understands and agrees that the Securities have not been registered under the
1933 Act or any applicable state securities laws, by reason of their issuance in
a transaction that does not require registration under the 1933 Act (based in
part on the accuracy of the representations and warranties of Subscriber
contained herein), and that such Securities must be held indefinitely unless a
subsequent disposition is registered under the 1933 Act or any applicable state
securities laws or is exempt from such registration. Notwithstanding anything to

                                       7

of the Securities, except as may be required by any applicable federal or state
securities laws and unless contemporaneous notice of such instruction is given
to the Subscriber.

                           (m) DEFAULTS. Except as disclosed in this
Subscription Agreement, the Company is not in violation of its articles of
incorporation or bylaws. The Company is (i) not in default under or in violation
of any other material agreement or instrument to which it is a party or by which
it or any of its properties are bound or affected, which default or violation
would have a Material Adverse Effect, (ii) not subject to nor in default with
respect to any order of any court, arbitrator or governmental body or subject to
or party to any order of any court or governmental authority arising out of any
action, suit or proceeding under any statute or other law respecting antitrust,

the Company's knowledge not in violation of any statute, rule or regulation of
any governmental authority which violation would have a Material Adverse Effect.

                           (n) NOT AN INTEGRATED OFFERING. Neither the Company,
nor any of its Affiliates, nor any person acting on its or their behalf, has
knowingly, either directly or indirectly made any offers or sales of any
security or solicited any offers to buy any security under circumstances that
would cause the offer of the Securities pursuant to this Agreement to be
integrated with prior offerings by the Company for purposes of the 1933 Act or
any applicable stockholder approval provisions, including, without limitation,
under the rules and regulations of the OTC Bulletin Board ("BULLETIN BOARD")
which would impair the exemptions relied upon in this Offering [as defined in
Section 8(b)] or the Company's ability to timely comply with its obligations
hereunder. Nor will the Company or any of its Affiliates take any action or
steps that would knowingly cause the offer or issuance of the Securities to be
integrated with other offerings which would impair the exemptions relied upon in
this Offering or the Company's ability to timely comply with its obligations
hereunder. The Company will not knowingly conduct any offering other than the
transactions contemplated hereby that will be integrated with the offer or
issuance of the Securities, which would impair the exemptions relied upon in
this Offering or the Company's ability to timely comply with its obligations
hereunder.

                           (o) NO GENERAL SOLICITATION. Neither the Company, nor
any of its Affiliates, nor to its knowledge, any person acting on its or their
behalf, has engaged in any form of general solicitation or general advertising
(within the meaning of Regulation D under the 1933 Act) in connection with the
offer or sale of the Securities.

                           (p) LISTING. The Company's common stock is quoted on
the Bulletin Board under the symbol CEPO.OB. The Company has not received any
oral or written notice that the Common Stock is not eligible nor will become
ineligible for quotation on the Bulletin Board nor that the Common Stock does
not meet all requirements for the continuation of such quotation. The Company
satisfies all the requirements for the continued quotation of the Common Stock
on the Bulletin Board.

                           (q) NO UNDISCLOSED LIABILITIES. The Company has no
liabilities or obligations which are material, individually or in the aggregate,
which are not disclosed in the Reports and Other Written Information, other than
those incurred in the ordinary course of the Company's businesses since the
Latest Financial Date, and which, individually or in the aggregate, would
reasonably be expected to have a Material Adverse Effect.

                           (r) NO UNDISCLOSED EVENTS OR CIRCUMSTANCES. Since the
Latest Financial Date, no event or circumstance has occurred or exists with
respect to the Company or its businesses, properties, operations or financial
condition, that, under applicable law, rule or regulation, requires public
disclosure or announcement prior to the date hereof by the Company but which has
not been so publicly announced or disclosed in the Reports.

                           (s) CAPITALIZATION. The authorized and outstanding
capital stock of the Company as of the date immediately following the Closing
(not including the Securities) are set forth on SCHEDULE 5(D). Except as set

                                       8

forth on the SCHEDULE 5(D), there are no options, warrants, or rights to
subscribe to, securities, rights or obligations convertible into or exchangeable
for or giving any right to subscribe for any shares of capital stock of the
Company. All of the outstanding shares of Common Stock of the Company have been
duly and validly authorized and issued and are fully paid and nonassessable.

                           (t) DILUTION. The Company's executive officers and
directors understand the nature of the Securities being sold hereby and
recognize that the issuance of the Securities will have a potential dilutive
effect on the equity holdings of other holders of the Company's equity or rights
to receive equity of the Company. The board of directors of the Company has
concluded, in its good faith business judgment, that the issuance of the
Securities is in the best interests of the Company. The Company specifically
acknowledges that its obligation to issue the Shares upon conversion of the
Notes, 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 or parties entitled to
receive equity of the Company.

                           (u) NO DISAGREEMENTS WITH ACCOUNTANTS AND LAWYERS.
There are no disagreements of any kind presently existing, or reasonably
anticipated by the Company to arise, between the Company and the accountants and
lawyers formerly or presently employed by the Company, including but not limited
to disputes or conflicts over payment owed to such accountants and lawyers.

                           (v) DTC STATUS/TRANSFER AGENT. The Company's transfer
agent is eligible to participate in and the Common Stock is eligible for
transfer pursuant to the Depository Trust Company Automated Securities Transfer
Programs. The name, address, telephone number, fax number, contact person and

hereto.

                           (w) INVESTMENT COMPANY. Neither the Company nor any
Affiliate is an "investment company" within the meaning of the Investment
Company Act of 1940, as amended.

                           (x) CORRECTNESS OF REPRESENTATIONS. The Company
represents that the foregoing representations and warranties are true and
correct as of the date hereof in all material respects, and, unless the Company
otherwise notifies the Subscribers prior to the Closing Date, shall be true and
correct in all material respects as of the Closing Date.

                           (y) SURVIVAL. The foregoing representations and
warranties shall survive until three years after the Closing Date.

                  6. REGULATION D OFFERING. The offer and issuance of the
Securities to the Subscribers is being made pursuant to the exemption from the
registration provisions of the 1933 Act afforded by Section 4(2) or Section 4(6)
of the 1933 Act and/or Rule 506 of Regulation D promulgated thereunder. On the
Closing Date, the Company will provide an opinion reasonably acceptable to
Subscriber from the Company's legal counsel opining on the availability of an
exemption from registration under the 1933 Act as it relates to the offer and
issuance of the Securities and other matters reasonably requested by
Subscribers. A form of the legal opinion is annexed hereto as EXHIBIT D. The
Company will provide, at the Company's expense, such other legal opinions in the
future as are reasonably necessary for the issuance and resale of the Common
Stock issuable upon conversion of the Notes and exercise of the Warrants
pursuant to an effective registration statement, Rule 144 under the 1933 Act, or
an exemption from registration.

                  7.1. CONVERSION OF NOTE.

                           (a) Upon the conversion of a Note or part thereof,
the Company shall, at its own cost and expense, take all necessary action,
including obtaining and delivering, an opinion of counsel acceptable to the

                                       9

Company's transfer agent, so that the Company's transfer agent shall issue stock
certificates in the name of Subscriber (or its nominee) or such other persons as
designated by Subscriber and in such denominations to be specified at conversion
representing the number of shares of Common Stock issuable upon such conversion.
The Company warrants that no instructions other than these instructions have
been or will be given to the transfer agent of the Company's Common Stock and
that the certificates representing such shares shall contain no legend other
than the usual 1933 Act restriction from transfer legend. If and when the
Subscriber sells the Shares and Warrant Shares, assuming (i) the Registration
Statement (as defined below) is effective and the prospectus, as supplemented or
amended, contained therein is current and (ii) the Subscriber confirms in
writing to the transfer agent that the Subscriber has or will comply with the
prospectus delivery requirements, upon delivery to the purchaser, the
restrictive legend will be immediately removed and the Shares upon such sale
will be free-trading, and freely transferable. In the event that the Shares are
sold in a manner that complies with an exemption from registration, the Company
will promptly instruct its counsel to issue to the transfer agent an opinion
permitting removal of the legend (indefinitely, if pursuant to Rule 144(k) of
the 1933 Act, or for 90 days if pursuant to the other provisions of Rule 144 of
the 1933 Act).

                           (b) Subscriber will give notice of its decision to
exercise its right to convert the Note, interest, any sum due to the Subscriber
under the Transaction Documents including Liquidated Damages, or part thereof by
telecopying an executed and completed NOTICE OF CONVERSION (a form of which is
annexed as EXHIBIT A to the Note) to the Company via confirmed telecopier
transmission or otherwise pursuant to Section 13(a) of this Agreement. The
Subscriber will not be required to surrender the Note until the Note has been
fully converted or satisfied. Each date on which a Notice of Conversion is
telecopied to the Company in accordance with the provisions hereof shall be
deemed a CONVERSION DATE. The Company will itself or cause the Company's
transfer agent to transmit the Company's Common Stock certificates representing
the Shares issuable upon conversion of the Note to the Subscriber via express
courier for receipt by such Subscriber within three (3) business days after
receipt by the Company of the Notice of Conversion (such third day being the
"DELIVERY Date"). In the event the Shares are electronically transferable, then
delivery of the Shares MUST be made by electronic transfer provided request for
such electronic transfer has been made by the Subscriber and the Subscriber has
complied with all applicable securities laws in connection with the sale of the
Common Stock, including, without limitation, the prospectus delivery
requirements. A Note representing the balance of the Note not so converted will
be provided by the Company to the Subscriber if requested by Subscriber,
provided the Subscriber delivers the original Note to the Company. In the event
that a Subscriber elects not to surrender a Note for reissuance upon partial
payment or conversion, the Subscriber hereby indemnifies the Company against any
and all loss or damage attributable to a third-party claim in an amount in
excess of the actual amount then due under the Note. "BUSINESS DAY" and "TRADING
DAY" as employed in the Transaction Documents is a day that the New York Stock
Exchange is open for trading for three or more hours.

