Freedom is indebted to Collett on various demand promissory notes (the "Promissory Notes"), as more specifically described in Appendix 2 attached hereto, in the aggregate
amount of $2,199,053, including accrued and unpaid interest through the date hereof; and 

        WHEREAS,
Freedom has agreed to secure its obligations to Collett under the Indemnification Agreement and the Promissory Notes by granting a first security interest to Collett in shares
of preferred and common stock of Florida Gaming Corporation owned by Freedom, as more specifically described in Appendix 3 attached hereto. 

        NOW,
THEREFORE, in order to secure Freedom's obligations to Collett under the Indemnification Agreement and to secure the payment of the principal and interest on the Promissory Notes,
Freedom hereby sells, assigns, transfers, pledges, hypothecates, and sets over unto Collett and his heirs, personal representatives and permitted assigns, 1,772,315 issued and outstanding shares of
common stock and $1,000,000 face amount of Series F and $200,000 face amount of Series E Preferred Stock of Florida Gaming Corporation (the "Shares"). 

        TO
HAVE AND TO HOLD the same unto Collett, his heirs, personal representatives and permitted assigns forever, upon the terms herein set forth, to secure Freedom's performance of its
responsibilities and obligations under the Indemnification Agreement, the Promissory Notes, and this Security Agreement. 

        PROVIDED,
HOWEVER, if all sums payable in respect of the Indemnity Agreement and the Promissory Notes in accordance with their terms are paid, and all obligations contained herein are
performed in full, the rights of Collett hereunder shall cease, determine and be void, and Collett shall release the Shares and deliver them to Freedom or to whomever shall be entitled to receive the
Shares. 

 1.    Covenants.  

        1.1    Freedom covenants that it is the lawful owner of the Shares, free and clear of all liens, pledges, charges, conversion rights or encumbrances
whatsoever, and that is has good right, full power and lawful authority to sell, assign, transfer, pledge, hypothecate, set over and confirm the Shares to Collett and will preserve, warrant and defend
the same to Collett. 

        1.2    Freedom
covenants that it will at all times preserve, warrant and defend Collett's right and security interest in the Shares against the claims of all persons and
parties whomever and that it will not do or suffer any matter or thing to be done or to exist whereby the lien of this Security Agreement on the Shares might be lost, impaired, or threatened, and it
will take or cause to be taken all action necessary so that the lien hereof on the Shares shall be duly preserved.

 2.    Pledged Shares.  

        2.1    The stock certificates representing the Shares issued in the name of Freedom, together with stock powers executed by Freedom and endorsed in
blank, shall be delivered to Collett simultaneously with
the execution of this Agreement and shall be held in the custody of Collett subject to the terms and conditions of this Security Agreement. The Shares shall not be transferred or reissued in any name
other than Freedom unless an event of default shall have occurred and be continuing for 30 days. 

        2.2    Unless
an event of default shall have occurred and be continuing, Freedom shall be entitled to receive all cash dividends paid on the Shares. 

        2.3    Unless
an event of default shall have occurred and be continuing, Freedom shall have the right to vote upon and represent, or give any consent in respect of, the Shares
for all purposes not inconsistent with the provisions of this Security Agreement, with the same force and effect as though the Shares were not subject hereto. 

        2.4    If
Florida Gaming Corporation shall at any time (a) make a distribution or pay a dividend on the Shares in shares of common stock of Florida Gaming Corporation
("FGC Common Stock"), (b) subdivide the outstanding shares of FGC Common Stock into a greater number of shares, or (C) combine the outstanding shares of FGC Common Stock into a smaller
number of shares, then the number of Shares subject to this Security Agreement shall be adjusted to reflect such action. 

        2.5    If
Florida Gaming Corporation merges into another corporation, or any merger of another corporation into Florida Gaming Corporation (excluding a merger in which Florida
Gaming Corporation is the surviving or continuing corporation and which does not result in any reclassification, conversion, exchange or cancellation of the outstanding shares of FGC Common or
Preferred Stock), or in the case a sale of all or substantially all of Florida Gaming Corporation's assets to another corporation or person shall be effected, then, as a condition to Freedom voting
the Shares in favor of such merger or sale, Freedom shall take such actions as Collett may reasonably request to protect and preserve the value of the Shares and Collett's security interest in the
Shares. 

        3.    Default.    A default hereunder shall be deemed to have occurred in the event (a) Freedom does not
indemnify and hold Collett harmless in accordance with the terms of the Indemnification Agreement; (b) Freedom does not pay the Promissory Notes in accordance with their terms;
(c) Freedom is placed in receivership or declared a bankrupt, or (d) Freedom breaches any warranty contained in this Security Agreement. 

 4.    Remedies.  

        4.1    If an event of default shall have occurred, Collett may, to the extent permitted by federal and state securities laws, sell at one or more sales,
all or part of the Shares, such sale or sales to be made at public auction or private transaction at such place or places, and at such time or times and upon such
terms as Collett may fix and specify in the notice of sale to be given as hereinafter provided, or as may be required by law. 

        4.2    Notice
of any sale to be made under or by virtue of this Security Agreement shall state the time when and the place where the same is to be made, shall contain the
number of the shares to be sold, and shall state briefly the terms of the sale; and shall be given to the Freedom not less than ten (10) days prior to such sale or sales; and if such notice is
mailed by prepaid registered mail, return receipt requested, to the last office address of Freedom given to the Collett by Freedom, it shall be deemed duly given on the date of deposit in the mails
whether or not received by Freedom. 

