speculative investment which involves a high degree of risk of loss of Executive’s investment therein, there are substantial restrictions on the transferability of the Units and, on the Closing Date and for an indefinite period following the

Company or its Subsidiaries, the Company and its Affiliates have the right to repurchase the Units at a price which may, under certain circumstances, be less than the Fair Market Value thereof;

(B) if such termination occurs after January 28, 2010, the Fair Market Value thereof; and 

(iv) Competitive Activity. In the event Executive engages in a Competitive Activity not constituting a Restrictive

 4.3 Obligation to Sell Several. If there is more than one member of Executive’s Group, the failure of any one
member thereof to perform its obligations hereunder shall not excuse or affect the obligations of any other member thereof, and the closing of the purchases from such other members by the Company shall not excuse, or constitute a waiver of its
rights against, the defaulting member. 
 5. Certain Limitations on the Company’s Obligations to Purchase Units. 

5.1 Prohibition of Purchases. Notwithstanding anything to the contrary contained herein, the Company shall not be obligated to
purchase any Units at any time pursuant to Section 4, regardless of whether it has delivered a notice of its election to purchase any such Units, to the extent that the purchase of such Units or the payment to the Company or one of its
Subsidiaries of a cash dividend or distribution by a Subsidiary of the Company that is necessary to fund such purchase (together with any other purchases of Units pursuant to Section 4 or pursuant to similar provisions in agreements with other
employees of the Company and its Subsidiaries of which the Company has at such time been given or has given notice and together with cash dividends and distributions necessary to fund such other purchases) would result in a violation of any law,
statute, rule, regulation, policy, order, writ, injunction, decree or judgment promulgated or entered by any federal, state, local or foreign court or governmental authority applicable to the Company or any of its Subsidiaries or any of its or their
property. The Company shall, within fifteen days of learning of any such fact, so notify the members of Executive’s Group that it is not obligated to purchase Units hereunder. 

5.2 Payment for Units. If at any time the Company elects or is required to purchase any Units pursuant to Section 4, the
Company shall pay the purchase price for the Units it purchases (i) first, by the cancellation of any indebtedness, if any, owing from Executive to the Company or any of its Subsidiaries (which indebtedness shall be applied pro rata against the
proceeds receivable by each member of Executive’s Group receiving consideration in such repurchase) and (ii) then, by the Company’s delivery of a check or wire transfer of immediately available funds for the remainder of the purchase
price, if any, against delivery of the certificates or other instruments, if any, representing the Units so purchased, duly endorsed; provided that if (x) any 
  

 9 

 
of the conditions set forth in Section 5.1 exists or (y) such purchase of Units would result in a Financing Default, in each case which prohibits such cash payment (either directly or
indirectly as a result of the prohibition of a related cash dividend or distribution) (each a “Cash Payment Restriction”), the portion of the cash payment so prohibited may be made, to the extent such payment is not prohibited, by
the Company’s delivery of a junior subordinated promissory note (which shall be subordinated and subject in right of payment to the prior payment of any debt outstanding under the senior Financing Agreements and any modifications, renewals,
extensions, replacements and refunding of all such indebtedness); provided that no dividends, distributions or payments shall be made with respect to the Company’s Class A units prior to payment in full of the Junior Subordinated
Note (as defined) of the Company of the Company (a “Junior Subordinated Note”) in a principal amount equal to the balance of the purchase price, payable within ten days after the Cash Payment Restriction no longer exists, and
bearing interest payable (and compounded to the extent not so paid) as of the last day of each year at the interest rate payable under the senior financing credit facilities of the Company or its Subsidiaries (as applicable) from time to time, and
all such accrued and unpaid interest payable on the date of the payment of principal (or, if applicable, the last installment of principal), with payments to be applied in the order of: (A) first to any enforcement costs incurred by Executive
or Executive’s Group, (B) second to interest and (C) third to principal. In the event that a Cash Payment Restriction exists as a result of a Financing Default and the Company or its Subsidiaries is refinancing, modifying, reviewing,
extending, replacing or refunding the indebtedness that resulted in the Financing Default then the Company shall use commercially reasonable efforts to cause such refinanced, modified, reviewed, extended, replaced or refunded indebtedness not to
include any terms that would result in a Financing Default with respect to the payment for the Units as contemplated herein. The Company shall have the right set forth in clause (i) of the first sentence of this Section 5.2 whether or not
the member of Executive’s Group selling such Units is an obligor of the Company. The principal of, and accrued interest on, any such Junior Subordinated Note may be prepaid in whole or in part at any time at the option of the Company. To the
extent that the Company is prohibited from paying accrued interest, that is required to be paid on any Junior Subordinated Note prior to maturity, due to the existence of any Cash Payment Restriction, such interest shall be cumulated, compounded
calendar quarterly, and accrued until and to the extent that such Cash Payment Restriction no longer exists, at which time such accrued interest shall be immediately paid. Notwithstanding any other provision in this Agreement, the Company may elect
to pay the purchase price hereunder in shares or other equity securities of one of its direct or indirect Subsidiaries with a fair market value equal to the applicable purchase price, provided that such Subsidiary promptly repurchases such
shares or other equity securities for cash equal to the applicable purchase price or a Junior Subordinated Note (if otherwise permissible hereunder) with a principal amount equal to the applicable purchase price. 

