         This Note has been entered into pursuant to the terms of a Subscription
Agreement between the Borrower, the Holder and certain other subscribers of the
Borrower's convertible notes, 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 five (5) 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 fifteen percent (15%) per annum shall
apply to the amounts owed hereunder.

         1.2. Interest Rate. Simple interest payable on this Note shall accrue
              -------------
at the annual rate of six percent (6%). Accrued interest will be payable on each
annual anniversary of the Issue Date and on the Maturity Date, accelerated or
otherwise, when the principal and remaining accrued but unpaid interest shall be
due and payable. Interest will be payable in cash or at the election of the
Borrower, unless an Event of Default has occurred and has not been timely cured,
by the Borrower's delivery of either registered shares of Common Stock or Common
Stock which may be resold immediately pursuant to Rule 144(b)(1)(i) of the
Securities Act of 1933, as amended ("Interest Shares") valued at the Conversion
Price in effect on the day the interest

<PAGE>

payment is due. In no event may Interest Shares be paid by the Borrower to the
extent such Interest Shares would exceed the limitation set forth in Section 2.3
of this Note.

         1.3. Conversion Privileges. The conversion rights of the Holder as set
              ---------------------
forth in Article II of this Note 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 principal amount of the Note and
the remaining accrued but unpaid interest shall be payable in full on the
Maturity Date, unless previously paid or converted into Common Stock in
accordance with Article II hereof.

                                   ARTICLE II

                                CONVERSION RIGHTS

         The Holder shall have the right to convert the entire principal amount
under this Note and the accrued but unpaid interest thereon into shares of the
Borrower's Common Stock as set forth below.

         2.1. Voluntary Conversion into the Borrower's Common Stock.
              -----------------------------------------------------

             (a) The Holder shall have the right from and after the Issue Date
of 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 (provided
that any partial conversion shall not be for a portion of the principal amount
of this Note which is the lesser of (i) $25,000, or (ii) the remaining balance
of the principal amount 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 for in Section 2.1(c) hereof,
the Conversion Price per share of Common Stock shall be $0.15 ("Conversion
Price").

             (c) The Conversion Price and the number and kind of shares or other
securities to be issued upon conversion of this Note, 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

                                       2
<PAGE>

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 or
surviving entity of the surviving corporation 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 of the Borrower's capital
stock that may be issued or outstanding, this Note, as to the unpaid principal
amount 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 shares of Common Stock subject to the conversion of this Note 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. So long as this Note is outstanding, if the
                    --------------
Borrower shall issue or agree to issue any shares of Common Stock other than
with respect to any Excepted Issuances for a consideration less than the
Conversion Price in effect at the time of such issue, then, and thereafter
successively upon each such issue, the Conversion 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 Conversion 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 Conversion Price. The reduction of the Conversion 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 provide notice to the Holder setting
forth the Conversion Price after such adjustment and setting forth a statement
of the facts requiring such adjustment.

                                       3
<PAGE>

             (e) The Borrower will reserve from its authorized and unissued
shares of Common Stock, the number of shares of Common Stock during the time
periods and in the amounts described in the Subscription Agreement. The Borrower
represents that upon issuance, such shares of Common Stock will be duly and
validly issued, fully paid and non-assessable. The 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 the
Borrower's Common Stock upon the conversion of this Note.

         2.2 No Fractional Shares. No fractional shares of Common Stock shall be
             --------------------
issued upon conversion of this Note, but an adjustment in cash will be made, in
respect of any fraction of a share (which will be valued based on the Conversion
Price) which would otherwise be issuable upon the surrender of this Note for
conversion and a check in the amount of the value of such fractional share shall
be delivered to the Holder.

         2.3 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.

         2.4 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, 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 Holder and its affiliates of more than 4.99% of the issued and
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 the amount of the Note which is convertible shall be the
responsibility and obligation of the Holder. The Holder may increase the
permitted beneficial ownership amount up to 9.99% upon and effective after 61
days prior written notice to the Company. 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 described above and which shall be allocated to the excess
above 4.99%.

         2.5. Mandatory Conversion. Unless an Event of Default (or an event that
              --------------------
with the passage of time or the giving of notice could become an Event of
Default, has occurred and has not been timely cured, then commencing after the
Actual Effective Date (as defined in Section 11.1(iv) of the Subscription
Agreement), the Borrower will have the option by written notice to the Holder
("Notice of Mandatory Conversion") of compelling the Holder to convert part or
all

                                       4
<PAGE>

of the outstanding and unpaid principal of this Note into Common Stock at the
Conversion Price then in affect ("Mandatory Conversion"). The Notice of
Mandatory Conversion may only be given, if at all, within five (5) business days
after the Borrower has received the net proceeds from an underwritten public
offering of the Borrower's equity securities in the gross amount of not less
than $30,000,000 at a per share equivalent price of not less than the Conversion
Price in effect on the final closing of such public offering ("Mandatory
Conversion Conditions"). The date the Notice of Mandatory Conversion is given is
the "Mandatory Conversion Date." The Notice of Mandatory Conversion shall
specify the aggregate principal amount of the Note which is subject to Mandatory
Conversion. Mandatory Conversion Notices must be given proportionately to all
Holders of Notes who received Notes similar in terms and tenure as this Note. A
Notice of Mandatory Conversion may not be given unless the Registration
Statement (as defined in the Subscription Agreement) is effective for the
unrestricted public resale of the Registrable Securities (as defined in the
Subscription Agreement) for each of the twenty trading days preceding the
Mandatory Conversion Date and through the date the conversion shares are
delivered to the Holder. The amount of Note principal included in a Mandatory
Redemption Notice shall be reduced to an amount that would not cause the Holder
to exceed the limitation described in Section 2.4 of this Note. Each Mandatory
Conversion Date shall be a deemed Conversion Date and the Borrower will be
required to deliver the Common Stock issuable pursuant to a Mandatory Conversion
Notice in the same manner and time period as described in Section 2.1 herein.

