                            REGISTRATION RIGHTS AGREEMENT

     REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of
May 23, 2005, by and among CalbaTech, Inc., a Nevada corporation with
its headquarters located at 15375 Barranca Parkway, Suite I-101,
Irvine, CA 92618 (the "Company"), and each of the undersigned
(together with their respective affiliates and any assignee or
transferee of all of their respective rights hereunder, the "Initial
Investors").

     WHEREAS:

     A.  In connection with the Securities Purchase Agreement by and
among the parties hereto of even date herewith (the "Securities
Purchase Agreement"), the Company has agreed, upon the terms and
subject to the conditions contained therein, to issue and sell to the
Initial Investors (i) secured convertible notes in the aggregate
principal amount of up to Two Million Dollars ($2,000,000) (the
"Notes") that are convertible into shares of the Company's common
stock (the "Common Stock"), upon the terms and subject to the
limitations and conditions set forth in such Notes and (ii) warrants
(the "Warrants") to acquire an aggregate of 12,143,290 shares of
Common Stock, upon the terms and conditions and subject to the
limitations and conditions set forth in the Warrants; and

     B.  To induce the Initial Investors to execute and deliver the
Securities Purchase Agreement, the Company has agreed to provide
certain registration rights under the Securities Act of 1933, as
amended, and the rules and regulations thereunder, or any similar
successor statute (collectively, the "1933 Act"), and applicable
state securities laws;

     NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the
Company and each of the Initial Investors hereby agree as follows:

     1.  DEFINITIONS.

        a.  As used in this Agreement, the following terms
shall have the following meanings:

            (i)  "Investors" means the Initial Investors and
any transferee or assignee who agrees to become bound by the
provisions of this Agreement in accordance with Section 9 hereof.

            (ii)  "register," "registered," and "registration"
refer to a registration effected by preparing and filing a
Registration Statement or Statements in compliance with the 1933 Act
and pursuant to Rule 415 under the 1933 Act or any successor rule
providing for offering securities on a continuous basis ("Rule 415"),
and the declaration or ordering of effectiveness of such Registration
Statement by the United States Securities and Exchange Commission
(the "SEC").

            (iii)  "Registrable Securities" means the
Conversion Shares issued or issuable upon conversion or otherwise
pursuant to the Notes and Additional Notes (as defined in the
Securities Purchase Agreement) including, without limitation, Damages
Shares (as defined in the Notes) issued or issuable pursuant to the
Notes, shares of Common Stock issued or issuable in payment of the
Standard Liquidated Damages Amount (as defined in the Securities
Purchase Agreement), shares issued or issuable in respect of interest
or in redemption of the Notes in accordance with the terms thereof)
and Warrant Shares issuable, upon exercise or otherwise pursuant to
the Warrants and Additional Warrants (as defined in the Securities
Purchase Agreement), and any shares of capital stock issued or
issuable as a dividend on or in exchange for or otherwise with
respect to any of the foregoing.

            (iv)  "Registration Statement" means a
registration statement of the Company under the 1933 Act.

        b.  Capitalized terms used herein and not otherwise
defined herein shall have the respective meanings set forth in the
Securities Purchase Agreement or the Convertible Note.

     2.  REGISTRATION.

        a.  Mandatory Registration.  The Company shall
prepare, and, on or prior to forty-five (45) days from the date of
Closing (as defined in the Securities Purchase Agreement) (the
"Filing Date"), file with the SEC a Registration Statement on Form S-
3 (or, if Form S-3 is not then available, on such form of
Registration Statement as is then available to effect a registration
of the Registrable Securities, subject to the consent of the Initial
Investors, which consent will not be unreasonably withheld) covering
the resale of the Registrable Securities underlying the Notes and
Warrants issued or issuable pursuant to the Securities Purchase
Agreement, which Registration Statement, to the extent allowable
under the 1933 Act and the rules and regulations promulgated
thereunder (including Rule 416), shall state that such Registration
Statement also covers such indeterminate number of additional shares
of Common Stock as may become issuable upon conversion of or
otherwise pursuant to the Notes and exercise of the Warrants to
prevent dilution resulting from stock splits, stock dividends or
similar transactions.  The number of shares of Common Stock initially
included in such Registration Statement shall be no less than an
amount equal to two (2) times the sum of the number of Conversion
Shares that are then issuable upon conversion of the Notes and
Additional Notes (based on the Variable Conversion Price as would
then be in effect and assuming the Variable Conversion Price is the
Conversion Price at such time), and the number of Warrant Shares that
are then issuable upon exercise of the Warrants, without regard to
any limitation on the Investor's ability to convert the Notes or
exercise the Warrants.  The Company acknowledges that the number of
shares initially included in the Registration Statement represents a
good faith estimate of the maximum number of shares issuable upon
conversion of the Notes and upon exercise of the Warrants.

        b.  Underwritten Offering.  If any offering pursuant
to a Registration Statement pursuant to Section 2(a) hereof involves
an underwritten offering, the Investors who hold a majority in
interest of the Registrable Securities subject to such underwritten
offering, with the consent of a majority-in-interest of the Initial
Investors, shall have the right to select one legal counsel and an
investment banker or bankers and manager or managers to administer
the offering, which investment banker or bankers or manager or
managers shall be reasonably satisfactory to the Company.

        c.  Payments by the Company.  The Company shall use
its best efforts to obtain effectiveness of the Registration
Statement as soon as practicable.  If (i) the Registration
Statement(s) covering the Registrable Securities required to be filed
by the Company pursuant to Section 2(a) hereof is not filed by the
Filing Date or declared effective by the SEC on or prior to one
hundred (100) days from the date of Closing (as defined in the
Securities Purchase Agreement), or (ii) after the Registration
Statement has been declared effective by the SEC, sales of all of the
Registrable Securities cannot be made pursuant to the Registration
Statement, or (iii) the Common Stock is not listed or included for
quotation on the Nasdaq National Market ("Nasdaq"), the Nasdaq
SmallCap Market ("Nasdaq SmallCap"), the New York Stock Exchange (the
"NYSE") or the American Stock Exchange (the "AMEX") after being so
listed or included for quotation, or (iv) the Common Stock ceases to
be traded on the Over-the-Counter Bulletin Board (the "OTCBB") or any
equivalent replacement exchange prior to being listed or included for
quotation on one of the aforementioned markets, then the Company will
make payments to the Investors in such amounts and at such times as
shall be determined pursuant to this Section 2(c) as partial relief
for the damages to the Investors by reason of any such delay in or
reduction of their ability to sell the Registrable Securities (which
remedy shall not be exclusive of any other remedies available at law
or in equity).  The Company shall pay to each holder of the Notes or
Registrable Securities an amount equal to the then outstanding
principal amount of the Notes (and, in the case of holders of
Registrable Securities, the principal amount of Notes from which such
Registrable Securities were converted) ("Outstanding Principal
Amount"), multiplied by the Applicable Percentage (as defined below)
times the sum of:  (i) the number of months (prorated for partial
months) after the Filing Date or the end of the aforementioned one
hundred (100) day period and prior to the date the Registration
Statement is declared effective by the SEC, provided, however, that
there shall be excluded from such period any delays which are solely
attributable to changes required by the Investors in the Registration
Statement with respect to information relating to the Investors,
including, without limitation, changes to the plan of distribution,
or to the failure of the Investors to conduct their review of the
Registration Statement pursuant to Section 3(h) below in a reasonably
prompt manner; (ii) the number of months (prorated for partial
months) that sales of all of the Registrable Securities cannot be
made pursuant to the Registration Statement after the Registration
Statement has been declared effective (including, without limitation,
when sales cannot be made by reason of the Company's failure to
properly supplement or amend the prospectus included therein in
accordance with the terms of this Agreement, but excluding any days
during an Allowed Delay (as defined in Section 3(f)); and (iii) the
number of months (prorated for partial months) that the Common Stock
is not listed or included for quotation on the OTCBB, Nasdaq, Nasdaq
SmallCap, NYSE or AMEX or that trading thereon is halted after the
Registration Statement has been declared effective.  The term
"Applicable Percentage" means two hundredths (.02).  (For example, if
the Registration Statement becomes effective one (1) month after the
end of such one hundred (100) day period, the Company would pay
$5,000 for each $250,000 of Outstanding Principal Amount.  If
thereafter, sales could not be made pursuant to the Registration
Statement for an additional period of one (1) month, the Company
would pay an additional $5,000 for each $250,000 of Outstanding
Principal Amount.)  Such amounts shall be paid in cash or, at the
Company's option, in shares of Common Stock priced at the Conversion
Price (as defined in the Notes) on such payment date.

