4. PER SHARE DATA

In accordance with Statement of Financial Accounting Standards (FAS) No. 128,
Earnings Per Share, the Company has reported both basic and diluted net income
per common share for each period presented. Basic earnings per share (EPS) is
calculated based on the weighted average number of common shares outstanding
during the period. The computation of diluted EPS includes the effect of all
dilutive potential common shares outstanding. Conversion of dilutive potential
common shares is assumed based on the average market price of common shares
outstanding during the period. All previously reported EPS have been restated to
conform with the provisions of FAS 128.

The schedules below represent a reconciliation of the numerators and
denominators of the basic and diluted EPS calculations for the second quarter of
1998 and 1997 as well as year-to-date (YTD) 1998 and 1997.

5. COMPREHENSIVE INCOME

In June 1997, the Financial Accounting Standards Board issued FAS No. 130,
Reporting Comprehensive Income, which became effective for fiscal years
beginning after December 15, 1997. FAS 130 requires that an entity report an
amount representing total comprehensive income in condensed financial statements
of interim periods issued to Company shareholders. Reclassification of financial
statements for earlier periods provided for comparative purposes is required.

Comprehensive income represents the change in equity of a business enterprise
during a period from transactions and other events and circumstances from
non-owner sources and includes net income as well as items referred to as other
comprehensive income or loss. For the periods presented, the only item of other
comprehensive loss for the Company is the foreign currency translation
adjustment resulting from the consolidation of foreign operations. The table
below provides a reconciliation of net income to total comprehensive income for
each period presented.

7.  Distribution

On February 2, 1998, the Company approved a plan to spin-off its handheld
business division as an independent, publicly owned company (SonoSight, Inc.) to
its shareholders. A registration statement on Form 10 was filed with the
Securities and Exchange Commission in the name of SonoSight, Inc. and became
effective on April 2, 1998. The spin-off was effected through a tax-free
distribution of SonoSight shares to ATL shareholders on April 6, 1998 (the
"Distribution"). The Company's shareholders received one share of SonoSight
common stock for each three shares of the Company's common stock held. In
connection with the Distribution, the Company contributed to SonoSight
additional funding of $18,000 in cash on the Distribution date and will
contribute $12,000 in cash in January 1999. The Company and SonoSight have
entered into a number of agreements to facilitate the Distribution and the
transition of the company to an independent business.

Handheld business division spending totaled approximately $1,200 for the three
month period ended June 27, 1997. The EPS impact of the handheld business net
operating expenses was approximately $0.07 in the second quarter of 1997. There
was no handheld spending during the second quarter of 1998. Handheld business
division spending totaled approximately $2,500 and $2,200, respectively, for the
six month periods ended July 3, 1998 and June 27, 1997. The EPS impact of the
handheld business net operating expenses was approximately $0.13 and $0.12,
respectively, for the first half of 1998 and 1997. In connection with the
Distribution, the Company incurred stock distribution expenses of approximately
$1,300 in the first quarter of 1998. The EPS impact of the stock distribution
expenses was approximately $0.07 for the first six months of 1998.

8.  Subsequent Event

On July 29, 1998, Royal Philips Electronics (Philips) of the Netherlands and the
Company announced the signing of an Agreement and Plan of Merger for Philips to
acquire all of the outstanding shares of the Company for approximately $800,000
or $50.50 per share for each outstanding share of the Company's common stock.
The transaction will be a cash tender offer followed by a cash merger to acquire
any shares not previously tendered. As a result of the transaction, the Company
will become a wholly owned subsidiary of Philips.

The Company's Board of Directors unanimously approved the transaction. Philips
commenced its cash tender offer on August 4, 1998. The cash tender offer is
subject to Philips receiving at least a majority of the fully diluted shares of
the Company as well as the receipt of customary regulatory approvals. Completion
of the transaction is expected in September 1998 provided the above conditions
are met.

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

</TABLE> 

The Company reported net income of $5.5 million or $0.35 per share in the second
quarter of 1998 compared with net income of $2.5 million or $0.17 per share in
the second quarter of 1997. For the first six months, the Company reported net
income of $7.6 million or $0.50 per share in 1998 compared with net income of
$4.6 million or $0.31 per share in 1997. The impact on YTD net income and net
income per share from the SonoSight, Inc. stock distribution expenses incurred
during the first quarter of 1998 was approximately $1.0 million and $0.07 per
share, respectively. All per share amounts are stated on a diluted basis.

REVENUES AND GROSS PROFIT
- -------------------------
The Company's worldwide revenues increased 10.8% to $111.7 million in the second
quarter of 1998 compared with $100.8 million in the second quarter of 1997. The
majority of this growth can be attributed to product sales which increased by
$10.5 million or 13.4% in the second quarter of 1998 compared to the same period
in the prior year. The increase in product sales reflects strong worldwide
demand for the Company's HDI(R) 5000 and HDI 3000 systems, partially offset by
the foreign exchange impact of the stronger U.S. dollar on international
business and the sale of the Company's image management business in the second
quarter of 1997. Service revenues approximated amounts reported in the same
period of 1997. For the first six months of 1998, worldwide revenues increased
8.1% to $217.1 million compared with $200.9 million in the prior year for the
reasons noted above.

Gross profit was $56.4 million in the second quarter of 1998, an increase of
$7.0 million compared with gross profit of $49.4 million in the same quarter of
the prior year. Total gross margin for the second quarter of 1998 increased to
50.5% compared with 49.0% in the prior year. The improvement in gross margin
reflects the favorable shift in product mix to the Company's higher margin HDI
products. Gross profit rose on higher unit volumes of both the HDI 5000 and HDI
3000, partially offset by the impact of a stronger U.S. dollar on international
business and the sale of the Company's image management business. For the first
six months of 1998, gross profit was $109.2 million compared to $97.2 million
for the same period of 1997. YTD gross margin increased to 50.3% from 48.4% in
1997 for the reasons noted above.

OPERATING EXPENSES, NET
- -----------------------
Operating expenses increased to $49.8 million in the second quarter of 1998 from
$46.5 million in the same period of 1997. Selling, general and administrative
expenses were $35.3 million, an increase of 12.8% over the second quarter of
1997. The increase in selling, general, and administrative expenses reflects
higher sales volumes over the prior year and increased market development
expenditures in Asia and Latin America. These increases were partially offset by
the spin-off of SonoSight in April 1998, favorable impacts of foreign exchange
and the sale of the Company's image management business in 1997. Research and
development (R&D) expenses decreased 7.8% to $14.0 million in the second quarter
of 1998 compared with $15.2 million in the second quarter of 1997. The decrease
in R&D expenses is primarily due to the spin-off of SonoSight and the sale of
the Company's image management business as discussed above. Handheld business
division spending totaled approximately $1.2 million for the three month period
ended June 27, 1997. The EPS impact of the handheld business net operating
expenses was approximately $0.07 in the second quarter of 1997. There was no
handheld spending during the second quarter of 1998.

For the first six months of 1998, operating expenses increased to $100.0 million
or 46.1% of total revenues compared to $92.0 million or 45.8% of total revenues
in 1997. This increase is primarily due to one-time stock distribution expenses
of approximately $1.3 million incurred during the first quarter of 1998 for the
spin-off of SonoSight as well as the factors noted above. Handheld business
division spending totaled approximately $2.5 million and $2.2 million,
respectively, for the six month periods ended July 3, 1998 and June 27, 1997.
The EPS impact of the handheld business net operating expenses was approximately
$0.13 and $0.12, respectively, for the first half of 1998 and 1997.

INTEREST INCOME AND EXPENSE
- ---------------------------
The Company earned net interest income of $0.1 million during the second quarter
of 1998 compared with net interest income of $0.3 million during the same period
in 1997. Net interest income includes interest income earned on cash balances
available for investment, extended term receivables and leasing activity, offset
by interest expense on long-term debt. 1997 interest expense also includes
post-judgment interest expense accrued on patent litigation damages which were
fully paid in the fourth quarter of 1997.

TAXES AND NET INCOME
- --------------------
For the second quarter of 1998, the Company reported an income tax expense of
$1.3 million, which represents a 19.2% effective tax rate for U.S. federal,
state and foreign income. For the second quarter of 1997, the Company reported
income tax expense of $0.6 million which represents a 20% effective tax rate for
U.S. federal, state and foreign income.

</TABLE> 

Cash and cash equivalents totaled $46.4 million at July 3, 1998 compared with
$30.8 million at December 31, 1997. As shown in the Condensed Consolidated
Statement of Cash Flows, during the first six months of 1998, the Company
generated $29.2 million from operating activities while financing activities
provided cash of $1.7 million. At July 3, 1998, receivables, net, decreased
$18.7 million and accounts payable and accrued expenses decreased $14.4 million
from December 31, 1997 reflecting seasonally high activity levels in the fourth
quarter of 1997. During the second quarter of 1998, the Company borrowed
approximately $17 million to finance the construction of a new building on its
corporate campus and contributed $18 million of cash to SonoSight in connection
with the spin-off (see detailed discussion of items below). In addition, $4.1
million was generated from the exercise of employee stock options during the
first six months of 1998.

The Company began to take occupancy of the new 101,000 square foot building on
its corporate campus in July 1998. The building has an estimated completion cost
of approximately $15 to $16 million. Initial funding for the project came from
working capital with the transition to long-term debt in the second quarter of
1998.

The Company spun-off its handheld business on April 6, 1998 (the
"Distribution"). In connection with the spin-off, the Company contributed
capital of $18 million in cash on the Distribution date and will contribute an
additional $12 million in cash in January 1999 (see Note 7 to the Condensed
Consolidated Financial Statements, Distribution).

The Company repurchased 16,700 shares of its own common stock in the open market
for $0.7 million during the second quarter of 1998 under repurchase programs
intended to service the Company's benefit programs. The Company repurchased
5,000 shares totaling $0.2 million during the first quarter of 1998 and 343,000
shares totaling $11.9 million in 1997. In May 1997, the Board of Directors
authorized the Company to purchase up to 1,000,000 shares of its common stock,
subject to certain criteria.

Item 2.    Management's Discussion and Analysis of Financial Condition and 
           ---------------------------------------------------------------
           Results of Operations
           ---------------------
             (Continued)

In addition to its cash balances, the Company has available domestic credit
facilities of $35 million, including a committed line of credit of $25 million.
Barring any unforeseen circumstances or events, management expects existing
cash, available credit lines and funds from operations to be sufficient to meet
the Company's operating requirements for 1998 (see Forward Looking Information).

FORWARD LOOKING INFORMATION
- ---------------------------
As an update to the forward looking information provided in the Company's 1997
Annual Report to Shareholders and the Form 10-Q filing for the first quarter of
1998, the Company provides the following information.

The Company reiterates the guidance provided at the end of the first quarter of
1998 that it is targeting earnings for the 1998 fiscal year to be in the range
of approximately $2.35 per share.

Certain statements in this report relating to the sufficiency of credit lines
and funds from operations, the tender offer and consummation and success of the
merger, and anticipated financial results for the balance of 1998 are forward
looking statements which involve a number of risks and uncertainties which could
cause actual results to differ materially from those anticipated in the forward
looking statements. Among the ongoing factors that could cause actual results to
differ materially from the above are the following considerations. Growth in the
ultrasound market in Europe remains slow and certain Asian markets are troubled
by turbulent economic conditions, which may cause revenue growth to fall short
of expectations. Worldwide competition in the ultrasound market continues at an
intense level, and the Company may lose sales to other product offerings. These
factors may adversely impact the Company's sales volume or selling prices or
both. Unanticipated events, such as delays in the Company's product development
and cost reduction programs, the unavailability of components critical to the
Company's products due to natural disasters, changes in vendor businesses or
otherwise, economic instability in Asian and other markets, the stronger U.S.
dollar, delays in receiving necessary regulatory approvals, or other unforeseen
events could adversely impact the Company's financial results for 1998. The
factors which may impede the merger and its outcome include securing all
necessary governmental and other approvals, the satisfaction of all conditions
to the merger, changing business or other market conditions, and the success of
the business combination as planned by the parties. If the merger is not
completed the Company will nonetheless bear significant legal, investment
banking, and other costs attendant to preparation for the merger, and the price
of the Company's stock can become volatile. These and other factors could
adversely affect the outcome and financial effects of the plans and events
described herein.

On July 29, 1998, Royal Philips Electronics (Philips) of the Netherlands and the
Company announced the signing of an Agreement and Plan of Merger for Philips to
acquire all of the outstanding shares of the Company for approximately $800,000
or $50.50 per share for each outstanding share of the Company's common stock.
The transaction will be a cash tender offer followed by a cash merger to acquire
any shares not previously tendered. As a result of the transaction, the Company
will become a wholly owned subsidiary of Philips.

The Company's Board of Directors unanimously approved the transaction. Philips
commenced its cash tender offer on August 4, 1998. The cash tender offer is
subject to Philips receiving at least a majority of the fully diluted shares of
the Company as well as the receipt of customary regulatory approvals. Completion
of the transaction is expected in September 1998 provided the above conditions
are met.

      ----------                                                               
Interest Period, an interest rate per annum equal to the sum of (a) the
applicable Usage Factor and (b) the product of (i) the Euro-dollar Rate in
effect for such Applicable Interest Period and (ii) the Euro-dollar Reserves in
effect on the first day of such Applicable Interest Period.

          The "Euro-dollar Rate" will be determined on the basis of the offered
     rate for deposits in U.S. Dollars for the Applicable Interest Period
     commencing on the first day of such Applicable Interest Period (the "Reset
     Date") which appears on the display designated as the "LIBO" page in the
     Reuters Monitor Money Rates Service (or such other page as may replace the
     LIBO page on that service for the purpose of displaying London interbank
     offered rates of major banks; or such other financial news service provider
     to which Lender and Borrower mutually agree) as of 11:00 o'clock a.m.,
     London time, on the day that is two Business Days preceding the Reset Date.
     If at least two such offered rates appear on such Reuters screen LIBO page,
     the Euro-dollar Rate in respect of that Reset Date will be the arithmetic
     mean of such offered rates.  If fewer than two offered rates appear, the
     Euro-dollar Rate will be determined on the basis of the rates at which
     deposits in U.S. Dollars are offered by four major banks (selected by
     Lender) in the London interbank market at approximately 11:00 o'clock a.m.,
     London time, on the day that is two Business Days preceding the Reset Date
     to prime banks in the London interbank market for the Applicable Interest
     Period.  The Lender will request the principal London office of each of the
     four banks to provide a quotation of its rate.  If at least two such
     quotations are provided, the Euro-dollar Rate will be the arithmetic mean
     of the quotations.  If fewer than two quotations are provided as requested,
     the Euro-dollar Rate in respect of that Reset Date will be the arithmetic
     mean of the rates quoted by major banks in New York City (selected by the
     Lender) at approximately 11:00 o'clock a.m., New York city time, on that
     Reset Date for loans in U.S. Dollars in an amount equal to the applicable
     Loan to leading banks in Europe for the Applicable Interest Period.

