                        COMMON STOCK PURCHASE AGREEMENT

     This COMMON STOCK PURCHASE AGREEMENT (this "Agreement") is dated as of
August 14, 2002 by and between Lumenon Innovative Lightwave Technology, Inc., a
Delaware corporation (the "Company") and Crossover Ventures, Inc. (the

     WHEREAS, the parties desire that, upon the terms and subject to the

     WHEREAS, such investments will be made by the Purchaser as statutory
underwriter of a registered indirect primary offering of such Common Stock by
the Company.

     NOW, THEREFORE, in consideration of the foregoing premises, and the
promises and covenants herein contained, the receipt and sufficiency of which
are hereby acknowledged by the parties hereto, the parties, intending to be
legally bound, hereby agree as follows:

                                   ARTICLE 1

                       PURCHASE AND SALE OF COMMON STOCK

     SECTION 1.1.  Purchase and Sale of Stock.  Upon the terms and subject to
the conditions of this Agreement, the Company may sell and issue to the
Purchaser and the Purchaser shall be obligated to purchase from the Company, up
to an aggregate of $14,000,000 worth of shares of Common Stock (the "Commitment

     SECTION 1.2.  Purchase Price and Initial Closing.  In consideration of and
in express reliance upon the representations, warranties, covenants, terms and
conditions of this Agreement, the Company agrees to issue and sell to the

place at the offices of Feldman Weinstein LLP, 420 Lexington Avenue, Suite 2620,
New York, New York 10170 (i) at 10:00 a.m. local time on August 14, 2002, or
(ii) at such other time and place or on such date as the Purchaser and the
Company may agree upon (the "Initial Closing Date"). Each party shall deliver
all documents, instruments and writings required to be delivered by such party
pursuant to this Agreement at or prior to the Initial Closing.

                                   ARTICLE 2

                         REPRESENTATIONS AND WARRANTIES

     SECTION 2.1.  Representation and Warranties of the Company.  The Company
hereby makes the following representations and warranties to the Purchaser, in
each case except as set forth in the SEC Documents, in the Disclosure Letter
prepared by the Company and delivered concurrently herewith or as contemplated
by this Agreement:

        (a) Organization, Good Standing and Power. The Company is a corporation
     duly incorporated, validly existing and in good standing under the laws of
     Delaware and has all requisite corporate authority to own, lease and
     operate its properties and assets and to carry on its business as now being
     conducted, except where the failure to be so incorporated or in good
     standing or to have such corporate authority would not have a Material
     Adverse Effect. The Company does not have any subsidiaries and does not own
     or control more than fifty percent (50%) of any other business entity. The
     Company is duly qualified to do business and is in good standing as a
     foreign corporation in each jurisdiction in which the nature of

                                       1
<PAGE>

     the business conducted or property owned by it makes such qualification
     necessary, other than those jurisdictions in which the failure so to
     qualify would not have a Material Adverse Effect.

        (b) Authorization, Enforcement. (i) The Company has the requisite
     corporate power and corporate authority to enter into and perform its
     obligations under the Transaction Documents and to issue the Draw Down
     Shares, (ii) the execution and delivery of the Transaction Documents by the
     Company and the consummation by it of the transactions contemplated hereby
     and thereby have been duly authorized by all necessary corporate action and
     no further consent or authorization of the Company or its Board of
     Directors or stockholders is required, and (iii) the Transaction Documents
     have been duly executed and delivered by the Company and shall constitute
     valid and binding obligations of the Company enforceable against the
     Company in accordance with their terms, except as such enforceability may
     be limited by applicable bankruptcy, insolvency, reorganization, fraudulent
     transfer, moratorium, liquidation, conservatorship, receivership or similar
     laws relating to, or affecting generally the enforcement of, creditors'
     rights and remedies or by other equitable principles of general
     application.

        (c) Capitalization. The authorized capital stock of the Company consists
     of 100,000,000 shares of Common Stock of which 40,984,375 shares were
     issued and outstanding as of July 15, 2002 and 5,000,000 preferred shares,
     none of which are issued and outstanding. All of the outstanding shares of
     the Common Stock have been duly and validly authorized and are fully paid
     and non-assessable. No shares of Common Stock are entitled to preemptive
     rights or registration rights and there are no outstanding options,
     warrants, scrip, rights to subscribe to, calls or commitments of any
     character whatsoever relating to, or securities or rights convertible into,
     any shares of capital stock of the Company. Furthermore, there are no
     contracts, commitments, understandings, or arrangements by which the
     Company is bound to issue additional shares of the capital stock of the
     Company or options, securities or rights convertible into shares of Common
     Stock. The Company is not a party to any agreement granting registration
     rights to any person with respect to any of its equity or debt securities.
     The Company is not a party to, and it has no knowledge of, any agreement
     restricting the voting or transfer of any shares of the capital stock of
     the Company. The offer and sale of all capital stock, convertible
     securities, rights, warrants, or options of the Company issued prior to the
     Initial Closing complied in all material respects with all applicable
     federal and state securities laws, and no stockholder has a right of
     rescission or damages with respect thereto which would have a Material
     Adverse Effect. The Company has made available to the Purchaser true and
     correct copies of the Company's certificate of incorporation as in effect
     on the date hereof (the "Charter"), and the Company's bylaws as in effect
     on the date hereof (the "Bylaws"). The Company has not received any notice
     from the Principal Market questioning or threatening the continued
     inclusion of the Common Stock on such market.

        (d) Issuance of Shares. The Warrant Shares to be issued upon exercise of
     the Initial Warrant (the "Initial Warrant Shares") have been duly
     authorized by all necessary corporate action and, when paid for and issued
     in accordance with the terms hereof and the Initial Warrant, the Initial
     Warrant Shares shall be validly issued and outstanding, fully paid and
     non-assessable, and the Purchaser shall be entitled to all rights accorded
     to a holder of Common Stock, when the Initial Warrant is exercised in
     accordance with its terms.

