   Item 5.    EXCHANGE OF CONVERTIBLE NOTES FOR PREFERRED SHARES

     On August 13, 2001, Ultradata Systems, Incorporated ("Ultradata")
completed an exchange of 11.25% Senior Subordinated Secured Convertible
Promissory Notes (the "Notes") for 1408 of the 1424 shares of Series A
Convertible Preferred Stock now outstanding.  The Series A Preferred Stock
which was exchanged had been issued on May 16, 2000 for a purchase price of
$1,408,000, and was subject to an accrual of principal totaling 11.25% per
annum.

     The terms of the Notes include:

     1. The principal amount of the Notes is $1,748,120.

     2. The Notes will bear interest at 11.25% per annum.  In addition,
        there will be a one-time 10% interest accrual on any unpaid amount
        of the Notes on June 1, 2002.  That accrual, if unpaid, will be
        added to the principal amount of the Notes on that date.

     3. Ultradata will pay $140,000 toward the Notes in September, 2001,
        $70,000 in October, 2001, and $90,000 monthly thereafter.  Payments
        will be applied first to accrued interest, then to principal.

     4. Ultradata's obligations under the Notes are secured by a lien on
        Ultradata's assets.  The lien is subordinate to "Senior Debt," which
        is defined as any borrowing from a commercial lender in which the
        amount of the borrowing is determined by reference to accounts
        receivable and inventory.

     5. The principal and accrued interest on the Notes may be converted
        into common stock at any time at the option of the holders.  The
        conversion rate will be the lower of $3.50 or 75% of the 5-day
        average closing bid price, subject to certain anti-dilution rights.
        The total number of shares into which the Notes may be converted
        during any 90 day period cannot exceed 20% of the cumulative trading
        volume for the 66 trading days preceding the date of conversion.

     6. Ultradata may prepay any amount of the principal and interest on the
        Notes, subject to a 10% prepayment penalty.

     In connection with the sale of the Series A Preferred Stock in May 2000,
Ultradata had issued to the investors warrants to purchase up to 478,506
shares of common stock for a price of $5.00 per share until May 15, 2003.  In
connection with the exchange on August 13, 2001, Ultradata reduced the
exercise price of the warrants to $1.50 per share.

	RECITALS

Pursuant to a Convertible Preferred Stock and Warrants Purchase Agreement,
dated as of May 10, 2000, the Company sold and issued to the Investors, and
the Investors purchased, a total of 1,600 shares of the Company's Series A
Convertible Preferred Stock, $.01 par value per share (the "Series A Stock"),
together with Warrants to purchase a total of 478,506 shares of the Company's
Common Stock, $.01 par value per share (the "Common Stock"), at an exercise
price of $5.00 per share (the "Series A Warrants").  The Company has purchased
164 shares of Series A Stock from the Investors and has issued 56,118 shares
of Common Stock in exchange for 28 shares of Series A Stock.  Accordingly,
the Investors own 1,408 shares of Series A Stock as of the date of this
Agreement.

In connection with the Company's sale of the Series A Stock to the Investors,
the Company and the Investors entered into a Registration Rights Agreement,
dated as of May 16, 2000, pursuant to which the Company agreed to file a
Registration Statement with the Securities and Exchange Commission with
respect to the Investors' public sale of the Common Stock issuable upon
conversion of the Series A Stock and exercise of the Series A Warrants.  The
Company is in default under such Registration Rights Agreement.  In connection
with such default, the Company has agreed to exchange its 11.25% Senior
Subordinated Secured Convertible Notes (the "Convertible Notes") for all
shares of Series A Stock held by the Investors and to exchange Warrants to
purchase 478,506 shares of Common Stock at an exercise price of $1.50 per
share ("Substitute Warrants") for the Series A Warrants held by the Investors,
all in accordance with the terms of this Agreement.  The Company is relying
on the exemption from registration under Section 3(a)(9) of the Securities Act
of 1933, as amended, to issue the Convertible Notes and Substitute Warrants to
the Investors hereunder.


NOW, THEREFORE, the parties hereto agree as follows:

           authorizing an amendment to the Company's Certificate of
           Incorporation to increase the number of shares of Common Stock the
           Company is authorized to issue as provided in Section 6.15.

       (N) Form UCC-1 Financing Statements shall have been filed with respect

Section 2.2.    Liquidated Damages.  The parties hereto acknowledge and
agree that the amounts payable by the Company to the Investors pursuant to
the Registration Rights Agreement with respect to a Registration Default
thereunder shall constitute liquidated damages and not penalties. The parties
further acknowledge that (i) the amount of loss or damages likely to be
incurred as a result of such Registration Default is incapable or is
difficult to precisely estimate, (ii) the amounts payable as a result of a
Registration Default bear a reasonable proportion to and are not plainly or

Agreement and (iii) the parties are sophisticated business parties and have
been represented by sophisticated and able legal and financial counsel and

ARTICLE IV

Representations and Warranties of the Company

The Company represents and warrants to the Investors that, except as set
forth on the Disclosure Schedule prepared by the Company and attached hereto:

  Section 4.1.  Organization of the Company.  The Company is a corporation
duly incorporated, validly existing and in good standing under the laws of
the State of Delaware and has all requisite corporate authority to own its
properties and to carry on its business as now being conducted.  The Company's
Subsidiaries are corporations duly organized and validly existing in good
standing under the laws of the jurisdiction in which they are incorporated
and have the requisite corporate power and authority to own their properties
and to carry on their business as now being conducted.  The Company does not
have any Subsidiaries and does not own more that fifty percent (50%) of or
control any other business entity except as set forth in the SEC Documents.
The Company and each of its Subsidiaries is duly qualified and is in good
standing as a foreign corporation to do business in every jurisdiction in
which the nature of the business conducted or property owned by it makes such
qualification necessary, other than those in which the failure so to qualify
would not have a Material Adverse Effect.

  Section 4.2.  Authority.  (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 Securities pursuant to their respective
terms; (ii) the execution, issuance and delivery of the Transaction Documents,
the Convertible Notes, and the Substitute Warrants by the Company and the
consummation by it of the transactions contemplated hereby 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 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,
or similar laws relating to, or affecting generally the enforcement of,
creditors' rights and remedies or by other equitable principles of general
application.  The Company has duly and validly authorized and reserved for
issuance shares of Common Stock sufficient in number for the conversion of the
Convertible Notes and for the exercise of the Substitute Warrants.  The
Company understands and acknowledges the potentially dilutive effect to the
Common Stock of the issuance of the Conversion Shares and, upon any exercise
of the Substitute Warrants, the Warrant Shares.  The Company further
acknowledges that its obligation to issue Conversion Shares upon conversion of
the Convertible Notes and Warrant Shares upon exercise of the Substitute
Warrants in accordance with this Agreement, the Convertible Notes and the
Substitute Warrants is absolute and unconditional regardless of the dilutive
effect that such issuance may have on the ownership interests of other
stockholders of the Company and notwithstanding the commencement of any case
under 11 U.S.C. Sec 101 et seq. (the "Bankruptcy Code").

  Section 4.3.  Capitalization.  The authorized capital stock of the Company
consists of 10,000,000 shares of Common Stock, $0.01 par value per share, of
which 3,249,533 shares were issued and outstanding as of July 25, 2001 and
5,000,000 shares of preferred stock, par value $0.01 per share, of which
3,320 shares have been designated as Series A Convertible Preferred Stock, of
which 1,424 shares were issued and outstanding as of July 25, 2001.  Except
for (i) outstanding options and warrants as set forth in the SEC Documents,
(ii) 334,025 stock options awarded under the Company's 1994 Stock Option Plan
and the Company's 1996 Stock Option Plan, (iii) the outstanding shares of
Series A Stock, (iv) the outstanding Series A Warrants, and (v) as set forth
in the Disclosure Schedule, there are no outstanding Capital Shares Equivalents
nor any agreements or understandings pursuant to which any Capital Shares
Equivalents may become outstanding.  The Company is not a party to any
agreement granting preemptive, registration or anti-dilution rights to any
person with respect to any of its equity or debt securities.  All of the
outstanding shares of Common Stock of the Company have been duly and validly
authorized and issued and are fully paid and non-assessable.

  Section 4.4.  Common Stock.  The Company has registered its Common Stock
pursuant to Section 12(b) or 12(g) of the Exchange Act and is in full
compliance with all reporting requirements of the Exchange Act, and the
Company is in compliance with all requirements for the continued listing or
quotation of its Common Stock, and such Common Stock is currently listed or
quoted on a Principal Market.  As of the date hereof, the Principal Market is
the over-the-counter market, and except as set forth in the SEC Documents, the
Company has not received any notice regarding, and to its knowledge there is
no threat of, the termination or discontinuance of the eligibility of the
Common Stock for such listing.

  Section 4.5.  SEC Documents.  The Company has delivered to the Investors
true and complete copies of the SEC Documents.  The Company has not provided
the Investors any information that, according to applicable law, rule or
regulation, should have been disclosed publicly prior to the date hereof by
the Company, but which has not been so disclosed. As of their respective dates,
the SEC Documents complied in all material respects with the requirements of
the Securities Act or the Exchange Act, as the case may be, and rules and
regulations of the SEC promulgated thereunder, and the SEC Documents did not
contain any untrue statement of a material fact or omit 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.  The financial statements of the Company included in the SEC
Documents complied in all material respects with applicable accounting
requirements and the rules and regulations of the SEC or other applicable rules
and regulations with respect thereto at the time of such inclusion. 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, to the extent they exclude footnotes or
may be condensed or summary statements) and fairly present in all material
respects the financial position of the Company as of the dates thereof and
the results of operations and cash flows for the periods then ended (subject,
in the case of unaudited interim statements, to normal year-end audit
adjustments).  Neither the Company nor any of its subsidiaries has any material
indebtedness, obligations or liabilities of any kind (whether accrued,
absolute, contingent or otherwise, and whether due or to become due) that
would have been required to be reflected in, reserved against or otherwise
described in the financial statements or in the notes thereto in accordance
with GAAP, which was not fully reflected in, reserved against or otherwise
described in the financial statements or the notes thereto included in the
SEC Documents or was not incurred in the ordinary course of business consistent
with the Company's past practices since the last date of such financial
statements.  No other information provided by or on behalf of the Company to
the Investors that is not included in the SEC Documents, including, without
limitation, information referred to in Section 3.6 of this Agreement, contains
any untrue statement of a material fact or omits to state any material fact
necessary in order to make the statements therein, in the light of the
circumstance under which they are or were made, not misleading.

  Section 4.6.  Exemption from Registration; Valid Issuances.  Subject to the
accuracy of the Investors' representations in Article III, the Company's
issuance of the Convertible Notes and  Substitute Warrants under this Agreement
does not, and the Company's issuance of the Conversion Shares on the Investor's
conversion of the Convertible Notes and the Warrant Shares on the exercise of
the Substitute Warrants will not, require registration under the Securities
Act and/or any applicable state securities law.  When issued and paid for in
accordance with the Substitute Warrants and validly converted in accordance
with the terms of the Convertible Notes, the Conversion Shares and the Warrant
Shares will be duly and validly issued, fully paid, and non-assessable.
Neither the issuance of the Securities pursuant to, nor the Company's
performance of its obligations under, the Transaction Documents will (i) result
in the creation or imposition by the Company of any liens, charges, claims or
other encumbrances upon any of the Securities or, except as contemplated herein,
any of the assets of the Company, or (ii) entitle the holders of Outstanding
Capital Shares to preemptive or other rights to subscribe for or acquire the
Capital  Shares or other securities of the Company. None of the Securities
will subject the Investors to personal liability to the Company or its
creditors by reason of an Investor's possession thereof.

  Section 4.7.  No General Solicitation or Advertising in Regard to this
Transaction.  Neither the Company nor any of its affiliates nor any person
acting on its or their behalf (i) has conducted or will conduct any general
solicitation (as that term is used in Rule 502(c) of Regulation D) or general
advertising with respect to the sale of the Convertible Notes or the Substitute
Warrants, or (ii) made any offers or sales of any security or solicited any
offers to buy any security under any circumstances that would require
registration of the Securities under the Securities Act.

  Section 4.8.  No Conflicts.  The Company's execution, delivery and
performance of the Transaction Documents, the Company's performance of its
obligations under the Convertible Notes, and the Company's consummation of the
transactions contemplated hereby and thereby do not and will not (i) result in
a violation of the Company's Certificate of Incorporation or By-Laws 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 of, any
material agreement, indenture or instrument, or any "lock-up" or similar
provision of any underwriting or similar agreement to which the Company is a
party, or (iii) result in a violation of any law, rule, regulation, order,
judgment or decree (including federal and state securities laws and regulations
and the rules and regulations of the Principal Market) applicable to the
Company or by which any property or asset of the Company is bound or affected.
The Company is not otherwise in violation of any term of or in default under
its Certificate of Incorporation, any Certificate of Designations, Preferences
and Rights of any outstanding series of preferred stock or its By-laws, or any
contract, agreement, mortgage, indebtedness, indenture, instrument, judgment,
decree or order or any statute, rule or regulation applicable to the Company,
except for possible conflicts, defaults, terminations, amendments,
accelerations, cancellations and violations that would not individually or in
the aggregate have a Material Adverse Effect.  The Company's business is not
being conducted in violation of any law, ordinance or regulation of any
governmental entity, except for possible violations that either singly or in
the aggregate would not result in a Material Adverse Effect.  Except as
specifically contemplated by this Agreement and as required by the Securities
Act, the Company is not required to obtain any consent, authorization or order
of, or make any filing or registration with, any court or governmental agency
or any regulatory or self regulatory organization, in order for it to execute,
deliver or perform any of its obligations under or contemplated by the
Transaction Documents or to perform its obligations under the Convertible Notes
and Substitute Warrants, in each case in accordance with the terms hereof or
thereof.  All consents, authorizations, orders, filings and registrations
which the Company is required to obtain pursuant to the preceding sentence
have been obtained or effected on or prior to the date hereof.

  Section 4.9.  No Material Adverse Change.  Since December 31, 2000, no
Material Adverse Effect has occurred or exists with respect to the Company,
except as disclosed in any SEC Documents filed at least five (5) days prior
to the date hereof and available on EDGAR.  The Company has not taken any
steps, and does not currently expect to take any steps, to seek protection
pursuant to the Bankruptcy Code or any law generally affecting creditors'
rights nor does the Company have any knowledge or reason to believe that its
creditors intend to initiate involuntary bankruptcy proceedings.

  Section 4.10. No Undisclosed Events, Liabilities, Developments, or
Circumstances. No event, liability, development or circumstance has occurred
or exists with respect to the Company or its Subsidiaries or their respective
businesses, properties, operations or financial condition, that would be
required to be disclosed by the Company under applicable securities laws on a
registration statement filed with the SEC relating to an issuance and sale by
the Company of its Common Stock and which has not been publicly announced.

  Section 4.11. No Integrated Offering. The Company has not, directly or
indirectly, made any offers or sales of any security or solicited any offers
to buy any security, under circumstances that would require registration of
any of the Securities under the Securities Act or cause this offering of
Securities to be integrated with prior offerings of securities by the Company
for purposes of the Securities Act or any applicable stockholder approval
provisions, including, without limitation, under the rules and regulations of
the Principal Market; nor will the Company or any of its Subsidiaries take any
action or steps that would require registration of the Securities under the
Securities Act or cause the offering of the Securities to be integrated with
other offerings.

  Section 4.12. Litigation and Other Proceedings.  Except as disclosed in the
SEC Documents, there are no lawsuits or proceedings pending or, to the
knowledge of the Company, threatened, against the Company or any Subsidiary or
any of their officers or directors in their capacities as such, nor has the
Company received any written or oral notice of any such action, suit,
proceeding or investigation, which could reasonably be expected to have a
Material Adverse Effect.  Except as set forth in the SEC Documents, no
judgment, order, writ, injunction or decree or award has been issued by or,
to the knowledge of the Company, requested of any court, arbitrator or
governmental agency which could result in a Material Adverse Effect.

  Section 4.13. No Misleading or Untrue Communication.  Neither Company nor,
to the knowledge of the Company, any person representing the Company, or any
other person selling or offering to sell the Convertible Notes or the
Substitute Warrants in connection with the transaction contemplated by this
Agreement, has made, at any time, any oral communication in connection with
the offer or sale of the same which contained any untrue statement of a
material fact or omitted to state any material fact necessary in order to make
the statements, in the light of the circumstances under which they were made,
not misleading.

  Section 4.14. Material Non-Public Information.  The Company has not disclosed
to the Investors any material non-public information that (i) if disclosed,
would reasonably be expected to have a material effect on the price of the
Common Stock or (ii) according to applicable law, rule or regulation, should
have been disclosed publicly by the Company prior to the date hereof, but which
has not been so disclosed.

  Section 4.15. Insurance.  The Company and each subsidiary maintains property
and casualty, general liability, workers' compensation, environmental hazard,
personal injury and other similar types of insurance with financially sound and
reputable insurers that is adequate, consistent with industry standards and the
Company's historical claims experience. Neither the Company nor any Subsidiary
has been refused any insurance coverage sought or applied for, and neither the
Company nor any such Subsidiary has any reason to believe that it will not be
able to renew its existing insurance coverage as and when such coverage expires
or to obtain similar coverage from similar insurers as may be necessary to
continue its business at a cost that would not materially and adversely
affect the condition, financial or otherwise, or the earnings, business or
operations of the Company and its Subsidiaries, taken as a whole.  The Company
maintains officers' and directors' liability insurance in the amount of
$1,000,000.

  Section 4.16. Tax Matters.

  (a) The Company and each Subsidiary has filed all Tax Returns which it is
required to file under applicable laws; all such Tax Returns are true and
accurate and have been prepared in compliance with all applicable laws; the
Company has paid all Taxes due and owing by it or any Subsidiary (whether or
not such Taxes are required to be shown on a Tax Return) and have withheld and
paid over to the appropriate taxing authorities all 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, 1998, the charges, accruals and
reserves for Taxes with respect to the Company (including any provisions for
deferred income taxes) reflected on the books of the Company are adequate to
cover any Tax liabilities of the Company as if its current tax year were
treated as ending on the date hereof.

  (b) No 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.  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; no
information related to Tax matters has been requested by any foreign, federal,
state or local taxing authority; and, 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.  There are no material unresolved questions or claims
concerning the Company's Tax liability.  The Company (A) has not executed or
entered into a closing agreement pursuant to Sec 7121 of the Code or any
predecessor provision thereof or any similar provision of state, local or
foreign law; or (B) has not agreed to, and is not required to make any

state, local or foreign law by reason of a change in accounting method
initiated by the Company or any of its subsidiaries, has no knowledge that
the IRS has proposed any such adjustment or change in accounting method, and
does not have any application pending with any taxing authority requesting
permission for any changes in accounting methods that relate to the business
or operations of the Company.  The Company has not been a United States real
property holding corporation within the meaning of Sec 897(c)(2) of the Code
during the applicable period specified in Sec 897(c)(1)(A)(ii) of the Code.

  (c) The Company has not made an election under Sec 341(f) of the Code.  The
Company is not liable for the Taxes of another person that is not a Subsidiary
of the Company under (A) Treas. Reg. Sec 1.1502-6 (or comparable provisions of
state, local or foreign law), (B) as a transferee or successor, (C) by
contract or indemnity or (D) otherwise.  The Company is not a party to any
tax sharing agreement.  The Company has not made any payments, nor is it
obligated to make payments or a party to an agreement that could obligate it
to make any payments that would not be deductible as a result of the
applicability of Sec 280G of the Code.

  Section 4.17. Property.  Neither the Company nor any of its Subsidiaries
owns any real property.  Each of the Company and its subsidiaries has good and
marketable title to all personal property that it owns, free and clear of all
liens, encumbrances and defects except such as do not materially affect the
value of such property and do not materially interfere with the use made and
proposed to be made of such property by the Company; and to the Company's
knowledge, any real property, mineral or water rights, and buildings that the
Company holds under lease as a tenant are held by it under valid, subsisting
and enforceable leases with such exceptions as are not material and do not

or water rights, and buildings by the Company and its Subsidiaries.

  Section 4.18. Intellectual Property.  Each of the Company and its
Subsidiaries owns or possesses adequate and enforceable rights or licenses to
use all Intellectual Property necessary for the conduct of its business as now
being conducted.  None of the Company's or any Subsidiary's Intellectual
Property necessary to conduct its business as now conducted or as proposed to
be conducted have expired or terminated, or are expected to expire or
terminate within two years from the date of this Agreement.  To the Company's
knowledge, except as disclosed in the SEC Documents neither the Company nor
any of its subsidiaries is infringing upon or in conflict with any right of
any other person with respect to any Intellectual Property.  Except as
disclosed in the SEC Documents, no adverse claims have been asserted by any
person to the ownership or use of any Intellectual Property, and the Company
has no knowledge of any basis for such claim.

  Section 4.19. Internal Controls and Procedures.  The Company maintains books
and records and internal accounting controls that provide reasonable assurance
that (i) all transactions to which the Company or any Subsidiary is a party or
by which its properties are bound are executed with management's authorization;
(ii) the recorded accounting of the Company's consolidated assets is compared
with existing assets at regular intervals; (iii) access to the Company's
consolidated assets is permitted only in accordance with management's

necessary to permit preparation of the financial statements of the Company in
accordance with GAAP.

Notes.  The Company acknowledges and agrees that each of the Investors is
acting solely in the capacity of arm's-length purchaser with respect to the
Transaction Documents and the transactions contemplated thereby.  The Company
further acknowledges that no Investor is acting as a financial advisor or
fiduciary of the Company (or in any similar capacity) with respect to the
Transaction Documents and the transactions contemplated thereby and any advice
given by any of the Investors or any of their respective representatives or
agents in connection with the Transaction Documents and the transactions
contemplated thereby is merely incidental to such Investor's purchase of the
Securities.  The Company further represents to each Investor that the Company's
decision to enter into the Transaction Documents has been based solely on the
independent evaluation by the Company and its representatives.

  Section 4.22. Labor Matters.  Neither the Company nor any of its Subsidiaries
is involved in any union labor dispute nor, to the knowledge of the Company
or any of its Subsidiaries, is any such dispute threatened.  Neither the
Company nor any of its Subsidiaries is a party to a collective bargaining
agreement, and the Company and its Subsidiaries believe that relations with
their employees are good.  No executive officer (as defined in Rule 501(f) of
the Securities Act) has notified the Company that such officer intends to
leave the Company or otherwise terminate such officer's employment with the
Company.

  Section 4.23. Environmental Laws.  The Company and its Subsidiaries (i) are
in compliance with any and all applicable Environmental Laws, (ii) have
received all permits, licenses or other approvals required of them under
applicable Environmental Laws to conduct their respective businesses and

Effect.

  Section 4.24. Regulatory Permits.  The Company and its Subsidiaries possess
all certificates, authorizations and permits issued by the appropriate federal,
state or foreign regulatory authorities necessary to conduct their respective

Company nor any such Subsidiary has received any notice of proceedings
relating to the revocation or modification of any such certificate,
authorization or permit.

  Section 4.25. No Materially Adverse Contracts, Etc.  Neither the Company nor
any of its Subsidiaries is subject to any charter, corporate or other legal
restriction, or any judgment, decree, order, rule or regulation which in the

Company nor any of its Subsidiaries is a party to any contract or agreement
that in the reasonable judgment of the Company's officers has or is expected
to have a Material Adverse Effect.

  Section 4.26. Certain Transactions.  Except as set forth in the SEC Documents

timely satisfy each of the conditions to be satisfied by it as provided in

Conversion and Warrant Shares.  If the Company does not have a sufficient
number of authorized, but unissued and unreserved, shares of Common Stock to
reserve for issuance 200% of the Issuable Conversion and Warrant Shares, then
upon approval of the amendment to the Company's Certificate of Incorporation
referred to in Section 6.15, the Company shall reserve additional shares of
Common Stock such that the total number of shares of Common Stock reserved for
issuance equals 200% of the Issuable Conversion and Warrant Shares as of the
date of such approval.

  Section 6.4.  Listing of Common Stock.  If the Company's Common Stock is at
any time hereafter listed on a Principal Market (including the OTC Bulletin
Board), the Company shall maintain such listing and, as soon as required by the
rules of the Principal Market and any other national securities exchange or
automated quotation system, if any, upon which shares of Common Stock are
listed, shall list the Conversion Shares and the Warrant Shares on the
Principal Market and each such other exchange or system. The Company further
agrees, if the Company applies to have the Common Stock traded on any other
Principal Market, it will include in such application the Conversion Shares
and the Warrant Shares, and will take such other action as is necessary or
desirable in the opinion of the Investors to cause the Conversion Shares and
Warrant Shares to be listed on such other Principal Market as promptly as
possible.  The Company will take all action necessary to continue the listing
and trading of its Common Stock on a Principal Market (including, without
limitation, maintaining sufficient net tangible assets) 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 Investors 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

Exchange Act, will use its best efforts to comply in all respects with its
reporting and filing obligations under the Exchange Act, and will not take any
action or file any document (whether or not permitted by the Exchange Act or
the rules thereunder) to terminate or suspend such registration or to
terminate or suspend its reporting and filing obligations under the Exchange
Act until the Investors have disposed of all of their Registrable Securities.

  Section 6.6.  Legends.  The certificates evidencing the Registrable
Securities shall be free of legends, except as set forth in Article IX.

  Section 6.7.  Corporate Existence; Conflicting Agreements.  The Company will

  Section 6.8.    Consolidation; Merger.  The Company shall not, at any time
after the date hereof, effect any merger or consolidation of the Company with
or into, or a transfer of all or substantially all of the assets of the

successor or acquiring entity (if not the Company) assumes by written
instrument or by operation of law the obligation to deliver to the Investors
such shares of stock and/or securities as the Investors are entitled to receive
pursuant to this Agreement, the Convertible Notes or the Substitute Warrants.

