fund Schedules under this Lease shall terminate on the Commitment Termination
Date.  Lessor may, in its sole discretion, terminate its commitment herein to
fund the Lessor's Commitment or any unfunded portion thereof at any time if:
(a) there is any material adverse change to the general affairs, management,
results of operations, condition (financial or otherwise) or prospects of
Lessee, whether or not arising from transactions in the ordinary course of
business, (b) there is any material adverse deviation by Lessee from the
business plan of Lessee presented to and not disapproved in writing by Lessor,
since the date first written on the cover page of this Lease, (c) any Event of
Default exists, or (d) if any term or condition in any Schedule is not
satisfied by the Delivery Date of such Schedule.  This Lease shall constitute a
"Finance Lease" under Division 10 of the California Uniform Commercial Code
("UCC"); provided, however, that the characterization of this Lease as a
"Finance Lease" is for purposes of Division 10 of the UCC only, and shall not
affect the accounting treatment of this Lease.  This Lease, and Lessee's
obligation to pay all rent and other sums hereunder, shall be absolute and
unconditional, and shall not be subject to, and Lessee hereby waives any right
of or to, abatement, reduction, set-off, defense or counterclaim.  Lessee
waives any and all rights and remedies conferred upon Lessee by UCC Sections
10508 through 10522, including (without limitation) Lessee's rights to (i)
cancel or repudiate this Lease, (ii) reject or revoke acceptance of the leased
property, (iii) recover damages from Lessor for breach of warranty or for any
other reason, (iv) claim a security interest in any rejected property in
Lessee's possession or control, (v) deduct from Rental Payments all or any part
of any claimed damages resulting from Lessor's default under this





                                       2
   5
Lease, (vi) accept partial delivery of the Equipment, (vii) "cover" by making
any purchase or lease of other property in substitution for property due from
Lessor, (viii) recover from the Lessor any general, special, incidental or
consequential damages, for any reason whatsoever, and (ix) seek specific
performance, replevin or the like for any of the Equipment.  Lessee
acknowledges that, at the time of each Schedule, it will have received and
approved the terms of the agreements with the vendors under which Lessor will,
subject to the terms and conditions of this Lease, purchase the Units covered
by such Schedule.  The Units shall be leased for commercial purposes only, and
not for consumer, personal, home or family purposes.  This Lease describes the
terms of, and is intended by the parties hereto to be, a true lease; provided,
however, that the parties acknowledge that the terms and conditions of the
Lease may, alternatively, create a secured financing or lease for security.  If
this Lease as supplemented by any Schedule constitutes a security agreement or
lease for security, the Lessee hereby grants a security interest to Lessor in
all of Lessee's right, title and interest in the Units described in Annex A to
such Schedule and the proceeds thereof, to secure all of Lessee's obligations
under this Lease and such Schedule.

         3.      TERM AND RENTALS: THIS LEASE SHALL BE EFFECTIVE UPON EXECUTION
AND DELIVERY HEREOF by Lessee and Lessor. (a) The Initial Lease Term for each
Schedule shall commence upon the Rent Commencement Date set forth in such
Schedule.  For the Initial Lease Term of such Schedule, Lessee agrees to pay
Lessor aggregate rentals equal to the number of months in the Initial Lease
Term of such Schedule multiplied by the amount of the Rental Payment specified
in such Schedule.  In addition, for the period from the Delivery Date of each
Schedule until such Schedule's Rent Commencement Date, Lessee shall pay an
interim rental ("Interim Rental Payment") equal to the product of (i) the total
rental for the Initial Lease Term of such Schedule divided by 1,260 [42 x 30]
and (ii) the actual number of days between the Delivery Date and the Rent
Commencement Date, including the Delivery Date but excluding the Rent
Commencement Date.  Lessor will make reasonable efforts to se nd Lessee
invoices for Rental Payments, but the failure to do so or the incorrectness of
any invoice will not relieve Lessee of its obligation to pay all amounts,
including Rental Payments, due under this Lease.  The Interim Rental Payment
for each Schedule is due on the Delivery Date for such Schedule and the
remaining Rental Payments are due commencing on the Rent Commencement Date and
thereafter on the same date of each succeeding month of the Term, or as
specified in the applicable Schedule.  A late charge on any overdue payments
shall accrue at the rate of 1.5% per month on the overdue amount, or the
highest lawful rate, whichever is less. (b) The Rent Factor will be calculated
for each Schedule based on a basis point for basis point adjustment (if any) to
the Initial Implicit Rate equal to the change from the Treasury Base Rate in
the U.S. Treasury note rate for notes of a term equal to the Treasury Constant
Maturity as quoted three business days prior to the Delivery Date for such
Schedule in The Wall Street Journal.  The Implicit Rate used for calculating
the Rent Factor for any Schedule shall not be less than the Minimum Implicit
Rate. (c) It is not the intent of the parties to create rent or other payment
obligations of Lessee which will be considered usurious under applicable law.
However, if any such payment shall be found to be usurious by a court of
competent jurisdiction, then Rental Payments or such other amounts shall
automatically be reduced to the highest rate or amounts permitted by applicable
law and the usurious portion of the Rental Payments or such other amounts shall
be applied to the Lessee's remaining obligations under the Lease in a manner
reasonably determined by Lessor.  If Lessee retains possession of any Unit
after the expiration or termination of this



                                       3
   6
Lease, Rental Payments shall continue to be paid with respect to such Unit at
the rate set forth in Section 3(a) of the Schedule relating to such Unit until
all obligations of Lessee under this Lease relating to such Unit, including,
without limitation, Rental Payments and payments due under Section 4 of this
Lease, have been satisfied.  This Lease may be terminated only as expressly
provided herein.

         4.      LESSEE'S PURCHASE OF TENANT IMPROVEMENTS; OPTIONS AT END OF
                 INITIAL LEASE TERM FOR NON-TENANT IMPROVEMENTS:

         4A.     Tenant Improvements.  At the expiration of the Initial Lease
Term of each Schedule covering tenant improvements, Lessee shall purchase all
of the Units that are tenant improvements under such Schedule for a purchase
price equal to fifteen percent (15%) of Lessor's Cost of all such Units, plus
any applicable sales or other transfer tax.

         4B.     Non-Tenant Improvements.

         (a)     Provided that the Lease has not been terminated and that no
Event of Default or event which, with notice or lapse of time or both, would
become an Event of Default shall have occurred and be continuing, Lessee shall
elect one of the following options in clauses (i) or (ii) below:

                 (i)      Lessee's Option to Renew: At the expiration of the
         Initial Lease Term of the first Schedule covering Units other than
         tenant improvements, Lessee may elect to renew the Lease with respect
         to all, but not less than all, of such Units under all Schedules to
         the Lease at their respective expiration dates for not less than
         twelve (12) months nor more than thirty-six (36) months for a rent
         equal to the "Fair Rental Value" (as defined in Section 4B(b) below)
         of such Units for such additional period, but in no event less than
         the Minimum Renewal Percentage of Lessor's Cost of such Units per
         month, which rent shall be paid monthly in advance.  At the end of the
         renewal term, Lessee must purchase all of such Units for a purchase
         price equal to the Fair Market Value (as defined in Section 4B(b)
         below) plus any applicable sales or other transfer tax.

                 (ii)     Lessee's Option to Purchase: At the expiration of the
         Initial Lease Term of the first Schedule covering Units other than
         tenant improvements, Lessee may elect to purchase all, but not less
         than all, of such Units under all Schedules to the Lease at their
         respective expiration dates for a purchase price equal to the "Fair
         Market Value" (as defined in Section 4(b) below) thereof as of the end
         of the Initial Lease Term of the first Schedule covering Units other
         than tenant improvements, but in no event less than the Minimum
         Purchase Option Percentage of Lessor's Cost of all such Units nor
         greater than twenty-five percent (25%) of Lessor's Cost of all such
         Units, plus any applicable sales or other transfer tax.

                 (iii)    If neither of the foregoing options in clauses (i) or
         (ii) of this Section 4B(a) is duly exercised by Lessee, this Lease
         shall be renewed at the rental in effect immediately prior to the
         renewal with respect to all Units other than tenant improvements
         covered by the applicable Schedule from the expiration date of the
         Initial Lease Term of such Schedule on a month-to-month basis.  Lessee
         may terminate any such extended term on 90 days'





                                       4
   7
         notice to Lessor and shall along with such notice elect one of the
         options in clauses (i) or (ii) above.

         Either of the foregoing options in clauses (i) or (ii) shall be
exercised by written notice delivered to Lessor not more than 180 days and not
less than 120 days prior to the expiration of the Initial Lease Tenn of the
Units which are subject to the first Schedule covering Units other than tenant
improvements.

         (b)     Fair Market Value or Fair Rental Value, as the case may be,
shall be determined on the basis of and shall be equal in amount to the value
which would obtain in an arm's-length transaction between an informed and
willing buyer-user or lessee-user (other than a used equipment dealer) and an
informed and willing seller or lessor under no compulsion to sell or lease, on
the assumptions that: such Units (i) are being sold "in place and in use"; (ii)
are free and clear of all liens and encumbrances; and (iii) are in the
condition required upon the return of the Units under Section 9 of this Lease.
In such determination, costs of removal from the location of current use shall
not be a deduction from such value(s).

