Registration Statement covering the Registrable Securities for a selling stockholder resale
offering to be made on a continuous basis pursuant to Rule 415. Each Registration Statement shall
be on Form S-3 (except if the Company is not then eligible to register for resale the Registrable
Securities on Form S-3, in which case such registration shall be on another appropriate form in
accordance herewith). The Company shall cause each Registration Statement to become effective and
remain effective as provided herein. The Company shall use its best efforts to cause each
Registration Statement to be declared effective under the Securities Act as promptly as possible
after the filing thereof, but in any event no later than the Effectiveness Date. The Company shall
use its reasonable commercial efforts to keep each Registration Statement continuously effective
under the Securities Act until the date which is the earlier date of when (i) all Registrable
Securities covered by such Registration Statement have been sold or (ii) all Registrable Securities
covered by such Registration Statement may be sold immediately without registration under the
Securities Act and without volume restrictions pursuant to Rule 144(k), as determined by the
counsel to the Company pursuant to a written opinion letter to such effect, addressed and
acceptable to the Company’s transfer agent and the affected Holders (each, an “Effectiveness
Period”).



          (b) If: (i) the Registration Statement is not filed on or prior to the Filing Date; (ii) the
Registration Statement is not declared effective by the Commission by the Effectiveness Date; (iii)
after the Registration Statement is filed with and declared effective by the Commission, the
Registration Statement ceases to be effective (by suspension or otherwise) as to all Registrable
Securities to which it is required to relate at any time prior to the expiration of the
Effectiveness Period (without being succeeded immediately by an additional registration statement
filed and declared effective) for a period of time which shall exceed 30 days in the aggregate per
year or more than 20 consecutive calendar days (defined as a period of 365 days commencing on the
date the Registration Statement is declared effective); or (iv) the Common Stock is not listed or
quoted on any Trading Market, or is suspended from trading on its principal Trading Market and is
not available for trading on any other Trading Market, for a period of three (3) consecutive
Trading Days (provided the Company shall not have been able to cure such trading suspension within
30 days of the notice thereof or list the Common Stock on another Trading Market); (any such
failure or breach being referred to as an “Event,” and for purposes of clause (i) or (ii) the date
on which such Event occurs, or for purposes of clause (iii) the date which such 30 day or 20
consecutive day period (as the case may be) is exceeded, or for purposes of clause (iv) the date on
which such three (3) Trading Day period is exceeded, being referred to as “Event Date”), then until
the applicable Event is cured, the Company shall pay to



Registration Rights Agreement


3









 






each Holder an amount in cash, as liquidated damages and not as a penalty, equal to 1.0% for
each thirty (30) day period (prorated for partial periods) on a daily basis of the original
principal amount of the Note. While such Event continues, such liquidated damages shall be paid
not less often than each thirty (30) days. Any unpaid liquidated damages as of the date when an
Event has been cured by the Company shall be paid within three (3) days following the date on which
such Event has been cured by the Company. Notwithstanding the foregoing, no liquidated damages
shall be payable to any Holder with respect to an Event if such Holder proximately caused the Event
to occur.



          (c) Within three business days of the Effectiveness Date, the Company shall cause its counsel
to issue a blanket opinion in the form attached hereto as Exhibit A, to the transfer agent stating
that the shares are subject to an effective registration statement and can be reissued free of
restrictive legend upon notice of a sale by the Purchaser and confirmation by the Purchaser that it
has complied with the prospectus delivery requirements, provided that the Company has not advised
the transfer agent orally or in writing that the opinion has been withdrawn. Copies of the blanket
opinion required by this Section 2(c) shall be delivered to the Purchaser within the time frame set
forth above.



     3. Registration Procedures. If and whenever the Company is required by the provisions hereof
to effect the registration of any Registrable Securities under the Securities Act, the Company
will, as expeditiously as possible:



          (a) prepare and file with the Commission a Registration Statement with respect to such
Registrable Securities, respond as promptly as possible to any comments received from the
Commission, and use its best efforts to cause such Registration Statement to become and remain
effective for the Effectiveness Period with respect thereto, and promptly provide to the Purchaser
copies of all filings and Commission letters of comment relating thereto;



          (b) prepare and file with the Commission such amendments and supplements to such Registration
Statement and the Prospectus used in connection therewith as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all Registrable Securities
covered by such Registration Statement and to keep such Registration Statement effective until the
expiration of the Effectiveness Period applicable to such Registration Statement;



