                                                    July 26, 2002



Careside, Inc.
6100 Bristol Parkway
Culver City, CA 90230
Attention: Chief Executive Officer

Dear Careside, Inc.:

          The undersigned (the "Purchaser") desires to make an investment in
debt securities of Careside, Inc. (the "Company") and understands that the
Company is offering the private placement of its debt securities (the "Private
Placement"), each such security substantially in the form of the Investment Note
attached as Exhibit A-1 (each, an "Investment Note.") This letter agreement,
together with all exhibits hereto (the "Agreement") sets forth the terms and
conditions upon which the Purchaser will purchase an Investment Note. It is the
Company's intention that all investors in the Private Placement acquire their
Investment Notes under the terms and conditions of an agreement which is
substantially the same as this Agreement.

          In the Private Placement, the Company will issue not less than
$500,000 (the "Minimum Placement Amount") and not more than $5,000,000 (the
"Maximum Placement Amount") of Investment Notes. Investment Notes issued in the
Private Placement may be purchased by the Company's officers, directors,
employees and/or affiliates. Any person purchasing the Company's Investment
Notes in connection with the Private Placement must purchase at least $500,000
of Investment Notes, subject to the Company's decision to accept a lesser
investment. Each purchaser of an Investment Note will have an opportunity to
exchange such purchaser's Investment Note for a Convertible Note in the form of
Exhibit A-2 (each a "Convertible Note") with the same principal amount as the
Investment Note within fifteen (15) days after the Company obtains the Required
Approval (as defined below in this Agreement).

          If the Company issues the Maximum Placement Amount and all holders of
Investment Notes representing such Maximum Placement Amount exchange their
Investment Notes for Convertible Notes, the number of shares of the Company's
common stock, $.01 par value (the "Common Stock") issued upon conversion of the
Convertible Notes will equal ninety

Page 2

percent (90%) of the Company's outstanding Common Stock. If the Company issues
the Minimum Placement Amount and all holders of Investment Notes representing
such amount exchange their Investment Notes for Convertible Notes, the number of
shares of Common Stock issued upon conversion of the Convertible Notes will be
nine percent (9%) of the Company's outstanding Common Stock. The Private
Placement will terminate on August 30, 2002, and no additional Investment Notes
will be issued after such date, without the consent of a majority of the holders
of the then outstanding Investment Notes. In no event will the Maximum Placement
Amount be exceeded.

               Based on the foregoing, and in consideration of the mutual
covenants and representations contained herein, the receipt and sufficiency of
which are hereby acknowledged, and intending to be legally bound, the
undersigned Purchaser hereby acknowledges the foregoing and agrees to purchase
an Investment Note in the principal amount set forth at the Purchaser's
signature to this Agreement (the "Subscription Amount"). The undersigned and the
Company further agree as follows:

Section 1. Investment.

     1.1.   Investment Notes. On the date of this Agreement, the Company will
issue to the Purchaser an Investment Note having an original principal amount
equal to the Subscription Amount. The Investment Note will be in the form set
forth in Exhibit A-1 attached hereto.

     1.2.   Exchange of Notes; Required Approval; Proxy Solicitation.

               (a)  Upon receipt of Required Approval (as defined in
Section 1.2(c) below) and within fifteen (15) days after written notice of the
Approval Date (as defined in Section 1.2(c) below) is provided to the Purchaser
by the Company (the "Exchange Period"), the Purchaser may exchange the
Investment Note issued pursuant to Section 1.1 for a Convertible Note which
shall be in the form of Exhibit A-2 attached hereto and which shall have an
original principal amount equal to the outstanding principal amount of the
Purchaser's Investment Note.

               (b)  The Purchaser shall exercise such right to exchange by
providing the Company with written notice of the exchange prior to expiration of
the Ex change Period. Such notice shall be accompanied by surrender of the
Investment Note to the Company. The Company shall thereupon issue to the
Purchaser a Convertible Note and immediately cancel the Investment Note
surrendered by the Purchaser. Any accrued and unpaid interest owing under the
Investment Note at the time of such exchange shall remain an obligation of the
Company. In no event shall the Purchaser surrender an Investment Note evidencing
less than the full outstanding principal amount of such Investment Note. If the
Purchaser does not exchange the Purchaser's

<PAGE>

W. Vickery Stoughton
__________, 2002
Page 3

Investment Note for a Convertible Note during the Exchange Period, then the
Purchaser shall have no further right to exchange the Investment Note for a
Convertible Note.

          (c)   Promptly after sale of the Minimum Placement Amount, the Company
will take all action in accordance with applicable law, its certificate of
incorporation and by-laws, to convene a meeting of its stockholders (the
"Stockholders Meeting") as soon as reasonably practicable in order that its
stockholders may consider and vote upon the following:

                    (i)   the issuance of the Convertible Notes,

                    (ii)  an amendment to the Company's certificate of
incorporation to effect a reverse stock split of one (1) share of Common Stock
for every ten (10) shares of Common Stock currently outstanding or issuable
(1-for-10); and

                    (iii) an amendment to the Company's certificate of
incorporation to increase the post-split authorized number of shares of Common
Stock to fifty million (50,000,000).

          (d)   As soon as practicable, the Company shall, in cooperation with
the Purchaser and the other purchasers of Investment Notes in the Private
Placement, prepare and file with the Securities and Exchange Commission (the
"SEC"), preliminary proxy materials in order to enable the Company's
stockholders to consider and vote upon at the Stockholders Meeting the foregoing
matters (such proxy statement and any amendments or supplements thereto, the
"Proxy Statement"). The record date for those stockholders of the Company
entitled to vote at the Stockholders Meeting shall be after the Initial Closing
Date (defined below).

          (e)   For purposes of this Agreement, "Required Approval" means the
approval by the holders of a majority of the outstanding Common Stock of the
matters set forth in clauses (i) through (iii) of clause (c) above. The date on
which Required Approval is obtained is the "Approval Date."

     1.3. Registration Rights. The shares of Common Stock issued upon conversion
of any Convertible Notes shall be registered on a registration statement filed
within 45 days following the Approval Date, in accordance with the registration
rights set forth on Exhibit B hereto.

     Section 2. Closing.

     The purchase and issuance of the Investment Note to the undersigned
Purchaser shall occur on the date hereof, assuming the Minimum Placement Amount
has been raised. At such closing, Purchaser shall deliver to the Company: (i) a
copy of this Agreement duly executed by

<PAGE>

Page 4

Purchaser, (ii) immediately available funds in the amount of the Subscription
Amount, which is the principal amount of Purchaser's Investment Note, and (iii)
such other documents as the Company may reasonably require; and, the Company
shall deliver to Purchaser: (i) a copy of this Agreement duly executed by the
Company, (ii) the Investment Note in the principal amount of the Subscription
Amount and (iii) and such other documents as the Purchaser may reasonably
require.

Section 3. Representations, Warranties and Covenants.

     3.1. Company Representations, Warranties and Covenants. The Company
represents and warrants that:

           (a)  The Company is a corporation duly organized and validly existing
and in good standing under the laws of the State of Delaware, and duly qualified
to do business and in good standing as a foreign corporation in each state in
which the nature of its business or properties requires such qualification
(except where failure to qualify would not have a material adverse effect on the
Company taken as a whole), with full power and authority, corporate and
otherwise, to enter into and perform this Agreement, and to execute and deliver
the various instruments and documents provided for herein.

           (b)  The execution, delivery and performance by the Company of this
Agreement and the issuance and delivery by the Company of the Investment Note
and the Convertible Note, if any, as contemplated hereby have been duly
authorized by all necessary corporate action and will not violate any provision
of law, court order or decree, or any provision of the Company's certificate of
incorporation or bylaws, or result in the breach of, constitute a default under
or result in the creation of any lien, charge or encumbrance upon any property
or assets of the Company pursuant to any agreement or instrument to which the
Company is a party, or by which it or any of its property may be bound or
affected. This Agreement is a valid and binding obligation of the Company,
enforceable in accordance with its terms subject to general principles of equity
and bankruptcy and other laws affecting creditors' rights generally.