          As used herein, the term "Euro-dollar Reserves" means a fraction
     (expressed as a decimal), the numerator of which is the number one and the
     denominator of which is the number one minus the aggregate of the maximum
     reserve percentages (including, without limitation, any special,
     supplemental, marginal or emergency reserves) expressed as a decimal
     established by the Board of Governors of the Federal Reserve System or any
     other banking authority to which the Lenders are subject for Eurocurrency
     Liability (as defined in Regulation D of such Board of Governors).  It is
     agreed that for purposes hereof, each Loan shall be deemed to constitute a
     Eurocurrency Liability and to be subject to the reserve requirements of
     Regulation D, without benefit of credit or proration, exemptions or offsets
     which might otherwise be available to the Lenders from time to time under
     such Regulation D.  Each LIBOR Rate shall be adjusted automatically on and
     as of the effective date of any change in the Euro-dollar Reserves.

     "Lien" means, for any person, any security interest, pledge, mortgage,

delinquent or which remain payable without penalty or the validity or amount of
which is being contested in good faith by appropriate proceedings upon stay of
execution of the enforcement thereof; (ii) liens imposed by law (such as
mechanics' liens) incurred in good faith in the ordinary course of business
which are not delinquent or which remain payable without penalty or the validity
or amount of which is being contested in good faith by appropriate proceedings
upon stay of execution of the enforcement thereof; and (iii) deposits or pledges
under worker's compensation, unemployment insurance, social security or other
similar laws or made to secure the performance of bids, tenders, contracts
(except for repayment of borrowed money), or leases, or to secure statutory

amount less than the outstanding principal balance of the Loans plus the U.S.
Dollar equivalent of the outstanding principal balance of all Multicurrency
Advances.

     Section 2.4  Repayment of Principal.  The Borrower shall repay to the
                  ----------------------                                  
Lender the principal amount of each Loan on the Maturity Date.

     Section 2.5  Interest on Loans.
                  ----------------- 

          (a)     Interest Rate.  The Borrower agrees to pay to Lender interest
                  -------------
     on the unpaid principal amount of each Loan from the date of such Loan
     until such Loan shall be due and payable at a per annum rate equal to the
     Applicable Interest Rate, and, if default shall occur in the payment when
     due of any such Loan, from the maturity of that Loan until it is paid in
     full at a per annum rate equal to two percentage points (2%) above the
     Reference Rate (changing as the Reference Rate changes).

          (b)     Interest Payment Dates.  Accrued but unpaid interest on each
                  ----------------------
     Fixed Rate Loan shall be paid on the last day of each Applicable Interest
     Period, on the date of any principal payment (to the extent accrued on the
     principal amount paid), and at maturity and, in the case of a LIBOR Loan
     for which the Applicable Interest Period is six months, on the day that is
     three months after the commencement of such Applicable Interest Period.
     Accrued but unpaid interest on each Reference Rate Loan shall be paid on
     the last Business Day of each calendar quarter commencing

                                       7
<PAGE>
 
     on June 30, 1997, and continuing on the last Business Day of each March,
     June, September and December thereafter and on the date of any principal
     payment (to the extent accrued on the principal amount paid) and at
     maturity. Unpaid interest accruing on amounts in default shall be payable
     on demand.

          (c) Adjustments in Interest Rate Resulting from Usage Factor Changes.
              ----------------------------------------------------------------  
     During any calendar quarter, interest shall initially accrue and be paid on
     LIBOR Loans based on the Usage Factor that would apply if, during such
     calendar quarter, the average daily outstanding balance of Loans was less
     than $7,500,000 (the "Preliminary Usage Factor").  The interest as so
     accrued and paid shall be subject to adjustment as provided in this Section
     at the end of the calendar quarter for the actual Usage Factor for such
     quarter.  At the end of each calendar quarter, Lender shall determine the
     actual daily outstanding balance of Loans during the preceding calendar
     quarter and the correspondingly appropriate Usage Factor to be used in
     determining the actual interest rate for each LIBOR Loan outstanding during
     such calendar quarter (the "Actual Usage Factor").  The Lender shall
     calculate the adjustments to be made in interest accruing or paid on each
     LIBOR Loan resulting from the difference between the Actual Usage Factor
     and the Preliminary Usage Factor and shall so notify the Borrower.  To the
     extent that such adjustment relates to LIBOR Loans for which interest was
     previously paid in such calendar quarter, Borrower's demand deposit account
     with Lender shall be debited for the amount of such adjustment on the day
     following such notice (and Borrower shall assure that there are  available
     funds in such account to permit such withdrawal).  To the extent the
     adjustment relates to LIBOR Loans for which interest has accrued during
     such calendar quarter but not been paid, the interest, as adjusted, shall
     be paid on the dates scheduled for interest payment pursuant to Section
     2.5(d).

          (d) Selection of Alternative Rates.
              ------------------------------ 

              (i)     The Borrower may, subject to the requirements of this
          Section 2.5(d), on same-day notice (in the case of a selection of
          Reference Rate or Quoted Rate) or three (3) Business Days' prior
          notice (in the case of a selection of a LIBOR Rate) elect to have
          interest accrue on any Loan or any portion thereof at a Fixed Rate for
          an Applicable Interest Period. Such notice (herein, an "Interest Rate
          Notice") shall be deemed delivered on receipt by Lender except that
          the Interest Rate Notice received by the Lender after 10:00 a.m.,
          (Seattle time), on any Business Day, shall be deemed to be received on
          the immediately succeeding Business Day. An Interest Rate Notice may
          be given in writing or telephonically (but, if given telephonically,
          shall be confirmed in writing prior to 12:00 noon (Seattle time) on
          the first day of the Applicable Interest Period). Such Interest Rate
          Notice shall identify, subject to the conditions of this Section
          2.5(d), the Loan or portions thereof, the Fixed Rate and the
          Applicable Interest Period which the Borrower selects. Any such
          Interest Rate Notice shall be irrevocable and shall constitute a
          representation and warranty by the Borrower that as of the date of
          such Interest Rate Notice no Event of Default or Default has occurred
          and is continuing.

              (ii)    Borrower's right to select a Fixed Rate to apply to a Loan
          or any portion thereof shall be subject to the following conditions:
          (i) the aggregate of all Loans or portions thereof to accrue interest
          at a particular LIBOR Rate for the same Applicable Interest Period
          shall be an integral multiple of Five Hundred Thousand Dollars
          ($500,000); (ii) the Quoted Rate may not be selected for any Loan or
          portion thereof which is less than Five Million Dollars ($5,000,000);
          (iii) a Fixed Rate may not be selected for any Loan or portion thereof
          which is already accruing interest at a Fixed Rate unless such
          selection is only to become effective at the maturity of the
          Applicable Interest Period then in effect; (iv) the Lender shall not
          have given notice pursuant to Section 2.5(f) that the selected LIBOR
          Rate is not available on or before the day the Borrower gave the
          Interest Rate Notice; and (v) no Default or Event of Default shall
          have occurred and be continuing.

              (iii)   In the absence of an effective request for the application
          of a Fixed Rate, the Loans or remaining portions thereof shall accrue
          interest at the Reference Rate.

                                       8

               (iv)  The Interest Rate Notice may be given with and contained in
          any Notice of Borrowing.

               (v)   If the Borrower delivers an Interest Rate Notice and a
          condition precedent to the making of the applicable Loan set forth in
          Article 5 or the conversion to the requested interest rate set forth
          in this section 2.5 is not satisfied or waived in writing by Lender,
          Borrower shall indemnify the Lender for all losses and any costs which
          the Lender sustains as a consequence thereof including, without
          limitation, the costs of re-employment of funds at rates lower than
          the cost to the Lender of such funds.  A certificate of the Lender
          setting forth the amount due to it pursuant to this subparagraph (v)
          and the basis for, and the calculation of, such amount shall be prima
          facie evidence of the amount due to it hereunder, absent manifest
          error.  Payment of the amount owed shall be due within fifteen (15)
          days after the Borrower's receipt of such certificate.

          (e)  Applicable Days For Computation of Interest.  Computations of
               -------------------------------------------                  
     interest shall be made on the basis of a year of three hundred sixty days
     (360), in each case, for the actual number of days (including the first day
     but excluding the last day) occurring in the period for which such interest
     is payable.

          (f)  Unavailable LIBOR Rate.  If Lender determines that for any reason
               ----------------------                                           
     beyond Lender's control fair and adequate means do not exist for
     establishing a particular LIBOR Rate or that a specific LIBOR Rate will not
     adequately and fairly reflect the cost to it of making or maintaining the
     principal amount of a particular LIBOR Loan or that accruing interest on
     any Loan at a LIBOR Rate by Lender has become unlawful, Lender may give
     notice of that fact to the Borrower and such determination shall be
     conclusive and binding absent manifest error.  After such notice has been
     given and until Lender notifies the Borrower that the circumstances giving
     rise to such notice no longer exist, the interest rate or rates so
     identified in such notice shall no longer be available.  If,
     notwithstanding such notice, Borrower shall thereafter select a LIBOR Rate,
     the Lender shall promptly notify the Borrower again that a LIBOR Rate is
     unavailable.  Thereafter, any subsequent request by the Borrower to have
     interest accrue at a LIBOR Rate shall be deemed to be a request for
     interest to accrue at the Reference Rate.  If the circumstances giving rise
     to the notice described herein no longer exist, the Lender shall notify the
     Borrower in writing of that fact, and the Borrower shall then once again
     become entitled to request that a LIBOR Rate apply to the Loans in
     accordance with Section 2.5(d) hereof.

          (g)  Compensation for Increased Costs.  In the event that after the
               --------------------------------                              
     date hereof any change occurs in any applicable law, regulation, treaty or
     directive or interpretation thereof by any authority charged with the
     administration or interpretation thereof, or any condition is imposed by
     any authority after the date hereof or any change occurs in any condition
     imposed by any authority on or prior to the date hereof which:

               (i)    subjects Lender to any Tax, or changes the basis of
          taxation of any payments to Lender on account of principal of or
          interest on the Fixed Rate Loans, the Revolving Note (to the extent
          the Revolving Note evidences Fixed Rate Loans) or fees in respect of
          Lender's obligation to make Fixed Rate Loans or other amounts payable
          with respect to its Fixed Rate Loans (other than a change in the rate
          of tax based solely on the overall net or gross income of Lender); or

               (ii)   imposes, modifies or determines applicable any reserve,
          deposit or similar requirements against any assets held by, deposits
          with or for the account of, or loans or commitments by, any office of
          Lender in connection with its Fixed Rate Loans to the extent the
          amount of which is in excess of, or was not applicable at the time of
          computation of, the amounts provided for in the definition of the
          applicable Fixed Rate; or

               (iii)   affects the amount of capital required or expected to be
          maintained by

                                       9
<PAGE>
 
          banks generally or corporations controlling banks and Lender
          determines the amount by which Lender or any corporation controlling
          Lender is required or expected to maintain or increase its capital is
          increased by, or based upon, the existence of this Agreement or the
          Loans or the Commitment hereunder;

               (iv)   imposes upon Lender any other condition with respect to
          the Fixed Rate Loans or the obligation to make Fixed Rate Loans;

     which, as a result thereof, (1) increases the cost to Lender of making or
     maintaining the Loans or its commitment hereunder, or (2) reduces the net
     amount of any payment received by Lender in respect of its Fixed Rate Loans
     (whether of principal, interest, commitment fees or otherwise), or (3)
     requires Lender to make any payment on or calculated by reference to the
     gross amount of any sum received by it in respect of its Fixed Rate Loans,
     then and in any such case Lender shall, as soon as reasonably practical
     after becoming aware of such event, notify Borrower thereof, and, the
     Borrower shall pay to Lender on demand such amount or amounts as will
     compensate Lender for any such increased cost, deduction or payment
     actually incurred or made by Lender.  The demand for payment by Lender
     shall be delivered to the Borrower and shall state the subjection or change
     which occurred or the reserve or deposit requirements or other conditions
     which have been imposed upon Lender or the request, direction or
     requirement with which it has complied, together with the date thereof, the
     amount of such cost, reduction or payment and the manner in which such
     amount has been calculated.  The statement of Lender as to the additional
     amounts payable pursuant to this Section 2.5(g) shall be prima facie
     evidence of the amounts due hereunder, unless manifest error.

     The protection of this Section 2.5(g) shall be available to Lender
     regardless of any possible contention of invalidity or inapplicability of
     the relevant law, regulation, treaty, directive, condition or
     interpretation thereof.  In the event that the Borrower pays Lender the
     amount necessary to compensate Lender for any charge, deduction or payment
     incurred or made by Lender as provided in this Section 2.5(g), and such
     charge, deduction or payment or any part thereof is subsequently returned
     to Lender as a result of the final determination of the invalidity or
     inapplicability of the relevant law, regulation, treaty, directive or
     condition, then Lender shall remit to the Borrower the amount paid by the
     Borrower which has actually been returned to Lender (together with any
     interest actually paid to Lender on such returned amount), less the
     percentage share of Lender's costs and expenses incurred in connection with
     such governmental regulation or any challenge made by Lender with respect
     to its validity or applicability that is proportionate to the percentage
     that the affected Loan or Commitment bears to all of Lender's affected
     assets.

     Section 2.6  Prepayments.  Reference Rate Loans may be repaid at any time
                  -----------                                                 
without penalty or premium.  Quoted Rate Loans may not be voluntarily repaid
prior to the end of the Applicable Interest Period.  LIBOR Loans may be repaid
prior to the end of the Applicable Interest Period.  A fee computed in the
manner set out in Schedule 1 shall be assessed and paid at the time of such
early repayment of a LIBOR Loan or refinancing.  Such fee shall apply in all
circumstances where a LIBOR Loan is paid prior to the end of the Applicable
Interest Period, regardless of whether such payment is voluntary, mandatory or
the result of the Lender's collection efforts.

     Section 2.7  Revolving Note.  The Loans shall be evidenced by a promissory
                  --------------                                               
note of the Borrower substantially in the form of Exhibit A hereto, payable to
the order of Lender, dated as of the date hereof, and in the face amount of the
Commitment (the "Revolving Note").  Lender is hereby authorized to record the
date and amount of Loans it makes and the date and amount of each payment of
principal and interest thereon on a schedule or computer-generated statement
constituting part of its Revolving Note; provided, however, that the failure to
                                         --------  -------                     
make any such recordation or any error in any such recordation shall not affect
the obligations of the Borrower hereunder or under the Revolving Note.

     Section 2.8    Manner of Payments.
                    ------------------ 

          (a)       All payments and prepayments of principal and interest on
     any Loan or Multicurrency Advance and all other amounts payable hereunder
     by the Borrower or Guarantor to Lender shall be made by paying the same in
     United States Dollars or the currency that was advanced and in immediately
     available funds to the Lender at its Commercial Loan Service Center,
     Seattle, Washington not later than 10:00 o'clock a.m., Seattle time, on the
     date on which such payment or prepayment shall become due. If such payment
     is received after 10:00 o'clock a.m., then it will be deemed received on
     the next Business Day.