          (c) furnish to the Purchaser such number of copies of the Registration Statement and the
Prospectus included therein (including each preliminary Prospectus) as the Purchaser reasonably may
request to facilitate the public sale or disposition of the Registrable Securities covered by such
Registration Statement;



          (d) use its best efforts to register or qualify the Purchaser’s Registrable Securities covered
by such Registration Statement under the securities or “blue sky” laws of such jurisdictions within
the United States as the Purchaser may reasonably request, provided, however, that the Company
shall not for any such purpose be required to qualify generally to transact business as a foreign
corporation in any jurisdiction where it is not so qualified or to consent to general service of
process in any such jurisdiction;



Registration Rights Agreement


4









 






          (e) list the Registrable Securities covered by such Registration Statement with any securities
exchange on which the Common Stock of the Company is then listed;



          (f) immediately notify the Purchaser at any time when a Prospectus relating thereto is
required to be delivered under the Securities Act, of the happening of any event of which the
Company has knowledge as a result of which the Prospectus contained in such Registration Statement,
as then in effect, includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing; and



          (g) make available for inspection by the Purchaser and any attorney, accountant or other agent
retained by the Purchaser, all publicly available, non-confidential financial and other records,
pertinent corporate documents and properties of the Company, and cause the Company’s officers,
directors and employees to supply all publicly available, non-confidential information reasonably
requested by the attorney, accountant or agent of the Purchaser.



     4. Registration Expenses. All expenses relating to the Company’s compliance with Sections 2
and 3 hereof, including, without limitation, all registration and filing fees, printing expenses,
fees and disbursements of counsel and independent public accountants for the Company, fees and
expenses (including reasonable counsel fees) incurred in connection with complying with state
securities or “blue sky” laws, fees of the NASD, transfer taxes, fees of transfer agents and
registrars, reasonable fees of, and disbursements incurred by, one counsel for the Holders are
called “Registration Expenses”. All selling commissions applicable to the sale of Registrable
Securities, including any fees and disbursements of any special counsel to the Holders beyond those
included in Registration Expenses, are called “Selling Expenses.” The Company shall only be
responsible for all Registration Expenses. The Holder shall be responsible for all Selling
Expenses.



     5. Indemnification.



          (a) In the event of a registration of any Registrable Securities under the Securities Act
pursuant to this Agreement, the Company will indemnify and hold harmless each Holder, and its
officers, directors and each other person, if any, who controls such Holder within the meaning of
the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which
such Holder, or such persons may become subject under the Securities Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are
based upon any untrue statement or alleged untrue statement of any material fact contained in any
Registration Statement under which such Registrable Securities were registered under the Securities
Act pursuant to this Agreement, any preliminary Prospectus or final Prospectus contained therein,
or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse such Holder, and each such person for any
reasonable legal or other expenses incurred by them in connection with investigating or defending
any such loss, claim, damage, liability or action; provided, however, that the
Company will not be liable in any such case if and to the extent that any such loss, claim, damage
or liability arises out of or is based upon an untrue statement or



Registration Rights Agreement


5









 






alleged untrue statement or omission or alleged omission so made in conformity with
information furnished by or on behalf of the Purchaser or any such person in writing specifically
for use in any such document.



          (b) In the event of a registration of the Registrable Securities under the Securities Act
pursuant to this Agreement, the Purchaser will indemnify and hold harmless the Company, and its
officers, directors and each other person, if any, who controls the Company within the meaning of
the Securities Act, against all losses, claims, damages or liabilities, joint or several, to which
the Company or such persons may become subject under the Securities Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are
based upon any untrue statement or alleged untrue statement of any material fact which was
furnished in writing by the Purchaser to the Company expressly for use in (and such information is
contained in) the Registration Statement under which such Registrable Securities were registered
under the Securities Act pursuant to this Agreement, any preliminary Prospectus or final Prospectus
contained therein, or any amendment or supplement thereof, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the Company and each
such person for any reasonable legal or other expenses incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action, provided,
however, that the Purchaser will be liable in any such case if and only to the extent that
any such loss, claim, damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission so made in conformity with information
furnished in writing to the Company by or on behalf of the Purchaser specifically for use in any
such document. Notwithstanding the provisions of this paragraph, the Purchaser shall not be
required to indemnify any person or entity in excess of the amount of the aggregate net proceeds
received by the Purchaser in respect of Registrable Securities in connection with any such
registration under the Securities Act.



