ITEM 5. OTHER EVENTS.

      On August 19, 1999, CyberCash, Inc. (the "Company") issued and sold
pursuant to a shelf takedown under the Company's Registration Statement on Form
S-3 (SEC File No. 333-79943) an aggregate of 1,643,836 shares of the Company's
common stock, par value $.001 per share, and warrants to purchase 164,384
shares of common stock. The purchase price for the common stock was $9.125 per
share and the exercise price for the warrants is initially equal to $11.40622
per share. A prospectus supplement was filed in connection with the transaction
on August 19, 1999 under Securities Act Rule 424(b).

      The Company reserved additional shares of common stock to be issued in
the event that the average of the closing bid prices of the common stock as
reported on Nasdaq for the ten consecutive trading days immediately preceding
August 19, 2000 (the "One-Year Price") is less than $9.125 per share.  In that
event, the Company is obligated to issue a number of additional shares equal to
the difference between $9.125 and the One-Year Price and to reduce the exercise
price of the warrants.

                          SECURITIES PURCHASE AGREEMENT

       SECURITIES PURCHASE AGREEMENT (this "AGREEMENT"), dated as of August 19,
1999, by and among CyberCash, Inc., a Delaware corporation, with headquarters
located at 2100 Reston Parkway, 3rd Floor, Reston, Virginia 20191 ("COMPANY"),
and each of the purchasers set forth on the signature pages hereto (the
"BUYERS").

       WHEREAS:

                     A.     The Company has authorized the issuance to the
Buyers of an aggregate of $15,000,000 of the Company's common stock, par value
$.001 per share (the "COMMON STOCK"), and warrants in the form attached hereto
as EXHIBIT "A" (each a "WARRANT" and, collectively, the "WARRANTS") to purchase
an aggregate of $1,875,000 of Common Stock. The shares of Common Stock issuable
pursuant hereto, together with any shares of Common Stock issued in replacement
thereof or as a dividend thereon or otherwise with respect thereto, are
hereinafter referred to as the "COMMON SHARES." The shares of Common Stock
issuable upon exercise of or otherwise pursuant to the Warrants are hereinafter
collectively referred to as the "WARRANT SHARES." The Common Shares, the
Warrants and the Warrant Shares (together with the Additional Shares, the
Additional Warrants and the shares of Common Stock issuable upon exercise of the
Additional Warrants (as each such term is defined in Section 1(a) below)) are
sometimes hereinafter collectively referred to as the "SECURITIES. "

                     B.     The Buyers desire to purchase and the Company
desires to issue and sell, upon the terms and conditions set forth in this
Agreement, the Common Shares and the Warrants for an aggregate purchase price of
Fifteen Million Dollars ($15,000,000).

                     C.     The issuance of the Common Shares, the Warrants and
the Warrant Shares have been registered on the Company's Registration Statement
on Form S-3, Registration No. 333-79943, which was declared effective by the
Securities and Exchange Commission on June 18, 1999 (the "REGISTRATION
STATEMENT").

       NOW, THEREFORE, the Company and each of the Buyers severally (and not
jointly) hereby agree as follows:

              1.     PURCHASE AND SALE OF SECURITIES.

                     (a)    PURCHASE OF SECURITIES; ADDITIONAL SHARES.

                            (i)    The Company shall issue and sell to each
Buyer and each Buyer severally agrees to purchase from the Company the dollar
amount of Common Shares and Warrants set forth immediately below such Buyer's
name on the signature pages hereto. The number of Common Shares issuable by the
Company to each Buyer on the Closing Date (as defined below) will equal the
quotient arrived at by dividing (x) the Purchase Price (as defined below) to be
paid by such Buyer, by (y) the average of the closing bid prices of the Common


<PAGE>   2


Stock as reported on the Nasdaq National Market ("NASDAQ") during the three (3)
consecutive trading day period ending on the trading date immediately preceding
the Closing Date (the "CLOSING Price"). On the Closing Date, the Buyers will
also receive Warrants to purchase an aggregate number of Warrant Shares
initially equal to ten (10%) percent of the number of Common Shares purchased by
the Buyers at the Closing for an exercise price per share equal to 125% of the
Closing Price (the "EXERCISE PRICE"). The number of Warrant Shares and the
Exercise Price will be subject to adjustment as provided in the Warrants.

                            (ii)   In the event that the average of the closing
bid prices of the Common Stock as reported on Nasdaq for the ten (10)
consecutive trading days immediately preceding the one-year anniversary of the
Closing Date (as defined below) (the "ONE YEAR PRICE") is less than the Closing
Price, the Company shall, within three (3) business days of the one-year
anniversary of the Closing Date, be required to either: (i) deliver to each
Buyer additional shares of Common Stock (the "ADDITIONAL SHARES") in an amount
such that the total number of shares of Common Stock issued to such Buyer (i.e.,
the Common Shares issued on the Closing Date plus the Additional Shares) equals
(x) the Purchase Price paid by such Buyer on the Closing Date, divided by (y)
the One Year Price; or (ii) pay to each Buyer in cash an amount equal to (x) the
number of Additional Shares issuable to such Buyer pursuant to the preceding
clause (i), multiplied by (y) the One Year Price; provided, however, that the
Company may only elect to issue the Additional Shares in lieu of paying cash to
any such Buyer if (and to the extent that) such issuance is then registered
pursuant to the Registration Statement and such Registration Statement is
effective. In the event that the Company is unable to issue the Additional
Shares due to the failure of the condition set forth in the preceding proviso,
the Company will pay to each of the Buyers the amount specified in clause (ii)
of the preceding sentence.

                            (iii)  Notwithstanding the provisions of Section
1(a)(ii) above, in the event that the Company elects to issue Additional Shares
to any Buyer (in lieu of paying cash) pursuant to Section 1(a)(ii) above and
such Buyer determines that such issuance would result in the beneficial
ownership by such Buyer and its affiliates of more than 9.9% of the then
outstanding shares of Common Stock (as determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended (the "1934 ACT"), and
Schedule 13D-G thereunder), such Buyer may, in lieu of receiving such Additional
Shares, elect instead to receive warrants (the "ADDITIONAL WARRANTS") to
purchase a like amount of shares of Common Stock at an exercise price of $.01
per share. The Additional Warrants will be in substantially the same form as
EXHIBIT "B". In the event that any such election is made by any Buyer, the
Company agrees to register the issuance of the Additional Warrants and the
shares of Common Stock issuable upon the exercise thereof pursuant to the
Registration Statement or a subsequently filed registration statement.

                            (iv)   Each Buyer agrees that, upon issuance of the
Additional Shares, the Additional Warrants or shares of Common Stock underlying
the Additional Warrants pursuant to paragraphs (ii) or (iii) above, such Buyer
shall be deemed to have waived any anti-dilution provisions contained in (i)
Section 4(a) of the Investment Options dated February 5, 1998 and July 13, 1998,
respectively, and (ii) Section 5(a) of the Warrants, that may be triggered by
the issuance or exercise of the Additional Shares or Additional Warrants, as
applicable.


<PAGE>   3


                     (b)    FORM OF PAYMENT. On the Closing Date (as defined
below), (i) each Buyer shall pay the purchase price for the Common Shares and
the Warrants to be issued and sold to it at the Closing (as defined below) (the
"PURCHASE PRICE") by wire transfer of immediately available funds to the
Company, in accordance with the Company's written wiring instructions, against
delivery of the Common Shares and Warrants which such Buyer is purchasing and
(ii) the Company shall deliver such Common Shares and the Warrants on behalf of
the Company, to such Buyer, against delivery of such Purchase Price.

                     (c)    CLOSING DATE. Subject to the satisfaction (or
waiver) of the conditions thereto set forth in Section 6 and Section 7 below,
the date and time of the issuance and sale of the Securities pursuant to this
Agreement (the "CLOSING") shall be, 9:00 a.m. Eastern Standard Time on August
19, 1999, or such other mutually agreed upon time (the "CLOSING DATE"). The
Closing shall occur on the Closing Date at the offices of Hogan & Hartson,
L.L.P., Baltimore, Maryland, or at such other location as may be agreed to by
the parties.

              2.     BUYERS' REPRESENTATIONS AND WARRANTIES. Each Buyer
severally (and not jointly) represents and warrants to the Company solely as to
such Buyer that:

                     (a)    INFORMATION. The Buyer and its advisors, if any,
have been furnished with all materials relating to the business, finances and
operations of the Company and materials relating to the offer and sale of the
Securities which have been requested by the Buyer or its advisors. The Buyer and
its advisors, if any, have been afforded the opportunity to ask questions of the
Company. Neither such inquiries nor any other due diligence investigation
conducted by Buyer or any of its advisors or representatives shall modify, amend
or affect Buyer's right to rely on the Company's representations and warranties
contained in Section 3 below.

                     (b)    AUTHORIZATION; ENFORCEMENT. This Agreement has been
duly and validly authorized, has been duly executed and delivered on behalf of
the Buyer, and constitutes a valid and binding agreement of the Buyer
enforceable in accordance with its terms.

                     (c)    BUYER STATUS. The Buyer is an institutional investor
who is purchasing the Securities in the ordinary course of its business and has
no arrangement with any person to participate in the distribution of the
Securities.

                     (d)    STOCK OWNERSHIP. The Buyer does not own any Common
Stock or securities convertible or exercisable into Common Stock, other than (i)
securities issued or issuable pursuant to that certain Securities Purchase
Agreement dated as of January 6, 1999 and (ii) Investment Options issued
pursuant to that certain Securities Purchase Agreement dated February 5, 1998.

              3.     REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
represents and warrants to each Buyer that:

                     (a)    ORGANIZATION AND QUALIFICATION. The Company and each
of its Subsidiaries (as defined below), if any, is a corporation duly organized,
validly existing and in good standing under the laws of the jurisdiction in
which it is incorporated, with full power and


<PAGE>   4


authority (corporate and other) to own, lease, use and operate its properties
and to carry on its business as and where now owned, leased, used, operated and
conducted. SCHEDULE 3(a) sets forth a list of all of the Subsidiaries of the
Company and the jurisdiction in which each is incorporated. The Company and each
of its Subsidiaries is duly qualified as a foreign corporation to do business
and is in good standing in every jurisdiction in which its ownership or use of
property or the nature of the business conducted by it makes such qualification
necessary except where the failure to be so qualified or in good standing would
not have a Material Adverse Effect. "MATERIAL ADVERSE EFFECT" means any material
adverse effect on (i) the Securities, (ii) the business, operations, assets,
financial condition or prospects of the Company and its Subsidiaries, if any,
taken as a whole, or (iii) on the transactions contemplated hereby or by the
agreements or instruments to be entered into in connection herewith.
"SUBSIDIARIES " means any corporation or other organization, whether
incorporated or unincorporated, in which the Company owns, directly or
indirectly, any equity or other ownership interest and in which such ownership
interest entitles the Company to elect a majority of the Board of Directors or
similar governing body.

                     (b)    AUTHORIZATION; ENFORCEMENT. (i) The Company has all
requisite corporate power and authority to enter into and perform this Agreement
and the Warrants (and the Additional Warrants) and to consummate the
transactions contemplated hereby and thereby and to issue the Securities, in
accordance with the terms hereof and thereof, (ii) the execution and delivery of
this Agreement and the Warrants (and the Additional Warrants) by the Company and
the consummation by it of the transactions contemplated hereby and thereby
(including without limitation, the issuance of the Common Shares and the
Warrants and the issuance and reservation for issuance of the Warrant Shares,
the Additional Shares and the shares of Common Stock underlying the Additional
Warrants) have been duly authorized by the Company's Board of Directors and no
further consent or authorization of the Company, its Board of Directors, or its
stockholders is required (except as contemplated hereby), (iii) this Agreement
has been duly executed and delivered by the Company, and (iv) this Agreement
constitutes, and upon execution and delivery by the Company of the Warrants (and
the Additional Warrants), such instruments will constitute, a legal, valid and
binding obligation of the Company enforceable against the Company in accordance
with its terms.

