3.   NET LOSS PER SHARE

In 1997, the Financial Accounting Standards Board issued Statement No. 128,
"Earnings Per Share," ("SFAS 128").  SFAS 128 replaced the calculation of
primary and fully diluted earnings per share with basic and diluted earnings per
share.  Unlike primary earnings per share, basic earnings per share excludes any
dilutive effect of options, warrants and convertible securities.  Diluted
earnings per share is very similar to the previously reported fully diluted
earnings per share.  All earnings per share amounts for all periods have been
restated to conform to the SFAS 128 requirements.  Effective February 3, 1998,
Staff Accounting Bulletin No. 98 ("SAB 98") was issued and amends the existing
SEC staff guidance primarily to give effect to SFAS 128.  Topic 4.D of SAB 98
essentially eliminates the cheap stock (convertible preferred stock, redeemable
convertible preferred stock, common stock and common equivalent shares issued by
the Company at prices below the initial public offering price during the twelve-
month period prior to the offering) calculation from an initial public offering.

The Company has excluded all convertible debt, convertible preferred stock,
warrants and employee stock options from the computation of basic and diluted
earnings per share because all such securities are anti-dilutive for all periods
presented.

The following table sets forth the computation of basic and diluted earnings per
share (in thousands except for per share data):

OVERVIEW

The Company

Since its incorporation in November 1992, Cardima has been engaged in the
design, research, development, manufacturing and testing of microcatheter
systems for the mapping (diagnosis) and ablation (treatment) of cardiac
arrhythmias.  Cardima has generated revenues of approximately $3.4 million from
inception to June 30, 1998, which until January 1997 were primarily in Europe
and Japan, from sales of the Cardima Pathfinder and Tracer microcatheter systems
for diagnosing Ventricular Tachycardia (VT) and the Revelation microcatheter
system for diagnosing Atrial Fibrillation (AF), as well as ancillary products
such as the Venaport guiding catheters.  In January 1997, the Company received a
510(k) clearance in the United States and began to market and sell the Cardima
Pathfinder system for diagnosing VT.  As a result, the Company has derived a
majority of its revenues in 1997 and 1998 in the United States from sales of the
Cardima Pathfinder for diagnosis of VT.  In November 1997, the Company received
a 510(k) clearance in the United States and began to market and sell the
Revelation microcatheter for diagnosing AF.  To date, the Company's
international sales have been made primarily through distributors who sell the
Company's products to physicians and hospitals.

The Company has obtained the right to affix the CE mark to its Cardima
Pathfinder, Tracer and Cardima Revelation microcatheter systems, permitting the
Company to market these products in the member countries of the European Union
("EU").  The Company received 510(k) clearances for the Revelation microcatheter
for mapping of AF in November 1997,  for the Vueport balloon guiding catheter in
July 1998, and the Cardima Pathfinder Mini microcatheter for mapping VT in July
1998.  The Company is seeking 510(k) clearance for its Tracer mapping catheter
and its Naviport deflectable tip guiding catheter.  The Company will be required
to conduct clinical trials, demonstrate safety and effectiveness and obtain PMA
approval from the FDA in order to sell any of the Company's products designed
for treatment of AF or VT in the United States.  Specifically, PMA approval will
be required prior to the introduction in the United States of the Revelation Tx
microcatheter system for treatment of AF or Therastream microcatheter system for
treatment of VT.

The Company has a limited history of operations and has experienced significant
operating losses since inception.  The Company expects that its operating losses
will continue for the foreseeable future as the 

                                       9

Company continues to invest substantial resources in product development,
preclinical and clinical trials, obtaining regulatory approval, sales and
marketing and manufacturing.

RESULTS OF OPERATIONS - THREE AND SIX MONTHS ENDED 1998 AND 1997

Net Sales

Net sales for the quarter ended June 30, 1998 increased 96% to $625,000 from
$319,000 in the same period in 1997.  Net sales for the six month period ended
June 30, 1998 increased 110% to $1,126,000 from $536,000 in the same period in
1997.  Each of these increases is primarily due to U.S. sales of the Cardima
Pathfinder and Revelation lines of microcatheters for diagnosis of VT and AF,
respectively, following FDA clearance in January 1997 and November 1997,
respectively.  U.S. sales for the quarter ended June 30, 1998 increased 119% to
$451,000 from $206,000 in the same period in 1997.  U.S. sales for the six month
period ended June 30, 1998 increased 155% to $829,000 from $325,000 in the same
period in 1997.

Cost of Goods Sold

Cost of goods sold primarily includes raw materials costs, catheter fabrication
costs, system assembly, test costs and manufacturing overhead.  Cost of goods
sold for the quarter ended June 30, 1998 increased 30% to $595,000 from $457,000
in the same period in 1997.  Cost of goods sold for the six month period ended
June 30, 1998 increased 62% to $1,343,000 from $831,000 in the same period in
1997.  The increase is due primarily to the increase in sales volume and
associated manufacturing staff additions.

Research and Development Expenses

Research and development expenses for the quarter ended June 30, 1998 increased
80% to $1,908,000 from $1,059,000 in the same period in 1997.  Research and
development expenses for the six month period ended June 30, 1998 increased 91%
to $3,571,000 from $1,869,000 in the same period in 1997.  The increase is due
primarily to staff additions and associated expenses in research and development
and clinical and regulatory areas incurred as the Company increased human
resources to meet development program goals and increased expenses for clinical
trials in both Europe and the U.S.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the quarter ended June 30, 1998
increased 20% to $1,980,000 from $1,646,000 in the same period in 1997.
Selling, general and administrative expenses for the six month period ended June
30, 1998 increased 35% to $4,027,000 from $2,976,000 in the same period in 1997.
Selling expenses for the quarter ended June 30, 1998 increased 47% to $853,000
from $582,000 in the same period in 1997.  Selling expenses for the six month
period ended June 30, 1998 increased 70% to $1,793,000 from $1,057,000 in the
same period in 1997.  The increase is due primarily to costs associated with the
expansion of the Company's U.S. sales force, the ongoing establishment of a
direct sales force in several major markets in Europe and the commencement of
clinical trials, which requires training of participating physicians by sales
and clinical specialists.  General and administrative expenses for the quarter
ended June 30, 1998 decreased two percent to $620,000 from $631,000 in the same
period in 1997.  General and administrative expenses for the six month period
ended June 30, 1998 increased 18% to $1,286,000 from $1,094,000 in the same
period in 1997.  The decrease for the quarter ended June 30, 1998 is due
primarily to lower recruiting expenses in 1998 compared to expenses incurred 

                                       10
<PAGE>
 
in the same period in 1997. The increase for the six month period ended June 30,
1998 is due primarily to additional staff and expenses related to the
requirements of a public company. Marketing expenses for the quarter ended June
30, 1998 increased 17% to $507,000 from $433,000 in the same period in 1997.
Marketing expenses for the six month period ended June 30, 1998 increased 15% to
$948,000 from $825,000 in the same period in 1997. The increase is due primarily
to additional staff and expenses related to the development of marketing
materials and programs to address new product introductions.

Interest and Other Income

Interest and other income for the quarter ended June 30, 1998 remained at the
same level of  $110,000 as in the same period in 1997.  Interest and other
income for the six month period ended June 30, 1998 increased to $254,000 from
$135,000 in the same period in 1997.  The increase for the six month period
ended June 30, 1998 is due primarily to larger cash and cash equivalent balances
as a result of the Company's initial public offering in June 1997.

Interest Expense

Interest expense for the quarter ended June 30, 1998 increased to $40,000 from
$28,000 in the same period in 1997.  Interest expense for the six month period
ended June 30, 1998 decreased to $76,000 from $81,000 in the same period in
1997.  The increase for the quarter ended June 30, 1998 is due primarily to
higher borrowing levels for purchases of capital equipment.  The decrease for
the six month period ended June 30, 1998, compared to the same period in 1997 is
due primarily to the conversion of all Notes Payable into shares of series E
preferred stock in March 1997.

LIQUIDITY AND CAPITAL RESOURCES

The Company has financed its operations to date principally through private
placements of equity securities, which have yielded net proceeds of $32.1
million as of June 30, 1998, together with interest income on such proceeds, an
initial public offering of Common Stock in June 1997, which yielded net proceeds
of approximately $13.6 million, and equipment leases, which have totaled $2.6
million for the acquisition of certain capital equipment.  As of June 30, 1998,
the Company had approximately $5.0 million in cash and cash equivalents.

Net cash used in operating activities was approximately $7.7 million and $5.0
million for the six months ended June 30, 1998 and 1997, respectively, resulting
primarily from operating losses incurred during such periods.  Net cash provided
by investing activities was approximately $3.9 million for the six months ended
June 30, 1998, which was attributable primarily to maturities and sales of
short-term investments.   Net cash used was approximately $717,000 for the six
months ended June 30, 1997, which was attributable primarily to capital
expenditures.  Net cash provided by financing activities was approximately
$196,000 and $25.3 million for the six months ended June 30, 1998 and 1997,
respectively, resulting primarily from the Company's financing equipment through
its established lease line, the Company's sale of equity securities in private
placement transactions and the Company's initial public offering in June 1997.

In February 1998, the Company entered into an equipment lease that permits the
Company up to $1.5 million of financing for the purchase of office and
manufacturing equipment, software and custom-built equipment.  In June 1998, the
Company secured a $3.0 million line of credit which may be used for general

                                       11
<PAGE>
 
working capital purposes.  As of June 30, 1998, $1.0 million and $3.0 million of
borrowing capacity remained available to the Company under these lines.  The
Company's future liquidity and capital requirements will depend upon numerous
factors, including the progress of the Company's product development efforts,
the progress of the Company's clinical trials, actions relating to regulatory
matters, the costs and timing of expansion of product development,
manufacturing, sales and marketing activities, the extent to which the Company's
products gain market acceptance, and competitive developments.  The Company
believes that available cash, a line of credit and lease lines will be
sufficient to meet the Company's operating expenses and capital requirements
through the balance of 1998.  There can be no assurance, however, that the
Company will not require additional financing during that period, or that if
required, such additional financing will be available on terms acceptable to the
Company, if at all.  The Company may seek to raise additional funds through
public or private financing, collaborative relationships or other arrangements.
There can be no assurance that such additional funding, if needed, will be
available on terms acceptable to the Company, if at all.  Furthermore, any
additional equity financing may be dilutive to stockholders, and debt financing,
if available, may involve restrictive covenants.  Collaborative arrangements, if
necessary to raise additional funds, may require the Company to relinquish its
rights to certain of its technologies, products or marketing territories.  The
failure of the Company to raise capital when needed would have a material
adverse effect on the Company's business, financial condition and results of
operations.

FACTORS AFFECTING FUTURE RESULTS

History of Losses and Expectation of Substantial Future Losses

Since inception, the Company has experienced losses and expects to experience
substantial net losses for the foreseeable future.  To date, sales of the
Company's microcatheter systems have been limited.  The Company had net losses
of approximately $12.3 million and $7.8 million for the Company's fiscal years
ended 1997 and 1996, respectively, and $7.6 million for the six months ended
June 30, 1998.  As of June 30, 1998, the Company had an accumulated deficit of
approximately $38.1 million.  The Company expects to incur substantial net
operating losses for the foreseeable future as a result of research and product
development, clinical trials, manufacturing, sales, marketing and other expenses
expected to be incurred as the Company further develops, seeks regulatory
approvals, tests and distributes its microcatheter systems.  The Company's
limited operating history makes accurate prediction of future operating results
difficult or impossible.  There can be no assurance that the Company will ever
generate substantial revenue or achieve profitability.  Failure by the Company
to generate substantial revenues would have a material adverse effect on the
Company's business, financial condition and results of operations.



Future Additional Capital Requirements;  No Assurance Future Capital Will be
Available

The Company's future liquidity and capital requirements will depend on numerous
factors, including: the progress of the Company's clinical research and product
development programs; the receipt of, and the time required to obtain,
regulatory clearances and approvals; the costs and timing of expansion of
product development, manufacturing and sales and marketing activities; the
extent to which the Company's products gain market acceptance; competitive
developments; and other factors.  In February 1998, the 

                                       12
<PAGE>
 
Company entered into an equipment lease agreement that permits the Company to
finance up to $1.5 million of office and manufacturing equipment, software and
custom built equipment. In June 1998, the Company secured a $3.0 million line of
credit which may be used for general working capital purposes. As of June 30,
1998, $1.0 million and $3.0 million of borrowing capacity remained available to
the Company under these lines. The Company believes that available cash, a line
of credit and lease lines will be sufficient to meet the Company's operating
expenses and capital requirements through the balance of 1998. In addition, if
unforeseen difficulties arise in the course of developing its products,
performing clinical trials, obtaining necessary regulatory clearances and
approvals or other aspects of the Company's business, the Company may be
required to invest greater-than-anticipated funds. As a consequence, the Company
will be required to raise additional funds through public or private debt or
equity financings, collaborative relationships, bank facilities or other
arrangements. There can be no assurance that, if additional financing is needed,
it will be available on terms acceptable to the Company, if at all. Any
additional equity financing may be dilutive to stockholders, and debt financing,
if available, may involve restrictive covenants.

