NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
JUNE 30, 1997
(dollars in thousands, except share and per share data)
(unaudited)
- -------------------------------------------------------------------------------
NOTE 1.  GENERAL

The consolidated financial statements of Physio-Control International 
Corporation (the "Company") at June 30, 1997 and for the three and six month 
periods then ended are unaudited and reflect all adjustments (consisting only 
of normal recurring adjustments) which are, in the opinion of management, 
necessary for a fair presentation of the financial position and operating 
results for the interim period.  The consolidated financial statements should 
be read in conjunction with the Company's Annual Report on Form 10-K for the 
year ended December 31, 1996.  The results of operations for the three and 
six month periods ended June 30, 1997 are not necessarily indicative of the 
results for the entire fiscal year ending December 31, 1997.

During May 1997, the Company (previously a Delaware Corporation) was 
re-incorporated in the State of Washington.  Also in June 1997, a 
wholly-owned subsidiary of the Company, Physio-Control Corporation ("PCC") 
was re-incorporated in the State of Washington.  These actions were approved 
by the shareholders at the Annual Meeting held May 1, 1997.  See Part II, 
Item 4 included herein.

During July 1997, the Company formed a new wholly-owned subsidiary, 
Physio-Control Manufacturing Corporation, ("PCMC") which was incorporated as 
a Washington corporation.

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

EARNINGS PER SHARE
Net earnings per common and common equivalent share is computed using the
weighted average number of shares outstanding adjusted for the incremental
shares attributed to outstanding options to purchase common stock.  Fully
diluted net earnings per common and common equivalent share is not materially
different from primary net earnings per common and common equivalent share and
is therefore not presented.

RECLASSIFICATIONS
Certain amounts in the prior periods have been reclassified to conform with the
current period presentation.

NOTE 3.   INVENTORIES

Inventories consist of the following:
                                             JUNE 30, 1997   DECEMBER 31, 1996

NOTE 4.   BANK BORROWINGS
During June 1997, PCC refinanced its existing indebtedness and entered into a 
new $30.0 million revolving bank credit facility


                                       7
<PAGE>

("the Agreement") of which up to $5.0 million may be used for issuance of 
standby letters of credit.  The Agreement, which matures during May 2000, 
replaced an existing $30.0 million revolving bank credit agreement which was 
to expire during December 1998.  Interest on advances under the Agreement bear 
interest at the borrower's option, at either (i) the reference rate (the 
higher of the lender's prime rate or federal funds rate plus 1%) (ii) LIBOR 
plus 0.5% or (iii) quoted rate (rate quoted by lender and accepted by 
borrower plus 0.5%).  Such rates are subject to increase in the event that 
the Company does not meet the fixed charge coverage ratio as defined in the 
Agreement.

The Company is required to pay a commitment fee equal to 0.125% of the amount by
which the available credit exceeds the outstanding advances on a quarterly
basis. This rate is subject to increase in the event that the Company does not
meet the fixed charge coverage ratio as defined.

The revolving credit facility is secured by a first priority security interest
in and lien on all of the accounts receivable and inventories of PCC, (located
in the United States) and is guaranteed by the Company and PCMC.  The Agreement
includes various affirmative and negative financial covenants which require,
among other things, that the Company maintain a certain fixed charge coverage
ratio, debt to net worth ratios, as well as a minimum tangible net worth, as
defined in the Agreement.  As of June 30, 1997, the Company had $19.8 million
outstanding under the Agreement, including $0.6 million in letters of credit.

NOTE 5:   COMMITMENTS AND CONTINGENCIES

LITIGATION
The Company is party to certain legal actions arising in the ordinary course 
of its business.  The Company's estimates of these exposures are based 
primarily on historical claims experience.  The Company expects settlements 
related to these claims to be paid over the next several years.  The majority 
of the costs associated with defending and disposing of these suits are 
covered by insurance.

On November 13, 1995, the Company initiated litigation in Washington State Court
against Heartstream, Inc.  ("Heartstream"), a company formed to develop,
manufacture and market defibrillators, as well as certain individuals who were
formerly employed by the Company and who are founders of and employees of
Heartstream.  The Company's claims are based on its belief that Heartstream and
such individuals have, among other things, misappropriated certain of the
Company's intellectual property and that such individuals have breached
contractual obligations to the Company.  The Company received an answer to its
complaint from Heartstream and in its answer, Heartstream denies the Company's
claims and alleges certain counterclaims against the Company for, among other
things, monopolization of the industry and tortuous interference with business
opportunities.  While the Company believes it has meritorious defenses against
the suit, the ultimate resolution of the matter could result in a loss of up to
$10 million.  The parties are currently conducting discovery in this litigation
and a tentative trial date has been set for March 1998.

Additionally, during January 1997, Heartstream initiated litigation against 
the Company in U.S. District Court for the Western District of Washington 
alleging that the Company is infringing a Heartstream patent related to 
product self-test features.  The Company has filed an answer denying 
Heartstream's claims and alleging certain counterclaims against Heartstream 
for infringement of a Company self-test patent.  Discovery is in the initial 
stages in this litigation.

If the Company does not prevail in these litigations or otherwise successfully
resolve its claims, its ability to design and market certain future products may
be adversely affected.  In addition, if a court were to find in favor of
Heartstream on its claims, the Company could be liable for significant damages. 
In the opinion of management, the amount of ultimate liability with respect to
these actions will not materially affect the financial position of the Company.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

Management's Discussion and Analysis of Financial Condition and Results of 
Operations contains forward-looking statements that involve risks and 
uncertainties.  The Company's future results may differ significantly from 
the results discussed herein due to many factors, including, but not limited 
to, product demand, the effect of general economic conditions, the impact of 
competitive products and pricing, product development, commercialization and 
technological difficulties, U.S. and foreign regulatory requirements, the 
effects of accounting policies and financing requirements, and other such 
risks and factors.

RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED JUNE 30, 1997 AND 1996
The Company reported worldwide sales of $45.0 million during the second 
quarter of 1997, reflecting an increase of $2.1 million or 5% from the 
comparable 1996 quarter. International sales of $14.0 million were up 44% 
from the comparable 1996 period, due in part to a Russian shipment totaling 
$2.1 million.  Domestic sales during the current quarter aggregated $31.0 
million, down 7% from the comparable 1996 quarter. Worldwide equipment sales 
of $29.3 million increased slightly from the comparable 1996 quarter due to 
the large Russian shipment, partially offset by the decrease in domestic 
equipment sales.  Worldwide service revenue of $7.2 million increased 8% over 
the comparable prior year period, and supplies (disposable and accessories) 
revenue of $8.5 million increased 17% due to a strong demand for the 
Company's disposable products, primarily QUIK-COMBO-TM- electrodes.

Domestic sales decreased $2.2 million from the comparable 1996 quarter mainly 
due to lower sales in the out-of-hospital market, which had benefited from 
strong 1996 sales driven by the introduction of LIFEPAK-Registered 
Trademark-11 products.  Notwithstanding, the Company shipped orders totaling 
$1.9 million to Marquette Medical Systems as a result of the Companies' 
recent alliance announced during the first quarter of 1997.  Internationally, 
sales increased 44% from the prior year quarter due to the $2.1 million 
shipment discussed above as well as higher sales in the United Kingdom and 
France. 

During the second quarter of 1997, the Company reported worldwide product 
orders of $36.8 million, up $4.5 million or 14% from the comparable 1996 
quarter.  The increase in product orders is attributed to continued strong 
acceptance of the Company's automated external defibrillators (AEDs), 
specifically the new LIFEPAK 500 defibrillator, in both the US and 
international markets, as well as the $1.9 million shipments to Marquette 
Medical Systems.  Domestic and international product orders increased 12% and 
17%, respectively, over the comparable 1996 quarter. 

Gross profit of $23.1 million increased $0.8 million during the current 
quarter from the $22.2 million reported during the comparable 1996 period.  
As a percentage of sales, gross margin decreased to 51.2% from 51.7% during 
the comparable 1996 quarter.  The decrease in gross margin was driven 
primarily by aggressive pricing in Europe partly offset by a more favorable 
domestic product mix.

Research and development ("R&D") expenditures of $4.9 million increased 7%
during the current quarter from $4.6 million in the comparable 1996 period.  As
a percentage of sales, R&D expenses remained essentially unchanged at 11%.  R&D
expenditures increased over the prior year period due to the Company's
continuing commitment to develop new products as well as conduct ongoing
research for future products and technology. 

Sales and marketing expenditures of $10.3 million increased 19% from the
comparable 1996 quarter.  The increase resulted from enhanced sales and
marketing efforts worldwide as well as approximately $0.4 million in selling
expense associated with the Russian sale.

General and administrative expenditures of $2.6 million increased $0.1 
million from the comparable 1996 quarter.  Other expenses, consisting 
primarily of interest expense, totaled $0.6 million and remained consistent 
with the comparable 1996 quarter. Income tax expense of $1.6 million 
reflected an increase in the Company's effective tax rate from 34% in the 
comparable 1996 period to 35% during the current period.  As a result of the 
above factors, net income for the second quarter of 1997 was $3.0 million, a 
decrease of $0.9 million from the comparable 1996 quarter.

RESULTS OF OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30, 1997 AND 1996 The 
Company reported worldwide sales of $85.7 million during the six month period 
ended June 30, 1997, which were essentially unchanged from the comparable 
1996 period.  Domestic sales of $60.6 million were down $4.0 million, or 6% 
from the prior year period.  International sales of $25.1 million, however, 
were up 19% or $4.0 million from the prior year period due in part to the 
significant Russian shipment which included both equipment and accessory 
products. Worldwide equipment sales of $55.4 million decreased 4% during the 
current six month period while worldwide service and supplies revenue 
totaling $30.3 million increased 9% from the $27.7 million reported in 1996.  
The decrease in equipment sales from the prior six month period was due 
primarily to lower demand in the domestic hospital market as well as a 
decrease in LIFEPAK 11 defibrillator sales following the introduction of this 
product during 1996. This decrease is partly offset by the success of the 
LIFEPAK 500 products in the AED market. The increase in service and supplies 
revenue was due primarily to strong sales of QUIK-COMBO electrodes, as well 
as growth in the Company's installed base of customers.

During the six months ended June 30, 1997, worldwide product orders totaled 
$73.9 million, an increase of $6.0 million or 9% over the comparable prior 
year period. Domestic orders were up 6% while international orders increased 
15% and included the 1997 Russian order and strong performance in the United 
Kingdom.

Gross profit during the six months ended June 30, 1997 totaled $43.9 million, 
an increase of $0.4 million or 1% from the comparable prior year period.  As 
a percentage of sales, gross profit increased from 50.8% in the prior year 
period to 51.2% in the current six months, largely due to favorable domestic 
product sales mix,  partly offset by aggressive international pricing. 

R&D expenses for the six months ended June 30, 1997 were $10.1 million, an 
increase of $0.9 million or 10% over the comparable prior year period. As a 
percentage of sales, R&D expenses increased slightly from 11% in the 
comparable 1996 period to 12% during the current year period.   

Sales and marketing expenditures of $19.2 million during the current six 
month period increased $2.4 million, or 14% from the comparable 1996 period.  
The increase was due to costs incurred for sales and marketing efforts aimed 
at introducing the Company's new LIFEPAK 500 defibrillator during the first 
quarter of 1997, as well as a continued commitment of resources at developing 
the international marketplace and increasing international market share.  
Selling and marketing expenses in the current six month period also include 
$0.4 million in Russian selling expense as discussed above. As a percentage 
of sales, sales and marketing expenses increased from 20% during the prior 
year period to 22% during the current year period.

General and administrative expenditures of $4.6 million decreased 10%, or 
$0.5 million, from the comparable prior year period mainly due to no 
counterpart during 1997 to the 1996 bonus accrual.  As a percentage of sales, 
general and administrative expenses decreased from 6% during the comparable 
prior year period to 5% during the current year period.

Other expenses, consisting primarily of interest expense, totaled $1.3 
million, essentially unchanged from the prior year period. 

Income tax expense of $3.0 million reflected an increase in the Company's 
effective tax rate from 34% in the comparable 1996 period to 35% during the 
current six month period.

As a result of the above factors, net income for the six month period ended 
June 30, 1997 was $5.6 million, a decrease of $1.6 million, or 23% from the 
comparable 1996 period.

LIQUIDITY AND CAPITAL RESOURCES
Management assesses the Company's liquidity by its ability to generate cash 
to fund operations.  Significant factors in the management of liquidity are:  
funds provided or used by operations, capital expenditures, levels of 
accounts receivable, inventories, accounts payable, as well as adequate lines 
of credit.  

During the six months ended June 30, 1997, the Company used $0.4 million in cash
to finance operations.  The use of working capital funds was attributed to
increased inventories as well as higher accounts receivables resulting from an
increased sales volume during the month of June 1997.

Cash used in investing activities during the six months ended June 30, 1997 
totaled $2.9 million and related to capital expenditures.  Consistent with 
1996, the majority of current capital expenditures related to the final 
stages of implementation of the Company's new computer business system, which 
was completed during the first quarter of 1997.  Additional capital 
expenditures during the six month period ended June 30, 1997 related to 
purchases of research and engineering equipment and tooling for new products. 
 The Company does not have any capital commitments outside the ordinary 
course of business. The Company's principal working capital requirements are 
financing accounts receivable and inventories.  At June 30, 1997, the Company 
had net working capital of $56.6 million, consisting of accounts receivable 
of $41.3 million, inventories of $37.6 million, accounts payable of $11.5 
million and accrued liabilities of $16.4 million.

During June 1997, PCC refinanced its existing indebtedness and entered into a 
new $30.0 million revolving bank credit facility as discussed in Notes to 
Consolidated Financial Statements, Part 1, Item 1, included herein.  The 
Agreement, which matures during May 2000 offers a lower cost of  borrowing 
with reduced interest rates and affords the Company greater flexibility in 
cash management by consolidating the number of  banking institutions at which 
the Company consolidates cash balances. The Company is required to pay a 
commitment fee equal to 0.125% of the amount by which the available credit 
exceeds the outstanding advances on a quarterly basis. This rate is subject 
to increase in the event that the Company does not meet the fixed charge 
coverage ratio as defined in the Agreement.

The credit facility is secured by a first priority security interest in and lien
on all of the accounts receivable and inventories of PCC (located in the United
States) and is guaranteed by the Company and PCMC.  The credit facility includes
various affirmative and negative financial covenants which require, among other
things, that the Company maintain a certain fixed charge coverage ratio, debt to
net worth ratios, as well as a minimum tangible net worth, as defined in the
Agreement.  As of June 30, 1997 the Company had $19.8 million outstanding under
the Agreement, including $0.6 million in letters of credit.

In addition, the Company has subordinated notes payable to Eli Lilly and Company
totaling $2.5 million which originated in the acquisition of PCC and certain
foreign assets.  Notes with a principal balance totaling $1.5 million mature on
January 31, 2001 and bear interest at LIBOR plus 3.25% .  A note with a
principal balance of $1.0 million matures November 15, 1998 and bears interest
at LIBOR plus 3.0%.

The Company believes, based upon current levels of operations and anticipated
growth, that funds generated from operations and available borrowings under the
credit Agreement, will be sufficient over the next twelve months for the Company
to make anticipated capital expenditures and fund working capital requirements.

Approximately 29% of the Company's sales during the six months ended June 30,
1997 were to international customers and the Company expects that sales to
international customers will continue to represent a material portion of its
revenues.  Certain of the Company's international receivables are denominated in
foreign currencies and exchange rate fluctuations impact the carrying 


                                       11
<PAGE>

value of these receivables.  The Company has elected to hedge certain assets 
denominated in foreign currencies with the purchase of forward contracts. 
Historically, fluctuations in foreign currency exchange rates have not had a 
material effect on the Company's results of operations and, with certain 
hedging activities, the Company does not expect such fluctuations to be 
material in the foreseeable future.

