         Each Buyer represents and warrants, severally and not jointly, that:

                                      -2-
<PAGE>

                  (a) INVESTMENT PURPOSE. Each Buyer is acquiring the Securities
for its own account for investment only and not with a view towards, or for
resale in connection with, the public sale or distribution thereof, except
pursuant to sales registered or exempted under the Securities Act; provided,
however, that by making the representations herein, such Buyer reserves the
right to dispose of the Securities at any time in accordance with or pursuant to
an effective registration statement covering such Securities or an available
exemption under the Securities Act. Such Buyer does not presently have any
agreement or understanding, directly or indirectly, with any Person to
distribute any of the Securities.

                  (b) ACCREDITED INVESTOR STATUS. Each Buyer is an "ACCREDITED
INVESTOR" as that term is defined in Rule 501(a)(3) of Regulation D.

                  (c) RELIANCE ON EXEMPTIONS. Each Buyer understands that the
Securities are being offered and sold to it in reliance on specific exemptions
from the registration requirements of United States federal and state securities
laws and that the Company is relying in part upon the truth and accuracy of, and
such Buyer's compliance with, the representations, warranties, agreements,
acknowledgments and understandings of such Buyer set forth herein in order to
determine the availability of such exemptions and the eligibility of such Buyer
to acquire the Securities.

                  (d) INFORMATION. Each Buyer and its advisors (and his or, its
counsel), if any, have been furnished with all materials relating to the
business, finances and operations of the Company and information he deemed
material to making an informed investment decision regarding his purchase of the
Securities, which have been requested by such Buyer. Each Buyer and its
advisors, if any, have been afforded the opportunity to ask questions of the
Company and its management. Neither such inquiries nor any other due diligence
investigations conducted by such Buyer or its advisors, if any, or its
representatives shall modify, amend or affect such Buyer's right to rely on the
Company's representations and warranties contained in Section 3 below. Each
Buyer understands that its investment in the Securities involves a high degree
of risk. Each Buyer is in a position regarding the Company, which, based upon
employment, family relationship or economic bargaining power, enabled and
enables such Buyer to obtain information from the Company in order to evaluate
the merits and risks of this investment. Each Buyer has sought such accounting,
legal and tax advice, as it has considered necessary to make an informed
investment decision with respect to its acquisition of the Securities.

                  (e) NO GOVERNMENTAL REVIEW. Each Buyer understands that no
United States federal or state agency or any other government or governmental
agency has passed on or made any recommendation or endorsement of the
Securities, or the fairness or suitability of the investment in the Securities,
nor have such authorities passed upon or endorsed the merits of the offering of
the Securities. Each Buyer understands and acknowledges that the Company has
undertaken and will undertake no efforts to comply with any laws of any
jurisdiction outside the United States relating to the issuance and sale of its
securities except as may be provided herein.

                  (f) TRANSFER OR RESALE. Each Buyer understands that: (i) the
Securities have not been and are not being registered under the Securities Act
or any state securities laws, and may not be offered for sale, sold, assigned or
transferred unless (A) subsequently registered thereunder, (B) such Buyer shall
have delivered to the Company an opinion of counsel, in a generally acceptable
form, to the effect that such Securities to be sold, assigned or transferred may

                                      -3-
<PAGE>

be sold, assigned or transferred pursuant to an exemption from such registration
requirements, or (C) such Buyer provides the Company with reasonable assurances
(in the form of seller and broker representation letters) that such Securities
can be sold, assigned or transferred pursuant to Rule 144, Rule 144(k), or Rule
144A promulgated under the Securities Act, as amended (or a successor rule
thereto) (collectively, "RULE 144"), in each case following the applicable
holding period set forth therein; (ii) any sale of the Securities made in
reliance on Rule 144 may be made only in accordance with the terms of Rule 144
and further, if Rule 144 is not applicable, any resale of the Securities under
circumstances in which the seller (or the person through whom the sale is made)
may be deemed to be an underwriter (as that term is defined in the Securities
Act) may require compliance with some other exemption under the Securities Act
or the rules and regulations of the SEC thereunder; and (iii) neither the
Company nor any other person is under any obligation to register the Securities
under the Securities Act or any state securities laws or to comply with the
terms and conditions of any exemption thereunder. The Company reserves the right
to place stop transfer instructions against the shares and certificates for the
Conversion Shares.

                  (g) LEGENDS. Each Buyer agrees to the imprinting, so long as
is required by this Section 2(g), of a restrictive legend in substantially the
following form (and a stop transfer order may be placed against transfer of such
stock certificates):

                  THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
                  APPLICABLE STATE SECURITIES LAWS. THE SECURITIES HAVE BEEN
                  ACQUIRED SOLELY FOR INVESTMENT PURPOSES AND NOT WITH A VIEW
                  TOWARD RESALE AND MAY NOT BE OFFERED FOR SALE, SOLD,
                  TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE
                  REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES
                  ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS,
                  OR AN OPINION OF COUNSEL, IN A GENERALLY ACCEPTABLE FORM, THAT
                  REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR APPLICABLE
                  STATE SECURITIES LAWS.

Certificates evidencing the Conversion Shares or Warrant Shares shall not
contain any legend (including the legend set forth above), (i) while a
registration statement (including the Registration Statement) covering the
resale of such security is effective under the Securities Act, (ii) following
any sale of such Conversion Shares or Warrant Shares pursuant to Rule 144, (iii)
if such Conversion Shares or Warrant Shares are eligible for sale under Rule
144(k), or (iv) if such legend is not required under applicable requirements of
the Securities Act (including judicial interpretations and pronouncements issued
by the staff of the SEC). The Company shall cause its counsel to issue a legal
opinion to the Company's transfer agent promptly after the effective date (the
"EFFECTIVE DATE") of a Registration Statement if required by the Company's
transfer agent to effect the removal of the legend hereunder. If all or any
portion of the Convertible Debentures or Warrants are exercised by a Buyer that
is not an Affiliate (as defined below) of the Company (a "NON-AFFILIATED BUYER")
at a time when there is an effective registration statement to cover the resale

                                      -4-
<PAGE>

of the Conversion Shares or the Warrant Shares, such Conversion Shares or
Warrant Shares shall be issued free of all legends. The Company agrees that
following the Effective Date or at such time as such legend is no longer
required under this Section 2(g), it will, no later than three (3) Trading Days
following the delivery by a Non-Affiliated Buyer to the Company or the Company's
transfer agent of a certificate representing Conversion Shares or Warrant
Shares, as the case may be, issued with a restrictive legend (such third Trading
Day, the "LEGEND REMOVAL DATE"), deliver or cause to be delivered to such
Non-Affiliated Buyer a certificate representing such shares that is free from
all restrictive and other legends. The Company may not make any notation on its
records or give instructions to any transfer agent of the Company that enlarge
the restrictions on transfer set forth in this Section. Each Buyer acknowledges
that the Company's agreement hereunder to remove all legends from Conversion
Shares or Warrant Shares is not an affirmative statement or representation that
such Conversion Shares or Warrant Shares are freely tradable. Each Buyer,
severally and not jointly with the other Buyers, agrees that the removal of the
restrictive legend from certificates representing Securities as set forth in
this Section 3(g) is predicated upon the Company's reliance that the Buyer will
sell any Securities pursuant to either the registration requirements of the
Securities Act, including any applicable prospectus delivery requirements, or an
exemption therefrom, and that if Securities are sold pursuant to a Registration
Statement, they will be sold in compliance with the plan of distribution set
forth therein.