          (b)       The Borrower and Guarantor hereby authorize the Lender, if
     and to the extent any payment is not promptly made pursuant to this
     Agreement or any other Loan Document, to charge from time to time against
     any or all of the accounts of the Borrower or Guarantor with the Lender.

          (c)       Whenever any payment hereunder or under any other Loan
     Document shall be stated to be due or whenever the last day of any interest
     period would otherwise occur on a day other than a Business Day, such
     payment shall be made and the last day of such interest period shall occur
     on the next succeeding Business Day and such extension of time shall in
     such case be included in the computation and payment of interest or
     commitment fees, as the case may be, unless such extension would cause such
     payment to be made or the last day of such interest period to occur in the
     next following calendar month, in which case such payment shall be due and
     the last day of such interest period shall occur on the next preceding
     Business Day.

     Section 2.9    Commitment Fees.  During the Commitment Period, Borrower
                    ---------------                                         
agrees to pay to the Lender a commitment fee computed daily at the rate of one-
fourth of one percent (1/4%) per annum on the difference between the Commitment
and the combined outstanding principal balance of the Loans and Multicurrency
Advances (based on U.S. Dollar equivalent determined on the date of funding such
Multicurrency Advance) payable in arrears at quarterly intervals commencing on
June 30, 1997, and payable on the last Business Day of each March, June,
September and December thereafter, except that accrued commitment fees shall be
payable on the Maturity Date and on demand after Default.  Computations of
commitment fees shall be made on the basis of a year of three hundred sixty
(360) days for the actual number of days (including the first day but excluding
the last day) occurring in the period for which such fees are payable.

     Section 2.10   Extension of Maturity Date.  The Borrower may request that
                    --------------------------                                
Lender extend the Maturity Date for successive one-year periods by notifying the
Lender in writing at any time before a date one (1) year prior to the then-
existing Maturity Date.  If Lender consents in writing to such an extension
within sixty (60) days of such request, the Maturity Date shall be extended for
one (1) additional year.

determined on the date the interest rate for such Multicurrency Advance is
determined, by delivering its borrowing notice to Lender in the form of Exhibit
C attached ("Multicurrency Borrowing Notice"), on or before 9:30 a.m., Seattle
time, on a London Banking Day at least three Business Days prior to the date the
Multicurrency Advance is to be made.  Such notice shall specify the currency,
principal amount, and Applicable Interest Period requested.  Each Multicurrency
Advance shall be in a minimum amount equivalent to U.S.$500,000.

                    ------------------                                          
Multicurrency Advances shall be evidenced by a promissory note (including all
renewals, modifications, and extensions thereof, the "Multicurrency Note"), made
by Borrower to the order of Lender.  The Multicurrency Note shall be unsecured,
and shall be in substantially the same form as Exhibit B attached.

          (a)       Interest. Each Multicurrency Advance shall bear interest
                    --------
     from the date of advance until the end of its Applicable Interest Period at
     the Multicurrency Rate determined by Lender. All interest accrued on each
     such Multicurrency Advance shall be due and payable in full on the last day
     of the Applicable Interest Period applicable to such Multicurrency Advance.

          (b)       Principal. Borrower shall repay in full the outstanding
                    ---------
     principal balance of each Multicurrency Advance, in the currency advanced,
     on the last day of its Applicable Interest Period. Such repayment may be
     effected either (a) by making payment to Lender in immediately available
     funds in the same manner as provided in Section 2.8, or (b) by obtaining a
     Multicurrency Advance, pursuant to the procedures of Section 3.1, in the
     same currency and at least the same amount as the maturing Multicurrency
     Advance (but in any case not to exceed the Available Amounts), with
     instructions to Lender to apply the proceeds of such new Multicurrency
     Advance to the maturing Multicurrency Advance before disbursing the balance
     (if any) to Borrower. Lender shall have no liability for, nor bear any of
     the risk of, intra-day fluctuations in foreign exchange rates.
     Multicurrency Advances may not be prepaid prior to the end of their
     respective Applicable Interest Periods.

     Section 4.1    Issuance. Upon Borrower's execution of Lender's standard
                    --------
form Application and Agreement for Standby Credit ("L/C Agreement"), Lender
shall issue for Borrower's account a standby letter of credit ("Letter of
Credit") in an amount not to exceed $40,000,000, with an expiration date (or a
right to terminate under an evergreen expiration clause) no later than December
31, 1998, to an entity providing a supersedeas bond on Borrower's behalf to stay
the SRI Judgment (as defined in Section 8.9 of the Agreement). If there is a
draw under the Letter of Credit, Borrower shall on demand immediately reimburse
Lender for the amount of the draw, together with interest on the amount drawn,
from the date drawn, until paid, at the default rate of interest set forth in
Section 2.5(a) of the Agreement. Lender shall in addition have all rights
provided in the L/C Agreement. Any default in the L/C Agreement shall be an
Event of Default under the Agreement.

     Section 4.2    Fees.  Borrower shall pay to Lender quarterly in advance a
                    ----                                                      
commitment fee determined according to the following formula, on the date of
issuance of the Letter of Credit, and on the same day of every third month
thereafter until the Letter of Credit is no longer outstanding:  0.25% per annum
of the face amount of the Letter of Credit.  Borrower shall additionally, on
demand, pay transaction fees according to Lender's then-outstanding standard fee
schedule on all drafts, transfers, extensions, and other transactions with
regard to the Letter of Credit, and reimburse Lender for all out-of-pocket
costs, legal fees, and expenses.

     Section 4.3    Yield Indemnity.  If any law or regulation imposes or
                    ---------------

of credit issued by Lender or subjects Lender to any tax, charge, fee,
deduction, or withholding of any kind in regard to the Letter of Credit,
Borrower shall promptly on demand indemnify Lender for any such increased costs,
taxes, or charges.

     Section 4.4    Collateral.  All of Borrower's obligations under the L/C
                    ----------                                              
Agreement (the "L/C Obligations") shall be secured by:  Marketable Securities
having an Aggregate Collateral Value equal to the face amount of the Letter of
Credit.  Borrower hereby grants to Lender a security interest in investments
held in the Collateral Account.  Upon an Event of Default, Lender may instruct
the Custodian to liquidate investments and disburse to Lender all amounts
necessary for the payment in full of the L/C Obligations.  If at any time Lender
shall determine that the Aggregate Collateral Value of the Marketable Securities
in the Collateral Account is less than the amount required under this Section,
Borrower (or Guarantor if necessary) 

                                      12

shall, within three Business Days of demand by Lender, deliver for deposit to
the Collateral Account additional Marketable Securities so that the total in the
Collateral Account shall again equal the Aggregate Collateral Value.

                                   ARTICLE 6
                        REPRESENTATIONS AND WARRANTIES
                        ------------------------------

     The Borrower and Guarantor, jointly and severally, represents and warrant
to the Lender as follows:

     Section 6.1  Corporate Existence and Power.  Guarantor, Borrower, and
                  -----------------------------                           
Borrower's Subsidiaries are each a corporation duly incorporated, validly
existing and in good standing under the laws of its respective jurisdiction of
incorporation.  The Guarantor, Borrower, and Borrower's Subsidiaries are each
duly qualified to do business in each other jurisdiction where the nature of
their respective activities or the ownership of their respective properties
requires such qualification.  The Borrower and Guarantor each has full corporate
power, authority and legal right to carry on its business as presently
conducted, to own and operate its properties and assets, and to execute, deliver
and perform the Loan Documents to which it is a party.

     Section 6.2  Corporate Authorization.  The execution, delivery and
                  -----------------------                              
performance by the Borrower of this Agreement, the Multicurrency Note and the
Revolving Note, and any borrowing hereunder or thereunder, and the execution,
delivery and performance by Guarantor of this Agreement have been duly
authorized by all necessary corporate action of the Borrower or the Guarantor,
as the case may be, do not require any shareholder approval or the approval or
consent of any trustee or the holders of any Indebtedness of the Borrower or
Guarantor, except such as have been obtained (certified copies thereof having
been delivered to the Lender), do not contravene any law, regulation, rule or
order binding on the Borrower or Guarantor or the Articles of Incorporation or
Bylaws of the Borrower or Guarantor and do not contravene the provisions of or
constitute a default under any indenture, mortgage, contract or other agreement
or instrument to which the Borrower or Guarantor is a party or by which the
Borrower or Guarantor or any of their properties may be bound or affected.

     Section 6.3  Government Approvals, Etc.  No Government Approval or filing
                  --------------------------                                  
or registration with any Governmental Authority is required for the making and
performance by the Borrower or Guarantor of the Loan Documents to which it is a
party or in connection with any of the transactions contemplated hereby or
thereby, except such as have been heretofore obtained and are in full force and
effect (certified copies thereof having been delivered to the Lender).

     Section 6.4  Binding Obligations, Etc.  This Agreement, the Multicurrency
                  ------------------------                                    
Note and the Revolving Note have been duly executed and delivered by the
Borrower and constitute the legal, valid and binding obligation of the Borrower
enforceable against the Borrower in accordance with their respective terms.
This Agreement has been duly executed and delivered by the Guarantor and
constitutes the legal, valid and binding obligation of Guarantor enforceable
against it in accordance with its terms.

     Section 6.5  Litigation.  Except for the SRI judgement defined in Section
                  ----------                                                  
8.9, there are no actions, proceedings, investigations, or claims against or
affecting the Guarantor, Borrower or any of Borrower's Subsidiaries now pending
before any court, arbitrator or Governmental Authority (nor to the knowledge of
Borrower or Guarantor has any thereof been threatened, nor to the knowledge of
Borrower or Guarantor does any basis exist therefor) which if determined
adversely to the Guarantor, Borrower, or any of the Borrower's Subsidiaries
would be likely to have a material adverse effect on the consolidated financial
condition of the Guarantor or the Borrower or on the ability of the Borrower or
Guarantor to perform its obligations under the Loan Documents.

     Section 6.6  Financial Condition.  The consolidated balance sheet of the
                  -------------------                                        
Guarantor (which includes Borrower and Borrower's Subsidiaries) as of December
31, 1996, and the related consolidated statements of income, cash flows, and
shareholders' equity for the Fiscal Year then ended and the 

                                      14
<PAGE>
 
consolidated balance sheet of the Guarantor (which includes Borrower and
Borrower's Subsidiaries) as of March 28, 1997, and the related consolidated
statements of income and cash flows for the quarter then ended copies of which
have been furnished to Lender, fairly present the consolidated financial
condition of the Guarantor, Borrower, and Borrower's Subsidiaries as at such
dates and the results of consolidated operations of the Guarantor, Borrower, and
Borrower's Subsidiaries for the periods then ended, all in accordance with
generally accepted accounting principles consistently applied. The Guarantor,
Borrower and the Borrower's Subsidiaries did not have on such dates any material
contingent liabilities for Taxes, unusual forward or long-term commitments or
unrealized or anticipated losses from any unfavorable commitments, except as
referred to or reflected or provided for in that balance sheet and in the notes
to those financial statements. Since March 28, 1997, there have been no material
changes to the operations, business or financial condition of Guarantor,
Borrower and the Borrower's Subsidiaries that would be sufficient to impair the
Borrower's ability to repay any outstanding or requested Loans or Multicurrency
Advances or that have resulted in, or are forecast by Borrower or Guarantor to
result in, a Default or Event of Default.

     Section 6.7  Title and Liens.  The Guarantor, Borrower, and Borrower's
                  ---------------                                          
Subsidiaries have good and marketable title to each of the properties and assets
reflected in the balance sheet referred to in Section 6.6 (except such as have
been since sold or otherwise disposed of in the ordinary course of business or
in compliance with the terms of Section 8.6 hereof).  No assets or revenues of
the Guarantor, the Borrower, or Borrower's Subsidiaries are subject to any
material Lien except as required or permitted by this Agreement or disclosed in
the balance sheets referred to in Section 6.6 or otherwise disclosed to the
Lender in writing prior to the date of this Agreement.  All properties of the
Guarantor, Borrower, and Borrower's Subsidiaries and their respective use
thereof comply in all material respects with all applicable material zoning and
use restrictions and with applicable material laws and regulations relating to
the environment.

     Section 6.8  Taxes.  As of the date of this Agreement, the Guarantor,
                  -----                                                   
Borrower and Borrower's Subsidiaries have filed all material tax returns and
reports required of them, have paid all material Taxes which are due and
payable, and have provided adequate reserves for payment of any Tax whose
payment is being contested.  The charges, accruals and reserves on the books of
the Guarantor, Borrower, and Borrower's Subsidiaries in respect of Taxes for all
fiscal periods to date of this Agreement are accurate to the best of their
knowledge.  There are no questions or disputes between the Guarantor, Borrower,
or any Subsidiaries of Borrower and any Governmental Authority with respect to
any material Taxes except as disclosed in the balance sheets referred to in
Section 6.6 or otherwise disclosed to the Lender in writing prior to the date of
this Agreement and except disputes which if resolved adversely to the positions
being asserted by the Guarantor, Borrower, or any Subsidiary of Borrower would
not result in a material adverse change in the consolidated financial condition
of the Guarantor, Borrower, and Borrower's Subsidiaries.

     Section 6.9  Laws, Orders; Other.  Except as described in the financial
                  -------------------                                       
statements delivered to Lender pursuant to Section 6.6 neither the Guarantor nor
Borrower, is in violation of or subject to any contingent liability on account
of any material laws, statutes, rules, regulations and orders of any
Governmental Authority.  Neither the Guarantor nor Borrower is in material
breach of or default under any agreement to which it is a party or which is
binding on it or any of its assets.

     Section 6.10  Federal Reserve Regulations.  Neither the Borrower nor the
                   ---------------------------                               
Guarantor is engaged principally or as one of its important activities in the
business of extending credit for the purpose of purchasing or carrying any
margin stock (within the meaning of Federal Reserve Regulation U), and no part
of the proceeds of any Loan or Multicurrency Advance will be used to purchase or
carry any such margin stock or to extend credit to others for the purpose of
purchasing or carrying any such margin stock or for any other purpose that
violates the applicable provisions of any Federal Reserve Regulation.  The
Borrower will furnish to the Lender on request a statement conforming with the
requirements of Regulation U.

                    ----- 

          (a)       The present value of all benefits vested under all Pension
     Plans did not, as of the most recent valuation date of such Pension Plans,
     exceed the value of the assets of the Pension Plans allocable to such
     vested benefits by an amount which would represent a potential material
     liability of the Guarantor and the Borrower, taken as a whole, or affect
     materially the ability of the Borrower and Guarantor to perform this
     Agreement.

