Section 3.02. Additional Capital Contributions. 

(a) From and after the Closing, no Member shall be required to make any additional capital contributions to the Company except as provided in
this Article 3. 
 (b) After the Closing, subject to Section 3.07 and
Section 5.05, Members may from time to time make capital contributions to the Company (each, an “Additional Capital Contribution”) at such times and in such amounts and such price per Unit, if applicable,
as the Board may determine to offer to or accept from the Members. 
 Section 3.03. Issuance of Units. 

(a) No Units or other Equity Securities of the Company shall be issued in respect of any Additional Capital Contribution until such Additional

 20 

 (b) Subject to Section 3.07 and
Section 5.05, the Board may authorize the Company to issue additional Units and/or create and issue new series, types or classes of Equity Securities of the Company with such voting powers, full or limited, or no voting
powers, and such designations, preferences and relative, participating, optional or other special rights, and qualifications, limitations or restrictions thereof as the Board may determine, and authorize obligations, evidences of indebtedness or
other securities or interests of the Company convertible, exercisable or exchangeable into Units or other Equity Securities of the Company, in each case to any Person in such amounts and on such terms as so approved by the Board; provided,
that (other than an issuance made under Section 3.03(c)) any such issuance will be made only in exchange for payment of Fair Market Value for such interest, as determined in the reasonable good faith judgment of the Board.
The Company may issue whole or fractional Units or other Equity Securities of the Company. 
 (c) The Company and Echo agree to cooperate to
ensure that the Echo Ratio is maintained at one Unit to one Echo Share for so long as any MCK Member (or their Permitted Transferees) holds Units. In connection therewith (and subject to Section 5.05 and 11.04(d)):

 (i) From and after the date hereof, and at all times that any MCK Member (or its Permitted Transferees) holds Units, if at
any time Echo issues an Echo Share (including in a Qualified IPO) or any other Equity Security of Echo (other than the share of Class X Stock (as defined in the Echo Shareholders Agreement)), in accordance with the terms of this Agreement,
(A) the Company shall issue to Echo one Unit (for each Echo Share issued) or one such other Equity Security of the Company (for each other Equity Security issued) corresponding to the Equity Security issued by Echo, and with the rights to
dividends and distributions and other economic rights as are determined by the Board in good faith to correspond to those of the Equity Security issued by Echo, and (B) the net proceeds received by Echo with respect to the corresponding Echo
Share or other Equity Security of Echo, if any, shall be concurrently transferred to the Company; provided that if Echo issues any Echo Shares pursuant to an Exchange or pursuant to the conversion of SpinCo stock contemplated by the Merger
Agreement, then the Company shall not issue any new Units in connection therewith; provided further that in the event that the Fair Market Value of the corresponding Echo Share or other Equity Security of Echo, as determined by the Board in
good faith, exceeds the net proceeds received by Echo with respect to such Echo Share or other Equity Security of Echo, then solely for purposes of Section 3.05 and Section 8.01, (u) Echo shall be
treated as having made a Capital Contribution to the Company equal to such Fair Market Value and (v) such excess shall be treated as an item of Loss. Notwithstanding the foregoing, this Section 3.03(c)(i) and
Section 3.03(c)(ii) shall not apply (1) to the issuance and distribution to holders of Echo Shares of rights to purchase Equity Securities of Echo under a “poison pill” or similar shareholders’ rights
plan approved under Section 11.04(d) (it being understood that (x) upon the exchange of Units for Echo Shares, such Echo Shares will be issued together with any such corresponding right and (y) upon issuance of
Echo Shares in connection with exercise of a “poison pill” or similar shareholders’ rights plan approved under Section 11.04(d), the Company will issue an equal number of Units as provided in this
Section 3.03) or (2) to the issuance under 

  
 21 

 
any Approved Echo Plan of any Equity Securities of Echo approved by the Board or any authorized committee of the Board (each, an “Approved Issuance”) that are convertible,
exercisable for or exchangeable into Echo Shares, but shall in each of the foregoing cases, apply to the issuance of Echo Shares in connection with the conversion, exercise or exchange of such Equity Securities of Echo issued in connection with an
Approved Issuance (for cash or other consideration in accordance with their terms or otherwise). In addition, this Section 3.03(c)(i) and Section 3.03(c)(ii) shall not apply to an Approved Issuance
under an Approved Echo Plan of any Echo Shares that are unvested, but shall apply upon the vesting of any such Echo Share. Except for transactions pursuant to an Exchange or the conversion of SpinCo stock contemplated by the Merger Agreement,
following the Closing and for so long as any MCK Member (or its Permitted Transferees) hold Units, the Company shall not issue any additional Units of the Company to Echo unless substantially simultaneously therewith Echo issues or sells, to a
Person other than Echo and subject to the terms of this Agreement, an equal number of Echo Shares. This Section 3.03(c)(i) shall not apply to any adjustments pursuant to Section 2.03, Section 6.03, or
Section 8.06 of the Contribution Agreement. 
 (ii) Following the Closing and for so long as any MCK Member (or its
Permitted Transferees) holds Units, Echo may not redeem, repurchase or otherwise acquire any Echo Shares unless the Company substantially simultaneously redeems, repurchases or otherwise acquires from Echo an equal number of Units for the same price
per security, and Echo may not redeem, repurchase or otherwise acquire any other Equity Security of Echo unless the Company substantially simultaneously redeems, repurchases or otherwise acquires from Echo an equal number of any outstanding
corresponding Equity Securities of the Company of the corresponding class or series for the same price per security; provided that if Echo is required to redeem or repurchase any Echo Shares, including but not limited to any redemption
pursuant to the terms of the Echo Shareholders Agreement, the Company shall substantially simultaneously redeem, repurchase or otherwise acquire from Echo an equal number of Units for the same price per security (provided that, if such
repurchase, redemption or acquisition is prohibited by applicable Law, such repurchase, redemption or acquisition may be delayed by the Company until such time as it is not prohibited by applicable Law and appropriate adjustment shall be made to the
economic and other arrangements set forth herein so as to, to the greatest extent possible, treat such Unit as having been redeemed at the time it otherwise would have been redeemed). The Company may not, following the Closing and so long as any MCK
Member (or its Permitted Transferees) holds Units, redeem, repurchase or otherwise acquire any Units from Echo unless substantially simultaneously Echo redeems, repurchases or otherwise acquires an equal number of Echo Shares for the same price per
security from holders thereof, and the Company may not redeem, repurchase or otherwise acquire any other Equity Securities of the Company from Echo unless substantially simultaneously Echo redeems, repurchases or otherwise acquires an equal number
of Equity Securities of Echo of a corresponding class or series for the same price per security. Notwithstanding the foregoing, to the extent that any consideration payable by Echo in connection with the redemption or repurchase of any Echo Shares
or other Equity Securities of Echo consists (in whole or in part) of Echo Shares or such other Equity Securities of Echo (including in connection with the cashless exercise of an option or warrant), then the redemption or repurchase of the
corresponding Units or other Equity Securities of the Company shall be effectuated in an equivalent manner. This Section 3.03(c)(ii) shall not apply to any adjustments pursuant to Section 2.03, Section 6.03, or
Section 8.06 of the Contribution Agreement. 

  
 22 

 (iii) Following the Closing and so long as any MCK Member (or its Permitted
Transferees) holds Units, Echo shall not in any manner effect any subdivision (by any stock split, stock dividend, reclassification, recapitalization or otherwise) or combination (by reverse stock split, reclassification, recapitalization or
otherwise) or other similar restructuring in respect of the Echo Shares unless such action is taken concurrently with a corresponding subdivision or combination or other similar restructuring of the Units (with corresponding changes made with
respect to any other convertible, exercisable or exchangeable securities), such that the Echo Ratio is maintained at one Unit to one Echo Share. Following the Closing and so long as any MCK Member (or its Permitted Transferees) holds Units, the
Company shall not in any manner effect any subdivision (by any stock split, stock dividend, reclassification, recapitalization or otherwise) or combination (by reverse stock split, reclassification, recapitalization or otherwise) or other similar
restructuring of Echo (with corresponding changes made with respect to any other convertible, exercisable or exchangeable securities), such that the Echo Ratio is maintained at one Unit to one Echo Share. 

(iv) In the event of any adjustments pursuant to Section 2.03, Section 6.03, or Section 8.06 of the Contribution
Agreement that results in a change in the Membership Percentages of the Members (such changed percentage, the “Adjusted Membership Percentage”), the parties and the Company agree to issue, redeem, repurchase, subdivide (by any unit
split, unit distribution, reclassification, recapitalization or otherwise), combine (by reverse unit split, reclassification, recapitalization or otherwise) or otherwise acquire or cancel Units such that following the adjustment Echo owns an
aggregate number of Units of the Company such that the Echo Ratio is one Unit to one Echo Share and the Membership Percentage equals the Adjusted Membership Percentage. 

Section 3.04. Withdrawal of Capital. 

(a) No Member shall be entitled to withdraw any part of its Capital Contributions or to receive any distribution from the Company, except as
expressly provided herein. Under circumstances requiring the return of any Capital Contribution, no Member shall have the right to demand or receive property other than cash, except as expressly provided herein. No Member shall have the right to
cause the sale of any Company asset, except as expressly provided herein. No Member shall have any right to receive any salary or draw with respect to its Capital Contributions or its Capital Account or for services rendered on behalf of the Company
or otherwise in its capacity as a Member. 
 (b) No Member shall have any liability for the return of the Capital Contributions of any other
Member. Except as otherwise required by Law, no Member shall be required to make up a negative balance in its Capital Account. Except as expressly provided herein or to the extent granted by Equity Securities of the Company hereinafter approved by
the Board pursuant to Section 3.03(b), no Member shall have priority over any other Member either as to the return of the amount of such Member’s Capital Contributions or as to any allocation of any item of income,
gain, loss, deduction or credit of the Company. 

  
 23 

 Section 3.05. Maintenance of Capital Accounts. 

(a) The Company shall maintain a separate capital account for each Member according to the rules of Treasury Regulation Section 1.704-1(b)(2)(iv) (a “Capital Account”). The initial Capital Account balances of the Initial Members shall be as set forth on Schedule I. 

(b) No Member shall be required to make any payment to any other Member or the Company by reason of any deficit or negative balance which may
exist from time to time in such Member’s Capital Account (including upon and after dissolution of the Company). 
 (c) Upon a Transfer
of all or a portion of any Equity Security of the Company in accordance with the terms of this Agreement (other than, for the avoidance of doubt, adjustments pursuant to Section 2.03, Section 6.03 or Section 8.06 of the Contribution
Agreement, which shall be addressed by Section 3.05(d) below), the transferee Member shall succeed to the Capital Account of the transferor which is attributable to such equity interest or portion thereof. 

(d) In the event of adjustments to the Membership Percentages pursuant to Section 2.03, Section 6.03 and/or Section 8.06 of the
Contribution Agreement, appropriate corresponding adjustments, as reasonably determined by the Board in its sole discretion, shall be made to the Members’ Capital Accounts to reflect the treatment of adjustments pursuant to Section 2.03,
Section 6.03 and/or Section 8.06 of the Contribution Agreement as adjustments to the Fair Market Values of the assets contributed to the Company pursuant to the Contribution Agreement. 

Section 3.06. No Interest. No interest shall be paid on Capital Contributions or on the balance in a Member’s Capital
Account. 
 Section 3.07. Preemptive Rights. 

(a) Other than with respect to the Equity Securities of the Company described in Section 3.07(f), 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 of the Company at least twenty (20) Business Days prior
to the proposed issuance date. The Issuance Notice shall specify the price at which such Equity Securities of the Company are to be issued and the other material terms of the issuance (including the terms of the Equity Securities of the Company
proposed to be issued). Subject to Section 3.07(f), each of the Initial Members shall be entitled to purchase (or to cause its Affiliates to purchase) up to its respective Membership Percentage of the Equity Securities of
the Company proposed to be issued, at the price and on the terms specified in the Issuance Notice. 
 (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 of the Company 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 of the Company 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 of the Company 

  
 24 

 
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 of the Company 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 of the Company. 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”). 

(c) If an Initial Member (or its Permitted Transferees) fails to exercise its preemptive rights under this
Section 3.07 or elects to exercise such rights with respect to less than its Membership Percentage of the issuance and another Member has exercised its rights under this Section 3.07 with respect
to its entire Membership Percentage, such other Member shall be entitled to purchase, or have its Affiliates purchase, from the Company any or all of the remaining portion of the issuance. 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 of the Company that the Initial Members (or their 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 of the Company 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 of the Company the Company shall issue certificates or other appropriate
instruments representing the Equity Securities of the Company 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 of the Company in accordance with the terms and conditions as specified in the Issuance Notice. 

  
 25 

 (f) Notwithstanding the foregoing, no Initial Member (or its Permitted Transferees) shall be
entitled to purchase Equity Securities of the Company as contemplated by this Section 3.07 in connection with issuances of Equity Securities of the Company (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 conversion, exercise or exchange of Equity Securities of the
Company granted pursuant to any such plans or arrangements or outstanding as of the date hereof), (ii) in connection with a Qualified IPO in accordance with the terms of this Agreement, (iii) pursuant to conversion, exercise or exchange of any
convertible, exchangeable or exercisable Equity Securities of the Company issued in compliance with the terms of this Agreement, (iv) pursuant to any exercise of the Top-up Option under
Section 10.06 below, (v) pursuant to equity adjustments as required under Section 2.03, Section 6.03 and Section 8.06 of the Contribution Agreement, (vi) pursuant to
Section 8.02(a)(ix), or (vii) pursuant to an issuance of Equity Securities of the Company pursuant to Section 3.03(c). The Company shall not be obligated to consummate any proposed issuance of
Equity Securities of the Company, nor be liable to any Initial Member (or its Permitted Transferees) if the Company has not consummated any proposed issuance of Equity Securities of the Company, 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. 

(g) This Section 3.07 shall terminate upon consummation of a Qualified IPO.

Company by the Company’s Secretary. Such further notice shall be given as may be required by Law, but meetings may be held without notice if all the Members entitled to vote at the meeting are present in person or represented by proxy or if
notice is waived in writing by those not present, either before or after the meeting. Presence at a meeting by a Member shall constitute a waiver of any deficiency of notice, except when a Member attends the meeting for the express purpose of
objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not called or convened in accordance with this Agreement. 

Section 4.06. Quorum; Telephonic Meetings. 

(a) Provided that notice of the meeting has been given in accordance with Section 4.05, Members holding a majority of
the outstanding Units entitled to vote with respect to the business to be transacted, who shall be present or represented by proxy at any meeting duly called, shall constitute a quorum for the transaction of business. If less than a quorum shall be

promptly give notice of when the meeting will be reconvened. 
 (b) Members may, and shall be entitled to, participate in meetings of the
Members by means of conference telephone or similar communications equipment by means of which all Persons participating in the meeting can hear each other. Participation in a telephonic meeting pursuant to this
Section 4.06(b) shall constitute presence at such meeting for purposes of Section 4.06(a) and shall constitute a waiver of any deficiency of notice, except when a Member attends the meeting for the

(a) At any meeting of the Members, each Member entitled to vote on any matter coming before the meeting shall, as to such matter, have a vote,
in person, by telephone or by proxy, equal to the number of Units held in its name on the relevant record date established pursuant to Section 4.09. All Units shall constitute a single class and group of Equity Securities
of the Company and the holders of Units shall vote together as a single class and group of Members. 

  
 27 

 (b) Subject to Section 5.05, when a quorum is present, the
affirmative vote or consent of Members holding a majority of the outstanding Units present in person or represented by proxy at a duly called meeting and entitled to vote on the subject matter shall constitute the act of the Members. Every proxy
shall be in writing, dated and signed by the Member entitled to vote or its duly authorized attorney-in-fact. 

Section 4.08. Action Without a Meeting. 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. If
no record date is fixed for the determination of Members entitled to notice of or to vote at a meeting of Members, or Members entitled to receive payment of a distribution, the date on which notices of the meeting are mailed or faxed or the date on
which the resolution of the Board declaring such distribution is adopted, as the case may be, shall be the record date for such determination of Members. 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. 
 Section 4.10. Member Approval Rights. Except as otherwise expressly set forth in this
Agreement or as required by Law, the Members shall have no right to vote on any matter and hereby expressly waive any right to vote that can be waived.

Company’s property. 
 Section 4.12. Liability. Except as otherwise set forth herein or in the Contribution Agreement, or
the Transaction Documents or as required by the Act, the debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and no Member,
Director or Company officer shall be obligated personally for any such debt, obligation or liability of the Company or for any losses of the Company solely by reason of being a Member or acting as a Director or Company officer. For the avoidance of
any doubt, neither MCK nor any of the Echo Shareholders (or any of MCK and Echo Shareholders’ respective Affiliates) shall be required to be a guarantor for any indebtedness of the Company.

Director, the party designating such Nominee Director shall promptly provide written notice to the other parties and the Company. For the avoidance of doubt, immediately following a Qualified MCK Exit, the MCK Members shall no longer have any
designation rights pursuant to this Article 5. 

  
 30 

 (e) At any such time as one of the MCK Directors serves as the Chairman of the Board, Echo
shall be entitled to appoint the Vice Chairman of the Board from one of the Echo Directors. At any such time as one of the Echo Directors serves as the Chairman of the Board, the MCK Members shall be entitled to appoint the Vice Chairman of the
Board from one of the MCK Directors. 
 (f) Each of the Company and each Member shall take all necessary action to effectuate the provisions
of Section 5.01(b), Section 5.01(c), Section 5.01(d) and Section 5.01(e) to ensure that the Board consists of the Directors who are duly
designated, elected or appointed (and/or removed pursuant to Section 5.01(c)) in accordance with such Section, including by promptly calling and/or voting, as applicable, in any meetings or promptly participating in an
action by written consent. 
 (g) The Board, by taking action in accordance with this Article 5, and subject to compliance with
Section 5.05, shall have the power, discretion and authority on behalf and in the name of the Company to carry out any and all of the objects and purposes of the Company contemplated by this Agreement and to perform or
authorize all acts which it may deem necessary or advisable in connection therewith. The Members agree that all determinations, decisions and actions made or taken by the Board in accordance with this Article 5, and subject to compliance with
Section 5.05, shall be conclusive and absolutely binding upon the Company, the Members and their respective successors, assigns and personal representatives (without requirement for further consent or other action by the
Members). 
 (h) Each Director, other than the Directors who meet the Independence Requirements, will serve as such without compensation from
the Company or any of its Subsidiaries. Each of the Directors that meet the Independence Requirements shall be paid reasonable compensation for their service on the Board in an amount determined by the Board from time to time. Each Director and
observer shall be entitled to reimbursement from the Company for reasonable out-of-pocket expenses incurred by such Director or observer during the course of performing
his or her duties as a Director or exercising his or her rights as an observer. 
 (i) No Director (acting in his or her capacity as such)
shall have any right or authority to act on behalf of or to bind the Company with respect to any matter except pursuant to a resolution of the Board authorizing such action, which resolution is duly adopted by the Board by the affirmative vote
required for such matter pursuant to the terms of this Agreement. 
 (j) Each Director may authorize another individual (who may or may not
be a Director, but shall meet the criteria for designation as a Director by the Member that designated such Director) to act for such Director by proxy at any meeting of the Board, or to consent to or dissent from any proposed action of the Board in
writing without a meeting thereof. A writing authorizing any individual to act for any Director by proxy, which has been executed by such Director and entered into the books and records of the Company, shall be a valid means by which a Director may
grant such authority. 

  
 31 

 (k) H&F shall have the right, exercisable by delivering notice to the Company, to
designate one (1) non-voting observer to attend any meetings of the Board, the Ad Hoc Committee, the IPO Committee, the boards of directors and equivalent governing bodies of the Company’s
Subsidiaries and any other committees thereof. Notice of meetings of the Board, the Ad Hoc Committee, the IPO Committee, the boards of directors and equivalent governing bodies of the Company’s Subsidiaries and any other committees thereof
shall be furnished (together with all materials to be provided) to such observer no later than, and using the same form of communication as, notice of meetings of the Board, the Ad Hoc Committee, the IPO Committee, the boards of directors and
equivalent governing bodies of the Company’s Subsidiaries and any other committees thereof, as the case may be, that are furnished to the members of the Board, the Ad Hoc Committee, the IPO Committee, the boards of directors and equivalent
governing bodies of the Company’s Subsidiaries and any other committees thereof, respectively; provided, that the Company or its Subsidiaries, as the case may be, shall be entitled to remove such observer from such portions of a meeting
of the Board, the Ad Hoc Committee, the IPO Committee, the boards of directors or equivalent governing bodies of any of the Company’s Subsidiaries or any other committees thereof, in each case, to the extent such observer’s presence would
be likely to result in the waiver of any attorney client privilege. Any observer designated under this Section 5.01(k) shall be permitted to attend any meeting of any of the Board, the Ad Hoc Committee, the IPO Committee,
the boards of directors and equivalent governing bodies of the Company’s Subsidiaries and any other committees thereof, in each case, using the same form of communication permitted for members of such Board, Ad Hoc Committee, IPO Committee,

Section 5.02. Removal and Resignation. 

(a) (A) Each Member shall have the exclusive right to remove, with or without cause, any Director that such Member has the right to
designate and (B) the Members shall have the right to remove any Director they mutually have the right to designate upon their mutual consent, in each case upon the giving of written notice to such Director and the Board; provided, that
(i) such rights shall only be available to the MCK Members until the consummation of a Qualified MCK Exit and (ii) each Member agrees to remove any Director designated by such Member if such Director is or becomes a Restricted Person or,
with respect to any independent Director, such Director fails to satisfy the Independence Requirements. 
 (b) Any Director may resign by
written notice to the Board. Unless otherwise specified therein, a Director’s resignation shall take effect upon delivery of such notice. 

