                                     ARTICLE II

                                 CONVERSION RIGHTS

          The Holder shall have the right to convert the principal
amount and interest due under this Note into Shares of the Borrower's
Common Stock as set forth below.

          2.1. Conversion into the Borrower's Common Stock.

          (a) The Holder shall have the right from and after the
issuance of this Note and then at any time until this Note is fully paid,
to convert any outstanding and unpaid principal portion of this Note,
and/or at the Holder's election with the Company's consent, the interest
accrued on the Note, (the date of giving of such notice of conversion
being a "Conversion Date") into fully paid and nonassessable shares of
common stock of Borrower as such stock exists on the date of issuance of
this Note, or any shares of capital stock of Borrower into which such
stock shall hereafter be changed or reclassified (the "Common Stock") at
the conversion price as defined in Section 2.1(b) hereof (the "Conversion
Price"), determined as provided herein.  Upon delivery to the Company of
a Notice of Conversion as described in Section 9 of the subscription
agreement entered into between the Company and Holder relating to this
Note (the "Subscription Agreement") of the Holder's written request for
conversion, Borrower shall issue and deliver to the Holder within three
business days from the Conversion Date that number of shares of Common
Stock for the portion of the Note converted in accordance with the
foregoing.  At the election of the Holder, the Company will deliver
accrued but unpaid interest on the Note through the Conversion Date
directly to the Holder on or before the Delivery Date (as defined in the
Subscription Agreement).  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 and interest,
if any, by the Conversion Price.

          (b) Subject to adjustment as provided in Section 2.1(c)
hereof, the Conversion Price per share shall be the lower of (i) eighty-
five percent (85%) of the average of the three lowest closing prices for
the Common Stock on the NASD OTC Bulletin Board, NASDAQ SmallCap Market,
NASDAQ National Market System, American Stock Exchange, or New York Stock
Exchange (whichever of the foregoing is at the time the principal trading
exchange or market for the Common Stock, the "Principal Market"), or if
not then trading on a Principal Market, such other principal market or
exchange where the Common Stock is listed or traded for the thirty (30)
trading days prior to but not including the  Closing Date (as defined in
the Subscription Agreement) in connection with which this Note is issued
("Maximum Base Price"); or (ii) eighty-five percent (85%) percent of the
average of the three lowest closing prices for the Common Stock on the
Principal Market, or on any securities exchange or other securities
market on which the Common Stock is then being listed or traded, for the
thirty (30) trading days prior to but not including the Conversion Date.

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

-2-
<PAGE>

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

          B. Reclassification, etc.  If the Borrower at any time
shall, by reclassification or otherwise, change the Common Stock into the
same or a different number of securities of any class or classes, this
Note, as to the unpaid principal portion thereof and accrued interest
thereon, shall thereafter be deemed to evidence the right to purchase an
adjusted number of such securities and kind of securities as would have
been issuable as the result of such change with respect to the Common
Stock immediately prior to such reclassification or other change.

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

          D. Share Issuance.  Subject to the provisions of this
Section, if the Borrower at any time shall issue any shares of Common
Stock prior to the conversion of the entire principal amount of the Note
(otherwise than as: (i) provided in Sections 2.1(c)A, 2.1(c)B or 2.1(c)C
or this subparagraph D; (ii) pursuant to options, warrants, or other
obligations to issue shares, outstanding on the date hereof as described
in the Reports and Other Written Information, as such terms are defined
in the Subscription Agreement (which agreement is incorporated herein by
this reference); or (iii) Excepted Issuances, as defined in Section 12 of
the Subscription Agreement; ((i), (ii) and (iii) above, are hereinafter
referred to as the "Existing Option Obligations") for a consideration
less than the Conversion Price that would be in effect at the time of
such issue, then, and thereafter successively upon each such issue, the
Conversion Price shall be reduced as follows:  (i) the number of shares
of Common Stock outstanding immediately prior to such issue shall be
multiplied by the Conversion Price in effect at the time of such issue
and the product shall be added to the aggregate consideration, if any,
received by the Borrower upon such issue of additional shares of Common
Stock; and (ii) the sum so obtained shall be divided by the number of
shares of Common Stock outstanding immediately after such issue.  The
resulting quotient shall be the adjusted conversion price.  Except for
the Existing Option Obligations, for purposes of this adjustment, the
issuance of any security of the Borrower 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 shares of Common Stock upon
exercise of such conversion or purchase rights.