                           (c) The Company understands that a delay in the
delivery of the Shares in the form required pursuant to Section 7.1 hereof, or
the Mandatory Redemption Amount described in Section 7.2 hereof, respectively
after the Delivery Date or the Mandatory Redemption Payment Date (as hereinafter
defined) could result in economic loss to the Subscriber. As compensation to the
Subscriber for such loss, the Company agrees to pay (as liquidated damages and
not as a penalty) to the Subscriber for late issuance of Shares in the form
required pursuant to Section 7.1 hereof upon Conversion of the Note in the
amount of $100 per business day after the Delivery Date for each $10,000 of Note
principal amount being converted of the corresponding Shares which are not
timely delivered. The Company shall pay any payments incurred under this Section
in immediately available funds upon demand. Furthermore, in addition to any
other remedies which may be available to the Subscriber, in the event that the
Company fails for any reason to effect delivery of the Shares by the Delivery
Date or make payment by the Mandatory Redemption Payment Date, the Subscriber
may revoke all or part of the relevant Notice of Conversion or rescind all or
part of the notice of Mandatory Redemption by delivery of a notice to such
effect to the Company whereupon the Company and the Subscriber shall each be

                                       10

restored to their respective positions immediately prior to the delivery of such
notice, except that the liquidated damages described above shall be payable
through the date notice of revocation or rescission is given to the Company.

                           (d) Nothing contained herein or in any document
referred to herein or delivered in connection herewith shall be deemed to
establish or require the payment of a rate of interest or other charges in
excess of the maximum permitted by applicable law. In the event that the rate of
interest or dividends or damages required to be paid or other charges hereunder
exceed the maximum permitted by such law, any payments in excess of such maximum
shall be credited against amounts owed by the Company to the Subscriber and thus
refunded to the Company.

                  7.2. MANDATORY REDEMPTION AT SUBSCRIBER'S ELECTION. In the
event (i) the Company is prohibited from issuing Shares, (ii) the Company fails
to timely deliver Shares on a Delivery Date, (iii) upon the occurrence of any
other Event of Default (as defined in the Note or in this Agreement), any of the
foregoing that continues for more than twenty (20) business days, or (iv) of the
liquidation, dissolution or winding up of the Company, then at the Subscriber's
election, the Company must pay to the Subscriber ten (10) business days after
request by the Subscriber ("CALCULATION PERIOD"), a sum of money determined by
multiplying up to the outstanding principal amount of the Note designated by the
Subscriber by the greater of (y) 120%, or (z) a fraction in which the numerator
is the highest closing price of the Common Stock during the Calculation Period
and the denominator is the lowest applicable Conversion Price during the
Calculation Period, together with accrued but unpaid interest thereon
("MANDATORY REDEMPTION PAYMENT"). The Mandatory Redemption Payment must be
received by the Subscriber on the same date as the Shares otherwise deliverable
or within ten (10) business days after request, whichever is sooner ("MANDATORY
REDEMPTION PAYMENT DATE"). Upon receipt of the Mandatory Redemption Payment, the
corresponding Note principal and interest will be deemed paid and no longer
outstanding. Liquidated damages calculated pursuant to Section 7.1(c) hereof,
that have been paid or accrued for the ten day period prior to the actual
receipt of the Mandatory Redemption Payment by the Subscriber shall be credited
against the Mandatory Redemption Payment.

                  7.3. MAXIMUM CONVERSION. The Subscriber shall not be entitled
to convert on a Conversion Date that amount of the Note in connection with that
number of shares of Common Stock which would be in excess of the sum of (i) the
number of shares of common stock beneficially owned by the Subscriber and its
Affiliates on a Conversion Date, and (ii) the number of shares of Common Stock
issuable upon the conversion of the Note with respect to which the determination
of this provision is being made on a Conversion Date, which would result in
beneficial ownership by the Subscriber and its Affiliates of more than 4.99% of
the outstanding shares of common stock of the Company on such Conversion Date.
Beneficial ownership shall be determined in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended, and Regulation 13d-3 thereunder.
Subject to the foregoing, the Subscriber shall not be limited to aggregate
conversions of only 4.99% and aggregate conversions by the Subscriber may exceed
4.99%. The Subscriber may waive the conversion limitation described in this
Section 7.3, in whole or in part, upon and effective after 61 days prior written
notice to the Company to increase such percentage to up to 9.99%. The Subscriber
may decide whether to convert a Note or exercise Warrants to achieve an actual
4.99% or up to 9.99% ownership position as described above.

                  7.4. INJUNCTION POSTING OF BOND. In the event a Subscriber
shall elect to convert a Note or part thereof or exercise the Warrant in whole
or in part, the Company may not refuse conversion or exercise based on any claim
that such Subscriber or any one associated or affiliated with such Subscriber
has been engaged in any violation of law, or for any other reason, unless, an
injunction from a court, on notice, restraining and or enjoining conversion of
all or part of such Note or exercise of all or part of such Warrant shall have
been sought and obtained by the Company or at the Company's request or with the
Company's assistance, and the Company has posted a surety bond for the benefit
of such Subscriber in the amount of 120% of the outstanding principal and
interest of the Note, or aggregate purchase price of the Shares and Warrant
Shares which are sought to be subject to the injunction, which bond shall remain

                                       11

in effect until the completion of arbitration/litigation of the dispute and the
proceeds of which shall be payable to such Subscriber to the extent Subscriber
obtains judgment in Subscriber's favor.

                  7.5. BUY-IN. In addition to any other rights available to the
Subscriber, if the Company fails to deliver to the Subscriber such shares
issuable upon conversion of a Note by the Delivery Date and if after six (6)
business days after the Delivery Date the Subscriber or a broker on the
Subscriber's behalf, purchases (in an open market transaction or otherwise)
shares of Common Stock to deliver in satisfaction of a sale by such Subscriber
of the Common Stock which the Subscriber was entitled to receive upon such
conversion (a "BUY-IN"), then the Company shall pay in cash to the Subscriber
(in addition to any remedies available to or elected by the Subscriber) the
amount by which (A) the Subscriber's total purchase price (including brokerage
commissions, if any) for the shares of Common Stock so purchased exceeds (B) the
aggregate principal and/or interest amount of the Note for which such conversion
was not timely honored, together with interest thereon at a rate of 15% per
annum, accruing until such amount and any accrued interest thereon is paid in
full (which amount shall be paid as liquidated damages and not as a penalty).
For example, if the Subscriber purchases shares of Common Stock having a total
purchase price of $11,000 to cover a Buy-In with respect to an attempted
conversion of $10,000 of note principal and/or interest, the Company shall be
required to pay the Subscriber $1,000, plus interest. The Subscriber shall
provide the Company written notice indicating the amounts payable to the
Subscriber in respect of the Buy-In.

                  7.6 ADJUSTMENTS. The Conversion Price, Warrant exercise price
and amount of Shares issuable upon conversion of the Notes and exercise of the
Warrants shall be adjusted as described in this Agreement, the Notes and
Warrants.

                  7.7. REDEMPTION. The Securities shall not be redeemable or
mandatorily convertible except as described in the Note and Warrants.

                  8. BROKER/LEGAL FEES.

                           (a) BROKER'S COMMISSION. The Company on the one hand,
and each Subscriber (for himself only) on the other hand, agrees to indemnify
the other against and hold the other harmless from any and all liabilities to
any persons claiming brokerage commissions or similar fees other than the
persons and entities identified on SCHEDULE 8, (each a "BROKER") on account of
services purported to have been rendered on behalf of the indemnifying party in
connection with this Agreement or the transactions contemplated hereby and
arising out of such party's actions. Anything in this Agreement to the contrary
notwithstanding, each Subscriber is providing indemnification only for such
Subscriber's own actions and not for any action of any other Subscriber. The
Company agrees that it will pay the Broker the fee set forth on SCHEDULE 8
("BROKER'S FEES"). The Company represents that there are no other parties
entitled to receive fees, commissions, or similar payments in connection with
the offering described in this Agreement except the Broker and the party
identified on SCHEDULE 8 who will receive a yield enhancement fee, identified
thereon.

                           (b) LEGAL FEES. The Company shall pay to Grushko &
Mittman, P.C., a cash fee of $15,000 ("LEGAL FEES") as reimbursement for
services rendered to the Subscribers in connection with this Agreement and the
purchase and sale of the Notes and Warrants (the "OFFERING"). An additional cash
legal fee of $15,000 will be paid to Greenberg & Kahr on the Closing Date out of
funds held pursuant to the Escrow Agreement. The Legal Fees and reimbursement
for UCC search fees, if any, to be paid by the Company will be payable on the
Closing Date out of funds held pursuant to the Escrow Agreement.

                  9. COVENANTS OF THE COMPANY. The Company covenants and agrees
with the Subscribers as follows:

                                       12

                           (a) STOP ORDERS. The Company will advise the
Subscribers, within two hours after the Company receives notice of issuance by
the Commission, any state securities commission or any other regulatory
authority of any stop order or of any order preventing or suspending any
offering of any securities of the Company, or of the suspension of the
qualification of the Common Stock of the Company for offering or sale in any
jurisdiction, or the initiation of any proceeding for any such purpose.

                           (b) LISTING. If applicable, the Company shall
promptly secure the listing of the shares of Common Stock and the Warrant Shares
upon each national securities exchange, or electronic or automated quotation

such listing so long as any Notes or Warrants are outstanding. The Company will
maintain the listing or quotation of its Common Stock on the American Stock
Exchange, Nasdaq Capital Market, Nasdaq National Market System, Bulletin Board,

principal trading exchange or market for the Common Stock (the "PRINCIPAL
MARKET")), and will comply in all respects with the Company's reporting, filing
and other obligations under the bylaws or rules of the Principal Market, as
applicable. The Company will provide the Subscribers copies of all notices it
receives notifying the Company of the threatened and actual delisting of the
Common Stock from any Principal Market. As of the date of this Agreement, the
Bulletin Board is the Principal Market.

                           (c) MARKET REGULATIONS. If applicable, the Company
shall notify the Commission, the Principal Market and applicable state
authorities, in accordance with their requirements, of the transactions
contemplated by this Agreement, and shall take all other necessary action and
proceedings as may be required and permitted by applicable law, rule and
regulation, for the legal and valid issuance of the Securities to the
Subscribers and promptly provide copies thereof to Subscriber.

                           (d) FILING REQUIREMENTS. From the date of this
Agreement and until the sooner of (i) two (2) years after the Closing Date, or
(ii) until all the Shares and Warrant Shares have been resold or transferred by
all the Subscribers pursuant to the Registration Statement or pursuant to Rule

Stock to continue to be registered under Section 12(b) or 12(g) of the 1934 Act,
(B) comply in all respects with its reporting and filing obligations under the
1934 Act, (C) voluntarily comply with all reporting requirements that are
applicable to an issuer with a class of shares registered pursuant to Section
12(g) of the 1934 Act, if Company is not subject to such reporting requirements,

to terminate or suspend its reporting and filing obligations under said acts
until two (2) years after the Closing Date. Until the earlier of the resale of
the Shares and the Warrant Shares by each Subscriber or two (2) years after the
Closing Date, the Company will use its best efforts to continue the listing or

respects with the Company's reporting, filing and other obligations under the
bylaws or rules of the Principal Market. The Company agrees to timely file a
Form D with respect to the Securities if required under Regulation D and to
provide a copy thereof to each Subscriber promptly after such filing.