(c) Vacancies created on the Board resulting from the death, disability, resignation or removal of a MCK Director or an Echo Director shall be
filled by the Member that designated such Nominee Director, with such appointment to become effective immediately upon delivery of written notice of such appointment to the other Members and the Company, provided, that this right shall be
applicable to the MCK Members with respect to appointments of MCK Directors solely prior to consummation of a Qualified MCK Exit. Vacancies created on the Board resulting from the death, disability, resignation or removal of the Mutual Independent
Director (or any other directors who are not Nominee Directors) shall be filled (A) solely by the mutual consent of the MCK Members and Echo, in each case to the extent they (together with their respective Permitted

  
 32 

 
Transferees) hold 10% or more of the MCK Units or Echo Units, respectively, or (B) in the event either the MCK Members or Echo hold less than 10% of the MCK Units or Echo Units,
respectively, upon the approval of the holders of a majority of the Units at such time, with such appointment, in each case, to become effective immediately upon delivery of written notice of such appointment to the other Members and the Company.

 Section 5.03. Meetings of the Board. 

(a) The Board shall hold a regularly scheduled meeting at least once every calendar quarter at such place, date and time as the Board may
designate. Special meetings of the Board may be called at any time by the Chairman. Special meetings of the Board shall be called at any time by the Chairman upon the written request of at least one Director to the Chairman, specifying the matters
to be discussed. 
 (b) Notice of any meeting of the Board or any committee thereof stating the place, date and hour of the meeting and the
purpose or purposes for which the meeting is called shall be given to each Director by telephone, electronic mail or facsimile no less than seven days before the date of the meeting; provided, that the Chairman may reduce the advance notice
period for any special meeting to no less than two days if the Chairman determines, acting reasonably and in good faith, that it is necessary or desirable to take action within a time period of less than seven days; and provided,
further, that for the avoidance of doubt, if notice of any meeting of the Board is not given in accordance with this Section 5.03(b), then no business may be transacted at such meeting. Notice of any meeting may be
waived by any Director on behalf of such Director. Presence at a meeting of the Board by a Director shall constitute waiver of any deficiency of notice of such meeting by such Director, unless such Director objects, at the beginning of the meeting,
to the transaction of any business at such meeting because such meeting was not called or convened in accordance with this Agreement. 
 (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. 
 (d) The presence in person or by proxy of a number of Directors equal to a majority of the total
number of Directors on the Board at such time shall constitute a quorum for the conduct of business at any meeting of the Board, provided, that such quorum consists of not less than two MCK Directors and two Echo Directors. If a quorum is not
present at any meeting of the Board, no business may be conducted at such meeting (the “Original Meeting”), and the Directors present shall adjourn the meeting and promptly give notice of when it will be reconvened, which shall not
be more than thirty (30) days from the date of the meeting (the “Adjourned Meeting”). 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. 

  
 33 

 (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. Participation in any meeting of the Board pursuant to this Section 5.03(e)
shall constitute presence in person at such meeting for purposes of Section 5.03(d) and shall constitute a waiver of any deficiency of notice of such meeting, unless such Director objects, at the beginning of the meeting,
to the transaction of any business at such meeting because such meeting was not called or convened in accordance with this Agreement. 
 (f)
Each Director shall be entitled to cast one vote with respect to each matter brought before the Board (or any committee thereof of which such Director is a member) for approval. Except as otherwise expressly provided by this Agreement, the
affirmative vote of Directors entitled to cast a majority of the votes that may be cast by the Directors in attendance at any meeting at which a quorum is present (whether in person or by proxy) shall be required to authorize any action by the Board
and shall constitute the action of the Board for all purposes. No Director shall be disqualified from voting on any matter as to which the Member that designated such Director or any of its Affiliates may have an interest. Subject to
Section 6.02(b), notwithstanding any duty otherwise existing at Law or in equity, to the fullest extent permitted by Law, no Director shall have any duty to disclose to the Company or the Board confidential information of
the Member that designated such Director or any of its Affiliates in such Director’s possession, even if such information is material and relevant to the Company and/or the Board, and in any case, such Director shall not be liable to the
Company or the other Members or their respective Affiliates for breach of any duty (including the duty of loyalty or any other fiduciary duty) as a Director by reason of not disclosing such confidential information; provided, that the
foregoing shall not limit the Chief Executive Officer’s or any other employee of the Company or its Subsidiaries who is a Director’s responsibility to disclose to the Board information regarding the Company and its Subsidiaries obtained as
a result of the Chief Executive Officer or such employee serving in such capacity. 
 (g) The Secretary or, if he or she is not present, any
individual whom the Chairman may appoint, shall keep minutes of each meeting of the Board, which shall reflect all actions taken by the Board thereat. 

(h) The Board may establish other provisions and procedures relating to the governance of its meetings that are not in conflict with the terms
of this Agreement. 
 (i) Each Director shall be entitled to receive all information (including without limitation, board minutes, board

of the Board, and in each case, the Nominee Directors appointed by the other party have not consented to such proposed resolution or written consent, with the effect that such proposed resolution or written consent has not been approved by the Board
(each such event, a “Board Escalation Matter”), then at the written request of either MCK Member or Echo, an ad hoc committee comprising of two representatives of the MCK Members and two representatives of Echo (the
“Ad Hoc Committee”), shall be formed and such Ad Hoc Committee shall meet (in person, by telephone or by audio-visual conference) and seek to resolve such matters within thirty (30) days after the occurrence of the Board

(a) to the extent a Subsidiary board includes one or more MCK Directors or other designee(s) of MCK, the Company shall take all action necessary to cause such Subsidiary board to also include a number of members designated by Echo such that such

(b) The Chief Executive Officer may, from time to time, employ and retain Persons as may be necessary or appropriate for the conduct of the
Company’s business (subject to the supervision and control of the Board, and subject to the approval rights set forth in Section 5.05), including employees, agents and other Persons (any of whom may be a Member or
Representative) who may be designated as officers of the Company, with titles including, but not limited to, “chief financial officer,” “chief operating officer,” “chief compliance officer,” “president,”
“vice president,” “treasurer,” “secretary” and “general counsel,” as and to the extent authorized by the Board. Any number of offices may be held by the same Person. The Board may choose not to fill any office
for any period as it may deem advisable. Officers need not be residents of the State of Delaware or Members. Any officers so designated shall have such authority and perform such duties as the Board and the Chief Executive Officer, from time to
time, may delegate to them. The Chief Executive Officer may assign titles to particular officers. Each officer shall hold office until his successor shall be duly designated or until his or her death or until he or she shall resign or shall have
been removed in the manner hereinafter provided. 
 (c) Any officer may resign as such at any time. Such resignation shall be made in writing
and shall take effect at the time specified therein, or if no time is specified, at the time of its receipt by the Board. The acceptance by the Board of a resignation of any officer shall not be necessary to make such resignation effective, unless
otherwise specified in such resignation. Any officer may be removed as such, either with or without cause, at any time by the Board. Subject to Section 5.05, vacancies may be filled by approval of the Board. Designation of
any Person as an officer by the Board shall not in and of itself vest in such Person any contractual or employment rights with respect to the Company.

the purpose of the Company’s business, and the actions of the officers taken in accordance with such powers shall bind the Company. Any Person dealing with the Company may rely upon a certificate signed by any officer as to: (A) the

 ARTICLE 6 

DUTIES, EXCULPATION AND INDEMNIFICATION 

Section 6.01. Duties, Exculpation and Indemnification. 

(a) Notwithstanding any duty otherwise existing at Law or in equity, to the fullest extent permitted by Law and except as expressly
contemplated by this Agreement or any other agreement entered into between a Covered Person, and any Member or the Company or any of its Subsidiaries, no Covered Person shall have any duty (including any fiduciary duty) otherwise applicable at Law
or in equity to the Company or to any other Member with respect to or in connection with the Company or the Company’s business or affairs. 

(b) To the fullest extent permitted by Law, no Person made or threatened to be made a party to any action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that such Person is or was a member, shareholder, partner, Director or executive officer of any Member, the Company or any of their respective Subsidiaries or Affiliates (collectively,
“Covered Persons”) shall be liable to the Company or its Subsidiaries or to any other Person that is a party hereto or is otherwise bound hereby for any act or failure to act in such Person’s capacity as Covered Person, except, in the
case of any Covered Person who is not an officer or other employee of the Company, willful misconduct or breach of this Agreement or any other agreement to which such Covered Person is a party and, in the case of any Covered Person who is an officer
or other employee of the Company willful misconduct, gross negligence, bad faith or breach of this Agreement or any other agreement to which such Covered Person is a party. The Board shall also have the power to exculpate, to the same extent set
forth in this Section 6.01(b), employees of the Company or its Subsidiaries who are not Covered Persons and agents of the Company or its Subsidiaries. 

(c) Except in the case of willful misconduct (with respect to any Covered Person who is not an officer or other employee of the Company) or
willful misconduct, gross negligence or bad faith (with respect to any Covered Person who is an officer or other employee of the Company), or in the case of a breach of this Agreement or any other agreement with the Company or its Subsidiaries to
which any such Covered Person is a party, each Person (and the heirs, executors or administrators of such Person) who was or is a party or is threatened to be made a party to, or is involved in any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, in such Person’s capacity as a Covered Person, and such action, suit or proceeding relates to an act or omission of such Covered Person acting in its capacity as such, shall
be indemnified and held harmless by the Company to the fullest extent permitted by the Laws of the State of Delaware (including indemnification for acts or omissions constituting negligence, gross negligence or breach of duty); provided, that
the foregoing indemnification shall not be available to a Member in the case of an action, suit or proceeding brought by a Member or any other party to this Agreement against such Member. The right to indemnification conferred in this
Section 6.01(c) shall also include the right to be paid by the Company the expenses incurred in connection with any such action, suit or proceeding in advance of its final disposition to the fullest extent authorized by the
Laws of the State of Delaware; provided, that the payment of such expenses in advance of the final disposition of an action, suit or proceeding shall be made only upon delivery to the Company of an undertaking by or on behalf of the
applicable Covered Person to repay all amounts so paid in advance if it shall ultimately be 

  
 42 

 
determined that such Covered Person is not entitled to be indemnified under this Section 6.01(c) or otherwise. The rights to indemnification and advancement conferred in
this Section 6.01(c) constitute contract rights. 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). The Company shall also have the power to indemnify and hold harmless to the same extent set forth in this Section 6.01(c) employees of the Company or its
Subsidiaries who are not Covered Persons and agents of the Company or its Subsidiaries. 
 No claim subject to the indemnification provisions hereunder
shall be settled by any Covered Person without the consent of the Company, not to be unreasonably withheld. 
 (d) The Company may, by action
of the Board, provide indemnification to such officers, employees and agents of the Company or other Persons who are or were serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise to such extent and to such effect as the Board shall determine to be appropriate. 
 (e) The Company
shall, by action of the Board, have the power to purchase and maintain insurance on behalf of any Person who is or was a Covered Person or is or was serving at the request of the Company as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss incurred by such Person in any such capacity or arising out of his status as such, whether or not the Company would have the power to indemnify
him against such liability under the Laws of the State of Delaware. 
 (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. 

  
 43 

 (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. 

Section 6.02. Other Activities; Business Opportunities. 

(a) Notwithstanding any duty otherwise existing at Law or in equity, to the fullest extent permitted by Law, and subject only to
Section 11.04, no Member, Affiliate of any Member, Director or Company officer who is also an employee of a Member or an Affiliate of a Member (in each case only when acting on behalf of such Member or such Member’s
Affiliate in connection with such Member’s or such Member’s Affiliate’s own business and operations) shall have any 

  
 44 

 
obligation to refrain from, directly or indirectly, (i) engaging in the same or similar activities or lines of business as the Company or developing or marketing any products or services
that compete, directly or indirectly, with those of the Company, (ii) investing or owning any interest, publicly or privately, in, developing a business relationship with, or serving as an employee, officer, director, consultant or agent of,
any Person engaged in the same or similar activities or lines of business as, or otherwise in competition with, the Company or (iii) doing business with (directly or as an employee, officer, director, consultant or agent of a Person who does
business with) the Company or any Person who conducts business with the Company; and neither the Company nor any Member (or Affiliate of any Member) shall have any right in or to, or to be offered any opportunity to participate or invest in, any
business or venture engaged or to be engaged in by any other Member, Affiliate of any other Member, officer of the Company who is also an employee of any other Member (or an Affiliate of any other Member) or Director or shall have any right in or to
any income or profits derived therefrom. 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 the position of Chairman of the Board, Executive Vice Chairman of the Board or any other Board-level position.

the contrary, the Chief Executive Officer or another officer of the Company to whom the Chief Executive Officer has delegated such authority shall determine the institution or institutions at which the Company’s bank accounts will be opened and
maintained, the types of accounts, and the Persons who will have authority with respect to the accounts and the funds therein. 

Section 7.03. Books of Account and Other Information. The Company shall prepare and maintain, at its principal place of business,
separate books of account for the Company that shall show a true and accurate record of all costs and expenses incurred, all charges made, all credits made and received and all income derived in connection with the operation of the Company’s
business in accordance with GAAP and this Agreement. All questions of accounting shall be determined by the Board or a committee or officer authorized by the Board to make such determination. 

Section 7.04. Certain Tax Matters. 

(a) At all times during which the Company has two or more Members, the Members intend that the Company shall be treated as a partnership for
U.S. federal, state and local tax purposes, and the Members shall take such actions and make such elections (or refrain from taking any actions or elections) as may be necessary to achieve the foregoing. 

(b) The Company shall (i) timely (taking into account extensions) prepare and file, or cause to be prepared and filed, all tax returns of
the Company (it being understood that the procedures for tax return preparation shall be governed by Section 7.04(d)) and (ii) use commercially reasonable efforts to deliver Schedules
K-1 to each Member as soon as practicable after the end of each Tax Year but not later than September 30 of the following Tax Year. 

(c) The “tax matters partner” of the Company for purposes of Section 6231(a)(7) of the Code, and the “partnership
representative” for purposes of the Partnership Tax Audit Rules, shall be appointed, and may be removed, by the Board from time to time (the “Tax Matters Member”). 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). The Tax Matters Member shall inform
the Board and each other Member of all significant matters that come to its attention in its capacity as Tax Matters Member by giving notice thereof on or before the fifth day after becoming aware thereof and, within that time, shall forward to the
Board and each such other Member copies of all significant written communications it may receive in that capacity. 
 (d) The Tax Matters
Member shall: (i) supervise the timely preparation and filing of all tax returns of the Company (taking into account extensions); provided that the Board may (1) select from time to time the third-party tax return preparer (the
“Return Preparer”) for the Company (or, if the Tax Matters Member does not engage an outside tax return preparer for any such tax return, the Return Preparer may be engaged to review such tax return on behalf of the Board) and
(2) designate certain individuals or groups at the Return Preparer to act in such capacity. Initially, the Return Preparer shall be Deloitte LLP; provided, further that the Tax Matters Member shall be permitted to engage advisors
other than the Return Preparer from time to time as 

  
 46 

 
the Tax Matters Member reasonably determines to be necessary or helpful to the satisfaction of the Tax Matters Member’s responsibilities hereunder, subject in all events to the preparation
and/or review of tax returns by the Return Preparer as set forth in clause (1) above; (ii) manage and control any administrative proceeding with the Internal Revenue Service or any other taxing authority or any judicial proceeding, in each case
relating to the determination of any item of income, gain, loss, deduction or credit of the Company for U.S. federal, state, local or foreign income or franchise tax purposes; provided, the Tax Matters Member shall not enter into any
settlement relating to income or franchise taxes that is binding on the Company without prior approval by the Board; (iii) cause the Company to make all tax elections required or permitted to be made by the Company under applicable Law;
provided, that for each Tax Year ending on or after the date hereof, the Company shall have in effect a valid election under Section 754 of the Code; and (iv) use commercially reasonable efforts to keep the Board reasonably informed
of all material matters that come to its attention in its capacity as Tax Matters Member; 
 (e) Except as expressly provided herein, the Tax
Matters Member shall take no action on behalf of the Company without the authorization of the Board, other than such action as may be required by applicable Law, and shall take actions on behalf of the Company as directed by the Board. Any
reasonable cost or expense incurred by the Tax Matters Member in connection with its duties, including the preparation for or pursuance of administrative or judicial proceedings, shall be paid by the Company. 

(f) No Member shall file a request pursuant to Code Section 6227 for an administrative adjustment of Company items for any taxable year
without first notifying the other Members and obtaining the approval of the Board. If the Board approves the requested adjustment, the Tax Matters Member shall file the request for the administrative adjustment on behalf of the Members. If such
consent is not obtained within 30 days from such notice, or within the period required to timely file the request for administrative adjustment, if shorter, any Member, including the Tax Matters Member, may file a request for administrative
adjustment on its own behalf. Any Member intending to file a petition under Code Sections 6226 or 6228 (or another Code Section) with respect to any item involving the Company shall notify the Board and the other Members of such intention and the
nature of the contemplated proceeding. In the case where the Tax Matters Member is the Member intending to file such petition on behalf of the Company, such notice shall be given within a reasonable period of time to allow the Board and the other
Members to participate in selecting the forum in which such petition will be filed. 
 (g) No Member shall file a notice of inconsistent
treatment under Code Section 6222(b) with respect to any Company items for any taxable year without first notifying the Board and each other Member. 

(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

  
 47 

 
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. Notwithstanding anything to the contrary in this Agreement, in no event will any MCK Member or any of its Affiliates be required to provide any information relating to, or a copy
of any consolidated, combined, affiliated or unitary tax return that includes McKesson Corporation or any of its Affiliates (other than pro forma information relating only to the Company’s operations). 

(i) Each Member and former Member shall provide the Company with such information (and, if applicable, with certifications as to the filing of
initial and amended tax returns) as the Tax Matters Member reasonably requests, in order to enable the Company (as determined by the Board and subject to Section 7.04(h)) to (i) reduce the amount of any imputed
underpayment under Section 6225 of the Partnership Tax Audit Rules, (ii) determine its eligibility to make, and make, an election under Section 6221(b) of the Partnership Tax Audit Rules, (iii) make an election under
Section 6226(a) of the Partnership Tax Audit Rules, (iv) reasonably attribute to the Members their share of any income, gain, loss, deduction or credit for purposes of Section 6226(a) of the Partnership Tax Audit Rules, or (v) to
comply with, or be eligible to invoke any aspect of, the Partnership Tax Audit Rules in any other respect. The Tax Matters Member shall not make any such elections, or take or fail to take any actions described in the Partnership Tax Audit Rules
without the consent of the Board. 
 ARTICLE 8 

ALLOCATIONS AND DISTRIBUTIONS 

Section 8.01. Allocations. 

(a) Allocation of Profit and Loss. 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, Section 6.03 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. 

(b) Special Allocations. 

(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. 

  
 48 

 (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 1.704-1(b)(2)(ii)(d) and shall be interpreted
in a manner consistent therewith. 

  
 49 

 (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 1.704-1(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. 
 (c) Tax Allocations. 

(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

  
 50 

 
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.

 Section 8.02. Distributions. 

(a) Tax Distributions. 

(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. 

  
 51 

 (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. 

  
 52 

 (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;
provided, that the Board may authorize that cash be distributed to Echo (which distribution shall be made without pro rata distributions to the other Members) in exchange for the redemption, repurchase or other acquisition of Units held by
Echo, where the redemption proceeds are to be used by Echo to acquire its outstanding Echo Shares (or other Equity Securities of Echo convertible, exchangeable into, exercisable for Echo Shares) in accordance with
Section 3.03(c); and provided further that, to the extent any distribution is made to the Members, other than the distributions specified in Section 8.02(a), the Board may authorize that an
additional amount be set aside in respect of any Units that would be issued in accordance with Section 3.03(c) in respect of any Unvested Echo Shares (the “Escrow Amounts”) to be distributed to Echo (which
distribution shall be made without pro rata distribution to the other Members) at the time such Equity Security of Echo ceases to be an Unvested Echo Share. To the extent that such Unvested Echo Share shall be forfeited by or repurchased from the
holder without having ceased to be an Unvested Echo Share, such Escrowed Amounts corresponding to such forfeited Unvested Escrow Share shall revert to the Company. 

(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) If, at any time after the expiry of the IPO Preference Period and prior to the consummation of a Qualified IPO or a Company Sale,
(i) any Member desires to Transfer any Units to any third party (including through a sale of Echo Shares) or (ii) any of the MCK Members or Echo desires to initiate a sale or auction process to Transfer any Units (or Echo Shares) to a
third party (whether or not such Transfer is a Company Sale) (a “ROFO Sale”, and any such Member, for the purposes of this Section 9.02 and Section 9.03, the

 (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. 

(c) If one or more Significant Members accepts the Initial Offer, but any one or more Significant Members declines (or is deemed to decline)
such Initial Offer, the Offeror shall not be required to sell any Offered Units accepted pursuant to the Initial Offer, but shall, within five (5) Business Days of the expiration of the Initial Offer Period, provide notice to the other
Significant Members (if applicable) that did accept the 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. 

  
 56 

 (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). 

  
 57 

 Section 9.03. Drag-Along Right. 

