2. LEASE

         A. THE SYSTEM. BCI hereby leases to Customer, and Customers hereby
leases from BCI, the System. The System may either consist of new equipment or,
if indicated on the face hereof and Customer's purchase order, may consist of
used equipment.

         B. TITLE, SECURITY INTEREST. Title to System is and shall remain with
BCI. Customer will attach such labels as BCI may direct to show that the leased
System is owned by BCI. Customer hereby grants BCI a security interest in the
System, and BCI shall retain a security interest in the System until Customer
has made all payments to BCI required by this Agreement. Customer agrees to
cooperate with BCI in perfecting and maintaining BCI's security interest,
including the preparation, signing and filing of UCC financing statements.
Customer agrees that BCI is authorized, at its option, to file financing
statements or amendments thereto without the signature of Customer with respect
to any or all of the System and, if a signature is required by law, Customer
appoints BCI as Customers attorney-in-fact to execute any such financing
statement. BCI may assign or reassign its security interest in whole or in part,
without prior notice to Customer. Customer shall recognize each such assignment
and shall not assert against the assignee any defense, off-set or counterclaim
that Customer may have against BCI. Customer agrees that the System is and shall
remain personal property; that the System shall not be affixed or attached to
real property or any improvements thereon; and that Customer shall not sell,
secrete, mortgage, assign, transfer, lease, sublet, loan, part with possession
of, or encumber its interest in this Agreement, the System or any interest
therein, or permit any liens or charges to become effective thereon or permit or
attempt to do any of the acts aforesaid

         C. INSURANCE, LOCATION, OPERATION, RISK OF LOSS. Throughout the
duration of this Agreement Customer agrees: (i) to promptly pay all taxes,
assessments, license fees and other charges when levied or assessed against the
System or the ownership or use thereof; (ii) to immediately discharge any lien
other than BCI's that may arise or attach to the System; (iii) to insure the
System for full replacement value for all risks of loss; (iv) to not remove the
System or any part thereof from the "Ship to" location stated on the face
hereof; (v) to not misuse or abuse System; (vi) to not make any alterations,
additions or improvements to the System without the prior written consent of
BCI; and (vii) to assume the entire risk of loss or damage to System from any
cause from the date of shipment to Customer until its return to BCI, whether or
not covered by insurance. The occurrence of any such loss or damage shall not
relieve Customer of its obligations hereunder.


<PAGE>

         D. LICENSE TO COMPUTER SYSTEM AND SOFTWARE. All computer software
and/or programs, regardless of storage media, and all copies thereof, provided
with the System and/or provided by BCI from time to time during the term of this
Agreement (jointly and severally the "Software") shall at all times be and
remain the sole and exclusive property of BCI. BCI grants to Customer and
Customer accepts a limited, non-exclusive license to use the Software only in
conjunction with its operation of the System and only in accordance with BCI's
current operation and use instructions for the System. Customer shall not copy
or permit others to copy the Software or any portion thereof. Customer shall
return the Software to BCI on receipt from BCI or any third party of any
improved, enhanced or replacement Software. The license granted herein expires
at the end of this Agreement and may be terminated earlier by BCI: (a) upon
BCI's cancellation of this Agreement under Article 5.E., or (b) Customers
violation of any of the provisions of this Article 2.D. Customer may not
transfer the license granted hereunder to any third party.

3. PAYMENTS

         As indicated on the face of this Agreement, Customer will either pay
rental payments under Article 3.A. or metered System invoices under Article 3.B.

         A. RENTAL PAYMENTS. Customer shall pay to BCI the rental payment amount
shown on the face of this Agreement for each Plan Month.

         B. METERED SYSTEM PLAN. Customer shall send accurate, timely monthly
meter readings to BCI within three (3) days after the end of Plan Month. BCI
shall make monthly shipments of replenishment Reagents and Supply Items based
upon Customers volume of Tests and System usage as recorded by metering software
of the System. Depending upon whether the "Per Test", "Per Reportable" or "Per
Outcome" charge system has been indicated on the face of this Agreement, each
Plan Month charges shall accrue as shown by the metering software according to:
i) the charge per Test for the Tests actually performed in that month; or ii)
the charge per Reportable Test for the reportable results generated in that
month; or, iii) the charge per Outcome for the billable results generated in
that month.