-3-
<PAGE>

          (d) During the period the conversion right exists, Borrower
will reserve from its authorized and unissued Common Stock a sufficient
number of shares to provide for the issuance of Common Stock upon the
full conversion of this Note.  Borrower represents that upon issuance,
such shares will be duly and validly issued, fully paid and non-
assessable.  Borrower agrees that its issuance of this Note shall
constitute full authority to its officers, agents, and transfer agents
who are charged with the duty of executing and issuing stock certificates
to execute and issue the necessary certificates for shares of Common
Stock upon the conversion of this Note.

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

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

           3.1 Failure to Pay Principal or Interest.  The Borrower fails

day period described in Section 1.1 hereof.

           3.2 Breach of Covenant.  The Borrower breaches any material
covenant or other term or condition of this Note in any material respect
and such breach, if subject to cure, continues for a period of seven (7)
days after written notice to the Borrower from the Holder.

           3.3 Breach of Representations and Warranties.  Any material
representation or warranty of the Borrower made herein, in the
Subscription Agreement entered into by the Holder and Borrower in
connection with this Note, or in any agreement, statement or certificate
given in writing pursuant hereto or in connection therewith shall be
false or misleading in any material respect.

are bound or affected, which default or violation would have a material
adverse effect on the Company, (ii) in default with respect to any order
of any court, arbitrator or governmental body or subject to or party to

action, suit or proceeding under any statute or other law respecting

matters, or (iii) to its knowledge in violation of any statute, rule or
regulation of any governmental authority which violation would have a
material adverse effect on the Company.

knowledge after due inquiry with regulatory authorities, neither the
Company, nor any of its affiliates, nor any person acting on its or their
behalf, has directly or indirectly made any offers or sales of any

aggregate, which are not disclosed in the Reports and Other Written

no event or circumstance has occurred or exists with respect to the
Company or its businesses, properties, prospects, operations or financial

annexed hereto as Exhibit C. The Company will provide, at the Company's
expense, such other legal opinions in the future as are reasonably
necessary for the conversion of the Note and exercise of the Warrants.

4. Reissuance of Securities.  The Company agrees to reissue
certificates representing the Securities without the legends set forth in
Sections 1(e) and 1(f) above at such time as (a) the holder thereof is
permitted to and disposes of such Securities pursuant to Rule 144(d)
and/or Rule 144(k) under the 1933 Act in the opinion of counsel
reasonably satisfactory to the Company, or (b) upon resale subject to an
effective registration statement after the Securities are registered
under the 1933 Act.  The Company agrees to cooperate with the Subscriber
in connection with all resales pursuant to Rule 144(d) and Rule 144(k)
and provide legal opinions necessary to allow such resales provided the
Company and its counsel receive all reasonably requested written
representations from the Subscriber and selling broker, if any.  If the

Company shall pay to each Subscriber or assignee holding shares subject
to a Legend Removal Failure an amount equal to one percent (1%) of the
Purchase Price of the shares subject to a Legend Removal Failure per day
that such failure continues.  If during any twelve (12) month period, the
Company fails to remove any legend as required by this Section 4 for an
aggregate of thirty (30) days, each Subscriber or assignee holding
Securities subject to a Legend Removal Failure may, at its option,
require the Company to purchase all or any portion of the Securities
subject to a Legend Removal Failure held by such Subscriber or assignee
at a price per share equal to 120% of the applicable Purchase Price.

5. Redemption.  The Company may not redeem the Securities
without the consent of the holder of the Securities except as otherwise
described herein.

other hand, agree to indemnify the other against and hold the other
harmless from any and all liabilities to any other persons claiming

obligations outstanding on or after the Closing Date.  A deviation from

<PAGE>

(b)  Subscriber agrees to indemnify, hold harmless,
reimburse and defend the Company and each of the Company's officers and
directors at all times 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 misrepresentation by
Subscriber in this Agreement or in any Exhibits or Schedules attached
hereto, or other agreement delivered pursuant hereto; or (ii) after any
applicable notice and/or cure periods, any breach or default in
performance by Subscriber of any covenant or undertaking to be performed
by Subscriber hereunder, or any other agreement entered into by the
Company and Subscribers relating hereto.

