advisors, if any, have been afforded the opportunity to ask questions of the
Company. Notwithstanding the foregoing, the Company has not disclosed to the
Buyer any material nonpublic information and will not disclose such information
unless such information is disclosed to the public prior to or promptly
following such disclosure to the Buyer. Neither such inquiries nor any other due
diligence investigation conducted by Buyer or any of its advisors or
representatives shall modify, amend or affect Buyer's right to rely on the
Company's representations and warranties contained in Section 3 below. The Buyer
understands that its investment in the Securities involves a significant degree
of risk.

               e.  Governmental Review.  The Buyer understands that no United

States federal or state agency or any other government or governmental agency
has passed upon or made any recommendation or endorsement of the Securities.

               f.  Transfer or Re-sale.  The Buyer understands that (i) except
                   -------------------
as provided in the Registration Rights Agreement, the sale or re-sale of the
Securities has not been and is not being registered under the 1933 Act or any
applicable state securities laws, and the Securities may not be transferred
unless (a) the Securities are sold pursuant to an effective registration
statement under the 1933 Act, (b) the Buyer shall have delivered to the Company
an opinion of counsel (which opinion shall be in form, substance and scope
customary for opinions of counsel in comparable transactions) to the effect that
the Securities to be sold or transferred may be sold or transferred pursuant to
an exemption from such registration, (c) the Securities are sold or transferred
to an "affiliate" (as defined in Rule 144 promulgated under the 1933 Act (or a

Accredited Investor, or (d) the Securities are sold pursuant to Rule 144; (ii)
any sale of such Securities made in reliance on Rule 144 may be made only in
accordance with the terms of said Rule and further, if said Rule is not
applicable, any re-sale of such 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; and (iii) neither the Company nor any other person is under any
obligation to register such Securities under the 1933 Act or any state
securities laws or to comply with the terms and conditions of any exemption

Agreement). Notwithstanding the foregoing or anything else contained herein to
the contrary, the Securities may be pledged as collateral in connection with a
bona fide margin account or other lending arrangement.
---- ----

               g.  Legends.  The Buyer understands that the Debentures and the
                   -------
Warrants and, until such time as the Conversion Shares and Warrant Shares have
been registered under the 1933 Act as contemplated by the Registration Rights
Agreement or otherwise may be sold pursuant to Rule 144 without any restriction
as to the number of securities as of a particular date that can then be
immediately sold, the Conversion Shares and Warrant Shares may bear a
restrictive legend in substantially the following form (and a stop-transfer
order may be placed against transfer of the certificates for such Securities):

                                      -3-
<PAGE>

          "The securities represented by this certificate have not been
          registered under the Securities Act of 1933, as amended.  The
          securities may not be sold, transferred or assigned in the
          absence of an effective registration statement for the securities
          under said Act, or an opinion of counsel, in form, substance and
          scope customary for opinions of counsel in comparable transactions,
          that registration is not required under said Act or unless sold
          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 any Security upon which it is
stamped, if, unless otherwise required by applicable state securities laws, (a)
such Security is registered for sale under an effective registration statement
filed under the 1933 Act or otherwise may be sold pursuant to Rule 144 without
any restriction as to the number of securities as of a particular date that can
then be immediately sold, or (b) such holder provides the Company with an
opinion of counsel, in form, substance and scope customary for opinions of
counsel in comparable transactions, to the effect that a public sale or transfer
of such Security may be made without registration under the 1933 Act and such
sale or transfer is effected or (c) such holder provides the Company with
reasonable assurances that such Security can be sold pursuant to Rule 144.  The
Buyer agrees to sell all Securities, including those represented by a
certificate(s) from which the legend has been removed, in compliance with
applicable prospectus delivery requirements, if any.

               h.  Authorization; Enforcement. This Agreement and the
                   --------------------------
Registration Rights Agreement have been duly and validly authorized. This
Agreement has been duly executed and delivered on behalf of the Buyer, and this
Agreement constitutes, and upon execution and delivery by the Buyer of the

Company's Certificate of Incorporation as in effect on the date hereof
("Certificate of Incorporation"), the Company's By-laws, as in effect on the
date hereof (the "By-laws"), and the terms of all securities convertible into or
exercisable for Common Stock of the Company and the material rights of the
holders thereof in respect thereto.  The Company shall provide the Buyer with a
written update of this representation signed by the Company's Chief Executive or
Chief Financial Officer on behalf of the Company as of the Closing Date.

