named on the signature page hereof (the "Buyer").

                                    RECITALS

         A. The Company and the Buyer are executing and delivering this
Agreement in reliance upon the exemption from securities registration afforded
by the provisions of Regulation D ("Regulation D") as promulgated by the United
States Securities and Exchange Commission (the "SEC") under the Securities Act
of 1933, as amended (the "1933 Act") and Section 4(2) under the 1933 Act;

         B. The Buyer desires to purchase from the Company, and the Company
desires to sell to the Buyer, for the amounts and upon the terms and conditions
stated in this Agreement, in a closing (the "Closing") as herein described,
certain of the Company's convertible preferred stock as listed and described in
Recital B(i) immediately below, and certain warrants as listed and described in
Recital B(ii) below.

                  (i)      At the Closing (the "Closing"), 1,250 shares of the
                           Company's Series B Convertible Preferred Stock (the
                           "Preferred Stock"). The designation, rights,
                           preferences and other terms and provisions of the
                           Preferred Stock are set forth in the Certificate of
                           Designation of the Relative Rights and Preferences of
                           the Series B Convertible Preferred Stock of
                           IPVoice.Com, Inc., attached hereto as Exhibit A (the
                           "Certificate of Designations"). The Preferred Stock
                           may be converted into common stock of the Company,
                           $.001 par value per share ("Common Stock"), upon the
                           terms and conditions hereof and upon the terms and
                           conditions of the Certificate of Designations. The
                           Preferred Stock also contains an option (the
                           "Option") to purchase additional Common Stock
                           ("Option Shares") as described in the Certificate of
                           Designations. The purchase price for the Preferred
                           Stock sold pursuant to this Agreement shall be as
                           stated in Section 1(a) below. The total aggregate
                           number of shares of Preferred Stock to be issued and
                           sold by the Company at this Closing is two thousand
                           five hundred (2,500), and the purchase price for each
                           share of Preferred Stock is $1,000.00, all in
                           accordance with the terms of this Agreement and of
                           the Certificate of Designations.

                  (ii)     At the Closing, as additional consideration for
                           Buyer's purchase of the Preferred Stock, a warrant
                           (the "Warrants") to purchase 125,000 shares of Common
                           Stock at a purchase price per share equal to one
                           hundred twenty percent (120%) of the lowest of the
                           closing bid prices for the Common Stock for the five
                           (5) trading days prior to the Closing Date (defined
                           below), which
<PAGE>   2
                           Warrants must be exercised if at all within five (5)
                           years after the date of issuance. The Warrants shall
                           be substantially in the form attached hereto as
                           Exhibit B.

         The Common Stock into which the Preferred Stock may (in accordance with
the terms of the Certificate of Designations) be convertible shall be referred
to herein as the "Conversion Shares." Certain shares of Common Stock may (at the
Company's option as described in the Certificate of Designations) be issued to
the Buyer in payment of dividends (the "Dividend Shares"). The Common Stock
received upon exercise of the Warrants shall be referred to as the "Warrant
Shares." The Conversion Shares, the Option Shares, the Dividend Shares (if any),
the Warrants and the Warrant Shares may be collectively referred to herein as
the "Securities."

         C. Contemporaneously with the execution and delivery of this Agreement,
the parties hereto are executing and delivering a Registration Rights Agreement
(the "Registration Rights Agreement") substantially in the form of Exhibit C
attached hereto pursuant to which the Company has agreed to provide certain
registration rights with respect to the Securities under the 1933 Act and the
rules and regulations promulgated thereunder, and applicable state securities
laws.

                                   AGREEMENTS

         NOW, THEREFORE, in consideration of their respective promises contained
herein and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged by the parties, the Company and the Buyer hereby
agree as follows:

         1.       PURCHASE AND SALE OF SECURITIES.

         a. Purchase. At the Closing, the Buyer shall purchase from the Company,
and the Company shall sell to the Buyer, 1,250 shares of Preferred Stock and the
Warrants. The purchase price (the "Purchase Price") for the Preferred Stock and
the Warrants purchased by the Buyer shall be $1,250,000.00.

         b. The Closing. Subject to the terms of this Agreement, the date of the
Closing (the "Closing Date") shall be May 22, 2000. The Purchase Price shall be

in the form of Exhibit D attached hereto (the "Escrow Agreement")) on behalf of
the Company within one (1) business day after the execution and delivery of this
Agreement, to be held by the Escrow Agent pending the parties' completion of the
items required pursuant to Sections 6 and 7 hereof. On or before the Closing
Date, the Company shall deliver the original certificate(s) representing the

thereof, with the originals to follow via express courier within one (1)

<PAGE>   3
         c. Form of Payment. Except as hereinafter stated, the Buyer shall pay
the Purchase Price for the Securities purchased at the Closing by wire transfer
of immediately available funds in United States Dollars, to be deposited into
the Escrow Account as defined in the Escrow Agreement, against delivery to the
Escrow Agent of the appropriate number of shares of duly authorized and issued
Preferred Stock and Warrants being purchased by the Buyer hereunder at such
Closing. The Escrow Agent shall be responsible for delivery of the Purchase
Price to the Company and the Preferred Stock and Warrants to the Buyer in
accordance with the terms of the Escrow Agreement and with the instructions of
the said parties. The parties acknowledge that the Buyer has loaned the sum of
US$500,000.00 to the Company in exchange for that eight percent (8%) Promissory
Note executed by the Company as of May 5, 2000, and delivered to the Escrow
Agent on behalf of the Buyer (the "Note"). The parties acknowledge that, if the
transactions contemplated by this Agreement are consummated, then upon the
Closing, the cash portion of the Purchase Price shall be reduced by the amount
of the outstanding principal and accrued but unpaid interest (the "Amount Due")
under the Note on the Closing Date, the Note shall be canceled as of the Closing
Date, and the Amount Due shall be credited to the Buyer as partial delivery and
payment of the Purchase Price.

         2.       BUYER'S REPRESENTATIONS AND WARRANTIES.

         The Buyer understands, agrees with, and represents and warrants to the
Company with respect to its purchase hereunder, that:

         a. Investment Purposes; Compliance With 1933 Act. The Buyer is
purchasing the Securities for its own account for investment only and not with a
view towards, or in connection with, the public sale or distribution thereof,
except pursuant to sales registered under or exempt from the 1933 Act and
applicable state securities laws. The Buyer is not purchasing the Securities for
the purpose of covering short sale positions in the Common Stock established on
or prior to the Closing Date. The Buyer agrees to offer, sell or otherwise
transfer the Securities only (i) in accordance with the terms of this Agreement,
the Certificate of Designations and the Warrants, as applicable, and (ii)
pursuant to registration under the 1933 Act or to an exemption from registration
under the 1933 Act and any other applicable securities laws. The Buyer does not
by its representations contained in this Section 2(a) agree to hold the
Securities for any minimum or other specific term and reserves the right to
dispose of the Securities at any time pursuant to a registration statement or in
accordance with an exemption from registration under the 1933 Act, in all cases
in accordance with applicable state and federal securities laws. The Buyer
understands that it shall be a condition to the issuance of the Conversion
Shares, the Option Shares, the Warrant Shares and the Dividend Shares (if any)
that the Conversion Shares, the Option Shares, the Warrant Shares and the
Dividend Shares (if any) be and are subject to the representations set forth in
this Section 2(a).

         b. Accredited Investor Status. The Buyer is an "accredited investor" as
that term is defined in Rule 501 (a) of Regulation D. The Buyer has such
knowledge and experience in financial and business matters that it is capable of
evaluating the merits and risks of an investment made pursuant to this
Agreement. The Buyer is aware that it may be required to bear the economic risk

                                       -3-
<PAGE>   4
of an investment made pursuant to this Agreement for an indefinite period of
time, and is able to bear such risk for an indefinite period.

         c. Reliance on Exemptions. The Buyer understands the Securities are
being offered and sold to it in reliance on specific exemptions from the
registration requirements of the applicable United States federal and state
securities laws and that the Company is relying upon the truth and accuracy of,
and the Buyer's compliance with, the representations, warranties,
acknowledgments, understandings, agreements and covenants of the Buyer set forth
herein in order to determine the availability of such exemptions and the
eligibility of the Buyer to acquire the Securities.

         d. 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 that have
been requested by the Buyer. The Buyer and its advisors, if any, have been
afforded the opportunity to ask all such questions of the Company as they have
in their discretion deemed advisable. The Buyer understands that its investment
in the Securities involves a high degree of risk. The Buyer has sought such
accounting, legal and tax advice as it has considered necessary to an informed
investment decision with respect to the investment made pursuant to this
Agreement.

         e. No Government Review. The Buyer understands that no United States
federal or state agency or any other government or governmental agency has
approved or made any recommendation or endorsement of the Securities or the
fairness or suitability of the investment in the Securities, nor have such
authorities passed upon or endorsed the merits of the offering of the
Securities.

         f. Transfer or Resale. The Buyer understands that: (i) except as
provided in the Registration Rights Agreement, the Securities have not been and
are not being registered under the 1933 Act or any state securities laws, and
may not be offered for sale, sold, assigned or transferred unless either (a)
subsequently registered thereunder or (b) the Buyer shall have delivered to the
Company an opinion by counsel reasonably satisfactory to the Company, in form,
scope and substance reasonably satisfactory to the Company, to the effect that
the securities to be sold, assigned or transferred may be sold, assigned or
transferred pursuant to an exemption from such registration, (ii) any sale of
such securities made in reliance on Rule 144 (as hereafter defined) may be made
only in accordance with the terms of Rule 144 and further, if Rule 144 is not
applicable, any resale of such securities under circumstances in which the
seller (or the person though whom the sale is made) may be deemed to be an
underwriter (as that term is defined in the 1933 Act) may require compliance
with some other exemption under the 1933 Act or the rules and regulations of the
SEC thereunder and applicable state securities laws, and (iii) neither the
Company nor any other person is under any obligation to register such securities
under the 1933 Act or any state securities laws or to comply with the terms and
conditions of any exemption thereunder (in each case, other than pursuant to
this Agreement or the Registration Rights Agreement).

                                       -4-
<PAGE>   5
         g. Legend. The Buyer understands that the Preferred Stock, the
Warrants, and until such time as the Conversion Shares, the Option Shares, the
Warrant Shares and the Dividend Shares (if any) (collectively, the "Registrable
Securities"), have been registered under the 1933 Act as contemplated by the
Registration Rights Agreement or otherwise may be sold by the Buyer pursuant to
Rule 144 (as amended, or any applicable rule which operates to replace said
Rule) promulgated under the 1933 Act ("Rule 144"), the stock certificates
representing the Registrable Securities will bear a restrictive legend (the
"Legend") in substantially the following form:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE "ACT"), OR APPLICABLE STATE SECURITIES LAWS
(COLLECTIVELY, THE "LAWS"). THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND
MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF
EITHER (I) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE
LAWS, OR (II) AN OPINION OF COUNSEL PROVIDED TO THE ISSUER IN FORM, SUBSTANCE
AND SCOPE REASONABLY ACCEPTABLE TO THE ISSUER TO THE EFFECT THAT REGISTRATION IS
NOT REQUIRED UNDER THE LAWS DUE TO AN AVAILABLE EXCEPTION TO OR EXEMPTION FROM
THE REGISTRATION REQUIREMENTS OF THE LAWS.

         The Legend shall be removed and the Company will issue Common Stock
certificates without the Legend to the holder of the applicable Preferred Stock
or any Registrable Securities upon which the Legend is stamped, in accordance
with Section 5(b).

         h. Authorization; Enforcement. This Agreement, the Registration Rights
Agreement and the Escrow Agreement have been duly and validly authorized,
executed and delivered by the Buyer and are each and collectively valid and
binding agreements of the Buyer enforceable in accordance with their terms,
subject as to enforceability to general principles of equity and to bankruptcy,
insolvency, moratorium, and other similar laws affecting the enforcement of
creditors' rights generally.

         3.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         The Company understands, agrees with, and represents and warrants to
the Buyer that:

         a. Organization and Qualification. The Company is a corporation duly
organized and existing in good standing under the laws of the jurisdiction in
which it is incorporated, except as would not have a Material Adverse Effect (as
defined below), and has the requisite corporate power to own its properties and
to carry on its business as now being conducted. The Company is duly qualified
as a foreign corporation to do business and is in good standing in every
jurisdiction in which the nature of the business conducted by it makes such
qualification necessary and where the failure so to qualify would have a
Material Adverse Effect. "Material Adverse Effect" means any material adverse
effect on the operations, properties or financial condition of the Company taken
as a whole. The Common Stock is eligible to trade and is listed for trading on
the OTC Bulletin Board

                                       -5-
<PAGE>   6
Market. The Company has received no notice, either written or oral, with respect
to the continued eligibility of the Common Stock for such listing, and the
Company has maintained all requirements for the continuation of such listing,
and the Company does not reasonably anticipate, based upon conditions currently
existing and reasonably forecasted that the Common Stock will be delisted from
the OTC Bulletin Board Market for the reasonably foreseeable future. The Company
has complied or will timely comply with all requirements of the National
Association of Securities Dealers and the OTC Bulletin Board Market with respect
to the issuance of the Securities.

         b. Authorization; Enforcement. (i) The Company has the requisite
corporate power and authority to enter into and perform this Agreement, the
Registration Rights Agreement and the Escrow Agreement, to issue and sell the
Preferred Stock and the Registrable Securities in accordance with the terms
hereof, and to perform its obligations under the Certificate of Designations in
accordance with the requirements of the same, (ii) the execution, delivery and
performance of the Company's obligations under this Agreement, the Certificate
of Designations, the Warrants, the Registration Rights Agreement and the Escrow
Agreement by the Company and the consummation by it of the transactions
contemplated hereby and thereby 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, (iii) this Agreement, the
Registration Rights Agreement, the Escrow Agreement and, on the Closing Date,
the Preferred Stock and Warrants sold at the Closing, have been duly and validly
authorized, executed and delivered by the Company, and (iv) this Agreement, the
Preferred Stock (when issued), the Warrants (when issued), the Registration
Rights Agreement and the Escrow Agreement constitute the valid and binding
obligations of the Company enforceable against the Company in accordance with
their respective terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or
similar laws relating to, or affecting, generally, the enforcement of creditors'
rights and remedies or by other equitable principles of general application. The
Company (and its legal counsel) has examined this Agreement and is satisfied in
its sole discretion that, assuming the accuracy of the representations of the
Buyer contained in Section 2 of this Agreement, this Agreement and the
accompanying Exhibits, Schedules and the Addenda, if any, are in accordance with
Regulation D and the 1933 Act and are effective to accomplish the purposes set
forth herein and therein.

         c. Capitalization. As of May 1, 2000, the authorized common stock of
the Company consisted of 50,000,000 shares of Common Stock of which 17,303,758
shares were issued and outstanding. As of May 1, 2000, the authorized preferred
stock of the Company consisted of 10,000,000 preferred shares, of which 1,150
senior convertible preferred shares ("Series A Preferred Shares") were issued

there authorized or outstanding any other classes of preferred stock or other
equity or debt securities other than the Preferred Stock. All of such
outstanding shares of Common Stock and Series A Preferred Shares have been
validly issued and are fully paid and nonassessable. No shares of Common Stock
nor the Series A Preferred Shares are subject to preemptive rights or any other
similar rights or any liens or encumbrances. Except for the Series A Preferred
Shares and the Company's promissory notes issued in connection therewith, the
Securities issued pursuant to this

                                       -6-
<PAGE>   7
Agreement and as disclosed in Schedule 3(c) (attached if applicable), as of the
effective date of this Agreement, (i) there are no outstanding options,
warrants, scrip, rights to subscribe to, calls or commitments of any character
whatsoever relating to, or securities or rights convertible into, any shares of

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 outstanding debt securities, and (iii) 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 1933 Act

Agreement). If requested by the Buyer, the Company has furnished to the Buyer,
and the Buyer acknowledges receipt of same by its signature hereafter, true and
correct copies of the Company's Articles of Incorporation, as amended, as in
effect on the date hereof ("Articles of Incorporation"), and the Company's
Bylaws, as in effect on the date hereof (the "Bylaws").

         d. Issuance of Securities. The Registrable Securities are all duly
authorized and reserved for issuance, and in all cases upon issuance shall be
validly issued, fully paid and non-assessable, free from all taxes, liens and
charges with respect to the issue thereof, and will not be subject to preemptive
rights or other similar rights of stockholders of the Company.

         e. Acknowledgment Regarding Buyer's Purchase of the Securities. The
Company acknowledges and agrees that the Buyer is not acting as financial
advisor to or fiduciary of the Company (or in any similar capacity with respect
to this Agreement or the transactions contemplated hereby), that this Agreement
and the transactions contemplated hereby, and the relationship between the Buyer
and the Company, are and will be considered "arms-length" notwithstanding any
other or prior agreements or nexus between the Buyer and the Company, whether or
not disclosed, and that any statement made by the Buyer, or any of its
representatives or agents, in connection with this Agreement and the
transactions contemplated hereby is not advice or a recommendation, is merely
incidental to the Buyer's purchase of the Securities and has not been relied
upon in any way by the Company, its officers or directors. The Company further
represents to the Buyer that the Company's decision to enter into this Agreement
and the transactions contemplated hereby have been based solely upon an
independent evaluation by the Company, its officers and directors.

         f. No Integrated Offering. Neither the Company, nor any of its
affiliates, nor any person acting on its or their behalf, has directly or
indirectly made any offers or sales of any security or solicited any offers to

consummating the transactions contemplated hereby pursuant to an exemption from
registration under the 1933 Act and specifically in accordance with the
provisions of Regulation D. The transactions contemplated hereby are exempt from
the registration requirements of the 1933 Act, assuming the accuracy of the
representations and warranties contained herein of the Buyer.

         g. No Conflicts. The execution, delivery and performance of this
Agreement by the Company and the consummation by the Company of the transactions
contemplated hereby will not (i) result in a violation of the Articles of
Incorporation or Bylaws or (ii) conflict with, or constitute

                                      -7-
<PAGE>   8
a default (or an event which with notice or lapse of time or both would 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 result in a violation of
any law, rule, regulation, order, judgment or decree (including federal and
state securities laws 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). Except
as set forth in Schedule 3(g) (attached if applicable), neither the Company nor
any of its subsidiaries is in violation of its Articles of Incorporation 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, would put the Company or any of its subsidiaries in
default) under, nor has there occurred any event giving others (with notice or
lapse of time or both) 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, except for possible defaults or rights as
would not, in the aggregate or individually, have a Material Adverse Effect. The
business of the Company and its subsidiaries is not being conducted, and shall
not be conducted so long as the Buyer owns any of the Securities, in violation
of any law, ordinance or regulation of any governmental entity, except for
possible violations which neither singly or in the aggregate would have a
Material Adverse Effect. Except as specifically contemplated by this Agreement
and as required under the 1933 Act and any applicable state securities laws (any
of which exceptions are set forth in Schedule 3(g)), the Company is not required
to obtain any consent, authorization or order of, or make any filing or
registration with, any court or governmental agency (except for such consents,
authorizations or orders as would not have a Material Adverse Effect) in order
for it to execute, deliver or perform any of its obligations under this
Agreement, the Certificate of Designations, the Warrants, the Registration
Rights Agreement or the Escrow Agreement in accordance with the terms hereof and
thereof, or to perform its obligations with respect to the Preferred Stock
exactly as described in the Certificate of Designations (once the Preferred
Stock is issued), and with respect to the Warrants exactly as described in the
Warrants (once issued).

the SEC), the Company has timely filed all reports, schedules, forms, statements
and other documents to be filed by it with the SEC pursuant to the reporting
requirements of the Securities Exchange Act of 1934, as amended (the "1934 Act")

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 material fact or omitted

                                      -8-
<PAGE>   9
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 generally accepted accounting principles,
consistently applied, during the periods involved (except (i) as may be

in the case of unaudited interim statements, to the extent they may exclude
footnotes or may be condensed or summary statements or are otherwise subject to
normal year-end adjustments) and fairly present in all material respects the
financial position of the Company as of the dates thereof and the results of its
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end audit adjustments). No other
information provided by or on behalf of the Company to the Buyer (including the
information referred to in Section 2(d) of this Agreement) contains any untrue
statement of a material fact or omits to state any material fact necessary in
order to make the statements therein, in the light of the circumstance under
which they are or were made, not misleading. Except as set forth in the
financial statements of the Company included in the SEC Documents, the Company
has no material liabilities, contingent or otherwise (to the best of the
knowledge of the Company's Chief Executive Officer, President or any other
senior level officer of the Company (the "Company's Knowledge")), other than (i)
liabilities incurred in the ordinary course of business subsequent to the date
of such financial statements 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, in each case of clause (i) and (ii) next above which, individually
or in the aggregate, are not material to the financial condition, business,
operations, properties, operating results or prospects of the Company. The SEC
Documents contain a complete and accurate list of all written and oral
contracts, agreements, leases or other instruments to which the Company or any
subsidiary is a party or by which the Company or any subsidiary is subject which
are required by the rules and regulations promulgated by the SEC to be so listed
(each a "Contract"). None of the Company, its subsidiaries or, to the best of
the Company's Knowledge, any of the other parties thereto, is in breach or
violation of any Contract, including without limitation any default in payment
under any of the Company's promissory notes issued in connection with the Series
A Preferred Shares, which breach or violation would, or with the lapse of time,
the giving of notice, or both, have a Material Adverse Effect.

         i. Absence of Certain Changes. Except as disclosed in the SEC
Documents, since at least May 1, 1999, there has been no material adverse change
and no material adverse development in the business, properties, operation,
financial condition, results of operations or prospects of the Company. The
Company has not taken any steps, and does not currently have any reasonable
expectation of taking any steps, to seek protection pursuant to any bankruptcy
law nor does the Company have any knowledge that its creditors intend to
initiate involuntary bankruptcy proceedings. The Company shall, at least until
Buyer no longer holds any of the Securities, maintain its corporate existence in
good standing and shall pay all taxes when due except for taxes it reasonably
disputes.

                                      -9-
<PAGE>   10
         j. Absence of Litigation. Except as set forth in Schedule 3(j)
(attached if applicable), there is no action, suit, proceeding, inquiry or
investigation before or by any court, public board or body pending or, to the
best of the Company's Knowledge, threatened against or affecting the Company,
wherein an unfavorable decision, ruling or finding would reasonably be expected
to have a Material Adverse Effect or which would reasonably be expected to
adversely affect the validity or enforceability of, or the authority or ability
of the Company to perform its obligations under, this Agreement or any of the
documents contemplated herein.

         k. Foreign Corrupt Practices. Neither the Company nor any of its
subsidiaries, nor to the best of the Company's Knowledge, any officer, director
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 expense
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 violation of any provision of the U.S. Foreign Corrupt
Practices Act of 1977, as amended; or made any bribe, rebate, payoff, influence
payment, kickback or other unlawful payment to any foreign or domestic
government official or employee.

         l. Brokers; No General Solicitation. The Company has taken no action
that would give rise to any claim by any person for brokerage commissions,
finder's fees or similar payments relating to this Agreement and the
transactions contemplated hereby, other than to Delano Group Securities, L.L.C.
The Company and the Buyer both acknowledge that no other broker or finder was
involved with respect to the transactions contemplated hereby, other than Delano
Group Securities, L.L.C. Neither the Company nor any distributor participating
on the Company's behalf in the transactions contemplated hereby nor any person
acting for the Company, or any such distributor, has conducted any "general
solicitation," as described in Rule 502(c) under Regulation D, with respect to
the Securities being offered hereby.

         m. Acknowledgment of Dilution. The number of Conversion Shares (and
Option Shares) issuable upon conversion of the Preferred Stock (and exercise of
the Option) and the number of Warrant Shares issuable upon exercise of the
Warrant may increase substantially in certain circumstances, including the
circumstance wherein the trading price of the Common Stock declines. The
Company's executive officers and directors have studied and fully understand the
nature of the securities being sold hereunder and recognize they have a
potential dilutive effect. The board of directors of the Company has concluded
in its good faith business judgment that such issuance is in the best interests
of the Company. The Company acknowledges that its obligation to issue Conversion
Shares upon conversion of the Preferred Stock (and Option Shares upon exercise
of the Option, if applicable) and Warrant Shares upon exercise of the Warrants
is binding upon it and enforceable regardless of the dilution that such issuance
may have on the ownership interests of other stockholders.

         n. Eligibility to File Registration Statement. The Company is currently
eligible to file a registration statement with the SEC either on Form SB-1 or
Form SB-2 under the 1933 Act.

                                      -10-
<PAGE>   11
         o. (Intentionally Omitted.)

         p. Non-Disclosure of Non-Public Information. (a) The Company shall in
no event disclose non-public information to the Buyer, advisors to or
representatives of the Buyer unless prior to such disclosure of information the
Company marks such information as "non-public information - confidential" and
provides the Buyer, such advisors and representatives with the opportunity to
accept or refuse to accept such non-public information for review. The Company
may, as a condition to disclosing any non-public information hereunder, require
the Buyer, its advisors and representatives to enter into a confidentiality
agreement in form reasonably satisfactory to the Company and the Buyer.

                  (b) Nothing herein shall require the Company to disclose
non-public information to the Buyer, its advisors or representatives, and the
Company represents that it does not disseminate non-public information to
investors who purchase stock in the Company in a public offering, to money
managers or to securities analysts; provided, however, that notwithstanding
anything herein to the contrary, the Company will, as hereinabove provided,
immediately notify the advisors and representatives of the Buyer and, if any,
underwriters, of any event or the existence of any circumstance (without any
obligation to disclose the specific event or circumstance) of which it becomes
aware, constituting non-public information (whether or not requested of the
Company specifically or generally during the course of due diligence by such
persons or entities), which, if not disclosed in the prospectus included in the
registration statement to be filed pursuant to the Registration Rights
Agreement, would cause such prospectus to include a material misstatement or to
omit a material fact required to be stated therein in order to make the
statements therein, in light of the circumstances in which they were made, not
misleading. Nothing herein shall be construed to mean that such persons or
entities other than the Buyer (without the written consent of the Buyer prior to
disclosure of such information) may not obtain non-public information in the
course of conducting due diligence in accordance with the terms of this
Agreement and nothing herein shall prevent any such persons or entities from
notifying the Company of their opinion that, based upon such due diligence by
such persons or entities, that the registration statement contains an untrue
statement of a material fact or omits a material fact required to be stated in
such registration statement or necessary to make the statements contained
therein, in light of the circumstances in which they were made, not misleading.

         4. COVENANTS.

         a. Best Efforts. Each party shall use its best efforts timely to
satisfy each of the conditions to be satisfied by it as provided in Sections 6
and 7 of this Agreement.

         b. Securities Laws. The Company agrees to timely file a Form D (and any
equivalent form required by applicable state law) with respect to the Securities
if and as required under Regulation D and applicable state securities laws and
to provide a copy thereof to the Buyer promptly after such filing. The Company
shall, on or before the Closing Date, take such action as

                                      -11-
<PAGE>   12
is necessary to sell the Securities being sold to the Buyer on each such date
under applicable securities laws of the United States and the relevant state(s),
and shall if specifically so requested provide evidence of any such action so
taken to the Buyer on or prior to the Closing Date.

         c. Reporting Status. So long as the Buyer beneficially owns any of the
Securities, the Company shall 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 hereunder would permit such termination.

         d. Use of Proceeds. The Company will use the proceeds from the sale of
the Securities for the deployment of the IPVoice Network, and for administrative
overhead and general working capital needs.

         e. Financial Information. Until such time as the Buyer no longer
beneficially owns Securities, the Company agrees to send the following reports
to the Buyer: (i) after filing with the SEC, a copy of each of its Annual
Reports, its Quarterly Reports, and any reports filed on Form 8-K; and (ii) as
soon as reasonably practicable after release thereof, copies of all press
releases issued by the Company or any of its subsidiaries.

         f. 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 the issuance of all of the Conversion
Shares, the Option Shares, the Warrant Shares and the Dividend Shares (if any).
Prior to complete conversion of the Preferred Stock, exercise of the Option and
exercise of the Warrants, the Company shall not reduce the number of shares of
Common Stock reserved for issuance hereunder without the written consent of the
Buyer except for a reduction proportionate to a reverse stock split effected for
a business purpose other than affecting the requirements of this Section, which
reverse stock split affects all shares of Common Stock equally.

         g. Listing. Upon the Closing, the Company shall promptly secure the
listing of the Common Stock underlying the Preferred Stock and the 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 shall maintain, so long as any other shares of Common Stock shall
be so listed, such listing of shares of Registrable Securities from time to time
issued under the terms of this Agreement and the Registration Rights Agreement.
The Company shall at all times comply in all respects with the Company's
reporting, filing and other obligations under the by-laws or rules of the
National Association of Securities Dealers and the OTC Bulletin Board Market (or
such other national securities exchange or market on which the Common Stock may
then be listed, as applicable).

         h. Prospectus Delivery Requirement; Escrow of Registrable Securities.
The Buyer understands that the 1933 Act requires delivery of a prospectus
relating to the Common Stock in connection with any sale thereof pursuant to a
registration statement under the 1933 Act covering any resale by the Buyer of
the Common Stock being sold, and the Buyer shall comply with any

                                      -12-
<PAGE>   13
applicable prospectus delivery requirements of the 1933 Act in connection with
any such sale. The Company shall have the unequivocal right to rely upon the
Buyer's representation and covenant to deliver a prospectus as required by
applicable law or regulation contained in this Section 4(h), and thus, with
respect to any resales by the Buyer pursuant to a registration statement of
Common Stock (including Option Shares) issued to the Buyer upon conversion of
the Preferred Stock (or in payment of dividends on the Preferred Stock), upon
exercise of the Option or upon exercise of the Warrants, such Common Stock shall
not contain a restrictive legend of any kind. The Buyer will indemnify and hold
harmless the Company and its transfer agent for any loss, cost or expense
(including reasonable attorney's fees) incurred by such parties as a result of
improper actions taken by the Buyer in response to the Company's and the
transfer agent's compliance with the provisions of this Section 4(h), including
without limitation the sales of such Common Stock without delivery of a
prospectus as required by applicable law or regulation. The Company agrees that,
upon effectiveness of the Registration Statement, and from time to time
thereafter as reasonably requested by the Buyer, the Company shall deliver or
cause the Company's transfer agent to deliver to the Escrow Agent one or more
stock certificates representing the number of shares of registered Common Stock
into which the Registrable Securities might then reasonably be convertible or
exercisable (as applicable) (collectively, the "Escrow Shares"). Such
certificate(s) shall not contain a restrictive legend of any kind. The Escrow
Agent shall hold the Escrow Shares in trust, in certificate form or in a
brokerage account as deemed appropriate by the Escrow Agent. Upon a conversion
of Preferred Stock (and/or exercise of the Option), the Buyer shall deliver a
copy of its conversion notice to the Escrow Agent, and to the extent that the
Escrow Agent has sufficient Escrow Shares, the Escrow Agent shall release Escrow
Shares to the Buyer to satisfy such conversion or exercise. The Escrow Agreement
describes in detail the duties of the Escrow Agent with respect to the
provisions of this Section 4(h).

         i. Intentional Acts or Omissions. Neither party shall intentionally
perform any act that if performed, or omit to perform any act that if omitted to
be performed, would prevent or excuse the performance of this Agreement or any
of the transactions contemplated hereby.

         j. No Shorting. As a material inducement for the Company to enter into
this Agreement, the Buyer represents that it has not as of the date hereof, and
covenants on behalf of itself and its affiliates that neither Buyer nor any
affiliate of Buyer will at any time in which the Buyer or any affiliate of the
Buyer beneficially owns any of the Securities, engage in any short sales of, or
hedging or arbitrage transactions with respect to, the Common Stock, or buy
"put" options or similar instruments with respect to the Common Stock. The
Company acknowledges that a sale of Conversion Shares, Option Shares or Warrant
Shares on the date a conversion of the Preferred Stock (or exercise notice for
the Warrants) is made, even if such sale is made prior to delivery of the notice
of conversion with respect to such Conversion Shares (or exercise notice with
respect to such Warrant Shares), is not a "short sale" for purposes of this
Section 4(j).

         k. Expenses. The Company agrees to pay to or at the direction of the
Buyer the sum of $3,000.00 at the Closing as reimbursement for the attorney's
fees and expenses of the Buyer incurred by it in connection with the
transactions contemplated by this Agreement.

                                      -13-
<PAGE>   14
         l. No Additional Issuance of Series B Preferred Stock. The Company
agrees that it will not issue Preferred Stock to any person other than to the
Buyer or to the other buyer concurrently executing agreements of like tenor with
this Agreement (the "Other Buyer") in respect of the transactions contemplated
herein and therein.

         m. Restriction on Below Market Issuance of Securities. Until the date
which is the earlier of twelve (12) months from the Closing Date or the date the
Preferred Stock has been redeemed or converted in full, the Company shall not
issue or agree to issue (other than (i) to the Buyer and to the Other Buyer
pursuant to the transactions contemplated herein, (ii) pursuant to any employee
stock option plan or employee stock purchase plan of the Company established
during the term of this restriction for a legitimate business purpose and not to
avoid the restrictions imposed in this Section 4(m), (iii) pursuant to any
existing security, option, warrant, scrip, call or commitment or right in each
case as disclosed on Schedule 3(c) hereof, or (iv) with the consent of the Buyer
and the Other Buyer, not to be unreasonably withheld) any equity securities of
the Company (or any security convertible into or exercisable or exchangeable,
directly or indirectly, for equity securities of the Company) or debt securities
of the Company if such securities are issued at a price (or provide for a
conversion, exercise or exchange price) which may be less than the current
market price for the Common Stock on the date of issuance (in the case of Common
Stock) or the date of conversion, exercise or exchange (in the case of
securities convertible into or exercisable or exchangeable, directly or
indirectly, for Common Stock). In the event the Company seeks to offer such
securities as permitted in subsection 4(m)(iv) of this Section, the Company
shall first offer to the Buyer and to the Other Buyer, pro rata, the opportunity
to purchase such securities on the same terms and conditions as proposed by the
Company (the "First Offer"). The Buyer shall have ten (10) days to advise the
Company in writing that it accepts its pro rata share of the First Offer. If the
Buyer does not so advise the Company, the Company shall be free, for a period of
sixty (60) days, to issue such securities as proposed to such other party, after
which sixty (60) day period the restrictions contained in this Section 4(m)
shall apply as if the Buyer had not given its consent and the First Offer had
not been made to the Buyer. Except as provided with respect to the transactions
contemplated herein (including also the issuance of certain warrants to Delano
Group Securities, L.L.C.) and with respect to the Securities issued and sold to
the Other Buyer, and in subsections (i), (ii), (iii), or (iv) above of this
Section 4(m), until such time as the Preferred Stock has been paid or converted
in full, the Company shall not grant any additional so-called "registration
rights."

         5. LEGEND AND TRANSFER INSTRUCTIONS.

         a. Transfer Agent Instructions. The Company shall instruct its transfer
agent to issue certificates, registered in the name of the Buyer or its
permitted nominee, for the Conversion Shares, the Option Shares, the Warrant
Shares and the Dividend Shares (if any) in accordance with the terms of the
applicable Preferred Stock and Warrants and in such amounts as are set forth in
the Certificate of Designation and Warrants, respectively, upon conversion of
the Preferred Stock or exercise of the Warrants (as applicable). All such
certificates shall bear the restrictive legend specified in Section 2(g) of this
Agreement only to the extent required by applicable law and as specified in this
Agreement and the Exhibits and Addenda hereto, and with consideration to Section
4(h) hereof. The

                                      -14-
<PAGE>   15
Company warrants that no instruction other than such instructions referred to in
this Section 5, and stop transfer instructions to give effect to Section 2(f)
hereof in the case of the Conversion Shares, the Option Shares, the Warrant
Shares and the Dividend Shares (if any) prior to the registration of same under
the 1933 Act, will be given by the Company to its transfer agent and that the
Conversion Shares, the Option Shares, the Warrant Shares and the Dividend Shares
(if any) shall otherwise be freely transferable on the books and records of the
Company as and to the extent permitted by applicable law and provided by this
Agreement, the Warrants and the Registration Rights Agreement. Nothing in this
Section shall affect in any way the Buyer's obligations and agreement to comply
with all applicable securities laws upon resale of the Conversion Shares, the
Option Shares, the Warrant Shares and/or the Dividend Shares (if any). If the
Buyer (x) provides the Company with an opinion of counsel reasonably
satisfactory to Company that registration by the Buyer of the Preferred Stock,
the Warrants, the Warrant Shares, the Conversion Shares, the Option Shares
and/or the Dividend Shares (if any) is not required under the 1933 Act and that
resale is otherwise permitted under applicable securities laws, or (y) transfers
Securities to an affiliate which is an accredited investor (in accordance with
the provisions of this Agreement) or in compliance with Rule 144, then in either
instance the Company shall permit the said transfer, and if applicable promptly
(and in all events within two (2) trading days) instruct its transfer agent to
issue one or more certificates in such name and in such denominations as
specified by the Buyer.

         b. Removal of Legends. The Legend shall be removed and the Company
shall issue a certificate without such Legend to the holder of any Security upon
which it is stamped, and a certificate for a security shall be originally issued
without the Legend, if, unless otherwise required by state securities laws, (x)
the sale of such Security is registered under the 1933 Act, or (y) such holder
provides the Company with an opinion by counsel reasonably satisfactory to the
Company, that is in form, substance and scope reasonably satisfactory to the
Company, to the effect that a public sale or transfer of such Security may be
made without registration under the 1933 Act or (z) such holder provides the
Company with assurances reasonably satisfactory to the Company and its counsel,
that such Security can be sold pursuant to Rule 144. The Buyer agrees that its
sale of all Securities, including those represented by a certificate(s) from
which the Legend has been removed, or which were originally issued without the
Legend, shall be made only pursuant to an effective registration statement (and
to deliver a prospectus in connection with such sale) or in compliance with an
exemption from the registration requirements of the 1933 Act. In the event the
Legend is removed from any Security or any Security is issued without the Legend
and thereafter the effectiveness of a registration statement covering the sales
of such Security is suspended or the Company determines that a supplement or
amendment thereto is required by applicable securities laws, then upon
reasonable advance notice to the holder of such Security, the Company shall be
entitled to require that the Legend be placed upon any such Security which
cannot then be sold pursuant to an effective registration statement or Rule 144
or with respect to which the opinion referred to in clause (y) next above has
not been rendered, which Legend shall be removed when such Security may be sold
pursuant to an effective registration statement or Rule 144 (or such holder
provides the opinion with respect thereto described in clause (y) next above.

