(15) Section 5.16 of the Agreement shall be amended and restated to read in its entirety as follows:

“Section 5.16. Employee Matters.

(a) MCK and Echo Holdco shall cooperate in good faith following the date hereof to identify the MTI Participating Employees (including those providing shared services and working at a corporate level) in a manner intended to be consistent (along with the Transition Services Agreements) with the “stand-alone cost model” included in Section 5.16 of the MCK Disclosure Schedule (the “Cost Model”); provided, that the Parties hereby agree that (i) the Additional Agreed Employees shall be deemed to be MTI Participating Employees for all purposes under this Agreement (including, for the avoidance of doubt, Section 5.16(f)) and (ii) the salaries, benefits and other on-going costs associated with the Company’s employment or engagement of the Additional Agreed Employees shall not be taken into account for purposes of determining whether the MTI Participating Employees have been identified in a manner consistent with the Cost Model.

(b) MCK shall use its commercially reasonable efforts to cause all of its or its Subsidiaries’ employees who are identified as MTI Participating Employees pursuant to Section 5.16(a), other than the MTS Finance Transition Services Employees who shall be transferred pursuant to Section 5.16(d), to be employed or engaged by a MCK Contributed Entity prior to the Closing, such that such MTI Participating Employees are transferred to the Company at the Closing.

6

(c) Following the Closing, MCK and the Company will establish a Finance Separation Steering Committee (“FSSC”) made up of two representatives from each of MCK and the Company, which representatives will be senior-level accounting and finance executives with decision-making authority around the matters within scope for the FSSC, provided that representatives of the Company shall not include current directors, officers, consultants or employees of MCK, its subsidiaries, or its Affiliates, and provided further that any individual who serves on the FSSC may be replaced or removed at any time by the party that he or she represents on the FSSC. The initial MCK representatives on the FSSC will be Erin Lampert and Sundeep Reddy and the initial Company representatives on the FSSC will be Randy Giles and Dennis Robbins. Either party may replace any member designated by such party to the FSSC upon reasonable prior notice to the other party. As soon as practicable following Closing, the FSSC will review the employees of MCK or its Subsidiaries providing Core MTS Finance Services and identify the MTS Finance Transition Services Employees, who, based on the FSSC’s reasonable judgment, shall together, be able to provide reasonably necessary and adequate finance and accounting services to the Company following the Closing comparable to those provided to the Core MTS Business immediately prior to the Closing, and who shall subsequently receive offers of employment from the Company. The FSSC will meet regularly to provide oversight of the Finance Process Separation, establish timelines and resolve issues. The FSSC will also receive updates on the Company’s financial system migration, anticipated compliance with SOX and related securities laws, and efforts to achieve synergies from the finance organization and will work together to resolve any needs related to finance systems access by the Company’s offshore contractors in connection with such synergy realization efforts. Any such access will be strictly for the purpose of performing accounting and finance functions for the Core MTS Business and shall be consistent with MCK’s and the Company’s security, privacy and confidentiality requirements. If any MTS Finance Transition Services Employees are terminated involuntarily by MCK, and such termination is consented to by the Company (which consent shall not be unreasonably withheld, conditioned or delayed), the Company will be responsible for such MTS Finance Transition Services Employee’s severance costs.

(d) Following the Closing, MCK and the Company will use their reasonable best efforts to transfer the employment of any MTS Finance Transition Services Employees to the Company on or before the Finance Separation Date and in a manner that is consistent with the Cost Model; provided, that to the extent MTS Finance Transition Services Employees who are providing services to the Company pursuant to the Transition Services Agreements are transferred to the Company, the services fees under the Transition Services Agreement shall be reduced by the amount of the cost of the MTS Finance Transition Services Employees being so transferred. In furtherance of the foregoing, the Company agrees that, from time to time, it will make offers of employment to the applicable MTS Finance Transition Services Employees then employed by MCK or one of its Subsidiaries within 10 days of completion of a Finance Process Separation phase; provided, that the Company shall make offers of employment to all MTS Finance Transition Services Employees then employed by MCK or its Subsidiaries no later than the Finance Separation Date.