                   ------------------

stockholders of the Company and will not impose personal liability upon the

its obligation to issue Conversion Shares and Warrant Shares upon conversion of

stockholders of the Company.

               f.  No Conflicts.  The execution, delivery and performance of
                   ------------
this Agreement, the Registration Rights Agreement, the Debentures and the
Warrants by the Company and the consummation by the Company of the transactions
contemplated hereby and thereby (including, without limitation, the issuance and
reservation for issuance of the Conversion Shares and Warrant Shares) will not
(i) conflict with or result in a violation of any provision of the Certificate
of Incorporation or By-laws or (ii) violate or conflict with, or result in a
breach of any provision of, or constitute a default (or an event which with
notice or lapse of time or both could become a default) under, or give to others
any rights of termination, amendment, acceleration or cancellation of, any
agreement, indenture, patent, patent license or instrument to which the Company
or any of its Subsidiaries is a party, or (iii) result in a violation of any
law, rule, regulation, order, judgment or decree (including federal and state
securities laws and regulations and regulations of any self-regulatory
organizations to which the Company or its securities are subject) applicable to
the Company or any of its Subsidiaries or by which any property or asset of the
Company or any of its Subsidiaries is bound or affected (except for such
conflicts, defaults, terminations, amendments, accelerations, cancellations and
violations as would not, individually or in the aggregate, have a Material
Adverse Effect). Neither the Company nor any of its Subsidiaries is in violation
of its Certificate of Incorporation, By-laws or other organizational documents
and neither the Company nor any of its Subsidiaries is in default (and no event
has occurred which with notice or lapse of time or both could put the

                                      -6-
<PAGE>

Company or any of its Subsidiaries in default) under, and neither the Company
nor any of its Subsidiaries has taken any action or failed to take any action
that would give to others any rights of termination, amendment, acceleration or
cancellation of, any agreement, indenture or instrument to which the Company or
any of its Subsidiaries is a party or by which any property or assets of the
Company or any of its Subsidiaries is bound or affected, except for possible
defaults as would not, individually or in the aggregate, have a Material Adverse
Effect. The businesses of the Company and its Subsidiaries, if any, are not
being conducted, and shall not be conducted so long as a Buyer owns any of the
Securities, in violation of any law, ordinance or regulation of any governmental
entity.  Except as specifically contemplated by this Agreement and as required
under the 1933 Act and any applicable state securities laws, the Company is not
required to obtain any consent, authorization or order of, or make any filing or
registration with, any court, governmental agency, regulatory agency, self
regulatory organization or stock market or any third party in order for it to
execute, deliver or perform any of its obligations under this Agreement, the
Registration Rights Agreement, the Debentures or the Warrants in accordance with
the terms hereof or thereof or to issue and sell the Debentures and Warrants in

the date hereof.  The Company is not in violation of the listing requirements of
the Over-the-Counter Bulletin Board (the "OTCBB") and does not reasonably
anticipate that the Common Stock will be delisted by the OTCBB in the
foreseeable future.  The Company and its Subsidiaries are unaware of any facts
or circumstances which might give rise to any of the foregoing.

               g.  SEC Documents; Financial Statements. Since May 31, 1998, the
                   -----------------------------------
Company has timely filed all reports, schedules, forms, statements and other
documents required to be filed by it with the SEC pursuant to the reporting
requirements of the 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, amended financial statements and schedules thereto and
documents (other than exhibits to such documents) incorporated by reference
therein, being hereinafter referred to herein as the "SEC Documents"). The
Company has delivered, through filings with the EDGAR system of the SEC, to each
Buyer true and complete copies of the SEC Documents, except for such exhibits
and incorporated documents. As of their respective dates, the SEC Documents
complied in all material respects with the requirements of the 1934 Act and the
rules and regulations of the SEC promulgated thereunder applicable to the SEC
Documents, and none of the SEC Documents, at the time they were filed with the
SEC, contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading. None of the statements made in any such SEC Documents is, or has
been, required to be amended or updated under applicable law (except for such
statements as have been amended or updated in subsequent filings prior the date
hereof). 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 United States generally accepted accounting principles,
consistently applied, during the periods involved (except (i) as may be
otherwise

