promulgated under the Exchange Act. The aggregate purchase price of such shares,
together with the exercise price of such warrant is ten million one hundred
forty thousand dollars ($10,140,000). BankAmerica Ventures's capital available

event that BankAmerica Ventures chooses to so exercise.

        The MSDW Funds are the owner of ten thousand (10,000) shares of Series B

together with the exercise price of such warrant is ten million one hundred
thousand dollars ($10,100,000). The MSDW Funds' capital available for investment
was the source of the funds for the purchase of such shares and will be the
source of the funds needed for the exercise of such warrant in the event that
the MSDW Funds choose to so exercise.

ITEM 4. PURPOSE OF TRANSACTION.

        Bridge Financing. In an effort to raise additional capital, on May 21,
1999, the Company entered into a bridge loan with BankAmerica Ventures, the MSDW
Funds, and SWIB (the "Bridge Investors") for an aggregate amount of three
million dollars ($3,000,000), pursuant to the terms of that certain Securities
Purchase Agreement, dated May 20, 1999, and executed on May 21, 1999 (the
"Securities Purchase Agreement") filed as Exhibit 2 hereto (the "Bridge
Financing"). The Bridge Investors may increase the amount of the Bridge
Financing up to an aggregate of six million dollars ($6,000,000) at their
election. The Cardiac Pathways Corporation Senior Convertible Floating Rate
Bridge Notes (the "Notes"), filed as Exhibit 3 hereto, issued by the Company in
connection with the Bridge Financing are secured by substantially all of the
Company's assets pursuant to the terms of that certain Security Agreement, dated
May 20, 1999, and executed on May 21, 1999, filed as Exhibit 4 hereto, and
accrue interest at a floating rate per annum equal to the sum of the variable
rate of interest announced by Silicon Valley Bank as its "prime rate" in effect
from time to time, plus 2.00%. The Notes are convertible into shares of Series B
Preferred at the rate of $1,000 per share. On May 21, 1999, pursuant to the
terms of the Securities Purchase Agreement, the Company issued to each Bridge
Investor a warrant, the form of which is filed as Exhibit 5 hereto ("Warrant"),
to purchase a number of shares of Series B Preferred equal to the quotient of
(a) the aggregate amount of the Notes held by such Bridge Investor multiplied by
ten percent (10%) divided by (b) one thousand (1,000) (the "Warrant Coverage").
In the event that the Bridge Investors should choose to lend up to an additional
three million dollars ($3,000,000) to the Company, the Company shall issue to
the Bridge Investors the same Warrant Coverage on such additional funds, for an
aggregate Warrant Coverage of up to three hundred (300) shares of Series B
Preferred, convertible into an aggregate of sixty thousand (60,000) shares of
Common Stock.

        Purchase Agreement. On July 23, 1999, the Series B Investors purchased
thirty-two thousand (32,000) shares of Series B Preferred (convertible into six
million four hundred thousand (6,400,000) shares of Common Stock) for an
aggregate purchase price of thirty two million dollars ($32,000,000) (the
"Series B Financing") in accordance with the terms of the Securities Purchase
Agreement and that certain Series B Convertible Preferred Stock Purchase
Agreement, as amended, filed as Exhibit 6 hereto (the "Purchase Agreement"),
dated May 20, 1999, and executed on May 21, 1999 by and between the Company on
the one hand, and the Bridge

Investors, Van Wagoner Capital Management, Thomas Fogarty, and Trellis Health
Ventures L.P. on the other hand (collectively, the "Series B Investors"). In
connection with the Series B Financing, the Bridge Investors converted the Notes
and the interest accrued thereon into shares of Series B Preferred pursuant to
the terms of the Securities Purchase Agreement described above.

        The shares of Common Stock disclosed as beneficially owned by the Series
B Investors for the purpose of Rule 13d-5(b)(1) and Rule 13d-3 promulgated under
the Exchange Act consist of (i) thirty-two thousand (32,000) shares of Series B
Preferred purchased July 23, 1999, convertible into six million four hundred
thousand (6,400,000) shares of Common Stock, (ii) sixty thousand (60,000) shares
of Common Stock issuable upon conversion of Series B Preferred issuable upon
exercise of Warrants to purchase an aggregate of three hundred (300) shares of
Series B Preferred, and (iii) three hundred fifty-one thousand (351,000) shares
of Common Stock held by SWIB prior to the closing of the Series B Financing.

        Under the terms of the Purchase Agreement, the Company's existing board
of directors resigned effective upon the closing date of the Purchase Agreement.

        In May, 1999, Thomas M. Prescott was appointed as the Company's new
chief executive officer replacing William N. Starling, the Company's former
chief executive officer and president. Mr. Prescott was appointed at the
recommendation of the Series B Investors in accordance with the terms of the
Purchase Agreement.


        The Purchase Agreement provides that the holders of the Series B
Preferred shall have the right to nominate three (3) members of the Company's
board of directors, two (2) of whom shall be representatives of BankAmerica
Ventures who initially are Anchie Y. Kuo, M.D. and Mark J. Brooks and one (1) of
whom shall be a representative of Morgan Stanley Venture Partners III, L.P., who
initially is M. Fazle Husain. In the event that the number of the Company's
directors exceeds five (5), the holders of the Series B Preferred shall have the
right to nominate one (1) additional director. All members of the Company's
board of directors nominated by holders of the Series B Preferred shall have the
right to be members of all committees of the Company's board of directors. The
Company further agrees not to file any proxy or other materials with the
Securities and Exchange Commission opposed to the re-election of such persons as
directors of the Company unless such director has committed any action giving
the stockholders of the Company the right to remove such director for cause, and
to use all reasonable efforts to secure the election of such persons as
directors. The Purchase Agreement provides that the remaining directors of the
Company will include one (1) representative of the Company's management, who
shall be the Company's chief executive officer and one (1) outside
representative appointed by a majority of the Company's board of directors.

        As of May 21, 1999, under the terms of the Purchase Agreement, the
Company has agreed to grant to BankAmerica Ventures, Morgan Stanley Venture
Partners III, L.P. and SWIB, non-voting, board observation rights.

