Re:   FY 2003 Sales Bonus

DEAR DARRYL:

      The purpose of this letter is to document our previous discussions
regarding the criteria and potential amount of your FY 2003 sales bonus. This
sales bonus is separate from, and in addition to, your one-time Burdick
integration bonus, as well as your MIP participation, for FY 2003.

Your FY 2003 sales bonus will be based on the recorded revenues of all Burdick
products for the year, including the domestic, international, direct and service
portions. Your target for those revenues is $35.0 million. If you qualify for a
bonus, the bonus will be calculated by multiplying a percentage factor by the
revenues achieved, as more fully described below. However, if you do not achieve
at least 90% of your target, you will not qualify for a bonus.

If you achieve between 90% and 105% of your target, the bonus will be calculated
using a factor of 0.100%. If you achieve between 105% and 110% of your target,
the bonus will be calculated using a factor of 0.125%. If you achieve more than
110% of your target, the bonus will be calculated using a factor of 0.150%.

For example, if FY 2003 revenue for Burdick products is $34.3 million, then
34.3/35.0 = 98%. At 98%, a factor of 0.100% is used, which means that your bonus
would be $34,300,000 X 0.100% or $34,300. But if FY 2003 revenue for Burdick
products is $37.8 million, then 37.8/35.0 = 108%. At 108%, a factor of 0.125% is
used, which means that your bonus would be $37,800,000 X 0.125% or $47,250.

Your sales bonus, if any, will be paid in no later than 30-days after the
conclusion of the audit of financial statements and their filing with SEC for
the year ending December 31, 2003. The audited financial statements will be used
to assure the reasonableness of the revenue amount used in computing your bonus.
If the audit and filing with the SEC is not completed by March 31, 2004,
however, the incentive, if any, will be paid during the following month.

Separation of employment (by resignation or termination) prior to March 31, 2004
will result in forfeiture of the bonus payment.

If this is acceptable to you please indicate by signing below.

Re:   Burdick Integration Bonus

Dear Darryl:

We are pleased to confirm your incentive bonus opportunity of $10,000 for the
achievement of the following objectives related to the integration of Burdick,
Inc. into the fold of Quinton Cardiology Systems, Inc. during 2003. Following
are the integration performance targets and financial incentives that have been
set for you:

-     Upgrade sales and marketing staff as appropriate to ensure ability to met
      corporate objectives and sales performance

-     Support Acute Care sales and integration efforts

-     Support international sales and integration efforts, to include aligning
      proper distribution channels; update distribution agreements

This incentive plan is in recognition of your ability, in your role as Vice
President Sales & Marketing, to significantly impact the success of the
integration of Quinton and Burdick. This one-time integration bonus is to
recognize the extra effort required during the first year of our combined
operations and is intended to align your interests with those of the company as
a whole and with those of our shareholders. This integration bonus is in
addition to the Management Incentive Plan, which is outlined separately, in
which you are also eligible to participate.

Payment of the bonus amount is conditioned upon successful completion of the
defined integration performance goals and continued employment through the
period ending December 31, 2003. Determination of whether the integration goals
have been accomplished will be made by the President and/or Chief Financial
Officer of Quinton Cardiology Systems, Inc. Payment of the incentive bonus will
be made in the first quarter of 2004.

This does not create any contractual rights between you and the Company. The
company reserves the right to revise, amend, and/or terminate this incentive
plan at any time without notice. Should there be a separation of employment
prior to December 31, 2003, you are ineligible, and forfeit any right or claim,
to payment of the bonus amount.

We are excited about the combination of Burdick and Quinton, your role in the
newly combined company and the prospect of our mutual success together.

                                        Respectfully,

                                        /s/ John R. Hinson

                             STOCK OPTION AGREEMENT

      Pursuant to your Stock Option Grant Notice (the "Grant Notice") and this
Stock Option Agreement, Quinton Cardiology Systems, Inc. has granted you an
Option outside of its 2002 Stock Incentive Plan (the "Plan"), but, except as
expressly provided otherwise in this Stock Option Agreement, subject to the
terms and conditions of the Plan, to purchase the number of shares of the
Company's Common Stock indicated in your Grant Notice (the "Shares") at the
exercise price indicated in your Grant Notice. Capitalized terms not explicitly
defined in this Stock Option Agreement but defined in the Plan shall have the
same definitions as in the Plan.

      The details of the Option are as follows:

      1.    VESTING AND EXERCISABILITY. Subject to the limitations contained
herein, the Option will vest and become exercisable as provided in your Grant
Notice, provided that vesting will cease upon the termination of your employment
or service relationship with the Company or a Related Company and the unvested
portion of the Option will terminate.

      2.    SECURITIES LAW COMPLIANCE. Notwithstanding any other provision of
this Agreement, you may not exercise the Option unless the Shares issuable upon
exercise are registered under the Securities Act or, if such Shares are not then
so registered, the Company has determined that such exercise and issuance would
be exempt from the registration requirements of the Securities Act. The exercise
of the Option must also comply with other applicable laws and regulations
governing the Option, and you may not exercise the Option if the Company
determines that such exercise would not be in material compliance with such laws
and regulations.

      3.    METHOD OF EXERCISE. You may exercise the Option by giving written
notice to the Company, in form and substance satisfactory to the Company, which
will state your election to exercise the Option and the number of Shares for
which you are exercising the Option. The written notice must be accompanied by
full payment of the exercise price for the number of Shares you are purchasing.
At the discretion of the Plan Administrator, you may make this payment in any
combination of the following: (a) by cash; (b) by check acceptable to the
Company; (c) by using shares of Common Stock you have owned for at least six
months; (d) if the Common Stock is registered under the Exchange Act, by
instructing a broker to deliver to the Company the total payment required; or
(e) by any other method permitted by the Plan Administrator.

