As promptly as practicable, the ITR Entity and the
Corporate Taxpayer shall agree on a replacement IPO Date Asset Disclosure Letter that reflects any adjustments necessary as a result of the IPO. 

  
 -9- 

 Section 2.2. Tax Benefit Schedule. 

(a) Tax Benefit Schedule. Within 90 calendar days after the filing of the United States federal income tax return of the Corporate
Taxpayer for any Taxable Year in which there is a Realized Tax Benefit or Realized Tax Detriment, the Corporate Taxpayer shall provide to the ITR Entity a schedule showing, in reasonable detail, the calculation of the Realized Tax Benefit or
Realized Tax Detriment for such Taxable Year (a “Tax Benefit Schedule”). The Tax Benefit Schedule will become final as provided in Section 2.3(a) and may be amended as provided in Section 2.3(b) (subject to the procedures
set forth in Section 2.3(b)). 
 (b) Applicable Principles. Subject to Section 3.3(a), the Realized Tax Benefit or Realized
Tax Detriment for each Taxable Year is intended to measure the decrease or increase in the actual liability for Taxes of the Corporate Taxpayer for such Taxable Year attributable to the NOLs, the Pre-IPO Basis
Adjustments and Imputed Interest, determined using a “with and without” methodology. For the avoidance of doubt, the actual liability for Taxes will take into account the deduction of the portion of the Tax Benefit Payment that must be
accounted for as interest under the Code based upon the characterization of Tax Benefit Payments as additional consideration payable by the Corporate Taxpayer for the acquisition of the shares or assets of the GA Corporate Member or the HF Corporate
Member in connection with the Reorganization. Carryovers or carrybacks of any Tax item attributable to the NOLs, the Pre-IPO Basis Adjustment and Imputed Interest shall be considered to be subject to the rules
of the Code and the Treasury Regulations or the appropriate provisions of U.S. state and local income and franchise tax law, as applicable, governing the use, limitation and expiration of carryovers or carrybacks of the relevant type. If a carryover
or carryback of any Tax item includes a portion that is attributable to the NOLs, the Pre-IPO Basis Adjustment or Imputed Interest and another portion that is not, such portions shall be considered to be used
in accordance with the “with and without” methodology. 
 Section 2.3. Procedures, Amendments.  

(a) Procedure. Every time the Corporate Taxpayer delivers to the ITR Entity an applicable Schedule under this Agreement, including any
Amended Schedule delivered pursuant to Section 2.3(b), but excluding any Early Termination Schedule or amended Early Termination Schedule, the Corporate Taxpayer shall also (x) deliver to the ITR Entity schedules and work papers, as
determined by the Corporate Taxpayer or requested by the ITR Entity, providing reasonable detail regarding the preparation of the Schedule and (y) allow the ITR Entity reasonable access at no cost to the appropriate representatives at the
Corporate Taxpayer, as determined by the Corporate Taxpayer or requested by the ITR Entity, in connection with a review of such Schedule. Without limiting the application of the preceding sentence, each time the Corporate Taxpayer delivers to the
ITR Entity a Tax Benefit Schedule, in addition to the Tax Benefit Schedule duly completed, the Corporate Taxpayer shall deliver to the ITR Entity the Corporate Taxpayer Return, the reasonably detailed calculation by the Corporate Taxpayer of the
Hypothetical Tax Liability, the reasonably detailed calculation by the Corporate Taxpayer of the actual Tax liability, as well as any other work papers as determined by the Corporate Taxpayer or requested by the ITR Entity. An applicable Schedule or
amendment thereto shall become final and binding on all parties 30 calendar days from the first date on which the ITR Entity has received the applicable Schedule or amendment thereto unless the ITR Entity (i) within 30 calendar days after
receiving an applicable Schedule or amendment thereto, provides the Corporate Taxpayer with notice of a material objection to such Schedule (“Objection Notice”) 

  
 -10- 

 
made in good faith or (ii) provides a written waiver of such right of any Objection Notice within the period described in clause (i) above, in which case such Schedule or amendment
thereto becomes binding on the date the waiver is received by the Corporate Taxpayer. If the parties, for any reason, are unable to successfully resolve the issues raised in the Objection Notice within 30 calendar days after receipt by the Corporate
Taxpayer of an Objection Notice, the Corporate Taxpayer and the ITR Entity shall employ the reconciliation procedures as described in Section 7.9 of this Agreement (the “Reconciliation Procedures”). 

(b) Amended Schedule. The applicable Schedule for any Taxable Year may be amended from time to time by the Corporate Taxpayer
(i) in connection with a Determination affecting such Schedule, (ii) to correct inaccuracies in the Schedule identified as a result of the receipt of additional factual information relating to a Taxable Year after the date the Schedule was
provided to the ITR Entity, (iii) to comply with the Expert’s determination under the Reconciliation Procedures, (iv) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to a
carryback or carryforward of a loss or other tax item to such Taxable Year, or (v) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to an amended Tax Return filed for such Taxable Year
(any such Schedule, an “Amended Schedule”). The IPO Date Asset Disclosure Letter shall be appropriately amended by the ITR Entity and the Corporate Taxpayer to the extent that, as a result of a Determination the Corporate Taxpayer
is required to calculate its Tax liability in a manner inconsistent with the IPO Date Asset Disclosure Letter. 
 ARTICLE III 

TAX BENEFIT PAYMENTS 

Section 3.1. Payments. 

(a) Payments. Within five (5) calendar days after a Tax Benefit Schedule delivered to the ITR Entity becomes final in accordance
with Section 2.3(a), the Corporate Taxpayer shall pay to the ITR Entity for such Taxable Year the Tax Benefit Payment determined pursuant to Section 3.1(b). Each such Tax Benefit Payment shall be made by wire transfer of immediately
available funds to the bank account previously designated by the ITR Entity to the Corporate Taxpayer or as otherwise agreed by the Corporate Taxpayer and the ITR Entity. For the avoidance of doubt, no Tax Benefit Payment shall be made in respect of
estimated tax payments, including, without limitation, federal estimated income tax payments. Notwithstanding anything herein to the contrary, in no event shall the aggregate Tax Benefit Payments (including Tax Benefit Payments previously made
pursuant to the Original Agreement) (excluding any amount accounted for as interest under the Code) exceed $96,000,000 in respect of the Corporate Taxpayer, $63,000,000 in respect of the GA Corporate Member, and $53,000,000 in respect of the HF
Corporate Member. 
 (b) A “Tax Benefit Payment” means an amount, not less than zero, equal to the sum of the Net Tax
Benefit and the Interest Amount. For the avoidance of doubt, for Tax purposes, the Interest Amount shall not be treated as interest but shall instead be treated as additional consideration for the acquisition of the assets or stock of the GA
Corporate Member, the HF Corporate Member in connection with the IPO and the Reorganization, unless otherwise required by law. Subject to Section 3.3(a), the “Net Tax Benefit” for a Taxable Year shall be an amount

  
 -11- 

 
equal to the excess, if any, of 85% of the Cumulative Net Realized Tax Benefit as of the end of such Taxable Year over the total amount of payments previously made under this Section 3.1
(excluding payments attributable to Interest Amounts); provided, for the avoidance of doubt, that the ITR Entity shall not be required to return any portion of any previously made Tax Benefit Payment. The “Interest Amount”
shall equal the interest on the Net Tax Benefit calculated at the Agreed Rate from the due date (without extensions) for filing the Corporate Taxpayer Return with respect to Taxes for such Taxable Year until the Payment Date. Notwithstanding the
foregoing, for each Taxable Year ending on or after the date of a Change of Control, all Tax Benefit Payments shall be calculated by utilizing Valuation Assumptions (1) and (3), substituting in each case the terms “the closing date of a
Change of Control” for an “Early Termination Date.” 
 Section 3.2. No Duplicative Payments. It is intended that
the provisions of this Agreement will not result in duplicative payment of any amount (including interest) required under this Agreement. It is also intended that the provisions of this Agreement provide that Tax Benefit Payments are paid to the ITR
Entity pursuant to this Agreement. The provisions of this Agreement shall be construed in the appropriate manner to ensure such intentions are realized. 