No Assurance of Safety and Effectiveness; Early Stage of Product Development

To date, the Company has completed two clinical trials and has received three
510(k) pre-market clearances from the FDA with respect to its Cardima Pathfinder
and Pathfinder Mini microcatheter systems for venous mapping of VT and
Revelation microcatheter system for mapping and pacing of the atria.  The
Company also received 510(k) clearance for the Vueport guiding catheter in June
1998 and is seeking 510(k) clearance for its Tracer mapping catheter and its
Naviport deflectable tip guiding catheter.  Failure to obtain clearances for the
Company's other diagnostic products and guiding catheters under development on a
timely basis would have a material adverse effect on the Company's business,
financial condition and results of operations.

The Company is in the early stage of developing, testing and obtaining
regulatory approval for its microcatheter systems designed for ablation of AF
and VT.  The Company is currently developing the Revelation Tx microcatheter
system for ablation of AF and the Therastream microcatheter system for ablation
of VT.  The Company is required to obtain an IDE from the FDA prior to
conducting human clinical trials of its microcatheter systems for ablation.  The
Company filed an IDE for clinical testing of the Revelation microcatheter system
for the mapping and ablation of AF in January 1997.  The Company completed the
mapping phase of this feasibility study in August 1997 and began treating the
first patient in the ablation phase with the Revelation Tx microcatheter system
in March 1998.  The Company currently expects to file an IDE to begin clinical
testing of its Therastream microcatheter system for VT ablation in 1998.  The
Company must complete these clinical trials and a pivotal trial, if initiated,
prior to the filing of a PMA, and must receive PMA approval prior to marketing
such products for ablation in the United States.  Clinical trials of the
Company's microcatheter systems will require substantial financial and
management resources of the Company and the completion of such trials will take
several years.  There can be no assurance that necessary IDEs will be granted by
the FDA, that human clinical trials, if initiated, will be completed or that
these clinical studies will validate the results of the Company's pre-clinical
studies or demonstrate that such products are safe and effective.  In addition,
the clinical trials may identify significant technical or other obstacles to be
overcome prior to obtaining necessary regulatory approvals or market acceptance.
The failure of the Company to initiate and complete clinical trials, demonstrate
product safety and clinical effectiveness, or obtain regulatory approval for the
use of the Company's microcatheter systems for the ablation of AF or VT would
have a material adverse effect on the Company's business, financial condition
and results of operations.

Uncertainty of Product and Procedure Acceptance

                                       13
<PAGE>
 
The Company's microcatheter systems represent a novel approach to the mapping
and ablation of AF and VT.  Acceptance of the Company's products and procedures
by physicians, patients and health care payors will be necessary in order for
the Company to be successful.  The Company's microcatheter systems for the
mapping and ablation of AF and VT are new technologies that must compete with
more established treatments such as drugs, external electrical cardioversion and
defibrillation, implantable defibrillators, purposeful destruction of the Atrio-
Ventricular ("AV") node followed by implantation of a pacemaker, and open heart
surgery.  It is likely that physicians will not recommend the use of the
Company's microcatheter systems unless they conclude, based on clinical data and
other factors, that these systems provide a safe, effective and cost-efficient
alternative to established or emerging approaches to the mapping and ablation of
AF and VT.  Although the Company has received regulatory clearance to market the
Cardima Pathfinder and Pathfinder Mini microcatheter systems for mapping VT and
the Revelation microcatheter system for mapping AF, none of the products
currently being developed by Cardima for ablation of AF and VT has received
regulatory approval in the United States.  Even if the Company's ablation
products are successfully developed and the required regulatory approvals are
obtained, there can be no assurance that such products and the associated
procedures will ultimately gain any significant degree of market acceptance.
Since the Company's sole product focus is to design and market microcatheter
systems to map and ablate AF and VT, the failure to successfully commercialize
these systems would have a material and adverse affect on the Company's
business, financial condition and results of operations.

Risks Regarding Products and Procedures Designed for Mapping and Ablation of AF

Cardima is developing its Revelation Tx microcatheter system for mapping and
ablation of AF.  Currently, there is considerable clinical debate about the need
for mapping AF prior to ablation, and no mapping is performed during the open
heart surgical maze procedure.  However, the Company believes that mapping prior
to ablation may be useful to identify different segments of the AF population,
each of which could require slightly different mapping and ablation procedures.
For example, some electrophysiologists believe most AF patients will need to be
mapped and ablated in both the left and right atria, while others believe only
the right atrial intervention is warranted.  Market acceptance of this product
for mapping will depend largely on a determination that there is a clinical need
for diagnostic mapping prior to ablation of AF.  The Revelation Tx ablation
procedure may require the use of RF energy in both the right and left atria to
produce lesions.  In general, the use of RF energy in the left atrium has the
potential to create blood clots, which could travel through the vasculature to
the brain and may cause a stroke.  Consequently, physicians may not recommend
this procedure, in which event the Revelation Tx  would be unlikely to gain
market acceptance.  The failure of the Company to complete development of the
Revelation Tx  or to gain regulatory approval with respect to the Revelation Tx
for ablation of AF, demonstrate safety, clinical effectiveness or cost
effectiveness, gain wide market acceptance or successfully commercialize the
Revelation Tx for the mapping and ablation of AF would have a material adverse
effect on the Company's business, financial condition and results of operations.

                                       14

Risks Regarding Products and Procedures Designed for Mapping and Ablation of VT

The Cardima Pathfinder and Tracer microcatheter systems for VT mapping are
designed for use inside the vasculature of the heart wall and to provide access
to the vasculature of the heart through the venous system.  To achieve market
acceptance, the Company will need to demonstrate the safety and cost
effectiveness of the Cardima Pathfinder and Tracer microcatheter systems for VT
mapping, of which there can be no assurance.  In addition, electrophysiologists
will need to be specially trained to perform this procedure, which may further
impede market acceptance.  There can be no assurance that the Cardima Pathfinder
or Tracer microcatheter systems for VT mapping will ever achieve market
acceptance, or in the case of the Tracer microcatheter system, be cleared for
marketing by the FDA, or be successfully commercialized in the United States or
internationally.  The inability of the Company to gain wide market acceptance or
successfully commercialize the Cardima Pathfinder and Tracer microcatheter
systems for VT mapping would have a material adverse effect on the Company's
business, financial condition and results of operations.

The Company's Therastream microcatheter system is being developed for ablation
of VT using RF energy, which could cause damage to the arteries and veins of the
heart, potentially leading to myocardial infarction and even death.
Consequently, physicians may not recommend this procedure, in which event the
Therastream would be unlikely to gain market acceptance.  Failure of the Company
to gain market acceptance or successfully commercialize the Therastream would
have a material adverse effect on the Company's business, financial condition
and results of operations.

Fluctuations in Operating Results

The Company's results of operations may fluctuate significantly from quarter to
quarter or year to year depending upon a number of factors, including actions
relating to regulatory matters, progress of pre-clinical and clinical trials,
the extent to which the Company's products gain market acceptance, the scale-up
of manufacturing capabilities, the expansion of sales and marketing activities,
competition, the timing of new product introductions by the Company or its
competitors and the ability of the Company to market its products successfully
in the United States and internationally.  Although the Cardima Pathfinder and
Tracer microcatheter systems are labeled for single use only, the Company is
aware that some physicians are reusing these products. Reuse of the Company's
microcatheter systems would reduce revenues from product sales and could have a
material adverse effect on future performance and periodic operating results.
Due to such fluctuations in operating results, period to period comparisons of
the Company's revenues and operating results are not necessarily meaningful and
should not be relied upon as indicators of likely future performance or annual
operating results.

No Assurance of Obtaining Required Regulatory Approvals; Government Regulation

The pre-clinical and clinical testing, manufacturing, labeling, distribution and
promotion of the Company's products are subject to extensive and rigorous
government regulation in the United States and other countries.  Noncompliance
with applicable requirements can result in enforcement actions by the FDA
including, among other things, fines, injunctions, civil penalties, recall or
seizure of products, refusal of the FDA to grant pre-market clearances or
approvals, withdrawal of marketing approvals and criminal prosecution.  Any such
action would have a material adverse effect on the Company's business, financial
condition and results of operations.

The Company is prohibited from marketing its products in the United States
unless it obtains 510(k) clearance or PMA approval from the FDA.  The Company
believes that it usually takes up to 12 months 

                                       15
<PAGE>
 
from submission to obtain 510(k) clearance, but that it can take longer. The
Cardima Pathfinder and Cardima Pathfinder Mini microcatheter systems for mapping
VT and Revelation microcatheter system for mapping AF have each received 510(k)
clearance. The Company believes that its other mapping products will also be
eligible for 510(k) clearance, and has submitted a 510(k) pre-market
notification for the Tracer product. The Company has also submitted a 510(k) 
pre-market notification for the Naviport deflectable tip guiding catheter. These
submissions may need to include clinical trial data. There can be no assurance,
however, that any of these types of products will receive 510(k) clearance in a
timely fashion, if at all. Delays in market introduction resulting from the
510(k) clearance process could have a material adverse effect on the Company's
business, financial condition and results of operations.

The Company will be required to seek PMA approval for its ablation products,
including the Revelation Tx  and the Therastream microcatheters for ablation.
The process of obtaining PMA approval is much more costly, lengthy and uncertain
than the 510(k) clearance process.  The Company believes that the FDA's review
of a PMA application after filing can last from one to three years, or even
longer.  In order to prepare a PMA application, the Company will be required to
complete clinical trials to demonstrate the safety and effectiveness of these
products. The Company submitted an IDE for the Revelation microcatheter system
for mapping and ablation of AF in January 1997, and completed a mapping study at
Stanford University Hospital and Massachusetts General Hospital in September
1997.  In addition, the Company received conditional IDE approval in January
1998 and full approval in March 1998 for a feasibility clinical study for AF
ablation using the Revelation Tx microcatheter system.  The Company expects to
file an additional IDE and begin its clinical trials for the Therastream
microcatheter system in the second half of 1998.  There can be no assurance that
any clinical study that the Company proposes will be permitted by the FDA, will
be completed or, if completed, will provide data and information that supports
additional clinical investigations of the type necessary to obtain PMA approval.
The Company expects that a PMA application will not be submitted for at least
one year, if at all.  No assurance can be given that the Company will ever be
able to obtain PMA approval for any of its ablation products.  Failure of the
Company to obtain timely PMA approval would have a material adverse effect on
the Company's business, financial condition and results of operations.

The Company is subject to periodic inspection by the FDA and the California
Department of Health Services, and must comply with various other regulatory
requirements that apply to medical devices marketed in the United States,
including labeling regulations, the Quality System Regulation ("QSR") (which
includes elaborate testing, control, documentation and other quality assurance
procedures), the Medical Device Reporting regulation (which requires that a
manufacturer report to the FDA certain types of adverse events involving its
products), and the FDA's prohibitions against promoting approved products for
unapproved ("off-label") uses.  The Company's failure to comply with applicable
regulatory requirements could result in enforcement action by the FDA, which
could have a material adverse effect on the Company's business, financial
condition and results of operations.

Sales of medical devices outside the United States are subject to international
regulatory requirements that vary from country to country.  The time required
for approval varies from country to country and may be longer or shorter than
the time required in the United States.  The Company has obtained the requisite
approvals by means of the CE mark and TGA approval to sell the Cardima
Pathfinder, Cardima Pathfinder Mini, Revelation and Tracer for mapping in the
European Union ("EU") and Australia, respectively, to sell the Cardima
Pathfinder, Cardima Pathfinder Mini, Revelation and Tracer in Japan and to sell
the Cardima Pathfinder, Tracer, Vueport and Naviport in Canada.  The Company 
also received CE mark approval on August 4, 1998 to sell the Revelation
microcatheter for treatment of AF in the EU. The Company has ongoing clinical
trials in the EU for its AF ablation products, and has submitted this data to
support its application for CE mark. There can be no assurance the Company will
be successful in obtaining such approvals.
                                       16
<PAGE>
 
Failure to receive approval to affix the CE mark would prohibit the Company from
selling these products in member countries of the EU, and would require
significant delays in obtaining individual country approvals. No assurance can
be given that such approvals will ever be obtained. In such event, the Company's
business, financial condition and results of operations would be materially and
adversely affected.

