(1) Potential realizable value is based on the assumption that the Common Stock
    of the Company appreciates at the annual rate shown (compounded annually)
    from the date of grant until the expiration of the ten year option term.
    These numbers are calculated based on the requirements promulgated by the
    Securities and Exchange Commission and do not reflect the Company's estimate
    of future price growth.

(2) Options become exercisable to 1/48 of the option shares at the end of each
    month following the date of grant, with full vesting occurring on the fourth
    anniversary of the date of grant, other than Mr. Prescott's grant which
    becomes exercisable as to 1/4 of the shares on the first anniversary of the
    date of grant and the remainder of which vest monthly as to 1/48 thereafter.

(3) Options were granted at an exercise price equal to the fair market value of
    the Company's Common Stock on the date of grant.

(4) Exercise price may be paid in cash, check, promissory note, by delivery of
    already-owned shares of the Company's Common Stock subject to certain
    conditions, delivery of a properly executed exercise notice together with
    irrevocable instructions to a broker to deliver promptly to the Company
    amount of sale or loan proceeds required to pay the exercise price, a
    reduction in the amount of any Company liability to an optionee, or any
    combination of the foregoing methods of payment or such other consideration
    or method of payment to the extent permitted under applicable law.

(5) In connection with separation agreements entered into by Dr. Echt and Dr.
    Hunt with the Company, unvested options to purchase common stock of the
    Company expired as of the day they resigned from the Company. The remaining
    vested shares were exercisable for up to 30 days after their resignation.
    Both Dr. Echt and Dr. Hunt exercised all of the options they were entitled
    to exercise prior to the expiration dates.

EMPLOYMENT CONTRACTS AND CHANGE-IN-CONTROL ARRANGEMENTS

     Ms. Miller, Messrs. Bullington, Weigle, and Riley have entered into
employment agreements with the Company pursuant to which the Company may
terminate their employment at any time with or without cause; provided, however,
that if employment is terminated with cause, the Company will pay the employee a
severance payment in an amount equal to one month of the employee's then-current
monthly base salary and if the employee's employment is terminated without
cause, the Company will pay the employee a severance payment of an amount equal
to twelve months of the employee's then-current monthly base salary. The
agreements also provide that all outstanding stock options held by the employees
become immediately exercisable in the event that the employee's employment is
terminated without cause or is constructively terminated in connection with a
merger, reorganization or sale of substantially all of the assets of the Company
in which stockholders of the Company immediately prior to the transaction
possess less than fifty percent (50%) of the voting power of the surviving
entity (or its parent) immediately after the transaction.

     On July 23, 1999, the Company and Mr. Prescott entered into an employment
agreement that, among other things, provided Mr. Prescott with an annual base
salary of $265,000 and options to purchase (i) 187,306 shares of the Company's
common stock at an exercise price of $4.50 per share, and (ii) 100,000 shares of
the Company's common stock at an exercise price of $4.63 per share. One-fourth
of Mr. Prescott's options will vest on each anniversary of his employment over
the next four years. In the event Mr. Prescott is terminated without justifiable
cause during the first year of his employment, Mr. Prescott will be entitled to
acceleration of vesting as to 1/48 of such options for each full month of
employment. Mr. Prescott is also entitled to immediate vesting of 100% of his
shares if a merger or other sale of the Company results in a change in control
of its voting stock and Mr. Prescott is involuntarily terminated.

     In addition to options to purchase the Company's common stock, Mr. Prescott
is entitled to the following:

     - a $250,000 loan from the Company at a 7% interest rate to purchase shares
       of the Company's Series B Convertible Preferred Stock (the "Series B
       Preferred"). This loan is payable in 12 quarterly installments commencing
       on the third anniversary of the loan;

     - relocation expenses;

     - a one-time bonus of $75,000 paid on June 25, 1999 (subsequently this
       bonus was adjusted by mutual agreement between Mr. Prescott and the
       Company to $46,759);

                                        6
<PAGE>   7

     - severance of 12 months of his then current monthly salary in the event
       Mr. Prescott is terminated without justifiable cause; and

     - a bonus of up to 25% of his then current salary upon the attainment of
       goals set by the board of directors for each fiscal year during which Mr.
       Prescott remains Chief Executive Officer.

     Dr. Echt and Dr. Hunt entered into separation agreements with the Company,
pursuant to which Dr. Echt and Dr. Hunt resigned effective February 18, 2000 and
June 30, 2000, respectively. Pursuant to their agreements with the Company, Dr.
Echt received a lump sum severance payment equal to 5 months of her then current
monthly base salary and Dr. Hunt received a lump sum severance payment equal to
6 months of his then current monthly base salary. In addition to her lump sum
severance, Dr. Echt also received her then current monthly pay for the period
from February 18, 2000 through June 18, 2000 as if she were still employed. Dr.
Hunt also received forgiveness on the principal and interest for a $60,000 loan
made to him by the Company in addition to his lump sum severance.