        d.  Piggy-Back Registrations.  Subject to the last
sentence of this Section 2(d), if at any time prior to the expiration
of the Registration Period (as hereinafter defined) the Company shall
determine to file with the SEC a Registration Statement relating to
an offering for its own account or the account of others under the
1933 Act of any of its equity securities (other than on Form S-4 or
Form S-8 or their then equivalents relating to equity securities to
be issued solely in connection with any acquisition of any entity or
business or equity securities issuable in connection with stock
option or other bona fide, employee benefit plans), the Company shall
send to each Investor who is entitled to registration rights under
this Section 2(d) written notice of such determination and, if within
fifteen (15) days after the effective date of such notice, such
Investor shall so request in writing, the Company shall include in
such Registration Statement all or any part of the Registrable
Securities such Investor requests to be registered, except that if,
in connection with any underwritten public offering for the account
of the Company the managing underwriter(s) thereof shall impose a
limitation on the number of shares of Common Stock which may be
included in the Registration Statement because, in such
underwriter(s)' judgment, marketing or other factors dictate such
limitation is necessary to facilitate public distribution, then the
Company shall be obligated to include in such Registration Statement
only such limited portion of the Registrable Securities with respect
to which such Investor has requested inclusion hereunder as the
underwriter shall permit. Any exclusion of Registrable Securities
shall be made pro rata among the Investors seeking to include
Registrable Securities in proportion to the number of Registrable
Securities sought to be included by such Investors; provided,
however, that the Company shall not exclude any Registrable
Securities unless the Company has first excluded all outstanding
securities, the holders of which are not entitled to inclusion of
such securities in such Registration Statement or are not entitled to
pro rata inclusion with the Registrable Securities; and provided,
further, however, that, after giving effect to the immediately
preceding proviso, any exclusion of Registrable Securities shall be
made pro rata with holders of other securities having the right to
include such securities in the Registration Statement other than
holders of securities entitled to inclusion of their securities in
such Registration Statement by reason of demand registration rights.
No right to registration of Registrable Securities under this Section
2(d) shall be construed to limit any registration required under
Section 2(a) hereof.  If an offering in connection with which an
Investor is entitled to registration under this Section 2(d) is an
underwritten offering, then each Investor whose Registrable
Securities are included in such Registration Statement shall, unless
otherwise agreed by the Company, offer and sell such Registrable
Securities in an underwritten offering using the same underwriter or
underwriters and, subject to the provisions of this Agreement, on the
same terms and conditions as other shares of Common Stock included in
such underwritten offering.  Notwithstanding anything to the contrary
set forth herein, the registration rights of the Investors pursuant
to this Section 2(d) shall only be available in the event the Company
fails to timely file, obtain effectiveness or maintain effectiveness
of any Registration Statement to be filed pursuant to Section 2(a) in
accordance with the terms of this Agreement.

        e.  Eligibility for Form S-3, SB-2 or S-1; Conversion
to Form S-3.  The Company represents and warrants that it meets the
requirements for the use of Form S-3, SB-2 or S-1 for registration of
the sale by the Initial Investors and any other Investors of the
Registrable Securities.   The Company agrees to file all reports
required to be filed by the Company with the SEC in a timely manner
so as to remain eligible or become eligible, as the case may be, and
thereafter to maintain its eligibility, for the use of Form S-3.  If
the Company is not currently eligible to use Form S-3, not later than
five (5) business days after the Company first meets the registration
eligibility and transaction requirements for the use of Form S-3 (or
any successor form) for registration of the offer and sale by the
Initial Investors and any other Investors of Registrable Securities,
the Company shall file a Registration Statement on Form S-3 (or such
successor form) with respect to the Registrable Securities covered by
the Registration Statement on Form SB-2 or Form S-1, whichever is
applicable, filed pursuant to Section 2(a) (and include in such
Registration Statement on Form S-3 the information required by Rule
429 under the 1933 Act) or convert the Registration Statement on Form
SB-2 or Form S-1, whichever is applicable, filed pursuant to Section
2(a) to a Form S-3 pursuant to Rule 429 under the 1933 Act and cause
such Registration Statement (or such amendment) to be declared
effective no later than forty-five (45) days after filing.  In the
event of a breach by the Company of the provisions of this Section
2(e), the Company will be required to make payments pursuant to
Section 2(c) hereof.

     3.  OBLIGATIONS OF THE COMPANY.

     In connection with the registration of the Registrable
Securities, the Company shall have the following obligations:

        a.  The Company shall prepare promptly, and file with
the SEC not later than the Filing Date, a Registration Statement with
respect to the number of Registrable Securities provided in Section
2(a), and thereafter use its best efforts to cause such Registration
Statement relating to Registrable Securities to become effective as
soon as possible after such filing but in no event later than one
hundred (100) days from the date of Closing), and keep the
Registration Statement effective pursuant to Rule 415 at all times
until such date as is the earlier of (i) the date on which all of the
Registrable Securities have been sold and (ii) the date on which the
Registrable Securities (in the opinion of counsel to the Initial
Investors) may be immediately sold to the public without registration
or restriction (including, without limitation, as to volume by each
holder thereof) under the 1933 Act (the "Registration Period"), which
Registration Statement (including any amendments or supplements
thereto and prospectuses contained therein) shall not contain any
untrue statement of a material fact or omit to state a material fact
required to be stated therein, or necessary to make the statements
therein not misleading.

        b.  The Company shall prepare and file with the SEC
such amendments (including post-effective amendments) and supplements
to the Registration Statements and the prospectus used in connection
with the Registration Statements as may be necessary to keep the
Registration Statements effective at all times during the
Registration Period, and, during such period, comply with the
provisions of the 1933 Act with respect to the disposition of all
Registrable Securities of the Company covered by the Registration
Statements until such time as all of such Registrable Securities have
been disposed of in accordance with the intended methods of
disposition by the seller or sellers thereof as set forth in the
Registration Statements.  In the event the number of shares available
under a Registration Statement filed pursuant to this Agreement is
insufficient to cover all of the Registrable Securities issued or
issuable upon conversion of the Notes and exercise of the Warrants,
the Company shall amend the Registration Statement, or file a new
Registration Statement (on the short form available therefor, if
applicable), or both, so as to cover all of the Registrable
Securities, in each case, as soon as practicable, but in any event
within fifteen (15) days after the necessity therefor arises (based
on the market price of the Common Stock and other relevant factors on
which the Company reasonably elects to rely).  The Company shall use
its best efforts to cause such amendment and/or new Registration
Statement to become effective as soon as practicable following the
filing thereof, but in any event within thirty (30) days after the
date on which the Company reasonably first determines (or reasonably
should have determined) the need therefor.  The provisions of Section
2(c) above shall be applicable with respect to such obligation, with
the one hundred (100) days running from the day the Company
reasonably first determines (or reasonably should have determined)
the need therefor.

