                                   ARTICLE II
                         REPRESENTATIONS AND WARRANTIES

       2.1    Representations and Warranties of the Company. The Company hereby
makes the following representations and warranties to the Purchasers:

              (a)    Organization and Qualification. The Company is a
corporation duly incorporated, validly existing and in good standing under the
laws of the State of New York, with the requisite corporate power and authority
to own and use its properties and assets and to carry on its business as
currently conducted. The Company has no subsidiaries other than as set forth in
Schedule 2.1(a) (collectively, the "Subsidiaries"). Each of the Subsidiaries is
an entity, duly



                                      -2-
<PAGE>   4


incorporated or otherwise organized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation or organization (as
applicable), with the requisite power and authority to own and use its
properties and assets and to carry on its business as currently conducted. Each
of the Company and the Subsidiaries is duly qualified to do business and is in
good standing as a foreign corporation or other entity in each jurisdiction in
which the nature of the business conducted or property owned by it makes such
qualification necessary, except where the failure to be so qualified or in good
standing, as the case may be, could not, individually or in the aggregate, (x)
adversely affect the legality, validity or enforceability of the Securities (as
defined below) or any of this Agreement, the Registration Rights Agreement, the
Transfer Agent Instructions or the Warrants (collectively, the "Transaction
Documents"), (y) have or result in a material adverse effect on the results of
operations, assets, prospects, or condition (financial or otherwise) of the
Company and the Subsidiaries, taken as a whole, or (z) adversely impair the
Company's ability to perform fully on a timely basis its obligations under any
of the Transaction Documents (any of (x), (y) or (z), a "Material Adverse
Effect").

              (b)    Authorization; Enforcement. The Company has the requisite
corporate power and authority to enter into and to consummate the transactions
contemplated by each of the Transaction Documents and otherwise to carry out its
obligations thereunder. The execution and delivery of each of the Transaction
Documents by the Company and the consummation by it of the transactions
contemplated thereby have been duly authorized by all necessary action on the
part of the Company and no further action is required by the Company. Each of
the Transaction Documents has been duly executed by the Company and, when
delivered in accordance with the terms hereof, will constitute the valid and
binding obligation of the Company enforceable against the Company in accordance
with its terms. Neither the Company nor any Subsidiary is in violation of any of
the provisions of its respective certificate or articles of incorporation,
by-laws or other organizational or charter documents.

              (c)    Capitalization. The number of authorized, issued and
outstanding capital stock of the Company is set forth in Schedule 2.1(c). Except
as disclosed in Schedule 2.1(c), the Company owns all of the capital stock of
each Subsidiary. No shares of Common Stock are entitled to preemptive or similar
rights, nor is any holder of the securities of the Company entitled to
preemptive or similar rights arising out of any agreement or understanding with
the Company or any Subsidiary by virtue of any of the Transaction Documents.
Except as a result of the purchase and sale of the Shares and the Warrants and
except as disclosed in Schedule 2.1(c), there are no outstanding options,
warrants, script rights to subscribe to, calls or commitments of any character
whatsoever relating to, or securities, rights or obligations convertible into or
exchangeable for, or giving any Person any right to subscribe for or acquire,
any shares of Common Stock, or contracts, commitments, understandings, or
arrangements by which the Company or any Subsidiary is or may become bound to
issue additional shares of Common Stock, or securities or rights convertible or
exchangeable into shares of Common Stock. Except as disclosed in Schedule
2.1(c), the issue and sale of the Shares, Warrants or Underlying Shares (as
hereinafter defined) will not obligate the Company to issue shares of Common
Stock or other securities to any Person other than the Purchaser and will not
result in a right of any holder of Company securities to adjust the exercise or
conversion or reset price under such securities.

              (d)    Issuance of the Securities. The Securities are duly
authorized and, when issued and paid for in accordance with the terms hereof and
the Warrants, shall have been duly and




                                      -3-

validly issued, fully paid and nonassessable, free and clear of all liens,
encumbrances and rights of first refusal of any kind (collectively, "Liens").
The Company has reserved a number of duly authorized shares of Common Stock for
issuance hereunder upon exercise of the Warrants that is not less than the sum
of (i) the Shares to be issued hereunder; (ii) the number of shares of Common
Stock issuable upon exercise of the Adjustable Warrants on the First Vesting
Date (as defined in the Adjustable Warrant), assuming for such purposes that, on
the First Vesting Date, (A) the Applicable Share Number (as defined in the
Adjustable Warrant) equals the entire number of Shares purchased hereunder and
(B) the Adjustment Price (as defined in the Adjustable Warrant) equals 50% of
the Per Share Market Value on the Trading Day immediately preceding the Closing
Date and (iii) the number of shares of Common Stock as are issuable upon
exercise in full of the Closing Warrants (the number of shares of Common Stock
contemplated in (i), (ii) and (iii), the "Initial Minimum"). The shares of
Common Stock issuable upon exercise of the Warrants are referred to herein as
the "Underlying Shares." The Shares, the Warrants and the Underlying Shares are
collectively referred to herein as, the "Securities."