DIRECTOR COMPENSATION

     In fiscal 2000, nonemployee directors who were neither affiliated with nor
nominated by a stockholder that owned one percent or more of the outstanding
capital stock of Cardiac Pathways (the "Outside Directors") were entitled to
receive a fee of $1,500 for attendance at each general Board of Directors
meeting, $500 if present at such meeting by telephone, a fee of $150 for
attendance at each committee meeting for services provided in that capacity and
were reimbursed for out of pocket expenses incurred in connection with their
attendance at Board of Director or committee meetings. There are currently no
Outside Directors.

     Under Cardiac Pathways' 1996 Director Option Plan, Outside Directors may
receive stock option grants pursuant to an automatic nondiscretionary grant
mechanism. The exercise price of the options is set at 100% of the fair market
value of Cardiac Pathways' common stock on the grant date. The Director Option
Plan provides for an initial option grant to purchase 2,600 shares of common
stock to each new Outside Director of the Company. In addition, each Outside
Director is automatically granted an option to purchase 140 shares of common
stock at the next meeting of the Board of Directors following each Annual
Meeting of Stockholders, if on such date, such director has served on the Board
of Directors for at least the preceding six months. The terms of each of these
grants are ten years, provided that such options shall terminate three months
following the termination of the optionee as a director (or twelve months if the
termination is due to death or disability). The initial grant vests at a rate of
25% of the shares subject to such option on the first anniversary of the date of
grant and at a rate of 1/48 of such shares per month thereafter. The annual
grants vest at a rate of 1/8 of the shares subject to such option six months
after the date of grant and at a rate of 1/48 of such shares per month
thereafter.

     On July 25, 2000, Dr. Kuo received an option to purchase 20,000 shares of
the Company's common stock under the Company's 1991 Stock Option Plan at an
exercise price of $4.88 per share. This one-time award of stock to Dr. Kuo was
granted to him in consideration of his ongoing and future activities related to
the Company's business operations and future strategic direction.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The Compensation Committee consists of directors Kuo and Brooks. Dr. Kuo
and Mr. Brooks are both representatives of the Series B Preferred stockholders.
Mr. Brooks is a general partner and managing director of BA Venture Partners, an
entity which owns 10,000 shares of the Company's Series B Preferred which is
currently convertible into 2,000,000 common shares. BA Venture Partners bought
these shares of Series B Preferred pursuant to a financing which closed in July
1999. For further discussion of this financing please see the section entitled
"Certain Transactions -- Series B Financing."

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

  Series B Financing

     In July 1999, the Company's stockholders authorized and the Company
completed a $32 million offering of Series B Preferred at $1,000 per share to a
group of accredited investors. In connection with this Series B Preferred
financing, the Company raised $31.5 million, net of issuance costs. In June
2000, one of the holders of Series B Preferred converted 5,000 shares of Series
B Preferred into 1,000,000 shares of common stock. The 1,000,000 shares of
common stock were issued as unregistered common stock to an affiliate of the
Company subject to regulating restrictions and holding period requirements. The
remaining 27,750 shares of Series B Preferred are convertible at the option of
the holders into 5.45 million shares of common stock.

     The financing was severely dilutive to the Company's then existing
stockholders. The following table summarizes the dilutive effect, for percentage
ownership purposes, of the financing on the stockholders based on outstanding
share information as of June 30, 2000:

</TABLE>

     This table does not give effect to the issuance of warrants to purchase 300
shares of Series B Preferred (convertible into 60,000 shares of common stock) in
connection with interim funding provided to the Company.

     The holders of the Series B Preferred are entitled to significant rights,
preferences and privileges as a result of their investment.

     The two largest holders of Series B Preferred control three of five seats
(60%) on the Board. The members of the Board include Thomas M. Prescott,
President and Chief Executive Officer of the Company, Mark J. Brooks, Anchie Y.
Kuo, M.D. and M. Fazle Husain, nominees of the holders of Series B Preferred

                                        9
<PAGE>   10

and William N. Starling, a former director, chief executive officer and
president of the Company. The consent of the directors nominated by the holders
of Series B Preferred will be required to increase the number of directors above
the number currently in office.

     Each share of Series B Preferred is convertible into 200 shares of common
stock. The conversion ratio of the Series B Preferred is subject to adjustment
for price based antidilution.

     The holders of Series B Preferred are entitled to a cumulative dividend
when, as and if declared by the Board at a rate per share equal to 11% per annum
of the initial purchase price of the Series B Preferred. The Series B Preferred
has a liquidation preference equal to the initial purchase price plus any
accrued dividends upon the occurrence of a liquidation, a merger or the sale of
all or substantially all of the Company's stock or assets. As a result of the
liquidation preference, in the event of a liquidation, merger or the sale of
substantially all of the Company's stock or assets, the holders of the Series B
Preferred will receive their original purchase price plus any accrued dividends
prior to any distribution to the holders of common stock.

     The Series B Preferred is redeemable after May 31, 2004 at the request of a
majority of the holders, subject to the approval of the Company. If a redemption
request is received but not approved by the Company, the cumulative dividend
rate payable on the Series B Preferred will increase by six percentage points
for each year a redemption does not occur.

