Bank's discretion such Advances are necessary to meet Obligations which have
become due and remain unpaid. Bank shall be entitled to rely on any telephonic
notice given by a person who Bank reasonably believes to be a Responsible
Officer or a designee thereof, and Borrower shall indemnify and hold Bank
harmless for any damages or loss suffered by Bank as a result of such reliance.
Bank will credit the amount of Advances made under this Section 2.1 to
Borrower's deposit account.

                  (c)      The Committed Revolving Line shall terminate on the
Revolving Maturity Date, at which time all Advances under this Section 2. 1.1
and other amounts due under this Agreement (except as otherwise expressly
specified herein) shall be immediately due and payable.

         2.2      OVERADVANCES. If, at any time or for any reason, the amount of
Obligations owed by Borrower to Bank pursuant to Section 2. 1.1 of this
Agreement is greater than the lesser of (i) the Committed Revolving Line or (ii)
the Borrowing Base, Borrower shall immediately pay to Bank, in cash, the amount
of such excess.

         2.3      INTEREST RATES, PAYMENTS, AND CALCULATIONS.

                  (a)      INTEREST RATE. Except as set forth in Section 2.3(b),
any Advances shall bear interest, on the average daily balance thereof, at a per
annum rate equal to the Prime Rate plus 1.00%, PROVIDED, HOWEVER, if the
Borrower satisfies the Rate Reduction Conditions (as defined below), then the
Advances shall bear interest, on the average daily balance thereof, at a per
annum rate equal to the Prime Rate plus 0.25%, PROVIDED, FURTHER, the foregoing
rate reduction is to be considered effective on and after the date that Bank has
received and reviewed

                                      -9-
<Page>

Borrower's financial statements evidencing compliance with such Rate Reduction
Conditions and Bank determines that such financial statements are acceptable to
the Bank. Regardless of the foregoing, under no circumstance shall the foregoing
rate reduction become effective at any time that an Event of Default has
occurred and is continuing.

                  As used herein the term "RATE REDUCTION CONDITIONS" shall mean
the Borrower's compliance with both the following: (1) Borrower has attained,
and maintains, a Tangible Net Worth of at least $4,500,000 and (2) Borrower has
attained, and maintains, a ratio of Quick Assets to Current Liabilities of at
least 1.00 to 1.

                  (b)      DEFAULT RATE. All Obligations consisting of principal
indebtedness shall bear interest, from and after the occurrence of an Event of
Default, at a rate equal to five (5) percentage points above the interest rate
applicable immediately prior to the occurrence of the Event of Default.

                  (c)      PAYMENTS. Interest hereunder shall be due and payable
on each Payment Date. Borrower hereby authorizes Bank to debit any accounts with
Bank, including, without limitation, Account Number 3300119295 for payments of
principal and interest due on the Obligations and any other amounts owing by
Borrower to Bank. Bank will notify Borrower of all debits which Bank has made
against Borrower's accounts. Any such debits against Borrower's accounts in no
way shall be deemed a set-off. Any interest not paid when due shall be
compounded by becoming a part of the Obligations, and such interest shall
thereafter accrue interest at the rate then applicable hereunder.

                  (d)      COMPUTATION. In the event the Prime Rate is changed
from time to time hereafter, the applicable rate of interest hereunder shall be
increased or decreased effective as of 12:01 a.m. on the day the Prime Rate is
changed, by an amount equal to such change in the Prime Rate. All interest
chargeable under the Loan Documents shall be computed on the basis of a three
hundred sixty (360) day year for the actual number of days elapsed.

         2.4      CREDITING PAYMENTS. Prior to the occurrence of an Event of
Default, Bank shall credit a wire transfer of funds, check or other item of
payment to such deposit account or Obligation as Borrower specifies. After the
occurrence of an Event of Default, the receipt by Bank of any wire transfer of
funds, check, or other item of payment, whether directed to Borrower's deposit
account with Bank or to the Obligations or otherwise, shall be immediately
applied to conditionally reduce Obligations, but shall not be considered a
payment in respect of the Obligations unless such payment is of immediately
available federal funds or unless and until such check or other item of payment
is honored when presented for payment. Notwithstanding anything to the contrary
contained herein, any wire transfer or payment received by Bank after 12:00 noon
Pacific time shall be deemed to have been received by Bank as of the opening of
business on the immediately following Business Day. Whenever any payment to Bank
under the Loan Documents would otherwise be due (except by reason of
acceleration) on a date that is not a Business Day, such payment shall instead
be due on the next Business Day, and additional fees or interest, as the case
may be, shall accrue and be payable for the period of such extension.

                                      -10-

         2.5      FEES. Borrower shall pay to Bank the following:

                  (a)      FACILITY FEE: UNUSED LINE FEE. A Facility Fee equal
to $3,750 plus a variance fee of $1,000 shall be due on the Closing Date; an
additional fee shall be due and payable at such time that the amount of the
Committed Revolving Line is increased to an amount in excess of $1,500,000 and
the amount of such additional fee shall be equal to .25% of the amount of the
increase over $1,500,000. Such fees shall be deemed fully earned and
nonrefundable as of the Closing Date. Further, and in addition to the foregoing,
Borrower shall pay Bank an unused line fee, in addition to all interest and
other fees payable hereunder. The amount of such unused line fee shall be 0.375%
per annum multiplied by an amount equal to amount of applicable Committed
Revolving Line in effect from time to time MINUS the average daily balance of
the outstanding Loans. Such unused line fee shall be computed and paid
quarterly, in arrears, on the last day of January, April, July and October of
each year, commencing on April 30, 2000.

                  (b)      FINANCIAL EXAMINATION AND APPRAISAL FEES. Bank's
customary fees and out-of-pocket expenses for Bank's audits of Borrower's
Accounts, subject to the limitations applicable thereto set forth in Section 6.3

                  (c)      BANK EXPENSES. Upon demand from Bank, including,
without limitation, upon the date hereof, all Bank Expenses incurred through the
date hereof, including reasonable attorneys' fees and expenses, and, after the
date hereof, all Bank Expenses, including reasonable attorneys' fees and
expenses, as and when they become due.

         2.6      ADDITIONAL COSTS. In case any law, regulation, treaty or
official directive or the interpretation or application thereof by any court or
any governmental authority charged with the administration thereof or the
compliance with any guideline or request of any central bank or other
governmental authority (whether or not having the force of law):

                  (a)      subjects Bank to any tax with respect to payments of
principal or interest or any other amounts payable hereunder by Borrower or

on the overall net income of Bank imposed by the United States of America or any
political subdivision thereof);

                  (b)      imposes, modifies or deems applicable any deposit
insurance, reserve, special deposit or similar requirement against assets held
by, or deposits in or for the account of, or loans by, Bank; or

                  (c)      imposes upon Bank any other condition with respect to
its performance under this Agreement,

and the result of any of the foregoing is to increase the cost to Bank, reduce
the income receivable by Bank or impose any expense upon Bank with respect to
any loans, Bank shall notify Borrower thereof. Borrower agrees to pay to Bank
the amount of such increase in cost, reduction in income or additional expense
as and when such cost, reduction or expense is incurred or determined, upon
presentation by Bank of a statement of the amount and setting forth

continue in full force and effect for a term ending on the Maturity Date.
Notwithstanding the foregoing, Bank shall have the right to terminate its
obligation to make Credit Extensions under this Agreement immediately and
without notice upon the occurrence and during the continuance of an Event of
Default. Notwithstanding termination of this Agreement, Bank's lien on the
Collateral shall remain in effect for so long as any Obligations are
outstanding.

4.       CREATION OF SECURITY INTEREST

         4.1      GRANT OF SECURITY INTERESTS. Borrower grants and pledges to
Bank a continuing security interest in all presently existing and hereafter
acquired or arising Collateral in order to secure prompt payment of any and all
Obligations and in order to secure prompt performance by Borrower of each of its
covenants and duties under the Loan Documents. Except as set forth in the
Schedule, such security interest constitutes a valid, first priority security
interest in the presently existing Collateral, and will constitute a valid,
first priority security interest in Collateral acquired after the date hereof.
Borrower acknowledges that Bank may place a "hold" on any Deposit Account
pledged as Collateral to secure the Obligations. Notwithstanding termination of
this Agreement, Bank's Lien on the Collateral shall remain in effect for so long

         5.2      DUE AUTHORIZATION; NO CONFLICT. The execution, delivery, and
performance of the Loan Documents are within Borrower's powers, have been duly
authorized, and are not in conflict with nor constitute a breach of any

Bylaws, nor will they constitute an event of default under any material
agreement to which Borrower is a party or by which Borrower is bound. Borrower
is not in default under any agreement to which it is a party or by which it is
bound, which default could have a Material Adverse Effect.

                                      -13-

Insolvency Proceeding of any account debtor whose accounts are included in any
Borrowing Base Certificate as an Eligible Account.

8.       EVENTS OF DEFAULT

         Any one or more of the following events shall constitute an Event of
Default by Borrower under this Agreement:

         8.1      PAYMENT DEFAULT. If Borrower fails to pay, when due, any of
                  the Obligations.

         8.2      COVENANT DEFAULT.

                  (a)      If Borrower fails to perform any obligation under
Sections 6.3, 6.6, 6.7, 6.8, 6.9, 6.10, or 6.11 or violates any of the covenants
contained in Article 7 of this Agreement, or

                  (b)      If Borrower fails or neglects to perform, keep, or
observe any other material term, provision, condition, covenant, or agreement
contained in this Agreement, in any of the Loan Documents, or in any other
present or future agreement between Borrower and Bank and as to any default
under such other term, provision, condition, covenant or agreement that can be
cured, has failed to cure such default within 20 days after the occurrence
thereof; provided, however, that if the default cannot by its nature be cured
within the 20 day period or cannot after diligent attempts by Borrower be cured
within such 20 day period, and such default is likely to be cured within a
reasonable time, then Borrower shall have an additional reasonable period (which
shall not in any case exceed thirty (30) days) to attempt to cure such default,
and within such reasonable time period the failure to have cured such default
shall not be deemed an Event of Default (provided that no Advances will be
required to be made during such cure period);

         8.3      MATERIAL ADVERSE CHANGE. If there (i) occurs a material
adverse change in the business, operations, or condition (financial or
otherwise) of the Borrower, or (ii) is a material impairment of the prospect of
repayment of any portion of the Obligations or (iii) is a material impairment of
the value or priority of Bank's security interests in the Collateral;

         8.4      ATTACHMENT. If any material portion of Borrower's assets is
attached, seized, subjected to a writ or distress warrant, or is levied upon, or
comes into the possession of any trustee, receiver or person acting in a similar
capacity and such attachment, seizure, writ or distress warrant or levy has not
been removed, discharged or rescinded within ten (10) days, or if Borrower is
enjoined, restrained, or in any way prevented by court order from continuing to
conduct all or any material part of its business affairs, or if a judgment or
other claim becomes a lien or encumbrance upon any material portion of
Borrower's assets, or if a notice of lien, levy, or assessment is filed of
record with respect to any of Borrower's assets by the United States Government,
or any department, agency, or instrumentality thereof, or by any state, county,
municipal, or governmental agency, and the same is not paid within ten (10) days
after Borrower receives notice thereof, provided that none of the foregoing
shall constitute an Event of Default where such action or event is stayed or an
adequate bond has been posted pending a good faith contest by Borrower (provided
that no Credit Extensions will be required to be made during such cure period);

         8.5      INSOLVENCY. If Borrower becomes insolvent, or if an Insolvency
Proceeding is commenced by Borrower, or if an Insolvency Proceeding is commenced
against Borrower and is

                                      -20-
<Page>

not dismissed or stayed within 30 days (provided that no Advances will be made
prior to the dismissal of such Insolvency Proceeding);

         8.6      OTHER AGREEMENTS. If there is a default in any agreement to
which Borrower is a party with a third party or parties resulting in a right by
such third party or parties, whether or not exercised, to accelerate the
maturity of any Indebtedness in an amount in excess of One Hundred Thousand
Dollars ($100,000) or that could have a Material Adverse Effect; or any guaranty
of the Obligations ceases for any reason to be in full force and effect, or any
Guarantor fails to perform any obligation under any such guaranty, or any
material misrepresentation or material misstatement exists now or hereafter in
any warranty or representation set forth in any such guaranty, or any of the
circumstances described in Sections 8.4, 8.5 or 8.8 occur with respect to any
Guarantor;

         8.7      SUBORDINATED DEBT. If Borrower makes any payment on account of
Subordinated Debt, except to the extent such payment is allowed under any
subordination agreement entered into with Bank;

         8.8      JUDGMENTS. If a judgment or judgments for the payment of money
in an amount, individually or in the aggregate, of at least Fifty Thousand
Dollars ($50,000) shall be rendered against Borrower and shall remain
unsatisfied and unstayed for a period of ten (10) days (provided that no Credit
Extensions will be made prior to the satisfaction or stay of such judgment);

         8.9      MISREPRESENTATIONS. If any material misrepresentation or
material misstatement exists now or hereafter in any warranty or representation
set forth herein or in any certificate or writing delivered to Bank by Borrower
or any Person acting on Borrower's behalf pursuant to this Agreement or to
induce Bank to enter into this Agreement or any other Loan Document; or

         8.10     FAILURE TO OBTAIN GOVERNMENTAL APPROVAL. If: (A)(i) a product
of the Borrower (including, without limitation, the gamma ray camera product)
accounts for a material portion of the Borrower's revenues or its projected
revenues, and (ii) governmental approvals are required for the sale of such
product in a specific market or are required for the use of such product in a
particular manner and the sales of such product with respect to such specific
market or such use produce a material portion of the revenues arising from such
product and (iii) such product fails to obtain approval by all of the
appropriate United States governmental authorities or any such approval, once
obtained, is thereafter cancelled or otherwise rescinded; PROVIDED that the
status of such lack of approval for such product or the status of the
cancellation or rescission thereof (any such lack of approval, cancellation or
rescission being referred to herein as a "Non-Approval Event") continues for at
least a period of 30 days after the initial occurrence of the Non-Approval
Event, within which period Borrower seeks to use its best efforts to reverse
such Non-Approval Event.