         On the date BCI ships the System, BCI shall invoice Customer the Total
Monthly Investment. At the end of each Plan Month, BCI shall review Customers
total per Test/Reportable/Outcome charges accruing during that month. Customer
will be invoiced the greater of the per Test/Reportable/Outcome charges that
have accrued or the Total Monthly Investment. At the end of the last Plan Month
of the Term, Customer only shall be invoiced the amount by which the per Test
charges accruing that month exceed the Total Monthly Investment (this will be
invoiced only it the difference is a positive number). If meter data is not
received from Customer within seven (7) days after the end of the Plan Month,
the Total Monthly Investment will be invoiced, and a supplemental invoice will
be tendered upon receipt of the meter data if the per Test/Reportable/Outcome
charges for that Plan Month exceed the Total Monthly Investment. If the meter
data for a Plan Month should not be readable, the Total Monthly Investment will
apply for that Plan Month.

         For its convenience, Customer may request BCI to establish a meter read
date that will commence the initial Plan Month after the Term Commencement Date.
If BCI agrees with the request, then (i) BCI will set the meter read date as
requested, (ii) the Term will be extended by the number of days between the
meter read start date ("Meter Date") and the Term Commencement Date (the
"Interim Period"), (iii) the first Plan Month will begin on the Meter Date and
subsequent Plan Months will begin on each monthly anniversary of the Meter Date
during the Term, and (iv) BCI will invoice Customer an amount equal to (x) the
number of days in the Interim Period divided by (y) thirty (30), times (z) the
Total Monthly Investment.

         At any time, BCI may compare the quantities of Reagents and Supply
Items shipped to Customer against the quantities indicated by BCI standards for
the number of Tests recorded by the metering software. Reagents and Supply Items
delivered in excess of BCI standards may be invoiced at the list prices then in
effect.

         C. SECURITY DEPOSIT. Customer shall pay any security deposit shown on
the face of this Agreement upon the signing of this Agreement by Customer. Any
security deposit may be applied, at BCI's discretion, to any past due obligation
of Customer and to the extent not so applied, shall be returned to Customer,
without interest at the end of this Agreement.


<PAGE>

4. SERVICE

         If indicated on the face of this Agreement, BCI shall during its
regular business hours, and subject to the remainder of this Article, make all
necessary repairs and replacements to maintain the System in good working order.
The foregoing obligation of BCI is specifically conditioned upon Customers
compliance with Article 2.D. hereof. Repairs and replacements arising as a
result of: (i) Customers failure to properly perform the services and
maintenance required in the Operator's Manual, or (ii) from repairs by persons
other than BCI service personnel, or (iii) replacements with other than genuine
BCI parts, or (iv) from Customers negligence or negligent operation of the
System, or (v) from alterations or modifications to the System made by Customer,
including Customer installation or use of software not provided by BCI
specifically for the System, shall be made only at BCI's discretion and
Customer's expense.

5. GENERAL

         A. EFFECTIVE DATE, DURATION AND RENEWAL. This Agreement is effective
upon acceptance by an authorized BCI Official and ends when the Term and all
Renewal Term(s) have expired, all BCI invoices have been paid in full, and the
System has been returned to BCI. The initial Term is renewed automatically for
additional twelve (12) month terms (each renewal term a "Renewal Term"), unless
Customer gives BCI written termination notice at least ninety (90) days before
the end of the initial Term or any Renewal Term(s). BCI may cancel any automatic
renewal by sending the Customer written notice of termination at least fifteen
(15) days before the commencement of any Renewal Term. At the end of either the
initial Term (if no Renewal Term will continue) or the last Renewal Term,
Customer at its sole expense, shall promptly return the System to BCI at the
location designated by BCI, in the same condition as when received by Customer,
normal wear excepted.

