                            Senior Secured Grid Note

Up to $7,500,000 February 9th, 2004

FOR VALUE RECEIVED, BIOACCELERATE, Inc., a Delaware corporation (the "Company"),

of all Tranches made to the Company by Payee (the "Principal Amount") pursuant
to the letter agreement, dated as of even date herewith, between the Company and
the Payee (the "Letter Agreement"), on the Maturity Date. Capitalized terms
used, and not defined, herein shall have the meanings ascribed thereto in the
Letter Agreement.

The Initial Tranche of will be immediately available to the Company, subject to
the satisfaction of all required conditions under the Letter Agreement.
Additional Tranches will be made available to the Company as per the agreed
budget thereafter from drawdown of initial tranche(each a "Funding Date"). Each
Additional Tranche will be funded within two (2) business days following receipt
by the Payee on a Funding Date of a Request Letter and a certification (in form

officer of the Company that all conditions to funding set forth herein have been
satisfied and that the Company is not in breach of any representation, warranty
or covenant provided in this Note, the Letter Agreement, the Security Documents,
the Security Agreement, any Warrant issued by the Company to the Payee, the
Engagement Letter or any agreement between the Company and either the Payee or
Bioaccelerate Limited related to the subject matter contained in such agreements
or documents.

The Company hereby authorizes the Payee to endorse on the Schedule of Tranches
annexed to this Note all Tranches made to the Company and all payments of
principal amounts in respect of such Traches, which endorsements shall, in the
absence of manifest error, be conclusive as to the outstanding principal amount
of all Tranches; provided, however, that the failure to make such notation with
respect to any Tranche or payment shall not limit or otherwise affect the
obligations of the Company under the Letter Agreement or this Note.

The Maturity Date shall mean the earliest of (i) the date on which any Placement
occurs, (ii) the date on which an Event of Default (as defined herein) occurs,
(iii) the date on which a Change in Control occurs. "Change in Control" shall
mean (a) a merger , consolidation or any other combination of the Company (other
than a merger, consolidation or combination of a wholly-owned subsidiary of the
Company or any other person or entity with respect to which the Payee has given
its approval in writing) with any entity or person, (b) the sale of all or
substantially all of the assets of the Company, or (c) the purchase by a single
entity or group, as defined in Section 13(d) of the Securities Exchange Act of
1934, as amended, of more than 25% of the voting stock of the Company in a
single transaction or a series of related transactions. A "Placement" shall mean
the closing of either debt or equity financing in which the Company receives at
least Twenty five Million Dollars ($25,000,000) in gross proceeds in any
transaction or series of related transactions after the date hereof. The
Principal Amount, accrued interest and any other amounts due under this senior
secured grid note (this "Note") are payable in such coin or currency of the
United States of America as at the time of payment shall be legal tender for the
payment of public and private debts. Interest on this Note shall accrue on the
Principal Amount outstanding from time to time at a rate per annum computed in
accordance with Section 4 hereof. This Note is made with full recourse to the
Company and upon all the warranties, representations, covenants and agreements
contained herein.

The Company (i) waives presentment, demand, protest or notice of any kind in
connection with this Note and (ii) agrees, in the event of an Event of Default
(as defined below), to pay to the holder of this Note, on demand, all reasonable
out-of-pocket costs and expenses (including legal fees) incurred in connection
with the enforcement and collection of this Note.

- Prepayments; Mandatory Prepayments. The Company may prepay at any time all or
any portion of the principal sum hereunder without penalty or premium; provided,
however, that (i) any prepayment (whether voluntary or involuntary) shall be
applied first to any accrued and unpaid interest hereunder up to the date of
such prepayment, then to any other sums which may be payable to Payee hereunder,
and then to the principal balance outstanding hereunder, and (ii) the acceptance
of any such prepayment following the occurrence and during the continuance of
any Event of Default hereunder shall not constitute a waiver, release or accord
and satisfaction thereof or of any rights with respect thereto by Payee.
Notwithstanding anything to the contrary provided herein or elsewhere, in the