          (c) Promptly after receipt by a party entitled to claim indemnification hereunder (an
“Indemnified Party”) of notice of the commencement of any action, such Indemnified Party shall, if
a claim for indemnification in respect thereof is to be made against a party hereto obligated to
indemnify such Indemnified Party (an “Indemnifying Party”), notify the Indemnifying Party in
writing thereof, but the omission so to notify the Indemnifying Party shall not relieve it from any
liability which it may have to such Indemnified Party other than under this Section 5(c) and shall
only relieve it from any liability which it may have to such Indemnified Party under this Section
5(c) if and to the extent the Indemnifying Party is prejudiced by such omission. In case any such
action shall be brought against any Indemnified Party and it shall notify the Indemnifying Party of
the commencement thereof, the Indemnifying Party shall be entitled to participate in and, to the
extent it shall wish, to assume and undertake the defense thereof with counsel satisfactory to such
Indemnified Party, and, after notice from the Indemnifying Party to such Indemnified Party of its
election so to assume and undertake the defense thereof, the Indemnifying Party shall not be liable
to such Indemnified Party under this Section 5(c) for any legal expenses subsequently incurred by
such Indemnified Party in connection with the defense thereof; if the Indemnified Party retains its
own counsel, then the Indemnified Party shall pay all fees, costs and expenses of such counsel,
provided, however, that, if the defendants in any such action include both the
Indemnified Party and the Indemnifying Party and the Indemnified Party shall have reasonably
concluded that there may be reasonable



Registration Rights Agreement


6









 







defenses available to it which are different from or additional to those available to the
Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to
conflict with the interests of the Indemnifying Party, the Indemnified Party shall have the right
to select one separate counsel and to assume such legal defenses and otherwise to participate in
the defense of such action, with the reasonable expenses and fees of such separate counsel and
other expenses related to such participation to be reimbursed by the Indemnifying Party as
incurred.



          (d) In order to provide for just and equitable contribution in the event of joint liability
under the Securities Act in any case in which either (i) the Purchaser, or any officer, director or
controlling person of the Purchaser, makes a claim for indemnification pursuant to this Section 5
but it is judicially determined (by the entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact that this Section 5
provides for indemnification in such case, or (ii) contribution under the Securities Act may be
required on the part of the Purchaser or such officer, director or controlling person of the
Purchaser in circumstances for which indemnification is provided under this Section 5; then, and in
each such case, the Company and the Purchaser will contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject (after contribution from others) in such
proportion so that the Purchaser is responsible only for the portion represented by the percentage
that the public offering price of its securities offered by the Registration Statement bears to the
public offering price of all securities offered by such Registration Statement, provided,
however, that, in any such case, (A) the Purchaser will not be required to contribute any
amount in excess of the public offering price of all such securities offered by it pursuant to such
Registration Statement; and (B) no person or entity guilty of fraudulent misrepresentation (within
the meaning of Section 10(f) of the Act) will be entitled to contribution from any person or entity
who was not guilty of such fraudulent misrepresentation.



     6. Representations and Warranties.



          (a) The Common Stock is registered pursuant to Section 12(b) or 12(g) of the Exchange Act and,
except with respect to certain matters which the Company has disclosed to the Purchaser on
Schedule 12(u) to the Security Agreement, the Company has timely filed all proxy
statements, reports, schedules, forms, statements and other documents required to be filed by it
under the Exchange Act. The Company has filed (i) its Annual Report on Form 10-K for its fiscal
year ended March 31, 2007and (ii) its Quarterly Reports on Form 10-Q for the fiscal quarters ended
June 30, 2006, September 30, 2006, and December 31, 2006 (collectively, the “SEC Reports”). Each
SEC Report was, at the time of its filing, in substantial compliance with the requirements of its
respective form and none of the SEC Reports, nor the financial statements (and the notes thereto)
included in the SEC Reports, as of their respective filing dates, contained any untrue statement of
a material fact or omitted to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were made, not
misleading. The financial statements of the Company included in the SEC Reports comply as to form
in all material respects with applicable accounting requirements and the published rules and
regulations of the Commission or other applicable rules and regulations with respect thereto. Such
financial statements have been prepared in accordance with generally accepted accounting principles
(“GAAP”) applied on a consistent basis during the periods involved (except (i) as may be otherwise
indicated in such financial statements or the notes



Registration Rights Agreement


7









 







thereto or (ii) in the case of unaudited interim statements, to the extent they may not
include footnotes or may be condensed) and fairly present in all material respects the financial
condition, the results of operations and the cash flows of the Company and its subsidiaries, on a
consolidated basis, as of, and for, the periods presented in each such SEC Report.