                                      -7-
<PAGE>

indicated in such financial statements or the notes thereto, or (ii) in the case
of unaudited interim statements, to the extent they may not include footnotes or
may be condensed or summary statements) and fairly present in all material
respects the consolidated financial position of the Company and its consolidated
Subsidiaries as of the dates thereof and the consolidated results of their
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end audit adjustments). Except as set forth
in the financial statements of the Company included in the SEC Documents, the
Company has no liabilities, contingent or otherwise, other than (i) liabilities
incurred in the ordinary course of business subsequent to May 31, 2000 and (ii)
obligations under contracts and commitments incurred in the ordinary course of
business and not required under generally accepted accounting principles to be
reflected in such financial statements, which, individually or in the aggregate,
are not material to the financial condition or operating results of the Company.

               h.  Absence of Certain Changes.  Since May 31, 2000, there has
                   --------------------------
been no material adverse change and no material adverse development in the
assets, liabilities, business, properties, operations, financial condition,
results of operations or prospects of the Company or any of its Subsidiaries.

               i.  Absence of Litigation.  There is no action, suit, claim,
                   ---------------------
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 or any of its Subsidiaries, or their officers or directors
in their capacity as such, that could have a Material Adverse Effect. Schedule
3(i) contains a complete list and summary description of any pending or
threatened proceeding against or affecting the Company or any of its
Subsidiaries, without regard to whether it would have a Material Adverse Effect.
The Company and its Subsidiaries are unaware of any facts or circumstances which
might give rise to any of the foregoing.

               j.  Patents, Copyrights, etc.
                   ------------------------

                    (i)  The Company and each of its Subsidiaries owns or
possesses the requisite licenses or rights to use all patents, patent
applications, patent rights, inventions, know-how, trade secrets, trademarks,
trademark applications, service marks, service names, trade names and copyrights
("Intellectual Property") necessary to enable it to conduct its business as now
operated (and, except as set forth in Schedule 3(j) hereof, to the best of the
Company's knowledge, as presently contemplated to be operated in the future);
there is no claim or action by any person pertaining to, or proceeding pending,
or to the Company's knowledge threatened, which challenges the right of the
Company or of a Subsidiary with respect to any Intellectual Property necessary
to enable it to conduct its business as now operated (and, except as set forth
in Schedule 3(j) hereof, to the best of the Company's knowledge, as presently
contemplated to be operated in the future); to the best of the Company's
knowledge, the Company's or its Subsidiaries' current and intended products,
services and processes do not infringe on any Intellectual Property or other
rights held by any person; and the Company is unaware of any facts or
circumstances which might give rise to any of the foregoing. The Company and
each of its Subsidiaries have taken reasonable security measures to protect the
secrecy, confidentiality and value of their Intellectual Property.

                    (ii) All of the Company's computer software and computer
hardware, and other similar or related items of automated, computerized or
software systems that are used or relied on by the Company in the conduct of its
business or that were, or currently are being, sold or licensed by the Company
to customers (collectively, "Information Technology"), are Year 2000 Compliant.
For purposes of this Agreement, the term "Year 2000 Compliant" means, with
respect to the Company's Information Technology, that the Information Technology
is designed to be used prior to, during and after the calendar Year 2000 A.D.,
and the Information Technology used during each such time period will accurately
receive, provide and process date and time data (including, but not limited to,
calculating, comparing and sequencing) from, into and between the 20th and 21st
centuries, including the years 1999 and 2000, and leap-year calculations, and
will not malfunction, cease to function, or provide invalid or incorrect results
as a result of the date or time data, to the extent that other information
technology, used in combination with the Information Technology, properly
exchanges date and time data with it.

               k.  No Materially Adverse Contracts, Etc. Neither the Company nor
                   ------------------------------------
any of its Subsidiaries is subject to any charter, corporate or other legal
restriction, or any judgment, decree, order, rule or regulation which in the
judgment of the Company's officers has or is expected in the future to have a
Material Adverse Effect. Neither the Company nor any of its Subsidiaries is a
party to any contract or agreement which in the judgment of the Company's
officers has or is expected to have a Material Adverse Effect.