                           (e) USE OF PROCEEDS. The proceeds of the Offering
will be employed by the Company for the purposes set forth on SCHEDULE 9(E)
hereto. Except as set forth on SCHEDULE 9(E), the Purchase Price may not and

of the Company, litigation related expenses or settlements, brokerage fees, nor
non-trade obligations outstanding on a Closing Date.

                           (f) RESERVATION. Prior to the Closing Date, the
Company undertakes to reserve, PRO RATA, on behalf of the Subscribers from its
authorized but unissued common stock, a number of common shares equal to 110%
("CONVERSION SHARES RESERVATION MULTIPLE") of the amount of Common Stock
necessary to allow each Subscriber to be able to convert all Notes issuable

                                       13

pursuant to this Agreement and interest thereon. From and after August 21, 2006,
the Company will reserve 100% of the amount of Warrant Shares issuable upon
exercise of the Warrants, and the Conversion Shares Reservation Multiple shall
be 175%. Failure to have sufficient shares reserved pursuant to this Section
9(f) for thirty (30) days in the aggregate shall be a material default of the
Company's obligations under this Agreement and an Event of Default under the
Note.

                           (g) TAXES. From the date of this Agreement and until
the sooner of (i) two (2) years after the Closing Date, or (ii) until all the

to volume limitations, the Company will promptly pay and discharge, or cause to
be paid and discharged, when due and payable, all lawful taxes, assessments and
governmental charges or levies imposed upon the income, profits, property or
business of the Company; provided, however, that any such tax, assessment,
charge or levy need not be paid if the validity thereof shall currently be
contested in good faith by appropriate proceedings and if the Company shall have
set aside on its books adequate reserves with respect thereto, and provided,
further, that the Company will pay all such taxes, assessments, charges or
levies forthwith upon the commencement of proceedings to foreclose any lien
which may have attached as security therefore.

                           (h) INSURANCE. From the date of this Agreement and
until the sooner of (i) two (2) years after the Closing Date, or (ii) until all
the Shares and Warrant Shares have been resold or transferred by all the
Subscribers pursuant to the Registration Statement or pursuant to Rule 144,
without regard to volume limitations, the Company will keep its assets which are
of an insurable character insured by financially sound and reputable insurers
against loss or damage by fire, explosion and other risks customarily insured
against by companies in the Company's line of business, in amounts sufficient to
prevent the Company from becoming a co-insurer and not in any event less than
one hundred percent (100%) of the insurable value of the property insured less
reasonable deductible amounts; and the Company will maintain, with financially
sound and reputable insurers, insurance against other hazards and risks and
liability to persons and property to the extent and in the manner customary for
companies in similar businesses similarly situated and to the extent available
on commercially reasonable terms.

                           (i) BOOKS AND RECORDS. From the date of this
Agreement and until the sooner of (i) two (2) years after the Closing Date, or

144, without regard to volume limitations, the Company will keep true records
and books of account in which full, true and correct entries will be made of all
dealings or transactions in relation to its business and affairs in accordance
with generally accepted accounting principles applied on a consistent basis.

                           (j) GOVERNMENTAL AUTHORITIES. From the date of this
Agreement and until the sooner of (i) two (2) years after the Closing Date, or
(ii) until all the Shares and Warrant Shares have been resold or transferred by

144, without regard to volume limitations, the Company shall duly observe and
conform in all material respects to all valid requirements of governmental
authorities relating to the conduct of its business or to its properties or
assets.

                           (k) INTELLECTUAL PROPERTY. From the date of this
Agreement and until the sooner of (i) two (2) years after the Closing Date, or
(ii) until all the Shares and Warrant Shares have been resold or transferred by
all the Subscribers pursuant to the Registration Statement or pursuant to Rule
144, without regard to volume limitations, the Company shall maintain in full
force and effect its corporate existence, rights and franchises and all licenses
and other rights to use intellectual property owned or possessed by it and
reasonably deemed to be necessary to the conduct of its business, unless it is
sold for value.

                                       14

                           (l) PROPERTIES. From the date of this Agreement and
until the sooner of (i) two (2) years after the Closing Date, or (ii) until all
the Shares and Warrant Shares have been resold or transferred by all the
Subscribers pursuant to the Registration Statement (as defined in Section
11.1(ii) hereof) or pursuant to Rule 144, without regard to volume limitations,
the Company will keep its properties in good repair, working order and
condition, reasonable wear and tear excepted, and from time to time make all
necessary and proper repairs, renewals, replacements, additions and improvements
thereto; and the Company will at all times comply with each provision of all
leases to which it is a party or under which it occupies property if the breach
of such provision could reasonably be expected to have a Material Adverse
Effect.

                           (m) CONFIDENTIALITY/PUBLIC ANNOUNCEMENT. From the
date of this Agreement and until the sooner of (i) two (2) years after the
Closing Date, or (ii) until all the Shares and Warrant Shares have been resold
or transferred by all the Subscribers pursuant to the Registration Statement or
pursuant to Rule 144, without regard to volume limitations, the Company agrees
that except in connection with a Form 8-K or the Registration Statement or as
otherwise required in any other Commission filing, it will not disclose publicly
or privately the identity of the Subscribers unless expressly agreed to in
writing by a Subscriber, only to the extent required by law and then only upon
five days prior notice to Subscriber. In any event and subject to the foregoing,
the Company shall file a Form 8-K or make a public announcement describing the
Offering not later than the first business day after the Closing Date. In the
Form 8-K or public announcement, the Company will specifically disclose the
amount of common stock outstanding immediately after the Closing. A form of the
proposed Form 8-K or public announcement to be employed in connection with the
Closing is annexed hereto as EXHIBIT E.

                           (n) FURTHER REGISTRATION STATEMENTS. Except for a
registration statement filed on behalf of the Subscribers pursuant to Section 11
of this Agreement, and amendments necessary or desirable to maintain as current
the filed registration statements of the Company, or as set forth on SCHEDULE
11.1 hereto, the Company will not allow any other registration statement to be
declared effective nor file any registration statements, including but not
limited to Forms S-8, with the Commission or with state regulatory authorities
without the consent of the Subscriber until the expiration of the "EXCLUSION
PERIOD", which shall be defined as the sooner of (i) the Registration Statement
shall have been current and available for use in connection with the resale of
the Registrable Securities (as defined in Section 11.1(i) for a period of 60
days, or (ii) until all the Shares and Warrant Shares have been resold or
transferred by the Subscribers pursuant to the Registration Statement or Rule
144(k) under the 1933 Act, without regard to volume limitations. The Exclusion
Period will be tolled during the pendency of an Event of Default (as defined in
the Note).

                           (o) BLACKOUT. Other than such transaction that is
entered pursuant to which the Company actually repurchases the Notes in
accordance with their terms, the Company undertakes and covenants that until the
Registration Statement has been effective for one hundred and eighty days, the
Company will not enter into any acquisition, merger, exchange or sale or other
transaction that could have the effect of delaying the effectiveness of any
pending Registration Statement or causing an already effective Registration
Statement to no longer be effective or current.

                           (p) NON-PUBLIC INFORMATION. The Company covenants and
agrees that neither it nor any other person acting on its behalf will provide
any Subscriber or its agents or counsel with any information that the Company
believes constitutes material non-public information, unless prior thereto such
Subscriber shall have agreed in writing to receive such information. The Company
understands and confirms that each Subscriber shall be relying on the foregoing
representations in effecting transactions in securities of the Company. In any
event, the Company will offer to the Subscriber an opportunity to review and
comment on the Registration Statement thereto between three and five business
days prior to the proposed filing date thereof.

                                       15

                           (q) OFFERING RESTRICTIONS. Until the expiration of
the Exclusion Period and during the pendency of an Event of Default, except for
the Excepted Issuances, the Company will not enter into an agreement to, nor
issue any equity, convertible debt or other securities convertible into Common
Stock or equity of the Company nor modify any of the foregoing which may be
outstanding at anytime, without the prior written consent of the Subscriber,
which consent may be withheld for any reason. For so long as at least
twenty-five percent (25%) of the principal amount of the Notes is outstanding,
except for the Cornell "CETA" as described on SCHEDULE 12(A), the Company will
not enter into any equity line of credit or similar agreement, nor issue nor
agree to issue any floating or variable priced equity linked instruments nor any
of the foregoing or equity with price reset rights.

                           (r) NEGATIVE COVENANTS. So long as at least
twenty-five percent (25%) of the principal amount of the Notes issued on the
Closing Date is outstanding and during the pendency of an Event of Default (as
defined in the Note), without the consent of the Subscribers, other than the
Cornell Capital financing to be redeemed and as described in the Offering
materials or Schedules hereto or herein, the Company will not directly or
indirectly:

                                    (i) create, incur, assume or suffer to exist
any pledge, hypothecation, assignment, deposit arrangement, lien, charge, claim,
security interest, security title, mortgage, security deed or deed of trust,
easement or encumbrance, or preference, priority or other security agreement or
preferential arrangement of any kind or nature whatsoever (including any lease
or title retention agreement, any financing lease having substantially the same
economic effect as any of the foregoing, and the filing of, or agreement to
give, any financing statement perfecting a security interest under the Uniform
Commercial Code or comparable law of any jurisdiction) (each, a "LIEN") upon any
of its property, whether now owned or hereafter acquired except for (i) the
Excepted Issuances (as defined in Section 12(a) hereof), (ii) (a) Liens imposed
by law for taxes that are not yet due or are being contested in good faith and
for which adequate reserves have been established in accordance with generally
accepted accounting principles; (b) carriers', warehousemen's, mechanics',

ordinary course of business and securing obligations that are not overdue by
more than 30 days or that are being contested in good faith and by appropriate
proceedings; (c) pledges and deposits made in the ordinary course of business in
compliance with workers' compensation, unemployment insurance and other social
security laws or regulations; (d) deposits to secure the performance of bids,
trade contracts, leases, statutory obligations, surety and appeal bonds,
performance bonds and other obligations of a like nature, in each case in the
ordinary course of business; (e) Liens created with respect to the financing of
the purchase of new property in the ordinary course of the Company's business up
to the amount of the purchase price of such property, or (f) easements, zoning
restrictions, rights-of-way and similar encumbrances on real property imposed by
law or arising in the ordinary course of business that do not secure any
monetary obligations and do not materially detract from the value of the
affected property (each of (a) through (f), a "PERMITTED LIEN") and (iii)
indebtedness for borrowed money which is not senior or pari passu in right of
payment to the payment of the Notes;