Section 3.3. Pro Rata Payments; Coordination of Benefits With Other Tax Receivable Agreements. 

(a) Notwithstanding anything in Section 3.1 to the contrary, to the extent that the aggregate tax benefit of the Corporate Taxpayer’s
deduction with respect to the NOLs, the Pre-IPO Basis Adjustments, the Basis Adjustments or Imputed Interest under the Tax Receivable Agreements (as such terms are defined in each Tax Receivable Agreement) is
limited in a particular Taxable Year because the Corporate Taxpayer does not have sufficient taxable income, the limitation on the tax benefit for the Corporate Taxpayer shall be allocated among the Tax Receivable Agreements (and among all parties
eligible for payments thereunder) in proportion to the respective amounts of Realized Tax Benefits that would have been determined under the Tax Receivable Agreements if the Corporate Taxpayer had sufficient taxable income so that there were no such
limitation. 
 (b) If for any reason the Corporate Taxpayer does not fully satisfy its payment obligations to make all Tax Benefit Payments
due under the Tax Receivable Agreements in respect of a particular Taxable Year, then the Corporate Taxpayer and the ITR Entity agree that (i) the Corporate Taxpayer shall pay the same proportion of each Tax Benefit Payment due under each of
the Tax Receivable Agreements in respect of such Taxable Year, without favoring one obligation over the other, and (ii) no Tax Benefit Payment shall be made in respect of any Taxable Year until all Tax Benefit Payments in respect of prior
Taxable Years have been made in full. 
 (c) To the extent that the Corporate Taxpayer makes payments to the ITR Entity in respect of a
particular Taxable Year in an amount greater than the payments that should have been made in accordance with Section 3.3(b), then the ITR Entity shall be obligated to make payments to the parties to the other Tax Receivable Agreements (other
than the Corporate Taxpayer) in the amounts necessary so that each party to the Tax Receivable Agreements shall have received the amount that it would have received if all payments by the Corporate Taxpayer had been in accordance with
Section 3.3(b); provided, that the ITR Entity’s obligation to pay over to the parties to the other Tax Receivable Agreements amounts received from the Corporate Taxpayer pursuant to this Section 3.3(c) shall terminate on the
one year anniversary of the receipt by the ITR Entity of such amounts. 

  
 -12- 

 (d) The parties hereto agree that the parties to the Investors Tax Receivable Agreement
(Exchanges) and the parties to the Management Tax Receivable Agreement are expressly made third party beneficiaries of the provisions of this Section 3.3. 

ARTICLE IV 
 TERMINATION

 Section 4.1. Early Termination and Breach of Agreement. 

(a) The Corporate Taxpayer may terminate this Agreement with respect to all amounts payable to the ITR Entity at any time by paying to the ITR
Entity the Early Termination Payment; provided, that the Corporate Taxpayer may withdraw any notice to execute its termination rights under this Section 4.1(a) prior to the time at which any Early Termination Payment has been paid. Upon
payment of the Early Termination Payment by the Corporate Taxpayer, neither the ITR Entity nor the Corporate Taxpayer shall have any further payment obligations under this Agreement, other than for any (a) Tax Benefit Payment agreed to by the
Corporate Taxpayer and the ITR Entity as due and payable but unpaid as of the Early Termination Notice and (b) Tax Benefit Payment due for the Taxable Year ending with or including the date of the Early Termination Notice (except to the extent
that the amount described in this clause (b) is included in the Early Termination Payment). 
 (b) In the event that the Corporate
Taxpayer breaches any of its material obligations under this Agreement, whether as a result of failure to make any payment when due, failure to honor any other material obligation required hereunder or by operation of law as a result of the
rejection of this Agreement in a case commenced under the Bankruptcy Code or otherwise, then all obligations hereunder shall be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the date of
such breach and shall include, but not be limited to, (1) the Early Termination Payment calculated as if an Early Termination Notice had been delivered on the date of a breach, (2) any Tax Benefit Payment agreed to by the Corporate
Taxpayer and the ITR Entity as due and payable but unpaid as of the date of a breach with respect to any Taxable Year prior to the Taxable Year ending with or including the date of a breach, and (3) any Tax Benefit Payment due for the Taxable
Year ending with or including the date of a breach but reduced by any amount with respect to the portion of such Taxable Year beginning after the date of such breach taken into account for purposes of determining the amount due under clause
(1) of this sentence. Notwithstanding the foregoing, in the event that the Corporate Taxpayer breaches this Agreement, the ITR Entity shall be entitled to elect to receive the amounts set forth in clauses (1), (2) and (3) above or to seek
specific performance of the terms hereof. The parties agree that the failure to make any payment due pursuant to this Agreement within three months of the date such payment is due shall be deemed to be a breach of a material obligation under this
Agreement for all purposes of this Agreement, and that it will not be considered to be a breach of a material obligation under this Agreement to make a payment due pursuant to this Agreement within three months of the date such payment is due.

  
 -13- 

 
Notwithstanding anything in this Agreement to the contrary, it shall not be a breach of this Agreement if the Corporate Taxpayer fails to make any Tax Benefit Payment when due to the extent that
the Corporate Taxpayer has insufficient funds to make such payment; provided that the interest provisions of Section 5.2 shall apply to such late payment (unless the Corporate Taxpayer does not have sufficient cash to make such payment
as a result of limitations imposed by any credit agreement to which the Corporate Taxpayer or any of its Subsidiaries is a party, in which case Section 5.2 shall apply, but the Default Rate shall be replaced by LIBOR plus 300 basis points).

 Section 4.2. Early Termination Notice. 

(a) If the Corporate Taxpayer chooses to exercise its right of early termination under Section 4.1 above other than in connection with a
Change of Control or Subsequent IPO, the Corporate Taxpayer shall deliver to the ITR Entity notice of such intention to exercise such right (“Early Termination Notice”) and a schedule (the “Early Termination
Schedule”) specifying the Corporate Taxpayer’s intention to exercise such right and showing in reasonable detail the calculation of the Early Termination Payment for the ITR Entity. The Early Termination Schedule shall become final and
binding on all parties 30 calendar days from the first date on which the ITR Entity has received such Schedule or amendment thereto unless the ITR Entity (i) within 30 calendar days after receiving the Early Termination Schedule, provides the
Corporate Taxpayer with notice of a material objection to such Schedule made in good faith (“Material Objection Notice”) or (ii) provides a written waiver of such right of a Material Objection Notice within the period described
in clause (i) above, in which case such Schedule becomes binding on the date the waiver is received by the Corporate Taxpayer (the “Early Termination Effective Date”). If the parties, for any reason, are unable to successfully
resolve the issues raised in such notice within 30 calendar days after receipt by the Corporate Taxpayer of the Material Objection Notice, the Corporate Taxpayer and the ITR Entity shall employ the Reconciliation Procedures. 

(b) If the Corporate Taxpayer chooses to exercise its right of early termination under Section 4.1 above in connection with a Change of
Control or Subsequent IPO, any reference to 30 calendar days in Section 4.2(a) above shall instead be deemed to be 10 calendar days. 

Section 4.3. Payment upon Early Termination. 

(a) Within three calendar days after the Early Termination Effective Date, the Corporate Taxpayer shall pay to the ITR Entity an amount equal
to the Early Termination Payment. Such payment shall be made by wire transfer of immediately available funds to a bank account or accounts designated by the ITR Entity or as otherwise agreed by the Corporate Taxpayer and the ITR Entity. 

