     1.     Exercise of Warrant.

            1.1.     Number of Shares Issuable upon Exercise.  From and
after the date hereof through and including the Expiration Date, the holder
hereof shall be entitled to receive, upon exercise of this Warrant in whole
in accordance with the terms of subsection 1.2 or upon exercise of this
Warrant in part in accordance with subsection 1.3, shares of Common Stock
of the Company, subject to adjustment pursuant to Section 4.

            1.2.     Full Exercise.  This Warrant may be exercised in full
by the holder hereof by delivery of an original or fax copy of the form of
subscription attached as Exhibit A hereto (the "Subscription Form") duly
executed by such holder and surrender of the original Warrant within seven
days of exercise, to the Company at its principal office or at the office
of its Warrant agent (as provided hereinafter), accompanied by payment, in
cash, wire transfer, or by certified or official bank check payable to the
order of the Company, in the amount obtained by multiplying the number of
shares of Common Stock for which this Warrant is then exercisable by the
Purchase Price (as hereinafter defined) then in effect.

            1.3.     Partial Exercise.  This Warrant may be exercised in
part (but not for a fractional share) by surrender of this Warrant in the
manner and at the place provided in subsection 1.2 except that the amount
payable by the holder on such partial exercise shall be the amount obtained
by multiplying (a) the number of shares of Common Stock designated by the
holder in the Subscription Form by (b) the Purchase Price then in effect.
On any such partial exercise, the Company, at its expense, will forthwith
issue and deliver to or upon the order of the holder hereof a new Warrant
of like tenor, in the name of the holder hereof or as such holder (upon
payment by such holder of any applicable transfer taxes) may request, the
number of shares of Common Stock for which such Warrant may still be
exercised.

            1.4.     Fair Market Value. Fair Market Value of a share of
Common Stock as of a particular date (the "Determination Date") shall mean
the Fair Market Value of a share of the Company's Common Stock. Fair Market
Value of a share of Common Stock as of a Determination Date shall mean:

                     (a)     If the Company's Common Stock is traded on an
exchange or is quoted on the National Association of Securities Dealers,
Inc. Automated Quotation ("NASDAQ") National Market System or the NASDAQ
SmallCap Market, then the closing or last sale price, respectively,
reported for the last business day immediately preceding the Determination
Date.

                     (b)     If the Company's Common Stock is not traded on
an exchange or on the NASDAQ National Market System or the NASDAQ SmallCap
Market but is traded in the over-the-counter market, then the mean of the
closing bid and asked prices reported for the last business day immediately
preceding the Determination Date.

                     (c)     Except as provided in clause (d) below, if the
Company's Common Stock is not publicly traded, then as the Holder and the
Company agree or in the absence of 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.

                     (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 holders of
the Warrants pursuant to Subsection 3.2, such bank or trust company shall
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.

     2.1     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 7 days thereafter, 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, 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.

     2.2.     Cashless Exercise.

              (a)     Payment may be made either in (a) cash or by certified
or official bank check payable to the order of the Company equal to the
applicable aggregate Purchase Price, (ii) by delivery of Warrants, Common
Stock and/or Common Stock receivable upon exercise of the Warrants in
accordance with Section (b) below, or (iii) by a combination of any of the
foregoing methods, for the number of Common Shares 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)     Notwithstanding any provisions herein to the contrary,
if the Fair Market Value of one share of Common Stock is greater than the
Purchase Price (at the date of calculation as set forth below), in lieu of
exercising this Warrant for cash, upon consent of the Company, 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

-3-
<PAGE>

         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 Fair Market Value of one share of the Company's Common Stock
             (at the date of such calculation)

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

     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 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 holders of
the Warrants after the effective date of such dissolution pursuant to this
Section 3 to a bank or trust company having its principal office in New
York, NY, as trustee for the holder or holders 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
shares of stock and 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 such stock or 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 holders of the Warrants be delivered to
the Trustee as contemplated by Section 3.2.

            3.4.     Share Issuance.   Except for the Excepted Issuances as
described in Section 11 of the Subscription Agreement, if the Company at
any time shall issue any shares of Common Stock prior to the complete
exercise of this Warrant for a consideration less than the Purchase Price
that would be in effect at the time of such issue, then, and thereafter
successively upon each such issue, the Purchase Price shall be reduced as

-4-
<PAGE>

follows: (i) the number of shares of Common Stock outstanding immediately
prior to such issue shall be multiplied by the Purchase Price in effect at
the time of such issue and the product shall be added to the aggregate
consideration, if any, received by the Company 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 Purchase
Price.  For purposes of this adjustment, 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 an adjustment to the Purchase Price upon the issuance of
shares of Common Stock upon exercise of such conversion or purchase rights.