          (b)       Except as disclosed to the Lender in writing prior to the
     date hereof, no Plan or trust created thereunder, or any trustee or
     administrator thereof, has engaged in a "prohibited transaction" (as such
     term is defined in Section 406 or Section 2003(a) of ERISA) which could
     subject such Plan or any other Plan, any trust created thereunder, or any
     trustee or administrator thereof, or any party dealing with any Plan or any
     such trust to the tax or penalty on prohibited transactions imposed by
     Section 502 or Section 2003(a) of ERISA.

          (c)       No Pension Plan or trust has been terminated, except in
     accordance with the Code, ERISA, and the regulations of the Internal
     Revenue Service and the PBGC as applicable to solvent plans in which
     benefits of participants are fully protected. No "reportable event" as
     defined in Section 4043 of ERISA has occurred for which notice has not been
     waived or for which alternative notice procedures are permitted.

          (d)       No Pension Plan or trust created thereunder has incurred any
     "accumulated funding deficiency" (as such term is defined in Section 302 of
     ERISA) whether or not waived, since the effective date of ERISA.

          (e)       The required allocations and contributions to Pension Plans
     will not violate Section 415 of the Code.

     Section 6.12   Subsidiaries.  Schedule 2 to this Agreement sets forth as of
                    ------------                                                
the date of this Agreement a list of Guarantor's and Borrower's Subsidiaries.
Except as noted otherwise, all subsidiaries are wholly owned by Guarantor,
Borrower or Subsidiaries of Borrower.

     Section 6.13   Patents, Licenses, Franchises.  To the best of their
                    -----------------------------                       
knowledge, the Guarantor, Borrower, and each of Borrower's Subsidiaries owns or
possesses all the patents, trademarks, service marks, trade names, copyrights,
licenses, franchises, permits and rights with respect to the foregoing necessary
to own and operate its properties and to carry on its business as presently
conducted and presently planned to be conducted without material conflict with
the valid rights of others except as previously disclosed in writing to the
Lender prior to the date hereof.

     Section 6.14   Investment Company; Public Utility Holding Company.  Neither
                    --------------------------------------------------          
the Borrower nor the Guarantor is (a) an "investment company" or a company
"controlled" by an investment company within the meaning of the Investment
Company Act of 1940, as amended; or (b) a "holding company" or a "subsidiary
company" of a "holding company" or an "affiliate" of either a "holding company"
or a "subsidiary company" within the meaning of the Public Utility Holding
Company Act of 1935, as amended.

effect their corporate existence and shall comply with all laws applicable to

     Section 7.6  Maintenance of Property.  The Borrower and Guarantor shall,

Guarantor's knowledge, threatens to result in a strike which would significantly
affect the consolidated financial condition of Guarantor or Borrower; (c) if

to give notice to the PBGC of any "reportable event" (as defined in subsections
(b)(1), (2), (5) or (6) of Section 4043 of ERISA) with respect to any Plan (or

                                   RECITALS:
                                        
  A.  Seafirst made a loan to Borrower in the original principal amount of
$11,500,000 (the "LOAN") evidenced by a Promissory Note dated December 28, 1994,
made by Borrower, payable to Seafirst or order (the "NOTE").  The Loan is
secured by a Deed of Trust, Security Agreement and Fixture Filing with
Assignment of Leases and Rents dated December 28, 1994 (the "DEED OF TRUST"),
made by Borrower as Grantor, for the benefit of Seafirst, which constitutes a
first lien encumbrance on the real property described on Schedule A attached to
                                                         ----------            
this Agreement, and the collateral described in the Deed of Trust or in any
uniform commercial code financing statement filed with respect thereto
(collectively the "PROPERTY").  The Deed of Trust is recorded in the real
property records of Snohomish County, Washington under Recording No. 9412290067.
The Note, the Deed of Trust and all other documents evidencing and securing the
Loan are collectively referred to in this Agreement as the "LOAN DOCUMENTS".  In
addition to the Loan Documents, Borrower executed and delivered to Seafirst in
connection with the Loan, a Certificate and Indemnity Agreement Regarding
Building Laws and Hazardous Substances, dated as of December 28, 1994 (the
"CERTIFICATE AND INDEMNITY").

  B.  Guarantor guaranteed the payment and performance of Borrower's obligations
under the Loan Documents and the Certificate and Indemnity pursuant to a
separate Guaranty of Payment and Performance dated December 28, 1994 (the
"GUARANTY").

  C.  Lender is the present holder of the Note and of all of the rights and
interests of Seafirst under the Loan Documents, the Certificate and Indemnity
and the Guaranty.  Borrower and Lender have agreed to make certain modifications
to the Loan Documents, and Lender has agreed to make an additional loan to
Borrower which will be secured by the Deed of Trust and guaranteed by Guarantor.

                                  AGREEMENT:

     In consideration of the mutual covenants contained in this Agreement,
Borrower, Lender and Guarantor agree as follows:

  1.  Modification to Loan Documents.
      ------------------------------ 

      (a) Note.  From and after the effective date of this Agreement, the Note
          ----       
 is amended as follows:

          (i)  The Variable Rate applicable to the Note will be adjusted to an
interest equal to the "LIBOR Index" (as defined in the Note) as of the effective
date of this 

                                      -2-
 
<PAGE>
 
Agreement, plus nine-tenths of one percentage point (.90%) per annum. Monthly
principal and interest payments at such Variable Rate will commence on July 20,
1998, and the next Interest Change Date for purposes of the Note will be
December 20, 1998.

          (ii)  Subparagraph 2(a)(ii) is amended to read as follows:

     Before each Interest Change Date, if applicable, the Holder will calculate
     the new Variable Rate which shall be equal to the Current Index, plus nine-
     tenths of one percentage point (.90%) per annum.  This new interest rate
     will be the new Variable Rate until the next Interest Change Date.

          (iii) The first sentence of subparagraph 2(b)(i) is amended to read as
follows:

     If Maker elects to have a Fixed Rate apply to this Note, interest shall
     accrue on the principal balance of this Note at a per annum rate equal to
     Lender's reserve adjusted "FIXED RATE INDEX" as quoted by Lender on the
     date the interest rate is fixed, for a period equivalent to the applicable
     Fixed Rate Period, plus nine-tenths of one percentage point (.90%) per
     annum.
 
          (iv) Paragraph 3 is amended to provide that the required monthly
payments of principal and interest shall be due on the twentieth (20th) day of
each month during the term of the Note.

          (v) Paragraph 16 is amended to read as follows:

          16.  CROSS DEFAULT.  Maker, as borrower, Lender, as lender, and ATL

     Agreement and Guaranty dated July 1, 1997, as amended from time to time
     (the "LOAN AGREEMENT"). In addition, Lender is the current holder of a
     Promissory Note dated June 3, 1998, in the original principal amount of
     $17,000,000, also secured by the Deed of Trust, made by Maker and payable
     to the order of Lender (the "ADDITIONAL NOTE "). Maker agrees if Maker or
     ATL Ultrasound Inc. defaults under the Loan Agreement, or if Maker defaults
     under the Additional Note, and in either case the default is not cured
     prior to the expiration of the applicable cure period, if any, such default
     will constitute a default under this Note and the other Loan Documents and
     no additional notice of default shall be required under Paragraph 6 of this
     Note.

          (b) Deed of Trust.  Paragraph 5(a) of Article I of the Deed of Trust
              -------------       
is hereby amended as follows:

                      GUARANTY OF PAYMENT AND PERFORMANCE


  This Guaranty is made as of June 16th, 1998 by ATL ULTRASOUND, INC., a
Washington corporation, formerly known as ADVANCED TECHNOLOGY LABORATORIES,
INC., a Delaware corporation ("GUARANTOR"), to BANK OF AMERICA NATIONAL TRUST
AND SAVINGS ASSOCIATION, doing business as SEAFIRST BANK, and its successors,
participants and assigns ("LENDER").

                                 RECITALS:

  A.  Pursuant to a Promissory Note of even date executed by Borrower to the
order of Lender, Lender has agreed to make a loan (the "LOAN") to ADVANCED
TECHNOLOGY LABORATORIES, INC., a Washington corporation ("BORROWER"), in the
amount of Seventeen Million Dollars ($17,000,000).  The Loan is secured by a
Deed of Trust, Security Agreement and Fixture Filing with Assignment of Leases
and Rents dated December 28, 1994, made by Borrower as Grantor, recorded in the
real property records of Snohomish County, Washington under Recording No.
9412790067, as amended by a Loan Modification Agreement of even date among
Lender, Borrower and Guarantor.  In addition to the foregoing documents,
Borrower has executed and delivered to Lender in connection with the Loan
certain other documents, all of which are collectively referred to in this
Guaranty as the "LOAN DOCUMENTS"; except the term Loan Documents does not
include that certain Certificate and Indemnity Agreement Regarding Hazardous
Substances and Building Laws dated December 28, 1994 made by Borrower for the
benefit of Lender (the "CERTIFICATE AND INDEMNITY AGREEMENT").

  B.  Guarantor has agreed to unconditionally guarantee the full and punctual
payment and performance of the "GUARANTEED OBLIGATIONS" (defined below).  As
used in this Guaranty, the term "GUARANTEED OBLIGATIONS" means all debts,
duties, undertakings, obligations, covenants and conditions to be paid or
performed by Borrower in connection with the Loan, including without limitation
all of Borrower's obligations under the Loan Documents, the Certificate and
Indemnity Agreement, and under each and every existing or future "swap"
transaction (i.e., any transactions governed by an ISDA master agreement)
between Lender and Borrower (or any other obligor of the Loan), in which this
Guaranty is expressly referred to as a credit support document, and any and all
extensions, renewals or modifications thereof, including the obligations to pay
as and when due principal, interest, attorneys' fees and all other debts of
Borrower arising under and by reason of the Loan Documents and the Certificate
and Indemnity Agreement.

                                 AGREEMENT:

  For good and valuable consideration, the receipt and sufficiency of which are
acknowledged, Guarantor agrees as follows:

                                      -1-
<PAGE>
 
  1.  Guarantee.  Guarantor unconditionally guarantees to and for the benefit of
      ---------                                                                 
Lender the full, prompt and complete payment and performance by Borrower of the
Guaranteed Obligations.  If any of Borrower's obligations, covenants, and
agreements under the Loan Documents or under the Certificate and Indemnity
Agreement are not paid or performed as and when such payment or performance is
due or required, on demand from Lender, Guarantor will pay or perform the same.

  2.  Independent Obligation.  This Guaranty is an independent obligation of
      ----------------------                                                
Guarantor, separate and distinct from the Guaranteed Obligations.  A separate
action may be brought or prosecuted against Guarantor, whether or not any such
action is brought or prosecuted against Borrower or whether Borrower is joined
in any such action or actions.  This Guaranty is an absolute guarantee of
payment and performance, and not a guarantee of collection.  The obligations of
Guarantor under this Guaranty are direct and primary, regardless of the validity
or enforceability of the Loan Documents or the Certificate and Indemnity
Agreement or any renewal, extension or modification thereof.  Guarantor shall
continue to be liable under this Guaranty even if all or part of the Guaranteed
Obligations become uncollectible by operation of law or otherwise.

  3.  Waivers.  Guarantor waives (a) notice of Lender's acceptance of this
      -------                                                             
Guaranty; (b) notice of any advances made by Lender pursuant to the Loan
Documents or the Certificate and Indemnity Agreement, or pursuant to any
extension, renewal or modification thereof; (c) any defense arising from or out
of the exercise by Lender of any right or remedy it may have with respect to the
Guaranteed Obligations; (d) grace, demand, presentment, notice of dishonor and
protest with respect to the Guaranteed Obligations; (e) any defense based upon
any change in the name, location, composition or structure of Borrower, or any
change in the type of business conducted by Borrower, or any other change in the
financial condition, identity or legal status of Borrower; (f) the benefit of
suretyship defenses generally; and (g) any defense based upon any failure by
Lender to obtain a similar guaranty from any other person or entity, or file a
creditor's claim in the estate of any person or entity, including Borrower,
whether in administration, bankruptcy or any other proceeding.

  4.  Rights of Lender.  Lender shall not be bound to exhaust its recourse or
      ----------------                                                       
take any action against Borrower or against any other person or entity, or
proceed against any collateral or against any particular collateral, but Lender
may make such demands and take such actions as it deems advisable, and Lender,
without affecting the liability of any Guarantor under this Guaranty, may with
or without notice or consideration (i) release any other person or entity liable
for the Guaranteed Obligations; (ii) extend the maturity, modify the terms,
grant any indulgence or forbearance or postpone the time of payment of the
Guaranteed Obligations or otherwise amend or modify the terms of any agreement
or instrument giving rise to all or any of the Guaranteed Obligations; and (iii)
release all or any part of the existing or any future security for the
Guaranteed Obligations.  All rights and remedies of Lender under this Guaranty,
at law or in equity are separate and cumulative and may be pursued separately,
successively, or concurrently, or not pursued, 

                                      -2-
<PAGE>
 
without affecting or limiting any other right or remedy of Lender and without
affecting or impairing the liability of Guarantor under this Guaranty.

  5.  Waiver of Subrogation and Reimbursement Rights.  To the fullest extent
      ----------------------------------------------                        
permitted by applicable law, Guarantor releases and waives any claim, right or
remedy which Guarantor may have against Borrower arising from this Guaranty
and/or from the performance by Guarantor of his, her or its obligations under
this Guaranty, including any claim, remedy or right of subrogation,
reimbursement, exoneration, contribution, indemnification or participation in
any claim, right or remedy of Lender against Borrower, or any security which
Lender now has or hereafter acquires, whether such claim, right or remedy arises
under contract, by statute, under common law or otherwise.

  6.  Subordination of Debt.  Any present or future indebtedness of Borrower to
      ---------------------                                                    
Guarantor is hereby subordinated to the Guaranteed Obligations.  Any payment of
such indebtedness of Borrower to Guarantor shall be collected, enforced and
received by Guarantor in trust for the benefit of Lender and promptly paid over
to Lender on account of the Guaranteed Obligations, but without reducing or
affecting in any manner the liability of such Guarantor under the other
provisions of this Guaranty.

