               Dated as of April 7, 1997 (the "Effective Date")


      WHEREAS, Cardima, Inc., a Delaware corporation (the "Company") has entered
into a Master Lease Agreement dated as of January 23, 1996, Equipment Schedule
No. VL-2 dated as of April 7, 1997, and related Summary Equipment Schedules
(collectively, the "Leases") with Comdisco, Inc., a Delaware corporation (the
"Warrantholder"); and

      WHEREAS, the Company desires to grant to Warrantholder, in consideration
for such Leases, the right to purchase shares of its Series E Preferred Stock;

      NOW THEREFORE, in consideration of the Warrantholder executing and
delivering such Leases and in consideration of mutual covenants and agreements
contained herein, the Company and Warrantholder agree as follows:

1.    GRANT OF THE RIGHT TO PURCHASE PREFERRED STOCK
      ----------------------------------------------

The Company hereby grants to the Warrantholder, and the Warrantholder is
entitled, upon the terms and subject to the conditions hereinafter set forth, to
subscribe to and purchase, from the Company 13,937 fully paid and non-assessable
shares of Company's Series E Preferred Stock ("Preferred Stock") at a purchase
price of $5.74 per share (the "Exercise Price").  The number and purchase price
of such shares are subject to adjustment as provided in Section 8 hereof.

2.    TERM OF THE WARRANT AGREEMENT
      -----------------------------

Except as otherwise provided for herein, the term of this Warrant Agreement and
the right to purchase Preferred Stock as granted herein shall commence on the
Effective Date and shall be exercisable for a period of (i) ten (10) years or
(ii) five (5) years from the effective date of the Company's initial public
offering, whichever is longer.

3.    EXERCISE OF THE PURCHASE RIGHTS.
      -------------------------------

The purchase rights set forth in this Warrant Agreement are exercisable by the
Warrantholder, in whole or in part, at any time, or from time to time, prior to
the expiration of the term set forth in Section 2 above, by tendering to the
Company at its principal office a notice of exercise in the form attached hereto
as Exhibit I (the "Notice of Exercise") duly completed and executed.  Promptly
upon receipt of the Notice of Exercise and the payment of the purchase price in
accordance with the terms set forth below, and in no event later than twenty-one
(21) days thereafter, the Company shall issue to the Warrantholder a certificate
for the number of shares of Preferred Stock purchased and shall execute the
acknowledgment of exercise in the form attached hereto as Exhibit II (the
"Acknowledgment of Exercise") indicating the number shares which remain
subject to future purchases, if any.

The Exercise Price may be paid at the Warrantholder's election either (i) by
cash or check, or (ii) by surrender of Warrants ("Net Issuance") as determined
below.  If the Warrantholder elects the Net Issuance method, the Company will
issue Preferred Stock in accordance with the following formula:

                                      -1-
<PAGE>

          X = Y(A-B)
              ------
                A

Where:    X = the number of shares of Preferred Stock to be issued to the
                 Warrantholder.

          Y = the number of shares of Preferred Stock requested to be exercised
                 under this Warrant Agreement.

          A = the fair market value of one (1) share of Preferred Stock.

          B = the Exercise Price.

For purposes of the above calculation, current fair market value of Preferred
Stock shall mean with respect to each share of Preferred Stock:

     (a)  if the exercise is in connection with an initial public offering of
the Company's Common Stock, and if the Company's Registration Statement relating
to such public offering has been declared effective by the SEC, then the fair
market value per share shall be the product of (x) the initial "Price to Public"
specified in the final prospectus with respect to the offering and (y) the
number of shares of Common Stock into which each share of Preferred Stock is
convertible at the time of such exercise;

     (b)  if this Warrant is exercised after, and not in connection with, the
Company's initial public offering and:

          (i)  if traded on a securities exchange, the fair market value shall
     be deemed to be the product or (x) the average of the closing prices over a
     twenty-one (21) day period ending three days before the day the current
     fair market value of the securities is being determined and (y) the number
     of shares of Common Stock into which each share of Preferred Stock is
     convertible at the time of such exercise; or

          (ii) if actively traded over-the-counter, the fair market value shall
     be deemed to be the product of (x) the average of the closing bid and asked
     prices quoted on the Nasdaq system (or similar system) over the twenty-one
     (21) day period ending three days before the day the current fair market
     value of the securities is being determined and (y) the number of shares of
     Common Stock into which each share of Preferred Stock is convertible at the
     time of such exercise;

     (c)  if at any time the Common Stock is not listed on any securities
exchange or quoted in the Nasdaq System or the over-the-counter market, the
current fair market value of Preferred Stock shall be the product of (x) the
highest price per share which the Company could obtain from a willing buyer (not
a current employee or director) for shares of Common Stock sold by the Company,
from authorized but unissued shares, as determined in good faith by its Board of
Directors and (y) the number of shares of Common Stock into which each share of
Preferred Stock is convertible at the time of such exercise, unless the Company
shall become subject to a merger, acquisition or other consolidation pursuant to
which the Company is not the surviving party, in which case the fair market
value of Common Stock shall be deemed to be the value received by the holders of
the Company's Preferred Stock on a common equivalent basis pursuant to such
merger or acquisition.