           (c)  While the Company is subject to lawsuits in each instance less
than $30,000 and in the aggregate less than $100,000, there are no material
lawsuits or proceedings pending, or, to the Company's knowledge, threatened,
against or affecting the Company and there are no proceedings before any
governmental commission, bureau or other administrative agency pending, or, to
the Company's knowledge, threatened, against or affecting the Company.

           (d)  As of March 31, 2002, the authorized capital stock of the
Company consisted of 50,000,000 shares of common stock, $.01 par value per share
and 5,000,000 shares

<PAGE>

W. Vickery Stoughton
__________, 2002
Page 5

of preferred stock, $.01 par value per share. As of March 31, 2002, there were
19,066,336 shares of Common Stock outstanding and 14,735,738 shares of Common
Stock issuable upon the exercise of outstanding warrants and options, all of
which are currently exercisable. The conversion of the Convertible Notes will
trigger customary anti-dilution adjustments in certain of the Company's
outstanding warrants which will depend on the number of Convertible Notes
issued.

           (e)  When, the Common Stock issuable upon conversion of any
Convertible Notes ("Conversion Shares") are issued, they will be duly
authorized, validly issued, fully paid and nonassessable. Conversion Shares will
be issued in reliance upon applicable exemptions from the registration and
qualification provisions of all applicable securities laws of the United States
and each state whose securities laws may be applicable thereto. All Common Stock
issued upon conversion of any Convertible Note will be issued free and clear of
any preemptive or similar right and free and clear of any claim, lien, security
interest or other encumbrance. Immediately following the Approval Date, the
Company will reserve for issuance upon conversion of any Convertible Note the
full number of shares of Common Stock issuable upon conversion thereof.

           (f)  No governmental permit, consent, approval or authorization is
required in connection with (i) the execution, delivery and performance of this
Agreement by the Company or (ii) the offer, sale, issuance and delivery by the
Company of the Convertible Notes or the Conversion Shares contemplated hereby;
provided that, all representations made to the Company by the Purchaser in this
Agreement and in any other written document or instrument delivered in
connection herewith are assumed for purposes of this representation and warranty
to be accurate and complete.

           (g)  As of the date hereof, shares of the Company's Common Stock,
shares, and its publicly traded warrants are traded on the American Stock
Exchange (AMEX).

           (h)  Neither the Company nor anyone acting on its behalf has effected
or will offer the Investment Notes or the Convertible Notes, if any, for
issuance or sale to, or solicit any offer to acquire the same from, anyone so as
to make the issuance and sale of such Investment Notes or Convertible Notes
subject to the registration requirements of Section 5 of the Securities Act of
1933, as amended (the "Securities Act").

           (i)  The transactions contemplated by this Agreement do not require
the approval, consent, authorization or act of, or the making by the Company of
any declaration, filing or registration with, any person (including but not
limited to the stockholders of the Company) other than (i) the Required Approval
and (ii) the filing of a Form D with the

<PAGE>

W. Vickery Stoughton
_________,2002
Page 6

Securities and Exchange Commission, the filing, pursuant to the registration
obligations set forth in Exhibit B hereto of a Form S-3 (or comparable
registration form), and applicable blue sky filings.

          (j) The Company owns (or possesses adequate and enforceable licenses
or other rights to use) all trademarks, trade names, copyrights, patents,
inventions, processes, source code, software and other technical know-how and
other proprietary rights now used in its business (the "Intellectual Property")
and to the Company's knowledge, has not infringed and is not infringing on the
trademarks, trade names, copyrights, patents, inventions, processes or other
technical know-how or other proprietary rights of any other person. Such
Intellectual Property is free of all claims, liens or encumbrances. No
proceedings have been instituted or are pending or, to the Company's knowledge,
threatened which challenge the validity of, or otherwise adversely affect the
ownership or use by the Company of such Intellectual Property. The Company has
no knowledge of the infringing use of any of such trademarks and trade names or
the infringement of any of such patents or copyrights by any other person.

          (k) The Company owns, holds or possesses all licenses, franchises,
permits, privileges, immunities, approvals and other authorizations from a
governmental body which are necessary to entitle it to own or lease, operate and
use the Company's assets and assets by the Company and to carry on and conduct
its business as conducted (herein collectively called "Governmental Permits")
except for such Governmental Permits as to which the failure to own, hold or
possess would not have a material adverse effect on the Company's assets, the
assets leased by the Company or the Company's business. The Company has
performed its material obligations under each Governmental Permit, and no event
has occurred or condition or state of facts exists which constitutes or, after
notice or lapse of time or both, would constitute a breach or default under any
such Governmental Permit or which permits after notice or lapse of time or both,
would permit revocation or termination of any such Governmental Permit, or which
might adversely affect in any material respect the rights of the Company under
any such Governmental Permits. No notice of cancellation, of default or of any
dispute concerning any Governmental Permit, or of any events, condition or state
of facts described in the preceding sentence, has been received by, or is known
to, the Company. Each Governmental Permit is valid, subsisting and in full force
and effect and will not be rendered invalid or lose its force and effect as a
result of the consummation of the transactions contemplated hereby, in each case
without (x) the occurrence of any breach, default or forfeiture of rights
thereunder, or (y) the consent, approval or act of, or the making of any filing
with, any governmental body.

          (l) Subsequent to the respective dates as of which information is
given in the Company's most recent quarterly report filed on Form 10-K with the
SEC, there has been no material and adverse change in the condition (financial
or otherwise) in the business, prospects,

<PAGE>

net worth or results of operations of the Company except (i) as announced by the
Company in its press releases on February 26, 2002 and April 1, 2002, and (ii)
the Company's workforce reductions undertaken in March and April 2002 and (iii)
as evidenced by the Company's need to undertake the transactions contemplated by
this Agreement.

          (m) The Company has filed all forms, reports and documents required to
be filed by it with the SEC, and has made available to the Purchaser all
registration statements (on all forms applicable to the registration of
securities), periodic reports and other documents filed by the Company with the
SEC, including all exhibits filed in connection therewith, and prior to the date
of this Agreement. As of their respective dates, such filings (i) complied in
all material respects with the requirements of the Securities Act of 1933 and
the Securities Exchange Act of 1934, and (ii) did not contain any untrue
statement of a material fact to omit to state a material fact required to be
stated therein or necessary in order to make the statements made therein, in the
light of the circumstances under which they were made, not misleading.

          (n) To the Company's knowledge, neither the Company nor any of their
respective directors, officers or controlling persons has, with respect to the
Company (i) taken, failed to take or will take, directly or indirectly, any
action resulting in a violation of Rule l0b-5 under the Securities Exchange Act
of 1934, as amended (the "1934 Act"), or designated to cause or result under the
Act or otherwise, in, or which has constituted or which reasonably might be
expected to constitute a device, scheme of artifice designed to defraud any
person, in connection with the purchase or sale of the Company's securities
(including, but not limited to, the Securities); (ii) made any untrue statement
of material fact or failed to state a material fact necessary in order to make
the statements made, in light of the circumstances under which they were made,
not misleading; or (iii) engaged in any act, practice, or course of business
which operates or would operate as a fraud or deceit upon any person, in
connection with the purchase or sale of a security (including, but not limited
to, the Conversion Shares).

          (o) The proceeds from the Private Placement will be used for the
following purposes: (i) repayment of a bridge loan in the amount of $350,000
owed to Crestview Capital Fund, L.P., pursuant to that certain Note and Warrant
Purchase Agreement dated as of February 28, 2002, (ii) payment of accrued
payroll and other accrued liabilities, and (iii) working capital.

