Common Stock issuable upon the exercise of this Warrant are referred to as the
"Exercise Shares." This Warrant is subject to the following terms, provisions
and conditions:

     1.  Manner of Exercise; Issuance of Exercise Shares. Subject to the
         -----------------------------------------------
provisions hereof, including, without limitation, the limitations contained in
Sections 2 and 8 hereof, this Warrant may be exercised by the Holder hereof, in
whole or in part, by the surrender of this Warrant, together with a completed
exercise agreement in the form attached hereto (the "Exercise Agreement"), to

principal executive offices (or such other office or agency of the Company as it
may designate by notice to the Holder hereof), and upon payment of the Exercise
Price to the Company in cash, by certified or official bank check or by wire
transfer to the account of the Company. The Exercise Shares so purchased shall
be deemed to be issued to the Holder hereof or such Holder's designee, as the
record owner of such shares, as of the close of business on the date on which
this Warrant shall have been surrendered, the completed Exercise Agreement shall
have been delivered, and payment shall have been made for such Exercise Shares

succeeding business day. The Exercise Shares so purchased shall be delivered to
the Holder hereof within a reasonable time, not exceeding two (2) Trading Days,
after this Warrant shall have been so exercised (the "Delivery Period").

     2.  Period of Exercise. This Warrant shall be exercisable at any time and
         ------------------
from time to time during the period from the date of initial issuance of this
Warrant (the "Issue Date") until 5:00 p.m. New York City time April 19, 2002
(the "Expiration Date"). The period beginning on the Issue Date and ending on

     3.  Mandatory Exercise.

          (a) On no more than three (3) occasions during the Exercise Period
(each a "Mandatory Exercise Date"), the Company may, at its sole discretion, but
subject to satisfaction (or waiver) of all of the conditions set forth in
Section 3(c) hereof, require the Holder to exercise this Warrant in accordance
with the terms set forth below (a "Mandatory Exercise"). No Mandatory Exercise
may occur prior to the date (the "Effective Date") on which the registration
statement (the Registration Statement") that is required to be filed pursuant to
Section 2.1 of the Registration Rights Agreement dated as of the Issue Date
between the Company and the Holder (the "Registration Rights Agreement") is
declared effective by the Securities Exchange Commission ("SEC"). The initial
Mandatory Exercise may not occur until the Holder has sold at least ninety-five
percent (95%) of the shares of Common Stock acquired by it pursuant to the
Securities Purchase Agreement dated as of the Issue Date between the Company and
the Holder (the "Securities Purchase Agreement"). The second and third Mandatory
Exercises may not occur until the Holder has sold at least ninety-five percent
(95%) of the shares of Common Stock acquired by it pursuant to the preceding
Mandatory Exercise. The Holder shall give written notice (a "Sale Notice") to
the Company within three (3) Trading Days after it has sold at least ninety-five
percent (95%) of the Common Stock acquired by it pursuant to the Securities
Purchase Agreement or the first two Mandatory Exercises, as applicable. No
Mandatory Exercise shall occur earlier than the first Trading Day of the
calendar month immediately following the calendar month in which the applicable
Sale Notice was given.

          (b) In order to cause a Mandatory Exercise, the Company must first
deliver to the Holder, on the date that is five (5) Trading Days prior to the
applicable Mandatory Exercise Date, a written notice (the "Mandatory Exercise
Notice"). The Mandatory Exercise Notice shall set forth the Mandatory Exercise
Date to which it relates and the number of shares of Common Stock to be subject
to the Mandatory Exercise (subject to the limitations set forth in Section 3(e)
below) and shall state that, as of the date of such Mandatory Exercise Notice
(the "Mandatory Exercise Notice Date"), all conditions to such Mandatory
Exercise have been met. On each Mandatory Exercise Date, the Company shall issue
to the Holder the number of Exercise Shares specified in the applicable
Mandatory Exercise Notice (subject to the limitations set forth in Section 3(e)
below) and the Holder shall pay the Exercise Price (determined in accordance
with Section 3(d) below) in cash, by certified check or official bank check or
by wire transfer to the account of the Company.

          (c) The Holder's obligation to purchase the Exercise Shares pursuant
to a Mandatory Exercise is conditioned upon the satisfaction by the Company (or
waiver by the Holder) of each of the following events:

              (i) the Company shall have purchased contemporaneously with the
Mandatory Exercise (which purchase is in compliance with applicable Delaware
corporate law) for cash from the Holder (unless the Holder declines such
purchase in writing) at the Per Share Price a number of shares of the Company's
Series A Convertible Preferred Stock (the "Series A Shares") equal to: (A)
twenty percent (20%) of the aggregate Exercise Price to be paid upon the
applicable Mandatory Exercise Date, divided by (B) the Per Share Price. The "Per
Share Price" shall be equal to One Thousand Dollars ($1,000) plus accrued and
unpaid dividends through the date of payment on such Series A Share.