  Section 6.9.  Issuance of Convertible Notes and Warrant Shares.  The
issuance of the Convertible Notes and the Substitute Warrants at the Closing
and the issuance of the Conversion Shares on conversion of the Convertible
Notes shall be made pursuant to the exemption from registration under Section
3(a)(9) of the Securities Act, and the issuance of the Warrant Shares pursuant
to exercise of the Substitute Warrants shall be made in accordance with the
provisions and requirements of Section 4(2) and Section 4(6) of the Securities
Act or Regulation D and any applicable state securities law.  The Company shall
take such action as reasonably necessary to qualify the Convertible Notes for,
or obtain exemption for the Convertible Notes for, issuance to the Investors
at the Closing pursuant to this Agreement under applicable securities or "Blue
Sky" laws of the states of the United States, and shall provide evidence of
any such action so taken to the Investors on or prior to the Closing Date.

the Securities required under the applicable securities or "Blue Sky" laws of
the states of the United States following the Closing Date.

  Section 6.12. Relief in Bankruptcy.  The Company shall not seek judicial
relief from its obligations hereunder except pursuant to the Bankruptcy Code.

hereby waives to the fullest extent permitted any rights to relief it may have
under 11 U.S.C. Sec 362 in respect of the conversion of the Convertible Notes
and the exercise of the Substitute Warrants.  The Company agrees, without cost
or expense to the Investors, to take or consent to any and all action necessary
to effectuate relief under 11 U.S.C. Sec 362.

  Section 6.13. Cancellation of Series A Stock and Series A Warrants.  The
Company shall cancel all shares of Series A Stock and all Series A Warrants
delivered to it at the Closing and shall not sell or otherwise issue such
shares of Series A Stock or Series A Warrants to any Person after the Closing
Date.

  Section 6.14. Financial Information.  Until all Registrable Securities may
be sold without registration under the Securities Act, the Company shall send
the following to each holder of Registrable Securities:  (i) within five (5)
days after the filing thereof with the SEC, a copy of its Annual Report on
Form 10-KSB, its Quarterly Reports on Form 10-QSB, any Current Reports on Form
8-K and any registration statements or amendments (other than on Form S-8)
filed pursuant to the Securities Act; (ii) on the same day as the release
thereof, copies of all press releases issued by the Company or any of its
Subsidiaries; and (iii) copies of any notices and other information made
available or given to the stockholders of the Company generally,
contemporaneously with the making available or giving thereof to the
stockholders.  The Company may send such information to each Investor by
e-mail to the e-mail address specified in Article XII.

  Section 6.15  Proxy Statement.  If at any time after the Closing Date, the
Company has fewer than 2,000,000 shares of Common Stock reserved and authorized
for issuance upon conversion of the Convertible Notes, the Company shall,
within twenty (20) business days of the date on which such event occurs, file
with the SEC a notice of a stockholders' meeting and a proxy statement (which
proxy statement has been previously reviewed by the Investors and a counsel
of their choice), which shall be for a stockholders' meeting to be held not
later than sixty (60) days after the date of such filing with the SEC,
soliciting each such stockholder's affirmative vote at such stockholders'
meeting for approval of an amendment to the Company's Certificate of
Incorporation to increase the number of shares of Common Stock the Company is
authorized to issue.  The amendment to the Company's Certificate of
Incorporation shall increase the number of authorized shares of Common Stock
such that the Company will have authorized and reserved for issuance upon
conversion of the Convertible Notes not less than 300% of the number of shares
of Common Stock that would be issuable on conversion of the Convertible Notes
on the business day immediately preceding the date of filing such proxy
statement with the SEC.  Promptly after the earlier of (x) the expiration of
the period during which the SEC may, but does not, review such notice and
proxy statement, or (y) the SEC's approval of such notice of meeting and proxy
statement, if the SEC reviews them, the Company shall provide each stockholder
entitled to vote at a meeting of stockholders of the Company with such notice
of a stockholders' meeting and proxy statement, and the Company shall use its
best efforts to solicit its stockholders' approval of such amendment to the
Certificate of Incorporation and cause the Board of Directors of the Company
to recommend to the stockholders that they approve such proposal.  If the
Company fails to give notice or hold a stockholders' meeting within sixty (60)
days after the filing of such proxy statement with the SEC, if the SEC does
not review the proxy statement, or one hundred twenty (120) days after the
date of such filing, if the SEC reviews the proxy statement (unless such
failure is the result solely of the actions of the Investors), then, as
partial relief (which remedy shall not be exclusive of any other remedies
available at law or in equity), the Company shall pay to each holder of
Convertible Notes an amount in cash equal to the product of (i) outstanding
principal amount of such Convertible Note multiplied by (ii) .025 multiplied
by (iii) the quotient of (x) the number of days after the such default or
defaults have occurred, divided by (y) 30.  The Company shall make the payments
referred to in the immediately preceding sentence within ten days of the date
such payment accrued.  In the event the Company fails to make such payments
in a timely manner, such payments shall bear interest at the rate of 2.5% per
month (pro rated for partial months) until paid in full.

  Section 6.16. Transactions With Affiliates. So long as (i) any shares of
Convertible Notes or Substitute Warrants are outstanding or (ii) any Investor
owns Conversion Shares and/or Warrant Shares  with a market value equal to or
greater than $500,000, the Company shall not, and shall cause each of its
Subsidiaries not to, enter into, amend, modify or supplement, or permit any
Subsidiary to enter into, amend, modify or supplement, any agreement,
transaction, commitment or arrangement with any of its or any Subsidiary's
officers, directors, persons who were officers or directors at any time during
the previous two years, stockholders who beneficially own 5% or more of the
Common Stock, or affiliates or with any individual related by blood, marriage
or adoption to any such individual or with any entity in which any such entity
or individual owns a 5% or more beneficial interest (each a "Related Party"),
except for (a) customary employment arrangements and benefit programs on
reasonable terms, (b) any agreement, transaction, commitment or arrangement
on an arm's-length basis on terms no less favorable than terms which would
have been obtainable from a person other than such Related Party, or (c) any
agreement, transaction, commitment or arrangement which is approved by a
majority of the disinterested directors of the Company.  For purposes hereof,
any director who is also an officer of the Company or any Subsidiary of the
Company shall not be a disinterested director with respect to any such
agreement, transaction, commitment or arrangement.  "Affiliate" for purposes
of this Section means, with respect to any Person, another Person that,
directly or indirectly, (i) has a 5% or more equity interest in that Person,
(ii) has 5% or more common ownership with that Person, (iii) controls that
Person, or (iv) shares common control with that Person.  "Control" or
"controls" for purposes of this Agreement  means that a Person has the power,
direct or indirect, to conduct or govern the policies of another Person.

  Section 6.17. Filing of Form 8-K. On or before the second (2nd) business day
following the Closing Date, the Company shall file a Form 8-K with the SEC
attaching the Transaction Documents and otherwise in the form required by the
Exchange Act.


ARTICLE VII

Survival; Indemnification

  Section 7.1.  Survival.  The representations, warranties and covenants made
by each of the Company and each Investor in this Agreement, the annexes,
schedules and exhibits hereto and in each instrument, agreement and
certificate entered into and delivered by them pursuant to this Agreement,
shall survive the Closing and the consummation of the transactions contemplated
hereby.  In the event of a breach or violation of any of such representations,
warranties or covenants, the party to whom such representations, warranties
or covenants have been made shall have all rights and remedies for such breach
or violation available to it under the provisions of this Agreement,
irrespective of any investigation made by or on behalf of such party on or
prior to the Closing Date.

  Section 7.2.  Indemnity.  The Company shall indemnify and hold harmless the
Investors, their respective Affiliates and their respective officers,
directors, partners and members (each an "Indemnified Party"), from and
against any and all Damages, and shall reimburse the Indemnified Parties for
all reasonable out-of-pocket expenses (including the reasonable fees and
expenses of legal counsel), in each case promptly as incurred by such
Indemnified Party and to the extent arising out of or in connection with:

  (i) any misrepresentation, omission of fact or breach of any of the Company's
      representations or warranties contained in any of the Transaction
      Documents or the Convertible Notes, the annexes, schedules or exhibits
      thereto or any instrument, agreement or certificate entered into or
      delivered by the Company pursuant hereto or thereto; or

 (ii) any failure by the Company to perform in any material respect any of
      its covenants, agreements, undertakings or obligations set forth in any
      of the Transaction Documents or the Convertible Notes, the annexes,
      schedules or exhibits thereto or any instrument, agreement or
      certificate entered into or delivered by the Company pursuant hereto or
      thereto; or

(iii) any action instituted against the Investors, or any of them, by any
      stockholder of the Company who is not an Affiliate of an Investor, with
      respect to any of the transactions contemplated by the Transaction
      Documents.

  Section 7.3.  Notice.  Promptly after receipt by an Indemnified Party
seeking indemnification pursuant to Section 7.2 of written notice of any
investigation, claim, proceeding or other action in respect of which
indemnification is being sought (each, a "Claim"), the Indemnified Party
promptly shall notify the Company of the commencement thereof; but the
omission so to notify the Company shall not relieve it from any liability
that it otherwise may have to the Indemnified Party, except to the extent
that the Company is actually prejudiced by such omission or delay. In
connection with any Claim as to which both the Indemnified Party and the
Company are parties, the Company shall be entitled to assume the defense
thereof.  Notwithstanding the assumption of the defense of any Claim by the
Company, the Indemnified Party shall have the right to employ separate legal
counsel and to participate in the defense of such Claim, and the Company shall
bear the reasonable fees, out-of-pocket costs and expenses of such separate
legal counsel to the Indemnified Party if (and only if): (x) the Company shall
have agreed to pay such fees, out-of-pocket costs and expenses, (y) the
Indemnified Party reasonably shall have concluded that representation of the
Indemnified Party and the Company by the same legal counsel would not be
appropriate due to actual or, as reasonably determined by legal counsel to
the Indemnified Party, potentially differing interests between such parties in
the conduct of the defense of such Claim, or if there may be legal defenses
available to the Indemnified Party that are in addition to or disparate from
those available to the Company, or (z) the Company shall have failed to
employ legal counsel reasonably satisfactory to the Indemnified Party within
a reasonable period of time after notice of the commencement of such Claim.
If the Indemnified Party employs separate legal counsel in circumstances other
than as described in clauses (x), (y) or (z) above, the fees, costs and
expenses of such legal counsel shall be borne exclusively by the Indemnified
Party.  Except as provided above, the Company shall not, in connection with
any Claim in the same jurisdiction, be liable for the fees and expenses of
more than one firm of legal counsel for the Indemnified Party (together with
appropriate local counsel).  The Company shall not, without the prior written
consent of the Indemnified Party (which consent shall not unreasonably be
withheld), settle or compromise any Claim or consent to the entry of any
judgment that does not include an unconditional release of the Indemnified
Party from all liabilities with respect to such Claim or judgment.

  Section 7.4.  Direct Claims.  In the event an Indemnified party should have
a claim for indemnification that does not involve a claim or demand being
asserted by a third party, the Indemnified Party promptly shall deliver notice
of such claim to the Company.  If the Company disputes the claim, such dispute
shall be resolved by mutual agreement of the Indemnified Party and the Company
or by binding arbitration conducted in accordance with the procedures and
rules of the American Arbitration Association as set forth in Article X.
Judgment upon any award rendered by any arbitrators may be entered in any
court having competent jurisdiction thereof.


ARTICLE VIII

Due Diligence Review; Non-Disclosure of Non-Public Information.

  Section 8.1.  Due Diligence Review.  Subject to Section 8.2, the Company
shall make available for inspection and review by the Investors, advisors to
and representatives of the Investors (who may or may not be affiliated with
the Investors and who are reasonably acceptable to the Company), any
underwriter participating in any disposition of the Registrable Securities on
behalf of the Investors pursuant to the Registration Statement, any such
registration statement or amendment or supplement thereto or any blue sky,
Nasdaq  or other filing, all SEC Documents and other filings with the SEC,
and all other publicly available corporate documents and properties of the
Company as may be reasonably necessary for the purpose of such review, and
cause the Company's officers, directors and employees to supply all such
publicly available information reasonably requested by the Investors or any
such representative, advisor or underwriter in connection with such
Registration Statement (including, without limitation, in response to all
questions and other inquiries reasonably made or submitted by any of them),
prior to and from time to time after the filing and effectiveness of the
Registration Statement for the sole purpose of enabling the Investors and
such representatives, advisors and underwriters and their respective
accountants and attorneys to conduct initial and ongoing due diligence with
respect to the Company and the accuracy of the amendment to the Registration
Statement.

  Section 8.2.  Non-Disclosure of Non-Public Information.

  (a) The Company shall not disclose material non-public information to the
      Investors, advisors to or representatives of the Investors unless prior
      to disclosure of such information the Company identifies such information
      as being non-public information and provides the Investors, such advisors
      and representatives with the opportunity to accept or refuse to accept
      such non-public information for review.  Other than disclosure of any
      comment letters received from the SEC staff with respect to an amendment
      to the Registration Statement, the Company may, as a condition to
      disclosing any non-public information hereunder, require the Investors'
      advisors and representatives to enter into a confidentiality agreement
      in form and content reasonably satisfactory to the Company and the
      Investors.

  (b) Nothing herein shall require the Company to disclose material non-public
      information to the Investors or their advisors or representatives, and
      the Company represents that it does not disseminate material non-public
      information to any investors who purchase stock in the Company in a
      public offering, to money managers or to securities analysts; provided,
      however, that notwithstanding anything herein to the contrary, the
      Company will, as hereinabove provided, promptly notify the advisors and
      representatives of the Investors and, if any, underwriters, of any event
      or the existence of any circumstance (without any obligation to disclose
      the specific event or circumstance) of which it becomes aware,
      constituting material non-public information (whether or not requested
      of the Company specifically or generally during the course of due
      diligence by such persons or entities), which, if not disclosed in the
      prospectus included in the amendment to the Registration Statement would
      cause such prospectus to include a material misstatement or to omit a
      material fact required to be stated therein in order to make the
      statements therein, in light of the circumstances in which they were
      made, not misleading. Nothing contained in this Section 8.2 shall be
      construed to mean that such persons or entities other than the Investors
      (without the written consent of the Investors prior to disclosure of such
      information as set forth in Section 8.2(a)) may not obtain non-public
      information in the course of conducting due diligence in accordance with
      the terms of this Agreement and nothing herein shall prevent any such
      persons or entities from notifying the Company of their opinion that
      based on such due diligence by such persons or entities, that the
      Registration Statement contains an untrue statement of a material fact or
      omits a material fact required to be stated in the Registration Statement
      or necessary to make the  statements contained therein, in light of the
      circumstances in which they were made, not misleading.


ARTICLE IX

Legends; Transfer Agent Instructions

  Section 9.1.  Legends.  Unless otherwise provided below, each certificate
representing Registrable Securities will bear the following legend or
equivalent (the "Legend"):

THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY
OTHER APPLICABLE SECURITIES LAWS AND HAVE BEEN ISSUED IN RELIANCE UPON AN
EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH
OTHER SECURITIES LAWS.  NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION
HEREIN MAY BE SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED, OR OTHERWISE
DISPOSED OF, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
SECURITIES ACT OR PURSUANT TO A TRANSACTION THAT IS EXEMPT FROM SUCH
REGISTRATION.

  Section 9.2.  Transfer Agent Instructions.  Upon the execution and delivery
hereof, the Company is issuing to the transfer agent for its Common Stock
(and shall issue to any substitute or replacement transfer agent for its
Common Stock upon the Company's appointment of any such substitute or
replacement transfer agent) Irrevocable Transfer Agent Instructions
substantially in the form of Exhibit F hereto.  Such Irrevocable Transfer
Agent Instructions shall be irrevocable by the Company from and after the
date hereof or from and after the issuance thereof to any such substitute or
replacement transfer agent, as the case may be.

  Section 9.3.  No Other Legend or Stock Transfer Restrictions.  No legend
other than the one specified in Section 9.1 has been or shall be placed on
the share certificates representing the Registrable Securities and no
instructions or "stop transfer orders," "stock transfer restrictions," or
other restrictions have been or shall be given to the Company's transfer
agent with respect thereto other than as expressly set forth in this Article
IX.

  Section 9.4.  Investors' Compliance.  Nothing in this Article shall affect
in any way each Investor's obligations to comply with all applicable
securities laws upon resale of the Common Stock.

  Section 9.5.  Transfers without Registration.  If an Investor provides the
Company with an opinion of counsel, in generally acceptable form, that
registration of a resale by such Investor of any Securities is not required
under the Securities Act, the Company shall permit the transfer and, in the
case of the Conversion Shares, promptly instruct its transfer agent to issue
one or more certificates in such name and in such denominations as specified
by such Investor and, if such opinion provides that such legends can be
removed,  without any restrictive legends.

  Section 9.6.  Injunctive Relief.  The Company acknowledges that a breach by
it of its obligations hereunder will cause irreparable harm to the Investors
by vitiating the intent and purpose of the transaction contemplated hereby.
Accordingly, the Company acknowledges that the remedy at law for a breach of
its obligations under this Article IX will be inadequate and agrees, in the
event of a breach or threatened breach by the Company of the provisions of
this Article IX, that the Investors shall be entitled, in addition to all
other available remedies, to an injunction restraining any breach and requiring
immediate issuance and transfer, without the necessity of showing economic
loss and without any bond or other security being required.

ARTICLE X

Choice of Law; Arbitration

  Section 10.1. Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of New York applicable to
contracts made in New York by persons domiciled in New York City and without
regard to its principles of conflicts of laws ; provided, however, that the
corporate laws of the State of Delaware shall govern all issues concerning
the relative rights of the Company and its stockholders.

  Section 10.2. Arbitration.  Any dispute under this Agreement shall be
submitted to arbitration under the rules of the American Arbitration
Association (the "AAA") in New York, New York, and shall be finally and
conclusively determined by the decision of a board of arbitration consisting
of three (3) members (hereinafter referred to as the "Board of Arbitration")
selected according to the rules governing the AAA.  The Board of Arbitration
shall meet on consecutive business days in New York, New York, and shall reach
and render a decision in writing (concurred in by a majority of the members of
the Board of Arbitration) with respect to the amount, if any, which the losing
party is required to pay to the other party in respect of a claim filed.  In
connection with rendering its decisions, the Board of Arbitration shall adopt
and follow the laws of the State of New York unless the matter at issue is the
corporation law of the company's state of incorporation, in which event the
corporation law of such jurisdiction shall govern such issue.  To the extent
practical, decisions of the Board of Arbitration shall be rendered no more
than thirty (30) calendar days following commencement of proceedings with
respect thereto.  The Board of Arbitration shall cause its written decision
to be delivered to all parties involved in the dispute.  Any decision made by
the Board of Arbitration (either prior to or after the expiration of such
thirty (30) calendar day period) shall be final, binding and conclusive on the
parties to the dispute, and entitled to be enforced to the fullest extent
permitted by law and entered in any court of competent jurisdiction. The Board
of Arbitration shall be authorized and is hereby directed to enter a default
judgment against any party failing to participate in any proceeding hereunder
within the time periods set forth in the AAA rules. The non-prevailing party
to any arbitration (as determined by the Board of Arbitration) shall pay the
expenses of the prevailing party, including reasonable attorneys' fees, in
connection with such arbitration. Any party shall be entitled to obtain
injunctive relief from a court in any case where such relief is available, and
the non-prevailing party to any such injunctive proceeding shall pay the
expenses of the prevailing party, including reasonable attorneys' fees, in
connection with such proceeding.

of, and be enforceable by, any permitted transferee of any Securities, and
(b) upon the prior written consent of the Company, which consent shall not
unreasonably be withheld or delayed, each Investor's interest in this Agreement
may be assigned at any time, in whole or in part, to any other Person
(including any Affiliate of the Investor) who agrees to make the
representations and warranties contained in Article III and who agrees to be
bound by the terms of this Agreement.

ARTICLE XIII

Miscellaneous

  Section 13.1. Counterparts/Facsimile/Amendments.  This Agreement may be
executed in multiple counterparts, each of which may be executed by fewer than
all of the parties and shall be deemed to be an original instrument that shall
be enforceable against the parties actually executing such counterparts and
all of which together shall constitute one and the same instrument.  Except
as otherwise stated herein, in lieu of the original documents, a facsimile
transmission or copy of the original documents shall be as effective and
enforceable as the original.  This Agreement may be amended only by a writing
executed by all parties.

  Section 13.2. Entire Agreement.  This Agreement, the other Transaction
Documents, which include, but are not limited to, the Substitute Warrants,
the Escrow Agreement, the Registration Rights Agreement and the Irrevocable
Transfer Agent Instructions, and the Convertible Notes set forth the entire
agreement and understanding of the parties relating to the subject matter
hereof and supersede all prior and contemporaneous agreements, negotiations
and understandings between the parties, both oral and written, relating to
the subject matter hereof.  The terms and conditions of all Exhibits to this
Agreement are incorporated herein by this reference and shall constitute part
of this Agreement as is fully set forth herein.

  Section 13.3. Severability.  In the event that any provision of this
Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable or void, this Agreement shall continue in full force
and effect without such provision; provided that such severability shall be
ineffective if it materially changes the economic benefit of this Agreement
to any party.

  Section 13.4. Headings.  The headings used in this Agreement are used for
convenience only and are not to be considered in construing or interpreting
this Agreement.

  Section 13.5. Number and Gender.  There may be one or more Investors parties
to this Agreement, which Investors may be natural persons or entities.  All
references to plural Investors shall apply equally to a single Investor if
there is only one Investor, and all references to an Investor as "it" shall
apply equally to a natural person.

  Section 13.6. Reporting Entity for the Common Stock.  The reporting entity
relied upon for the determination of the trading price or trading volume of
the Common Stock on any given Trading Day for the purposes of this Agreement
shall be Bloomberg, L.P. or any successor thereto. If, however, Bloomberg
L.P. does not report trades or bid prices for the Common Stock in the over-
the-counter market, then the reporting entity shall be the National Quotation
Bureau, Inc. The written agreement of the Investors and the Company shall be
required to employ any other reporting entities.

  Section 13.7. Replacement of Convertible Notes or Certificates.  Upon (i)
receipt of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of a Convertible Note or a certificate representing
any Securities and (ii) in the case of any such loss, theft or destruction of
such Convertible Note or certificate, upon delivery of an indemnity agreement
or security reasonably satisfactory in form to the Company (which shall not
include the posting of any bond) or (iii) in the case of any such mutilation,
on surrender and cancellation of such Convertible Note or certificate, the
Company at its expense will execute and deliver, in lieu thereof, a new
Convertible Note or certificate of like tenor.

  Section 13.8. Fees and Expenses.  Each of the Company and the Investors
agrees to pay its own expenses incident to the performance of its obligations
hereunder.

  Section 13.9. Brokerage.  Each of the parties hereto represents that it has
had no dealings in connection with this transaction with any finder or broker
who will demand payment of any fee or commission from the other party.  The
Company on the one hand, and the Investors, on the other hand, each agree to
indemnify the other against and hold the other harmless from any and all
liabilities to any person claiming brokerage commissions or finder's fees on
account of services purported to have been rendered on behalf of the
indemnifying party in connection with this Agreement or the transactions
contemplated hereby.

  Section 13.10. Publicity.  The Company agrees that it will not issue any
press release or other public announcement of the transactions contemplated
by this Agreement without the prior consent of the Investors, which shall not
be unreasonably withheld nor delayed by more than two (2) Trading Days from
their receipt of such proposed release.  No release shall name the Investors
without their express consent.

  Section 13.11. Further Assurances.  Each party shall do and perform, or
cause to be done and performed, all such further acts and things, and shall
execute and deliver all such other agreements, certificates, instruments and
documents, as the other party may reasonably request in order to carry out
the intent and accomplish the purposes of this Agreement and the consummation
of the transactions contemplated hereby.

  Section 13.12. Termination.  If the Closing shall not have occurred on or
before five (5) business days from the date hereof due to the Company's or an
Investor's failure to satisfy the conditions set forth in Article II above
(and the nonbreaching party's failure to waive such unsatisfied condition(s)),
the nonbreaching party shall have the option to terminate this Agreement with
respect to such breaching party at the close of business on such date without
liability of any party to any other party.

  Section 13.13. No Strict Construction.  The language used in this Agreement
will be deemed to be the language chosen by the parties to express their
mutual intent, and no rules of strict construction will be applied against
any party.

  Section 13.14. Remedies.  Each Investor and each holder of Securities shall
have all rights and remedies set forth in this Agreement, the other Transaction
Documents and the Convertible Notes and all rights and remedies which such
holders have been granted at any time under any other agreement or contract
and all of the rights which such holders have under any law.  Any person or
entity having any rights under any provision of this Agreement shall be
entitled to enforce such rights specifically (without posting a bond or other
security), to recover damages by reason of any breach of any provision of this
Agreement or the other Transaction Documents and to exercise all other rights
granted by law.

  Section 13.15. Payment Set Aside.  To the extent that the Company makes a
payment or payments to the Investors hereunder or pursuant to the Convertible
Notes or the Investors enforce or exercise their rights hereunder or
thereunder, and such payment or payments or the proceeds of such enforcement
or exercise or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside, recovered from, disgorged by or are
required to be refunded, repaid or otherwise restored to the Company, a
trustee, receiver or any other person or entity under any law (including,
without limitation, any bankruptcy law, state or federal law, common law or
equitable cause of action), then to the extent of any such restoration the
obligation or part thereof originally intended to be satisfied shall be
revived and continued in full force and effect as if such payment had not
been made or such enforcement or setoff had not occurred.

