4

to Executive on the Closing Date (except as provided in this paragraph below), the number and classes of “Initial Class A-2 Units” and “Class B Units” set forth on Executive’s Master Signature Page in exchange (a) in the case of the Class A-2 Units, for the cash purchase price set forth on Executive’s Master Signature Page and (b) in the case of the Class B Units, for services performed for the Company and its Subsidiaries by Executive. Furthermore, for a period of six months following the Closing Date, Executive shall have the right, but not the obligation, to subscribe for and agree to acquire, and the Company hereby agrees to issue to Executive upon written notice from Executive of his election to purchase, an additional number of Class A-2 Units, up to the number of “Additional Class A-2 Units” set forth on Executive’s Master Signature Page, in exchange for the cash purchase price per Unit set forth on the Executive’s Master Signature Page.

(a) Catchup for Class A-2 Units. Notwithstanding anything to the contrary in the LLC Agreement, Executive’s distributions in respect of each Class A-2 Unit in excess of $1.00 per Class A-2 Unit 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 such Class A-2 Unit equals $0.10 (the “Delayed Amount Per Class A-2 Unit”).

Thereafter, Executive shall be entitled to receive distributions in connection with each Class A-2 Unit calculated in the same manner as other Class A-2 Units. The intent of the foregoing exclusion is to ensure that the Executive’s Class A-2 Units do not participate in a distribution of any profits or increase in the value of the Company created prior to the Closing Date to the extent exceeding Executive’s $1.00 per Class A-2 Unit capital contribution (except and until distributions in excess of such $1.00 exceed $0.10 per Class A-2 Unit distributable to current Class A-2 Unitholders other than Executive), such that the interests in excess of the Executive’s capital contribution on the Class A-2 Units qualify as “profits interests” on the date of the conversion under applicable tax laws.

(b) Catchup for Class B Units. 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 such Class B Unit equals $0.10 (the “Delayed Amount Per Class B Unit”). Once the Delayed Amount Per Class B Unit has been foregone, Executive shall then be entitled to receive 100% of all subsequent distributions to holders of Units until Executive shall have received distributions in respect of this sentence per Unit equal to the Delayed Amount Per Class B Unit. Thereafter, Executive shall be entitled to receive distributions in connection with each Class B Unit calculated in the same manner as other Class B Units. 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” on the date of the conversion under applicable tax laws.

5

(c) Preemptive Rights.

(i) Notwithstanding anything to the contrary in the Securityholders Agreement, at any time that the Company (after the Closing Date and prior to the first Public Offering or any Termination Date) proposes to issue or sell to any Person any common membership units (“Common Equity”) or other equity securities or any securities convertible into or exchangeable for any such common membership units or other equity securities (other than: (i) in connection with any Public Offering (or any restructuring related to a Public Offering), (ii) pursuant to any present or future employee, officer or director benefit plan or program of or assumed by the Company or any of its Subsidiaries, (iii) as consideration in any merger, consolidation, acquisition for stock, business combination or any similar extraordinary transaction or (iv) the issuance of Common Equity or other equity securities as a dividend or distribution to all or substantially all holders of Common Equity or other equity securities, or a subdivision or combination of Common Equity or other equity securities or a reclassification of (or similar action with respect to) Common Equity or other equity securities into a greater or lesser number of Common Equity or other equity securities available to all holders of the applicable class of Common Equity), Executive at such time shall be afforded the opportunity to acquire from the Company for the same price (net of any underwriting discounts or sales commissions) and on the same terms as such Common Equity or other equity securities are proposed to be offered (or, to the extent such Common Equity or other equity securities are offered for consideration (or the exercise price of which is to be paid in consideration) other than cash, the cash equivalent thereof) an amount of Common Equity or other equity securities up to the aggregate amount of Common Equity or other equity securities to be offered or sold multiplied by Executive’s percentage ownership interest in the Class A Units.

(ii) If the Company or any of its Subsidiaries proposes to offer or sell Common Equity or other equity securities that are subject to this Section 2.1(c), the Company shall give Executive written notice (a “Subscription Notice”) of its intention, describing the type of such Common Equity or other equity securities, price (or range of prices), anticipated amount of such Common Equity or other equity securities, timing, and other terms upon which the Company proposes to issue or sell the same. Executive shall have 10 days from the date of receipt of a Subscription Notice to notify the Company in writing (a “Participation Notice”) that he intends to exercise his rights provided in this Section 2.1(c) and the amount of such Common Equity or other equity securities Executive desires to purchase, which amount may not exceed the maximum amount calculated pursuant to Section 2.1(c). Such Participation Notice shall constitute a nonbinding indication of interest of Executive to purchase the amount of such Common Equity or other equity securities so specified at the price and other terms set forth in the Company’s notice to Executive. The failure of Executive to respond within such 10-day period shall be deemed to be a waiver of Executive’s rights under this Section 2.1(c) only with respect to the offering described in the applicable Subscription Notice.

