              MASTER LOAN AND SECURITY AGREEMENT
              ----------------------------------

Master Loan and Security Agreement No. S4330 Dated March 29, 1999

FINOVA Capital Corporation ("we," "us" or "FINOVA"), having its principal 
place of business at 1850 North Central Avenue, Phoenix, Arizona 85004, is 
willing to make a loan (the "Loan") to Advanced Polymer Systems, Inc., a 
Delaware corporation, APS Analytical Standards, Inc., a California 
corporation, Premier, Inc., a Connecticut corporation, and APS Joint Venture 
Corp., a Delaware corporation (jointly and severally, "you" or "Borrower"), 
each having its principal place of business at 123 Saginaw Drive, Redwood 
City, California 94063, under the terms and conditions contained in this 
Master Loan and Security Agreement (this "Master Agreement").  The Loan will 
be secured by the collateral (the "Collateral") described in the Schedule to 
the Note hereinafter defined ("Schedule").  The Collateral also includes any 
replacement parts, additions and accessories that you may add to the 
Collateral, as well as any proceeds of sale, lease or rental of the 
Collateral.  We may treat any Schedule as a separate loan and security 
agreement containing all of the provisions of this Loan and Security 
Agreement.

1. THE CREDIT
   ----------

We will make the Loan in one advance (the "Advance"), which shall be 
evidenced by the Schedule.  We will only make the Loan to you if all the 
conditions in this Master Agreement have been met to our satisfaction.  We 
will rely on your representations and warranties, contained in this Master 
Agreement, in making the Loan.  The terms of this Agreement will each apply 
to the Loan.

 - USE OF PROCEEDS.  You will use the proceeds of the Loan solely to 
refinance your purchases of the Equipment (as defined in the Schedule) (which 
Equipment shall be satisfactory to us in our sole discretion) and for general 
corporate purposes.  You will properly install the Collateral at your expense 
at your premises at 301 Laser Lane, Lafayette, Louisiana (the "Premises"), as 
indicated in the Schedule.  Because you have already paid for the Collateral, 
we will pay the Loan proceeds to you or to another person that you may 
designate in writing.

 - NOTE.  Your obligation to repay the Loan and to pay interest on the Loan 
will be evidenced by a promissory note (the "Note").  The Note will be dated 
the date of the Schedule.

 - TERM.  The Term of the Schedule (and the Loan) begins upon the date that 
we make the Loan to you (the "Closing Date").  The Term continues until you 
fully perform all of your obligations under this Agreement, the Schedule and 
the related Note.

 - LOAN ACCOUNT.  We will keep a loan account on our books and records (which 
are computerized) for the Loan.  We will record all payments of principal and 
interest in the loan account.  Unless the entries in the loan account are 
clearly in error, the loan account will definitively indicate the outstanding 
principal balance and accrued interest on the Loan.  We may send you loan 
account statements from time to time or upon your request.

 - PAYMENTS.  The scheduled loan payments (the "Payments") are indicated on 
the Schedule.  The Payments are payable periodically as specified on the 
Schedule from time to time (for example, monthly).  The Schedule also 
indicates that the Payments are payable "in advance".  You agree that you owe 
us the total of all of these Payments over the Term of the Schedule.

 - FIRST PAYMENT.  The first Payment is due at the beginning of the Term or 
at a later date that we agree to in writing.  Subsequent Payments are due on 
the thirtieth day of each successive period until you pay us in full all of 
the Payments and any other charges or expenses you owe us.

 - INTEREST.  Prior to maturity of the Schedule, you will pay us interest on 
the Schedule at the Interest Rate indicated in the Schedule. "Maturity" means 
the scheduled maturity or any earlier date on which we accelerate the Loan.  
The Payment amount indicated in the Schedule includes interest at this 
Interest Rate.  Interest is calculated in advance using a year of 360 days 
with twelve months of 30 days.

 - DEFAULT INTEREST RATE. After Maturity of the Loan you will pay us interest 
at a rate of four (4%) percent per year above the Interest Rate.  This is 
referred to as the "Default Rate."

 - INTERIM PAYMENT.  If the Loan is made on a day other than the thirtieth or 
thirty-first day of a period, you will also pay us an interim payment of 
interest, only, at the interest rate set forth on the Schedule, payable on 
the first Payment date.  The interim payment will be for the period from the 
beginning of the Term until the twenty-ninth day of the period in which the 
Loan is made, unless the Loan is made on the thirty-first day of a period.  
If the Loan is made on the thirty-first day of a period, the interim payment 
will be for the period from the beginning of the Term through and including 
the twenty-ninth day of the next following period.  The interim payment of 
interest will be calculated the same way as the regular installments of 
interest are calculated, but pro rata on a daily basis for the number of days 
for which the interim payment is due.

 - USURY.  You and we intend to obey the law.  If the Interest Rate charged 
would exceed the maximum legal rate, you will only have to pay the maximum 
legal rate.  You do not have to pay any excess interest over and above the 
maximum legal rate of interest.  However, if it later becomes legal for you 
to pay all or part of any excess interest, you will then pay it to us upon 
our request.

 - PAYMENT DETAILS.  You will make all payments due under this Master 
Agreement by 12:00 P.M., Connecticut time, on the day they are due.  You will 
make all payments in US Dollars (US$) in immediately available funds.  We do 
not have to make or give "presentment, demand, protest or notice" to get 
paid.  You waive "presentment, demand, protest and notice."

 - APPLICATION OF PAYMENTS.  Each payment under this Master Agreement is to 
be applied in the following order: first, to any fees, costs, expenses and 
charges you may owe us; second, to any interest due; and third to the 
principal balance.

 - PREPAYMENT.  You may prepay the Loan, in whole and not in part, but only 
as specifically permitted by Exhibit A to this Agreement.  You will give us 
at least 30 days advance written notice of prepayment.  You will pay us the 
prepayment premium indicated in the Schedule(s).  You will also pay us all 
accrued and unpaid interest through the date of prepayment, as well as all 
outstanding fees, costs, expenses and charges then due.  Of course, you will 
also pay the entire outstanding principal balance of the Loan.  Once you give 
us a notice of prepayment, that notice is final and irrevocable.  If we 
accelerate the Loan following an Event of Default, you will also owe us a 
prepayment premium calculated as if the Loan were prepaid on the date of 
acceleration.  If no prepayment is permitted, the premium due upon 
acceleration will be five (5%) percent of the outstanding principal balance.

 - YOUR OBLIGATION TO PAY US ALL PAYMENTS IS ABSOLUTE AND UNCONDITIONAL.  YOU 
ARE NOT EXCUSED FROM MAKING THE PAYMENTS, IN FULL, FOR ANY REASON.  YOU AGREE 
THAT YOU HAVE NO DEFENSE FOR FAILURE TO MAKE THE PAYMENTS AND YOU WILL NOT 
MAKE ANY COUNTERCLAIMS OR SETOFFS TO AVOID MAKING THE PAYMENTS.