          (p) Following the Required Approval and the Exchange Period, the
Company shall take all steps necessary to list for trading on AMEX a sufficient
number of shares of Common Stock to enable the conversion of all Convertible
Notes.

          (q) As security for the repayment of all liabilities arising under the
Investment Notes or Convertible Notes, the Company hereby grants to Purchaser,
and the other purchasers in

<PAGE>

Page 8

the Private Placement, a security interest in and lien on all of its assets,
including without limitation its patents and trademarks, and all accessions,
additions, attachments, substitutions, proceeds, profits and products thereof,
whether now or hereafter existing. Holder shall have all rights provided to a
secured party under the Intellectual Property Security Agreement, substantially
in the form attached as Exhibit C hereto, which shall be executed by the
Company, dated the date hereof and delivered to the Purchaser, and under the
Uniform Commercial Code of the State of Delaware. The Company shall execute and
deliver such documentation as Holder may reasonably request to evidence and
perfect Holder's security interest granted in this clause (q). Promptly after
the closing of the offering period for the Private Placement, the Company shall
file an executed Notice of Intellectual Property Security Agreement attached to
the Intellectual Property Security Agreement which is attached hereto as Exhibit
C with the appropriate office and provide proof of filing to Purchaser and the
other purchasers of Investment Notes in the Private Placement. Such Notice shall
indicate that all such purchasers have a security interest in the Company's
intellectual property. The Company shall not grant any other security interest
in its intellectual property prior to the filing of such Notice. Notwithstanding
the foregoing, the lien created by the Intellectual Property Security Agreement
shall be subordinate to a lien in favor of the lenders in the financing
evidenced in the letter of intent received by the Company from Sextant Funding,
LLC dated March 2002.

     3.2. Purchaser Representations, Warranties and Covenants. The Purchaser
hereby acknowledges, represents and warrants to, and agrees with, the Company
and its affiliates as follows:

          (a) The Purchaser is acquiring the Investment Note and, if applicable,
the Conversion Note and Conversion Shares for the Purchaser's own account as
principal, not as a nominee or agent, for investment purposes only, and not with
a view to, or for, resale, distribution or fractionalization thereof in whole or
in part, which resale, distribution or fractionalization would violate the
Securities Act. Further, the Purchaser does not have any contract, undertaking,
agreement or arrangement with any person to sell, transfer or grant
participations to such person or to any third person, with respect to the
Investment Note, Convertible Note, or Conversion Shares, if any.

          (b) The Purchaser has full power and authority to enter into this
Agreement. The execution and delivery of this Agreement has been duly authorized
by the Purchaser and this Agreement constitutes a valid and legally binding
obligation of the Purchaser.

          (c) The Purchaser acknowledges the Purchaser's understanding that the
issuance of the Investment Note and Convertible Note or Conversion Shares, if
any, is intended to be exempt from registration under the Securities Act by
virtue of Section 4(2) thereof and the

<PAGE>

W. Vickery Stoughton
_________,2002
Page 9

provisions of Regulation D promulgated thereunder ("Regulation D"). In
furtherance thereof, the Purchaser represents and warrants to and agrees with
the Company that the Purchaser has the financial ability to bear the economic
risk of the Purchaser's investment, has adequate means for providing for the
Purchaser's current needs and personal contingencies and has no need for
liquidity with respect to the Purchaser's investment in the Company.

          (d) The Purchaser is an "accredited investor," as that term is defined
in Rule 501 of Regulation D as described in Appendix1 hereto.

          (e) The Purchaser acknowledges that it currently has such knowledge
and experience in financial and business matters that it is capable of
evaluating the merits and risks of this investment and further acknowledges that
it is able to bear the economic risk of this investment. During the course of
this transaction, the Purchaser acknowledges that it has had the opportunity to
ask questions of, and receive answers from, management of the Company concerning
the terms and conditions of this investment and obtain any additional
information of the same kind that is specified in Rule 501 of Regulation D of
the Securities Act, or that is necessary to verify the accuracy of the other
information obtained. The Purchaser acknowledges that it has received such
information as it deems necessary to enable it to make its investment decision.

          (f) The Purchaser further represents, warrants and agrees that the
Purchaser will not sell or otherwise transfer the Investment Note or Convertible
Note or Conversion Shares, if any, without registration under the Securities Act
or an exemption therefrom, and that the Purchaser fully understands and agrees
that the Purchaser must bear the economic risk of the Purchaser's purchase
because, among other reasons, neither of the Investment Note or Convertible Note
or Conversion Shares, if any, has been registered under the Securities Act or
under the securities laws of any state and, therefore, none can be resold,
pledged, assigned or otherwise disposed of unless they are subsequently
registered under the Securities Act and under the applicable securities laws of
such states or an exemption from such registration is available. In particular,
the Purchaser is aware that the Conversion Shares will be "restricted
securities," as such term is defined in Rule 144 promulgated under the
Securities Act ("Rule 144"), and may not be sold pursuant to Rule 144 unless all
of the conditions of Rule 144 are met. The Purchaser also understands that,
except as expressly otherwise provided in this Agreement, the Company is under
no obligation to register the Conversion Shares on the Purchaser's behalf or to
assist the Purchaser in complying with any exemption from registration under the
Securities Act or applicable state securities laws. The Purchaser further
understands that sales or transfers of the Investment Note and Convertible Note
or Conversion Shares, if any, are further restricted by state securities laws
and the provisions of this Agreement.

          (g) No representations or warranties have been made to the Purchaser
by the Company, or any officer, employee, agent or affiliate of the Company,
other than the representations and warranties of the Company contained herein,
and in purchasing the Investment Note and Convertible Note, if any, the
Purchaser is not relying upon any representations other than those contained
herein.

          (h) Any information which the Purchaser has heretofore furnished to
the Company in writing with respect to the Purchaser's financial position and
business experience is correct and complete in all material respects as of the
date of this Agreement and if there should be any material change in such
information the Purchaser will immediately furnish such revised or corrected
information to the Company.

          (i) The Purchaser understands and agrees that, at issuance, Conversion
Shares shall bear the following legend, or a similar legend to the same effect,
until (i) such Common Stock shall have been registered under the Securities Act
and effectively been disposed of in accordance with a registration statement
that has been declared effective; or (ii) in the opinion of counsel for the
Company such Common Stock may be sold without registration under the Securities
Act or any applicable "Blue Sky" or state securities laws:

          "THE COMMON STOCK REPRESENTED BY THIS CERTIFICATE
          HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT
          OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND
          IS SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AS
          SET FORTH IN THIS CERTIFICATE. THE COMMON STOCK
          REPRESENTED HEREBY MAY NOT BE SOLD, TRANSFERRED,
          OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN
          EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR
          AN OPINION OF COUNSEL, REASONABLY ACCEPTABLE TO
          COUNSEL FOR THE COMPANY, TO THE EFFECT THAT THE
          PROPOSED SALE, TRANSFER, OR DISPOSITION MAY BE
          EFFECTUATED WITHOUT REGISTRATION UNDER THE ACT."

COMMON STOCK ISSUABLE UPON CONVERSION OF THIS NOTE HAVE BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND NEITHER MAY BE OFFERED,
SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL

COUNSEL OR OTHER EVIDENCE REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH
REGISTRATION IS NOT REQUIRED.

THIS NOTE IS SUBJECT TO THE TERMS AND PROVISIONS OF AN INVESTMENT LETTER
AGREEMENT, DATED AS OF THE DATE HEREOF BY AND BETWEEN CARESIDE, INC. AND THE
HOLDER NAMED BELOW.