Holder at all times from the Effective Date up to and including the Mandatory
Exercise Date for the resale of all Registrable Securities, as defined in the
Registration Rights Agreement;

              (iii)  the representations and warranties of the Company set forth
in the Securities Purchase Agreement shall be true and correct in all material
respects as of the Mandatory Exercise Notice Date and the Mandatory Exercise
Date as if made on such dates;

              (iv)   the Company shall have complied with or performed in all
material respects all of the agreements, obligations and conditions set forth in
the Securities Purchase Agreement, the Registration Rights Agreement, the
Warrants, the Certificate of Designations (as defined in the Securities Purchase
Agreement) and all other agreements to which both the Company and the Holder are
parties that are required to be complied with or performed by the Company on or
before the Mandatory Exercise Date;

              (v)    the Company shall have delivered to the Holder on the
Mandatory Exercise Date a certificate, signed by an officer of the Company,
certifying that the conditions set forth in this Section 3(c) have been
fulfilled as of the Mandatory Exercise Notice Date and/or the Mandatory Exercise
Date, as applicable, it being understood that the Holder may rely on such
certificate as though it were a representation and warranty of the Company made
in the Securities Purchase Agreement and, in the event of any breach thereof,
shall be entitled to the same remedies as may be available to the Holder in the
event of a breach of any such representation or warranty;

              (vi)   the Company shall have delivered to the Holder an opinion
of Counsel for the Company dated as of the Mandatory Exercise Date, in
substantially the form set forth on Exhibit A;

              (vii)  the Company shall have delivered to the Holder on the
Mandatory Exercise Date a duly executed certificate representing the number of
Exercise Shares determined in accordance with Sections 3(b) and 3(e);

              (viii) the Exercise Shares shall be included for quotation on the
OTC Bulletin Board or on a national securities exchange or on the Nasdaq Stock
Market and no suspension of trading in the Common Stock on such market shall
have occurred during the thirty (30) Trading Day period preceding the applicable
Mandatory Exercise Date;

              (ix)   the Company's revenues shall equal at least Five Hundred

the last completed fiscal quarter for which such revenues have been publicly
announced by a press release or a filing with the SEC as of the applicable
Mandatory Exercise Notice Date.

              (x)   the average closing bid price of the Common Stock on the
then principal market for the Common Stock as reported by Bloomberg Financial
Markets ("Bloomberg") for the periods of five (5) consecutive Trading Days
ending on the Trading Day immediately prior to the applicable Mandatory Exercise
Notice Date and the applicable Mandatory Exercise Date shall be at least Twenty
Cents ($.20).

              (xi)  there shall have been no Change in Control Transaction (as
defined in Section 4(d)(i) below).

          (d) The Exercise Price for a Mandatory Exercise shall equal Eighty
Percent (80%) of the Market Price (as defined in Section 4(d)(ii) below) on the
applicable Mandatory Exercise Date.

          (e) The number of shares of Common Stock subject to a Mandatory
Exercise shall not exceed the least of:

aggregate Exercise Price for any Mandatory Exercise equal to Five Hundred
Thousand Dollars ($500,000);

              (ii)  the number of unexercised Exercise Shares; and

              (iii) the number of shares of Common Stock permitted to be issued

     4.   Certain Agreements of the Company. The Company hereby covenants and
          ---------------------------------
agrees as follows:

          (a) Certain Actions Prohibited. The Company will not, by amendment of
              --------------------------
its charter or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the Holder of this
Warrant in order to protect the economic benefit inuring to the Holder hereof
and the exercise privilege of the Holder of this Warrant against dilution or
other impairment, consistent with the tenor and purpose of this Warrant.

          (b) Consolidation; Merger. In case of any consolidation of the Company
              ---------------------
with, or merger of the Company into, any other corporation, or in case of any
sale or conveyance of all or substantially all of the assets of the Company
other than in connection with a plan of complete liquidation of the Company at
any time during the Exercise Period, then as a condition of such consolidation,
merger or sale or conveyance, adequate provision will be made whereby the Holder
hereof will have the right to acquire and receive upon exercise of this Warrant
in lieu of the Exercise Shares immediately theretofore acquirable upon the
exercise of this Warrant, such securities, cash or assets as may be issued or
payable with respect to or in exchange for the Exercise Shares immediately
theretofore acquirable and receivable upon exercise of this Warrant had such

                                       5
<PAGE>

consolidation, merger or sale or conveyance not taken place. In any such case,
the Company will make appropriate provision to insure that the provisions of
this Section 4 will thereafter be applicable as nearly as may be in relation to
any instrument or securities thereafter deliverable upon the exercise of this
Warrant.

         (c) Notices. In case at any time:
             -------

             (i)   the Company shall declare any dividend upon the Common Stock
payable in shares of stock of any class or make any other distribution (other
than dividends or distributions payable in cash out of retained earnings
consistent with the Company's past practices with respect to declaring dividends
and making distributions) to the holders of the Common Stock;

