                                CREDIT AGREEMENT

      This Credit Agreement, dated as of January 16, 2002 (this "Agreement"), is
made and entered into between BANK OF AMERICA, N.A. with an office at 55 South
Lake, Suite 900, Pasadena, California 91001 (the "Lender"), and SPACELABS
MEDICAL, INC., a Delaware corporation ("Spacelabs Delaware"), SPACELABS MEDICAL,
INC., a California corporation ("Spacelabs California"), SPACELABS BURDICK,
INC., a Delaware corporation ("Spacelabs Burdick"), VITA-STAT MEDICAL SERVICES,
INC., a Florida corporation, LIFECLINIC MEDICAL DATA CORPORATION, a Washington
corporation, and LIFECLINIC.COM CORPORATION, a Washington corporation, with an
office for notice purposes at the address set forth in Section 12.8
(collectively, the "Borrowers").

                              W I T N E S S E T H:

      WHEREAS, the Borrowers have requested that the Lender make available to
the Borrowers a revolving line of credit for loans and letters of credit in an
amount not to exceed $20,000,000, which extensions of credit the Borrowers will
use for the purposes permitted hereunder;

      WHEREAS, capitalized terms used in this Agreement and not otherwise
defined herein shall have the meanings ascribed thereto in Annex A which is
attached hereto and incorporated herein; the rules of construction contained
therein shall govern the interpretation of this Agreement, and all Annexes,
Exhibits and Schedules attached hereto are incorporated herein by reference;

      WHEREAS, the Lender has agreed to make available to the Borrowers a
revolving credit facility upon the terms and conditions set forth in this
Agreement.

      NOW, THEREFORE, in consideration of the mutual conditions and agreements
set forth in this Agreement, and for good and valuable consideration, the
receipt of which is hereby acknowledged, the Lender and the Borrowers hereby
agree as follows.

                                    ARTICLE 1
                           LOANS AND LETTERS OF CREDIT

      1.1 Total Facility. Subject to all of the terms and conditions of this
Agreement, the Lender agrees to make available a total credit facility of up to
$20,000,000 (the "Total Facility") to the Borrowers from time to time during the
term of this Agreement. The Total Facility shall be composed of a revolving line
of credit consisting of Revolving Loans and Letters of Credit described herein.

      1.2 Revolving Loans.

            (a) Amounts. Subject to the satisfaction of the conditions precedent
set forth in Article 8, the Lender agrees, upon the Borrowers' request from time
to time on any Business Day during the period from the Closing Date to the
Termination Date, to make revolving loans (the "Revolving Loans") to the
Borrowers in amounts not to exceed Availability. The Lender, however, in its
discretion, may elect to make Revolving Loans or issue or arrange to have issued
Letters of Credit in excess of the Borrowing Base on one or more occasions, but
if it does so, the Lender shall not be deemed thereby to have changed the limits
of the Borrowing Base or to be obligated to exceed such limits on any other
occasion. If any Borrowing would exceed Availability, the Lender may refuse to
make or may otherwise restrict the making of Revolving Loans as the Lender
determines until such excess has been eliminated.

            (b) Procedure for Borrowing.

                  (1) Each Borrowing shall be made upon the Borrowers'
            irrevocable written notice delivered to the Lender in the form of a
            notice of borrowing ("Notice of Borrowing"), which must be received
            by the Lender prior to (i) 12:00 noon (Los Angeles time) three
            Business Days prior to the requested Funding Date, in the case of
            LIBOR Revolving Loans and (ii) 11:00 a.m. (Los Angeles time) on the
            requested Funding Date, in the case of Base Rate Revolving Loans,
            specifying:

                      (A) the amount of the Borrowing, which in the case of a
                  LIBOR Revolving Loan must equal or exceed $1,000,000 (and
                  increments of $500,000 in excess of such amount);

                      (B) the requested Funding Date, which must be a Business
                  Day;

                      (C) whether the Revolving Loans requested are to be Base
                  Rate Revolving Loans or LIBOR Revolving Loans (and if not
                  specified, it shall be deemed a request for a Base Rate
                  Revolving Loan); and

                      (D) the duration of the Interest Period for LIBOR
                  Revolving Loans (and if not specified, it shall be deemed a
                  request for an Interest Period of one month);

            provided, however, that with respect to the Borrowing to be made on
            the Closing Date, such Borrowings will consist of Base Rate
            Revolving Loans only.

                  (2) In lieu of delivering a Notice of Borrowing, the Borrowers
            may give the Lender telephonic notice of such request for Revolving
            Loans to the Designated Account on or before the deadline set forth
            above. The Lender at all times shall be entitled to rely on such
            telephonic notice in making such Revolving Loans, regardless of
            whether any written confirmation is received.

                  (3) The Borrowers shall have no right to request a Loan while
            a Default or an Event of Default has occurred and is continuing.

            (c) Reliance upon Authority. Prior to the Closing Date, the
Borrowers shall deliver to the Lender a notice setting forth the account of the
Borrowers ("Designated Account") to which the Lender is authorized to transfer
the proceeds of the Revolving Loans requested hereunder. The Borrowers may
designate a replacement account from time to time by written notice. All such
Designated Accounts must be reasonably satisfactory to the Lender. The Lender is
entitled to rely conclusively on any person's request for Revolving Loans on
behalf of the Borrowers, so long as the proceeds thereof are to be transferred
to the Designated Account. The Lender has no duty to verify the identity of any
individual representing himself or herself as a person authorized by the
Borrowers to make such requests on its behalf.

            (d) No Liability. The Lender shall not incur any liability to the
Borrowers as a result of acting upon any notice referred to in Sections 1.2(b)
and (c), which the Lender believes in good faith to have been given by an
officer or other person duly authorized by the Borrowers to request Revolving
Loans on its behalf. The crediting of Revolving Loans to the Designated Account
conclusively establishes the obligation of the Borrowers to repay such Revolving
Loans as provided herein.

            (e) Notice Irrevocable. Any Notice of Borrowing (or telephonic
notice in lieu thereof) made pursuant to Section 1.2(b) shall be irrevocable.
The Borrowers shall be bound to borrow the funds requested therein in accordance
therewith.

            (f) Making of Revolving Loans. Promptly after receipt of a Notice of
Borrowing or telephonic notice in lieu thereof, the Lender shall make the
proceeds of such Revolving Loans available to the Borrowers on the applicable
Funding Date by transferring same day funds to the Designated Account; provided,
however, that subject to Section 1.2(a) the amount of Revolving Loans so made on
any date shall not exceed the Availability on such date.

      1.3 Letters of Credit.

            (a) Agreement to Issue or Cause To Issue. Subject to the terms and
conditions of this Agreement, the Lender agrees (i) to cause the Letter of
Credit Issuer to issue for the account of the Borrowers one or more
commercial/documentary and standby letters of credit ("Letter of Credit") and/or
(ii) to provide credit support or other enhancement to a Letter of Credit Issuer
acceptable to Lender, which issues a Letter of Credit for the account of the
Borrowers (any such credit support or enhancement being herein referred to as a
"Credit Support") from time to time during the term of this Agreement.

            (b) Amounts; Outside Expiration Date. The Lender shall not have any
obligation to issue or cause to be issued any Letter of Credit or to provide
Credit Support for any Letter of Credit at any time if: (i) the maximum face
amount of the requested Letter of Credit is greater than the Unused Letter of
Credit Subfacility at such time; (ii) the maximum undrawn amount of the
requested Letter of Credit and all commissions, fees, and charges due from the
Borrowers in connection with the opening thereof would exceed Availability at
such time; or (iii) such Letter of Credit has an expiration date less than 30
days prior to the Stated Termination Date or more than 12 months from the date
of issuance for standby letters of credit and 180 days for documentary letters
of credit.

            (c) Other Conditions. In addition to the conditions precedent
contained in Article 8, the obligation of the Lender to issue or to cause to be
issued any Letter of Credit or to provide Credit Support for any Letter of
Credit is subject to the following conditions precedent having been satisfied in
a manner reasonably satisfactory to the Lender:

                  (1) The Borrowers shall have delivered to the Letter of Credit
            Issuer, at such times and in such manner as such Letter of Credit
            Issuer may prescribe, an application in form and substance
            satisfactory to such Letter of Credit Issuer and reasonably
            satisfactory to the Lender for the issuance of the Letter of Credit
            and such other documents as may be required pursuant to the terms
            thereof, and the form, terms and purpose of the proposed Letter of
            Credit shall be reasonably satisfactory to the Lender and the Letter
            of Credit Issuer; and

                  (2) As of the date of issuance, no order of any court,
            arbitrator or Governmental Authority shall purport by its terms to
            enjoin or restrain money center banks generally from issuing letters
            of credit of the type and in the amount of the proposed Letter of
            Credit, and no law, rule or regulation applicable to money center
            banks generally and no request or directive (whether or not having
            the force of law) from any Governmental Authority with jurisdiction
            over money center banks generally shall prohibit, or request that
            the proposed Letter of Credit Issuer refrain from, the issuance of
            letters of credit generally or the issuance of such Letters of
            Credit.

<PAGE>

            (d) Issuance of Letters of Credit.

                  (1) Request for Issuance. The Borrowers must notify the Lender
            of a requested Letter of Credit at least three (3) Business Days
            prior to the proposed issuance date. Such notice shall be
            irrevocable and must specify the original face amount of the Letter
            of Credit requested, the Business Day of issuance of such requested
            Letter of Credit, whether such Letter of Credit may be drawn in a
            single or in partial draws, the Business Day on which the requested
            Letter of Credit is to expire, the purpose for which such Letter of
            Credit is to be issued, and the beneficiary of the requested Letter
            of Credit. The Borrowers shall attach to such notice the proposed
            form of the Letter of Credit.

                  (2) Responsibilities of the Lender; Issuance. As of the
            Business Day immediately preceding the requested issuance date of
            the Letter of Credit, the Lender shall determine the amount of the
            applicable Unused Letter of Credit Subfacility and Availability. If
            (i) the face amount of the requested Letter of Credit is less than
            the Unused Letter of Credit Subfacility and (ii) the amount of such
            requested Letter of Credit and all commissions, fees, and charges
            due from the Borrowers in connection with the opening thereof would
            not exceed Availability, the Lender shall cause the Letter of Credit
            Issuer to issue the requested Letter of Credit on the requested
            issuance date so long as the other conditions hereof are met.

                  (3) No Extensions or Amendment. The Lender shall not be
            obligated to cause the Letter of Credit Issuer to extend or amend
            any Letter of Credit issued pursuant hereto unless the requirements
            of this Section 1.3 are met as though a new Letter of Credit were
            being requested and issued.

            (e) Payments Pursuant to Letters of Credit. The Borrowers agree to
reimburse immediately the Letter of Credit Issuer for any draw under any Letter
of Credit and the Lender upon any payment pursuant to any Credit Support, and to
pay the Letter of Credit Issuer the amount of all other charges and fees payable
to the Letter of Credit Issuer in connection with any Letter of Credit
immediately when due, irrespective of any claim, setoff, defense or other right
which the Borrowers may have at any time against the Letter of Credit Issuer or
any other Person. Each drawing under any Letter of Credit shall constitute a
request by the Borrowers to the Lender for a Borrowing of a Base Rate Revolving
Loan in the amount of such drawing. The Funding Date with respect to such
Borrowing shall be the date of such drawing.

            (f) Indemnification; Power of Attorney.

                  (1) Indemnification. In addition to amounts payable as
            elsewhere provided in this Section 1.3, the Borrowers agree to
            protect, indemnify, pay and save the Lender harmless from and
            against any and all claims, demands, liabilities, damages, losses,
            costs, charges and expenses (including reasonable attorneys' fees)
            which the Lender (other than in its capacity as Letter of Credit
            Issuer) may incur or be subject to as a consequence, direct or
            indirect, of the issuance of any Letter of Credit or the provision
            of any Credit Support or enhancement in connection therewith. The
            Borrowers' obligations under this Section shall survive payment of
            all other Obligations.

                  (2) Assumption of Risk by the Borrowers. As between the
            Borrowers and the Lender, the Borrowers assume all risks of the acts
            and omissions of, or misuse of any of the Letters of Credit by, the
            respective beneficiaries of such Letters of Credit. In furtherance
            and not in limitation of the foregoing, the Lender shall not be
            responsible for:

                                     - 4 -
<PAGE>

            (A) the form, validity, sufficiency, accuracy, genuineness or legal
            effect of any document submitted by any Person and believed by the
            Lender in good faith to be valid, sufficient, accurate, genuine and
            authorized in connection with the application for and issuance of
            and presentation of drafts with respect to any of the Letters of
            Credit, even if it should prove to be in any or all respects
            invalid, insufficient, inaccurate, fraudulent or forged; (B) the
            validity or sufficiency of any instrument transferring or assigning
            or purporting to transfer or assign any Letter of Credit or the
            rights or benefits thereunder or proceeds thereof, in whole or in
            part, which the Lender in good faith believes to be valid and
            effective, but which may prove to be invalid or ineffective for any
            reason; (C) the failure of the beneficiary of any Letter of Credit
            to comply duly with conditions required in order to draw upon such
            Letter of Credit; (D) errors, omissions, interruptions, or delays in
            transmission or delivery of any messages, by mail, cable, telegraph,
            telex or otherwise, whether or not they be in cipher; (E) errors in
            interpretation of technical terms; (F) any loss or delay in the
            transmission or otherwise of any document required in order to make
            a drawing under any Letter of Credit or of the proceeds thereof; (G)
            the misapplication by the beneficiary of any Letter of Credit of the
            proceeds of any drawing under such Letter of Credit; (H) any
            consequences arising from causes beyond the control of the Lender,
            including any act or omission, whether rightful or wrongful, of any
            present or future de jure or de facto Governmental Authority; or (I)
            the Letter of Credit Issuer's honor of a draw for which the draw or
            any certificate fails to comply in any respect with the terms of the
            Letter of Credit. None of the foregoing shall affect, impair or
            prevent the vesting of any rights or powers of the Lender under this
            Section 1.3(f).

                  (3) Rights Against Letter of Credit Issuer. Nothing contained
            in this Agreement is intended to limit the Borrowers' rights, if
            any, with respect to the Letter of Credit Issuer which shall be
            governed by the letter of credit application and related documents
            executed by and between the Borrowers and the Letter of Credit
            Issuer.

                  (4) Account Party. The Borrowers hereby authorize and direct
            any Letter of Credit Issuer to name the Borrowers as the "Account
            Party" therein and to deliver to the Lender all instruments,
            documents and other writings and property received by the Letter of
            Credit Issuer pursuant to the Letter of Credit, and to accept and
            rely upon the Lender's instructions and agreements with respect to
            all matters arising in connection with the Letter of Credit or the
            application therefor.

            (g) Supporting Letter of Credit; Cash Collateral. If,
notwithstanding the provisions of Section 1.3(b) and Section 10.1, any Letter of
Credit or Credit Support is outstanding upon the termination of this Agreement,
then upon such termination the Borrowers shall deposit with the Lender, with
respect to each Letter of Credit or Credit Support then outstanding, a standby
letter of credit (a "Supporting Letter of Credit") in form and substance
reasonably satisfactory to the Lender, issued by an issuer reasonably
satisfactory to the Lender in an amount equal to the greatest amount for which
such Letter of Credit or such Credit Support may be drawn plus any fees and
expenses associated with such Letter of Credit or such Credit Support, under
which Supporting Letter of Credit the Lender is entitled to draw amounts
necessary to reimburse the Lender for payments to be made by the Lender under
such Letter of Credit or Credit Support and any reasonable fees and expenses
associated with such Letter of Credit or Credit Support. Such Supporting Letter
of Credit shall be held by the Lender as security for, and to provide for the
payment of, the aggregate undrawn amount of such Letters of Credit or such
Credit Support remaining outstanding.