                            CONVERTIBLE SECURED NOTE

$________                                                    _____________, 2002

          FOR VALUE RECEIVED, CARESIDE, INC., a Delaware corporation with
offices at 6100 Bristol Parkway, Culver City, California 90230 (the "Company")
promises to pay to the order of _______________________, (the "Holder"), or to
such other person or at such other place as the Holder may designate from time
to time in writing, the outstanding amount of ________________________________
Dollars ($_____________) in lawful money of the United States of America. This
Convertible Secured Note (this "Note") is issued pursuant to a letter agreement
between the Company and the Holder dated the date hereof (the "Letter
Agreement"). All capitalized terms used herein but not otherwise defined herein
shall have the meanings ascribed to them in the Letter Agreement.

          1. Maturity. The amount outstanding under this Note will be due and
payable on July 1, 2003 (the "Maturity Date"). The Company may prepay this Note
at any time without penalty or premium.

          2. Interest. Interest shall accrue at an interest rate of ten percent

                                      A2-1

<PAGE>

          3. Conversion.

               (a) Optional Conversion. All principal and accrued interest owing
under this Note will be convertible at the option of the Holder, at any time
after July 1, 2002 and until such time as this Note is fully repaid, into a
number of shares (the "Conversion Shares") of common stock of the Company, par
value $.01 per share (the "Common Stock"), equal to the product of

                      (i)  17,159,702 (being that number of shares of Common
Stock which represents ninety percent (90%) of the issued and outstanding Common
Stock of the Company after the reverse stock split contemplated by the Letter
Agreement),

          multiplied by

                      (ii) a fraction, the numerator of which is the outstanding
principal amount of this Note on the date the Conversion Notice (defined below)
is given and the denominator of which is Five Million Dollars ($5,000,000).

All obligations for repayment of outstanding principal and interest accrued
under this Note shall be extinguished upon such conversion.

               (b) Mandatory Conversion. In the event the closing market price
on the American Stock Exchange ("AMEX") of the common stock of the Company is
$5.00 or greater for ten (10) consecutive trading days after the date of
effectiveness of the Registration Statement (as defined in Exhibit B to the
Letter Agreement), this Note shall automatically convert into the Conversion
Shares. For purposes of this Note, "trading day" means a day on which AMEX or
such other national securities exchange is open for business.

               (c) Optional Conversion Procedure. In order to exercise the
conversion privilege set forth in Section 3.a above, Holder shall surrender this
Note and give written notice (the "Conversion Notice") to the Company of its
election so to convert this Note. Conversion shall be in whole and not in part.
Within five (5) business days after Holder gives the Conversion Notice, the
Company shall issue (or cause its transfer agent to issue), and deliver to
Holder a certificate or certificates for the Conversion Shares registered in the
name of Holder in accordance with the provisions of this Section 3.

          Each conversion shall be deemed to have been effected on the date on
which the Conversion Notice shall have been given, and Holder shall be deemed to
have become on said date the holder of record of the Conversion Shares.

          No fractional shares of Common Stock or scrip representing fractional
shares shall be issued upon conversion of this Note. If any fractional share of
Common Stock would be

                                      A2-2

<PAGE>

issuable upon the conversion of this Note, the Company shall make an adjustment
therefor in cash at the closing market price as reported on the AMEX at the
close of the trading day immediately preceding the date the Conversion Notice
is given.

               (d) In the event a reverse stock split other than that
contemplated by the Letter Agreement is, with appropriate approvals, effected,
or in the event of a subsequent recapitalization, reclassification, stock split,
reverse stock split or similar shifts in the capitalization of the Company
occurs, the number of Conversion Shares issuable upon conversion of this Note
shall be equitably adjusted.

          4. Security. As security for the repayment of all liabilities arising
under this Note (including amounts payable under Section 9 of this Note), the
Company hereby grants to Holder a security interest in and lien on all of its
assets, including without limitation its patents and trademarks, and all
accessions, additions, attachments, substitutions, proceeds, profits and
products thereof, whether now or hereafter existing. Holder shall have all
rights provided to a secured party under the Intellectual Property Security
Agreement, substantially in the form attached as Exhibit C to the Letter
Agreement, executed by the Company in favor of the Holder and dated the date
hereof, and under the Uniform Commercial Code of the State of Delaware. The
Company shall execute and deliver such documentation as Holder may reasonably
request to evidence and perfect Holder's security interest granted in this
Section 4.

          5. Events of Default. The occurrence of one or more of the following
events (after the expiration of any stated notice or cure period) shall
constitute an event of default ("Event of Default") hereunder and shall result
in the holder being deemed to have made a demand for payment:

               (a) The Company shall fail to make any payment due to the Holder
under this Note within ten (10) days after the same shall become due and
payable;

                                    EXHIBIT B

                   TERMS OF REGISTRATION OF CONVERSION SHARES

         1. Registration of the Common Stock.


               (a) Subject to paragraph 1(b) below, within forty-five (45) days
after the Approval Date, the Company will file a registration statement (the
"Registration Statement") on Form S-3 with the SEC registering for resale under
the Securities Act the Common Stock issuable upon conversion of the Convertible
Notes outstanding at the end of the Exchange Period. The Company reserves the
right to convert such registration to a registration with like effect on any
other form that may be or may become available to the Company with the
Purchaser's consent (not to be unreasonably withheld) and must register such
shares on a different form if Form S-3 is not then currently available. The
Company further reserves the right to include in such registration statement for
registration any shares of its Common Stock which the Company, in its sole
discretion, determines to include therein. In the event Purchaser does not elect
to exchange the Investment Note for a Convertible Note pursuant to Section 1.2
of the Agreement, the Company shall not have an obligation to file a
Registration Statement under this Section 1(a) above within the aforementioned
thirty (30) day period.

               (b) If the Company shall furnish to the holders of the
Convertible Notes and/or Common Stock issued upon conversion thereof (each a
"Holder" and collectively the "Holders") a certificate signed by its Chief
Executive Officer stating that, in the good faith judgment of the Company's
Board of Directors, it would be materially detrimental to the Company and its
shareholders for the Registration Statement to be filed by reason of a material
activity or pending event or transaction (such as a material acquisition, joint
venture, merger, consolidation or financing transaction) and it is therefore
advisable to defer the filing of such registration statement, the Company shall
have a one-time right to defer such filing of the Registration Statement for a
period of not more than ninety (90) days after the date upon which the Company
would otherwise have been required to file the Registration Statement pursuant
to Section 1(a). The Company hereby confirms that it is not aware of any event,
development, fact or state of affairs that exists as of the date hereof that
constitutes, or that would reasonably be expected to lead to, a material
activity or pending event or transaction within the meaning of the preceding
sentence. If registration is deferred pursuant to this subsection (b), the
Company shall diligently pursue such course of action as will allow it to resume
its registration obligations hereunder.

               (c) The Company's obligation to register shares of Common Stock
hereunder is limited to one Registration Statement which becomes effective under
the Securities Act, and, provided that the Company complies with its obligations
under this Agreement, no further registration statements (other than required
amendments or supplements to the original Registration Statement) will be filed
for the benefit of the Holders.

                                      B-1

<PAGE>

                  (d) The Company shall use its best efforts to obtain
effectiveness of the Registration Statement as soon as practicable and shall
continue to use its best efforts to maintain such effectiveness for the
registration until the date on which the Holder or his permitted transferee or
assignee no longer holds any shares of Common Stock acquired upon conversion of
the Convertible Note.

             2. Registration Expenses. Except as provided in Section 7 of this
Exhibit B, the Company shall pay all expenses incurred in connection with the
Registration Statement.

             3. Registration Procedures.

                  (a) In connection with the Company's obligation to register
the Common Stock under the Securities Act as provided in Section 1, the Company,
as expeditiously as possible and subject to the terms and conditions herein,
will:

                       (i)   use best efforts to cause the Registration
Statement filed with the SEC pursuant to Section 1(a) above to become effective
as soon as practicable.