HAVE BEEN REGISTERED WITH THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION
OR THE SECURITIES COMMISSION OF ANY STATE OR UNDER THE SECURITIES ACT OF 1933,

ULTRADATA SYSTEMS, INCORPORATED

11.25% SENIOR SUBORDINATED SECURED CONVERTIBLE PROMISSORY NOTE


    THIS PROMISSORY NOTE ("Note") is issued by ULTRADATA SYSTEMS,
INCORPORATED,  a Delaware corporation (the "Company"), and is designated as
its 11.25% Senior Subordinated Secured Convertible Promissory Note.  This Note
has been issued by the Company pursuant to the terms of an Exchange Agreement,
dated as of August ___, 2001 (the "Exchange Agreement"), between the Company
and certain holders of the Company's Series A Convertible Preferred Stock (the
"Series A Stock").  All 11.25% Senior Subordinated Secured Convertible
Promissory Notes issued by the Company pursuant to the Exchange Agreement are
referred to herein as the "Convertible Notes".  Capitalized terms used in this
Note and not otherwise defined herein shall have the meanings ascribed to them
in the Exchange Agreement.


    FOR VALUE RECEIVED, the Company promises to pay to the order of __________,
or permitted assigns (the "Holder"), the principal sum of ______________ (US
$__________) Dollars, in equal monthly installments of principal and interest
of Thirty-Five Thousand US Dollars (US$35,000) each on September 1, 2001,
September 7, 2001, and October 1, 2001, and the Company shall pay installments
of Forty-Five Thousand US Dollars (US$45,000) each on the first day of each
month commencing November 1, 2001, until the principal balance of this Note
plus all accrued and unpaid interest and other amounts due hereunder are less
than the amount of such installment, and in one final installment payable on
the first day of the next month thereafter equal to the outstanding principal
balance of this Note, plus all accrued and unpaid interest thereon, plus all
other amounts due hereunder.  Interest shall accrue on the principal balance
outstanding from time to time at the rate of 11.25% per annum.  In addition,
one installment of interest equal to 10% of the outstanding principal balance
of this Note on June 1, 2002 shall accrue and be payable on June 1, 2002;
provided, however, that if the Company does not pay such installment of
interest on such date, the amount so accrued shall be added to the principal
balance of this Note and interest thereafter shall accrue on the principal
balance as so increased.  Except for the installment of interest that will
accrue on June 1, 2002, accrual of interest shall commence on the first day
after the date of initial issuance of this Note (the "Issuance Date") and
continue daily on the basis of a 360-day year until payment in full of the
principal amount of this Note has been made or duly provided for.  If any
payment date is not a business day in the State of New York, then such payment
shall be made on the next succeeding business day.  The principal amount of
this Note outstanding from time to time (the "Principal Amount") and accrued
interest on this Note is payable in United States dollars by wire transfer of
immediately available funds in such amount in accordance with the Holder's
written wire transfer instructions provided by the Holder to the Company from
time to time or, if no such instructions are provided, by delivery of a bank
check in such amount to the Holder at the address of the Holder appearing on
the Note Register required to be maintained under Section 14 hereof, or at
such other address as designated by the Holder in writing to the Company.
Such cash payments and the issuance of the required number of shares of Common
Stock upon conversion of this Note determined pursuant to the provisions of
Section 3 or Section 4 below shall constitute a payment of principal and
interest hereunder and shall satisfy and discharge the liability for principal
and interest on this Note to the extent of the sum represented by such cash
payment or the equivalent Conversion Amount (as defined in Section 3 below)
of such shares of Common Stock.  The Company may prepay all or any part of
the Principal Amount of this Note and accrued and unpaid interest thereon in
cash in increments of not less than $10,000 at any time at an amount equal to
110% of the amount to be prepaid, it being understood that each $11,000 paid
shall be applied to pay $10,000 of principal and accrued and unpaid interest.
The Company shall have the right to apply any amounts so prepaid in cash to
reduce pro tanto any installment of interest and principal subsequently due
after such prepayment by giving written notice thereof by facsimile to the
Holder not later than the business day before the day on which such
installment is due and payable.  All payments, whether in cash or by
application of the Conversion Amount to make such payment, shall be applied
first to amounts payable hereunder other than principal or interest, then to
accrued and unpaid interest on the Principal Amount of this Note, and then to
reduce the Principal Amount of this Note.  Notwithstanding the Holder's
conversion of any portion of the Principal Amount of this Note, the Company
shall continue to pay the monthly cash installments due hereunder until
payment in full of the entire Principal Amount of this Note.

    This Note is subject to the following additional provisions:

    1. Withholding and Issuance Taxes.  The Company shall be entitled to
       withhold from all payments of principal of, and interest on, this Note
       any amounts required to be withheld under the applicable provisions of
       the United States income tax laws or other applicable laws at the time
       of such payments, and Holder shall execute and deliver all required
       documentation in connection therewith.  The issuance of certificates
       for shares of Common Stock upon conversion of this Note shall be made
       without charge to the Holder for any United States issuance tax in
       respect thereof, provided that the Company shall not be required to
       pay any tax that may be payable in respect of any transfer involved in
       the issuance and delivery of any certificate in a name other than that
       of the Holder of this Note.

    2. Transfer of Note.  This Note has been issued subject to investment
       representations of the original purchaser hereof and may be transferred
       or exchanged only in compliance with the Securities Act of 1933, as
       amended (the "Securities Act"), and other applicable state and foreign
       securities laws.  The Holder shall deliver written notice to the Company
       of any proposed transfer of this Note.  In the event of any proposed
       transfer of this Note, the Company may require, prior to issuance of a
       new Note in the name of such other person, that it receive reasonable
       transfer documentation including legal opinions that the issuance of the
       Note in such other name does not and will not cause a violation of the
       Securities Act or any applicable state or foreign securities laws.
       Prior to due presentment for transfer of this Note, the Company and any
       agent of the Company may treat the person in whose name this Note is duly
       registered on the Company's Note Register as the owner hereof for the
       purpose of receiving payment as herein provided and for all other
       purposes, whether or not this Note be overdue, and neither the Company
       nor any such agent shall be affected by notice to the contrary.

    3. Conversion.  The Holder of this Note is entitled, at its option, to
       convert at any time, the Principal Amount of this Note or any portion
       thereof, together with accrued and unpaid interest on such Principal
       Amount, into shares of Common Stock at any time as follows:

       (a) Right to Convert.

          (i) Subject to the terms, conditions, and restrictions of this
          Section 3, at any time after the Issuance Date, the Holder of this
          Note shall have the right to convert all or any portion of the
          Principal Amount of this Note, together with the accrued and unpaid
          interest on such Principal Amount so converted, into that number of
          fully paid and nonassessable shares of Common Stock (rounded to the
          nearest whole share in accordance with Subsection 3(e)), at the
          Conversion Rate (as defined below).

          (ii) Anything in Subsection 3(a)(i) to the contrary notwithstanding,
          in no event shall any Holder be entitled to convert all or any
          portion of the Principal Amount of this Note in excess of that
          amount of the Principal Amount of this Note that, upon giving effect
          to such conversion, would cause the aggregate number of shares of
          Common Stock beneficially owned by the Holder and its "affiliates"
          (as defined in Rule 405 under the Securities Act) to exceed 9.99% of
          the outstanding shares of the Common Stock following such conversion.
          For purposes of this Subsection, the aggregate number of shares of
          Common Stock beneficially owned by the Holder and its affiliates
          shall include the number of shares of Common Stock issuable upon
          conversion of this Note  with respect to which the determination is
          being made, but shall exclude the number of shares of Common Stock
          that would be issuable upon (i) conversion of the remaining,
          nonconverted portion of the Principal Amount of this Note
          beneficially owned by the Holder and its affiliates and (ii)
          exercise or conversion of the unexercised or unconverted portion of
          any other securities of the Company (including, without limitation,
          any warrants or convertible preferred stock) subject to a limitation
          on conversion or exercise analogous to the limitation contained
          herein beneficially owned by the Holder and its affiliates.  Except
          as set forth in the preceding sentence, for purposes of this
          Subsection 3(a)(ii), beneficial ownership shall be calculated in
          accordance with Section 13(d) of the Securities Exchange Act of
          1934, as amended (the "Exchange Act").  For purposes of this
          Subsection, in determining the number of outstanding shares Common
          Stock, the Holder may rely on the number of outstanding shares of
          Common Stock as reflected in (1) the Company's most recent Form
          10-QSB or Form 10-KSB, as the case may be, (2) a more recent public
          announcement by the Company or (3) any other notice by the Company
          or its transfer agent setting forth the number of shares of Common
          Stock outstanding.  For any reason at any time, upon the written or
          oral request of a Holder, the Company shall immediately confirm
          orally and in writing to any such Holder the number of shares Common
          Stock then outstanding.  In any case, the number of outstanding
          shares Common Stock shall be determined  after giving effect to
          conversions of this Note by such Holder since the date as of which
          such number of outstanding shares of Common Stock was reported. To
          the extent that the limitation contained in this Subsection 3(a)
          (ii) applies, the determination of whether such portion of the
          Principal Amount of this Note is convertible (in relation to other
          securities owned by a Holder) and of what portion of the Principal
          Amount of this Note is convertible shall be in the sole discretion
          of such Holder, and the submission of this Note for conversion shall
          be deemed to be such Holder's determination of whether such portion
          of the Principal Amount of this Note is convertible (in relation to
          other securities owned by such Holder) and of what portion of this
          Note is convertible, in each case subject to such aggregate
          percentage limitation, and the Company shall have no obligation or
          right to verify or confirm the accuracy of such determination.
          Nothing contained herein shall be deemed to restrict the right of a
          Holder to convert such portion of the Principal Amount of this Note
          at such time as  such conversion will not violate the provisions of
          this Subsection. A Holder of this Note may waive the provisions of
          this Subsection 3(a)(ii) as to itself (and solely as to itself)
          upon not less than 75 days' prior notice to the Company, and the
          provisions of this Subsection 3(a)(ii) shall continue to apply until
          such 75th day (or such later date as may be specified in such notice
          of waiver). No conversion in violation of this Subsection 3(a)(ii),
          but otherwise in accordance with this Note, shall affect the status
          of the Common Stock issued upon such conversion as validly issued,
          fully-paid and nonassessable. Subsection 3(i) below set forth
          additional limitations on the Company's obligation to issue shares
          of Common Stock upon conversion of this Note.

       (b) Conversion Rate and Other Definitions.  The number of shares of
       Common Stock issuable upon conversion of all or any portion of the
       Principal Amount of this Note pursuant to Subsection (3)(a) shall be
       determined according to the following formula (the "Conversion Rate"):

			Conversion Amount
			Conversion Price


        For purposes of this Note, the following terms shall have the following
        meanings:

       "Base Price" means, with respect to any portion of this Note, $3.50,
        as adjusted from time to time in accordance with Section 3(f) below.

       "Closing Bid Price" or "Closing Ask Price" means, for any security
        as of any date, the last closing bid or ask price, as the case may
        be, for such security on the Principal Market as reported by
        Bloomberg Financial Markets ("Bloomberg"), or, if the Principal
        Market is not the principal securities exchange or trading market
        for such security, the last closing bid or ask price of such
        security on the principal securities exchange or trading market
        where such security is listed or traded as reported by Bloomberg,
        or if the foregoing do not apply, the last closing bid or ask price
        of such security in the over-the-counter market on the electronic
        bulletin board for such security as reported by Bloomberg, or, if
        no closing bid or ask price is reported for such security by
        Bloomberg, the last closing trade price of such security as
        reported by Bloomberg, or, if no last closing trade price is
        reported for such security by Bloomberg, the average of the bid
        or ask prices of any market makers for such security as reported in
        the "pink sheets" by the National Quotation Bureau, Inc.  If the
        Closing Bid Price or Closing Ask Price cannot be calculated for
        such security on such date on any of the foregoing bases, the
        Closing Bid Price or Closing Ask Price of such security on such
        date shall be the fair market value as mutually determined by the
        Company and the holders of a majority of the currently outstanding
        Principal Amount of all Convertible Notes.  If the Company and the
        Holders of the Convertible Notes are unable to agree upon the fair
        market value of the Common Stock, then such dispute shall be
        resolved pursuant to Subsection 3(h).  (All such determinations to
        be appropriately adjusted for any stock dividend, stock, split or
        other similar transaction during such period).

       "Conversion Amount" means the amount of interest accrued on the
        outstanding Principal Amount of this Note plus any portion of the
        outstanding Principal Amount being converted as specified in a
        Conversion Notice (as defined in Subsection 3(c)).

       "Conversion Price" means, as of any Conversion Date or other date
        of determination, the lower of  the (x) Base Price, and (y) 70% of
        the average of the Closing Bid Prices in the five (5) Trading Days
        immediately preceding such Conversion Date or 75% of such average
        at any time hereafter when the Common Stock is listed on the Nasdaq
        Stock Market.

       "Principal Market" means the over-the-counter market.

       "Registration Rights Agreement" means that certain registration
        rights agreement between the Company and the initial holders of the
        Convertible Notes concerning the registration of the resale of the
        shares of Common Stock issuable upon conversion of such Convertible
        Notes.

       "Trading Day" means any day during which the Principal Market shall
        be open for business.

       (c)  Conversion Notice. The Holder of this Note may exercise its
       conversion right by giving a written conversion notice in the form of
       Exhibit A hereto (the "Conversion Notice") (x) by facsimile to the
       Company confirmed by a telephone call or (y) by registered mail or
       overnight delivery service, with a copy by facsimile to the Company's
       transfer agent for its Common Stock, as designated by the Company from
       time to time (the "Transfer Agent") and to its counsel, as designated
       by the Company from time to time.  If such conversion will result in
       the conversion of all of all remaining amounts due under this Note,
       the Holder shall also surrender this Note to the Company at its
       principal office (or such other office or agency of the Company may
       designate by notice in writing to the Holder) at any time during its
       usual business hours on the date set forth in the Conversion Notice.

       (d) Issuance of Certificates; Time Conversion Effected.

           (i) Promptly, but in no event more than three (3) Trading Days,
           after the receipt of the Conversion Notice referred to in
           Subsection 3(c) and surrender of this Note (if required), the
           Company shall issue and deliver, or the Company shall cause to be
           issued and delivered, to the Holder, registered in such name or
           names as the Holder may direct, a certificate or certificates for
           the number of whole shares of Common Stock into which this Note
           has been converted.  In the alternative, if the Company's Transfer
           Agent is a participant in the electronic book transfer program, the
           Transfer Agent shall credit such aggregate number of shares of
           Common Stock to which the Holder shall be entitled to the Holder's
           or its designee's balance account with The Depository Trust Company.
           Such conversion shall be deemed to have been effected, and the
           Conversion Date shall be deemed to have occurred, on the date on
           which such Conversion Notice shall have been received by the Company
           and at the time specified stated in such Conversion Notice, which
           must be during the calendar day of such notice.  The rights of the
           Holder of this Note shall cease, and the person or persons in whose
           name or names any certificate or certificates for shares of Common
           Stock shall be issuable upon such conversion shall be deemed to have
           become the holder or holders of record of the shares represented
           thereby, on the Conversion Date.  Issuance of shares of Common Stock
           issuable upon conversion that are requested to be registered in a
           name other than that of the registered Holder shall be subject to
           compliance with all applicable federal and state securities laws.

           (ii) The Company understands that a delay in the issuance of the
           shares of Common Stock beyond three (3) Trading Days after the
           Conversion Date could result in economic loss to the Holder of this
           Note.  As compensation to the Holder for such loss, the Company
           agrees to pay late payments to the Holder for late issuance of shares
           of Common Stock upon conversion in accordance with the following
           schedule (where "No. Trading Days Late" means the number of Trading
           Days after three (3) Trading Days from the date of receipt by the
           Company of the Conversion Notice with electronic book entry transfer
           instructions if the Company's Transfer Agent participates in the DWAC
           System of the Depository Trust Company, or without electronic book
           entry transfer instructions if the Company's Transfer Agent does not
           participate in such DWAC System) to and including the date of the
           Holder's or its designees' receipt of such shares):

           No. Trading Days Late        Late Payment For Each $5,000 of

                                                             Trading Day
                                                             late after 10
                                                             Calendar Days

           The Company shall make all payments due under this Subsection
           3(d)(ii) in immediately available funds upon demand.  Nothing
           herein shall limit the Holder's right to pursue injunctive relief
           and/or actual damages for the Company's failure to issue and
           deliver Common Stock to the Holder as required by Subsection
           3(d)(i), including, without limitation, the Holder's actual losses
           occasioned by any "buy-in" of Common Stock necessitated by such
           late delivery.  Furthermore, in addition to any other remedies that
           may be available to the Holder, if the Company fails for any reason
           to effect delivery of such shares of Common Stock within five (5)
           Trading Days after the Conversion Date, the Holder will be entitled
           to revoke the relevant Conversion Notice by delivering a notice to
           such effect to the Company. Upon delivery of such notice of
           revocation, the Company and the Holder shall each be restored to
           their respective positions immediately prior to delivery of such
           Conversion Notice, except that the Holder shall retain the right
           to receive both the late payment amounts set forth above plus the
           actual cost of any "buy-in."

           (iii) If, at any time (a) the Company challenges, disputes or denies
           the right of the Holder to effect the conversion of this Note into
           Common Stock or otherwise dishonors or rejects, or causes the
           Transfer Agent to dishonor or reject, any Conversion Notice properly
           delivered in accordance with this Section 3 or (b) any third party
           who is not and has never been an affiliate of the Holder obtains a
           judgment or order from any court or public or governmental authority
           that denies, enjoins, limits, modifies, or delays the right of the
           Holder to effect the conversion of this Note into Common Stock, then
           the Holder shall have the right, by written notice to the Company,
           to require the Company to promptly redeem this Note in accordance
           with Section 4.  Under any of the circumstances set forth above, the
           Company shall indemnify the Holder against and hold it harmless from,
           and be responsible for the payment of, all costs and expenses of the
           Holder, including its reasonable legal fees and expenses, as and when
           incurred in disputing any such action or pursuing its rights
           hereunder (in addition to any other rights of the Holder). The
           Company shall not refuse to honor, or cause the Transfer Agent to
           refuse to honor, any Conversion Notice unless the Company or the
           Transfer Agent, as the case may be, has actually been enjoined by a
           court of competent jurisdiction from doing so, and if so enjoined,
           the Company shall post with such court a performance bond equal to
           150% of the Conversion Amount of this Note sought to be converted by
           the Holder that are the subject of such injunction.

           (iv) The Holder of this Note shall be entitled to exercise its
           conversion privilege notwithstanding the commencement of any case
           under 11 U.S.C. Sec 101 et seq. (the "Bankruptcy Code").  The Company
           hereby waives to the fullest extent permitted any rights to relief it
           may have under 11 U.S.C. Sec 362 in respect of the Holder's
           conversion privilege, if the Company becomes a debtor under the
           Bankruptcy Code.  The Company agrees  to take or consent to any
           and all action necessary to effectuate relief under 11 U.S.C.
           Sec 362 without cost or expense to the Holder.

       (e) Fractional Shares.  The Company shall not, nor shall it cause the
           Transfer Agent to, issue any fraction of a share of Common Stock
           upon any conversion.  All shares of Common Stock (including
           fractions thereof) issuable upon conversion of any portion of
           the Principal Amount of this Note by the Holder shall be aggregated
           for purposes of determining whether the conversion would result in
           the issuance of a fraction of a share of Common Stock.  If, after
           such aggregation, the issuance would result in the issuance of a
           fraction of a share of Common Stock, the Company shall round, or
           cause the Transfer Agent to round, such fraction of a share of
           Common Stock up to the nearest whole share.

       (f) Adjustment to Conversion Price; Dilution and Other Events.  In
           order to prevent dilution of the rights granted under this Note,
           the Conversion Price will be subject to adjustment from time to
           time as provided in this Subsection 3(f).

           (i) Adjustment of Base Price upon Issuance of Common Stock.  If the
           Company issues or sells, or is deemed to have issued or sold, any
           shares of Common Stock (other than Conversion Shares (as defined in
           the Exchange Agreement) and shares of Common Stock deemed to have
           been issued by the Company in connection with Approved Issuances
           (as defined below)) for a consideration per share less than the
           Base Price (an "Offering") as in effect immediately prior to such
           time (the "Applicable Price"), then immediately after such issue or
           sale, the Base Price shall be reduced to an amount equal to (x) the
           product of the Base Price in effect immediately prior to such issue
           or sale and (y) the quotient determined by dividing (1) the sum of
           (I) the product of the Applicable Price and the number of shares of
           Common Stock Deemed Outstanding (as defined below) immediately prior
           to such issue or sale, and (II) the consideration, if any, received
           by the Company upon such issue or sale by (2) the product of (I) the
           Applicable Price and (II) the number of shares of Common Stock
           Deemed Outstanding immediately after such issuance or sale.  For
           purposes of determining the adjusted Base Price under this
           Subsection 3(f)(i), the following shall be applicable:

           (A) Issuance of Options.  If the Company in any manner grants any
               rights or options to subscribe for or to purchase Common Stock
               (other than in connection with an Approved Issuance or upon
               conversion of this Note) or any stock or other securities
               convertible into or exchangeable for Common Stock (such rights
               or options being herein called "Options" and such convertible or
               exchangeable stock or securities being herein called "Convertible
               Securities") and the price per share for which Common Stock is
               issuable upon the exercise of such Options or upon conversion
               or exchange of such Convertible Securities is less than the
               Applicable Price, then the total maximum number of shares of
               Common Stock issuable upon the exercise of such Options or
               upon conversion or exchange of the total maximum amount of such
               Convertible Securities issuable upon the exercise of such
               Options shall be deemed to be outstanding and to have been
               issued and sold by the Company for such price per share.  For
               purposes of this Subsection 3(f)(i)(A), the "price per share
               for which Common Stock is issuable upon exercise of such
               Options or upon conversion or exchange of such Convertible
               Securities" is determined by dividing (I) the total amount, if
               any, received or receivable by the Company as consideration
               for the granting of such Options, plus the minimum aggregate
               amount of additional consideration payable to the Company upon
               the exercise of all such Options, plus in the case of such
               Options which relate to Convertible Securities, the minimum
               aggregate amount of additional consideration, if any, payable
               to the Company upon the issuance or sale of such Convertible
               Securities and the conversion or exchange thereof, by (II) the
               total maximum number of shares of Common Stock issuable upon
               exercise of such Options or upon the conversion or exchange of
               all such Convertible Securities issuable upon the exercise of
               such Options. No adjustment of the Base Price shall be made
               upon the actual issuance of such Common Stock or of such
               Convertible Securities upon the exercise of such Options or
               upon the actual issuance of such Common Stock upon conversion
               or exchange of such Convertible Securities.  Notwithstanding
               the foregoing, no adjustment shall be made pursuant to this
               Subsection 3(f)(i)(A) to the extent that such adjustment is
               based solely on the fact that the Convertible Securities
               issuable upon exercise of such Option are convertible into or
               exchangeable for Common Stock  at a price that varies with the
               market price of the Common Stock.

           (B) Issuance of Convertible Securities.  If the Company in any
               manner issues or sells any Convertible Securities and the price
               per share for which Common Stock is issuable upon such conversion
               or exchange is less than the Applicable Price, then the maximum
               number of shares of Common Stock issuable upon conversion or
               exchange of such Convertible Securities shall be deemed to be
               outstanding and to have been issued and sold by the Company for
               such price per share.  For the purposes of this Subsection
               3(f)(i)(B), the "price per share for which Common Stock is
               issuable upon such conversion or exchange" is determined by
               dividing (I) the total amount received or receivable by the
               Company as consideration for the issue or sale of such
               Convertible Securities, plus the minimum aggregate amount of
               additional consideration, if any, payable to the Company upon
               the conversion or exchange thereof, by (II) the total maximum
               number of shares of Common Stock issuable upon the conversion
               or exchange of all such Convertible Securities.  No adjustment
               of the Base Price shall be made upon the actual issue of such
               Common Stock upon conversion or exchange of such Convertible
               Securities, and if any such issue or sale of such Convertible
               Securities is made upon exercise of any Options for which
               adjustment of the Base Price had been or are to be made
               pursuant to other provisions of this Subsection 3(f)(i), no
               further adjustment of the Base Price shall be made by reason
               of such issue or sale.  Notwithstanding the foregoing, no
               adjustment shall be made pursuant to this Subsection 3(f)(i)(B)
               to the extent that such adjustment is based solely on the fact
               that such Convertible Securities are convertible into or
               exchangeable for Common Stock at a price that varies with the
               market price of the Common Stock.

           (C) Change in Option Price or Rate of Conversion.  If the purchase
               price provided for in any Options, the additional consideration,
               if any, payable upon the issue, conversion or exchange of any
               Convertible Securities, or the rate at which any Convertible
               Securities are convertible into or exchangeable for Common Stock
               change at any time, the Base Price in effect at the time of such
               exchange shall be readjusted to the Base Price that would have
               been in effect at such time had such Options or Convertible
               Securities still outstanding provided for such changed purchase
               price, additional consideration or changed conversion rate, as
               the case may be, at the time initially granted, issued or sold;
               provided that no adjustment shall be made if such adjustment
               would result in an increase of the Base Price then in effect.

           (D) Certain Definitions.  For purposes of determining the adjusted
               Base Price under this Subsection 3(f)(i), the following terms
               have meanings set forth below:

               (I) "Approved Issuances" shall mean (i) the issuance of
               securities upon exercise or conversion of the Company's options,
               warrants or other convertible securities outstanding as of the
               date hereof, or (ii) the grant of additional options or warrants,
               or the issuance of additional securities, under any Company
               stock option plan, restricted stock plan, stock purchase plan
               or other plan or written compensation contract for the benefit
               of the Company's employees, directors or consultants in effect
               on the date hereof.

               (II) "Common Stock Deemed Outstanding" means, at any given time,
               the number of shares of Common Stock actually outstanding at
               such time, plus the number of shares of Common Stock deemed to
               be outstanding pursuant to Subsections 3(f)(i)(A) and 3(f)(i)(B)
               hereof regardless of whether the Options or Convertible
               Securities are actually exercisable at such time, but excluding
               any shares of Common Stock issuable upon conversion of the
               Convertible Notes.