2. SECURITY INTEREST
   -----------------

 - You grant us a first and only lien on and security interest in the 
Collateral.  The Collateral secures the full and timely payment and 
performance of all of your now existing or hereafter arising indebtedness, 
liabilities and obligations to us, whether under this Master Agreement, the 
Schedule, the Note and any other agreement, loan or lease that you may from 
time to time have with us, or otherwise (collectively, the "Obligations").  
You also grant us a security interest in any additional collateral identified 
in any Schedule.  Any additional collateral is considered to be "Collateral" 
and it secures all of the Obligations.

 - If we request, you will put labels supplied by us stating  "PROPERTY 
SUBJECT TO A SECURITY INTEREST HELD BY FINOVA CAPITAL CORPORATION" on the 
Collateral where they are clearly visible.

 - You give us permission to add to this Master Agreement or any Schedule the 
serial numbers and other information about the Collateral.

 - You give us permission to file this Master Agreement or a Uniform 
Commercial Code financing statement, at your expense, in order to perfect our 
security interest in the Collateral.  You also give us permission to sign 
your name on the Uniform Commercial Code financing statements where this is 
permitted by law.

 - You will pay our cost to do searches for other filings or judgments 
against you or your affiliates.  You will also pay any filing, recording or 
stamp fees or taxes resulting from filing this Agreement or a Uniform 
Commercial Code financing statement. You will also pay our fees in effect 
from time to time for documentation, administration and termination of this 
Master Agreement.

 - At your expense, you will defend our first priority security interest in 
the Collateral against, and keep the Collateral free of, any legal process, 
liens, other security interests, attachments, levies and executions.  You 
will give us immediate written notice of any legal process, liens, 
attachments, levies or executions, and you will indemnify us against any loss 
that results to us from these causes.

 - You will notify us at least 30 days before you change the address of your 
principal executive office, principal place of business, place where you keep 
your books and records or place where your Receivables (as defined in the 
Schedule) are generated.  Your principal executive office, principal place of 
business, place where you keep your books and records and the place where all 
of your Receivables are generated is 123 Saginaw Drive, Redwood City, 
California 94063.

 - You will promptly sign and return additional documents that we may 
reasonably request in order to protect our first priority security interest 
in the Collateral.

 - The Collateral (other than the Premises) is personal property and will 
remain personal property.  You will not incorporate it into real estate and 
will not do anything that will cause the Collateral to become part of real 
estate or a fixture.

3. CONDITIONS OF LENDING
   ---------------------

 - See our Commitment Letter to you dated February 26, 1999 (the "Commitment 
Letter"), which you and we consider to be a part of this Master Agreement.  
The terms and conditions of the Commitment Letter continue following the 
making of the Loan.  However, if there is a conflict between the terms and 
conditions of this Master Agreement, the Schedule or the Note and the terms 
and conditions of the Commitment Letter, then you and we agree that the terms 
and conditions of this Agreement, the Schedule and the Note control over the 
Commitment Letter terms and conditions.

 - Before we disburse any proceeds of the Advance, we also require the 
following:

 * That no payment is past due to us under any other agreement, loan or lease 
that you or any guarantor have with us.

 * That you are complying with all terms of this Agreement, the Schedule and 
the Note.

 * That we have received all the documents we requested, including the signed 
Schedule, Note, Delivery and Acceptance Certificate, and a mortgage in form 
and substance satisfactory to us (the "Mortgage") covering the Premises.

 * That there has been no material adverse change in your financial 
condition, business, operations or prospects, from the financial condition 
that you disclosed to us in your application for credit.

4. REPRESENTATIONS AND WARRANTIES
   ------------------------------

You represent and warrant to us as follows:

 - All financial information and other information that you have given us is 
true and complete.  You have not failed to tell us anything that would make 
the financial information misleading.  There has been no material adverse 
change in your financial condition, business, operations or prospects, from 
the financial condition that you disclosed to us in your application for 
credit.

 - You have supplied us with information about the Collateral.

 - You have complied with all "environmental laws" and will continue to 
comply with all "environmental laws."  No "hazardous substances" are used, 
generated, treated, stored or disposed of by you or at your properties except 
in compliance with all environmental laws.  "Environmental laws" mean all 
federal, state or local environmental laws and regulations, including the 
following laws: CERCLA, RCRA, Hazardous Materials Transport Act and The 
Federal Water Pollution Control Act.  "Hazardous substances" means all 
hazardous or toxic wastes, materials or substances, as defined in the 
environmental laws, as well as oil, flammable substances, asbestos that is or 
could become friable, urea formaldehyde insulation, polychlorinated biphenyls 
and radon gas.

 - You have taken all action necessary including but not limited to due 
inquiry and due diligence to assure that there will be no material adverse 
change to your business by reason of the advent of the year 2000, including 
without limitation that all computer-based systems, embedded microchips and 
other processing capabilities effectively recognize and process dates after 
April 1, 1999.

5. COVENANTS
   ---------

You agree to do the following things (or not to do the following things if so 
stated) until full payment of all amounts due to us under this Agreement, the 
Schedule and the Note:

CARE, USE, LOCATION, TRANSFER AND ALTERATION OF THE COLLATERAL
- --------------------------------------------------------------

 - You will make sure that the Collateral is maintained in good operating 
condition, and that it is serviced, repaired and overhauled when this is 
necessary to keep the Collateral in good operating condition.  All 
maintenance must be done according to the Supplier's or Manufacturer's 
requirements or recommendations. All maintenance must also comply with any 
legal or regulatory requirements.

 - You will maintain service logs for the Collateral and permit us to inspect 
the Collateral, the service logs and service reports.  You give us permission 
to make copies of the service logs and service reports.

 - We will give you prior notice if we, or our agent, want to inspect the 
Collateral or the service logs or service reports.  We may inspect it during 
regular business hours.  You will pay our travel, meals and lodging costs to 
inspect the Collateral, but only for one inspection per year.  If we find 
during an inspection that you are not complying with this Master Agreement, 
you will pay our travel, meals and lodging costs, our salary costs, and the 
costs and fees of our agents for reinspection.  You will promptly cure any 
problems with the Collateral that are discovered during our inspection.

 - You will use the Collateral only for business purposes.  You will obey all 
legal and regulatory requirements in your material use of the Collateral.

 - You will make all additions, modifications and improvements to the 
Collateral that are required by law or government regulation. Otherwise, you 
will not alter the Collateral without our written permission.  You will 
replace all worn, lost, stolen or destroyed parts of the Collateral with 
replacement parts that are as good or better than the original parts.  The 
new parts will become subject to our security interest upon replacement.

 - You will not remove the Collateral from the Premises indicated in the 
Schedule without our written permission.