9.       BANK'S RIGHTS AND REMEDIES

         9.1      RIGHTS AND REMEDIES. Upon the occurrence and during the
continuance of an Event of Default, Bank may, at its election, without notice of
its election and without demand, do any one or more of the following, all of
which are authorized by Borrower:

                                      -21-
<Page>

                  (a)      Declare all Obligations, whether evidenced by this
Agreement, by any of the other Loan Documents, or otherwise, immediately due and
payable (provided that upon the occurrence of an Event of Default described in
Section 8.5 all Obligations shall become immediately due and payable without any
action by Bank);

                  (b)      Cease advancing money or extending credit to or for
the benefit of Borrower under this Agreement or under any other agreement
between Borrower and Bank;

                  (c)      Settle or adjust disputes and claims directly with
account debtors for amounts, upon terms and in whatever order that Bank
reasonably considers advisable;

                  (d)      Without notice to or demand upon Borrower, make such
payments and do such acts as Bank considers necessary or reasonable to protect
its security interest in the Collateral. Borrower agrees to assemble the
Collateral if Bank so requires, and to make the Collateral available to Bank as
Bank may designate. Borrower authorizes Bank to enter the premises where the
Collateral is located, to take and maintain possession of the Collateral, or any
part of it, and to pay, purchase, contest, or compromise any encumbrance,
charge, or lien which in Bank's determination appears to be prior or superior to
its security interest and to pay all expenses incurred in connection therewith.
With respect to any of Borrower's premises, Borrower hereby grants Bank a
license to enter such premises and to occupy the same, without charge in order
to exercise any of Bank's rights or remedies provided herein, at law, in equity,
or otherwise;

                  (e)      Without notice to Borrower set off and apply to the
Obligations any and all (i) balances and deposits of Borrower held by Bank, or
(ii) indebtedness at any time owing to or for the credit or the account of
Borrower held by Bank;

                  (f)      Ship, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner provided
for herein) the Collateral. Bank is hereby granted a non-exclusive, royalty-free
license or other right, solely pursuant to the provisions of this Section 9. 1,
to use, without charge, Borrower's labels, patents, copyrights, mask works,
rights of use of any name, trade secrets, trade names, trademarks, service
marks, and advertising matter, or any property of a similar nature, as it
pertains to the Collateral, in completing production of, advertising for sale',
and selling any Collateral and, in connection with Bank's exercise of its rights
under this Section 9.1, Borrower's rights under all licenses and all franchise
agreements shall inure to Bank's benefit, subject to the provisions of the
Supply and Development Agreement dated as of June 23, 1998 between Ethicon
Endo-Surgery, Inc. and Borrower;

                  (g)      Sell the Collateral at either a public or private
sale, or both, by way of one or more contracts or transactions, for cash or on
terms, in such manner and at such places (including Borrower's premises) as Bank
determines is commercially reasonable, and apply the proceeds thereof to the
Obligations in whatever manner or order it deems appropriate;

                  (h)      Bank may credit bid and purchase at any public sale,
or at any private sale as permitted by law; and

                                      -22-
<Page>

                  (i)      Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.

         9.2      POWER OF ATTORNEY. Effective only upon the occurrence and
during the continuance of an Event of Default, Borrower hereby irrevocably
appoints Bank (and any of Bank's designated officers, or employees) as
Borrower's true and lawful attorney to: (a) send requests for verification of
Accounts or notify account debtors of Bank's security interest in the Accounts;
(b) endorse Borrower's name on any checks or other forms of payment or security
that may come into Bank's possession; (c) sign Borrower's name on any invoice or
bill of lading relating to any Account, drafts against account debtors,
schedules and assignments of Accounts, verifications of Accounts, and notices to
account debtors; (d) make, settle, and adjust all claims under and decisions
with respect to Borrower's policies of insurance; and (e) settle and adjust
disputes and claims respecting the accounts directly with account debtors, for
amounts and upon terms which Bank determines to be reasonable; provided Bank may
exercise such power of attorney to sign the name of Borrower on any of the
documents described in Section 4.2 regardless of whether an Event of Default has
occurred. The appointment of Bank as Borrower's attorney in fact, and each and
every one of Bank's rights and powers, being coupled with an interest, is
irrevocable until all of the Obligations have been fully repaid and performed
and Bank's obligation to provide advances hereunder is terminated.

         9.3      ACCOUNTS COLLECTION. Upon the occurrence and during the
continuance of an Event of Default, Bank may notify any Person owing funds to
Borrower of Bank's security interest in such funds and verify the amount of such
Account. Borrower shall collect all amounts owing to Borrower for Bank, receive
in trust all payments as Bank's trustee, and if requested or required by Bank,
immediately deliver such payments to Bank in their original form as received
from the account debtor, with proper endorsements for deposit.

         9.4      BANK EXPENSES. If Borrower fails to pay any amounts or furnish
any required proof of payment due to third persons or entities, as required
under the terms of this Agreement, then Bank may do any or all of the following:
(a) make payment of the same or any part thereof-, (b) set up such reserves
under the Committed Revolving Line as Bank deems necessary to protect Bank from
the exposure created by such failure; or (c) obtain and maintain insurance
policies of the type discussed in Section 6.6 of this Agreement, and take any
action with respect to such policies as Bank deems prudent. Any amounts so paid
or deposited by Bank shall constitute Bank Expenses, shall be immediately due
and payable, and shall bear interest at the then applicable rate hereinabove
provided, and shall be secured by the Collateral. Any payments made by Bank
shall not constitute an agreement by Bank to make similar payments in the future
or a waiver by Bank of any Event of Default under this Agreement.

         9.5      BANK'S LIABILITY FOR COLLATERAL. So long as Bank complies with
reasonable banking practices, Bank shall not in any way or manner be liable or
responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage
thereto occurring or arising in any manner or fashion from any cause; (c) any
diminution in the value thereof; or (d) any act or default of any carrier,
warehouseman, bailee, forwarding agency, or other person whomsoever. All risk of
loss, damage or destruction of the Collateral shall be borne by Borrower.

                                      -23-
<Page>

         9.6      REMEDIES CUMULATIVE. Bank's rights and remedies under this
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies not expressly set forth herein as
provided under the Code, by law, or in equity. No exercise by Bank of one right
or remedy shall be deemed an election, and no waiver by Bank of any Event of
Default on Borrower's part shall be deemed a continuing waiver. No delay by Bank
shall constitute a waiver, election, or acquiescence by it. No waiver by Bank
shall be effective unless made in a written document signed on behalf of Bank
and then shall be effective only in the specific instance and for the specific
purpose for which it was given.

         9.7      DEMAND; PROTEST. Borrower waives demand, protest, notice of
protest, notice of default or dishonor, notice of payment and nonpayment, notice
of any default, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by Bank on which Borrower may in any way be liable.

SILICON VALLEY BANK

    AMENDMENT TO LOAN AND SECURITY AGREEMENT

BORROWER:  DIGIRAD CORPORATION

DATED:     AUGUST 2, 2000

         THIS AMENDMENT TO LOAN AGREEMENT is entered into between SILICON VALLEY
BANK ("Bank") and the borrower named above (the "Borrower"). The Parties agree;
to amend the Loan and Security Agreement between them, dated April 1, 2000, as
amended or otherwise modified from time to time (the "Loan Agreement"), as
follows, effective as of the date hereof. (Capitalized terms used but not
defined in this Amendment, shall have the meanings set forth in the Loan
Agreement.)

         1.     REVISED BORROWING BASE DEFINITION. The definition of "Borrowing
Base" as set forth in section 1 of the Loan Agreement is hereby amended to read
as follows:

         "`Borrowing Base' means an amount equal to

         (i)    Eighty percent (80%) of Eligible Accounts other than Eligible
         Service Accounts; PLUS

         (ii)   the lesser of (A) Fifty percent (50%) of Eligible Service
         Accounts or (B) Forty percent (40%) of all Advances
         outstanding, PROVIDED that a Collateral audit, with results
         satisfactory to the Bank, shall be conducted and be determined
         to be satisfactory to the Bank, in its discretion, prior to
         the requesting or making of any Advances under this clause
         (ii); PLUS

         (iii)  the lesser of (A) Thirty percent (30%) of the value of
         Borrower's Eligible Inventory (valued at the lower of cost or
         wholesale fair market value) or (B) Three Hundred Thousand
         Dollars ($300,000);

         With the above to be determined by Bank with reference to the most
         recent Borrowing Base Certificate delivered by Borrower, PROVIDED
         that it is understood and agreed that the foregoing advance
         percentages may be modified based on audits of Collateral conducted
         on and after the date hereof."

         2. REVISED ELIGIBLE ACCOUNTS. That portion of the definition of
"Eligible Accounts" that now reads as follows:

         "(e)     Accounts with respect to which the account debtor is a
         federal, state, or local governmental entity or any
         department, agency, or instrumentality thereof, except for
         those Accounts of the United States or any department, agency
         or instrumentality thereof as to which the payee has assigned
         its rights to payment thereof to Bank and the assignment has
         been acknowledged, pursuant to the

                                      -1-

         than Accounts arisingfrom accounts debtors consisting of United
         States veteran hospitals, National Institute of Health, state and
         local hospitals or university-affiliated hospitals;"

         IS HEREBY AMENDED  TO READ AS FOLLOWS:

         "(e)     Accounts with respect to which the account debtor is a
         federal, state, or local governmental entity or any
         department, agency, or instrumentality thereof, except for
         those Accounts of the United States or any department, agency
         or instrumentality thereof as to which the payee has assigned
         its rights to payment thereof to Bank and the assignment has

SILICON VALLEY BANK

    AMENDMENT TO LOAN AND SECURITY AGREEMENT

BORROWER:    DIGIRAD CORPORATION

DATED:       DECEMBER 29, 2000

         THIS AMENDMENT TO LOAN AGREEMENT (this "Amendment") is entered into
between SILICON VALLEY BANK ("Bank") and the borrower named above (the
"Borrower"). The Parties agree to amend the Loan and Security Agreement between
them, dated April 1, 2000, as amended or otherwise modified from time to time
(the "Loan Agreement"), as follows, effective as of the date hereof (Capitalized
terms used but not defined in this Amendment, shall have the meanings set forth
in the Loan Agreement.)

         1.       LIMITED CONSENTS.

                  (a)      Anything in the Loan Agreement to the contrary
notwithstanding, Bank hereby consents to each of the following; PROVIDED,
HOWEVER, that no Event of Default (including without limitation in respect of
any financial covenant set forth in the Loan Agreement), or event, condition,
or default that, with the giving of notice, the passage of time, or both,
would be an Event of Default (including without limitation in respect of any
financial covenant set forth in the Loan Agreement), has occurred and is
continuing, both immediately before and immediately after giving effect
thereto:

                           (i)      Borrower's wholly-owned subsidiary, Orion
         Imaging Systems, Inc. ("Orion"), may incur Indebtedness owing to Heller
         Financial in anaggregate amount not to exceed $5,000,000 at any one
         time outstanding (the"Permitted Orion-Heller Indebtedness"). The
         Permitted Orion-Heller Indebtedness shall constitute Permitted
         Indebtedness of Orion.

                           (ii)     Solely to secure the Permitted Orion-Heller
         Indebtedness, Orion may grant a security interest in favor of Heller
         Financial in solely Orion's "accounts" (as such term is defined in the
         Code) (the "Permitted Orion-Heller-Lien"). The Permitted Orion-Heller
         Lien shall constitute a Permitted Lien on the assets of Orion.

                           (iii)    Borrower may guarantee, in favor of Heller
         Financial, up to a maximum of $2,500,000 in respect of the Permitted
         Orion-Heller Indebtedness, which guarantee shall be on an unsecured
         basis (the "Permitted Borrower-Heller Guarantee"). The Permitted
         Borrower-Heller Guarantee shall constitute Permitted Indebtedness of
         Borrower.

                  (b)      It is understood by the parties hereto, however,
that each of the foregoing limited consents of Bank does not constitute a
modification or waiver of any other provision or term of the Loan Agreement
or any related document or of any Event of Default.

                                      -1-
<Page>

         2.       REPRESENTATIONS TRUE. Borrower represents and warrants to
Bank that (a) all representations and warranties in the Loan Agreement, as
amended hereby, are true and correct, and (b) no Event of Default, or event,
condition, or default that, with the giving of notice, the passage of time,
or both, would be an Event of Default, has occurred and is continuing.