Rapid Technological Change; Significant Competition

The medical device industry is characterized by rapid and significant
technological change.  Accordingly, the Company's success will depend in part on
its ability to respond quickly to medical discoveries and technological changes,
including changes in the capital equipment with which the Company's
microcatheter systems are designed to be compatible.  Product development
involves a high degree of risk, and there can be no assurance that the Company's
new product development efforts will result in any commercially successful
products.  Failure by the Company to respond to and develop new technologies
could have a material adverse effect on the Company's business, financial
condition and results of operations.

The Company's microcatheter systems for the mapping and ablation of AF and VT
are new technologies that must compete with more established treatments such as
drugs, external electrical cardioversion and defibrillation, implantable
defibrillators, purposeful destruction of the AV node followed by implantation
of a pacemaker, and open heart surgery.  In the market for cardiac mapping and
ablation devices, the Company believes that the primary competitive factors are
safety, effectiveness, ease of use and overall system cost.  In addition, the
length of time required for products to be developed and to receive regulatory
and, in some cases, reimbursement approval are important competitive factors.
Several of the Company's competitors are currently marketing and selling
catheters in the United States and internationally that map and ablate a type of
arrhythmia known as supraventricular tachycardia ("SVT").  In addition, several
competitors are also developing new approaches and new products for the mapping
and ablation of AF and VT.  These approaches include mapping systems using
contact mapping, single-point spatial mapping and non-contact, multi-site
electrical mapping technologies, and ablation systems using RF, ultrasound,
microwave, laser and cryoablation technologies.  In addition, companies are
developing surgical procedures that could potentially be used by physicians to
perform the open heart surgical maze procedure for the treatment of AF in a
minimally invasive manner.  If any of these new approaches or new products prove
to be safe and effective, the Company's products could be rendered
noncompetitive or obsolete, which could have a material adverse effect on the
Company's business, financial condition and results of operations.

Many of the Company's competitors have an established presence in the field of
interventional cardiology and electrophysiology, including Boston Scientific,
C.R. Bard, Inc., Johnson & Johnson, through its Cordis division, St. Jude
Medical, Inc., through its Daig division, and Medtronic, Inc.  These competitors
have substantially greater financial and other resources than the Company,
including larger research and development staffs and more experience and
capabilities in conducting research and development activities, testing products
in clinical trials, obtaining regulatory approvals, and manufacturing, marketing
and distributing products.  In addition, other companies are developing
proprietary systems for the diagnosis and treatment of cardiac arrhythmias,
including Biosense, Inc. a division of Johnson and Johnson, Cardiac Pathways,
Inc. and Endocardial Solutions, Inc.  Other companies develop, market and sell
alternative approaches to the treatment of AF and VT, including Guidant
Corporation, Medtronic, Inc., and Ventritex, Inc., a subsidiary of St. Jude,
Inc., the leading manufacturers of implantable defibrillators.  There can be no
assurance that the Company will succeed in developing and marketing technologies
and products that are more clinically effective and cost-effective than the more
established 

                                       17
<PAGE>
 
treatments or the new approaches and products being developed and marketed by
its competitors. Furthermore, there can be no assurance the Company will succeed
in developing new technologies and products that are available prior to its
competitors' products. Failure of the Company to demonstrate the competitive
advantages of its products would have a material adverse effect on the Company's
business, financial condition and results of operations.

Dependence on Patents and Proprietary and Licensed Technology; Risk of Patent
Infringement

The Company's success will depend in part on its ability to obtain patent
protection for its products and processes, to preserve its trade secrets,
trademarks, copyrights and to operate without infringing or violating the
proprietary rights of others.  The Company's strategy is to actively pursue
patent protection in the United States and foreign jurisdictions for technology
that it believes to be proprietary and that offers a potential competitive
advantage for its products.  The patent positions of medical device companies,
including the Company, are uncertain and involve complex and evolving legal and
factual questions.  The coverage sought in a patent application either can be
denied or significantly reduced before or after the patent is issued.  In
addition, the United States patent laws were recently amended to exempt
physicians, other health care professionals and affiliated entities from
infringement liability for medical and surgical procedures performed on
patients.  The Company cannot predict whether this amendment might have a
material adverse effect on the Company's ability to protect its proprietary
methods and procedures.

The Company relies on certain license agreements through which it licenses
certain technology from others, including technology of Target Therapeutics,
Inc., a subsidiary of Boston Scientific Corporation, ("Target") that is
integrated into the Company's microcatheter systems for mapping and ablation.
Under a license agreement with Target (the "Target License Agreement"), the
Company has an exclusive license (the "Target License") under certain issued
United States patents.  The Target License covers the diagnosis and treatment of
electrophysiological disorders in areas other than the central nervous system.
The Target License will terminate upon the expiration or invalidation of all
claims under the underlying patents.  In addition, the Company has obtained a
non-exclusive license to use Target's technology, provided it has made a
substantial improvement of such technology, for the diagnosis or treatment of
diseases of the heart, other than using balloon angioplasty.  Under the Target
License Agreement, Cardima has granted Target an exclusive, royalty-free license
to use any technology developed by Cardima prior to May 1996 in the fields of
neurology, interventional neuroradiology, interventional radiology, diagnosis
and treatment of male and female reproductive disorders and vascular prostheses.
The Target License Agreement imposes various commercialization, sublicensing,
insurance, royalty, product liability, indemnification, non-competition and
other obligations on the Company.  Failure by the Company to comply with certain
of these requirements could result in a termination of the Target License.  The
loss of the Company's exclusive rights to the Target-based microcatheter
technology would have a material adverse effect on the Company's business,
financial condition and results of operations.

The Company has also licensed a proprietary surface coating material used on
certain of its catheters.  There can be no assurance that these licenses will
continue to be available to the Company.  The loss of or inability to maintain
any of these licenses could result in delays in commercial shipments by the
Company until equivalent technology could be developed internally or identified,
licensed and integrated, which would have a material adverse effect on the
Company's business, financial condition and results of operations.

Although the Company has not received any significant letters from others
threatening to enforce intellectual property rights against the Company, there
can be no assurance that the Company will not 

                                       18
<PAGE>
 
become subject to patent infringement claims or litigation, to interference
proceedings in the USPTO to determine the priority of inventions or to
oppositions to patent grants in foreign jurisdictions. An adverse determination
in litigation, interference or opposition proceedings to which the Company may
become a party could subject the Company to significant liabilities to third
parties, require disputed rights to be licensed from third parties or require
the Company to cease using such technology. Under the Company's license
agreement with Target, the Company is not indemnified against claims brought by
third parties alleging infringement of patent rights. Consequently, the Company
could bear the liability resulting from such claims. There can be no assurance
that the Company will have the financial resources to protect and defend its
intellectual property, as such defense is often costly and time-consuming.
Failure of the Company to protect its patent rights, trade secrets, know-how or
other intellectual property could have a material adverse effect on the
Company's business, financial condition and results of operations.

The validity and breadth of claims in medical technology patents involve complex
legal and factual questions and, therefore, may be highly uncertain.  There can
be no assurance that any issued patent or patents based on pending patent
applications or any future patent application will exclude competitors or
provide competitive advantages to the Company, that any of the Company's patents
or patents in which it has licensed rights will be held valid if subsequently
challenged or that others will not claim rights in or ownership of the patents
and other proprietary rights held or licensed by the Company.  There can be no
assurance that others have not developed or will not develop similar products,
duplicate any of the Company's products or design around any patents issued to
or licensed by the Company or that may be issued in the future to the Company.
Since patent applications in the United States are maintained in secrecy until
patents issue, the Company cannot be certain that others were not the first to
file applications for inventions covered by the Company's pending patent
applications, nor can the Company be certain that it will not infringe any
patents that may be issued to others on such applications.  The Company
periodically reviews the scope of patents of which it is aware.  Although
Cardima does not believe that it is infringing patents known to the Company, the
question of patent infringement involves complex legal and factual issues and
there can be no assurance that any conclusion reached by the Company regarding
infringement will be consistent with the resolution of any such issues by a
court.

Risks Associated with International Sales

A number of risks are inherent in international transactions.  International
sales may be limited or disrupted by the imposition of government controls,
export license requirements, economic or political instability, trade
restrictions, changes in tariffs or difficulties in staffing and management.
Additionally, although the Company's sales are denominated in U.S. dollars,
Cardima's business, financial condition and results of operations may be
adversely affected by fluctuations in currency exchange rates as well as
increases in duty rates and difficulties in obtaining export licenses.  The
financial condition, expertise and performance of the Company's international
distributors and any future international distributors could affect sales of the
Company's products internationally and could have a material adverse effect on
the Company's business, financial condition and results of operations.  The
Company is in the process of hiring, training and establishing a direct sales
force in certain major European markets.  The ability of the Company to
effectively operate a remote sales force will require additional resources, time
and expense and could have a material adverse effect on the Company's business,
financial condition and results of operations.  The international nature of the
Company's business also subjects it and its employees, representatives, agents
and distributors to laws and regulations of the international jurisdictions in
which they operate or in which the Company's products may be sold.  The
regulation of medical devices in a number of such jurisdictions, particularly in
the EU, continues to develop, and there can be no assurance that new laws or
regulations will not have a material adverse effect on the Company's business,
financial 

                                       19
<PAGE>
 
condition and results of operations. Foreign regulatory agencies often establish
product standards different from those in the United States and any inability to
obtain foreign regulatory approvals on a timely basis could have a material
adverse effect on the Company's international business and its financial
condition and results of operations. In addition, the laws of certain foreign
countries do not protect the Company's intellectual property rights to the same
extent as do the laws of the United States. There can be no assurance that the
Company will be able to successfully commercialize any of its current
microcatheter products, including the Cardima Pathfinder, Cardima Pathfinder
Mini, Revelation and Tracer microcatheter systems, or any future product in any
foreign market.

Uncertainty Related to Third-Party Reimbursement

U. S. health care providers, including hospitals and physicians, that purchase
medical devices generally rely on third-party payors, principally federal
Medicare, state Medicaid and private health insurance plans, to reimburse all or
a part of the costs and fees associated with the procedures performed using
these devices.  The Company's success will depend upon, among other things, the
ability of health care providers to obtain satisfactory reimbursement from
third-party payors for medical procedures in which the Company's microcatheter
systems are used.  Third-party payors may deny reimbursement if they determine
that a prescribed device has not received appropriate regulatory clearances or
approvals, is not used in accordance with cost-effective treatment methods as
determined by the payor, or is experimental, unnecessary or inappropriate.  If
FDA clearance or approval is received, third-party reimbursement would also
depend upon decisions by the United States Health Care Financing Administration
for Medicare, as well as by individual health maintenance organizations, private
insurers and other payors.  Reimbursement systems in international markets vary
significantly by country and by region within some countries, and reimbursement
approvals may be obtained on a country-by-country basis.  Many international
markets have government managed health care systems that control reimbursement
for new devices and procedures.  In most markets, there are private insurance
systems as well as government managed systems.  There can be no assurance that
reimbursement for the Company's products will be available or, if available,
that such reimbursement will be available in sufficient amounts in the United
States or in international markets under either government or private
reimbursement systems, or that physicians will support and advocate
reimbursement for procedures using the Company's products.  Failure by hospitals
and other users of the Company's products to obtain reimbursement from third-
party payors or changes in government and private third-party payor policies
toward reimbursement for procedures employing the Company's products would have
a material adverse effect on the Company's business, financial condition and
results of operations.  Moreover, the Company is unable to predict what
additional legislation or regulation, if any, relating to the heath care
industry or third-party coverage and reimbursement may be enacted in the future,
or what effect such legislation or regulation would have on the Company.

Limited Manufacturing Experience; Scale-Up Risk; Need to Comply with United
States Manufacturing Standards; Dependence on Key Suppliers

The Company has only limited experience in manufacturing its microcatheter
systems.  The Company currently manufactures its microcatheter systems in
limited quantities for U. S. and international sales and for pre-clinical and
clinical trials.  The Company has no experience manufacturing its products in
the volumes that will be necessary for the Company to achieve significant
commercial sales, and there can be no assurance that reliable, high-volume
manufacturing capacity can be established or maintained at commercially
reasonable costs.  The Company has recently increased the number of
microcatheters manufactured and expects that, if United States sales for the
Cardima Pathfinder and Revelation microcatheter systems increase, or if the
Company receives FDA clearance or approvals for other 

                                       20
<PAGE>
 
products, it will need to expend significant capital resources and develop
manufacturing expertise to establish large-scale manufacturing capabilities.
Manufacturers often encounter difficulties in scaling up production of new
products, including problems involving production yields, quality control and
assurance, component supply shortages, shortages of qualified personnel,
compliance with FDA regulations, and the need for further FDA approval of new
manufacturing processes. In addition, the Company believes that substantial cost
reductions in its manufacturing operations will be required for it to
commercialize its microcatheter systems on a profitable basis. Any inability of
the Company to establish and maintain large-scale manufacturing capabilities
would have a material adverse effect on the Company's business, financial
condition and results of operations.