5.3 Repayment of Proceeds. If a Restrictive Covenant Violation occurs or the Company discovers after a termination of employment
that grounds existed for Cause at the time thereof, then Executive shall be required to pay to the Company, within 10 business days’ of the Company’s request to Executive therefor, an amount equal to the excess, if any, of (A) the
aggregate after-tax proceeds (taking into account all amounts of tax that would be recoverable upon a claim of loss for payment of such proceeds in the year of repayment) Executive received upon the sale or other disposition of, or distributions in
respect of, Executive’s Units over (B) the aggregate Cost of such Units. 
  

 10 

 6. Restrictive Covenant Violation; Competitive Activity. 

(a) Executive acknowledges and recognizes the highly competitive nature of the businesses of the Company and its
Affiliates and accordingly agrees, in his capacity as an investor and equityholder in the Company and its Affiliates, to the provisions of Appendix A to this Agreement. Executive acknowledges and agrees that the Company’s remedies at law for a
breach or threatened breach of any of the provisions of Appendix A would be inadequate and the Company would suffer irreparable damages as a result of such breach or threatened breach. In recognition of this fact, Executive agrees that, in the event
of such a breach or threatened breach, in addition to any remedies at law, the Company, without posting any bond, shall be entitled to cease making any payments or providing any benefit otherwise required by this Agreement and obtain equitable
relief in the form of specific performance, temporary restraining order, temporary or permanent injunction or any other equitable remedy which may then be available. 

(b) Executive shall be deemed to have engaged in “Competitive Activity” if Executive engages in any
conduct that would be a Restrictive Covenant Violation if it occurred during the relevant periods specified in Appendix A (even if such conduct occurs after the relevant periods). For the avoidance of doubt, any conduct that constitutes Competitive
Activity but not a Restrictive Covenant Violation shall not be prohibited hereby. 
 7. Miscellaneous. 

7.1 Transfers. Prior to the transfer of Units to a Permitted Transferee, Executive shall deliver to the Company a written
agreement of the proposed transferee (a) evidencing such Person’s undertaking to be bound by the terms of this Agreement and (b) acknowledging that the Units transferred to such Person will continue to be Units for purposes of this
Agreement in the hands of such Person. Any transfer or attempted transfer of Units in violation of any provision of this Agreement or the Securityholders Agreement shall be void, and the Company shall not record such transfer on its books or treat
any purported transferee of such Units as the owner of such Units for any purpose. 
 7.2 Recapitalizations, Exchanges, Etc.,
Affecting Units. The provisions of this Agreement shall apply, to the full extent set forth herein with respect to Units, to any and all securities of the Company or any successor or assign of the Company (whether by merger, consolidation, sale
of assets or otherwise) which may be issued in respect of, in exchange for, or in substitution of the Units, by reason of any dividend payable in units, issuance of units, combination, recapitalization, reclassification, merger, consolidation or
otherwise. 
 7.3 Executive’s Employment by the Company. Nothing contained in this Agreement shall be deemed to
obligate the Company or any Subsidiary of the Company to employ Executive in any capacity whatsoever or to prohibit or restrict the Company (or any such Subsidiary) from terminating the employment of Executive at any time or for any reason
whatsoever, with or without Cause. 
 7.4 Cooperation. Executive agrees to cooperate with the Company in taking action
reasonably necessary to consummate the transactions contemplated by this Agreement. 
  

 11 

 7.5 Binding Effect. The provisions of this Agreement shall be binding upon and accrue
to the benefit of the parties hereto and their respective heirs, legal representatives, successors and assigns; provided, however, that no Transferee shall derive any rights under this Agreement unless and until such Transferee has executed and
delivered to the Company a valid undertaking and becomes bound by the terms of this Agreement; and provided further that the Sponsor is a third party beneficiary of this Agreement and shall have the right to enforce the provisions hereof.

 7.6 Amendment; Waiver. This Agreement may be amended only by a written instrument signed by the parties hereto. No
waiver by any party hereto of any of the provisions hereof shall be effective unless set forth in a writing executed by the party so waiving. 