         3.       FEE; BANK EXPENSES. Borrower shall pay to Bank a fee of
$1,000 in connection herewith, which shall be in addition to interest and to
all other amounts payable under the Loan Agreement. Without limiting the
generality of the foregoing, Borrower shall pay to Bank all Bank Expenses
incurred in connection with the preparation (and negotiation, if any),
execution, and delivery of this Amendment.

         4.       GENERAL PROVISIONS. This Amendment, the Loan Agreement, any
prior written amendments to the Loan Agreement signed by Bank and the
Borrower, and the other written documents and agreements between Bank and the
Borrower set forth in full all of the representations and agreements of the
parties with respect to the subject matter hereof and supersede all prior
discussions, representations, agreements and understandings between the
parties with respect to the subject hereof. Except as herein expressly
amended, all of the terms and provisions of the Loan Agreement, and all other
documents and agreements between Bank and the Borrower shall continue in full
force and effect and the same are hereby ratified and confirmed. This
Amendment may be executed in any number of counterparts, which when taken
together shall constitute one and the same agreement. Delivery of an executed
counterpart of this Amendment by telefacsimile shall be equally as effective
as delivery of an original executed counterpart of this Amendment.

         In order to induce Silicon to enter into this Agreement and to make
Loans, Borrower represents and warrants to Silicon as follows, and Borrower
covenants that the following representations will continue to be true, and that
Borrower will at all times comply with all of the following covenants:

         3.1      CORPORATE EXISTENCE AND AUTHORITY. Borrower, if a corporation,
is and will continue to be, duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation. Borrower is
and will continue to be qualified and licensed to do business in all
jurisdictions in which any failure to do so would have a material adverse effect
on Borrower. The execution, delivery and performance by Borrower of this
Agreement, and all other documents contemplated hereby (i) have been duly and
validly authorized, (ii) are enforceable against Borrower in accordance with
their terms (except as enforcement may be limited by equitable principles and by
bankruptcy, insolvency, reorganization, moratorium or similar laws relating to
creditors' rights generally), and (iii) do not violate Borrower's articles or
certificate of incorporation, or Borrower's by-laws, or any law or any material
agreement or instrument which is binding upon Borrower or its property, and (iv)
do not constitute grounds for acceleration of any material indebtedness or
obligation under any material agreement or instrument which is binding upon
Borrower or its property.

         3.2      NAME, TRADE NAMES AND STYLES. The name of Borrower set forth
in the heading to this Agreement is its correct name. Listed on the Schedule are
all prior names of Borrower and all of Borrower's present and prior trade names.
Borrower shall give Silicon 30 days' prior written notice before changing its
name or doing business under any other name. Borrower has complied, and will in
the future comply, with all laws relating to the conduct of business under a
fictitious business name.

         3.3      PLACE OF BUSINESS, LOCATION OF COLLATERAL. The address set
forth in the heading to this Agreement is Borrower's chief executive office. In
addition, Borrower has places of business and Collateral is located only at the
locations set forth on the Schedule. Borrower will give Silicon at least 30 days
prior written notice before opening any additional place of business, changing
its chief executive office, or moving any of the Collateral to a location other
than Borrower's Address or one of the locations set forth on the Schedule.*

         *NOTWITHSTANDING THE FOREGOING, BORROWER REPRESENTS AND WARRANTS THAT
ALL OF BORROWER'S LOCATIONS OUTSIDE OF CALIFORNIA ARE SALES OFFICES ONLY WITH
LITTLE OR NO ASSETS. ADDITIONALLY, DURING THE TERM OF THIS AGREEMENT, BORROWER
SHALL NOT TRANSFER ANY ASSETS TO ANY SUBSIDIARY.

         3.4      TITLE TO COLLATERAL; PERMITTED LIENS. Borrower is now, and
will at all times in the future be, the sole owner of all the Collateral, except
for items of Equipment which are leased by Borrower. The Collateral now is and
will remain free and clear of any and all liens, charges, security interests,

                                      -2-
<Page>

encumbrances and adverse claims, except for Permitted Liens. Silicon now has,
and will continue to have, a first-priority perfected and enforceable security
interest in all of the Collateral, subject only to the Permitted Liens, and
Borrower will at all times defend Silicon and the Collateral against all claims
of others. None of the Collateral now is or will be affixed to any real property
in such a manner, or with such intent, as to become a fixture. Borrower is not
and will not become a lessee under any real property lease pursuant to which the
lessor may obtain any rights in any of the Collateral and no such lease now
prohibits, restrains, impairs or will prohibit, restrain or impair Borrower's
right to remove any Collateral from the leased premises. Whenever any Collateral
is located upon premises in which any third party has an interest (whether as
owner, mortgagee, beneficiary under a deed of trust, lien or otherwise),
Borrower shall, whenever requested by Silicon, use its best efforts to cause
such third party to execute and deliver to Silicon, in form acceptable to
Silicon, such waivers and subordinations as Silicon shall specify, so as to
ensure that Silicon's rights in the Collateral are, and will continue to be,
superior to the rights of any such third party. Borrower will keep in full force
and effect, and will comply with all the terms of, any lease of real property
where any of the Collateral now or in the future may be located.

         3.5      MAINTENANCE OF COLLATERAL. Borrower will maintain the
Collateral in good working condition, and Borrower will not use the Collateral
for any unlawful purpose. Borrower will immediately advise Silicon in writing of
any material loss or damage to the Collateral.

         3.6      BOOKS AND RECORDS. Borrower has maintained and will maintain
at Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

         3.7      FINANCIAL CONDITION, STATEMENTS AND REPORTS. All financial
statements now or in the future delivered to Silicon have been, and will be,
prepared in conformity with generally accepted accounting principles and now and
in the future will completely and accurately reflect the financial condition of
Borrower, at the times and for the periods therein stated. Between the last date
covered by any such statement provided to Silicon and the date hereof, there has
been no material adverse change in the financial condition or business of
Borrower. Borrower is now and will continue to be solvent.

         3.8      TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower has
timely filed, and will timely file, all tax returns and reports required by
foreign, federal, state and local law, and Borrower has timely paid, and will
timely pay, all foreign, federal, state and local taxes, assessments, deposits
and contributions now or in the future owed by Borrower. Borrower may, however,
defer payment of any contested taxes, provided that Borrower (i) in good faith
contests Borrower's obligation to pay the taxes by appropriate proceedings
promptly and diligently instituted and conducted, (ii) notifies Silicon in
writing of the commencement of, and any material development in, the
proceedings, and (iii) posts bonds or takes any other steps required to keep the
contested taxes from becoming a lien upon any of the Collateral. Borrower is
unaware of any claims or adjustments proposed for any of Borrower's prior tax
years which could result in additional taxes becoming due and payable by
Borrower. Borrower has paid, and shall continue to pay all amounts necessary to
fund all present and future pension, profit sharing and deferred compensation
plans in accordance with their terms, and Borrower has not and will not withdraw
from participation in, permit partial or complete termination of, or permit the
occurrence of any other event with respect to, any such plan which could result
in any liability of Borrower, including any liability to the Pension Benefit
Guaranty Corporation or its successors or any other governmental agency.
Borrower shall, at all times, utilize the services of an outside payroll service
providing for the automatic deposit of all payroll taxes payable by Borrower.

         3.9      COMPLIANCE WITH LAW. Borrower has complied, and will comply,
in all material respects, with all provisions of all foreign, federal, state and
local laws and regulations relating to Borrower, including, but not limited to,
those relating to Borrower's ownership of real or personal property, the conduct
and licensing of Borrower's business, and all environmental matters.

         3.10     LITIGATION. Except as disclosed in the Schedule, there is no
claim, suit, litigation, proceeding or investigation pending or (to best of
Borrower's knowledge) threatened by or against or affecting Borrower in any
court or before any governmental agency (or any basis therefor known to
Borrower) which may result, either separately or in the aggregate, in any
material adverse change in the financial condition or business of Borrower, or
in any material impairment in the ability of Borrower to carry on its business
in substantially the same manner as it is now being conducted. Borrower will
promptly inform Silicon in writing of any claim, proceeding,

                                      -3-
<Page>

litigation or investigation in the future threatened or instituted by or against
Borrower involving any single claim of $50,000 or more, or involving $100,000 or
more in the aggregate.

         3.11     USE OF PROCEEDS. All proceeds of all Loans shall be used
solely for lawful business purposes. Borrower is not purchasing or carrying any
"margin stock" (as defined in Regulation U of the Board of Governors of the
Federal Reserve System) and no part of the proceeds of any Loan will be used to
purchase or carry any "margin stock" or to extend credit to others for the
purpose of purchasing or carrying any "margin stock."

4.       RECEIVABLES.

         4.1      REPRESENTATIONS RELATING TO RECEIVABLES. Borrower represents
and warrants to Silicon as follows: Each Receivable with respect to which Loans
are requested by Borrower shall, on the date each Loan is requested and made,
(i) represent an undisputed bona fide existing unconditional obligation of the
Account Debtor created by the sale, delivery, and acceptance of goods or the
rendition of services in the ordinary course of Borrower's business, and (ii)
meet the Minimum Eligibility Requirements set forth in Section 8 below.

         4.2      REPRESENTATIONS RELATING TO DOCUMENTS AND LEGAL COMPLIANCE.
Borrower represents and warrants to Silicon as follows: All statements made and
all unpaid balances appearing in all invoices, instruments and other documents
evidencing the Receivables are and shall be true and correct and all such
invoices, instruments and other documents and all of Borrower's books and
records are and shall be genuine and in all respects what they purport to be,
and all signatories and endorsers have the capacity to contract. All sales and
other transactions underlying or giving rise to each Receivable shall fully
comply with all applicable laws and governmental rules and regulations. All
signatures and endorsements on all documents, instruments, and agreements
relating to all Receivables are and shall be genuine, and all such documents,
instruments and agreements are and shall be legally enforceable in accordance
with their terms.

         4.3      SCHEDULES AND DOCUMENTS RELATING TO RECEIVABLES. Borrower
shall deliver to Silicon transaction reports and loan requests, schedules and
assignments of all Receivables, and schedules of collections, all on Silicon's
standard forms; provided, however, that Borrower's failure to execute and
deliver the same shall not affect or limit Silicon's security interest and other
rights in all of Borrower's Receivables, nor shall Silicon's failure to advance
or lend against a specific Receivable affect or limit Silicon's security
interest and other rights therein. Loan requests received after 12:00 Noon will
not be considered by Silicon until the next Business Day. Together with each
such schedule and assignment, or later if requested by Silicon, Borrower shall
furnish Silicon with copies (or, at Silicon's request, originals) of all
contracts, orders, invoices, and other similar documents, and all original
shipping instructions, delivery receipts, bills of lading, and other evidence of
delivery, for any goods the sale or disposition of which gave rise to such
Receivables, and Borrower warrants the genuineness of all of the foregoing.
Borrower shall also furnish to Silicon an aged accounts receivable trial balance
in such form and at such intervals as Silicon shall request. In addition,
Borrower shall deliver to Silicon the originals of all instruments, chattel
paper, security agreements, guarantees and other documents and property
evidencing or securing any Receivables, immediately upon receipt thereof and in
the same form as received, with all necessary indorsements, all of which shall
be with recourse. Borrower shall also provide Silicon with copies of all credit
memos within two days after the date issued.

         4.4      COLLECTION OF RECEIVABLES. Borrower shall have the right to
collect all Receivables, unless and until a Default or an Event of Default has
occurred. Borrower shall hold all payments on, and proceeds of, Receivables in
trust for Silicon, and Borrower shall immediately deliver all such payments and
proceeds to Silicon in their original form, duly endorsed in blank, to be
applied to the Obligations in such order as Silicon shall determine. Silicon
may, in its discretion, require that all proceeds of Collateral be deposited by
Borrower into a lockbox account, or such other "blocked account" as Silicon may
specify, pursuant to a blocked account agreement in such form as Silicon may
specify. Silicon or its designee may, at any time, notify Account Debtors that
the Receivables have been assigned to Silicon.

         4.5.     REMITTANCE OF PROCEEDS. All proceeds arising from the
disposition of any Collateral shall be delivered, in kind, by Borrower to
Silicon in the original form in which received by Borrower not later than the
following Business Day after receipt by Borrower, to be applied to the
Obligations in such order as Silicon shall determine; provided that, if no
Default or Event of Default has occurred, Borrower shall not be obligated to
remit to Silicon the proceeds of the sale of worn out or obsolete equipment
disposed of by Borrower in good faith in an arm's length transaction for an
aggregate purchase price of

                                      -4-
<Page>

$25,000 or less (for all such transactions in any fiscal year). Borrower agrees
that it will not commingle proceeds of Collateral with any of Borrower's other
funds or property, but will hold such proceeds separate and apart from such
other funds and property and in an express trust for Silicon. Nothing in this
Section limits the restrictions on disposition of Collateral set forth elsewhere
in this Agreement.

         4.6      DISPUTES. Borrower shall notify Silicon promptly of all
disputes or claims relating to Receivables. Borrower shall not forgive
(completely or partially), compromise or settle any Receivable for less than
payment in full, or agree to do any of the foregoing, except that Borrower may
do so, provided that: (i) Borrower does so in good faith, in a commercially
reasonable manner, in the ordinary course of business, and in arm's length
transactions, which are reported to Silicon on the regular reports provided to
Silicon; (ii) no Default or Event of Default has occurred and is continuing; and
(iii) taking into account all such discounts settlements and forgiveness, the
total outstanding Loans will not exceed the Credit Limit. Silicon may, at any
time after the occurrence of an Event of Default, settle or adjust disputes or
claims directly with Account Debtors for amounts and upon terms which Silicon
considers advisable in its reasonable credit judgment and, in all cases, Silicon
shall credit Borrower's Loan account with only the net amounts received by
Silicon in payment of any Receivables.