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

 ARTICLE V 

SUBORDINATION AND LATE PAYMENTS 

Section 5.1. Subordination. Notwithstanding any other provision of this Agreement to the contrary, any payment required to be made
by the Corporate Taxpayer under this Agreement shall rank subordinate and junior in right of payment to any principal, interest or other amounts due and payable in respect of any obligations in respect of indebtedness for borrowed money of the
Corporate Taxpayer and its Subsidiaries (“Senior Obligations”) and shall rank pari passu with all current or future unsecured obligations of the Corporate Taxpayer that are not Senior Obligations. 

Section 5.2. Late Payments by the Corporate Taxpayer. The amount of all or any portion of any Tax Benefit Payment or Early
Termination Payment not made to the ITR Entity when due under the terms of this Agreement shall be payable together with any interest thereon, computed at the Default Rate and commencing from the date on which such Tax Benefit Payment or Early
Termination Payment was due and payable. 
 ARTICLE VI 

NO DISPUTES; CONSISTENCY; COOPERATION 

Section 6.1. Participation in the Corporate Taxpayer’s and EBS’s Tax Matters. Except as otherwise provided herein, the
Corporate Taxpayer shall have full responsibility for, and sole discretion over, all Tax matters concerning the Corporate Taxpayer and EBS, including without limitation the preparation, filing or amending of any Tax Return and defending, contesting
or settling any issue pertaining to Taxes. Notwithstanding the foregoing, the Corporate Taxpayer shall notify the ITR Entity of, and keep the ITR Entity reasonably informed with respect to, the portion of any audit of the Corporate Taxpayer and EBS
by a Taxing Authority the outcome of which is reasonably expected to affect the rights and obligations of the ITR Entity under this Agreement, and shall provide to the ITR Entity reasonable opportunity to provide information and other input to the
Corporate Taxpayer, EBS and their respective advisors concerning the conduct of any such portion of such audit; provided, however, that the Corporate Taxpayer and EBS shall not be required to take any action that is inconsistent with
any provision of the LLC Agreement. 
 Section 6.2. Consistency. The Corporate Taxpayer and the ITR Entity agree to report and
cause to be reported for all purposes, including federal, state and local Tax purposes and financial reporting purposes, all Tax-related items (including, without limitation, the
Pre-IPO Basis Adjustments and each Tax Benefit Payment) in a manner consistent with that specified by the Corporate Taxpayer in any Schedule required to be provided by or on behalf of the Corporate Taxpayer
under this Agreement unless otherwise required by law. 
 Section 6.3. Cooperation. The ITR Entity shall (a) furnish to the
Corporate Taxpayer in a timely manner such information, documents and other materials as the Corporate Taxpayer may reasonably request for purposes of making any determination or computation necessary or appropriate under this Agreement, preparing
any Tax Return or contesting or defending any audit, examination or controversy with any Taxing Authority, (b) make itself available to the Corporate Taxpayer and its representatives to provide explanations of documents and materials

  
 -15- 

 
and such other information as the Corporate Taxpayer or its representatives may reasonably request in connection with any of the matters described in clause (a) above, and
(c) reasonably cooperate in connection with any such matter, and the Corporate Taxpayer shall reimburse the ITR Entity for any reasonable third-party costs and expenses incurred pursuant to this Section. 

Section 6.4. Medifax Restructuring. 

(a) The Corporate Taxpayer shall promptly seek a legal opinion from a qualified firm mutually agreeable to the H&F ITR Entity and the BX
ITR Entity regarding the federal income tax consequences of the Medifax Restructuring, such restructuring to be in the form proposed by the BX ITR Entity and mutually agreeable to the H&F ITR Entity. If such opinion is at least “more likely
than not” that the Medifax Restructuring would have the intended federal income tax consequences (“Medifax Opinion”), the Corporate Taxpayer shall proceed to effectuate the Medifax Restructuring. 

(b) If a tax reserve relating to the intended income tax consequences of the Medifax Restructuring is established or increased subsequent to
the consummation thereof, any Tax Benefit Payment attributable to the Medifax Restructuring will be reduced by an amount equal to such Tax Benefit Payment attributable to the Medifax Restructuring (without regard to this provision) multiplied by the
ratio of (i) the tax reserve attributable to the Medifax Restructuring divided by (ii) the total amount of Tax Benefit Payments reasonably projected to be made attributable to the Medifax Restructuring resulting from the reallocation among
assets of previous adjustments made under Section 743(b) of the Code (the “743(b) Reallocation”). To the extent that the tax reserve attributable to the Medifax Restructuring is decreased, the Tax Benefit Payments attributable to the
Medifax Restructuring will be increased as of the time Tax Benefit Payments are next made by the amount of additional Tax Benefit Payments that would have been made previously had such decreased amount of the reserve never been recorded as a
reserve, together with interest at a rate of LIBOR plus 300 basis points, calculated from the time such additional Tax Benefit Payments would have been paid in the absence of such decreased reserve to the time that such Tax Benefit Payments are
actually paid. In the event that a tax reserve is recorded with respect to the Medifax Restructuring, the deductions attributable to the 743(b) Reallocation shall be deemed for purposes of this Agreement to be, among those deductions that produce
Tax Benefit Payments under this Agreement, to be the last such deductions used to offset taxable income. The cumulative, net amount of Tax Benefit Payments reduced pursuant to this provision shall not exceed the amount of tax reserves attributable
to the Medifax Restructuring. 
 (c) In the event that the Internal Revenue Service issues an Information Document Request (“IDR”)
relating to, or a 30-day letter, 90-day letter or other form of written communication identifying as an issue, the 743(b) Reallocation (any such written communication, a “Written IRS Notice”), the
obligation of the Corporate Taxpayer to make Tax Benefit Payments with respect to the 743(b) Reallocation shall be suspended indefinitely as of Parent or Corporate Taxpayer’s receipt of such Written IRS Notice. To the extent that the request or
issue relating to such 743(b) Reallocation is resolved in favor of Parent and the Corporate Taxpayer, Tax Benefit Payments attributable to the 743(b) Reallocation will be resumed and will be increased as of the time that Tax Benefit Payments are
next made by the amount of additional Tax Benefit Payments that would have been made previously had the Tax 

  
 -16- 

 
Benefit Payments attributable to the 743(b) Reallocation never been suspended, together with interest at a rate of LIBOR plus 300 basis, calculated from the time any such additional Tax Benefit
Payment would have been paid in the absence of such suspension to the time that such Tax Benefit Payment is actually paid. 
 (d) Payments
under Article III of the Tax Receivable Agreements shall be reduced, pro rata, by 85% of any tax cost (such as state and local taxes) resulting from the Medifax Restructuring, provided, that such reduction shall in no event exceed the amounts
payable under the Tax Receivable Agreements solely as a result of the Medifax Restructuring. 
 (e) In the event that the Medifax
Restructuring occurs, Parent and the Corporate Taxpayer will not liquidate Medifax-EDI Holding Company for a period of at least 24 months after the Medifax Restructuring is consummated.

Section 7.6. Successors; Assignment; Amendments; Waivers.

provided in such joinder.

(c) All of the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the

otherwise) to all or substantially all of the business or assets of the Corporate Taxpayer, by written agreement, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Corporate Taxpayer would be
required to perform if no such succession had taken place. For the avoidance of doubt, Parent shall expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Corporate Taxpayer would be required to
perform. 
 Section 7.7. Titles and Subtitles. The titles of the sections and subsections of this Agreement are for convenience
of reference only and are not to be considered in construing this Agreement. 
 Section 7.8. Resolution of Disputes. 