      1.4 Bank Products. Subject to the terms of Section 7.25, the Borrowers may
request and the Lender may, in its sole and absolute discretion, arrange for the
Borrowers to obtain from the Bank or the Bank's Affiliates Bank Products
although the Borrowers are not required to do so. If Bank Products are provided
by an Affiliate of the Bank, the Borrowers agree to indemnify and hold the
Lender and the Bank harmless from any and all costs and obligations now or
hereafter incurred by the Bank or the Lender which arise from any indemnity
given by the Lender to its Affiliates related to such Bank Products; provided,
however, nothing contained herein is intended to limit the Borrowers' rights,
with respect to the Bank or its Affiliates, if any, which arise as a result of
the execution of documents by and between the Borrowers and the Bank which
relate to Bank Products. The agreement contained in this Section shall survive
termination of this Agreement. The Borrowers acknowledge and agree that the
obtaining of Bank Products from the Bank or the Bank's Affiliates (a) is in the
sole and absolute discretion of the Bank or the Bank's Affiliates, and (b) is
subject to all rules and regulations of the Bank or the Bank's Affiliates.

                                INTEREST AND FEES

      2.1 Interest.

            (a) Interest Rates. All outstanding Obligations shall bear interest
on the unpaid principal amount thereof (including, to the extent permitted by
law, on interest thereon not paid when due) from the date made until paid in
full in cash at a rate determined by reference to the Base Rate or the LIBOR
Rate plus the Applicable Margins as set forth below, but not to exceed the
Maximum Rate. If at any time Loans are outstanding with respect to which the
Borrowers have not delivered to the Lender a notice specifying the basis for
determining the interest rate applicable thereto in accordance herewith, those
Loans shall bear interest at a rate determined by reference to the Base Rate
until notice to the contrary has been given to the Lender in accordance with
this Agreement and such notice has become effective. Except as otherwise
provided herein, the outstanding Obligations shall bear interest as follows:

                  (i) For all Base Rate Revolving Loans and other Obligations
      (other than LIBOR Revolving Loans) at a fluctuating per annum rate equal
      to the Base Rate plus the Applicable Margin; and

                  (ii) For all LIBOR Revolving Loans at a per annum rate equal
      to the LIBOR Rate plus the Applicable Margin.

Each change in the Base Rate shall be reflected in the interest rate applicable
to Base Rate Revolving Loans as of the effective date of such change. All
interest charges shall be computed on the basis of a year of 360 days and actual
days elapsed (which results in more interest being paid than if computed on the
basis of a 365-day year). The Borrowers shall pay to the Lender interest accrued
on all Base Rate Revolving Loans in arrears on the first day of each month
hereafter and on the Termination Date. The Borrowers shall pay to the Lender
interest on all LIBOR Revolving Loans in arrears on each LIBOR Interest Payment
Date.

            (b) Default Rate. If any Default or Event of Default occurs and is
continuing and the Lender in its discretion so elects, then, while any such
Default or Event of Default is continuing, all of the Obligations shall bear
interest at the Default Rate applicable thereto.

      2.2 Continuation and Conversion Elections.

            (a) The Borrowers may:

                  (i) elect, as of any Business Day, in the case of Base Rate
      Revolving Loans to convert any Base Rate Revolving Loans (or any part
      thereof in an amount not less than $1,000,000, or that is in an integral
      multiple of $500,000 in excess thereof) into LIBOR Revolving Loans; or

                  (ii) elect, as of the last day of the applicable Interest
      Period, to continue any LIBOR Revolving Loans having Interest Periods
      expiring on such day (or any part thereof in an amount not less than
      $1,000,000, or that is in an integral multiple of $500,000 in excess
      thereof);

provided, that if at any time the aggregate amount of LIBOR Revolving Loans in
respect of any Borrowing is reduced, by payment, prepayment, or conversion of
part thereof to be less than $1,000,000, such LIBOR Revolving Loans shall
automatically convert into Base Rate Revolving Loans; provided further, that if
the notice shall fail to specify the duration of the Interest Period, such
Interest Period shall be one month.

            (b) The Borrowers shall deliver a notice of continuation/conversion
("Notice of Continuation/Conversion") to the Lender not later than 12:00 noon
(Los Angeles time) at least three (3) Business Days in advance of the
Continuation/Conversion Date, if the Loans are to be converted into or continued
as LIBOR Revolving Loans and specifying:

                  (i) the proposed Continuation/Conversion Date;

                  (ii) the aggregate amount of Loans to be converted or renewed;

                  (iii) the type of Loans resulting from the proposed conversion
      or continuation; and

                  (iv) the duration of the requested Interest Period, provided,
      however, the Borrowers may not select an Interest Period that ends after
      the Stated Termination Date.

            (c) If, upon the expiration of any Interest Period applicable to
LIBOR Revolving Loans, the Borrowers have failed to select timely a new Interest
Period to be applicable to LIBOR Revolving Loans or if any Default or Event of
Default then exists, the Borrowers shall be deemed to have elected to convert
such LIBOR Revolving Loans into Base Rate Revolving Loans effective as of the
expiration date of such Interest Period.

            (d) There may not be more than five (5) different LIBOR Revolving
Loans in effect hereunder at any time.

      2.3 Maximum Interest Rate. In no event shall any interest rate provided
for hereunder exceed the maximum rate legally chargeable by the Lender under
applicable law with respect to loans of the type provided for hereunder (the
"Maximum Rate"). If, in any month, any interest rate, absent such limitation,
would have exceeded the Maximum Rate, then the interest rate for that month
shall be the Maximum Rate, and, if in future months, that interest rate would
otherwise be less than the Maximum Rate, then that interest rate shall remain at
the Maximum Rate until such time as the amount of interest paid hereunder equals
the amount of interest which would have been paid if the same had not been
limited by the Maximum Rate. In the event that, upon payment in full of the
Obligations, the total amount of

                                     - 7 -
<PAGE>

interest paid or accrued under the terms of this Agreement is less than the
total amount of interest which would, but for this Section 2.3, have been paid
or accrued if the interest rate otherwise set forth in this Agreement had at all
times been in effect, then the Borrower shall, to the extent permitted by
applicable law, pay the Lender an amount equal to the excess of (a) the lesser
of (i) the amount of interest which would have been charged if the Maximum Rate
had, at all times, been in effect or (ii) the amount of interest which would
have accrued had the interest rate otherwise set forth in this Agreement, at all
times, been in effect over (b) the amount of interest actually paid or accrued
under this Agreement. If a court of competent jurisdiction determines that the
Lender has received interest and other charges hereunder in excess of the
Maximum Rate, such excess shall be deemed received on account of, and shall
automatically be applied to reduce, the Obligations other than interest, in the
inverse order of maturity, and if there are no Obligations outstanding, the
Lender shall refund to the Borrowers such excess.

      2.4 Closing Fee. The Borrowers agree to pay the Lender on the Closing Date
a closing fee (the "Closing Fee") in the amount of $120,000.

      2.5 Unused Line Fee. On the first day of each month and on the Termination
Date the Borrowers agree to pay to the Lender an unused line fee (the "Unused
Line Fee") equal to three hundred seventy-five thousandths of one percent
(0.375%) per annum times the amount by which the Maximum Revolver Amount
exceeded the sum of the average daily outstanding amount of Revolving Loans and
the average daily undrawn face amount of outstanding Letters of Credit, during
the immediately preceding month or shorter period if calculated for the first
month hereafter or on the Termination Date. The Unused Line Fee shall be
computed on the basis of a 360-day year for the actual number of days elapsed.
All principal payments received by the Lender shall be deemed to be credited to
the Borrowers' Loan Account immediately upon receipt for purposes of calculating
the Unused Line Fee pursuant to this Section 2.5.

      2.6 Letter of Credit Fee. The Borrowers agree to pay to (a) the Lender for
each Letter of Credit, a fee (the "Letter of Credit Fee") equal to one and
one-half percent (1.5%) per annum, (b) the Lender for the benefit of the Letter
of Credit Issuer, a fronting fee of one-quarter of one percent (0.25%) per annum
of the undrawn face amount of each Letter of Credit, and (c) the Letter of
Credit Issuer, all out-of-pocket costs, fees and expenses reasonably incurred by
the Letter of Credit Issuer in connection with the application for, processing
of, issuance of, or amendment to any Letter of Credit. The Letter of Credit Fee
with respect to each Letter of Credit shall be payable monthly in arrears on the
first day of each month following any month in which such Letter of Credit is
outstanding and on the Termination Date. The Letter of Credit Fee shall be
computed on the basis of a 360-day year for the actual number of days elapsed.

                                    ARTICLE 3
                            PAYMENTS AND PREPAYMENTS

      3.1 Revolving Loans. The Borrowers shall repay the outstanding principal
balance of the Revolving Loans, plus all accrued but unpaid interest thereon, on
the Termination Date. The Borrowers may prepay Revolving Loans at any time, and
reborrow subject to the terms of this Agreement. In addition, and without
limiting the generality of the foregoing, upon demand the Borrowers shall pay to
the Lender the amount, without duplication, by which the Aggregate Revolver
Outstandings exceeds the lesser of the Borrowing Base or the Maximum Revolver
Amount.

      3.2 Termination of Facility. The Borrowers may terminate this Agreement
upon at least ten (10) Business Days' notice to the Lender, upon (a) the payment
in full of all outstanding Revolving Loans, together with accrued interest
thereon, and the cancellation and return of all outstanding Letters of Credit or
the delivery of a back-to-back letter of credit in accordance with Section
1.3(g), (b) the prepayment of

                                     - 8 -
<PAGE>

the early termination fee set forth below, (c) the payment in full in cash of
all reimbursable expenses and other Obligations, and (d) with respect to any
LIBOR Revolving Loans prepaid, payment of the amounts due under Section 4.4, if
any. If this Agreement is terminated at any time prior to the Stated Termination
Date, whether pursuant to this Section or pursuant to Section 9.2, the Borrowers
shall pay to the Lender an early termination fee determined in accordance with
the following table:

<TABLE>

        PERIOD DURING WHICH
         EARLY TERMINATION                               EARLY TERMINATION
             OCCURS                                             FEE
         -----------------                               -----------------

    On or prior to the first Anniversary              2.0% of the Total Facility
    Date

    After the first Anniversary Date but on
    or prior to the Termination Date                  0.5% of the Total Facility
</TABLE>

Notwithstanding the foregoing, in the event that the Borrowers refinance the
Total Facility after the first Anniversary Date with a credit facility provided
by another lending department of the Bank, the early termination fee shall not
apply. The early termination fee shall be reduced to 1% of the Total Facility
if, on or prior to the first Anniversary Date, (i) all amounts due hereunder are
paid in full as a result of a sale or merger of the Borrowers or their
Subsidiaries to which the Lender does not provide its consent under Section 7.9,
(ii) the Borrowers have complied with Section 1.3(g), and (iii) this Credit
Agreement has been terminated.

      3.3 LIBOR Revolving Loan Prepayments. In connection with any prepayment,
if any LIBOR Revolving Loans are prepaid prior to the expiration date of the
Interest Period applicable thereto, the Borrowers shall pay to the Lender the
amounts described in Section 4.4.

      3.4 Payments by the Borrowers.

            (a) All payments to be made by the Borrowers shall be made without
set-off, recoupment or counterclaim. Except as otherwise expressly provided
herein, all payments by the Borrowers shall be made to the Lender, at the
account designated by the Lender and shall be made in Dollars and in immediately
available funds, no later than 12:00 noon (Los Angeles time) on the date
specified herein. Any payment received by the Lender after such time shall be
deemed (for purposes of calculating interest only) to have been received on the
following Business Day and any applicable interest shall continue to accrue.

            (b) Subject to the provisions set forth in the definition of
"Interest Period", whenever any payment is due on a day other than a Business
Day, such payment shall be due on the following Business Day, and such extension
of time shall in such case be included in the computation of interest or fees,
as the case may be.

      3.5 Payments as Revolving Loans. At the election of the Lender, all
payments of principal, interest, reimbursement obligations in connection with
Letters of Credit and Credit Support for Letters of Credit, fees, premiums,
reimbursable expenses and other sums payable hereunder, may be paid from the
proceeds of Revolving Loans made hereunder. The Borrowers hereby irrevocably
authorize the Lender to charge the Loan Account for the purpose of paying all
amounts from time to time due hereunder and agree that all such amounts charged
shall constitute Revolving Loans.

      3.6 Apportionment, Application and Reversal of Payments. Principal and
interest payments and payments of the fees shall be payable solely to the Lender
(except for fees payable to the Letter of Credit Issuer if different than the
Lender). All payments shall be remitted to the Lender and all such payments not
relating to principal or interest of specific Loans, or not constituting payment
of specific fees, and all proceeds of Accounts or other Collateral received by
the Lender, shall be applied, ratably, subject to the provisions of this
Agreement, first, to pay any fees, indemnities or expense reimbursements,
including any amounts relating to Bank Products, then due to the Lender from the
Borrowers; second, to pay interest due in respect of all Loans; third, to pay or
prepay principal of the Revolving Loans and unpaid reimbursement obligations in
respect of Letters of Credit; fourth, to pay an amount to Lender equal to all
outstanding Letter of Credit Obligations to be held as cash collateral for such
Obligations; and fifth, to the payment of any other Obligation due to the Lender
by the Borrowers. Notwithstanding anything to the contrary contained in this
Agreement, unless so directed by the Borrowers, or unless an Event of Default
has occurred and is continuing, the Lender shall not apply any payments which it
receives to any LIBOR Revolving Loan, except (a) on the expiration date of the
Interest Period applicable to any such LIBOR Revolving Loan, or (b) in the
event, and only to the extent, that there are no outstanding Base Rate Revolving
Loans and, in any event, the Borrowers shall pay LIBOR breakage losses in
accordance with Section 4.4. Upon the occurrence and during the continuation of
an Event of Default, the Lender shall have the continuing and exclusive right to
apply and reverse and reapply any and all such proceeds and payments to any
portion of the Obligations.

      3.7 Indemnity for Returned Payments. If after receipt of any payment which
is applied to the payment of all or any part of the Obligations, the Lender, the
Bank or any Affiliate of the Bank is for any reason compelled to surrender such
payment or proceeds to any Person because such payment or application of
proceeds is invalidated, declared fraudulent, set aside, determined to be void
or voidable as a preference, impermissible setoff, or a diversion of trust
funds, or for any other reason, then the Obligations or part thereof intended to
be satisfied shall be revived and continued and this Agreement shall continue in
full force as if such payment or proceeds had not been received by the Lender
and the Borrowers shall be liable to pay to the Lender, and do hereby indemnify
the Lender and hold the Lender harmless for the amount of such payment or
proceeds surrendered. The provisions of this Section 3.7 shall be and remain
effective notwithstanding any contrary action which may have been taken by the
Lender in reliance upon such payment or application of proceeds, and any such
contrary action so taken shall be without prejudice to the Lender's rights under
this Agreement and shall be deemed to have been conditioned upon such payment or
application of proceeds having become final and irrevocable. The provisions of
this Section 3.7 shall survive the termination of this Agreement.