7.7 Governing Law; Jurisdiction. This Agreement shall be governed by and construed and enforced in accordance with the laws of the
State of Delaware applicable to contracts made and to be performed therein. Any suit, action or proceeding with respect to this Agreement, or any judgment entered by any court in respect of any thereof, shall be brought in any court of competent
jurisdiction in the State of New York or the State of Delaware, and each of the Company and the members of Executive’s Group hereby submits to the exclusive jurisdiction of such courts for the purpose of any such suit, action, proceeding or
judgment. Each of the members of Executive’s Group and the Company hereby irrevocably waives (i) any objections which it may now or hereafter have to the laying of the venue of any suit, action or proceeding arising out of or relating to

(i) Executive will not, within eighteen months following the termination of Executive’s employment with Company or
its subsidiaries (the “Post-Termination Period”) or during the period of Executive’s employment with the Company or its subsidiaries (collectively with the Post-Termination Period, the “Restricted Period”), accept an
employment or consulting relationship (or own or have any financial interest in), directly or indirectly, with any entity which derives at least 10% of its revenue from engaging in the business of home respiratory therapy, home infusion therapy, and
home medical equipment that is competitive with the Company and its Subsidiaries within the United States (a “Competitive Business”). 

(ii) During the Restricted Period, Executive will not initiate or respond to communications with any of the employees of
the Company or its subsidiaries who earned annually $50,000 or more as a Company or subsidiary employee during the twelve-month period prior to the termination of such employee’s employment with the Company or subsidiary, for the purpose of
soliciting such employee, or facilitating the hiring of any such employee, to work for any other business, individual, partnership, firm, corporation, or other entity. 

(iii) During the Restricted Period, Executive will not influence or attempt to influence customers of the Company or its
subsidiaries or any of its present or future subsidiaries or affiliates, either directly or indirectly, to divert their business to any individual, partnership, firm, corporation or other entity then in competition with the business of the Company
or any subsidiary or affiliate of the Company. 
 (iv) During the Restricted Period, Executive will not, other
than as required by law or by order of a court or other competent authority, make or publish, or cause any other person to make or publish, any statement that is disparaging or that reflects negatively upon the Company or its affiliates, or that is
or reasonably would be expected to be damaging to the reputation of the Company or any subsidiary or affiliate of the Company. 

Notwithstanding anything to the contrary in this Agreement, Executive may, directly or indirectly own, solely as an investment, securities
of any person engaged in a Competitive Business which are publicly traded on a national or regional stock exchange or on the over-the-counter market if Executive (i) is not a controlling person of, or a member of a group which controls, such
person and (ii) does not, directly or indirectly, own 5% or more of any class of securities of such person. 

 (b) It is expressly understood and agreed that although Executive and the Company consider
the restrictions contained in this Appendix A to be reasonable, if a final judicial determination is made by a court of competent jurisdiction, that the time or territory or any other restriction contained in this Appendix A is an unenforceable
restriction against Executive, the provisions of this Appendix A shall not be rendered void but shall be deemed amended to apply as to such maximum time and territory and to such maximum extent as such court may judicially determine or indicate to
be enforceable. Alternatively, if any court of competent jurisdiction finds that any restriction contained in this Agreement is unenforceable, and such restriction cannot be amended so as to make it enforceable, such finding shall not affect the
enforceability of any of the other restrictions contained herein. 
 (c) The period of time during which the provisions of this
Appendix A shall be in effect shall be extended by the length of time during which Executive is in breach of the terms hereof as determined by any court of competent jurisdiction on the Company’s application for injunctive relief.

activities and operations of the Company, its subsidiaries or affiliates and/or any third party that has disclosed or provided any of same to the Company on a confidential basis (“Confidential Information”) without the prior written
authorization of the Board. 
 (b) “Confidential Information” shall not include any information that is
(a) generally known to the industry or the public other than as a result of Executive’s breach of this covenant or any breach of other confidentiality obligations by third parties; (b) made legitimately available to Executive by a
third party without breach of any confidentiality obligation; or (c) required by law to be disclosed (including via subpoena); provided that Executive shall give prompt Notice to the Company of such requirement of law, disclose no more
information than is so required, and cooperate with any attempts by the Company to obtain a protective order or similar treatment. 

(c) Except as required by law, Executive will not disclose to anyone, other than Executive’s immediate family and legal or financial
advisors, the existence or contents of this Agreement; provided, that Executive may disclose to any prospective future employer the notice provisions of this Appendix A provided they agree to maintain the confidentiality of such terms.

Executive shall (x) cease and not thereafter commence use of any Confidential Information or intellectual property (including without limitation, any patent, invention, copyright, trade secret, trademark, trade name, logo, domain name or other
source indicator) owned or used by the Company, its subsidiaries or affiliates; (y) immediately destroy, delete, or return to the Company, at the Company’s option, all originals and copies in any form or medium (including memoranda, books,

 3.2 Additional Investment Representations. Executive represents and warrants that:

 (a) Executive’s financial situation is such that Executive can afford to bear the economic risk of holding the Units for
an indefinite period of time, has adequate means for providing for Executive’s current needs and personal contingencies, and can afford to suffer a complete loss of Executive’s investment in the Units; 