        Pursuant to the terms of the Purchase Agreement, in July 1999, the
Company obtained stockholder approval to amend its Certificate of Incorporation
to effect a one-for-five (1-for-5) reverse split of the outstanding Common Stock
and to amend its Bylaws to (i) fix the number of directors at five (5) members
with a provision that the number of directors may be increased to seven (7)
members with the consent of the directors who are representatives of the Series
B Investors, and (ii) to require the affirmative vote of the holders of at least
a majority of the voting power of all of the then outstanding shares entitled to
vote, voting together as a single class, to (I) increase the number of shares
reserved for issuance under the Company's stock plans, such that the quotient of
(A) the shares outstanding issued pursuant to the Company's stock plans plus the
shares available for issuance under the Company's stock plans plus additional
shares proposed to be issued under the Company's stock plans; divided by (B) the
total outstanding capital stock of the Company, including any outstanding
convertible preferred stock, on an as converted basis, is not greater than
thirty percent (30%);


                                    10 of 19

and (II) re-price any options granted after May 20, 1999 to purchase shares of
Common Stock under the Company's stock plans, provided that the Company shall
only re-price each option outstanding prior to May 20, 1999 once. In accordance
with the terms of the Purchase Agreement, the Company also obtained stockholder
approval to increase the number of shares of Common Stock available for
management and employees under the Company's 1991 Stock Option Plan by 4,000,000
shares.


        The Rights Preferences and Privileges of the Series B Preferred. The
Certificate of Designation filed by the Company with the Office of the Secretary

repurchase such shares at cost or at cost upon the occurrence of certain events,
such as the termination of employment; (vi) sell, convey, or otherwise dispose
of all or substantially all of its property or business or merge into or

organized, validly existing and in good standing under the laws of the State of
Delaware and is qualified to do business as a foreign corporation in each
jurisdiction where failure to qualify would not, individually or in the
aggregate, (i) adversely affect the legality, validity or enforceability of this

assets, prospects or financial condition of the Company, taken as a whole or

its obligations under this Agreement, the Voting Agreement or the Rights

                (b)     Authorization. The Company has full corporate power to
execute, deliver and perform this Agreement, the Voting Agreement and the Rights
Agreement, and each such agreement has been duly executed and delivered by the
Company and is the legal, valid and, assuming due execution by the Purchaser,
binding obligation of the Company, enforceable in accordance with its terms,
subject to applicable bankruptcy, insolvency, moratorium, reorganization or
similar laws affecting creditors' rights generally, and to general equitable
principles. The execution, delivery and performance by the Company of this
Agreement, the Voting Agreement and the Rights Agreement, including the issuance
(or reservation for issuance), sale and delivery of the Shares contemplated by
Section 1 hereof and the Common Stock issuable upon conversion thereof, have

Company, its officers, directors and stockholders; provided, however, that the
Company makes no representation or warranty as to the enforceability of the
indemnification and contribution provisions of Section 5 of the Rights Agreement
to the extent that the provisions thereof may be subject to limitations of
public policy and the effect of applicable statutes and judicial decisions. The
Board of Directors of the Company (at a meeting duly called and held) has (a)
determined that the sale of the Shares is advisable and fair and in the best
interests of the Company and its stockholders, and (b) recommended the approval
and adoption of this Agreement and approval of the sale of the Shares by the
stockholders and directed that this Agreement and the sale of the Shares by

Directors of the Company has taken all action necessary to render inapplicable,
as it relates to Purchasers, the provisions of Section 203 of the Delaware
General Corporation Law (the "DGCL"). No other corporate action on the part of
the Company is necessary to authorize the execution, delivery and performance of
this Agreement and the consummation of the transactions contemplated hereby
(other than, in the case of this Agreement, the approval of the sale of the
Shares by the holders of at least a majority of the Common Stock voting at the
meeting held to consider sale of the Shares).

                        (vi)    Multiemployer Plans. At no time has the Company
contributed to or been requested to contribute to any Multiemployer Plan.

                        (vii)   No Post-Employment Obligations. No Company
Employee Plan provides, or has any liability to provide, life insurance, medical
or other employee benefits to any Company Employee upon his or her retirement or
termination of employment for any reason, except as may be required by statute,
and the Company has never represented, promised or contracted (whether in oral
or written form) to any Company Employee (either individually or to Company
Employees as a group) that such Company Employee(s) would be provided with life
insurance, medical or other employee welfare benefits upon their retirement or
termination of employment, except to the extent required by statute.

                        (viii)  Effect of Transaction.

                                (1)     The execution of this Agreement and the
consummation of the transactions contemplated hereby will not (either alone or
upon the occurrence of any additional or subsequent events) constitute an event
under any Company Employee Plan, Company Employee Agreement, trust or loan that
will or may result in any payment (whether of severance pay or otherwise),
acceleration, forgiveness of indebtedness, vesting, distribution, increase in
benefits or obligation to fund benefits with respect to any Company Employee.

                        (ix)    Employment Matters. The Company and each of its
subsidiaries (i) is in compliance in all material respects with all applicable
foreign, federal, state and local laws, rules and regulations respecting
employment, employment practices, terms and conditions of employment and wages
and hours, in each case, in each location in which the Company or any of its
subsidiaries employs persons; (ii) has withheld all amounts required by law or
by agreement to be withheld from the wages, salaries and other payments to
Company Employees; (iii) is not liable for any material arrears of wages or any
material taxes or any material penalty for failure to comply with any of the
foregoing; and (iv) is not liable for any material payment to any trust or other
fund or to any governmental or administrative authority, with respect to
unemployment compensation benefits, social security or other benefits or
obligations for Company Employees (other than routine payments to be made in the
normal course of business and consistent with past practice).

                        (x)     Violations. To the Company's knowledge, no
employee of the Company has violated any employment contract, patent disclosure
agreement or non competition agreement between such employee and any former
employer of such employee due to such employee being employed by the Company and
disclosing to the Company trade secrets or proprietary information of such
employer. The Company is not, and has never been, a party to any collective
bargaining agreement. The Company and its subsidiaries are in compliance in all
material respects with all applicable laws regarding employment practices, terms
and conditions of employment, and wages and hours (including, without
limitation, ERISA, the Worker Adjustment and Retaining Notification Act or any
similar state or local law).

                (m)     Labor Matters. (i) There are no controversies pending
or, to the best knowledge of each of the Company and its respective
subsidiaries, threatened, between the




                                      -10-
<PAGE>   15

Company or any of its subsidiaries and any of their respective employees, which
controversies have or could reasonably be expected to have a Material Adverse
Effect; (ii) as of the date of this Agreement, neither the Company nor any of
its subsidiaries is a party to any collective bargaining agreement or other
labor union contract applicable to persons employed by the Company or its
subsidiaries nor does the Company or its subsidiaries know of any activities or
proceedings of any labor union to organize any such employees (A) as of the date
of this Agreement and (B) which, as of the Closing, have or could reasonably be
expected to have a Material Adverse Effect; and (iii) as of the date of this
Agreement, neither the Company nor any of its subsidiaries has any knowledge of
any strikes, slowdowns, work stoppages or lockouts, or threats thereof, by or
with respect to any employees of the Company or any of its subsidiaries (A) as
of the date of this Agreement and (B) which, as of the closing, have or could
reasonably be expected to have a Material Adverse Effect.