               l.  Tax Status.  Except as set forth on Schedule 3(l), the
                   ----------
Company and each of its Subsidiaries has made or filed all federal, state and
foreign 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 provisions 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. The Company has not executed a waiver with respect to
the statute of limitations relating to the assessment or collection of any
foreign, federal, statue or local tax. Except as set forth on Schedule 3(l),
none of the Company's tax returns is presently being audited by any taxing
authority.

               m.  Certain Transactions.  Except as set forth on Schedule 3(m)
                   --------------------
and except for arm's length transactions pursuant to which the Company or any of
its Subsidiaries makes payments in the ordinary course of business upon terms no
less favorable than the Company or any of its Subsidiaries could obtain from
third parties and other than the grant of stock options disclosed on Schedule
3(c), none of the officers, directors, or employees of the Company is presently

<PAGE>

other entity in which any officer, director, or any such employee has a
substantial interest or is an officer, director, trustee or partner.

               n.  Disclosure.  All information relating to or concerning the
                   ----------
Company or any of its Subsidiaries set forth in this Agreement and provided to
the Buyers pursuant to Section 2(d) hereof and otherwise in connection with the
transactions contemplated hereby is true and correct in all material respects
and the Company has not omitted to state any material fact necessary in order to
make the statements made herein or therein, in light of the circumstances under
which they were made, not misleading. No event or circumstance has occurred or
exists with respect to the Company or any of its Subsidiaries or its or their
business, properties, prospects, operations or financial conditions, which,
under applicable law, rule or regulation, requires public disclosure or
announcement by the Company but which has not been so publicly announced or
disclosed (assuming for this purpose that the Company's reports filed under the
1934 Act are being incorporated into an effective registration statement filed
by the Company under the 1933 Act).

               o.  Acknowledgment Regarding Buyers' Purchase of Securities. The
                   -------------------------------------------------------
Company acknowledges and agrees that the Buyers are acting solely in the
capacity of arm's length purchasers with respect to this Agreement and the
transactions contemplated hereby. The Company further acknowledges that no Buyer
is acting as a financial advisor or fiduciary of the Company (or in any similar
capacity) with respect to this Agreement and the transactions contemplated
hereby and any statement made by any Buyer or any of their respective
representatives or agents in connection with this Agreement and the transactions
contemplated hereby is not advice or a recommendation and is merely incidental
to the Buyers' purchase of the Securities. The Company further represents to
each Buyer that the Company's decision to enter into this Agreement has been
based solely on the independent evaluation of the Company and its
representatives.

               p.  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 in any security or solicited any offers to
buy any security under circumstances that would require registration under the
1933 Act of the issuance of the Securities to the Buyers. The issuance of the
Securities to the Buyers will not be integrated with any other issuance of the
Company's securities (past, current or future) for purposes of any stockholder
approval provisions applicable to the Company or its securities.

               q.  No Brokers.  The Company has taken no action which would give
                   ----------
rise to any claim by any person for brokerage commissions, transaction fees or
similar payments relating to this Agreement or the transactions contemplated
hereby.

               r.  Permits; Compliance.  The Company and each of its
                   -------------------
Subsidiaries is in possession of all franchises, grants, authorizations,
licenses, permits, easements, variances, exemptions, consents, certificates,
approvals and orders necessary to own, lease and operate its properties and to
carry on its business as it is now being conducted (collectively, the "Company
Permits"), and there is no action pending or, to the knowledge of the Company,
threatened regarding suspension or cancellation of any of the Company

                                      -10-
<PAGE>

Permits. Neither the Company nor any of its Subsidiaries is in conflict with, or
in default or violation of, any of the Company Permits, except for any such
conflicts, defaults or violations which, individually or in the aggregate, would
not reasonably be expected to have a Material Adverse Effect. Since May 31,
2000, neither the Company nor any of its Subsidiaries has received any
notification with respect to possible conflicts, defaults or violations of
applicable laws, except for notices relating to possible conflicts, defaults or
violations, which conflicts, defaults or violations would not have a Material
Adverse Effect.