    In furtherance and not in limitation of the powers conferred by statute,
the board of directors of the Corporation is expressly authorized to make,
alter, amend, change, add to or repeal the by-laws of the Corporation by the
affirmative vote of 70% of the total number of directors then in office.  Any

entitled to vote on such alteration or repeal, subject to ARTICLE IX hereof.

written ballot unless the by-laws of the Corporation so provide.  Subject to the
rights of any series of Preferred Stock, (i) any action required or permitted to
be taken by the shareholders of the Corporation must be effected at an annual or
special meeting of shareholders of the Corporation, (ii) special meetings of
shareholders of the Corporation may be called only by either the board of
directors pursuant to a resolution adopted by the affirmative vote of the

under specified circumstances, the number of directors which shall constitute
the Board of Directors of the Corporation shall be such number as shall from
time to time be fixed by resolution adopted by the affirmative vote of 70% of
the total number of directors then in office. The directors of the Corporation
shall be divided into three classes: Class I, Class II and Class III. 
Membership in such class shall be as nearly equal in number as possible.  The
term of office of the initial Class I directors shall expire at the annual
election of directors by the stockholders of the Corporation in 1996, the term
of office of the initial Class II directors shall expire at the annual election
of directors by the stockholders of the Corporation in 1997, and the term of
office of the initial Class III directors shall expire at the annual election of
directors by the stockholders of the Corporation in 1998, or thereafter when
their respective successors in each case are elected by the stockholders and
qualified, subject, however, to prior death, resignation, retirement,
disqualification or removal

from office for cause.  At each succeeding annual election of directors by 
the stockholders of the Corporation beginning in 1996, the directors chosen 
to succeed those whose terms then expire shall be identified as being of the 
same class as the directors they succeed and shall be elected for a term 
expiring at the third succeeding annual election of directors by the 
stockholders of the Corporation, or thereafter when their respective 
successors in each case are elected by the stockholders and qualified.  If 
the number of directors is changed, any increase or decrease shall be 
apportioned among the classes so as to maintain the number of directors in 
each class as nearly equal as possible, and any additional director of any 
class elected to fill a vacancy resulting from an increase in such class 
shall hold office for a term that shall coincide with the remaining term of 
that class, but in no case shall a decrease in the number of directors 
shorten the term of any incumbent director.

    SECTION C.  REMOVAL AND RESIGNATION.  A director may be removed by the
shareholders only at a special meeting called for the purpose of removing the
director and the meeting notice shall state that the purpose, or one of the
purposes, of the meeting is removal of the director.  A director may be removed
from office with cause only if the number of votes cast to remove the director
by holders of outstanding shares of capital stock of the Corporation entitled to
vote generally in the election of directors exceeds the number of votes cast not
to remove the director; provided, however, that if a director is elected by the
holders of one or more authorized classes or series of capital stock,, such
director or directors so elected may be removed without cause only by the vote
of the holders of the outstanding shares of that class or series entitled to
vote.  Any director may resign at any time upon written notice to the board of
directors, its chairperson, the president or secretary of the Corporation.

    SECTION D.  VACANCIES AND NEWLY CREATED DIRECTORSHIPS.  Subject to any
rights of the holders of any series of Preferred Stock to fill such newly
created directorships or vacancies, any newly created directorships resulting
from any increase in the authorized number of directors and any vacancies in the
board of directors resulting from death, resignation, disqualification, removal
or other cause shall, unless otherwise provided by law or by resolution approved
by the affirmative vote of 70% of the total number of directors then in office,
be filled only by resolution approved by the affirmative vote of 70% of the
total number of directors then in office, and any director so chosen shall hold
office until the next election of the class for which such director shall have
been chosen, and until his successor shall have been duly elected and qualified,
unless he shall resign, die, become disqualified or be removed for cause.

rights, options or warrants to purchase from the Corporation any shares of its
stock of any class or classes to run for such period of time, for such
consideration, upon such terms and conditions, and in such form as the board of

group as specified in the Act entitled to vote on such alteration, amendment or
repeal, as a separate voting group.

    promptly notify the Corporation in writing of any proceeding for which
    indemnification could be sought under this Article.  In addition,
    Indemnitee shall give the Corporation such information and cooperation as
    it may reasonably require and as shall be within Indemnitee's power.
         
    With respect to any such proceeding as to which Indemnitee has notified the
    Corporation:
    
         (a)  The Corporation will be entitled to participate therein at its
              own expense; and

              thereof, with counsel satisfactory to Indemnitee.  Indemnitee's
              consent to such counsel may not be unreasonably withheld.
              
         After notice from the Corporation to Indemnitee of its election to
    assume the defense, the Corporation will not be liable to Indemnitee under
    this Article for any legal 

<PAGE>

    or other Expenses subsequently incurred by Indemnitee in connection with
    such defense.  However, Indemnitee shall continue to have the right to 
    employ its counsel in such proceeding, at Indemnitee's expense; and if:
         
             (i)   The employment of counsel by Indemnitee has been authorized
                   by the Corporation;
         
             (ii)  Indemnitee shall have reasonably concluded that there may be
                   a conflict of interest between the Corporation and
                   Indemnitee in the conduct of such defense; or
              
             (iii) The Corporation shall not in fact have employed counsel
                   to assume the defense of such proceeding, 
              
    the fees and Expenses of Indemnitee's counsel shall be at the expense of
    the Corporation.
    
         The Corporation shall not be entitled to assume the defense of any
    proceeding brought by or on behalf of the Corporation or as to which
    Indemnitee shall reasonably have made the conclusion that a conflict of
    interest may exist between the Corporation and the Indemnitee in the
    conduct of the defense.
         
         SECTION E.2.   INFORMATION TO BE SUBMITTED AND METHOD OF DETERMINATION
    AND AUTHORIZATION OF INDEMNIFICATION.  For the purpose of pursuing rights
    to indemnification under this Article, the Indemnitee shall submit to the
    Board a sworn statement requesting indemnification and reasonable evidence
    of all amounts for which such indemnification is requested (together, the
    sworn statement and the evidence constitute an "Indemnification
    Statement").
         
         Submission of an Indemnification Statement to the Board shall create a
    presumption that the Indemnitee is entitled to indemnification hereunder,
    and the Corporation shall, within sixty (60) calendar days thereafter, make
    the payments requested in the Indemnification Statement to or for the
    benefit of the Indemnitee, unless: (1) within such sixty (60) calendar
    day period it shall be determined by the Corporation that the Indemnitee is
    not entitled to indemnification under this Article; (2) such determination
    shall be based upon clear and convincing evidence (sufficient to rebut the
    foregoing presumption); and (3) the Indemnitee shall receive notice in
    writing of such determination, which notice shall disclose with
    particularity the evidence upon which the determination is based.
         
         The foregoing determination may be made: (1) by the Board of Directors
    by majority vote of a quorum of Directors who are not at the time parties
    to the proceedings; (2) if a quorum cannot be obtained, by majority vote of
    a committee duly designated by the Board of Directors (in which
    designation, Directors who are parties may participate) consisting solely
    of two (2) or more Directors not at the time parties to the proceeding;

<PAGE>

    (3) by special legal counsel; or (4) by the shareholders as provided by
    Section 23B.08.550 of the Act.
         
         Any determination that the Indemnitee is not entitled to
    indemnification, and any failure to make the payments requested in the
    Indemnification Statement, shall be subject to judicial review by any court
    of competent jurisdiction.
         
         SECTION E.3    SPECIAL PROCEDURE REGARDING ADVANCE FOR EXPENSES.  An
    Indemnitee seeking payment of Expenses in advance of a final disposition of
    the proceeding must furnish the Corporation, as part of the Indemnification
    Statement:
         
              (a)  A written affirmation of the Indemnitee's good faith belief
                   that the Indemnitee has met the standard of conduct required
                   to be eligible for indemnification; and
              
              (b)  A written undertaking, constituting an unlimited general
                   obligation of the Indemnitee, to repay the advance if it is
                   ultimately determined that the Indemnitee did not meet the
                   required standard of conduct.
         
         Upon satisfaction of the foregoing, the Indemnitee shall have a
    contractual right to the payment of such Expenses.
         
         SECTION E.4    SETTLEMENT.  The Corporation is not liable to indemnify
    Indemnitee for any amounts paid in settlement of any proceeding without the
    Corporation's written consent.  The Corporation shall not settle any
    proceeding in any manner which would impose any penalty or limitation on
    Indemnitee without Indemnitee's written consent.  Neither the Corporation
    nor Indemnitee may unreasonably withhold its consent to a proposed
    settlement.
    
    SECTION F.     CONTRACT AND RELATED RIGHTS.

         SECTION F.1    CONTRACT RIGHTS.  The right of an Indemnitee to
    indemnification and advancement of Expenses is a contract right upon which
    the Indemnitee shall be presumed to have relied in determining to serve or
    to continue to serve in his or her capacity with the Corporation.  Such
    right shall continue as long as the Indemnitee shall be subject to any
    possible proceeding.  Any amendment to or repeal of this Article shall not
    adversely affect any right or protection of an Indemnitee with respect to
    any acts or omissions of such Indemnitee occurring prior to such amendment
    or repeal.
    
         SECTION F.2    OPTIONAL INSURANCE, CONTRACTS, AND FUNDING.  The
              Corporation may:
         
              (a)  Maintain insurance, at its expense, to protect itself and
                   any Indemnitee against any liability, whether or not the
                   Corporation 

<PAGE>

                   would have power to indemnify the individual against the
                   same liability under Section 23B.08.510 or .520 of the Act;

              (b)  Enter into contracts with any Indemnitee in furtherance of
                   this Article and consistent with the Act; and
         
              (c)  Create a trust fund, grant a security interest, or use other
                   means (including without limitation a letter of credit) to
                   ensure the payment of such amounts as may be necessary to
                   effect indemnification as provided in this Article.
         
         SECTION F.3    SEVERABILITY.  If any provision or application of this
    Article shall be invalid or unenforceable, the remainder of this Article
    and its remaining applications shall not be affected thereby, and shall
    continue in full force and effect.
         
         SECTION F.4    RIGHT OF INDEMNITEE TO BRING SUIT.  If (1) a claim
    under this Article for indemnification is not paid in full by the
    Corporation within sixty (60) calendar days after an Indemnification
    Statement has been received by the Corporation; or (2) a claim under this
    Article for advancement of Expenses is not paid in full by the Corporation
    within twenty (20) calendar days after a written claim has been received by
    the Corporation, then the Indemnitee may, but need not, at any time
    thereafter bring suit against the Corporation to recover the unpaid amount
    of the claim.  To the extent successful in whole or in part, the Indemnitee
    shall be entitled to also be paid the expense (to be proportionately
    prorated if the Indemnitee is only partially successful) of prosecuting
    such claim.  Neither (1) the failure of the Corporation (including its
    Board of Directors, its shareholders, or independent legal counsel) to have
    made a determination prior to the commencement of such proceeding that
    indemnification or reimbursement or advancement of Expenses to the
    Indemnitee is proper in the circumstances; nor (2) an actual determination
    by the Corporation (including its Board of Directors, its shareholders, or
    independent legal counsel) that the Indemnitee is not entitled to
    indemnification or to the reimbursement or advancement of Expenses, shall
    be a defense to the proceeding or create a presumption that the Indemnitee
    is not so entitled.
         
         SECTION F.5    NONEXCLUSIVITY OF RIGHTS.  The right to indemnification
    and the payment of Expenses incurred in defending a Proceeding in advance
    of its final disposition granted in this Article shall not be exclusive of
    any other right which any Indemnitee may have or hereafter acquire under
    the Act, any statute, provision of this Article or the Bylaws, agreement,
    vote of shareholders or disinterested directors, or otherwise.  The
    Corporation shall have the express right to grant additional indemnity
    without seeking further approval or satisfaction by the shareholders.  All
    applicable indemnity provisions and any applicable law shall be interpreted
    and applied so as to provide an Indemnitee with the broadest but
    nonduplicative indemnity to which he or she is entitled.

<PAGE>

    SECTION G.     CONTRIBUTION.  If the indemnification provided in Section B
of this Article is not available to be paid to Indemnitee for any reason other
than those set forth in subparagraphs (a), (b), and (c) of Section B of this
Article (for example, because indemnification is held to be against public
policy even though otherwise permitted under Section B) then in respect of any
proceeding in which the Corporation is jointly liable with Indemnitee (or would
be if joined in such proceeding), the Corporation shall contribute to the amount
of loss paid or payable by Indemnitee in such proportion as is appropriate to
reflect:
    
              The relative benefits received by the Corporation on the one hand
              and the Indemnitee on the other hand from the transaction from
              which such proceeding arose, and
         
              The relative fault of the Corporation on the one hand and the
              Indemnitee on the other hand in connection with the events which
              resulted in such loss, as well as any other relevant equitable
              consideration.
         
    The relative benefits received by and fault of the Corporation on the one
hand and the Indemnitee on the other shall be determined by a court of competent
jurisdiction (which may be the same court in which the proceeding took place)
with reference to, among other things, the parties' relative intent, knowledge,
access to information, and opportunity to correct or prevent the circumstances
resulting in such loss.  The Corporation agrees that it would not be just and
equitable if a contribution pursuant to this Article was determined by pro rata
allocation or any other method of allocation which does not take account of the
foregoing equitable considerations.
    
    SECTION H.     EXCEPTIONS. Any other provision herein to the contrary
notwithstanding, the Corporation shall not be obligated pursuant to the terms of
these Articles to indemnify or advance Expenses to Indemnitee with respect to
any proceeding.
    
         SECTION H.1    CLAIMS INITIATED BY INDEMNITEE.  Initiated or brought
    voluntarily by Indemnitee and not by way of defense, but such
    indemnification or advancement of Expenses may be provided by the
    Corporation in specific cases if the Board of Directors finds it to be
    appropriate.  Notwithstanding the foregoing, the Corporation shall provide
    indemnification including the advancement of Expenses with respect to
    Proceedings brought to establish or enforce a right to indemnification
    under these Articles or any other statute or law or as otherwise required
    under the statute.
         
         SECTION H.2    LACK OF GOOD FAITH.  Instituted by Indemnitee to
    enforce or interpret this Article, if a court of competent jurisdiction
    determines that each of the material assertions made by Indemnitee in such
    proceeding was not made in good faith or was frivolous.
         
         SECTION H.3    INSURED CLAIMS.  For which any of the Expenses or
    liabilities for indemnification is being sought have been paid directly to
    Indemnitee by an insurance carrier under a policy of officers' and
    directors' liability insurance maintained by the Corporation.

<PAGE>

         SECTION H.4    PROHIBITED BY LAW.  If the Corporation is prohibited by
    the Act or other applicable law as then in effect from paying such
    indemnification and/or advancement of Expenses.  For example, the
    Corporation and Indemnitee acknowledge that the Securities and Exchange
    Commission ("SEC") has taken the position that indemnification is not
    possible for liabilities arising under certain federal securities laws. 
    Indemnitee understands and acknowledges that the Corporation has undertaken
    or may be required in the future to undertake with the SEC to submit the
    question of indemnification to a court in certain circumstances for a
    determination of the Corporation's right to indemnify Indemnitee.
         
    SECTION I.     SUCCESSORS AND ASSIGNS.  All obligations of the Corporation
to indemnify any Director or Officer shall be binding upon all successors and
assigns of the Corporation (including any transferee of all or substantially all
of its assets and any successor by merger or otherwise by operation of law). 
The Corporation shall not effect any sale of substantially all of its assets,
merger, consolidation, or other reorganization, in which it is not the surviving
entity, unless the surviving entity agrees in writing to assume all such
obligations of the Corporation.

                                  RELEASE AGREEMENT
                                  -----------------

Gentlemen:

     Physio-Control International Corporation, a Delaware corporation 
("Parent"), and Physio-Control corporation, a Delaware corporation 
("Borrower"), have entered into financing arrangements with 
Creditanstalt-Bankverein, a bank organized under the laws of the Republic of 
Austria ("Creditanstalt"), as set forth in the Amended and Restated Credit 
Agreement dated as of December 15, 1995 (as the same has been amended and 
supplemented, the "Loan Agreement"), between the borrower and Creditanstalt, 
and the other Loan Documents (as defined in the Loan Agreement) (all of the 
foregoing, together with the Loan Agreement, collectively, the "Existing 
Agreements") pursuant to which Creditanstalt has made loans and advances to 
Borrower (the "Loans") and Creditanstalt has issued the letters of credit 
listed on EXHIBIT A hereto for the account of borrower (collectively, the 
"Creditanstalt Letters of Credit").

          1.   RELEASES.

               (a)  Subject to the terms and conditions contained herein 
(including but not limited to Section 5), Creditanstalt hereby releases, 
discharges and acquits each of Parent and Borrower from any and all 
liabilities and obligations they may have to Creditanstalt arising out of the 
Existing Agreements.  Anything to the contrary in this Agreement 
notwithstanding, any provision of any Existing Agreement that by the terms of 
the Existing Agreements survives the termination thereof shall not be 
affected by this Agreement.

               (b)  Creditanstalt hereby terminates and releases any and all 
security interests in, liens and mortgages upon, and pledges of, all 
properties and assets of Borrower, its subsidiaries and Parent (whether 
personal, real or mixed, tangible or intangible) heretofore granted, pledged, 
assigned to,


<PAGE>


or otherwise claimed by, Creditanstalt, pursuant to the Loan 
Agreement and the other Existing Agreements.

               (c)  Subject to the terms and conditions contained herein, 
each of Borrower and Parent, for and in consideration of the release above, 
hereby releases, discharges and acquits Creditanstalt and its successors and 
assigns from all liabilities and obligations to Borrower and Parent and their 
respective successors and assigns arising out of the Existing Agreements.

