         NOW THEREFORE, the Company and the Buyers hereby agree as follows:

preceding the Closing Date.

of each Buyer, stock certificates (in the denominations as such Buyer shall
request) (the "COMMON STOCK CERTIFICATES") representing such number of the
shares of Common Stock which such Buyer is then purchasing (as indicated
opposite such Buyer's name on Schedule 1). Upon the completion of the conditions
contained in Sections 6 and 7 of this Agreement, the Escrow Agent shall deliver
the certificates representing the shares of Common Stock to the Buyers via

For purposes of this Agreement "BUSINESS DAY" means any day in which the
Principal Market is open for business.

         2. BUYER'S REPRESENTATIONS AND WARRANTIES.

            Each Buyer represents and warrants with respect to only itself
that:

            a. Investment Purpose. Such Buyer is acquiring the Common Stock (the
Common Stock may also be referred to herein as the "SECURITIES"), for its own
account for investment only and not with a view towards, or for resale in
connection with, the public sale or distribution thereof, except pursuant to
sales registered or exempted under the 1933 Act; provided, however, that by
making the representations herein, such Buyer does not agree to hold any of the
Securities for any minimum or other specific term and reserves the right to
dispose of the Securities at any time in accordance with or pursuant to a
registration statement or an exemption under the 1933 Act.

            b. Accredited Investor Status. Such Buyer is an "accredited
investor" as that term is defined in Rule 501(a) of Regulation D.

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



                                       2
<PAGE>   3

determine the availability of such exemptions and the eligibility of such Buyer
to acquire such Securities.

            d. Information. Such Buyer and its advisors, if any, have been
furnished with all materials relating to the business, finances and operations
of the Company and materials relating to the offer and sale of the Securities
which have been requested by such Buyer. Such Buyer and its advisors, if any,
have been afforded the opportunity to ask questions of the Company. Neither such
inquiries nor any other due diligence investigations conducted by such Buyer or
its advisors, if any, or its representatives shall modify, amend or affect such
Buyer's right to rely on the Company's representations and warranties contained
in Section 3 below. Such Buyer understands that its investment in the Securities
involves a high degree of risk. Such Buyer has sought such accounting, legal and
tax advice as it has considered necessary to make an informed investment
decision with respect to its acquisition of the Securities.

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

            f. Transfer or Resale. Such Buyer understands that except as
provided in the Registration Rights Agreement: (i) the Securities have not been
and are not being registered under the 1933 Act or any state securities laws,
and may not be offered for sale, sold, assigned or transferred unless (A)
subsequently registered thereunder, (B) such Buyer shall have delivered to the
Company an opinion of counsel, in a generally acceptable form, to the effect
that such Securities to be sold, assigned or transferred may be sold, assigned
or transferred pursuant to an exemption from such registration, or (C) such
Buyer provides the Company with reasonable assurance that such Securities can be
sold, assigned or transferred pursuant to Rule 144 promulgated under the 1933
Act, as amended, (or a successor rule thereto) ("RULE 144"); and (ii) any sale
of the Securities made in reliance on Rule 144 may be made only in accordance
with the terms of Rule 144 and further, and if Seller intends to utilize Rule
144 but Rule 144 is not applicable to such resale, any resale of the Securities
under circumstances in which the Seller (or the person through whom the sale is
made) may be deemed to be an underwriter (as that term is defined in the 1933
Act) may require compliance with some other exemption under the 1933 Act or the
rules and regulations of the SEC thereunder.

            g. Legends. Such Buyer understands that the Common Stock
Certificates, until such time as the sale of the Common Stock has been
registered under the 1933 Act as contemplated by the Registration Rights
Agreement, shall bear a restrictive legend in substantially the following form
(and a stop-transfer order may be placed against transfer of such stock
certificates):

      THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS




                                       3
<PAGE>   4

      AMENDED (THE "1933 ACT"), OR APPLICABLE STATE SECURITIES LAWS. THE
      SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE OFFERED FOR
      SALE, SOLD, TRANSFERRED OR ASSIGNED (1) IN THE ABSENCE OF AN EFFECTIVE
      REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE 1933 ACT OR APPLICABLE
      STATE SECURITIES LAWS, OR (2) IN THE ABSENCE OF AN OPINION OF COUNSEL, IN
      A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER THE
      1933 ACT OR (3) UNLESS SOLD, TRANSFERRED OR ASSIGNED PURSUANT TO RULE 144
      UNDER SAID ACT.