                     (c)    CAPITALIZATION. As of the date hereof, the
authorized capital stock of the Company consists of (i) 40,000,000 shares of
Common Stock of which 21,433,753 shares are issued and outstanding, 3,774,465
shares are reserved for issuance pursuant to outstanding options and commitments
under the Company's stock option plans, 4,330,334 shares are reserved for
issuance pursuant to securities (other than the Warrants, the Additional Shares,
the Additional Warrants and the aforementioned shares reserved for issuance
pursuant to the Company's stock option plans) exercisable for, or convertible
into or exchangeable for shares of Common Stock, and 328,768 (2x currently
required) shares are reserved for issuance upon exercise of the Warrants and in
connection with the Company's obligation to issue Additional Shares and/or
Additional Warrants (subject to adjustment pursuant to the Company's covenant
set forth in Section 4(h) below); and (ii) 5,000,000 shares of preferred stock,
none of which is issued or outstanding, and of which 300,000 are designated as
Series E Junior Participating Preferred Stock, none of which is issued or
outstanding. All of such outstanding shares of capital stock are, or upon
issuance will be, duly authorized, validly issued, fully paid and nonassessable.
No shares of capital stock of the Company are subject to preemptive rights or
any other similar rights of the stockholders of the


<PAGE>   5


Company or any liens or encumbrances imposed through the actions or failure to
act of the Company. Except as disclosed in SCHEDULE 3(c), as of the date of this
Agreement, (i) there are no outstanding options, warrants, scrip, rights to
subscribe for, puts, calls, rights of first refusal, agreements, understandings,
claims or other commitments or rights of any character whatsoever relating to,
or securities or rights convertible into or exchangeable for any shares of
capital stock of the Company or any of its Subsidiaries, or arrangements by
which the Company or any of its Subsidiaries is or may become bound to issue
additional shares of capital stock of the Company or any of its Subsidiaries,
(ii) there are no agreements or arrangements under which the Company or any of
its Subsidiaries is obligated to register the sale of any of its or their
securities under the Securities Act of 1933, as amended (the "1933 ACT"), and
(iii) there are no anti-dilution or price adjustment provisions contained in any
security issued by the Company (or in any agreement providing rights to security
holders) that will be triggered by the issuance of the Common Shares, the
Warrants, the Warrant Shares, the Additional Shares, the Additional Warrants or
the shares of Common Stock issuable upon the exercise of the Additional
Warrants. The Company has furnished to the Buyer true and correct copies of the
Company's Certificate of Incorporation as in effect on the date hereof
("CERTIFICATE OF INCORPORATION"), the Company's By-laws, as in effect on the
date hereof (the "BY-LAWS"), and the terms of all securities convertible into or
exercisable for Common Stock of the Company and the material rights of the
holders thereof in respect thereto.

                     (d)    ISSUANCE OF SHARES. The Common Shares are duly
authorized and, upon issuance in accordance with the terms of this Agreement,
will be validly issued, fully paid and non-assessable, and free from all taxes,
liens and charges with respect to the issue thereof and shall not be subject to
preemptive rights or other similar rights of stockholders of the Company. The
Warrant Shares, the Additional Shares, and the shares of Common Stock issuable
upon exercise of the Additional Warrants are duly authorized and reserved for
issuance and, upon exercise of the Warrants or the Additional Warrants in
accordance with the terms thereof, or upon issuance of the Additional Shares in
accordance with the terms hereof, will be validly issued, fully paid and
non-assessable, and free from all taxes, liens, claims and encumbrances and will
not be subject to preemptive rights or other similar rights of stockholders of
the Company.

                     (e)    ACKNOWLEDGMENT OF DILUTION. The Company understands
and acknowledges the potentially dilutive effect to the Common Stock upon the
issuance of the Warrant Shares upon exercise of the Warrants, upon the issuance
of the Additional Shares and/or Additional Warrants pursuant hereto, and upon
issuance of the shares of Common Stock issuable upon exercise of the Additional
Warrants. The Company further acknowledges that its obligation to issue Warrant
Shares upon exercise of the Warrants, to issue Additional Shares and/or
Additional Warrants pursuant to the terms hereof, and to issue the shares of
Common Stock issuable upon exercise of the Additional Warrants is absolute and
unconditional regardless of the dilutive effect that such issuance may have on
the ownership interests of other stockholders of the Company.

                     (f)    NO CONFLICTS. The execution, delivery and
performance of this Agreement and the Warrants by the Company and the
consummation by the Company of the transactions contemplated hereby and thereby
(including, without limitation, the issuance and reservation for issuance of the
Common Shares, the Warrant Shares, the Additional Shares and


<PAGE>   6


the shares of Common Stock issuable upon exercise of the Additional Warrants)
will not (i) conflict with or result in a violation of any provision of the
Certificate of Incorporation or By-laws or (ii) violate or conflict with, or
result in a breach of any provision of, or constitute a default (or an event
which with notice or lapse of time or both could become a default) under, or
give to others any rights of termination, amendment, acceleration or
cancellation of, any agreement, indenture or instrument to which the Company or
any of its Subsidiaries is a party, or (iii) result in a violation of any law,
rule, regulation, order, judgment or decree (including federal and state
securities laws and regulations and regulations) applicable to the Company or
any of its Subsidiaries or by which any property or asset of the Company or any
of its Subsidiaries is bound or affected (except for such conflicts, defaults,
terminations, amendments, accelerations, cancellations and violations as would
not, individually or in the aggregate, have a Material Adverse Effect). Neither
the Company nor any of its Subsidiaries is in violation of its Certificate of
Incorporation, By-laws or other organizational documents and neither the Company
nor any of its Subsidiaries is in default (and no event has occurred which with
notice or lapse of time or both could put the Company or any of its Subsidiaries
in default) under, and neither the Company nor any of its Subsidiaries has taken
any action or failed to take any action that would give to others any rights of
termination, amendment, acceleration or cancellation of, any agreement,
indenture or instrument to which the Company or any of its Subsidiaries is a
party or by which any property or assets of the Company or any of its
Subsidiaries is bound or affected, except for possible defaults as would not,
individually or in the aggregate, have a Material Adverse Effect. The businesses
of the Company and its Subsidiaries, if any, are not being conducted, and shall
not be conducted so long as a Buyer owns any of the Securities, in violation of
any law, ordinance or regulation of any governmental entity. Except as
specifically contemplated by this Agreement and as required under the 1933 Act
and any applicable state securities laws and the rules and regulations of
Nasdaq, the Company is not required to obtain any consent, authorization or
order of, or make any filing or registration with, any court, governmental
agency, regulatory agency or self regulatory organization in order for it to
execute, deliver or perform any of its obligations under this Agreement or the
Warrants (or the Additional Warrants) in accordance with the terms hereof or
thereof. Except as disclosed in SCHEDULE 3(f), all consents, authorizations,
orders, filings and registrations which the Company is required to obtain
pursuant to the preceding sentence have been obtained or effected on or prior to
the date hereof. The Company is not in violation of the listing requirements of
Nasdaq and does not reasonably anticipate that the Common Stock will be delisted
by Nasdaq in the foreseeable future. The Company is unaware of any facts or
circumstances which might reasonably be expected to give rise to any of the
foregoing.

                     (g)    SEC DOCUMENTS; FINANCIAL STATEMENTS. Since December
31, 1995, the Company has timely filed all reports, schedules, forms, statements
and other documents required to be filed by it with the SEC pursuant to the
reporting requirements of the 1934 Act (all of the foregoing filed prior to the
date hereof and all exhibits included therein and financial statements and
schedules thereto and documents (other than exhibits) incorporated by reference
therein, being hereinafter referred to herein as the "SEC DOCUMENTS"). The
Company has delivered to each Buyer true and complete copies of the SEC
Documents, except for such exhibits and incorporated documents. As of their
respective dates, the SEC Documents complied in all material respects with the
requirements of the 1934 Act and the rules and regulations of the SEC
promulgated thereunder applicable to the SEC Documents, and none of the SEC
Documents, at the time they were filed with the SEC, contained any untrue
statement of a


<PAGE>   7


material fact or omitted to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. As of their respective
dates, the financial statements of the Company included in the SEC Documents
complied as to form in all material respects with applicable accounting
requirements and the published rules and regulations of the SEC with respect
thereto. Such financial statements have been prepared in accordance with United
States generally accepted accounting principles, consistently applied, during
the periods involved (except (i) as may be otherwise indicated in such financial
statements or the notes thereto, or (ii) in the case of unaudited interim
statements, to the extent they may not include footnotes or may be condensed or
summary statements) and fairly present in all material respects the consolidated
financial position of the Company and its consolidated Subsidiaries as of the
dates thereof and the consolidated results of their operations and cash flows
for the periods then ended (subject, in the case of unaudited statements, to
normal year-end audit adjustments). Except as set forth in the financial
statements of the Company included in the SEC Documents, the Company has no
liabilities, contingent or otherwise, other than (i) liabilities incurred in the
ordinary course of business subsequent to December 31, 1998 and (ii) obligations
under contracts and commitments incurred in the ordinary course of business and
not required under generally accepted accounting principles to be reflected in
such financial statements, which, individually or in the aggregate, are not
material to the financial condition or operating results of the Company.

                     (h)    ABSENCE OF CERTAIN CHANGES. Except for losses
incurred in the ordinary course of business that have been publicly disclosed
prior to the date hereof or as set forth on SCHEDULE 3(h) hereof, since December
31, 1998, there has been no material adverse change and no material adverse
development in the assets, liabilities, business, properties, operations,
financial condition, results of operations or prospects of the Company or any of
its Subsidiaries. For purposes of this Section 3(h), the terms "material adverse
change" and "material adverse development" shall exclude continuing losses that
are consistent with the Company's historical losses.

                     (i)    ABSENCE OF LITIGATION. There is no action, suit,
claim, proceeding, inquiry or investigation before or by any court, public
board, government agency, self-regulatory organization or body pending or, to
the knowledge of the Company or any of its Subsidiaries, threatened against or
affecting the Company or any of its Subsidiaries that could have a Material
Adverse Effect. SCHEDULE 3(i) contains a complete list and summary description
of any pending or threatened proceeding against the Company or any of its
Subsidiaries, without regard to whether it would have a Material Adverse Effect.

                     (j)    PATENTS, COPYRIGHTS, ETC. YEAR 2000 COMPLIANCE.

                            (i)    The Company and each of its Subsidiaries owns
or possesses the requisite licenses or rights to use all patents, patent rights,
inventions, know-how, trade secrets, trademarks, service marks, service names,
trade names and copyrights ("INTELLECTUAL PROPERTY") necessary to enable it to
conduct its business as now operated (and, except as set forth in SCHEDULE 3(j)
hereof, to the best of the Company's knowledge, as presently contemplated to be
operated in the future); there is no claim or action by any person pertaining
to, or proceeding pending, or to the Company's knowledge threatened, which
challenges the right of the Company or of a Subsidiary with respect to any
Intellectual Property necessary to enable it


<PAGE>   8


to conduct its business as now operated (and, except as set forth in SCHEDULE
3(j) hereof, to the best of the Company's knowledge, as presently contemplated
to be operated in the future); to the best of the Company's knowledge, the
Company's or its Subsidiaries' current and intended products, services and
processes do not infringe on any Intellectual Property or other rights held by
any person; and the Company is unaware of any facts or circumstances which might
give rise to any of the foregoing. The Company and each of its Subsidiaries have
taken reasonable security measures to protect the secrecy, confidentiality and
value of their Intellectual Property.

                            (ii)   All of Company's and each of its
Subsidiaries' products and services in the versions which are in present
commercial release (w) accept input and provide output of data involving dates
or portions of dates before, during and after January 1, 2000 in a consistent,
defined, disclosed and unambiguous manner as to the appropriate century, (x)
manage, store, manipulate, sort, sequence and perform calculations with respect
to data involving dates or portions of dates before, during and after January 1,
2000, consistently and accurately, (y) recognize, to the extent that such
products contain functionality which requires the recognition of leap years
generally, the year 2000 as a leap year and (z) operate continuously without
material error, malfunction or interruption caused by or resulting from the
change of the centuries from 1999 to 2000, or the transition from any date in
the twentieth or twenty-first century to any other date in the twentieth or the
twenty-first centuries, and will record, store, process, calculate and present
calendar dates falling on and after (and if applicable, spans of time including)
January 1, 2000 (collectively, "YEAR 2000 COMPLIANT"). As to previously released
versions of the Company's and each of its Subsidiaries' products and services,
the Company either has (x) publicly disclosed and taken commercially reasonable
steps to notify customers of the retirement, effective prior to January 1, 2000,
of such product or service or (y) made available to existing customers, at no
charge, a Year 2000 Compliant version of the same product or service.

                            (iii)  To the Company's knowledge, all of the
Company's and each of its Subsidiaries' Information Technology (as defined
below) is Year 2000 Compliant, and will not cause a material interruption in the
ongoing operations of the Company's or any Subsidiary's business as it is
presently conducted on or after January 1, 2000. For purposes of the foregoing,
the term "INFORMATION TECHNOLOGY" shall mean and include all software, hardware,
firmware, telecommunications systems, network systems, embedded systems and
other systems, components and/or services (other than general utility services
including gas, electric, telephone and postal) that are owned or used by the
Company or any Subsidiary in the conduct of its business.

                     (k)    NO MATERIALLY ADVERSE CONTRACTS, ETC. Neither the
Company nor any of its Subsidiaries is subject to any charter, corporate or
other legal restriction, or any judgment, decree, order, rule or regulation
which in the judgment of the Company's officers has or is expected in the future
to have a Material Adverse Effect. Neither the Company nor any of its
Subsidiaries is a party to any contract or agreement which in the judgment of
the Company's officers has or is expected to have a Material Adverse Effect.

