Emdeon 
 Management Bonus
Program 
 PURPOSE 
 The purpose of the
Emdeon Management Bonus Program (the “Program”) is to provide an incentive to management level employees of Emdeon and its participating subsidiaries (the “Company”) who contribute to the success of the enterprise. The Program
offers eligible employees an opportunity to earn compensation in addition to their salaries, based upon the performance of the Company (including its Divisions/Business Units) and the accomplishment of their Individual Goals. 

PROGRAM ADMINISTRATION 
 The Compensation Committee
of the Board of Directors (the “Committee”), in consultation with the Chief Executive Officer of the Company (the “CEO”), shall administer the Program. The CEO will oversee and interpret (including the amount payable to any
individual participant) any and all aspects of the Program. The CEO (other than with respect to himself) shall make final recommendations to the Committee regarding both the amount and the timing of any bonus payments pursuant to the Program. The
Committee shall review and approve the CEO’s recommendations. 
 PROGRAM YEAR 

The Program will be effective from January 1 of each fiscal year of the Company through December 31 of such fiscal year (the “Program
Year”). 
 PARTICIPANT ELIGIBILITY 

Eligible participants generally include regular full-time employees classified as Director level and above. 

An employee must be employed or meet the eligibility criteria on or before September 30 of the Program Year to be eligible to participate in the
Program for that year. If a person otherwise eligible for participation in the Program becomes an employee of the Company during the fiscal year, the employee will be eligible to receive a prorated portion of the annual bonus based upon the
employee’s first date of employment. Generally, ineligible participants would include: 
  

	 	•	 	Temporary employees, independent contractors and consultants 

  

	 	•	 	Anyone eligible to participate in a commission plan or other cash incentive plan 

  

	 	•	 	Employees who do not have a signed Trade Secret and Proprietary Information Agreement on file with the Company 

  

	 	•	 	Anyone not actively employed on the date the bonuses are distributed 

  

	 	•	 	Any other employee that does not meet the eligibility criteria above 

 An employee must be an active employee of the Company on the date the bonuses are distributed to employees to
be eligible to receive any payment under the Program. 
 BONUS POTENTIAL 

The target bonus potential is calculated as a percentage of the employee’s annual salary as of December 31 of the Program Year to which the bonus
relates. The guidelines for determining target bonus potential are based on the employee’s level and role. These guidelines, however, may be adjusted to reflect the significance, scope and level of accountability for a given position.
Adjustments (increases or reductions) to the target bonus potential levels may be made at the discretion of the CEO. Additionally, certain employee bonus potential amounts are set forth in written employment agreements. As such, these written
agreements shall be controlling. 
 PROGRAM COMPONENTS 

The funding and payment of bonuses is based upon three separate Program components. The three components are the Company Performance Targets, Division/Business
Unit Performance Targets and Individual Goals. 
 For all eligible employees, a portion of the bonus potential will be based on the Company’s
Performance Targets and Individual Goals. In addition, for those employees whose job responsibilities are primarily related to a particular Division/Business Unit, a portion of the bonus potential will also be based on the achievement of
Division/Business Unit Performance Targets. 
 The funding of bonuses under the Program is dependent on the achievement of Company Performance Targets and
Division/Business Unit Performance Targets. The Company must declare the payment of bonuses before any types of payment under this Program can or will be paid. If, and when, bonuses are declared, financial calculations will be made to determine a
funding level for each employee. Individual bonus payouts are then determined by performance against Individual Goals. 
 The Program contains several
objectives. Each objective has a minimum, target and a maximum level of performance. For each objective, the bonus payment will range from zero to a maximum percentage based on the level of performance for that objective. 

 

	•	 	Company Performance Targets 

 Payments are contingent upon the Company achieving the Company
Performance Targets as shall be set by the Committee within the first ninety days of a Program Year. 

  
 2 

	•	 	Division/Business Unit Performance Targets 

 For those eligible employees whose job
responsibilities are primarily related to a particular Division/Business Unit, payments for a portion of the employee’s bonus amount are contingent upon the Division/Business Unit achieving the Division/Business Unit Performance Targets as
shall be set by the Committee with respect to each Program Year. 
  