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of the Securities upon which it is
stamped, if, unless otherwise required by state securities laws, (i) such
Securities are registered for sale under the 1933 Act, (ii) in connection with a
sale transaction, such holder provides the Company with an opinion of counsel,
in a generally acceptable form, to the effect that a public sale, assignment or
transfer of the Securities may be made without registration under the 1933 Act,
or (iii) such holder provides the Company with reasonable assurances that the
Securities can be sold pursuant to Rule 144.

            h. Validity; Enforcement. This Agreement has been duly and validly
authorized, executed and delivered on behalf of such Buyer and is a valid and
binding agreement of such Buyer enforceable against such Buyer in accordance
with its terms, subject as to enforceability to general principles of equity and
to applicable bankruptcy, insolvency, reorganization, moratorium, liquidation
and other similar laws relating to, or affecting generally, the enforcement of
applicable creditors' rights and remedies.

            i. Residency. Such Buyer is a resident of that country and state, if
applicable, specified in its address on Schedule 1.

3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

            The Company represents and warrants to each of the Buyers
that:

            a. Organization and Qualification. The Company and its
"SUBSIDIARIES" (which for purposes of this Agreement means any entity in which
the Company, directly or indirectly, owns a controlling position of capital
stock or holds a controlling position of an equity or similar interest) are
corporations duly organized and validly existing in good standing under the laws
of the jurisdiction in which they are incorporated, and have the requisite
corporate power and authorization to own their properties and to carry on their
business as now being conducted. Each of the Company and its Subsidiaries is
duly qualified as a foreign corporation to do business and is in good standing
in every jurisdiction in which its ownership of property or the nature of the
business conducted by it makes such qualification necessary, except to the
extent that the failure to be so qualified or be in good standing would not have
a Material Adverse Effect. As used in this Agreement, "MATERIAL ADVERSE EFFECT"
means any material adverse effect on the business,



                                       4
<PAGE>   5

properties, assets, operations, results or operations, financial condition or
prospects of the Company and its Subsidiaries, if any, taken as a whole, or on
the transactions contemplated hereby or by the agreements and instruments to be
entered into in connection herewith, or on the authority or ability of the
Company to perform its obligations under the Transaction Documents (as defined
below in Section 3(b)).

            b. Authorization; Enforcement; Validity. (i) The Company has the
requisite corporate power and authority to enter into and perform this
Agreement, the Registration Rights Agreement, the Transfer Agent Instructions
(as defined in Section 5) and each of the other agreements entered into by the
parties hereto in connection with the transactions contemplated by this
Agreement (collectively, the "TRANSACTION DOCUMENTS"), and to issue the
Securities in accordance with the terms hereof and thereof, (ii) the execution
and delivery of the Transaction Documents by the Company and the consummation by
it of the transactions contemplated hereby and thereby, including without
limitation the issuance of the Common Stock, have been duly authorized by the
Company's Board of Directors and no further consent or authorization is required
by the Company, its Board of Directors or its stockholders, (iii) the
Transaction Documents have been duly executed and delivered by the Company, and
(iv) the Transaction Documents constitute the valid and binding obligations of
the Company enforceable against the Company in accordance with their terms,
except as such enforceability may be limited by general principles of equity or
applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or
similar laws relating to, or affecting generally, the enforcement of creditors'
rights and remedies.

            c. Issuance of Securities. The Securities are duly authorized and,
upon issuance in accordance with the terms hereof, shall be (i) validly issued,
fully paid and non-assessable and (ii) free from all taxes, liens and charges
with respect to the issue thereof. Assuming the accuracy of Buyers'
representations and warranties set forth in Section 2 above, the issuance by the
Company of the Securities is exempt from registration under the 1933 Act.

            d. No Conflicts. The execution, delivery and performance of the
Transaction Documents by the Company and the consummation by the Company of the
transactions contemplated hereby and thereby (including, without limitation, the
Company's issuance of the Securities) will not (i) result in a violation of the
Company's Certificate of Incorporation, as amended and as in effect on the date
hereof (the "CERTIFICATE OF INCORPORATION") or the Company's By-laws, as amended
and as in effect on the date hereof (the "BY-LAWS") or any Certificate of
Designations, Preferences and Rights of any outstanding series of preferred
stock of the Company 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 material agreement, indenture or instrument to which the
Company or any of its Subsidiaries is a party, or result in a violation of any
law, rule, regulation, order, judgment or decree (including federal and state
securities laws and regulations and the rules and regulations of the Principal
Market (as defined in Section 4(f) below)) 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. Neither the Company nor its Subsidiaries is
in violation of any term of or in default under its Certificate of
Incorporation, any Certificate of Designations, Preferences and Rights of any
outstanding series of preferred stock of the Company or By-laws or their
organizational charter or by-laws, respectively. Neither the Company or any of
its Subsidiaries is in