 (c)  The procedures set forth in Section 10.6 shall apply to
the indemnifications set forth in Sections 8(a) and 8(b) above.

9.1. Conversion of Note.

   (a)  Upon the conversion of the Note or part thereof, the Company
shall, at its own cost and expense, take all necessary action (including
the issuance of an opinion of counsel) to assure that the Company's
transfer agent shall issue stock certificates in the name of Subscriber
(or its nominee) or such other persons as designated by Subscriber and in
such denominations to be specified at conversion representing the number
of shares of common stock issuable upon such conversion.  The Company
warrants that no instructions other than these instructions have been or
will be given to the transfer agent of the Company's Common Stock and
that the Shares will be unlegended, free-trading, and freely
transferable, and will not contain a legend restricting the resale or
transferability of the Company Shares provided the Shares are being sold
pursuant to an effective registration statement covering the Shares to be
sold or are otherwise exempt from registration when sold.

(b)  Subscriber will give notice of its decision to
exercise its right to convert the Note or part thereof by telecopying an
executed and completed Notice of Conversion (as defined in the Note) to
the Company via confirmed telecopier transmission.  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 or cause the transfer
agent to transmit the Company's Common Stock certificates representing
the Shares issuable upon conversion of the Note to the Subscriber via
express courier for receipt by such Subscriber within three (3) business
days after receipt by the Company of the Notice of Conversion (the
"Delivery Date").  A Note representing the balance of the Note not so
converted will be provided to the Subscriber, if requested by Subscriber.
 To the extent that a Subscriber elects not to surrender a Note for
reissuance upon partial payment or conversion, the Subscriber hereby
indemnifies the Company against any and all loss or damage attributable
to a third-party claim in an amount in excess of the actual amount then
due under the Note.

(c)  The Company understands that a delay in the delivery
of the Shares in the form required pursuant to Section 9 hereof, or the
Mandatory Redemption Amount described in Section 9.2 hereof, beyond the
Delivery Date or Mandatory Redemption Payment Date (as hereinafter
defined) could result in economic loss to the Subscriber.  As
compensation to the Subscriber for such loss, the Company agrees to pay
late payments to the Subscriber for late issuance of Shares in the form
required pursuant to Section 9 hereof upon Conversion of the Note or late
payment of the Mandatory Redemption Amount, in the amount of $100 per
business day after the Delivery Date or Mandatory Redemption Payment
Date, as the case may be, for each $10,000 of Note principal amount being
converted or redeemed.  The Company shall pay any payments incurred under
this Section in immediately available funds upon demand.  Furthermore, in
addition to any other remedies which may be available to the Subscriber,
in the event that the Company fails for any reason to effect delivery of
the Shares by the Delivery Date or make payment by the Mandatory
Redemption Payment Date, the Subscriber 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 the Subscriber shall each be
restored to their respective positions immediately prior to the delivery
of such notice, except that late payment charges described above shall be
payable through the date notice of revocation or rescission is given to
the Company.

-9-
<PAGE>

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

9.2. Mandatory Redemption.  In the event the Company is
prohibited from issuing Shares, or fails to timely deliver Shares on a
Delivery Date, or upon the occurrence of an Event of Default (as defined
in the Note) or for any reason other than pursuant to the limitations set
forth in Section 9.3 hereof, then at the Subscriber's election, the
Company must pay to the Subscriber ten (10) business days after request
by the Subscriber or on the Delivery Date (if requested by the
Subscriber) a sum of money determined by multiplying up to the
outstanding principal amount of the Note designated by the Subscriber by
130%, together with accrued but unpaid interest thereon ("Mandatory
Redemption Payment").  The Mandatory Redemption Payment must be received
by the Subscriber on the same date as the Company Shares otherwise
deliverable or within ten (10) business days after request, whichever is
sooner ("Mandatory Redemption Payment Date"). Upon receipt of the
Mandatory Redemption Payment, the corresponding Note principal and
interest will be deemed paid and no longer outstanding.

