          2.   LENDER REPRESENTATIONS, WARRANTIES, ETC.; ACCESS TO INFORMATION;
INDEPENDENT INVESTIGATION.

          The Lender represents and warrants to, and covenants and agrees with,
the Company as follows:

          A.   Without limiting Lender's right to sell the Securities pursuant
to an effective registration statement or otherwise in compliance with the 1933
Act, the Lender is purchasing the Securities for its own account for investment
only and not with a view towards the public sale or distribution thereof and not
with a view to or for sale in connection with any distribution thereof.

          B.   The Lender is (i) an "accredited investor" as that term is
defined in Rule 501 of the General Rules and Regulations under the 1933 Act by
reason of Rule 501(a)(3), (ii) experienced in making investments of the kind
described in this Agreement and the related documents, (iii) able, by reason of
the business and financial experience of its officers (if an entity) and
professional advisors (who are not affiliated with or compensated in any way by
the Company or any of its Affiliates or selling agents), to protect its own
interests in connection with the transactions described in this Agreement, and
the related documents, and to evaluate the merits and risks of an investment in
the Securities, and (iv) able to afford the entire loss of its investment in the
Securities.

          C.   All subsequent offers and sales of the Securities by the Lender
shall be made pursuant to registration of the relevant Securities under the 1933
Act or pursuant to an exemption from registration.

          D.   The Lender understands that the Securities are being offered and
sold to it in reliance on specific exemptions from the registration requirements
of the 1933 Act and state securities laws and that the Company is relying upon
the truth and accuracy of, and the Lender's compliance with, the
representations, warranties, agreements, acknowledgments and understandings of
the Lender set forth herein in order to determine the availability of such
exemptions and the eligibility of the Lender to acquire the Securities.

          E.   The Lender and its advisors, if any, have been furnished with or
have been given access to all materials relating to the business, finances and
operations of the Company and materials relating to the offer and sale of the
Debentures and the Warrants which have been requested by the Lender, including
those set forth on in any annex attached hereto. The Lender and its advisors, if
any, have been afforded the opportunity to ask questions of the Company and its
management and have received complete and satisfactory answers to any such
inquiries. Without limiting the generality of the foregoing, the Lender has also
had the opportunity to obtain and to review the Company's filings on EDGAR
listed on ANNEX VI hereto (the documents listed on such Annex VI, to the extent
available on EDGAR or otherwise provided to the Lender as indicated on said
Annex VI, collectively, the "Company's SEC Documents").

                                        5
<PAGE>

          F.   The Lender understands that its investment in the Securities
involves a high degree of risk and has reviewed the material under the caption
"Risk Factors" contained in the Company's Annual Report on Form 10-KSB for the
fiscal year ended December 31, 2002 listed on Annex VI.

          G.   The Lender hereby represents that, in connection with its
purchase of the Securities, it has not relied on any statement or representation
by the Company or the Finder or any of their respective officers, directors and
employees or any of their respective attorneys or agents or the Finder, except
as specifically set forth herein. The Finder is a third party beneficiary of
this provision.

          H.   The Lender 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.

          I.   This Agreement and the other Transaction Agreements to which the
Lender is a party, and the transactions contemplated thereby, have been duly and
validly authorized, executed and delivered on behalf of the Lender and are valid
and binding agreements of the Lender enforceable in accordance with their
respective terms, subject as to enforceability to general principles of equity
and to bankruptcy, insolvency, moratorium and other similar laws affecting the
enforcement of creditors' rights generally.

          3.   COMPANY REPRESENTATIONS, ETC. The Company represents and warrants
to the Lender as of the date hereof and as of the Closing Date that, except as
otherwise provided in the ANNEX V hereto or in the Company's SEC Documents:

          A.   RIGHTS OF OTHERS AFFECTING THE TRANSACTIONS. There are no
preemptive rights of any shareholder of the Company, as such, to acquire the
Debentures, the Warrants or the Shares. No party other than a Lender or an Other
Lender has a currently exercisable right of first refusal which would be
applicable to any or all of the transactions contemplated by the Transaction
Agreements.

          B.   STATUS. The Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of Incorporation and
has the requisite corporate power to own its properties and to carry on its
business as now being conducted. The Company is duly qualified as a foreign
corporation to do business and is in good standing in each jurisdiction where
the nature of the business conducted or property owned by it makes such
qualification necessary, other than those jurisdictions in which the failure to
so qualify would not have or result in a Material Adverse Effect. The Company
has registered its stock and is obligated to file reports pursuant to Section 12
or Section 15(d) of the Securities and Exchange Act of 1934, as amended (the
"1934 Act"). The Common Stock is listed and quoted on the Principal Trading
Market. The Company has received no notice, either oral or written, with respect
to the continued eligibility of the Common Stock for such listing and quotation
on the Principal Trading Market, and the Company has maintained all requirements
on its part for the continuation of such listing and quotation.

of which none are outstanding as of the date hereof. All issued and outstanding
shares of Common Stock have been duly authorized and validly issued and are
fully paid and non-assessable. The Company has sufficient authorized and
unissued shares of Common Stock as may be necessary to effect the issuance of
the Shares. The Shares have been duly authorized and, when issued on the
conversion of, or as interest on, the Debentures or upon exercise of the
Warrants in accordance with its terms, will be duly and validly issued, fully
paid and non-assessable and will not subject the Holder thereof to personal
liability by reason of being such Holder.

          D.   TRANSACTION AGREEMENTS AND STOCK. This Agreement and each of the
other Transaction Agreements, and the transactions contemplated thereby, have
been duly and validly authorized by the Company, this Agreement has been duly
executed and delivered by the Company and this Agreement is, and the Debentures,

delivered by the Company, will be, valid and binding agreements of the Company
enforceable in accordance with their respective terms, subject as to
enforceability to general principles of equity and to bankruptcy, insolvency,
moratorium, and other similar laws affecting the enforcement of creditors'
rights generally.

          E.   NON-CONTRAVENTION. The execution and delivery of this Agreement
and each of the other Transaction Agreements by the Company, the issuance of the
Securities, and the consummation by the Company of the other transactions
contemplated by this Agreement, the Debentures, the Warrants and the other
Transaction Agreements do not and will not conflict with or result in a breach
by the Company of any of the terms or provisions of, or constitute a default
under (i) the certificate of incorporation or by-laws of the Company, each as
currently in effect, (ii) any indenture, mortgage, deed of trust, or other
material agreement or instrument to which the Company is a party or by which it
or any of its properties or assets are bound, including any listing agreement
for the Common Stock except as herein set forth, or (iii) to its knowledge, any
existing applicable law, rule, or regulation or any applicable decree, judgment,
or order of any court, United States federal or state regulatory body,
administrative agency, or other governmental body having jurisdiction over the
Company or any of its properties or assets, except such conflict, breach or
default which would not have or result in a Material Adverse Effect.

          F.   FILINGS. None of the Company's SEC Documents contained, at the
time they were filed, any untrue statement of a material fact or omitted to
state any material fact required to be stated therein or necessary to make the
statements made therein in light of the circumstances under which they were

                                        7

          G.   ABSENCE OF CERTAIN CHANGES. Since the Last Audited Date, there
has been no material adverse change and no Material Adverse Effect, except as
disclosed in the Company's SEC Documents. Since the Last Audited Date, except as
provided in the Company's SEC Documents, the Company has not (i) incurred or
become subject to any material liabilities (absolute or contingent) except

          H.   FULL DISCLOSURE. To the best of the Company's knowledge, there is
no fact known to the Company (other than general economic conditions known to
the public generally or as disclosed in the Company's SEC Documents) that has
not been disclosed in writing to the Lender that would reasonably be expected to
have or result in a Material Adverse Effect.

          I.   ABSENCE OF LITIGATION. There is no action, suit, proceeding,
inquiry or investigation before or by any court, public board or body pending
or, to the knowledge of the Company, threatened against or affecting the Company
before or by any governmental authority or nongovernmental department,
commission, board, bureau, agency or instrumentality or any other person,
wherein an unfavorable decision, ruling or finding would have a Material Adverse
Effect or which would adversely affect the validity or enforceability of, or the
authority or ability of the Company to perform its obligations under, any of the
Transaction Agreements. The Company is not aware of any valid basis for any such
claim that (either individually or in the aggregate with all other such events
and circumstances) could reasonably be expected to have a Material Adverse
Effect. There are no outstanding or unsatisfied judgments, orders, decrees,
writs, injunctions or stipulations to which the Company is a party or by which
it or any of its properties is bound, that involve the transaction contemplated
herein or that, alone or in the aggregate, could reasonably be expect to have a
Material Adverse Effect.

          J.   ABSENCE OF EVENTS OF DEFAULT. Except as set forth in Section 3(e)
hereof, no Event of Default (or its equivalent term), as defined in the
respective agreement to which the Company is a party, and no event which, with
the giving of notice or the passage of time or both, would become an Event of
Default (or its equivalent term) (as so defined in such agreement), has occurred
and is continuing, which would have a Material Adverse Effect.

     or vacated.

          L.   NO UNDISCLOSED LIABILITIES OR EVENTS. To the best of the
Company's knowledge, the Company has no liabilities or obligations other than
those disclosed in the Transaction Agreements or the Company's SEC Documents or
those incurred in the ordinary course of the Company's business since the Last
Audited Date, or which individually or in the aggregate, do not or would not
have a Material Adverse Effect. No event or circumstances has occurred or exists
with respect to the Company or its properties, business, operations, condition
(financial or otherwise), or results of operations, which, under applicable law,
rule or regulation, requires public disclosure or announcement prior to the date
hereof by the Company but which has not been so publicly announced or disclosed.
There are no proposals currently under consideration or currently anticipated to
be under consideration by the Board of Directors or the executive officers of
the Company which proposal would (x) change the certificate of incorporation or
other charter document or by-laws of the Company, each as currently in effect,
with or without shareholder approval, which change would reduce or otherwise
adversely affect the rights and powers of the shareholders of the Common Stock
or (y) materially or substantially change the business, assets or capital of the
Company, including its interests in subsidiaries.

          M.   NO DEFAULT. Neither the Company nor any of its subsidiaries is in
default in the performance or observance of any material obligation, agreement,
covenant or condition contained in any material indenture, mortgage, deed of
trust or other material instrument or agreement to which it is a party or by
which it or its property is bound.

          N.   NO INTEGRATED OFFERING. Neither the Company nor any of its
Affiliates nor any Person acting on its or their behalf has, directly or
indirectly, at any time since March 1, 2003, made any offer or sales of any
security or solicited any offers to buy any security under circumstances that
would eliminate the availability of the exemption from registration under
Regulation D in connection with the offer and sale of the Securities as
contemplated hereby.

          O.   DILUTION. The number of shares issuable on conversion of the
Debentures and upon exercise of the Warrants may have a dilutive effect on the
ownership interests of the other shareholders (and Persons having the right to
become shareholders) of the Company. The Company's executive officers and
directors have studied and fully understand the nature of the Securities being
sold hereby and recognize that they have such a potential dilutive effect. The
board of directors of the Company has concluded, in its good faith business
judgment, that such issuance is in the best interests of the Company. The
Company specifically acknowledges that its obligation to issue the Conversion
Shares upon conversion of the Debentures and the Warrant Shares upon exercise of
the Warrants is binding upon the Company and enforceable regardless of the
dilution such issuance may have on the ownership interests of other shareholders
of the Company, and the Company will honor such obligations, including honoring
every Notice of

<PAGE>

Conversion (as contemplated by the Debentures) and every Notice of Exercise (as
contemplated by the Warrants), unless the Company is subject to an injunction
(which injunction was not sought by the Company) prohibiting the Company from
doing so.