          2.   INDEMNIFICATION FOR RETURNED ITEMS.

          Notwithstanding anything to the contrary contained in Section 
1 above, Borrower agrees to indemnify Creditanstalt from and hold 
Creditanstalt harmless against all loss, cost, damage or expense which 
Creditanstalt may suffer or incur as a result of any non-payment, claim, 
refund or dishonor of any checks or other items which have been credited by 
Creditanstalt to the account of Borrower in calculating the amount payable to 
Creditanstalt on the date hereof pursuant to Section 5(c) of this Agreement, 
together with any reasonable expenses or other reasonable and customary 
charges incident thereto.

          3.   DELIVERIES BY CREDITANSTALT.

and delivered to Creditanstalt by Borrower duly marked "paid in full";

               (b)  Uniform Commercial Code releases and/or terminations in 
form acceptable for recording covering financing statements which have been 
filed by Creditanstalt against Borrower or Parent;

               (c)  trademark and patent releases or reassignments, 
reassigning, without representations and warranties, to Borrower and/or 
releasing the security interest of Creditanstalt in all trademarks, patents 
and related assets heretofore assigned by Borrower to Creditanstalt pursuant 
to the Existing Agreements;

               (d)  discharges or satisfactions of any mortgages or deeds of 
trust or similar real property instruments previously executed and delivered 
by Borrower or Parent in favor of Creditanstalt in form acceptable for 
recording; and

               (e)  any stock certificates and executed stock powers related 
thereto previously delivered to Creditanstalt by Borrower or Parent.


<PAGE>


          4.   TERMINATION OF LOCKBOXES.  Creditanstalt agrees to send 
written notification, upon request and at the expense of Borrower, to any 
bank or institution with which Creditanstalt has blocked accounts, lockbox 
accounts or other arrangements for the receipt or transfer to Creditanstalt 
of remittances or proceeds from customers of Borrower, to the effect that all 
such arrangements with Creditanstalt are terminated, and to the extent any 
such arrangements are in effect with Creditanstalt, such arrangements are 
hereby terminated.

          5.   CONDITIONS PRECEDENT.  The effectiveness of this Agreement, 
and of any termination statements or other similar release instruments 
delivered by Creditanstalt hereunder, are subject to and conditioned upon the 
receipt by Creditanstalt of:

               (a)  an original of this Agreement, duly executed by the 
parties hereto;

               (b)  the original of each Letter of Credit, marked 'CANCELED';

plus $4,385.00 per day for each additional day thereafter that such payment 
has not been made prior to such time.

          6.   FURTHER ASSURANCES.  Creditanstalt further agrees to furnish, 
at Borrower's expense, additional releases and/or termination statements and 
such other and further documents, instruments and agreements as may be 
reasonably requested by Borrower, in order to effect and evidence more fully 
the matters covered hereby.

          7.   COSTS AND EXPENSES.  Borrower and Parent agree to pay all 
costs and expenses, including without limitation, reasonable attorneys fees, 
in connection with the preparation, execution, delivery, filing, recording 
and administration of this Release Agreement and the performance of any other 
acts required to effect the release of any security granted to the 
undersigned under the Existing Agreements.  In addition, Parent and Borrower

to be payable in connection with the execution and delivery, filing or 
recording of this Release Agreement and the other instruments and documents

delay in paying or omitting to pay such taxes or fees.

          8.   GOVERNING LAW.  This Agreement shall be construed in 
accordance with and be governed by the laws of the State of

<PAGE>

New York (without giving effect to the conflict of law principles thereof).

          9.   COUNTERPARTS.  This Agreement may be executed in any number of 
counterparts each of which shall be deemed to be an original hereof and 
submissible into evidence and all of which together shall be deemed to be a 
single instrument.

                                        Very truly yours,

Agent irrevocable notice of such election, of which election Agent will 
promptly notify Banks.  On the Commencement Date, each Bank shall make 
available to Agent its respective Pro Rata Share of such requested LIBOR Rate 
Advance no later than 12:00 noon, Seattle time, on the specified borrowing 
date.  Whether or not any Bank fails to fund its Pro Rata Share of a LIBOR 
Rate Advance, each Bank shall only be obligated to disburse to Agent such 
Bank's Pro Rata Share of such requested LIBOR Rate Advance.  At the time that 
Agent is informed by any Bank of any change in the Assessment Rate or Reserve 
Adjustment, Agent shall notify Borrower of the change and of the impact on 
any LIBOR Rate Advances then outstanding.

    2.5  PROCEDURE FOR MULTICURRENCY ADVANCES.  Borrower may request an 
Advance in British Pounds Sterling, Canadian Dollars, French Francs, German 
Marks, Italian Lire, Dutch Guilders, Swedish Kroner, or Spanish Pesetas (each 
a "Multicurrency Advance"), up to the U.S. Dollar equivalent of the lesser of 
(a) U.S.$5,000,000, or (b) the Available Amounts, as determined by the 
Exchange Rate for each such currency, as determined on the date the interest 
rate for such Advance is determined, by delivering its borrowing notice to 
Agent, in the form of Exhibit 2 attached, 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 Interest Period requested.  Agent shall 
advise each Bank of a request for a Multicurrency Advance by 10:30 a.m., 
Seattle time, three Business Days prior to the date the Multicurrency Advance 
is to be made.  Each Bank shall make available to Agent its Pro Rata Share of 
such requested Multicurrency Advance to the account in the bank and country 
specified to each Bank by Agent, on the date the Advance is to be made.  
Multicurrency Advances shall be credited on the date of Advance to the 
account specified by Borrower.  Each Multicurrency Advance shall be in a 
minimum amount equivalent to U.S.$500,000.

                                 -7-

<PAGE>

    2.6  BANK FUNDING.  Agent shall have no obligation to fund any portion of 
an Advance which has not been funded by such time by the applicable Bank.  
If, however, a Bank does not fund its Pro Rata Share of a Multicurrency 
Advance in a timely manner, and Agent funds such Advance to Borrower before 
having received funding from such Bank, such Bank shall reimburse Agent for 
any overdraft charges and interest incurred by Agent on account of such late 
or failed funding.

    2.7  COMMITMENT FEES.  On the first Business Day of each April, July, 
October, and January, beginning July 1, 1997, Borrower shall pay:

         (A)  to Agent for the account of Banks, in arrears, to be applied in
    accordance with their respective Pro Rata Shares, a commitment fee equal to
    the Fee Margin multiplied by the difference between (a) $25,000,000, and
    (b) the sum of (i) the daily outstanding principal balance of the Revolving
    Loan (with Multicurrency Advances to be valued as the U.S. Dollar
    equivalent of such Multicurrency Advances, based on the Exchange Rate for
    each such Advance); and (ii) the daily aggregate outstanding principal
    amount of all Letters of Credit; and

         (B)  to Seafirst for its sole account, in arrears, a commitment fee
    equal to the Fee Margin multiplied by the difference between
    (a) $5,000,000, and (b) the daily outstanding principal balance of the
    Swing Line.


                                      ARTICLE 3
                                  LETTERS OF CREDIT

    3.1  ISSUANCE.  Upon Borrower's execution of Seafirst's then-standard 
form Application and Agreement for Standby Credit ("L/C Agreement(s)"), 
Seafirst shall issue on Borrower's behalf standby letters of credit ("Letters 
of Credit") until the Termination Date, up to the Available Amount, in 
amounts not to exceed $5,000,000 in the aggregate, and with tenors not to 
extend beyond the Termination Date.  If there is a draw under a Letter of 
Credit, Borrower shall on demand immediately reimburse Seafirst for the 
amount of the draw, together with interest on the amount drawn, from the date 
of draw until paid, at a floating rate equal to the Base Rate plus 3% per 
annum.  Seafirst shall in addition have all rights provided in the L/C 
Agreement executed with respect to such Letter of Credit.  Any default in the 
L/C Agreement shall be a Default.

    3.2  FEES.  Borrower shall pay to Seafirst in advance, for the account of 
Banks, upon issuance of each Letter of Credit, a nonreimbursable Issuance Fee 
equal to the greater of (a) a percentage per annum equal to the Fixed Rate 
Margin (as determined on the date of issuance) on the face amount of the 
Letter of Credit, or (b) $250.  Borrower shall additionally, on demand, pay 
the following administrative fees to Seafirst for its own account (i.e., not 
for the account of the other Banks):

    (A)  a fee of $100 for each Letter of Credit which is required to be 
issued on the same Business Day as application is made for such Letter of 
Credit by Borrower;

    (B)  a fee of $50 for each Letter of Credit, the application for which 
does not have a form of letter of credit attached thereto, or where such form 
needs substantial re-working prior to its issuance;

    (C)  a fee of $100 for each Letter of Credit to be confirmed, advised, or 
guaranteed by banks which are not a correspondent bank of Seafirst or with 
which Seafirst does not have other standing relationships (in each case as 
such categorization is reasonably determined by Seafirst);

    (D)  reimbursement to Seafirst of all fees and charges charged to 
Seafirst by any advising or confirming bank with regard to any Letter of 
Credit;

                                 -8-

<PAGE>

plus additional transaction fees according to Seafirst's then-outstanding 
standard fee schedule, as delivered to Borrower, on all drafts, transfers, 
extensions, and other transactions in regard to the Letters of Credit, and 
reimburse Seafirst for all out-of-pocket costs, legal fees, and expenses.

    3.3  YIELD INDEMNITY.  If any law or regulation imposes or increases any 
reserve, special deposit, or similar requirement against letters of credit 
issued by Seafirst or subjects Seafirst or any Bank to any tax, charge, fee, 
deduction, or withholding of any kind in regard to the Letters of Credit, 
Borrower shall promptly on demand indemnify Seafirst or such Bank for any 
such increased costs, taxes, or charges.  Seafirst or such Bank, as the case 
may be, shall provide documentation to Borrower of any such increased costs, 
taxes, or charges.

                                      ARTICLE 4
                                      SWING LINE

    4.1  DESCRIPTION OF FACILITY.  Seafirst shall make Swing Line Advances to 
Borrower, PROVIDED that (a) the aggregate amount of all outstanding Swing 
Line Advances shall not exceed $5,000,000, and (b) each Swing Line Advance 
shall mature and be repaid on the earlier of (i) the next Business Day after 
the date such Swing Line Advance is advanced or (ii) the Termination Date 
(the "Swing Line").  Each Swing Line Advance shall bear interest at the 
Quoted Rate (or Base Rate, whichever is lower) as determined on the date the 
Swing Line Advance is disbursed to or for the benefit of Borrower, with all 
principal and accrued interest to be repaid on the next Business Day; 
PROVIDED, however, that Borrower may elect to pay all accrued interest on 
Swing Line Advances quarterly, on the last Business Day of each March, June, 
September, and December, in which case the Fixed Rate Margin shall be 
increased by 4 basis points (0.04%) for all Swing Line Advances.

    4.2  PROCEDURE FOR SWING LINE ADVANCES.  In accordance with all terms and 
conditions of this Agreement, Borrower may borrow at the Quoted Rate (or Base 
Rate, whichever is lower) under the Swing Line on any Business Day.  Borrower 
shall give Agent irrevocable notice (written or oral) specifying the amount 
to be borrowed on or before 3:30 p.m., Seattle time, on the day that a Swing 
Line Advance is requested; all Swing Line Advances shall be discretionary to 
the extent notification by Borrower is given subsequent to that time.  Agent 
shall advise Seafirst of a request for a Swing Line Advance, and Seafirst 
shall make available to Borrower its Swing Line Advance by the end of the 
same Business Day.

                                      ARTICLE 5
                                  RISK PARTICIPATION

    Mellon agrees for the benefit of Seafirst that it hereby purchases a risk 
participation in the Letters of Credit and any unreimbursed Letter of Credit 
draws equal to Mellon's Pro Rata Share of the outstanding balance of Letters 
of Credit plus the aggregate unreimbursed Letter of Credit draws.  Upon the 
occurrence of a Default, Mellon shall fund to Seafirst, pursuant to this risk 
participation, Mellon's Pro Rata Share of the aggregate unreimbursed Letter 
of Credit draws.  Mellon shall have no interest in any principal, interest, 
fees, or expenses due to Seafirst with regard to the Swing Line.  Prior to 
its funding under this Article, Mellon shall have no interest in any 
principal, interest, fees, or expenses due to Seafirst with regard to Letters 
of Credit, except (a) those accruing after the date such participation is 
funded, (b) those fees payable under Subsection 2.7, and (c) as to Issuance 
Fees, Mellon's Pro Rata Share of the amount of such fees.  Mellon's purchase 
of such participations shall be evidenced by a certificate in the form of 
Exhibit 3 attached.

                                      ARTICLE 6
                                 COLLATERAL SECURITY

    6.1  COLLATERAL.  As security for the prompt satisfaction of all 
Obligations, Borrower hereby grants to Agent, as agent for Banks, a lien 
upon, and a security interest in, all of the following as described below 
wherever the same shall be located, whether now owned or hereafter acquired, 
together with all replacements therefor and proceeds (including, but without 
limitation, insurance proceeds) and products thereof, all of which shall be 
of first-lien priority:  all of Borrower's accounts, all of Borrower's 
inventory located in the United States, and all proceeds thereof (together 
the "Collateral").

    6.2  COLLATERAL AGENT.  To the extent required by this Agreement, Agent 
shall perfect all Collateral in its own name as agent for each Bank, 
according to its respective Pro Rata Share, and such agency shall be 
disclosed on any UCC filings.  Agent shall only be required to perfect upon 
those portions of the Collateral which can be perfected by the filing of a 
UCC1 financing statement.

    6.3  FINANCING STATEMENTS AND OTHER DOCUMENTS.

         Borrower shall:

         (a)  Join with Agent in executing such UCC financing statements
    (including amendments thereto and continuation statements thereof) and
    other documents, in form satisfactory to Agent and as Agent may reasonably
    specify, in order to perfect, or continue the perfection of, the rights of
    Banks in the Collateral, with the priority of security interest required by
    this Agreement;

         (b)  Pay, or reimburse Agent for paying, all costs and taxes of filing
    or recording the same in such public offices as Agent may reasonably
    designate; 

         (c)  Except as provided in Subsection (d), take such other steps as
    Agent may reasonably direct, including the noting of the Agent's lien on
    the Collateral and on any certificates of title therefor, as is necessary
    to perfect to Agent's satisfaction the interest of Agent, as agent for the
    Banks, in the Collateral; and

         (d)  Upon a Default and notice from Agent, deliver to Agent all
    Collateral which is deliverable.

    6.4  COSTS.  If a Default has occurred and is continuing, Banks, upon 
unanimous agreement, shall have the right, but not the obligation, to pay 
taxes, assessments, charges, claims, liens or encumbrances and to cause 
compliance with all applicable governmental requirements if Banks, upon 
unanimous consent, consider it necessary to protect their security or the 
prospects of repayment of the Obligations.  Such payments and expenses are 
repayable on demand with interest at a floating rate equal to the Base Rate 
plus 3% per annum.

    6.5  AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT.  Borrower hereby 
irrevocably constitutes and appoints Agent and any officer or agent thereof, 
with full power of substitution, effective upon the occurrence of and during 
the continuation of a Default, as its true and lawful attorney-in-fact with 
full irrevocable power and authority in the place and stead of Borrower and 
in the name of Borrower or in its own name, from time to time in accordance 
with this Agreement, for the purposes of exercising its rights as a secured 
creditor pursuant to this Agreement, to take any and all appropriate action 
and to execute any or all documents and instruments that may be necessary or 
desirable to accomplish such purposes.

    6.6  NEGATIVE PLEDGE.  So long as any amount is payable by Borrower under 
this Agreement, or any Bank is committed to make Advances or issue Letters of 
Credit under this Agreement, Borrower 

                                  -10-

<PAGE>

shall not allow any property of Borrower, Guarantor, or any Material 
Subsidiary, whether real or personal, tangible or intangible, to be 
transferred or encumbered, or to have any lien placed upon such property, 
except (a) sales of inventory in the ordinary course of business, (b) 
patents, or intellectual or proprietary property, (c) to secure the 
Obligations, or (d) as otherwise expressly permitted by Sections 12.2 or 12.3.

                                    ARTICLE 7
                                   GUARANTIES

    The Obligations shall be absolutely and unconditionally guaranteed by 
Guarantor and every Material Subsidiary of Guarantor, jointly and severally, 
in form satisfactory to Banks.  Borrower authorizes Agent to release to any 
present or future guarantor all information Agent possesses concerning 
Borrower or any loans, credits, or other financial accommodations made to 
Borrower by Agent or Banks.

                                      ARTICLE 8
                                INTEREST RATE OPTIONS

    8.1  INTEREST RATES AND PAYMENT DATE.  The Revolving Loan shall bear 
interest from the date of Advance on the unpaid principal balance outstanding 
from time to time at the Base Rate or Adjusted LIBOR Rate as selected by 
Borrower, and all accrued interest shall be payable in arrears on each 
Interest Payment Date.