      3.8 Lender's Books and Records; Monthly Statements. The Lender shall
record the principal amount of the Loans owing to the Lender, the undrawn face
amount of all outstanding Letters of Credit and the aggregate amount of unpaid
reimbursement obligations outstanding with respect to the Letters of Credit from
time to time on its books. In addition, the Lender may note the date and amount
of each payment or prepayment of principal of the Loans in its books and
records. Failure by the Lender to make such notation shall not affect the
obligations of the Borrowers with respect to the Loans or the Letters of Credit.
The Borrowers agree that the Lender's books and records showing the Obligations
and the transactions pursuant to this Agreement and the other Loan Documents
shall be admissible in any action or proceeding arising therefrom, and shall
constitute rebuttably presumptive proof thereof, irrespective of whether any
Obligation is also evidenced by a promissory note or other instrument. The
Lender will provide to the Borrowers a monthly statement of Loans, payments, and
other transactions pursuant to this Agreement. Such statement shall be deemed
correct, accurate, and binding on the Borrowers and an account stated (except
for corrections of errors discovered by the Lender), unless the Borrowers notify
the Lender in writing to the contrary within thirty (30) days after such
statement is rendered. In the event a timely written notice of objections is
given by the Borrowers, only the items to which exception is expressly made will
be considered to be disputed by the Borrowers.

                                    ARTICLE 4
                     TAXES, YIELD PROTECTION AND ILLEGALITY

      4.1 Taxes.

            (a) Any and all payments by the Borrowers to the Lender under this
Agreement and any other Loan Document shall be made free and clear of, and
without deduction or withholding for, any Taxes. In addition, the Borrowers
shall pay all Other Taxes.

            (b) The Borrowers agree to indemnify and hold harmless the Lender
for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes
imposed by any jurisdiction on amounts payable under this Section) paid in good
faith by the Lender and any liability (including penalties, interest, additions
to tax and expenses) arising therefrom or with respect thereto, whether or not
such Taxes or Other Taxes were correctly or legally asserted. Payment under this
indemnification shall be made within 30 days after the date the Lender makes
written demand therefor.

            (c) If the Borrowers shall be required by law to deduct or withhold
any Taxes or Other Taxes from or in respect of any sum payable hereunder to the
Lender, then:

                  (i) the sum payable shall be increased as necessary so that
      after making all required deductions and withholdings (including
      deductions and withholdings applicable to additional sums payable under
      this Section), the Lender receives an amount equal to the sum it would
      have received had no such deductions or withholdings been made;

                  (ii) the Borrowers shall make such deductions and
      withholdings;

                  (iii) the Borrowers shall pay the full amount deducted or
      withheld to the relevant taxing authority or other authority in accordance
      with applicable law; and

                  (iv) the Borrowers shall also pay to the Lender, at the time
      interest is paid, all additional amounts which the Lender reasonably
      specifies as necessary to preserve the after-tax yield the Lender would
      have received if such Taxes or Other Taxes had not been imposed.

            (d) At the Lender's request, within 30 days after the date of any
payment by the Borrowers of Taxes or Other Taxes, the Borrowers shall furnish
the Lender the original or a certified copy of a receipt evidencing payment
thereof, or other evidence of payment reasonably satisfactory to the Lender.

            (e) If the Borrowers are required to pay additional amounts to the
Lender pursuant to subsection (c) of this Section, then the Lender shall use
reasonable efforts (consistent with legal and regulatory restrictions) to change
the jurisdiction of its lending office so as to eliminate any such additional
payment by the Borrowers which may thereafter accrue, if such change in the
judgment of the Lender is not otherwise disadvantageous to the Lender.

      4.2 Illegality.

            (a) If the Lender determines that the introduction of any
Requirement of Law, or any change in any Requirement of Law, or in the
interpretation or administration of any Requirement of Law, has made it
unlawful, or that any central bank or other Governmental Authority has asserted
that it is unlawful, for the Lender or its applicable lending office to make
LIBOR Revolving Loans, then, on notice thereof by the Lender to the Borrowers,
any obligation of the Lender to make LIBOR Revolving Loans

                                     - 11 -
<PAGE>

shall be suspended until the Lender notifies the Borrowers that the
circumstances giving rise to such determination no longer exist.

            (b) If the Lender determines that it is unlawful to maintain any
LIBOR Revolving Loan, the Borrowers shall, upon their receipt of notice of such
fact and demand from the Lender, prepay in full such LIBOR Revolving Loans then
outstanding, together with interest accrued thereon and amounts required under
Section 4.4, either on the last day of the Interest Period thereof, if the
Lender may lawfully continue to maintain such LIBOR Revolving Loans to such day,
or immediately, if the Lender may not lawfully continue to maintain such LIBOR
Revolving Loans. If the Borrowers are required to so prepay any LIBOR Revolving
Loans, then concurrently with such prepayment, the Borrowers shall borrow from
the Lender, in the amount of such prepayment, a Base Rate Revolving Loan.

      4.3 Increased Costs and Reduction of Return.

            (a) If the Lender determines that due to either (i) the introduction
after the date hereof of or any change after the date hereof in the
interpretation of any law or regulation or (ii) the compliance by the Lender
with any guideline or request from any central bank or other Governmental
Authority (whether or not having the force of law), there shall be any increase
in the cost to the Lender of agreeing to make or making, funding or maintaining
any LIBOR Revolving Loans, then the Borrowers shall be liable for, and shall
from time to time, upon demand, pay to the Lender additional amounts as are
sufficient to compensate the Lender for such increased costs.

            (b) If the Lender shall have determined that (i) the introduction
after the date hereof of any Capital Adequacy Regulation, (ii) any change after
the date hereof in any Capital Adequacy Regulation, (iii) any change after the
date hereof in the interpretation or administration of any Capital Adequacy
Regulation by any central bank or other Governmental Authority charged with the
interpretation or administration thereof, or (iv) compliance by the Lender or
any corporation or other entity controlling the Lender with any such Capital
Adequacy Regulation, affects or would affect the amount of capital required or
expected to be maintained by the Lender or any corporation or other entity
controlling the Lender and (taking into consideration its policies with respect
to capital adequacy and the Lender's desired return on capital) determines that
the amount of such capital is increased as a consequence of its Commitments,
loans, credits or obligations under this Agreement, then, upon demand of the
Lender to the Borrowers, the Borrowers shall pay to the Lender, from time to
time as specified by the Lender, additional amounts sufficient to compensate the
Lender for such increase.

      4.4 Funding Losses. The Borrowers shall reimburse the Lender and hold the
Lender harmless from any loss or expense which the Lender may sustain or incur
as a consequence of:

            (a) the failure of the Borrowers to make on a timely basis any
payment of principal of any LIBOR Revolving Loan;

            (b) the failure of the Borrowers to borrow, continue or convert a
Loan after the Borrowers have given (or are deemed to have given) a Notice of
Borrowing or a Notice of Continuation/Conversion; or

            (c) the prepayment or other payment (including after acceleration
thereof) of any LIBOR Revolving Loans on a day that is not the last day of the
relevant Interest Period; including any such loss of anticipated profit and any
loss or expense arising from the liquidation or reemployment of funds obtained
by it to maintain its LIBOR Revolving Loans or from fees payable to terminate
the deposits from which such funds were obtained. The Borrowers shall also pay
any customary administrative fees charged by the Lender in connection with the
foregoing.

                                     - 12 -
<PAGE>

      4.5 Inability to Determine Rates. If the Lender reasonably determines that
for any reason adequate and reasonable means do not exist for determining the
LIBOR Rate for any requested Interest Period with respect to a proposed LIBOR
Revolving Loan, or that the LIBOR Rate for any requested Interest Period with
respect to a proposed LIBOR Revolving Loan does not adequately and fairly
reflect the cost to the Lender of funding such Loan, the Lender will promptly so
notify the Borrowers. Thereafter, the obligation of the Lender to make or
maintain LIBOR Revolving Loans hereunder shall be suspended until the Lender
revokes such notice in writing. Upon receipt of such notice, the Borrowers may
revoke any Notice of Borrowing or Notice of Continuation/Conversion then
submitted by it. If the Borrowers do not revoke such Notice, the Lender shall
make, convert or continue the Loans, as proposed by the Borrowers, in the amount
specified in the applicable notice submitted by the Borrowers, but such Loans
shall be made, converted or continued as Base Rate Revolving Loans instead of
LIBOR Revolving Loans.

      4.6 Certificates of Lender. If the Lender claims reimbursement or
compensation under this Article 4, it shall determine the amount thereof and
shall deliver to the Borrowers a certificate setting forth in reasonable detail
the amount payable to the Lender, and such certificate shall be conclusive and
binding on the Borrowers in the absence of manifest error.

      4.7 Survival. The agreements and obligations of the Borrowers in this
Article 4 shall survive the payment of all other Obligations.

                                    ARTICLE 5

and perform this Agreement and the other Loan Documents to which they are a
party, to incur the Obligations, and to grant to the Lender Liens upon and
security interests in the Collateral owned by the Borrowers. The Borrowers have
taken all necessary action (including obtaining approval of its stockholders if

Agreement and the other Loan Documents to which they are a party. This Agreement

and delivered by the Borrowers, and constitute the legal, valid and binding
obligations of the Borrowers, enforceable against them in accordance with their
respective terms. The Borrowers' execution, delivery, and performance of this
Agreement and the other Loan Documents to which they are a party do not and will
not conflict with, or constitute a violation or breach of, or result in the

contract, mortgage, lease, agreement, indenture, or instrument to which the
Borrowers are a party or which is binding upon them, (b) any Requirement of Law

or articles of incorporation or by-laws or the limited liability company or
limited partnership agreement of the Borrowers or any of their Subsidiaries.

      6.2 Validity and Priority of Security Interest. The provisions of this
Agreement and the other Loan Documents create legal and valid Liens on all the
Collateral in favor of the Lender, and such Liens, when all appropriate filings
have been made by the Lender in the applicable jurisdictions, will constitute
perfected and continuing Liens on all the Collateral, having priority over all
other Liens on the Collateral except for those Liens identified in clauses (c),
(d) and (e) of the definition of Permitted Liens securing all the Obligations,
and enforceable against the Borrowers and all third parties.

or incorporated and validly existing in good standing under the laws of the
state of their organization or incorporation, (b) are qualified to do business
and are in good standing in the jurisdictions set forth on Schedule 6.3, which
are the only jurisdictions in which qualification is necessary in order for them
to own or lease their property and conduct their business, and (c) have all
requisite power and authority to conduct their business and to own their
property.

      6.4 Corporate Name; Prior Transactions. Except as set forth on Schedule
6.4, the Borrowers have not, during the past five (5) years, been known by or
used any other corporate or fictitious name, or been a party to any merger or
consolidation, or acquired all or substantially all of the assets of any Person,
or acquired any of their property outside of the ordinary course of business.

      6.5 Subsidiaries and Affiliates. Schedule 6.5 is a correct and complete
list of the name and relationship to each Borrower of each and all of the
Borrowers' Subsidiaries. Each Subsidiary is (a) duly incorporated or organized
and validly existing in good standing under the laws of its state of
incorporation or organization set forth on Schedule 6.5, and (b) qualified to do
business and in good standing in each jurisdiction in which the failure to so
qualify or be in good standing could reasonably be expected to have a material
adverse effect on any such Subsidiary's business, operations, prospects,
property, or condition (financial or otherwise) and (c) has all requisite power
and authority to conduct its business and own its property.

expeditious manner with materials and workmanship of substantially the same
quality as existed before the loss, damage or destruction so long as (i) no
Default or Event of Default has occurred and is continuing, and (ii) the
Borrowers or Spacelabs Quebec, as applicable, first (A) provide the Lender with
plans and specifications for any such repair or restoration which shall be
reasonably satisfactory to the Lender, and (B) demonstrate to the reasonable
satisfaction of the Lender that the funds available to it will be sufficient to
complete such project in the manner provided therein. In all other
circumstances, the Lender shall apply such insurance and condemnation proceeds,
ratably, to the reduction of the Obligations in the order provided for in
Section 3.6.

      7.7 Environmental Laws.

            (a) Each of the Borrowers shall, and shall cause each of its
Subsidiaries to, conduct its business in material compliance with all
Environmental Laws applicable to it, including those relating to the generation,
handling, use, storage, and disposal of any Contaminant. Each of the Borrowers
shall, and shall cause each of its Subsidiaries to, take prompt and appropriate
action to respond to any material non-compliance with Environmental Laws and
shall regularly report to the Lender on such response.

            (b) Without limiting the generality of the foregoing, the Borrowers
shall submit to the Lender annually, commencing on the first Anniversary Date,
and on each Anniversary Date thereafter, an update of the status of each
instance of environmental non-compliance or environmental liability that could
reasonably be expected to result in liability to the Borrowers (in remediation,
restoration or settlement costs or otherwise) in excess of $1,000,000. The
Lender may request copies of technical reports prepared by the Borrowers and
their communications with any Governmental Authority to determine whether the
Borrowers or any of their Subsidiaries are proceeding reasonably to correct,
cure or contest in good faith any alleged non-compliance or environmental
liability. The Borrowers shall, at the Lender's request and at the Borrowers'
expense, (i) retain an independent environmental engineer reasonably acceptable
to the Lender to evaluate the site, including tests if appropriate, where the
non-compliance or alleged non-compliance with Environmental Laws has occurred
and prepare and deliver to the Lender a report setting forth the results of such
evaluation, a proposed plan for responding to any environmental problems
described therein, and an estimate of the costs thereof, and (ii) provide to

                                     - 25 -
<PAGE>

the Lender a supplemental report of such engineer whenever the scope of the
environmental problems, or the response thereto or the estimated costs thereof,
shall increase in any material respect.

            (c) The Lender and its representatives will have the right upon
reasonable notice to the Borrowers or Spacelabs Quebec, as applicable, at any
reasonable time to enter and visit the Real Estate and any other place where any
property of the Borrowers or Spacelabs Quebec is located for the purposes of
observing the Real Estate, taking and removing soil or groundwater samples, and
conducting tests on any part of the Real Estate. The Lender is under no duty,
however, to visit or observe the Real Estate or to conduct tests, and any such
acts by the Lender will be solely for the purposes of protecting the Lender's
Liens and preserving the Lender's rights under the Loan Documents. No site
visit, observation or testing by the Lender will result in a waiver of any
default of the Borrowers or impose any liability on the Lender. In no event will
any site visit, observation or testing by the Lender be a representation that
hazardous substances are or are not present in, on or under the Real Estate, or
that there has been or will be compliance with any Environmental Law. Neither
the Borrowers nor any other party is entitled to rely on any site visit,
observation or testing by the Lender. The Lender owes no duty of care to protect
the Borrowers or any other party against, or to inform the Borrower or any other
party of, any hazardous substances or any other adverse condition affecting the
Real Estate. The Lender shall disclose to the Borrowers, or to any other party,
if so required by law any report or findings made as a result of, or in
connection with, any site visit, observation or testing by the Lender. The
Borrowers understand and agree that the Lender makes no warranty or
representation to the Borrowers or any other party regarding the truth, accuracy
or completeness of any such report or findings that may be disclosed. The
Borrowers also understand that depending on the results of any site visit,
observation or testing by the Lender and disclosed to the Borrowers, the
Borrowers may have a legal obligation to notify one or more environmental
agencies of the results, that such reporting requirements are site-specific, and
are to be evaluated by the Borrowers without advice or assistance from the
Lender. In each instance, the Lender will give the Borrowers reasonable notice
before entering the Real Estate or any other place the Lender is permitted to
enter under this Section 7.7(c). The Lender will make reasonable efforts to
avoid interfering with the Borrowers' or Spacelabs Quebec's use of the Real
Estate or any other property in exercising any rights provided hereunder.

      7.8 Compliance with ERISA. The Borrowers shall, and shall cause each of
their ERISA Affiliates to: (a) maintain each Plan in compliance in all material
respects with the applicable provisions of ERISA, the Code and other federal or
state law; (b) cause each Plan which is qualified under Section 401(a) of the
Code to maintain such qualification; (c) make all required contributions to any
Plan subject to Section 412 of the Code; (d) not engage in a prohibited
transaction or violation of the fiduciary responsibility rules with respect to
any Plan; and (e) not engage in a transaction that could be subject to Section
4069 or 4212(c) of ERISA.