                                       5
<PAGE>   6


violation or any term of or in default under any contract, agreement, mortgage,
indebtedness, indenture, instrument, judgment, decree or order or any statute,
rule or regulation applicable to the Company or its Subsidiaries, except for
possible conflicts, defaults, terminations, amendments which would not have a
Material Adverse Effect. The business of the Company and its Subsidiaries is not
being conducted, and shall not be conducted, in violation of any law, ordinance,
regulation of any governmental entity, except for possible violations the
sanctions for which either individually or in the aggregate would not have a
Material Adverse Effect. Except as specifically contemplated by the Transaction
Documents and as required under the 1933 Act, the Company is not required to
obtain any consent, authorization or order of, or make any filing or
registration with, any court or governmental agency or any regulatory or
self-regulatory agency in order for it to execute, deliver or perform any of its
obligations under or contemplated by the Transaction Documents in accordance
with the terms hereof or thereof. All consents, authorizations, orders, filings
and registrations which the Company is required to obtain prior to Closing
pursuant to the preceding sentence have been obtained or effected on or prior to
the date hereof. The Company and its Subsidiaries are unaware of any facts or
circumstances which might give rise to any of the foregoing. The Company is not
in violation of the listing requirements of the Principal Market (as defined in
Section 4(f) below).

            e. SEC Documents; Financial Statements. As of the Closing, the
Company has filed all reports, schedules, forms, statements and other documents
required to be filed by it with the SEC pursuant to the reporting requirements
of the Securities Exchange Act of 1934, as amended (the "1934 ACT") (all of the
foregoing filed prior to the date hereof and all exhibits included therein and
financial statements and schedules thereto and documents incorporated by
reference therein being hereinafter referred to as the "SEC DOCUMENTS"). As of
their respective dates, the SEC Documents complied in all material respects with
the requirements of the 1934 Act and the rules and regulations of the SEC
promulgated thereunder applicable to the SEC Documents, and none of the SEC
Documents, at the time they were filed with the SEC, contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading. As of their
respective dates, the financial statements of the Company included in the SEC
Documents complied as to form in all material respects with applicable
accounting requirements and the published rules and regulations of the SEC with
respect thereto. Such financial statements have been prepared in accordance with
generally accepted accounting principles, consistently applied, during the
periods involved (except (i) as may be otherwise indicated in such financial
statements or the notes thereto, or (ii) in the case of unaudited interim
statements, to the extent they may exclude footnotes or may be condensed or
summary statements) and fairly present in all material respects the financial
position of the Company as of the dates thereof and the results of its
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end audit adjustments). No other
information provided by or on behalf of the Company to the Buyers which is not
included in the SEC Documents, including, without limitation contains any untrue
statement of a material fact or



                                       6
<PAGE>   7

omits to state any material fact necessary in order to make the statements
therein, in the light of the circumstance under which they are or were made, not
misleading. Neither the Company nor any of its Subsidiaries or any of their
officers, directors, employees or agents have provided the Buyers with any
material, nonpublic information.

            f. Absence of Certain Changes. Since the most recent filing by
the Company with the SEC, there has been no material adverse change and no
material adverse development in the business, properties, operations, financial
condition, results of operations or prospects of the Company or its
Subsidiaries. The Company has not taken any steps, and does not currently expect
to take any steps, to seek protection pursuant to any bankruptcy law nor does
the Company or any of its Subsidiaries have any knowledge or reason to believe
that its creditors intend to initiate involuntary bankruptcy proceedings.

            g. Absence of Litigation. Except as set forth in the SEC Documents,
there is no action, suit, proceeding, inquiry or investigation before or by any
court, public board, government agency, self-regulatory organization or body
pending or, to the knowledge of the Company or any of its Subsidiaries,
threatened against or affecting the Company, the Company's common stock, the
Common Shares or any of the Company's Subsidiaries or any of the Company's or
the Company's Subsidiaries' officers or directors in their capacities as such.

            h. Acknowledgment Regarding Buyers' Purchase of Common Stock. The
Company acknowledges and agrees that each of the Buyers is acting solely in the
capacity of arm's length purchaser with respect to the Transaction Documents and
the transactions contemplated hereby and thereby. The Company further
acknowledges that each Buyer is not acting as a financial advisor or fiduciary
of the Company (or in any similar capacity) with respect to the Transaction
Documents and the transactions contemplated hereby and thereby and any advice
given by any of the Buyers or any of their respective representatives or agents
in connection with the Transaction Documents and the transactions contemplated
hereby and thereby is merely incidental to such Buyer's purchase of the
Securities. The Company further represents to each Buyer that the Company's
decision to enter into the Transaction Documents has been based solely on the
independent evaluation by the Company and its representatives.

            i. No Undisclosed Events, Liabilities, Developments or
Circumstances. No event, liability, development or circumstance has occurred or
exists, or is contemplated to occur, with respect to the Company or its
Subsidiaries or their respective business, properties, prospects, operations or
financial condition, that would be required to be disclosed by the Company under
applicable securities laws on a registration statement filed with the SEC
relating to an issuance and sale by the Company of its common stock and which
has not been publicly announced.

            j. No General Solicitation. Neither the Company, nor any of its
affiliates, nor any person acting on its or their behalf, has engaged in any
form of general solicitation or general advertising (within the meaning of
Regulation D under the 1933 Act) in connection with the offer or sale of the
Securities.