        c.  The Company shall furnish to each Investor whose
Registrable Securities are included in a Registration Statement and
its legal counsel (i) promptly (but in no event more than two (2)
business days) after the same is prepared and publicly distributed,
filed with the SEC, or received by the Company, one copy of each
Registration Statement and any amendment thereto, each preliminary
prospectus and prospectus and each amendment or supplement thereto,
and, in the case of the Registration Statement referred to in Section
2(a), each letter written by or on behalf of the Company to the SEC
or the staff of the SEC, and each item of correspondence from the SEC
or the staff of the SEC, in each case relating to such Registration
Statement (other than any portion of any thereof which contains
information for which the Company has sought confidential treatment),
and (ii) promptly (but in no event more than two (2) business days)
after the Registration Statement is declared effective by the SEC,
such number of copies of a prospectus, including a preliminary
prospectus, and all amendments and supplements thereto and such other
documents as such Investor may reasonably request in order to
facilitate the disposition of the Registrable Securities owned by
such Investor.  The Company will immediately notify each Investor by
facsimile of the effectiveness of each Registration Statement or any
post-effective amendment.  The Company will promptly (but in no event
more than ten (10) business days) respond to any and all comments
received from the SEC (which comments shall promptly be made
available to the Investors upon request), with a view towards causing
each Registration Statement or any amendment thereto to be declared
effective by the SEC as soon as practicable, shall promptly file an
acceleration request as soon as practicable (but in no event more
than two (2) business days) following the resolution or clearance of
all SEC comments or, if applicable, following notification by the SEC
that any such Registration Statement or any amendment thereto will
not be subject to review and shall, if required by SEC rules,
promptly file with the SEC a final prospectus as soon as practicable
(but in no event more than two (2) business days) following receipt
by the Company from the SEC of an order declaring the Registration
Statement effective.  In the event of a breach by the Company of the
provisions of this Section 3(c), the Company will be required to make
payments pursuant to Section 2(c) hereof.

        d.  The Company shall use reasonable efforts to (i)
register and qualify the Registrable Securities covered by the
Registration Statements under such other securities or "blue sky"
laws of such jurisdictions in the United States as the Investors who
hold a majority in interest of the Registrable Securities being
offered reasonably request, (ii) prepare and file in those
jurisdictions such amendments (including post-effective amendments)
and supplements to such registrations and qualifications as may be
necessary to maintain the effectiveness thereof during the
Registration Period, (iii) take such other actions as may be
necessary to maintain such registrations and qualifications in effect
at all times during the Registration Period, and (iv) take all other
actions reasonably necessary or advisable to qualify the Registrable
Securities for sale in such jurisdictions; provided, however, that
the Company shall not be required in connection therewith or as a
condition thereto to (a) qualify to do business in any jurisdiction
where it would not otherwise be required to qualify but for this
Section 3(d), (b) subject itself to general taxation in any such
jurisdiction, (c) file a general consent to service of process in any
such jurisdiction, (d) provide any undertakings that cause the
Company undue expense or burden, or (e) make any change in its
charter or bylaws, which in each case the Board of Directors of the
Company determines to be contrary to the best interests of the
Company and its shareholders.

        e.  In the event Investors who hold a majority-in-
interest of the Registrable Securities being offered in the offering
(with the approval of a majority-in-interest of the Initial
Investors) select underwriters for the offering, the Company shall
enter into and perform its obligations under an underwriting
agreement, in usual and customary form, including, without
limitation, customary indemnification and contribution obligations,
with the underwriters of such offering.

        f.  As promptly as practicable after becoming aware
of such event, the Company shall notify each Investor of the
happening of any event, of which the Company has knowledge, as a
result of which the prospectus included in any Registration
Statement, as then in effect, includes an untrue statement of a
material fact or omission to state a material fact required to be
stated therein or necessary to make the statements therein not
misleading, and use its best efforts promptly to prepare a supplement
or amendment to any Registration Statement to correct such untrue
statement or omission, and deliver such number of copies of such
supplement or amendment to each Investor as such Investor may
reasonably request; provided that, for not more than ten (10)
consecutive trading days (or a total of not more than twenty (20)
trading days in any twelve (12) month period), the Company may delay
the disclosure of material non-public information concerning the
Company (as well as prospectus or Registration Statement updating)
the disclosure of which at the time is not, in the good faith opinion
of the Company, in the best interests of the Company (an "Allowed
Delay"); provided, further, that the Company shall promptly (i)
notify the Investors in writing of the existence of (but in no
event, without the prior written consent of an Investor, shall the
Company disclose to such investor any of the facts or circumstances
regarding) material non-public information giving rise to an Allowed
Delay and (ii) advise the Investors in writing to cease all sales
under such Registration Statement until the end of the Allowed Delay.
Upon expiration of the Allowed Delay, the Company shall again be
bound by the first sentence of this Section 3(f) with respect to the
information giving rise thereto.

        g.  The Company shall use its best efforts to prevent
the issuance of any stop order or other suspension of effectiveness
of any Registration Statement, and, if such an order is issued, to
obtain the withdrawal of such order at the earliest possible moment
and to notify each Investor who holds Registrable Securities being
sold (or, in the event of an underwritten offering, the managing
underwriters) of the issuance of such order and the resolution thereof.

        h.  The Company shall permit a single firm of counsel
designated by the Initial Investors to review such Registration
Statement and all amendments and supplements thereto (as well as all
requests for acceleration or effectiveness thereof) a reasonable
period of time prior to their filing with the SEC, and not file any
document in a form to which such counsel reasonably objects and will
not request acceleration of such Registration Statement without prior
notice to such counsel.  The sections of such Registration Statement
covering information with respect to the Investors, the Investor's
beneficial ownership of securities of the Company or the Investors
intended method of disposition of Registrable Securities shall
conform to the information provided to the Company by each of the
Investors.

        i.  The Company shall make generally available to its
security holders as soon as practicable, but not later than ninety
(90) days after the close of the period covered thereby, an earnings
statement (in form complying with the provisions of Rule 158 under
the 1933 Act) covering a twelve-month period beginning not later than
the first day of the Company's fiscal quarter next following the
effective date of the Registration Statement.

        j.  At the request of any Investor, the Company shall
furnish, on the date that Registrable Securities are delivered to an
underwriter, if any, for sale in connection with any Registration
Statement or, if such securities are not being sold by an
underwriter, on the date of effectiveness thereof (i) an opinion,
dated as of such date, from counsel representing the Company for
purposes of such Registration Statement, in form, scope and substance
as is customarily given in an underwritten public offering, addressed
to the underwriters, if any, and the Investors and (ii) a letter,
dated such date, from the Company's independent certified public
accountants in form and substance as is customarily given by
independent certified public accountants to underwriters in an
underwritten public offering, addressed to the underwriters, if any,
and the Investors.

        k.  The Company shall make available for inspection
by (i) any Investor, (ii) any underwriter participating in any
disposition pursuant to a Registration Statement, (iii) one firm of
attorneys and one firm of accountants or other agents retained by the
Initial Investors, (iv) one firm of attorneys and one firm of
accountants or other agents retained by all other Investors, and (v)
one firm of attorneys retained by all such underwriters
(collectively, the "Inspectors") all pertinent financial and other
records, and pertinent corporate documents and properties of the
Company, including without limitation, records of conversions by
other holders of convertible securities issued by the Company and the
issuance of stock to such holders pursuant to the conversions
(collectively, the "Records"), as shall be reasonably deemed
necessary by each Inspector to enable each Inspector to exercise its
due diligence responsibility, and cause the Company's officers,
directors and employees to supply all information which any Inspector
may reasonably request for purposes of such due diligence; provided,
however, that each Inspector shall hold in confidence and shall not
make any disclosure (except to an Investor) of any Record or other
information which the Company determines in good faith to be
confidential, and of which determination the Inspectors are so
notified, unless (a) the disclosure of such Records is necessary to
avoid or correct a misstatement or omission in any Registration
Statement, (b) the release of such Records is ordered pursuant to a
subpoena or other order from a court or government body of competent
jurisdiction, or (c) the information in such Records has been made
generally available to the public other than by disclosure in
violation of this or any other agreement.  The Company shall not be
required to disclose any confidential information in such Records to
any Inspector until and unless such Inspector shall have entered into
confidentiality agreements (in form and substance satisfactory to the
Company) with the Company with respect thereto, substantially in the
form of this Section 3(k).  Each Investor agrees that it shall, upon
learning that disclosure of such Records is sought in or by a court
or governmental body of competent jurisdiction or through other
means, give prompt notice to the Company and allow the Company, at
its expense, to undertake appropriate action to prevent disclosure
of, or to obtain a protective order for, the Records deemed
confidential.  Nothing herein (or in any other confidentiality
agreement between the Company and any Investor) shall be deemed to
limit the Investor's ability to sell Registrable Securities in a
manner which is otherwise consistent with applicable laws and
regulations.