      7.9 Mergers, Consolidations or Sales. Neither the Borrowers nor any of
their Subsidiaries shall enter into any transaction of merger, reorganization,
or consolidation, or transfer, sell, assign, lease, or otherwise dispose of all
or any part of its property, or wind up, liquidate or dissolve, or agree to do
any of the foregoing, except (a) that with the prior written consent of the
Lender, which may be granted or withheld in Lender's sole discretion, the
Borrowers may merge with or into a company having a financial condition that is
equal to or better than that of the Borrowers at the time immediately prior to
such merger; (b) for sales of Inventory in the ordinary course of its business;
(c) in addition to sales and other dispositions of Equipment as set forth in
subsection (d) hereof, for sales or other dispositions of Equipment with an
orderly liquidation value not to exceed $500,000 in any Fiscal Year; (d) in
addition to sales and other dispositions of Equipment as set forth in subsection
(c) hereof, for sales or other dispositions of Equipment in connection with the
outsourcing of printed circuit board assembly, not to exceed an aggregate of
$1,000,000 in any Fiscal Year, and (e) for discounting of international letters
of credit issued for the account of a foreign customer that is not an Affiliate
of the Borrowers, provided that

                                     - 26 -
<PAGE>

the discounting is consistent with current practices of the Borrower and in no
event more than ten percent (10%) less than the amount due under the relevant
invoices. Within 120 days following each such Equipment sale or disposition
described in subsection (c) or (d) hereof, the Borrowers or Spacelabs Quebec, as
applicable, shall either (i) reinvest the proceeds of that sale or disposition
in other Equipment, or (ii) apply such proceeds to the Loans in accordance with
Section 3.6.

indirect Subsidiary of Spacelabs Delaware may declare and make a Distribution if
such Distribution is (A) paid to a Borrower, or (B) paid to a Subsidiary that is
not a Borrower, if the Subsidiary receiving such Distribution makes a
simultaneous and commensurate Distribution to a Borrower or to another entity
that makes a simultaneous and commensurate Distribution to a Borrower, and (ii)
Spacelabs Delaware may declare and make Distributions payable solely in the

Borrowers and their Subsidiaries during any Fiscal Year does not exceed
$5,000,000; (d) Debt evidencing a refunding, renewal or extension of the Debt
described on Schedule 6.9, provided that (i) the principal amount thereof is not

the Debt to be refunded, renewed or extended, (iii) no Person that is not an
obligor or guarantor of such Debt as of the Closing Date shall become an obligor
or guarantor thereof, and (iv) the terms of such refunding, renewal or extension

forfeiture of any material portion of the Collateral;

            (n) for any reason other than the failure of the Lender to take any

the Loan Documents, any Loan Document ceases to be in full force and effect or

            (o) an ERISA Event shall occur with respect to a Pension Plan or

other

                                     - 33 -
<PAGE>

elements used in computing the Borrowing Base; (ii) restrict the amount of or
refuse to make Revolving Loans, and (iii) restrict or refuse to provide Letters
of Credit or Credit Support. If an Event of Default exists, the Lender may, in
its discretion, do one or more of the following in addition to the actions
described in the preceding sentence, at any time or times and in any order,
without notice to or demand on the Borrowers: (A) terminate the Commitments and
this Agreement; (B) declare any or all Obligations to be immediately due and
payable, provided, however, that upon the occurrence of any Event of Default
described in Sections 9.1(e), 9.1(f), 9.1(g), or 9.1(h), the Commitments shall
automatically and immediately expire and all Obligations shall automatically
become immediately due and payable without notice or demand of any kind; (C)
require the Borrowers to cash collateralize all outstanding Letter of Credit
Obligations; and (D) pursue its other rights and remedies under the Loan

            (b) If an Event of Default has occurred and is continuing: (i) the
Lender shall have in addition to all other rights of the Lender, the rights and
remedies of a secured party under the Loan Documents and the UCC; (ii) the
Lender may, at any time, take possession of the Collateral and keep it on the
premises of the Borrowers or Spacelabs Quebec, as applicable, at no cost to the
Lender, or remove any part of it to such other place or places as the Lender may
desire, or the Borrowers or Spacelabs Quebec, as applicable, shall, upon the
Lender's demand, at the cost of the Borrowers or Spacelabs Quebec, as
applicable, assemble the Collateral and make it available to the Lender at a
place reasonably convenient to the Lender; and (iii) the Lender may sell and
deliver any Collateral at public or private sales, for cash, upon credit or
otherwise, at such prices and upon such terms as the Lender deems advisable, in
its sole discretion, and may, if the Lender deems it reasonable, postpone or
adjourn any sale of the Collateral by an announcement at the time and place of
sale or of such postponed or adjourned sale without giving a new notice of sale.
Without in any way requiring notice to be given in the following manner, the
Borrowers agree that any notice by the Lender of sale, disposition or other
intended action hereunder or in connection herewith, whether required by the UCC
or otherwise, shall constitute reasonable notice to the Borrowers or Spacelabs
Quebec, as applicable, if such notice is mailed by registered or certified mail,
return receipt requested, postage prepaid, or is delivered personally against
receipt, at least ten (10) Business Days prior to such action to the Borrowers'
addresses specified in or pursuant to Section 12.8 or pursuant to Section ___ of
the Spacelabs Quebec Guaranty. If any Collateral is sold on terms other than
payment in full at the time of sale, no credit shall be given against the
Obligations until the Lender receives payment, and if the buyer defaults in
payment, the Lender may resell the Collateral without further notice to the
Borrowers or Spacelabs Quebec. In the event the Lender seeks to take possession
of all or any portion of the Collateral by judicial process, the Borrowers
irrevocably waive: (A) the posting of any bond, surety or security with respect
thereto which might otherwise be required; (B) any demand for possession prior
to the commencement of any suit or action to recover the Collateral; and (C) any
requirement that the Lender retain possession and not dispose of any Collateral
until after trial or final judgment. The Borrowers agree that the Lender has no
obligation to preserve rights to the Collateral or marshal any Collateral for
the benefit of any Person. The Lender is hereby granted a license or other right
to use, without charge, the Borrowers' labels, patents, copyrights, name, trade
secrets, trade names, trademarks, and advertising matter, or any similar
property, in completing production of, advertising or selling any Collateral,
and the Borrowers' rights under all licenses and all franchise agreements shall
inure to the Lender's benefit for such purpose. The proceeds of sale shall be
applied first to all expenses of sale, including reasonable attorneys' fees, and
then to the Obligations in the order set forth in Section 3.6. The Lender will
return any excess to the Borrowers and the Borrowers shall remain liable for any
deficiency.

            (c) If an Event of Default has occurred and is continuing, the
Borrowers hereby waive all rights to notice and hearing prior to the exercise by
the Lender of the Lender's rights to repossess the Collateral without judicial
process or to reply, attach or levy upon the Collateral without notice or
hearing.

                              TERM AND TERMINATION

      10.1 Term and Termination. The term of this Agreement shall end on the
Stated Termination Date unless sooner terminated in accordance with the terms
hereof. The Lender may terminate this Agreement without notice upon the
occurrence and during the continuation of an Event of Default. Upon the
effective date of termination of this Agreement for any reason whatsoever, all
Obligations (including all unpaid principal, accrued and unpaid interest and any
early termination or prepayment fees or penalties) shall become immediately due
and payable and the Borrowers shall immediately arrange for the cancellation and
return of Letters of Credit then outstanding or shall cash collateralize such
Letters of Credit or provide standby letters of credit in accordance with
Section 1.3. Notwithstanding the termination of this Agreement, until all
Obligations are paid and performed in full in cash, the Borrowers shall remain
bound by the terms of this Agreement and shall not be relieved of any of their
Obligations hereunder or under any other Loan Document, and the Lender shall
retain all its rights and remedies hereunder (including the Lender's Liens in
and all rights and remedies with respect to all then existing and after-arising
Collateral).

                                   ARTICLE 11
                       AMENDMENTS; WAIVERS; PARTICIPATIONS

      11.1 Amendments and Waivers. No amendment or waiver of any provision of
this Agreement or any other Loan Document, and no consent with respect to any
departure by the Borrowers therefrom, shall be effective unless the same shall
be in writing and signed by the Lender and the Borrowers and then any such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given.

      11.2 Participations.

            (a) The Lender may, without the consent of the Borrowers, at any
time sell to one or more commercial banks, financial institutions, or other
Persons not Affiliates of the Borrowers (a "Participant") participating
interests in any Loans, the Commitment of the Lender and the other interests of
the Lender hereunder and under the other Loan Documents; provided, however, that
(i) the Lender's obligations under this Agreement shall remain unchanged, (ii)
the Lender shall remain solely responsible for the performance of such
obligations, (iii) the Borrowers shall continue to deal solely and directly with
the Lender in connection with the Lender's rights and obligations under this
Agreement and the other Loan Documents, (iv) the Lender shall not transfer or
grant any participating interest under which the Participant has rights to
approve any amendment to, or any consent or waiver with respect to, this
Agreement or any other Loan Document except with respect to (1) an increase or
extension of the Commitment of Lender or (2) postponement or delay of any date
fixed by this Agreement or any other Loan Document for any payment of principal,
interest, fees or other amounts due to Lender hereunder or under any other Loan
Document, and (v) all amounts payable by the Borrowers hereunder shall be
determined as if the Lender had not sold such participation; except that, if
amounts outstanding under this Agreement are due and unpaid, or shall have
become due and payable upon the occurrence of an Event of Default, each
Participant shall be deemed to have the right of set-off in respect of its
participating interest in amounts owing under this Agreement to the same extent
and subject to the same limitation as if the amount of its participating
interest were owing directly to it as a Lender under this Agreement.

            (b) The Lender may, without the consent of the Borrowers, assign
this Agreement (i) in connection with any assignment occurring by operation of
law, or (ii) upon the occurrence and during the continuation of an Event of
Default; in all other instances, the Lender may assign this

                                     - 35 -
<PAGE>

Agreement only upon the written consent of the Borrowers, which consent shall
not be unreasonably withheld.

            (c) Notwithstanding any other provision in this Agreement, the
Lender may at any time create a security interest in, or pledge, all or any
portion of its rights under and interest in this Agreement in favor of any
Federal Reserve Bank in accordance with Regulation A of the FRB or U.S. Treasury
Regulation 31 CFR Section 203.14, and such Federal Reserve Bank may enforce such
pledge or security interest in any manner permitted under applicable law.

                                   ARTICLE 12
                                  MISCELLANEOUS

      12.1 No Waivers; Cumulative Remedies. No failure by the Lender to exercise
any right, remedy, or option under this Agreement or any present or future
supplement thereto, or in any other agreement between the Borrowers and the
Lender, or delay by the Lender in exercising the same, will operate as a waiver
thereof. No waiver by the Lender will be effective unless it is in writing, and
then only to the extent specifically stated. No waiver by the Lender on any
occasion shall affect or diminish the Lender's rights thereafter to require
strict performance by the Borrowers of any provision of this Agreement. The
Lender may proceed directly to collect the Obligations without any prior
recourse to the Collateral. The Lender's rights under this Agreement will be
cumulative and not exclusive of any other right or remedy which the Lender may
have.

      12.2 Severability. The illegality or unenforceability of any provision of
this Agreement or any Loan Document or any instrument or agreement required
hereunder shall not in any way affect or impair the legality or enforceability
of the remaining provisions of this Agreement or any instrument or agreement
required hereunder.

      12.3 Governing Law; Choice of Forum; Service of Process.

            (a) THIS AGREEMENT SHALL BE INTERPRETED AND THE RIGHTS AND
LIABILITIES OF THE PARTIES HERETO DETERMINED IN ACCORDANCE WITH THE INTERNAL
LAWS (AS OPPOSED TO THE CONFLICT OF LAWS PROVISIONS PROVIDED THAT PERFECTION
ISSUES WITH RESPECT TO ARTICLE 9 OF THE UCC MAY GIVE EFFECT TO APPLICABLE CHOICE
OR CONFLICT OF LAW RULES SET FORTH IN ARTICLE 9 OF THE UCC) OF THE STATE OF
WASHINGTON; PROVIDED THAT THE LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER
FEDERAL LAW.

            (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR
ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF WASHINGTON
OR OF THE UNITED STATES OF AMERICA LOCATED IN KING COUNTY, WASHINGTON, AND BY
EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH OF THE BORROWERS AND THE LENDER
CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE
JURISDICTION OF THOSE COURTS. EACH OF THE BORROWERS AND THE LENDER IRREVOCABLY
WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON
THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY ACTION OR PROCEEDING IN SUCH COURTS IN RESPECT OF THIS AGREEMENT
OR ANY DOCUMENT RELATED HERETO. NOTWITHSTANDING THE FOREGOING: (1) THE LENDER
SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST THE BORROWERS OR
THEIR PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION THE LENDER DEEMS
NECESSARY OR APPROPRIATE IN ORDER TO REALIZE ON THE

                                     - 36 -
<PAGE>

COLLATERAL OR OTHER SECURITY FOR THE OBLIGATIONS AND (2) EACH OF THE PARTIES
HERETO ACKNOWLEDGES THAT ANY APPEALS FROM THE COURTS DESCRIBED IN THE
IMMEDIATELY PRECEDING SENTENCE MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE
THOSE JURISDICTIONS.

            (c) THE BORROWERS HEREBY WAIVE PERSONAL SERVICE OF ANY AND ALL
PROCESS UPON THEM AND CONSENT THAT ALL SUCH SERVICE OF PROCESS MAY BE MADE BY
REGISTERED MAIL (RETURN RECEIPT REQUESTED) DIRECTED TO THE BORROWERS AT THEIR
ADDRESSES SET FORTH IN SECTION 12.8 AND SERVICE SO MADE SHALL BE DEEMED TO BE
COMPLETED FIVE (5) DAYS AFTER THE SAME SHALL HAVE BEEN SO DEPOSITED IN THE U.S.
MAIL POSTAGE PREPAID. NOTHING CONTAINED HEREIN SHALL AFFECT THE RIGHT OF THE
LENDER TO SERVE LEGAL PROCESS BY ANY OTHER MANNER PERMITTED BY LAW.

            (d) NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT TO THE
CONTRARY, ANY CONTROVERSY OR CLAIM BETWEEN THE PARTIES, ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, INCLUDING ANY CLAIM BASED
ON OR ARISING FROM AN ALLEGED TORT, SHALL AT THE REQUEST OF EITHER PARTY HERETO
BE DETERMINED BY BINDING ARBITRATION. The arbitration shall be conducted in
accordance with the United States Arbitration Act (Title 9, U.S. Code),
notwithstanding any choice of law provision in this Agreement, and under the
Commercial Rules of the American Arbitration Association ("AAA"). The
arbitrator(s) shall give effect to statutes of limitation in determining any
claim. Any controversy concerning whether an issue is arbitrable shall be
determined by the arbitrator(s). Judgment upon the arbitration award may be
entered in any court having jurisdiction. The institution and maintenance of an
action for judicial relief or pursuant to a provisional or ancillary remedy
shall not constitute a waiver of the right of either party, including the
plaintiff, to submit the controversy or claim to arbitration if any other party
contests such action for judicial relief.

            (e) At the request of either party a controversy or claim which is
not submitted to arbitration as provided and limited in Section 12.3(d) shall be
determined by judicial reference. If such an election is made, the parties shall
designate to the court a referee or referees selected under the auspices of the
AAA in the same manner as arbitrators are selected in AAA-sponsored proceedings.
The presiding referee of the panel, or the referee if there is a single referee,
shall be an active attorney or retired judge. Judgment upon the award rendered
by such referee or referees shall be entered in the court in which such
proceeding was commenced.