                  (h) AUTHORIZATION, ENFORCEMENT. This Agreement, and all
related agreements, are within Buyer's corporate power and have been duly and
validly authorized, executed and delivered on behalf of such Buyer and are valid
and binding agreements of such Buyer enforceable in accordance with their terms,
except as such enforceability may be limited by general principles of equity or
applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and
other similar laws relating to, or affecting generally, the enforcement of
applicable creditors' rights and remedies.

                  (i) RECEIPT OF DOCUMENTS. Each Buyer and his or its counsel
has received and read in their entirety: (i) this Agreement and each
representation, warranty and covenant set forth herein and the Transaction
Documents (as defined herein); (ii) all due diligence and other information
necessary to verify the accuracy and completeness of such representations,
warranties and covenants; (iii) the Company's Form 10-KSB for the fiscal year
ended December 31, 2006; (iv) the Company's Form 8-Ks filed with the SEC on
January 4, 2007, January 24, 2007, April 4, 2007; May 11, 2007 and June 21,
2007; and (vi) answers to all questions each Buyer submitted to the Company
regarding an investment in the Company; and each Buyer has relied on the
information contained therein and has not been furnished any other documents,
literature, memorandum or prospectus. Buyer acknowledges and agrees that the
Company's representations and warranties are limited to exclusively those
expressly stated in this Agreement and exclude any and all statements made in
any other business plan, prospectus, projections, memorandum or other document
or in any oral communication.

                  (j) DUE FORMATION OF CORPORATE AND OTHER BUYERS. If the
Buyer(s) is a corporation, trust, partnership or other entity that is not an
individual person, it has been formed and validly exists and has not been
organized for the specific purpose of purchasing the Securities and is not
prohibited from doing so.

                                      -5-
<PAGE>

                  (k) NO LEGAL ADVICE FROM THE COMPANY. Each Buyer acknowledges,
that it had the opportunity to review this Agreement and the transactions
contemplated by this Agreement with his or its own legal counsel and investment
and tax advisors. Each Buyer is relying solely on such counsel and advisors and
not on any statements or representations of the Company or any of its
representatives or agents for legal, tax or investment advice with respect to
this investment, the transactions contemplated by this Agreement or the
securities laws of any jurisdiction.

         3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         Except as set forth in the SEC Documents (as defined herein) or under
the corresponding section of the Disclosure Schedules which Disclosure Schedules
shall be deemed a part hereof and to qualify any representation or warranty
otherwise made herein to the extent of such disclosure, the Company hereby makes
the representations and warranties set forth below to each Buyer:

                  (a) ORGANIZATION AND QUALIFICATION. The Company and its
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 to own their properties and to carry on their
business as now being conducted. Each of the Company and its subsidiaries is
duly qualified as a foreign corporation to do business and is in good standing
in every jurisdiction in which the nature of the business conducted by it makes
such qualification necessary, except to the extent that the failure to be so
qualified or be in good standing would not have or reasonably be expected to
result in (i) a material adverse effect on the legality, validity or
enforceability of any Transaction Document, (ii) a material adverse effect on
the results of operations, assets, business or condition (financial or
otherwise) of the Company, taken as a whole, or (iii) a material adverse effect
on the Company's ability to perform in any material respect on a timely basis
its obligations under any Transaction Document (any of (i), (ii) or (iii), a
"MATERIAL ADVERSE EFFECT") and no proceeding has been instituted in any such
jurisdiction revoking, limiting or curtailing or seeking to revoke, limit or
curtail such power and authority or qualification.

                  (b) AUTHORIZATION, ENFORCEMENT, COMPLIANCE WITH OTHER
INSTRUMENTS. (i) The Company has the requisite corporate power and authority to
enter into and perform its obligations under this Agreement, the Convertible
Debentures, the Warrants, the Security Agreement, the Irrevocable Transfer Agent
Instructions, and each of the other agreements entered into by the parties
hereto in connection with the transactions contemplated by this Agreement
(collectively the "TRANSACTION DOCUMENTS") and to issue the Securities in
accordance with the terms hereof and thereof, (ii) the execution and delivery of
the Transaction Documents by the Company and the consummation by it of the
transactions contemplated hereby and thereby, including, without limitation, the
issuance of the Securities, the reservation for issuance and the issuance of the
Conversion Shares, and the reservation for issuance and the issuance of the
Warrant Shares, have been duly authorized by the Company's Board of Directors
and no further consent or authorization is required by the Company, its Board of
Directors or its stockholders, (iii) the Transaction Documents have been duly
executed and delivered by the Company, (iv) the Transaction Documents constitute
the valid and binding obligations of the Company enforceable against the Company
in accordance with their terms, except as such enforceability may be limited by

                                      -6-
<PAGE>

general principles of equity or applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation or similar laws relating to, or
affecting generally, the enforcement of creditors' rights and remedies. The
authorized officer of the Company executing the Transaction Documents knows of
no reason why the Company cannot file the Registration Statement as required
under the Registration Rights Agreement or perform any of the Company's other
obligations under the Transaction Documents.