(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 Initial 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, which shall include, for all purposes of this
Section 9.03, any Equity Securities of Echo convertible, exchangeable into or exercisable for Echo Shares in connection with or upon consummation of such Drag-Along Sale as set forth in
Section 9.03(g)), 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. The Drag-Along Sale Notice shall identify the Drag-Along Transferee, the consideration proposed to be paid in connection with the Drag-Along Sale (the
“Drag-Along Sale Price”) and all other material terms and conditions of the Drag-Along Sale, which shall be no less favorable in the aggregate to the Dragged Members than as set forth in the Initial Offer Notice. The Drag-Along
Sellers will promptly notify the Dragged Members in writing in connection with any change in the material terms and conditions of the Drag-Along Sale; provided, that without complying again with the procedures set forth in
Section 9.02 with respect to any proposed Drag-Along Sale, such modified terms shall be no less favorable in the aggregate to the Dragged Members (or more favorable to the Drag-Along Sellers) then the terms set forth in the
Initial Offer Notice. 
 (c) The Dragged Members shall be required to participate in the Drag-Along Sale on the same terms and conditions as
the Drag-Along Sellers as set forth in the Drag-Along Sale Notice by entering into the agreement(s) governing the terms and conditions of such Drag-Along Sale (the terms and conditions of which shall be consistent with those provided in such
Drag-Along Sale Notice as may be modified from time to time with notice as provided herein); provided, that (i) the Dragged Members shall not be required to agree to any non-compete, non-solicit, no hire or similar post-closing covenant that restricts the Dragged Members’ business and operations (but 

  
 58 

 
shall, for the avoidance of doubt, be required to agree to customary confidentiality and further assurances covenants that do not restrict the Dragged Members’ business or operations in any
material respect), (ii) the Dragged Members’ indemnification obligations in respect of the Company’s representations and warranties shall be (A) joint and several with each other and the Drag-Along Sellers, and
(B) pro rata based on such Dragged Member’s Membership Percentage, (iii) the Dragged Members shall be required to bear their pro rata share (based on the aggregate consideration received in respect of the
Units (or Unit equivalents based on the Echo Ratio) Transferred by such Member) of any escrow, holdback or adjustment in purchase price and any reasonable out-of-pocket
transaction expenses incurred in connection with the Drag-Along Sale (provided, that the Dragged Members and the Company shall only be required to bear the reasonable expenses of one counsel for the Dragged Members), to the extent such
expenses are incurred for the benefit of the Members participating in the Drag-Along Sale, and are not otherwise paid by the Company or the purchaser and the Drag-Along Sale is consummated; (iv) (A) Dragged Members will be required to make
individual representations, warranties, covenants and other agreements as to the unencumbered title to its Units (or Echo Shares) and the power, authority and legal right to Transfer such Units (or Echo Shares) and the absence of any adverse claim
with respect to such Units and (B) be liable as to such representations, warranties, covenants and other agreements; (v) Echo shall not be required to participate in such Drag-Along Sale if such transaction involves, or could reasonably be
expected to be treated in whole or in part for U.S. federal income tax purposes as, a disposition by Echo of any of its Equity Securities in the Company and (vi) Echo, on behalf of the Echo Shareholders, may substitute all of the Echo Shares in
lieu of Units as described in Section 9.03(a); provided further that, no Dragged Member’s liability in connection with a Drag-Along Sale may exceed the proceeds payable to such Dragged Member in the Drag-Along
Sale. 
 (d) In a Drag-Along Sale, the Dragged Members shall be required to tender their Units (or Echo Shares) as set forth below. The price
payable in a Drag-Along Sale shall be the Drag-Along Sale Price. 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. 
 (e) Within one Business Day
following the consummation of a Drag-Along Sale, the Drag-Along Sellers shall give notice thereof to the Dragged Members and shall furnish such other evidence of the completion and time of completion of such Transfer and the terms thereof as may be
reasonably requested by such Dragged Member. In addition, within one Business Day following 

  
 59 

 
the consummation of a Drag-Along Sale, the Drag-Along Sellers shall remit to each Dragged Member the total consideration (any cash portion of which is to be paid by wire transfer in accordance
with each Dragged Member’s wire transfer instructions) for the Units (or Echo Shares) of such Dragged Member Transferred pursuant hereto. 

(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) In the event of any Drag-Along Sale, each holder of Equity Securities of Echo will be deemed to have exercised, converted or exchanged any
vested and exercisable options, warrants or convertible securities immediately prior to the consummation of the Drag-Along Sale to the extent necessary to sell Echo Shares to the Drag-Along Buyer (the “Drag-Along Buyer”), except to
the extent permitted under the terms of any such option, warrant or convertible security and agreed to by the Drag-Along Buyer. All Units issuable upon such exercise, conversion or exchange pursuant to Section 3.03(c) will
be deemed issued and shall be included as “Echo Shares” for all purposes of this Section 9.03. In the event that options, warrants or convertible securities are deemed exercised pursuant to the preceding sentence,
payment of any purchase or exercise price, if applicable, and minimum statutory withholding tax amount, if any, shall be satisfied through payment of Echo Shares otherwise deliverable upon such exercise, conversion, or exchange. If any holder of
Equity Securities of Echo sells options, warrants or convertible securities in any Drag-Along Sale, such holder of Equity Securities of Echo shall receive in exchange for such options, warrants or convertible securities consideration equal to the
amount (if greater than zero) determined by multiplying (a) the same purchase price per share for Echo Shares as those Units sold to the Drag-Along Buyer and specified in the Drag-Along Sale Notice in such Transfer less the exercise, exchange
or conversion price, if any, per share of such option, warrant or convertible security by (b) the number of Echo Shares issuable upon exercise, conversion or exchange of such option, warrant or convertible security (to the extent exercisable,
convertible or exchangeable at the time of such Transfer), subject to reduction for any tax or other amounts required to be withheld under applicable law. 

(h) 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, Section 6.03 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 (subject to
Section 9.03(g)) 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. 

  
 60 

 Section 9.05. Valuation of Units. 

(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 Shareholders are 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 15th 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 

  
 61 

 
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. 

Section 9.06. Additional Members. 

(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”). 
 (b) Each Person who is issued new Units or other Equity Securities of the
Company in accordance with the terms of this Agreement and who is not already a Member shall 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
(including the restrictions on Transfer contained in this Article 9), and shall thereupon be admitted as 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. 

  
 62 

 (f) The Company shall maintain books for the purpose of registering the Transfer of Units.
Upon a Transfer of any record ownership of Units, the Transferor thereof shall notify the Company so that such Transfer may be registered in the books of the Company. 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. 

ARTICLE 10 
 EXIT
PROVISIONS 
 Section 10.01. Qualified IPO. 

(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. As promptly as practicable after its formation, but
in no event later than six (6) months after Closing, the IPO Committee shall appoint one or more nationally recognized investment banks to act as underwriters of the 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

  
 63 

 
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. Notwithstanding anything to the contrary contained herein, in the event of an IPO Demand, the Company shall cause the Board to appoint to the IPO Committee
one additional Director designated by the IPO Demanding Party. 

  
 64 

 Section 10.02. Up-C Structure. Any
Qualified IPO, unless the MCK Members and Echo shall mutually elect otherwise, shall be effected as an initial public offering through Echo. In connection with the consummation of a Qualified IPO, the number of outstanding Echo Shares and Units
shall be adjusted as set forth in Section 3.03(c) to the extent necessary to cause (x) the Echo Ratio is maintained at one Unit to one Echo Share and (y) each of the number of 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 such adjustments. 

Section 10.03. Post-IPO Exit Rights. 

(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 Shareholders 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. 

(b) (i) In order for the Echo Shareholders to exercise the Echo Shareholder Sale Right in respect of the First Echo Sale Window, the
Sponsor Shareholders shall, and, (ii) in order for the Echo Shareholders to exercise the Echo Shareholder Sale Right in respect of the Second Echo Sale Window, the Echo Shareholders entitled to exercise registration rights pursuant to a Holder
Demand (as defined in the Registration Rights Agreement) shall, in each case deliver a written notice to Echo, the MCK Members and the Company (the “Echo Shareholder Notice”) no later than the expiration of the lockup period related
to a Qualified IPO, in the case of the First Echo Sale Window, or within thirty (30) days following expiration or termination of the MCK Exit Window in which a Qualified MCK Exit does not occur, in the case of the Second Echo Sale Window (each,
an “Echo Sale Notice Deadline”), which written notice shall: (i) confirm the intention of the Sponsor Shareholders or Echo Shareholders, as applicable, to conduct and consummate a Qualified Echo Sale in accordance with the Echo
Shareholders Agreement and the Registration Rights Agreement and undertake to provide prompt notice of a change in such intention and to otherwise keep the Company and the MCK Members reasonably updated with respect to the status and other material

[Reserved] 
 Section 10.05. Qualified MCK Exit Process. 

(a) During the MCK Exit Window, the MCK Members and their Affiliates shall have the right to consummate the following series of corporate
actions (each such series upon the consummation of the Merger, the “Qualified MCK Exit”): (i) the formation by MCK of a new Delaware corporation (“SpinCo”) to hold all of the shares of the MCK Members (unless such
corporation has been formed prior to such date) pursuant to a Separation Agreement substantially in the form of Exhibit C attached hereto (the “Separation Agreement”), (ii) (A) the commencement by MCK of one or more
exchange offers pursuant to which MCK will exchange stock of SpinCo for stock of MCK held by the stockholders of MCK (the “Exchange Offers”), (B) the distribution of the stock of SpinCo to the shareholders of MCK as a dividend in
kind (the “Spin-Off”), (C) one or more exchanges of the stock of SpinCo for debt securities of MCK (the “Non-Stock Exchanges”);
provided, that, without the consent of Echo, MCK shall not conduct Non-Stock Exchanges or private exchanges of capital stock (exchanges of securities that do not require registration under the Exchange
Act) with any Person that MCK knows or has reason to believe will be a holder of 5% or more of MCK’s common stock or the Echo Shares immediately after consummation of such Non-Stock Exchanges 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 December 20, 2016 by and between SpinCo and Echo (as such may be amended or supplemented 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. 

(b) In connection with a Qualified MCK Exit, the parties shall cooperate with each other to consummate such Qualified MCK Exit as promptly as
reasonably practicable, including commencing the Exchange Offers pursuant to applicable securities laws, amending the Merger Agreement to the extent required or advisable pursuant to applicable Law, calling any applicable meeting of Echo’s
stockholders to approve the Merger, obtaining any vote required in connection 

  
 66 

 
with the Merger or Qualified MCK Exit required by the board of directors of Echo, preparing and filing any applicable proxy statement and/or registration statement with the SEC in relation to the
Merger, and generally do, execute and perform all such other acts, deeds and documents as may be reasonably required to carry out the Qualified MCK Exit. 

(c) Pursuant to the Echo Shareholders Agreement, the Echo Shareholders will vote all Echo Shares that they are entitled to vote to approve the
issuance of Echo Shares pursuant to the Merger and/or approval of the Merger at any meeting of the stockholders of Echo, and at any adjournment thereof, at which the issuance of Echo Shares and/or approval of the Merger is submitted for the
consideration and vote of the stockholders of Echo. 
 (d) In connection with the consummation of the transactions contemplated in
Section 10.05(a)(ii), each of MCK, Echo, the Company, Change Healthcare Holdings, LLC and SpinCo shall enter into a tax matters agreement substantially in the form attached hereto as Exhibit E (the “Tax
Matters Agreement”) and the Separation Agreement substantially in the form attached hereto as Exhibit C hereto. 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 MCK 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. 

Section 10.06. MCK Top-up Option. 

(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  

  
 67 

 
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 would 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 9.04, without interest. The purchase price must be paid by MCK (or its Affiliate) in cash. 

(c) In the event MCK (or its Affiliates) wishes to exercise the Top-up Option, it shall deliver to the
Company a notice (the “Top-up Notice”) setting forth (i) the number of Top-up Units that it intends to purchase pursuant to the Top-up Option and (ii) the place and time at which the closing of the purchase of such Top-up Units shall occur, which shall be no later than the effective time of the
Merger. 
 (d) At the closing of the purchase of the Top-up Units, MCK or an Affiliate shall cause to
be delivered to the Company the cash consideration required to be delivered in exchange for the Top-up Units, and the Company shall cause to be issued to MCK or such Affiliate a certificate representing the Top-up Units. 
 (e) Notwithstanding the foregoing, at any time during the MCK Exit Window, MCK, on the one
hand, and Echo, on the other hand, may mutually agree to structure the Top-up Option to provide for all, or part, of the exercise of the Top-up Option through a Transfer
of Units held by Echo to MCK, or any of its Affiliates designated by MCK; provided that the parties will mutually agree on a procedure for ensuring that the Echo Ratio is maintained at one Unit to one Echo Share. 

Section 10.07. Registration Rights. The MCK Members and Echo (and certain holders of equity in such Members), shall have the
registration rights set forth in, and the Company shall be subject to the requirements set forth in, Exhibit B hereto (the “Registration Rights Agreement”), which Exhibit B is an integral part of this Agreement. 

Section 10.08. Exit Events Expenses. Subject to the Registration Rights Agreement, each of the Company, MCK, the MCK Members,
Echo, and the Echo Shareholders shall bear their own costs and expenses in connection with any Qualified IPO, Qualified MCK Exit or Qualified Echo Sale; provided, that (i) the Company will bear all customary expenses relating to any
registration of securities in connection with any Qualified IPO, Qualified Echo Sale or Qualified MCK Exit, and (ii) the Company will bear all expenses of the underwriters and/or other advisors in a Qualified IPO (where such Qualified IPO is
structured entirely as a primary issuance of securities).

 (f) Exchanges of Units. 

(i) The MCK Members and their Permitted Transferees shall be entitled at any time and from time to time following a Qualified
IPO and upon the terms and subject to the conditions of this Agreement, to surrender Units to Echo in exchange (each such exchange, an “Exchange”) for the delivery by Echo to such Member(s) of a number of Echo Shares that is equal to the
number of Units requested to be Exchanged. Echo shall at all times cause a number of authorized Echo Shares to be authorized and held in reserve as will be sufficient to comply with any and all requests for Exchange that may be made pursuant to this
Agreement. 
 (ii) The MCK Members shall be entitled to periodic payments from Echo equal to 85% of the tax savings to the
Echo Group (as defined in the Tax Receivable Agreement) arising from the step-up in tax basis resulting from each Exchange. Prior to the first Exchange (if any), Echo and the Exchanging MCK Member shall
negotiate in good faith the terms of a tax receivable agreement to govern the calculation of such payment, with it being understood that the terms of such agreement shall be substantially similar to the terms of the MCK Tax Receivable Agreement;
provided that any such tax savings shall be determined using a “with and without” methodology (treating any deductions attributable to the step-up in tax basis resulting from the Exchanges as
the last items claimed for any taxable year, including after the utilization of any carryforwards). 
 (iii) An MCK Member
may exercise the right to effect an Exchange by delivering a written notice of exchange in respect of the Units to be Exchanged substantially in the form of Exhibit F hereto (the “Notice of Exchange”), duly executed by such Member
or such Member’s duly authorized attorney, to Echo and the Company at the addresses set forth in Section 14.12. 

(iv) A Notice of Exchange from an MCK Member may specify that the Exchange is to be (A) contingent (including as to the
timing) upon the consummation of a purchase by another Person (whether in a tender or exchange offer, an underwritten offering or otherwise) of Echo Shares into which the Units are exchangeable, or contingent (including as to timing) upon the
closing of an announced merger, consolidation or other transaction or event in which the Echo Shares would be exchanged or converted or become exchangeable for or convertible into cash or other securities or property and/or (B) effective upon a
specified future date. Notwithstanding anything herein to the contrary, an MCK Member may withdraw or amend a Notice of Exchange, in whole or in part, prior to the effectiveness of the Exchange, at any time prior to 5:00 p.m. New York City time, on
the Business Day immediately preceding the Exchange date (or any such later time as may be required by applicable Law) by delivery of a written notice of withdrawal to Echo and the Company, specifying (1) the number of withdrawn Units,
(2) if any, the number of Units as to which the Notice of Exchange remains in effect and (3) if the MCK Member so determines, a new Exchange date or any other new or revised information permitted in the Notice of Exchange. 

(v) Each Exchange shall be deemed to be effective immediately prior to the close of business on the Exchange date (or, if
applicable, immediately prior to the completion of the offering, tender or exchange offer or other transaction in connection with which the Exchange is made contingent), and the Exchanging holder shall be deemed to be a holder of Echo Shares from
and after the effectiveness of the Exchange. Within three (3) Business Days of the Exchange date, Echo shall deliver or cause to be delivered to the 

  
 75 

 
Exchanging holder the number of Echo Shares deliverable upon such Exchange, registered in the name of such holder. To the extent the Echo Shares are settled through the facilities of DTC, Echo
will, upon the written instruction of an Exchanging holder, deliver or cause to be delivered the Echo Shares to such holder through the facilities of DTC, to the account of the participant of DTC designated by such holder. 

(vi) If (i) any Echo Shares Exchanged hereunder may be sold pursuant to a registration statement that has been declared
effective by the SEC, (ii) all of the applicable conditions of Rule 144 are met, or (iii) a restrictive legend (or a portion thereof) otherwise ceases to be applicable, Echo, upon the written request of the Exchanging holder thereof shall
promptly provide such holder or its respective transferees, without any expense to such Persons (other than applicable transfer taxes and similar governmental charges, if any) with new certificates (or evidence of book-entry shares) for securities
of like tenor not bearing the provisions of the legend with respect to which the restriction has terminated. In connection therewith, Echo may request, without any expense to Echo, an opinion of counsel to the effect that such legend can be removed,
and such holder shall provide Echo with such information in its possession as Echo may reasonably request in connection with the removal of any such legend. 

(vii) The Company and each Exchanging holder shall bear Echo’s and their own respective expenses in connection with the
consummation of any Exchange by such holder, whether or not any such Exchange is ultimately consummated; provided, however, that Exchanging holder will pay any transfer taxes, stamp taxes or duties, or similar government charges in
connection with, or arising by reason of, any Exchange. 
 (viii) If the Echo Shares are listed on a national securities
exchange, Echo shall use its reasonable best efforts to cause all Echo Shares issued upon an Exchange to be listed on the same national securities exchange upon which the outstanding Echo Shares may be listed or traded at the time of such issuance.

 (ix) When a Unit has been Exchanged in accordance with this Agreement, the Unit shall be deemed transferred from the
Exchanging holder to Echo. 
 (x) No Exchange shall impair the right of the Exchanging holder to receive any distributions
payable on the Units so exchanged in respect of a record date that occurs prior to the date of the Notice of Exchange for such Exchange.

detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company and its consolidated Subsidiaries and (b) devise and maintain a system of internal accounting controls which, in the good faith judgment of the

Subsidiaries’ possession from time to time, and except for any information that is subject to attorney-client privilege or other privilege from disclosure (provided, that to the extent possible, the parties shall cooperate in good faith
to permit disclosure of such information in a manner that preserves such privilege), and, subject, in the case of disputes, to the discovery rules otherwise applicable, the Company agrees to permit any 5% Member (and such Member’s

status as a holder of Units and (ii) any Director, officer, employee, agent supplier, vendor, third party representative or other intermediary of the Company, if such access is requested in order to enable such party to comply with applicable
Law. Any inspection or access right pursuant to this Section 12.02(a) shall take place during regular business hours and the Company and its Subsidiaries shall not be required to cooperate with any inspection or access
requests pursuant to this Section 12.02(a) that would unduly interfere with their business operations.

 ARTICLE 13 

DISSOLUTION, LIQUIDATION AND TERMINATION 

Section 13.01. No Dissolution. The Company shall not be dissolved by the withdrawal of any Member (subject to
Section 13.02(d)) or the admission of Additional Members in accordance with the terms of this Agreement. 

Section 13.02. Events Causing Dissolution. The Company shall be dissolved and its affairs shall be wound up solely upon the first
to occur of the following events: 
 (a) the unanimous determination of the Board to dissolve and terminate the Company (subject to
Section 5.05); 
 (b) the sale of all or substantially all of the Company’s assets; 

(c) the entry of a decree of judicial dissolution of the Company under Section 18-802 of the Act;
or 
 (d) at any time when there are no Members, unless the Company is continued in accordance with the Act. 

Section 13.03. Bankruptcy of a Member. The bankruptcy (including within the meaning of Sections
18-101 and 18-304 of the Act) of a Member shall cause such Member to cease to be a Member, but notwithstanding the occurrence of such event, the Company shall continue
without dissolution. The receivership or dissolution of a Member shall not in and of itself cause the dissolution of the Company, and notwithstanding the occurrence of such event, the Company shall continue without dissolution under the management
and control of the remaining Members, unless there are no remaining Members of the Company. 
 Section 13.04. Winding Up. 

(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. 

  
 79 

 (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 18203 of the Act. 

Section 13.05. Distribution of Assets. 

(a) Except as otherwise provided in Section 13.06, as soon as practicable upon dissolution of the Company, the assets
of the Company (or liquidation proceeds) shall be distributed in the following manner and order of priority (and ratably within each level of priority): 

(i) first, to creditors of the Company; and 

(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. 
 Section 13.06. Distribution of Patents. 

(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. 

  
 80 

 (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.

 (c) Notwithstanding Sections Section 14.02(a) and 14.02(b), the Board may, subject to

Section 14.03. Waiver; Cumulative Remedies. 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. Except as specifically provided herein, the failure or delay of any Member to enforce at any time any of the provisions of this Agreement shall in no way be construed
to be 

  
 82 

 
a waiver of any such provision, nor in any way to affect the validity of this Agreement or any part hereof or the right of any Member thereafter to enforce each and every such provision. No
waiver of any breach of or noncompliance with this Agreement shall be held to be a waiver of any other or subsequent breach or non-compliance. Except as specifically provided herein, all remedies, either under
this Agreement or by Law or otherwise afforded, will be cumulative and not alternative. 
 Section 14.04. Entire Agreement. This
Agreement, the Contribution Agreement, and the other Transaction Documents constitute the entire agreement between the parties hereto with respect to the subject matter hereof and thereof and supersede and cancel all prior agreements,
understandings, representations and warranties, both oral and written, between the parties hereto with respect thereto, and there are no agreements, undertakings, representations or warranties of any of the parties hereto with respect to the
transactions contemplated hereby and thereby other than those set forth herein or therein or made hereunder or thereunder. 

Section 14.05. Third-Party Beneficiaries. Nothing in this Agreement, express or implied, is intended to confer, nor shall anything
herein confer, on any Person other than the parties hereto, and their respective successors or permitted assigns, any rights, remedies, obligations or liabilities, except that any Person who is entitled to exculpation, indemnification or advancement
pursuant to Section 6.01 and is not party to this Agreement shall be an express third-party beneficiary of this Agreement to the extent required for purposes of Section 6.01; provided, that
all claims for indemnification shall be made only in the name and on behalf of such Person by a Member; and provided further that the Sponsor Shareholders shall be an express third party beneficiary with respect to its rights hereunder.

Section 14.07. Severability. Every provision of this Agreement is intended to be severable. If any term or provision hereof is
declared or held illegal or invalid, in whole or in part, for any reason whatsoever, such illegality or invalidity shall not affect the validity or enforceability of the remainder of the Agreement, and such provision shall be deemed amended or
modified to the extent, but only to the extent, necessary to cure such illegality or invalidity. Upon such determination of illegality or invalidity, the parties hereto shall negotiate in good faith to amend this Agreement to effect the original
intent of the parties. In any event, the invalidity or unenforceability of any provision of this Agreement in any jurisdiction shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or
enforceability of this Agreement, including that provision, in any other competent jurisdiction. 