                                     - 62 -
<PAGE>

event that prior to the Maturity Date, a Placement has occurred, then the
Company, upon the closing of such transaction or transactions, as the case may
be, will immediately repay in full the Principal Amount and all accrued and
unpaid interest thereon. The Company shall provide in any applicable financing
document that the Company uses in connection with any Placement that the
required amount of funds raised will be used to repay the Principal Amount and
all accrued and unpaid interest thereon and the Company shall provide to the
Payee no later than five (5) Business Days prior to the date of funding of any
such financing the date such financing is expected to close, the amount of
financing to be received and the place and time of such closing. The Company
shall provide to the Payee all other such applicable information the Payee shall
subsequently reasonably request. The Company shall provide to the Payee at the
closing of such financing in immediately available funds such funds as is
necessary to repay the entire Principal Amount and all accrued and unpaid
interest thereon.

- Day of Payment. Whenever any payment to be made hereunder shall become due and
payable on a day which is not a Business Day (as defined below), such payment
may be made on the next succeeding Business Day without being deemed past due
and, in the case of any payment of principal, such extension of time shall in
such case be included in computing interest on such payment. As used herein,
"Business Day" shall mean any day which is not a Saturday or Sunday and on which
banks in the State of New York are not authorized or required to close. Interest
on past due principal and accrued interest thereon shall be calculated as
follows: the amount of principal and interest past due multiplied by the Penalty
Interest Rate (as defined herein) and multiplied by a fraction, the numerator of
which is the number of days such principal and interest is past due and the
denominator of which is 360.

- Use of Proceeds. The Company shall use the proceeds of each Tranche solely for
the purposes as agreed with Bioaccelerate Inc.

1. Computation of Interest.

A. Base Interest Rate. Subject to subsections 4B and 4C below, the outstanding
Principal Amount shall bear interest per annum at the Applicable Federal Rate
(the "Base Interest Rate"), as defined in Section 1274(d) of the Internal
Revenue Code of 1986, as amended (the "Code"), payable on the Maturity Date.

B. Penalty Interest. In the event the Note is not repaid on the Maturity Date,
the rate of interest applicable to the unpaid Principal Amount and accrued
interest thereon shall be adjusted to ten percent (10%) per annum (the "Penalty
Interest Rate") from the date of default until repayment; provided, that in no
event shall the interest rate exceed the Maximum Rate provided in Section 4C
below.

C. Maximum Rate. In the event that it is determined that New York law is not
applicable to the indebtedness evidenced by this Note or that under New York law
("Applicable Usury Laws") the interest, charges and fees payable by the Company
in connection herewith or in connection with any other document or instrument
executed and delivered in connection herewith cause the effective interest rate
applicable to the indebtedness evidenced by this Note to exceed the maximum rate
allowed by law (the "Maximum Rate"), then such interest shall be recalculated
for the period in question and any excess over the Maximum Rate paid with
respect to such period shall be credited, without further agreement or notice,
to the Principal Amount outstanding hereunder to reduce said balance by such
amount with the same force and effect as though the Company had specifically
designated such extra sums to be so applied to principal and the Payee had
agreed to accept such extra payment(s) as a premium-free prepayment. All such
deemed prepayments shall be applied to the principal balance payable at
maturity.

2. Collateral. This Note is secured by a Security Agreement dated the date
hereof (as amended, modified or supplemented from time to time, the "Security
Agreement") of the Company in favor of the Payee covering all assets and future
assets of the Company therein described (collectively, the "Collateral"), and is
entitled to the benefits thereof. The Security Agreement, the Uniform Commercial
Code financing statements in connection with the Security Agreement, and any and
all other documents executed and delivered by the Company to the Payee under
which the Payee is granted liens on assets of the Company are collectively
referred to as the "Security Documents."