(b) Executive’s knowledge and experience in financial and business matters are such that Executive is capable of evaluating the
merits and risks of the investment in the Units; 
 (c) Executive understands that the Units are a speculative investment which
involves a high degree of risk of loss of Executive’s investment therein, there are substantial restrictions on the transferability of the Units and, on the Closing Date and for an indefinite period following the Closing, there will be no
public market for the Units and, accordingly, it may not be possible for Executive to liquidate Executive’s investment in case of emergency, if at all; 

(d) the terms of this Agreement provide that if under certain circumstances Executive ceases to be an employee of the Company or its
Subsidiaries, the Company and its Affiliates have the right to repurchase the Units at a price which may, under certain circumstances, be less than the Fair Market Value thereof; 

(e) Executive understands and has taken cognizance of all the risk factors related to the purchase of the Units and, other than as set
forth in this Agreement, no representations or warranties have been made to Executive or Executive’s representatives concerning the Units or the Company or their prospects or other matters; 

(f) Executive has been given the opportunity to examine all documents and to ask questions of, and to receive answers from, the Company
and its representatives concerning the Company and its Subsidiaries, the Securityholders Agreement, the Company’s organizational documents and the terms and conditions of the purchase of the Units and to obtain any additional information which
Executive deems necessary; 
 (g) all information which Executive has provided to the Company and the Company’s
representatives concerning Executive and Executive’s financial position is complete and correct as of the date of this Agreement; and 

(h) Executive is or is not an “accredited investor” within the meaning of Rule 501(a) under the Securities Act, as indicated on
Executive’s Master Signature Page.

	4.	Certain Sales and Forfeitures Upon Termination of Employment; Variations to Securityholders Agreement. 

4.1 Put Option. 

(a) Prior to the occurrence of the initial Public Offering, if Executive’s employment with the Company and its Subsidiaries
terminates due to the death of Executive or is terminated by the Company or any of its Subsidiaries as a result of the Disability of Executive, Executive and Executive’s Permitted Transferees (hereinafter sometimes collectively referred to as
the “Executive’s Group”) shall have the right, subject to the provisions of Section 5 hereof, for 180 days following the date that is 210 days after the Termination Date, to sell to the Company (the “Put
Right”), and the Company shall be required to purchase (subject to the provisions of Section 5 hereof), on one occasion from each member of Executive’s Group, all (but not less than all) of the number of Vested Units then held by
Executive’s Group that equals all Vested Units collectively held by Executive’s Group at a price per Unit equal to the Fair Market Value of such Units (measured as of the date that the relevant election to purchase such Units is delivered
(the “Valuation Date”)). In order to exercise its rights with respect to the Vested Units pursuant to this Section 4.1(a), Executive’s Group shall also be required to simultaneously exercise any similar rights it may have
with respect to any other units of the Company held by Executive’s Group in accordance with the terms of the agreements pursuant to which such other units were acquired from the Company. 

(b) If Executive’s Group desires to exercise the Put Right, the members of Executive’s Group shall send one written notice to
the Company setting forth such members’ intention to collectively sell all of their Vested Units pursuant to Section 4.1(a), which notice shall include the signature of each member of Executive’s Group. Subject to the provisions of
Section 5.1, the closing of the purchase shall take place at the principal office of the Company on a date specified by the Company no later than the 60th day after the giving of such notice. 

4.2 Call Options. 

(a) If (1) Executive’s employment with the Company and its Subsidiaries is terminated for any reason (whether by the Company or
Executive, or as a result of death or Disability), (2) a Restrictive Covenant Violation occurs or (3) Executive engages in a Competitive Activity (as defined in Section 6 of this Agreement) not constituting a Restrictive Covenant
Violation without the consent of the Board, then the Company shall have the right, for 210 days following the relevant event described in clause (1), (2) or (3) (or, in the case of clause (2) or (3) only, the date on which the
Board has actual knowledge (or reasonably should have knowledge) thereof) or (z) the date that is six months and one day after the date on which Executive became vested in the applicable Units, to purchase (the “Call Option”),
and each member of Executive’s Group shall be required to sell to the Company, all Vested Units then held by such member of Executive’s Group (it being understood that if Units of any class subject to repurchase hereunder may be
repurchased at different prices, the Company may elect to repurchase only the portion of the Units of such class subject to repurchase hereunder at the lower price) at a price per Unit equal to the applicable purchase price determined as follows:

 (i) Termination with Cause or Restrictive Covenant Violation. If Executive’s employment with the
Company and its Subsidiaries is terminated by the Company or any of its Subsidiaries with Cause (or by Executive at a time when grounds exist for Cause, regardless of any notice, cure or waiting period thereunder) or in the event of a Restrictive
Covenant Violation, the purchase price per Unit will be the lesser of (A) Fair Market Value thereof (measured as of the Valuation Date) and (B) Cost; 
  