          P.   FEES TO BROKERS, FINDERS AND OTHERS. Except for payment of the
fees to the Finder's Compensation (as defined below) to the Finder, payment of
which is the sole responsibility of the Company, the Company has taken no action
which would give rise to any claim by any Person for brokerage commission,
finder's fees or similar payments by Lender relating to this Agreement or the
transactions contemplated hereby. Lender shall have no obligation with respect
to such fees or with respect to any claims made by or on behalf of other Persons
for fees of a type contemplated in this paragraph that may be due in connection
with the transactions contemplated hereby. The Company shall indemnify and hold
harmless each of Lender, its employees, officers, directors, agents, and
partners, and their respective Affiliates, from and against all claims, losses,
damages, costs (including the costs of preparation and attorney's fees) and
expenses suffered in respect of any such claimed or existing fees, as and when
incurred. The term "Finder's Compensation" means: (x) in connection with the
consummation of the transactions contemplated by this Agreement, (1) a cash fee
and expense allowance in the amount contemplated by the Joint Escrow
Instructions, and (2) warrants to purchase Common Stock for a number of shares
equal to ten percent (10%) of the Warrant Shares for all Lenders.

          Q.   CONFIRMATION. The Company confirms that all statements of the
Company contained herein shall survive acceptance of this Agreement by the
Lender. The Company agrees that, if any events occur or circumstances exist
prior to the Closing Date or the release of the Purchase Price to the Company
which would make any of the Company's representations, warranties, agreements or
other information set forth herein materially untrue or materially inaccurate as
of such date, the Company shall immediately notify the Lender (directly or
through its counsel, if any) and the Escrow Agent in writing prior to such date
of such fact, specifying which representation, warranty or covenant is affected
and the reasons therefor.

          4.   CERTAIN COVENANTS AND ACKNOWLEDGMENTS.

          A.   TRANSFER RESTRICTIONS. The Lender acknowledges that (1) the
Securities have not been and are not being registered under the provisions of
the 1933 Act and, except as provided in the Registration Rights Provisions or
otherwise included in an effective registration statement, the Shares have not
been and are not being registered under the 1933 Act, and may not be transferred
unless (A) subsequently registered thereunder or (B) the Lender shall have
delivered to the Company an opinion of counsel, reasonably satisfactory in form,
scope and substance to the Company, to the effect that the Securities to be sold
or transferred may be sold or transferred pursuant to an exemption from such
registration; (2) any sale of the Securities made in reliance on Rule 144
promulgated under the 1933 Act may be made only in accordance with the terms of
said Rule and further, if said Rule is not applicable, any resale of such
Securities under circumstances in which the seller, or the Person through whom
the sale is made, may be deemed to be an underwriter, as that term is used in
the 1933 Act, may require

<PAGE>

compliance with some other exemption under the 1933 Act or the rules and
regulations of the SEC thereunder; and (3) neither the Company nor any other
Person is under any obligation to register the Securities (other than pursuant
to the Registration Rights Provisions) under the 1933 Act or to comply with the
terms and conditions of any exemption thereunder.

          B.   RESTRICTIVE LEGEND. The Lender acknowledges and agrees that,
until such time as the relevant Shares have been registered under the 1933 Act,
as contemplated by the Registration Rights Provisions and sold in accordance
with an effective Registration Statement or otherwise in accordance with another
effective registration statement, the certificates and other instruments
representing any of the Securities shall bear a restrictive legend in
substantially the following form (and a stop-transfer order may be placed
against transfer of any such Securities):

     THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
     AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD OR
     OFFERED FOR SALE IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR
     THE SECURITIES OR AN OPINION OF COUNSEL OR OTHER EVIDENCE ACCEPTABLE TO THE
     COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

          C.   FILINGS. The Company undertakes and agrees to make all necessary
filings in connection with the sale of the Securities to the Lender under any
United States laws and regulations applicable to the Company, or by any domestic
securities exchange or trading market, and to provide a copy thereof to the
Lender promptly after such filing.

          D.   REPORTING STATUS. So long as the Lender beneficially owns any of
the Securities, the Company shall file all reports required to be filed with the
SEC pursuant to Section 13 or 15(d) of the 1934 Act, shall take all reasonable
action under its control to ensure that adequate current public information with
respect to the Company, as required in accordance with Rule 144(c)(2) of the
1933 Act, is publicly available, and shall not terminate its status as an issuer
required to file reports under the 1934 Act even if the 1934 Act or the rules
and regulations thereunder would permit such termination. The Company will take
all reasonable action under its control to maintain the continued listing and
quotation and trading of its Common Stock (including, without limitation, all
Registrable Securities) on the Principal Trading Market or a listing on the
NASDAQ/Small Cap or National Markets and, to the extent applicable to it, will
comply in all material respects with the Company's reporting, filing and other
obligations under the by-laws or rules of the Principal Trading Market and/or
the National Association of Securities Dealers, Inc., as the case may be,
applicable to it at least through the date which is sixty (60) days after the
later of the date on which (x) all of the Debentures have been converted or been
paid in full or (y) all of the Warrants have been exercised or have expired.

          E.   USE OF PROCEEDS. The Company will use the proceeds received
hereunder

<PAGE>

(excluding amounts paid by the Company for Finder's Compensation in connection
with the sale of the Securities) for general corporate purposes.

          F.   WARRANTS. The Company agrees to issue to the Lender on the
Closing Date transferable warrants (the "Warrants"), with cashless exercise
rights (subject to certain conditions provided in the Warrants) for the purchase
of two (2) shares of Common Stock for each $1 of Purchase Price. The exercise
price of the Warrants will be equal to $0.15, subject to adjustment as provided
in the Warrant. The Warrants will expire on the last day of the calendar month
in which the third annual anniversary of the Closing Date occurs, subject to
earlier expiration as provided in the Warrants. Each of the Warrants shall be in
the form annexed hereto as ANNEX IV, and shall have Registration Rights
Provisions.

          G.   PIGGY-BACK RIGHTS; RULE 144.

          (i)  The Holder shall have piggy-back registration rights with respect
to the Registrable Securities (which term, for all purposes of this Section
4(g), includes shares issuable on the subsequent conversion of the Debentures or
the exercise of the Warrants) subject to the conditions set forth below. If the
Company participates (whether voluntarily or by reason of an obligation to a
third party) in the registration of any shares of the Company's stock (other
than a registration on Form S-8 or on Form S-4), the Company shall give written
notice thereof to the Holder and the Holder shall have the right, exercisable
within ten (10) business days after receipt of such notice, to demand inclusion
of all or a portion of the Holder's Registrable Securities in such registration
statement. If the Holder exercises such election, the Registrable Securities so
designated shall be included in the registration statement (without any
holdbacks) at no cost or expense to the Holder (other than any commissions, if
any, relating to the sale of Holder's shares). Each Holder's rights under this
Section 4(g)(i) shall expire at such time as such Holder can sell all of such
Holder's remaining Registrable Securities under Rule 144 without volume or other
restrictions or limit.

          (ii) With a view to making available to the Holder 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 Investor to sell securities of
the Company to the public without registration (collectively, "Rule 144"), 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;
and

          (c)  furnish to the Holder so long as such party 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) if not available on the SEC's EDGAR system, a copy of
the most recent annual or quarterly report of the

<PAGE>

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 Holder to
sell such securities pursuant to Rule 144 without registration; and

          (d)   at the request of any Holder then holding Registrable
Securities, give its transfer agent (the "Transfer Agent") instructions
(supported by an opinion of Company counsel, if required or requested by the
Transfer Agent) to the effect that, upon the Transfer Agent's receipt from such
Holder of

     (i) a certificate (a "Rule 144 Certificate") certifying (A) that the
     Holder's holding period (as determined in accordance with the provisions of
     Rule 144) for the Shares which the Holder proposes to sell (the "Securities
     Being Sold") is not less than (1) year and (B) as to such other matters as
     may be appropriate in accordance with Rule 144 under the Securities Act,
     and

     (ii) an opinion of counsel acceptable to the Company (for which purposes it
     is agreed that Krieger & Prager LLP shall be deemed acceptable if not given
     by Company counsel) that, based on the Rule 144 Certificate, Securities
     Being Sold may be sold pursuant to the provisions of Rule 144, even in the
     absence of an effective registration statement,

the Transfer Agent is to effect the transfer of the Securities Being Sold and
issue to the buyer(s) or transferee(s) thereof one or more stock certificates
representing the transferred Securities Being Sold without any restrictive
legend and without recording any restrictions on the transferability of such
shares on the Transfer Agent's books and records (except to the extent any such
legend or restriction results from facts other than the identity of the relevant
Holder, as the seller or transferor thereof, or the status, including any
relevant legends or restrictions, of the shares of the Securities Being Sold
while held by the Lender). If the Transfer Agent reasonably requires any
additional documentation at the time of the transfer, the Company shall deliver
or cause to be delivered all such reasonable additional documentation as may be
necessary to effectuate the issuance of an unlegended certificate.

          (iii) Notwithstanding the foregoing, if at any time or from time to
time after the date of effectiveness of the registration statement, the Company
notifies the Holder in writing of the existence of a Potential Material Event
(as defined below), the Holder shall not offer or sell any Registrable
Securities, or engage in any other transaction involving or relating to the
Registrable Securities, from the time of the giving of notice with respect to a
Potential Material Event until the Holder receives written notice from the
Company that such Potential Material Event either has been disclosed to the
public or no longer constitutes a Potential Material Event; PROVIDED, HOWEVER,
that the Company may not so suspend such right other than during a Permitted
Suspension Period. The term "Potential Material Event" means any of the
following: (i) the possession by the Company of material information not ripe
for disclosure in a registration statement, which shall be evidenced by
determinations in good faith by the Board of Directors of the Company that
disclosure of such information in the registration statement would be

<PAGE>

detrimental to the business and affairs of the Company; or (ii) any material
engagement or activity by the Company which would, in the good faith
determination of the Board of Directors of the Company, be adversely affected by
disclosure in a registration statement at such time, which determination shall
be accompanied by a good faith determination by the Board of Directors of the
Company that the registration statement would be materially misleading absent
the inclusion of such information. The term "Permitted Suspension Period" means
one or more suspension periods during any consecutive 12-month period which
suspension periods, in the aggregate, do not exceed fifty (50) days, provided,
however, that no one such suspension period shall either (i) be for more than
twenty (20) days or (ii) begin less than ten (10) business days after the last
day of the preceding suspension (whether or not such last day was during or
after a Permitted Suspension Period).

          H.   AVAILABLE SHARES. The Company shall have at all times authorized
and reserved for issuance, free from preemptive rights, a number of shares (the
"Minimum Available Shares") at least equal to (x) one hundred twenty percent
(120%) of the number of shares of Common Stock issuable as may be required to
satisfy the conversion rights of the Holders of principal and interest on all
outstanding Convertible Debentures plus (y) one hundred percent (100%) of the
number of shares issuable upon exercise of all outstanding Warrants held by all
Holders (in each case, whether such Convertible Debentures or Warrants were
originally issued to the Holder, the Lender or to any other party). For the
purposes of such calculations, the Company should assume that all such
Convertible Debentures were then convertible and all Warrants were then
exercisable without regard to any restrictions which might limit any Holder's
right to convert any of the Convertible Debentures or to exercise any of the
Warrants held by any Holder.

