                2.3 Puts of Common Shares to the Investor.

                        2.3.1 Procedure to Exercise a Put. Subject to the
Individual Put Limit, the Maximum Offering Amount and the Cap Amount (if
applicable), and the other conditions and limitations set forth in this
Agreement, at any time beginning on the date on which the



                                       10
   11

Registration Statement is declared effective by the SEC (the "Effective Date"),
the Company may, in its sole and absolute discretion, elect to exercise one or
more Puts according to the following procedure:

                                (a) Delivery of Advance Put Notice. At least ten
(10) Business Days but not more than twenty (20) Business Days prior to any
intended Put Date (unless otherwise agreed in writing by the Investor), the
Company shall deliver advance written notice (the "Advance Put Notice," the form
of which is attached hereto as Exhibit E, the date of such Advance Put Notice
being the "Advance Put Notice Date") to Investor stating the Put Date for which
the Company shall, subject to the limitations and restrictions contained herein,
exercise a Put and stating the number of shares of Common Stock (subject to the
Individual Put Limit and the Maximum Put Dollar Amount) which the Company
intends to sell to the Investor during the Pricing Period (the "Intended Put
Share Amount").

        The Company may, at its option, also designate in an Advance Put Notice
(i) a maximum dollar amount of Common Stock, not to exceed $2,000,000, which it
shall sell to Investor during the Put (the "Company Designated Maximum Put
Dollar Amount") and/or (ii) a minimum purchase price per Put Share at which the
Investor may purchase Shares pursuant to such Put Notice (a "Company Designated
Minimum Put Share Price"). The Company Designated Minimum Put Share Price shall
be no less than X% (as defined in Section 2.3.1 (c)) of the Closing Bid Price of
the Company's common stock on the Advance Put Notice Date.

        Notwithstanding the above, if more than two (2) Calendar Months have
passed since the date of the previous Put Closing, the Company shall deliver the
Advance Put Notice at least twenty (20) Business Days prior to any intended Put
Date, unless waived in writing by the Investor. In order to effect delivery of
the Advance Put Notice, the Company shall (i) send the Advance Put Notice by
facsimile on such date so that such notice is received by the Investor by 6:00
p.m., New York, NY time, and (ii) surrender such notice on such date to a
courier for overnight delivery to the Investor (or two (2) day delivery in the
case of a Investor residing outside of the U.S.). Upon receipt by the Investor
of a facsimile copy of the Advance Put Notice, the Investor shall, within two
(2) Business Days, send, via facsimile, a confirmation of receipt (the "Advance
Put Notice Confirmation," the form of which is attached hereto as Exhibit F) of
the Advance Put Notice to the Company specifying that the Advance Put Notice has
been received and affirming the intended Put Date and the Intended Put Share
Amount.

                                (b) Put Share Amount. The "Put Share Amount" is
the number of shares of Common Stock that the Investor shall be obligated to
purchase in a given Put, and shall equal the lesser of (i) the Intended Put
Share Amount, and (ii) the Individual Put Limit. The "Individual Put Limit"
shall equal the lesser of (i) 20% of the sum of the daily reported trading
volume in the outstanding Common Stock on the Company's Principal Market during
each Evaluation Day (as defined below) of the Pricing Period, as extended or
shortened under the terms hereof, (ii) the number of Put Shares which, when
multiplied by their respective Put Share Prices, equals the Maximum Put Dollar
Amount, and (iii) 9.9% of the total amount of the Company's Common Stock that
would be outstanding upon completion of the Put.

                                (c) Put Share Price. The purchase price for the
Put Shares (the "Put Share Price") shall equal the lesser of (i) the Market
Price for such Put, minus $.05, or (ii)



                                       11
   12

X% (as defined below) of the Market Price for such Put, provided that the Put
Share Price shall in no event be less than the Company Designated Minimum Put
Share Price, where, for purposes hereof, "X" is defined as follows:





            Market Price for the Put                                   "X"
                                                                    
                  Below $1.00                                          80%
     $1.00 or greater, but less than $2.00                             85%
                $2.00 or greater                                       90%



                                (d) Delivery of Put Notice. After delivery of an
Advance Put Notice, on the Put Date specified in the Advance Put Notice, or on
the sixth (6th) Business Day following the last day of the previous Pricing
Period, whichever is later, the Company shall deliver written notice (the "Put
Notice," the form of which is attached hereto as Exhibit G) to Investor stating
(i) the Put Date, (ii) the Intended Put Share Amount as specified in the Advance
Put Notice (such exercise a "Put"), (iii) the Company Designated Maximum Put
Dollar Amount (if applicable), and (iv) the Company Designated Minimum Put Share
Price (if applicable). In order to effect delivery of the Put Notice, the
Company shall (i) send the Put Notice by facsimile on the Put Date so that such
notice is received by the Investor by 6:00 p.m., New York, NY time, and (ii)
surrender such notice on the Put Date to a courier for overnight delivery to the
Investor (or two (2) day delivery in the case of a Investor residing outside of
the U.S.). Upon receipt by the Investor of a facsimile copy of the Put Notice,
the Investor shall, within two (2) Business Days, send, via facsimile, a
confirmation of receipt (the "Put Notice Confirmation," the form of which is
attached hereto as Exhibit H) of the Put Notice to Company specifying that the
Put Notice has been received and affirming the Put Date and the Intended Put
Share Amount.

                                (e) Delivery of Required Put Documents. On or
before the Put Date for such Put, the Company shall deliver the Required Put
Documents (as defined in Section 2.3.5 below) to the Investor (or to an agent of
Investor, if Investor so directs). Unless otherwise specified by the Investor,
the Put Shares of Common Stock shall be transmitted electronically pursuant to
such electronic delivery system as the Investor shall request; otherwise
delivery shall be by physical certificates. If the Company has not delivered all
of the Required Put Documents to the Investor on or before the Put Date, the Put
shall be automatically cancelled, unless the Investor agrees to delay the Put
Date by up to three (3) Business Days, in which case the Pricing Period begins
on the Business Day following such new Put Date. If the Company has not
delivered all of the Required Put Documents to the Investor on or before the Put
Date (or new Put Date, if applicable), and the Investor has not agreed in
writing to delay the Put Date, the Put is automatically canceled (an
"Impermissible Put Cancellation") and, unless the Put was otherwise canceled in
accordance with the terms of Section 2.3.13, the Company shall pay the Investor
$5,000 for its reasonable due diligence expenses incurred in preparation for the
canceled Put and the Company may deliver an Advance Put Notice for the
subsequent Put no sooner than ten (10) Business Days after the date that such
Put was canceled.

delivered to the Investor, (i) whenever required by Section 2.3.6(b) or by
Section 2.6.3, and (ii) on the date that is three (3) Business Days prior to

independent counsel, in substantially the form of Exhibit R (the "Registration
Opinion"), addressed to the Investor stating, inter alia, that no facts
("Material Facts") have come to such counsel's attention that have caused it to
believe that the Registration Statement is subject to an Ineffective Period or
to believe that the Registration Statement, any Supplemental Registration
Statement (as each may be amended, if applicable), and any related prospectuses,
contains an untrue statement of material fact or omits a material fact required
to make the statements contained therein, in light of the circumstances under
which they were made, not misleading. If a Registration Opinion cannot be
delivered by the Company's independent counsel to the Investor on the
Registration Opinion Deadline due to the existence of Material Facts or an
Ineffective Period, the Company shall promptly notify the Investor and as
promptly as possible amend each of the Registration Statement and any
Supplemental Registration Statement, as applicable, and any related prospectus
or cause such Ineffective Period to terminate, as the case may be, and deliver
such Registration Opinion and updated prospectus as soon as possible



                                       15
   16

thereafter. If at any time after a Put Notice shall have been delivered to
Investor but before the related Pricing Period End Date, the Company acquires
knowledge of such Material Facts or any Ineffective Period occurs, the Company
shall promptly notify the Investor and shall deliver a Put Cancellation Notice
to the Investor pursuant to Section 2.3.13 by facsimile and overnight courier by
the end of that Business Day.