                                    (ii) amend its certificate of incorporation,
bylaws or its charter documents so as to adversely affect any rights of the
Subscriber;

                                    (iii) repay, repurchase or offer to repay,
repurchase or otherwise acquire or make any dividend or distribution in respect
of any of its Common Stock, preferred stock, or other equity securities other
than to the extent permitted or required under the Transaction Documents;

                                    (iv) prepay any financing related debt

                                    (v) engage in any transactions with any
officer, director, employee or any Affiliate of the Company, including any
contract, agreement or other arrangement providing for the furnishing of
services to or 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 entity in which any officer,
director, or any such employee has a substantial interest or is an officer,

                                       16

director, trustee or partner, in each case in excess of $10,000 other than (i)
for payment of salary or consulting fees for services rendered, (ii)
reimbursement for expenses incurred on behalf of the Company, and (iii) for
other employee benefits, including stock option agreements under any stock
option plan of the Company, or interest previously owned by officers, directors,
or employees of the Company, as described on SCHEDULE 9(R).

                  10. COVENANTS OF THE COMPANY AND SUBSCRIBER REGARDING
INDEMNIFICATION.

                           (a) The Company agrees to indemnify, hold harmless,
reimburse and defend the Subscribers, the Subscribers' officers, directors,
agents, Affiliates, control persons, and principal shareholders, against any
claim, cost, expense, liability, obligation, loss or damage (including
reasonable legal fees) of any nature, incurred by or imposed upon the Subscriber
or any such person which results, arises out of or is based solely upon (i) any
material misrepresentation by Company or material breach of any warranty by
Company in this Agreement or in any Exhibits or Schedules attached hereto, or
other agreement delivered pursuant hereto; or (ii) after any applicable notice
and/or cure periods, any material breach or default in performance by the
Company of any covenant or undertaking to be performed by the Company hereunder,
or any other agreement entered into by the Company and Subscriber relating
hereto.

                           (b) Each Subscriber agrees to indemnify, hold
harmless, reimburse and defend the Company and each of the Company's officers,
directors, agents, Affiliates, control persons against any claim, cost, expense,
liability, obligation, loss or damage (including reasonable legal fees) of any
nature, incurred by or imposed upon the Company or any such person which
results, arises out of or is based solely upon (i) any material
misrepresentation by such Subscriber in this Agreement or in any Exhibits or
Schedules attached hereto, or other agreement delivered pursuant hereto; or (ii)
after any applicable notice and/or cure periods, any material breach or default
in performance by such Subscriber of any covenant or undertaking to be performed
by such Subscriber hereunder, or any other agreement entered into by the Company
and Subscribers, relating hereto.

                           (c) In no event shall the liability of any Subscriber
or permitted successor hereunder or under any Transaction Document or other
agreement delivered in connection herewith be greater in amount than the dollar
amount of the net proceeds actually received by such Subscriber upon the sale of
Registrable Securities (as defined herein).

                           (d) The procedures set forth in Section 11.6 shall
apply to the indemnification set forth in Sections 10(a) and 10(b) above.

                  11.1. REGISTRATION RIGHTS. The Company hereby grants the
following registration rights to holders of the Securities.

                           (i) On one occasion, for a period commencing one
hundred and fifty-one (151) days after the Closing Date, but not later than two
(2) years after the Closing Date, upon a written request therefor from any
record holder or holders of more than 50% of the Shares issued and issuable upon
conversion of the outstanding Notes and outstanding Warrant Shares, the Company
shall prepare and file with the Commission a registration statement under the
1933 Act registering the Registrable Securities, as defined in Section 11.1(iv)
hereof, which are the subject of such request for unrestricted public resale by
the holder thereof. For purposes of Sections 11.1(i) and 11.1(ii), Registrable
Securities shall not include Securities which are (A) registered for resale in
an effective registration statement, (B) included for registration in a pending
registration statement, or (C) which have been issued without further transfer
restrictions after a sale or transfer pursuant to Rule 144 under the 1933 Act.
Upon the receipt of such request, the Company shall promptly give written notice
to all other record holders of the Registrable Securities that such registration
statement is to be filed and shall include in such registration statement
Registrable Securities for which it has received written requests within ten
(10) days after the Company gives such written notice. Such other requesting

                                       17

record holders shall be deemed to have exercised their demand registration right
under this Section 11.1(i).

                           (ii) If the Company at any time proposes to register
any of its securities under the 1933 Act for sale to the public, whether for its
own account or for the account of other security holders or both, except with
respect to registration statements on Forms S-4, S-8 or another form not
available for registering the Registrable Securities for sale to the public,
provided the Registrable Securities are not otherwise registered for resale by
the Subscribers or Holder pursuant to an effective registration statement, each
such time it will give at least fifteen (15) days' prior written notice to the
record holder of the Registrable Securities of its intention so to do. Upon the
written request of the holder, received by the Company within ten (10) days
after the giving of any such notice by the Company, to register any of the
Registrable Securities not previously registered, the Company will cause such
Registrable Securities as to which registration shall have been so requested to
be included with the securities to be covered by the registration statement
proposed to be filed by the Company, all to the extent required to permit the
sale or other disposition of the Registrable Securities so registered by the
holder of such Registrable Securities (the "SELLER" or "SELLERS"). In the event
that any registration pursuant to this Section 11.1(ii) shall be, in whole or in
part, an underwritten public offering of common stock of the Company, the number
of shares of Registrable Securities to be included in such an underwriting may
be reduced by the managing underwriter if and to the extent that the Company and
the underwriter shall reasonably be of the opinion that such inclusion would
adversely affect the marketing of the securities to be sold by the Company
therein; provided, however, that the Company shall notify the Seller in writing
of any such reduction. Notwithstanding the foregoing provisions, or Section 11.4
hereof, the Company may withdraw or delay or suffer a delay of any registration
statement referred to in this Section 11.1(ii) without thereby incurring any
liability to the Seller.

                           (iii) If, at the time any written request for
registration is received by the Company pursuant to Section 11.1(i), the Company
has determined to proceed with the actual preparation and filing of a
registration statement under the 1933 Act in connection with the proposed offer
and sale for cash of any of its securities for the Company's own account and the
Company actually does file such other registration statement, such written
request shall be deemed to have been given pursuant to Section 11.1(ii) rather
than Section 11.1(i), and the rights of the holders of Registrable Securities
covered by such written request shall be governed by Section 11.1(ii).

                           (iv) In addition to the requirements set forth in
Section 11.1 and 11.2, the Company shall file with the Commission a Form SB-2
registration statement (the "REGISTRATION STATEMENT") (or such other form that
it is eligible to use) in order to register the Registrable Securities for
resale and distribution under the 1933 Act not later than August 21, 2006 (the
"FILING DATE"), and cause the Registration Statement to be declared effective
not later than one hundred and fifty (150) calendar days after the Closing Date
(the "EFFECTIVE DATE"). The Company will register not less than a number of
shares of common stock in the aforedescribed registration statement that is
equal to the amount of shares of Common Stock required at all times to be
reserved in the amounts described in Section 9(f) above (collectively the
"REGISTRABLE SECURITIES"). The Registrable Securities shall be reserved and set
aside exclusively for the benefit of each Subscriber and Warrant holder, PRO
RATA, and not issued, employed or reserved for anyone other than each such
Subscriber and Warrant holder. The Registration Statement will immediately be
amended or additional registration statements will be immediately filed by the
Company as necessary to register additional shares of Common Stock to allow the
public resale of all Common Stock included in and issuable by virtue of the
Registrable Securities. Except with the written consent of the Subscriber, no
securities of the Company other than the Registrable Securities will be included
in the Registration Statement. It shall be deemed a Non-Registration Event if at
any time after the date the Registration Statement is declared effective by the
Commission ("ACTUAL EFFECTIVE DATE") the Company has registered for unrestricted
resale on behalf of the Subscribers fewer than 125% of the amount of Common
Shares issuable upon full conversion of all sums due under the Notes and 100% of
the Warrant Shares issuable upon exercise of the Warrants.

                                       18

                  11.2. REGISTRATION PROCEDURES. If and whenever the Company is
required by the provisions of Section 11.1(i), 11.1(ii) or 11.1 (iv) to effect
the registration of any Registrable Securities under the 1933 Act, the Company
will, as expeditiously as possible:

                           (a) subject to the timelines provided in this
Agreement, prepare and file with the Commission a registration statement
required by Section 11, with respect to such securities and use its best efforts
to cause such registration statement to become and remain effective for the
period of the distribution contemplated thereby (determined as herein provided),
promptly provide to the holders of the Registrable Securities copies of all
filings and Commission letters of comment and notify Subscribers (by telecopier
and by e-mail to addresses provided by Subscribers, if any) and Grushko &
Mittman, P.C. (by telecopier and by email to COUNSLERS@AOL.COM) on or before the
first business day thereafter that the Company receives notice that (i) the
Commission has no comments or no further comments on the Registration Statement,
and (ii) the registration statement has been declared effective (failure to
timely provide notice as required by this Section 11.2(a) shall be a material
breach of the Company's obligation and an Event of Default as defined in the
Notes and a Non-Registration Event as defined in Section 11.4 of this
Agreement);

                           (b) prepare and file with the Commission such
amendments and supplements to such registration statement and the prospectus
used in connection therewith as may be necessary to keep such registration
statement effective until such registration statement has been effective for a
period of two (2) years, and comply with the provisions of the 1933 Act with
respect to the disposition of all of the Registrable Securities covered by such
registration statement in accordance with the Sellers' intended method of
disposition set forth in such registration statement for such period;

                           (c) furnish to the Sellers, at the Company's expense,
such number of copies of the registration statement and the prospectus included
therein (including each preliminary prospectus) as such persons reasonably may
request in order to facilitate the public sale or their disposition of the
securities covered by such registration statement or make them electronically
available;

                           (d) use its commercially reasonable best efforts to
register or qualify the Registrable Securities covered by such registration
statement under the securities or "blue sky" laws of New York and such
jurisdictions as the Sellers shall request in writing, provided, however, that
the Company shall not for any such purpose be required to qualify generally to
transact business as a foreign corporation in any jurisdiction where it is not
so qualified or to consent to general service of process in any such
jurisdiction;

                           (e) if applicable, list the Registrable Securities
covered by such registration statement with any securities exchange on which the
Common Stock of the Company is then listed;

                           (f) notify the Subscribers within four hours of the
Company's becoming aware that a prospectus relating thereto is required to be
delivered under the 1933 Act, of the happening of any event of which the Company
has knowledge as a result of which the prospectus contained in such registration
statement, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then
existing or which becomes subject to a Commission, state or other governmental
order suspending the effectiveness of the registration statement covering any of
the Registrable Securities;

                           (g) provided same would not be in violation of the
provision of Regulation FD under the 1934 Act, make available for inspection by
the Sellers, and any attorney, accountant or other agent retained by the Seller
or underwriter, all publicly available, non-confidential financial and other
records, pertinent corporate documents and properties of the Company, and cause
the Company's officers, directors and employees to supply all publicly

                                       19

available, non-confidential information reasonably requested by the seller,
attorney, accountant or agent in connection with such registration statement;
and

                           (h) provide to the Sellers copies of the Registration
Statement and amendments thereto five business days prior to the filing thereof
with the Commission.