                                      -15-
<PAGE>   16
         c. Conversion of Preferred Stock. The Buyer shall have the right to
convert the Preferred Stock sold hereunder and to exercise the Option by
delivering via facsimile an executed and completed Notice of Conversion (as
defined in the Certificate of Designations) to the Company and delivering within
two (2) business days thereafter the original Notice of Conversion and the
original Preferred Stock certificate being converted (but only at such time as
such original Preferred Stock certificate being converted is converted in full
into Common Stock, unless otherwise specifically requested by the Company) by
express courier to the Company. Each date on which a Notice of Conversion is
faxed to the Company in accordance with the provisions hereof shall be deemed a
"Conversion Date." The Company will transmit the certificates (each a
"Certificate" and collectively the "Certificates") representing the shares of
Common Stock issuable upon conversion of any Preferred Stock, including also any
applicable Option Shares and Dividend Shares (along with a replacement
certificate representing the number of preferred shares not so converted, if
applicable) to the Buyer via express courier, within three (3) business days
after the relevant Conversion Date (with respect to each conversion, the
"Deadline"); however, the preceding clause shall not apply to the extent that
the Escrow Agent is (by virtue of the fact that the Escrow Agent is then in
possession of a sufficient number of shares of Common Stock) able to deliver
Common Stock to satisfy such conversion or exercise in accordance with Section
4(h) above and the applicable provisions of the Escrow Agreement. Time is of the
essence with respect to the requirements of the first clause of the immediately
preceding sentence.

         d. Injunctive Relief for Breach. The Company acknowledges that a breach
of its obligations under Sections 5(a), 5(b) and 5(c) above will cause
irreparable harm to the Buyer by vitiating the intent and purpose of the
transactions contemplated hereby. Accordingly the Company agrees that the remedy
at law for a breach of its obligations under such Sections would be inadequate
and agrees, in the event of a breach or threatened breach by the Company of the
provisions of such Sections, the Buyer shall be entitled, in addition to all
other remedies at law or in equity, to an injunction restraining any breach and
requiring immediate issuance and transfer, without the necessity of showing
economic loss and without any bond or other security being required.

         e. Liquidated Damages for Non-Delivery of Certificates. In addition to
the provisions of Section 5(d) above, the Company understands and agrees that a
delay in the issuance of any of the Certificates beyond the Deadline will result
in substantial economic loss and other damages to the Buyer. As partial
compensation to the Buyer for such loss, the Company agrees to pay liquidated
damages (which the Company acknowledges is not a penalty) to the Buyer for
issuance and delivery of any Certificate after the Deadline, in accordance with
the following schedule (where "No. Business Days Late" is defined as the number
of business days beyond three (3) business days from the date of delivery by the
Buyer to the Company of a facsimile Notice of Conversion (or, if later, from the
date on which all other necessary documentation duly executed and in proper form
required for conversion of Preferred Stock as described in this Agreement,
including the original Notice of Conversion, all in accordance with this
Agreement only if such necessary documentation has not been delivered to the
Company within the two (2) business day period after the facsimile delivery to
the Company of the Notice of Conversion as required in this Agreement)):

</TABLE>

         The Company shall pay the Buyer any liquidated damages incurred as
called for under this Section 5(e) by certified or cashier's check upon the
earlier of (i) issuance of the relevant Certificate(s) to the Buyer or (ii) each
monthly anniversary of the receipt by the Company of the Buyer's Notice of
Conversion. Nothing herein shall limit the Buyer's right to pursue actual
damages for the Company's failure to issue and deliver all Certificates to the
Buyer in accordance with the terms of this Agreement or for breach by the
Company of this Agreement. Notwithstanding anything in this Section 5(e) to the
contrary, the Company shall not be responsible for liquidated damages as
described in this Section 5(e) if a delay past a Deadline in delivery of Common
Stock to the Buyer upon a conversion or exercise is solely due to the action (or
omission to act) of the Escrow Agent (that is, if the Escrow Agent has in its
possession a sufficient number of non-legended Escrow Shares to effect a
conversion of Preferred Stock and/or an exercise of the Option, and there is no
Company-caused delay involved in delivery by the Escrow Agent of the requisite

If to the Buyer, at the address on the signature page of this Agreement. Each
party shall provide written 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 respective successors and assigns.
Neither the Company nor the Buyer shall assign this Agreement or any rights or
obligations hereunder without the prior written consent of the other (which
consent shall not be unreasonably withheld), and in any event any assignee of
the Buyer shall be an accredited investor (as defined in Regulation D), in the
written opinion of counsel who is reasonably satisfactory to the Company and in
form, substance and scope reasonably satisfactory to the Company.
Notwithstanding the foregoing, if applicable, any of the entities constituting
the Buyer (if greater than one (1) entity) may assign its rights hereunder to
any of its "affiliates," as that term is defined under the 1934 Act, without the
consent of the Company; provided, however, that any such assignment shall not
release such assigning entity from its obligations hereunder unless such
obligations are assumed by such affiliate and the Company has prior to such
assignment and assumption consented in writing to the same; and no such
assignment shall be made unless it is made in accordance with any applicable
securities laws of any applicable jurisdiction. Any request for an assignment
made hereunder by the Buyer shall be accompanied by a legal opinion in form,
substance and scope reasonably satisfactory to the Company, that such assignment
is proper under applicable law. Notwithstanding anything herein to the contrary,
Buyer may pledge the Securities as collateral for a bona fide loan pursuant to a
security agreement with a third party lender, and such pledge shall not be
considered an assignment in violation of this Agreement so long as it is made in
compliance with all applicable law.

         h. No Third Party Beneficiaries. This Agreement is intended for the
benefit of the parties hereto, any other buyer who execute an Agreement of like
tenor with this Agreement, 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. Unless this Agreement is terminated under Section 8(1),
the representations and warranties of the Company and the Buyer contained in
Sections 2 and 3 and the agreements and

                                      -21-
<PAGE>   22
covenants set forth in Sections 4, 5 and 8 shall survive the Closing of the
purchase and sale of Securities purchased and sold hereby.

         j. Publicity. The Company and the Buyer shall have the right to review
before issuance by the other, any press releases or any other public statements
with respect to the transactions contemplated hereby; provided, however, that
the Company shall be entitled, without prior consultation with or approval of
the Buyer, to make any press release or other public disclosure with respect to
such transactions as is required by applicable law and regulations.

         k. Further Assurance. 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. Termination. In the event that the Closing shall not have occurred
on or before ten (10) business days from the date hereof, this Agreement shall
terminate at the close of business on such date. Neither party may unilaterally
terminate this Agreement after the Closing for any reason other than a material
breach of this Agreement by the non-breaching party. Such termination shall not
be the sole remedy for a breach of this Agreement by the non-breaching party,
and each party shall retain all of its rights hereunder at law or in equity.
Notwithstanding anything herein to the contrary, a party whose breach of a
covenant or representation and warranty or failure to satisfy a condition
prevented the Closing shall not be entitled to terminate this Agreement.

         m. Remedies. No provision of this Agreement providing for any specific
remedy to a party shall be construed to limit such party to the specific remedy
described, and any other remedy that would otherwise be available to such party
at law or in equity shall be so available. Nothing in this Agreement shall limit
any rights a party may have with any applicable federal or state securities laws
with respect to the transactions contemplated hereby.

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

                                  SCHEDULE 3(c)

     WARRANTS, REGISTRATION RIGHTS, DEBT SECURITIES AND OTHER EQUITY RIGHTS

         See Attached Capitalization Chart attached hereto.

         1. Warrants for common stock with piggyback registration rights in
connection with Units sold in February 1999 offering. If all the warrants were
to be exercised, a total of 862,500 shares of common stock would be issued at an
exercise price of $.9875 per share. As of the date of this Agreement, warrants
for 75,000 shares have been exercised. The Company anticipates that more than
half of these warrants will be surrendered pursuant to the Tender Offer that was
commenced on April 20 and will terminate on May 19. To the extent that warrants
are not surrendered and are exercised, the holders of the common stock received
upon exercise have the right. "at any time that the Company proposes to file a
Company registration statement on Form S-1 or other appropriate registration
form (excluding Form 10SB) under the Act (the "Registration Statement"), for its
own account," to request inclusion of those shares in the registration. The
right is subject to typical exceptions.

         2. Equity to be issued pursuant to Executive Stock Option Plan and 2000
Executive Incentive Plan. Between the two plans, the Company has authorized
issuance of up to 1,300,000 shares of common stock. To date, no options have
been granted under either plan. The Company has currently committed to issue
230,00 options to various employees.

         3. International Investment Partners ("IIP") services agreement
granting a Warrant for 5% of the Company's common stock with antidilution
rights, which are still subject to 3.88% antidilution rights. Warrants issuable
at $1.00 per share. IIP has orally agreed to surrender this Warrant and certain
other claims and rights in exchange for 500,000 shares of the Company's common
stock. A written amendment to the IIP agreement is being prepared to memorialize
this change.

         4. Services Agreement with Netgenie.com, Inc. for 250,000 shares of
common stock and warrants to purchase another 450,000 common shares at $2,50 per
shares, all conditioned upon performance. The Company believes that these rights
expired December 31, 1999 without performance by Netgenie.com.

         5. Investor Communications Group/Corporate Imaging received rights for
100,000 shares in the form of warrants exercisable at $2.00 per share over a
two-year period from the date of issuance with piggyback registration rights.
This agreement has been terminated, but the Warrants may still be outstanding.

         6. In connection with the Share Exchange Agreement with SATLINK 3000,
Inc. d/b/a Independent Network Services ("INS"), in approximately April 1999,
the Company agreed to exchange 250,000 of its redeemable convertible preferred
stock for all of the outstanding capital stock of INS. The redeemable preferred
stock was to be converted on a 1 for 1 basis after one year subject to a
redemption right at $2.00 per share. The Company also entered into an Employment
Agreement with Peter Stazzone, the President of INS, granting him 50,000 shares
of redeemable convertible preferred stock as well as 200,000 shares of common
stock and another 100,000 shares of common stock subject to certain conditions.
The Company voided the agreement but has been sued by the shareholders of INS
and Peter Stazzone. The current outcome is unknown.

         7. Letter Agreement with McGinn Smith for 10,000 shares of common stock
if they provide an introduction to appropriate funding for the Company. They
have not presently earned the shares.

                                      -24-
<PAGE>   25
         8. Promissory Notes in connection with the February 1999 private
offering for Units. A total of 46 notes representing $1,145,400 principal amount
are currently outstanding. The Company anticipates that more than half the notes
will be surrendered in connection with the pending tender offer that commenced
on April 20 and expires on May 19. Any remaining notes, or new notes issued in
substitution for the outstanding notes, will be finally due in the spring of
2002.

         9. Senior Convertible Preferred Stock in connection with the Units sold
in February 1999 offering. Currently 1,150 shares are issued and outstanding.
The Company anticipates that a majority of these shares will be surrendered in
connection with the tender offer that commenced on April 20 and expires on May
19.

         10. The Company has committed to issue 100,000 shares of common stock
to various consultants for services rendered.

                                  SCHEDULE 3(g)

                                    CONFLICTS

         The Company failed to attain certain projections and violated certain
representations made to investors in connection with the Units sold in February
1999 offering. The Company views these as technical violations and no action has
been taken by any shareholder.

         In April 1999, the Company entered into a share exchange agreement with
SATLINK 3000, Inc. d/b/a Independent Network Services, a Nevada corporation
formed in April, 1998, ("INS") whereby the Company exchanged 250,000 shares of
its Redeemable Convertible Preferred Stock valued at $500,000 for all of the
outstanding capital stock of INS. Such Redeemable Convertible Preferred stock
contains 1 for 1 conversion rights after one (1) year and is redeemable at $2.00
per share. The President of INS, Peter M. Stazzone, remained with the Company as
the President of the subsidiary. At the time of the exchange Mr. Stazzone became
Secretary, Treasurer and Chief Financial Officer of the Company under an
employment agreement. Also at the time of the exchange, Mr. Stazzone received
50,000 shares of the Redeemable Convertible Preferred Stock of the Company.
Pursuant to the Employment Agreement, Mr. Stazzone received 200,000 shares of
the Company's Restricted Common Stock, a stock bonus of 100,000 shares of the
Restricted Common Stock deemed earned on the date of the Share Exchange
Agreement, but to be delivered on the earlier of (i) the first anniversary date
or (ii) Mr. Stazzone's termination and options to purchase an additional 200,000
shares of the restricted Common Stock of the Company exercisable for a period of
three (3) years at an exercise price of $1.00 per share. It was represented that
INS had acquired certain assets, including the rights to INS' name, from the
Bankruptcy Court in the Chapter 11 filing on behalf of Telsave Corporation
("Telsave"). Mr. Stazzone was the Chief Financial Officer of Telsave at the time
the bankruptcy was filed and the Bankruptcy Court was provided with disclosure
of his involvement with INS prior to the Court's approval of the sale of certain
Telsave assets to INS. In June 1998, Mr. Stazzone was loaned $100,000 by INS
which loan bears no interest and has no stated repayment terms. At the time of
the acquisition of INS, the Company believed that it was acquiring the rights to
the carrier identification code 10-10-460 ("CIC Code"). The purchase price was
based in part upon an appraisal of the value of the CIC Code which is loaded in
approximately 60% of the domestic market. However, during the course of the
audit, it was discovered that clear title may not have passed to INS and
subsequently the Company as the owner of INS. Therefore, the Board resolved
that, in the event clear title had not passed to the Company, it would be in the
best interest of the shareholders to unwind the transaction. The Company sought
a legal opinion on the status of such title and just prior to filing Form 10SB
discovered that there was no clear link between the ownership of the CIC Code
and INS. Therefore the Company voted to unwind the transaction ab initio, to
rescind the issuances made under the acquisition and the employment agreements
and to terminate Mr. Stazzone's employment. Mr. Stazzone and INS have instituted
suit against the Company. For such offering, the Company relied upon Section
4(2) of the Act and Rule 506, Section 14-4-126(f) of the Arizona Code and
Section 90.530(11) of the Nevada Code.

         In April 1999, the Company entered into a share exchange agreement with
SATLINK 3000, Inc. d/b/a Independent Network Services, a Nevada corporation
formed in April, 1998, ("INS") whereby the Company exchanged 250,000 shares of
its Redeemable Convertible Preferred Stock valued at $500,000 for all of the
outstanding capital stock of INS. Such Redeemable Convertible Preferred stock
contains 1 for 1 conversion rights after one (1) year and is redeemable at $2.00
per share. The President of INS, Peter M. Stazzone, remained with the Company as
the President of the subsidiary. At the time of the exchange Mr. Stazzone became
Secretary, Treasurer and Chief Financial Officer of the Company under an
employment agreement. Also at the time of the exchange, Mr. Stazzone received
50,000 shares of the Redeemable Convertible Preferred Stock of the Company.
Pursuant to the Employment Agreement, Mr. Stazzone received 200,000 shares of
the Company's Restricted Common Stock, a stock bonus of 100,000 shares of the
Restricted Common Stock deemed earned on the date of the Share Exchange
Agreement, but to be delivered on the earlier of (i) the first anniversary date
or (ii) Mr. Stazzone's termination and options to purchase an additional 200,000
shares of the restricted Common Stock of the Company exercisable for a period of
three (3) years at an exercise price of $1.00 per share. It was represented that
INS had acquired certain assets, including the rights to INS' name, from the
Bankruptcy Court in the Chapter 11 filing on behalf of Telsave Corporation
("Telsave"). Mr. Stazzone was the Chief Financial Officer of Telsave at the time
the bankruptcy was filed and the Bankruptcy Court was provided with disclosure
of his involvement with INS prior to the Court's approval of the sale of certain
Telsave assets to INS. In June 1998, Mr. Stazzone was loaned $100,000 by INS
which loan bears no interest and has no stated repayment terms. At the time of
the acquisition of INS, the Company believed that it was acquiring the rights to
the carrier identification code 10-10-460 ("CIC Code"). The purchase price was
based in part upon an appraisal of the value of the CIC Code which is loaded in
approximately 60% of the domestic market. However, during the course of the
audit, it was discovered that clear title may not have passed to INS and
subsequently the Company as the owner of INS. Therefore, the Board resolved
that, in the event clear title had not passed to the Company, it would be in the
best interest of the shareholders to unwind the transaction. The Company sought
a legal opinion on the status of such title and just prior to filing Form 10SB
discovered that there was no clear link between the ownership of the CIC Code
and INS. Therefore the Company voted to unwind the transaction ab initio, to
rescind the issuances made under the acquisition and the employment agreements
and to terminate Mr. Stazzone's employment. Mr. Stazzone and INS have instituted
suit against the Company. For such offering, the Company relied upon Section
4(2) of the Act and Rule 506, Section 14-4-126(f) of the Arizona Code and
Section 90.530(11) of the Nevada Code.

                                   EXHIBIT A

    CERTIFICATE OF DESIGNATION OF THE RELATIVE RIGHTS AND PREFERENCES OF THE
                      SERIES B CONVERTIBLE PREFERRED STOCK
                                       OF
                                IPVOICE.COM, INC.

It is certified that:

A. The name of the corporation is IPVoice.Com, Inc., a Nevada corporation
(hereinafter the "Company").

B. The certificate of incorporation of the Company, as amended, authorizes the
issuance of Ten Million (10,000,000) shares of Preferred Stock, $.001 par value
per share, and expressly vests in the Board of Directors of the Company the
authority provided therein to issue all of said shares in one or more series and
by resolution or resolutions to establish the designation and number and to fix
the relative rights and preferences of each series to be issued.

C. The Board of Directors of the Company, pursuant to the authority expressly
vested in it, has adopted the following resolutions creating a class of Series B
Preferred Stock:

         RESOLVED, that a portion of the Ten Million (10,000,000) authorized
shares of Preferred Stock of the Company shall be designated as a separate
series possessing the rights and preferences set forth below:

         1. Designation and Amount. The shares of such series shall have a par
value of $.001 per share and shall be designated as "Series B Preferred Stock"
(the "Series B Preferred Stock") and the number of shares constituting the
Series B Preferred Stock shall be up to 7,500. The Series B Preferred Stock
shall be offered for sale at a purchase price of $1,000 per share (the "Purchase
Price").

         2. Dividends. The holders of the outstanding shares of Series B
Preferred Stock shall be entitled to receive, when, as and if declared by the
Board of Directors, out of funds legally available therefor, dividends at an
annual rate of seven and one half percent of the Purchase Price. Such dividends
shall be deemed to accrue on the Series B Preferred Stock and be cumulative,
whether or not there are profits, surplus or other funds of the Company legally
available for the payment of dividends. All dividends declared upon the Series B
Preferred Stock shall be declared pro rata per share. If there shall not have
been a sum sufficient for the payment therefor set apart, the deficiency shall
first be paid before any dividend or other distribution shall be paid or
declared and set apart with respect to any other class of the Company's capital
stock, now or hereafter outstanding. All accrued cash dividends shall be
immediately due and payable on the date such shares of Series B Preferred Stock
are converted into shares of Common Stock, par value $.001 per share ("Common

                                      -1-
<PAGE>   30
Stock") in accordance with Section 5 hereof, or are redeemed in accordance with
Section 6 hereof. Dividends may be paid in cash or additional shares of Common
Stock of the Company, as may be determined, from time to time, in the sole
discretion of the Board of Directors. The Company shall not be required to pay
any dividends on the outstanding shares of the Series B Preferred Stock prior to
the Conversion Date and/or Redemption Date (as defined below) for such shares.

                  For purposes of this Certificate, unless the context otherwise
requires, "distribution" shall mean the transfer of cash or property without
consideration, whether by way of dividend or otherwise, payable other than in
shares of Common Stock or other equity securities of the Company, or the
purchase or redemption of shares of Common Stock or other equity securities of
the Company (other than redemptions set forth in Section 6 below or repurchases
of Common Stock or other equity securities held by employees or consultants of
the Company upon termination of their employment or services pursuant to
agreements providing for such repurchase) for cash or property payable other
than in shares of Common Stock or other equity securities of the Company.

         3. Liquidation, Dissolution or Winding Up

                  (a) Treatment at Liquidation, Dissolution or Winding Up. In
the event of any liquidation, dissolution or winding up of the Company, whether
voluntary or involuntary, before any distribution may be made with respect to
Common Stock or any other series of capital stock, holders of each share of
Series B Preferred Stock shall be entitled to be paid out of the assets of the
Company available for distribution to holders of the Company's capital stock of
all classes, whether such assets are capital, surplus, or capital earnings, such
amount equal to the Purchase Price plus all accrued cash dividends
(collectively, the "Liquidation Amount").

                  (b) If the assets of the Company available for distribution to
its shareholders shall be insufficient to pay the holders of shares of Series B
Preferred Stock the full amount of the Liquidation Amount to which they shall be
entitled, the holders of shares of Series B Preferred Stock shall share ratably
in any distribution of assets according to the amounts which would be payable
with respect to the shares of Series B Preferred Stock held by them upon such
distribution if all amounts payable on or which respect to said shares were paid
in full.

                  (c) In the event the holders cannot be located by the Company,
funds necessary for such payment shall be set aside by the Company in trust for
the account of holders of the Series B Preferred Stock so as to be available for
such payments. After payment of the Liquidation Amount shall have been made in
full (including funds held in trust pursuant to the preceding sentence), to the
holders of the Series B Preferred Stock, the holders of the Series B Preferred
Stock shall be entitled to no further participation in the distribution of the
assets of the Company, and the remaining assets of the Company legally available
for distribution to its shareholders shall be distributed among the holders of
other classes of securities of the Company in accordance with their respective
terms.

                  (d) The holders of Series B Preferred Stock shall have no
priority or preference with respect to distributions made by the Company in
connection with the repurchase of shares of Common Stock issued to or held by
employees, directors or consultants upon termination of their

                                      -2-
<PAGE>   31
employment or services pursuant to agreements providing for the right of said
repurchase between the Company and such persons.

         4. Voting Rights. Except as otherwise required by law, and except as
set forth in Section 8 of this Certificate, the holders of Series B Preferred
Stock shall not be entitled to vote upon any matter relating to the business or
affairs of the Company or for any other purpose.

         5. Conversion Rights for the Series B Preferred Stock; Optional
Purchase of Additional Shares of Common Stock. The holders of Series B Preferred
Stock shall have conversion rights as follows ("Conversion Rights"):

                  (a) Right to Convert. No shares of Series B Preferred Stock
may be converted prior to the date (the "First Conversion Date") which is the
earlier of (i) the effective date of the registration statement covering the
resale of the shares of Common Stock issuable upon conversion of the Series B
Preferred Stock, and (ii) the one hundred eightieth day after the closing date
(the "Closing Date") of the issuance of the Series B Preferred Stock.

                  (b) Conversion Rate. Each share of Series B Preferred Stock
may be converted into the number of fully-paid and non-assessable shares of
Common Stock of the Company calculated in accordance with the following formula
("Conversion Rate"):

         The number of shares issuable upon conversion of one share of Series B
Preferred Stock shall be determined by dividing the Purchase Price by the
Conversion Price, where:

                           (i) The Purchase Price is defined in Section 1
hereof; provided that, for purposes of this Section 5(b), in the event that the
Company elects to pay the dividends in additional shares of Common Stock which
have been registered under the Securities Act of 1933, as amended, the dividend
amount per share will be added to the Purchase Price for each such share of
Series B Preferred Stock;

                           (ii) the Conversion Price equals the lesser of (x)
one hundred ten percent (110%) of the lowest of the Closing Bid Prices (defined
below) for the Common Stock for the five (5) trading days prior to the date of
issuance of the Series B Preferred Stock being converted (the "Maximum Price"),
or (y) seventy five percent (75%) (the "Conversion Percentage") of the average
of the three (3) lowest Closing Bid Prices for the Common Stock for the thirty
(30) consecutive trading days immediately preceding the Conversion Date (as
herein defined), as reported on the National Association of Securities Dealers
OTC Bulletin Board Market (or on such other national securities exchange or
market as the Common Stock may trade at such time); notwithstanding anything in
this paragraph to the contrary, if the registration statement covering the
resale of the shares of Common Stock issuable upon conversion of the Series B
Preferred Stock has not been declared effective within 180 days (the "Due Date")
after the date of issuance of the Series B Preferred Stock, then the Conversion
Percentage shall decrease by two percent (2%) for each month (that is, each
thirty (30) day period beginning on the 30th day after the Due Date) or partial
month in which the said registration statement has not been declared, or does
not remain, effective; if such registration

                                      -3-
<PAGE>   32
statement has not been declared and does not remain effective on the date which
is one (1) year after the date of issuance of the Series B Preferred Stock, then
the Conversion Percentage shall be fifty percent (50%);

                           (iii) for purposes hereof, the term "Closing Bid
Price" shall mean for any security as of any date, the last closing bid price
for such security on the OTC: Bulletin Board Market as reported by Bloomberg,
L.P., or, if the OTC: Bulletin Board Market is not the principal trading market
for such security, the last closing bid price of such security on the principal
securities exchange or trading market where such security is listed or traded as
reported by Bloomberg, L.P., or, if no last closing bid or trade price is
reported for such security by Bloomberg, L.P., the closing bid price shall be
determined by reference to the closing bid price as reported on the principal
trading market, and if not so reported shall be determined from the average of
the bid prices of any market makers for such security as reported in the "pink
sheets" published by the National Quotation Bureau, Inc. If the closing bid
price cannot be calculated for such security on such date on any of the
foregoing bases, the closing bid price of such security on such date shall be
the fair market value as mutually agreed by the Company and the holders of
two-thirds of the outstanding shares of Series B Preferred Stock.

                  (c) Forced Conversion. In the event the holders of the Series
B Preferred Stock have not exercised the Conversion Rights set forth herein
within two years after the date of issuance of the Series B Preferred Stock (the
"Final Date"), the Series B Preferred Stock shall automatically be converted as
if the holders had exercised their Conversion Rights on the Final Date. In
addition, in the event the Company closes on a public offering of its shares of
Common Stock at a price per share equal to or greater than two times the Maximum
Price, then at the election of the Company given by written notice, each share
of Series B Preferred Stock shall automatically be converted into shares of
Common Stock on the date ("Offering Conversion Date") which is seven business
days prior to the scheduled closing date of such public offering at the
applicable Conversion Rate above and the Offering Conversion Date shall be
deemed the Conversion Date with respect to such shares.

                  (d) Capital Reorganization or Reclassification. If the Common
Stock issuable upon the conversion of the Series B Preferred Stock shall be
changed into the same or different number of shares of any class or classes of
stock, whether by capital reorganization, reclassification, stock split, stock
dividend, or similar event, then and in each such event, the holder of each
share of Series B Preferred Stock shall have the right thereafter to convert
such share into the kind and amount of shares of stock and other securities and
property receivable upon such capital reorganization, reclassification or other
change which such holder would have received had its shares of Series B
Preferred Stock been converted immediately prior to such capital reorganization,
reclassification or other change.

                  (e) Capital Reorganization, Merger or Sale of Assets. If at
any time or from time to time there shall be a capital reorganization of the
Common Stock (other than a subdivision, combination, reclassification or
exchange of shares provided for in Section 5(d) above), or a merger or
consolidation of the Company with or into another corporation, or the sale of
all or substantially all of the Company's properties, stock and/or assets to any
other person or entity (any of which

                                      -4-
<PAGE>   33
events is herein referred to as a "Reorganization"), then as a part of such
Reorganization, provision shall be made so that the holders of the Series B
Preferred Stock shall thereafter be entitled to receive upon conversion of the
Series B Preferred Stock, the number of shares of stock or other securities or
property of the Company, or of the successor corporation resulting from such
Reorganization, to which such holder would have been entitled if such holder had
converted its shares of Series B Preferred Stock immediately prior to such
Reorganization. In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 5 with respect to the rights of
the holders of the Series B Preferred Stock after the Reorganization, to the end
that the provisions of this Section 5 (including adjustment of the number of
shares issuable upon conversion of the Series B Preferred Stock) shall be
applicable after that event in as nearly equivalent a manner as may be
practicable.

                  (f) Certificate as to Adjustments; Notice by Company. Upon the
occurrence of each adjustment or readjustment of the Conversion Price of the
Series B Preferred Stock, the Company, at its expense, shall promptly compute
such adjustment or readjustment in accordance with the terms hereof and prepare
and furnish to each holder of such Series B Preferred Stock a certificate
executed by the president and chief financial officer (or in the absence of a
person designated as the chief financial officer, by the treasurer) setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment are based. The Company shall, upon written
request at any time of any holder of Series B Preferred Stock, furnish or cause
to be furnished to such holder a certificate setting forth (A) the Conversion
Price at the time in effect, and (B) the number of shares of Common Stock and
the amount, if any, of other property which at the time would be received upon
the conversion of a share of Series B Preferred Stock.

                  (g) Exercise of Conversion Rights. Holders of Series B
Preferred Stock may exercise their right to convert the Series B Preferred Stock
by telecopying an executed and completed notice to the Company and delivering
the original notice in the form annexed hereto as Exhibit A ("Notice of
Conversion") and the certificate representing the Series B Preferred Stock (once
fully converted, unless specifically requested otherwise by the Company) by
express courier. Each business date on which a Notice of Conversion is
telecopied to and received by the Company in accordance with the provisions
hereof shall be deemed a "Conversion Date." Such holders of Series B Preferred
Stock which have sent a Notice of Conversion to the Company shall, if requested
by the Company, deliver the originally executed Series B Preferred Stock
certificates to the Company within three business days from the Conversion Date.
The Company will transmit, or instruct its transfer agent to transmit, the
certificates representing shares of Common Stock issuable upon conversion of any
share of Series B Preferred Stock (together with the certificates representing
the Series B Preferred Stock not so converted, if the prior certificate was
delivered to the Company) to the holder thereof via express courier, by
electronic transfer or otherwise, within three business days after the Company
has received the facsimile Notice of Conversion. In addition to any other
remedies which may be available to the holders of shares of Series B Preferred
Stock, except as otherwise stated in the Purchase Agreement, in the event that
the Company fails to deliver, or has failed to contact its transfer agent within
two business days to deliver, such shares of Common Stock within such three
business day period, the holder will be entitled to revoke the relevant Notice
of

                                      -5-
<PAGE>   34
Conversion by delivering a notice to such effect to the Company whereupon the
Company and the holder shall each be restored to their respective positions
immediately prior to delivery of such Notice of Conversion. The Notice of
Conversion and Series B Preferred Stock certificates representing the portion of
the Series B Preferred Stock converted shall be delivered as follows:

                               Attention: Ms. Barbara Will, President

                  (h) Optional Purchase of Additional Common Stock. On any
Conversion Date relating to a conversion of Series B Preferred Stock by a
holder, the converting holder shall have the option (the "Option") to purchase
one (1) additional share of Common Stock for each share of Common Stock issuable
as a result of such conversion at an exercise price per share equal to the
applicable Conversion Price (such additional shares of Common Stock referred to
herein as "Option Shares"). The holder shall (i) indicate on the Notice of
Conversion in respect of such Conversion Date that it is exercising its Option
with respect to such conversion and shall specify the number of shares of Common
Stock with respect to which the Option is being so exercised, and (ii) shall pay
to the Company in immediately available funds within two (2) business days after
such Conversion Date, the aggregate purchase price for the Option Shares then
being purchased. Without limitation, the provisions of this Section 5 above
shall apply to any exercise by the holder of its Option.

                  (i) Lost or Stolen Certificates. Upon receipt by the Company
of evidence of the loss, theft, destruction or mutilation of any Series B
Preferred Stock certificate(s), and (in the case of loss, theft or destruction)
of indemnity or security reasonably satisfactory to the Company, and upon the
cancellation of the Series B Preferred Stock certificate(s), if mutilated, the
Company shall execute and deliver new certificates for Series B Preferred Stock
of like tenure and date. However, the Company shall not be obligated to reissue
such lost or stolen certificates for shares of Series B Preferred Stock if the
holder contemporaneously requests the Company to convert such Series B Preferred
Stock into Common Stock.

                  (j) Fractional Shares. No fractional shares of Common Stock
shall be issued upon conversion of shares of Series B Preferred Stock. In lieu
of any fractional share to which the holder would be entitled for this
paragraph, the number of shares of Common Stock to be received shall be rounded
to the nearest whole share.

                  (k) Partial Conversion. In the event some but not all of the
shares of Series B Preferred Stock represented by a certificate or certificates
are converted, the Company may require

                                      -6-
<PAGE>   35
the holder to surrender the said certificate(s) to the Company within three (3)
business days after such a conversion; if so, the Company shall execute and
deliver to or to the order of the holder, at the expense of the Company, a new
certificate representing the number of shares of Series B Preferred Stock which
were not converted.

                  (l) Reservation of Common Stock. The Company shall at all
times reserve and keep available out of its authorized but unissued shares of
Common Stock, solely for the purpose of effecting the conversion of the shares
of the Series B Preferred Stock (including also exercise of the Option), such
number of its shares of Common Stock as shall from time to time be sufficient or
as may be available to effect the conversion of all outstanding shares of the
Series B Preferred Stock, including also full exercise of the Option, and if at
any time the number of authorized but unissued shares of Common Stock shall not
be sufficient to effect the conversion of all the then outstanding shares of the
Series B Preferred Stock, including also full exercise of the Option, the
Company shall use its best efforts to take such corporate action as may be
necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purpose.

         6. Redemption.

                  (a) The Company may redeem any or all of the outstanding
shares of the Series B Preferred Stock on any date (the "Redemption Date") set
by the Board of Directors of the Company for such redemption at any time at the
Redemption Price, as that term is defined below, for each share of Series B
Preferred Stock, to be paid in cash on the Redemption Date, provided, that
(except as hereinafter provided) the Company shall not send a Redemption Notice,
as that term is defined below, to any of the holders of Series B Preferred
Stock, unless it has good and clear funds, for payment of the Redemption Price
for the shares of Series B Preferred Stock it intends to redeem, in a bank
account controlled by the Company, and provided further, however, that in the
event the redemption is to be made simultaneously with the closing of a public
offering of the Company, then the Company may send a Redemption Notice even if
it does not have such good and clear funds, but not earlier than on the day
prior to the date the public offering is priced.

                  (b) The Redemption Price shall be an amount equal to 127.5% of
the Purchase Price, plus an amount equal to all accrued but unpaid dividends,
whether or not declared, to but excluding the Redemption Date;

                  (c) The Redemption Price shall be payable in cash. If fewer
than all of the outstanding shares of Series B Preferred Stock are to be
redeemed, the redemption shall be pro rata among the holders of the Series B
Preferred Stock based upon the number of shares held by such holders and subject
to such other provisions as may be determined by the Board of Directors of the
Company.

                  (d) Except as otherwise provided in Section 6(a), not less
than five days prior to the Redemption Date, the Company shall send, by
facsimile transmission and by first class mail, postage prepaid, a notice (the
"Redemption Notice") to each holder of Series B Preferred Stock, which notice
shall contain all instructions and materials necessary to enable such holders to
tender

                                      -7-
<PAGE>   36
Series B Preferred Stock pursuant to the redemption. Such notice shall (i) state
that a redemption is being effected, (ii) specify the Redemption Date, (iii)
state that holders will be required to surrender the certificate or certificates
representing such shares, properly endorsed, in the manner and at the place
specified in the notice prior to the close of business on the business day prior
to the Redemption Date, (iv) state that holders may convert all or any portion
their shares of Series B Preferred Stock into shares of Common Stock, provided
that the Company receives the Notice of Conversion within twenty-four hours from
the time the Redemption Notice was received by such holder and that all other
shares shall be deemed to have been redeemed by the Company on the Redemption
Date at the Redemption Price plus all accrued but unpaid cash dividends whether
or not declared. The Company may not redeem any portion of the Series B
Preferred Stock that has been converted on or prior to the date of the
Redemption Notice. In the event the Company fails to deliver the Redemption
Price plus accrued and unpaid cash dividends on or before (i) one day after the
Redemption Date or (ii) in the event the redemption is made simultaneously with
the closing of a public offering of the Company, six days after the closing date
of such public offering, the Redemption Notice shall be null and void and the
Company will relinquish its redemption rights provided by this section.

                  (e) On the Redemption Date, unless the Company defaults in the
payment for the shares of Series B Preferred Stock tendered pursuant to the
redemption, dividends will cease to accrue with respect to the shares of Series
B Preferred Stock tendered. All rights of holders of such tendered shares will
terminate, except for the right to receive payment therefor, on the Redemption
Date.

                  (f) The Company may, at its option, at any time after the
mailing of the Redemption Notice pursuant to Section 6 (d) above, deposit the
aggregate amount payable upon redemption of the Series B Preferred Stock with a
bank or trust company (the "Depositary") having its principal office in New
York, New York, and having a combined capital and surplus (as shown by its then
most recently published financial statement) of at least $200,000,000,
designated by the Board of Directors of the Company, to be held in trust by the
Depositary for payment to the holders of the shares to be redeemed. Upon such
deposit, the Company shall be released and discharged from any obligation to pay
the Redemption Price of the shares to be redeemed, and the holders of the shares
instead shall have the right to receive from the Depositary only, and not from
the Company, the amount payable upon redemption of the shares on surrender to
the Depositary of the certificates representing the shares. Any money so
deposited with the Depositary that is not claimed after one year from the
Redemption Date shall be repaid to the Company by the Depositary on demand, and
the holder of any of the shares shall thereafter look only to the Company for
any payment to which the holder may be entitled. Any interest which accrues on
money deposited with the Depositary shall belong to the Company and shall be
paid to the Company from time to time by the Depositary.

         7. No Reissuance of Series B Preferred Stock. Any share or shares of
Series B Preferred Stock acquired by the Company by reason of redemption,
purchase, conversion or otherwise shall be canceled, shall return to the status
of authorized but unissued preferred stock of no designated series, and shall
not be reissuable or re-sellable by the Company as Series B Preferred Stock.

                  (a) Amendments to Charter. The Company shall not amend its
certificate of incorporation without the approval by the holders of at least a
majority of the then outstanding shares of Series B Preferred Stock if such
amendment would:

                           (i) change the relative seniority rights of the
holders of Series B Preferred Stock as to the payment of dividends in relation
to the holders of any other capital stock of the Company, or create any other

dividends in relation to the holders of Series B Preferred Stock;

                           (ii) reduce the amount payable to the holders of

                           (iv) cancel or modify the rights of the holders of
the Series B Preferred Stock provided for in this Section 8.

         9. Notices of Record Date. In the event of:

                  (a) any taking by the Company of a record of the holders of
any class of securities for the purpose of determining the holders thereof who
are entitled to receive any dividend or other distribution, or any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, or

                  (b) any capital reorganization of the Company, any
reclassification or recapitalization of the capital stock of the Company, any
merger of the Company, or any transfer of all or substantially all of the assets
of the Company to any other corporation, or any other entity or person, or

                  (c) any voluntary or involuntary dissolution, liquidation or
winding up of the Company, then and in each such event the Company shall mail or
cause to be mailed to each holder of Series B Preferred Stock a notice
specifying (i) the date on which any such record is to be taken for the purpose
of such dividend, distribution or right and a description of such dividend,
distribution or right, (ii) the date on which any such reorganization,
reclassification, recapitalization, transfer, merger, dissolution, liquidation
or winding up is expected to become effective and (iii) the time, if any, that
is to be fixed, as to when the holders of record of Common Stock (or other
securities) shall be entitled to exchange their shares of Common Stock (or other
securities) for securities or other

                                      -9-
<PAGE>   38
property deliverable upon such reorganization, reclassification,
recapitalization, transfer, merger, dissolution, liquidation or winding up. Such
notice shall be mailed at least ten days prior to the date specified in such
notice on which such action is to be taken.

         10. Certificate of Incorporation. The statements contained in the
foregoing, creating and designating the said Series B issue of Preferred Stock
and fixing the number, powers, preferences and relative, optional,
participating, and other special rights and the qualifications, limitations and
restrictions shall, upon the effective date of said series, be deemed to be
included in and be a part of the Certificate of Incorporation of the Company
pursuant to the relevant provisions of the General Corporation Law of the State
of Nevada.

         11. Limitation on Number of Conversion Shares. (a) Notwithstanding any
other provision herein, the Company shall not be obligated to issue any shares
of Common Stock upon conversion of the Series B Preferred Stock if the issuance
of such shares of Common Stock would exceed that number of shares of Common
Stock which the Company may issue upon conversion of the Series B Preferred
Stock (the "Exchange Cap") without breaching the Company's obligations under the
rules and regulations of The Nasdaq Stock Market, Inc., except that such
limitation shall not apply in the event that the Company (a) obtains the
approval of its stockholders as required by applicable rules of The Nasdaq Stock
Market, Inc., for issuances of Common Stock in excess of such amount or (b)
obtains a written opinion from outside counsel to the Company that such approval
is not required, which opinion shall be reasonably satisfactory to the holders
of a majority of the shares of Series B Preferred Stock then outstanding;
provided, however, that notwithstanding anything herein to the contrary, the
Company will issue such number of shares of Common Stock issuable upon
conversion of the Series B Preferred Stock at the then current Conversion Price
up to the Exchange Cap. Until such approval or written opinion is obtained, no
holder of Series B Preferred Stock pursuant to the Securities Purchase Agreement
("Purchase Agreement") shall be issued, upon conversion of Series B Preferred
Stock, shares of Common Stock in an amount greater than the product of (i) the
Exchange Cap amount multiplied by (ii) a fraction, the numerator of which is the
number of shares of Series B Preferred Stock issued to such holder pursuant to
the Purchase Agreement and the denominator of which is the aggregate amount of
all the shares of Series B Preferred Stock issued to all holders pursuant to the
Purchase Agreement (the "Cap Allocation Amount"). In the event that any holder
of Series B Preferred Stock shall convert all of such holder's shares of Series
B Preferred Stock into a number of shares of Common Stock which, in the
aggregate, is less than such holder's Cap Allocation Amount, then the difference
between such holder's Cap Allocation Amount and the number of shares of Common
Stock actually issued to such holder shall be allocated to the respective Cap
Allocation Amounts of the remaining holders of Series B Preferred Stock on a pro
rata basis in proportion to the number of shares of Series Preferred Stock then
held by each such holder. The provisions of this paragraph will apply only in
the event the Company becomes listed for trading on the NASDAQ stock market
(either Small Cap or National Market).

                  (b) Conversion Restrictions. Notwithstanding anything to the
contrary set forth herein or in the Certificate of Designations, in no event
shall any holder of the Series B Preferred Stock be entitled to convert Series B
Preferred Stock (or exercise the Option to receive Option

                                      -10-
<PAGE>   39
Shares) in excess of such portion of the principal of the Series B Preferred
Stock that, upon giving effect to such conversion, would cause the aggregate
number of shares of Common Stock beneficially owned by such converting holder
and its affiliates to exceed 4.99% of the outstanding shares of the Common Stock
following such conversion. For purposes of the foregoing proviso, the aggregate
number of shares of Common Stock beneficially owned by the holder and its
affiliates shall include the number of shares of Common Stock issuable upon
conversion of the Series B Preferred Stock with respect to which the
determination of such proviso is being made. Except as set forth in the
preceding sentence, for purposes of this Section, beneficial ownership shall be
calculated in accordance with Section 13(d) of the Securities Exchange Act of
1934, as amended. The limitations imposed by this Section on conversion of
Series B Preferred Stock shall no longer apply, and the holder of the Series B
Preferred Stock may convert all or any portion of the Series B Preferred Stock,
irrespective of the resulting beneficial ownership of the Company's Common
Stock, should any of the following events occur: (I) The Company shall either:
(i) become insolvent; (ii) admit in writing its inability to pay its debts
generally or as they become due; (iii) make an assignment for the benefit of
creditors or commence proceedings for its dissolution; or (iv) apply for, or
consent to the appointment of, a trustee, liquidator, or receiver for its or for
a substantial part of its property or business; or (II) A trustee, liquidator or
receiver shall be appointed for the Company or for a substantial part of its
property or business without the Company's consent and such appointment is not
discharged within sixty (60) days after such appointment; or (III) Any
governmental agency or any court of competent jurisdiction at the instance of
any governmental agency shall assume custody or control of the whole or any
substantial portion of the properties or assets of the Company and shall not be
dismissed within sixty (60) days thereafter; or (IV) Any money judgment, writ or
Note of attachment, or similar process in excess of Five Hundred Thousand United
States Dollars (US$500,000.00) in the aggregate shall be entered or filed
against the Company or any of its properties or assets and shall remain unpaid,
unvacated, unbonded or unstayed for a period of fifteen (15) days or in any
event later than five (5) days prior to the date of any proposed sale
thereunder; or (V) Bankruptcy, reorganization, insolvency or liquidation
proceedings or other proceedings for relief under any bankruptcy law or any law
for the relief of debtors shall be instituted by or against the Company and, if
instituted against the Company, shall not be dismissed within sixty days after
such institution or the Company shall by any action or answer approve of,
consent to, or acquiesce in any such proceedings or admit the material
allegations of, or default in answering a petition filed in, any such
proceeding.