                (n)     Title to Property. The Company owns no material real
property. The Company and each of its subsidiaries have good and defensible
title to all of their material properties and assets, free and clear of all
liens, charges and encumbrances except liens for taxes not yet due and payable
and such liens or other imperfections of title, if any, as do not materially
detract from the value of or interfere with the present use of the property
affected thereby or which, individually or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect; and all leases
pursuant to which the Company or any of its subsidiaries lease from others
material amounts of real or personal property are in good standing, valid and
effective in accordance with their respective terms, and there is not, under any
of such leases, any existing material default or event of default (or any event
which with notice or lapse of time, or both, would constitute a material default
and in respect of which the Company or its subsidiary has not taken adequate
steps to prevent such default from occurring) except where the lack of such good
standing, validity and effectiveness or the existence of such default or event
of default could not, individually or in the aggregate, reasonably be expected
to have a Material Adverse Effect. All the plants, structures and equipment of
the Company and its subsidiaries, except such as may be under construction, are
in good operating condition and repair, except where the failure of such plants,
structures and equipment to be in such good operating condition and repair could
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

                (o)     Taxes. The Company and each of its subsidiaries, and any
consolidated, combined, unitary or aggregate group for tax purposes of which the
Company or any of its subsidiaries is or has been a member, have timely filed
all tax returns required to be filed by them and have paid all taxes shown
thereon to be due. These returns and reports are true and complete in all
material respects. The Company has paid all taxes and other assessments due. The
Company has provided adequate accruals in accordance with generally accepted
accounting principles in its financial statements for any taxes that have not
been paid, whether or not shown as being due on any tax returns. There is (i) no
material claim for taxes that is a lien against the property of the Company or
any of its subsidiaries or is being asserted against the Company or any of its
subsidiaries other than liens for taxes not yet due and payable, (ii) no audit
of any tax return of the Company or any of its subsidiaries being conducted by a
tax authority, (iii) no extension of the statute of limitations on the
assessment of any taxes granted by the Company or any of its subsidiaries and
currently in effect,



                                      -11-
<PAGE>   16

and (iv) no agreement, contract or arrangement to which the Company or any of
its subsidiaries is a party that may result in the payment of any amount that
would not be deductible by reason of Sections 162(m), 280G or 404 of the Code.
Neither the Company nor any of its subsidiaries has ever been a member of any
combined, controlled, consolidated or affiliated group (other than the group of
which the Company is the parent) for tax purposes. Neither the Company nor any
of its subsidiaries is a party to any tax sharing or tax allocation agreement
nor does the Company or any of its subsidiaries owe any amount under any such
agreement. Neither the Company nor any of its subsidiaries has been at any time,
a "United States real property holding corporation" with the meaning of Section
897(c)(2) of the Code.

                (p)     Compliance with Laws. Except with respect to
environmental matters (which are covered by Section 4(q) below), the Company and
its Subsidiaries are, and at all times since January 1, 1996 have been, in
compliance with all applicable laws, regulations, orders, judgments and decrees,
except where the failure to so comply would not have a Material Adverse Effect
on the condition of the Company and its Subsidiaries taken as a whole. Neither
the Company nor any of its subsidiaries has received any notice or other
communication from any governmental entity or other person regarding any actual
or possible material violation of, or material failure to comply with, any law,
regulation, order, judgment or decree.

                (q)     Environmental Matters.

the Comprehensive Environmental Response, Compensation, and Liability Act of
1980, as amended, or defined as a hazardous waste pursuant to the Resource
Conservation and Recovery Act of 1976, as amended, and the regulations
promulgated pursuant to Environmental Laws, but excluding office and janitorial
supplies maintained in accordance with Environmental Laws (a "HAZARDOUS

subsidiaries or any affiliate of the Company, or, to the Company's knowledge, as
a result of any action of any third party or otherwise, in, on or under any
property, including the land and the improvements, ground water and surface
water thereof, that the Company or any of its subsidiaries has at any time
owned, operated, occupied or leased. For the purposes of this Agreement,
"ENVIRONMENTAL LAWS" shall mean all federal, state, local and foreign laws,
ordinances, treaties, rules, regulations, guidelines and permit conditions
relating to contamination, pollution or the environment (including ambient air,
surface water, ground water, land surface or subsurface strata) or the
protection of human health and worker safety, including, without limitation,
laws and regulations relating to Hazardous Materials Activities (as hereinafter
defined) or emissions, discharges, releases or threatened releases of Hazardous
Materials.

                        (ii)    Hazardous Materials Activities. Neither the
Company nor any of its subsidiaries has (i) transported, stored, used,
manufactured, disposed of, released or exposed its



                                      -12-
<PAGE>   17

employees or others to Hazardous Materials in violation of Environmental Laws,
or (ii) disposed of, transported, sold, used, released, exposed its employees or
others to or manufactured any product contained a Hazardous Material
(collectively "HAZARDOUS MATERIALS ACTIVITIES") in violation of any
Environmental Laws in effect prior to or as of the date hereof except for which
violation has not heretofore been cured or for which there is any remaining
liability.

                        (iii)   Permits. The Company and its subsidiaries hold
all environmental approvals, permits, licenses, clearances and consents (the
"ENVIRONMENTAL PERMITS") necessary for the conduct of the Company's and its
subsidiaries' Hazardous Material Activities and other businesses of the Company
and its subsidiaries as such activities and businesses are currently being
conducted. The Company and its subsidiaries are and at all times have been in
compliance in all material respects with the terms of the Environmental Permits
except for which noncompliance has heretofore been cured or for which there is
any remaining liability.

                        (iv)    Environmental Liabilities. No action,
proceeding, revocation proceeding, amendment procedure, writ, claim or
injunction is pending, and to the Company's knowledge, no action, proceeding,
revocation proceeding, amendment procedure, writ, claim or injunction has been
threatened by any governmental entity against the Company or any of its
subsidiaries concerning any Environmental Permit, Hazardous Material or any
Hazardous Materials Activities of the Company or any of its subsidiaries.