9.3. Maximum Conversion.  The Subscriber shall not be entitled
to convert on a Conversion Date that amount of the Note in connection
with that number of shares of Common Stock which would be in excess of
the sum of (i) the number of shares of Common Stock beneficially owned by
the Subscriber and its affiliates on a Conversion Date, and (ii) the
number of shares of Common Stock issuable upon the conversion of the Note
with respect to which the determination of this provision is being made
on a Conversion Date, which would result in beneficial ownership by the
Subscriber and its affiliates of more than 4.99% of the outstanding
shares of Common Stock of the Company on such Conversion Date.  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 Subscriber shall not be
limited to aggregate conversions of only 4.99%.  The Subscriber may void
the conversion limitation described in this Section 9.3 upon 75 days
prior written notice to the Company.  The Subscriber may allocate which
of the equity of the Company deemed beneficially owned by the Subscriber
shall be included in the 4.99% amount described above and which shall be
allocated to the excess above 4.99%.

9.4. Injunction - Posting of Bond.  In the event a Subscriber
shall elect to convert a Note or part thereof, the Company may not refuse
conversion 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 said
Note shall have been sought and obtained and the Company posts a surety
bond for the benefit of such Subscriber in the amount of 130% of the
amount of the Note, which is 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.

-10-
<PAGE>

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

9.6 Adjustments.   The Conversion Price and amount of Shares
issuable upon conversion of the Notes and Put Notes shall be adjusted
consistent with customary anti-dilution adjustments.

  9.7. Optional Redemption.  The Company will have the option of
redeeming any outstanding Notes ("Optional Redemption") by paying to the
Subscriber a sum of money as follows:

   from the Closing Date through 30 days after the Closing Date - 120%
   from 31 days through 90 days after the Closing Date - 135%
   from 91 days through 180 days after the Closing Date - 150%
   after 180 days following the Closing Date - 200%

of the principal amount of the Note together with accrued but unpaid
interest thereon and any and all other sums due, accrued or payable to
the Subscriber arising under this Subscription Agreement, Note or any
other document delivered herewith ("Redemption Amount") outstanding on
the day notice of redemption ("Notice of Redemption) is given to a
Subscriber ("Redemption Date").  A Notice of Redemption may not be given
in connection with any portion of Note for which notice of conversion has
been given by the Subscriber at any time before receipt of a Notice of
Redemption.  The Subscriber may elect within five (5) business days after
receipt of a Notice of Redemption to give the Company Notice of
Conversion in connection with some or all of the Note principal and
interest which was the subject of the Notice of Redemption.  A Notice of
Redemption must be accompanied by a certificate signed by the chief
executive officer or chief financial officer of the Company stating that
the Company has on deposit and segregated ready funds equal to the
Redemption Amount.  The Redemption Amount must be paid in good funds to
the Subscriber no later than the seventh (7th)  business day after the
Redemption Date ("Optional Redemption Payment Date").  In the event the
Company fails to pay the Redemption Amount by the Optional Redemption
Payment Date, then the Redemption Notice will be null and void and the
Company will thereafter have no further right to effect an Optional
Redemption, and at the Subscription's election, the Redemption Amount
will be deemed a Mandatory Redemption Payment and the Optional Redemption
Payment Date will be deemed a Mandatory Redemption Payment Date.  Such
failure will also be deemed an Event of Default under the Note.  Any
Notice of Redemption must be given to all holders of Notes issued in
connection with the Offering, in proportion to their holdings of Note
principal on a Redemption Date.  A Notice of Redemption may be given by
the Company, provided (i) no Event of Default, as described in the Note
shall have occurred or be continuing; and (ii) the Company Shares
issuable upon conversion of the full outstanding Note principal are
included for unrestricted resale in a registration statement effective as
of the Redemption Date.  Note proceeds may not be used to effect an
Optional Redemption.