         12. Ranking.

                  The Series B Preferred Stock shall, with respect to dividend
rights and rights on liquidation, winding up and dissolution, rank senior to any
of the (i) Common Stock and rank senior to or on parity with any preferred stock
issued after the date hereof and any other class or series of stock of the
Company.

                  Securities Act of 1933, as amended (the "Securities Act"), or

NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
"SECURITIES ACT"), OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED
OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND UNDER
APPLICABLE STATE SECURITIES LAWS OR IPVOICE.COM, INC. SHALL HAVE RECEIVED AN
OPINION OF ITS COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES
ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT
REQUIRED.

                               WARRANT TO PURCHASE

                             SHARES OF COMMON STOCK

                                       OF

                                IPVOICE.COM, INC.

                              Expires May 22, 2005

No.: A-001                                             Number of Shares: 125,000
Date of Issuance: May 22, 2000

         FOR VALUE RECEIVED, subject to the provisions hereinafter set forth,
the undersigned, IPVoice.Com, Inc., a Nevada corporation (together with its
successors and assigns, the "Issuer"), hereby certifies that Augustine Fund,
L.P.. or its registered assigns is entitled to subscribe for and purchase,
during the period specified in this Warrant, up to 125,000 shares (subject to
adjustment as hereinafter provided) of the duly authorized, validly issued,
fully paid and non-assessable Common Stock of the Issuer, at an exercise price
per share equal to the Warrant Price then in effect, subject, however, to the
provisions and upon the terms and conditions hereinafter set forth. Capitalized
terms used in this Warrant and not otherwise defined herein shall have the
respective meanings specified in Section 7 hereof.

         1. Term. The right to subscribe for and purchase shares of Warrant
Stock represented hereby shall commence on the date of issuance of this Warrant
and shall expire at 5:00 p.m., mountain standard time, on May 22, 2005 (such
period being the "Term").

         2. Method of Exercise Payment: Issuance of New Warrant: Transfer and
Exchange.

         (a) Time of Exercise. The purchase rights represented by this Warrant
may be exercised in whole or in part at any time and from time to time beginning
on the date which is ninety (90) days after the first day of the Term.

                                      -1-
<PAGE>   43
         (b) Method of Exercise. The Holder hereof may exercise this Warrant, in
whole or in part, by the surrender of this Warrant (with the exercise form
attached hereto duly executed) at the principal office of the Issuer, and by the
payment to the Issuer of an amount of consideration therefor equal to the
Warrant Price in effect on the date of such exercise multiplied by the number of
shares of Warrant Stock with respect to which this Warrant is then being
exercised, payable at such Holder's election (i) by certified or official bank
check or (ii) by surrender to the Issuer for cancellation of a portion of this
Warrant representing that number of unissued shares of Warrant Stock which is
equal to the quotient obtained by dividing (A) the product obtained by
multiplying the Warrant Price by the number of shares of Warrant Stock being
purchased upon such exercise by (B) the difference obtained by subtracting the
Warrant Price from the Per Share Market Value as of the date of such exercise,
or (iii) by a combination of the foregoing methods of payment selected by the
Holder of this Warrant. In any case where the consideration payable upon such
exercise is being paid in whole or in part pursuant to the provisions of clause
(ii) of this subsection (b), such exercise shall be accompanied by written
notice from the Holder of this Warrant specifying the manner of payment thereof
and containing a calculation showing the number of shares of Warrant Stock with
respect to which rights are being surrendered thereunder and the net number of
shares to be issued after giving effect to such surrender.

         (c) Issuance of Stock Certificates. In the event of any exercise of the
rights represented by this Warrant in accordance with and subject to the terms
and conditions hereof, (i) certificates for the shares of Warrant Stock so
purchased shall be dated the date of such exercise and delivered to the Holder
hereof within a reasonable time, not exceeding three Trading Days after such
exercise and receipt by the Issuer of the surrendered Warrant, and the Holder
hereof shall be deemed for all purposes to be the Holder of the shares of
Warrant Stock so purchased as of the date of such exercise, and (ii) unless this
Warrant has expired, a new Warrant representing the number of shares of Warrant
Stock, if any, with respect to which this Warrant shall not then have been
exercised (less any amount thereof which shall have been canceled in payment or
partial payment of the Warrant Price as hereinabove provided) shall also be
issued to the Holder hereof at the Issuer's expense within such time.

         (d) Transferability of Warrant. Subject to Section 2(e) and except for
transfers to competitors of the Company or their affiliates, this Warrant may be
transferred by a Purchaser without the consent of the Company; provided, that
the number of Holders which are not affiliates of the initial Holder shall in no
event exceed three (3) without the Issuer's prior written consent. Subject to
the provisions of subsection (e) of this Section 2, this Warrant may be
transferred pursuant to this subsection (d) on the books of the Issuer by the
Holder hereof in person or by duly authorized attorney, upon surrender of this
Warrant at the principal office of the Issuer, properly endorsed (by the Holder
executing an assignment in the form attached hereto) and upon payment of any
necessary transfer tax or other governmental charge imposed upon such transfer.
This Warrant is exchangeable at the principal office of the Issuer for Warrants
for the purchase of the same aggregate number of shares of Warrant Stock, each
new Warrant to represent the right to purchase such number of shares of Warrant
Stock as the Holder hereof shall designate at the time of such exchange. All
Warrants issued on transfers or exchanges shall be dated the Original Issue Date
and shall be identical with this Warrant except as to the number of shares of
Warrant Stock issuable pursuant hereto.

         (e) Compliance with Securities Laws.

                                      -2-
<PAGE>   44
                  (i) The Holder of this Warrant, by acceptance hereof,
         acknowledges that this Warrant or the shares of Warrant Stock to be
         issued upon exercise hereof are being acquired solely for the Holder's
         own account and not as a nominee for any other party, and for
         investment, and that the Holder will not offer, sell or otherwise
         dispose of this Warrant or any shares of Warrant Stock to be issued
         upon exercise hereof except pursuant to an effective registration
         statement, or an exemption from registration, under the Securities Act
         and any applicable state securities laws.

                  (ii) Except as provided in paragraph (iii) below, this Warrant
         and all certificates representing shares of Warrant Stock issued upon
         exercise hereof shall be stamped or imprinted with a legend in
         substantially the following form:

                           THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE
                  UPON EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE
                  SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
                  ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR
                  OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES
                  ACT AND UNDER APPLICABLE STATE SECURITIES LAWS OR THE ISSUER
                  SHALL HAVE RECEIVED AN OPINION OF ITS COUNSEL THAT
                  REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND
                  UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS
                  NOT REQUIRED.

                  (iii) The restrictions imposed by this subsection (e) upon the
         transfer of this Warrant or the shares of Warrant Stock to be purchased
         upon exercise hereof shall terminate (A) when such securities shall
         have been resold pursuant to being effectively registered under the
         Securities Act, (B) upon the Issuer's receipt of an opinion of counsel,
         in form and substance reasonably satisfactory to the Issuer, addressed
         to the Issuer to the effect that such restrictions are no longer
         required to ensure compliance with the Securities Act and state
         securities laws or (C) upon the Issuer's receipt of other evidence
         reasonably satisfactory to the Issuer that such registration and
         qualification under state securities laws is not required. Whenever
         such restrictions shall cease and terminate as to any such securities,
         the Holder thereof shall be entitled to receive from the Issuer (or its
         transfer agent and registrar), without expense (other than applicable
         transfer taxes, if any), new Warrants (or, in the case of shares of
         Warrant Stock, new stock certificates) of like tenor not bearing the
         applicable legend required by paragraph (ii) above relating to the
         Securities Act and state securities laws.

         (f) Continuing Rights of Holder. The Issuer will, at the time of or at
any time after each exercise of this Warrant, upon the request of the Holder
hereof, acknowledge in writing the extent, if any, of its continuing obligation
to afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such Holder shall fail to make any such request, the
failure shall not affect the continuing obligation of the Issuer to afford such
rights to such Holder.

                                      -3-
<PAGE>   45
         3. Stock Fully Paid: Reservation and Listing of Shares: Covenants.

         (a) Stock Fully Paid. The Issuer represents, warrants, covenants and
agrees that all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise hereunder will, upon issuance, be duly authorized,
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges created by or through Issuer. The Issuer further covenants and agrees
that during the period within which this Warrant may be exercised, the Issuer
will at all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

         (b) Reservation. If any shares of Common Stock required to be reserved
for issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any Governmental Authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

         (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action,
intentionally avoid or seek to avoid the observance or performance of any of the
terms of this Warrant, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such actions as may be
necessary or appropriate to protect the rights of the Holder hereof against
dilution (to the extent specifically provided herein) or impairment. Without
limiting the generality of the foregoing, the Issuer will (i) not permit the par
value, if any, of its Common Stock to exceed the then effective Warrant Price,
(ii) not amend or modify any provision of the Certificate of Incorporation or
by-laws of the Issuer in any manner that would adversely affect in any way the
powers, preferences or relative participating, optional or other special rights
of the Common Stock or which would materially adversely affect the rights of the
Holders of the Warrants, provided, however, that issuing new series of preferred
stock or additional shares of existing series of preferred stock shall not be
deemed a violation hereof, (iii) take all such action as may be reasonably
necessary in order that the Issuer may validly and legally issue fully paid and
nonassessable shares of Common Stock, free and clear of any liens, claims,
encumbrances and restrictions (other than as provided herein) upon the exercise
of this Warrant, and (iv) use its best efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having
jurisdiction thereof as may be reasonably necessary to enable the Issuer to
perform its obligations under this Warrant.

         (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the

                                      -4-
<PAGE>   46
case of any such loss, theft or destruction, upon receipt of indemnity or
security satisfactory to the Issuer or, in the case of any such mutilation, upon
surrender and cancellation of such Warrant, the Issuer will make and deliver, in
lieu of such lost, stolen, destroyed or mutilated Warrant, a new Warrant of like
tenor and representing the right to purchase the same number of shares of Common
Stock.

         (e) Rights and Obligations under the Registration Rights Agreement. The
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the Registration Rights Agreement dated as of even date herewith between the
Issuer and the Holder listed on the signature page thereof (as amended from time
to time, the "Registration Rights Agreement"). The Issuer shall keep or cause to
be kept a copy of the Registration Rights Agreement, and any amendments thereto,
at its chief executive office and shall furnish, without charge, copies thereof
to the Holder upon request.

         4. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

         (a) Recapitalization, Reorganization, Reclassification, Consolidation,
Merger or Sale. (i) In case the Issuer after the Original Issue Date shall do
any of the following (each, a "Triggering Event"): (a) consolidate with or merge
into any other Person and the Issuer shall not be the continuing or surviving
corporation of such consolidation or merger, or (b) permit any other Person to
consolidate with or merge into the Issuer and the Issuer shall be the continuing
or surviving Person but, in connection with such consolidation or merger, any
Capital Stock of the Issuer shall be changed into or exchanged for Securities of
any other Person or cash or any other property, or (c) transfer all or
substantially all of its properties or assets to any other Person, or (d) effect
a capital reorganization or reclassification of its Capital Stock, then, and in
the case of each such Triggering Event, proper provision shall be made so that,
upon the basis and the terms and in the manner provided in this Warrant, the
Holder of this Warrant shall be entitled (x) upon the exercise hereof at any
time after the consummation of such Triggering Event, to the extent this Warrant
is not exercised prior to such Triggering Event, to receive at the Warrant Price
in effect at the time immediately prior to the consummation of such Triggering
Event in lieu of the Common Stock issuable upon such exercise of this Warrant
prior to such Triggering Event, the Securities, cash and property to which such
Holder would have been entitled upon the consummation of such Triggering Event
if such Holder had exercised the rights represented by this Warrant immediately
prior thereto, subject to adjustments (subsequent to such corporate action) as
nearly equivalent as possible to the adjustments provided for in Section 4
hereof or (y) to sell this Warrant (or, at such Holder's election, a portion
hereof) concurrently with the Triggering Event to the Person continuing after or
surviving such Triggering Event, or to the Issuer (if Issuer is the continuing
or surviving Person) at a sales price equal to the amount of cash, property
and/or Securities to which a holder of the number of shares of Common Stock
which would otherwise have been delivered upon the exercise of this Warrant
would have been entitled upon the effective date or closing of any such
Triggering Event (the "Event Consideration"), less the amount or portion of such
Event Consideration having a fair value equal to the aggregate Warrant Price
applicable to this Warrant or the portion hereof so sold.

         (ii) Notwithstanding anything contained in this Warrant to the
contrary, the Issuer will not effect any Triggering Event unless, prior to the
consummation thereof, each Person (other than

                                      -5-
<PAGE>   47
the Issuer) which may be required to deliver any Securities, cash or property
upon the exercise of this Warrant as provided herein shall assume, by written
instrument delivered to, and reasonably satisfactory to, the Holder of this
Warrant, (A) the obligations of the Issuer under this Warrant (and if the Issuer
shall survive the consummation of such Triggering Event, such assumption shall
be in addition to, and shall not release the Issuer from, any continuing
obligations of the Issuer under this Warrant) and (B) the obligation to deliver
to such Holder such Securities, cash or property as, in accordance with the
foregoing provisions of this subsection (a), such Holder shall be entitled to
receive, and such Person shall have similarly delivered to such Holder an
opinion of counsel for such Person, which counsel shall be reasonably
satisfactory to such Holder, stating that this Warrant shall thereafter continue
in full force and effect and the terms hereof (including, without limitation,
all of the provisions of this subsection (a)) shall be applicable to the
Securities, cash or property which such Person may be required to deliver upon
any exercise of this Warrant or the exercise of any rights pursuant hereto.

         (iii) If with respect to any Triggering Event, the Holder of this
Warrant has exercised its right as provided in clause (y) of subparagraph (i) of
this subsection (a) to sell this Warrant or a portion thereof, the Issuer agrees
that as a condition to the consummation of any such Triggering Event the Issuer
shall secure such right of Holder to sell this Warrant to the Person continuing
after or surviving such Triggering Event and the Issuer shall not effect any
such Triggering Event unless upon or prior to the consummation thereof the
amounts of cash, property and/or Securities required under such clause (y) are
delivered to the Holder of this Warrant. The obligation of the Issuer to secure
such right of the Holder to sell this Warrant shall be subject to such Holder's
cooperation with the Issuer, including, without limitation, the giving of
customary representations and warranties to the purchaser in connection with any
such sale. Prior notice of any Triggering Event shall be given to the Holder of
this Warrant in accordance with Section 11 hereof.

         (b) Subdivision or Combination of Shares. If the Issuer, at any time
while this Warrant is outstanding, shall subdivide or combine any shares of
Common Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of Holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the increase in the total number of shares of Common Stock outstanding as a
result of such subdivision, or (ii) in the case of a combination of shares, the
Warrant Price shall be proportionately increased (as at the effective date of
such combination or, if the Issuer shall take a record of Holders of its Common
Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

         (c) Certain Dividends and Distributions. If the Issuer, at any time
while this Warrant is outstanding, shall:

                  (i) Stock Dividends. Pay a dividend in, or make any other
         distribution to its stockholders (without consideration therefor) of,
         shares of Common Stock, the Warrant Price shall be adjusted, as at the
         date the Issuer shall take a record of the Holders of the Issuer's
         Capital Stock for the purpose of receiving such dividend or other
         distribution (or if no such record is taken, as at the date of such
         payment or other distribution), to that price determined by multiplying
         the Warrant Price in effect immediately prior to such record date (or
         if no

                                      -6-
<PAGE>   48
         such record is taken, then immediately prior to such payment or other
         distribution), by a fraction (1) the numerator of which shall be the
         total number of shares of Common Stock outstanding immediately prior to
         such dividend or distribution, and (2) the denominator of which shall
         be the total number of shares of Common Stock outstanding immediately
         after such dividend or distribution (plus in the event that the Issuer
         paid cash for fractional shares, the number of additional shares which
         would have been outstanding had the Issuer issued fractional shares in
         connection with said dividends); or

                  (ii) Other Dividends. Pay a dividend on, or make any
         distribution of its assets upon or with respect to (including, but not
         limited to, a distribution of its property as a dividend in liquidation
         or partial liquidation or by way of return of capital), the Common
         Stock (other than as described in clause (i) of this subsection (c)),
         or in the event that the Company shall offer options or rights to
         subscribe for shares of Common Stock, or issue any Common Stock
         Equivalents, to all of its holders of Common Stock, then on the record
         date for such payment, distribution or offer or, in the absence of a
         record date, on the date of such payment, distribution or offer, the
         Holder shall receive what the Holder would have received had it
         exercised this Warrant in full immediately prior to the record date of
         such payment, distribution or offer or, in the absence of a record
         date, immediately prior to the date of such payment, distribution or
         offer.

         (d) Issuance of Additional Shares of Common Stock. If the Issuer, at
any time while this Warrant is outstanding, shall issue any Additional Shares of
Common Stock (otherwise than as provided in the foregoing subsections (a)
through (c) of this Section 4), at a price per share less than the Warrant Price
then in effect or less than the Per Share Market Value then in effect or without
consideration, then the Warrant Price upon each such issuance shall be adjusted
to that price (rounded to the nearest cent) determined by multiplying the
Warrant Price then in effect by a fraction:

                  (i) the numerator of which shall be equal to the sum of (A)
         the number of shares of Common Stock outstanding immediately prior to
         the issuance of such Additional Shares of Common Stock plus (B) the
         number of shares of Common Stock (rounded to the nearest whole share)
         which the aggregate consideration for the total number of such
         Additional Shares of Common Stock so issued would purchase at a price
         per share equal to the greater of the Per Share Market Value then in
         effect and the Warrant Price then in effect, and

                  (ii) the denominator of which shall be equal to the number of
         shares of Common Stock outstanding immediately after the issuance of
         such Additional Shares of Common Stock.

The provisions of this subsection (d) shall not apply under any of the
circumstances for which an adjustment is provided in subsections (a), (b) or (c)
of this Section 4. No adjustment of the Warrant Price shall be made under this
subsection (d) upon the issuance of any Additional Shares of Common Stock which
are issued pursuant to any Common Stock Equivalent if upon the issuance of such
Common Stock Equivalent (x) any adjustment shall have been made pursuant to
subsection (e) of this Section 4 or (y) no adjustment was required pursuant to
subsection (e) of this Section 4. No adjustment of the Warrant Price shall be
made under this subsection (d) in an amount less than $.01 per share, but any
such lesser adjustment shall be carried forward and shall be made at the time
and

                                      -7-
<PAGE>   49
together with the next subsequent adjustment, if any, which together with any
adjustments so carried forward shall amount to $.01 per share or more, provided
that upon any adjustment of the Warrant Price as a result of any dividend or
distribution payable in Common Stock or Convertible Securities or the
reclassification, subdivision or combination of Common Stock into a greater or
smaller number of shares, the foregoing figure of $.01 per share (or such figure
as last adjusted) shall be adjusted (to the nearest one-half cent) in proportion
to the adjustment in the Warrant Price.

         (e) Issuance of Common Stock Equivalents. If the Issuer, at any time
while this Warrant is outstanding, shall issue any Common Stock Equivalent
(except Common Stock Equivalents currently outstanding or issued pursuant to
contractual arrangements in existence as of the date of this Warrant) and the
price per share for which Additional Shares of Common Stock may be issuable
thereafter pursuant to such Common Stock Equivalent shall be less than the
Warrant Price then in effect or less than the Per Share Market Value then in
effect, or if, after any such issuance of Common Stock Equivalents, the price
per share for which Additional Shares of Common Stock may be issuable thereafter
is amended or adjusted, and such price as so amended shall be less than the
Warrant Price or less than the Per Share Market Value in effect at the time of
such amendment, then the Warrant Price upon each such issuance or amendment
shall be adjusted as provided in the first sentence of subsection (d) of this
Section 4 on the basis that (1) the maximum number of Additional Shares of
Common Stock issuable pursuant to all such Common Stock Equivalents shall be
deemed to have been issued (whether or not such Common Stock Equivalents are
actually then exercisable, convertible or exchangeable in whole or in part) as
of the earlier of (A) the date on which the Issuer shall enter into a firm
contract for the issuance of such Common Stock Equivalent, or (B) the date of
actual issuance of such Common Stock Equivalent, and (2) the aggregate
consideration for such maximum number of Additional Shares of Common Stock shall
be deemed to be the minimum consideration received or receivable by the Issuer
for the issuance of such Additional Shares of Common Stock pursuant to such
Common Stock Equivalent. No adjustment of the Warrant Price shall be made under
this subsection (e) upon the issuance of any Convertible Security which is
issued pursuant to the exercise of any warrants or other subscription or
purchase rights therefor, if any adjustment shall previously have been made in
the Warrant Price then in effect upon the issuance of such warrants or other
rights pursuant to this subsection (e). If no adjustment is required under this
subsection (e) upon issuance of any Common Stock Equivalent or once an
adjustment is made under this subsection (e) based upon the Per Share Market
Value in effect on the date of such adjustment, no further adjustment shall be
made under this subsection (e) based solely upon a change in the Per Share
Market Value after such date.

         (f) Purchase of Common Stock by the Issuer. If the Issuer at any time
while this Warrant is outstanding shall, directly or indirectly through a
Subsidiary or otherwise, purchase, redeem or otherwise acquire any shares of
Common Stock at a price per share greater than the Per Share Market Value then
in effect, then the Warrant Price upon each such purchase, redemption or
acquisition shall be adjusted to that price determined by multiplying such
Warrant Price by a fraction (i) the numerator of which shall be the number of
shares of Common Stock outstanding immediately prior to such purchase,
redemption or acquisition minus the number of shares of Common Stock which the
aggregate consideration for the total number of such shares of Common Stock so
purchased, redeemed or acquired would purchase at the Per Share Market Value;
and (ii) the denominator of which shall be the number of shares of Common Stock
outstanding immediately after such purchase, redemption or acquisition. For the
purposes of this subsection (f), the date as of which the Per Share Market Value
shall be computed shall be the earlier of (x) the date on which

                                      -8-
<PAGE>   50
the Issuer shall enter into a firm contract for the purchase, redemption or
acquisition of such Common Stock, or (y) the date of actual purchase, redemption
or acquisition of such Common Stock. For the purposes of this subsection (f), a
purchase, redemption or acquisition of a Common Stock Equivalent shall be deemed
to be a purchase of the underlying Common Stock, and the computation herein
required shall be made on the basis of the full exercise, conversion or exchange
of such Common Stock Equivalent on the date as of which such computation is
required hereby to be made, whether or not such Common Stock Equivalent is
actually exercisable, convertible or exchangeable on such date. Notwithstanding
anything in this Section to the contrary, no adjustment shall be made in the
event the Issuer redeems or attempts to redeem Series A Preferred Shares (as
defined in the Purchase Agreement) and the warrants accompanying the Series A
Preferred Shares.

         (g) Other Provisions Applicable to Adjustments Under this Section 4.
The following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4:

                  (i) Computation of Consideration. The consideration received
         by the Issuer shall be deemed to be the following: to the extent that
         any Additional Shares of Common Stock or any Common Stock Equivalents
         shall be issued for a cash consideration, the consideration received by
         the Issuer therefor, or if such Additional Shares of Common Stock or
         Common Stock Equivalents are offered by the Issuer for subscription,
         the subscription price, or, if such Additional Shares of Common Stock
         or Common Stock Equivalents are sold to underwriters or dealers for
         public offering without a subscription offering, the public offering
         price, in any such case excluding any amounts paid or receivable for
         accrued interest or accrued dividends and without deduction of any
         compensation, discounts, commissions, or expenses paid or incurred by
         the Issuer for or in connection with the underwriting thereof or
         otherwise in connection with the issue thereof; to the extent that such
         issuance shall be for a consideration other than cash, then, except as
         herein otherwise expressly provided, the fair market value of such
         consideration at the, time of such issuance as determined in good faith
         by the Board. The consideration for any Additional Shares of Common
         Stock issuable pursuant to any Common Stock Equivalents shall be the
         consideration received by the Issuer for issuing such Common Stock
         Equivalents, plus the additional consideration payable to the Issuer
         upon the exercise, conversion or exchange of such Common Stock
         Equivalents. In case of the issuance at any time of any Additional
         Shares of Common Stock or Common Stock Equivalents in payment or
         satisfaction of any dividend upon any class of Capital Stock of the
         Issuer other than Common Stock, the Issuer shall be deemed to have
         received for such Additional Shares of Common Stock or Common Stock
         Equivalents a consideration equal to the amount of such dividend so
         paid or satisfied. In any case in which the consideration to be
         received or paid shall be other than cash, the Board shall notify the
         Holder of this Warrant of its determination of the fair market value of
         such consideration prior to payment or accepting receipt thereof. If,
         within thirty days after receipt of said notice, the Majority Holders
         shall notify the Board in writing of their objection to such
         determination, a determination of the fair market value of such
         consideration shall be made by an Independent Appraiser selected by the
         Majority Holders with the approval of the Board (which approval shall
         not be unreasonably withheld), whose fees and expenses shall be paid by
         the Issuer.

                  (ii) Readjustment of Warrant Price. Upon the expiration or
         termination of the right to convert, exchange or exercise any Common
         Stock Equivalent the issuance of which

                                      -9-
<PAGE>   51
         effected an adjustment in the Warrant Price, if such Common Stock
         Equivalent shall not have been converted, exercised or exchanged in its
         entirety, the number of shares of Common Stock deemed to be issued and
         outstanding by reason of the fact that they were issuable upon
         conversion, exchange or exercise of any such Common Stock Equivalent
         shall no longer be computed as set forth above, and the Warrant Price
         shall forthwith be readjusted and thereafter be the price which it
         would have been (but reflecting any other adjustments in the Warrant
         Price made pursuant to the provisions of this Section 4 after the
         issuance of such Common Stock Equivalent) had the adjustment of the
         Warrant Price been made in accordance with the issuance or sale of the
         number of Additional Shares of Common Stock actually issued upon
         conversion, exchange or issuance of such Common Stock Equivalent and
         thereupon only the number of Additional Shares of Common Stock actually
         so issued shall be deemed to have been issued and only the
         consideration actually received by the Issuer (computed as in clause
         (i) of this subsection (g)) shall be deemed to have been received by
         the Issuer.

                  (iii) Outstanding Common Stock. The number of shares of Common
         Stock at any time outstanding shall (A) not include any shares thereof
         then directly or indirectly owned or held by or for the account of the
         Issuer or any of its Subsidiaries, and (B) be deemed to include all
         shares of Common Stock then issuable upon conversion, exercise or
         exchange of any then outstanding Common Stock Equivalents or any other
         evidences of Indebtedness, shares of Capital Stock (including, without
         limitation, the Preferred Stock) or other Securities which are or may
         be at any time convertible into or exchangeable for shares of Common
         Stock or Other Common Stock.

         (h) Other Action Affecting Common Stock. In case after the Original
Issue Date the Issuer shall take any action affecting its Common Stock, other
than an action described in any of the foregoing subsections (a) through (g) of
this Section 4, inclusive, and the failure to make any adjustment would not
fairly protect the purchase rights represented by this Warrant in accordance
with the essential intent and principle of this Section 4, then the Warrant
Price shall be adjusted in such manner and at such time as the Board may in good
faith determine to be equitable in the circumstances.

         (i) Adjustment of Warrant Share Number. Upon each adjustment in the
Warrant Price pursuant to any of the foregoing provisions of this Section 4, the
Warrant Share Number shall be adjusted, to the nearest whole share, to the
product obtained by multiplying the Warrant Share Number immediately prior to
such adjustment in the Warrant Price by a fraction, the numerator of which shall
be the Warrant Price immediately before giving effect to such adjustment and the
denominator of which shall be the Warrant Price immediately after giving effect
to such adjustment. If the Issuer shall be in default under any provision
contained in Section 3 of this Warrant so that shares issued at the Warrant
Price adjusted in accordance with this Section 4 would not be validly issued,
the adjustment of the Warrant Share Number provided for in the foregoing
sentence shall nonetheless be made and the Holder of this Warrant shall be
entitled to purchase such greater number of shares at the lowest price at which
such shares may then be validly issued under applicable law. Such exercise shall
not constitute a waiver of any claim arising against the Issuer by reason of its
default under Section 3 of this Warrant.

                                      -10-
<PAGE>   52
         (j) Form of Warrant after Adjustments. The form of this Warrant need
not be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

         5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to one of the national
accounting firms currently known as the "big five" selected by the Holder,
provided that the Issuer shall have ten days after receipt of notice from such
Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty days after submission to it
of such dispute. Such opinion shall be final and binding on the parties hereto.
The fees and expenses of such accounting firm shall be paid by the Issuer.

         6. Fractional Shares. No fractional shares of Warrant Stock will be
issued in connection with and exercise hereof; rather the number of shares of
Warrant Stock shall be rounded up or down to the nearest whole share.

deemed modified to the extent necessary to make it enforceable by such court or
agency. If any such provision is not enforceable as set forth in the preceding
sentence, the unenforceability of such provision shall not affect the other
provisions of this Warrant, but this Warrant shall be construed as if such
unenforceable provision had never been contained herein.

         2.       Registration.

                  (a) Required Registration. On or prior to the Filing Date, the
Company shall prepare and file with the Commission a Registration Statement
covering all Registrable Securities for an offering to be made on a continuous
basis pursuant to Rule 415. The Registration Statement shall be on Form SB-1,
Form SB-2 or Form S-3 (except if the Company is not then eligible to register
for resale the Registrable Securities on Form SB-1, Form SB-2 or Form S-3, in
which case such registration shall be on another appropriate form in accordance

                                       3
<PAGE>   63
herewith). The Company shall use its reasonable best efforts to cause the
Registration Statement to be declared effective under the Securities Act as
promptly as possible after the filing thereof, but in any event prior to the
Effectiveness Date, and to keep such Registration Statement continuously
effective under the Securities Act until such date as is the earlier of (x) the
date when all Registrable Securities covered by such Registration Statement have
been sold by the Purchaser or (y) the date on which the Registrable Securities
may be sold without any restriction pursuant to Rule 144(k) as determined by the
counsel to the Company pursuant to a written opinion letter, addressed to the
Company's transfer agent to such effect (the "Effectiveness Period"). If an
additional Registration Statement is required to be filed because a majority of
the holders of Preferred Stock reasonably determine that the actual number of
shares of Common Stock into which the Preferred Stock is convertible and the
Warrants and Option are exercisable may exceed the number of shares of Common
Stock initially registered in respect of the Conversion Shares, the Option
Shares, the Dividend Shares and the Warrant Shares based upon the computation on
the Closing Date, the holders shall give the Company written notice of such
fact, and the Company shall have twenty (20) Business Days from the date of its
receipt of such notice to file such additional Registration Statement. The
Company shall use its best efforts to cause such additional Registration
Statement to be declared effective by the Commission as soon as possible, but in
no event later than ninety (90) days after filing.

                  (b) Shelf Registration. If the Company is not on the Filing
Date eligible to file a registration statement on Form S-3, then as soon as
possible but no later than thirty (30) days after becoming eligible to file a
registration statement for a secondary or resale offering of the Registrable
Securities on Form S-3, the Company shall prepare and file with the Commission a
post-effective amendment to Form SB-1 or Form SB-2 (or such other applicable
form filed in accordance with Section 2(a) above) on Form S-3 to continue the
registration of all Registrable Securities pursuant to a "shelf" Registration
Statement on Form S-3 covering all Registrable Securities for an offering to be
made on a continuous basis pursuant to Rule 415. Notwithstanding anything to the
contrary contained herein, at no time during the Effectiveness Period shall any
of the Registrable Securities cease being registered.

         3.       Registration Procedures.

                  In connection with the Company's registration obligations
hereunder, the Company shall:

                  (a) Prepare and file with the Commission on or prior to the
Filing Date, a Registration Statement on Form SB-1 or Form SB-2 (or if the
Company is not then eligible to register for resale the Registrable Securities
on Form SB-1 or Form SB-2 such registration shall be on another appropriate form
in accordance herewith) in accordance with the method or methods of distribution
thereof as specified by the Holder (except if otherwise directed by the Holder),
and cause the Registration Statement to become effective and remain effective as
provided herein; provided, however, that not less than five (5) Business Days
prior to the filing of the Registration Statement or any related Prospectus or
any amendment or supplement thereto (including any document that would be
incorporated therein by reference), the Company shall (i) furnish to the Holder
and any Special Counsel, copies of all such documents proposed to be filed,
which documents (other than those incorporated by reference) will be subject to
the review of the Holder and such Special Counsel, and (ii) at the request of
the Holder cause its officers and

                                       4
<PAGE>   64
directors, counsel and independent certified public accountants to respond to
such inquiries as shall be necessary, in the reasonable opinion of counsel to
such Holder, to conduct a reasonable investigation within the meaning of the
Securities Act. The Company shall not file the Registration Statement or any
such Prospectus or any amendments or supplements thereto to which the Holder or
any Special Counsel shall reasonably object in writing within three (3) Business
Days of their receipt thereof.

                  (b) (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement as may be
necessary to keep the Registration Statement continuously effective as to the
applicable Registrable Securities for the Effectiveness Period and prepare and
file with the Commission such additional Registration Statements in order to
register for resale under the Securities Act all of the Registrable Securities;
(ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424 (or any similar provisions then in force) promulgated under the
Securities Act; (iii) respond as promptly as possible to any comments received
from the Commission with respect to the Registration Statement or any amendment
thereto and as promptly as possible provide the Holder true and complete copies
of all correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
applicable period in accordance with the intended methods of disposition by the
Holder thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

                  (c) Notify the Holder of Registrable Securities to be sold and
any Special Counsel as promptly as possible (and, in the case of (i)(A) below,
not less than five (5) Business Days prior to such filing) and (if requested by
any such Person) confirm such notice in writing no later than one (1) Business
Day following the day (i)(A) when a Prospectus or any Prospectus supplement or
post-effective amendment to the Registration Statement is proposed to be filed;
(B) when the Commission notifies the Company whether there will be a "review" of
such Registration Statement and whenever the Commission comments in writing on
such Registration Statement and (C) with respect to the Registration Statement
or any post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable Securities or the initiation of any Proceedings for that
purpose; (iv) if at any time any of the representations and warranties of the
Company contained in any agreement contemplated hereby ceases to be true and
correct in all material respects; (v) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (vi) of the occurrence of any event that makes any statement made
in the Registration Statement or Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated

                                       5
<PAGE>   65
therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

                  (d) Use its best efforts to avoid the issuance of, or, if
issued, obtain the withdrawal of, (i) any order suspending the effectiveness of
the Registration Statement or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

                  (e) If requested by the Holders of a majority in interest of
the Registrable Securities, (i) promptly incorporate in a Prospectus supplement
or post-effective amendment to the Registration Statement such information as
the Company reasonably agrees should be included therein and (ii) make all
required filings of such Prospectus supplement or such post-effective amendment
as soon as reasonably practicable after the Company has received notification of
the matters to be incorporated in such Prospectus supplement or post-effective
amendment.

                  (f) Furnish to the Holder and any Special Counsel, without
charge, at least one conformed copy of each Registration Statement and each
amendment thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the
Commission.

                  (g) Promptly deliver to the Holder and any Special Counsel,
without charge, as many copies of the Prospectus or Prospectuses (including each
form of prospectus) and each amendment or supplement thereto as such Persons may
reasonably request; and the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders in connection with the offering and sale of the Registrable Securities
covered by such Prospectus and any amendment or supplement thereto.

                  (h) Prior to any public offering of Registrable Securities,
use its best efforts to register or qualify or cooperate with the selling
Holders and any Special Counsel in connection with the registration or
qualification (or exemption from such registration or qualification) of such
Registrable Securities for offer and sale under the securities or Blue Sky laws
of such jurisdictions within the United States as any Holder reasonably requests
in writing, to keep each such registration or qualification (or exemption
therefrom) effective during the Effectiveness Period and to do any and all other
acts or things reasonably necessary or advisable to enable the disposition in
such jurisdictions of the Registrable Securities covered by a Registration
Statement; provided, however, that the Company shall not be required to qualify
generally to do business in any jurisdiction where it is not then so qualified
or to take any action that would subject it to general service of process in any
such jurisdiction where it is not then so subject or subject the Company to any
material tax in any such jurisdiction where it is not then so subject.

                  (i) Cooperate with the Holder to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold pursuant to a Registration Statement, which certificates shall be free
of all restrictive legends, and to enable such Registrable

                                       6
<PAGE>   66
Securities to be in such denominations and registered in such names as any
Holder may request within at least two (2) Business Days after notice thereof.

                  (j) Upon the occurrence of any event contemplated by Section
3(c)(vi), as promptly as possible, prepare a supplement or amendment, including
a post-effective amendment, to the Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, and file any other required document so that, as
thereafter delivered, neither the Registration Statement nor such Prospectus
will contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.

                  (k) Use its best efforts to cause all Registrable Securities
relating to such Registration Statement to be listed on the OTC Bulletin Board
and any other securities exchange, quotation system, market or over-the-counter
bulletin board, if any, on which similar securities issued by the Company are
then listed as and when required pursuant to the Purchase Agreement.

                  (l) Comply in all material respects with all applicable rules
and regulations of the Commission and make generally available to its security
holders earning statements satisfying the provisions of Section 11(a) of the
Securities Act and Rule 158 not later than 45 days after the end of any 12-month
period (or 90 days after the end of any 12-month period if such period is a
fiscal year) commencing on the first day of the first fiscal quarter of the
Company after the effective date of the Registration Statement, which statement
shall conform to the requirements of Rule 158.

                  (m) Require each selling Holder to furnish to the Company
information regarding such Holder and the distribution of such Registrable
Securities as is required by law to be disclosed in the Registration Statement,
and the Company may exclude from such registration the Registrable Securities of
any such Holder who fails to furnish such information within a reasonable time
prior to the filing of each Registration Statement, supplemented Prospectus
and/or amended Registration Statement.

                  If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any similar federal statute then in
force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

                  Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(g) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective as contemplated by
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to them in connection with sales of Registrable Securities pursuant
to the Registration Statement.

                                       7
<PAGE>   67
                  Each Holder agrees by its acquisition of such Registrable
Securities that, upon receipt of a notice from the Company of the occurrence of
any event of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv),
3(c)(v) or 3(c)(vi), such Holder will forthwith discontinue disposition of such
Registrable Securities under the Registration Statement until such Holder's
receipt of the copies of the supplemented Prospectus and/or amended Registration
Statement contemplated by Section 3(j), or until it is advised in writing (the
"Advice") by the Company that the use of the applicable Prospectus may be
resumed, and, in either case, has received copies of any additional or
supplemental filings that are incorporated or deemed to be incorporated by
reference in such Prospectus or Registration Statement.

                  (n) If (i) there is material non-public information regarding
the Company which the Company's Board of Directors (the "Board") reasonably
determines not to be in the Company's best interest to disclose and which the
Company is not otherwise required to disclose, or (ii) there is a significant
business opportunity (including, but not limited to, the acquisition or
disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board reasonably determines not to be in the Company's
best interest to disclose and which the Company would be required to disclose
under the Registration Statement, then the Company may postpone or suspend
filing or effectiveness of a registration statement for a period not to exceed
20 consecutive days, provided that the Company may not postpone or suspend its
obligation under this Section 3(n) for more than 45 days in the aggregate during
any 12 month period (each, a "Blackout Period"); provided, however, that no such
postponement or suspension shall be permitted for consecutive 20 day periods,
arising out of the same set of facts, circumstances or transactions.

         4.       Registration Expenses

                  All fees and expenses incident to the performance of or
compliance with this Agreement by the Company shall be borne by the Company
whether or not the Registration Statement is filed or becomes effective and
whether or not any Registrable Securities are sold pursuant to the Registration
Statement. The fees and expenses referred to in the foregoing sentence shall
include, without limitation, (i) all registration and filing fees (including,
without limitation, fees and expenses (A) with respect to filings required to be
made with the OTC Bulletin Board and each other securities exchange or market on
which Registrable Securities are required hereunder to be listed, (B) with
respect to filings required to be made with the Commission, (C) with respect to
filings required to be made under the OTC Bulletin Board and (D) in compliance
with state securities or Blue Sky laws (including, without limitation, fees and
disbursements of counsel for the Holder in connection with Blue Sky
qualifications of the Registrable Securities and determination of the
eligibility of the Registrable Securities for investment under the laws of such
jurisdictions as the Holders of a majority of Registrable Securities may
designate)), (ii) printing expenses (including, without limitation, expenses of
printing certificates for Registrable Securities and of printing prospectuses if
the printing of prospectuses is requested by the holders of a majority of the
Registrable Securities included in the Registration Statement), (iii) messenger,
telephone and delivery expenses incurred by the Company, (iv) fees and
disbursements of counsel for the Company and Special Counsel for the Holder, in
the case of the Special Counsel, to a maximum amount of $2,500.00 during the
term of this Agreement, (v) Securities Act liability insurance, if the Company
so desires such

                                       8
<PAGE>   68
insurance, and (vi) fees and expenses of all other Persons retained by the
Company in connection with the consummation of the transactions contemplated by
this Agreement, including, without limitation, the Company's independent public
accountants (including the expenses of any comfort letters or costs associated
with the delivery by independent public accountants of a comfort letter or
comfort letters). In addition, the Company shall be responsible for all of its
internal expenses incurred in connection with the consummation of the
transactions contemplated by this Agreement (including, without limitation, all
salaries and expenses of its officers and employees performing legal or
accounting duties), the expense of any annual audit, the fees and expenses
incurred in connection with the listing of the Registrable Securities on any
securities exchange as required hereunder.