                                   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
and accrued interest then remaining unpaid hereon and all other amounts payable
hereunder immediately due and payable, upon demand, without presentment or grace
period, all of which hereby are expressly waived, except as set forth below:

         WHEREAS, the Company and the Subscribers are executing and delivering
this Agreement in reliance upon an exemption from securities registration
afforded by the provisions of Section 4(2), Section 4(6) and/or Regulation D
("Regulation D") as promulgated by the United States Securities and Exchange

         WHEREAS, the parties desire that, upon the terms and subject to the
conditions contained herein, the Company shall issue and sell to such

Stock (the "Warrant Shares"). The Notes, shares of Common Stock issuable upon

upon exercise of the Warrants are collectively referred to herein as the

         WHEREAS, the Purchase Price to be paid by the Subscribers and the Notes
and the Warrants to be issued by the Company as provided herein shall be held in
escrow pursuant to the terms of a Funds Escrow Agreement to be executed by the
parties substantially in the form attached hereto as Exhibit C (the "Escrow

agreements contained in this Agreement, the Company and the Subscribers hereby
agree as follows:

Suite 1601, New York, New York 10176, upon the satisfaction or waiver of all
conditions to closing set forth in this Agreement. Subject to the satisfaction
or waiver of the terms and conditions of this Agreement, on the Closing Date,
each Subscriber shall purchase and the Company shall sell to each Subscriber a
Note in the principal amount designated on the signature page hereto for the

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 such Subscriber contained

laws or is exempt from such registration. Subject to compliance with applicable

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 or the Company's ability to timely comply with its
obligations hereunder. Neither the Company nor any of its Subsidiaries will take
any action or steps that would 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 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
                 -----------------------

                 --------------------------
obligations which are material, individually or in the aggregate, which are not

                                       9
<PAGE>

reasonably be expected not to have a Material Adverse Effect, except as
disclosed on Schedule 5(q).

             (r) No Undisclosed Events or Circumstances. Since December 31,
                 --------------------------------------

             (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 and its shareholders. 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 stockholders of the Company or parties entitled to
receive equity of the Company.

             (u) No Disagreements with Accountants and Lawyers. There are no
                 ---------------------------------------------

             (w) Investment Company. Neither the Company nor any Affiliate is an

                 --------
the Closing Date after giving effect to the receipt by the Company of the
proceeds from the sale of the Securities hereunder, (i) the Company's fair
saleable value of its assets exceeds the amount that will be required to be paid

(including known contingent liabilities) as they mature; and (ii) the current
cash flow of the Company, together with the proceeds the Company would receive,
were it to liquidate all of its assets, after taking into account all
anticipated uses of the cash, would be sufficient to pay all amounts on or in
respect of its debt when such amounts are required to be paid.

Subsidiary of the Company; provided that with respect to the Company's former
wholly-owned subsidiary, Email Emissary, Inc., which has been dissolved, the
Company makes no representation or warranties other than that such subsidiary
has no material assets or liabilities and did not conduct any active business
operations during 2007.

             (AA) Company Predecessor. All representations made by or relating
                  -------------------

                  ------------------------------
the foregoing representations and warranties are true and correct as of the date

respects as of the Closing Date.

             (CC) Survival. The foregoing representations and warranties shall
                  --------
survive the Closing Date.

         6. Regulation D Offering/Legal Opinion. 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 such
Subscribers from the Company's legal counsel in the form annexed hereto as
Exhibit D 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 the Subscribers. 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 pursuant to an effective registration statement, Rule
144 under the 1933 Act or an exemption from registration.

                                       11

         7.1 Conversion of Note.
             ------------------

             (a) Upon the conversion of a Note or part thereof as provided for
in Section 2.1(a) of the Note, the Company shall, at its own cost and expense,
take all necessary action, including obtaining and delivering, an opinion of
counsel to assure that the Company's transfer agent shall issue stock
certificates in the name of a Subscriber (or its permitted nominee) or such
other persons as designated by such 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. Examples of such legends are provided for in Section 4 of this
Agreement. If and when a Subscriber sells the Shares, assuming (i) a
registration statement including such Shares is effective and the prospectus, as
supplemented or amended, contained therein is current and (ii) such Subscriber
or its agent confirms in writing to the transfer agent that such Subscriber has
complied with the prospectus delivery requirements, the restrictive legend can
be removed and the Shares 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 in
accordance with the relevant provisions of Rule 144 of the 1933 Act).

             (b) Subscriber will give notice of its decision to exercise its
right to convert the Note, or part thereof as provided for in Section 2.1(a) of
the Note 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 such 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 fifth 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 such Subscriber
and such 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 a Subscriber if requested by
such Subscriber, provided such 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 of a Note, such 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.

             (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 a Subscriber. As

                                       12
<PAGE>

compensation to such Subscriber for such loss, the Company agrees to pay (as
liquidated damages and not as a penalty) to such 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 such 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, such
Subscriber will be entitled to 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
such Subscriber shall each be 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) The Company agrees and acknowledges that despite the pendency
of a not yet effective registration statement which includes for registration
the Securities, the Subscriber is permitted to and the Company will issue to the
Subscriber Shares upon conversion of the Note and Warrant Shares upon exercise
of the Warrants. Such Shares will, if required by law, bear the legends
described in Section 4 above and if the requirements of Rule 144 under the 1933
Act are satisfied be immediately resalable thereunder.

