Issuer shall determine the average closing price of the Common Stock for the
month of November 1999 (the "Average Closing Price"). If the Average Closing

               Company and its officers and directors regarding matters relevant
               to the Company and an investment therein (e.g., as represented by
               the Subscription); and

          (ii) further, had the opportunity to obtain any and all publicly
               available information which the Purchaser deems necessary to
               evaluate the Company and the investment represented by the
               Subscription as well as to verify the accuracy of information
               otherwise provided to the Purchaser.

          c. The Purchaser is experienced in making investments in unregistered
and restricted securities. The Purchaser has such knowledge and experience in
financial and business matters that the Purchaser is capable of evaluating the
merits and risks of the investment in the Company represented by the
Subscription and, by reason of the Purchaser's financial and business
experience, the Purchaser has the capacity to protect the Purchaser's interest
in connection with the Subscription.

          d. The Purchaser has either (i) a preexisting personal or business
relationship with the Company or one or more of its officers, directors or
control persons or (ii) by reason of the Purchaser's business or financial
experience, the Purchaser is capable of evaluating the risks and merits of the
investment represented by the Subscription and of protecting the Purchaser's own
interests in connection with such investment.

          e. The Purchaser is an "accredited investor" as that term is defined
in Rule 501 promulgated under the Securities Act of 1933, as amended (the
"Act").

          f. The Shares are being acquired by the Purchaser (i) solely for
investment purposes, (ii) for the Purchaser's own account only and (iii) not for
sale, transfer or with a view to any distribution of all or any part of such
Shares. No other person will have any direct or indirect beneficial interest in
the Shares.


3.       UNDERSTANDINGS AND ACKNOWLEDGEMENTS

          a. The Purchaser acknowledges that the Shares have not been registered
under the Act or qualified under the California Corporate Securities Law of
1968, as amended, or any other applicable blue sky laws in reliance, in part, on
the representations and warranties herein.


<PAGE>

          b. The Purchaser understands that (i) the Shares are restricted
securities under the federal securities laws (e.g., the Act) insofar as the
Shares will be acquired from the Company in a transaction not involving a public
offering, (ii) under such laws and applicable regulations, the Shares may be
resold without registration under the Act only in certain limited circumstances
and (iii) in the absence of registration under the Act, the Shares must be held
indefinitely. The Purchaser understands the resale limitations imposed by the
Act and is familiar with Rule 144 under the Act, as presently in effect, and the
conditions which must be met in order for Rule 144 to be available with respect
to the resale of restricted securities.


          c. The Purchaser understands that any certificates evidencing the
Shares may bear one or all of the following legends:

          (i)  THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
               ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE,
               TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A
               REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES
               UNDER SUCH ACT OR AN OPINION OF COUNSEL OR OTHER EVIDENCE
               SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT
               REQUIRED OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SUCH ACT.

          (ii) Any legend required by applicable state securities laws.


4.       COVENANTS

          a. Without in any way limiting the representations set forth above,
the Purchaser further agrees not to make any disposition of all or any portion
of the Shares purchased hereunder unless and until:

          (i)  There is then in effect a registration statement under the Act
               covering such proposed disposition and such disposition is made
               in accordance with such registration statement and any applicable
               requirements of state securities laws; or

          (ii) The Purchaser shall have (1) notified the Company of the proposed
               disposition, (2) furnished the Company with a detailed statement
               of the circumstances surrounding the proposed disposition and (3)
               furnished the Company with a written opinion of counsel,
               reasonably satisfactory to the Company, that such disposition
               will not require registration of any securities under the Act or
               the consent of (or a permit from) any authority under any
               applicable state securities laws.
<PAGE>

The Purchaser understands that the Company will not require opinions of counsel
for transactions made pursuant to Rule 144 under the Act provided that the
Company receives all certificates and other information it may reasonably
request to permit it to determine that the subject disposition is, in fact,
exempt from the registration requirements of the Act pursuant to Rule 144.

          b. In the case of any disposition of any Shares pursuant to Rule 144
under the Act, then in addition to the matters set forth in paragraph 4(a)(ii)
above, the Purchaser shall promptly forward to the Company a copy of any Form
144 filed with the Securities and Exchange Commission (the "SEC") with respect
to such disposition and a letter from the executing broker satisfactory to the
Company evidencing compliance with Rule 144. If Rule 144 is amended or if the
SEC's interpretations thereof in effect at the time of any such disposition by
the Purchaser have changed from the SEC's present interpretations thereof, the
Purchaser shall provide the Company with such additional documents as the
Company may reasonably require.