        l.  The Company shall hold in confidence and not make
any disclosure of information concerning an Investor provided to the
Company unless (i) disclosure of such information is necessary to
comply with federal or state securities laws, (ii) the disclosure of
such information is necessary to avoid or correct a misstatement or
omission in any Registration Statement, (iii) the release of such
information is ordered pursuant to a subpoena or other order from a
court or governmental body of competent jurisdiction, or (iv) such
information has been made generally available to the public other
than by disclosure in violation of this or any other agreement.  The
Company agrees that it shall, upon learning that disclosure of such
information concerning an Investor is sought in or by a court or
governmental body of competent jurisdiction or through other means,
give prompt notice to such Investor prior to making such disclosure,
and allow the Investor, at its expense, to undertake appropriate
action to prevent disclosure of, or to obtain a protective order for,
such information.

        m.  The Company shall (i) cause all the Registrable
Securities covered by the Registration Statement to be listed on each
national securities exchange on which securities of the same class or
series issued by the Company are then listed, if any, if the listing
of such Registrable Securities is then permitted under the rules of
such exchange, or (ii) to the extent the securities of the same class
or series are not then listed on a national securities exchange,
secure the designation and quotation, of all the Registrable
Securities covered by the Registration Statement on Nasdaq or, if not
eligible for Nasdaq, on Nasdaq SmallCap or, if not eligible for
Nasdaq or Nasdaq SmallCap, on the OTCBB and, without limiting the
generality of the foregoing, to arrange for at least two market
makers to register with the National Association of Securities
Dealers, Inc. ("NASD") as such with respect to such Registrable
Securities.

        n.  The Company shall provide a transfer agent and
registrar, which may be a single entity, for the Registrable
Securities not later than the effective date of the Registration
Statement.

        o.  The Company shall cooperate with the Investors
who hold Registrable Securities being offered and the managing
underwriter or underwriters, if any, to facilitate the timely
preparation and delivery of certificates (not bearing any restrictive
legends) representing Registrable Securities to be offered pursuant
to a Registration Statement and enable such certificates to be in
such denominations or amounts, as the case may be, as the managing
underwriter or underwriters, if any, or the Investors may reasonably
request and registered in such names as the managing underwriter or
underwriters, if any, or the Investors may request, and, within three
(3) business days after a Registration Statement which includes
Registrable Securities is ordered effective by the SEC, the Company
shall deliver, and shall cause legal counsel selected by the Company
to deliver, to the transfer agent for the Registrable Securities
(with copies to the Investors whose Registrable Securities are
included in such Registration Statement) an instruction in the form
attached hereto as Exhibit 1 and an opinion of such counsel in the
form attached hereto as Exhibit 2.

        p.  At the request of the holders of a majority-in-
interest of the Registrable Securities, the Company shall prepare and
file with the SEC such amendments (including post-effective
amendments) and supplements to a Registration Statement and any
prospectus used in connection with the Registration Statement as may
be necessary in order to change the plan of distribution set forth in
such Registration Statement.

        q.  From and after the date of this Agreement, the
Company shall not, and shall not agree to, allow the holders of any
securities of the Company to include any of their securities in any
Registration Statement under Section 2(a) hereof or any amendment or
supplement thereto under Section 3(b) hereof without the consent of
the holders of a majority-in-interest of the Registrable Securities.

        r.  The Company shall take all other reasonable
actions necessary to expedite and facilitate disposition by the
Investors of Registrable Securities pursuant to a Registration
Statement.

     4.  OBLIGATIONS OF THE INVESTORS.

     In connection with the registration of the Registrable
Securities, the Investors shall have the following obligations:

        a.  It shall be a condition precedent to the
obligations of the Company to complete the registration pursuant to
this Agreement with respect to the Registrable Securities of a
particular Investor that such Investor shall furnish to the Company
such information regarding itself, the Registrable Securities held by
it and the intended method of disposition of the Registrable
Securities held by it as shall be reasonably required to effect the
registration of such Registrable Securities and shall execute such
documents in connection with such registration as the Company may
reasonably request.  At least three (3) business days prior to the
first anticipated filing date of the Registration Statement, the
Company shall notify each Investor of the information the Company
requires from each such Investor.

        b.  Each Investor, by such Investor's acceptance of
the Registrable Securities, agrees to cooperate with the Company as
reasonably requested by the Company in connection with the
preparation and filing of the Registration Statements hereunder,
unless such Investor has notified the Company in writing of such
Investor's election to exclude all of such Investor's Registrable
Securities from the Registration Statements.

        c.  In the event Investors holding a majority-in-
interest of the Registrable Securities being registered (with the
approval of the Initial Investors) determine to engage the services
of an underwriter, each Investor agrees to enter into and perform
such Investor's obligations under an underwriting agreement, in usual
and customary form, including, without limitation, customary
indemnification and contribution obligations, with the managing
underwriter of such offering and take such other actions as are
reasonably required in order to expedite or facilitate the
disposition of the Registrable Securities, unless such Investor has
notified the Company in writing of such Investor's election to
exclude all of such Investor's Registrable Securities from such
Registration Statement.

        d.  Each Investor agrees that, upon receipt of any
notice from the Company of the happening of any event of the kind
described in Section 3(f) or 3(g), such Investor will immediately
discontinue disposition of Registrable Securities pursuant to the
Registration Statement covering such Registrable Securities until
such Investor's receipt of the copies of the supplemented or amended
prospectus contemplated by Section 3(f) or 3(g) and, if so directed
by the Company, such Investor shall deliver to the Company (at the
expense of the Company) or destroy (and deliver to the Company a
certificate of destruction) all copies in such Investor's possession,
of the prospectus covering such Registrable Securities current at the
time of receipt of such notice.

        e.  No Investor may participate in any underwritten
registration hereunder unless such Investor (i) agrees to sell such
Investor's Registrable Securities on the basis provided in any
underwriting arrangements in usual and customary form entered into by
the Company, (ii) completes and executes all questionnaires, powers
of attorney, indemnities, underwriting agreements and other documents
reasonably required under the terms of such underwriting
arrangements, and (iii) agrees to pay its pro rata share of all
underwriting discounts and commissions and any expenses in excess of
those payable by the Company pursuant to Section 5 below.

     5.  EXPENSES OF REGISTRATION.

     All reasonable expenses, other than underwriting discounts and
commissions, incurred in connection with registrations, filings or
qualifications pursuant to Sections 2 and 3, including, without
limitation, all registration, listing and qualification fees,
printers and accounting fees, the fees and disbursements of counsel
for the Company, and the reasonable fees and disbursements of one
counsel selected by the Initial Investors pursuant to Sections 2(b)
and 3(h) hereof shall be borne by the Company.

     6.  INDEMNIFICATION.

     In the event any Registrable Securities are included in a
Registration Statement under this Agreement:

        a.  To the extent permitted by law, the Company will
indemnify, hold harmless and defend (i) each Investor who holds such
Registrable Securities, (ii) the directors, officers, partners,
employees, agents and each person who controls any Investor within
the meaning of the 1933 Act or the Securities Exchange Act of 1934,
as amended (the "1934 Act"), if any, (iii) any underwriter (as
defined in the 1933 Act) for the Investors, and (iv) the directors,
officers, partners, employees and each person who controls any such
underwriter within the meaning of the 1933 Act or the 1934 Act, if
any (each, an "Indemnified Person"), against any joint or several
losses, claims, damages, liabilities or expenses (collectively,
together with actions, proceedings or inquiries by any regulatory or
self-regulatory organization, whether commenced or threatened, in
respect thereof, "Claims") to which any of them may become subject
insofar as such Claims arise out of or are based upon: (i) any untrue
statement or alleged untrue statement of a material fact in a
Registration Statement or the omission or alleged omission to state
therein a material fact required to be stated or necessary to make
the statements therein not misleading; (ii) any untrue statement or
alleged untrue statement of a material fact contained in any
preliminary prospectus if used prior to the effective date of such
Registration Statement, or contained in the final prospectus (as
amended or supplemented, if the Company files any amendment thereof
or supplement thereto with the SEC) or the omission or alleged
omission to state therein any material fact necessary to make the
statements made therein, in light of the circumstances under which
the statements therein were made, not misleading; or (iii) any
violation or alleged violation by the Company of the 1933 Act, the
1934 Act, any other law, including, without limitation, any state
securities law, or any rule or regulation thereunder relating to the
offer or sale of the Registrable Securities (the matters in the
foregoing clauses (i) through (iii) being, collectively,
"Violations").  Subject to the restrictions set forth in Section 6(c)
with respect to the number of legal counsel, the Company shall
reimburse the Indemnified Person, promptly as such expenses are
incurred and are due and payable, for any reasonable legal fees or
other reasonable expenses incurred by them in connection with
investigating or defending any such Claim.  Notwithstanding anything
to the contrary contained herein, the indemnification agreement
contained in this Section 6(a): (i) shall not apply to a Claim
arising out of or based upon a Violation which occurs in reliance
upon and in conformity with information furnished in writing to the
Company by any Indemnified Person or underwriter for such Indemnified
Person expressly for use in connection with the preparation of such
Registration Statement or any such amendment thereof or supplement
thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(c) hereof; (ii) shall not apply to amounts paid
in settlement of any Claim if such settlement is effected without the
prior written consent of the Company, which consent shall not be
unreasonably withheld; and (iii) with respect to any preliminary
prospectus, shall not inure to the benefit of any Indemnified Person
if the untrue statement or omission of material fact contained in the
preliminary prospectus was corrected on a timely basis in the
prospectus, as then amended or supplemented, such corrected
prospectus was timely made available by the Company pursuant to
Section 3(c) hereof, and the Indemnified Person was promptly advised
in writing not to use the incorrect prospectus prior to the use
giving rise to a Violation and such Indemnified Person,
notwithstanding such advice, used it.  Such indemnity shall remain in
full force and effect regardless of any investigation made by or on
behalf of the Indemnified Person and shall survive the transfer of
the Registrable Securities by the Investors pursuant to Section 9.

        b.  In connection with any Registration Statement in
which an Investor is participating, each such Investor agrees
severally and not jointly to indemnify, hold harmless and defend, to
the same extent and in the same manner set forth in Section 6(a), the
Company, each of its directors, each of its officers who signs the
Registration Statement, each person, if any, who controls the Company
within the meaning of the 1933 Act or the 1934 Act, any underwriter
and any other shareholder selling securities pursuant to the
Registration Statement or any of its directors or officers or any
person who controls such shareholder or underwriter within the
meaning of the 1933 Act or the 1934 Act (collectively and together
with an Indemnified Person, an "Indemnified Party"), against any
Claim to which any of them may become subject, under the 1933 Act,
the 1934 Act or otherwise, insofar as such Claim arises out of or is
based upon any Violation by such Investor, in each case to the extent
(and only to the extent) that such Violation occurs in reliance upon
and in conformity with written information furnished to the Company
by such Investor expressly for use in connection with such
Registration Statement; and subject to Section 6(c) such Investor
will reimburse any legal or other expenses (promptly as such expenses
are incurred and are due and payable) reasonably incurred by them in
connection with investigating or defending any such Claim; provided,
however, that the indemnity agreement contained in this Section 6(b)
shall not apply to amounts paid in settlement of any Claim if such
settlement is effected without the prior written consent of such
Investor, which consent shall not be unreasonably withheld; provided,
further, however, that the Investor shall be liable under this
Agreement (including this Section 6(b) and Section 7) for only that
amount as does not exceed the net proceeds to such Investor as a
result of the sale of Registrable Securities pursuant to such
Registration Statement.  Such indemnity shall remain in full force
and effect regardless of any investigation made by or on behalf of
such Indemnified Party and shall survive the transfer of the
Registrable Securities by the Investors pursuant to Section 9.
Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 6(b) with respect
to any preliminary prospectus shall not inure to the benefit of any
Indemnified Party if the untrue statement or omission of material
fact contained in the preliminary prospectus was corrected on a
timely basis in the prospectus, as then amended or supplemented.

        c.  Promptly after receipt by an Indemnified Person
or Indemnified Party under this Section 6 of notice of the
commencement of any action (including any governmental action), such
Indemnified Person or Indemnified Party shall, if a Claim in respect
thereof is to be made against any indemnifying party under this
Section 6, deliver to the indemnifying party a written notice of the
commencement thereof, and the indemnifying party shall have the right
to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed,
to assume control of the defense thereof with counsel mutually
satisfactory to the indemnifying party and the Indemnified Person or
the Indemnified Party, as the case may be; provided, however, that an
Indemnified Person or Indemnified Party shall have the right to
retain its own counsel with the fees and expenses to be paid by the
indemnifying party, if, in the reasonable opinion of counsel retained
by the indemnifying party, the representation by such counsel of the
Indemnified Person or Indemnified Party and the indemnifying party
would be inappropriate due to actual or potential differing interests
between such Indemnified Person or Indemnified Party and any other
party represented by such counsel in such proceeding.  The
indemnifying party shall pay for only one separate legal counsel for
the Indemnified Persons or the Indemnified Parties, as applicable,
and such legal counsel shall be selected by Investors holding a
majority-in-interest of the  Registrable Securities included in the
Registration Statement to which the Claim relates (with the approval
of a majority-in-interest of the Initial Investors), if the Investors
are entitled to indemnification hereunder, or the Company, if the
Company is entitled to indemnification hereunder, as applicable.  The
failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall not
relieve such indemnifying party of any liability to the Indemnified
Person or Indemnified Party under this Section 6, except to the
extent that the indemnifying party is actually prejudiced in its
ability to defend such action.  The indemnification required by this
Section 6 shall be made by periodic payments of the amount thereof
during the course of the investigation or defense, as such expense,
loss, damage or liability is incurred and is due and payable.

     7.  CONTRIBUTION.

     To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party agrees to make
the maximum contribution with respect to any amounts for which it
would otherwise be liable under Section 6 to the fullest extent
permitted by law; provided, however, that (i) no contribution shall
be made under circumstances where the maker would not have been
liable for indemnification under the fault standards set forth in
Section 6, (ii) no seller of Registrable Securities guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of
the 1933 Act) shall be entitled to contribution from any seller of
Registrable Securities who was not guilty of such fraudulent
misrepresentation, and (iii)contribution (together with any
indemnification or other obligations under this Agreement) by any
seller of Registrable Securities shall be limited in amount to the
net amount of proceeds received by such seller from the sale of such
Registrable Securities.

     8.  REPORTS UNDER THE 1934 ACT.

     With a view to making available to the Investors the benefits of
Rule 144 promulgated under the 1933 Act or any other similar rule or
regulation of the SEC that may at any time permit the investors to
sell securities of the Company to the public without registration
("Rule 144"), the Company agrees to:

        a.  make and keep public information available, as
those terms are understood and defined in Rule 144;

        b.  file with the SEC in a timely manner all reports
and other documents required of the Company under the 1933 Act and
the 1934 Act so long as the Company remains subject to such
requirements (it being understood that nothing herein shall limit the
Company's obligations under Section 4(c) of the Securities Purchase
Agreement) and the filing of such reports and other documents is
required for the applicable provisions of Rule 144; and

        c.  furnish to each Investor so long as such Investor
owns Registrable Securities, promptly upon request, (i) a written
statement by the Company that it has complied with the reporting
requirements of Rule 144, the 1933 Act and the 1934 Act, (ii) a copy
of the most recent annual or quarterly report of the Company and such
other reports and documents so filed by the Company, and (iii) such
other information as may be reasonably requested to permit the
Investors to sell such securities pursuant to Rule 144 without
registration.

     9.  ASSIGNMENT OF REGISTRATION RIGHTS.

     The rights under this Agreement shall be automatically
assignable by the Investors to any transferee of all or any portion
of Registrable Securities if: (i) the Investor agrees in writing with
the transferee or assignee to assign such rights, and a copy of such
agreement is furnished to the Company within a reasonable time after
such assignment, (ii) the Company is, within a reasonable time after
such transfer or assignment, furnished with written notice of (a) the
name and address of such transferee or assignee, and (b) the
securities with respect to which such registration rights are being
transferred or assigned, (iii) following such transfer or assignment,
the further disposition of such securities by the transferee or
assignee is restricted under the 1933 Act and applicable state
securities laws, (iv) at or before the time the Company receives the
written notice contemplated by clause (ii) of this sentence, the
transferee or assignee agrees in writing with the Company to be bound
by all of the provisions contained herein, (v) such transfer shall
have been made in accordance with the applicable requirements of the
Securities Purchase Agreement, and (vi) such transferee shall be an
"accredited investor" as that term defined in Rule 501 of Regulation
D promulgated under the 1933 Act.

