AND WARRANT PURCHASE AGREEMENT

THIS NOTE AND WARRANT PURCHASE AGREEMENT (this “Agreement”) is made as of January 2, 2008 by and among CHAD Therapeutics, Inc., a California corporation (the “Company”), and the investors listed on Exhibit A hereto, each of which is herein referred to as an “Investor.”

THE PARTIES HEREBY AGREE AS FOLLOWS:

SECTION 1

ISSUANCE OF NOTES AND WARRANTS

1.1 Issuance of Notes. Subject to the terms and conditions of this Agreement, at each Closing (as defined below), the Company shall issue and sell to each Investor participating in such Closing a subordinated secured promissory note (each such note, a “Note” and collectively, the “Notes”) in the principal amount (the “Principal Amount”) equal to the amount set forth beneath the caption “Principal Amount” with respect to such Closing set forth opposite such Investor’s name on Exhibit A attached hereto, against payment by such Investor to the Company of the Principal Amount. The Notes shall each be in the form of Exhibit B attached hereto. Capitalized but otherwise undefined terms used herein shall have the meanings provided therefor in the Notes.

1.2 Issuance of Warrants. Subject to the terms and conditions of this Agreement, at the Initial Closing, the Company shall issue to each Investor that has purchased a Note thereunder, with respect to each such Note, a warrant (the “Warrant”), in the form of Exhibit C attached hereto, representing the right to purchase up to that number of shares of common stock of the Company (“Common Stock”) (as adjusted for stock splits, recapitalizations or other similar events) calculated as follows:


number of shares of Common Stock	=	(Principal Amount of the Note issued at the Initial Closing) x (0.30)
issuable upon exercise of the Warrant		Stock Purchase Price

The Warrant shall, unless sooner terminated as provided therein, have a term of five (5) years from the date of issuance and shall be exercisable at an exercise price (subject to adjustment as set forth in the Warrant) equal to the Stock Purchase Price.

1.3 Stock Purchase Price. For purposes of this Agreement, (i) “Stock Purchase Price” shall mean the average of the closing price per share of the Common Stock on the American

Stock Exchange for each of the five (5) business days ending immediately prior to the date of the Initial Closing.

The closing of the purchase and sale of such additional Notes hereunder shall be held at Morrison & Foerster LLP located at 555 West Fifth Street, Suite 3500, Los Angeles, California 90013 on such date or at such other place as is mutually agreeable to the Company and Investors that are identified on Exhibit A (which each such date and place, together with the Initial Closing, are designated as a “Closing”).

2.3 Conditions to All Closings. The several obligations of the Investors to purchase the Notes on the date of any Closing, including the Initial Closing, shall be subject to the prior or concurrent satisfaction of each of the conditions precedent set forth in this Section 2.4:

(a) No Contest, etc. No claim, litigation, arbitration, governmental investigation, injunction, order, proceeding or inquiry shall be pending or threatened which: (i) seeks to enjoin or would be reasonably be expected to materially delay, impose material limitations on, or otherwise prevent the consummation of, or to recover any damages or obtain relief as a result of, the transactions contemplated by or in connection with the Transaction Documents; or (ii) would otherwise be adverse to any of the parties hereto with respect to the transactions contemplated hereby.

(b) No Material Adverse Effect. No event has occurred or condition exists with respect to the Company or any other Person that has resulted in, or could reasonably be expected to result in, a Material Adverse Effect.

2.4 Delivery. At each Closing (i) each Investor participating in such Closing shall deliver to the Company a check or wire transfer of immediately available funds in the amount of such Investor’s Principal Amount with respect to such Closing, and (ii) the Company shall execute and deliver to each such Investor a Note reflecting the name of the Investor, a principal amount equal to such Investor’s Principal Amount and the date of such Closing, and with respect to the Initial Closing, each Investors’ Warrant as contemplated by Section 1.2. Each such Note and Warrant shall be a binding obligation of the Company upon execution thereof by the Company and delivery thereof to an Investor.

SECTION 3

REPRESENTATIONS AND WARRANTIES OF INVESTORS

Each Investor hereby represents, warrants and covenants to the Company as follows:

3.1 Purchase for Own Account. Such Investor represents that it is acquiring the Notes, Warrant and the Common Stock issuable upon exercise of the Warrants (collectively, the “Securities”) solely for investment for such Investor’s own account not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that such Investor has no present intention of selling, granting any participation in, or otherwise distributing the same. The acquisition by such Investor of any of the Securities shall constitute confirmation of the representation by such Investor that such Investor does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to any of the Securities.

3.2 Investment Experience. Such Investor is an officer and director of the Company. Such Investor acknowledges that any investment in the Securities involves a high degree of risk, and represents that it is able, without materially impairing its financial condition, to hold the Securities for an indefinite period of time and to suffer a complete loss of its investment.

3.3 Accredited Investor. Such Investor represents that it is an “accredited investor” within the meaning of Securities and Exchange Commission (“SEC”) Rule 501 of Regulation D, as presently in effect and, for the purpose of Section 25102(f) of the California Corporations Code, he or she is excluded from the count of “purchasers” pursuant to Rule 260.102.13 thereunder].

3.4 Restrictions on Transfer. Such Investor understands that the Securities are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Securities Act of 1933, as amended (the “Act”), only in certain limited circumstances. In this connection, such Investor represents that it is familiar with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Act. SUCH INVESTOR UNDERSTANDS AND ACKNOWLEDGES HEREIN THAT AN INVESTMENT IN THE COMPANY’S SECURITIES INVOLVES AN EXTREMELY HIGH DEGREE OF RISK AND MAY RESULT IN A COMPLETE LOSS OF HIS, HER OR ITS INVESTMENT. Such Investor understands that the Securities have not been and will not be registered under the Act

and have not been and will not be registered or qualified in any state in which they are offered, and thus the Investor will not be able to resell or otherwise transfer his, her or its Securities unless they are registered under the Act and registered or qualified under applicable state securities laws, or an exemption from such registration or qualification is available. Such Investor has no immediate need for liquidity in connection with this investment and does not anticipate that it will need to sell his, her or its Securities in the foreseeable future.

3.5 Further Limitations on Disposition. Without in any way limiting the representations set forth above, such Investor further agrees not to make any disposition of all or any portion of the Securities unless and until the transferee has agreed in writing for the benefit of the Company to be bound by this Section 3 and any other agreement which the purchasers of Warrants are required to execute and deliver in connection with the this Agreement, and:

(a) there is then in effect a registration statement under the Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or

(b) (i) such Investor shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and (ii) if reasonably requested by the Company, such Investor shall have furnished the Company with an opinion of counsel reasonably satisfactory to the Company that such disposition will not require registration of such shares under the Act

SECTION 4

COVENANTS OF THE COMPANY

The Company hereby agrees as follows:

4.1 Security Interest. To secure the prompt payment to Investors of the Notes, Company hereby agrees to assign, pledge and grant to Investors a continuing security interest in and Lien upon all of the Company’s assets, subject to any prior existing Liens.