          (b) The Common Stock is listed or quoted, as applicable, for trading on the American Stock
Exchange and satisfies all requirements for the continuation of such listing or quotation, as
applicable, and the Company shall do all things necessary for the continuation of such listing or
quotation, as applicable. The Company has not received any notice that its Common Stock will be
delisted from or no longer be quoted on, as applicable, the American Stock Exchange (except for
prior notices which have been fully remedied) or that the Common Stock does not meet all
requirements for the continuation of such listing or quotation, as applicable.



          (c) Neither the Company, nor any of its affiliates, nor any person acting on its or their
behalf, has directly or indirectly made any offers or sales of any security or solicited any offers
to buy any security under circumstances that would cause the offering of the Securities pursuant to
the Security Agreement to be integrated with prior offerings by the Company for purposes of the
Securities Act which would prevent the Company from selling the Common Stock pursuant to Rule 506
under the Securities Act, or any applicable exchange-related stockholder approval provisions, nor
will the Company or any of its affiliates or subsidiaries take any action or steps that would cause
the offering of the Common Stock to be integrated with other offerings (other than such concurrent
offering to the Purchaser).



          (d) The Note and the Warrants and the shares of Common Stock that the Purchaser may acquire
pursuant to the Note and the Warrants are all restricted securities under the Securities Act as of
the date of this Agreement. The Company will not issue any stop transfer order or other order
impeding the sale and delivery of any of the Registrable Securities at such time as such
Registrable Securities are registered for public sale or an exemption from registration is
available, except as required by federal or state securities laws.



          (e) The Company understands the nature of the Registrable Securities issuable upon the
conversion of the Note and the exercise of each Warrant and recognizes that the issuance of such
Registrable Securities may have a potential dilutive effect. The Company specifically acknowledges
that its obligation to issue the Registrable Securities is binding upon the Company and enforceable
regardless of the dilution such issuance may have on the ownership interests of other shareholders
of the Company.



          (f) Except for agreements made in the ordinary course of business, there is no agreement that
has not been filed with the Commission as an exhibit to a registration statement or to a form
required to be filed by the Company under the Exchange Act, the breach of which could reasonably be
expected to have a material and adverse effect on the Company and its subsidiaries, or would
prohibit or otherwise interfere with the ability of the Company to enter into and perform any of
its obligations under this Agreement in any material respect.



Registration Rights Agreement


8









 





          (g) The Company will at all times have authorized and reserved a sufficient number of shares
of Common Stock for the full conversion of the Note and the full exercise of the Warrants.



          (h) The Company shall provide written notice to each Holder of (i) the occurrence of each
Discontinuation Event (as defined below) and (ii) the declaration of effectiveness by the SEC of
each Registration Statement required to be filed hereunder, in each case within one (1) business
day of the date of each such occurrence and/or declaration.



     7. Miscellaneous.



          (a) Remedies. In the event of a breach by the Company or by a Holder, of any of their
respective obligations under this Agreement, each Holder or the Company, as the case may be, in
addition to being entitled to exercise all rights granted by law and under this Agreement,
including recovery of damages, will be entitled to specific performance of its rights under this
Agreement.



          (b) No Piggyback on Registrations. Except as and to the extent set forth on Schedule 7(b)
hereto, neither the Company nor any of its security holders (other than the Holders in such
capacity pursuant hereto) may include securities of the Company in any Registration Statement other
than the Registrable Securities, and the Company shall not after the date hereof enter into any
agreement providing any such right for inclusion of shares in the Registration Statement to any of
its security holders. Except as and to the extent specified in Schedule 7(b) hereto, the
Company has not previously entered into any agreement granting any registration rights with respect
to any of its securities to any Person that have not been fully satisfied.



          (c) Compliance. Each Holder covenants and agrees that it will comply with the prospectus
delivery requirements of the Securities Act as applicable to it in connection with sales of
Registrable Securities pursuant to any Registration Statement.