                                       7
<PAGE>   8


            k. 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 require registration of any of
the Securities under the 1933 Act or cause this offering of the Securities to be
integrated with prior offerings by the Company for purposes of the 1933 Act or
any applicable stockholder approval provisions, including, without limitation,
under the rules and regulations of any exchange or automated quotation system on
which any of the securities of the Company are listed or designated, nor will
the Company or any of its Subsidiaries take any action or steps that would
require registration of any of the Securities under the 1933 Act or cause the
offering of the Securities to be integrated with other offerings.

            l. Employee Relations. 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.


            m. Intellectual Property Rights. The Company and its Subsidiaries
own or possess adequate rights or licenses to use all trademarks, trade names,
service marks, service mark registrations, service names, patents, patent
rights, copyrights, inventions, licenses, approvals, governmental
authorizations, trade secrets and rights necessary to conduct their respective
businesses as now conducted. None of the Company's trademarks, trade names,
service marks, service mark registrations, service names, patents, patent
rights, copyrights, inventions, licenses, approvals, government authorizations,
trade secrets or other intellectual property rights have expired or terminated,
or are expected to expire or terminate within two years from the date of this
Agreement. The Company and its Subsidiaries do not have any knowledge of any
infringement by the Company or its Subsidiaries of trademark, trade name rights,
patents, patent rights, copyrights, inventions, licenses, service names, service
marks, service mark registrations, trade secret or other similar rights of
others, or of any such development of similar or identical trade secrets or
technical information by others and the Company and its Subsidiaries are unaware
of any facts or circumstances which might give rise to any of the foregoing. The
Company and its Subsidiaries have taken reasonable security measures to protect
the secrecy, confidentiality and value of all of their intellectual properties.

            n. Environmental Laws. The Company and its Subsidiaries (i) are in
compliance with any and all applicable foreign, federal, state and local laws
and regulations relating to the protection of human health and safety, the
environment or hazardous or toxic substances or wastes, pollutants or
contaminants ("ENVIRONMENTAL LAWS"), (ii) have received all permits, licenses or
other approvals required of them under applicable Environmental Laws to conduct
their respective businesses and (iii) are in compliance with all terms and
conditions of any such permit, license or approval.

            o. Title. The Company and its Subsidiaries have good and marketable
title in fee simple to all real property and good and marketable title to all
personal property owned by them which is material to the business of the Company
and its Subsidiaries, in each case free and clear of all liens, encumbrances and
defects except such as are described in the SEC Documents



                                       8
<PAGE>   9

or such 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 any of its Subsidiaries. Any real property and facilities held under
lease by the Company and any of its Subsidiaries are held by them under valid,
subsisting and enforceable leases with such exceptions as are not material and
do not interfere with the use made and proposed to be made of such property and
buildings by the Company and its Subsidiaries.

            p. Insurance. The Company and each of its Subsidiaries are insured
by insurers of recognized financial responsibility against such losses and risks
and in such amounts as management of the Company believes to be prudent and
customary in the businesses in which the Company and its Subsidiaries are
engaged and the Company does not have any reason to believe it will not be able
to renew its existing insurance coverage under substantially similar terms for
the next two (2) years.

            q. 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, and neither the Company nor any such Subsidiary has received any
notice of proceedings relating to the revocation or modification of any such
certificate, authorization or permit.

            r. Tax Status. The Company and each of its Subsidiaries has made or
filed all federal and state income and all other tax returns, reports and
declarations required by any jurisdiction to which it is subject (unless and
only to the extent that the Company and each of its Subsidiaries has set aside
on its books provisions reasonably adequate for the payment of all unpaid and
unreported taxes) and has paid all taxes and other governmental assessments and
charges that are material in amount, shown or determined to be due on such
returns, reports and declarations, except those being contested in good faith
and has set aside on its books provision reasonably adequate for the payment of
all taxes for periods subsequent to the periods to which such returns, reports
or declarations apply. There are no unpaid taxes in any material amount claimed
to be due by the taxing authority of any jurisdiction, and the officers of the
Company know of no basis for any such claim.

            s. Transactions With Affiliates. Except as set forth in the SEC
Documents filed at least ten days prior to the date hereof, none of the
officers, control parties, control entities, directors, or employees of the
Company is presently a party to any transaction with the Company or any of its
Subsidiaries (other than for services as employees, officers and directors),
including any contract, agreement or other arrangement providing for the
furnishing of services to or by, providing for rental of real or personal
property to or from, or otherwise requiring payments to or from any officer,
director or such employee or, to the knowledge of the Company, any corporation,
partnership, trust or other entity in which any officer, director, or any such
employee has a substantial interest or is an officer, director, trustee or
partner.

            t. Eligibility. The Company is currently eligible to register the
resale of the Common Stock on a registration statement on Form SB-2 under the
1933 Act.