 - You have and will have good and merchantable title to all of the 
Collateral.

 - You will not convey, assign, sell, mortgage, transfer, encumber, pledge, 
hypothecate, grant a security interest in, grant options with respect to, 
lease or otherwise dispose of all or any part of any interest whatsoever in 
or to any or all of the Collateral, including, without limitation, the 
Premises, or any interest therein, whether to a third party or to another 
Borrower. 

YEAR 2000 COMPLIANT
- -------------------

 - You shall take all action necessary including but not limited to due 
inquiry and due diligence with critical business partners to assure that 
there will be no material adverse change to your business by reason of the 
advent of the year 2000, including without limitation that all computer-based 
systems, embedded microchips and other processing capabilities effectively 
recognize and process dates after April 1, 1999.  At our request, you shall 
provide to us assurance reasonably acceptable to us that your computer-based 
systems, embedded microchips and other processing capabilities are year 2000 
compatible.

RISK OF LOSS
- ------------

 - You have the complete risk of loss or damage to the Collateral.  Loss or 
damage to the Collateral will not relieve you of your obligation to make the 
Payments.

 - If any Collateral is lost or damaged, you have two choices (although if 
you are in default under this Master Agreement, we and not you will have the 
two choices).  The choices are:

(1) Repair or replace the damaged or lost Collateral so that, once again, the 
Collateral is in good operating condition and we have a perfected first 
priority security interest in it.

(2) Pay us the present value (as of the date of payment) of the remaining 
Payments.  We will calculate the present value using a discount rate of five 
(5%) percent per year.  Once you have paid us this amount and any other 
amount that you may owe us, we will release our security interest in the 
damaged or lost Collateral and you (or your insurer) may keep the Collateral 
for salvage purposes, on an "AS IS, WHERE IS" basis.

INSURANCE
- ---------

 - Until you have made all Payments to us under this Master Agreement, the 
Schedule and the Note, you will keep the Collateral insured.  The amount of 
insurance, the coverage, and the insurance company must be acceptable to us.

 - If you do not provide us with written evidence of insurance that is 
acceptable to us, we may buy the insurance ourselves, at your expense.  You 
will promptly pay us the cost of this insurance.  We have no obligation to 
purchase any insurance.  Any insurance that we purchase will be our 
insurance, and not yours.

 - Insurance proceeds may be used to repair or replace damaged or lost 
Collateral or to pay us the present value of the Payments, as provided above.

 - You appoint us as your "attorney-in-fact" to make claims under the 
insurance policies, to receive payments under the insurance policies, and to 
endorse your name on all documents, checks or drafts relating to insurance 
claims for Collateral.

TAXES
- -----

 - You will pay all sales, use, excise, stamp, documentary and ad valorum 
taxes, license, recording and registration fees, assessments, fines, 
penalties and similar charges imposed on the ownership, possession, use, 
lease or rental of the equipment or on the Loan.

 - You will pay all taxes (other than our federal or state net income taxes) 
imposed on you or on us regarding the Payments.

 - You will reimburse us for any of these taxes that we pay or advance.

 - You will file and pay for any personal property taxes on the Collateral.

FINANCIAL INFORMATION
- ---------------------

 - During the Term you will promptly provide us with copies of all current, 
quarterly and annual reports and all proxy (or information) statements you 
file with the Securities and Exchange Commission (SEC).

 - You will also provide us with the following financial statements:

 * Quarterly balance sheet and statements of earnings and cash flow - within 
45 days after the end of your first three fiscal quarters in each fiscal 
year.  These will be certified by the chief financial officer.

 * Annual balance sheet and statements of earnings and cash flow - within 90 
days after the end of each fiscal year.  These will be audited by independent 
auditors acceptable to FINOVA.  Their audit report must be unqualified.

 * All financial statements will be prepared according to generally accepted 
accounting principles, consistently applied.  All financial statements and 
SEC filings that you provide us will be true and complete. They will not fail 
to tell us anything that would make them misleading.

 * At the same time you deliver the annual and quarterly financial statements 
described above, you will also provide us with a certificate of your chief 
financial officer stating that no default exists, or, if he cannot certify 
this because a default does exist, he must specify in reasonable detail the 
nature of the default.

 * So long as we have a security interest in the Receivables (as defined in 
the Schedule), you shall deliver to us, monthly, not later than the 10th day 
of each month, an accounts receivable aging by invoice, which shall be in 
form satisfactory to us.

6. DEFAULTS
   --------

You are in default if any of the following happens:

 - You do not pay us, within ten (10) days of its due date, any Payment or 
other payment that you owe us under this Master Agreement, the Schedule or 
the Note or that you owe under any other agreement, loan or lease that you 
have with us.

 - Any of the financial information that you give us is not true and 
complete, or you fail to tell us anything that would make the financial 
information not misleading.

 - You do something you are not permitted to do, or you fail to do anything 
that is required of you or you otherwise breach any term of or default under 
this Master Agreement, the Schedule, the Note, the Mortgage or any other 
lease, loan or other financial arrangement that you have with us, and the 
same is not cured within thirty (30) days after your receipt of written 
notice from us of such default.

 - An event of default occurs under any other lease, loan or obligation of 
yours that exceeds $25,000.

 - You file bankruptcy, or involuntary bankruptcy is filed against you.

 - You are subject to any other insolvency proceeding other than bankruptcy 
(for example, a receivership action or an assignment for the benefit of 
creditors).

 - Without our permission, you sell all or a substantial part of your assets, 
merge or consolidate, or a majority of your voting stock or interests is 
transferred or encumbered.

 - There is a material adverse change in your financial condition, business, 
operations or prospects, from the condition that you disclosed to us.

REMEDIES, DEFAULT INTEREST, LATE FEES
- -------------------------------------

If you are in default we may exercise one or more of our "remedies."  Each of 
our remedies is independent.  We may exercise any of our remedies, all of our 
remedies or none of our remedies.  We may exercise them in any order we 
choose.  Our exercise of any remedy will not prevent us from exercising any 
other remedy or be an "election of remedies."  If we do not exercise a 
remedy, or if we delay in exercising a remedy, this does not mean that we are 
forgiving your default or that we are giving up our right to exercise the 
remedy.  Our remedies allow us to do one or more of the following:

 - "Accelerate" the Loan balance under the Note.  This means that we may 
require you to immediately pay us all Payments for the entire Term for the 
Schedule.

 - Require you to immediately pay us all amounts that you are required to pay 
us for the entire Term of any other agreements, loans or leases that you have 
with us.

 - Sue you for all Payments and other amounts you owe us plus the Prepayment 
Premium (see Section 1 above).

 - We will have all of our rights and remedies under this Master Agreement, 
the Note, the Schedule, the Mortgage and all agreements, instruments and 
documents executed in connection herewith and therewith and all of our rights 
under applicable law, whether as a secured party or otherwise.