         5.       Indemnification

                  (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents, brokers (including brokers who
offer and sell Registrable Securities as principal as a result of a pledge or
any failure to perform under a margin call of Common Stock), investment advisors
and employees of each of them, each Person who controls any such Holder (within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) and the officers, directors, agents and employees of each such controlling
Person, to the fullest extent permitted by applicable law, from and against any
and all losses, claims, damages, liabilities, costs (including, without
limitation, costs of preparation and attorneys' fees) and expenses
(collectively, "Losses"), as incurred, arising out of or relating to any untrue
or alleged untrue statement of a material fact contained in the Registration
Statement, any Prospectus or any form of prospectus or in any amendment or
supplement thereto or in any preliminary prospectus, or arising out of or
relating to any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein (in the case of any
Prospectus or form of prospectus or supplement thereto, in the light of the
circumstances under which they were made) not misleading, except to the extent,
but only to the extent, that such untrue statements or omissions are based
solely or in material part upon information regarding such Holder furnished to
the Company by such Holder, which information was reasonably relied on by the
Company for use therein or to the extent that such information relates to such
Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of
prospectus or in any amendment or supplement thereto. The Company shall notify
the Holder promptly of the institution, threat or assertion of any Proceeding of
which the Company is aware in connection with the transactions contemplated by
this Agreement. Such indemnity shall remain in full force and effect regardless
of any investigation made by or on behalf of an Indemnified Party and shall
survive the transfer of the Registrable Securities by the Holder.

                  (b) Indemnification by Holder. The Holders shall, severally
and not jointly, indemnify and hold harmless the Company, the directors,
officers, agents and employees, each Person who controls the Company (within the
meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act),
and the directors, officers, agents or employees of such controlling Persons, to
the fullest extent permitted by applicable law, from and against all Losses, as
incurred, arising solely or in material part out of or based solely or in
 material part

                                       9
<PAGE>   69
upon any untrue statement of a material fact contained in the Registration
Statement, any Prospectus, or any form of prospectus, or arising solely or in
material part out of or based solely or in material part upon any omission of a
material fact required to be stated therein or necessary to make the statements
therein (in the case of any Prospectus or form of prospectus or supplement
thereto, in the light of the circumstances under which they were made) not
misleading, to the extent, but only to the extent, that such untrue statement or
omission is contained in or omitted from any information so furnished by such
Holder to the Company and that such information was reasonably relied upon by
the Company for use in the Registration Statement, such Prospectus or such form
of prospectus or to the extent that such information relates to such Holder or
such Holder's proposed method of distribution of Registrable Securities and was
reviewed and expressly approved in writing by such Holder expressly for use in
the Registration Statement, such Prospectus or such form of prospectus.
Notwithstanding anything to the contrary contained herein, the Holder shall be
liable under this Section 5(b) for only that amount as does not exceed the net
proceeds to such Holder as a result of the sale of Registrable Securities
pursuant to such Registration Statement.

                  (c) Conduct of Indemnification Proceedings. If any Proceeding
shall be brought or asserted against any Person entitled to indemnity hereunder
(an "Indemnified Party"), such Indemnified Party promptly shall notify the
Person from whom indemnity is sought (the "Indemnifying Party) in writing, and
the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all fees and expenses incurred in connection with defense thereof;
provided, that the failure of any Indemnified Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant to
this Agreement, except (and only) to the extent that it shall be finally
determined by a court of competent jurisdiction (which determination is not
subject to appeal or further review) that such failure shall have proximately
and materially adversely prejudiced the Indemnifying Party.

                  An Indemnified Party shall have the right to employ separate
counsel in any such Proceeding and to participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such
Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in
writing to pay such fees and expenses; or (2) the Indemnifying Party shall have
failed promptly to assume the defense of such Proceeding and to employ counsel
reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3)
the named parties to any such Proceeding (including any impleaded parties)
include both such Indemnified Party and the Indemnifying Party, and such
Indemnified Party shall have been advised by counsel that a conflict of interest
is likely to exist if the same counsel were to represent such Indemnified Party
and the Indemnifying Party (in which case, if such Indemnified Party notifies
the Indemnifying Party in writing that it elects to employ separate counsel at
the expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an

                                       10
<PAGE>   70
unconditional release of such Indemnified Party from all liability on claims
that are the subject matter of such Proceeding.

                  All fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such Proceeding in a manner not
inconsistent with this Section) shall be paid to the Indemnified Party, as
incurred, within ten (10) Business Days of written notice thereof to the
Indemnifying Party (regardless of whether it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder; provided, that
the Indemnifying Party may require such Indemnified Party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially
determined that such Indemnified Party is not entitled to indemnification
hereunder).

                  (d) Contribution. If a claim for indemnification under Section
5(a) or 5(b) is unavailable to an Indemnified Party because of a failure or
refusal of a governmental authority to enforce such indemnification in
accordance with its terms (by reason of public policy or otherwise), then each
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such Losses, in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party and Indemnified Party in connection with the
actions, statements or omissions that resulted in such Losses as well as any
other relevant equitable considerations. The relative fault of such Indemnifying
Party and Indemnified Party shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission of a material fact,
has been taken or made by, or relates to information supplied by, such
Indemnifying, Party or Indemnified Party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
action, statement or omission. The amount paid or payable by a party as a result
of any Losses shall be deemed to include, subject to the limitations set forth
in Section 5(c), any reasonable attorneys' or other reasonable fees or expenses
incurred by such party in connection with any Proceeding to the extent such
party would have been indemnified for such fees or expenses if the
indemnification provided for in Sections 5(a) and 5(b) was available to such
party in accordance with its terms. Notwithstanding anything to the contrary
contained herein, the Holder shall be liable or required to contribute under
this Section 5(d) for only that amount as does not exceed the net proceeds to
such Holder as a result of the sale of Registrable Securities pursuant to such
Registration Statement.

                  The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 5(d) were determined by pro
rata allocation or by any other method of allocation that does not take into
account the equitable considerations referred to in the immediately preceding
paragraph. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

                  The indemnity and contribution agreements contained in this
Section are in addition to any liability that the Indemnifying Parties may have
to the Indemnified Parties.

         6. Rule 144.

                                       11
<PAGE>   71
                  As long as any Holder owns Preferred Stock, Dividend Shares,
Conversion Shares, Option Shares, Warrants or Warrant Shares, the Company
covenants to timely file (or obtain extensions in respect thereof and file
within the applicable grace period) all reports required to be filed by the
Company after the date hereof pursuant to Section 13(a) or 15(d) of the Exchange
Act and to promptly furnish the Holder with true and complete copies of all such
filings. As long as any Holder owns Preferred Stock, Dividend Shares, Conversion
Shares, Option Shares, Warrants or Warrant Shares, if the Company is not
required to file reports pursuant to Section 13(a) or 15(d) of the Exchange Act,
it will prepare and furnish to the Holder and make publicly available in
accordance with Rule 144(c) promulgated under the Securities Act annual and
quarterly financial statements, together with a discussion and analysis of such
financial statements in form and substance substantially similar to those that
would otherwise be required to be included in reports required by Section 13(a)
or 15(d) of the Exchange Act, as well as any other information required thereby,
in the time period that such filings would have been required to have been made
under the Exchange Act. The Company further covenants that it will take such
further action as any Holder may reasonably request, all to the extent required
from time to time to enable such Person to sell Dividend Shares, Conversion
Shares, Option Shares and Warrant Shares without registration under the
Securities Act within the limitation of the exemptions provided by Rule 144
promulgated under the Securities Act, including providing any legal opinions of
counsel to the Company referred to in the Purchase Agreement. Upon the request
of any Holder, the Company shall deliver to such Holder a written certification
of a duly authorized officer as to whether it has complied with such
requirements.

         7.       Miscellaneous.

                  (a) Remedies. In the event of a breach by the Company or by a
Holder, of any of their obligations under this Agreement, each Holder or the
Company, as the case may be, in addition to being entitled to exercise all
rights granted by law and under this Agreement, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Company and each Holder agree that monetary damages would not provide adequate
compensation for any losses incurred by reason of a breach by it of any of the
provisions of this Agreement and hereby further agrees that, in the event of any
action for specific performance in respect of such breach, it shall waive the
defense that a remedy at law would be adequate.

                  (b) No Inconsistent Agreements. Neither the Company nor any of
its subsidiaries has, as of the date hereof entered into and currently in
effect, nor shall the Company or any of its subsidiaries, on or after the date
of this Agreement, enter into any agreement with respect to its securities that
is inconsistent with the rights granted to the Holder in this Agreement or
otherwise conflicts with the provisions hereof except for registration rights
provisions disclosed in the Company's Schedule to the Purchase Agreement. Except
for registration rights provisions disclosed in the Company's Schedule to the
Purchase Agreement, neither the Company nor any of its subsidiaries has
previously entered into any agreement currently in effect granting any
registration rights with respect to any of its securities to any Person. Without
limiting the generality of the foregoing, without the written consent of the
Holders of a majority of the then outstanding Registrable Securities, the
Company shall not grant to any Person the right to request the Company to
register any securities of the Company under the Securities Act unless the
rights so granted are subject in all respects to the prior rights in full of the
Holder set

                                       12
<PAGE>   72
forth herein, and are not otherwise in conflict with the provisions of this
Agreement. This Section 7(b) shall not prohibit the Company from entering into
any agreements concerning the registration of securities on Form S-8 or Form
S-4.

                  (c) [Intentionally Omitted.]

                  (d) Piggy-Back Registrations. If at any time when there is not
an effective Registration Statement covering any issued or issuable Conversion
Shares, Option Shares, Dividend Shares or Warrant Shares, and the Company shall
determine to prepare and file with the Commission a registration statement
relating to an offering for its own account or the account of others under the
Securities Act of any of its equity securities, other than on Form S-4 or Form
S-8 (each as promulgated under the Securities Act) or its then equivalents
relating to equity securities to be issued solely in connection with any
acquisition of any entity or business or equity securities issuable in
connection with stock option or other employee benefit plans, the Company shall
send to each holder of Registrable Securities written notice of such
determination and, if within thirty (30) days after receipt of such notice, any
such holder shall so request in writing (which request shall specify the
Registrable Securities intended to be disposed of by the Purchaser), the Company
will cause the registration under the Securities Act of all Registrable
Securities which the Company has been so requested to register by the holder, to
the extent requisite to permit the disposition of the Registrable Securities so
to be registered, provided that if at any time after giving written notice of
its intention to register any securities and prior to the effective date of the
registration statement filed in connection with such registration, the Company
shall determine for any reason not to register or to delay registration of such
securities, the Company may, at its election, give written notice of such
determination to such holder and, thereupon, (i) in the case of a determination
not to register, shall be relieved of its obligation to register any Registrable
Securities in connection with such registration (but not from its obligation to
pay expenses in accordance with Section 4 hereof), and (ii) in the case of a
determination to delay registering, shall be permitted to delay registering any
Registrable Securities being registered pursuant to this Section 7(d) for the
same period as the delay in registering such other securities. The Company shall
include in such registration statement all or any part of such Registrable
Securities such holder requests to be registered; provided, however, that the
Company shall not be required to register any Registrable Securities pursuant to
this Section 7(d) that are eligible for sale pursuant to Rule 144(k) of the
Securities Act. In the case of an underwritten public offering, if the managing
underwriter(s) or underwriter(s) should reasonably object to the inclusion of
the Registrable Securities in such registration statement, then if the Company
after consultation with the managing underwriter should reasonably determine
that the inclusion of such Registrable Securities, would materially adversely
affect the offering contemplated in such registration statement, and based on
such determination recommends inclusion in such registration statement of fewer
or none of the Registrable Securities of the Holder, then (x) the number of
Registrable Securities of the Holders included in such registration statement
shall be reduced pro-rata among such Holders (based upon the number of
Registrable Securities requested to be included in the registration), if the
Company after consultation with the underwriter(s) recommends the inclusion of
fewer Registrable Securities, or (y) none of the Registrable Securities of the
Holder shall be included in such registration statement, if the Company after
consultation with the underwriter(s) recommends the inclusion of none of such
Registrable Securities; provided, however, that if securities are being offered
for the account of other persons or entities as well as the Company, such
reduction shall

                                       13
<PAGE>   73
not represent a greater fraction of the number of Registrable Securities
intended to be offered by the Holder than the fraction of similar reductions
imposed on such other persons or entities (other than the Company).

                  (e) [Intentionally Omitted.]

                  (f) Specific Enforcement, Consent to Jurisdiction.

                           (i) The Company and the Purchaser acknowledge and
agree that irreparable damage would occur in the event that any of the
provisions of this Registration Rights Agreement or the Purchase Agreement were
not performed in accordance with their specific terms or were otherwise
breached. It is accordingly agreed that the parties shall be entitled to an
injunction or injunctions to prevent or cure breaches of the provisions of this
Registration Rights Agreement or the Purchase Agreement and to enforce
specifically the terms and provisions hereof or thereof, this being in addition
to any other remedy to which any of them may be entitled by law or equity.

                           (ii) Each of the Company and the Purchaser (i) hereby
irrevocably submits to the jurisdiction of the United States District Court
sitting in the City of Chicago, State of Illinois for the purposes of any suit,
action or proceeding arising out of or relating to this Agreement or the
Purchase Agreement and (ii) hereby waives, and agrees not to assert in any such
suit, action or proceeding, any claim that it is not personally subject to the
jurisdiction of such court, that the suit, action or proceeding is brought in an
inconvenient forum or that the venue of the suit, action or proceeding is
improper. Each of the Company and the Purchaser consents to process being served
in any such suit, action or proceeding by mailing a copy thereof to such party
at the address in effect for notices to it under this Agreement and agrees that
such service shall constitute good and sufficient service of process and notice
thereof. Nothing in this Section 7(f) shall affect or limit any right to serve
process in any other manner permitted by law.

                  (g) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and the Holder. Notwithstanding the foregoing, a waiver or consent to depart
from the provisions hereof with respect to a matter that relates exclusively to
the rights of a Holder and that does not directly or indirectly affect the
rights of other Holders may be given by Holders of at least a majority of the
Registrable Securities to which such waiver or consent relates; provided,
however, that the provisions of this sentence may not be amended, modified, or
supplemented except in accordance with the provisions of the immediately
preceding sentence.

                  (h) Notices. Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be in writing
and shall be deemed given and effective on the earlier of (i) the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified for notice prior to 5:00 p.m., pacific
standard time, on a Business Day, (ii) the Business Day after the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified for notice later than 5:00 p.m., pacific
standard time, on any date and earlier than 11:59

                                       14
<PAGE>   74
p.m., pacific time, on such date, (iii) the Business Day following the date of
mailing, if sent by nationally recognized overnight courier service or (iv)
actual receipt by the party to whom such notice is required to be given. The
addresses for such communications with respect to each party shall be the
address(es) for such party that are set forth in the Purchase Agreement (as the
same may be modified from time to time by such party in accordance with the
terms of the Purchase Agreement), or to such other address or addresses or
facsimile number or numbers as any such party may most recently have designated
in writing to the other parties hereto by such notice.

                  (i) Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties and their successors and permitted
assigns and shall inure to the benefit of the Holder and its successors and
assigns. The Company may not assign this Agreement or any of its rights or
obligations hereunder without the prior written consent of the Holder. The
Purchaser may assign its rights hereunder in the manner and to the Persons as
permitted under the Purchase Agreement. Notwithstanding anything to the contrary
in this Agreement, no Holder shall assign its rights under this Agreement or
otherwise transfer all or a portion of the Preferred Stock or the Registrable
Securities to any competitor of the Company, and in no event shall there be
greater than three (3) Holders which are not affiliates of the initial Holder
during the term of this Agreement.

                  (j) Assignment of Registration Rights. The rights of each
Holder hereunder, including the right to have the Company register for resale
Registrable Securities in accordance with the terms of this Agreement, shall be
automatically assignable by each Holder to any transferee of such Holder of all
or a portion of the Preferred Stock or the Registrable Securities if: (i) the
Holder agrees in writing with the transferee or assignee to assign such rights,
and a copy of such agreement is furnished to the Company within a reasonable
time after such assignment, (ii) the Company is, within a reasonable time after
such transfer or assignment, furnished with written notice of (a) the name and
address of such transferee or assignee, and (b) the securities with respect to
which such registration rights are being transferred or assigned, (iii)
following such transfer or assignment the further disposition of such securities
by the transferee or assignees is restricted under the Securities Act and
applicable state securities laws, (iv) at or before the time the Company
receives the written notice contemplated by clause (ii) of this Section, the
transferee or assignee agrees in writing with the Company to be bound by all of
the provisions of this Agreement, and (v) such transfer shall have been made in
accordance with the applicable requirements of the Purchase Agreement. In
addition, each Holder shall have the right to assign its rights hereunder to any
other Person with the prior written consent of the Company, which consent shall
not be unreasonably withheld. The rights to assignment shall apply to the
Holders (and to subsequent) successors and assigns.

                  (k) Counterparts. This Agreement may be executed in any number
of counterparts, each of which when so executed shall be deemed to be an
original and, all of which taken together shall constitute one and the same
Agreement. In the event that any signature is delivered by facsimile
transmission, such signature shall create a valid binding obligation of the
party executing (or on whose behalf such signature is executed) the same with
the same force and effect as if such facsimile signature were the original
thereof.

                                       15
<PAGE>   75
                  (l) Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware, without regard
to principles of conflicts of law thereof.

                  (m) Cumulative Remedies. The remedies provided herein are
cumulative and not exclusive of any remedies provided by law.

                  (n) Severability. If any term, provision, covenant or
restriction of this Agreement is held to be invalid, illegal, void or
unenforceable in any respect, the remainder of the terms, provisions, covenants
and restrictions set forth herein shall remain in full force and effect and
shall in no way be affected, impaired or invalidated, and the parties hereto
shall use their reasonable efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such
term, provision, covenant or restriction. It is hereby stipulated and declared
to be the intention of the parties that they would have executed the remaining
terms, provisions, covenants and restrictions without including any of such that
may be hereafter declared invalid, illegal, void or unenforceable.

                  (o) Headings. The headings herein are for convenience only, do
not constitute a part of this Agreement and shall not be deemed to limit or
affect any of the provisions hereof.

                  (p) Shares Held by the Company and its Affiliates. Whenever
the consent or approval of Holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Company or
its Affiliates (other than any Holder or transferees or successors or assigns
thereof if such Holder is deemed to be an Affiliate solely by reason of its
holdings of such Registrable Securities) shall not be counted in determining
whether such consent or approval was given by the Holders of such required
percentage and shall not be counted as outstanding.

                  (q) Notice of Effectiveness. Within two (2) business days
after the Registration Statement which includes the Registrable Securities is
ordered effective by the Commission, the Company shall deliver, and shall cause
legal counsel for the Company to deliver, to the transfer agent for such
Registrable Securities and to the Purchaser (with copies to the Holders whose
Registrable Securities are included in such Registration Statement, if other
than the Purchaser) confirmation that the Registration Statement has been
declared effective by the Commission in the form attached hereto as Exhibit A.

         IN WITNESS WHEREOF, the parties hereto have caused this Registration
Rights Agreement to be duly executed by their respective authorized persons as
of the date first indicated above.

                  Re: IPVOICE.COM, INC.

Ladies and Gentlemen:

         We are counsel to IPVoice.Com, Inc., a Nevada corporation (the
"COMPANY"), and have represented the Company in connection with that certain
Securities Purchase Agreement (the "PURCHASE AGREEMENT"), dated as of May 5,
2000, by and among the Company and the Purchaser named therein (the "HOLDER")
pursuant to which the Company issued to the Holder its Series B Seven and One
Half Percent (7.5%) Convertible Preferred Stock (the "PREFERRED STOCK") along
with warrants (the "WARRANTS") to purchase shares of the Company's common stock,
$.001 par value per share (the "COMMON STOCK"). Pursuant to the Purchase
Agreement, the Company has also entered into a Registration Rights Agreement
with the Holder (the "REGISTRATION RIGHTS AGREEMENT"), dated of even date with
the Purchase Agreement, pursuant to which the Company agreed, among other
things, to register the Registrable Securities (as defined in the Registration
Rights Agreement), including the shares of Common Stock issuable upon conversion
of the Preferred Stock and exercise of the Warrants, under the Securities Act of
1933, as amended (the "1933 ACT"). In connection with the Company's obligations
under the Registration Rights Agreement, on ____________________________ , 2000,
the Company filed a Registration Statement on Form ___ (File No. 333-__________)
(the "REGISTRATION STATEMENT") with the Securities and Exchange Commission (the
"SEC") relating to the resale of the Registrable Securities which names the
Holder as a selling stockholder thereunder.

         In connection with the foregoing, we advise you that a member of the
SEC's staff has advised us by telephone that the SEC has entered an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,
after telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

                                           Very truly yours,
                                           [COMPANY COUNSEL]

                                ESCROW AGREEMENT

         THIS ESCROW AGREEMENT (this "Agreement") is dated as of May 5, 2000,
among IPVoice.Com, Inc., a corporation organized under the laws of the State of
Nevada, U.S.A. (the "Company"), the buyer set forth on the execution page hereof
(the "Buyer") and H. GLENN BAGWELL, JR., a duly licensed attorney who practices
law in the State of North Carolina, U.S.A., as Escrow Agent (the "Escrow
Agent").

         Capitalized terms used herein and not otherwise defined herein shall
have the meanings set forth in that Securities Purchase Agreement between the
Company and the Buyer dated of even date herewith (the "Securities Purchase
Agreement").

                              W I T N E S S E T H:

         WHEREAS, the Buyer and the Company have entered into the Securities
Purchase Agreement, pursuant to which the Company has agreed to sell, and the
Buyer has agreed to purchase, at the Closing, a number of shares of Preferred
Stock along with a number of Warrants (collectively, the "Securities"); and

         WHEREAS, the Buyer and the Company have agreed to effectuate the
Closing utilizing an escrow arrangement as described in this Agreement; and

         WHEREAS, it is a condition of the Company's obligation to sell, and the
Buyer's obligation to purchase, the Securities, that this Agreement be executed
and delivered; and

         WHEREAS, the Escrow Agent is willing to act hereunder on the terms and
conditions set forth herein;

         NOW, THEREFORE, in consideration of the mutual covenants and
obligations set forth below, the parties hereto hereby agree as follows:

         1. Intentionally Omitted.

         1.1 Intentionally Omitted.

         2. ESCROW OF COMMON STOCK OF THE COMPANY.

         2.1 Intentionally Omitted.

         2.2. Escrow of Common Stock. In accordance with Section 4(h) of the
Securities Purchase Agreement, and based upon certain representations and
warranties contained in the Securities Purchase Agreement, upon registration of
the Registrable Securities, and from time to time as requested by the Buyer
thereafter, the Company shall place in trust with the Escrow Agent one or more
stock certificates representing a number of non-legended shares of Common
<PAGE>   79
Stock as specified in the Securities Purchase Agreement ("Escrow Shares"). The
Escrow Agent shall hold the Escrow Shares in certificate form or in a brokerage
account as the Escrow Agent deems appropriate to fulfill his duties under the
Securities Purchase Agreement and hereunder. None of the Escrow Shares shall be
disbursed other than in accordance with the terms of Section 4(h) of the
Securities Purchase Agreement and of the terms hereof, or in accordance with the
written instructions of both the Company and the Buyer delivered to the Escrow
Agent. In no event shall the Escrow Agent release or transfer any Escrow Shares
to any party other than to the Buyer (or another buyer) or to the Company in
accordance with this Agreement, absent express written instructions from the
Company and the Buyer to transfer Escrow Shares to a third party.

         Upon a full or partial conversion of Preferred Stock or exercise of the
Option, the Buyer shall deliver via facsimile to the Escrow Agent a copy of the
Notice of Conversion (and along with it, if applicable, the Option exercise
form). Likewise, should the Buyer exercise the Warrant in full or in part, the
Buyer shall deliver to the Escrow Agent a copy of such exercise form. The Escrow
Agent shall use its reasonable best efforts to cause the delivery from escrow to
the Buyer (in accordance with the Buyer's written instructions to the Escrow
Agent, and via electronic transfer or otherwise) of the number of shares of
Common Stock specified in the Notice of Conversion (and Option exercise notice,
if applicable) or the Warrant exercise form within three (3) business days after
receipt of such Notice of Conversion (and Option exercise notice) or Warrant
exercise form. The Escrow Agent shall not be responsible for any breach by the
Company of its obligation to timely deliver sufficient Escrow Shares to effect a
conversion or exercise.

         Upon Buyer's receipt of all Common Stock due upon conversion of all of
the Preferred Stock issued to the Buyer, including also any Option Shares to be
issued upon exercise of the Option, or upon exercise of the Warrant, the Buyer
shall inform the Escrow Agent in writing that the requirements of the Securities
Purchase Agreement with respect to the Preferred Stock have been satisfied. The
Company shall instruct the Escrow Agent in writing as to the return to the
Company of the remaining Escrow Shares, and the Escrow Agent shall as soon as
practicable return such remaining Escrow Shares in accordance with the Company's
instructions. Thereafter the Escrow Agent shall have no further obligation to
any party with respect to the Escrow Shares, whether those delivered to the
Buyer or those returned to the Company.

         2.3 Controversies. If any controversy arises between two or more of the
parties hereto, or between any of the parties hereto and any person not a party
hereto, as to whether or not or to whom the Escrow Agent shall deliver the
Escrow or any portion thereof or as to any other matter arising out of or
relating to this Escrow Agreement, the Escrow Agent shall not be required to
determine the same and need not make any delivery of the Escrow concerned or any
portion thereof but may retain the same until the rights of the parties to the
dispute shall have been finally determined by agreement or by final judgment of
a court of competent jurisdiction after all appeals have been finally determined
(or the time for further appeals has expired without an appeal having been
made). The Escrow Agent shall deliver that portion of the Escrow concerned
covered by such agreement or final order within five (5) days after the Escrow
Agent receives a copy thereof. The Escrow Agent shall assume that no such
controversy has arisen unless and until it receives written notice from the
Buyer or the Company

                                       2
<PAGE>   80
that such controversy has arisen, which refers specifically to this Agreement
and identifies the adverse claimants to the controversy.

         2.4 No Other Disbursements. No portion of the Escrow, whether cash,
securities (including Escrow Shares) or documentation shall be disbursed or
otherwise delivered or transferred except in accordance with this Section 2,
Section 4 or Section 5.1(b), in accordance with the written instructions of both
the Company and the Buyer, or as required by applicable law. Without limiting
the foregoing, neither Escrow Agent nor the Buyer shall be entitled to any right
of offset against the Escrow or otherwise entitled to receive any portion of the
Escrow.

         3. ESCROW AGENT. The acceptance by the Escrow Agent of his duties
hereunder is subject to the following terms and conditions, which the parties to
this Agreement hereby agree shall govern and control with respect to the rights,
duties, liabilities and immunities of the Escrow Agent:

         3.1 The Escrow Agent shall not be responsible or liable in any manner
whatever for the sufficiency, correctness, genuineness or validity of any cash,
investments or other amounts deposited with or held by the Escrow Agent.

         3.2 The Escrow Agent shall be protected in acting upon any written
notice, certificate, instruction, request or other paper or document believed by
the Escrow Agent to be genuine and to have been signed or presented by the
proper party or parties.

         3.3 The Escrow Agent shall not be liable for any act done hereunder
except in the case of the Escrow Agent's willful misconduct or bad faith.

         3.4 The Escrow Agent shall not be obligated or permitted to investigate
the correctness or accuracy of any document or to determine whether or not the
signatures contained in said documents are genuine or to require documentation
or evidence substantiating any such document or signature.

         3.5 The Escrow Agent shall have no duties as Escrow Agent except those
that are expressly set forth herein, and in any modification or amendment
hereof; provided, however, that no such modification or amendment hereof shall
affect his duties unless it shall have given his written consent thereto. The
Escrow Agent shall not be prohibited from owning an equity interest in the
Company, the Buyer, another buyer, any of their respective subsidiaries or any
third party that is in any way affiliated with or conducts business with either
the Company, the Buyer or another buyer.

         3.6 The Company and the Buyer specifically acknowledge that the Escrow
Agent is a practicing attorney in Raleigh, North Carolina U.S.A., and may have
worked with or be affiliated with the Company, the Buyer, or affiliates of
either of them on other transactions, and that they and each of them has
specifically requested that the Escrow Agent draft the documents for the said
transactions and act as Escrow Agent with respect to the said transactions. Each
party represents that it has retained legal and other counsel of its choosing
with respect to the transactions contemplated herein and in the Securities
Purchase Agreement, and is satisfied in its sole

                                       3
<PAGE>   81
discretion with the form and content of the documentation drafted by the Escrow
Agent, as the same has been approved prior to closing by the parties and their
respective counsel. The Escrow Agent may own an equity interest in the Company
and/or may be an equity owner of the Buyer or another buyer, and may increase or
sell any such interest, so long as in accordance with any and all applicable
law. The said parties hereby waive any objection to the Escrow Agent so acting
based upon conflict of interest or lack of impartiality. The Escrow Agent agrees
to act impartially and in accordance with the terms of this Agreement and with
the parties' respective instructions, so long as they are not in conflict with
the terms of this Agreement.

         4. TERMINATION. This Agreement shall terminate on the earlier of (a)
the date on which the Escrow and all other escrowed documents and things
described herein shall have been fully disbursed in accordance with the terms
and conditions of this Agreement, (b) any other date agreed to by the Buyer and
the Company, or (c) the next business day after the expiration of the last of
the Warrants to be issued by the Company in accordance with the terms of the
Securities Purchase Agreement.

         5. MISCELLANEOUS.

         5.1 Indemnification of Escrow Agent.

         (a) The Company and the Buyer each agree, jointly and severally, to
indemnify the Escrow Agent for, and to hold him harmless against, any loss
incurred without willful misconduct or bad faith on the Escrow Agent's part,
arising out of or in connection with the administration of this Agreement,
including the costs and expenses of defending himself against any claim or
liability in connection with the exercise or performance of any of his powers or
duties hereunder. This indemnification shall not apply to a party with respect
to a direct claim against the Escrow Agent by such party alleging in good faith
a breach of this Agreement by the Escrow Agent, which claim results in a final
non-appealable judgment against the Escrow Agent with respect to such claim.

         (b) In the event of any dispute as to the nature of the rights or
obligations of the Buyer, the Company or the Escrow Agent hereunder, the Escrow
Agent may at any time or from time to time interplead, deposit and/or pay all or
any part of the Escrow Funds with or to a court of competent jurisdiction
sitting in Wake County, North Carolina or in any appropriate federal court, in
accordance with the procedural rules thereof. The Escrow Agent shall give notice
of such action to the Company and the Buyer. Upon such interpleader, deposit or
payment, the Escrow Agent shall immediately and automatically be relieved and
discharged from all further obligations and responsibilities hereunder,
including the decision to interplead, deposit or pay such funds.

         5.2 Amendments. This Agreement may be modified or amended only by a
written instrument executed by each of the parties hereto.

         5.3 Notices. All communications required or permitted to be given under
this Agreement to any party hereto shall be sent by first class mail or
facsimile to such party at the address, except in the case of the Escrow Agent,

benefit of the parties hereto and their respective successors and assigns;

Agreement.

         Re:      IPVoice.Com, Inc.

Gentlemen:

                  We have acted as counsel to IPVoice.Com, Inc., a Nevada
corporation (the "Company"), in connection with your purchase of Series B
Convertible Preferred Stock (the "Preferred Stock"), along with certain warrants
(the "Warrants"), in accordance with the terms of that Securities Purchase
Agreement dated as of May ___, 2000 (the "Agreement") between the Company and
________________ (the "Investor"), (ii) the Registration Rights Agreement dated
as of the date hereof (the "Registration Rights Agreement") between the Company
and the Investor, and (iii) the Escrow Agreement dated as of the date hereof
(the "Escrow Agreement") among the Company, the Investor and H. Glenn Bagwell,
Jr., Esq., as escrow agent. Capitalized terms used herein but not otherwise
defined herein shall have the meanings set forth in the Agreement.

                  In connection with rendering this opinion, we have examined
the Agreement, the Registration Rights Agreement, the Escrow Agreement, the
Certificate of Designations as filed (or as it will be filed prior to the
Closing) and the form of the Warrants (collectively, the "Transaction
Documents"), as well as the Company's Articles of Incorporation, as amended
("Articles"), and Bylaws and the resolutions of the Board of Directors of the
Company approving the transactions contemplated by the Transaction Documents.
<PAGE>   85
                  We have also made such examination of law and have examined
originals or copies, certified or otherwise, of such corporate records and
documents of the Company, such agreements, certificates of officers or
representatives of the Company, and such other records, certificates, including
certificates of public officials, and documents as we have deemed relevant and
necessary as a basis for the opinions hereinafter expressed. In such
examination, we have assumed the genuineness of all signatures, the authenticity
of all documents submitted to us as originals and the conformity with authentic
original documents of all documents submitted to us as copies. As to any facts
relevant to the opinions expressed below, we have relied upon certificates and
written and/or oral representations of officers of the Company (including the
representations of the Company set forth in the Transaction Documents) and
public officials. We have also assumed that the representations and warranties
of the Investor as set forth in the Transaction Documents are true and correct
as of the date hereof. All references herein to contracts, instruments or other
documents of the Company are limited to such documents as have been provided to
us by the Company or of which we have actual knowledge after due inquiry of the
Company and its officers. As to our opinion in paragraphs 2, 3, and 7 set forth
below, we have examined only resolutions of the Board of Directors of the
Company relating to such share issuances and our opinion set forth in such
paragraphs is limited thereto. We have not examined or reviewed any
communication, instrument, agreement, document or other item or conducted any
independent inquiry or investigation of any matter except as otherwise expressly
set forth above. We have also assumed that the Agreement and the other
Transaction Documents have been executed and delivered by and are binding on
each of the parties thereto.

                  The opinions expressed below with respect to compliance with
certain statutes, rules and regulations are based upon a review of those
statutes, rules and regulations that, in our experience, are applicable to
transactions of the type contemplated by the Agreement and to businesses such as
the Company's. Our opinion as to the good standing of the Company in Nevada set
forth in the first sentence of paragraph 1 below is based solely upon our
examination of a certificate of good standing dated April__, 2000 provided by
the Secretary of State of Nevada, and such opinion is given solely as of such
date.

                  In connection with our opinion with respect to pending
litigation and existing orders, contracts, injunctions, judgements and decrees
set forth in paragraph 5 below we have not undertaken searches of the dockets of
any court of any jurisdiction, nor conducted a judgment, lien, litigation or
similar search and have relied upon certificates and written or oral
representations of officers of the Company.

                  We express no opinion respecting the enforceable nature of the
Agreement, the other Transaction Documents, or any document or instrument
executed pursuant thereto or in connection therewith, insofar as the enforceable
nature thereof, or any right, power, privilege, remedy or interest intended to
be created thereunder, may be limited (i) by applicable bankruptcy, insolvency,
moratorium, fraudulent conveyance, reorganization or other laws or judicial
decisions affecting any rights, powers, privileges, remedies or interests of
creditors generally, (ii) by rules or principles of equity affecting the
<PAGE>   86
enforcement of obligations generally, whether at law, in equity or otherwise,
(iii) by the exercise of the discretionary powers of any court or other
authority before which may be brought any proceeding seeking equitable or other
remedies, including, without limitation, specific performance, injunctive relief
and indemnification or (iv) insofar as rights to indemnity and/or contribution
are concerned, by federal or state securities laws or the public policy
underlying such laws.

                  Our opinion is limited to the date hereof and we do not in any
event undertake to advise you of any facts or circumstances occurring or coming
to our attention subsequent to the date hereof.

                  Where reference is made in this opinion to matters within or
to our knowledge, to the best of our knowledge, or to facts or circumstances
known to us or which have come to our attention, such reference means the actual
knowledge of those attorneys in our firm who have given substantive attention to
the preparation of the Agreement and other Transaction Documents and those
attorneys in our firm who, from time to time, have given substantive attention
to the general corporate and securities matters for which our firm has been
engaged by the Company, their review of documents in connection with this
engagement and the general corporate and securities matters for which our firm
has been engaged by the Company, and inquiries of officers of the Company,
without, however, independent investigation of any matter unless expressly set
forth herein.

                  We call your attention to the fact that we are counsel
admitted to practice in the State of Arizona, and we do not express any opinion
with respect to the applicable laws, or the effect or applicability of the laws,
of any jurisdiction other than those of the State of Arizona, the Delaware
General Corporation Law, the General Corporation Law of the State of Nevada, and
the securities laws of the United States of America. In particular, but without
limitation, we do not express any opinion with respect to the Blue Sky or
securities laws of any State or other jurisdiction (other than the federal
securities laws of the United States of America), or any law relating
specifically to telecommunications or patents, trademarks or other intellectual
property rights. The Securities Purchase Agreement, the Warrants and the
Registration Rights Agreement state that they are to be governed by the laws of
the State of Delaware, and the Escrow Agreement states that it is to be governed
by the laws of the State of North Carolina. We are not familiar with those laws,
other than the Delaware General Corporation Law, and render no opinion about
them other than the Delaware General Corporation Law. For purposes of our
opinion we have assumed, with your consent, that the laws of Delaware, other
than the Delawares General Corporation Law, and North Carolina are identical in
all relevant respects to the laws of Arizona. We express no opinion about the
reasonableness of this assumption.

                  Based upon and subject to the foregoing, we are of the opinion
that:

                  1. The Company is a corporation organized, validly existing
and in good standing under the laws of the State of Nevada and has all requisite
power and authority to carry on its business and to own, lease and operate its
properties and assets.
<PAGE>   87
The Company is duly qualified as a foreign corporation to do business and is in
good standing in every jurisdiction in which the Company owns or leases
property, other than those in which the failure so to qualify would not have a
Material Adverse Effect.

                  2. The Company has the requisite corporate power and authority
to enter into and perform its obligations under the Agreement and the other
Transaction Documents, to file the Certificate of Designations and to issue the
Preferred Stock and the Warrants, and the shares of Common Stock underlying the
Preferred Stock and the Warrants. The execution and delivery of the Agreement,
and the execution, issuance and delivery of the Transaction Documents by the
Company and the consummation by it of the transactions contemplated thereby have
been duly authorized by all necessary corporate action and no further consent or
authorization of the Company or its Board of Directors or stockholders is
required except for approval of the stockholders of the Company with respect to
the issuance by the Company of more than 19.99% of the outstanding shares of
Common Stock that may be required by the NASDAQ Market (if applicable). The
Agreement and the other Transaction Documents have been duly executed and
delivered, and the Warrants have been duly executed, issued and delivered by the
Company and each of the Agreement and the other Transaction Documents
constitutes valid and binding obligations of the Company enforceable against the
Company in accordance with their respective terms.

                  3. Subject to the Company maintaining the requisite number of
authorized shares of Preferred Stock and of Common Stock, the execution,
delivery and performance of the Agreement and the other Transaction Documents by
the Company and the consummation by the Company of the transactions contemplated
thereby, including, without limitation, the issuance of the Securities, do not
and will not (i) result in a violation of the Company's Articles or Bylaws, or
(ii) to our knowledge, conflict with, or constitute a material default (or an
event that with notice or lapse of time or both would become a default) under,
or give to others any rights of termination, amendment, acceleration or
cancellation of, any material agreement, indenture, instrument or any "lock-up"
or similar provision of any underwriting or similar agreement to which the
Company is a party, except for such conflicts, defaults, terminations,
amendments, accelerations and cancellations as would not, individually or in the
aggregate, have a Material Adverse Effect.

                  4. The issuance of the Securities in accordance with the
Agreement will be exempt from registration under the Securities Act of 1933, as
amended. When so issued against payment in full of the agreed upon consideration
therefor, the Securities will be duly and validly issued, fully-paid and
nonassessable, and free of any liens, encumbrances and preemptive or similar
rights contained in the Company's Articles or Bylaws or, to our knowledge, in
any agreement to which the Company is party.

                  5. To our knowledge, except as disclosed in the Financial
Statements or in a Schedule to the Agreement, there are no claims, actions,
suits, proceedings or investigations that are pending against the Company or its
properties, nor has the Company received any written threat of any such claims,
actions, suits, proceedings or investigations.
<PAGE>   88
To our knowledge, the Company is not a party to or subject to the provisions of
any order, writ, injunction, judgment or decree of any court or government
agency or instrumentality.