              (e)    No Conflicts. The execution, delivery and performance of
the Transaction Documents by the Company and the consummation by the Company of
the transactions contemplated thereby do not and will not (i) conflict with or
violate any provision of the Company's or any Subsidiary's certificate or
articles of incorporation, bylaws or other charter documents (each as amended
through the date hereof), or (ii) subject to obtaining the Required Approvals
(as defined below), 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 (with
or without notice, lapse of time or both) of, any agreement, credit facility,
debt or other instrument (evidencing a Company or Subsidiary debt or otherwise)
or other understanding to which the Company or any Subsidiary is a party or by
which any property or asset of the Company or any Subsidiary is bound or
affected, or (iii) result in a violation of any law, rule, regulation, order,
judgment, injunction, decree or other restriction of any court or governmental
authority to which the Company or a Subsidiary is subject (including federal and
state securities laws and regulations), or by which any property or asset of the
Company or a Subsidiary is bound or affected; except in the case of each of
clauses (ii) and (iii), as could not, individually or in the aggregate, have or
result in a Material Adverse Effect. The business of the Company is not being
conducted in violation of any law, ordinance or regulation of any governmental
authority, except for violations which, individually or in the aggregate, could
not have or result in a Material Adverse Effect.

              (f)    Filings, Consents and Approvals. Neither the Company nor
any Subsidiary is required to obtain any consent, waiver, authorization or order
of, give any notice to, or make any filing or registration with, any court or
other federal, state, local or other governmental authority or other Person in
connection with the execution, delivery and performance by the Company of the
Transaction Documents, other than (i) the filings required pursuant to Section
3.10, (ii) the filing with the Securities and Exchange Commission (the
"Commission") of a registration statement meeting the requirements set forth in
the Registration Rights Agreement and covering the resale of the Shares and the
Underlying Shares by the Purchasers (the "Underlying Shares Registration
Statement"), (iii) the application(s) to the Nasdaq Smallcap Market ("NASDAQ")
for the listing of the Underlying Shares for trading on the NASDAQ (and with any
other national securities exchange or market on which the Common Stock is then
listed) in the time and manner required thereby, (iv) applicable Blue Sky
filings, and (v) in all other cases where the failure to obtain such




                                      -4-
<PAGE>   6


consent, waiver, authorization or order, or to give such notice or make such
filing or registration could not have or result in, individually or in the
aggregate, a Material Adverse Effect (collectively, the "Required Approvals").

              (g)    Litigation; Proceedings. There is no action, suit, inquiry,
notice of violation, proceeding or investigation pending or, to the knowledge of
the Company, threatened against or affecting the Company or any of its
Subsidiaries or any of their respective properties before or by any court,
arbitrator, governmental or administrative agency or regulatory authority
(federal, state, county, local or foreign) (collectively, an "Action") which (i)
adversely affects or challenges the legality, validity or enforceability of any
of the Transaction Documents or the Securities or (ii) could, if there were an
unfavorable decision, individually or in the aggregate, have or result in a
Material Adverse Effect. Neither the Company nor any Subsidiary, nor any
director or officer thereof, is or has been the subject of any Action involving
(A) a claim of violation of or liability under federal or state securities laws
or (B) a claim of breach of fiduciary duty; (iv) the Company does not have
pending before the Commission any request for confidential treatment of
information and the Company has no knowledge of any expected such request that
would be made prior to the Effectiveness Date (as defined in the Registration
Rights Agreement); and (v) there has not been, and to the best of the Company's
knowledge there is not pending or contemplated, any investigation by the
Commission involving the Company or any current or former director or officer of
the Company.

              (h)    No Default or Violation. Neither the Company nor any
Subsidiary (i) is in default under or in violation of (and no event has occurred
which has not been waived which, with notice or lapse of time or both, would
result in a default by the Company or any Subsidiary under), nor has the Company

it is in violation of, any indenture, loan or credit agreement or any other
agreement or instrument to which it is a party or by which it or any of its
properties is bound, (ii) is in violation of any order of any court, arbitrator
or governmental body, or (iii) is in violation of any statute, rule or

result in a Material Adverse Effect.