          I.   PUBLICITY, FILINGS, RELEASES, ETC. Each of the parties agrees
that it will not disseminate any information relating to the Transaction
Agreements or the transactions contemplated thereby, including issuing any press
releases, holding any press conferences or other forums, or filing any reports
(collectively, "Publicity"), without giving the other party reasonable advance
notice and an opportunity to comment on the contents thereof. Neither party will
include in any such Publicity any statement or statements or other material to
which the other party reasonably objects. In furtherance of the foregoing, the
Company will provide to the Lender drafts of the applicable text of any filing
intended to be made with the SEC which refers to the Transaction Agreements or
the transactions contemplated thereby as soon as practicable (but at least three
(3) business days before such filing will be made) and will not include in such
filing any statement or statements or other material to which the other party
reasonably objects. Notwithstanding the foregoing, each of the parties hereby
consents to the inclusion of the text of the Transaction Agreements in filings
made with the SEC (but any descriptive text accompanying or part of such filing
shall be subject to the other provisions of this paragraph.)

          5.   TRANSFER AGENT INSTRUCTIONS.

          A.   The Company warrants that, with respect to the Securities, other
than the stop transfer instructions to give effect to Section 4(a) hereof, it
will give its transfer agent no

<PAGE>

instructions inconsistent with instructions to issue Common Stock from time to
time upon conversion of the Debentures in such amounts as specified from time to
time by the Company to the transfer agent, bearing the restrictive legend
specified in Section 4(b) of this Agreement prior to registration of the Shares
under the 1933 Act, registered in the name of the Lender or its nominee and in
such denominations to be specified by the Holder in connection with each
conversion of the Debentures. Except as so provided, the Shares shall otherwise
be freely transferable on the books and records of the Company as and to the
extent provided in this Agreement and the other Transaction Agreements. Nothing
in this Section shall affect in any way the Lender's obligations and agreement
to comply with all applicable securities laws upon resale of the Securities. If
the Lender provides the Company with an opinion of counsel reasonably
satisfactory to the Company that registration of a resale by the Lender of any
of the Securities in accordance with clause (1)(B) of Section 4(a) of this
Agreement is not required under the 1933 Act, the Company shall (except as
provided in clause (2) of Section 4(a) of this Agreement) permit the transfer of
the Securities and, in the case of the Conversion Shares or of the Warrant
Shares, promptly instruct the Company's transfer agent to issue one or more
certificates for Common Stock without legend in such name and in such
denominations as specified by the Lender.

          B.   Subject to the provisions of this Agreement, the Company will
permit the Lender to exercise its right to convert the Debentures in the manner
contemplated by the Debentures and to exercise the Warrants in the manner
contemplated by the Warrants.

          C.   The Company understands that a delay in the issuance of the
Shares of Common Stock beyond the Delivery Date (as defined in the Debentures)
could result in economic loss to the Lender. As compensation to the Lender for
such loss, the Company agrees to pay late payments to the Lender for late
issuance of Shares upon conversion in accordance with the following schedule
(where "No. Business Days Late" refers to the number of business days which is
beyond two (2) business days after the Delivery Date):1

                   [Balance of page intentionally left blank]

--------------------
1 Example: Notice of Conversion is delivered on Monday, December 1, 2003. The
Delivery Date would be Thursday, December 4 (the third business day after such
delivery). If the certificate is delivered by Monday December 8 (2 business days
after the Delivery Date), no payment under this provision is due. If the
certificates are delivered on December 9, that is 1 "Business Day Late" in the
table below; if delivered on December 16, that 6 "Business Days Late" in the
table.

<PAGE>

                                   Late Payment For Each $10,000
                                of Debenture Principal or Interest
     No. Business Days Late           Amount Being Converted
     -------------------------------------------------------

               1                               $100
               2                               $200
               3                               $300
               4                               $400
               5                               $500
               6                               $600
               7                               $700
               8                               $800
               9                               $900
               10                              $1,000
               >10                             $1,000 + $200 for each Business
                                               Day Late beyond 10 days

The Company shall pay any payments incurred under this Section in immediately
available funds upon demand as the Lender's exclusive remedy (other than the
following provisions of this Section 5(c) and the provisions of the immediately
following Section 5(d) of this Agreement) for such delay. Furthermore, in
addition to any other remedies which may be available to the Lender, in the
event that the Company fails for any reason to effect delivery of such shares of
Common Stock by close of business on the Delivery Date, the Lender will be
entitled to revoke the relevant Notice of Conversion by delivering a notice to
such effect to the Company, whereupon the Company and the Lender shall each be
restored to their respective positions immediately prior to delivery of such
Notice of Conversion; provided, however, that an amount equal to any payments
contemplated by this Section 5(c) which have accrued through the date of such
revocation notice shall remain due and owing to the Converting Holder
notwithstanding such revocation. Anything in the foregoing provisions of this
paragraph (c) to the contrary notwithstanding, the total amount payable by the
Company under this paragraph (c) shall be reduced by an amount equal to fifty
percent (50%) of any Buy-In Adjustment Amount (as defined below) actually paid
by the Company to the Holder (but not by more than the total amount due without
regard to the provisions of this sentence).

          D.   If, by the relevant Delivery Date, the Company fails for any
reason to deliver the Shares to be issued upon conversion of a Debenture and
after such Delivery Date, the Holder of the Debentures being converted (a
"Converting Holder") purchases, in an arm's-length open market transaction or
otherwise, shares of Common Stock (the "Covering Shares") in order to make
delivery in satisfaction of a sale of Common Stock by the Converting Holder (the
"Sold Shares"), which delivery such Converting Holder anticipated to make using
the Shares to be issued upon such conversion (a "Buy-In"), the Converting Holder
shall have the right, to require the Company to pay to the Converting Holder, in
addition to and not in lieu of the amounts due under Section 5(c) hereof (but in
addition to all other amounts contemplated in

<PAGE>

other provisions of the Transaction Agreements, and not in lieu of any such
other amounts), the Buy-In Adjustment Amount (as defined below). The "Buy-In
Adjustment Amount" is the amount equal to the excess, if any, of (x) the
Converting Holder's total purchase price (including brokerage commissions, if
any) for the Covering Shares over (y) the net proceeds (after brokerage
commissions, if any) received by the Converting Holder from the sale of the Sold
Shares. The Company shall pay the Buy-In Adjustment Amount to the Company in
immediately available funds immediately upon demand by the Converting Holder. By
way of illustration and not in limitation of the foregoing, if the Converting
Holder purchases shares of Common Stock having a total purchase price (including
brokerage commissions) of $11,000 to cover a Buy-In with respect to shares of
Common Stock it sold for net proceeds of $10,000, the Buy-In Adjustment Amount
which Company will be required to pay to the Converting Holder will be $1,000.

          E.   In lieu of delivering physical certificates representing the
Common Stock issuable upon conversion, provided the Company's transfer agent is
participating in the Depository Trust Company ("DTC") Fast Automated Securities
Transfer program, upon request of the Holder and its compliance with the
provisions contained in this paragraph, so long as the certificates therefor do
not bear a legend and the Holder thereof is not obligated to return such
certificate for the placement of a legend thereon, the Company shall use its
best efforts to cause its transfer agent to electronically transmit the Common
Stock issuable upon conversion to the Holder by crediting the account of
Holder's Prime Broker with DTC through its Deposit Withdrawal Agent Commission
system.

          F.   The holder of any Debentures shall be entitled to exercise its
conversion privilege with respect to the Debentures notwithstanding the
commencement of any case under 11 U.S.C. ss.101 ET SEQ. (the "Bankruptcy Code").
In the event the Company is a debtor under the Bankruptcy Code, the Company
hereby waives, to the fullest extent permitted, any rights to relief it may have
under 11 U.S.C. ss.362 in respect of such holder's conversion privilege. The
Company hereby waives, to the fullest extent permitted, any rights to relief it
may have under 11 U.S.C. ss.362 in respect of the conversion of the Debentures.
The Company agrees, without cost or expense to such holder, to take or to
consent to any and all action necessary to effectuate relief under 11 U.S.C.
ss.362.

          G.   The Company will authorize its transfer agent to give information
relating to the Company directly to the Lender or the Lender's representatives
upon the request of the Lender or any such representative, to the extent such
information relates to (i) the status of shares of Common Stock issued or
claimed to be issued to the Lender in connection with a Notice of Conversion or
a Notice of Exercise, or (ii) the number of outstanding shares of Common Stock
of all shareholders as of a current or other specified date. At the request of
the Lender, the Company will provide the Lender with a copy of the authorization
so given to the transfer agent.

<PAGE>

          6.   CLOSING DATE.

          A.   The Closing Date shall occur on the date which is the first

          B.   The closing of the purchase and issuance of Debentures and
Warrants shall occur on the Closing Date at the offices of the Escrow Agent and

other time as is mutually agreed upon by the Company and the Finder.

          C.   Notwithstanding anything to the contrary contained herein, the
Escrow Agent will be authorized to release the Escrow Funds to the Company and
to others and to release the other Escrow Property on the Closing Date upon

provided in the Joint Escrow Instructions.

          7.   CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL.

Debentures and Warrants to the Lender pursuant to this Agreement on the Closing

          B,   Delivery by the Lender to the Escrow Agent of good funds as

accordance with this Agreement;

          C.   The accuracy on such Closing Date of the representations and
warranties of the Lender contained in this Agreement, each as if made on such
date, and the performance by the Lender on or before such date of all covenants
and agreements of the Lender required to be performed on or before such date;
and

          D.   There shall not be in effect any law, rule or regulation
prohibiting or restricting the transactions contemplated hereby, or requiring
any consent or approval which shall not have been obtained.

          8.   CONDITIONS TO THE LENDER'S OBLIGATION TO PURCHASE.

          The Company understands that the Lender's obligation to purchase the
Debentures and Warrants on the Closing Date is conditioned upon:

Transaction Agreements by the Company;

<PAGE>

in accordance with this Agreement;

          C.   The accuracy in all material respects on the Closing Date of the
representations and warranties of the Company contained in this Agreement, each
as if made on such date, and the performance by the Company on or before such
date of all covenants and agreements of the Company required to be performed on
or before such date;

          E.   On the Closing Date, the Lender shall have received an opinion of
counsel for the Company, dated the Closing Date, in form, scope and substance
reasonably satisfactory to the Lender, substantially to the effect set forth in
ANNEX III attached hereto;

          F.   There shall not be in effect any law, rule or regulation
prohibiting or restricting the transactions contemplated hereby, or requiring
any consent or approval which shall not have been obtained; and

          G.   From and after the date hereof to and including the Closing Date,
each of the following conditions will remain in effect: (i) the trading of the
Common Stock shall not have been suspended by the SEC or on the Principal
Trading Market; (ii) trading in securities generally on the Principal Trading
Market shall not have been suspended or limited; (iii), no minimum prices shall
been established for securities traded on the Principal Trading Market; and (iv)
there shall not have been any material adverse change in any financial market
that, in the reasonable judgment of the Lender, makes it impracticable or
inadvisable to purchase the Securities.

          9.   JURY TRIAL WAIVER. The Company and the Lender hereby waive a
trial by jury in any action, proceeding or counterclaim brought by either of the
Parties hereto against the other in respect of any matter arising out or in
connection with the Transaction Agreements.

