Shares for the Purchaser's own account and not with a present view towards the
distribution thereof. The Purchaser understands and acknowledges that the
Purchaser must bear the economic risk of this investment indefinitely, unless

answers to any such inquiries. Neither such inquiries nor any other due
diligence investigation conducted by the Purchaser or its counsel or any of its
representatives shall modify, amend or affect the Purchaser's right to rely on
the Company's representations and warranties contained in Section 4 below.

         c.       Governmental Review. The Purchaser understands that no United
States federal or state agency or any other government or governmental agency

         d.       Authorization; Enforcement. The Purchaser has the requisite
power and authority to enter into and perform its obligations under this
Agreement and to purchase the Shares in accordance with the terms hereof. This
Agreement has been duly and validly authorized, executed and delivered on
behalf of the Purchaser and is a valid and binding agreement of the Purchaser
enforceable against the Purchaser in accordance with its terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer and other laws affecting creditors' rights and remedies generally and
to general principles of equity (regardless of whether enforcement is sought in
a proceeding at law or in equity).

         e.       Transfer or Resale. The Purchaser understands that (i) except
as provided in Section 5(k), the Shares have not been and are not being
registered under the Securities Act or any state securities laws, and may not
be transferred unless (a) subsequently registered thereunder, (b) the Purchaser
shall have delivered to the Company an opinion of counsel reasonably acceptable
to the Company (which opinion shall be in form, substance and scope customary
for opinions of counsel in comparable transactions) to the effect that the
Shares to be sold or transferred may be sold or transferred under an exemption
from such registration, or (c) sold under Rule 144 promulgated under the
Securities Act (or a successor rule); and (ii) neither the Company nor any
other person is under any obligation to register such Shares 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
the registration rights in Section 5(k). Notwithstanding the foregoing, no such
registration statement or opinion of counsel shall be necessary for a transfer
by the Purchaser to its stockholders in accordance with their interest in the
corporation.

         f.       Legends. The Purchaser understands that the Shares and, until
such time as the Shares have been registered under the Securities Act as
contemplated by the registration rights in Section 5(k) or otherwise may be
sold by the Purchaser under Rule 144, the certificates for the Shares will bear
a restrictive legend in substantially the following form:



                                       3
<PAGE>   4

                  The securities represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended, or
                  the securities laws of any state of the United States. The
                  securities represented hereby may not be offered or sold in
                  the absence of an effective registration statement for the
                  securities under applicable securities laws unless offered,
                  sold or transferred under an available exemption from the
                  registration requirements of those laws.

         The legend set forth above shall be removed and the Company shall
issue a certificate without such legend to the holder of any Shares upon which
it is stamped, if, (a) the sale of any such Shares is registered under the
Securities Act, (b) such holder provides the Company with an opinion of
counsel, in form and substance customary for opinions of counsel in comparable
transactions, to the effect that a public sale or transfer of any such Shares
may be made without registration under the Securities Act or (c) such holder
provides the Company with reasonable assurances that any such Shares can be
sold under Rule 144. The Purchaser agrees to sell all Shares, including those
represented by a certificate(s) from which the legend has been removed,
pursuant to an effective registration statement or under an exemption from the
registration requirements of the Securities Act. The legend shall be removed
when such Shares may be sold pursuant to an effective registration statement or
sold under Rule 144(k).

         g.       Accredited Investor Status. The Purchaser is an "accredited
investor" as that term is defined in Rule 501(a) of Regulation D ("Regulation
D") promulgated by the United States Securities and Exchange Commission (the
"SEC") under the Securities Act. The Purchaser is not registered as a broker or
dealer under Section 15(a) of the Securities Exchange Act of 1934, as amended,
or a member of the National Association of Securities Dealers.

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

4.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         The Company represents and warrants to the Purchaser as follows:

         a.       Organization and Qualification. The Company is a corporation,
and each of its subsidiaries is an entity, duly organized and existing under
the laws of the jurisdiction in which it is organized, and has the requisite
corporate power to own its properties and to carry on its business as now being
conducted. The Company and each of its subsidiaries is duly qualified as a
foreign entity 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. The SEC Documents (as hereinafter defined) set



                                       4
<PAGE>   5

forth the name of each of the Company's subsidiaries and its jurisdiction of
organization. Each of the Company's subsidiaries are wholly-owned.