 - Require you at your expense to assemble the Collateral at a location we 
request in the United States of America.

 - Remove and repossess the Collateral from where it is located, without 
demand or notice, or make the Collateral inoperable.  We have your permission 
to remove any physical obstructions to removal of the Collateral.  We may 
also disconnect and separate all Collateral from other property.  No court 
order, court hearing or "legal process" will be required for us to repossess 
the Collateral.  You will not be entitled to any damages resulting from 
removal or repossession of the Collateral.  We may use, ship, store, repair 
or lease any Collateral that we repossess.  We may sell any repossessed 
Collateral at private or public sale.  You give us permission to show the 
Collateral to buyers at your location free of charge during normal business 
hours.  If we do this, we do not have to remove the Collateral from your 
location.  If we repossess the Collateral and sell it, we will give you 
credit for the net sale price, after subtracting our costs of repossessing 
and selling the Collateral.  If we rent the Collateral to somebody else, we 
will give you credit for the net rent received, after subtracting our costs 
of repossessing and renting the Collateral, but the credit will be discounted 
to present value using a discount rate equal to the Default Rate.  The credit 
will be applied against what you owe us under this Master Agreement, the 
Schedule, the Note and any other agreements, loans or leases that you have 
with us.  If the credit exceeds the amount you owe under this Master 
Agreement, the Schedule, the Note and any other agreements, loans or leases 
that you have with us, we will refund the amount of the excess to you.

 - So long as we have a lien on and security interest in the Receivables (as 
defined in the Schedule), we may deliver written notices to all of your 
account debtors (including, without limitation, Ortho Pharmaceutical 
Corporation) instructing them to pay all Receivables directly to us.  In 
furtherance of this right, you appoint us and our designees as your attorney, 
with the power to endorse your name on any checks, notes, acceptances, money 
orders or other forms of payment or security that come into our possession; 
to sign your name on any invoice or bill of lading relating to any 
Receivable, on drafts against customers, on assignments of Receivables, on 
notices of assignment, financing statements and other public records, on 
verifications of accounts and on notices to customers or account debtors; to 
send requests for verification of Receivables to customers or account 
debtors, to notify the post office authorities to change the address for 
delivery of your mail to an address designated by us and to open and dispose 
of all mail addressed to you; and to do all other things we deem necessary or 
desirable to carry out the terms of this Master Agreement.  You hereby ratify 
and approve all acts of such attorney.  Neither we nor our designees shall be 
liable for any acts or omissions nor for any error of judgment or mistake of 
fact or law while acting as your attorney.  This power, being coupled with an 
interest, is irrevocable until the Obligations have been fully satisfied.

 - Return conditions: Following an Event of Default, at our request you will 
return the Collateral, freight and insurance prepaid by you, to us at a 
location we request in the United States of America.  It will be returned in 
good operating condition, as required by Section 5 above.  The Collateral 
will not be subject to any liens when it is returned.  All advertising 
insignia will be removed and the finish will be painted or blended so that 
nobody can see that advertising insignia used to be there.

 * You will pack or crate the Collateral for shipping in the original 
containers, or comparable ones.  You will do this carefully and follow all 
recommendations of the Supplier and the Manufacturer as to packing or 
crating.

 * You will also return to us the plans, specifications, operating manuals, 
software documentation, discs, warranties and other documents furnished by 
the Manufacturer or Supplier.  You will also return to us all service logs 
and service reports, as well as all written materials that you may have 
concerning the maintenance and operation of the Collateral.

 * At our request, you will provide us with up to 60 days free storage of the 
Collateral at your location, and will let us (or our agent) have access to 
the Collateral in order to inspect it and sell it.

 * You will pay us what it costs us to repair the Collateral if you do not 
return it in the required condition.

You will also pay us for the following:

 - All our expenses of enforcing our remedies.  This includes all our 
expenses to repossess, store, ship, repair and sell the Collateral.

 - Our reasonable attorney's fees and expenses.

 - Default interest on everything you owe us from the date of your default to 
the date on which we are paid in full at the Default Rate.

You realize that the damages we could suffer as a result of your default are 
very uncertain.  This is why we have agreed with you in advance on the 
Default Rate to be used in calculating the payments you will owe us if you 
default.  You agree that, for these reasons, the payments you will owe us if 
you default are "agreed" or "liquidated" damages.  You understand that these 
payments are not "penalties" or "forfeitures."

LATE FEES
- ---------

You will pay us a late fee whenever you pay any amount that you owe us more 
than ten (10) days after it is due.  You will pay the late fee within one 
month after the late Payment was originally due.  The late fee will be ten 
(10%) percent of the late Payment.  If this exceeds the highest legal amount 
we can charge you, you will only be required to pay the highest legal amount.  
The late fee is intended to reimburse us for our collection costs that are 
caused by late Payment.  It is charged in addition to all other amounts you 
are required to pay us, including Default Interest.

7. EXPENSES AND INDEMNITIES
   ------------------------

PERFORMING YOUR OBLIGATIONS IF YOU DO NOT
- -----------------------------------------

If you do not perform one or more of your obligations under this Master 
Agreement or Schedule or Note, we may perform it for you.  We will notify you 
in writing at least ten (10) days before we do this.  We do not have to 
perform any of your obligations for you.  If we do choose to perform them, 
you will pay us all of our expenses to perform the obligations.  You will 
also reimburse us for any money that we advance to perform your obligations, 
together with interest at the Default Rate on that amount.  These will be 
additional "Payments" that you will owe us and you will pay them at the same 
time that your next Payment is due.

 - You will indemnify us, defend us and hold us harmless for any and all 
claims, expenses and attorney's fees concerning or arising from the 
Collateral, this Agreement, or any Schedule or Note, or your breach of any 
representation or warranty.  It includes any claims concerning the 
manufacture, selection, delivery, possession, use, operation or return of the 
Collateral.

 - This obligation of yours to indemnify us continues even after the Term is 
over.

8. MISCELLANEOUS
   -------------

WE MAY ASSIGN OR GRANT A SECURITY INTEREST IN THIS AGREEMENT, SCHEDULE, NOTE 
OR ANY PAYMENTS WITHOUT YOUR PERMISSION.  THE PERSON TO WHOM WE ASSIGN IS 
CALLED THE "ASSIGNEE."  THE ASSIGNEE WILL NOT HAVE ANY OF OUR OBLIGATIONS 
UNDER THIS MASTER AGREEMENT. YOU WILL NOT BE ABLE TO RAISE ANY DEFENSE, 
COUNTERCLAIM OR OFFSET AGAINST THE ASSIGNEE.