                                (b) (i) the Company shall engage its independent
auditors to perform the procedures in accordance with the provisions of
Statement on Auditing Standards No. 71, as amended, as agreed to by the parties
hereto, and reports thereon (the "Bring Down Cold Comfort Letters") as shall
have been reasonably requested by the Investor with respect to certain financial
information contained in the Registration Statement and shall have delivered to
the Investor such a report addressed to the Investor, on the date that is three
(3) Business Days prior to each Put Date.

                                    (ii) in the event that the Investor shall
have requested delivery of an "Agreed Upon Procedures Report" pursuant to
Section 2.6.3, the Company shall engage its independent auditors to perform
certain agreed upon procedures and report thereon as shall have been reasonably
requested by the Investor with respect to certain financial information of the
Company and the Company shall deliver to the Investor a copy of such report
addressed to the Investor. In the event that the report required by this Section
2.3.6(b) cannot be delivered by the Company's independent auditors, the Company
shall, if necessary, promptly revise the Registration Statement and the Company
shall not deliver a Put Notice until such report is delivered.


                        2.3.7 Mechanics of Purchase of Put Shares.

                                (a) Investor's Obligation and Right to Purchase
Shares. Subject to the conditions set forth in this Agreement, following the
Investor's receipt of a validly delivered Put Notice, the Investor shall be
required to purchase (each a "Purchase") from the Company a number of Put Shares
equal to the Put Share Amount, in the manner described below.

                                (b) Pricing Period. For purposes hereof, the
"Pricing Period," shall mean, unless otherwise shortened or lengthened under the
terms of this Agreement, the period beginning on the Business Day immediately
following the Put Date and ending on and including the date which is 20 Business
Days after such Put Date; provided that, if a Put Cancellation Notice has been
delivered to the Investor after the Put Date, the Pricing Period for such Put
shall end at the close of trading on the last full trading day on the Principal
Market that ends prior to the moment of initial delivery of the Put Cancellation
Notice (a "Truncated Pricing Period") to the Investor.

        The applicable Pricing Period shall be extended (a "Pricing Period
Extension") by one (1) Business Day for each Excluded Day during such Pricing
Period, up to a maximum extension of five (5) Business Days; provided that no
subsequent Put Notice may become effective until at least five (5) Business Days
after the end of the previous Pricing Period, as extended or shortened.



                                       16
   17

        For purposes of this Agreement:

                "Trigger Price" for any Pricing Period shall mean the greater of
(i) the Company Designated Minimum Put Share Price, plus $.05, or (ii) (100% /
X%) multiplied by the Company Designated Minimum Put Share Price, where "X" is
defined in Section 2.3.1(c) above.

                An "Evaluation Day" shall mean each Business Day during a
Pricing Period where the lowest intra-day trading price of the Common Stock is
greater than or equal to the Trigger Price.

                An "Excluded Day" shall mean each Business Day where the lowest
intra-day trading price of the Common Stock is less than the Trigger Price.


                        2.3.8 Mechanics of Put Closing. Each of the Company and
the Investor shall deliver all documents, instruments and writings required to
be delivered by either of them pursuant to this Agreement at or prior to each
Closing. Subject to such delivery and the satisfaction of the conditions set
forth in Sections 2.3.4 and 2.3.5, the closing of the purchase by the Investor
of Put Shares shall occur by 5:00 PM, New York City Time, on the date which is
five (5) Business Days following the applicable Pricing Period End Date (or such
other time or later date as is mutually agreed to by the Company and the
Investor) (the "Payment Due Date") at the offices of Investor. On each Closing
Date, the Investor shall deliver to the Company, in the manner specified in
Section 8 below, the Put Dollar Amount to be paid for such Put Shares,
determined as aforesaid. The closing (each a "Put Closing") for each Put shall
occur on the date that both (i) the Company has delivered to the Investor all
Required Put Documents, and (ii) the Investor has delivered to the Company such
Put Dollar Amount and any Late Payment Amount, if applicable (each a "Put
Closing Date").

        If the Investor does not deliver to the Company the Put Dollar Amount
for such Put on or before the Payment Due Date, then the Investor shall pay to
the Company, in addition to the Put Dollar Amount, an amount (the "Late Payment
Amount") at a rate of X% per month, accruing daily, multiplied by such Put
Dollar Amount, where "X" equals one percent (1%) for the first month following
the date in question, and increases by an additional one percent (1%) for each
month that passes after the date in question, up to a maximum of five percent
(5%).

                        2.3.9 [Intentionally Left Blank].

                        2.3.10 Limitation on Short Sales. The Investor and its
Affiliates shall not engage in short sales of the Company's Common Stock;
provided, however, that the Investor may enter into any short sale or other
hedging or similar arrangement it deems appropriate with respect to Put Shares
after it receives a Put Notice with respect to such Put Shares so long as such
sales or arrangements do not involve more than the number of such Put Shares
specified in the Put Notice.

                        2.3.11 Cap Amount. If the Company becomes listed on the
Nasdaq Small Cap Market or the Nasdaq National Market, then, unless the Company
has obtained Stockholder 20% Approval as set forth in Section 6.12 or unless
otherwise permitted by Nasdaq, in no event



                                       17
   18

shall the Aggregate Issued Shares exceed the maximum number of shares of Common
Stock (the "Cap Amount") that the Company can, without stockholder approval, so
issue pursuant to Nasdaq Rule 4460(i)(1)(d)(ii) (or any other applicable Nasdaq
Rules or any successor rule) (the "Nasdaq 20% Rule").

                        2.3.12 [Intentionally Left Blank]

                        2.3.13 Put Cancellation.

                                (a) Mechanics of Put Cancellation. If at any
time during a Pricing Period the Company discovers the existence of Material
Facts or any Ineffective Period or Delisting Event occurs, the Company shall
cancel the Put (a "Put Cancellation"), by delivering written notice to the
Investor (the "Put Cancellation Notice"), attached as Exhibit Q, by facsimile
and overnight courier. The "Put Cancellation Date" shall be the date that the
Put Cancellation Notice is first received by the Investor, if such notice is
received by the Investor by 6:00 p.m., New York, NY time, and shall be the
following date, if such notice is received by the Investor after 6:00 p.m., New
York, NY time.