     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 Purchase Price shall, simultaneously
with the happening of such event, be adjusted by multiplying the then
Purchase Price by a fraction, the 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 Purchase Price then in effect. The Purchase 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 as provided in Section 1, be entitled to receive
shall be increased 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 Purchase Price that would otherwise (but for the
provisions of this Section 4) be in effect, and (b) the denominator is the
Purchase 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 the Warrants, 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 the
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 Purchase 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 the 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") with
respect to any or all of the Shares. 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
evidence reasonably satisfactory to the Company demonstrating compliance
with applicable Securities Laws, the Company at its expense but with
payment by the Transferor of any applicable transfer taxes) will issue and

-5-
<PAGE>

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 or faces 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 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 will execute and deliver, in lieu thereof, a new Warrant of
like tenor.

     9.     Subscription Agreement.  This Warrant is issued pursuant to a
Subscription Agreement entered into by the Company and Subscribers of the
Company's 8% Convertible Notes at or prior to the issue date of this
Warrant.  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 (i) the
number of shares of Common Stock beneficially owned by the Holder and its
affiliates on an exercise date, and (ii) the number of shares of Common
Stock issuable upon the exercise of this Warrant with respect to which the
determination of this proviso 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 of the Company on
such date.  For the purposes of the proviso 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 exercises which would result in the issuance of
more than 4.99%.  The restriction described in this paragraph may be
revoked upon 75 days prior notice from the Holder to the Company.  The
Holder 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%.

     11.     Warrant Agent.  The Company may, by written notice to the
each holder of the Warrant, appoint an 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 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, etc.  All notices and other communications from the
Company to the holder of this Warrant shall be mailed by first class
registered or certified mail, postage prepaid, at such address as may have
been furnished to the Company in writing by such holder or, until any such
holder furnishes to the Company an address, then to, and at the address of,
the last holder of this Warrant who has so furnished an address to the
Company.

     14.     Miscellaneous. This Warrant and any term hereof may be
changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of such change, waiver,
discharge or termination is sought. This Warrant shall be construed and
enforced in accordance with and governed by the laws of New York.  Any
dispute relating to this Warrant shall be adjudicated in New York State.
The headings in this Warrant are for purposes of reference only, and shall
not limit or otherwise affect any of the terms hereof.  The invalidity or
unenforceability of any provision hereof shall in no way affect the
validity or enforceability of any other provision.

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 security

or any applicable stockholder approval provisions, including, without
limitation, under the rules and regulations of the NASDAQ SmallCap Market,
as applicable, nor will the Company or any of its affiliates or

liabilities or obligations which are material, individually or in the
aggregate, which are not disclosed in the Reports and Other Written
Information, other than those incurred in the ordinary course of the
Company's businesses since December 31, 2000 and which, individually or in
the aggregate, would not reasonably be expected to have a material adverse
effect on the Company's financial condition.

               (s)  No Undisclosed Events or Circumstances.  Since
December 31, 2000, no event or circumstance has occurred or exists with respect

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

Agreement.

             (g)  The Company undertakes to reserve pro rata on behalf of
each holder of a Note or Warrant, from its authorized but unissued Common
Stock, at all times that Notes or Warrants remain outstanding, a number of
Common Shares equal to not less than 200% of the amount of Common Shares
necessary to allow each such holder to be able to convert all such
outstanding Notes, at the then applicable Conversion Price and one Common
Share for each Common Share issuable upon exercise of the Warrants.

             (h)  The Company and Subscriber agree that  until the
Company either obtains shareholder approval of the issuance of the
Securities, or an exemption from NASDAQ's corporate governance rules as
they may apply to the Securities, and an opinion of counsel reasonably
acceptable to Subscriber that NASDAQ's corporate governance rules do not
conflict with nor may result in a delisting of the Company's common stock
from the SmallCap Market ("the Approval") upon the conversion of the Notes,
each Subscriber may not receive upon conversion of the Notes more than the
number of common shares designated on the Signature Page hereto ("Section 7
Shares").  The Company represents that this number of Company Shares
together with the aggregate of such amounts designated for all investors in
the Offering is not greater than 19.9% of the shares of Company's common
stock outstanding on the Closing Date.  The Company covenants to obtain the
Approval required pursuant to the NASDAQ's corporate governance rules to
allow conversion of all the Notes and interest thereon.  The Company
further covenants to file the preliminary proxy statement relating to the
Approval with the Commission on or before thirty days after the Closing
Date ("Proxy Filing Date").  The Company further covenants to obtain the
Approval no later than ninety days after the Closing Date ("Approval
Date").  The Company's failure to (i) file the proxy on or before the Proxy
Filing Date; or (ii) the Company's failure to obtain the Approval on or
before the Approval Date (each being an "Approval Default") shall be deemed
an Event of Default under the Note, but only to the extent the Notes and
interest thereon that may not be converted due to the Company's failure to
obtain such Approval.  Anything to the contrary in this Section 7(h)
notwithstanding, there shall be no limitation on the amount of Notes that
may be converted by the Subscriber and the amount of Company Shares that
may be issued upon conversion of the Notes provided the Subscriber elects a
Conversion Price (as defined in the Note) equal to the closing price of the
Common Stock on the Closing Date.