  7.  Guaranty Survives Foreclosure.  Lender, at its option and in its sole
      -----------------------------                                        
discretion, may proceed against any collateral securing the Guaranteed
Obligations by way of either judicial or non-judicial foreclosure and the
obligations of Guarantor under this Guaranty shall survive such foreclosure.
Guarantor understands a non-judicial foreclosure of any deed of trust securing
the Guaranteed Obligations could impair or eliminate any subrogation or
reimbursement rights Guarantor may have against Borrower; nevertheless Guarantor
hereby waives and relinquishes any defense based upon the loss of any such
reimbursement or subrogation rights and any other defense which may arise out of
RCW 61.24, as now or hereafter amended or any legislation in substitution or
replacement thereof, including without limitation any defense based upon the
Washington Anti-Deficiency Statute, RCW 61.24.100, as now or hereafter amended,
and any defense that may arise out of election of remedies, or discharge or
satisfaction of the Guaranteed Obligations pursuant to RCW 61.24.100.  If any
deed of trust securing the Guaranteed Obligations is foreclosed judicially or
non-judicially before Lender proceeds against Guarantor under this Guaranty,
Guarantor's liability for the obligations secured by such deed of trust shall be
the deficiency resulting from the judicial or non-judicial sale; i.e., the
difference between the amount of the obligations secured by the deed of trust on
the day of the foreclosure sale (including without limitation principal, accrued
interest, attorneys' fees, late charges and costs of foreclosure) and the amount
of the successful bid at the foreclosure sale.  Guarantor further waives the
right to object to the amount which may be bid by Lender at any foreclosure
sale.

  8.  Application of Payments.  Lender may apply any payments received by it
      -----------------------                                               
from any source against any portion of the Guaranteed Obligations in such order
and priority as Lender may deem appropriate.

  9.  Continuing Guaranty.  This Guaranty covers any and all of the Guaranteed
      -------------------                                                     
Obligations, whether presently outstanding or arising subsequent to the date of
this Guaranty.  This Guaranty shall continue until each and every Guaranteed
Obligation is paid and performed in full.  If at any time payment or performance
of all or any part of the Guaranteed Obligations is rescinded or must otherwise
be restored or returned by Lender as a result of the insolvency, bankruptcy or
reorganization of Borrower or otherwise, this Guaranty shall be reinstated.
Guarantor hereby assigns to Lender all rights against Borrower, related to the
Guaranteed Obligations, which Guarantor may have in any proceedings under the
United States Bankruptcy Code or in any receivership or other insolvency
proceeding.  This Guaranty is binding upon and enforceable against Guarantor and
its devisees, personal representatives, successors and assigns. This Guaranty is
intended for and shall be binding upon and inure to the benefit of Lender and
each and every person or entity who, by assignment, endorsement, participation
agreement or otherwise, succeeds to all or any part of Lender's rights under the
Guaranteed Obligations, irrespective whether such transfer is voluntary or
involuntary or occurs by operation of law.

  10.  Financial Statements.  Except as otherwise agreed in writing by Lender,
       --------------------                                                   
within ninety (90) days after the end of each of its fiscal years, Guarantor
shall provide Lender with a CPA audited financial statement showing its
financial condition as of the end of the most recent fiscal year, prepared in
accordance with generally accepted accounting principles, consistently applied.
Upon request, Guarantor will provide Lender with a copy of his, her or its
United States federal income tax return for the tax year most recently ended.

  11.  Governing Law; Jurisdiction; Venue.  This Guaranty shall be governed by
       ----------------------------------                                     
and construed in accordance with the laws of the State of Washington.  Guarantor
hereby submits irrevocably to the non-exclusive jurisdiction and venue of any
state or federal court in the State of Washington selected by Lender in any
action relating to or arising out of the enforcement or interpretation of this
Guaranty and Guarantor hereby irrevocably agrees that all claims in respect to
any such action or proceeding may be heard and determined in such Washington
State Court or such United States District Court sitting in the State of
Washington and to all the courts to which an appeal may be taken from such
courts.  Guarantor expressly waives, to the fullest extent it may effectively do
so under applicable law, any objection it may at any time have:  (a) as to venue
in such courts; (b) that any action or proceeding therein has been brought in an
inconvenient forum; (c) that any such court lacks jurisdiction over it; or (d)
as to service of process upon it in accordance with applicable law.

  12.  Costs and Expenses.  Whether or not suit is brought, Guarantor shall pay
       ------------------                                                      
on demand all costs and expenses, including reasonable attorneys' fees incurred
by or on behalf of Lender in connection with the enforcement against or
collection from Borrower of all or any of the Guaranteed Obligations, or any
security therefor, or in connection with the enforcement, interpretation or
defense of this Guaranty to the extent Lender is the prevailing party.  Without
limiting the generality of the foregoing, if Borrower or Guarantor becomes the
subject of any bankruptcy or other insolvency proceeding, Guarantor shall pay
all reasonable costs and expenses incurred by Lender in connection with such
bankruptcy or insolvency proceeding.

                                      -4-

  13.  Representations and Warranties.  Guarantor represents and warrants to
       ------------------------------                                       
Lender that it (a) is adequately informed of the financial condition of
Borrower; (b) has not relied on any financial information about Borrower
furnished by Lender; and (c) does not expect Lender to provide any such
information in the future.  Furthermore, Guarantor acknowledges Lender would not
make the Loan to Borrower without this Guaranty, and Guarantor has reviewed the
Loan Documents and the Certificate and Indemnity and is otherwise fully familiar
with the Guaranteed Obligations.

  14.  Miscellaneous.  The obligations of Guarantor under this Guaranty shall be

independent of the obligations of Borrower and any other persons or entities
guaranteeing the payment or performance of the Guaranteed Obligations.  The
obligations and liabilities of Guarantor hereunder shall not be limited in any
manner by any nonrecourse or other provisions in the Loan Documents or in the
Certificate and Indemnity Agreement which may limit the liability or obligations
of Borrower with respect to the Guaranteed Obligations.  This Guaranty may be
executed in multiple counterparts, each counterpart shall be an original, but
all counterparts together will constitute one and the same agreement.

                                                                   June 16, 1998
                                                             Seattle, Washington


  FOR VALUE RECEIVED, the undersigned ("MAKER") promise(s) to pay to the order
of BANK OF AMERICA NATIONAL TRUST AND SAVINGS ASSOCIATION, doing business as
SEAFIRST BANK ("LENDER"), at its principal office in Seattle, Washington, or at
such other place or places or to such other party as the "HOLDER" (defined
below) may from time to time designate in writing, the principal sum of
SEVENTEEN MILLION AND 00/100 DOLLARS ($17,000,000), or so much thereof as may be
advanced, in lawful money of the United States of America, together with
interest thereon, on the following agreements, terms and conditions.  The term
"HOLDER" as used in this Note means Lender or any future holder of this Note,
and its successors and assigns.

  1.  TERM.  The unpaid principal balance of this Note and all unpaid accrued
      ----                                                                   
interest thereon and other sums payable by Maker in connection with this Note
shall be due and payable in full one hundred twenty (120) months from the first
day of the first calendar month following the initial advance by the Holder
under this Note (the "MATURITY DATE").

  2.  INTEREST.  Interest shall commence to run on each advance under this Note
      --------                                                                 
from the date of the advance and will be computed on the unpaid principal
balance of this Note as it exists from time to time.  Interest shall accrue on
the principal balance of this Note either at a variable interest rate as
provided in subparagraph 2(a) below (the "VARIABLE RATE"), or at a fixed
interest rate as provided in subparagraph 2(b) below (the "FIXED RATE").  If
Maker elects a Fixed Rate pursuant to subparagraph 2(b) below for a "Fixed Rate
Period" (defined below) less then full term of this Note (or the remainder
thereof, as applicable), after the expiration of the applicable Fixed Rate
Period, interest on this Note shall be calculated at a Variable Rate unless
Maker again elects to have interest calculated at a Fixed Rate pursuant to
subparagraph 2(b) below.  The Holder still shall have no duty or obligation to
notify Maker that a Fixed Rate Period is about to expire and that the interest
rate on this Note is about to revert to the Variable Rate.  After maturity, or
after default, interest shall accrue on the unpaid principal balance of this
Note at an annual rate equal to four percentage points (4%) per annum above the
interest rate otherwise applicable to this Note.  Interest on this Note shall be
calculated using a 30-day month and a 360-day year.

      (a) Variable Rate. Unless Maker elects to have interest calculated at the
          -------------
Fixed Rate pursuant to subparagraph 2(b) below, interest shall accrue on the
principal balance of this Note at the Variable Rate. The initial Variable Rate
shall be equal to the "LIBOR INDEX" (defined below) as of the date of the
initial advance under this Note, plus nine-tenths of one percentage point (.90%)
per annum. The Variable Rate, if applicable, will change five (5) months after
the first payment date at the applicable Variable Rate, as stated in Paragraph 3
below, and every sixth (6th) month thereafter (each such date being referred to
in this Note as an "INTEREST CHANGE DATE").

                                      -1-
<PAGE>
 
             (i) LIBOR INDEX - CURRENT INDEX - Changes in the Variable Rate will
be based on changes in the 180-day LIBOR as defined below (the "LIBOR INDEX").
If the LIBOR Index is no longer available, the Holder and Maker will choose a
new index based upon comparable information. The most recently available LIBOR
Index fifteen (15) Business Days before each Interest Change Date is the
"CURRENT INDEX".

             (ii) CALCULATION OF VARIABLE RATE - Before each Interest Change
Date, if applicable, the Holder will calculate the new Variable Rate which shall
be equal to the Current Index, plus nine-tenths of one percentage point (.90%)
per annum. This new interest rate will be the new Variable Rate until the next
Interest Change Date.

             (iii) LIBOR MEANS THE LONDON INTERBANK OFFER RATE, adjusted at the
Holder's option for governmentally mandated statutory reserves, deposit
insurance, regulatory capital, taxes and assessments, if any, and is the average
of the rates of interest, on a per annum basis, at which deposits in United
States dollars having a term of 180 days are offered by major banks in
immediately available funds to prime banks in the London Interbank market at
11:00 A.M. (London time) on the date of the initial advance, or the day which is
fifteen (15) Business Days prior to the applicable Interest Change Date, as
applicable. This rate is reported on Telerate, a national and international
medium which provides interest rate quotations daily, as quoted by the British
Bankers Association as Interest Settlement Rates on page 3750 (or such other
page as may replace it). Such interest rate quotation, as provided by Telerate,
shall be deemed conclusive and final with respect to LIBOR determinations for so
long as Telerate continues to make such interest rate reports. If Telerate or
the British Bankers Association report is no longer available for 180-day
maturities, a comparable publication or report containing such information
selected by the Holder and Maker will be used. If there is no such publication
or comparable publication containing such information, the 180-day LIBOR shall
be the average rate (rounded if necessary to the nearest one-thousandth of a
percent) at which dollar deposits having a maturity of 180 days are offered by
at least two major banks in an interbank market where Eurodollars are being
traded, to prime banks in immediately available funds on the LIBOR determination
date described above or as soon thereafter as such offer quotes can be obtained.

             (iv) BUSINESS DAY means a day on which commercial banks are
generally open for business in Seattle, Washington and London, England.

             (v) THE AMOUNT OF ADJUSTMENT for reserves, deposit insurance,
regulatory capital, taxes and assessments may change on any Interest Change Date
depending on such charges being assessed against the Holder at that time,
provided that the adjustments are of general application to similar obligations
held by the Holder and not specific to this Note. Such charges may change due to
various factors, including but not limited to, changes in the requirements for
reserves and capital adequacy promulgated by the Federal Reserve System of the
United States and/or other state and federal regulatory agencies, statutory
changes affecting the Holder, and/or imposition of taxes, FDIC fees and/or
assessments. Each determination of an adjustment amount shall be made by the
Holder in its reasonable discretion and shall be conclusive and binding upon
Maker absent manifest error by the Holder. If the circumstances giving rise to
an 

                                      -2-
<PAGE>
 
adjustment pursuant to this subparagraph cease to exist, the Holder will make
an appropriate re-adjustment with respect to interest rate determinations
occurring thereafter.

      (b) Fixed Rate. Prior to the date of the initial advance by Lender under
          ----------
this Note, Maker may elect by written notice (a "FIXED RATE NOTICE") to the
Holder to have interest on the entire principal amount of this Note calculated
at a Fixed Rate for a Fixed Rate Period, the duration of which is the entire
term of this Note or a lesser period of three (3) years, five (5) years or seven
(7) years. Further, so long as Maker is not in default under the terms of this
Note or any other documents or instruments executed by Maker in connection with
the loan (the "LOAN") evidenced by this Note (collectively with this Note, the
"LOAN DOCUMENTS"), Maker, at its option, may elect by a Fixed Rate Notice to the
Holder to have interest calculated on the entire unpaid principal balance of
this Note at a Fixed Rate calculated as provided below for a Fixed Rate Period,
the duration of which is the remainder of the term of this Note or a lesser
period of three (3) years, five (5) years or seven (7) years; provided no Fixed
Rate Period may extend beyond the Maturity Date. Notwithstanding any of the
foregoing, Maker's option to fix the interest rate on this Note is subject to
the availability to the Holder of matchfunding opportunities for a time period
equivalent to the applicable Fixed Rate Period. For purposes of this Note, the
term "Fixed Rate Period" means the period of time for which a Fixed Rate applies
as specified in a Fixed Rate Notice from Maker to the Holder.

                 (i) CALCULATION OF FIXED RATE - If Maker elects to have a Fixed
Rate apply to this Note, interest shall accrue on the principal balance of this
Note at a per annum rate equal to Lender's reserve adjusted "FIXED RATE INDEX"
as quoted by Lender on the date the interest rate is fixed, for a period
equivalent to the applicable Fixed Rate Period, plus nine-tenths of one
percentage point (.90%) per annum. The Fixed Rate Index may be adjusted at the
Holder's option to reflect governmentally mandated statutory reserves, deposit
insurance, regulatory capital, taxes and assessments, if any, as set forth in
subparagraph 2(a)(v) above.

                 (ii) DATE OF CONVERSION - The interest rate applicable to this
Note will be converted to the Fixed Rate on the date the Holder receives a Fixed
Rate Notice, provided the Fixed Rate Notice is received before noon, Seattle
time, on a Business Day. If a Fixed Rate Notice is received by Holder after
noon, Seattle time, on a Business Day, the interest rate applicable to this Note
will convert to a Fixed Rate on the next Business Day. For purposes of this
subparagraph 2(b)(ii) only, the term "BUSINESS DAY" means a day on which
commercial banks are generally open for business in Seattle, Washington.