Upon partial exercise by either cash or Net Issuance, the Company shall promptly
issue an amended Warrant Agreement representing the remaining number of shares
purchasable hereunder.  All other terms and conditions of such amended Warrant
Agreement shall be identical to those contained herein, including, but not
limited to the Effective Date hereof.

4.   RESERVATION OF SHARES.
     ---------------------

     (a)  Authorization and Reservation of Shares.  During the term of this
          ---------------------------------------
Warrant Agreement, the Company will at all times have authorized and reserved a
sufficient number of shares of its Preferred Stock to provide for the exercise
of the rights to purchase Preferred Stock as provided for herein.

     (b)  Registration or Listing.  If any shares of Preferred Stock required to
          -----------------------
be reserved hereunder require registration with or approval of any governmental
authority under any Federal or State law (other than any registration under the
1933 Act, as then in effect, or any similar Federal statute then enforced, or
any state securities law, required

                                      -2-
<PAGE>

by reason of any transfer involved in such conversion), or listing on any
domestic securities exchange, before such shares may be issued upon conversion,
the Company will, at its expense and as expeditiously as possible, use its best
efforts to cause such shares to be duly registered, listed or approved for
listing on such domestic securities exchange, as the case may be.

5.   NO FRACTIONAL SHARES OR SCRIP.
     -----------------------------

No fractional shares or scrip representing fractional shares shall be issued
upon the exercise of the Warrant, but in lieu of such fractional shares the
Company shall make a cash payment therefor upon the basis of the Exercise Price
then in effort.

6.   NO RIGHTS AS SHAREHOLDER.
     ------------------------

This Warrant Agreement does not entitle the Warrantholder to any voting rights
or other rights as a shareholder of the Company prior to the exercise of the
Warrant.

7.   WARRANTHOLDER REGISTRY.
     ----------------------

The Company shall maintain a registry showing the name and address of the
registered holder of this Warrant Agreement.

8.   ADJUSTMENT RIGHTS.
     -----------------

The purchase price per share and the number of shares of Preferred Stock
purchasable hereunder are subject to adjustment, as follows:

     (a) Merger and Sale of Assets. If at any time there shall be a capital
         -------------------------
reorganization of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation when the Company is not the surviving corporation, or the sale of
all or substantially all of the Company's properties and assets to any other
person (hereinafter referred to as a "Merger Event"), then, as a part of such
Merger Event, lawful provision shall be made so that the Warrantholder shall
thereafter be entitled to receive, upon exercise of the Warrant, the number of
shares of preferred stock or other securities of the successor corporation
resulting from such Merger Event, equivalent in value to that which would have
been issuable if Warrantholder had exercised this Warrant immediately prior to
the Merger Event. In any such case, appropriate adjustment (as determined in
good faith by the Company's Board of Directors) shall be made in the application
of the provisions of this Warrant Agreement with respect to the rights and
interest of the Warrantholder after the Merger Event to the end that the
provisions of this Warrant Agreement (including adjustments of the Exercise
Price and number of shares of Preferred Stock purchasable) shall be applicable
to the greatest extent possible.

     (b) Reclassification of Shares. If the Company at any time shall, by
         --------------------------
combination, reclassification, exchange or subdivision of securities or
otherwise, change any of the securities as to which purchase rights under this
Warrant Agreement exist into the same or a different number of securities of any
other class or classes, this Warrant Agreement shall thereafter represent the
right to acquire such number and kind of securities as would have been issuable
as the result of such change with respect to the securities which were subject
to the purchase rights under this Warrant Agreement immediately prior to such
combination, reclassification, exchange, subdivision or other change.

     (c) Subdivision or Combination of Shares. If the Company at any time shall
         ------------------------------------
combine or subdivide its Preferred Stock, the Exercise Price shall be
proportionately decreased in the case of a subdivision, or proportionately
increased in the case of a combination.

