OPTION TO ENTER INTO A PURCHASE AGREEMENT

Option to Purchase. Change Solutions (or any Subsidiary of any Echo Party that it designates) is hereby granted an option to purchase, at its election, all of the issued and outstanding capital stock of Echo Connect Holdings (the “Option”) on the terms set forth herein.

Exercise of Option. After the closing of the transactions contemplated by the Contribution Agreement (the “Closing”) and through March 1, 2022 (the “End Date”), Change Solutions may exercise the Option at any time MCK owns (directly or indirectly) less than 5% of the equity securities in the Company (the “Echo Option Trigger”). Change Solutions (or any Subsidiary of any Echo Party that it designates) may exercise the Option by delivering written notice (the “Option Notice”) to the Echo Shareholders and Echo Connect Holdings of its intent to exercise the Option.

Option Mechanics. Within 20 Business Days of its receipt of the Option Notice, Echo Connect Holdings and the Echo Shareholders will deliver to Change Solutions (or any Subsidiary of any Echo Party that it designates) a purchase agreement (the “Echo Connect Purchase Agreement”) consistent with the terms set forth herein, which Echo Connect Holdings, the Echo Shareholders and the Echo Parties (or any designated Subsidiary of the Echo Parties) hereby covenant and agree to execute as soon as reasonably practical.

Expiration of the Option. In the event that the End Date shall have occurred with no Echo Option Trigger having occurred or no Option Notice having been delivered pursuant to the terms hereof, the Option shall expire and be null and void and this Agreement shall terminate without further action by the parties hereto at the End Date, subject to Section 15, unless otherwise extended in writing by each of the parties hereto.

Option Purchase Price. In consideration of its acquisition of all of the issued and outstanding capital stock of Echo Connect Holdings pursuant to the Echo Connect Purchase Agreement, the Echo Connect Purchase Agreement will provide that Change Solutions (or any Subsidiary of any Echo Party that it designates), will pay to the Echo Shareholders at the closing under the Echo Connect Purchase Agreement an aggregate amount equal to (i) $1.00 plus (ii) the product of (A) (y) the estimated cumulative EBITDA for the 12-month period ended at the end of the most recent calendar month preceding the date of delivery of the Option Notice to the Echo Shareholders and Echo Connect Holdings (the “Trailing 12-month EBITDA”) of Echo Connect Holdings and its Subsidiaries as of the closing of the Echo Connect Purchase Agreement less (z) $14,269,000 multiplied by (B) twelve (12) (the “Purchase Price”). The Purchase Price will not be subject to an adjustment for cash, working capital or debt, but will contain a customary post-closing true-up of the estimated Trailing 12-month EBITDA compared against the actual Trailing 12-month EBITDA consistent with that set forth in Section 2.02 of the Contribution Agreement (mutatis mutandis). Notwithstanding the first sentence of this Section 5, in the event the Trailing 12-month EBITDA of Echo Connect Holdings and its Subsidiaries as of the closing of the Echo Connect Purchase Agreement is less than or equal to $14,269,000, the Purchase Price will be $1.00. “EBITDA” means with respect to Echo Connect Holdings and its Subsidiaries, “EBITDA” as calculated in the Credit Agreement, dated as of March 1, 2017, among Change Healthcare Intermediate Holdings, LLC, a Delaware limited liability company, Change Healthcare Holdings, LLC, a Delaware limited liability company, certain subsidiaries of the Parent Borrower, as Borrowers and Guarantors (each as defined therein), the Lenders (as defined therein) party thereto from time to time, Bank of America, N.A., as Administrative Agent, Collateral Agent, Swing Line Lender and L/C Issuer and the other parties party thereto (the “Credit Agreement”) as further adjusted for (i) any synergies resulting from Echo Connect Holdings and its Subsidiaries being integrated with Change Solutions (or any Subsidiary of any Echo Party that it designates), (ii) any run rate adjustments for cost actions already taken during the relevant period, (iii) any direct acquisition costs, such as third-party due diligence, legal and advisory costs and (iv) any run rate adjustments for acquisitions which occurred during the relevant period.

Limited Terms of the Echo Connect Purchase Agreement. The only representations and warranties given by the Echo Shareholders in the Echo Connect Purchase Agreement will be those related to organization (if applicable), authority, noncontravention of organizational documents, law or material agreements of the Person making such representation or warranty, title (other than customary permitted liens) and no brokers. Such representations and warranties will be made by each Echo Shareholder on a several (and not joint) basis solely as to itself. The Echo Connect Purchase Agreement will not contain any indemnification obligations on the part of any party, and the equity securities will be sold on an “as is, where is” basis (subject only to the representations and warranties set forth above) and the Echo Parties (and any of their designees) shall acknowledge that they have not relied on any representation or warranty other than as set forth in the Echo Connect Purchase Agreement.