              (i)    Private Offering. Assuming the accuracy of the
representations and warranties of the Purchasers set forth in Sections
2.2(b)-(g), the offer, issuance and sale of the Securities to the Purchasers as
contemplated hereby are exempt from the registration requirements of the
Securities Act of 1933, as amended (the "Securities Act"). Neither the Company
nor any Person acting on its behalf has taken or is, to the knowledge of the
Company, contemplating taking any action which could subject the offering,
issuance or sale of the Securities by the Company to the Purchasers hereunder to
the registration requirements of the Securities Act including soliciting any
offer to buy or sell the Securities by means of any form of general solicitation
or advertising.

              (j)    SEC Reports; Financial Statements. The Company has filed
all reports required to be filed by it under the Securities Exchange Act of
1934, as amended (the "Exchange Act"), including pursuant to Section 13(a) or
15(d) thereof, for the two years preceding the date hereof (or such shorter
period as the Company was required by law to file such material) (the foregoing
materials being collectively referred to herein as the "SEC Reports" and,
together with the Schedules to this Agreement, the "Disclosure Materials") on a
timely basis or has received a valid extension of such time of filing and has
filed any such SEC Reports prior to the expiration of any



                                      -5-
<PAGE>   7


such extension. As of their respective dates, the SEC Reports complied in all
material respects with the requirements of the Securities Act and the Exchange
Act and the rules and regulations of the Commission promulgated thereunder, and
none of the SEC Reports, when filed, 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. All material
agreements to which the Company is a party or to which the property or assets of
the Company are subject have been filed as exhibits to the SEC Reports as
required under the Exchange Act. The financial statements of the Company
included in the SEC Reports comply in all material respects with applicable
accounting requirements and the rules and regulations of the Commission with
respect thereto as in effect at the time of filing. Such financial statements
have been prepared in accordance with generally accepted accounting principles
applied on a consistent basis during the periods involved ("GAAP"), except as
may be otherwise specified in such financial statements or the notes thereto,
and fairly present in all material respects the financial position of the
Company and its consolidated subsidiaries as of and for the dates thereof and
the results of operations and cash flows for the periods then ended, subject, in
the case of unaudited statements, to normal, immaterial, year-end audit
adjustments. Since March 31, 2000, except as specifically disclosed in the SEC
Reports, (a) there has been no event, occurrence or development that has or that
could result in a Material Adverse Effect, (b) the Company has not incurred any
liabilities (contingent or otherwise) other than (x) liabilities incurred in the
ordinary course of business consistent with past practice and (y) liabilities
not required to be reflected in the Company's financial statements pursuant to
GAAP or required to be disclosed in filings made with the Commission, (c) the
Company has not altered its method of accounting or the identity of its auditors
and (d) the Company has not declared or made any payment or distribution of cash
or other property to its stockholders or officers or directors (other than in
compliance with existing Company stock option plans) with respect to its capital
stock, or purchased, redeemed (or made any agreements to purchase or redeem) any
shares of its capital stock.

              (k)    Investment Company. The Company is not, and is not an
Affiliate (as defined in Rule 405 under the Securities Act) of, an "investment
company" within the meaning of the Investment Company Act of 1940, as amended.

              (l)    Certain Fees. Except for certain fees payable to Wharton
Capital Partners, Ltd. and Wharton Capital Markets, LLC, no fees or commissions
will be payable by the Company to any broker, financial advisor or consultant,
finder, placement agent, investment banker, bank or other Person with respect to
the transactions contemplated by this Agreement. The Purchasers shall have no
obligation with respect to any fees or with respect to any claims made by or on
behalf of other Persons for fees of a type contemplated in this Section that may
be due in connection with the transactions contemplated by this Agreement. The
Company shall indemnify and hold harmless the Purchasers, their employees,
officers, directors, agents, and partners, and their respective Affiliates, from
and against all claims, losses, damages, costs (including the costs of
preparation and attorney's fees) and expenses suffered in respect of any such
claimed or existing fees, as such fees and expenses are incurred.

              (m)    Solicitation Materials. Neither the Company nor any Person
acting on the Company's behalf has solicited any offer to buy or sell the
Securities by means of any form of general solicitation or advertising.



                                      -6-
<PAGE>   8


              (n)    Form S-3 Eligibility. The Company is eligible to register
its Common Stock for resale under Form S-3 promulgated under the Securities Act.

              (o)    Listing and Maintenance Requirements. Except as set forth
in the SEC Reports, the Company has not, in the two years preceding the date
hereof received notice (written or oral) from the NASDAQ, any stock exchange,
market or trading facility on which the Common Stock is or has been listed (or
on which it has been quoted) to the effect that the Company is not in compliance
with the listing or maintenance requirements of such exchange, market or trading
facility. The Company is, and has no reason to believe that it will not in the
foreseeable future continue to be, in compliance with all such listing and
maintenance requirements.