     The holders of the Series B Preferred vote on all matters presented to
stockholders on an as-converted to common stock basis. In addition, the
affirmative vote of holders of a majority of the Series B Preferred, voting as a
separate class, will be required to:

          1. Amend or repeal any provision, or add any provision to the
     certificate of incorporation or bylaws which changes the rights of the
     Series B Preferred;

          2. Increase or decrease (other than by redemption or conversion) the
     total number of authorized shares of preferred stock or common stock;

          3. Authorize or issue, or obligate itself to issue, any other security
     convertible into or exercisable for any security having a preference over,
     or being on a parity with, the Series B Preferred with respect to voting,
     dividends, redemption or upon liquidation;

          4. Issue any shares of common stock, other than

          (a) shares of common stock issuable or issued to employees,
     consultants or directors of the Company directly or pursuant to a stock
     option plan or restricted stock plan approved by the board of directors,
     including the representatives of the Series B Preferred;

          (b) shares of common stock issuable or issued upon conversion of the
     Series A Participating Preferred Stock or the Series B Preferred or as
     dividends or distributions on the Series A Participating Preferred Stock or
     the Series B Preferred;

          (c) shares of common stock issuable or issued upon exercise of
     warrants issued to banks, equipment lessors or other vendors, where such
     common stock or warrants were approved by the board of directors, including
     the representatives of the Series B Preferred; or

          (d) shares of common stock issuable or issued as consideration for
     business combinations or corporate partnering agreements approved by the
     board of directors, including the representatives of the Series B
     Preferred.

          5. Declare or pay any dividends on its common stock or redeem,
     purchase or otherwise acquire (or pay into or set aside for a sinking fund
     for such purpose) any share or shares of common stock, provided, however,
     that this restriction shall not apply to the repurchase of shares of common
     stock from employees, officers, directors, consultants or other persons
     performing services for Cardiac Pathways or any subsidiary pursuant to
     agreements under which Cardiac Pathways has the option to repurchase such
     shares at cost or at cost upon the occurrence of certain events, such as
     the termination of employment;

                                       10
<PAGE>   11

          6. Sell, convey or otherwise dispose of all or substantially all of
     its property or business or merge into or consolidate with any other
     corporation (other than a wholly-owned subsidiary corporation) or effect
     any transaction or series of related transactions in which more than fifty
     percent (50%) of the voting power of this corporation is disposed of;

          7. Repurchase any series of preferred stock; or

          8. Increase or decrease the size of the board of directors.

     The holders of the Series B Preferred have a right of first offer with
respect to future financings by the Company.

     The holders of 45% of the then outstanding Series B Preferred will have the
right to request that the Company register the shares of common stock into which
the Series B Preferred are convertible after May 21, 2000. In addition, if the
Company otherwise registers shares of its common stock, the holders of the
Series B Preferred will be entitled to participate in the registration.

     The foregoing transaction did not involve any underwriters, underwriting
discounts or commissions or any public offering, and we believe that each
transaction was exempt from the registration requirements of the Securities Act
by virtue of Section 4(2) thereof or Regulation D promulgated thereunder. The
recipients in such transactions represented their intention to acquire the
securities for investment only and not with a view to or for resale in
connection with any distribution thereof, and appropriate legends were affixed
to the share certificates and instruments issued in such transactions. All
recipients had adequate access, through their relationships with us, to
information about us.

  Other Transactions with Directors, Executive Officers and Others

     In May 1999, William N. Starling resigned as President and Chief Executive
Officer of the Company. Mr. Starling remained a member of the Board of
Directors. The Company, the holders of the Series B Preferred and Mr. Starling
agreed that for as long as Mr. Starling continues as a member of the Board, the
options to purchase common stock held by Mr. Starling will continue to vest. As
of the date he resigned as President and Chief Executive Officer, Mr. Starling
held 9,458 shares subject to unvested options to purchase common stock. On
January 1, 2000, Mr. Starling entered into a consulting agreement with the
Company to provide the Company with business development and strategy consulting
services on a directed basis. Mr. Starling was paid a total of $144,865 through
the period ending June 30, 2000, the expiration date of the agreement.

  Arrow International, Inc. Relationship

     In June 1995 and December 1995, an aggregate of 606,667 shares of Series F
Preferred Stock was sold to Arrow International, Inc. ("Arrow") at a price of
$15.00 per share for an aggregate purchase price of approximately $9.1 million.
In the transaction Arrow also acquired warrants to purchase 7,667 shares of
Series F Preferred Stock at an exercise price of $13.125, which expire on the
earlier of June 2000 or the closing date of a transaction involving a change of
control. Each share of Series F Preferred Stock was converted automatically into
one share of Common Stock upon the closing of the initial public offering of the

     We believe that all of the transactions set forth above were made on terms
no less favorable to the Cardiac Pathways than could have been obtained from
unaffiliated third parties. All future transactions, including loans, between
Cardiac Pathways and its officers, directors, principal stockholders and their
affiliates will be approved by a majority of the Board of Directors, including a
majority of the independent and disinterested outside directors, and will
continue to be on terms no less favorable to Cardiac Pathways than could be
obtained from unaffiliated third parties.
