records of the Company prior to the date of this Agreement and in any Schedule 2
                                                                      ----------
attached to this Agreement as amended from time to time.  No interest shall be
paid on Capital Contributions and no Member shall have the right to withdraw
his, her or its Capital Contribution.

          Additional Capital Contributions shall be required of Class A Members
only upon a written call for additional capital by the Managers setting forth
the aggregate amount of additional capital, the number of additional Class A
Units to be issued in connection with the call for additional capital, and the
subscription price for each Class A Unit.  If the Managers issue a call for
additional Capital Contributions, the Class A Members shall make such additional
Capital Contributions on a pro rata basis in proportion to their respective
ownership of the total Class A Units, such that 100% of the additional Capital
Contribution is funded by the Class A Members, within ten business days after
receipt of notice of the required additional Capital Contribution.  Class B
Members shall have no right or obligation to make additional Capital
Contributions.

          In the event that any Class A Member fails to make a required
additional Capital Contribution within the time required, the non-defaulting
Class A Members may, at their option and as determined by the Managers:

          (a)  recharacterize the additional Capital Contribution made by each
of the non-defaulting Class A Members as a loan to the Company, bearing interest
at a rate equal to the lesser of the maximum rate permitted by law or the SFNB
Prime Rate in effect as of the first day of each calendar month, plus three
percent per annum, with such interest rate being adjusted as of the first day of
each calendar month and with interest payable monthly and principal payable
within thirty (30) days after written demand; or

                                       5

 
          (b) contribute to the Company, pro rata in accordance with the number
of Class A Units held by each non-defaulting Class A Member or in such other
manner as the non-defaulting Class A Members may agree, an amount equal to the
defaulting Member's required additional Capital Contribution in exchange for
additional Class A Units at the subscription price set forth in the Managers'
call for additional capital; or

          (c) advance, pro rata in accordance with the number of Class A Units
held by each non-defaulting Class A Member or in such other manner as the non-
defaulting Class A Members may agree, an amount equal to such required
additional Capital Contribution on behalf of the defaulting Member (a "Default
Loan").  Default Loans shall bear interest at the lesser of the maximum rate
permitted by law or the SFNB Prime Rate in effect as of the first day of each
calendar month, plus 3% per annum, and such interest rate shall be adjusted as
of the first day of each calendar month.  Default Loans shall be repayable
within thirty (30) days after written demand and if not sooner repaid or demand
made, shall be repaid from any cash distributions otherwise distributable by the
Company to the defaulting Member (and charged against the Defaulting Member's
Capital Account) or offset against any amount to be paid to the defaulting
Member by the Company.

          Following the contribution of additional capital and the issuance of
additional Class A Units pursuant to the call of the Managers under this Section
                                                                         -------
3.2, the Percentage Interests of the Members shall be adjusted so that the
- ---                                                                       
Percentage Interest of each Member is in the ratio of a fraction, the numerator
of which is the aggregate number of Units held by each Member and the
denominator of which is the aggregate number of Units held by all Members, and
Schedule 1 shall be amended accordingly.
- ----------                              

          3.3  ADDITIONAL MEMBERS; EQUITY OPTION PLAN.  The Company may, as
determined by the Managers time to time, admit additional persons as Members, or
grant options to persons to become Members, pursuant to the Equity Option Plan
or otherwise.  The Equity Option Plan, and additional agreements executed
pursuant to the terms of the Equity Option Plan, shall govern the terms of any
options to become a Member.  Persons admitted as Members pursuant to the Equity
Option Plan shall be admitted as Class B Members.

          3.4  CAPITAL ACCOUNTS.  A capital account ("Capital Account") shall be
determined and maintained for each Member in accordance with the principles of
Regulation Section 1.704-1(b) at all times throughout the full term of the
Company.  In the event of a permitted sale or assignment of all or any part of a
Member's interest in the Company, the Capital Account of the transferor shall
become the Capital Account of the transferee to the extent it relates to the
transferred Company interest.

                                       6

 
          The book value of all Company properties may be adjusted to equal
their respective gross fair market values, as determined by the Managers, as of
the following times:  (1) in connection with the acquisition of an interest in
the Company by a new or existing Member, (2) in connection with the liquidation
of the Company as defined in Regulation Section 1.704-(1)(b)(2)(ii)(g), or (3)
in connection with a distribution to a retiring or a continuing Member as
consideration for all or a portion of his, her or its interest in the Company.
In the event of a revaluation of any Company assets hereunder, the Capital
Accounts of the Members shall be adjusted, including continuing adjustments for
depreciation, to the extent provided in Regulation Section 1.704-
(1)(b)(2)(iv)(f).

          3.5  NO WITHDRAWAL OR TRANSFER OF MEMBER'S INTEREST.  No Member shall
voluntarily withdraw from the Company without the consent of the Managers.  A
withdrawal in violation of this Section 3.5 shall constitute a breach of this
                                -----------                                  
Agreement for which the Company and other Members shall have the remedies
provided under applicable law.

          No Member shall voluntarily assign, encumber, sell or otherwise
transfer all or any portion of the Member's interest in the Company or options
to acquire any interest in the Company (except as set forth in the Equity Option
Plan governing such option), or enter into any agreement as a result of which
any person shall become interested with the Member in the Company, without the
consent of a Majority Percentage Interest of the non-transferring Members.  The
Members acknowledge and agree that this is a reasonable restraint on the
alienation of their interests in the Company in view of the paramount objective
of the Members that the Company be treated as a partnership for federal income
tax purposes.

                        ARTICLE 4 -- MEETINGS OF MEMBERS

          4.1  MEETINGS.  Meetings of Members are not required, but may be
called by Class A Members holding at least twenty percent (20%) of the
Percentage Interests held by Members; provided, however, that Class A Members
holding at least fifteen percent (15%) of the Percentage Interests held by
Members may call a meeting of Members once per year.  No business shall be
transacted at any meeting of Members except as is specified in the notice
calling such meeting.