                     (l)    TAX STATUS. Except as set forth on SCHEDULE 3(l),
the Company and each of its Subsidiaries has made or filed all federal and state
income and all other tax returns, reports and declarations required by any
jurisdiction to which it is subject (unless and


<PAGE>   9


only to the extent that the Company and each of its Subsidiaries has set aside
on its books provisions reasonably adequate for the payment of all unpaid and
unreported taxes) and has paid all taxes and other governmental assessments and
charges that are material in amount, shown or determined to be due on such
returns, reports and declarations, except those being contested in good faith
and has set aside on its books provisions reasonably adequate for the payment of
all taxes for periods subsequent to the periods to which such returns, reports
or declarations apply. There are no unpaid taxes in any material amount claimed
to be due by the taxing authority of any jurisdiction, and the officers of the
Company know of no basis for any such claim. The Company has not executed a
waiver with respect to the statute of limitations relating to the assessment or
collection of any foreign, federal, state or local tax. Except as set forth on
SCHEDULE 3(l), none of the Company's tax returns is presently being audited by
any taxing authority.

                     (m)    CERTAIN TRANSACTIONS. Except as set forth on
SCHEDULE 3(m) and except for arm's length transactions pursuant to which the
Company or any of its Subsidiaries makes payments in the ordinary course of
business upon terms no less favorable than the Company or any of its
Subsidiaries could obtain from third parties and other than the grant of stock
options disclosed on SCHEDULE 3(c), none of the officers, directors, or
employees of the Company is presently a party to any transaction with the
Company or any of its Subsidiaries (other than for services as employees,
officers and directors), including any contract, agreement or other arrangement
providing for the furnishing of services to or by, providing for rental of real
or personal property to or from, or otherwise requiring payments to or from any
officer, director or such employee or, to the knowledge of the Company, any
corporation, partnership, trust or other entity in which any officer, director,
or any such employee has a substantial interest or is an officer, director,
trustee or partner.

                     (n)    DISCLOSURE. All information relating to or
concerning the Company or any of its Subsidiaries set forth in this Agreement
and provided to the Buyers pursuant to Section 2(a) hereof and otherwise in
connection with the transactions contemplated hereby, including the prospectus
included in the Registration Statement, is, taken as a whole, true and correct
in all material respects and the Company has not omitted to state any material
fact necessary in order to make the statements made herein or therein, in light
of the circumstances under which they were made, not misleading. Except for the
transactions contemplated hereby, no event or circumstance has occurred or
exists with respect to the Company or any of its Subsidiaries or its or their
business, properties, prospects, operations or financial conditions, which,
under applicable law, rule or regulation, requires public disclosure or
announcement by the Company but which has not been so publicly announced or
disclosed (assuming for this purpose that the Company's reports filed under the
1934 Act are being incorporated into an effective registration statement filed
by the Company under the 1933 Act).

                     (o)    ACKNOWLEDGMENT REGARDING BUYERS' PURCHASE OF
SECURITIES. The Company acknowledges and agrees that the Buyers are acting
solely in the capacity of arm's length purchasers with respect to this
Agreement and the transactions contemplated hereby. The Company further
acknowledges that no Buyer is acting as a financial advisor or fiduciary of the
Company (or in any similar capacity) with respect to this Agreement and the
transactions contemplated hereby and any statement made by any Buyer or any of
their respective representatives or agents in connection with this Agreement
and the transactions contemplated

<PAGE>   10


hereby is not advice or a recommendation and is merely incidental
to the Buyers' purchase of the Securities. The Company further represents to
each Buyer that the Company's decision to enter into this Agreement has been
based solely on the independent evaluation of the Company and its
representatives.

                     (p)    NO INTEGRATED OFFERING. The issuance of the
Securities to the Buyers will not be integrated with any other issuance of the
Company's securities (past, current or future) which requires stockholder
approval under the rules of the Nasdaq Stock Market.

                     (q)    NO BROKERS. The Company has taken no action which
would give rise to any claim by any person for brokerage commissions, finder's
fees or similar payments relating to this Agreement or the transactions
contemplated hereby.

                     (r)    PERMITS; COMPLIANCE. The Company and each of its
Subsidiaries is in possession of all franchises, grants, authorizations,
licenses, permits, easements, variances, exemptions, consents, certificates,
approvals and orders necessary to own, lease and operate its properties and to
carry on its business as it is now being conducted (collectively, the "COMPANY
PERMITS"), and there is no action pending or, to the knowledge of the Company,
threatened regarding suspension or cancellation of any of the Company Permits.
Neither the Company nor any of its Subsidiaries is in conflict with, or in
default or violation of, any of the Company Permits or any law or regulation,
except for any such conflicts, defaults or violations which, individually or in
the aggregate, would not reasonably be expected to have a Material Adverse
Effect. During the period commencing on December 31, 1998 and ending on the date
hereof, neither the Company nor any of its Subsidiaries has received any
notification with respect to possible conflicts, defaults or violations of
applicable laws, except for notices relating to possible conflicts, defaults or
violations, which conflicts, defaults or violations would not have a Material
Adverse Effect.

                     (s)    ENVIRONMENTAL MATTERS.

                            (i)    There are, to the Company's knowledge, with
respect to the Company or any of its Subsidiaries or any predecessor of the
Company, no past or present violations of Environmental Laws (as defined below),
releases of any material into the environment, actions, activities,
circumstances, conditions, events, incidents, or contractual obligations which
may give rise to any common law environmental liability or any liability under
the Comprehensive Environmental Response, Compensation and Liability Act of 1980
or similar federal, state, local or foreign laws and neither the Company nor any
of its Subsidiaries has received any notice with respect to any of the
foregoing, nor is any action pending or, to the Company's knowledge, threatened
in connection with any of the foregoing. The term "ENVIRONMENTAL LAWS" means all
federal, state, local or foreign laws relating to pollution or protection of
human health or the environment (including, without limitation, ambient air,
surface water, groundwater, land surface or subsurface strata), including,
without limitation, laws relating to emissions, discharges, releases or
threatened releases of chemicals, pollutants contaminants, or toxic or hazardous
substances or wastes (collectively, "HAZARDOUS MATERIALS") into the environment,
or otherwise relating to the manufacture, processing, distribution, use,
treatment, storage, disposal, transport or handling of Hazardous Materials, as
well as all authorizations, codes, decrees, demands or demand letters,
injunctions, judgments, licenses,


<PAGE>   11


notices or notice letters, orders, permits, plans or regulations issued,
entered, promulgated or approved thereunder.

                            (ii)   Other than those that are or were stored,
used or disposed of in compliance with applicable law, no Hazardous Materials
are contained on or about any real property currently owned, leased or used by
the Company or any of its Subsidiaries, and no Hazardous Materials were released
on or about any real property previously owned, leased or used by the Company or
any of its Subsidiaries during the period the property was owned, leased or used
by the Company or any of its Subsidiaries, except in the normal course of the
Company's or any of its Subsidiaries' business.

                            (iii)  There are no underground storage tanks on or
under any real property owned, leased or used by the Company or any of its
Subsidiaries that are not in compliance with applicable law.

                     (t)    TITLE TO PROPERTY. The Company and its Subsidiaries
own no real property and have good and marketable title to all personal property
owned by them which is material to the business of the Company and its
Subsidiaries, in each case free and clear of all liens, encumbrances and defects
except such as would not have a Material Adverse Effect. Any real property and
facilities held under lease by the Company and its Subsidiaries are held by them
under valid, subsisting and enforceable leases with such exceptions as would not
have a Material Adverse Effect.

                     (u)    INSURANCE. The Company and each of its Subsidiaries
are insured by insurers of recognized financial responsibility against such
losses and risks and in such amounts as management of the Company believes to be
prudent and customary in the businesses in which the Company and its
Subsidiaries are engaged. Neither the Company nor any such Subsidiary has any
reason to believe that it will not be able to renew its existing insurance
coverage as and when such coverage expires or to obtain similar coverage from
similar insurers as may be necessary to continue its business at a cost that
would not have a Material Adverse Effect.

                     (v)    INTERNAL ACCOUNTING CONTROLS. The Company and each
of its Subsidiaries maintain a system of internal accounting controls
sufficient, in the judgment of the Company's board of directors, to provide
reasonable assurance that (i) transactions are executed in accordance with
management's general or specific authorizations, (ii) transactions are recorded
as necessary to permit preparation of financial statements in conformity with
generally accepted accounting principles and to maintain asset accountability,
(iii) access to assets is permitted only in accordance with management's general
or specific authorization and (iv) the recorded accountability for assets is
compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences.

                     (w)    FOREIGN CORRUPT PRACTICES. Neither the Company, nor
any of its Subsidiaries, nor any director, officer, agent, employee or other
person acting on behalf of the Company or any Subsidiary has, in the course of
his actions for, or on behalf of, the Company, used any corporate funds for any
unlawful contribution, gift, entertainment or other unlawful expenses relating
to political activity; made any direct or indirect unlawful payment to any
foreign or domestic government official or employee from corporate funds;
violated or is in


<PAGE>   12


violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977; or
made any bribe, rebate, payoff, influence payment, kickback or other unlawful
payment to any foreign or domestic government official or employee.

                     (x)    SOLVENCY. The Company (both before and after giving
effect to the transactions contemplated by this Agreement) is solvent (i.e., its
assets have a fair market value in excess of the amount required to pay its
probable liabilities on its existing debts as they become absolute and matured)
and currently the Company has no information that would lead it to reasonably
conclude that the Company would not have the ability to, nor does it intend to
take any action that would impair its ability to, pay its debts from time to
time incurred in connection therewith as such debts mature. The Company did not
receive a qualified opinion from its auditors with respect to its most recent
fiscal year end and does not anticipate or know of any basis upon which its
auditors might issue a qualified opinion in respect of its current fiscal year.

              4.     COVENANTS.

                     (a)    BEST EFFORTS. The parties shall use their best
efforts to satisfy timely each of the conditions described in Section 6 and 7 of
this Agreement.

                     (b)    BLUE SKY LAWS. The Company shall, on or before the
Closing Date, take such action as the Company shall reasonably determine is
necessary to qualify the Securities for sale to the Buyers at the Closing
pursuant to this Agreement under applicable securities or "blue sky" laws of the
states of the United States (or to obtain an exemption from such qualification).

                     (c)    REPORTING STATUS; PROSPECTUS SUPPLEMENT.

                            (i)    The Company's Common Stock is registered
under Section 12(g) of the 1934 Act. So long as any Buyer beneficially owns any
of the Securities, the Company shall timely file all reports required to be
filed with the SEC pursuant to the 1934 Act, and the Company shall not terminate
its status as an issuer required to file reports under the 1934 Act even if the
1934 Act or the rules and regulations thereunder would permit such termination.
The Company currently meets, and will take all necessary action under its
control to continue to meet, the "registrant eligibility" requirements
applicable to the registration of a "primary issuance" by an issuer set forth in
the general instructions to Form S-3 and under Rule 415(a)(x) of the 1933 Act.

                            (ii)   The Company represents and warrants that the
Registration Statement is currently effective and covenants and agrees that it
has filed, or will file prior to the Closing Date, a supplement to the
prospectus included in the Registration Statement which covers the issuance to
the Buyers of the Common Shares, the Warrants and the Warrant Shares. The
Company covenants and agrees to reserve for issuance under the Registration
Statement $6,875,000 of securities to cover its obligations under the Warrants
and under Section 1(a)(ii) and Section 1(a)(iii) hereof. The Company covenants
and agrees that it will, following any adjustment to the number of Warrant
Shares issuable pursuant to the terms of the Warrants, to the extent then
permitted by SEC rules and regulations, file a supplement to the prospectus
included in the Registration Statement which covers the issuance to the Buyers
of such additional


<PAGE>   13


Warrant Shares. In addition, the Company covenants and agrees that it will,
prior to issuance to the Buyers of the Additional Shares and/or the Additional
Warrants, to the extent then permitted by SEC rules and regulations, file a
supplement to the prospectus included in the Registration Statement which covers
the issuance to the Buyers of the Additional Shares, the Additional Warrants and
the shares of Common Stock issuable upon exercise of the Additional Warrants.
The Company further covenants and agrees that it will take all necessary action
to maintain the effectiveness of the Registration Statement so long as any
Warrants and/or Additional Warrants remain outstanding.

                     (d)    USE OF PROCEEDS. The Company shall use the proceeds
from the sale of the Securities for the purpose described in the supplement,
dated August 19, 1999, to the prospectus included in the Registration Statement.
Pending such uses, the Company will invest the proceeds in short-term and
investment-grade securities.