                (r)     Intellectual Property. The Company or its subsidiaries

copyright applications, licenses, know-how and other similar rights and
proprietary knowledge (collectively with the patents and patent applications
described in the SEC Reports, the "INTANGIBLES") necessary for the conduct of
the Company's current, former and anticipated activities and (ii) neither the
Company nor any subsidiary, to its knowledge, has infringed, is infringing, or
has received any notice of infringement of any Intangible of any other person
that, if the subject of an unfavorable decision, ruling or finding, could
reasonably be expected to have a Material Adverse Effect and the Company knows
of no basis therefor. The expiration of any Intangibles would not have a
Material Adverse Effect on the Company and its subsidiaries taken as a whole.
Except as set forth in the SEC Reports, the Company has received no notice of
potential indemnity claims from customers based upon a notice of infringement
any such customer has received from a patent owner relating to an assertion of
infringement of a patent other than potential indemnity claims which
individually or in the aggregate would not reasonably be expected to have a
Material Adverse Effect on the Company.

                (s)     Personnel. All personnel, including employees, agents,
consultants and contractors, who have contributed to or participated in the
conception and development of the Intangibles on behalf of the Company have
executed nondisclosure agreements in the form set forth on the Disclosure

expected to have a Material Adverse Effect on the Company, all of the Company's
Information Technology (as defined below) effectively addresses the Year 2000

Company's business on or after January 1, 2000. For purposes of the foregoing,

firmware, telecommunications systems, network systems, embedded systems and
other systems, components and/or services that are owned or used by the Company
in the conduct of its business, or purchased by the Company from third party
suppliers.

                (u)     No Brokers. The Company has not directly or indirectly
employed any broker, finder or other person (including any employee) that might
be entitled to a fee, commission or other compensation upon the execution of
this Agreement, the Voting Agreement or the Rights Agreement or the consummation
of the transactions contemplated by this Agreement, the Voting Agreement or the
Rights Agreement for which the Purchasers or the Company is or may be liable.

                (v)     Chief Executive Officer. The Company has entered into an

                (w)     Registration Rights. Except as provided in the Rights
Agreement, the Company is presently not under any obligation and has not granted
any rights to register under the Securities Act any of its presently outstanding
securities or any of its securities that may subsequently be issued.

                (x)     Permits. The Company has all franchises, permits,
licenses, and any similar authority necessary for the conduct of its business as
now being conducted by it, the lack of which could have a Material Adverse
Effect on the business, properties, prospects, or financial condition of the
Company, and believes it can obtain, without undue burden or expense, any
similar authority for the conduct of its business as presently planned to be
conducted. The Company is not in default in any material respect under any such
franchises, permits, licenses or other similar authority.

                (y)     Royalties. Except as set forth in the Disclosure
Schedule, there are no royalties, fees, honoraria or other payments payable by
the Company to any person or entity by reason of the ownership, development,

business.

of Federal Regulations (the "FEDERAL REGULATIONS")), is a "small business
concern" within the meaning of the Small Business Investment Act of 1958, as
amended (the "SMALL BUSINESS ACT"), and Part 121 of Title 13 of the Federal
Regulations. The information delivered by the Company to Purchaser on SBA Forms
480, 652 and 1031 of the Small Business Administration (the "SBA") delivered in
connection herewith is accurate and complete. The Company is not ineligible for
financing by any SBIC Investor pursuant to Section 107.720 of Title 13 of the

of the transactions contemplated hereby.

                (ee)    Vote Required. The approval of the sale of the Shares by
the affirmative vote of a majority of the shares of Common Stock voting is the
only vote of the holders of any class or series of the Company's capital stock
necessary to approve the transactions contemplated hereby. Holders of Common
Stock will not have any appraisal rights or similar rights in connection with
the sale of the Shares or any of the other transactions contemplated hereby.

        5.      Representations and Warranties of the Purchasers. Each of the
Purchasers, severally and not jointly, hereby represents and warrants to the
Company as follows:

                (a)     Corporate Power. Each Purchaser is a corporation duly
incorporated or a limited partnership duly formed, validly existing and in good
standing under the laws of the jurisdiction of its incorporation or formation
with the requisite power and authority, corporate or otherwise, to enter into
and to consummate the transactions contemplated hereby and otherwise to carry
out its obligations hereunder and thereunder.

                (b)     Authorization. Each Purchaser has full power to execute,
deliver and perform this Agreement, the Voting Agreement and the Rights
Agreement, and each such agreement has been duly executed and delivered by such
Purchaser and is the legal, valid and, assuming due




                                      -15-
<PAGE>   20

execution by the Company, binding obligation of such Purchaser, enforceable in
accordance with its terms, subject to applicable bankruptcy, insolvency,
moratorium, reorganization or similar laws affecting creditors' rights
generally, and to general equitable principles. The execution, delivery and
performance by such Purchaser of this Agreement, the Voting Agreement and the
Rights Agreement, including the payment of the Purchase Price, have been duly
authorized by all necessary corporate action of such Purchaser.

                (c)     Governmental Approvals. No authorization, consent,
approval, license, exemption of or filing or registration with any court or
governmental department, commission, board, bureau, agency or instrumentality,
domestic or foreign, under any applicable laws, rules or regulations presently
in effect, other than a Control Certificate to be filed with the SBA by
BankAmerica Ventures within thirty (30) days of the Closing Date, is or will be
necessary to be made or obtained by such Purchaser or any of its Affiliates (as
such term is defined below) for, or in connection with, the execution and
delivery of this Agreement, the Voting Agreement or the Rights Agreement, the
consummation of the transactions contemplated hereby or thereby or performance
by such Purchaser of its obligations hereunder or thereunder. For purposes of
this Agreement, the term "AFFILIATE" means, when used with respect to any
specified person, any other person directly or indirectly controlling or
controlled by or under direct or indirect common control with such specified
person. For the purposes of this definition, "control," when used with respect
to any person, means the power to direct the management and policies of such
person, directly or indirectly, whether through the ownership of voting
securities, by contract or otherwise and the terms "affiliated," "controlling"
and "controlled" have meanings correlative to the foregoing.

                (d)     Non-Contravention. The execution, delivery and
performance by the Company of this Agreement, the Voting Agreement and the
Rights Agreement do not and will not (i) contravene or conflict with the charter
documents or bylaws of such Purchaser, or (ii) contravene or conflict with or
constitute a violation of any provision of any law, regulation, judgment,
injunction, order or decree binding upon or applicable to such Purchaser, or
result in a breach of or constitute a default under any material agreement of
such Purchaser.