(a) Any and all disputes which cannot be settled amicably, including any ancillary claims of any party, arising out of, relating to or in
connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration provision) (each a
“Dispute”) shall be finally settled by arbitration conducted by a single arbitrator in New York in accordance with the then-existing Rules of Arbitration of the International Chamber of Commerce. If the parties to the Dispute fail
to agree on the selection of an arbitrator within ten (10) days of the receipt of the request for arbitration, the International Chamber of Commerce shall make the appointment. The arbitrator shall be a lawyer admitted to the practice of law in
the State of New York and shall conduct the proceedings in the English language. Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings. 

(b) Notwithstanding the provisions of paragraph (a), the Corporate Taxpayer may bring an action or special proceeding in any court of competent
jurisdiction for the purpose of compelling a party to arbitrate, seeking temporary or preliminary relief in aid of an arbitration hereunder, and/or enforcing an arbitration award and, for the purposes of this paragraph (b), the ITR Entity
(i) expressly consents to the application of paragraph (c) of this Section 7.8 to any such action or proceeding, (ii) agrees that proof shall not be required that monetary damages for breach of the provisions of this Agreement
would be difficult to calculate and that remedies at law would be inadequate, and (iii) irrevocably appoints the Corporate Taxpayer as agent of the ITR Entity for service of process in connection with any such action or proceeding and agrees

 -19- 

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

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

Section 7.9. Reconciliation. In the event that the Corporate Taxpayer and the ITR Entity are unable to resolve a disagreement with
respect to the matters governed by Sections 2.3, 4.2 and 6.2 within the relevant period designated in this Agreement (“Reconciliation Dispute”), the Reconciliation Dispute shall be submitted for determination to a nationally
recognized expert (the “Expert”) in the particular area of disagreement mutually acceptable to both parties. The Expert shall be a partner or principal in a nationally recognized accounting or law firm, and unless the Corporate
Taxpayer and the ITR Entity agree otherwise, the Expert shall not, and the firm that employs the Expert shall not, have any material relationship with the Corporate Taxpayer or the ITR Entity or other actual or potential conflict of interest. If the
parties are unable to agree on an Expert within fifteen (15) days of receipt by the respondent(s) of written notice of a Reconciliation Dispute, the Expert shall be appointed by the International Chamber of Commerce Centre for Expertise. The
Expert shall resolve any matter relating to the IPO Date Asset Disclosure Letter or an amendment thereto or the Early Termination Schedule or an amendment thereto within 30 calendar days and shall resolve any matter relating to a Tax Benefit
Schedule or an amendment thereto within 15 calendar days or as soon thereafter as is reasonably practicable, in each case after the matter has been submitted to the Expert for resolution. Notwithstanding the preceding sentence, if the matter is not
resolved before any payment that is the subject of a disagreement would be due (in the absence of such disagreement) or any Tax Return reflecting the subject of a disagreement is due, the undisputed amount shall be paid on the date prescribed by
this Agreement and such Tax Return may be filed as prepared by the Corporate Taxpayer, subject to adjustment or amendment upon resolution. The costs and expenses relating to the engagement of such Expert or amending any Tax Return shall be borne by
the Corporate Taxpayer except as provided in the next sentence. The Corporate Taxpayer and the ITR Entity shall bear their own costs and expenses of such proceeding, unless (i) the Expert adopts the ITR Entity’s position, in which case the
Corporate Taxpayer shall reimburse the ITR Entity for any reasonable out-of-pocket costs and expenses in such proceeding, or (ii) the Expert adopts the Corporate
Taxpayer’s position, in which case the ITR Entity shall reimburse the 

  
 -20- 

 
Corporate Taxpayer for any reasonable out-of-pocket costs and expenses in such proceeding. Any dispute as to
whether a dispute is a Reconciliation Dispute within the meaning of this Section 7.9 shall be decided by the Expert. The Expert shall finally determine any Reconciliation Dispute and the determinations of the Expert pursuant to this
Section 7.9 shall be binding on the Corporate Taxpayer and the ITR Entity and may be entered and enforced in any court having jurisdiction. 

Section 7.10. Withholding. The Corporate Taxpayer shall be entitled to deduct and withhold from any payment payable pursuant to
this Agreement such amounts as the Corporate Taxpayer is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign tax law. To the extent that amounts are so withheld and
paid over to the appropriate Taxing Authority by the Corporate Taxpayer, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the ITR Entity. 

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

(a) If the Corporate Taxpayer is or becomes a member of an affiliated or consolidated group of corporations that files a consolidated income
tax return pursuant to Sections 1501 et seq. of the Code or any corresponding provisions of state or local law, then: (i) the provisions of this Agreement shall be applied with respect to the group as a whole; and (ii) Tax Benefit
Payments, Early Termination Payments and other applicable items hereunder shall be computed with reference to the consolidated taxable income of the group as a whole. Parent shall file a consolidated income tax return that includes the Corporate
Taxpayer and each other member of the federal consolidated income group of which the Corporate Taxpayer was the common parent prior to Parent’s acquisition of the Corporate Taxpayer, and, after the Medifax Restructuring, Parent’s federal
consolidated income group is intended to include Medifax-EDI Holding Company and its subsidiaries. 

(b) If any entity that is obligated to make a Tax Benefit Payment or Early Termination Payment hereunder transfers one or more assets to a

 ARTICLE II 

DETERMINATION OF CERTAIN REALIZED TAX BENEFIT 

Section 2.1. Basis Adjustment. Within 90 calendar days after the filing of the United States federal income tax return of the
Corporate Taxpayer for each Taxable Year in which any Exchange has been effected, the Corporate Taxpayer shall deliver to the ITR Entity a schedule (the “Exchange Basis Schedule”) that shows, in reasonable detail necessary to
perform the calculations required by this Agreement, including with respect to each Exchanging party, for purposes of Taxes, (i) the Non-Stepped Up Tax Basis of the Reference Assets as of each applicable
Exchange Date, (ii) the Basis Adjustment with respect to the Reference Assets as a result of the Exchanges effected in such Taxable Year, calculated in the aggregate, (iii) the period (or periods) over which the Reference Assets are
amortizable and/or depreciable and (iv) the period (or periods) over which each Basis Adjustment is amortizable and/or depreciable. 

Section 2.2. Tax Benefit Schedule. 

(a) Tax Benefit Schedule. Within 90 calendar days after the filing of the United States federal income tax return of the Corporate
Taxpayer for any Taxable Year in which there is a Realized Tax Benefit or Realized Tax Detriment, the Corporate Taxpayer shall provide to the ITR Entity a schedule showing, in reasonable detail and, at the request of the ITR Entity, with respect to
each separate Exchange, the calculation of the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year (a “Tax Benefit Schedule”). The Tax Benefit Schedule will become final as provided in Section 2.3(a) and may be
amended as provided in Section 2.3(b) (subject to the procedures set forth in Section 2.3(b)). 
 (b) Applicable Principles.
Subject to Section 3.3(a), the Realized Tax Benefit or Realized Tax Detriment for each Taxable Year is intended to measure the decrease or increase in the actual liability for Taxes of the Corporate Taxpayer for such Taxable Year attributable
to the Basis Adjustments and Imputed Interest, determined using a “with and without” methodology. For the avoidance of doubt, the actual liability for Taxes will take into account the deduction of the portion of the Tax Benefit Payment
that must be accounted for as interest under the Code based upon the characterization of Tax Benefit Payments as additional consideration payable by the Corporate Taxpayer for the Units acquired in an Exchange. Carryovers or carrybacks of any Tax
item attributable to the Basis Adjustment and Imputed Interest shall be considered to be subject to the rules of the Code and the Treasury Regulations or the appropriate provisions of U.S. state and local income and franchise tax law, as applicable,
governing the use, limitation and expiration of carryovers or carrybacks of the relevant type. If a carryover or carryback of any Tax item includes a portion that is attributable to the Basis Adjustment or Imputed Interest and another portion that
is not, such portions shall be considered to be used in accordance with the “with and without” methodology. The parties agree that (i) all Tax Benefit Payments attributable to the Basis Adjustments (other than amounts accounted for as
interest under the Code) will (A) be treated as subsequent upward purchase price adjustments that give rise to further Basis Adjustments to Reference Assets for the Corporate Taxpayer and (B) have the effect of creating additional Basis
Adjustments to Reference Assets for the Corporate Taxpayer in the year of payment, and (ii) as a result, such additional Basis Adjustments will be incorporated into the current year calculation and into future year calculations, as appropriate.