7

(e) MCK and Echo Holdco agree to cooperate in good faith between the date hereof and such date (the “Plan Determination Date”) that allows MCK to reasonably set up Mirror Plans (as defined below) necessary to determine the appropriate employee benefits plans (the “New Company Benefit Plans”) for Company Employees with the intention that similarly situated Echo Participating Employees and MTI Participating Employees will receive substantially comparable benefits to the other by January 1, 2018, which may include establishment of plans at the applicable MCK Contributed Entity level effective January 1, 2017 (“New Subsidiary Plans”). If MCK and Echo Holdco fail to mutually agree upon the New Company Benefit Plans by the Plan Determination Date, MCK shall use its commercially reasonable efforts to cause the applicable MCK Contributed Entity to establish “mirror” benefit plans for each material health and welfare and nonqualified deferred compensation plan that covers the MTI Participating Employees as of the date hereof, effective starting no later than the Closing Date (such plans or the New Subsidiary Plans, as applicable, the “Mirror Plans”). Each Mirror Plan is intended to be substantially similar to the corresponding MCK plan. To the extent the Mirror Plans are “spinoffs” of MCK Plans that are funded through a rabbi trust, MCK shall provide sufficient assets (or access to such assets) to the Company to cover any existing liabilities as of Closing associated with such Mirror Plans. The expenses incurred in connection with setting up such New Company Benefit Plans or Mirror Plans, as applicable, shall be considered a Shared Transaction Expense.

(f) For a period of at least one year following the Closing Date, the Company shall provide (x) each Echo Participating Employee and (y) each MTI Participating Employee, in each case who is employed by the Company or one of its Subsidiaries immediately after the Closing Date or the employment transfer date (the “Employment Transfer Date”), if after the Closing Date (collectively, the “Company Employees”), with base salary or wage rate at least equal to the base salary or wage rate provided to such Company Employee immediately prior to the Closing Date. In addition, the Company shall provide that each MTI Participating Employee shall (i) be eligible for an annual cash bonus opportunity for fiscal year 2018 comparable to such employee’s cash bonus opportunity for fiscal year 2017 as an employee of MCK and consistent with the approvals of the Management Selection Committee prior to Closing and (ii) receive additional compensation from the Company that is consistent with the approvals of the Management Selection Committee prior to Closing and intended to be an amount sufficient to replace the fair market value of the unvested MCK equity and non-equity awards held by such MTI Participating Employee that were cancelled in connection with such employee’s transfer to the Company, determined as of the Closing Date or the Employment Transfer Date, as the case may be; provided, that the final determinations of annual cash bonuses and additional compensation shall be at the discretion of the board of directors of the Company. With respect to all benefit plans of the Company or its Subsidiaries in which Company Employees participate after the Closing Date (the “Company Plans”) (including any vacation, paid time-off and severance plans), for all purposes (but not for benefit accrual under any defined benefit plan or vesting under any equity compensation plan), including determining eligibility to participate, level of benefits, vesting, benefit accruals and early retirement subsidies, each Company Employee’s service with Echo Holdco or MCK, as

8

applicable (as well as service with any predecessor employer to the extent service with the predecessor employer is recognized by Echo Holdco or MCK, as applicable) shall, to the extent permitted by applicable Law and the Company Plan, be treated as service with the Company; provided, however, that such service need not be recognized to the extent that such recognition would result in any duplication of benefits for the same period of service.

(g) The Company, Echo Holdco and MCK shall use reasonable best efforts between the date of this Agreement and Closing to determine appropriate management equity incentive plans for the employees of the Company post-Closing.