    8.2  OPTION RESTRICTIONS.  Each Interest Period for LIBOR Rate Advances 
shall be one week or one, two, three, or six months.  In no event shall the 
Interest Period extend beyond the Termination Date.  The minimum amount of a 
LIBOR Rate Advance shall be $500,000, with additional increments of $100,000 
each permitted.

    8.3  PREPAYMENTS.  Borrower may prepay any Base Rate Advance on any 
Business Day without premium or penalty.  If Borrower prepays all or any 
portion of a LIBOR Rate Advance prior to the end of an Interest Period, there 
shall be due at the time of any such prepayment the Prepayment Fee, 
determined in accordance with Form 51-6325, which shall be attached as 
Exhibit 1 to this Agreement, and any such prepayment may only be made if in 
the amount of $100,000 or more.

    8.4  REVERSION TO BASE RATE.  The Revolving Loan shall bear interest at 
the Base Rate unless an Adjusted LIBOR Rate is specifically selected.  At the 
termination of any Interest Period, each LIBOR Rate Advance shall revert to a 
Base Rate Advance unless Borrower directs otherwise pursuant to Section 2.4.

    8.5  INABILITY TO PARTICIPATE IN MARKET.  If Agent or any Bank in good 
faith cannot participate in the Eurodollar market for legal or practical 
reasons, the Adjusted LIBOR Rate shall cease to be an interest rate option. 
Agent or such Bank shall notify Borrower if and when it again becomes legal 
or practical to participate in the Eurodollar market, at which time the 
Adjusted LIBOR Rate shall resume being an interest rate option.

    8.6  COSTS.  Borrower shall, as to LIBOR Rate Advances, reimburse Agent, 
for the account of Banks, for all costs, taxes, and expenses, and defend and 
hold Banks harmless for any liabilities, which Banks may incur as a 
consequence of any changes in the cost of participating in, or in the laws or 
regulations affecting, the Eurodollar market, including any additional 
reserve requirements, except to the extent such costs are already calculated 
into the Adjusted LIBOR Rate.  This covenant shall survive this Agreement and 
the repayment of the Revolving Loan.  Banks shall provide documentation to 
Borrower detailing the basis for any charges made pursuant to this Section.

                                   -11-

<PAGE>

    8.7  BASIS OF QUOTES.  Borrower acknowledges that Agent or Banks may or 
may not in any particular case actually match-fund a LIBOR Rate Advance.  
Whether the mechanism for setting a particular rate in fact represents the 
actual cost to Banks for any particular dollar or Eurodollar deposit or any 
LIBOR Rate Advance will depend upon how such Bank actually chooses to fund 
the LIBOR Rate Advance,  or any foreign exchange contract.  By electing an 
Adjusted LIBOR Rate, Borrower waives any right to object to Agent's means of 
calculating the Adjusted LIBOR Rate quote accepted by Borrower.

                                      ARTICLE 9
                                CONDITIONS OF LENDING

Sections 9.1 through 9.6, and their obligation to make subsequent Advances

terminated or released.

                                    -12-
<PAGE>

    9.9  COMPLIANCE.  No Default or other event which, upon notice or lapse 
of time or both would constitute a Default, shall have occurred and be 
continuing, or shall exist after giving effect to the Advance or the issuance

                                      ARTICLE 10
                            REPRESENTATIONS AND WARRANTIES

    To induce Banks to enter into this Agreement, Borrower represents, 
warrants, and covenants to Agent and Banks as follows:

    10.1 EXISTENCE.  Borrower is in good standing as a corporation under the 
laws of the state of Delaware, has the power, authority, and legal right to 
own and operate its property or lease the property it operates and to conduct 
its current business; and is qualified to do business and is in good standing 
in all other jurisdictions where the ownership, lease, or operation of its 
property or the conduct of its business requires such qualification.

    10.2 ENFORCEABILITY.  The Loan Documents, when executed and delivered by 
Borrower, shall be enforceable against Borrower in accordance with their 
respective terms.

    10.3 NO LEGAL BAR.  The execution, delivery, and performance by Borrower 
of the Loan Documents, and the use of the loan proceeds, shall not violate 
any existing law or regulation applicable to Borrower; any ruling applicable 
to Borrower of any court, arbitrator, or governmental agency or body of any 
kind; Borrower's organizational documents; any security issued by Borrower; 
or any mortgage, indenture, lease, contract, undertaking, or other agreement 
to which Borrower is a party or by which Borrower or any of its property may 
be bound.

    10.4 LIENS AND ENCUMBRANCES.  As of this date, Borrower and each Material 
Subsidiary has good and marketable title to its property free and clear of 
all security interests, liens, encumbrances, or rights of others, except as 
disclosed in writing to Banks on attached Schedule 12.2(a), and except for 
taxes which are not yet delinquent and for conditions, restrictions, 
easements, and rights of way of record which do not materially affect the use 
of any of Borrower's property.

    10.5 LITIGATION.  Except as disclosed in writing to Banks on attached 
Schedule 10.5, there is no threatened (to Borrower's knowledge) or pending 
litigation, investigation, arbitration, or administrative action which may 
materially adversely affect Borrower's business, property, operations, or 
financial condition.

    10.6 PAYMENT OF TAXES.  Borrower has filed or caused to be filed all tax 
returns when required to be filed; and has, to the best of its knowledge, 
paid all taxes, assessments, fees, licenses, excise taxes, franchise taxes, 
governmental liens, penalties, and other charges levied or assessed against 
Borrower or any of its property imposed on it by any governmental authority, 
agency, or instrumentality that are due and payable (other than those returns 
or payments of which the amount, enforceability, or validity are contested in 
good faith by appropriate proceedings and with respect to which adequate 
reserves in conformity with GAAP are provided on Borrower's books).

    10.7 EMPLOYEE BENEFIT PLAN.  Borrower is, to the best of its knowledge, 
in material compliance with the provisions of ERISA and the regulations and 
published interpretations thereunder.  Borrower has not engaged in any acts 
or omissions which would make Borrower liable to the Plan, to any of its 
participants, or to the Internal Revenue Service, under ERISA.

    10.8 MISREPRESENTATIONS.  No information, exhibits, data, or reports 
furnished by Borrower or Guarantor or delivered to Agent or Banks in 
connection with Borrower's application for credit misstates any material 
fact, or omits any fact necessary to make such information, exhibits, data, 
or reports not misleading.

                                 -13-

<PAGE>

    10.9  NO DEFAULT.  Borrower is not in default in any Loan Document, or in 
any material contract, agreement, or instrument to which it is a party.

    10.10 NO BURDENSOME RESTRICTIONS.  No contract or other instrument to 
which Borrower is a party, or order, award, or decree of any court, 
arbitrator, or governmental agency, materially impairs Borrower's ability to 
repay the Obligations.

    10.11 HAZARDOUS SUBSTANCES.  To the best of Borrower's knowledge after 
due and diligent inquiry, no hazardous or toxic waste or substances are being 
stored on any Real Property, other than in accordance with all applicable 
environmental laws and regulations, or as disclosed in writing to Banks at 
the closing of this Agreement; nor have any such waste or substances been 
stored or used in, on, under, over, or about the Real Property prior to or 
during Borrower's or any subsidiary's ownership, possession, or control of 
any of such Real Property, other than in accordance with all applicable 
environmental laws and regulations or as disclosed in writing to Banks at the 
closing of this Agreement.  Borrower agrees to provide written notice to 
Agent immediately upon Borrower becoming aware that the Real Property is 
being or has been contaminated with hazardous or toxic waste or substances.  
Borrower will not cause nor permit any activities on the Real Property which 
directly or indirectly would be likely to result in the Real Property or any 
other property becoming contaminated with hazardous or toxic waste or 
substances.

    10.12 MATERIAL SUBSIDIARIES.  As of the date of this Agreement no 
Material Subsidiaries exist other than as listed on attached Schedule 10.12.

    10.13 MARGIN STOCK.  Borrower is not engaged, nor shall it engage, 
principally or as one of its important activities, in the business of 
extending credit for the purpose of "purchasing" or "carrying" margin stock 
under Regulation U of the Board of Governors of the Federal Reserve System.  
Borrower shall not use any part of the proceeds of any Advance for any 
purpose which violates or is inconsistent with the provisions of Regulation 
G, T, U, or X of such Board of Governors, as the same may be amended, 
supplemented, or modified from time to time.

    10.14 MATERIAL ADVERSE CHANGE.  As of each request for an Advance or for 
issuance of a Letter of Credit, that no material adverse change has occurred 
in Borrower's or Guarantor's business, property, or financial condition since 
the end of Guarantor's 1996 fiscal year, as reported in Guarantor's audited 
financial statements, and at the time of such Advance, or at the time of 
issuance of such Letter of Credit.

                                      ARTICLE 11
                                AFFIRMATIVE COVENANTS

    So long as this Agreement shall remain in effect, or any liability exists 
under the Loan Documents, Borrower shall, as to Sections 11.1, and 11.6 
through 11.14 (and shall take any action necessary to assure that each 
Material Subsidiary shall); and Guarantor shall, as to Sections 11.2 through 
11.14:

    11.1  USE OF PROCEEDS.  Use the proceeds of the Revolving Loan and Swing 
Line for working capital, for acquisitions permitted under this Agreement,

agent, to take such action on their behalf under the provisions of this 
Agreement and to exercise all such powers as are expressly delegated to Agent 
by the terms of this Agreement, together with such other powers as are

consulting with Banks, a successor agent, and Agent shall remain in place 
until a new agent accepts such appointment.  Upon the acceptance of its 
appointment as successor agent hereunder, (a) such successor agent shall 
succeed to all the rights, powers, and duties of the retiring Agent, (b) the 
term "Agent" shall mean such successor agent, and (c) the retiring Agent's 
appointment, powers, and duties as Agent shall be terminated.  After any

taken or omitted to be taken by it while it was Agent under this Agreement.

    or Borrower's performance under any Loan Document, or inspecting the

rely, and shall be fully protected in relying upon, any note, writing, 
resolution, notice, consent, certificate, message, statement, order, or other 
document or conversation believed to have been authorized, genuine or 
correct, or signed, sent, or made by the proper Person, or upon advice and 
statements of counsel (including, without limitation, legal counsel to Agent 
or Borrower, and independent accountants and other experts selected by Agent).

    13.7 INSTRUCTIONS.  Agent shall be fully justified in failing or refusing 
to take any action under this Agreement or any other Loan Document as Agent 
deems appropriate, unless it shall first receive the consent of Majority 
Banks or shall first be indemnified to its satisfaction by all Banks, in 
accordance with their respective Pro Rata Share, against all liabilities and 
expenses which may be incurred by it or by reason of taking or continuing to 
take any such action.  Agent shall in all cases be fully protected in acting 
or in refraining from acting under this Agreement or any other Loan Document 
in accordance with the consent of Majority Banks, where required, and such 
request and any action taken or not taken to act pursuant thereto shall be 
binding upon all of the Banks and all future holders of any interest in the 
Obligations.

    13.8 NOTICE OF DEFAULT.  Agent shall not be deemed to have knowledge or 
notice of the occurrence of any Default unless Agent has actual knowledge or 
has received notice from one or more of the Banks or Borrower referring to 
this Agreement, describing such Default and stating in substance 

                                   -20-

<PAGE>

that such notice is a "notice of default."  In the event Agent receives such 
a notice or has actual knowledge of any Default, Agent shall give notice 
thereof to all of the Banks.

    13.9  REPRESENTATIONS.  None of Agent's Related Parties have made any 
representation or warranty to Banks, and no action taken by Agent after the 
date of this Agreement, including any review of Borrower's affairs, shall be 
deemed to constitute any representation or warranty by Agent to any of the 
Banks.

    13.10 INDEPENDENT CREDIT REVIEW.  Each Bank represents to Agent that it 
has, independently and without reliance upon Agent, and based upon such 
financial statements, documents and information as it has deemed appropriate, 
made its own appraisal of and investigation into the business, property, 
operations, and financial condition of Borrower and Guarantor and made its 
own decision to enter into this Agreement.  Each of the Banks also represents 
that it shall, independently and without reliance upon Agent, and based upon 
such financial statements, documents, and information as it shall deem 
appropriate at the time, continue to make its own credit analysis, 
appraisals, and decisions in taking or not taking action under this 
Agreement, and to make such investigation as it deems necessary to inform 
itself as to the business, property, operations, and financial condition of 
Borrower.  For purposes of determining compliance with the conditions 
specified in Article 9, each Bank that has executed this Agreement shall be 
deemed to have consented to, approved, or accepted, or to be satisfied with, 
each document or other matter either sent by Agent to such Bank for consent, 
approval, acceptance, or satisfaction, or required under said Article to be 
consented to or approved by or acceptable or satisfactory to such Bank, 
unless such Bank promptly provides Agent with notice to the contrary.

    13.11 INFORMATION.  Agent shall have no obligation, duty, or 
responsibility, either initially or on a continuing basis, to provide Banks 
with any credit or other information concerning the business, property, 
operations, or financial condition of Borrower or Guarantor which may come 
into possession of any of Agent's Related Parties.  Although Agent may 
furnish to Banks, upon request, copies of documents Agent has received 
pursuant to this Agreement, Agent assumes no responsibility as to the 
authenticity, validity, or enforceability of any such documents.

    13.12 INDEMNITY.  The Banks shall indemnify Agent, according to their 
respective Pro Rata Share, from and against any and all liabilities, 
obligations, losses, damages, penalties, actions, suits, judgments, 
reasonable costs and expenses, taxes, and disbursements of any kind or nature 
whatsoever (except to the extent they arise from Agent's gross negligence or 
willful misconduct) which may at any time be imposed on, incurred by, or 
asserted against any of Agent's Related Parties or in any way relating to or 
arising out of this Agreement, any other Loan Document, or any document 
contemplated by or referred to therein, any transaction contemplated thereby, 
or any action taken or omitted by Agent under or in connection with any of 
the foregoing.  Without limiting the foregoing, each Bank shall reimburse 
Agent, in accordance with such Bank's Pro Rata Share, for any costs or 
expenses incurred by Agent subsequent to the closing of this Agreement, 
including outside or in-house legal fees, which (a) are required to be 
reimbursed to Agent by Borrower under any of the Loan Documents, but are not 
so reimbursed, or (b) arise out of action taken by Agent at the unanimous 
consent of Banks in accordance with this Agreement.  This subsection shall 
survive the final payment of the Obligations and payment of all other amounts 
due under this Agreement or the other Loan Documents.

    13.13 SEPARATION OF CAPACITIES.  In its capacity as a lender that is one 
of the Banks, Seafirst shall have the same rights and powers hereunder as the 
other Banks and may exercise the same as though it were not Agent.  The term 
"Bank(s)" shall include Seafirst, in its individual capacity as a lender and 
not as an agent, unless the context otherwise indicates.  This Agreement 
shall not restrict in any way any Bank's ability to enter into other credit 
or banking facilities with Borrower or Guarantor, so long as such facility 
(a) does not violate any other provision of this Agreement and (b) is not 
secured by any of the Collateral; and the other Bank or Banks hereunder shall 
not have any rights or obligations as to any such facilities not provided by 
such Bank or Banks.

    deferred purchase price of property or services, or for the payment of rent
    under any lease, whether by acceleration or otherwise, which would permit
    such obligation to be declared due and payable prior to its stated
    maturity, with any such occurrence to be a Default immediately if the
    obligation concerned exceeds $500,000 or, if such occurrence is with regard
    to an obligation of $500,000 or less, if such default continues for 30 days
    after Borrower, Guarantor, or such Material Subsidiary, as the case may be,
    receives written notice thereof from the creditor so affected;

         (e)  GUARANTIES.  Any Guarantor or any Material Subsidiary revokes or
    attempts to revoke such guaranty, whether with respect to future
    transactions or outstanding Obligations, or otherwise breaches the terms
    and conditions of such guaranty, or violates any promise made pursuant to
    this Agreement, or any such guaranty is ruled to be invalid or
    unenforceable by any court of competent jurisdiction;

         (f)  CHANGE OF CONTROL.  Any Person (including any affiliated group of
    individuals and/or entities) shall acquire 25% or more of the outstanding
    voting stock of Guarantor; or Guarantor shall cease to own 100% of the
    outstanding voting stock of Borrower;

         (g)  AFFILIATES.  Any Material Subsidiary shall violate any of the
    covenants made by it in a certificate in the form of Exhibit 5 attached
    hereto, or any representation or warranty made or deemed made by it in such
    certificate is determined by any Bank to be false in any material respect
    when made, or any of the representations and warranties made by Guarantor
    in the addendum to this Agreement is determined by any Bank to be false in
    any material respect when made;

         (h)  LOSS, DESTRUCTION, OR CONDEMNATION OF PROPERTY.  A portion of
    Borrower's, Guarantor's, or any Material Subsidiary's property is affected
    by any uninsured loss, damage, destruction, theft, sale, or encumbrance
    other than created herein or is condemned, seized, or appropriated, the
    effect of which materially impairs Borrower's, Guarantor's, or such
    Material Subsidiary's financial condition or its ability to pay its debts
    as they come due;

                                        -22-

<PAGE>

         (i)  ATTACHMENT PROCEEDINGS AND INSOLVENCY.  Borrower, Guarantor, or
    any Material Subsidiary, or any of Borrower's, Guarantor's, or any such
    Material Subsidiary's property is affected by any:

              (I)  Judgment lien, execution, attachment, garnishment, general
         assignment for the benefit of creditors, sequestration, or forfeiture,
         to the extent Borrower's, Guarantor's, or such Material Subsidiary's
         financial condition or its ability to pay its debts as they come due
         is thereby materially impaired; or

              (II) Proceeding under the laws of any jurisdiction relating to
         receivership, insolvency, or bankruptcy, whether brought voluntarily
         or involuntarily by or against Borrower, Guarantor, or any Material
         Subsidiary, including, without limitation, any reorganization of
         assets, deferment or arrangement of debts, or any similar proceeding,
         and, if such proceeding is involuntarily brought against Borrower,
         Guarantor, or such Material Subsidiary, it is not dismissed within 60
         days;

         (j)  JUDGMENTS.  Final judgment on claims not covered by insurance
    which, together with other outstanding final judgments against Borrower,
    Guarantor, or any Material Subsidiary, exceeds $500,000, is rendered
    against Borrower, Guarantor, or any Material Subsidiary and is not
    discharged, vacated, or reversed, or its execution stayed pending appeal,
    within 60 days after entry, or is not discharged within 60 days after the
    expiration of such stay; or

         (k)  GOVERNMENT APPROVALS.  Any governmental approval, registration,
    or filing with any governmental authority, now or later required in
    connection with the performance by Borrower of its obligations under the
    Loan Documents, is revoked, withdrawn, or withheld, or fails to remain in
    full force and effect, except Borrower shall have 60 days after notice of
    any such event to take whatever action is necessary to obtain all necessary
    approvals, registrations, and filings.