The Company's manufacturing facilities are subject to periodic inspection by
regulatory authorities, and its operations must either undergo QSR compliance
inspections conducted by the FDA or receive an FDA exemption from such
compliance inspections in order for the Company to be permitted to produce
products for sale in the United States.  The Company's facilities and
manufacturing processes are subject to inspections from time to time by the FDA,
State of California and TUV.  The Company has demonstrated compliance with ISO
9001 (EN 46001) quality standards, as well as compliance with 93/42/EEC, the
Medical Device Directive and is in compliance with procedures to produce
products for sale in Europe.  Any failure by the Company to comply with QSR
requirements or to maintain its compliance with ISO 9001 (EN 46001) standards
may result in the Company being required to take corrective actions, such as
modification of its policies and procedures.  In addition, the Company may be
required to cease all or part of its operations for some period of time until it
can demonstrate that appropriate steps have been taken to comply with QSR or ISO
9001 (EN 46001) standards.  There can be no assurance that the Company will be
found in compliance with QSR by regulatory authorities, or that it will continue
to comply with ISO 9001 (EN 46001) standards in future audits or that the
Company will not experience difficulties in the course of developing its
manufacturing capability.  Any failure of the Company to comply with state or
FDA QSR requirements or to maintain compliance with ISO 9001 (EN 46001)
standards, or to develop its manufacturing capability in compliance with such
standards, would have a material adverse effect on the Company's business,
financial condition and results of operations.

The Company purchases certain key components of its products, including the
hydrophilic coating for certain of its microcatheters, from sole, single or
limited source suppliers.  For certain of these components, there are relatively
few alternative sources of supply.  Establishing additional or replacement
suppliers for any of the numerous components used in the Company's products, if
required, may not be accomplished quickly and could involve significant
additional costs.  Any supply interruption from vendors or failure of the
Company to obtain alternative vendors for any of the numerous components used to
manufacture the Company's products would limit the Company's ability to
manufacture its products and would have a material adverse effect on the
Company's business, financial condition and results of operations.

Limited Sales, Marketing and Distribution Experience

The Company has only limited experience marketing and selling its products in
commercial quantities.  Expanding the Company's marketing and sales capability
to adequately support sales in commercial quantities will require substantial
effort and require significant management and financial resources.  The Company
has terminated several distribution arrangements in Europe and is in the process
of hiring a direct sales force in France and Germany.  The Company currently has
one salesman in Germany and there can be no assurance that the Company will be
able to build a European direct sales force, that establishing such a sales
force will be cost-effective or that the Company's European sales efforts will
be successful.  The Cardima Pathfinder, Pathfinder Mini, Revelation and Tracer
microcatheter systems for 

                                       21
<PAGE>
 
mapping of AF and VT have obtained regulatory approval in certain international
markets, and sales and marketing of these products is often conducted through
distributors. The Company received CE mark approval on August 4, 1998 to sell 
the Revelation microcatheter for treatment of AF in the EU. The Company
currently has a number of exclusive distributors that cover certain European
countries and Japan and has sold only a limited number of Cardima Pathfinder,
Revelation and Tracer microcatheter systems through these distributors. The
Company does not have written agreements with certain of its exclusive
distributors. Consequently, the terms of such arrangements, such as length of
arrangements and minimum purchase obligations, are uncertain. In addition, the
laws in certain international jurisdictions may make it difficult and costly for
the Company to terminate such distribution arrangements absent specific written
termination terms. There can be no assurance that these distributors will be
able to market and sell the Company's products in these markets. There can be no
assurance that the Company will be able to enter into additional agreements with
desired distributors on a timely basis or at all, or that such distributors will
devote adequate resources to selling the Company's products. Failure to
establish an adequate sales force or to establish and maintain appropriate
distribution relationships would have a material adverse effect upon the
Company's business, financial condition and results of operations.

Dependence Upon Key Personnel

The Company's ability to operate successfully depends in significant part upon
the continued service of certain key scientific, technical, clinical, regulatory
and managerial personnel, and its continuing ability to attract and retain
additional highly qualified personnel in these areas.  Competition for such
personnel is intense, especially in the San Francisco Bay Area, and there can be
no assurance that the Company can retain such personnel or that it can attract
or retain other highly qualified scientific, technical, clinical, regulatory and
managerial personnel in the future, including key sales and marketing personnel.

Risk of Product Liability; Adequacy of Insurance Coverage

The development, manufacture and sale of the Company's microcatheter systems may
expose the Company to product liability claims.  Although the Company has not
experienced any claims to date, there can be no assurance that the Company will
not experience losses due to product liability claims in the future.  Although
the Company currently has general liability insurance with coverage in the
amount of $1.0 million per occurrence, subject to a $2.0 million annual
limitation, and product liability insurance with coverage in the amount of $5.0
million per occurrence, subject to a $5.0 million annual limitation, there can
be no assurance that such coverage will continue to be available to the Company
on reasonable terms, if at all.  In addition, there can be no assurance that all
of the activities encompassed within the Company's business are or will be
covered under the Company's policies.  Although the Cardima Pathfinder,
Pathfinder Mini, Revelation and Tracer products are labeled for single use only,
the Company is aware that some physicians are reusing such products.  Moreover,
despite labeling of the Company's microcatheters for diagnostic use only, the
Company believes that physicians are using such mapping microcatheters for
ablation.  Multiple use or "off-label" use of the Company's microcatheters could
subject the Company to increased exposure to product liability claims, which
could have a material adverse effect on the Company's business, financial
condition and results of operations.  The Company may require additional product
liability coverage if the Company significantly expands commercialization of its
products.  Such additional coverage is expensive, difficult to obtain and may
not be available in the future on acceptable terms, if at all.  Any claims or
series of claims against the Company, regardless of their merit or eventual
outcome, could have a material adverse effect on the Company's business,
financial condition and results of operations.

Impact of the Year 2000 Issue on the Company's Operations

                                       22
<PAGE>
 
Many existing computer programs use only two digits to identify a year in the
date field.  These programs were designed and developed without considering the
impact of the upcoming change in the century.  If not corrected, many computer
applications could fail or create erroneous results by or at the Year 2000 (the
"Year 2000 Issue").  The Company is in the process of performing an assessment
of the potential impact of the Year 2000 Issue on its operations.  Management is
in the process of formalizing its assessment procedures and developing a plan to
address identified issues.  The Company has evaluated its financial and
accounting and inventory tracking systems and concluded that they are not
materially affected by the Year 2000 Issue.  The extent, if any, of the impact
of the Year 2000 Issue on the other systems and equipment is unknown.  A
corporate-wide inventory of computer applications is being performed by the
Company and is expected to be completed by the end of fiscal year 1998, after
which time the Company will attempt to remedy any issues.  The Company has also
begun communications with its facilities managers to determine the impact on
building security and related equipment.  There can be no assurance that all
third parties will address the Year 2000 Issue in a timely fashion, if at all.
Any Year 2000 Issue compliance problems of either the Company, its business
partners or its customers could have a material adverse effect on the Company's
business, operating results and financial condition.

          USE OF PROCEEDS FROM REGISTERED SECURITIES

          On June 6, 1997, a Registration Statement on Form S-1 (No. 333-23209)
          was declared effective by the SEC pursuant to which the Company issued
          2,275,000 shares of common stock.  The shares were sold for the
          account of the Company at a price of $7.00 per share, generating
          $15,925,000 in gross proceeds to the Company.  The initial public
          offering was managed by Bear Stearns & Company.

          From the effective date of the Registration Statement to June 30,
          1998, the Company incurred approximately $1,114,750 in underwriting
          discounts and commissions and approximately $2,285,609 of expenses
          paid to or for the underwriters and other related expenses.  The net
          proceeds of the offering, after deducting the foregoing expenses, were
          approximately $13,639,391.

          From the effective date of the Registration Statement to June 30,

                      MASTER LOAN AND SECURITY AGREEMENT


          THIS AGREEMENT dated as of June 19, 1998, is made by Cardima, Inc.
(the "Borrower"), a Delaware corporation having its principal place of business

          SECTION  5.1.    EXISTENCE, ETC.  The Borrower shall:  (a) retain its
existence and its current yearly accounting cycle, (b) maintain in full force
and effect all licenses, bonds, franchises, leases, trademarks, patents,
contracts, and other rights necessary or desirable to the profitable conduct of
its business unless the failure to do so could not reasonably be expected to
have a Material Adverse Effect on the Borrower, (c) continue in, and limit its
operations to, the same general lines of business as those presently conducted
by it, and (d) comply with all applicable laws and regulations of any federal,
state, or local governmental authority, except for such laws and regulations the
violations of which would not, in the aggregate, have a Material Adverse Effect
on the Borrower.

          SECTION  5.2.    NOTICE TO THE LENDER.  As soon as possible, and in
any event within five days after the Borrower learns of the following, the
Borrower will give written notice to the Lender of (a) any proceeding instituted
or threatened to be instituted by or against the Borrower in any federal, state,
local, or foreign court or before any commission or other regulatory body
(federal, state, local, or foreign) involving a sum, together with the sum
involved in all other similar proceedings, in excess of $50,000 in the
aggregate, (b) any contract that is terminated or amended and which has had or
could reasonably be expected to have a Material Adverse Effect on the Borrower,
(c) the occurrence of any Material Adverse Change with respect to the Borrower,
and (d) the occurrence of any Event of Default or event or condition which, with
notice or lapse of time or both, would constitute an Event of Default, together
with a statement of the action which the Borrower has taken or proposes to take
with respect thereto.

          SECTION   5.3.   MAINTENANCE OF BOOKS AND RECORDS.  The Borrower will
maintain books and records pertaining to the Collateral in such detail, form,
and scope as the Lender shall require in its commercially reasonable judgment.
The Borrower agrees that the Lender or its agents may enter upon the Borrower's
premises at any time and from time to time on reasonable notice during normal
business hours, and at any time upon the occurrence and continuance of an Event
of Default, for the purpose of inspecting the Collateral and any and all records
pertaining thereto.

          SECTION  5.4.    INSURANCE.  The Borrower will maintain insurance on
the Collateral under such policies of insurance, with such insurance companies,
in such amounts, and covering such risks as are at all times satisfactory to the
Lender.  All such policies shall be made payable to the Lender, in case of loss,
under a standard non-contributory "lender" or "secured party" clause and are to
contain such other provisions as the Lender may reasonably require to protect
the Lender's interests in the Collateral and to any payments to be made under
such policies.  Certificates of insurance policies are to be delivered to the
Lender, premium prepaid, with the loss payable endorsement in the Lender's
favor, and shall provide for not less than thirty days' prior written notice to
the Lender, of any alteration or cancellation of coverage.  If the Borrower
fails to maintain such insurance, the Lender may arrange for (at the Borrower's
expense and without any responsibility on the Lender's part for) obtaining the
insurance.  Unless the Lender shall otherwise agree with the Borrower in
writing, the Lender shall have the sole right, in the name of the Lender or the
Borrower, to file claims under any insurance policies, to receive and give
acquittance for any payments that may be payable thereunder, and to execute any
endorsements, receipts, releases, assignments, reassignments, or other documents
that may be necessary to effect the collection, compromise, or settlement of any
claims under any such insurance policies for loss or damage to the Collateral.

          SECTION  5.5.    TAXES.  The Borrower will pay, when due, all taxes,
assessments, claims, and other charges ("Taxes") lawfully levied or assessed
against the Borrower or the Collateral other than taxes that are being
diligently contested in good faith by the Borrower by appropriate proceedings
promptly instituted and for which an adequate reserve is being maintained by the
Borrower in accordance with GAAP.  If any Taxes remain unpaid after the date
fixed for the payment thereof, or if any lien shall be claimed therefor, then,
without notice to the Borrower, but on the Borrower's behalf, the Lender may pay
such Taxes, and the amount thereof shall be included in the Obligations.