            8. Covenants of the Company and Subscriber Regarding Idemnification.

             (a)  The Company agrees to indemnify, hold harmless,
reimburse and defend Subscriber, Subscriber'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 Subscriber or any
such person which results, arises out of or is based upon (i) any
misrepresentation by Company or breach of any warranty by Company in this
Agreement or in any Exhibits or Schedules attached hereto, or other
agreement delivered pursuant hereto; or (ii) after any applicable notice
and/or cure periods, any breach or default in performance by the Company of
any covenant or undertaking to be performed by the Company hereunder, or
any other agreement entered into by the Company and Subscribers relating
hereto.

             (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.

-10-
<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").  Notwithstanding
the foregoing, provided the proxy statement described in Section 7(h) is
filed by the Proxy Filing Date and further provided all of the Company's
officers and directors vote Common Shares owned by them in favor of the
Approval, the Mandatory Redemption Payment shall be 100% of the principal
amount of the Note designated by the Subscriber together with accrued but
unpaid interest if the event giving rise to the Mandatory Redemption
Payment is a consequence exclusively of the Company's failure to obtain the
Approval of its shareholders as contemplated by Section 7(h) hereof.  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.

-11-
<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.

<PAGE>

           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 91 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).

-13-
<PAGE>
             (iv) The Company shall file with the Commission within 25
days after the Closing Date (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 90 days of the Closing 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;

-14-
<PAGE>

             (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;

             (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 (2%) percent 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, 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.

<PAGE>

           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 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 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

the "Excepted Issuances"), the Company will not issue any equity,
convertible debt or other securities, prior to the expiration of a period
equal to the later of (x) 270 days during which the registration statement
described in Section 10.1(iv) above has been effective, or (y) 12 months
after the Closing Date.  The Excepted Issuances (other than [i] above) may
be issued during the above described time periods provided such securities
are not transferable until after a time period equal to one year during
which the registration statement described in Section 10.1(iv) above has
been effective.

           12. Security Interest.  As a condition of Closing, the Company will
deliver to the Subscriber Common Shares of the Company owned by one or more
shareholders of the Company, together with signature guaranteed stock
powers.  Collectively, the foregoing stock is referred to as "Security
Shares." The Security Shares will be held by a Collateral Agent pursuant to
a Security Agreement.  Subscriber will be granted a security interest in
the Security Shares to be memorialized in the Security Agreement.  The
Company will also execute all such documents reasonably necessary to
memorialize and further protect the security interest described above.

           13. Miscellaneous.

               (a) Notices.  All notices or other communications given or

               (c) Entire Agreement; Assignment.  This Agreement
represents the entire agreement between the parties hereto with respect to
the subject matter hereof and may be amended only by a writing executed by
both parties.  No right or obligation of either party shall be assigned by
that party without prior notice to and the written consent of the other
party.

               (d) Execution.  This Agreement may be executed by
facsimile transmission, and in counterparts, each of which will be deemed
an original.

               (e) Law Governing this Agreement.  This Agreement shall be
governed by and construed in accordance with the laws of the State of New
York without regard to principles of conflicts of laws.  Any action brought
by either party against the other concerning the transactions contemplated
by this Agreement shall be brought only in the state courts of New York or
in the federal courts located in the state of New York.  Both parties and
the individuals executing this Agreement and other agreements 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.

               (f) Specific Enforcement, Consent to Jurisdiction.  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
an injunction or injunctions to prevent or cure breaches of the provisions
of this Agreement and to enforce specifically the terms and provisions
hereof or thereof, this being in addition to any other remedy to which any
of them may be entitled by law or equity.  Subject to Section 13(e) hereof,
each of the Company and Subscriber 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 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.

               (g) Confidentiality.  The Company agrees that it will not
disclose publicly or privately the identity of the Subscriber unless expressly
agreed to in writing by the Subscriber or only to the extent required by
law.

               (h) Automatic Termination.  This Agreement shall
automatically terminate without any further action of either party hereto
if the Closing shall not have occurred by the tenth (10th) business day
following the date this Agreement is accepted by the Subscriber.