3. Covenants of Company.

A. Affirmative Covenants. The Company covenants and agrees with respect to the
Company and each of its Subsidiaries (which, for purposes of this Note means any
entity (i) in which the Company, directly or indirectly, owns 51% of the capital
stock or holds an equity or similar interest and (ii) which conducts substantive
business activities or holds material assets) that on and after the date hereof,
so long as this Note shall remain in effect, or the Principal Amount of, or
interest thereon, or any fee, expense or amount payable hereunder or with
respect to this Note shall be unpaid, it will perform the obligations set forth

Subsidiaries to, do or cause to be done all things reasonably necessary to

5. Representations of the Company. The Company represents and warrants to the
Payee that:

A. Corporate Organization; Etc. The Company and its Subsidiaries are
corporations duly organized, validly existing and in good standing under the
laws of the jurisdiction in which they are incorporated, and have the full
corporate power and authority to carry on their business as they are now being
conducted and to own the properties and assets they now own; are duly qualified
or licensed to do business as a foreign corporation in good standing in the
jurisdictions in which such qualification is required, except where the failure
to so qualify or to be so licensed would not have a Material Adverse Effect on
its business, financial condition, results of operations or on its ability to
continue to conduct its business as currently conducted. The copies of the
articles of incorporation and by-laws (or other relevant organization documents)
and any amendments thereto of the Company and each of its Subsidiaries
heretofore delivered to the Payee are complete and correct copies of such
instruments as currently in effect. As used in this Note, "Material Adverse
Effect" means any material adverse effect on the business, properties, assets,
operations, results of operations, prospects or financial condition of the
Company and its Subsidiaries, taken as a whole. The term "Material Adverse
Effect" does not include any material developments adversely affecting (i) the
industry in which the Company is engaged generally or (ii) the national economy,
security, stability or peace of the United States or any country, taken as a
whole.

B. Capitalization. The authorized, issued and outstanding capital stock of the
Company prior to the consummation of the transactions contemplated hereby is set
forth in Schedule 8B. All of such outstanding shares have been and are, or upon
issuance will be, validly issued, fully paid and non-assessable. Except as
disclosed in the schedule delivered to the Payee on the date hereof, (i) no
shares of the Company's capital stock are subject to preemptive rights under
Delaware law or any other similar rights or any liens or encumbrances suffered
or permitted by the Company; (ii) there are no outstanding debt securities
issued by the Company (other than as may be issued pursuant to the Letter
Agreement); (iii) there are no outstanding options, warrants, scrip, rights to
subscribe to, calls or commitments of any character whatsoever relating to, or
securities or rights convertible into, any shares of capital stock of the
Company or any of its Subsidiaries, or contracts, commitments, understandings or
arrangements by which the Company or any of its Subsidiaries is or may become
bound to issue additional shares of capital stock of the Company or any of its
Subsidiaries or options, warrants, scrip, rights to subscribe to, calls or
commitments of any character whatsoever relating to, or securities or rights
convertible into, any shares of capital stock of the Company or any of its
Subsidiaries; (iv) there are no agreements or arrangements under which the
Company or any of its Subsidiaries is obligated to register the sale of any of
their securities under the 1933 Act; (v) there are no outstanding securities of
the Company or any of its Subsidiaries which contain any redemption or similar
provisions, and there are no contracts, commitments, understandings or
arrangements by which the Company or any of its Subsidiaries is or may become
bound to redeem a security of the Company or any of its Subsidiaries; (vi) there
are no securities or instruments containing anti-dilution or similar provisions
that will be triggered by the issuance of this Note; and (vii) the Company does
not have any stock appreciation rights or "phantom stock" plans or agreements or
any similar plan or agreement. All prior sales of securities of the Company or
any of its Subsidiaries were either registered under the 1933 Act and applicable
state securities laws or exempt from such registration, and no security holder
has any rescission rights with respect thereto except to the extent any such
rights would not reasonably be expected to have a Material Adverse Effect.

C. Title. Except as set forth in or contemplated by the schedule to be delivered
to the Payee on the date hereof, the Company has good and marketable title to
all material properties and assets owned by it, free and clear of all liens,
charges, encumbrances or restrictions, except as not prohibited by Section
6(B)(vi) hereof or such as are not significant or important in relation to the
Company's business; all of the material leases and subleases under which the
Company is the lessor or sublessor of properties or assets or under which the
Company holds properties or assets as lessee or sublessee are in full force and
effect, and the Company is not in default in any material respect with respect
to any of the terms or provisions of any of such leases or subleases, and no
material claim has been asserted by anyone adverse to rights of the Company as
lessor, sublessor, lessee or sublessee under any of the leases or subleases
mentioned above, or affecting or questioning the right of the Company to
continued possession of the leased or subleased premises or assets under any
such lease or sublease. .