         B. PRICE CHANGES. BCI may change the per Test/Outcome/Reportable and
Service rates from time to time during the term of this Agreement if: (i) The
price change takes effect after the initial twelve (12) months of the Term are
completed; and. (ii) Assuming the same mix and volume as in the twelve (12)
months preceding the change, in aggregate the effect of the change would not
exceed the greater of: (x) the percentage increase indicated for the Medical
Care Expenditure Category in the Consumer Price Index for all Urban Consumers
(unadjusted) from the later of the Effective Date or the effective date of the
last price change to Customer through the end of the month completed immediately
before the effective date of the change, or (y) differences in costs incurred by
BCI for raw materials and/or labor since the later of the Effective Date or the
last price change to Customer. In the event of any Government action which
prevents BCI from making a price change or continuing any price already in
effect, BCI may, on thirty (30) days prior written notice, cancel any portion of
this Agreement requiring BCI to deliver the affected Reagents or to provide
service hereunder. The remainder of this Agreement shall remain in full force
and effect.

         C. BILLING. Each invoice shall be paid by Customer within thirty (30)
days from the date of BCI's invoice. There are no discounts for prompt payment.
Prices stated on the face of this Agreement for the System, the Reagents or any
other goods or services provided to Customer hereunder do not include (i)
delivery and installation charges; or (ii) taxes, duties or other charges levied
by any Government, and any such applicable taxes, duties or other charges will
be added as a separate line item on the invoice unless Customer provides BCI
with satisfactory documentation certifying exempt status. Customer shall pay a
late payment charge equal to one and one-half percent (1 1/2%) per month, or the
highest interest rate permitted by law, whichever is less, of the late
payment(s). If BCI shall have any doubts at any time as to Customer's financial
responsibility, BCI may decline to make further deliveries hereunder except upon
receipt of cash or additional security or on other terms satisfactory to BCI.
Failure of Customer to provide such additional security or comply with such
other terms shall be grounds for BCI to cancel this Agreement in accordance with
the Default provisions hereof.

         D. DELIVERY. This order is subject to availability and will be
processed with reasonable efforts to meet requested delivery dates. BCI is not
obligated to make delivery by any specified date nor liable for damage due to
any delays. Customer shall accept the System and/or the Reagents on delivery.
BCI shall, if required by the operating and service instructions for the System,
install such System at the "Ship To" address on the face hereof.


<PAGE>

         E. DEFAULT. If Customer fails to make any payment specified in this
Agreement within thirty (30) days of the due date, if Customer breaches Article
2.D. of this Agreement, if Customer is in breach of any other obligation under
this Agreement and fails to cure that breach within fifteen (15) days following
notice from BCI, or if any credit or other information submitted by Customer to
BCI be untrue in any material respect, then BCI may, at its option and without
notice or demand, cancel this Agreement. In such event all amounts past due and
to become due under this Agreement shall become immediately due and payable.
Upon such cancellation BCI may issue an invoice to Customer for an amount
including any or all of the following: (i) all past due amounts; and (ii) the
product of (a) the number of months that were remaining in the Term prior to
cancellation by BCI multiplied by (b) either the Total Monthly Investment or the
rental payment amount shown on the face of this Agreement. Customer agrees to
pay such invoice within thirty (30) days of receipt thereof, and to promptly
return, at Customers sole expense and without demand or notice, the System to
BCI at the location designated by BCI, in the same condition as when received by
Customer, normal wear excepted. BCI and Customer acknowledge the difficulty in
establishing a value for the unexpired lease term and owing to such difficulty
agree that the provisions of this paragraph represent an agreed measure of
damages and are not to be deemed a forfeiture or penalty. The foregoing does not
preclude BCI from seeking or enforcing any other right or remedy available to it
under law or in equity and either serially or collectively, and BCI may elect to
suspend deliveries under this Agreement until a breach is cured. BCI's election
to suspend deliveries shall not preclude it from subsequently canceling this
Agreement. BCI shall not be deemed to have waived any rights hereunder by
accepting overdue payments nor shall waiver of the breach of any term of this
Agreement be deemed a waiver of future compliance. During any period Customer is
in default of any provision of this Agreement or is overdue in the making of any
payment, BCI shall be under no obligation to deliver reagents or supplies or to
provide service or to otherwise comply with any of its obligations under this
Agreement. Such BCI nonperformance shall not be construed as a breach of this
Agreement and Customer expressly waives it as a defense in any action. BCI shall
have no obligation, whether under statute or otherwise, to sell, lease or
otherwise use any equipment in mitigation of BCI's damage.

