 HEARTSTREAM, INC.
 NONCOMPETITION AGREEMENT



This Non-Competition Agreement (the "Agreement") is made as of  __________, 
199_ by and between Hewlett-Packard Company, a California corporation (the 
"Company'), and ____________ ("Employee").

 Background

A. The Company, Heartstream, Inc., a Delaware corporation  ("Heartstream"), 
Whistler Acquisition Corp., a Delaware corporation and a wholly owned 
subsidiary of the Company ("WAC") have entered into an Agreement and Plan of 
Reorganization dated as of even date (the "Reorganization Agreement"), which 
provides for the merger of WAC with and into Heartstream (the "Merger").

B. Employee is presently an employee of Heartstream.

C. As a condition to the Merger, the Reorganization Agreement contemplates, 
among other things, that Employee enter into this Agreement effective upon 
the Closing of the Merger.

NOW THEREFORE, in consideration of the mutual promises made herein, the 
Company and Employee (collectively referred to as the "Parties") hereby agree 
as follows:

1. Covenant Not to Compete or Solicit.

a. Non-Competition.  In the event Employee ceases to be employed by the 
Company for any or no reason (including a voluntary or involuntary 
termination), Employee shall not, during the period ending two years from the 
Closing of the Merger, directly or indirectly, without the prior written 
consent of the Company engage anywhere in the world in the development, 
marketing or sale of automatic external defibrillators (the "AED Business"), 
including by participating in the financing, operation, management or control 
of any firm, corporation or other business entity that is engaged primarily 
in the AED Business or any division or business unit of any firm, corporation 
or other business entity which division or business unit is primarily engaged 
in the AED Business or have any ownership interest in (except for ownership 
of five percent (5%) or less of any outstanding entity whose securities are 
listed on a national securities exchange) any firm, corporation or business 
that derives greater than ten percent (10%) of its revenues from the AED 
Business.

b. No Solicitation.  In the event Employee ceases to be employed by the 
Company for any or no reason (including a voluntary or involuntary 
termination), Employee shall not, during the period ending two years from the 
Closing of the Merger, directly or indirectly, without the prior written 
consent of the Company (i) solicit, encourage or take any other action which 
is intended to induce any employee of the Company to terminate his or her

employment with the Company, or (ii) disrupt, damage, impair or interfere in 
any manner with the contractual relationship between the Company and any 
customer or supplier of the Company.

c. Separate Covenants.  The covenants contained in Sections 1(a) and 1(b) 
above shall be construed as a series of separate covenants, one for each 
county, city and state of any geographic area where any business is presently 
carried on by the Company.  Except for geographic coverage, each such 
separate covenant shall be identical in terms to the covenant contained in 
Sections 1(a) and 1(b).  If, in any judicial proceeding, a court refuses to 
enforce any of such separate covenants (or any part thereof), then such 
unenforceable covenant (or such part) shall be eliminated from this Agreement 
to the extent necessary to permit the remaining separate covenant (or 
portions thereof) to be enforced.  In the event that the provisions of this 
Section 1 are deemed to exceed the time, geographic or scope limitations 
permitted by applicable law, then such provisions shall be reformed to the 
maximum time, geographic or scope limitations, as the case may be, permitted 
by applicable laws.

d. Acknowledgment.  Employee acknowledges and agrees that this Agreement is 
being entered into as a condition to the consummation of the Reorganization 
Agreement, that as a stockholder of Heartstream he is receiving a substantial 
benefit from the consummation of the Reorganization Agreement which 
constitutes adequate consideration for the covenants set forth above, and 
that the covenants set forth above are intended to protect the value of the 
business acquired by the Company in the Merger.

e. Injunctive Relief.  Employee acknowledges that breach of this Section 1 
would cause irreparable injury to the Company and agrees that in the event of 
such breach, the Company shall be entitled to seek injunction relief without 
the necessity of proving actual damages.

2. Mediation.  Except as provided in Section 1(e) above, all disputes or 
controversies (whether of law or fact) of any nature whatsoever arising from 
or relating to this Agreement and the transactions contemplated hereby shall 
be submitted to mediation prior to commencement of any legal proceeding.

3. Miscellaneous.

a. Severability.  If any portion of this Agreement is held by a court of 
competent jurisdiction to conflict with any federal, state or local law, such 
portion of this Agreement shall be of no force or effect and this Agreement 
shall otherwise remain in full force and effect and be construed as if such 
portion had not been included in this Agreement.

b. No Assignment.  Employee shall not assign this Agreement or any rights or 
obligations under this Agreement. This Agreement shall be binding upon 
Employee's heirs, executors, administrators, and other legal representatives 
and shall be for the benefit of the Company, its successors and its assigns.

Agreement may not be changed or modified, except by an agreement in writing

of California.