 7 

 (ii) Death or Disability; Termination without Cause; Resignation for
Constructive Termination. If Executive’s employment with the Company and its Subsidiaries is terminated (w) by the Company or any of its Subsidiaries as a result of the Disability of Executive, (x) due to the death of Executive,
(y) by the Company without Cause or (z) by Executive as a result of a Constructive Termination, the purchase price per Unit will be the Fair Market Value thereof (measured as of the Valuation Date); 

(iii) Voluntary Resignation. If Executive’s employment with the Company and its Subsidiaries is terminated by
Executive (other than as a result of Constructive Termination), the purchase price per Unit will be: 
 (A) if
such termination occurs on or before the second anniversary of the Closing Date, the lesser of (A) Fair Market Value thereof (measured as of the Valuation Date) and (B) Cost; or 

(B) if such termination occurs after the Closing Date, the Fair Market Value thereof; and 

(iv) Competitive Activity. In the event Executive engages in a Competitive Activity not constituting a Restrictive
Covenant Violation without the consent of the Board, the purchase price per Unit will be the Fair Market Value thereof (measured as of the Valuation Date). 

The Call Option in respect of Vested Units (except in respect of any event described in Sections 4.2(a)(i) or 4.2(a)(iii)(A)) shall expire upon the
occurrence of a Public Offering. 
 (b) If Executive’s employment with the Company and its Subsidiaries is terminated for
any reason, all Unvested Units will be forfeited (or, to the extent a forfeiture is not permissible under applicable law for any reason, the Unvested Units shall be subject to the Call Option in Section 4.2(a) with the purchase price per
Unvested Unit equal to the lesser of (A) Fair Market Value thereof (measured as of the Valuation Date) and (B) Cost). 

(c) If the Company desires to exercise its Call Option pursuant to this Section 4.2, the Company shall send written notice to each
member of Executive’s Group of its intention to purchase Units, specifying the number of Units to be purchased (the “Call Notice”). Subject to the provisions of Section 5, the closing of the purchase shall take place at
the principal office of the Company on a date specified by the Company no later than the 30th day after the giving of the Call Notice. 

(d) Notwithstanding the foregoing, if the Company elects not to exercise its Call Option pursuant to this Section 4.2, the Sponsor
may elect to purchase such Units at any time on the same terms and conditions set forth in this Section 4.2 by providing written notice to each member of Executive’s Group of its intention to purchase Units. 

 

 8 

 4.3 Obligation to Sell Several. If there is more than one member of Executive’s
Group, the failure of any one member thereof to perform its obligations hereunder shall not excuse or affect the obligations of any other member thereof, and the closing of the purchases from such other members by the Company shall not excuse, or
constitute a waiver of its rights against, the defaulting member. 
  

	5.	Certain Limitations on the Company’s Obligations to Purchase Units. 

5.1 Prohibition of Purchases. Notwithstanding anything to the contrary contained herein, the Company shall not be obligated to
purchase any Units at any time pursuant to Section 4, regardless of whether it has delivered a notice of its election to purchase any such Units, to the extent that the purchase of such Units or the payment to the Company or one of its
Subsidiaries of a cash dividend or distribution by a Subsidiary of the Company that is necessary to fund such purchase (together with any other purchases of Units pursuant to Section 4 or pursuant to similar provisions in agreements with other
employees of the Company and its Subsidiaries of which the Company has at such time been given or has given notice and together with cash dividends and distributions necessary to fund such other purchases) would result in a violation of any law,
statute, rule, regulation, policy, order, writ, injunction, decree or judgment promulgated or entered by any federal, state, local or foreign court or governmental authority applicable to the Company or any of its Subsidiaries or any of its or their
property. The Company shall, within fifteen days of learning of any such fact, so notify the members of Executive’s Group that it is not obligated to purchase Units hereunder. 

5.2 Payment for Units. If at any time the Company elects or is required to purchase any Units pursuant to Section 4, the
Company shall pay the purchase price for the Units it purchases (i) first, by the cancellation of any indebtedness, if any, owing from Executive to the Company or any of its Subsidiaries (which indebtedness shall be applied pro rata against the
proceeds receivable by each member of Executive’s Group receiving consideration in such repurchase) and (ii) then, by the Company’s delivery of a check or wire transfer of immediately available funds for the remainder of the purchase
price, if any, against delivery of the certificates or other instruments, if any, representing the Units so purchased, duly endorsed; provided that if (x) any of the conditions set forth in Section 5.1 exists or (y) such purchase of
Units would result in a Financing Default, in each case which prohibits such cash payment (either directly or indirectly as a result of the prohibition of a related cash dividend or distribution) (each a “Cash Payment Restriction”), the
portion of the cash payment so prohibited may be made, to the extent such payment is not prohibited, by the Company’s delivery of a junior subordinated promissory note (which shall be subordinated and subject in right of payment to the prior
payment of any debt outstanding under the senior Financing Agreements and any modifications, renewals, extensions, replacements and refunding of all such indebtedness) of the Company (a “Junior Subordinated Note”) in a principal amount
equal to the balance of the purchase price, payable within ten days after the Cash Payment Restriction no longer exists, and bearing interest payable (and compounded to the extent not so paid) as of the last day of each year at the interest rate
payable under the senior financing credit facilities of the Company or its Subsidiaries (as applicable) from time to time, and all such accrued and unpaid interest payable on the date of the payment of principal (or, if applicable, the last
installment of principal), with 
  