                                (b) Effect of Put Cancellation. Anytime a Put
Cancellation Notice is delivered to Investor after the Put Date, the Put shall
remain effective with respect to a number of Put Shares (the "Truncated Put
Share Amount") which shall equal the lesser of (i) 20% of the sum of the daily
reported trading volume in the outstanding Common Stock on the Company's
Principal Market during each Evaluation Day of the Truncated Pricing Period,
(ii) the number of Put Shares which, when multiplied by their respective Put
Share Prices, equals the Maximum Put Dollar Amount, and (iii) 9.9% of the total
amount of the Company's Common Stock that would be outstanding upon completion
of the Put.

                                (c) Put Cancellation Notice Confirmation. Upon
receipt by the Investor of a facsimile copy of the Put Cancellation Notice, the
Investor shall promptly send, via facsimile, a confirmation of receipt (the "Put
Cancellation Notice Confirmation," a form of which is attached as Exhibit S) of
the Put Cancellation Notice to the Company specifying that the Put Cancellation
Notice has been received and affirming the Put Cancellation Date.

                        2.3.14 Investment Agreement Cancellation. The Company
may terminate (a "Company Termination") its right to initiate future Puts by
providing written notice ("Termination Notice") to the Investor, by facsimile
and overnight courier, at any time other than during an Extended Put Period,
provided that such termination shall have no effect on the parties' other rights
and obligations under this Agreement, the Registration Rights Agreement or the
Warrants. Notwithstanding the above, any cancellation occurring during an
Extended Put Period is governed by Section 2.3.13.

                        2.3.15 Return of Excess Common Shares. In the event that
the number of Shares purchased by the Investor pursuant to its obligations
hereunder is less than the Intended Put Share Amount, the Investor shall
promptly return to the Company any shares of Common Stock in the Investor's
possession that are not being purchased by the Investor.

                2.4 Warrants.

                      2.4.1  [Intentionally Omitted].

                        2.4.2 Purchase Warrants. Within five (5) Business Days
of the end of each Pricing Period, the Company shall issue and deliver to the
Investor a warrant ("Purchase Warrant"), in the form attached hereto as Exhibit
D, or such other form as agreed upon by the parties, to purchase a number of
shares of Common Stock equal to 15% of the number of Put Shares issued to
Investor in that Put. Each Purchase Warrant shall be exerciseable at a price
(the "Purchase Warrant Exercise Price") which shall initially equal 110% of the
Market Price on the Pricing Period End Date, and shall have annual reset
provisions. Each Purchase Warrant shall be immediately exercisable at the
Purchase Warrant Exercise Price, and shall have a term beginning on the date of
issuance and ending on date that is five (5) years thereafter. The Warrant
Shares shall be registered for resale pursuant to the Registration Rights
Agreement. Concurrently with the issuance and delivery of the Purchase Warrant
to the Investor, the Company shall deliver to the Investor a Purchase Warrant
Opinion of Counsel (signed by the Company's independent counsel).

                2.5 [Intentionally Left Blank].

                2.6 Due Diligence Review. The Company shall make available for
inspection and review by the Investor (the "Due Diligence Review"), advisors to
and representatives of the Investor (who may or may not be affiliated with the
Investor and who are reasonably acceptable to the Company), any underwriter
participating in any disposition of Common Stock on behalf of the Investor
pursuant to the Registration Statement, any Supplemental Registration Statement,
or amendments or supplements thereto or any blue sky, NASD or other filing, all
financial and other records, all SEC Documents and other filings with the SEC,
and all other corporate documents and properties of the Company as may be
reasonably necessary for the purpose of such review, and cause the Company's
officers, directors and employees to supply all such information reasonably
requested by the Investor or any such representative, advisor or underwriter in
connection with such Registration Statement (including, without limitation, in
response to all questions and other inquiries reasonably made or submitted by
any of them), prior to and from time to time after the filing and effectiveness
of the Registration Statement for the sole purpose of enabling the Investor and
such representatives, advisors and underwriters and their respective accountants
and attorneys to conduct initial and ongoing due diligence with respect to the
Company and the accuracy of the Registration Statement.

                        2.6.1 Treatment of Nonpublic Information. The Company
shall not disclose nonpublic information to the Investor or to its advisors or
representatives unless prior to disclosure of such information the Company
identifies such information as being nonpublic information and provides the
Investor and such advisors and representatives with the opportunity to accept or
refuse to accept such nonpublic information for review. The Company may, as a
condition to disclosing any nonpublic information hereunder, require the
Investor and its advisors and representatives to enter into a confidentiality
agreement (including an agreement with such advisors and representatives
prohibiting them from trading in Common Stock during such period of time as they
are in possession of nonpublic information) in form reasonably satisfactory to
the Company and the Investor.



                                       19
   20

        Nothing herein shall require the Company to disclose nonpublic
information to the Investor or its advisors or representatives, and the Company
represents that it does not disseminate nonpublic information to any investors
who purchase stock in the Company in a public offering, to money managers or to
securities analysts, provided, however, that notwithstanding anything herein to
the contrary, the Company will, as hereinabove provided, immediately notify the
advisors and representatives of the Investor and, if any, underwriters, of any
event or the existence of any circumstance (without any obligation to disclose
the specific event or circumstance) of which it becomes aware, constituting
nonpublic information (whether or not requested of the Company specifically or
generally during the course of due diligence by and such persons or entities),
which, if not disclosed in the Prospectus included in the Registration
Statement, would cause such Prospectus to include a material misstatement or to
omit a material fact required to be stated therein in order to make the
statements therein, in light of the circumstances in which they were made, not
misleading. Nothing contained in this Section 2.6 shall be construed to mean
that such persons or entities other than the Investor (without the written
consent of the Investor prior to disclosure of such information) may not obtain
nonpublic information in the course of conducting due diligence in accordance
with the terms of this Agreement; provided, however, that in no event shall the
Investor's advisors or representatives disclose to the Investor the nature of
the specific event or circumstances constituting any nonpublic information
discovered by such advisors or representatives in the course of their due
diligence without the written consent of the Investor prior to disclosure of
such information.

                        2.6.2 Disclosure of Misstatements and Omissions. The
Investor's advisors or representatives shall make complete disclosure to the
Investor's counsel of all events or circumstances constituting nonpublic
information discovered by such advisors or representatives in the course of
their due diligence upon which such advisors or representatives form the opinion
that the Registration Statement contains an untrue statement of a material fact
or omits a material fact required to be stated in the Registration Statement or
necessary to make the statements contained therein, in the light of the
circumstances in which they were made, not misleading. Upon receipt of such
disclosure, the Investor's counsel shall consult with the Company's independent
counsel in order to address the concern raised as to the existence of a material
misstatement or omission and to discuss appropriate disclosure with respect
thereto; provided, however, that such consultation shall not constitute the
advice of the Company's independent counsel to the Investor as to the accuracy
of the Registration Statement and related Prospectus.