              (p)    Patents and Trademarks. The Company and its Subsidiaries
have, or have rights to use, all patents, patent applications, trademarks,
trademark applications, service marks, trade names, copyrights, licenses and
rights which are necessary or material for use in connection with their
respective businesses as described in the SEC Reports and which the failure to
so have would have a Material Adverse Effect (collectively, the "Intellectual
Property Rights"). Neither the Company nor any Subsidiary has received a written
notice that the Intellectual Property Rights used by the Company or its
Subsidiaries violates or infringes upon the rights of any Person. To the best
knowledge of the Company, all such Intellectual Property Rights are enforceable
and there is no existing infringement by another Person of any of the
Intellectual Property Rights.

              (q)    Registration Rights; Rights of Participation. Except as set
forth on Schedule 6(b) to the Registration Rights Agreement, the Company has not
granted or agreed to grant to any Person any rights (including "piggy-back"
registration rights) to have any securities of the Company registered with the
Commission or any other governmental authority which has not been satisfied.
Except as set forth on Schedule 6(b) to the Registration Rights Agreement, no
Person has any right of first refusal, preemptive right, right of participation,
or any similar right to participate in the transactions contemplated by the
Transaction Documents.

              (r)    Regulatory Permits. 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 as described in the SEC Reports, except where the failure
to possess such permits could not, individually or in the aggregate, have or
result in a Material Adverse Effect ("Material Permits"), and neither the
Company nor any such Subsidiary has received any notice of proceedings relating
to the revocation or modification of any Material Permit.

              (s)    Title. Except as set forth on Schedule 2.1(s), the Company
and the Subsidiaries have good and marketable title in fee simple to all real
property owned by them which is material to the business of the Company and its
Subsidiaries and good and marketable title in all personal property owned by
them which is material to the business of the Company and its Subsidiaries, in
each case free and clear of all Liens, except for Liens as do not materially
affect the value of such property and do not interfere with the use made and
proposed to be made of such property by the Company and its Subsidiaries. Any
real property and facilities held under lease by the Company and its
Subsidiaries are held by them under valid, subsisting and enforceable leases of
which the Company and its Subsidiaries are in compliance and do not interfere
with the use made



                                      -7-
<PAGE>   9


and proposed to be made of such property and buildings by the Company and its
Subsidiaries.

              (t)    Labor Relations. No material labor problem exists or, to
the knowledge of the Company, is imminent with respect to any of the employees
of the Company.

              (u)    Disclosure. The Company confirms that neither it nor any
other Person acting on its behalf has provided any of the Purchasers or its
agents or counsel with any information that constitutes or might constitute
material non-public information. The Company understands and confirms that the
Purchasers shall be relying on the foregoing representations in effecting
transactions in securities of the Company. All disclosure provided to the
Purchasers regarding the Company, its business and the transactions contemplated
hereby, including the Schedules to this Agreement, furnished by or on behalf of
the Company are true and correct and do not contain any untrue statement of a
material fact or omit to state any material fact necessary in order to make the
statements made therein, in light of the circumstances under which they were
made, not misleading.

              (v)    Shareholders Rights Plan. Neither the consummation of the
transactions contemplated hereby nor the issuance of the Underlying Shares will
cause the Purchasers to be deemed an "Acquiring Person" under the Company's
shareholders rights plan.

              (w)    No Prior Registration Statement. The Company covenants that
it will not file a registration statement to register the securities of any
Person prior to the date on which the Company files a registration statement
covering the Registrable Securities. The restriction contained in this Section
21.(w) shall not affect the provisions of Section 3.9(a).

       2.2    Representations and Warranties of the Purchasers. Each Purchaser
hereby for itself and for no other Purchaser, represents and warrants to the
Company as follows:

              (a)    Organization; Authority. Such Purchaser is an entity duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization with the requisite corporate or partnership
power and authority to enter into and to consummate the transactions
contemplated by the Transaction Documents and otherwise to carry out its
obligations thereunder. The purchase by such Purchaser of the Securities
hereunder has been duly authorized by all necessary action on the part of such
Purchaser. Each of this Agreement and the Registration Rights Agreement has been
duly executed by such Purchaser, and when delivered by such Purchaser in
accordance with the terms hereof, will constitute the valid and legally binding
obligation of such Purchaser, enforceable against it in accordance with its
terms.