         4.7      RETURNS. Provided no Event of Default has occurred and is
continuing, if any Account Debtor returns any Inventory to Borrower in the
ordinary course of its business, Borrower shall promptly determine the reason
for such return and promptly issue a credit memorandum to the Account Debtor in
the appropriate amount (sending a copy to Silicon). In the event any attempted
return occurs after the occurrence of any Event of Default, Borrower shall (i)
hold the returned Inventory in trust for Silicon, (ii) segregate all returned
Inventory from all of Borrower's other property, (iii) conspicuously label the
returned Inventory as Silicon's property, and (iv) immediately notify Silicon of
the return of any Inventory, specifying the reason for such return, the location
and condition of the returned Inventory, and on Silicon's request deliver such
returned Inventory to Silicon.

         4.8      VERIFICATION. Silicon may, from time to time, verify directly
with the respective Account Debtors the validity, amount and other matters
relating to the Receivables, by means of mail, telephone or otherwise, either in
the name of Borrower or Silicon or such other name as Silicon may choose.

         4.9      NO LIABILITY. Silicon shall not under any circumstances be
responsible or liable for any shortage or discrepancy in, damage to, or loss or
destruction of, any goods, the sale or other disposition of which gives rise to
a Receivable, or for any error, act, omission, or delay of any kind occurring in
the settlement, failure to settle, collection or failure to collect any
Receivable, or for settling any Receivable in good faith for less than the full
amount thereof, nor shall Silicon be deemed to be responsible for any of
Borrower's obligations under any contract or agreement giving rise to a
Receivable. Nothing herein shall, however, relieve Silicon from liability for
its own gross negligence or willful misconduct.

5.       ADDITIONAL DUTIES OF BORROWER.

         5.1      FINANCIAL AND OTHER COVENANTS. Borrower shall at all times
comply with the financial and other covenants set forth in the Schedule.

         5.2      INSURANCE. Borrower shall, at all times insure all of the
tangible personal property Collateral and carry such other business insurance,
with insurers reasonably acceptable to Silicon, in such form and amounts as
Silicon may reasonably require, and Borrower shall provide evidence of such
insurance to Silicon, so that Silicon is satisfied that such insurance is, at
all times, in full force and effect. All such insurance policies shall name
Silicon as an additional loss payee, and shall contain a lenders loss payee
endorsement in form reasonably acceptable to Silicon. Upon receipt of the
proceeds of any such insurance, Silicon shall apply such proceeds in reduction
of the Obligations as Silicon shall determine in its sole discretion, except
that, provided no Default or Event of Default has occurred and is continuing,
Silicon shall release to Borrower insurance proceeds with respect to Equipment
totaling less than $100,000, which shall be utilized by Borrower for the
replacement of the Equipment with respect to which the insurance proceeds were
paid. Silicon may require reasonable assurance that the insurance proceeds so
released will be so used. If Borrower fails to provide or pay for any insurance,
Silicon may, but is not obligated to, obtain the same at Borrower's expense.
Borrower shall promptly deliver to Silicon copies of all reports made to
insurance companies.

         5.3      REPORTS. Borrower, at its expense, shall provide Silicon with
the written reports set forth in

                                      -5-
<Page>

the Schedule, and such other written reports with respect to Borrower (including
budgets, sales projections, operating plans and other financial documentation),
as Silicon shall from time to time reasonably specify.

         5.4      ACCESS TO COLLATERAL, BOOKS AND RECORDS. At reasonable times,
and on one Business Day's notice, Silicon, or its agents, shall have the right
to inspect the Collateral, and the right to audit and copy Borrower's books and
records. Silicon shall take reasonable steps to keep confidential all
information obtained in any such inspection or audit, but Silicon shall have the
right to disclose any such information to its auditors, regulatory agencies, and
attorneys, and pursuant to any subpoena or other legal process. The foregoing
inspections and audits shall be at Borrower's expense and the charge therefor
shall be $650 per person per day (or such higher amount as shall represent
Silicon's then current standard charge for the same), plus reasonable out of
pocket expenses. Borrower will not enter into any agreement with any accounting
firm, service bureau or third party to store Borrower's books or records at any
location other than Borrower's Address, without first obtaining Silicon's
written consent, which may be conditioned upon such accounting firm, service
bureau or other third party agreeing to give Silicon the same rights with
respect to access to books and records and related rights as Silicon has under
this Loan Agreement.

         5.5      NEGATIVE COVENANTS. Except as may be permitted in the
Schedule, Borrower shall not, without Silicon's prior written consent, do any of
the following: (i) merge or consolidate with another corporation or entity; (ii)
acquire any assets, except in the ordinary course of business; (iii) enter into
any other transaction outside the ordinary course of business*; (iv) sell or
transfer any Collateral, except for the sale of finished Inventory in the
ordinary course of Borrower's business, and except for the sale of obsolete or
unneeded Equipment in the ordinary course of business; (v) store any Inventory
or other Collateral with any warehouseman or other third party; (vi) sell any
Inventory on a sale-or-return, guaranteed sale, consignment, or other contingent
basis; (vii) make any loans of any money or other assets; (viii) incur any
debts, outside the ordinary course of business, which would have a material,
adverse effect on Borrower or on the prospect of repayment of the Obligations;
(ix) guarantee or otherwise become liable with respect to the obligations of
another party or entity; (x) pay or declare any dividends on Borrower's stock
(except for dividends payable solely in stock of Borrower); (xi) redeem, retire,
purchase or otherwise acquire, directly or indirectly, any of Borrower's stock;
(xii) make any change in Borrower's capital structure which would have a
material adverse effect on Borrower or on the prospect of repayment of the
Obligations; or (xiii) pay total compensation, including salaries, fees,
bonuses, commissions, and all other payments, whether directly or indirectly, in
money or otherwise, to Borrower's executives, officers and directors (or any
relative thereof) in an amount in excess of the amount set forth on the
Schedule; or (xiv) dissolve or elect to dissolve. Transactions permitted by the
foregoing provisions of this Section are only permitted if no Default or Event
of Default would occur as a result of such transaction.

         *(EXCEPT FOR A PUBLIC OFFERING OF BORROWER'S EQUITY SECURITIES)

         5.6      LITIGATION COOPERATION. Should any third-party suit or
proceeding be instituted by or against Silicon with respect to any Collateral or
in any manner relating to Borrower, Borrower shall, without expense to Silicon,
make available Borrower and its officers, employees and agents and Borrower's
books and records, to the extent that Silicon may deem them reasonably necessary
in order to prosecute or defend any such suit or proceeding.

         5.7      FURTHER ASSURANCES. Borrower agrees, at its expense, on
request by Silicon, to execute all documents and take all actions, as Silicon,
may deem reasonably necessary or useful in order to perfect and maintain
Silicon's perfected security interest in the Collateral, and in order to fully
consummate the transactions contemplated by this Agreement.

6.       TERM.

         6.1      MATURITY DATE. This Agreement shall continue in effect until
the maturity date set forth on the Schedule (the "Maturity Date"), subject to
Section 6.3 below.

         6.2      EARLY TERMINATION. This Agreement may be terminated prior to
the Maturity Date as follows: (i) by Borrower, effective three Business Days
after written notice of termination is given to Silicon; or (ii) by Silicon at
any time after the occurrence of an Event of Default, without notice, effective
immediately. If this Agreement is terminated by Borrower or by Silicon under
this Section 6.2, Borrower shall pay to Silicon a termination fee in an amount
equal to* provided that no termination fee shall be charged if the credit
facility hereunder is

                                      -6-
<Page>

replaced with a new facility from another division of Silicon Valley Bank. The
termination fee shall be due and payable on the effective date of termination
and thereafter shall bear interest at a rate equal to the highest rate
applicable to any of the Obligations.

*$5,000 PER MONTH FOR THE NUMBER OF MONTHS REMAINING (INCLUDING ANY PARTIAL
MONTHS) UNTIL THE MATURITY DATE,

         6.3      PAYMENT OF OBLIGATIONS. On the Maturity Date or on any earlier
effective date of termination, Borrower shall pay and perform in full all
Obligations, whether evidenced by installment notes or otherwise, and whether or
not all or any part of such Obligations are otherwise then due and payable.
Without limiting the generality of the foregoing, if on the Maturity Date, or on
any earlier effective date of termination, there are any outstanding Letters of
Credit issued by Silicon or issued by another institution based upon an
application, guarantee, indemnity or similar agreement on the part of Silicon,
then on such date Borrower shall provide to Silicon cash collateral in an amount
equal to the face amount of all such Letters of Credit plus all interest, fees
and cost due or to become due in connection therewith, to secure all of the
Obligations relating to said Letters of Credit, pursuant to Silicon's then
standard form cash pledge agreement. Notwithstanding any termination of this
Agreement, all of Silicon's security interests in all of the Collateral and all
of the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided
that, without limiting the fact that Loans are subject to the discretion of
Silicon, Silicon may, its sole discretion refuse to make any further Loans after
termination. No termination shall in any way affect or impair any right or
remedy of Silicon, nor shall any such termination relieve Borrower of any
Obligation to Silicon, until all of the Obligations have been paid and performed

         7.2      REMEDIES. Upon the occurrence of any Event of Default, and at
any time thereafter, Silicon, at its option, and without notice or demand of any
kind (all of which are hereby expressly waived by Borrower), may do any one or
more of the following: (a) Cease making Loans or otherwise extending credit to
Borrower under this Agreement or any other document or agreement; (b) Accelerate
and declare all or any part of the Obligations to be immediately due, payable,
and performable, notwithstanding any deferred or installment payments allowed by

any or all of the Collateral wherever it may be found, and for that purpose
Borrower hereby authorizes Silicon without judicial process to enter onto any of
Borrower's premises without interference to search for, take possession of,
keep, store, or remove any of the Collateral, and remain on the premises or
cause a custodian to remain on the premises in exclusive control thereof,
without charge for so long as Silicon deems it reasonably necessary in order to
complete the enforcement of its rights under this Agreement or any other
agreement; provided, however, that should Silicon seek to take possession of any
of the Collateral by Court process, Borrower hereby irrevocably waives: (i) any
bond and any surety or security relating thereto required by any statute, court
rule or otherwise as an incident to such possession; (ii) any demand for
possession prior to the commencement of any suit or action to recover possession
thereof; and (iii) any requirement that Silicon retain possession of, and not

condition at the time Silicon obtains possession of it or after further

adjourn any such sale from time to time without notice other than oral
announcement at the time scheduled for sale. Silicon shall have the right to
conduct such disposition on Borrower's premises without charge, for such time or
times as Silicon deems reasonable, or on Silicon's premises, or elsewhere and
the Collateral need not be located at the place of disposition. Silicon may
directly or through any affiliated company purchase or lease any Collateral at
any such public disposition, and if permissible under applicable law, at any
private disposition. Any sale or other disposition of Collateral shall not
relieve Borrower of any liability Borrower may have if any Collateral is
defective as to title or physical condition or otherwise at the time of sale;
(g) Demand payment of, and collect any Receivables and General Intangibles
comprising Collateral and, in connection therewith, Borrower irrevocably
authorizes Silicon to endorse or sign Borrower's name on all collections,
receipts, instruments and other documents, to take possession

and shall bear interest at a rate equal to the highest interest rate applicable
to any of the Obligations. Without limiting any of Silicon's rights and
remedies, from and after the occurrence of any Event of Default, the interest
rate applicable to the Obligations shall be increased by an additional four
percent per annum.

         7.3      STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS. Borrower
and Silicon agree that a sale or other disposition (collectively, "sale") of any
Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable: (i) Notice of the sale is given to
Borrower at least* days prior to the sale, and, in the case of a public sale,
notice of the sale is, published at least* days before the sale in a newspaper
of general circulation in the county where the sale is to be conducted; (ii)
Notice of the sale describes the collateral in general, non-specific terms;

check or wire transfer is required; (vi) With respect to any sale of any of the
Collateral, Silicon may (but is not obligated to) direct any prospective
purchaser to ascertain directly from Borrower any and all information concerning
the same. Silicon shall be free to employ other methods of noticing and selling
the Collateral, in its discretion, if they are commercially reasonable.

attorneys or agents) at any time, at its option, but without obligation, with or
without notice to Borrower, and at Borrower's expense, to do any or all of the
following, in Borrower's name or otherwise, but Silicon agrees to exercise the
following powers in a commercially reasonable manner: (a) Execute on behalf of
Borrower any documents that Silicon may, in its sole discretion, deem advisable
in order to perfect and maintain Silicon's security interest in the Collateral,
or in order to exercise a right of Borrower or Silicon, or in order to fully
consummate all the transactions contemplated under this Agreement, and all other
present and future agreements; (b) Execute on behalf of Borrower any document
exercising, transferring or assigning any option to purchase, sell or otherwise
dispose of or to lease (as lessor or lessee) any real or personal property which
is part of Silicon's Collateral or in which Silicon has an interest; (c) Execute
on behalf of Borrower, any invoices relating to any Receivable, any draft

interest and adverse claim in or to any of the Collateral, or any judgment based

having custody or control of any books or records belonging to, or relating to,
Borrower to give Silicon the same rights of access and other rights with respect
thereto as Silicon has under this Agreement; and (k) Take any action or pay any
sum required of Borrower pursuant to this Agreement and any other present or
future agreements. Any and all reasonable sums paid and any and all reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by

Obligations, shall be payable on demand, and shall bear interest at a rate equal
to the

                                      -9-
<Page>

highest interest rate applicable to any of the Obligations. In no event shall
Silicon's rights under the foregoing power of attorney or any of Silicon's other
rights under this Agreement be deemed to indicate that Silicon is in control of
the business, management or properties of Borrower.