                        2.6.3 Procedure if Material Facts are Reasonably
Believed to be Untrue or are Omitted. In the event after such consultation the
Investor or the Investor's counsel reasonably believes that the Registration
Statement contains an untrue statement or a material fact or omits a material
fact required to be stated in the Registration Statement or necessary to make
the statements contained therein, in light of the circumstances in which they
were made, not misleading,

                                (a) the Company shall file with the SEC an
amendment to the Registration Statement responsive to such alleged untrue
statement or omission and provide the Investor, as promptly as practicable, with
copies of the Registration Statement and related Prospectus, as so amended, or



                                       20
   21

                                (b) if the Company disputes the existence of any
such material misstatement or omission, (i) the Company's independent counsel
shall provide the Investor's counsel with a Registration Opinion and (ii) in the
event the dispute relates to the adequacy of financial disclosure and the
Investor shall reasonably request, the Company's independent auditors shall
provide to the Company a letter ("Agreed Upon Procedures Report") outlining the
performance of such "agreed upon procedures" as shall be reasonably requested by
the Investor and the Company shall provide the Investor with a copy of such
letter.

        2.7 Commitment Payments. On each six (6) month anniversary of the
Investment Commitment Closing, if the Investor has not received at least an
amount equal to the applicable Semi-Annual Commitment Fee, as set forth below,
in aggregate Gross Discount Amounts for the preceding six (6) Calendar Months
(each such period a "Commitment Evaluation Period"), the Company, in
consideration of Investor's commitment costs, including, but not limited to, due
diligence expenses, shall pay to the Investor an amount (the "Semi-Annual
Commitment Shortfall") equal to the difference of (i) the applicable Semi-Annual
Commitment Fee, as defined below, minus (ii) the aggregate of the Gross Discount
Amounts received by the Investor during the preceding six (6) Calendar Months.
In the event that the Company delivers a Termination Notice to the Investor, the
Company shall pay to the Investor the greater of (i) the Semi-Annual Commitment
Fee for the applicable Commitment Evaluation Period, less the Gross Discount
Amount on amounts put to the Investor in that Commitment Evaluation Period, or
(ii) the difference of (x) $200,000, minus (y) the aggregate of the Gross
Discount Amounts for all Puts to date, and the Company shall not be required to
pay the Semi-Annual Commitment Shortfall thereafter.

        For purposes hereof, the Semi-Annual Commitment Fee shall be as follows:



      Commitment Evaluation Period                          Semi-Annual Commitment Fee
      ----------------------------                          --------------------------
                                                         
First 6 Calendar Months after Closing*                               $50,000**
6 through 12 Calendar Months after Closing                           $75,000
12 through 18 Calendar Months after Closing                          $100,000
18 through 24 Calendar Months after Closing                          $100,000
24 through 30 Calendar Months after Closing                          $125,000
30 through 36 Calendar Months after Closing                          $150,000



* = Investment Commitment Closing

** = If the date of effectiveness of the Registration Statement is more than 4
Calendar Months after the date of filing of the Registration Statement, and the
Company has used its best efforts to cause such Registration Statement to become
effective as soon as possible, the Semi-Annual Commitment Fee for the First 6
Calendar Months After Closing shall be reduced to $25,000.

        The Company shall not be required to deliver any payments to Investor
under this subSection until Investor has paid all Put Dollar Amounts that are
then due.

within the meaning of Section 15 of the Act for any tax or legal advice (other

                        3.2.5 Investment Experience; Fend for Self. Investor has

securities other than those of the Company. Investor acknowledges that Investor
is able to fend for Investor's self in the transaction contemplated by this
Agreement, that Investor has the ability to bear the economic risk of Investor's
investment pursuant to this Agreement and that Investor is an "Accredited
Investor" by virtue of the fact that Investor meets the investor qualification
standards set forth in Section 3.1 above. Investor has not been organized for
the purpose of investing in securities of the Company, although such investment
is consistent with Investor's purposes.


                3.3 Exempt Offering Under Regulation D.

                        3.3.1 [Intentionally Left Blank].

                        3.3.2 No General Solicitation. The Investment Agreement
was not offered to Investor through, and Investor is not aware of, any form of
general solicitation or general advertising, including, without limitation, (i)
any advertisement, article, notice or other communication published in any
newspaper, magazine or similar media or broadcast over television or radio, and

solicitation or general advertising.

                        3.3.3 Restricted Securities. Investor understands that
the Investment Agreement is, the Common Stock and Warrants issued at each Put

securities" under the federal securities laws inasmuch as they are being
acquired from the Company in a transaction exempt from the registration
requirements of the federal securities laws and that under such laws and
applicable regulations such securities may not be transferred or resold without
registration under the Act or pursuant to an exemption therefrom. In this
connection, Investor represents that Investor is familiar with Rule 144 under
the Act, as presently in effect, and understands the resale limitations imposed
thereby and by the Act.

                        3.3.4 Disposition. Without in any way limiting the
representations set forth above, Investor agrees that until the Securities are
sold pursuant to an effective Registration Statement or an exemption from
registration, they will remain in the name of Investor and will not be
transferred to or assigned to any broker, dealer or depositary. Investor further
agrees not to sell, transfer, assign, or pledge the Securities (except for any
bona fide pledge arrangement to the extent that such pledge does not require
registration under the Act or unless an exemption from



                                       23
   24

such registration is available and provided further that if such pledge is
realized upon, any transfer to the pledgee shall comply with the requirements
set forth herein), or to otherwise dispose of all or any portion of the
Securities unless and until:

                                (a) There is then in effect a registration
statement under the Act and any applicable state securities laws covering such
proposed disposition and such disposition is made in accordance with such
registration statement and in compliance with applicable prospectus delivery
requirements; or

                                (b) (i) Investor shall have notified the Company
of the proposed disposition and shall have furnished the Company with a
statement of the circumstances surrounding the proposed disposition to the
extent relevant for determination of the availability of an exemption from
registration, and (ii) if reasonably requested by the Company, Investor shall
have furnished the Company with an opinion of counsel, reasonably satisfactory
to the Company, that such disposition will not require registration of the
Securities under the Act or state securities laws. It is agreed that the Company
will not require the Investor to provide opinions of counsel for transactions
made pursuant to Rule 144 provided that Investor and Investor's broker, if
necessary, provide the Company with the necessary representations for counsel to
the Company to issue an opinion with respect to such transaction.

                The Investor is entering into this Agreement for its own account
and the Investor has no present arrangement (whether or not legally binding) at
any time to sell the Common Stock to or through any person or entity; provided,
however, that by making the representations herein, the Investor does not agree
to hold the Common Stock for any minimum or other specific term and reserves the
right to dispose of the Common Stock at any time in accordance with federal and
state securities laws applicable to such disposition.