  10.1. Registration Rights.  The Company hereby grants the following
registration rights to holders of the Securities.

   (i)  On one occasion, for a period commencing 61 days after the
Closing Date, but not later than three years after the Closing Date
("Request Date"), the Company, upon a written request therefor from any
record holder or holders of more than 50% of the aggregate of the
Company's Shares issued and issuable upon Conversion of the Notes (the
Common Stock issued or issuable upon conversion of the Notes or issuable
by virtue of ownership of the Note, being, the "Registrable Securities"),
shall prepare and file with the SEC a registration statement under the
Act covering the Registrable Securities which are the subject of such
request, unless such Registrable Securities are the subject of an
effective registration statement.  In addition, upon the receipt of such
request, the Company shall promptly give written notice to all other
record holders of the Registrable Securities that such registration
statement is to be filed and shall include in such registration statement
Registrable Securities for which it has received written requests within
10 days after the Company gives such written notice.  Such other
requesting record holders shall be deemed to have exercised their demand
registration right under this Section 10.1(i).  As a condition precedent
to the inclusion of Registrable Securities, the holder thereof shall
provide the Company with such information as the Company reasonably
requests.  The obligation of the Company under this Section 10.1(i) shall
be limited to one registration statement.

   (ii)  If the Company at any time proposes to register any of its
securities under the Act for sale to the public, whether for its own
account or for the account of other security holders or both, except with
respect to registration statements on Forms S-4, S-8 or another form not
available for registering the Registrable Securities for sale to the
public, provided the Registrable Securities are not otherwise registered
for resale by the Subscriber or Holder pursuant to an effective
registration statement, each such time it will give at least 30 days'
prior written notice to the record holder of the Registrable Securities
of its intention so to do. Upon the written request of the holder,
received by the Company within 20 days after the giving of any such
notice by the Company, to register any of the Registrable Securities, the
Company will cause such Registrable Securities as to which registration
shall have been so requested to be included with the securities to be
covered by the registration statement proposed to be filed by the
Company, all to the extent required to permit the sale or other
disposition of the Registrable Securities so registered by the holder of
such Registrable Securities (the "Seller"). In the event that any
registration pursuant to this Section 10.1(ii) shall be, in whole or in
part, an underwritten public offering of common stock of the Company, the
number of shares of Registrable Securities to be included in such an
underwriting may be reduced by the managing underwriter if and to the
extent that the Company and the underwriter shall reasonably be of the
opinion that such inclusion would adversely affect the marketing of the
securities to be sold by the Company therein; provided, however, that the
Company shall notify the Seller in writing of any such reduction.
Notwithstanding the foregoing provisions, or Section 10.4 hereof, the
Company may withdraw or delay or suffer a delay of any registration
statement referred to in this Section 10.1(ii) without thereby incurring
any liability to the Seller.

   (iii) If, at the time any written request for registration is received
by the Company pursuant to Section 10.1(i), the Company has determined to
proceed with the actual preparation and filing of a registration
statement under the 1933 Act in connection with the proposed offer and
sale for cash of any of its securities for the Company's own account,
such written request shall be deemed to have been given pursuant to
Section 10.1(ii) rather than Section 10.1(i), and the rights of the
holders of Registrable Securities covered by such written request shall
be governed by Section 10.1(ii).

-12-
<PAGE>

(iv) The Company shall file with the Commission within 30
days after written request by the Subscribers (the "Filing Date"), and
use its reasonable commercial efforts to cause to be declared effective
Form SB-2 registration statement (or such other form that it is eligible
to use) in order to register the Registrable Securities for resale and
distribution under the Act.  The registration statement described in this
paragraph must be declared effective by the Commission within 60 days of
the Filing Date (as defined herein) ("Effective Date").  The Company will
register not less than a number of shares of Common Stock in the
aforedescribed registration statement that is equal to 250% of the
Company Shares issuable at the Conversion Price that would be in effect
on the Closing Date or the date of filing of such registration statement
(employing the Conversion Price which would result in the greater number
of Shares), assuming the conversion of 100% of the Notes.  The
Registrable Securities shall be reserved and set aside exclusively for
the benefit of the Subscriber, and not issued, employed or reserved for
anyone other than the Subscriber.  Such registration statement will be
promptly amended or additional registration statements will be promptly
filed by the Company as necessary to register additional Company Shares
to allow the public resale of all Common Stock included in and issuable
by virtue of the Registrable Securities.  No securities of the Company
other than the Registrable Securities will be included in the
registration statement described in this Section 10.1(iv).