          (d) Discontinued Disposition. Each Holder agrees by its acquisition of such Registrable
Securities that, upon receipt of a notice from the Company of the occurrence of a Discontinuation
Event (as defined below), such Holder will forthwith discontinue disposition of such Registrable
Securities under the applicable Registration Statement until such Holder’s receipt of the copies of
the supplemented Prospectus and/or amended Registration Statement or until it is advised in writing
(the “Advice”) by the Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that are incorporated or
deemed to be incorporated by reference in such Prospectus or Registration Statement. The Company
may provide appropriate stop orders to enforce the provisions of this paragraph. For purposes of
this Agreement, a “Discontinuation Event” shall mean (i) when the Commission notifies the Company
whether there will be a “review” of such Registration Statement and whenever the Commission
comments in writing on such Registration Statement (the Company shall provide true and complete
copies thereof and all written responses thereto to each of the Holders); (ii) any request by the
Commission or any other Federal or state governmental authority for amendments or supplements to
such Registration Statement or Prospectus or for additional information; (iii) the issuance by the
Commission of any stop order suspending the effectiveness of such Registration Statement



Registration Rights Agreement

covering any or all of the Registrable Securities or the initiation of any Proceedings for
that purpose; (iv) the receipt by the Company of any notification with respect to the suspension of
the qualification or exemption from qualification of any of the Registrable Securities for sale in
any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; and/or (v)
the occurrence of any event or passage of time that makes the financial statements included in such
Registration Statement ineligible for inclusion therein or any statement made in such Registration
Statement or Prospectus or any document incorporated or deemed to be incorporated therein by
reference untrue in any material respect or that requires any revisions to such Registration
Statement, Prospectus or other documents so that, in the case of such Registration Statement or
Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not misleading.



          (e) Piggy-Back Registrations. If at any time during the applicable Effectiveness Period there
is not an effective Registration Statement covering all of the Registrable Securities required to
be covered during such Effectiveness Period and the Company shall determine to prepare and file
with the Commission a registration statement relating to an offering for its own account or the
account of others under the Securities Act of any of its equity securities, other than on Form S-4
or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to
equity securities to be issued solely in connection with any acquisition of any entity or business
or equity securities issuable in connection with stock option or other employee benefit plans, then
the Company shall send to each Holder written notice of such determination and, if within fifteen
(15) days after receipt of such notice, any such Holder shall so request in writing, the Company
shall include in such registration statement all or any part of such Registrable Securities such
Holder requests to be registered, to the extent the Company may do so without violating
registration rights of others which exist as of the date of this Agreement, subject to customary
underwriter cutbacks applicable to all holders of registration rights and subject to obtaining any
required consent of any selling stockholder(s) to such inclusion under such registration statement.



          (f) Amendments and Waivers. The provisions of this Agreement, including the provisions of
this sentence, may not be amended, modified or supplemented, and waivers or consents to departures
from the provisions hereof may not be given, unless the same shall be in writing and signed by the
Company and the Holders of a majority of the then outstanding Registrable Securities.



          (g) Notices. Any notice or request hereunder may be given to the Company or the Purchaser at
the respective addresses set forth below or as may hereafter be specified in a notice designated as
a change of address under this Section 7(g). Any notice or request hereunder shall be given by
registered or certified mail, return receipt requested, hand delivery, overnight mail, Federal
Express or other national overnight next day carrier (collectively, “Courier”) or telecopy
(confirmed by mail). Notices and requests shall be, in the case of those by hand delivery, deemed
to have been given when delivered to any party to whom it is addressed, in the case of those by
mail or overnight mail, deemed to have been given three (3) business days after the date when
deposited in the mail or with the overnight mail carrier, in the case of a Courier, the next

Re:     Chad Therapeutics, Inc. Registration Statement on Form [S-3]




Ladies and Gentlemen:




     As counsel to Chad Therapeutics, Inc. , a                      corporation (the “Company”), we have
been requested to render our opinion to you in connection with the resale by the individuals or
entitles listed on Schedule A attached hereto (the “Selling Stockholders”), of an aggregate
of                      shares (the “Shares”) of the Company’s Common Stock.



     A Registration Statement on Form [S-3] under the Securities Act of 1933, as amended (the
“Act”), with respect to the resale of the Shares was declared effective by the Securities and
Exchange Commission on [date]. Enclosed is the Prospectus dated [date]. We understand that the Shares are to be offered and sold in the manner described in the Prospectus.



     Based upon the foregoing, upon request by the Selling Stockholders at any time while the
registration statement remains effective, it is our opinion that the Shares have been registered
for resale under the Act and new certificates evidencing the Shares upon their transfer or
re-registration by the Selling Stockholders may be issued without restrictive legend. We will
advise you if the registration statement is not available or effective at any point in the future.



Very truly yours,




[Company counsel]
