be obligated to pay for such Services, except with respect to any Service Fees and any other applicable fees and reimbursable expenses incurred up to the date of termination or expiration (all such fees, including any applicable late fees, will become immediately due and payable by NewCo to MCK upon the effective date of such termination). In the event of expiration or termination of this Agreement or any particular Service in accordance with the provisions of this Agreement (including the Service Schedule), MCK will not be liable to NewCo for any compensation, reimbursement or damages on account of any expenditures or investments made in connection with replacing any expired or terminated Services, or on account of loss of prospective profits or anticipated sales or any commitments made in connection with this Agreement or the anticipation of extended performance of this Agreement. Any termination or expiration of this Agreement shall not affect any right to recover for breaches or indemnification claims arising prior to the termination or expiration of this Agreement.

injunction or injunctions to prevent breaches or violations of the provisions of this Agreement or the Service Schedule and to enforce specifically this Agreement and the Service Schedule and the terms and provisions hereof and thereof in any claim instituted in any court specified in Section 9.6 in addition to any and all other rights and other remedies at law or in equity and all such rights and remedies will be cumulative.

(30) calendar days after the first date on which the TRA Party has received the applicable Schedule or amendment thereto unless the MCK Representative (i) within thirty (30) calendar days after receiving an applicable Schedule or amendment thereto, provides the Company with notice of a material objection to such Schedule (“ Objection Notice ”) made in good faith or (ii) provides a written waiver of such right of any Objection Notice within the period described in clause (i) above, in which case such Schedule or amendment thereto becomes binding on the date the waiver is received by the Company.

Within five (5) calendar days after a Tax Benefit Schedule delivered to a TRA Party becomes final in accordance with Section 2.04(a), the Company shall pay such TRA Party, for the Taxable Year to which such Tax Benefit Schedule relates, an aggregate amount equal to the Tax Benefit Payment Amount in respect of such TRA Party for such Taxable Year as determined pursuant to Section 3.01(b) (each, a “ Tax Benefit Payment ”).

For the avoidance of doubt, for Tax purposes, the Additional Amount shall not

be treated as interest but instead shall be treated as described in Section 2.03(b)(i)(A), unless otherwise required by law. The “ Net Tax Benefit ” for a Taxable Year shall be an amount equal to the excess, if any, of 85% of the Cumulative Net Realized Tax Benefit as of the end of such Taxable Year, over the total amount of payments previously made under Section 3.01(a) of this Agreement (excluding payments attributable to Additional Amounts); provided , for the avoidance of doubt, that no TRA Party shall be required to return any portion of any previously made Tax Benefit Payment.

Notwithstanding anything to the contrary in this Agreement, (i) after any lump-sum payment under Article 4 of this Agreement in respect of present or future Tax attributes subject to this Agreement, the Tax Benefit Payment Amount, Net Tax Benefit and components thereof shall be calculated without taking into account any such attributes with respect to which such a lump sum payment has been made or any such lump-sum payment. Notwithstanding the foregoing, for each Taxable Year ending on or after the date of a Change of Control, all Tax Benefit Payments shall be calculated by utilizing Valuation Assumptions (a) and (c), substituting in each case the terms “the closing date of a Change of Control” for an “Early Termination Date.”

Section 3.02. No Duplicative Payments . It is intended that the provisions of this Agreement will not result in duplicative payment of any amount (including interest) required under this Agreement. The provisions of this Agreement shall be construed in the appropriate manner to ensure such intentions are realized.

(b) After taking into account Section 3.03(a), if for any reason the Company does not fully satisfy its payment obligations to make all Tax Benefit Payments due under this Agreement in respect of a particular Taxable Year, then the Company and the TRA Parties agree that (i) the Company shall pay the same proportion of each Tax Benefit Payment due to each Person due a payment under this Agreement in respect of such Taxable Year, without favoring one obligation over the other, and (ii) no Tax Benefit Payment shall be made in respect of any Taxable Year until all Tax Benefit Payments in respect of prior Taxable Years have been made in full.

(c) To the extent the Company makes a payment to a TRA Party in respect of a particular Taxable Year under Section 3.01(a) of this Agreement (taking into account Section 3.03(a) and (b), but excluding payments attributable to Additional Amounts) in an amount in excess of the amount of such payment that should have been made to such TRA Party in respect

of such Taxable Year, then (i) such TRA Party shall not receive further payments under Section 3.01(a) until such TRA Party has foregone an amount of payments equal to such excess and (ii) the Company shall pay the amount of such TRA Party’s foregone payments to the other TRA Parties in a manner such that each of the other TRA Parties, to the maximum extent possible, shall have received aggregate payments under Section 3.01(a) of this Agreement (excluding payments attributable to Additional Amounts) in the amount it would have received if there had been no excess payment to such TRA Party.

(d) Notwithstanding anything in Section 3.01 to the contrary, during any Taxable Period in which Change is a member of the Echo Group (an “ Actual Consolidation Period ”), to the extent that the aggregate tax benefit of the Echo Group resulting from (x) the Transferred Basis, the Basis Adjustments or Imputed Interest and (y) Tax Assets or Payment Deductions (as defined in the Change TRA), is limited in a particular Taxable Year because the Echo Group does not have sufficient taxable income, the limitation on the tax benefit for the Echo Group shall be allocated among this Agreement and the Change TRA (and among all parties eligible for payments under each) in proportion to the respective amounts of Tax Benefit Payments (as defined in this Agreement and the Change TRA) that would have been determined under the this Agreement and the Change TRA (and allocated among such parties) if the Echo Group had sufficient taxable income so that there were no such limitation.

(e) Notwithstanding anything in Section 3.01 to the contrary, during any taxable period in which Change is not a member of the Echo Group (a “ Hypothetical Consolidation Period ”), if the amount of the Tax Benefit Payment (as defined in this Agreement and the Change TRA) that would have been determined either under this Agreement or the Change TRA, as the case may be, would have been larger if such taxable period were an Actual Consolidation Period (as determined after the application of Section 3.03(d)), then the Tax Benefit Payments to be made under this Agreement and the Change TRA shall be determined by (i) the Echo Group and Change determining the Tax Benefit Payments (as defined in this Agreement and the Change TRA) that would have been payable if Change were a member of the Echo Group for such Hypothetical Consolidation Period and (ii) then applying Section 3.03(d) in respect of such Tax Benefit Payments such that the Echo Group and Change are not required to pay, collectively, an amount in excess of the amount they would pay, collectively, absent this Section 3.03(e).

(f) If for any reason the Company does not fully satisfy its payment obligations to make all Tax Benefit Payments due under the Tax Receivable Agreements in respect of a particular Taxable Year, (i) Change and the Company, respectively, shall pay the same proportion of each Tax Benefit Payment due under each of this Agreement and the Change TRA in respect of such Taxable Year, without favoring one obligation over the other, and (ii) no Tax Benefit Payment shall be made in respect of any Taxable Year under either this Agreement or the Change TRA until all Tax Benefit Payments in respect of prior Taxable Years have been made in full under both this Agreement and the Change TRA.

(g) To the extent the Company or Change makes a payment to a TRA Party under this Agreement or to the Change Shareholders (as defined in the Change TRA) under the Change TRA, respectively, in an amount in excess of the amount of such payment that should have been made to such Person (an “ Overpaid Party ”) in respect of such Taxable Year, then (i) the Overpaid Party shall not receive further payments under this Agreement or the Change TRA, as

applicable, until the Overpaid Party has foregone an amount of payments equal to such excess and ( ii ) the Company or Change, as applicable, shall cause the amount of the Overpaid Party’s foregone payments to be paid to the other Person (the “ Underpaid Party ”), to the maximum extent possible, until the Underpaid Party shall have received aggregate payments under this Agreement in the amount it would have received if there had been no excess payment to the Overpaid Party.

(a) If the Company chooses to exercise its right of early termination under Section 4.01 above, other than in connection with a Change of Control, the Company shall deliver to each TRA Party notice of such intention to exercise such right (“ Early Termination Notice ”) and a schedule (the “ Early Termination Schedule ”) specifying the Company’s intention to exercise such right and showing in reasonable detail the calculation of the Early Termination Payment due for each TRA Party. Each Early Termination Schedule shall become final and binding on all parties thirty (30) calendar days after the first date on which the TRA Party has received such Schedule or amendment thereto unless the MCK Representative (a) within thirty (30) calendar days after receiving the Early Termination Schedule, provides the Company with notice of a material objection to such Schedule made in

good faith (“ Material Objection Notice ”) or (b) provides a written waiver of such right of a Material Objection Notice within the period described in clause (a) above, in which case such Schedule becomes binding on the date the waiver is received by the Company (such thirty (30) calendar day date as modified, if at all by clauses (a) or (b), the “ Early Termination Effective Date ”).

The consideration deemed to be received by such Person shall be equal to the gross fair market value of the contributed asset. For purposes of this Section 7.13, a transfer of an interest in an entity treated as a partnership or disregarded entity for U.S. federal income tax purposes shall be treated as a transfer of the transferor’s share of each of the assets and liabilities of that entity allocated to such transferor.

Notwithstanding anything to the contrary herein, each TRA Party and each of their assignees (and each employee, representative or other agent of the TRA Party or its assignees, as applicable) may disclose to any and all Persons, without limitation of any kind, the tax treatment and tax structure of the Company and its Affiliates, and any of their transactions, and all materials of any kind (including opinions or other tax analyses) that are provided to the TRA Party relating to such tax treatment and tax structure.

(b) If a TRA Party or an assignee commits a breach, or threatens to commit a breach, of any of the provisions of this Section 7.13, the Company shall have the right and remedy to

have the provisions of this Section 7.13 specifically enforced by injunctive relief or otherwise by any court of competent jurisdiction without the need to post any bond or other security, it being acknowledged and agreed that any such breach or threatened breach shall cause irreparable injury to the Company or any of its Affiliates or the TRA Parties and that money damages alone shall not provide an adequate remedy to such Persons.

Whether to effect or consummate a Transfer of Echo Shares pursuant to this Section 4.2 is in the sole and absolute discretion of Echo.

(a) Prior to a Qualified IPO, Echo and Blackstone shall take all Necessary Action to provide written notice to H&F of any direct Transfer (the “ Proposed Transfer ”) by Blackstone of any or all of its Echo Shares and/or Units directly owned by Blackstone (other than any Transfers (1) to Permitted Transferees or (2) made in accordance with Section 4.2 ) to any Person (such Person, the “ Proposed Transferee ”), including any Transfer in a ROFO Sale pursuant to the LLC Agreement, and at H&F’s written election in accordance with this Section 4.3 , H&F shall have the right to Transfer H&F’s Pro Rata Portion of Echo Shares and/or Units directly owned by H&F to the Proposed Transferee on the same terms and conditions as the corresponding portion of Units and/or Echo Shares proposed to be Transferred by Blackstone.