UNLESS YOU RECEIVE OUR WRITTEN PERMISSION, YOU MAY NOT ASSIGN OR TRANSFER 
YOUR RIGHTS UNDER THIS MASTER AGREEMENT OR ANY SCHEDULE. YOU ALSO ARE NOT 
ALLOWED TO LEASE OR RENT THE COLLATERAL OR LET ANYBODY ELSE USE IT UNLESS WE

2.  GRANTING CLAUSES.  Borrower hereby irrevocably and absolutely grants, 
assigns, mortgages, bargains, sells and conveys to Lender, with all POWERS OF 
SALE AND STATUTORY RIGHTS AND COVENANTS, and grants to Lender a security 
interest in all of Borrower's estate, right, title and interest in the 
Property, together with all proceeds thereof (including but not limited to 
Insurance Proceeds and Taking Proceeds as hereinafter defined) FOR THE 
PURPOSE OF SECURING payment of the Secured Debt and the due, prompt and 
complete observance, performance and fulfillment of each and every 
obligation, covenant, condition, warranty, agreement and representation of 
Borrower contained in the Loan Documents.  This Indenture is also intended to 
be a security agreement under the Uniform Commercial Code as in force, from 
time to time, in the State where the Improvements are located (the "State").

3.  ASSIGNMENT OF LEASES AND RENTS.   As additional collateral for the 
payment of the Secured Debt, Borrower hereby assigns to Lender the Leases, 
including the rents, income and profits of the Property, and grants the 
Lender the right to enter upon and take possession of the Property for the 
purpose of collecting the same and to let the Property or any part thereof, 
and to apply the rents, income and profits (after payment of all necessary 
charges and expenses) on account of the Secured Debt.  Until an Event of 
Default as hereinafter defined shall occur, Borrower shall be entitled to 
collect and receive said rents, income and profits.  Borrower warrants that: 
(a) Borrower is or will be the sole owner of the entire lessor's interest in 
the Leases; (b) the Leases are or will be valid and enforceable and have not 
been and will not be altered, modified, or amended in any manner whatsoever 
except as herein set forth; (c) no rents reserved in the Leases have been or 
will be assigned or anticipated; (d) no rents for any period subsequent to 
the date of this assignment have been or will be collected in advance of the 
time when the same shall become due under the terms of the Leases.  Borrower 
will not (i) execute any other assignment of its interest in the Leases or 
assignment of rents arising or accruing from the Lease or from the Property; 
(ii) alter, modify or change the terms of any Lease or give any consent to 
exercise any option required or permitted by such terms without the prior 
written consent of Lender; (iii) consent to any assignment or subletting 
under any Lease not in accordance with its terms, without the prior written 
consent of Lender.  If an Event of Default shall occur Borrower will, upon 
Lender's demand, pay monthly in advance to Lender or to any receiver 
appointed to collect said rents, income and profits, the fair and reasonable 
rental value for the use and occupation of the Property.  The exercise by 
Borrower of any right or remedy available under applicable law with respect 
to the Lease including without limitation, the collection of the rents, 
income and profits and the application thereof as herein provided shall not 
be considered a waiver of any default by Lender under this Indenture or the 
Lease or this assignment.  Lender shall not be liable for any loss sustained 
by Borrower resulting from Lender's failure to let the Property after default 
or from any other act or omission of Lender in managing the Property after 
default unless such loss is caused by the willful misconduct and bad faith of 
Lender.  Lender shall not be obligated to perform or discharge any 
obligation, duty, or liability under any Lease or under or by reason of this 
assignment.  Should Lender incur any such liability under any Lease or under 
or by reason of this assignment, or in defense of any such claims or demands, 
the amount thereof, including costs, expenses and reasonable attorneys' fees, 
shall be Secured Debt.

4. REPRESENTATIONS AND WARRANTIES.   Borrower hereby represents and warrants 
to Lender that the following are true, correct and complete as of date of the 
Indenture:

   4.1  Due Organization; Authority.   If Borrower is a corporation, 
partnership or a limited liability company, it is duly organized, validly 
existing and in good standing under the laws of the State of its organization 
and is duly qualified to conduct business and is in good standing in the 
State and has power to carry on its business as presently conducted, to own 
the Property, to make and enter into the Loan Documents and to carry out the 
transaction contemplated therein.

   4.2  Execution, Delivery and Effect of Loan Documents.   The Loan 
Documents have each been duly authorized, executed and delivered by Borrower, 
and each of the Loan Documents is a legal, valid and binding obligation of 
Borrower, enforceable in accordance with its terms.

   4.3  No Violation; Required Approvals.   Borrower is not in material 
violation of any term or provision of any document governing its organization 
or existence or in default under any material instruments or obligations 
relating to Borrower's business, assets or the Property and no claim or 
default relating to such instruments, assets, business, or the Property has 
been asserted against Borrower.  The execution and performance by Borrower of 
the Loan Documents and the consummation of the transactions contemplated 
thereby will not result in any material breach of, or constitute a material 
default under, any contract, agreement, document or other instrument to which 
Borrower is a party or by which Borrower may be bound or affected.  No 
approval by, authorization of, or filing with any federal, state or municipal 
or other governmental commission, board or agency or other governmental 
authority is required in connection with the authorization, execution and 
delivery of the Loan Documents.

   4.4  Construction and Completion of Improvements.   The Improvements have 
been completed and installed in a good and workmanlike manner, in compliance 
with the Laws as such term is hereinafter defined.  There are no contracts or 
agreements of any kind, either oral or in writing, now in existence covering 
labor or materials heretofore furnished or to be furnished in connection with 
the Property which are incomplete nor is any indebtedness outstanding for 
labor and materials in connection with the Property.

   4.5  Litigation.   There are no pending or threatened suits, judgments, 
executions, condemnation, proceedings, zoning changes or any other 
proceedings pending or of record in any court of any nature or before or by 
any governmental or administrative agency which could in any manner now or 
hereafter affect the Borrower's title to, possession of or use of the 
Property, or which could now be or hereafter constitute a lien thereon or 
materially or adversely affect the Property or Borrower or change the 
Property.  No petitions or cases have been filed by or against Borrower under 
any federal or state insolvency law.  No portion of the Property is subject 
to any right of redemption in favor of any third party under the foreclosure 
laws of the State.

   4.6  Financial Statements.   All statements, financial or otherwise, 
submitted to Lender in connection with the extension of credit evidenced by 
the Loan Documents are true, correct and complete in all material respects, 
and do not omit the statement of any fact or circumstance necessary to 
prevent the statement contained therein from being misleading or false and 
all such financial statements have been prepared in accordance with generally 
accepted accounting principles, consistently applied, and fairly present the 
financial condition of Borrower or entities covered by such statements as of 
the date thereof.  Since the date thereof, neither Borrower nor any such 
entity has experienced any material adverse change in its finances, business, 
operations, affairs or prospects.