         7.5      APPLICATION OF PROCEEDS. All proceeds realized, as the result
of any sale of the Collateral shall be applied by Silicon first to the
reasonable costs, expenses, liabilities, obligations and attorneys' fees
incurred by Silicon in the exercise of its rights under this Agreement, second
to the interest due upon any of the Obligations, and third to the principal of
the Obligations, in such order as Silicon shall determine in its sole
discretion. Any surplus shall be paid to Borrower or other persons legally
entitled thereto; Borrower shall remain liable to Silicon for any deficiency.
If, Silicon, in its sole discretion, directly or indirectly enters into a
deferred payment or other credit transaction with any purchaser at any sale of
Collateral, Silicon shall have the option, exercisable at any time, in its sole
discretion, of either reducing the Obligations by the principal amount of
purchase price or deferring the reduction of the Obligations until the actual
receipt by Silicon of the cash therefor.

         7.6      REMEDIES CUMULATIVE. In addition to the rights and remedies
set forth in this Agreement, Silicon shall have all the other rights and
remedies accorded a secured party under the California Uniform Commercial Code
and under all other applicable laws, and under any other instrument or agreement
now or in the future entered into between Silicon and Borrower, and all of such
rights and remedies are cumulative and none is exclusive. Exercise or partial
exercise by Silicon of one or more of its rights or remedies shall not be deemed
an election, nor bar Silicon from subsequent exercise or partial exercise of any
other rights or remedies. The failure or delay of Silicon to exercise any rights
or remedies shall not operate as a waiver thereof, but all rights and remedies
shall continue in full force and effect until all of the Obligations have been
fully paid and performed.

Obligations may be applied, and in Silicon's sole discretion, reversed and
re-applied, to the Obligations, in such order and manner as Silicon shall

monetary Obligations to Borrower's Deposit Accounts maintained with Silicon.

         9.4      MONTHLY ACCOUNTINGS. Silicon shall provide Borrower monthly
with an account of advances, charges, expenses and payments made pursuant to
this Agreement. Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications of
payments made and corrections of errors discovered by Silicon), unless Borrower
notifies Silicon in writing to the contrary within thirty days after each
account is rendered, describing the nature of any alleged errors or admissions.

require Borrower to strictly comply with any of the provisions of this Agreement
or any other present or future agreement between Borrower and Silicon shall not
waive or diminish any right of Silicon later to demand and receive strict
compliance therewith. Any waiver of any default shall not waive or affect any
other default, whether prior or subsequent, and whether or not similar. None of
the provisions of this Agreement or any other agreement now or in the future
executed by Borrower and delivered to Silicon shall be deemed to have been
waived by any act or knowledge of Silicon or its agents or employees, but only
by a specific written waiver signed by an authorized officer of Silicon and
delivered to Borrower. Borrower waives demand, protest, notice of protest and
notice of default or dishonor, notice of payment and nonpayment, release,
compromise, settlement, extension or renewal of any commercial paper,
instrument, account, General Intangible, document or guaranty at any time held
by Silicon on which Borrower is or may in any way be liable, and notice of any
action taken by Silicon, unless expressly required by this Agreement.

         9.9      NO LIABILITY FOR ORDINARY NEGLIGENCE. Neither Silicon, nor any
of its directors, officers, employees, agents, attorneys or any other Person
affiliated with or representing Silicon shall be liable for any claims, demands,
losses or damages, of any kind whatsoever, made, claimed, incurred or suffered
by Borrower or any other party through the ordinary negligence of Silicon, or
any, of its directors, officers, employees, agents, attorneys or any other
Person affiliated with or representing Silicon, but nothing herein shall relieve
Silicon from liability for its own gross negligence or willful misconduct.

         9.10     AMENDMENT. The terms and provisions of this Agreement may not
be waived or amended, except in a writing executed by Borrower and a duly

all reasonable attorneys' fees and all filing, recording, search, title
insurance, appraisal, audit, and other reasonable costs incurred by Silicon,
pursuant to, or in connection with, or relating to this Agreement (whether or
not a lawsuit is filed), including, but not limited to, any reasonable
attorneys' fees and costs Silicon incurs in order to do the following: prepare

or otherwise enforce Silicon's security interest in, the Collateral; and
otherwise represent Silicon in any litigation relating to Borrower. IN
SATISFYING BORROWER'S OBLIGATION HEREUNDER TO REIMBURSE SILICON FOR ATTORNEYS
FEES, BORROWER MAY, FOR CONVENIENCE, ISSUE CHECKS DIRECTLY TO SILICON'S
ATTORNEYS, LEVY, SMALL & LALLAS, BUT BORROWER ACKNOWLEDGES AND AGREES THAT LEVY,
SMALL & LALLAS IS REPRESENTING ONLY SILICON AND NOT BORROWER IN CONNECTION WITH
THIS AGREEMENT. If either Silicon or Borrower files any lawsuit against the
other predicated on a breach of this Agreement, the prevailing party in such
action shall be entitled to recover its reasonable costs and attorneys' fees,
including (but not limited to) reasonable attorneys' fees and costs incurred in
the enforcement of, execution upon or defense of any order, decree, award or
judgment. All attorneys' fees and costs to which Silicon may be entitled

Obligations, shall be due on demand, and shall bear interest at a rate equal to
the highest interest rate applicable to any of the Obligations.

         9.13     BENEFIT OF AGREEMENT. The provisions of this Agreement shall
be binding upon and inure to the benefit of the respective successors, assigns,
heirs, beneficiaries and representatives of Borrower and Silicon; provided,
however, that Borrower may not assign or transfer any of its rights under this
Agreement without the prior written consent of Silicon, and any prohibited
assignment shall be void. No consent by Silicon to any assignment shall release
Borrower from its liability for the Obligations.

         9.14     JOINT AND SEVERAL LIABILITY. If Borrower consists of more than
one Person, their liability shall be joint and several, and the compromise of
any claim with, or the re-lease of, any Borrower shall not constitute a
compromise with, or a release of, any other Borrower.

         9.15     LIMITATION OF ACTIONS. Any claim or cause of action by
Borrower against Silicon, its directors, officers, employees, agents,
accountants or attorneys, based upon, arising from, or relating to this Loan
Agreement, or any other present or future document or agreement, or any other
transaction contemplated hereby or thereby or relating hereto or thereto, or any
other matter, cause or thing whatsoever, occurred, done, omitted or suffered to
be done by Silicon, its directors, officers, employees, agents, accountants or
attorneys, shall be barred unless asserted by Borrower by the commencement of an

claim or cause of action, or any part thereof, is based, and the service of a
summons and complaint on an officer of Silicon, or on any other person
authorized to accept service on behalf of Silicon, within thirty (30) days
thereafter. Borrower agrees that such** period is a reasonable and sufficient
time for Borrower to investigate and act upon any such claim or cause of action.
The** period provided herein shall not be waived, tolled, or extended except by
the written consent of Silicon in its sole discretion. This provision shall
survive any termination of this Loan Agreement or any other present or future
agreement.

                                   SCHEDULE TO

                           LOAN AND SECURITY AGREEMENT

BORROWER:         DIGIRAD CORPORATION
ADDRESS:          9350 TRADE PLACE
                  SAN DIEGO, CA 92126

DATED:            JULY 31, 2001

This Schedule forms an integral part of the Loan and Security Agreement between
Silicon Valley Bank and the above-borrower of even date.

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

1.       CREDIT LIMIT
         (Section 1.1):

                  An amount not to exceed the lesser of a total of $4,300,000 at
                  any one time outstanding (the "Maximum Credit Limit"), or the
                  sum of (a) and (b) below:

                           (a)      75% (the "Percentage Advance Rate") of the
                                    amount of Borrower's Eligible Receivables
                                    (as defined in Section 8 above), plus

                           (b)      an amount not to exceed the lesser of:

                                    (1)      25% of the value of Borrower's
                                             Eligible Inventory (as defined in
                                             Section 8 above), calculated at the
                                             lower of cost or market value and
                                             determined on a first-in, first-out
                                             basis, or

                                    (2)      50% of the amount of Borrower's
                                             Eligible Receivables (as defined in
                                             Section 8 above), or

                                    (3)      $300,000.

                  The foregoing Percentage Advance Rate is typically based on
                  the quality of the Receivables and attendant Dilution as
                  follows: up to 85% Percentage Advance Rate with 5% Dilution;
                  up to 80% Percentage Advance Rate with Dilution over 5 % but
                  less than 10%; up to 75% Percentage

                                       1
<Page>

                  Advance Rate when Dilution is over 10% but less than 15%. If
                  Dilution exceeds 15%, a reserve is established for the
                  dilution factor rounded up to the nearest whole number then
                  multiplied by a factor of up to 75%.

                  As used above, "Dilution" means all deductions from
                  Receivables by Account Debtors of Borrower, other than those
                  arising from payment thereof, and includes without limitation
                  deductions arising from advertising and other allowances,
                  credit memos, returns, bad debts, and all other deductions, as
                  determined by Silicon's audit and for such period as Silicon
                  shall determine. Changes in the Percentage Advance Rate based
                  on Dilution shall go into effect when Silicon has determined
                  the amount of the Dilution and given written notice to the
                  Borrower of the change in the Percentage Advance Rate. If, as
                  a result of a decrease in the Percentage Advance Rate, the
                  total Loans and other Obligations exceed the Credit Limit, the
                  Borrower shall pay the excess to Silicon in accordance with
                  the terms of this Agreement.

                  Moreover, prior to any increase in the Percentage Advance Rate
                  going into effect, the delinquency rate with respect to the
                  Borrower's Receivables must be satisfactory to Silicon in its
                  sole discretion.

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

2.       INTEREST.

         INTEREST RATE (Section 1.2):

                  A rate equal to the "Prime Rate" in effect from time to time,
                  plus 2.0% per annum. Interest shall be calculated on the basis
                  of a 360-day year for the actual number of days elapsed.
                  "Prime Rate" means the rate announced from time to time by
                  Silicon as its "prime rate;" it is a base rate upon which
                  other rates charged by Silicon are based, and it is not
                  necessarily the best rate available at Silicon. The interest
                  rate applicable to the Obligations shall change on each date
                  there is a change in the Prime Rate.

         MINIMUM MONTHLY
         INTEREST (Section 1.2):

                  $5,000 per month.

                  $500, per month, payable in arrears (prorated for any partial
                  month at the beginning and at termination of this Agreement).

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

4.       MATURITY DATE
         (Section 6.1):

                  One year from the date of this Agreement.

                           indebtedness of Borrower to its officers, directors
                           and shareholders ("Inside Debt") shall, at all times,
                           be subordinated to the Obligations pursuant to a
                           subordination agreement on Silicon's standard form.
                           Borrower represents and warrants that there is no
                           Inside Debt presently outstanding, except for the
                           following: NONE. Prior to incurring any Inside Debt
                           in the future, Borrower shall cause the person to
                           whom such Inside Debt will be owed to execute and

                  (3)      WARRANTS. Borrower shall provide Silicon with
                           five-year warrants to purchase 42,490 shares of

                  (4)      FUTURE WARRANTS. In the event the Maximum Credit
                           Limit (as defined above) increases, Borrower agrees
                           that it shall issue to Silicon additional warrants to
                           purchase stock of Borrower, on Silicon's standard
                           form with such modifications as are acceptable to
                           Silicon in its sale discretion, for an amount of
                           shares equal to 3% of the increase in the Maximum
                           Credit Limit divided by the initial exercise price of
                           such warrant. The class of stock and initial exercise
                           price shall be determined at or about the time of
                           such proposed increase in the Maximum Credit Limit.

<Page>

ASSIGNMENT TO SECURE ASSIGNOR'S OBLIGATIONS TO ASSIGNEE UNDER THE LOAN
AGREEMENT.

         2.       AUTHORIZATION AND REQUEST. Assignor authorizes and requests
that the Register of Copyrights and the Commissioner of Patents and Trademarks
record this conditional assignment.

         3.       COVENANTS AND WARRANTIES. Assignor represents, warrants,
covenants and agrees as follows:

                  (a)      Assignor is now the sole owner of the Collateral,
except for non-exclusive licenses granted by Assignor to its customers in the
ordinary course of business.

                  (b)      Listed on Exhibits A-1 and A-2 are all copyrights
owned by Assignor, in which Assignor has an interest, or which are used in
Assignor's business.

                  (c)      Each employee, agent and/or independent contractor
who has participated in the creation of the property constituting the Collateral
has either executed an assignment of his or her rights of authorship to Assignor
or is an employee of Assignor acting within the scope of his or her employment
and was such an employee at the time of said creation.