        (e) No Conflicts. The execution, delivery and performance of this
     Agreement by the Company and the consummation by the Company of the
     transactions contemplated herein do not and will not (i) violate any
     provision of the Company's Charter or Bylaws, (ii) conflict with, or
     constitute a default (or an event which with notice or lapse of time or
     both would become a default) under, or give to others any rights of
     termination, amendment, acceleration or cancellation of, any agreement,
     mortgage, deed of trust, indenture, note, bond, license, lease agreement,
     instrument or obligation to which the Company is a party, (iii) create or
     impose a lien, charge or encumbrance on any property of the Company under
     any agreement or any commitment to which the Company is a party or by which
     the Company is bound or by which any of its respective properties or assets
     are bound, or (iv) result in a violation of any federal, state or local
     statute, rule, regulation, order, judgment or decree (including any federal
     or 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 any
     of its subsidiaries are bound, except, in all cases, for such conflicts,
     defaults,
                                       2
<PAGE>

     termination, amendments, accelerations, cancellations and violations as
     would not, individually or in the aggregate, have a Material Adverse
     Effect. No consent, authorization or order of, or make any filing or
     registration with, any court or governmental agency is required by the
     Company in order for it to execute, deliver or perform any of its
     obligations under this Agreement, or issue and sell the Shares in
     accordance with the terms hereof (other than any filings which may be
     required to be made by the Company with the SEC, the Nasdaq Stock Market,
     Inc. or state securities administrators subsequent to the Initial Closing
     and any registration statement which may be filed pursuant hereto and such
     consents, authorizations, orders or filings which, if not obtained or made,
     would not be reasonably likely to have a Material Adverse Effect);
     provided, however, that for purpose of the representations made in this
     sentence, the Company is assuming and relying upon the accuracy of the
     relevant representations and agreements of the Purchaser herein.

        (f) SEC Documents, Financial Statements. The Common Stock is registered
     pursuant to Section 12(g) of the Exchange Act, and 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, including material filed pursuant to
     Section 13(a) or 15(d) of the Exchange Act. The Company has not provided to
     the Purchaser any information which, according to applicable law, rule or
     regulation, should have been disclosed publicly by the Company but which
     has not been so disclosed, other than with respect to the transactions
     contemplated by this Agreement. As of their respective filing dates, the
     SEC Documents complied in all material respects with the applicable
     requirements of the Exchange Act or the Securities Act, as applicable, and
     the rules and regulations of the SEC promulgated thereunder applicable to
     such documents, and, as of their respective filing dates after giving
     effect to the information disclosed and incorporated by reference therein,
     none of the SEC Documents contained any untrue statement of a material fact
     or omitted to state a material fact required to be stated therein or
     necessary in order to make the statements therein, in light of the
     circumstances under which they were made, not misleading. As of their
     respective dates, the financial statements of the Company included in the
     SEC Documents complied as to form in all material respects with applicable
     accounting requirements under GAAP and the published rules and regulations
     of the SEC. Such financial statements have been prepared in accordance with
     GAAP applied on a consistent basis during the periods involved (except (i)
     as may be otherwise indicated in such financial statements or the notes
     thereto or (ii) in the case of unaudited interim statements, except as may
     be permitted by the SEC on Form 10-Q under the Exchange Act), and fairly
     present in all material respects the consolidated financial position of the
     Company and its subsidiaries as of the dates thereof and the consolidated
     results of operations and cash flows for the periods then ended (subject,
     in the case of unaudited statements, to normal year-end audit adjustments).

        (g) Subsidiaries. The SEC Documents set forth each subsidiary of the
     Company, showing the jurisdiction of its incorporation or organization and
     showing the percentage of the Company's ownership of the outstanding stock
     or other interests of such subsidiary. For the purposes of this Agreement,
     "subsidiary" shall mean any corporation or other entity of which at least a
     majority of the securities or other ownership interests having ordinary
     voting power (absolutely or contingently) for the election of directors or
     other persons performing similar functions are at the time owned directly
     or indirectly by the Company and/or any of its other subsidiaries. All of
     the issued and outstanding shares of capital stock of each subsidiary have
     been duly authorized and validly issued, and are fully paid and
     non-assessable. Neither the Company nor any subsidiary is subject to any
     obligation (contingent or otherwise) to repurchase or otherwise acquire or
     retire any shares of the capital stock of any subsidiary or any convertible
     securities, rights, warrants or options of the type described in the
     preceding sentence.

        (h) No Material Adverse Effect. Since March 31, 2002, no change, event,
     circumstance, development or effect that would have a Material Adverse
     Effect has occurred with respect to the Company.

        (i) No Undisclosed Liabilities. Since March 31, 2002, neither the
     Company nor any of its subsidiaries has incurred any liabilities,
     obligations, claims or losses (whether liquidated or unliquidated, secured
     or unsecured, absolute, accrued, contingent or otherwise) that would be
     required to be disclosed on a balance sheet of the Company or any
     subsidiary (including the notes thereto) in conformity with

                                       3
<PAGE>

     GAAP or which would be required to be disclosed in the SEC Documents, other
     than those incurred in the ordinary course of the Company's or its
     subsidiaries' respective businesses since such date and which, individually
     or in the aggregate, do not or would not have a Material Adverse Effect.

        (j) No Undisclosed Events or Circumstances. Since March 31, 2002, no
     event or circumstance has occurred or exists with respect to the Company or
     its businesses, properties, operations or financial condition, that, under
     applicable law, rule or regulation, requires public disclosure or
     announcement prior to the date hereof by the Company but which has not been
     so publicly announced or disclosed in the SEC Documents and which
     individually or in the aggregate, do not or would not have a Material
     Adverse Effect.

        (k) Indebtedness. The SEC Documents or the Disclosure Letter sets forth
     as of the date hereof all outstanding secured and unsecured Indebtedness of
     the Company or any subsidiary, or for which the Company or any subsidiary
     has commitments. For the purposes of this Agreement, "Indebtedness" shall
     mean (A) any liabilities for borrowed money or amounts owed in excess of
     $500,000 (other than trade accounts payable incurred in the ordinary course
     of business), (B) all guaranties, endorsements and contingent obligations
     in respect of Indebtedness of others, whether or not the same are or should
     be reflected in the Company's balance sheet (or the notes thereto), except
     guaranties by endorsement of negotiable instruments for deposit or
     collection or similar transactions in the ordinary course of business; and
     (C) the present value of any lease payments in excess of $500,000 due under
     leases required to be capitalized in accordance with GAAP. Neither the
     Company nor any subsidiary is in default with respect to any Indebtedness.