                  (c) CAPITALIZATION. The authorized capital stock of the
Company consists of 95,000,000 shares of Common Stock and 5,000,000 shares of
Preferred Stock, par value $0.001 ("PREFERRED STOCK") of which 36,641,779 shares
of Common Stock and no shares of Preferred Stock are issued and outstanding. All
of the outstanding shares of capital stock of the Company are validly issued,
fully paid and nonassessable, have been issued in compliance with all federal
and state securities laws, and none of such outstanding shares was issued in
violation of any preemptive rights or similar rights to subscribe for or
purchase securities. Except as disclosed in the SEC Documents or Schedule 3(d)
and immediately preceding the Closing: (i) none of the Company's capital stock
is subject to preemptive rights or any other similar rights or any liens or
encumbrances suffered or permitted by the Company; (ii) there are no outstanding
options, warrants, scrip, rights to subscribe to, calls or commitments of any
character whatsoever relating to, or securities or rights convertible into, or
exercisable or exchangeable for, any capital stock of the Company or any of its
subsidiaries, or contracts, commitments, understandings or arrangements by which
the Company or any of its subsidiaries is or may become bound to issue
additional capital stock of the Company or any of its subsidiaries or options,
warrants, scrip, rights to subscribe to, calls or commitments of any character
whatsoever relating to, or securities or rights convertible into, or exercisable
or exchangeable for, any capital stock of the Company or any of its
subsidiaries; (iii) there are no outstanding debt securities, notes, credit
agreements, credit facilities or other agreements, documents or instruments
evidencing indebtedness of the Company or any of its subsidiaries or by which
the Company or any of its subsidiaries is or may become bound; (iv) there are no
financing statements securing obligations in any material amounts, either singly
or in the aggregate, filed in connection with the Company or any of its
subsidiaries; (v) there are no outstanding securities or instruments of the
Company or any of its subsidiaries which contain any redemption or similar
provisions, and there are no contracts, commitments, understandings or
arrangements by which the Company or any of its subsidiaries is or may become
bound to redeem a security of the Company or any of its subsidiaries; (vi) there
are no securities or instruments containing anti-dilution or similar provisions
that will be triggered by the issuance of the Securities; (vii) the Company does
not have any stock appreciation rights or "phantom stock" plans or agreements or
any similar plan or agreement; and (viii) the Company and its subsidiaries have
no liabilities or obligations required to be disclosed in the SEC Documents but
not so disclosed in the SEC Documents, other than those incurred in the ordinary
course of the Company's or its subsidiaries' respective businesses and which,
individually or in the aggregate, do not or would not have a Material Adverse
Effect. The Company has furnished to the Buyers or made available through the
SEC Documents true, correct and complete copies of the Company's Certificate of
Incorporation, as amended and as in effect on the date hereof (the "CERTIFICATE
OF INCORPORATION"), and the Company's Bylaws, as amended and as in effect on the
date hereof (the "BYLAWS"), and the terms of all securities convertible into, or
exercisable or exchangeable for, shares of Common Stock and the material rights
of the holders thereof in respect thereto. No further approval or authorization
of any stockholder, the Board of Directors of the Company or others is required

                                      -7-
<PAGE>

for the issuance and sale of the Securities. There are no stockholders
agreements, voting agreements or other similar agreements with respect to the
Company's capital stock to which the Company is a party or, to the knowledge of
the Company, between or among any of the Company's stockholders.

                  (d) ISSUANCE OF SECURITIES. The issuance of the Convertible
Debentures and the Warrants is duly authorized and free from all taxes, liens
and charges with respect to the issue thereof. Upon conversion in accordance
with the terms of the Convertible Debentures or exercise in accordance with the
Warrants, as the case may be, the Conversion Shares and Warrant Shares,
respectively, when issued will be validly issued, fully paid and nonassessable,
free from all taxes, liens and charges with respect to the issue thereof. The
Company has reserved from its duly authorized capital stock the appropriate
number of shares of Common Stock as set forth in this Agreement.

                  (e) NO CONFLICTS. The execution, delivery and performance of
the Transaction Documents by the Company and the consummation by the Company of
the transactions contemplated hereby and thereby (including, without limitation,
the issuance of the Convertible Debentures and the Warrants, and reservation for
issuance and issuance of the Conversion Shares and the Warrant Shares) will not
(i) result in a violation of any certificate of incorporation, certificate of
formation, any certificate of designations or other constituent documents of the
Company, any capital stock of the Company or bylaws of the Company or (ii)
conflict with, or constitute a material default (or an event which with notice
or lapse of time or both would become a material default) in any respect under,
or give to others any rights of termination, amendment, acceleration or
cancellation of, any agreement, indenture or instrument to which the Company is
a party, or (iii) result in a violation of any law, rule, regulation, order,
judgment or decree (including foreign, federal and state securities laws and
regulations and the rules and regulations of the National Association of
Securities Dealers Inc.'s OTC Bulletin Board) applicable to the Company or by
which any property or asset of the Company is bound or affected; except in the
case of each of clauses (ii) and (iii), such as could not, individually or in
the aggregate, have or reasonably be expected to result in a Material Adverse
Effect. The business of the Company is not being conducted, and shall not be
conducted in violation of any material law, ordinance, or regulation of any
governmental entity. Except as specifically contemplated by this Agreement and
as required under the Securities Act and any applicable state securities laws,
the Company is not required to obtain any consent, authorization or order of, or
make any filing or registration with, any court or governmental agency in order
for it to execute, deliver or perform any of its obligations under or
contemplated by this Agreement or the Registration Rights Agreement 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. The Company is unaware of any facts or circumstance, which
might give rise to any of the foregoing.

                  (f) SEC DOCUMENTS; FINANCIAL STATEMENTS. The Company has filed
all reports, schedules, forms, statements and other documents required to be
filed by it with the SEC under the Securities Exchange Act of 1934, as amended
(the "EXCHANGE ACT"), for the two years preceding the date hereof (or such
shorter period as the Company was required by law or regulation to file such
material) (all of the foregoing filed prior to the date hereof or amended after
the date hereof and all exhibits included therein and financial statements and
schedules thereto and any prospectuses that are current as of the date hereof
and documents incorporated by reference therein, being hereinafter referred to

                                      -8-
<PAGE>

as the "SEC DOCUMENTS") on timely basis or has received a valid extension of
such time of filing and has filed any such SEC Document prior to the expiration
of any such extension. The Company has delivered to the Buyers or their
representatives, or made available through the SEC's website at
http://www.sec.gov., true and complete copies of the SEC Documents. As of their
respective dates, the SEC Documents complied in all material respects with the
requirements of the Exchange Act and the rules and regulations of the SEC
promulgated thereunder applicable to the SEC Documents, and none of the SEC
Documents, at the time they were filed with the SEC, contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading. As of
their respective dates, the financial statements of the Company included in the
SEC Documents complied as to form in all material respects with applicable
accounting requirements and the published rules and regulations of the SEC with
respect thereto. Such financial statements have been prepared in accordance with
generally accepted accounting principles, consistently applied, during the
periods involved (except (i) as may be otherwise indicated in such financial
statements or the notes thereto, or (ii) in the case of unaudited interim
statements, to the extent they may exclude footnotes or may be condensed or
summary statements) and fairly present in all material respects the financial
position of the Company as of the dates thereof and the results of its
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end audit adjustments). No other
information provided by or on behalf of the Company to the Buyers which is not
included in the SEC Documents, including, without limitation, information
referred to in Section 2(i) 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 and not misleading.