                       (ii)  prepare and file with the SEC 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 and
to comply with the provisions of the Securities Act with respect to the
disposition of all securities covered by such Registration Statement until such
time as no Holder or his permitted transferee or assignee holds any such Common
Stock so covered.

                       (iii) furnish to the Holder such number of conformed
copies of such registration statement and of each such amendment and supplement
thereto (in each case including all exhibits), such number of copies of the
prospectus contained in such Registration Statement (including each preliminary
prospectus and any summary prospectus) and any other prospectus filed under the
Securities Act, in conformity with the requirements of the Securities Act, and
such other documents, in each case, as the Holder may reasonably request;

                       (iv)  use best efforts to register or qualify all Common
Stock covered by such Registration Statement under such other United States
state securities or blue sky laws of such jurisdictions as any of the Holder
shall reasonably request, to keep such registration or qualification in effect
for so long as such registration remains in effect, and to take any other action
which may be reasonably necessary or advisable to enable the Holder to
consummate the disposition of the Common Stock owned by the Holder in such
jurisdictions;

                       (v)   promptly notify the Holder at any time when a
prospectus relating to the Common Stock is required to be delivered under the
Securities Act, of the happening of any event as a result of which the
prospectus included in such Registration

                                      B-2

<PAGE>

Statement, as then in effect, includes an untrue statement of a material fact or
omits to state any material fact required to be stated therein or necessary to
make the statements therein not misleading in the light of the circumstances
under which they were made, or is otherwise not usable, and promptly prepare and
furnish to the Holder a reasonable number of copies of a supplement to or an
amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers of such Common Stock, such prospectus shall not
include an 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 in the light of the circumstances under which they were made, or use
all commercially reasonable efforts to take such other action as will render
such prospectus usable again;

                  (vi)   comply with all applicable rules and regulations of the
SEC, and not file (or withdraw or correct) any amendment or supplement to such
Registration Statement or prospectus to which a Holder shall have reasonably
objected in writing on the grounds that such amendment or supplement does not
comply in all material respects with the requirements of the Securities Act or
of the rules or regulations thereunder;

                  (vii)  provide a transfer agent and registrar for all Common
Stock covered by such Registration Statement not later than the effective date
of such Registration Statement; and

                  (viii) promptly list all Common Stock covered by such
Registration Statement on the AMEX or any securities exchange or automated
inter-dealer quotation system on which any of the Company Common Stock is then
listed or traded.

             (b) Each Holder agrees that upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 3(a)(v),
the Holder will forthwith discontinue any disposition of Common Stock pursuant
to the Registration Statement until the Holder receives copies of the
supplemented or amended prospectus contemplated by Section 3(a)(v) and, if so
directed by the Company, will deliver to the Company all copies, other than
permanent file copies, then in the possession of the Holder of the prospectus
relating to such Common Stock current at the time of receipt of such notice and
that such Holder will immediately notify the Company, at any time when a
prospectus relating to the registration of such Common Stock is required to be
delivered under the Securities Act, of the happening of any event as a result of
which information previously furnished by such Holder to the Company for
inclusion in such prospectus contains an untrue statement of a material fact or
omits to state any material fact required to be stated therein or necessary to
make the statements therein not misleading in the light of the circumstances
under which they were made.

             (c) As a condition of the fulfillment of its obligations under this
Agreement, the Company may require a Holder, at its own expense, to furnish the
Company with such information and undertakings regarding such Holder and the
distribution of such securities

                                      B-3

<PAGE>

as the Company may from time to time reasonably request in writing to the extent
necessary in order to cause the registration statement to comply with the
Securities Act, and a Holder shall provide such information and make such
undertakings as are requested.

                  (d) In connection with the preparation and filing of each
registration statement under the Securities Act, the Company will give each
Holder and such Holder's respective counsel and accountants, the reasonable
opportunity to participate in the preparation of such Registration Statement,
each prospectus included therein or filed with the SEC and each amendment
thereof or supplement thereto, and will give each of them such reasonable access
to its books and records and such reasonable opportunities to discuss the
business of the Company with its officers and the independent public accountants
who have certified its financial statements as shall be necessary to conduct a
reasonable investigation within the meaning of the Securities Act.

                  (e) Promptly after a sale of Common Stock pursuant to the
Registration Statement (assuming that no stop order is in effect with respect to
the registration statement at the time of such sale), the Company shall
cooperate with the Holders and provide the transfer agent for the Common Stock
with such instructions and legal opinions as may be required in order to
facilitate the issuance to the purchaser (or the Holder's broker) of new
unlegended certificates for such Common Stock.

             4. Indemnification; Contribution.

                  (a) To the extent permitted by applicable law, the Company
shall indemnify and hold harmless each Holder, each person, if any, who controls
such Holder within the meaning of the Securities Act, and each officer,
director, partner, and employee of such Holder and such controlling person,
against any and all losses, claims, damages, liabilities and expenses (joint or
several), including reasonable attorneys' fees and disbursements and expenses of
investigation, incurred by such party pursuant to any actual or threatened
action, suit, proceeding or investigation, or to which any of the foregoing
persons may become subject under the Securities Act, the Exchange Act or any
other federal or state laws, insofar as such losses, claims, damages,
liabilities and expenses arise out of or are based upon any of the following
statements, omissions or violations (collectively a "Violation"):

                       (i)  Any untrue statement or alleged untrue statement of
a material fact contained in such Registration Statement, including any
preliminary prospectus or final prospectus contained therein, or any amendments
or supplements thereto;

                       (ii) 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; or

                                      B-4

<PAGE>

                    (iii) Any violation or alleged violation by the Company of
the Securities Act, the Exchange Act, any applicable state securities law or any
rule or regulation promulgated under the Securities Act, the Exchange Act or any
applicable state securities law; provided, however, that the indemnification
required by this Section 4(a) shall not apply to amounts paid in settlement of
any such loss, claim, damage, liability or expense if such settlement is
effected without the consent of the Company (which consent shall not be
unreasonably withheld), nor shall the Company be liable in any such case for any
such loss, claim, damage, liability or expense to the extent (and only to the
extent) that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished to the
Company by the indemnified party expressly for use in connection with such
registration.

                (b) To the extent permitted by applicable law, each Holder shall
indemnify and hold harmless the Company, each of its directors, each of its
officers who shall have signed the registration statement, each person, if any,
who controls the Company within the meaning of the Securities Act, any other
Holder, any controlling Person of any such other Holder and each officer,
director, partner and employee of such other Holder and such controlling Person,
against any and all losses, claims, damages, liabilities and expenses (joint and
several), including reasonable attorneys' fees and disbursements and expenses of
investigation, incurred by such party pursuant to any actual or threatened
action, suit, proceeding or investigation, or to which any of the foregoing
Persons may otherwise become subject under the Securities Act, the Exchange Act
or any other federal or state laws, insofar as such losses, claims, damages,
liabilities and expenses arise out of or are based upon any Violation, 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 by such
Holder expressly for use in connection with such registration; provided,
however, that the indemnification required by this Section 4(b) shall not apply
to amounts paid in settlement of any such loss, claim, damage, liability or
expense if settlement is effected without the consent of the relevant Holder
(which consent shall not be unreasonably withheld); and, provided further that
in no event shall the amount of any indemnity under this Section 4(b) exceed the
gross proceeds from the applicable offering received by such Holder.