                  (d)      All of Assignor's present and future software,
computer programs and other works of authorship subject to United States
copyright protection, the sale, licensing or other disposition of which results
in royalties receivable, license fees receivable, accounts receivable or other
sums owing to Assignor (collectively, "Receivables"), have been and shall be
registered with the United States Copyright Office prior to the date Assignor
requests or accepts any loan from Assignee with respect to such Receivables and
prior to the date Assignor includes any such Receivables in any accounts
receivable aging, borrowing base report or certificate or other similar report
provided to Assignee, and Assignor shall provide to Assignee copies of all such
registrations promptly upon the receipt of the same.

                  (e)      Assignor shall undertake all reasonable measures to
cause its employees, agents and independent contractors to assign to Assignor
all rights of authorship to any copyrighted material in which Assignor has or
may subsequently acquire any right or interest.

                  (f)      Performance of this Assignment does not conflict with
or result in a breach of any agreement to which Assignor is bound, except to the
extent that certain intellectual property agreements prohibit the assignment of
the rights thereunder to a third party without the licensor's or other party's
consent and this Assignment constitutes an assignment.

                  (g)      During the term of this Agreement, Assignor will not
transfer or otherwise encumber any interest in the Collateral, except for
non-exclusive licenses granted by Assignor in the ordinary course of business or
as set forth in this Assignment;

                  (h)      Each of the Patents is valid and enforceable, and no
part of the Collateral has been judged invalid or unenforceable, in whole or in
part, and no claim has been made that any part of the Collateral violates the
rights of any third party;

                                      -3-
<Page>

                  (i)      Assignor shall promptly advise Assignee of any
material adverse change in the composition of the Collateral, including but not
limited to any subsequent ownership tight of the Assignor in or to any
Trademark, Patent or Copyright not specified in this Assignment;

                  (j)      Assignor shall (i) protect, defend and maintain the
validity and enforceability of the Trademarks, Patents and Copyrights, (ii) use
its best efforts to detect infringements of the Trademarks, Patents and
Copyrights and promptly advise Assignee in writing of material infringements
detected and (iii) not allow any Trademarks, Patents, or Copyrights to be
abandoned, forfeited or dedicated to the public without the written consent of
Assignee, which shall not be unreasonably withheld unless Assignor determines
that reasonable business practices suggest that abandonment is appropriate.

                  (k)      Assignor shall promptly register the most recent
version of any of Assignor's Copyrights, if not so already registered, and
shall, from time to time, execute and file such other instruments, and take such
further actions as Assignee may reasonably request from time to time to perfect
or continue the perfection of Assignee's interest in the Collateral;

                  (1)      This Assignment creates, and in the case of after
acquired Collateral, this Assignment will create at the time Assignor first has
rights in such after acquired Collateral, in favor of Assignee a valid and
perfected first priority security interest in the Collateral in the United
States securing the payment and performance of the obligations evidenced by the
Loan Agreement upon making the filings referred to in clause (m) below;

                  (m)      To its knowledge, except for, and upon, the filing
with the United States Patent and Trademark office with respect to the Patents
and Trademarks and the Register of Copyrights with respect to the Copyrights
necessary to perfect the security interests and assignment created hereunder and
except as has been already made or obtained, no authorization, approval or other
action by, and no notice to or filing with, any U.S. governmental authority or
U.S. regulatory body is required either (i) for the grant by Assignor of the
security interest granted hereby or for the execution, delivery or performance
of this Assignment by Assignor in the U.S. or (ii) for the perfection in the
United States or the exercise by Assignee of its rights and remedies thereunder;

                  (n)      All information heretofore, herein or hereafter
supplied to Assignee by or on behalf of Assignor with respect to the Collateral
is accurate and complete in all material respects.

                  (o)      Assignor shall not enter into any agreement that
would materially impair or conflict with Assignor's obligations hereunder
without Assignee's prior written consent, which consent shall not be
unreasonably withheld. Assignor shall not permit the inclusion in any material
contract to which it becomes a party of any provisions that could or might in
any way prevent the creation of a security interest in Assignor's rights and
interest in any property included within the definition of the Collateral
acquired under such contracts, except that certain contracts may contain
anti-assignment provisions that could in effect prohibit the creation of a
security interest in such contracts.

                                      -4-
<Page>

                  (p)      Upon any executive officer of Assignor obtaining
actual knowledge thereof, Assignor will promptly notify Assignee in writing of
any event that materially adversely affects the value of any material
Collateral, the ability of Assignor to dispose of any material collateral or the
rights and remedies of Assignee in relation thereto, including the levy of any
legal process against any of the Collateral.

         4.       ASSIGNEE'S RIGHTS. Assignee shall have the right, but not the
obligation, to take, at Assignor's sole expense, any actions that Assignor is
required under this Assignment to take but which Assignor fails to take, after
fifteen (15) days' notice to Assignor. Assignor shall reimburse and indemnify
Assignee for all reasonable costs and reasonable expenses incurred in the
reasonable exercise of its rights under this section 4.

         5.       INSPECTION RIGHTS. Assignor hereby grants to Assignee and its
employees, representatives and agents the right to visit, during reasonable
hours upon prior reasonable written notice to Assignor, and any of Assignor's
plants and facilities that manufacture, install or store products (or that have
done so daring the prior six-month period) that are sold utilizing any of the
Collateral, and to inspect the products and quality control records relating
thereto upon reasonable written notice to Assignor and as often as may be
reasonably requested, but not more than one (1) in every six (6) months;
provided, however, nothing herein shall entitle Assignee access to Assignor's
trade secrets and other proprietary information.

         6.       FURTHER ASSURANCES, ATTORNEY IN FACT.

                  (a)      Upon an Event of Default, on a continuing basis
thereafter, Assignor will, subject to any prior licenses, encumbrances and
restrictions and prospective, licenses, make, execute, acknowledge and deliver,
and file and record in the proper filing and recording places in the United
States, all such instruments, including, appropriate financing and continuation
statements and collateral agreements and filings with the United States Patent
and Trademarks Office and the Register of Copyrights, and take all such action
as may reasonably be deemed necessary or advisable, or as requested by Assignee,
to perfect Assignee's security interest in all Copyrights, Patents and
Trademarks and otherwise to carry out the intent and purposes of this Collateral
Assignment, or for assuming and confirming to Assignee the grant or perfection
of a security interest in all Collateral.

                  (b)      Upon an Event of Default, Assignor hereby irrevocably
appoints Assignee as Assignor's attorney-in-fact, with full authority in the
place and stead of Assignor and in the name of Assignor, Assignee or otherwise,
from time to time in Assignee's discretion, upon Assignor's failure or inability
to do so, to take any action and to execute any instrument which Assignee may

                               MARCAP CORPORATION

             Area Code 312/641-0233 Facsimile Machine: 312/425-2441

                                 EQUIPMENT LEASE

Lease date as of OCTOBER 1, 2000 between MARCAP CORPORATION a Delaware
corporation having its principal office at 20 North Wacker Drive, Suite 2150,
Chicago, Illinois 60606 ("Leassor"), and ORION IMAGING SYSTEMS, INC., a
CORPORATION organized under the laws of the state of DELAWARE and having its
principal office at 9350 TRADE PLACE, SAN DIEGO, CA 92126 ("Lessee").

1.   LEASE. Subject to the terms hereof, Lessor hereby leases to Lessee, and
Lessee hereby leases from Lessor, the equipment ("Equipment") described on
Equipment Schedules ("Schedule or Schedules") to this Lease executed from
time to time by Lessor and Lessee, all of which are made a part hereof. For
the purposes of this Equipment Lease, each Schedule relating to one or more
items of Equipment shall be deemed to incorporate all of the terms and
provisions of this Equipment Lease.

2.   TERMS. The term of Lease for the items of Equipment included on any
Schedule shall commence on the date such items are accepted by Lessee
("Commencement Date") and, subject to the terms hereof, shall continue for
the period of time set forth on said Schedule.

3.   RENTAL. Lessee shall pay to Lessor total rentals for the Equipment
described on each Schedule equal to the product of (i) the periodic rent
payment and (ii) the number of rent payments specified on such Schedule.
Except as otherwise set forth in the Schedule, rent payments shall be due
each month in advance beginning with the Commencement Date. All rent shall be
paid to Lessor at 20 North Wacker Drive, Suite 2720, Chicago, Illinois 60606,
or at such other address as Lessor may specify, without notice or demand and
without abatement, deduction or setoff. Rent and any other payments due
hereunder not made within ten (10) days of the due date shall be subject to a
service charge equal to the lesser of (i) five percent (5%) of the overdue
payment, (ii) the maximum amount permitted by law.

4.   ERRORS IN ESTIMATED COST; OMISSIONS. The rentals set forth on each
Schedule are based upon the estimated costs of Equipment and shall be
adjusted proportionately if the actual cost differs from the estimate. Lessee
authorizes Lessor, with respect to each Schedule, (i) to so adjust the rent
once the actual cost is known, (ii) to insert on such Schedule serial numbers
or other more specific descriptions of the Equipment. "Cost, as used herein,
means the total cost of the Lessor of purchasing and causing delivery and
installation of the Equipment, including taxes, transportation and any other
charges paid by Lessor.

5.   DISCLAIMER OF WARRANTIES. LESSEE ACKNOWLEDGES THAT: (i) THE EQUIPMENT IS
A SIZE, DESIGN, CAPACITY AND MANUFACTURE SELECTED BY LESSEE; (ii) LESSOR IS
NOT A MANUFACTURER NOR A DEALER IN PROPERTY OF SUCH KIND; (iii) NEITHER THE
VENDOR NOR ANY REPRESENTATIVE OF ANY VENDOR OR ANY MANUFACTURER OF THE
EQUIPMENT IS AN AGENT OF LESSOR OR AUTHORIZED TO WAIVE OR ALTER ANY TERM OR
CONDITION OF THIS LEASE; AND (iv) LESSOR HAS NOT MADE AND DOES NOT HEREBY
MAKE ANY WARRANTY, EXPRESS OR IMPLIED, AS TO ANY MATTER WHATSOEVER,
INCLUDING, WITHOUT LIMITATION, THE CONDITION, MERCHANTABILITY OR FITNESS FOR
ANY PARTICULAR PURPOSE OF THE EQUIPMENT. No defect in, unfitness of or an
inability of Lessee to use any Equipment, howsoever caused, shall relieve
Lessee from its obligation to pay rentals or from any other obligations.
Lessor shall not in any event be responsible to Lessee or anyone claiming
through Lessee for any damages, direct, consequential, or otherwise,
resulting from the deliver, installation, use, operation, performance or
condition of any Equipment, or any delay or failure by any vendor in
delivering and/or installing any Equipment or performing any service for
Lessee. Nothing herein shall be construed as depriving Lessee of whatever
rights Lessee may have against any vendor of the Equipment, and Lessor hereby
authorizes Lessee at Lessee's expense, to assert for Lessor's account during
the term of this Lease, all of Lessor's rights under any warranty or promise
given by a vendor and relating to Equipment so long as Lessee is not in
default hereunder. Lessee may communicate with the vendor supplying the
Equipment and receive an accurate and complete statement of those promises
and warranties, including any disclaimers and limitations of them or of
remedies.

6.   ACCEPTANCE. Lessee shall inspect each item of Equipment within 72 hours
after delivery or, where applicable, installation thereof. Unless Lessee
within such period of time gives written notice to Lessor and the vendor
specifying any defect in or other proper objection to an item of Equipment,
it shall be conclusively presumed between Lessor and Lessee that Lessee has
fully inspected such Equipment, that such Equipment is in full compliance
with the terms of this Lease, that such Equipment is in good condition
(operating and otherwise) and repair, and that Lessee has unconditionally
accepted such Equipment. Forthwith after acceptance of each item of
Equipment, Lessee shall execute and deliver to Lessor, Lessor's form of
Delivery and Acceptance Acknowledgment.

                                       1

<Page>

7.   MAINTENANCE. Lessee will maintain the Equipment in good operating order
and appearance, protect the Equipment from deterioration, other than normal
wear and tear, and will not use the Equipment for any purpose other than that
for which it was designed. Lessee will maintain in force a standard
maintenance contract with the manufacturer of the Equipment or a party
authorized by the manufacturer and acceptable to the Lessor to perform such
maintenance (the "maintenance contractor"), and upon request will provide
Lessor with a complete copy of that contract. Lessee's obligation regarding
the maintenance of the Equipment will include, without limitation, all
maintenance and repair recommended or advised either by the manufacturer,
government agencies, or regulatory bodies and those commonly performed by
prudent business and/or professional practice. Upon return of the Equipment,
Lessee will provide a letter from the maintenance contractor certifying that
the Equipment meets all current specifications of the manufacturer, is in
compliance with all pertinent governmental or regulatory rules, laws or
guidelines for its operation or use, is qualified for the maintenance
contractor's standard maintenance contract and is at then current release,
revision and engineering change levels. Lessee agrees to pay any costs
necessary for the manufacturer to bring the Equipment to then current
release, revision and engineering change levels, and to re-certify the
Equipment as eligible for such maintenance contract at the expiration of the
lease term. The lease term will continue upon the same terms and conditions
until recertification has been obtained.