                (e)     Risk Factors. Each such Purchaser acknowledges that an
investment in the Company involves known and unknown risks, uncertainties and
other factors which may result in such Purchaser's loss of its entire
investment. The Company is an early stage medical device company that develops
and intends to commercialize medical devices for the treatment of certain
cardiovascular and circulatory disorders. The Company's product candidates are
at an early stage of development and have not been approved for marketing by any
regulatory agencies. In addition, significant investment in research and
development, preclinical and clinical testing, regulatory and sales and
marketing activity will be necessary for the Company to commercialize its
product candidates. There can be no assurance that any of the Company's product
candidates can be successfully developed. If successfully developed, there can
be no assurance that the Company's product candidates will be approved for
marketing by regulatory agencies, will result in any meaningful benefits to
patients, will be accepted by the medical community for use in treatment or will
generate sufficient or sustainable revenues to enable the Company to be
profitable.




                                      -16-
<PAGE>   21

                        Each Purchaser acknowledges that such Purchaser has
received a copy of the SEC Reports and reviewed the section captioned "Factors
Affecting Future Operation Results" contained therein, which such factors are
deemed incorporated by reference into this Agreement.

                (f)     No Brokers. The Purchasers have not directly or
indirectly employed any broker, finder or other person (including any employee)
that might be entitled to a fee, commission or other compensation upon the
execution of this Agreement, the Voting Agreement or the Rights Agreement or the
consummation of the transactions contemplated by this Agreement, the Voting
Agreement or the Rights Agreement for which the Purchasers or the Company is or
may be liable.

        6.      Compliance with Securities Laws and Restrictions on Transfer of
Securities.

                (a)     Additional Representations and Warranties and Agreements
of Each Purchaser. Each Purchaser, severally and not jointly, hereby represents
and warrants to, and agrees with, the Company as follows:

                        (i)     The Purchaser (A) is purchasing the Shares for
its own account for investment only and not with a view to any resale or
distribution thereof, except pursuant to an effective registration statement
under the Securities Act of 1933, as amended from time to time (such act,
together with the rules and regulations promulgated thereunder, herein the
"Securities Act"), covering the sale, assignment or transfer or an opinion of
counsel reasonably satisfactory to the Company, concurred in by counsel to the
Company, that such registration is not required; provided, however, that
BankAmerica Ventures shall be permitted to transfer its Shares to Bank of
America Ventures, L.P. without such requirements.

                        (ii)    Such Purchaser has received and carefully
reviewed the Current SEC Filing, and has had the opportunity to obtain and
receive such other information as it deems necessary to understand the business
and financial condition of the Company and to make the investment decision to
purchase the Shares.

                        (iii)   As an investor in companies in the medical
device industry, such Purchaser has such knowledge and experience in financial
and business matters that it is capable of evaluating the merits and risks of
the investment represented by the Shares, and it is able to bear the economic
risk of such investment.

                        (iv)    Such Purchaser is an "accredited investor" as
such term is defined in Rule 501(a) of Regulation D under the Securities Act. If
other than an individual, the Purchaser also represents it has not been
organized for the purpose of acquiring the Shares.

                        (v)     Such Purchaser understands that the Shares are
being issued in a transaction which is exempt from the registration requirements
of the Securities Act by reason of the provisions of Section 4(2) of the
Securities Act and that the Shares will be subject to transfer restrictions and
must be held indefinitely unless subsequently registered under the Securities
Act or an exemption from such registration is available.




                                      -17-
<PAGE>   22

                        The certificate representing the Shares will be affixed
with the following legends:

                "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
                UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
                SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED, ASSIGNED OR
                OTHERWISE TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE
                REGISTRATION STATEMENT UNDER SAID ACT COVERING THE TRANSFER OR
                AN OPINION OF COUNSEL OR OTHER EVIDENCE IN FORM AND SUBSTANCE
                REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS
                NOT REQUIRED."

                        The restrictions on sale, assignment and transfer of the
Shares contained in this Section 6(a)(v) shall terminate at such time as there
shall be delivered to the Company and such Purchaser an opinion of counsel to
such Purchaser, in form and substance reasonably satisfactory to the Company, to
the effect that, due to the lapse of time or otherwise, no registration of such
securities is required under the Securities Act in connection with any
distribution of such securities to the public in the United States. In addition,
at any time after (A) the delivery of such opinion; or (B) such securities are
sold pursuant to and in accordance with an effective registration statement
under the Securities Act covering such sale, the Purchaser shall be entitled to
exchange its certificate representing such securities (or any portion thereof as
to which (A) or (B) above applies) for a new certificate not bearing the first
legend set forth in Section 6(a)(v).

                        (vi)    Such Purchaser understands that the Shares
constitute "restricted securities" within the meaning of Rule 144, promulgated
under the Securities Act. Purchaser is aware that Rule 144, in substance, except
as otherwise provided in subsection (k) of such rule, permits limited public
resale of "restricted securities" acquired, directly or indirectly, from the
issuer thereof (or from an affiliate of such issuer), in a non-public offering
subject to the satisfaction of certain conditions, including, among other
things: (A) the availability of certain public information about the Company;
(B) the resale occurring not earlier than the expiration of the applicable
holding period stated therein; (C) the sale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Exchange Act) and (D) the amount of
securities being sold during any three-month period not exceeding the specified
limitations stated therein. Such Purchaser also understands that the holding
period under Rule 144 will commence on the Closing Date.

                        (vii)   Such Purchaser further understands that in the
event all of the applicable requirements of Rule 144 are not satisfied,
registration under the Securities Act, compliance with Regulation A, or some
other registration exemption will be required; and that, notwithstanding the
fact that Rule 144 is not exclusive, the staff of the Commission has expressed
its opinion that persons proposing to sell private placement securities other
than in a registered offering and otherwise than pursuant to Rule 144 will have
a substantial burden of proof in establishing that




                                      -18-
<PAGE>   23

an exemption from registration is available for such offers or sales, and that
such persons and their respective brokers who participate in such transactions
do so at their own risk.

                (b)     Agreement Not to Transfer.

                        (i)     Prior to twelve months after the Closing, the
Purchasers shall not, directly or indirectly, Transfer or offer to Transfer any
Shares, unless the Company consents to such Transfer and the transferee agrees
to be bound by this Agreement; provided however, that BankAmerica Ventures shall
be permitted to transfer its Shares to Bank of America Ventures, L.P. without
such requirements.