 Section 2.3. Procedures, Amendments. 

(a) Procedure. Every time the Corporate Taxpayer delivers to the ITR Entity an applicable Schedule under this Agreement, including any
Amended Schedule delivered pursuant to Section 2.3(b), but excluding any Early Termination Schedule or amended Early Termination Schedule, the Corporate Taxpayer shall also (x) deliver to the ITR Entity schedules and work papers, as
determined by the Corporate Taxpayer or requested by the ITR Entity, providing reasonable detail regarding the preparation of the Schedule and (y) allow the ITR Entity reasonable access at no cost to the appropriate representatives at the
Corporate Taxpayer, as determined by the Corporate Taxpayer or requested by the ITR Entity, in connection with a review of such Schedule. Without limiting the application of the preceding sentence, each time the Corporate Taxpayer delivers to the
ITR Entity a Tax Benefit Schedule, in addition to the Tax Benefit Schedule duly completed, the Corporate Taxpayer shall deliver to the ITR Entity the Corporate Taxpayer Return, the reasonably detailed calculation by the Corporate Taxpayer of the
Hypothetical Tax Liability, the reasonably detailed calculation by the Corporate Taxpayer of the actual Tax liability, as well as any other work papers as determined by the Corporate Taxpayer or requested by the ITR Entity. An applicable Schedule or
amendment thereto shall become final and binding on all parties 30 calendar days from the first date on which the ITR Entity has received the applicable Schedule or amendment thereto unless the ITR Entity (i) within 30 calendar days after
receiving an applicable Schedule or amendment thereto, provides the Corporate Taxpayer with notice of a material objection to such Schedule (“Objection Notice”) made in good faith or (ii) provides a written waiver of such right
of any Objection Notice within the period described in clause (i) above, in which case such Schedule or amendment thereto becomes binding on the date the waiver is received by the Corporate Taxpayer. If the parties, for any reason, are unable
to successfully resolve the issues raised in the Objection Notice within 30 calendar days after receipt by the Corporate Taxpayer of an Objection Notice, the Corporate Taxpayer and the ITR Entity shall employ the reconciliation procedures as
described in Section 7.9 of this Agreement (the “Reconciliation Procedures”). 
 (b) Amended Schedule. The
applicable Schedule for any Taxable Year may be amended from time to time by the Corporate Taxpayer (i) in connection with a Determination affecting such Schedule, (ii) to correct inaccuracies in the Schedule identified as a result of the
receipt of additional factual information relating to a Taxable Year after the date the Schedule was provided to the ITR Entity, (iii) to comply with the Expert’s determination under the Reconciliation Procedures, (iv) to reflect a
change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to a carryback or carryforward of a loss or other tax item to such Taxable Year, (v) to reflect a change in the Realized Tax Benefit or Realized Tax
Detriment for such Taxable Year attributable to an amended Tax Return filed for such Taxable Year, or (vi) to adjust the Exchange Basis Schedule to take into account payments made pursuant to this Agreement (any such Schedule, an
“Amended Schedule”).

 ARTICLE III 

TAX BENEFIT PAYMENTS 

Section 3.1. Payments. 

(a) Payments. Within five (5) calendar days after a Tax Benefit Schedule delivered to the ITR Entity becomes final in accordance
with Section 2.3(a), the Corporate Taxpayer shall pay to the ITR Entity for such Taxable Year the Tax Benefit Payment determined pursuant to Section 3.1(b). Each such Tax Benefit Payment shall be made by wire transfer of immediately
available funds to the bank account previously designated by the ITR Entity to the Corporate Taxpayer or as otherwise agreed by the Corporate Taxpayer and the ITR Entity. For the avoidance of doubt, no Tax Benefit Payment shall be made in respect of
estimated tax payments, including, without limitation, federal estimated income tax payments. Notwithstanding anything herein to the contrary, unless the parties agree otherwise in writing upon request by the ITR Entity, in no event shall the
aggregate Tax Benefit Payments in respect of any Exchange (other than amounts accounted for as interest under the Code) exceed 50% of the purchase price for the Units exchanged. 

(b) A “Tax Benefit Payment” means an amount, not less than zero, equal to the sum of the Net Tax Benefit and the Interest
Amount. For the avoidance of doubt, for Tax purposes, the Interest Amount shall not be treated as interest but instead shall be treated as additional consideration for the acquisition of Units in Exchanges, unless otherwise required by law. Subject
to Section 3.3(a), the “Net Tax Benefit” for a Taxable Year shall be an amount equal to the excess, if any, of 85% of the Cumulative Net Realized Tax Benefit as of the end of such Taxable Year over the total amount of payments
previously made under this Section 3.1 (excluding payments attributable to Interest Amounts); provided, for the avoidance of doubt, that the ITR Entity shall not be required to return any portion of any previously made Tax Benefit
Payment. The “Interest Amount” shall equal the interest on the Net Tax Benefit calculated at the Agreed Rate from the due date (without extensions) for filing the Corporate Taxpayer Return with respect to Taxes for such Taxable Year
until the Payment Date. Notwithstanding the foregoing, for each Taxable Year ending on or after the date of a Change of Control, all Tax Benefit Payments, whether paid with respect to the Units that were Exchanged (i) prior to the date of such
Change of Control or (ii) on or after the date of such Change of Control, shall be calculated by utilizing Valuation Assumptions (1) and (3), substituting in each case the terms “the closing date of a Change of Control” for an
“Early Termination Date.” 
 Section 3.2. No Duplicative Payments. It is intended that the provisions of this
Agreement will not result in duplicative payment of any amount (including interest) required under this Agreement. It is also intended that the provisions of this Agreement provide that Tax Benefit Payments are paid to the ITR Entity pursuant to
this Agreement. The provisions of this Agreement shall be construed in the appropriate manner to ensure such intentions are realized. 

Section 3.3. Pro Rata Payments; Coordination of Benefits With Other Tax Receivable Agreements. 

(a) Notwithstanding anything in Section 3.1 to the contrary, to the extent that the aggregate tax benefit of the Corporate Taxpayer’s
deduction with respect to the NOLs, the Pre-IPO Basis Adjustments, the Basis Adjustments or Imputed Interest under the Tax Receivable Agreements (as such terms are defined in each Tax Receivable Agreement) is
limited in a particular Taxable Year because the Corporate Taxpayer does not have sufficient taxable 

  
 -12- 

 
income, the limitation on the tax benefit for the Corporate Taxpayer shall be allocated among the Tax Receivable Agreements (and among all parties eligible for payments thereunder) in proportion
to the respective amounts of Realized Tax Benefits that would have been determined under the Tax Receivable Agreements if the Corporate Taxpayer had sufficient taxable income so that there were no such limitation. 

