7. It is the intention of Apria and Executive in executing this Release that the same shall be effective as a bar to each and every claim, demand and cause of action hereinabove specified. In furtherance of this intention, Apria and Executive hereby expressly waive any and

3

all rights and benefits conferred upon them by the provisions of SECTION 1542 OF THE CALIFORNIA CIVIL CODE and expressly consent that this Release shall be given full force and effect according to each and all of its express terms and provisions, including those related to unknown and unsuspected claims, demands and causes of action, if any, as well as those relating to any other claims, demands and causes of action hereinabove specified. SECTION 1542 provides:

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.”

Apria and Executive, and each of them, acknowledge that either may hereafter discover claims or facts in addition to or different from those which either or both of them now knows or believes to exist with respect to the subject matter of this Release and which, if known or suspected at the time of executing this Release, may have materially affected this settlement. Nevertheless, Apria and Executive each hereby waive any right, claim or cause of action that might arise as a result of such different or additional claims or facts. Apria and Executive each acknowledge that it or he understands the significance and consequence of such release and such specific waiver of SECTION 1542.

8. The terms and conditions of this Release shall remain confidential as between the parties and professional advisers to the parties and neither of them shall disclose them to any other person, except as provided herein or as required by the rules and regulations of the Securities and Exchange Commission (“SEC”) or as otherwise may be required by law or court order. Without limiting the generality of the foregoing, neither Apria nor Executive will respond to or in any way participate in or contribute to any public discussion concerning, or in any way relating to, the execution of this Release or the events which led to its execution. Except as provided above with respect to SEC rules and regulations or as otherwise may be required by law or court order, if inquiry is made of Apria concerning any of the claims released by this Release or relating to Executive’s employment with Apria, Apria shall provide to third parties Executive’s dates of employment with Apria and its predecessors and his job titles during such employment, in accordance with the normal practices of Apria’s human resources department.

9. Executive expressly acknowledges and agrees that, by entering into this Release, he is waiving any and all rights or claims that may have arisen under the Age Discrimination in Employment Act of 1967, as amended, which have arisen on or before the date of execution of this Release. Executive further expressly acknowledges that:

a. He is hereby advised in writing by this Release to consult with an attorney before signing this Release;

b. He was given a copy of this Release on November 29, 2012, and informed that he had until December 27, 2012 to consider this Release, although he is free to execute this Release anytime prior to that date as indicated in Section 20 below; and

4

c. He was informed that he has seven days following the date of his execution of this Release in which to revoke this Release, which revocation may be effected by means of a written notice sent to the General Counsel of Apria at Apria’s corporate headquarters, provided that in all events any revocation must be received by Apria during the seven-day revocation period.

d. Apria and Executive agree that this Release will not become effective or enforceable until the seven-day revocation period has expired without Executive’s having revoked this Release. Moreover, if this Release is revoked, all “Performance-Vesting Units” referered to in the Other Subscription Agreements and the New Subscription Agreement shall immediately be forfeited and canceled with no further action required by any party.

10. Apria and Executive each warrant and represent that neither has heretofore assigned or transferred to any person not a party to this Release any released matter or any part or portion thereof and each shall defend, indemnify and hold harmless the other from and against any claim (including the payment of attorneys’ fees and costs actually incurred whether or not litigation is commenced) based on or in connection with or arising out of any such assignment or transfer made, purported or claimed.

11. Apria and Executive acknowledge that any employment relationship between them (including with any other Apria Releasee) will terminate on the Termination Date, that they have no further employment relationship except as may arise out of this Release and that Executive waives any right or claim to reinstatement as an employee of any Apria Releasee and will not seek employment in the future with Apria, unless by mutual consent. Nothing herein shall be construed as voiding Executive’s entitlement to post-termination payments pursuant to Section 1 above or Apria’s (or any of its affiliates as the case may be) rights pursuant to Sections 7, 8 and 9 of the Employment Agreement. Executive agrees that, following the termination of his employment with Apria, (i) he will, at no cost to him, cooperate with any reasonable request Apria may make for information or assistance with respect to any matter involving Executive during his period of employment, and (ii) he will not at any time, directly or indirectly, disparage Apria or any Apria Releasee or take any action with the intention of injuring the business, prospects or reputation of Apria or any Apria Releasee. Apria, on behalf of itself and the Apria Releasees, agrees that it will use its best efforts to cause its officers and directors not to disparage Executive in any way.

12. This Release shall be incorporated into and made a part of the Employment Agreement as of the date hereof. This Release, together with the Employment Agreement, sets forth the entire agreement and understanding between the parties as to the subject matter hereof and supersedes all prior and contemporaneous oral and written discussions, agreements and understandings of any kind or nature. This Release shall inure to the benefit of and be binding upon the parties hereto and their respective permitted successors and assigns. This Release does not, however, affect Executive’s rights under any Apria retirement, 401(k), or similar benefit plan. This Release also does not modify the provisions of any agreement pursuant to which Executive has been granted equity in Apria or any of its affiliates.

13. If any provision of this Release or the application thereof is held invalid, the invalidity shall not affect the other provisions or applications of this Release which can be given effect without the invalid provisions or applications and to this end the provisions of this Release are declared to be severable.

5

14. This Release and the rights and obligations of the parties hereunder shall be construed and enforced in accordance with, and governed by, the laws of the State of California without regard to principles of conflict of laws.

15. This Release may be executed in counterparts, and each counterpart, when executed, shall have the efficacy of a signed original. Photographic copies of such signed counterparts may be used in lieu of the originals for any purpose.

16. Any dispute or controversy between Executive on the one hand, and Apria (or any other Apria Releasee), on the other hand, in any way arising out of, related to, or connected with this Release or the subject matter hereof, or otherwise in any way arising out of, related to, or connected with Executive’s employment with any Apria Releasee or the termination of Executive’s employment with any Apria Releasee, shall be submitted for resolution by arbitration in accordance with the provisions of the Employment Agreement. APRIA AND EXECUTIVE ACKNOWLEDGE, UNDERSTAND AND AGREE THAT IN THE EVENT OF A DISPUTE UNDER THIS RELEASE, EACH PARTY HAS WAIVED ANY RIGHT TO A JURY TRIAL AND A JUDICIAL RESOLUTION OF THE DISPUTE.

17. No waiver of any breach of any term or provision of this Release shall be construed to be, or shall be, a waiver of any other breach of this Release. No waiver shall be binding unless in writing and signed by the party waiving the breach.

18. In entering this Release, the parties represent that they have relied upon the advice of their attorneys, who are attorneys of their own choice, and that they have read the Release and have had the opportunity to have the Release explained to them by their attorneys, and that those terms are fully understood and voluntarily accepted by them.

19. All parties agree to cooperate fully and to execute any and all supplementary documents and to take all additional actions that may be necessary or appropriate to give full force to the terms and intent of this Release and which are not inconsistent with its terms.

20. Executive hereby declares as follows:

I, Daniel E. Greenleaf, hereby acknowledge that I was given until December 27, 2012 to consider the foregoing Release and voluntarily chose to sign the Release prior to that date.

I have read the foregoing Release and I accept and agree to the provisions it contains and hereby execute it voluntarily with full understanding of its consequences.