            (f) No provision of Sections 12.3(d) or 12.3(e) shall limit the
right of the Lender to exercise self-help remedies such as setoff, foreclosure
against or sale of any real or personal property collateral or security, or
obtaining provisional or ancillary remedies from a court of competent
jurisdiction before, after, or during the pendency of any arbitration or other
proceeding. The exercise of a remedy does not waive the right of either party to
resort to arbitration or reference. At the Lender's option, foreclosure under a
deed of trust or mortgage may be accomplished either by exercise of power of
sale under the deed of trust or mortgage or by judicial foreclosure.

      12.4 WAIVER OF JURY TRIAL. SUBJECT TO THE PROVISIONS OF SECTION 12.3(d),
THE BORROWERS AND THE LENDER EACH IRREVOCABLY WAIVE THEIR RESPECTIVE RIGHTS TO A
TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF OR
RELATED TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY, IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF
ANY TYPE BROUGHT BY ANY OF THE PARTIES AGAINST ANY OTHER PARTY OR ANY
LENDER-RELATED PERSON OR PARTICIPANT,

                                     - 37 -
<PAGE>

WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE. THE
BORROWERS AND THE LENDER EACH AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL
BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE
PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED
BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING
WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF
THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF.
THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
MODIFICATIONS TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

      12.5 Survival of Representations and Warranties. All of the Borrowers'
representations and warranties contained in this Agreement shall survive the
execution, delivery, and acceptance thereof by the parties, notwithstanding any
investigation by the Lender or its agents.

      12.6 Other Security and Guaranties. The Lender may, without notice or
demand and without affecting the Borrowers' obligations hereunder, from time to
time: (a) take from any Person and hold collateral (other than the Collateral)
for the payment of all or any part of the Obligations and exchange, enforce or
release such collateral or any part thereof; and (b) accept and hold any
endorsement or guaranty of payment of all or any part of the Obligations and
release or substitute any such endorser or guarantor, or any Person who has
given any Lien in any other collateral as security for the payment of all or any
part of the Obligations, or any other Person in any way obligated to pay all or
any part of the Obligations.

      12.7 Fees and Expenses. The Borrowers agree to pay to the Lender, for its
benefit, on demand, all reasonable costs and expenses that Lender pays or incurs
in connection with the negotiation, preparation, consummation, administration,
enforcement, and termination of this Agreement or any of the other Loan
Documents, including: (a) Attorney Costs; (b) reasonable costs and expenses
(including reasonable attorneys' and paralegals' fees and disbursements) for any
amendment, supplement, waiver, consent, or subsequent closing in connection with
the Loan Documents and the transactions contemplated thereby; (c) reasonable
costs and expenses of lien and title searches and title insurance; (d) taxes,
fees and other charges for filing financing statements and continuations, and
other actions to perfect, protect, and continue the Lender's Liens (including
reasonable costs and expenses paid or incurred by the Lender in connection with
the consummation of Agreement); (e) reasonable sums paid or incurred to pay any
amount or take any action required of the Borrowers under the Loan Documents
that the Borrowers fail to pay or take; (f) costs of appraisals, inspections,
and verifications of the Collateral, including reasonable travel, lodging, and
meals for inspections of the Collateral and the Borrowers' operations by the
Lender plus the Lender's then customary charge for field examinations and audits
and the preparation of reports thereof (such charge is currently $750 per day
(or portion thereof) for each Person retained or employed by the Lender with
respect to each field examination or audit); and (g) reasonable and customary
costs and expenses of forwarding loan proceeds, collecting checks and other
items of payment, and establishing and maintaining Payment Accounts and lock
boxes, and costs and expenses of preserving and protecting the Collateral. In
addition, the Borrowers agree to pay reasonable costs and expenses incurred by
the Lender (including Attorneys' Costs) to the Lender, on demand, paid or
incurred to obtain payment of the Obligations, enforce the Lender's Liens, sell
or otherwise realize upon the Collateral, and otherwise enforce the provisions
of the Loan Documents, or to defend any claims made or threatened against the
Lender arising out of the transactions contemplated hereby (including
preparations for and consultations concerning any such matters). The foregoing
shall not be construed to limit any other provisions of the Loan Documents
regarding costs and expenses to be paid by the Borrowers. All of the foregoing
costs and expenses shall be charged to the Borrower's Loan Account as Revolving
Loans as described in Section 3.5.

      12.9 Waiver of Notices. Unless otherwise expressly provided herein, the
Borrowers waive presentment, and notice of demand or dishonor and protest as to
any instrument, notice of intent to accelerate the Obligations and notice of
acceleration of the Obligations, as well as any and all other notices to which
it might otherwise be entitled. No notice to or demand on the Borrowers which
the Lender may elect to give shall entitle the Borrowers to any or further
notice or demand in the same, similar or other circumstances.

      12.10 Binding Effect. The provisions of this Agreement shall be binding
upon and inure to the benefit of the respective representatives, successors, and
assigns of the parties hereto; provided, however, that no interest herein may be
assigned by the Borrowers without prior written consent of the Lender. The
rights and benefits of the Lender hereunder shall, if such Persons so agree,
inure to any party acquiring any interest in the Obligations or any part
thereof.

      12.11 Indemnity of the Lender by the Borrowers.

            (a) The Borrowers agree to defend, indemnify and hold the
Lender-Related Persons (each, an "Indemnified Person") harmless from and against
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, charges, expenses and disbursements (including Attorney
Costs) of any kind or nature whatsoever which may at any time (including at any
time following repayment of the Loans and the termination or replacement of the
Lender) be imposed on, incurred by or asserted against any such Person in any
way relating to or arising out of this Agreement or any document contemplated by
or referred to herein, or the transactions contemplated hereby, or any action
taken or omitted by any such Person under or in connection with any of the
foregoing, including with respect to any investigation, litigation or proceeding
(including any Insolvency Proceeding or appellate proceeding) related to or
arising out of this Agreement, any other Loan Document, or the Loans or the use
of the proceeds thereof, whether or not any Indemnified Person is a party
thereto (all the foregoing, collectively, the "Indemnified Liabilities");
provided, that the Borrowers shall have no obligation hereunder to any
Indemnified Person with respect to Indemnified Liabilities resulting from the
gross negligence or willful misconduct of such Indemnified Person. The
agreements in this Section shall survive payment of all other Obligations.

            (b) The Borrowers agree to indemnify, defend and hold harmless the
Lender from any loss or liability directly or indirectly arising out of the use,
generation, manufacture, production, storage, release, threatened release,
discharge, disposal or presence of a hazardous substance relating to the
Borrowers' operations, business or property. This indemnity will apply whether
the hazardous substance is on, under or about the Borrowers' property or
operations or property leased to the Borrowers. The indemnity includes but is
not limited to Attorneys Costs. The indemnity extends to the Lender, its
parents, affiliates, subsidiaries and all of their directors, officers,
employees, agents, successors, attorneys and assigns. "Hazardous substances"
means any substance, material or waste that is or becomes designated or
regulated as "toxic," "hazardous," "pollutant," or "contaminant" or a similar
designation or regulation under any federal, state or local law (whether under
common law, statute, regulation or otherwise) or judicial or administrative
interpretation of such, including petroleum or natural gas. This indemnity will
survive repayment of all other Obligations. In the event any Indemnified Person
intends to seek indemnity under this Section 12.11, it shall give Spacelabs
Delaware prompt written notice thereof and shall allow Spacelabs Delaware an
opportunity to participate in, or the defense of, any investigation, litigation
or proceeding related thereto.

      12.12 Limitation of Liability. EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN
THIS AGREEMENT, NO CLAIM MAY BE MADE BY ANY PARTY OR OTHER PERSON AGAINST THE
OTHER PARTY, OR ITS AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES, COUNSEL,
REPRESENTATIVES, AGENTS OR ATTORNEYS-IN-FACT FOR ANY SPECIAL,

                                     - 40 -
<PAGE>

INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES IN RESPECT OF ANY CLAIM FOR BREACH
OF CONTRACT OR ANY OTHER THEORY OF LIABILITY ARISING OUT OF OR RELATED TO THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY
ACT, OMISSION OR EVENT OCCURRING IN CONNECTION THEREWITH, AND THE PARTIES HEREBY
WAIVE, RELEASE AND AGREE NOT TO SUE UPON ANY CLAIM FOR SUCH DAMAGES, WHETHER OR
NOT ACCRUED AND WHETHER OR NOT KNOWN OR SUSPECTED TO EXIST IN ITS FAVOR.

      12.13 Final Agreement. This Agreement and the other Loan Documents are
intended by the Borrowers and the Lender to be the final, complete, and
exclusive expression of the agreement between them. This Agreement and the other
Loan Documents supersede any and all prior oral or written agreements relating
to the subject matter hereof. No modification, rescission, waiver, release, or
amendment of any provision of this Agreement or any other Loan Document shall be
made, except by a written agreement signed by the Borrowers and a duly
authorized officer of the Lender.

      12.14 Counterparts. This Agreement may be executed in any number of
counterparts, and by the Lender and the Borrowers in separate counterparts, each
of which shall be an original, but all of which shall together constitute one
and the same agreement; signature pages may be detached from multiple separate
counterparts and attached to a single counterpart so that all signature pages
are physically attached to the same document.

      12.15 Captions. The captions contained in this Agreement are for
convenience of reference only, are without substantive meaning and should not be
construed to modify, enlarge, or restrict any provision.

      12.16 Right of Setoff. In addition to any rights and remedies of the
Lender provided by law, if an Event of Default exists or the Loans have been
accelerated, the Lender is authorized at any time and from time to time, without
prior notice to the Borrowers, any such notice being waived by the Borrower to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held by,
and other indebtedness at any time owing by, the Lender or any Affiliate of the
Lender to or for the credit or the account of the Borrowers against any and all
Obligations due and payable to such Lender, now or hereafter existing,
irrespective of whether or not the Lender shall have made demand under this
Agreement or any Loan Documents and although such Obligations may be contingent
or unmatured. The Lender agrees promptly to notify the Borrowers after any such
set-off and application made by the Lender; provided, however, that the failure
to give such notice shall not affect the validity of such set-off and
application.

      12.17 Joint and Several Liability and Related Matters. Notwithstanding any
other provision of this Agreement or the Loan Documents, all obligations of the
Borrowers under this Agreement and the other Loan Documents are joint and
several primary obligations of the Borrowers; provided, however, that the
liability of each of the Borrowers is limited to the greater of (i) the maximum
liability that such Borrower can incur hereunder without rendering itself
insolvent, or (ii) the dollar amount of the value received by such Borrower as a
result of the financial accommodations made available by the Lender to the
Borrowers (the "Maximum Obligation"). The terms "value" and "insolvent," as used
in this Section 12.17, shall have the same meanings as in 11 U.S.C. Sections
548(a)(2)(A) and (B), respectively. If for any reason a Borrower's agreement
under the Loan Documents to be jointly and severally liable for the Obligations
would otherwise be avoidable as a fraudulent transfer under the Debtor Relief
Laws notwithstanding the foregoing limitation on such Borrower's liability, then
the terms "value" and "insolvent" as used herein shall be defined and the
limitation on liability shall be deemed to operate in such a manner as to
prevent such Borrower's agreement to be jointly and severally liable for the

                                     - 41 -
<PAGE>

Obligations from being avoided as a fraudulent transfer while at the same time
preserving such Borrower's liability to the maximum extent possible. Each
Borrower acknowledges that:

            (a) It will derive substantial and direct benefits from the
transactions contemplated by this Agreement and the other Loan Documents;

            (b) It would not be able on its own to obtain financing on terms as
favorable as those set forth in this Agreement;

            (c) The Lender would not extend financing to the Borrower under this
Agreement unless the Borrower agreed to be jointly and severally liable for the
Obligations;

            (d) It has received, will receive, or has the right to receive
consideration that is the reasonable equivalent of the obligations and liability
that it has incurred to the Lender;

            (e) It is not insolvent as defined in Section 101 of the Bankruptcy
Code or any applicable Debtor Relief Law, nor, after giving effect to the
consummation of the transactions contemplated by this Agreement and the other
Loan Documents, will it be rendered insolvent by its execution and delivery to
the Lender of this Agreement and the other Loan Documents to which it is a
party;

            (f) It is not engaged or about to be engaged in any business or
transaction for which the assets retained by it will be unreasonably small
capital, taking into consideration its obligations to the Lender under this
Agreement; and

            (g) It does not intend to, or believe that it will, incur debts
beyond its ability to pay them as they mature.

In the event any Borrower (the "Funding Borrower") shall make a payment in
respect of any of the Loans or any other Obligations or shall suffer any loss as
a result of any realization upon any of its assets pursuant to any Loan
Document, each other Borrower (a "Contributing Borrower") shall, subject to the
last sentence of this Section 12.17, contribute to such Funding Borrower an
amount equal to such Contributing Borrower's Pro Rata Share of such payment
made, or loss suffered, by such Funding Borrower. Each Contributing Borrower's
"Pro Rata Share" with respect to any such payment or loss by the Funding
Borrower shall be determined as of the date on which such payment or loss was
made or suffered by reference to the ratio of (i) such Contributing Borrower's
Maximum Obligation as of such date (without giving effect to any right to
receive, or obligation to make, any contribution hereunder) to (ii) the
aggregate Maximum Obligations of all Borrowers (including such Funding Borrower)
as of such date (without giving effect to any right to receive, or obligation to
make, any contribution hereunder). Nothing in this paragraph of Section 12.17
shall affect each Borrower's joint and several liability for the entire amount
of the Obligations (up to such Borrower's Maximum Obligation). Each Borrower
covenants and agrees that its obligation to make a contribution hereunder to a
Funding Borrower and its right to receive any contribution hereunder from a
Contributing Borrower shall be subordinate and junior in right of payment to the
Obligations.

      12.18 Confidentiality. The Lender agrees to comply in all respects with
that certain Non-Disclosure Agreement dated as of February 6, 2001 between the
Lender and Spacelabs Delaware.

      12.19 Conflicts with Other Loan Documents. Unless otherwise expressly
provided in this Agreement (or in another Loan Document by specific reference to
the applicable provision contained in this Agreement), if any provision
contained in this Agreement conflicts with any provision of any other Loan
Document, the provision contained in this Agreement shall govern and control.

THE BORROWERS ACKNOWLEDGE THAT ORAL AGREEMENTS OR ORAL COMMITMENTS TO LOAN
MONEY, EXTEND CREDIT, OR TO FORBEAR FROM ENFORCING REPAYMENT OF A DEBT ARE NOT
ENFORCEABLE UNDER WASHINGTON LAW.

      IN WITNESS WHEREOF, the parties have entered into this Agreement on the
date first above written.

Delware's chief financial officer, setting forth in reasonable detail the basis

Agreement, result in an increase in the Applicable Margins to the highest level
set forth in the foregoing grid, until the first day of the first calendar month

cured.

general economic conditions and other factors, and is used as a reference point
for pricing some loans, which may be priced at, above, or below such announced
rate). Any change in the prime rate announced by the Bank shall take effect at

change. Each Interest Rate based upon the Base Rate shall be adjusted

Borrowing Base in connection with the preparation of any Borrowing Base
Certificate shall originally be made by the Borrowers and certified to the
Lender; provided, that the Lender shall have the right to review and adjust, in
the exercise of its reasonable credit judgment, any such calculation (1) to

accordance with this Agreement.

negotiations among and have been reviewed by counsel to the Lender, the
Borrowers and the other parties, and are the products of all parties.

           (e) If, following the date of this Agreement, any Grantor becomes the
beneficiary of a letter of credit, each such letter of credit shall permit the
assignment of the beneficiary's interest thereunder, and if Lender so requests,
Grantor shall promptly notify the Lender thereof and enter into a tri-party
agreement with the Lender and the issuer and/or confirmation bank with respect
to Letter-of-Credit Rights assigning such Letter-of-Credit Rights to the Lender

financing statement filed as a fixture filing, a sufficient description of real
property to which the Collateral relates. The Grantors agree to furnish any such
information to the Lender promptly upon request. The Grantors also ratify their
authorization for the Lender to have filed in any Uniform Commercial Code
jurisdiction any like initial financing statements or amendments thereto if
filed prior to the date hereof.