         7.2 Mandatory Redemption at Subscriber's Election. In the event (a) the
             ---------------------------------------------
Company is prohibited from issuing Shares, (b) fails to timely deliver Shares on
a Delivery Date, (c) upon the occurrence of any other Event of Default (as
defined in the Note or in this Agreement); any of the foregoing that is not
cured during any applicable cure period and an additional twenty (20) days
thereafter, or (d) upon a Change in Control (as defined below), then at such
Subscriber's election, the Company must pay to such Subscriber ten (10) business
days after request by such Subscriber, at such Subscriber's election, a sum of
money determined by (i) multiplying up to the outstanding principal amount of
the Note designated by such Subscriber by 100%, or (ii) multiplying the number
of Shares otherwise deliverable upon conversion of an amount of Note principal
and/or interest designated by such Subscriber (with the date of giving of such
designation being a "Deemed Conversion Date") at the Conversion Price that would
be in effect on the Deemed Conversion Date by the highest closing price of the
Common Stock on the Principal Market for the period commencing on the Deemed
Conversion Date until the day prior to the receipt of the Mandatory Redemption
Payment, whichever is greater; together with accrued but unpaid interest thereon
and any other sums arising and outstanding under the Transaction Documents
("Mandatory Redemption Payment"). The Mandatory Redemption Payment must be
received by such Subscriber within ten (10) business days after request
("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. "Change in Control" shall mean (i) the Company no longer
having a class of shares publicly traded or listed on a Principal Market (as
hereinafter defined), (ii) the Company becoming a Subsidiary of another entity
or merging into or with another entity, (iii) if Mr. Darin M. Myman beneficially
owns and holds at any time after the Closing Date less than ten percent (10%) of
the Company's Common stock, or (iv) the sale, lease, license or transfer of
substantially all the assets of the Company and its Subsidiaries.

                                       13
<PAGE>

         7.3 Maximum Conversion. A 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 (a) the number of
shares of Common Stock beneficially owned by such Subscriber and its Affiliates
on a Conversion Date, and (b) 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 such Subscriber and its Affiliates of more than 4.99% of the
outstanding shares of Common Stock of the Company 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 1934 Act
and Regulation 13d-3 thereunder. Subject to the foregoing, such Subscriber shall
not be limited to aggregate conversions of only 4.99% and aggregate conversions
by such Subscriber may exceed 4.99%. The Subscriber may increase the permitted
beneficial ownership amount up to 9.99% upon and effective after 61 days prior
written notice to the Company. The Subscriber may allocate which of the equity
of the Company deemed beneficially owned by such Subscriber shall be included in
the 4.99% amount described above and which shall be allocated to the excess
above 4.99%.

         7.4 Injunction Posting of Bond. In the event a Subscriber shall elect
             --------------------------
to convert a Note or part thereof, 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 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 which are sought to be
subject to the injunction, 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.

         7.5 Buy-In. In addition to any other rights available to a Subscriber,
             ------
if the Company fails to deliver to such Subscriber such shares issuable upon
conversion of a Note by the Delivery Date and if after seven (7) business days
after the Delivery Date such Subscriber or a broker on such 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
such Subscriber was entitled to receive upon such conversion (a "Buy-In"), then
the Company shall pay in cash to such Subscriber (in addition to any remedies
available to or elected by such Subscriber) the amount by which (A) such
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 such
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 to such
Subscriber $1,000, plus interest. The Subscriber shall provide the Company
written notice indicating the amounts payable to such Subscriber in respect of
the Buy-In.

         7.6 Adjustments. The Conversion Price, Warrant exercise price and the
             -----------
number of Shares issuable upon conversion of the Notes and Warrant Shares
issuable upon exercise of the Warrants shall be equitably adjusted and as
otherwise described in this Agreement, the Notes and Warrants.

         7.7 Redemption. The Note shall not be redeemable or callable except as
             ----------
described in the Note. The Warrants shall not be callable or redeemable.

         7.8 Mandatory Conversion. Unless an Event of Default (or an event that
             --------------------
with the passage of time or the giving of notice could become an Event of
Default (as such term is defined in the Notes)) has occurred and has not been
timely cured, then commencing after the effective date of a registration
statement contemplated by Section 11.1 hereof, the Company will have the option
by written notice to such Subscribers ("Notice of Mandatory Conversion") of
compelling such Subscribers to convert part or all of the outstanding and unpaid
principal of their Notes into Shares at the Conversion Price then in effect
("Mandatory Conversion"). The Notice of Mandatory Conversion may only be given,
if at all, within five (5) business days after the Company has received the net
proceeds from an underwritten public offering of the Company's equity securities
in the gross amount of not less than $30,000,000 at a per share equivalent price
of not less than the Conversion Price in effect on the final closing of such
public offering ("Mandatory Conversion Conditions" and such public offering
being the "Qualified Offering"). The date the Notice of Mandatory Conversion is
given is the "Mandatory Conversion Date." The Notice of Mandatory Conversion
shall specify the aggregate principal amount of the Notes which is subject to
Mandatory Conversion. Mandatory Conversion Notices must be given proportionately
to all Subscribers of Notes. A Notice of Mandatory Conversion may not be given
unless a registration statement (as contemplated in Section 11.1 of this
Agreement) is effective for the unrestricted public resale of the Securities for
each of the twenty (20) trading days preceding the Mandatory Conversion Date and
through the date the conversion shares are delivered to the Subscriber. The
amount of Note principal included in a Notice of Mandatory Conversion shall be
reduced to an amount that would not cause a Subscriber to exceed the limitation
described in Section 7.3 of this Agreement. Each Mandatory Conversion Date shall
be a deemed Conversion Date and the Company will be required to deliver the
Shares issuable pursuant to a Mandatory Conversion Notice in the same manner and
time period as described in Section 7.1(b) of this Agreement.

