assignee of Lessor, at such place as such assignee shall designate in writing,
and Lessee shall make such payments free and clear of all claims, demands or
setoffs against Lessor or such assignee. Whenever any payment (of rent or

         Lessee requests Lessor to order the Equipment described in any
Equipment Schedule executed by Lessee from the supplier named in such Equipment
Schedule, to arrange for delivery to Lessee at Lessee's expense, and to pay for

Equipment, and that Lessor will rely on specifications provided by Lessee in
ordering the Equipment; (b) Lessee shall be responsible for all costs and
expenses relating to the selection, shipment, delivery, assembly, installation,
testing, adjusting, servicing, operation and acceptance of the Equipment; (c)

supplier will occur only after Lessee has confirmed (on Lessor's Delivery and
Acceptance Certificate) satisfactory delivery, assembly, installation,
inspection and acceptance of the Equipment; (d) Lessor shall have no
responsibility for any delay, failure or refusal on the part of any supplier to

the date that Lessor orders the Equipment; (g) no supplier is Lessor's agent, or
authorized to bind Lessor or waive or alter any provision of this Master Lease
or any Equipment Schedule; and (h) if Lessee cancels this Master Lease after
execution of such but prior to the Lessee's execution of the Delivery and
Acceptance Certificate, Lessor may withhold and keep any deposits or funds paid
by Lessee to Lessor.
5.       EQUIPMENT SELECTION; DISCLAIMER OF WARRANTIES; WAIVERS.
         (a) Lessee acknowledges, represents and warrants that Lessee has made
the selection of Equipment based on Lessee's own judgment, and expressly
disclaims any reliance upon statements made by Lessor or Lessor's agents,
employees or salespersons.
         (b) LESSOR MAKES NO REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS
TO THE CAPACITY, CONDITION, DESIGN, DURABILITY, MATERIAL, MERCHANTABILITY,
PERFORMANCE, QUALITY, SUITABILITY, WORKMANSHIP OR VALUE OF THE EQUIPMENT OR ITS
FITNESS FOR ANY PARTICULAR PURPOSE OR THAT THE EQUIPMENT WILL SATISFY THE
REQUIREMENTS OF ANY LAW, RULE, REGULATION, SPECIFICATION OR CONTRACT, OR ANY
OTHER REPRESENTATION OR WARRANTY OF ANY KIND OR NATURE WHATSOEVER WITH RESPECT
TO THE EQUIPMENT OR ANY ASSOCIATED ITEM OR ANY ASPECT THEREOF. AS TO THE LESSOR,
LESSEE LEASES THE EQUIPMENT "AS IS".
         (c) Lessee acknowledge that (i) Lessor is neither the manufacturer of
the Equipment nor a manufacturer's agent, supplier or dealer, and has no
familiarity with the Equipment; and (ii) Lessor shall have no obligation to
assemble, install, test, adjust or service the Equipment.
         (d) Lessor shall not be liable, to Lessee or otherwise, to any extent
whatsoever, for the selection, quality, condition, merchantability, suitability,
fitness, operation or performance of the Equipment. Without limiting the
generality of the foregoing, Lessor shall not be liable, to Lessee or otherwise,
for any liability, claim, loss, damage or expense of any kind or nature
(including strict negligent liability in tort) caused, directly or indirectly,
by the Equipment or any inadequacy thereof for any purpose, or any deficiency or
defect therein, or the use or maintenance thereof, or any repairs, servicing or
adjustments thereto; or any delay in providing or failure to provide any part
thereof, or any interruption or loss of service thereof, or any loss of
business, or any damage whatsoever and howsoever caused.
         (e) REGARDLESS OF CAUSE, LESSEE WILL NOT ASSERT ANY CLAIM WHATSOEVER
AGAINST LESSOR FOR LOSS OF ANTICIPATORY PROFITS OR ANY OTHER INDIRECT, SPECIAL
OR CONSEQUENTIAL DAMAGES. IT IS EXPRESSLY UNDERSTOOD AND AGREED THAT EACH AND
EVERY PROVISION OF THIS