              (b)    Investment Intent. Such Purchaser is acquiring the
Securities as principal for its own account for investment purposes only and not
with a view to or for distributing or reselling such Securities or any part
thereof, without prejudice, however, to such Purchaser's right, subject to the
provisions of this Agreement, the Registration Rights Agreement and the
Warrants, at all times to sell or otherwise dispose of all or any part of such
Securities pursuant to an effective registration statement under the Securities
Act or under an exemption from such registration and in compliance with
applicable federal and state securities laws. Nothing contained herein shall be
deemed a representation or warranty by such Purchaser to hold Securities for any
period of time. Such Purchaser is acquiring the Securities hereunder in the
ordinary course of its business. Such

Purchaser does not have any agreement or understanding, directly or indirectly,
with any Person to distribute the Securities.

              (c)    Purchaser Status. At the time such Purchaser was offered
the Securities, it was, and at the date hereof it is, and at each exercise date
under its respective Warrants, it will be, an "accredited investor" as defined
in Rule 501(a) under the Securities Act.

              (d)    Experience of such Purchaser. Such Purchaser, either alone
or together with its representatives, has such knowledge, sophistication and
experience in business and financial matters so as to be capable of evaluating
the merits and risks of the prospective investment in the Securities, and has so
evaluated the merits and risks of such investment.

              (e)    Ability of such Purchaser to Bear Risk of Investment. Such
Purchaser is able to bear the economic risk of an investment in the Securities
and, at the present time, is able to afford a complete loss of such investment.

              (f)    Access to Information. Such Purchaser acknowledges that it
has reviewed the Disclosure Materials and has been afforded (i) the opportunity
to ask such questions as it has deemed necessary of, and to receive answers

Securities; (ii) access to information about the Company and the Company's
financial condition, results of operations, business, properties, management and
prospects sufficient to enable it to evaluate its investment; and (iii) the
opportunity to obtain such additional information which the Company possesses or
can acquire without unreasonable effort or expense that is necessary to make an
informed investment decision with respect to the investment and to verify the
accuracy and completeness of the information contained in the Disclosure
Materials. Neither such inquiries nor any other investigation conducted by or on
behalf of such Purchaser or its representatives or counsel shall modify, amend
or affect such Purchaser's right to rely on the truth, accuracy and completeness
of the Disclosure Materials and the Company's representations and warranties
contained in the Transaction Documents.

              (g)    General Solicitation. Such Purchaser is not purchasing the

              (h)    Reliance. Such Purchaser understands and acknowledges that
(i) the Securities are being offered and sold to it without registration under
the Securities Act in a private placement that is exempt from the registration
provisions of the Securities Act and (ii) the availability of such exemption,
depends in part on, and the Company will rely upon the accuracy and truthfulness
of, the representations set forth in Section 2.2(b)-(g) and such Purchaser
hereby consents to such reliance.

              The Company acknowledges and agrees that no Purchaser makes or has

                                   ARTICLE III
                         OTHER AGREEMENTS OF THE PARTIES

       3.1    Transfer Restrictions. (a) Securities may only be disposed of
pursuant to an effective registration statement under the Securities Act, to the
Company or pursuant to an available exemption from or in a transaction not
subject to the registration requirements of the Securities Act, and in
compliance with any applicable federal and state securities laws. In connection
with any transfer of Securities other than pursuant to an effective registration
statement or to the Company, except as otherwise set forth herein, the Company
may require the transferor thereof to provide to the Company an opinion of
counsel selected by the transferor, the form and substance of which opinion
shall be reasonably satisfactory to the Company, to the effect that such
transfer does not require registration of such transferred Securities under the
Securities Act. Any such transferee shall agree in writing to be bound by the
terms of this Agreement and shall have the rights of a Purchaser under this
Agreement and the Registration Rights Agreement.

              (b)    The Purchasers agree to the imprinting, so long as is
required by this Section 3.1(b), of the following legend on the Securities:

              THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND
       EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE
       UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS
       AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR
       SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
       SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A
       TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
       SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS
       EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT,
       THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY.

              Neither the Shares nor the Underlying Shares shall contain the
legend set forth above nor any other legend while an Underlying Shares
Registration Statement is effective under the Securities Act or the holder is
relying on paragraph (k) of Rule 144 promulgated under the Securities Act ("Rule
144") in connection with the resale of such Underlying Shares, or in the event
there is not an effective Underlying Shares Registration Statement and paragraph
(k) of Rule 144 is not then available for resale of the Underlying Shares, at
such time, as such legend is not required under applicable requirements of the
Securities Act (including judicial interpretations and pronouncements issued by
the staff of the Commission). Accordingly, the Shares issuable pursuant to
Section 1.1(a)(iii) shall be issued free of all legends and the Company shall
exchange the Shares issued at the Closing with Shares free of all legends within
four Trading Days of the Effective Date (as defined below). The Company shall
cause its counsel to issue the legal opinion included in the Transfer Agent
Instructions to the Company's transfer agent on the date that an Underlying
Shares Registration Statement is declared effective by the Commission (such
date, the "Effective Date"). The Company agrees that following the Effective
Date, it will, no later than three (3) Trading Days following the delivery by a
Purchaser to the Company of a certificate or certificates representing Shares or
Underlying Shares issued with a restrictive legend, deliver to such Purchaser
certificates