D. Intellectual Property Rights. The Company and its Subsidiaries own or possess
adequate rights or licenses to use all trademarks, trade names, service marks,
service mark registrations, service names, patents, patent rights, copyrights,
inventions, licenses, approvals, governmental authorizations, trade secrets and
rights necessary to conduct their respective businesses as now conducted. Except
as set forth on the schedule delivered to the Payee on the date hereof, none of
the Company's trademarks, trade names, service marks, service mark
registrations, service names, patents, patent rights, copyrights, inventions,


                                     - 69 -
<PAGE>

licenses, approvals, government authorizations, trade secrets or other
intellectual property rights has expired or terminated, or is expected to expire
or terminate within two years from the date of this Note, except where such
expiration or termination would not have either individually or in the aggregate
a Material Adverse Effect. The Company and its Subsidiaries do not have any
knowledge of any infringement by the Company or its Subsidiaries of trademarks,
trade name rights, patents, patent rights, copyrights, inventions, licenses,
service names, service marks, service mark registrations, trade secrets or other
similar rights of others, or of any such development of similar or identical
trade secrets or technical information by others and, except as set forth on
such schedule, no claim, action or proceeding has been made or brought against,
or to the Company's knowledge, has been threatened against, the Company or its
Subsidiaries regarding trademarks, trade name rights, patents, patent rights,
inventions, copyrights, licenses, service names, service marks, service mark
registrations, trade secrets or other infringement, except where such
infringement, claim, action or proceeding would not reasonably be expected to
have either individually or in the aggregate a Material Adverse Effect. Except
as set forth on such schedule, the Company and its Subsidiaries are unaware of
any facts or circumstances which might give rise to any of the foregoing. The
Company and its Subsidiaries have taken reasonable security measures to protect
the secrecy, confidentiality and value of all of their intellectual properties
except where the failure to do so would not reasonably be expected to have
either individually or in the aggregate a Material Adverse Effect.

E. Litigation. Except as set forth in or contemplated by the schedule delivered
to the Payee on the date hereof, there is no material action, suit,
investigation, customer complaint, claim or proceeding at law or in equity by or
before any court, arbitrator, governmental instrumentality or authority or other
agency now pending or, to the knowledge of the Company, threatened against the
Company, the adverse outcome of which would be reasonably likely to have a
Material Adverse Effect. The Company is not subject to any judgment, order,
writ, injunction or decree of any Federal, state, municipal or other
governmental department, commission, board, bureau, agency or instrumentality,
domestic or foreign which have a Material Adverse Effect.

F. Taxes. Except as set forth in or contemplated by the schedule delivered to
the Payee on the date hereof, the Company has filed all Federal, state, local
and foreign tax returns which are required to be filed by it or otherwise met
its disclosure obligations to the relevant agencies and all such returns are
true and correct in all material respects. The Company has paid or adequately
provided for all tax liabilities of the Company as reflected on such returns or
determined to be due on such returns or pursuant to any assessments received by
it or which it is obligated to withhold from amounts owing to any employee,
creditor or third party. There are no unpaid taxes in any material amount
claimed to be due by the taxing authority of any jurisdiction, and the officers
of the Company know of no basis for any such claim. The Company has properly
accrued all taxes required to be accrued by GAAP consistently applied. The tax
returns of the Company have never been audited by any state or Federal
authorities. The Company has not waived any statute of limitations with respect
to taxes or agreed to any extension of time with respect to any tax assessment
or deficiency.

G. Compliance With Laws; Licenses; Etc. The business of the Company and its
Subsidiaries is not being conducted in violation of any law, ordinance or
regulation of any governmental entity except for such violations the sanctions
for which either individually or in the aggregate would not reasonably be
expected to have a Material Adverse Effect, and the Company has not received
notice of any violation of or noncompliance with any Federal, state, local or
foreign, laws, ordinances, regulations and orders applicable to its business
which has not been cured, the violation of, or noncompliance with which, would
be reasonably likely to have a Material Adverse Effect. The Company has all
material licenses and permits and other governmental certificates,
authorizations and permits and approvals (collectively, "Licenses") required by
every Federal, state and local government or regulatory body for the operation
of its business as currently conducted and the use of its properties, except
where the failure to be licensed or possess a permit would not reasonably be
expected to have a Material Adverse Effect. The Licenses are in full force and
effect and to the Company's knowledge no violations currently exist in respect
of any License and no proceeding is pending or threatened to revoke or limit any
thereof.