                  11.3. PROVISION OF DOCUMENTS. In connection with each
registration described in this Section 11, each Seller will furnish to the
Company in writing such information and representation letters with respect to
itself and the proposed distribution by it as reasonably shall be necessary in
order to assure compliance with federal and applicable state securities laws.

                  11.4. NON-REGISTRATION EVENTS. The Company and the Subscribers
agree that the Sellers will suffer damages if the Registration Statement is not
filed by the Filing Date and not declared effective by the Commission by the
Effective Date, and any registration statement required under Section 11.1(i) or
11.1(ii) is not filed within 60 days after written request and declared
effective by the Commission within 120 days after such request, and maintained
in the manner and within the time periods contemplated by Section 11 hereof, and
it would not be feasible to ascertain the extent of such damages with precision.
Accordingly, if (A) the Registration Statement is not filed on or before the
Filing Date, (B) is not declared effective on or before the Effective Date, (C)
due to the action or inaction of the Company the Registration Statement is not
declared effective within three (3) business days after receipt by the Company
or its attorneys of a written or oral communication from the Commission that the
Registration Statement will not be reviewed or that the Commission has no
further comments, (D) if the registration statement described in Sections
11.1(i) or 11.1(ii) is not filed within 60 days after such written request, or
is not declared effective within 120 days after such written request, or (E) any
registration statement described in Sections 11.1(i), 11.1(ii) or 11.1(iv) is
filed and declared effective but shall thereafter cease to be effective without
being succeeded within fifteen (15) business days by an effective replacement or
amended registration statement or for a period of time which shall exceed thirty
(30) days in the aggregate per year (defined as every rolling period of 365
consecutive days commencing on the Actual Effective Date (each such event
referred to in clauses A through E of this Section 11.4 is referred to herein as
a "NON-REGISTRATION EVENT"), then the Company shall deliver to the holder of
Registrable Securities, as LIQUIDATED DAMAGES, an amount equal to two percent
(2%) for each thirty (30) days (or such lesser pro-rata amount for any period of
less than thirty (30) days) of the Purchase Price of the outstanding Notes and
purchase price of Shares issued upon conversion of the Notes owned of record by
such holder which are subject to such Non-Registration Event. The maximum
aggregate cash Liquidated Damages payable by the Company as a result of one or
more Non-Registration Events shall not exceed eighteen percent (18%) of the Note
principal issued in the Offering. The Company must pay the Liquidated Damages in
cash. The Liquidated Damages must be paid within ten (10) days after the end of
each thirty (30) day period or shorter part thereof for which Liquidated Damages
are payable. In the event a Registration Statement is filed by the Filing Date
but is withdrawn prior to being declared effective by the Commission, then such
Registration Statement will be deemed to have not been filed and Liquidated
Damages will be calculated accordingly. All oral or written comments received
from the Commission relating to the Registration Statement must be
satisfactorily responded to within ten (10) business days after receipt of
comments from the Commission. Failure to timely respond to Commission comments
is a Non-Registration Event for which Liquidated Damages shall accrue and be
payable by the Company to the holders of Registrable Securities at the same rate
set forth above. Notwithstanding the foregoing, the Company shall not be liable
to the Subscriber under this Section 11.4 for any events or delays occurring as
a consequence of the acts or omissions of the Subscribers contrary to the
obligations undertaken by Subscribers in this Agreement. Liquidated Damages will
not accrue nor be payable pursuant to this Section 11.4 nor will a
Non-Registration Event be deemed to have occurred for times during which
Registrable Securities are transferable by the holder of Registrable Securities
pursuant to Rule 144(k) under the 1933 Act.

                  11.5. EXPENSES. All expenses incurred by the Company in
complying with Section 11, including, without limitation, all registration and
filing fees, printing expenses (if required), fees and disbursements of counsel

                                       20

and independent public accountants for the Company, fees and expenses (including
reasonable counsel fees) incurred in connection with complying with state
securities or "blue sky" laws, fees of the National Association of Securities
Dealers, Inc., transfer taxes, and fees of transfer agents and registrars, are
called "REGISTRATION EXPENSES." All underwriting discounts and selling
commissions applicable to the sale of Registrable Securities are called "SELLING
EXPENSES." The Company will pay all Registration Expenses in connection with the
registration statement under Section 11. Selling Expenses in connection with
each registration statement under Section 11 shall be borne by the Seller and
may be apportioned among the Sellers in proportion to the number of shares sold
by the Seller relative to the number of shares sold under such registration
statement or as all Sellers thereunder may agree.

                  11.6. INDEMNIFICATION AND CONTRIBUTION.

                           (a) In the event of a registration of any Registrable
Securities under the 1933 Act pursuant to Section 11, the Company will, to the
extent permitted by law, indemnify and hold harmless the Seller, each officer of
the Seller, each director of the Seller, each underwriter of such Registrable
Securities thereunder and each other person, if any, who controls such Seller or
underwriter within the meaning of the 1933 Act, against any losses, claims,
damages or liabilities, joint or several, to which the Seller, or such
underwriter or controlling person may become subject under the 1933 Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
under which such Registrable Securities was registered under the 1933 Act
pursuant to Section 11, any preliminary prospectus or final prospectus contained
therein, or any amendment or supplement thereof, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading
in light of the circumstances when made, and will subject to the provisions of
Section 11.6(c) reimburse the Seller, each such underwriter and each such
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company shall not be liable to
the Seller to the extent that any such damages arise out of or are based upon an
untrue statement or omission made in any preliminary prospectus if (i) the
Seller failed to send or deliver a copy of the final prospectus delivered by the
Company to the Seller with or prior to the delivery of written confirmation of
the sale by the Seller to the person asserting the claim from which such damages
arise, (ii) the final prospectus would have corrected such untrue statement or
alleged untrue statement or such omission or alleged omission, or (iii) to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission so made in conformity with information furnished by any such Seller, or
any such controlling person in writing specifically for use in such registration
statement or prospectus.

                           (b) In the event of a registration of any of the
Registrable Securities under the 1933 Act pursuant to Section 11, each Seller
severally but not jointly will, to the extent permitted by law, indemnify and
hold harmless the Company, and each person, if any, who controls the Company
within the meaning of the 1933 Act, each officer of the Company who signs the
registration statement, each director of the Company, each underwriter and each
person who controls any underwriter within the meaning of the 1933 Act, against
all losses, claims, damages or liabilities, joint or several, to which the
Company or such officer, director, underwriter or controlling person may become
subject under the 1933 Act or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of any material fact contained
in the registration statement under which such Registrable Securities were
registered under the 1933 Act pursuant to Section 11, any preliminary prospectus
or final prospectus contained therein, or any amendment or supplement thereof,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse the Company and each such
officer, director, underwriter and controlling person for any legal or other
expenses reasonably incurred by them in connection with investigating or

                                       21

defending any such loss, claim, damage, liability or action, provided, however,
that the Seller will be liable hereunder in any such case if and only to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission made in reliance upon and in conformity with information pertaining to
such Seller, as such, furnished in writing to the Company by such Seller
specifically for use in such registration statement or prospectus, and provided,
further, however, that the liability of the Seller hereunder shall be limited to
the net proceeds actually received by the Seller from the sale of Registrable
Securities covered by such registration statement.

                           (c) Promptly after receipt by an indemnified party
hereunder of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party hereunder, notify the indemnifying party in writing thereof, but the
omission so to notify the indemnifying party shall not relieve it from any
liability which it may have to such indemnified party other than under this
Section 11.6(c) and shall only relieve it from any liability which it may have
to such indemnified party under this Section 11.6(c), except and only if and to
the extent the indemnifying party is prejudiced by such omission. In case any
such action shall be brought against any indemnified party and it shall notify
the indemnifying party of the commencement thereof, the indemnifying party shall
be entitled to participate in and, to the extent it shall wish, to assume and
undertake the defense thereof with counsel satisfactory to such indemnified
party, and, after notice from the indemnifying party to such indemnified party
of its election so to assume and undertake the defense thereof, the indemnifying
party shall not be liable to such indemnified party under this Section 11.6(c)
for any legal expenses subsequently incurred by such indemnified party in
connection with the defense thereof other than reasonable costs of investigation
and of liaison with counsel so selected, provided, however, that, if the
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be reasonable defenses available to it which are different from
or additional to those available to the indemnifying party or if the interests
of the indemnified party reasonably may be deemed to conflict with the interests
of the indemnifying party, the indemnified parties, as a group, shall have the
right to select one separate counsel and to assume such legal defenses and
otherwise to participate in the defense of such action, with the reasonable
expenses and fees of such separate counsel and other expenses related to such
participation to be reimbursed by the indemnifying party as incurred.