    14.2 REMEDIES UPON DEFAULT.  If any Default occurs under Subsection 
14.1(i), the Banks' commitment to make Advances and Seafirst's commitment to 
make Swing Line Advances and issue new Letters of Credit shall immediately 
and automatically terminate (but Agent shall have no liability to any other 
Bank for, and any risk participations shall be effective as to, any Advances 
made by Agent or Letters of Credit issued by Seafirst prior to Agent 
receiving actual notice of such occurrence, absent Agent's willful misconduct 
or gross negligence), and all Obligations, including all accrued interest, 
shall immediately and automatically become due and payable, without 
presentment, demand, protest, or notice of any kind, all of which are hereby 
expressly waived by Borrower, and Agent may immediately, upon receiving 
notice of such an occurrence, exercise any or all of the following remedies 
for Default; and if any other Default occurs and is continuing, Agent, upon 
direction of Majority Banks, shall, by notice from Agent to Borrower:

         (a)  TERMINATE COMMITMENTS.  Terminate Banks' commitment to make
    Advances and Seafirst's commitment to make Swing Line Advances and issue
    new Letters of Credit;

         (b)  SUSPEND COMMITMENTS.  Refuse to make further Advances or Swing
    Line Advances or issue new Letters of Credit until any Default has been
    cured;

         (c)  ACCELERATE.  Declare all Obligations, including all accrued
    interest, to be immediately due and payable without presentment, demand,
    protest, or notice of any kind, all of which are hereby expressly waived by
    Borrower;

         (d)  COLLATERAL.  Proceed to realize on any or all Collateral by any
    available means; and/or

         (e)  ALL REMEDIES.  Pursue any other available legal and equitable
    remedies.

                                       -23-

<PAGE>

In addition, each Bank shall have the right to set off against, or place an 
administrative freeze upon, deposit accounts of Borrower at such Bank any 
amounts owing under the Obligations, including amounts in excess of such 
Bank's Pro Rata Share of the outstanding balance of the Obligations.  Any 
such amounts, and any other amounts received by any Bank on account of the 
Obligations, other than from Agent, shall be delivered to Agent to be 
distributed to each Bank in accordance with its respective Pro Rata Share; 
PROVIDED, however, that if all or any portion of such payment turned over 
from a Bank to Agent and distributed to each Bank is thereafter recovered by 
Borrower from such Bank, each Bank shall, in accordance with its respective 
Pro Rata Share, reimburse such other Bank for the amount so recovered.  All 
of Banks' and Agent's rights and remedies in all Loan Documents shall be 
cumulative and can be exercised separately or concurrently.  Borrower shall 
have no liability to any Bank with respect to any sum that Agent receives in 
accordance with this Agreement and fails to distribute to such Bank as 
required by this Agreement.

    14.3 DEFAULT INTEREST.  Upon Default, whether or not acceleration has 
occurred, all outstanding Advances shall, upon direction by Majority Banks to 
Agent, accrue interest at a floating rate per annum of 3.0% above the Base 
Rate, as it may vary from time to time.

                                      ARTICLE 15
                                    MISCELLANEOUS

    15.1 MANNER OF PAYMENTS.

         (a)  PAYMENTS ON NONBUSINESS DAYS.  Whenever any event is to occur or
    any payment is to be made under any Loan Document on any day other than a
    Business Day, such event shall occur or such payment shall be made on the
    next succeeding Business Day and such extension of time shall be included
    in computation of interest in connection with any such payment.

         (b)  PAYMENTS.  All payments and prepayments to be made by Borrower
    shall be made to Agent when due, at Agent's office as may be designated by
    Agent, without offsets or counterclaims for any amounts claimed by Borrower
    to be due from Agent or Banks, in the currency advanced, and in immediately
    available funds.

         (c)  TIMING OF PAYMENTS.  All payments and prepayments to be made by
    Borrower shall be made to Banks care of Agent, no later than 12:00 noon on
    the date when due (with payments received after 12:00 noon to be deemed
    received on the following Business Day), at Agent's office as may be
    designated by Agent, without offsets or counterclaims for any amounts
    claimed by Borrower to be due from any Bank, in the currency which was
    advanced to Borrower and in immediately available funds.  Notwithstanding
    the foregoing, payments due under the Swing Line may be made until 3:30
    p.m.

         (d)  APPLICATION OF PAYMENTS.  All payments made by Borrower shall be
    applied first against fees, expenses, and indemnities due; second, against
    interest due; and third, against principal, with Agent having the
    obligation, after a Default which is continuing, to apply any payments or
    collections received against the Obligations owing to the Banks in
    accordance with their respective Pro Rata Shares.  Except for payments made
    by Borrower to Agent for fees and indemnities due Agent, or payments made
    with regard to Swing Line Advances or Letters of Credit in which no Bank
    has been called upon to purchase a participation pursuant to Article 5, all
    payments made by Borrower shall be deemed to be made to Agent, as agent for
    Banks in accordance with each Bank's Pro Rata Share, and shall be
    distributed by Agent to Banks according to their respective Pro Rata Share;
    PROVIDED, that while Agent will make a good faith effort to make such
    remittances on the same Business Day as received, if payments are received
    from Borrower after 12:00 noon, and if it is not practicable for Agent to
    make same-day remittances to the Banks, then Agent shall not be obligated
    to remit funds to the Banks 

                                           -24-

<PAGE>

    until the next Business Day, along with interest at the Fed Funds Rate.  
    Any such payments which are received by a Bank shall be delivered 
    immediately by such Bank to Agent for distribution to Banks in accordance 
    with this subsection.

         (e)  RECORDING OF PAYMENTS.  Agent is authorized to record on a
    schedule or computer-generated statement the date and amount of each
    Advance and Swing Line Advance, all conversions between interest rate
    options, and all payments of principal and interest.  All such schedules or
    statements shall constitute PRIMA FACIE evidence of the accuracy of the
    information so recorded.

         (f)  ANTICIPATORY PAYMENTS.  Agent shall have the right (but not the
    obligation), if it reasonably anticipates receipt of payment from Borrower
    but has not actually received such payment, to forward payment to each Bank
    of its respective Pro Rata Share; PROVIDED, that if Borrower fails within
    one Business Day to make such payment, each Bank shall, immediately upon
    the demand of Agent, return such funds to Agent.

         (g)  PAYMENTS PURSUANT TO ADVANCES.  If an Advance is repaid by means
    of a new Advance in a like amount, Agent shall credit such new Advance
    directly to repayment of the maturing Advance, and no funds shall be
    transferred to or from Banks.

         (h)  MULTICURRENCY ADVANCES.  If a Multicurrency Advance is not repaid
    on the date when due, Borrower shall indemnify Agent and all Banks for all
    costs, expenses, and interest incurred by Agent and each such Bank in
    covering any foreign exchange contracts and hedges entered into by such
    parties with regard to such Multicurrency Advance.

    15.2 NOTICES.  Agent may make Advances and conversions between interest 
rates, and Seafirst shall make Swing Line Advances, based on telephonic, 
telex, and oral requests made by any Person whom Agent in good faith believes 
to be authorized to act on behalf of Borrower.  All other notices, demands, 
and other communications to be given pursuant to any of the Loan Documents 
shall be in writing and shall be deemed received the earlier of when actually 
received, or two days after being mailed, postage prepaid and addressed as 
follows, or as later designated in writing:

Attention:  Michael Collum              Attention:  Susan A. Dalton         

    15.3 DOCUMENTATION AND ADMINISTRATION EXPENSES.  Borrower shall pay, 
reimburse, and indemnify Agent and Banks for all of Agent's and Banks' 
reasonable costs and expenses, including, without limitation, all accounting, 
appraisal, and report preparation fees or expenses, all attorneys' fees 
(including the allocated cost of in-house counsel), legal expenses, and 
recording or filing fees, incurred in connection with the negotiation, 
preparation, execution, and administration of this Agreement and 

                               -25-

<PAGE>

all other Loan Documents, and all amendments, supplements, or modifications 
thereto, and the perfection of all security interests, liens, or encumbrances 
that may be granted to Banks; PROVIDED, that Borrower shall pay no more than 
$3,000 in legal fees for the initial documentation of the facilities 
evidenced by this Agreement. Borrower acknowledges that any legal counsel 
retained or employed by Agent or Banks acts solely on the Agent's and Banks' 
behalf and not on Borrower's behalf, despite Borrower's obligation to 
reimburse Agent and Banks for the cost of such legal counsel, and that 
Borrower has had sufficient opportunity to seek the advice of its own legal 
counsel with regard to this Agreement.

    15.4 COLLECTION EXPENSES.  The nonprevailing party shall, upon demand by 
the prevailing party, reimburse the prevailing party for all of its costs, 
expenses, and reasonable attorneys' fees (including the allocated cost of 
in-house counsel) incurred in connection with any controversy or claim 
between said parties relating to this Agreement or any of the other Loan 
Documents, or to an alleged tort arising out of the transactions evidenced by 
this Agreement, including those incurred in any action, bankruptcy 
proceeding, arbitration or other alternative dispute resolution proceeding, 
or appeal, or in the course of exercising any judicial or nonjudicial 
remedies.

    15.5 WAIVER.  No failure to exercise and no delay in exercising, on the 
part of Agent or Banks, any right, power, or privilege hereunder shall 
operate as a waiver thereof, nor shall any single or partial exercise of any 
right, power, or privilege hereunder preclude any other or further exercise 
thereof, or the exercise of any other right, power, or privilege.  Further, 
no waiver or indulgence by Agent or Banks of any Default shall constitute a 
waiver of Agent's and Banks' right to declare a subsequent similar failure or 
event to be a Default.

    15.6 ASSIGNMENT.  This Agreement is made expressly for the sole benefit 
of Borrower and for the protection of Agent and Banks and their respective 
successors and assigns.  The rights of Borrower hereunder shall not be 
assignable by operation of law or otherwise, without the prior written 
consent of Agent and Banks.  Upon any assignment, the assigning Bank shall 
pay Agent an assignment fee of $2,500.  Either Bank may at any time sell, 
assign, grant participations in, or otherwise transfer to any other financial 
institution (a "Participant") all or any part of its obligations under the 
Letters of Credit and its rights under this Agreement and the Loan Documents, 
with assignments only to be made with the consent of Borrower, which shall 
not be unreasonably withheld.  Participations may be sold without the consent 
of Borrower, PROVIDED that any voting rights of such participants shall be 
limited to matters of principal amount, interest rates, fees, payment dates, 
release of any Collateral or any guarantors, and extensions of the 
Termination Date or other maturities. Banks acknowledge and agree that any 
such disposition will not alter or affect such Bank's direct obligations 
under this Agreement and under the Letters of Credit and its participation 
therein.  Borrower acknowledges that any such Participant will become an 
owner PRO RATA of the Obligations, and Borrower waives any right it may have 
to setoff the Obligations against any claims or counterclaims it may have 
against the Bank selling such participation. Assignments by Banks, as opposed 
to participations, must be in minimum amounts of $5,000,000, and may only be 
made with the prior written consent of Borrower and Agent.  It is the 
intention of the parties that Borrower's obligation to pay or reimburse 
expenses will not be increased because of an assignment or the creation or 
transfer of a participation interest.  Notwithstanding anything in this 
Agreement to the contrary, Borrower shall not be required to pay or reimburse 
Agent or Banks for any fees, costs, or expenses, including attorneys' fees, 
relating to the creation or transfer of any assignment or participation 
interest.  Neither shall Borrower be required to pay or reimburse Agent or 
Banks for any documentation and administration expenses incurred by an 
assignee or Participant except to the extent that such expenses are in lieu 
of, and not in addition to, expenses incurred by Seafirst or Mellon.

    15.7 MERGER.  The rights and obligations set forth in this Agreement 
shall not merge into or be extinguished by any of the Loan Documents, but 
shall continue and remain valid and enforceable.  This Agreement and the 
other Loan Documents constitute Agent's and Banks' entire agreement with 
Borrower with regard to the Revolving Loan, the Swing Line, and the Letters 
of Credit, and supersede all prior writings and oral negotiations.  No oral 
or written representation, covenant, commitment, 

                                   -26-

<PAGE>

waiver, or promise of either Agent, any Bank or Borrower shall have any 
effect, whether made before or after the date of this Agreement, unless 
contained in this Agreement or another Loan Document, or in an amendment 
complying with Section 15.8.  ORAL AGREEMENTS OR ORAL COMMITMENTS TO LOAN 
MONEY, TO EXTEND CREDIT, OR TO FORBEAR FROM ENFORCING REPAYMENT OF A DEBT ARE 
NOT ENFORCEABLE UNDER WASHINGTON LAW.

    15.8  AMENDMENTS.  Any amendment or waiver of, or consent to any 
departure by Borrower from any provision of, this Agreement or any other Loan 
Document shall be in writing signed by each party to be bound thereby, and 
shall be effective only in the specific instance and for the specific purpose 
for which given.  Banks authorize Agent (i) to make the following amendments 
only upon the prior written consent of all Banks:

         (a)  increase the Credit Limit or the maximum amounts permitted for
    the Swing Line or issuance of Letters of Credit;

         (b)  extend the Termination Date;

         (c)  release any guaranty of the Obligations, or release any
    Collateral;

         (d)  reduce the principal, interest, or interest rate on the Revolving
    Loan or Swing Line, or the issuance fees charged with regard to Letters of
    Credit, or fees otherwise accruing under this Agreement, from that
    otherwise required under this Agreement; or

         (e)  postpone the date fixed for payment of any principal, interest,
    or fees;

and (ii) to waive, change, or release Borrower from any affirmative or 
negative covenant under this Agreement only upon the prior written consent of 
Majority Banks.  Seafirst shall not make Swing Line Advances after the 
occurrence of and during the continuance of a Default without the consent of 
all Banks.

    15.9  CONSTRUCTION.  Each term of this Agreement and each Loan Document 
shall be binding to the extent permitted by law and shall be governed by the 
laws of the State of Washington, excluding its conflict of laws rules.  If 
one or more of the provisions of this Agreement should be invalid, illegal, 
or unenforceable in any respect, the remaining provisions of this Agreement 
shall remain effective and enforceable.  If there is a conflict among the 
provisions of any Loan Documents, the provisions of this Agreement shall be 
controlling. The captions and organization of this Agreement are for 
convenience only, and shall not be construed to affect any provision of this 
Agreement.

    15.10 COUNTERPARTS.  This Agreement may be signed in any number of 
counterparts, each of which shall be an original, with the same effect as if 
the signatures to such counterparts were upon the same instrument.  This 
Agreement shall become effective when Agent shall have received counterparts 
of the Agreement signed by all of the parties to the Agreement.