H. Existing Indebtedness. The schedule delivered to the Payee on the date hereof

showing as to each item of such indebtedness the obligor, the aggregate
principal amount outstanding and a brief description of any security therefor
(after giving effect to the application of the proceeds of the sale of this
Note). The Company is not in default in any material respect in the performance
or observance of any of the terms, covenants or conditions contained in any
instrument evidencing any such indebtedness and no event has occurred and is
continuing which, with notice or the lapse of time or both, would become such a
default.

and are perfected in accordance with applicable laws and regulations on the date

Company have not issued any securities convertible into, or options or warrants
for, any common or preferred equity securities thereof, except as set forth on
such schedule. Except as set forth on such schedule, there are no agreements,
voting trusts or understandings binding on the Company or any of its
Subsidiaries restricting the transfer of the voting securities of any of the

L. Absence of Certain Restrictions. No indenture, certificate of designation for
preferred stock, agreement or instrument to which the Company or any of its

Letter Agreement), prohibits or limits in any way, directly or indirectly the
ability of any such Subsidiary to make Restricted Payments or repay any
indebtedness to the Company or to another Subsidiary of the Company.

Security Act of 1974, as amended from time to time, and the rules and
regulations issued thereunder, as from time to time in effect ("ERISA") and the
Code, where applicable, in all material respects and no ERISA Event has occurred

Pension Plan; (iv) the incurrence by the Company or its Subsidiaries or any
ERISA Affiliate of any liability under Title IV of ERISA with respect to the

Plan or Pension Plans or to appoint a trustee to administer any Pension Plan;
(vi) the incurrence by the Company or any of its Subsidiaries or any ERISA

performance or the payment of any amounts which may have been assigned to them

b. The Lender authorizes Grantor to collect its accounts, provided that such
collection is performed in a prudent and businesslike manner, and the Lender
may, upon the occurrence and during the continuation of any Event of Default and

in respect of Instruments of Grantor and obligors in respect of Chattel Paper of
Grantor that the Accounts and the right, title and interest of Grantor in, to
and under such Contracts, Instruments and Chattel Paper have been assigned to

so notify such Account Debtors, parties to such Contracts, obligors in respect
of such Instruments and obligors in respect of such Chattel Paper. Upon the
occurrence and during the continuance of any Event of Default, the Lender may,
in Lender's name or in the name of others, communicate with such Account
Debtors, parties to such Contracts, obligors in respect of such Instruments and
obligors in respect of such Chattel Paper to verify with such parties, to the

Account Debtors of Grantor except upon the occurrence of any Event of Default.

carry on its business as now being conducted, and (c) is duly qualified to do

the Obligations, a legally valid and binding lien on, pledge of, and security
interest in the Collateral and, upon the filing of a UCC Financing Statement,
and any applicable filings with respect to Copyrights, Patents or Trademarks in
respect of the Collateral, such lien, pledge and security interest will be
perfected and will have priority over the claims of any other present and future
creditors of the Company (other than Permitted Liens or liens upon such of the
Collateral that must be perfected by possession or control of such Collateral);
and

d. Grantor's chief executive office, principal place of business and the place
where Grantor maintains its records concerning the Collateral are each presently

grant any option with respect to any of the Collateral, except Inventory in the
ordinary course of business.

b. Grantor shall not, directly or indirectly, create or permit to exist any lien
upon or with respect to any of the Collateral, and shall defend the Collateral

c. Grantor shall maintain all tangible Collateral in good condition and repair,
ordinary wear and tear excepted.

d. Grantor shall maintain on the Collateral property damage and liability

companies as are customarily maintained by businesses similar to Grantor. Each
such policy shall not be materially altered or canceled, and the coverage will
not be materially reduced, in any case, without at least thirty (30) days' prior
written notice to the Lender. Grantor shall provide the Lender with satisfactory
evidence of such insurance coverage at the request of the Lender.