                     (e)    ADDITIONAL EQUITY CAPITAL. Subject to the exceptions
described below, the Company will not, without the prior written consent of Rose
Glen Capital Management, L.P. ("ROSE GLEN"), negotiate or contract with any
party to obtain additional equity financing (including debt financing with an
equity component) that involves (A) the issuance of Common Stock (whether upon
conversion or exercise of a security convertible into or exercisable for Common
Stock) at a discount to the market price of the Common Stock on the date of
issuance thereof or, in the case of a security convertible into or exercisable
for Common Stock, the date of issuance of such convertible security (taking into
account the value of any warrants or options to acquire Common Stock issued in
connection therewith) or (B) the issuance of convertible securities that are
convertible into an indeterminate number of shares of Common Stock ("FUTURE
OFFERINGS") during the period (the "LOCK-UP PERIOD") beginning on the Closing
Date and ending ninety (90) days thereafter. In addition, the Company will not
conduct any Future Offering during the 180-day period immediately following the
expiration of the Lock-Up Period unless it shall have first delivered to the
Buyers, at least ten business days prior to the closing of such Future Offering,
written notice describing the proposed Future Offering, including the terms and
conditions thereof and proposed definitive documentation to be entered into in
connection therewith, and providing the Buyers and their affiliates an option
during the ten business day period following delivery of such notice to purchase
all of the securities being offered in the Future Offering on the same terms as
contemplated by such Future Offering (the limitations referred to in this and
the immediately preceding sentence are collectively referred to as the CAPITAL
RAISING LIMITATIONS"). The Capital Raising Limitations shall not apply to any
transaction involving (i) issuances of securities in a firm commitment
underwritten public offering (excluding a continuous offering pursuant to Rule
415 under the 1933 Act) or (ii) issuances of securities as consideration for a
merger, consolidation or purchase of assets, or in connection with any strategic
partnership or joint venture (the primary purpose of which is not to raise
equity capital), or in connection with the disposition or acquisition of a
business, product or license by the Company. The Capital Raising Limitations
also shall not apply to the issuance of securities upon exercise or conversion
of the Company's options, warrants or other convertible securities outstanding
as of the date hereof or to the grant of additional options or warrants, or the
issuance of additional securities, under any Company stock option or restricted
stock plan approved by the stockholders of the Company.

                     (f)    EXPENSES. At the Closing, the Company shall pay to
Rose Glen a non-accountable expense allowance equal to Thirty Thousand Dollars
($30,000), of which Ten


<PAGE>   14


Thousand Dollars ($10,000) was previously advanced, to cover all expenses
incurred by Rose Glen in connection with the negotiation, preparation,
execution, delivery and performance of this Agreement and the other agreements
to be executed in connection herewith, including, without limitation,
attorneys' and consultants' fees and expenses.

                     (g)    FINANCIAL INFORMATION. The Company agrees to send
(through electronic mail or other reasonable means) the following reports to
each Buyer until such Buyer transfers, assigns, or sells all of the Securities:
(i) within ten (10) days after the filing with the SEC, a copy of its Annual
Report on Form 10-K, its Quarterly Reports on Form 10-Q and any Current Reports
on Form 8-K; (ii) within one (1) day after release, copies of all press releases
issued by the Company or any of its Subsidiaries; and (iii) contemporaneously
with the making available or giving to the stockholders of the Company, copies
of any notices or other information the Company makes available or gives to such
stockholders.

                     (h)    RESERVATION OF SHARES. The Company shall at all
times have authorized, and reserved for the purpose of issuance, a sufficient
number of shares of Common Stock to provide for (i) the full exercise of the
Warrants and issuance of the Warrant Shares in connection therewith (based on
the Exercise Price of the Warrants in effect from time to time), (ii) the
issuance of the Additional Shares pursuant to Section 1(a)(ii) hereof (based on
the market price of the Common Stock in effect from time to time), and (iii) the
issuance of the Additional Warrants pursuant to Section 1(a)(iii) hereof and the
shares of Common Stock issuable upon exercise thereof. The Company shall not
reduce the number of shares of Common Stock reserved for issuance without the
consent of each Buyer. The Company shall use its best efforts at all times to
maintain the number of shares of Common Stock so reserved for issuance at no
less than two (2) times the number that is then actually issuable (i) upon full
exercise of the Warrants (based on the Exercise Price of the Warrants in effect
from time to time) (ii) in connection with its obligation to issue the
Additional Shares pursuant to Section 1(a)(ii) hereof (based on the market price
of the Common Stock in effect from time to time), and (iii) in connection with
its obligation to issue Additional Warrants pursuant to Section 1(a)(iii) hereof
and the number of shares of Common Stock issuable upon exercise thereof. If at
any time the number of shares of Common Stock authorized and reserved for
issuance is below (i) the number of Warrant Shares issued and issuable upon
exercise of the Warrants (based on the Exercise Price of the Warrants then in
effect), (ii) the number of Additional Shares issuable pursuant to Section
1(a)(ii) hereof (based on the market price of the Common Stock in effect from
time to time), and (iii) the number of Additional Warrants issuable pursuant to
Section 1(a)(iii) hereof and the number of shares of Common Stock issuable upon
exercise thereof, the Company will promptly take all corporate action necessary
to authorize and reserve a sufficient number of shares, including, without
limitation, calling a special meeting of stockholders to authorize additional
shares to meet the Company's obligations under this Section 4(h), in the case of
an insufficient number of authorized shares, and using its best efforts to
obtain shareholder approval of an increase in such authorized number of shares.

                     (i)    LISTING. To the extent permitted by Nasdaq, the
Company shall use its best efforts to promptly secure the listing of the Common
Shares, the Warrant Shares, the Additional Shares and the shares of Common Stock
issuable upon exercise of the Additional Warrants upon each national securities
exchange or automated quotation system, if any, upon which shares of Common
Stock are then listed (subject to official notice of issuance) and, so


<PAGE>   15


long as any Buyer owns any of the Securities, shall maintain, so long as any
other shares of Common Stock shall be so listed, such listing of all Common
Shares, the Warrant Shares from time to time issuable upon exercise of the
Warrants, the Additional Shares and the shares of Common Stock from time to time
issuable upon exercise of the Additional Warrants. The Company will obtain and,
so long as any Buyer owns any of the Securities, maintain the listing and
trading of its Common Stock on Nasdaq, Nasdaq SmallCap, the New York Stock
Exchange ("NYSE"), or the American Stock Exchange ("AMEX") and will comply in
all respects with the Company's reporting, filing and other obligations under
the bylaws or rules of the National Association of Securities Dealers ("NASD")
and such exchanges, as applicable. The Company shall promptly provide to each
Buyer copies of any notices it receives from Nasdaq and any other exchanges or
quotation systems on which the Common Stock is then listed regarding the
continued eligibility of the Common Stock for listing on such exchanges and
quotation systems.

                     (j)    CORPORATE EXISTENCE. So long as a Buyer beneficially
owns any Common Shares, Warrants, Additional Shares or Additional Warrants, the
Company shall maintain its corporate existence and shall not sell all or
substantially all of the Company's assets, except in the event of a merger or
consolidation or sale of all or substantially all of the Company's assets, where
the surviving or successor entity in such transaction (i) assumes the Company's
obligations hereunder and under the agreements and instruments entered into in
connection herewith and (ii) is a publicly traded corporation whose Common Stock
is listed for trading on Nasdaq, Nasdaq SmallCap, NYSE or AMEX.

                     (k)    NO INTEGRATION. The Company shall not make any
offers or sales of any security (other than the Securities) under circumstances
that would cause the offering of Securities to be integrated with any other
offering of securities by the Company for the purpose of the stockholder
approval provision of Rule 4460(i) of the Nasdaq Stock Market.

              5.     TRANSFER AGENT INSTRUCTIONS. The Company shall issue
irrevocable instructions to its transfer agent to electronically transmit the
Common Shares, the Warrant Shares, and, if and when issued, the Additional
Shares and the shares of Common Stock issuable upon exercise of the Additional
Warrants, in such amounts as specified from time to time by each Buyer to the
Company, by crediting the account of the Buyer's Prime Broker with the
Depository Trust Company ("DTC") through its Deposit Withdrawal Agent Commission
(" DWAC") system (the "IRREVOCABLE TRANSFER AGENT INSTRUCTIONS"). In the event
that the Company's transfer agent does not participate in DTC's Fast Automated
Securities Transfer program, the Company will cause its transfer agent to issue
certificates representing the Common Shares, the Warrant Shares, the Additional
Shares and the shares of Common Stock issuable upon exercise of the Additional
Warrants in such amounts as specified from time to time by each Buyer to the
Company. Any such certificates shall not bear a restrictive legend.

              6.     CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL. The
obligation of the Company hereunder to issue and sell the Common Shares and
Warrants to a Buyer at the Closing is subject to the satisfaction, at or before

<PAGE>   18


                     (c)    make, or in any way participate in, directly or

       Each party shall provide notice to the other party of any change in
address.

                     (g)    SUCCESSORS AND ASSIGNS. This Agreement shall be
binding upon and inure to the benefit of the parties and their successors and
assigns. Neither the Company nor any Buyer shall assign this Agreement or any
rights or obligations hereunder without the prior written consent of the other
(which consent, in the case of the Company, shall not be unreasonably withheld).
Notwithstanding the foregoing, any Buyer may assign its rights hereunder to any
of its "affiliates," as that term is defined under the 1934 Act.

                     (h)    THIRD PARTY BENEFICIARIES. This Agreement is
intended for the benefit of the parties hereto and their respective permitted
successors and assigns, and is not for the benefit of, nor may any provision
hereof be enforced by, any other person.

                     (i)    SURVIVAL. The representations, warranties,
agreements and covenants set forth in Sections 2, 3, 4, 5 and 8 shall survive
the closing hereunder notwithstanding any due diligence investigation conducted
by or on behalf of the Buyers. The Company agrees to indemnify and hold harmless
each of the Buyers and all their officers, directors, employees and agents for
loss or damage arising as a result of or related to any breach or alleged breach
by the Company of any of its representations, warranties and covenants set forth
in Sections 3 and 4 hereof or any of its covenants and obligations under this
Agreement, including advancement of expenses as they are incurred.

                     (j)    PUBLICITY. The Company and each of the Buyers shall
have the right to review a reasonable period of time before issuance of any
press releases, SEC, Nasdaq or NASD filings, or any other public statements with
respect to the transactions contemplated hereby; provided, however, that the
Company shall be entitled, without the prior approval of each of the Buyers, to
make any press release or SEC, Nasdaq or NASD filings with respect to such
transactions as is required by applicable law and regulations (although each of
the Buyers shall be consulted by the Company in connection with any such press
release prior to its release and shall be provided with a copy thereof and be
given an opportunity to comment thereon).

                     (k)    FURTHER ASSURANCES. Each party shall do and perform,
or cause to be done and performed, all such further acts and things, and shall
execute and deliver all such other agreements, certificates, instruments and
documents, as the other party may reasonably request in order to carry out the
intent and accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

                     (l)    NO STRICT CONSTRUCTION. The language used in this
Agreement will be deemed to be the language chosen by the parties to express
their mutual intent, and no rules of strict construction will be applied against
any party.

                     (m)    REMEDIES. The Company acknowledges that a breach by
it of its obligations hereunder will cause irreparable harm to the Buyers, by
vitiating the intent and purpose of the transactions contemplated hereby.
Accordingly, the Company acknowledges that the remedy at law for a breach of its
obligations under this Agreement will be inadequate and agrees, in the event of
a breach or threatened breach by the Company of the provisions hereunder, that
the Buyers shall be entitled, in addition to all other available remedies at law
or


<PAGE>   21


in equity, to an injunction or injunctions restraining, preventing or curing any
breach of the provisions of this Agreement and to enforce specifically the terms
and provisions hereof, without the necessity of showing economic loss and
without any bond or other security being required.

              IN WITNESS WHEREOF, the undersigned Buyers and the Company have
caused this Agreement to be duly executed as of the date first above written.

                                                               per share

                             STOCK PURCHASE WARRANT

       THIS CERTIFIES THAT, for value received, RGC INTERNATIONAL INVESTORS, LDC
or its registered assigns, is entitled to purchase from CyberCash, Inc., a
Delaware corporation (the "COMPANY"), at any time or from time to time during
the period specified in Section 2 hereof, One Hundred Sixty Four Thousand, Three
Hundred Eighty Four (164,384) fully paid and nonassessable shares of the
Company's Common Stock, par value $.001 per share (the "COMMON STOCK"), at an
exercise price of $11.40622 per share, subject to reset and adjustment as
provided herein (the "EXERCISE PRICE"). The term "WARRANT SHARES," as used
herein, refers to the shares of Common Stock purchasable hereunder. The Warrant
Shares and the Exercise Price are subject to reset and adjustment as provided in
Sections 4 and 5 hereof. The term "WARRANTS" means this Warrant and the other
warrants issued pursuant to that certain Securities Purchase Agreement, dated
August 19, 1999, by and among the Company and the Buyers listed on the execution
page thereof (the "SECURITIES PURCHASE AGREEMENT").