               (c)  Promptly after receipt by an indemnified party under this
Section 4 of notice of the commencement of any action, suit, proceeding,
investigation or threat thereof made in writing for which such indemnified party
may make a claim under this Section 4, such indemnified party shall 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 the defense thereof with counsel reasonably
satisfactory to the indemnified party; provided, however, that an indemnified
party shall have the right to retain its own counsel at its own expense (except
as specifically provided below). The failure to deliver written notice to the
indemnifying party within a reasonable time following the commencement of any
such action

                                      B-5

<PAGE>

shall not relieve such indemnifying party of any liability to the indemnified
party under this Section 4 except, if and to the extent that the indemnifying
party is actually prejudiced thereby, but in no event shall it relieve the
indemnifying party of any liability that it may have to any indemnified party
otherwise than pursuant to this Section 4. Any fees and expenses incurred by the
indemnified party (including any fees and expenses incurred in connection with
investigating or preparing to defend such action or proceeding) shall be paid to
the indemnified party, as incurred, within sixty (60) days of written notice
thereof to the indemnifying party (regardless of whether it is ultimately
determined that an indemnified party is not entitled to indemnification
hereunder, but in such event such amounts shall be immediately refunded). Any
such indemnified party shall have the right to employ separate counsel in any
such action, claim or proceeding and to participate in the defense thereof, but
the fees and expenses of such counsel shall be the expenses of such indemnified
party unless (i) the indemnifying party has agreed to pay such fees and expenses
or (ii) the indemnifying party shall have failed to promptly assume the defense
of such action, claim or proceeding or (iii) the named parties to any such
action, claim or proceeding (including any impleaded parties) include both such
indemnified party and the indemnifying party, and such indemnified party shall
have been advised by counsel that there may be one or more legal defenses
available to it which are different from or in addition to those available to
the indemnifying party and that the assertion of such defenses would create a
conflict of interest such that counsel employed by the indemnifying party could
not faithfully represent the indemnified party, it being understood, however,
that the indemnifying party shall not, in connection with any one such action,
claim or proceeding or separate but substantially similar or related actions,
claims or proceedings in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses of
more than one separate firm of attorneys (together with appropriate local
counsel) at any time for all such indemnified parties. No indemnifying party
shall be liable to an indemnified party for any settlement of any action,
proceeding or claim without the written consent of the indemnifying party, which
consent shall not be unreasonably withheld.

                (d) If the indemnification required by this Section 4 from the
indemnifying party is unavailable to an indemnified party hereunder in respect
of any losses, claims, damages, liabilities or expenses referred to in this
Section 4:

                    (i) The indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities or
expenses in such proportion as is appropriate to reflect the relative fault of
the indemnifying party and indemnified parties in connection with the actions
which resulted in such losses, claims, damages, liabilities or expenses, as well
as any other relevant equitable considerations. The relative fault of such
indemnifying party and indemnified parties shall be determined by reference to,
among other things, whether any violation has been committed by, or relates to
information supplied by, such indemnifying party or indemnified parties, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such Violation; provided however, that in no event shall the

                                      B-6

<PAGE>

obligation of any indemnifying party to contribute under this clause (i) exceed
the amount that such indemnifying party would have been obligated to pay by way
of indemnification if the indemnification provided for in Section 4(a) had been
available under the circumstances. The amount paid or payable by a party as a
result of the losses, claims, damages, liabilities and expenses referred to
above shall be deemed to include, subject to the limitations set forth in
Section 4(a) and (b), any legal or other fees or expenses reasonably incurred by
such party in connection with any investigation or proceeding.

                    (ii) The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 4(d) were determined by pro
rata allocation or by any other method of allocation that does not take into
account the equitable considerations referred to in Section 4(d)(i). No person
guilty of fraudulent misrepresentation within the meaning of Section 11(f) of
the Securities Act shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

                (e) The obligations of the Company and the Holder under this
Section 4 shall survive the completion of any offering of Common Stock pursuant
to a registration statement.

          5. Rule144; Exchange Act Filings. The Company shall file as and when
applicable, on a timely basis, all reports required to be filed by it under the
Exchange Act. If, for any reason the Company is not required to file reports
pursuant to the Exchange Act, upon the request of any Holder, the Company shall
make publicly available the information specified in subparagraph (c)(2) of Rule
144 of the Securities Act, and shall use best efforts to take such further
action as may be required from time to time and as may be within the control of
the Company, to enable the Holder to transfer the Common Stock to a transferee
without registration under the Securities Act within the limitation of the
exemptions provided by Rule 144 under the Securities Act or any similar rule or
regulation hereafter adopted by the SEC. The Company further covenants and
agrees that it will furnish to each Holder so long as such Holder owns Common
Stock promptly upon request, (i) a written statement by the Company as to the
status of its compliance 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 Holder
to sell such securities pursuant to Rule 144 without registration.

          6. Transfer or Assignment of Registration Rights. The rights of a
Holder provided herein to cause the Company to register the Common Stock may be
transferred or assigned prior to conversion of a Convertible Note, as and to the
extent a Convertible Note may be assigned, and afterwards with respect to any
Common Stock transferred by such Holder to up to three persons who are not
affiliates or owners of such Holder, or to any affiliate of such Holder, or to
any owner of such Holder.

                                      B-7

          7. Expenses of Registration.

                (a) Except as provided in Section 7(b) and 7(c) of this
Exhibit B, all expenses incurred in connection with a Registration pursuant to
this Agreement, whether or not a registration is consummated, shall be borne by
the Company, including (without limitation) charges, costs, expenses,
disbursements, fees and taxes in connection with (i) the preparation and filing
of any Registration Statement, each preliminary prospectus, the final
prospectus, and any amendments or supplements thereto, (ii) the preparation,
issuance and delivery of the certificates for the Common Stock offered and sold
thereunder, (iii) the qualification of the Common Stock for offering and sale
under state laws (including the legal fees and filing fees and other
disbursements of counsel in connection therewith), (iv) the filing for listing
or approval for quotation of the Common Stock on the American Stock Exchange or
on any national securities exchange (including the legal fees and filing fees
and other disbursements of counsel in connection therewith), (v) the fees and
expenses of any transfer agent or registrar for the Common Stock, and (vi) the
fees and disbursements charged by counsel or accountants to the Company.

                (b) Each Holder agrees to pay all underwriting discounts and
commissions and the fees and disbursements of any legal counsel retained by it,
other than the legal counsel referred to in clause (vii) of Section 7(a) above.
Additionally, the Company agrees to use its best efforts to cause its transfer
agent (or other designee) to serve as a custodian, to the extent any
underwriters participating in any such registration shall require the
participation of a custodian, for any selling security Holder and, in such
event, the Company shall be responsible for the fees and disbursements of such
person acting in such custodial capacity.

                (c) All expenses incurred in connection with a registration
which are, under this Section 7, to be borne by the Holders shall be borne pro
rata by the Holders included therein on the basis of the number of each Holder's
Common Stock included therein (or proposed to be registered, as the case may
be); provided, however, that if any such cost or expense is attributable solely
to one registered Holder and does not constitute a normal cost or expense of
such a registration, such cost or expense shall be allocated to and borne by
that registered Holder.

and  agrees as follows:

                (a) Debtor is the sole and exclusive owner of the entire and
unencumbered right, title and interest in the Intellectual Property Collateral,
free and clear of any liens, charges and encumbrances except for those created
hereunder and except for nonexclusive licenses granted by Debtor to its
customers in the ordinary course of business;

                (b) Performance of this IP Agreement does not conflict with or
result in a breach of any other agreement to which Debtor is bound, except to
the extent that certain agreements may prohibit the transfer or assignment of
the rights thereunder to a third party without the licensor's or other party's
consent, and this IP Agreement constitutes the grant of a security interest;

                (c) During the term of this IP Agreement, Debtor will not
transfer, assign, sell, hypothecate, or otherwise encumber any interest in the
Intellectual Property Collateral, except for nonexclusive licenses granted by
Debtor in the ordinary course of business or as set forth in this IP Agreement
and except for security interests in such Intellectual Property Collateral
existing as of the date hereof;

                (d) Debtor agrees that simultaneously with execution of this IP
Agreement, and upon any amendment of Exhibit A or B, Debtor shall execute the
form of Notice appended hereto as Schedule 1 (each, a "Notice") with respect to
each Patent or Trademark Collateral now owned or hereafter acquired, and shall
deliver it to Secured Party for recording in the Patent and Trademark Office so
as to record formally this IP Agreement.