(b) Blackstone shall promptly give written notice (a “ Tag-Along Notice ”) to H&F of a Proposed Transfer, setting forth (i) the number of Units and/or Echo Shares proposed to be Transferred, (ii) in the event that Blackstone directly Transfers Units, the number of Echo Shares that represent such Units (calculated in accordance with the Echo Ratio), (iii) the maximum number of Echo Shares and/or Units the Proposed Transferee is willing to purchase (and the corresponding number of Echo Shares to be Transferred in respect of any such Units (calculated in accordance with the Echo Ratio)), (iv) the proposed per share purchase price (or amount) and form of consideration and (v) all other material terms and conditions of the Proposed Transfer, including the form of the proposed agreement, if any, and a firm offer by the Proposed Transferee to purchase the Echo Shares and/or Units from H&F in accordance with this Section 4.3 . Blackstone shall not structure the terms of any Proposed Transfer in a manner intended to unreasonably limit the ability of H&F to participate in the Proposed Transfer. H&F shall have a period of fifteen (15) Business Days from the date of receipt of the Tag-Along Notice within which to elect to sell up to its Pro Rata Portion of Echo Shares and/or Units directly owned by H&F in connection with such Proposed Transfer. H&F may exercise such right by delivery of an irrevocable written notice to Blackstone specifying the portion of its Pro Rata Portion of Echo Shares and/or Units it desires to include in the Proposed Transfer. If the Proposed Transferee fails to purchase all Echo Shares and/or Units proposed to be Transferred by Blackstone and H&F, then the number of Echo Shares and/or Units Blackstone and H&F are permitted to sell in such Tag-Along Transfer shall, subject to clause (z) of Section 4.3(c) hereof (in which event H&F shall be entitled to sell one hundred percent (100%) of its Echo Shares and Units), be reduced pro rata based on the relative number of Echo Shares and/or Units proposed to be included in the Proposed Transfer by Blackstone and H&F and, for the avoidance of doubt, Blackstone may not sell any Echo Shares and/or Units in the Proposed Transfer unless H&F is entitled to sell its Pro Rata Portion (or one hundred percent (100%) in the case of clause (y) of Section 4.3(c) hereof) of the Echo Shares and/or Units Transferred to the Proposed Transferee. Blackstone shall have a period of ninety (90) days following the expiration of the fifteen (15) Business Day period, to sell such Echo Shares and/or Units to the Proposed Transferee, on the terms and conditions specified in the Tag-Along Notice which, for the avoidance of doubt, shall be no more favorable to Blackstone than those set forth in the Tag-Along Notice. If Blackstone fails to sell such Echo Shares and/or Units to the Proposed Transferee within such ninety (90) days following the expiration of the fifteen (15) Business Day period from the date of receipt of the Tag-Along Notice, Blackstone shall not thereafter sell any Echo Shares or Units to the Proposed Transferee or any Person without first offering the same to H&F in the manner provided in this Section 4.3 .

(c) H&F shall agree (i) on a pro rata basis based on the number of Echo Shares and/or Units to be Transferred by Blackstone and H&F, to make the same representations, warranties and indemnities to the Proposed Transferee as made by Blackstone in connection with the Proposed Transfer, (ii) if required, to participate in any escrow or holdback arrangement relating to such Proposed Transfer pro rata based on the relative number of Echo Shares and/or Units to be Transferred by Blackstone and H&F and (iii) to the same terms and conditions to the Proposed Transfer as Blackstone agrees. All such representations, warranties and indemnities shall be made by H&F and Blackstone severally, and not jointly and severally, and, except with respect to individual representations, warranties and indemnities of H&F as to the unencumbered title to its Echo Shares and the power, authority and legal right to Transfer such Echo Shares and/or Units, any liability for breach of any such representations and warranties or under any indemnities shall be allocated among H&F and Blackstone pro rata based on the relative number of Echo Shares and/or Units to be Transferred by each of them. Notwithstanding anything herein to the contrary, (u) in no event shall the aggregate amount of liability for H&F and/or Blackstone exceed the U.S. dollar value of the net proceeds received by H&F or Blackstone, respectively,

from the Proposed Transferee, (v) in no event shall H&F be required to make any representations or warranties, or provide any indemnities as to, or to, any other Stockholder, (w) in no event shall H&F be required to agree or enter into any non-competition, non-solicitation or analogous or similar agreements or covenants that would bind H&F or its Affiliates or portfolio companies without H&F’s prior written consent, (x) any deferred consideration or indemnification payments made by the Proposed Transferee relating to such Proposed Transfer shall be allocated among H&F and Blackstone pro rata based on the relative number of Echo Shares and/or Units to be Transferred by each of them, (y) if the Proposed Transfer would result in a Company Sale or would result in H&F beneficially owning less than three percent (3%) of the outstanding Units, then H&F shall have the right to sell up to one hundred percent (100%) of its Echo Shares and Units directly owned by H&F and (z) to the extent that the consideration in such Proposed Transfer does not consist entirely of cash and/or Marketable Securities, H&F shall have the right to elect to receive an amount of cash equal to the Fair Market Value of H&F’s portion of any non-cash consideration in lieu of such non-cash consideration; provided that H&F shall only have the right set forth in this clause (z) in the event that H&F is entitled to Transfer up to one hundred percent (100%) of its Echo Shares and Units directly owned by H&F in the applicable Proposed Transfer. In determining “Fair Market Value” for purposes of this Section 4.3 , if applicable, Blackstone will deliver to H&F its proposed valuation of the consideration in the applicable Proposed Transfer. In the event that Blackstone and H&F are unable to reach an agreement on the Fair Market Value of such consideration within five (5) Business Days following the delivery of Blackstone’s proposed valuation, H&F and Blackstone shall each select one (1) nationally recognized investment banking or valuation firm for the purpose of determining the proposed Fair Market Value for such consideration, and the two firms so selected shall nominate a third such firm, and such third firm shall serve as the firm for purposes of this Section 4.2 and shall promptly (and in any event, within five (5) Business Days) be engaged (at Echo’s expense) by Echo. Such firm shall be instructed by Echo to provide its written determination to each of Blackstone and H&F within five (5) Business Days of its engagement. Such investment banking or valuation firm’s determination shall, absent fraud or manifest error, final conclusive and binding upon Echo, Blackstone and H&F.

(d) Concurrently with the consummation of the Proposed Transfer, Blackstone shall (i) notify H&F thereof, (ii) remit on the same day on which such Proposed Transfer is consummated to H&F the total consideration for the Echo Shares and/or Units that H&F Transferred pursuant thereto by wire transfer of immediately available funds and (iii) promptly after the consummation of such Proposed Transfer, furnish such other evidence of the completion and the date of completion of such Proposed Transfer and the terms thereof as may be reasonably requested by H&F. The Proposed Transferee in such Proposed Transfer must become a party to this Agreement if it is not already a party.

(e) All reasonable costs and expenses incurred in connection with any Proposed Transfer that is consummated, including all attorneys fees and charges, all accounting fees and charges and all finders, brokerage or investment banking fees, charges or commissions, shall be allocated between Blackstone and H&F pro rata based on the relative number of Echo Shares to be Transferred by each of them.

(f) If a Stockholder Transfers any Echo Shares or Units directly owned by such Stockholder to any of its Affiliates, such Affiliates shall be bound by the provisions of this Section 4.3 . Each Stockholder may assign its tag-along rights (in whole or in part) under the terms of this Section 4.3 to any of its Affiliates that is a Stockholder. Blackstone agrees that it will not Transfer any Echo Shares or Units directly owned by Blackstone (other than any Transfers (i) to Permitted Transferees or (ii) made in compliance with Section 4.2 ) except in compliance with this Section 4.3 . For the avoidance of doubt, this Section 4.3 shall not apply to direct Transfers of Units by the Company.

(a) In the event of a purported Transfer by a Stockholder of any Echo Shares in violation of the provisions of this Agreement, such purported Transfer will be void and of no effect, and Echo will not give effect to such Transfer. Any Transfer of Echo Shares, which Transfer is otherwise in compliance herewith, shall be permitted hereunder only if the transferee of such Echo Shares agrees in writing that it shall, upon such

Transfer, assume with respect to such Echo Shares the transferor’s obligations under this Agreement and become a party to this Agreement for such purpose, and any other agreement or instrument executed and delivered by such transferor in respect of Echo Shares, including, the LLC Agreement, as applicable; provided , however , that (i) this Section 4.4 shall not apply to Transfers of Echo Shares to a Stockholder already bound by this Agreement (but such Transferred Echo Shares shall be subject to this Agreement), and (ii) this Section 4.4(a) shall not apply to (x) Transfers pursuant to a registered public offering or Rule 144A sale in accordance with, and subject to the terms and conditions of, this Agreement, the LLC Agreement and the Registration Rights Agreement, or (y) any Transfer to a Drag-Along Buyer in a Drag-Along Sale. If any Transfer is made under this Agreement to a Permitted Transferee, in the event such transferee ceases to be a Permitted Transferee of the transferor, then the transferee shall promptly Transfer such Echo Shares or other Equity Interests back to the transferor or to another Permitted Transferee of the transferor.

Prior to a Qualified IPO, Echo shall take all Necessary Action (x) to deliver to the Sponsors, promptly (and in any event within one (1) Business Day) after its receipt by Echo, any Issuance Notice from the Company under Section 3.07 of the LLC Agreement and (y) at any such Sponsor’s written election, to cause Echo to take all Necessary Action to exercise its rights under the terms of Section 3.07 of the LLC Agreement, as if such terms applied, mutatis mutandis , to this Agreement, in each case in proportion to each such Sponsor’s ownership in Echo as of such time of such notice (or, if less, in the amount elected by such Sponsor) as if such Sponsor owned Equity Interests directly in the Company. In furtherance of the foregoing, it is the intent of Echo and the Sponsors that each Sponsor shall be entitled to participate in the rights of Echo under Section 3.07 of the LLC Agreement as if such Sponsor were a direct holder of Equity Interests in the Company. If at any time under Section 3.07 of the LLC Agreement new Equity Interests in the Company are offered in connection with Echo’s rights under Section 3.07 of the LLC Agreement, Echo, subject to any limitations under applicable law, shall provide each Sponsor with a copy of all applicable notices received from the Company in connection with such offering, promptly (and in any event within one (1) Business Day) after its receipt by Echo, and shall procure that, to the maximum extent possible, each Sponsor is given the opportunity to make any applicable elections (subject to the timing requirements of the LLC Agreement and a reasonable amount of time for Echo to pass such elections on to the Company) as if such Sponsor were the direct holder of a number of Equity Interests in Echo equal to its indirect Equity Interests in the Company. To the extent any Sponsor elects to purchase Equity Interests in connection with Section 3.07 of the LLC Agreement, such Sponsor shall contribute the purchase price of such Equity Interests to Echo and Echo shall (i) use such contribution to purchase such Equity Interests and (ii) issue a number of Equity Interests of Echo to such Sponsor determined in accordance with the Echo Ratio such that, as a result of such issuance, such Sponsor shall be the beneficial and indirect owner of the new Equity Interests of the Company acquired by Echo.

(b) Echo Preemptive Rights . Prior to a Qualified IPO, if Echo proposes to issue any Equity Interests other than in accordance with Section 5.1(a) hereof (other than issuances of Equity Interests (i) to employees of Echo pursuant to employee benefit plans or arrangements approved by the Board of Directors (and upon the exercise of employee equity options granted pursuant to any such plans or arrangements) or (ii) pursuant to the conversion of any convertible Equity Interests) (a “ New Issuance ” and any such securities, “ Newly Issued Securities ”), Echo shall provide written notice to each of the Sponsors and Other Investors that are Affiliates of a Sponsor of such anticipated issuance no later than twenty (20) Business Days prior to the anticipated issuance date (the “ Preemptive Rights Notice ”). The Preemptive Rights Notice shall set forth the material terms and conditions of the New Issuance, including the name and address of the proposed Person to whom the Newly Issued Securities are proposed to be issued, the proposed purchase price for the Newly Issued Securities (on a per security and on an aggregate basis, including the maximum amount), a description of any non-cash consideration in sufficient detail to permit a valuation thereof, the anticipated issuance date, the proposed manner of disposition,

and the purpose of such New Issuance. Each of the Sponsors (including their Permitted Transferees) and Other Investors that are Affiliates of a Sponsor shall have the right to purchase up to its Pro Rata Portion of such Newly Issued Securities at the price and on the terms and conditions specified in the Preemptive Rights Notice by delivering an irrevocable written notice to Echo no later than ten (10) Business Days before the anticipated issuance date, setting forth the number of such Newly Issued Securities for which such right is exercised. Such notice shall also include the maximum number of Newly Issued Securities such Stockholder would be willing to purchase in the event any other Stockholder entitled to participate elects to purchase less than its Pro Rata Portion of such Newly Issued Securities. If any such Stockholder elects not to purchase its full Pro Rata Portion of such Newly Issued Securities, Echo shall allocate any remaining amount among those Stockholders (pro rata, but up to, in the case of each such Stockholder, the maximum number specified by such Stockholder pursuant to the immediately preceding sentence) who have indicated in their notice to Echo a desire to purchase Newly Issued Securities in excess of their respective Pro Rata Portions.