      4.    MARKET STANDOFF. By exercising the Option you agree that the Shares
will be subject to the market standoff restrictions on transfer set forth in the
Plan.

      5.    TREATMENT UPON TERMINATION OF EMPLOYMENT OR SERVICE RELATIONSHIP.
The unvested portion of the Option will terminate automatically and without
further notice immediately upon termination of your employment or service
relationship with the Company or a Related Company for any reason ("Termination
of Service"). You may exercise the vested portion of the Option as follows:
<PAGE>
            (a)   General Rule. You must exercise the vested portion of the
Option on or before the earlier of (i) three months after your Termination of
Service and (ii) the Option Expiration Date;

            (b)   Disability. If your employment or service relationship
terminates due to Disability, you must exercise the vested portion of the Option
on or before the earlier of (i) one year after your Termination of Service and
(ii) the Option Expiration Date.

            (c)   Death. If your employment or service relationship terminates
due to your death, the vested portion of the Option must be exercised on or
before the earlier of (i) one year after your Termination of Service and (ii)
the Option Expiration Date. If you die after your Termination of Service but
while the Option is still exercisable, the vested portion of the Option may be
exercised until the earlier of (x) one year after the date of death and (y) the
Option Expiration Date; and

            (d)   Cause. The vested portion of the Option will automatically
expire at the time the Company first notifies you of your Termination of Service
for Cause, unless the Plan Administrator determines otherwise. If your
employment or service relationship is suspended pending an investigation of
whether you will be terminated for Cause, all your rights under the Option
likewise will be suspended during the period of investigation. If any facts that
would constitute termination for Cause are discovered after your Termination of
Service, any Option you then hold may be immediately terminated by the Plan
Administrator.

    IT IS YOUR RESPONSIBILITY TO BE AWARE OF THE DATE THE OPTION TERMINATES.

      6.    LIMITED TRANSFERABILITY. During your lifetime only you can exercise
the Option. The Option is not transferable except by will or by the applicable
laws of descent and distribution, except that Nonqualified Stock Options may be
transferred to the extent permitted by the Plan Administrator. The Plan provides
for exercise of the Option by a beneficiary designated on a Company-approved
form or the personal representative of your estate.

      7.    WITHHOLDING TAXES. As a condition to the exercise of any portion of
an Option, you must make such arrangements as the Company may require for the
satisfaction of any federal, state, local or foreign withholding tax obligations
that may arise in connection with such exercise.

      8.    OPTION NOT AN EMPLOYMENT OR SERVICE CONTRACT. Nothing in the Plan or
any Award granted under the Plan will be deemed to constitute an employment
contract or confer or be deemed to confer any right for you to continue in the
employ of, or to continue any other relationship with, the Company or any
Related Company or limit in any way the right of the Company or any Related
Company to terminate your employment or other relationship at any time, with or
without Cause.

      9.    NO RIGHT TO DAMAGES. You will have no right to bring a claim or to
receive damages if you are required to exercise the vested portion of the Option
within three months (one year in the case of Disability or death) of the
Termination of Service or if any portion of the Option is cancelled or expires
unexercised. The loss of existing or

                                                                               3
<PAGE>
potential profit in Awards will not constitute an element of damages in the
event of your Termination of Service for any reason even if the termination is
in violation of an obligation of the Company or a Related Company to you.

      10.   BINDING EFFECT. This Agreement will inure to the benefit of the
successors and assigns of the Company and be binding upon you and your heirs,
executors, administrators, successors and assigns.

      [INCLUDE THESE SECTIONS FOR NON-US RESIDENTS ONLY: 11. LIMITATION ON
RIGHTS; NO RIGHT TO FUTURE GRANTS; EXTRAORDINARY ITEM OF COMPENSATION. By
entering into this Agreement and accepting the grant of the Option evidenced
hereby, you acknowledge: (a) that the Plan is discretionary in nature and may be
suspended or terminated by the Company at any time; (b) that the grant of the
Option is a one-time benefit which does not create any contractual or other
right to receive future grants of options, or benefits in lieu of options; (c)
that all determinations with respect to any such future grants, including, but
not limited to, the times when options will be granted, the number of shares
subject to each option, the option price, and the time or times when each option
will be exercisable, will be at the sole discretion of the Company; (d) that
your participation in the Plan is voluntary; (e) that the value of the Option is
an extraordinary item of compensation which is outside the scope of your
employment contract, if any; (f) that the Option is not part of normal or
expected compensation for purposes of calculating any severance, resignation,
redundancy, end of service payments, bonuses, long-service awards, pension or
retirement benefits or similar payments; (g) that the vesting of the Option
ceases upon your Termination of Service for any reason except as may otherwise
be explicitly provided in the Plan or this Agreement or otherwise permitted by
the Plan Administrator; (h) that the future value of the Shares underlying the
Option is unknown and cannot be predicted with certainty; and (i) that if the
Shares underlying the Option do not increase in value, the Option will have no
value.

      12.   EMPLOYEE DATA PRIVACY. By entering this Agreement, you (a) authorize
the Company and your employer, if different, and any agent of the Company
administering the Plan or providing Plan recordkeeping services, to disclose to
the Company or any of its affiliates any information and data the Company
requests in order to facilitate the grant of the Option and the administration
of the Plan; (b) waive any data privacy rights you may have with respect to such
information; and (c) authorize the Company and its agents to store and transmit
such information in electronic form.]