                              CONSENT OF GUARANTOR

    The undersigned Guarantor acknowledges receipt of a copy of the above 
Agreement, consents to its contents, and agrees to comply with the covenants 
of Sections 11.2 through 11.14 thereof.  By submitting each of the financial 
statements required by Subsection 11.5(a) and 11.5(b), Guarantor is deemed to 
represent and warrant that: (a) such statement is complete and correct and 
fairly presents the consolidated financial condition of Guarantor as of the 
date of such statement; (b) such statement discloses all liabilities of 
Guarantor that are required to be reflected or reserved against under GAAP, 
whether liquidated or unliquidated, fixed or contingent; and (c) such 
statement has been prepared in accordance with GAAP.  As of the date of 
execution of this Agreement, there has been no adverse change in Guarantor's 
financial condition since preparation of the last such financial statements 
delivered to Banks which would materially impair Guarantor's ability to honor 
Guarantor's guaranty of the Obligations.  Guarantor hereby adopts and 
repeats, as to Guarantor, all representations and warranties made by Borrower 
as to Borrower in Article 10 of the above Agreement.

                               PREPAYMENT FEES

    If the principal balance of this note is prepaid in whole or in part, 
whether by voluntary prepayment, operation of law, acceleration or otherwise, 
a prepayment fee, in addition to any interest earned, will be immediately 
payable to the holder of this note.

    The amount of the prepayment fee depends on the following:

(1) The amount by which interest reference rates as defined below have changed
    between the time the loan is prepaid and either a) the time the loan was
    made for fixed rate loans, or b) the time the interest rate last changed
    (repriced) for variable rate loans.
(2) A prepayment fee factor (see "Prepayment Fee Factor Schedule" on reverse).
(3) The amount of principal prepaid.

If the proceeds from a CD or time deposit pledged to secure the loan are used 
to prepay the loan resulting in payment of an early withdrawal penalty for 
the CD, a prepayment fee will not also be charged under the loan.

           DEFINITION OF PREPAYMENT REFERENCE RATE FOR VARIABLE RATE LOANS

The "Prepayment Reference Rate" used to represent interest rate levels for 
variable rate loans shall be the index rate used to determine the rate on 
this loan having maturities equivalent to the remaining period to interest 
rate change date (repricing) of this loan rounded upward to the nearest 
month. The "Initial Prepayment Reference Rate" shall be the Prepayment 
Reference Rate at the time of last repricing and a new Initial Prepayment 
Reference Rate shall be assigned at each subsequent repricing.  The "Final 
Prepayment Reference Rate" shall be the Prepayment Reference Rate at the time 
of prepayment.

             DEFINITION OF PREPAYMENT REFERENCE RATE FOR FIXED RATE LOANS

The "Prepayment Reference Rate" used to represent interest rate levels on 
fixed rate loans shall be the bond equivalent yield of the average U.S. 
Treasury rate having maturities equivalent to the remaining period to 
maturity of this loan rounded upward to the nearest month. The "Initial 
Prepayment Reference Rate" shall be the Prepayment Reference Rate at the time 
the loan was made.  The "Final Prepayment Reference Rate" shall be the 
Prepayment Reference Rate at time of prepayment.

The Prepayment Reference Rate shall be interpolated from the yields 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 rates) on the day the loan was made 
(Initial Prepayment Reference Rate) or the day of prepayment (Final 
Prepayment Reference Rate).

                            CALCULATION OF PREPAYMENT FEE

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

If the Initial Prepayment Reference Rate is greater than the Final Prepayment
Reference Rate, the prepayment fee shall be equal to the difference between the
Initial and Final Prepayment Reference Rates (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.

<PAGE>

                        EXAMPLE OF PREPAYMENT FEE CALCULATION

VARIABLE RATE LOAN: A non-amortizing 6-month LIBOR based loan with principal 
of $250,000 is fully prepaid with 3 months remaining until next interest rate 
change date (repricing). An Initial Prepayment Reference Rate of 7.0% was 
assigned to the loan at last repricing.  The Final Prepayment Reference Rate 
(as determined by the 3-month LIBOR index) is 6.5%. Rates therefore have 
dropped 0.5% since last repricing and a prepayment fee applies.  A prepayment 
fee factor of 0.31 is determined from Table 3 below and the prepayment fee is 
computed as follows:

       Prepayment Fee = (0.07 - 0.065) x (0.31) x ($250,000) = $387.50

FIXED RATE LOAN: An amortizing loan with remaining principal of $250,000 is 
fully prepaid with 24 months remaining until maturity. An Initial Prepayment 
Reference Rate of 9.0% was assigned to the loan when the loan was made. The 
Final Prepayment Reference Rate (as determined by the current 24-month U.S. 
Treasury rate on Page 119 of Telerate) is 7.5%. Rates therefore have dropped 
1.5% since the loan was made 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

                          PREPAYMENT FEE FACTOR SCHEDULE

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

     NO VIOLATION. The execution and delivery of this Agreement will not 
     violate any law or agreement governing Grantor or to which Grantor is a
     party, and its certificate or articles of incorporation and bylaws do 
     not prohibit any term or condition of this Agreement.

     ENFORCEABILITY OF COLLATERAL. To the extent the Collateral consists of 
     accounts, chattel paper, or general intangibles, the Collateral is 
     enforceable in accordance with its terms, is genuine, and complies 
     with applicable laws concerning form, content and manner of preparation 
     and execution, and all persons appearing to be obligated on the 
     Collateral have authority and capacity to contract and are in fact 
     obligated as they appear to be on the Collateral.

     LOCATION OF THE COLLATERAL. Grantor, upon request of Lender, will 
     deliver to Lender in form satisfactory to Lender a schedule of real 
     properties and Collateral locations relating to Grantor's operations, 
     including without limitation the following: (a) all real property owned 
     or being purchased by Grantor; (b) all real property being rented or 
     leased by Grantor; (c) all storage facilities owned, rented, leased, or
     being used by Grantor; and (d) all other properties where Collateral is 
     or may be located. Except in the ordinary course of its business, 
     Grantor shall not remove the Collateral from its existing locations 
     without the prior written consent of Lender.

     REMOVAL OF COLLATERAL. Grantor shall keep the Collateral (or to the 
     extent the Collateral consists of intangible property such as accounts, 
     the records concerning the Collateral) at Grantor's address shown 
     above, or at such other locations as are acceptable to Lender. Except 
     in the ordinary course of its business, including the sales of 
     inventory, Grantor shall not remove the Collateral from its existing 
     locations without the prior written consent of Lender. To the extent 
     that the Collateral consists of vehicles, or other titled property, 
     Grantor shall not take or permit any action which would require 
     application for certificates of title for the vehicles outside the 
     State of Washington, without the prior written consent of Lender.

     TRANSACTIONS INVOLVING COLLATERAL. Except for inventory sold or accounts 
     collected in the ordinary course of Grantor's business, Grantor shall 
     not sell, offer to sell, or otherwise transfer or dispose of the 
     Collateral. Grantor shall not pledge, mortgage, encumber or otherwise 
     permit the Collateral to be subject to any lien, security interest, 
     encumbrance, or charge, other than the security interest provided for in 
     this Agreement, without the prior written consent of Lender. This 
     includes security interests even if junior in right to the security 
     interests granted under this Agreement. Unless waived by Lender, all 
     proceeds from any disposition of the Collateral (for whatever reason) 
     shall be held in trust for Lender and shall not be commingled with any 
     other funds; provided however, this requirement shall not constitute 
     consent by Lender to any sales or other disposition. Upon receipt, 
     Grantor shall immediately deliver any such proceeds to Lender.

     TITLE. Grantor represents and warrants to Lender that it holds good and 
     marketable title to the Collateral, free and clear of all liens and 
     encumbrances except for the lien of this Agreement. No financing 
     statement covering any of the Collateral is on file in any public office
     other than those which reflect the security interest created by this 
     Agreement or to which Lender has specifically consented. Grantor shall
     defend Lender's rights in the Collateral against the claims and demands
     of all other persons.

     COLLATERAL SCHEDULES AND LOCATIONS. Insofar as the Collateral consists 
     of inventory, Grantor shall deliver to Lender, as often as Lender shall 
     require, such list, descriptions, and designations of such Collateral as 
     Lender may require to identify the nature, extent, and location of such 
     Collateral. Such information shall be submitted for Grantor and each of 
     its subsidiaries or related companies.

     MAINTENANCE AND INSPECTION OF COLLATERAL. Grantor shall maintain all 
     tangible Collateral in good condition and repair. Grantor will not 
     commit or permit damage to or destruction of the Collateral or any part 
     of the Collateral. Lender and its designated representatives and agents 
     shall have the right at all reasonable times to examine, inspect, and 
     audit the Collateral wherever located. Grantor shall immediately notify 
     Lender of all cases involving the return, rejection, repossession, 
     loss or damage of or to any Collateral involving Collateral exceeding 
     $500,000.00 in the aggregate, of any request for credit or adjustment 
     or of any other dispute arising with respect to the Collateral involving
     Collateral exceeding $500,000.00 in the aggregate, and generally of all
     happenings and events affecting the Collateral or the value or the 
     amount of the Collateral.

     TAXES, ASSESSMENTS AND LIENS. Grantor will pay when due all taxes, 
     assessments and liens upon the Collateral, its use or operation, upon 
     this Agreement, upon any promissory note or notes evidencing the 
     Indebtedness, or upon any of the other Related Documents. Grantor may 
     withhold any such payment or may elect to contest any lien if Grantor is 
     in good faith conducting an appropriate proceeding to contest the 
     obligation to pay and so long as Lender's interest in the Collateral is 
     not jeopardized in Lender' sole opinion. If the Collateral is 
     subjected to a lien which is not discharged within (15) days, Grantor 
     shall deposit with Lender cash, a sufficient corporate surety bond or 
     other security satisfactory to Lender in an amount adequate to provide 
     for the discharge of the lien plus any interest, costs, attorneys' fees 
     or other charges that could accrue as a result of foreclosure or sale 
     of the Collateral. In any contest Grantor shall defend itself and Lender 
     and shall satisfy any final adverse judgment before enforcement against 
     the Collateral. Grantor shall name Lender as an additional obligee under 
     any surety bond furnished in the contest proceedings.

     COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS. Grantor shall comply promptly 
     with laws, ordinances, rules and regulations of all governmental 
     authorities, now or hereafter in effect, applicable to the ownership, 
     production, disposition, or use of the Collateral. Grantor may contest 
     in good faith any such law, ordinance or regulation and withhold 
     compliance during any proceeding, including appropriate appeals, so 
     long as Lenders's interest in the Collateral, in Lenders' opinion, is not 
     jeopardized.

     HAZARDOUS SUBSTANCES. Grantor represents and warrants that the Collateral 
     never has been, and never will be so long as this Agreement remains a 
     lien on the Collateral other than in compliance with applicable laws 
     and regulations, used for the generation, manufacture, storage, 
     transportation, treatment, disposal, release or threatened release of 
     any hazardous waste or substance, as those terms are defined in the 
     Comprehensive Environmental Response, Compensation, and Liability Act 
     of 1980, as amended, 42 U.S.C. Section 9601, et seq. ("CERCLA"), the 
     Superfund Amendments and Reauthorization Act of 1986, Pub. L No. 
     99-499 ("SARA"), the Hazardous Materials Transportation Act, 49 U.S.C. 
     Section 1801, et seq., the Resource Conservation and Recovery Act, 42 
     U.S.C. Section 6901, et seq., or other applicable state or Federal 
     laws, rules, or regulations, adopted pursuant to any of the foregoing. 
     The terms "hazardous waste" and "hazardous substance" shall also 
     include, without limitation, petroleum and petroleum by-products or any 
     fraction thereof and asbestos. The representations and warranties 
     contained herein are based on Grantor's due diligence in investigating 
     the Collateral for hazardous wastes and substances. Grantor hereby (a) 
     releases and waives any future claims against Lender for indemnity or 
     contribution in the event Grantor becomes liable for cleanup or other 
     costs under any such laws, and (b) agrees to indemnify and hold harmless 
     Lender against any and all claims and losses resulting from a breach of 
     this provision of this Agreement. This obligation to indemnify shall 
     survive the payment of the Indebtedness and the satisfaction of this 
     Agreement.

     MAINTENANCE OF CASUALTY INSURANCE. Grantor shall procure and maintain 
     all risks insurance, including without limitation fire, theft and 
     liability coverage together with such other insurance as Lender may 
     require with respect to the Collateral, in form, amounts, coverages and 
     basis reasonably acceptable to Lender and issued by a company or 
     companies reasonably acceptable to Lender. Grantor, upon request of 
     Lender, will deliver to Lender from time to time the policies or 
     certificates of insurance in form satisfactory to Lender, including 
     stipulations that coverages will not be cancelled or diminished without
     at least forty five (45) days' prior written notice to Lender and not 
     including any disclaimer of the insurer's liability for failure to give 
     such a notice. Each insurance policy also shall include an endorsement 
     providing that coverage in favor of Lender will not be impaired in any 
     way by any act, omission or default of Grantor or any other person. In 
     connection with all policies covering assets in which Lender holds or is 
     offered a security interest, Grantor will provide Lender with such loss 
     payable or other endorsements as Lender may require. If Grantor at any 
     time fails to obtain or maintain any insurance as required under this 
     Agreement, Lender may (but shall not be obligated to) obtain such 
     insurance as Lender deems appropriate, including if it so chooses 
     "single interest insurance," which will cover only Lender's interest in the
     Collateral.

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

     APPLICATION OF INSURANCE PROCEEDS. Grantor shall promptly notify Lender 
     of any loss or damage to the Collateral exceeding $500,000 in the 
     aggregate. Lender may make proof of loss if Grantor fails to do so 
     within fifteen (15) days of the casualty. All proceeds of any insurance 
     on the Collateral, including accrued proceeds thereon, shall be held by 
     Lender as part of the Collateral. If Lender consents to repair or 
     replacement of the damaged or destroyed Collateral, Lender shall, upon 
     satisfactory proof of expenditure, pay or reimburse Grantor for the 
     proceeds for the reasonable cost of repair or restoration. If Lender 
     does not consent to repair or replacement for the Collateral, Lender shall 
     retain a sufficient amount of the proceeds to pay all of the 
     Indebtedness, and shall pay the balance to Grantor. Any proceeds which 
     have not been disbursed within six (6) months after their receipt and 
     which Grantor has not committed to the repair or restoration of the 
     Collateral shall be used to prepay the Indebtedness.

     INSURANCE REPORTS. Grantor, upon request of Lender, shall furnish to 
     Lender reports on each existing policy of insurance showing such 
     information as Lender may reasonably request including the following: 
     (a) the name of the insurer; (b) the risks insured; (c) the amount of 
     the policy; (d) the property insured; (e) the current value on the basis 
     of which insurance has been obtained and the manner of determining that 
     value; and (f) the expiration date of the policy. In addition, Grantor 
     shall upon request by Lender (however not more often than annually) have 
     an independent appraiser satisfactory to Lender determine, as applicable,
     the cash value or replacement cost of the Collateral.

GRANTOR'S RIGHT TO POSSESSION. Until default, Grantor may have possession of 
the tangible personal property and beneficial use of all the Collateral and 
may use it in any lawful manner not inconsistent with this Agreement or the 
Related Documents, provided that Grantor's right to possession and beneficial 
use shall not apply to any Collateral where possession of the Collateral by 
Lender is required by law to perfect Lender's security interest in such 
Collateral. If Lender at any time has possession of any Collateral, whether 
before or after an Event of Default, Lender shall be deemed to have 
exercised reasonable care in the custody and preservation of the Collateral 
if Lender takes such action for the purpose as Grantor shall request or as 
Lender, in Lender's sole discretion, shall deem appropriate under the 
circumstances, but failure to honor any request by Grantor shall not of 
itself be deemed to be a failure to exercise reasonable care. Lender shall not 
be required to take any steps necessary to preserve any rights in the 
Collateral against prior parties, nor to protect, preserve or maintain any 
security interest given to secure the Indebtedness.

EXPENDITURES BY LENDER. If not discharged or paid when due, Lender may (but 
shall not be obligated to) discharge or pay any amounts required to be 
discharged or paid by Grantor under this Agreement, including without 
limitation all taxes, liens, security interests, encumbrances, and other 
claims, at any time levied or placed on the Collateral. Lender also may (but 
shall not be obligated to) pay all costs for insuring, maintaining and 
preserving the Collateral. All such expenditures incurred or paid by Lender 
for such purposes will then bear interest at the rate charged under the 
Indebtedness from the date incurred or paid by Lender to the date of 
repayment by Grantor. All such expenses shall become a part of the 
Indebtedness and at Lender's option, will (a) be payable on demand, (b) be 
added to the balance of the Indebtedness and be apportioned among and be 
payable with any installment payments to become due during either (i) the 
term of any applicable insurance policy or (ii) the remaining term of the 
Indebtedness or (c) be treated as a balloon payment which will be due and 
payable at the Indebtedness' maturity. This Agreement also will secure 
payment of these amounts. Such right shall be in addition to all other rights 
and remedies to which Lender may be entitled upon the occurrence of an Event 
of Default.

RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under this 
Agreement, at any time thereafter, Lender shall have all the rights of a 
secured party under the Washington Uniform Commercial Code. In addition and 
without limitation, Lender may exercise any one or more of the following 
rights and remedies:

     ACCELERATE INDEBTEDNESS. Lender may declare the entire Indebtedness, 
     including any prepayment penalty which Grantor would be required to pay, 
     immediately due and payable.

     ASSEMBLE COLLATERAL. Lender may require Grantor to deliver to Lender all 
     or any portion of the Collateral and any and all certificates of title and 
     other documents relating to the Collateral. Lender may require Grantor to 
     assemble the Collateral and make it available to Lender at a place to be 
     designated by Lender. Lender also shall have full power to enter upon 
     the property of Grantor to take possession of and remove the Collateral. 
     If the Collateral contains other goods not covered by this Agreement at
     the time of repossession, Grantor agrees Lender may take such other goods,
     provided that Lender makes reasonable efforts to return them to Grantor
     after repossession.

     SELL THE COLLATERAL. Lender shall have full power to sell, lease, 
     transfer, or otherwise deal with the Collateral or proceeds thereof in 
     its own name or that of Grantor. Lender may sell the Collateral at 
     public auction or private sale. Unless the Collateral threatens to decline 
     speedily in value or is of a type customarily sold on a recognized 
     market, Lender will give Grantor reasonable notice of the time after 
     which any private sale or any other intended disposition of the 
     Collateral is to be made. The requirements of reasonable notice shall be 
     met if such notice is given at least ten (10) days before the time of 
     the sale or disposition. All expenses relating to the disposition of the 
     Collateral, including without limitation the

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

     expenses of retaking, holding, insuring, preparing for sale and selling
     the Collateral, shall become a part of the Indebtedness secured by this
     Agreement and shall be payable on demand, with interest at the Note rate 
     from date of expenditure until repaid.

     APPOINT RECEIVER. To the extent permitted by applicable law, Lender 
     shall have the following rights and remedies regarding the appointment of 
     a receiver: (a) Lender may have a receiver appointed as a matter of 
     right, (b) the receiver may be an employee of Lender and may serve 
     without bond, and (c) all fees of the receiver and his or her attorney 
     shall become part of the Indebtedness secured by this Agreement and shall 
     be payable on demand, with interest at the Note rate from date of 
     expenditure until repaid.

     COLLECT REVENUES, APPLY ACCOUNTS. Lender, either itself or through a 
     receiver, may collect the payments, rents, income, and revenues from the 
     Collateral. Lender may at any time in its discretion transfer any 
     Collateral into its own name or that of its nominee and receive the 
     payments, rents, income, and revenue therefrom and hold the same as 
     security for the Indebtedness or apply it to payment of the Indebtedness 
     in such order of preference as Lender may determine. Insofar as the 
     Collateral consists of accounts, general intangibles, insurance 
     policies, instruments, chattel paper, choses in action, or similar 
     property, Lender may demand, collect, receipt for, settle, compromise, 
     adjust, sue for, foreclose, or realize on the Collateral as Lender may 
     determine, whether or not Indebtedness or Collateral is then due. For 
     these purposes, Lender may, on behalf of and in the name of Grantor, 
     receive, open and dispose of mail addressed to Grantor; change any 
     address to which mail and payments are to be sent; and endorse notes, 
     checks, drafts, money orders, documents of title, instruments and items 
     pertaining to payment, shipment, or storage of any Collateral. To 
     facilitate collection, Lender may notify account debtors and obligors on 
     any Collateral to make payments directly to Lender.

     OBTAIN DEFICIENCY. If Lender chooses to sell any or all of the 
     Collateral, Lender may obtain a judgment against Grantor for any 
     deficiency remaining on the Indebtedness due to Lender after 
     application of all amounts received from the exercise of the rights 
     provided in this Agreement. Grantor shall be liable for a deficiency even 
     if the transaction described in this subsection is a sale of accounts or 
     chattel paper.

     OTHER RIGHTS AND REMEDIES. Lender shall have all the rights and remedies 
     of a secured creditor under the provisions of the Uniform Commercial 
     Code, as may be amended from time to time. In addition, Lender shall 
     have and may exercise any or all other rights and remedies it may have 
     available at law, in equity or otherwise.

     CUMULATIVE REMEDIES. All of Lender's rights and remedies, whether 
     evidenced by this Agreement or the Related Documents or by any other 
     writing, shall be cumulative and may be exercised singularly or 
     concurrently. Election by Lender to pursue any remedy shall not exclude 
     pursuit of any other remedy, and an election to make expenditures or to 
     take action to perform an obligation of Grantor under this Agreement, 
     after Grantor's failure to perform, shall not affect Lender's right to 
     declare a default and to exercise its remedies. 

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of 
this Agreement.

     AMENDMENTS. This Agreement, together with any Related Documents, 
     constitutes the entire understanding and agreement of the parties as to

     amendment.

     be governed by and construed in accordance with the laws of the State of 
     Washington.

     ATTORNEY'S FEES; EXPENSES. Grantor agrees to pay upon demand all of 
     Lender's costs and expense, including reasonable attorneys' fees and 
     Lender's legal expenses, incurred in connection with the enforcement of

     attorney-in-fact, irrevocably, with full power of substitution to do the 
     following: (a) to demand, collect, receive, receipt for, sue and recover 
     all sums of money or other property which may now or hereafter become 
     due, owing or payable from the Collateral; (b) to execute, sign and 
     endorse any and all claims, instruments, receipts, checks, drafts or 
     warrants issued in payment for the Collateral; (c) to settle or 
     compromise any and all claims arising under the Collateral, and, in the 
     place and stead of Grantor, to execute and deliver its release and 
     settlement for the claim; and (d) to file any claim or claims or to take 
     any action or institute or take part in any proceedings, either in its 
     own name or in the name of Grantor, or otherwise, which in the 
     discretion of Lender may seem to be necessary or advisable. This power 
     is given as security for the Indebtedness, and the authority hereby 
     conferred is and shall be irrevocable and shall remain in full force and 
     effect until renounced by Lender.

     PREFERENCE PAYMENTS. Any monies Lender pays because of an asserted 
     preference claim in Borrower's bankruptcy will become a part of the 
     Indebtedness and, at Lender's option, shall be payable by Borrower as 
     provided above in the "EXPENDITURES BY LENDER" paragraph.

     SEVERABILITY. If a court of competent jurisdication finds any provision of
     this Agreement to be invalid or unenforceable as to any person or 
     circumstance, such finding shall not render that provision invalid or 
     unenforceable as to any other persons or circumstances. If feasible, any 
     such offending provision shall be deemed to be modified to be within the 
     limits of enforceability or validity; however, if the offending 
     provision cannot be so modified, it shall be stricken and all other 
     provisions of this Agreement in all other repsecces shall remain valid 
     and enforceable.

     SUCCESSOR INTERESTS. Subject to the limitations set forth above on 
     transfer of the Collateral, this Agreement shall be binding upon and 
     inure to the benefit of the parties, their successors and assigns.

     WAIVER. Lender shall not be deemed to have waived any rights under this 
     Agreement unless such waiver is given in writing and signed by Lender. No 
     delay or omission on the part of Lender in exercising any right shall  
     operate as a waiver of such right or any other right. A waiver by 
     Lender of a provision of this Agreement shall not prejudice or 
     constitute a waiver of Lender's right otherwise to demand strict 
     compliance with

     that provision or any other provision of this Agreement. No prior waiver 
     by Lender, nor any course of dealing between Lender and Grantor, shall 
     constitute a waiver of any of Lender's rights or of any Grantor's 
     obligations as to any future transactions. Whenever the consent of Lender 
     is required under this Agreement, the granting of such consent by Lender 
     in any instance shall not constitute continuing consent of subsequent 
     instances where such consent is required and all cases such consent may 
     be granted or withheld in the sole discretion of Lender.

     WAIVER OF CO-OBLIGOR'S RIGHTS. If more than one person is obligated for 
     the Indebtedness, Borrower irrevocably waivers, disclaims and 
     relinquishes all claims against such other person which Borrower has 
     or would otherwise have by virtue of payment of the Indebtedness or 
     any part thereof, specifically including but not limited to all rights 
     of indemnity, contribution or exoneration.

ADDITIONAL PROVISION. "LENDER" means (a) as to the granting clause of this 
Agreement, Bank of America National Trust and Savings Association, doing 
business as Seafirst Bank ("Seafirst"), as agent for itself and Mellon Bank, 
N.A. ""Mellon"), and means (b) as to all other provisions of this Agreement 
both Bank of America National Trust and Savings Association, doing business 
as Seafirst Bank, and Mellon Bank, N.A., and their respective successors and 
assigns. "INDEBTEDNESS" shall mean all the "Obligations", as such term is 
defined in the Credit Agreement dated as of June 3, 1997 (including all 
amendments thereto and restatements thereof, the "Credit Agreement"), between 
Borrower and Lender, including all renewals, modifications, and extensions 
thereof and all obligations of Grantor under this Agreement. Grantor 
acknowledges and agrees that all rights, powers, and privileges for either 
Seafirst or Mellon, in their respective individual capacities as Banks, 
may be exercised by Seafirst in its capacity as agent for the Banks; and the 
Grantor is neither permitted nor required to inquire as to Seafirst's 
authority to act for the Banks when its it purporting to act in its capacity 
as Agent. This provision does not hinder in any way each Bank's right to 
demand performance in its individual capacity. "COLLATERAL" shall have the 
meaning given to such term in the Credit Agreement. "EVENTS OF DEFAULT" shall 
mean each of the events which constitutes a "Default" under the terms of the 
Credit Agreement.

GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS COMMERCIAL 
SECURITY AGREEMENT, AND GRANTOR AGREES TO ITS TERMS. THIS AGREEMENT IS

     existing, and in good standing under the laws of the State of Delaware.

     AUTHORIZATION. The execution, delivery, and performance of this

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

     NO VIOLATION. The execution and delivery of this Agreement will not 
     violate any law or agreement governing Grantor or to which Grantor is a
     party, and its certificate or articles of incorporation and bylaws do 
     not prohibit any term or condition of this Agreement.

     ENFORCEABILITY OF COLLATERAL. To the extent the Collateral consists of 
     accounts, chattel paper, or general intangibles, the Collateral is 
     enforceable in accordance with its terms, is genuine, and complies 
     with applicable laws concerning form, content and manner of preparation 
     and execution, and all persons appearing to be obligated on the 
     Collateral have authority and capacity to contract and are in fact 
     obligated as they appear to be on the Collateral.

     LOCATION OF THE COLLATERAL. Grantor, upon request of Lender, will 
     deliver to Lender in form satisfactory to Lender a schedule of real 
     properties and Collateral locations relating to Grantor's operations, 
     including without limitation the following: (a) all real property owned 
     or being purchased by Grantor; (b) all real property being rented or 
     leased by Grantor; (c) all storage facilities owned, rented, leased, or
     being used by Grantor; and (d) all other properties where Collateral is 
     or may be located. Except in the ordinary course of its business, 
     Grantor shall not remove the Collateral from its existing locations 
     without the prior written consent of Lender.

     REMOVAL OF COLLATERAL. Grantor shall keep the Collateral (or to the 
     extent the Collateral consists of intangible property such as accounts, 
     the records concerning the Collateral) at Grantor's address shown 
     above, or at such other locations as are acceptable to Lender. Except 
     in the ordinary course of its business, including the sales of 
     inventory, Grantor shall not remove the Collateral from its existing 
     locations without the prior written consent of Lender. To the extent 
     that the Collateral consists of vehicles, or other titled property, 
     Grantor shall not take or permit any action which would require 
     application for certificates of title for the vehicles outside the 
     State of Washington, without the prior written consent of Lender.

     TRANSACTIONS INVOLVING COLLATERAL. Except for inventory sold or accounts 
     collected in the ordinary course of Grantor's business, Grantor shall 
     not sell, offer to sell, or otherwise transfer or dispose of the 
     Collateral. Grantor shall not pledge, mortgage, encumber or otherwise 
     permit the Collateral to be subject to any lien, security interest, 
     encumbrance, or charge, other than the security interest provided for in 
     this Agreement, without the prior written consent of Lender. This 
     includes security interests even if junior in right to the security 
     interests granted under this Agreement. Unless waived by Lender, all 
     proceeds from any disposition of the Collateral (for whatever reason) 
     shall be held in trust for Lender and shall not be commingled with any 
     other funds; provided however, this requirement shall not constitute 
     consent by Lender to any sales or other disposition. Upon receipt, 
     Grantor shall immediately deliver any such proceeds to Lender.

     TITLE. Grantor represents and warrants to Lender that it holds good and 
     marketable title to the Collateral, free and clear of all liens and 
     encumbrances except for the lien of this Agreement. No financing 
     statement covering any of the Collateral is on file in any public office
     other than those which reflect the security interest created by this 
     Agreement or to which Lender has specifically consented. Grantor shall
     defend Lender's rights in the Collateral against the claims and demands
     of all other persons.

     COLLATERAL SCHEDULES AND LOCATIONS. Insofar as the Collateral consists 
     of inventory, Grantor shall deliver to Lender, as often as Lender shall 
     require, such list, descriptions, and designations of such Collateral as 
     Lender may require to identify the nature, extent, and location of such 
     Collateral. Such information shall be submitted for Grantor and each of 
     its subsidiaries or related companies.

     MAINTENANCE AND INSPECTION OF COLLATERAL. Grantor shall maintain all 
     tangible Collateral in good condition and repair. Grantor will not 
     commit or permit damage to or destruction of the Collateral or any part 
     of the Collateral. Lender and its designated representatives and agents 
     shall have the right at all reasonable times to examine, inspect, and 
     audit the Collateral wherever located. Grantor shall immediately notify 
     Lender of all cases involving the return, rejection, repossession, 
     loss or damage of or to any Collateral involving Collateral exceeding 
     $500,000.00 in the aggregate, of any request for credit or adjustment 
     or of any other dispute arising with respect to the Collateral involving
     Collateral exceeding $500,000.00 in the aggregate, and generally of all
     happenings and events affecting the Collateral or the value or the 
     amount of the Collateral.

     TAXES, ASSESSMENTS AND LIENS. Grantor will pay when due all taxes, 
     assessments and liens upon the Collateral, its use or operation, upon 
     this Agreement, upon any promissory note or notes evidencing the 
     Indebtedness, or upon any of the other Related Documents. Grantor may 
     withhold any such payment or may elect to contest any lien if Grantor is 
     in good faith conducting an appropriate proceeding to contest the 
     obligation to pay and so long as Lender's interest in the Collateral is 
     not jeopardized in Lender' sole opinion. If the Collateral is 
     subjected to a lien which is not discharged within (15) days, Grantor 
     shall deposit with Lender cash, a sufficient corporate surety bond or 
     other security satisfactory to Lender in an amount adequate to provide 
     for the discharge of the lien plus any interest, costs, attorneys' fees 
     or other charges that could accrue as a result of foreclosure or sale 
     of the Collateral. In any contest Grantor shall defend itself and Lender 
     and shall satisfy any final adverse judgment before enforcement against 
     the Collateral. Grantor shall name Lender as an additional obligee under 
     any surety bond furnished in the contest proceedings.

     COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS. Grantor shall comply promptly 
     with laws, ordinances, rules and regulations of all governmental 
     authorities, now or hereafter in effect, applicable to the ownership, 
     production, disposition, or use of the Collateral. Grantor may contest 
     in good faith any such law, ordinance or regulation and withhold 
     compliance during any proceeding, including appropriate appeals, so 
     long as Lenders's interest in the Collateral, in Lenders' opinion, is not 
     jeopardized.

     HAZARDOUS SUBSTANCES. Grantor represents and warrants that the Collateral 
     never has been, and never will be so long as this Agreement remains a 
     lien on the Collateral other than in compliance with applicable laws 
     and regulations, used for the generation, manufacture, storage, 
     transportation, treatment, disposal, release or threatened release of 
     any hazardous waste or substance, as those terms are defined in the 
     Comprehensive Environmental Response, Compensation, and Liability Act 
     of 1980, as amended, 42 U.S.C. Section 9601, et seq. ("CERCLA"), the 
     Superfund Amendments and Reauthorization Act of 1986, Pub. L No. 
     99-499 ("SARA"), the Hazardous Materials Transportation Act, 49 U.S.C. 
     Section 1801, et seq., the Resource Conservation and Recovery Act, 42 
     U.S.C. Section 6901, et seq., or other applicable state or Federal 
     laws, rules, or regulations, adopted pursuant to any of the foregoing. 
     The terms "hazardous waste" and "hazardous substance" shall also 
     include, without limitation, petroleum and petroleum by-products or any 
     fraction thereof and asbestos. The representations and warranties 
     contained herein are based on Grantor's due diligence in investigating 
     the Collateral for hazardous wastes and substances. Grantor hereby (a) 
     releases and waives any future claims against Lender for indemnity or 
     contribution in the event Grantor becomes liable for cleanup or other 
     costs under any such laws, and (b) agrees to indemnify and hold harmless 
     Lender against any and all claims and losses resulting from a breach of 
     this provision of this Agreement. This obligation to indemnify shall 
     survive the payment of the Indebtedness and the satisfaction of this 
     Agreement.