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

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

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

then, in each such case, the Company shall give to the Holder of this Warrant
(a) notice of the date or estimated date on which the books of the Company shall
close or a record shall be taken for determining the holders of Common Stock
entitled to receive any such dividend, distribution, or subscription rights or
for determining the holders of Common Stock entitled to vote in respect of any
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding-up and (b) in the case of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up, notice of the date (or, if not then known, a reasonable estimate
thereof by the Company) when the same shall take place. Such notice shall also
specify the date on which the holders of Common Stock shall be entitled to
receive such dividend, distribution, or subscription rights or to exchange their
Common Stock for stock or other securities or property deliverable upon such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding-up, as the case may be. Such notice shall be given at
least thirty (30) days prior to the record date or the date on which the
Company's books are closed in respect thereto. Failure to give any such notice
or any defect therein shall not affect the validity of the proceedings referred
to in clauses (i), (ii), (iii) and (iv) above. Notwithstanding the foregoing,
the Company shall publicly disclose the substance of any notice delivered
hereunder prior to delivery of such notice to the Holder hereof.

notice to the contrary. Notwithstanding anything to the contrary contained
herein, the registration rights described in Section 6 hereof are assignable
only in accordance with the provisions of the Registration Rights Agreement.

          (b) Warrant Exchangeable for Different Denominations. This Warrant is

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

          (f) Transfer or Exchange Without Registration. If, at the time of the
              -----------------------------------------
surrender of this Warrant in connection with any transfer, or exchange of this
Warrant, this Warrant (or, in the case of any exercise, the Exercise Shares
issuable hereunder), shall not be registered under the Securities Act and under
applicable state securities or blue sky laws, the Company may require, as a
condition of allowing such transfer or exchange, (i) that the Holder or
transferee of this Warrant, as the case may be, furnish to the Company a written
opinion of counsel (which opinion shall be in form, substance and scope
customary for opinions of counsel in comparable transactions and reasonably
acceptable to the Company) to the effect that such transfer or exchange may be
made without registration under the Securities Act and under applicable state
securities or blue sky laws (the cost of which shall be borne by the Company if
the Company's counsel renders such an opinion), (ii) that the Holder or
transferee execute and deliver to the Company an investment letter in form and

Act; provided that no such opinion, letter, or status as an "accredited
investor" shall be required in connection with a transfer pursuant to Rule 144
under the Securities Act.

        -------------------
assignees thereof) is entitled to the benefit of such registration rights in
respect of the Exercise Shares as are set forth in the Registration Rights
Agreement, including the right to assign such rights to certain assignees, as

         ----------------------------------
contrary contained herein, this Warrant shall not be exercisable by the Holder

inconvenient forum to the maintenance of such suit or proceeding. The Company
further agrees that service of process upon the Company mailed by certified or
registered mail shall be deemed in every respect effective service of process
upon the Company in any such suit or proceeding. Nothing herein shall affect the
Holder's right to serve process in any other manner permitted by law. The
Company agrees that a final non-appealable judgment in any such suit or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on such judgment or in any other lawful manner.

                                  ARTICLE II
                  PURCHASERS' REPRESENTATIONS AND WARRANTIES

     The Purchaser represents and warrants to the Company as follows:

     2.1.  Purchase for Own Account. The Purchaser is purchasing the Securities
           ------------------------
for its own account and not with a view toward, or in connection with, the
public distribution thereof, and will not resell the Securities except pursuant
to sales that are exempt from the registration requirements of the Securities
Act and/or sales that are registered under the Securities Act.  The Purchaser
further represents that it does not have any contract, undertaking, agreement or
arrangement with any person to sell, transfer or grant participation to any
third party with respect to any of the Securities.  The Purchaser

                                       2
<PAGE>

understands that it must bear the economic risk of this investment indefinitely,
unless any disposition of the Securities is registered pursuant to the
Securities Act and any applicable state securities laws or an exemption from
such registration is available, and that the Company has no present intention of
disposing of any such Securities other than as contemplated by the Registration
Rights Agreement. By making the representations in this Section 2.1, the
Purchaser does not agree to hold any Securities for any minimum or other
specific term and reserves the right to dispose of any or all of the Securities
at any time in accordance with or pursuant to a registration statement or an
exemption from registration under the Securities Act and other applicable state
securities laws and, without limiting the foregoing, the Purchaser may transfer
a portion of the Purchased Shares to one or more charitable entities and the
Company shall cooperate in effecting the transfer and reissuance of any such
transferred stock certificates.

     2.2.  Accredited Investor Status. The Purchaser is an "accredited investor"
           --------------------------
as that term is defined in SEC Rule 501(a) of Regulation D, as presently in
effect, under the Securities Act.

     2.3.  Reliance on Exemptions. The Purchaser understands that the Purchased
           ----------------------
Securities are being offered and sold to the Purchaser in reliance upon specific
exemptions from the registration requirements of the United States federal and
state securities laws and that the Company is relying upon the truth and
accuracy of the representations and warranties of the Purchaser set forth herein
in order to determine the availability of such exemptions and the eligibility of
the Purchaser to acquire the Securities.