                3.4 Due Authorization.

representations, warranties, agreements and understandings set forth above are
true with respect to all partners of Investor (and if any such partner is itself
a partnership, all persons holding an interest in such partnership, directly or
indirectly, including through one or more partnerships), and the person



                                       24
   25

executing this Agreement has made due inquiry to determine the truthfulness of

        4. Acknowledgments Investor is aware that:

                4.1 Risks of Investment. Investor recognizes that an investment
in the Company involves substantial risks, including the potential loss of
Investor's entire investment herein. Investor recognizes that the Disclosure

the information, which would be contained in a registration statement under the
Act;

                4.2 No Government Approval. No federal or state agency has
passed upon the Securities, recommended or endorsed the Offering, or made any
finding or determination as to the fairness of this transaction;

this Agreement, the Securities and any component thereof have not been
registered under the Act or any applicable state securities laws by reason of
exemptions from the registration requirements of the Act and such laws, and may
not be sold, pledged (except for any limited pledge in connection with a margin
account of Investor to the extent that such pledge does not require registration
under the Act or unless an exemption from such registration is available and
provided further that if such pledge is realized upon, any transfer to the
pledgee shall comply with the requirements set forth herein), assigned or
otherwise disposed of in the absence of an effective registration of the
Securities and any component thereof under the Act or unless an exemption from
such registration is available;

                4.4 Restrictions on Transfer. Investor may not attempt to sell,
transfer, assign, pledge or otherwise dispose of all or any portion of the
Securities or any component thereof in the absence of either an effective
registration statement or an exemption from the registration requirements of the
Act and applicable state securities laws;

                4.5 No Assurances of Registration. There can be no assurance
that any registration statement will become effective at the scheduled time, or
ever, or remain effective when required, and Investor acknowledges that it may
be required to bear the economic risk of Investor's investment for an indefinite
period of time;

                4.6 Exempt Transaction. Investor understands that the Securities
are being offered and sold in reliance on specific exemptions from the
registration requirements of federal and state law and that the representations,
warranties, agreements, acknowledgments and understandings set forth herein are
being relied upon by the Company in determining the applicability of such
exemptions and the suitability of Investor to acquire such Securities.

               4.7 Legends. The certificates representing the Put Shares shall
not bear a Restrictive Legend. The certificates representing the Warrant Shares
shall not bear a Restrictive Legend unless they are issued at a time when the
Registration Statement is not effective for resale. It is understood that the
certificates evidencing any Warrant Shares issued at a time when the
Registration Statement is not effective for resale, subject to legend removal
under the terms of Section 6.9 below, shall bear the following legend (the
"Legend"):

        "The securities represented hereby have not been registered under the
        Securities Act of 1933, as amended, or applicable state securities laws,
        nor the securities laws of any other jurisdiction. They may not be sold
        or transferred in the absence of an effective registration statement
        under those securities laws or pursuant to an exemption therefrom."

        5. Representations and Warranties of the Company. The Company hereby
makes the following representations and warranties to Investor (which shall be
true at the signing of this Agreement, and as of any such later date as
contemplated hereunder) and agrees with Investor that, except as set forth in

laws of the State of Delaware, USA and has all requisite corporate power and
authority to carry on its business as now conducted and as proposed to be

standing in each jurisdiction in which the failure to so qualify would have a
material adverse effect on the business or properties of the Company and its
subsidiaries taken as a whole. The Company is not the subject of any pending,
threatened or, to its knowledge, contemplated investigation or administrative or
legal proceeding (a "Proceeding") by the Internal Revenue Service, the taxing
authorities of any state or local jurisdiction, or the Securities and Exchange
Commission, The National Association of Securities Dealer, Inc., The Nasdaq
Stock Market, Inc. or any state securities commission, or any other governmental

subsidiaries: Metacomp, Inc. (a California corporation) and Plasma Scientific
Corporation (a Delaware corporation).

               5.2 Corporate Condition. The Company's condition is, in all
material respects, as described in the Disclosure Documents (as further set
forth in any subsequently filed Disclosure Documents, if applicable), except for
changes in the ordinary course of business and normal year-end adjustments that
are not, in the aggregate, materially adverse to the Company. Except for
continuing losses, there have been no material adverse changes to the Company's
business, financial condition, or prospects since the dates of such Disclosure
Documents. The financial statements as contained in the 10-KSB and 10-QSB have
been prepared in accordance with generally accepted accounting principles,
consistently applied (except as otherwise permitted by Regulation S-X of the
Exchange Act), subject, in the case of unaudited interim financial statements,
to customary year end adjustments and the absence of certain footnotes, and
fairly present the financial condition of the Company as of the dates of the
balance sheets included therein and the consolidated results of its operations
and cash flows for the periods then ended,. Without limiting the foregoing,
there are no material liabilities, contingent or actual, that are not disclosed
in the Disclosure Documents (other than liabilities incurred by the Company in
the

                                       26
   27

ordinary course of its business, consistent with its past practice, after
the period covered by the Disclosure Documents). The Company has paid all
material taxes that are due, except for taxes that it reasonably disputes. There
is no material claim, litigation, or administrative proceeding pending or, to
the best of the Company's knowledge, threatened against the Company, except as
disclosed in the Disclosure Documents. This Agreement and the Disclosure
Documents do not contain any untrue statement of a material fact and do not omit
to state any material fact required to be stated therein or herein necessary to
make the statements contained therein or herein not misleading in the light of
the circumstances under which they were made. No event or circumstance exists
relating to the Company which, under applicable law, requires public disclosure
but which has not been so publicly announced or disclosed.

               5.3 Authorization. All corporate action on the part of the
Company by its officers, directors and stockholders necessary for the
authorization, execution and delivery of this Agreement, the performance of all
obligations of the Company hereunder and the authorization, issuance and
delivery of the Common Stock being sold hereunder and the issuance (and/or the
reservation for issuance) of the Warrants and the Warrant Shares have been
taken, and this Agreement and the Registration Rights Agreement constitute valid
and legally binding obligations of the Company, enforceable in accordance with
their terms, except insofar as the enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, or other similar laws affecting
creditors' rights generally or by principles governing the availability of
equitable remedies. The Company has obtained all consents and approvals required
for it to execute, deliver and perform each agreement referenced in the previous
sentence.

nonassessable and, based in part upon the representations of Investor in this
Agreement, will be issued in compliance with all applicable U.S. federal and
state securities laws. The Warrant Shares, when issued in accordance with the
terms of the Warrants, shall be duly and validly issued and outstanding, fully
paid and nonassessable, and based in part on the representations and warranties
of Investor, will be issued in compliance with all applicable U.S. federal and
state securities laws. The Put Shares, the Warrants and the Warrant Shares will
be issued free of any preemptive rights.

of any material provision of any material instrument or material contract to
which it is a party or by which it is bound or of any provision of any federal
or state judgment, writ, decree, order, statute, rule or governmental regulation
applicable to the Company, which would have a material adverse effect on the
Company's business or prospects, or on the performance of its obligations under
this Agreement or the Registration Rights Agreement. The execution, delivery and
performance of this Agreement and the other agreements entered into in
conjunction with the Offering and the consummation of the transactions
contemplated hereby and thereby will not (a) result in any such violation or be
in conflict with or constitute, with or without the passage of time and giving
of notice, either a default under any such provision, instrument or contract or
an event which results in the creation of any lien, charge or encumbrance upon
any assets of the Company, which would have a material adverse effect on the
Company's business or prospects, or on the performance of its obligations

                                       27
   28

under this Agreement, the Registration Rights Agreement, (b) violate the
Company's Certificate of Incorporation or By-Laws or (c) violate any statute,

requirements of the Exchange Act, has a class of securities registered under
Section 12 of the Exchange Act, and has filed all reports required by the
Exchange Act since the date the Company first became subject to such reporting
obligations. The Company undertakes to furnish Investor with copies of such