                (e) Debtor shall promptly advise Secured Party of any material
adverse change in the composition of the Intellectual Property Collateral,
including but not limited to any ownership right of the Debtor in or to any
Trademark, Patent, Copyright, or other Intellectual Property Collateral
specified in this IP Agreement and any abandonment, forfeiture or dedication to
the public of the Computer Hardware and Software, Trademarks, Patents,
Copyrights and other Intellectual Property Collateral specified in this IP
Agreement;

                (f) Debtor shall (i) protect, defend and maintain the validity
and enforceability of the Trademarks, Patents, Copyrights and other Intellectual
Property Collateral, (ii) apply for registration of non-registered Hardware and
Software, Patent, Trademark and Copyright Collateral as they are created,
adopted or used and shall reasonably diligently prosecute such applications,
(iii) use its best efforts to detect infringements of the Trademarks, Patents,
Copyrights and other Intellectual Property Collateral and promptly advise
Secured Party in writing of material infringements detected, (iv) not forego any
right to protect and enforce rights to Trademarks, Patents, Copyrights or other
Intellectual Property Collateral, and (v) not allow any Trademarks, Patents,
Copyrights, or other Intellectual Property Collateral to be abandoned, forfeited
or dedicated to the public without the written consent of Secured Party,

                                      C-4

<PAGE>

which shall not be unreasonably withheld, unless Debtor determines that
reasonable business practices suggest that abandonment is appropriate;

                (g) Debtor shall promptly notify Secured Party of all
after-acquired intellectual property, whether owned, developed or acquired by
Debtor and shall notify Secured Party of any filed applications to register or
patents issued after the execution hereof. Any expenses incurred in connection
with such applications shall be borne by the Debtor.

                (h) Debtor shall take such actions as Secured Party may
reasonably request from time to time to perfect or continue the perfection of
Secured Party's interest in the Intellectual Property Collateral;

                (i) This IP Agreement creates, and in the case of after acquired
Intellectual Property Collateral, this IP Agreement will create at the time
Debtor first has rights in such after acquired Intellectual Property Collateral,
in favor of Secured Party a valid and perfected first priority security interest
in the Intellectual Property Collateral in the United States securing the
payment and performance of the obligations evidenced by the Note upon making the
filings referred to in clause (j) below;

                (j) To its knowledge, except for, and upon, the filing with the
United States Patent and Trademark Office with respect to the Patents and
Trademarks necessary to perfect the security interests created hereunder and
except as has been already made or obtained, no authorization, approval or other
action by, and no notice to or filing with, any U.S. governmental authority of
U.S. regulatory body is required either (i) for the grant by Debtor of the
security interest granted hereby or for the execution, delivery or performance
of this IP Agreement by Debtor in the United States or (ii) for the perfection
in the United States or the exercise by Secured Party of its rights and remedies
thereunder.

                (k) All information heretofore, herein or hereafter supplied to
Secured Party by or on behalf of Debtor with respect to the Intellectual
Property Collateral is accurate and complete in all material respects;

                (l) Debtor shall not enter into any agreement that would
materially impair or conflict with Debtor's obligations hereunder without
Secured Party's prior written consent, which consent shall not be unreasonably
withheld. Debtor shall not permit the inclusion in any material contract to
which it becomes a party of any provisions that could or might in any way
prevent the creation of a security interest in Debtor's rights and interest in
any property included within the definition of the Intellectual Property
Collateral acquired under such contracts, except that certain contracts may
contain anti-assignment provisions that could in effect prohibit the creation of
a security interest in such contracts;

                (m) Debtor shall not take any action, nor enter into any
license, royalty, assignment or other agreement which is inconsistent with
Debtor's obligations under this IP Agreement, or which has the effect of
reducing the value of the IP Collateral and shall give the Secured Party thirty
(30) days' prior written notice of any proposed license, royalty, assignment or
other agreement, except non-exclusive licenses granted by Debtor to its
customers in the ordinary course of business; and

                                      C-5

<PAGE>

                (n) Upon any executive officer of Debtor obtaining actual
knowledge thereof, Debtor will promptly notify Secured Party in writing of any
event that materially adversely affects the value of any material Intellectual
Property Collateral, the ability of Debtor to dispose of any material
Intellectual Property Collateral, and the rights and remedies of Secured Party
in relation thereto, including the levy of any legal process against any of the
Intellectual Property Collateral.

          5. Secured Party's Rights. Secured Party shall have the right, but not
the obligation, to take, at Debtor's sole expense, any actions that Debtor is
required under this IP Agreement to take but which Debtor fails to take, after
ten (10) days' notice to Debtor. Debtor shall reimburse and indemnify Secured
Party for all reasonable costs and reasonable expenses incurred in the
reasonable exercise of its rights under this Section 5.

          6. Responsibility of Debtor. In furtherance and not limitation of the
other provisions of this Section 6, Secured Party shall have no duty or
responsibility with respect to the Intellectual Property Collateral or its
preservation. Debtor acknowledges and agrees that it has reviewed the terms of
this IP Agreement with counsel of its choosing and that Debtor has determined
that neither execution, delivery nor performance of this Agreement by Debtor or
Secured Party will in any way impair the Intellectual Property Collateral or
Debtor's right, title and interest therein, subject to the purpose of this IP
Agreement which is to impose a lien thereon in favor of Secured Party.

          7. Conduct of Business; Inspection Rights. In order to preserve and
protect the goodwill associated with the Intellectual Property Collateral, the
Debtor covenants that it shall maintain the quality of the products and services
sold under or in connection with the Intellectual Property Collateral and shall
not at any time permit any impairment of the quality of said products and
services, and will provide the Secured Party from time to time with a
certificate to such effect signed by an officer of the Debtor upon request. The
Debtor hereby grants to the Secured Party and its employees and agents the right
to visit the Debtor's (or its affiliates') plants and facilities that
manufacture, provide, inspect or store products or services sold under any of
the Trademark Collateral, and to inspect the products and quality control
records relating thereto, at reasonable times during regular business hours. The
Debtor shall do any and all acts reasonably required by the Secured Party to
ensure the Debtor's compliance with this Section. Debtor hereby grants to
Secured Party and its employees, representatives and agents the right to visit
Debtor, during reasonable hours upon prior reasonable written notice to Debtor,
and any of Debtor's plants and facilities that manufacture, install or store
products (or that have done so during the prior six-month period) that are sold
utilizing any of the Intellectual Property Collateral, and to inspect the
products and quality control records relating thereto upon reasonable written
notice to Debtor and as often as may be reasonably requested; provided, however,
nothing herein shall entitle Secured Party access to Debtor's trade secrets and
other proprietary information. The foregoing provisions of this Section 7 shall
become applicable to Debtor at such time as Debtor has developed products and
services capable of being sold to the public.

<PAGE>

          8. Further Assurances; Attorney in Fact.

               (a) On a continuing basis, and at Debtor's sole expense, Debtor
shall, subject to any prior licenses, encumbrances and restrictions and
prospective licenses, make, execute, acknowledge and deliver, and file and
record in the proper filing and recording places in the United States, all such
instruments, including appropriate financing and continuation statements and
collateral agreements and filings with the United States Patent and Trademark
Office, and take all such action as may reasonably be deemed necessary or
advisable, or as requested by Secured Party, to create, preserve, continue,
charge, validate or perfect Secured Party's security interest in all Computer
Hardware and Software, Copyrights, Patents, Trademarks, and other Intellectual
Property Collateral and otherwise to carry out the intent and purposes of this
IP Agreement, or for assuring and confirming to Secured Party the grant or
perfection of a security interest in all Intellectual Property Collateral.