        (l) Title to Assets. Each of the Company and the subsidiaries has good
     and marketable title to all of its real and personal property reflected in
     the SEC Documents, free of any mortgages, pledges, charges, liens, security
     interests or other encumbrances, except for those that do not have a
     Material Adverse Effect. All said leases with respect to real property
     leased by the Company and each of its subsidiaries as set forth in the SEC
     Documents are valid and subsisting and in full force and effect.

        (m) Actions Pending. As of the date hereof, there is no action, suit,
     claim, investigation or proceeding pending or, to the knowledge of the
     Company, threatened against the Company or any subsidiary which questions
     the validity of this Agreement or the transactions contemplated hereby or
     any action taken or to be taken pursuant hereto or thereto. There is no
     action, suit, claim, investigation or proceeding pending or, to the
     knowledge of the Company, threatened, against or involving the Company, any
     subsidiary or any of their respective properties or assets, except as would
     not have a Material Adverse Effect. Except as would not have a Material
     Adverse Effect, there are no outstanding orders, judgments, injunctions,
     awards or decrees of any court, arbitrator or governmental or regulatory
     body against the Company or any subsidiary.

        (n) Compliance with Law. The Company and each of its subsidiaries has
     complied with and is not in violation of any applicable provision of any
     statute, law or regulation with respect to the conduct of its business
     except for failures to comply or violations that would not have a Material
     Adverse Effect and have all franchises, permits, licenses, consents and
     other governmental or regulatory authorizations and approvals necessary for
     the conduct of their respective businesses as now being conducted by them
     except for franchises, permits, licenses, consents and other governmental
     or regulatory authorizations and approvals, the failure to possess which,
     individually or in the aggregate, could not reasonably be expected to have
     a Material Adverse Effect.

        (o) Taxes. The Company and each subsidiary has filed all material Tax
     Returns which it is required to file under applicable laws and the Company
     or a subsidiary has paid all material Taxes due and owing by it or any
     subsidiary (whether or not such material Taxes are required to be shown on
     a Tax Return) and has withheld and paid over to the appropriate taxing
     authorities all material Taxes which it is required to withhold from
     amounts paid or owing to any employee, stockholder, creditor or other third
     parties; and since December 31, 2001, the charges, accruals and reserves
     for material Taxes with respect to the Company (including any provisions
     for deferred income taxes) reflected on the books of the

                                       4
<PAGE>

     Company are in the aggregate adequate to cover any material Tax liabilities
     of the Company if its current tax year were treated as ending on the date
     hereof.

        No material written claim has been made by a taxing authority in a
     jurisdiction where the Company does not file tax returns that the Company
     or any subsidiary is or may be subject to taxation by that jurisdiction.
     Except as would not have a Material Adverse Effect, (i) to the best of the
     Company's knowledge there are no foreign, federal, state or local tax
     audits or administrative or judicial proceedings pending or being conducted
     with respect to the Company or any subsidiary; (ii) no information related
     to Tax matters has been requested by any foreign, federal, state or local
     taxing authority; and, (iii) except as disclosed above, no written notice
     indicating an intent to open an audit or other review has been received by
     the Company or any subsidiary from any foreign, federal, state or local
     taxing authority.

        For purposes of this Section 2.1(o):

        "Tax" or "Taxes" means federal, state, county, local, foreign, or other
        income, gross receipts, ad valorem, franchise, profits, sales or use,
        transfer, registration, excise, utility, environmental, communications,
        real or personal property, capital stock, license, payroll, wage or
        other withholding, employment, social security, severance, stamp,
        occupation, alternative or add-on minimum, estimated and other taxes of
        any kind whatsoever (including, without limitation, deficiencies,
        penalties, additions to tax, and interest attributable thereto) whether
        disputed or not.

        "Tax Return" means any return, information report or filing with respect
        to Taxes, including any schedules attached thereto and including any
        amendment thereof.

        (p) Certain Fees. No brokers, finders or financial advisory fees or
     commissions will be payable by the Company or any subsidiary with respect
     to the transactions contemplated by this Agreement.

        (q) Operation of Business. The Company and each of the subsidiaries owns
     or possesses all patents, trademarks, service marks, trade names,
     copyrights, licenses and authorizations as set forth in the SEC Documents
     or on the Disclosure Letter hereto, and all rights with respect to the
     foregoing, which are necessary for the conduct of its business as now
     conducted and, to the Company's knowledge, without any conflict with the
     rights of others.

        (r) Insurance. The Company maintains insurance in such amounts and
     covering such risks as is adequate in all material respects for the conduct
     of its business and the value of its properties and as is customary for
     companies engaging in similar businesses and similar industries.

        (s) Books and Records. The financial records of the Company and its
     subsidiaries accurately reflect in all material respects the information
     relating to the business of the Company and the subsidiaries, the location
     and collection of their assets, and the nature of all transactions giving
     rise to the obligations or accounts receivable of the Company or any
     subsidiary.

        (t) Material Agreements. Neither the Company nor any subsidiary is a
     party to any Material Agreement. Except as would not have a Material
     Adverse Effect, the Company and each of its subsidiaries has performed all
     the obligations required to be performed by them to date under the Material
     Agreements, have received no notice of default and, to the best of the
     Company's knowledge are not in default under any Material Agreement now in
     effect, the result of which would cause a Material Adverse Effect. No
     written or oral contract, instrument, agreement, commitment, obligation,
     plan or arrangement of the Company or of any subsidiary limits the payment
     of dividends on the Common Stock.