                  (g) 10(B)-5. The SEC Documents do not include any untrue
statements of material fact, nor do they omit to state any material fact

transactions contemplated by this Agreement) (collectively, the "BUYER
INDEMNITEES") from and against any and all actions, causes of action, suits,
claims, losses, costs, penalties, fees, liabilities and damages, and expenses in
connection therewith (irrespective of whether any such Buyer Indemnitee is a

Debentures in the Company. To the extent that the foregoing undertaking by the
Company may be unenforceable for any reason, the Company shall make the maximum
contribution to the payment and satisfaction of each of the Indemnified
Liabilities, which is permissible under applicable law. This indemnification
shall not apply to any Indemnified Liabilities arising out of the willful or
reckless actions or inactions of any Buyer Indemnitee.

contemplated by this Agreement) (collectively, the "COMPANY INDEMNITEES") from
and against any and all Indemnified Liabilities incurred by the Indemnitees or
any of them as a result of, or arising out of, or relating to (a) any
misrepresentation or breach of any representation or warranty made by the
Buyer(s) in this Agreement, the Transaction Documents or any other certificate,

Liabilities arising out of the willful or reckless actions or inactions of any
Company Indemnitee.

                  (a) The Company does hereby, on behalf of itself and its
agents, representatives, attorneys, assigns, heirs, executors and administrators
(collectively, "Company Parties") RELEASE AND FOREVER DISCHARGE the Buyer and
its subsidiaries and its respective affiliates, parents, joint ventures,
officers, directors, shareholders, interest holders, members, managers,

executors and administrators (collectively, "Buyer Parties") from all causes of
action, suits, debts, claims and demands whatsoever known or unknown, at law, in
equity or otherwise, which the Company Parties ever had, now has, or hereafter

debtor of the Buyer on or prior to the date hereof (including, without
limitation, under the Prior Debentures, the YA Bridge Debentures, and the
documents entered into in connection therewith), any agreement between the
Company Parties and the Buyer Parties entered into prior to the date hereof, any
claims for reasonable attorneys' fees and costs, and including, without
limitation, any claims relating to fees, penalties, liquidated damages, and
indemnification for losses, liabilities and expenses. The release contained in
this Section 9 is effective without regard to the legal nature of the claims
raised and without regard to whether any such claims are based upon tort,
equity, or implied or express contract. It is expressly understood and agreed
that this release shall operate as a clear and unequivocal waiver by the Company
Parties of any such claim whatsoever.

(b) The Company acknowledges that there is a risk that after signing this
Agreement it may discover losses or claims that are released under this
Agreement, but that are presently unknown to it. The Company assumes this risk
                  and understands that this release shall apply to any such
losses and claims. The
Company understands that this Agreement includes a full and final release
covering all known and unknown, suspected or unsuspected injuries, debts, claims
or damages which have arisen or may have arisen from any matters, acts,
omissions or dealings released in Section 9(a) above.

                  (c) The Company covenants and agrees that all amounts owed,
together with interest accrued and accruing thereon, and any applicable
redemption premiums now or hereafter payable by the Company to the Buyer in
connection with the Prior Debentures, the YA Bridge Debentures, and all
documents and agreements entered into in connection therewith, are
unconditionally owing by the Company to the Buyer, without offset, setoff,
defense or counterclaim of any kind, nature or description whatsoever.

                  (d) From and after the date hereof, notwithstanding any prior
agreements between the Company and the Buyer (whether written, oral, or
otherwise), and except as set forth in the Amendment to the Prior Debentures and
the Bridge Loans entered into on the date hereof, any and all prior conversion
limitations, lockup agreement of the Buyer, or restrictions of the Buyer
regarding the sale of the Common Stock of the Company shall be null and void.

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

                  (e) ENTIRE AGREEMENT, AMENDMENTS. This Agreement supersedes
all other prior oral or written agreements between the Buyer(s), the Company,
their affiliates and persons acting on their behalf with respect to the matters

                  (g) SUCCESSORS AND ASSIGNS. This Agreement shall be binding
upon and inure to the benefit of the parties and their respective successors and
assigns. Neither the Company nor any Buyer shall assign this Agreement or any

and assigns, and is not for the benefit of, nor may any provision hereof be
enforced by, any other person.

                  (i) SURVIVAL. Unless this Agreement is terminated under
Section 9(l), the representations and warranties of the Company and the Buyer
contained herein, the agreements and covenants contained herein, and the
indemnification provisions set forth in Section 8, shall survive the Closing for
a period of two (2) years following the date on which the all amounts owed to
the Buyer pursuant to the Prior Debentures and the Bridge Loans are paid in
full. The Buyer shall be responsible only for its own representations,
warranties, agreements and covenants hereunder.

                  (j) PUBLICITY. The Company and the Buyer(s) shall have the
right to approve, before issuance any press release or any other public
statement with respect to the transactions contemplated hereby made by any
party; provided, however, that the Company shall be entitled, without the prior
approval of the Buyer(s), to issue any press release or other public disclosure
with respect to such transactions required under applicable securities or other
laws or regulations (the Company shall use its best efforts to consult the
Buyer(s) in connection with any such press release or other public disclosure
prior to its release and Buyer(s) shall be provided with a copy thereof upon
release thereof).

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

                  (l) TERMINATION. In the event that the First Closing shall not
have occurred with respect to the Buyers on or before five (5) business days
from the date hereof due to the Company's or the Buyer's failure to satisfy the
conditions set forth in Sections 6 and 7 above (and the non-breaching party's
failure to waive such unsatisfied condition(s)), the non-breaching party shall
have the option to terminate this Agreement with respect to such breaching party

                                      -23-
<PAGE>

at the close of business on such date without liability of any party to any
other party; provided, however, that if this Agreement is terminated by the
Company pursuant to this Section 9(l), the Company shall remain obligated to
reimburse the Buyer(s) for the fees and expenses of Yorkville Advisors LLC
described in Section 4(g) above.

                  (m) BROKERAGE. The Company represents that no broker, agent,
finder or other party, including officers, directors, employees, or affiliates
of the Company (collectively, "BROKER") has been retained by it in connection
with the transactions contemplated hereby and that no fee or commission (in any
form, whether cash, notes, stock, warrants, or convertible securities) has been
agreed by the Company, or will be paid by the Company to any Broker for or on
account of the transactions contemplated hereby.