                                      -10-
<PAGE>   12


representing such Shares which shall be free from all restrictive and other
legends. The Company may not make any notation on its records or give
instructions to any transfer agent of the Company which enlarge the restrictions
of transfer set forth in this Section.

       3.2    Acknowledgment of Dilution. The Company acknowledges that the
issuance of Underlying Shares upon exercise of the Warrants will result in
dilution of the outstanding shares of Common Stock, which dilution may be
substantial under certain market conditions. The Company further acknowledges
that its obligation to issue Underlying Shares upon exercise of the Warrants
pursuant to the terms thereof is unconditional and absolute, subject to the
limitations set forth in the Warrants, regardless of the effect of any such
dilution.

       3.3    Furnishing of Information. As long as the Purchasers own
Securities, 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. As long as the Purchasers own Securities, if
the Company is not required to file reports pursuant to such sections, it will
prepare and furnish to the Purchasers and make publicly available in accordance
with Rule 144(c) promulgated under the Securities Act such information as is
required for the Purchasers to sell the Securities under Rule 144 promulgated
under the Securities Act. The Company further covenants that it will take such
further action as any holder of Securities may reasonably request, all to the
extent required from time to time to enable such Person to sell Underlying
Shares without registration under the Securities Act within the limitation of
the exemptions provided by Rule 144 promulgated under the Securities Act,
including causing its attorneys to render and deliver any legal opinion required
in order to permit a Purchaser to receive Underlying Shares free of all
restrictive legends and to subsequently sell Underlying Shares under Rule 144
upon receipt of a notice of an intention to sell or other form of notice having
a similar effect. Upon the request of any such Person, the Company shall deliver
to such Person a written certification of a duly authorized officer as to
whether it has complied with such requirements.

       3.4    Integration. The Company shall not, and shall use its best efforts
to ensure that, no Affiliate of the Company shall, sell, offer for sale or
solicit offers to buy or otherwise negotiate in respect of any security (as
defined in Section 2 of the Securities Act) that would be integrated with the
offer or sale of the Securities in a manner that would require the registration
under the Securities Act of the sale of the Securities to the Purchasers, or
that would be integrated with the offer or sale of the Securities for the
purposes of the rules and regulations of NASDAQ.

       3.5    Increase in Authorized Shares. If on any date the Company would
be, if a notice of exercise were to be delivered on such date, precluded from
issuing the sum of (i) 200% of the number of Underlying Shares then issuable
upon exercise in full of the Adjustable Warrants and (ii) the number of
Underlying Shares issuable upon exercise in full of the Closing Warrants (the
"Current Required Minimum") due to the unavailability of a sufficient number of
authorized but unissued or reserved shares of Common Stock, then the Board of
Directors of the Company shall promptly (and in any case, within 30 Business
Days from such date) prepare and mail to the stockholders of the Company proxy
materials requesting authorization to amend the Company's certificate or
articles of incorporation to increase the number of shares of Common Stock which
the Company is authorized to issue to at least such number of shares as
reasonably requested by the Purchasers in order to provide for such number of
authorized and unissued shares of Common Stock to enable the Company to comply
with its issuance, exercise and reservation of shares obligations



                                      -11-
<PAGE>   13


as set forth in this Agreement and the Warrants (the sum of (x) the number of
shares of Common Stock then outstanding plus all shares of Common Stock issuable
upon exercise of all outstanding options, warrants and convertible instruments
other than the Warrants and (y) the Current Required Minimum, shall be a
reasonable number). In connection therewith, the Board of Directors shall (a)
adopt proper resolutions authorizing such increase, (b) recommend to and
otherwise use its best efforts to promptly and duly obtain stockholder approval
to carry out such resolutions (and hold a special meeting of the stockholders no
later than the earlier to occur of the 60th day after delivery of the proxy
materials relating to such meeting and the 90th day after request by a holder of
Warrants to issue the number of Underlying Shares in accordance with the terms
hereof) and (c) within five Business Days of obtaining such stockholder
authorization, file an appropriate amendment to the Company's certificate or
articles of incorporation to evidence such increase.