        (u) Transactions with Affiliates. There are no material loans, leases,
     agreements, contracts, royalty agreements, management contracts or
     arrangements or other continuing transactions exceeding $100,000 between
     (A) the Company or any subsidiary on the one hand, and (B) on the other
     hand, any officer, employee, consultant or director of the Company, or any
     of its subsidiaries, or any person owning 5% or more of the capital stock
     of the Company or any subsidiary or any member of the immediate family of
     such officer, employee, consultant, director or stockholder or any
     corporation or other entity controlled by such officer, employee,
     consultant, director or stockholder, or a member of the immediate family of
     such officer, employee, consultant, director or stockholder.

                                       5

        (v) Securities Laws. The Company has complied in all material respects
     with all applicable federal and state securities laws in connection with
     the offer, issuance and sale of the Shares hereunder. Neither the Company
     nor anyone acting on its behalf, directly or indirectly, has sold, offered
     to sell or solicited offers to buy the Shares or similar securities to, or
     solicited offers with respect thereto from, or entered into any preliminary
     conversations or negotiations relating thereto with, any person (other than
     the Purchaser), so as to bring the issuance and sale of the Shares under
     the registration provisions of the Securities Act and applicable state
     securities laws. Neither the Company nor any of its Affiliates, nor any
     person acting on its or their behalf, has engaged in any form of general
     solicitation or general advertising (within the meaning of Regulation D
     under the Securities Act) in connection with the offer or sale of the
     Shares.

        (w) Employees. Neither the Company nor any subsidiary has any collective
     bargaining arrangements or agreements covering any of its employees.
     Neither the Company nor any subsidiary is in breach of any employment
     contract, agreement regarding proprietary information, noncompetition
     agreement, nonsolicitation agreement, confidentiality agreement, or any
     other similar contract or restrictive covenant to which the Company is a
     party, relating to the right of any officer, employee or consultant to be
     employed or engaged by the Company or such subsidiary, except for any such
     breach which would not reasonably be expected to have a Material Adverse
     Effect. Since June 30, 2001, no officer, consultant or key employee of the
     Company or any subsidiary whose termination, either individually or in the
     aggregate, would reasonably be expected to have a Material Adverse Effect,
     has terminated or, to the knowledge of the Company, has any present
     intention of terminating his or her employment or engagement with the
     Company or any subsidiary.

        (x) Absence of Certain Developments. Except as would not have a Material
     Adverse Effect, since March 31, 2002, neither the Company nor any
     subsidiary has:

           (i) issued any stock, bonds or other corporate securities or any
        rights, options or warrants with respect thereto (other than pursuant to
        equity incentive plans or arrangements adopted by the Company) or upon
        conversion of convertible securities issued prior to March 31, 2002;

           (ii) borrowed any material amount or incurred or become subject to
        any material liabilities (absolute or contingent) except liabilities

        liabilities paid in the ordinary course of business;

           (iv) declared or made any payment or distribution of cash or other
        property to stockholders with respect to its stock, or purchased or

        consistent with prior quarters) or waived any rights of material value,
        whether or not in the ordinary course of business, or suffered the loss
        of any material amount of prospective business;

           (vi) made any material changes in employee compensation except in the

           (x) experienced any material problems with labor or management in
        connection with the terms and conditions of their employment; or

                                       6

        the aggregate would be material to the Company and its subsidiaries,
        taken as a whole.

        (aa) Acknowledgment Regarding the Purchaser's Purchase of Shares.
     Company acknowledges and agrees that the Purchaser is acting solely in the
     capacity of arm's length purchaser with respect to this Agreement and the
     transactions contemplated hereunder. The Company further acknowledges that
     the Purchaser is not acting as a financial advisor or fiduciary of the
     Company (or in any similar capacity) with respect to this Agreement and the
     transactions contemplated hereunder.

     SECTION 2.2.  Representations and Warranties of the Purchaser.  The
Purchaser hereby makes the following representations and warranties to the
Company:

        (a) Organization and Standing of the Purchaser. The Purchaser is a
     corporation duly incorporated, validly existing and in good standing under
     the laws of the Cayman Islands.

        (b) Authorization and Power. The Purchaser has the requisite power and
     authority and financial resources to enter into and perform the Transaction
     Documents and to purchase the Shares being sold to it hereunder. The
     execution, delivery and performance of the Transaction Documents by the
     Purchaser and the consummation by it of the transactions contemplated
     hereby and thereby have been duly authorized by all necessary corporate
     action. The Transaction Documents have been duly executed and delivered by
     the Purchaser, and constitute valid and binding obligations of the
     Purchaser enforceable against the Purchaser in accordance with their terms,
     except as such enforceability may be limited by applicable bankruptcy,
     insolvency, reorganization, moratorium, liquidation, conservatorship,
     receivership or similar laws relating to, or affecting generally the
     enforcement of, creditors' rights and remedies or by other equitable
     principles of general application.

        (c) No Conflicts. The execution, delivery and performance of this
     Agreement by the Purchaser and the consummation by the Purchaser of the
     transactions contemplated herein do not and will not (i) violate any
     provision of the Purchaser's charter or bylaws, (ii) conflict with, or
     constitute a default (or an event which with notice or lapse of time or
     both would become a default) under, or give to others any rights of
     termination, amendment, acceleration or cancellation of, any agreement,
     mortgage, deed of trust, indenture, note, bond, license, lease agreement,
     instrument or obligation to which the Purchaser is a party, (iii) create or
     impose a lien, charge or encumbrance on any property of the Purchaser under
     any agreement or any commitment to which the Purchaser is a party or by
     which the Purchaser is bound or by which any of its respective properties
     or assets are bound, or (iv) result in a violation of any federal, state or
     local statute, rule, regulation, order, judgment or decree (including any
     federal or state securities laws and regulations) applicable to the
     Purchaser or any of its subsidiaries or by which any property or asset of
     the Purchaser or any of its subsidiaries are bound, except, in all cases,
     for such conflicts, defaults, termination, amendments, accelerations,
     cancellations and violations as would not, individually or in the
     aggregate, have a Purchaser Material Adverse Effect on the Purchaser. No
     consent, authorization or order of, or make any filing or registration
     with, any court or governmental agency is required by the Purchaser in
     order for it to execute, deliver or perform any of its obligations under
     this Agreement, or purchase the Shares in accordance with the terms hereof.