                  (n) NO STRICT CONSTRUCTION. The language used in this
Agreement will be deemed to be the language chosen by the parties to express
their mutual intent, and no rules of strict construction will be applied against
any party.

                  (o) The Company acknowledges that it has previously raised
capital (the "ISSUANCE") by the issuance of convertible debt and warrants with a
fixed conversion price and exercise price of $0.50 per share. Pursuant to the
terms of all convertible debt and warrants held by the Buyer, the Company
further acknowledges that the fixed conversion price of such convertible debt
and the exercise price of such warrants have been adjusted to $0.50 per share as
a result of the Issuance. Further, as a result of the Issuance, the number of
warrants has been increased pursuant to the terms of the outstanding warrants to
the denominations set forth in Schedule "II" hereto. No new consideration is
being given for this provision since it is a pre-existing obligation of the
Company to reset the price as set forth herein.

                  (p) The Company shall amend and restate all convertible debt
and warrants held by the Investor to be consistent with the preceding paragraph.
To the extent possible, the convertible debt and warrants shall be consolidated
in a manner that will not result in the loss of tacking to the holding period of
the original security under Rule 144 promulgated under the Securities Act of
1933, as amended.

         SECTION 3.        CONVERSION.

         (a) CONVERSION AT OPTION OF HOLDER.

                  (i) This Debenture shall be convertible into shares of Common
Stock at the option of the Holder, in whole or in part at any time and from time
to time, after the Original Issue Date (as defined in SECTION 5) (subject to the
limitations on conversion set forth in SECTION 3(B) hereof). The number of
shares of Common Stock issuable upon a conversion hereunder equals the quotient
obtained by dividing (x) the outstanding amount of this Debenture to be
converted by (y) the Conversion Price (as defined in SECTION 3(C)(I)). The
Obligor shall deliver Common Stock certificates to the Holder prior to the Fifth
(5th) Trading Day after a Conversion Date.

                                      -4-
<PAGE>

                  (ii) Notwithstanding anything to the contrary contained
herein, if on any Conversion Date: (1) the number of shares of Common Stock at
the time authorized, unissued and unreserved for all purposes, or held as
treasury stock, is insufficient to pay principal and interest hereunder in
shares of Common Stock; (2) the Common Stock is not listed or quoted for trading
on the OTC or on a Subsequent Market; (3) the Obligor has failed to timely
satisfy its conversion; or (4) the issuance of such shares of Common Stock would
result in a violation of SECTION 3(B), then, at the option of the Holder, the
Obligor, in lieu of delivering shares of Common Stock pursuant to SECTION
3(A)(I), shall deliver, within three (3) Trading Days of each applicable
Conversion Date, an amount in cash equal to the product of the outstanding
principal amount to be converted plus any interest due therein divided by the
Conversion Price, chosen by the Holder, and multiplied by the highest closing
price of the stock from date of the conversion notice till the date that such
cash payment is made.

         Further, if the Obligor shall not have delivered any cash due in
respect of conversion of this Debenture or as payment of interest thereon by the
fifth (5th) Trading Day after the Conversion Date, the Holder may, by notice to
the Obligor, require the Obligor to issue shares of Common Stock pursuant to
SECTION 3(C), except that for such purpose the Conversion Price applicable
thereto shall be the lesser of the Conversion Price on the Conversion Date and
the Conversion Price on the date of such Holder demand. Any such shares will be
subject to the provisions of this Section.

                  (iii) The Holder shall effect conversions by delivering to the
Obligor a completed notice in the form attached hereto as Exhibit A (a
"CONVERSION NOTICE"). The date on which a Conversion Notice is delivered is the
"CONVERSION DATE." Unless the Holder is converting the entire principal amount
outstanding under this Debenture, the Holder is not required to physically
surrender this Debenture to the Obligor in order to effect conversions.
Conversions hereunder shall have the effect of lowering the outstanding
principal amount of this Debenture plus all accrued and unpaid interest thereon
in an amount equal to the applicable conversion. The Holder and the Obligor
shall maintain records showing the principal amount converted and the date of
such conversions. In the event of any dispute or discrepancy, the records of the
Holder shall be controlling and determinative in the absence of manifest error.

         (b) LIMITATION OF CONVERSION BY THE HOLDER. A Holder may not convert
this Debenture or receive shares of Common Stock as payment of interest
hereunder to the extent such conversion or receipt of such interest payment
would (x) result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act and the rules promulgated thereunder) in excess of 4.99% of the
then issued and outstanding shares of Common Stock, including shares issuable
upon conversion of, and payment of interest on, this Debenture held by such
Holder after application of this Section, or (y) result in a violation of the
U.S. Department of Transportation foreign ownership regulations. Since the
Holder will not be obligated to report to the Obligor the number of shares of
Common Stock it may hold at the time of a conversion hereunder, unless the
conversion at issue would result in the issuance of shares of Common Stock in
excess of 4.99% of the then outstanding shares of Common Stock without regard to
any other shares which may be beneficially owned by the Holder or an affiliate
thereof, the Holder shall have the authority and obligation to determine whether
the restriction contained in this Section will limit any particular conversion
hereunder and to the extent that the Holder determines that the limitation
contained in this Section applies, the determination of which portion of the
principal amount of this Debenture is convertible shall be the responsibility
and obligation of the Holder. If the Holder has delivered a Conversion Notice

                                      -5-
<PAGE>

for a principal amount of this Debenture that, without regard to any other
shares that the Holder or its affiliates may beneficially own, would result in
the issuance in excess of the permitted amount hereunder, the Obligor shall
notify the Holder of this fact and shall honor the conversion for the maximum
principal amount permitted to be converted on such Conversion Date andeither
retain any principal amount tendered for conversion in excess of the permitted
amount hereunder for future conversions. The provisions of this Section may be
waived by a Holder (but only as to itself and not to any other Holder) upon not
less than 65 days prior notice to the Obligor. Other Holders shall be unaffected
by any such waiver. Notwithstanding anything in any agreement to the contrary,
the Buyer shall have no restriction on the conversion of any convertible debt or
warrants held by it or the sale of any stock, including, without the limitation,
any stock underlying any convertible debt or warrant; PROVIDED that such acts do
not violate the U.S. Department of Transportation foreign ownership regulations.

         (c) CONVERSION PRICE AND ADJUSTMENTS TO CONVERSION PRICE.