        4.3    Any
sale to be made under the provisions hereof may be adjourned from time to time by announcement at the time and place appointed for such sale or for such adjourned
sale; and, except as 

2

 

otherwise provided by law, such sale may be made without further notice or publication at the time and place to which the same shall be so adjourned. 

        4.4    Upon
any sale or sales at public or private sale above proved for, Collett, his heirs, personal representatives and permitted assigns, may bid for and/or purchase the
whole or any part of such Shares free from any right of redemption, which is hereby waived and released. 

        4.5    In
case of any sale by Collett of any Shares on credit or for future delivery, the Shares sold may be retained by Collett until the selling price is paid by the
purchaser and Collett shall incur no liability in case of failure of the purchaser to take up and pay for the Shares so sold. In case of any such failure, the Shares may be sold again. 

        4.6    Upon
the completion of any sale or sales made hereunder or by virtue hereof, Collett shall deliver to the accepted purchaser or purchasers the Shares so sold in proper
form for transfer to such purchaser or purchasers, and shall execute and deliver such instruments, if any, as shall be necessary or appropriate to assign and transfer to such purchaser or purchasers
the Shares so sold. Collett is hereby irrevocably appointed the true and lawful attorney of Freedom in its name and stead or in the name of Collett, to make all necessary assignments, transfers and
deliveries of the Shares so sold and for that purpose Collett may execute all necessary instruments of assignment and transfer and may substitute one or more person with like power. Freedom hereby
ratifies all that its said attorney or substitute or substitutes shall lawfully do by virtue hereof. Nevertheless, Freedom, if requested in writing by Collett, shall ratify and confirm any such sale
or sales by executing and delivering to Collett, or to such purchaser or purchasers, all such instruments as may be advisable, in the judgment of Collett, for the purpose and as may be designated in
such request. 

        4.7    Any
such sale or sales made under or by virtue hereof, whether made under the power of sale herein granted or under or by virtue of statutory proceedings, shall operate
to divest all estate, right,
title, interest, claim or demand whatsoever, whether at law or in equity, of Freedom in and to the Shares so sold, and shall be a perpetual bar both at law and in equity against Freedom, its
successors and assigns, and against any and all persons claiming, or who may claim the same, or any part thereof, through or under the Freedom, its successors and assigns. 

        4.8    The
receipt by Collett for the purchase money paid at any such sale shall be a sufficient discharge therefor to any purchaser of the Shares, or any part thereof sold as
aforesaid; and no such purchaser or his representative or assigns, after paying such purchase money and receiving such receipt, shall be bound to see to the application of such purchase money, or
shall be answerable in any manner whatsoever for any loss, misapplication or non-application of any such purchase money or any part thereof, nor shall any such purchaser be bound to
inquire as to the necessity or expediency of any such sale. 

        4.9    The
purchase money, proceeds or avails of any such sale shall be applied as follows: 

        First: To the payment of the costs and expenses of such sale, including reasonable compensation to Collett, his agents, attorneys,
nominees and counsel, and of any statutory proceeding wherein the same may be made, and of all expenses, liabilities and advances reasonably made or incurred by the Collett, together with interest at
the rate of 6% per annum on all advances made by Collett. 

        Second: To the payment of the whole amount then due, owing or unpaid upon any indebtedness owed to Collett by Freedom under the
Indemnification Agreement and the Promissory Notes. 

        Third: The surplus, if any, shall be paid to Freedom, its successor or assigns as their interests may appear, or to whomever shall be
lawfully entitled to receive the same, or as any court of competent jurisdiction may direct. 

3

 

        4.10    No
remedy herein conferred upon or reserved to Collett is intended to be exclusive of any other remedy or remedies, and each and every such remedy shall be cumulative
and shall be in addition to every remedy given hereunder or now or hereafter existing at law or in equity or by statute. No delay or omission of Collett to exercise any right or power accruing upon
any event of default shall impair any such right or power or shall be construed to be a waiver of any such event of default or any acquiescence therein; and every power and remedy given by this
Security Agreement to Collett may be exercised from time to time and as often as may be deemed expedient by Collett. 

        5.    Satisfaction.    If, when Freedom has fully performed its responsibilities and obligations under the
Indemnification Agreement and paid all sums due Collett under the Promissory Notes, then and in that case all rights and interests hereby assigned shall revert to Freedom, its successors and assigns,
as their interests may appear, or to whomever shall be lawfully entitled to receive the same, and the right, title and interest of Collett therein shall thereupon cease, determine and become void, and
the Shares forthwith shall be transferred and delivered to Freedom, its successors and assigns, or to whomever shall be lawfully entitled to receive the same. 

 6.    Miscellaneous.  

        6.1    Freedom agrees to pay, or to reimburse Collett for the payment of, any out-of-pocket expenses reasonably incurred by
Collett under this Security Agreement and also agrees to pay, and to save Collett harmless, without limitation as to time, against any and all liabilities with respect to, all taxes which may be
payable in connection with the payment of dividends or other distributions made in respect of any of the Shares or otherwise in connection with any action contemplated by this Security Agreement. 

        6.2    This
Agreement constitutes the entire agreement between Freedom and Collett with respect to the subject matter herein, and all prior oral or written discussions or
agreements between the parties are deemed to have been merged into this Agreement. 

        6.3    This
Agreement may not be supplemented, altered, amended or modified except in writing signed by Freedom and Collett. 