Offering and thereafter, to make such reports available, for the full term of
this Agreement, including any extensions thereof, and for as long as Investor
holds the Securities. The Common Stock is duly listed on the O.T.C. Bulletin

delisted by the O.T.C. Bulletin Board for the foreseeable future. The Company
has filed all reports required under the Exchange Act. The Company has not
furnished to the Investor any material nonpublic information concerning the
Company.

agreements or arrangements under which the Company or any of its subsidiaries is
obligated to register the sale of any of its or their securities under the Act
(except the Registration Rights Agreement).

and exclusive ownership of or rights to use the patents, trademarks, trademark
registrations, trade names, copyrights, know-how, technology and other
intellectual property necessary to the conduct of its business. Exhibit M lists
all patents, trademarks, trademark registrations, trade names and copyrights of
the Company. The Company has granted such licenses or has assigned or otherwise
transferred a portion of (or all of) such valid, unrestricted and exclusive
patents, trademarks, trademark registrations, trade names, copyrights, know-how,
technology and other intellectual property necessary to the conduct of its
business as set forth in Exhibit M. The Company has been granted licenses,
know-how, technology and/or other intellectual property necessary to the conduct

Investor may elect to hold the Securities for various periods of time, as
permitted by the terms of this Agreement, the Warrants, and other agreements
contemplated hereby, and the Company further acknowledges that Investor has made
no representations or warranties, either written or oral, as to how long the

is currently eligible and agrees to maintain its eligibility to register the
resale of its Common Stock on a registration statement on a suitable form under

affiliates, nor any person acting on its or their behalf, has directly or
indirectly made any offers or sales of any of the Company's securities or
solicited any offers to buy any security under circumstances that would prevent

pursuant to an exemption from registration under Regulation D of the Act or
would require the issuance of any other securities to be integrated with this
Offering under the Rules of Nasdaq. The Company has not engaged in any form of
general solicitation or advertising in connection with the offering of the
Common Stock or the Warrants.

               5.16  [Intentionally Left Blank].

actions for, or on behalf of, the Company, used any corporate funds for any
unlawful contribution, gift, entertainment or other unlawful expenses relating
to

                                       29
   30

Employee, to the best knowledge of the Company and its subsidiaries, is, or is
now expected to be, in violation of any material term of any employment
contract, confidentiality, disclosure or proprietary information agreement,
non-competition agreement, or any other contract or agreement or any restrictive
covenant, and the continued employment of each Key Employee does not subject the
Company or any of its subsidiaries to any liability with respect to any of the
foregoing matters. No Key Employee has, to the best knowledge of the Company and
its subsidiaries, any intention to terminate his employment with, or services
to, the Company or any of its subsidiaries.

               5.19 Representations Correct. The foregoing representations,
warranties and agreements are true, correct and complete in all material
respects, and shall survive any Put Closing and the issuance of the shares of
Common Stock thereby.

               5.20 Tax Status. The Company has made or filed all federal and
state income and all other tax returns, reports and declarations required by any
jurisdiction to which it is subject (unless and only to the extent that the
Company has set aside on its books provisions reasonably adequate for the
payment of all unpaid and unreported taxes) and has paid all taxes and other
governmental assessments and charges that are material in amount, shown or
determined to be due on such returns, reports and declarations, except those
being contested in good faith and as set aside on its books provision reasonably
adequate for the payment of all taxes for periods subsequent to the periods to
which such returns, reports or declarations apply. There are no unpaid taxes in
any material amount claimed to be due by the taxing authority of any
jurisdiction, and the officers of the Company know of no basis for any such
claim.

               5.21 Transactions With Affiliates. Except as set forth in the

by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any officer, director or such employee or, to the
knowledge of the Company, any corporation, partnership, trust or other entity in
which any officer, director, or any such employee has a substantial interest or
is an officer, director, trustee or partner.

               5.22 Application of Takeover Protections. The Company and its

inapplicable any control share acquisition, business combination or other
similar anti-takeover provision under Delaware law which is or could become

Agreement, including, without limitation, the issuance of the Common Stock, any
exercise of the Warrants and ownership of the Common Shares and Warrant Shares.

Agreement.

               5.23 Other Agreements. The Company has not, directly or
indirectly, made any agreements with the Investor under a subscription in the

Market or the Nasdaq National Market, or at a special meeting to be held as soon
as practicable thereafter, use its best efforts to obtain approval of its
shareholders to (i) authorize the issuance of the full number of shares of
Common Stock which would be issuable under this Agreement and eliminate any
prohibitions under applicable law or the rules or regulations of any stock
exchange, interdealer quotation system or other self-regulatory organization
with jurisdiction over the Company or any of its securities with respect to the
Company's ability to issue shares of Common Stock in excess of the Cap Amount
(such approvals being the "20% Approval") and (ii) the increase in the number of
authorized shares of Common Stock of the Company (the "Share Authorization
Increase Approval") such that at least 12,000,000 shares can be reserved for
this Offering. In connection with such shareholder vote, the Company shall use
its best efforts to cause all officers and directors of the Company to promptly
enter into irrevocable agreements to vote all of their shares in favor of
eliminating such prohibitions. As soon as practicable after the 20% Approval and
the Share Authorization Increase Approval, the Company agrees to use its best
efforts to reserve 12,000,000 shares of Common Stock for issuance under this
Agreement.

has Common Stock listed for trading on a stock exchange or on Nasdaq and is a
Reporting Issuer) and shall pay all its taxes when due except for taxes which

               6.6  Capital Raising Limitations; Rights of First Refusal.

                      6.6.1  Capital  Raising  Limitations.  During the period
from the date of this Agreement until the earlier of (i) the date that is one
year after the Termination Date, or (ii) (a) in the case of a Company
Termination, the date that is one (1) year after the date of such Company
Termination, or (b) in the case of an Automatic Termination that is not waived
by the Investor, the date that is six (6) months after the date of such
Automatic Termination, the Company shall not issue or sell, or agree to issue or
sell, for cash in private capital raising transactions (the following to be
collectively referred to herein as, the "Variable Priced Securities"), any debt
or equity securities which are convertible into, exercisable or exchangeable
for, or carry the right to receive additional shares of Common Stock either (i)
at any conversion, exercise or exchange rate or other price that is based upon
and/or varies with the trading prices of or quotations for Common Stock at any
time after the initial issuance of such debt or equity security, or (ii) with a
fixed conversion, exercise or exchange price that is subject to being reset at
some future date at any time after the initial issuance of such debt or equity
security or upon the occurrence of specified contingent events directly or

in private capital raising transactions any securities of the Company pursuant
to an equity line structure or format similar in nature to this Offering without
obtaining the prior written approval of the Investor of the Offering (the
limitations referred to in this sentence are collectively referred to as the
"Capital Raising Limitations"). Notwithstanding the above, during the period
from the date of this Agreement until the date that is two (2) weeks after the
date of this Agreement, this Section shall not prevent the Company from placing
up to $750,000 in purchase price of Common Stock, which may be accompanied by
warrants, and such warrants may contain a provision allowing for a reset of the

such warrants shall not increase as a result of such reset, and any such
placement that is completed prior to the date that is two (2) weeks after the
date of this Agreement shall not be included in the Investor's Right of First
Refusal set forth in Section 6.6.2 below.