                           (d) In order to provide for just and equitable
contribution in the event of joint liability under the 1933 Act in any case in
which either (i) a Seller, or any controlling person of a Seller, makes a claim
for indemnification pursuant to this Section 11.6 but it is judicially
determined (by the entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last
right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 11.6 provides for indemnification in
such case, or (ii) contribution under the 1933 Act may be required on the part
of the Seller or controlling person of the Seller in circumstances for which
indemnification is not provided under this Section 11.6; then, and in each such
case, the Company and the Seller will contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (after contribution
from others) in such proportion so that the Seller is responsible only for the
portion represented by the percentage that the public offering price of its
securities offered by the registration statement bears to the public offering
price of all securities offered by such registration statement, provided,
however, that, in any such case, (y) the Seller will not be required to
contribute any amount in excess of the public offering price of all such
securities sold by it pursuant to such registration statement; and (z) no person
or entity guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) will be entitled to contribution from any person or
entity who was not guilty of such fraudulent misrepresentation.

                  11.7. DELIVERY OF UNLEGENDED SHARES.

                           (a) Within four (4) business days (such fourth
business day being the "UNLEGENDED SHARES DELIVERY DATE") after the business day
on which the Company has received (i) a notice that Shares or Warrant Shares or
any other Common Stock held by a Subscriber have been sold pursuant to the

                                       22

Registration Statement or Rule 144 under the 1933 Act, (ii) a representation
that the prospectus delivery requirements, or the requirements of Rule 144, as
applicable and if required, have been satisfied, and (iii) the original share
certificates representing the shares of Common Stock that have been sold, and
(iv) in the case of sales under Rule 144, customary representation letters of
the Subscriber and/or Subscriber's broker regarding compliance with the
requirements of Rule 144, the Company at its expense, (y) shall deliver, and
shall cause legal counsel selected by the Company to deliver to its transfer
agent (with copies to Subscriber) an appropriate instruction and opinion of such
counsel, directing the delivery of shares of Common Stock without any legends
including the legend set forth in Section 4(i) above, reissuable pursuant to any
effective and current Registration Statement described in Section 11 of this
Agreement or pursuant to Rule 144 under the 1933 Act (the "UNLEGENDED SHARES");
and (z) cause the transmission of the certificates representing the Unlegended
Shares together with a legended certificate representing the balance of the
submitted Shares certificate, if any, to the Subscriber at the address specified
in the notice of sale, via express courier, by electronic transfer or otherwise
on or before the Unlegended Shares Delivery Date.

                           (b) In lieu of delivering physical certificates
representing the Unlegended Shares, if the Company's transfer agent is
participating in the Depository Trust Company ("DTC") Fast Automated Securities
Transfer program, upon request of a Subscriber, so long as the certificates
therefor do not bear a legend and the Subscriber is not obligated to return such
certificate for the placement of a legend thereon, the Company shall cause its
transfer agent to electronically transmit the Unlegended Shares by crediting the
account of Subscriber's prime Broker with DTC through its Deposit Withdrawal
Agent Commission system. Such delivery must be made on or before the Unlegended
Shares Delivery Date.

                           (c) The Company understands that a delay in the
delivery of the Unlegended Shares pursuant to Section 11 hereof later than two
business days after the Unlegended Shares Delivery Date could result in economic
loss to a Subscriber. As compensation to a Subscriber for such loss, the Company
agrees to pay late payment fees (as liquidated damages and not as a penalty) to
the Subscriber for late delivery of Unlegended Shares in the amount of $100 per
business day after the Delivery Date for each $10,000 of purchase price of the
Unlegended Shares subject to the delivery default. If during any 360 day period,
the Company fails to deliver Unlegended Shares as required by this Section 11.7
for an aggregate of thirty (30) days, then each Subscriber or assignee holding
Securities subject to such default may, at its option, require the Company to
redeem all or any portion of the Shares and Warrant Shares subject to such
default at a price per share equal to the greater of (i) 120%, or (ii) a
fraction in which the numerator is the highest closing price during the
aforedescribed thirty day period and the denominator of which is the lowest
conversion price during such thirty day period, multiplied by the Purchase Price
of such Common Stock and Warrant Shares ("UNLEGENDED REDEMPTION AMOUNT"). The
amount of the aforedescribed liquidated damages that have accrued or been paid
for the ten day period prior to the receipt by the Subscriber of the Unlegended
Redemption Amount shall be credited against the Unlegended Redemption Amount.
The Company shall pay any payments incurred under this Section in immediately
available funds upon demand.

                           (d) In addition to any other rights available to a
Subscriber, if the Company fails to deliver to a Subscriber Unlegended Shares as
required pursuant to this Agreement, within six (6) business days after the
Unlegended Shares Delivery Date and the Subscriber or a broker on the
Subscriber's behalf, purchases (in an open market transaction or otherwise)
shares of common stock to deliver in satisfaction of a sale by such Subscriber
of the shares of Common Stock which the Subscriber was entitled to receive from
the Company (a "BUY-IN"), then the Company shall pay in cash to the Subscriber
(in addition to any remedies available to or elected by the Subscriber) the
amount by which (A) the Subscriber's total purchase price (including brokerage
commissions, if any) for the shares of common stock so purchased exceeds (B) the
aggregate purchase price of the shares of Common Stock delivered to the Company
for reissuance as Unlegended Shares together with interest thereon at a rate of
15% per annum, accruing until such amount and any accrued interest thereon is
paid in full (which amount shall be paid as liquidated damages and not as a
penalty). For example, if a Subscriber purchases shares of Common Stock having a
total purchase price of $11,000 to cover a Buy-In with respect to $10,000 of

                                       23

purchase price of shares of Common Stock delivered to the Company for reissuance
as Unlegended Shares, the Company shall be required to pay the Subscriber
$1,000, plus interest. The Subscriber shall provide the Company written notice
indicating the amounts payable to the Subscriber in respect of the Buy-In.

                           (e) In the event a Subscriber shall request delivery
of Unlegended Shares as described in Section 11.7 and the Company is required to
deliver such Unlegended Shares pursuant to Section 11.7, the Company may not
refuse to deliver Unlegended Shares based on any claim that such Subscriber or
any one associated or affiliated with such Subscriber has been engaged in any
violation of law, or for any other reason, unless, an injunction or temporary
restraining order from a court, on notice, restraining and or enjoining delivery
of such Unlegended Shares or exercise of all or part of said Warrant shall have
been sought and obtained by the Company or at the Company's request or with the
Company's assistance, and the Company has posted a surety bond for the benefit
of such Subscriber in the amount of 120% of the amount of the aggregate purchase
price of the Common Stock and Warrant Shares which are subject to the injunction
or temporary restraining order, which bond shall remain in effect until the
completion of arbitration/litigation of the dispute and the proceeds of which
shall be payable to such Subscriber to the extent Subscriber obtains judgment in
Subscriber's favor.

                  12. (a) RIGHT OF FIRST REFUSAL. Prior to the two-year
anniversary of the date of this Agreement, each Subscriber owning any Note
principal shall be given not less than seven (7) business days prior written
notice of any proposed sale by the Company of its common stock or other
securities or debt obligations, except in connection with (i) full or partial
consideration in connection with a strategic merger, acquisition, consolidation
or purchase of substantially all of the securities or assets of corporation or
other entity which holders of such securities or debt are not at any time
granted registration rights, (ii) the Company's issuance of securities in
connection with strategic license agreements and other partnering arrangements
so long as such issuances are not for the purpose of raising capital which
holders of such securities or debt are not at any time granted registration
rights, (iii) the Company's issuance of Common Stock or the issuances or grants
of options to purchase Common Stock pursuant to stock option plans and employee
stock purchase plans described on SCHEDULE 5(D) hereto at prices equal to or
higher than the closing price of the Common Stock on the issue date of any of
the foregoing and in the aggregate up to an amount of Common Stock equal to ten
percent of the outstanding Common Stock immediately following the Closing in a
fully-diluted basis, (iv) as a result of the exercise of Warrants or conversion
of Notes which are granted or issued pursuant to this Agreement or that have
been issued prior to the Closing Date, the issuance of which has been disclosed
in a Report filed not less than five (5) days prior to the Closing Date, (v) the
payment of any interest on the Notes and liquidated damages or other damages
pursuant to the Transaction Documents or other securities instruments that have
been issued prior to the Closing Date, the issuance of which has been disclosed
in a Report filed not less than five days prior to the Closing Date, and (vi) as
described on SCHEDULE 12(A) hereto(collectively the foregoing are "EXCEPTED
ISSUANCES"). The Subscribers who exercise their rights pursuant to this Section
12(a) shall have the right during the seven (7) business days following receipt
of the notice to purchase such offered common stock, debt or other securities in
accordance with the terms and conditions set forth in the notice of sale in the
same proportion to each other as the amount of Note principal owned by them on
the date the above-described notice is given. In the event such terms and
conditions are modified during the notice period, the Subscribers shall be given
prompt notice of such modification and shall have the right during the seven (7)
business days following the notice of modification to exercise such right.

                           (b) FAVORED NATIONS PROVISION. Other than in
connection with the Excepted Issuances, if at any time Notes or Warrants are
outstanding, and as limited in connection with the Warrants and Warrants Shares
to the time periods set forth in Section 3.4 of the Warrant, the Company shall
offer, issue or agree to issue any common stock or securities convertible into
or exercisable for shares of common stock (or modify any of the foregoing which
may be outstanding) to any person or entity at a price per share or conversion
or exercise price per share which shall be less than the Conversion Price in
respect of the Shares, or if less than the Warrant exercise price in respect of
the Warrant Shares, without the consent of each Subscriber holding Notes,

                                       24

Shares, Warrants, or Warrant Shares, then the Company shall issue, for each such
occasion, additional shares of Common Stock to each Subscriber so that the
average per share purchase price of the shares of Common Stock issued to the
Subscriber (of only the Common Stock or Warrant Shares still owned by the
Subscriber) is equal to such other lower price per share and the Conversion
Price and Warrant exercise price shall automatically be adjusted as provided in
the Notes and the Warrants. The average Purchase Price of the Shares and average
exercise price in relation to the Warrant Shares shall be calculated separately
for the Shares and Warrant Shares. The foregoing calculation and issuance shall
be made separately for Shares received upon conversion and separately for
Warrant Shares. The delivery to the Subscriber of the additional shares of
Common Stock shall be not later than the closing date of the transaction giving
rise to the requirement to issue additional shares of Common Stock. The
Subscriber is granted the registration rights described in Section 11 hereof in
relation to such additional shares of Common Stock except that the Filing Date
and Effective Date vis-a-vis such additional common shares shall be,
respectively, the thirtieth (30th) and sixtieth (60th) date after the closing
date giving rise to the requirement to issue the additional shares of Common
Stock. For purposes of the issuance and adjustment described in this paragraph,
the issuance of any security of the Company carrying the right to convert such
security into shares of Common Stock or of any warrant, right or option to
purchase Common Stock shall result in the issuance of the additional shares of
Common Stock upon the sooner of the agreement to or actual issuance of such
convertible security, warrant, right or option and again at any time upon any
subsequent issuances of shares of Common Stock upon exercise of such conversion
or purchase rights if such issuance is at a price lower than the Conversion
Price or Warrant exercise price in effect upon such issuance. The rights of the
Subscriber set forth in this Section 12 are in addition to any other rights the
Subscriber has pursuant to this Agreement, the Note, any Transaction Document,
and any other agreement referred to or entered into in connection herewith.