       This Warrant is subject to the following terms, provisions, and
conditions:

       1.     MANNER OF EXERCISE; ISSUANCE OF CERTIFICATES; PAYMENT FOR SHARES.

              (a)    Subject to the provisions hereof, this Warrant may be
exercised by the holder hereof, in whole or in part, by the surrender of this
Warrant, together with a completed exercise agreement in the form attached
hereto (the "EXERCISE AGREEMENT"), to the Company during normal business hours
on any business day at the Company's principal executive offices (or such other
office or agency of the Company as it may designate by notice to the holder
hereof), and upon payment to the Company in cash, by certified or official bank
check or by wire transfer for the account of the Company, of the Exercise Price
for the Warrant Shares specified in the Exercise Agreement. The Warrant Shares
so purchased shall be deemed to be issued to the holder hereof or such holder's
designee, as the record owner of such shares, as of the close of business on the
date on which this Warrant shall have been surrendered, the completed Exercise
Agreement shall have been delivered, and payment shall have been made for such
shares as set forth above. Certificates for the Warrant Shares so purchased,
representing the aggregate number of shares specified in the Exercise Agreement,
shall be delivered to the holder hereof within a reasonable time, not exceeding
three (3) business days, after this Warrant shall have been so exercised. The
certificates so delivered shall be in such denominations as may be


<PAGE>   2


requested by the holder hereof and shall be registered in the name of such
holder or such other name as shall be designated by such holder. If this Warrant
shall have been exercised only in part, then, unless this Warrant has expired,
the Company shall, at its expense, at the time of delivery of such certificates,
deliver to the holder a new Warrant representing the number of shares with
respect to which this Warrant shall not then have been exercised. In lieu of
delivering physical certificates representing the Warrant Shares issuable upon
exercise of this Warrant, provided the Company's transfer agent is participating
in the Depository Trust Company ("DTC") Fast Automated Securities Transfer
program, upon written request of the holder, the Company shall cause its
transfer agent to electronically transmit the Warrant Shares issuable upon
exercise hereof to the holder by crediting the account of the holder's Prime
Broker with DTC through its Deposit Withdrawal Agent Commission ("DWAC") system.
The time period for delivery of the Warrant Shares specified above shall also
apply to the electronic transmittal of the Warrant Shares through the DWAC
system.

              (b)    In the event that, at the time of any exercise of this
Warrant, the issuance of the Warrant Shares to the holder is not then registered
pursuant to the Registration Statement (as defined in Section 5(l)(iv) hereof),
the Company will be obligated, in lieu of issuing Warrant Shares to the holder
pursuant to Section 1(a) above, to pay to the holder an amount in cash equal to
the product of (x) the number of Warrant Shares issuable pursuant to the
Exercise Agreement submitted by the holder to the Company, multiplied by (y) the
difference between (i) the Closing Price (as defined below) of the Common Stock
on the date of the Exercise Agreement minus (ii) the Exercise Price then in
effect. Notwithstanding the provisions of Section 1(a) above, in the event of a
payment by the Company hereunder, the holder shall not be obligated to pay the
Exercise Price for the Warrant Shares specified in the Exercise Agreement. For
purposes of this section, "CLOSING PRICE" shall mean (i) the last sale price of
the Common Stock on the Nasdaq National Market ("NASDAQ"), as reported by
Bloomberg, L.P. ("BLOOMBERG"), on the date that the Exercise Agreement is
delivered, or (ii) if Nasdaq is not the principal trading market for the shares
of Common Stock, the last reported sale price on the principal trading market
for the Common Stock on the date that the Exercise Agreement is delivered, as
reported by Bloomberg, or (iii) if the foregoing do not apply, the last reported
sale price for the Common Stock in the over-the-counter market on the electronic
bulletin board on the date that the Exercise Agreement is delivered, as reported
by Bloomberg, or (iv) if such price cannot be calculated as of such date on any
of the foregoing bases, the Closing Price shall be the fair market value as
reasonably determined in good faith by (a) the Board of Directors of the Company
or, at the option of a majority-in-interest of the holders of the outstanding
Warrants, by (b) an independent investment bank of nationally recognized
standing in the valuation of businesses similar to the business of the Company.

              (c)    Notwithstanding anything in this Warrant to the contrary,
in no event shall the holder of this Warrant be entitled to exercise a number of
Warrants (or portions thereof) in excess of the number of Warrants (or portions
thereof) upon exercise of which the sum of (i) the number of shares of Common
Stock beneficially owned by the holder and its affiliates (other than shares of
Common Stock which may be deemed beneficially owned through the ownership of the
unexercised Warrants and the unexercised or unconverted portion of any other
securities of the Company subject to a limitation on conversion or exercise
analogous to the limitation contained herein) and (ii) the number of shares of
Common Stock issuable upon exercise of the


<PAGE>   3


Warrants (or portions thereof) with respect to which the determination described
herein is being made, would result in beneficial ownership by the holder and its
affiliates of more than 9.9% of the outstanding shares of Common Stock. For
purposes of the immediately preceding sentence, beneficial ownership shall be
determined in accordance with Section 13(d) of the Securities Exchange Act of
1934, as amended, and Regulation 13D-G thereunder, except as otherwise provided
in clause (i) hereof.

       2.     PERIOD OF EXERCISE. This Warrant is exercisable at any time or
from time to time on or after the date on which this Warrant is issued and
delivered pursuant to the terms of the Securities Purchase Agreement (the "ISSUE
DATE") and before 5:00 p.m., New York City time on the fifth (5th) anniversary
of the Issue Date (the "EXERCISE PERIOD").

       3.     CERTAIN AGREEMENTS OF THE COMPANY. The Company hereby covenants
and agrees as follows:

              (a)    SHARES TO BE FULLY PAID. All Warrant Shares will, upon
issuance in accordance with the terms of this Warrant, be validly issued, fully
paid, and nonassessable and free from all taxes, liens, and charges with respect
to the issue thereof.

              (b)    RESERVATION OF SHARES. During the Exercise Period, the
Company shall at all times have authorized and reserved for the purpose of
issuance upon exercise of this Warrant, free from preemptive rights, a
suf-ficient number of shares of Common Stock to provide for the exercise in full
of this Warrant at the then current Exercise Price. As of the date of issuance
of the Warrants, 328,768 authorized and unissued shares of Common Stock have
been duly reserved for issuance upon exercise of the Warrants (the "RESERVED
AMOUNT"). The Reserved Amount shall be increased from time to time in accordance
with the Company's obligations pursuant to Section 4(h) of the Securities
Purchase Agreement. In addition, if the Company shall issue any securities or
make any change in its capital structure which would change the number of shares
of Common Stock into which the Warrants shall be exercisable at the then current
Exercise Price, the Company shall at the same time also make proper provision so
that thereafter there shall be a sufficient number of shares of Common Stock
authorized and reserved, free from preemptive rights, for exercise of the
outstanding Warrants. If at any time a holder of this Warrant submits an
Exercise Agreement, and the Company does not have sufficient authorized but
unissued shares of Common Stock available to effect such exercise in accordance
with the provisions of this Warrant (an "EXERCISE DEFAULT"), the Company shall
issue to the holder all of the shares of Common Stock which are available to
effect such exercise. The portion of this Warrant included in the Exercise
Agreement which exceeds the amount which is then exercisable into available
shares of Common Stock (the "EXCESS AMOUNT") shall, notwithstanding anything to
the contrary contained herein, not be exercisable into Common Stock in
accordance with the terms hereof until (and at the holder's option at any time
after) the date additional shares of Common Stock are authorized by the Company
to permit such exercise, at which time the Exercise Price in respect thereof
shall be the lesser of (i) the Exercise Price on the Exercise Default Date (as
defined below) and (ii) the Exercise Price on the exercise date elected by the
holder in respect thereof. The Company shall use its best efforts to effect an
increase in the authorized number of shares of Common Stock as soon as possible
following the earlier of (i) such time that a holder of Warrants notifies the
Company or that the Company


<PAGE>   4


otherwise becomes aware that there are or likely will be insufficient authorized
and unissued shares to allow full exercise thereof and (ii) an Exercise Default.
In addition, the Company shall pay to the holder payments ("EXERCISE DEFAULT
PAYMENTS") for an Exercise Default in the amount of (a) .24, multiplied by (b)
the Market Value (as defined in Section 5 hereof) on the date of the Exercise
Default of the Warrant Shares which would have been issuable upon exercise of
the Excess Amount, multiplied by (c) (N/365), where N = the number of days from
the day the holder submits an Exercise Agreement giving rise to an Exercise
Default (the "EXERCISE DEFAULT DATE") to the date (the "AUTHORIZATION DATE")
that the Company authorizes a sufficient number of shares of Common Stock to
effect the exercise in full of the Warrants. The Company shall send notice to
the holder of the authorization of additional shares of Common Stock, the
Authorization Date and the amount of the holder's accrued Exercise Default
Payments. The accrued Exercise Default Payment for each calendar month shall be
paid in cash or shall be convertible into Common Stock at the applicable Market
Price, at the holder's option, as follows:

                     (i)    In the event the holder elects to take such payment
in cash, cash payment shall be made to holder by the fifth (5th) day of the
month following the month in which it has accrued; and

                     (ii)   In the event the holder elects to take such payment
in Common Stock, the holder may convert such payment amount into Common Stock at
the Market Price (as in effect at the time of exercise) at any time after the
fifth (5th) day of the month following the month in which it has accrued in
accordance with the terms hereof (so long as there is then a sufficient number
of authorized shares of Common Stock).

              The holder's election shall be made in writing to the Company at
any time prior to 9:00 p.m, New York City time, on the third (3rd) day of the
month following the month in which Exercise Default Payments have accrued. If no
election is made, the holder shall be deemed to have elected to receive cash.
Nothing herein shall limit the holder's right to pursue actual damages (to the
extent in excess of the Exercise Default Payments) for the Company's failure to
maintain a sufficient number of authorized shares of Common Stock, and each
holder shall have the right to pursue all remedies available at law or in equity
(including a decree of specific performance and/or injunctive relief).

              (c)    LISTING. The Company shall, to the extent permitted by
Nasdaq, promptly secure the listing of the shares of Common Stock issuable upon
exercise of the Warrant upon each national securities exchange or automated
quotation system, if any, upon which shares of Common Stock are then listed
(subject to official notice of issuance upon exercise of this Warrant) and shall
maintain, so long as any other shares of Common Stock shall be so listed, such
listing of all shares of Common Stock from time to time issuable upon the
exercise of this Warrant; and the Company shall so list on each national
securities exchange or automated quotation system, as the case may be, and shall
maintain such listing of, any other shares of capital stock of the Company
issuable upon the exercise of this Warrant if and so long as any shares of the
same class shall be listed on such national securities exchange or automated
quotation system.

              (d)    CERTAIN ACTIONS PROHIBITED. The Company will not, by
amendment of its charter or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities, or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed by it hereunder, but will at all times in
good faith assist in the carrying out of all the provisions of this Warrant and
in the taking of all such action as may reasonably be requested by the holder of
this Warrant in order to protect the exercise privilege of the holder of this
Warrant against dilution or other impairment, consistent with the tenor and
purpose of this Warrant. Without limiting the generality of the foregoing, the
Company (i) will not increase the par value of any shares of Common Stock
receivable upon the exercise of this Warrant above the Exercise Price then in
effect, and (ii) will take all such actions as may be necessary or appropriate
in order that the Company may validly and legally issue fully paid and
nonassessable shares of Common Stock upon the exercise of this Warrant.

              (e)    SUCCESSORS AND ASSIGNS. This Warrant will be binding upon
any entity succeeding to the Company by merger, consolidation, or acquisition of
all or substantially all the Company's assets.

       4.     RESET OF EXERCISE PRICE. In the event that the average of the
closing bid prices of the Common Stock for the ten (10) consecutive trading days
ending on the trading day immediately preceding August 19, 2000 (the "ONE YEAR
PRICE") is less than the Exercise Price then in effect, the Exercise Price
shall, beginning on August 19, 2000, equal the One Year Price. In the event of a
reset of the Exercise Price pursuant to this Section 4, the number of Warrant
Shares shall be proportionately increased concurrent with such reset.

       5.     ANTIDILUTION PROVISIONS. During the Exercise Period, the Exercise
Price and the number of Warrant Shares shall be subject to adjustment from time
to time as provided in this Section 5. In the event that any adjustment of the
Exercise Price as required herein results in a fraction of a cent, such Exercise
Price shall be rounded up to the nearest cent.