         8.  Finder/Legal Fees.
             -----------------

             (a) Finder. The Company on the one hand, and each Subscriber (for
himself, herself or itself 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 finder's fees on account of services
purported to have been rendered on behalf of the indemnifying party in
connection with this Agreement or the transactions contemplated hereby and
arising out of such party's actions. The Company and each Subscriber represents

             (e) Use of Proceeds. The proceeds of the Offering must be employed
                 ---------------

Price may not and will not be used for accrued and unpaid officer and director
salaries, payment of financing related debt, redemption of outstanding notes or
equity instruments of the Company or non-trade obligations outstanding on a

prepay any financing related debt obligations nor redeem any equity instruments

         --------
authorized but unissued Common Stock, a number of common shares equal to 100% of
the amount of Common Stock necessary to allow each holder of a Note to be able
to convert all such outstanding Notes and reserve the amount of Warrant Shares
issuable upon exercise of the Warrants. Failure to have sufficient shares
reserved pursuant to this Section 9(f) at any time 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 End Date,
                 -----
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 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 End
                 ---------

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

                                       17

customary for companies in similar businesses similarly situated and to the
extent available on commercially reasonable terms.

                 -----------------
the End Date, the Company will keep records and books of account in which

                 ------------------------
until the End Date, 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 End Date, the Company shall maintain in full force and effect its

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.

             (l) Properties. From the date of this Agreement and until the End
                 ----------
Date, 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 End Date, the Company agrees that except in connection
with a Form 8-K or any registration statement filed in connection herewith or as
otherwise required in connection with any other filing required to be made with
the Commission, 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.

Exhibit E.

             (n) Non-Public Information. The Company covenants and agrees that
                 ----------------------
except for schedules and exhibits to this Agreement which information thereon
will be publicly disclosed within four (4) business days after the Closing Date,
neither it nor any other person acting on its behalf will at any time 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.

                 (vi) the Company agrees to provide Subscribers not less than
ten (10) days notice prior to becoming obligated to or effectuating a Permitted
Lien or Excepted Issuance.

             (p) Further Registration Statements. Except for a registration
                 -------------------------------

             (q) Blackout. The Company undertakes and covenants that, until the
                 --------
end of the Exclusion Period, the Company will not enter into any acquisition,
merger, exchange or sale or other transaction or fail to take any action 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 for a period of twenty (20) or more days in the aggregate
during any three hundred and sixty-five (365) day period.

             (r) Equity Line Restrictions/Option Plans. For so long as the Notes
                 -------------------------------------
are outstanding, except for the Excepted Issuances, the Company will not enter

             (t) Seniority. Except for Permitted Liens and as otherwise provided

for herein, until the Notes are fully satisfied or converted, the Company shall
not grant nor allow any security interest to be taken in the assets of the
Company or any Subsidiary; nor issue any debt, equity or other instrument which
would give the holder thereof directly or indirectly, a right in

                                       20
<PAGE>

any assets of the Company or any Subsidiary, superior to any right of the holder
of a Note in or to such assets.

         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 upon (i) any material misrepresentation
by the Company or breach of any warranty by the Company in this Agreement or in
any Exhibits or Schedules attached hereto, or other Transaction Documents
delivered pursuant hereto, or (ii) after any applicable notice and/or cure
periods, any breach or default in performance by the Company of any covenant or
undertaking to be performed by the Company hereunder, or any other Transaction
Documents 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 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 Company or any such person which
results, arises out of or is based upon (i) any material misrepresentation by
such Subscriber in this Agreement or in any Exhibits or Schedules attached
hereto, or other Transaction Documents delivered pursuant hereto; or (ii) after
any applicable notice and/or cure periods, any breach or default in performance
by such Subscriber of any covenant or undertaking to be performed by such
Subscriber hereunder, or any other Transaction Documents 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
Securities.

             (d) The procedures set forth in Section 11.6 of the Subscription
Agreement ("Prior Subscription Agreement") employed in the Prior Offering shall
apply to the indemnification set forth in Sections 10(a) and 10(b) above.

         11.1. Registration Rights. The Company hereby grants to the holders of
               -------------------
the Securities the same registration rights granted to the Subscribers to the
Prior Offering as described in and related to Section 11.1(ii) of the Prior
Subscription Agreement. The Subscribers are granted the same notice remedies,
indemnification, liquidated damages and rights granted to the Subscribers to the
Prior Offering in connection with such registration rights and assume the same
obligations to the Company as such other subscribers under Section 11.1(ii) of
the Prior Subscription Agreement. Notwithstanding this Section 11.1, no
provisions regarding demand registration

                                       21
<PAGE>

rights contained in the Prior Subscription Agreement shall be applicable to the
holders of the Securities or otherwise incorporated herein.

         11.2. Delivery of Unlegended Shares.
               -----------------------------

             (a) Within three (3) business days (such third 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 registration
statement described in Section 11.1 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 (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 such 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 11.2 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 such
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 11.2
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) the actual purchase
price of such Shares or Warrant Shares, or (ii) the highest closing price of the
Common Stock during the aforedescribed thirty day period and the denominator of
which is the lowest conversion price during such thirty day period ("Unlegended
Redemption Amount"). The Company shall pay any payments incurred under this
Section in immediately available funds upon demand.

                                       22
<PAGE>

             (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 seven (7) business days after the Unlegended
Shares Delivery Date and a Subscriber or a broker on such 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 such Subscriber was entitled to receive from the Company (a
"Buy-In"), then the Company shall pay in cash to such Subscriber (in addition to
any remedies available to or elected by such Subscriber) the amount by which (A)
such 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 purchase
price of shares of Common Stock delivered to the Company for reissuance as
Unlegended Shares, the Company shall be required to pay such Subscriber $1,000,
plus interest. The Subscriber shall provide the Company written notice
indicating the amounts payable to such Subscriber in respect of the Buy-In.