         (c)     If the Lessor and Lessee have not agreed upon a determination
of the Fair Market Value or Fair Rental Value of any Unit within 30 days after
one of the parties has requested such determination, that determination shall
be made by a certified independent appraiser approved by both Lessor and
Lessee, such approvals not to be unreasonably withheld.  The appraiser shall be
furnished with a letter of instruction concerning the preparation of the
appraisal, together with a copy of the Lease and Schedule and, to the extent
available, related purchase orders and/or invoices.  The appraiser shall be
instructed to make such determination within 30 days following appointment.
The determination made by the appraiser shall be final and binding on both
Lessor and Lessee.  The fees and expenses of any appraisal shall be paid by the
Lessee, if such appraisal is needed for the Lessor's exercise of its remedies
under Sections 12 and 13 hereof, and equally by the Lessor and Lessee
otherwise.

         4C.     General.  The purchase of the Units by Lessee pursuant to this
Section 4 shall be "AS IS, WHERE IS", without recourse to or any warranty by
Lessor, other than a warranty that the Units are free and clear of liens and
encumbrances resulting from acts of Lessor.

         5.      WARRANTIES; INDEMNITY:

         (a)     Lessee acknowledges that it has made the selection of each
Unit based upon its own judgment.  LESSOR MAKES NO EXPRESS OR IMPLIED WARRANTIES
INCLUDING, WITHOUT LIMITATION, THOSE OF DESCRIPTION, INFRINGEMENT,
MERCHANTABILITY OR FITNESS FOR A PARTICULAR USE OR PURPOSE WITH RESPECT TO THE
EQUIPMENT AND HEREBY DISCLAIMS THE SAME.  Lessor shall have no liability for
any damages, whether direct or consequential, incurred by Lessee as a result of
any defect or malfunction of a Unit.  Lessee agrees to look solely to the
manufacturer or vendor of any defective or malfunctioning Unit for the repair
or replacement of such Unit and to continue to make all Rental Payments with
respect to such Unit in spite of such defect or malfunction.  Lessor hereby
assigns to Lessee, for and during the Term, any warranty, guaranty or indemnity
of the manufacturer or vendor issued to Lessor with respect to any Unit.





                                       5

         (b)     Lessee shall indemnify, reimburse and hold Lessor (including,
without limitation, each of its partners) and each of their respective
successors, assigns, officers, directors, shareholders, servants, agents and
employees harmless from and against all liabilities, losses, damages, actions,
suits, demands, claims of any kind and nature (including, without limitation,
claims relating to environmental discharge, cleanup or compliance), and all
costs and expenses whatsoever to the extent they may be incurred or suffered by
such indemnified party in connection therewith (including, without limitation
reasonable attorneys' fees and expenses), fines, penalties (and other charges
of applicable governmental authorities), licensing fees relating to any Unit,
damage to or loss of use of property (including, without limitation,
consequential or special damages to third parties or damages to Lessee's
property), or bodily injury to or death of any person (including, without
limitation, any agent or employee of Lessee) (each a "Claim"), directly or
indirectly relating to or arising out of the acquisition, use, lease or
sublease, ownership, operation, possession, control, storage or condition of
any Unit (regardless of whether such Unit is at the time in the possession of
Lessee), the falsity of any non-tax representation or warranty of Lessee or
Lessee's failure to comply with the terms of the Lease during the Term.  The
foregoing indemnity shall cover, without limitation, (i) any Claim in
connection with a design or other defect (latent or patent) in any Unit, (ii)
any Claim for infringement of any patent, copyright, trademark or other
intellectual property right, (iii) any Claim resulting from the presence on or
under or the escape, seepage, leakage, spillage, discharge, emission or release
from any Unit of any Hazardous Materials, including, without limitation, any
Claims asserted or arising under any Environmental Law, or (iv) any Claim for
negligence or strict or absolute liability in tort; provided, however, that
Lessee shall not indemnify Lessor for any liability incurred by Lessor as a
direct and sole result of Lessor's gross negligence or willful misconduct.
Such indemnities shall continue in full force and effect, notwithstanding the
expiration or termination of this Lease.  Upon Lessor's written demand, Lessee
shall assume and diligently conduct, at its sole cost and expense, the entire
defense of Lessor and its agents, employees, successors and assigns against any
indemnified Claim described in this Section 5. Lessee shall not settle or
compromise any Claim against or involving Lessor without first obtaining
Lessor's written consent thereto, which consent shall not be unreasonably
withheld.

         6.      TITLE, LOCATION AND RETURN: Lessor and Lessee hereby confirm
their intent that the Equipment remain and be deemed personal property and that
title thereto shall remain in Lessor.  If requested by Lessor, Lessee will
affix plates or markings on the Equipment indicating the interests of Lessor.
Lessee may not remove the Equipment from its place of installation without
Lessor's prior written consent, which consent shall not be unreasonably
withheld.  Lessor shall have the right to inspect the Equipment during regular
business hours, with reasonable notice, and in compliance with Lessee's
reasonable security procedures.  If for any reason the Equipment is to be
returned to Lessor on Lessor's demand hereunder, Lessee at its own risk and
expense, will cause the Equipment to be delivered promptly to Lessor free of
all Hazardous Materials and in the same condition as when delivered hereunder,
ordinary wear and tear excepted, to such point in the United States as Lessor
may designate and in such a manner as is consistent with the manufacturer's
recommendations, if any, for transportation and packaging of such Equipment.
All charges to cover Equipment transportation, deinstallation, storage until
returned, packing, and handling and all other costs associated with a return of
the Equipment to the location designated by Lessor shall be paid by Lessee.

interest in, or otherwise transfer all or any part of its rights, title and
interest in this Lease and the Equipment.  Upon Lessor's written notice, Lessee
shall, if requested, pay directly to such assignee without abatement, deduction
or set-off all amounts which become due hereunder.  Lessee waives and agrees it
will not assert against such assignee any counterclaim or set-off in any action
for rent under the Lease.  Such assignee shall have and be entitled to exercise
any and all rights and remedies of Lessor hereunder, and all references herein
to Lessor shall include Lessor's assignee.  Lessee acknowledges that such a
sale, assignment, grant or transfer would neither materially change Lessee's
duties nor materially increase the burdens or risks imposed on the Lessee under
this Lease.  LESSEE MAY NOT, WITHOUT LESSOR'S PRIOR WRITTEN CONSENT, (i)
SUBLEASE, TRANSFER, DISPOSE OF OR ASSIGN ITS RIGHTS IN RESPECT OF ANY UNIT OR
ITS OBLIGATIONS UNDER THIS LEASE OR (ii) ASSIGN, GRANT A SECURITY INTEREST IN,
OR OTHERWISE TRANSFER ALL OR ANY PART OF ITS RIGHTS, TITLE AND INTEREST IN AND
TO THIS LEASE OR THE EQUIPMENT.

         8.      TAXES: Lessee agrees to pay if and when due, in addition to
other amounts due hereunder and under each Schedule, all fees and assessments,
and all sales, use, property, excise and other taxes and charges (including all
interest and penalties) (collectively "Taxes"), now or hereafter imposed by any
governmental body or agency upon any of the Equipment or upon the purchase,
ownership, possession, leasing, operation, use, rentals or other payments, or
disposition hereunder whether payable by Lessor or Lessee (exclusive of taxes
on or measured by Lessor's net income).  Lessee agrees to prepare and file
promptly with the appropriate offices any and all tax and similar returns
required to be filed with respect thereto, or, if requested by Lessor, to
notify Lessor of such requirements and furnish Lessor with all information
required by Lessor so that it may effect such filing, at Lessee's expense.  Any
Taxes paid by or imposed on, Lessor on behalf of Lessee shall become
immediately due and payable on Lessor's demand.  Lessor, as owner, shall be
entitled to any and all depreciation and modified cost recovery deductions
provided under the Internal Revenue Code of 1986, as amended from time to time
and any other such tax benefits which may now or hereafter be available to an
owner of such Equipment (collectively, "Tax Benefits").  If as a result of (i)
the inaccuracy or breach of any of Lessee's representations,, warranties and
covenants herein or in any Schedule, or (ii) the acts or failure to act of
Lessee or any person claiming an interest in the Equipment through the Lessee
(other than a casualty or other event described in Section 11 with respect to
which Stipulated Loss Value shall have been paid by Lessee), Lessor or any of
its assigns shall lose, or shall not, in its reasonable opinion, have the right
to claim, or there shall be disallowed, deferred or recaptured, any portion of
the Tax Benefits with respect to a Unit (a "Loss of Tax Benefits") or there
shall be included in Lessor's gross income any amounts other than Rental
Payments in respect of the purchase price of any Unit (an "Inclusion"), then,
on and after the next succeeding Rent Payment date after written notice to
Lessee by Lessor, Lessee agrees as follows: The rent for the Equipment shall,
on the Rent Payment date next succeeding Lessor's written notice to Lessee of
Lessor's payment of any tax payment attributable to such Inclusion or of a Loss
of Tax Benefits, be increased to such amount or amounts as shall, by the end of
the original term of the last Schedule to this Lease, in the reasonable opinion
of Lessor, after deduction of all fees, taxes, or other charges required to be
paid by Lessor in respect of the receipt of all amounts payable by Lessee to
Lessor under





                                       7
   10
this Section 8 under the laws of any federal, state, or local government or
taxing authority in the United States, cause Lessor's after-tax yield and cash
flow in respect of the Equipment to equal those which would have been realized
by Lessor if Lessor had not incurred such a Loss of Tax Benefits or had such an
Inclusion.  If any claim or contest regarding any tax indemnity covered by this
Section 8 shall arise, such claim or contest shall be addressed or conducted,
at Lessee's expense, in the manner reasonably specified by Lessor.