	•	 	Individual Goals 

 The achievement of Individual Goals (based on Company objectives) is a very
important component of the Program. Once the Company and/or the Division/Business Unit have achieved their performance goals, individual bonus potential can be greatly impacted by the level of achievement of Individual Goals as determined by each
eligible employee’s manager. 
 Managers will review each of their bonus-eligible employees and will make a recommendation of 100% to 0% of the bonus
amount based on the achievement of Individual Goals. Managers cannot distribute or recommend more the 100% of an individual employee’s target amount. However, the bonus recommendation can be reduced or increased at the discretion of the CEO.

 TRANSFER/PROMOTION/DEMOTION 
 If an employee
is transferred to a new role during the Program Year, the employee will be eligible to participate in the incentive plan that applies to the new role. However, if an employee who was not eligible for participation in the Program is promoted to a
position eligible for participation in the Program after September 30th of the Program Year, the employee will not be eligible to participate in the Program until January 1st of the following year. 

If the employee becomes ineligible for this Program due to a transfer, demotion or promotion, the employee will be eligible to receive a prorated award based
on the period of participation in the Program; provided, that the employee must continue to meet the “Conditions For Receiving Payment” set forth below. Such prorated award will be paid at the same time as awards under the Program. 

PAYOUT AND TAXATION 
 The Company anticipates any
bonus amounts earned under the Program for each Program Year will be paid around March of the year following that Program Year after completion of audited financial statements for the Program Year and final executive and Committee approval. Specific
provisions regarding distribution are outlined below under the “Conditions for Receiving Payment” section of the Program. 
 Payroll taxes will be
withheld from the bonus award as required by law. Bonus awards that employees receive will be reported as income in the year in which they are paid. Therefore, the bonus payment with respect to a Program Year, which is expected to be paid in March
of the following year, will be reported as part of an employee’s total W-2 income for the tax year following the Program Year. 

  
 3 

 CONDITIONS FOR RECEIVING PAYMENT 

No bonus award under this Program will be paid to any employee if employment is terminated, whether voluntary or involuntary, prior to the actual payment
distribution date. However, the Company retains the authority to make exceptions to the foregoing policy in unusual or meritorious cases including, but not limited to, the death of an employee during the fiscal year, termination of employment due to
total or partial disability, call to active military service or retirement with the written consent of the Company. 
 LIMITATIONS AND/OR ADJUSTMENTS

 Bonus compensation under the Program is not an integral part of an employee’s compensation package. An employee’s base salary
compensates the employee for the expected results of any given job. Payment of the bonus compensation is at the discretion of the Company. The Company reserves the right to review, amend, suspend and/or terminate the Program, the incentive
calculation formulas and all other aspects of the Program at any time. Program changes will be based on a determination of the Company’s business needs and do not require prior notification or explanation to eligible employees. 

An employee’s participation in the Program shall not be construed as an employment contract or as a promise of continuing employment between the Company
and the employee. Employment with the Company is terminable at will.

 (b) Each such grant or sale may be made without
additional consideration or in consideration of a payment by such Participant that is less than the Market Value per Unit at the Date of Grant.

achievement of the applicable Management Objectives and the end of any applicable time-based vesting period. 
 (f) Each grant or sale of
Phantom Units will specify the time and manner of payment of the Phantom Units that have been earned. Each grant or sale will specify that the amount payable with respect thereto will be paid by the Company in Units, cash, or a combination thereof.

 (g) Each grant or sale of Phantom Units will be evidenced by an Evidence of Award and will contain such terms and provisions, consistent
with this Plan, as the Committee may approve.

result in payment or early payment of the Award, and each grant may specify in respect of such specified Management Objectives a minimum acceptable level or levels of achievement and may set forth a formula for

  
 10 

 
determining the number of Performance Units, or amount payable with respect to Cash Incentive Awards, that will be earned if performance is at or above the minimum or threshold level or levels,
or is at or above the target level or levels, but falls short of maximum achievement of the specified Management Objectives. 

(d) Each grant will specify the time and manner of payment of Cash Incentive Awards or Performance Units that have been earned.
Any grant may specify that the amount payable with respect thereto may be paid by the Partnership in cash, in Units, Restricted Units or in any combination thereof. 

(e) Any grant of Cash Incentive Awards or Performance Units may specify that the amount payable or the number of Units or
Restricted Units with respect thereto may not exceed a maximum specified by the Committee at the Date of Grant. 
 (f) The
Committee may, at the Date of Grant of Performance Units, provide for the payment of DERs to the holder thereof either in cash or in additional Units, subject in all cases to deferral and payment on a contingent basis based on the Participant’s
earning of the Performance Units with respect to which such DERs are paid. 
 (g) Each grant of Cash Incentive Awards or
Performance Units will be evidenced by an Evidence of Award and will contain such other terms and provisions, consistent with this Plan, as the Committee may approve. 