        (d) Financial Risks. The Purchaser acknowledges that it is able to bear
     the financial risks associated with an investment in the Shares and the
     Warrants and that it has been given full access to such records of the
     Company and the subsidiaries and to the officers of the Company and the
     subsidiaries as it has deemed necessary or appropriate to conduct its due
     diligence investigation. The Purchaser is capable of evaluating the risks
     and merits of an investment in the Shares and the Warrants by virtue of its
     experience as an investor and its knowledge, experience, and sophistication
     in financial and business matters and the Purchaser is capable of bearing
     the entire loss of its investment in the Shares and the Warrants.

        (e) Accredited Investor. The Purchaser is an "accredited investor" as
     defined in Regulation D promulgated under the Securities Act.

                                       7
<PAGE>

        (f) General. The Purchaser understands that the Company is relying upon
     the truth and accuracy of the representations, warranties, agreements,
     acknowledgments and understandings of the Purchaser set forth herein in
     order to determine the suitability of the Purchaser to acquire the Shares.

        (g) Litigation; Claims. There are no lawsuits or proceedings pending or,
     to the knowledge of the Purchaser, threatened, against the Purchaser or any
     subsidiary, nor has the Purchaser received any written or oral notice of
     any action, suit, proceeding or investigation. No judgment, order, writ,
     injunction or decree or award has been issued by or, to the knowledge of
     the Purchaser, requested of any court, arbitrator or governmental agency.

        (h) Investment Intent. The Purchaser is acquiring the Shares and the
     Warrants 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 the Purchaser's right, subject
     to the provisions of this Agreement, at all times to sell or otherwise
     dispose of all or any part of the Shares and the Warrants pursuant to an
     effective registration statement under the Securities Act or under an
     exemption from such registration and in compliance with applicable federal
     and state securities laws. Nothing contained herein shall be deemed a
     representation or warranty by such Purchaser to hold the Shares or Warrants
     for any period of time.

                                   ARTICLE 3

                                   COVENANTS

     The Company covenants with the Purchaser as follows:

     SECTION 3.1.  The Shares.  As of the date of each applicable Draw Down
Notice, the Company will have authorized and reserved, free of preemptive rights
and other similar contractual rights of stockholders, a sufficient number of its
authorized but unissued shares of its Common Stock to cover the Draw Down Shares
to be issued in connection with such Draw Down requested under this Agreement.
The Draw Down Shares to be issued under this Agreement, when paid for and issued
in accordance with the terms hereof, shall be duly and validly issued and
outstanding, fully paid and non-assessable, and the Purchaser shall be entitled
to all rights accorded to a holder of Common Stock. Anything in this Agreement
to the contrary notwithstanding, (i) at no time will the Company request a Draw
Down which would result in the issuance of an aggregate number of shares of
Common Stock pursuant to this Agreement which exceeds 19.9% of the number of
shares of Common Stock issued and outstanding on the date hereof without first
obtaining stockholder approval of such excess issuance, or such other amount as
would require stockholder approval under rules of the Principal Market or
otherwise without first obtaining stockholder approval of such excess issuance,
and (ii) the Company may not make a Draw Down to the extent that, after such
purchase by the Purchaser, the sum of the number of shares of Common Stock
beneficially owned by the Purchaser and its affiliates would result in
beneficial ownership by the Purchaser and its affiliates of more than 9.999% of
the then outstanding shares of Common Stock. For purposes of the immediately
preceding sentence, beneficial ownership shall be determined in accordance with
Section 13(d) of the Exchange Act.

     SECTION 3.2.  Securities Compliance.  If applicable, the Company shall
notify the Principal Market, in accordance with its rules and regulations, of
the transactions contemplated by this Agreement, and shall take all other
necessary action and proceedings as may be required and permitted by applicable
law, rule and regulation, for the legal and valid issuance of the Shares and the
Warrants to the Purchaser.

     SECTION 3.3.  Registration and Listing.  The Company will use its
commercially reasonable best efforts to cause its Common Stock to continue to be
registered under Section 12(g) of the Exchange Act, will comply in all respects
with its reporting and filing obligations under the Exchange Act, will comply
with all requirements related to any registration statement filed pursuant to
this Agreement, and will not voluntarily take any action or file any document
(whether or not permitted by the Securities Act or the Exchange Act or the rules
promulgated thereunder) to terminate or suspend such registration or to
terminate or suspend its reporting and filing obligations under the Exchange Act
or Securities Act, except as permitted herein. The Company will use its
commercially reasonable best efforts to continue the listing or trading of its
Common
                                       8
<PAGE>

Stock on the Principal Market and will comply in all respects with the Company's
reporting, filing and other obligations under the bylaws or rules of the
Principal Market and shall provide the Purchaser's counsel with copies of any
correspondence to or from such Principal Market which questions or threatens
delisting of the Common Stock, within three (3) Trading Days of the Company's
receipt thereof.

     SECTION 3.4.  Escrow Arrangement.  The Company and the Purchaser shall
enter into an escrow arrangement with Feldman Weinstein, LLP (the "Escrow
Agent") in the form of Exhibit B hereto respecting payment against delivery of
the Draw Down Shares.

     SECTION 3.5.  Registration Rights Agreement.  The Company and the Purchaser
shall enter into the Registration Rights Agreement in the Form of Exhibit A
hereto. Before the Purchaser shall be obligated to accept a Draw Down request
from the Company, the Company shall have caused a sufficient number of shares of
Common Stock to be registered to cover the Draw Down Shares to be issued in
connection with such Draw Down.

     SECTION 3.6.  Accuracy of Registration Statement.  On each Settlement Date,
the Registration Statement and the prospectus therein shall not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein not
misleading in light of the circumstances under which they were made; and on such
Settlement Date the Registration Statement and the prospectus therein will not
include any untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided, however, the
Company makes no representations or warranties as to the information contained
in or omitted from the Registration Statement and the prospectus therein in
reliance upon and in conformity with the information furnished in writing to the
Company by the Purchaser specifically for inclusion in the Registration
Statement and the prospectus therein.