               s.  Environmental Matters.
                   ---------------------

                    (i)    Except as set forth in Schedule 3(s), there are, to
the Company's knowledge, with respect to the Company or any of its Subsidiaries
or any predecessor of the Company, no past or present violations of
Environmental Laws (as defined below), releases of any material into the
environment, actions, activities, circumstances, conditions, events, incidents,
or contractual obligations which may give rise to any common law environmental
liability or any liability under the Comprehensive Environmental Response,
Compensation and Liability Act of 1980 or similar federal, state, local or
foreign laws and neither the Company nor any of its Subsidiaries has received
any notice with respect to any of the foregoing, nor is any action pending or,
to the Company's knowledge, threatened in connection with any of the foregoing.
The term "Environmental Laws" means all federal, state, local or foreign laws
relating to pollution or protection of human health or the environment
(including, without limitation, ambient air, surface water, groundwater, land
surface or subsurface strata), including, without limitation, laws relating to
emissions, discharges, releases or threatened releases of chemicals, pollutants
contaminants, or toxic or hazardous substances or wastes (collectively,
"Hazardous Materials") into the environment, or otherwise relating to the
manufacture, processing, distribution, use, treatment, storage, disposal,
transport or handling of Hazardous Materials, as well as all authorizations,
codes, decrees, demands or demand letters, injunctions, judgments, licenses,
notices or notice letters, orders, permits, plans or regulations issued,
entered, promulgated or approved thereunder.

                    (ii)   Other than those that are or were stored, used or
disposed of in compliance with applicable law, no Hazardous Materials are
contained on or about any real property currently owned, leased or used by the
Company or any of its Subsidiaries, and no Hazardous Materials were released on
or about any real property previously owned, leased or used by the Company or
any of its Subsidiaries during the period the property was owned, leased or used
by the Company or any of its Subsidiaries, except in the normal course of the
Company's or any of its Subsidiaries' business.

                    (iii)  Except as set forth in Schedule 3(s), there are no
underground storage tanks on or under any real property owned, leased or used by
the Company or any of its Subsidiaries that are not in compliance with
applicable law.

               t.  Title to Property.  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 Schedule 3(t) or
such as would not have a Material Adverse Effect. Any real property and
facilities held under lease by the Company and its Subsidiaries are held by them
under valid,

                                      -11-
<PAGE>

subsisting and enforceable leases with such exceptions as would not have a
Material Adverse Effect.

               u.  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. Neither the Company nor any such Subsidiary has any
reason to believe that it will not be able to renew its existing insurance
coverage as and when such coverage expires or to obtain similar coverage from
similar insurers as may be necessary to continue its business at a cost that
would not have a Material Adverse Effect.

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

               w.  Foreign Corrupt Practices. Neither the Company, nor any of
                   -------------------------
its Subsidiaries, nor any director, officer, agent, employee or other person
acting on behalf of the Company or any Subsidiary has, in the course of his
actions for, or on behalf of, the Company, used any corporate funds for any
unlawful contribution, gift, entertainment or other unlawful expenses relating
to political activity; made any direct or indirect unlawful payment to any
foreign or domestic government official or employee from corporate funds;
violated or is in violation of any provision of the U.S. Foreign Corrupt
Practices Act of 1977, as amended, or made any bribe, rebate, payoff, influence
payment, kickback or other unlawful payment to any foreign or domestic
government official or employee.

               x.  Solvency.  The Company (after giving effect to the
                   --------
transactions contemplated by this Agreement) is solvent (i.e., its assets have a
                                                         ---
fair market value in excess of the amount required to pay its probable
liabilities on its existing debts as they become absolute and matured) and
currently the Company has no information that would lead it to reasonably
conclude that the Company would not have the ability to, nor does it intend to
take any action that would impair its ability to, pay its debts from time to
time incurred in connection therewith as such debts mature. The Company did not
receive a qualified opinion from its auditors with respect to its most recent
fiscal year end and does not anticipate or know of any basis upon which its
auditors might issue a qualified opinion in respect of its current fiscal year.

               y.  No Investment Company. The Company is not, and upon the
                   ---------------------
issuance and sale of the Securities as contemplated by this Agreement will not
be an "investment company" required to be registered under the Investment
Company Act of 1940 (an "Investment Company"). The Company is not controlled by
an Investment Company.