     (d) Stock Dividends. If the Company at any time shall pay a dividend
         ---------------
payable in, or make any other distribution (except any distribution specifically
provided for in the foregoing subsections (a) or (b)) of the Company's stock,
then the Exercise Price shall be adjusted, from and after the record date of
such dividend or distribution, to that price determined by multiplying the
Exercise Price in effect immediately prior to such record date by a fraction (i)
the numerator of which shall be the total number of all shares of the Company's
stock outstanding immediately prior to

                                      -3-
      
<PAGE>

such dividend or distribution, and (ii) the denominator of which shall be the
total number of all shares of the Company's stock outstanding immediately after
such dividend or distribution.  The Warrantholder shall thereafter be entitled
to purchase, at the Exercise Price resulting from such adjustment, the number of
shares of Preferred Stock (calculated to the nearest whole share) obtained by
multiplying the Exercise Price in effect immediately prior to such adjustment by
the number of shares of Preferred Stock issuable upon the exercise hereof
immediately prior to such adjustment and dividing the product thereof by the
Exercise Price resulting from such adjustment.

     (e)  Antidilution Rights.  Additional antidilution rights applicable to
          -------------------
the Preferred Stock purchasable hereunder are as set forth in the Company's
Certificate of Incorporation, as amended through the Effective Date, a true and
complete copy of which is attached hereto as Exhibit __ (the "Charter").  The
Company shall promptly provide the Warrantholder with any restatement,
amendment, modification or waiver of the Charter that affects the
Warrantholder's rights under the Charter.  The Company shall provide
Warrantholder with prior written notice of any dilutive issuance of its stock or
other equity security as provided in the Charter to occur after the Effective
Date of this Warrant, which notice shall include (a) the price at which such
stock or security is to be sold, (b) the number of shares to be issued, and (c)
such other information as necessary for Warrantholder to determine if a dilutive
event has occurred.

     (f)  Notice of Adjustments.  If: (i) the Company shall declare any dividend
          ---------------------
or distribution upon its stock, whether in cash, property, stock or other
securities; (ii) there shall be any Merger Event; (iv) there shall be an initial
public offering; or (iii) there shall be any voluntary or involuntary
dissolution, liquidation or winding up of the Company; then, in connection with
each such event, the Company shall send to the Warrantholder; (A) at least
twenty (20) days' prior written notice of the date on which the books of the
Company shall close or a record shall be taken for such dividend, distribution
(specifying the date on which the holders of Preferred Stock shall be entitled
thereto) or for determining rights to vote in respect of such Merger Event,
dissolution, liquidation or winding up;(B) in the case of any such Merger Event,
dissolution, liquidation or winding up, at least twenty (20) days' prior written
notice of the date when the same shall take place (and specifying the date on
which the holders of Preferred Stock shall be entitled to exchange their
Preferred Stock for securities or other property deliverable upon such Merger
Event, dissolution, liquidation or winding up); and (C) in the case of a public
offering, the Company shall give the Warrantholder at least twenty (20) days
written notice prior to the effective date hereof.

Each such written notice shall set forth, in reasonable detail, (i) the event
requiring the adjustment, (ii) the amount of the adjustment, (iii) the method by
which such adjustment was calculated, (iv) the Exercise Price, and (v) the
number of shares subject to purchase hereunder after giving effect to such
adjustment, and shall be given by first class mail, postage prepaid, addressed
to the Warrantholder, at the address as shown on the books of the Company.

     (g)  Timely Notice.  Failure to timely provide such notice required by
          -------------
subsection (g) above shall entitle Warrantholder to retain the benefit of the
applicable notice period notwithstanding anything to the contrary contained in
any insufficient notice received by Warrantholder.  The notice period shall
begin on the date such notice is effectively given under Section 12(e) of this
Warrant Agreement.

10.  REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER.
     --------------------------------------------------

                                      -5-
<PAGE>

This Warrant Agreement has been entered into by the Company in reliance upon the
following representations and covenants of the Warrantholder:

     (a)  Investment Purpose.  The right to acquire Preferred Stock or the
          ------------------
Preferred Stock issuable upon exercise of the Warrantholder's rights contained
herein will be acquired for investment and not with a view to the sale or
distribution of any part thereof, and the Warrantholder has no present
intention of selling or engaging in any public distribution of the same except
pursuant to a registration or exemption under the 1933 Act.

     (b)  Private Issue.  The Warrantholder understands (i) that the Preferred
          -------------
Stock issuable upon exercise of this Warrant is not registered under the 1933
Act or qualified under applicable state securities laws on the ground that the
issuance contemplated by this Warrant Agreement will be exempt from the
registration and qualifications requirements thereof, and (ii) that the
Company's reliance on such exemption is predicated on the representations set
forth in this Section 10.

