Exhibit 10.1

FIRST AMENDMENT

TO CREDIT AGREEMENT

This First Amendment to Credit Agreement (this “Amendment”) is entered into as
of January 25, 2012, by and among RESMED INC., a Delaware corporation
(“Borrower”), each lender from time to time party to the Credit Agreement
(defined below; collectively, “Lenders” and individually, a “Lender”), UNION
BANK, N.A., as Administrative Agent (in such capacity, “Administrative Agent”),
Swing Line Lender (in such capacity, “Swing Line Lender”) and L/C Issuer (in
such capacity, “L/C Issuer”), and HSBC BANK USA, NATIONAL ASSOCIATION, as
Syndication Agent (in such capacity, “Syndication Agent”).

RECITALS

Administrative Agent and Syndication Agent (collectively, “Agent Parties” and
individually, an “Agent Party”), Swing Line Lender, L/C Issuer and the Lenders
(collectively, “Lender Parties” and individually, a “Lender Party”), and
Borrower are parties to that certain Credit Agreement dated as of February 10,
2011, as amended, restated, modified or supplemented from time to time (the
“Credit Agreement”). The parties desire to amend the Credit Agreement in
accordance with the terms of this Amendment. Unless otherwise defined herein,
all initially capitalized terms in this Amendment shall be as defined in the
Credit Agreement.

NOW, THEREFORE, the parties agree as follows:

1. Schedule 2.01 of the Credit Agreement is deleted in its entirety and replaced
with Schedule 2.01 attached hereto.

2. No course of dealing on the part of the Agent Parties, the Lender Parties, or
their officers, nor any failure or delay in the exercise of any right under the
Loan Documents by any Agent Party or Lender Party, shall operate as a waiver
thereof, and any single or partial exercise of any such right shall not preclude
any later exercise of any such right. Any Agent Party’s or Lender Party’s
failure at any time to require strict performance by Borrower of any provision
of any Loan Document shall not affect any right of Lender Parties and Agent
Parties thereafter to demand strict compliance with and performance of such
provision.

3. The Credit Agreement, as amended hereby, shall be and remain in full force
and effect in accordance with its respective terms and hereby is ratified and
confirmed in all respects. Except as expressly set forth herein, the execution,
delivery, and performance of this Amendment shall not operate as a waiver of, or
as an amendment of, any right, power, or remedy of any Agent Party or Lender
Party under the Credit Agreement, as in effect prior to the date hereof. Upon
the effectiveness of this Amendment, all references in the Loan Documents to the
“Credit Agreement” shall be deemed to refer to the Credit Agreement, as amended
by this Amendment.

4. Borrower represents and warrants that the representations and warranties
contained in Article V of the Credit Agreement are true and correct in all
material respects as of the date of this Amendment (except such representations
and warranties which are by their terms expressly limited to an earlier date, in
which case the same were true and correct in all material respects as of such
earlier date), and that, after giving effect to this Amendment, no Event of
Default has occurred and is continuing.

5. As a condition to the effectiveness of this Amendment, Administrative Agent
shall have received, in form and substance reasonably satisfactory to
Administrative Agent, the following:

(a) this Amendment, duly executed by Borrower;

(b) an Amended and Restated Promissory Note in favor of each Lender;

(c) an Affirmation of Unconditional Guaranty, duly executed by each Guarantor;

(d) an Officer’s Certificate, duly executed by Borrower and each Guarantor;

--------------------------------------------------------------------------------

(e) payment by Borrower of the fees set forth in that certain $400,000,000
Senior Secured Revolving Credit Facility Fee Letter by and between
Administrative Agent and Borrower dated as of November 3, 2011, which may be
debited from any of Borrower’s accounts;

(f) all reasonable, invoiced costs and expenses of the Administrative Agent
incurred through the date of this Amendment, plus such additional amounts of
such costs and expenses as shall constitute its reasonable estimate of such
costs and expenses incurred or to be incurred by it through the closing
proceedings (provided that such estimate shall not thereafter preclude a final
settling of accounts between Borrower and Administrative Agent), all of which
may be debited from any of Borrower’s accounts; and

(g) such other documents, and completion of such other matters, as
Administrative Agent may reasonably deem necessary or appropriate.

6. This Amendment may be executed in two or more counterparts, each of which
shall be deemed an original, but all of which together shall constitute one
instrument.