(c) In the event the Sponsors and Other Investors that are Affiliates of a Sponsor do not purchase all such Newly Issued Securities in accordance with the procedures set forth in Section 5.1(b) , Echo or its relevant Subsidiary, as applicable, shall have sixty (60) days after the expiration of the anticipated issuance date (subject to extension if necessary to permit the expiration or early termination of the HSR Waiting Period) to sell to other Persons the remaining Newly Issued Securities at the price and on the terms and conditions specified in the Preemptive Rights Notice. If Echo or its relevant Subsidiary, as applicable, fails to sell such Newly Issued Securities within such sixty (60) days of the anticipated issuance date provided in the Preemptive Rights Notice (subject to extension if necessary to permit the expiration or early termination of the HSR Waiting Period), Echo or its relevant Subsidiary, as applicable, shall not thereafter issue or sell such Newly Issued Securities without first offering the same to the Sponsors and Other Investors that are Affiliates of a Sponsor in the manner provided in Section 5.1(b) .

(d) In the event that any Stockholder purchases any equity securities other than new Echo Shares pursuant to this Section 5.1 , such Stockholder shall execute a stockholders agreement and a registration rights agreement with respect to such securities each with terms (including parties) that are equivalent, mutatis mutandis, to this Agreement and the Registration Rights Agreement, respectively; provided , that (i) such Stockholder shall execute such stockholders agreement in the same capacity ( i.e. , a “Sponsor” or “Other Investor”) as such Stockholder has entered into this Agreement, and (ii) such stockholders agreement shall terminate upon the same terms and conditions as provided herein and such registration rights agreement shall terminate upon the same terms and conditions as provided in the Registration Rights Agreement.

(e) Any Newly Issued Securities constituting shares of capital stock of Echo acquired by any existing holder of Echo Shares pursuant to this Article V shall be deemed for all purposes hereof to be Sponsor Shares, Other Investor Shares or Management Shares hereunder of like kind with Echo Shares then held by the acquiring holder.

(f) The election by a Sponsor or Other Investor not to exercise its preemptive rights under this Section 5.1 in any one instance shall not affect its right (other than in respect of a reduction in its Ownership Interest, if applicable) as to any future issuances of securities that shall, for the avoidance of doubt, be subject to this Section 5.1 . Any attempted Transfer of such securities by Echo or any Subsidiary of Echo without first giving the Sponsors and Other Investors that are Affiliates of a Sponsor the rights described in this Section 5.1 shall be void and of no force and effect.

(g) For the avoidance of doubt, MCK (and its Permitted Transferred or other Affiliates) shall not have any preemptive rights under this Article V .

Section 5.2 Post-Issuance Compliance . Notwithstanding the requirements of Section 5.1 , but subject in all cases to the other provisions of this Agreement, Echo may proceed with any New Issuance prior to having complied with the provisions of Section 5.1 ; provided that Echo will following consummation of such new Issuance promptly provide to each of the Sponsors and Other Investors that are Affiliates of a Sponsor who would

have received the Preemptive Rights Notice pursuant to Section 5.1 , but for this Section 5.2, notice of such New Issuance and the Participation Notice described in Section 5.1 ; and will: (a) offer to issue to such Stockholder such number of Equity Interests of the type issued in such New Issuance as may be requested by such Stockholder (not to exceed an amount equal to (i) the Pro Rata Portion that such Stockholder would have been entitled to pursuant to Section 5.1 , multiplied by the number of Newly Issued Securities included in the New Issuance plus (ii) a number of additional Equity Interests sufficient to permit such Stockholder to acquire, in total, the same percentage of the aggregate number of all Equity Interests included in the relevant New Issuances effected pursuant to this Section 5.2 as such Stockholder would have been entitled to acquire had Echo proceeded with the relevant New Issuances under Section 5.1 rather than pursuant to this Section 5.2 ) on the same economic terms and conditions with respect to such securities as the subscribers in the Issuance received; and (b) keep such offer open for a period of ten (10) Business Days, during which period, each such Stockholder may accept such offer by sending a written acceptance to Echo committing to purchase an amount of such securities (not in any event to exceed the Pro Rata Portion such Stockholder would have been entitled to pursuant to Section 5.1 , multiplied by the number of Newly Issued Securities included in such issuance).

Section 5.3 Expenses . All costs and expenses incurred by Echo or any of its Subsidiaries in connection with any proposed New Issuance (whether or not consummated), including all attorneys fees and charges, all accounting fees and charges and all finders, brokerage or investment banking fees, charges or commissions, shall be paid by Echo. In connection with such proposed New Issuance (whether or not consummated), Echo shall pay the fees and out-of-pocket expenses of a single law firm for all Sponsors and Other Investors that are Affiliates of a Sponsor who have elected to participate in the purchase of Newly Issued Securities (selected by the Sponsors purchasing Newly Issued Securities).

of a shelf registration statement pursuant to Rule 415 under the Securities Act if so requested and if Echo is then eligible to use such registration (any such demanded registration that is not an IPO Demand, a “ Demand Registration ”), by delivering a written request therefor to Echo that specifies the number of Registrable Securities held by such Holders to be registered and the intended method of distribution thereof (such a request, a “ Holder Demand ”). As promptly as practicable, but no later than two (2) Business Days after receipt of a Holder Demand, Echo shall give written notice (the “ Demand Exercise Notice ”) of the Holder Demand to the Company and all other Holders. Such Holders shall have the option, within five (5) Business Days after the receipt of the Demand Exercise Notice, to request, in writing, that Echo include in such registration any Registrable Securities held by such Holder (which request shall specify the maximum number of Registrable Securities intended to be disposed of by such Holder). If Echo is a WKSI on the date of the Holder Demand, then the Holder Demand may request registration of an unspecified amount of Registrable Securities to be sold by the unspecified Holders. If Echo is not a WKSI on the date of the Holder Demand, then the Holder Demand shall specify the aggregate amount of Registrable Securities to be registered. Echo shall provide to a Holder the information necessary to determine Echo’s status as a WKSI upon request. To the extent Echo is a WKSI at the time any Holder Demand is made to Echo, and such Holder Demand requests that Echo file an automatic shelf registration statement (as defined in Rule 415 under the Securities Act) (an “ automatic shelf registration statement ”) on Form S-3, Echo shall file an automatic shelf registration statement that covers those Registrable Securities which are requested to be registered or, if requested, an unspecified amount of Registrable Securities. Echo shall use its reasonable best efforts to remain a WKSI (and not become an ineligible issuer (as defined in Rule 415 under the Securities Act)) during the period during which such automatic shelf registration statement is required to remain effective. If the automatic shelf registration statement has been outstanding for at least three (3) years, at the end of the third year Echo shall upon request refile a new automatic shelf registration statement covering the Registrable Securities. If at any time when Echo is required to re-evaluate its WKSI status, Echo determines that it is not a WKSI, Echo shall use its reasonable best efforts to refile the shelf registration statement on Form S-3 and, if such form is not available, Form S-1, and keep such registration statement effective during the period during which such registration statement is required to be kept effective. Echo shall, as expeditiously as reasonably possible, file a registration statement (the “ Demand Registration Statement ”) with the SEC for the registration of the Registrable Securities which Echo has been requested by Holders to register pursuant to this Section 2.1 and to use its reasonable best efforts to cause the Demand Registration Statement to be promptly (and in any case within 60 days after filing such Demand Registration Statement) declared effective under the Securities Act. Echo shall use its reasonable best efforts to effect the registration of Registrable Securities for distribution in accordance with the intended method of distribution set forth in a written request delivered by the Majority Participating Holders or, in the case of a Shelf Registration Statement, any Holder.

(i) For the avoidance of doubt, (A) no Holder may exercise registration rights hereunder in connection with a Qualified IPO (including any Tag-Along Right), (B) during the First Echo Sale Window: (i) only the Blackstone Holders shall be permitted to request any Demand Registration pursuant to this Agreement and (ii) the Echo Shareholders that are not Blackstone Holders and the MCK Members shall both be permitted to exercise rights under Section 2.1(b)(ii), (C) during an MCK Exit Window, the Echo Shareholders shall not be permitted to request any Demand Registration pursuant to this Agreement and the Echo Shareholders shall be permitted to exercise rights under Section 2.1(b)(iii), and (D) during the Second Echo Sale Window: (i) only the Sponsor Holders shall be permitted to request any Demand Registration pursuant to this Agreement and the MCK Members and any Echo Shareholders that do not participate in such demand shall be permitted to exercise rights under Section 2.1(b)(iv).

(ii) During the First Echo Sale Window, the Blackstone Holders shall only be permitted to make a Holder Demand for one or more underwritten offerings and the Echo Shareholders that are not Blackstone Holders and the MCK Members (and their Permitted Transferees) (in each case, a “ Tagging Seller ”) shall have the right, but not the obligation (a “ Tag-Along Right ”), to require Echo to include in the Demand Registration up to an aggregate number of shares of Common Stock representing each Tagging Seller’s Tag-Along Portion (such shares, the “ Tag-Along Shares ”), subject to Section 2.1(h) and Section 2.1(k). For the purposes of this Agreement, subject to Section 2.1(k), “ Tag-Along Portion ” means, with respect to any Tagging Seller, a number of shares of Common Stock equal to (A) the number of Registrable Securities owned by such Tagging Seller at such time, multiplied by (B) a fraction, (1) the numerator of which is the number of shares of Common Stock proposed to be registered in the Demand Registration by the Blackstone Holders, and (2) the denominator of which is the aggregate number of shares of Registrable Securities held by all Blackstone Holders prior to giving effect to any Exchange associated with such Demand Registration or any sales of Registrable Securities pursuant to such Demand Registration.

(iii) During an Exercise Window that is within the MCK Exit Window, the MCK Members shall only be permitted to make a Holder Demand for one or more underwritten offerings and the Echo Shareholders (in this case, the “ Tagging Sellers ”) shall have the right, but not the obligation, to require Echo to include in the Demand Registration up to an aggregate number of shares of Common Stock representing each Tagging Seller’s Tag-Along Portion, subject to Section 2.1(h) and Section 2.1(k); provided , that the defined terms “ Tagging Seller ,” “ Tag-Along Right ” and “ Tag-Along Shares ” shall be used, as applicable, to refer to the Echo Shareholders and their Registrable Securities, mutatis mutandis . For the purposes of this Section 2.1(b)(iii), subject to Section 2.1(k), “ Tag-Along Portion ” means, with respect to any Tagging Seller, a number of shares of Common Stock equal to (A) the number of Registrable Securities owned by such Tagging Seller at such time, multiplied by (B) a

fraction, (1) the numerator of which is the number of shares of Common Stock proposed to be registered in the Demand Registration by the MCK Members, and (2) the denominator of which is the aggregate number of shares of Registrable Securities held by all MCK Members prior to giving effect to any Exchange associated with such Demand Registration or any sales of Registrable Securities pursuant to such Demand Registration.

(iv) In any Holder Demand not described in Section 2.1(b)(ii) or Section 2.1(b)(iii) above, any Holder that did not participate in such Holder Demand (and their Permitted Transferees) (in this case, the “ Tagging Sellers ”) shall have the right, but not the obligation, to require Echo to include in the Demand Registration such number of shares of Common Stock as each such Holder may request in writing, subject to Section 2.1(h) and Section 2.1(k).