        6.4    This
Agreement shall be governed by and construed in accordance with the Laws of the State of Indiana applicable to a contract executed and performable in such state
without regard to conflict of law principles. 

        6.5    This
Agreement is binding upon and inures to the benefit of the parties hereto and their respective successors, permitted assigns, heirs and personal representatives. 

        6.6    Neither
this Agreement nor any right hereunder or part hereof may be assigned by any party hereto without the prior written consent of the other party hereto. 

        6.7    This
Agreement may be executed simultaneously in two or more counterparts, each of which shall be deemed to be an original, but all of which together shall constitute
one and the same instrument. 

        6.8    This
Agreement shall be effective as of the 14th day of May 2002.

                         REPRESENTATIONS AND WARRANTIES

         3.1 REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company hereby
makes the following representations and warranties to each Purchaser, as of the
date of this Agreement that:

             (a) SUBSIDIARIES. The Company has no direct or indirect
Subsidiaries other than those listed in SCHEDULE 3.1(a). Except as disclosed in
SCHEDULE 3.1(a), the Company owns, directly or indirectly, all of the capital
stock of each Subsidiary free and clear of any and all Liens, and all the issued
and outstanding shares of capital stock of each Subsidiary are validly issued
and are fully paid, non-assessable and free of preemptive and similar rights. If
the Company has no Subsidiaries, then references in the Transaction Documents to
Subsidiaries will be disregarded.

             (b) ORGANIZATION AND QUALIFICATION. Each of the Company and each
Subsidiary is an entity duly incorporated or otherwise organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation or organization (as applicable), with the requisite power and
authority to own and use its properties and assets and to carry on its business
as currently conducted. Neither the Company nor any Subsidiary is in violation
of any of the provisions of its respective certificate or articles of
incorporation, bylaws or other

                                      -5-

<PAGE>

organizational or charter documents. Each of the Company and each Subsidiary is
duly qualified to conduct business and is in good standing as a foreign
corporation or other entity in each jurisdiction in which the nature of the
business conducted or property owned by it makes such qualification necessary,
except where the failure to be so qualified or in good standing, as the case may
be, would not, individually or in the aggregate, have or reasonably be expected
to result in (i) an adverse effect on the legality, validity or enforceability
of any Transaction Document, (ii) a material adverse effect on the results of
operations, assets, prospects, business or condition (financial or otherwise) of
the Company and the Subsidiaries, taken as a whole, or (iii) an inability of the
Company to perform on a timely basis its obligations under any Transaction
Document (any of (i), (ii) or (iii), a "MATERIAL ADVERSE EFFECT").

             (c) AUTHORIZATION; ENFORCEMENT. The Company has the requisite
corporate power and authority to enter into and to consummate the transactions
contemplated by each of the Transaction Documents and otherwise to carry out its
obligations thereunder. The execution and delivery of each of the Transaction
Documents by the Company and the consummation by it of the transactions
contemplated thereby have been duly authorized by all necessary corporate action
on the part of the Company and no further action is required by the Company in
connection therewith. Each Transaction Document has been (or upon delivery will
have been) duly executed by the Company and, when delivered in accordance with
the terms hereof, will constitute the valid and binding obligation of the
Company enforceable against the Company in accordance with its terms, 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.

             (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 thereby do not and will not (i) conflict with or
violate any provision of the Company's or any Subsidiary's certificate or
articles of incorporation, bylaws or other organizational or charter documents,
or (ii) conflict with, or constitute a default (or an event that with notice or
lapse of time or both would become a default) under, or give to others any
rights of termination, amendment, acceleration or cancellation (with or without
notice, lapse of time or both) of, any agreement, credit facility, debt or other
instrument (evidencing a Company or Subsidiary debt or otherwise) or other
understanding to which the Company or any Subsidiary is a party or by which any
property or asset of the Company or any Subsidiary is bound or affected, or
(iii) result in a violation of any law, rule, regulation, order, judgment,
injunction, decree or other restriction of any court or governmental authority
to which the Company or a Subsidiary is subject (including federal and state
securities laws and regulations) applicable to the Company or any of its
Subsidiaries, or by which any property or asset of the Company or a Subsidiary
is bound or affected; except in the case of each of clauses (ii) and (iii), such
as could not, individually or in the aggregate, have or reasonably be expected
to result in a Material Adverse Effect.

             (e) FILINGS, CONSENTS AND APPROVALS. The Company is not required to
obtain any consent, waiver, authorization or order of, give any notice to, or
make any filing or

                                      -6-

<PAGE>

registration with, any court or other federal, state, local or other
governmental authority or other Person in connection with the execution,
delivery and performance by the Company of the Transaction Documents where the
failure to so obtain would have or could reasonably be expected to result in a
Material Adverse Effect, other than: (i) the filing with the Commission of one
or more Registration Statements and Form D, (ii) the filing of any applicable
blue sky filings, and (iii) the application(s) to the Trading Market on which
the shares of Common Stock of the Company are currently traded for the listing
of the Shares and Warrant Shares for trading thereon in the time and manner
required thereby (collectively, the "REQUIRED APPROVALS").

