ASYMETRIX LEARNING SYSTEMS, INC.

                             1998 EQUITY INCENTIVE PLAN

             As Adopted by the Board of Directors on December 29, 1997
                    And as Amended on May 25, 1999

       1.     PURPOSE.  The purpose of this Plan is to provide incentives to
attract, retain and motivate eligible persons whose present and potential
contributions are important to the success of the Company, and any of its
Parent and Subsidiaries, by offering them an opportunity to participate in
the Company's future performance through awards of Options, Restricted Stock
and Stock Bonuses.  Capitalized terms not defined in the text are defined in
Section 23.

       2.     SHARES SUBJECT TO THE PLAN.

              2.1    NUMBER OF SHARES AVAILABLE.  Subject to Sections 2.2 and
18, the total number of Shares reserved and available for grant and issuance
pursuant to this Plan will be 2,500,000 Shares.  Subject to Sections 2.2 and
18, Shares that: (a) are subject to issuance upon exercise of an Option but
cease to be subject to such Option for any reason other than exercise of such
Option; (b) are subject to an Award granted hereunder but are forfeited or
are repurchased by the Company at the original issue price; or (c) are
subject to an Award that otherwise terminates without Shares being issued,
will again be available for grant and issuance in connection with future
Awards under this Plan.  Any authorized shares not issued or subject to
outstanding grants under the Company's 1995 Combined Incentive and
Nonqualified Stock Option Plan (the "Prior Plan") on the Effective Date (as
defined below) and any shares that are issuable upon exercise of options
granted pursuant to the Prior Plan that expire or become unexercisable for
any reason without having been exercised in full, will no longer be available
for grant and issuance under the Prior Plan, but will be available for grant
and issuance under this Plan.  In addition, any shares issued under the Prior
Plan which are repurchased or forfeited will be available for grant and
issuance under this Plan.  At all times the Company shall reserve and keep
available a sufficient number of Shares as shall be required to satisfy the
requirements of all outstanding Options granted under this Plan and all other
outstanding but unvested Awards granted under this Plan.

              2.2    ADJUSTMENT OF SHARES.  In the event that the number of
outstanding shares is changed by a stock dividend, recapitalization, stock
split, reverse stock split, subdivision, combination, reclassification or
similar change in the capital structure of the Company without consideration,
then (a) the number of Shares reserved for issuance under this Plan, (b) the
Exercise Prices of and number of Shares subject to outstanding Options, and
(c) the number of Shares subject to other outstanding Awards will be
proportionately adjusted, subject to any required action by the Board or the
stockholders of the Company and compliance with applicable securities laws;
PROVIDED, HOWEVER, that fractions of a Share will not be issued but will
either be replaced by a cash payment equal to the Fair Market Value of such
fraction of a Share or will be rounded up to the nearest whole Share, as
determined by the Committee.

       3.     ELIGIBILITY.  ISOs (as defined in Section 5 below) may be
granted only to employees (including officers and directors who are also
employees) of the Company or of a Parent or Subsidiary of the Company.  All
other Awards may be granted to employees, officers, directors, consultants,
independent contractors and advisors of the Company or any Parent or
Subsidiary of the Company; PROVIDED such consultants, contractors and
advisors render bona fide services not in connection with the offer and sale
of securities in a capital-raising transaction.  No person will be eligible
to receive more than 500,000 Shares in any calendar year under this Plan
pursuant to the grant of Awards hereunder, other than new employees of the
Company or of a Parent or Subsidiary of the Company (including new employees
who are also officers and directors of the Company or any Parent or
Subsidiary of the Company), who are eligible to receive up to a maximum of
1,000,000 Shares in the calendar year in which they commence their
employment.  A person may be granted more than one Award under this Plan.

       4.     ADMINISTRATION.


              4.1    COMMITTEE AUTHORITY.  This Plan will be administered by
the Committee or by the Board acting as the Committee.  Subject to the
general purposes, terms and conditions of this Plan, and to the direction of
the Board, the Committee will have full power to implement and carry out this
Plan.  Without limitation, the Committee will have the authority to:

       (a)    construe and interpret this Plan, any Award Agreement and any
              other agreement or document executed pursuant to this Plan;

       (b)    prescribe, amend and rescind rules and regulations relating to
              this Plan or any Award;

       (c)    select persons to receive Awards;

       (d)    determine the form and terms of Awards;

       (e)    determine the number of Shares or other consideration subject to
              Awards; PROVIDED, HOWEVER, that any single Award of more than
              20,000 shares to any individual shall require the approval of the
              entire Board;

       (f)    determine whether Awards will be granted singly, in combination
              with, in tandem with, in replacement of, or as alternatives to,
              other Awards under this Plan or any other incentive or
              compensation plan of the Company or any Parent or Subsidiary of
              the Company;

       (g)    grant waivers of Plan or Award conditions;

       (h)    determine the vesting, exercisability and payment of Awards;

       (i)    correct any defect, supply any omission or reconcile any
              inconsistency in this Plan, any Award or any Award Agreement;

       (j)    determine whether an Award has been earned; and

       (k)    make all other determinations necessary or advisable for the
              administration of this Plan.