                        (ii)    As used in this Section 6(b), the term
"TRANSFER" shall mean any sale, transfer, assignment, hypothecation, encumbrance
or other disposition, whether voluntary or involuntary, of Shares. In the case
of a hypothecation, the Transfer shall be deemed to occur both at the time of
the initial pledge and at any pledgee's sale or a sale by any secured creditor
or a retention by the secured creditor of the pledged Shares in complete or
partial satisfaction of the indebtedness for which the Shares are security.

                (c)     Stop Transfer Orders. Such Purchaser understands that
notations restricting the transfer of the Shares will be made on the transfer
records of the Company and that a stop transfer order will be entered with the
Company's transfer agent.

                (d)     Compliance with Section 6. None of the Shares (nor any
interest therein) shall be sold, assigned or offered except in accordance with
the provisions of this Section 6.

        7.      Additional Covenants of the Purchasers Regarding Securities.

                (a)     Forms 13D or 13G. Promptly following the Closing, the
Purchasers shall file with the Commission any reports regarding their ownership
of the Company's Common Stock as required by Section 13(d) of the Exchange Act
and the rules and regulations.

                (b)     Insider Trading Policy; Short Sales.

                        (i)     For so long as a representative of the
Purchasers is a member of the Board of Directors of the Company, the Purchasers
and their Affiliates who have access to Material Confidential Information (as
defined below) of the Company shall agree to comply with the Insider Trading
Compliance Program of the Company including, but not limited to, trade
pre-clearance requirements and trading blackout periods as may be in effect from
time to time. In addition, the Purchasers hereby acknowledge that each Purchaser
is aware, and that each Purchaser will advise such directors, officers,
employees, representatives, agents and advisors who are informed as to the
matters concerning the Company or who have access to the Company's Material
Confidential Information, that United States securities laws prohibit any person
who has received from an issuer material nonpublic information concerning the
issuer from communicating such information to any other person under
circumstances in which it is reasonably foreseeable that such person is likely
to purchase or sell the securities of such issuer, make investment
recommendations based on such




                                      -19-
<PAGE>   24

material nonpublic information or otherwise affect the trading price of such
issuer's securities. The limitations set forth in the immediately preceding
sentence are not intended to preclude the brokerage, investment advisory,
financial advisory, financing, money management, trading, arbitrage or other
similar activities conducted on the Purchasers' behalf by only those directors,
officers, representatives and agents and advisors who do not have access to the
Company's Material Confidential Information or are not aware of the content of
such Material Confidential Information.

                        (ii)    The Purchasers and their Affiliates shall not
make any short sale of, loan, or grant any option for the purchase of, any
equity securities of the Company held by the Purchasers at any time.

                (c)     Material Confidential Information.

                        (i)     In connection with the Purchasers'
decision-making with respect to their acquisition of the Shares, the Company has
furnished to the Purchasers and their officers, directors, employees and agents
(collectively referred to as "PURCHASERS AND AGENTS") financial and other
information which has not theretofore been made available to the public
("MATERIAL CONFIDENTIAL INFORMATION"). The Purchasers and Agents may also
receive Material Confidential Information of the Company in the future. Pursuant
to a Nondisclosure Agreement dated March 5, 1999, the Purchasers have agreed to
refrain from disclosing such information pursuant to the terms and conditions of
such agreement. The Company and the Purchasers wish to replace the
confidentiality obligations of the parties set forth in such agreement with
those provided herein. Therefore, the Purchasers and Agents shall treat all such
Material Confidential Information in accordance with the provisions of this
agreement and to take or abstain from taking certain other actions herein set
forth. The term "Material Confidential Information" does not include information
which (i) was already in the Purchasers' or Agents' possession prior to the
disclosure by the Company of the Material Confidential Information, provided
that such information is not known by the Purchasers and Agents to be subject to
another confidentiality agreement with or other obligation of secrecy to the
Company or another party, (ii) becomes generally available to the public other
than as a result of disclosure by the Purchasers or Agents or (iii) becomes
available to you on a non-confidential basis from a source other than the
Company or its advisors, provided that such source is not known to the
Purchasers or Agents to be bound by a confidentiality agreement with or other
obligation of secrecy to the Company or another party. The Purchasers agree that
the Company's Material Confidential Information will be used solely for the
purpose of monitoring the Purchasers' holdings of the Shares. The Purchasers
also agree that the Purchasers and Agents will not disclose any of the Company's
Material Confidential Information now or hereafter received or obtained from the
Company or its representatives to any third party or otherwise use or permit the
use of the Material Confidential Information, except as required by applicable
law or legal process, without the prior written consent of the Company;
provided, however, that any such Material Confidential Information of the
Company may be disclosed to such of the Purchasers' representatives who need to
know such information for the purpose of monitoring the Purchasers' investment
in the Shares; in which case it is understood that the Purchasers'
representatives, directors, officers, employees, agents and advisors shall be
informed by the Purchasers of the confidential nature of such information and
shall be directed by the Purchasers to treat such information confidentially. In
the




                                      -20-
<PAGE>   25

event that the Purchasers and Agents or any of their representatives becomes
legally compelled (by deposition, interrogatory, request for documents,
subpoena, civil investigative demand, other demand or rules and regulations
under the federal securities laws or similar process, but not pursuant to laws
and regulations which Purchasers and Agents are subject to as a result of being
an affiliate of a national bank) to disclose any of the Material Confidential
Information, the Purchasers and Agents shall provide the Company with prompt
prior written notice of such requirement prior to such disclosure. In the event
that a protective order or other remedy is not obtained, or that the Company
waives compliance with the provisions hereof, each Purchaser agrees to furnish
only that portion of the Material Confidential Information which such Purchaser
is legally required to furnish and, where appropriate, to exercise the
Purchasers' and Agents' reasonable efforts to obtain assurances that
confidential treatment will be accorded such Material Confidential Information.

                (d)     Reporting Obligations Pursuant to Section 16. The
Purchasers agree to file with the Commission any reports required to be filed
pursuant to Section 16(a) of the Exchange Act and the rules and regulations
promulgated thereunder by such Purchasers, their officers, directors, employees
or affiliates or by such Purchasers' nominee to the Company's Board of Directors
within the time such filings are required to be made and to provide the Company
with a copy of all such filings promptly thereafter.