         b.       Authorization; Enforcement. (i) The Company has the requisite
corporate power and authority to enter into and perform its obligations under
this Agreement and to issue and sell the Shares in accordance with the terms
hereof; (ii) the execution, delivery and performance of this Agreement by the
Company and the consummation by it of the transactions contemplated hereby
(including, without limitation, the issuance and sale of the Shares) 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 has been duly executed and delivered by the
Company; and (iv) this Agreement constitutes the valid and binding obligation
of the Company enforceable against the Company in accordance with their
respective terms, subject to applicable bankruptcy, insolvency, reorganization,
moratorium, fraudulent transfer and other laws affecting creditors' rights and
remedies generally and to general principles of equity (regardless of whether
enforcement is sought in a proceeding at law or in equity).

         c.       Capitalization. As of the date hereof, the authorized capital
stock of the Company consists of 25,000,000 shares, consisting of two classes:
22,500,000 shares of Common Stock and 2,500,000 shares of preferred stock, par
value $.01 per Share (the "Preferred Stock"). According to a certificate from
the Company's transfer agent dated November 12, 2000, an aggregate of
11,887,307 shares of the Company's Common Stock were issued and outstanding as
of the date of such transfer agent certificate. No shares of the Company's
Preferred Stock are outstanding as of the date hereof. As of the date hereof,
there is an aggregate of 4,630,599 shares of the Company's Common Stock
reserved for issuance under the Company's stock option plans and employee stock
purchase plan. All of such outstanding shares of the Company's capital stock
have been, or upon issuance will be, validly issued, fully paid and
nonassessable. Except as set forth in this Section 4(c) or on the disclosure
schedule (the "Schedule") referencing this Section 4(c), no shares of capital
stock of the Company (including the Shares) or any of its subsidiaries are
subject to preemptive rights or any other similar rights of the stockholders of
the Company or any liens or encumbrances created or incurred by the Company.
Except for the Shares and as disclosed in this Section 4(c) or Schedule 4(c),
as of the 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 or exercisable
or exchangeable for, any shares of capital stock of the Company or any of its
subsidiaries, or arrangements by which the Company or any of its subsidiaries
is or may become bound to issue additional shares of capital stock of the
Company or such subsidiaries, and (ii) there are no agreements or arrangements
under which the Company or any of its subsidiaries is obligated to register the
sale of any of its or their securities under the Securities Act (except as
provided in Section 1.04(d) and 1.09 of the Purchase Agreement and the
Registration Rights Agreement, dated February 18, 2000 (the "Registration
Rights Agreement"), among the Company, the Purchaser and the other investors
identified therein). Except as set forth on Schedule 4(c), there are no
securities or instruments containing price-based antidilution or similar
provisions that may be triggered by the issuance of the Shares in accordance
with the terms of this Agreement or the Registration Rights Agreement and the
holders of the securities and instruments listed on such Schedule 4(c) have
waived any rights they may have under any such antidilution or similar




                                       5
<PAGE>   6





provisions in connection with the issuance of the Shares in accordance with the
terms of this Agreement or the Registration Rights Agreement. The Company has
made available to the Purchaser and counsel for the Purchaser true and correct
copies of the Company's Certificate of Incorporation as in effect on the date
hereof ("Certificate of Incorporation"), the Company's By-laws as in effect on
the date hereof (the "By-laws") and all other instruments and agreements
governing securities convertible into or exercisable or exchangeable for
capital stock of the Company, except for stock options granted under any
employee benefit plan or director stock option plan of the Company.

         d.       Issuance of Shares. The Shares are duly authorized and when
issued and paid for in accordance with the terms hereof, will be validly
issued, fully paid and non-assessable, and free from all taxes, liens, claims
and encumbrances, and will not be subject to preemptive rights or other similar
rights of stockholders of the Company and will not impose personal liability
upon the holder thereof.

         e.       No Conflicts. The execution, delivery and performance of this
Agreement by the Company, and the consummation by the Company of the
transactions contemplated hereby and thereby (including, without limitation,
the issuance and sale of the Shares) will not (i) conflict with or result in a
violation of the Certificate of Incorporation or By-laws 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 United States federal and state securities laws and
regulations and AMEX 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, with respect to clause (ii), for
such conflicts, defaults, terminations, amendments, accelerations,
cancellations and violations as would not, individually or in the aggregate,
have a Material Adverse Effect). Neither the Company nor any of its
subsidiaries is in violation of its Certificate of Incorporation, By-laws and
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 actual or possible violations,
defaults or rights as would not, individually or in the aggregate, have a
Material Adverse Effect. The businesses of the Company and its subsidiaries are
not being conducted in violation of any law, ordinance or regulation of any
governmental entity, except for actual or possible violations, if any, the
sanctions for which either individually or in the aggregate would not have a
Material Adverse Effect. Except as specifically contemplated by this Agreement
and as required under the Securities Act and any applicable state securities
laws, the Company is not required to obtain any consent, approval,
authorization or order of, or make any filing or registration with, any court
or governmental agency or any regulatory or self regulatory agency in order for
it to execute, deliver or perform any of its obligations under this Agreement
(including, without limitation, the issuance and sale of the Shares as provided
hereby) in accordance with the terms hereof. The Company is not in violation of
the listing requirements of the AMEX and does not reasonably anticipate that
the