 9 

 
payments to be applied in the order of: first to any enforcement costs incurred by Executive or Executive’s Group, second to interest and third to principal. The Company shall have the right
set forth in clause (i) of the first sentence of this Section 5.2 whether or not the member of Executive’s Group selling such Units is an obligor of the Company. The principal of, and accrued interest on, any such Junior Subordinated
Note may be prepaid in whole or in part at any time at the option of the Company. To the extent that the Company is prohibited from paying accrued interest, that is required to be paid on any Junior Subordinated Note prior to maturity, due to the
existence of any Cash Payment Restriction, such interest shall be cumulated, compounded calendar quarterly, and accrued until and to the extent that such Cash Payment Restriction no longer exists, at which time such accrued interest shall be
immediately paid. Notwithstanding any other provision in this Agreement, the Company may elect to pay the purchase price hereunder in shares or other equity securities of one of its direct or indirect Subsidiaries with a fair market value equal to
the applicable purchase price, provided that such Subsidiary promptly repurchases such shares or other equity securities for cash equal to the applicable purchase price or a Junior Subordinated Note (if otherwise permissible hereunder) with a
principal amount equal to the applicable purchase price. 
 5.3 Repayment of Proceeds. If a Restrictive Covenant
Violation occurs or the Company discovers after a termination of employment that grounds existed for Cause at the time thereof, then Executive shall be required to pay to the Company, within 10 business days’ of the Company’s request to
Executive therefor, an amount equal to the excess, if any, of (A) the aggregate after-tax proceeds (taking into account all amounts of tax that would be recoverable upon a claim of loss for payment of such proceeds in the year of repayment)
Executive received upon the sale or other disposition of, or distributions in respect of, Executive’s Units over (B) the aggregate Cost of such Units. 
  

	6.	Restrictive Covenant Violation; Competitive Activity. 

(a) Executive acknowledges and recognizes the highly competitive nature of the businesses of the Company and its Affiliates and
accordingly agrees, in his capacity as an investor and equityholder in the Company and its Affiliates, to the provisions of Appendix A to this Agreement. Executive acknowledges and agrees that the Company’s remedies at law for a breach or
threatened breach of any of the provisions of Appendix A would be inadequate and the Company would suffer irreparable damages as a result of such breach or threatened breach. In recognition of this fact, Executive agrees that, in the event of such a
breach or threatened breach, in addition to any remedies at law, the Company, without posting any bond, shall be entitled to cease making any payments or providing any benefit otherwise required by this Agreement and obtain equitable relief in the
form of specific performance, temporary restraining order, temporary or permanent injunction or any other equitable remedy which may then be available. 

(b) Executive shall be deemed to have engaged in “Competitive Activity” if Executive engages, in any conduct that would
be a Restrictive Covenant Violation if it occurred during the relevant periods specified in Appendix A (even if such conduct occurs after the relevant periods). For the avoidance of doubt, any conduct that constitutes Competitive Activity but not a
Restrictive Covenant Violation shall not be prohibited hereby, but instead shall serve to provide that the Call Option may be exercised pursuant to Section 4.2 hereof. 

 

 10 

	7.	Miscellaneous. 

 7.1
Transfers. Prior to the transfer of Units to a Permitted Transferee, Executive shall deliver to the Company a written agreement of the proposed transferee (a) evidencing such Person’s undertaking to be bound by the terms of this
Agreement and (b) acknowledging that the Units transferred to such Person will continue to be Units for purposes of this Agreement in the hands of such Person. Any transfer or attempted transfer of Units in violation of any provision of this
Agreement or the Securityholders Agreement shall be void, and the Company shall not record such transfer on its books or treat any purported transferee of such Units as the owner of such Units for any purpose. 

7.2 Recapitalizations, Exchanges, Etc., Affecting Units. The provisions of this Agreement shall apply, to the full extent set
forth herein with respect to the Units, to any and all securities of the Company or any successor or assign of the Company (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in exchange for, or in
substitution of the Units, by reason of any dividend payable in Units, issuance of Units, combination, recapitalization, reclassification, merger, consolidation or otherwise. 

7.3 Executive’s Employment by the Company. Nothing contained in this Agreement shall be deemed to obligate the Company or any
Subsidiary of the Company to employ Executive in any capacity whatsoever or to prohibit or restrict the Company (or any such Subsidiary) from terminating the employment of Executive at any time or for any reason whatsoever, with or without Cause.