10.2. Registration Procedures. If and whenever the Company is
required by the provisions hereof to effect the registration of any
shares of Registrable Securities under the Act, the Company will, as
expeditiously as possible:

(a)  prepare and file with the Commission a registration
statement with respect to such securities and use its best efforts to
cause such registration statement to become and remain effective for the
period of the distribution contemplated thereby (determined as herein
provided), and promptly provide to the holders of Registrable Securities
("Sellers") copies of all filings and Commission letters of comment;

(b)  prepare and file with the Commission such amendments
and supplements to such registration statement and the prospectus used in
connection therewith as may be necessary to keep such registration
statement effective until the latest of: (i) twelve months after the
latest Maturity Date of a Note; (ii) thirty months after the Closing
Date; or (iii) until such registration statement has been effective for a
period of not less than 270 days, and comply with the provisions of the
Act with respect to the disposition of all of the Registrable Securities
covered by such registration statement in accordance with the Seller's
intended method of disposition set forth in such registration statement
for such period;

(c)  furnish to the Seller, and to each underwriter if
any, such number of copies of the registration statement and the
prospectus included therein (including each preliminary prospectus) as
such persons reasonably may request in order to facilitate the public
sale or their disposition of the securities covered by such registration
statement;

(d)  use its best efforts to register or qualify the
Seller's Registrable Securities covered by such registration statement
under the securities or "blue sky" laws of such jurisdictions as the
Seller and in the case of an underwritten public offering, the managing
underwriter shall reasonably request, provided, however, that the Company
shall not for any such purpose be required to qualify generally to
transact business as a foreign corporation in any jurisdiction where it
is not so qualified or to consent to general service of process in any
such jurisdiction;

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

(f)  immediately notify the Seller and each underwriter
under such registration statement at any time when a prospectus relating
thereto is required to be delivered under the Act, of the happening of
any event of which the Company has knowledge as a result of which the
prospectus contained in such registration statement, as then in effect,
includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the
statements therein not misleading in light of the circumstances then
existing;

-13-
<PAGE>

(g)  make available for inspection by the Seller, any
underwriter participating in any distribution pursuant to such
registration statement, and any attorney, accountant or other agent
retained by the Seller or underwriter, all publicly available, non-
confidential financial and other records, pertinent corporate documents
and properties of the Company, and cause the Company's officers,
directors and employees to supply all publicly available, non-
confidential information reasonably requested by the seller, underwriter,
attorney, accountant or agent in connection with such registration
statement.

10.3. Provision of Documents.

   (a)  At the request of the Seller, provided a demand for registration
has been made pursuant to Section 10.1(i) or a request for registration
has been made pursuant to Section 10.1(ii), the Registrable Securities
will be included in a registration statement filed pursuant to this
Section 10.

   (b)  In connection with each registration hereunder, the Seller will
furnish to the Company in writing such information and representation
letters with respect to itself and the proposed distribution by it as
reasonably shall be necessary in order to assure compliance with federal
and applicable state securities laws.  In connection with each
registration pursuant to Section 10.1(i) or 10.1(ii) covering an
underwritten public offering, the Company and the Seller agree to enter
into a written agreement with the managing underwriter in such form and
containing such provisions as are customary in the securities business
for such an arrangement between such underwriter and companies of the
Company's size and investment stature.