                                       9
<PAGE>   10

            u. Dilutive Effect. The Company understands and acknowledges that
additional Common Stock may be issuable in certain circumstances. The Company
further acknowledges that its obligation to issue the Common Stock being
purchased hereunder and any additional Common Stock issuable pursuant to the
terms of the Transaction Documents is absolute and unconditional regardless of
the dilutive effect that such issuance may have on the ownership interests of
other stockholders of the Company.

         4. COVENANTS.

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

            b. Form D and Blue Sky. The Company agrees to file a Form D
with respect to the Securities as required under Regulation D and to provide a
copy thereof to each Buyer promptly after such filing. The Company shall, on or
before the Closing Date, take such action as the Company shall reasonably
determine is necessary in order to obtain an exemption for or to qualify the
Securities for sale to the Buyers at the Closing pursuant to this Agreement
under applicable securities or "Blue Sky" laws of the states of the United
States, and shall provide evidence of any such action so taken to the Buyers on
or prior to the Closing Date. The Company shall make all filings and reports
relating the offer and sale of the Securities required under applicable
securities or "Blue Sky" laws of the states of the United States following the
Closing Date.

            c. Reporting Status. Until the earlier of (i) the date which is one
year after the date as of which the Investors (as that term is defined in the
Registration Rights Agreement) may sell all of the Common Stock without
restriction pursuant to Rule 144(k) promulgated under the 1933 Act (or successor
thereto), or (ii) the date on which the Investors shall have sold all the Common
Stock (the "REGISTRATION PERIOD"), the Company shall file all reports required
to be filed with the SEC pursuant to the 1934 Act, and the Company shall not
terminate its status as an issuer required to file reports under the 1934 Act
even if the 1934 Act or the rules and regulations thereunder would otherwise
permit such termination.

            d. Use of Proceeds. The Company will use the proceeds from the
sale of the Common Stock for substantially the same purposes and in
substantially the same amounts as indicated as follows: to pay certain accounts
payable and to use for working capital purposes.

            e. [Reserved.]

            f. Listing. The Company shall promptly secure the listing of all of
the Registrable Securities (as that term is defined in the Registration Rights
Agreement) upon each national securities exchange, automated quotation system or
bulletin board system, if any, upon which shares of the Company's common stock
are then listed (subject to official notice of issuance)



                                       10
<PAGE>   11

and shall maintain, so long as any other shares of common stock shall be so
listed, such listing of all Registrable Securities from time to time issuable
under the terms of the Transaction Documents. The Company shall maintain the
Common Stock's authorization for quotation on the Nasdaq National Market, Nasdaq
Small-Cap Market, Nasdaq OTC Bulletin Board, The New York Stock Exchange, Inc.
or The American Stock Exchange, Inc., as applicable (the "PRINCIPAL MARKET").
Neither the Company nor any of its Subsidiaries shall take any action which
would be reasonably expected to result in the delisting or suspension of Company
common stock on the Principal Market. The Company shall promptly, and in no
event later than the following Business Day, provide to each Buyer copies of any
notices it receives from the Principal Market regarding the continued
eligibility of Company common stock for listing on such automated quotation
system or securities exchange. The Company shall pay all fees and expenses in
connection with satisfying its obligations under this Section 4(f).

            g. [Reserved.]

            h. [Reserved.]

            i. [Reserved.]

            j. Independent Auditors. The Company shall, until at least three (3)
years after the Closing Date, maintain as its independent auditors an accounting
firm authorized to practice before the SEC.

             k. Corporate Existence and Taxes. The Company shall, until the
date that is three (3) years after the Closing Date, maintain its corporate
existence in good standing (provided, however, that the foregoing covenant shall
not prevent the Company from entering into any merger or corporate
reorganization as long as the surviving entity in such transaction, if not the
Company, has common stock listed for trading on the Principal Market and shall
pay all its taxes when due except for taxes which the Company disputes).

             l. Filing of Form 8-K. To the extent required by the 1934 Act,
on or before the first (1st) Business Day following the Closing Date, the
Company shall file a Form 8-K with the SEC describing the terms of the
transactions contemplated by the Transaction Documents in the form required by
the 1934 Act.