                  6. To our knowledge, other than as referenced in Schedule 3(c)
to the Agreement, there are no outstanding options, warrants, calls or
commitments of any character whatsoever relating to, or securities, rights or
obligations convertible into or exchangeable for, or giving any right to
subscribe for or acquire any shares of Common Stock or contracts, commitments,
understanding, or arrangements by which the Company is or may become bound to
issue additional shares of Common Stock, or securities or rights convertible or
exchangeable into shares of Common Stock.

                  7. The issuance of the Securities will not violate the
applicable listing agreement between the Company and any securities exchange or
market on which the Company's securities are listed.

                  This opinion is rendered solely to the Investor in connection
with the transactions contemplated by the Agreement and only the Investor is
entitled to rely hereon. This opinion may not be used or relied on by the
Investor for any other purpose, or by any other person, firm, corporation or
entity for any purpose, without our prior written consent.

                                                  Very truly yours,

                                                  [NAME OF LAW FIRM OR ATTORNEY]<PAGE>   1
                                                                   EXHIBIT 10.47

                          SECURITIES PURCHASE AGREEMENT

         THIS SECURITIES PURCHASE AGREEMENT (this "Agreement"), is made as of
May 5, 2000, by and between IPVoice.Com, Inc., a corporation organized under the
laws of the State of Nevada, U.S.A., with headquarters located at 5050 North
19th Avenue, Suite 416, Phoenix, Arizona 85015 (the "Company") and the purchaser
named on the signature page hereof (the "Buyer").

                                    RECITALS

         A. The Company and the Buyer are executing and delivering this
Agreement in reliance upon the exemption from securities registration afforded
by the provisions of Regulation D ("Regulation D") as promulgated by the United
States Securities and Exchange Commission (the "SEC") under the Securities Act
of 1933, as amended (the "1933 Act") and Section 4(2) under the 1933 Act;

         B. The Buyer desires to purchase from the Company, and the Company
desires to sell to the Buyer, for the amounts and upon the terms and conditions
stated in this Agreement, in a closing (the "Closing") as herein described,
certain of the Company's convertible preferred stock as listed and described in
Recital B(i) immediately below, and certain warrants as listed and described in
Recital B(ii) below.

            (i)  At the Closing (the "Closing"), 1,250 shares of the Company's
                 Series B Convertible Preferred Stock (the "Preferred Stock").
                 The designation, rights, preferences and other terms and
                 provisions of the Preferred Stock are set forth in the
                 Certificate of Designation of the Relative Rights and
                 Preferences of the Series B Convertible Preferred Stock of
                 IPVoice.Com, Inc., attached hereto as Exhibit A (the
                 "Certificate of Designations"). The Preferred Stock may be
                 converted into common stock of the Company, $.001 par value per
                 share ("Common Stock"), upon the terms and conditions hereof
                 and upon the terms and conditions of the Certificate of
                 Designations. The Preferred Stock also contains an option (the
                 "Option") to purchase additional Common Stock ("Option Shares")
                 as described in the Certificate of Designations. The purchase
                 price for the Preferred Stock sold pursuant to this Agreement
                 shall be as stated in Section 1(a) below. The total aggregate
                 number of shares of Preferred Stock to be issued and sold by
                 the Company at this Closing is two thousand five hundred
                 (2,500), and the purchase price for each share of Preferred
                 Stock is $1,000.00, all in accordance with the terms of this
                 Agreement and of the Certificate of Designations.

            (ii) At the Closing, as additional consideration for Buyer's
                 purchase of the Preferred Stock, a warrant (the "Warrants") to
                 purchase 125,000 shares of Common Stock at a purchase price per
                 share equal to one hundred twenty percent (120%) of the lowest
                 of the closing bid prices for the Common Stock for the five (5)
                 trading days prior to the Closing Date (defined below), which
                 Warrants must be exercised if at all within five (5) years
                 after the date of

                issuance. The Warrants shall be substantially in the form
                attached hereto as Exhibit B.

         The Common Stock into which the Preferred Stock may (in accordance with
the terms of the Certificate of Designations) be convertible shall be referred
to herein as the "Conversion Shares." Certain shares of Common Stock may (at the
Company's option as described in the Certificate of Designations) be issued to
the Buyer in payment of dividends (the "Dividend Shares"). The Common Stock
received upon exercise of the Warrants shall be referred to as the "Warrant
Shares." The Conversion Shares, the Option Shares, the Dividend Shares (if any),
the Warrants and the Warrant Shares may be collectively referred to herein as
the "Securities."

         C. Contemporaneously with the execution and delivery of this Agreement,
the parties hereto are executing and delivering a Registration Rights Agreement
(the "Registration Rights Agreement") substantially in the form of Exhibit C
attached hereto pursuant to which the Company has agreed to provide certain
registration rights with respect to the Securities under the 1933 Act and the
rules and regulations promulgated thereunder, and applicable state securities
laws.

                                   AGREEMENTS

         NOW, THEREFORE, in consideration of their respective promises contained
herein and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged by the parties, the Company and the Buyer hereby
agree as follows:

         1. PURCHASE AND SALE OF SECURITIES.

         a. Purchase. At the Closing, the Buyer shall purchase from the Company,
and the Company shall sell to the Buyer, 1,250 shares of Preferred Stock and the
Warrants. The purchase price (the "Purchase Price") for the Preferred Stock and
the Warrants purchased by the Buyer shall be $1,250,000.00.

         b. The Closing. Subject to the terms of this Agreement, the date of the
Closing (the "Closing Date") shall be May 22, 2000. The Purchase Price shall be
delivered to an escrow agent (the "Buyer's Agent") of the Buyer's choosing, to
be held by the Buyer's Agent pending the parties' completion of the items
required pursuant to Sections 6 and 7 hereof. On or before the Closing Date, the
Company shall deliver the original certificate(s) representing the Preferred
Stock along with the Warrants (or a facsimile of the signature pages thereof,
with the originals to follow via express courier within one (1) business day)
being purchased at the Closing, duly issued, authorized and executed by the
authorized officers on behalf of the Company, to the Buyer.

         c. Form of Payment. The Buyer shall pay the Purchase Price for the
Securities purchased at the Closing by wire transfer of immediately available
funds in United States Dollars, to be held by the Buyer's Agent against delivery
to the Buyer or the Buyer's Agent of the appropriate number of shares of duly
authorized and issued Preferred Stock and Warrants being purchased by the Buyer
hereunder at such Closing. The Buyer's Agent shall be responsible for

                                       2
<PAGE>   3
delivery of the Purchase Price to the Company and the Preferred Stock and
Warrants to the Buyer in accordance with the terms of the Escrow Agreement and
with the instructions of the said parties.

         2. BUYER'S REPRESENTATIONS AND WARRANTIES.

         The Buyer understands, agrees with, and represents and warrants to the
Company with respect to its purchase hereunder, that:

         a. Investment Purposes; Compliance With 1933 Act. The Buyer is
purchasing the Securities for its own account for investment only and not with a
view towards, or in connection with, the public sale or distribution thereof,
except pursuant to sales registered under or exempt from the 1933 Act and
applicable state securities laws. The Buyer is not purchasing the Securities for
the purpose of covering short sale positions in the Common Stock established on
or prior to the Closing Date. The Buyer agrees to offer, sell or otherwise
transfer the Securities only (i) in accordance with the terms of this Agreement,
the Certificate of Designations and the Warrants, as applicable, and (ii)
pursuant to registration under the 1933 Act or to an exemption from registration
under the 1933 Act and any other applicable securities laws. The Buyer does not
by its representations contained in this Section 2(a) agree to hold the
Securities for any minimum or other specific term and reserves the right to
dispose of the Securities at any time pursuant to a registration statement or in
accordance with an exemption from registration under the 1933 Act, in all cases
in accordance with applicable state and federal securities laws. The Buyer
understands that it shall be a condition to the issuance of the Conversion
Shares, the Option Shares, the Warrant Shares and the Dividend Shares (if any)
that the Conversion Shares, the Option Shares, the Warrant Shares and the
Dividend Shares (if any) be and are subject to the representations set forth in
this Section 2(a).

         b. Accredited Investor Status. The Buyer is an "accredited investor" as
that term is defined in Rule 501 (a) of Regulation D. The Buyer has such
knowledge and experience in financial and business matters that it is capable of
evaluating the merits and risks of an investment made pursuant to this
Agreement. The Buyer is aware that it may be required to bear the economic risk
of an investment made pursuant to this Agreement for an indefinite period of
time, and is able to bear such risk for an indefinite period.

         c. Reliance on Exemptions. The Buyer understands the Securities are
being offered and sold to it in reliance on specific exemptions from the
registration requirements of the applicable United States federal and state
securities laws and that the Company is relying upon the truth and accuracy of,
and the Buyer's compliance with, the representations, warranties,
acknowledgments, understandings, agreements and covenants of the Buyer set forth
herein in order to determine the availability of such exemptions and the
eligibility of the Buyer to acquire the Securities.

         d. 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 that have
been requested by the Buyer. The Buyer and its advisors, if any, have been
afforded the opportunity to ask all such questions of the Company as they have
in their discretion deemed advisable. The Buyer understands that its investment
in the Securities involves a high degree of risk. The Buyer has sought such
accounting, legal and tax

                                       -3-
<PAGE>   4
advice as it has considered necessary to an informed investment decision with
respect to the investment made pursuant to this Agreement.

         e. No Government Review. The Buyer understands that no United States
federal or state agency or any other government or governmental agency has
approved or made any recommendation or endorsement of the Securities or the
fairness or suitability of the investment in the Securities, nor have such
authorities passed upon or endorsed the merits of the offering of the
Securities.

         f. Transfer or Resale. The Buyer understands that: (i) except as
provided in the Registration Rights Agreement, the Securities have not been and
are not being registered under the 1933 Act or any state securities laws, and
may not be offered for sale, sold, assigned or transferred unless either (a)
subsequently registered thereunder or (b) the Buyer shall have delivered to the
Company an opinion by counsel reasonably satisfactory to the Company, in form,
scope and substance reasonably satisfactory to the Company, to the effect that
the securities to be sold, assigned or transferred may be sold, assigned or
transferred pursuant to an exemption from such registration, (ii) any sale of
such securities made in reliance on Rule 144 (as hereafter defined) may be made
only in accordance with the terms of Rule 144 and further, if Rule 144 is not
applicable, any resale of such securities under circumstances in which the
seller (or the person though whom the sale is made) may be deemed to be an
underwriter (as that term is defined in the 1933 Act) may require compliance
with some other exemption under the 1933 Act or the rules and regulations of the
SEC thereunder and applicable state securities laws, and (iii) neither the
Company nor any other person is under any obligation to register such securities
under the 1933 Act or any state securities laws or to comply with the terms and
conditions of any exemption thereunder (in each case, other than pursuant to
this Agreement or the Registration Rights Agreement).

         g. Legend. The Buyer understands that the Preferred Stock, the
Warrants, and until such time as the Conversion Shares, the Option Shares, the
Warrant Shares and the Dividend Shares (if any) (collectively, the "Registrable
Securities"), have been registered under the 1933 Act as contemplated by the
Registration Rights Agreement or otherwise may be sold by the Buyer pursuant to
Rule 144 (as amended, or any applicable rule which operates to replace said
Rule) promulgated under the 1933 Act ("Rule 144"), the stock certificates
representing the Registrable Securities will bear a restrictive legend (the
"Legend") in substantially the following form:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE "ACT"), OR APPLICABLE STATE SECURITIES LAWS
(COLLECTIVELY, THE "LAWS"). THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND
MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF
EITHER (I) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE
LAWS, OR (II) AN OPINION OF COUNSEL PROVIDED TO THE ISSUER IN FORM, SUBSTANCE
AND SCOPE REASONABLY ACCEPTABLE TO THE ISSUER TO THE EFFECT THAT REGISTRATION IS
NOT REQUIRED UNDER THE LAWS DUE TO AN AVAILABLE EXCEPTION TO OR EXEMPTION FROM
THE REGISTRATION REQUIREMENTS OF THE LAWS.

                                       -4-
<PAGE>   5
         The Legend shall be removed and the Company will issue Common Stock
certificates without the Legend to the holder of the applicable Preferred Stock
or any Registrable Securities upon which the Legend is stamped, in accordance
with Section 5(b).

         h. Authorization; Enforcement. This Agreement, the Registration Rights
Agreement and the Escrow Agreement have been duly and validly authorized,
executed and delivered by the Buyer and are each and collectively valid and
binding agreements of the Buyer enforceable in accordance with their terms,
subject as to enforceability to general principles of equity and to bankruptcy,
insolvency, moratorium, and other similar laws affecting the enforcement of
creditors' rights generally.

         3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         The Company understands, agrees with, and represents and warrants to
the Buyer that:

         a. Organization and Qualification. The Company is a corporation duly
organized and existing in good standing under the laws of the jurisdiction in
which it is incorporated, except as would not have a Material Adverse Effect (as
defined below), and has the requisite corporate power to own its properties and
to carry on its business as now being conducted. The Company is duly qualified
as a foreign corporation to do business and is in good standing in every
jurisdiction in which the nature of the business conducted by it makes such
qualification necessary and where the failure so to qualify would have a
Material Adverse Effect. "Material Adverse Effect" means any material adverse
effect on the operations, properties or financial condition of the Company taken
as a whole. The Common Stock is eligible to trade and is listed for trading on
the OTC Bulletin Board Market. The Company has received no notice, either
written or oral, with respect to the continued eligibility of the Common Stock
for such listing, and the Company has maintained all requirements for the
continuation of such listing, and the Company does not reasonably anticipate,
based upon conditions currently existing and reasonably forecasted that the
Common Stock will be delisted from the OTC Bulletin Board Market for the
reasonably foreseeable future. The Company has complied or will timely comply
with all requirements of the National Association of Securities Dealers and the
OTC Bulletin Board Market with respect to the issuance of the Securities.

         b. Authorization; Enforcement. (i) The Company has the requisite
corporate power and authority to enter into and perform this Agreement, the
Registration Rights Agreement and the Escrow Agreement, to issue and sell the
Preferred Stock and the Registrable Securities in accordance with the terms
hereof, and to perform its obligations under the Certificate of Designations in
accordance with the requirements of the same, (ii) the execution, delivery and
performance of the Company's obligations under this Agreement, the Certificate
of Designations, the Warrants, the Registration Rights Agreement and the Escrow
Agreement by the Company and the consummation by it of the transactions
contemplated hereby and thereby 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, (iii) this Agreement, the
Registration Rights Agreement, the Escrow Agreement and, on the Closing Date,
the Preferred Stock and Warrants sold at the Closing, have been duly and validly
authorized, executed and delivered by the Company, and (iv) this Agreement, the
Preferred Stock (when issued), the Warrants (when issued), the Registration

                                      -5-
<PAGE>   6
Rights Agreement and the Escrow Agreement constitute the valid and binding
obligations of the Company enforceable against the Company in accordance with
their respective terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or
similar laws relating to, or affecting, generally, the enforcement of creditors'
rights and remedies or by other equitable principles of general application. The
Company (and its legal counsel) has examined this Agreement and is satisfied in
its sole discretion that, assuming the accuracy of the representations of the
Buyer contained in Section 2 of this Agreement, this Agreement and the
accompanying Exhibits, Schedules and the Addenda, if any, are in accordance with
Regulation D and the 1933 Act and are effective to accomplish the purposes set
forth herein and therein.

         c. Capitalization. As of May 1, 2000, the authorized common stock of
the Company consisted of 50,000,000 shares of Common Stock of which 17,303,758
shares were issued and outstanding. As of May 1, 2000, the authorized preferred
stock of the Company consisted of 10,000,000 preferred shares, of which 1,150
senior convertible preferred shares ("Series A Preferred Shares") were issued
and outstanding. There are no other authorized classes of common stock, nor are
there authorized or outstanding any other classes of preferred stock or other
equity or debt securities other than the Preferred Stock. All of such
outstanding shares of Common Stock and Series A Preferred Shares have been
validly issued and are fully paid and nonassessable. No shares of Common Stock
nor the Series A Preferred Shares are subject to preemptive rights or any other
similar rights or any liens or encumbrances. Except for the Series A Preferred
Shares and the Company's promissory notes issued in connection therewith, the
Securities issued pursuant to this Agreement and as disclosed in Schedule 3(c)
(attached if applicable), as of the effective date of this Agreement, (i) there
are no outstanding options, warrants, scrip, rights to subscribe to, calls or
commitments of any character whatsoever relating to, or securities or rights
convertible into, 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 outstanding debt securities, and
(iii) 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 1933 Act (except as provided herein, in Schedule 3 and in
the Registration Rights Agreement). If requested by the Buyer, the Company has
furnished to the Buyer, and the Buyer acknowledges receipt of same by its
signature hereafter, true and correct copies of the Company's Articles of
Incorporation, as amended, as in effect on the date hereof ("Articles of
Incorporation"), and the Company's Bylaws, as in effect on the date hereof (the
"Bylaws").

         d. Issuance of Securities. The Registrable Securities are all duly
authorized and reserved for issuance, and in all cases upon issuance shall be
validly issued, fully paid and non-assessable, free from all taxes, liens and
charges with respect to the issue thereof, and will not be subject to preemptive
rights or other similar rights of stockholders of the Company.

         e. Acknowledgment Regarding Buyer's Purchase of the Securities. The
Company acknowledges and agrees that the Buyer is not acting as financial
advisor to or fiduciary of the Company (or in any similar capacity with respect
to this Agreement or the transactions contemplated hereby), that this Agreement
and the transactions contemplated hereby, and the relationship between

                                      -6-
<PAGE>   7
the Buyer and the Company, are and will be considered "arms-length"
notwithstanding any other or prior agreements or nexus between the Buyer and the
Company, whether or not disclosed, and that any statement made by the Buyer, or
any of its representatives or agents, in connection with this Agreement and the
transactions contemplated hereby is not advice or a recommendation, is merely
incidental to the Buyer's purchase of the Securities and has not been relied
upon in any way by the Company, its officers or directors. The Company further
represents to the Buyer that the Company's decision to enter into this Agreement
and the transactions contemplated hereby have been based solely upon an
independent evaluation by the Company, its officers and directors.

         f. No Integrated Offering. Neither the Company, nor any of its
affiliates, nor any person acting on its or their behalf, has directly or
indirectly made any offers or sales of any security or solicited any offers to
buy any security under circumstances which would prevent the parties hereto from
consummating the transactions contemplated hereby pursuant to an exemption from
registration under the 1933 Act and specifically in accordance with the
provisions of Regulation D. The transactions contemplated hereby are exempt from
the registration requirements of the 1933 Act, assuming the accuracy of the
representations and warranties contained herein of the Buyer.

         g. No Conflicts. The execution, delivery and performance of this
Agreement by the Company and the consummation by the Company of the transactions
contemplated hereby will not (i) result in a violation of the Articles of
Incorporation or Bylaws or (ii) conflict with, or constitute a default (or an
event which with notice or lapse of time or both would 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 result in a violation of any law, rule,
regulation, order, judgment or decree (including federal and state securities
laws 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). Except as set forth in Schedule 3(g)
(attached if applicable), neither the Company nor any of its subsidiaries is in
violation of its Articles of Incorporation 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, would put the Company
or any of its subsidiaries in default) under, nor has there occurred any event
giving others (with notice or lapse of time or both) 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, except
for possible defaults or rights as would not, in the aggregate or individually,
have a Material Adverse Effect. The business of the Company and its subsidiaries
is not being conducted, and shall not be conducted so long as the Buyer owns any
of the Securities, in violation of any law, ordinance or regulation of any
governmental entity, except for possible violations which neither singly or in
the aggregate would have a Material Adverse Effect. Except as specifically
contemplated by this Agreement and as required under the 1933 Act and any
applicable state securities laws (any of which exceptions are set forth in
Schedule 3(g)), the Company is not required to obtain any consent, authorization
or order of, or make any filing or registration with, any court or governmental
agency (except for such consents, authorizations or orders as would not have a
Material Adverse Effect) in order for it to execute, deliver or perform any of
its obligations under this Agreement, the Certificate of Designations, the
Warrants, the

                                      -7-
<PAGE>   8
Registration Rights Agreement or the Escrow Agreement in accordance with the
terms hereof and thereof, or to perform its obligations with respect to the
Preferred Stock exactly as described in the Certificate of Designations (once
the Preferred Stock is issued), and with respect to the Warrants exactly as
described in the Warrants (once issued).

          h. SEC Documents; Financial Statements. Except as disclosed on
Schedule 3(h) hereof (attached if applicable), since at least November 3, 1999
(the date on which the Company filed its initial filing, Form 10SB12(g), with
the SEC), the Company has timely filed all reports, schedules, forms, statements
and other documents to be filed by it with the SEC pursuant to the reporting
requirements of the Securities Exchange Act of 1934, as amended (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 as
the "SEC Documents"). The Company has delivered to the Buyer as requested by the
Buyer true and complete copies of the SEC Documents, except for such exhibits,
schedules 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 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 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 exclude
footnotes or may be condensed or summary statements or are otherwise subject to
normal year-end adjustments) and fairly present in all material respects the
financial position of the Company as of the dates thereof and the results of its
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end audit adjustments). No other
information provided by or on behalf of the Company to the Buyer (including the
information referred to in Section 2(d) of this Agreement) contains any untrue
statement of a material fact or omits to state any material fact necessary in
order to make the statements therein, in the light of the circumstance under
which they are or were made, not misleading. Except as set forth in the
financial statements of the Company included in the SEC Documents, the Company
has no material liabilities, contingent or otherwise (to the best of the
knowledge of the Company's Chief Executive Officer, President or any other
senior level officer of the Company (the "Company's Knowledge")), other than (i)
liabilities incurred in the ordinary course of business subsequent to the date
of such financial statements 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, in each case of clause (i) and (ii) next above which, individually
or in the aggregate, are not material to the financial condition, business,
operations, properties, operating results or prospects of the Company. The SEC
Documents contain a complete and accurate list of all written and oral
contracts, agreements, leases or other instruments to which the Company or any
subsidiary is a party or by which the Company or any subsidiary is subject which
are required by the rules and regulations

                                      -8-
<PAGE>   9
promulgated by the SEC to be so listed (each a "Contract"). None of the Company,
its subsidiaries or, to the best of the Company's Knowledge, any of the other
parties thereto, is in breach or violation of any Contract, including without
limitation any default in payment under any of the Company's promissory notes
issued in connection with the Series A Preferred Shares, which breach or
violation would, or with the lapse of time, the giving of notice, or both, have
a Material Adverse Effect.

         i. Absence of Certain Changes. Except as disclosed in the SEC
Documents, since at least May 1, 1999, there has been no material adverse change
and no material adverse development in the business, properties, operation,
financial condition, results of operations or prospects of the Company. The
Company has not taken any steps, and does not currently have any reasonable
expectation of taking any steps, to seek protection pursuant to any bankruptcy
law nor does the Company have any knowledge that its creditors intend to
initiate involuntary bankruptcy proceedings. The Company shall, at least until
Buyer no longer holds any of the Securities, maintain its corporate existence in
good standing and shall pay all taxes when due except for taxes it reasonably
disputes.

         j. Absence of Litigation. Except as set forth in Schedule 3(j)
(attached if applicable), there is no action, suit, proceeding, inquiry or
investigation before or by any court, public board or body pending or, to the
best of the Company's Knowledge, threatened against or affecting the Company,
wherein an unfavorable decision, ruling or finding would reasonably be expected
to have a Material Adverse Effect or which would reasonably be expected to
adversely affect the validity or enforceability of, or the authority or ability
of the Company to perform its obligations under, this Agreement or any of the
documents contemplated herein.

         k. Foreign Corrupt Practices. Neither the Company nor any of its
subsidiaries, nor to the best of the Company's Knowledge, any officer, director
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 expense
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 violation of any provision of the U.S. Foreign Corrupt
Practices Act of 1977, as amended; or made any bribe, rebate, payoff, influence
payment, kickback or other unlawful payment to any foreign or domestic
government official or employee.

         l. Brokers; No General Solicitation. The Company has taken no action
that would give rise to any claim by any person for brokerage commissions,
finder's fees or similar payments relating to this Agreement and the
transactions contemplated hereby, other than to Delano Group Securities, L.L.C.
The Company and the Buyer both acknowledge that no other broker or finder was
involved with respect to the transactions contemplated hereby, other than Delano
Group Securities, L.L.C. Neither the Company nor any distributor participating
on the Company's behalf in the transactions contemplated hereby nor any person
acting for the Company, or any such distributor, has conducted any "general
solicitation," as described in Rule 502(c) under Regulation D, with respect to
the Securities being offered hereby.

                                      -9-
<PAGE>   10
         m. Acknowledgment of Dilution. The number of Conversion Shares (and
Option Shares) issuable upon conversion of the Preferred Stock (and exercise of
the Option) and the number of Warrant Shares issuable upon exercise of the
Warrant may increase substantially in certain circumstances, including the
circumstance wherein the trading price of the Common Stock declines. The
Company's executive officers and directors have studied and fully understand the
nature of the securities being sold hereunder and recognize they have a
potential dilutive effect. The board of directors of the Company has concluded
in its good faith business judgment that such issuance is in the best interests
of the Company. The Company acknowledges that its obligation to issue Conversion
Shares upon conversion of the Preferred Stock (and Option Shares upon exercise
of the Option, if applicable) and Warrant Shares upon exercise of the Warrants
is binding upon it and enforceable regardless of the dilution that such issuance
may have on the ownership interests of other stockholders.

         n. Eligibility to File Registration Statement. The Company is currently
eligible to file a registration statement with the SEC either on Form SB-1 or
Form SB-2 under the 1933 Act.

         o. (Intentionally Omitted.)

         p. Non-Disclosure of Non-Public Information. (a) The Company shall in
no event disclose non-public information to the Buyer, advisors to or
representatives of the Buyer unless prior to such disclosure of information the
Company marks such information as "non-public information - confidential" and
provides the Buyer, such advisors and representatives with the opportunity to
accept or refuse to accept such non-public information for review. The Company
may, as a condition to disclosing any non-public information hereunder, require
the Buyer, its advisors and representatives to enter into a confidentiality
agreement in form reasonably satisfactory to the Company and the Buyer.

            (b) Nothing herein shall require the Company to disclose non-public
information to the Buyer, its advisors or representatives, and the Company
represents that it does not disseminate non-public information to investors who
purchase stock in the Company in a public offering, to money managers or to
securities analysts; provided, however, that notwithstanding anything herein to
the contrary, the Company will, as hereinabove provided, immediately notify the
advisors and representatives of the Buyer and, if any, underwriters, of any
event or the existence of any circumstance (without any obligation to disclose
the specific event or circumstance) of which it becomes aware, constituting
non-public information (whether or not requested of the Company specifically or
generally during the course of due diligence by such persons or entities),
which, if not disclosed in the prospectus included in the registration statement
to be filed pursuant to the Registration Rights Agreement, would cause such
prospectus to include a material misstatement or to omit a material fact
required to be stated therein in order to make the statements therein, in light
of the circumstances in which they were made, not misleading. Nothing herein
shall be construed to mean that such persons or entities other than the Buyer
(without the written consent of the Buyer prior to disclosure of such
information) may not obtain non-public information in the course of conducting
due diligence in accordance with the terms of this Agreement and nothing herein
shall prevent any such persons or entities from notifying the Company of their
opinion that, based upon such due diligence by such persons or entities, that
the registration statement contains an untrue

                                      -10-

statement of a material fact or omits a material fact required to be stated in
such registration statement or necessary to make the statements contained
therein, in light of the circumstances in which they were made, not misleading.

         4. COVENANTS.

         a. Best Efforts. Each party shall use its best efforts timely to
satisfy each of the conditions to be satisfied by it as provided in Sections 6
and 7 of this Agreement.

         b. Securities Laws. The Company agrees to timely file a Form D (and any
equivalent form required by applicable state law) with respect to the Securities
if and as required under Regulation D and applicable state securities laws and
to provide a copy thereof to the Buyer promptly after such filing. The Company
shall, on or before the Closing Date, take such action as is necessary to sell
the Securities being sold to the Buyer on each such date under applicable
securities laws of the United States and the relevant state(s), and shall if
specifically so requested provide evidence of any such action so taken to the
Buyer on or prior to the Closing Date.

         c. Reporting Status. So long as the Buyer beneficially owns any of the
Securities, the Company shall 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 hereunder would permit such termination.

         d. Use of Proceeds. The Company will use the proceeds from the sale of
the Securities for the deployment of the IPVoice Network, and for administrative
overhead and general working capital needs.

         e. Financial Information. Until such time as the Buyer no longer
beneficially owns Securities, the Company agrees to send the following reports
to the Buyer: (i) after filing with the SEC, a copy of each of its Annual
Reports, its Quarterly Reports, and any reports filed on Form 8-K; and (ii) as
soon as reasonably practicable after release thereof, copies of all press
releases issued by the Company or any of its subsidiaries.

         f. 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 the issuance of all of the Conversion
Shares, the Option Shares, the Warrant Shares and the Dividend Shares (if any).
Prior to complete conversion of the Preferred Stock, exercise of the Option and
exercise of the Warrants, the Company shall not reduce the number of shares of
Common Stock reserved for issuance hereunder without the written consent of the
Buyer except for a reduction proportionate to a reverse stock split effected for
a business purpose other than affecting the requirements of this Section, which
reverse stock split affects all shares of Common Stock equally.

         g. Listing. Upon the Closing, the Company shall promptly secure the
listing of the Common Stock underlying the Preferred Stock and the 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 shall maintain, so long as any other shares of Common

                                      -11-
<PAGE>   12
Stock shall be so listed, such listing of shares of Registrable Securities from
time to time issued under the terms of this Agreement and the Registration
Rights Agreement. The Company shall at all times comply in all respects with the
Company's reporting, filing and other obligations under the by-laws or rules of
the National Association of Securities Dealers and the OTC Bulletin Board Market
(or such other national securities exchange or market on which the Common Stock
may then be listed, as applicable).

         h. Prospectus Delivery Requirement; Escrow of Registrable Securities.
The Buyer understands that the 1933 Act requires delivery of a prospectus
relating to the Common Stock in connection with any sale thereof pursuant to a
registration statement under the 1933 Act covering any resale by the Buyer of
the Common Stock being sold, and the Buyer shall comply with any applicable
prospectus delivery requirements of the 1933 Act in connection with any such
sale. The Company shall have the unequivocal right to rely upon the Buyer's
representation and covenant to deliver a prospectus as required by applicable
law or regulation contained in this Section 4(h), and thus, with respect to any
resales by the Buyer pursuant to a registration statement of Common Stock
(including Option Shares) issued to the Buyer upon conversion of the Preferred
Stock (or in payment of dividends on the Preferred Stock), upon exercise of the
Option or upon exercise of the Warrants, such Common Stock shall not contain a
restrictive legend of any kind. The Buyer will indemnify and hold harmless the
Company and its transfer agent for any loss, cost or expense (including
reasonable attorney's fees) incurred by such parties as a result of improper
actions taken by the Buyer in response to the Company's and the transfer agent's
compliance with the provisions of this Section 4(h), including without
limitation the sales of such Common Stock without delivery of a prospectus as
required by applicable law or regulation. The Company agrees that, upon
effectiveness of the Registration Statement, and from time to time thereafter as
reasonably requested by the Buyer, the Company shall deliver or cause the
Company's transfer agent to deliver to the Escrow Agent (as defined in that
Escrow Agreement attached hereto as Exhibit D) one or more stock certificates
representing the number of shares of registered Common Stock into which the
Registrable Securities might then reasonably be convertible or exercisable (as
applicable) (collectively, the "Escrow Shares"). Such certificate(s) shall not
contain a restrictive legend of any kind. The Escrow Agent shall hold the Escrow
Shares in trust, in certificate form or in a brokerage account as deemed
appropriate by the Escrow Agent. Upon a conversion of Preferred Stock (and/or
exercise of the Option), the Buyer shall deliver a copy of its conversion notice
to the Escrow Agent, and to the extent that the Escrow Agent has sufficient
Escrow Shares, the Escrow Agent shall release Escrow Shares to the Buyer to
satisfy such conversion or exercise. The Escrow Agreement describes in detail
the duties of the Escrow Agent with respect to the provisions of this Section
4(h).

         i. Intentional Acts or Omissions. Neither party shall intentionally
perform any act that if performed, or omit to perform any act that if omitted to
be performed, would prevent or excuse the performance of this Agreement or any
of the transactions contemplated hereby.

         j. No Shorting. As a material inducement for the Company to enter into
this Agreement, the Buyer represents that it has not as of the date hereof, and
covenants on behalf of itself and its affiliates that neither Buyer nor any
affiliate of Buyer will at any time in which the Buyer or any affiliate of the
Buyer beneficially owns any of the Securities, engage in any short sales of, or
hedging or arbitrage transactions with respect to, the Common Stock, or buy
"put" options or

                                      -12-
<PAGE>   13
similar instruments with respect to the Common Stock. The Company acknowledges
that a sale of Conversion Shares, Option Shares or Warrant Shares on the date a
conversion of the Preferred Stock (or exercise notice for the Warrants) is made,
even if such sale is made prior to delivery of the notice of conversion with
respect to such Conversion Shares (or exercise notice with respect to such
Warrant Shares), is not a "short sale" for purposes of this Section 4(j).

         k. Expenses. The Company agrees to pay to or at the direction of the
Buyer the sum of $3,000.00 at the Closing as reimbursement for the attorney's
fees and expenses of the Buyer incurred by it in connection with the
transactions contemplated by this Agreement.

         l. No Additional Issuance of Series B Preferred Stock. The Company
agrees that it will not issue Preferred Stock to any person other than to the
Buyer or to the other buyer concurrently executing agreements of like tenor with
this Agreement (the "Other Buyer") in respect of the transactions contemplated
herein and therein.

         m. Restriction on Below Market Issuance of Securities. Until the date
which is the earlier of twelve (12) months from the Closing Date or the date the
Preferred Stock has been redeemed or converted in full, the Company shall not
issue or agree to issue (other than (i) to the Buyer and to the Other Buyer
pursuant to the transactions contemplated herein, (ii) pursuant to any employee
stock option plan or employee stock purchase plan of the Company established
during the term of this restriction for a legitimate business purpose and not to
avoid the restrictions imposed in this Section 4(m), (iii) pursuant to any
existing security, option, warrant, scrip, call or commitment or right in each
case as disclosed on Schedule 3(c) hereof, or (iv) with the consent of the Buyer
and the Other Buyer, not to be unreasonably withheld) any equity securities of
the Company (or any security convertible into or exercisable or exchangeable,
directly or indirectly, for equity securities of the Company) or debt securities
of the Company if such securities are issued at a price (or provide for a
conversion, exercise or exchange price) which may be less than the current
market price for the Common Stock on the date of issuance (in the case of Common
Stock) or the date of conversion, exercise or exchange (in the case of
securities convertible into or exercisable or exchangeable, directly or
indirectly, for Common Stock). In the event the Company seeks to offer such
securities as permitted in subsection 4(m)(iv) of this Section, the Company
shall first offer to the Buyer and to the Other Buyer, pro rata, the opportunity
to purchase such securities on the same terms and conditions as proposed by the
Company (the "First Offer"). The Buyer shall have ten (10) days to advise the
Company in writing that it accepts its pro rata share of the First Offer. If the
Buyer does not so advise the Company, the Company shall be free, for a period of
sixty (60) days, to issue such securities as proposed to such other party, after
which sixty (60) day period the restrictions contained in this Section 4(m)
shall apply as if the Buyer had not given its consent and the First Offer had
not been made to the Buyer. Except as provided with respect to the transactions
contemplated herein (including also the issuance of certain warrants to Delano
Group Securities, L.L.C.) and with respect to the Securities issued and sold to
the Other Buyer, and in subsections (i), (ii), (iii), or (iv) above of this
Section 4(m), until such time as the Preferred Stock has been paid or converted
in full, the Company shall not grant any additional so-called "registration
rights."

         5. LEGEND AND TRANSFER INSTRUCTIONS.

                                      -13-
<PAGE>   14
         a. Transfer Agent Instructions. The Company shall instruct its transfer
agent to issue certificates, registered in the name of the Buyer or its
permitted nominee, for the Conversion Shares, the Option Shares, the Warrant
Shares and the Dividend Shares (if any) in accordance with the terms of the
applicable Preferred Stock and Warrants and in such amounts as are set forth in
the Certificate of Designation and Warrants, respectively, upon conversion of
the Preferred Stock or exercise of the Warrants (as applicable). All such
certificates shall bear the restrictive legend specified in Section 2(g) of this
Agreement only to the extent required by applicable law and as specified in this
Agreement and the Exhibits and Addenda hereto, and with consideration to Section
4(h) hereof. The Company warrants that no instruction other than such
instructions referred to in this Section 5, and stop transfer instructions to
give effect to Section 2(f) hereof in the case of the Conversion Shares, the
Option Shares, the Warrant Shares and the Dividend Shares (if any) prior to the
registration of same under the 1933 Act, will be given by the Company to its
transfer agent and that the Conversion Shares, the Option Shares, the Warrant
Shares and the Dividend Shares (if any) shall otherwise be freely transferable
on the books and records of the Company as and to the extent permitted by
applicable law and provided by this Agreement, the Warrants and the Registration
Rights Agreement. Nothing in this Section shall affect in any way the Buyer's
obligations and agreement to comply with all applicable securities laws upon
resale of the Conversion Shares, the Option Shares, the Warrant Shares and/or
the Dividend Shares (if any). If the Buyer (x) provides the Company with an
opinion of counsel reasonably satisfactory to Company that registration by the
Buyer of the Preferred Stock, the Warrants, the Warrant Shares, the Conversion
Shares, the Option Shares and/or the Dividend Shares (if any) is not required
under the 1933 Act and that resale is otherwise permitted under applicable
securities laws, or (y) transfers Securities to an affiliate which is an
accredited investor (in accordance with the provisions of this Agreement) or in
compliance with Rule 144, then in either instance the Company shall permit the
said transfer, and if applicable promptly (and in all events within two (2)
trading days) instruct its transfer agent to issue one or more certificates in
such name and in such denominations as specified by the Buyer.

         b. Removal of Legends. The Legend shall be removed and the Company
shall issue a certificate without such Legend to the holder of any Security upon
which it is stamped, and a certificate for a security shall be originally issued
without the Legend, if, unless otherwise required by state securities laws, (x)
the sale of such Security is registered under the 1933 Act, or (y) such holder
provides the Company with an opinion by counsel reasonably satisfactory to the
Company, that is in form, substance and scope reasonably satisfactory to the
Company, to the effect that a public sale or transfer of such Security may be
made without registration under the 1933 Act or (z) such holder provides the
Company with assurances reasonably satisfactory to the Company and its counsel,
that such Security can be sold pursuant to Rule 144. The Buyer agrees that its
sale of all Securities, including those represented by a certificate(s) from
which the Legend has been removed, or which were originally issued without the
Legend, shall be made only pursuant to an effective registration statement (and
to deliver a prospectus in connection with such sale) or in compliance with an
exemption from the registration requirements of the 1933 Act. In the event the
Legend is removed from any Security or any Security is issued without the Legend
and thereafter the effectiveness of a registration statement covering the sales
of such Security is suspended or the Company determines that a supplement or
amendment thereto is required by applicable securities laws, then upon
reasonable advance notice to the holder of such Security, the Company shall be
entitled to require that the Legend be placed upon any such Security which
cannot then be sold

                                      -14-
<PAGE>   15
pursuant to an effective registration statement or Rule 144 or with respect to
which the opinion referred to in clause (y) next above has not been rendered,
which Legend shall be removed when such Security may be sold pursuant to an
effective registration statement or Rule 144 (or such holder provides the
opinion with respect thereto described in clause (y) next above.

         c. Conversion of Preferred Stock. The Buyer shall have the right to
convert the Preferred Stock sold hereunder and to exercise the Option by
delivering via facsimile an executed and completed Notice of Conversion (as
defined in the Certificate of Designations) to the Company and delivering within
two (2) business days thereafter the original Notice of Conversion and the
original Preferred Stock certificate being converted (but only at such time as
such original Preferred Stock certificate being converted is converted in full
into Common Stock, unless otherwise specifically requested by the Company) by
express courier to the Company. Each date on which a Notice of Conversion is
faxed to the Company in accordance with the provisions hereof shall be deemed a
"Conversion Date." The Company will transmit the certificates (each a
"Certificate" and collectively the "Certificates") representing the shares of
Common Stock issuable upon conversion of any Preferred Stock, including also any
applicable Option Shares and Dividend Shares (along with a replacement
certificate representing the number of preferred shares not so converted, if
applicable) to the Buyer via express courier, within three (3) business days
after the relevant Conversion Date (with respect to each conversion, the
"Deadline"); however, the preceding clause shall not apply to the extent that
the Escrow Agent is (by virtue of the fact that the Escrow Agent is then in
possession of a sufficient number of shares of Common Stock) able to deliver
Common Stock to satisfy such conversion or exercise in accordance with Section
4(h) above and the applicable provisions of the Escrow Agreement. Time is of the
essence with respect to the requirements of the first clause of the immediately
preceding sentence.

         d. Injunctive Relief for Breach. The Company acknowledges that a breach
of its obligations under Sections 5(a), 5(b) and 5(c) above will cause
irreparable harm to the Buyer by vitiating the intent and purpose of the
transactions contemplated hereby. Accordingly the Company agrees that the remedy
at law for a breach of its obligations under such Sections would be inadequate
and agrees, in the event of a breach or threatened breach by the Company of the
provisions of such Sections, the Buyer shall be entitled, in addition to all
other remedies at law or in equity, to an injunction restraining any breach and
requiring immediate issuance and transfer, without the necessity of showing
economic loss and without any bond or other security being required.

         e. Liquidated Damages for Non-Delivery of Certificates. In addition to
the provisions of Section 5(d) above, the Company understands and agrees that a
delay in the issuance of any of the Certificates beyond the Deadline will result
in substantial economic loss and other damages to the Buyer. As partial
compensation to the Buyer for such loss, the Company agrees to pay liquidated
damages (which the Company acknowledges is not a penalty) to the Buyer for
issuance and delivery of any Certificate after the Deadline, in accordance with
the following schedule (where "No. Business Days Late" is defined as the number
of business days beyond three (3) business days from the date of delivery by the
Buyer to the Company of a facsimile Notice of Conversion (or, if later, from the
date on which all other necessary documentation duly executed and in proper form
required for conversion of Preferred Stock as described in this Agreement,
including the original Notice of Conversion, all in accordance with this
Agreement only if such necessary documentation has not been delivered to the

                                      -15-

the Company of the Notice of Conversion as required in this Agreement)):

</TABLE>

         The Company shall pay the Buyer any liquidated damages incurred as
called for under this Section 5(e) by certified or cashier's check upon the
earlier of (i) issuance of the relevant Certificate(s) to the Buyer or (ii) each
monthly anniversary of the receipt by the Company of the Buyer's Notice of
Conversion. Nothing herein shall limit the Buyer's right to pursue actual
damages for the Company's failure to issue and deliver all Certificates to the
Buyer in accordance with the terms of this Agreement or for breach by the
Company of this Agreement. Notwithstanding anything in this Section 5(e) to the
contrary, the Company shall not be responsible for liquidated damages as
described in this Section 5(e) if a delay past a Deadline in delivery of Common
Stock to the Buyer upon a conversion or exercise is solely due to the action (or
omission to act) of the Escrow Agent (that is, if the Escrow Agent has in its
possession a sufficient number of non-legended Escrow Shares to effect a
conversion of Preferred Stock and/or an exercise of the Option, and there is no
Company-caused delay involved in delivery by the Escrow Agent of the requisite
number of Escrow Shares upon such conversion or exercise).