       3.6    Reservation and Listing of Underlying Shares. (a) The Company
shall (i) in the time and manner required by NASDAQ and such other exchange,
market or quotation facility on which the Common Stock is traded, prepare and
file with NASDAQ (and such national securities exchange, market or trading or
quotation facility on which the Common Stock is then traded) an additional
shares listing application covering a number of shares of Common Stock which is
not less than the Initial Minimum, (ii) take all steps necessary to cause such
shares of Common Stock to be approved for listing on the NASDAQ (as well as on
any such other national securities exchange or market or trading or quotation
facility on which the Common Stock is then listed) as soon as possible
thereafter, and (iii) provide to the Purchasers evidence of such listing, and
the Company shall maintain the listing of its Common Stock thereon. If the
number of Underlying Shares issuable upon exercise of the then unexercised
portion of the Warrants exceeds 85% of the number of Underlying Shares
previously listed on account thereof with NASDAQ (and any such other required
exchanges), then the Company shall take the necessary actions to immediately
list a number of Underlying Shares as equals no less than the then Current
Required Minimum.

              (b)    The Company shall maintain a reserve of shares of Common
Stock for issuance upon exercise in full of the Warrants in accordance with this
Agreement and the Warrants, respectively, in such amount as may be required to
fulfill its obligations in full under the Transaction Documents, which reserve
shall equal no less than the then Current Required Minimum.

       3.7    Exercise Procedures. The Transfer Agent Instructions and Form of
Election to Purchase under the Warrants set forth the totality of the procedures
with respect to the exercise of the Warrants, including the form of legal
opinion, if necessary, that shall be rendered to the Company's transfer agent
and such other information and instructions as may be reasonably necessary to
enable the Purchasers to exercise their Warrants.

       3.8    Exercise Obligations. The Company shall honor exercises of the
Warrants and shall deliver Underlying Shares in accordance with the terms,
conditions and time periods set forth in the Warrants.

       3.9    Limitation on Registration.

              (a)    Except for (x) Underlying Shares, (y) other "Registrable
Securities" (as such term is defined in the Registration Rights Agreement) to be
registered, and securities of the Company permitted pursuant to Section 6(c) of
the Registration Rights Agreement to be registered,




                                      -12-
<PAGE>   14


in the Underlying Shares Registration Statement in accordance with the
Registration Rights Agreement, and (z) Common Stock permitted to be issued
pursuant to Section 3.9 (b), the Company shall not, until the 120th calendar day
after the Effective Date, without the prior written consent of the Purchasers
(i) issue or sell any of its or any of its Affiliates' equity or
equity-equivalent securities pursuant to Regulation S promulgated under the
Securities Act, or (ii) register any securities of the Company. Any days after
the Effective Date that a Purchaser is unable to sell Underlying Shares under
the Underlying Shares Registration Statement shall be added to such 120 calendar
day period.

              (b)    The Company may engage in (i) the granting of options or
warrants to employees, officers, consultants and directors of the Company, and
the issuance of Common Stock upon exercise of such options or warrants granted
under any stock option plan heretofore or hereinafter duly adopted by the
Company and (ii) issuances of Common Stock pursuant to a Strategic Transaction
(as defined herein). A "Strategic Transaction" shall mean a transaction or
relationship in which the Company issues shares of Common Stock to a Person
which is, itself or through its subsidiaries, an operating company in a business
related to the business of the Company and in which the Company receives
material benefits in addition to the investment of funds, but shall not include
a transaction in which the Company is issuing securities primarily for the
purpose of raising capital or to an entity whose primary business is investing
in securities.

       3.10   Certain Securities Laws Disclosures; Publicity. The Company shall:
(i) on the Closing Date issue a press release reasonably acceptable to the
Purchasers disclosing the transactions contemplated hereby, (ii) file with the
Commission a Report on Form 8-K disclosing the transactions contemplated hereby
within ten Business Days after the Closing Date, and (iii) timely file with the
Commission a Form D promulgated under the Securities Act. The Company shall, no
less than two Business Days prior to the filing of any disclosure required by
clauses (ii) and (iii) above, provide a copy thereof to the Purchasers for their
review. The Company and the Purchasers shall consult with each other in issuing
any other press releases or otherwise making public statements or filings and
other communications with the Commission or any regulatory agency or stock
market or trading facility with respect to the transactions contemplated hereby
and neither party shall issue any such press release or otherwise make any such
public statement, filings or other communications without the prior written
consent of the other, except if such disclosure is required by law or stock
market regulation, in which such case the disclosing party shall promptly
provide the other party with prior notice of such public statement, filing or
other communication. Notwithstanding the foregoing, the Company shall not
publicly disclose the names of the Purchasers, or include the names of the
Purchasers in any filing with the Commission, or any regulatory agency, trading
facility or stock market without the prior written consent of the Purchasers,
except to the extent such disclosure (but not any disclosure as to the
controlling Persons thereof) is required by law or stock market regulations, in
which case the Company shall provide the Purchasers with prior notice of such
disclosure.