             (e) In the event a Subscriber shall request delivery of Unlegended
Shares as described in Section 11.2 or Warrant Shares upon exercise of Warrants
and the Company is required to deliver such Unlegended Shares pursuant to
Section 11.2 or the Warrant Shares pursuant to the Warrants, the Company may not
refuse to deliver Unlegended Shares or Warrant 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.

         11.3. In the event commencing one hundred and eighty-one (181) days
after the Closing Date, a Subscriber is not permitted to resell any of the
Shares or Warrant Shares without any restrictive legend or if such sales are
permitted but subject to volume limitations or further restrictions on resale as
a result of the unavailability to Subscriber of Rule 144(b)(1)(i) under the 1933
Act or any successor rule (a "144 Default"), for any reason except for
Subscriber's status as an Affiliate or "control person" of the Company, then the
Company shall pay such Subscriber as liquidated damages and not as a penalty an
amount equal to two percent (2%) for each thirty (30) days (or such lesser
pro-rata amount for any period less than thirty (30) days) thereafter of the
purchase price of the Shares and Warrant Shares owned by such Subscriber during
the pendency of the 144 Default. Liquidated Damages that accrue pursuant to
Section 11.4 of the Prior Subscription Agreement and liquidated damages that
accrue pursuant to this Section 11.3 for contemporaneous periods shall be
payable only in connection with the higher of such

                                       23
<PAGE>

amounts (and not both of such amounts) as shall have accrued. Liquidated damages
shall not be payable pursuant to this Section 11.3 in connection with Shares and
Warrant Shares for such times as such Shares and Warrant Shares may be sold by
the holder thereof without restriction pursuant to Section 144(b)(1)(i) of the
1933 Act.

         12. (a) Right of First Refusal. Subject to the rights of the holders of
                 ----------------------
the Company's Series A Preferred Stock as existing and described in the Reports
as of the Closing Date and without any amendment or enlargement thereof and the
rights of the Subscribers to the Prior Offering, until one year after the Second
Closing Date (which period shall be tolled during the pendency of an Event of
Default that is not cured during any applicable cure period), the Subscribers
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 equity
linked 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 and, (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, and (iv) as a result of the exercise of
Warrants or conversion of Notes which are granted or issued pursuant to this
Agreement (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
some or all of 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 their purchase of Notes in the Offering. A
Subscriber may elect to purchase less than the maximum amount purchasable by
such Subscriber in which event other Subscribers who have fully exercise their
rights pursuant to this Section 12(a) may elect during the following additional
seven (7) days to purchase in proportion to their initial Note purchase
hereunder the amounts not purchased by the Subscribers who did not purchase the
maximum amount otherwise available to them. 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 the Notes or Warrants are outstanding, 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,
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 such Subscriber (of only the Common Stock
or Warrant Shares still owned by such Subscriber) is equal to such other lower
price per share and the Conversion Price and Warrant exercise price shall
automatically be reduced to such other lower price. The average Purchase Price
of the Shares and average

                                       24
<PAGE>

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 of the Notes and
separately for Warrant Shares. The delivery to such 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. 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 such Subscriber set forth in
this Section 12 are in addition to any other rights such Subscriber has pursuant
to this Agreement, the Note, any Transaction Document, and any other agreement
referred to or entered into in connection herewith. The Subscriber is also given
the right to elect to substitute any term or terms of any other offering in
connection with which such Subscriber has rights as described in Section 12(a),
for any term or terms of the Offering in connection with Securities owned by
Subscriber as of the date the notice described in Section 12(a) is required to
be given to Subscriber.

             (c) Maximum Exercise of Rights. In the event the exercise of the
                 --------------------------
rights described in Sections 12(a) or 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.

between the parties hereto with respect to the subject matter hereof and may be
amended only by a writing executed by both parties. Neither the Company nor the

             (d) Law Governing this Agreement. This Agreement shall be governed
                 ----------------------------
by and construed in accordance with the laws of the State of New Jersey 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 Jersey or in the
federal courts located in the State of New Jersey. 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

                                       26
<PAGE>

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 signator hereto in his or her 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) 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 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 a 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.

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

             (h) Consent. As used in the Agreement, "consent of the Subscribers"
                 -------
or similar language means the consent of holders of not less than 70% of the
total of the Shares issued and issuable upon conversion of outstanding Notes
owned by Subscribers on the date consent is requested.

                                       27
<PAGE>

             (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 Subscribers and their permitted successors and assigns.

             (j) Maximum Payments. 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 rate permitted by applicable law. In the event that the
rate of interest or dividends required to be paid or other charges hereunder
exceed the maximum permitted by such law, any payments in excess of such maximum
rate shall be credited against amounts owed by the Company to a Subscriber and
thus refunded to the Company.

             (m) Captions: Certain Definitions. The captions of the various
                 -----------------------------
sections and paragraphs of this Agreement have been inserted only for the
purposes of convenience; such captions are not a part of this Agreement and
shall not be deemed in any manner to modify, explain, enlarge or restrict any of
the provisions of this Agreement. As used in this Agreement the term "person"
                                                                      ------
shall mean and include an individual, a partnership, a joint venture, a
corporation, a limited liability company, a trust, an unincorporated
organization and a government or any department or agency thereof.

             (n) Severability. In the event that any term or provision of this
                 ------------
Agreement shall be finally determined to be superseded, invalid, illegal or
otherwise unenforceable pursuant to applicable law by an authority having
jurisdiction and venue, that determination shall not impair or otherwise affect
the validity, legality or enforceability: (i) by or before that authority of the
remaining terms and provisions of this Agreement, which shall be enforced as if
the unenforceable term or provision were deleted, or (ii) by or before any other
authority of any of the terms and provisions of this Agreement.