  
 83 

 Section 14.08. Injunctive Relief The parties hereto hereby acknowledge and agree
that a violation of any of the terms of this Agreement will cause the other parties and the Company irreparable injury for which an adequate remedy at law is not available. Accordingly, the parties hereto expressly agree that in addition to any
other remedy that each of the parties and the Company may be entitled to in law or in equity, each of the parties hereto and the Company shall, except as specifically provided otherwise in this Agreement, be entitled to specific performance of the
terms of this Agreement and any injunction, restraining order or other equitable relief that may be necessary to prevent any breach(es) thereof. 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 ANY CHOICE OF LAW PROVISIONS THAT WOULD RESULT IN THE APPLICATION OF THE LAWS OF

 Section 14.10. Dispute Resolution. 

(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 consents and submits, to the fullest extent permitted by Law, to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (or if unavailable, any federal court
sifting in the State of Delaware or, if unavailable, the Delaware Superior Court) and the appellate courts having jurisdiction of appeals in such courts, and each party irrevocably and unconditionally waives, to the fullest extent permitted by Law,
and agrees not to plead, claim or assert, any objection to the exercise of jurisdiction over any suit, action or other proceeding arising out of or relating to this Agreement by the Court of Chancery of the State of Delaware (or if unavailable, by
any federal court sifting in the State of Delaware or, if unavailable, the Delaware Superior Court). For the purposes of any suit, action or other proceeding arising out of or relating to this Agreement, each party irrevocably and unconditionally
waives, to the fullest extent permitted by Law, and agrees not to plead, claim or assert, any objection to the laying of venue in the Court of Chancery of the State of Delaware (or if unavailable, any federal court sifting in the State of Delaware
or, if unavailable, the Delaware Superior Court), and hereby further irrevocably and unconditionally waives, to the fullest extent permitted by Law, and agrees not to plead, claim or assert in any such court that any such action, suit or proceeding
brought in any such court has been brought in an inconvenient forum. Each party irrevocably consents, to the fullest extent permitted by Law, to service of process in connection with any suit, action or other proceeding arising out of or relating to
this Agreement by registered mail to such party at its address set forth in this Agreement, in accordance with the provisions of Section 14.12, and each party hereby designates such person as the party’s agent for
service of process. The consent to jurisdiction set forth in this Section 14.10 shall not constitute a consent to general jurisdiction in the State of Delaware and shall not constitute consent to service of process for any
purpose except as provided in this Section 14.10. The parties hereto agree that a final, non-appealable 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. 

  
 84 

 (b) At any time prior to a Qualified MCK Exit, any dispute arising out of or relating to
this Agreement shall first be submitted to the Ad Hoc Committee that will be formed upon notice by the party wishing to resolve the dispute. The Ad Hoc Committee shall meet (in person, by telephone or by audio-visual conference) within five
(5) Business Days after receipt of notice from the party wishing to resolve the dispute and shall have thirty (30) days to resolve such matters. If such dispute is not fully and finally settled in accordance with the provisions of this
Section 14.10(b) at the conclusion of such 30-day period, then the provisions of Section 14.10(a) shall apply. During such
30-day period only, neither party will commence, pursue or continue any legal proceeding based upon, arising out of or relating to such dispute; provided, however, that during such 30-day period, either party may commence and pursue a legal proceeding in the Delaware Court of Chancery seeking injunctive or other equitable relief under circumstances in which such party will be irreparably
harmed if such party is not able to commence and pursue such legal proceeding during such 30-day period. 

Section 14.11. Waiver of Jury Trial. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE PARTIES HERETO HEREBY
KNOWINGLY AND VOLUNTARILY WAIVES AND AGREES NOT TO ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE) ANY RIGHT TO TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTERS WITH RESPECT TO THIS AGREEMENT OR ANY ALL
ACTIONS OR PROCEEDINGS (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY OR THE RELATIONSHIP ESTABLISHED HEREUNDER. A COPY OF THIS
PARAGRAPH MAY BE FILED WITH ANY COURT AS WRITTEN EVIDENCE OF THE KNOWING, VOLUNTARY AND BARGAINED-FOR AGREEMENT IRREVOCABLY TO WAIVE THE RIGHT TO TRIAL BY JURY IN ANY SUCH ACTION AND THAT SUCH ACTION WILL
INSTEAD BY TRIED BY A JUDGE SITTING WITHOUT A JURY.

Section 2. Registration Under Securities Act. 

2.1. Registration on Demand. 

(a) Demand. Subject to the provisions of this Agreement and the LLC Agreement, at any time and from time to time during an Exercise
Window, one or more Holders shall have the right to require Echo to effect the registration under the Securities Act of all or part of the Registrable Securities held by such Holders, including by means 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 

  
 4 

 
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 reevaluate 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. 
 (b) Limitations on the Holders
During Specified Periods; Tag-Along Rights. 
 (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 (as defined below)), (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 

  
 5 

 
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. 

  
 6 

 (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 2.1, including all expenses of the delivery of all documents required under Section 2.4(a)(vi). 

(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 

  
 7 

 
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 Tagging 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 

  
 8 

 
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. 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 Portion 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 defined below), as applicable, is delivered), then all of the Registrable Securities owned by the H&F Holders and (B) the
Tag-Along Portion of each other Tagging Seller will equal the greater of (x) the Tag-Along Portion of such Tagging Seller determined without

  
 9 

 
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 Portion 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 Portion 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.

 2.2. Incidental Registration. 

(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. 

  
 11 

 (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). 
 (e) Selection of Underwriters. The
underwriters of each underwritten offering of the Registrable Securities pursuant to this Section 2.2 shall be selected by a Board Resolution. 

2.3. Exchanges of Units. Immediately prior to the consummation of any sale by an MCK Member (or its Permitted Transferees) of shares of
Common Stock in an offering registered pursuant to Section 2.1 or Section 2.2, Echo shall issue to such MCK Member (or its Permitted Transferee) a number of shares of Common Stock equal to the number of Units to be exchanged and sold in
such offering by such MCK Member (or its Permitted Transferee) in accordance with the Exchange procedures set forth in Section 11.04(f) of the LLC Agreement. 

2.4. Registration Procedures. 

(a) If and whenever Echo is required to effect a registration or offering of any Registrable Securities under the Securities Act pursuant to
either Section 2.1 or Section 2.2 hereof (including without limitation any offering pursuant to Section 2.1(j) or 2.2(a) hereof), Echo shall, and shall cause the Company as necessary, as expeditiously as possible, to: 

(i) prepare and file with the SEC as soon as practicable a registration statement on an appropriate registration form of the
SEC for the disposition of such Registrable Securities in accordance with the intended method of disposition thereof, which registration statement shall comply as to form in all material respects with the requirements of the applicable form and
include all financial statements required by the SEC to be filed therewith, and thereafter use its reasonable best efforts to cause such registration statement to become effective as soon thereafter as reasonably possible and in any event within 60
days and remain effective (A) with respect to an underwritten offering, for a period of at least 180 days or until all equity interests subject to such registration statement have been sold, and (B) with respect to a shelf registration,
until the earlier of (1) the sale of all Registrable Securities thereunder and (2) the third anniversary of the effective date of such shelf registration; 

  
 12 

 (ii) prepare and file with the SEC any amendments and supplements to such
registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all Registrable
Securities covered by such registration statement in accordance with the intended methods of disposition by the Participating Holders set forth in such registration statement for such period as provided for in Section 2.4(a)(i) above; 

(iii) furnish, without charge, to each Participating Holder and each underwriter such number of conformed copies of such
registration statement and of each such amendment and supplement thereto (in each case including all exhibits), such number of copies of the prospectus contained in such registration statement (including each preliminary prospectus and summary
prospectus) and any other prospectus filed under Rule 424 under the Securities Act, in conformity with the requirements of the Securities Act, and such other documents, as the Participating Holders and such underwriters may request (it being
understood that Echo consents to the use of such prospectus or any amendment or supplement thereto by each Participating Holder and the underwriters in connection with the offering and sale of the Registrable Securities covered by such prospectus or
any amendment or supplement thereto); 
 (iv) use its reasonable best efforts (A) to register or qualify all Registrable
Securities and other securities covered by such registration statement under such foreign or state securities or “blue sky” laws where an exemption is not available and as the Participating Holders or any managing underwriter shall
request, (B) to keep such registration or qualification in effect for so long as such registration statement remains in effect, and (C) to take any and all other actions which may be necessary or advisable to enable the Participating
Holders or underwriters to consummate the disposition in such jurisdictions of the securities to be sold by the Participating Holders or Echo, except that Echo shall not for any such purpose be required to qualify generally to do business as a
foreign company in any jurisdiction wherein it would not, but for the requirements of this Section 2.4(a)(iv), be obligated to be so qualified; 

(v) use its reasonable best efforts to cause all Registrable 

Securities covered by such registration statement to be registered with or approved by such other governmental agencies or
authorities as may be necessary in the opinion of counsel to Echo and counsel to the Participating Holders to consummate the disposition of such Registrable Securities; 

(vi) furnish to each Participating Holder and each underwriter a signed counterpart of (A) an opinion of one or more
counsel (including local counsel, if applicable) for Echo, (B) a “comfort” letter signed by the independent public accountants who have certified Echo’s or any acquired entity’s or any other financial statements included or
incorporated by reference in such registration statement, in each case, addressed to each Participating Holder and each underwriter covering matters with respect to such registration statement (and the prospectus included therein) as the
Participating Holders and managing underwriter(s) shall request and (C) if requested by the managing underwriter(s), a certificate executed by the Chief Financial Officer or the Chief 

  
 13 

 
Accounting Officer of Echo attesting to the material accuracy of any financial information not “comforted” by such independent public accountants; provided that, with respect to
(B) above, if such accountants are prohibited from addressing such letters to a Participating Holder by applicable standards of the accounting profession, Echo shall cause an “agreed-upon procedures” letter to be furnished; 

(vii) promptly notify each Participating Holder and each managing underwriter (A) when such registration statement, any pre-effective amendment, the prospectus or any prospectus supplement related thereto or post-effective amendment to such registration statement has been filed, and, with respect to such registration statement or any
post-effective amendment, when the same has become effective; (B) of the receipt by Echo of any comments from the SEC or receipt of any request by the SEC for additional information with respect to any registration statement or the prospectus
related thereto or any request by the SEC for amending or supplementing the registration statement and the prospectus used in connection therewith; (C) of the issuance by the SEC of any stop order suspending the effectiveness of such
registration statement or the initiation of any proceedings for that purpose; (D) of the receipt by Echo of any notification with respect to the suspension of the qualification of any of the Registrable Securities for sale under the securities
or “blue sky” laws of any jurisdiction or the initiation of any proceeding for such purpose; and (E) at any time when a prospectus relating thereto is required to be delivered under the Securities Act, upon discovery that, or upon the
happening of any event as a result of which, the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to
make the statements therein not misleading, in the light of the circumstances under which they were made, and in the case of this clause (E), promptly prepare and furnish, at the Company’s expense, to each Participating Holder and each managing
underwriter, and file with the SEC, a number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such securities, such prospectus shall not include an untrue
statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; and (F) at any time when the
representations and warranties of Echo or the Company contemplated by Section 2.5(a) or (b) hereof cease to be true and correct; 

(viii) otherwise comply with all applicable rules and regulations of the SEC, and make available to its security holders, as
soon as practicable (and in any event within 16 months after the effective date of the registration statement), an earnings statement covering the period of at least twelve consecutive months beginning with the first full calendar month after the
effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder; 

(ix) provide and cause to be maintained a transfer agent and registrar for all Registrable Securities covered by such
registration statement from and after a date not later than the effective date of such registration statement; 

  
 14 

 (x) (A) use its reasonable best efforts to cause all Registrable
Securities covered by such registration statement to be listed on the principal securities exchange on which shares of Common Stock are then listed (if any), if the listing of such Registrable Securities is then permitted under the rules of such
exchange, or (B) if shares of Common Stock are not then so listed, use its reasonable best efforts to cause all such Registrable Securities to be listed on a national securities exchange in the U.S.; 

(xi) deliver promptly to counsel to the Participating Holders and each underwriter, if any, participating in the offering of
the Registrable Securities, copies of all correspondence between the SEC and Echo, its counsel or auditors and all memoranda relating to discussions with the SEC or its staff with respect to such registration statement; 

(xii) use its reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of the registration
statement; 
 (xiii) provide a CUSIP number for all Registrable Securities, no later than the effective date of the
registration statement, and provide the applicable transfer agents with printed certificates (if required) for the Registrable Securities which are in a form eligible for deposit with The Depository Trust Company; 

(xiv) cause its officers and employees to participate in, and to otherwise facilitate and cooperate with the preparation of the
registration statement and prospectus and any amendments or supplements thereto (including participating in meetings, drafting sessions, due diligence sessions and the marketing of the Registrable Securities covered by the registration statement
(including, without limitation, participation in “road shows”)), taking into account the Company’s business needs and obligations; 

(xv) enter into and perform its obligations under such customary agreements (including, without limitation, customary lock-up agreements for Echo, the Company and the directors and officers of the Company and, if applicable, an underwriting agreement as provided for in Section 2.5 herein) and take such other actions as the
Participating Holders or managing underwriter(s) shall request in order to expedite or facilitate the disposition of such Registrable Securities, including appointing an agent for service of process in the U.S. on customary terms; 

(xvi) promptly incorporate in a prospectus supplement or post-effective amendment such information as the managing
underwriter(s) or Participating Holders request to be included therein relating to the plan of distribution with respect to such Registrable Securities; and make all required filings of such prospectus supplement or post-effective amendment as soon

(xvii) cooperate with each Participating Holder and each underwriter, and their respective counsel, in connection with any
filings or submissions required to be made with FINRA, the New York Stock Exchange, The NASDAQ Stock Market or any other securities exchange on which such Registrable Securities are traded or will be traded; 

  
 15 

 (xviii) include in any prospectus supplement, if requested by any managing
underwriter, updated financial information for Echo’s (and/or the Company’s) most recent or current quarterly period (including estimated results or ranges of results) if required for purposes of marketing the offering in the view of the
managing underwriter; 
 (xix) promptly prior to the filing of any document that is to be incorporated by reference into the
registration statement or the prospectus contained therein (after the initial filing of such registration statement), provide copies of such document to counsel for the Participating Holders and to each managing underwriter, and make Echo’s
representatives available for discussion of such document and make such changes in such document concerning the Participating Holders prior to the filing thereof as counsel for such Participating Holders or underwriters may request; 

(xx) furnish to each Participating Holder and each managing underwriter(s), without charge, at least one signed copy of the
registration statement and any post-effective amendments thereto, including financial statements and schedules, all documents incorporated therein by reference and all exhibits (including those incorporated by reference); 

(xxi) cooperate with the Participating Holders and the managing underwriter(s) to facilitate the timely preparation and
delivery of certificates not bearing any restrictive legends representing the Registrable Securities to be sold, and cause such Registrable Securities to be issued in such denominations and registered in such names in accordance with the
underwriting agreement prior to any sale of Registrable Securities to the underwriters or, if not an underwritten offering, in accordance with the instructions of the Participating Holders at least five business days prior to any sale of Registrable
Securities, and instruct any transfer agent or registrar of Registrable Securities to release any stop transfer orders in respect thereof; 

(xxii) to the extent required by the rules and regulations of FINRA, retain a Qualified Independent Underwriter (as defined by
FINRA), which shall be acceptable to the Majority Participating Holders; and 
 (xxiii) take no direct or indirect action
prohibited by Regulation M under the Exchange Act; provided, however, that to the extent that any prohibition is applicable to Echo, Echo will take such action as is necessary to make any such prohibition inapplicable. 

(b) If and whenever Echo is required to effect a registration or offering of any Registrable Securities under the Securities Act pursuant to
either Section 2.1 or Section 2.2 hereof (including without limitation any offering pursuant to Section 2.1(j) or 2.2(a) hereof), the Company shall as expeditiously as possible: 

(i) cooperate with Echo to prepare any financial statements of the Company or any other entity required by the Securities Act
to be included in the registration statement relating to the offer of such Registrable Securities; and 

  
 16 

 (ii) use its reasonable best efforts to take any and all other actions
reasonably requested by Echo which may be necessary or advisable to enable the Participating Holders or underwriters to consummate the disposition in such jurisdictions of the securities to be sold by the Participating Holders or Echo, except that
the Company shall not for any such purpose be required to qualify generally to do business as a foreign company in any jurisdiction wherein it would not, but for the requirements of this Section 2.4(b)(ii), be obligated to be so qualified. 

(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. If the disposition by a Participating Holder of its securities is discontinued pursuant to the foregoing
sentence, Echo shall extend the period of effectiveness of the registration statement by the number of days during the period from and including the date of the giving of such notice to and including the date when the Participating Holder shall have
received copies of the supplemented or amended prospectus contemplated by Section 2.4(a)(vii)(E). If for any other reason the effectiveness of any registration statement filed pursuant to Section 2.1 or Section 2.2 is suspended or
interrupted prior to the expiration of the time period regarding the maintenance of the effectiveness of such Registration Statement required by Section 2.4(a)(i) so that Registrable Securities may not be sold pursuant thereto, the applicable
time period shall be extended by the number of days equal to the number of days during the period beginning with the date of such suspension or interruption to and ending with the date when the sale of Registrable Securities pursuant to such
registration statement may be resumed. 
 (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. 
 2.5.
Underwritten Offerings. 
 (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 

  
 17 

 
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. Echo shall not be obligated to effect the registration of any Registrable Securities of a particular Participating Holder unless such information and documents regarding such Participating Holder and the
distribution of such Participating Holder’s Registrable Securities is provided to Echo. 

  
 18 

 2.6. Preparation; Reasonable Investigation. In connection with the preparation and
filing of each registration statement, prospectus and prospectus supplement under the Securities Act pursuant to this Agreement, Echo (and the Company, as applicable) will give the Participating Holders, the managing underwriter(s), and their
respective counsel, accountants and other representatives and agents the opportunity to participate in the preparation of such registration statement, each prospectus included therein or filed with the SEC, and each amendment thereof or supplement
thereto or comparable statements under securities or “blue sky” laws of any jurisdiction, and give each of the foregoing parties access to its books and records, all financial and other records, pertinent corporate documents and properties
of Echo and the Company and their respective subsidiaries, and such opportunities to discuss the business of the Company and Echo and their respective subsidiaries with their respective directors, officers and employees and the independent public
accountants who have certified the Company’s and/or Echo’s financial statements, and supply all other information and respond to all inquiries requested by such Participating Holders, managing underwriter(s), or their respective counsel,
accountants or other representatives or agents in connection with such registration statement, prospectus and prospectus supplement as shall be necessary or appropriate, in the opinion of counsel to such Participating Holder or managing
underwriter(s), to conduct a reasonable investigation within the meaning of the Securities Act, and Echo shall not file any registration statement or amendment thereto or any prospectus or supplement thereto to which the Participating Holders or the
managing underwriter(s) shall object. 
 2.7. Indemnification. 

(a) Indemnification by the Company. The Company agrees that in the event of any registration or offering of any Registrable Securities
under the Securities Act, the Company shall, and hereby does, indemnify and hold harmless, to the fullest extent permitted by law, (i) each of Echo, the Holders and their respective Affiliates, (ii) each of the Holders’ and their
Affiliates’ respective direct and indirect officers, directors, successors, assigns, members, partners, shareholders, employees, advisors, representatives and agents, (iii) each other Person who participates as an underwriter or Qualified
Independent Underwriter (as defined by FINRA) in the offering or sale of such securities, (iv) each Person who controls, directly or indirectly (within the meaning of the Securities Act or the Exchange Act), any of the Persons listed in clauses
(i), (ii), (iii) or (iv) and (v) any representative (legal or otherwise) of any of the Persons listed in clauses (i), (ii), (iii) or (iv) (other than the Company) (collectively, the “Company Indemnitees”), from and against any
losses, penalties, fines, liens, judgments, suits, claims, damages, liabilities, costs and expenses (including attorney’s fees and any amounts paid in any settlement effected in compliance with Section 2.7(e)) or liabilities, joint or
several (or actions or proceedings, whether commenced or threatened, in respect thereof, and whether or not such Company Indemnitee is a party thereto) (“Losses”), to which such Company Indemnitee has become or may become subject
under the Securities Act or otherwise, insofar as such Losses arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact regarding the Company or Echo for inclusion in any registration statement
under which such securities were registered under the Securities Act, or any preliminary prospectus or final prospectus contained therein, any amendment or supplement thereto, or any documents incorporated by reference therein, or any

  
 19 

 
related free writing prospectus, (ii) any omission or alleged omission by the Company or Echo to state a material fact regarding the Company or Echo required to be stated therein or
necessary to make the statements therein not misleading, or (iii) any violation by the Company or Echo of any federal, state or common law rule or regulation applicable to the Company or Echo and relating to action required of or inaction by
the Company or Echo in connection with any such registration or offering, and the Company shall reimburse 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. 

  
 20 

 (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. 

  
 21 

 (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. 

  
 22 

 (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. The Company further agrees that no advancement or payment by such other sources on behalf of a Company Indemnitee with respect to any claim for which such Company
Indemnitee has sought indemnification, advancement of expenses or insurance from the Company 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 Company Indemnitee against the Company. 
 2.8. Limitation on Sale of Securities. 

(a) For the Company and Echo and Others. If Echo receives a request for registration pursuant to an underwritten offering of Registrable
Securities, or is notified of an underwritten offering of Registrable Securities, in each case pursuant to Section 2.1 or 2.2 hereof, and if such a request is being implemented or has not been withdrawn or abandoned, Echo agrees that
(i) neither Echo nor the Company shall affect any public or private offer, sale, distribution or other disposition of any of its equity securities or of any security convertible into or exchangeable or exercisable for any equity security or
effect any registration of any of such securities under the Securities Act (in each case, other than (x) equity incentive grants to employees pursuant to equity incentive plans, (y) as part of such registration and (z) as a
registration using Form S-8 or any successor or similar form which is then in effect), whether or not for sale for its own account, during the period beginning on the date Echo and the Company receive such
request until up to 180 days (90 days in any offering following a Qualified IPO) after the date of the prospectus or prospectus supplement related to the underwritten offering (or such shorter period as the managing underwriter(s) may require) and
(ii) Echo shall use its reasonable best efforts (including by enforcing the Echo Shareholders’ Agreement) to 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. 