(c) Registration Statement Form . Registrations under this Section 2.1 shall be on such appropriate form of the SEC (i) as shall be selected by Echo and as shall be reasonably acceptable to the Majority Participating Holders and (ii) as shall permit the disposition of such Registrable Securities in accordance with the intended method or methods of disposition specified in such Participating Holders’ requests for such registration, including, without limitation, a continuous or delayed basis offering pursuant to Rule 415 under the Securities Act. Echo agrees to include in any such registration statement all information which, in the opinion of counsel to Echo, is necessary or desirable to be included therein.

(e) Selection of Underwriters . The underwriters of each underwritten offering of the Registrable Securities pursuant to this Section 2.1 shall be selected by the Majority Participating Holders; provided , that, except in the case of a “block trade,” such selection is subject to the consent of Echo (which is not to be unreasonably withheld).

(f) Right to Withdraw; Option to Participate in Shelf Takedowns . Subject to Section 2.1(j), any Participating Holder shall have the right to withdraw its request for inclusion of Registrable Securities in any registration statement pursuant to this Section 2.1 at any time prior to the effective date of such registration statement by giving written notice to Echo of its request to withdraw. Upon receipt of notices from each of the Participating Holders to withdraw their request for inclusion of Registrable Securities in any registration statement, Echo shall cease all efforts to obtain effectiveness of the applicable registration statement. In the event that any Holder has requested inclusion of Registrable Securities in a shelf registration, the Holder shall have the right, but, subject to Section 2.1(j), not the obligation, to participate in any offering of Registrable Securities under such shelf registration.

(g) Limitations on Registration on Demand . Following the Restriction End Date, Echo shall not be required to have a registration statement declared effective pursuant to a Demand Registration until at least 90 days after the effective date of any other registration statement filed by Echo pursuant to a previous Demand Registration. The aggregate offering value of the Registrable Securities to be registered pursuant to any such registration shall be at least $100 million (determined as of the date the Holder Demand is made), unless the registration demand is for the balance of the Registrable Securities held by the applicable Holder making a Holder Demand and its Affiliates.

(h) Priority in Registrations on Demand . Whenever Echo effects a registration pursuant to this Section 2.1 in connection with an underwritten offering by Holders, no securities other than Registrable Securities held by Holders shall be included among the securities covered by such registration unless the Majority Participating Holders consent in writing to the inclusion therein of such other securities and the inclusion of such other securities does not reduce the amount of Registrable Securities that may be included in such offering by the Participating Holders, which consent may be subject to terms and conditions determined by the consenting Holders in their sole discretion. If any registration pursuant to a Holder Demand involves an underwritten offering and the managing underwriter(s) of such offering shall inform Echo in writing of its belief that the number of Registrable Securities requested to be included in such registration pursuant to this Section 2.1, when added to the number of any such other securities permitted to be offered in such registration, would materially adversely affect such offering, or if, in the case of an offering during the First Echo Sale Window, an MCK Exit Window or the Second Echo Sale Window, the Majority Participating Holders in their sole discretion shall determine that the inclusion of such additional securities would materially adversely affect such offering, then, subject to the last sentence of this Section 2.1(h), the Participating Holders shall be entitled to participate only on a pro rata basis based on the number of Registrable Securities held by each such Participating Holder; provided, that if such offering is conducted during the First Echo Sale Window, an MCK Exit Window (but only in respect of the first Demand Registration requested by any MCK Member during the MCK Exit Window) or the Second Echo Sale Window, then, subject to Section 2.1(k), the number of Registrable Securities included in such Demand Registration by the Tag-Along Sellers shall be reduced at the sole discretion of the Majority Participating Holders prior to any reduction in the number of Registrable Securities included in such Demand Registration by the Majority Participating Holders.

(i) Postponement . If the filing, initial effectiveness or continued use of a registration statement required to be prepared and filed by it pursuant to this Section 2.1 at any time would require Echo to make an Adverse Disclosure, Echo shall be entitled, pursuant to a Board Resolution, once in any twelve-month period, to postpone for a reasonable period of time (but not exceeding 90 days) (the “ Postponement Period ”) the filing, initial effectiveness or continued use of such registration statement; provided , that no such Postponement Period shall extend the length of any Exercise Window. In such event, Echo shall immediately give the Participating Holders written notice of such determination, containing a specific statement of the reasons for such postponement and an approximation of the anticipated delay, and, after receipt of such notice, such Participating Holders agree to suspend use of the applicable registration

statement until the end of the Postponement Period. Echo shall immediately notify such Participating Holders in writing upon the expiration of any Postponement Period, amend or supplement the registration statement (and the included prospectus), if necessary, so it does not contain any untrue statement or omission and furnish to the Participating Holders such numbers of copies of such registration statement as so amended or supplemented as the Participating Holders may reasonably request. “ Adverse Disclosure ” means public disclosure of material non-public information that, in the good faith judgment of Echo, upon advice of counsel and as authorized by a Board Resolution, would require premature disclosure of any material financing, material corporate reorganization or other material transaction, obligation, fact or event involving Echo or the Company, as the case may be.

(j) Shelf Takedowns . In the event that Echo files a shelf registration statement under Rule 415 of the Securities Act pursuant to a Holder Demand and such registration becomes effective (such registration statement, a “ Shelf Registration Statement ”), any Holder of Registrable Securities registered on such Shelf Registration Statement shall have the right at any time or from time to time to elect to sell Registrable Securities in an underwritten offering, including a “block trade” conducted as an underwritten offering, pursuant to such registration statement (“ Shelf Registrable Securities ”) or in any other manner contemplated by the “Plan of Distribution” in such registration statement. Any Holder making a Holder Demand may make such election by delivering to Echo a written request (a “ Shelf Underwriting Request ”) for such underwritten offering to Echo specifying the number of Shelf Registrable Securities that such Holder desires to sell pursuant to such underwritten offering (the “ Shelf Underwriting ”). As promptly as practicable, but no later than two (2) Business Days after receipt of a Shelf Underwriting Request (or, in the case of a “block trade,” such shorter period as is reasonably practicable), Echo shall give written notice (the “ Shelf Underwriting Notice ”) of such Shelf Underwriting Request to all Holders of Shelf Registrable Securities, and the Shelf Underwriting Notice shall offer each Holder the opportunity to include in the Shelf Underwriting that number of Registrable Securities as each such Holder may request in writing in accordance with this Section 2.1(j). Echo shall include in such Shelf Underwriting (x) the Shelf Registrable Securities of the Holders making the Shelf Underwriting Request and (y) the Shelf Registrable Securities of any other Holder of Shelf Registrable Securities which shall have made a written request to Echo for inclusion in such Shelf Underwriting (which request shall specify the maximum number of Shelf Registrable Securities intended to be disposed of by such Holder) (such persons, “ Potential Takedown Participants ”) within three (3) Business Days after the Shelf Underwriting Notice has been delivered (or, in the case of a “block trade,” one (1) Business Day). If such Shelf Underwriting is being conducted as a “block trade,” any Potential Takedown Participant’s request to participate in such Shelf Underwriting shall be binding on the Potential Takedown Participant; provided that each such Potential Takedown Participant that elects to participate may condition its participation on such Shelf Underwriting being completed within ten (10) Business Days and/or its acceptance at a price per share (after giving effect to any underwriters’ discounts or commissions) to such Potential Takedown Participant of not less than ninety two percent (92%) (or such lesser percentage specified by such Potential Takedown

Participant) of the closing price for the shares of Common Stock on their principal trading market on the Business Day immediately prior to such Potential Takedown Participant’s election to participate (the “ Participation Conditions ”). Echo shall, as expeditiously as possible, use its reasonable best efforts to facilitate such Shelf Underwriting. Once a Shelf Registration Statement has been declared effective, the Holders of Registrable Securities may request, and Echo shall be required to facilitate, an unlimited number of Shelf Underwritings with respect to such Shelf Registration Statement; provided , however , that Echo shall not be required to facilitate a Shelf Underwriting until at least 90 days after the later of the date of the underwriting agreement in any prior Shelf Underwriting effected pursuant to this Section 2.1(j) and the effective date of any previous Demand Registration Statement pursuant to this Section 2.1. Notwithstanding anything to the contrary in this Section 2.1(j), (A) each Shelf Underwriting must include, in the aggregate (based on the shares of Common Stock included in such Shelf Underwriting by all Holders participating in such Shelf Underwriting), shares of Common Stock having an aggregate market value of at least $100 million (determined as of the date the Shelf Underwriting Request is made), unless the Shelf Underwriting is of the balance of the Registrable Securities held by the applicable Holder making a Holder Demand and its Affiliates and (B) each Shelf Underwriting is subject to Section 2.1(k).

(k) H&F Priority Sale Right . Anything in this Agreement to the contrary notwithstanding, in any underwritten offering pursuant to this Section 2.1 or Section 2.2 in which the H&F Holders are participating and that is initiated prior to the two-year anniversary of the Restriction End Date (an “ H&F Priority Offering ”), the number of Registrable Securities that the Blackstone Holders, the H&F Holders and the other Holders shall be entitled to include in such offering (including any Shelf Underwriting) shall, subject to Section 2.1(h) or 2.2(c), as applicable (as modified by the immediately succeeding sentence), be determined as follows: (i) if the Blackstone Holders are the Holders making a Holder Demand, then (A) the Tag-Along Percentage of the H&F Holders will be that percentage that would result in the H&F Holders being able to sell in such offering a number of Registrable Securities equal to (x) the number of Registrable Securities being sold by the Blackstone Holders in such offering or (y) if the H&F Holders own Registrable Securities with an aggregate market value of less than $100 million (determined as of the date the relevant Demand Exercise Notice, Shelf Underwriting Request or Incidental Registration Notice, as applicable, is delivered), then all of the Registrable Securities owned by the H&F Holders and (B) the Tag-Along Percentage of each other Tagging Seller will equal the greater of (x) the Tag-Along Percentage of such Tagging Seller determined without giving effect to this Section 2.1(k) and (y) a number of shares of Common Stock equal to (A) the aggregate number of shares of Registrable Securities owned by such Tagging Seller at such time multiplied by (B) a fraction, (1) the numerator of which is the aggregate number of shares of Common Stock proposed to be included in such offering by the Blackstone Holders and the H&F Holders and (2) the denominator of which is the aggregate number of Registrable Securities owned by the Blackstone Holders and the H&F Holders at such time, (ii) if the H&F Holders are the Holders making a Holder Demand, then (A) the Tag-Along Percentage of the Blackstone Holders will be that percentage that would result in the