          SECTION  5.6.    BORROWER TO DEFEND COLLATERAL AGAINST CLAIMS; FEES ON

                                       7
<PAGE>
 
COLLATERAL. The Borrower will defend the Collateral against all claims and
demands of all Persons at any time claiming the same or any interest therein.
The Borrower will not permit any notice creating or otherwise relating to liens
on the Collateral or any portion thereof to exist or be on file in any public
office other than Permitted Liens. The Borrower shall promptly pay, when
payable, all transportation, storage, and warehousing charges and license fees,
registration fees, assessments, charges, permit fees, and taxes (municipal,
state, and federal) which may now or hereafter be imposed upon the ownership,
leasing, renting, possession, sale, or use of the Collateral, other than taxes
on or measured by the Lender's income and fees, assessments, charges, and taxes
which are being contested in good faith by appropriate proceedings diligently
conducted and with respect to which adequate reserves are maintained to the
extent required by GAAP.

          SECTION   5.7.   NO CHANGE OF LOCATION, STRUCTURE, OR IDENTITY.  The
Borrower will not (a) change the location of its chief executive office or
establish any place of business other than those specified herein or (b) move or
permit the movement of any item of Collateral from the location specified in the
applicable Schedule, except that the Borrower may change its chief executive
office and keep Collateral at other locations within the United States provided
that the Borrower has delivered to the Lender (i) prior written notice thereof
and (ii) duly executed financing statements and other agreements and instruments
(all in form and substance satisfactory to the Lender) necessary or, in the
opinion of the Lender, desirable to perfect and maintain in favor of the Lender
a first priority security interest in the Collateral.  Notwithstanding anything
to the contrary in the immediately preceding sentence, the Borrower may keep any
Collateral consisting of motor vehicles or rolling stock at any location in the
United States provided that the Lender's security interest in any such
Collateral is conspicuously marked on the certificate of title thereof and the
Borrower has complied with the provisions of Section 5.9.

          SECTION  5.8.    USE OF COLLATERAL; LICENSES; REPAIR.  The Collateral
shall be operated by competent, qualified personnel in connection with the
Borrower's business purposes, for the purpose for which the Collateral was
designed and in accordance with applicable operating instructions, laws, and
government regulations, and the Borrower shall use every reasonable precaution
to prevent loss or damage to the Collateral from fire and other hazards.  The
Collateral shall not be used or operated for personal, family, or household
purposes.  The Borrower shall procure and maintain in effect all orders,
licenses, certificates, permits, approvals, and consents required by federal,
state, or local laws or by any governmental body, agency, or authority in
connection with the delivery, installation, use, and operation of the
Collateral.

          SECTION  5.9.    FURTHER ASSURANCES.  The Borrower will, promptly upon
request by the Lender, execute and deliver or use its best efforts to obtain any
document required by the Lender (including, without limitation, warehouseman or
processor disclaimers, mortgagee waivers, landlord disclaimers, or subordination
agreements with respect to the Obligations and the Collateral), give any
notices, execute and file any financing statements, mortgages, or other
documents (all in form and substance satisfactory to the Lender), mark any
chattel paper, deliver any chattel paper or instruments to the Lender, and take
any other actions that are necessary or, in the opinion of the Lender, desirable
to perfect or continue the perfection and the first priority of the Lender's
security interest in the Collateral, to protect the Collateral against the
rights, claims, or interests of any Persons, or to effect the purposes of this
Agreement.  The Borrower hereby authorizes the Lender to file one or more
financing or continuation statements, and amendments thereto, relating to all or
any part of the Collateral without the signature of the Borrower where permitted
by law.  A carbon, photographic, or other reproduction of this Agreement or any
financing statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law.  To the extent
required under this Agreement, the Borrower will pay all costs incurred in
connection with any of the foregoing.

          SECTION  5.10.   NO DISPOSITION OF COLLATERAL.  The Borrower will not
in any way hypothecate or create or permit to exist any lien, security interest,
charge, or encumbrance on or other interest in any of the Collateral, except for
the lien and security interest granted hereby and Permitted Liens which are
junior to the lien and security interest of the Lender, and the Borrower will
not sell, transfer, assign, pledge, collaterally assign, exchange, or otherwise
dispose of any of the Collateral.  In the event the Collateral, or any part
thereof, is sold, transferred, assigned, exchanged, or otherwise disposed of in
violation of these provisions, the security interest of the Lender shall
continue in such Collateral or part thereof notwithstanding such sale, transfer,
assignment, exchange, or other disposition, and the Borrower will hold the
proceeds thereof in a separate account for the benefit 

                                       8
<PAGE>
 
of the Lender. Following such a sale, the Borrower will transfer such proceeds
to the Lender in kind.

          SECTION  5.11.   NO LIMITATION ON LENDER'S RIGHTS.  The Borrower will
not enter into any contractual obligations which could be reasonably expected to
restrict or inhibit the Lender's rights or ability to sell or otherwise dispose
of the Collateral or any part thereof.

          SECTION  5.12.   PROTECTION OF COLLATERAL.  Upon reasonable notice to
the Borrower (provided that if an Event of Default has occurred and is
continuing the Lender need not give any notice), the Lender shall have the right
at any time to make any payments and do any other acts the Lender may deem
necessary to protect its security interests in the Collateral, including,
without limitation, the rights to satisfy, purchase, contest, or compromise any
encumbrance, charge, or lien which, in the reasonable judgment of the Lender,
appears to be prior to or superior to the security interests granted hereunder,
and appear in, and defend any action or proceeding purporting to affect its
security interests in, or the value of, any of the Collateral.  The Borrower
hereby agrees to reimburse the Lender for all payments made and expenses
incurred under this Agreement including fees, expenses, and disbursements of
attorneys and paralegals (including the allocated costs of in-house counsel)
acting for the Lender, including any of the foregoing payments under, or acts
taken to protect its security interests in, any of the Collateral, which amounts
shall be secured under this Agreement, and agrees it shall be bound by any
payment made or act taken by the Lender hereunder absent the Lender's gross
negligence or willful misconduct.  The Lender shall have no obligation to make
any of the foregoing payments or perform any of the foregoing acts.

          SECTION  5.13.   DELIVERY OF ITEMS.  The Borrower will (a) promptly
(but in no event later than one Business Day) after its receipt thereof, deliver
to the Lender any documents or certificates of title issued with respect to any
property included in the Collateral, and any promissory notes, letters of credit
or instruments related to or otherwise in connection with any property included
in the Collateral, which in any such case come into the possession of the
Borrower, or shall cause the issuer thereof to deliver any of the same directly
to the Lender, in each case with any necessary endorsements in favor of the
Lender and (b) deliver to the Lender as soon as available copies of any and all
press releases and other similar communications issued by the Borrower.

          SECTION  5.14.  SOLVENCY.  The Borrower shall be and remain
Solvent at all times.

          SECTION  5.15.   FUNDAMENTAL CHANGES.  The Borrower shall not (a)
amend or modify its name, unless the Borrower delivers to the Lender thirty days
prior to any such proposed amendment or modification written notice of such
amendment or modification and within ten days before such amendment or
modification delivers executed Uniform Commercial Code financing statements (in
form and substance satisfactory to the Lender); (b) merge or consolidate with
any other entity, without the Lender's prior written consent which shall not be
unreasonably withheld; or (c) permit a change, other than a change which results
from the sale of newly issued securities to investors, in more than 35% of the
ownership of any equity interests of the Borrower on the date hereof without the
Lender's prior written consent which shall not be unreasonably withheld.  In the
event that Lender declines in writing to consent to a proposed merger,
consolidation or change in ownership, then Borrower shall have the right to
prepay the Loans without penalty.

          SECTION  5.16.   RIGHT OF FIRST OFFER.  If and when, before the
payment and satisfaction in full of all Obligations, Borrower seeks revolving
working capital financing secured by its accounts receivable, Borrower will so
notify Lender and permit Lender to make a proposal to provide such financing.
Lender must reply to Borrower's notice within 15 days of the date of such
notice, indicating whether Lender accepts or declines to make such proposal.
Borrower will be required to accept Lender's proposal if the terms and
conditions of the proposal are no less favorable to Borrower than any other
proposal received by Borrower.

          SECTION  5.17.   ADDITIONAL REQUIREMENTS.  The Borrower shall take all
such further actions and execute all such further documents and instruments as
the Lender may reasonably request.

    SECTION  6.  FINANCIAL STATEMENTS.  Until the payment and satisfaction
                 --------------------

and be continuing:

          (a) The Lender may, without prejudice to any of its other rights under
any Loan Document or Applicable Law, declare all Obligations to be immediately
due and payable (except with respect to any Event of Default set forth in

in each provision of this Agreement of which time is an element.  All terms not
defined herein or in a Note shall have the meaning set forth in the applicable
Code, except where the context otherwise requires.  To the extent a term or
provision of this Agreement conflicts with any Note, or any term or provision
thereof, and is not dealt with herein with more specificity, this Agreement
shall control with respect to the subject matter of such term or provision.
Acceptance of or acquiescence in a course of performance rendered under this

even though the accepting or acquiescing party had knowledge of the nature of
the performance and opportunity for objection.

create a continuing security interest in the Collateral and shall (i) remain in

and hold harmless the Lender and its directors, officers, agents, employees, and
counsel from and against any and all costs, expenses, claims, or liability
(except costs incurred in negotiating and executing this Agreement) incurred by
the Lender or such Person hereunder and under any other Loan Document or in
connection herewith or therewith, unless such claim or liability shall be due to
willful misconduct or gross negligence on the part of the Lender or such Person.

          SECTION  9.10.   COUNTERPARTS; TELECOPIED SIGNATURES.  This Agreement
may be executed in counterparts, each of which when so executed and delivered
shall be an original, but both of which shall together constitute one and the
same instrument.  This Agreement and each of the other Loan Documents and any
notices given in connection herewith or therewith may be executed and delivered
by telecopier or other facsimile transmission all with the same force and effect
as if the same was a fully executed and delivered original manual counterpart.

          SECTION  9.11.   SEVERABILITY.  In case any provision in or obligation
under this Agreement or any Note or any other Loan Document shall be invalid,
illegal, or unenforceable in any jurisdiction, the validity, legality, and
enforceability of the remaining provisions or obligations, or of such provision
or obligation in any other jurisdiction, shall not in any way be affected or
impaired thereby.

          SECTION  9.12.   DELAYS; PARTIAL EXERCISE OF REMEDIES.  No delay or
omission of the Lender to exercise any right or remedy hereunder, whether before
or after the happening of any Event of Default, shall impair any such right or
shall operate as a waiver thereof or as a waiver of any such Event of Default.
No single or partial exercise by the Lender of any right or remedy shall
preclude any other or further exercise thereof, or preclude any other right or
remedy.

          SECTION  9.13.   ENTIRE AGREEMENT.  The Borrower and the Lender agree
that this Agreement, the Schedule hereto, and the Commitment Letter are the
complete and exclusive statement and agreement between the parties with respect
to the subject matter hereof, superseding all proposals and prior agreements,

to the subject matter hereof.  Should there exist any inconsistency between the

Right of First Offer:    If and when, during the term of the Loan, Borrower
- --------------------     seeks revolving working capital financing secured by
                         its accounts receivable, Borrower will so notify Lender
                         and permit Lender to make a proposal to provide such
                         financing. Lender must reply to Borrower's notice
                         within 15 days of the date of such notice, indicating
                         whether Lender accepts or declines to make such
                         proposal. Borrower will be required to accept Lender's
                         proposal if the terms and conditions of the proposal
                         are no less favorable to Borrower than any other
                         proposal received by Borrower.

Loan Prepayment:         Borrower may prepay the Loan any time after the first
- ---------------          12 months of the term. A prepayment premium of 4% of
                         the principal amount being prepaid will be charged for
                         prepayments made during months 13-24 and 2% for
                         prepayments made during months 25-36.

Warrant Coverage:        As an inducement to the Lender to enter into this
- ----------------         financing, the Borrower will provide to Lender warrants
                         to acquire shares of the Borrower's common stock having
                         an aggregate exercise price equal to $300,000. The
                         exercise price per share will be the trading price of
                         the shares at the close of the market on the date
                         hereof. The warrants will be exercisable for a period
                         of five years. Lender will have the option to exercise
                         the Warrants without payment of the exercise price and
                         receive only that number of shares which represents the
                         value of the difference between the fair market value
                         of the shares and the exercise price (i.e. "net
                         issuance" or "cashless exercise"). 

Conditions Precedent     Each Loan will be subject to the following:
- --------------------     1.  No material adverse change in the financial
to Lending:                  condition, operations or prospects of the Borrower

                             Lender's counsel.
                         3.  Results of all legal due diligence, including lien,
                             judgment and tax search and other matters Lender

                             Lender's counsel.
                         4.  Lender shall receive a valid and perfected first
                             priority lien and security interest in the
                             Collateral and Lender shall have received

                             the Collateral except as expressly permitted
                             herein.