e. Grantor shall promptly pay when due all property and other taxes, assessments

proceedings and adequate reserves are being maintained in connection therewith;
provided that this Section 7(f) shall not apply to claims for labor, materials
or supplies which Payee consents in writing shall be excluded herewith,

reasonably complete records of the Collateral. Grantor shall furnish the Lender

Trademarks and promptly advise the Lender in writing of material infringements

8. Further Assurances. Grantor agrees, at any time and from time to time, at the
expense of Grantor, and upon request of the Lender, to promptly execute and
deliver all further instruments and documents, and take all further action, that
may be necessary or desirable, in order to perfect and protect any security
interest granted or purported to be granted hereby or to enable the Lender to
exercise and enforce Lender's rights and remedies hereunder with respect to any
Collateral, including, without limitation, (i) delivering and causing to be
filed any financing or continuation statements (including "in lieu" continuation
statements) under the UCC with respect to the security interests granted hereby,
(ii) obtaining "control" by or on behalf of Lender of any Investment Property,
Deposit Accounts, Letter-of-Credit Rights or Electronic Chatter Paper (with
reference to applicable provisions of the UCC with respect to "control" for such
items of Collateral), (iii) placing the interest of the Lender as lien holders
on the certificate of title (or similar evidence of ownership) of any Equipment
constituting Collateral owned by Grantor which is covered by a certificate of
title (or similar evidence of ownership), (iv) filing or cooperating with the
Lender in filing any forms or other documents required to be recorded with the
United States Patent and Trademark Office, United States Copyright Office, or
any actions, filings, recordings or registrations in any foreign jurisdiction or
under any international treaty, required to secure or protect Lender's interest
in the Collateral, (v) transferring Collateral to the possession of the Lender
(if a security interest in such Collateral can only be perfected by possession),
(vi) executing and delivering or causing to be delivered written notice to
insurers of Lender's security interest in, or claim in or under, any policy of
insurance (including unearned premiums), and (vii) using its best efforts to
obtain acknowledgements from bailees having possession of any Collateral and
waivers of liens from landlords and mortgagees of any location where any of the
Collateral may from time to time be stored or located. If Grantor executes and
delivers any document or instrument pursuant to this Section 8, such document or
instrument shall be in form and substance reasonably satisfactory to the Lender
and a copy thereof shall be provided by Grantor to the Lender; and if Grantor
takes any other action pursuant to this Section 8, such action shall be taken
with the prior written consent of the Lender and notice thereof shall be given
by Grantor to the Lender.

9. Security Interest Absolute. All rights of the Lender and the assignment and
security interest hereunder, and all obligations of Grantor hereunder, shall
remain in full force and effect and shall secure the Obligations, and shall be
absolute and unconditional, irrespective of:

a. any change in the time, manner or place of payment 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 Note; or

b. any taking, exchange, release or non-perfection of any other collateral, or
any release or amendment or waiver of or consent to departure from any guaranty,
for all or any of the Obligations; or

c. any manner of application of any Collateral, or proceeds thereof, to all or
any of the Obligations or any manner of sale or other disposition of any
Collateral; or

d. any other circumstances other than releases, waivers and the like by the
Lender that might otherwise constitute a defense available to, or a discharge
of, Grantor's obligations hereunder or Lender's security interest hereunder.

10. Continuing Security Interest; Sale of Participations; Release of Collateral.
This Agreement shall create a continuing security interest in the Collateral and
shall (i) remain in full force and effect until the payment in full of the
Obligations (subject to Section 14 hereof), (ii) be binding upon Grantor, its
successors and its permitted assigns under the Note, and (iii) inure to the
benefit of, and be enforceable by (subject to the terms hereof), the Lender and
its successors and assigns. No sales of participations in, and no other sales,
assignments, transfers or other dispositions of, any agreement governing or
instrument evidencing the Obligations or any portion thereof or interest therein
by the Lender shall in any manner affect the lien granted to the Lender
hereunder. Subject to Section 14 hereof, upon the payment in full of the
Obligations, the security interest granted hereby shall terminate and all rights
to the Collateral shall revert to Grantor. Upon any such termination, the Lender
will, at Grantor' expense, execute and deliver to Grantor such documents as
Grantor shall reasonably request to evidence such termination. The Lender shall,
at the request of Grantor, deliver any document reasonably necessary to release
any lien granted hereunder with respect to any Collateral Grantor is
transferring.