         9.      USE; MAINTENANCE: (a) Lessee, at its expense, shall make all
necessary site preparations and cause the Equipment to be operated in
accordance with any applicable manufacturer's manuals or instructions.  So long
as no Event of Default has occurred and is continuing, Lessee shall have the
right to quietly possess and use the Equipment as provided herein without
interference by Lessor. (b) Lessee, at its expense, shall maintain the
Equipment in good condition, reasonable wear and tear excepted, and will comply
with all laws, ordinances and regulations to which the use and operation of the
Equipment may be or become subject.  Such obligation shall extend to repair and
replacement of any partial loss or damage to the Equipment, regardless of the
cause.  If maintenance is mandated by the manufacturer, Lessee shall obtain and
keep in effect at all times during the Term maintenance service contracts with
suppliers approved by Lessor, such approval not to be unreasonably withheld.
All parts furnished in connection with such maintenance or repair shall
immediately become part of the Equipment.  All such maintenance, repair and
replacement services shall be paid for and discharged by Lessee when due with
the result that no lien will attach to the Equipment.  Only qualified personnel
of Lessee shall operate the Equipment.  The Equipment shall be used only for
the purposes for which it was designed.

         10.     INSURANCE: (a) Lessee shall obtain and maintain for the Term,
at its own expense, (i) "all risk" insurance against loss or damage to the
Equipment, (ii) commercial general liability insurance (including contractual
liability, products liability and completed operations coverages) reasonably
satisfactory to Lessor, and (iii) such other insurance against such other risks
of loss and with such terms, as shall in each case be reasonably satisfactory
to or reasonably required by Lessor (as to carriers, amounts and otherwise).
(b) The amount of the "all risk" insurance shall be the greater of the
replacement value of the Equipment (as new) or the "Stipulated Loss Value"
specified in the applicable Schedules, which amount shall be determined to
Lessor's reasonable satisfaction as of each anniversary date of this Lease with
the amount so determined being put into effect on the next succeeding renewal
or inception date of such insurance. (c) The deductible with respect to
"all-risk" insurance required by clause (b) above and product liability
insurance required by clause (a) above shall not exceed $25,000; otherwise
there shall be no deductible with respect to any insurance required to be
maintained hereunder. (d) The amount of commercial general liability insurance
(other than products liability coverage and completed operations insurance)
required by clause (a) above shall be at least $2,000,000 per occurrence.  The
amount of the products liability and completed operations insurance required by
clause (a) above shall be at least $2,000,000 per occurrence. (e) Each "all
risk" policy shall: (i) name Lessor as sole loss payee with respect to the
Equipment, (ii) provide for each insurer's waiver of its right of subrogation
against Lessor and Lessee, and (iii) provide that such insurance (A) shall not
be invalidated by any action of Lessee, or any breach by Lessee of any
provision of any of its insurance policies, and (B) shall waive set-off,
counterclaim or offset against Lessor.  Each liability policy shall





                                       8
   11
(w) name Lessor as an additional insured and (x) provide that such insurance
shall have cross-liability and severability of interest endorsements (which
shall not increase the aggregate' policy limits of Lessee's insurance).  All
insurance policies (y) shall provide that Lessee's insurance shall be primary
without a right of contribution of Lessor's insurance, if any, or any
obligation on the part of Lessor to pay premiums of Lessee, and (z) shall
contain a clause requiring the insurer to give Lessor at least 30 days' prior
written notice of its cancellation (other than cancellation for non-payment for
which 10 days' notice shall be sufficient).  Lessee shall on or prior to the
Delivery Date of Schedule No. 1 and prior to each policy renewal, furnish to
Lessor certificates of insurance or other evidence satisfactory to Lessor that
such insurance coverage is in effect.  Lessee further agrees to give Lessor
prompt notice of any damage to, or loss of, the Equipment, or any part thereof.

         11.     LOSS; DAMAGE; DESTRUCTION AND SEIZURE: (a) Lessee shall bear
the risk of the Units being lost, stolen, destroyed, damaged or seized by
governmental authority for any reason whatsoever at any time until the latest
to occur' of (i) the expiration or termination of the Term or (ii) any storage
period thereafter or (iii) the return of the subject Unit to Lessor (if
authorized hereunder), and shall proceed diligently and cooperate fully to
recover any and all damages, insurance proceeds or condemnation awards. (b)
Except as described in Section 11(c) hereof, if during the Term or the storage
period thereafter, any Unit shall be lost, stolen, destroyed, irreparably
damaged or seized by governmental authority for a period equal to at least the
remainder of the Term, Lessor shall receive from the proceeds of insurance
obtained pursuant to Section 10 hereof, from any award paid by the seizing
governmental authority and, to the extent not received from the proceeds of
such insurance or award or both, from Lessee, on or before the Rental Payment
date next succeeding such loss, theft, destruction, damage or governmental
seizure: (i) all accrued and unpaid rent in respect of such Unit including rent
due on the rental payment date next succeeding the date of such loss or seizure
if the rent is in arrears; (ii) the Stipulated Loss Value of such Unit,
determined as of such Rental Payment date; (iii) all other sums, if any, that
shall have become due and payable hereunder; and (iv) interest on the foregoing
at the lower of the rate equal to 1.5% per month or the highest rate then
permitted by applicable law from the due dates(s) of such payment(s) to the
date of payment.  On receipt by Lessor of the amount specified hereinabove with
respect to each such Unit so lost, stolen, destroyed, damaged or seized, (i)
this Lease shall be deemed terminated as to such Unit and rent in respect of
such Unit shall be deemed abated, as of the Rental Payment date next succeeding
such loss, theft, damage, destruction or seizure; and (ii) so long as no
default or Event of Default has occurred and is continuing hereunder, Lessor
shall on demand, transfer title to such Unit, "AS IS, WHERE IS, WITHOUT
RECOURSE, REPRESENTATION OR WARRANTY," to Lessee, or, if appropriate in
Lessor's sole judgment, which judgment shall be exercised in a reasonable
manner, and on prior notice to Lessee, to Lessee's insurance carrier.  Any
proceeds of insurance payable to Lessor pursuant to this Section 11 and Section
10 hereof received by Lessee shall be paid to Lessor promptly upon their
receipt by Lessee.  If any proceeds of insurance or awards received from
governmental authorities are in excess of the amount owed under this Section
11(b), Lessor shall promptly remit to Lessee the amount in excess of the amount
owed to Lessor.  (c) So long as no Event of Default shall have occurred and be
continuing, any proceeds of insurance obtained pursuant to Section 10 hereof
received with respect to any Unit the repair of which is practical shall, at
the election of Lessee, be applied either to the repair of such Unit





                                       9
   12
or, upon Lessor's receipt of evidence of the repair of the Unit reasonably
satisfactory to Lessor, to the reimbursement of Lessee for the cost of such
repair. (d) Lessee shall promptly, but in any event within 30 days thereafter,
notify Lessor in writing in reasonable detail of any loss, theft, destruction
or seizure described in this Section 11. (e) The Stipulated Loss Value payable
by Lessee under this Lease shall be that percentage of Lessor's Cost of the
affected Unit(s) set forth in the table attached to the applicable Schedule as
Annex B opposite the Rental Payment date next following the event giving rise
to Lessee's obligation to pay Stipulated Loss Value.  Stipulated Loss Values
and Rental Payments shall not be prorated.

         12.     EVENTS OF DEFAULT: An "Event of Default" shall occur if
Lessee: (a) fails to pay/make any Rental Payment or other payment required
hereunder when due and such failure continues for a period of 10 days; or (b)
fails to perform or observe any other material covenant, condition or agreement
hereunder or breaches any provision contained herein or in any other document
furnished Lessor in connection herewith, and such failure or breach continues
for a period of 30 days after written notice by Lessor; or (c) makes any
representation or warranty herein or in any document furnished in connection
herewith, which shall have been materially false or inaccurate when made; or
(d) fails to maintain insurance under this Lease or otherwise required by the
Lessor hereunder; or (e) shall admit in writing that it is unable to pay its
debts as they become due, become insolvent or bankrupt or make an assignment
for the benefit of its creditors or consents to the appointment of a trustee or
receiver or insolvency proceedings shall be instituted by or against Lessee.