                  (i) The conversion price in effect on any Conversion Date
shall be equal to the lesser of (a) $0.50 (the "FIXED CONVERSION PRICE") or (b)
eighty percent (80%) of the lowest Closing Bid Price of the Common Stock during
the fifteen (15) trading days immediately preceding the Conversion Date or the
interest payment date, as applicable. The Fixed Conversion Price and the Market
Conversion Price are collectively referred to as the "CONVERSION PRICE." The
Conversion Price may be adjusted pursuant to the other terms of this Debenture.

                  (ii) If the Obligor, at any time while this Debenture is
outstanding, shall (a) pay a stock dividend or otherwise make a distribution or
distributions on shares of its Common Stock or any other equity or equity
equivalent securities payable in shares of Common Stock, (b) subdivide
outstanding shares of Common Stock into a larger number of shares, (c) combine
(including by way of reverse stock split) outstanding shares of Common Stock
into a smaller number of shares, or (d) issue by reclassification of shares of
the Common Stock any shares of capital stock of the Obligor, then the Fixed
Conversion Price shall be multiplied by a fraction of which the numerator shall
be the number of shares of Common Stock (excluding treasury shares, if any)
outstanding before such event and of which the denominator shall be the number
of shares of Common Stock outstanding after such event. Any adjustment made
pursuant to this Section shall become effective immediately after the record
date for the determination of stockholders entitled to receive such dividend or
distribution and shall become effective immediately after the effective date in
the case of a subdivision, combination or re-classification.

                  (iii) If the Obligor, at any time while this Debenture is
outstanding, shall issue rights, options or warrants to all holders of Common
Stock (and not to the Holder) entitling them to subscribe for or purchase shares
of Common Stock at a price per share less than the Fixed Conversion Price, then
the Fixed Conversion Price shall be multiplied by a fraction, of which the
denominator shall be the number of shares of the Common Stock (excluding
treasury shares, if any) outstanding on the date of issuance of such rights or
warrants (plus the number of additional shares of Common Stock offered for
subscription or purchase), and of which the numerator shall be the number of
shares of the Common Stock (excluding treasury shares, if any) outstanding on
the date of issuance of such rights or warrants, plus the number of shares which
the aggregate offering price of the total number of shares so offered would
purchase at the Fixed Conversion Price. Such adjustment shall be made whenever
such rights or warrants are issued, and shall become effective immediately after
the record date for the determination of stockholders entitled to receive such
rights, options or warrants. However, upon the expiration of any such right,
option or warrant to purchase shares of the Common Stock the issuance of which

                                      -6-
<PAGE>

resulted in an adjustment in the Fixed Conversion Price pursuant to this
Section, if any such right, option or warrant shall expire and shall not have
been exercised, the Fixed Conversion Price shall immediately upon such
expiration be recomputed and effective immediately upon such expiration be
increased to the price which it would have been (but reflecting any other
adjustments in the Fixed Conversion Price made pursuant to the provisions of
this Section after the issuance of such rights or warrants) had the adjustment
of the Fixed Conversion Price made upon the issuance of such rights, options or
warrants been made on the basis of offering for subscription or purchase only
that number of shares of the Common Stock actually purchased upon the exercise
of such rights, options or warrants actually exercised.

                  (iv) If the Obligor or any subsidiary thereof, as applicable,
at any time while this Debenture is outstanding, shall issue shares of Common
Stock or rights, warrants, options or other securities or debt that are
convertible into or exchangeable for shares of Common Stock ("COMMON STOCK
EQUIVALENTS") entitling any Person to acquire shares of Common Stock other than
Excluded Securities, at a price per share less than the Fixed Conversion Price
(if the holder of the Common Stock or Common Stock Equivalent so issued shall at
any time, whether by operation of purchase price adjustments, reset provisions,
floating conversion, exercise or exchange prices or otherwise, or due to
warrants, options or rights per share which is issued in connection with such
issuance, be entitled to receive shares of Common Stock at a price per share
which is less than the Fixed Conversion Price, such issuance shall be deemed to
have occurred for less than the Fixed Conversion Price), then, at the sole
option of the Holder, the Fixed Conversion Price shall be adjusted to mirror the
conversion, exchange or purchase price for such Common Stock or Common Stock
Equivalents (including any reset provisions thereof) at issue. Such adjustment
shall be made whenever such Common Stock or Common Stock Equivalents are issued.
The Obligor shall notify the Holder in writing, no later than one (1) business
day following the issuance of any Common Stock or Common Stock Equivalent
subject to this Section, indicating therein the applicable issuance price, or of
applicable reset price, exchange price, conversion price and other pricing
terms. No adjustment under this Section shall be made as a result of issuances
and exercises of options to purchase shares of Common Stock issued for
compensatory purposes pursuant to any of the Obligor's stock option or stock
purchase plans.

                  (v) If the Obligor, at any time while this Debenture is
outstanding, shall distribute to all holders of Common Stock (and not to the
Holder) evidences of its indebtedness or assets or rights or warrants to
subscribe for or purchase any security, then in each such case the Fixed
Conversion Price at which this Debenture shall thereafter be convertible shall
be determined by multiplying the Fixed Conversion Price in effect immediately
prior to the record date fixed for determination of stockholders entitled to
receive such distribution by a fraction of which the denominator shall be the
Closing Bid Price determined as of the record date mentioned above, and of which
the numerator shall be such Closing Bid Price on such record date less the then
fair market value at such record date of the portion of such assets or evidence
of indebtedness so distributed applicable to one outstanding share of the Common
Stock as determined by the Board of Directors in good faith. In either case the

                                      -7-
<PAGE>

adjustments shall be described in a statement provided to the Holder of the
portion of assets or evidences of indebtedness so distributed or such
subscription rights applicable to one share of Common Stock. Such adjustment
shall be made whenever any such distribution is made and shall become effective
immediately after the record date mentioned above.

                  (vi) In case of any reclassification of the Common Stock or
any compulsory share exchange pursuant to which the Common Stock is converted
into other securities, cash or property, the Holder shall have the right
thereafter to, at its option, (A) convert the then outstanding principal amount,
together with all accrued but unpaid interest and any other amounts then owing
hereunder in respect of this Debenture into the shares of stock and other
securities, cash and property receivable upon or deemed to be held by holders of
the Common Stock following such reclassification or share exchange, and the
Holder of this Debenture shall be entitled upon such event to receive such
amount of securities, cash or property as the shares of the Common Stock of the
Obligor into which the then outstanding principal amount, together with all
accrued but unpaid interest and any other amounts then owing hereunder in
respect of this Debenture could have been converted immediately prior to such
reclassification or share exchange would have been entitled, or (B) require the
Obligor to prepay the outstanding principal amount of this Debenture, plus all
interest and other amounts due and payable thereon. The entire prepayment price
shall be paid in cash. This provision shall similarly apply to successive
reclassifications or share exchanges.