     (c)  Disposition of Warrantholder's Rights.  In no event will the
          -------------------------------------
Warrantholder make a disposition of any of its rights to acquire Preferred Stock
or Preferred Stock issuable upon exercise of such rights unless and until (i) it
shall have notified the Company of the proposed disposition, and (ii) if
requested by the Company, it shall have furnished the Company with an opinion of
counsel (which counsel may either be inside or outside counsel to the
Warrantholder) satisfactory to the Company and its counsel to the effect that
(A) appropriate action necessary for compliance with the 1933 Act has been
taken, or (B) an exemption from the registration requirements of the 1933 Act is
available. Notwithstanding the foregoing, the restrictions imposed upon the
transferability of any of its rights to acquire Preferred Stock or Preferred
Stock issuable on the exercise of such rights do not apply to transfers from the
beneficial owner of any of the aforementioned securities to its nominee or from
such nominee to its beneficial owner, and shall terminate as to any particular
share of Preferred Stock when (1) such security shall have been effectively
registered under the 1933 Act and sold by the holder thereof in accordance with
such registration or (2) such security shall have been sold without registration
in compliance with Rule 144 under the 1933 Act, or (3) a letter shall have been
issued to the Warrantholder at its request by the staff of the Securities and
Exchange Commission or a ruling shall have been issued to the Warrantholder at
its request by such Commission stating that no action shall be recommended by
such staff or taken by such Commission, as the case may be, if such security is
transferred without registration under the 1933 Act in accordance with the
conditions set forth in such letter or ruling and such letter or ruling
specifies that no subsequent restrictions on transfer are required. Whenever the
restrictions imposed hereunder shall terminate, as hereinabove provided, the
Warrantholder or holder of a share of Preferred Stock then outstanding as to
which such restrictions have terminated shall be entitled to receive from the
Company, without expense to such holder, one or more new certificates for the
Warrant or for such shares of Preferred Stock not bearing any restrictive
legend.

     (d)  Financial Risk.  The Warrantholder has such knowledge and experience
          --------------
is financial and business matters as to be capable of evaluating the merits and
risks of its investment, and has the ability to bear the economic risks of its
investment.

     (e)  Risk of No Registration.  The Warrantholder understands that if the
          -----------------------
Company does not register with the Securities and Exchange Commission pursuant
to Section 12 of the 1933 Act, or file reports pursuant to Section 15(d), of the
Securities Exchange Act of 1934 (the "1934 Act"), or if a registration statement
covering the securities under the 1933 Act is not in effect when it desires to
sell (i) the rights to purchase Preferred Stock pursuant to this Warrant
Agreement, or (ii) the Preferred Stock issuable upon exercise of the right to
purchase, it may be required to hold such securities for an indefinite period.
The Warrantholder also understands that any sale of its rights of the
Warrantholder to purchase Preferred Stock or Preferred Stock which might be made
by it in reliance upon Rule 144 under the 1933 Act may be made only in
accordance with the terms and conditions of that Rule.

     (f)  Accredited Investor.  Warrantholder is an "accredited investor" within
          -------------------
the meaning of the Securities and Exchange Rule 501 of Regulation D, as
presently in effect.

11.  TRANSFERS.  Subject to the terms and conditions contained in Section 10
     ---------
hereof, this Warrant Agreement and all rights hereunder are transferable in
whole or part by the Warrantholder and any successor transferee, provided,
however, in no event shall the number of transfers of the rights and interests
in all of the Warrants exceed three (3) transfers. The transfer shall be
recorded on the books of the Company upon receipt by the Company of a notice of

                                      -6-

damages will not be readily ascertainable.  The Company expressly agrees that
it shall not oppose an application by the Warrantholder or any other person
entitled to the benefit of this Agreement requiring specific performance of any
or all provisions hereof or enjoining the Company from continuing to commit any
such breach of this Agreement.

     (g)  No Impairment of Rights.  The Company will not, by amendment of its
          -----------------------
Charter or through any other means, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
actions as may be necessary or appropriate in order to protect the rights of the
Warrantholder against impairment.

     (h)  Survival.  The representations, warranties, covenants and conditions
          --------
of the respective parties contained herein or made pursuant to this Warrant
Agreement shall survive the execution and delivery of this Warrant Agreement.

     (i)  Severability.  In the event any one or more of the provisions of this
          ------------
Warrant Agreement shall for any reason be held invalid, illegal or
unenforceable, the remaining provisions of this Warrant Agreement shall be
unimpaired, and the invalid, illegal or unenforceable provision shall be
replaced by a mutually acceptable valid, legal and enforceable provision, which
comes closest to the intention of the parties underlying the invalid, illegal or
unenforceable provision.

     (j)  Amendments.  Any provision of this Warrant Agreement may be amended by
          ----------
a written instrument signed by the Company and the Warrantholder.

     (k)  Additional Documents.  If the purchase price for the Leases
          --------------------
referenced in the preamble of this Warrant Agreement exceeds $1,600,000,
the Company will also provide Warrantholder with an opinion from the Company's

                                      -7-

counsel with respect to those same representations, warranties and covenants. 
The Company shall also supply such other documents as the Warrantholder may from
time to time reasonably request.

IN WITNESS WHEREOF, the parties hereto have caused this Warrant Agreement to be
executed by its officers thereunto duly authorized as of the Effective Date.