         13.     REMEDIES: Upon the occurrence of any Event of Default and at
any time thereafter, provided such Event of Default is then continuing (which
occurrence, for purposes of clause (a)(ii)(B) below is the day Lessee shall be
deemed to tender possession of the Equipment to Lessor), (a) Lessor may, in its
discretion, do any one or more of the following, all of which Lessor and Lessee
expressly agree are commercially reasonable under the UCC and any other
applicable law: (i) terminate this Lease; (ii) declare to be immediately due
and payable: (A) all unpaid rent and sums then due and payable under this Lease
(other than amounts payable under clause (B) hereof, if any,) plus (B) an
amount equal to the greater of the then applicable Stipulated Loss Value (which
value Lessee acknowledges has a reasonable discount rate implicit therein) or
the then applicable fair market value of the Equipment as determined by Lessor
(but in no event less than an amount, equal to the Minimum Purchase Option
Percentage of Lessor's Cost); (iii) require that Lessee return all Equipment to
Lessor in accordance with Section 6 hereof, (iv) enter upon the premises where
such Equipment is located and take immediate possession of and remove the same,
all without liability to Lessor or its agents for such entry; (v) sell any or
all of the Equipment at public or private sale, with or without notice to
Lessee or advertisement, or otherwise dispose of, hold, use, operate, lease to
others or keep idle such Equipment, all free and clear of any rights of Lessee
and without any duty to account to Lessee for such action or inaction or for
any proceeds with respect thereto subject to applicable law; (vi) exercise any
other right or remedy which may be available under the UCC or other applicable
law including the right to recover damages for the breach hereof. (b) In
addition, Lessee shall be liable for, and reimburse Lessor for, all reasonable
and necessary attorneys' fees and other expenses incurred by Lessor as a result
of the foregoing defaults, or the exercise of Lessor's remedies, including
without limitation placing any Equipment in the condition required by Section 9
hereof.  No remedy referred to





                                       10
   13
in this Section 13 is intended to be exclusive, but each shall be cumulative
and in addition to any other remedy referred to above or otherwise available to
Lessor at law or in equity (c) There shall be no waiver by Lessor of any
default unless in writing and such waiver shall not constitute a waiver of any
other default by Lessee, or a waiver of any of Lessor's other rights.  Lessee
waives any rights now or hereafter conferred by statute or otherwise that may
require Lessor to sell, re-lease or otherwise use or dispose any Unit in
mitigation of the Lessor's damages or that might otherwise limit or modify any
of Lessor's rights or remedies under this Lease.

         14.     LESSEE'S REPRESENTATIONS, WARRANTIES AND COVENANTS:  (a) Lessee
warrants and represents the following as of the date hereof.  (i) Lessee is a
corporation duly organized, validly existing and in good standing under the laws

against Lessee or any of its subsidiaries before any court or administrative
agency which might have a materially adverse effect on the business, condition
or operations of Lessee or such subsidiary; and (iv) this Lease has been and
each Schedule will be duly executed and delivered by Lessee and constitute or
will constitute the valid, binding and enforceable obligations of Lessee. (b)

Schedule: (i) all of the Units being delivered on the Delivery Date of such

                       Conditions to Lessor's Obligations


         By their initials below and on the signature page of the Master

Lessor and Lessee agree that the Lease incorporates the following terms:

         1.      On or prior to the date of execution of the Lease by Lessor,

         THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
         AS AMENDED, OR ANY STATE SECURITIES LAWS.  NO SALE OR DISPOSITION MAY
         BE EFFECTED WITHOUT (i) EFFECTIVE REGISTRATION STATEMENTS RELATED

                         CALYPTE BIOMEDICAL CORPORATION

                       WARRANT TO PURCHASE 122,667 SHARES
                                OF COMMON STOCK


         THIS CERTIFIES THAT, for value received, MMC/GATX Partnership No. I
(the "Partnership") is entitled to subscribe for and purchase 122,667 shares of
the fully paid and nonassessable Common Stock, $.001 par value (as adjusted
pursuant to Section 4 hereof, the "Shares") of Calypte Biomedical Corporation,
a California corporation (the "Company"), at the price of $.75 per share (such
price and such other price as shall result, from time to time, from the
adjustments specified in Section 4 hereof is herein referred to as the "Warrant
Price"), subject to the provisions and upon the terms and conditions
hereinafter set forth.  As used herein, (a) the term "Common Stock" shall mean
the Company's presently authorized Common Stock, and any stock into or for
which such Common Stock may hereafter be converted or exchanged, (b) the term
"Date of Grant" shall mean August 20, 1993, and (c) the term "Other Warrants"
shall mean any other warrants issued by the Company in connection with the
transaction with respect to which this Warrant was issued, and any warrant
issued upon transfer or partial exercise of this Warrant.  The term "Warrant"
as used herein shall be deemed to include Other Warrants unless the context
clearly requires otherwise.

         1.      Term.  The purchase right represented by this Warrant is
exercisable, in whole or in part, at any time and from time to time from the
Date of Grant through the later of (i) ten (10) years after the Date of Grant
or (ii) five (5) years after the closing of the Company's initial public
offering of its Common Stock effected pursuant to a Registration Statement on
Form S-1 (or its successor) filed under the Securities Act of 1933, as amended
(the "Act").

         2.      Method of Exercise, Payment, Issuance of New Warrant.  Subject
to Section 1 hereof, the purchase right represented by this Warrant may be
exercised by the holder hereof, in whole or in part and from time to time, by
either, at the election of the holder hereof, (a) the surrender of this Warrant
(with the notice of exercise form attached hereto as Exhibit A duly executed)
at the principal office of the Company and by the payment to the Company, by
   21

check, of an amount equal to the then applicable Warrant Price multiplied by the
number of Shares then being purchased, or (b) if in connection with a registered
public offering of the Company's securities, the surrender of this Warrant (with
the notice of exercise form attached hereto as Exhibit A-1 duly executed) at the
principal office of the Company together with notice of arrangements reasonably
satisfactory to the Company for payment to the Company either by check or from
the proceeds of the sale of shares to be sold by the holder in such public
offering of an amount equal to the then applicable Warrant Price per share
multiplied by the number of Shares then being purchased.  The person or persons
in whose name(s) any certificate(s) representing shares of Common Stock shall be
issuable upon exercise of this Warrant shall be deemed to have become the
holder(s) of record of, and shall be treated for all purposes as the record
holder(s) of, the shares represented thereby (and such shares shall be deemed to
have been issued) immediately prior to the close of business on the date or
dates upon which this Warrant is exercised.  In the event of any exercise of the
rights represented by this Warrant, certificates for the shares of stock so
purchased shall be delivered to the holder hereof as soon as possible and in any
event within thirty days after such exercise and, unless this Warrant has been
fully exercised or expired, a new Warrant representing the portion of the
Shares, if any, with respect to which this Warrant shall not then have been
exercised shall also be issued to the holder hereof as soon as possible and in
any event within such thirty-day period.

         3.      Stock Fully Paid; Reservation of Shares.  All Shares that may
be issued upon the exercise of the rights represented by this Warrant will,
upon issuance pursuant to the terms and conditions herein, be fully paid and
nonassessable, and free from all taxes, liens and charges with respect to the
issue thereof.  During the period within which the rights represented by this
Warrant may be exercised, the Company will at all times have authorized, and
reserved for the purpose of the issue upon exercise of the purchase rights
evidenced by this Warrant, a sufficient number of shares of its Common Stock to
provide for the exercise of the rights represented by this Warrant.

         4.      Adjustment of Warrant Price and Number of Shares.  The number
and kind of securities purchasable upon the exercise of this Warrant and the
Warrant Price shall be subject to adjustment from time to time upon the
occurrence of certain events, as follows:

         (a)     Reclassification or Merger.  In case of any reclassification,
change or conversion of securities of the class issuable upon exercise of this
Warrant (other than a change in par value, or from par value to no par value, or
from no par value to par value, or as a result of a subdivision or combination),
or in case of any merger of the Company with or into another corporation (other
than a merger with another corporation in which the Company is the acquiring and
the surviving corporation and which does not result in any reclassification or
change of outstanding securities issuable upon exercise of this Warrant), or in
case of any sale of all or substantially all of the assets of the Company, the
Company, or such successor or purchasing corporation, as the case may be, shall
duly execute and deliver to the holder of this Warrant a new Warrant (in form
and substance satisfactory to the holder of this Warrant), so that the holder of
this Warrant shall have the right to receive, at a total purchase price not




                                       2
   22
to exceed that payable upon the exercise of the unexercised portion of this
Warrant, and in lieu of the shares of Common Stock theretofore issuable upon
exercise of this Warrant, the kind and amount of shares of stock, other
securities, money and property receivable upon such reclassification, change or
merger by a holder of the number of shares of Common Stock then purchasable
under this Warrant.  Such new Warrant shall provide for adjustments that shall
be as nearly equivalent as may be practicable to the adjustments provided for
in this Section 4. The provisions of this subparagraph (a) shall similarly
apply to successive reclassifications, changes, mergers and transfers.

                 (b)      Subdivision or Combination of Shares.  If the Company
at any time while this Warrant remains outstanding and unexpired shall
subdivide or combine its outstanding shares of Common Stock, the Warrant Price
shall be proportionately decreased in the case of a subdivision or increased in
the case of a combination, effective at the close of business on the date the
subdivision or combination becomes effective.

                 (c)      Stock Dividends and Other Distributions.  If the
Company at any time while this Warrant is outstanding and unexpired shall (i)
pay a dividend with respect to Common Stock payable in Common Stock, or (ii)
make any other distribution with respect to Common Stock (except any
distribution specifically provided for in the foregoing subparagraphs (a) and
(b)) of Common Stock, then the Warrant Price shall be adjusted, from and after
the date of determination of shareholders entitled to receive such dividend or
distribution, to that price determined by multiplying the Warrant Price in
effect immediately prior to such date of determination by a fraction (i) the
numerator of which shall be the total number of shares of Common Stock
outstanding immediately prior to such dividend or distribution, and (ii) the
denominator of which shall be the total number of shares of Common Stock
outstanding immediately after such dividend or distribution.

                 (d)       Adjustment of Number of Shares.  Upon each
adjustment in the Warrant Price, the number of Shares of Common Stock
purchasable hereunder shall be adjusted, to the nearest whole share, to the
product obtained by multiplying the number of Shares purchasable immediately
prior to such adjustment in the Warrant Price by a fraction, the numerator of
which shall be the Warrant Price immediately prior to such adjustment and the
denominator of which shall be the Warrant Price immediately thereafter.