           (E) Effect on Base Price of Certain Events.  For purposes of
               determining the adjusted Base Price under this Section 3(f),
               the following shall be applicable:

               (I) Calculation of Consideration Received.  If any Common Stock,
               Options or Convertible Securities are issued or sold or deemed
               to have been issued or sold for cash, the consideration received
               therefor will be deemed to be the amount received by the Company
               therefor, before deduction of reasonable commissions,
               underwriting discounts or allowances or other reasonable
               expenses paid or incurred by the Company in connection with
               such issuance or sale.  In case any Common Stock, Options or
               Convertible Securities are issued or sold for a consideration
               other than cash, the amount of the consideration other than cash
               received by the Company will be the fair value of such
               consideration, except where such consideration consists of
               securities, in which case the amount of consideration received
               by the Company will be the arithmetic average of the Closing
               Bid Prices of such security for the five consecutive Trading
               Days immediately preceding the date of receipt.  In case any
               Common Stock, Options or Convertible Securities are issued to
               the owners of the non-surviving entity in connection with any
               merger in which the Company is the surviving entity the amount
               of consideration therefor will be deemed to be the fair value
               of such portion of the net assets and business of the non-
               surviving entity as is attributable to such Common Stock,
               Options or Convertible Securities, as the case may be.  The
               fair value of any consideration other than cash or securities
               will be determined jointly by the Company and the holders
               constituting more than sixty-six and two-thirds percent
               (66-2/3%) of the Principal Amount of all Convertible Notes
               then outstanding.  If such parties are unable to reach agreement
               within ten (10) days after the occurrence of an event requiring
               valuation (the "Valuation Event"), the fair value of such
               consideration will be determined within forty-eight (48) hours
               of the tenth (10th) day following the Valuation Event by an
               independent, reputable appraiser selected by the Company. The
               determination of such appraiser shall be deemed binding upon
               all parties absent manifest error.

               (II) Integrated Transactions.  In case any Option is issued in
               connection with the issue or sale of other securities of the
               Company, together comprising one integrated transaction in
               which no specific consideration is allocated to such Options
               by the parties thereto, the Options will be deemed to have
               been issued for a consideration of $0.01.

               (III) Treasury Shares.  The number of shares of Common Stock
               outstanding at any given time does not include shares owned or
               held by or for the account of the Company, and the disposition of
               any shares so owned or held will be considered an issue or sale
               of Common Stock.

               (IV) Record Date.  If the Company takes a record of the holders
               of Common Stock for the purpose of entitling them (1) to receive
               a dividend or other distribution payable in Common Stock, Options
               or Convertible Securities or (2) to subscribe for or purchase
               Common Stock, Options or Convertible Securities, then such record
               date will be deemed to be the date of the issue or sale of the
               shares of Common Stock deemed to have been issued or sold upon
               the declaration of such dividend or the making of such other
               distribution or the date of the granting of such right of
               subscription or purchase, as the case may be.

           (ii) Adjustment of Base Price upon Subdivision or Combination of
           Common Stock.  If the Company at any time subdivides (by any stock
           split, stock dividend, recapitalization or otherwise) one or more
           classes of its outstanding shares of Common Stock into a greater
           number of shares, the Base Price in effect immediately prior to such
           subdivision will be proportionately reduced.  If the Company at any
           time combines (by combination, reverse stock split or otherwise) one
           or more classes of its outstanding shares of Common Stock into a
           smaller number of shares, the Base Price in effect immediately
           prior to such combination will be proportionately increased.

           (iii) Adjustment of Variable Conversion Price upon Issuance of
           Convertible Securities.  If the Company in any manner issues or
           sells Convertible Securities that are convertible into Common Stock
           at a price that varies with the market price of the Common Stock
           (the formulation for such variable price being herein referred to
           as, the "Variable Price") and such Variable Price is not calculated
           using the same formula used to calculate the Variable Conversion
           Price in effect immediately prior to the time of such issue or
           sale, the Company shall provide written notice thereof via facsimile
           and overnight courier to the Holder of this Note ("Variable Notice")
           on the date of issuance of such Convertible Securities.  If the
           Holder of this Note provides written notice via facsimile and
           overnight courier (the "Variable Price Election Notice") to the
           Company within five (5) business days of receiving a Variable
           Notice that the Holder desires to replace the Conversion Price
           then in effect with the Variable Price described in such Variable
           Notice, then from and after the date of the Company's receipt of
           the Variable Price Election Notice, the  Conversion Price will
           automatically be replaced with the Variable Price (together with
           such modifications to this Note as may be required to give full
           effect to the substitution of the Variable Price for the Variable
           Conversion Price). The Holder's delivery of a Variable Price
           Election Notice shall serve as the consent required to amend this
           Note.  In the event that the Holder delivers a Conversion Notice
           at any time after the Company's issuance  of Convertible Securities
           with a Variable Price but before the Holder's receipt of the
           Company's Variable Notice, then such Holder shall have the option
           by written notice to the Company to rescind such Conversion Notice
           or to have the Conversion Price be equal to such Variable Price for
           the conversion effected by such Conversion Notice.

           (iv) Reorganization, Reclassification, Consolidation, Merger or Sale.
           Any recapitalization, reorganization, reclassification,
           consolidation, merger, sale of all or substantially all of the
           Company's assets to another Person (as defined below) or other
           transaction which is effected in such a way that holders of Common
           Stock are entitled to receive (either directly or upon subsequent
           liquidation) stock, securities or assets with respect to or in
           exchange for Common Stock is referred to herein as an "Organic
           Change."  Prior to the consummation of any Organic Change, the
           Company will make appropriate provision (in form and substance
           reasonably satisfactory to the Holder) to insure that the Holder
           will thereafter have the right to acquire and receive in lieu of
           or in addition to (as the case may be) the shares of Common Stock
           otherwise acquirable and receivable upon the conversion of this
           Note, such shares of stock, securities or assets as would have been
           issued or payable in such Organic Change with respect to or in
           exchange for the number of shares of Common Stock that would have
           been acquirable and receivable had this Note been converted into
           shares of Common Stock immediately prior to such Organic Change
           (without taking into account any limitations or restrictions on
           the timing or amount of conversions).  In any such case, the
           Company will make appropriate provision (in form and substance
           reasonably satisfactory to the Holder) with respect to the Holder's
           rights and interests to insure that the provisions of this Section
           3(f) will thereafter be applicable to this Note (including, in the
           case of any such consolidation, merger or sale in which the
           successor entity or purchasing entity is other than the Company,
           an immediate adjustment of the Base Price in accordance with
           Subsection 3(f)(i) using the value for the Common Stock reflected
           by the terms of such consolidation, merger or sale, if the value
           so reflected is less than the Base Price in effect immediately
           prior to such consolidation, merger or sale).  The Company will
           not effect any such consolidation, merger or sale, unless prior
           to the consummation thereof, the successor entity (if other than
           the Company) resulting from consolidation or merger or the entity
           purchasing such assets assumes, by written instrument (in form and
           substance reasonably satisfactory to the holders of a more than
           sixty-six and two-thirds percent (66-2/3%) of Principal Amount of
           the Convertible Notes then outstanding), the obligation to deliver
           to each holder of Convertible Notes such shares of stock, securities
           or assets as, in accordance with the foregoing provisions, such
           holder may be entitled to acquire.  "Person" shall mean an
           individual, a limited liability company, a partnership, a joint
           venture, a corporation, a trust, an unincorporated organization and
           a government or any department or agency thereof.

           (v) Certain Events.  If any event occurs of the type contemplated by
           the provisions of this Subsection 3(f) but not expressly provided
           for by such provisions (including, without limitation, the granting
           of stock appreciation rights, phantom stock rights or other rights
           with equity features), then the Company's Board of Directors will
           make an appropriate adjustment in the Conversion Price so as to
           protect the rights of the Holder of this Convertible Note and the
           other holders of Convertible Notes; provided, however, that no such
           adjustment will increase the Conversion Price as otherwise determined
           pursuant to this Section 3(f).

       (g) Intentionally Omitted.

       (h) Dispute Resolution.  In the case of a dispute as to the determination
           of the Closing Ask Price or Closing Bid Price of any security or the
           arithmetic calculation of the Conversion Rate, the Company shall,
           or shall cause the Transfer Agent to, promptly issue to the Holder
           the number of shares of Common Stock that is not disputed and shall
           submit the disputed determinations or arithmetic calculations to
           the Holder via facsimile within one (1) business day of receipt of
           the Holder's Conversion Notice.  If the Holder and the Company are
           unable to agree upon the determination of such Closing Ask Price
           or Closing Bid Price, as the case may be, or arithmetic calculation
           of the Conversion Rate within one (1) business day of such disputed
           determination or arithmetic calculation being submitted to the
           Holder, then the Company shall within one (1) business day following
           such date of delivery submit via facsimile (A) the disputed
           determination of the Closing Ask Price or Closing Bid Price, as the
           case may be, to an independent, reputable investment bank or (B)
           the disputed arithmetic calculation of the Conversion Rate to its
           independent certified public accounting firm.  The Company shall
           cause the investment bank or the accounting firm, as the case may
           be, to perform the determinations or calculations and notify the
           Company and the Holder of the results no later than forty-eight
           (48) hours from the time it receives the disputed determinations
           or calculations.  Such investment bank's or accounting firm's
           determination or calculation, as the case may be, shall be binding
           upon all parties absent manifest error.

           (i) Conversion Cap.  Except as otherwise provided herein, the
           Company shall not be required to issue any shares of Common Stock
           upon conversion of the Convertible Notes in any rolling 90-calendar
           day period, collectively and in the aggregate, in excess of 20%
           of the cumulative trading volume of the Corporation's Common Stock
           for the sixty-six (66) Trading Days prior to and including the date
           of conversion as reported by Bloomberg (the "Conversion Cap").  The
           Holder shall not be issued, upon conversion of its Note, shares of
           Common Stock in an amount greater than the product of (x) the
           Conversion Cap amount multiplied by (y) a fraction, the numerator
           of which is the Principal Amount of this Note and the denominator
           of which is the aggregate Principal Amount of all Convertible Notes
           issued to the holders thereof pursuant to the Exchange Agreement
           (the "90-Day Cap Allocation Amount").  In the event that the Holder
           shall sell or otherwise transfer this Note, or any interest therein,
           the transferee shall be allocated a pro rata portion of such
           Holder's 90-Day Cap Allocation Amount.  In the event that the Holder
           shall convert the entire Principal Amount of this Note into a number
           of shares of Common Stock that, in the aggregate, is less than such
           holder's 90-Day Cap Allocation Amount, then the difference between
           such holder's 90-Day Cap Allocation Amount and the number of shares
           of Common Stock actually issued to such Holder shall be allocated
           to the respective 90-Day Cap Allocation Amounts of the remaining
           holders of the Convertible Notes on a pro rata basis in proportion
           to the Principal Amount of Convertible Notes then held by each
           such holder.

    4. Redemption of this Note.

       (a) Intentionally Omitted.

       (b) Mandatory Redemption.

           (i) Holder's Option if Company Cannot Fully Convert or Holder Cannot
           Sell Without Restriction.  If upon the Company's receipt of a
           Conversion Notice, the Company fails to issue shares of Common Stock
           as contemplated by Subsection 3(d)(iii) or cannot issue shares of
           Common Stock registered for resale under the registration statement
           required to be filed under the Registration Rights Agreement with
           respect to the shares of Common Stock issuable upon conversion of
           this Note (the "Registration Statement") (or which are exempt
           from the registration requirements under the Securities Act
           pursuant to Rule 144(k) under the Securities Act) for any reason,
           including, without limitation, because the Company (x) does not
           have a sufficient number of shares of Common Stock authorized and
           available, (y) is otherwise prohibited by applicable law or by the
           rules or regulations of any stock exchange, interdealer quotation
           system or other self-regulatory organization with jurisdiction over
           the Company or its securities, including without limitation the
           Exchange Cap, from issuing all of the Common Stock that is to be
           issued to the Holder of this Note pursuant to a Conversion Notice
           or (z) fails to have a sufficient number of shares of Common Stock
           registered for resale under the Registration Statement, then (A)
           the Company shall, or shall cause the Transfer Agent to, issue as
           many shares of Common Stock as it is able to issue in accordance
           with such holder's Conversion Notice (if the Holder shall have
           given such a Conversion Notice) and pursuant to Section 3(d), and
           (B) with respect to all or any part of the unconverted Principal
           Amount of this Note plus accrued and unpaid interest thereon, the
           Holder, solely at such Holder's option, can elect to:

           (A) require the Company to redeem from such Holder all or any part
               of its remaining Principal Amount of this Note plus accrued
               and unpaid interest thereon ("Redemption") at an amount equal
               to the greater of (I) the sum of: (a)  100% of such Principal
               Amount plus (b) the accrued and unpaid interest thereon or
               (II) the product of (a) the Conversion Rate on the date of
               such Holder's delivery of an Election Response Notice (as
               defined below) and (b) the greater of (i) the 5 day average
               Closing Ask Price of the Common Stock on the Trading Day
               immediately preceding the event giving rise to Redemption or
               (ii) the Closing Ask Price of the Common Stock on the date of
               the Holder's delivery to the Company of an Election Response
               Notice or a Notice of Redemption (as such terms are defined
               below) or, if such date of delivery is not a Trading Day,
               the next date on which the exchange or market on which the
               Common Stock is traded is open (the "Redemption Price");

           (B) if the Company's inability to fully convert this Note is
               pursuant to clause (z) above of this Subsection 4(b)(i), require
               the Company to, or cause the Transfer Agent to, issue restricted
               shares of Common Stock in accordance with such Holder's
               Conversion Notice and pursuant to Section 3(d);

           (C) void its Conversion Notice and retain the Principal Amount of
               this Note plus accrued and unpaid interest thereon that was to be
               converted pursuant to such Holder's Conversion Notice (provided
               that the Holder's voiding its Conversion Notice shall not affect
               the Company's obligations to make any payments which have
               accrued prior to the date of such notice); or

           (D) if the Company's inability to fully convert this Note is
               pursuant to clause (y) above of this Subsection 4(b)(i),
               require the Company to, or cause the Transfer Agent to, issue
               shares of Common Stock in accordance with such Holder's
               Conversion Notice and pursuant to Section 4(d) at a Conversion
               Price equal to the average of the Closing Bid Prices of the
               Common Stock for the five consecutive trading days preceding
               such Holder's Election Response Notice or such other market
               price that satisfies the applicable exchange or trading market.

          (ii) Mechanics of Fulfilling Holder's Election.  The Company shall
           within one (1) business day  send via facsimile to the Holder of
           this Note, upon receipt of a facsimile copy of a Conversion Notice
           from such Holder that cannot be fully satisfied as described in
           Subsection 3(a), a notice of the Company's inability to fully
           satisfy such Holder's Conversion Notice (the "Inability to Fully
           Convert Notice").  Such Inability to Fully Convert Notice shall
           indicate (i) the reason why the Company is unable to fully satisfy
           such Holder's Conversion Notice, (ii) the Principal Amount of this
           Note plus accrued and unpaid interest thereon that cannot be
           converted and (iii) the applicable Redemption Price.  The Holder
           shall notify the Company of its election pursuant to Subsection
           4(b)(i) above by delivering written notice via facsimile to the
           Company ("Election Response Notice").

          (iii) Holder's Option upon Company Defaults.  If a Registration
           Default (as defined in the Registration Rights Agreement) shall
           have occurred and be continuing, an Event of Default under this
           Note or the Security Agreement shall have occurred and be
           continuing, or the Company shall have defaulted in the payment
           of any Funded Debt (as hereinafter defined) for a period in
           excess of any cure period thereunder (regardless of whether the
           creditor of such Funded Debt shall have declared a default), then
           with respect to all or any part of the unconverted Principal Amount
           of this Note plus accrued and unpaid interest thereon, the Holder,
           solely at such Holder's option, can demand Redemption at the
           Redemption Price; provided, however, that in the event of a
           Redemption after the occurrence of a Registration Default, the
           Company shall be required to redeem not more than the maximum
           amount of accrued interest on the Principal Amount of this plus
           any of such Principal Amount that the Holder could have converted
           into Common Stock due to the restriction imposed by Subsection 3(i);
           and provided, further, that the Holder shall have no right to demand
           Redemption upon the occurrence and continuance of a default in the
           payment of any Funded Debt in the amount of $10,000 or less
           individually or in the aggregate.  A Holder may demand Redemption
           as provided in this Subsection 4(b)(iii) by giving a written notice
           (a "Redemption Notice") by facsimile to the Company at any time
           after the occurrence and during the continuance of a default that
           would permit a Holder to demand Redemption hereunder.  For purposes
           hereof, "Funded Debt" means all (a) indebtedness for borrowed money
           or for the deferred purchase price of property or services (other
           than trade liabilities and accrued expenses incurred in the ordinary
           course of business and payable in accordance with customary
           practices), whether on open account or evidenced by a note, bond,
           debenture or similar instrument or otherwise, (b) obligations under
           capital leases, (c) reimbursement obligations for letters of credit,
           banker's acceptances or other credit accommodations, (d) contingent
           obligations and (e) obligations secured by any lien on the Company's
           property, even if the Company has not assumed such obligations.

          (iv) Payment of Redemption Price.  If the Holder shall elect to
           have this Note redeemed pursuant to Subsection 4(b)(i)(A) or
           Subsection 4(b)(iii), the Company shall pay the Redemption Price
           to such Holder in cash by wire transfer of immediately available
           funds in accordance with such Holder's written wire transfer
           instructions within five (5) days after the Company's receipt of
           the Holder's Election Response Notice or Redemption Notice, as the
           case may be.  If the Company shall fail to pay the applicable
           Redemption Price to such Holder within such five (5) day period
           (other than pursuant to a dispute as to the determination of the
           arithmetic calculation of the Redemption Price), in addition to
           any remedy the Holder of this Note may have hereunder, or under
           the Exchange Agreement, the Registration Rights Agreement, or the
           Security Agreement, such unpaid amount shall bear interest at the
           rate of 3.0% per month (prorated for partial months) until paid in
           full.  Until the  Redemption Price is paid in full to such Holder,
           such Holder may void the  Redemption with respect to the portion of
           the Principal Amount of this Note plus accrued and unpaid interest
           thereon for which the full Redemption Price has not been paid and
           receive back a Note representing such Principal Amount.
           Notwithstanding the foregoing, if the Company fails to pay the
           applicable Redemption Price within such period of five (5) days
           due to a dispute as to the determination of the Redemption Price,
           such dispute shall be resolved pursuant to Section 3(h) with the
           term "Redemption Price" being substituted for the term "Conversion
           Rate".

           (v) Pro-rata Conversion and Redemption.  If the Company or the
           Transfer Agent receives a Conversion Notice or Election Response
           Notice or a Redemption Notice electing  Redemption from more than
           one holder of Convertible Notes on the same day, and the Company
           can convert and/or redeem some, but not all, of such Convertible
           Notes pursuant to this Section 4, the Company shall convert and/or
           redeem from each holder of Convertible Notes electing to have its
           Convertible Notes converted and redeemed at such time an amount
           equal to such holder's pro-rata amount (based on the Principal
           Amount of Convertible Notes held by such holder relative to the
           Principal Amount of all Convertible Notes sought to be converted)
           of all Convertible Notes being converted and redeemed at such time.

    5. Notices.  In case at any time:

       (a) The Company shall declare any dividend upon its Common Stock payable
           in cash or stock or make any other pro rata distribution to the
           holders of its Common Stock; or

       (b) the Company shall offer for subscription pro rata to the holders of
           its Common Stock any additional shares of stock of any class or
           other rights; or

       (c) there shall be any Organic Change;

       then, in any one or more of such cases, the Company shall give, by
       first class mail, postage prepaid, or by facsimile or by recognized
       overnight delivery service to non-U.S. residents, addressed to the
       Holder of this Note at the address of such Holder as shown on the
       books of the Company, (i) at least twenty (20) Trading Days' prior
       written notice of the date on which the books of the Company shall
       close or a record shall be taken for such dividend, distribution or
       subscription rights or for determining rights to vote in respect of
       any such Organic Change and (ii) in the case of any such Organic Change,
       at least twenty (20) Trading Days' prior written notice of the date
       when the same shall take place.  Such notice in accordance with the
       foregoing clause (i) shall also specify, in the case of any such
       dividend, distribution or subscription rights, the date on which the
       holders of Common Stock shall be entitled thereto, and such notice in
       accordance with clause (ii) shall also specify the date on which the
       holders of Common Stock shall be entitled to exchange their Common Stock
       for securities or other property deliverable upon such Organic Change.

    6. Stock to be Reserved.  The Company has a sufficient number of shares of
       Common Stock available to reserve for issuance upon the conversion of all
       outstanding Convertible Notes, assuming immediate conversion. The Company
       will at all times reserve and keep available out of its authorized Common
       Stock, solely for the purpose of issuance upon the conversion of all of
       its Convertible Notes as herein provided, such number of shares of Common
       Stock as shall then be issuable upon the conversion of all Notes.  The
       Company covenants that all shares of Common Stock that  shall be so
       issued shall be duly and validly issued, fully paid and non-assessable.
       The Company will take all such action as may be so taken without
       violation of any applicable law or regulation to have a sufficient
       number of authorized but unissued shares of Common Stock to issue upon
       conversion of all Convertible Notes.  The Company will not take any
       action that results in any adjustment of the conversion rights if the
       total number of shares of Common Stock issued and issuable after such
       action upon conversion of the this Note would exceed the total number
       of shares of Common Stock then authorized by the Company's Certificate
       of Incorporation.

    7. Default and Remedies.

       (a) Event of Default.  Each of the following shall constitute an
       "Event of Default":

           (i) the Company shall default (A) in the payment of the installment
           of principal and interest due on September 7, 2001, or (B) in the
           payment of any other installment of principal or interest due on
           this Note and the default in the payment of such other installment
           shall continue for a period of thirty (30) days; or

           (ii) any of the representations or warranties made by the Company
           herein, in the Exchange Agreement, the Registration Rights
           Agreement, the Security Agreement or in any agreement, certificate
           or financial or other written statements heretofore or hereafter
           furnished by the Company in connection with the execution and
           delivery of this Note or the Exchange Agreement shall be false or
           misleading in any material respect at the time made; or

           (iii) a default or an event of default shall have occurred and be
           continuing with respect to any Funded Debt in excess of $10,000 in
           the aggregate; or

           (iv) the Company shall (A) admit in writing its inability to pay
           its debts generally as they mature; (B) make an assignment for the
           benefit of creditors or commence proceedings for its dissolution;
           or (C) apply for or consent to the appointment of a trustee,

           without its consent and shall not be discharged within sixty (60)
           days after such appointment; or

           (vi) any governmental agency or any court of competent jurisdiction
           at the instance of any governmental agency shall assume custody or
           control of the whole or any substantial portion of the properties
           or assets of the Company and shall not be dismissed within sixty
           (60) days thereafter; or

           (vii) any money judgment, writ or warrant of attachment, or similar
           process in excess of One Hundred Thousand ($100,000) Dollars in
           the aggregate shall be entered or filed against the Company or any
           of its properties or other assets and shall remain unpaid,
           unvacated, unbonded or unstayed for a period of sixty (60) days
           or in any event later than five (5) days prior to the date of any
           proposed sale thereunder; or

           (viii) bankruptcy, reorganization, insolvency or liquidation
           proceedings or other proceedings for relief under any bankruptcy
           law or any law for the relief of debtors shall be instituted by or
           against the Company and, if instituted against the Company, shall
           not be dismissed within sixty (60) days after such institution or
           the Company shall by any action or answer approve of, consent to,
           or acquiesce in any such proceedings or admit the material
           allegations of, or default in answering a petition filed in any
           such proceeding; or

           (ix) termination of Monte Ross as Chairman of the Company (including
           a change or diminution of his duties as such), whether by
           resignation, termination, death, disability or otherwise, unless
           the Holder shall have consented to such termination, except for a
           termination in connection with a "Change of Control" (as defined on
           Exhibit B hereto) of the Company; or

           (x) the occurrence of any event that would result in a Material
           Adverse Effect with respect to the Company; or

           (xi) the Company's Common Stock ceases to be traded in the United
           States over-the-counter market or on a national securities exchange
           in the United States; or

           (xii) the Common Stock ceases to be registered under the Exchange
           Act.

       (b) Remedies.  Upon the occurrence and during the continuance of any
           Event of Default, subject to the prior rights of the Senior Debt
           (as defined in Section 16), the Holder may declare this Note
           immediately due and payable, without presentment, demand, protest
           or notice of any kind, all of which are hereby expressly waived,
           anything herein or in any note or other instruments contained to
           the contrary notwithstanding, and the Holder may immediately enforce
           any and all of the Holder's rights and remedies provided herein or
           in the Security Agreement or any other rights or remedies afforded
           by law.  Such payment shall be made within three (3) Trading Days
           of such demand, and if not paid within such period, the Company
           shall pay the holder liquidated damages of three percent (3%) per
           month of such amount until paid, pro-rated for any partial months.
           The Holder's rights under this Subsection 7(b) shall be in addition
           to, and not in lieu of, the Holder's right to demand Redemption
           pursuant to Section 4 hereof or to exercise any other rights or
           remedies as contemplated by Section 15 hereof.

    8. Payment Obligation Unconditional.  No provision of this Note shall alter
       or impair the obligation of the Company, which is absolute and
       unconditional, to pay the principal of, and interest on, this Note at
       the time, place, and rate, and in the coin or currency or shares of
       Common Stock, herein prescribed.  This Note is a direct obligation of
       the Company.

    9. No Recourse to Stockholders, etc.  No recourse shall be had for the
       payment of the principal of, or the interest on, this Note, or for any
       claim based hereon, or otherwise in respect hereof, against any
       incorporator, shareholder, employee, officer or director, as such,
       past, present or future, of the Company or any successor corporation,
       whether by virtue of any constitution, statute or rule of law, or by
       the enforcement of any assessment or penalty or otherwise, all such
       liability being, by the acceptance hereof and as part of the
       consideration for the issue hereof, expressly waived and released.