                           (c) MAXIMUM EXERCISE OF RIGHTS. In the event the
exercise of the rights described in Sections 12(a) and 12(b) would or could
result in the issuance of an amount of common stock of the Company that would
exceed the maximum amount that may be issued to a Subscriber calculated in the
manner described in Section 7.3 of this Agreement, then the issuance of such
additional shares of common stock of the Company to such Subscriber will be
deferred in whole or in part until such time as such Subscriber is able to
beneficially own such common stock without exceeding the applicable maximum
amount set forth calculated in the manner described in Section 7.3 of this
Agreement. The determination of when such common stock may be issued shall be
made by each Subscriber as to only such Subscriber.

                  13.  MISCELLANEOUS.

                           (b) ENTIRE AGREEMENT; ASSIGNMENT. This Agreement and
other documents delivered in connection herewith represent the entire agreement
between the parties hereto with respect to the subject matter hereof and may be
amended only by a writing executed by approval or written consent of
Subscribers, as defined in subparagraph (h) hereof. Neither the Company nor the
Subscribers have relied on any representations not contained or referred to in
this Agreement and the documents delivered herewith. No right or obligation of
the Company shall be assigned without prior notice to and the written consent of
the Subscribers.

                           (c) COUNTERPARTS/EXECUTION. This Agreement may be
executed in any number of counterparts and by the different signatories hereto
on separate counterparts, each of which, when so executed, shall be deemed an
original, but all such counterparts shall constitute but one and the same
instrument. This Agreement may be executed by facsimile signature and delivered
by facsimile transmission.

                           (d) LAW GOVERNING THIS AGREEMENT. This Agreement
shall be governed by and construed in accordance with the laws of the State of
New York without regard to conflicts of laws principles that would result in the
application of the substantive laws of another jurisdiction. Any action brought
by either party against the other concerning the transactions contemplated by
this Agreement shall be brought only in the civil or state courts of New York or
in the federal courts located in New York County. THE PARTIES AND THE
INDIVIDUALS EXECUTING THIS AGREEMENT AND OTHER AGREEMENTS REFERRED TO HEREIN OR
DELIVERED IN CONNECTION HEREWITH ON BEHALF OF THE COMPANY AGREE TO SUBMIT TO THE
JURISDICTION OF SUCH COURTS AND WAIVE TRIAL BY JURY. The prevailing party shall
be entitled to recover from the other party its reasonable attorney's fees and
costs. In the event that any provision of this Agreement or any other agreement
delivered in connection herewith is invalid or unenforceable under any
applicable statute or rule of law, then such provision shall be deemed
inoperative to the extent that it may conflict therewith and shall be deemed
modified to conform with such statute or rule of law. Any such provision which
may prove invalid or unenforceable under any law shall not affect the validity
or enforceability of any other provision of any agreement.

                           (e) SPECIFIC ENFORCEMENT, CONSENT TO JURISDICTION. To
the extent permitted by law, the Company and Subscriber acknowledge and agree
that irreparable damage would occur in the event that any of the provisions of
this Agreement were not performed in accordance with their specific terms or
were otherwise breached. It is accordingly agreed that the parties shall be
entitled to one or more preliminary and final injunctions to prevent or cure
breaches of the provisions of this Agreement and to enforce specifically the
terms and provisions hereof, this being in addition to any other remedy to which
any of them may be entitled by law or equity. Subject to Section 13(d) hereof,
each of the Company, Subscriber and any signatory hereto in his personal
capacity hereby waives, and agrees not to assert in any such suit, action or
proceeding, any claim that it is not personally subject to the jurisdiction in
New York of such court, that the suit, action or proceeding is brought in an
inconvenient forum or that the venue of the suit, action or proceeding is
improper. Nothing in this Section shall affect or limit any right to serve
process in any other manner permitted by law.

                           (f) DAMAGES. In the event the Subscriber is entitled
to receive any liquidated damages pursuant to the Transactions, the Subscriber
may elect to receive the greater of actual damages or such liquidated damages.

                           (g) INDEPENDENT NATURE OF SUBSCRIBERS. The Company
acknowledges that the obligations of each Subscriber under the Transaction
Documents are several and not joint with the obligations of any other

                                       26

Subscriber, and no Subscriber shall be responsible in any way for the
performance of the obligations of any other Subscriber under the Transaction
Documents. The Company acknowledges that each Subscriber has represented that
the decision of each Subscriber to purchase Securities has been made by such
Subscriber independently of any other Subscriber and independently of any
information, materials, statements or opinions as to the business, affairs,
operations, assets, properties, liabilities, results of operations, condition
(financial or otherwise) or prospects of the Company which may have been made or
given by any other Subscriber or by any agent or employee of any other
Subscriber, and no Subscriber or any of its agents or employees shall have any
liability to any Subscriber (or any other person) relating to or arising from
any such information, materials, statements or opinions. The Company
acknowledges that nothing contained in any Transaction Document, and no action
taken by any Subscriber pursuant hereto or thereto (including, but not limited
to, the (i) inclusion of a Subscriber in the Registration Statement and (ii)
review by, and consent to, such Registration Statement by a Subscriber) shall be
deemed to constitute the Subscribers as a partnership, an association, a joint
venture or any other kind of entity, or create a presumption that the
Subscribers are in any way acting in concert or as a group with respect to such
obligations or the transactions contemplated by the Transaction Documents. The
Company acknowledges that each Subscriber shall be entitled to independently
protect and enforce its rights, including without limitation, the rights arising
out of the Transaction Documents, and it shall not be necessary for any other
Subscriber to be joined as an additional party in any proceeding for such
purpose. The Company acknowledges that it has elected to provide all Subscribers
with the same terms and Transaction Documents for the convenience of the Company
and not because Company was required or requested to do so by the Subscribers.
The Company acknowledges that such procedure with respect to the Transaction
Documents in no way creates a presumption that the Subscribers are in any way
acting in concert or as a group with respect to the Transaction Documents or the
transactions contemplated thereby.

                           (h) CONSENT. As used in the Agreement, "consent of
the Subscribers" or similar language means the consent of holders of not less
than 75% of the total of the Shares issued and issuable upon conversion of
outstanding Notes owned by Subscribers on the date consent is requested.

                           (i) EQUAL TREATMENT. No consideration shall be
offered or paid to any person to amend or consent to a waiver or modification of
any provision of the Transaction Documents unless the same consideration is also
offered and paid to all the parties to the Transaction Documents.

CONVERTIBLE NOTE

         FOR VALUE RECEIVED, CEPTOR CORPORATION, a Delaware corporation
(hereinafter called "Borrower"), hereby promises to pay to
___________________________,
_____________________________________________________________________ (the
"Holder") or order, without demand, the sum of
______________________________________ Dollars ($__________), with simple
interest accruing thereon, on May ____, 2007 (the "Maturity Date"), if not paid
sooner.

         This Note has been entered into pursuant to the terms of a subscription
agreement between the Borrower and the Holder, dated of even date herewith (the
"Subscription Agreement"), and shall be governed by the terms of such
Subscription Agreement. Unless otherwise separately defined herein, all
capitalized terms used in this Note shall have the same meaning as is set forth
in the Subscription Agreement. The following terms shall apply to this Note:

                                    ARTICLE I

                               GENERAL PROVISIONS

         1.1 Payment Grace Period. The Borrower shall have a ten (10) business
day grace period to pay any monetary amounts due under this Note, after which
grace period and during the pendency of an Event of Default (as defined in
Article III) a default interest rate of twelve percent (12%) per annum shall
apply to the amounts owed hereunder.

         1.2 Conversion Privileges. The Conversion Privileges set forth in
Article II shall remain in full force and effect immediately from the date
hereof and until the Note is paid in full regardless of the occurrence of an
Event of Default. The Note shall be payable in full on the Maturity Date, unless
previously converted into Common Stock in accordance with Article II hereof;
provided, that if an Event of Default has occurred that has not been timely
cured, the Holder may extend the Maturity Date an amount of time equal to the
duration of the Event of Default.

         1.3 Interest Rate. Simple interest payable on this Note shall accrue at
the annual rate of six percent (6%) and be payable at the request of the Holder
upon or after each conversion of principal pursuant to Article II, and on the
Maturity Date, accelerated or otherwise, when the principal and remaining
accrued but unpaid interest shall be due and payable, or sooner as described
below.

                                   ARTICLE II

                               CONVERSION RIGHTS

         The Holder shall have the right to convert the principal due under this
Note into Shares of the Borrower's Common Stock, $0.0001 par value per share
("Common Stock") as set forth below.

         2.1. Conversion into the Borrower's Common Stock.

         (a) The Holder shall have the right from and after the issuance of this
Note and then at any time until this Note is fully paid, to convert any
outstanding and unpaid principal portion of this Note, at the election of the
Holder (the date of giving of such notice of conversion being a "Conversion
Date") into fully paid and nonassessable shares of Common Stock as such stock
exists on the date of issuance of this Note, or any shares of capital stock of
Borrower into which such Common Stock shall hereafter be changed or
reclassified, at the conversion price as defined in Section 2.1(b) hereof (the
"Conversion Price"), determined as provided herein. Upon delivery to the
Borrower of a completed Notice of Conversion, a form of which is annexed hereto,
Borrower shall issue and deliver to the Holder within three (3) business days
after the Conversion Date (such third day being the "Delivery Date") that number
of shares of Common Stock for the portion of the Note converted in accordance
with the foregoing. The number of shares of Common Stock to be issued upon each
conversion of this Note shall be determined by dividing that portion of the
principal of the Note to be converted, by the Conversion Price.