8.   SECURITY DEPOSIT. The security deposit, if any, specified on each
Schedule shall secure the full and faithful performance of all agreements,
obligations and warranties of Lessee hereunder, including, but not limited
to, the agreement of Lessee to return the Equipment upon the expiration or
earlier termination of this Lease in the condition specified. Such deposit
shall not excuse the performance of any such agreements, obligations or
warranties of Lessee or prevent a default. Lessor may (but need not) apply
all or any part of such security deposit toward discharge of any overdue
obligation of Lessee. To the extent any portion of the security deposit is so
applied by Lessor, Lessee shall forthwith restore the security deposit to its
full amount. If upon the expiration of the term of this Lease, Lessee shall
have fully complied with all of its agreements, obligations and warranties
hereunder, any unused portion of such security deposit will be refunded to
Lessee. Lessor shall not be obligated to pay interest on the security deposit.

9.   INSURANCE. Lessee, at its expense, shall keep the Equipment insured
against all risk of loss or physical damage (including comprehensive boiler
and machinery coverage and earthquake and flood insurance if Lessor
determines that such events could occur in the area where the Equipment is
located) for the full replacement value of the Equipment. Lessee shall
further provide and maintain comprehensive public liability insurance against
claims for bodily injury, death and/or property damage arising out of the
use, ownership, possession, operation or condition of the Equipment, together
with such other insurance as may be required by law or reasonably requested
by Lessor. All said insurance shall name both Lessor and Lessee as parties
insured and shall be in form and amount and with insurers satisfaction to
Lessor, and Lessee shall furnish to Lessor certified copies or certificates
of the policies of such insurance and each renewal thereof. Each insurer must
agree, by endorsement upon the policy or policies issued by it, that it will
give Lessor not less than 30 days written notice before such policy or
policies are canceled or altered, and, under the physical damage insurance,
(a) that losses shall be payable solely to Lessor, and (b) that no act or
omission of Lessee or any of its officers, agents, employees or
representatives shall affect the obligation of the insurer to pay the full
amount of any loss. Lessee hereby irrevocably authorizes Lessor to make,
settle and adjust claims under such policy or policies of physical damage
insurance and to endorse the name of Lessee on any check or other item of
payment for the proceeds thereof; it being understood, however, that unless
otherwise directed in writing by Lessor, Lessee shall make and file timely
all claims under such policy or policies, and unless Lessee is then in
default, Lessee may, with the prior written approval of Lessor (which will
not be unreasonably withheld) settle and adjust all such claims.

10.  RISK OF LOSS. As used herein, the term "Event of Loss" shall mean any of
the following events with respect to any item of the Equipment: (a) the
actual or constructive total loss of such Equipment; (b) the loss, theft, or
destruction of such Equipment or damage to such Equipment to such extent as
shall make repair thereof uneconomical or shall render such Equipment
permanently unfit for normal use for any reason whatsoever; or (c) the
condemnation, confiscation, requisition, seizure, forfeiture or other taking
of title to or use of such Equipment. Except as expressly hereinafter
provided, the occurrence of any Event of Loss or other damage to or
deprivation of use of any Equipment, howsoever occasioned, shall not reduce
or impair any obligation of Lessee hereunder, and, without limiting the
foregoing, shall not result in any abatement or reduction in rentals
whatsoever. Lessee hereby assumes and shall bear, from the time such risk
passes to Lessor from the vendor until expiration or termination of the lease
term and return of the Equipment to Lessor, the entire risk of any Event of
Loss or any other damage to or deprivation of use of the Equipment, howsoever
occasioned.

Upon the occurrence of any damage to any Equipment not constituting an Event of
Loss, Lessee, at its sole cost and expense, shall promptly repair and restore
such Equipment so as to return such Equipment to substantially the same
condition as existed prior to the date of such occurrence (assuming such
Equipment was then in the condition required by this Lease). Provided that
Lessee is not then in default hereunder, upon receipt of evidence reasonably
satisfactory to Lessor of completion of such repairs and restoration in
accordance with the terms of this Lease, Lessor will apply any insurance
proceeds received by Lessor on account of such occurrence to the cost of such
repairs and restoration; it being understood, however, that if at such time
Lessee shall be in default hereunder, Lessor may, at its option, retain any part
or all of such proceeds and apply same to any obligations of Lessee to Lessor.

Upon the occurrence of an Event of Loss, Lessee shall immediately notify Lessor
in writing of such occurrence, fully informing Lessor of all details with
respect thereto, and, on or before the first to occur of (i) 30 days after the
date upon which such Event of Loss occurs, or (ii) 5 days after the date on
which either Lessor shall receive any proceeds of insurance in respect of such
Event of Loss or any underwriter of insurance on the Equipment shall advise
Lessor or Lessee in writing that it disclaims liability in respect of such Event
of Loss, if such be the case, Lessee shall pay to Lessor an amount equal to the
sum of (a) accrued but unpaid rent and other sums due under the Lease plus (b)
the present value of all future rentals reserved in the Lease and contracted to
be paid over the unexpired term discounted at 6% per annum plus (c) the present
value of Lessor's residual value of the Equipment as of the expiration of the
term discounted at 6% per annum (the "Stipulated Loss Value"), less the amount
of any insurance proceeds or condemnation or similar award by a governmental
authority then actually received by Lessor on account of such Event of Loss. No
delay or refusal by any insurance company or governmental authority in making
payment on account of such Event of Loss shall extend or otherwise affect the
obligations of Lessee hereunder. Lessee shall continue to pay all rentals and
other sums due hereunder up to and including the date upon which the Stipulated
Loss Value is actually received in full by Lessor, whereupon this Lease with
respect to such Equipment shall terminate and all rentals reserved hereunder
with respect to such Equipment from the date such payment is received in full by
Lessor, as aforesaid, to what would have been the end of the term hereof, shall
abate. No such payment shall affect Lessee's obligations with

                                       2

<Page>

respect to Equipment not subject to an Event of Loss. After receipt by Lessor
of all sums due hereunder, Lessor will upon request of Lessee transfer its
interest, if any, in such Equipment to Lessee on an "as is, where is" basis
and without warranty by or recourse to Lessor.

The proceeds of insurance in respect of an Event of Loss and any award on
account of any condemnation or other taking of any Equipment by a governmental
authority shall be paid to Lessor and applied by Lessor against the obligation
of Lessee to pay Lessor the Stipulated Loss Value of such Equipment (or, if
Lessee shall have first paid the Stipulated Loss Value in full, shall be
promptly paid over by Lessor to Lessee up to the extent necessary to reimburse
Lessee for payment of the Stipulated Loss Value); and the balance, if any, of
such proceeds or award shall be paid over promptly by Lessor to Lessee if Lessee
is not then in default hereunder. If Lessee is in default hereunder, Lessor may
at its option apply all or any part of such proceeds to any obligations of
Lessee to Lessor.

11.  INDEMNITY. Lessee shall indemnify and hold Lessor harmless from and
against any and all claims, costs, expenses (including attorneys' fees)
losses and liabilities of whatsoever nature arising out of or occasioned by
or in connection with (i) the purchase, delivery, installation, acceptance,
rejection, ownership, leasing, possession, use, operation, condition or
return of any Equipment including, without limitation, any claim alleging
latent or other defects and any claim arising out of strict liability in
tort, or (ii) any breach by Lessee of any of its obligations hereunder.

12.  TAXES. Lessee shall pay as and when due, and indemnify and hold Lessor
harmless from and against, all present and future taxes and other
governmental charges (including, without limitation, sales, use, leasing,
stamp and personal property taxes and license and registration fees), and
amounts in lieu of such taxes and charges and any penalties and interest on
any of the foregoing, imposed, levied or based upon, in connection with or as
a result of the purchase, ownership, delivery, leasing, possession or use of
the Equipment or the exercise by Lessee of any option hereunder, or based
upon or measured by rentals or receipts with respect to this Lease. Lessee
shall not, however, be obligated to pay any taxes on or measured by Lessor's
net income. Lessee authorizes Lessor to add to the amount of each rental
installment any sales or leasing tax that may be imposed on or measured by
such rental installment. Notwithstanding the foregoing, unless and until
Lessor notifies Lessee in writing to the contrary, Lessor will file all
personal property tax returns covering the Equipment and will pay the
personal property taxes levied or assessed thereon. Lessee, upon receipt of
invoice, will promptly pay to Lessor, as additional rent, an amount equal to
the lessor of (i) property taxes so paid by Lessor plus the cost incurred by
Lessor if Lessor elects to contest such tax, or (ii) the original property
tax assessment.

If not thereby subjecting the Equipment to forfeiture or sale, Lessee may at its
expense contest in good faith, by appropriate proceedings, the validity and/or
amount of any of the taxes or other governmental charges described above,
provided that prior written notice of any such contest shall be given to Lessor
together with security satisfactory to Lessor for the payment of the amount
being contested and provided further that Lessor has not contested such tax.

13.  NOTICE; INSPECTION. Lessee shall give Lessor immediate notice of any
attachment, judicial process, lien, encumbrance or claim affecting the
Equipment, any loss or damage to the Equipment or material accident or
casualty arising out of the use, operation or condition of the Equipment, and
any change in the residency or principal place of business of Lessee or any
guarantor of Lessee's obligations hereunder ("Guarantor"). Lessor may, (but
need not), for the purpose of inspection, at all reasonable business hours,
enter from time to time upon any premises where the Equipment is located.

14.  ALTERATIONS. Lessee shall not make or permit any changes or alterations
to the Equipment without Lessor's prior written consent. All accessories,
replacements, parts and substitutions for or which are added or attached to
the Equipment shall become the property of Lessor, included in the definition
of Equipment, and subject to this Lease.

15.  TITLE. Lessee shall keep the Equipment free from all liens and
encumbrances. Lessee shall execute and/or furnish to Lessor any further
instruments and assurances reasonably requested from time to time by Lessor
to protect its interest, and shall otherwise cooperate to defend the title of
Lessor and to maintain the status of the Equipment as personal property,
including, without limitation, the execution of financing statements and the
furnishing of waivers with respect to rights in the Equipment from the owners
and mortgagees of the real estate on which the Equipment is or will be
located. Lessor may file or record any such financing statements, waivers or
with instruments in order to protect its interest. Lessee hereby irrevocably
authorizes Lessor to sign on behalf of Lessee and file in the appropriate
public office (s) UCC financing statements covering the Equipment and all
proceeds thereof.

16.  QUIET ENJOYMENT. So long as Lessee shall not be in default and fully
performs all of its obligations hereunder, Lessor will not interfere with the
quiet use and enjoyment of the Equipment by Lessee.

17.  RETURN. Upon the expiration or earlier termination of this Lease with
respect to any Equipment, Lessee, pursuant to Lessor's instructions and at
Lessee's expense, will have the Equipment deinstalled, audited by the
maintenance contractor or another party acceptable to Lessor, packed and
shipped fully insured and in accordance with the manufacturer's instructions
to the destination specified by Lessor; provided, however, that Lessor shall
reimburse Lessee for any freight charges incurred at the direction of Lessor
which may exceed the charges for shipment from the location of such Equipment
to Lessor's place of business in Chicago, Illinois. All returned Equipment
shall be in good operating order and appearance, other than normal wear and
tear and shall comply with all of the requirements of Section 7. Lessee shall
pay Lessor, on demand, the cost of any repairs normal wear and tear and shall
comply with all of the requirements of Section 7. Lessee shall pay to Lessor,
on demand, the cost of any repairs necessary to place the Equipment in the
condition required by this Lease.

18.  LESSEE'S WARRANTIES. In order to induce Lessor to enter into this Lease
and to lease the Equipment to Lessee hereunder, Lessee represents and
warrants that: (a) Disclosures. (i) its applications, financial statements
and reports which have been submitted by it to Lessor are, and all
information hereafter furnished by Lessee to Lessor will be, true and correct
in all material respects as of the date submitted; (ii) as of the date
hereof, the date of any Schedule and any lease Commencement Date, there has
been no material adverse change in any matter stated in such applications,
financial statements and reports; (iii) there are no known contingent
liabilities or liabilities for taxes of Lessee which are not

                                       3

<Page>

reflected in said financial statements or reports; and, (iv) none of the
foregoing omit or omitted to state any material fact. (b) Organization.
Lessee is an organizational entity described on the signature page hereof and
is duly organized, validly existing and in good standing in the state first
set forth above and duly qualified to do business in each state in which the
Equipment will be located. (c) Power and Authority. Lessee has full power,
authority and legal right to execute, deliver and perform this Lease and any
Schedule thereto, and the execution, delivery and performance hereof has been
duly authorized by all necessary action of Lessee. (d) Enforceability. This
Lease and any Schedule or other document executed in connection therewith has
been duly executed and delivered by Lessee and constitutes a legal, valid and
binding obligation of Lessee enforceable in accordance with its terms. (e)
Consents and Permits. The execution, delivery and performance of this Lease
does not require any approval or consent of any stockholders, partners or
proprietors or of any trustee or holders of any indebtedness or obligations
of Lessee, and will not contravene any law, regulation, judgment or decree
applicable to Lessee, or the certificate of organization, partnership
agreement or by-laws of Lessee, or contravene the provisions of, or
constitute a default under, or result in the creation of any lien upon any
property of Lessee under any mortgage, instrument or other agreement to which
Lessee is a party or by which Lessee or its assets may be bound or affected.
No authorization, approval, license, filing or registration with any court or
governmental agency or instrumentality except as disclosed is necessary in
connection with the execution, delivery, performance, validity and
enforceability of this Lease. (f) Title to Equipment. On each Commencement
Date, Lessor shall have good and marketable title to the items of Equipment
being subjected to this Lease on such date, free and clear of all liens
created by or through Lessee.