     2.4.  Information. The Purchaser has been furnished all materials relating
           -----------
to the business, finances and operations of the Company and materials relating
to the offer and sale of the Purchased Securities which have been requested by
the Purchaser. The Purchaser has been afforded the opportunity to ask questions
of the Company and has received what the Purchaser believes to be satisfactory
answers to any such inquiries. The Purchaser understands and acknowledges that
such discussions, as well as any written information issued by the Company, (i)
were intended to describe the aspects of the Company's business and prospects
which the Company believes to be material, but were not necessarily an
exhaustive description, and (ii) may have contained forward-looking statements
involving known and unknown risks and uncertainties which may cause the
Company's actual results in future periods or plans for future periods to differ
materially from what was anticipated and that, except as specifically set forth
elsewhere herein, no representations or warranties were or are being made with
respect to any such forward-looking statements or the probability of achieving
any of the results projected in any of such forward-looking statements.  Neither
such materials or inquiries nor any other due diligence investigation conducted
by the Purchaser nor any of its representations, warranties, covenants or
agreements shall modify, amend or affect the Purchaser's right to rely on the
Company's representations and warranties contained in Article III.  The
Purchaser understands that the Purchaser's investment in the Purchased
Securities involves a high degree of risk.

                                       3
<PAGE>

     2.5. Governmental Review. The Purchaser understands that no United States
          -------------------
federal or state agency or any other government or governmental agency has
passed upon or made any recommendation or endorsement of the Securities or an
investment therein.

     2.6. Transfer or Resale. The Purchaser understands that (i) except as
          ------------------
provided in the Registration Rights Agreement, the Securities have not been and
are not being registered under the Securities Act or any state securities laws,
and may not be transferred unless subsequently registered thereunder or an
exemption from such registration is available (which exemption the Company
expressly agrees may be established as contemplated in clauses (b) and (c) of
Section 5.1 hereof or as otherwise may be permissible under the Securities Act);
(ii) any sale of such Securities made in reliance on Rule 144 under the
Securities Act (or a successor rule) ("Rule 144") may be made only in accordance
                                       --------
with the terms of said Rule and further, if said Rule is not applicable, any
resale of such Securities without registration under the Securities Act may
require compliance with some other exemption under the Securities Act or the
rules and regulations of the SEC thereunder; and (iii) neither the Company nor
any other person is under any obligation to register such Securities under the
Securities 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).

     2.7. Legends. The Purchaser understands that, subject to Article V hereof,
          -------
the certificates for the Purchased Shares and the Warrant and, until such time
as the Warrant Shares have been registered under the Securities Act as
contemplated by the Registration Rights Agreement or otherwise, may be sold by
the Purchaser pursuant to Rule 144 or otherwise without registration, the
certificates for the Warrant Shares will bear a restrictive legend (the
"Legend") in the following form:
 ------

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN

     REGISTRATION REQUIREMENTS OF THOSE LAWS.

Except for the Legend in accordance with this Section 2.7 and Section 5.1
hereof, the Securities shall bear no other legend.

     2.8. Authorization; Enforcement.  This Agreement and the Registration

on behalf of the Purchaser and are valid and binding agreements of the Purchaser

                                                          -------------
Schedule 3.7 sets forth a complete list of the SEC Documents.  The Company has
------------
delivered or made available to the Purchaser true and complete copies of the SEC
Documents.  As of their respective dates, the SEC Documents complied in all
material respects with the requirements of the Exchange 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.  None of the statements made in any such SEC

                                       8
<PAGE>

Document is, or has been, required to be updated or amended under applicable

regulatory organization or body pending or, to the knowledge of the Company or
any of its subsidiaries, threatened against or affecting the Company, any of its
subsidiaries, or any of their respective directors or officers in their
capacities as such, wherein an unfavorable decision, ruling or finding could
have a Material Adverse Effect or would adversely affect the transactions
contemplated by this Agreement or any of the documents contemplated hereby or
which would 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 such other documents.  To the Company's knowledge, there are no facts
which, if known by a potential claimant or governmental agency or authority,
could give rise to a claim or proceeding against the Company or any of its
subsidiaries which, if asserted or conducted with results unfavorable to the
Company or any of its subsidiaries, could have a Material Adverse Effect.

     3.10. Disclosure. No information relating to or concerning the Company set
           ----------
forth in this Agreement or provided to the Purchaser in connection with the
transactions contemplated hereby contains an untrue statement of a material fact
or omits to state a material fact necessary in order to make the statements made
herein or therein, in light of

                                       9
<PAGE>

the circumstances under which they were made, not misleading. No event or
circumstance has occurred or exists with respect to the Company or its
subsidiaries or their respective businesses, properties, prospects, operations
or financial conditions, which has not been publicly disclosed other than the
transactions contemplated hereby. There is no fact (other than matters of a
general economic or political nature which do not uniquely affect the business,
properties, operations or financial condition of the company) known to the
Company that has not been disclosed by the Company to the Purchaser and to the
public that might reasonably be expected to have or result in a material effect
on the business, properties, operations or financial condition of the Company
and its subsidiaries taken as a whole or have a material effect on the ability
of the Company to conduct its business after the Closing in all material
respects as currently conducted.

     3.11.  Acknowledgment Regarding Purchaser's Purchase of the Securities. The
            ---------------------------------------------------------------
Company acknowledges and agrees that the Purchaser is acting independently and
is not acting as a financial advisor 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 Purchaser and the Company is "arms-
                                                                       ----
length", and that any statement made by the Purchaser, or any of its
------
representatives or agents, in connection with this Agreement or the transactions
contemplated hereby, other than the representations and warranties of the
Purchaser contained herein, is not advice or a recommendation, is merely
incidental to the Purchaser's purchase of the Securities and has not been relied
upon in any way by the Company, its officers, directors or other
representatives.  The Company further represents to the Purchaser that the
Company's decision to enter into this Agreement and the transactions
contemplated hereby has been based solely on an independent evaluation by the
Company and its representatives.