Blackstone Holders being able to sell in such offering a number of Registrable Securities equal to the number of Registrable Securities being sold by the H&F Holders in such offering and (B) the Tag-Along Percentage of each other Tagging Seller will equal a number of shares of Common Stock equal to (A) the aggregate number of shares of Registrable Securities owned by such Tagging Seller at such time multiplied by (B) a fraction, (1) the numerator of which is the aggregate number of shares of Common Stock proposed to be included in such offering by the H&F Holders and the Blackstone Holders and (2) the denominator of which is the aggregate number of Registrable Securities owned by the H&F Holders and the Blackstone Holders at such time and (iii) if the Holder making a Holder Demand is not an H&F Holder or a Blackstone Holder or the offering is pursuant to Section 2.2, then the number of Registrable Securities that the Blackstone Holders and the H&F Holders shall be entitled to include in such offering shall be aggregated for purposes of determining (A) the Tag-Along Portion for the Blackstone Holders and/or the H&F Holders, as applicable, and (B) for determining the number of Registrable Securities that may be sold by the Blackstone Holders and the H&F Holders under any circumstances when the proviso in Section 2.1(h) is applicable and (x) then allocated to the Blackstone Holders and the H&F Holders in accordance with their respective Allocation Percentages (as defined below) and (y) to the extent that the H&F Holders do not request the inclusion of all of the Registrable Securities they are entitled to include in such offering pursuant to clause (x), then the number of Registrable Securities the Blackstone Holders shall be entitled to include in such offering shall be increased by the amount that the H&F Holders could have included pursuant to clause (x) but chose not to, provided that under no circumstances will the Blackstone Holders be entitled to include pursuant to this clause (iii) a number of Registrable Securities that exceeds the number they could have included but for this Section 2.1(k). Anything in Section 2.1(h) or 2.2(c) to the contrary notwithstanding, in the event of any H&F Priority Offering in which the number of Registrable Securities offered by the Holders will be cut back pursuant to Section 2.1(h) or 2.2(c) then, (1) the aggregate amount of Registrable Securities that may be offered and sold by the Blackstone Holders and the H&F Holders for purposes of such Section shall be determined on an aggregate basis treating the Blackstone Holders as Participating Holders regardless of whether they are offering and selling any Registrable Securities in such offering and (2) to the extent that the aggregate amount that may be sold by the H&F Holders and the Blackstone Holders in accordance with clause (1) is less than the aggregate amount requested to be included by the H&F Holders and the Blackstone Holders, then the aggregate amount that may be sold in such offering as determined in accordance with clause (1) shall be allocated between the H&F Holders (in the aggregate) and the Blackstone Holders (in the aggregate) in accordance with their respective Allocation Percentages. The “ Allocation Percentages ” of (I) the H&F Holders shall equal 50%, provided that if the H&F Holders own Registrable Securities with an aggregate market value of less than $100 million (determined as of the date the relevant Demand Exercise Notice, Shelf Underwriting Request or Incidental Registration Notice, as applicable, is delivered), then the Allocation Percentage of the H&F Holders will equal the lesser of 100% and the percentage that results in the H&F Holders being able to sell in such offering all of their Registrable Securities and (II) the Allocation Percentage of the Blackstone Holders will equal 100% minus the H&F Allocation Percentage.

(a) Right to Include Registrable Securities . If Echo at any time following the commencement of the Second Echo Sale Window proposes to register any of its equity securities under the Securities Act by registration on Form S-1 or Form S-3, or any successor or similar form(s) (except registrations (i) pursuant to Section 2.1, (ii) solely for registration of equity securities in connection with an employee benefit plan or dividend reinvestment plan on Form S-8 or any successor form thereto or (iii) in connection with any acquisition or merger on Form S-4 or any successor form thereto), whether or not for sale for its own account, it will each such time give prompt written notice to each of the Holders of its intention to do so (an “ Incidental Registration Notice ”) and such notice shall offer the Holders of Registrable Securities the opportunity to register under such registration statement such number of Registrable Securities as each such Holder may request in writing. Upon the written request of any such Holders (which request shall specify the maximum number of Registrable Securities intended to be registered by such Holder), made as promptly as practicable and in any event within three (3) Business Days after the receipt of any such notice, Echo shall include in such registration under the Securities Act all Registrable Securities which Echo has been so requested to register by each Holder (subject to Section 2.2(c)); provided , however , that if, at any time after giving written notice of its intention to register any equity securities and prior to the effective date of the registration statement filed in connection with such registration, Echo shall determine pursuant to a Board Resolution not to register or to delay registration of such equity securities, the Company and Echo shall give written notice of such determination and its reasons therefor to the Holders and (i) in the case of a determination not to register, Echo shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but the Company shall not be relieved from any obligation to pay the Registration Expenses in connection therewith as provided for in Section 2.2(d)) and (ii) in the case of a determination to delay registering, shall be permitted to delay registering any Registrable Securities for the same period as the delay in registering such other securities and, in the case of each of (i) and (ii) directly above, without prejudice to the rights of the Holders to request that such registration be effected as a registration under Section 2.1. No registration effected under this Section 2.2 shall relieve Echo of its obligation to effect any registration upon request under Section 2.1.

(b) Right to Withdraw; Option to Participate in Shelf Takedowns . Any Holder shall have the right to withdraw its request for inclusion of Registrable Securities in any registration statement pursuant to this Section 2.2 at any time prior to the effective date of such registration statement by giving written notice to Echo of its request to withdraw. In the event that the Holder has requested inclusion of Registrable Securities in a shelf registration, the Holder shall have the right, but, subject to Section 2.1(j), not the obligation, to participate in any offering of Registrable Securities under such shelf registration.

(c) Priority in Incidental Registrations . If any registration pursuant to this Section 2.2 involves an underwritten offering and the managing underwriter(s) of such offering shall inform Echo in writing of its belief that the number of Registrable

Securities requested to be included in such registration or offering, when added to the number of other equity securities to be offered in such registration or offering, would materially adversely affect such offering, then Echo shall include in such registration or offering, to the extent of the number and type which Echo so advised can be sold in (or during the time of) such registration or offering without so materially adversely affecting such registration or offering (the “ Section 2.2 Sale Amount ”): (i) all of the securities proposed by Echo to be sold for its own account; and (ii) thereafter, to the extent the Section 2.2 Sale Amount is not exceeded, the Registrable Securities requested by the Participating Holders (provided that if all of the Registrable Securities requested by the Participating Holders may not be included, the Participating Holders shall, subject to Section 2.1(k), be entitled to participate on a pro rata basis based on the aggregate number of Registrable Securities held by the Participating Holders).

(d) Expenses . The Company shall pay, and shall be responsible for, all Registration Expenses in connection with any registration requested or offering effected pursuant to this Section 2.2 (other than underwriting discounts and commissions payable by Participating Holders with regard to shares of Common Stock sold by such Holders), including all expenses of the delivery of all documents required under Section 2.4(a)(vi).

(c) Each Participating Holder agrees that, upon receipt of any notice from Echo of the happening of any event of the kind described in Section 2.4(a)(vii)(C) or (E), each Participating Holder will, to the extent appropriate, discontinue its disposition of Registrable Securities pursuant to the registration statement relating to such Registrable Securities until, in the case of Section 2.4(a)(vii)(E), its receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.4(a)(vii)(E) and, if so directed by Echo, will deliver to Echo (at the Company’s expense) all copies, other than permanent file copies, then in its possession, of the prospectus relating to such Registrable Securities at the time of receipt of such notice.

(d) If any such registration statement or comparable statement under “blue sky” laws refers to any Holder by name or otherwise as the Holder of any securities of Echo, then such Holder shall have the right to require (i) the insertion therein of language, in form and substance satisfactory to such Holder and Echo, to the effect that the holding by such Holder of such securities is not to be construed as a recommendation by such Holder of the investment quality of Echo’s securities covered thereby and that such holding does not imply that such Holder will assist in meeting any future financial requirements of the Company or Echo, or (ii) in the event that such reference to such Holder by name or otherwise is not in the judgment of Echo, as advised by counsel, required by the Securities Act or any similar federal statute or any state “blue sky” or securities law then in force, the deletion of the reference to such Holder.

(a) Demanded Underwritten Offerings . If requested by the underwriters for any underwritten offering by the Participating Holders pursuant to a registration requested or offering effected under Section 2.1 (including without limitation an offering pursuant to Section 2.1(j)), Echo and the Company shall enter into a customary underwriting agreement with the managing underwriter(s) selected in accordance with Section 2.1(e) hereto. Such underwriting agreement shall be reasonably satisfactory in form and substance to such Participating Holders and shall contain such representations and warranties by, and such other agreements on the part of, Echo and the Company and such other terms as are generally prevailing in agreements of that type, including, without limitation, customary provisions relating to indemnification and contribution which are no less favorable to the recipient than those provided in Section 2.7 hereof. Each Participating Holder shall be a party to such underwriting agreement and may, at their option, require that any or all of the representations and warranties by, and the other agreements on the part of, Echo or the Company to and for the benefit of such underwriters shall also be made to and for the benefit of each Participating Holder and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement be conditions precedent to the obligations of each Participating Holder. No Participating Holder shall be required to make any representations or warranties to or agreements with Echo, the Company or the underwriters other than representations, warranties or agreements regarding such Participating Holder, its ownership of and title to the Registrable Securities, and its intended method of distribution; and any liability of any Participating Holder to any

underwriter or other Person under such underwriting agreement shall be limited to liability arising from information provided by such Participating Holder regarding itself to the managing underwriter of such offering and shall be limited to an amount equal to the proceeds (net of expenses and underwriting discounts and commissions) that it derives from such registration.

(b) Incidental Underwritten Offerings . In the case of a registration requested or offering effected pursuant to Section 2.2 hereof, if Echo shall have determined to enter into an underwriting agreement in connection therewith, all of the Registrable Securities to be included in such registration shall be subject to such underwriting agreement. The Participating Holders may, at their option, require that any or all of the representations and warranties by, and the other agreements on the part of, Echo or the Company to and for the benefit of such underwriters shall also be made to and for the benefit of the Participating Holders and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement be conditions precedent to the obligations of the Participating Holders. None of the Participating Holders shall be required to make any representations or warranties to or agreements with Echo, the Company or the underwriters other than representations, warranties or agreements regarding such Participating Holder, its ownership of and title to the Registrable Securities and its intended method of distribution; and any liability of any Participating Holder to any underwriter or other Person under such underwriting agreement shall be limited to liability arising from information provided by such Participating Holder regarding itself to the managing underwriter of such offering and shall be limited to an amount equal to the proceeds (net of expenses and underwriting discounts and commissions) that it derives from such registration.

(c) Participation in Underwritten Registrations . In the case of an underwritten registration pursuant to Section 2.1 or Section 2.2 hereof, as Echo may from time to time reasonably request in writing, Echo may require the Participating Holders (i) to furnish to Echo such information regarding such Participating Holders and the distribution of the Registrable Securities to enable Echo to comply with the requirements of applicable laws or regulations in connection with such registration and (ii) to complete and execute all customary questionnaires, powers of attorney, indemnitees, lock-up agreements, underwriting agreements and any other documents reasonably required under the terms of such underwriting arrangements.

(a) Indemnification by the Company .

such Company Indemnitee for any legal or any other fees or expenses incurred by it in connection with investigating or defending any such Loss, as incurred; provided that the Company shall not be liable to a Company Indemnitee to the extent that any such Loss arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such registration statements, any such preliminary prospectus, final prospectus, amendment or supplement, or document incorporated by reference therein, or any related free writing prospectus, in reliance upon and in conformity with information furnished by or to the Company or Echo by or on behalf of any Company Indemnitee.

(b) Indemnification by Participating Holders . As a condition to including any Registrable Securities in any registration statement or offering, the Company shall have received an undertaking reasonably satisfactory to them from each Participating Holder so including any Registrable Securities to, severally and not jointly, to the fullest extent permitted by law, indemnify and hold harmless (i) the Company Indemnitees and (ii) any underwriters of the Registrable Securities and each person who controls such underwriters (within the meaning of the Securities Act or the Exchange Act), with respect to any statement or alleged statement in or omission or alleged omission from such registration statement, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereto, or any related free writing prospectus, but only to the extent such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished by such Participating Holder to the Company or Echo that specifically states that it is for use in the preparation of such registration statement, preliminary prospectus, final prospectus, amendment or supplement, or any related free writing prospectus, and such Participating Holder shall reimburse such indemnified party for any reasonable legal or any other fees or expenses reasonably incurred by them in connection with investigating or defending any such Loss; provided , however , that the liability of such indemnifying party under this Section 2.7(b) shall be limited to the amount of proceeds (net of expenses and underwriting discounts and commissions) received by such indemnifying party in the offering giving rise to such liability. Each Participating Holder shall also, severally and not jointly, indemnify and hold harmless all other prospective sellers and Participating Holders, their respective Affiliates, direct and indirect officers, directors, successors, assigns, members, partners, shareholders, employees, advisors, representatives, and agents, and each Person who controls, directly or indirectly (within the meaning of the Securities Act or the Exchange Act), any such seller or Participating Holder to the same extent as provided above with respect to indemnification of the Company Indemnitees.