  3.  PAYMENTS.  Maker shall make monthly payments of principal and interest to
      --------                                                                 
the Holder in amounts sufficient to fully amortize the principal balance of this
Note over a twenty-five (25) year amortization period in substantially equal
monthly payments, based on the interest rate applicable to this Note, calculated
as provided below.  Such monthly payments of principal and interest shall be due
on the twentieth (20th) day of each calendar month during the term of this Note,
commencing on the twentieth (20th) day of the first calendar month following the
month in which the Holder initially disburses funds under this Note, or if the
interest rate reverts to a Variable Rate after the expiration of a Fixed Rate
Period, on the twentieth (20th) day of the first calendar month following the
month in which the Fixed Rate Period expires.  On the Maturity Date, the unpaid

                                      -3-
<PAGE>
 
principal balance of this Note, all unpaid accrued interest and all other sums
then due and owing pursuant to this Note or any other Loan Documents shall be
due and payable in full.  Each payment shall be applied first, at Holder's
option, to any unpaid late charges or other sums payable by Maker under this
Note or any other Loan Document, then to interest to the due date of the
payment, and then to the principal balance of this Note.  At the option of the
Holder, all payments under this Note, including payments at maturity, shall be
made in same day funds.  The monthly payments required on this Note shall be
calculated as follows:

      (a)    Variable Rate Payments. If interest is accruing on this Note at a
             ----------------------
Variable Rate, the amount of the monthly payments shall be sufficient to fully
amortize the principal balance of this Note at the applicable Variable Rate, in
substantially equal monthly payments over the amortization period specified
above, or the balance thereof as applicable. AT OR PROMPTLY AFTER THE CLOSING OF
THE LOAN (OR AFTER THE EXPIRATION OF A FIXED RATE PERIOD, AS APPLICABLE), THE
HOLDER WILL PROVIDE MAKER WITH A CLOSING STATEMENT (OR OTHER WRITTEN NOTICE)
WHICH WILL CONFIRM THE VARIABLE RATE AND THE AMOUNT OF THE PRINCIPAL AND
INTEREST PAYMENTS DUE UNDER THIS NOTE. The monthly payment will change after
each Interest Change Date to an amount sufficient to repay the then unpaid
principal balance of this Note in full at the then current interest rate, in
substantially equal monthly payments over the balance of the amortization period
specified above. Until the payment is again changed, Maker shall pay the new
monthly payment each month beginning on the twentieth (20th) day of the first
calendar month after the applicable Interest Change Date. The Holder will mail
or deliver to Maker a notice of any changes in the Variable Rate applicable to
this Note, and any resulting changes in the monthly payments required under this
Note, prior to the date the first payment is due after the applicable Interest
Change Date.

      (b) Fixed Rate Payments. If interest is accruing on this Note at a Fixed
          -------------------
Rate, the amount of the monthly payments shall be in an amount sufficient to
fully amortize the principal balance of this Note at the applicable Fixed Rate,
in substantially equal monthly payments over the amortization period specified
above, or the remainder thereof, as applicable. THE APPLICABLE FIXED RATE AND
THE AMOUNT OF THE MONTHLY PRINCIPAL AND INTEREST PAYMENTS DUE UNDER THIS NOTE
SHALL BE CONFIRMED IN WRITING BY THE HOLDER (EITHER PURSUANT TO A CLOSING
STATEMENT OR OTHER WRITTEN NOTICE) AFTER THE RATE IS FIXED AND BEFORE THE DATE
THE FIRST PAYMENT AT THE FIXED RATE IS DUE.

  4.  LATE CHARGES; RETURNED ITEM FEE.  If any payment due hereunder is not
      -------------------------------                                      
received by the Holder within fifteen (15) days following the due date, at the
option of the Holder without waiving such default or any of its remedies, a late
charge shall be added to the delinquent payment in the amount of four percent
(4%) of the full payment not timely paid.  Any such late charge shall be due and
payable on demand, and the Holder, at its option, may (a) refuse any late
payment or any subsequent payment unless accompanied by the applicable late
charge, (b) add the late charge to the principal balance of this Note, (c) pay
any late charge with advances of the undisbursed proceeds of the Loan, if any,
or (d) treat the failure to pay the late charge as demanded as a default under
this Note.  If a late charge is added to the principal balance of this Note, it
shall bear interest at the same rate as the principal balance of this Note.  Any
payment to Holder by check, draft or other item shall be received by Holder
subject to collection and will constitute payment when collected not when
received.  For each "nsf" or returned check, draft or other item, 

                                      -4-

in addition to any applicable late charge, Maker shall pay to the Holder on
demand a returned item fee in accordance with the Holder's schedule of such fees
then in effect.

  5.  PREPAYMENT.  So long as interest is calculated on this Note at a Variable
      ----------                                                               
Rate, this Note may be prepaid in whole or in part at any time without the
payment of a prepayment fee.  During any period when a Fixed Rate is applicable
to this Note, this Note may be prepaid only as set forth in Exhibit A attached.
                                                            ---------           
Partial prepayments, if permitted, shall not postpone nor reduce the amount of
the monthly payments required under this Note, provided the amount of the
required monthly payments will be recalculated at the end of the applicable
LIBOR period or Fixed Rate Period to reflect the reduction in the principal
balance of this Note.

  6.  DEFAULT.  After a default under any of the Loan Documents, or if Maker
      -------                                                               
fails to make any payment under this Note when due, the then Holder, at its
option, without notice to Maker (except as provided below), may declare the
entire principal balance of this Note and all unpaid accrued interest thereon
and other charges payable by Maker pursuant to this Note or any other Loan
Document, immediately due and payable in full, and the Holder may exercise any
and all other rights or remedies available to it under any Loan Document, at law
or in equity.  Any additional interest due because of a default shall accrue
from the date of default and shall be paid as a condition to the curing of the
default.  Notwithstanding the foregoing, the Holder will not accelerate the
Maturity Date (a) because of a monetary default by Maker under this Note or any
other Loan Document unless the default is not cured within ten (10) days
following the date on which the Holder mails or delivers written notice of the
default to Maker, or (b) because of a nonmonetary default by Maker under this
Note or any other Loan Document unless the default is not cured within thirty
(30) days following the date on which the Holder mails or delivers written
notice of the default to Maker.  For purposes of this Note, the term "MONETARY
DEFAULT" means a failure by Maker to make any payment required pursuant to this
Note or any other Loan Document, and the term "NONMONETARY DEFAULT" shall mean a
failure by Maker to perform any obligation contained in this Note or any other
Loan Document, other than the obligation to make the payments provided for in
this Note or any other Loan Document.  If the nonmonetary default is capable of
being cured and cannot reasonably be made within the thirty (30) day cure
period, the cure period shall be extended up to ninety (90) days so long as
Maker has commenced action to cure within the thirty (30) day cure period, and
in the Holder's reasonable opinion, Maker is proceeding to cure the default with
due diligence.  None of the foregoing shall be construed to obligate the Holder
to forbear in any other manner from exercising its remedies and the Holder may
pursue any other rights or remedies which the Holder may have because of the
default.

  7.  CUMULATIVE REMEDIES.  The rights and remedies of any Holder under this
      -------------------                                                   
Note or any other Loan Document, or at law or in equity, shall be cumulative and
concurrent, may be pursued singly, successively or together against Maker, any
guarantor of this Note, or any security for this Note.  A failure by any Holder
to exercise its option to accelerate this Note upon the occurrence of a default
or to exercise any other rights to which it may be entitled shall not constitute
a waiver of the right to exercise such option or any such rights in the event of
any subsequent default, whether of the same or a different nature.

  8.  WAIVERS.  Maker and all endorsers, guarantors and all other persons or
      -------                                                               
entities who may become liable for all or any part of the obligations evidenced
by this Note, jointly and severally: waive diligence, presentment, protest and
demand, and also notice of protest, demand, non-payment, dishonor or maturity
and also recourse to suretyship defenses generally; and consent to any and all
renewals, extensions and modifications of the terms of this Note or any other
Loan Document, including the time for payment, and agree any such renewal,
extension or modification or the release or substitution of any security for the
indebtedness evidenced by this Note or any other indulgences, shall not affect
the liability of said parties for the indebtedness evidenced by this Note.  Any
such renewals, extensions, modifications, releases or indulgences may be made
without notice to such parties.

  9.  COSTS AND EXPENSES.  Whether or not suit is brought Maker shall pay on
      ------------------                                                    
demand all costs and expenses, including reasonable attorneys' fees and costs
incurred by or on behalf of the Holder in connection with this Note, including
without limitation costs incurred in the collection of this Note, in protecting
the security for this Note or in foreclosing or enforcing this Note or any other
Loan Document, or resulting from the Holder being made a party to any litigation
because of the existence of this Note or any other Loan Document to the extent
the Holder is the prevailing party.  Without limiting the generality of the
foregoing, if Maker becomes the subject of any bankruptcy or insolvency
proceeding, Maker shall pay all reasonable fees and expenses incurred by the
Holder in connection with such bankruptcy or insolvency proceeding.

  10.  MAXIMUM INTEREST.  Maker represents and warrants the proceeds of this
       ----------------                                                     
Note shall be used solely for commercial, investment and business purposes, and
not for personal, family or household purposes.  Notwithstanding any other
provision of this Note or any other Loan Document, interest, loan fees and
charges payable by reason of the indebtedness evidenced by this Note shall not
exceed the maximum, if any, permitted by applicable law.  If by virtue of
applicable law, sums in excess of such maximum would otherwise be payable, then
such excess sums shall be construed as having been immediately applied by the
Holder to the principal balance of this Note when received.  If at the time any
such sum is received by the Holder, the principal balance of this Note has been
paid in full, such sums shall be promptly refunded by the Holder to Maker, less
any sums due to the Holder.

  11.  SECURITY.  This Note is secured by a Deed of Trust, Security Agreement
       --------                                                              
and Fixture Filing with Assignment of Leases and Rents  (the "DEED OF TRUST")
made by Borrower, dated December 28, 1994, recorded in the real property records
of Snohomish County, Washington under recording no. 9412290067, as amended by a
Loan Modification Agreement of even date among Maker, Lender and ATL Ultrasound,
Inc. ("ATL").  The Deed of Trust encumbers certain real property of Maker
located in Snohomish County, Washington (the "PROPERTY").  Unless otherwise
specified in this Note, all notices given pursuant to this Note must be in
writing and will be effectively given if given in accordance with the terms of
the Deed of Trust.

  12.  GENERAL.  This Note shall be binding upon Maker and Maker's successors
       -------                                                               
and assigns.  If Maker consists of more than one person or entity, all of such
persons and entities shall be jointly and severally liable for Maker's
obligations under this Note.  This Note is governed by and shall be construed in
accordance with the laws of the State of Washington.  Each person or 

                                      -6-
<PAGE>
 
entity executing this Note consents to the non-exclusive personal jurisdiction
and venue of the courts of the State of Washington and the United States federal
courts located therein, in any action relating to or arising out of the
enforcement or interpretation of this Note or any other Loan Document. Each such
person or entity further agrees not to assert in any such action that the
proceeding has been brought in an inconvenient forum.

  13.  ARBITRATION.  Any dispute relating to this Note or the Loan (whether in
       -----------                                                            
contract or tort) shall be settled by arbitration if requested by Maker, the
Holder or any other party to the dispute (such as a guarantor); provided, both
                                                                --------      
Maker and the Holder must consent to a request for arbitration relating to an
obligation secured by real property.  The arbitration proceedings shall be held
in Seattle, Washington in accordance with the commercial arbitration rules of
the American Arbitration Association, and the United States Arbitration Act
(i.e., Title 9, U.S.C.).  There shall be one arbitrator who shall decide whether
an issue is arbitrable or whether any claim is barred by a statute of
limitations.  Judgment on the arbitration award may be entered in any court
having jurisdiction.  Commencement of a lawsuit shall not constitute a waiver of
the right of any party to request arbitration if the lawsuit is contested.  Each
party shall have the right before, during and after the commencement of any
arbitration proceeding to exercise any of the following remedies, in any order
or concurrently: (i) self-help remedies such as setoff or repossession; (ii)
judicial or nonjudicial foreclosure against real or personal property
collateral; and (iii) provisional remedies including injunction, appointment of
receiver, attachment, claim and delivery and replevin.  The exercise of any such
remedy shall not waive a party's right to request arbitration.  Nothing in this
paragraph shall limit in any way any right the Holder may have to foreclose the
Deed of Trust judicially as a mortgage, or nonjudicially pursuant to the power
of sale.

  14.  DISPUTED OBLIGATIONS.  ALL COMMUNICATIONS CONCERNING DISPUTED DEBTS AND

                                   ---------
                                        
                                  PREPAYMENT


  If the interest rate converts to the Fixed Rate the principal balance of this
Note may be prepaid in whole or in part, at any time provided (i) a prepayment
fee is paid as set forth below, (ii) each partial prepayment is in an amount of
$10,000 or more, and (iii) partial prepayments may be no more frequent than once
per month.  THE PREPAYMENT FEE SHALL BE DUE AND PAYABLE WHETHER THE PREPAYMENT
IS BY VOLUNTARY PREPAYMENT, OPERATION OF LAW, ACCELERATION OR OTHERWISE.  The
amount of the prepayment fee depends on the following:

  1.  The amount by which certain "REFERENCE RATES", as defined below, have
changed between the time this Note is prepaid and the date the interest rate
converts to the Fixed Rate.

  2.  A prepayment fee factor (see "PREPAYMENT FEE FACTOR SCHEDULE" below).

  3.  The amount of principal prepaid.

                         DEFINITION OF REFERENCE RATES

  The "REFERENCE RATE" used to represent interest rate levels shall be the bond
equivalent yield of the average U.S. Treasury Securities having maturities
equivalent to the remaining period to maturity of the Loan or the last day of
the Fixed Rate Period, as applicable, rounded upward to the nearest month.  The
"INITIAL REFERENCE RATE" shall be the Reference Rate assigned to the Loan by the
Holder at the time the interest rate converts to the Fixed Rate.  The "FINAL
REFERENCE RATE" shall be the Reference Rate assigned to the Loan by the Holder
at the time of the prepayment.

  The applicable Reference Rates shall be determined from the Federal Reserve
Statistical Release (Publication H.15) as displayed on Page 119 of the Dow Jones
Telerate Service (or such other page or service as may replace that page or
service for the purpose of displaying rates comparable to said U.S. Treasury
Securities).  If the publishing of the foregoing Statistical Release is ever
discontinued, the applicable Reference Rate shall be based on the publication by
the Board of Governors of the United States Federal Reserve System in
replacement thereof, or if none, the publication which in the Holder's
discretion most nearly corresponds.

                         CALCULATION OF PREPAYMENT FEE

  1.  If the Initial Reference Rate is less than or equal to the Final Reference
Rate, there is no prepayment fee.

  2.  If the Initial Reference Rate is greater than the Final Reference Rate,
the prepayment fee shall be equal to the difference between the Initial
Reference Rate and the Final Reference Rate (expressed as a decimal), multiplied
by the appropriate factor from the Prepayment Fee Factor Schedule, multiplied by
the principal amount of the Loan being prepaid.

                     EXAMPLE OF PREPAYMENT FEE CALCULATION

  An amortizing loan with remaining principal of $250,000 is fully prepaid with
twenty-four (24) months remaining until maturity.  An Initial Reference Rate of
9.000% was assigned to the loan at the time the loan was closed.  The Final
Reference Rate (as determined by the current 24-month U.S. Treasury Rate on Page
119 of Telerate) is 7.500%.  Rates therefore have dropped 1.500% since the loan
was closed and a prepayment fee applies.  A prepayment fee factor of 1.3% is
determined from Table 1 below and the prepayment fee is computed as follows:

 Prepayment Fee = (0.09 - 0.075) x (1.3) x ($250,000) = $4,875.00

     The Holder of this Note is not required to actually reinvest the prepaid
principal in any U.S. Government Treasury Securities, or otherwise prove its
actual losses, as a condition to receiving a prepayment fee as calculated above.
Maker agrees this prepayment fee is the bargained-for consideration to the
Holder for permitting prepayment and the above is not a liquidated damages
provision.  This prepayment fee provision is to be interpreted in a manner that
would make it enforceable to the fullest extent permitted by law, with any
portion of the fee that is unenforceable being stricken or otherwise changed to
cause the fee, as revised, to be enforced.