                                       6
<PAGE>   7



Common Stock will be delisted by AMEX in the foreseeable future based on its
rules (and interpretations thereof) as currently in effect.

         f.       SEC Documents; Financial Statements. Except for the failure
to timely file a required report on Form 8-K in connection with the acquisition
of Prescient Technologies, Inc., since January 1998, the Company has timely
filed all reports, schedules, forms, statements and other documents required to
be filed by it with the SEC pursuant to the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and has filed all registration statements and
other documents required to be filed by it with the SEC pursuant to the
Securities Act (all of the foregoing filed prior to the date hereof, and all
exhibits included therein and financial statements and schedules thereto and
documents incorporated by reference therein, being hereinafter referred to
herein as the "SEC Documents"). The Company has made available to the Purchaser
and to counsel for the Purchaser true and complete copies of the SEC Documents
not filed on EDGAR and reasonably requested by Purchaser, except for the
exhibits and schedules thereto and the documents incorporated therein by
reference. As of their respective dates, the SEC Documents complied in all
material respects with the requirements of the Exchange Act or the Securities
Act, as the case may be, 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. Any statements made
in any such SEC Documents that are or were required to be updated or amended
under applicable law have been so updated or amended. As of their respective
dates, the financial statements of the Company included in the SEC Documents
complied in all material respects with applicable accounting requirements and
the published rules and regulations of the SEC applicable with respect thereto.
Such financial statements have been prepared in accordance with United States
generally accepted accounting principles, consistently applied, during the
periods involved (except (i) as may be otherwise indicated in such financial
statements or the notes thereto, or (ii) in the case of unaudited interim
statements, to the extent they may not include footnotes or may be condensed or
summary statements) and fairly present in all material respects the
consolidated financial position of the Company and its subsidiaries as of the
dates thereof and the results of their operations and cash flows for the
periods then ended (subject, in the case of unaudited statements, to normal and
recurring year-end audit adjustments). Except as set forth in the SEC
Documents, the Company has no liabilities, contingent or otherwise, other than
(i) liabilities incurred in the ordinary course of business subsequent to the
date of such SEC Documents 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 SEC Documents, which
liabilities and obligations referred to in clauses (i) and (ii) of this
sentence would not individually or in the aggregate, have a Material Adverse
Effect.

         g.       Absence of Certain Changes. Except as disclosed in the SEC
Documents, since March 31, 2000, there has been no change or development which
individually or in the aggregate has had or could have a Material Adverse
Effect.

         h.       Absence of Litigation. Except as disclosed in the SEC
Documents and set forth on Schedule 4(h), there is no action, suit, proceeding,
inquiry or investigation before or by any




                                       7
<PAGE>   8


court, public board, government agency, self-regulatory organization or body
pending or, or to the knowledge of the Company, threatened against or affecting
the Company, or any of its subsidiaries, or any of their directors or officers
in their capacities as such, except as would not have a Material Adverse
Effect.

         i.       Intellectual Property. The Company and each of its
subsidiaries owns or is licensed to use all patents, patent applications,
trademarks, trademark applications, trade names, service marks, copyrights,
copyright applications, licenses, permits, 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") necessary for the conduct of its
business as now being conducted and as proposed to be conducted. Neither the
Company nor any of its subsidiaries is infringing or in conflict with any other
person with respect to any Intangibles. Neither the Company nor any of its
subsidiaries has received written notice that it is infringing upon third party
Intangibles. Neither the Company nor any of its subsidiaries has entered into
any consent, indemnification, forbearance to sue or settlement agreements with
respect to the validity of the Company's or such subsidiary's ownership or
right to use its Intangibles and, to the knowledge of the Company, there is no
basis for any such claim to be successful. The Intangibles are valid and
enforceable, and no registration relating thereto has lapsed, expired or been
abandoned or canceled or is the subject of cancellation or other adversarial
proceedings, and all applications therefor are pending and in good standing.
The Company has complied, in all material respects, with its contractual
obligations relating to the protection of the Intangibles used pursuant to
licenses. To the Company's knowledge, no person is infringing on or violating
the Intangibles owned or used by the Company.