     3.12.  No General Solicitation. Neither the Company nor any person acting
            -----------------------
on behalf of the Company has conducted any "general solicitation," as described
                                            --------------------
in Rule 502(c) under Regulation D, with respect to any of the Securities being
offered hereby.

     3.13.  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 that would prevent the parties hereto from
consummating the transactions contemplated hereby pursuant to an exemption from
registration under the Securities Act pursuant to the provisions of Regulation
D.  The transactions contemplated hereby are exempt from the registration
requirements of the Securities Act, assuming the accuracy of the representations
and warranties herein contained of the Purchaser to the extent relevant for such
determination.

     3.14.  No Brokers. The Company has taken no action which would give rise to
            ----------
any claim by any person for brokerage commissions, finder's fees or similar
payments (collectively, "Transaction Fees") by the Purchaser relating to this
                         ----------------
Agreement or the transactions contemplated hereby, provided that, although the
Company does not believe it has any obligation to Nutmeg Securities, Ltd. d/b/a
I.F.G., Inc. ("IFG") in connection

                                       10
<PAGE>

with this Agreement or the transactions contemplated hereby, no representation
or warranty is made with respect thereto; provided further that the Company
hereby indemnifies the Purchaser and its affiliates against all liability and
costs (including without limitation reasonable attorney's fees and expenses)
arising from any claim by IFG or any other person for Transaction Fees arising
from this Agreement or the transactions contemplated hereby.

     3.15.  Acknowledgment of Dilution. The potential number of Warrant Shares,
            --------------------------
Remedy Shares and Additional Shares issuable to the Purchaser 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 terms of this Agreement and the
transactions contemplated hereby and the nature of the securities being sold
hereunder and recognize that they have a potential dilutive effect. The board of
directors of the Company has concluded in its good faith business judgment that
the issuance of the Securities as contemplated hereby is in the best interests
of the Company. The Company acknowledges that its obligation to issue the Remedy
Warrant, Warrant Shares, Additional Share Warrants, Additional Shares and Remedy
Shares in accordance with the terms of the applicable Investment Agreement is
binding upon it and enforceable regardless of the dilution that such issuance
may have on the ownership interests of other stockholders.

     3.16.  Intellectual Property. Except as set forth in the SEC Documents, to
            ---------------------
the Company's knowledge each of the Company and its subsidiaries, owns or
possesses adequate and enforceable rights to use all patents, patent
applications, trademarks, trademark applications, trade names, service marks,
copyrights, copyright applications, licenses, know-how (including trade secrets
and other unpatented and/or unpatentable proprietary or confidential
information, systems or procedures) and other similar rights and proprietary
knowledge (collectively, "Intangibles") used or necessary for the conduct of its
                          -----------
business as now being conducted and as described in the Company's SEC Documents.
Except as set forth in the SEC Documents, neither the Company nor any subsidiary
of the Company infringes on or is in conflict with any right of any other person
with respect to any Intangibles nor is there any claim of infringement made by a
third party against or involving the Company or any of its subsidiaries, which
infringement, conflict or claim, individually or in the aggregate, if the
subject of an unfavorable decision, ruling or finding, would have a Material
Adverse Effect. Except as set forth in the SEC Documents, none of the
Intangibles used in the Company's business is expected to expire or terminate
within two years from the date of this Agreement, except where such expiration
or termination would not result, either individually or in the aggregate, in a
Material Adverse Effect. The Company and its subsidiaries have taken reasonable
security measures to protect the secrecy, confidentiality and value of all of
their Intangibles.

     3.17.  Foreign Corrupt Practices. Neither the Company, nor any of its
            -------------------------
subsidiaries, nor any director, officer, agent, employee or other person acting
on behalf of the Company or any subsidiary has, in the course of his actions
for, or on behalf of, the

                                       11
<PAGE>

Company, used any corporate funds for any unlawful contribution, gift,
entertainment or other unlawful expenses relating to political activity; made
any direct or indirect unlawful payment to any foreign or domestic government
official or employee from corporate funds; violated or is in 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. Without limiting the
generality of the foregoing, the Company and its subsidiaries have not directly
or indirectly made or agreed to make (whether or not said payment is lawful) any
payment to obtain, or with respect to, sales other than usual and regular
compensation to its or their employees and sales representatives with respect to
such sales.

     3.18.  Officers and Directors. No executive officer (as defined in Rule
            ----------------------
501(f) promulgated under the Securities Act) or director of the Company or any
of its subsidiaries, is, or is now expected to be, in violation of any material
term of any employment contract, confidentiality, disclosure or proprietary
information agreement, non-competition agreement, or any other contract or
agreement or any restrictive covenant between such officer or director and the
Company and its subsidiaries or between the such officer or director and any
other third party. No officer or director has, to the knowledge of the Company
and its subsidiaries, any intention to terminate or limit his or her employment
with, or services to, the Company or any of its subsidiaries, nor is any such
officer subject to any constraints which would cause such person to be unable to
devote his full time and attention to such employment or services.