          10.  GOVERNING LAW: MISCELLANEOUS.

          A.   This Agreement shall be governed by and interpreted in accordance
with the laws of the State of Delaware for contracts to be wholly performed in
such state and without giving effect to the principles thereof regarding the
conflict of laws. Each of the parties consents to the exclusive jurisdiction of
the federal courts whose districts encompass any part of the City of Wilmington
or the state courts of the State of Delaware sitting in the City of Wilmington
in connection with any dispute arising under this Agreement or any of the other
Transaction Agreements 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. To the extent
determined by such court, the Company shall reimburse the Lender for any
reasonable legal fees and disbursements incurred by the Lender in enforcement of
or protection of any of its rights under any of the Transaction Agreements.

<PAGE>

          B.   Failure of any party to exercise any right or remedy under this
Agreement or otherwise, or delay by a party in exercising such right or remedy,
shall not operate as a waiver thereof.

          C.   This Agreement shall inure to the benefit of and be binding upon
the successors and assigns of each of the parties hereto.

          D.   All pronouns and any variations thereof refer to the masculine,

agreement between the Company and such Lender, except that each Lender
acknowledges and consents to the rights granted to each other Lender [each, an

Agreement in accordance with and in reliance upon the exemption from securities
registration for offers and sales to accredited investors afforded, INTER ALIA,
by Rule 506 under Regulation D ("Regulation D") as promulgated by the United
States Securities and Exchange Commission (the "SEC") under the Securities Act
of 1933, as amended (the "1933 Act"), and/or Section 4(2) of the 1933 Act; and

          WHEREAS, the Lender wishes to lend funds to the Company, subject to
and upon the terms and conditions of this Agreement and acceptance of this
Agreement by the Company, the repayment of which will be represented by 6%
Convertible Debentures Series 03-2 of the Company (the "Convertible

together with the Warrants (as defined below) exercisable for the purchase of

          NOW THEREFORE, in consideration of the premises and the mutual

          2.   LENDER REPRESENTATIONS, WARRANTIES, ETC.; ACCESS TO INFORMATION;
INDEPENDENT INVESTIGATION.

          The Lender represents and warrants to, and covenants and agrees with,
the Company as follows:

          A.   Without limiting Lender's right to sell the Securities pursuant
to an effective registration statement or otherwise in compliance with the 1933
Act, the Lender is purchasing the Securities for its own account for investment
only and not with a view towards the public sale or distribution thereof and not
with a view to or for sale in connection with any distribution thereof.

          B.   The Lender is (i) an "accredited investor" as that term is
defined in Rule 501 of the General Rules and Regulations under the 1933 Act by
reason of Rule 501(a)(3), (ii) experienced in making investments of the kind
described in this Agreement and the related documents, (iii) able, by reason of
the business and financial experience of its officers (if an entity) and
professional advisors (who are not affiliated with or compensated in any way by
the Company or any of its Affiliates or selling agents), to protect its own
interests in connection with

<PAGE>

the transactions described in this Agreement, and the related documents, and to
evaluate the merits and risks of an investment in the Securities, and (iv) able
to afford the entire loss of its investment in the Securities.

          C.   All subsequent offers and sales of the Securities by the Lender
shall be made pursuant to registration of the relevant Securities under the 1933
Act or pursuant to an exemption from registration.

          D.   The Lender understands that the Securities are being offered and
sold to it in reliance on specific exemptions from the registration requirements
of the 1933 Act and state securities laws and that the Company is relying upon
the truth and accuracy of, and the Lender's compliance with, the
representations, warranties, agreements, acknowledgments and understandings of
the Lender set forth herein in order to determine the availability of such
exemptions and the eligibility of the Lender to acquire the Securities.

          E.   The Lender and its advisors, if any, have been furnished with or
have been given access to all materials relating to the business, finances and
operations of the Company and materials relating to the offer and sale of the
Debentures and the Warrants which have been requested by the Lender, including
those set forth on in any annex attached hereto. The Lender and its advisors, if
any, have been afforded the opportunity to ask questions of the Company and its
management and have received complete and satisfactory answers to any such
inquiries. Without limiting the generality of the foregoing, the Lender has also
had the opportunity to obtain and to review the Company's filings on EDGAR
listed on ANNEX VI hereto (the documents listed on such Annex VI, to the extent
available on EDGAR or otherwise provided to the Lender as indicated on said
Annex VI, collectively, the "Company's SEC Documents").

          F.   The Lender understands that its investment in the Securities
involves a high degree of risk and has reviewed the material under the caption
"Risk Factors" contained in the Company's Annual Report on Form 10-KSB for the
fiscal year ended December 31, 2002 listed on Annex VI.

          G.   The Lender hereby represents that, in connection with its
purchase of the Securities, it has not relied on any statement or representation
by the Company or the Finder or any of their respective officers, directors and
employees or any of their respective attorneys or agents or the Finder, except
as specifically set forth herein. The Finder is a third party beneficiary of
this provision.

          H.   The Lender 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.

          I.   This Agreement and the other Transaction Agreements to which the
Lender is a party, and the transactions contemplated thereby, have been duly and
validly authorized, executed and delivered on behalf of the Lender and are valid
and binding agreements

<PAGE>

of the Lender enforceable in accordance with their respective terms, subject as
to enforceability to general principles of equity and to bankruptcy, insolvency,
moratorium and other similar laws affecting the enforcement of creditors' rights
generally.

          3.   COMPANY REPRESENTATIONS, ETC. The Company represents and warrants
to the Lender as of the Initial Closing Date that, except as otherwise provided
in the DISCLOSURE LETTER hereto or in the Company's SEC Documents:

          A.   RIGHTS OF OTHERS AFFECTING THE TRANSACTIONS. There are no
preemptive rights of any shareholder of the Company, as such, to acquire the
Debentures, the Warrants or the Shares. No party has a currently exercisable
right of first refusal which would be applicable to any or all of the
transactions contemplated by the Transaction Agreements.

          B.   STATUS. The Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of Incorporation and
has the requisite corporate power to own its properties and to carry on its
business as now being conducted. The Company is duly qualified as a foreign
corporation to do business and is in good standing in each jurisdiction where
the nature of the business conducted or property owned by it makes such
qualification necessary, other than those jurisdictions in which the failure to
so qualify would not have or result in a Material Adverse Effect. The Company
has registered its stock and is obligated to file reports pursuant to Section 12
or Section 15(d) of the Securities and Exchange Act of 1934, as amended (the
"1934 Act"). The Common Stock is listed and quoted on the Principal Trading
Market. The Company has received no notice, either oral or written, with respect
to the continued eligibility of the Common Stock for such listing and quotation
on the Principal Trading Market, and the Company has maintained all requirements
on its part for the continuation of such listing and quotation.

          C.   AUTHORIZED SHARES. The authorized capital stock of the Company
consists of (i) 200,000,000 shares of Common Stock, $.001 par value per share,
of which approximately 76,318,772 are outstanding, and (ii) 5,000,000 shares of
Convertible Preferred Stock, $.001 par value per share, of which none are
outstanding as of the date hereof. All issued and outstanding shares of Common
Stock have been duly authorized and validly issued and are fully paid and
non-assessable. The Company has sufficient authorized and unissued shares of
Common Stock as may be necessary to effect the issuance of the Shares. As of the
Initial Closing Date, the Shares shall have been duly authorized by all
necessary corporate action on the part of the Company, and, when issued on the
conversion of, or as interest on, the Debentures in accordance with their terms
or upon exercise of the Warrants in accordance with their terms, will be duly
and validly issued, fully paid and non-assessable and will not subject the
Holder thereof to personal liability by reason of being such Holder.

          D.   TRANSACTION AGREEMENTS AND STOCK. This Agreement and each of the
other Transaction Agreements, and the transactions contemplated thereby, have
been duly and validly authorized by the Company, this Agreement has been duly
executed and delivered by the Company and this Agreement is, and the Debentures,
the Warrants and each of the other

<PAGE>

Transaction Agreements, when executed and delivered by the Company, will be,
valid and binding agreements of the Company enforceable in accordance with their
respective terms, subject as to enforceability to general principles of equity
and to bankruptcy, insolvency, moratorium, and other similar laws affecting the
enforcement of creditors' rights generally.

          E.   NON-CONTRAVENTION. The execution and delivery of this Agreement
and each of the other Transaction Agreements by the Company, the issuance of the
Securities, and the consummation by the Company of the other transactions
contemplated by this Agreement, the Debentures, the Warrants and the other
Transaction Agreements do not and will not conflict with or result in a breach
by the Company of any of the terms or provisions of, or constitute a default
under (i) the certificate of incorporation or by-laws of the Company, each as
currently in effect, (ii) any indenture, mortgage, deed of trust, or other
material agreement or instrument to which the Company is a party or by which it
or any of its properties or assets are bound, including any listing agreement
for the Common Stock except as herein set forth, or (iii) to its knowledge, any
existing applicable law, rule, or regulation or any applicable decree, judgment,
or order of any court, United States federal or state regulatory body,
administrative agency, or other governmental body having jurisdiction over the
Company or any of its properties or assets, except such conflict, breach or
default which would not have or result in a Material Adverse Effect.

          F.   FILINGS. None of the Company's SEC Documents contained, at the
time they were filed, any untrue statement of a material fact or omitted to
state any material fact required to be stated therein or necessary to make the
statements made therein in light of the circumstances under which they were

requisite forms, reports and exhibits thereto required to be filed by the
Company with the SEC.

          G.   ABSENCE OF CERTAIN CHANGES. Since the Last Audited Date, there
has been no material adverse change and no Material Adverse Effect, except as
disclosed in the Company's SEC Documents. Since the Last Audited Date, except as

any material obligation or liability (absolute or contingent), other than

          H.   FULL DISCLOSURE. To the best of the Company's knowledge, there is
no fact known to the Company (other than general economic conditions known to
the public generally or as disclosed in the Company's SEC Documents) that has
not been disclosed in writing to the Lender that would reasonably be expected to
have or result in a Material Adverse Effect.

          I.   ABSENCE OF LITIGATION. There is no action, suit, proceeding,
inquiry or investigation before or by any court, public board or body pending
or, to the knowledge of the Company, threatened against or affecting the Company
before or by any governmental authority or nongovernmental department,
commission, board, bureau, agency or instrumentality or any other person,
wherein an unfavorable decision, ruling or finding would have a Material Adverse
Effect or which would adversely affect the validity or enforceability of, or the
authority or ability of the Company to perform its obligations under, any of the
Transaction Agreements. The Company is not aware of any valid basis for any such
claim that (either individually or in the aggregate with all other such events
and circumstances) could reasonably be expected to have a Material Adverse
Effect. There are no outstanding or unsatisfied judgments, orders, decrees,
writs, injunctions or stipulations to which the Company is a party or by which
it or any of its properties is bound, that involve the transaction contemplated
herein or that, alone or in the aggregate, could reasonably be expect to have a
Material Adverse Effect.

          J.   ABSENCE OF EVENTS OF DEFAULT. Except as set forth in Section 3(e)
hereof, no Event of Default (or its equivalent term), as defined in the
respective agreement to which the Company is a party, and no event which, with
the giving of notice or the passage of time or both, would become an Event of
Default (or its equivalent term) (as so defined in such agreement), has occurred
and is continuing, which would have a Material Adverse Effect.