                  (vii) The Obligor shall at all times reserve and keep
available out of its authorized Common Stock the full number of shares of Common
Stock issuable upon conversion of all outstanding amounts under this Debenture;
and within three (3) Business Days following the receipt by the Obligor of a
Holder's notice that such minimum number of Underlying Shares is not so
reserved, the Obligor shall promptly reserve a sufficient number of shares of
Common Stock to comply with such requirement.

                  (viii) All calculations under this SECTION 3 shall be rounded
up to the nearest $0.0001 or whole share.

                  (ix) Whenever the Conversion Price is adjusted pursuant to
SECTION 3 hereof, the Obligor shall promptly mail to the Holder a notice setting
forth the Conversion Price after such adjustment and setting forth a brief
statement of the facts requiring such adjustment.

                  (x) If (A) the Obligor shall declare a dividend (or any other
distribution) on the Common Stock; (B) the Obligor shall declare a special
nonrecurring cash dividend on or a redemption of the Common Stock; (C) the
Obligor shall authorize the granting to all holders of the Common Stock rights
or warrants to subscribe for or purchase any shares of capital stock of any
class or of any rights; (D) the approval of any stockholders of the Obligor
shall be required in connection with any reclassification of the Common Stock,
any consolidation or merger to which the Obligor is a party, any sale or
transfer of all or substantially all of the assets of the Obligor, of any
compulsory share exchange whereby the Common Stock is converted into other
securities, cash or property; or (E) the Obligor shall authorize the voluntary
or involuntary dissolution, liquidation or winding up of the affairs of the
Obligor; then, in each case, the Obligor shall cause to be filed at each office
or agency maintained for the purpose of conversion of this Debenture, and shall
cause to be mailed to the Holder at its last address as it shall appear upon the

                                      -8-
<PAGE>

stock books of the Obligor, at least twenty (20) calendar days prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution, redemption, rights or warrants, or if a record is not to be taken,
the date as of which the holders of the Common Stock of record to be entitled to
such dividend, distributions, redemption, rights or warrants are to be
determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of the Common Stock
of record shall be entitled to exchange their shares of the Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange, provided, that the
failure to mail such notice or any defect therein or in the mailing thereof
shall not affect the validity of the corporate action required to be specified
in such notice. The Holder is entitled to convert this Debenture during the
20-day calendar period commencing the date of such notice to the effective date
of the event triggering such notice.

                  (xi) In case of any (1) merger or consolidation of the Obligor
or any subsidiary of the Obligor with or into another Person, or (2) sale by the
Obligor or any subsidiary of the Obligor of more than one-half of the assets of
the Obligor in one or a series of related transactions, a Holder shall have the
right to (A) exercise any rights under SECTION 2(B), (B) convert the aggregate
amount of this Debenture then outstanding into the shares of stock and other
securities, cash and property receivable upon or deemed to be held by holders of
Common Stock following such merger, consolidation or sale, and such Holder shall
be entitled upon such event or series of related events to receive such amount
of securities, cash and property as the shares of Common Stock into which such
aggregate principal amount of this Debenture could have been converted
immediately prior to such merger, consolidation or sales would have been
entitled, or (C) in the case of a merger or consolidation, require the surviving
entity to issue to the Holder a convertible Debenture with a principal amount
equal to the aggregate principal amount of this Debenture then held by such
Holder, plus all accrued and unpaid interest and other amounts owing thereon,
which such newly issued convertible Debenture shall have terms identical
(including with respect to conversion) to the terms of this Debenture, and shall
be entitled to all of the rights and privileges of the Holder of this Debenture
set forth herein and the agreements pursuant to which this Debentures were
issued. In the case of clause (C), the conversion price applicable for the newly
issued shares of convertible preferred stock or convertible Debentures shall be
based upon the amount of securities, cash and property that each share of Common
Stock would receive in such transaction and the Conversion Price in effect
immediately prior to the effectiveness or closing date for such transaction. The
terms of any such merger, sale or consolidation shall include such terms so as
to continue to give the Holder the right to receive the securities, cash and
property set forth in this Section upon any conversion or redemption following
such event. This provision shall similarly apply to successive such events.

         (d)      Other Provisions.

                  (i) The Obligor covenants that it will at all times reserve
and keep available out of its authorized and unissued shares of Common Stock
solely for the purpose of issuance upon conversion of this Debenture and payment
of interest on this Debenture, each as herein provided, free from preemptive
rights or any other actual contingent purchase rights of persons other than the
Holder, not less than such number of shares of the Common Stock as shall

                                      -9-
<PAGE>

(subject to any additional requirements of the Obligor as to reservation of such
shares set forth in this Debenture) be issuable (taking into account the
adjustments and restrictions of SECTIONS 2(B) AND 3(C)) upon the conversion of
the outstanding principal amount of this Debenture and payment of interest
hereunder. The Obligor covenants that all shares of Common Stock that shall be
so issuable shall, upon issue, be duly and validly authorized, issued and fully
paid, nonassessable and, if the Underlying Shares Registration Statement has
been declared effective under the Securities Act, registered for public sale in
accordance with such Underlying Shares Registration Statement.

                  (ii) Upon a conversion hereunder the Obligor shall not be
required to issue stock certificates representing fractions of shares of the
Common Stock, but may if otherwise permitted, make a cash payment in respect of
any final fraction of a share based on the Closing Bid Price at such time. If
the Obligor elects not, or is unable, to make such a cash payment, the Holder
shall be entitled to receive, in lieu of the final fraction of a share, one
whole share of Common Stock.

                  (iii) The issuance of certificates for shares of the Common
Stock on conversion of this Debenture shall be made without charge to the Holder
thereof for any documentary stamp or similar taxes that may be payable in
respect of the issue or delivery of such certificate, provided that the Obligor
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 such certificate upon
conversion in a name other than that of the Holder of such Debenture so
converted and the Obligor shall not be required to issue or deliver such
certificates unless or until the person or persons requesting the issuance
thereof shall have paid to the Obligor the amount of such tax or shall have
established to the satisfaction of the Obligor that such tax has been paid.

                  (iv) Nothing herein shall limit a Holder's right to pursue
actual damages or declare an Event of Default pursuant to SECTION 2 herein for
the Obligor's failure to deliver certificates representing shares of Common
Stock upon conversion within the period specified herein and such Holder shall
have the right to pursue all remedies available to it at law or in equity
including, without limitation, a decree of specific performance and/or
injunctive relief, in each case without the need to post a bond or provide other
security. The exercise of any such rights shall not prohibit the Holder from
seeking to enforce damages pursuant to any other Section hereof or under
applicable law.