                                      -12-

          4.  COVENANTS.
              ---------

               a.  Best Efforts.  The parties shall use their best efforts to
                   ------------
satisfy timely each of the conditions described in Section 6 and 7 of this
Agreement.

               b.  Form D; Blue Sky Laws. 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 to qualify the Securities for sale to the Buyers at the
applicable closing pursuant to this Agreement under applicable securities or
"blue sky" laws of the states of the United States (or to obtain an exemption
from such qualification), and shall provide evidence of any such action so taken
to each Buyer on or prior to the Closing Date.

               c.  Reporting Status; Eligibility to Use Form SB-2 or Form S-1.
                   ----------------------------------------------------------
The Company's Common Stock is registered under Section 12(g) of the 1934 Act.
The Company represents and warrants that it meets the requirements for the use
of Form SB-2 or Form S-1 for registration of the sale by the Buyer of the
Registrable Securities (as defined in the Registration Rights Agreement). So
long as the Buyer beneficially owns any of the Securities, the Company shall
timely 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 permit such termination. The Company further agrees
to file all reports required to be filed by the Company with the SEC in a timely
manner so as to become eligible, and thereafter to maintain its eligibility, for
the use of Form S-3. The Company, upon review and approval of the Buyers, shall
issue a press release describing the materials terms of the transaction
contemplated hereby as soon as practicable following the Closing Date but in no
event more than two (2) business days of the Closing Date, and shall file with
the SEC a Current Report on Form 8-K describing the material terms of the
transaction contemplated hereby within five (5) business days of the Closing
Date, which press release and Form 8-K shall be subject to prior review by the
Buyers.

               d.  Use of Proceeds. The Company shall use the proceeds from the
                   ---------------
sale of the Debentures and the Warrants in the manner set forth in Schedule 4(d)
attached hereto and made a part hereof and shall not, directly or indirectly,
use such proceeds for any loan to or investment in any other corporation,
partnership, enterprise or other person (except in connection with its currently
existing direct or indirect Subsidiaries).

               e.  Future Offerings. Subject to the exceptions described below,
                   ----------------
the Company will not, without the prior written consent of a majority-in-
interest of the Buyers, negotiate or contract with any party to obtain
additional equity financing (including debt financing with an equity component)
that involves (A) the issuance of Common Stock or (B) the issuance of
convertible securities that are convertible into an indeterminate number of
shares of Common Stock or (C) the issuance of warrants during the period (the
"Lock-up Period") beginning on the Closing Date and ending one hundred eighty
(180) days from the date the Registration Statement (as defined in the
Registration Rights Agreement) is declared effective (plus any days in which
sales cannot be made thereunder). In addition, subject to the exceptions
described below, the Company will not conduct any equity financing (including
debt with an

                                      -13-
<PAGE>

equity component) ("Future Offerings") during the period beginning on the
Closing Date and ending two (2) years after the end of the Lock-up Period unless
it shall have first delivered to each Buyer, at least fifteen (15) business days
prior to the closing of such Future Offering, written notice describing the
proposed Future Offering, including the terms and conditions thereof and
proposed definitive documentation to be entered into in connection therewith,
and providing each Buyer an option during the ten (10) day period following
delivery of such notice to purchase its pro rata share (based on the ratio that
the aggregate principal amount of Debentures purchased by it hereunder bears to
the aggregate principal amount of Debentures purchased hereunder) of the
securities being offered in the Future Offering on the same terms as
contemplated by such Future Offering (the limitations referred to in this
sentence and the preceding sentence are collectively referred to as the "Capital
Raising Limitations"). In the event the terms and conditions of a proposed
Future Offering are amended in any respect after delivery of the notice to the
Buyers concerning the proposed Future Offering, the Company shall deliver a new
notice to each Buyer describing the amended terms and conditions of the proposed
Future Offering and each Buyer thereafter shall have an option during the ten
(10) day period following delivery of such new notice to purchase its pro rata
share of the securities being offered on the same terms as contemplated by such
proposed Future Offering, as amended. The foregoing sentence shall apply to
successive amendments to the terms and conditions of any proposed Future
Offering. The Capital Raising Limitations shall not apply to the issuance of
securities upon exercise or conversion of the Company's options, warrants or
other convertible securities outstanding as of the date hereof or to the grant
of additional options or warrants, or the issuance of additional securities,
under any Company stock option or restricted stock plan approved by the
Stockholders of the Company. In the event that the Company completes a Future
Offering on terms more favorable than the transaction contemplated hereby, the
terms of the Debentures, the Additional Debentures, the Warrants and the
Additional Warrants will be amended to reflect such more favorable terms.