(the "Company") and _________ (the "Executive"), dated as of the 1st day of
January, 1997 (the "Start Date").

     The Board of Directors of the Company (the "Board"), has determined that it
is in the best interests of the Company and its shareholders to assure that the
Company will have the continued dedication of the Executive, notwithstanding the
possibility, threat or occurrence of a Change of Control (as defined in Section
2) of the Company.  The Board believes it is imperative to diminish the
inevitable distraction of the Executive by virtue of the personal uncertainties
and risks created by a pending or threatened Change of Control and to encourage
the Executive's full attention and dedication to the Company currently and in
the event of any threatened or pending Change of Control, and to provide the
Executive with compensation and benefits arrangements upon a Change of Control
which ensure that the compensation and benefits expectations of the Executive
will be satisfied and which are competitive with those of other corporations.
Therefore, in order to accomplish these objectives, the Board has caused the
Company to enter into this Agreement.

     NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

     1.  Certain Definitions.  (a)  The "Effective Date" shall mean the first
         -------------------                                                 
date during the Change of Control Period (as defined in Section 1(b)) on which a
Change of Control occurs.  Anything in this Agreement to the contrary
notwithstanding, if a Change of Control occurs and if the Executive's employment
with the Company is terminated prior to the date on which the Change of Control
occurs, and if it is reasonably demonstrated by the Executive that such
termination of employment (I) was at the request of a third party who has taken
steps reasonably calculated to effect the Change of Control or (ii) otherwise
arose in connection with or anticipation of the Change of Control, then for all
purposes of this Agreement the "Effective Date" shall mean the date immediately
prior to the date of such termination of employment.

     (b)  The "Change of Control Period" shall mean the period commencing on the
Start Date of this Agreement stated above and ending on the third anniversary of
such date; provided, however, that commencing on the date one year after the
Start Date, and on each annual anniversary of such date (such date and each
annual anniversary thereof shall be hereinafter referred to as the "Renewal
Date"), the Change of Control Period shall be automatically extended so as to
terminate three years from such Renewal Date, unless at least 60 days prior to
the Renewal Date the Company shall give notice to the Executive that the Change
of Control Period shall not be so extended.

     2.  Change of Control.  For the purpose of this Agreement, a "Change of
         -----------------                                                  
Control" shall mean:

for election by the Company's shareholders, was approved by a vote of at least a
majority of the directors then comprising the Incumbent Board shall be
considered as though such individual were a member or the Incumbent Board, but
excluding, for this purpose, any such individual whose initial assumption of
office occurs as a result of either an actual or threatened election contest (as
such terms are used in Rule 14a-11 of Regulation 14A promulgated under the
Securities Exchange Act of 1934, as amended (the "Exchange Act")) or other
actual or threatened solicitation of proxies or consents by or on behalf of a

     3.  Employment Period.  The Company hereby agrees to continue the Executive
         -----------------                                                      
in its employ, and the Executive hereby agrees to remain in the employ of the
Company, in accordance with the terms and provisions of this Agreement, for the
period commencing on the Effective Date and ending on the third anniversary of
such date (the "Employment Period"), in the capacity of Senior Vice President
and Chief Financial Officer.  The Company agrees that it will not take any
action, or make any inappropriate demands on the Executive or demands which may
be deemed to arbitrarily, unreasonably or unnecessarily interfere with the
performance of the services to be rendered by the Executive hereunder.

     4.  Terms of Employment.  (a) Duties.  (i) During the Employment Period,
         -------------------       ------                                    
(A) the Executive's reporting requirements, authority, duties and

the most significant of those held, exercised and assigned at any time during
the 90-day period immediately preceding the Effective Date and (B) the

          (ii) During the Employment Period, and excluding any periods of
vacation and sick leave to which the Executive is entitled, the Executive agrees
to devote reasonable attention and time during normal business hours to the
business and affairs of the Company and, to the extent necessary to discharge
the responsibilities assigned to the Executive hereunder, to use the Executive's
reasonable best efforts to perform faithfully and efficiently such
responsibilities. During the Employment Period it shall not be a violation of
this Agreement for the Executive to (A) serve on corporate, civic or charitable
boards or committees, (B) deliver lectures, fulfill speaking engagements or
teach at educational institutions and (C) manage personal investments, so long
as such activities do not significantly interfere with the performance of the
Executive's responsibilities as an employee of the Company in accordance with
this Agreement. It is expressly understood and agreed that to the extent that
any such activities have been conducted by the Executive prior to the Effective
Date, the continued conduct of such activities (or the conduct of activities
similar in nature and scope thereto) subsequent to the Effective Date shall not
thereafter be deemed to interfere with the performance of the Executive's
responsibilities to the Company.

     (b)  Compensation.  (i) Base Salary.  During the Employment Period, the
          ------------       -------------                                  
Executive shall receive an annual base salary ("Annual Base Salary"), which
shall be paid in equal installments on a monthly basis, at least equal to twelve
times the highest monthly base salary paid or payable to the Executive by the
Company and its affiliated companies in respect of the twelve-month period

                                      -4-

ordinary course of business to other peer executives of the Company and its
affiliated companies.  Any increase in Annual Base Salary shall not serve to
limit or reduce any other obligation to the Executive under this Agreement.
Annual Base Salary shall not be reduced after any such increase and the term
Annual Base Salary as utilized in this Agreement shall refer to Annual Base
Salary as so increased.  As used in this Agreement, the term "affiliated
companies" shall include any company controlled by, controlling or under common
control with the Company.

          (ii) Annual Bonus.  In addition to Annual Base Salary, the Executive 
               ------------

annual bonus (the "Annual Bonus") in cash at least equal to the average
annualized (for any fiscal year consisting of less than twelve full months or
with respect to which the Executive has been employed by the Company for less
than twelve full months) bonus paid or payable, including by reason of any
deferral, to the Executive by the Company and its affiliated companies in
respect of the three fiscal years immediately preceding the fiscal year in which
the Effective Date occurs (the "Recent Average Bonus"). Each such Annual Bonus
shall be paid no later than the end of the third month of the fiscal year next
following the fiscal year for which the Annual Bonus is awarded, unless the
Executive shall elect to defer the receipt of such Annual Bonus.

and retirement plans, practices, policies and programs applicable generally to

event shall such plans, practices, policies and programs provide the Executive
with incentive opportunities (measured with respect to both regular and special
incentive opportunities, to the extent, if any, that such distinction is
applicable), savings opportunities and retirement benefit opportunities, in each
case, less favorable, in the aggregate, than the most favorable of those
provided by the Company and its affiliated companies for the Executive under
such plans, practices, policies and programs as in effect at any time during the
90-day period immediately preceding the Effective Date or if more favorable to
the Executive, those provided generally at any time after the Effective Date to

companies (including, without limitation, medical, prescription, dental,
disability, salary continuance, employee life, group life, accidental death and
travel accident insurance plans and programs) to the extent applicable generally
to other peer executives of the Company and its affiliated companies, but in no
event shall such plans, practices, policies and programs provide the Executive
with benefits which are less favorable, in the aggregate, than the most
favorable of such plans, practices, policies and programs in effect for the

          (vi) Fringe Benefits.  During the Employment Period, the Executive 
               ---------------

     5.  Termination of Employment.  (a) Death or Disability.  The Executive's
         --------------------------      -------------------                  
employment shall terminate automatically upon the Executive's death during the
Employment Period.  If the Company determines in good faith that the Disability
of the Executive has occurred during the Employment Period (pursuant to the
definition of Disability set forth below), it may give to the Executive written
notice in accordance with Section 12(b) of its intention to terminate the
Executive's employment.  In such event, the Executive's employment with the
Company shall terminate effective on the 30th day after receipt of such notice
by the Executive (the "Disability Effective Date"), provided that, within the 30
days after such receipt, the Executive shall not have returned to full-time
performance of the Executive's duties.  For purposes of this Agreement,
"Disability" shall mean the absence of the Executive from the Executive's duties
with the Company on a full-time basis for 180 consecutive business days as a
result of incapacity due to mental or physical illness which is determined to be
total and permanent by a physician selected by the Company or its insurers and
acceptable to the Executive or the Executive's legal representative (such
agreement as to acceptability not to be withheld unreasonably).

     (b) Cause.  The Company may terminate the Executive's employment during the
         -----                                                                  
Employment Period for Cause.  For purposes of this Agreement, "Cause" shall mean
(i) a material breach by the Executive of the Executive's obligations under
Section 4(a) (other than as a result of incapacity due to physical or mental
illness) which is demonstrably willful and deliberate on the Executive's part,
which is committed in bad faith or without reasonable belief that such breach is
in the best interests of the Company and which is not remedied in a reasonable
period of time after receipt of written notice from the Company specifying such
breach or (ii) the conviction of the Executive of a felony involving moral
turpitude.

     (c) Good Reason.  The Executive's employment may be terminated during the
         -----------                                                          
Employment Period by the Executive for Good Reason.  For purposes of this
Agreement, "Good Reason" shall mean

          (i) the assignment to the Executive of any duties inconsistent in any
     respect with the Executive's position (including status, offices, titles
     and reporting requirements), authority, duties or responsibilities 
<PAGE>
 
                                      -6-

     as contemplated by Sections 3 and 4(a) or any other action by the Company
     which results in a diminution in such position, authority, duties or
     responsibilities, excluding for this purpose an isolated, insubstantial and
     inadvertent action not taken in bad faith and which is remedied by the
     Company promptly after receipt of notice thereof given by the Executive;

          (ii) any failure by the Company to comply with any of the provisions
     of Section 4(b), other than an isolated, insubstantial and inadvertent
     failure not occurring in bad faith and which is remedied by the Company
     promptly after receipt of notice thereof given by the Executive;

          (iii) the Company's requiring the Executive to be based at any office
     or location other than that described in Section 4(a)(i)(B);

          (iv) any purported termination by the Company of the Executive's
     employment otherwise than as expressly permitted by this Agreement; or

          (v) any failure by the Company to comply with and satisfy Section
     ll(c), provided that such successor has received at least ten days prior
     written notice from the Company or the Executive of the requirements of
     Section 11(c).

For purposes of this Section 5(c), any good faith determination of "Good Reason"
made by the Executive shall be conclusive.  Anything in this Agreement to the
contrary notwithstanding, a termination by the Executive for any reason during
the six month period immediately following the first anniversary of the Change
of Control Date shall be deemed to be a termination for Good Reason for all
purposes of this Agreement.

     (d) Notice of Termination.  Any termination by the Company for Cause or by
         ---------------------                                                 
the Executive for Good Reason shall be communicated by Notice of Termination to
the other party hereto given in accordance with Section 12(b).  For purposes of
this Agreement, a "Notice of Termination" means a written notice which (i)
indicates the specific termination provision in this Agreement relied upon, (ii)
to the extent applicable, sets forth in reasonable detail the facts and
circumstances claimed to provide a basis for term nation of the Executive's
employment under the provision so indicated and (iii) if the Date of Termination
(as defined below) is other than the date of receipt of such notice, specifies
the termination date (which date shall be not more than 15 days after the giving
of such notice).  The failure by the Executive or the Company to set forth in
the Notice of Termination any fact or circumstance which contributes to a
showing of Good Reason or Cause shall not waive any right of the Executive or
the Company hereunder or preclude the Executive or the Company from asserting
such fact or circumstance in enforcing the Executive's or the Company's rights
hereunder.

     (e) Date of Termination.  "Date of Termination" means (i) if the
         -------------------                                         
Executive's employment is terminated by the Company for Cause, or by the
Executive for Good Reason, the date of receipt of the Notice of Termination or
any later date specified therein, as the case may be, (ii) if the Executive's
employment is terminated by the Company other than for Cause or Disability, the
Date of Termination shall be the date on which the Company notifies the
Executive of such termination and (iii) if the Executive's employment is
terminated by reason of death or Disability, the Date of Termination shall be
the date of death of the Executive or the Disability Effective Date, as the case
may be.

     6.  Obligations of the Company upon Termination.  (a)  Good Reason; Other
         -------------------------------------------        ------------------
Than for Cause, Death or Disability.  If, during the Employment Period, the
- -----------------------------------                                        
Company shall terminate the Executive's employment other than for Cause or
Disability or the Executive shall terminate employment for Good Reason:
<PAGE>
 
                                      -7-

          (i) the Company shall pay to the Executive in a lump sum in cash
     within 30 days after the Date of Termination the aggregate of the following
     amounts:

               A. the sum of (1) the Executive's Annual Base Salary through the
          Date of Termination to the extent not theretofore paid, (2) the
          product of (x) the greater of (i) the Annual Bonus paid or payable,
          including by reason of any deferral, to the Executive (and annualized
          for any fiscal year consisting of less than twelve full months or for
          which the Executive has been employed for less than twelve full
          months) for the most recently completed fiscal year during the
          Employment Period, if any, and (ii) the Recent Average Bonus (such
          greater amount shall be hereinafter referred to as the "Highest Annual
          Bonus"), and (y) a fraction, the numerator of which is the number of
          days in the current fiscal year through the Date of Termination, and
          the denominator of which is 365 and (3) any compensation previously
          deferred by the Executive (together with any accrued interest or
          earnings thereon) and any accrued vacation pay, in each case to the
          extent not theretofore paid (the sum of the amounts described in
          clauses (1), (2) and (3) shall be hereinafter referred to as the
          "Accrued Obligations"); and

               B. the amount equal to the product of (1) three and (2) the sum
          of (x) the Executive's Annual Base Salary and (y) the Highest Annual
          Bonus; and

               C. a separate lump-sum supplemental retirement benefit equal to
          the difference between (1) the actuarial equivalent (utilizing for
          this purpose the actuarial assumptions utilized with respect to the
          ATL Ultrasound, Inc. Retirement Plan (or any successor plan thereto)
          (the "Retirement Plan") during the 90-day period immediately preceding
          the Effective Date) of the benefit payable under the Retirement Plan
          and any supplemental and/or excess retirement plan of the Company and
          its affiliated companies providing benefits for the Executive (the
          "SERP") which the Executive would receive if the Executive's
          employment continued at the compensation level provided for in
          Sections 4(b)(i) and 4(b)(ii) for the remainder of the Employment
          Period, assuming for this purpose that all accrued benefits are fully
          vested and that benefit accrual formulas are no less advantageous to
          the Executive than those in effect during the 90-day period
          immediately proceeding the Effective Date, and (2) the actuarial
          equivalent (utilizing for this purpose the actuarial assumptions
          utilized with respect to the Retirement Plan during the 90-day period
          immediately preceding the Effective Date) of the Executive's actual
          benefit (paid or payable), if any, under the Retirement Plan and the
          SERP; and