 7.4 Cooperation. Executive agrees to cooperate with the Company in taking action reasonably necessary to consummate

executed and delivered to the Company a valid undertaking and becomes bound by the terms of this Agreement; and provided further that the Sponsor is a third party beneficiary of this Agreement and shall have the right to enforce the provisions
hereof. 
 7.6 Amendment; Waiver. This Agreement may be amended only by a written instrument signed by the parties
hereto. No waiver by any party hereto of any of the provisions hereof shall be effective unless set forth in a writing executed by the party so waiving.

State of Delaware applicable to contracts made and to be performed therein. Any suit, action or proceeding with respect to this Agreement, or any judgment entered by any court in respect of any thereof, shall be brought in any court of competent
jurisdiction in the State of New York or the State of Delaware, and each of the Company and the members of Executive’s Group hereby submits to the exclusive jurisdiction of such courts for the purpose of any such suit, action, proceeding or
judgment. Each of the members of Executive’s Group and the Company hereby irrevocably waives (i) any objections which it may now or hereafter have to the laying of the venue of any suit, action or proceeding

	A.	The individual named above and signatory hereto (the “Executive”) agrees to be bound by: 

 

	 	(1)	the Amended and Restated Limited Liability Company Agreement of Apria Holdings LLC, a Delaware limited liability company (the “Company”), in the
form attached hereto (the “LLC Agreement”), as a Member and an Employee Member (each, as defined in the LLC Agreement); 

  

	 	(2)	the Management Unit Subscription Agreement (Class B Units and Class C Units), between the Company and the Executive, dated as of the Commitment Date, in the form
attached hereto (the “Promote Agreement”); and 

  

	 	(3)	the Amended and Restated Securityholders Agreement, among the Company and the other parties thereto (including the Executive), in the form attached hereto (the
“Securityholders Agreement”), as an Employee (as defined in the Securityholders Agreement). 

  

	B.	The Executive and the Company agree that the following information is hereby incorporated by reference into the Promote Agreement: 

 

						
	 Class of Units
	  	Number of Units	  	Cash Paid
(if any)
	 Class B Units
	  		  	$	0
	 Class C Units
	  		  	$	0

  

	C.	Notwithstanding anything to the contrary in the LLC Agreement, Executive’s initial distributions in respect of each Class B Unit (whether or not then vested) shall
be foregone and shall instead be distributed in respect of other Units until such time as the cumulative foregone distributions in respect of each of such Class B Units equals $0.33 (the “Excluded Amount Per Unit”). Once the Excluded
Amount Per Unit has been foregone, Executive shall be entitled to a share of all subsequent distributions in connection with each Class B Unit calculated in the same manner as other Class B Units; provided that the Excluded Amount Per Unit shall
remain foregone. The intent of the foregoing exclusion is to ensure that the Class B Units do not participate in a distribution of any profits or increase in the value of the Company created prior to the Closing Date, such that the Class B Units
qualify as “profits interests” under applicable tax laws. 

  

	D.	The Executive agrees that, upon the request of the Company, Executive shall promptly and duly execute and deliver such further instruments and documents and take such
further actions as the Company may reasonably request for the purpose of giving effect to the foregoing. 

  

	E.	The “Closing Date” for the transactions contemplated by the Promote Agreement shall be

 Appendix A 

Restrictive Covenants 

1. Confidentiality; Non-Compete; Non-Solicit; Non-Disparagement. 

(a) For the purposes of this Appendix A, any reference to the “Company” shall mean the Company and its Subsidiaries,
collectively. In view of the fact that Executive’s work for the Company brings Executive into close contact with many confidential affairs of the Company not readily available to the public, and plans for further developments, Executive agrees:

 (i) Executive will not at any time (whether during or after Executive’s employment with the Company)
(x) retain or use for the benefit, purposes or account of Executive or any other person; or (y) disclose, divulge, reveal, communicate, share, transfer or provide access to any person outside the Company (other than its professional
advisers who are bound by confidentiality obligations), any non-public, proprietary or confidential information —including without limitation trade secrets, know-how, research and development, software, databases, inventions, processes,
formulae, technology, designs and other intellectual property, information concerning finances, investments, profits, pricing, costs, products, services, vendors, customers, clients, partners, investors, personnel, compensation, recruiting,
training, advertising, sales, marketing, promotions, government and regulatory activities and approvals — concerning the past, current or future business, activities and operations of the Company, its subsidiaries or affiliates and/or any third
party that has disclosed or provided any of same to the Company on a confidential basis (“Confidential Information”) without the prior written authorization of the Board. 