     10.  AMENDMENT OF REGISTRATION RIGHTS.

     Provisions of this Agreement may be amended and the observance
thereof may be waived (either generally or in a particular instance
and either retroactively or prospectively), only with written consent
of the Company, each of the Initial Investors (to the extent such
Initial Investor still owns Registrable Securities) and Investors who
hold a majority interest of the Registrable Securities.  Any
amendment or waiver effected in accordance with this Section 10 shall
be binding upon each Investor and the Company.

     11.  MISCELLANEOUS.

        a.  A person or entity is deemed to be a holder of
Registrable Securities whenever such person or entity owns of record
such Registrable Securities.  If the Company receives conflicting
instructions, notices or elections from two or more persons or
entities with respect to the same Registrable Securities, the Company
shall act upon the basis of instructions, notice or election received
from the registered owner of such Registrable Securities.

        b.  Any notices required or permitted to be given
under the terms hereof shall be sent by certified or registered mail
(return receipt requested) or delivered personally or by courier
(including a recognized overnight delivery service) or by facsimile
and shall be effective five days after being placed in the mail, if
mailed by regular United States mail, or upon receipt, if delivered

service) or by facsimile, in each case addressed to a party.  The

the Company of this Agreement and the filings contemplated therein
have been duly authorized by all necessary action on the part of the
Company and no further action is required by the Company.  This
Agreement constitutes a legal, valid and binding obligation of the
Company enforceable in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement
of creditor's rights generally.

        (b)  The Company represents and warrants that it has no
place of business or offices where its respective books of account
and records are kept (other than temporarily at the offices of its
attorneys or accountants) or places where Collateral is stored or
located, except as set forth on Schedule A attached hereto;

        (c)  The Company is the sole owner of the Collateral
(except for non-exclusive licenses granted by the Company in the
ordinary course of business), free and clear of any liens, security
interests, encumbrances, rights or claims, except as provided in its
SEC filings, and is fully authorized to grant the Security Interest
in and to pledge the Collateral.  There is not on file in any
governmental or regulatory authority, agency or recording office an
effective financing statement, security agreement, license or
transfer or any notice of any of the foregoing (other than those that
have been filed in favor of the Secured Party pursuant to this
Agreement) covering or affecting any of the  Collateral.  So long as
this Agreement shall be in effect, the Company shall not execute and
shall not knowingly permit to be on file in any such office or agency
any such financing statement or other document or instrument (except
to the extent filed or recorded in favor of the Secured Party
pursuant to the terms of this Agreement).

        (d)  No part of the Collateral has been judged invalid or
unenforceable.  No written claim has been received that any
Collateral or the Company's use of any Collateral violates the rights
of any third party. There has been no adverse decision to the
Company's claim of ownership rights in or exclusive rights to use the
Collateral in any jurisdiction or to the Company's right to keep and
maintain such Collateral in full force and effect, and there is no
proceeding involving said rights pending or, to the best knowledge of
the Company, threatened before any court, judicial body,
administrative or regulatory agency, arbitrator or other governmental
authority.

        (e)  The Company shall at all times maintain its books of
account and records relating to the Collateral at its principal place
of business and its Collateral at the locations set forth on Schedule
A attached hereto and may not relocate such books of account and
records or tangible Collateral unless it delivers to the Secured
Party at least 30 days prior to such relocation (i) written notice of
such relocation and the new location thereof (which must be within
the United States) and (ii) evidence that appropriate financing
statements and other necessary documents have been filed and recorded
and other steps have been taken to perfect the Security Interest to
create in favor of the Secured Party valid, perfected and continuing
first priority liens in the Collateral.

        (f)  This Agreement creates in favor of the Secured Party a
valid security interest in the Collateral securing the payment and
performance of the Obligations and, upon making the filings described
in the immediately following sentence, a perfected first priority
security interest in such Collateral.  Except for the filing of
financing statements on Form-1 under the UCC with the jurisdictions
indicated on Schedule B, attached hereto, no authorization or
approval of or filing with or notice to any governmental authority or
regulatory body is required either (i) for the grant by the Company
of, or the effectiveness of, the Security Interest granted hereby or
for the execution, delivery and performance of this Agreement by the
Company or (ii) for the perfection of or exercise by the Secured
Party of its rights and remedies hereunder.

        (g)  On the date of execution of this Agreement, the
Company will deliver to the Secured Party one or more executed UCC
financing statements on Form-1 with respect to the Security Interest
for filing with  the jurisdictions indicated on Schedule B, attached
hereto and in such other jurisdictions as may be requested by the
Secured Party.

        (h)  The execution, delivery and performance of this
Agreement does not conflict with or cause a breach or default, or an
event that with or without the passage of time or notice, shall
constitute a breach or default, under any agreement to which the
Company is a party or by which the Company is bound.  No consent
(including, without limitation, from stock holders or creditors of
the Company) is required for the Company to enter into and perform
its obligations hereunder.

        (i)  The Company shall at all times maintain the liens and
Security Interest provided for hereunder as valid and perfected first
priority liens and security interests in the Collateral in favor of
the Secured Party until this Agreement and the Security Interest
hereunder shall terminate pursuant to Section 11.  The Company hereby
agrees to defend the same against any and all persons.  The Company
shall safeguard and protect all Collateral for the account of the
Secured Party.  At the request of the Secured Party, the Company will
sign and deliver to the Secured Party at any time or from time to
time one or more financing statements pursuant to the UCC (or any
other applicable statute) in form reasonably satisfactory to the
Secured Party and will pay the cost of filing the same in all public
offices wherever filing is, or is deemed by the Secured Party to be,
necessary or desirable to effect the rights and obligations provided
for herein. Without limiting the generality of the foregoing, the
Company shall pay all fees, taxes and other amounts necessary to
maintain the Collateral and the Security Interest hereunder, and the
Company shall obtain and furnish to the Secured Party from time to
time, upon demand, such releases and/or subordinations of claims and
liens which may be required to maintain the priority of the Security
Interest hereunder.

        (j)  The Company will not transfer, pledge, hypothecate,
encumber, license (except for non-exclusive licenses granted by the
Company in the ordinary course of business), sell or otherwise
dispose of any of the Collateral without the prior written consent of
the Secured Party.

        (k)  The Company shall keep and preserve its Equipment,
Inventory and other tangible Collateral in good condition, repair and
order and shall not operate or locate any such Collateral (or cause
to be operated or located) in any area excluded from insurance
coverage.

        (l)  The Company shall, within ten (10) days of obtaining
knowledge thereof, advise the Secured Party promptly, in sufficient
detail, of any substantial change in the Collateral, and of the
occurrence of any event which would have a material adverse effect on
the value of the Collateral or on the Secured Party's security
interest therein.

        (m)  The Company shall promptly execute and deliver to the
Secured Party such further deeds, mortgages, assignments, security
agreements, financing statements or other instruments, documents,
certificates and assurances and take such further action as the
Secured Party may from time to time request and may in its sole
discretion deem necessary to perfect, protect or enforce its security
interest in the Collateral including, without limitation, the
execution and delivery of a separate security agreement with respect
to the Company's intellectual property ("Intellectual Property
Security Agreement") in which the Secured Party has been granted a
security interest hereunder, substantially in a form acceptable to
the Secured Party, which Intellectual Property Security Agreement,
other than as stated therein, shall be subject to all of the terms
and conditions hereof.

        (n)  The Company shall permit the Secured Party and its
representatives and agents to inspect the Collateral at any time, and
to make copies of records pertaining to the Collateral as may be
requested by the Secured Party from time to time.

        (o)  The Company will take all steps reasonably necessary
to diligently pursue and seek to preserve, enforce and collect any
rights, claims, causes of action and accounts receivable in respect
of the Collateral.