5.       PRICE RESET

          a. On November 30, 1999, the Company shall determine the average
closing price for the shares of Common Stock of the Company for the month of
November 1999 (the "Average Closing Price"). If the Average Closing Price is
less than $1.00, the Company shall promptly issue to Purchaser hereunder without
payment of additional consideration therefor a number of additional shares of
Common Stock of the Company (the "Reset Shares") equal to the Aggregate Purchase
Price as shown on the Signature Page divided by the Average Closing Price less
the Shares Purchased as shown on the Signature Page. By way of example, if the
Average Closing Price is $0.80 and the Purchaser has purchased 100,000 Shares
for an Aggregate Purchase Price of $100,000, then the Company shall issue to
Purchaser an additional 25,000 Reset Shares calculated as follows: $100,000
divided by $0.80 equals 125,000 less 100,000 equals 25,000 Reset Share.

          b. The additional shares of Common Stock of the Company, if any,
issued hereunder shall be subject to the restrictions, limitations and
conditions imposed upon the Shares issued upon the initial subscription under
this Agreement.


6.       REGISTRATION RIGHTS

          a. On or before November 30, 1999, the Company at its expense shall
file with the SEC a Registration Statement on Form S-3 (the "Registration
Statement") under the Act registering for resale by Purchaser, and all other
Purchasers under similar Agreements, the Shares and the Reset Shares, if any.
The Company shall use its reasonable best efforts to cause the Registration
Statement to be declared effective and to remain in effect until May 28, 2001 or
until all Reset Shares included within the Registration Statement have been sold
by the Purchaser and all other Purchasers under similar Agreements or may be
sold pursuant to Rule 144, whichever shall first occur.


<PAGE>

          b. In connection with the filing of the Registration Statement, the
Company shall indemnify the Purchaser against any liability under the Act for
the information concerning the Company contained in the Registration Statement
or incorporated by reference therein and shall at its expense make available to
Purchaser such number of copies of the prospectus constituting a part of the
Registration Statement as is reasonably necessary to allow Purchaser to resell
the Reset Shares.


7.       MISCELLANEOUS

          a. This Agreement shall be governed by and construed in accordance
with the internal laws of the State of California (without regard to the
conflicts of law principles thereof).

          b. This Agreement embodies the entire understanding between the
parties and supersedes any prior understandings, agreements and arrangements
between the parties respecting the subject matter hereof. There are no
representations, warranties, agreements, arrangements or understandings, oral or
written, between the parties hereto relating to the subject matter of this
Agreement which are not fully expressed herein.

          c. This Agreement may be executed in counterparts, each of which shall
be deemed an original, but all of which together shall constitute one and the
same instrument. The execution and delivery of signatures for this Agreement may
occur via telecopy, and such telecopied Signature Pages shall have the force and
effect of original signature pages.

          IN WITNESS WHEREOF, the Purchaser has executed this Agreement as of
May ___, 1999.

Dear Mr. Paulson:

          This letter confirms the intent of accounts managed by Domain
Associates ("Domain") to purchase 3,000,000 shares of CardioDynamics, Inc. (the
"Company") common shares presently owned by Allen E. Paulson, Trustee for the
Allen E. Paulson Living Trust ("Paulson") at a price of $1.20 per share, for a
total consideration of $3,600,000.00. We understand that the shares being
purchased carry a legend which will restrict subsequent sale and redistribution
by our managed accounts.

          Countersignature of this letter by you (or any other authorized
representative of Paulson) will confirm the intent of Paulson to effect the sale
of CardioDynamics shares as outlined above, and will further confirm that no
prior agreements exist which would preclude your ability to sell and transfer
these shares to the Domain accounts in an orderly fashion.

          Upon receipt of such countersigned letter, Domain will arrange to wire
transfer the agreed upon sum of $3,600,000.00 to the following account:

          Assuming that we receive a fax copy of this countersigned letter on
Friday, June 4, 1999, we would expect to effect the wire transfer on Monday,
June 7, 1999.

          Paulson will use its best efforts to effect timely delivery of the
share certificates to the Company (or its transfer agent) so that new share
certificates may be reissued to the following Domain accounts:

ACCOUNT NAME                        NUMBER OF SHARES

Domain Partners IV, L.P.            2,929,793

DP IV Associates, L.P.                 70,207

          By copy of this letter, Domain and Paulson are notifying the Company
about this transaction. The Company has previously agreed to cooperate in the
expeditious transfer of shares as outlined above.