          THIS INTELLECTUAL PROPERTY SECURITY AGREEMENT is made and entered into
as of this 19th day of June, 1998 (this "Agreement"), between CARDIMA, INC., a
Delaware corporation (the "Grantor"), with and in favor of TRANSAMERICA BUSINESS
CREDIT CORPORATION, a Delaware corporation (the "Lender").

          WHEREAS, the Grantor is entering into a Master Loan and Security
Agreement dated as of even date herewith (as amended, supplemented or otherwise
modified from time to time, the "Loan Agreement"; terms which are capitalized
herein and not otherwise defined shall have the meanings given to them in the
Loan Agreement) with the Lender, pursuant to which the Lender agreed to make
loans and advances to the Grantor, subject to the terms and conditions set forth
in the Loan Agreement; and

          WHEREAS, under the Loan Agreement, the Grantor has granted to the
Lender a security interest in and lien on substantially all of its assets; and

          WHEREAS, it is a condition precedent to the effectiveness of the Loan
Agreement that the Grantor shall have executed and delivered this Agreement and
granted a security interest in all of the Grantor's right, title and interest in
and to all of the Intellectual Property Collateral (as hereinafter defined) in
favor of the Lender, as contemplated hereby.

          NOW, THEREFORE, in consideration of the premises hereof and to induce

Collateral").

          SECTION 2.  Representations, Warranties and Covenants of the Grantor.
                      -------------------------------------------------------- 

          (a) The Grantor is and will continue to be the owner of all of the
Intellectual Property Collateral, except as set forth in Schedule D, free from
any adverse claim, security interest, lien or encumbrance in favor of any Person
except for the security interest granted to the Lender and except for Permitted
Liens.

          (b) None of the Intellectual Property Collateral is or shall become
subject to any Lien in favor of any Person other than the Lender and except for
any Permitted Liens, and the Grantor agrees that it shall not license, transfer,
convey or encumber any interest in or to the Intellectual Property Collateral.
Notwithstanding the foregoing, the Grantor shall be permitted to license any of
the Trademarks on a non-exclusive basis in the ordinary course of business to
(i) third parties for the sole purpose of manufacturing, marketing, advertising,
distributing, or selling goods that are not manufactured, marketed, advertised,
distributed, or sold by the Grantor, or (ii) third parties that do not
manufacture, market, advertise, distribute, or sell goods in the United States
or to others for sale in the United States.  Any license of the Intellectual
Property Collateral granted by the Grantor (each, a "License") shall be in
writing and shall reserve all rights in the Grantor except those reasonably
necessary in the ordinary course of business to fulfill the permitted purposes
herein.  The Grantor shall cause a copy of each License to be delivered to the
Lender within thirty (30) days of execution by all parties thereto.

                                       2
<PAGE>
 
          (c) Except as disclosed in Schedule D hereto, the Grantor has made no
previous assignment, transfer or agreement in conflict herewith or constituting
a present or future assignment, transfer, or encumbrance of any of the
Intellectual Property Collateral.

          (d) Except as disclosed in Schedule D hereto, there is no financing
statement or other document or instrument now signed or on file in any public
office granting a security interest in or otherwise encumbering any part of the
Intellectual Property Collateral, except those showing the Lender as secured
party.  So long as any Obligations remain outstanding, the Grantor will not
execute, and there will not be on file in any public office, any such financing
statement or other document or instruments, except financing statements filed or
to be filed in favor of the Lender.

          (e) Subject to any limitation stated therein or in connection
therewith, all information furnished to the Lender concerning the Intellectual
Property Collateral and proceeds thereof is and will be accurate and correct in
all material respects.

          (f) Except as disclosed in Schedule D hereto, to the Company's
knowledge, all Intellectual Property Collateral consisting of applications for
Patents and for registrations of Trademarks and Copyrights has been duly and
properly filed and all Intellectual Property Collateral consisting of issued or
granted Patents and of registrations of Trademarks and Copyrights (including,
without limitation, any and all renewals, reissues, continuations or divisions
thereof, as the case may be) has been duly and properly maintained.

          (g) Promptly upon the receipt of an official filing receipt indicating
that a patent application or an application for registration of a trademark has
been received by the U.S. Patent and Trademark Office or an application for
registration of a copyright has been received by the U.S. Copyright Office and
upon the issuance of any patent or of any trademark or copyright registration,
the Grantor agrees to notify the Lender in writing, which notice shall identify
such patent, trademark or copyright application or patent, trademark or
copyright registration, and the Grantor shall execute all documents necessary to
perfect a security interest in such patent, trademark or copyright application
or such patent or trademark or copyright registration, and the Grantor shall
annually, or more frequently as the Lender shall request, cause an instrument
sufficient to perfect, protect or establish any Lien hereunder to be recorded in
the U.S. Patent and Trademark Office with respect to all United States patent
applications filed by it or patents issued to it during the prior calendar year
and with respect to all trademark applications filed by it or trademark
registrations issued to it during the prior calendar year, and the Grantor shall
annually, or more frequently as the Lender shall request, cause an instrument
sufficient to perfect, protect or establish any Lien hereunder to be recorded in
the U.S. Copyright Office with respect to United States copyright applications
filed by it or copyright registrations issued to it during the prior calendar
year.

          (h) The Grantor shall not intentionally take any action, or permit any
action to be taken by others subject to the Grantor's control, including
licensees, or fail to take any action, or permit others subject to the Grantor's
control, including licensees, to fail to take any action, subject to the
provisions of Section 2(g), which would, in the case of any such actions or
failures to act taken singly or together, adversely affect the validity, grant
and enforceability of the security interest granted to the Lender hereunder.
Notwithstanding the foregoing, the Grantor shall be permitted to abandon any of
the Trademarks in accordance with the terms of Section 2(l).

          (i) The Grantor shall promptly notify the Lender, in writing, of any
suit, action, proceeding, claim or counterclaim brought against the Grantor that
would reasonably be expected to affect adversely the Intellectual Property
Collateral, and shall, on request, deliver to the Lender a copy of all
pleadings, papers, orders or decrees theretofore and thereafter filed in any
such suit, action or proceeding, and shall keep the Lender duly advised in
writing of the progress of any such suit.

          (j) To the best knowledge and belief of the Grantor, no infringement
or unauthorized use presently is being made of any Intellectual Property
Collateral.  The Grantor has advised the Lender of its trademark monitoring and
enforcement program.  In the event of any material infringement of the

                                       3

<PAGE>
 
Intellectual Property Collateral by others or in the event of any other conduct
detrimental to the Intellectual Property Collateral by others known or brought
to the attention of the Grantor, the Grantor shall promptly notify the Lender in
writing at its address set forth in Section 5(a) of such infringement or other
conduct and the full nature, extent, evidence and facts of such infringement or
other conduct known to the Grantor.

          (k) If requested by the Lender, the Grantor shall provide the Lender a
complete status report of all Intellectual Property Collateral.  Upon request by
the Lender, the Grantor shall deliver to counsel for the Lender copies of any
such Intellectual Property Collateral and other documents concerning or related
to the prosecution, protection, maintenance, enforcement and issuance of the
Intellectual Property Collateral.

          (l) The Grantor shall notify the Lender in writing at the address set
forth in Section 5(a) prior to any proposed voluntary abandonment (which is not
in furtherance of an application for another Patent) of any Intellectual
Property Collateral (other than items of Intellectual Property Collateral that
are not useful or beneficial to the business and operations of the Grantor) and
obtain the prior written consent of the Lender to such abandonment.

          (m) During the term of this Agreement, the Grantor agrees:

                  (i)   whenever any of the registered Trademarks are used by or
          on behalf of the Grantor, if reasonably practicable, to affix or cause
          to be affixed a notice that the mark is a registered trademark or
          service mark, which notice shall be in a form accepted or required by
          the trademark marking laws of each country in which the mark is so
          used and registered; and

                  (ii)  whenever any of the underlying works covered by
          registered Copyrights are used by or on behalf of the Grantor, if
          reasonably practicable, to affix or cause to be affixed a notice that
          said underlying works are so covered, which notice shall be in a form
          accepted or required by the copyright laws of such country in which
          said underlying works are so used and registered.

          (n)   Subject to the provisions of Section 4(g), during the term of
this Agreement, all income, royalties, payments and damages due and payable to
the Grantor under or in respect of the Intellectual Property Collateral shall be
paid to the Grantor.

          (o) The Grantor agrees, upon the reasonable request by the Lender,
during the term of this Agreement:

                  (i)  to execute, acknowledge and deliver all additional
          instruments and documents necessary or desirable to effect the
          purposes and intents of this Agreement, in a form reasonably
          acceptable to counsel for the Lender; and

                  (ii) to do all such other acts as may be necessary or
          appropriate to carry out the purposes and intents of this Agreement,
          and to create, evidence, perfect and continue the security interests
          of the Lender in the Intellectual Property Collateral.

          SECTION 3.  Indemnity.  The Grantor agrees to indemnify the Lender
                      ---------                                             
from and against any and all claims, losses and liabilities arising out of or
resulting from this Agreement (including, without limitation, enforcement of
this Agreement and any actions taken pursuant to Section 4 or any failure to act
thereunder).

          SECTION 4.  Rights and Remedies Upon an Event of Default.
                      -------------------------------------------- 

          (a)   If any Event of Default shall have occurred and be continuing,
then and in every such case, subject to any mandatory Requirements of Law, the
Lender, in addition to other rights and remedies provided for herein and any
rights now or hereafter existing under applicable law, shall have all rights and
remedies as a secured creditor under the Uniform Commercial Code in all relevant
jurisdictions and may:

                                       4

<PAGE>
 
                  (i)  personally, or by agents or attorneys, immediately take
          possession of the Intellectual Property Collateral or any part
          thereof, from the Grantor or any other Person who then has possession
          of any part thereof, with or without notice or process of law, and for
          that purpose may enter upon the Grantor's premises where any of the
          Intellectual Property Collateral is located and remove the same and
          use in connection with such removal any and all services, supplies,
          aids and other facilities of the Grantor; and

                  (ii)  sell, assign or otherwise liquidate, or direct the
          Grantor to sell, assign or otherwise liquidate, any or all of the
          Intellectual Property Collateral or any part thereof, and take
          possession of the proceeds of any such sale or liquidation;

                  (b) Any collateral repossessed by the Lender under or pursuant
to Section 4(a), may be sold, assigned, leased or otherwise disposed of under
one or more contracts or as an entirety, and without the necessity of gathering
at the place of sale the property to be sold, and in general in such manner, at
such time or times, at such place or places and on such terms as the Lender may,
in compliance with any Requirements of Law, determine to be commercially
reasonable. Any such disposition which shall be a private sale or other private
proceedings permitted by such requirements shall be made upon not less than 30
days' written notice to the Grantor specifying the time at which such
disposition is to be made and the intended sale price or other consideration
therefor, and shall be subject, for the 10 days after the giving of such notice,
to the right of the Grantor or any nominee of the Grantor to acquire the
Intellectual Property Collateral involved at a price or for such other
consideration at least equal to the intended sale price or other consideration
so specified. Any such disposition which shall be a public sale permitted by
such requirements shall be made upon not less than 30 days' written notice to
the Grantor specifying the time and place of such sale and, in the absence of
applicable Requirements of Law, shall be by public auction (which may, at the
option of the Lender, be subject to reserve), after publication of notice of
such auction not less than 10 days prior thereto in two newspapers of general
circulation in the jurisdiction in which such auction is to be held. To the
extent permitted by any such Requirements of Law, the Lender may bid for and
become the purchaser of the Intellectual Property Collateral or any item
thereof, offered for sale in accordance with this Section without accountability
to the Grantor (except to the extent of surplus money received). If, under
mandatory Requirements of Law, the Lender shall be required to make disposition
of the Intellectual Property Collateral within a period of time which does not
permit the giving of notice to the Grantor as hereinabove specified, the Lender
need give the Grantor only such notice of disposition as shall be reasonably
practicable in view of such mandatory Requirements of Law. The Lender shall not
be obligated to make any sale of Intellectual Property Collateral regardless of
notice of sale having been given. The Lender may adjourn any public or private
sale from time to time by announcement at the time and place fixed therefor, and
such sale may, without further notice, be made at the time and place to which it
was so adjourned.

                 (c) Upon the occurrence and continuance of an Event of Default,
the Lender shall have the right at any time to make any payments and do any
other acts the Lender may deem necessary to protect its security interests in
the Intellectual Property Collateral, including, without limitation, the rights
to pay, purchase, contest or compromise any Lien which, in the reasonable
judgment of the Lender, appears to be prior to or superior to the security
interests granted hereunder, and appear in and defend any action or proceeding
purporting to affect its security interests in, or the value of, the
Intellectual Property Collateral. The Grantor hereby agrees to reimburse the
Lender for all payments made and expenses incurred under this Agreement
including reasonable fees, expenses and disbursements of attorneys and
paralegals acting for the Lender, including any of the foregoing payments under,
or acts taken to protect its security interests in, the Intellectual Property
Collateral, which amounts shall be secured under this Agreement, and agrees it
shall be bound by any payment made or act taken by the Lender hereunder absent
the Lender's gross negligence or willful misconduct. The Lender shall have no
obligation to make any of the foregoing payments or perform any of the foregoing
acts.