   10. No Rights as Stockholder.  No provision of this Note shall be construed
       as conferring upon the Holder the right to vote or to receive dividends
       or to consent or receive notice as a stockholder in respect of any
       meeting of stockholders or any rights whatsoever as a stockholder of
       the Company, unless and to the extent converted in accordance with
       the terms hereof.

   11. Definition of Common Stock.  As used in this Note, the term "Common
       Stock" shall mean and include the Company's authorized Common Stock,
       $0.01 par value, as constituted on the Issuance Date of this Note,
       and shall also include any capital stock of any class of the Company
       thereafter authorized which shall neither be limited to a fixed sum or
       percentage of par value in respect of the rights of the holders thereof
       to participate in dividends nor entitled to a preference in the
       distribution of assets upon the voluntary or involuntary liquidation,
       dissolution or winding up of the Company; provided that the shares of
       Common Stock receivable upon conversion of this Note shall include
       only shares designated as Common Stock of the Company on the Issuance
       Date of this Note, or in case of any reorganization, reclassification,
       or stock split of the outstanding shares thereof, the stock,
       securities or assets provided for in Sections 3(f) and (g).

   12. Loss, Theft, Destruction of Note.  Upon receipt of evidence satisfactory
       to the Company of the loss, theft, destruction or mutilation of this
       Note and, in the case of any such loss, theft or destruction, upon
       receipt of indemnity reasonably satisfactory to the Company (which
       shall not include the posting of any bond), or, in the case of any
       such mutilation, upon surrender and cancellation of this Note, the
       Company shall make, issue and deliver, in lieu of such lost, stolen,
       destroyed or mutilated Note, one or more new Notes of like tenor.
       This Note shall be held and owned upon the express condition that the
       provisions of this Section 12 are exclusive with respect to the
       replacement of mutilated, destroyed, lost or stolen Notes and shall
       preclude any and all other rights and remedies notwithstanding any law
       or statue existing or hereafter enacted to the contrary with respect
       to the replacement of negotiable instruments or other securities without
       the surrender thereof.

   13. Record Owner.  The Company may deem the person in whose name this Note
       shall be registered upon the registry books of the Company to be, and
       may treat it as, the absolute owner of this Note for the purpose of
       conversion of this Note and for all other purposes, and the Company
       shall not be affected by any notice to the contrary.  All such payments
       and such conversion shall be valid and effective to satisfy and
       discharge the liability upon this Note to the extent of the sum or
       sums so paid or the conversion so made.

   14. Register.  The Company shall maintain a transfer agent, which may be
       the transfer agent for the Common Stock or the Company itself, for the
       registration of the Convertible Notes.  Upon any transfer of this Note
       in accordance with the provisions hereof, the Company shall register
       or cause the transfer agent to register such transfer on the Note
       Register.

   15. Remedies, Characterizations, Other Obligations, Breaches and Injunctive
       Relief.  The remedies provided in this Note shall be cumulative and in
       addition to all other remedies available under this Note, at law or in
       equity (including a decree of specific performance and/or other
       injunctive relief).  No remedy contained herein shall be deemed a
       waiver of compliance with the provisions giving rise to such remedy
       and nothing herein shall limit a holder's right to pursue actual
       damages for any failure by the Company to comply with the terms of
       this Note.  Amounts set forth or provided for herein with respect to
       payments, conversion and the like (and the computation thereof) shall
       be the amounts to be received by the Holder hereof and shall not,
       except as expressly provided herein, be subject to any other obligation
       of the Company (or the performance thereof).  The Company acknowledges
       that a breach by it of its obligations hereunder will cause irreparable
       harm to the Holders of this Note and that the remedy at law for any
       such breach may be inadequate.  The Company therefore agrees that, in
       the event of any such breach or threatened breach, the Holders of this
       Note shall be entitled, in addition to all other available remedies,
       to an injunction restraining any breach, without the necessity of
       showing economic loss and without any bond or other security being
       required.

   16. Subordination to Senior Debt.  The obligations of the Company under
       this Note are secured by a security interest in substantially all of
       the Company's assets, as set forth in a Security Agreement of even date
       herewith from the Company to the initial holders of the Convertible
       Notes.  The Company has represented to the Holders that, except as
       disclosed on Schedule C to the Security Agreement and except for other
       Permitted Liens under the Security Agreement, the Company's assets are
       not subject to any liens.  In the event of any distribution, division
       or application, partial or complete, voluntary or involuntary, by
       operation of law or otherwise, of all or any part of the assets of
       the Company, or the proceeds thereof, to creditors of the Company or
       upon any indebtedness of the Company, by reason of the liquidation,
       dissolution or other winding-up of the Company, or the Company's
       business or affairs, or in the event of any sale, receivership,
       insolvency or bankruptcy proceeding, assignment for the benefit of
       creditors or any other proceeding by or against the Company for any
       relief under any bankruptcy or insolvency law or laws relating to the
       relief of debtors, readjustment of indebtedness, reorganizations,
       compositions or extensions, then, and in each such event, each payment
       or distribution of any kind or character, either in cash, securities
       or other property, which shall be payable or deliverable upon or with
       respect to any of the obligations of the Company evidenced by this
       Note shall be paid, prior to any payment to the Holder, directly to
       the holders of the Senior Debt, for application on account of the
       Senior Debt until the Senior Debt is paid in full.  In addition, upon
       a written request from the Company, the Holder shall agree to
       subordinate its rights under the Security Agreement and to payment
       of the Convertible Notes to a holder of Senior Debt (as hereinafter
       defined) in accordance with the terms of a subordination agreement
       having customary terms and being reasonably acceptable to the
       Holders.  The Company acknowledges that the terms of such subordination
       agreement will not be reasonably acceptable to the Holders unless,
       among other things, (i) the Company will be required to pay installments
       of principal and interest due under the Convertible Notes so long as
       there is no default under the Senior Debt, (ii) upon the occurrence and
       during the continuance of an Event of Default hereunder, the Holder
       shall have the right, after 30 days from the occurrence of each such
       Event of Default, to accelerate payment of this Note and to declare
       that this Note is forthwith due and payable and to sue for payment of
       the Note or join with any other creditor of the Company other than
       holders of the Senior Debt or their agents to sue for such payment and
       to exercise any rights it may have under the Security Agreement,
       (iii) the proposed terms of such subordination agreement do not limit
       or restrict the rights of the Holder under this Note or the Security
       Agreement, other than to subordinate the right of payment hereunder
       and thereunder to the holder of the Senior Debt, and (iv) in the case
       of any proposed subordination agreement that is intended to be a
       substitute for an existing subordination agreement, the proposed
       subordination agreement does not expand the rights of the holder of
       the Senior Debt with respect to collection of the Senior Debt.
       "Senior Debt" shall mean all future obligations of the Company to a
       licensed commercial lender in connection with a revolving credit
       and/or term loan facility extended or to be extended by such licensed
       commercial lender to the Company, the amount of loans under such
       facility being determined by reference to the value of the Company's
       accounts receivable, inventory and work in process and secured by the
       Company's accounts receivable and/or inventory, and shall include the
       outstanding principal amount of such Senior Debt from time to time,
       whenever incurred.  Anything herein to the contrary notwithstanding,
       Senior Debt shall not include any indebtedness or other obligations
       of the Company directly or indirectly convertible into or exchangeable
       for equity securities of the Company.

   17. Construction.  This Note shall be deemed to be jointly drafted by the
       Company and the initial holders of the Convertible Notes and shall
       not be construed against any person as the drafter hereof.

   18. Failure or Indulgence Not Waiver.  No failure or delay on the part of
       the Holder of this Note in the exercise of any power, right or
       privilege hereunder shall operate as a waiver thereof (except to the
       extent that such power, right or privilege must, in accordance with
       the terms of this Note, be exercised within a specified period of time
       and such period of time has lapsed without such power, right or
       privilege being exercised), nor shall any single or partial exercise
       of any such power, right or privilege preclude other or further
       exercise thereof or of any other right, power or privilege.

   19. Governing Law.  This Note shall be governed by and construed in
       accordance with the laws of the State of New York.  Each of the
       parties consents to the jurisdiction of the federal courts whose
       districts encompass any part of the City of New York or the state
       courts of the State of New York sitting in the City of New York in
       connection with any dispute arising under this Agreement and hereby
       waives, to the maximum extent permitted by law, any objection,
       including any objection based on forum non conveniens, to the bringing
       of any such proceeding in such jurisdictions.

DEFINITION OF CHANGE OF CONTROL

For purposes of this Agreement, "Change of Control" means:

 (a) The acquisition by any individual, entity, or group (within the
 meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of
 1934, as amended (the "Exchange Act")) of beneficial ownership (within the
 meaning of Rule 13d-3 promulgated under the Exchange Act) of 50% or more of
 either (1) the then outstanding shares of common stock of the Company (the
 "Outstanding Company Common Stock") or (2) the combined voting power of the
 then outstanding voting securities of the Company entitled to vote generally
 in the election of directors (the "Outstanding Company Voting Securities");
 provided, however, that for purposes of this clause (A), the following
 acquisitions of stock shall not result in a Change of Control:  (1) any
 acquisition directly from the Company, (2) any acquisition by the Company,
 (3) any acquisition by any employee benefit plan (or related trust)
 sponsored or maintained by the Company or any corporation controlled by the
 Company, or (4) any acquisition by any corporation pursuant to a transaction
 that complies with clauses (1), (2), and (3) of subsection (c) of this
 definition; or

 (b) Consummation of a reorganization, merger, or consolidation or sale or
 other disposition of all or substantially all of the assets of the Company
 (a "Business Combination"), in each case, unless following such Business
 Combination, (1) all or substantially all of the individuals and entities
 who were the beneficial owners, respectively, of the Outstanding Company
 Common Stock and Outstanding Company Voting Securities immediately prior
 to such Business Combination beneficially own, directly or indirectly, more
 than 50% of, respectively, the outstanding shares of common stock and the
 combined voting power of the then outstanding voting securities entitled to
 vote generally in the election of directors, as the case may be, of the
 corporation resulting from such Business Combination, including, without
 limitation, a corporation that as a result of such transaction owns the
 Company or all or substantially all of the Company's assets either directly
 or through one or more subsidiaries (any such corporation being referred
 to herein as a "Resulting Corporation"), in substantially the same proportions
 as their ownership of the Outstanding Company Common Stock and Outstanding
 Company Voting Securities, as the case may be, immediately prior to such
 Business Combination, (2) no Person (excluding any employee benefit plan
 (or related trust) of the Company or a Resulting Corporation) beneficially
 owns, directly or indirectly, 50% or more of, respectively, the outstanding
 shares of common stock of the Resulting Corporation or the combined voting
 power of the then outstanding voting securities of such Resulting Corporation
 except to the extent that such ownership existed prior to the Business
 Combination, and (3) at least a majority of the members of the board of
 directors of the Resulting Corporation were members of the Incumbent Board
 at the time of the execution of the initial agreement, or of the action of
 the Board, providing for such Business Combination.

the Company (the "Common Stock").  The purchase price of one share of Common
Stock (the "Exercise Price") under this Warrant shall be $1.50.  The Exercise
Price and the number of shares for which the Warrant is exercisable shall be
subject to adjustment as provided herein. In the event of any conflict between
the terms of this Warrant and the Exchange Agreement, dated as of August ____,
2001, between the Company and, among others, the initial Holder of this
Warrant (the "Exchange Agreement"), the Exchange Agreement shall control.
Capitalized terms used and not otherwise defined herein shall have the
meanings set forth for such terms in the Exchange Agreement.

    1. Title to Warrant.  Prior to the Termination Date and subject to
    compliance with applicable laws, this Warrant and all rights hereunder
    are transferable, in whole or in part, at the office or agency of the
    Company by the Holder hereof in person or by duly authorized attorney,
    upon surrender of this Warrant together with the Assignment Form annexed
    hereto properly endorsed.

    2. Authorization of Shares.  The Company covenants that all shares of
    Common Stock which may be issued upon the exercise of rights represented
    by this Warrant will, upon exercise of the rights represented by this
    Warrant, be duly authorized, validly issued, fully paid and nonassessable
    and free from all taxes, liens and charges in respect of the issue thereof
    (other than taxes in respect of any transfer occurring contemporaneously
    with such issue).

    3. Exercise of Warrant.

       (a) Except as provided in Section 3(b) or Section 4 herein, exercise of
       the purchase rights represented by this Warrant may be made at any time
       or times on or after the Initial Exercise Date, and before the close of
       business on the Termination Date by the surrender of this Warrant and
       the Notice of Exercise Form annexed hereto duly executed, at the office
       of the Company (or such other office or agency of the Company as it may
       designate by notice in writing to the registered Holder hereof at the
       address of such Holder appearing on the books of the Company) and upon
       payment of the Exercise Price of the shares thereby purchased by wire
       transfer or cashier's check drawn on a United States bank, the Holder
       of this Warrant shall be entitled to receive a certificate for the
       number of shares of Common Stock so purchased.   This Warrant shall be
       deemed to have been exercised and such certificate or certificates shall
       be deemed to have been issued, and Holder or any other person so
       designated to be named therein shall be deemed to have become a holder
       of record of such shares for all purposes, as of the date the Warrant
       has been exercised by payment to the Company of the Exercise Price and
       all taxes required to be paid by Holder, if any, pursuant to Section 5
       prior to the issuance of such shares, have been paid.  If this Warrant
       shall have been exercised in part, the Company shall, at the time of
       delivery of the certificate or certificates representing Warrant Shares,
       deliver to Holder a new Warrant evidencing the rights of Holder to
       purchase the unpurchased shares of Common Stock called for by this
       Warrant, which new Warrant shall in all other respects be identical with
       this Warrant.

       (b) Anything in Section 3(a) to the contrary notwithstanding, in no
       event shall Holder be entitled to exercise this Warrant if, upon giving
       effect to such exercise, the Holder and its "affiliates" (as defined in
       Rule 405 under the 1933 Act) would  beneficially own an aggregate number
       of shares of Common Stock that would exceed 9.99% of the outstanding
       shares of the Common Stock following such exercise.  For purposes of
       this Section, the aggregate number of shares of Common Stock
       beneficially owned by the Holder and its affiliates shall include the
       number of shares of Common Stock issuable upon exercise of the Warrants
       with respect to which the determination is being made, but shall
       exclude the number of shares of Common Stock which would be issuable
       upon (i) conversion of any nonconverted Convertible Notes beneficially
       owned by the Holder and its affiliates and (ii) exercise or conversion
       of the unexercised or unconverted portion of any other securities of
       the Company (including, without limitation, any other Warrants or
       convertible preferred stock) subject to a limitation on conversion or
       exercise analogous to the limitation contained herein beneficially
       owned by the Holder and its affiliates.  Except as set forth in the
       preceding sentence, for purposes of this Section 3(b), beneficial
       ownership shall be calculated in accordance with Section 13(d) of the
       1934 Act.  For purposes of this Section, in determining the number of
       outstanding shares Common Stock the Holder may rely on the number of
       outstanding shares of Common Stock as reflected in (1) the Company's
       most recent Form 10-QSB or Form 10-KSB, as the case may be, (2) a more
       recent public announcement by the Company or (3) any other notice by
       the Company or its transfer agent setting forth the number of shares
       of Common Stock outstanding.  For any reason at any time, upon the
       written or oral request of the Holder, the Company shall immediately
       confirm orally and in writing to the Holder the number of shares of
       Common Stock then outstanding.  In any case, the number of outstanding
       shares of Common Stock shall be determined  after giving effect to
       conversions of Convertible Notes by the Holder since the date as of
       which such number of outstanding shares of Common Stock was reported.
       To the extent that the limitation contained in this Section 3(b)
       applies, the determination of whether this Warrant is exercisable
       (in relation to other securities owned by the Holder) and of which
       portion of the Principal Amount of Convertible Notes is convertible
       shall be in the sole discretion of the Holder, and the exercise of
       this Warrant shall be deemed to be the Holder's determination of
       whether this Warrant is exercisable (in relation to other securities
       owned by the Holder) and of which portion of the Principal Amount of
       Convertible Notes is convertible, in each case subject to such
       aggregate percentage limitation, and the Company shall have no
       obligation or right to verify or confirm the accuracy of such
       determination. Nothing contained herein shall be deemed to restrict
       the right of the Holder to exercise this Warrant at such time as such
       exercise will not violate the provisions of this Section.  This Holder
       may waive the provisions of this Section 3(b) as to itself (and solely
       as to itself) upon not less than 75 days' prior notice to the Company,
       and the provisions of this Section 3(b) shall continue to apply until
       such 75th day (or such later date as may be specified in such notice
       of waiver). No exercise in violation of this Section, but otherwise in
       accordance with this Warrant, shall affect the status of the Common
       Stock issued upon such exercise as validly issued, fully-paid and
       nonassessable.

    4. No Fractional Shares or Scrip.  No fractional shares or scrip
    representing fractional shares shall be issued upon the exercise of this
    Warrant.  As to any fraction of a share which Holder would otherwise be
    entitled to purchase upon such exercise, the Company shall pay a cash
    adjustment in respect of such final fraction in an amount equal to the
    Exercise Price.

    5. Charges, Taxes and Expenses.  Issuance of certificates for shares of
    Common Stock upon the exercise of this Warrant shall be made without
    charge to the Holder hereof for any issue or transfer tax or other
    incidental expense in respect of the issuance of such certificate, all of
    which taxes and expenses shall be paid by the Company, and such
    certificates shall be issued in the name of the Holder of this Warrant or
    in such name or names as may be directed by the Holder of this Warrant;
    provided, however, that in the event certificates for shares of Common
    Stock are to be issued in a name other than the name of the Holder of
    this Warrant, this Warrant when surrendered for exercise shall be
    accompanied by the Assignment Form attached hereto duly executed by the
    Holder hereof; and the Company may require, as a condition thereto, the
    payment of a sum sufficient to reimburse it for any transfer tax incidental
    thereto.

    6. Closing of Books.  The Company will not close its shareholder books or
    records in any manner which prevents the timely exercise of this Warrant.

    7. Transfer, Division and Combination.

       (a) Subject to compliance with any applicable securities laws, transfer
       of this Warrant and all rights hereunder, in whole or in part, shall be
       registered on the books of the Company to be maintained for such
       purpose, upon surrender of this Warrant at the principal office of the
       Company, together with a written assignment of this Warrant substantially
       in the form attached hereto duly executed by Holder or its agent or
       attorney and funds sufficient to pay any transfer taxes payable upon the
       making of such transfer.  Upon such surrender and, if required, such
       payment, the Company shall execute and deliver a new Warrant or
       Warrants in the name of the assignee or assignees and in the denomination
       or denominations specified in such instrument of assignment, and shall
       issue to the assignor a new Warrant evidencing the portion of this
       Warrant not so assigned, and this Warrant shall promptly be cancelled.
       A Warrant, if properly assigned, may be exercised by a new Holder for
       the purchase of shares of Common Stock without having a new Warrant
       issued.

       (b) This Warrant may be divided or combined with other Warrants upon
       presentation hereof at the aforesaid office of the Company, together
       with a written notice specifying the names and denominations in which
       new Warrants are to be issued, signed by Holder or its agent or
       attorney.  Subject to compliance with Section 7(a), as to any transfer
       which may be involved in such division or combination, the Company
       shall execute and deliver a new Warrant or Warrants in exchange for
       the Warrant or Warrants to be divided or combined in accordance with
       such notice.

       (c) The Company shall prepare, issue and deliver at its own expense
       (other than transfer taxes) the new Warrant or Warrants under this
       Section 7.

       (d) The Company agrees to maintain, at its aforesaid office, books for
       the registration and the registration of transfer of the Warrants.

    8. No Rights as Shareholder until Exercise.  This Warrant does not entitle
    the Holder hereof to any voting rights or other rights as a shareholder of
    the Company prior to the exercise hereof.  Upon the surrender of this
    Warrant and the payment of the aggregate Exercise Price, the Warrant Shares
    so purchased shall be and be deemed to be issued to such Holder as the
    record owner of such shares as of the close of business on the later of
    the date of such surrender or payment.

    9. Loss, Theft, Destruction or Mutilation of Warrant.  The Company
    covenants that upon receipt by the Company of evidence reasonably
    satisfactory to it of the loss, theft, destruction or mutilation of this
    Warrant certificate or any stock certificate relating to the Warrant
    Shares, and in case of loss, theft or destruction, of indemnity or security
    reasonably satisfactory to it (which shall not include the posting of any
    bond), and upon surrender and cancellation of such Warrant or stock
    certificate, if mutilated, the Company will make and deliver a new Warrant
    or stock certificate of like tenor and dated as of such cancellation, in
    lieu of such Warrant or stock certificate.

   10. Saturdays, Sundays, Holidays, etc.  If the last or appointed day for
    the taking of any action or the expiration of any right required or granted
    herein shall be a Saturday, Sunday or a legal holiday, then such action may
    be taken or such right may be exercised on the next succeeding day not a
    Saturday, Sunday or legal holiday.

   11. Adjustments of Exercise Price and Number of Warrant Shares.

       (a) Stock Splits, etc. The number and kind of securities purchasable
       upon the exercise of this Warrant and the Exercise Price shall be
       subject to adjustment from time to time upon the happening of any of
       the following.  In case the Company shall (i) pay a dividend in shares
       of Common Stock or make a distribution in shares of Common Stock to
       holders of its outstanding Common Stock, (ii) subdivide its outstanding
       shares of Common Stock into a greater number of shares of Common Stock,
       (iii) combine its outstanding shares of Common Stock into a smaller
       number of shares of Common Stock or (iv) issue any shares of its capital
       stock in a reclassification of the Common Stock, then the number of
       Warrant Shares purchasable upon exercise of this Warrant immediately
       prior thereto shall be adjusted so that the Holder of this Warrant shall
       be entitled to receive the kind and number of Warrant Shares or other
       securities of the Company which he would have owned or have been
       entitled to receive had such Warrant been exercised in advance thereof.
       Upon each such adjustment of the kind and number of Warrant Shares or
       other securities of the Company which are purchasable hereunder, the
       Holder of this Warrant shall thereafter be entitled to purchase the
       number of Warrant Shares or other securities resulting from such
       adjustment at an Exercise Price per Warrant Share or other security
       obtained by multiplying the Exercise Price in effect immediately prior
       to such adjustment by the number of Warrant Shares purchasable pursuant
       hereto immediately prior to such adjustment and dividing by the number
       of Warrant Shares or other securities of the Company resulting from such
       adjustment.  An adjustment made pursuant to this paragraph shall become
       effective immediately after the effective date of such event retroactive
       to the record date, if any, for such event.

       (b) Reorganization, Reclassification, Merger, Consolidation or
       Disposition of Assets.  In case the Company shall reorganize its
       capital, reclassify its capital stock, consolidate or merge with or
       into another corporation (where the Company is not the surviving
       corporation or where there is a change in or distribution with respect
       to the Common Stock of the Company), or sell, transfer or otherwise
       dispose of all or substantially all its property, assets or business to
       another corporation and, pursuant to the terms of such reorganization,
       reclassification, merger, consolidation or disposition of assets, shares
       of common stock of the successor or acquiring corporation, or any cash,
       shares of stock or other securities or property of any nature whatsoever
       (including warrants or other subscription or purchase rights) in
       addition to or in lieu of common stock of the successor or acquiring
       corporation ("Other Property"), are to be received by or distributed
       to the holders of Common Stock of the Company, then Holder shall have
       the right thereafter to receive, upon exercise of this Warrant, the
       number of shares of common stock of the successor or acquiring
       corporation or of the Company, if it is the surviving corporation,
       and Other Property receivable upon or as a result of such
       reorganization, reclassification, merger, consolidation or disposition
       of assets by a holder of the number of shares of Common Stock for
       which this Warrant is exercisable immediately prior to such event.
       In case of any such reorganization, reclassification, merger,
       consolidation or disposition of assets, the successor or acquiring
       corporation (if other than the Company) shall expressly assume the
       due and punctual observance and performance of each and every covenant
       and condition of this Warrant to be performed and observed by the
       Company and all the obligations and liabilities hereunder, subject to
       such modifications as may be deemed appropriate (as determined in good
       faith by resolution of the Board of Directors of the Company) in order
       to provide for adjustments of shares of Common Stock for which this
       Warrant is exercisable which shall be as nearly equivalent as
       practicable to the adjustments provided for in this Section 11.  For
       purposes of this Section 11, "common stock of the successor or acquiring
       corporation" shall include stock of such corporation of any class
       which is not preferred as to dividends or assets over any other class
       of stock of such corporation and which is not subject to redemption
       and shall also include any evidences of indebtedness, shares of stock
       or other securities which are convertible into or exchangeable for any
       such stock, either immediately or upon the arrival of a specified date
       or the happening of a specified event and any warrants or other rights
       to subscribe for or purchase any such stock.  The foregoing provisions
       of this Section 11 shall similarly apply to successive reorganizations,
       reclassifications, mergers, consolidations or disposition of assets.

   12. Voluntary Adjustment by the Company.  The Company may at any time during
       the term of this Warrant, reduce the then current Exercise Price to
       any amount and for any period of time deemed appropriate by the Board
       of Directors of the Company.

   13. Notice of Adjustment.  Whenever the number of Warrant Shares or number
       or kind of securities or other property purchasable upon the exercise
       of this Warrant or the Exercise Price is adjusted, as herein provided,
       the Company shall promptly mail by registered or certified mail,
       return receipt requested, to the Holder of this Warrant notice of such
       adjustment or adjustments setting forth the number of Warrant Shares
       (and other securities or property) purchasable upon the exercise of
       this Warrant and the Exercise Price of such Warrant Shares (and other
       securities or property) after such adjustment, setting forth a brief
       statement of the facts requiring such adjustment and setting forth the
       computation by which such adjustment was made.  Such notice, in the
       absence of manifest error, shall be conclusive evidence of the
       correctness of such adjustment.