<Page>

AGREEMENT WHICH PROVIDES FOR A LIMITATION OF LIABILITY, DISCLAIMER OF
WARRANTIES OR EXCLUSION OF DAMAGES, IS INTENDED BY THE PARTIES TO BE
SEVERABLE FROM ANY OTHER PROVISION AND IS A SEPARABLE AND INDEPENDENT ELEMENT
OF RISK ALLOCATION AND IS INTENDED TO BE ENFORCED AS SUCH.
         (f) If the Equipment fails to comply with any representation or
warranty made by the supplier or manufacturer thereof, or is defective or
improperly assembled or installed or otherwise unsatisfactory for any reason,
Lessee shall make claim on account thereof against the supplier or manufacturer
thereof, and Lessee shall nevertheless pay all rent and perform all other
obligations under this Master Lease and all Equipment Schedules without
asserting any claim against Lessor. Lessor hereby assigns to Lessee, without
recourse and solely for the purpose of prosecuting such a claim, all rights that
Lessor may have against the supplier and manufacturer of Equipment for breach of
warranty or other representations with respect to the Equipment; provided,
however that this assignment shall not preclude Lessor, in its sole discretion
from asserting and prosecuting such a claim. Lessee shall indemnify and hold
Lessor harmless from and against any and all claims, costs, expenses, damages,
losses and liabilities incurred or suffered by Lessor as a result or incident to
any such action by Lessee for breach of warranty or other representations with
respect to the Equipment.
         (g) Lessor makes no representation or warranty as to the treatment of
this Master Lease or any Equipment Schedule for tax or accounting purposes or
otherwise.
         (h) Lessee hereby waives its rights and remedies under the Uniform
Commercial Code Section 2A-508 through 2A-522 with respect to Lessee's right to
cancel any Equipment Schedule, reject any of the Equipment, recover damages or
any other rights and remedies provided thereunder in connection with any default
by Lessor or any other circumstances therein provided.
6.  TITLE AND ASSIGNMENT.
         (a) Nothing contained in this Master Lease, or in any Equipment
Schedule, shall give or convey to Lessee any right, title or interest in or to
the Equipment, or any additions, upgrades, accessions, or improvements thereto,
except as a Lessee as set forth in this Master Lease and such Equipment
Schedule, and Lessee represents and agrees that Lessee shall hold the Equipment
subject and subordinate to the rights of the owner thereof. The Equipment is and
at all times shall remain the property of Lessor (or Lessor's successor in
interest), and except as expressly set forth in this Master Lease or any
Equipment Schedule, Lessee shall have no right, title, equity or interest in the
Equipment and no right or option to purchase or otherwise acquire title to or
ownership of the Equipment. Lessee shall, at Lessee's sole cost and expense: (i)
defend and protect the ownership of, title to, and interest in the Equipment of
Lessor, Lessor's successors in interest, and any assignee or secured party,
against all parties claiming against or through Lessee; (ii) keep the Equipment
free and clear from any legal process, liens, claims, demands and encumbrances
(except those incurred by Lessor); and (iii) give Lessor prompt written notice
of any legal process, liens, claims, demands and encumbrances made by any party
(except Lessor) with respect to the Equipment. Lessee shall, and Lessor may on
behalf of Lessee, at Lessee's expense, execute and file such financing
statements, applications for registration and other documentation as Lessor
shall require for the purpose of protecting or perfecting the interest of
Lessor, or any assignee, transferee or secured party, in the Equipment.
         (b) Lessee shall, at Lessee's expense, affix to the Equipment such
labels, signs or other devices as Lessor may supply to identify Lessor as the
owner and Lessor of the Equipment. Lessee authorizes Lessor to insert in any
Equipment Schedule and in any financing statement or other documents the serial
numbers and other identification data of the Equipment when determined by
Lessor. The Equipment is and at all times shall remain personal property
regardless of any attachment or affixation of the Equipment to any real property
or improvements thereon.
         (c) LESSEE SHALL NOT, WITHOUT LESSOR'S PRIOR WRITTEN CONSENT, (i)
ASSIGN THIS MASTER LEASE OR ANY EQUIPMENT SCHEDULE OR ANY INTEREST HEREIN OR
THEREIN, (ii) ENTER INTO ANY SUBLEASE, LOAN OR SIMILAR ARRANGEMENT WITH RESPECT
TO THE EQUIPMENT, OR (iii) TRANSFER, ASSIGN, CONVEY, ENCUMBER, PLEDGE OR
OTHERWISE DISPOSE OF ANY EQUIPMENT OR ANY INTEREST THEREIN; AND ANY ATTEMPT BY
LESSEE TO DO ANY OF THE FOREGOING WITHOUT LESSOR'S PRIOR WRITTEN CONSENT SHALL
BE VOID.
         (d) Lessee shall keep, maintain and use the Equipment only at the place
designated on the Equipment Schedule, and shall not move the Equipment to any
other location without the Lessor's prior written consent.
         (e) This Master Lease and any rights of Lessor hereunder and under any
Equipment Schedule shall be assignable by Lessor without notice to or the
consent of Lessee. Lessee acknowledges and understands that the terms and
conditions of each Equipment Schedule have been fixed by Lessor in anticipation
of Lessor's ability to sell and assign its interest or grant a security interest