        (p)  The Company shall promptly notify the Secured Party in
sufficient detail upon becoming aware of any  attachment,
garnishment, execution or other legal process levied against any
Collateral and of any other information received by the Company that
may materially affect the value of the Collateral, the Security
Interest or the rights and remedies of the Secured Party hereunder.

        (q)  All information heretofore, herein or hereafter
supplied to the Secured Party by or on behalf of the Company with
respect to the Collateral is accurate and complete in all material
respects as of the date furnished.

        (r)  Schedule A attached hereto contains a list of all of
the subsidiaries of Company.

     4.  Defaults.  The following events shall be "Events of
Default":

        (a)  The occurrence of an Event of Default (as defined in
the Notes) under the Notes;

        (b)  Any representation or warranty of the Company in this
Agreement or in the Intellectual Property Security Agreement shall
prove to have been incorrect in any material respect when made;

        (c)  The failure by the Company to observe or perform any
of its obligations hereunder or in the Intellectual Property Security
Agreement for ten (10) days after receipt by the Company of notice of
such failure from the Secured Party; and

        (d)  Any breach of, or default under, the Warrants.

     5.  Duty To Hold In Trust.  Upon the occurrence of any Event of
Default and at any time thereafter, the Company shall, upon receipt
by it of any revenue, income or other sums subject to the Security
Interest, whether payable pursuant to the Notes or otherwise, or of
any check, draft, note, trade acceptance or other instrument
evidencing an obligation to pay any such sum, hold the same in trust
for the Secured Party and shall forthwith endorse and transfer any
such sums or instruments, or both, to the Secured Party for
application to the satisfaction of the Obligations.

     6.  Rights and Remedies Upon Default.  Upon occurrence of any
Event of Default and at any time thereafter, the Secured Party shall
have the right to exercise all of the remedies conferred hereunder
and under the Notes, and the Secured Party shall have all the rights
and remedies of a secured party under the UCC and/or any other
applicable law (including the Uniform Commercial Code of any
jurisdiction in which any Collateral is then located).  Without
limitation, the Secured Party shall have the following rights and
powers:

        (a)  The Secured Party shall have the right to take
possession of the Collateral and, for that purpose, enter, with the
aid and assistance of any person, any premises where the Collateral,
or any part thereof, is or may be placed and remove the same, and the
Company shall assemble the Collateral and make it available to the
Secured Party at places which the Secured Party shall reasonably
select, whether at the Company's premises or elsewhere, and make
available to the Secured Party, without rent, all of the Company's
respective premises and facilities for the purpose of the Secured
Party taking possession of, removing or putting the Collateral in
saleable or disposable form.

        (b)  The Secured Party shall have the right to operate the
business of the Company using the Collateral and shall have the right
to assign, sell, lease or otherwise dispose of and deliver all or any
part of the Collateral, at public or private sale or otherwise,
either with or without special conditions or stipulations, for cash
or on credit or for future delivery, in such parcel or parcels and at
such time or times and at such place or places, and upon such terms
and conditions as the Secured Party may deem commercially reasonable,
all without (except as shall be required by applicable statute and
cannot be waived) advertisement or demand upon or notice to the
Company or right of redemption of the Company, which are hereby
expressly waived.  Upon each such sale, lease, assignment or other
transfer of Collateral, the Secured Party may, unless prohibited by
applicable law which cannot be waived, purchase all or any part of
the Collateral being sold, free from and discharged of all trusts,
claims, right of redemption and equities of the Company, which are
hereby waived and released.

     7.  Applications of Proceeds.  The proceeds of any such sale,
lease or other disposition of the Collateral hereunder shall be
applied first, to the expenses of retaking, holding, storing,
processing and preparing for sale, selling, and the like (including,
without limitation, any taxes, fees and other costs incurred in
connection therewith) of the Collateral, to the reasonable attorneys'
fees and expenses incurred by the Secured Party in enforcing its
rights hereunder and in connection with collecting, storing and
disposing of the Collateral, and then to satisfaction of the
Obligations, and to the payment of any other amounts required by
applicable law, after which the Secured Party shall pay to the
Company any surplus proceeds.  If, upon the sale, license or other
disposition of the Collateral, the proceeds thereof are insufficient
to pay all amounts to which the Secured Party is legally entitled,
the Company will be liable for the deficiency, together with interest
thereon, at the rate of 15% per annum (the "Default Rate"), and the
reasonable fees of any attorneys employed by the Secured Party to
collect such deficiency.  To the extent permitted by applicable law,
the Company waives all claims, damages and demands against the
Secured Party arising out of the repossession, removal, retention or
sale of the Collateral, unless due to the gross negligence or willful
misconduct of the Secured Party.

     8.  Costs and Expenses.  The Company agrees to pay all out-of-
pocket fees, costs and expenses incurred in connection with any
filing required hereunder, including without limitation, any
financing statements, continuation statements, partial releases
and/or termination statements related thereto or any expenses of any
searches reasonably required by the Secured Party.  The Company shall
also pay all other claims and charges which in the reasonable opinion
of the Secured Party might prejudice, imperil or otherwise affect the
Collateral or the Security Interest therein.  The Company will also,
upon demand, pay to the Secured Party the amount of any and all
reasonable expenses, including the reasonable fees and expenses of
its counsel and of any experts and agents, which the Secured Party
may incur in connection with (i) the enforcement of this Agreement,
(ii) the custody or preservation of, or the sale of, collection from,
or other realization upon, any of the Collateral, or (iii) the
exercise or enforcement of any of the rights of the Secured Party
under the Notes.  Until so paid, any fees payable hereunder shall be
added to the principal amount of the Notes and shall bear interest at
the Default Rate.

     9.  Responsibility for Collateral.  The Company assumes all
liabilities and responsibility in connection with all Collateral, and
the obligations of the Company hereunder or under the Notes and the
Warrants shall in no way be affected or diminished by reason of the
loss, destruction, damage or theft of any of the Collateral or its
unavailability for any reason.

     10.  Security Interest Absolute.  All rights of the Secured
Party and all Obligations of the Company hereunder, shall be absolute
and unconditional, irrespective of: (a) any lack of validity or
enforceability of this Agreement, the Notes, the Warrants or any
agreement entered into in connection with the foregoing, or any
portion hereof or thereof; (b) any change in the time, manner or
place of payment or performance of, or in any other term of, all or
any of the Obligations, or any other amendment or waiver of or any
consent to any departure from the Notes, the Warrants or any other
agreement entered into in connection with the foregoing; (c)  any
exchange, release or nonperfection of any of the Collateral, or any
release or amendment or waiver of or consent to departure from any
other collateral for, or any guaranty, or any other security, for all
or any of the Obligations; (d) any action by the Secured Party to
obtain, adjust, settle and cancel in its sole discretion any
insurance claims or matters made or arising in connection with the
Collateral; or (e) any other circumstance which might otherwise
constitute any legal or equitable defense available to the Company,
or a discharge of all or any part of the Security Interest granted
hereby.  Until the Obligations shall have been paid and performed in
full, the rights of the Secured Party shall continue even if the
Obligations are barred for any reason, including, without limitation,
the running of the statute of limitations or bankruptcy.  The Company
expressly waives presentment, protest, notice of protest, demand,
notice of nonpayment and demand for performance.  In the event that
at any time any transfer of any Collateral or any payment received by
the Secured Party hereunder shall be deemed by final order of a court
of competent jurisdiction to have been a voidable preference or
fraudulent conveyance under the bankruptcy or insolvency laws of the
United States, or shall be deemed to be otherwise due to any party
other than the Secured Party, then, in any such event, the Company's
obligations hereunder shall survive cancellation of this Agreement,
and shall not be discharged or satisfied by any prior payment thereof
and/or cancellation of this Agreement, but shall remain a valid and
binding obligation enforceable in accordance with the terms and
provisions hereof.  The Company waives all right to require the
Secured Party to proceed against any other person or to apply any
Collateral which the Secured Party may hold at any time, or to
marshal assets, or to pursue any other remedy.  The Company waives
any defense arising by reason of the application of the statute of
limitations to any obligation secured hereby.