                 (e)      Antidilution Rights.  In the event that the
"Conversion Price" (as defined in the Company's Restated Articles of
Incorporation, as amended through the Date of Grant, a true and complete copy
of which is attached hereto as Exhibit B (the "Charter")), for the Company's
Series D Preferred Stock is reduced from time to time prior to December 16,
1993 pursuant to the antidilution rights applicable to the Series D Preferred
Stock set forth in Section 6.C.(a)(i)(I) of Article III of the Charter (other
than reductions covered by Sections 4(b) or (c) of this Warrant), then the same
reduction shall forthwith be made to the Warrant Price, subject to
proportionate adjustment to reflect any stock split or combination, stock
dividend or similar event occurring after the Date of Grant.  The intent of
this Section 4(e) is to provide the holder of this Warrant with the same
antidilution protection as would have





                                       3
   23
prevailed prior to December 16, 1993 if this Warrant had entitled the holder
hereof to purchase shares of the Company's Series D Preferred Stock (rather
than Common Stock), as such antidilution protection is set forth in the
Charter.  Such antidilution rights shall not be amended, modified or waived in
any manner that is materially adverse to the holder hereof without such
holder's prior written consent.  The Company shall promptly provide the holder
hereof with any restatement, amendment, modification or waiver of the Charter
promptly after the same has been made.

         5.      Notice of Adjustments.  Whenever the Warrant Price or the
number of Shares purchasable hereunder shall be adjusted pursuant to Section 4
hereof, the Company shall make a certificate signed by its chief financial
officer setting forth, in reasonable detail, the event requiring the
adjustment, the amount of the adjustment, the method by which such adjustment
was calculated, and the Warrant Price and the number of Shares purchasable
hereunder after giving effect to such adjustment, which shall be mailed
(without regard to Section 13 hereof, by first class mail, postage prepaid) to
the holder of this Warrant.

         6.      Fractional Shares.  No fractional shares of Common Stock will
be issued in connection with any exercise hereunder, but in lieu of such
fractional shares the Company shall make a cash payment therefor based on the
fair market value of the Common Stock on the date of exercise as reasonably
determined in good faith by the Company's Board of Directors.

         7.      Compliance with Securities Act, Disposition of Warrant or
                 Shares of Common Stock.

                 (a) Compliance with Securities Act.  The holder of this
Warrant, by accept agrees that this Warrant, and the shares of Common Stock to
be issued upon exercise hereof are being acquired for investment and that such
holder will not offer, sell or otherwise dispose of this Warrant, or any shares
of Common Stock to be issued upon exercise hereof except under circumstances
which will not result in a violation of the Act.  Upon exercise of this
Warrant, unless the Shares being acquired are registered under the Act or an
exemption from such registration is available, the holder hereof shall confirm
in writing, by executing the form attached as Schedule 1 to Exhibit A hereto,
that the shares of Common Stock so purchased are being acquired for investment
and not with a view toward distribution or resale.  This Warrant and all shares
of Common Stock issued upon exercise of this Warrant (unless registered under
the Act) shall be stamped or imprinted with a legend in substantially the
following form:

         "THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS.  NO
         SALE OR DISPOSITION MAY BE EFFECTED WITHOUT (i) EFFECTIVE REGISTRATION
         STATEMENTS RELATED THERETO, (ii) AN OPINION OF COUNSEL FOR THE HOLDER,
         REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH RE-





                                       4
   24
         GISTRATIONS ARE NOT REQUIRED, (iii) RECEIPT OF NO-ACTION LETTERS FROM
         THE APPROPRIATE GOVERNMENTAL AUTHORITIES, OR (iv) OTHERWISE COMPLYING
         WITH THE PROVISIONS OF SECTION 7 OF THE WARRANT UNDER WHICH THESE
         SECURITIES WERE ISSUED, DIRECTLY OR INDIRECTLY."

         In addition, in connection with the issuance of this Warrant, the
holder specifically represents to the Company by acceptance of this Warrant as
follows:

         (1)     The holder is aware of the Company's business affairs and
financial condition, and has acquired information about the Company sufficient
to reach an informed and knowledgeable decision to acquire this Warrant.  The
holder is acquiring this Warrant for its own account for investment purposes
only and not with a view to, or for the resale in connection with, any
"distribution" thereof for purposes of the Act.

         (2)     The holder understands that this Warrant has not been
registered under the Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of the
holder's investment intent as, expressed herein.  In this connection, the
holder understands that, in the view of the SEC, the statutory basis for such
exemption may be unavailable if the holder's representation was predicated
solely upon a present intention to hold the Warrant for the minimum capital
gains period specified under tax statutes, for a deferred sale, for or until an
increase or decrease in the market price of the Warrant, or for a period of one
year or any other fixed period in the future.

         (3)     The holder further understands that this Warrant must be held
indefinitely unless subsequently registered under the Act and any applicable
state securities laws, or unless exemptions from registration are otherwise
available.  Moreover, the holder understands that, except as provided in
Section 9 hereof, the Company is under no obligation to register this Warrant.

         (4)     The holder is aware of the provisions of Rule 144 and 144A,
promulgated under the Act, which, in substance, permit limited public resale of
"restricted securities" acquired, directly or indirectly, from the issuer
thereof (or from an affiliate of such issuer), in a non-public offering subject
to the satisfaction of certain conditions, if applicable, including, among
other things: The availability of certain public information about the Company,
the resale occurring not less than two years after the party has purchased and
paid for the securities to be sold; the sale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934, as
amended) and the amount of securities being sold during any three-month period
not exceeding the specified limitations stated therein.

         (5)     The holder further understands that at the time it wishes to
sell this Warrant there may be no public market upon which to make such a sale,
and that, even if such a public market then exists, the Company may not be
satisfying the current public information re-





                                       5
   25
quirements of Rule 144 and 144A, and that, in such event, the holder may be
precluded from selling this Warrant under Rule 144 and 144A even if the
two-year minimum holding period had been satisfied.

         (6)     The holder further understands that in the event all of the
requirements of Rule 144 and 144A are not satisfied, registration under the
Act, compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rule 144 and 144A are not
exclusive, the Staff of the SEC has expressed its opinion that persons
proposing to sell private placement securities other than in a registered
offering and otherwise than pursuant to Rule 144 and 144A will have a
substantial burden of proof in establishing that an exemption from registration
is available for such offers or sales, and that such persons and their
respective brokers who participate in such transactions do so at their own
risk.

                 (b)      Disposition of Warrant or Shares.  With respect to
any offer, sale or other disposition of this Warrant or any shares of Common
Stock acquired pursuant to the exercise of this Warrant prior to registration
of such Warrant or shares, the holder hereof and each subsequent holder of this
Warrant agrees to give written notice to the Company prior thereto, describing
briefly the manner thereof, together with a written opinion of such holder's
counsel, if reasonably requested by the Company, to the effect that such offer,
sale or other disposition may be effected without registration or qualification
(under the Act as then in effect or any federal or state law then in effect) of
this Warrant or such shares of Common Stock and indicating whether or not under
the Act certificates for this Warrant or such shares of Common Stock to be sold
or otherwise disposed of require any restrictive legend as to applicable
restrictions on transferability in order to ensure compliance with such law.
Promptly upon receiving such written notice and reasonably satisfactory
opinion, if so requested, the Company, as promptly as practicable, shall notify
such holder that such holder may sell or otherwise dispose of this Warrant or
such shares of Common Stock, all in accordance with the terms of the notice
delivered to the Company.  If a determination has been made pursuant to this
subsection (b) that the opinion of counsel for the holder is not reasonably
satisfactory to the Company, the Company shall so notify the holder promptly
after such determination has been made and shall specify in detail the legal
analysis supporting any such conclusion.  Notwithstanding the foregoing, this
Warrant or such shares of Common Stock may, as to such federal laws, be
offered, sold or otherwise disposed of in accordance with Rule 144 or 144A
under the Act, provided that the Company shall have been furnished with such.
information as the Company may reasonably request to provide a reasonable
assurance that the provisions of Rule 144 or 144A have been satisfied.  Each
certificate representing this Warrant or the shares of Common Stock thus
transferred (except a transfer pursuant to Rule 144 or 144A) shall bear a
legend as to the applicable restrictions on transferability in order to ensure
compliance with such laws, unless in the aforesaid opinion of counsel for the
holder, such legend is not required in order to ensure compliance with such
laws.  The Company may issue stop transfer instructions to its transfer agent
in connection with such restrictions.





                                       6
   26
         (c)     Excepted Transfers.  Neither any restrictions of any legend
described in this Warrant nor the requirements of Section 7(b) above shall
apply to any transfer without any additional consideration of, or grant of a
security interest in, this Warrant or any part hereof (i) to a partner of the
holder if the holder is a partnership, (ii) by the holder to a partnership of
which the holder is a general partner, or (iii) to any affiliate of the holder
if the holder is a corporation; provided, however, in any such transfer, the
transferee shall on the Company's request agree in writing to be bound by the
terms of this Warrant as if an original signatory hereto.

         8.      Rights as Shareholders, Information.  No holder of this
Warrant, as such, shall be entitled to vote or receive dividends or be deemed
the holder of Common Stock or any other securities of the Company which may at
any time be issuable on the exercise hereof for any purpose, nor shall anything
contained herein be construed to confer upon the holder of this Warrant, as
such, any of the rights of a shareholder of the Company or any right to vote
for the election of directors or upon any matter submitted to shareholders at
any meeting thereof, or to receive notice of meetings, or to receive dividends
or subscription rights or otherwise until this Warrant shall have been
exercised and the Shares purchasable upon the exercise hereof shall have become
deliverable, as provided herein.  Notwithstanding the foregoing, the Company
will transmit to the holder of this Warrant such information, documents and
reports as are generally distributed to the holders of any class or series of
the securities of the Company concurrently with the distribution thereof to the
shareholders.