under each Equipment Schedule and the Equipment listed therein in whole or in
part to a security assignee (the "Secured Party") for the purpose of either
assigning: (i) Lessee's obligation to pay rent pursuant to such Equipment
Schedule (Lessor having transferred the right to receive such rent to the
Secured Party), or (ii) securing a loan to Lessor. Lessor may also sell and
assign its rights as owner and lessor of the Equipment under any Equipment
Schedule to an assignee (the "Assignee") which may be represented by a bank or a
trust company acting as a trustee (the "Owner Trustee") for the Assignee. After
such assignments the term Lessor shall mean, as the case may be, such Assignee
or Owner Trustee and any Secured Party (collectively "Lessor Transferee").
Lessee acknowledges and agrees that:
   (1) Any such Lessor Transferee shall have and be entitled to exercise any and
       all discretion, rights and powers of Lessor hereunder or under any
       Equipment Schedule, but such Lessor Transferee shall not be obligated to
       perform any of Lessor's obligations hereunder or under any Equipment
       Schedule; provided, however, that such Lessor Transferee shall not
       disturb Lessee's quiet and peaceful possession of the Equipment and use
       thereof for its intended purpose during the terms hereof so long as
       Lessee is not in default of any provision hereof and such Lessor
       Transferee continues to timely receive all amounts of [illegible] payable
       under such Equipment Schedule;
   (2) Lessee will pay all rent and any and all other amounts payable by Lessee
       under any Equipment Schedule to such Lessor Transferee, notwithstanding
       and Lessee hereby waivers any defense or claim of whatever nature,
       whether by reason of breach of such Equipment Schedule or otherwise,
       which Lessee may or might now or hereafter have as against Lessor or any
       prior Lessor Transferee (Lessee reserving its right to have recourse
       directly against Lessor on account of any such defense or claim); and
   (3) Subject to and without impairment of Lessee's leasehold rights in and to
       the Equipment, Lessee holds the Equipment for such Lessor Transferee to
       the extent of such Lessor Transferee's rights therein.
7.  NET LEASE, TAXES AND FEES.
         (a) Lessor and Lessee acknowledge and agree that each Equipment
Schedule constitutes a net lease and that Lessee's obligation to pay all rent
and any and all amounts payable by Lessee under any Equipment Schedule shall be
absolute and unconditional, and shall not be subject to any abatement,
reduction, setoff, defense, counterclaim, interruption, deferment or recoupment
for any reason whatsoever; and that such payments shall be and continue to be
payable in all events.
         (b) Lessee shall, at Lessee's sole cost and expense and in addition to
the rent due under any Equipment Schedule, promptly pay all taxes, assessments,
license fees, permit fees, registration fees, fines, interest, penalties and all
other governmental charges (including without limitation income, gross receipts,
sales, use, excise, personal property, ad valorem, stamp, documentary and other
taxes), whether levied, assessed or imposed on Lessee, Lessor, the Equipment or
otherwise, relating to the Equipment or the delivery, leasing, operations,
ownership, possession, purchase, registration rental, sales or use thereof
during the term of any Equipment Schedule, or the interest of Lessee in the
Equipment or under any Equipment Schedule, or the rental or other payments
thereunder or earnings arising therefrom (excepting only taxes on Lessor's net
income). Lessee shall file all returns required in connection therewith and
shall promptly furnish copies to Lessor. Lessee shall reimburse Lessor for any
such taxes paid by Lessor within ten (10) days of receipt of Lessor's invoice
therefor. Any applicable sales tax will be paid to the manufacturer,
manufacturer's agent, supplier, dealer or appropriate taxing agency by Lessor.
Where applicable, Lessee acknowledges that such tax may have been included in
calculating lease payment.
8.       CARE, USE, MAINTENANCE AND REPAIR, AND INSPECTION BY LESSOR.
         (a) Lessee shall, at Lessee's sole expense, at all times during the
term of such Equipment Schedule and until return of the Equipment to Lessor, (i)
maintain the Equipment in good operating order, repair, condition, appearance
and protect the Equipment from deterioration, and provide all accessories,
upgrades, repairs, replacement parts and service required therefor; (ii) enter
into and maintain a maintenance contract with the manufacturer of the Equipment
or, with the prior written consent of Lessor, with such other party as shall be
acceptable to Lessor, and shall provide Lessor with a copy of such contract and
all supplements thereto; (iii) use the Equipment in a careful, proper and lawful
manner in accordance with standards, specifications or instructions issued by
the manufacturer, and provide necessary site preparation, supplies, energy and
personnel; (iv) comply with all of the laws, ordinances, rules, regulations and
other requirements relating to the installation, possession, use or maintenance
of the Equipment, including the requirements of any applicable insurance policy
or warranty; (v) obtain and comply with the requirements of all