(b) If for any reason the Corporate Taxpayer does not fully satisfy its payment obligations to make all Tax Benefit Payments due under the Tax
Receivable Agreements in respect of a particular Taxable Year, then the Corporate Taxpayer and the ITR Entity agree that (i) the Corporate Taxpayer shall pay the same proportion of each Tax Benefit Payment due under each of the Tax Receivable
Agreements in respect of such Taxable Year, without favoring one obligation over the other, and (ii) no Tax Benefit Payment shall be made in respect of any Taxable Year until all Tax Benefit Payments in respect of prior Taxable Years have been
made in full. 
 (c) To the extent that the Corporate Taxpayer makes payments to the ITR Entity in respect of a particular Taxable Year in an
amount greater than the payments that should have been made in accordance with Section 3.3(b), then the ITR Entity shall be obligated to make payments to the parties to the other Tax Receivable Agreements (other than the Corporate Taxpayer) in
the amounts necessary so that each party to the Tax Receivable Agreements shall have received the amount that it would have received if all payments by the Corporate Taxpayer had been in accordance with Section 3.3(b); provided, that the
ITR Entity’s obligation to pay over to the parties to the other Tax Receivable Agreements amounts received from the Corporate Taxpayer pursuant to this Section 3.3(c) shall terminate on the one year anniversary of the receipt by the ITR
Entity of such amounts. 
 (d) The parties hereto agree that the parties to the Investors Tax Receivable Agreement (Reorganizations) and the
parties to the Management Tax Receivable Agreement are expressly made third party beneficiaries of the provisions of this Section 3.3. 

ARTICLE IV 

TERMINATION 

Section 4.1. Early Termination and Breach of Agreement. 

(a) The Corporate Taxpayer may terminate this Agreement with respect to all amounts payable to the ITR Entity and with respect to all of the
Units held by HF Non-Corporate Members at any time by paying to the ITR Entity the Early Termination Payment; provided, that the Corporate Taxpayer may withdraw any notice to execute its termination
rights under this Section 4.1(a) prior to the time at which any Early Termination Payment has been paid. Upon payment of the Early Termination Payment by the Corporate Taxpayer, neither the ITR Entity nor the Corporate Taxpayer shall have any
further payment obligations under this Agreement, other than for any (a) Tax Benefit Payment agreed to by the Corporate Taxpayer and the ITR Entity as due and payable but unpaid as of the Early Termination Notice and (b) Tax Benefit
Payment due for the Taxable Year ending with or including the date of the Early Termination Notice (except to the extent that the amount described in this clause (b) is included in the Early Termination Payment). If an Exchange occurs after the
Corporate Taxpayer exercises its termination rights under this Section 4.1(a), the Corporate Taxpayer shall have no obligations under this Agreement with respect to such Exchange. 

  
 -13- 

 (b) In the event that the Corporate Taxpayer breaches any of its material obligations under
this Agreement, whether as a result of failure to make any payment when due, failure to honor any other material obligation required hereunder or by operation of law as a result of the rejection of this Agreement in a case commenced under the
Bankruptcy Code or otherwise, then all obligations hereunder shall be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the date of such breach and shall include, but not be limited to,
(1) the Early Termination Payment calculated as if an Early Termination Notice had been delivered on the date of a breach, (2) any Tax Benefit Payment agreed to by the Corporate Taxpayer and the ITR Entity as due and payable but unpaid as
of the date of a breach with respect to any Taxable Year prior to the Taxable Year ending with or including the date of a breach, and (3) any Tax Benefit Payment due for the Taxable Year ending with or including the date of a breach but reduced
by any amount with respect to the portion of such Taxable Year beginning after the date of such breach taken into account for purposes of determining the amount due under clause (1) of this sentence. Notwithstanding the foregoing, in the event
that the Corporate Taxpayer breaches this Agreement, the ITR Entity shall be entitled to elect to receive the amounts set forth in clauses (1), (2) and (3) above or to seek specific performance of the terms hereof. The parties agree that the
failure to make any payment due pursuant to this Agreement within three months of the date such payment is due shall be deemed to be a breach of a material obligation under this Agreement for all purposes of this Agreement, and that it will not be
considered to be a breach of a material obligation under this Agreement to make a payment due pursuant to this Agreement within three months of the date such payment is due. Notwithstanding anything in this Agreement to the contrary, it shall not be
a breach of this Agreement if the Corporate Taxpayer fails to make any Tax Benefit Payment when due to the extent that the Corporate Taxpayer has insufficient funds to make such payment; provided that the interest provisions of
Section 5.2 shall apply to such late payment (unless the Corporate Taxpayer does not have sufficient cash to make such payment as a result of limitations imposed by any credit agreement to which the Corporate Taxpayer or any of its Subsidiaries
is a party, in which case Section 5.2 shall apply, but the Default Rate shall be replaced by LIBOR plus 300 basis points). 

Section 4.2. Early Termination Notice. 

(a) If the Corporate Taxpayer chooses to exercise its right of early termination under Section 4.1 above other than in connection with a
Change of Control or Subsequent IPO, the Corporate Taxpayer shall deliver to the ITR Entity notice of such intention to exercise such right (“Early Termination Notice”) and a schedule (the “Early Termination
Schedule”) specifying the Corporate Taxpayer’s intention to exercise such right and showing in reasonable detail the calculation of the Early Termination Payment for the ITR Entity. The Early Termination Schedule shall become final and
binding on all parties 30 calendar days from the first date on which the ITR Entity has received such Schedule or amendment thereto unless the ITR Entity (i) within 30 calendar days after receiving the Early Termination Schedule, provides the
Corporate Taxpayer with notice of a material objection to such Schedule made in good faith (“Material Objection Notice”) or (ii) provides a written waiver of such right of a Material Objection Notice within the period described
in clause (i) above, in which case such Schedule becomes binding on the date the waiver is received by the Corporate Taxpayer (the “Early Termination Effective Date”). If the parties, for any reason, are unable to successfully
resolve the issues raised in such notice within 30 calendar days after receipt by the Corporate Taxpayer of the Material Objection Notice, the Corporate Taxpayer and the ITR Entity shall employ the Reconciliation Procedures. 

  
 -14- 

 (b) If the Corporate Taxpayer chooses to exercise its right of early termination under
Section 4.1 above in connection with a Change of Control or Subsequent IPO, any reference to 30 calendar days in Section 4.2(a) above shall instead be deemed to be 10 calendar days. 

Section 4.3. Payment upon Early Termination. 

(a) Within three calendar days after the Early Termination Effective Date, the Corporate Taxpayer shall pay to the ITR Entity an amount equal
to the Early Termination Payment. Such payment shall be made by wire transfer of immediately available funds to a bank account or accounts designated by the ITR Entity or as otherwise agreed by the Corporate Taxpayer and the ITR Entity. 

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

ARTICLE V 

SUBORDINATION AND LATE PAYMENTS 

Section 5.1. Subordination. Notwithstanding any other provision of this Agreement to the contrary, any payment required to be made
by the Corporate Taxpayer under this Agreement shall rank subordinate and junior in right of payment to any principal, interest or other amounts due and payable in respect of any obligations in respect of indebtedness for borrowed money of the
Corporate Taxpayer and its Subsidiaries (“Senior Obligations”) and shall rank pari passu with all current or future unsecured obligations of the Corporate Taxpayer that are not Senior Obligations. 

Section 5.2. Late Payments by the Corporate Taxpayer. The amount of all or any portion of any Tax Benefit Payment or Early
Termination Payment not made to the ITR Entity when due under the terms of this Agreement shall be payable together with any interest thereon, computed at the Default Rate and commencing from the date on which such Tax Benefit Payment or Early
Termination Payment was due and payable. 