     3.19.  Solvency. As of the Closing, the Company (i) has not incurred and
            --------
does not intend to incur, or believe that it will incur, debts beyond its
ability to pay such debts as they become due, (ii) owns assets, the fair
saleable value of which is greater than the total amount of its liabilities
(including contingent liabilities), and (iii) has and intends to have capital
that is not unreasonably small in relation to its business as presently
conducted and as proposed to be conducted.

     3.20.  Title to Properties; Liens and Encumbrances. The Company has good
            -------------------------------------------
and marketable title to all of its material properties and assets, both real and
personal, and has good title to all its leasehold interests, in each case
subject only to mortgages, pledges, liens, security interests, conditional sale
agreements, encumbrances or charges created in the ordinary course of business.

     3.21.  Employment Matters. The Company is in compliance in all material
            ------------------
respects with all presently applicable provisions of the Employee Retirement
Income Security Act of 1974, as amended, including the regulations and published
interpretations thereunder ("ERISA"); no "reportable event" (as defined in
                             -----        ----------------
ERISA) has occurred with respect to any "pension plan" (as defined in ERISA) for
                                         ------------
which the Company would have any liability; the Company has not incurred and
does not expect to incur liability under (i) Title IV of ERISA with respect to
termination of, or withdrawal from, any "pension plan" or (ii) Sections 412 or
4971 of the Internal Revenue Code of 1986, as amended, including the regulations
and published interpretations thereunder (the "Code"); and each "pension
                                               ----              -------

                                       12
<PAGE>

plan" for which the Company would have any liability that is intended to be
----
qualified under Section 401(a) of the Code is so qualified in all material
respects and nothing has occurred, whether by action or by failure to act, which
would cause the loss of such qualification. Neither the Company nor any of its
subsidiaries is involved in any union labor dispute nor, to the knowledge of the
Company or any of its subsidiaries, is any such dispute threatened. To the
knowledge of the Company, none of the Company's or its subsidiaries' employees
is a member of a union which relates to such employee's relationship with the
Company. Neither the Company nor any of its subsidiaries is a party to a
collective bargaining agreement, and the Company and its subsidiaries believe
that their relations with their employees are good.

     3.22.  Insurance. The Company maintains property and casualty, general
            ---------
liability, personal injury, director and officer liability and other similar
types of insurance with financially sound and reputable insurers that is
adequate, consistent with industry standards and the historical claims
experience of the Company and its subsidiaries. The Company has not received
notice from, and has no knowledge of any threat by, any insurer (that has issued
any insurance policy to the Company or any of its subsidiaries) that such
insurer intends to deny coverage under or cancel, discontinue or not renew any
insurance policy covering the Company or any of its subsidiaries presently in
force.

     3.23.  Taxes. Except as set forth in Schedule 3.23, all applicable tax
            -----                         -------------
returns required to be filed by the Company and each of its subsidiaries have
been prepared and filed in compliance with all applicable laws, or if not yet
filed have been granted extensions of the filing dates which extensions have not
expired, and all taxes, assessments, fees and other governmental charges upon
the Company, its subsidiaries, or upon any of their respective properties,
income or franchises, shown in such returns and on assessments received by the
Company or its subsidiaries to be due and payable have been paid, or adequate
reserves therefor have been set up if any of such taxes are being contested in
good faith; or if any of such tax returns have not been filed or if any such
taxes have not been paid or so reserved for, the failure to so file or to pay
would not in the aggregate have a Material Adverse Effect.

     3.24.  Internal Controls. The Company maintains a system of internal
            -----------------
accounting controls sufficient to provide reasonable assurances that (i)
transactions are executed in accordance with management's general or specific
authorization; (ii) transactions are recorded as necessary to permit preparation
of financial statements in conformity with generally accepted accounting
principles and to maintain accountability for assets; (iii) access to assets is
permitted only in accordance with management's general or specific
authorization; and (iv) the recorded accountability for assets is compared with
existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

     3.25.  Contracts. The SEC Documents, as supplemented by Schedule 3.25
            ---------                                        -------------
hereto, contain a complete and accurate list of all material undischarged
written or 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 bound or to which any

                                       13
<PAGE>

of the properties or assets of the Company or any subsidiary is subject (each a
"Contract"). None of the Company, its subsidiaries or, to the knowledge of the
 --------
Company, any of the other parties thereto, is in breach or violation of any
Contract, which breach or violation relates to indebtedness for borrowed money,
is with respect to an obligation in excess of Seventy-Five Thousand Dollars
($75,000) or would have a Material Adverse Effect. No event, occurrence or
condition exists which, with the lapse of time, the giving of notice, or both,
or the happening of any further event or condition, would become a breach or
default by the Company or its subsidiaries under any Contract which breach or
default would have a Material Adverse Effect.