           (h) The Grantors shall promptly notify the Lender of any commercial
tort claim (as defined in the UCC) acquired by them and unless otherwise
consented by the Lender, the Grantors shall enter into a supplement to this
Security Agreement, granting to the Lender a Lien in such commercial tort claim.

<PAGE>

           (i) From time to time, the Grantors shall, upon the Lender's
reasonable request, execute and deliver confirmatory written instruments
pledging to the Lender the Collateral, but the Grantors' failure to do so shall

and to the Collateral with respect to the Grantors. So long as the Credit
Agreement is in effect and until all Obligations have been fully satisfied, the
Lender's Liens shall continue in full force and effect in all Collateral

accommodation).

each calendar year, each Grantor shall, upon the request of Lender, provide to
the Lender a certificate of good standing from its state of incorporation or
organization.

           (k) No Reincorporation. Without limiting the prohibitions on mergers
involving the Grantors contained in the Credit Agreement, no Grantor shall
reincorporate or reorganize itself under the laws of any jurisdiction other than
the jurisdiction in which it is incorporated or organized as of the date hereof
or change its type of entity as identified on Schedule II without the prior
written consent of the Lender.

           (l) Terminations Amendments Not Authorized. The Grantors acknowledge
that they are not authorized to file any financing statement or amendment or
termination statement with respect to any financing statement without the prior
written consent of the Lender and agree that they will not do so without the
prior written consent of the Lender, subject to the Grantors' rights under RCW
Section 9A-509(d)(2).

           (m) No Restriction on Payments to Lender. Except as expressly
permitted in the Credit Agreement, the Grantors shall not enter into any
Contract that restricts or prohibits the grant of a security interest in
Accounts, Chattel Paper, Instruments or payment intangibles or the proceeds of
the foregoing to the Lender.

        4. LOCATION OF COLLATERAL.

           (a) The Grantors represent and warrant to the Lender that: (A)
Schedule I is a correct and complete list of the location of each Grantor's
chief executive office, the location of its books and records, the locations of
the Collateral, and the locations of all of its other places of business; and
(B) Schedule I correctly identifies any of such facilities and locations that
are not owned by the Grantors and sets forth the names of the owners and lessors
or sublessors of such facilities and locations. The Grantors covenant and agree
that, except as otherwise expressly permitted in the Credit Agreement, they will
not (i) maintain any Collateral at any location other than those locations
listed for the Grantors on Schedule I, (ii) otherwise change or add to any of
such locations, or (iii) change the location of any chief executive office from
the locations identified in Schedule I, unless in each case they give the Lender
at least thirty (30) days' prior written notice thereof and execute any and all
financing statements and other documents that the Lender reasonably requests in
connection therewith. Without limiting the foregoing, the Grantors represent
that all of their Inventory (other than Inventory in transit and Inventory on
consignment in the normal course of business consistent with past practices) is,
and covenants that all of its Inventory will be, located either (a) on premises
owned by the Grantors, (b) on premises leased by the Grantors, or (c) in a
warehouse or with a bailee. Grantors shall use good faith efforts to obtain,
within one hundred eighty (180) days of the date of this Agreement, an executed
landlord waiver from the landlords of Grantors' premises located in Redmond,
Washington and Deerfield, Wisconsin, in form and substance reasonably
satisfactory to the Lender. In any event, Grantors shall provide such waivers to
the Lender prior to an Inventory Activation Date, together with an executed
bailee letter from the applicable Person authorized to execute such letters for
each warehouse in which Inventory is stored, in form and

                                      -6-

Grantor (including corporation, partnership, limited partnership or limited
liability company), organizational identification number issued by each
Grantor's state of incorporation or organization or a statement that no such
number has been issued, and the jurisdiction in which each Grantor is
incorporated or organized. The Grantors have only those states of incorporation
or organization as are identified on Schedule II.

expressly permitted under the Credit Agreement; (b) the Lender Liens in the
Collateral will not be subject to any prior Lien except for those Liens
identified in clauses (c), (d) and (e) of the definition of Permitted Liens and
liens otherwise expressly permitted under the Credit Agreement; and (c) the
Grantors will use, store, and maintain the Collateral with all reasonable care
and will use such Collateral for lawful purposes only.

        7. APPRAISALS. Prior to an Inventory Activation Date, Grantors shall, at
their expense, provide the Lender with an appraisal of all of the Inventory from
an appraiser, and prepared on a basis, reasonably satisfactory to the Lender,
such appraisal to include, without limitation, information required by
applicable law and regulation and by the internal policies of the Lender.
Thereafter, whenever a Default or Event of Default exists, and at such other
times not more frequently than once a year as the Lender requests, if the
Inventory is part of the Borrowing Base, the Grantors shall, at their expense
and upon the Lender's request, provide the Lender with an update thereof, such
update to be from an appraiser, and prepared on a basis, reasonably satisfactory
to the Lender, such updates to include, without limitation, information required
by applicable law and regulation and by the internal policies of the Lender.

        8. ACCESS AND EXAMINATION. Upon prior notice to the Grantors, the Lender
may at all reasonable times during regular business hours (and at any time when
a Default or Event of Default exists and is continuing) have access to, examine,
audit, make extracts from or copies of and inspect any or all of the Grantors'
records, files, and books of account and the Collateral, and discuss the
Grantors' affairs with the Grantors' officers and management. The Grantors will
deliver to the Lender any instrument reasonably necessary for the Lender to
obtain records from any service bureau maintaining records for the Grantors. The
Lender may at any time when a Default or Event of Default exists, and at the
Grantors' expense, make copies of all of the Grantors' books and records, or
require the Grantors to deliver such copies to the Lender. Without expense to
the Lender, the Grantors shall provide access to the Collateral, the cooperation
of its personnel, and the use of such supplies as may be reasonably necessary
for maintaining or enforcing the Lender's Liens. The Lender shall have the
right, at any reasonable time, in the Lender's name or in the name of a nominee
of the Lender, to verify the validity, amount or any other matter relating to
the Accounts, Inventory, or other Collateral, by mail, telephone, or otherwise.

Grantors' records or reports of the Collateral are prepared by an accounting
service or other agent, the Grantors hereby authorize such service or agent to
deliver such records, reports, and related documents to the Lender.

        10. ACCOUNTS.

            (a) The Grantors hereby represent and warrant to the Lender, with
respect to the Grantors' Accounts, that: (i) each existing Account represents,
and each future Account will represent, a bona fide sale or lease and delivery
of goods by the Grantors, or rendition of services by the Grantors, in the
ordinary course of the Grantors' businesses; (ii) each existing Account is, and
each future Account will be, for a liquidated amount payable by the Account
Debtor thereon on the terms set forth in the invoice therefor or in the schedule
thereof delivered to the Lender, without any offset, deduction, defense, or
counterclaim except those known to the Grantors and disclosed to the Lender
pursuant to this Security Agreement; (iii) no payment will be received with

will be a genuine copy of the original invoice sent to the Account Debtor named

described in each invoice will have been performed.

            (b) The Grantors shall not re-date any invoice or sale or make sales
on extended dating beyond that customary in the Grantors' businesses or extend
or modify any Account. If the Grantors become aware of any matter adversely
affecting the collectibility of any Account or the Account Debtor therefor
involving an amount greater than $250,000, including information regarding the
Account Debtor's creditworthiness, the Grantors will promptly so advise the
Lender and exclude such Account from Eligible Accounts.

            (c) The Grantors shall not accept any note or other instrument
(except a check or other instrument for the immediate payment of money) with
respect to any Account without the Lender's written consent. If the Lender
consents to the acceptance of any such instrument, it shall be considered as

deliver such instrument to the Lender, endorsed by the appropriate Grantor to
the Lender in a manner satisfactory in form and substance to the Lender.
Regardless of the form of presentment, demand, notice of protest with respect
thereto, the Grantors shall remain liable thereon until such instrument is paid
in full.

without the Lender's prior written consent, except for discounts, credits and
allowances made or given in the ordinary course of the Grantors' businesses when
no Event of Default exists hereunder. The Grantors shall send the Lender a copy
of each credit memorandum in excess of $250,000 as soon as issued, and the
Grantors shall promptly report that credit on Borrowing Base Certificates
submitted by them. The Lender may at all times when an Event of Default exists
hereunder, settle or adjust disputes and claims directly with Account Debtors
for amounts and upon terms which the Lender shall consider advisable and, in all
cases, the Lender will credit the Grantor's Loan Account with the net amounts
received by the Lender in payment of any Accounts.

            (e) If an Account Debtor returns any Inventory to the Grantors when
no Event of Default exists, then the Grantors shall promptly determine the
reason for such return and shall issue a credit memorandum to the Account Debtor
in the appropriate amount. The Grantors shall immediately report to the Lender
any return involving an amount in excess of $250,000. Each such report shall
indicate the reasons for the returns and the locations and condition of the
returned Inventory. In the event any Account Debtor returns Inventory to the
Grantors when an Event of Default exists, the Grantors, upon the request of the
Lender, shall: (i) hold the returned Inventory in trust for the Lender; (ii)
segregate all returned Inventory from all of their other property; (iii) dispose
of the returned Inventory solely according to the Lender's written instructions;
and (iv) unless the amount of such credit or allowance is less than $500, not
issue any credits or allowances with respect thereto without the Lender's prior
written consent. All returned Inventory shall be subject to the Lender's Liens
thereon. Whenever any Inventory is returned, the related Account shall be deemed
ineligible to the extent of the amount owing by the Account Debtor with respect
to such returned Inventory and such returned Inventory shall not be Eligible
Inventory.

        11. COLLECTION OF ACCOUNTS; PAYMENTS.

            (a) Until the Lender notifies the Borrowers to the contrary, the
Borrowers shall make collection of all Accounts and other Collateral for the
Lender, shall receive all payments as the Lender's trustee, and shall
immediately deliver all payments in their original form duly endorsed in blank
into a Payment Account established for the account of the Borrowers at a
Clearing Bank acceptable to the Lender, subject to a Blocked Account Agreement.
On or prior to the date hereof, the Borrowers shall establish one or more
lock-box services for collections of Accounts at a Clearing Bank reasonably
acceptable to the Lender and each subject to a Blocked Account Agreement and
other documentation reasonably acceptable to the Lender. The Borrowers shall
instruct all Account Debtors to make all payments directly to the applicable
address established for such service. If, notwithstanding such instructions, the
Borrowers receive any proceeds of Accounts, they shall receive such payments as
the Lender's trustee, and shall immediately deliver such payments to the Lender
in their original form duly endorsed in blank or deposit them into a Payment
Account, as the Lender may direct. All collections received in any lock-box or
Payment Account or directly by the Borrowers or the Lender, and all funds in any
Payment Account or other account to which such collections are deposited, shall
be subject to the Lender's sole control and withdrawals by the Borrowers shall
not be permitted. The Lender or the Lender's designee may, at any time after the
occurrence and during the continuation of an Event of Default, notify Account
Debtors that the Accounts have been assigned to the Lender and of the Lender's
security interest therein, and may collect them directly and charge the
collection costs and expenses to the Loan Account as a Revolving Loan. So long
as an Event of Default has occurred and is continuing, the Borrowers, at the
Lender's request, shall execute and deliver to the Lender such documents as the
Lender shall reasonably require to grant the Lender access to any post office
box in which collections of Accounts are received.

                                      -9-

<PAGE>

            (b) If sales of Inventory are made or services are rendered for
cash, the Borrowers shall immediately deliver to the Lender or deposit into a
Payment Account the cash which the Borrowers receive.

            (c) All payments, including immediately available funds received by
the Lender at a bank account designated by it, will be the Lender's sole
property for its benefit and will be credited to the Loan Account upon final
collection.

            (d) In the event the Borrowers repay all of the Obligations upon the
termination of the Credit Agreement or upon acceleration of the Obligations,
other than through the Lender's receipt of payments on account of the Accounts
or proceeds of the other Collateral, or in the event there are no outstanding
Obligations immediately prior to the termination of the Credit Agreement, such
payment will be credited to the Borrowers' Loan Account upon the Lender's
receipt of immediately available funds.

        12. INVENTORY; PERPETUAL INVENTORY.

            (a) The Grantors represent and warrant to the Lender and agree with
the Lender that all of the Inventory owned by the Grantors is and will be held
for sale or lease, or to be furnished in connection with the rendition of
services, in the ordinary course of the Grantors' businesses, and is and will be
fit for such purposes. The Grantors will keep their Inventory in good and
marketable condition, except for damaged or defective goods arising in the
ordinary course of the Grantors' businesses. The Grantors will not acquire or
accept any Inventory on consignment or approval without the prior written
consent of the Lender, which approval shall not be unreasonably withheld.
Grantor represents that as of the date of this Agreement, it has on consignment
or approval the Inventory described on Schedule I attached hereto. The Grantors
agree that all Inventory produced by the Grantors in the United States of
America will be produced in accordance with the Federal Fair Labor Standards Act
of 1938, as amended, and all rules, regulations, and orders thereunder. The
Grantors will continue to do cycle counting of Inventory in the ordinary course
of their businesses, consistent with past practices, and after and during the
continuation of an Event of Default, Grantors will conduct a physical count of
the Inventory if the Lender requests. The Grantors will maintain a perpetual
inventory reporting system at all times. The Grantors will not, without the
Lender's written consent, sell any Inventory on a bill-and-hold, guaranteed
sale, sale and return, sale on approval, other repurchase or return basis, or on
consignment (except in the ordinary course of their businesses, consistent with
past practices).

            (b) In connection with all Inventory financed by Letters of Credit,
the Grantors will, at the Lender's reasonable request, instruct all suppliers,
carriers, forwarders, customs brokers, warehouses or others receiving or holding
cash, checks, Inventory, Documents or Instruments in which the Lender holds a
security interest to deliver them to the Lender and/or subject to the Lender's
order, and if they shall come into the Grantors' possession, to deliver them,
upon request, to the Lender in their original form. The Grantors shall also, at
the Lender's request, designate the Lender as the consignee on all bills of
lading and other negotiable and non-negotiable documents.

        13. EQUIPMENT.

            (a) The Grantors represent and warrant to the Lender and agree with
the Lender that all of the Equipment owned by the Grantors and necessary for the
conduct of Grantors' businesses is and will be used or held for use in the
Grantors' businesses. The Grantors shall keep and maintain such Equipment in
good operating condition and repair (ordinary wear and tear excepted) and shall
make all necessary replacements thereof.

                                      -10-

<PAGE>

            (b) The Grantors shall promptly inform the Lender of any material
additions to or deletions from the Equipment. The Grantors shall not permit any
Equipment that is used in any of Grantors' manufacturing or production
processes, to become a fixture with respect to real property or to become an
accession with respect to other personal property with respect to which real or
personal property the Lender does not have a Lien, or any material part of
Grantors' other Equipment. The Grantors will not, without the Lender's prior
written consent, alter or remove any identifying symbol or number on any of the
Grantors' Equipment constituting Collateral.

            (c) Except as set forth in the Credit Agreement, the Grantors shall
not, without the Lender's prior written consent, sell, license, lease as a
lessor, or otherwise dispose of any of the Grantors' Equipment.