         6. CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL.

         The obligation of the Company hereunder to sell Preferred Stock and
Warrants at the Closing is subject to the satisfaction, on or before the Closing

If to the Buyer, at the address on the signature page of this Agreement. Each
party shall provide written 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 respective successors and assigns.
Neither the Company nor the Buyer shall assign this Agreement or any rights or
obligations hereunder without the prior written consent of the other (which
consent shall not be unreasonably withheld), and in any event any assignee of
the Buyer shall be an accredited investor (as defined in Regulation D), in the
written opinion of counsel who is reasonably satisfactory to the Company and in
form, substance and scope reasonably satisfactory to the Company.
Notwithstanding the foregoing, if applicable, any of the entities constituting
the Buyer (if greater than one (1) entity) may assign its rights hereunder to
any of its "affiliates," as that term is defined under the 1934 Act, without the
consent of the Company; provided, however, that any such assignment shall not
release such assigning entity from its obligations hereunder unless such
obligations are assumed by such affiliate and the Company has prior to such
assignment and assumption consented in writing to the same; and no such
assignment shall be made unless it is made in accordance with any applicable
securities laws of any applicable jurisdiction. Any request for an assignment
made hereunder by the Buyer shall be accompanied by a legal opinion in form,
substance and scope reasonably satisfactory to the Company, that such assignment
is proper under applicable law. Notwithstanding anything herein to the contrary,
Buyer may pledge the Securities as collateral for a bona fide loan pursuant to a
security agreement with a third party lender, and such pledge shall not be
considered an assignment in violation of this Agreement so long as it is made in
compliance with all applicable law.

         h. No Third Party Beneficiaries. This Agreement is intended for the
benefit of the parties hereto, any other buyer who execute an Agreement of like
tenor with this Agreement, 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. Unless this Agreement is terminated under Section 8(1),
the representations and warranties of the Company and the Buyer contained in
Sections 2 and 3 and the agreements and covenants set forth in Sections 4, 5 and
8 shall survive the Closing of the purchase and sale of Securities purchased and
sold hereby.

         j. Publicity. The Company and the Buyer shall have the right to review
before issuance by the other, any press releases or any other public statements
with respect to the transactions contemplated hereby; provided, however, that
the Company shall be entitled, without prior consultation with or approval of
the Buyer, to make any press release or other public disclosure with respect to
such transactions as is required by applicable law and regulations.

                                      -20-
<PAGE>   21
         k. Further Assurance. 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. Termination. In the event that the Closing shall not have occurred
on or before ten (10) business days from the date hereof, this Agreement shall
terminate at the close of business on such date. Neither party may unilaterally
terminate this Agreement after the Closing for any reason other than a material
breach of this Agreement by the non-breaching party. Such termination shall not
be the sole remedy for a breach of this Agreement by the non-breaching party,
and each party shall retain all of its rights hereunder at law or in equity.
Notwithstanding anything herein to the contrary, a party whose breach of a
covenant or representation and warranty or failure to satisfy a condition
prevented the Closing shall not be entitled to terminate this Agreement.

         m. Remedies. No provision of this Agreement providing for any specific
remedy to a party shall be construed to limit such party to the specific remedy
described, and any other remedy that would otherwise be available to such party
at law or in equity shall be so available. Nothing in this Agreement shall limit
any rights a party may have with any applicable federal or state securities laws
with respect to the transactions contemplated hereby.

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

                                  SCHEDULE 3(c)

     WARRANTS, REGISTRATION RIGHTS, DEBT SECURITIES AND OTHER EQUITY RIGHTS

         See Attached Capitalization Chart attached hereto.

         1. Warrants for common stock with piggyback registration rights in
connection with Units sold in February 1999 offering. If all the warrants were
to be exercised, a total of 862,500 shares of common stock would be issued at an
exercise price of $.9875 per share. As of the date of this Agreement, warrants
for 75,000 shares have been exercised. The Company anticipates that more than
half of these warrants will be surrendered pursuant to the Tender Offer that was
commenced on April 20 and will terminate on May 19. To the extent that warrants
are not surrendered and are exercised, the holders of the common stock received
upon exercise have the right. "at any time that the Company proposes to file a
Company registration statement on Form S-1 or other appropriate registration
form (excluding Form 10SB) under the Act (the "Registration Statement"), for its
own account," to request inclusion of those shares in the registration. The
right is subject to typical exceptions.

         2. Equity to be issued pursuant to Executive Stock Option Plan and 2000
Executive Incentive Plan. Between the two plans, the Company has authorized
issuance of up to 1,300,000 shares of common stock. To date, no options have
been granted under either plan. The Company has currently committed to issue
230,00 options to various employees.

         3. International Investment Partners ("IIP") services agreement
granting a Warrant for 5% of the Company's common stock with antidilution
rights, which are still subject to 3.88% antidilution rights. Warrants issuable
at $1.00 per share. IIP has orally agreed to surrender this Warrant and certain
other claims and rights in exchange for 500,000 shares of the Company's common
stock. A written amendment to the IIP agreement is being prepared to memorialize
this change.

         4. Services Agreement with Netgenie.com, Inc. for 250,000 shares of
common stock and warrants to purchase another 450,000 common shares at $2,50 per
shares, all conditioned upon performance. The Company believes that these rights
expired December 31, 1999 without performance by Netgenie.com.

         5. Investor Communications Group/Corporate Imaging received rights for
100,000 shares in the form of warrants exercisable at $2.00 per share over a
two-year period from the date of issuance with piggyback registration rights.
This agreement has been terminated, but the Warrants may still be outstanding.

         6. In connection with the Share Exchange Agreement with SATLINK 3000,
Inc. d/b/a Independent Network Services ("INS"), in approximately April 1999,
the Company agreed to exchange 250,000 of its redeemable convertible preferred
stock for all of the outstanding capital stock of INS. The redeemable preferred
stock was to be converted on a 1 for 1 basis after one year subject to a
redemption right at $2.00 per share. The Company also entered into an Employment
Agreement with Peter Stazzone, the President of INS, granting him 50,000 shares
of redeemable convertible preferred stock as well as 200,000 shares of common
stock and another 100,000 shares of common stock subject to certain conditions.
The Company voided the agreement but has been sued by the shareholders of INS
and Peter Stazzone. The current outcome is unknown.

         7. Letter Agreement with McGinn Smith for 10,000 shares of common stock
if they provide an introduction to appropriate funding for the Company. They
have not presently earned the shares..

                                      -23-
<PAGE>   24
         8. Promissory Notes in connection with the February 1999 private
offering for Units. A total of 46 notes representing $1,145,400 principal amount
are currently outstanding. The Company anticipates that more than half the notes
will be surrendered in connection with the pending tender offer that commenced
on April 20 and expires on May 19. Any remaining notes, or new notes issued in
substitution for the outstanding notes, will be finally due in the spring of
2002.

         9. Senior Convertible Preferred Stock in connection with the Units sold
in February 1999 offering. Currently 1,150 shares are issued and outstanding.
The Company anticipates that a majority of these shares will be surrendered in
connection with the tender offer that commenced on April 20 and expires on May
19.

         10. The Company has committed to issue 100,000 shares of common stock
to various consultants for services rendered.

                                    CONFLICTS

         The Company failed to attain certain projections and violated certain
representations made to investors in connection with the Units sold in February
1999 offering. The Company views these as technical violations and no action has
been taken by any shareholder.

         In April 1999, the Company entered into a share exchange agreement with
SATLINK 3000, Inc. d/b/a Independent Network Services, a Nevada corporation
formed in April, 1998, ("INS") whereby the Company exchanged 250,000 shares of
its Redeemable Convertible Preferred Stock valued at $500,000 for all of the
outstanding capital stock of INS. Such Redeemable Convertible Preferred stock
contains 1 for 1 conversion rights after one (1) year and is redeemable at $2.00
per share. The President of INS, Peter M. Stazzone, remained with the Company as
the President of the subsidiary. At the time of the exchange Mr. Stazzone became
Secretary, Treasurer and Chief Financial Officer of the Company under an
employment agreement. Also at the time of the exchange, Mr. Stazzone received
50,000 shares of the Redeemable Convertible Preferred Stock of the Company.
Pursuant to the Employment Agreement, Mr. Stazzone received 200,000 shares of
the Company's Restricted Common Stock, a stock bonus of 100,000 shares of the
Restricted Common Stock deemed earned on the date of the Share Exchange
Agreement, but to be delivered on the earlier of (i) the first anniversary date
or (ii) Mr. Stazzone's termination and options to purchase an additional 200,000
shares of the restricted Common Stock of the Company exercisable for a period of
three (3) years at an exercise price of $1.00 per share. It was represented that
INS had acquired certain assets, including the rights to INS' name, from the
Bankruptcy Court in the Chapter 11 filing on behalf of Telsave Corporation
("Telsave"). Mr. Stazzone was the Chief Financial Officer of Telsave at the time
the bankruptcy was filed and the Bankruptcy Court was provided with disclosure
of his involvement with INS prior to the Court's approval of the sale of certain
Telsave assets to INS. In June 1998, Mr. Stazzone was loaned $100,000 by INS
which loan bears no interest and has no stated repayment terms. At the time of
the acquisition of INS, the Company believed that it was acquiring the rights to
the carrier identification code 10-10-460 ("CIC Code"). The purchase price was
based in part upon an appraisal of the value of the CIC Code which is loaded in
approximately 60% of the domestic market. However, during the course of the
audit, it was discovered that clear title may not have passed to INS and
subsequently the Company as the owner of INS. Therefore, the Board resolved
that, in the event clear title had not passed to the Company, it would be in the
best interest of the shareholders to unwind the transaction. The Company sought
a legal opinion on the status of such title and just prior to filing Form 10SB
discovered that there was no clear link between the ownership of the CIC Code
and INS. Therefore the Company voted to unwind the transaction ab initio, to
rescind the issuances made under the acquisition and the employment agreements
and to terminate Mr. Stazzone's employment. Mr. Stazzone and INS have instituted
suit against the Company. For such offering, the Company relied upon Section
4(2) of the Act and Rule 506, Section 14-4-126(f) of the Arizona Code and
Section 90.530(11) of the Nevada Code.

                                   LITIGATION

         In April 1999, the Company entered into a share exchange agreement with
SATLINK 3000, Inc. d/b/a Independent Network Services, a Nevada corporation
formed in April, 1998, ("INS") whereby the Company exchanged 250,000 shares of
its Redeemable Convertible Preferred Stock valued at $500,000 for all of the
outstanding capital stock of INS. Such Redeemable Convertible Preferred stock
contains 1 for 1 conversion rights after one (1) year and is redeemable at $2.00

Secretary, Treasurer and Chief Financial Officer of the Company under an

50,000 shares of the Redeemable Convertible Preferred Stock of the Company.
Pursuant to the Employment Agreement, Mr. Stazzone received 200,000 shares of
the Company's Restricted Common Stock, a stock bonus of 100,000 shares of the
Restricted Common Stock deemed earned on the date of the Share Exchange
Agreement, but to be delivered on the earlier of (i) the first anniversary date
or (ii) Mr. Stazzone's termination and options to purchase an additional 200,000

   CERTIFICATE OF DESIGNATION OF THE RELATIVE RIGHTS AND PREFERENCES OF THE
                                    SERIES B
                           CONVERTIBLE PREFERRED STOCK
                                       OF
                                IPVOICE.COM, INC.

It is certified that:

A. The name of the corporation is IPVoice.Com, Inc., a Nevada corporation
(hereinafter the "Company").

B. The certificate of incorporation of the Company, as amended, authorizes the
issuance of Ten Million (10,000,000) shares of Preferred Stock, $.001 par value
per share, and expressly vests in the Board of Directors of the Company the
authority provided therein to issue all of said shares in one or more series and
by resolution or resolutions to establish the designation and number and to fix
the relative rights and preferences of each series to be issued.

C. The Board of Directors of the Company, pursuant to the authority expressly
vested in it, has adopted the following resolutions creating a class of Series B
Preferred Stock:

      RESOLVED, that a portion of the Ten Million (10,000,000) authorized shares
of Preferred Stock of the Company shall be designated as a separate series
possessing the rights and preferences set forth below:

      1. Designation and Amount. The shares of such series shall have a par
value of $.001 per share and shall be designated as "Series B Preferred Stock"
(the "Series B Preferred Stock") and the number of shares constituting the
Series B Preferred Stock shall be up to 7,500. The Series B Preferred Stock
shall be offered for sale at a purchase price of $1,000 per share (the "Purchase
Price").

      2. Dividends. The holders of the outstanding shares of Series B Preferred
Stock shall be entitled to receive, when, as and if declared by the Board of
Directors, out of funds legally available therefor, dividends at an annual rate
of seven and one half percent of the Purchase Price. Such dividends shall be
deemed to accrue on the Series B Preferred Stock and be cumulative, whether or
not there are profits, surplus or other funds of the Company legally available
for the payment of dividends. All dividends declared upon the Series B Preferred
Stock shall be declared pro rata per share. If there shall not have been a sum
sufficient for the payment therefor set apart, the deficiency shall first be
paid before any dividend or other distribution shall be paid or declared and set
apart with respect to any other class of the Company's capital stock, now or
hereafter outstanding. All accrued cash dividends shall be immediately due and
payable on the date such shares of Series B Preferred Stock are converted into
shares of Common Stock, par value $.001 per share ("Common Stock") in accordance
with Section 5 hereof, or are redeemed in accordance with Section 6 hereof.
Dividends may be paid in cash or additional shares of Common Stock of the
Company, as may be determined, from time to time, in the sole discretion of the
Board of Directors. The Company shall not be required to pay any dividends on
the outstanding shares of the Series B

                                      -1-
<PAGE>   29
Preferred Stock prior to the Conversion Date and/or Redemption Date (as defined
below) for such shares.

            For purposes of this Certificate, unless the context otherwise
requires, "distribution" shall mean the transfer of cash or property without
consideration, whether by way of dividend or otherwise, payable other than in
shares of Common Stock or other equity securities of the Company, or the
purchase or redemption of shares of Common Stock or other equity securities of
the Company (other than redemptions set forth in Section 6 below or repurchases
of Common Stock or other equity securities held by employees or consultants of
the Company upon termination of their employment or services pursuant to
agreements providing for such repurchase) for cash or property payable other
than in shares of Common Stock or other equity securities of the Company.

      3.    Liquidation, Dissolution or Winding Up

            (a) Treatment at Liquidation, Dissolution or Winding Up. In the
event of any liquidation, dissolution or winding up of the Company, whether
voluntary or involuntary, before any distribution may be made with respect to
Common Stock or any other series of capital stock, holders of each share of
Series B Preferred Stock shall be entitled to be paid out of the assets of the
Company available for distribution to holders of the Company's capital stock of
all classes, whether such assets are capital, surplus, or capital earnings, such
amount equal to the Purchase Price plus all accrued cash dividends
(collectively, the "Liquidation Amount").

            (b) If the assets of the Company available for distribution to its
shareholders shall be insufficient to pay the holders of shares of Series B
Preferred Stock the full amount of the Liquidation Amount to which they shall be
entitled, the holders of shares of Series B Preferred Stock shall share ratably
in any distribution of assets according to the amounts which would be payable
with respect to the shares of Series B Preferred Stock held by them upon such
distribution if all amounts payable on or which respect to said shares were paid
in full.

            (c) In the event the holders cannot be located by the Company, funds
necessary for such payment shall be set aside by the Company in trust for the
account of holders of the Series B Preferred Stock so as to be available for
such payments. After payment of the Liquidation Amount shall have been made in
full (including funds held in trust pursuant to the preceding sentence), to the
holders of the Series B Preferred Stock, the holders of the Series B Preferred
Stock shall be entitled to no further participation in the distribution of the
assets of the Company, and the remaining assets of the Company legally available
for distribution to its shareholders shall be distributed among the holders of
other classes of securities of the Company in accordance with their respective
terms.

            (d) The holders of Series B Preferred Stock shall have no priority
or preference with respect to distributions made by the Company in connection
with the repurchase of shares of Common Stock issued to or held by employees,
directors or consultants upon termination of their employment or services
pursuant to agreements providing for the right of said repurchase between the
Company and such persons.

      4. Voting Rights. Except as otherwise required by law, and except as set
forth in Section 8 of this Certificate, the holders of Series B Preferred Stock
shall not be entitled to vote upon any matter relating to the business or
affairs of the Company or for any other purpose.

      5. Conversion Rights for the Series B Preferred Stock; Optional Purchase
of Additional Shares of Common Stock. The holders of Series B Preferred Stock
shall have conversion rights as follows ("Conversion Rights"):

            (a) Right to Convert. No shares of Series B Preferred Stock may be
converted prior to the date (the "First Conversion Date") which is the earlier
of (i) the effective date of the registration statement covering the resale of
the shares of Common Stock issuable upon conversion of the Series B Preferred
Stock, and (ii) the one hundred eightieth day after the closing date (the
"Closing Date") of the issuance of the Series B Preferred Stock.

            (b) Conversion Rate. Each share of Series B Preferred Stock may be
converted into the number of fully-paid and non-assessable shares of Common
Stock of the Company calculated in accordance with the following formula
("Conversion Rate"):

      The number of shares issuable upon conversion of one share of Series B
Preferred Stock shall be determined by dividing the Purchase Price by the
Conversion Price, where:

                  (i) The Purchase Price is defined in Section 1 hereof;
provided that, for purposes of this Section 5(b), in the event that the Company
elects to pay the dividends in additional shares of Common Stock which have been
registered under the Securities Act of 1933, as amended, the dividend amount per
share will be added to the Purchase Price for each such share of Series B
Preferred Stock;

                  (ii) the Conversion Price equals the lesser of (x) one hundred
ten percent (110%) of the lowest of the Closing Bid Prices (defined below) for
the Common Stock for the five (5) trading days prior to the date of issuance of
the Series B Preferred Stock being converted (the "Maximum Price"), or (y)
seventy five percent (75%) (the "Conversion Percentage") of the average of the
three (3) lowest Closing Bid Prices for the Common Stock for the thirty (30)
consecutive trading days immediately preceding the Conversion Date (as herein
defined), as reported on the National Association of Securities Dealers OTC
Bulletin Board Market (or on such other national securities exchange or market
as the Common Stock may trade at such time); notwithstanding anything in this
paragraph to the contrary, if the registration statement covering the resale of
the shares of Common Stock issuable upon conversion of the Series B Preferred
Stock has not been declared effective within 180 days (the "Due Date") after the
date of issuance of the Series B Preferred Stock, then the Conversion Percentage
shall decrease by two percent (2%) for each month (that is, each thirty (30) day
period beginning on the 30th day after the Due Date) or partial month in which
the said registration statement has not been declared, or does not remain,
effective; if such registration statement has not been declared and does not
remain effective on the date which is one (1) year after the date of issuance of
the Series B Preferred Stock, then the Conversion Percentage shall be fifty
percent (50%);

                                      -3-
<PAGE>   31
                  (iii) for purposes hereof, the term "Closing Bid Price" shall
mean for any security as of any date, the last closing bid price for such
security on the OTC: Bulletin Board Market as reported by Bloomberg, L.P., or,
if the OTC: Bulletin Board Market is not the principal trading market for such
security, the last closing bid price of such security on the principal
securities exchange or trading market where such security is listed or traded as
reported by Bloomberg, L.P., or, if no last closing bid or trade price is
reported for such security by Bloomberg, L.P., the closing bid price shall be
determined by reference to the closing bid price as reported on the principal
trading market, and if not so reported shall be determined from the average of
the bid prices of any market makers for such security as reported in the "pink
sheets" published by the National Quotation Bureau, Inc. If the closing bid
price cannot be calculated for such security on such date on any of the
foregoing bases, the closing bid price of such security on such date shall be
the fair market value as mutually agreed by the Company and the holders of
two-thirds of the outstanding shares of Series B Preferred Stock.

            (c) Forced Conversion. In the event the holders of the Series B
Preferred Stock have not exercised the Conversion Rights set forth herein within
two years after the date of issuance of the Series B Preferred Stock (the "Final
Date"), the Series B Preferred Stock shall automatically be converted as if the
holders had exercised their Conversion Rights on the Final Date. In addition, in
the event the Company closes on a public offering of its shares of Common Stock
at a price per share equal to or greater than two times the Maximum Price, then
at the election of the Company given by written notice, each share of Series B
Preferred Stock shall automatically be converted into shares of Common Stock on
the date ("Offering Conversion Date") which is seven business days prior to the
scheduled closing date of such public offering at the applicable Conversion Rate
above and the Offering Conversion Date shall be deemed the Conversion Date with
respect to such shares.

            (d) Capital Reorganization or Reclassification. If the Common Stock
issuable upon the conversion of the Series B Preferred Stock shall be changed
into the same or different number of shares of any class or classes of stock,
whether by capital reorganization, reclassification, stock split, stock
dividend, or similar event, then and in each such event, the holder of each
share of Series B Preferred Stock shall have the right thereafter to convert
such share into the kind and amount of shares of stock and other securities and
property receivable upon such capital reorganization, reclassification or other
change which such holder would have received had its shares of Series B
Preferred Stock been converted immediately prior to such capital reorganization,
reclassification or other change.

            (e) Capital Reorganization, Merger or Sale of Assets. If at any time
or from time to time there shall be a capital reorganization of the Common Stock
(other than a subdivision, combination, reclassification or exchange of shares
provided for in Section 5(d) above), or a merger or consolidation of the Company
with or into another corporation, or the sale of all or substantially all of the
Company's properties, stock and/or assets to any other person or entity (any of
which events is herein referred to as a "Reorganization"), then as a part of
such Reorganization, provision shall be made so that the holders of the Series B
Preferred Stock shall thereafter be entitled to receive upon conversion of the
Series B Preferred Stock, the number of shares of stock or other securities or
property of the Company, or of the successor corporation resulting from such
Reorganization, to which such holder would have been entitled if such holder had
converted its shares of Series B Preferred Stock immediately prior to such
Reorganization. In any such case, appropriate adjustment

                                      -4-
<PAGE>   32
shall be made in the application of the provisions of this Section 5 with
respect to the rights of the holders of the Series B Preferred Stock after the
Reorganization, to the end that the provisions of this Section 5 (including
adjustment of the number of shares issuable upon conversion of the Series B
Preferred Stock) shall be applicable after that event in as nearly equivalent a
manner as may be practicable.

            (f) Certificate as to Adjustments; Notice by Company. Upon the
occurrence of each adjustment or readjustment of the Conversion Price of the
Series B Preferred Stock, the Company, at its expense, shall promptly compute
such adjustment or readjustment in accordance with the terms hereof and prepare
and furnish to each holder of such Series B Preferred Stock a certificate
executed by the president and chief financial officer (or in the absence of a
person designated as the chief financial officer, by the treasurer) setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment are based. The Company shall, upon written
request at any time of any holder of Series B Preferred Stock, furnish or cause
to be furnished to such holder a certificate setting forth (A) the Conversion
Price at the time in effect, and (B) the number of shares of Common Stock and
the amount, if any, of other property which at the time would be received upon
the conversion of a share of Series B Preferred Stock.

            (g) Exercise of Conversion Rights. Holders of Series B Preferred
Stock may exercise their right to convert the Series B Preferred Stock by
telecopying an executed and completed notice to the Company and delivering the
original notice in the form annexed hereto as Exhibit A ("Notice of Conversion")
and the certificate representing the Series B Preferred Stock (once fully
converted, unless specifically requested otherwise by the Company) by express
courier. Each business date on which a Notice of Conversion is telecopied to and
received by the Company in accordance with the provisions hereof shall be deemed
a "Conversion Date." Such holders of Series B Preferred Stock which have sent a
Notice of Conversion to the Company shall, if requested by the Company, deliver
the originally executed Series B Preferred Stock certificates to the Company
within three business days from the Conversion Date. The Company will transmit,
or instruct its transfer agent to transmit, the certificates representing shares
of Common Stock issuable upon conversion of any share of Series B Preferred
Stock (together with the certificates representing the Series B Preferred Stock
not so converted, if the prior certificate was delivered to the Company) to the
holder thereof via express courier, by electronic transfer or otherwise, within
three business days after the Company has received the facsimile Notice of
Conversion. In addition to any other remedies which may be available to the
holders of shares of Series B Preferred Stock, except as otherwise stated in the
Purchase Agreement, in the event that the Company fails to deliver, or has
failed to contact its transfer agent within two business days to deliver, such
shares of Common Stock within such three business day period, the holder will be
entitled to revoke the relevant Notice of Conversion by delivering a notice to
such effect to the Company whereupon the Company and the holder shall each be
restored to their respective positions immediately prior to delivery of such
Notice of Conversion. The Notice of Conversion and Series B Preferred Stock
certificates representing the portion of the Series B Preferred Stock converted
shall be delivered as follows:

                        Attention: Ms. Barbara Will, President

            (h) Optional Purchase of Additional Common Stock. On any Conversion
Date relating to a conversion of Series B Preferred Stock by a holder, the
converting holder shall have the option (the "Option") to purchase one (1)
additional share of Common Stock for each share of Common Stock issuable as a
result of such conversion at an exercise price per share equal to the applicable
Conversion Price (such additional shares of Common Stock referred to herein as
"Option Shares"). The holder shall (i) indicate on the Notice of Conversion in
respect of such Conversion Date that it is exercising its Option with respect to
such conversion and shall specify the number of shares of Common Stock with
respect to which the Option is being so exercised, and (ii) shall pay to the
Company in immediately available funds within two (2) business days after such
Conversion Date, the aggregate purchase price for the Option Shares then being
purchased. Without limitation, the provisions of this Section 5 above shall
apply to any exercise by the holder of its Option.

            (i) Lost or Stolen Certificates. Upon receipt by the Company of
evidence of the loss, theft, destruction or mutilation of any Series B Preferred
Stock certificate(s), and (in the case of loss, theft or destruction) of
indemnity or security reasonably satisfactory to the Company, and upon the
cancellation of the Series B Preferred Stock certificate(s), if mutilated, the
Company shall execute and deliver new certificates for Series B Preferred Stock
of like tenure and date. However, the Company shall not be obligated to reissue
such lost or stolen certificates for shares of Series B Preferred Stock if the
holder contemporaneously requests the Company to convert such Series B Preferred
Stock into Common Stock.

            (j) Fractional Shares. No fractional shares of Common Stock shall be
issued upon conversion of shares of Series B Preferred Stock. In lieu of any
fractional share to which the holder would be entitled for this paragraph, the
number of shares of Common Stock to be received shall be rounded to the nearest
whole share.

            (k) Partial Conversion. In the event some but not all of the shares
of Series B Preferred Stock represented by a certificate or certificates are
converted, the Company may require the holder to surrender the said
certificate(s) to the Company within three (3) business days after such a
conversion; if so, the Company shall execute and deliver to or to the order of
the holder, at the expense of the Company, a new certificate representing the
number of shares of Series B Preferred Stock which were not converted.

            (l) Reservation of Common Stock. The Company shall at all times
reserve and keep available out of its authorized but unissued shares of Common
Stock, solely for the purpose of effecting the conversion of the shares of the
Series B Preferred Stock (including also exercise of the Option), such number of
its shares of Common Stock as shall from time to time be sufficient or as may be
available to effect the conversion of all outstanding shares of the Series B
Preferred Stock,

                                      -6-
<PAGE>   34
including also full exercise of the Option, and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all the then outstanding shares of the Series B Preferred
Stock, including also full exercise of the Option, the Company shall use its
best efforts to take such corporate action as may be necessary to increase its
authorized but unissued shares of Common Stock to such number of shares as shall
be sufficient for such purpose.

      6.    Redemption.

            (a) The Company may redeem any or all of the outstanding shares of
the Series B Preferred Stock on any date (the "Redemption Date") set by the
Board of Directors of the Company for such redemption at any time at the
Redemption Price, as that term is defined below, for each share of Series B
Preferred Stock, to be paid in cash on the Redemption Date, provided, that
(except as hereinafter provided) the Company shall not send a Redemption Notice,
as that term is defined below, to any of the holders of Series B Preferred
Stock, unless it has good and clear funds, for payment of the Redemption Price
for the shares of Series B Preferred Stock it intends to redeem, in a bank
account controlled by the Company, and provided further, however, that in the
event the redemption is to be made simultaneously with the closing of a public
offering of the Company, then the Company may send a Redemption Notice even if
it does not have such good and clear funds, but not earlier than on the day
prior to the date the public offering is priced.

            (b) The Redemption Price shall be an amount equal to 127.5% of the
Purchase Price, plus an amount equal to all accrued but unpaid dividends,
whether or not declared, to but excluding the Redemption Date;

            (c) The Redemption Price shall be payable in cash. If fewer than all
of the outstanding shares of Series B Preferred Stock are to be redeemed, the
redemption shall be pro rata among the holders of the Series B Preferred Stock
based upon the number of shares held by such holders and subject to such other
provisions as may be determined by the Board of Directors of the Company.

            (d) Except as otherwise provided in Section 6(a), not less than five
days prior to the Redemption Date, the Company shall send, by facsimile
transmission and by first class mail, postage prepaid, a notice (the "Redemption
Notice") to each holder of Series B Preferred Stock, which notice shall contain
all instructions and materials necessary to enable such holders to tender Series
B Preferred Stock pursuant to the redemption. Such notice shall (i) state that a
redemption is being effected, (ii) specify the Redemption Date, (iii) state that
holders will be required to surrender the certificate or certificates
representing such shares, properly endorsed, in the manner and at the place
specified in the notice prior to the close of business on the business day prior
to the Redemption Date, (iv) state that holders may convert all or any portion
their shares of Series B Preferred Stock into shares of Common Stock, provided
that the Company receives the Notice of Conversion within twenty-four hours from
the time the Redemption Notice was received by such holder and that all other
shares shall be deemed to have been redeemed by the Company on the Redemption
Date at the Redemption Price plus all accrued but unpaid cash dividends whether
or not declared. The Company may not redeem any portion of the Series B
Preferred Stock that has been converted on or prior to the date of the
Redemption Notice. In the event the Company fails to deliver the Redemption
Price plus accrued and unpaid cash dividends on or before (i) one day after the

                                      -7-
<PAGE>   35
Redemption Date or (ii) in the event the redemption is made simultaneously with
the closing of a public offering of the Company, six days after the closing date
of such public offering, the Redemption Notice shall be null and void and the
Company will relinquish its redemption rights provided by this section.

            (e) On the Redemption Date, unless the Company defaults in the
payment for the shares of Series B Preferred Stock tendered pursuant to the
redemption, dividends will cease to accrue with respect to the shares of Series
B Preferred Stock tendered. All rights of holders of such tendered shares will
terminate, except for the right to receive payment therefor, on the Redemption
Date.
            (f) The Company may, at its option, at any time after the mailing of
the Redemption Notice pursuant to Section 6 (d) above, deposit the aggregate
amount payable upon redemption of the Series B Preferred Stock with a bank or
trust company (the "Depositary") having its principal office in New York, New
York, and having a combined capital and surplus (as shown by its then most
recently published financial statement) of at least $200,000,000, designated by
the Board of Directors of the Company, to be held in trust by the Depositary for
payment to the holders of the shares to be redeemed. Upon such deposit, the
Company shall be released and discharged from any obligation to pay the
Redemption Price of the shares to be redeemed, and the holders of the shares
instead shall have the right to receive from the Depositary only, and not from
the Company, the amount payable upon redemption of the shares on surrender to
the Depositary of the certificates representing the shares. Any money so
deposited with the Depositary that is not claimed after one year from the
Redemption Date shall be repaid to the Company by the Depositary on demand, and
the holder of any of the shares shall thereafter look only to the Company for
any payment to which the holder may be entitled. Any interest which accrues on
money deposited with the Depositary shall belong to the Company and shall be
paid to the Company from time to time by the Depositary.

      7. No Reissuance of Series B Preferred Stock. Any share or shares of
Series B Preferred Stock acquired by the Company by reason of redemption,
purchase, conversion or otherwise shall be canceled, shall return to the status
of authorized but unissued preferred stock of no designated series, and shall
not be reissuable or re-sellable by the Company as Series B Preferred Stock.

      8.    Restrictions and Limitations

            (a) Amendments to Charter. The Company shall not amend its
certificate of incorporation without the approval by the holders of at least a
majority of the then outstanding shares of Series B Preferred Stock if such
amendment would:

                  (i) change the relative seniority rights of the holders of
Series B Preferred Stock as to the payment of dividends in relation to the
holders of any other capital stock of the Company, or create any other class or
series of capital stock entitled to seniority as to the payment of dividends in
relation to the holders of Series B Preferred Stock;

                                      -8-
<PAGE>   36
                  (ii) reduce the amount payable to the holders of Series B
Preferred Stock upon the voluntary or involuntary liquidation, dissolution or
winding up of the Company, or change the relative seniority of the liquidation
preferences of the holders of Series B Preferred Stock to the rights upon
liquidation of the holders of other capital stock of the Company, or change the
dividend rights of the holders of Series B Preferred Stock;

                  (iii) cancel or modify the conversion rights of the holders of
Series B Preferred Stock provided for in Section 5 herein; or

                  (iv) cancel or modify the rights of the holders of the Series
B Preferred Stock provided for in this Section 8.

      9. Notices of Record Date. In the event of:

            (a) any taking by the Company of a record of the holders of any
class of securities for the purpose of determining the holders thereof who are
entitled to receive any dividend or other distribution, or any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, or

            (b) any capital reorganization of the Company, any reclassification
or recapitalization of the capital stock of the Company, any merger of the
Company, or any transfer of all or substantially all of the assets of the
Company to any other corporation, or any other entity or person, or

            (c) any voluntary or involuntary dissolution, liquidation or winding
up of the Company, then and in each such event the Company shall mail or cause
to be mailed to each holder of Series B Preferred Stock a notice specifying (i)
the date on which any such record is to be taken for the purpose of such
dividend, distribution or right and a description of such dividend, distribution
or right, (ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, merger, dissolution, liquidation or winding up is
expected to become effective and (iii) the time, if any, that is to be fixed, as
to when the holders of record of Common Stock (or other securities) shall be
entitled to exchange their shares of Common Stock (or other securities) for
securities or other property deliverable upon such reorganization,
reclassification, recapitalization, transfer, merger, dissolution, liquidation
or winding up. Such notice shall be mailed at least ten days prior to the date
specified in such notice on which such action is to be taken.

      10. Certificate of Incorporation. The statements contained in the
foregoing, creating and designating the said Series B issue of Preferred Stock
and fixing the number, powers, preferences and relative, optional,
participating, and other special rights and the qualifications, limitations and
restrictions shall, upon the effective date of said series, be deemed to be
included in and be a part of the Certificate of Incorporation of the Company
pursuant to the relevant provisions of the General Corporation Law of the State
of Nevada.

      11. Limitation on Number of Conversion Shares. (a) Notwithstanding any
other provision herein, the Company shall not be obligated to issue any shares
of Common Stock upon conversion of the Series B Preferred Stock if the issuance
of such shares of Common Stock

                                      -9-
<PAGE>   37
would exceed that number of shares of Common Stock which the Company may issue
upon conversion of the Series B Preferred Stock (the "Exchange Cap") without
breaching the Company's obligations under the rules and regulations of The
Nasdaq Stock Market, Inc., except that such limitation shall not apply in the
event that the Company (a) obtains the approval of its stockholders as required
by applicable rules of The Nasdaq Stock Market, Inc., for issuances of Common
Stock in excess of such amount or (b) obtains a written opinion from outside
counsel to the Company that such approval is not required, which opinion shall
be reasonably satisfactory to the holders of a majority of the shares of Series
B Preferred Stock then outstanding; provided, however, that notwithstanding
anything herein to the contrary, the Company will issue such number of shares of
Common Stock issuable upon conversion of the Series B Preferred Stock at the
then current Conversion Price up to the Exchange Cap. Until such approval or
written opinion is obtained, no holder of Series B Preferred Stock pursuant to
the Securities Purchase Agreement ("Purchase Agreement") shall be issued, upon
conversion of Series B Preferred Stock, shares of Common Stock in an amount
greater than the product of (i) the Exchange Cap amount multiplied by (ii) a
fraction, the numerator of which is the number of shares of Series B Preferred
Stock issued to such holder pursuant to the Purchase Agreement and the
denominator of which is the aggregate amount of all the shares of Series B
Preferred Stock issued to all holders pursuant to the Purchase Agreement (the
"Cap Allocation Amount"). In the event that any holder of Series B Preferred
Stock shall convert all of such holder's shares of Series B Preferred Stock into
a number of shares of Common Stock which, in the aggregate, is less than such
holder's Cap Allocation Amount, then the difference between such holder's Cap
Allocation Amount and the number of shares of Common Stock actually issued to
such holder shall be allocated to the respective Cap Allocation Amounts of the
remaining holders of Series B Preferred Stock on a pro rata basis in proportion
to the number of shares of Series Preferred Stock then held by each such holder.
The provisions of this paragraph will apply only in the event the Company
becomes listed for trading on the NASDAQ stock market (either Small Cap or
National Market).

            (b) Conversion Restrictions. Notwithstanding anything to the
contrary set forth herein or in the Certificate of Designations, in no event
shall any holder of the Series B Preferred Stock be entitled to convert Series B
Preferred Stock (or exercise the Option to receive Option Shares) in excess of
such portion of the principal of the Series B Preferred Stock that, upon giving
effect to such conversion, would cause the aggregate number of shares of Common
Stock beneficially owned by such converting holder and its affiliates to exceed
4.99% of the outstanding shares of the Common Stock following such conversion.
For purposes of the foregoing proviso, the aggregate number of shares of Common
Stock beneficially owned by the holder and its affiliates shall include the
number of shares of Common Stock issuable upon conversion of the Series B
Preferred Stock with respect to which the determination of such proviso is being
made. Except as set forth in the preceding sentence, for purposes of this
Section, beneficial ownership shall be calculated in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended. The limitations
imposed by this Section on conversion of Series B Preferred Stock shall no
longer apply, and the holder of the Series B Preferred Stock may convert all or
any portion of the Series B Preferred Stock, irrespective of the resulting
beneficial ownership of the Company's Common Stock, should any of the following
events occur: (I) The Company shall either: (i) become insolvent; (ii) admit in
writing its inability to pay its debts generally or as they become due; (iii)
make an assignment for the benefit of creditors or commence proceedings for its
dissolution; or (iv) apply for, or consent to the appointment of, a trustee,
liquidator, or receiver for its or for a substantial part of its property or

                                      -10-
<PAGE>   38
business; or (II) A trustee, liquidator or receiver shall be appointed for the
Company or for a substantial part of its property or business without the
Company's consent and such appointment is not discharged within sixty (60) days
after such appointment; or (III) Any governmental agency or any court of
competent jurisdiction at the instance of any governmental agency shall assume
custody or control of the whole or any substantial portion of the properties or
assets of the Company and shall not be dismissed within sixty (60) days
thereafter; or (IV) Any money judgment, writ or Note of attachment, or similar
process in excess of Five Hundred Thousand United States Dollars (US$500,000.00)
in the aggregate shall be entered or filed against the Company or any of its
properties or assets and shall remain unpaid, unvacated, unbonded or unstayed
for a period of fifteen (15) days or in any event later than five (5) days prior
to the date of any proposed sale thereunder; or (V) Bankruptcy, reorganization,
insolvency or liquidation proceedings or other proceedings for relief under any
bankruptcy law or any law for the relief of debtors shall be instituted by or
against the Company and, if instituted against the Company, shall not be
dismissed within sixty days after such institution or the Company shall by any
action or answer approve of, consent to, or acquiesce in any such proceedings or
admit the material allegations of, or default in answering a petition filed in,
any such proceeding.