Representations of the Echo Shareholders and the Connect Parties. Each Echo Shareholder and each Connect Party (severally as to itself and not jointly) hereby represents and warrants to the Echo Parties that (i) this Agreement is a valid and binding agreement of such Person, enforceable against it in accordance with its terms and (ii) as of the date hereof, the Echo Shareholders are, and as of the date of the consummation of the Closing of the transactions under the Echo Connect Purchase Agreement will be, the only holders of capital stock in Echo Connect Holdings (other than any Person who receives capital stock in Echo Connect Holdings pursuant to employee incentive arrangements and becomes subject to the Echo Connect Stockholders Agreement (as defined below)).

Covenants of the Echo Shareholders and the Connect Parties.

From the Closing through the End Date (or, if the Option is properly exercised hereunder, the effective execution of the Echo Connect Purchase Agreement by all of the parties contemplated thereby pursuant to the terms hereof), the Connect Parties will (i) not sell, convey, transfer or encumber any material asset (or equity securities) of the Connect Parties outside the ordinary course of business, other than to secure indebtedness for borrowed money; provided that any encumbrance of any equity securities of the Connect Parties to secure indebtedness for borrowed money shall be made subject to the Option in all respects; and (ii) not permit any funds to leave the Connect Parties for the benefit of any Echo Shareholder other than (1) any indemnification or advancement payments owed under its organizational agreements, any payments in accordance with any equity incentive plan or any payments pursuant to applicable law or court order or (2) any payments in the ordinary course of business provided, any such payments described in clause (2) made for the benefit of any Echo Shareholder must be entered into on arm’s length terms and in the ordinary course of business for the purchase of materials, supplies, goods, services (excluding any employment agreements), equipment or other assets that are generally available for purchase by business entities in the Connect Parties’ line of business on substantially similar terms from non-affiliated suppliers or providers.

From the Closing through the End Date (or, if the Option is properly exercised hereunder, the effective execution of the Echo Connect Purchase Agreement), each Echo Shareholder agrees (as to itself) not to transfer any capital stock in Echo Connect Holdings, other than a transfer permitted under Section 4.1 of the Echo Connect Stockholders Agreement (as defined below) and in accordance with Section 10.

Publicity and Confidentiality. The Echo Parties, the Connect Parties and each Echo Shareholder shall keep confidential this Agreement, the transactions contemplated hereby and any non-public information relating to the Connect Parties, Echo, the Company or any of their respective Subsidiaries and shall not disclose, issue any press release or otherwise make any public statement in connection therewith (other than as may be necessary to monitor, increase or decrease its investment in the Company) without the prior written consent of the Sponsors (not to be unreasonably withheld); provided, that such Echo Parties, the Connect Parties and each Echo Shareholder may disclose any such information (i) as has become generally available to the public, (ii) to its employees and attorneys, accountants, consultants and other professional advisers who need to know such information, including to the extent necessary to obtain their services in connection with monitoring its investment in the Connect Parties, Echo, the Company or any of their respective Subsidiaries, and agree to keep it confidential, (iii) to the extent required in order to comply with reporting obligations to its direct or indirect partners, members, or other equity holders (including the employees and professional advisors of such equity holders)

No Assignment; Additional Echo Shareholders. No party hereto will have the right to sell, transfer, assign or pledge all or any portion of its interest in this Agreement without the prior written approval of the other parties hereto; provided, however, that each Echo Shareholder may sell, transfer, assign or pledge all or any of its rights hereunder in connection with any Transfer permitted under the Echo Connect Stockholders Agreement, provided that such transferee executes a joinder to this Agreement as a party hereto. Pursuant to the terms of the Echo Connect Stockholders Agreement and prior to expiration of this Agreement pursuant to Section 4, Echo Connect Holdings will not issue any additional Equity Interests (as defined in the Echo Connect Stockholders Agreement) to any Person that has not executed and delivered a joinder to this Agreement as a party hereto.

No waiver by any party hereto of any breach or violation of, default under or inaccuracy in any representation, warranty, covenant or agreement hereunder, whether intentional or not, will be deemed to extend to any prior or subsequent breach, violation, default of or inaccuracy in any representation, warranty, covenant or agreement hereunder or affect in any way any rights arising by virtue of any prior or subsequent occurrence.