9. Other Awards. 

(a) Subject to applicable law and the limit set forth in Section 3(c) of this Plan, the Committee may grant
to any Participant such Other Awards (including profits interests) that may be denominated or payable in, valued in whole or in part by reference to, or otherwise based on, or related to, Units or factors that may influence the value of such units,
including, without limitation, convertible or exchangeable debt securities, other rights convertible or exchangeable into Units, purchase rights for Units, awards with value and payment contingent upon performance of the Partnership or specified
Subsidiaries, Affiliates of the Partnership or other business units thereof or any other factors designated by the Committee, and awards valued by reference to the book value of the Units or the value of securities of, or the performance of
specified Subsidiaries or Affiliates of the Partnership or other business units of the Partnership. The Committee will determine the terms and conditions of such Other Awards. Units delivered pursuant to an Other Award in the nature of a purchase
right granted under this Section 9 will be purchased for such consideration, paid for at such time, by such methods, and in such forms, including, without limitation, Units, Other Awards, notes or other property, as the Committee
determines. 
 (b) Cash awards, as an element of or supplement to any Award granted under this Plan, may also be granted
pursuant to this Section 9. 
 (c) The Committee may grant Units as a bonus, or may grant Other Awards in lieu
of obligations of the Partnership or a Subsidiary to pay cash or deliver other property under this Plan or under other plans or compensatory arrangements, subject to such terms as will be determined by the Committee in a manner that complies with
Section 409A of the Code. 
 (d) Notwithstanding anything to the contrary contained in this Plan, any grant of an Other
Award under this Section 9 may provide for the earning or vesting of, or earlier elimination of restrictions applicable to, such Other Award, including (i) in the event of the retirement, death or disability of the
Participant, or (ii) in the event of a Change in Control.

 10. Administration of the Plan. 

(a) This Plan will be administered by the Committee. The Committee may from time to time delegate all or any part of its
authority under this Plan to a subcommittee thereof. To the extent of any such delegation, references in this Plan to the Committee will be deemed to be references to such subcommittee. 

(b) The interpretation and construction by the Committee of any provision of this Plan or of any agreement, notification or
document evidencing the grant of Awards under this Plan and any determination by the Committee pursuant to any provision of this Plan or of any such agreement, notification or document will be final and conclusive. No member of the Committee shall
be liable for any such action or determination made in good faith. In addition, the Committee is authorized to take any action it determines in its sole discretion to be appropriate subject only to the express limitations contained in this Plan, and
no authorization in any Plan Section or other provision of this Plan is intended or may be deemed to constitute a limitation on the authority of the Committee. 

(c) The Committee may delegate to one or more of its members or to one or more officers of the Partnership, or to one or more
agents or advisors, such administrative duties or powers as it may deem advisable, and the Committee, the subcommittee, or any person to whom duties or powers have been delegated as aforesaid, may employ one or more persons to render advice with
respect to any responsibility the Committee, the subcommittee or such person may have under the Plan. The Committee may, by resolution, authorize one or more key employees of the Partnership, Company or their Affiliates to do one or both of the
following on the same basis as the Committee: (i) designate employees to be recipients of Awards under this Plan; and (ii) determine the size of any such Awards; provided, however, that (A) the Committee will not
delegate such responsibilities to any such officer for Awards granted to an employee who is an officer, Director, or more than 10% beneficial owner of any class of the Partnership’s equity securities that is registered pursuant to
Section 12 of the Exchange Act, as determined by the Committee in accordance with Section 16 of the Exchange Act; (B) the resolution providing for such authorization sets forth the total number of Units such officer(s) may grant; and
(C) the officer(s) will report periodically to the Committee regarding the nature and scope of the Awards granted pursuant to the authority delegated. 