          (ii) for the remainder of the Employment Period, or such longer period
     as any plan, program, practice or policy may provide, the Company shall
     continue benefits to the Executive and/or the Executive's family at least
     equal to those which would have been provided to them in accordance with
     the plans, programs, practices and policies described in Section 4(b)(iv)
     and 4(b)(vi) if the Executive's employment had not been terminated in
     accordance with the most favorable plans, practices, programs or policies
     of the Company and its affiliated companies as in effect and applicable
     generally to other peer executives and their families during the 90-day
     period immediately preceding the Effective Date or, if more favorable to
     the Executive, as in effect generally at any time thereafter with respect
     to other peer executives of the Company and its affiliated companies and
     their families, provided, however, that if the Executive becomes reemployed
     with another employer and is eligible to receive medical or other welfare
     benefits under another employer provided
<PAGE>
 
                                      -8-

     plan, the medical and other welfare benefits described herein shall be
     secondary to those provided under such other plan during such applicable
     period of eligibility (such continuation of such benefits for the
     applicable period herein set forth shall be hereinafter referred to as
     "Welfare Benefit Continuation"). For purposes of determining eligibility of
     the Executive for retiree benefits pursuant to such plans, practices,
     programs and policies, the Executive shall be considered to have remained
     employed until the end of the Employment Period and to have retired on the
     last day of such period; provided, however, that the Executive shall be
     entitled to the more favorable of the retiree benefits in effect on the
     Date of Termination or the retiree benefits in effect on the date that
     would have been the last date of the Employment Period if the Executive had
     remained employed; and

          (iii) to the extent not theretofore paid or provided, the Company
     shall timely pay or provide to the Executive and/or the Executive's family
     any other amounts or benefits required to be paid or provided or which the
     Executive and/or the Executive's family is eligible to receive pursuant to
     this Agreement and under any plan, program, policy or practice or contract
     or agreement of the Company and its affiliated companies as in effect and
     applicable generally to other peer executives and their families during the
     90-day period immediately preceding the Effective Date or, if more
     favorable to the Executive, as in effect generally thereafter with respect
     to other peer executives of the Company and its affiliated companies and
     their families (such other amounts and benefits shall be hereinafter
     referred to as the "Other Benefits").

     (b) Death.  If the Executive's employment is terminated by reason of the
         -----                                                               
Executive's death during the Employment Period, this Agreement shall terminate
without further obligations to the Executive's legal representatives under this
Agreement, other than for payment of Accrued Obligations (which shall be paid to
the Executive's estate or beneficiary, as applicable, in a lump sum in cash
within 30 days of the Date of Termination) and the timely payment or provision
of the Welfare Benefit Continuation and Other Benefits.

     (c) Disability.  If the Executive's employment is terminated by reason of
         ----------                                                           
the Executive's Disability during the Employment Period, this Agreement shall
terminate without further obligations to the Executive, other than for payment
of Accrued Obligations (which shall be paid to the Executive in a lump sum in
cash within 30 days of the Date of Termination) and the timely payment or
provision of the Welfare Benefit Continuation and Other Benefits.

     (d) Cause; Other than for Good Reason.  If the Executive's employment shall
         ---------------------------------                                      
be terminated for Cause during the Employment Period, this Agreement shall
terminate without further obligations to the Executive other than the obligation
to pay to the Executive Annual Base Salary through the Date of Termination plus
the amount of any compensation previously deferred by the Executive, in each
case to the extent theretofore unpaid.  If the Executive terminates employment
during the Employment Period, other than for Good Reason, this Agreement shall
terminate without further obligations to the Executive, other than for Accrued
Obligations and the timely payment or provision of Other Benefits.  In such
case, all Accrued Obligations shall be paid to the Executive in a lump sum in
cash within 30 days of the Date of Termination.

     7.  Non-exclusivity of Rights.  Nothing in this Agreement shall prevent or
         ---------------------------                                           
limit the Executive's continuing or future participation in any plan, program,
policy or practice provided by the Company or any of its affiliated companies
and for which the Executive may qualify, nor shall anything herein limit or
otherwise affect such rights as the Executive may have under any contract or
agreement with the Company or any of its affiliated companies.  Amounts which
are vested benefits or which the Executive is otherwise entitled to receive
under any plan, policy, practice or program, of or any contract or agreement
<PAGE>
 
                                      -9-

with the Company or any of its affiliated companies at or subsequent to the Date
of Termination shall be payable in accordance with such plan, policy, practice
or program or contract or agreement except as explicitly modified by this
Agreement.

     8.  Full Settlement; Resolution of Disputes.  (a)  The Company's obligation
         ---------------------------------------                                
to make the payments provided for in this Agreement and otherwise to perform its
obligations hereunder shall not be affected by any set-off, counterclaim,
recoupment, defense or other claim, right or action which the Company may have
against the Executive or others.  In no event shall the Executive be obligated
to seek other employment or take any other action by way of mitigation of the
amounts payable to the Executive under any of the provisions of this Agreement
and, except as provided in Section 6(a)(ii), such amounts shall not be reduced
whether or not the Executive obtains other employment.  The Company agrees to
pay promptly upon invoice, to the full extent permitted by law, all legal fees
and expenses which the Executive may incur as a result of any contest
(regardless of the outcome thereof) by the Company, the Executive or others of
the validity or enforceability of, or liability under, any provision of this
Agreement or any guarantee of performance thereof (including as a result of any
contest by the Executive about the amount of any payment pursuant to this
Agreement).

     (b)  If there shall be any dispute between the Company and the Executive
(i) in the event of any termination of the Executive's employment by the
Company, whether such termination was for Cause, or (ii) in the event of any
termination of employment by the Executive, whether Good Reason existed, then,
unless and until there is a final, nonappealable judgment by a court of
competent jurisdiction declaring that such termination was for Cause or that the
determination by the Executive of the existence of Good Reason was not made in
good faith, the Company shall pay all amounts, and provide all benefits, to the
Executive and/or the Executive's family or other beneficiaries, as the case may
be, that the Company would be required to pay or provide pursuant to Section
6(a) as though such termination were by the Company without Cause or by the
Executive with Good Reason; provided, however, that the Company shall not be
required to pay any disputed amounts pursuant to this paragraph except upon
receipt of an undertaking by or on behalf of the Executive to repay all such
amounts to which the Executive is ultimately adjudged by such court not to be
entitled.

     9.  Certain Adjustments.  (a)  For purposes of this section, (i) A Payment
         -------------------                                                   
shall mean any payment or distribution in the nature of compensation to or for
the benefit of Executive, whether paid or payable pursuant to this Agreement or
otherwise (including the vesting of stock options, the lapse of restrictions on
restricted stock and any other events that result in a "payment in the nature of
compensation" within the meaning of Section 280G of the Internal Revenue Code of
1986, as amended (the "Code")); (ii) Agreement Payment shall mean a Payment paid
or payable pursuant to this Agreement (disregarding this Section 9); (iii) Net
After Tax Receipt shall mean the Present Value of a Payment net of all taxes
imposed on Executive with respect thereto under Sections 1 and 4999 of the Code
determined by applying the highest marginal rate under Section l of the Code
which applied to the Executive's taxable income for the immediately preceding
taxable year; (iv) "Present Value" shall mean such value determined in
accordance with Section 280G(d)(4) of the Code; and (v) "Reduced Amount" shall
mean the largest aggregate amount of Payments which is less than the sum of all
Payments and if paid to the Executive would result in aggregate Net After Tax
Receipts which are equal to or greater than the Net After Tax Receipts which
would result if the Executive were paid an amount equal to the sum of the
aggregate Payments.

     Anything in this Agreement to the contrary notwithstanding, in the event it
shall be determined that receipt of all Agreement Payments would subject
Executive to the excise tax under Section 4999 of the Code (together with any
<PAGE>
 
                                      -10-

interest or penalties imposed thereon, "Excise Tax") a determination shall be
made whether there is a "Reduced Amount".  If there is a Reduced Amount, the
aggregate Payments shall be reduced to such Reduced Amount.

     (b)  All determinations required to be made under this Section 9, including
whether there is a Reduced Amount, shall be made by KPMG Peat Marwick (the
"Accounting Firm") which shall provide detailed supporting calculations both to
the Company and the Executive within 15 business days of the receipt of notice
from the Executive that there has been a Payment, or such earlier time as is
requested by the Company.  In the event that the Accounting Firm is serving as
accountant or auditor for the individual, entity or group effecting the Change
of Control, the Executive may appoint another nationally recognized accounting
firm to make the determinations required hereunder (which accounting firm shall
then be referred to as the Accounting Firm hereunder).  All fees and expenses of
the Accounting Firm shall be borne solely by the Company.  If the Accounting
Firm determines that no Excise Tax is payable by the Executive, it shall furnish
the Executive with a written opinion that failure to report the Excise Tax on
the Executive's applicable federal income tax return would not result in the
imposition of a negligence or similar penalty.  If the Accounting Firm
determines that aggregate Payments should be reduced to the Reduced Amount, the
Company shall promptly give Executive notice to that effect and a copy of the
detailed calculation thereof.  As promptly as practicable following such
determination, the Company shall pay to or distribute for the benefit of
Executive such Agreement Payments as are then due to Executive under this
Agreement and shall promptly pay to or distribute for the benefit of Executive
in the future such Agreement Payments as become due to Executive under this
Agreement.  Any determination by the Accounting Firm shall be binding upon the
Company and the Executive.  While it is the intention of the Company and the
Executive to reduce the amounts payable or distributable to Executive hereunder
only if the aggregate Net After Tax Receipts to Executive would thereby be
increased, as a result of the uncertainty in the application of Section 4999 of
the Code at the time of the initial determination by Accounting firm hereunder,
it is possible that amounts will not have been paid or distributed by the
Company to or for the benefit of Executive pursuant to this Agreement which
should not have been so paid or distributed ("Overpayment") or that additional
amounts which will have not been paid or distributed by the Company to or for
the benefit of Executive pursuant to this Agreement could have been so paid or
distributed ("Underpayment"), in each case, consistent with the calculation of
the Reduced Amount hereunder.  In the event that Accounting Firm, based either
upon the assertion of a deficiency by the Internal Revenue Service against the
Company or Executive which Accounting Firm believes has a high probability of
success determines that an Overpayment has been made, any such Overpayment paid
or distributed by the Company to or for the benefit of Executive shall be
treated for all purposes as a loan to Executive which Executive shall repay to
the Company together with interest at the applicable federal rate provided for
in Section 7872(f)(2) of the Code; provided, however, that no such loan shall be
deemed to have been made and no amount shall be payable by Executive to the
Company if and to the extent such deemed loan and payment would not either
reduce the amount on which the Executive is subject to tax under Section 1 and
Section 4999 of the Code or generate a refund of such taxes.  In the event that
Accounting Firm, based upon controlling precedent or substantial authority,
determines that an Underpayment has occurred, any such Underpayment shall be
promptly paid by the Company to or for the benefit of the Executive together
with interest at the applicable federal rate provided for in Section 7872(f)t2)
of the Code.

     10.  Confidential Information.  The Executive shall hold in a fiduciary
          ------------------------                                          
capacity for the benefit of the Company all secret or confidential information,
knowledge or data relating to the Company or any of its affiliated companies,
and their respective businesses, which shall have been obtained by the Executive
during the Executive's employment by the Company or any of its affiliated
companies and which shall not be or become public knowledge (other than by acts
<PAGE>
 
                                      -11-

by the Executive or representatives of the Executive in violation of this
Agreement).  After termination of the Executive's employment with the Company,
the Executive shall not, without the prior written consent of the Company or as
may otherwise be required by law or legal process, communicate or divulge any
such information, knowledge or data to anyone other than the Company and those
designated by it.  In no event shall an asserted violation of the provisions of
this Section 10 constitute a basis for deferring or withholding any amounts
otherwise payable to the Executive under this Agreement.

     11.  Successors.  (a)  This Agreement is personal to the Executive and
          ----------                                                       
without the prior written consent of the Company shall not be assignable by the
Executive otherwise than by will or the laws of descent and distribution.  This
Agreement shall inure to the benefit of and be enforceable by the Executive's
legal representatives.

     (b)  This Agreement shall inure to the benefit of and be binding upon the
company and its successors and assigns.

     (c)  The Company will require any successor (whether direct or indirect, by
purchase, merger, consolidation or otherwise) to all or substantially all of the
business and/or assets of the Company to assume expressly and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform it if no such succession had taken place.  As used in
this Agreement, "Company" shall mean the Company as hereinbefore defined and any
successor to its business and/or assets as aforesaid which assumes and agrees to
perform this Agreement by operation of law, or otherwise.

     12.  Miscellaneous.  (a)  This Agreement shall be governed by and construed
          -------------                                                         
in accordance with the laws of the State of Washington, without reference to
principles of conflict of laws.  This captions of this Agreement are not part of
the provisions hereof and shall have no force or effect.  This Agreement may not
be amended or modified otherwise than by a written agreement executed by the
parties hereto or their respective successors and legal representatives.

     (b)  All notices and other communications hereunder shall be in writing and
shall be given by hand delivery to the other party or by registered or certified
mail, return receipt requested, postage prepaid, addressed as follows:

     Attention: General Counsel

or to such other address as either party shall have furnished to the other in
writing in accordance herewith.  Notice and communications shall be effective
when actually received by the addressee.

     (c)  The invalidity or unenforceability of any provision of this Agreement
shall not affect the validity or enforceability of any other provision of this
Agreement.

     (d)  The Company may withhold from any amounts payable under this Agreement
such Federal, state or local taxes as shall be required to be withheld pursuant
to any applicable law or regulation.

     (e)  The Executive's or the Company's failure to insist upon strict
compliance with any provision hereof or any other provision of this Agreement or
the failure to assert any right the Executive or the Company may have hereunder,
including, without limitation, the right of the Executive to terminate
employment for Good Reason pursuant to Section 5(c)(i)-(v), shall not be deemed
to be a waiver of such provision or right or any other provision or right of
this Agreement.

     (f)  The Executive and the Company acknowledge that, except as may
otherwise be provided under any other written agreement between the Executive
and the Company, the employment of the Executive by the Company is "at will"
and, prior to the Effective Date, may be terminated by either the Executive or
the Company at any time.  Moreover, if prior to the Effective Date, the
Executive's employment with the Company terminates, then the Executive shall
have no further rights under this Agreement.

     IN WITNESS WHEREOF, the Executive has hereunto set the Executive's hand
and, pursuant to the authorization from its Board of Directors, the Company has
caused these presents to be executed in its name on its behalf, all as of the
day and year first above written.