       3.11   Use of Proceeds. The Company shall use the net proceeds from the
sale of the Securities hereunder for working capital purposes and not for the
satisfaction of any portion of the Company's debt (other than payment of trade
payables in the ordinary course of the Company's business and prior practices),
to redeem any Company equity or equity-equivalent securities or to settle any
outstanding litigation.

       3.12   Shareholders Rights Plan No claim will be made or enforced by the
Company or any other Person that any Purchaser is an "Acquiring Person" under
any shareholders rights plan or similar arrangement or in any way could be
deemed to trigger the provisions of such plan by virtue of receiving Securities
under the Transaction Documents.

       3.13   Reimbursement. If any Purchaser becomes involved in any capacity
in any action, proceeding or investigation brought by or against any Person,
including stockholders of the Company, solely as a result of acquiring the
Securities under this Agreement and the Warrants, the Company will reimburse
such Purchaser for its reasonable legal and other expenses (including the cost
of any investigation preparation and travel in connection therewith) incurred in
connection therewith, as such expenses are incurred. The reimbursement
obligations of the Company under this paragraph shall be in addition to any
liability which the Company may otherwise have, shall extend upon the same terms
and conditions to any Affiliates of the Purchasers who are actually named in
such action, proceeding or investigation, and partners, directors, agents,
employees and controlling persons (if any), as the case may be, of the
Purchasers and any such Affiliate, and shall be binding upon and inure to the
benefit of any successors, assigns, heirs and personal representatives of the
Company, the Purchasers and any such Affiliate and any such Person. The Company
also agrees that neither the Purchasers nor any such Affiliates, partners,
directors, agents, employees or controlling persons shall have any liability to
the Company or any Person asserting claims on behalf of or in right of the
Company solely as a result of acquiring the Securities under this Agreement and
the Warrants.

"Event Notice ") requiring the Company to reacquire all or a portion of the
Shares which the Purchasers acquired hereunder at the put price ("Put Price")

related transactions, (iii) the merger of the Company with or into another
entity, consolidation or sale of all or substantially all of the assets of the
Company in one or a series of related transactions, unless following such
transaction or series of transactions, the holders of the Company's securities
prior to the first such transaction continue to hold at least 2/3 of the
securities of the surviving entity or acquirer of such assets or (iv) the
execution by the Company of an agreement to which the Company is a party or by
which it is bound, providing for any of the events set forth above in (i), (ii)

the Holder to be able to participate in such transaction), it being agreed that

Commission;

trading on the Nasdaq or a Subsequent Market or for an aggregate of five or more
consecutive Trading Days;

                     (f)    The daily trading volume of the Common Stock on the

       4.10   Execution. This Agreement may be executed in two or more
counterparts, all of which when taken together shall be considered one and the
same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party, it being understood that both
parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission, such signature shall create a valid and
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
page were an original thereof.

       4.11   Severability. In case any one or more of the provisions of this
Agreement shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Agreement shall not
in any way be affecting or impaired thereby and the parties will attempt to
agree upon a valid and enforceable provision which shall be a reasonable
substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement.

       4.12   Remedies. In addition to being entitled to exercise all rights
provided herein or granted by law, including recovery of damages, each of the
Purchasers and the Company will be entitled to specific performance of the each
others obligations under the Transaction Documents. The parties agree that
monetary damages may not be adequate compensation for any loss incurred by
reason of any breach of obligations described in the foregoing sentence and
hereby agrees to waive in any action for specific performance of any such
obligation the defense that a remedy at law would be adequate.

       4.13   Independent Nature of Purchasers' Obligations and Rights. The
obligations of each Purchaser under any Transaction Document is several and not
joint with the obligations of any other Purchaser, and no Purchaser shall be
responsible in any way for the performance of the obligations of any other
Purchaser under any Transaction Document. Nothing contained herein or in any
Transaction Document, and no action taken by any Purchaser pursuant thereto,
shall be deemed to constitute the Purchasers as a partnership, an association, a
joint venture or any other kind of entity, or create a presumption that the
Purchasers are in any way acting in concert with respect to such obligations or
the transactions contemplated by the Transaction Document. Each Purchaser shall
be entitled to independently protect and enforce its rights, including without
limitation the rights arising out of this Agreement or out of the other
Transaction Documents, and it shall not be necessary for any other Purchaser to
be joined as an additional party in any proceeding for such purpose.