         5. TRANSFER AGENT INSTRUCTIONS.

         The Company shall issue irrevocable instructions to its transfer agent
(the "TRANSFER AGENT"), and any subsequent transfer agent, substantially in the
form of Exhibit B hereto (the "TRANSFER AGENT INSTRUCTIONS"). Prior to
registration of the Common Stock under the 1933 Act, all Common Stock
Certificates shall bear the restrictive legend specified in Section 2(g) of this
Agreement. The Company warrants that no instruction other than the Transfer
Agent Instructions



                                       11
<PAGE>   12

referred to in this Section 5, and stop transfer instructions to give effect to
Section 2(f) hereof will be given by the Company to its Transfer Agent and that
the Securities shall otherwise be freely transferable on the books and records
of the Company as and to the extent provided in this Agreement and the
Registration Rights Agreement. Nothing in this Section 5 shall affect in any way
each Buyer's obligations and agreements set forth in Section 2(g) to comply with
all applicable prospectus delivery requirements, if any, upon resale of the
Securities. If a Buyer provides the Company with an opinion of counsel, in a
generally acceptable form, to the effect that a public sale, assignment or
transfer of the Securities may be made without registration under the 1933 Act
or the Buyer provides the Company with reasonable assurances that the Securities
can be sold pursuant to Rule 144 without any restriction as to the number of
securities acquired as of a particular date that can then be immediately sold,
the Company shall permit the transfer. The Company acknowledges that a breach by
it of its obligations hereunder will cause irreparable harm to the Buyers by
vitiating the intent and purpose of the transaction contemplated hereby.
Accordingly, the Company acknowledges that the remedy at law for a breach of its
obligations under this Section 5 will be inadequate and agrees, in the event of
a breach or threatened breach by the Company of the provisions of this Section
5, that the Buyers shall be entitled, in addition to all other available
remedies, to an order and/or injunction restraining any breach and requiring
immediate issuance and transfer, without the necessity of showing economic loss
and without any bond or other security being required.

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

            The obligation of the Company hereunder to issue and sell the Common
Stock to each Buyer at the Closing is subject to the satisfaction, at or before
the Closing Date, of each of the following conditions, provided that these
conditions are for the Company's sole benefit and may be waived by the Company
at any time in its sole discretion by providing each Buyer with prior written
notice thereof:

            a. Such Buyer shall have executed each of the Transaction Documents,
where appropriate, to which it is a party and delivered the same to the Escrow
Agent for the transactions contemplated by this Agreement;

            b. The representations and warranties of such Buyer shall be true

agreements and conditions required by this Agreement to be performed, satisfied
or complied with by such Buyer at or prior to the Closing Date; and

            c. Such Buyer shall have delivered to the Escrow Agent such other
documents relating to the transactions contemplated by this Agreement as the
Escrow Agent may reasonable request.

         7. CONDITIONS TO EACH BUYER'S OBLIGATION TO PURCHASE.

            The obligation of each Buyer hereunder to purchase the Common
Stock at the Closing is subject to the satisfaction, at or before the Closing

for each Buyer's sole benefit and may be waived by such Buyer at any time in its
sole discretion by providing the Company with prior written notice thereof:

            a. The Company shall have executed each of the Transaction Documents
and delivered the same to the Escrow Agent;

            b. The Company's common stock shall be authorized for quotation on
the Principal Market and trading in Company common stock shall not have been
suspended by the SEC or the Principal Market;

            c. The representations and warranties of the Company shall be true
and correct as of the date when made and as of the Closing Date as though made
at that time (except for representations and warranties that speak as of a
specific date) and the Company shall have performed, satisfied and complied with
the covenants, agreements and conditions required by the Transaction Documents
to be performed, satisfied or complied with by the Company at or prior to the
Closing Date;

            d. The Company shall have delivered to the Escrow Agent the opinions
of the Company's outside legal counsel and general counsel dated as of the
Closing Date, in form, scope and substance reasonably satisfactory to such
Buyer, and such opinions shall collectively provide the opinions set forth in
Exhibit C attached hereto;

            e. [Reserved];

            f. The Transfer Agent Instructions shall have been delivered to and
acknowledged in writing by the Company's transfer agent and a copy of the
executed Transfer Agent Instructions shall have been delivered to the Escrow
Agent;

            g. The Company shall have made all filings under all applicable
federal and state securities laws necessary to consummate the issuance of the
Securities pursuant to this Agreement in compliance with such laws;

            h. [Reserved];

reasonably requested by such Buyer;

               ii. The Board of Directors of the Company shall have adopted
resolutions consistent with Section 3(b)(ii) above and in a form reasonably
acceptable to such Buyer;

               iii. The Company shall have delivered to such Buyer a certificate
evidencing the incorporation and good standing of the Company and each
Subsidiary in such corporation's state of incorporation issued by the Secretary
of State of such state of incorporation as of a date within 10 days of the
Closing Date;

               iv. The Company shall have delivered to such Buyer a certified

certificate, dated as the Closing Date, as to (A) the resolutions described in
Section 7(i)(ii) above, (B) the Certificate of Incorporation and (C) the Bylaws,
each as in effect at the Closing.