<Page>

permits, licenses and agreements relating to the installation, possession,
use or maintenance of the Equipment; and (vi) purchase, or permit Lessor to
purchase, any and all additions, improvements, upgrades (as and when any
upgrades may become available) and maintenance contracts associated with such
upgrades, or accessions to any of the Equipment which Lessor may permit or
require Lessee to acquire or which Lessor may, at its option, elect to
acquire, with the cost of any and all such additions, improvements, upgrades,
maintenance contracts or accessions to be treated as additional original
equipment cost with respect to the applicable items of Equipment and which
additional cost shall be amortized as additional rental payments by
increasing the monthly rental amount payable under Section 3 hereof by the
amount corresponding to the amount which would be payable as monthly rent
hereunder as if such additional cost constituted a portion of the original
equipment cost of the applicable Equipment for Equipment to be leased under
the applicable Equipment Schedule for a term equal to the remaining lease
term of the applicable Equipment Schedule.
         (b) Unless Lessor otherwise consents in writing, Lessee shall not: (i)
part with possession of or control over the Equipment; (ii) permit any party
other than Lessee and Lessee's qualified employees to operate the Equipment;
(iii) permit any nonqualified party to repair or service the Equipment; (iv)
permit the Equipment to be used for personal, family, household or agricultural
purposes; or (v) make any additions, alterations or improvements to the
Equipment other than as required or permitted by the terms of this Master Lease.
All repairs, replacement parts, alterations, additions, improvements, upgrades
and accessions to any of the Equipment, whether or not any of the foregoing was
authorized, required, financed or purchased by Lessor, shall become the property
of Lessor.
         (c) Upon the request of Lessor, Lessee shall at reasonable times during
business hours make the Equipment available to Lessor for inspection at the
place where it is normally located and shall make Lessee's log and maintenance
records pertaining to the Equipment available to Lessor for inspection.
9. LESSEE'S REPRESENTATIONS AND WARRANTIES.
         Lessee hereby represents, warrants and agrees that, with respect to
this Master Lease and each Equipment Schedule:
         (a) The execution, delivery and performance thereof by Lessee have been
duly authorized by all necessary corporate or partnership action.
         (b) Each individual executing such was duly authorized to do so.
         (c) This Master Lease and each Equipment Schedule constitute legal,
valid and binding agreements of Lessee enforceable in accordance with their
terms.
         (d) The Equipment is personal property and when subjected to use by
Lessee will not become fixtures under applicable law.
         (e) During the lease term, Lessee shall deliver and shall cause all
obligators, guarantors and parties whose contracts with Lessee are used as
additional collateral under this Master Lease to deliver to Lessor audited or
reviewed financial statements for each of such party's most recent fiscal years
ended, tax returns and unaudited financial statements certified by such party
for the most recent quarter ended, consisting of at least a balance sheet,
income statements and statements of changes in financial position, and any other
information requested by Lessor from time to time, prepared in accordance with
generally accepted accounting principles.
         (f) Lessee shall provide any and all monthly operating statistics or
data and shall use its best efforts to obtain from any party benefiting from the
use of the Equipment through services provided by the Lessee any and all
operating statistics, data, or information requested by Lessor from time to
time.
         (g) The execution, delivery and performance of this Master Lease and
each Equipment Schedule will not violate any law or regulation applicable to
Lessee, or cause a default under any agreement to which Lessee is a party or is
subject.
10.  DELIVERY AND RETURN OF EQUIPMENT.
         Lessee hereby assumes the full expense of transportation and in-transit
insurance to Lessee's premises and installation thereat of the Equipment. Upon
termination (by expiration or otherwise) of each Equipment Schedule, Lessee
shall, pursuant to Lessor's instructions and at Lessee's expense (including
without limitation expenses of transportation and in-transit insurance), return
the Equipment to Lessor in the same operating order, repair, condition and
appearance as when received, less normal depreciation and wear and tear. Lessee
shall have the Equipment deinstalled and removed from its location only by the
manufacturer of the Equipment, or by such other party as shall have been
previously approved in writing by Lessor. The manufacturer or such other
preapproved party shall certify in writing to Lessor at the time of such
deinstallation that the Equipment includes all appropriate or required upgrades
and that it is in good working order. Lessee shall transport the Equipment by
means and return the Equipment to Lessor at such address all as shall be
directed by Lessor. Lessee shall bear all costs of deinstallation, removal and
return of the Equipment, including all costs as may be incurred by Lessee or
Lessor to acquire the upgrades required under the terms of this Master Lease, to
service and repair the Equipment and to otherwise put the Equipment in the