     MAINTENANCE OF CASUALTY INSURANCE. Grantor shall procure and maintain 
     all risks insurance, including without limitation fire, theft and 
     liability coverage together with such other insurance as Lender may 
     require with respect to the Collateral, in form, amounts, coverages and 
     basis reasonably acceptable to Lender and issued by a company or 
     companies reasonably acceptable to Lender. Grantor, upon request of 
     Lender, will deliver to Lender from time to time the policies or 
     certificates of insurance in form satisfactory to Lender, including 
     stipulations that coverages will not be cancelled or diminished without
     at least forty five (45) days' prior written notice to Lender and not 
     including any disclaimer of the insurer's liability for failure to give 
     such a notice. Each insurance policy also shall include an endorsement 
     providing that coverage in favor of Lender will not be impaired in any 
     way by any act, omission or default of Grantor or any other person. In 
     connection with all policies covering assets in which Lender holds or is 
     offered a security interest, Grantor will provide Lender with such loss 
     payable or other endorsements as Lender may require. If Grantor at any 
     time fails to obtain or maintain any insurance as required under this 
     Agreement, Lender may (but shall not be obligated to) obtain such 
     insurance as Lender deems appropriate, including if it so chooses 
     "single interest insurance," which will cover only Lender's interest in the
     Collateral.

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

     APPLICATION OF INSURANCE PROCEEDS. Grantor shall promptly notify Lender 
     of any loss or damage to the Collateral exceeding $500,000 in the 
     aggregate. Lender may make proof of loss if Grantor fails to do so 
     within fifteen (15) days of the casualty. All proceeds of any insurance 
     on the Collateral, including accrued proceeds thereon, shall be held by 
     Lender as part of the Collateral. If Lender consents to repair or 
     replacement of the damaged or destroyed Collateral, Lender shall, upon 
     satisfactory proof of expenditure, pay or reimburse Grantor for the 
     proceeds for the reasonable cost of repair or restoration. If Lender 
     does not consent to repair or replacement for the Collateral, Lender shall 
     retain a sufficient amount of the proceeds to pay all of the 
     Indebtedness, and shall pay the balance to Grantor. Any proceeds which 
     have not been disbursed within six (6) months after their receipt and 
     which Grantor has not committed to the repair or restoration of the 
     Collateral shall be used to prepay the Indebtedness.

     INSURANCE REPORTS. Grantor, upon request of Lender, shall furnish to 
     Lender reports on each existing policy of insurance showing such 
     information as Lender may reasonably request including the following: 
     (a) the name of the insurer; (b) the risks insured; (c) the amount of 
     the policy; (d) the property insured; (e) the current value on the basis 
     of which insurance has been obtained and the manner of determining that 
     value; and (f) the expiration date of the policy. In addition, Grantor 
     shall upon request by Lender (however not more often than annually) have 
     an independent appraiser satisfactory to Lender determine, as applicable,
     the cash value or replacement cost of the Collateral.

GRANTOR'S RIGHT TO POSSESSION. Until default, Grantor may have possession of 
the tangible personal property and beneficial use of all the Collateral and 
may use it in any lawful manner not inconsistent with this Agreement or the 
Related Documents, provided that Grantor's right to possession and beneficial 
use shall not apply to any Collateral where possession of the Collateral by 
Lender is required by law to perfect Lender's security interest in such 
Collateral. If Lender at any time has possession of any Collateral, whether 
before or after an Event of Default, Lender shall be deemed to have 
exercised reasonable care in the custody and preservation of the Collateral 
if Lender takes such action for the purpose as Grantor shall request or as 
Lender, in Lender's sole discretion, shall deem appropriate under the 
circumstances, but failure to honor any request by Grantor shall not of 
itself be deemed to be a failure to exercise reasonable care. Lender shall not 
be required to take any steps necessary to preserve any rights in the 
Collateral against prior parties, nor to protect, preserve or maintain any 
security interest given to secure the Indebtedness.

EXPENDITURES BY LENDER. If not discharged or paid when due, Lender may (but 
shall not be obligated to) discharge or pay any amounts required to be 
discharged or paid by Grantor under this Agreement, including without 
limitation all taxes, liens, security interests, encumbrances, and other 
claims, at any time levied or placed on the Collateral. Lender also may (but 
shall not be obligated to) pay all costs for insuring, maintaining and 
preserving the Collateral. All such expenditures incurred or paid by Lender 
for such purposes will then bear interest at the rate charged under the 
Indebtedness from the date incurred or paid by Lender to the date of 
repayment by Grantor. All such expenses shall become a part of the 
Indebtedness and at Lender's option, will (a) be payable on demand, (b) be 
added to the balance of the Indebtedness and be apportioned among and be 
payable with any installment payments to become due during either (i) the 
term of any applicable insurance policy or (ii) the remaining term of the 
Indebtedness or (c) be treated as a balloon payment which will be due and 
payable at the Indebtedness' maturity. This Agreement also will secure 
payment of these amounts. Such right shall be in addition to all other rights 
and remedies to which Lender may be entitled upon the occurrence of an Event 
of Default.

RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under this 
Agreement, at any time thereafter, Lender shall have all the rights of a 
secured party under the Washington Uniform Commercial Code. In addition and 
without limitation, Lender may exercise any one or more of the following 
rights and remedies:

     ACCELERATE INDEBTEDNESS. Lender may declare the entire Indebtedness, 
     including any prepayment penalty which Grantor would be required to pay, 
     immediately due and payable.

     ASSEMBLE COLLATERAL. Lender may require Grantor to deliver to Lender all 
     or any portion of the Collateral and any and all certificates of title and 
     other documents relating to the Collateral. Lender may require Grantor to 
     assemble the Collateral and make it available to Lender at a place to be 
     designated by Lender. Lender also shall have full power to enter upon 
     the property of Grantor to take possession of and remove the Collateral. 
     If the Collateral contains other goods not covered by this Agreement at
     the time of repossession, Grantor agrees Lender may take such other goods,
     provided that Lender makes reasonable efforts to return them to Grantor
     after repossession.

     SELL THE COLLATERAL. Lender shall have full power to sell, lease, 
     transfer, or otherwise deal with the Collateral or proceeds thereof in 
     its own name or that of Grantor. Lender may sell the Collateral at 
     public auction or private sale. Unless the Collateral threatens to decline 
     speedily in value or is of a type customarily sold on a recognized 
     market, Lender will give Grantor reasonable notice of the time after 
     which any private sale or any other intended disposition of the 
     Collateral is to be made. The requirements of reasonable notice shall be 
     met if such notice is given at least ten (10) days before the time of 
     the sale or disposition. All expenses relating to the disposition of the

                             COMMERCIAL SECURITY AGREEMENT
                                     (CONTINUED)

     expenses of retaking, holding, insuring, preparing for sale and selling
     the Collateral, shall become a part of the Indebtedness secured by this
     Agreement and shall be payable on demand, with interest at the Note rate 
     from date of expenditure until repaid.

     APPOINT RECEIVER. To the extent permitted by applicable law, Lender 
     shall have the following rights and remedies regarding the appointment of 
     a receiver: (a) Lender may have a receiver appointed as a matter of 
     right, (b) the receiver may be an employee of Lender and may serve 
     without bond, and (c) all fees of the receiver and his or her attorney 
     shall become part of the Indebtedness secured by this Agreement and shall 
     be payable on demand, with interest at the Note rate from date of 
     expenditure until repaid.

     COLLECT REVENUES, APPLY ACCOUNTS. Lender, either itself or through a 
     receiver, may collect the payments, rents, income, and revenues from the 
     Collateral. Lender may at any time in its discretion transfer any 
     Collateral into its own name or that of its nominee and receive the 
     payments, rents, income, and revenue therefrom and hold the same as 
     security for the Indebtedness or apply it to payment of the Indebtedness 
     in such order of preference as Lender may determine. Insofar as the 
     Collateral consists of accounts, general intangibles, insurance 
     policies, instruments, chattel paper, choses in action, or similar 
     property, Lender may demand, collect, receipt for, settle, compromise, 
     adjust, sue for, foreclose, or realize on the Collateral as Lender may 
     determine, whether or not Indebtedness or Collateral is then due. For 
     these purposes, Lender may, on behalf of and in the name of Grantor, 
     receive, open and dispose of mail addressed to Grantor; change any 
     address to which mail and payments are to be sent; and endorse notes, 
     checks, drafts, money orders, documents of title, instruments and items 
     pertaining to payment, shipment, or storage of any Collateral. To 
     facilitate collection, Lender may notify account debtors and obligors on 
     any Collateral to make payments directly to Lender.

     OBTAIN DEFICIENCY. If Lender chooses to sell any or all of the 
     Collateral, Lender may obtain a judgment against Grantor for any 
     deficiency remaining on the Indebtedness due to Lender after 
     application of all amounts received from the exercise of the rights 
     provided in this Agreement. Grantor shall be liable for a deficiency even 
     if the transaction described in this subsection is a sale of accounts or 
     chattel paper.

     OTHER RIGHTS AND REMEDIES. Lender shall have all the rights and remedies 
     of a secured creditor under the provisions of the Uniform Commercial 
     Code, as may be amended from time to time. In addition, Lender shall 
     have and may exercise any or all other rights and remedies it may have 
     available at law, in equity or otherwise.

     CUMULATIVE REMEDIES. All of Lender's rights and remedies, whether 
     evidenced by this Agreement or the Related Documents or by any other 
     writing, shall be cumulative and may be exercised singularly or 
     concurrently. Election by Lender to pursue any remedy shall not exclude 
     pursuit of any other remedy, and an election to make expenditures or to 
     take action to perform an obligation of Grantor under this Agreement, 
     after Grantor's failure to perform, shall not affect Lender's right to 
     declare a default and to exercise its remedies. 

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of 
this Agreement.

     AMENDMENTS. This Agreement, together with any Related Documents, 
     constitutes the entire understanding and agreement of the parties as to 
     the matters set forth in the is Agreement. No alteration of or amendment

     by the party or parties sought to be charged or bound by the alteration or 
     amendment.

     APPLICABLE LAW. This Agreement has been delivered to Lender and accepted 
     by Lender in the State of Washington. If there is a lawsuit, Grantor

     be governed by and construed in accordance with the laws of the State of 
     Washington.

     ATTORNEY'S FEES; EXPENSES. Grantor agrees to pay upon demand all of 
     Lender's costs and expense, including reasonable attorneys' fees and 
     Lender's legal expenses, incurred in connection with the enforcement of 
     this Agreement. Lender may pay someone else to help enforce this 
     Agreement, and Grantor shall pay the costs and expense of such 
     enforcement. Costs and expense include Lender's attorneys' fees and 
     legal expense whether or not there is a lawsuit, including attorneys' 
     fees and legal expenses for bankruptcy proceedings (and including efforts 
     to modify or vacate any automatic stay or injunction), appeals, and any 
     anticipated post-judgment collection services. Grantor also shall pay all 
     court costs and such additional fees as may be directed by the court.

     CAPTION HEADINGS. Caption headings in this Agreement are for convenience 
     purposes only and are not to be used to interpret or define the 
     provisions of this Agreement.

     MULTIPLE PARTIES; CORPORATE AUTHORITY. All obligations of Grantor under 
     this Agreement shall be joint and several, and all references to Grantor

     given at the address shown above. Any party may change it address for 
     notices under this Agreement by giving formal written notice to the 
     other parties, specifying that the purpose of the notice is to change 
     the party's address. To the extent permitted by applicable law, if there 
     is more than one Grantor, notice to any Grantor will constitute notice 
     to all Grantors. For notice purposes, Grantor will keep Lender informed 
     at all times of Grantor's current address(es). Grantor will give Lender 
     prior written notice of any change of either Grantor's legal structure or
     of any change of Grantor's chief executive office, or if Grantor has no 
     place of business, Grantor's residence, and change of records location.

     attorney-in-fact, irrevocably, with full power of substitution to do the 
     following: (a) to demand, collect, receive, receipt for, sue and recover 
     all sums of money or other property which may now or hereafter become 
     due, owing or payable from the Collateral; (b) to execute, sign and 
     endorse any and all claims, instruments, receipts, checks, drafts or 
     warrants issued in payment for the Collateral; (c) to settle or 
     compromise any and all claims arising under the Collateral, and, in the 
     place and stead of Grantor, to execute and deliver its release and 
     settlement for the claim; and (d) to file any claim or claims or to take 
     any action or institute or take part in any proceedings, either in its 
     own name or in the name of Grantor, or otherwise, which in the 
     discretion of Lender may seem to be necessary or advisable. This power 
     is given as security for the Indebtedness, and the authority hereby 
     conferred is and shall be irrevocable and shall remain in full force and 
     effect until renounced by Lender.

     PREFERENCE PAYMENTS. Any monies Lender pays because of an asserted 
     preference claim in Borrower's bankruptcy will become a part of the 
     Indebtedness and, at Lender's option, shall be payable by Borrower as 
     provided above in the "EXPENDITURES BY LENDER" paragraph.

     SEVERABILITY. If a court of competent jurisdication finds any provision of
     this Agreement to be invalid or unenforceable as to any person or 
     circumstance, such finding shall not render that provision invalid or 
     unenforceable as to any other persons or circumstances. If feasible, any 
     such offending provision shall be deemed to be modified to be within the 
     limits of enforceability or validity; however, if the offending

     provisions of this Agreement in all other repsecces shall remain valid 
     and enforceable.

     inure to the benefit of the parties, their successors and assigns.

     WAIVER. Lender shall not be deemed to have waived any rights under this 
     Agreement unless such waiver is given in writing and signed by Lender. No 
     delay or omission on the part of Lender in exercising any right shall  
     operate as a waiver of such right or any other right. A waiver by 
     Lender of a provision of this Agreement shall not prejudice or 
     constitute a waiver of Lender's right otherwise to demand strict 
     compliance with

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

     that provision or any other provision of this Agreement. No prior waiver 
     by Lender, nor any course of dealing between Lender and Grantor, shall 
     constitute a waiver of any of Lender's rights or of any Grantor's 
     obligations as to any future transactions. Whenever the consent of Lender 
     is required under this Agreement, the granting of such consent by Lender 
     in any instance shall not constitute continuing consent of subsequent 
     instances where such consent is required and all cases such consent may 
     be granted or withheld in the sole discretion of Lender.

     WAIVER OF CO-OBLIGOR'S RIGHTS. If more than one person is obligated for 
     the Indebtedness, Borrower irrevocably waivers, disclaims and 
     relinquishes all claims against such other person which Borrower has 
     or would otherwise have by virtue of payment of the Indebtedness or 
     any part thereof, specifically including but not limited to all rights 
     of indemnity, contribution or exoneration.

ADDITIONAL PROVISION. "LENDER" means (a) as to the granting clause of this 
Agreement, Bank of America National Trust and Savings Association, doing 
business as Seafirst Bank ("Seafirst"), as agent for itself and Mellon Bank, 
N.A. ""Mellon"), and means (b) as to all other provisions of this Agreement 
both Bank of America National Trust and Savings Association, doing business 
as Seafirst Bank, and Mellon Bank, N.A., and their respective successors and 
assigns. "INDEBTEDNESS" shall mean all the "Obligations", as such term is 
defined in the Credit Agreement dated as of June 3, 1997 (including all 
amendments thereto and restatements thereof, the "Credit Agreement"), between 
Borrower and Lender, including all renewals, modifications, and extensions 
thereof and all obligations of Grantor under this Agreement. Grantor 
acknowledges and agrees that all rights, powers, and privileges for either 
Seafirst or Mellon, in their respective individual capacities as Banks, 
may be exercised by Seafirst in its capacity as agent for the Banks; and the 
Grantor is neither permitted nor required to inquire as to Seafirst's 
authority to act for the Banks when its it purporting to act in its capacity 
as Agent. This provision does not hinder in any way each Bank's right to 
demand performance in its individual capacity. "COLLATERAL" shall have the 
meaning given to such term in the Credit Agreement. "EVENTS OF DEFAULT" shall 
mean each of the events which constitutes a "Default" under the terms of the