             (f) ISSUANCE OF THE SECURITIES. The Securities have been duly
authorized and, when issued and paid for in accordance with the Transaction
Documents, will be duly and validly issued, fully paid and nonassessable, free
and clear of all Liens, except for those restrictions on the Securities
specified in the Transaction Documents. The Company has reserved from its duly
authorized capital stock the maximum number of shares of Common Stock issuable
pursuant to this Agreement and the Warrants in order to issue the full number of
Warrant Shares as are or may become issuable in accordance with the Warrants.

             (g) CAPITALIZATION. The number of shares and type of all
authorized, issued and outstanding capital stock of the Company is set forth in
SCHEDULE 3.1(g). Except as set forth in SCHEDULE 3.1(g), no securities of the
Company are entitled to preemptive or similar rights, and no Person has any
right of first refusal, preemptive right, right of participation, or any similar
right to participate in the transactions contemplated by the Transaction
Documents. Except as a result of the purchase and sale of the Securities and
except as disclosed in SCHEDULE 3.1(g), there are no outstanding options,
warrants, scrip rights to subscribe to, calls or commitments of any character
whatsoever relating to, or securities, rights or obligations convertible into or
exchangeable for, or giving any Person any right to subscribe for or acquire,
any shares of Common Stock, or contracts, commitments, understandings or
arrangements by which the Company or any Subsidiary is or may become bound to
issue additional shares of Common Stock, or securities or rights convertible or
exchangeable into shares of Common Stock. Except as set forth in SCHEDULE
3.1(g), the issue and sale of the Securities will not, immediately or with the
passage of time, obligate the Company to issue shares of Common Stock or other
securities to any Person (other than the Purchasers) and will not result in a
right of any holder of Company securities to adjust the exercise, conversion,
exchange or reset price under such securities.

             (h) SEC REPORTS; FINANCIAL STATEMENTS. The Company has filed all
reports required to be filed by it under the Securities Act and the Exchange
Act, including pursuant to Section 13(a) or 15(d) thereof, for the two years
preceding the date hereof (or such shorter period as the Company was required by

Agreement, the "DISCLOSURE MATERIALS") on a timely basis or has received a valid
extension of such time of filing and has filed any such SEC Reports prior to the

regulations of the Commission promulgated thereunder, and none of the SEC

they were made, not misleading. As of their respective dates, the financial

respects with applicable accounting requirements and the published rules and
regulations of the Commission with respect thereto as in effect at the time of

             (j) LITIGATION. Except as set forth in SCHEDULE 3.1(j) or as
otherwise disclosed in the SEC Reports, there is no Action which (i) adversely
affects or challenges the legality, validity or enforceability of any of the

unfavorable decision, individually or in the aggregate, have or reasonably be
expected to result in a Material Adverse Effect. Neither the Company nor any

violation has been waived), (ii) is in violation of any order of any court,
arbitrator or governmental body, or (iii) is or has been in violation of any

all certificates, authorizations and permits issued by the appropriate federal,
state, local or foreign regulatory authorities necessary to conduct their
respective businesses as described in the SEC Reports, except where the failure
to possess such permits would not, individually or in the aggregate, have or
reasonably be expected to result in a Material Adverse Effect ("MATERIAL
PERMITS"), and neither the Company nor any Subsidiary has received any notice of
proceedings relating to the revocation or modification of any Material Permit.

             (n) PATENTS AND TRADEMARKS. Except as set forth on SCHEDULE 3.1(j),

patent applications, trademarks, trademark applications, service marks, trade
names, copyrights, licenses and other similar rights that are necessary or

(collectively, the "INTELLECTUAL PROPERTY RIGHTS"). Neither the Company nor any
Subsidiary has received a written notice that the Intellectual Property Rights
used by the Company or any Subsidiary violates or infringes upon the rights of
any Person. Except as set forth in the SEC Reports, to the knowledge of the
Company, all such Intellectual Property Rights are enforceable and there is no
existing infringement by another Person of any of the Intellectual Property
Rights.

             (o) TRANSACTIONS WITH AFFILIATES AND EMPLOYEES. Except as set forth
on SCHEDULE 3.1(o) and in the SEC Reports, none of the officers or directors of
the Company and, to the knowledge of the Company, none of the employees of the

<PAGE>

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

             (p) INTERNAL ACCOUNTING CONTROLS. The Company and the Subsidiaries
maintain a system of internal accounting controls sufficient 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.

             (q) SOLVENCY. Based on the financial condition of the Company as of
the Closing Date, (i) the Company's fair saleable value of its assets exceeds
the amount that will be required to be paid on or in respect of the Company's
existing debts and other liabilities (including known contingent liabilities) as
they mature; (ii) the Company's assets do not constitute unreasonably small
capital to carry on its business for the current fiscal year as now conducted
and as proposed to be conducted including its capital needs taking into account
the particular capital requirements of the business conducted by the Company,
and projected capital requirements and capital availability thereof; and (iii)
the current cash flow of the Company, together with the proceeds the Company
would receive, were it to liquidate all of its assets, after taking into account
all anticipated uses of the cash, would be sufficient to pay all amounts on or
in respect of its debt when such amounts are required to be paid. The Company
does not intend to incur debts beyond its ability to pay such debts as they
mature (taking into account the timing and amounts of cash to be payable on or
in respect of its debt).

             (r) CERTAIN FEES. Except as described in SCHEDULE 3.1(r), no
brokerage or finder's fees or commissions are or will be payable by the Company
to any broker, financial advisor or consultant, finder, placement agent,
investment banker, bank or other Person with respect to the transactions
contemplated by this Agreement. The Purchasers shall have no obligation with
respect to any fees or with respect to any claims made by or on behalf of other
Persons for fees of a type contemplated in this Section that may be due in
connection with the transactions contemplated by this Agreement.