     SECTION 3.7.  Compliance with Laws.  The Company shall comply, and cause
each subsidiary to comply, with all applicable laws, rules, regulations and
orders, noncompliance with which would reasonably be expected to have a Material
Adverse Effect.

     SECTION 3.8.  Keeping of Records and Books of Account.  The Company shall
keep and cause each subsidiary to keep adequate records and books of account, in
which entries that are complete in all material respects will be made in
accordance with GAAP consistently applied, reflecting all financial transactions
of the Company and its subsidiaries, and in which, for each fiscal year, all
proper reserves for depreciation, depletion, obsolescence, amortization, taxes,
bad debts and other purposes in connection with its business shall be made.

     SECTION 3.9.  Notice of Certain Events Affecting Registration; Suspension
of Right to Request a Draw Down.  THE COMPANY WILL PROMPTLY NOTIFY THE PURCHASER
IN WRITING UPON THE OCCURRENCE OF ANY OF THE FOLLOWING EVENTS IN RESPECT OF THE
REGISTRATION STATEMENT OR RELATED PROSPECTUS IN RESPECT OF THE SHARES: (i)
receipt of any request for additional information from the SEC or any other
federal or state governmental authority during the period of effectiveness of
the Registration Statement the response to which would require any amendments or
supplements to the Registration Statement or related prospectus; (ii) the
issuance by the SEC or any other federal or state governmental authority of any
stop order suspending the effectiveness of the Registration Statement or the
initiation of any proceedings for that purpose; (iii) receipt of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Shares for sale in any jurisdiction in which
the Purchaser is entitled to sell the Shares hereunder or the receipt of notice
with respect to the initiation of any proceeding for such purpose; (iv) becoming
aware that any statement made in the Registration Statement or related
prospectus or any document incorporated or deemed to be incorporated therein by
reference is untrue in any material respect or requires the making of any
changes in the Registration Statement, related prospectus or documents so that,
in the case of the Registration Statement, it will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading, and
that in the case of the related prospectus, it will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in the light of

                                       9
<PAGE>

the circumstances under which they were made, not misleading; and (v) the
Company's determination that the filing of a post-effective amendment or
withdrawal to the Registration Statement is required. The Company shall not
deliver to the Purchaser any Draw Down Notice during the continuation of any of
the foregoing events. The Company shall promptly make available to the Purchaser
any such supplements or amendments to the related prospectus, at which time,
provided that the registration statement and any supplements and amendments
thereto are then effective, the Company may recommence the delivery of Draw Down
Notices.

     SECTION 3.10.  Consolidation; Merger.  The Company shall not, at any time
prior to the termination of this Agreement, effect any merger or consolidation
of the Company with or into, or a transfer of all or substantially all of the
assets of the Company to, another entity (a "Consolidation Event") unless the
resulting successor or acquiring entity (if not the Company) assumes by written
instrument or by operation of law the obligation to deliver to the Purchaser
such shares of Common Stock and/or securities as the Purchaser is entitled to
receive pursuant to this Agreement.

     SECTION 3.11.  Minimum Commitment Amount.  During the Commitment Period,
the Company shall make Draw Downs of at least $250,000, in the aggregate,
pursuant to this Agreement. In the event that the Company fails to make Draw
Downs of at least $250,000, in the aggregate, during the Commitment Period, the
Company shall pay the Purchaser, as liquidated damages, within five (5) days
from the end of the Commitment Period, an amount equal to $250,000 minus the
aggregate Purchase Price of all Draw Downs.

     SECTION 3.12.  Non-Public Information.  The Company covenants and agrees
that neither it nor any other Person acting on its behalf will provide the
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.

     The Purchaser covenants with the Company as follows:

     SECTION 3.13.  No Short Provision.  The Purchaser shall not engage in short
sales of the Common Stock (as defined in applicable SEC rules and the Principal
Market rules) during the term of this Agreement.

the Purchaser shall deliver to the Company a certified copy of the resolution of
the board of directors of the Purchaser authorizing the Purchaser's signatory to

     suspended by the SEC or the Principal Market (except for any suspension of
     trading of limited duration agreed to by the Company, which suspension
     shall be terminated prior to the delivery of each Draw Down Notice), and,
     at any time prior to such Draw Down Notice, trading in securities generally
     as reported on the Principal Market shall not have been suspended or
     limited, or minimum prices shall not have been established on securities
     whose trades are reported on the Principal Market unless the general
     suspension or limitation shall have been terminated prior to the delivery
     of such Draw Down Notice.

        (d) Material Adverse Effect. No Material Adverse Effect and no
     Consolidation Event where the successor entity has not agreed to deliver to
     the Purchaser such shares of stock and/or securities as the Purchaser is
     entitled to receive pursuant to this Agreement, such occurrences to be
     determined in accordance with Section 8.9 herein.

        (e) Opinion of Counsel. The Purchaser shall have received a "bring-down"
     letter from the Company's counsel, confirming that the Registration
     Statement is effective.

                                   ARTICLE 5

                                DRAW DOWN TERMS

     SECTION 5.1.  Draw Down Terms.  Subject to the satisfaction of the
conditions set forth in this Agreement, the parties agree as follows:

        (a) The Company may, in its sole discretion, issue and exercise draw
     downs against the Commitment Amount (each a "Draw Down") during the
     Commitment Period, which Draw Downs the Purchaser shall be obligated to
     accept, subject to the terms and conditions herein.

        (b) Only one Draw Down shall be allowed in each Draw Down Pricing Period
     and the Company may not exercise a Draw Down until the applicable Trading
     Cushion has elapsed since the end of the previous Draw Down Pricing Period.
     The number of shares of Common Stock purchased by the Purchaser with
     respect to each Draw Down shall be determined as set forth in Section
     5.1(e) herein and settled on or before the 3rd Trading Day immediately
     after the Draw Down Pricing Period (each such settlement period and each
     such settlement date referred to as a "Settlement Period" and a "Settlement
     Date", respectively).

