consummation of the mergers (the &#147;Merger&#148;) that closed effective on
September&nbsp;1, 2005 in accordance with the Agreement and Plan of Merger, made and entered into
as of February&nbsp;28, 2005 and amended as of June&nbsp;23, 2005 by and among the Registrant, Quinton Cardiology Systems, Inc.
(&#147;Quinton&#148;), Rhythm Acquisition Corporation, a wholly-owned subsidiary of Registrant
(&#147;Quinton Merger Sub&#148;), Cardiac Science, Inc. (&#147;Cardiac&#148;) and Heart Acquisition Corporation,
a wholly-owned subsidiary of Registrant (&#147;Cardiac Merger Sub&#148;), Quinton Merger Sub was
merged into Quinton, Quinton as the surviving Corporation of that
merger was merged into the Registrant, and Cardiac Merger Sub was
merged into Cardiac, as a result of which
Cardiac became a wholly owned subsidiary of Registrant. In addition, upon the
consummation of the Merger, the Registrant assumed the obligations of Quinton and Cardiac
under each of the stock plans listed on the fee table for this registration statement and
(i)&nbsp;each option to purchase Quinton common stock outstanding immediately prior to the
effective time of the Merger became an option to purchase a number of shares of the
Registrant&#146;s Common Stock equal to the product of the number of shares of Quinton common
stock subject to the option immediately prior to the Merger multiplied by 0.77184895 at an
exercise price per share equal to the exercise price per share of Quinton common stock
subject to each option divided by 0.77184895; (ii)&nbsp;each purchase right outstanding under the
Quinton 2002 Employee Stock Purchase Plan became the right to purchase 0.77184895 shares of
the Registrant&#146;s common stock on the applicable purchase date at a purchase price determined
based on the lower of 85% of the fair market value of the Registrant&#146;s common stock on the
applicable purchase date and 85% of the fair market value of Quinton common stock at the
beginning of the applicable offering period in effect as of the effective time of the Merger
divided by 0.77184895; and (iii)&nbsp;each option to purchase Cardiac common stock outstanding
immediately prior to the effective time of the Merger became an option to purchase a number
or shares of the Registrant&#146;s Common Stock equal to the product of the number of shares of
Cardiac common stock subject to the option immediately prior to the effective time of the
Merger multiplied by .10 at an exercise price per share equal to the exercise price per
share of Cardiac common stock subject to each option divided by .10.

EXPLANATORY NOTE
Upon
consummation of the mergers (the "Merger") that closed effective on
September 1, 2005 in accordance with the Agreement and Plan of Merger, made and entered into
as of February 28, 2005 and amended as of June 23, 2005 by and among the Registrant, Quinton Cardiology Systems, Inc.
("Quinton"), Rhythm Acquisition Corporation, a wholly-owned subsidiary of Registrant
("Quinton Merger Sub"), Cardiac Science, Inc. ("Cardiac") and Heart Acquisition Corporation,
a wholly-owned subsidiary of Registrant ("Cardiac Merger Sub"), Quinton Merger Sub was
merged into Quinton, Quinton as the surviving Corporation of that
merger was merged into the Registrant, and Cardiac Merger Sub was
merged into Cardiac, as a result of which
Cardiac became a wholly owned subsidiary of Registrant. In addition, upon the
consummation of the Merger, the Registrant assumed the obligations of Quinton and Cardiac
under each of the stock plans listed on the fee table for this registration statement and
(i) each option to purchase Quinton common stock outstanding immediately prior to the
effective time of the Merger became an option to purchase a number of shares of the
Registrant's Common Stock equal to the product of the number of shares of Quinton common
stock subject to the option immediately prior to the Merger multiplied by 0.77184895 at an
exercise price per share equal to the exercise price per share of Quinton common stock
subject to each option divided by 0.77184895; (ii) each purchase right outstanding under the
Quinton 2002 Employee Stock Purchase Plan became the right to purchase 0.77184895 shares of
the Registrant's common stock on the applicable purchase date at a purchase price determined
based on the lower of 85% of the fair market value of the Registrant's common stock on the
applicable purchase date and 85% of the fair market value of Quinton common stock at the
beginning of the applicable offering period in effect as of the effective time of the Merger
divided by 0.77184895; and (iii) each option to purchase Cardiac common stock outstanding
immediately prior to the effective time of the Merger became an option to purchase a number
or shares of the Registrant's Common Stock equal to the product of the number of shares of
Cardiac common stock subject to the option immediately prior to the effective time of the
Merger multiplied by .10 at an exercise price per share equal to the exercise price per
share of Cardiac common stock subject to each option divided by .10.

Item 4. DESCRIPTION OF SECURITIES
Not applicable.
Item 5. INTERESTS OF NAMED EXPERTS AND COUNSEL
None.
Item 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS
The Registrant's certificate of incorporation provides that the Registrant will indemnify
its directors and executive officers to the fullest extent permitted by law. The
Registrant's bylaws also permit the Registrant to secure insurance on behalf of any officer
or director for any liability arising out of his or her actions in this capacity,
regardless of whether the bylaws would permit indemnification.
The Registrant will enter into agreements to indemnify its directors and executive officers, in
addition to the indemnification provided for in the Registrant's certificate of incorporation and
bylaws. These agreements, among other things, will provide for indemnification of directors and
executive officers for many expenses including attorneys' fees, judgments, fines and settlement
amounts incurred by any such person in any action or proceeding, including any action by or in the
right of the
II-1
Table of Contents
Registrant, arising out of such person's services as a director or executive officer of the
Registrant or any of the Registrant's subsidiaries or any other company or enterprise to which the
person provided services at the Registrant's request.
Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify a
director, officer, employee or agent who was or is a party, or is threatened to be made a party to
any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason
of the fact that he was a director, officer, employee or agent of the corporation or was serving at
the request of the corporation against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in connection with such action
if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the
best interests of the corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be
permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing
provisions, the Registrant has been informed that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act and is therefore
unenforceable.

Item 9. UNDERTAKINGS
(a) The undersigned Registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective
amendment to this Registration Statement:
(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;
(ii) To reflect in the prospectus any facts or events arising after the effective date of this
Registration Statement (or the most recent post-effective amendment thereof) which, individually or
in the aggregate, represent a fundamental change in the information set forth in this Registration
Statement; and
(iii) To include any material information with respect to the plan of distribution not
previously disclosed in this Registration Statement or any material change to such information in
this Registration Statement;
provided
,
however
, that paragraphs (1)(i) and (1)(ii) above do not apply if the
information required to be included in a post-effective amendment by those paragraphs is contained
in periodic reports filed or furnished by the Registrant pursuant to Section 13 or Section 15(d) of
the Exchange Act that are incorporated by reference in this Registration Statement.
(2) That, for the purpose of determining any liability under the Securities Act, each such
post-effective amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities
being registered which remain unsold at the termination of the offering.
(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability
under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a)
or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in
this Registration Statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
II-3
Table of Contents
(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to
directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions,
or otherwise, the Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or proceeding) is asserted
by such director, officer or controlling person in connection with the securities being registered,
the Registrant will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.