  
 -15- 

 ARTICLE VI 

NO DISPUTES; CONSISTENCY; COOPERATION 

Section 6.1. Participation in the Corporate Taxpayer’s and EBS’s Tax Matters. Except as otherwise provided herein, the
Corporate Taxpayer shall have full responsibility for, and sole discretion over, all Tax matters concerning the Corporate Taxpayer and EBS, including without limitation the preparation, filing or amending of any Tax Return and defending, contesting
or settling any issue pertaining to Taxes. Notwithstanding the foregoing, the Corporate Taxpayer shall notify the ITR Entity of, and keep the ITR Entity reasonably informed with respect to, the portion of any audit of the Corporate Taxpayer and EBS
by a Taxing Authority the outcome of which is reasonably expected to affect the rights and obligations of the ITR Entity under this Agreement, and shall provide to the ITR Entity reasonable opportunity to provide information and other input to the
Corporate Taxpayer, EBS and their respective advisors concerning the conduct of any such portion of such audit; provided, however, that the Corporate Taxpayer and EBS shall not be required to take any action that is inconsistent with any provision
of the LLC Agreement. 
 Section 6.2. Consistency. The Corporate Taxpayer and the ITR Entity agree to report and cause to be
reported for all purposes, including federal, state and local Tax purposes and financial reporting purposes, all Tax-related items (including, without limitation, the Basis Adjustments and each Tax Benefit
Payment) in a manner consistent with that specified by the Corporate Taxpayer in any Schedule required to be provided by or on behalf of the Corporate Taxpayer under this Agreement unless otherwise required by law. 

Section 6.3. Cooperation. The ITR Entity shall (a) furnish to the Corporate Taxpayer in a timely manner such information,
documents and other materials as the Corporate Taxpayer may reasonably request for purposes of making any determination or computation necessary or appropriate under this Agreement, preparing any Tax Return or contesting or defending any audit,
examination or controversy with any Taxing Authority, (b) make itself available to the Corporate Taxpayer and its representatives to provide explanations of documents and materials and such other information as the Corporate Taxpayer or its
representatives may reasonably request in connection with any of the matters described in clause (a) above, and (c) reasonably cooperate in connection with any such matter, and the Corporate Taxpayer shall reimburse the ITR Entity for any
reasonable third-party costs and expenses incurred pursuant to this Section. 
 Section 6.4.
Medifax Restructuring. 
 (a) The Corporate Taxpayer shall promptly seek a legal opinion from a qualified firm mutually agreeable to
the H&F ITR Entity and the BX ITR Entity regarding the federal income tax consequences of the Medifax Restructuring, such restructuring to be in the form proposed by the BX ITR Entity and mutually agreeable to the H&F ITR Entity. If such
opinion is at least “more likely than not” that the Medifax Restructuring would have the intended federal income tax consequences (“Medifax Opinion”), the Corporate Taxpayer shall proceed to effectuate the Medifax Restructuring.

 (b) If a tax reserve relating to the intended income tax consequences of the Medifax Restructuring is established or increased subsequent
to the consummation thereof, any Tax Benefit Payment attributable to the Medifax Restructuring will be reduced by an amount equal to such Tax Benefit Payment attributable to the Medifax Restructuring (without regard to this provision) multiplied by
the ratio of (i) the tax reserve attributable to the Medifax Restructuring divided by (ii) the total amount of Tax Benefit Payments reasonably projected to be made attributable to the Medifax Restructuring resulting from the reallocation
among assets of previous adjustments made under Section 743(b) of the Code (the “743(b) Reallocation”). To 

  
 -16- 

 
the extent that the tax reserve attributable to the Medifax Restructuring is decreased, the Tax Benefit Payments attributable to the Medifax Restructuring will be increased as of the time Tax
Benefit Payments are next made by the amount of additional Tax Benefit Payments that would have been made previously had such decreased amount of the reserve never been recorded as a reserve, together with interest at a rate of LIBOR plus 300 basis
points, calculated from the time such additional Tax Benefit Payments would have been paid in the absence of such decreased reserve to the time that such Tax Benefit Payments are actually paid. In the event that a tax reserve is recorded with
respect to the Medifax Restructuring, the deductions attributable to the 743(b) Reallocation shall be deemed for purposes of this Agreement to be, among those deductions that produce Tax Benefit Payments under this Agreement, to be the last such
deductions used to offset taxable income. The cumulative, net amount of Tax Benefit Payments reduced pursuant to this provision shall not exceed the amount of tax reserves attributable to the Medifax Restructuring. 

(c) In the event that the Internal Revenue Service issues an Information Document Request (“IDR”) relating to, or a 30-day letter, 90-day letter or other form of written communication identifying as an issue, the 743(b) Reallocation (any such written communication, a “Written IRS Notice”), the obligation of the Corporate Taxpayer to
make Tax Benefit Payments with respect to the 743(b) Reallocation shall be suspended indefinitely as of Parent or Corporate Taxpayer’s receipt of such Written IRS Notice. To the extent that the request or issue relating to such 743(b)
Reallocation is resolved in favor of Parent and the Corporate Taxpayer, Tax Benefit Payments attributable to the 743(b) Reallocation will be resumed and will be increased as of the time that Tax Benefit Payments are next made by the amount of
additional Tax Benefit Payments that would have been made previously had the Tax Benefit Payments attributable to the 743(b) Reallocation never been suspended, together with interest at a rate of LIBOR plus 300 basis, calculated from the time any
such additional Tax Benefit Payment would have been paid in the absence of such suspension to the time that such Tax Benefit Payment is actually paid. 

(d) Payments under Article III of the Tax Receivable Agreements shall be reduced, pro rata, by 85% of any tax cost (such as state and local
taxes) resulting from the Medifax Restructuring, provided, that such reduction shall in no event exceed the amounts payable under the Tax Receivable Agreements solely as a result of the Medifax Restructuring. 

(e) In the event that the Medifax Restructuring occurs, Parent and the Corporate Taxpayer will not liquidate
Medifax-EDI Holding Company for a period of at least 24 months after the Medifax Restructuring is consummated.

arising out of, relating to or in connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of
this arbitration provision) (each a “Dispute”) shall be finally settled by arbitration conducted by a single arbitrator in New York in accordance with the then-existing Rules of Arbitration of
the International Chamber of Commerce. If the parties to the Dispute fail to agree on the selection of an arbitrator within ten (10) days of the receipt of the request for arbitration, the International Chamber of Commerce shall make the
appointment. The arbitrator shall be a lawyer admitted to the practice of law in the State of New York and shall conduct the proceedings in the English language. Performance under this Agreement shall continue if reasonably possible during any
arbitration proceedings. 
 (b) Notwithstanding the provisions of paragraph (a), the Corporate Taxpayer may bring an action or special
proceeding in any court of competent jurisdiction for the purpose of compelling a party to arbitrate, seeking temporary or preliminary relief in aid of an arbitration hereunder, and/or enforcing an arbitration award and, for the purposes of this
paragraph (b), the ITR Entity (i) expressly consents to the application of paragraph (c) of this Section 7.8 to any such action or proceeding, (ii) agrees that proof shall not be required that monetary damages for breach of the
provisions of this Agreement would be difficult to calculate and that remedies at law would be inadequate, and (iii) irrevocably appoints the Corporate Taxpayer as agent of the ITR Entity for service of process in connection with any such
action or proceeding and agrees that service of process upon such agent, who shall promptly advise the ITR Entity of any such service of process, shall be deemed in every respect effective service of process upon the ITR Entity in any such action or
proceeding. 
 (c) (i) EACH PARTY HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF COURTS LOCATED IN NEW YORK, NEW YORK FOR THE PURPOSE OF
ANY JUDICIAL PROCEEDING BROUGHT IN ACCORDANCE WITH THE PROVISIONS OF THIS SECTION 7.8, OR ANY JUDICIAL PROCEEDING ANCILLARY TO AN ARBITRATION OR CONTEMPLATED ARBITRATION ARISING OUT OF OR RELATING TO OR CONCERNING THIS AGREEMENT. Such ancillary
judicial proceedings include any suit, action or proceeding to compel arbitration, to obtain temporary or preliminary judicial relief in aid of arbitration, or to confirm an arbitration award. The parties acknowledge that the for a designated by
this paragraph (c) have a reasonable relation to this Agreement, and to the parties’ relationship with one another; and 
 (ii) The
parties hereby waive, to the fullest extent permitted by applicable law, any objection which they now or hereafter may have to personal jurisdiction or to the laying of venue of any such ancillary suit, action or proceeding brought in any court
referred to in the preceding paragraph of this Section 7.8 and such parties agree not to plead or claim the same.