         (b) Subject to adjustment as provided in Section 2.1(c) hereof, the
Conversion Price per share shall be the lesser of (i) $0.15 ("Maximum Base
Price"), or (ii) ninety percent (90%) of the lowest closing sales price of the
Common Stock as reported by Bloomberg L.P. for the Principal Market for the
twenty trading days preceding the Conversion Date. In the event there is no
reported lowest closing sales price during such twenty days, then the average of
the closing bid and ask prices during such period shall be employed in lieu
thereof. Until September 30, 2005, the Conversion Price will not be less than
$0.15, subject to adjustment as described herein.

         (c) The Conversion Price and number and kind of shares or other
securities to be issued upon conversion determined pursuant to Section 2.1(a),
shall be subject to adjustment from time to time upon the happening of certain
events while this conversion right remains outstanding, as follows:

                  A. Merger, Sale of Assets, etc. If the Borrower at any time
shall consolidate with or merge into or sell or convey all or substantially all
its assets to any other corporation, this Note, as to the unpaid principal
portion thereof and accrued interest thereon, shall thereafter be deemed to
evidence the right to purchase such number and kind of shares or other
securities and property as would have been issuable or distributable on account
of such consolidation, merger, sale or conveyance, upon or with respect to the
securities subject to the conversion or purchase right immediately prior to such
consolidation, merger, sale or conveyance. The foregoing provision shall
similarly apply to successive transactions of a similar nature by any such
successor or purchaser. Without limiting the generality of the foregoing, the
anti-dilution provisions of this Section shall apply to such securities of such
successor or purchaser after any such consolidation, merger, sale or conveyance.

                  B. Reclassification, etc. If the Borrower at any time shall,
by reclassification or otherwise, change the Common Stock into the same or a
different number of securities of any class or classes that may be issued or

outstanding, this Note, as to the unpaid principal portion thereof and accrued
interest thereon, shall thereafter be deemed to evidence the right to purchase
an adjusted number of such securities and kind of securities as would have been
issuable as the result of such change with respect to the Common Stock
immediately prior to such reclassification or other change.

                  C. Stock Splits, Combinations and Dividends. If the shares of
Common Stock are subdivided or combined into a greater or smaller number of
shares of Common Stock, or if a dividend is paid on the Common Stock in shares
of Common Stock, the Conversion Price shall be proportionately reduced in case
of subdivision of shares or stock dividend or proportionately increased in the
case of combination of shares, in each such case by the ratio which the total
number of shares of Common Stock outstanding immediately after such event bears
to the total number of shares of Common Stock outstanding immediately prior to
such event..

                  D. Share Issuance. For such portion of the Note which remains
outstanding and not converted, if the Borrower shall issue or agree to issue any
shares of Common Stock except for the Excepted Issuances (as defined in the
Subscription Agreement) for a consideration less than the Maximum Base Price in
effect at the time of such issue, then, and thereafter successively upon each
such issue, the Maximum Base Price shall be reduced to such other lower issue
price. For purposes of this adjustment, the issuance of any security carrying
the right to convert such security into shares of Common Stock or of any
warrant, right or option to purchase Common Stock shall result in an adjustment
to the Maximum Base Price upon the issuance of the above-described security and
again upon the issuance of shares of Common Stock upon exercise of such
conversion or purchase rights if such issuance is at a price lower than the then
applicable Maximum Base Price. The reduction of the Maximum Base Price described
in this paragraph is in addition to other rights of the Holder described in this
Note and the Subscription Agreement.

         (d) Whenever the Conversion Price is adjusted pursuant to Section
2.1(c) above, the Borrower shall promptly mail to the Holder a notice setting
forth the Conversion Price after such adjustment and setting forth a statement
of the facts requiring such adjustment.

         (e) Borrower will reserve from its authorized and unissued Common Stock
the number of shares of Common Stock during the time periods and in the amounts
described in the Subscription Agreement. Borrower represents that upon issuance,
such shares will be duly and validly issued, fully paid and non-assessable.
Borrower agrees that its issuance of this Note shall constitute full authority
to its officers, agents, and transfer agents who are charged with the duty of
executing and issuing stock certificates to execute and issue the necessary
certificates for shares of Common Stock upon the conversion of this Note.

         2.2 Method of Conversion. This Note may be converted by the Holder in
whole or in part as described in Section 2.1(a) hereof and the Subscription
Agreement. Upon partial conversion of this Note, a new Note containing the same
date and provisions of this Note shall, at the request of the Holder, be issued
by the Borrower to the Holder for the principal balance of this Note and
interest which shall not have been converted or paid.

         2.3 Maximum Conversion. The Holder shall not be entitled to convert on
a Conversion Date that amount of the Note in connection with that number of
shares of Common Stock which would be in excess of the sum of (i) the number of
shares of Common Stock beneficially owned by the Holder and its affiliates on a
Conversion Date, (ii) any Common Stock issuable in connection with the
unconverted portion of the Note, and (iii) the number of shares of Common Stock
issuable upon the conversion of the Note with respect to which the determination
of this provision is being made on a Conversion Date, which would result in
beneficial ownership by the Holder and its affiliates of more than 4.99% of the
outstanding shares of Common Stock of the Borrower on such Conversion Date. For

the purposes of the provision to the immediately preceding sentence, beneficial
ownership shall be determined in accordance with Section 13(d) of the Securities
Exchange Act of 1934, as amended, and Regulation 13d-3 thereunder. Subject to
the foregoing, the Holder shall not be limited to aggregate conversions of only
4.99% and aggregate conversion by the Holder may exceed 4.99%. The Holder shall
have the authority and obligation to determine whether the restriction contained
in this Section 2.3 will limit any conversion hereunder and to the extent that
the Holder determines that the limitation contained in this Section applies, the
determination of which portion of the Notes are convertible shall be the
responsibility and obligation of the Holder. The Holder may waive the conversion
limitation described in this Section 2.3, in whole or in part, upon and
effective after 61 days prior written notice to the Borrower to increase such
percentage to up to 9.99%. The Holder may allocate which of the equity of the
Borrower deemed beneficially owned by the Holder shall be included in the 4.99%
amount or up to 9.99% amount as described above.

         2.4. Optional Redemption of Principal Amount. Provided an Event of
Default or an event that with the passage of time or the giving of notice could
become an Event of Default is not pending, then commencing on the Issue Date and
ending September 30, 2006, the Borrower will have the option of prepaying the
outstanding Principal Amount ("Optional Redemption"), in whole or in part, by
paying to the Holder a sum of money equal to two hundred percent (200%) of the
Principal amount to be redeemed, together with accrued but unpaid interest
thereon and any and all other sums due, accrued or payable to the Holder arising
under this Note, the Subscription Agreement or any Transaction Document through
the Redemption Payment Date as defined below (the "Redemption Amount").
Borrower's election to exercise its right to prepay must be by notice in writing
("Notice of Redemption"). The Notice of Redemption shall specify the date for
such Optional Redemption (the "Redemption Payment Date"), which date shall be
thirty (30) business days after delivery of the Notice of Redemption (the
"Redemption Period"). A Notice of Redemption shall not be effective with respect
to any portion of the Principal Amount for which the Holder has a pending
election to convert pursuant to Section 2.1, or for conversions initiated or
made by the Holder pursuant to Section 2.1 during the Redemption Period. The
amount of Note principal included in a Notice of Redemption shall be reduced to
an amount that would not cause the Holder to exceed the limitation described in
Section 2.3 of this Note if the amount of Note Principal being redeemed was
instead converted pursuant to Section 2.1. On the Redemption Payment Date, the
Redemption Amount less any portion of the Redemption Amount against which the
Holder has exercised its rights pursuant to Section 2.1, shall be paid in good
funds to the Holder. In the event the Borrower fails to pay the Redemption
Amount on the Redemption Payment Date as set forth herein, then (i) such Notice
of Redemption will be null and void, (ii) Borrower will have no right to deliver
another Notice of Redemption, and (iii) Borrower's failure may be deemed by
Holder to be a non-curable Event of Default as of the Redemption Payment Date.
Notices of Redemption must be given to all Holders of Notes similar in term and
tenure as this Note, in proportion to the respective Principal Amounts
outstanding on the date Notice of Redemption is given. In the event Borrower
publicly announces or discloses on or before September 30, 2006 the sale or
merger of the Company or of its principal assets and consummates such
transaction within six months after such announcement, then the Holder of this
Note may for himself, without limitation as to amount of Note principal,
exercise on the Borrower's behalf the redemption rights described in this
Section 2.4 by delivery to the Borrower of a Notice of Redemption but only in
relation to the amount of Note principal held by such Holder as to itself only
on the closing date of the announced transaction. Except as described in this
Section 2.4, the Note may not be paid prior to the Maturity Date without the
consent of the Holder.

                                   ARTICLE III

                                EVENT OF DEFAULT

         The occurrence of any of the following events of default ("Event of
Default") shall, at the option of the Holder hereof, make all sums of principal

grace period, all of which hereby are expressly waived, except as set forth
below:

installment of principal, interest or other sum due under this Note when due and

business day period described in Section 1.1 hereof.

         3.2 Breach of Covenant. The Borrower breaches any material covenant or

         3.3 Breach of Representations and Warranties. Any material
representation or warranty of the Borrower made herein, in the Subscription
Agreement, or in any agreement, statement or certificate given in writing
pursuant hereto or in connection therewith shall be false or misleading in any
material respect as of the date made and the Closing Date.

         3.4 Receiver or Trustee. The Borrower shall make an assignment for the
benefit of creditors, or apply for or consent to the appointment of a receiver
or trustee for it or for a substantial part of its property or business; or such
a receiver or trustee shall otherwise be appointed without the consent of the
Borrower is not dismissed within sixty (60) days of appointment.

shall remain unpaid, unvacated, unbonded or unstayed for a period of forty-five
(45) days.

         3.6 Bankruptcy. Bankruptcy, insolvency, reorganization or liquidation

validity of such obligation in good faith, or except as described on Schedule
5(q) to the Subscription Agreement, or except for obligations where the Borrower
and creditor have agreed to alternative payment terms.

         3.9 Stop Trade. An SEC or judicial stop trade order or Principal Market

         3.10 Failure to Deliver Common Stock or Replacement Note. Borrower's
failure to timely deliver Common Stock to the Holder pursuant to and in the form
required by this Note and Sections 7 and 11 of the Subscription Agreement, or,

delivery date or any stated cure period, whichever is later.

         3.11 Non-Registration Event. The occurrence of a Non-Registration Event

                                   ARTICLE IV

                                  MISCELLANEOUS