     3.26.  Year 2000 Processing. The computer systems used by the Company and
            --------------------
its subsidiaries (the "Systems"), both hardware and software, are in good
                       -------
working order. The occurrence of the year 2000 has not materially and adversely
affected the Systems of the Company, its subsidiaries, or their business, and no
material expenditures in excess of currently budgeted items are or will be
required in order to cause such Systems to operate properly as a result of the
change of the year 1999 to 2000. The Company and its subsidiaries have resolved
any issues discovered as a result of year 2000 inquires and compliance testing
or otherwise known to the Company.

     3.27.  Environmental Matters. Neither the Company and its subsidiaries,
            ---------------------
nor to the Company's knowledge, any predecessor in interest, has ever caused or
permitted any Hazardous Material (as defined below) to be released, treated or
disposed of on, at, under or within any real property owned, leased or operated
by the Company and its subsidiaries or any predecessor in interest, and no such
real property has ever been used (either by the Company and its subsidiaries or
any predecessor in interest ) as a treatment, storage or disposal site for any
Hazardous Material. The Company has no liabilities with respect to Hazardous
Materials, and to the Company's knowledge, no facts or circumstances exist which
could give rise to liabilities with respect to Hazardous Materials, which could
have any reasonable likelihood of having a Material Adverse Effect on the
Company. For purposes of this Agreement "Hazardous Materials" shall mean (a) any
                                         -------------------
pollutants or contaminations, (b) any asbestos or insulation or other material
composed of or containing asbestos and (c) any petroleum product and any
hazardous, toxic or dangerous waste, substance or material defined as such in,
or for purposes of, the Comprehensive Environmental Response, Compensation and
Liability Act, any so-called "Superfund" or "Superlien" law, or (d) any other
                              ---------      ---------
applicable federal, state, local or other statute, law, ordinance, code, rule,
regulation, order or decree concerning the protection of human health or the
environment or otherwise regulating, relating to, or imposing liability or
standards of conduct concerning, any hazardous, toxic or dangerous waste,
substance or material, as now or at any time hereafter in effect.

     3.28.  Regulatory Permits. Except for Permits (as defined below) the
            ------------------
absence of which would not result, either individually or in the aggregate, in a
Material Adverse Effect, the Company and its subsidiaries possess all
certificates, authorizations and permits issued by the appropriate federal,
state or foreign regulatory authorities necessary to conduct their respective
businesses (the "Permits"), and neither the Company nor any
                 -------

                                       14
<PAGE>

such Subsidiary has received any notice of proceedings relating to the
revocation or modification of any such Permit.

     3.29.  Transactions With Affiliates. Except as set forth in the SEC
            ----------------------------
Documents and other than the grant of stock options disclosed on Schedule 3.29,
                                                                 -------------
none of the officers, directors or employees of the Company is presently a party
to any transaction with the Company or any of its subsidiaries (other than for
services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any such officer, director or employee or, to the
knowledge of the Company, any corporation, partnership, trust or other entity in
which any such officer, director, or employee has a substantial interest or is
an officer, director, trustee or partner.

     3.30.  Application of Takeover Protections. The Company and its board of

           -----------------
issue a certificate without any legend to the holder of any Security upon which

issued without the Legend if (a) the sale of such Security is registered under
the Securities Act, (b) such holder provides the Company with an opinion of
counsel, in form, substance and scope customary for opinions of counsel in
comparable transactions to the effect that a public sale or transfer of such

Legend has been removed, or which were originally issued without the Legend,

connection with such sale or in compliance with an exemption from the
registration requirements of the Securities 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 resale of
such Security is suspended or a supplement or amendment thereto is required by
applicable securities laws, then upon reasonable advance notice to each
Purchaser holding such Security, the Company may require that the Legend be
placed on any such Security that cannot then be sold pursuant to an effective
registration statement or Rule 144 or with respect to which the opinion referred
to in clause (b) 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 (b) next above.

Warrant Shares in such amounts as specified from time to time by the Purchaser
to the Company upon, and in accordance with the terms of the Warrant. Such
certificates shall bear a legend only in the form of the Legend and only to the
extent permitted by Section 5.1 above. The Company warrants that no instruction
other than such instructions referred to in this Article V, and no stop transfer
instructions other than stop transfer instructions to give effect to Section 2.6
hereof in the case of the Warrant Shares prior to registration under the
Securities Act, will be given by the Company to its transfer agent and, subject
to applicable law, the Securities shall otherwise be freely transferable on the
books and records of the Company. Nothing in this Section shall affect in any
way the Purchaser's obligations and agreement set forth in Section 5.1 hereof to
resell the Securities 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 applicable securities laws.
Without limiting any other rights of the Purchaser or obligations of the
Company, if (i) the Purchaser provides the Company with an opinion of counsel,
to the effect that the Securities to be sold or transferred may be sold or
transferred pursuant to an exemption from registration or (ii) the Purchaser
transfers Securities pursuant to Rule 144, the Company shall permit the
transfer, and, in the case of Warrant Shares promptly instruct its transfer
agent to issue one or more certificates in such name and in such denomination as
specified by the Purchaser in order to effect such a transfer or sale.