          K.   ABSENCE OF CERTAIN COMPANY CONTROL PERSON ACTIONS OR EVENTS.

the best of the Company's knowledge, none of the following has occurred during
the past five (5) years with respect to a Company Control Person:

     Control Person, or any partnership in which he was a general partner at or
     within two years before the time of such filing, or any corporation or
     business association of which he was an executive officer at or within two
     years before the time of such filing;

     (2) Such Company Control Person was convicted in a criminal proceeding or
     is a named subject of a pending criminal proceeding (excluding traffic
     violations and other minor offenses);

<PAGE>

     (3) Such Company Control Person was the subject of any order, judgment or
     decree, not subsequently reversed, suspended or vacated, of any court of
     competent jurisdiction, permanently or temporarily enjoining him from, or
     otherwise limiting, the following activities:

               (i) acting, as an investment advisor, underwriter, broker or
               dealer in securities, or as an affiliated person, director or
               employee of any investment company, bank, savings and loan
               association or insurance company, as a futures commission
               merchant, introducing broker, commodity trading advisor,
               commodity pool operator, floor broker, any other Person regulated
               by the Commodity Futures Trading Commission ("CFTC") or engaging
               in or continuing any conduct or practice in connection with such
               activity;

               (ii) engaging in any type of business practice; or (iii) engaging
               in any activity in connection with the purchase or sale of any

               federal or state securities laws or federal commodities laws;

     (4) Such Company Control Person was the subject of any order, judgment or
     decree, not subsequently reversed, suspended or vacated, of any federal or
     state authority barring, suspending or otherwise limiting for more than 60
     days the right of such Company Control Person to engage in any activity
     described in paragraph (3) of this item, or to be associated with Persons
     engaged in any such activity; or

     (5) Such Company Control Person was found by a court of competent
     jurisdiction in a civil action or by the CFTC or SEC to have violated any
     federal or state securities law, and the judgment in such civil action or
     finding by the CFTC or SEC has not been subsequently reversed, suspended,
     or vacated.

          L.   NO UNDISCLOSED LIABILITIES OR EVENTS. To the best of the
Company's knowledge, the Company has no liabilities or obligations other than
those disclosed in the Transaction Agreements or the Company's SEC Documents or
those incurred in the ordinary course of the Company's business since the Last
Audited Date, or which individually or in the aggregate, do not or would not
have a Material Adverse Effect. No event or circumstances has occurred or exists
with respect to the Company or its properties, business, operations, condition
(financial or otherwise), or results of operations, which, under applicable law,
rule or regulation, requires public disclosure or announcement prior to the date
hereof by the Company but which has not been so publicly announced or disclosed.
There are no proposals currently under consideration or currently anticipated to
be under consideration by the Board of Directors or the executive officers of
the Company which proposal would (x) change the certificate of incorporation or
other charter document or by-laws of the Company, each as currently in effect,

<PAGE>

with or without shareholder approval, which change would reduce or otherwise
adversely affect the rights and powers of the shareholders of the Common Stock
or (y) materially or substantially change the business, assets or capital of the
Company, including its interests in subsidiaries.

          M.   NO DEFAULT. Neither the Company nor any of its subsidiaries is in
default in the performance or observance of any material obligation, agreement,
covenant or condition contained in any material indenture, mortgage, deed of
trust or other material instrument or agreement to which it is a party or by
which it or its property is bound.

          N.   NO INTEGRATED OFFERING. Neither the Company nor any of its
Affiliates nor any Person acting on its or their behalf has, directly or
indirectly, at any time since March 1, 2003, made any offer or sales of any
security or solicited any offers to buy any security under circumstances that
would eliminate the availability of the exemption from registration under
Regulation D in connection with the offer and sale of the Securities as
contemplated hereby.

          O.   DILUTION. The number of shares issuable on conversion of the
Debentures and upon exercise of the Warrants may have a dilutive effect on the
ownership interests of the other shareholders (and Persons having the right to
become shareholders) of the Company. The Company's executive officers and
directors have studied and fully understand the nature of the Securities being
sold hereby and recognize that they have such a potential dilutive effect. The
board of directors of the Company has concluded, in its good faith business
judgment, that such issuance is in the best interests of the Company. The
Company specifically acknowledges that its obligation to issue the Conversion
Shares upon conversion of the Debentures and the Warrant Shares upon exercise of
the Warrants is binding upon the Company and enforceable regardless of the
dilution such issuance may have on the ownership interests of other shareholders
of the Company, and the Company will honor such obligations, including honoring
every Notice of Conversion (as contemplated by the Debentures) and every Notice
of Exercise (as contemplated by the Warrants), unless the Company is subject to
an injunction (which injunction was not sought by the Company) prohibiting the
Company from doing so.

          P.   FEES TO BROKERS, FINDERS AND OTHERS. Except for payment of the
fees to the Finder's Compensation (as defined below) to the Finder, payment of
which is the sole responsibility of the Company, the Company has taken no action
which would give rise to any claim by any Person for brokerage commission,
finder's fees or similar payments by Lender relating to this Agreement or the
transactions contemplated hereby. Lender shall have no obligation with respect
to such fees or with respect to any claims made by or on behalf of other Persons
for fees of a type contemplated in this paragraph that may be due in connection
with the transactions contemplated hereby. The Company shall indemnify and hold
harmless each of Lender, its employees, officers, directors, agents, and
partners, and their respective Affiliates, from and against all claims, losses,
damages, costs (including the costs of preparation and attorney's fees) and
expenses suffered in respect of any such claimed or existing fees, as and when
incurred. The term "Finder's Compensation" means, in connection with the
consummation of the transactions contemplated by this Agreement, (1) a cash fee
and expense allowance in the amount contemplated by the Joint Escrow
Instructions, (2) a cash fee equal to ten percent (10%)

<PAGE>

of the Exercise Price (as defined in the Warrant) paid by a Holder upon exercise
of a Warrant, and (3) warrants to purchase Common Stock for a number of shares
equal to ten percent (10%) of the Warrant Shares for all Lenders.

          Q.   CONFIRMATION. The Company confirms that all statements of the
Company contained herein shall survive acceptance of this Agreement by the
Lender. The Company agrees that, if any events occur or circumstances exist
prior to the relevant Closing Date or the release of the relevant Purchase Price
to the Company which would make any of the Company's representations,
warranties, agreements or other information set forth herein materially untrue
or materially inaccurate as of such date, the Company shall immediately notify
the Lender (directly or through its counsel, if any) and the Escrow Agent in
writing prior to such date of such fact, specifying which representation,
warranty or covenant is affected and the reasons therefor.

          4.   CERTAIN COVENANTS AND ACKNOWLEDGMENTS.

          A.   TRANSFER RESTRICTIONS.

          (i)  The Lender acknowledges that (1) the Securities have not been and
are not being registered under the provisions of the 1933 Act and, except as
provided in the Registration Rights Agreement or otherwise included in an
effective registration statement, the Shares have not been and are not being
registered under the 1933 Act, and may not be transferred unless (A)
subsequently registered thereunder or (B) the Lender shall have delivered to the
Company an opinion of counsel, reasonably satisfactory in form, scope and
substance to the Company, to the effect that the Securities to be sold or
transferred may be sold or transferred pursuant to an exemption from such
registration; (2) any sale of the Securities made in reliance on Rule 144
promulgated under the 1933 Act may be made only in accordance with the terms of
said Rule and further, if said Rule is not applicable, any resale of such
Securities under circumstances in which the seller, or the Person through whom
the sale is made, may be deemed to be an underwriter, as that term is used in
the 1933 Act, may require compliance with some other exemption under the 1933
Act or the rules and regulations of the SEC thereunder; and (3) neither the
Company nor any other Person is under any obligation to register the Securities
(other than pursuant to the Registration Rights Agreement) under the 1933 Act or
to comply with the terms and conditions of any exemption thereunder.

          (ii) In addition to the foregoing, and not in lieu thereof, the Lender
agrees that, without the express written consent of the Company in each
instance, it will not transfer a Debenture or a Warrant to any Person which is
known to be (i) in the same business as the Company, (ii) a utility or other
provider of electric service, (iii) an internet service provider or other
provider of broadband services, or (iv) any subsidiary or affiliate of the
either of the foregoing.

          B.   RESTRICTIVE LEGEND. The Lender acknowledges and agrees that,
until such time as the relevant Shares have been registered under the 1933 Act,
as contemplated by the

<PAGE>

Registration Rights Agreement and sold in accordance with an effective
Registration Statement or otherwise in accordance with another effective
registration statement, the certificates and other instruments representing any
of the Securities shall bear a restrictive legend in substantially the following
form (and a stop-transfer order may be placed against transfer of any such
Securities):

     THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
     AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD OR
     OFFERED FOR SALE IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR
     THE SECURITIES OR AN OPINION OF COUNSEL OR OTHER EVIDENCE ACCEPTABLE TO THE
     COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

          C.   FILINGS. The Company undertakes and agrees to make all necessary
filings in connection with the sale of the Securities to the Lender under any
United States laws and regulations applicable to the Company, or by any domestic
securities exchange or trading market, and to provide a copy thereof to the
Lender promptly after such filing.

          D.   REPORTING STATUS. So long as the Lender beneficially owns any of
the Securities, the Company shall file all reports required to be filed with the
SEC pursuant to Section 13 or 15(d) of the 1934 Act, shall take all reasonable
action under its control to ensure that adequate current public information with
respect to the Company, as required in accordance with Rule 144(c)(2) of the
1933 Act, is publicly available, and shall not terminate its status as an issuer
required to file reports under the 1934 Act even if the 1934 Act or the rules
and regulations thereunder would permit such termination. The Company will take
all reasonable action under its control to maintain the continued listing and
quotation and trading of its Common Stock (including, without limitation, all
Registrable Securities) on the Principal Trading Market or a listing on the
NASDAQ/Small Cap or National Markets and, to the extent applicable to it, will
comply in all material respects with the Company's reporting, filing and other
obligations under the by-laws or rules of the Principal Trading Market and/or
the National Association of Securities Dealers, Inc., as the case may be,
applicable to it at least through the date which is sixty (60) days after the
later of the date on which (x) all of the Debentures have been converted or been
paid in full or (y) all of the Warrants have been exercised or have expired.

          E.   USE OF PROCEEDS. The Company will use the proceeds received
hereunder (excluding amounts paid by the Company for Finder's Compensation in
connection with the sale of the Securities or legal and escrow fees contemplated
by the Joint Escrow Instructions) (i) first, to the satisfaction in full of the
outstanding obligations, if any, under that certain $400,000 6% Convertible
Debenture Series 03-1 Due October 31, 2003 originally issued by the Company on
or about September 8, 2003 (the "Series 03-1 Debenture"), and (ii) then, for
general corporate purposes.

<PAGE>

          F.   WARRANTS. The Company agrees to issue to the Lender on each
Closing Date transferable warrants (the "Warrants"), with cashless exercise
rights (subject to certain conditions provided in the Warrants), for the
purchase of one (1) share of Common Stock for each two (2) Issue Date Conversion
Shares (as defined below). The exercise price of the Warrants will be equal to
$0.25, subject to adjustment as provided in the Warrant. The Warrants will
expire on the last day of the calendar month in which the third annual
anniversary of the relevant Closing Date occurs, subject to earlier expiration
as provided in the Warrants. Each of the Warrants shall be in the form annexed
hereto as ANNEX V. The Warrant Shares shall be subject to the provisions of the
Registration Rights Agreement. The term "Issue Date Conversion Share" means the
number of shares of Common Stock equal to (x) the Purchase Price for the
relevant Closing Date, divided by (y) the Conversion Price in effect on such
Closing Date.