         F. LIMITED WARRANTY. BCI warrants that all instruments, systems and
accessories shall perform in all material respects for twelve (12) months from
delivery as set forth in BCI published product specifications (including any
applicable Year 2000 Statement of Compliance) and operator manuals in effect at
the time of delivery. BCI warrants that all reagents and consumables sold
hereunder shall conform in all material respects to the quantity and content
stated on the label and perform in all material respects consistent with
specifications for the lesser of twelve (12) months from delivery or until the
expiration date set forth on the label. THIS LIMITED WARRANTY IS PROVIDED IN
LIEU OF ALL OTHER WARRANTIES, AND ALL OTHER WARRANTIES, EXPRESS OR IMPLIED,
INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR A PARTICULAR
PURPOSE, ARE EXCLUDED, AND NONE SHALL BE CREATED, WHETHER UNDER THE UNIFORM
COMMERCIAL CODE, CUSTOM, PRACTICE, THE COURSE OF DEALING BETWEEN THE PARTIES OR
OTHERWISE. THIS WARRANTY SHALL NOT BE ALTERED BY THE WARRANTY OF ANY OTHER
PRODUCTS OR SYSTEMS TO WHICH THE SYSTEM OR OPTION MAY BE CONNECTED OR WHICH MAY
BE SUPPLIED BY BCI TO CUSTOMER UNDER THIS OR ANY OTHER AGREEMENT. BCI shall not
be obligated under this warranty if the need for repairs or replacements
directly or indirectly results from Customer's failure to store Reagents as
specified by BCI (including freezer or refrigerator storage) at all times after
delivery or from causes described in clauses i.-v. of Article 4. All
recommendations, statements and technical data regarding BCI's products are
based on tests which BCI believes to be reliable and correct. However, the
accuracy and completeness of such tests and the results thereof are not
guaranteed and are not to be construed as a warranty, either express or implied.
BCI assumes no obligation or liability for the advice given or the results
obtained, all such advice being given and accepted at Customer's sole risk.
Customer's exclusive remedy under this warranty, and BCI's sole obligation to
Customer under this warranty, is the repair or replacement (as selected by BCI)
of the non-conforming goods or services in accordance with this Article 5.F.

         G. LIMITATION OF LIABILITY. BCI shall not be liable for any special,
indirect, incidental or consequential damages, or interruption of business or
loss of profits. BCI's liability under this Agreement or arising from the
manufacture, installation, maintenance, repair or use of any System or Reagents
covered by or furnished under this Agreement, whether in tort, contract or
otherwise, is limited to an amount equal to the annual amount of the Agreement.

         H. AUTHORIZED REPRESENTATIVE. Each of the parties expressly represents
and warrants that the authorized representative signing this Agreement on their
behalf has the requisite authority and has been authorized by the party.


<PAGE>

         I. REGULATORY REQUIREMENTS. Customer acknowledges its obligation to
inform its employees, consultants and associates who will be using the System,
the Reagents and any other BCI products, of BCI's labeling literature and
notices relative thereto which BCI has or may hereafter provide to Customer. If
Customer files any cost reports or claims for reimbursement with federal health
care programs, Customer shall fully and accurately disclose and claim the
amount of any discount included under this Agreement in the fiscal year in which

contingency which would make performance commercially impracticable. Products
affected by such a shortage or event of force majeure may be eliminated from
this Agreement for the duration of that shortage or event of force majeure
without liability, but the Agreement shall otherwise remain in full force and
effect. BCI may during any period of shortage allocate its available supply of
products in any manner which it, in its sole discretion, deems appropriate.

         L. ELECTRONIC ACCESS. At its expense, Customer shall install and
maintain a telephone line or other communications access line requested and
specified by BCI (the "Port"), and shall permit BCI to connect the System to the
Port and maintain a connection between the System and the Port. BCI may use the
Port to gather billing data, to gather consumables replenishment data, to
analyze the performance of the System, to perform diagnostic and maintenance
functions and the like. BCI shall use the Port only for these purposes and shall
not access patient data. To the extent BCI may access or observe patient data
via the Port, BCI shall maintain that patient data in confidence and shall not
disclose that patient data to any third party.

California, but without regard to any conflicts of law provisions. The terms and
conditions of this Agreement are applicable to each System that may be included
in any Schedule that references this Agreement, is signed by an authorized
representative of Customer and is accepted by an authorized BCI official, and