(c) Notices of Claims . Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in Section 2.7(a) or Section 2.7(b), such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party, give written notice to such indemnifying party of the commencement of such action or proceeding; provided , however , that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under Section 2.7(a) or Section 2.7(b), except to the extent that the indemnifying party is actually and materially prejudiced by such failure to give notice, and shall not relieve the indemnifying party from any liability which it may have to the indemnified party otherwise than under this Section 2.7.

(d) Defense of Claims . In case any such action or proceeding is brought against an indemnified party, except as provided for in the next sentence, the indemnifying party shall be entitled to participate therein and assume the defense thereof, jointly with any other indemnifying party, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by the indemnified party of such counsel, the indemnifying party shall not be liable to such indemnified party for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof, other than costs of investigation, and the indemnified party shall be entitled to participate in such defense at its own expense. If (i) the indemnifying party fails to notify the indemnified party in writing, within 15 days after the indemnified party has given notice of the action or proceeding, that the indemnifying party will indemnify the indemnified party from and against all Losses the indemnified party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the claim, (ii) the indemnifying party fails to provide the indemnified party with evidence acceptable to the indemnified party that the indemnifying party will have the financial resources to defend against the claim or proceeding and fulfill its indemnification obligations hereunder, (iii) the indemnifying party fails to defend diligently the action or proceeding within 10 days after receiving notice of such failure from such indemnified party; (iv) such indemnified party reasonably shall have concluded (upon advice of its counsel) that there may be one or more legal defenses available to such indemnified party or other indemnified parties which are different than those available to, or not available to, the indemnifying party; or (v) if such indemnified party reasonably shall have concluded (upon advice of its counsel) that, with respect to such claims, the indemnified party and the indemnifying party may have different, conflicting, or adverse legal positions or interests then, in any such case, the indemnified party shall have the right to assume or continue its own defense and the indemnifying party shall be liable for any fees and expenses therefor.

(e) Consent to Entry of Judgment and Settlements . No indemnifying party shall be liable for any settlement of any action or proceeding effected without its written consent, which consent shall not be unreasonably withheld; provided , that, in the case where the indemnifying party shall have failed to take any of the actions listed in clauses (i), (ii) or (iii) of the last sentence of Section 2.7(d), the indemnified party shall have the right to compromise or settle such action on behalf of and for the account, expense, and risk of the indemnifying party and the indemnifying party will remain responsible for any Losses the indemnified party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the action or proceeding to the fullest extent provided in this Section 2.7. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of the

indemnified party from all liability arising out of such action or claim, (B) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party and (C) does not require any action other than the payment of money by the indemnifying party.

(f) Contribution . If for any reason the indemnification provided for in Sections 2.7(a), (b) or (g) is unavailable to an indemnified party or insufficient in respect of any Losses referred to therein, then, in addition to the amount paid or payable under Sections 2.7(a), (b) or (g), the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such Loss (i) in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand, and the indemnified party on the other, with respect to the statements or omissions which resulted in such Loss, as well as any other relevant equitable considerations, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law or if the allocation provided in this clause (ii) provides a greater amount to the indemnified party than clause (i) above, in such proportion as shall be appropriate to reflect not only the relative fault but also the relative benefits received by the indemnifying party and the indemnified party from the offering of the securities covered by such registration statement as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 2.7(f) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the preceding sentence of this Section 2.7(f). No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The amount paid or payable by an indemnified party as a result of the Losses referred to in Sections 2.7(a), (b) or (g) shall be deemed to include, subject to the limitations set forth in Sections 2.7(a), (b) or (g), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding anything in this Section 2.7(f) to the contrary, no Participating Holder shall be required to contribute (1) any amount in excess of the proceeds (net of expenses and underwriting discounts and commissions) received by such Participating Holder from the sale of the Registrable Securities in the offering to which the Losses of the indemnified parties relate or (2) any amount in excess of the amount of indemnification which such Participating Holder would be required to pay pursuant to this Agreement if such indemnification provision was enforceable or applicable.

(g) Other Indemnification . Indemnification and contribution similar to that specified in the preceding subsections of this Section 2.7 (with appropriate modifications) shall be given by the Company and the Participating Holders with respect to any required registration or other qualification of securities under foreign or state or “blue sky” law or regulation. The indemnification agreements contained in this Section 2.7

shall be in addition to any other rights to indemnification or contribution which any indemnified party may have pursuant to law or contract and shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Indemnitee or other indemnified party and shall survive the transfer of any of the Registrable Securities by any such party.

(h) Indemnification Payments . The indemnification and contribution required by this Section 2.7 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or a Loss is incurred.

(i) The Company hereby acknowledges and agrees that a Company Indemnitee may have certain rights to indemnification, advancement of expenses and/or insurance provided by other sources. The Company hereby acknowledges and agrees (i) that it is the indemnitor of first resort ( i.e. , its obligations to a Company Indemnitee are primary and any obligation of such other sources to advance expenses or to provide indemnification for the same expenses or liabilities incurred by such Company Indemnitee are secondary) and (ii) that it shall be required to advance the full amount of expenses incurred by a Company Indemnitee and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement without regard to any rights a Company Indemnitee may have against such other sources.

cause its (and the Company’s, if different) officers and directors to enter into an agreement with the underwriters not to effect any public or private offer, sale, distribution or other disposition of equity interests, or any securities that are convertible or exchangeable or exercisable for equity interests, during the period referred to in clause (i) of this paragraph, including, without limitation, a sale pursuant to Rule 144 under the Securities Act on substantially the same terms as the Holders.

2.9. No Required Sale . Subject to Section 2.1(j), nothing in this Agreement shall be deemed to create an independent obligation on the part of any of the Holders to sell any Registrable Securities pursuant to any effective registration statement.

2.10. Rule 144; Rule 144A; Regulation S . Echo covenants that, at the Company’s expense, Echo will file or furnish, as applicable, the reports required to be filed by it under the Securities Act and the Exchange Act, and it will take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (i) Rules 144, 144A or Regulation S under the Securities Act or (ii) any similar rule or regulation hereafter adopted by the SEC.

(a) From and after the date of this Agreement until the Holders and their respective assigns shall no longer hold any Registrable Securities, without the prior written consent of the Blackstone Holders, the H&F Holders and the MCK Members, neither the Company nor Echo shall enter into an agreement that grants a holder or prospective holder of any securities of the Company or Echo demand or incidental registration rights that by their terms are not subordinate to the registration rights granted to the Holders in this Agreement. Notwithstanding the foregoing, if after the date of this Agreement the Company or Echo enters into any other agreement with respect to the registration of any of its equity securities, and the terms contained therein are more favorable to, or less restrictive on, the other party thereto than the terms and conditions contained in this Agreement (insofar as they are applicable) with respect to the Holders, then the terms of this Agreement shall immediately be deemed to have been amended without further action by the Company or Echo or the Holders so that the Holders shall be entitled to the benefit of any such more favorable or less restrictive terms or conditions.

(b) None of the Blackstone Holders, H&F Holders or MCK Members will offer or sell any Registrable Securities in any offering registered under the Securities Act except pursuant to the registration rights granted pursuant to this Agreement.

3.2. No Inconsistent Agreements . Neither the Company nor Echo will, on or after the date of this Agreement, enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in Section 2 or otherwise conflicts with the provisions of Section 2, other than any customary lock-up agreement with the underwriters in connection with any offering effected hereunder, pursuant to which neither the Company nor Echo shall agree to register for sale, and the Company and Echo shall agree not to sell or otherwise dispose of, Interests or any securities convertible into or exercisable or exchangeable for equity interest, for a specified period (not to exceed 90 days) following such offering. The Company and Echo warrants that the rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with any other agreements to which the Company and Echo is a party or by which it is bound. Neither the Company nor Echo has previously entered into any agreement with respect to its securities granting any registration rights to any Person.

4.1. Term . This Agreement shall terminate upon such time as there are no Registrable Securities, except for the provisions of Section 2.7 and Section 2.10 and all of this Section 4, which shall survive any such termination.

As promptly as practicable, the Change Shareholder Representatives and the Corporate Taxpayer shall agree on a replacement Closing Date Tax Asset Disclosure Letter to the extent necessary to reflect the actual amount of the items described in clauses (i), using a closing of the books methodology.

(a) Tax Benefit Schedule . Within 90 calendar days after the filing of the United States federal income Tax Return of the Corporate Taxpayer for any Taxable Year in which there is a Realized Tax Benefit or Realized Tax Detriment, the Corporate Taxpayer shall provide to the Change Shareholder Representatives a schedule showing, in reasonable detail, the calculation of the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year (a “ Tax Benefit Schedule ”).

(b) Applicable Principles . Subject to Section 3.3, the Realized Tax Benefit or Realized Tax Detriment for each Taxable Year is intended to measure the decrease or increase in the actual liability for Taxes of the Corporate Taxpayer and its Subsidiaries for such Taxable Year attributable to the Tax Assets and Payment Deductions determined using a “with and without” methodology.

The parties agree that all Tax Benefit Payments and other payments under this Agreement with respect to any shares of the Company redeemed in connection with the execution of this Agreement (to the extent permitted by law and other than amounts accounted for as interest under the Code) shall be treated as subsequent upward purchase price adjustments with respect to such redeemed shares that give rise to further deductions of Imputed Interest which such additional deductions in respect of Imputed Interest will be incorporated into the current year calculation and into future year calculations, as appropriate. If a deduction, carryover or carryback of any Tax item includes a portion that is attributable to the Tax Assets or Payment Deductions and another portion that is not, such portions shall be considered to be used in accordance with the “with and without” methodology. For the Taxable Year that includes the Closing Date, (i) any NOLs that would arise upon treating Closing Date as the last day of the Corporate Taxpayer’s Taxable Year shall be treated as Tax Assets and (ii) and Realized Tax Benefits or Realized Tax Detriments shall be determined for the period beginning the day after the Closing Date and ending on the last day of the Corporate Taxpayer’s Taxable Year.

(a) Procedure . Every time the Corporate Taxpayer delivers to the Change Shareholder Representatives an applicable Schedule under this Agreement, including any Amended Schedule delivered pursuant to Section 2.3(b), but excluding any Early Termination Schedule or amended Early Termination Schedule, the Corporate Taxpayer shall also (x) deliver to the Change Shareholder Representatives schedules, valuation reports and work papers, as determined by the Corporate Taxpayer or requested by the Change Shareholder Representatives, providing reasonable detail regarding the preparation of the Schedule and (y) allow the Change Shareholder Representatives reasonable access at no cost to the appropriate representatives at the Corporate Taxpayer, as determined by the Corporate Taxpayer or requested by the Change Shareholder Representatives, in connection with a review of such Schedule. Without limiting the application of the preceding sentence, each time the Corporate Taxpayer delivers to the Change Shareholder Representatives a Tax Benefit Schedule, in addition to the Tax Benefit Schedule duly completed, the Corporate Taxpayer shall deliver to the Change Shareholder Representatives the Corporate Taxpayer Return, the reasonably detailed calculation by the Corporate Taxpayer of the Hypothetical Tax Liability, the reasonably detailed calculation by the Corporate Taxpayer of the actual Tax liability, as well as any other work papers as determined by the Corporate Taxpayer or requested by the Change Shareholder Representatives. An applicable Schedule or amendment thereto shall become final and binding on all parties 30 calendar days from the first date on which the Change Shareholder Representatives have received the applicable Schedule or amendment thereto unless the Change Shareholder Representatives (i) within 30 calendar days after receiving an applicable Schedule or amendment thereto, provides the Corporate Taxpayer with notice of a material objection to such Schedule (“ Objection Notice ”) made in good faith or (ii) provides a written waiver of such right of any Objection Notice within the period described in clause (i) above, in which case such Schedule or amendment thereto becomes binding on the date the waiver is received by the Corporate Taxpayer. If the parties, for any reason, are unable to successfully resolve the issues raised in the Objection Notice within 30 calendar days after receipt by the Corporate Taxpayer of an Objection Notice, the Corporate Taxpayer and the Change Shareholder Representatives shall employ the reconciliation procedures as described in Section 7.9 of this Agreement (the “ Reconciliation Procedures ”).