11. Lender's Duties. The powers conferred on the Lender hereunder are solely to
protect Lender's interest in the Collateral as a secured party and shall not
impose any duty upon the Lender to exercise any such powers. Except for the safe
custody of any Collateral in Lender's possession and the accounting for money
actually received by Lender hereunder, the Lender shall not have any duty as to
any Collateral or as to the taking of any necessary steps to preserve any rights


                                     - 79 -
<PAGE>

pertaining to any Collateral. The Lender shall not have any responsibility or
liability for the collection of any proceeds of any Collateral or by reason of
any invalidity, lack of value or uncollectability of any of the Collateral. The
Lender shall be deemed to have exercised reasonable care in the custody and
preservation of any Collateral in the Lender's possession if such Collateral is
accorded treatment substantially equal to that which the Lender accords its own
property.

12. Events of Default; Remedies Upon Default; Actions by Lender.

a. The occurrence of an Event of Default under and as defined in the Note shall
constitute an "Event of Default" hereunder.

b. If any Event of Default shall have occurred:

i. The Lender may exercise in respect of the Collateral, in addition to other
rights and remedies provided for herein or otherwise available to Lender (or any
of them), all the rights and remedies of a secured party on default under the
UCC (whether or not the UCC applies to the affected Collateral), and may also,
without notice of any kind or demand of performance or other demand (all and
each of which demands and notices are hereby expressly waived to the maximum
extent provided by the UCC and other applicable law) reclaim, take possession,
recover, store, maintain, finish, repair, prepare for sale or lease, advertise
for sale or lease and sell the Collateral or any part thereof in one or more
parcels at public or private sale, at any exchange, broker's board or at the
Lender's offices or elsewhere, for cash, on credit, or for future delivery, and
upon such other terms as the Lender may deem commercially reasonable. In
connection with the liquidation, sale or other disposition of the Collateral,
the Lender is granted a non-exclusive, royalty-free license or other right to
use, without charge, Grantor' labels, patents, copyrights, trade secrets, trade
names, trademarks, service marks, or any similar property as it pertains to the
Collateral, in completing a liquidation, sale or other disposition of the
Collateral. The Lender shall not be obligated to make any sale of Collateral
regardless of notice of sale having been given. The Lender may adjourn any
public or private sale from time to time by announcement at the time and place
fixed therefor, and such sale may, without further notice, be made at the time
and place to which it was so adjourned. Grantor agrees that in any sale of any
of the Collateral, whether at a foreclosure sale or otherwise, the Lender is
hereby authorized to comply with any limitation or restriction in connection
with such sale as it may be advised by counsel is necessary in order to avoid
any violation of applicable law (including compliance with such procedures as
may restrict the number of prospective bidders and the Lender, require that such
prospective bidders and the Lender have certain qualifications and restrict such
prospective bidders and the Lender to Persons who will represent and agree that
they are purchasing for their own account for investment and not with a view to
the distribution or resale of such Collateral), and Grantor further agrees that
such compliance shall not result in such sale being considered or deemed not to
have been made in a commercially reasonable manner, nor shall the Lender be
liable or accountable to Grantor for any discount allowed by reason of the fact
that such Collateral is sold in compliance with any such limitation or
restriction.

ii. Grantor authorizes the Lender, on the terms set forth herein, to enter the
premises where the Collateral (or any part of it) is located, to take possession
of the Collateral (or any part of it), and to pay, purchase, contract, or
compromise any encumbrance, charge or lien which, in the opinion of the Lender,
appears to be prior or superior to its security interest. Grantor further
agrees, at the Lender's request, to assemble the Collateral and make it
available to the Lender at places which the Lender shall reasonably select. To
the maximum extent permitted by applicable law, Grantor hereby waives all
claims, damages, and demands against the Lender arising out of the repossession,
retention or sale of the Collateral.