             (s) CERTAIN REGISTRATION MATTERS. Assuming the accuracy of the
Purchasers' representations and warranties set forth in Section 3.2(b)-(f), no
registration under the Securities Act is required for the offer and sale of the
Shares and Warrant Shares by the Company to the Purchasers as contemplated by
the Transaction Documents. The Company is eligible to register the resale of its
Common Stock for resale by the Purchasers under Form S-3 promulgated under the
Securities Act. Except as described in SCHEDULE 3.1(s), the Company has not
granted or agreed to grant to any Person any rights (including "piggy-back"
registration rights) to have any

                                      -10-

<PAGE>

securities of the Company registered with the Commission or any other
governmental authority that have not been satisfied.

             (t) LISTING AND MAINTENANCE REQUIREMENTS. The Company has not, in
the two years preceding the date hereof, received notice (written or oral) from
any Trading Market on which the Common Stock is or has been listed or quoted to
the effect that the Company is not in compliance with the listing or maintenance
requirements of such Trading Market. The Company is, and has no reason to
believe that it will not in the foreseeable future continue to be, in compliance
with all such listing and maintenance requirements of the Trading Market. The
issuance and sale of the Securities hereunder do not contravene the rules and
regulations of the Trading Market and no shareholder approval is required for
the Company to fulfill its obligations under the Transaction Documents,
including issuing and delivering to the Purchasers the maximum number of Shares
and Warrant Shares contemplated by this Agreement.

             (u) INVESTMENT COMPANY. The Company is not, and is not an Affiliate
of, an "investment company" within the meaning of the Investment Company Act of
1940, as amended.

             (v) APPLICATION OF TAKEOVER PROTECTIONS. Subject to the accuracy of
the representations and warranties of the Purchasers set forth in Section 3.2(i)
hereof, the Company has taken all necessary action, if any, in order to render
inapplicable any control share acquisition, business combination, poison pill
(including any distribution under a rights agreement) or other similar
anti-takeover provision under the Company's Certificate of Incorporation (or
similar charter documents) or the laws of its state of incorporation that is or
could become applicable to the Purchasers solely as a result of the Purchasers
and the Company fulfilling their obligations or exercising their rights under
the Transaction Documents, including without limitation the Company's issuance
of the Securities and the Purchasers' ownership of the Securities.

             (w) DISCLOSURE. The Company confirms that neither the Company nor
any other Person acting on its behalf has provided any of the Purchasers or
their agents or counsel with any information that the Company believes
constitutes material, non-public information. The Company understands and
confirms that the Purchasers will rely on the foregoing representations and
covenants in effecting transactions in securities of the Company. All
disclosures provided to the Purchasers regarding the Company, its business and
the transactions contemplated hereby, furnished by or on behalf of the Company
are true and correct and do not contain any untrue statement of a material fact
or omit to state any material fact necessary in order to make the statements
made therein, in light of the circumstances under which they were made, not
misleading.

         3.2 REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS. Each Purchaser
hereby, for itself and for no other Purchaser, represents and warrants to the
Company as follows:

             (a) ORGANIZATION; AUTHORITY. Such Purchaser is an entity duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization with

                                      -11-

<PAGE>

the requisite corporate or partnership power and authority to enter into and to
consummate the transactions contemplated by the applicable Transaction Documents
and otherwise to carry out its obligations thereunder. The execution, delivery
and performance by such Purchaser of the transactions contemplated by this
Agreement has been duly authorized by all necessary corporate or partnership
action on the part of such Purchaser. Each of this Agreement and the
Registration Rights Agreement has been duly executed by such Purchaser, and when
delivered by such Purchaser in accordance with terms hereof, will constitute the
valid and legally binding obligation of such Purchaser, enforceable against it
in accordance with its terms.

             (b) INVESTMENT INTENT. Such Purchaser is acquiring the Securities
as principal for its own account for investment purposes only and not with a
view to or for distributing or reselling such Securities or any part thereof,
without prejudice, however, to such Purchaser's right at all times to sell or
otherwise dispose of all or any part of such Securities in compliance with
applicable federal and state securities laws. Nothing contained herein shall be
deemed a representation or warranty by such Purchaser to hold the Securities for
any period of time. Such Purchaser is acquiring the Securities hereunder in the
ordinary course of its business. Such Purchaser does not have any agreement or
understanding, directly or indirectly, with any Person to distribute any of the
Securities.

             (c) PURCHASER STATUS. At the time such Purchaser was offered the
Securities, it was, and at the date hereof it is, and on each date on which it
exercises the Warrants it will be, an "accredited investor" as defined in Rule
501(a) under the Securities Act. Such Purchaser is not a registered
broker-dealer under Section 15 of the Exchange Act.

             (d) EXPERIENCE OF SUCH PURCHASER. Such Purchaser, either alone or
together with its representatives, has such knowledge, sophistication and
experience in business and financial matters so as to be capable of evaluating
the merits and risks of the prospective investment in the Securities, and has so
evaluated the merits and risks of such investment. Such Purchaser is able to
bear the economic risk of an investment in the Securities and may have to do so
indefinitely and, at the present time, is able to afford a complete loss of such
investment.