condition required under this Section 10.
11.  INSURANCE.
         During the term hereof and until return of the Equipment to Lessor,
Lessee shall, at Lessee's expense: (i) maintain insurance covering damage,
destruction, loss or theft of the Equipment from any cause whatsoever for not
less than an amount equal to the greater of the replacement value or the amount
calculated pursuant to clause (vi) of Section 15(b) hereof; (ii) maintain public
liability (including liability with respect to the use of the Equipment),
professional liability insurance (covering Lessee and its employees and any and
all other parties as may have possession of or as may operate any of the
Equipment), and property damage insurance in an amount satisfactory to Lessor;
(iii) maintain, if applicable as determined in the sole discretion of Lessor,
business interruption and automobile insurance (where the Equipment constitutes
mobile magnetic resonance imaging equipment or other mobile equipment); and (iv)
promptly notify Lessor of any actual or alleged damage, destruction, liability,
loss or theft relating to the Equipment or the use or operation thereof. All
insurance shall be in form, substance and amount satisfactory to Lessor and/or
Lessor's Transferee, shall contain a lender's form endorsement with waiver of
breach of warranty clause (form 438-BFU or its equivalent), and shall be issued
by insurers acceptable to Lessor, and shall name Lessor or any Lessor Transferee
as loss payee with respect to all policies of property insurance and as an
additional insured with respect to all other policies of insurance. Lessee shall
obtain endorsements to all such policies of insurance which shall provide that
any amendment or cancellation of any such policy shall not be effective unless
Lessor shall have been given thirty (30) days' prior written notice of any such
intended amendment or cancellation. Self-insurance is unacceptable unless Lessor
shall so provide upon its prior written consent. Lessee shall deliver to Lessor
originals or certified copies of such policies, certificates of coverage
thereunder and loss payee, additional insured, [illegible] notice of amendment
or cancellation endorsements. In addition, as collateral security for Lessee's
obligations hereunder, and under the Equipment Schedules, Lessee hereby assigns,
transfers and conveys to Lessor all of Lessee's right, title and interest in and
to all of the foregoing policies of insurance and the insurance coverage
provided thereunder and Lessee shall deliver and cause each insurer under each
of such policies of insurance to deliver to Lessor assignments of such policies
and coverage with assignments shall be in form and substance satisfactory to
Lessor.
12.  RISK OF LOSS.
         During the term of each Equipment Schedule, and until return of the
Equipment to Lessor, Lessee shall bear all risk of damage, destruction, loss or
theft of the Equipment from any cause whatsoever. No damage, destruction, loss
or theft of the Equipment or delay in payment or deficiency or absence of
insurance proceeds, and no unavailability or delay in obtaining supplies, parts
or service for the Equipment or failure of the Equipment to function for any
cause whatsoever, and no change in laws or regulations governing or restricting
the use of the Equipment (including the future enactment of any laws or
regulations prohibiting the use of the Equipment), shall release Lessee of the
obligation to pay rent or any other obligation hereunder. Upon the occurrence of
any reparable damage, Lessee shall promptly make such repairs and restore the
Equipment to good repair, condition and working order. Upon the occurrence of
any irreparable damage, destruction for loss of the Equipment, Lessee shall, at
Lessor's option: (i) replace the Equipment with like equipment in good repair,
condition and working order with documentation creating clear title thereto in
Lessor; or (ii) pay Lessor the amounts required under Section 15 of this Master
Lease to the same extent as though a default had occurred hereunder. Subject to
such conditions as Lessor may require, any insurance proceeds paid to Lessor as
a result of any damage, destruction, loss or theft of the Equipment shall be
applied to Lessee's obligations hereunder, provided that if the Equipment is not
repaired or replaced as provided above, such insurance proceeds shall be applied
first to Lessor's expected residual interest in the Equipment. Lessor shall have
no obligation to collect or pursue any claim arising from any damage,
destruction, loss or theft of the Equipment, including any claim under any
applicable insurance policy.
13.   INDEMNITY.
         Lessee shall, at Lessee's sole cost and expense, indemnify, hold
harmless and defend Lessor and its agents, employees, officers and directors,
and its successors in interest from and against any and all claims, actions,
suits, proceedings, costs, expenses, damages and liabilities, including
attorney's fees, arising out of, connected with, resulting from or relating to
the Equipment or the condition, delivery, leasing, location, maintenance,
manufacture, operation, ownership, possession, purchase, repair, repossession,
return, sale, selection, service or use thereof, including without limitation:
(i) claims involving latent or other defects (whether or not discoverable by
Lessee or Lessor), (ii) claims for trademark, patent or copyright infringement,
and (iii) claims for injury or death to persons or damage to property or loss of
business or anticipatory profits, whether resulting from acts or omissions of
Lessee or Lessor or otherwise.