          G.   CERTAIN AGREEMENTS.

          (i)  The Company covenants and agrees that, except for the sale of
Debentures and Warrants to the Other Lenders and subject to the other provisions
of this Section 4(g), during the period (the "New Transaction Period") from the
Initial Closing Date and continuing through and including the Final Lock-up Date
(as defined below), it will not, without the prior written consent of a Majority
in Interest of the Holders in each instance, enter into any subsequent or
further offer or sale of Common Stock or securities convertible into and/or
other rights exercisable for the issuance of Common Stock (collectively, "New
Common Stock") to or with any third party (any such offer or sale of New Common
Stock, a "New Transaction"). The term "Final Lock-up Date" means the date which
is the one hundred thirty-five (135) days after the Effective Date, but not
counting for such purposes the days, if any, during which sale of Registrable
Securities was suspended after the Effective Date.1

          (ii) In the event there is a New Transaction which breaches the
provisions of this Section 4(g) (it being understood by the parties that a
Specified New Transaction or an Excluded New Transaction, as those terms are
defined below, does not constitute such a breach),

     (A)  the Conversion Price on any Unconverted Debenture (as defined in the
     Debenture) or on any Additional Debenture to be issued on a later date
     shall be adjusted to an amount (the "Adjusted Conversion Price") equal to
     the lowest of (1) ninety percent (90%) of the then existing Conversion
     Price, or (2) eighty percent (80%) of the of the lower of (X) the lowest
     fixed purchase price of any shares of the New Common Stock contemplated in
     the New Transaction or (Y) the lowest conversion price which would be
     applicable under the terms of the New Transaction;

--------------------
1 By way of illustration: If the sale of Registrable Securities was suspended
for ten (10) days in the interim, the applicable Final Lock-up Date will be one
hundred forty-five (145) days after the Effective Date. If on the 138th day
after the Effective Date, the sale of Registrable Securities was suspended again
for five (5) days, the Final Lock-up Date will be one hundred fifty (150) days
after the Effective Date.

<PAGE>

     (B)  with respect to all portions of the principal and interest of any
     Debenture converted prior to such date (or converted before the adjustment
     referred to in the immediately preceding subparagraph (A) is effected), the
     Company will issue to the Holder additional shares of Common Stock
     ("Additional Shares") equal to the excess, if any, of (1) (X) the aggregate
     amount of the principal and accrued interest of the Debenture so converted,
     divided by (Y) the Adjusted Conversion Price, over (2) the number of
     Conversion Shares and Additional Shares, if any, previously issued in
     connection with such conversion;

     (C)  if the provisions of the debenture or similar instrument (howsoever
     denominated), if any, of the New Transaction are more beneficial to the
     holder of such instrument than the corresponding terms of the Debenture,2
     or if the terms which are beneficial to the Company in the Debenture are
     not included in the corresponding instrument in the New Transaction,3 then,
     unless waived by the Holder, the Debenture terms shall be modified to
     reflect similar terms (based on the original issue date of the Debentures);

     (D)  the number of Warrants issued or be issued on a subsequent date shall
     be adjusted to equal the higher of (1) the number of Warrant Shares
     originally contemplated by this Agreement or (2) the number of shares equal
     to fifty percent (50%) of (I) the Purchase Price divided by (II) the lower
     of (x) the Bid Price for the Trading Day immediately preceding the initial
     closing date of the New Transaction or (y) Adjusted Conversion Price for
     the initial closing date of the New Transaction; and

     (E)  the Exercise Price on the Warrants shall be adjusted to equal the
     lowest of (1) the then existing Warrant Price, (2) the lowest Warrant Price
     applicable to the New Transaction, or (3) twice the Adjusted Conversion
     Price;

     (F)  if the provisions of the warrant, option or similar instrument
     (howsoever denominated), if any, of the New Transaction are more beneficial
     to the holder of such instrument than the corresponding terms of the
     Warrant, 4 or if the terms which are beneficial to the Company in the
     Debenture are not included in the corresponding instrument in the New
     Transaction,5 then, unless waived by the Holder, the Warrant terms shall be
     modified to reflect similar terms (based on the original issue date of the
     Warrants); and

--------------------
2 Without limiting the foregoing, by way of example: the maturity date of the
instrument in the Specified New Transaction is more than three years from its
original issue date .

3 Without limiting the foregoing, by way of example: the instrument does not
provide that the Company may redeem the instrument or give notice requiring a
mandatory conversion prior to the maturity date or does not provide for
mandatory conversion on the maturity date.

4 Without limiting the foregoing, by way of example: the expiration date of the
instrument in the New Transaction is more than three years from its original
issue date.

<PAGE>

     (G)  the Holder will have such other rights as are provided in the
     Debenture.

          (iii) Anything in the foregoing provisions of this Section 4(g) to the
contrary notwithstanding, during the New Transaction Period, the Lender hereby
gives the Lender's consent to the Company's entering into a New Transaction
which is a Permitted New Transaction (as defined below) or an Allowed New
Transaction (as defined below) during the New Transaction Period (and any
Permitted New Transaction or any Allowed New Transaction shall not be deemed a
breach of the provisions of this Section 4(g)), provided, however, that if there
is a Permitted New Transaction or an Allowed New Transaction (collectively,
"Specified New Transactions"):

     (A)  the Conversion Price on any Unconverted Debenture or any Additional
     Debenture to be issued at a subsequent date shall be adjusted to an amount
     (the "Alternative Conversion Price") equal to the lower of (1) the then
     existing Conversion Price, or (2) the lower of (X) the lowest fixed
     purchase price of any shares of the New Common Stock contemplated in the
     Specified New Transaction or (Y) the lowest conversion price which would be
     applicable under the terms of the Specified New Transaction;

     (B)  with respect to all portions of the principal and interest of any
     Debenture converted prior to such date (or converted before the adjustment
     referred to in the immediately preceding subparagraph (A) is effected), the
     Company will issue to the Holder additional shares of Common Stock
     ("Additional Shares") equal to the excess, if any, of (1) (X) the aggregate
     amount of the principal and accrued interest of the Debenture so converted,
     divided by (Y) the Alternative Conversion Price, over (2) the number of
     Conversion Shares, if any, previously issued in connection with such
     conversion;

     (C)  if the provisions of the debenture or similar instrument (howsoever
     denominated), if any, of the Specified New Transaction are more beneficial
     to the holder of such instrument than the corresponding terms of the
     Debenture,6 or if the terms which are beneficial to the Company in the
     Debenture are not included

--------------------
5 Without limiting the foregoing, by way of example: the instrument in the New
Transaction does not provide that the Company may accelerate the expiration date
of the instrument.

6 Without limiting the foregoing, by way of example: the maturity date of the
instrument in the Specified New Transaction is more than three years from its
original issue date or provides for cashless exercise rights for a period which
is longer than that contemplated by the Warrants.

<PAGE>

     in the corresponding instrument in the Specified New Transaction,7 then,
     unless waived by the Holder, the Debenture terms shall be modified to
     reflect similar terms (based on the original issue date of the Debentures);

     (D)  the number of Warrants shall be adjusted to equal the higher of (1)
     the number of Warrant Shares originally provided in the Warrants or (2) the
     number of shares equal to (x) (I) the higher of fifty percent (50%) or (II)
     the Alternative Warrant Percentage (as defined below) of (y) (I) the
     Purchase Price divided by (II) the Conversion Price or, if lower, the
     Alternative Conversion Price for the initial closing date of the Specified
     New Transaction;

     (E)  the Exercise Price on the Warrants shall be adjusted to equal the
     lower of (1) the then existing Warrant Price, or (2) the lowest Warrant
     Price applicable to the Specified New Transaction; and

     (F)  if the provisions of the warrant, option or similar instrument
     (howsoever denominated), if any, of the Specified New Transaction are more
     beneficial to the holder of such instrument than the corresponding terms of
     the Warrant, 8 or if the terms which are beneficial to the Company in the
     Debenture are not included in the corresponding instrument in the Specified
     New Transaction,9 then, unless waived by the Holder, the Warrant terms
     shall be modified to reflect similar terms (based on the original issue
     date of the Warrants).

          (iv) The term "Permitted New Transaction" means a New Transaction for
the sale of common stock or convertible debentures and warrants, subject to the
following terms, conditions and adjustments: (A) such offer and sale shall be
made only to accredited investors; (B) the maximum amount raised in such offer
and sale (before payment of fees and expenses) shall be $5,000,000 less the
Total Purchase Price.

          (v)  The term "Allowed New Transaction" means a New Transaction other
than a Permitted New Transaction, subject to the following terms, conditions and
adjustments: (A) such offer and sale shall be made only to accredited investors;
and (B) by the terms of such New Transaction a registration statement covering
the re-sale of the securities purchased in such New Transaction (or issuable on
conversion or exercise of securities issued in connection with

7 Without limiting the foregoing, by way of example: the instrument in the
Specified New Transaction does not provide that the Company may redeem the
instrument or give notice requiring a mandatory conversion prior to the maturity
date or does not provide for mandatory conversion on the maturity date.

8 Without limiting the foregoing, by way of example: the expiration date of the
instrument in the Specified New Transaction is more than three years from its
original issue date.

9 Without limiting the foregoing, by way of example: the instrument does not
provide that the Company may accelerate the expiration date of the instrument or
provides for cashless exercise rights for a period which is longer than that
contemplated by the Warrants.

<PAGE>

such New Transaction) may not be filed earlier than six (6) months after the
Effective Date;

          (vi)   The term "Alternative Warrant Percentage" means (x) the number
of shares which are eligible to be purchased under the warrant, option or other
right (howsoever denominated) issued in the New Transaction ("New Transaction
Warrants"), including any Specified New Transaction, divided by (y) the
aggregate of the shares of New Common Stock issued or issuable in such
transaction (excluding the shares issuable on exercise of the New Transaction
Warrants).

          (vii)  The foregoing provisions of Section 4(g) do not apply to the
issuance of New Common Stock (a) in connection with a Person's exercise of
conversion or other rights it may have under documents executed and transactions
consummated prior to the date of this Agreement, (b) pursuant to an Employee
Stock Option Plan (an "ESOP") of the Company, such ESOP having been properly
approved by the shareholders of the Company prior to the date of this Agreement,
(c) pursuant to a Non-Employee Directors' Stock Option Plan (a "NDSOP") of the
Company, provided that not more than 250,000 shares are issued under the NDSOP
for each 90-day calendar period and such NDSOP having been properly approved by
the shareholders of the Company prior to the date of this Agreement, or (d)
acquisitions of controlling interests in other corporations by the Company. Any
issuance contemplated by this subparagraph (vii) is referred to as an "Excluded
New Transaction."

          (viii) Nothing in the foregoing provisions reflects either an
obligation on the part of any Lender to participate in any New Transaction,
including any Specified New Transaction or a limitation on any Lender from
participating in any New Transaction, including any Specified New Transaction.
Nothing in this Agreement shall give any Lender a right of first refusal with
respect to any New Transaction, including any Specified New Transaction.