          4.2  PLACE OF MEETINGS.  The Members may designate any place, either
within or outside the State of Washington, as the place of meeting for any
meeting of the Members.  If no designation is made, the place of meeting shall

times and under circumstances determined by the Managers in the following order
of priority:

          (a) first, the Company shall make a distribution to the Members in an
amount equal to at least (a) the Company's net taxable income during the fiscal

year that are required to be made under the provisions of this Section 8.1(a)

with respect to a prior fiscal year).  Such distribution shall be made to each
Member in proportion to the net taxable income reported on such Member's Form K-

          for an S Corporation.  The calculation of SRC's net taxable income for
          this purpose shall not include any consideration received by SRC under
          the Member Contribution and Asset Purchase Agreement between the
          Company and SRC.

          1995.

          tax rates imposed on individuals during 1995).

     D =  The aggregate amount of distributions made by SRC to its shareholders
          during the period commencing on January 1, 1995 and ending on August

     12.12 DISPUTE RESOLUTION.

          12.12.1 DISPUTE RESOLUTION.  The parties to this Agreement desire to
resolve disputes arising out of this Agreement without litigation.  Accordingly,
except for action seeking a temporary restraining order injunction related to
the purposes of this Agreement, or suit to compel compliance with this dispute
resolution process, the parties agree to use the dispute resolution procedures
set forth in Section 12.12 as their sole remedy with respect to any controversy
             -------------                                                     
or claim arising out of or relating to this Agreement or its breach.

     At the written request of any party, the parties to the dispute will
appoint knowledgeable, responsible representatives to meet and negotiate in good
faith to resolve any dispute arising under this Agreement.  The parties intend
that these negotiations be conducted by non-lawyer, business representatives.
The location, format, frequency, duration and conclusion of these discussions
shall be left to the discretion of the representatives.  Discussion and
correspondence among the representatives for purposes of these negotiations
shall be treated as confidential information developed for purposes of
settlement, exempt from discovery and production, which shall not be admissible
in the arbitration described below.  Documents identified in or provided with
such communications, which are not prepared for purposes of the negotiations,
are not so exempted and may, if otherwise admissible, be admitted in evidence in
the arbitration or lawsuit.

          12.12.2 MEDIATION.  If the negotiations set forth in Section 12.12.1
                                                               ---------------
do not resolve the dispute within sixty (60) days of the initial written
request, the parties agree to work in good faith to settle the dispute by
mediation under the commercial mediation rules of the American Arbitration
Association.  The parties will attempt to agree on a mediator.  If they are
unable to do so, the mediation will be referred to the Seattle office of the
American Arbitration Association for mediation which will appoint a qualified
mediator to serve.  The mediation shall take place in Seattle.  Unless the
parties agree otherwise, the first mediation session shall take place no later
than ninety (90) days after the initial written request to negotiate. The
mediation shall continue until the dispute is resolved or until such time

                                       22

 
as the mediator makes a good faith determination that the likelihood of
resolution is sufficiently remote that continuation of the mediation is not
warranted.

          12.12.3 ARBITRATION.  If a determination is made pursuant to Section
                                                                       -------
12.12.2 that continuation of the mediation process is not warranted, the dispute
- -------                                                                         
shall be submitted to binding arbitration by a panel of three arbitrators
pursuant to the Commercial Arbitration Rules of the American Arbitration
Association.  Any party may demand such arbitration in accordance with the
procedures set out in those rules.  Each party shall have the right to take the
deposition of one individual, and any expert witness designated by the other
party.  Each party shall also have the right to request production of relevant
documents, the scope and enforcement of which shall be governed by the
arbitrator.  Additional discovery may be only by order of the arbitrator, and
only upon a showing of substantial need.  The arbitrator shall be authorized to
issue subpoenas for the purpose of requiring attendance of witnesses at
depositions.  The arbitration hearing shall be commenced within sixty (60) days
of the determination that mediation is not going to be successful.  The
arbitration shall be held in Seattle, Washington or such other location as
mutually agreed upon by the parties.  The arbitrator shall control the
scheduling so as to process the matter expeditiously.  The parties may submit
written briefs.  The arbitrator shall rule on the dispute by issuing a written
opinion within thirty (30) days after the close of hearings.  The times
specified in this section may be extended upon mutual agreement of the parties
or by the arbitrator upon a showing of good cause.  The award rendered by
arbitration shall be final, binding and nonappealable judgment and the award may
be entered in any court of competent jurisdiction in the United States.
Punitive damages shall not be awarded by the arbitrator.

          12.12.4 CONFIDENTIALITY.  The parties agree that all communications
and negotiations between the parties during the dispute resolution process, any
settlements agreed upon during the dispute resolution process and any
information regarding the other party obtained during the dispute resolution
process (that are not already public knowledge) are confidential and may be
disclosed only to employees and agents of the parties who shall have a "need to
know" the information and who shall have been made aware of the confidentiality
obligations set forth in this Section, unless the party is required by law to
disclose such information.

          12.12.5 FEES AND EXPENSES.  The parties shall equally split the fees
of the mediator and the arbitrator.  Any party found by the arbitrator to have
breached this Agreement shall pay all other costs and expenses, including
reasonable attorneys' fees and expenses, of the other party incurred in
connection with the dispute resolution process. If the arbitrator does not find

                                       23

 
that any party has breached this Agreement, then each party shall bear its own
costs and expenses, including attorneys' fees and expenses.

     12.13 COUNTERPARTS.  This Agreement may be executed in counterparts, each
of which shall be deemed an original but all of which shall constitute one and
the same instrument.