(ii) “Confidential Information” shall not include any information that is (a) generally known to the
industry or the public other than as a result of Executive’s breach of this covenant or any breach of other confidentiality obligations by third parties; (b) made legitimately available to Executive by a third party without breach of any
confidentiality obligation; or (c) required by law to be disclosed (including via subpoena); provided that Executive shall give prompt Notice to the Company of such requirement of law, disclose no more information than is so required,
and cooperate with any attempts by the Company to obtain a protective order or similar treatment. 
 (iii) Except
as required by law, Executive will not disclose to anyone, other than Executive’s immediate family and legal or financial advisors, the existence or contents of this Agreement; provided, that Executive may disclose to any prospective
future employer the notice provisions of this Appendix A provided they agree to maintain the confidentiality of such terms. 

(iv) Upon termination of Executive’s employment with the Company for any reason, Executive shall (x) cease and
not thereafter commence use of any Confidential Information or intellectual property (including without limitation, any patent, invention, copyright, trade secret, trademark, trade name, logo, domain name or other source indicator) owned or used by
the Company, its subsidiaries or affiliates; (y)

 
immediately destroy, delete, or return to the Company, at the Company’s option, all originals and copies in any form or medium (including memoranda, books, papers, plans, computer files,
letters and other data) in Executive’s possession or control (including any of the foregoing stored or located in Executive’s office, home, laptop or other computer, whether or not Company property) that contain Confidential Information or
otherwise relate to the business of the Company, its affiliates and subsidiaries, except that Executive may retain only those portions of any personal notes, notebooks and diaries that do not contain any Confidential Information and his rolodex (or
other physical or electronic address book); and (z) fully cooperate with the Company regarding the delivery or destruction of any other Confidential Information not within Executive’s possession or control of which Executive is or becomes
aware. 
 (b) Executive acknowledges and recognizes the highly competitive nature of the businesses of the Company and its
affiliates and accordingly agrees as follows: 
 (i) Executive will not, within one year following the
termination of his employment with the Company (the “Post-Termination Period”) or during Executive’s employment (collectively with the Post-Termination Period, the “Restricted Period”), accept an employment or
consulting relationship (or own or have any financial interest in), directly or indirectly, with any entity engaged in the business of home respiratory therapy, home infusion therapy, and home medical equipment, within the United States. 

(ii) During the Restricted Period, Executive will not influence or attempt to influence customers of the Company or its
subsidiaries or any of its present or future subsidiaries or affiliates, either directly or indirectly, to divert their business to any individual, partnership, firm, corporation or other entity then in competition with the business of the Company
or any subsidiary or affiliate of the Company. 
 (iii) Executive will not, within two years following the
termination of his employment with the Company, initiate or respond to communications with any of the employees of the Company or its subsidiaries who earned annually $50,000 or more as a Company or subsidiary employee during the twelve-month period
prior to the termination of such employee’s employment with the Company, for the purpose of soliciting such employee, or facilitating the hiring of any such employee, to work for any other business, individual, partnership, firm, corporation,
or other entity; and 
 Notwithstanding anything to the contrary in this Agreement, Executive may, directly or indirectly own,
solely as an investment, securities of any Person which are publicly traded on a national or regional stock exchange or on the over-the-counter market if Executive (i) is not a controlling person of, or a member of a group which controls, such
person and (ii) does not, directly or indirectly, own 5% or more of any class of securities of such Person. 
 (c)
Executive will not, other than as required by law or by order of a court or other competent authority, make or publish, or cause any other person to make or publish, any statement that is disparaging or that reflects negatively upon the Company or
its affiliates, or that is or reasonably would be expected to be damaging to the reputation of the Company or its affiliates. 
  

 A-2 

 (d) It is expressly understood and agreed that although Executive and the Company consider
the restrictions contained in this Appendix A to be reasonable, if a final judicial determination is made by a court of competent jurisdiction, that the time or territory or any other restriction contained in this Agreement is an unenforceable
restriction against Executive, the provisions of this Agreement shall not be rendered void but shall be deemed amended to apply as to such maximum time and territory and to such maximum extent as such court may judicially determine or indicate to be
enforceable. Alternatively, if any court of competent jurisdiction finds that any restriction contained in this Agreement is unenforceable, and such restriction cannot be amended so as to make it enforceable, such finding shall not affect the
enforceability of any of the other restrictions contained herein. 
 (e) The period of time during which the provisions of this
Appendix A shall be in effect shall be extended by the length of time during which Executive is in breach of the terms hereof as determined by any court of competent jurisdiction on the Company’s application for injunctive relief. 

2. Specific Performance; Survival. 

(a) Executive acknowledges and agrees that the Company’s remedies at law for a breach or threatened breach of any of the provisions
of this Appendix A would be inadequate and the Company would suffer irreparable damages as a result of such breach or threatened breach. In recognition of this fact, Executive agrees that, in the event of such a breach or threatened breach, in
addition to any remedies at law, the Company, without posting any bond, shall be entitled to suspend making any payments or providing any benefit otherwise required by this Agreement and obtain equitable relief in the form of specific performance,
temporary restraining order, temporary or permanent injunction or any other equitable remedy which may then be available. 
 (b)
The provisions of this Appendix A shall survive the termination of Executive’s employment for any reason.