  10.4. Non-Registration Events.  The Company and the Subscriber agree
that the Seller will suffer damages if any registration statement
required under Section 10.1(i) or 10.1(ii) above is not filed within 30
days after written request by the Holder and not declared effective by
the Commission within 90 days after such request (or the Filing Date and
Effective Date, respectively, in reference to the Registration Statement
on Form SB-2 or such other form described in Section 10.1(iv)), and
maintained in the manner and within the time periods contemplated by
Section 10 hereof, and it would not be feasible to ascertain the extent
of such damages with precision.  Accordingly, if (i) the Registration
Statement described in Sections 10.1(i) or 10.1(ii) is not filed within
30 days of such written request, or is not declared effective by the
Commission on or prior to the date that is 90 days after such request, or
(ii) the registration statement on Form SB-2 or such other form described
in Section 10.1(iv) is not filed on or before the Filing Date or not
declared effective on or before the sooner of the Effective Date, or
within five business days of receipt by the Company of a written or oral
communication from the Commission that the registration statement
described in Section 10.1(iv) will not be reviewed, or (iii) any
registration statement described in Sections 10.1(i), 10.1(ii) or
10.1(iv) is filed and declared effective but shall thereafter cease to be
effective (without being succeeded immediately by an additional
registration statement filed and declared effective) for a period of time
which shall exceed 30 days in the aggregate per year but not more than 20
consecutive calendar days (defined as a period of 365 days commencing on
the date the Registration Statement is declared effective) (each such
event referred to in clauses (i), (ii) and (iii) of this Section 10.4 is
referred to herein as a "Non-Registration Event"), then, for so long as
such Non-Registration Event shall continue, the Company shall pay, at the
Subscriber's option, in cash or stock at the applicable Conversion Price,
as Liquidated Damages to each holder of any Registrable Securities an
amount equal to two percent (2%) per month or part thereof during the
pendency of such Non-Registration Event, of the principal of the Notes
issued in connection with the Offering, whether or not converted, then
owned of record by such holder or issuable  as of or subsequent to the
occurrence of such Non-Registration Event.  Payments to be made pursuant
to this Section 10.4 shall be due and payable within five (5) business
days after demand in immediately available funds.  In the event a
Mandatory Redemption Payment is demanded from the Company by the Holder
pursuant to Section 9.2 of this Subscription Agreement, then the
Liquidated Damages described in this Section 10.4 shall no longer accrue
on the portion of the Purchase Price underlying the Mandatory Redemption
Payment, from and after the date the Holder receives the Mandatory
Redemption Payment.  It shall also be deemed a Non-Registration Event if
at any time a Note is outstanding, there is less than 125% of the amount
of Common Shares necessary to allow full conversion of such Note at the
then applicable Conversion Price registered for unrestricted resale in an
effective registration statement.

10.5. Expenses.  All expenses incurred by the Company in
complying with Section 10, including, without limitation, all
registration and filing fees, printing expenses, fees and disbursements
of counsel and independent public accountants for the Company, fees and
expenses (including reasonable counsel fees) incurred in connection with
complying with state securities or "blue sky" laws, fees of the National
Association of Securities Dealers, Inc., transfer taxes, fees of transfer
agents and registrars, and costs of insurance are called "Registration
Expenses". All underwriting discounts and selling commissions applicable
to the sale of Registrable Securities, including any fees and
disbursements of any special counsel to the Seller, are called "Selling
Expenses".  The Seller shall pay the fees of its own additional counsel,
if any.  The Company will pay all Registration Expenses in connection
with the registration statement under Section 10.  All Selling Expenses
in connection with each registration statement under Section 10 shall be
borne by the Seller and may be apportioned among the Sellers in
proportion to the number of shares sold by the Seller relative to the
number of shares sold under such registration statement or as all Sellers
thereunder may agree.

10.6. Indemnification and Contribution.

   (a) In the event of a registration of any Registrable Securities under
the Act pursuant to Section 10, the Company will indemnify and hold
harmless the Seller, each officer of the Seller, each director of the
Seller, each underwriter of such Registrable Securities thereunder and
each other person, if any, who controls such Seller or underwriter within
the meaning of the 1933 Act, against any losses, claims, damages or
liabilities, joint or several, to which the Seller, or such underwriter
or controlling person may become subject under the Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in any
registration statement under which such Registrable Securities was
registered under the Act pursuant to Section 10, any preliminary
prospectus or final prospectus contained therein, or any amendment or
supplement thereof, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and
will reimburse the Seller, each such underwriter and each such
controlling person for any legal or other expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the Company shall
not be liable to the Seller to the extent that any such damages arise out
of or are based upon an untrue statement or omission made in any
preliminary prospectus if (i) the Seller failed to send or deliver a copy
of the final prospectus delivered by the Company to the Seller with or
prior to the delivery of written confirmation of the sale by the Seller
to the person asserting the claim from which such damages arise, (ii) the
final prospectus would have corrected such untrue statement or alleged
untrue statement or such omission or alleged omission, or (iii) to the
extent that any such loss, claim, damage or liability arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission so made in conformity with information furnished by any
such Seller, or any such controlling person in writing specifically for
use in such registration statement or prospectus.