<Page>

Lessee shall give Lessor prompt written notice of any claim or liability
covered by this section. The indemnities under this section shall survive the
satisfaction of all other obligations of Lessee herein and the termination of
this Master Lease or any Equipment Schedule.
14.  SECURITY DEPOSIT.
         For the purpose of securing all of Lessee's obligations under this
Master Lease and each Equipment Schedule, Lessee grants Lessor a security
interest in any security deposit described in any Equipment Schedule. Any such
security deposit may be commingled with other funds and shall be held without
interest to Lessee. Upon default under this Master Lease or any Equipment
Schedule, Lessor may, but shall not be obligated to, apply any such security
deposit to any obligation of Lessee under this Master Lease or any Equipment
Schedule, in which event Lessee shall promptly restore the amount thereof on
demand. Upon compliance by Lessee with all terms of this Master Lease and each
Equipment Schedule Lessor shall, at the end of the term of each Equipment
Schedule and the return of the Equipment to Lessor as provided herein, refund to
Lessee the balance of any security deposit pertaining to such Equipment
Schedule.
15.  DEFAULT AND REMEDIES.
         (a) The occurrences of any one or more of the following events ("Events
of Default") shall constitute a default under this Master Lease and any
Equipment Schedule: (i) Lessee's failure to pay rent or any other amount
required under an Equipment Schedule when due; (ii) Lessee's failure to perform
any other obligation or observe any other term of this Master Lease or any
Equipment Schedule; (iii) any representation or warranty made to Lessor by
Lessee or by any guarantor proves to have been false in any material respect
when made; (iv) Lessee or any guarantor suffers a material adverse change in its
financial condition; (v) an event of default shall have occurred under and be
continuing under any other agreement involving the borrowing of money by Lessee
or any guarantor; (vi) levy, seizure or attachment of any Equipment; (vii)
commencement of proceedings under any bankruptcy, arrangement, reorganization or
insolvency law by or against, or appointment of a receiver or liquidator for any

         (b) Upon the occurrence of any one or more Events of Default, Lessor
may exercise any one or more of the following remedies without demand or notice
to Lessee and without terminating or otherwise affecting Lessee's obligations

amount equal to Lessor's Return for such Equipment ("Lessor's Return" shall mean

at five percent (5%), of all unpaid rent payments to become due during the
remaining lease term; (B) all late charges provided in this Master Lease or any
Equipment Schedule; (C) all expenses, including attorney's fees, of Lessor or