                      6.6.2  Investor's Right of First Refusal.  For any
private capital raising transactions of Variable Priced Securities or equity
line structured investments which close after the Capital Raising Deadline and
on or prior to the date that is six (6) months after the

                                       32
   33

Termination Date of this Agreement, not including any warrants issued in
conjunction with this Investment Agreement, the Company agrees to deliver to
Investor, at least ten (10) days prior to the closing of such transaction,
written notice describing the proposed transaction, including the terms and
conditions thereof, and providing the Investor and its affiliates an option
during the ten (10) day period following delivery of such notice to purchase the
securities being offered in such transaction on the same terms as contemplated
by such transaction.

                      6.6.3  Exceptions to the Capital Raising Limitation and
Rights of First Refusal. Notwithstanding the above, the Capital Raising
Limitations and the Rights of First Refusal shall not apply to any transaction
involving issuances of securities in connection with a merger, consolidation,
acquisition or sale of assets, or in connection with any strategic partnership
or joint venture (the primary purpose of which is not to raise equity capital),
or in connection with the disposition or acquisition of a business, product or
license by the Company or exercise of options by employees, consultants or
directors. The Capital Raising Limitations also shall not apply to (a) the
issuance of securities upon exercise or conversion of the Company's options,
warrants or other convertible securities outstanding as of the date hereof, (b)
the grant of additional options or warrants, or the issuance of additional
securities, under any Company stock option or restricted stock plan for the
benefit of the Company's employees, directors or consultants, or (c) the
issuance of debt securities, with no equity feature, incurred solely for working
capital purposes.

               6.7 Financial 10-KSB Statements, Etc. and Current Reports on Form
8-K. The Company shall deliver to the Investor copies of its annual reports on
Form 10-KSB, and quarterly reports on Form 10-QSB and shall deliver to the
Investor current reports on Form 8-K within two (2) days of filing for the Term
of this Agreement.

               6.8 Opinion of Counsel. Investor shall, concurrent with the
purchase of the Common Stock and accompanying Warrants pursuant to this
Agreement, receive an opinion letter from the Company's legal counsel, in the
form attached as Exhibit B or in such form as agreed upon by the parties, as to
the Investment Commitment Closing and in the form attached as Exhibit I or in
such form as agreed upon by the parties, as to any Put Closing.

               6.9 Removal of Legend. If the certificates representing any
Securities are issued with a restrictive Legend in accordance with the terms of
this Agreement, the Legend shall be removed and the Company shall issue a
certificate without such Legend to the holder of any Security upon which it is
stamped, and a certificate for a security shall be originally issued without the
Legend, if (a) the sale of such Security is registered under the Act, or (b)
such holder provides the Company with an opinion of counsel, in form, substance
and scope customary for opinions of counsel in comparable transactions (the
reasonable cost of which shall be borne by the Investor), to the effect that a
public sale or transfer of such Security may be made without registration under
the Act, or (c) such holder provides the Company with reasonable assurances that
such Security can be sold pursuant to Rule 144. Each Investor agrees to sell all
Securities, including those represented by a certificate(s) from which the
Legend has been removed, or which were originally issued without the Legend,

connection with such sale or in compliance with an exemption from the
registration requirements of the Act.

               6.10 Listing. Subject to the remainder of this Section 6.10, the
Company shall ensure that its shares of Common Stock (including all Warrant
Shares) are listed and available for trading on the O.T.C. Bulletin Board.
Thereafter, the Company shall (i) use its best efforts to continue the listing
and trading of its Common Stock on the O.T.C. Bulletin Board or to become
eligible for and listed and available for trading on the Nasdaq Small Cap
Market, the NMS, or the New York Stock Exchange ("NYSE"); and (ii) comply in all
material respects with the Company's reporting, filing and other obligations
under the By-Laws or rules of the National Association of Securities Dealers
("NASD") and such exchanges, as applicable.

               6.11 The Company's Instructions to Transfer Agent. The Company
will instruct the Transfer Agent of the Common Stock, by delivering instructions
in the form of Exhibit T hereto, to issue certificates, registered in the name
of each Investor or its nominee, for the Put Shares and Warrant Shares in such
amounts as specified from time to time by the Company upon any exercise by the
Company of a Put and/or exercise of the Warrants by the holder thereof. Such
certificates shall not bear a Legend unless issuance with a Legend is permitted
by the terms of this Agreement and Legend removal is not permitted by Section
6.9 hereof and the Company shall cause the Transfer Agent to issue such
certificates without a Legend. Nothing in this Section shall affect in any way
Investor's obligations and agreement set forth in Sections 3.3.3 or 3.3.4 hereof
to resell the Securities pursuant to an effective registration statement and to
deliver a prospectus in connection with such sale or in compliance with an
exemption from the registration requirements of applicable securities laws. If
(a) a Investor provides the Company with an opinion of counsel, which opinion of
counsel shall be in form, substance and scope customary for opinions of counsel
in comparable transactions, to the effect that the Securities to be sold or
transferred may be sold or transferred pursuant to an exemption from
registration or (b) a Investor transfers Securities to an affiliate which is an
accredited investor pursuant to Rule 144, the Company shall permit the transfer,
and, in the case of Put Shares and Warrant Shares, promptly instruct its
transfer agent to issue one or more certificates in such name and in such
denomination as specified by such Investor. The Company acknowledges that a
breach by it of its obligations hereunder will cause irreparable harm to a
Investor by vitiating the intent and purpose of the transaction contemplated
hereby. Accordingly, the Company acknowledges that the remedy at law for a
breach of its obligations under this Section 6.11 will be inadequate and agrees,
in the event of a breach or threatened breach by the Company of the provisions
of this Section 6.11, that a Investor shall be entitled, in addition to all
other available remedies, to an injunction restraining any breach and requiring
immediate issuance and transfer, without the necessity of showing economic loss
and without any bond or other security being required.

               6.12 Stockholder 20% Approval. Prior to the closing of any Put
that would cause the Aggregate Issued Shares to exceed the Cap Amount, the
Company shall obtain approval of its stockholders to authorize (i) the issuance
of the full number of shares of Common Stock which would be issuable pursuant to
this Agreement but for the Cap Amount and eliminate any prohibitions under
applicable law or the rules or regulations of any stock exchange, interdealer
quotation system or other self-regulatory organization with jurisdiction over
the Company or any of its securities with respect to the Company's ability to
issue shares of Common Stock in excess of the Cap Amount (such approvals being
the "Stockholder 20% Approval").

   35

               6.13 Press Release. The Company agrees that the Investor shall
have the right to review and comment upon any press release issued by the
Company in connection with the Offering which approval shall not be unreasonably
withheld by Investor.

               6.14 Change in Law or Policy. In the event of a change in law, or
policy of the SEC, as evidenced by a No-Action letter or other written
statements of the SEC or the NASD which causes the Investor to be unable to
perform its obligations hereunder, this Agreement shall be automatically
terminated and no further Commitment Fees shall be due.