        (c) In connection with each Draw Down Pricing Period, the Company may
     set the Threshold Price in the Draw Down Notice.

        (d) The minimum Investment Amount for any Draw Down shall be $50,000 and
     the maximum Investment Amount as to each Draw Down shall be equal to 10% of
     the average of the VWAPs for the 60 Trading Days immediately prior to the
     applicable Commencement Date (defined below) multiplied by the total
     aggregate trading volume in respect of the Common Stock for such period.
     Notwithstanding anything herein to the contrary, in the event the minimum
     Investment Amount is greater than the maximum Investment Amount, as to such
     Draw Down only, the minimum Investment Amount shall equal the maximum
     Investment Amount, but in no event shall the minimum Investment Amount be
     less than $25,000, such that if the maximum Investment Amount is less than
     $25,000, then the Company shall be precluded from exercising a Draw Down at
     such time.

                                       12
<PAGE>

        (e) The number of Shares of Common Stock to be issued on each Settlement
     Date shall be a number of shares equal to the sum of the quotients (for
     each Trading Day within the Draw Down Pricing Period) of (x) 1/20th of the
     Investment Amount, and (y) the Purchase Price on each Trading Day within
     the Draw Down Pricing Period, subject to the following adjustments:

           (i) if the VWAP on a given Trading Day is less than the Threshold
        Price, then that portion of the Investment Amount to be paid on the
        immediately pending Settlement Date shall be reduced by 1/20th of the
        Investment Amount and such Trading Day shall be withdrawn from the Draw
        Down Pricing Period; and

           (ii) if during any Trading Day during the Draw Down Pricing Period
        trading of the Common Stock on the Principal Market is suspended for
        more than 3 hours, in the aggregate, or if any Trading Day during the
        Draw Down Pricing Period is shortened because of a public holiday, then
        that portion of the Investment Amount to be paid on the immediately
        pending Settlement Date shall be reduced by 1/20th of the Investment
        Amount for each such suspension and such Trading Days shall be withdrawn
        from the Draw Down Pricing Period; and

           (iii) if during any Trading Day during the Draw Down Pricing Period
        sales of Draw Down Shares pursuant to the Registration Statement are
        suspended by the Company in accordance with Sections 3(d) or 5(e) of the
        Registration Rights Agreement for more than three (3) hours, in the
        aggregate, during the Draw Down Pricing Period, then that portion of the
        Investment Amount to be paid on the immediately pending Settlement Date
        shall be reduced by 1/20th of the Investment Amount and such Trading
        Days shall be withdrawn from the Draw Down Pricing Period.

        (f) The Company must inform the Purchaser by delivering a draw down
     notice, in the form of Exhibit D hereto (the "Draw Down Notice"), via
     facsimile transmission in accordance with Section 8.4 as to the amount of
     the Draw Down (the "Investment Amount") the Company wishes to exercise. The
     Draw Down Notice shall also inform the Purchaser the first day of the Draw
     Down Pricing Period (the "Commencement Date"); provided; however, if the
     Commencement Date shall be the date on which the Draw Down Notice is
     delivered, the Draw Down Notice must delivered to the Purchaser at least 1
     hour before trading commences on such Trading Day date. At no time shall
     the Purchaser be required to purchase more than the maximum Investment
     Amount for a given Draw Down Pricing Period.

        (g) On or before each Settlement Date, the Shares purchased by the
     Purchaser shall be delivered to The Depository Trust Company ("DTC") on the
     Purchaser's behalf. Upon the Company electronically delivering whole shares
     of Common Stock to the Purchaser or its designees via DTC through its
     Deposit Withdrawal Agent Commission ("DWAC") system prior to 1:00 p.m. ET,
     the Purchaser shall wire transfer immediately available funds to the
     Company's designated account on such day. Upon the Company electronically
     delivering whole shares of Common Stock to the Purchaser or its designee's
     DTC account via DWAC after 1:00 p.m. ET, the Purchaser shall wire transfer
     next day available funds to the Company's designated account on such day.
     In the event that either party elects to use the Escrow Agent, the Shares
     shall be credited by the Company to the DTC account designated by the
     Purchaser via DWAC upon receipt by the Escrow Agent of payment for the Draw
     Down Shares into the Escrow Agent's master escrow account and notice to the
     Company thereof, all as further set forth in the Escrow Agreement. The
     Escrow Agent shall be directed to pay the purchase price to the Company.

        (h) The Company understands that a delay in the delivery of the Draw
     Down Shares into the Purchaser's DTC account beyond 5 Trading Days after
     the dates set forth herein or in the Escrow Agreement, as may be
     applicable, could result in economic loss to the Purchaser. Notwithstanding
     anything herein to the contrary, as compensation to the Purchaser for such
     loss, the Company agrees to pay late payments to the Purchaser for late
     delivery after 5 Trading Days from such dates in accordance with the
     following schedule (where "No. Trading Days Late" is defined as the number
     of Trading Days beyond 5 Trading Days from the dates set forth herein or in
     the Escrow Agreement, as applicable, on

     The Company shall pay any payments incurred under this Section 5.1(h) in
immediately available funds upon demand. Nothing herein shall limit the
Purchaser's right to pursue injunctive relief and/or actual damages for the
Company's failure to issue and deliver the Draw Down Shares to the Company.

in Section 6.2.

     SECTION 6.2.  Other Termination.

        (a) This Agreement shall terminate upon one (1) Trading Day's notice if
     (i) an event resulting in a Material Adverse Effect has occurred and has
     not been cured for a period of ninety (90) days after giving notice
     thereof, (ii) the Common Stock is de-listed from the Principal Market
     unless such de-listing is in connection with the Company's subsequent
     listing of the Common Stock on the Nasdaq National Market, Nasdaq SmallCap
     Market, the American Stock Exchange or the New York Stock Exchange, or
     (iii) the Company files for protection from creditors under any applicable
     law.

        (b) The Company may terminate this Agreement upon 1 Trading Day's notice
     if the Purchaser shall fail to fund a properly noticed Draw Down within 5
     Trading Days of the end of the applicable Settlement Period.