        14. DOCUMENTS, INSTRUMENTS AND CHATTEL PAPER. The Grantors represent and
warrant to the Lender that (a) all Documents, Instruments, and Chattel Paper
describing, evidencing, or constituting Collateral, and all signatures and
endorsements thereon, are and will be complete, valid, and genuine, and (b) all
goods evidenced by such Documents, Instruments, Letter of Credit Rights and
Chattel Paper are and will be owned by the Grantors, free and clear of all Liens
other than Permitted Liens and other liens expressly permitted in the Credit
Agreement. If the Grantors retain possession of any Chattel Paper or Instruments
with Lender's consent, such Chattel Paper and Instruments shall be marked with
the following legend: "This writing and the obligations evidenced or served
hereby are subject to the security interest of Bank of America, N.A., as
Lender."

        15. RIGHT TO CURE. The Lender may, in its discretion, pay any amount or
do any act required of the Grantors hereunder or under any other Loan Document
in order to preserve, protect, maintain or enforce the Obligations, the
Collateral or the Lender's Liens therein, and which the Grantors fail to pay or
do, including payment of any judgment against the Grantors, any insurance
premium, any warehouse charge, any finishing or processing charge, any
landlord's or bailee's claim, and any other Lien upon or with respect to the
Collateral. All reasonable payments that the Lender makes under this Section 15
and all reasonable out-of-pocket costs and expenses that the Lender pays or
incurs in connection with any action taken by it hereunder shall be charged to
the Grantors' Loan Account as a Revolving Loan. Any payment made or other action
taken by the Lender under this Section 15 shall be without prejudice to any
right to assert an Event of Default hereunder and to proceed thereafter as
herein provided.

        16. POWER OF ATTORNEY. Each Grantor hereby appoints the Lender and the
Lender's designee as such Grantor's attorney, with power: (a) to endorse such
Grantor's name on any checks, notes, acceptances, money orders, or other forms
of payment or security that come into the Lender's possession; (b) to sign such
Grantor's name on any invoice, bill of lading, warehouse receipt or other
negotiable or non-negotiable Document constituting Collateral, on drafts against
customers, on assignments of Accounts, on notices of assignment, financing
statements and other public records and to file any such financing statements by
electronic means with or without a signature as authorized or required by
applicable law or filing procedure; (c) so long as any Event of Default has
occurred and is continuing, to notify the post office authorities to change the
address for delivery of such Grantor's mail to an address designated by the
Lender and to receive, open and dispose of all mail addressed to such Grantor;
(d) to send requests for verification of Accounts to customers or Account
Debtors; (e) to complete in such Grantor's name or the Lender's name, any order,
sale or transaction, obtain the necessary Documents in connection therewith, and
collect the proceeds thereof; (f) to clear Inventory through customs in such
Grantor's name, the Lender's name or the name of the Lender's designee, and to
sign and deliver to customs officials powers of attorney in such Grantor's name
for such purpose; (g) to the extent that such Grantor's authorization given in
Section 3(g) of this Security Agreement is not sufficient, to file such
financing statements with respect to this Security Agreement, with or without
such Grantor's signature, or to file a photocopy of this Security Agreement in
substitution for a financing statement, as the Lender

                                      -11-

<PAGE>

may deem appropriate and to execute in such Grantor's name such financing
statements and amendments thereto and continuation statements which may require
such Grantor's signature; and (h) to do all things necessary to carry out the
Credit Agreement and this Security Agreement; provided, however, the Lender
hereby agrees not to exercise any of its rights granted by this power of
attorney unless an Event of Default has occurred and is continuing. Each Grantor
hereby ratifies and approves all acts of such attorney. Neither the Lender nor
its attorneys will be liable for any acts or omissions or for any error of
judgment or mistake of fact or law except for their gross negligence or willful
misconduct. This power, being coupled with an interest, is irrevocable until the
Credit Agreement has been terminated and the Obligations have been fully
satisfied.

        17. THE LENDER'S RIGHTS, DUTIES AND LIABILITIES.

            (a) The Grantors assume all responsibility and liability arising
from or relating to the use, sale, license or other disposition of the
Collateral. The Obligations shall not be affected by any failure of the Lender
to take any steps to perfect the Lender's Liens or to collect or realize upon
the Collateral, nor shall loss of or damage to the Collateral release the
Grantors from any of the Obligations. Following the occurrence and during the
continuation of an Event of Default, the Lender may (but shall not be required
to), without notice to or consent from the Grantors, sue upon or otherwise
collect, extend the time for payment of, modify or amend the terms of,
compromise or settle for cash, credit, or otherwise upon any terms, grant other
indulgences, extensions, renewals, compositions, or releases, and take or omit
to take any other action with respect to the Collateral, any security therefor,
any agreement relating thereto, any insurance applicable thereto, or any Person
liable directly or indirectly in connection with any of the foregoing, without
discharging or otherwise affecting the liability of the Grantors for the
Obligations or under the Credit Agreement or any other agreement now or
hereafter existing between the Lender and the Grantors.

            (b) It is expressly agreed by the Grantors that, anything herein to
the contrary notwithstanding, the Grantors shall remain liable under each of
their contracts and each of their licenses to observe and perform all the
conditions and obligations to be observed and performed by them thereunder. The
Lender shall not have any obligation or liability under any contract or license
by reason of or arising out of this Security Agreement or the granting herein of
a Lien thereon or the receipt by the Lender of any payment relating to any
contract or license pursuant hereto. The Lender shall not be required or
obligated in any manner to perform or fulfill any of the obligations of the
Grantors under or pursuant to any contract or license, or to make any payment,
or to make any inquiry as to the nature or the sufficiency of any payment
received by it or the sufficiency of any performance by any party under any
contract or license, or to present or file any claims, or to take any action to
collect or enforce any performance or the payment of any amounts which may have
been assigned to it or to which it may be entitled at any time or times.

            (c) The Lender may at any time after a Default or an Event of
Default has occurred and be continuing (or if any rights of set-off (other than
set-offs against an Account arising under the contract giving rise to the same
Account) or contra accounts may be asserted with respect to the following),
without prior notice to the Grantors, notify Account Debtors, and other Persons
obligated on the Collateral that the Lender has a security interest therein, and
that payments shall be made directly to the Lender. Upon the request of the
Lender, the Grantors shall so notify Account Debtors and other Persons obligated
on Collateral. Once any such notice has been given to any Account Debtor or
other Person obligated on the Collateral, the Grantors shall not give any
contrary instructions to such Account Debtor or other Person without the
Lender's prior written consent.

                                      -12-

<PAGE>

            (d) The Lender may at any time in the Lender's own name or in the
name of the Grantors communicate with Account Debtors, parties to Contracts and
obligors in respect of Instruments to verify with such Persons, to the Lender's
satisfaction, the existence, amount and terms of Accounts, payment intangibles,
Instruments or Chattel Paper. If a Default or Event of Default shall have
occurred and be continuing, the Grantors, at their own expense, shall cause the
independent certified public accountants then engaged by Spacelabs Delaware to
prepare and deliver to the Lender at any time and from time to time promptly
upon the Lender's request the following reports with respect to Spacelabs
Delaware: (i) a reconciliation of all Accounts; (ii) an aging of all Accounts;
(iii) trial balances; and (iv) a test verification of such Accounts as the
Lender may request. The Grantors, at their own expense, shall deliver to the
Lender the results of each physical verification, if any, which the Grantors may
in their discretion have made, or caused any other Person to have made on their
behalf, of all or any portion of their Inventory.

        18. PATENT, TRADEMARK AND COPYRIGHT COLLATERAL.

            (a) The Grantors do not have any interest in, or title to, any
Patent (as defined in the Patent Collateral Assignment Agreement) or Trademark
(as defined in the Trademark Security Agreement) except as set forth in Schedule
III hereto. This Security Agreement is effective to create a valid and
continuing Lien on and, upon filing of the Patent Collateral Assignment
Agreement and Trademark Security Agreement with the United States Patent and
Trademark Office, the Register of Personal and Movable Real Rights (in the
Province of Quebec), and the Patent office and Trade Mark Office (in Ottawa,
Canada), perfected Liens in favor of the Lender on the Grantors' patents and
trademarks and such perfected Liens are enforceable as such as against any and
all creditors of and purchasers from the Grantors. Upon filing of the Patent
Collateral Assignment Agreement and Trademark Security Agreement with the United
States Patent and Trademark Office, the Register of Personal and Movable Real
Rights (in the Province of Quebec), and the Patent office and Trade Mark Office
(in Ottawa, Canada) and the filing of appropriate financing statements, all
action necessary or desirable to protect and perfect the Lender's Lien on the
Grantors' patents, trademarks or copyrights shall have been duly taken.

            (b) The Grantors shall notify the Lender immediately if they know or
have reason to know that any application or registration relating to any patent,
trademark or copyright (now or hereafter existing) may become abandoned or
dedicated, or of any final adverse determination (including the institution of,
or any such determination or development in, any proceeding in the United States
Patent and Trademark Office, the Register of Personal and Movable Real Rights
(in the Province of Quebec), and the Patent office and Trade Mark Office (in
Ottawa, Canada) or any court) regarding the Grantors' ownership of any patent,
trademark or copyright, its right to register the same, or to keep and maintain
the same.

            (c) In no event shall any Grantor, either directly or through any
agent, employee, licensee or designee, file an application for the registration
of any patent, trademark or copyright with the United States Patent and
Trademark Office, the Register of Personal and Movable Real Rights (in the
Province of Quebec), and the Canadian Intellectual Property Office (in Ottawa,
Canada), the United States Copyright Office or any similar office or agency
without giving the Lender prior written notice thereof, and, upon request of the
Lender, such Grantor shall execute and deliver any and all Patent Collateral
Assignment Agreements, Trademark Security Agreements or copyright security
agreements as Lender may reasonably request to evidence the Lender's Lien on
such patent, trademark or copyright, and the General Intangibles of Grantor
relating thereto or represented thereby.

                                      -13-

<PAGE>

            (d) The Grantors shall take all actions reasonably necessary or
requested by the Lender to maintain and pursue each application, to obtain the
relevant registration and to maintain the registration of each of the patents,
trademarks and copyrights (now or hereafter existing), including the filing of
applications for renewal, affidavits of use, affidavits of noncontestability,
and opposition and interference and cancellation proceedings, unless the
Grantors shall determine that such patent, trademark or copyright or the
opposition or interference therewith or cancellation thereof is not material to
the conduct of their businesses.

            (e) In the event that any of the patent, trademark or copyright
Collateral is infringed upon, or misappropriated or diluted by a third party,
the Grantors shall notify the Lender promptly after the Grantors learn thereof.
The Grantors shall, unless they shall reasonably determine that such patent,
trademark or copyright Collateral or the infringement, misappropriation or
dilution thereof, is not material to the conduct of their businesses or
operations, promptly sue for infringement, misappropriation or dilution and to
recover any and all damages for such infringement, misappropriation or dilution,
and shall take such other actions as the Lender shall deem appropriate under the
circumstances to protect such patent, trademark or copyright Collateral.

        19. INDEMNIFICATION. In any suit, proceeding or action reasonably
brought by the Lender relating to any Collateral for any sum owing with respect
thereto or to enforce any rights or claims with respect thereto, the Grantors
will save, indemnify and keep the Lender harmless from and against all
reasonable expense (including reasonable attorneys' fees and expenses), loss or
damage suffered by reason of any defense, setoff, counterclaim, recoupment or
reduction of liability whatsoever of the Account Debtor or other Person
obligated on the Collateral, arising out of a breach by the Grantors of any
obligation thereunder or arising out of any other agreement, indebtedness or
liability at any time owing to, or in favor of, such obligor or its successors
from the Grantors, except in the case of the Lender, to the extent such expense,
loss, or damage is attributable solely to the gross negligence or willful
misconduct of the Lender as finally determined by a court of competent
jurisdiction. All such obligations of the Grantors shall be and remain
enforceable against and only against the Grantors and shall not be enforceable
against the Lender.

        20. LIMITATION ON LIENS ON COLLATERAL. The Grantors will not create,
permit or suffer to exist, and will defend the Collateral against, and take such
other action as is necessary to remove, any Lien on the Collateral except
Permitted Liens and other liens expressly permitted in the Credit Agreement, and
will defend the right, title and interest of the Lender in and to any of the
Grantors' rights under the Collateral against the claims and demands of all
Persons whomsoever.

        21. NOTICE REGARDING COLLATERAL. The Grantors will advise Lender
promptly, in reasonable detail, (i) of any Lien (other than Permitted Liens and
other liens expressly permitted in the Credit Agreement) or claim made or
asserted against any of the Collateral, and (ii) of the occurrence of any other
event which would have a Material Adverse Effect.

        22. REMEDIES; RIGHTS UPON DEFAULT.

            (a) In addition to all other rights and remedies granted to it under
this Security Agreement, the Credit Agreement, the other Loan Documents and
under any other instrument or agreement securing, evidencing or relating to any
of the Obligations, if any Event of Default shall have occurred and be
continuing, the Lender may exercise all rights and remedies of a secured party
under the UCC. Without limiting the generality of the foregoing, the Grantors
expressly agree that in any such event the Lender, without demand of performance
or other demand, advertisement or notice of any kind (except the notice
specified below of time and place of public or private sale) to or upon the
Grantors or any other Person (all and each of which demands, advertisements and
notices are hereby expressly waived

                                      -14-

<PAGE>

to the maximum extent permitted by the UCC and other applicable law), may
forthwith enter upon the premises of the Grantors where any Collateral is
located through self-help, without judicial process, without first obtaining a
final judgment or giving the Grantors or any other Person notice and opportunity
for a hearing on Lender's claim or action and may collect, receive, assemble,
process, appropriate and realize upon the Collateral, or any part thereof, and
may forthwith sell, lease, license, assign, give an option or options to
purchase, or sell or otherwise dispose of and deliver said Collateral (or
contract to do so), or any part thereof, in one or more parcels at a public or
private sale or sales, at any exchange at such prices as it may deem acceptable,
for cash or on credit or for future delivery without assumption of any credit
risk. The Lender shall have the right upon any such public sale or sales and, to
the extent permitted by law, upon any such private sale or sales, to purchase
for the benefit of the Lender, the whole or any part of said Collateral so sold,
free of any right or equity of redemption, which equity of redemption the
Grantors hereby release. Such sales may be adjourned and continued from time to
time with or without notice. The Lender shall have the right to conduct such
sales on the Grantors' premises or elsewhere and shall have the right to use the
Grantors' premises without charge for such time or times as the Lender deems
reasonably necessary or advisable.

            (b) Upon the occurrence and during the continuation of an Event of
Default, the Grantors shall, (i) at the Lender's request , assemble the
Collateral and make it available to the Lender at a place or places designated
by the Lender which are reasonably convenient to the Lender and the Grantors,
whether at the Grantors' premises or elsewhere; (ii) until the Lender is able to
effect a sale, lease, or other disposition of Collateral, the Lender shall have
the right to hold or use Collateral, or any part thereof, to the extent that it
deems appropriate for the purpose of preserving Collateral or its value or for
any other purpose deemed appropriate by the Lender; (iii) the Lender shall have
no obligation to the Grantors to maintain or preserve the rights of the Grantors
as against third parties with respect to Collateral while Collateral is in the
possession of the Lender; (iv) the Lender may, if it so elects, seek the
appointment of a receiver or keeper to take possession of Collateral and to
enforce any of the Lender's remedies, with respect to such appointment without
prior notice or hearing as to such appointment; (v) the Lender shall apply the
net proceeds of any such collection, recovery, receipt, appropriation,
realization or sale to the Obligations as provided in the Credit Agreement, and
only after so paying over such net proceeds, and after the payment by the Lender
of any other amount required by any provision of law, need the Lender account
for the surplus, if any, to the Grantors; (vi) to the maximum extent permitted
by applicable law, the Grantors waive all claims, damages, and demands against
the Lender arising out of the repossession, retention or sale of the Collateral
except such as arise solely out of the gross negligence or willful misconduct of
the Lender as finally determined by a court of competent jurisdiction; (vii) the
Grantors agree that ten (10) days prior notice by the Lender of the time and
place of any public sale or of the time after which a private sale may take
place is reasonable notification of such matters; (viii) the Grantors shall
remain liable for any deficiency if the proceeds of any sale or disposition of
the Collateral are insufficient to pay all Obligations, including any reasonable
attorneys' fees or other reasonable expenses incurred by the Lender to collect
such deficiency.