            j. The Company shall have delivered to the Escrow Agent such other
documents relating to the transactions contemplated by this Agreement as the

            k. Subject to Section 11(l) below, at Closing the Company shall

$5,000.00) incurred by the Buyers concerning the due diligence review of the
contemplated transactions and the Company, and the negotiation and preparation
of the Transaction Documents and the consummation of the transactions
contemplated thereby.

         8. INDEMNIFICATION.

            In consideration of each Buyer's execution and delivery of the
Transaction Documents and acquiring the Securities thereunder and in addition to
all of the Company's other obligations under the Transaction Documents, the
Company shall defend, protect, indemnify and hold harmless each Buyer and each
other holder of the Securities and all of their stockholders, officers,
directors, employees and direct or indirect investors and any of the foregoing
person's agents or other representatives (including, without limitation, those
retained in connection with the transactions contemplated by this Agreement)
(collectively, the "INDEMNITEES") from and against any and all actions, causes
of action, suits, claims, losses, costs, penalties, fees, liabilities



                                       14
<PAGE>   15

and damages, and expenses in connection therewith (irrespective of whether any
such Indemnitee is a party to the action for which indemnification hereunder is
sought), and including reasonable attorneys' fees and disbursements (the
"INDEMNIFIED LIABILITIES"), incurred by any Indemnitee as a result of, or
arising out of, or relating to (a) any misrepresentation or breach of any
representation or warranty made by the Company in the Transaction Documents or
any other certificate, instrument or document contemplated hereby or thereby,
(b) any breach of any covenant, agreement or obligation of the Company contained
in the Transaction Documents or any other certificate, instrument or document

            9. [Reserved.]

            10. ANTI-DILUTION ADJUSTMENTS.

            a. Dividend, Subdivision, Combination or Reclassification of Company
Common Stock. If the Corporation shall, at any time or from time to time, (a)
declare a dividend on the Company common stock payable in shares of its capital
stock (including Company common stock) or, (b) subdivide the outstanding Company
common stock or, (c) combine the outstanding Company common stock into a smaller
number of shares, or (d) issue any shares of its capital stock in a
reclassification of the Company common stock (excluding any such
reclassification in connection with a consolidation or merger in which the
Corporation is the continuing corporation), then in each such case, the number
of shares of Company common stock constituting the Common Shares at the time of
the record date for such dividend or of the effective date of such subdivision,
combination or reclassification and the number and kind of Common Shares on such
date shall be proportionately adjusted by virtue of such dividend, subdivision,
combination or reclassification. Any such adjustment to the Common Shares shall
become effective immediately after the record date of such dividend or the
effective date of such subdivision, combination or reclassification. Such
adjustment to the Common Shares shall be made successively whenever any event
listed above shall occur.

        11. GOVERNING LAW; MISCELLANEOUS.

            a. Governing Law; Jurisdiction; Jury Trial. This Agreement shall be
governed by and construed in all respects by the internal laws of the State of
Illinois (except for the proper application of the United States federal
securities laws), without giving effect to any choice of law or conflict of law
provision or rule (whether of the State of Illinois or any other jurisdictions)
that would cause the application of the laws of any jurisdictions other than the
State of Illinois. Each party hereby irrevocably submits to the non-exclusive
jurisdiction of the state and federal courts sitting in the City of Chicago.
EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO
REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN
CONNECTION




                                       15
<PAGE>   16

HEREWITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED
HEREBY.

            b. Counterparts. This Agreement may be executed in two or more
identical counterparts, all of which 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; provided that a facsimile signature
shall be considered due execution and shall be binding upon the signatory
thereto with the same force and effect as if the signature were an original, not
a facsimile signature.

            c. Headings. The headings of this Agreement are for convenience of
reference and shall not form part of, or affect the interpretation of, this
Agreement.

            d. Severability. If any provision of this Agreement shall be invalid
or unenforceable in any jurisdiction, such invalidity or unenforceability shall
not affect the validity or enforceability of the remainder of this Agreement in
that jurisdiction or the validity or enforceability of any provision of this
Agreement in any other jurisdiction.