          (ix)   Any of the foregoing provisions of this Section 4(g) or any
other provision of this Agreement or any of the other Transaction Agreements to
the contrary notwithstanding, the Company shall not engage in any offers, sales
or other transactions of its securities which would adversely affect the
exemption from registration available for the transactions contemplated by the
Transaction Agreements.

          H.     AVAILABLE SHARES. The Company shall have at all times
authorized and reserved for issuance, free from preemptive rights, a number of
shares (the "Minimum Available Shares") at least equal to (x) one hundred
twenty-five percent (125%) of the number of shares of Common Stock issuable as
may be required to satisfy the conversion rights of the Holders of principal on
all outstanding Convertible Debentures plus (y) one hundred ten percent (110%)
of the number of shares issuable upon exercise of all outstanding Warrants held
by all Holders (in each case, whether such Convertible Debentures or Warrants
were originally issued to the Holder, the Lender or to any other party). For the
purposes of such calculations, the Company should assume that all Debentures,
including without limitation, the Additional Debentures, were then issued and
convertible and all Warrants, including without limitation the Additional
Warrants, were then issued and exercisable, in each case without regard to any
restrictions which

<PAGE>

might limit any Holder's right to convert any of the Debentures or to exercise
any of the Warrants held by any Holder.

          I.   PUBLICITY, FILINGS, RELEASES, ETC. Each of the parties agrees
that it will not disseminate any information relating to the Transaction
Agreements or the transactions contemplated thereby, including issuing any press
releases, holding any press conferences or other forums, or filing any reports
(collectively, "Publicity"), without giving the other party reasonable advance
notice and an opportunity to comment on the contents thereof. Neither party will
include in any such Publicity any statement or statements or other material to
which the other party reasonably objects. In furtherance of the foregoing, the
Company will provide to the Lender drafts of the applicable text of any filing
intended to be made with the SEC which refers to the Transaction Agreements or
the transactions contemplated thereby as soon as practicable (but at least three
(3) business days before such filing will be made) and will not include in such
filing any statement or statements or other material to which the other party
reasonably objects. Notwithstanding the foregoing, each of the parties hereby
consents to the inclusion of the text of the Transaction Agreements in filings
made with the SEC (but any descriptive text accompanying or part of such filing
shall be subject to the other provisions of this paragraph).

          J.   COMPANY PRINCIPAL AGREEMENTS. The Company hereby agrees that,
prior to the Initial Closing Date, the Company will cause each of the persons
named at the head of ANNEX VII attached hereto (each, a "Company Principal"),
each of whom is a director or a principal officer or employee of the Company,
and certain persons who are related to or controlled by such Company Principal,
to execute and deliver an agreement (each, a "Company Principal's Agreement")
regarding limitations on the sale or other disposition of such Company
Principal's shares of the Company's Common Stock (or instruments convertible
into or exercisable for such shares). Each Company Principal's Agreement shall
be substantially in the form set forth in ANNEX VII attached hereto.

          5.   TRANSFER AGENT INSTRUCTIONS.

          A.   The Company warrants that, with respect to the Securities, other
than the stop transfer instructions to give effect to Section 4(a) hereof, it
will give the Transfer Agent no instructions inconsistent with instructions to
issue Common Stock from time to time upon conversion of the Debentures in such
amounts as specified from time to time by the Company to the Transfer Agent,
bearing the restrictive legend specified in Section 4(b) of this Agreement prior
to registration of the Shares under the 1933 Act, registered in the name of the
Lender or its nominee and in such denominations to be specified by the Holder in
connection with each conversion of the Debentures. Except as so provided, the
Shares shall otherwise be freely transferable on the books and records of the
Company as and to the extent provided in this Agreement and the other
Transaction Agreements. Nothing in this Section shall affect in any way the
Lender's obligations and agreement to comply with all applicable securities laws
upon resale of the Securities. If the Lender provides the Company with an
opinion of counsel reasonably satisfactory to the Company that registration of a
resale by the Lender of any of the Securities in accordance with clause (1)(B)
of Section 4(a) of this Agreement is not required

<PAGE>

under the 1933 Act, the Company shall (except as provided in clause (2) of
Section 4(a) of this Agreement) permit the transfer of the Securities and, in
the case of the Conversion Shares or of the Warrant Shares, promptly instruct
the Transfer Agent to issue one or more certificates for Common Stock without
legend in such name and in such denominations as specified by the Lender.

          B.   Subject to the provisions of this Agreement, the Company will
permit the Lender to exercise its right to convert the Debentures in the manner
contemplated by the Debentures and to exercise the Warrants in the manner
contemplated by the Warrants.

          C.   The Company understands that a delay in the issuance of the
Shares of Common Stock beyond the Delivery Date (as defined in the Debentures)
could result in economic loss to the Lender. As compensation to the Lender for
such loss, the Company agrees to pay late payments to the Lender for late
issuance of Shares upon conversion in accordance with the following schedule
(where "No. Business Days Late" refers to the number of business days which is
beyond two (2) business days after the Delivery Date):10

                                    Late Payment For Each $10,000
                                 of Debenture Principal or Interest
     No. Business Days Late            Amount Being Converted
     --------------------------------------------------------

                1                               $100
                2                               $200
                3                               $300
                4                               $400
                5                               $500
                6                               $600
                7                               $700
                8                               $800
                9                               $900
                10                              $1,000
                >10                             $1,000 + $200 for each Business
                                                Day Late beyond 10 days

The Company shall pay any payments incurred under this Section in immediately
available funds upon demand as the Lender's exclusive remedy (other than the
following provisions of this Section 5(c) and the provisions of the immediately
following Section 5(d) of this Agreement) for

--------------------
10 Example: Notice of Conversion is delivered on Monday, December 1, 2003. The
Delivery Date would be Monday, December 8 (the fifth business day after such
delivery). If the certificate is delivered by Wednesday, December 10 (2 business
days after the Delivery Date), no payment under this provision is due. If the
certificates are delivered on December 11, that is 1 "Business Day Late" in the
table below; if delivered on December 18, that is 6 "Business Days Late" in the
table.

<PAGE>

such delay. Furthermore, in addition to any other remedies which may be
available to the Lender, in the event that the Company fails for any reason to
effect delivery of such shares of Common Stock by close of business on the
Delivery Date, the Lender will be entitled to revoke the relevant Notice of
Conversion by delivering a notice to such effect to the Company, whereupon the
Company and the Lender shall each be restored to their respective positions
immediately prior to delivery of such Notice of Conversion; provided, however,
that an amount equal to any payments contemplated by this Section 5(c) which
have accrued through the date of such revocation notice shall remain due and
owing to the Converting Holder notwithstanding such revocation.

          D.   If, by the relevant Delivery Date, the Company fails for any
reason to deliver the Shares to be issued upon conversion of a Debenture and
after such Delivery Date, the Holder of the Debentures being converted (a
"Converting Holder") purchases, in an arm's-length open market transaction or
otherwise, shares of Common Stock (the "Covering Shares") in order to make
delivery in satisfaction of a sale of Common Stock by the Converting Holder (the
"Sold Shares"), which delivery such Converting Holder anticipated to make using
the Shares to be issued upon such conversion (a "Buy-In"), the Converting Holder
shall have the right, to require the Company to pay to the Converting Holder, in
addition to and not in lieu of the amounts due under Section 5(c) hereof (but in
addition to all other amounts contemplated in other provisions of the
Transaction Agreements, and not in lieu of any such other amounts), the Buy-In
Adjustment Amount (as defined below). The "Buy-In Adjustment Amount" is the
amount equal to the excess, if any, of (x) the Converting Holder's total
purchase price (including brokerage commissions, if any) for the Covering Shares
over (y) the net proceeds (after brokerage commissions, if any) received by the
Converting Holder from the sale of the Sold Shares. The Company shall pay the
Buy-In Adjustment Amount to the Company in immediately available funds
immediately upon demand by the Converting Holder. By way of illustration and not
in limitation of the foregoing, if the Converting Holder purchases shares of
Common Stock having a total purchase price (including brokerage commissions) of
$11,000 to cover a Buy-In with respect to shares of Common Stock it sold for net
proceeds of $10,000, the Buy-In Adjustment Amount which Company will be required
to pay to the Converting Holder will be $1,000.

          E.   In lieu of delivering physical certificates representing the
Common Stock issuable upon conversion, provided the Transfer Agent is
participating in the Depository Trust Company ("DTC") Fast Automated Securities
Transfer program, upon request of the Holder and its compliance with the
provisions contained in this paragraph, so long as the certificates therefor do
not bear a legend and the Holder thereof is not obligated to return such
certificate for the placement of a legend thereon, the Company shall use its
best efforts to cause the Transfer Agent to electronically transmit the Common
Stock issuable upon conversion to the Holder by crediting the account of
Holder's Prime Broker with DTC through its Deposit Withdrawal Agent Commission
system.

          F.   The holder of any Debentures shall be entitled to exercise its
conversion privilege with respect to the Debentures notwithstanding the
commencement of any case under

<PAGE>

11 U.S.C. ss.101 ET SEQ. (the "Bankruptcy Code"). In the event the Company is a
debtor under the Bankruptcy Code, the Company hereby waives, to the fullest
extent permitted, any rights to relief it may have under 11 U.S.C. ss.362 in
respect of such holder's conversion privilege. The Company hereby waives, to the
fullest extent permitted, any rights to relief it may have under 11 U.S.C.
ss.362 in respect of the conversion of the Debentures. The Company agrees,
without cost or expense to such holder, to take or to consent to any and all
action necessary to effectuate relief under 11 U.S.C. ss.362.

          G.   The Company will authorize the Transfer Agent to give information
relating to the Company directly to the Lender or the Lender's representatives
upon the request of the Lender or any such representative, to the extent such
information relates to (i) the status of shares of Common Stock issued or
claimed to be issued to the Lender in connection with a Notice of Conversion or
a Notice of Exercise, or (ii) the number of outstanding shares of Common Stock
of all shareholders as of a current or other specified date. At the request of
the Lender, the Company will provide the Lender with a copy of the authorization
so given to the Transfer Agent.

          6.   CLOSING DATES.

          A.   The Initial Closing Date shall occur on the date which is the
first Trading Day after each of the conditions contemplated by Sections 7 and 8
hereof shall have either been satisfied or been waived by the party in whose
favor such conditions run.

          B.   (i)   Subject to the provisions of subparagraph (iv) of this
Section 6(b), the Additional Closing Date shall be the date specified in the
Additional Closing Date Notice (as defined below).

               (ii)  Subject to the other provisions of this Section 6(b), the
term "Additional Closing Date Notice" means a written notice given by the
Company to the Lender and to the Escrow Agent by fax transmission or hand
delivery no later than one (1) business day after the Company submits the
Effectiveness Request (as defined below; a copy of the Effectiveness Request
shall be attached to the Additional Closing Date Notice).

               (iii) It also shall be a condition to the giving of an Additional
Closing Date Notice that the representations and warranties of the Company
contained in Section 3 hereof shall be true and correct in all material respects
and there shall have been no Material Adverse Effect from the Initial Closing
Date through and including the date the Company gives the Additional Closing
Date Notice to the Lender (and the Company's issuance of the Additional Closing
Date Notice shall constitute the Company's making each such representation and
warranty as of such date).

               (iv)  The Company also shall give written notice (an
"Effectiveness Notice") to the Lender and the Escrow Agent both (x) by fax
transmission or hand delivery and (y) by telephone communication of the actual
Effective Date declared by the SEC no later than

<PAGE>

noon on the first business day after such Effective Date; provided, however,
that an Effectiveness Notice may be given only if the Effective Date is on or
before April 30, 2004. The fifth (5th) day after the actual Effective Date,
which may be later than the date requested in the Effectiveness Request, shall
be the Additional Closing Date.