(b) Amended Schedule . The applicable Schedule for any Taxable Year may be amended from time to time by the Corporate Taxpayer (i) in connection with a Determination affecting such Schedule, (ii) to correct inaccuracies in the Schedule identified as a result of the receipt of additional factual information relating to a Taxable Year after the date the Schedule was provided to the Change Shareholder Representatives, (iii) to comply with the Expert’s determination under the Reconciliation Procedures, (iv) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to a carryback or carryforward of a loss or other tax item to such Taxable Year, or (v) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to an amended Tax Return filed for such Taxable Year (any such Schedule, an “ Amended Schedule ”). The Corporate Taxpayer shall provide an Amended Schedule to the Change Shareholders within ninety (90) calendar days of the occurrence of an event referenced in clauses (i) through (v) of the preceding sentence. The Closing Date Tax Asset Disclosure Letter shall be appropriately

amended by the Change Shareholder Representatives and the Corporate Taxpayer to the extent that, as a result of a Determination the Corporate Taxpayer is required to calculate its Tax liability in a manner inconsistent with the Closing Date Tax Asset Disclosure Letter.

(a) Payments . Within five (5) calendar days after a Tax Benefit Schedule delivered to the Change Shareholder Representatives becomes final in accordance with Section 2.3(a), the Corporate Taxpayer shall pay to the Change Shareholders for such Taxable Year the Tax Benefit Payment determined pursuant to Section 3.1(b) in accordance with the percentages set forth on Schedule I . Each such Tax Benefit Payment shall be made by wire transfer of immediately available funds to the bank accounts previously designated by the Change Shareholder Representatives to the Corporate Taxpayer or as otherwise agreed by the Corporate Taxpayer and the Change Shareholder Representatives. For the avoidance of doubt, no Tax Benefit Payment shall be made in respect of estimated tax payments, including, without limitation, federal estimated income tax payments.

(b) A “ Tax Benefit Payment ” means an amount, not less than zero, equal to the sum of the Net Tax Benefit and the Additional Amount. The “ Net Tax Benefit ” for a Taxable Year shall be an amount equal to the excess, if any, of 85% of the Cumulative Net Realized Tax Benefit as of the end of such Taxable Year over the total amount of payments previously made under this Section 3.1 (excluding payments attributable to Additional Amounts and the Echo Connect Payment); provided , for the avoidance of doubt, that the Change Shareholders shall not be required to return any portion of any previously made Tax Benefit Payment. The “ Additional Amount” shall equal the additional amount on the Net Tax Benefit calculated at the Agreed Rate from the due date (without extensions) for filing the Corporate Taxpayer return with respect to Taxes for such Taxable Year until the Payment Date. Notwithstanding the foregoing, for each Taxable Year ending on or after the date of a Change of Control, all Tax Benefit Payments shall be calculated by utilizing Valuation Assumptions (1) and (3), substituting in each case the terms “the closing date of a Change of Control” for an “Early Termination Date.”

(c) The Tax Benefit Payment payable to the Change Shareholders with respect to the first Taxable Year of the Corporate Taxpayer that ends after the Closing Date shall be increased by the Echo Connect Payment. The “ Echo Connect Payment ” shall mean an amount equal to (i) the amount of Tax the Corporate Taxpayer and its Subsidiaries would have paid as a result of the Echo Connect Separation without taking into account the Transaction Tax Deductions or the Tax Assets over (ii) the actual amount of Tax paid in respect of the Echo Connect Separation, taking into account the use of the Transaction Tax Deductions and the Tax Assets that reduce the gain resulting from the Echo Connect Separation. The Tax Benefit Schedule for the first Taxable Year of the Corporate Taxpayer that ends after the Closing Date shall include in reasonable detail, the calculation of the Echo Connect Payment.

Section 3.2. No Duplicative Payments . It is intended that the provisions of this Agreement will not result in duplicative payment of any amount (including interest) required under this Agreement. The provisions of this Agreement shall be construed in the appropriate manner to ensure such intentions are realized.

(a) Notwithstanding anything in Section 3.1 to the contrary, during any taxable period in which Change is a member of the Echo Group (an “ Actual Consolidation Period ”), to the extent that the aggregate tax benefit of the Echo Group resulting from (x) the Transferred Basis, the Basis Adjustments or Imputed Interest (each as defined in the MCK TRA) and (y) the Tax Assets and the Payment Deductions is limited in a particular Taxable Year because the Echo Group does not have sufficient taxable income, the limitation on the tax benefit for the Echo Group shall be allocated among this Agreement and the MCK TRA (and among all parties eligible for payments under each) in proportion to the respective amounts of Tax Benefit Payments (as defined in this Agreement and the MCK TRA) that would have been determined under the this Agreement and the MCK TRA (and allocated among such parties) if the Echo Group had sufficient taxable income so that there were no such limitation.

(b) Notwithstanding anything in this Agreement to the contrary, during any taxable period in which Change is not a member of the Echo Group (a “ Hypothetical Consolidation Period ”), if the amount of the Tax Benefit Payment (as defined in this Agreement and the Change TRA) that would have been determined either under this Agreement or the Change TRA, as the case may be, would have been larger if such taxable period were an Actual Consolidation Period (as determined after the application of Section 3.3(a)), the Tax Benefit Payments to be made under this Agreement and the Change TRA shall be determined by (i) the Echo Group and Change determining the Tax Benefit Payments (as defined in this Agreement and the MCK TRA) that would have been payable if Change were a member of the Echo Group for such Hypothetical Consolidation Period and (ii) then applying Section 3.3(a) in respect of such Tax Benefit Payments such that the Echo Group and the Corporate Taxpayer are not required to pay, collectively, an amount in excess of the amount they would pay, collectively, absent this Section 3.3(b).

(c) If for any reason the Corporate Taxpayer does not fully satisfy its payment obligations to make all Tax Benefit Payments due under the Tax Receivable Agreements in respect of a particular Taxable Year, (i) the Corporate Taxpayer and the JV, respectively, shall pay the same proportion of each Tax Benefit Payment due under each of this Agreement and the MCK TRA in respect of such Taxable Year, without favoring one obligation over the other, and (ii) no Tax Benefit Payment shall be made in respect of any Taxable Year under either this Agreement or the MCK TRA until all Tax Benefit Payments in respect of prior Taxable Years have been made in full under both this Agreement and the MCK TRA.

(d) To the extent the Corporate Taxpayer or the JV makes a payment to a Change Shareholder under this Agreement or TRA Party (as defined in the MCK TRA) under the MCK TRA, respectively, in an amount in excess of the amount of such payment that should have been made to such Person (an “ Overpaid Party ”) in respect of such Taxable Year, then (i) the Overpaid Party shall not receive further payments under this Agreement or the MCK TRA, as applicable, until the Overpaid Party has foregone an amount of payments equal to such excess and (ii) the Corporate Taxpayer or the JV, as applicable, shall cause the amount of the Overpaid

Party’s foregone payments to be paid to the other Person(s) (the “ Underpaid Party ”), to the maximum extent possible, until the Underpaid Party shall have received aggregate payments under this Agreement in the amount it would have received if there had been no excess payment to the Overpaid Party.

(e) The parties hereto agree that the parties to the MCK TRA are expressly made third party beneficiaries of the provisions of this Section 3.3.

(a) The Corporate Taxpayer may terminate this Agreement with respect to all amounts payable to the Change Shareholders at any time by paying to the Change Shareholders the Early Termination Payment; provided , that this Agreement shall terminate pursuant to this Section 4.1(a) with respect to a Change Shareholder only upon the receipt by such Change Shareholder of its Early Termination Payment, and the Corporate Taxpayer shall deliver an Early Termination Notice only if the Corporate Taxpayer is able to make all required Early Termination Payments under this Agreement at the time required by Section 4.3; and provided , further , that the Corporate Taxpayer may withdraw any notice to execute its termination rights under this Section 4.1(a) prior to the time at which any Early Termination Payment has been paid. Upon payment of the Early Termination Payment by the Corporate Taxpayer, the Corporate Taxpayer shall not have any further payment obligations under this Agreement, other than for any (a) Tax Benefit Payment agreed to by the Corporate Taxpayer and the Change Shareholder Representatives as due and payable but unpaid as of the Early Termination Notice and (b) Tax Benefit Payment due for the Taxable Year ending with or including the date of the Early Termination Notice (except to the extent that the amount described in this clause (b) is included in the Early Termination Payment).

(b) In the event that a Senior Obligation of the Corporate Taxpayer, Echo or any of their Subsidiaries is accelerated (or deemed accelerated) in connection with an event of default (other than an event of default triggered upon a change in control) (“ Accelerated ” and such event, an “ Acceleration ”), then all obligations hereunder shall be Accelerated and such obligations shall (i) be calculated as if an Early Termination Notice had been delivered on the date of such acceleration and the Early Termination Payments shall be calculated (x) as if an Early Termination Notice had been delivered on the date of the Acceleration and (y) applying the Valuation Assumptions as if all tax attributes described therein are fully utilized in the year of such Acceleration, (ii) include any Tax Benefit Payments agreed to by the Change Shareholder Representatives and the Corporate Taxpayer as due and payable but unpaid as of the date of an Acceleration, and (iii) include any Tax Benefit Payment due for the Taxable Year ending with or including the date of an Acceleration; provided that procedures similar to the procedures of Section 4.2 shall apply with respect to the determination of the amount payable by the Corporate Taxpayer pursuant to this sentence.

(c) In the event that the Corporate Taxpayer breaches any of its material obligations under this Agreement, whether as a result of failure to make any payment when due, failure to

honor any other material obligation required hereunder or by operation of law as a result of the rejection of this Agreement in a case commenced under the Bankruptcy Code or otherwise, then all obligations hereunder shall be accelerated and such obligations shall (i) be calculated as if an Early Termination Notice had been delivered on the date of such breach and the Early Termination Payments shall be calculated as if an Early Termination Notice had been delivered on the date of the breach, (ii) include any Tax Benefit Payments agreed to by the Change Shareholder Representatives and the Corporate Taxpayer as due and payable but unpaid as of the date of a breach, and (iii) include any Tax Benefit Payment due for the Taxable Year ending with or including the date of a breach; provided that procedures similar to the procedures of Section 4.2 shall apply with respect to the determination of the amount payable by the Corporate Taxpayer pursuant to this sentence. Notwithstanding the foregoing, in the event that the Corporate Taxpayer breaches this Agreement, each Change Shareholder shall be entitled to elect to receive the amounts set forth in clauses (i), (ii) and (iii) above or to seek specific performance of the terms hereof.

(d) The parties agree that the failure to make any payment due pursuant to this Agreement within three months of the date such payment is due shall be deemed to be a breach of a material obligation under this Agreement for all purposes of this Agreement, and that it will not be considered to be a breach of a material obligation under this Agreement to make a payment due pursuant to this Agreement within three months of the date such payment is due. Notwithstanding anything in this Agreement to the contrary, it shall not be a breach of this Agreement if the Corporate Taxpayer fails to make any payment under this Agreement when due to the extent that the Corporate Taxpayer has insufficient funds to make such payment; provided that the interest provisions of Section 5.2 shall apply to such late payment (unless the Corporate Taxpayer does not have sufficient cash to make such payment as a result of limitations imposed by any credit agreement to which the Corporate Taxpayer or any of its Subsidiaries is a party if such limitations are no more onerous than the corresponding limitations imposed by the credit agreements to which the Company is a party at the Closing, in which case Section 5.2 shall apply, but the Default Rate shall be replaced by LIBOR plus 300 basis points).