            e. Entire Agreement; Amendments. This Agreement supersedes all
other prior oral or written agreements between the Buyers, the Company, their
affiliates and persons acting on their behalf with respect to the matters
discussed herein, and this Agreement and the instruments referenced herein
contain the entire understanding of the parties with respect to the matters
covered herein and therein and, except as specifically set forth herein or
therein, neither the Company nor any Buyer makes any representation, warranty,
covenant or undertaking with respect to such matters. No provision of this
Agreement may be amended other than by an instrument in writing signed by the
Company and holders of at least two-thirds (2/3) of the shares of Common Stock
held by the Buyers then outstanding, and no provision hereof may be waived other
than by an instrument in writing signed by the party against whom enforcement is
sought.

            f. Notices. Any notices, consents, waivers or other communications
required or permitted to be given under the terms of this Agreement must be in

            g. Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties and their respective successors and assigns,
including any purchasers of the Common Stock. The Company shall not assign this
Agreement or any rights or obligations hereunder without the prior written
consent of holders of at least two-thirds (2/3) of the shares of Common Stock
held by the Buyers. A Buyer may assign some or all of its rights hereunder
without the consent of the Company, provided, however, that any such assignment
shall not release such Buyer from its obligations hereunder unless such
obligations are assumed by such assignee and the Company has consented to such
assignment and assumption.

            h. No Third Party Beneficiaries. This Agreement is intended for the
benefit of the parties hereto and their respective permitted successors and
assigns, and is not for the benefit of, nor may any provision hereof be enforced
by, any other person.

            i. Survival. Unless this Agreement is terminated under Section

                                       17
<PAGE>   18

Closing. Each Buyer shall be responsible only for its own representations,
warranties, agreements and covenants hereunder.

            j. Publicity. The Company and each Buyer shall have the right to
approve before issuance any press releases or any other public statements with
respect to the transactions contemplated hereby; provided, however, that the
Company shall be entitled, without the prior approval of any Buyer, to make any
press release or other public disclosure with respect to such transactions as is
required by applicable law and regulations (although each Buyer shall be
consulted by the Company in connection with any such press release or other
public disclosure prior to its release and shall be provided with a copy
thereof).

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

            l. Termination. In the event that the Closing shall not have
occurred with respect to a Buyer on or before three (3) Business Days from the
date hereof due to the Company's or such Buyer's failure to satisfy the
conditions set forth in Sections 6 and 7 above (and the nonbreaching party's
failure to waive such unsatisfied condition(s)), the nonbreaching party shall
have the option to terminate this Agreement with respect to such breaching party
at the close of business on such date without liability of any party to any
other party; provided, however, that if this Agreement is terminated pursuant to
this Section 11(l), the Company shall remain obligated to reimburse the
nonbreaching Buyers for the expenses described in Section 7(k) above.

            m. Placement Agent. The Company acknowledges that it has engaged
MJM Capital, Inc. as placement agent in connection with the sale of the Common
Stock, which placement agent may have formally or informally engaged other
agents on its behalf. The Company shall be responsible for the payment of any
placement agent's fees or broker's commissions relating to or arising out of the
transactions contemplated hereby of any placement agent or broker engaged by the
Company. The Company shall pay, and hold each Buyer harmless against, any
liability, loss or expense (including, without limitation, attorneys' fees and
out of pocket expenses) arising in connection with any such claim.

            n. No Strict Construction. The language used in this Agreement
will be deemed to be the language chosen by the parties to express their mutual
intent, and no rules of strict construction will be applied against any party.

            o. Remedies. Each Buyer and each holder of the Securities shall
have all rights and remedies set forth in the Transaction Documents and all
rights and remedies which such holders have been granted at any time under any
other agreement or contract and all of the rights which such holders have under
any law. Any Person having any rights under any provision of this Agreement
shall be entitled to enforce such rights specifically (without posting a bond or
other



                                       18
<PAGE>   19

security), to recover damages by reason of any breach of any provision of this
Agreement and to exercise all other rights granted by law.

            p. Payment Set Aside. To the extent that the Company makes a payment
or payments to the Buyers hereunder or pursuant to the Transaction Documents or
the Buyers enforce or exercise their rights hereunder or thereunder, and such
payment or payments or the proceeds of such enforcement or exercise or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential,
set aside, recovered from, disgorged by or are required to be refunded, repaid
or otherwise restored to the Company, a trustee, receiver or any other person
under any law (including, without limitation, any bankruptcy law, state or
federal law, common law or equitable cause of action), then to the extent of any
such restoration the obligation or part thereof originally intended to be
satisfied shall be revived and continued in full force and effect as if such
payment had not been made or such enforcement or setoff had not occurred.

                            [Signature Page Follows]