        8.      Additional Covenants of the Company.

                (a)     Inspection. For so long as a Purchaser holds at least
500 shares of Series B Convertible Preferred Stock (or the Common Stock issuable
or issued upon conversion of 500 shares of Series B Convertible Preferred
Stock), the Company shall permit each the Purchaser, at such Purchaser's
expense, to visit and inspect the Company's properties, to examine its books of
account and records and to discuss the Company's affairs, finances and accounts
with its officers, all at such reasonable times as may be requested by the
Investor; provided, however, that the Company shall not be obligated pursuant to
this Section 8(a) to provide access to any information that it reasonably
considers to be a competitively sensitive information unless such Purchaser has
executed a non-disclosure agreement in a form reasonably acceptable to the
Company.

                (b)     Board of Directors. The following actions will be taken
with respect to the Company's Board of Directors.

                        (i)     The existing Board of Directors will resign
effective as of the Closing Date.

                        (ii)    At or prior to the Closing the Company shall
amend its Bylaws, if required, to fix the number of directors to five (5)
members with a provision that the number of directors may be increased to seven
(7) members with the consent of the directors who are representatives of the
Purchasers.

                        (iii)   The holders of the Series B Convertible
Preferred shall have the right to nominate three (3) members of the Company's
Board of Directors, two (2) of which shall be representatives of BankAmerica
Ventures and one (1) of which shall be a representative of Morgan




                                      -21-
<PAGE>   26

Stanley Dean Witter Venture Partners ("MSDW"). In the event that the number of
the Company's directors exceeds five (5), the holders of Series B Convertible
Preferred shall have the right to nominate one (1) additional director. All
members of the Company's Board of Directors nominated by holders of Series B
Convertible Preferred shall have the right to be members of all committees of
the Board of Directors. The Company shall not file any proxy or other materials
with the SEC opposed to the re-election of such persons as directors of the
Company unless such director has committed any actions giving the stockholders
of the Company the right to remove such director for cause and shall use all
reasonable efforts to secure the election of such persons as directors.

                        (iv)    The remaining directors will include (i) one (1)
representative of the Company's management, who shall be the Company's Chief
Executive Officer and (ii) one (1) outside representative appointed by a
majority of the Board of Directors.

                        (v)     As of the execution of this Agreement and in the
event that BankAmerica Ventures, the State of Wisconsin Investment Board
("SWIB") or MSDW do not have a representative on the Company's Board of
Directors, or any committee thereof then the Company shall invite a
representative of BankAmerica Ventures, SWIB or MSDW, as the case may be, to
attend all meetings of its Board of Directors or any committee thereof in a
nonvoting observer capacity and, in this respect, shall give such representative
copies of all notices, minutes, consents, and other materials (the "BOARD
MATERIALS") that it provides to its directors at the same time as such Board
Materials are provided to any of its directors; provided, however, that the
Company reserves the right to withhold any information and to exclude such
representative of BankAmerica Ventures, SWIB or MSDW from any meeting or portion
thereof if the disclosure of such material or discussion, in the opinion of
counsel to the Company, would jeopardize the Company's attorney client
privilege. The right granted to BankAmerica Ventures, SWIB and MSDW to attend
meetings of the Company's Board of Directors and to receive Board Materials
shall not be assignable.

                (c)     Right of First Offer. Subject to the terms and
conditions specified in this Section 8(c), the Company hereby grants to each
Purchaser a right of first offer to purchase its Pro Rata Share (as hereinafter
defined) (in whole or in part) with respect to future sales by the Company of
its Future Shares (as hereinafter defined). Each Purchaser shall be entitled to
assign or apportion the right of first offer hereby granted it among itself and
its partners and affiliates (including in the case of a venture capital fund
other venture capital funds affiliated with such fund) in such proportions as it
deems appropriate. For purposes of this Section 8(c), a Purchaser's "PRO RATA
SHARE" of Future Shares shall mean that number of Future Shares that equals the
proportion that (x) the number of shares of Common Stock issued and held, or
issuable upon conversion of the Shares then held, by such Purchaser bears to (y)
the total number of shares of Common Stock of the Company then outstanding
(assuming full conversion of all convertible securities).

                        (i)     Each time the Company proposes to offer any
shares of, or securities convertible into or exercisable for any shares of, any
class of its capital stock, including any debt securities convertible into
equity (collectively, "FUTURE SHARES"), the Company shall first make an offering
of such Future Shares to each Purchaser in accordance with the following
provisions:




                                      -22-
<PAGE>   27

                        (ii)    The Company shall deliver a notice by confirmed
facsimile transmission, certified mail or a nationally recognized overnight
courier service ("NOTICE") to each of the Purchasers stating (i) its bona fide
intention to offer such Future Shares, (ii) the number of such Future Shares to
be offered, and (iii) the price and a summary of the terms, if any, upon which
it proposes to offer such Future Shares.

                        (iii)   By written notification to the Company within
ten (10) calendar days after receipt of the Notice, each Purchaser may elect to
purchase or obtain, at the price and on the terms specified in the Notice, up to
its Pro Rata Share of such Future Shares. The Company shall promptly, in
writing, inform each Purchaser that elects to purchase all the shares available
to it (a "FULLY-EXERCISING PURCHASER") of any other Purchaser's failure to do
likewise. During the ten (10) day period commencing after such information is
given, each Fully-Exercising Purchaser may elect to purchase that portion of the
Future Shares for which Purchasers were entitled to subscribe but that were not
subscribed for by the Purchasers that is equal to the proportion that the number
of shares of Common Stock issued and held, or issuable upon conversion of Shares
then held, by such Fully-Exercising Purchaser bears to the total number of
shares of Common Stock issued and held, or issuable upon conversion of the
Shares then held, by all Fully-Exercising Purchasers who wish to purchase some
of the unsubscribed Future Shares.

                        (iv)    If all Future Shares that the Purchasers are
entitled to obtain pursuant to Section 8(c) are not elected to be obtained as
provided herein, the Company may, during the sixty (60) day period following the
expiration of the period provided in Section 8(c)(iii) hereof, offer the
remaining unsubscribed portion of such Future Shares to any person or persons at
a price not less than, and upon terms no more favorable to the offeree than
those specified in the Notice. If the Company does not enter into an agreement
for the sale of the Future Shares within such period, or if such agreement is
not consummated within sixty (60) days of the execution thereof, the right
provided hereunder shall be deemed to be revived and such Future Shares shall
not be offered unless first reoffered to the Purchasers in accordance herewith.