   14. Notice of Corporate Action.  If at any time:

       (i) the Company shall take a record of the holders of its Common Stock
       for the purpose of entitling them to receive a dividend or other
       distribution, or any right to subscribe for or purchase any evidences
       of its indebtedness, any shares of stock of any class or any other
       securities or property, or to receive any other right, or

       (ii) there shall be any capital reorganization of the Company, any
       reclassification or recapitalization of the capital stock of the
       Company or any consolidation or merger of the Company with, or any
       sale, transfer or other disposition of all or substantially all the
       property, assets or business of the Company to, another corporation
       or,

       (iii) there shall be a voluntary or involuntary dissolution, liquidation
       or winding up of the Company;

       then, in any one or more of such cases, the Company shall give to
       Holder (i) at least 20 days' prior written notice of the record date
       for such dividend, distribution or right or for determining rights to
       vote in respect of any such reorganization, reclassification, merger,
       consolidation, sale, transfer, disposition, liquidation or winding up,
       and (ii) in the case of any such reorganization, reclassification,
       merger, consolidation, sale, transfer, disposition, dissolution,
       liquidation or winding up, at least 20 days' prior written notice of
       the date when the same shall take place.  Such notice in accordance
       with the foregoing clause also shall specify (i) the date on which
       any such record is to be taken for the purpose of such dividend,
       distribution or right, the date on which the holders of Common Stock
       shall be entitled to any such dividend, distribution or right, and
       the amount and character thereof, and (ii) the date on which any such
       reorganization, reclassification, merger, consolidation, sale, transfer,
       disposition, dissolution, liquidation or winding up is to take place
       and the time, if any such time is to be fixed, as of which the holders
       of Common Stock shall be entitled to exchange their shares of Common
       Stock for securities or other property deliverable upon such disposition,
       dissolution, liquidation or winding up.  Each such written notice shall
       be sufficiently given if addressed to Holder at the last address of
       Holder appearing on the books of the Company and delivered in
       accordance with Section 16(d).

   15. Authorized Shares.

       (a) The Company covenants that during the period the Warrant is
       outstanding, it will reserve from its authorized and unissued Common
       Stock a sufficient number of shares to provide for the issuance of the
       Warrant Shares upon the exercise of any purchase rights under this
       Warrant.  The Company further covenants that its issuance of this
       Warrant shall constitute full authority to its officers who are
       charged with the duty of executing stock certificates to execute and
       issue the necessary certificates for the Warrant Shares upon the
       exercise of the purchase rights under this Warrant.  The Company will
       take all such reasonable action as may be necessary to assure that
       such Warrant Shares may be issued as provided herein without violation
       of any applicable law or regulation, or of any requirements of the
       Principal Market upon which the Common Stock may be listed.

       (b) The Company shall not by any action, including, without limitation,
       amending its certificate of incorporation or through any
       reorganization, transfer of assets, consolidation, merger,
       dissolution, issue or sale of securities or any other voluntary
       action, avoid or seek to avoid the observance or performance of any
       of the terms of this Warrant, but will at all times in good faith
       assist in the carrying out of all such terms and in the taking of all
       such actions as may be necessary or appropriate to protect the rights
       of Holder against impairment.  Without limiting the generality of the
       foregoing, the Company will (i) not increase the par value of any
       shares of Common Stock receivable upon the exercise of this Warrant
       above the amount payable therefor upon such exercise immediately prior
       to such increase in par value, (ii) take all such action as may be
       necessary or appropriate in order that the Company may validly and
       legally issue fully paid and nonassessable shares of Common Stock upon
       the exercise of this Warrant, and (iii) use its best efforts to obtain
       all such authorizations, exemptions or consents from any public
       regulatory body having jurisdiction thereof as may be necessary to
       enable the Company to perform its obligations under this Warrant.

       (c) Upon the request of Holder, the Company will at any time during
       the period this Warrant is outstanding acknowledge in writing, in form
       reasonably satisfactory to Holder, the continuing validity of this
       Warrant and the obligations of the Company hereunder.

       (d) Before taking any action which would cause an adjustment reducing
       the current Exercise Price below the then par value, if any, of the
       shares of Common Stock issuable upon exercise of the Warrants, the
       Company shall take any corporate action which may be necessary in
       order that the Company may validly and legally issue fully paid and
       non-assessable shares of such Common Stock at such adjusted Exercise
       Price.

       (e) Before taking any action which would result in an adjustment in
       the number of shares of Common Stock for which this Warrant is
       exercisable or in the Exercise Price, the Company shall obtain all
       such authorizations or exemptions thereof, or consents thereto, as
       may be necessary from any public regulatory body or bodies having
       jurisdiction thereof.

   16. Miscellaneous.

       (a) Jurisdiction. This Warrant shall be binding upon any successors or
       assigns of the Company.  This Warrant shall constitute a contract under
       the laws of New York  without regard to its conflict of law, principles
       or rules, and be subject to arbitration pursuant to the terms set
       forth in the Exchange Agreement.

       (b) Restrictions.  The Holder hereof acknowledges that the Warrant
       Shares acquired upon the exercise of this Warrant, if not registered,
       will have restrictions upon resale imposed by state and federal
       securities laws.

       (c) Nonwaiver and Expenses.  No course of dealing or any delay or
       failure to exercise any right hereunder on the part of Holder shall
       operate as a waiver of such right or otherwise prejudice Holder's
       rights, powers or remedies, notwithstanding all rights hereunder
       terminate on the Termination Date.  If the Company fails to comply
       with any  provision of this Warrant, the Company shall pay to Holder
       such amounts as shall be sufficient to cover any costs and expenses
       including, but not limited to, reasonable attorneys' fees, including
       those of appellate proceedings, incurred by Holder in collecting any
       amounts due pursuant hereto or in otherwise enforcing any of its
       rights, powers or remedies hereunder, unless the Company prevails in
       such litigation in which event it will be entitled its reasonable
       attorneys' fees and expenses.

       (d) Notices.  Any notice, request or other document required or
       permitted to be given or delivered to the Holder hereof by the Company
       shall be delivered in accordance with the notice provisions of the
       Exchange Agreement.

       (e) Limitation of Liability.  No provision hereof, in the absence of
       affirmative action by Holder to purchase shares of Common Stock, and
       no enumeration herein of the rights or privileges of Holder hereof,
       shall give rise to any liability of Holder for the purchase price of
       any Common Stock or as a stockholder of the Company, whether such
       liability is asserted by the Company or by creditors of the Company.

       (f) Remedies.  Holder, in addition to being entitled to exercise all
       rights granted by law, including recovery of damages, will be entitled
       to specific performance of its rights under this Warrant.  The Company
       agrees that monetary damages would not be adequate compensation for
       any loss incurred by reason of a breach by it of the provisions of
       this Warrant and hereby agrees to waive the defense in any action for
       specific performance that a remedy at law would be adequate.

       (g) Successors and Assigns.  Subject to applicable securities laws,
       this Warrant and the rights and obligations evidenced hereby shall
       inure to the benefit of and be binding upon the successors of the
       Company and the successors and permitted assigns of Holder.  The
       provisions of this Warrant are intended to be for the benefit of
       all Holders from time to time of this Warrant and shall be enforceable
       by any such Holder or holder of Warrant Shares.

       (h) Indemnification.  The Company agrees to indemnify and hold
       harmless Holder from and against any liabilities, obligations, losses,
       damages, penalties, actions, judgments, suits, claims, costs,
       attorneys' fees, expenses and disbursements of any kind which may be
       imposed upon, incurred by or asserted against Holder in any manner
       relating to or arising out of any failure by the Company to perform or
       observe in any material respect any of its covenants, agreements,
       undertakings or obligations set forth in this Warrant; provided, however,
       that the Company will not be liable hereunder to the extent that any
       liabilities, obligations, losses, damages, penalties, actions,
       judgments, suits, claims, costs, attorneys' fees, expenses or
       disbursements are found in a final non-appealable judgment by a court
       to have resulted from Holder's negligence, bad faith or willful
       misconduct in its capacity as a stockholder or warrantholder of the
       Company.

       (i) Amendment.  This Warrant may be modified or amended or the
       provisions hereof waived with the written consent of the Company and
       the Holder.

       (j) Severability.  Wherever possible, each provision of this Warrant
       shall be interpreted in such manner as to be effective and valid under
       applicable law, but if any provision of this Warrant shall be
       prohibited by or invalid under applicable law, such provision shall
       be ineffective to the extent of such prohibition or invalidity,
       without invalidating the remainder of such provisions or the remaining
       provisions of this Warrant.

       (k) Headings.  The headings used in this Warrant are for the
       convenience of reference only and shall not, for any purpose, be
       deemed a part of this Warrant.

       IN WITNESS WHEREOF, the Company has caused this Warrant to be executed
by its officer thereunto duly authorized.

																REGISTRATION RIGHTS AGREEMENT

REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of August ___,
2001, by and among Ultradata Systems, Inc., a Delaware corporation, with
headquarters located at 9375 Dielman Industrial Drive, St. Louis, MO 63132
(the "Company"), and the undersigned buyers (each, a "Buyer" and collectively,
the "Buyers").

WHEREAS:

    A. In connection with the Exchange Agreement by and among the parties
    hereto, dated August _____, 2001 (the "Exchange Agreement"), the Company
    has agreed, upon the terms and subject to the conditions of the Exchange
    Agreement, to issue to the Buyers (i) the Company's 11.25% Senior
    Subordinate Secured Convertible Promissory Notes (the "Convertible Notes"),
    which will be convertible into shares of the Company's common stock, $0.01
    par value per share (the "Common Stock") in accordance with the terms of
    the Convertible Notes and (ii) warrants ("Warrants") to purchase shares of
    Common stock (as issued upon exercise of the Warrants, the "Warrant
    Shares"), in exchange for shares of the Company's Series A Convertible
    Preferred Stock and certain warrants to purchase the Company's Common
    Stock at an exercise price of $5.00 per share.

    B. To induce the Buyers to execute and deliver the Exchange Agreement,
    the Company has agreed to provide certain registration rights under the
    Securities Act of 1933, as amended, and the rules and regulations
    thereunder, or any similar successor statute (collectively, the "Securities
    Act"), and applicable state securities laws.

NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company and the Buyers
hereby agree as follows:

    1. DEFINITIONS.

    As used in this Agreement, the following terms shall have the following
    meanings:

    - "Conversion Shares" means shares of Common Stock issued or issuable on
    conversion of the Convertible Notes.

    - "Investor" means a Buyer, any transferee or assignee thereof to whom a
    Buyer assigns its rights under this Agreement and who agrees to become
    bound by the provisions of this Agreement in accordance with Section 9
    and any transferee or assignee thereof to whom a transferee or assignee
    assigns its rights under this Agreement and who agrees to become bound by
    the provisions of this Agreement in accordance with Section 9.

    - "Person" means a corporation, a limited liability company, an
    association, a partnership, an organization, a business, an individual,
    a governmental or political subdivision thereof or a governmental agency.

    - "Register," "registered," and "registration" refer to a registration
    effected by preparing and filing one or more Registration Statements
    (as defined below) in compliance with the Securities Act and pursuant to
    Rule 415 under the Securities Act or any successor rule providing for
    offering securities on a continuous basis ("Rule 415"), and the
    declaration or ordering of effectiveness of such Registration Statement(s)
    by the United States Securities and Exchange Commission (the "SEC").

    - "Registrable Securities" means (i) the Conversion Shares issued or
    issuable upon conversion of the Convertible Notes, respectively, (ii) the
    Warrant Shares issued or issuable on exercise of the Warrants and (iii)
    any shares of capital stock issued or issuable with respect to the
    Conversion Shares, the Convertible Notes, the Warrant Shares or the
    Warrants as a result of any stock split, stock dividend, recapitalization,
    exchange or similar event or otherwise, without regard to any limitation
    on conversions of the Convertible Notes or exercise in the Warrants.

    - "Registration Statement" means a registration statement or registration
    statements of the Company filed under the Securities Act.

    2. REGISTRATION.

       a. Mandatory Registration.  The Company shall prepare, and, as soon as
       practicable, but in no event later than 14 days after the date hereof
       (the "Scheduled Filing Date"), file with the SEC a Registration
       Statement or Registration Statements (as is necessary) on Form S-3
       covering the resale of all of the Registrable Securities.  In the event
       that Form S-3 is unavailable for such a registration, the Company shall
       use such other form as is available for such a registration, subject
       to the provisions of Section 2(e).  The initial Registration Statement
       prepared pursuant hereto shall register for resale the lesser of (i) the
       number of shares of Common Stock authorized, but unissued and unreserved
       (but including shares reserved for issuance of Registrable Securities),
       or (ii) at least that number of shares of Common Stock equal to the
       product of (x) 2.0 and (y) the number of Registrable Securities as of
       the date immediately preceding the date the Registration Statement is
       initially filed with the SEC, subject to adjustment as provided in
       Section 3(b). The Company shall use its best efforts to have the
       Registration Statement declared effective by the SEC as soon as
       practicable, but in no event later than sixty (60) days after the
       Scheduled Filing Date, in the case of no review by the SEC, or seventy-
       five (75) days after the Scheduled Filing Date, in the case of a review
       by the SEC (the "Scheduled Effective Date").  The Company represents
       that no Person other than the Investors has the right to include any
       securities of the Company in the Registration Statement to be filed in
       accordance with this Section 2(a).  However, the Investors consent to
       the inclusion of Thornhill Group, Inc. and Influence Concept L.L.C. as
       selling securityholders in such Registration Statement to the extent of
       shares of Common Stock beneficially owned by them and registered under
       the Company's Registration Statement on Form SB-2, Registration No.
       333-39434.

       b. Piggy-Back Registrations.  Unless a Registration Statement is
       effective pursuant to 2(a) above, if at any time prior to the
       expiration of the Registration Period (as hereinafter defined) the
       Company proposes to file with the SEC a Registration Statement relating
       to an offering for its own account or the account of others under the
       Securities Act of any of its securities (other than a Registration
       Statement on Form S-4 or Form S-8 (or their equivalents at such time)
       relating to securities to be issued solely in connection with any
       acquisition of any entity or business or equity securities issuable in
       connection with stock option or other employee benefit plans) the
       Company shall promptly send to each Investor written notice of the
       Company's intention to file a Registration Statement and of such
       Investor's rights under this Section 2(b) and, if within twenty (20)
       days after receipt of such notice, such Investor shall so request in
       writing, the Company shall include in such Registration Statement all
       or any part of the Registrable Securities such Investor requests to be
       registered, subject to the priorities set forth in this Section 2(b)
       below.  No right to registration of Registrable Securities under this
       Section 2(b) shall be construed to limit any registration required
       under Section 2(a).  The obligations of the Company under this Section
       2(b) may be waived by Investors holding a majority of the Registrable
       Securities.  If an offering in connection with which an Investor is
       entitled to registration under this Section 2(b) is an underwritten
       offering, then each Investor whose Registrable Securities are included
       in such Registration Statement shall, unless otherwise agreed to by
       the Company, offer and sell such Registrable Securities in an
       underwritten offering using the same underwriter or underwriters and,
       subject to the provisions of this Agreement, on the same terms and
       conditions as other shares of Common Stock included in such underwritten
       offering.  If a registration pursuant to this Section 2(b) is to be an
       underwritten public offering and the managing underwriter(s) advise the
       Company in writing, that in their reasonable good faith opinion,
       marketing or other factors dictate that a limitation on the number of
       shares of Common Stock which may be included in the Registration
       Statement is necessary to facilitate and not adversely affect the
       proposed offering, then the Company shall include in such registration:
       (1) first, all securities the Company proposes to sell for its own
       account, (2) second, up to the full number of securities proposed to be
       registered for the account of the holders of securities entitled to
       inclusion of their securities in the Registration Statement by reason
       of demand registration rights, and (3) third, the securities requested
       to be registered by the Investors and other holders of securities
       entitled to participate in the registration, as of the date hereof,
       drawn from them pro rata based on the number each has requested to be
       included in such registration.

       c. Allocation of Registrable Securities.  The initial number of
       Registrable Securities included in any Registration Statement and each
       increase in the number of Registrable Securities included therein
       shall be allocated pro rata among the Investors based on the number of
       Registrable Securities held by each Investor at the time the
       Registration Statement covering such initial number of Registrable
       Securities or increase thereof is declared effective by the SEC.  In
       the event that an Investor sells or otherwise transfers any of such
       Investor's Registrable Securities, each transferee shall be allocated
       a pro rata portion of the then remaining number of Registrable
       Securities included in such Registration Statement for such transferor.
       Any shares of Common Stock included in a Registration Statement and
       which remain allocated to any Person which ceases to hold any
       Registrable Securities shall be allocated to the remaining Investors,
       pro rata based on the number of Registrable Securities then held by
       such Investors.

       d. Legal Counsel.  Subject to Section 5 hereof, the Buyers holding a
       majority of the Registrable Securities shall have the right to select
       one legal counsel to review and oversee any offering pursuant to this
       Section 2 ("Legal Counsel"), which shall be Snow Becker Krauss P.C.
       or such other counsel as thereafter designated by the holders of a
       majority of Registrable Securities.  The Company shall reasonably
       cooperate with Legal Counsel in performing the Company's obligations
       under this Agreement.

       e. Ineligibility for Form S-3.  In the event that Form S-3 is
       unavailable for any registration of Registrable Securities hereunder,
       the Company shall (i) register the sale of the Registrable Securities
       on another appropriate form and (ii) undertake to register the
       Registrable Securities on Form S-3 as soon as such form is available,
       provided that the Company shall maintain the effectiveness of the
       Registration Statement then in effect until such time as a Registration
       Statement on Form S-3 covering the Registrable Securities has been
       declared effective by the SEC.

       f. Sufficient Number of Shares Registered.  If the number of shares
       available under a Registration Statement filed pursuant to Section 2(a)
       is insufficient to cover all of the Registrable Securities which such
       Registration Statement is required to cover or an Investor's allocated
       portion of the Registrable Securities pursuant to Section 2(c), the
       Company shall amend the Registration Statement, or file a new
       Registration Statement (on the short form available therefor, if
       applicable), or both, so as to cover at least 300% of such Registrable
       Securities (based on the market price of the Common Stock), in each
       case, as soon as practicable, but in any event not later than fifteen
       (15) days after the necessity therefor arises (each such date, an
       "Additional Scheduled Filing Date").  The Company shall use it best
       efforts to cause such amendment and/or new Registration Statement to
       become effective as soon as practicable following the filing thereof,
       but in no event later than sixty (60) days after the Additional
       Scheduled Filing Date (each such date, an "Additional Scheduled Effective
       Date").  For purposes of the foregoing provision, the number of shares
       available under a Registration Statement shall be deemed "insufficient
       to cover all of the Registrable Securities" if at any time the number
       of Registrable Securities issued or issuable upon conversion of the
       Convertible Notes and exercise of the Warrants covered by such
       Registration Statement is greater than the quotient determined by
       dividing (i) the number of shares of Common Stock available for resale
       under such Registration Statement by (ii) 1.5.  For purposes of the
       calculation set forth in the foregoing sentence, any restrictions on
       the convertibility of the Convertible Notes or exercisability of Warrant
       shall be disregarded and such calculation shall assume that the
       Convertible Notes are then convertible and exercisable, respectively,
       into shares of Common Stock at the then prevailing Conversion Rate (as
       defined in the Company's Certificate of Designations or the terms of
       the Convertible Notes) and the Warrants are exercisable at the then
       prevailing Exercise Price (as defined in the Warrants).

    3. RELATED OBLIGATIONS.

       Whenever an Investor has requested that any Registrable Securities be
       registered pursuant to Section 2(b) or at such time as the Company is
       obligated to file a Registration Statement with the SEC pursuant to
       Section 2(a) or 2(f), the Company will use its best efforts to effect
       the registration of the Registrable Securities in accordance with the
       intended method of disposition thereof and, pursuant thereto, the
       Company shall have the following obligations:

       a. The Company shall promptly prepare and file with the SEC a
       Registration Statement with respect to the Registrable Securities (on
       or prior to the Scheduled Filing Date) for the registration of
       Registrable Securities pursuant to Section 2(a) and use its best
       efforts to cause such Registration Statement relating to the
       Registrable Securities to become effective as soon as possible after
       such filing (but, in no event later than sixty (60) days after such
       Scheduled Filing Date).  The Company shall not file any other
       Registration Statement with respect to any of its securities between
       the date hereof and the filing date of such Registration Statement
       (other than a Registration Statement on Form S-8 (or its equivalent
       at such time)).  The Company shall keep the Registration Statement
       required to be filed hereunder effective pursuant to Rule 415 at all
       times until the earlier of (i) the date as of which the Investors may
       sell all of the Registrable Securities covered by such Registration
       Statement without restriction pursuant to Rule 144(k) promulgated under
       the Securities Act (or successor thereto) or (ii) the date on which
       (A) the Investors shall have sold all the Registrable Securities
       covered by such Registration Statement and (B) none of the Convertible
       Notes or Warrants is outstanding (the "Registration Period"), which
       Registration Statement (including any amendments or supplements thereto
       and prospectuses contained therein) shall not contain any untrue
       statement of a material fact or omit to state a material fact required
       to be stated therein, or necessary to make the statements therein, in
       light of the circumstances in which they were made, not misleading.
       The term "best efforts" shall mean, among other things, that the Company
       shall submit to the SEC, within three business days after the Company
       learns that no review of a particular Registration Statement will be
       made by the staff of the SEC or that the staff has no further comments
       on the Registration Statement, as the case may be, a request for
       acceleration of effectiveness of such Registration Statement to a time
       and date not later than 48 hours after the submission of such request.

       b. The Company shall prepare and file with the SEC such amendments
       (including post-effective amendments) and supplements to a Registration
       Statement and the prospectus used in connection with such Registration
       Statement, which prospectus is to be filed pursuant to Rule 424
       promulgated under the Securities Act, as may be necessary to keep such
       Registration Statement effective at all times during the Registration
       Period, and, during such period, comply with the provisions of the
       Securities Act with respect to the disposition of all Registrable
       Securities of the Company covered by such Registration Statement until
       such time as all of such Registrable Securities shall have been disposed
       of in accordance with the intended methods of disposition by the seller
       or sellers thereof as set forth in such Registration Statement.  In the
       case of amendments and supplements to a Registration Statement which are
       required to be filed pursuant to this Agreement (including pursuant to
       this Section 3(b)) by reason of the Company filing a report on Form
       10-KSB, Form 10-QSB or Form 8-K or any analogous report under the
       Securities Exchange Act of 1934, as amended (the "Exchange Act"), the
       Company shall file such amendments or supplements with the SEC on the
       same day on which the Exchange Act report is filed which created the
       requirement for the Company to amend or supplement the Registration
       Statement.

       c. The Company shall (a) permit Legal Counsel to review and comment upon
       (i) the Registration Statement at least seven (7) days prior to its
       filing with the SEC and (ii) all other Registration Statements and all
       amendments and supplements to all Registration Statements within a
       reasonable number of days prior to the their filing with the SEC and
       (b) not file any document in a form to which Legal Counsel reasonably
       objects.  The Company shall not submit a request for acceleration of
       the effectiveness of a Registration Statement or any amendment or
       supplement thereto without the prior approval of Legal Counsel, which
       approval shall not be unreasonably withheld.  The Company shall furnish
       to Legal Counsel, without charge, (i) any correspondence from the SEC
       or the staff of the SEC to the Company or its representatives relating
       to any Registration Statement, (ii) promptly after the same is prepared
       and filed with the SEC, one copy of any Registration Statement and any
       amendment(s) thereto, including, upon request by counsel to the
       Investors, financial statements and schedules, all documents
       incorporated therein by reference and all exhibits and (iii) upon the
       effectiveness of any Registration Statement, one copy of the prospectus
       included in such Registration Statement and all amendments and
       supplements thereto.

       d. The Company shall furnish to each Investor whose Registrable
       Securities are included in any Registration Statement, without charge,
       (i) promptly after the same is prepared and filed with the SEC, at
       least one copy of such Registration Statement and any amendment(s)
       thereto, including, upon request by counsel to the Investors, financial
       statements and schedules, all documents incorporated therein by
       reference, all exhibits and each preliminary prospectus, (ii) upon the
       effectiveness of any Registration Statement, ten (10) copies of the
       prospectus included in such Registration Statement and all amendments
       and supplements thereto (or such other number of copies as such
       Investor may reasonably request) and (iii) such other documents,
       including copies of any preliminary or final prospectus, as such
       Investor may reasonably request from time to time in order to
       facilitate the disposition of the Registrable Securities owned by such
       Investor.

       e. The Company shall use reasonable efforts to (i) register and qualify
       the Registrable Securities covered by a Registration Statement under
       such other securities or "blue sky" laws of such jurisdictions in the
       United States as Legal Counsel or any Investor reasonably requests,
       (ii) prepare and file in those jurisdictions, such amendments (including
       post-effective amendments) and supplements to such registrations and
       qualifications as may be necessary to maintain the effectiveness thereof
       during the Registration Period, (iii) take such other actions as may be
       necessary to maintain such registrations and qualifications in effect
       at all times during the Registration Period, and (iv) take all other
       actions reasonably necessary or advisable to qualify the Registrable
       Securities for sale in such jurisdictions; provided, however, that the
       Company shall not be required in connection therewith or as a condition
       thereto to (x) qualify to do business in any jurisdiction where it would
       not otherwise be required to qualify but for this Section 3(e),
       (y) subject itself to general taxation in any such jurisdiction, or
       (z) file a general consent to service of process in any such
       jurisdiction.  The Company shall promptly notify Legal Counsel and
       each Investor who holds Registrable Securities of the receipt by the
       Company of any notification with respect to the suspension of the
       registration or qualification of any of the Registrable Securities for
       sale under the securities or "blue sky" laws of any jurisdiction in the
       United States or its receipt of actual notice of the initiation or
       threatening of any proceeding for such purpose.

       f. In the event Investors who hold a majority of the Registrable
       Securities being offered in the offering select underwriters for the
       offering, the Company shall enter into and perform its obligations
       under an underwriting agreement, in usual and customary form, including,
       without limitation, customary indemnification and contribution
       obligations, with the underwriters of such offering; provided, however,
       that the Company shall have the right to consent to the selection of
       such underwriter, which consent shall not be unreasonably withheld.