Lessee shall deliver and provide such deposit; (E) any actual or anticipated
loss in tax benefits to Lessor (as determined by Lessor) resulting from the

other amounts payable by Lessee to Lessor under this Master Lease or any
Equipment Schedule or damages suffered by Lessor not otherwise compensated
herein including, without limitation, damages arising from Lessee's failure to
maintain the Equipment as provided herein. Any sale or lease of the Equipment by
Lessor after default shall be free and clear of any interest of Lessee.
         (c) The rights and remedies of Lessor hereunder are in addition to all
other rights and remedies provided by law. All of Lessor's rights and remedies
are cumulative and not exclusive, and may be exercised separately or
concurrently and in such order and manner as Lessor may determine. The exercise
of any one remedy shall not be deemed to be an election of such remedy or to
preclude the exercise of any other remedy. No default by Lessee or action by
Lessor shall result in a termination of this Master Lease or any Equipment
Schedule unless Lessor so notifies Lessee in writing, and no termination of this
Master Lease or any Equipment Schedule shall release or impair any of Lessee's
obligations hereunder or thereunder.
16.   PURCHASE OPTION
         Notwithstanding anything to the contrary in the Master Lease and
Equipment Schedule, Lessor and Lessee hereby agree, provided no default has
occurred and is continuing under the Master Lease, at the end of the Equipment
Schedule term, Lessor will sell all, but not part of, the Equipment listed on
the Equipment Schedule AS IS WHERE IS and transfer title to Lessee for the
consideration of One Hundred and One Dollar (101.00) and will execute such
documentation as necessary to effect such transfer of title to the extent title
was conveyed to Lessor. Any instrument of transfer shall contain the following:

WHATSOEVER IN REGARD TO SUCH EQUIPMENT. THE SELLER HEREBY DISCLAIMS ANY AND ALL

LIMITATION, THOSE OF MERCHANTABILITY OR FITNESS FOR USE OR FITNESS FOR ANY
PARTICULAR USE, OR OF QUALIFY, DESIGN, CONDITION, CAPACITY, SUITABILITY OR

by Lessor in connection with the execution, delivery, administration and
enforcement of this Master Lease, any Equipment Schedule, the transactions
contemplated hereby and thereby, and any costs and expenses related hereto or
thereto, including without limitation filing fees, registration fees, attorney's
fees and other out-of-pocket expenses.
18.   PERFORMANCE BY LESSOR
         If Lessee shall fail to perform any obligations under this Master Lease
or any Equipment Schedule, Lessor shall have the right, but shall not be
obligated, with or without prior notice to Lessee, to perform the same (or, in
the case of Lessee's failure to maintain insurance, Lessor may obtain insurance
protecting the interest of Lessor only), and the costs thereof, together with
interest at the lesser of eighteen percent (18%) per year or the highest lawful
rate, shall be immediately payable by Lessee as additional rent for the
Equipment.
19.   FURTHER ASSURANCES

the purpose of continuing and assuring the rights intended to be created by this

redocumentation of errors and omissions of this Master Lease and any Equipment
Schedule required by any Lessor Transferee or other successor to any interest of

or any provision hereof or thereof, shall be effective unless in writing signed
by Lessor. No delay or failure to exercise any right, power or remedy accruing
to Lessor upon any default of Lessee shall impair any such right, power and
remedy, nor shall it be construed as a waiver of any such default, or an
acquiescence therein, or in any similar default thereafter occurring, nor shall
any waiver of any single default be deemed a waiver of any other default
theretofore or thereafter occurring. Any waiver, permit, consent or approval of

                              SAN DIEGO, CALIFORNIA

PREAMBLE: This Note is a consolidation of all amounts loaned by GERALD G. LOEHR
TRUST ("Holder") to Aurora Technologies Corporation ("Aurora"), a California
Corporation. This Note cancels all loans made by GERALD G. LOEHR TRUST prior to
this date and all loan guarantees prior to this date by any and all Aurora

Aurora promises to pay to the GERALD G. LOEHR TRUST a resident of RANCHO SANTA

Thereafter principal and interest at the rate of 1.5% above the interest rate
of a thirty-year U.S. treasury note maturing February 1, 2026, shall be paid
in such equal monthly payments that the entire indebtedness shall be paid off
on February 1, 2001.

             Any or all of this Note may be prepaid without penalty. Any
prepayments shall first be applied to unpaid interest and then to principal.
Aurora agrees not to prepay any amount on this Note unless equal amounts are
paid on the other two similar loan agreements of this same date between Aurora
and JACK F. BUTLER and CLINTON L. LINGREN.