      12.   Ranking.

            The Series B Preferred Stock shall, with respect to dividend rights
and rights on liquidation, winding up and dissolution, rank senior to any of the
(i) Common Stock and rank senior to or on parity with any preferred stock issued
after the date hereof and any other class or series of stock of the Company.

OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND UNDER
APPLICABLE STATE SECURITIES LAWS OR IPVOICE.COM, INC. SHALL HAVE RECEIVED AN
OPINION OF ITS COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES

REQUIRED.

                               WARRANT TO PURCHASE

                             SHARES OF COMMON STOCK

                                       OF

                                IPVOICE.COM, INC.

                              Expires May 22, 2005

No.: ___                                             Number of Shares: 125,000
Date of Issuance:   May 22, 2000

      FOR VALUE RECEIVED, subject to the provisions hereinafter set forth, the
undersigned, IPVoice.Com, Inc., a Nevada corporation (together with its
successors and assigns, the "Issuer"), hereby certifies that ___________________
or its registered assigns is entitled to subscribe for and purchase, during the
period specified in this Warrant, up to 125,000 shares (subject to adjustment as
hereinafter provided) of the duly authorized, validly issued, fully paid and
non-assessable Common Stock of the Issuer, at an exercise price per share equal
to the Warrant Price then in effect, subject, however, to the provisions and
upon the terms and conditions hereinafter set forth. Capitalized terms used in
this Warrant and not otherwise defined herein shall have the respective meanings
specified in Section 7 hereof.

      1. Term. The right to subscribe for and purchase shares of Warrant Stock
represented hereby shall commence on the date of issuance of this Warrant and
shall expire at 5:00 p.m., mountain standard time, on May 22, 2005 (such period
being the "Term").

      2.    Method of Exercise Payment: Issuance of New Warrant: Transfer and
Exchange.

      (a) Time of Exercise. The purchase rights represented by this Warrant may
be exercised in whole or in part at any time and from time to time beginning on
the date which is ninety (90) days after the first day of the Term.

                                      -1-
<PAGE>   41
      (b) Method of Exercise. The Holder hereof may exercise this Warrant, in
whole or in part, by the surrender of this Warrant (with the exercise form
attached hereto duly executed) at the principal office of the Issuer, and by the
payment to the Issuer of an amount of consideration therefor equal to the
Warrant Price in effect on the date of such exercise multiplied by the number of
shares of Warrant Stock with respect to which this Warrant is then being
exercised, payable at such Holder's election (i) by certified or official bank
check or (ii) by surrender to the Issuer for cancellation of a portion of this
Warrant representing that number of unissued shares of Warrant Stock which is
equal to the quotient obtained by dividing (A) the product obtained by
multiplying the Warrant Price by the number of shares of Warrant Stock being
purchased upon such exercise by (B) the difference obtained by subtracting the
Warrant Price from the Per Share Market Value as of the date of such exercise,
or (iii) by a combination of the foregoing methods of payment selected by the
Holder of this Warrant. In any case where the consideration payable upon such
exercise is being paid in whole or in part pursuant to the provisions of clause
(ii) of this subsection (b), such exercise shall be accompanied by written
notice from the Holder of this Warrant specifying the manner of payment thereof
and containing a calculation showing the number of shares of Warrant Stock with
respect to which rights are being surrendered thereunder and the net number of
shares to be issued after giving effect to such surrender.

      (c) Issuance of Stock Certificates. In the event of any exercise of the
rights represented by this Warrant in accordance with and subject to the terms
and conditions hereof, (i) certificates for the shares of Warrant Stock so
purchased shall be dated the date of such exercise and delivered to the Holder
hereof within a reasonable time, not exceeding three Trading Days after such
exercise and receipt by the Issuer of the surrendered Warrant, and the Holder
hereof shall be deemed for all purposes to be the Holder of the shares of
Warrant Stock so purchased as of the date of such exercise, and (ii) unless this
Warrant has expired, a new Warrant representing the number of shares of Warrant
Stock, if any, with respect to which this Warrant shall not then have been
exercised (less any amount thereof which shall have been canceled in payment or
partial payment of the Warrant Price as hereinabove provided) shall also be
issued to the Holder hereof at the Issuer's expense within such time.

      (d) Transferability of Warrant. Subject to Section 2(e) and except for
transfers to competitors of the Company or their affiliates, this Warrant may be
transferred by a Purchaser without the consent of the Company; provided, that
the number of Holders which are not affiliates of the initial Holder shall in no
event exceed three (3) without the Issuer's prior written consent. Subject to
the provisions of subsection (e) of this Section 2, this Warrant may be
transferred pursuant to this subsection (d) on the books of the Issuer by the
Holder hereof in person or by duly authorized attorney, upon surrender of this
Warrant at the principal office of the Issuer, properly endorsed (by the Holder
executing an assignment in the form attached hereto) and upon payment of any
necessary transfer tax or other governmental charge imposed upon such transfer.
This Warrant is exchangeable at the principal office of the Issuer for Warrants
for the purchase of the same aggregate number of shares of Warrant Stock, each
new Warrant to represent the right to purchase such number of shares of Warrant
Stock as the Holder hereof shall designate at the time of such exchange. All
Warrants issued on transfers or exchanges shall be dated the Original Issue Date
and shall be identical with this Warrant except as to the number of shares of
Warrant Stock issuable pursuant hereto.

      (e)   Compliance with Securities Laws.

                                      -2-
<PAGE>   42
            (i) The Holder of this Warrant, by acceptance hereof, acknowledges
       that this Warrant or the shares of Warrant Stock to be issued upon
       exercise hereof are being acquired solely for the Holder's own account
       and not as a nominee for any other party, and for investment, and that
       the Holder will not offer, sell or otherwise dispose of this Warrant or
       any shares of Warrant Stock to be issued upon exercise hereof except
       pursuant to an effective registration statement, or an exemption from
       registration, under the Securities Act and any applicable state
       securities laws.

            (ii) Except as provided in paragraph (iii) below, this Warrant and
       all certificates representing shares of Warrant Stock issued upon
       exercise hereof shall be stamped or imprinted with a legend in
       substantially the following form:

                  THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON
            EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
            1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES
            LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF
            UNLESS REGISTERED UNDER THE SECURITIES ACT AND UNDER APPLICABLE
            STATE SECURITIES LAWS OR THE ISSUER SHALL HAVE RECEIVED AN OPINION
            OF ITS COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE
            SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE
            SECURITIES LAWS IS NOT REQUIRED.

            (iii) The restrictions imposed by this subsection (e) upon the
       transfer of this Warrant or the shares of Warrant Stock to be purchased
       upon exercise hereof shall terminate (A) when such securities shall have
       been resold pursuant to being effectively registered under the Securities
       Act, (B) upon the Issuer's receipt of an opinion of counsel, in form and
       substance reasonably satisfactory to the Issuer, addressed to the Issuer
       to the effect that such restrictions are no longer required to ensure
       compliance with the Securities Act and state securities laws or (C) upon
       the Issuer's receipt of other evidence reasonably satisfactory to the
       Issuer that such registration and qualification under state securities
       laws is not required. Whenever such restrictions shall cease and
       terminate as to any such securities, the Holder thereof shall be entitled
       to receive from the Issuer (or its transfer agent and registrar), without
       expense (other than applicable transfer taxes, if any), new Warrants (or,
       in the case of shares of Warrant Stock, new stock certificates) of like
       tenor not bearing the applicable legend required by paragraph (ii) above
       relating to the Securities Act and state securities laws.

      (f) Continuing Rights of Holder. The Issuer will, at the time of or at any
time after each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such Holder shall fail to make any such request, the
failure shall not affect the continuing obligation of the Issuer to afford such
rights to such Holder.

                                      -3-
<PAGE>   43
      3.    Stock Fully Paid: Reservation and Listing of Shares: Covenants.

      (a) Stock Fully Paid. The Issuer represents, warrants, covenants and
agrees that all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise hereunder will, upon issuance, be duly authorized,
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges created by or through Issuer. The Issuer further covenants and agrees
that during the period within which this Warrant may be exercised, the Issuer
will at all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

      (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any Governmental Authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

      (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action,
intentionally avoid or seek to avoid the observance or performance of any of the
terms of this Warrant, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such actions as may be
necessary or appropriate to protect the rights of the Holder hereof against
dilution (to the extent specifically provided herein) or impairment. Without
limiting the generality of the foregoing, the Issuer will (i) not permit the par
value, if any, of its Common Stock to exceed the then effective Warrant Price,
(ii) not amend or modify any provision of the Certificate of Incorporation or
by-laws of the Issuer in any manner that would adversely affect in any way the
powers, preferences or relative participating, optional or other special rights
of the Common Stock or which would materially adversely affect the rights of the
Holders of the Warrants, provided, however, that issuing new series of preferred
stock or additional shares of existing series of preferred stock shall not be
deemed a violation hereof, (iii) take all such action as may be reasonably
necessary in order that the Issuer may validly and legally issue fully paid and
nonassessable shares of Common Stock, free and clear of any liens, claims,
encumbrances and restrictions (other than as provided herein) upon the exercise
of this Warrant, and (iv) use its best efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having
jurisdiction thereof as may be reasonably necessary to enable the Issuer to
perform its obligations under this Warrant.

      (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the

                                      -4-
<PAGE>   44
case of any such loss, theft or destruction, upon receipt of indemnity or
security satisfactory to the Issuer or, in the case of any such mutilation, upon
surrender and cancellation of such Warrant, the Issuer will make and deliver, in
lieu of such lost, stolen, destroyed or mutilated Warrant, a new Warrant of like
tenor and representing the right to purchase the same number of shares of Common
Stock.

      (e) Rights and Obligations under the Registration Rights Agreement. The
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the Registration Rights Agreement dated as of even date herewith between the
Issuer and the Holder listed on the signature page thereof (as amended from time
to time, the "Registration Rights Agreement"). The Issuer shall keep or cause to
be kept a copy of the Registration Rights Agreement, and any amendments thereto,
at its chief executive office and shall furnish, without charge, copies thereof
to the Holder upon request.

      4. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

      (a) Recapitalization, Reorganization, Reclassification, Consolidation,
Merger or Sale. (i) In case the Issuer after the Original Issue Date shall do
any of the following (each, a "Triggering Event"): (a) consolidate with or merge
into any other Person and the Issuer shall not be the continuing or surviving
corporation of such consolidation or merger, or (b) permit any other Person to
consolidate with or merge into the Issuer and the Issuer shall be the continuing
or surviving Person but, in connection with such consolidation or merger, any
Capital Stock of the Issuer shall be changed into or exchanged for Securities of
any other Person or cash or any other property, or (c) transfer all or
substantially all of its properties or assets to any other Person, or (d) effect
a capital reorganization or reclassification of its Capital Stock, then, and in
the case of each such Triggering Event, proper provision shall be made so that,
upon the basis and the terms and in the manner provided in this Warrant, the
Holder of this Warrant shall be entitled (x) upon the exercise hereof at any
time after the consummation of such Triggering Event, to the extent this Warrant
is not exercised prior to such Triggering Event, to receive at the Warrant Price
in effect at the time immediately prior to the consummation of such Triggering
Event in lieu of the Common Stock issuable upon such exercise of this Warrant
prior to such Triggering Event, the Securities, cash and property to which such
Holder would have been entitled upon the consummation of such Triggering Event
if such Holder had exercised the rights represented by this Warrant immediately
prior thereto, subject to adjustments (subsequent to such corporate action) as
nearly equivalent as possible to the adjustments provided for in Section 4
hereof or (y) to sell this Warrant (or, at such Holder's election, a portion
hereof) concurrently with the Triggering Event to the Person continuing after or
surviving such Triggering Event, or to the Issuer (if Issuer is the continuing
or surviving Person) at a sales price equal to the amount of cash, property
and/or Securities to which a holder of the number of shares of Common Stock
which would otherwise have been delivered upon the exercise of this Warrant
would have been entitled upon the effective date or closing of any such
Triggering Event (the "Event Consideration"), less the amount or portion of such
Event Consideration having a fair value equal to the aggregate Warrant Price
applicable to this Warrant or the portion hereof so sold.

      (ii) Notwithstanding anything contained in this Warrant to the contrary,
the Issuer will not effect any Triggering Event unless, prior to the
consummation thereof, each Person (other than

                                      -5-
<PAGE>   45
the Issuer) which may be required to deliver any Securities, cash or property
upon the exercise of this Warrant as provided herein shall assume, by written
instrument delivered to, and reasonably satisfactory to, the Holder of this
Warrant, (A) the obligations of the Issuer under this Warrant (and if the Issuer
shall survive the consummation of such Triggering Event, such assumption shall
be in addition to, and shall not release the Issuer from, any continuing
obligations of the Issuer under this Warrant) and (B) the obligation to deliver
to such Holder such Securities, cash or property as, in accordance with the
foregoing provisions of this subsection (a), such Holder shall be entitled to
receive, and such Person shall have similarly delivered to such Holder an
opinion of counsel for such Person, which counsel shall be reasonably
satisfactory to such Holder, stating that this Warrant shall thereafter continue
in full force and effect and the terms hereof (including, without limitation,
all of the provisions of this subsection (a)) shall be applicable to the
Securities, cash or property which such Person may be required to deliver upon
any exercise of this Warrant or the exercise of any rights pursuant hereto.

      (iii) If with respect to any Triggering Event, the Holder of this Warrant
has exercised its right as provided in clause (y) of subparagraph (i) of this
subsection (a) to sell this Warrant or a portion thereof, the Issuer agrees that
as a condition to the consummation of any such Triggering Event the Issuer shall
secure such right of Holder to sell this Warrant to the Person continuing after
or surviving such Triggering Event and the Issuer shall not effect any such
Triggering Event unless upon or prior to the consummation thereof the amounts of
cash, property and/or Securities required under such clause (y) are delivered to
the Holder of this Warrant. The obligation of the Issuer to secure such right of
the Holder to sell this Warrant shall be subject to such Holder's cooperation
with the Issuer, including, without limitation, the giving of customary
representations and warranties to the purchaser in connection with any such
sale. Prior notice of any Triggering Event shall be given to the Holder of this
Warrant in accordance with Section 11 hereof.

      (b) Subdivision or Combination of Shares. If the Issuer, at any time while
this Warrant is outstanding, shall subdivide or combine any shares of Common
Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of Holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the increase in the total number of shares of Common Stock outstanding as a
result of such subdivision, or (ii) in the case of a combination of shares, the
Warrant Price shall be proportionately increased (as at the effective date of
such combination or, if the Issuer shall take a record of Holders of its Common
Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

      (c) Certain Dividends and Distributions. If the Issuer, at any time while
this Warrant is outstanding, shall:

            (i) Stock Dividends. Pay a dividend in, or make any other
      distribution to its stockholders (without consideration therefor) of,
      shares of Common Stock, the Warrant Price shall be adjusted, as at the
      date the Issuer shall take a record of the Holders of the Issuer's Capital
      Stock for the purpose of receiving such dividend or other distribution (or
      if no such record is taken, as at the date of such payment or other
      distribution), to that price determined by multiplying the Warrant Price
      in effect immediately prior to such record date (or if no

                                      -6-
<PAGE>   46
      such record is taken, then immediately prior to such payment or other
      distribution), by a fraction (1) the numerator of which shall be the total
      number of shares of Common Stock outstanding immediately prior to such
      dividend or distribution, and (2) the denominator of which shall be the
      total number of shares of Common Stock outstanding immediately after such
      dividend or distribution (plus in the event that the Issuer paid cash for
      fractional shares, the number of additional shares which would have been
      outstanding had the Issuer issued fractional shares in connection with
      said dividends); or

            (ii) Other Dividends. Pay a dividend on, or make any distribution of
      its assets upon or with respect to (including, but not limited to, a
      distribution of its property as a dividend in liquidation or partial
      liquidation or by way of return of capital), the Common Stock (other than
      as described in clause (i) of this subsection (c)), or in the event that
      the Company shall offer options or rights to subscribe for shares of
      Common Stock, or issue any Common Stock Equivalents, to all of its holders
      of Common Stock, then on the record date for such payment, distribution or
      offer or, in the absence of a record date, on the date of such payment,
      distribution or offer, the Holder shall receive what the Holder would have
      received had it exercised this Warrant in full immediately prior to the
      record date of such payment, distribution or offer or, in the absence of a
      record date, immediately prior to the date of such payment, distribution
      or offer.

      (d) Issuance of Additional Shares of Common Stock. If the Issuer, at any
time while this Warrant is outstanding, shall issue any Additional Shares of
Common Stock (otherwise than as provided in the foregoing subsections (a)
through (c) of this Section 4), at a price per share less than the Warrant Price
then in effect or less than the Per Share Market Value then in effect or without
consideration, then the Warrant Price upon each such issuance shall be adjusted
to that price (rounded to the nearest cent) determined by multiplying the
Warrant Price then in effect by a fraction:

            (i) the numerator of which shall be equal to the sum of (A) the
      number of shares of Common Stock outstanding immediately prior to the
      issuance of such Additional Shares of Common Stock plus (B) the number of
      shares of Common Stock (rounded to the nearest whole share) which the
      aggregate consideration for the total number of such Additional Shares of
      Common Stock so issued would purchase at a price per share equal to the
      greater of the Per Share Market Value then in effect and the Warrant Price
      then in effect, and

            (ii) the denominator of which shall be equal to the number of shares
      of Common Stock outstanding immediately after the issuance of such
      Additional Shares of Common Stock.

The provisions of this subsection (d) shall not apply under any of the
circumstances for which an adjustment is provided in subsections (a), (b) or (c)
of this Section 4. No adjustment of the Warrant Price shall be made under this
subsection (d) upon the issuance of any Additional Shares of Common Stock which
are issued pursuant to any Common Stock Equivalent if upon the issuance of such
Common Stock Equivalent (x) any adjustment shall have been made pursuant to
subsection (e) of this Section 4 or (y) no adjustment was required pursuant to
subsection (e) of this Section 4. No adjustment of the Warrant Price shall be
made under this subsection (d) in an amount less than $.01 per share, but any
such lesser adjustment shall be carried forward and shall be made at the time
and

                                      -7-
<PAGE>   47
together with the next subsequent adjustment, if any, which together with any
adjustments so carried forward shall amount to $.01 per share or more, provided
that upon any adjustment of the Warrant Price as a result of any dividend or
distribution payable in Common Stock or Convertible Securities or the
reclassification, subdivision or combination of Common Stock into a greater or
smaller number of shares, the foregoing figure of $.01 per share (or such figure
as last adjusted) shall be adjusted (to the nearest one-half cent) in proportion
to the adjustment in the Warrant Price.

      (e) Issuance of Common Stock Equivalents. If the Issuer, at any time while
this Warrant is outstanding, shall issue any Common Stock Equivalent (except
Common Stock Equivalents currently outstanding or issued pursuant to contractual
arrangements in existence as of the date of this Warrant) and the price per
share for which Additional Shares of Common Stock may be issuable thereafter
pursuant to such Common Stock Equivalent shall be less than the Warrant Price
then in effect or less than the Per Share Market Value then in effect, or if,
after any such issuance of Common Stock Equivalents, the price per share for
which Additional Shares of Common Stock may be issuable thereafter is amended or
adjusted, and such price as so amended shall be less than the Warrant Price or
less than the Per Share Market Value in effect at the time of such amendment,
then the Warrant Price upon each such issuance or amendment shall be adjusted as
provided in the first sentence of subsection (d) of this Section 4 on the basis
that (1) the maximum number of Additional Shares of Common Stock issuable
pursuant to all such Common Stock Equivalents shall be deemed to have been
issued (whether or not such Common Stock Equivalents are actually then
exercisable, convertible or exchangeable in whole or in part) as of the earlier
of (A) the date on which the Issuer shall enter into a firm contract for the
issuance of such Common Stock Equivalent, or (B) the date of actual issuance of
such Common Stock Equivalent, and (2) the aggregate consideration for such
maximum number of Additional Shares of Common Stock shall be deemed to be the
minimum consideration received or receivable by the Issuer for the issuance of
such Additional Shares of Common Stock pursuant to such Common Stock Equivalent.
No adjustment of the Warrant Price shall be made under this subsection (e) upon
the issuance of any Convertible Security which is issued pursuant to the
exercise of any warrants or other subscription or purchase rights therefor, if
any adjustment shall previously have been made in the Warrant Price then in
effect upon the issuance of such warrants or other rights pursuant to this
subsection (e). If no adjustment is required under this subsection (e) upon
issuance of any Common Stock Equivalent or once an adjustment is made under this
subsection (e) based upon the Per Share Market Value in effect on the date of
such adjustment, no further adjustment shall be made under this subsection (e)
based solely upon a change in the Per Share Market Value after such date.

      (f) Purchase of Common Stock by the Issuer. If the Issuer at any time
while this Warrant is outstanding shall, directly or indirectly through a
Subsidiary or otherwise, purchase, redeem or otherwise acquire any shares of
Common Stock at a price per share greater than the Per Share Market Value then
in effect, then the Warrant Price upon each such purchase, redemption or
acquisition shall be adjusted to that price determined by multiplying such
Warrant Price by a fraction (i) the numerator of which shall be the number of
shares of Common Stock outstanding immediately prior to such purchase,
redemption or acquisition minus the number of shares of Common Stock which the
aggregate consideration for the total number of such shares of Common Stock so
purchased, redeemed or acquired would purchase at the Per Share Market Value;
and (ii) the denominator of which shall be the number of shares of Common Stock
outstanding immediately after such purchase, redemption or acquisition. For the
purposes of this subsection (f), the date as of which the Per Share Market Value
shall be computed shall be the earlier of (x) the date on which

                                      -8-
<PAGE>   48
the Issuer shall enter into a firm contract for the purchase, redemption or
acquisition of such Common Stock, or (y) the date of actual purchase, redemption
or acquisition of such Common Stock. For the purposes of this subsection (f), a
purchase, redemption or acquisition of a Common Stock Equivalent shall be deemed
to be a purchase of the underlying Common Stock, and the computation herein
required shall be made on the basis of the full exercise, conversion or exchange
of such Common Stock Equivalent on the date as of which such computation is
required hereby to be made, whether or not such Common Stock Equivalent is
actually exercisable, convertible or exchangeable on such date. Notwithstanding
anything in this Section to the contrary, no adjustment shall be made in the
event the Issuer redeems or attempts to redeem Series A Preferred Shares (as
defined in the Purchase Agreement) and the warrants accompanying the Series A
Preferred Shares.

      (g) Other Provisions Applicable to Adjustments Under this Section 4. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4:

            (i) Computation of Consideration. The consideration received by the
      Issuer shall be deemed to be the following: to the extent that any
      Additional Shares of Common Stock or any Common Stock Equivalents shall be
      issued for a cash consideration, the consideration received by the Issuer
      therefor, or if such Additional Shares of Common Stock or Common Stock
      Equivalents are offered by the Issuer for subscription, the subscription
      price, or, if such Additional Shares of Common Stock or Common Stock
      Equivalents are sold to underwriters or dealers for public offering
      without a subscription offering, the public offering price, in any such
      case excluding any amounts paid or receivable for accrued interest or
      accrued dividends and without deduction of any compensation, discounts,
      commissions, or expenses paid or incurred by the Issuer for or in
      connection with the underwriting thereof or otherwise in connection with
      the issue thereof; to the extent that such issuance shall be for a
      consideration other than cash, then, except as herein otherwise expressly
      provided, the fair market value of such consideration at the, time of such
      issuance as determined in good faith by the Board. The consideration for
      any Additional Shares of Common Stock issuable pursuant to any Common
      Stock Equivalents shall be the consideration received by the Issuer for
      issuing such Common Stock Equivalents, plus the additional consideration
      payable to the Issuer upon the exercise, conversion or exchange of such
      Common Stock Equivalents. In case of the issuance at any time of any
      Additional Shares of Common Stock or Common Stock Equivalents in payment
      or satisfaction of any dividend upon any class of Capital Stock of the
      Issuer other than Common Stock, the Issuer shall be deemed to have
      received for such Additional Shares of Common Stock or Common Stock
      Equivalents a consideration equal to the amount of such dividend so paid
      or satisfied. In any case in which the consideration to be received or
      paid shall be other than cash, the Board shall notify the Holder of this
      Warrant of its determination of the fair market value of such
      consideration prior to payment or accepting receipt thereof. If, within
      thirty days after receipt of said notice, the Majority Holders shall
      notify the Board in writing of their objection to such determination, a
      determination of the fair market value of such consideration shall be made
      by an Independent Appraiser selected by the Majority Holders with the
      approval of the Board (which approval shall not be unreasonably withheld),
      whose fees and expenses shall be paid by the Issuer.

            (ii) Readjustment of Warrant Price. Upon the expiration or
      termination of the right to convert, exchange or exercise any Common Stock
      Equivalent the issuance of which

                                      -9-
<PAGE>   49
      effected an adjustment in the Warrant Price, if such Common Stock
      Equivalent shall not have been converted, exercised or exchanged in its
      entirety, the number of shares of Common Stock deemed to be issued and
      outstanding by reason of the fact that they were issuable upon conversion,
      exchange or exercise of any such Common Stock Equivalent shall no longer
      be computed as set forth above, and the Warrant Price shall forthwith be
      readjusted and thereafter be the price which it would have been (but
      reflecting any other adjustments in the Warrant Price made pursuant to the
      provisions of this Section 4 after the issuance of such Common Stock
      Equivalent) had the adjustment of the Warrant Price been made in
      accordance with the issuance or sale of the number of Additional Shares of
      Common Stock actually issued upon conversion, exchange or issuance of such
      Common Stock Equivalent and thereupon only the number of Additional Shares
      of Common Stock actually so issued shall be deemed to have been issued and
      only the consideration actually received by the Issuer (computed as in
      clause (i) of this subsection (g)) shall be deemed to have been received
      by the Issuer.

            (iii) Outstanding Common Stock. The number of shares of Common Stock
      at any time outstanding shall (A) not include any shares thereof then
      directly or indirectly owned or held by or for the account of the Issuer
      or any of its Subsidiaries, and (B) be deemed to include all shares of
      Common Stock then issuable upon conversion, exercise or exchange of any
      then outstanding Common Stock Equivalents or any other evidences of
      Indebtedness, shares of Capital Stock (including, without limitation, the
      Preferred Stock) or other Securities which are or may be at any time
      convertible into or exchangeable for shares of Common Stock or Other
      Common Stock.

      (h) Other Action Affecting Common Stock. In case after the Original Issue
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (g) of this
Section 4, inclusive, and the failure to make any adjustment would not fairly
protect the purchase rights represented by this Warrant in accordance with the
essential intent and principle of this Section 4, then the Warrant Price shall
be adjusted in such manner and at such time as the Board may in good faith
determine to be equitable in the circumstances.

      (i) Adjustment of Warrant Share Number. Upon each adjustment in the
Warrant Price pursuant to any of the foregoing provisions of this Section 4, the
Warrant Share Number shall be adjusted, to the nearest whole share, to the
product obtained by multiplying the Warrant Share Number immediately prior to
such adjustment in the Warrant Price by a fraction, the numerator of which shall
be the Warrant Price immediately before giving effect to such adjustment and the
denominator of which shall be the Warrant Price immediately after giving effect
to such adjustment. If the Issuer shall be in default under any provision
contained in Section 3 of this Warrant so that shares issued at the Warrant
Price adjusted in accordance with this Section 4 would not be validly issued,
the adjustment of the Warrant Share Number provided for in the foregoing
sentence shall nonetheless be made and the Holder of this Warrant shall be
entitled to purchase such greater number of shares at the lowest price at which
such shares may then be validly issued under applicable law. Such exercise shall
not constitute a waiver of any claim arising against the Issuer by reason of its
default under Section 3 of this Warrant.

                                      -10-
<PAGE>   50
      (j) Form of Warrant after Adjustments. The form of this Warrant need not
be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

      5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to one of the national
accounting firms currently known as the "big five" selected by the Holder,
provided that the Issuer shall have ten days after receipt of notice from such
Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty days after submission to it
of such dispute. Such opinion shall be final and binding on the parties hereto.
The fees and expenses of such accounting firm shall be paid by the Issuer.

      6. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with and exercise hereof; rather the number of shares of Warrant
Stock shall be rounded up or down to the nearest whole share.

reorganization, reclassification, consolidation, merger, disposition,
dissolution, liquidation or winding-up, as the case may be, shall take place.
Such notice also shall specify the date as of which the holders of Common Stock
of record shall participate in such dividend, distribution or subscription
rights, or shall be entitled to exchange their certificates for Common Stock for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, disposition, dissolution, liquidation
or winding-up, as the case may be. Such notice shall be given at least ten days
prior to the action in question and not less than ten days prior to the record
date or the date on which the Issuer's transfer books are closed in respect
thereto. The Issuer shall give to the Holder notice of all meetings and actions
by written consent of its stockholders, at the same time in the same manner as
notice of any meetings of stockholders is required to be given to stockholders
who do not waive such notice (or, if such requires no notice, then two Trading
Days written notice thereof describing the matters upon which action is to be

                                      -15-

be distributed to the holders of the Common Stock.

prospectively), by a written instrument or written instruments executed by the
Issuer and the Majority Holders; provided, however, that no such amendment or
waiver shall reduce the Warrant Share Number, increase the Warrant Price,

provision of this Section 9 without the consent of the Holder of this Warrant.

agency. If any such provision is not enforceable as set forth in the preceding
sentence, the unenforceability of such provision shall not affect the other
provisions of this Warrant, but this Warrant shall be construed as if such
unenforceable provision had never been contained herein.

the greater number of Registrable Securities. Notwithstanding anything contained
herein to the contrary, if the actual number of shares of Common Stock issuable
upon conversion of the Preferred Stock and upon exercise of the Warrants and the

Company shall prepare and file with the Commission a Registration Statement
covering all Registrable Securities for an offering to be made on a continuous
basis pursuant to Rule 415. The Registration Statement shall be on Form SB-1,
Form SB-2 or Form S-3 (except if the Company is not then eligible to register
for resale the Registrable Securities on Form SB-1, Form SB-2 or Form S-3, in
which case such registration shall be on another appropriate form in accordance

                                       3
<PAGE>   61
herewith). The Company shall use its reasonable best efforts to cause the
Registration Statement to be declared effective under the Securities Act as
promptly as possible after the filing thereof, but in any event prior to the
Effectiveness Date, and to keep such Registration Statement continuously
effective under the Securities Act until such date as is the earlier of (x) the
date when all Registrable Securities covered by such Registration Statement have
been sold by the Purchaser or (y) the date on which the Registrable Securities
may be sold without any restriction pursuant to Rule 144(k) as determined by the
counsel to the Company pursuant to a written opinion letter, addressed to the
Company's transfer agent to such effect (the "Effectiveness Period"). If an
additional Registration Statement is required to be filed because a majority of
the holders of Preferred Stock reasonably determine that the actual number of
shares of Common Stock into which the Preferred Stock is convertible and the
Warrants and Option are exercisable may exceed the number of shares of Common
Stock initially registered in respect of the Conversion Shares, the Option
Shares, the Dividend Shares and the Warrant Shares based upon the computation on
the Closing Date, the holders shall give the Company written notice of such
fact, and the Company shall have twenty (20) Business Days from the date of its
receipt of such notice to file such additional Registration Statement. The
Company shall use its best efforts to cause such additional Registration
Statement to be declared effective by the Commission as soon as possible, but in
no event later than ninety (90) days after filing.

            (b) Shelf Registration. If the Company is not on the Filing Date
eligible to file a registration statement on Form S-3, then as soon as possible
but no later than thirty (30) days after becoming eligible to file a
registration statement for a secondary or resale offering of the Registrable
Securities on Form S-3, the Company shall prepare and file with the Commission a
post-effective amendment to Form SB-1 or Form SB-2 (or such other applicable
form filed in accordance with Section 2(a) above) on Form S-3 to continue the
registration of all Registrable Securities pursuant to a "shelf" Registration
Statement on Form S-3 covering all Registrable Securities for an offering to be
made on a continuous basis pursuant to Rule 415. Notwithstanding anything to the
contrary contained herein, at no time during the Effectiveness Period shall any
of the Registrable Securities cease being registered.

      3.    Registration Procedures.

            In connection with the Company's registration obligations hereunder,
the Company shall:

            (a) Prepare and file with the Commission on or prior to the Filing
Date, a Registration Statement on Form SB-1 or Form SB-2 (or if the Company is
not then eligible to register for resale the Registrable Securities on Form SB-1
or Form SB-2 such registration shall be on another appropriate form in
accordance herewith) in accordance with the method or methods of distribution
thereof as specified by the Holder (except if otherwise directed by the Holder),
and cause the Registration Statement to become effective and remain effective as
provided herein; provided, however, that not less than five (5) Business Days
prior to the filing of the Registration Statement or any related Prospectus or
any amendment or supplement thereto (including any document that would be
incorporated therein by reference), the Company shall (i) furnish to the Holder
and any Special Counsel, copies of all such documents proposed to be filed,
which documents (other than those incorporated by reference) will be subject to
the review of the Holder and such Special Counsel, and (ii) at the request of
the Holder cause its officers and

                                       4
<PAGE>   62
directors, counsel and independent certified public accountants to respond to
such inquiries as shall be necessary, in the reasonable opinion of counsel to
such Holder, to conduct a reasonable investigation within the meaning of the
Securities Act. The Company shall not file the Registration Statement or any
such Prospectus or any amendments or supplements thereto to which the Holder or
any Special Counsel shall reasonably object in writing within three (3) Business
Days of their receipt thereof.

            (b) (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement as may be
necessary to keep the Registration Statement continuously effective as to the
applicable Registrable Securities for the Effectiveness Period and prepare and
file with the Commission such additional Registration Statements in order to
register for resale under the Securities Act all of the Registrable Securities;
(ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424 (or any similar provisions then in force) promulgated under the
Securities Act; (iii) respond as promptly as possible to any comments received
from the Commission with respect to the Registration Statement or any amendment
thereto and as promptly as possible provide the Holder true and complete copies
of all correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
applicable period in accordance with the intended methods of disposition by the
Holder thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

            (c) Notify the Holder of Registrable Securities to be sold and any
Special Counsel as promptly as possible (and, in the case of (i)(A) below, not
less than five (5) Business Days prior to such filing) and (if requested by any
such Person) confirm such notice in writing no later than one (1) Business Day
following the day (i)(A) when a Prospectus or any Prospectus supplement or
post-effective amendment to the Registration Statement is proposed to be filed;
(B) when the Commission notifies the Company whether there will be a "review" of
such Registration Statement and whenever the Commission comments in writing on
such Registration Statement and (C) with respect to the Registration Statement
or any post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable Securities or the initiation of any Proceedings for that
purpose; (iv) if at any time any of the representations and warranties of the
Company contained in any agreement contemplated hereby ceases to be true and
correct in all material respects; (v) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (vi) of the occurrence of any event that makes any statement made
in the Registration Statement or Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated

                                       5
<PAGE>   63
therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

            (d) Use its best efforts to avoid the issuance of, or, if issued,
obtain the withdrawal of, (i) any order suspending the effectiveness of the
Registration Statement or (ii) any suspension of the qualification (or exemption
from qualification) of any of the Registrable Securities for sale in any
jurisdiction, at the earliest practicable moment.

            (e) If requested by the Holders of a majority in interest of the
Registrable Securities, (i) promptly incorporate in a Prospectus supplement or
post-effective amendment to the Registration Statement such information as the
Company reasonably agrees should be included therein and (ii) make all required
filings of such Prospectus supplement or such post-effective amendment as soon
as reasonably practicable after the Company has received notification of the
matters to be incorporated in such Prospectus supplement or post-effective
amendment.

            (f) Furnish to the Holder and any Special Counsel, without charge,
at least one conformed copy of each Registration Statement and each amendment
thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the
Commission.

            (g) Promptly deliver to the Holder and any Special Counsel, without
charge, as many copies of the Prospectus or Prospectuses (including each form of
prospectus) and each amendment or supplement thereto as such Persons may
reasonably request; and the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders in connection with the offering and sale of the Registrable Securities
covered by such Prospectus and any amendment or supplement thereto.

            (h) Prior to any public offering of Registrable Securities, use its
best efforts to register or qualify or cooperate with the selling Holders and
any Special Counsel in connection with the registration or qualification (or
exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions within the United States as any Holder reasonably requests in
writing, to keep each such registration or qualification (or exemption
therefrom) effective during the Effectiveness Period and to do any and all other
acts or things reasonably necessary or advisable to enable the disposition in
such jurisdictions of the Registrable Securities covered by a Registration
Statement; provided, however, that the Company shall not be required to qualify
generally to do business in any jurisdiction where it is not then so qualified
or to take any action that would subject it to general service of process in any
such jurisdiction where it is not then so subject or subject the Company to any
material tax in any such jurisdiction where it is not then so subject.

            (i)    Cooperate with the Holder to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold pursuant to a Registration Statement, which certificates shall be free
of all restrictive legends, and to enable such Registrable

                                       6
<PAGE>   64
Securities to be in such denominations and registered in such names as any
Holder may request within at least two (2) Business Days after notice thereof.

            (j) Upon the occurrence of any event contemplated by Section
3(c)(vi), as promptly as possible, prepare a supplement or amendment, including
a post-effective amendment, to the Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, and file any other required document so that, as
thereafter delivered, neither the Registration Statement nor such Prospectus
will contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.

            (k) Use its best efforts to cause all Registrable Securities
relating to such Registration Statement to be listed on the OTC Bulletin Board
and any other securities exchange, quotation system, market or over-the-counter
bulletin board, if any, on which similar securities issued by the Company are
then listed as and when required pursuant to the Purchase Agreement.

            (l) Comply in all material respects with all applicable rules and
regulations of the Commission and make generally available to its security
holders earning statements satisfying the provisions of Section 11(a) of the
Securities Act and Rule 158 not later than 45 days after the end of any 12-month
period (or 90 days after the end of any 12-month period if such period is a
fiscal year) commencing on the first day of the first fiscal quarter of the
Company after the effective date of the Registration Statement, which statement
shall conform to the requirements of Rule 158.

            (m) Require each selling Holder to furnish to the Company
information regarding such Holder and the distribution of such Registrable
Securities as is required by law to be disclosed in the Registration Statement,
and the Company may exclude from such registration the Registrable Securities of
any such Holder who fails to furnish such information within a reasonable time
prior to the filing of each Registration Statement, supplemented Prospectus
and/or amended Registration Statement.

            If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any similar federal statute then in
force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

            Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(g) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective as contemplated by
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to them in connection with sales of Registrable Securities pursuant
to the Registration Statement.

                                       7
<PAGE>   65
            Each Holder agrees by its acquisition of such Registrable Securities
that, upon receipt of a notice from the Company of the occurrence of any event
of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v) or
3(c)(vi), such Holder will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until such Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(j), or until it is advised in writing (the "Advice")
by the Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

            (n) If (i) there is material non-public information regarding the
Company which the Company's Board of Directors (the "Board") reasonably
determines not to be in the Company's best interest to disclose and which the
Company is not otherwise required to disclose, or (ii) there is a significant
business opportunity (including, but not limited to, the acquisition or
disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board reasonably determines not to be in the Company's
best interest to disclose and which the Company would be required to disclose
under the Registration Statement, then the Company may postpone or suspend
filing or effectiveness of a registration statement for a period not to exceed
20 consecutive days, provided that the Company may not postpone or suspend its
obligation under this Section 3(n) for more than 45 days in the aggregate during
any 12 month period (each, a "Blackout Period"); provided, however, that no such
postponement or suspension shall be permitted for consecutive 20 day periods,
arising out of the same set of facts, circumstances or transactions.

      4.    Registration Expenses

            All fees and expenses incident to the performance of or compliance
with this Agreement by the Company shall be borne by the Company whether or not
the Registration Statement is filed or becomes effective and whether or not any
Registrable Securities are sold pursuant to the Registration Statement. The fees
and expenses referred to in the foregoing sentence shall include, without
limitation, (i) all registration and filing fees (including, without limitation,
fees and expenses (A) with respect to filings required to be made with the OTC
Bulletin Board and each other securities exchange or market on which Registrable
Securities are required hereunder to be listed, (B) with respect to filings
required to be made with the Commission, (C) with respect to filings required to
be made under the OTC Bulletin Board and (D) in compliance with state securities
or Blue Sky laws (including, without limitation, fees and disbursements of
counsel for the Holder in connection with Blue Sky qualifications of the
Registrable Securities and determination of the eligibility of the Registrable
Securities for investment under the laws of such jurisdictions as the Holders of
a majority of Registrable Securities may designate)), (ii) printing expenses
(including, without limitation, expenses of printing certificates for
Registrable Securities and of printing prospectuses if the printing of
prospectuses is requested by the holders of a majority of the Registrable
Securities included in the Registration Statement), (iii) messenger, telephone
and delivery expenses incurred by the Company, (iv) fees and disbursements of
counsel for the Company and Special Counsel for the Holder, in the case of the
Special Counsel, to a maximum amount of $2,500.00 during the term of this
Agreement, (v) Securities Act liability insurance, if the Company so desires
such

                                       8
<PAGE>   66
insurance, and (vi) fees and expenses of all other Persons retained by the
Company in connection with the consummation of the transactions contemplated by
this Agreement, including, without limitation, the Company's independent public
accountants (including the expenses of any comfort letters or costs associated
with the delivery by independent public accountants of a comfort letter or
comfort letters). In addition, the Company shall be responsible for all of its
internal expenses incurred in connection with the consummation of the
transactions contemplated by this Agreement (including, without limitation, all
salaries and expenses of its officers and employees performing legal or
accounting duties), the expense of any annual audit, the fees and expenses
incurred in connection with the listing of the Registrable Securities on any
securities exchange as required hereunder.