             (o) Successor Laws. References in the Transaction Documents to
                 --------------
laws, rules, regulations and forms shall also include successors to and
functionally equivalent replacements of such laws, rules, regulations and forms.
A successor rule to 144(b)(1)(i) shall include any rule that would be available
to a non-Affiliate of the Company for the sale of Common Stock not subject to
volume restrictions and after a six month holding period.

otherwise) which the holder of the Warrant at any time shall be entitled to
receive, or shall have received, on the exercise of the Warrant, in lieu of or

                                       2
<PAGE>

                  (b) If the Company's Common Stock is not traded on an exchange
or on the NASDAQ Global Market, NASDAQ Global Select Market, the NASDAQ Capital
Market or the American Stock Exchange, Inc., but is traded in the
over-the-counter market, then the average of the closing bid and ask prices
reported for the last business day immediately preceding the Determination Date;

                  (c) Except as provided in clause (d) below and Section 3.1, if
the Company's Common Stock is not publicly traded, then as the Holder and the
Company agree, or in the absence of such an agreement, by arbitration in
accordance with the rules then standing of the American Arbitration Association,
before a single arbitrator to be chosen from a panel of persons qualified by
education and training to pass on the matter to be decided; or

                  (d) If the Determination Date is the date of a liquidation,
dissolution or winding up, or any event deemed to be a liquidation, dissolution
or winding up pursuant to the Company's charter, then all amounts to be payable
per share to holders of the Common Stock pursuant to the charter in the event of
such liquidation, dissolution or winding up, plus all other amounts to be
payable per share in respect of the Common Stock in liquidation under the
charter, assuming for the purposes of this clause (d) that all of the shares of
Common Stock then issuable upon exercise of all of the Warrants are outstanding
at the Determination Date.

             1.5. Company Acknowledgment. The Company will, at the time of the
                  ----------------------
exercise of the Warrant, upon the request of the Holder hereof acknowledge in
writing its continuing obligation to afford to such Holder any rights to which
such Holder shall continue to be entitled after such exercise in accordance with
the provisions of this Warrant. If the Holder shall fail to make any such
request, such failure shall not affect the continuing obligation of the Company
to afford to such Holder any such rights.

             1.6. Trustee for Warrant Holders. In the event that a bank or trust
                  ---------------------------
company shall have been appointed as trustee for the Holder of the Warrants
pursuant to Subsection 3.2, such bank or trust company shall, to the extent
permitted by applicable law, have all the powers and duties of a warrant agent
(as hereinafter described) and shall accept, in its own name for the account of
the Company or such successor person as may be entitled thereto, all amounts
otherwise payable to the Company or such successor, as the case may be, on
exercise of this Warrant pursuant to this Section 1.

             1.7 Delivery of Stock Certificates, etc. on Exercise. The Company
                 ------------------------------------------------
agrees that the shares of Common Stock purchased upon exercise of this Warrant
shall be deemed to be issued to the Holder hereof as the record owner of such
shares as of the close of business on the date on which this Warrant shall have
been surrendered and payment made for such shares as aforesaid. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within three (3) business days thereafter ("Warrant Share Delivery Date"),
the Company at its expense (including the payment by it of any applicable issue
taxes) will cause to be issued in the name of and delivered to the Holder
hereof, or as such Holder (upon payment by such Holder of any applicable
transfer taxes) may direct in compliance with applicable securities laws, a
certificate or certificates for the number of duly and validly issued, fully
paid and nonassessable shares of Common Stock (or Other Securities) to which
such Holder shall be entitled on such exercise, plus, in lieu of any fractional
share to which such Holder would otherwise be entitled, cash equal to such
fraction multiplied by the then Fair Market Value of one full share of

                                       3
<PAGE>

Common Stock, together with any other stock or other securities and property
(including cash, where applicable) to which such Holder is entitled upon such
exercise pursuant to Section 1 or otherwise. The Company understands that a
delay in the delivery of the Warrant Shares after the Warrant Share Delivery
Date could result in economic loss to the Holder. As compensation to the Holder
for such loss, the Company agrees to pay (as liquidated damages and not as a
penalty) to the Holder for late issuance of Warrant Shares upon exercise of this
Warrant the amount of $100 per business day after the Warrant Share Delivery
Date for each $10,000 of Exercise Price of Warrant Shares for which this Warrant
is exercised 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
Holder, in the event that the Company fails for any reason to effect delivery of
the Warrant Shares by the Warrant Share Delivery Date, the Holder may revoke all
or part of the relevant Warrant exercise by delivery of a notice to such effect
to the Company whereupon the Company and the Holder shall each be restored to
their respective positions immediately prior to the exercise of the relevant
portion of this Warrant, except that the liquidated damages described above
shall be payable through the date notice of revocation or rescission is given to
the Company.

             1.8 Buy-In. In addition to any other rights available to the
                 ------
Holder, if the Company fails to deliver to a Holder the Warrant Shares as
required pursuant to this Warrant, within seven (7) business days after the
Warrant Share Delivery Date and the Holder or a broker on the Holder's behalf,
purchases (in an open market transaction or otherwise) shares of common stock to
deliver in satisfaction of a sale by such Holder of the Warrant Shares which the
Holder was entitled to receive from the Company (a "Buy-In"), then the Company
shall pay in cash to the Holder (in addition to any remedies available to or
elected by the Holder) the amount by which (A) the Holder's total purchase price
(including brokerage commissions, if any) for the shares of common stock so
purchased exceeds (B) the aggregate Exercise Price of the Warrant Shares
required to have been delivered 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 Holder purchases shares of Common Stock having a total
purchase price of $11,000 to cover a Buy-In with respect to $10,000 of Exercise
Price of Warrant Shares to have been received upon exercise of this Warrant, the
Company shall be required to pay the Holder $1,000, plus interest. The Holder
shall provide the Company written notice indicating the amounts payable to the
Holder in respect of the Buy-In.