(h) The Company shall pay to eligible MTI Participating Employees who have been transferred to the Company on or before the payment date all amounts payable to such MTI Participating Employees under the MIP in respect of fiscal year 2017 (“MIP Liabilities”) no later than June 30, 2017, provided that: (i) for the period from April 1, 2016 through February 28, 2017, payment will be subject to company and personal modifiers set by MCK (including MCK managers), (ii) for the period from March 1, 2017 through March 31, 2017, payment will be calculated at target, without application of any modifier; provided, further, that eleven-twelfths (11/12ths) of the MIP Liabilities shall be included as current liabilities in the calculation of MCK Net Working Capital.

(i) The Company shall pay to eligible MTI Participating Employees who are transferred to the Company on or before the payment date, all amounts payable to such MTI Participating Employees under the fiscal years 2015 – 2017 cycle under the LTIP no later than June 30, 2017 (“LTIP Liabilities”); provided, that all of the LTIP Liabilities shall be included as current liabilities in the calculation of MCK Net Working Capital.

(j) Prior to the Finance Separation Date, MCK and its Subsidiaries shall use reasonable best efforts to limit access to the Company’s finance and accounting data, processes and other confidential information, by the employees, officers, service providers, and consultants of MCK and its Subsidiaries who are not MTS Finance Transition Services Employees. Notwithstanding anything in this Agreement or the Transaction Documents, the Parties acknowledge and agree that the Company will be responsible for all third party expenses (including capex) relating to revenue convergence for the Core MTS Business. MCK will be responsible for revenue convergence costs and all other operative expense, capex and third party costs with respect to business retained by MCK. On and after such time that the Company and its Subsidiaries are required to comply with SOX, to the extent that any systems, processes or procedures of MCK and its Subsidiaries cause the Company and its Subsidiaries to have a material weakness under SOX, MCK and its Subsidiaries will take reasonable best efforts, at their sole expense, to remedy any such non-compliance. The parties acknowledge that reasonable cooperation among the parties may be required to remedy such non-compliance.

(k) Notwithstanding anything in Section 5.14, MCK and its Subsidiaries (other than the Company and its Subsidiaries) shall not solicit for employment any MTS Finance Transition Services Employee who was employed at the level 109 and above from the Closing until one year from such employee’s Finance Separation Date, unless such employee (i) ceases to be an employee of the Company or their respective Subsidiaries, by

9

reason of voluntary termination of employment, at least one month prior to such action by such soliciting Person or (ii) is terminated involuntarily by the Company, provided that the foregoing provision will not prevent MCK or its Subsidiaries from employing any MTS Finance Transition Services Employee who contacts the soliciting Person on his or her own initiative without any direct or indirect solicitation by, or encouragement from, such soliciting Person; provided further, that the publication of advertisements in newspapers and/or electronic media of general circulation (including advertisements posted on the Internet) will not be deemed a violation of this Section 5.16(k).”

(16) A new Section 5.20 is added to the Agreement as follows:

“Section 5.20 Customer Transition Costs. Notwithstanding any other provision of this Agreement, after the Closing, MCK shall submit to the Company payments totaling one million dollars ($1,000,000.00) (the “Transition Payment”) as payment for the costs that the Company may incur transitioning the Company’s obligations related to the McKesson EIS Business under customer agreements to non-Company entities, and/or terminating the portion of each customer agreement that relates to McKesson EIS Business. MCK shall pay the Transition Payment in twelve equally monthly installments of eighty three thousand, three hundred and thirty-three dollars and thirty-three cents ($83,333.33 starting the first day of the month following the Closing). Making the Transition Payment shall be MCK’s sole obligation with respect to payment to the Company for any costs associated with the customer transition described in this Section 5.20.”

B. No Breach. The parties hereto agree that the adoption of the 3-Year Position (as defined in the Letter Agreement) by the Company pursuant to and in accordance with the Letter Agreement will not constitute a breach of the Contribution Agreement by any party to the Contribution Agreement.

C. Authority. Each party hereto represents and warrants that it has all requisite corporate or limited liability company, as applicable, power and authority to execute and deliver this Amendment and to perform its obligations hereunder; and the execution, delivery and performance of this Amendment has been duly authorized by all necessary corporate or limited liability company, as applicable, action.