                  In addition to any other rights available to the Holder, if
the Obligor fails to deliver to the Holder such certificate or certificates
pursuant to SECTION 3(A)(I) by the fifth (5th) Trading Day after the Conversion
Date, and if after such fifth (5th) Trading Day the Holder purchases (in an open
market transaction or otherwise) Common Stock to deliver in satisfaction of a
sale by such Holder of the Underlying Shares which the Holder anticipated
receiving upon such conversion (a "BUY-IN"), then the Obligor shall (A) pay in
cash to the Holder (in addition to any remedies available to or elected by the
Holder) the amount by which (x) the Holder's total purchase price (including
brokerage commissions, if any) for the Common Stock so purchased exceeds (y) the
product of (1) the aggregate number of shares of Common Stock that such Holder
anticipated receiving from the conversion at issue multiplied by (2) the market
price of the Common Stock at the time of the sale giving rise to such purchase
obligation and (B) at the option of the Holder, either reissue a Debenture in

                                      -10-
<PAGE>

the principal amount equal to the principal amount of the attempted conversion
or deliver to the Holder the number of shares of Common Stock that would have
been issued had the Obligor timely complied with its delivery requirements under
SECTION 3(A)(I). For example, if the Holder purchases Common Stock having a
total purchase price of $11,000 to cover a Buy-In with respect to an attempted
conversion of Debentures with respect to which the market price of the
Underlying Shares on the date of conversion was a total of $10,000 under clause
(A) of the immediately preceding sentence, the Obligor shall be required to pay
the Holder $1,000. The Holder shall provide the Obligor written notice
indicating the amounts payable to the Holder in respect of the Buy-In.

                  (v) The Obligor shall reserve 20% of the 24.99% Foreign
Ownership Pool (as herein defined) for the Holder (the "HOLDER RESERVE") and
shall not issue any shares of Common Stock to any third party that would
decrease the number of shares of voting Common Stock in the Holder Reserve. The
"24.99% FOREIGN OWNERSHIP POOL" means the maximum number of shares of Common
Stock that may be owned by persons or entities that are non-U.S. citizens, as
determined pursuant to the U.S. Department of Transportation foreign ownership
regulations. (BY WAY OF EXAMPLE, IF THE 24.99% FOREIGN OWNERSHIP POOL EQUALS
24,999 SHARES OF COMMON STOCK, THE BUYER RESERVE SHALL BE 4,999 SHARES.)

                  (vi) HOLDER'S RIGHTS UPON LIQUIDATION.

                  A. Upon any Liquidation (as defined below) the Holder shall be
                  entitled to receive an amount equal to the greater of (i) the
                  amount required to be paid under this Debenture (including all
                  principal, interest, and any redemption amounts) or (ii) the
                  Assumed Conversion Amount. Thereafter, no further
                  distributions shall be made to the Holder of this Debenture.

                  B. "LIQUIDATION" means (i) a liquidation, dissolution or
                  winding up of the Company, whether voluntary or involuntary,
                  (ii) a consolidation or merger of the Company with or into any
                  other person(s), entity or entities in which less than a
                  majority of the outstanding voting power of the surviving
                  person(s), entity or entities is held by persons or entities
                  who were stockholders of the Company prior to such event,
                  (iii) a sale or other disposition (whether in a single
                  transaction or a series of related transactions) of
                  substantially all of the assets of the Company, or (iv) a
                  transaction pursuant to which the Company becomes a private
                  company not required to file periodic reports with the
                  Commission.

                  C. "ASSUMED CONVERSION AMOUNT" means the total amount of
                  proceeds that would be payable to the Holder on a Liquidation
                  if immediately prior to such Liquidation the entire principal
                  outstanding and accrued interest under this Debenture was
                  converted into a number of shares of Common Stock at the then
                  current Conversion Price (assuming for these purposes that the
                  number of authorized shares of Common Stock has been is
                  sufficient for the full conversion of the Debenture and
                  without taking into effect any limitations on conversions set
                  forth in the Debenture).

workout, and/or in connection with the rendering of legal advice as to the

due to the Holder, (iii) defending or prosecuting any proceeding or any
counterclaim to any proceeding or appeal; or (iv) the protection, preservation
or enforcement of any rights or remedies of the Holder.

         SECTION 12. Any waiver by the Holder of a breach of any provision of
this Debenture shall not operate as or be construed to be a waiver of any other
breach of such provision or of any breach of any other provision of this
Debenture. The failure of the Holder to insist upon strict adherence to any term
of this Debenture on one or more occasions shall not be considered a waiver or
deprive that party of the right thereafter to insist upon strict adherence to
that term or any other term of this Debenture. Any waiver must be in writing.

         SECTION 13. If any provision of this Debenture is invalid, illegal or
         unenforceable, the balance of this Debenture shall remain in effect,
         and if any provision is inapplicable to any person or circumstance, it
         shall nevertheless remain applicable to all other persons and
         circumstances. If it shall be found that any interest or other amount
         deemed interest due hereunder shall violate applicable laws governing
         usury, the applicable rate of interest due hereunder shall
         automatically be lowered to equal the maximum permitted rate of
         interest. The Obligor covenants (to the extent that it may lawfully do
         so) that it shall not at any time insist upon, plead, or in any manner
         whatsoever claim or take the benefit or advantage of, any stay,
         extension or usury law or other law which would prohibit or forgive the
         Obligor from paying all or any portion of the principal of or interest
         on this Debenture as contemplated herein, wherever enacted, now or at
         any time hereafter in force, or which may affect the covenants or the
         performance of this indenture, and the Obligor (to the extent it may
         lawfully do so) hereby expressly waives all benefits or advantage of
         any such law, and covenants that it will not, by resort to any such
         law, hinder, delay or impeded the execution of any power herein granted
         to the Holder, but will suffer and permit the execution of every such
         as though no such law has been enacted.

         SECTION 14. Whenever any payment or other obligation hereunder shall be
due on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day.

         SECTION 15. THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY
WAIVE THE RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY
LITIGATION BASED HEREON OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS
AGREEMENT OR ANY TRANSACTION DOCUMENT OR ANY COURSE OF CONDUCT, COURSE OF
DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY. THIS
PROVISION IS A MATERIAL INDUCEMENT FOR THE PARTIES' ACCEPTANCE OF THIS
AGREEMENT.