              (a)    ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES UPON
ISSUANCE OF COMMON STOCK. Except as otherwise provided in Sections 5(c) and 5(e)
hereof, if and whenever on or after August 19, 2000, the Company issues or
sells, or in accordance with Section 5(b) hereof is deemed to have issued or
sold, any shares of Common Stock for no consideration or for a consideration per
share (before deduction of reasonable expenses or commissions or underwriting
discounts or allowances in connection therewith) less than the Market Price (as
hereinafter defined) on the date of issuance of such Common Stock (a "DILUTIVE
ISSUANCE"), then immediately upon the Dilutive Issuance, the Exercise Price will
be reduced to a price determined by multiplying the Exercise Price in effect
immediately prior to the Dilutive Issuance by a fraction, (i) the numerator of
which is an amount equal to the sum of (x) the number of shares of Common Stock
actually outstanding immediately prior to the Dilutive Issuance, plus (y) the
quotient of the aggregate consideration, calculated as set forth in Section 5(b)
hereof, received by the Company upon such Dilutive Issuance divided by the
Market Price in effect immediately prior to the Dilutive Issuance, and (ii) the
denominator of which is the total number of shares of Common Stock Deemed
Outstanding (as defined below) immediately after the Dilutive Issuance.


<PAGE>   6


              (b)    EFFECT ON EXERCISE PRICE OF CERTAIN EVENTS. For purposes of
determining the adjusted Exercise Price under Section 5(a) hereof, the following
will be applicable:

                     (i)    ISSUANCE OF RIGHTS OR OPTIONS. If the Company in any
manner issues or grants any warrants, rights or options, whether or not
immediately exercisable, to subscribe for or to purchase Common Stock or other
securities convertible into or exchangeable for Common Stock ("CONVERTIBLE
SECURITIES") (such warrants, rights and options to purchase Common Stock or
Convertible Securities are hereinafter referred to as "OPTIONS") and the price
per share for which Common Stock is issuable upon the exercise of such Options
is less than the Market Price on the date of issuance or grant of such Options,
then the maximum total number of shares of Common Stock issuable upon the
exercise of all such Options will, as of the date of the issuance or grant of
such Options, be deemed to be outstanding and to have been issued and sold by
the Company for such price per share. For purposes of the preceding sentence,
the "price per share for which Common Stock is issuable upon the exercise of
such Options" is determined by dividing (i) the total amount, if any, received
or receivable by the Company as consideration for the issuance or granting of
all such Options, plus the minimum aggregate amount of additional consideration,
if any, payable to the Company upon the exercise of all such Options, plus, in
the case of Convertible Securities issuable upon the exercise of such Options,
the minimum aggregate amount of additional consideration payable upon the
conversion or exchange thereof at the time such Convertible Securities first
become convertible or exchangeable, by (ii) the maximum total number of shares
of Common Stock issuable upon the exercise of all such Options (assuming full
conversion of Convertible Securities, if applicable). No further adjustment to
the Exercise Price will be made upon the actual issuance of such Common Stock
upon the exercise of such Options or upon the conversion or exchange of
Convertible Securities issuable upon exercise of such Options.

                     (ii)   ISSUANCE OF CONVERTIBLE SECURITIES. If the Company
in any manner issues or sells any Convertible Securities, whether or not
immediately convertible (other than where the same are issuable upon the
exercise of Options), and the price per share for which Common Stock is issuable
upon such conversion or exchange is less than the Market Price on the date of
issuance of such Convertible Securities, then the maximum total number of shares
of Common Stock issuable upon the conversion or exchange of all such Convertible
Securities will, as of the date of the issuance of such Convertible Securities,
be deemed to be outstanding and to have been issued and sold by the Company for
such price per share. For the purposes of the preceding sentence, the "price per
share for which Common Stock is issuable upon such conversion or exchange" is
determined by dividing (i) the total amount, if any, received or receivable by
the Company as consideration for the issuance or sale of all such Convertible
Securities, plus the minimum aggregate amount of additional consideration, if
any, payable to the Company upon the conversion or exchange thereof at the time
such Convertible Securities first become convertible or exchangeable, by (ii)
the maximum total number of shares of Common Stock issuable upon the conversion
or exchange of all such Convertible Securities. No further adjustment to the
Exercise Price will be made upon the actual issuance of such Common Stock upon
conversion or exchange of such Convertible Securities.


<PAGE>   7


                     (iii)  CHANGE IN OPTION PRICE OR CONVERSION RATE. If there
is a change at any time in (i) the amount of additional consideration payable to
the Company upon the exercise of any Options; (ii) the amount of additional
consideration, if any, payable to the Company upon the conversion or exchange of
any Convertible Securities; or (iii) the rate at which any Convertible
Securities are convertible into or exchangeable for Common Stock (other than
under or by reason of provisions designed to protect against dilution), the
Exercise Price in effect at the time of such change will be readjusted to the
Exercise Price which would have been in effect at such time had such Options or
Convertible Securities still outstanding provided for such changed additional
consideration or changed conversion rate, as the case may be, at the time
initially granted, issued or sold.

                     (iv)   TREATMENT OF EXPIRED OPTIONS AND UNEXERCISED
CONVERTIBLE SECURITIES. If, in any case, the total number of shares of Common
Stock issuable upon exercise of any Option or upon conversion or exchange of any
Convertible Securities is not, in fact, issued and the rights to exercise such
Option or to convert or exchange such Convertible Securities shall have expired
or terminated, the Exercise Price then in effect will be readjusted to the
Exercise Price which would have been in effect at the time of such expiration or
termination had such Option or Convertible Securities, to the extent outstanding
immediately prior to such expiration or termination (other than in respect of
the actual number of shares of Common Stock issued upon exercise or conversion
thereof), never been issued.

                     (v)    CALCULATION OF CONSIDERATION RECEIVED. If any Common
Stock, Options or Convertible Securities are issued, granted or sold for cash,
the consideration received therefor for purposes of this Warrant will be the
amount received by the Company therefor, before deduction of reasonable
commissions, underwriting discounts or allowances or other reasonable expenses
paid or incurred by the Company in connection with such issuance, grant or sale.
In case any Common Stock, Options or Convertible Securities are issued or sold
for a consideration part or all of which shall be other than cash, the amount of
the consideration other than cash received by the Company will be the fair value
of such consideration, except where such consideration consists of securities,
in which case the amount of consideration received by the Company will be the
Market Price thereof as of the date of receipt. In case any Common Stock,
Options or Convertible Securities are issued in connection with any acquisition,
merger or consolidation in which the Company is the surviving corporation, the
amount of consideration therefor will be deemed to be the fair value of such
portion of the net assets and business of the non-surviving corporation as is
attributable to such Common Stock, Options or Convertible Securities, as the
case may be. The fair value of any consideration other than cash or securities
will be determined in good faith by the Board of Directors of the Company.

                     (vi)   EXCEPTIONS TO ADJUSTMENT OF EXERCISE PRICE. No
adjustment to the Exercise Price will be made (i) upon the exercise of any
warrants, options or convertible securities granted, issued and outstanding on
the date of issuance of this Warrant; (ii) upon the grant or exercise of any
stock or options which may hereafter be granted or exercised under any employee
benefit plan of the Company now existing or to be implemented in the future, so
long as the issuance of such stock or options is approved by a majority of the
independent members of the Board of Directors of the Company or a majority of
the members of a committee of independent directors established for such
purpose; or (iii) upon the exercise of the Warrants.


<PAGE>   8


              (c)    SUBDIVISION OR COMBINATION OF COMMON STOCK. If the Company
at any time after the Issue Date subdivides (by any stock split, stock dividend,
recapitalization, reorganization, reclassification or otherwise) the shares of
Common Stock acquirable hereunder into a greater number of shares, then, after
the date of record for effecting such subdivision, the Exercise Price in effect
immediately prior to such subdivision will be proportionately reduced. If the
Company at any time after the Issue Date combines (by reverse stock split,
recapitalization, reorganization, reclassification or otherwise) the shares of
Common Stock acquirable hereunder into a smaller number of shares, then, after
the date of record for effecting such combination, the Exercise Price in effect
immediately prior to such combination will be proportionately increased.

              (d)    ADJUSTMENT IN NUMBER OF SHARES. Upon each adjustment of the
Exercise Price pursuant to the provisions of this Section 5, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be adjusted
by multiplying a number equal to the Exercise Price in effect immediately prior
to such adjustment by the number of shares of Common Stock issuable upon
exercise of this Warrant immediately prior to such adjustment and dividing the
product so obtained by the adjusted Exercise Price.

              (e)    CONSOLIDATION, MERGER OR SALE. In case, at any time after
the Issue Date, of any consolidation of the Company with, or merger of the
Company into any other corporation, or in case of any sale or conveyance of all
or substantially all of the assets of the Company other than in connection with
a plan of complete liquidation of the Company, then as a condition of such
consolidation, merger or sale or conveyance, adequate provision will be made
whereby the holder of this Warrant will have the right to acquire and receive
upon exercise of this Warrant in lieu of the shares of Common Stock immediately
theretofore acquirable upon the exercise of this Warrant, such shares of stock,
securities or assets as may be issued or payable with respect to or in exchange
for the number of shares of Common Stock immediately theretofore acquirable and
receivable upon exercise of this Warrant had such consolidation, merger or sale
or conveyance not taken place. In any such case, the Company will make
appropriate provision to insure that the provisions of this Section 5 hereof
will thereafter be applicable as nearly as may be in relation to any shares of
stock or securities thereafter deliverable upon the exercise of this Warrant.
The Company will not effect any consolidation, merger or sale or conveyance
unless prior to the consummation thereof, the successor corporation (if other
than the Company) assumes by written instrument the obligations under this
Section 5 and the obligations to deliver to the holder of this Warrant such
shares of stock, securities or assets as, in accordance with the foregoing
provisions, the holder may be entitled to acquire.

              (f)    DISTRIBUTION OF ASSETS. In case, at any time after the
Issue Date, the Company shall declare or make any distribution of its assets
(including cash) to holders of Common Stock as a partial liquidating dividend,
by way of return of capital or otherwise, then, after the date of record for
determining stockholders entitled to such distribution, but prior to the date of
distribution, the holder of this Warrant shall be entitled upon exercise of this
Warrant for the purchase of any or all of the shares of Common Stock subject
hereto, to receive the amount of such assets which would have been payable to
the holder had such holder been the holder of such shares of Common Stock on the
record date for the determination of stockholders entitled to such distribution.


<PAGE>   9


              (g)    NOTICE OF ADJUSTMENT. Upon the occurrence of any event
which requires any adjustment of the Exercise Price, then, and in each such
case, the Company shall give notice thereof to the holder of this Warrant, which
notice shall state the Exercise Price resulting from such adjustment and the
increase or decrease in the number of Warrant Shares purchasable at such price
upon exercise, setting forth in reasonable detail the method of calculation and
the facts upon which such calculation is based. Such calculation shall be
certified by the chief financial officer of the Company.

              (h)    MINIMUM ADJUSTMENT OF EXERCISE PRICE. No adjustment of the
Exercise Price shall be made in an amount of less than 1% of the Exercise Price
in effect at the time such adjustment is otherwise required to be made, but any
such lesser adjustment shall be carried forward and shall be made at the time
and together with the next subsequent adjustment which, together with any
adjustments so carried forward, shall amount to not less than 1% of such
Exercise Price.

              (i)    NO FRACTIONAL SHARES. No fractional shares of Common Stock
are to be issued upon the exercise of this Warrant, but the Company shall pay a
cash adjustment in respect of any fractional share which would otherwise be
issuable in an amount equal to the same fraction of the Market Price of a share
of Common Stock on the date of such exercise.

              (j)    OTHER NOTICES. In case at any time after the Issue Date:

                     (i)    the Company shall declare any dividend upon the
Common Stock payable in shares of stock of any class or make any other
distribution (including dividends or distributions payable in cash out of
retained earnings) to the holders of the Common Stock;

                     (ii)   the Company shall offer for subscription pro rata to
the holders of the Common Stock any additional shares of stock of any class or
other rights;

                     (iii)  there shall be any capital reorganization of the
Company, or reclassification of the Common Stock, or consolidation or merger of
the Company with or into, or sale of all or substantially all its assets to,
another corporation or entity; or

                     (iv)   there shall be a voluntary or involuntary
dissolution, liquidation or winding-up of the Company;

then, in each such case, the Company shall give to the holder of this Warrant
(a) notice of the date on which the books of the Company shall close or a record
shall be taken for determining the holders of Common Stock entitled to receive
any such dividend, distribution, or subscription rights or for determining the
holders of Common Stock entitled to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up and (b) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding-up, notice of
the date (or, if not then known, a reasonable approximation thereof by the
Company) when the same shall take place. Such notice shall also specify the date
on which the holders of Common Stock shall be entitled to receive


<PAGE>   10


such dividend, distribution, or subscription rights or to exchange their Common
Stock for stock or other securities or property deliverable upon such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding-up, as the case may be. Such notice shall be given at
least 30 days prior to the record date or the date on which the Company's books
are closed in respect thereto. Failure to give any such notice or any defect
therein shall not affect the validity of the proceedings referred to in clauses
(i), (ii), (iii) and (iv) above.