               (b) Debtor hereby irrevocably appoints Secured Party as Debtor's
attorney-in-fact, with full authority in the place and stead of Debtor and in
the name of Debtor, Secured Party or otherwise, from time to time in Secured
Party's discretion, upon Debtor's failure or inability to do so, to take any
action and to execute any instrument which Secured Party may deem necessary or
advisable to accomplish the purposes of this IP Agreement, including:

                    (i)   To modify, in its sole discretion, this IP Agreement
without first obtaining Debtor's approval of or signature to such modification
by amending any Exhibit hereof, as appropriate, to include reference to any
right, title or interest in any Copyrights, Patents, Trademarks, and other
Intellectual Property Collateral acquired by Debtor after the execution hereof
or to delete any reference to any right, title or interest in any Copyrights,
Patents, Trademarks, and other Intellectual Property Collateral in which Debtor
no longer has or claims any right, title or interest, provided that secured
Party shall deliver to Debtor written notice of such modification within a
reasonable time after such modification;

                    (ii)  To file, in its sole discretion, one or more financing
or continuation statements and amendments thereto, relative to any of the
Intellectual Property Collateral without the signature of Debtor where permitted
by law; and

                    (iii) Upon the occurrence of an Event of Default as defined
in Section 8, to endorse such Debtor's name on all applications, documents,
papers and instruments necessary for the Secured Party to use the Intellectual
Property Collateral, or to grant or issue any exclusive or non-exclusive license
under the Intellectual Property Collateral to any third person, or necessary for
the Secured Party to assign, pledge, convey or otherwise transfer title in or
dispose of the Intellectual Property Collateral, including the goodwill and
equipment associated therewith, to Secured Party or any third person.

               (c) Debtor hereby ratifies all that such attorney shall lawfully
do or cause to be done by virtue hereof. This power of attorney, being coupled
with an interest, shall be irrevocable for the life of this IP Agreement.

                                      C-7

<PAGE>

          9.  Events of Default. The occurrence of any of the following shall
constitute an Event of Default under this IP Agreement:

               (a)  an Event of Default occurs under the Note; or

               (b)  Debtor breaches any representation or warranty in this IP
Agreement; or

               (c)  Debtor creates, permits, or suffers the creation of any
liens, security interests, or any other encumbrances on any of its property,
real or personal, except (A) those in favor of Secured Party as security for the
Obligations, and (B) other valid and perfected security interests existing as of
the date hereof, provided that Debtor shall have ten (10) days to remove, or
purge or satisfy any such lien, security interest or encumbrance that is both
non-consensual and not in favor of any government entity; or

               (d) Debtor breaches any other covenant or agreement made by
Debtor in this IP Agreement, and such breach shall continue after the expiration
of thirty (30) days following the earlier of (i) notice from Secured Party to
Debtor of such failure, or (ii) the date on which the Debtor knew or should have
known of such failure.

          10. Remedies.

               (a) Upon the occurrence and continuance of an Event of Default,
Debtor's rights to use the Intellectual Property Collateral shall terminate
forthwith and Secured Party shall have the right to exercise all the remedies of
a secured party under the Uniform Commercial Code and any applicable federal
law, including without limitation the right to require Debtor to assemble the
Intellectual Property Collateral and any tangible property in which Secured
Party has a security interest and to make it available to Secured Party at a
place designated by Secured Party. Secured Party shall have a nonexclusive,
royalty free license to use the Copyrights, Patents, Trademarks, and other
Intellectual Property Collateral to the extent reasonably necessary to permit
Secured Party to exercise its rights and remedies upon the occurrence of an
Event of Default. Debtor will pay any expenses (including reasonable attorneys'
fees) incurred by Secured Party in connection with the exercise of any of
Secured Party's rights hereunder, including without limitation any expense
incurred in disposing of the Intellectual Property Collateral. All of Secured
Party's rights and remedies with respect to the Intellectual Property Collateral
shall be cumulative.

               (b) Upon the occurrence and continuance of an Event of Default,
without limiting the generality of the foregoing, the Secured Party may
immediately, without demand of performance and without advertisement, require
Debtor to assign of record the Intellectual Property Collateral to Secured Party
(or its assignees), and beneficially, sell at public or private sale or
otherwise realize upon, the whole or from time to time any part of the
Intellectual Property Collateral and the goodwill associated therewith, or any
interest which the Debtor has therein, and after deducting from the proceeds of
said sale or other disposition of the Intellectual Property Collateral all
expenses (including all reasonable expenses for brokers' fees and legal
services), shall apply the residue of such proceeds toward the payment of the
obligations as set forth in the Note and under applicable law. Any remainder of
the proceeds after payment in full

                                      C-8

<PAGE>

of the Note shall be paid over to the Debtor. Prior notice of any sale or other
disposition of the Intellectual Property Collateral need not be given to Debtor
unless otherwise required by law (and if notice is required by law, it shall be
given ten (10) days before the time of any intended public or private sale or
other disposition of the Intellectual Property Collateral is to be made, which
the Debtor hereby agrees shall be reasonable notice of such sale or other
disposition). At any such sale or other disposition, any holder of the Note
(including renewals and substitutions therefor) or the Secured Party may, to the
extent permissible under applicable law, purchase the whole or any part of or
interest in the Intellectual Property Collateral sold, free from any right of
redemption on the part of the Debtor, which right is hereby waived and released.

          11. Conduct of Business After Default. The parties understand and
agree that the collateral assignment with respect to the Intellectual Property
Collateral as provided for in this Agreement will and is intended to permit the
Secured Party and its successors and assigns, upon the occurrence and
continuance of an Event of Default as provided herein, to take title to and make
use of all rights to the Intellectual Property Collateral and to carry on the
business of the Debtor.

          12. Deficiency. If proceeds referred to in Section 10(b) above are
insufficient to pay the Note in full. Debtor shall continue to be liable for the
entire deficiency.

          13. Indemnity.

               (a) Debtor agrees to defend, indemnify and hold harmless Secured
Party and its directors, officers, employees, and agents from and against: (a)
all obligations, demands, claims, and liabilities claimed or asserted by any
other party in connection with the transactions contemplated by this IP
Agreement, including, without limitation, the assignment of the Intellectual
Property Collateral, the use of the Intellectual Property Collateral, the
alleged infringement by the Secured Party of the intellectual property rights of
others, any infringement action or other claim relating to the Intellectual
Property Collateral, or enforcement of the terms hereof (all of which shall
collectively be called the "Transactions") and (b) all losses or expenses in any
way suffered, incurred, or paid by Secured Party as a result of or in any way
arising out of, following or consequential to the Transactions under this IP
Agreement or otherwise under the transactions contemplated by this IP Agreement
or the Note (including without limitation, reasonable attorneys' fees and
reasonable expenses), except for losses arising from or out of Secured Party's
gross negligence or willful misconduct.

               (b) Debtor also agrees to defend, indemnify and hold harmless
Secured Party and each of its directors, officers, employees and agents, on
demand, from and against any and all losses, claims, obligations, damages, fees,
costs, liabilities, expenses or disbursements of any kind and nature whatsoever
(including but not limited to reasonable fees and disbursements of counsel,
interest, penalties, and amounts paid in settlement) incurred by the Secured
Party in connection with the payment or discharge of any taxes, counsel fees,
maintenance fees, encumbrances or otherwise protecting, maintaining, preserving
the Intellectual Property Collateral, or in defending or prosecuting any actions
or proceedings arising out of or related to the Intellectual Property
Collateral.

<PAGE>

          14. Reassignment.

               (a) At such time as Debtor shall completely and finally satisfy