         2.  Cashless Exercise.
             -----------------

             (a) If a registration statement (as described in Section 11 of the
Subscription Agreement) (the "Registration Statement") is effective and the
Holder may sell its shares of Common Stock upon exercise hereof pursuant to the
Registration Statement, this Warrant may be exercisable in whole or in part for
cash only as set forth in Section 1 above. If the Registration Statement is not
available, then commencing one year after the Issue Date, payment upon exercise
may be made at the option of the Holder either in (i) cash, wire transfer or by
certified or official bank check payable to the order of the Company equal to
the applicable aggregate Exercise Price, (ii) by delivery of Common Stock
issuable upon exercise of the Warrants in accordance with Section (b) below or
(iii) by a combination of any of the foregoing

                                       4
<PAGE>

methods, for the number of Common Stock specified in such form (as such exercise
number shall be adjusted to reflect any adjustment in the total number of shares
of Common Stock issuable to the holder per the terms of this Warrant) and the
holder shall thereupon be entitled to receive the number of duly authorized,
validly issued, fully-paid and non-assessable shares of Common Stock (or Other
Securities) determined as provided herein.

             (b) Subject to the provisions herein to the contrary, if the Fair
Market Value of one share of Common Stock is greater than the Exercise Price (at
the date of calculation as set forth below), in lieu of exercising this Warrant
for cash, the holder may elect to receive shares equal to the value (as
determined below) of this Warrant (or the portion thereof being cancelled) by
surrender of this Warrant at the principal office of the Company together with
the properly endorsed Subscription Form in which event the Company shall issue
to the holder a number of shares of Common Stock computed using the following
formula:

                           X=Y (A-B)
                             -------
                               A

                  Where    X=       the number of shares of Common Stock to be
                                    issued to the holder

                           Y=       the number of shares of Common Stock
                                    purchasable under the Warrant or, if only a
                                    portion of the Warrant is being exercised,
                                    the portion of the Warrant being exercised
                                    (at the date of such calculation)

                           A=       the average Fair Market Value of a share of
                                    Common stock for the five (5) trading days
                                    immediately prior to (but not including) the
                                    Exercise Date

                           B=       Exercise Price (as adjusted to the date of
                                    such calculation)

             For purposes of Rule 144 promulgated under the 1933 Act, it is
intended, understood and acknowledged that the Warrant Shares issued in a
cashless exercise transaction shall be deemed to have been acquired by the
Holder, and the holding period for the Warrant Shares shall be deemed to have
commenced, on the date this Warrant was originally issued pursuant to the
Subscription Agreement.

         3.  Adjustment for Reorganization, Consolidation, Merger, etc.
             ---------------------------------------------------------

             3.1. Reorganization, Consolidation, Merger, etc. In case at any
                  ------------------------------------------
time or from time to time, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company, then, in each such
case, as a condition to the consummation of such a transaction, proper and
adequate provision shall be made by the Company whereby the Holder of this
Warrant, on the exercise hereof as provided in Section 1, at any time after the
consummation of such reorganization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise prior to such
consummation or such effective date, the stock and other securities and property
(including

                                       5
<PAGE>

cash) to which such Holder would have been entitled upon such consummation or in
connection with such dissolution, as the case may be, if such Holder had so
exercised this Warrant, immediately prior thereto, all subject to further
adjustment thereafter as provided in Section 4.

             3.2. Dissolution. In the event of any dissolution of the Company
                  -----------
following the transfer of all or substantially all of its properties or assets,
the Company, prior to such dissolution, shall at its expense deliver or cause to
be delivered the stock and other securities and property (including cash, where
applicable) receivable by the Holder of the Warrants after the effective date of
such dissolution pursuant to this Section 3 to a bank or trust company (a
"Trustee") having its principal office in New York, New York, as trustee for the
Holder of the Warrants.

             3.3. Continuation of Terms. Upon any reorganization, consolidation,
                  ---------------------
merger or transfer (and any dissolution following any transfer) referred to in
this Section 3, this Warrant shall continue in full force and effect and the
terms hereof shall be applicable to the Other Securities and property receivable
on the exercise of this Warrant after the consummation of such reorganization,
consolidation or merger or the effective date of dissolution following any such
transfer, as the case may be, and shall be binding upon the issuer of any Other
Securities, including, in the case of any such transfer, the person acquiring
all or substantially all of the properties or assets of the Company, whether or
not such person shall have expressly assumed the terms of this Warrant as
provided in Section 4. In the event this Warrant does not continue in full force
and effect after the consummation of the transaction described in this Section
3, then only in such event will the Company's securities and property (including
cash, where applicable) receivable by the Holder of the Warrants be delivered to
the Trustee as contemplated by Section 3.2.

             3.4 Share Issuance. Until the Expiration Date, if the Company shall
                 --------------
issue any Common Stock except for the Excepted Issuances (as defined in the
Subscription Agreement), prior to the complete exercise of this Warrant for a
consideration less than the Exercise Price that would be in effect at the time
of such issue, then, and thereafter successively upon each such issue, the
Exercise Price shall be reduced to such other lower price for then outstanding
Warrants. For purposes of this adjustment, the issuance of any security or debt
instrument of the Company carrying the right to convert such security or debt
instrument into Common Stock or of any warrant, right or option to purchase
Common Stock shall result in an adjustment to the Exercise Price upon the
issuance of the above-described security, debt instrument, warrant, right, or
option if such issuance is at a price lower than the Exercise Price in effect
upon such issuance 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 Exercise Price in effect upon such
issuance. The reduction of the Exercise Price described in this Section 3.4 is
subject to the provisions of, and in addition to the other rights of the Holder
described in, the Subscription Agreement.