   4.7  Title to Property.   Borrower has good and clear, record and 
marketable title to the Property, free of all liens, encumbrances or 
restrictions.

   4.8  Hazardous Waste.   To the knowledge of the Borrower, after due 
inquiry, the Land and Improvements have never been used as a land fill to 
receive solid waste, whether or not hazardous, and has not been used for 
disposal, storage or treatment of any waste, trash, garbage, industrial by--
product, chemical or hazardous substance of any nature, including without 
limitation radioactive containers, polychlorinated biphenyls, asbestos, 
pesticides, herbicides, pesticide or herbicide containers, untreated sewage, 
industrial process sludge or any "hazardous substance" as such term is 
defined in the Comprehensive Environmental Response, Compensation and 
Liability Act of 1980, as amended.  The Property does not now and will not 
contain asbestos insulation or electrical transformers cooled by 
phenylchlorobenzene.  To the knowledge of Borrower, after due inquiry, no 
release (a "Release") of oil or petroleum or chemical liquids or solids, 
liquid or gaseous products or hazardous substance has occurred on the Land or 
other real property in the State, now or previously owned by Borrower or any 
of the partners of Borrower (if Borrower is a partnership), or any of the 
stockholders or other persons having a legal or beneficial interest in 
Borrower (if Borrower is a corporation, trust or other legal entity).  
Borrower has not received any notice from any governmental agency or from any 
tenant under a Lease with respect to any such Release.

   4.9  Compliance with the Law.   The Improvements and the use to which the 
Borrower makes thereof, comply with all applicable restrictive covenants,

        (c) Taxes on Lender.   If the Laws impose upon Lender the obligation 
to pay the whole or any part of the Property Taxes and Charges or changes in 
any way the Laws relating to taxation so as to adversely affect the Loan 
Documents, then Borrower shall pay such Property Taxes and Charges or 
reimburse Lender for such adverse affect immediately therefor, unless in the 
opinion of counsel to Lender, it might be unlawful to require Borrower to pay 
the same or such payment might result in the imposition of interest 
prohibited by the Laws.

debts and liabilities incurred in the construction, operation, development,

disbursements, which may be imposed upon, asserted against or incurred or 
paid by Lender by reason of, on account of or in connection with any bodily 
injury or death or property damage occurring in, upon or in the vicinity of 
the Property through any cause whatsoever, or asserted against Lender on 
account of any act performed or omitted to be performed under the Loan

performed by Borrower under the Loan Documents, together with any other

the advent of the year 2000, including without limitation, that all computer-

in a condemnation or other taking for public or private use of the Property 
or which related to injury, or damage thereto (a "Taking"), Borrower shall 
immediately notify Lender describing the nature and the extent of the Taking 
or the Casualty, as the case may be.  Borrower shall promptly furnish to 
Lender copies of all notice, pleadings, determinations and other papers in

the insurance or other proceeds, if any, shall be sufficient or made 
available by Lender for the purpose) restore, repair, replace and rebuild the 
Property as nearly as possible to its quality, utility, value, condition and 
character immediately prior to the Casualty or the Taking, as the case may 
be.

compromise any claim for Insurance Proceeds or Taking Proceeds without 
Lender's prior written consent.

        (b) Assignment to Lender.   Borrower hereby assigns, sets over and

determines and with respect to the Notes as provided therein; or

purposes as it, in its sole discretion, deems advisable.

not be excused from the payment thereof in accordance with the terms of the 
Loan Documents.  Lender shall not, in any event or circumstance, be liable or 
responsible for failure to collect or exercise diligence in the collection of 
any Insurance Proceeds or Taking Proceeds.

Borrower.  Borrower hereby consents to the appointment of such receiver or 
receivers, waives any and all defenses to such appointment and agrees not to 
oppose any application therefor by Lender.  The appointment of such receiver, 
trustee or other appointee by virtue of any court order, or laws shall not 
impair or in any manner prejudice the rights of Lender to receive payment of 
rents and income; or

        (h) Uniform Commercial Code Remedies.   Exercise any and all rights

date of public sale of the Personalty or prior to the date, after which 
private sale of such Personalty will be made, shall constitute reasonable 
notice.  Any sale made pursuant to the provisions of this Paragraph shall be 
deemed to have been a public sale conducted in a commercially reasonable 
manner, if held contemporaneously with the sale of the remainder of the 
Property.  In the event of a foreclosure sale, whether made by Lender under

whole; or

elects, Borrower hereby expressly authorizes and appoints Lender or its 
designee as the Keeper of the Property pursuant to La.R.S. ss. 9:5136, et 
seq.  The reasonable compensation of the Keeper shall be secured by the lien 
of this Indenture; or

        (k) Louisiana Provisions.  This Indenture has been executed by 
Borrower pursuant to Louisiana Civil Code articles 3278 et seq., La. R.S. ss. 
9:4401, La. R.S. ss.9:5386-5388, Ln. R.S., ss. 10:1-101 et seq. (the "Uniform 
Commercial Code" or "UCC") and other applicable laws, for the purpose of 
securing the Secured Debt that may now be existing and/or that may arise in 
the future as provided herein, with the preferences and priorities provided 
under applicable Louisiana law .  In accordance with the requirements of 
applicable law, including Louisiana Civil Code art. 3288 and La. R.S. ss. 
9:4401, Borrower acknowledges, notwithstanding any other provision of this 
Indenture or any other Loan Document to the contrary, the maximum amount of 
Secured Debt secured hereby shall be U.S. $50,000,000.00.  Borrower 
authorizes Lender to file multiple originals, or photocopies, carbon copies, 
or facsimile copies of this Indenture or of such financing statements with 
the appropriate filing officer in the State of Louisiana pursuant to the 
provisions of the Uniform Commercial Code.  Borrower's employer 
identification number is accurately set out on the first page of this 
Indenture.  Borrower will not change its employer identification number or 
its name, identity or corporate structure so that any financing statement 
filed in connection herewith may become seriously misleading unless and until 
it notifies Lender in writing and executes all new appropriate financing 
statements or other such documents as Lender may require, with Borrower being 
required to pay the cost of such documentation and the filing thereof as 
provided above.

        (1) Other.   Take such other actions or commence such other 
proceedings under the Laws as Lender deems necessary or advisable to protect 
its interest in the Property and/or collect the Secured Debt.

Any sums advanced by Lender under this Paragraph or Paragraph 5.1 hereof 
shall bear interest at the interest rate specified in the Note plus 5%, (but 
in no event more than the maximum rate permitted by law); and shall be 
payable by Borrower on demand and such sums together with such interest 
thereon shall constitute a part of the Secured Debt.

   7.3  Holding Over.   Should Borrower, after an Event of Default, continue 
in possession of any part of the Property unlawfully, Borrower shall be a 
tenant from day to day, terminable at the will of either Borrower or Lender, 
at a reasonable rental per diem, such rental to be due and payable daily to 
Lender.