             (e) GENERAL SOLICITATION. Such Purchaser is not purchasing the
Securities as a result of any advertisement, article, notice or other
communication regarding the Securities published in any newspaper, magazine or
similar media or broadcast over television or radio or presented at any seminar
or any other general solicitation or general advertisement.

             (f) ACCESS TO INFORMATION. Such Purchaser acknowledges that it has
reviewed the Disclosure Materials and has been afforded (i) the opportunity to
ask such questions as it has deemed necessary of, and to receive answers from,
representatives of the Company concerning the terms and conditions of the
offering of the Shares and the merits and risks of investing in the Securities;
(ii) access to information about the Company and the Subsidiaries and their
respective financial condition, results of operations, business, properties,
management and prospects sufficient to enable it to evaluate its investment; and
(iii) the opportunity to obtain such additional information that the Company
possesses or can acquire without unreasonable effort or

                                      -12-

<PAGE>

expense that is necessary to make an informed investment decision with respect
to the investment. Neither such inquiries nor any other investigation conducted
by or on behalf of such Purchaser or its representatives or counsel shall
modify, amend or affect such Purchaser's right to rely on the truth, accuracy
and completeness of the Disclosure Materials and the Company's representations
and warranties contained in the Transaction Documents.

             (g) PLACE OF BUSINESS. The residence or principal place of business
of such Purchaser is set forth on such Purchaser's signature page to this
Agreement.

             (h) RELIANCE. Such Purchaser understands that the Company is
relying on the representations and warranties of such Purchaser hereunder to
establish an exemption from registration under federal and state securities
laws.

             (i) BENEFICIAL OWNERSHIP. Upon the consummation of the transactions
contemplated by this Agreement, such Purchaser will not become a Beneficial
Owner of 15% or more of the shares of Common Stock outstanding as of the date of
this Agreement.

         The Company acknowledges and agrees that each Purchaser does not make
or has not made any representations or warranties with respect to the
transactions contemplated hereby other than those specifically set forth in this
Section 3.2.

                                   ARTICLE IV.
                         OTHER AGREEMENTS OF THE PARTIES

         4.1 TRANSFER RESTRICTIONS (a) Securities may only be disposed of in
compliance with state and federal securities laws. In connection with any
transfer of the Securities other than pursuant to an effective registration
statement, to the Company, to an Affiliate of a Purchaser or in connection with
a pledge as contemplated in Section 4.1(b), the Company may require the
transferor thereof to provide to the Company a written opinion of counsel
selected by the transferor, the form and substance of which opinion shall be
reasonably satisfactory to the Company, to the effect that such transfer does
not require registration of such transferred Securities under the Securities
Act.

             (b) Certificates evidencing the Securities will contain the
following legend, so long as is required by this SECTION 4.1(b):

             [NEITHER] THESE SECURITIES [NOR THE SECURITIES ISSUABLE UPON
             EXERCISE OF THESE SECURITIES] HAVE [NOT] BEEN REGISTERED WITH THE
             SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF
             ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE
             SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
             ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
             EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR
             PURSUANT TO AN AVAILABLE EXEMPTION

                                      -13-

<PAGE>

             FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
             REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH
             APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A WRITTEN LEGAL
             OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE
             OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THESE
             SECURITIES AND THE SECURITIES ISSUABLE UPON EXERCISE OF THESE
             SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN
             ACCOUNT OR OTHER LOAN SECURED BY SUCH SECURITIES.

             The Company acknowledges and agrees that a Purchaser may from time
to time pledge pursuant to a bona fide margin agreement or grant a security
interest in some or all of the Securities and, if required under the terms of
such arrangement, such Purchaser may transfer pledged or secured Securities to
the pledgees or secured parties. Such a pledge or transfer would not be subject
to approval or consent of the Company and no legal opinion of legal counsel of
the pledgee, secured party or pledgor shall be required in connection therewith.
Further, no notice shall be required of such pledge. At the appropriate
Purchaser's expense, the Company will execute and deliver such reasonable
documentation as a pledgee or secured party of Securities may reasonably request
in connection with a pledge or transfer of the Securities, including the
preparation and filing of any required prospectus supplement under Rule
424(b)(3) of the Securities Act or other applicable provision of the Securities
Act to appropriately amend the list of Selling Stockholders thereunder.

             (c) Certificates evidencing the Shares and Warrant Shares shall not
contain any legend (including the legend set forth in Section 4.1(b)): (i) while
a registration statement (including the Registration Statement) covering the
resale of such Shares and Warrant Shares is effective under the Securities Act,
or (ii) following any sale of such Shares or Warrant Shares pursuant to Rule
144, or (iii) if such Shares or Warrant Shares are eligible for sale under Rule
144(k), or (iv) if such legend is not required under applicable requirements of
the Securities Act (including judicial interpretations and pronouncements issued
by the Staff of the Commission). The Company shall cause its counsel to issue
the legal opinion included in the Transfer Agent Instructions to the Company's
transfer agent on the Effective Date. Following the Effective Date or at such
earlier time as a legend is no longer required for the Shares and Warrant Shares
under this Section 4.1(c), the Company will, no later than three Trading Days
following the delivery by a Purchaser to the Company or the Company's transfer
agent of a certificate representing Shares or Warrant Shares containing a
restrictive legend, deliver or cause to be delivered to such Purchaser a
certificate representing such Shares or Warrant Shares that is free from all
restrictive and other legends. The Company may not make any notation on its
records or give instructions to any transfer agent of the Company that enlarge
the restrictions on transfer set forth in this Section.