              (k)    CERTAIN EVENTS. If any event occurs of the type
contemplated by the adjustment provisions of this Section 5 but not expressly
provided for by such provisions, the Company will give notice of such event as
provided in Section 5(g) hereof, and the Company's Board of Directors will make
an appropriate adjustment in the Exercise Price and the number of shares of
Common Stock acquirable upon exercise of this Warrant so that the rights of the
holder shall be neither enhanced nor diminished by such event.

              (l)    CERTAIN DEFINITIONS.

                     (i)    "COMMON STOCK DEEMED OUTSTANDING" shall mean the
number of shares of Common Stock actually outstanding (not including shares of
Common Stock held in the treasury of the Company), plus (x) pursuant to Section
5(b)(i) hereof, the maximum total number of shares of Common Stock issuable upon
the exercise of Options, as of the date of such issuance or grant of such
Options, if any, and (y) pursuant to Section 5(b)(ii) hereof, the maximum total
number of shares of Common Stock issuable upon conversion or exchange of
Convertible Securities, as of the date of issuance of such Convertible
Securities, if any.

                     (ii)   "MARKET PRICE," as of any date, (i) means the
average of the last reported sale prices for the shares of Common Stock on
Nasdaq for the five (5) trading days immediately preceding such date as reported
by Bloomberg, or (ii) if Nasdaq is not the principal trading market for the
shares of Common Stock, the average of the last reported sale prices on the
principal trading market for the Common Stock during the same period as reported
by Bloomberg, or (iii) if the foregoing do not apply, the average of the last
reported sale prices in the over-the-counter market on the electronic bulletin
board for the Common Stock during the same period, as reported by Bloomberg, or
(iv) if market value cannot be calculated as of such date on any of the
foregoing bases, the Market Price shall be the fair market value as reasonably
determined in good faith by (a) the Board of Directors of the Corporation or, at
the option of a majority-in-interest of the holders of the outstanding Warrants,
by (b) an independent investment bank of nationally recognized standing in the
valuation of businesses similar to the business of the Company. The manner of
determining the Market Price of the Common Stock set forth in the foregoing
definition shall apply with respect to any other security in respect of which a
determination as to market value must be made hereunder.

                     (iii)  " COMMON STOCK," for purposes of this Section 5,
includes the Common Stock, par value $.001 per share, and any additional class
of stock of the Company having no preference as to dividends or distributions on
liquidation, provided that the shares purchasable pursuant to this Warrant shall
include only shares of Common Stock, par value $.001 per share, in respect of
which this Warrant is exercisable, or shares resulting from any subdivision or
combination of such Common Stock, or in the case of any reorganization,


<PAGE>   11


reclassification, consolidation, merger, or sale of the character referred to in
Section 5(e) hereof, the stock or other securities or property provided for in
such Section.

                     (iv)   "REGISTRATION STATEMENT" means the Company's
Registration Statement on Form S-3, Registration No. 333-79943, which was
declared effective by the Securities and Exchange Commission on June 18, 1999
and any successor registration statement filed pursuant to Rule 429 under the
Securities Act of 1933, as amended.

       6.     ISSUE TAX. The issuance of certificates for Warrant Shares upon
the exercise of this Warrant shall be made without charge to the holder of this
Warrant or such shares for any issuance tax or other costs in respect thereof,
provided that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than the holder of this Warrant.

       7.     NO RIGHTS OR LIABILITIES AS A SHAREHOLDER. This Warrant shall not
entitle the holder hereof to any voting rights or other rights as a shareholder
of the Company. No provision of this Warrant, in the absence of affirmative
action by the holder hereof to purchase Warrant Shares, and no mere enumeration
herein of the rights or privileges of the holder hereof, shall give rise to any
liability of such holder for the Exercise Price or as a shareholder of the
Company, whether such liability is asserted by the Company or by creditors of
the Company.

       8.     TRANSFER, EXCHANGE, AND REPLACEMENT OF WARRANT.

              (a)    TRANSFER. This Warrant and the rights granted to the holder
hereof are transferable, in whole or in part, upon surrender of this Warrant,
together with a properly executed assignment in the form attached hereto, at the
office or agency of the Company referred to in Section 8(e) below. Until due
presentment for registration of transfer on the books of the Company, the
Company may treat the registered holder hereof as the owner and holder hereof
for all purposes, and the Company shall not be affected by any notice to the
contrary.

              (b)    WARRANT EXCHANGEABLE FOR DIFFERENT DENOMINATIONS. This
Warrant is exchangeable, upon the surrender hereof by the holder hereof at the
office or agency of the Company referred to in Section 8(e) below, for new
Warrants of like tenor representing in the aggregate the right to purchase the
number of shares of Common Stock which may be purchased hereunder, each of such
new Warrants to represent the right to purchase such number of shares as shall
be designated by the holder hereof at the time of such surrender.

              (c)    REPLACEMENT OF WARRANT. Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction, or mutilation of
this Warrant and, in the case of any such loss, theft, or destruction, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the Company, or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Company, at its expense, will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

              (d)    CANCELLATION; PAYMENT OF EXPENSES. Upon the surrender of
this Warrant in connection with any transfer, exchange, or replacement as

pursuant to this Section 8.

              (e)    REGISTER. The Company shall maintain, at its principal
executive offices (or such other office or agency of the Company as it may
designate by notice to the holder hereof), a register for this Warrant, in which
the Company shall record the name and address of the person in whose name this
Warrant has been issued, as well as the name and address of each transferee and
each prior owner of this Warrant.

or permitted to be given or delivered hereunder to the holder of this Warrant
shall be in writing, and shall be personally delivered, or shall be sent by
certified or registered mail or by recognized overnight mail courier, postage
prepaid and addressed, to such holder at the address shown for such holder on
the books of the Company, or at such other address as shall have been furnished
to the Company by notice from such holder. All notices, requests, and other
communications required or permitted to be given or delivered hereunder to the

United States Post Office or such overnight mail courier, if postage is prepaid
and the mailing is properly addressed, as the case may be.

       10.    GOVERNING LAW. THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED
AND ENFORCED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF DELAWARE
WITHOUT REGARD TO THE BODY OF LAW CONTROLLING CONFLICTS OF LAW.

       11.    MISCELLANEOUS.

              (c)    REMEDIES. The Company acknowledges that a breach by it of
its obligations hereunder will cause irreparable harm to the holder hereof, by
vitiating the intent and purpose of the transactions contemplated hereby.
Accordingly, the Company acknowledges that the remedy at law for a breach of its
obligations under this Warrant will be inadequate and agrees, in the event of a
breach or threatened breach by the Company of the provisions hereunder, that the
holder shall be entitled, in addition to all other available remedies at law or
in equity, to an injunction or injunctions restraining, preventing or curing any
breach of this Warrant and to enforce specifically the terms and provisions
hereof, without the necessity of showing economic loss and without any bond or
other security being required.

       IN WITNESS WHEREOF, the Company has caused this Warrant to be signed by
its duly authorized officer.

                                                               per share


                        ADDITIONAL STOCK PURCHASE WARRANT

       THIS CERTIFIES THAT, for value received, RGC INTERNATIONAL INVESTORS, LDC
or its registered assigns, is entitled to purchase from CyberCash, Inc., a
Delaware corporation (the "COMPANY"), at any time or from time to time during
the period specified in Section 2 hereof, _____________________________(_______)
fully paid and nonassessable shares of the Company's Common Stock, par value
$.001 per share (the "COMMON STOCK"), at an exercise price of $.01 per share
(the "EXERCISE PRICE"). The term "WARRANT SHARES," as used herein, refers to the
shares of Common Stock purchasable hereunder. The term "WARRANTS" means this
Warrant and the other Additional Warrants issuable pursuant to that certain
Securities Purchase Agreement, dated August 19, 1999, by and among the Company
and the Buyers listed on the execution page thereof (the "SECURITIES PURCHASE
AGREEMENT").

       This Warrant is subject to the following terms, provisions, and
conditions:

       1.     MANNER OF EXERCISE; ISSUANCE OF CERTIFICATES; PAYMENT FOR SHARES.

              (a)    Subject to the provisions hereof, this Warrant may be
exercised by the holder hereof, in whole or in part, by the surrender of this
Warrant, together with a completed exercise agreement in the form attached
hereto (the "EXERCISE AGREEMENT"), to the Company during normal business hours
on any business day at the Company's principal executive offices (or such other
office or agency of the Company as it may designate by notice to the holder
hereof), and upon payment to the Company in cash, by certified or official bank
check or by wire transfer for the account of the Company, of the Exercise Price
for the Warrant Shares specified in the Exercise Agreement. The Warrant Shares
so purchased shall be deemed to be issued to the holder hereof or such holder's
designee, as the record owner of such shares, as of the close of business on the
date on which this Warrant shall have been surrendered, the completed Exercise
Agreement shall have been delivered, and payment shall have been made for such
shares as set forth above. Certificates for the Warrant Shares so purchased,
representing the aggregate number of shares specified in the Exercise Agreement,
shall be delivered to the holder hereof within a reasonable time, not exceeding
three (3) business days, after this Warrant shall have been so exercised. The
certificates so delivered shall be in such denominations as may be


<PAGE>   2


requested by the holder hereof and shall be registered in the name of such
holder or such other name as shall be designated by such holder. If this Warrant
shall have been exercised only in part, then, unless this Warrant has expired,
the Company shall, at its expense, at the time of delivery of such certificates,
deliver to the holder a new Warrant representing the number of shares with
respect to which this Warrant shall not then have been exercised. In lieu of
delivering physical certificates representing the Warrant Shares issuable upon
exercise of this Warrant, provided the Company's transfer agent is participating
in the Depository Trust Company ("DTC") Fast Automated Securities Transfer
program, upon written request of the holder, the Company shall cause its
transfer agent to electronically transmit the Warrant Shares issuable upon
exercise hereof to the holder by crediting the account of the holder's Prime
Broker with DTC through its Deposit Withdrawal Agent Commission ("DWAC") system.
The time period for delivery of the Warrant Shares specified above shall also
apply to the electronic transmittal of the Warrant Shares through the DWAC
system.

              (b)    In the event that, at the time of any exercise of this
Warrant, the issuance of the Warrant Shares to the holder is not then registered
pursuant to the Registration Statement (as defined in Section 5(l)(iv) hereof),
the Company will be obligated, in lieu of issuing Warrant Shares to the holder
pursuant to Section 1(a) above, to pay to the holder an amount in cash equal to
the product of (x) the number of Warrant Shares issuable pursuant to the
Exercise Agreement submitted by the holder to the Company, multiplied by (y) the
difference between (i) the Closing Price (as defined below) of the Common Stock
on the date of the Exercise Agreement minus (ii) the Exercise Price then in
effect. Notwithstanding the provisions of Section 1(a) above, in the event of a
payment by the Company hereunder, the holder shall not be obligated to pay the
Exercise Price for the Warrant Shares specified in the Exercise Agreement. For
purposes of this section, "CLOSING PRICE" shall mean (i) the last sale price of
the Common Stock on the Nasdaq National Market ("NASDAQ"), as reported by
Bloomberg, L.P. ("BLOOMBERG"), on the date that the Exercise Agreement is
delivered, or (ii) if Nasdaq is not the principal trading market for the shares
of Common Stock, the last reported sale price on the principal trading market
for the Common Stock on the date that the Exercise Agreement is delivered, as
reported by Bloomberg, or (iii) if the foregoing do not apply, the last reported
sale price for the Common Stock in the over-the-counter market on the electronic
bulletin board on the date that the Exercise Agreement is delivered, as reported
by Bloomberg, or (iv) if such price cannot be calculated as of such date on any
of the foregoing bases, the Closing Price shall be the fair market value as
reasonably determined in good faith by (a) the Board of Directors of the Company
or, at the option of a majority-in-interest of the holders of the outstanding
Warrants, by (b) an independent investment bank of nationally recognized
standing in the valuation of businesses similar to the business of the Company.

              (c)    Notwithstanding anything in this Warrant to the contrary,
in no event shall the holder of this Warrant be entitled to exercise a number of
Warrants (or portions thereof) in excess of the number of Warrants (or portions
thereof) upon exercise of which the sum of (i) the number of shares of Common
Stock beneficially owned by the holder and its affiliates (other than shares of
Common Stock which may be deemed beneficially owned through the ownership of the
unexercised Warrants and the unexercised or unconverted portion of any other
securities of the Company subject to a limitation on conversion or exercise
analogous to the limitation contained herein) and (ii) the number of shares of
Common Stock issuable upon exercise of the


<PAGE>   3


Warrants (or portions thereof) with respect to which the determination described
herein is being made, would result in beneficial ownership by the holder and its
affiliates of more than 9.9% of the outstanding shares of Common Stock. For
purposes of the immediately preceding sentence, beneficial ownership shall be
determined in accordance with Section 13(d) of the Securities Exchange Act of
1934, as amended, and Regulation 13D-G thereunder, except as otherwise provided
in clause (i) hereof.