               f.  Expenses. At the Closing, the Company shall reimburse Buyers
                   --------
for expenses incurred by it in connection with the negotiation, preparation,
execution, delivery and performance of this Agreement and the other agreements
to be executed in connection herewith, including, without limitation, attorneys'
and consultants' fees and expenses.

               g.  Financial Information. The Company agrees to send the
                   ---------------------
following reports to each Buyer until such Buyer transfers, assigns, or sells
all of the Securities: (i) within ten (10) days after the filing with the SEC, a
copy of its Annual Report on Form 10-KSB, its Quarterly Reports on Form 10-QSB
and any Current Reports on Form 8-K; (ii) within one (1) day after release,
copies of all press releases issued by the Company or any of its Subsidiaries;
and (iii) contemporaneously with the making available or giving to the
stockholders of the Company, copies of any notices or other information the
Company makes available or gives to such stockholders. Information contemplated
to be sent pursuant to the Section 4(g) may be sent electronically.

               h.  Reservation of Shares. The Company shall at all times have
                   ---------------------
authorized, and reserved for the purpose of issuance, a sufficient number of
shares of Common Stock to provide for the full conversion or exercise of the
outstanding Debentures and Additional Debentures (including all accrued unpaid
interest thereon) and the Warrants and Additional Warrants and issuance of the
Conversion Shares and Warrant Shares in connection therewith

                                      -14-
<PAGE>

(based on the Conversion Price or Exercise Price in effect from time to time)
and as otherwise required by the Debentures. The Company shall not reduce the
number of shares of Common Stock reserved for issuance upon conversion of
Debentures and Additional Debentures and exercise of the Warrants and Additional
Warrants without the consent of each Buyer. The Company shall use its best
efforts at all times to maintain the number of shares of Common Stock so
reserved for issuance at no less than two (2) times the number that is then
actually issuable upon full conversion of the Debentures and Additional
Debentures and upon exercise of the Warrants and Additional Warrants (based on
the Conversion Price or the Exercise Price in effect from time to time and
including all accrued and unpaid interest on the Debentures). If at any time the
number of shares of Common Stock authorized and reserved for issuance is below
the number of Conversion Shares and Warrant Shares issued and issuable upon
conversion of the Debentures and Additional Debentures and exercise of the
Warrants and Additional Warrants (based on the Conversion Price or the Exercise
Price then in effect and including all accrued and unpaid interest on the
Debentures), the Company will promptly take all corporate action necessary to
authorize and reserve a sufficient number of shares, including, without
limitation, calling a special meeting of stockholders to authorize additional
shares to meet the Company's obligations under this Section 4(h), in the case of
an insufficient number of authorized shares, and using its best efforts to
obtain stockholder approval of an increase in such authorized number of shares.

               i.  Listing.  The Company shall promptly secure the listing of
                   -------
the Conversion Shares and Warrant Shares upon each national securities exchange
or automated quotation system, if any, upon which shares of Common Stock are
then listed (subject to official notice of issuance) and, so long as any Buyer
owns any of the Securities, shall maintain, so long as any other shares of
Common Stock shall be so listed, such listing of all Conversion Shares and
Warrant Shares from time to time issuable upon conversion of the Debentures or
exercise of the Warrants. The Company will obtain and, so long as any Buyer owns
any of the Securities, maintain the listing and trading of its Common Stock on
the OTCBB, the Nasdaq National Market ("Nasdaq"), the Nasdaq SmallCap Market
("Nasdaq SmallCap"), the New York Stock Exchange ("NYSE"), or the American Stock
Exchange ("AMEX") and will comply in all respects with the Company's reporting,
filing and other obligations under the bylaws or rules of the National
Association of Securities Dealers ("NASD") and such exchanges, as applicable.
The Company shall promptly provide to each Buyer copies of any notices it
receives from the OTCBB and any other exchanges or quotation systems on which
the Common Stock is then listed regarding the continued eligibility of the
Common Stock for listing on such exchanges and quotation systems.

               j.  Corporate Existence. So long as a Buyer beneficially owns any
                   -------------------
Debentures or Warrants, the Company shall maintain its corporate existence and
shall not sell all or substantially all of the Company's assets, except in the
event of a merger or consolidation or sale of all or substantially all of the
Company's assets, where the surviving or successor entity in such transaction
(i) assumes the Company's obligations hereunder and under the agreements and
instruments entered into in connection herewith and (ii) is a publicly traded
corporation whose Common Stock is listed for trading on the OTCBB, Nasdaq,
Nasdaq SmallCap, NYSE or AMEX.