(b) For the Holders. If Echo receives a request for registration pursuant to an underwritten offering of Registrable Securities, or is
notified of an underwritten offering of Registrable Securities, in each case pursuant to Section 2.1 or 2.2 hereof, and if such a request is being implemented or has not been withdrawn or abandoned, each Holder agrees that, to the extent
requested in writing by the managing underwriter(s), it will not affect any public or private offer, sale, distribution or other disposition of any Registrable Securities, or any securities convertible into or exchangeable or exercisable for such
Registrable Securities, including, without limitation, any sale pursuant to Rule 144 under the Securities Act, during a period of up to 180 days (90 days 

  
 23 

 
in any offering following a Qualified IPO) beginning on the date of the prospectus or prospectus supplement related to the underwritten offering (or such shorter period as the managing
underwriter(s) may require), provided that each Holder has received the written notice required by Sections 2.1(a) and 2.2(a); and provided further, that in connection with such underwritten offering each officer and director of the Company and Echo
is subject to restrictions substantially equivalent to those imposed on 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.
Upon the request of a Holder, Echo will promptly deliver to such Holder (i) a written statement as to whether it has complied with such requirements (and such Holder shall be entitled to rely upon the accuracy of such written statement), (ii) a
copy of the most recent annual or quarterly report of Echo and (iii) such other reports and documents as such Holder may reasonably request in order to avail itself of any rule or regulation of the SEC allowing it to sell any Registrable
Securities without registration. 
 Section 3. Subsequent Registration Rights; No Inconsistent Agreements. 

3.1. Limitations on Subsequent Registration Rights. 

(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. 

  
 24 

 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. 
 Section 4. Miscellaneous. 

4.1. Term. This Agreement shall terminate upon such time as there are no Registrable Securities, provided that each of (a) the
provisions of Section 2.7 and Section 2.10 and all of this Section 4 and (b) any breach of this Agreement prior to termination shall survive any such termination. 

4.2. Injunctive Relief It is hereby agreed and acknowledged that it will be impossible to measure in money the damage that would be
suffered if the parties fail to comply with any of the obligations herein imposed on them and that in the event of any such failure, an aggrieved Person will be irreparably damaged and will not have an adequate remedy at law. Any such Person shall,
therefore, be entitled (in addition to any other remedy to which it may be entitled in law or in equity) to injunctive relief, including specific performance, to enforce such obligations, and if any action should be brought in equity to enforce any
of the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law. 
 4.3.
Notices. Any and all notices, designations, offers, acceptances or other communications provided for herein shall be given (a) when delivered personally by hand (with written confirmation of receipt), (b) when sent by facsimile (with
written confirmation of transmission), (c) when received or rejected by the addressee if sent by registered or certified mail, postage prepaid, return receipt requested, or (d) one Business Day following the day sent by overnight courier (with
written confirmation of receipt):

 4.4. Amendment. Any provision of this Agreement may be amended if, and only if, such
amendment is in writing and signed by both the MCK Members and the Echo Shareholders; provided, that this Section 4.4 may not be amended without the prior written consent of each of the Sponsor Holders and the MCK Members. 

4.5. Successors, Assigns and Transferees. Each party may assign all or a portion of its rights hereunder to any Permitted Transferee
and, prior to a Qualified IPO, to any Person that acquires Registrable Securities pursuant to the terms of the LLC Agreement. 

  
 27 

 4.6. Binding Effect. Except as otherwise provided in this Agreement, the terms and
provisions of this Agreement shall be binding on and inure to the benefit of each of the parties hereto and their respective successors. 

4.7. Third Parties. Nothing in this Agreement, express or implied, is intended or shall be construed to confer upon any Person not a
party hereto (other than each other Person entitled to indemnity or contribution under Section 2.7) any right, remedy or claim under or by virtue of this Agreement. 

4.8. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware applicable to
contracts entered into and performed entirely within such State. 
 4.9. Jurisdiction. Any claim, action, suit or proceeding (whether
in contract or tort) seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby shall be heard and determined in the Chancery Court of the State of
Delaware and any state appellate court therefrom within the State of Delaware (or, if the Chancery Court of the State of Delaware declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware), and
each of the parties hereto hereby consents to the exclusive jurisdiction of such courts (and of the appropriate appellate courts therefrom in any such claim, action, suit or proceeding) and irrevocably waives, to the fullest extent permitted by law,
any objection that it may now or hereafter have to the laying of venue of any such claim, action, suit or proceeding in any such court or that any such claim, action, suit or proceeding that is brought in any such court has been brought in an
inconvenient forum. Notwithstanding the previous sentence, a party may commence any claim, action, suit or proceeding in a court other than the above-named courts solely for the purpose of enforcing an order or judgment issued by one of the
above-named courts. 
 4.10. Waiver of Jury Trial. Subject to applicable Law, process in any such claim, action, suit or proceeding
may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing and subject to applicable Law, each party agrees that service of process on such party as provided in
Section 4.3 shall be deemed effective service of process on such party. Nothing herein shall affect the right of any party to serve legal process in any other manner permitted by Law or at equity. WITH RESPECT TO ANY SUCH CLAIM, ACTION, SUIT OR
PROCEEDING IN ANY SUCH COURT, TO THE EXTENT NO PROHIBITED BY APPLICABLE LAW THAT CANNOT BE WAIVED, EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES AND RELEASES TO EACH OF THE OTHERS ITS RIGHT TO A TRIAL BY JURY, AND AGREES THAT IT WILL NOT SEEK A
TRIAL BY JURY IN ANY SUCH PROCEEDING. EACH PARTY HERETO ACKNOWLEDGES THAT IT HAS BEEN INFORMED BY THE OTHER PARTIES HERETO THAT THIS SECTION 4.10 CONSTITUTES A MATERIAL INDUCEMENT UPON WHICH THEY ARE RELYING AND WILL RELY IN ENTERING INTO THIS
AGREEMENT. ANY PARTY HERETO MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 4.10 WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF EACH SUCH PARTY TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY. 

  
 28 

 4.11. Severability. If any portion of this Agreement shall be declared void or
unenforceable by any court or administrative body of competent jurisdiction, then, so long as no party is deprived of the benefits of this Agreement in any material respect, such portion shall be deemed severable from the remainder of this
Agreement, which shall continue in all respects valid and enforceable. 
 4.12. Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed an original, and all of which shall constitute one and the same agreement. Copies of executed counterparts transmitted by telecopy or other electronic transmission service shall be considered original
executed counterparts for purposes of this Section 4.12. 
 4.13. Construction. The headings and subheadings in this Agreement
are included for convenience and identification only and are in no way intended to describe, interpret, define or limit the scope, extent or intent of this Agreement or any provision hereto. Definitions shall be equally applicable to both the
singular and plural forms of the terms defined, and references to the masculine, feminine or neuter gender shall include each other gender. The word “including” means including without limitation. Any reference to “$” or
“dollars” means United States dollars. References to a particular statute or regulation include all rules and regulations thereunder and any successor statute, rule or regulation, in each case as amended or otherwise modified from time to
time. The parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties and no
presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Agreement. Any action to be taken by or any consent to be given by the “Blackstone Holders”, the
“H&F Holders” or the “MCK Members”, unless otherwise specified herein, are to be taken or consented to upon the approval of the Person(s) holding a majority of the Registrable Securities beneficially owned by such group. 

4.14. Entire Agreement. This Agreement is intended by the parties hereto as a final expression of their agreement and is intended to be
a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. This Agreement supersedes all prior agreements and understandings between the parties hereto with respect
to such subject matter. 
 4.15. The Company Parties. The Company Parties hereby agree that each of the Company Parties will be
jointly and severally liable for any payment obligations of the Company contained in this Agreement.

of March 1, 2017 (as amended or otherwise modified from time to time, the “LLC Agreement”); 
 WHEREAS, pursuant to
the terms of the LLC Agreement, IPCo, PST Services and their Affiliates have determined that it is in the best interests of each such party and their stockholders to consummate the transactions set forth in this Agreement and effect the separation
of SpinCo from Parent by [(i) consummating an offer to exchange 100% of the issued and outstanding shares of SpinCo Common Stock (as defined below) held directly or indirectly by Parent, for consideration as more particularly described under
Section 3.02 below (such transaction, the “Exchange Offer”), and (ii) in the event that holders of outstanding shares of Parent Common Stock (as defined below) subscribe for less than all of the shares of SpinCo Common
Stock owned by Parent in the Exchange Offer, then at the sole election of Parent,] distributing the [remaining] shares of SpinCo Common Stock owned by Parent by means of a pro rata dividend, to holders of Parent Common Stock as of the Record
Date (as defined below) (the [transactions under (ii) if applicable, the “Clean-up Distribution”, and the transactions under (i) and (ii) together, the]

 WHEREAS, Parent has determined that, subject to the terms and conditions here, it would be desirable
for Parent to transfer to SpinCo all of Parent’s direct and indirect equity interest in JV, which may include the transfer of all of the issued and outstanding equity of the MCK Members (as defined in the LLC Agreement), in exchange for
Parent’s receipt of SpinCo Common Stock (such transfer, the “Controlled Transfer”);

WHEREAS, for United States federal income tax purposes, (i) the Controlled Transfer, together with the Distribution, will qualify as a
“reorganization” within the meaning of Section 368(a)(1)(D) of the Internal Revenue Code of 1986, as amended (the “Code”), and that each of Parent and SpinCo will be a “party to the reorganization” within
the meaning of Section 368(b) of the Code, (ii) the Distribution, as such, will qualify as a distribution of SpinCo Common Stock to Parent’s shareholders pursuant to Section 355 of the Code, (iii) the Merger will not cause
Section 355(e) of the Code to apply to the Distribution, (iv) the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code and that each of Acquiror and SpinCo will be a “party to the
reorganization” within the meaning of Section 368(b) of the Code and (v) this Agreement constitutes a “plan of reorganization” within the meaning of Treasury Regulation
Section 1.368-2(g); and WHEREAS, the parties hereto have determined to set forth the principal actions required to effect the Distribution and to set forth certain agreements that will govern the

and other records (including accountant’s work papers, to the extent consents have been obtained), information, employees and auditors to the extent necessary or reasonably useful for such other party’s Group in connection with any audit,
investigation, dispute or litigation, complying with their obligations under this Agreement or any Ancillary Agreement, any regulatory proceeding, any regulatory filings, complying with reporting disclosure requirements or any other requirements

agreement to which such party or member of its Group is a party, or waive any attorney-client privilege applicable to such party or any member of its Group, the parties shall use reasonable efforts to permit the compliance with such request in a

primarily relating to the JV Business in which any member of the Parent Group or any Affiliate of a member of the Parent Group is a defendant or the party against whom the claim or investigation is directed solely as a result of any member of the
Parent Group being a beneficial owner of the JV or any other member of the JV Group (but shall exclude all Actions to the extent relating to contractual obligations of any member of the Parent Group); and (2) from and after the Distribution

between the SpinCo Group or Acquiror Group on one hand and the Parent Group on the other hand, no party shall be required to grant access or disclosure pursuant to this Section 5.02 in respect of such dispute, and any such access and disclosure
in respect of such dispute shall be subject to the applicable discovery rules.

costs and expenses (including attorney’s fees but excluding reimbursement for general overhead, salary and employee benefits) actually incurred in providing such access, information, witnesses or cooperation. 

  
 14 

 (b) All information owned by one party that is provided to the other party under

request in writing prior to the scheduled date for such destruction or disposal that any of the information proposed to be destroyed or disposed of be delivered to the Receiving Party, the Disposing Party shall promptly arrange for the delivery of
such of the information as was requested at the expense of the Receiving Party; provided that in the event that the Disposing Party reasonably determines that any such provision of information would violate any applicable Law or agreement to
which such party or member of its Group is a party, or waive any attorney-client privilege applicable to such party or any member of its Group, the parties shall use reasonable efforts to permit the compliance with such request in a manner that
avoids any such harm or consequence. Any records or documents that were subject to a litigation hold prior to the Distribution Date must be retained by the applicable party until such party is notified by the other party that the litigation hold is

(iv) in the case of any Member, to any Person to whom such Member is contemplating a Transfer of all or any portion of its

or competitively or strategically sensitive information about the W or any of its Subsidiaries to (a) any limited partner that is not subject to customary confidentiality and non-use restrictions with
respect to such information (subject to customary exceptions) or (b) to any other Person in the course of investing or fundraising activities that is not subject to customary confidentiality and non-use
restrictions with respect to such information (subject to customary exceptions) and, in any of either (a) or (b), any non-public financial information shall be limited to Blackstone’s and H&F
‘s or their fund Affiliates’ valuation of the JV and its Subsidiaries without providing underlying forecasted financial data or

Member and the Echo Shareholders (as defined in the LLC Agreement) may incidentally develop or receive from third parties information not known by such recipient to have been obtained in violation of this Agreement that is the same as or similar to

other hand, may possess documents or other information regarding the other Group that is or may be subject to the attorney-client privilege, the work product doctrine or common interest privilege (collectively, “Privileges”; and such
documents and other information collectively, the “Privileged Information”). Each party agrees to use reasonable efforts to protect and maintain, and to cause their respective Affiliates to protect and maintain, any applicable claim
to Privilege in order to prevent any of the other party’s Privileged Information from being disclosed or used in a manner inconsistent with such Privilege without the other party’s consent. Without limiting the generality of the foregoing,
the parties shall not, and shall direct their respective Affiliates not to, without the other party’s prior written consent, (i) waive any Privilege with respect to any of the other party’s Privileged Information, (ii) fail to

external legal counsel currently representing SpinCo Group (each a “Prior Company Counsel”) may serve as counsel to Parent Group and its Affiliates in connection with any matters arising under or related to this Agreement or the
transactions contemplated by this Agreement or any Ancillary Agreement, including with respect to any litigation, Claim or obligation arising out of or related to this Agreement or any Ancillary Agreement or the transactions contemplated by this
Agreement or any Ancillary Agreement, notwithstanding any representation by the Prior Company Counsel prior to the Distribution Effective Time. Parent Group and SpinCo Group hereby irrevocably (i) waive any Claim they have or may have that a
Prior Company Counsel has a conflict of interest or is otherwise prohibited from engaging in such representation and (ii) covenant and agree that, in the event that a dispute arises after the Distribution Effective Time between SpinCo and its
Affiliates, on the one hand, and Parent and its Affiliates, on the other hand, Prior Company Counsel may represent any member of the Parent Group and any Affiliates thereof in such dispute even though the interests of such Person(s) may be directly
adverse to the Parent Group or the SpinCo Group or their respective Affiliates and even though Prior Company Counsel may have represented the SpinCo Group in a matter substantially related to such dispute. 

  
 18 

 (d) For the avoidance of doubt, nothing in this Agreement shall constitute a waiver of, or
obligate any Person to waive, any Privilege.

obligation to close the Merger in accordance with the Merger Agreement. 
 Section 6.03. Parent Indemnification of SpinCo Group.

 (a) Effective at and after the Distribution, Parent shall indemnify, defend and hold harmless the Acquiror Group as successor to the

Agreement or otherwise, any Damages arising from or relating to, directly or indirectly, whether by operation of the provisions of this Agreement, the Tax Matters Agreement, the Merger Agreement or otherwise, any failure of the Merger Effective Time

(b) Parent shall indemnify, defend and hold harmless each of the SpinCo Indemnitees and each Person, if any, who controls any SpinCo Indemnitee
within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all Losses caused by any untrue statement or alleged untrue statement of a material fact contained in any Applicable
SEC Filing (as amended or supplemented), or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each
case to the extent, but only to the extent, that such Losses are caused otherwise than solely by any such untrue statement or omission or alleged untrue statement or omission based on, and in conformity with, information furnished by the Acquiror
solely in respect of the Acquiror Group or the JV Group. 
 Section 6.04. Procedures. 

(a) The party seeking indemnification under Section 6.02 or Section 6.03 (the “Indemnified Party”) agrees to give
prompt notice to the party against whom indemnity is sought (the “Indemnifying Party”) of the assertion of any claim, or the commencement of any suit, action or proceeding (each, a “Claim”) in respect of which
indemnity may be sought hereunder and shall provide the Indemnifying Party such information with respect thereto that the Indemnifying Party may reasonably request. The failure to so notify the Indemnifying Party shall not relieve the Indemnifying
Party of its obligations hereunder, except to the extent such failure shall have prejudiced the Indemnifying Party. 
 (b) The Indemnifying
Party shall be entitled to participate in the defense of any Claim asserted by any Third Party (“Third Party Claim”) and, subject to the limitations set forth in this Section 6.04, if it so notifies the Indemnified Party no
later than 30 days after receipt of the notice described in Section 6.04(a), shall be entitled to control and appoint lead counsel for such defense, in each case at its expense; 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 Losses the Indemnified Party may

  
 21 

 
suffer resulting from, arising out of, relating to, in the nature of, or caused by such Third Party Claim, (ii) such Third Party 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 Third Party Claim and (iv) such Third Party Claim does not relate to or otherwise arise in connection with Taxes or any criminal or regulatory enforcement action. If the Indemnifying Party does not so notify the
Indemnified Party, the Indemnified Party shall have the right to defend or contest such Third Party Claim through counsel chosen by the Indemnified Party that is reasonably acceptable to the Indemnifying Party, subject to the provisions of this
Section 6.04. The Indemnified Party shall provide the Indemnifying Party and such counsel with such information regarding such Third Party Claim as either of them may reasonably request (which request may be general or specific). 

(c) If the Indemnifying Party shall assume the control of the defense of any Third Party Claim in accordance with the provisions of
Section 6.04(b), (i) the Indemnifying Party shall obtain the prior written consent of the Indemnified Party (which shall not be unreasonably withheld) before entering into any settlement of such Third Party Claim, if the settlement does not
release the Indemnified Party from all liabilities and obligations with respect to such Third Party Claim, involves a finding or admission of any violation of applicable Law or rights of any Person or the settlement imposes injunctive or other
equitable relief against the Indemnified Party or any of its related Indemnitees or is otherwise materially prejudicial to any such Person and (ii) the Indemnified Party shall be entitled to participate in (but not control) the defense of such
Third Party Claim and, at its own expense, to employ separate counsel of its choice for such purpose; provided that in the event of a conflict of interest between the Indemnifying Party and the applicable Indemnified Party, the reasonable and
documented fees and expenses of such separate counsel shall be at the Indemnifying Party’s expense. 
 (d) Each party shall reasonably
cooperate, and cause their respective Affiliates to reasonably cooperate, in the defense or prosecution of any Third Party Claim and shall furnish or cause to be furnished such records, information and testimony, and attend such conferences,
discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith. 
 (e) The parties hereby
acknowledge that an Indemnified Party may have certain rights to indemnification, advancement of expenses and/or insurance provided by other sources. Each Indemnifying Party hereby agrees (i) that it is the indemnitor of first resort (i.e., its
obligations to an Indemnified Party are primary and any obligation of such other sources to advance expenses or to provide indemnification or insurance for the same expenses or liabilities incurred by such Indemnified Party are secondary) and
(ii) that it shall be required to advance the full amount of expenses incurred by an Indemnified 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 Indemnifying Party further agrees that no advancement or payment of indemnification or insurance by
such other sources on behalf of an Indemnified Party with respect to any claim for which such Indemnified Party has sought indemnification from an Indemnifying Party shall affect the foregoing, and any other sources of indemnification shall have a
right of contribution and/or be subrogated to the extent of such advancement or indemnification payment to all of the rights of recovery of such Indemnified Party against the Indemnifying Party. 

  
 22 

 (f) If any Third Party Claim shall be brought against a member of each party’s Group,
then such Action shall be deemed to be a SpinCo Assumed Action or a Parent Assumed Action in accordance with Section 5.02, to the extent applicable, and the party as to which the Action primarily relates shall be deemed to be the Indemnifying
Party for the purposes of this Article 6. In the event of any Action in which the Indemnifying Party is not also named defendant, at the request of either the Indemnified Party or the Indemnifying Party, the parties will use reasonable efforts to
substitute the Indemnifying Party or its applicable Affiliate for the named defendant in the Action. 
 (g) Notwithstanding the foregoing,
this Agreement shall not apply to indemnification, or responsibility for Losses, related to Tax matters. The procedures for such indemnification, and the allocation of such responsibility, shall be governed by the Tax Matters Agreement. 

Section 6.05. Calculation of Indemnification Amount. Any indemnification amount pursuant to Section 6.03 shall, subject to
Section 6.04(e), be paid (i) net of any amounts actually recovered by the Indemnified Party under applicable insurance policies or from any other Person alleged to be responsible therefor, and (ii) taking into account any Tax Benefit
(as defined in the Tax Matters Agreement) actually realized by the Indemnified Party (using the methodology set forth in Section 12(d) of the Tax Matters Agreement to determine the amount of any such Tax Benefit) arising from the incurrence or
payment of the relevant Losses. Subject to Section 6.04(e), if the Indemnified Party receives any amounts under applicable insurance policies from any other Person alleged to be responsible for any Losses, subsequent to an indemnification
payment by the Indemnifying Party in respect thereof, then such Indemnified Party shall promptly reimburse the Indemnifying Party for any payment made by such Indemnifying Party in respect thereof up to the amount received by the Indemnified Party
from such insurance policy or Person, as applicable. The Indemnifying Party shall not be liable for any Losses under Section 6.02 or Section 6.03 to the extent such Losses are punitive or exemplary damages (other than any such Losses
actually paid to Third Parties). 
 Section 6.06. Contribution. If for any reason the indemnification provided for in
Section 6.02 or Section 6.03 is unavailable to any Indemnified Party, or insufficient to hold it harmless, then the Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses in
such proportion as is appropriate to reflect the relative fault of the Parent Group, on the one hand, and the SpinCo Group, on the other hand, in connection with the conduct, statement or omission that resulted in such Losses. 