       g. As promptly as practicable after becoming aware of such event, the
       Company shall notify Legal Counsel and each Investor in writing of the
       happening of any event as a result of which the prospectus included in
       a Registration Statement, as then in effect, includes an untrue
       statement of a material fact or omits to state a material fact required
       to be stated therein or necessary to make the statements therein, in
       light of the circumstances under which they were made, not misleading,
       and promptly prepare a supplement or amendment to such Registration
       Statement to correct such untrue statement or omission, and deliver
       ten (10) copies of such supplement or amendment to Legal Counsel and
       each Investor (or such other number of copies as Legal Counsel or such
       Investor may reasonably request).  The Company shall also promptly
       notify Legal Counsel and each Investor in writing (i) when a prospectus
       or any prospectus supplement or post-effective amendment has been
       filed, and when a Registration Statement or any post-effective amendment
       has become effective (notification of such effectiveness shall be
       delivered to Legal Counsel and each Investor by facsimile on the same
       day of such effectiveness and by overnight mail), (ii) of any request
       by the SEC for amendments or supplements to a Registration Statement
       or related prospectus or related information, and (iii) of the Company's
       reasonable determination that a post-effective amendment to a
       Registration Statement would be appropriate.

       h. The Company shall use its best efforts to prevent the issuance of a
       ny stop order or other suspension of effectiveness of a Registration
       Statement, or the suspension of the qualification of any of the
       Registrable Securities for sale in any jurisdiction and, if such an
       order or suspension is issued, to obtain the withdrawal of such order
       or suspension at the earliest possible moment and to notify Legal
       Counsel and each Investor who holds Registrable Securities being sold
       (and, in the event of an underwritten offering, the managing
       underwriters) of the issuance of such order and the resolution thereof
       or its receipt of actual notice of the initiation or threat of any
       proceeding for such purpose.

       i. At the request of any Investor, the Company shall furnish to such
       Investor, on the date of the effectiveness of the Registration Statement
       and thereafter from time to time on such dates as an Investor may
       reasonably request (i) if required by an underwriter, a letter, dated
       such date, from the Company's independent certified public accountants
       in form and substance as is customarily given by independent certified
       public accountants to underwriters in an underwritten public offering,
       addressed to the underwriters, and (ii) an opinion, dated as of such
       date, of counsel representing the Company for purposes of such
       Registration Statement, in form, scope and substance as is customarily
       given in an underwritten public offering, addressed to the underwriters
       and the Investors.

       j. The Company shall make available for inspection by (i) any Investor,
       (ii) Legal Counsel, (iii) any underwriter participating in any
       disposition pursuant to a Registration Statement, (iv) one firm of
       accountants or other agents retained by the Investors and (v) one firm
       of attorneys retained by such underwriters (collectively, the
       "Inspectors") all pertinent financial and other records, and pertinent
       corporate documents and properties of the Company (collectively, the
       "Records"), as shall be reasonably deemed necessary by each Inspector,
       and cause the Company's officers, directors and employees to supply all
       information which any Inspector may reasonably request; provided,
       however, that each Inspector shall hold in strict confidence and shall
       not make any disclosure (except to an Investor) or use of any Records
       or other information which the Company determines in good faith to be
       confidential, and of which determination the Inspectors are so notified,
       unless (a) the disclosure of such Records is necessary to avoid or
       correct a misstatement or omission in any Registration Statement or is
       otherwise required under the Securities Act, (b) the release of such
       Records is ordered pursuant to a final, non-appealable subpoena or order
       from a court or government body of competent jurisdiction, or (c) the
       information in such Records has been made generally available to the
       public other than by disclosure in violation of this or any other
       agreement of which the Inspector has knowledge.  Each Investor agrees
       that it shall, upon learning that disclosure of such Records is sought
       in or by a court or governmental body of competent jurisdiction or
       through other means, give prompt notice to the Company and allow the
       Company, at its expense, to undertake appropriate action to prevent
       disclosure of, or to obtain a protective order for, the Records deemed
       confidential.

       k. The Company shall hold in confidence and not make any disclosure of
       information concerning an Investor provided to the Company unless
       (i) disclosure of such information is necessary to comply with federal
       or state securities laws, (ii) the disclosure of such information is
       necessary to avoid or correct a misstatement or omission in any
       Registration Statement, (iii) the release of such information is ordered
       pursuant to a subpoena or other final, non-appealable order from a court
       or governmental body of competent jurisdiction, or (iv) such information
       has been made generally available to the public other than by disclosure
       in violation of this Agreement or any other agreement.  The Company
       agrees that it shall, upon learning that disclosure of such information
       concerning an Investor is sought in or by a court or governmental body
       of competent jurisdiction or through other means, give prompt written
       notice to such Investor and allow such Investor, at the Investor's
       expense, to undertake appropriate action to prevent disclosure of, or
       to obtain a protective order for, such information.

       l. The Company shall use its best efforts either to (i) cause all the
       Registrable Securities covered by a Registration Statement to be listed
       on each securities exchange on which securities of the same class or
       series issued by the Company are then listed, if any, if the listing of
       such Registrable Securities is then permitted under the rules of such
       exchange, (ii) secure the designation and quotation of all the
       Registrable Securities covered by the Registration Statement on the
       Nasdaq SmallCap Market, or (iii) secure the inclusion for quotation on
       the over-the-counter market on the electronic bulletin board for such
       Registrable Securities and, without limiting the generality of the
       foregoing, to arrange for at least two market makers to register with
       the National Association of Securities Dealers, Inc. ("NASD") as such
       with respect to such Registrable Securities.  The Company shall pay all
       fees and expenses in connection with satisfying its obligation under
       this Section 3(l).

       m. The Company shall cooperate with the Investors who hold Registrable
       Securities being offered and, to the extent applicable, any managing
       underwriter or underwriters, to facilitate the timely preparation and
       delivery of certificates (not bearing any restrictive legend)
       representing the Registrable Securities to be offered pursuant to a
       Registration Statement and enable such certificates to be in such
       denominations or amounts, as the case may be, as the managing
       underwriter or underwriters, if any, or, if there is no managing
       underwriter or underwriters, the Investors may reasonably request and
       registered in such names as the managing underwriter or underwriters,
       if any, or the Investors may request.

       n. The Company shall provide a transfer agent and registrar of all such
       Registrable Securities not later than the effective date of such
       Registration Statement.

       o. If requested by the managing underwriters or an Investor, the Company
       shall (i) immediately incorporate in a prospectus supplement or post-
       effective amendment such information as the managing underwriters and
       the Investors agree should be included therein relating to the sale and
       distribution of Registrable Securities, including, without limitation,
       information with respect to the number of Registrable Securities being
       sold to such underwriters, the purchase price being paid therefor by
       such underwriters and any other terms of the underwritten (or best
       efforts underwritten) offering of the Registrable Securities to be sold
       in such offering; (ii) make all required filings of such prospectus
       supplement or post-effective amendment as soon as notified of the
       matters to be incorporated in such prospectus supplement or post-
       effective amendment; and (iii) supplement or make amendments to any
       Registration Statement if requested by an Investor or any underwriter
       of such Registrable Securities.

       p. The Company shall use its best efforts to cause the Registrable
       Securities covered by the applicable Registration Statement to be
       registered with or approved by such other governmental agencies or
       authorities as may be necessary to consummate the disposition of such
       Registrable Securities.

       q. The Company shall make generally available to its security holders
       as soon as practical, but not later than 90 days after the close of
       the period covered thereby, an earnings statement (in form complying
       with the provisions of Rule 158 under the Securities Act) covering a
       twelve-month period beginning not later than the first day of the
       Company's fiscal quarter next following the effective date of the
       Registration Statement.

       r. The Company shall otherwise use its best efforts to comply with all
       applicable rules and regulations of the SEC in connection with any
       registration hereunder.

       s. Within two (2) business days after a Registration Statement which
       covers applicable Registrable Securities is ordered effective by the
       SEC, the Company shall deliver, and shall cause legal counsel for the
       Company to deliver, to the transfer agent for such Registrable
       Securities (with copies to the Investors whose Registrable Securities
       are included in such Registration Statement) confirmation that such
       Registration Statement has been declared effective by the SEC in the
       form attached hereto as Exhibit A.

       t. The Company shall take all other reasonable actions necessary to
       expedite and facilitate disposition by the Investors of Registrable
       Securities pursuant to a Registration Statement.

       u. Notwithstanding anything to the contrary in Section 3(g), at any
       time after the Registration Statement has been declared effective,
       the Company may delay the disclosure of material, non-public
       information concerning the Company the disclosure of which at the
       time is not, in the good faith opinion of the Board of Directors of
       the Company and its counsel, in the best interest of the Company and,
       in the opinion of counsel to the Company, otherwise required (a "Grace
       Period"); provided, that the Company shall promptly (i) notify the
       Investors in writing of the existence of material, non-public
       information giving rise to a Grace Period and the date on which the
       Grace Period will begin, and (ii) notify the Investors in writing of
       the date on which the Grace Period ends; and, provided further, that
       during any consecutive 365 day period, there shall be only one Grace
       Period, such Grace Period not to exceed 20 days in the aggregate (an
       "Allowable Grace Period").  For purposes of determining the length of
       a Grace Period above, the Grace Period shall begin on and include the
       date the Investors receive the notice referred to in clause (i) above
       and shall end on and include the date the Investors receive the notice
       referred to in clause (ii) above.  During the length of any Grace
       Period, the Investors will continue to be able to convert their
       Convertible Notes into Common Stock pursuant to Section 3 of the
       Convertible Notes, but shall not be able to sell the Conversion Shares.
       The provisions of Section 4(b) of the Convertible Notes shall not be
       applicable during the period of any Allowable Grace Period.  Upon
       expiration of the Allowable Grace Period, the Company shall again be
       bound by the first sentence of Section 3(g) with respect to the
       information giving rise thereto.

       v. Each of the following events shall constitute a "Registration
       Default" for purposes of this Agreement:

          (i) the Company's failure to file a Registration Statement by the
          Scheduled Filing Date or Additional Scheduled Filing Date thereof,
          as appropriate;

          (ii) the SEC's failure to declare a Registration Statement effective
          on or before the Scheduled Effective Date or Additional Scheduled
          Effective Date thereof, as appropriate, except where the failure to
          meet such deadline is the result solely of actions by the holders of
          Registrable Securities;

          (iii) the Company's failure to request acceleration of the
          effectiveness of a Registration Statement within three (3) business
          days after the SEC has notified the Company that it may file such
          an acceleration request as required by Section 3(a) hereof;

          (iv) the Investors' inability to sell all Registrable Securities
          pursuant to an effective Registration Statement (whether because
          of a failure to keep the Registration Statement effective, to
          disclose such information as is necessary for sales to be made
          pursuant to the Registration Statement, to register sufficient
          shares of Common Stock or otherwise); or

          (v) the aggregate days of Grace Period exceed the Allowable Grace
          Period.

       Upon the occurrence of a Registration Default, the Company shall pay
       each Investor an amount determined in accordance with the following
       formula for each day of such Registration Default:

          .0005 x P x N

          where

          P = the Closing Ask Price (as defined in the Convertible Notes) of
              the Company's Common Stock on such day; and

          N = the number of Registrable Securities that such Investor holds
              or may acquire pursuant to conversion of the Convertible Notes
              or exercise of in-the-money Warrants on such day (without giving
              effect to any limitations on conversion or exercise).

       The Company shall pay such amount on demand by an Investor made at any
       time during the continuance or after termination of such Registration
       Default.  If the Company does not remit payment of the amount due to
       such Investor, the Company will pay the Investor's reasonable costs of
       collection, including attorneys' fees.  An Investor's right to demand
       such payment shall be in addition to any other rights it may have
       under this Agreement, the Exchange Agreement, the Convertible Notes,
       the Security Agreement, or otherwise, including its rights of
       Redemption under Section 4(b) of the Convertible Notes.

    4. OBLIGATIONS OF THE INVESTORS.

       a. At least seven (7) business days prior to the first anticipated
       filing date of a Registration Statement, the Company shall notify each
       Investor in writing of the information the Company requires from each
       such Investor if such Investor elects to have any of such Investor's
       Registrable Securities included in such Registration Statement.  It
       shall be a condition precedent to the obligations of the Company to
       complete the registration pursuant to this Agreement with respect to
       the Registrable Securities of a particular Investor that such Investor
       shall furnish to the Company such information regarding itself, the
       Registrable Securities held by it and the intended method of disposition
       of the Registrable Securities held by it as shall be reasonably required
       to effect the registration of such Registrable Securities and shall
       execute such documents in connection with such registration as the
       Company may reasonably request.

       b. Each Investor by such Investor's acceptance of the Registrable
       Securities agrees to cooperate with the Company as reasonably requested
       by the Company in connection with the preparation and filing of any
       Registration Statement hereunder, unless such Investor has notified the
       Company in writing of such Investor's election to exclude all of such
       Investor's Registrable Securities from such Registration Statement.

       c. In the event any Investor elects to participate in an underwritten
       public offering pursuant to Section 2(b), each such Investor agrees to
       enter into and perform such Investor's obligations under an underwriting
       agreement, in usual and customary form, including, without limitation,
       customary indemnification and contribution obligations, with the
       managing underwriter of such offering and take such other actions as
       are reasonably required in order to expedite or facilitate the
       disposition of the Registrable Securities.

       d. Each Investor agrees that, upon receipt of any notice from the
       Company of the happening of any event of the kind described in Section
       3(h) or the first sentence of Section 3(g), such Investor will
       immediately discontinue disposition of Registrable Securities pursuant
       to any Registration Statement(s) covering such Registrable Securities
       until such Investor's receipt of the copies of the supplemented or
       amended prospectus contemplated by Section 3(h) or the first sentence
       of Section 3(g).

       e. No Investor may participate in any underwritten registration hereunder
       unless such Investor (i) agrees to sell such Investor's Registrable
       Securities on the basis provided in any underwriting arrangements
       approved by the Investors entitled hereunder to approve such
       arrangements, (ii) completes and executes all questionnaires, powers
       of attorney, indemnities, underwriting agreements and other documents
       reasonably required under the terms of such underwriting arrangements,
       and (iii) agrees to pay its pro rata share of all underwriting discounts
       and commissions.

       f. Each Investor agrees not to take any action to cause such Investor to
       become a registered broker dealer as defined under the Exchange Act or
       to effect any change to such Investor's status that would preclude the
       Company from using Form S-3 for the Registration Statement.

    5. EXPENSES OF REGISTRATION.

       All reasonable expenses, other than expenses incurred pursuant to
       Section 3(j)(iv) and (v) and underwriting discounts and commissions,
       incurred in connection with registrations, filings or qualifications
       pursuant to Sections 2 and 3, including, without limitation, all
       registration, listing and qualifications fees, printers and accounting
       fees, and fees and disbursements of counsel for the Company, shall be
       paid by the Company.

    6. INDEMNIFICATION.

       In the event any Registrable Securities are included in a Registration
       Statement under this Agreement:

       a. To the fullest extent permitted by law, the Company will, and hereby
       does, indemnify, hold harmless and defend each Investor who holds such
       Registrable Securities, the directors, officers, partners, employees,
       agents, representatives of, and each Person, if any, who controls any
       Investor within the meaning of the Securities Act or the Exchange Act,
       and any underwriter (as defined in the Securities Act) for the
       Investors, and the directors and officers of, and each Person, if any,
       who controls, any such underwriter within the meaning of the Securities
       Act or the Exchange Act (each, an "Indemnified Person"), against any
       losses, claims, damages, liabilities, judgments, fines, penalties,
       charges, costs, attorneys' fees, amounts paid in settlement or expenses,
       joint or several, (collectively, "Claims") incurred in investigating,
       preparing or defending any action, claim, suit, inquiry, proceeding,
       investigation or appeal taken from the foregoing by or before any court
       or governmental, administrative or other regulatory agency or body or
       the SEC, whether pending or threatened, whether or not an indemnified
       party is or may be a party thereto ("Indemnified Damages"), to which
       any of them may become subject insofar as such Claims (or actions or
       proceedings, whether commenced or threatened, in respect thereof) arise
       out of or are based upon: (i) any untrue statement or alleged untrue
       statement of a material fact in a Registration Statement or any post-
       effective amendment thereto or in any filing made in connection with
       the qualification of the offering under the securities or other "blue
       sky" laws of any jurisdiction in which Registrable Securities are
       offered ("Blue Sky Filing"), or the omission or alleged omission to
       state a material fact required to be stated therein or necessary to
       make the statements therein not misleading, (ii) any untrue statement
       or alleged untrue statement of a material fact contained in any
       preliminary prospectus if used prior to the effective date of such
       Registration Statement, or contained in the final prospectus (as
       amended or supplemented, if the Company files any amendment thereof or
       supplement thereto with the SEC) or the omission or alleged omission to
       state therein any material fact necessary to make the statements made
       therein, in light of the circumstances under which the statements
       therein were made, not misleading, (iii) any violation or alleged
       violation by the Company of the Securities Act, the Exchange Act, any
       other law, including, without limitation, any state securities law, or
       any rule or regulation thereunder relating to the offer or sale of the
       Registrable Securities pursuant to a Registration Statement or (iv) any
       material violation of this Agreement (the matters in the foregoing
       clauses (i) through (iv) being, collectively, "Violations").  The
       Company shall reimburse the Investors and each such underwriter or
       controlling person, promptly as such expenses are incurred and are due
       and payable, for any legal fees or other reasonable expenses incurred
       by them in connection with investigating or defending any such Claim.
       Notwithstanding anything to the contrary contained herein, the
       indemnification agreement contained in this Section 6(a): (i) shall
       not apply to a Claim by an Indemnified Person arising out of or based
       upon a Violation which occurs in reliance upon and in conformity with
       information furnished in writing to the Company by such Indemnified
       Person or underwriter for such Indemnified Person expressly for use
       in connection with the preparation of the Registration Statement or
       any such amendment thereof or supplement thereto, if such prospectus
       was timely made available by the Company pursuant to Section 3(d);
       (ii) with respect to any preliminary prospectus, shall not inure to
       the benefit of any such person from whom the person asserting any such
       Claim purchased the Registrable Securities that are the subject thereof
       (or to the benefit of any person controlling such person) if the untrue
       statement or omission of material fact contained in the preliminary
       prospectus was corrected in the prospectus, as then amended or
       supplemented, if such prospectus was timely made available by the
       Company pursuant to Section 3(d), and the Indemnified Person was
       promptly advised in writing not to use the incorrect prospectus prior
       to the use giving rise to a violation and such Indemnified Person,
       notwithstanding such advice, used it; (iii) shall not be available to
       the extent such Claim is based on a failure of the Investor to deliver
       or to cause to be delivered the prospectus made available by the
       Company, if such prospectus was timely made available by the Company
       pursuant to Section 3(d); and (iv) shall not apply to amounts paid in
       settlement of any Claim if such settlement is effected without the prior
       written consent of the Company, which consent shall not be unreasonably
       withheld.  Such indemnity shall remain in full force and effect
       regardless of any investigation made by or on behalf of the Indemnified
       Person and shall survive the transfer of the Registrable Securities by
       the Investors pursuant to Section 9.

       b. In connection with any Registration Statement in which an Investor is
       participating, each such Investor agrees to severally and not jointly
       indemnify, hold harmless and defend, to the same extent and in the same
       manner as is set forth in Section 6(a), the Company, each of its
       directors, each of its officers who signs the Registration Statement,
       each Person, if any, who controls the Company within the meaning of the
       Securities Act or the Exchange Act (collectively and together with an
       Indemnified Person, an "Indemnified Party"), against any Claim or
       Indemnified Damages to which any of them may become subject, under the
       Securities Act, the Exchange Act or otherwise, insofar as such Claim or
       Indemnified Damages arise out of or are based upon any Violation, in
       each case to the extent, and only to the extent, that such Violation
       occurs in reliance upon and in conformity with written information
       furnished to the Company by such Investor expressly for use in
       connection with such Registration Statement; and, subject to Section
       6(d), such Investor will reimburse any legal or other expenses
       reasonably incurred by them in connection with investigating or
       defending any such Claim; provided, however, that the indemnity
       agreement contained in this Section 6(b) and the agreement with respect
       to contribution contained in Section 7 shall not apply to amounts paid
       in settlement of any Claim if such settlement is effected without the
       prior written consent of such Investor, which consent shall not be
       unreasonably withheld; provided, further, however, that the Investor
       shall be liable under this Section 6(b) for only that amount of a Claim
       or Indemnified Damages as does not exceed the net proceeds to such
       Investor as a result of the sale of Registrable Securities pursuant to
       such Registration Statement.  Such indemnity shall remain in full force
       and effect regardless of any investigation made by or on behalf of such
       Indemnified Party and shall survive the transfer of the Registrable
       Securities by the Investors pursuant to Section 9.  Notwithstanding
       anything to the contrary contained herein, the indemnification agreement
       contained in this Section 6(b) with respect to any preliminary
       prospectus shall not inure to the benefit of any Indemnified Party if
       the untrue statement or omission of material fact contained in the
       preliminary prospectus was corrected on a timely basis in the prospectus
       and such prospectus was provided to Investors as required, as then
       amended or supplemented.

       c. The Company shall be entitled to receive indemnities from
       underwriters, selling brokers, dealer managers and similar securities
       industry professionals participating in any distribution, to the same
       extent as provided above, with respect to information such persons so
       furnished in writing expressly for inclusion in the Registration
       Statement.

       d. Promptly after receipt by an Indemnified Person or Indemnified Party
       under this Section 6 of notice of the commencement of any action or
       proceeding (including any governmental action or proceeding) involving
       a Claim, such Indemnified Person or Indemnified Party shall, if a Claim
       in respect thereof is to be made against any indemnifying party under
       this Section 6, deliver to the indemnifying party a written notice of
       the commencement thereof, and the indemnifying party shall have the
       right to participate in, and, to the extent the indemnifying party so
       desires, jointly with any other indemnifying party similarly noticed,
       to assume control of the defense thereof with counsel mutually
       satisfactory to the indemnifying party and the Indemnified Person or
       the Indemnified Party, as the case may be; provided, however, that an
       Indemnified Person or Indemnified Party shall have the right to retain
       its own counsel with the fees and expenses to be paid by the
       indemnifying party, if, in the reasonable opinion of counsel retained
       by the indemnifying party, the representation by such counsel of the
       Indemnified Person or Indemnified Party and the indemnifying party
       would be inappropriate due to actual or potential differing interests
       between such Indemnified Person or Indemnified Party and any other
       party represented by such counsel in such proceeding.  The Company
       shall pay reasonable fees for only one separate legal counsel for the
       Investors, and such legal counsel shall be selected by the Investors
       holding a majority of the issued or issuable Registrable Securities
       included in the Registration Statement to which the Claim relates.
       The Indemnified Party or Indemnified Person shall cooperate fully with
       the indemnifying party in connection with any negotiation 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 or Indemnified Person which relates to such action or
       claim.  The indemnifying party shall keep the Indemnified Party or
       Indemnified Person fully apprised at all times as to the status of the
       defense or any settlement negotiations with respect thereto.  No
       indemnifying party shall be liable for any settlement of any action,
       claim or proceeding effected without its written consent; provided,
       however, that the indemnifying party shall not unreasonably withhold,
       delay or condition its consent.  No indemnifying party shall, without
       the consent of the Indemnified Party or Indemnified Person, consent to
       entry of any judgment or enter into any settlement or other compromise
       which does not include as an unconditional term thereof the giving by
       the claimant or plaintiff to such Indemnified Party or Indemnified
       Person of a release from all liability in respect to such claim or
       litigation.  Following indemnification as provided for hereunder, the
       indemnifying party shall be subrogated to all rights of the Indemnified
       Party or Indemnified Person with respect to all third parties, firms
       or corporations relating to the matter for which indemnification has
       been made.  The failure to deliver written notice to the indemnifying
       party within a reasonable time of the commencement of any such action
       shall not relieve such indemnifying party of any liability to the
       Indemnified Person or Indemnified Party under this Section 6, except
       to the extent that the indemnifying party is prejudiced in its ability
       to defend such action.

       e. The indemnification required by this Section 6 shall be made by
       periodic payments of the amount thereof during the course of the
       investigation or defense, as and when bills are received or Indemnified
       Damages are incurred.

       f. The indemnity agreements contained herein shall be in addition to
       (i) any cause of action or similar right of the Indemnified Party or
       Indemnified Person against the indemnifying party or others, and
       (ii) any liabilities the indemnifying party may be subject to pursuant
       to the law.

    7. CONTRIBUTION.

       To the extent any indemnification by an indemnifying party is prohibited
       or limited by law, the indemnifying party agrees to make the maximum
       contribution with respect to any amounts for which it would otherwise
       be liable under Section 6 to the fullest extent permitted by law;
       provided, however, that:  (i) no seller of Registrable Securities
       guilty of fraudulent misrepresentation (within the meaning of Section
       11(f) of the Securities Act) shall be entitled to contribution from any
       seller of Registrable Securities who was not guilty of fraudulent
       misrepresentation; and (ii) contribution by any seller of Registrable
       Securities shall be limited in amount to the net amount of proceeds
       received by such seller from the sale of such Registrable Securities.

    8. REPORTS UNDER THE EXCHANGE ACT.

       With a view to making available to the Investors the benefits of Rule
       144 promulgated under the Securities Act or any other similar rule or
       regulation of the SEC that may at any time permit the Investors to sell
       securities of the Company to the public without registration ("Rule
       144"), during the Registration Period, the Company agrees to:

       a. make and keep public information available, as those terms are
       understood and defined in Rule 144;

       b. file with the SEC in a timely manner all reports and other documents
       required of the Company under the Securities Act and the Exchange Act
       so long as the Company remains subject to such requirements (it being
       understood that nothing herein shall limit the Company's obligations
       under Section 6.5 or 6.14 of the Exchange Agreement) and the filing of
       such reports and other documents is required for the applicable
       provisions of Rule 144; and

       c. furnish to each Investor so long as such Investor owns Registrable
       Securities, promptly upon request, (i) a written statement by the
       Company that it has complied with the reporting requirements of Rule
       144, the Securities Act and the Exchange Act, (ii) a copy of the most
       recent annual or quarterly report of the Company and such other reports
       and documents so filed by the Company, and (iii) such other information
       as may be reasonably requested to permit the investors to sell such
       securities pursuant to Rule 144 without registration.