                                      -15-
<PAGE>

               k.  No Integration.  The Company shall not make any future offers
                   --------------
or sales of any security (other than the Securities) under circumstances that
would require registration of the Securities being offered or sold hereunder
under the 1933 Act or cause the offering of the Securities to be integrated with
any other offering of securities by the Company for the purpose of any
stockholder approval provision applicable to the Company or its securities.

               l.  Subsequent Investment.  The Company and the Buyers agree
                   ---------------------
that, upon the declaration of effectiveness of the Registration Statement to be
filed pursuant to the Registration Rights Agreement (the "Effective Date"), the
Buyers shall purchase additional debentures ("Additional Debentures") in the
aggregate principal amount of Two Hundred Thousand Dollars ($200,000) and
receive additional warrants ("Additional Warrants") to purchase (under terms
identical to the Warrants) an aggregate of 100,000 shares of Common Stock, for
an aggregate purchase price of Two Hundred Thousand Dollars ($200,000), with the
closing of such purchase to occur within thirty (30) days of the Effective Date;
provided, however, that the obligation of each Buyer to purchase the Additional
--------  -------
Debentures and the Additional Warrants is subject to the satisfaction, at or
before the closing of such purchase and sale, of the conditions set forth in
Section 7. The terms of the Additional Debentures and the Additional Warrants
shall be identical to the terms of the Debentures and Warrants to be issued on
the Closing Date. The Common Stock underlying the Additional Debentures and the
Additional Warrants shall be Registrable Securities (as defined in the
Registration Rights Agreement) and shall be included in the Registration
Statement to be filed pursuant to the Registration Rights Agreement.

          5.  TRANSFER AGENT INSTRUCTIONS.  The Company shall issue irrevocable
              ---------------------------
instructions to its transfer agent to issue certificates, registered in the name
of each Buyer or its nominee, for the Conversion Shares and Warrant Shares in
such amounts as specified from time to time by each Buyer to the Company upon
conversion of the Debentures or exercise of the Warrants in accordance with the
terms thereof (the "Irrevocable Transfer Agent Instructions"). Prior to
registration of the Conversion Shares and Warrant Shares under the 1933 Act or
the date on which the Conversion Shares and Warrant Shares may be sold pursuant
to Rule 144 without any restriction as to the number of Securities as of a
particular date that can then be immediately sold, all such certificates shall
bear the restrictive legend specified in Section 2(g) of this Agreement. The
Company warrants that no instruction other than the Irrevocable Transfer Agent
Instructions referred to in this Section 5, and stop transfer instructions to
give effect to Section 2(f) hereof (in the case of the Conversion Shares and
Warrant Shares, prior to registration of the Conversion Shares and Warrant
Shares under the 1933 Act or the date on which the Conversion Shares and Warrant
Shares may be sold pursuant to Rule 144 without any restriction as to the number
of Securities as of a particular date that can then be immediately sold), 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 shall affect in any way the Buyer's obligations and
agreement set forth in Section 2(g) hereof to comply with all applicable
prospectus delivery requirements, if any, upon re-sale of the Securities. If a
Buyer provides the Company with (i) an opinion of counsel in form, substance and
scope customary for opinions in comparable transactions, to the effect that a
public sale or

                                      -16-

transfer of such Securities may be made without registration under the 1933 Act
and such sale or transfer is effected or (ii) the Buyer provides reasonable
assurances that the Securities can be sold pursuant to Rule 144, the Company
shall permit the transfer, and, in the case of the Conversion Shares and Warrant
Shares, promptly instruct its transfer agent to issue one or more certificates,
free from restrictive legend, in such name and in such denominations as
specified by such Buyer. 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 transactions 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, that the
Buyers shall be entitled, in addition to all other available remedies, to an
injunction restraining any breach and requiring immediate transfer, without the
necessity of showing economic loss and without any bond or other security being
required.