     11.  Term of Agreement.  This Agreement and the Security
Interest shall terminate on the date on which all payments under the
Notes have been made in full and all other Obligations have been paid
or discharged.  Upon such termination, the Secured Party, at the
request and at the expense of the Company, will join in executing any
termination statement with respect to any financing statement
executed and filed pursuant to this Agreement.

     12.  Power of Attorney; Further Assurances.

        (a)  The Company authorizes the Secured Party, and does
hereby make, constitute and appoint it, and its respective officers,
agents, successors or assigns with full power of substitution, as the
Company's true and lawful attorney-in-fact, with power, in its own
name or in the name of the Company, to, after the occurrence and
during the continuance of an Event of Default, (i) endorse any notes,
checks, drafts, money orders, or other instruments of payment
(including payments payable under or in respect of any policy of
insurance) in respect of the Collateral that may come into possession
of the Secured Party; (ii) to sign and endorse any UCC financing
statement or any invoice, freight or express bill, bill of lading,
storage or warehouse receipts, drafts against debtors, assignments,
verifications and notices in connection with accounts, and other
documents relating to the Collateral; (iii) to pay or discharge
taxes, liens, security interests or other encumbrances at any time
levied or placed on or threatened against the Collateral; (iv) to
demand, collect, receipt for, compromise, settle and sue for monies
due in respect of the Collateral; and (v) generally, to do, at the
option of the Secured Party, and at the Company's expense, at any
time, or from time to time, all acts and things which the Secured
Party deems necessary to protect, preserve and realize upon the
Collateral and the Security Interest granted therein in order to
effect the intent of this Agreement, the Notes and the Warrants, all
as fully and effectually as the Company might or could do; and the
Company hereby ratifies all that said attorney shall lawfully do or
cause to be done by virtue hereof.  This power of attorney is coupled
with an interest and shall be irrevocable for the term of this
Agreement and thereafter as long as any of the Obligations shall be
outstanding.

        (b)  On a continuing basis, the Company will make, execute,
acknowledge, deliver, file and record, as the case may be, in the
proper filing and recording places in any jurisdiction, including,
without limitation, the jurisdictions indicated on Schedule B,
attached hereto, all such instruments, and take all such action as
may reasonably be deemed necessary or advisable, or as reasonably
requested by the Secured Party, to perfect the Security Interest
granted hereunder and otherwise to carry out the intent and purposes
of this Agreement, or for assuring and confirming to the Secured
Party the grant or perfection of a security interest in all the
Collateral.

        (c)  The Company hereby irrevocably appoints the Secured
Party as the Company's attorney-in-fact, with full authority in the
place and stead of the Company and in the name of the Company, from
time to time in the Secured Party's discretion, to take any action
and to execute any instrument which the Secured Party may deem
necessary or advisable to accomplish the purposes of this Agreement,
including the filing, in its sole discretion, of one or more
financing or continuation statements and amendments thereto, relative
to any of the Collateral without the signature of the Company where
permitted by law.

     13.  Notices.  All notices, requests, demands and other
communications hereunder shall be in writing, with copies to all the
other parties hereto, and shall be deemed to have been duly given

     14.  Other Security.  To the extent that the Obligations are now
or hereafter secured by property other than the Collateral or by the
guarantee, endorsement or property of any other person, firm,
corporation or other entity, then the Secured Party shall have the
right, in its sole discretion, to pursue, relinquish, subordinate,
modify or take any other action with respect thereto, without in any
way modifying or affecting any of the Secured Party's rights and
remedies hereunder.

     15.  Miscellaneous.

        (a)  No course of dealing between the Company and the
Secured Party, nor any failure to exercise, nor any delay in
exercising, on the part of the Secured Party, any right, power or
privilege hereunder or under the Notes shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, power
or privilege hereunder or thereunder preclude any other or further
exercise thereof or the exercise of any other right, power or privilege.

        (b)  All of the rights and remedies of the Secured Party
with respect to the Collateral, whether established hereby or by the
Notes or by any other agreements, instruments or documents or by law
shall be cumulative and may be exercised singly or concurrently.

        (c)  This Agreement constitutes the entire agreement of the
parties with respect to the subject matter hereof and is intended to
supersede all prior negotiations, understandings and agreements with
respect thereto.  Except as specifically set forth in this Agreement,
no provision of this Agreement may be modified or amended except by a
written agreement specifically referring to this Agreement and signed
by the parties hereto.

        (d)  In the event that any provision of this Agreement is
held to be invalid, prohibited or unenforceable in any jurisdiction
for any reason, unless such provision is narrowed by judicial
construction, this Agreement shall, as to such jurisdiction, be
construed as if such invalid, prohibited or unenforceable provision
had been more narrowly drawn so as not to be invalid, prohibited or
unenforceable.  If, notwithstanding the foregoing, any provision of
this Agreement is held to be invalid, prohibited or unenforceable in
any jurisdiction, such provision, as to such jurisdiction, shall be
ineffective to the extent of such invalidity, prohibition or
unenforceability without invalidating the remaining portion of such
provision or the other provisions of this Agreement and without
affecting the validity or enforceability of such provision or the
other provisions of this Agreement in any other jurisdiction.

        (e)  No waiver of any breach or default or any right under
this Agreement shall be considered valid unless in writing and signed
by the party giving such waiver, and no such waiver shall be deemed a
waiver of any subsequent breach or default or right, whether of the
same or similar nature or otherwise.

        (f)  This Agreement shall be binding upon and inure to the
benefit of each party hereto and its successors and assigns.

        (g)  Each party shall take such further action and execute
and deliver such further documents as may be necessary or appropriate
in order to carry out the provisions and purposes of this Agreement.

        (h)  This Agreement shall be construed in accordance with
the laws of the State of New York, except to the extent the validity,
perfection or enforcement of a security interest hereunder in respect
of any particular Collateral which are governed by a jurisdiction
other than the State of New York in which case such law shall govern.
Each of the parties hereto irrevocably submit to the exclusive
jurisdiction of any New York State or United States Federal court
sitting in Manhattan county over any action or proceeding arising out
of or relating to this Agreement, and the parties hereto hereby
irrevocably agree that all claims in respect of such action or
proceeding may be heard and determined in such New York State or
Federal court.  The parties hereto agree that a final judgment in any
such action or proceeding shall be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other manner
provided by law.  The parties hereto further waive any objection to
venue in the State of New York and any objection to an action or
proceeding in the State of New York on the basis of forum non
conveniens.

        (i)  EACH PARTY HERETO HEREBY AGREES TO WAIVE ITS
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING OUT OF THIS AGREEMENT.  THE SCOPE OF THIS
WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF ANY DISPUTES THAT MAY BE
FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATER OF THIS
AGREEMENT, INCLUDING WITHOUT LIMITATION CONTRACT CLAIMS, TORT CLAIMS,
BREACH OF DUTY CLAIMS AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS.
EACH PARTY HERETO ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL
INDUCEMENT FOR EACH PARTY TO ENTER INTO A BUSINESS RELATIONSHIP, THAT
EACH PARTY HAS ALREADY RELIED ON THIS WAIVER IN ENTERING INTO THIS
AGREEMENT AND THAT EACH PARTY WILL CONTINUE TO RELY ON THIS WAIVER IN
THEIR RELATED FUTURE DEALINGS. EACH PARTY FURTHER WARRANTS AND
REPRESENTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL,
AND THAT SUCH PARTY HAS KNOWINGLY AND VOLUNTARILY WAIVES ITS RIGHTS
TO A JURY TRIAL FOLLOWING SUCH CONSULTATION.  THIS WAIVER IS
IRREVOCABLE, MEANING THAT, NOTWITHSTANDING ANYTHING HEREIN TO THE
CONTRARY, IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND
THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS AND
SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.  IN THE EVENT OF A
LITIGATION, THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A
TRIAL BY THE COURT.

        (j)  This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an
original and, all of which taken together shall constitute one and
the same Agreement.  In the event that any signature is delivered by
facsimile transmission, such signature shall create a valid binding
obligation of the party executing (or on whose behalf such signature
is executed) the same with the same force and effect as if such
facsimile signature were the original thereof.