               (v)    The Company shall execute the Certificates for the
Additional Debentures and the Additional Warrants and deliver them to the Escrow
Agent at least one Trading Day prior to the Additional Closing Date. The "Issue
Date" identified in such Additional Debentures and the Expiration Date
identified in such Additional Warrants shall be left blank and the Company will
authorize the Escrow Agent, upon their release to the Lender, to fill in (x) the
date of the Additional Closing Date as the Issue Date in such Additional
Debentures and (y) the Expiration Date (as contemplated by Annex IV hereto) in
the Additional Warrants.

               (vi)   The term "Effectiveness Request" means the Company's
written request to the SEC that the SEC declare the Registration Statement
effective on a specified date; provided, however, that the Effectiveness Request
shall be given only after the SEC has advised the Company informally, in writing
or otherwise that it will respond favorably to such request.

               (vii)  Except as provided in this Section 6(b), the closing for
the Additional Debentures and the Additional Warrants shall be conducted upon
the same terms and conditions as those applicable to the Initial Debentures and
Initial Warrants.

               (viii) The Company hereby covenants and agrees that the Company
will issue each of the Additional Closing Date Notice and the Effectiveness
Notice to the Lender and the Escrow Agent on a timely basis.

               (ix)   If the Effective Date does not occur by the close of
business (Eastern time) on April 30, 2004, the obligations of the Lenders to
purchase the Additional Debentures and the Additional Warrants and the
obligations of the Company to issue the Additional Debentures and the Additional
Warrants shall automatically terminate (an "Additional Closing Date
Termination"). Such Additional Closing Date Termination shall not affect the
obligations of the Company or the Lender under any of the other Transaction
Agreements, including, without limitation, the Registration Rights Agreement,
except that the Transaction Agreements shall be deemed to refer only to the
Initial Debentures and the Initial Warrants and the transactions relating
thereto.

          C.   (i)    Each closing of the purchase and issuance of Debentures
and Warrants shall occur on the relevant Closing Date at the offices of the
Escrow Agent and shall take place no later than 3:00 P.M., New York time, on
such day or such other time as is mutually agreed upon by the Company and the
Lender.

               (ii)   If the Registration Statement Filing Time (as defined
below) does not occur by the close of business on November 7, 2003, then at any
time after that date and

<PAGE>

prior to the date on which the Registration Statement Filing Time occurs, the
Lender may, by written notice to the Escrow Agent (a "Cancellation Notice") with
a copy to the Company, request the return by the Escrow Agent to the Lender of
the Initial Purchase Price. Upon the Escrow Agent's receipt of such Cancellation
Notice, if the Registration Statement Filing Time has not occurred prior to 9 AM
(Eastern Time) of the Trading Day following such receipt by the Escrow Agent,
the Lender shall have no further obligations under this Agreement, including,
without limitation, the obligation to pay any part of the Aggregate Purchase
Price, and the Escrow Agent shall return the Lender's Escrow Funds to the Lender
and the Certificates issued to the Lender being held as part of the Escrow
Property to the Company.

               (iii)  If the Escrow Agent receives a Cancellation Notice from a
Lender, but the Registration Statement Filing Time occurs prior to 9 AM (Eastern
Time) of Trading Day following the Escrow Agent's receipt of such Cancellation
Notice, the Cancellation Notice shall be deemed null and void ab initio.

               (iv)   If, as a result of effective Cancellation Notices received
from one or more Lenders (whether such Lenders constitute all Lenders or less
than all Lenders), the Total Purchase Price of all remaining Lenders is less
than $2,000,000 (the "Minimum Purchase Price"), then, unless the Company
provides the Escrow Agent with an Additional Financing Notice (as defined below)
within two (2) Trading Days after its receipt of such Cancellation Notices, this
Agreement shall be deemed canceled with respect to all Lenders as if each of
them had timely given a Cancellation Notice. If the Company timely provides the
Escrow Agent with an Additional Financing Notice, the Cancellation Notices shall
apply only to the Lenders who have timely issued such Cancellation Notices;
provided, however, that if the Escrow Agent subsequently receives additional
Cancellation Notices, the provisions of this subparagraph (iv) shall apply.

               (v)    The term "Additional Financing Notice" means a written
notice certified to by the President, Chief Executive Officer or Chief Financial
Officer of the Company and confirmed by counsel to the Company to the effect
that the Company has binding commitments for funding for the Company for one or
more Permitted New Transactions, where, when the funding from such Permitted New
Transactions, when aggregated with the Total Purchase Price of Lenders who have
not issued Cancellation Notices, each of the following conditions apply: (x) the
aggregate funds (before fees and expenses and satisfaction of the Series 03-1
Debenture) to be received by the Company is at least $2,000,000, (y) the
aggregate funds (before fees and expenses and satisfaction of the Series 03-1
Debenture) to be received by the Company no later than two (2) Trading Days
after the Registration Statement Filing Time is at least $1,000,000, and (z) the
aggregate funds (before fees and expenses) to be received by the Company no
later than five (5) days after the Effective Date is at least $1,000,000 (the
conditions referred to in this sentence, the "Additional Financing Conditions").
Each Lender who has not issued a Cancellation Notice shall be a third party
beneficiary of the Additional Financing Notice. The Additional Financing Notice
will also include an undertaking by the Company to advise the Escrow Agent
immediately if any of the statements made in the Additional Financing Statement
would be reduced based on any events occurring subsequent to the Company's

<PAGE>

issuance of the Additional Financing Notice. The Escrow Agent may rely on the
Additional Financing Notice until it is revised by the Company. If the Company
subsequently revises the then current Additional Financing Notice so that the
Additional Financing Conditions are no longer true, the provisions of
subparagraph (iv) shall apply.

               (vi)   If the Company issues an Additional Financing Notice, it
shall be a condition to the release of the Escrow Funds for the Initial Purchase
Price that the Company re-issue a new Additional Financing Notice as of the date
of the Registration Statement Filing Time.

          D.   (i)    Notwithstanding anything to the contrary contained herein,
the Escrow Agent will be authorized to release the Escrow Funds to the Company
and to others and to release the other Escrow Property on the relevant Closing
Date upon satisfaction of the conditions set forth in Sections 7 and 8 hereof
and as provided in the Joint Escrow Instructions.

               (ii)   In furtherance of the foregoing and not in limitation
thereof, the parties acknowledge that, in connection with the purchase and sale
of the Initial Debentures and Initial Warrants, the Escrow Properties will be
deposited in escrow with the Escrow Agent as provided in Section 1 hereof (in
all events no later than the Trading Day immediately prior to the Initial
Closing Date) and be held in escrow until the Company delivers written notice to
the Escrow Agent that the Registration Statement, prepared in the manner
contemplated by the Registration Rights Agreement, has been filed and that such
filing is available on EDGAR (the time that the Registration Statement is marked
as filed by the SEC, as reflected on EDGAR is referred to as "Registration
Statement Filing Time"). The "Issue Date" identified in such Initial Debentures
and the Expiration Date identified in such Initial Warrants shall be left blank
and the Company will authorize the Escrow Agent, upon their release to the
Lender, to fill in (x) the date of the Initial Closing Date (or the later date
of the Escrow Agent's receipt of cleared Initial Purchase Price funds in escrow)
as the Issue Date in the relevant Lender's Initial Debentures and (y) the
Expiration Date (as contemplated by Annex IV hereto) in the Initial Warrants.
Furthermore, if, as contemplated by Section 6(c), the Company has issued an
Additional Financing Notice, it shall be a condition to the release of the
Escrow Funds for the Initial Purchase Price that the Company issue a new
Additional Financing Notice as of the date of the Registration Statement Filing
Time.

               (iii)  Upon the occurrence of an Additional Closing Date
Termination, the Escrow Agent shall return the Escrow Property, if any, relating
to the Additional Closing Date to the party which deposited such Escrow Property
in escrow.

          7.   CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL.

          The Lender understands that the Company's obligation to sell the
relevant Securities to the Lender pursuant to this Agreement on the relevant
Closing Date is conditioned upon:

<PAGE>

          B.   Delivery by the Lender to the Escrow Agent of good funds as
payment in full of an amount equal to the relevant Purchase Price for the
relevant Securities in accordance with this Agreement;

          C.   The accuracy on such Closing Date of the representations and
warranties of the Lender contained in this Agreement, each as if made on such
date, and the performance by the Lender on or before such date of all covenants
and agreements of the Lender required to be performed on or before such date;
and

          D.   There shall not be in effect any law, rule or regulation
prohibiting or restricting the transactions contemplated hereby, or requiring
any consent or approval which shall not have been obtained.

          B.   Delivery by the Company to the Escrow Agent of the relevant
Certificates in accordance with this Agreement;

          C.   Delivery by the Company to the Escrow Agent copies of (i) a

Company, together with evidence of the filing of the UCC-3 termination
statements, as executed by or filed on the authorization of CECONY, releasing
such security interests, and (ii) a written instrument executed by Consolidated

of first refusal and any other similar rights granted to ConEd by the Company;

          D.   Delivery by the Company to the Escrow Agent of written
confirmation that there are no changes to the Disclosure Letter, a copy of which
shall be attached to such confirmation;

          E.   Delivery by the Company to the Escrow Agent of the executed
Company Principal's Agreements from each Company Principal and the related
Principals (as defined in each Company Principal's Agreement) of such Company
Principal;

<PAGE>

          F.    On such Closing Date, each of the Transaction Agreements
executed by the Company on or before such date shall be in full force and effect
and the Company shall not be in default thereunder;

          G.    The accuracy in all material respects on such Closing Date of
the representations and warranties of the Company contained in this Agreement,
each as if made on such date, and the performance by the Company on or before
such date of all covenants and agreements of the Company required to be
performed on or before such date;

          H     On such Closing Date, the Lender shall have received an opinion
of counsel for the Company, dated such Closing Date, in form, scope and
substance reasonably satisfactory to the Lender, substantially to the effect set
forth in ANNEX III attached hereto;

          I.    There shall not be in effect any law, rule or regulation

inadvisable to purchase the Securities;

          K.    With respect to the Additional Closing Date,

          (i)   an Additional Closing Date Notice and an Effectiveness Notice
shall have been duly and timely given as provided in the relevant provisions of
Section 6(b);

          (ii)  the Registration Statement to cover all Registrable Securities

Company shall issue an Officer's Certificate substantially in the form of ANNEX
VIII hereto with respect thereto; provided, however, that such Officer's
Certificate may update certain information, such as the number of shares of the
Company's stock outstanding, included in Section 3).

<PAGE>

          9.   JURY TRIAL WAIVER. The Company and the Lender hereby waive a
trial by jury in any action, proceeding or counterclaim brought by either of the
Parties hereto against the other in respect of any matter arising out or in

          10.  GOVERNING LAW: MISCELLANEOUS.

          A.   This Agreement shall be governed by and interpreted in accordance
with the laws of the State of Delaware for contracts to be wholly performed in
such state and without giving effect to the principles thereof regarding the
conflict of laws. Each of the parties consents to the exclusive jurisdiction of

or the state courts of the State of Delaware sitting in the City of Wilmington
in connection with any dispute arising under this Agreement or any of the other