   7.4  General Provisions Relating to Remedies.

        (a) Cumulative Remedies.   All of the rights, remedies and options 
set forth herein or otherwise available at law or in equity are cumulative 
and concurrent and may be exercised without regard to the adequacy of or 
exclusion of, any other right, remedy, option or security held by Lender.

        (b) Right to Purchase.   At any sales of the Property pursuant 
hereto, Lender shall have the right to purchase the Property being sold, and 
in such cases the right to credit against the amount of the bid made therefor 
(to the extent necessary) all or any of the Secured Debt then due.  If Lender 
acquires the Property Borrower shall not be entitled to any proceeds of the 
further sale of the Property by Lender.

        (c) No Waiver or Release by Lender.   Lender may resort to any 
remedies and the security given by the Loan Documents in whole or in part, 
and in such portions and in such order as may seem best to Lender in its sole 
discretion, and any such action shall not in any way be considered as a 
waiver of any of the rights, benefits or remedies evidenced by the Loan 
Documents.  The failure of Lender to exercise any right, remedy or option 
provided for in the Loan Documents shall not be deemed to be a waiver of any 
of the covenants or obligations secured by the Loan Documents.  No sale of 
all or any of the Property, no forbearance on the part of Lender and no 
extension of the time for the payment of the whole or any part of the Secured 
Debt or any other indulgence given by Lender to Borrower or any other person 
or entity including, without limitation, any surrender, compromise, release, 
renewal, extension, exchange or substitution which Lender may grant in 
respect of the Property or any interest therein or any release or indulgence 
granted to any maker, endorser, guarantor or surety of any of the Secured 
Debt, shall operate to release or in any manner affect Lender's interest in 
the Property or the liability of Borrower to pay the Secured Debt, except to 
the extent that such liability shall be reduced by proceeds of sale of all or 
any of the Property received by Lender.

        (d) Waiver by Borrower.   Borrower hereby waives the benefit of any 
laws providing for appraisal or redemption, waives any right to bring or 
utilize any defense, counterclaim or setoff, other than one in good faith 
which denies the existence or sufficiency of the facts upon which the 
foreclosure action is grounded or which is based on Lender's wrongful 
actions.  If any defense, counterclaim or setoff (other than one permitted by 
the preceding sentence) is timely raised in such foreclosure action, such 
defense, counterclaim or setoff shall be dismissed.  If such defense, 
counterclaim or setoff is based on a claim which could be tried in an action 
for money damages, the foregoing waiver shall not bar a separate action for 
such damages (unless such claim is required by Laws or applicable rules of 
procedure to be pleaded in or consolidated with the action initiated by 
Lender) but such separate action shall not thereafter be consolidated with 
Lender's foreclosure action.  The bringing of such separate action for money 
damages shall not be deemed to afford any grounds for staying Lender's 
foreclosure action.  Borrower waives any and all right to a trial by jury in 
any action or proceeding based hereon.

8. GENERAL.

   (a)  Amendments.   The Loan Documents may not be waived, changed or 
discharged orally, but only by an agreement in writing and signed by Lender.  
Such permitted waiver, change or discharge shall be effective only in the 
specific instances and for the purposes for which given and to the extent 
therein specified.  Reference to any of the Loan Documents in this Indenture 
shall include all amendments, modifications, extensions and renewals thereof.

   (b)  Notices.   Any notice request, demand or other communication required 
or permitted under the Loan Documents (unless otherwise expressly provided 
therein) shall be given in writing by delivering the same in person to the 
intended addressee, by overnight courier service addressed as provided herein 
or as either Borrower or Lender shall have designated by written notice to 
the other.  Such notices shall be deemed given when received or, in the case 
of delivery by courier service with guaranteed next day delivery, the next 
day or the day designated for delivery, or in the case of delivery by 
certified United States Mail, two days after deposit therein.  No notice to 
or demand on Borrower in any case shall of itself entitle Borrower to any 
other or further notice or demand in similar or other circumstances.

   (c)  Successors and Assigns.   The terms, provisions, and conditions 
hereof shall be binding upon Borrower, and any permitted successors and 
assigns of Borrower, and shall inure to the Land.  All references in this 
Indenture to Borrower or Lender shall be deemed to include all such 
successors and assigns.

   (d)  Severability.   A determination that any provision of the Loan 
Documents is unenforceable or invalid shall not affect the enforceability or 
validity of any other provision, and any determination that the application 
of any provision of the Loan Documents to any person or circumstances is 
illegal or unenforceable shall not affect the enforceability or validity of 
such provision as it may apply to any other persons or circumstances.

   (e)  Joint and Several Liability.   If there is more than one Borrower, 
the obligations and covenants of each Borrower shall be joint and several.

   (f)  Governing Laws.   This Indenture shall be construed according to and 
governed by the Laws of the State.

   (g)  Publicity.  Lender is hereby authorized to issue appropriate press 
releases and to cause a tombstone to be published announcing the consummation 
of this transaction and the aggregate amount thereof.

   (h)  Captions.   All paragraph and subparagraph captions are for 
convenience of reference only and shall not affect the construction of any 
provision herein.

$4,000,000                                     March 29, 1999


ADVANCED POLYMER SYSTEMS, INC., a Delaware corporation, APS ANALYTICAL 
STANDARDS, INC., a California corporation, PREMIER, INC., Connecticut 
corporation, and APS JOINT VENTURE CORP., a Delaware corporation 
(individually and collectively, "you"), jointly and severally, promise to pay 
to the order of FINOVA CAPITAL CORPORATION ("we," "us" or "FINOVA") the 
principal amount of Four Million Dollars ($4,000,000), together with interest 
on the unpaid principal balance at the interest rate per annum and on the 
dates and as otherwise provided in the "Master Agreement" and "Schedule" 
referred to below.

If the interest rate charged would exceed the maximum legal rate, you will 
only have to pay the maximum legal rate.  You do not have to pay any excess 
interest over and above the maximum legal rate of interest.  However, if it 
later becomes legal for you to pay all or part of any excess interest, you 
will then pay it to us upon our request.

You will make all payments in US Dollars at our offices at 10 Waterside 
Drive, Farmington, Connecticut 06032-3065, or to another address that we 
request in writing.  All payments will be made in immediately available 
funds.

This Note is secured by a Master Loan and Security Agreement dated March 29, 
1999 (the "Master Agreement"), between you and FINOVA, the Mortgage dated 
March 29, 1999 executed by you, and by the Collateral and other collateral 
set forth on Exhibit A to the attached Schedule (the "Schedule"), dated the 
same date as this Note and made a part hereof.  All of the terms contained in 
the Schedule are incorporated in full herein as if set forth in its entirety.  
This Note may be accelerated by us upon a payment default or upon another 
default under the Master Agreement or Mortgage.