       2.     PERIOD OF EXERCISE. This Warrant is exercisable at any time or
from time to time on or after the date on which this Warrant is issued and
delivered pursuant to the terms of the Securities Purchase Agreement (the "ISSUE
DATE") and before 5:00 p.m., New York City time on January 5, 2002 (the
"EXERCISE PERIOD").

       3.     CERTAIN AGREEMENTS OF THE COMPANY. The Company hereby covenants
and agrees as follows:

              (a)    SHARES TO BE FULLY PAID. All Warrant Shares will, upon
issuance in accordance with the terms of this Warrant, be validly issued, fully
paid, and nonassessable and free from all taxes, liens, and charges with respect
to the issue thereof.

              (b)    RESERVATION OF SHARES. During the Exercise Period, the
Company shall at all times have authorized and reserved for the purpose of
issuance upon exercise of this Warrant, free from preemptive rights, a
suf-ficient number of shares of Common Stock to provide for the exercise in full
of this Warrant at the then current Exercise Price. In addition, if the Company
shall issue any securities or make any change in its capital structure which
would change the number of shares of Common Stock into which the Warrants shall
be exercisable at the then current Exercise Price, the Company shall at the same
time also make proper provision so that thereafter there shall be a sufficient
number of shares of Common Stock authorized and reserved, free from preemptive
rights, for exercise of the outstanding Warrants. If at any time a holder of
this Warrant submits an Exercise Agreement, and the Company does not have
sufficient authorized but unissued shares of Common Stock available to effect
such exercise in accordance with the provisions of this Warrant (an "EXERCISE
DEFAULT"), the Company shall issue to the holder all of the shares of Common
Stock which are available to effect such exercise. The portion of this Warrant
included in the Exercise Agreement which exceeds the amount which is then
exercisable into available shares of Common Stock (the "EXCESS AMOUNT") shall,
notwithstanding anything to the contrary contained herein, not be exercisable
into Common Stock in accordance with the terms hereof until (and at the holder's
option at any time after) the date additional shares of Common Stock are
authorized by the Company to permit such exercise. The Company shall use its
best efforts to effect an increase in the authorized number of shares of Common
Stock as soon as possible following the earlier of (i) such time that a holder
of Warrants notifies the Company or that the Company otherwise becomes aware
that there are or likely will be insufficient authorized and unissued shares to
allow full exercise thereof and (ii) an Exercise Default. In addition, the
Company shall pay to the holder payments ("EXERCISE DEFAULT PAYMENTS") for an
Exercise Default in the amount of (a) .24, multiplied by (b) the Market Value
(as defined in Section 5 hereof) on the date of the Exercise Default of the
Warrant Shares which would have been issuable upon exercise of the Excess
Amount, multiplied by (c) (N/365), where N = the number of days from the day the
holder submits an Exercise Agreement giving rise to an


<PAGE>   4


Exercise Default (the "EXERCISE DEFAULT DATE") to the date (the "AUTHORIZATION
DATE") that the Company authorizes a sufficient number of shares of Common Stock
to effect the exercise in full of the Warrants. The Company shall send notice to
the holder of the authorization of additional shares of Common Stock, the
Authorization Date and the amount of the holder's accrued Exercise Default
Payments. The accrued Exercise Default Payment for each calendar month shall be
paid in cash or shall be convertible into Common Stock at the applicable Market
Price, at the holder's option, as follows:

                     (i)    In the event the holder elects to take such payment
in cash, cash payment shall be made to holder by the fifth (5th) day of the
month following the month in which it has accrued; and

                     (ii)   In the event the holder elects to take such payment
in Common Stock, the holder may convert such payment amount into Common Stock at
the Market Price (as in effect at the time of exercise) at any time after the
fifth (5th) day of the month following the month in which it has accrued in
accordance with the terms hereof (so long as there is then a sufficient number
of authorized shares of Common Stock).

              The holder's election shall be made in writing to the Company at
any time prior to 9:00 p.m, New York City time, on the third (3rd) day of the
month following the month in which Exercise Default Payments have accrued. If no
election is made, the holder shall be deemed to have elected to receive cash.
Nothing herein shall limit the holder's right to pursue actual damages (to the
extent in excess of the Exercise Default Payments) for the Company's failure to
maintain a sufficient number of authorized shares of Common Stock, and each
holder shall have the right to pursue all remedies available at law or in equity
(including a decree of specific performance and/or injunctive relief).

              (c)    LISTING. The Company shall, to the extent permitted by
Nasdaq, promptly secure the listing of the shares of Common Stock issuable upon
exercise of the Warrant upon each national securities exchange or automated
quotation system, if any, upon which shares of Common Stock are then listed
(subject to official notice of issuance upon exercise of this Warrant) and shall
maintain, so long as any other shares of Common Stock shall be so listed, such
listing of all shares of Common Stock from time to time issuable upon the
exercise of this Warrant; and the Company shall so list on each national
securities exchange or automated quotation system, as the case may be, and shall
maintain such listing of, any other shares of capital stock of the Company
issuable upon the exercise of this Warrant if and so long as any shares of the
same class shall be listed on such national securities exchange or automated
quotation system.

              (d)    CERTAIN ACTIONS PROHIBITED. The Company will not, by
amendment of its charter or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities, or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed by it hereunder, but will at all times in
good faith assist in the carrying out of all the provisions of this Warrant and
in the taking of all such action as may reasonably be requested by the holder of
this Warrant in order to protect the exercise privilege of the holder of this
Warrant against dilution or other impairment, consistent


<PAGE>   5


with the tenor and purpose of this Warrant. Without limiting the generality of
the foregoing, the Company (i) will not increase the par value of any shares of
Common Stock receivable upon the exercise of this Warrant above the Exercise
Price then in effect, and (ii) will take all such actions as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of Common Stock upon the exercise of this Warrant.

              (e)    SUCCESSORS AND ASSIGNS. This Warrant will be binding upon
any entity succeeding to the Company by merger, consolidation, or acquisition of
all or substantially all the Company's assets.

       4.     ANTIDILUTION PROVISIONS. During the Exercise Period, the number of
Warrant Shares shall be subject to adjustment from time to time as provided in
this Section 4.

              (a)    SUBDIVISION OR COMBINATION OF COMMON STOCK. If the Company
at any time after the Issue Date subdivides (by any stock split, stock dividend,
recapitalization, reorganization, reclassification or otherwise) the shares of
Common Stock acquirable hereunder into a greater number of shares, then, after
the date of record for effecting such subdivision, the number of Warrant Shares
issuable upon exercise hereof will be proportionately increased. If the Company
at any time after the Issue Date combines (by reverse stock split,
recapitalization, reorganization, reclassification or otherwise) the shares of
Common Stock acquirable hereunder into a smaller number of shares, then, after
the date of record for effecting such combination, the number of Warrant Shares
issuable upon exercise hereof will be proportionately decreased.

              (b)    CONSOLIDATION, MERGER OR SALE. In case, at any time after
the Issue Date, of any consolidation of the Company with, or merger of the
Company into any other corporation, or in case of any sale or conveyance of all
or substantially all of the assets of the Company other than in connection with
a plan of complete liquidation of the Company, then as a condition of such
consolidation, merger or sale or conveyance, adequate provision will be made
whereby the holder of this Warrant will have the right to acquire and receive
upon exercise of this Warrant in lieu of the shares of Common Stock immediately
theretofore acquirable upon the exercise of this Warrant, such shares of stock,
securities or assets as may be issued or payable with respect to or in exchange
for the number of shares of Common Stock immediately theretofore acquirable and
receivable upon exercise of this Warrant had such consolidation, merger or sale
or conveyance not taken place. In any such case, the Company will make
appropriate provision to insure that the provisions of this Section 4 hereof
will thereafter be applicable as nearly as may be in relation to any shares of
stock or securities thereafter deliverable upon the exercise of this Warrant.
The Company will not effect any consolidation, merger or sale or conveyance
unless prior to the consummation thereof, the successor corporation (if other
than the Company) assumes by written instrument the obligations under this
Section 4 and the obligations to deliver to the holder of this Warrant such
shares of stock, securities or assets as, in accordance with the foregoing
provisions, the holder may be entitled to acquire.

              (c)    DISTRIBUTION OF ASSETS. In case, at any time after the
Issue Date, the Company shall declare or make any distribution of its assets
(including cash) to holders of Common Stock as a partial liquidating dividend,
by way of return of capital or otherwise, then, after the date of record for
determining stockholders entitled to such distribution, but prior to the


<PAGE>   6


date of distribution, the holder of this Warrant shall be entitled upon exercise
of this Warrant for the purchase of any or all of the shares of Common Stock
subject hereto, to receive the amount of such assets which would have been
payable to the holder had such holder been the holder of such shares of Common
Stock on the record date for the determination of stockholders entitled to such
distribution.

              (d)    NOTICE OF ADJUSTMENT. Upon the occurrence of any event
which requires any adjustment hereunder, then, and in each such case, the
Company shall give notice thereof to the holder of this Warrant, which notice
shall state the increase or decrease in the number of Warrant Shares purchasable
at the Exercise Price, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based. Such calculation
shall be certified by the chief financial officer of the Company.

              (e)    NO FRACTIONAL SHARES. No fractional shares of Common Stock
are to be issued upon the exercise of this Warrant, but the Company shall pay a
cash adjustment in respect of any fractional share which would otherwise be
issuable in an amount equal to the same fraction of the Market Price of a share
of Common Stock on the date of such exercise.

              (f)    OTHER NOTICES. In case at any time after the Issue Date:

                     (i)    the Company shall declare any dividend upon the
Common Stock payable in shares of stock of any class or make any other
distribution (including dividends or distributions payable in cash out of
retained earnings) to the holders of the Common Stock;

                     (ii)   the Company shall offer for subscription pro rata to
the holders of the Common Stock any additional shares of stock of any class or
other rights;

                     (iii)  there shall be any capital reorganization of the
Company, or reclassification of the Common Stock, or consolidation or merger of
the Company with or into, or sale of all or substantially all its assets to,
another corporation or entity; or

                     (iv)   there shall be a voluntary or involuntary
dissolution, liquidation or winding-up of the Company;

then, in each such case, the Company shall give to the holder of this Warrant
(a) notice of the date on which the books of the Company shall close or a record
shall be taken for determining the holders of Common Stock entitled to receive
any such dividend, distribution, or subscription rights or for determining the
holders of Common Stock entitled to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up and (b) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding-up, notice of
the date (or, if not then known, a reasonable approximation thereof by the
Company) when the same shall take place. Such notice shall also specify the date
on which the holders of Common Stock shall be entitled to receive such dividend,
distribution, or subscription rights or to exchange their Common Stock for stock
or other securities or property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation, or
winding-up, as the case may be. Such


<PAGE>   7


notice shall be given at least 30 days prior to the record date or the date on
which the Company's books are closed in respect thereto. Failure to give any
such notice or any defect therein shall not affect the validity of the
proceedings referred to in clauses (i), (ii), (iii) and (iv) above.

              (g)    CERTAIN DEFINITIONS.

                     (i)    "COMMON STOCK," for purposes of this Section 4,
includes the Common Stock, par value $.001 per share, and any additional class
of stock of the Company having no preference as to dividends or distributions on
liquidation, provided that the shares purchasable pursuant to this Warrant shall
include only shares of Common Stock, par value $.001 per share, in respect of
which this Warrant is exercisable, or shares resulting from any subdivision or
combination of such Common Stock, or in the case of any reorganization,
reclassification, consolidation, merger, or sale of the character referred to in
Section 4(b) hereof, the stock or other securities or property provided for in
such Section.

                     (ii)   "MARKET PRICE," as of any date, (i) means the
average of the last reported sale prices for the shares of Common Stock on
Nasdaq for the five (5) trading days immediately preceding such date as reported
by Bloomberg, or (ii) if Nasdaq is not the principal trading market for the
shares of Common Stock, the average of the last reported sale prices on the
principal trading market for the Common Stock during the same period as reported
by Bloomberg, or (iii) if the foregoing do not apply, the average of the last
reported sale prices in the over-the-counter market on the electronic bulletin
board for the Common Stock during the same period, as reported by Bloomberg, or
(iv) if market value cannot be calculated as of such date on any of the
foregoing bases, the Market Price shall be the fair market value as reasonably
determined in good faith by (a) the Board of Directors of the Corporation or, at
the option of a majority-in-interest of the holders of the outstanding Warrants,
by (b) an independent investment bank of nationally recognized standing in the
valuation of businesses similar to the business of the Company. The manner of
determining the Market Price of the Common Stock set forth in the foregoing
definition shall apply with respect to any other security in respect of which a
determination as to market value must be made hereunder.

                     (iii)  "REGISTRATION STATEMENT" means the Company's

its duly authorized officer.