19.  ASSIGNMENT. Lessee hereby consents to any assignment by Lessor and any
reassignment of this Lease or rents hereunder with or without notice. Lessee
agrees that the rights of any assignee shall not be subject to any defense,
setoff or counterclaim that Lessee may have against Lessor, and that any such
assignee shall have all of Lessor's rights hereunder, but none of Lessor's
obligations. Neither this Lease nor any of Lessee's rights hereunder shall be
assignable by Lessee, either by its own act or by operation of law, without
the prior written consent of Lessor, and any such attempted assignment shall
be void. Lessee further agrees it will not, without the prior written consent
of Lessor, allow the Equipment to be used by persons other than employees of
Lessee, or rent or sublet any Equipment to others or relocate any Equipment
from the premises where originally installed.

20.  LESSOR'S RIGHT TO TERMINATE. Without limiting the rights of Lessor in
the event of a default by Lessee, Lessor shall at any time prior to
acceptance of any Equipment have the right to terminate this Lease with
respect to such Equipment if (a) there shall be an adverse change in Lessee's
or any Guarantor's financial position or credit standing, or (b) Lessor
otherwise in good faith deems itself insecure, or (c) such Equipment is not
for any reason delivered to Lessee within 90 days or accepted by Lessee
within 30 days after any estimated delivery date thereof specified in the
Schedule describing such Equipment, or (d) Lessee rejects any Equipment in
accordance with Paragraph 6 hereof. Upon any termination by Lessor pursuant
to this Paragraph, Lessee shall forthwith reimburse to Lessor all sums paid
by Lessor with respect to such Equipment and pay to Lessor all other sums
then due hereunder; whereupon, if Lessee is not then in default and has then
fully performed all of its obligations hereunder, Lessor will, upon request
of Lessee, transfer to Lessee without warranty or recourse any rights that
Lessor may then have with respect to such Equipment.

21.  RIGHT TO PERFORM OBLIGATIONS. If Lessee shall fail to make any payment
or perform any act or obligation required of Lessee hereunder, Lessor may
(but need not) at any time thereafter make such payment or perform such act
or obligation at the expense of Lessee. Any expense so incurred by Lessor
shall constitute additional rental hereunder payable by Lessee to Lessor upon
demand with interest at the overdue rate, as hereinafter defined.

22.  EVENTS OF DEFAULT. An event of default shall occur hereunder if the
owner(s) of Lessee sell or otherwise transfer their controlling interest in
Lessee or if Lessee (i) fails to pay any installment of rent or other payment
required hereunder when due and such failure shall continue for more than
five (5) days; or (ii) attempts to or does remove from the premises, sell,
transfer, encumber, part with possession of, or sublet any item of Equipment;
or (iii) breaches or shall have breached any representation or warranty made
or given by Lessee or Guarantor in this Lease or in any other document
furnished to Lessor in connection herewith, or any such representation or
warranty shall be untrue or, by reason of failure to state a material fact or
otherwise, shall be misleading; or (iv) fails to perform or observe any other
covenant, condition or agreement to be performed or observed by it hereunder,
and such failure or breach shall continue unremedied for a period of thirty
(30) days after the earlier of (a) the date on which Lessee obtains, or
should have obtained knowledge of such failure or breach; or (b) the date on
which notice thereof shall be given by Lessor to Lessee; or (v) shall become
insolvent or bankrupt or make an assignment for the benefit of creditors or
consent to the appointment of a trustee or receiver, or a trustee or receiver
shall be appointed for a substantial part of its property without its
consent, or bankruptcy or reorganization or insolvency proceeding shall be
instituted by or against Lessee; or (vi) ceases doing business as a going
concern.

23.  REMEDIES UPON DEFAULT. In the event of any default by Lessee, Lessor
may, at its option, do one or more of the following: (a) terminate this Lease
and Lessee's rights hereunder; (b) proceed by appropriate court action to
enforce performance of the terms of this Lease and/or recover damages for the
breach hereof; (c) directly or by its agent, and without notice or liability
or legal process, enter upon any promises where any Equipment may be located,
take possession of such Equipment, and either store it on said premises
without charge or remove the same (any damages occasioned by such taking of
possession, storage or removal being waived by Lessee); and/or (d) declare as
immediately due and payable and forthwith recover from Lessee, as liquidated
damages and not as a penalty, an amount equal to the then aggregate
Stipulated Loss Value of the Equipment.

In the event of any repossession of any Equipment by Lessor, Lessor may (but
need not), without notice to Lessee, (A) hold or use all or part of such
Equipment for any purpose whatsoever, (B) sell all or part of such Equipment at
public or private sale for cash or on credit and/or (C) relet all or part of
such Equipment upon such terms as Lessor may solely determine; in each case
without any duty to account to Lessee except as herein expressly provided. After
any repossession of Equipment by Lessor there shall be applied on account of the
obligations of Lessee hereunder one of the following chosen at the option of
Lessor: (x) the net proceeds actually received by Lessor from a sale of such
Equipment, after deduction of all expenses of sale and other expenses
recoverable by Lessor hereunder, or (y) the then "net fair market value" of such
Equipment, as determined by an appraisal made by an independent appraiser
selected by Lessor at Lessee's expense, taking into account a reasonable
estimate of all expenses necessary to effect a sale and the other expenses
recoverable by Lessor hereunder; and Lessee shall remain liable, subject to all
provisions of this Lease, for the balance of the Stipulated Loss Value. No
termination, repossession or other act by Lessor

                                       4

<Page>

after default shall relieve Lessee from any of its obligations hereunder. In
addition to all other charges hereunder, Lessee shall pay to Lessor on demand
all fees, costs and expenses incurred by Lessor as a result of such default,
including without limitation, reasonable attorneys', appraisers' and brokers'
fees and expenses and costs of removal, storage, transportation, insurance
and disposition of the Equipment (except to the extent deducted from "net
fair market value" or net proceeds of sale, as aforesaid). In the event that
any court of competent jurisdiction determines that any provision of this
Paragraph 23 is invalid or unenforceable in whole or in part, such
determination shall not prohibit Lessor from establishing its damages
sustained as a result of any breach of this Lease in any action or proceeding
in which Lessor seeks to recover such damages. The remedies provided herein
in favor of Lessor shall not be exclusive, but shall be cumulative and in
addition to all other remedies existing at law or in equity, any one or more
of which may be exercised simultaneously or successively.

24.  NON-WAIVER. Lessor's failure at any time to require strict performance
by Lessee of any provision hereof shall not waive or diminish Lessor's rights
thereafter to demand strict performance thereof or of any other provision.
None of the provisions of this Lease shall be held to have been waived by any
act or knowledge of Lessor, but only by a written instrument executed by
Lessor and delivered to Lessee. Waiver of any default shall not be a waiver
of any other or subsequent default,

25.  COMMUNICATIONS. Any notice or other communication required or desired to
be given hereunder shall be given in writing and shall be deemed to have been
duly given and received when sent by confirmed express mail, when delivered
by hand or by confirmed Federal Express delivery or other reputable overnight
courier or by facsimile on the date actually received by the addressee and,
when deposited in the United States mail, registered or certified, postage
prepaid, return receipt requested, on the third business day succeeding the
day on which such notice was mailed, addressed to the respective addresses of
the parties set forth at the beginning of this Lease or any other address
designated by notice served in accordance herewith.

26.  FINANCIAL AND OTHER INFORMATION. Lessee shall furnish to Lessor such
financial and other information about the condition and affairs of Lessee and
any Guarantor and about the Equipment as Lessor may from time to time
reasonably request.

27.  HOLDING OVER. Any use of the Equipment beyond the initial lease term or
any renewal thereof shall be deemed to be an extension of the Lease term on a
month-to-month basis terminable by Lessor on ten (10) days notice to Lessee
and all obligations of Lessee herein, including payment of rent shall
continue during such holding over.

28.  SURVIVAL. Lessee's indemnities shall survive the expiration or other
termination of this Lease.

29.  SERVICE OF PROCESS; VENUE. IN ORDER TO INDUCE LESSOR TO EXECUTE THIS
LEASE, LESSEE HEREBY AGREES THAT ALL ACTIONS OR PROCEEDINGS ARISING DIRECTLY
OR INDIRECTLY FROM THIS LEASE SHALL BE LITIGATED ONLY IN COURTS (STATE OR
FEDERAL) HAVING SITUS IN THE STATE OF ILLINOIS AND THE COUNTY OF COOK UNLESS
LESSOR, IN ITS SOLE DISCRETION, WAIVES THIS PROVISION. LESSEE HEREBY
EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION
OR PROCEEDING COMMENCED BY LESSOR IN ANY STATE OR FEDERAL COURT LOCATED
WITHIN THE STATE OF ILLINOIS, HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS
AND COMPLAINT OR OTHER PROCESS OR PAPERS ISSUED THEREIN, AND AGREES THAT
SERVICE MAY BE MADE BY REGISTERED OR CERTIFIED MAIL ADDRESSED TO LESSEE AS
PROVIDED FOR IN PARAGRAPH 25 HEREOF, AND THAT SERVICE SO MADE SHALL BE DEEMED
TO BE COMPLETED ON THE THIRD BUSINESS DAY AFTER THE SAME SHALL HAVE BEEN
MAILED IN THIS MANNER. LESSEE WAIVES ANY CLAIM THAT ANY ACTION INSTITUTED BY
LESSOR HEREUNDER IS IN AN INCONVENIENT FORUM OR AN IMPROPER FORUM BASED ON
LACK OF VENUE. TO THE EXTENT PERMITTED BY LAW, LESSEE HEREBY WAIVES TRIAL BY
JURY AND ANY RIGHT OF SETOFF OR COUNTERCLAIM IN ANY ACTION BETWEEN LESSOR AND
LESSEE.

30.  SECURITY INTEREST. To the extent that any of the transactions evidenced
by Schedules are secured transactions, Lessee hereby grants to Lessor a
security interest in the Equipment described on such Schedules as security
for all Lessee's obligations and liabilities under the Lease and Lessee
authorizes Lessor to disburse the purchase price of such Equipment directly
to the vendor(s) thereof.

31.  NON-CANCELABLE LEASE; UNCONDITIONAL OBLIGATIONS. THIS LEASE CANNOT BE
CANCELED OR TERMINATED EXCEPT BY LESSOR AS EXPRESSLY PROVIDED FOR HEREIN.
LESSEE AGREES THAT LESSEE'S OBLIGATION TO PAY ALL RENT AND PAY AND PERFORM
ALL OTHER OBLIGATIONS HEREUNDER SHALL BE ABSOLUTE, IRREVOCABLE, UNCONDITIONAL
AND INDEPENDENT AND SHALL BE PAID OR PERFORMED WITHOUT ABATEMENT, DEDUCTION
OR OFFSET OF ANY KIND WHATSOEVER.

32.  LESSEE WAIVERS. To the extent permitted by applicable law, Lessee hereby
waives any and all rights and remedies conferred upon a Lessee by Sections
2A-508 through 2A-522 of the Uniform Commercial Code, including, without
limitations, the right to (i) cancel this Lease; (ii) repudiate this Lease;
(iii) reject this Lease; (iv) revoke acceptance of the Equipment; (v) recover
damages from Lessor for any breach of warranty or any other reason; (vi)
claim a security interest in any rejected property in Lessee's possession;
(vii) deduct all or any part of claimed damages resulting from Lessor's
default; (viii) accept partial delivery of the Equipment; (ix) "cover" by
making any purchase or lease of equipment in substitution of the Equipment;
(x) recover any general, special, incidental or consequential damages from
Lessor for any reason.

33.  MISCELLANEOUS. Interest on any past due sums shall accrue at the rate of
1 1/2% per month, not to exceed the maximum rate permitted by law (the
"overdue rate"). If any provision of this Lease or the application thereof is
hereafter held invalid or unenforceable, the remainder of this Lease shall
not be affected thereby, and to this end the provisions of this Lease are
declared severable. Titles to Paragraphs shall not be considered in the
interpretation of this Lease. This Lease (including the Schedules and any
Riders hereto) sets forth the entire understanding

                                       5

<Page>

between the parties and may not be modified except in a writing signed by both
parties. Except as may be expressly provided in any Schedule or Rider hereto, no
options to purchase any of the Equipment or extend the term of this Lease with
respect to any Equipment have been granted or agreed to by Lessor, and none
shall be implied by this Lease. If there is more than one Lessee, the
obligations of Lessee hereunder are joint and several. The necessary grammatical
changes required to make the provisions hereof apply to corporations,
partnerships and/or individuals, men or women, shall in all cases be assumed as
though in each case fully expressed. Subject to the terms hereof, this Lease
shall be binding upon and inure to the benefit of Lessor and Lessee and their
respective personal representatives, successors and assigns. This Lease shall be
governed in all respects by the laws of the State of Illinois. This Lease is
submitted to Lessor for its acceptance or rejection and will not become
effective until accepted by Lessor in writing at its office in Chicago,
Illinois. The individuals executing this Lease on behalf of Lessee personally
warrant that they are doing so pursuant to due authorization and that by so
executing this Lease, Lessee is being bound hereby.

Dated as of the day and year first above written.