         4.2 FURNISHING OF INFORMATION. As long as any Purchaser owns the
Securities, the Company covenants to timely file (or obtain extensions in
respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof

                                      -14-

<PAGE>

pursuant to the Exchange Act. Upon the request of any such Person, the Company
shall deliver to such Person a written certification of a duly authorized
officer as to whether it has complied with the preceding sentence. As long as
any Purchaser owns Securities, if the Company is not required to file reports
pursuant to such laws, it will prepare and furnish to the Purchasers and make
publicly available in accordance with Rule 144(c) such information as is
required for the Purchasers to sell the Shares and Warrant Shares under Rule
144. The Company further covenants that it will take such further action as any
holder of Securities may reasonably request, all to the extent required from
time to time to enable such Person to sell such Shares and Warrant Shares
without registration under the Securities Act within the limitation of the
exemptions provided by Rule 144.

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

         4.4 SECURITIES LAWS DISCLOSURE; PUBLICITY. The Company shall (i) on the
Closing Date (x) issue a press release reasonably acceptable to the Purchasers
disclosing the transactions contemplated hereby and (y) file a Current Report on
Form 8-K disclosing the transactions contemplated hereby and (ii) make such
other filings and notices in the manner and time required by the Commission.
Notwithstanding the foregoing, the Company shall not publicly disclose the name
of any Purchaser, or include the name of any Purchaser in any filing with the
Commission or any regulatory agency or Trading Market, without the prior written
consent of such Purchaser, except to the extent such disclosure is required by
law or Trading Market regulations, in which case the Company shall provide the
Purchasers with prior notice of such disclosure.

         4.5 INDEMNIFICATION OF PURCHASERS. The Company will indemnify and hold
the Purchasers and their directors, officers, shareholders, partners, employees
and agents (each, a "PURCHASER PARTY") harmless from any and all losses,
liabilities, obligations, claims, contingencies, damages, costs and expenses,
including all judgments, amounts paid in settlements, court costs and reasonable
attorneys' fees and costs of investigation (collectively, "LOSSES") that any
such Purchaser Party may suffer or incur as a result of or relating to (a) any
misrepresentation, breach or inaccuracy, or any allegation by a third party
that, if true, would constitute a breach or inaccuracy, of any of the
representations, warranties, covenants or agreements made by the Company in any
Transaction Document; or (b) any Action brought or made against such Purchaser
Party and solely arising out of or resulting from the execution, delivery,
performance or enforcement of this Agreement or any of the other Transaction
Documents. In addition to the indemnity contained herein, the Company will
reimburse each Purchaser Party for its reasonable legal and other expenses
(including the cost of any investigation, preparation and travel in connection
therewith) incurred in connection therewith, as such expenses are incurred.

                                      -15-

<PAGE>

         4.6 SHAREHOLDERS RIGHTS PLAN. No claim will be made or enforced by the
Company or any other Person that any Purchaser is an "Acquiring Person" under
any shareholders rights plan or similar plan or arrangement in effect or
hereafter adopted by the Company, or that any Purchaser could be deemed to
trigger the provisions of any such plan or arrangement, solely by virtue of
receiving the Securities under the Transaction Documents or under any other
agreement between the Company and the Purchasers.

         4.7 NON-PUBLIC INFORMATION. The Company covenants and agrees that
neither it nor any other Person acting on its behalf will provide any Purchaser
or its agents or counsel with any information that the Company believes
constitutes material non-public information, unless prior thereto such Purchaser
shall have executed a written agreement regarding the confidentiality and use of
such information. The Company understands and confirms that each Purchaser shall
be relying on the foregoing representations in effecting transactions in
securities of the Company.

         4.8 USE OF PROCEEDS. The Company shall use the net proceeds from the
sale of the Securities hereunder for general corporate purposes, including
repayment of the Company's line of credit, funding working capital, capital
expenditures and investments in new product development.

         4.9 RESTRICTIONS ON SALE OF SECURITIES. Each Purchaser agrees that it
will not, prior to the Effective Date, if then prohibited by law, enter into any
sales of Shares or Warrant Shares, nor will such Purchaser engage in any
hedging, short selling or other transaction which is designed to or result in a
sale of Shares or Warrant Shares by such Purchaser prior to such date.

                                   ARTICLE V.
                                  MISCELLANEOUS

         5.1 FEES AND EXPENSES. The Company has agreed to reimburse $35,000 to
the Purchasers as reimbursement for the Purchasers' legal and other fees and
expenses incurred to prepare and negotiate the Transaction Documents.
Accordingly, in lieu of the foregoing payments, the Company, on the Closing
Date, will direct that the aggregate amount that the Purchasers are to pay for
the Securities at the Closing, be reduced by $35,000 and paid to Purchaser
Counsel and upon request by the Company, Purchaser Counsel shall provide a copy
of its invoice to its client to verify such fees and expenses. Except as
specified in the immediately preceding sentence and as contemplated in the
Registration Rights Agreement, each party shall pay the fees and expenses of its
advisers, counsel, accountants and other experts, if any, and all other expenses
incurred by such party incident to the negotiation, preparation, execution,
delivery and performance of this Agreement. The Company shall pay all stamp and
other taxes and duties levied in connection with the sale of the Securities.

         5.2 ENTIRE AGREEMENT. The Transaction Documents, together with the
Exhibits and Schedules thereto, contain the entire understanding of the parties
with respect to the subject matter hereof and supersede all prior agreements and
understandings, oral or written, with respect to such matters, which the parties
acknowledge have been merged into such documents, exhibits and schedules.