 Section 7.9. Reconciliation. In the event that the Corporate Taxpayer and the
ITR Entity are unable to resolve a disagreement with respect to the matters governed by Sections 2.3, 4.2 and 6.2 within the relevant period designated in this Agreement (“Reconciliation Dispute”), the Reconciliation Dispute shall
be submitted for determination to a nationally recognized expert (the “Expert”) in the particular area of disagreement mutually acceptable to both parties. The Expert shall be a partner or principal in a nationally recognized
accounting or law firm, and unless the Corporate Taxpayer and the ITR Entity agree otherwise, the Expert shall not, and the firm that employs the Expert shall not, have any material relationship with the Corporate Taxpayer or the ITR Entity or other
actual or potential conflict of interest. If the parties are unable to agree on an Expert within fifteen (15) days of receipt by the respondent(s) of written notice of a Reconciliation Dispute, the Expert shall be appointed by the International
Chamber of Commerce Centre for Expertise. The Expert shall resolve any matter relating to the Exchange Basis Schedule or an amendment thereto or the Early Termination Schedule or an amendment thereto within 30 calendar days and shall resolve any
matter relating to a Tax Benefit Schedule or an amendment thereto within 15 calendar days or as soon thereafter as is reasonably practicable, in each case after the matter has been submitted to the Expert for resolution. Notwithstanding the
preceding sentence, if the matter is not resolved before any payment that is the subject of a disagreement would be due (in the absence of such disagreement) or any Tax Return reflecting the subject of a disagreement is due, the undisputed amount
shall be paid on the date prescribed by this Agreement and such Tax Return may be filed as prepared by the Corporate Taxpayer, subject to adjustment or amendment upon resolution. The costs and expenses relating to the engagement of such Expert or
amending any Tax Return shall be borne by the Corporate Taxpayer except as provided in the next sentence. The Corporate Taxpayer and the ITR Entity shall bear their own costs and expenses of such proceeding, unless (i) the Expert adopts the ITR
Entity’s position, in which case the Corporate Taxpayer shall reimburse the ITR Entity for any reasonable out-of-pocket costs and expenses in such proceeding, or
(ii) the Expert adopts the Corporate Taxpayer’s position, in which case the ITR Entity shall reimburse the Corporate Taxpayer for any reasonable out-of-pocket
costs and expenses in such proceeding. Any dispute as to whether a dispute is a Reconciliation Dispute within the meaning of this Section 7.9 shall be decided by the Expert. The Expert shall finally determine any Reconciliation Dispute and the
determinations of the Expert pursuant to this Section 7.9 shall be binding on the Corporate Taxpayer and the ITR Entity and may be entered and enforced in any court having jurisdiction. 

Section 7.10. Withholding. The Corporate Taxpayer shall be entitled to deduct and withhold from any payment payable pursuant to
this Agreement such amounts as the Corporate Taxpayer is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign tax law. To the extent that amounts are so withheld and
paid over to the appropriate Taxing Authority by the Corporate Taxpayer, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the ITR Entity.

 Section 7.11. Admission of the Corporate Taxpayer into a Consolidated Group;
Transfers of Corporate Assets. 
 (a) If the Corporate Taxpayer is or becomes a member of an affiliated or consolidated group of
corporations that files a consolidated income tax return pursuant to Sections 1501 et seq. of the Code or any corresponding provisions of state or local law, then: (i) the provisions of this Agreement shall be applied with respect to the group
as a whole; and (ii) Tax Benefit Payments, Early Termination Payments and other applicable items hereunder shall be computed with reference to the consolidated taxable income of the group as a whole. Parent shall file a consolidated income tax
return that includes the Corporate Taxpayer and each other member of the federal consolidated income group of which the Corporate Taxpayer was the common parent prior to Parent’s acquisition of the Corporate Taxpayer, and, after the Medifax
Restructuring, Parent’s federal consolidated income group is intended to include Medifax-EDI Holding Company and its subsidiaries. 

(b) If any entity that is obligated to make a Tax Benefit Payment or Early Termination Payment hereunder transfers one or more assets to a
corporation (or a Person classified as a corporation for U.S. income tax purposes) with which such entity does not file a consolidated tax return pursuant to Section 1501 of the Code, such entity, for purposes of calculating the amount of any
Tax Benefit Payment or Early Termination Payment (e.g., calculating the gross income of the entity and determining the Realized Tax Benefit of such entity) due hereunder, shall be treated as having disposed of such asset in a fully taxable
transaction on the date of such contribution. The consideration deemed to be received by such entity shall be equal to the fair market value of the contributed asset. For purposes of this Section 7.11, a transfer of a partnership interest shall
be treated as a transfer of the transferring partner’s share of each of the assets and liabilities of that partnership. 
 (c) Until
twelve months following the consummation of the Medifax Restructuring, Parent shall not cause (i) Holdco I or Holdco II to merge, liquidate or change its current election to be treated as a corporation for federal income tax purposes or
(ii) either of Holdco I or Holdco II to distribute their respective interests in EBS, provided, that this Section 7.11(c) shall not apply if the Corporate Taxpayer is unable to obtain the legal opinion referred to in Section 6.4(a)
within a reasonable period of time not to be less than nine months from the Closing Date. 
 Section 7.12. Confidentiality. The
ITR Entity and each of its assignees acknowledge and agree that the information of the Corporate Taxpayer is confidential and, except in the course of performing any duties as necessary for the Corporate Taxpayer and its Affiliates, as required by
law or legal process or to enforce the terms of this Agreement, such person shall keep and retain in the strictest confidence and not disclose to any Person any confidential matters, acquired pursuant to this Agreement, of the Corporate Taxpayer and
its Affiliates and successors, concerning EBS and its Affiliates and successors or the Members, learned by the ITR Entity heretofore or hereafter. This Section 7.12 shall not apply to (i) any information that has been made publicly
available by the Corporate Taxpayer or any of its Affiliates, becomes public knowledge (except as a result of an act of the ITR Entity in violation of this Agreement) or is generally known to the business community and (ii) the disclosure of
information to the extent necessary for the ITR Entity to prepare and file its Tax Returns, to respond to any inquiries regarding the same from any taxing authority or to prosecute or defend any action, proceeding or audit by any taxing authority
with respect to such returns. Notwithstanding anything to the contrary herein, the ITR Entity and each of its assignees (and each employee, representative or other agent of the ITR Entity or its assignees, as applicable) may disclose to any and all
Persons, without limitation of any kind, the tax treatment and tax structure of the Corporate Taxpayer, EBS, the ITR Entity, the Members and their Affiliates, and any of their transactions, and all materials of any kind (including opinions or other
tax analyses) that are provided to the ITR Entity relating to such tax treatment and tax structure. 

  
 -22- 

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

Section 7.13. Representations. 

(a) The HF ITR Entity hereby represents that the HF Members have contributed to the HF ITR Entity, and the HF ITR Entity has received, all of
the HF Members’ rights to receive payments in respect of the Corporate Taxpayer’s cash Tax savings attributable to various tax benefits generated by the Exchanges (including their rights under this Agreement). 

(b) The HF ITR Entity and the ITR Entity hereby represent that the HF ITR Entity has contributed to the ITR Entity, and the ITR Entity has
received, all of the HF ITR Entity’s rights to receive payments in respect of the Corporate Taxpayer’s cash Tax savings attributable to various tax benefits generated by the Exchanges (including their rights under this Agreement).