     SECTION 6.3.  Effect of Termination.  In the event of termination of this
Agreement pursuant to Section 6.2 herein, written notice thereof shall forthwith
be given to the other party and the transactions contemplated by this Agreement
shall be terminated without further action by either party. If this Agreement is
terminated as provided in Section 6.1 or 6.2 herein, this Agreement shall become
void and of no further force and effect, except for Sections 8.1, 8.2 and 8.9,
and Article 7 herein, which shall survive the termination of this Agreement.
Nothing in this Section 6.3 shall be deemed to release the Company or the
Purchaser from any liability for any breach under this Agreement, or to impair
the rights of the Company or the Purchaser to compel specific performance by the
other party of its obligations under this Agreement.

                                INDEMNIFICATION

       Section 7.1.  General Indemnity.

        (a) The Company agrees to indemnify and hold harmless the Purchaser (and
     its directors, officers, affiliates, agents, successors and assigns) from
     and against any and all losses, liabilities, deficiencies, costs, damages
     and expenses (including, without limitation, reasonable attorneys' fees,
     charges and disbursements) ("Damages") incurred by the Purchaser as a
     result of any breach of the representations, warranties or covenants made
     by the Company herein.

        (b) The Purchaser agrees to indemnify and hold harmless the Company and
     its directors, officers, affiliates, agents, successors and assigns from
     and against any and all Damages) incurred by the Company as result of any
     breach of the representations, warranties or covenants made by the
     Purchaser herein. Notwithstanding anything to the contrary herein, the
     Purchaser shall be liable under this Section 7.1(b) for only that amount as
     does not exceed the gross proceeds to the Purchaser as a result of the sale
     of the Shares.

        (c) An indemnifying party shall not be liable under this Article 7 to
     the extent that it is finally judicially determined that such Damages
     resulted or arose from the breach by the Indemnified Party of any
     representation or warranty of the Indemnified Party contained in this
     Agreement or the willful misconduct or gross negligence of the Indemnified
     Party.

     SECTION 7.2.  Indemnification Procedure.  Any party entitled to
indemnification under this Article 7 (an "Indemnified Party") will give prompt
written notice to the indemnifying party of any matters giving rise to a claim
for indemnification, describing the claim in reasonable detail; provided, that
the failure of any party entitled to indemnification hereunder to give notice as
provided herein shall not relieve the indemnifying party of its obligations
under this Article 7 except to the extent that the indemnifying party is
actually prejudiced by such failure to give notice. In case any action,
proceeding or claim is brought against an Indemnified Party in respect of which
indemnification is sought hereunder, the indemnifying party shall be entitled to
assume the defense thereof with counsel reasonably satisfactory to the
Indemnified Party. In the event that the indemnifying party advises an
Indemnified Party that it will contest such a claim for indemnification
hereunder, or fails, within thirty (30) days of receipt of any indemnification
notice to notify, in writing, the Indemnified Party of its election to defend,
settle or compromise, at its sole cost and expense, any action, proceeding or
claim (or discontinues its defense at any time after it commences such defense),
then the Indemnified Party may, at its option, defend, settle or otherwise
compromise or pay such action or claim. In any event, unless and until the
indemnifying party elects in writing to assume and does so assume the defense of
any such claim, proceeding or action, the Indemnified Party's costs (including
reasonable attorneys' fees, charges and disbursements) and expenses arising out
of the defense, settlement or compromise of any such action, claim or proceeding
shall be losses subject to indemnification hereunder. The Indemnified Party
shall cooperate fully with the indemnifying party in connection with any
settlement negotiations or defense of any such action or claim by the
indemnifying party and shall furnish to the indemnifying party all information
reasonably available to the Indemnified Party, which relates to such action or
claim. The indemnifying party shall keep the Indemnified Party apprised as to
the status of the defense or any settlement negotiations with respect thereto.
If the indemnifying party elects to defend any such action or claim, then the
Indemnified Party shall be entitled to participate in such defense with counsel
of its choice at its sole cost and expense. The indemnifying party shall not be
liable for any settlement of any action, claim or proceeding effected without
its prior written consent. Notwithstanding anything in this Article 7 to the
contrary, the indemnifying party shall not, without the Indemnified Party's
prior written consent, settle or compromise any claim or consent to entry of any
judgment in respect thereof which imposes any future obligation on the
Indemnified Party or which does not include, as an unconditional term thereof,
the giving by the claimant or the plaintiff to the Indemnified Party of a
release from all liability in respect of such claim. The indemnification
required by this Article 7 shall be made by periodic payments of the amount
thereof during the course of investigation or defense, as and when bills are
received or expense, loss, damage or liability is incurred, within ten (10)
Trading Days of written notice thereof to the indemnifying party so long

                                       15
<PAGE>

as the Indemnified Party irrevocably agrees to refund such moneys, with
interest, if it is ultimately determined by a court of competent jurisdiction
that such party was not entitled to indemnification. The indemnity agreements
contained herein shall be in addition to (a) any cause of action or similar
rights of the Indemnified Party against the indemnifying party or others, and
(b) any liabilities to which the indemnifying party may be subject.

                                   ARTICLE 8

                                 MISCELLANEOUS

acknowledge and agree that irreparable damage would occur in the event that any

specific terms or were otherwise breached. It is accordingly agreed that the
parties shall be entitled to an injunction or injunctions to prevent or cure
breaches of the provisions of this Agreement and to enforce specifically the
terms and provisions hereof or thereof, this being in addition to any other
remedy to which any of them may be entitled by law or equity.

     SECTION 8.4.  Entire Agreement; Amendment.  The Transaction Documents
contain the entire understanding of the parties with respect to the matters
covered in the Transaction Documents. No provision of this Agreement may be
waived or amended other than by a written instrument signed by the party against
whom enforcement of any such amendment or waiver is sought and no condition to
closing any Draw Down in favor of the Purchaser may be waived by the Purchaser.

     SECTION 8.5.  Notices.  Any notice, demand, request, waiver or other