                  (d) The Grantor hereby irrevocably authorizes and appoints the
Lender, or any Person or agent the Lender may designate, as the Grantor's
attorney-in-fact, with full authority in the place and stead of the Grantor and
in the name of the Grantor or otherwise, at the Grantor's cost and expense, in
the Lender's discretion, to take any action and to execute any instrument that
the Lender may deem necessary or advisable to 

                                       5

<PAGE>
 
accomplish the purposes and intents of this Agreement and to exercise all of the
following powers upon and at any time after the occurrence and during the
continuance of an Event of Default, which powers, being coupled with an
interest, shall be irrevocable until all of the Obligations shall have been paid
and satisfied in full:

                  (i)    ask for, demand, collect, bring suit, recover,
          compromise, administer, accelerate or extend the time of payment,
          issue credits, compromise, receive and give acquittance and receipts
          for moneys due and to become due under or in respect of any of the
          Intellectual Property Collateral;

                  (ii)   receive, take, endorse, negotiate, sign, assign and
          deliver and collect any checks, notes, drafts or other instruments,
          documents and chattel paper, in connection with clause (i) above;

                  (iii)  receive, open and dispose of all mail addressed to the
          Grantor and notify postal authorities to change the address for
          delivery thereof to such address as the Lender may designate;

                  (iv)   give customers indebted on the Intellectual Property
          Collateral notice of the Lender's interest therein, or to instruct
          such customers to make payment directly to the Lender for the
          Grantor's account or to request, at any time from customers indebted
          on the Intellectual Property Collateral, verification of information
          concerning the Intellectual Property Collateral and the amounts owing
          thereon;

                  (v)    convey any item of Intellectual Property Collateral to
          any purchaser thereof;

                  (vi)   record any instruments under Section 2(g) hereof;

                  (vii)  make any payments or take any acts under Section 4(c)
          hereof; and

                  (viii) file any claims or take any action or institute any
          proceedings that the Lender may reasonably deem necessary or desirable
          for the collection of any of the Intellectual Property Collateral or
          otherwise to enforce the rights of the Lender with respect to any of
          the Intellectual Property Collateral.

The Lender's authority under this Section 4(d) shall include, without
limitation, the authority to execute and give receipt for any certificate of
ownership or any document, transfer title to any item of Intellectual Property
Collateral, sign the Grantor's name on all financing statements or any other
documents deemed necessary or appropriate to preserve, protect or perfect the
security interest in the Intellectual Property Collateral and to file the same,
prepare, file and sign the Grantor's name on any notice of Lien, assignment or
satisfaction of Lien or similar document in connection with any Intellectual
Property Collateral and prepare, file and sign the Grantor's name on a proof of
claim in bankruptcy or similar document against any customer of the Grantor, and
to take any other actions arising from or incident to the rights, powers and
remedies granted to the Lender in this Agreement.  This power of attorney is
coupled with an interest and is irrevocable by the Grantor.

                  (e) All cash proceeds received by the Lender in respect of any
sale of, collection from, or other realization upon all or any part of the
Intellectual Property Collateral shall be applied by the Lender against the
Obligations in such order as the Lender may determine.

                  (f) The Lender shall have the right of setoff with respect to
the Intellectual Property Collateral as provided Section 9.14 of the Loan
Agreement.

                  (g) Upon the occurrence and during the continuance of an Event
of Default, all income, royalties, payments and damages under or in respect of
the Intellectual Property Collateral, if any, received thereafter shall be held
by the Grantor in trust for the benefit of the Lender, separate from the
Grantor's own property or funds and immediately turned over to the Lender with
proper assignments or endorsements. Upon the 

                                       6

<PAGE>
 
occurrence and during the continuance of an Event of Default, the Lender shall
have the right to notify payors of income, royalties, payments and damages under
or in respect of the Intellectual Property Collateral to make payment directly
to the Lender.

          (h) Each and every right, power and remedy hereby specifically given
to the Lender shall be in addition to every other right, power and remedy
specifically given under this Agreement or under the other Loan Documents or now
or hereafter existing at law or in equity, or by statute, and each and every
right, power and remedy whether specifically herein given or otherwise existing
may be exercised from time to time or simultaneously and as often and in such
order as may be deemed expedient by the Lender. All such rights, powers and
remedies shall be cumulative and the exercise or the beginning of exercise of
one shall not be deemed a waiver of the right to exercise of any other or
others. No delay or omission of the Lender in the exercise of any such right,
power or remedy and no renewal or extension of any of the Obligations shall
impair any such right, power or remedy or shall be construed to be a waiver of
any Default or Event of Default or any acquiescence therein.

          (b)    Headings.  The headings in this Agreement are for purposes of
                 --------                                                     
reference only and shall not affect the meaning or construction of any provision
of this Agreement.

          (c)    Severability.  The provisions of this Agreement are severable,
                 ------------                                                  
and if any clause or provision shall be held invalid or unenforceable in whole
or in part in any jurisdiction, then such invalidity or unenforceability shall
affect, in that jurisdiction only, such clause or provision, or part thereof,
and shall not in any manner affect such clause or provision in any other
jurisdiction or any other clause or provision of this Agreement in any
jurisdiction.

          (d) Amendments, Waivers and Consents.  Any amendment or waiver of any
              --------------------------------                                 
provision of this Agreement and any consent to any departure by the Grantor from

specificity, the Loan Agreement shall control with respect to the subject matter
of such term or provision.  Acceptance of or acquiescence in a course of
performance rendered under this Agreement shall not be relevant in determining
the meaning of this Agreement even though the accepting or acquiescing party had
knowledge of the nature of the performance and opportunity for objection.

          (f) Continuing Security Interest.  This Agreement shall create a
              ----------------------------                                
continuing security interest in the Intellectual Property Collateral and shall
(i) remain in full force and effect until the payment in full in cash of the
Obligations and the termination of the Loan Agreement, (ii) be binding upon the
Grantor and its successors and assigns and (iii) inure, together with the rights
and remedies of the Lender, to the Lender's successors, transferees and assigns.
Without limiting the generality of the foregoing clause (iii), the Lender may,
in accordance with the terms of the Loan Agreement, assign or otherwise transfer
all or any portion of its rights and obligations under the Loan Documents
(including, without limitation, all or any portion of any Loans or any Notes
held by it) to any other Person, and such other Person shall thereupon become
vested with all the benefits in respect thereof granted to the Lender herein or
otherwise, in each case as provided in the Loan Agreement.

          (g) Reinstatement.  To the extent permitted by law, this Agreement
              -------------                                                 
shall continue to be effective or be reinstated if at any time any amount
received by the Lender in respect of the Obligations is rescinded or must
otherwise be restored or returned by the Lender because the Grantor is the
subject of an Insolvency Event, all as though such payments had not been made.

          (h)    Survival of Provisions.  All representations, warranties and
                 ----------------------                                      
covenants of the Grantor contained herein shall survive the execution and
delivery of this Agreement, and shall terminate only upon the full and final
payment and performance by the Grantor of the Obligations secured hereby and
termination of the Loan Agreement and the other Loan Documents.

          (i)    Lender May Perform.  If the Grantor fails to perform any
                 ------------------                                      
agreement contained herein, the Lender may itself perform, or cause performance
of, such agreement, and the expenses of the Lender incurred in connection
therewith shall be payable by the Grantor and shall constitute Obligations
secured by this Agreement.

          (j) No Duty on Lender.  The powers conferred on the Lender hereunder
              -----------------                                               
are solely to protect the interest of the Lenders in the Intellectual Property
Collateral and shall not impose any duty upon the Lender to exercise any such
powers.  Except for the safe custody of any Intellectual Property Collateral in
its possession and the accounting for money actually received by it hereunder,
the Lender shall have no duty as to any Intellectual Property Collateral, as to
ascertaining or taking action with respect to calls, conversions, exchanges,
maturities, tenders or other matters related to any Intellectual Property
Collateral, whether or not the Lender has or is deemed to have knowledge of such
matters, or as to the taking of any necessary steps to preserve rights against
any Person or any other rights pertaining to any Intellectual Property
Collateral.  The Lender shall be deemed to have exercised reasonable care in the
custody and preservation of any Intellectual Property Collateral in its
possession if such Intellectual Property Collateral is accorded treatment
substantially equal to that which the Lender accords its own property.  To the
extent the Intellectual Property Collateral is held by a custodian, the Lender
shall be deemed to have exercised reasonable care if it has selected the
custodian with reasonable care.

          (k) Delays; Partial Exercise of Remedies.  No delay or omission of the
              ------------------------------------                              
Lender to exercise any right or remedy hereunder, whether before or after the
happening of any Event of Default, shall impair any such right or shall operate
as a waiver thereof or as a waiver of any such Event of Default.  No single or
partial exercise by the Lender of any right or remedy shall preclude any other
or further exercise thereof, or preclude any other right or remedy.

          (l)    Release; Termination of Agreement.  Subject to the provisions
                 ---------------------------------                            
of subsection (g) hereof, upon the payment in full of the Obligations and the
termination of the Loan Agreement, this Agreement shall terminate and all rights
in the Intellectual Property Collateral shall revert to the Grantor.  At such
time, the Lender shall, upon the request and at the expense of the Grantor, (A)
execute and deliver to the Grantor such documents as the Grantor shall
reasonably request to evidence such termination and (B) reassign and redeliver
to the Grantor all of the Intellectual Property Collateral hereunder which has
not been sold, disposed of, retained or applied by the Lender in accordance with
the terms hereof.  Such reassignment and redelivery shall be without warranty by
or recourse to the Lender, except as to the absence of any prior assignments by
the Lender of its interest in the Intellectual Property Collateral.

together constitute one and the same agreement.

          (n) GOVERNING LAW.  THE VALIDITY, INTERPRETATION AND ENFORCEMENT OF
              -------------                                                  
THIS AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF ILLINOIS, WITHOUT
GIVING EFFECT TO CONFLICT OF LAW PRINCIPLES, EXCEPT TO THE EXTENT THAT FEDERAL
LAW IS APPLICABLE.

          (o) SUBMISSION TO JURISDICTION.  ALL DISPUTES BETWEEN THE GRANTOR AND
              --------------------------                                       
THE LENDER, WHETHER SOUNDING IN CONTRACT, TORT, EQUITY OR OTHERWISE, SHALL BE
RESOLVED ONLY BY STATE AND FEDERAL COURTS LOCATED IN CHICAGO, ILLINOIS AND THE
COURTS TO WHICH AN APPEAL THEREFROM MAY BE TAKEN; PROVIDED, HOWEVER, THAT THE
LENDER SHALL HAVE THE RIGHT, TO THE EXTENT PERMITTED BY APPLICABLE LAW, TO
PROCEED AGAINST THE GRANTOR OR ITS PROPERTY IN ANY LOCATION REASONABLY SELECTED
BY THE LENDER IN GOOD FAITH TO ENABLE THE LENDER TO REALIZE ON SUCH PROPERTY, OR
TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF THE LENDER.  THE GRANTOR
AGREES THAT IT WILL NOT ASSERT ANY PERMISSIVE COUNTERCLAIMS, SETOFFS OR CROSS-
CLAIMS IN ANY PROCEEDING BROUGHT BY THE LENDER.  THE GRANTOR WAIVES ANY
OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE COURT IN WHICH THE LENDER HAS
COMMENCED A PROCEEDING, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE
LAYING OF VENUE OR BASED ON FORUM NON CONVENIENS.

          (p) JURY TRIAL.  THE GRANTOR AND THE LENDER EACH HEREBY WAIVES TO THE
              ----------                                                       
FULLEST EXTENT PERMITTED BY LAW ANY RIGHT TO A TRIAL BY JURY.

          IN WITNESS WHEREOF, the parties hereto have executed this Agreement by
causing this Agreement to be signed by their respective duly authorized officers
on the day and year first above written.

     --------------                                                         
Holder of this Warrant upon the exercise hereof.