         9.      Registration Rights.  The Company covenants and agrees as
follows:

                 9.1      Definitions.  For purposes of this Section 9:

                 (a)      The term "Registrable Shares" means (i) the Common
Stock issuable or issued upon exercise or conversion of this Warrant or upon
exercise or conversion of the Other Warrants, and (ii) any Common Stock of the
Company issued as (or issuable upon the conversion or exercise of any warrant,
right or other security which is issued as) a dividend or other distribution
with respect to, or in exchange for or in replacement of, such Series Common
Stock;

                 (b)      The term "Shareholder" means any person owning or
having the right to acquire Registrable Shares or any assignee thereof in
accordance with Paragraph 9.3 hereof; and

                 (c)      The term "Registration Rights" means Section 9 (other
than Sections 9.1, 9.3 and 9.4) of the Agreement for the Purchase and Sale of
Series D Preferred Stock dated as of December 16, 1992 by and among the Company
and the investors who are signatories thereto (the "Purchase Agreement").

                 9.2      Grant of Rights.  The Company hereby grants to the
Shareholders the rights set forth in the Registration Rights.  A true and
complete copy of the Registration





                                       7
   27
Rights is attached hereto as Exhibit C. The Company represents and warrants to
the Shareholders that the Company has obtained all consents of parties to the
Purchase Agreement and of any other persons that are required in order for the
Registrable Shares to be included in the definition of "Registrable Securities"
and for the Shareholders to be included in the definition of "Holders," as such
terms are used in the Registration Rights.

                 9.3      Assignment of Registration Rights.  Notwithstanding
any provision of the Registration Rights, the rights to cause the Company to
register Registrable Shares pursuant to the Registration Rights and this
Section 9 may be assigned by a Shareholder to a transferee or assignee of such
securities provided the Company is, within a reasonable time after such
transfer, furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are being assigned; and provided, further, that such
assignment shall be effective only if immediately following such transfer the
further disposition of such securities by the transferee or assignee is
restricted under the Act.

                 9.4      No Conflicting Agreements.  The Company represents
and warrants to the Shareholders that the Company is not a party to any
agreement that conflicts in any manner with the Shareholders' rights to cause
the Company to register Registrable Shares pursuant to the Registration Rights
and this Section 9. The Company covenants and agrees that it shall not, without
the prior written consent of the Shareholders holding a majority of the
outstanding Registrable Shares, amend, modify or restate the Registration
Rights if the rights of the Shareholders would be subordinated, diminished or
otherwise adversely affected in a different manner than other "Holders" of
"Registrable Securities" (as defined in the Registration Rights).

                 9.5      Rights and Obligations Survive Exercise and
Expiration of Warrant.  The rights and obligations of the Company, of the
holder of this Warrant and of the Registrable Shares contained in the
Registration Rights and this Section 9 shall survive exercise, conversion and
expiration of this Warrant.

         10.     Additional Rights.

                 10.1     Secondary Sales.  The Company agrees that it will not
interfere with the holder of this Warrant in obtaining liquidity if
opportunities to make secondary sales of the Company's securities become
available.  To this end, the Company will promptly provide the holder of this
Warrant with the same notice (if any) as it provides to other holders of the
Company's securities of any offer to acquire from the Company's security
holders more than five percent (5%) of the total voting power of the Company
and will not interfere with the holder in arranging the sale of this Warrant to
the person or persons making such offer.

                 10.2     Mergers.  The Company will provide the holder of this
Warrant with at least 30 days' notice of the terms and conditions of any
proposed (i) sale, lease, exchange, conveyance or other disposition of all or
substantially all of its property or business, or (ii)





                                       8
   28
merger into or consolidation with any other corporation (other than a
wholly-owned subsidiary of the Company), or any other transaction (including a
merger or other reorganization) or series of related transactions, in which
more than 50% of the voting power of the Company is disposed of.

                 10.3     Right to Convert Warrant into Common Stock: Net
Issuance.

                          (a)     Right to Convert.  In addition to and without
limiting the rights of the holder under the terms of this Warrant, the holder
shall have the right to convert this Warrant or any portion thereof (the
"Conversion Right") into shares of Common Stock as provided in this Section
10.3 at any time or from time to time during the term of this Warrant.  Upon
exercise of the Conversion Right with respect to a particular number of shares
subject to this Warrant (the "Converted Warrant Shares"), the Company shall
deliver to the holder (without payment by the holder of any exercise price or
any cash or other consideration) (X) that number of shares of fully paid and
nonassessable Common Stock equal to the quotient obtained by dividing the value
of this Warrant (or the specified portion hereof) on the Conversion Date (as
defined in subsection (b) hereof), which value shall be determined by
subtracting (A) the aggregate Warrant Price of the Converted Warrant Shares
immediately prior to the exercise of the Conversion Right from (B) the
aggregate fair market value of the Converted Warrant Shares issuable upon
exercise of this Warrant (or the specified portion hereof) on the Conversion
Date (as herein defined) by (Y) the fair market value of one share of Common
Stock on the Conversion Date (as herein defined).

         Expressed as a formula, such conversion shall be computed as follows:

         X =   B - A
               -----
                 Y

 Where:        X  = the number of shares Common Stock that may be issued 
                    to holder

               Y  = the fair market value (FMV) of one share of Common Stock

               A  = the aggregate Warrant Price (i.e., Converted Warrant 
                    Shares x Warrant Price)

               B  = the aggregate FMV (i.e., FMV x Converted Warrant Shares)

         No fractional shares shall be issuable upon exercise of the Conversion
Right, and, if the number of shares to be issued determined in accordance with
the foregoing formula is other than a whole number, the Company shall pay to
the holder an amount in cash equal to the fair market value of the resulting
fractional share on the Conversion Date (as hereinafter defined).

   29
                          (b)     Method of Exercise.  The Conversion Right may
be exercised by the holder by the surrender of this Warrant at the principal
office of the Company together with a written statement specifying that the
holder thereby intends to exercise the Conversion Right and indicating the
number of shares subject to this Warrant which are being surrendered (referred
to in subsection (a) hereof as the Converted Warrant Shares) in exercise of the
Conversion Right.  Such conversion shall be effective upon receipt by the
Company of this Warrant together with the aforesaid written statement, or on
such later date as is specified therein (the "Conversion Date"), and, at the
election of the holder hereof, may be made contingent upon the closing of the
sale of the Company's Common Stock to the public in a public offering pursuant
to a Registration Statement under the Act (a "Public Offering").  Certificates
for the shares issuable upon exercise of the Conversion Right and, if
applicable, a new warrant evidencing the balance of the shares remaining
subject to this Warrant, shall be issued as of the Conversion Date and shall be
delivered to the holder within thirty (30) days following the Conversion Date.

                          (c)     Determination of Fair Market Value.  For
purposes of this Section 10.3, "fair market value" of a share of Common Stock
as of a particular date (the "Determination Date") shall mean:

                 (i)      If the Conversion Right is exercised in connection
with and contingent upon a Public Offering, and if the Company's Registration
Statement relating to such Public Offering ("Registration Statement") has been
declared effective by the SEC, then the initial "Price to Public" specified in
the final prospectus with respect to such offering.

                 (ii)     If the Conversion Right is not exercised in
connection with and contingent upon a Public Offering, then as follows:

                 (A)      If traded on a securities exchange, the fair market
         value of the Common Stock shall be deemed to be the average of the
         closing prices of the Common Stock on such exchange over the 30-day
         period ending five business days prior to the Determination Date;

                 (B)      If traded over-the-counter, the fair market value of
         the Common Stock shall be deemed to be the average of the closing bid
         prices of the Common Stock over the 30-day period ending five business
         days prior to the Determination Date; and

                 (C)      If there is no public market for the Common Stock,
         then fair market value shall be determined by mutual agreement of the
         holder of this Warrant and the Company, and if the holder and the
         Company are unable to so agree, by an investment banker of national
         reputation selected by the Company and reasonably acceptable to the
         holder of this Warrant.  The fees and expenses of any such investment
         banker shall be borne equally by the Company and the holder of this
         Warrant.

                 (d)      The execution and delivery of this Warrant are not,

hereof may be changed, waived, discharged or terminated only by an instrument

right to registration of the shares of Registrable Securities) to which the
holder hereof shall continue to be entitled after such exercise or conversion

the holder hereof that, upon receipt of evidence reasonably satisfactory to the
Company of the loss, theft, destruction or mutilation of this Warrant or any

                      INVESTMENT REPRESENTATION STATEMENT


Purchaser:

Company:         Calypte Biomedical Corporation

Security:        Common Stock

Amount:

Date:

         In connection with the purchase of the above-listed securities (the
"Securities"), the undersigned (the "Purchaser") represents to the Company as
follows:

         (a)     The Purchaser is aware of the Company's business affairs and
financial condition, and has acquired sufficient information about the Company
to reach an informed and knowledgeable decision to acquire the Securities.  The
Purchaser is purchasing the Securities for its own account for investment
purposes only and not with a view to, or for the resale in connection with, any
"distribution" thereof for purposes of the Securities Act of 1933, as amended
(the "Act").