iii. The Lender may sell Collateral without giving warranties as to such
Collateral. The Lender may specifically disclaim any warranties of title or the
like. The foregoing will not be considered adversely to affect the commercial
reasonableness of any sale of Collateral.

iv. If the Lender sells any of the Collateral upon credit, Grantor will be
credited only with, and at the time of, payments actually made by the purchaser
in such sale received by the purchaser and applied to the indebtedness of such
purchaser. In the event the purchaser in such sale fails to pay for the
Collateral, the Lender may resell the Collateral and Grantor shall be credited
with the proceeds of the resale in accordance with the preceding sentence. In
the event the Lender purchase any of the Collateral being sold, the Lender may
pay for the Collateral by crediting some or all of the amounts described in
clauses first, second, third and fourth of Section 12(b)(vi) hereof.

v. Any cash held by the Lender as Collateral and all cash proceeds received by
the Lender in respect of any sale of, collection from, or other realization
upon, all or any part of the Collateral or the exercise of any other remedies
consequent upon an Event of Default shall be applied in whole or in part by the
Lender against all or any part of the Obligations in the following order:


                                     - 80 -
<PAGE>

First, to the Lender in an amount sufficient to pay in full the Obligations,
including all reasonable fees, costs, expenses, liabilities and advances
incurred or made by the Lender in connection with the sale, disposition or other
realization of the Collateral, including without limitation, reasonable
attorneys' fees;

Second, upon payment in full of all the Obligations, to Grantor or to whomsoever
may be lawfully entitled to receive such surplus.

vi. Grantor shall remain liable for any deficiency if the proceeds of any sale
or disposition of the Collateral are insufficient to fully pay the Obligations,
and Grantor also shall be liable for the reasonable costs and expenses
(including reasonable attorneys' fees and expenses) incurred by Lender to
collect such deficiency.

vii. Grantor hereby waives presentment, demand, protest or any notice (to the
maximum extent permitted by applicable law) of any kind in connection with this
Agreement or any Collateral.

13. Expenses. Grantor shall upon demand pay to the Lender the amount of any and
all reasonable expenses, including the reasonable and necessary fees and
expenses the Lender's counsel and of any experts and agents, which the Lender
may incur in connection with (a) the administration of this Agreement, (b) the
custody or preservation of, or the sale of, collection from, or other
realization upon, any of the Collateral, (c) the exercise or enforcement of any
of the rights of the Lender hereunder, or (d) the failure by Grantor to perform

16. Cumulative Remedies. The rights and remedies hereunder provided are
cumulative and may be exercised singly or concurrently, and are not exclusive of
any rights and remedies provided by law. The Lender shall not by any act, delay,

including, without limitation, obtaining insurance coverage for the Collateral
and satisfying tax obligations or liens on the Collateral. Grantor shall
reimburse the Lender on demand for all reasonable expenses and reasonable
attorneys' fees incurred by the Lender in performing any such obligation,
including interest at the interest rate specified in the Note.

b. Grantor hereby absolutely and irrevocably constitutes and appoints the Lender
as Grantor's true and lawful agent and attorney-in-fact, with full power of

absolute discretion, reasonably determine as necessary or advisable for the
purpose of maintaining, preserving or protecting the security constituted by

proper in or for the purpose of exercising any of such powers, authorities or
discretions, in each case. Grantor hereby ratifies and confirms, and hereby
agrees to ratify and confirm, whatever lawful acts the Lender or any of its
agents, nominees or attorneys shall do or purport to do in the exercise of the
power of attorney granted to the Lender pursuant to this Section 17(b), which
power of attorney, being given for security, is irrevocable. Notwithstanding
anything to the contrary in this Section 17(b), no such action as Grantor's true
and lawful agent and attorney-in-fact may be taken by Lender except upon the
occurrence of any Event of Default.

provided for hereunder shall be in writing and mailed by registered or certified

thereof. Every right, power or remedy of the Lender shall continue in full force
and effect until such right, power or remedy is specifically waived by an
instrument in writing executed by the Lender.

20. Severability. Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

its successors and assigns, and in the event of an assignment of all or any of
the Obligations, the rights hereunder, to the extent applicable to the
indebtedness so assigned, may be transferred with such indebtedness. This

assigns.