      5.    Indemnification

            (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents, brokers (including brokers who
offer and sell Registrable Securities as principal as a result of a pledge or
any failure to perform under a margin call of Common Stock), investment advisors
and employees of each of them, each Person who controls any such Holder (within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) and the officers, directors, agents and employees of each such controlling
Person, to the fullest extent permitted by applicable law, from and against any
and all losses, claims, damages, liabilities, costs (including, without
limitation, costs of preparation and attorneys' fees) and expenses
(collectively, "Losses"), as incurred, arising out of or relating to any untrue
or alleged untrue statement of a material fact contained in the Registration
Statement, any Prospectus or any form of prospectus or in any amendment or
supplement thereto or in any preliminary prospectus, or arising out of or
relating to any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein (in the case of any
Prospectus or form of prospectus or supplement thereto, in the light of the
circumstances under which they were made) not misleading, except to the extent,
but only to the extent, that such untrue statements or omissions are based
solely or in material part upon information regarding such Holder furnished to
the Company by such Holder, which information was reasonably relied on by the
Company for use therein or to the extent that such information relates to such
Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of
prospectus or in any amendment or supplement thereto. The Company shall notify
the Holder promptly of the institution, threat or assertion of any Proceeding of
which the Company is aware in connection with the transactions contemplated by
this Agreement. Such indemnity shall remain in full force and effect regardless
of any investigation made by or on behalf of an Indemnified Party and shall
survive the transfer of the Registrable Securities by the Holder.

            (b) Indemnification by Holder. The Holders shall, severally and not
jointly, indemnify and hold harmless the Company, the directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses, as
incurred, arising solely or in material part out of or based solely or in
material part

                                       9
<PAGE>   67
upon any untrue statement of a material fact contained in the Registration
Statement, any Prospectus, or any form of prospectus, or arising solely or in
material part out of or based solely or in material part upon any omission of a
material fact required to be stated therein or necessary to make the statements
therein (in the case of any Prospectus or form of prospectus or supplement
thereto, in the light of the circumstances under which they were made) not
misleading, to the extent, but only to the extent, that such untrue statement or
omission is contained in or omitted from any information so furnished by such
Holder to the Company and that such information was reasonably relied upon by
the Company for use in the Registration Statement, such Prospectus or such form
of prospectus or to the extent that such information relates to such Holder or
such Holder's proposed method of distribution of Registrable Securities and was
reviewed and expressly approved in writing by such Holder expressly for use in
the Registration Statement, such Prospectus or such form of prospectus.
Notwithstanding anything to the contrary contained herein, the Holder shall be
liable under this Section 5(b) for only that amount as does not exceed the net
proceeds to such Holder as a result of the sale of Registrable Securities
pursuant to such Registration Statement.

            (c) Conduct of Indemnification Proceedings. If any Proceeding shall
be brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party promptly shall notify the Person
from whom indemnity is sought (the "Indemnifying Party) in writing, and the
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to the Indemnified Party and the payment of all
fees and expenses incurred in connection with defense thereof; provided, that
the failure of any Indemnified Party to give such notice shall not relieve the
Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
except (and only) to the extent that it shall be finally determined by a court
of competent jurisdiction (which determination is not subject to appeal or
further review) that such failure shall have proximately and materially
adversely prejudiced the Indemnifying Party.

            An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an

                                       10
<PAGE>   68
unconditional release of such Indemnified Party from all liability on claims
that are the subject matter of such Proceeding.

            All fees and expenses of the Indemnified Party (including reasonable
fees and expenses to the extent incurred in connection with investigating or
preparing to defend such Proceeding in a manner not inconsistent with this
Section) shall be paid to the Indemnified Party, as incurred, within ten (10)
Business Days of written notice thereof to the Indemnifying Party (regardless of
whether it is ultimately determined that an Indemnified Party is not entitled to
indemnification hereunder; provided, that the Indemnifying Party may require
such Indemnified Party to undertake to reimburse all such fees and expenses to
the extent it is finally judicially determined that such Indemnified Party is
not entitled to indemnification hereunder).

            (d) Contribution. If a claim for indemnification under Section 5(a)
or 5(b) is unavailable to an Indemnified Party because of a failure or refusal
of a governmental authority to enforce such indemnification in accordance with
its terms (by reason of public policy or otherwise), then each Indemnifying
Party, in lieu of indemnifying such Indemnified Party, shall contribute to the
amount paid or payable by such Indemnified Party as a result of such Losses, in
such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party and Indemnified Party in connection with the actions,
statements or omissions that resulted in such Losses as well as any other
relevant equitable considerations. The relative fault of such Indemnifying Party
and Indemnified Party shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of a material fact or omission or alleged omission of a material fact, has been
taken or made by, or relates to information supplied by, such Indemnifying,
Party or Indemnified Party, and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such action, statement or
omission. The amount paid or payable by a party as a result of any Losses shall
be deemed to include, subject to the limitations set forth in Section 5(c), any
reasonable attorneys' or other reasonable fees or expenses incurred by such
party in connection with any Proceeding to the extent such party would have been
indemnified for such fees or expenses if the indemnification provided for in
Sections 5(a) and 5(b) was available to such party in accordance with its terms.
Notwithstanding anything to the contrary contained herein, the Holder shall be
liable or required to contribute under this Section 5(d) for only that amount as
does not exceed the net proceeds to such Holder as a result of the sale of
Registrable Securities pursuant to such Registration Statement.

            The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

            The indemnity and contribution agreements contained in this Section
are in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

      6. Rule 144.

                                       11
<PAGE>   69
            As long as any Holder owns Preferred Stock, Dividend Shares,
Conversion Shares, Option Shares, Warrants or Warrant Shares, the Company
covenants to timely file (or obtain extensions in respect thereof and file
within the applicable grace period) all reports required to be filed by the
Company after the date hereof pursuant to Section 13(a) or 15(d) of the Exchange
Act and to promptly furnish the Holder with true and complete copies of all such
filings. As long as any Holder owns Preferred Stock, Dividend Shares, Conversion
Shares, Option Shares, Warrants or Warrant Shares, if the Company is not
required to file reports pursuant to Section 13(a) or 15(d) of the Exchange Act,
it will prepare and furnish to the Holder and make publicly available in
accordance with Rule 144(c) promulgated under the Securities Act annual and
quarterly financial statements, together with a discussion and analysis of such
financial statements in form and substance substantially similar to those that
would otherwise be required to be included in reports required by Section 13(a)
or 15(d) of the Exchange Act, as well as any other information required thereby,
in the time period that such filings would have been required to have been made
under the Exchange Act. The Company further covenants that it will take such
further action as any Holder may reasonably request, all to the extent required
from time to time to enable such Person to sell Dividend Shares, Conversion
Shares, Option Shares and Warrant Shares without registration under the
Securities Act within the limitation of the exemptions provided by Rule 144
promulgated under the Securities Act, including providing any legal opinions of
counsel to the Company referred to in the Purchase Agreement. Upon the request
of any Holder, the Company shall deliver to such Holder a written certification
of a duly authorized officer as to whether it has complied with such
requirements.

      7.    Miscellaneous.

            (a) Remedies. In the event of a breach by the Company or by a
Holder, of any of their obligations under this Agreement, each Holder or the
Company, as the case may be, in addition to being entitled to exercise all
rights granted by law and under this Agreement, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Company and each Holder agree that monetary damages would not provide adequate
compensation for any losses incurred by reason of a breach by it of any of the
provisions of this Agreement and hereby further agrees that, in the event of any
action for specific performance in respect of such breach, it shall waive the
defense that a remedy at law would be adequate.

            (b) No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has, as of the date hereof entered into and currently in effect,
nor shall the Company or any of its subsidiaries, on or after the date of this
Agreement, enter into any agreement with respect to its securities that is
inconsistent with the rights granted to the Holder in this Agreement or
otherwise conflicts with the provisions hereof except for registration rights
provisions disclosed in the Company's Schedule to the Purchase Agreement. Except
for registration rights provisions disclosed in the Company's Schedule to the
Purchase Agreement, neither the Company nor any of its subsidiaries has
previously entered into any agreement currently in effect granting any
registration rights with respect to any of its securities to any Person. Without
limiting the generality of the foregoing, without the written consent of the
Holders of a majority of the then outstanding Registrable Securities, the
Company shall not grant to any Person the right to request the Company to
register any securities of the Company under the Securities Act unless the
rights so granted are subject in all respects to the prior rights in full of the
Holder set

                                       12
<PAGE>   70
forth herein, and are not otherwise in conflict with the provisions of this
Agreement. This Section 7(b) shall not prohibit the Company from entering into
any agreements concerning the registration of securities on Form S-8 or Form
S-4.

            (c)   [Intentionally Omitted.]

            (d) Piggy-Back Registrations. If at any time when there is not an
effective Registration Statement covering any issued or issuable Conversion
Shares, Option Shares, Dividend Shares or Warrant Shares, and the Company shall
determine to prepare and file with the Commission a registration statement
relating to an offering for its own account or the account of others under the
Securities Act of any of its equity securities, other than on Form S-4 or Form
S-8 (each as promulgated under the Securities Act) or its then equivalents
relating to equity securities to be issued solely in connection with any
acquisition of any entity or business or equity securities issuable in
connection with stock option or other employee benefit plans, the Company shall
send to each holder of Registrable Securities written notice of such
determination and, if within thirty (30) days after receipt of such notice, any
such holder shall so request in writing (which request shall specify the
Registrable Securities intended to be disposed of by the Purchaser), the Company
will cause the registration under the Securities Act of all Registrable
Securities which the Company has been so requested to register by the holder, to
the extent requisite to permit the disposition of the Registrable Securities so
to be registered, provided that if at any time after giving written notice of
its intention to register any securities and prior to the effective date of the
registration statement filed in connection with such registration, the Company
shall determine for any reason not to register or to delay registration of such
securities, the Company may, at its election, give written notice of such
determination to such holder and, thereupon, (i) in the case of a determination
not to register, shall be relieved of its obligation to register any Registrable
Securities in connection with such registration (but not from its obligation to
pay expenses in accordance with Section 4 hereof), and (ii) in the case of a
determination to delay registering, shall be permitted to delay registering any
Registrable Securities being registered pursuant to this Section 7(d) for the
same period as the delay in registering such other securities. The Company shall
include in such registration statement all or any part of such Registrable
Securities such holder requests to be registered; provided, however, that the
Company shall not be required to register any Registrable Securities pursuant to
this Section 7(d) that are eligible for sale pursuant to Rule 144(k) of the
Securities Act. In the case of an underwritten public offering, if the managing
underwriter(s) or underwriter(s) should reasonably object to the inclusion of
the Registrable Securities in such registration statement, then if the Company
after consultation with the managing underwriter should reasonably determine
that the inclusion of such Registrable Securities, would materially adversely
affect the offering contemplated in such registration statement, and based on
such determination recommends inclusion in such registration statement of fewer
or none of the Registrable Securities of the Holder, then (x) the number of
Registrable Securities of the Holders included in such registration statement
shall be reduced pro-rata among such Holders (based upon the number of
Registrable Securities requested to be included in the registration), if the
Company after consultation with the underwriter(s) recommends the inclusion of
fewer Registrable Securities, or (y) none of the Registrable Securities of the
Holder shall be included in such registration statement, if the Company after
consultation with the underwriter(s) recommends the inclusion of none of such
Registrable Securities; provided, however, that if securities are being offered
for the account of other persons or entities as well as the Company, such
reduction shall

                                       13
<PAGE>   71
not represent a greater fraction of the number of Registrable Securities
intended to be offered by the Holder than the fraction of similar reductions
imposed on such other persons or entities (other than the Company).

            (e)   [Intentionally Omitted.]

            (f)   Specific Enforcement, Consent to Jurisdiction.

                  (i) The Company and the Purchaser acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Registration Rights Agreement or the Purchase Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent or cure breaches of the provisions of this Registration
Rights Agreement or the Purchase Agreement and to enforce specifically the terms
and provisions hereof or thereof, this being in addition to any other remedy to
which any of them may be entitled by law or equity.

                  (ii) Each of the Company and the Purchaser (i) hereby
irrevocably submits to the jurisdiction of the United States District Court
sitting in the City of New York, State of New York for the purposes of any suit,
action or proceeding arising out of or relating to this Agreement or the
Purchase Agreement and (ii) hereby waives, and agrees not to assert in any such
suit, action or proceeding, any claim that it is not personally subject to the
jurisdiction of such court, that the suit, action or proceeding is brought in an
inconvenient forum or that the venue of the suit, action or proceeding is
improper. Each of the Company and the Purchaser consents to process being served
in any such suit, action or proceeding by mailing a copy thereof to such party
at the address in effect for notices to it under this Agreement and agrees that
such service shall constitute good and sufficient service of process and notice
thereof. Nothing in this Section 7(f) shall affect or limit any right to serve
process in any other manner permitted by law.

            (g) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and the Holder. Notwithstanding the foregoing, a waiver or consent to depart
from the provisions hereof with respect to a matter that relates exclusively to
the rights of a Holder and that does not directly or indirectly affect the
rights of other Holders may be given by Holders of at least a majority of the
Registrable Securities to which such waiver or consent relates; provided,
however, that the provisions of this sentence may not be amended, modified, or
supplemented except in accordance with the provisions of the immediately
preceding sentence.

            (h) Notices. Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be in writing
and shall be deemed given and effective on the earlier of (i) the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified for notice prior to 5:00 p.m., pacific
standard time, on a Business Day, (ii) the Business Day after the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified for notice later than 5:00 p.m., pacific
standard time, on any date and earlier than 11:59

                                       14
<PAGE>   72
p.m., pacific time, on such date, (iii) the Business Day following the date of
mailing, if sent by nationally recognized overnight courier service or (iv)
actual receipt by the party to whom such notice is required to be given. The
addresses for such communications with respect to each party shall be the
address(es) for such party that are set forth in the Purchase Agreement (as the
same may be modified from time to time by such party in accordance with the
terms of the Purchase Agreement),

or to such other address or addresses or facsimile number or numbers as any such
party may most recently have designated in writing to the other parties hereto
by such notice.

            (i) Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties and their successors and permitted assigns
and shall inure to the benefit of the Holder and its successors and assigns. The
Company may not assign this Agreement or any of its rights or obligations
hereunder without the prior written consent of the Holder. The Purchaser may
assign its rights hereunder in the manner and to the Persons as permitted under
the Purchase Agreement. Notwithstanding anything to the contrary in this
Agreement, no Holder shall assign its rights under this Agreement or otherwise
transfer all or a portion of the Preferred Stock or the Registrable Securities
to any competitor of the Company, and in no event shall there be greater than
three (3) Holders which are not affiliates of the initial Holder during the term
of this Agreement.

            (j) Assignment of Registration Rights. The rights of each Holder
hereunder, including the right to have the Company register for resale
Registrable Securities in accordance with the terms of this Agreement, shall be
automatically assignable by each Holder to any transferee of such Holder of all
or a portion of the Preferred Stock or the Registrable Securities if: (i) the
Holder agrees in writing with the transferee or assignee to assign such rights,
and a copy of such agreement is furnished to the Company within a reasonable
time after such assignment, (ii) the Company is, within a reasonable time after
such transfer or assignment, furnished with written notice of (a) the name and
address of such transferee or assignee, and (b) the securities with respect to
which such registration rights are being transferred or assigned, (iii)
following such transfer or assignment the further disposition of such securities
by the transferee or assignees is restricted under the Securities Act and
applicable state securities laws, (iv) at or before the time the Company
receives the written notice contemplated by clause (ii) of this Section, the
transferee or assignee agrees in writing with the Company to be bound by all of
the provisions of this Agreement, and (v) such transfer shall have been made in
accordance with the applicable requirements of the Purchase Agreement. In
addition, each Holder shall have the right to assign its rights hereunder to any
other Person with the prior written consent of the Company, which consent shall
not be unreasonably withheld. The rights to assignment shall apply to the
Holders (and to subsequent) successors and assigns.

            (k) Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original
and, all of which taken together shall constitute one and the same Agreement. In
the event that any signature is delivered by facsimile transmission, such
signature shall create a valid binding obligation of the party executing (or on
whose behalf such signature is executed) the same with the same force and effect
as if such facsimile signature were the original thereof.

                                       15
<PAGE>   73
            (l) Governing Law. This Agreement shall be governed by and construed
in accordance with the laws of the State of Delaware, without regard to
principles of conflicts of law thereof.

            (m) Cumulative Remedies. The remedies provided herein are cumulative
and not exclusive of any remedies provided by law.

            (n) Severability. If any term, provision, covenant or restriction of
this Agreement is held to be invalid, illegal, void or unenforceable in any
respect, the remainder of the terms, provisions, covenants and restrictions set

affected, impaired or invalidated, and the parties hereto shall use their
reasonable efforts to find and employ an alternative means to achieve the same
or substantially the same result as that contemplated by such term, provision,
covenant or restriction. It is hereby stipulated and declared to be the
intention of the parties that they would have executed the remaining terms,
provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable.

            (o) Headings. The headings herein are for convenience only, do not

Securities is required hereunder, Registrable Securities held by the Company or
its Affiliates (other than any Holder or transferees or successors or assigns
thereof if such Holder is deemed to be an Affiliate solely by reason of its
holdings of such Registrable Securities) shall not be counted in determining
whether such consent or approval was given by the Holders of such required
percentage and shall not be counted as outstanding.

Registration Statement which includes the Registrable Securities is ordered

counsel for the Company to deliver, to the transfer agent for such Registrable
Securities and to the Purchaser (with copies to the Holders whose Registrable
Securities are included in such Registration Statement, if other than the
Purchaser) confirmation that the Registration Statement has been declared
effective by the Commission in the form attached hereto as Exhibit A.

      IN WITNESS WHEREOF, the parties hereto have caused this Registration
Rights Agreement to be duly executed by their respective authorized persons as
of the date first indicated above.

            Re:   IPVOICE.COM, INC.

Ladies and Gentlemen:

      We are counsel to IPVoice.Com, Inc., a Nevada corporation (the "Company"),
and have represented the Company in connection with that certain Securities
Purchase Agreement (the "PURCHASE AGREEMENT"), dated as of May 5, 2000, by and
among the Company and the Purchaser named therein (the "HOLDER") pursuant to
which the Company issued to the Holder its Series B Seven and One Half Percent
(7.5%) Convertible Preferred Stock (the "PREFERRED STOCK") along with warrants
(the "WARRANTS") to purchase shares of the Company's common stock, $.001 par
value per share (the "COMMON STOCK"). Pursuant to the Purchase Agreement, the
Company has also entered into a Registration Rights Agreement with the Holder
(the "REGISTRATION RIGHTS AGREEMENT"), dated of even date with the Purchase
Agreement, pursuant to which the Company agreed, among other things, to register
the Registrable Securities (as defined in the Registration Rights Agreement),
including the shares of Common Stock issuable upon conversion of the Preferred
Stock and exercise of the Warrants, under the Securities Act of 1933, as amended
(the "1933 ACT"). In connection with the Company's obligations under the
Registration Rights Agreement, on             , 2000, the Company filed a
Registration Statement on Form ___ (File No. 333-     ) (the "REGISTRATION
STATEMENT") with the Securities and Exchange Commission (the "SEC") relating to
the resale of the Registrable Securities which names the Holder as a selling
stockholder thereunder.

      In connection with the foregoing, we advise you that a member of the SEC's
staff has advised us by telephone that the SEC has entered an order declaring
the Registration Statement effective under the 1933 Act at [ENTER TIME OF
EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after
telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

                                          Very truly yours,
                                          [COMPANY COUNSEL]

                                       18
<PAGE>   76
                                    EXHIBIT D

                                ESCROW AGREEMENT

      THIS ESCROW AGREEMENT (this "Agreement") is dated as of May 5, 2000, among
IPVoice.Com, Inc., a corporation organized under the laws of the State of
Nevada, U.S.A. (the "Company"), the buyer set forth on the execution page hereof
(the "Buyer") and H. GLENN BAGWELL, JR., a duly licensed attorney who practices
law in the State of North Carolina, U.S.A., as Escrow Agent (the "Escrow
Agent").

      Capitalized terms used herein and not otherwise defined herein shall have
the meanings set forth in that Securities Purchase Agreement between the Company
and the Buyer dated of even date herewith (the "Securities Purchase Agreement").

                             W I T N E S S E T H:

      WHEREAS, the Buyer and the Company have entered into the Securities
Purchase Agreement, pursuant to which the Company has agreed to sell, and the
Buyer has agreed to purchase, at the Closing, a number of shares of Preferred
Stock along with a number of Warrants (collectively, the "Securities"); and

      WHEREAS, the Buyer and the Company have agreed to effectuate the Closing
utilizing an escrow arrangement as described in this Agreement; and

      WHEREAS, it is a condition of the Company's obligation to sell, and the
Buyer's obligation to purchase, the Securities, that this Agreement be executed
and delivered; and

      WHEREAS, the Escrow Agent is willing to act hereunder on the terms and
conditions set forth herein;

      NOW, THEREFORE, in consideration of the mutual covenants and obligations
set forth below, the parties hereto hereby agree as follows:

      1.  Intentionally Omitted.

      1.1 Intentionally Omitted.

      2.  ESCROW OF COMMON STOCK OF THE COMPANY.

          2.1   Intentionally Omitted.

      2.2. Escrow of Common Stock. In accordance with Section 4(h) of the
Securities Purchase Agreement, and based upon certain representations and
warranties contained in the Securities Purchase Agreement, upon registration of
the Registrable Securities, and from time to time as requested by the Buyer
thereafter, the Company shall place in trust with the Escrow Agent one or more
stock certificates representing a number of non-legended shares of Common
<PAGE>   77
Stock as specified in the Securities Purchase Agreement ("Escrow Shares"). The
Escrow Agent shall hold the Escrow Shares in certificate form or in a brokerage
account as the Escrow Agent deems appropriate to fulfill his duties under the
Securities Purchase Agreement and hereunder. None of the Escrow Shares shall be
disbursed other than in accordance with the terms of Section 4(h) of the
Securities Purchase Agreement and of the terms hereof, or in accordance with the
written instructions of both the Company and the Buyer delivered to the Escrow
Agent. In no event shall the Escrow Agent release or transfer any Escrow Shares
to any party other than to the Buyer (or another buyer) or to the Company in
accordance with this Agreement, absent express written instructions from the
Company and the Buyer to transfer Escrow Shares to a third party.

      Upon a full or partial conversion of Preferred Stock or exercise of the
Option, the Buyer shall deliver via facsimile to the Escrow Agent a copy of the
Notice of Conversion (and along with it, if applicable, the Option exercise
form). Likewise, should the Buyer exercise the Warrant in full or in part, the
Buyer shall deliver to the Escrow Agent a copy of such exercise form. The Escrow
Agent shall use its reasonable best efforts to cause the delivery from escrow to
the Buyer (in accordance with the Buyer's written instructions to the Escrow
Agent, and via electronic transfer or otherwise) of the number of shares of
Common Stock specified in the Notice of Conversion (and Option exercise notice,
if applicable) or the Warrant exercise form within three (3) business days after
receipt of such Notice of Conversion (and Option exercise notice) or Warrant
exercise form. The Escrow Agent shall not be responsible for any breach by the
Company of its obligation to timely deliver sufficient Escrow Shares to effect a
conversion or exercise.

      Upon Buyer's receipt of all Common Stock due upon conversion of all of the
Preferred Stock issued to the Buyer, including also any Option Shares to be
issued upon exercise of the Option, or upon exercise of the Warrant, the Buyer
shall inform the Escrow Agent in writing that the requirements of the Securities
Purchase Agreement with respect to the Preferred Stock have been satisfied. The
Company shall instruct the Escrow Agent in writing as to the return to the
Company of the remaining Escrow Shares, and the Escrow Agent shall as soon as
practicable return such remaining Escrow Shares in accordance with the Company's
instructions. Thereafter the Escrow Agent shall have no further obligation to
any party with respect to the Escrow Shares, whether those delivered to the
Buyer or those returned to the Company.

      2.3 Controversies. If any controversy arises between two or more of the
parties hereto, or between any of the parties hereto and any person not a party
hereto, as to whether or not or to whom the Escrow Agent shall deliver the
Escrow or any portion thereof or as to any other matter arising out of or
relating to this Escrow Agreement, the Escrow Agent shall not be required to
determine the same and need not make any delivery of the Escrow concerned or any
portion thereof but may retain the same until the rights of the parties to the
dispute shall have been finally determined by agreement or by final judgment of
a court of competent jurisdiction after all appeals have been finally determined
(or the time for further appeals has expired without an appeal having been
made). The Escrow Agent shall deliver that portion of the Escrow concerned
covered by such agreement or final order within five (5) days after the Escrow
Agent receives a copy thereof. The Escrow Agent shall assume that no such
controversy has arisen unless and until it receives written notice from the
Buyer or the Company
<PAGE>   78
that such controversy has arisen, which refers specifically to this Agreement
and identifies the adverse claimants to the controversy.

      2.4 No Other Disbursements. No portion of the Escrow, whether cash,
securities (including Escrow Shares) or documentation shall be disbursed or
otherwise delivered or transferred except in accordance with this Section 2,
Section 4 or Section 5.1(b), in accordance with the written instructions of both
the Company and the Buyer, or as required by applicable law. Without limiting
the foregoing, neither Escrow Agent nor the Buyer shall be entitled to any right
of offset against the Escrow or otherwise entitled to receive any portion of the
Escrow.

      3. ESCROW AGENT. The acceptance by the Escrow Agent of his duties
hereunder is subject to the following terms and conditions, which the parties to
this Agreement hereby agree shall govern and control with respect to the rights,
duties, liabilities and immunities of the Escrow Agent:

      3.1 The Escrow Agent shall not be responsible or liable in any manner
whatever for the sufficiency, correctness, genuineness or validity of any cash,
investments or other amounts deposited with or held by the Escrow Agent.

      3.2 The Escrow Agent shall be protected in acting upon any written notice,
certificate, instruction, request or other paper or document believed by the
Escrow Agent to be genuine and to have been signed or presented by the proper
party or parties.

      3.3 The Escrow Agent shall not be liable for any act done hereunder except
in the case of the Escrow Agent's willful misconduct or bad faith.

      3.4 The Escrow Agent shall not be obligated or permitted to investigate
the correctness or accuracy of any document or to determine whether or not the
signatures contained in said documents are genuine or to require documentation
or evidence substantiating any such document or signature.

      3.5 The Escrow Agent shall have no duties as Escrow Agent except those
that are expressly set forth herein, and in any modification or amendment
hereof; provided, however, that no such modification or amendment hereof shall
affect his duties unless it shall have given his written consent thereto. The
Escrow Agent shall not be prohibited from owning an equity interest in the
Company, the Buyer, another buyer, any of their respective subsidiaries or any
third party that is in any way affiliated with or conducts business with either
the Company, the Buyer or another buyer.

      3.6 The Company and the Buyer specifically acknowledge that the Escrow
Agent is a practicing attorney in Raleigh, North Carolina U.S.A., and may have
worked with or be affiliated with the Company, the Buyer, or affiliates of
either of them on other transactions, and that they and each of them has
specifically requested that the Escrow Agent draft the documents for the said
transactions and act as Escrow Agent with respect to the said transactions. Each
party represents that it has retained legal and other counsel of its choosing
with respect to the transactions contemplated herein and in the Securities
Purchase Agreement, and is satisfied in its sole

                                       3
<PAGE>   79
discretion with the form and content of the documentation drafted by the Escrow
Agent, as the same has been approved prior to closing by the parties and their
respective counsel. The Escrow Agent may own an equity interest in the Company
and/or may be an equity owner of the Buyer or another buyer, and may increase or
sell any such interest, so long as in accordance with any and all applicable
law. The said parties hereby waive any objection to the Escrow Agent so acting
based upon conflict of interest or lack of impartiality. The Escrow Agent agrees
to act impartially and in accordance with the terms of this Agreement and with
the parties' respective instructions, so long as they are not in conflict with
the terms of this Agreement.

      4. TERMINATION. This Agreement shall terminate on the earlier of (a) the
date on which the Escrow and all other escrowed documents and things described
herein shall have been fully disbursed in accordance with the terms and
conditions of this Agreement, (b) any other date agreed to by the Buyer and the
Company, or (c) the next business day after the expiration of the last of the
Warrants to be issued by the Company in accordance with the terms of the
Securities Purchase Agreement.

      5.    MISCELLANEOUS.

      5.1   Indemnification of Escrow Agent.

      (a) The Company and the Buyer each agree, jointly and severally, to
indemnify the Escrow Agent for, and to hold him harmless against, any loss
incurred without willful misconduct or bad faith on the Escrow Agent's part,
arising out of or in connection with the administration of this Agreement,
including the costs and expenses of defending himself against any claim or
liability in connection with the exercise or performance of any of his powers or
duties hereunder. This indemnification shall not apply to a party with respect
to a direct claim against the Escrow Agent by such party alleging in good faith
a breach of this Agreement by the Escrow Agent, which claim results in a final
non-appealable judgment against the Escrow Agent with respect to such claim.

      (b) In the event of any dispute as to the nature of the rights or
obligations of the Buyer, the Company or the Escrow Agent hereunder, the Escrow
Agent may at any time or from time to time interplead, deposit and/or pay all or
any part of the Escrow Funds with or to a court of competent jurisdiction
sitting in Wake County, North Carolina or in any appropriate federal court, in
accordance with the procedural rules thereof. The Escrow Agent shall give notice
of such action to the Company and the Buyer. Upon such interpleader, deposit or
payment, the Escrow Agent shall immediately and automatically be relieved and
discharged from all further obligations and responsibilities hereunder,
including the decision to interplead, deposit or pay such funds.

      5.2 Amendments. This Agreement may be modified or amended only by a
written instrument executed by each of the parties hereto.

      5.3 Notices. All communications required or permitted to be given under
this Agreement to any party hereto shall be sent by first class mail or
facsimile to such party at the address, except in the case of the Escrow Agent,
of such party set forth in the Securities Purchase

      5.5 Successors and Assigns. This Agreement shall bind and inure to the
benefit of the parties hereto and their respective successors and assigns;
provided, however, that the Escrow Agent shall not assign his duties under this
Agreement.

      5.6 Governing Law. This Agreement shall be governed by and construed and
interpreted in accordance with the laws of the State of North Carolina.

      5.7 Counterparts. This Agreement may be executed in two or more

      Re:   IPVoice.Com, Inc.

Gentlemen:

            We have acted as counsel to IPVoice.Com, Inc., a Nevada corporation
(the "Company"), in connection with your purchase of Series B Convertible
Preferred Stock (the "Preferred Stock"), along with certain warrants (the
"Warrants"), in accordance with the terms of that Securities Purchase Agreement
dated as of May ___, 2000 (the "Agreement") between the Company and
________________ (the "Investor"), (ii) the Registration Rights Agreement dated
as of the date hereof (the "Registration Rights Agreement") between the Company
and the Investor, and (iii) the Escrow Agreement dated as of the date hereof
(the "Escrow Agreement") among the Company, the Investor and H. Glenn Bagwell,
Jr., Esq., as escrow agent. Capitalized terms used herein but not otherwise
defined herein shall have the meanings set forth in the Agreement.

            In connection with rendering this opinion, we have examined the
Agreement, the Registration Rights Agreement, the Escrow Agreement, the
Certificate of Designations as filed (or as it will be filed prior to the
Closing) and the form of the Warrants (collectively, the "Transaction
Documents"), as well as the Company's Articles of Incorporation, as amended
("Articles"), and Bylaws and the resolutions of the Board of Directors of the
Company approving the transactions contemplated by the Transaction Documents.
<PAGE>   83
            We have also made such examination of law and have examined
originals or copies, certified or otherwise, of such corporate records and
documents of the Company, such agreements, certificates of officers or
representatives of the Company, and such other records, certificates, including
certificates of public officials, and documents as we have deemed relevant and
necessary as a basis for the opinions hereinafter expressed. In such
examination, we have assumed the genuineness of all signatures, the authenticity
of all documents submitted to us as originals and the conformity with authentic
original documents of all documents submitted to us as copies. As to any facts
relevant to the opinions expressed below, we have relied upon certificates and
written and/or oral representations of officers of the Company (including the
representations of the Company set forth in the Transaction Documents) and
public officials. We have also assumed that the representations and warranties
of the Investor as set forth in the Transaction Documents are true and correct
as of the date hereof. All references herein to contracts, instruments or other
documents of the Company are limited to such documents as have been provided to
us by the Company or of which we have actual knowledge after due inquiry of the
Company and its officers. As to our opinion in paragraphs 2, 3, and 7 set forth
below, we have examined only resolutions of the Board of Directors of the
Company relating to such share issuances and our opinion set forth in such
paragraphs is limited thereto. We have not examined or reviewed any
communication, instrument, agreement, document or other item or conducted any
independent inquiry or investigation of any matter except as otherwise expressly
set forth above. We have also assumed that the Agreement and the other
Transaction Documents have been executed and delivered by and are binding on
each of the parties thereto.

            The opinions expressed below with respect to compliance with certain
statutes, rules and regulations are based upon a review of those statutes, rules
and regulations that, in our experience, are applicable to transactions of the
type contemplated by the Agreement and to businesses such as the Company's. Our
opinion as to the good standing of the Company in Nevada set forth in the first
sentence of paragraph 1 below is based solely upon our examination of a
certificate of good standing dated April__, 2000 provided by the Secretary of
State of Nevada, and such opinion is given solely as of such date.

            In connection with our opinion with respect to pending litigation
and existing orders, contracts, injunctions, judgements and decrees set forth in
paragraph 5 below we have not undertaken searches of the dockets of any court of
any jurisdiction, nor conducted a judgment, lien, litigation or similar search
and have relied upon certificates and written or oral representations of
officers of the Company.

            We express no opinion respecting the enforceable nature of the
Agreement, the other Transaction Documents, or any document or instrument
executed pursuant thereto or in connection therewith, insofar as the enforceable
nature thereof, or any right, power, privilege, remedy or interest intended to
be created thereunder, may be limited (i) by applicable bankruptcy, insolvency,
moratorium, fraudulent conveyance, reorganization or other laws or judicial
decisions affecting any rights, powers, privileges, remedies or interests of
creditors generally, (ii) by rules or principles of equity affecting the
<PAGE>   84
enforcement of obligations generally, whether at law, in equity or otherwise,
(iii) by the exercise of the discretionary powers of any court or other
authority before which may be brought any proceeding seeking equitable or other
remedies, including, without limitation, specific performance, injunctive relief
and indemnification or (iv) insofar as rights to indemnity and/or contribution
are concerned, by federal or state securities laws or the public policy
underlying such laws.

            Our opinion is limited to the date hereof and we do not in any event
undertake to advise you of any facts or circumstances occurring or coming to our
attention subsequent to the date hereof.

            Where reference is made in this opinion to matters within or to our
knowledge, to the best of our knowledge, or to facts or circumstances known to
us or which have come to our attention, such reference means the actual
knowledge of those attorneys in our firm who have given substantive attention to
the preparation of the Agreement and other Transaction Documents and those
attorneys in our firm who, from time to time, have given substantive attention
to the general corporate and securities matters for which our firm has been
engaged by the Company, their review of documents in connection with this
engagement and the general corporate and securities matters for which our firm
has been engaged by the Company, and inquiries of officers of the Company,
without, however, independent investigation of any matter unless expressly set
forth herein.

            We call your attention to the fact that we are counsel admitted to
practice in the State of Arizona, and we do not express any opinion with respect
to the applicable laws, or the effect or applicability of the laws, of any
jurisdiction other than those of the State of Arizona, the Delaware General
Corporation Law, the General Corporation Law of the State of Nevada, and the
securities laws of the United States of America. In particular, but without
limitation, we do not express any opinion with respect to the Blue Sky or
securities laws of any State or other jurisdiction (other than the federal
securities laws of the United States of America), or any law relating
specifically to telecommunications or patents, trademarks or other intellectual
property rights. The Securities Purchase Agreement, the Warrants and the
Registration Rights Agreement state that they are to be governed by the laws of
the State of Delaware, and the Escrow Agreement states that it is to be governed
by the laws of the State of North Carolina. We are not familiar with those laws,
other than the Delaware General Corporation Law, and render no opinion about
them other than the Delaware General Corporation Law. For purposes of our
opinion we have assumed, with your consent, that the laws of Delaware, other
than the Delawares General Corporation Law, and North Carolina are identical in
all relevant respects to the laws of Arizona. We express no opinion about the
reasonableness of this assumption.

            Based upon and subject to the foregoing, we are of the opinion that:

            1. The Company is a corporation organized, validly existing and in
good standing under the laws of the State of Nevada and has all requisite power
and authority to carry on its business and to own, lease and operate its
properties and assets.
<PAGE>   85
The Company is duly qualified as a foreign corporation to do business and is in
good standing in every jurisdiction in which the Company owns or leases
property, other than those in which the failure so to qualify would not have a
Material Adverse Effect.

            2. The Company has the requisite corporate power and authority to
enter into and perform its obligations under the Agreement and the other
Transaction Documents, to file the Certificate of Designations and to issue the
Preferred Stock and the Warrants, and the shares of Common Stock underlying the
Preferred Stock and the Warrants. The execution and delivery of the Agreement,
and the execution, issuance and delivery of the Transaction Documents by the
Company and the consummation by it of the transactions contemplated thereby have
been duly authorized by all necessary corporate action and no further consent or
authorization of the Company or its Board of Directors or stockholders is
required except for approval of the stockholders of the Company with respect to
the issuance by the Company of more than 19.99% of the outstanding shares of
Common Stock that may be required by the NASDAQ Market (if applicable). The
Agreement and the other Transaction Documents have been duly executed and
delivered, and the Warrants have been duly executed, issued and delivered by the
Company and each of the Agreement and the other Transaction Documents
constitutes valid and binding obligations of the Company enforceable against the
Company in accordance with their respective terms.

            3. Subject to the Company maintaining the requisite number of
authorized shares of Preferred Stock and of Common Stock, the execution,
delivery and performance of the Agreement and the other Transaction Documents by
the Company and the consummation by the Company of the transactions contemplated
thereby, including, without limitation, the issuance of the Securities, do not
and will not (i) result in a violation of the Company's Articles or Bylaws, or
(ii) to our knowledge, conflict with, or constitute a material default (or an
event that with notice or lapse of time or both would become a default) under,
or give to others any rights of termination, amendment, acceleration or
cancellation of, any material agreement, indenture, instrument or any "lock-up"
or similar provision of any underwriting or similar agreement to which the
Company is a party, except for such conflicts, defaults, terminations,
amendments, accelerations and cancellations as would not, individually or in the
aggregate, have a Material Adverse Effect.

            4. The issuance of the Securities in accordance with the Agreement
will be exempt from registration under the Securities Act of 1933, as amended.
When so issued against payment in full of the agreed upon consideration
therefor, the Securities will be duly and validly issued, fully-paid and
nonassessable, and free of any liens, encumbrances and preemptive or similar
rights contained in the Company's Articles or Bylaws or, to our knowledge, in
any agreement to which the Company is party.

            5. To our knowledge, except as disclosed in the Financial Statements
or in a Schedule to the Agreement, there are no claims, actions, suits,
proceedings or investigations that are pending against the Company or its
properties, nor has the Company received any written threat of any such claims,
actions, suits, proceedings or investigations.

To our knowledge, the Company is not a party to or subject to the provisions of
any order, writ, injunction, judgment or decree of any court or government
agency or instrumentality.

            6. To our knowledge, other than as referenced in Schedule 3(c) to
the Agreement, there are no outstanding options, warrants, calls or commitments
of any character whatsoever relating to, or securities, rights or obligations
convertible into or exchangeable for, or giving any right to subscribe for or
acquire any shares of Common Stock or contracts, commitments, understanding, or
arrangements by which the Company is or may become bound to issue additional
shares of Common Stock, or securities or rights convertible or exchangeable into
shares of Common Stock.

            7. The issuance of the Securities will not violate the applicable
listing agreement between the Company and any securities exchange or market on
which the Company's securities are listed.

            This opinion is rendered solely to the Investor in connection with
the transactions contemplated by the Agreement and only the Investor is entitled
to rely hereon. This opinion may not be used or relied on by the Investor for
any other purpose, or by any other person, firm, corporation or entity for any
purpose, without our prior written consent.

                                    Very truly yours,