Section 6.07. Survival of Indemnities. The rights and obligations of any Indemnified Party or Indemnifying Party under this
Article 6 shall survive the sale or other transfer of any party of any of its assets, business or liabilities, including the Merger. 

  
 23 

 Section 6.08. Exclusive Remedy. 

(a) From and after the Distribution Effective Time , the sole and exclusive remedy of a party with respect to any and all claims relating to
this Agreement or the transactions contemplated hereby (other than claims of, or causes of action arising from, fraud and except for seeking specific performance or other equitable relief to require a party to perform its obligations under this
Agreement to the extent permitted hereunder and except as otherwise provided herein or in any Ancillary Agreement or other contract or agreement) will be pursuant to the indemnification provisions set forth in this Article 6 or, in the case of
indemnification claims for Tax and Tax Related Losses addressed in the Tax Matters Agreement, the Tax Matters Agreement. In furtherance of the foregoing, each party hereby waives, from and after the Distribution Effective Time , any and all rights,
claims and causes of action (other than pursuant to the indemnification provisions set forth in this Article 6 and the Tax Matters Agreement and other than claims of, or causes of action arising from, fraud and except for seeking specific
performance or other equitable relief to require a party to perform its obligations under this Agreement to the extent permitted hereunder and except as otherwise provided herein or in any Ancillary Agreement or other contract or agreement) that
such party or its Affiliates may have against the other party or any of its Affiliates, or their respective directors, officers and employees, arising under or based upon any applicable Laws and arising out of the transactions contemplated by this
Agreement. 
 (b) Notwithstanding any other provision hereof, from and after the Distribution Effective Time , except for [•]7 the sole and exclusive remedy of the Parent Group and the SpinCo Group with respect to any and all indemnification claims for Taxes and Tax-Related Losses
addressed in the Tax Matters Agreement shall be as set forth in the Tax Matters Agreement.

 SECTION 3.2 Exchange of Certificates. 

(a) Pursuant to Section 3.02 of the Separation Agreement, the Exchange Agent (as defined in the Separation
Agreement), if any, and the Distribution Agent (as defined in the Separation Agreement) shall hold, for the account of the relevant SpinCo shareholders, the global certificate(s) representing all of the outstanding shares of SpinCo common stock
transferred in the Distribution. 
 (b) Prior to or at the Effective Time, or as otherwise reasonably requested by SpinCo, Echo shall deposit
with the Exchange Agent, if any, and the Distribution Agent, as applicable, for the benefit of the holders of shares of SpinCo common stock, for exchange in accordance with this Article 3 through the Exchange Agent or Distribution Agent, as
the case may be, evidence in book entry form representing the shares of Echo Common Stock issuable pursuant to this Article 3 in exchange for outstanding shares of SpinCo common stock (such shares of Echo Common Stock, together with any
dividends or distributions with respect thereto, being hereafter referred to as the “Exchange Fund”). For the purposes of such deposit, Echo shall assume that there will not be any fractional shares of Echo Common Stock. The
Exchange Agent, if any, and the Distribution Agent shall, pursuant to irrevocable instructions, deliver the Echo Common Stock to be issued pursuant to this Article 3 out of the Exchange Fund. The Exchange Fund shall not be used for any other
purpose. 
 (c) None of the parties hereto, the Exchange Agent and the Distribution Agent shall be liable to any Person in respect of any
shares of SpinCo common stock or Echo Common Stock (in either case for any dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any abandoned property, escheat or similar law.

 SECTION 3.3 No Fractional Shares. 

(a) No certificates or scrip representing fractional shares of Echo Common Stock shall be issued upon the conversion of SpinCo common stock
pursuant to Section 3.1, and such fractional share interests shall not entitle the owner thereof to vote or to any rights of a holder of Echo Common Stock. For purposes of this Section 3.3, all
fractional shares to which a single record holder would be entitled shall be aggregated. 
 (b) Fractional shares of Echo Common Stock that
would otherwise be allocable to any former holders of SpinCo common stock in the Merger shall be aggregated, and no holder of SpinCo common stock shall receive cash equal to or greater than the value of one full share of Echo Common Stock. The
Exchange Agent, if any, and the Distribution Agent shall cause the whole shares obtained from aggregating fractional shares that would otherwise remain across all holders of SpinCo common stock to be sold, in the open market or otherwise as
reasonably directed by MCK, and in no case later than 20 business days after the Effective Time. The Exchange Agent, if any, and the Distribution Agent, as the case may be, shall make available the net proceeds thereof, after deducting any required
withholding Taxes and brokerage charges, commissions and transfer Taxes, on a pro rata basis, without interest, as soon as practicable to the holders of SpinCo common stock entitled to receive such cash. Payment of cash in lieu of fractional
shares of Echo Common Stock shall be made solely for the purpose of avoiding the expense and inconvenience to Echo of issuing fractional shares of Echo Common Stock and shall not represent separately

bargained-for consideration. Provided that Echo issues to the relevant agent the number of shares required to be issued by Echo to such agent pursuant to
Section 3.3, Echo shall have no liability whatsoever to any holders of SpinCo common stock with respect to cash delivered in lieu of fractional shares. As used herein, the term “Tax” has the meaning set forth in the Tax Matters
Agreement (substantially in the form set forth on Exhibit B) to be entered into by and among Echo, MCK and SpinCo prior to the Distribution (the “Tax Matters Agreement”). 

SECTION 3.4 Withholding Rights. Echo, the Distribution Agent and the Exchange Agent (if any), as the case may be, shall deduct and
withhold from the consideration otherwise required to be paid pursuant to this Agreement such amounts as may be required to be deducted and withheld under the Code or any provision of state, local or foreign Tax Law, and shall remit such amounts to
the relevant governmental authority. Any withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Persons otherwise entitled thereto.

(a) Amended Returns. Any amended Tax Return or claim for a refund with respect to any member of the SpinCo Group may be made only by the
party responsible for preparing the original Tax Return with respect to such member of the SpinCo Group pursuant to Section 5. Such party shall not file or cause to be filed any such amended Tax Return or claim for a refund without the prior
written consent of the other party, which consent shall not be unreasonably withheld, conditioned or delayed, if such filing, assuming it is accepted, could reasonably be expected to change the Tax liability of such other party (or any Affiliate of
such other party) for any Taxable period (including, for the avoidance of doubt, the amount of any Tax Attributes allocable under Section 6 to such other party (or any Affiliate of such other party)). 

(b) Carryback of Tax Attributes. 

(i) To the extent permitted by Applicable Tax Law, Acquiror shall cause the SpinCo Group to elect to forego carrybacks of any
Tax Attributes of the SpinCo Group to a Pre-Distribution Period. 
 (ii) If Acquiror
is unable to forego carrybacks of any Tax Attributes of the SpinCo Group to a Pre-Distribution Period, the Parent Group shall, at the request of Acquiror and at Acquiror’s sole expense, file any amended
Tax Returns reflecting such carryback (unless such filing, assuming it is accepted, could reasonably be expected to increase by more than a de minimis amount, the Tax liability of Parent or any of its Affiliates for any Taxable period). If the
Parent Group (or any member thereof) receives (or realizes) a refund as a result of such a carryback, Parent shall promptly remit the amount of such refund to Acquiror in accordance with Section 8(b). 

(c) Carryforwards to Separate Tax Returns. If a portion or all of any Tax Attribute is allocated to a member of a Combined Group
pursuant to Section 6, and is carried forward to a SpinCo Separate Tax Return, any Tax Benefits arising from such carryforward shall be retained by the Acquiror Group. If a portion or all of any Tax Attribute is allocated to a member of a
Combined Group pursuant to Section 6, and is carried forward to a Parent Separate Tax Return, any Tax Benefits arising from such carryforward shall be retained by the Parent Group.

thereon actually received) received by any member of the Parent Group or any member of the SpinCo Group, other than any Tax Benefits (or any amounts in respect of Tax Benefits) to which SpinCo or Acquiror is entitled pursuant to Section 8(b).
Neither SpinCo nor Acquiror shall be entitled to any Tax Benefits received by any member of the Parent Group or the SpinCo Group, except as set forth in Section 8(b).

any Tax allocated to the JV or a member of the SpinCo Group under this Agreement (including, for the avoidance of doubt, any amounts allocated to the W pursuant to Section 4(c)(iii)), or (ii) by a member of the SpinCo Group in respect of a
Post-Distribution Period. 
 (c) A Company receiving (or realizing) a Tax Benefit (a “Tax Benefit Recipient”) to which
another Company is entitled hereunder shall pay over the amount of such Tax Benefit (including interest received from the relevant Taxing Authority, but net of any Taxes imposed with respect to such Tax Benefit and any other reasonable costs) within
thirty (30) days of receipt thereof (or from the due date for payment of any Tax reduced thereby); provided, however, that the other Company, upon the request of such Tax Benefit Recipient, shall repay the amount paid to the other
Company (plus any penalties, interest or other charges imposed by the relevant Taxing Authority) in the event that, as a result of a subsequent Final Determination, a Tax Benefit that gave rise to such payment is subsequently disallowed.

 (iii) in the case of any other action that would reasonably
be expected to be inconsistent with the covenants contained in (b), if either: (A) SpinCo or Acquiror notifies Parent of its proposal to take such action and Acquiror and Parent obtain a ruling from the IRS to the effect that such action
will not affect the Intended Tax-Free Treatment (a “Favorable Tax Ruling”), provided that Acquiror agrees in writing to bear any expenses associated with obtaining such a ruling and,
provided further that the Acquiror Group shall not be relieved of any liability under Section 12(a) of this Agreement by reason of seeking or having obtained such a ruling; or (B) SpinCo or Acquiror notifies

timely protective election under Section 336(e) of the Code and the Treasury regulations issued thereunder for any member of the SpinCo Group that is a domestic corporation for U.S. federal income Tax purposes with respect to the Distribution
(a “Section 336(e) Election”). It is intended that a Section 336(e) Election will have no effect unless the Distribution is a “qualified stock disposition,” as defined in Treasury regulations Section 1.336(e)-1(b)(6), by reason of the application of Treasury regulations Section 1.336-1(b)(5)(i)(B) or Treasury regulations
Section 1.336-1(b)(5)(ii). 
 (b) Parent TRA. If and to the extent that there is a
Disqualifying Action and the resulting Taxes (including any Taxes attributable to the Section 336(e) Election) are allocated to Parent pursuant to Section 4, (i) Parent shall be entitled to periodic payments from SpinCo equal 

 

	5 	 NTD: Amount equal to 5% of the equity value of SpinCo.

  
 24 

 
to the product of (x) 85% of the tax savings arising from the step-up in tax basis resulting from the Section 336(e) Election and (y) the
percentage of such Taxes that are allocated to Parent pursuant to Section 4, and (ii) the Parties shall negotiate in good faith the terms of a tax receivable agreement to govern the calculation of such payments, with it being agreed that
the terms of such agreement shall be substantially similar to the terms of the MCK Tax Receivable Agreement; provided that any such tax saving in clause (i) shall be determined using a “with and without” methodology (treating
any deductions or amortization attributable to the step-up in tax basis resulting from the Section 336(e) Election as the last items claimed for any taxable year, including after the utilization of any
carryforwards).6 
 SECTION 12. Indemnities. 

(a) Acquiror Indemnity to Parent. The Acquiror as successor to SpinCo shall be obligated to indemnify (and the JV and each other member
of the JV Group shall jointly and severally be obligated to pay to Acquiror all amounts necessary to allow Acquiror to indemnify) Parent and the other members of the Parent Group against, and hold them harmless, without duplication, from
(i) any payments by Parent of any Tax liability and any associated Tax-Related Losses allocated to SpinCo pursuant to Section 4; provided that, the amount of such indemnity shall be limited to
the amount of any payment of Tax or Tax Related Losses required to be made by Parent or any member of the Parent Group and, for the avoidance of doubt, shall be calculated without regard to any harm to Parent or any member of the Parent Group
relating to any equity or other interests in Parent or any other member of the Parent Group directly or indirectly in the JV Group or in the Acquiror Group and (ii) notwithstanding any provisions of this Agreement, the Separation Agreement, the
Merger Agreement, or otherwise, any Damages arising from or relating to, directly or indirectly, whether by operation of the provisions of this Agreement, the Separation Agreement, the Merger Agreement or otherwise, any failure of the Effective Time
to occur immediately following the Distribution Effective Time primarily as a result of any failure by Acquiror to perform its obligation to close the Merger in accordance with the Merger Areement. 

(b) Parent Indemnity to Acquiror. Except in the case of any liabilities described in Section 12(a), Parent and each
other member of the Parent Group will jointly and severally indemnify Acquiror and the other members of the Acquiror Group against, and hold them harmless, without duplication, from: 

(i) any Tax liability and any associated Tax-Related Losses allocated to Parent
pursuant to Section 4; 
 (ii) any Taxes imposed on any member of the SpinCo Group or Acquiror Group under Treasury
regulations Section 1.1502-6 (or similar or analogous provision of state, local or foreign law) as a result of any such member being or having been a member of a Combined Group; and 

 

	6 	 NTD: Parent reserves the right to omit this Section 11(b) from the executed Tax Matters Agreement.

  
 25 

 (iii) notwithstanding any provisions of this Agreement, the Separation
Agreement, the Merger Agreement, or otherwise, any Damages arising from or relating to, directly or indirectly, whether by operation of the provisions of this Agreement, the Separation Agreement, the Merger Agreement or otherwise, any failure of the
Effective Time to occur immediately following the Distribution Effective Time primarily as a result of any failure by MCK or SpinCo to perform its obligation to close the Merger in accordance with the Merger Agreement. 

(c) Discharge of Indemnity. Acquiror, the JV, Parent and the members of their respective Groups shall discharge their obligations under
Section 12(a) or Section 12(b) hereof, respectively, by paying the relevant amount in accordance with Section 13, within 30 Business Days of demand therefor. Any such demand shall include a statement showing the amount
due under Section 12(a) or Section 12(b), as the case may be. Notwithstanding the foregoing, if any member of the Acquiror Group or any member of the Parent Group disputes in good faith the fact or the amount of its
obligation under Section 12(a) or Section 12(b), then no payment of the amount in dispute shall be required until any such good faith dispute is resolved in accordance with Section 24 hereof;
provided, however, that any amount not paid within thirty (30) Business Days of demand therefor shall bear interest as provided in Section 14. 

(d) Tax Benefits. If an indemnification obligation of any Indemnifying Party under this Section 12 arises in
respect of an adjustment that makes allowable to an Indemnitee any Tax Benefit (other than a Tax Benefit resulting from a Section 336(e) Election, which shall be governed exclusively by Section 11) which would not, but
for such adjustment, be allowable, then any such indemnification obligation shall be an amount equal to (i) the amount otherwise due but for this Section 12(d) minus (ii) the reduction in actual cash Taxes payable
by the Indemnitee in the taxable year such indemnification obligation arises and the two taxable years following such year, determined on a “with and without” basis. 

(e) Sole Remedy. Parent (on behalf of itself and each member of the Parent Group) covenants and agrees that the remedies provided for in
Section 12(a) shall constitute the sole and exclusive remedy for all Damages, including any Tax liabilities and any associated Tax-Related Losses, that Parent or any member of the Parent Group may suffer
or incur arising from, or directly or indirectly relating to any breach or violation of any of the representations, warranties, covenants and agreements contained in this Agreement, the various Tax Representation Letters, under Section 11.04(e)
of the LLC Agreement, or Section 5.15 of the Contribution Agreement by the Acquiror, the JV, SpinCo, and any member of the Acquiror Group, JV Group or SpinCo Group, or otherwise relating to the failure of the Controlled Transfer, the
Distribution, or the Merger to occur or receive the Intended Tax Treatment, and the Parent (on behalf of itself and each member of the Parent Group) hereby irrevocably waives any other rights or remedies (whether at law or in equity and whether
based on contract, tort, statute or otherwise) that it may otherwise have had, now have or may in the future have against the Acquiror, the JV, SpinCo, and any member of the Acquiror Group, JV Group or SpinCo Group or any of their respective direct
or indirect Affiliates, officers, managers, directors, employees, advisors, stockholders, members, consultants, investment bankers, brokers, controlling persons, partners or other representatives or agents thereof arising from, or directly or
indirectly relating to any breach or violation of any of the representations, warranties, covenants and agreements contained in this Agreement, the various Tax Representation Letters, under Section 11.04(e) of the LLC Agreement, or
Section 5.15 of the Contribution Agreement by the Acquiror, the JV, SpinCo, and any member of the Acquiror Group, JV Group or SpinCo Group and covenants not to sue or otherwise assert any claim (or assist any Person in suing or otherwise
asserting any claims) encompassed by the foregoing covenant, agreement and waiver; provided that the foregoing shall not apply to any party’s right to seek specific performance pursuant to Section 20 hereof. 

  
 26 

 SECTION 13. Acquiror Shareholders Not Parties. For the avoidance
of doubt, and notwithstanding any provision of this Agreement or any other Transaction Document to the contrary, (i) no Person who is a direct or indirect shareholder, member, or interest holder in Acquiror is a party to, or is bound by, or
makes any representations, warranties, or covenants, or indemnities pursuant to, this Agreement (unless such Person is Parent, SpinCo, Acquiror, or any of their respective Subsidiaries), and (ii) notwithstanding that certain Persons described
in the foregoing sentence make the representations, warranties, and covenants in the Principal Shareholder Letter, such Persons shall not be liable thereunder, under any Transaction Document, or otherwise by reason of having breached such
representations, warranties, or covenants. 
 SECTION 14. Payments. 

(a) Timing. All payments to be made under this Agreement (excluding, for the avoidance of doubt, any payments to a Taxing Authority
described herein) shall be made in immediately available funds. Except as otherwise provided, all such payments will be due thirty (30) Business Days after the receipt of notice of such payment or, where no notice is required, thirty
(30) Business Days after the fixing of liability or the resolution of a dispute (the “Due Date”). Payments shall be deemed made when received. Any payment that is not made on or before the Due Date shall bear interest at the
rate equal to the “prime” rate as published on such Due Date in the Wall Street Journal, Eastern Edition, for the period from and including the date immediately following the Due Date through and including the date of payment. With respect

to Parent, which member of the Acquiror Group will make or receive such payment.

by Applicable Tax Law, any payment made by Parent or any member of the Parent Group to Acquiror or any member of the Acquiror Group, or by Acquiror or any member of the Acquiror Group to Parent or any member of the Parent Group, pursuant to this
Agreement, the Separation Agreement, the Merger Agreement or any other Exit Transaction Document that relates to Taxable periods (or portions thereof) ending on or before the Distribution Date shall be treated by the parties hereto for all Tax
purposes as a distribution by SpinCo to Parent, or capital contribution from Parent to SpinCo, as the case may be; provided, however, that any payment made pursuant to [ ]7 shall
instead be treated as if the party required to make a payment of received amounts had received such amounts as agent for the other party; provided further that any payment made pursuant to
[ ]8 shall instead be treated as a payment for services. In the event that a Taxing Authority asserts 

that a party’s treatment of a payment described in this Section 14(b) should be other than as required herein, such party shall use its
commercially reasonable efforts to contest such assertion in a manner consistent with Section 16 of this Agreement. 
  

	7 	 NTD: Insert cross-references to provisions in other Transaction Agreements under which payments will be made
between the parties that are not treated as contributions or distributions. 

	8 	 NTD: Insert cross-references to provisions in other Transaction Agreements under which payments will be made

 27 

 (c) No Duplicative Payment. It is intended that the provisions of this Agreement

SECTION 15. Communication and Cooperation. 

(a) Consult and Cooperate. SpinCo, Parent and Acquiror shall consult and cooperate (and shall cause each other member of their
respective Groups to consult and cooperate) fully at such time and to the extent reasonably requested by the other party in connection with all matters subject to this Agreement. Such cooperation shall include, without limitation: 

(i) the retention, and provision on reasonable request, of any and all information including all books, records, documentation

 29 

 (G) to the extent required by the rules and regulations of the SEC or stock
exchange rules, including any disclosure contemplated under the Registration Rights Agreement; or 
 (H) if the prior written
consent of all of the Directors on the Board shall have been obtained. 
 Nothing contained herein shall prevent the use of Confidential Information in
connection with the assertion or defense of any claim by or against the JV or any Member and nothing contained in this Section 15(d) shall be deemed to restrict any stockholder’s ability to monetize its equity investment in compliance with
applicable securities laws. 
 Notwithstanding the foregoing, the JV and each of the Members acknowledge that each of the BX Investors and the H&F
Investors and their Affiliates may provide Confidential Information to its existing and potential limited partners, members and other investors; provided that no BX Investor and no H&F Investor shall provide any non-public financial information or competitively or strategically sensitive information about the JV or any of its Subsidiaries to (a) any limited partner that is not subject to customary confidentiality and non-use restrictions with respect to such information (subject to customary exceptions) or (b) to any other Person in the course of investing or fundraising activities that is not subject to customary

Affiliates, the JV or any of its Subsidiaries or the financial condition, business, operations or prospects of the Members or any of their respective Affiliates or the JV or any of its Subsidiaries in the possession of or furnished to the JV or any
Member, as applicable (including by virtue of any Member’s present or former right to designate a Director); provided that the term “Confidential Information” shall not include information that (i) is or becomes generally
available to the public other than as a result of a disclosure by such Person or its Affiliates or any of their respective Representatives in violation of this Agreement, (ii) was available to such Person on a

Person; provided that, notwithstanding anything to the contrary contained herein, “Confidential Information” in the possession of any of the Initial 

  
 30

Members shall be obligated to keep or to cause to be kept such information confidential and to use or cause to be used such information in accordance with the provisions of this Section 15(d) as fully as if such Member did not have access to
such information prior to the Closing but only received such information after the Closing. For the avoidance of doubt, the JV and each Member (as defined in the LLC Agreement) acknowledge and agree that each Member and the Echo Shareholders (as
defined in the LLC Agreement) may incidentally develop or receive from third parties information not known by such recipient to have been obtained in violation of this Agreement that is the same as or similar to the Confidential Information, and
that nothing in this Agreement restricts or prohibits any Member or the Echo Shareholders (by itself or through a third party) from developing, receiving or disclosing such information, or any products, services, concepts, ideas, systems or
techniques that are similar to or compete with the products, services, concepts, ideas, systems or techniques contemplated by or embodied in the Confidential Information. 