            (c) Except as otherwise specifically provided herein, the Grantors
hereby waive presentment, demand, protest or any notice (to the maximum extent
permitted by applicable law) of any kind in connection with this Security
Agreement or any Collateral.

            (d) To the extent that applicable law imposes duties on the Lender
to exercise remedies in a commercially reasonable manner, the Grantors
acknowledge and agree that it is not commercially unreasonable for the Lender
(a) to fail to incur expenses reasonably deemed significant by the Lender to
prepare Collateral for disposition or otherwise to complete raw material or work
in process into finished goods or other finished products for disposition, (b)
to fail to obtain third party consents for access to Collateral to be disposed
of, or to obtain or, if not required by other law, to fail to obtain
governmental or third party consents for the collection or disposition of
Collateral to be collected or

                                      -15-

<PAGE>

disposed of, (c) to fail to exercise collection remedies against Account Debtors
or other Persons obligated on Collateral or to remove Liens on or any adverse
claims against Collateral, (d) to exercise collection remedies against Account
Debtors and other Persons obligated on Collateral directly or through the use of
collection agencies and other collection specialists, (e) to advertise
dispositions of Collateral through publications or media of general circulation,
whether or not the Collateral is of a specialized nature, (f) to contact other
Persons, whether or not in the same businesses as the Grantors, for expressions
of interest in acquiring all or any portion of such Collateral, (g) to hire one
or more professional auctioneers to assist in the disposition of Collateral,
whether or not the Collateral is of a specialized nature, (h) to dispose of
Collateral by utilizing internet sites that provide for the auction of assets of
the types included in the Collateral or that have the reasonable capacity of
doing so, or that match buyers and sellers of assets, (i) to dispose of assets
in wholesale rather than retail markets, (j) to disclaim disposition warranties,
such as title, possession or quiet enjoyment, (k) to purchase insurance or
credit enhancements to insure the Lender against risks of loss, collection or
disposition of Collateral or to provide to the Lender a guaranteed return from
the collection or disposition of Collateral, or (l) to the extent deemed
appropriate by the Lender, to obtain the services of other brokers, investment
bankers, consultants and other professionals to assist the Lender in the
collection or disposition of any of the Collateral. The Grantors acknowledge
that the purpose of this Section 22(d) is to provide non-exhaustive indications
of what actions or omissions by the Lender would not be commercially
unreasonable in the Lender's exercise of remedies against the Collateral and
that other actions or omissions by the Lender shall not be deemed commercially
unreasonable solely on account of not being indicated in this Section 22(d).
Without limitation upon the foregoing, nothing contained in this Section 22(d)
shall be construed to grant any rights to the Grantors or to impose any duties
on the Lender that would not have been granted or imposed by this Security
Agreement or by applicable law in the absence of this Section 22(d).

        23. GRANT OF LICENSE TO USE INTELLECTUAL PROPERTY. For the purpose of
enabling the Lender to exercise rights and remedies under Section 22 hereof
(including, without limiting the terms of Section 22 hereof, in order to take
possession of, hold, preserve, process, assemble, prepare for sale, market for
sale, sell or otherwise dispose of Collateral) at such time as the Lender shall
be lawfully entitled to exercise such rights and remedies, the Grantors hereby
grant to the Lender an irrevocable, nonexclusive license (exercisable without
payment of royalty or other compensation to the Grantors) to use, license or
sublicense any Intellectual Property now owned or hereafter acquired by the
Grantors, and wherever the same may be located, and including in such license
access to all media in which any of the licensed items may be recorded or stored
and to all computer software and programs used for the compilation or printout
thereof.

        24. LIMITATION ON LENDER'S DUTY IN RESPECT OF COLLATERAL. The Lender
shall use reasonable care with respect to the Collateral in its possession or
under its control. The Lender shall not have any other duty as to any Collateral
in its possession or control or in the possession or control of any agent or
nominee of the Lender, or any income thereon or as to the preservation of rights
against prior parties or any other rights pertaining thereto.

        25. PROVINCE OF QUEBEC PROVISIONS. Without limiting the generality of
the foregoing, with regard to the Collateral located in the Province of Quebec,
or over which the creation of security is governed by the laws of the Province
of Quebec, Guarantor hereby grants to the Lender, as security for its
obligations under the Guaranty, a first ranking movable hypothec under the Civil
Code of Quebec in the principal amount of Forty Million Canadian Dollars
(CDN$40,000,000) with interest thereon at the rate of twenty percent (20%) per
annum affecting the universality of all present and future rights, title and
interest of Guarantor in the Collateral, including without limitation all of the
movable property, present and future, corporeal or incorporeal, any proceeds of
insurance on movable property, and all contractual rights and undertaking of
Guarantor. Until written notice of the activation of a blocked account agreement
and a lockbox agreement is given by the Lender to Guarantor, which notice can be

                                      -16-

given by the Lender at any time (a) after and during the continuation of an
Event of Default, (b) that Availability, as defined in the Credit Agreement, is
less than $5,000,000, or (c) after the receipt of a request from the Borrowers
that more than the greater of (i) $750,000, and (ii) five percent (5%) of
Availability be attributable to the Borrowing Base from the Eligible Accounts
(and after an Inventory Activation Date, Eligible Inventory) owned by Guarantor,
the Lender hereby authorizes Guarantor to collect all debts, accounts
receivable, book debts, demands, judgments and other claims due, owing or
accruing to Guarantor. If, for the purpose of obtaining a judgment in any court,
it is necessary to convert the sum due to the Lender in any currency into
Canadian currency, Guarantor and the Lender agree, to the fullest extent that
they may effectively do so, that the rate of exchange used shall be that at
which, in accordance with normal banking procedure, such Lender could purchase
the original currency with the Canadian currency on the business day preceding
the day on which final judgment is given or if permitted by applicable law, on
the day on which the judgment is paid or satisfied.

        26. MISCELLANEOUS.

            (a) Reinstatement. This Security Agreement shall remain in full
force and effect and continue to be effective should any petition be filed by or
against any Grantor for liquidation or reorganization, should any Grantor become
insolvent or make an assignment for the benefit of any creditor or creditors or
should a receiver or trustee be appointed for all or any significant part of any
Grantor's assets, and shall continue to be effective or be reinstated, as the
case may be, if at any time payment and performance of the Obligations, or any
part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or
must otherwise be restored or returned by any obligee of the Obligations,
whether as a "voidable preference," "fraudulent conveyance," or otherwise, all
as though such payment or performance had not been made. In the event that any
payment, or any part thereof, is rescinded, reduced, restored or returned, the
Obligations shall be reinstated and deemed reduced only by such amount paid and
not so rescinded, reduced, restored or returned.

            (b) Notices. Except as otherwise provided herein, whenever it is
provided herein that any notice, demand, request, consent, approval, declaration
or other communication shall or may be given to or served upon any of the
parties by any other party, or whenever any of the parties desires to give and
serve upon any other party any communication with respect to this Security
Agreement, each such notice, demand, request, consent, approval, declaration or
other communication shall be in writing and shall be given in the manner, and
deemed received, as provided for in the Credit Agreement.

            (c) Severability. Whenever possible, each provision of this Security
Agreement shall be interpreted in a manner as to be effective and valid under
applicable law, but if any provision of this Security Agreement shall be
prohibited by or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity without invalidating
the remainder of such provision or the remaining provisions of this Security
Agreement. This Security Agreement is to be read, construed and applied together
with the Credit Agreement and the other Loan Documents which, taken together,
set forth the complete understanding and agreement of the Lender and the
Grantors with respect to the matters referred to herein and therein.

            (d) No Waiver; Cumulative Remedies. The Lender shall not by any act,
delay, omission or otherwise be deemed to have waived any of its rights or
remedies hereunder, and no waiver shall be valid unless in writing, signed by
the Lender and then only to the extent therein set forth. A waiver by the Lender
of any right or remedy hereunder on any one occasion shall not be construed as a
bar to any right or remedy which the Lender would otherwise have had on any
future occasion. No failure to exercise nor any delay in exercising on the part
of the Lender, any right, power or privilege

                                      -17-

<PAGE>

hereunder, shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege hereunder preclude any other or future
exercise thereof or the exercise of any other right, power or privilege. The
rights and remedies hereunder provided are cumulative and may be exercised
singly or concurrently, and are not exclusive of any rights and remedies
provided by law. None of the terms or provisions of this Security Agreement may
be waived, altered, modified or amended except by an instrument in writing, duly
executed by the Lender and the Grantors.

            (e) Limitation by Law. All rights, remedies and powers provided in
this Security Agreement may be exercised only to the extent that the exercise
thereof does not violate any applicable provision of law, and all the provisions
of this Security Agreement are intended to be subject to all applicable
mandatory provisions of law that may be controlling and to be limited to the
extent necessary so that they shall not render this Security Agreement invalid,
unenforceable, in whole or in part, or not entitled to be recorded, registered
or filed under the provisions of any applicable law.

            (f) Termination of this Security Agreement. Subject to Section 26(a)
hereof, this Security Agreement shall terminate upon the satisfactory
collateralization of all Letters of Credit and the payment in full of all other
Obligations (other than indemnification Obligations as to which no claim has
been asserted).

            (g) Successors and Assigns. This Security Agreement and all
obligations of the Grantors hereunder shall be binding upon the successors and
assigns of the Grantors (including any debtor-in-possession on behalf of any
Grantor) and shall, together with the rights and remedies of the Lender,
hereunder, inure to the benefit of the Lender, all future holders of any
instrument evidencing any of the Obligations and their respective successors and
assigns. No sales of participations, other sales, assignments, transfers or
other dispositions of any agreement governing or instrument evidencing the
Obligations or any portion thereof or interest therein shall in any manner
affect the Lien granted to the Lender hereunder. The Grantors may not assign,
sell, hypothecate or otherwise transfer any interest in or obligation under this
Security Agreement.

            (h) Counterparts. This Security Agreement may be authenticated in
any number of separate counterparts, each of which shall collectively and
separately constitute one and the same agreement. This Security Agreement may be
authenticated by manual signature, facsimile or, if approved in writing by the
Lender, electronic means, all of which shall be equally valid.

            (i) Governing Law; Choice of Forum; Service of Process.

                (a) WITH THE EXCEPTION OF THE MOVABLE HYPOTHEC GRANTED BY
GUARANTOR PURSUANT TO SECTION 25 HEREOF AND THE HYPOTHECARY RECOURSES ARISING
THEREFROM WHICH SHALL BE GOVERNED BY AND CONSTRUED ACCORDING TO THE LAWS OF THE
PROVINCE OF QUEBEC, THIS SECURITY AGREEMENT SHALL BE INTERPRETED AND THE RIGHTS
AND LIABILITIES OF THE PARTIES HERETO DETERMINED IN ACCORDANCE WITH THE INTERNAL
LAWS (AS OPPOSED TO THE CONFLICT OF LAWS PROVISIONS PROVIDED THAT PERFECTION
ISSUES WITH RESPECT TO ARTICLE 9 OF THE UCC MAY GIVE EFFECT TO APPLICABLE CHOICE
OR CONFLICT OF LAW RULES SET FORTH IN ARTICLE 9 OF THE UCC) OF THE STATE OF
WASHINGTON; PROVIDED THAT THE LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER
FEDERAL LAW.

                (b) SAVE AND EXCEPT FOR ANY HYPOTHECARY RECOURSE IN THE PROVINCE
OF QUEBEC AGAINST GUARANTOR WHICH SHALL BE UNDER THE JURISDICTION OF THE COURTS
OF THE PROVINCE OF QUEBEC, ANY LEGAL ACTION OR

                                      -18-

<PAGE>

PROCEEDING WITH RESPECT TO THIS SECURITY AGREEMENT OR ANY OTHER LOAN DOCUMENT
MAY BE BROUGHT IN THE COURTS OF THE STATE OF WASHINGTON OR OF THE UNITED STATES
OF AMERICA LOCATED IN KING COUNTY, WASHINGTON, AND BY EXECUTION AND DELIVERY OF
THIS SECURITY AGREEMENT, EACH OF THE GRANTORS AND THE LENDER CONSENTS, FOR
ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF
THOSE COURTS. EACH OF THE GRANTORS AND THE LENDER IRREVOCABLY WAIVES ANY
OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE
GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY ACTION OR PROCEEDING IN SUCH COURTS IN RESPECT OF THIS SECURITY
AGREEMENT OR ANY DOCUMENT RELATED HERETO. NOTWITHSTANDING THE FOREGOING: (1) THE
LENDER SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST THE
GRANTORS OR THEIR PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION THE LENDER
DEEMS NECESSARY OR APPROPRIATE IN ORDER TO REALIZE ON THE COLLATERAL OR OTHER
SECURITY FOR THE OBLIGATIONS AND (2) EACH OF THE PARTIES HERETO ACKNOWLEDGES
THAT ANY APPEALS FROM THE COURTS DESCRIBED IN THE IMMEDIATELY PRECEDING SENTENCE
MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE THOSE JURISDICTIONS.

                (c) THE GRANTORS HEREBY WAIVE PERSONAL SERVICE OF ANY AND ALL
PROCESS UPON THEM AND CONSENT THAT ALL SUCH SERVICE OF PROCESS MAY BE MADE BY
REGISTERED MAIL (RETURN RECEIPT REQUESTED) DIRECTED TO THE GRANTORS AT THEIR
ADDRESSES SET FORTH IN SECTION 12.8 OF THE CREDIT AGREEMENT AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED FIVE (5) DAYS AFTER THE SAME SHALL HAVE BEEN SO
DEPOSITED IN THE U.S. MAIL POSTAGE PREPAID. NOTHING CONTAINED HEREIN SHALL
AFFECT THE RIGHT OF THE LENDER TO SERVE LEGAL PROCESS BY ANY OTHER MANNER
PERMITTED BY LAW.

            (j) Waiver of Jury Trial. GRANTORS AND THE LENDER EACH IRREVOCABLY
WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING OUT OF OR RELATED TO THIS SECURITY AGREEMENT, THE OTHER
LOAN DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN ANY
ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES
AGAINST ANY OTHER PARTY OR ANY LENDER-RELATED PERSON OR PARTICIPANT, WHETHER
WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE. THE GRANTORS AND THE
LENDER EACH AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A
COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER
AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF
THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN
WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THE CREDIT
AGREEMENT, THIS SECURITY AGREEMENT OR THE OTHER LOAN DOCUMENTS OR ANY PROVISION
HEREOF OR THEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS,
RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THE CREDIT AGREEMENT, THIS SECURITY
AGREEMENT AND THE OTHER LOAN DOCUMENTS.

            (k) Section Titles. The Section titles contained in this Security
Agreement are and shall be without substantive meaning or content of any kind
whatsoever and are not a part of the agreement between the parties hereto.

jointly in the negotiation and drafting of this Security Agreement. In the event
an ambiguity or question of intent or interpretation arises, this Security
Agreement shall be construed as if drafted jointly by the parties hereto and no
presumption or burden of proof shall arise favoring or disfavoring any party by
virtue of the authorship of any provisions of this Security Agreement.

            (m) Advice of Counsel. Each of the parties represents to each other
party hereto that it has discussed this Security Agreement and, specifically,
the provisions of Section 26(i) and Section 26(j), with its counsel.

shall be for the benefit of the Lender, and all proceeds or payments realized