TIME IS OF THE ESSENCE.
- -----------------------

If you do not make a payment within ten (10) days after the date it is due, 
you will also pay us a late charge of ten percent (10%) of the amount past 
due.  Your interest rate will be increased by four percent (4%) per annum, 
over and above your regular interest rate if payment is not made at the 
scheduled or accelerated maturity of this Note.  You will also pay all of our 
costs of collection, including our reasonable attorney's fees and expenses.  
If we accelerate this Note, you will also owe a prepayment premium, as set 
forth in Exhibit A to the Master Agreement.

You waive diligence, presentment, formalities of demand, protest or notice of 
nonpayment or dishonor or any other notice as to this Note.

THIS NOTE IS GOVERNED BY THE SUBSTANTIVE LAWS (AND NOT THE CONFLICT OF LAWS 
PROVISIONS) OF THE STATE OF ARIZONA, THE STATE IN WHICH OUR OFFICE IS LOCATED 
IN WHICH FINAL APPROVAL OF THE TERMS AND CONDITIONS OF THIS NOTE OCCURRED AND 
FROM WHICH THE ORDER TO PAY THE LOAN FUNDS WAS MADE.  YOU CONSENT TO THE 
JURISDICTION OF ANY FEDERAL OR STATE COURT LOCATED IN THE STATE OF ARIZONA.  
YOU WAIVE TRIAL BY JURY.

You represent to us that the proceeds of the loan evidenced by this Note are 
being used to finance (or refinance) your purchase of the Collateral 
described in the Schedule, and that the Collateral will only be used for 
business purposes.

The obligations of each of you under this Note shall be joint and several.

                          SCHEDULE NO. 1 TO 
                MASTER LOAN AND SECURITY AGREEMENT

Schedule No. 1s dated March 29, 1999, (this "Schedule") to PROMISSORY NOTE 
NO. 1 and MASTER LOAN AND SECURITY AGREEMENT dated as of March 29, 1999 (the 
"Master Agreement") between ADVANCED POLYMER SYSTEMS, INC., a Delaware 
corporation, APS ANALYTICAL STANDARDS, INC., a California corporation, 
PREMIER, INC., a Connecticut corporation and APS JOINT VENTURE CORP., a 
Delaware corporation, each with its executive office and principal place of 
business at123 Saginaw Drive, Redwood City, California 94063 (collectively, 
"you"); and FINOVA CAPITAL CORPORATION, a Delaware corporation with its 
executive office and principal place of business at 1850 North Central 
Avenue, Phoenix, Arizona 85004 ("we," "us", or "FINOVA").

1.  OBLIGATION TO PAY.  You are presently borrowing Four Million Dollars 
($4,000,000) from us.  This borrowing is evidenced by your promissory note 
dated the same date as this Schedule in the amount of Four Million Dollars 
($4,000,000) (the "Note") to which this Schedule is attached and made a part 
thereof.

2.  PAYMENTS (SUBJET TO ADJUSTMENT IN PARAGRAPH 3).  You will repay the Loan, 
together with interest at the interest rate, in forty-eight (48) consecutive 
monthly payments of principal and interest each in the amount of  $107,120 
(the 48th consecutive monthly payment is referred to as the "Final Payment").  
These payments will be adjusted on the date we make the Loan to you as set 
forth in Paragraph 3.

The first monthly payment of principal and interest will be due on the date 
that we make the Loan to you.  The second monthly payment of principal and 
interest will be due on the thirtieth (30th) day of the month succeeding the 
month that we make the Loan to you and the remaining payments will continue 
on the same day in each and every month thereafter through and including the 
date upon which the Final Payment is scheduled to be due  (the "Maturity 
Date").  Any remaining amount that you owe us is due on the "Maturity Date." 

If the date we make the Loan to you is not the thirtieth (30th) or the 
thirty-first (31st) day of the month, you will pay, on the thirtieth (30th) 
day of the month in which we make the Loan to you (in the case of making the 
Loan the 30th), interest only, at the interest rate, from the date we make 
the Loan to you to the twenty-ninth (29th) day of the same month.  If the 
date we make the Loan to you is the thirty-first (31st), you will pay 
interest at the interest rate, from the date we make the Loan to you to the 
twenty-ninth (29th) day of the next following month.

The first monthly payment of principal and interest and the interim payment 
referred to above shall be payable on the date upon which we make the Loan to 
you and shall be withheld from the proceeds of the Loan.

3.  INTEREST; INDEXING.  The interest rate in your payments shown above is 
calculated at your regular rate of 8.70% per annum plus an "Index Rate" of 
4.81%.   The Index Rate means the highest yield, as published in THE WALL 
STREET JOURNAL of four-year United States Treasury Notes. Two-business days 
prior to the date we make the Loan to you, we will read THE WALL STREET 
JOURNAL to determine the final Index Rate.    If the Index Rate is not 
published in THE WALL STREET JOURNAL, we will determine it from another 
reliable source.  We will increase the payments set forth above in Paragraph 
2 to reflect any increase in the Index Rate.  We will give you notice of any 
increase as soon as we can.  You will pay the increased payments unless we 
have made an obvious mistake in our calculations.  Interest is calculated in 
advance using a 360-day year of twelve 30-day months.

4.  PURPOSE OF LOAN; SECURITY INTEREST.  You are making this borrowing to 
finance (or refinance) your purchase of the Equipment described in the 
attached Exhibit A to this Schedule.  The Equipment, together with all other 
property described on the attached Exhibit A (including, without limitation, 
the Receivables and the Premises) is hereinafter referred to as the 
"Collateral."  In order to secure all of the Obligations (as defined in the 
Master Agreement), you grant us a first lien on and security interest in the 
Collateral, as well as any additions, omissions, substitutions and proceeds 
of the Collateral.  You also grant us a security interest in any leases and 
rentals of the Collateral.  This security interest secures the Note.  It also 
secures the full and timely payment and performance of all of your other 
Obligations to us, whether under the Master Agreement, any other agreement, 
loan or lease that you may have with us, or otherwise.

5.  COLLATERAL ACCEPTANCE DATE.  The Equipment has been delivered, installed 
and accepted prior to the date hereof.  The Equipment is and at all times 
shall be located at 301 Laser Lane, Lafayette, Louisiana.  All Receivables 
shall be deemed to be located at 123 Saginaw Drive, Redwood City, California.

6.  TERMS OF MASTER AGREEMENT.  The terms of the Master Agreement are made a 
part of this Schedule as if repeated in its entirety in this Schedule.  Any 
declaration of default under the Master Agreement is a default under this 
Schedule and permits us to exercise all remedies provided by the Master 
Agreement.

7.  JOINT AND SEVERAL LIABILITY.  The indebtedness, liabilities and 
obligations of each Borrower under this Schedule shall be joint and several.