(iii) If Executive exercises his rights provided in this Section 2.1(c), the closing of the purchase of the Common Equity or other equity securities with respect to which such right has been exercised shall take place no less than 15 days and no later than 180 days after the giving of the Participation Notice, which period of time shall be extended for a maximum of 60 days in order to comply with applicable laws and

6

regulations (including receipt of any applicable regulatory approvals). The Company and Executive will use commercially reasonable efforts to secure on a timely basis any regulatory approvals or other consents, and to comply with any law or regulation necessary in connection with the issuance, sale and purchase of, such Common Equity or other equity securities.

(iv) Notwithstanding the foregoing provisions of this Section 2.1(c), the Board may cause the Company to proceed with any issuance or sale of Common Equity or other equity securities prior to having complied with such foregoing provisions; provided that the Company will subsequently comply with the other provisions of this Section 2.1(c) subsequent to such issuances on a prompt basis.

(d) Public Offering.

(i) Without limiting the generality of Section 2.10 of the LLC Agreement, in connection with a Public Offering, the Company will offer to Executive the opportunity to effect a Class B Exchange; provided that the equity securities in to which the Class B Units are exchanged will remain subject to the terms and conditions hereof (including, for the avoidance of doubt, Section 4.2 and the vesting terms hereunder).

(ii) Notwithstanding anything to the contrary in the Securityholders Agreement or the LLC Agreement: (A) upon the date that is 180 calendar days after the Company’s first Public Offering, all restrictions on Transfers (as defined in the Securityholders Agreement) of Units shall expire with respect to all of Executive’s Vested Units, including any and all Units acquired by Executive subsequent to the Closing Date (provided that such Units shall be exchanged into common equity of the issuer in such Public Offering prior to any such Transfer); and (B) immediately upon the Company’s first Public Offering, all rights of first refusal upon any Transfers (as defined in the Securityholders Agreement) of Units, shall expire with respect to all of Executive’s Units, including any and all Units acquired by Executive subsequent to the Closing Date.

2.2 The Closing. The closing (the “Closing”) of the grant of Units hereunder shall take place on December 5, 2012. The date of the Closing shall be the “Closing Date”.

2.3 Section 83(b) Election. Within 10 days after the Closing, Executive shall provide the Company with a copy of a completed election under Section 83(b) of the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder in the form of Exhibit A to Executive’s Master Signature Page. Executive shall timely (within 30 days of the Closing) file (via certified mail, return receipt requested) such election with the Internal Revenue Service and shall thereafter notify the Company it has made such timely filing. Executive should consult his tax advisor regarding the consequences of a Section 83(b) election, as well as the receipt, vesting, holding and sale of Units.

11

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.

5.1 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

12

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 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. 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 offers to repurchase 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. In the event the Company terminates Executive for Cause or Executive resigns at a time when grounds for Cause exist (and the Company discovers no later than 30 calendar days after such resignation that grounds existed for Cause at the time thereof and notifies Executive of such fact during 30-day period), 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 Class B Units over (B) the aggregate Cost of such Units. The foregoing shall not apply in respect to any event that occurs after a Public Offering if Executive was employed by the Company at the time of the Public Offering.

(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 of any of the provisions of Appendix A would be inadequate and the Company would suffer irreparable damages as a result of such breach. In recognition of this fact, Executive agrees that, in the event of such a 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, after the Restricted Period (as defined in Appendix A), Executive accepts an employment or consulting relationship (or acquires any financial interest in), directly or indirectly, with a Direct Competitor of the Company. For the purposes of the foregoing, a “Direct Competitor” means any entity that is in direct competition with the business of the Company and which derives at least 20% 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.

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.

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 Permitted Transferee shall derive any rights under this Agreement unless and until such Permitted 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.

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 this Agreement brought in any court of competent jurisdiction in the State of Delaware or the State of New York, (ii) any claim that any such suit, action or proceeding brought in any such court has been brought in any inconvenient forum and (iii) any right to a jury trial.

Notwithstanding the foregoing, immediately prior to, and following, the occurrence (prior to the Termination Date) of a Change of Control in which Blackstone ceases to control (directly, or indirectly through one or more intermediaries or contractual counterparties) the entity that employs Executive, all of the Class B Units that are Unvested Units shall become Vested Units.

Any Unvested Units on a Termination Date shall be immediately forfeited by Executive (or, to the extent a forfeiture is not permissible, such 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).

Appendix A

Restrictive Covenants

(a) 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 twenty-four 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.

A-2

(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.

(a) 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.

A-3

agency, or in any litigation or similar proceeding; provided that prior to making any such required disclosure, Executive shall notify the Company in sufficient time to permit the Company to seek an appropriate protective order.

(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.

(d) 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 Executive’s 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. Notwithstanding the foregoing, Executive may retain Executive’s rolodex and similar address books.

(e) The provisions of Appendix A shall survive the termination of Executive’s employment for any reason.