         j.       Agreements. Except for the transactions contemplated by the
Purchase Agreement and except as filed as Exhibits to the SEC Documents or as
set forth in Schedule 4(j), there are no agreements, understandings,
instruments, contracts, proposed transactions, judgments, orders, writs or
decrees to which the Company or any of its subsidiaries is a party or by which
it is bound that may involve (i) obligations (contingent or otherwise) of, or
payments to, the Company in excess of $250,000 (other than licenses pursuant to
license agreements entered into in the ordinary course of the Company's
business) or (ii) the license of any patent, copyright, trade secret or other
proprietary right to or from the Company (other than licenses pursuant to
license agreements entered into in the ordinary course of the Company's
business), or (iii) provisions restricting or affecting the development,
manufacture or distribution of the Company's or its subsidiaries' products or
services, or (iv) indemnification by the Company or any subsidiary with respect
to infringements of proprietary rights (other than indemnification obligations
arising from purchase or sale agreements entered into in the ordinary course of
business) or (v) transactions between the Company and any of the Company's or
its subsidiaries' officers, directors, affiliates, or any affiliates thereof
(other than pursuant to employment agreements or stock or benefit plans), or
(vi) employment of the Company's officers or (vii) incurrence of any
indebtedness for money borrowed or any other liabilities (other than with
respect to dividend obligations, distributions, indebtedness and other
obligations incurred in the ordinary course of business or as disclosed in the
SEC Documents) individually in excess of $250,000 or, in the case of
indebtedness and/or liabilities individually less than $250,000, in excess of
$500,000 in the aggregate, or (viii) the making of any loans or advances to any
person,


                                       8
<PAGE>   9




other than ordinary advances for travel expenses, or (ix) the sale, exchange or
other disposition of any of its assets or rights, other than licenses in the
ordinary course of business.

         k.       Foreign Corrupt Practices. Neither the Company, its
subsidiaries, or any director, officer, agent, employee or other person acting
on behalf of the Company or any of its subsidiaries has, in the course of such
person's actions for, or on behalf of, the Company, or any of its subsidiaries,
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 United States Foreign Corrupt Practices Act of 1977; or made any bribe,
rebate, payoff, influence payment, kickback or other unlawful payment to any
foreign or domestic government official or employee.

         l.       Environment. Except as disclosed in the SEC Documents (i)
there is no environmental liability, nor, to the knowledge of the Company,
factors likely to give rise to any environmental liability, affecting any of
the properties of the Company or any of its subsidiaries that, individually or
in the aggregate, would have a Material Adverse Effect and (ii) neither the
Company nor any of the subsidiaries has violated any environmental law
applicable to it now or previously in effect, other than such violations or
infringements that, individually or in the aggregate, have not had and will not
have a Material Adverse Effect.

         m.       Title. The Company does not own any real property. Any real
property and facilities held under lease by the Company or any of its
subsidiaries are held by the Company or such subsidiary under valid, subsisting
and enforceable leases with such exceptions which have not had and will not
have a Material Adverse Effect.

         n.       Insurance. The Company and its subsidiaries maintain such
insurance relating to their business, operations, assets, key-employees and
officers and directors as is appropriate to their business, assets and
operations, in such amounts and against such risks as are customarily carried
and insured against by owners of comparable businesses, assets and operations,
and such insurance coverages will be continued in full force and effect to and
including the Closing Date other than those insurance coverages in respect of
which the failure to continue in full force and effect could not reasonably be
expected to have a Material Adverse Effect.

         o.       Disclosure. All information relating to or concerning the
Company and its subsidiaries set forth in this Agreement or provided to the
Purchaser in writing in connection with the transactions contemplated hereby is
true and correct in all material respects and the Company has not omitted to
state any material fact necessary in order to make the statements made herein
or therein, in light of the circumstances under which they were made, not
misleading; provided, however, that this representation and warranty shall not
apply to any information contained within any of the foregoing related to
future events, or the projected future financial performance of the Company,
including any financial projections, or descriptions of potential strategic or

breach or threatened breach by the Company of the provisions of this Agreement,
that the Purchaser shall be entitled, in addition to all other available