   (b) In the event of a registration of any of the Registrable
Securities under the Act pursuant to Section 10, the Seller will
indemnify and hold harmless the Company, and each person, if any, who
controls the Company within the meaning of the Act, each officer of the
Company who signs the registration statement, each director of the
Company, each underwriter and each person who controls any underwriter
within the meaning of the Act, against all losses, claims, damages or
liabilities, joint or several, to which the Company or such officer,
director, underwriter or controlling person may become subject under the
Act or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in

-15-
<PAGE>

the registration statement under which such Registrable Securities were
registered under the Act pursuant to Section 10, any preliminary
prospectus or final prospectus contained therein, or any amendment or
supplement thereof, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and
will reimburse the Company and each such officer, director, underwriter
and controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such
loss, claim, damage, liability or action, provided, however, that the
Seller will be liable hereunder in any such case if and only to the
extent that any such loss, claim, damage or liability arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in reliance upon and in conformity with information
pertaining to such Seller, as such, furnished in writing to the Company
by such Seller specifically for use in such registration statement or
prospectus, and provided, further, however, that the liability of the
Seller hereunder shall be limited to the gross proceeds received by the
Seller from the sale of Registrable Securities covered by such
registration statement.

   (c) Promptly after receipt by an indemnified party hereunder of notice
of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party
hereunder, notify the indemnifying party in writing thereof, but the
omission so to notify the indemnifying party shall not relieve it from
any liability which it may have to such indemnified party other than
under this Section 10.6(c) and shall only relieve it from any liability
which it may have to such indemnified party under this Section 10.6(c),
except and only if and to the extent the indemnifying party is prejudiced
by such omission. In case any such action shall be brought against any
indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to
participate in and, to the extent it shall wish, to assume and undertake
the defense thereof with counsel satisfactory to such indemnified party,
and, after notice from the indemnifying party to such indemnified party
of its election so to assume and undertake the defense thereof, the
indemnifying party shall not be liable to such indemnified party under
this Section 10.6(c) for any legal expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than
reasonable costs of investigation and of liaison with counsel so
selected, provided, however, that, if the defendants in any such action
include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be
reasonable defenses available to it which are different from or
additional to those available to the indemnifying party or if the
interests of the indemnified party reasonably may be deemed to conflict
with the interests of the indemnifying party, the indemnified parties
shall have the right to select one separate counsel and to assume such
legal defenses and otherwise to participate in the defense of such
action, with the reasonable expenses and fees of such separate counsel
and other expenses related to such participation to be reimbursed by the
indemnifying party as incurred.

   (d) In order to provide for just and equitable contribution in the
event of joint liability under the Act in any case in which either (i)
the Seller, or any controlling person of the Seller, makes a claim for
indemnification pursuant to this Section 10.6 but it is judicially
determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial
of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that this Section 10.6
provides for indemnification in such case, or (ii) contribution under the
Act may be required on the part of the Seller or controlling person of
the Seller in circumstances for which indemnification is provided under
this Section 10.6; then, and in each such case, the Company and the
Seller will contribute to the aggregate losses, claims, damages or
liabilities to which they may be subject (after contribution from others)
in such proportion so that the Seller is responsible only for the portion
represented by the percentage that the public offering price of its
securities offered by the registration statement bears to the public
offering price of all securities offered by such registration statement,
provided, however, that, in any such case, (y) the Seller will not be

-16-
<PAGE>

required to contribute any amount in excess of the public offering price
of all such securities offered by it pursuant to such registration
statement; and (z) no person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 10(f) of the Act) will
be entitled to contribution from any person or entity who was not guilty
of such fraudulent misrepresentation.

 10.7. Underwriter Liability.  Nothing contained in this Agreement
or any document delivered herewith shall require or imply that the
Subscriber is or be an Underwriter as defined in the 1933 Act of 1934
Act, nor a "statutory underwriter."  The Subscriber shall not be
required to take any action or assume any liability or obligation which
would or could impose Underwriter or "statutory underwriter" status or
liability on the Subscriber.