        7. Investor Covenant/Miscellaneous.

               7.1 Representations and Warranties Survive the Closing;
Severability. Investor's and the Company's representations and warranties shall
survive the Investment Date and any Put Closing contemplated by this Agreement
notwithstanding any due diligence investigation made by or on behalf of the
party seeking to rely thereon. In the event that any provision of this Agreement
becomes or is declared by a court of competent jurisdiction to be illegal,
unenforceable or void, or is altered by a term required by the Securities
Exchange Commission to be included in the Registration Statement, this Agreement
shall continue in full force and effect without said provision; provided that if
the removal of such provision materially changes the economic benefit of this
Agreement to the Investor, the Investor, at its option, may terminate this
Agreement or require that other terms of the Agreement be amended to compensate

               7.8 Arbitration. Except as otherwise provided in Section 6.11 of
this Agreement, any controversy or claim arising out of or related to the
Transaction Documents or the breach thereof, shall be settled by binding
arbitration in Wilmington, Delaware in accordance with the Expedited Procedures
(Rules 53-57) of the Commercial Arbitration Rules of the American Arbitration
Association ("AAA"). A proceeding shall be commenced upon written demand by
Company or any Investor to the other. The arbitrator(s) shall enter a judgment
by default against any party, which fails or refuses to appear in any properly
noticed arbitration proceeding. The proceeding shall be conducted by one (1)
arbitrator, unless the amount alleged to be in dispute exceeds two hundred fifty
thousand dollars ($250,000), in which case three (3) arbitrators shall preside.
The arbitrator(s) will be chosen by the parties from a list provided by the AAA,
and if they are unable to agree within ten (10) days, the AAA shall select the
arbitrator(s). The arbitrators must be experts in securities law and financial
transactions. The arbitrators shall assess costs and expenses of the
arbitration, including all attorneys' and experts' fees, as the arbitrators
believe is appropriate in light of the merits of the parties' respective
positions in the issues in dispute. Each party submits irrevocably to the
jurisdiction of any state court sitting in Wilmington, Delaware or to the United
States District Court sitting in Delaware for purposes of enforcement of any
discovery order, judgment or award in connection with such arbitration. The
award of the arbitrator(s) shall be final and binding upon the parties and may
be enforced in any court having jurisdiction. The arbitration shall be held in
such place as set by the arbitrator(s) in accordance with Rule 55.

               Although the parties, as expressed above, agree that all claims,
including claims that are equitable in nature, for example specific performance,
shall initially be prosecuted in the binding arbitration procedure outlined
above, if the arbitration panel dismisses or otherwise fails

                                       36
   37

to entertain any or all of the equitable claims asserted by reason of the fact
that it lacks jurisdiction, power and/or authority to consider such claims
and/or direct the remedy requested, then, in only that event, will the parties
have the right to initiate litigation respecting such equitable claims or
remedies. The forum for such equitable relief shall be in either a state or
federal court sitting in Wilmington, Delaware. Each party waives any right to a
trial by jury, assuming such right exists in an equitable proceeding, and
irrevocably submits to the jurisdiction of said Delaware court. Delaware law
shall govern both the proceeding as well as the interpretation and construction
of the Transaction Documents and the transaction as a whole.

        8.     Subscription and Wiring Instructions; Irrevocability.

               8.1  Subscription

               (a)  Wire transfer of Subscription Funds. Investor shall deliver
                    Put Dollar Amounts (as payment towards any Put Share Price)
                    by wire transfer, to the Company pursuant to a wire
                    instruction letter to be provided by the Company, and signed
                    by the Company.

               (b)  Irrevocable Subscription. Investor hereby acknowledges and
                    agrees, subject to the provisions of any applicable laws
                    providing for the refund of subscription amounts submitted
                    by Investor, that this Agreement is irrevocable and that
                    Investor is not entitled to cancel, terminate or revoke this
                    Agreement or any other agreements executed by such Investor
                    and delivered pursuant hereto, and that this Agreement and
                    such other agreements shall survive the death or disability
                    of such Investor and shall be binding upon and inure to the
                    benefit of the parties and their heirs, executors,
                    administrators, successors, legal representatives and
                    assigns. If the Securities subscribed for are to be owned by
                    more than one person, the obligations of all such owners
                    under this Agreement shall be joint and several, and the
                    agreements, representations, warranties and acknowledgments
                    herein contained shall be deemed to be made by and be
                    binding upon each such person and his heirs, executors,
                    administrators, successors, legal representatives and
                    assigns.

               8.2 Acceptance of Subscription. Ownership of the number of
securities purchased hereby will pass to Investor upon the Warrant Closing or
any Put Closing.

               8.3    [Intentionally Omitted]

        9.     Indemnification.

        In consideration of the Investor's execution and delivery of the
Investment Agreement, the Registration Rights Agreement and the Warrants (the
"Transaction Documents") and acquiring the Securities thereunder and in addition
to all of the Company's other obligations under the Transaction Documents, the
Company shall defend, protect, indemnify and hold harmless Investor and all of
its stockholders, officers, directors, employees and direct or indirect
investors and any of the foregoing person's agents, members, partners or other
representatives (including, without

                                       37
   38

limitation, those retained in connection with the transactions contemplated by
this Agreement) (collectively, the "Indemnitees") from and against any and all
actions, causes of action, suits, claims, losses, costs, penalties, fees,
liabilities and damages, and expenses in connection therewith (irrespective of
whether any such Indemnitee is a party to the action for which indemnification
hereunder is sought), and including reasonable attorney's fees and disbursements
(the "Indemnified Liabilities"), incurred by any Indemnitee as a result of, or
arising out of, or relating to (a) any misrepresentation or breach of any
representation or warranty made by the Company in the Transaction Documents or
any other certificate, instrument or documents contemplated hereby or thereby,
(b) any breach of any covenant, agreement or obligation of the Company contained
in the Transaction Documents or any other certificate, instrument or document
contemplated hereby or thereby, or (c) any cause of action, suit or claim,
derivative or otherwise, by any stockholder of the Company based on a breach or
alleged breach by the Company or any of its officers or directors of their
fiduciary or other obligations to the stockholders of the Company.

        To the extent that the foregoing undertaking by the Company may be
unenforceable for any reason, the Company shall make the maximum contribution to
the payment and satisfaction of each of the Indemnified Liabilities which it
would be required to make if such foregoing undertaking was enforceable which is
permissible under applicable law.

        Promptly after receipt by an Indemnified Party of notice of the
commencement of any action pursuant to which indemnification may be sought, such
Indemnified Party will, if a claim in respect thereof is to be made against the
other party (hereinafter "Indemnitor") under this Section 9, deliver to the
Indemnitor a written notice of the commencement thereof and the Indemnitor shall
have the right to participate in and to assume the defense thereof with counsel
reasonably selected by the Indemnitor, provided, however, that an Indemnified
Party shall have the right to retain its own counsel, with the reasonably
incurred fees and expenses of such counsel to be paid by the Indemnitor, if
representation of such Indemnified Party by the counsel retained by the
Indemnitor would be inappropriate due to actual or potential conflicts of
interest between such Indemnified Party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
Indemnitor within a reasonable time of the commencement of any such action, if
prejudicial to the Indemnitor's ability to defend such action, shall relieve the
Indemnitor of any liability to the Indemnified Party under this Section 9, but
the omission to so deliver written notice to the Indemnitor will not relieve it
of any liability that it may have to any Indemnified Party other than under this
Section 9 to the extent it is prejudicial.