(iv) Notwithstanding anything to the contrary in this Agreement, the JV, each Member, their respective Affiliates and their

provided to the JV or the Member relating to such tax treatment and tax structure; provided that the foregoing does not constitute authorization to disclose information identifying the JV, any Member (or its Representatives), any parties to
transactions engaged in by the JV or (except to the extent relating to such tax structure or tax treatment) any nonpublic commercial or financial information.

meaning set forth in the LLC Agreement. 
 SECTION 16. Audits and Contest. 

(a) Notice. Each of Parent, SpinCo and Acquiror shall promptly notify the other parties in writing upon the receipt from a relevant
Taxing Authority of any notice of a Tax Proceeding that may give rise to an indemnification obligation under this Agreement; provided that a party’s right to indemnification under this Agreement shall not be limited in any way by a
failure to so notify, except to the extent that the Indemnifying Party is prejudiced by such failure.

a Combined Group (as such), (ii) any member of the Parent Group and (iii) any member of the SpinCo Group relating solely to a Pre-Distribution Period (a “Parent Tax Proceeding”). Parent
shall have absolute discretion with respect to any decisions to be made, or the nature of any action to be taken, with respect to any Parent Tax Proceeding; provided, however, that to the extent that any Parent Tax Proceeding is
reasonably likely to give rise to an indemnity obligation of SpinCo or Acquiror under Section 12 hereof, materially increase the Taxes payable by or allocated to any member of the Acquiror 

  
 31

Acquiror informed of all material developments and events relating to any such Parent Tax Proceeding, (ii) at its own cost and expense, Acquiror shall have the right to participate in (but not to control) the defense of any such Parent Tax
Proceeding, and (iii) Parent shall not settle or compromise any such contest without Acquiror’s written consent, which consent may not be unreasonably withheld, conditioned or delayed. If the Parent Group acknowledges in writing that it is
liable for the Taxes at issue in any Parent Tax Proceeding subject to the proviso in the previous sentence, the rights of Acquiror in such proviso shall not apply to such Parent Tax Proceeding to the extent such Parent Tax Proceeding relates to the
Taxes that are the subject of such acknowledgment. 
 (c) Distribution Taxes. If any Parent Tax Proceeding relating to Distribution
Taxes is reasonably likely to give rise to an indemnity obligation of the Acquiror as successor to SpinCo or the JV Group under Section 12 hereof, Acquiror and Parent shall exercise joint control over the disposition of such Parent Tax
Proceeding (and, for the avoidance of doubt, shall keep each other informed of all material developments with respect to such Parent Tax Proceeding to the extent the other party is not otherwise informed thereof). Parent shall otherwise have the
right to elect to control any Parent Tax Proceeding relating to Distribution Taxes; provided that Parent shall keep Acquiror informed of all material developments. 

(d) Acquiror Control. Acquiror shall have the right to control any Tax Proceeding with respect to SpinCo or any member of the SpinCo
Group relating to one or more members of the SpinCo Group and to any Post-Distribution Period (an “Acquiror Tax Proceeding”). Acquiror shall have absolute discretion with respect to any decisions to be made, or the nature of any
action to be taken, with respect to any Acquiror Tax Proceeding; provided, however, that to the extent any such matter is reasonably likely to give rise to a claim for indemnity by SpinCo or Acquiror against Parent under
Section 12(b) of this Agreement, (i) Acquiror shall keep Parent informed of all material developments and events relating to such Acquiror Tax Proceeding, (ii) at its own cost and expense, Parent shall have the right to participate in
(but not to control) the defense of any such Acquiror Tax Proceeding and (iii) Acquiror shall not settle or compromise any such tax claim without the prior written consent of Parent (which shall not be unreasonably withheld, conditioned or
delayed). If the Acquiror Group acknowledges in writing that it is liable for the Taxes at issue in any Acquiror Tax Proceeding subject to the proviso in the previous sentence, the rights of Parent in such proviso shall not apply to such Acquiror
Tax Proceeding to the extent such Acquiror Tax Proceeding relates to the Taxes that are the subject of such acknowledgment.

party is entitled at Law or in equity. Each party hereto further agrees that no other party or any other Person will be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy
referred to in this Section 20, and each party hereto irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

absolute discretion, the parties hereby expressly disclaiming any implied duty of good faith and fair dealing or similar concept.

 SECTION 22. Entire Agreement; Amendments and Waivers. 

(a) Entire Agreement. 

(i) This Agreement and the other Transaction Documents, including any related annexes, schedules and exhibits, as well as any
other agreements and documents referred to herein and therein, together constitute the entire agreement among the parties with respect to the subject matter hereof and thereof and supersede all prior negotiations, agreements and understandings of
the parties of any nature, whether oral or written, with respect to such subject matter. If there is a conflict between any provision of this Agreement and a provision of any other Transaction Document, the provision of this Agreement will control
unless specifically provided otherwise in this Agreement. 
 (ii) THE PARTIES ACKNOWLEDGE AND AGREE THAT NO REPRESENTATION,
WARRANTY, PROMISE, INDUCEMENT, UNDERSTANDING, COVENANT OR AGREEMENT HAS BEEN MADE OR RELIED UPON BY ANY PARTY OTHER THAN THOSE EXPRESSLY SET FORTH IN THIS AGREEMENT AND IN THE OTHER TRANSACTION DOCUMENTS, INCLUDING ANY CERTIFICATE ISSUED IN
ACCORDANCE THEREWITH. 
 (b) Amendments and Waivers. 

(i) This Agreement may be amended, and any provision of this Agreement may be waived, if and only if such amendment or waiver,
as the case may be, is in writing and signed, in the case of an amendment, by the parties or, in the case of a waiver, by the party against whom the waiver is to be effective. 

(ii) No failure or delay by either party in exercising any right, power or privilege under this Agreement shall operate as a
waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. Except as otherwise provided herein, no action taken pursuant to this Agreement,
including any investigation by or on behalf of any party, shall be deemed to constitute a waiver by the party taking such action of compliance with any representations, warranties, covenants or agreements contained in this Agreement. Any term,
covenant or condition of this Agreement may be waived at any time by the party that is entitled to the benefit thereof, but only by a written notice signed by such party expressly waiving such term, covenant or condition. The waiver by any party of
a breach of any provision hereunder shall not operate or be construed as a waiver of any prior or subsequent breach of the same or any other provision hereunder. 

SECTION 23. Governing Law and Interpretation. The validity, interpretation and enforcement of this Agreement will be governed by
the Laws of the State of Delaware, without regard to the conflict of Laws provisions thereof that would cause the Laws of another state to apply. 

  
 35

Agreement, including but not limited to whether a Tax liability is a liability of the Parent Group, the SpinCo Group or the Acquiror Group, the parties shall work together in good faith to resolve such dispute within thirty (30) days. In the
event that such dispute is not resolved, upon written notice by a party after such thirty (30)-day period, the matter shall be referred to a U.S. Tax counsel or other Tax advisor of recognized national
standing (the “Tax Arbiter”) that will be jointly chosen by the Parent and Acquiror; provided, however, that, if the Parent and the Acquiror do not agree on the selection of the Tax Arbiter after five (5) days of

mutual agreement of the other members within the following ten (10)-day period. Each decision of a panel Tax Arbiter shall be made by majority vote of the members. The Tax Arbiter may, in its discretion,
obtain the services of any third party necessary to assist it in resolving the dispute. The Tax Arbiter shall furnish written notice to the parties to the dispute of its resolution of the dispute as soon as practicable, but in any event no later
than ninety (90) days after acceptance of the matter for resolution. Any such resolution by the Tax Arbiter shall be binding on the parties, and the parties shall take, or cause to be taken, any action necessary to implement such resolution.
All fees and expenses of the Tax Arbiter shall be shared equally by the parties to the dispute. 
 SECTION 25. Counterparts.
This Agreement may be executed in multiple counterparts (any one of which need not contain the signatures of more than one party), each of which will be deemed to be an original but all of which taken together will constitute one and the same
agreement. This Agreement, and any amendments hereto, to the extent signed and delivered by means of a facsimile machine or other electronic transmission, will be treated in all manner and respects as an original agreement and will be considered to

has the power and authority to execute, deliver and perform this Agreement, that this Agreement has been duly authorized by all necessary corporate action on the part of such party, that this Agreement constitutes a legal, valid and binding
obligation of each such party, and that the execution, delivery and performance of this Agreement by such party does not contravene or conflict with any provision or law or of its charter or bylaws or any agreement, instrument or order binding on

[Date] 
 [Tax Advisor] 

Ladies and Gentlemen: 
 In connection with the
MCK Separation Tax Opinion to be delivered by MCK Tax Advisor , pursuant to Section 5.2(c) of the Agreement and Plan of Merger (the “Merger Agreement”),1 dated as of June
[6], 2016, between McKesson Corporation, a Delaware corporation (“McKesson”), [•], a Delaware corporation (“SpinCo”) and HCIT Holdings, Inc., a Delaware corporation (“Echo”), you have requested
certain representations from Echo. This officer’s certificate (“Officer’s Certificate”) is being provided to you in response to that request. 

General 
  

	1.	 The facts relating to the Controlled Transfer, the Distribution and the Merger pursuant to the Separation
Agreement, the other Transaction Documents and the Applicable SEC Filings, insofar as those facts pertain to Echo and its Affiliates, are true, correct and complete in all material respects, and insofar as those facts pertain to McKesson and its
Affiliates and, with respect to facts that pertain to the period prior to the Distribution Effective Time, SpinCo, are, to the knowledge of Echo, true, correct and complete in all material respects. The Merger and, to the knowledge of Echo, the
Controlled Transfer and the Distribution will be consummated in accordance with the Transaction Documents (without waiver or modification of any provision thereof) and the descriptions contained in the Applicable SEC Filings. 

 

	2.	 Other than with respect to (i) the Controlled Transfer, the Distribution and the Merger and those
agreements described or referred to in the Transaction Documents and the Applicable SEC Filings and (ii) ordinary course commercial arrangements that were not entered into in contemplation of, or in connection with, the Controlled Transfer, the
Distribution and the Merger, there are no agreements, arrangements or understandings, either written or oral, between or among (a) McKesson and Echo or (b) SpinCo and Echo. For purposes of this representation, “Echo” refers to
Echo, its Affiliates, its shareholders that will hold 10% or more of the voting power or value of all Echo shares (“10% Holders”), and, to the knowledge of Echo, its shareholders that are not 10% Holders, and “McKesson”
and “SpinCo” each refers to such Person, its Affiliates and, to the knowledge of Echo with respect to McKesson, its shareholders. 

  

	3.	 None of Echo and its Affiliates will take any position on any federal, state, or local income or franchise tax
return or take any other tax or financial reporting position that is inconsistent with the Intended Tax-Free Treatment (as defined in the Tax Matters Agreement) or any of the representations contained herein.

  

	1 	 Except where noted, each capitalized term used and not otherwise defined herein has the meaning ascribed to it
in the Merger Agreement, Separation and Distribution Agreement (the “Separation Agreement”) and other “Transaction Documents” (as defined in the Amended and Restated Limited Liability Company Agreement (the
“LLC Agreement”)). 

  
 2 

	4.	 The undersigned is authorized to make all of the representations and certifications set forth herein on behalf
of Echo and its Affiliates. 

 Active Trade or Business 

 

	5.	 Following the Merger, the Echo SAG2 intends to continue
the active conduct of the Controlled Business (as defined in the Tax Matters Agreement), independently and with its separate employees. There is no planned or intended substantial reduction in business activity relating to the Controlled Business.

  

	6.	 There is no plan or intention, following the Merger, to liquidate any member of the Echo SAG, to merge any
member of the Echo SAG with any other entity outside the Echo SAG or to sell or otherwise dispose of the assets or shares of any member of the Echo SAG to an extent that would cause the Echo SAG to cease to be engaged in the Controlled Business.

 Device 
  

	7.	 There will be no plan or intention by Echo, directly or through any of its Subsidiaries, to redeem or purchase
any Echo Common Stock after the Merger, other than (a) unregistered or restricted Echo Common Stock that was held by shareholders of Echo immediately prior to the Merger, or (b) through Echo Common Stock purchases meeting the following
requirements: (i) there is a sufficient business purpose for the Echo Common Stock purchase; (ii) the Echo Common Stock to be purchased is widely held; (iii) the Echo Common Stock purchases will be made in the open market; and
(iv) the aggregate amount of Echo Common Stock purchased will not equal or exceed 20% of the outstanding Echo Common Stock. 

Code Section 355(e)3 

 

	8.	 To the knowledge of Echo, none of the Controlled Transfer, the Distribution or the Merger is, or will be, part
of a plan or series of related transactions (within the meaning of Treasury Regulations Section 1.355-7) pursuant to which one or more persons will acquire directly or indirectly common stock representing
a 50% or greater interest (within the meaning of Section 355(d)(4)) in McKesson or SpinCo (including any predecessor or successor to any such corporation). 

 

	2 	 For purposes of this representation letter, a corporation’s “SAG” or “separate
affiliated group” refers to a group made up of one or more chains of includible corporations connected through stock ownership if such corporation owns directly stock meeting the Stock Ownership Requirement (as defined below) in at least
one other includible corporation, and stock meeting the Stock Ownership Requirement in each of the includible corporations (except the parent) is owned directly by one or more of the other includible corporations. The “Stock Ownership
Requirement” is met if the stock owned represents at least 80% of the total voting power and at least 80% of the total value of the stock of such corporation. 

	3 	 Unless otherwise noted, all Section references herein refer to the Internal Revenue Code of 1986, as amended
(the “Code”), or to the Treasury Regulations promulgated thereunder. 

  
 3 

 The undersigned is authorized to make all the representations and certifications set forth
herein on behalf of Echo and the management thereof, and is familiar with the matters set forth herein and has made such investigations of factual matters as the undersigned has deemed reasonably necessary for purposes of making the representations
and statements herein. We understand that you will rely on this letter in rendering your opinion as to certain U.S. federal income tax consequences of the Controlled Transfer, the Distribution and the Merger. As of the date hereof, we believe that
all of the facts, representations and assumptions stated or referred to herein are consistent with the state of facts that will exist as of the Distribution Effective Time. We will immediately inform you if, after signing this letter, we have reason
to believe that any of the facts described herein, in the Merger Agreement, the Transaction Documents or the Applicable SEC Filings or any of the representations made in this letter are or have become untrue, incorrect or incomplete in any respect.
We understand that your opinion will be subject to certain limitations and qualifications, including that it may not be relied upon if any such facts or representations are not correct in all material respects. 

 

			
	Very truly yours,

 In connection with the
MCK Separation Tax Opinion to be delivered by MCK Tax Advisor, pursuant to Section 5.2(c) of the Agreement and Plan of Merger (the “Merger Agreement”),1 dated as of [•],
between McKesson Corporation, a Delaware corporation (“McKesson”), [•], a Delaware corporation (“SpinCo”) and HOT Holdings, Inc., a Delaware corporation (“Echo”), you have requested
certain representations from McKesson. This officer’s certificate (“Officer’s Certificate”) is being provided to you in response to that request. 

General 
  

	 	1.	 The facts relating to the Controlled Transfer, the Distribution and the Merger pursuant to the Separation
Agreement, the other Transaction Documents and the Applicable SEC Filings, insofar as those facts pertain to McKesson, its Affiliates and, with respect to facts that pertain to the period prior to the Distribution Effective Time, SpinCo, are true,
correct and complete in all material respects, and, insofar as those facts pertain to Echo and its Affiliates, are, to the knowledge of McKesson, true, correct and complete in all material respects. The Controlled Transfer, the Distribution and the
Merger will be consummated in accordance with the Transaction Documents, as amended (without waiver or modification of any provision thereof), and the descriptions contained in the Applicable SEC Filings. 

 

	 	2.	 Other than with respect to (i) the Controlled Transfer, the Distribution and the Merger and those
agreements described or referred to in the Transaction Documents and the Applicable SEC Filings, and (ii) ordinary course commercial arrangements that were not entered into in contemplation of, or in connection with, the Controlled Transfer,
the Distribution and the Merger, there are no agreements, arrangements, or understandings, either written or oral, between or among (a) McKesson and SpinCo, (b) McKesson and Echo or (c) SpinCo and Echo. For purposes of this
representation, “McKesson” refers to McKesson, its Affiliates, its shareholders that will hold 10% or more of the voting power or value of all McKesson shares (“10% Holders”), and, to the knowledge of McKesson, its
shareholders that are not 10% Holders, and “SpinCo” and “Echo” each refers to such Person, its Affiliates and, to the knowledge of McKesson with respect to Echo, its shareholders. 

 

	1 	 Except where noted, each capitalized term used and not otherwise defined herein has the meaning ascribed to it
in the Merger Agreement, Separation and Distribution Agreement (the “Separation Agreement”) and other “Transaction Documents” (as defined in the Amended and Restated Limited Liability Company Agreement (the
“LLC Agreement”)). 

  
 2 

	 	3.	 None of McKesson and its Affiliates will take any position on any federal, state, or local income or franchise
tax return or take any other tax or financial reporting position that is inconsistent with the Intended Tax-Free Treatment (as defined in the Tax Matters Agreement) or any of the representations contained
herein. 

  

	 	4.	 The undersigned is authorized to make all of the representations and certifications set forth herein on behalf

copyrighted articles that MTI purchased from a DRE of IP3 and resold to customers as part of the conduct of the Controlled Business and, more broadly, the Core MTS Business.

	 	15.	 From the MCK Contributions and until the Merger, (i) MCK IPCo and PST together owned Units representing,
in aggregate, more than 50% of JV’s total value, capital and profits interests and at least 50% of the total voting interests in JV and (ii) the combined balances of the Capital Accounts (as defined in the LLC Agreement) maintained in
respect of MCK IPCo and PST constituted more than 50% of the combined balances of the Capital Accounts maintained in respect of all members of JV. At all times from and after the MCK Contributions to and until the Distribution, MCK IPCo and PST were

	 	16.	 At no time prior to the Merger did W issue any equity interests other than Units.

activity conducted or its method of conducting business, such as its products or services offered, production capacity, assets owned or used, technology employed, sales, or distribution channels or locations, other than technological, operational,
and managerial changes in the ordinary course of business. At no time during the Five-Year Period was there a time in which no business activity was conducted, or a significant amount of time during which there was a substantial reduction in
business activity. There is no planned or intended substantial reduction in business activity relating to the MCK Business. 

  

	 	18.	 The Controlled Business experienced no substantial changes during the Five-Year Period in the type of business
activity conducted or its method of conducting business, such as its products or services offered, production capacity, assets owned or used, technology employed, sales, or distribution channels or locations, other than technological, operational

change in the type of business activity conducted or its method of conducting business, such as its products or services offered, production capacity, assets owned or used, technology employed, sales, or distribution channels or locations, other
than technological, operational, and managerial changes in the ordinary course of business. 

  

	 	20.	 There is not any plan or intention to liquidate any member of the McKesson SAG, to merge any member of the
McKesson SAG with any entity outside the McKesson SAG or to sell or otherwise dispose of the assets or shares of any member of the McKesson SAG, in each case, if such action would cause the McKesson SAG to cease to be engaged in the MCK Business.

  

	 	21.	 Other than pursuant to the Merger, there is not any plan or intention to liquidate any member of the SpinCo
SAG, to merge any member of the SpinCo SAG with any entity outside the SpinCo SAG, to sell or otherwise dispose of the assets or shares of any member of the SpinCo SAG, to liquidate JV, to merge JV with any entity, to sell or otherwise dispose of
the assets of JV (including any assets held through a DRE of JV), in each case, if such action would cause the SpinCo SAG to cease to be engaged in the Controlled Business. 

 

	 	22.	 Immediately after the Distribution, the fair market value of the gross assets of the MCK Business will be at
least [•]% of the fair market value of the total gross assets of the McKesson SAG. For purposes of this representation, in determining the fair market value of the total gross assets of the McKesson SAG and the MCK Business, all members of the
McKesson SAG are treated as one corporation. 

  
 5 

	 	23.	 Immediately after the Distribution, the fair market value of the gross assets of the Controlled Business will
be at least 25% of the fair market value of the total gross assets of the SpinCo SAG. For purposes of this representation, in determining the fair market value of the total gross assets of the SpinCo SAG and the Controlled Business (i) all
members of the SpinCo SAG are treated as one corporation; and (ii) the SpinCo SAG is treated as owning a ratable share of the gross assets of JV, in proportion to the combined ownership of MCK IPCo and PST of equity in JV.

 The Controlled Transfer and the Distribution 
  

	 	24.	 The Controlled Transfer and the Distribution were consummated under a single, integrated plan to be formulated,
approved and adopted by the boards of directors of each of McKesson and SpinCo. 

  

	 	25.	 SpinCo was formed solely to effect the Distribution and did not conduct any business or other activities prior
to the Controlled Transfer. 

  

	 	26.	 From the time of the formation of SpinCo, and throughout the period before and including the Distribution:
(i) the outstanding equity of SpinCo consisted solely of a single class of common stock that possessed, in the aggregate, 100% of the voting power, dividend rights, redemption rights, and liquidation rights with respect to the equity of SpinCo
(the “SpinCo Common Stock”); and (ii) other than the SpinCo Common Stock, there were no instruments or arrangements that could be treated as equity of SpinCo for U.S. federal income tax purposes. 

 

	 	27.	 Other than the SpinCo Common Stock, the Separation Agreement and the Merger Agreement, at no time prior to or
including the Controlled Transfer were there any outstanding warrants, options, convertible securities, or other type of interest or arrangement (i) pursuant to which any person may acquire equity in SpinCo, (ii) the entitlements of which
are determined in whole or in part by reference to the value of the SpinCo Common Stock or the profits or income of SpinCo or (iii) which otherwise bears economic entitlements similar to those of the SpinCo Common Stock. 