         4.  Extraordinary Events Regarding Common Stock. In the event that the
             -------------------------------------------
Company shall (a) issue additional shares of the Common Stock as a dividend or
other distribution on outstanding Common Stock, (b) subdivide its outstanding
shares of Common Stock, or (c) combine its outstanding shares of the Common
Stock into a smaller number of shares of the Common Stock, then, in each such
event, the Exercise Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Exercise Price by a fraction, the

                                       6
<PAGE>

numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event, and the
product so obtained shall thereafter be the Exercise Price then in effect. The
Exercise Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described herein in this Section 4.
The number of shares of Common Stock that the Holder of this Warrant shall
thereafter, on the exercise hereof, be entitled to receive shall be adjusted to
a number determined by multiplying the number of shares of Common Stock that
would otherwise (but for the provisions of this Section 4 be issuable on such
exercise by a fraction of which (a) the numerator is the Exercise Price that
would otherwise (but for the provisions of this Section 4 be in effect, and (b)
the denominator is the Exercise Price in effect on the date of such exercise.

         5.  Certificate as to Adjustments. In each case of any adjustment or
             -----------------------------
readjustment in the shares of Common Stock (or Other Securities) issuable on the
exercise of this Warrant, the Company at its expense will promptly cause its
Chief Financial Officer or other appropriate designee to compute such adjustment
or readjustment in accordance with the terms of this Warrant and prepare a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based, including a
statement of (a) the consideration received or receivable by the Company for any
additional shares of Common Stock (or Other Securities) issued or sold or deemed
to have been issued or sold, (b) the number of shares of Common Stock (or Other
Securities) outstanding or deemed to be outstanding, and (c) the Exercise Price
and the number of shares of Common Stock to be received upon exercise of this
Warrant, in effect immediately prior to such adjustment or readjustment and as
adjusted or readjusted as provided in this Warrant. The Company will forthwith
mail a copy of each such certificate to the Holder of this Warrant and any
Warrant Agent of the Company (appointed pursuant to Section 11 hereof).

         6.  Reservation of Stock, etc. Issuable on Exercise of Warrant;
             -----------------------------------------------------------
Financial Statements. The Company will at all times reserve and keep available,
--------------------
solely for issuance and delivery on the exercise of the Warrants, all shares of
Common Stock (or Other Securities) from time to time issuable on the exercise of
the Warrant. This Warrant entitles the Holder hereof to receive copies of all
financial and other information distributed or required to be distributed to the
holders of the Company's Common Stock.

         7.  Assignment; Exchange of Warrant. Subject to compliance with
             -------------------------------
applicable securities laws, this Warrant, and the rights evidenced hereby, may
be transferred by any registered holder hereof (a "Transferor"). On the
surrender for exchange of this Warrant, with the Transferor's endorsement in the
form of Exhibit B attached hereto (the "Transferor Endorsement Form") and
together with an opinion of counsel reasonably satisfactory to the Company that
the transfer of this Warrant will be in compliance with applicable securities
laws, the Company will issue and deliver to or on the order of the Transferor
thereof a new Warrant or Warrants of like tenor, in the name of the Transferor
and/or the transferee(s) specified in such Transferor Endorsement Form (each a
"Transferee"), calling in the aggregate on the face or faces thereof for the
number of shares of Common Stock called for on the face of the Warrant so
surrendered by the Transferor.

         8.  Replacement of Warrant. On receipt of evidence reasonably
             ----------------------
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of any such

                                       7
<PAGE>

loss, theft or destruction of this Warrant, on delivery of an indemnity
agreement or security reasonably satisfactory in form and amount to the Company
or, in the case of any such mutilation, on surrender and cancellation of this
Warrant, the Company at its expense, twice only, will execute and deliver, in
lieu thereof, a new Warrant of like tenor.

         9.  Registration Rights. The Holder of this Warrant has been granted
             -------------------
certain registration rights by the Company. These registration rights are set
forth in the Subscription Agreement. The terms of the Subscription Agreement are
incorporated herein by this reference.

         10. Maximum Exercise. The Holder shall not be entitled to exercise this
             ----------------
Warrant on an exercise date, in connection with that number of shares of Common
Stock which would be in excess of the sum of (a) the number of shares of Common
Stock beneficially owned by the Holder and its affiliates on an exercise date,
and (b) the number of shares of Common Stock issuable upon the exercise of this
Warrant with respect to which the determination of this limitation is being made
on an exercise 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
on such date. For the purposes of 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 exercises which
would result in the issuance of more than 4.99%. The restriction described in
this paragraph may be waived, in whole or in part, upon sixty-one (61) days
prior notice from the Holder to the Company to increase such percentage to up to
9.99%, but not in excess of 9.99%. The Holder may decide whether to convert a
Note or exercise this Warrant to achieve an actual 4.99% or up to 9.99%
ownership position as described above, but not in excess of 9.99%.

         11. Warrant Agent. The Company may, by written notice to the Holder of
             -------------
the Warrant, appoint an agent (a "Warrant Agent") for the purpose of issuing
Common Stock (or Other Securities) on the exercise of this Warrant pursuant to
Section 1, exchanging this Warrant pursuant to Section 7, and replacing this
Warrant pursuant to Section 8, or any of the foregoing, and thereafter any such
issuance, exchange or replacement, as the case may be, shall be made at such
office by such Warrant Agent.

         12. Transfer on the Company's Books. Until this Warrant is transferred
             -------------------------------
on the books of the Company, the Company may treat the registered Holder hereof
as the absolute owner hereof for all purposes, notwithstanding any notice to the
contrary.

         13. Notices. All notices, demands, requests, consents, approvals, and