11. Adjustments. The Committee will make or provide for such adjustments in the numbers of Units covered by outstanding Option Rights,
Appreciation Rights, Phantom Units, DERs and Performance Units granted hereunder and, if applicable, in the number of Units covered by Other Awards granted pursuant to Section 9 hereof, in the Option Price and Base Price provided
in outstanding Option Rights and Appreciation Rights, in the kind of units covered thereby, and in Cash Incentive Awards as the Committee, in its sole discretion, 

  
 12 

 
exercised in good faith, may determine is equitably required to prevent dilution or enlargement of the rights of Participants or Optionees that otherwise would result from (a) any
recapitalization or other change in the capital structure of the Partnership, (b) any merger, consolidation, spin-off, split-off, spin-out, split-up, reorganization, partial or complete liquidation or other distribution of assets, issuance of
rights or warrants to purchase securities, or (c) any other transaction or event having an effect similar to any of the foregoing. Moreover, in the event of any such transaction or event or in the event of a Change in Control, the Committee, in
its discretion, may provide in substitution for any or all outstanding Awards under this Plan such alternative consideration (including cash), if any, as it, in good faith, may determine to be equitable in the circumstances and may require in
connection therewith the surrender of all Awards so replaced in a manner that complies with Section 409A of the Code. In addition, for each Option Right or Appreciation Right with an Option Price or Base Price greater than the consideration
offered in connection with any such transaction or event or Change in Control, the Committee may in its sole discretion elect to cancel such Option Right or Appreciation Right without any payment to the person holding such Option Right or
Appreciation Right. The Committee will also make or provide for such adjustments in the numbers of units specified in Section 3 of this Plan as the Committee in its sole discretion, exercised in good faith, may determine is
appropriate to reflect any transaction or event described in this Section 11. 
 12. Non U.S. Participants. In
order to facilitate the making of any grant or combination of grants under this Plan, the Committee may provide for such special terms for Awards to Participants who are foreign nationals or who are employed by the Partnership or any Subsidiary
outside of the United States of America or who provide services to the Partnership under an agreement with a foreign nation or agency, as the Committee may consider necessary or appropriate to accommodate differences in local law, tax policy or
custom. Moreover, the Committee may approve such supplements to or amendments, restatements or alternative versions of this Plan (including, without limitation, sub-plans) as it may consider necessary or appropriate for such purposes, without
thereby affecting the terms of this Plan as in effect for any other purpose, and the Secretary or other appropriate officer of the Partnership may certify any such document as having been approved and adopted in the same manner as this Plan. No such
special terms, supplements, amendments or restatements, however, will include any provisions that are inconsistent with the terms of this Plan as then in effect unless this Plan could have been amended to eliminate such inconsistency without further
approval by the partners of the Partnership. 
 13. Transferability. 

(a) Except as otherwise determined by the Committee, no Option Right, Appreciation Right, Restricted Unit, Phantom Unit,
Performance Unit, Cash Incentive Award, Other Award of this Plan or DER paid with respect to Awards made under this Plan will be transferable by the Participant except by will or the laws of descent and distribution, and in no event will any such
Award granted under the Plan be transferred for value. Except as otherwise determined by the Committee, Option Rights and Appreciation Rights will be exercisable during the Participant’s lifetime only by him or her or, in the event of the
Participant’s legal incapacity to do so, by his or her guardian or legal representative acting on behalf of the Participant in a fiduciary capacity under state law or court supervision. 

(b) The Committee may specify at the Date of Grant that part or all of the Units that are (i) to be issued or transferred
by the Partnership upon the exercise of Option Rights or Appreciation Rights, upon the termination of the Restriction Period applicable to Restricted Units or upon payment under any grant of Phantom Units or Performance Units or (ii) no longer
subject to the substantial risk of forfeiture and restrictions on transfer referred to in Section 6 of this Plan, will be subject to further restrictions on transfer. 

  
 13 

 14. Withholding Taxes. To the extent that the Partnership is required to withhold federal,
state, local or foreign taxes in connection with any payment made or benefit realized by a Participant or other person under this Plan, and the amounts available to the Partnership for such withholding are insufficient, it will be a condition to the
receipt of such payment or the realization of such benefit that the Participant or such other person make arrangements satisfactory to the Partnership for payment of the balance of such taxes required to be withheld, which arrangements (in the
discretion of the Committee) may include relinquishment of a portion of such benefit. If a Participant’s benefit is to be received in the form of Units, and such Participant fails to make arrangements for the payment of tax, then, unless
otherwise determined by the Committee, the Partnership will withhold Units having a value equal to the amount required to be withheld. Notwithstanding the foregoing, when a Participant is required to pay the Partnership an amount required to be
withheld under applicable income and employment tax laws, the Participant may elect, unless otherwise determined by the Committee, to satisfy the obligation, in whole or in part, by having withheld, from the Awards required to be delivered to the
Participant, Units having a value equal to the amount required to be withheld (except in the case of Restricted Units where an election under Section 83(b) of the Code has been made), or by delivering to the Partnership other Units held by such
Participant. The Units used for tax withholding will be valued at an amount equal to the market value of such Units on the date the benefit is to be included in Participant’s income. In no event will the market value of the Units to be withheld
and delivered pursuant to this Section to satisfy applicable withholding taxes in connection with the benefit exceed the minimum amount of taxes required to be withheld. Participants will also make such arrangements as the Partnership may require
for the payment of any withholding tax obligation that may arise in connection with the disposition of Units acquired upon the exercise of Option Rights. 