 

	 	28.	 Other than the Separation Agreement and the Merger Agreement, from the time of the formation of SpinCo, and
throughout the period ending with the Distribution, there were no existing, planned, or intended agreements, such as a voting trust, affecting the rights of any shareholder owning directly, or beneficially as a result of any agreement, any common
stock of McKesson or SpinCo.

	 	32.	 McKesson has not received and will not receive any cash or other property from SpinCo pursuant to the plan of
reorganization that includes the Controlled Transfer and the Distribution (excluding, for the avoidance of doubt, SpinCo Common Stock). 

  

	 	33.	 The aggregate gross fair market value of the assets McKesson transferred to SpinCo in the Controlled Transfer
approximately equaled the sum of (i) the fair market value of SpinCo Common Stock that McKesson received, (ii) the liabilities (whether indebtedness or other forms of obligations, including contingent obligations), assumed by SpinCo
pursuant to the Controlled Transfer (within the meaning of Section 357(d)) and (iii) the amount of liabilities, if any, to which the transferred assets were subject. 

 

	 	34.	 Other than liabilities of MCK lPCo, if any, under the Contribution Agreement, SpinCo did not (i) assume
any liabilities of McKesson (within the meaning of Section 357(d)) or (ii) discharge or extinguish any liabilities owed to SpinCo by McKesson. 

  

	 	35.	 Each of the total basis and the total fair market value of the assets transferred to SpinCo by McKesson in the
Controlled Transfer equaled or exceeded the sum of (i) the total amount of any liabilities assumed (within the meaning of Section 357(d)) by SpinCo in connection with the Controlled Transfer; (ii) the total amount of any liabilities
to which the assets transferred in the Controlled Transfer were subject (including, for this purpose, McKesson’s share of any W liabilities (within the meaning of Section 752)); and (iii) the total amount of any liabilities owed to
SpinCo by McKesson that were discharged or extinguished in connection with the Controlled Transfer. The fair market value of the assets of SpinCo exceeded the amount of its liabilities immediately after the Controlled Transfer.

  

	 	36.	 Other than the obligations of MCK lPCo, if any, under the Contribution Agreement, the liabilities of McKesson
assumed by SpinCo pursuant to the Controlled Transfer, if any, and the liabilities to which the assets transferred pursuant to the Controlled Transfer were subject, if any, were incurred by McKesson in the ordinary course of business and were
associated with the assets transferred. 

  

	 	37.	 No part of the SpinCo Common Stock that was distributed in the Distribution was received by any of the McKesson
shareholders as a creditor, employee, or in any capacity other than that of a shareholder of McKesson.

	 	41.	 Immediately before the Distribution, neither SpinCo, nor any of its domestic corporate subsidiaries, if any,

payment of its payables in anticipation of the Distribution. 

  

	 	44.	 If an investment credit determined under Section 46 was claimed with respect to any property transferred
by McKesson to SpinCo, the income tax liability for the taxable year in which investment credit property (including any building to which Section 47(d) applies) was transferred was or will be adjusted pursuant to Section 50(a)(1) or (a)(2)
(or Section 47, as in effect before amendment by Public Law 101-508, Title 11, 104 Stat. 1388, 536 (1990), if applicable) to reflect an early disposition of the property).

	 	53.	 Immediately after the Merger, Echo will be widely held and publicly traded. 

Corporate Business Purpose and Device 
  

	 	54.	 The Distribution will be carried out, in whole or substantial part, for the corporate business purposes
described in [•] (the “Business Purpose”). 

  

	 	55.	 The Business Purpose motivating the Distribution cannot be achieved through an alternative nontaxable
transaction that does not involve the distribution of stock of a SpinCo corporation and that is neither impractical nor unduly expensive. 

  

	 	56.	 Immediately after the Distribution, no director, officer or employee of McKesson or any of its direct or
indirect subsidiaries will also be a director, officer or employee of SpinCo or any of its direct or indirect subsidiaries, and there will be no plan or intention to cause (i) any director, officer or employee of McKesson or any of its direct
or indirect subsidiaries to also be a director, officer or employee of SpinCo or any of its direct or indirect subsidiaries or (ii) any director, officer or employee of SpinCo or any of its direct or indirect subsidiaries to also be a director,
officer or employee of McKesson or any of its direct or indirect subsidiaries. 

  

	 	57.	 No material reduction in the U.S. federal income tax liability of McKesson or SpinCo is reasonably expected to
result from the Distribution (other than as a result of the application of Sections 355 and 361). 

  

	 	58.	 The Distribution is not intended to be used principally as a device for the distribution of the earnings and
profits of McKesson, SpinCo or both (e.g., converting dividend income to capital gain, effecting a recovery of basis to reduce the amount of income taken into account). 

  
 9 

	 	59.	 Other than, in the case of SpinCo with respect to the Merger, there is no plan or intention to liquidate
McKesson or SpinCo, to merge McKesson or SpinCo, or to sell or otherwise dispose of the assets of McKesson or SpinCo after the Distribution, except in the ordinary course of business. 

 

	 	60.	 There will be no plan or intention by McKesson or SpinCo, or any party related to McKesson or SpinCo, to issue,
redeem or purchase any common stock of McKesson or SpinCo, other than (a) redemptions of McKesson common stock pursuant to the Exchange Offer and (b) purchases by McKesson of its common stock meeting the following requirements:
(i) there is a sufficient business purpose for the common stock purchase; (ii) the common stock to be purchased will be widely held; (iii) the common stock purchases will be made in the open market; and (iv) the aggregate amount
of common stock purchased will not to equal or exceed 20% of the outstanding common stock of McKesson. 

  

	 	61.	 Other than the Merger, the Distribution is not motivated in whole or in part by a business purpose to
facilitate the acquisition of common stock or assets of McKesson or SpinCo. 

  

	 	62.	 Other than (i) in the case of common stock or securities of McKesson or Echo, pursuant to the ordinary
course of public trading and (ii) in the case of common stock or securities of SpinCo, pursuant to the Merger, there is no plan or intention by any shareholder of McKesson or Echo to dispose of any of common stock or securities of McKesson or
SpinCo. 

  

	 	63.	 To the extent that any member of the McKesson SAG or SpinCo SAG will hold cash or other liquid or inactive
assets immediately following the Distribution, the amount of such assets so held will not exceed the reasonable needs of their respective businesses, and will be within industry norms. 

 

	 	64.	 No business conducted by the McKesson SAG, on the one hand, or by the SpinCo SAG, on the other hand, has or
will have as its principal function serving a business conducted by the other SAG. 

  

	 	65.	 The Distribution was not effected for the purpose of permitting any of the McKesson shareholders to avoid the
dividend provisions of the Code by the subsequent disposition of the common stock of McKesson or SpinCo and the retention of the common stock of the other. 

  

	 	66.	 Other than (i) trade account indebtedness created in the ordinary course of business through any
continuing transactions at terms comparable to those which could be obtained in an arm’s-length transaction and (ii) payables that arose or may arise under any of the Transaction Documents (including
for the avoidance of doubt, the Contribution Agreement), no intercorporate debt will exist between any member of the McKesson SAG and any member of the SpinCo SAG at the time of, or subsequent to, the Distribution. Other than pursuant to
(a) the Transaction Documents and (b) arrangements described in clause (i) of the preceding sentence, no contractual or other arrangements between the McKesson SAG, on the one hand, and the SpinCo SAG or Echo and its subsidiaries, on
the other hand, will survive the Distribution. 

  
 10 

	 	67.	 The receipt, if any, by McKesson shareholders of cash in lieu of fractional shares of Echo Common Stock in the
Merger will be solely for the purpose of avoiding the expense and inconvenience to Echo of issuing fractional shares and will not represent separately bargained-for consideration. It is intended that the total
cash consideration received by McKesson shareholders in the Merger will not exceed 1% of the total consideration that will be distributed to SpinCo shareholders in the Merger. It is intended that no McKesson shareholder will receive cash in lieu of
fractional shares in the Merger in an amount equal to or greater than the value of one full share of Echo Common Stock. 

 Code
Sections 355(d), 355(e) and 355(g) 
  

	 	68.	 McKesson has and will have no actual knowledge of any less-than-5%
shareholder of McKesson having acquired McKesson common stock by purchase (within the meaning of Section 355(d)(5)) during the Five-Year Period. 

  

	 	69.	 [Throughout the Five-Year Period, other than pursuant to the ordinary course of public trading, there were no
acquisitions of shares of McKesson common stock, including an acquisition resulting from an issuance of shares by McKesson, and there were no transfers to McKesson of equity interests in an entity (including a DRE), cash or cash items, marketable
stock or securities, debt of the transferor, or debt of the transferee not evidenced by a “security” as described in Section 351(d).] 

  

	 	70.	 For purposes of Section 355(d), immediately after the Distribution and the Merger, no person (determined
after applying Section 355(d)(7)) will hold common stock possessing 50% or more of the total combined voting power of all classes of McKesson common stock entitled to vote, or 50% or more of the total value of shares of all classes of McKesson
common stock, that will have been either (i) acquired by purchase (as defined in Section 355(d)(5) and (8), and by application of Treasury Regulations Section 1.355-6), or (ii) attributable
to distributions on McKesson common stock or securities that will have been acquired by purchase (as defined in Section 355(d)(5) and (8), and by application of Treasury Regulations Section 1.355-6),
in each case during the Five-Year Period (determined after applying Section 355(d)(6)). 

  

	 	71.	 For purposes of Section 355(d), immediately after the Distribution and the Merger, no person (determined
after applying Section 355(d)(7)) will hold common stock possessing 50% or more of the total combined voting power of all classes of SpinCo Common Stock entitled to vote, or 50% or more of the total value of shares of all classes of SpinCo
Common Stock, that will have been either (i) acquired by purchase (as defined in Section 355(d)(5) and (8), and by application of Treasury Regulations Section 1.355-6) during the Five-Year
Period 

  
 11 

	 	
(determined after applying Section 355(d)(6)), or (ii) attributable to distributions on McKesson common stock that will have been acquired by purchase (as defined in
Section 355(d)(5) and (8), and by application of Treasury Regulations Section 1.355-6), in each case during the Five-Year Period (determined after applying Section 355(d)(6)). 

 

	 	72.	 [Other than McKesson common stock acquired in the ordinary course of public trading, there will have been no
direct or indirect acquisition of an interest in the stock of McKesson or SpinCo during the two-year period prior to the Distribution.] 

 

	 	73.	 None of the Controlled Transfer, the Distribution or the Merger is, or will be, part of a plan or series of
related transactions (within the meaning of Treasury Regulations Section 1.355-7) pursuant to which one or more persons will acquire directly or indirectly equity representing a 50% or greater interest
(within the meaning of Section 355(d)(4)) in McKesson or SpinCo (or any predecessor or successor to any such corporation). 

  

	 	74.	 Immediately following the Merger, owners and former owners of McKesson Common Stock will, by reason of their
ownership of SpinCo Common Stock after the Distribution, own more than 50% of the issued and outstanding Common Stock of Echo, by vote and value. There is and, at the time of the Distribution, will be no plan or intention to reduce or otherwise
dilute the ownership interest in Echo (by voting power or value) of such owners and former owners of McKesson Common Stock. 

  

	 	75.	 Immediately after the Distribution, McKesson will not be a disqualified investment corporation (within the
meaning of Section 355(g)(2)). 

 The undersigned is authorized to make all the representations and certifications
set forth herein on behalf of McKesson and the management thereof, and is familiar with the matters set forth herein and has made such investigations of factual matters as the undersigned has deemed reasonably necessary for purposes of making the

we believe that all of the facts, representations and assumptions stated or referred to herein are consistent with the state of facts that will exist as of the Distribution Effective Time. We will immediately inform you if, after signing this
letter, we have reason to believe that any of the facts described herein, in the Merger Agreement, the Transaction Documents or the Applicable SEC Filings or any of the representations made in this letter are or have become untrue, incorrect or
incomplete in any respect. We understand that your opinion will be subject to certain limitations and qualifications, including that it may not be relied upon if any such facts or representations are not correct in all material respects.

MCK Merger Tax Opinion and the Echo Tax Opinion (the “Opinions”) to be delivered by MCK Tax Advisor and Echo Tax Counsel, pursuant to Section 5.2(b) and Section 5.3(b) of the Agreement and Plan of Merger (the
“Merger Agreement”),1 dated as of [•], between McKesson Corporation, a Delaware corporation (“McKesson”), [•], a Delaware corporation
(“SpinCo”) and HCIT Holdings, Inc., a Delaware corporation (“Echo”), you have requested certain representations from Echo. This officer’s certificate (“Officer’s Certificate”) is being
provided to you in response to that request. 
 Recognizing and acknowledging that [MCK Tax Advisor/Echo Tax Counsel] will rely on the
representations and covenants set forth in this Officer’s Certificate in delivering their respective Opinions, and that such Opinions will be based upon an assumption that all of the representations set forth herein are true, accurate and
complete without regard to any qualification for knowledge, belief, or otherwise, the undersigned officer of Echo hereby certifies and represents, on behalf of Echo (and its Affiliates, including, at all times after the Effective Time, SpinCo), that
the statements and representations contained herein are true, correct and complete in all respects as of the date hereof, and will be true, correct and complete in all material respects at the Effective Time (as if made as of the Effective Time) and
through the subsequent periods specified herein: 
 1. The facts relating to the Merger pursuant to the Merger Agreement as described in the
Applicable SEC Filings, insofar as those facts pertain to Echo and its Affiliates, are true, correct and complete in all material respects, and, insofar as those facts pertain to McKesson and its Affiliates and to SpinCo and its Subsidiaries, are,
to the knowledge of Echo, true, correct and complete in all material respects. The Merger will be consummated in accordance with the Merger Agreement, as amended (without waiver or modification of any provision thereof), and the descriptions
contained in the Applicable SEC Filings. 
 2. Other than with respect to (i) the Controlled Transfer, the Distribution and the
Merger and those agreements described or referred to in the Separation Agreement, the Merger Agreement and the Applicable SEC Filings and (ii) ordinary course commercial arrangements that were not entered into in contemplation of, or in
connection with, the Controlled Transfer, the Distribution or the Merger, there are no agreements, arrangements or understandings, either written or oral, between or among (a) Echo, its Affiliates or shareholders, on the one hand, and (b)
McKesson, its Affiliates or shareholders, on the other hand, concerning the Merger or otherwise. 
  

	1 	 Except where noted, each capitalized term used and not otherwise defined herein has the meaning ascribed to it
in the Merger Agreement, Separation and Distribution Agreement (the “Separation Agreement”) and other “Transaction Documents” (as defined in the Amended and Restated Limited Liability Company Agreement (the “LLC
Agreement”)). 

  
 2 

 3. The consideration to be received in the Merger by SpinCo’s shareholders was
determined by arm’s length negotiations between the Echo Shareholders and the management of McKesson. 
 4. The Merger will be effected
for the bona fide business purposes set forth in the Applicable SEC Filings. 
 5. The Merger will be consummated in compliance with
the Merger Agreement. Pursuant to, and in connection with, the Merger, at the Effective Time, (i) SpinCo will merge with and into Echo and (ii) no holder of SpinCo Common Stock will receive in exchange for SpinCo Common Stock, directly or
indirectly, any consideration other than Echo Common Stock, and cash in lieu of fractional shares of Echo Common Stock, as described in Section 3.3(b) of the Merger Agreement. 

6. The fair market value of the Echo Common Stock and cash in lieu of fractional shares received by each SpinCo shareholder will be
approximately equal to the fair market value of the SpinCo Common Stock surrendered in exchange therefor. 
 7. The receipt, if any, by
SpinCo shareholders of cash in lieu of fractional shares of Echo Common Stock in the Merger will be solely for the purpose of avoiding the expense and inconvenience to Echo of issuing fractional shares and will not represent separately bargained-for consideration. It is intended that the total cash consideration received by SpinCo shareholders in the Merger will not exceed 1% of the total consideration that will be distributed to SpinCo
shareholders in the Merger. It is intended that no SpinCo shareholder will receive cash in lieu of fractional shares in the Merger in an amount equal to or greater than the value of one full share of Echo Common Stock. 

8. Neither Echo nor any person related to Echo as defined in Treasury Regulations
Section 1.368-1(e)(4)2 (an “Echo Related Person”) has any plan, intention, obligation, agreement or understanding to, and will not in
connection with the Merger, directly or indirectly, for its own account, redeem or repurchase (including by derivative transactions such as an equity swap which would have the economic effect of an acquisition) any of the Echo Common Stock issued to
shareholders of SpinCo in the Merger except to the extent permitted by the Tax Matters Agreement. 
 9. There is no plan or intention to pay
dividends or distributions after the consummation of the Merger to the former shareholders of SpinCo by Echo other than dividends or distributions made to all holders of Echo Common Stock. 

10. The holders of SpinCo Common Stock will have no dissenters’ or appraisal or similar rights in the Merger. 

 
  

	2 	 Unless otherwise noted, all Section references herein refer to the Internal Revenue Code of 1986, as amended
(the “Code”), or to the Treasury Regulations promulgated thereunder. 

  
 3 

 11. Following the consummation of the Merger, Echo will continue the conduct of
SpinCo’s historic business or use a significant portion of SpinCo’s historic business assets in a business. For this purpose, Echo will be treated as holding all of the businesses and assets of (i) SpinCo and (ii) its Qualified
Group.3 
 12. Except for transactions or transfers described in
Section 368(a)(2)(C) or Treasury Regulations Section 1.368-2(k), Echo has no plan or intention to (in each case following the consummation of the Merger): (i) liquidate; (ii) cause itself to be
treated other than as a corporation for U.S. federal income tax purposes; (iii) merge with or into another corporation; or (iv) sell, exchange, distribute or otherwise dispose of any of its assets except for dispositions in the ordinary
course of its business. 
 13. Except as otherwise provided in the Merger Agreement, Echo will bear its own expenses, if any, incurred in
connection with or as part of the Merger. Echo has not paid and will not pay, directly or indirectly, any expenses (including transfer taxes) incurred by any shareholder of SpinCo in connection with or as part of the Merger or any related
transactions. Except as contemplated by the Separation Agreement, Echo has not agreed to assume, nor will it directly or indirectly assume, any other expense or other liability, whether fixed or contingent, of any shareholder of SpinCo. 

14. As of the Effective Time, there will be no indebtedness (other than intercompany receivables arising in the ordinary course of business)
existing between Echo (or any of its Subsidiaries) and SpinCo (or any of its Subsidiaries). 
 15. On the date of the Merger, the fair market
value of the assets of Echo will exceed the sum of its liabilities plus the liabilities, if any, to which its assets are subject. 
 16. Echo
is not a regulated investment company, a real estate investment trust or a corporation fifty percent (50%) or more of the value of whose assets are common stock and securities and eighty percent (80%) or more of the value of whose total assets are
assets held for investment (each, an “Investment Company”). For purposes of this representation, in making the 50% and 80% determinations under the preceding sentence: (i) stock and securities in any subsidiary corporation
shall be disregarded and the parent corporation shall be deemed to own its ratable share of the subsidiary’s assets and (ii) a corporation shall be considered a subsidiary if the parent owns fifty percent (50%) or more of the combined
voting power of all classes of stock entitled to vote or fifty percent (50%) or more of the total value of all classes of stock outstanding. In determining total assets there shall be excluded cash and cash items (including receivables), government
securities and assets acquired (through incurring indebtedness or otherwise) for purposes of ceasing to be an Investment Company. 
  

	3 	 A “Qualified Group” is one or more chains of corporations connected through stock ownership
with Echo but only if Echo is in control of at least one other corporation and each of the corporations (other than Echo) is controlled directly by one or more of the other corporations. If Echo’s Qualified Group owns an interest in a
partnership, Echo will be treated as owning a proportionate share of SpinCo business assets used in a business of that partnership. Echo will be treated as conducting a business of any partnership in which members of Echo’s Qualified Group own,
in the aggregate, at least a twenty percent (20%) interest in profits and capital and have active and substantial management functions as a partner with respect to that partnership business. 

  
 4 

 17. None of the compensation received or to be received by any employee or independent
contractor of SpinCo who is also a shareholder of SpinCo is or will be separate consideration for any of their SpinCo Common Stock to be surrendered in the Merger. None of the Echo Common Stock (or cash in lieu of fractional shares of Echo Common
Stock) to be received in connection with the Merger by any shareholder of SpinCo who is also an employee or independent contractor of SpinCo is or will be separate consideration for any employment, consulting or similar arrangement. Any compensation
paid or to be paid to any shareholder of SpinCo who will be an employee or independent contractor of or perform advisory services for Echo, SpinCo or any affiliate thereof after the consummation of the Merger, will be determined by bargaining at
arm’s length. 
 18. Echo is not under the jurisdiction of a court in a title 11 or similar case within the meaning of
Section 368(a)(3)(A). 
 19. Neither Echo nor, after the Merger, SpinCo, will take any position on any federal, state or local income or
franchise tax return or take any other tax reporting position that is inconsistent with the treatment of the Merger as a reorganization within the meaning of Section 368 or any of the foregoing representations. 

20. Neither Echo nor any of its Subsidiaries is or has been a United States real property holding corporation within the meaning of
Section 897(c)(2). 
 The undersigned is authorized to make all the representations and certifications set forth herein on behalf of
Echo and the management thereof, and is familiar with the matters set forth herein and has made such investigations of factual matters as the undersigned has deemed reasonably necessary for purposes of making the representations and statements
herein. We understand that you will rely on this letter in rendering your opinion as to certain U.S. federal income tax consequences of the Controlled Transfer, the Distribution and the Merger. As of the date hereof, we believe that all of the
facts, representations and assumptions stated or referred to herein are consistent with the state of facts that will exist as of the Effective Time. We will immediately inform you if, after signing this letter, we have reason to believe that any of
the facts described herein, in the Merger Agreement, the Transaction Documents or the Applicable SEC Filings or any of the representations made in this letter are or have become untrue, incorrect or incomplete in any respect. We understand that your
opinion will be subject to certain limitations and qualifications, including that it may not be relied upon if any such facts or representations are not correct in all material respects.