SECTION 2.  EXERCISE OF WARRANT.
            ------------------- 

     2.1.  PROCEDURE FOR EXERCISE OF WARRANT.  To exercise this Warrant in whole
           ---------------------------------                                    
or in part (but not as to any fractional share of Common Stock), the Holder
shall deliver to the Company at its office referred to in Section 12 hereof at
any time and from time to time during the Term of this Warrant: (i) the Notice
of Exercise in the form attached hereto, (ii) cash, certified or official bank
check payable to the order of the Company, wire transfer of funds to the
Company's account, or evidence of any indebtedness of the Company to the Holder
(or any combination of any of the foregoing) in the amount of the Warrant Price
for each share being purchased, and (iii) this Warrant.  Notwithstanding any
provisions herein to the contrary, if the Current Market Price (as defined in
Section 5) is greater than the Warrant Price (at the date of calculation, as set
forth below), in lieu of exercising this Warrant as hereinabove permitted, the
Holder may elect to receive shares of Common Stock equal to the value (as
determined below) of this Warrant (or the portion thereof being canceled) by
surrender of this Warrant at the office of the Company referred to in Section 12
hereof, together with the Notice of Exercise, in which event the Company shall
issue to the Holder that number of shares of Common Stock computed using the
following formula:

                              CS = WCS x (CMP-WP)
                                   --------------
                                      CMP

Where

     CS  equals the number of shares of Common Stock to be issued to the Holder

     WCS  equals the number of shares of Common Stock purchasable under the
          Warrant or, if only a portion of the Warrant is being exercised,
          the portion of the Warrant being exercised (at the date of such
          calculation)

     CMP  equals the Current Market Price (at the date of such calculation)

     WP  equals the Warrant Price (as adjusted to the date of such calculation)

In the event of any exercise of the rights represented by this Warrant, a
certificate or certificates for the shares of Common Stock so purchased,
registered in the name of the Holder or such other name or names as may be
designated by the Holder, shall be delivered to the Holder hereof within a
reasonable time, not exceeding fifteen (15) days, after the rights represented
by this Warrant shall have been so exercised; and, unless this Warrant has
expired, a new Warrant representing the number of shares (except a remaining
fractional share), if any, with respect to which this Warrant shall not then
have been exercised shall also be issued to the Holder hereof within such time.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which the Warrant was
surrendered and payment of the Warrant Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder of
such shares at the close of business on the next succeeding date on which the
stock transfer books are open.

     2.2.  TRANSFER RESTRICTION LEGEND.  Each certificate for Warrant Shares
           ---------------------------                                      
shall bear the following legend (and any additional legend required by (i) any
applicable state securities laws and (ii) any securities exchange upon which
such Warrant Shares may, at the time of such exercise, be listed) on

                                      -2-
<PAGE>
 
the face thereof unless at the time of exercise such Warrant Shares shall be
registered under the Securities Act:

     "The shares represented by this certificate have not been registered under
     the Securities Act of 1933, as amended, and may not be sold or transferred
     in the absence of such registration or an exemption therefrom under said
     Act."

Any certificate issued at any time in exchange or substitution for any
certificate bearing such legend (except a new certificate issued upon completion
of a public distribution under a registration statement of the securities
represented thereby) shall also bear such legend unless, in the opinion of
counsel for the holder thereof (which counsel shall be reasonably satisfactory
to counsel for the Company) the securities represented thereby are not, at such
time, required by law to bear such legend.

SECTION 3.  COVENANTS AS TO COMMON STOCK.  The Company covenants and agrees that
            ----------------------------                                        
all shares of Common Stock that may be issued upon the exercise of the rights
represented by this Warrant will, upon issuance, be validly issued, fully paid
and nonassessable, and free from all taxes, liens and charges with respect to
the issue thereof.  The Company further covenants and agrees that it will pay
when due and payable any and all federal and state taxes which may be payable in
respect of the issue of this Warrant or any Common Stock or certificates
therefor issuable upon the exercise of this Warrant, subject to a maximum of
$3,000.  The Company further covenants and agrees that the Company will at all
times have authorized and reserved, free from preemptive rights, a sufficient
number of shares of Common Stock to provide for the exercise of the rights
represented by this Warrant.  The Company further covenants and agrees that if
any shares of capital stock to be reserved for the purpose of the issuance of
shares upon the exercise of this Warrant require registration with or approval
of any governmental authority under any federal or state law before such shares
may be validly issued or delivered upon exercise, then the Company will in good
faith and as expeditiously as possible endeavor to secure such registration or
approval, as the case may be.  If and so long as the Common Stock issuable upon
the exercise of this Warrant is listed on any national securities exchange, the
Company will, if permitted by the rules of such exchange, list and keep listed
on such exchange, upon official notice of issuance, all shares of such Common
Stock issuable upon exercise of this Warrant.

SECTION 4.  ADJUSTMENT OF NUMBER OF SHARES. Upon each adjustment of the Warrant
            ------------------------------                                     
Price as provided in Section 5, the Holder shall thereafter be entitled to
purchase, at the Warrant Price resulting from such adjustment, the number of
shares of Common Stock (calculated to the nearest tenth of a share) obtained by
multiplying the Warrant Price in effect immediately prior to such adjustment by
the number of shares of Common Stock purchasable pursuant hereto immediately
prior to such adjustment and dividing the product thereof by the Warrant Price
resulting from such adjustment.

SECTION 5.  ADJUSTMENT OF WARRANT PRICE.  The Warrant Price shall be subject to
            ---------------------------                                        
adjustment from time to time as follows:

     (i)  If, at any time during the Term of this Warrant, the number of shares
of Common Stock outstanding is increased by a stock dividend payable in shares
of Common Stock or by a subdivision or split-up of shares of Common Stock, then,
following the record date fixed for the determination of holders of Common Stock
entitled to receive such stock dividend, subdivision or split-up, the Warrant
Price shall be appropriately decreased so that the number of shares of Common
Stock issuable upon the exercise hereof shall be increased in proportion to such
increase in outstanding shares.

                                      -3-
<PAGE>
 
     (ii)  If, at any time during the Term of this Warrant, the number of shares
of Common Stock outstanding is decreased by a combination of the outstanding
shares of Common Stock, then, following the record date for such combination,
the Warrant Price shall appropriately increase so that the number of shares of
Common Stock issuable upon the exercise hereof shall be decreased in proportion
to such decrease in outstanding shares.

     (iii)  In case, at any time during the Term of this Warrant, the Company
shall declare a cash dividend upon its Common Stock payable otherwise than out
of earnings or earned surplus or shall distribute to holders of its Common Stock
shares of its capital stock (other than Common Stock), stock or other securities
of other persons, evidences of indebtedness issued by the Company or other
persons, assets (excluding cash dividends and distributions) or options or
rights (excluding options to purchase and rights to subscribe for Common Stock
or other securities of the Company convertible into or exchangeable for Common
Stock), then, in each such case, immediately following the record date fixed for
the determination of the holders of Common Stock entitled to receive such
dividend or distribution, the Warrant Price in effect thereafter shall be
determined by multiplying the Warrant Price in effect immediately prior to such
record date by a fraction of which the numerator shall be an amount equal to the
difference of (x) the Current Market Price of one share of Common Stock minus
(y) the fair market value (as determined by the Board of Directors of the
Company, whose determination shall be conclusive) of the stock, securities,
evidences of indebtedness, assets, options or rights so distributed in respect
of one share of Common Stock, and of which the denominator shall be such Current
Market Price.

     (iv)  All calculations under this Section 5 shall be made to the nearest
cent or to the nearest one-tenth (1/10) of a share, as the case may be.

     (v)  For the purpose of any computation pursuant to this Section 5, the
Current Market Price at any date of one share of Common Stock shall be deemed to
be the average of the daily closing prices for the 15 consecutive business days
ending on the last business day before the day in question (as adjusted for any
stock dividend, split, combination or reclassification that took effect during
such 15 business day period).  The closing price for each day shall be the last
reported sales price regular way or, in case no such reported sales took place
on such day, the average of the last reported bid and asked prices regular way,
in either case on the principal national securities exchange on which the Common
Stock is listed or admitted to trading or as reported by Nasdaq (or if the
Common Stock is not at the time listed or admitted for trading on any such
exchange or if prices of the Common Stock are not reported by Nasdaq then such
price shall be equal to the average of the last reported bid and asked prices on
such day as reported by The National Quotation Bureau Incorporated or any
similar reputable quotation and reporting service, if such quotation is not
reported by The National Quotation Bureau Incorporated); provided, however, that
if the Common Stock is not traded in such manner that the quotations referred to
in this clause (v) are available for the period required hereunder, the Current
Market Price shall be determined in good faith by the Board of Directors of the
Company or, if such determination cannot be made, by a nationally recognized
independent investment banking firm selected by the Board of Directors of the
Company (or if such selection cannot be made, by a nationally recognized
independent investment banking firm selected by the American Arbitration
Association in accordance with its rules).

     (vi)  Whenever the Warrant Price shall be adjusted as provided in Section
5, the Company shall prepare a statement showing the facts requiring such
adjustment and the Warrant Price that shall be in effect after such adjustment.
The Company shall cause a copy of such statement to be sent by mail, first class
postage prepaid, to each Holder of this Warrant at its, his or her address
appearing on the 
                                      -4-
<PAGE>
 
Company's records. Where appropriate, such copy may be given in advance and may
be included as part of the notice required to be mailed under the provisions of
subsection (viii) of this Section 5.

     (vii)  Adjustments made pursuant to clauses (i), (ii) and (iii) above shall
be made on the date such dividend, subdivision, split-up, combination or
distribution, as the case may be, is made, and shall become effective at the
opening of business on the business day next following the record date for the
determination of stockholders entitled to such dividend, subdivision, split-up,
combination or distribution.

     (viii)  In the event the Company shall propose to take any action of the
types described in clauses (i), (ii), or (iii) of this Section 5, the Company
shall forward, at the same time and in the same manner, to the Holder of this
Warrant such notice, if any, which the Company shall give to the holders of
capital stock of the Company.

     (ix)  In any case in which the provisions of this Section 5 shall require
that an adjustment shall become effective immediately after a record date for an
event, the Company may defer until the occurrence of such event issuing to the
Holder of all or any part of this Warrant which is exercised after such record
date and before the occurrence of such event the additional shares of capital
stock issuable upon such exercise by reason of the adjustment required by such
event over and above the shares of capital stock issuable upon such exercise
before giving effect to such adjustment exercise; provided, however, that the
Company shall deliver to such Holder a due bill or other appropriate instrument
evidencing such Holder's right to receive such additional shares upon the
occurrence of the event requiring such adjustment.

SECTION 6.  OWNERSHIP.
            --------- 

     6.1.  OWNERSHIP OF THIS WARRANT.  The Company may deem and treat the person
           -------------------------                                            
in whose name this Warrant is registered as the holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by anyone
other than the Company) for all purposes and shall not be affected by any notice
to the contrary until presentation of this Warrant for registration of transfer
as provided in this Section 6.

     6.2.  TRANSFER AND REPLACEMENT.  This Warrant and all rights hereunder are
           ------------------------                                            
transferable in whole or in part (but not to more than three other holders) upon
the books of the Company by the Holder hereof in person or by duly authorized
attorney, and a new Warrant or Warrants, of the same tenor as this Warrant but
registered in the name of the transferee or transferees (and in the name of the
Holder, if a partial transfer is effected) shall be made and delivered by the
Company upon surrender of this Warrant duly endorsed, at the office of the
Company referred to in Section 12 hereof. Upon receipt by the Company of
evidence reasonably satisfactory to it of the loss, theft or destruction, and,
in such case, of indemnity or security reasonably satisfactory to it, and upon
surrender of this Warrant if mutilated, the Company will make and deliver a new
Warrant of like tenor, in lieu of this Warrant; provided that if the Holder
hereof is an instrumentality of a state or local government or an institutional
holder or a nominee for such an instrumentality or institutional holder an
irrevocable agreement of indemnity by such Holder shall be sufficient for all
purposes of this Section 6, and no evidence of loss or theft or destruction
shall be necessary. This Warrant shall be promptly cancelled by the Company upon
the surrender hereof in connection with any transfer or replacement. Stock
transfer taxes (if any) payable in connection with a transfer of this Warrant,
shall be payable by the Holder. Holder will not transfer this Warrant and the
rights hereunder except in compliance with federal and state securities laws.

its Common Stock, the Company shall mail notice thereof to the Holder hereof not

exercise of this Warrant but in any case where the Holder would, except for the
provisions of this Section 10, be entitled under the terms hereof to receive a
fractional share upon the complete exercise of this Warrant, the Company shall,
upon the exercise of this Warrant for the largest number of whole shares then
called for, pay a sum in cash equal to the excess of the value of such

good faith by the Board of Directors of the Company) over the Warrant Price for
such fractional share.

SECTION 11.  SPECIAL ARRANGEMENTS OF THE COMPANY.  The Company covenants and
             -----------------------------------