(a) If the Corporate Taxpayer chooses to exercise its right of early termination under Section 4.1 above other than in connection with a Change of Control, the Corporate Taxpayer shall deliver to the Change Shareholder Representatives notice of such intention to exercise such right (“ Early Termination Notice ”) and a schedule (the “ Early Termination Schedule ”) specifying the Corporate Taxpayer’s intention to exercise such right and showing in reasonable detail the calculation of the Early Termination Payment for the Change Shareholder Representatives. The Early Termination Schedule shall become final and binding on all parties 30 calendar days from the first date on which the Change Shareholder Representatives has received such Schedule or amendment thereto unless the Change Shareholder Representatives (i) within 30 calendar days after receiving the Early Termination Schedule, provides the Corporate Taxpayer with notice of a material objection to such Schedule made in good faith (“ Material Objection Notice ”) or (ii) provides a written waiver of such right of a Material Objection Notice within the period described in clause (i) above, in which case such Schedule becomes binding on the date the waiver is received by the Corporate Taxpayer (such thirty (30) calendar day date as modified, if at all by clauses (i) or (ii), the “ Early Termination Effective Date ”). If the parties,

for any reason, are unable to successfully resolve the issues raised in such notice within 30 calendar days after receipt by the Corporate Taxpayer of the Material Objection Notice, the Corporate Taxpayer and the Change Shareholder Representatives shall employ the Reconciliation Procedures in which case such Schedule becomes binding ten (10) days after the conclusion of the Reconciliation Procedures.

Such payment shall be made by wire transfer of immediately available funds to a bank account or accounts designated by the Change Shareholder Representatives or as otherwise agreed by the Corporate Taxpayer and the Change Shareholder Representatives.

(b) “ Early Termination Payment ” shall equal the present value, discounted at the Early Termination Rate as of the Early Termination Effective Date, of all Tax Benefit Payments that would be required to be paid by the Corporate Taxpayer to the Change Shareholders beginning from the Early Termination Date and assuming that the Valuation Assumptions are applied, provided , that the Change of Control Termination Rate (instead of the Early Termination Rate) shall be used to determine the Early Termination Payment in the case of an early termination in connection with a Change of Control.

If the parties to the Dispute fail to agree on the selection of an arbitrator within ten (10) days of the receipt of the request for arbitration, the International Chamber of Commerce shall make the appointment. The arbitrator shall be a lawyer admitted to the practice of law in the State of New York and shall conduct the proceedings in the English language. Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings.

(b) Notwithstanding the provisions of paragraph (a), the Corporate Taxpayer may bring an action or special proceeding in any court of competent jurisdiction for the purpose of

compelling a party to arbitrate, seeking temporary or preliminary relief in aid of an arbitration hereunder, and/or enforcing an arbitration award and, for the purposes of this paragraph (b), the Change Shareholder Representatives (i) expressly consents to the application of paragraph (c) of this Section 7.8 to any such action or proceeding, (ii) agrees that proof shall not be required that monetary damages for breach of the provisions of this Agreement would be difficult to calculate and that remedies at law would be inadequate, and (iii) irrevocably appoints the Corporate Taxpayer as agent of the Change Shareholder Representatives for service of process in connection with any such action or proceeding and agrees that service of process upon such agent, who shall promptly advise the Change Shareholder Representatives of any such service of process, shall be deemed in every respect effective service of process upon the Change Shareholder Representatives in any such action or proceeding.

(c) (i) EACH PARTY HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF COURTS LOCATED IN NEW YORK, NEW YORK FOR THE PURPOSE OF ANY JUDICIAL PROCEEDING BROUGHT IN ACCORDANCE WITH THE PROVISIONS OF THIS SECTION 7.8, OR ANY JUDICIAL PROCEEDING ANCILLARY TO AN ARBITRATION OR CONTEMPLATED ARBITRATION ARISING OUT OF OR RELATING TO OR CONCERNING THIS AGREEMENT. Such ancillary judicial proceedings include any suit, action or proceeding to compel arbitration, to obtain temporary or preliminary judicial relief in aid of arbitration, or to confirm an arbitration award. The parties acknowledge that this paragraph (c) have a reasonable relation to this Agreement, and to the parties’ relationship with one another; and

(ii) The parties hereby waive, to the fullest extent permitted by applicable law, any objection which they now or hereafter may have to personal jurisdiction or to the laying of venue of any such ancillary suit, action or proceeding brought in any court referred to in the preceding paragraph of this Section 7.8 and such parties agree not to plead or claim the same.

Section 7.9. Reconciliation . In the event that the Corporate Taxpayer and the Change Shareholder Representatives are unable to resolve a disagreement with respect to the matters governed by Sections 2.3, 4.2 and 6.2 within the relevant period designated in this Agreement (“ Reconciliation Dispute ”), the Reconciliation Dispute shall be submitted for determination to a nationally recognized expert (the “ Expert ”) in the particular area of disagreement mutually acceptable to both parties. The Expert shall be a partner or principal in a nationally recognized accounting or law firm, and unless the Corporate Taxpayer and the Change Shareholder Representatives agree otherwise, the Expert shall not, and the firm that employs the Expert shall not, have any material relationship with the Corporate Taxpayer or the Change Shareholder Representatives or other actual or potential conflict of interest. If the parties are unable to agree on an Expert within fifteen (15) days of receipt by the respondent(s) of written notice of a Reconciliation Dispute, the Expert shall be appointed by the International Chamber of Commerce Centre for Expertise. The Expert shall resolve any matter relating to the Closing Date Tax Asset Disclosure Letter or an amendment thereto or the Early Termination Schedule or an amendment thereto within 30 calendar days and shall resolve any matter relating to a Tax Benefit Schedule or an amendment thereto within 15 calendar days or as soon thereafter as is reasonably practicable, in each case after the matter has been submitted to the Expert for resolution. Notwithstanding the preceding sentence, if the matter is not resolved before any payment that is the subject of a disagreement would be due (in the absence of such disagreement)

or any Tax Return reflecting the subject of a disagreement is due, the undisputed amount shall be paid on the date prescribed by this Agreement and such Tax Return may be filed as prepared by the Corporate Taxpayer, subject to adjustment or amendment upon resolution. The costs and expenses relating to the engagement of such Expert or amending any Tax Return shall be borne by the Corporate Taxpayer except as provided in the next sentence. The Corporate Taxpayer and the Change Shareholder Representatives shall bear their own costs and expenses of such proceeding, unless (i) the Expert adopts the Change Shareholder Representatives’ position, in which case the Corporate Taxpayer shall reimburse the Change Shareholder Representatives for any reasonable out-of-pocket costs and expenses in such proceeding, or (ii) the Expert adopts the Corporate Taxpayer’s position, in which case the Change Shareholder Representatives shall reimburse the Corporate Taxpayer for any reasonable out-of-pocket costs and expenses in such proceeding. Any dispute as to whether a dispute is a Reconciliation Dispute within the meaning of this Section 7.9 shall be decided by the Expert. The Expert shall finally determine any Reconciliation Dispute and the determinations of the Expert pursuant to this Section 7.9 shall be binding on the Corporate Taxpayer and the Change Shareholder Representatives and may be entered and enforced in any court having jurisdiction.

Section 7.10. Withholding . The Corporate Taxpayer shall be entitled to deduct and withhold from any payment payable pursuant to this Agreement such amounts as the Corporate Taxpayer is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign tax law, provided, however, that the Corporate Taxpayer shall notify the Change Shareholder Representatives (who shall notify the applicable Change Shareholder) in advance before applying any such withholding to allow such applicable payee a reasonable opportunity to provide any applicable certificates, forms or other certificates that would eliminate or reduce such withholding, and the Corporate Taxpayer will otherwise reasonably cooperate with the applicable payee to eliminate or reduce such withholding. To the extent that amounts are so withheld and paid over to the appropriate Taxing Authority by the Corporate Taxpayer, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Change Shareholders.

Section 7.11. Admission of the Corporate Taxpayer into a Consolidated Group; Transfers of Corporate Assets .

(a) If the Corporate Taxpayer is or becomes a member of an affiliated or consolidated group of corporations that files a consolidated income Tax Return pursuant to Sections 1501 et seq. of the Code or any corresponding provisions of state or local law, then: (i) the provisions of this Agreement shall be applied with respect to the group as a whole; and (ii) Tax Benefit Payments, Early Termination Payments and other applicable items hereunder shall be computed with reference to the consolidated taxable income of the group as a whole.

(b) If any entity that is obligated to make a Tax Benefit Payment or Early Termination Payment hereunder transfers one or more assets to a corporation (or a Person classified as a corporation for U.S. income tax purposes) with which such entity does not file a consolidated Tax Return pursuant to Section 1501 of the Code, such entity, for purposes of calculating the amount of any Tax Benefit Payment or Early Termination Payment (e.g., calculating the gross income of the entity and determining the Realized Tax Benefit of such entity) due hereunder, shall be treated as having disposed of such asset in a fully taxable

transaction on the date of such contribution. The consideration deemed to be received by such entity shall be equal to the fair market value of the contributed asset. For purposes of this Section 7.11, a transfer of a partnership interest shall be treated as a transfer of the transferring partner’s share of each of the assets and liabilities of that partnership.

Section 7.12. Confidentiality . The Change Shareholder Representatives and each of its assignees acknowledge and agree that the information of the Corporate Taxpayer is confidential and, except in the course of performing any duties as necessary for the Corporate Taxpayer and its Affiliates, as required by law or legal process or to enforce the terms of this Agreement, such person shall keep and retain in the strictest confidence and not disclose to any Person any confidential matters, acquired pursuant to this Agreement, of the Corporate Taxpayer and its Affiliates and successors learned by the Change Shareholder Representatives heretofore or hereafter. This Section 7.12 shall not apply to (i) any information that has been made publicly available by the Corporate Taxpayer or any of its Affiliates, becomes public knowledge (except as a result of an act of the Change Shareholder Representatives in violation of this Agreement) or is generally known to the business community, (ii) the disclosure of information to the extent necessary for the Change Shareholder Representatives to prepare and file its Tax Returns, to respond to any inquiries regarding the same from any taxing authority or to prosecute or defend any action, proceeding or audit by any taxing authority with respect to such returns, and (iii) any information a Change Shareholder discloses to a potential transferee pursuant to Section 7.7 under the terms of a confidential agreement the form of which is reasonably acceptable to the Corporate Taxpayer. Notwithstanding anything to the contrary herein, the Change Shareholder Representatives and each of their assignees (and each employee, representative or other agent of the Change Shareholder Representatives or its assignees, as applicable) may disclose to any and all Persons, without limitation of any kind, the tax treatment and tax structure of the Corporate Taxpayer, the Change Shareholder Representatives and their Affiliates, and any of their transactions, and all materials of any kind (including opinions or other tax analyses) that are provided to the Change Shareholder Representatives relating to such tax treatment and tax structure.

If the Change Shareholder Representatives or an assignee commits a breach, or threatens to commit a breach, of any of the provisions of this Section 7.12, the Corporate Taxpayer shall have the right and remedy to have the provisions of this Section 7.12 specifically enforced by injunctive relief or otherwise by any court of competent jurisdiction without the need to post any bond or other security, it being acknowledged and agreed that any such breach or threatened breach shall cause irreparable injury to the Corporate Taxpayer or any of its Subsidiaries and the accounts and funds managed by the Corporate Taxpayer and that money damages alone shall not provide an adequate remedy to such Persons. Such rights and remedies shall be in addition to, and not in lieu of, any other rights and remedies available at law or in equity.

IN WITNESS WHEREOF, the Corporate Taxpayer, Echo, the JV and the Change Shareholder Representatives have duly executed this Agreement as of the date first written above.