          (b)    Purchaser shall exercise its right to exercise the Warrant by
faxing an executed and completed Form of Exercise Agreement to Purchase to the
Company, and delivering within two (2) business days thereafter, the original
Form of Exercise Agreement to Purchase (and the related original Warrant and
exercise price in the case of a non-cashless exercise of the Warrant) to the
Company by hand delivery or by express courier, duly endorsed. Each date on
which a completed Form of Exercise Agreement to Purchase is faxed in accordance
with the provisions of the Warrant shall be deemed an "Exercise Date." The
                                                       -------------
Company will transmit the certificates representing the Common Stock issuable
upon exercise of any Warrant (together with Warrants not so exercised) to the
Purchaser via express courier as soon as practicable, but no later than three
(3) business days after the Exercise Date (each such delivery date, is referred
to herein as a "Delivery Date"). For purposes of this Agreement, exercise of
                -------------
the Warrant shall be deemed to have been made immediately prior to the close of
business on the Exercise Date.

          (c)    In lieu of delivering physical certificates representing the
Common Stock issuable upon the conversion of, or in lieu of dividends on, the
Shares of Common Stock or upon the exercise of the Warrant(s), provided the
Company's transfer agent is participating in the Depositary Trust Company
("DTC") Fast Automated Securities Transfer program, on the written request of
  ---
the Purchaser, who shall have previously instructed the Purchaser's prime broker
to confirm such request to the Company's transfer

prime broker with DTC through its Deposit Withdrawal Agent Commission ("DWAC")
                                                                        ----

            --------------------------------
of a Purchaser in the exercise of any power, right or privilege hereunder shall

other party hereto for a breach of this Agreement prior to or relating to the
termination.

agrees as follows:

          (a) Certain Actions Prohibited.  The Company will not, by amendment of

its charter or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the Holder of this
Warrant in order to protect the economic benefit inuring to the Holder hereof
and the exercise privilege of the Holder of this Warrant against dilution or
other impairment, consistent with the tenor and purpose of this Warrant.

          (b) Consolidation; Merger. In case of any consolidation of the Company

with, or merger of the Company into, any other corporation, or in case of any
sale or conveyance of all or substantially all of the assets of the Company
other than in connection with a plan of complete liquidation of the Company at
any time during the Exercise Period, then as a condition of such consolidation,
merger or sale or conveyance, adequate provision will be made whereby the

Holder hereof will have the right to acquire and receive upon exercise of this
Warrant in lieu of the Exercise Shares immediately theretofore acquirable upon
the exercise of this Warrant, such securities, cash or assets as may be issued
or payable with respect to or in exchange for the Exercise Shares immediately
theretofore acquirable and receivable upon exercise of this Warrant had such
consolidation, merger or sale or conveyance not taken place. In any such case,
the Company will make appropriate provision to insure that the provisions of
this Section 4 will thereafter be applicable as nearly as may be in relation to
any instrument or securities thereafter deliverable upon the exercise of this
Warrant.

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

liquidation or winding-up and (b) in the case of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up, notice of the date (or, if not then known, a reasonable estimate

specify the date on which the holders of Common Stock shall be entitled to
receive such dividend, distribution, or subscription rights or to exchange their
Common Stock for stock or other securities or property deliverable upon such
reorganization, reclassification, consolidation, merger, sale, dissolution,

least thirty (30) days prior to the record date or the date on which the
Company's books are closed in respect thereto.  Failure to give any such notice
or any defect therein shall not affect the validity of the proceedings referred
to in clauses (i), (ii), (iii) and (iv) above.  Notwithstanding the foregoing,
the Company shall publicly disclose the substance of any notice delivered
hereunder prior to delivery of such notice to the Holder hereof.

the Holder hereof are transferable, in whole or in part, upon surrender of this

exchangeable, upon the surrender hereof by the Holder hereof at the office or
agency of the Company referred to in Section 5(e) below, for new Warrants of
like tenor of different denominations representing in the aggregate the right to

Price therefor as shall be designated by the Holder hereof at the time of such
surrender.

          (c)  Replacement of Warrant.  Upon receipt of evidence reasonably

surrender of this Warrant in connection with any transfer, or exchange of this
Warrant, this Warrant (or, in the case of any exercise, the Exercise Shares
issuable hereunder), shall not be registered under the Securities Act and under
applicable state securities or blue sky laws, the Company may require, as a
condition of allowing such transfer or exchange, (i) that the Holder or
transferee of this Warrant, as the case may be, furnish to the Company a written
opinion of counsel (which opinion shall be in form, substance and scope
customary for opinions of counsel in comparable transactions and reasonably
acceptable to the Company) to the effect that such transfer or exchange may be
made without registration under the Securities Act and under applicable state
securities or blue sky laws (the cost of which shall be borne by the Company if

transferee execute and deliver to the Company an investment letter in form and

"accredited investor" as defined in Rule 501(a) promulgated under the Securities

or subject to a Mandatory Exercise by the Company to the extent (but only to the
extent) that such exercise by the Holder or Mandatory Exercise would result in

inconvenient forum to the maintenance of such suit or proceeding. The Company
further agrees that service of process upon the Company mailed by certified or
registered mail shall be deemed in every respect effective service of process
upon the Company in any such suit or proceeding.  Nothing herein shall affect

Company agrees that a final non-appealable judgment in any such suit or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on such judgment or in any other lawful manner.