    9. ASSIGNMENT OF REGISTRATION RIGHTS.

       The rights under this Agreement shall be automatically assignable by the
       Investors to any transferee of all or any portion of Registrable
       Securities if: (i) the Investor agrees in writing with the transferee or
       assignee to assign such rights, and a copy of such agreement is furnished
       to the Company within a reasonable time after such assignment; (ii) the
       Company is, within a reasonable time after such transfer or assignment,
       furnished with written notice of (a) the name and address of such
       transferee or assignee, and (b) the securities with respect to which
       such registration rights are being transferred or assigned; (iii)
       immediately following such transfer or assignment the further
       disposition of such securities by the transferee or assignee is
       restricted under the Securities Act and applicable state securities
       laws; (iv) at or before the time the Company receives the written notice
       contemplated by clause (ii) of this sentence the transferee or assignee
       agrees in writing with the Company to be bound by all of the provisions
       contained herein; and (v) such transfer shall have been made in
       accordance with the applicable requirements of the Exchange Agreement.

   10. AMENDMENT OF REGISTRATION RIGHTS.

       Provisions of this Agreement may be amended and the observance thereof
       may be waived (either generally or in a particular instance and either
       retroactively or prospectively), only with the written consent of the
       Company and Investors who then hold or have the right to acquire two-
       thirds (?) of the Registrable Securities.  Any amendment or waiver
       effected in accordance with this Section 10 shall be binding upon each
       Investor and the Company.  No such amendment shall be effective to the
       extent that it applies to less than all of the holders of the
       Registrable Securities.  No consideration shall be offered or paid to
       any Person to amend or consent to a waiver or modification of any
       provision of any of this Agreement unless the same consideration also
       is offered to all of the parties to this Agreement.

   11. MISCELLANEOUS.

       a. A Person is deemed to be a holder of Registrable Securities whenever
       such Person owns or is deemed to own of record such Registrable
       Securities or derivatives of Registrable Securities.  If the Company
       receives conflicting instructions, notices or elections from two or more
       Persons with respect to the same Registrable Securities, the Company
       shall act upon the basis of instructions, notice or election received
       from the registered owner of such Registrable Securities.

       b. Any notices, consents, waivers or other communications required or
       permitted to be given under the terms of this Agreement must be in
       writing and will be deemed to have been delivered:  (i) upon receipt,
       when delivered personally; (ii) upon receipt, when sent by facsimile

       generated and kept on file by the sending party); or (iii) one business

       c. Failure of any party to exercise any right or remedy under this
       Agreement or otherwise, or delay by a party in exercising such right

       laws of the State of New York, without giving effect to any choice of
       law or conflict of law provision or rule (whether of the State of New
       York or any other jurisdictions) that would cause the application of
       the laws of any jurisdictions other than the State of New York.  Each
       party hereby irrevocably submits to the non-exclusive jurisdiction of
       the state and federal courts sitting the City of New York, for the
       adjudication of any dispute hereunder or in connection herewith or
       with any transaction contemplated hereby or discussed herein, and
       hereby irrevocably waives, and agrees not to assert in any suit, action
       or proceeding, any claim that it is not personally subject to the
       jurisdiction of any such court, that such suit, action or proceeding is
       brought in an inconvenient forum or that the venue of such suit, action
       or proceeding is improper.  Each party hereby irrevocably waives
       personal service of process and consents to process being served in any
       such suit, action or proceeding by mailing a copy thereof to such party
       at the address for such 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.  If any provision of this Agreement shall be invalid or
       unenforceable in any jurisdiction, such invalidity or unenforceability
       shall not affect the validity or enforceability of the remainder of
       this Agreement in that jurisdiction or the validity or enforceability
       of any provision of this Agreement in any other jurisdiction.

       EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES
       NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE
       HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS AGREEMENT
       OR ANY TRANSACTION CONTEMPLATED HEREBY.

       e. This Agreement, the Exchange Agreement, the Convertible Notes, and
       the Security Agreement constitute the entire agreement among the
       parties hereto with respect to the subject matter hereof and thereof.
       There are no restrictions, promises, warranties or undertakings, other
       than those set forth or referred to herein and therein.  This Agreement,
       the Exchange Agreement, the Convertible Notes, and the Security
       Agreement supersede all prior agreements and understandings among the
       parties hereto with respect to the subject matter hereof and thereof.

       f. Subject to the requirements of Section 9, this Agreement shall inure
       to the benefit of and be binding upon the permitted successors and
       assigns of each of the parties hereto.

       g. The headings in this Agreement are for convenience of reference only
       and shall not limit or otherwise affect the meaning hereof.

       h. This Agreement may be executed in identical counterparts, each of
       which shall be deemed an original but all of which shall constitute one
       and the same agreement.  This Agreement, once executed by a party, may
       be delivered to the other party hereto by facsimile transmission of a
       copy of this Agreement bearing the signature of the party so delivering
       this Agreement.

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

       j. All consents and other determinations to be made by the Investors
       pursuant to this Agreement shall be made, unless otherwise specified in
       this Agreement, by Investors holding a majority of the Registrable
       Securities, determined as if all of the Convertible Notes, as
       applicable, then outstanding have been converted into or exercised for
       Registrable Securities without regard to any limitation on conversions
       of the Convertible Notes.

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

       l. This Agreement is intended for the benefit of the parties hereto and
       their respective permitted successors and assigns, and is not for the
       benefit of, nor may any provision hereof be enforced by, any other
       Person.

Attn:
Ladies and Gentlemen:

Re:     Ultradata Systems, Incorporated

    We are counsel to Ultradata Systems, Incorporated., a Delaware corporation
(the "Company"), which has entered into that certain Exchange Agreement (the
"Exchange Agreement") by and among the Company and the buyers named therein
(collectively, the "Holders") pursuant to which the Company issued to the
Holders its 11.25% Senior Subordinate Secured Convertible Promissory Notes
(the "Convertible Notes"), each convertible into shares of the Company's
common stock, $0.01 par value per share (the "Common Stock"), and Warrants
to purchase Common Stock.  Pursuant to the Exchange Agreement, the Company
also has entered into a Registration Rights Agreement with the Holders (the
"Registration Rights Agreement") pursuant to which the Company agreed, among
other things, to register the Registrable Securities (as defined in the
Registration Rights Agreement), including the shares of Common Stock issuable
upon conversion of the Preferred Shares or the Convertible Notes, under the
Securities Act of 1933, as amended (the "Securities Act").  In connection with
the Company's obligations under the Registration Rights Agreement, on ______ ,
2001, the Company filed a Registration Statement on Form S-3 (File No.
333-_______) (the "Registration Statement") with the Securities and Exchange
Commission (the "SEC") relating to the Registrable Securities which names
each of the Holders as a selling stockholder thereunder.



    In connection with the foregoing, we advise you that a member of the
SEC's staff has advised us by telephone that the SEC has entered an order
declaring the Registration Statement effective under the Securities Act at
[ENTER TIME OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have
no knowledge, after telephonic inquiry of a member of the SEC's staff, that
any stop order suspending its effectiveness has been issued or that any
proceedings for that purpose are pending before, or threatened by, the SEC
and the Registrable Securities are available for resale under the Securities
Act pursuant to the Registration Statement.

						Very truly yours,

SECURITY AGREEMENT

    This SECURITY AGREEMENT (the "Agreement") is made and entered into as of
August ____, 2001, by and among BH Capital Investments, L.P. for itself and in
trust, as agent for Excalibur Limited Partnership (together, "Secured Party"),
and Ultradata Systems, Incorporated, a Delaware corporation (the "Debtor").

RECITALS

    Pursuant to the terms of an Exchange Agreement, dated August ____, 2001
(the "Exchange Agreement"), the Debtor agreed to issue to the Secured Party
the Debtor's 11.25% Senior Subordinate Secured Convertible Promissory Notes
(collectively, the "Convertible Notes") in exchange for all shares of the
Debtor's Series A Convertible Preferred Stock held by the Secured Party.
Pursuant to the provisions of the Exchange Agreement and as a condition to
Secured Party's obligation to exchange shares of Series A Stock for the
Convertible Notes thereunder, the Debtor has agreed to provide certain
collateral to secure the Debtor's obligations to the Secured Party under the
Exchange Agreement and the Convertible Notes.

    NOW, THEREFORE, in consideration of the foregoing and of the covenants
set forth herein, the Secured Party and the Debtor hereby agree as follows:

ARTICLE I

    COLLATERAL

    As security for the Debtor's obligations under the Exchange Agreement, the
Convertible Notes, the Registration Rights Agreement and this Agreement, the
Debtor, hereby grants to the Secured Party a continuing security interest in
the property of the Debtor, listed and described in Schedule A attached
hereto (the "Collateral").   Concurrently with the execution and delivery of
this Agreement, the Debtor has executed and delivered Form UCC-1 Financing
Statements suitable for filing and/or recording with the appropriate filing
offices as requested by the Secured Party, which the Secured Party may file
at any time after the date hereof.  The grant of the security interest in the
Collateral under this Article I shall be effective as of the Issuance Date of
the Convertible Notes.


ARTICLE II

    OBLIGATIONS SECURED

    The Collateral and the power of collection pertaining thereto shall secure
the prompt and complete performance and payment of any and all obligations of
the Debtor to the Secured Party pursuant to this Agreement, the Exchange
Agreement,  the Registration Rights Agreement or the Convertible Notes, whether
arising prior to, on or after the issuance date of the Convertible Notes, and
specifically the unpaid Principal Amount outstanding at any time under the
Convertible Notes, plus all accrued and unpaid interest thereunder, together
with all fees, expenses, commissions, charges, penalties, and other amounts
owing by or chargeable to the Debtor under this Agreement, the Exchange
Agreement, the Registration Rights Agreement or the Convertible Notes, whether
any of the foregoing are direct or indirect, joint or several, absolute or
contingent, due or to become due, now existing or hereafter arising, no matter
how or when arising and whether under any present or future agreement or
instrument or otherwise, whether or not evidenced by a writing (collectively,
the "Obligations").

ARTICLE III

    DUTIES OF THE DEBTOR REGARDING COLLATERAL

    Section 3.1     Duties of the Debtor Regarding Collateral.  At all times
    hereafter, the Debtor shall:

    (a) preserve the Collateral in good condition and order and not permit it
    to be abused or misused;

    (b) not allow any of the Collateral to be affixed to real estate, except
    for any property deemed to be fixtures, provided such property is included
    in the Secured Party's security interest given hereunder;

    (c) maintain good and complete title to the Collateral subject to Permitted
    Liens;

    (d) keep the Collateral free and clear at all times of all other security
    interests, liens, or encumbrances of any kind, including, without limitation
    any lien arising as a result of the Debtor's failure to pay any and all
    taxes or governmental assessments or charges of any kind whatsoever, except
    for liens securing Senior Debt hereafter incurred as permitted under Section
    16 of the Convertible Notes and other Permitted Liens;

    (e) except as otherwise expressly provided herein, refrain from selling,
    assigning or otherwise disposing of any of the Collateral or moving or
    removing any of the Collateral except in the ordinary course of the Debtor's
    business, without the prior written consent of the Secured Party, or until
    all of the Debtor's obligations have been paid in full; provided, however,
    that Debtor shall have the right to sell its accounts to KBK Financial,
    Inc., a Delaware corporation, in accordance with the terms of an Account
    Transfer and Purchase Agreement, dated July 3, 2001, between the Company
    and KBK Financial, Inc., free and clear of the security interest granted
    under this Agreement;

    (f) promptly provide to the Secured Party such financial statements,
    reports, lists and schedules related to the Collateral and any other
    information relating to the Collateral as the Secured Party from time
    to time may reasonably request;

    (g) permit the Secured Party to inspect all books and records of the
    Debtor relating to the Collateral at such times, upon such notice and as
    often as the Secured Party may reasonably request; and

    (h) notify the Secured Party of any material change in any fact or
    circumstance warranted or represented by the Debtor herein or furnished
    in connection herewith to the Secured Party or if any Event of Default
    occurs.

    Anything in this Section 3.1 to the contrary notwithstanding, the Company
    shall have the right to sell its shares in Talon Research & Development
    Ltd., a New Zealand corporation, without the consent of the Secured
    Party, provided that upon receipt of the proceeds of such sale, the
    Company shall pay 50% of the proceeds of such sale (net of any amounts
    accrued for payment of taxes payable as a result of such sale in
    accordance with accounting principles generally accepted in the United
    States) to prepay the Principal Amount of the Note and accrued and unpaid
    interest thereon.  Anything in the Convertible Notes to the contrary
    notwithstanding, any such prepayment shall be applied to reduce the
    accrued and unpaid interest and then the Principal Amount of such
    Convertible Notes pro tanto without any prepayment premium.

    Section 3.2  "Permitted Liens"  means the following:

    (a) purchase money security interests in specific items of equipment;

    (b) leases of specific items of equipment, technology and intellectual
    property, including capital leases;

    (c) liens for taxes not yet payable;

    (d) security interests existing as of the date hereof and set forth on
    Schedule C, security interests hereafter created to secure Senior Debt as
    permitted by Section 16 of the Convertible Notes, and additional security
    interests and liens consented to in writing by Secured Party in its
    absolute discretion;

    (e) security interests being terminated substantially concurrently with

    of the indebtedness secured by liens of the type described above in clauses
    (a) or (b) above, provided that any extension, renewal or replacement lien

    amount of the indebtedness being extended, renewed or refinanced does not
    increase; or

    (h) liens in favor of customs and revenue authorities which secure payment
    of customs duties in connection with the importation of goods.

    Section 3.3  Consent to Additional Liens.  Secured Party will have the right
    to require, as a condition to any consent under clause (d) above, that the
    holder of the additional security interest or lien sign an intercreditor
    agreement on Secured Party's then standard form, acknowledge that the
    security interest is subordinate to the security interest in favor of
    Secured Party, and agree not to take any action to enforce its subordinate
    security interest so long as any Obligations remain outstanding, and that
    Debtor agrees that any uncured default in any obligation secured by the
    subordinate security interest shall also constitute an Event of Default
    under this Agreement.

ARTICLE IV

    EVENTS OF DEFAULT

    Section 4.1     Defined.  The occurrence of any of the following events
    shall constitute an event of default under this Agreement (each, an
    "Event of Default"):

    (i) the failure of the Debtor to perform or comply with any act, duty or
    obligation required to be performed under this Agreement if such failure
    is not remedied within ten (10) days following receipt by the Debtor of
    notice of such failure from the Secured Party; or

    (ii) if any of the representations or warranties of the Debtor set forth
    in this Agreement shall prove to have been incorrect in any material
    respect when made, or if they become incorrect, if not cured within thirty
    (30) days of notice from Secured Party of such event; or

    (iii)  if any material portion of the Collateral shall be damaged, destroyed
    or otherwise lost and such damage, destruction or loss is not covered by
    insurance; or

    (iv) if an Event of Default as defined in the Convertible Notes shall have
    occurred; or

    (v)  if Monte Ross is terminated as Chairman of the Debtor (including a
    change or diminution of his duties as such), whether by resignation,
    termination, death, disability or otherwise, unless the Secured Party
    shall have consented to such termination, except for a termination in
    connection with a Change of Control (as defined in the Convertible Note).

    Section 4.2   Rights and Remedies Upon Default.  If an Event of Default
    shall have occurred and be continuing hereunder or under the Convertible
    Notes, the Secured Party may, at its sole option, without notice or demand,
    declare the Obligations to be immediately due and payable.  As to any
    Collateral, the Secured Party shall have the rights and remedies of any
    secured creditor under the Uniform Commercial Code as in effect, from time
    to time, in Missouri ("UCC"), such rights to be exercised in such order or
    manner as the Secured Party may determine in its sole discretion against
    the Debtor.  If for any reason the Secured Party should be required by law
    or otherwise to give notice to the Debtor of the sale of any Collateral,
    the Debtor agrees that any written notice sent by overnight delivery service
    not less than five (5) calendar days before the sale or mailed postage
    prepaid to the Debtor's address listed below not less than ten (10) calendar
    days before the sale shall be deemed reasonable and adequate.

    collection of any sums due the Debtor arising from or in connection with

    accounts, relating howsoever to this Agreement or the Convertible Notes,

    its books, records, documents and instruments relating to the Collateral
    in such manner as the Secured Party may require;

    (d) mark or stamp all invoices with a similar legend satisfactory to the
    Secured Party so as to indicate that the same must be now paid directly to
    the Secured Party;

    hereunder or as defined in the Convertible Notes, directly to notify any

    directly to the Secured Party, and the Secured Party shall have the further

    transactions which have been approved by Secured Party.

     require the Secured Party to (a) proceed against any person,  (b) proceed

     Section 8.2   Waiver of Defense.  The Debtor waives any defense that it

     true attorney-in-fact to perform any of the following powers, which are
     irrevocable until termination of this Agreement and may be exercised, from
     time to time, by the Secured Party's officers and employees or any of them
     in the event of a default hereunder or under the Convertible Notes or
     either of them:  (i) to perform any obligation of the Debtor hereunder in
     the Debtor's name or otherwise; (ii) to collect by legal proceedings or
     otherwise all dividends, interest, principal or other sums now or hereafter
     payable upon or on account of the Collateral, to accept other property in
     exchange for the Collateral, and any money or property received in exchange
     for the Collateral may be applied to the Obligations to the Secured Party
     or held by the Secured Party under this Agreement; (iii) to make any
     compromise or settlement the Secured Party deems desirable or proper in
     respect of the Collateral; (iv) to insure, process and preserve the
     Collateral.  The foregoing power of attorney shall take effect only upon

     naming Debtor as the debtor thereunder without the signature of Debtor in
     such jurisdictions as shall be necessary to perfect Secured Party's
     security interest as contemplated by the Agreement.  The power-of-attorney
     granted hereunder shall be deemed to be the authorization required under
     Section 9-509 of the UCC to file such Financing Statements without Debtor's
     signature.

     Section 9.2  Cross Default.  Debtor agrees and acknowledges that default
     under the terms of this Agreement shall constitute default under the

     default under this Agreement.  The security interests, liens and other
     rights and interests in and relative to any of the real or personal
     property of the Debtor now or hereafter granted to the Secured Party by
     the Debtor by or in any instrument or agreement, including but not limited
     to this Agreement, the Exchange Agreement, the  Registration Rights
     Agreement or the Convertible Notes shall serve as security for any and
     all liabilities of the Debtor to the Secured Party, including but not
     limited to the liabilities described in this Agreement, the Exchange
     Agreement, the Registration Rights Agreement and the Convertible Notes,
     and, for the repayment thereof, the Secured Party may resort to any
     security held by it in such order and manner as it may elect.

     Section 9.3  Notices.  All notices, requests or demand to or upon a party
     to this Agreement shall be given or made by the other party hereto in

    limiting any of the terms of the Exchange Agreement, the Registration
    Rights Agreement or the Convertible Notes, the Debtor shall pay all
    reasonable fees, costs, and expenses (including without limitation
    reasonable attorneys' fees and legal expenses) incurred by the Secured
    Party in connection with (a) filing or recording any documents (including
    all taxes in connection therewith) in public offices; and (b) paying or
    discharging any taxes, counsel fees, maintenance fees, encumbrances, or
    other amounts in connection with protecting, maintaining, or preserving
    the Collateral or defending or prosecuting any actions or proceedings
    arising out of or related to the Collateral.

    Section 9.5  No Waiver.  No course of dealing between the Debtor and the
    Secured Party, nor any failure to exercise nor any delay in exercising,
    on the part of the  Secured Party, any right, power, or privilege under
    this Agreement or under the Exchange Agreement, the Registration Rights
    Agreement or the Convertible Notes, or any other agreement, shall operate
    as a waiver.  No single or partial exercise of any right, power, or
    privilege under this Agreement or under the Purchase Agreement or any
    other agreement by the Secured Party shall preclude any other or further
    exercise of such right, power, or privilege or the exercise of any other
    right, power, or privilege by the Secured Party.

    Section 9.6  Rights Are Cumulative.  All of the Secured Party's rights and
    remedies with respect to the Collateral whether established by this
    Agreement, the Exchange Agreement, the Convertible Notes or any other
    documents or agreements, or by law shall be cumulative and may be exercised
    concurrently or in any order.

    Section 9.7  Indemnity.  The Debtor shall protect, defend, indemnify, and
    hold harmless the Secured Party and the Secured Party's assigns from all
    liabilities, losses, and costs (including without limitation reasonable

    relating to the matters in this Agreement, including, without limitation,
    in connection with the Secured Party's defense of any action brought by a
    third party against the Secured Party relating to this Agreement or any of
    the Collateral, but otherwise not arising from the Secured Party's gross
    negligence or willful misconduct.

    Section 9.8  Severability.  The provisions of this Agreement are severable.
    If any provision of this Agreement is held invalid or unenforceable in
    whole or in part in any jurisdiction, then such invalidity or
    unenforceability shall affect only such provision, or part thereof, in
    such jurisdiction, and shall not in any manner affect such provision or
    part thereof in any other jurisdiction, or any other provision of this
    Agreement in any jurisdiction.

    Section 9.9  Amendments; Entire Agreement.  This Agreement is subject to
    modification only by a writing signed by the parties. To the extent that
    any provision of this Agreement conflicts with any provision of the Exchange
    Agreement, the Registration Rights Agreement or the Convertible Notes, the
    provision giving the Secured Party greater rights or remedies shall govern,
    it being understood that the purpose of this Agreement is to add to, and
    not detract from, the rights granted to Secured Party under the Exchange
    Agreement, the Registration Rights Agreement and the Convertible Notes.
    This Agreement, the Exchange Agreement, the Registration Rights Agreement,
    the Convertible Notes and the documents relating thereto comprise the
    entire agreement of the parties with respect to the matters addressed in
    this Agreement.

    Section 9.10  Further Assurances.  At the Secured Party's request, Debtor
    shall execute and deliver to the Secured Party any further instruments or
    documentation, and perform any acts, that may be reasonably necessary or
    appropriate to implement this Agreement, the Exchange  Agreement, the
    Registration Rights Agreement, or the Convertible Notes or any other
    agreement, and the documents relating thereto, including without limitation
    any instrument or documentation reasonably necessary or appropriate to
    create, maintain, perfect, or effectuate the Secured Party's security
    interests in the Collateral.

    Section 9.11  Release.  At such time as the Debtor shall completely satisfy
    all of the Obligations and no Convertible Notes are outstanding, the
    Secured Party shall execute and deliver to the Debtor all assignments and
    other instruments as may be reasonably necessary or proper to terminate
    this Agreement and the Secured Party's security interest in the Collateral,
    subject to any disposition of the Collateral which may have been made by
    the Secured Party pursuant to this Agreement.  For the purpose of this
    Agreement, the Obligations shall be deemed to continue if the Debtor enters
    into any bankruptcy or similar proceeding at a time when any amount paid
    to the Secured Party could be ordered to be repaid as a preference or
    pursuant to a similar theory, and shall continue until it is finally
    determined that no such repayment can be ordered.

    Section 9.12  Successors.  The benefits and burdens of this Agreement
    shall inure to the benefit of and be binding upon the respective
    successors and permitted assigns of the parties; provided, however, that
    the Debtor may not transfer any of the Collateral or any rights hereunder,
    without the prior written consent of the Secured Party, except as
    specifically permitted hereby.

    Section 9.13  Governing Law.  THE VALIDITY, INTERPRETATION AND ENFORCEMENT
    OF THIS AGREEMENT AND ANY DISPUTE ARISING OUT OF OR IN CONNECTION WITH
    THIS AGREEMENT, WHETHER SOUNDING IN CONTRACT, TORT, EQUITY OR OTHERWISE,
    SHALL BE GOVERNED BY THE INTERNAL LAWS AND DECISIONS OF THE STATE OF
    MISSOURI.  ALL DISPUTES BETWEEN THE DEBTOR AND SECURED PARTY, WHETHER
    SOUNDING IN CONTRACT, TORT, EQUITY OR OTHERWISE, SHALL BE RESOLVED ONLY
    BY STATE AND FEDERAL COURTS LOCATED IN ST. LOUIS COUNTY, MISSOURI AND THE

    SECURED PARTY SHALL HAVE THE RIGHT, TO THE EXTENT PERMITTED BY APPLICABLE
    LAW, TO PROCEED AGAINST THE DEBTOR OR ITS PROPERTY IN ANY LOCATION
    REASONABLY SELECTED BY SECURED PARTY IN GOOD FAITH TO ENABLE SECURED PARTY
    TO REALIZE ON SUCH PROPERTY, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER
    IN FAVOR OF SECURED PARTY.  THE DEBTOR AGREES THAT IT WILL NOT ASSERT ANY
    PERMISSIVE COUNTERCLAIMS, SETOFFS OR CROSS-CLAIMS IN ANY PROCEEDING
    BROUGHT BY SECURED PARTY.  THE DEBTOR WAIVES ANY OBJECTION THAT IT MAY
    HAVE TO THE LOCATION OF THE COURT IN WHICH SECURED PARTY HAS COMMENCED A
    PROCEEDING, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF
    VENUE OR BASED ON FORUM NON CONVENES.

    Section 9.14  Waiver of Right to Jury Trial.  THE SECURED PARTY AND THE
    DEBTOR EACH HEREBY WAIVE THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR
    PROCEEDING BASED UPON, ARISING OUT OF, OR IN ANY WAY RELATING TO:

    CASES, WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE.