15. Compliance with Section 409A of the Code.  

(a) To the extent applicable, it is intended that this Plan and any grants made hereunder comply with the provisions of
Section 409A of the Code, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to the Participants. This Plan and any grants made hereunder will be administered in a manner consistent with this intent. Any
reference in this Plan to Section 409A of the Code will also include any regulations or any other formal guidance promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service. 

(b) Neither a Participant nor any of a Participant’s creditors or beneficiaries will have the right to subject any
deferred compensation (within the meaning of Section 409A of the Code) payable under this Plan and grants hereunder to any anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment. Except as permitted
under Section 409A of the Code, any deferred compensation (within the meaning of 

  
 14 

 
Section 409A of the Code) payable to a Participant or for a Participant’s benefit under this Plan and grants hereunder may not be reduced by, or offset against, any amount owing by a
Participant to the Partnership or any of its Subsidiaries. 
 (c) If, at the time of a Participant’s separation from
service (within the meaning of Section 409A of the Code), (i) the Participant will be a specified employee (within the meaning of Section 409A of the Code and using the identification methodology selected by the Partnership from time
to time) and (ii) the Partnership makes a good faith determination that an amount payable hereunder constitutes deferred compensation (within the meaning of Section 409A of the Code) the payment of which is required to be delayed pursuant
to the six-month delay rule set forth in Section 409A of the Code in order to avoid taxes or penalties under Section 409A of the Code, then the Partnership will not pay such amount on the otherwise scheduled payment date but will instead
pay it, without interest, on the tenth business day of the seventh month after such separation from service. 
 (d)
Notwithstanding any provision of this Plan and grants hereunder to the contrary, in light of the uncertainty with respect to the proper application of Section 409A of the Code, the Partnership reserves the right to make amendments to this Plan
and grants hereunder as the Partnership deems necessary or desirable to avoid the imposition of taxes or penalties under Section 409A of the Code. In any case, a Participant will be solely responsible and liable for the satisfaction of all
taxes and penalties that may be imposed on a Participant or for a Participant’s account in connection with this Plan and grants hereunder (including any taxes and penalties under Section 409A of the Code), and neither the Partnership,
Company nor any of their Affiliates will have any obligation to indemnify or otherwise hold a Participant harmless from any or all of such taxes or penalties. 

16. Amendments. 

(a) Except as required by applicable law or the rules of the principal securities exchange on which the Units are traded, the
Board may at any time and from time to time amend this Plan in whole or in part. 
 (b) If permitted by Section 409A of
the Code, but subject to the paragraph that follows, including in the case of termination of employment by reason of death, disability or retirement, or in the event of a Change in Control, to the extent a Participant holds an Option Right or
Appreciation Right not immediately exercisable in full, or any Restricted Units or Phantom Units as to which the substantial risk of forfeiture or the prohibition or restriction on transfer has not lapsed, or any Cash Incentive Awards or Performance
Units which have not been fully earned, or any Other Awards subject to any vesting schedule or transfer restriction, or who holds Units subject to any transfer restriction imposed pursuant to Section 13(b) of this Plan, the
Committee may, in its sole discretion, accelerate the time at which such Option Right, Appreciation Right or Other Award may be exercised or the time at which such substantial risk of forfeiture or prohibition or restriction on transfer with respect
to a Restricted Unit or a Phantom Unit will lapse or the time when such Restriction Period will end or the time at which such Cash Incentive Awards, Phantom Units or Performance Units will be deemed to have been fully earned or the time when such
transfer restriction will terminate or may waive any other limitation or requirement under any such Award. 