         5.4 AMENDMENTS; WAIVERS. No provision of this Agreement may be waived
or amended except in a written instrument signed, in the case of an amendment,
by the Company and Purchasers then holding a majority of the voting power
represented by the Securities purchased hereunder, assuming the exercise in full
of all of the Warrants. No waiver of any default with respect to any provision,
condition or requirement of this Agreement shall be deemed to be a continuing
waiver in the future or a waiver of any subsequent default or a waiver of any
other provision, condition or requirement hereof, nor shall any delay or

         5.5 CONSTRUCTION. The headings herein are for convenience only, do not

<PAGE>

of proof shall arise favoring or disfavoring any party by virtue of the
authorship of any provisions of this Agreement or any of the Transaction
Documents.

         5.6 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and
inure to the benefit of the parties and their successors and permitted assigns.
Except in the event of a sale of all or substantially all of the assets,
business or capital stock of the Company, the Company may not assign this
Agreement or any rights or obligations hereunder without the prior written
consent of the Purchasers. Any Purchaser may assign any or all of its rights
under this Agreement to any Person to whom such Purchaser assigns or transfers
any Securities, provided such transferee agrees in writing to be bound, with
respect to the transferred Securities, by the provisions hereof that apply to
the "Purchasers."

         5.7 NO THIRD-PARTY BENEFICIARIES. This Agreement is intended for the
benefit of the parties hereto and their respective successors and permitted
assigns and is not for the benefit of, nor may any provision hereof be enforced
by, any other Person, except as otherwise set forth in Section 4.6.

         5.8 GOVERNING LAW. All questions concerning the construction, validity,
enforcement and interpretation of this Agreement shall be governed by and
construed and enforced in accordance with the internal laws of the State of New
York, without regard to the principles of conflicts of law thereof. Each party
agrees that all Proceedings concerning the interpretations, enforcement and
defense of the transactions contemplated by this Agreement and any other
Transaction Documents (whether brought against a party hereto or its respective
affiliates, directors, officers, stockholders, employees or agents) shall be
commenced exclusively in the state and federal courts sitting in the City of New
York, Borough of Manhattan. Each party hereto hereby irrevocably submits to the
exclusive jurisdiction of the state and federal courts sitting in the City of
New York, Borough of Manhattan for the adjudication of any dispute hereunder or
in connection herewith or with any transaction contemplated hereby or discussed
herein (including with respect to the enforcement of the any of the Transaction
Documents), and hereby irrevocably waives, and agrees not to assert in any
Proceeding, any claim that it is not personally subject to the jurisdiction of
any such court, or that such Proceeding is improper. Each party hereto hereby
irrevocably waives personal service of process and consents to process being
served in any such Proceeding by mailing a copy thereof via registered or
certified mail or overnight delivery (with evidence of delivery) to such party
at the address in effect for notices to it under this Agreement and agrees that
such service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law. Each party hereto hereby
irrevocably waives, to the fullest extent permitted by applicable law, any and
all right to trial by jury in any legal proceeding arising out of or relating to
this Agreement or the transactions contemplated hereby. If either party shall

                                      -18-

         5.9 SURVIVAL. The representations and warranties contained herein shall
survive the Closing and the delivery of the Shares and Warrants, as applicable
for a two year period following the Closing.

         5.10 EXECUTION. This Agreement may be executed in two or more
counterparts, all of which when taken together shall be considered one and the
same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party, it being understood that both
parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission, such signature shall create a valid and
binding obligation of the party executing (or on whose behalf such signature is
executed) with the same force and effect as if such facsimile signature page
were an original thereof.

         5.11 SEVERABILITY. If any provision of this Agreement is held to be
invalid or unenforceable in any respect, the validity and enforceability of the
remaining terms and provisions of this Agreement shall not in any way be
affected or impaired thereby and the parties will attempt to agree upon a valid
and enforceable provision that is a reasonable substitute therefor, and upon so
agreeing, shall incorporate such substitute provision in this Agreement.

         5.12 RESCISSION AND WITHDRAWAL RIGHT. Notwithstanding anything to the
contrary contained in (and without limiting any similar provisions of) the
Transaction Documents, whenever any Purchaser exercises a right, election,
demand or option under a Transaction Document and the Company does not timely
perform its related obligations within the periods therein provided, then such
Purchaser may rescind or withdraw, in its sole discretion from time to time upon
written notice to the Company, any relevant notice, demand or election in whole
or in part without prejudice to its future actions and rights.

         5.13 REPLACEMENT OF SECURITIES. If any certificate or instrument
evidencing any Securities is mutilated, lost, stolen or destroyed, the Company
shall issue or cause to be issued in exchange and substitution for and upon
cancellation thereof, or in lieu of and substitution therefor, a new certificate
or instrument, but only upon receipt of evidence reasonably satisfactory to the
Company of such loss, theft or destruction and customary and reasonable
indemnity, if requested. The applicants for a new certificate or instrument
under such circumstances shall also pay any reasonable third-party costs
associated with the issuance of such replacement Securities.

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

         5.15 INDEPENDENT NATURE OF PURCHASERS' OBLIGATIONS AND RIGHTS. The
obligations of each Purchaser under any Transaction Document are several and not
joint with the obligations of

                                      -19-

<PAGE>

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