         2.  MANNER OF PAYMENTS.  All payments by Aurora under this Note shall

deduction or counterclaim of any kind whatsoever.

by this Note is obtained for business or commercial purposes and that the
proceeds of such loan will not be used primarily for personal, family, household

of demand and dishonor.

arising from, this Note.

         9.  MODIFICATION.  This Note may be modified only by a contract in
writing executed by the party to this Note against whom enforcement of such
modification is sought.

         10. HEADINGS.  The headings of the Paragraphs of this Note have been

                           AMENDMENT TO LOAN AGREEMENT

         THIS AMENDMENT TO LOAN AGREEMENT (the "Amendment") dated as of May 13,
1994 amends the Loan Agreement dated as of September 1, 1993 by and between
AURORA TECHNOLOGIES CORPORATION, a California corporation, with principal
offices at 7408 Trade Street, San Diego, California 92121-2410 (the "Company"),
and GERALD G. LOEHR, ("Lender"), as amended by the Addendum to Loan Agreement
dated as of January 1, 1994, February 17, 1994 and April 14, 1994 (collectively,
the "Original Agreement").

         WHEREAS, Lender together with JACK F. BUTLER, and CLINTON L. LINGREN,
collectively (the "Founders"), have individually entered into loan agreements
with the Company which provide for the Company to repay to the Founders
principal totaling $735,000 and interest thereon;

         WHEREAS, the Company and Kingsbury Capital Partners, L.P. ("Kingsbury")
have entered into a Stock Purchase Agreement dated as of May 13, 1994, whereby
Kingsbury will provide additional financing to the Company in exchange for
Series A Preferred Stock of the Company, pursuant to which the Company has
agreed to enter into this Amendment with Lender to amend the terms of the
Original Agreement by the terms set forth below;

         NOW, THEREFORE, in consideration of the promises and of the mutual
provisions and obligations hereinafter set forth, the parties hereto agree as
follows:

         1.  PAYMENTS.  Principal and interest under this Amendment shall be
paid as follows.

                  1.1  Interest shall be paid quarterly. The simple rate of
interest shall be six and thirty-five hundredths percent (6.35%) per annum.
Notwithstanding any provision of this Amendment, it is the intent and agreement
of the parties that in the event any interest specified herein is found to
violate any applicable law or regulation, this Amendment shall be construed or
deemed amended so that the interest is adjusted to the extent necessary to
comply with such applicable law or regulation.

                  1.2  Payment of principal shall not become due until the later
of (i) March 31, 1999 or (ii) March 31 of the year immediately following the
first year in which the Company's cash provided by operations is greater than
zero as shown on the Company's audited statement of cash flows for such year.
Subject to certain exceptions to payment provided herein, the principal shall be
paid to Lender in twelve (12) equal quarterly installments, the first such
payment to be made within forty-five (45) days of the initial due date and
subsequent quarterly installments to be paid within forty-five (45) days of the
end of each subsequent quarter. The Company shall make payment of quarterly
installments to Lender in equal proportion to the amounts paid to the other
Founders, and shall not make payment of any portion of Lender's principal before
similar payment to other Founders. Notwithstanding anything to the contrary
herein, the aggregate amount of the quarterly installments to principal paid to
Lender and the other Founders shall not exceed fifty percent (50%) of the
Company's cash provided by operations as shown on the Company's unaudited
statement of cash flows for the prior quarter, in

<Page>

which event, any unpaid amounts of principal shall be carried forward and
subsequent quarterly installments shall be adjusted accordingly to account for
the principal carried forward.

         2.  Except as set forth herein, there have been no other amendments to
the Original Agreement and all terms and conditions thereof shall remain in full
force and effect.

         3.  This Amendment may be executed in two or more counterparts, each
of which shall be deemed an original, but all of which together shall
constitute one and the same instrument.

         4.  No waiver or modification of the terms of this Amendment shall be
valid unless in writing, signed by both parties to this Amendment.

         5.  This Amendment shall be governed by and construed in accordance
with the laws of the State of California, irrespective of its choice of law
provisions.

         IN WITNESS WHEREOF, the parties have caused this Amendment to be
signed in duplicate by their duly authorized representatives. Entered into as
of the day and year first above written.