                        (v)     The right of first offer in this Section 8(c)
shall not be applicable (i) to any shares of Common Stock (including shares
issued upon exercise of stock options outstanding as of the date of this
Agreement) issuable or issued to employees, consultants or directors directly or
pursuant to stock option plans or arrangements approved by the Board of
Directors, including each board representative of the Purchasers, (ii) to shares
of Common Stock issued or issuable in a firm commitment underwritten public
offering, (iii) to shares of Common Stock issued or issuable upon conversion of
shares of Series A Participating Preferred Stock or Series B Convertible
Preferred Stock or as a dividend or distribution on the shares of Series A
Participating Preferred Stock or Series B Convertible Preferred Stock, (iv) to
securities issued or issuable to banks or equipment lessors, provided such
issuances are for other than primarily equity financing purposes and provided
such issuances are approved by the Board of Directors, including each board
representative of the Purchasers, (v) to securities issued in connection with
business combinations or corporate partnering agreements approved by the Board
of Directors, including each board representative of the Purchasers, or (vi) to
securities issued in strategic financings accompanies by commercial

Directors, including each board representative of the Purchasers.

                        (vi)    The rights granted to the Purchasers under
Section 8(c) hereof may be assigned to any transferee or assignee who is (a) a
subsidiary, parent, general partner, limited partner, retired partner, member or
retired member of a Purchaser, (b) a Purchaser's ancestors, descendants or
spouse or to trusts for the benefit of such persons or such Purchaser or (c) a
client, employee or member of a Purchaser, provided that (i) such transfer may
otherwise be effected in accordance with applicable securities laws, (ii) the
Company is given written notice of any such transfer five (5) Business Days
prior to the date of said transfer, stating the name and address of said
transferee or assignee and identifying the securities with respect to which such
registration rights are being assigned and (iii) the transferee or assignee of
such rights is not deemed by the Board of Directors of the Company, in its
reasonable judgment, to be a competitor of the Company and provided further that
the transferee or assignee of such rights assumes in writing in a form
reasonably acceptable to the Company the obligations of the Purchasers under
this Agreement.

                (d)     Sonometrics License. The Company will use its best
efforts to execute an agreement to exclusively license or acquire, for an
aggregate purchase price no greater than $1,500,000, Sonometric's patent

use it best efforts to retain such Chief Executive Officer through the Closing
Date.

                (f)     Reverse Stock Split; Bylaws. The Company shall use its
best efforts to obtain stockholder approval to amend (i) the Certificate of
Incorporation to effect a five for one reverse stock split of the Company's
Common Stock; and (ii) the Bylaws to require the affirmative vote of the holders
of at least a majority of the voting power of all of the then outstanding shares
entitled to vote, voting together as a single class, to (I) increase the number
of shares reserved for issuance under the Company's Stock Plans, such that the
quotient of (A) the shares outstanding issued pursuant to the Company's Stock
Plans plus the shares available for issuance under the Company's Stock Plans
plus additional shares proposed to be issued under the Company's Stock Plans;
divided by (B) the total outstanding capital stock of the Company, including any
outstanding convertible preferred stock, on an as converted basis, is not

corporate purposes. The Company will provide to each Purchaser identified as a
licensed Small Business Investment Company on Schedule A hereto (each an "SBIC
INVESTOR"), and to the Small Business Administration (the "SBA"), reasonable
access to the Company's books and records for the purpose of confirming the use
of proceeds by the Company.

                        (ii)    For a period of one (1) year following the

                        (iii)   So long as any SBIC Investor holds any

provided (or incorporated by reference to filings made with the Commission by
the Company) in the Proxy Statement, on the date the Proxy Statement is filed
with the Commission and on the date it is first mailed to the Company's
stockholders, shall not contain any untrue statement of a material fact or omit

with respect to the sale of Shares under the Securities Act and the Exchange Act
and the rules and regulations thereunder and under applicable blue sky or
similar laws and shall use their reasonable efforts to obtain required approvals
and clearances with respect thereto.

                (m)     Stockholder Approvals; Recommendations. The Company,
acting through its Board of Directors, shall (i) call, give notice of, convene
and hold a special meeting of the holders of Company Common Stock for the
purpose of voting upon the sale of the Shares (the "SPECIAL MEETING") and (ii)

together will constitute one and the same instrument.

                (g)     Entire Agreement. This Agreement, the Voting Agreement
and the Rights Agreement, together with the Exhibits and other documents
attached hereto and thereto, constitute the entire contract between the parties
with respect to the subject matter hereof and thereof, and no party will be
liable or bound to the other in any manner by any representations, warranties or
covenants except as specifically set forth herein and therein.

                (h)     Titles. The titles of the Sections of this Agreement are
inserted for reference only, and are not to be considered as part of this
Agreement in construing this Agreement.

                (i)     Termination. This Agreement may be terminated and the
transactions contemplated hereby may be abandoned, at any time prior to the
Closing, whether before or after approval of the sale of Shares by the
stockholders of the Company:

                (i)     by mutual consent of the Company and of a majority in
interest of Purchasers as set forth on Schedule A;

                        (ii)    by either a majority in interest of Purchasers
as set forth on Schedule A or the Company, if the Closing shall not have
occurred by October 31, 1999 (unless the failure to consummate the sale of
Shares is attributable to a failure on the part of the party seeking to
terminate this Agreement to perform any material obligation required to be
performed by such party at or prior to the Closing);

                        (iii)   by a majority in interest of Purchasers as set
forth on Schedule A, if the required approval of the Company's stockholders
shall not have been obtained by reason of the failure to obtain the required
vote at a duly held meeting of stockholders or at any adjournment thereof;

                        (iv)    by either a majority in interest of Purchasers
as set forth on Schedule A or the Company, if there shall be any law or
regulation of any Governmental Entity that makes consummation of the purchase of
the Shares illegal or otherwise prohibited or if any judgment, injunction, order
or decree of any governmental entity prohibiting such transaction is entered and
such judgment, injunction, order or decree shall have become final and
nonappealable;

                        (v)     by a majority in interest of Purchasers as set
forth on Schedule A, if there has been a breach of any covenant or a breach of
any representation or warranty on the part of the Company, such that the closing
conditions set forth in Section 9 would not be satisfied or if the Company has
not secured interim financing as specified in Section 9(xvi) by May 21, 1999.

                (j)     Effect of Termination. In the event of the termination
of this Agreement pursuant to Section 10(i) hereof by the Company, or a majority
in interest of Purchasers, written notice thereof shall forthwith be given to
the other party or parties specifying the provision hereof pursuant to which
such termination is made, and this Agreement shall become void and have no
effect, and there shall be no liability hereunder on the part of Purchasers.
Nothing in this Section 10(j) shall relieve any party to this Agreement of
liability for breach of this Agreement or for representations which were
incorrect when made.