  
 15 

 Except as required by applicable law or the rules of the principal securities exchange on which
the Units are traded, the Committee may amend the terms of any Award theretofore granted under this Plan prospectively or retroactively. Subject to Section 11 above, no such amendment will impair the rights of any Participant
without his or her consent. The Board may, in its discretion, terminate this Plan at any time. Termination of this Plan will not affect the rights of Participants or their successors under any Awards outstanding hereunder and not exercised in full
on the date of termination. 
 17. Governing Law. This Plan and all grants and Awards and actions taken hereunder will be governed by
and construed in accordance with the internal substantive laws of the State of Delaware. 
 18. Miscellaneous Provisions. 

(a) The Partnership will not be required to issue any fractional Units pursuant to this Plan. The Committee may provide for the
elimination of fractions or for the settlement of fractions in cash. 
 (b) This Plan will not confer upon any Participant
any right with respect to continuance of employment or other service with the Partnership or any Subsidiary, nor will it interfere in any way with any right the Partnership or any Subsidiary would otherwise have to terminate such Participant’s
employment or other service at any time. 
 (c) No Award under this Plan may be exercised by the holder thereof if such
exercise, and the receipt of Units thereunder, would be, in the opinion of counsel selected by the Partnership, contrary to law or the regulations of any duly constituted authority having jurisdiction over this Plan. 

(d) Absence on leave approved by a duly constituted officer of the Partnership or any of its Subsidiaries will not be
considered interruption or termination of service of any employee for any purposes of this Plan or Awards granted hereunder. 

(e) No Participant will have any rights as a Unitholder with respect to any Units subject to Awards granted to him or her under
this Plan prior to the date as of which he or she is actually recorded as the holder of such Units upon the records of the Partnership. 

(f) The Committee may condition the grant of any Award or combination of Awards authorized under this Plan on the surrender or
deferral by the Participant of his or her right to receive a cash bonus or other compensation otherwise payable by the Partnership or a Subsidiary to the Participant. 

(g) Except with respect to Option Rights and Appreciation Rights, the Committee may permit Participants to elect to defer the
issuance of Units or the payment of cash under the Plan pursuant to such rules, procedures or programs as it may establish for purposes of this Plan and which are intended to comply with the requirements of Section 409A of the Code. The
Committee also may provide that deferred issuances and settlements include the payment or crediting of DERs or interest on the deferral amounts. 

(h) If any provision of this Plan is or becomes invalid or unenforceable in any jurisdiction, or would disqualify this Plan or
any Award under any law deemed applicable by the Committee, such provision will be construed or deemed amended or limited in scope to conform to applicable laws or, in the discretion of the Committee, it will be stricken and the remainder of this
Plan will remain in full force and effect. 

  
 16 

 19. Unit-Based Awards in Substitution for Option Rights or Awards Granted by Other Entity.
Notwithstanding anything in this Plan to the contrary: 
 (a) Awards may be granted under this Plan in substitution for or in
conversion of, or in connection with equity-based awards held by awardees of an entity engaging in a corporate acquisition or merger transaction with the Partnership or any Subsidiary. Any conversion, substitution or assumption will be effective as
of the close of the merger or acquisition, and, to the extent applicable, will be conducted in a manner that complies with Section 409A of the Code. The Awards so granted may reflect the original terms of the awards being assumed or substituted
or converted for and need not comply with other specific terms of this Plan, and may account for Units substituted for the securities covered by the original awards and the number of Securities subject to the original awards, as well as any exercise
or purchase prices applicable to the original awards, adjusted to account for differences in prices in connection with the transaction. 

(b) In the event that an entity acquired by the Partnership or any Subsidiary or with which the Partnership or any Subsidiary
merges has securities available under a pre-existing plan previously approved by shareholders/partners and not adopted in contemplation of such acquisition or merger, the securities available for grant pursuant to the terms of such plan (as
adjusted, to the extent appropriate, to reflect such acquisition or merger) may be used for awards made after such acquisition or merger under the Plan; provided, however, that Awards using such available securities may not be made
after the date awards or grants could have been made under the terms of the pre-existing plan absent the acquisition or merger, and may only be made to individuals who were not employees or Directors of the Partnership or any Subsidiary prior to
such acquisition or merger. 
 (c) Any Units that are issued or transferred by, or that are subject to any Awards that are
granted by, or become obligations of, the Partnership under Sections 19(a) or 19(b) above will not reduce the Units available for issuance or transfer under the Plan or otherwise count against the limits contained in
Section 3 of the Plan. In addition, no Units that are issued or transferred by, or that are subject to any Awards that are granted by, or become obligations of, the Partnership under Sections 19(a) or
19(b) above will be added to the aggregate Plan limit contained in Section 3 of the Plan.