         (b)     The Purchaser understands that the Securities have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of the Purchaser's investment intent as expressed herein.  In this
connection, the Purchaser understands that, in the view of the Securities and
Exchange Commission ("SEC"), the statutory basis for such exemption may be
unavailable if the Purchaser's representation was predicated solely upon a
present intention to hold these Securities for the minimum capital gains period
specified under tax statutes, for a deferred sale, for or until an increase or
decrease in the market price of the Securities, or for a period of one year or
any other fixed period in the future.

         (c)     The Purchaser further understands that the Securities must be
held indefinitely unless subsequently registered under the Act or unless an
exemption from registration is otherwise available.  Moreover, the Purchaser
understands that the Company is under no obligation to register the Securities
except as set forth in the Warrant under which the Securities are being
acquired.  In addition, the Purchaser understands that the certificate
evidencing the Securities will be imprinted with the legend referred to in the
Warrant under which the Securities are being purchased.

         (d)     The Purchaser is aware of the provisions of Rule 144 and 144A,
promulgated under the Act, which, in substance, permit limited public resale of
"restricted securities"





                                       16
   36
acquired, directly or indirectly, from the issuer thereof (or from an affiliate
of such issuer), in a non-public offering subject to the satisfaction of
certain conditions, if applicable, including, among other things: The
availability of certain public information about the Company, the resale
occurring not less than two years after the party has purchased and paid for
the securities to be sold; the sale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934, as
amended) and the amount of securities being sold during any three-month period
not exceeding the specified limitations stated therein.

         (e)     The Purchaser further understands that at the time it wishes
to sell the Securities there may be no public market upon which to make such a
sale, and that, even if such a public market then exists, the Company may not
be satisfying the current public information requirements of Rule 144 and 144A,
and that, in such event, the Purchaser may be precluded from selling the
Securities under Rule 144 and 144A even if the two-year minimum holding period
had been satisfied.

         (f)     The Purchaser further understands that in the event all of the
requirements of Rule 144 and 144A are not satisfied, registration under the
Act, compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rule 144 is not exclusive,
the Staff of the SEC has expressed its opinion that persons proposing to sell
private placement securities other than in a registered offering and otherwise
than pursuant to Rule 144 will have a substantial burden of proof in
establishing that an exemption from registration is available for such offers
or sales, and that such persons and their respective brokers who participate in
such transactions do so at their own risk.

                                           Purchaser:

                                           
                                           ------------------------------------

                                           Date:                       199

   59

                       SECURITY DEPOSIT PLEDGE AGREEMENT


         AGREEMENT made and entered into as of August 20, 1993, by and between
Calypte Biomedical Corporation, a California corporation, with a principal
place of business at 1440 Fourth Street, Berkeley, CA 94710 ("Pledgor") and
MMC/GATX Partnership No. I, a California general partnership, with its place of
business at c/o GATX Capital Corporation, Four Embarcadero Center, San
Francisco, CA 94111, as Agent (the "Agent" or "Pledgee").


                                   WITNESSETH

         In consideration of, and as an inducement for Pledgee (i) to enter
into and advance funds under the Equipment Lease Agreement, dated as of August.
20, 1993 (as amended from time to time, the "Lease"), with Pledgor and one or
more Schedules in connection with the Lease (the "Schedules"), and (ii) to
secure the payment of rentals and performance of all Pledgor's other
obligations under this Agreement, the Lease and all exhibits and Schedules
thereto (collectively, the "Obligations"), Pledgor shall deposit and pledge
with Pledgee, on the Delivery Date of each Schedule, a cash collateral security
deposit (the "Security Deposit") in the amount of six percent (6%) of Lessor's
Cost under such Schedule (such terms and other terms not otherwise defined
herein having the meaning therefor as set forth in the Lease or the Schedules).

         NOW THEREFORE, it is agreed:

         1.      Delivery of Deposit; Earnings.  Pledgor shall, on or before
the Delivery Date of each Schedule, deliver the Security Deposit for such
Schedule to Pledgee to secure the due and punctual payment and performance of
the Obligations.  Pledgor will receive simple interest on the Security Deposit
at a rate equal to four and one-half percent (4.5%) per annum (the
"Earnings"), such Earnings to be paid to Pledgor when and if the Security
Deposit is returned to Pledgor in accordance with the terms hereof.  The Agent
may commingle the Security Deposit and Earnings with its own funds or funds of
the Pledgee or otherwise deposit such Security Deposit in any bank selected by
Pledgee.

         2.      Grant of Security.  All funds held by the Pledgee,
representing the Security Deposit and any Earnings, shall constitute collateral
security for the performance by Pledgor of all its Obligations.  Accordingly,
Pledgor assigns, delivers, pledges and conveys to Pledgee, and grants to
Pledgee a first priority, perfected security interest in and to the Security
Deposit and all Earnings for the prompt and unconditional fulfillment of the
Obligations.



                                       1
   60
         3.      Deposit Defaults.  If any default or Event of Default under
the Lease (each being a "Deposit Default") by Pledgor shall occur and be
continuing, earnings accrued on the Security Deposit for Pledgor's benefit
shall cease on notice of such Deposit Default to Pledgor.  Pledgee may
thereupon apply the Security Deposit and any Earnings (accrued to the date of
such default notice), in such manner as Pledgee reasonably determines, towards
the satisfaction of the Obligations, including the payment of all costs and
expenses incurred by Pledgee as a result of any Deposit Default.

4.      Enforcement.  Pledgee shall have no duty to commence an action against
or seek recourse from Pledgor in the event of a Deposit Default first before
enforcing the provisions of this Agreement.  The Obligations of Pledgor
shall be absolute and unconditional, and shall remain in force and effect
without regard to, and shall not be released or discharged or in any way
affected by:

                 (a)      any amendment or modification of or supplement to
the Lease or any exhibit or Schedule thereto, or to this Agreement;

                 (b)      any exercise or non-exercise of any right, remedy or
privilege under or in respect to this Agreement, the Lease or any exhibit or
Schedule thereto, or any other instrument provided for in any thereof, or any
waiver, consent, indulgence or actions or inaction with respect to any such
instrument;

                 (c)      any bankruptcy, insolvency, reorganization,
arrangement, readjustment, composition, liquidation or similar proceeding of or
against Pledgor; or

                 (d)      any payment received by Pledgee and subsequently
refunded or returned to Pledgor or anyone on behalf of Pledgor.

         5.      Return of Security Deposit.  So long as no Event of Default
shall have occurred and be continuing under the Lease, at the end of the Term
of each Schedule, the Security Deposit with respect to such Schedule shall be
applied first to Pledgor's end-of-Term obligations to Pledgee with respect to
such Schedule, and the balance (if any) of such Security Deposit with respect
to such Schedule and Earnings attributable thereto (less any portion thereof
applied or otherwise utilized pursuant to this Agreement) shall be delivered to
Pledgor.

         6.      Further Assurances.  Pledgor will promptly execute and deliver
to Pledgee such further reasonable documents and take such further reasonable
action as Pledgee may request in order to more effectively carry out the intent
and purpose of this Agreement or an assignment of Pledgee's interest herein.

         7.      Notices.  Notices required or permitted hereunder shall be
given in accordance with the Lease.



                                       2
   61
         8.      Amendments and Supplements.  No agreement shall be effective
to amend, supplement or discharge this Agreement in whole or in part unless

                       SECURITY DEPOSIT PLEDGE AGREEMENT


         AGREEMENT made and entered into as of August 20, 1993, by and between
Calypte Biomedical Corporation, a California corporation, with a principal
place of business at 1440 Fourth Street, Berkeley, CA 94710 ("Pledgor") and
MMC/GATX Partnership No. I, a California general partnership, with its place of
business at c/o GATX Capital Corporation, Four Embarcadero Center, San
Francisco, CA 94111, as Agent (the "Agent" or "Pledgee").


                                   WITNESSETH

       In consideration of, and as an inducement for Pledgee (i) to enter into
and advance funds under the Equipment Lease Agreement, dated as of August 20,
1993 (as amended from time to time, the "Lease"), with Pledgor and one or more
Schedules in connection with the Lease (the "Schedules"), and (ii) to secure
the payment of rentals and performance of all Pledgor's other obligations under
this Agreement, the Lease and all exhibits and Schedules thereto
(collectively, the "Obligations"), Pledgor shall deposit and pledge with
Pledgee, on the Delivery Date of each Schedule, a cash collateral security
deposit (the "Security Deposit") in the amount of six percent (6%) of Lessor's
Cost under such Schedule (such terms and other terms not otherwise defined
herein having the meaning therefor as set forth in the Lease or the Schedules).

         NOW THEREFORE, it is agreed:

         1.      Delivery of Deposit; Earnings.  Pledgor shall, on or before
the Delivery Date of each Schedule, deliver the Security Deposit for such
Schedule to Pledgee to secure the due and punctual payment and performance of
the Obligations.  Pledgor will receive simple interest on the Security Deposit
at a rate equal to four and one-half percent (4.5%) per annum (the "Earnings"),
such Earnings to be paid to Pledgor when and if the Security Deposit is
returned to Pledgor in accordance with the terms hereof.  The Agent may
commingle the Security Deposit and Earnings with its own funds or funds of the
Pledgee or otherwise deposit such Security Deposit in any bank selected by
Pledgee.

         2.      Grant of Security.  All funds held by the Pledgee,
representing the Security Deposit and any Earnings, shall constitute collateral
security for the performance by Pledgor of all its Obligations.  Accordingly,
Pledgor assigns, delivers, pledges and conveys to Pledgee, and grants to
Pledgee a first priority, perfected security interest in and to the Security
Deposit and all Earnings for the prompt and unconditional fulfillment of the
Obligations.



                                       1
   63
         3.      Deposit Defaults.  If any default or Event of Default under
the Lease (each being a "Deposit Default") by Pledgor shall occur and be
continuing, earnings accrued on the Security Deposit for Pledgor's benefit
shall cease on notice of such Deposit Default to Pledgor.  Pledgee may
thereupon apply the Security Deposit and any Earnings (accrued to the date of
such default notice), in such manner as Pledgee reasonably determines, towards
the satisfaction of the Obligations, including the payment of all costs and
expenses incurred by Pledgee as a result of any Deposit Default.

         4.      Enforcement.  Pledgee shall have no duty to commence an action
against or seek recourse from Pledgor in the event of a Deposit Default first
before enforcing the provisions of this Agreement.  The Obligations of Pledgor
shall be absolute and unconditional, and shall remain in force and effect
without regard to, and shall not be released or discharged or in any way
affected by:

                 (a)      any amendment or modification of or supplement to
the Lease or any exhibit or Schedule thereto, or to this Agreement;

                 (b)      any exercise or non-exercise of any right, remedy or
privilege under or in respect to this Agreement, the Lease or any exhibit or
Schedule thereto, or any other instrument provided for in any thereof, or any
waiver, consent, indulgence or actions or inaction with respect to any such
instrument;

                 (c)      any bankruptcy, insolvency, reorganization,
arrangement, readjustment, composition, liquidation or similar proceeding of or
against Pledgor; or

                 (d)      any payment received by Pledgee and subsequently
refunded or returned to Pledgor or anyone on behalf of Pledgor.

         5.      Return of Security Deposit.  So long as no Event of Default
shall have occurred and be continuing under the Lease, at the end of the Term
of each Schedule, the Security Deposit with respect to such Schedule shall be
applied first to Pledgor's end-of-Term obligations to Pledgee with respect to
such Schedule, and the balance (if any) of such Security Deposit with respect
to such Schedule and Earnings attributable thereto (less any portion thereof
applied or otherwise utilized pursuant to this Agreement) shall be delivered to
Pledgor.

         6.      Further Assurances.  Pledgor will promptly execute and deliver
to Pledgee such further reasonable documents and take such further reasonable
action as Pledgee may request in order to more effectively carry out the intent
and purpose of this Agreement or an assignment of Pledgee's interest herein.

         7.      Notices.  Notices required or permitted hereunder shall be
given in accordance with the Lease.
  



                                       2
   64
         8.      Amendments and Supplements.  No agreement shall be effective
to amend, supplement or discharge this Agreement in whole or in part unless
such agreement is in writing, signed by the parties hereto.

         9.      Assignability.  This Agreement shall be binding upon and shall
inure to the benefit of the successors and assigns of the parties hereto.
Pledgor hereby acknowledges that Lessor's rights under this Agreement may be
assigned at any time to any person having an interest in the Lease.

         10.     Governing Law.  This Agreement shall be governed by and
construed under the laws of the State of California.

         11.     Assignment.  Pledgor shall not transfer or assign, in whole or
in part, any of its rights under this Agreement.  Pledgee shall have the
absolute right to transfer or assign to any person, firm, partnership,
corporation or other entity, for security or otherwise, any or all of Pledgee's
obligations, benefits and interests under this Agreement without the consent of
or notice to Pledgor.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be executed as of the date first above written.

                 4.       Conditions.  Lessor's obligations under the Lease and
this Schedule are subject to the prior satisfaction of the following conditions

satisfactory to Lessor:

                 (i)      All acceptable waivers of landlords and/or
mortgagees, substantially in the form of Exhibit B to the Lease.

                 (ii)     To the extent Lessor deems it necessary, a release or

                 (iv)     Copies of invoices, purchase orders and cancelled
checks relating to all Units being placed under the Lease pursuant to a
sale/leaseback on the Delivery Date of this Schedule and/or a Purchase Order

                              FINANCING STATEMENT

          DEBTOR (Lessee): CALYPTE BIOMEDICAL CORPORATION
          SECURED PARTY (Lessor): MMC/GATX Partnership No. I

          ITEM 6: The items which shall constitute Lessor's equipment and other
personal property under the Master Equipment Lease Agreement, dated as of
August 20, 1993, as amended or supplemented from time to time (the "Lease"),
between MMC/GATX Partnership No. I ("MMC/GATX"), and Calypte Biomedical
Corporation ("Lessee," such term and other terms not defined herein having the
meaning referred to in the Lease) and the Schedules to the Lease, are as
follows:

          All right, title and interest of the Lessee in and to each and every
Unit of equipment, tenant improvements, fixtures, software, parts, components
or personal property covered by the Lease (including all Schedules executed in
connection therewith) and as further described below (which such equipment,
tenant improvements, fixtures, software, parts, components and personal
property shall remain subject to the lien of the Lease until specifically
released in writing) whether or not any such equipment, tenant improvements,
fixtures, software, parts, components and personal property is thereafter
purported to be sold, destroyed, released, subleased, assigned, conveyed,
transferred or otherwise disposed of; together with all accessories, equipment,
parts and appurtenances appertaining or attached to any of such equipment,
tenant improvements, fixtures, software, parts, components or personal
property, whether now owned or hereafter acquired, and all substitutions,
renewals or replacements of and additions, improvements, accessions and
accumulations to any and all of such equipment, tenant improvements, fixtures,
software, parts, components or personal property, together with all the income,
profits and avails therefrom and the proceeds thereof, including, without
limitation, insurance payments and all proceeds from sales or other
dispositions thereof.

          The Lease (including all schedules executed in connection therewith)
is intended by the parties thereto to be a true lease.  However, if
notwithstanding the intent of the parties, the Lease is held to create a
secured financing or lease for security, the Lessee shall be deemed to have
granted to MMC/GATX a security interest in the above-described equipment and
other property.

          The specific Units constituting equipment and personal property under
Schedules 1, 2 and 3 to the Lease include, without limitation, the equipment
and property set forth on the attached Annex A which is made a part hereof.

          The equipment and personal property set forth on the attached Annex A
was sold by Lessee to Lessor prior to being leased by Lessor to Lessee.

Other Security:

          That certain Security Deposit and proceeds thereof under the Security
Deposit Pledge Agreement, dated as of August 20, 1993, between MMC/GATX and
Lessee.

         DEBTOR (Lessee):                  CALYPTE BIOMEDICAL CORPORATION
         SECURED PARTY (Lessor):           MMC/GATX Partnership No. I

Item 6: The items which shall constitute Lessor's equipment and other personal
property under the Master Equipment Lease Agreement, dated as of August 20,
1993, as amended or supplemented from time to time (the "Lease"), between
MMC/GATX Partnership No. I ("MMC/GATX"), and Calypte Biomedical Corporation
("Lessee," such term and other terms not defined herein having the meaning
referred to in the Lease) and the Schedules to the Lease, are as follows:

         All right, title and interest of the Lessee in and to each and every
Unit of equipment, tenant improvements, fixtures, software, parts, components
or personal property covered by the Lease (including all Schedules executed in
connection therewith) and as further described below (which such equipment,
tenant improvements, fixtures, software, parts, components and personal
property shall remain subject to the lien of the Lease until specifically
released in writing) whether or not any such equipment, tenant improvements,
fixtures, software, parts, components and personal property is thereafter
purported to be sold, destroyed, released, subleased, assigned, conveyed,
transferred or otherwise disposed of; together with all accessories,
equipment, parts and appurtenances appertaining or attached to any of such
equipment, tenant improvements, fixtures, software, parts, components or
personal property, whether now owned or hereafter acquired, and all
substitutions, renewals or replacements of and additions, improvements,
accessions and accumulations to any and all of such equipment, tenant
improvements, fixtures, software, parts, components or personal property;
together with all the income, profits and avails therefrom and the proceeds
thereof, including, without limitation, insurance payments and all proceeds
from sales or other dispositions thereof.

         The Lease (including all schedules executed in connection therewith)
is intended by the parties thereto to be a true lease.  However, if
notwithstanding the intent of the parties, the Lease is held to create a
secured financing or lease for security, the Lessee shall be deemed to have
granted to MMC/GATX a security interest in the above-described equipment and
other property.

         The specific Units constituting equipment and personal property under
Schedule 1 include, without limitation, the equipment and property set forth on
the attached Annex A which is made a part hereof.

         The above goods are, or may become, fixtures on the real property
described in Schedule 2 to this financing statement, commonly known as 1440
Fourth Street, Berkeley, California 94710.

Section E of the Proposal Letter: "A Commitment Fee of $15,000 is required by
- -------------------------------------------------------------------------------
the Lessor to initiate its due diligence review process. This deposit is
- -------------------------------------------------------------------------------
refundable if the transaction is not approved by the Lessor, which approval is
- -------------------------------------------------------------------------------
in the sole discretion of the Lessor. Should the transaction be approved, any
- -------------------------------------------------------------------------------
portion of the fee not utilized to pay expenses, will be applied on a pro rata
- -------------------------------------------------------------------------------
basis to the first rental payable on each Schedule. If, subsequent to the
- -------------------------------------------------------------------------------
Lessor's approval and mutually acceptable lease documents, the Lessee does not
- -------------------------------------------------------------------------------
proceed with this transaction, fails to execute final documents with Lessor or
- -------------------------------------------------------------------------------
does not utilize the lease line, the fee shall be retained by the Lessor."