              4.2    COMMITTEE DISCRETION.  Any determination made by the
Committee with respect to any Award will be made in its sole discretion at
the time of grant of the Award or, unless in contravention of any express
term of this Plan or Award, at any later time, and such determination will be
final and binding on the Company and on all persons having an interest in any
Award under this Plan.  The Committee may delegate to one or more officers of
the Company the authority to grant an Award under this Plan to Participants
who are not Insiders of the Company.

       5.     OPTIONS.  The Committee may grant Options to eligible persons
and will determine whether such Options will be Incentive Stock Options
within the meaning of the Code ("ISOs") or Nonqualified Stock Options
("NQSOs"), the number of Shares subject to the Option, the Exercise Price of
the Option, the period during which the Option may be exercised, and all
other terms and conditions of the Option, subject to the following:

              5.1    FORM OF OPTION GRANT.  Each Option granted under this
Plan will be evidenced by an Award Agreement which will expressly identify
the Option as an ISO or an NQSO ("STOCK OPTION AGREEMENT"), and will be in
such form and contain such provisions (which need not be the same for each
Participant) as the Committee may from time to time approve, and which will
comply with and be subject to the terms and conditions of this Plan.


                                     - 2 -





              5.2    DATE OF GRANT.  The date of grant of an Option will be
the date on which the Committee makes the determination to grant such Option,
unless otherwise specified by the Committee.  The Stock Option Agreement and
a copy of this Plan will be delivered to the Participant within a reasonable
time after the granting of the Option.

              5.3    EXERCISE PERIOD AND EXERCISABILITY.  Options may be
exercisable within the times or upon the events determined by the Committee
as set forth in the Stock Option Agreement governing such Option; PROVIDED,
HOWEVER, that no Option will be exercisable after the expiration of ten (10)
years from the date the Option is granted; and PROVIDED FURTHER that no ISO
granted to a person who directly or by attribution owns more than ten percent
(10%) of the total combined voting power of all classes of stock of the
Company or of any Parent or Subsidiary of the Company ("TEN PERCENT
STOCKHOLDER") will be exercisable after the expiration of five (5) years from
the date the ISO is granted.  The Committee also may provide for Options to
become exercisable at one time or from time to time, periodically or
otherwise, in such number of Shares or percentage of Shares as the Committee
determines.  Unless otherwise determined by the Committee, the Award
Agreement for any Option granted to a full time employee that becomes
exercisable over time shall provide that if, subsequent to the grant date of
an Option, such employee's work schedule is reduced such that the employee is
working less than full time but has not been Terminated, then the number of
Shares or percentage of Shares that become exercisable at the times specified
in the Award Agreement shall be reduced in proportion to the reduction in the
employee's work schedule.

              5.4    EXERCISE PRICE.  The Exercise Price of an Option will be
determined by the Committee when the Option is granted and may be not less
than 85% of the Fair Market Value of the Shares on the date of grant;
provided that: (i) the Exercise Price of an ISO will be not less than 100% of
the Fair Market Value of the Shares on the date of grant; and (ii) the
Exercise Price of any ISO granted to a Ten Percent Stockholder will not be
less than 110% of the Fair Market Value of the Shares on the date of grant.
Payment for the Shares purchased may be made in accordance with Section 8 of
this Plan.

              5.5    METHOD OF EXERCISE.  Options may be exercised only by
delivery to the Company of a written stock option exercise agreement  (the
"EXERCISE AGREEMENT") in a form approved by the Committee (which need not be
the same for each Participant), stating the number of Shares being purchased,
the restrictions imposed on the Shares purchased under such Exercise
Agreement, if any, and such representations and agreements regarding
Participant's investment intent and access to information and other matters,
if any, as may be required or desirable by the Company to comply with
applicable securities laws, together with payment in full of the Exercise
Price for the number of Shares being purchased.

              5.6    TERMINATION.  Notwithstanding the exercise periods set
forth in the Stock Option Agreement, exercise of an Option will always be
subject to the following:

       (a)    If the Participant is Terminated for any reason except death or
              Disability, then the Participant may exercise such Participant's
              Options only to the extent that such Options would have been
              exercisable upon the Termination Date no later than three (3)
              months after the Termination Date (or such shorter or longer time
              period not exceeding five (5) years as may be determined by the
              Committee, with any exercise beyond three (3) months after the
              Termination Date deemed to be an NQSO), but in any event, no later
              than the expiration date of the Options.

       (b)    If the Participant is Terminated because of Participant's death or
              Disability (or the Participant dies within three (3) months after
              a Termination other than because of Participant's death or
              disability), then Participant's Options may be exercised only to
              the extent that such Options would have been exercisable by
              Participant on the Termination Date and must be exercised by
              Participant (or Participant's legal representative or authorized
              assignee) no later than twelve (12) months after the Termination
              Date (or such shorter or longer time period not exceeding five (5)
              years as may be determined by the Committee, with any such


                                     - 3 -




              exercise beyond (a) three (3) months after the Termination Date
              when the Termination is for any reason other than the
              Participant's death or Disability, or (b) twelve (12) months after
              the Termination Date when the Termination is for Participant's
              death or Disability, deemed to be an NQSO), but in any event no
              later than the expiration date of the Options.

       (c)    Notwithstanding the provisions in paragraph 5.6(a) above, if a
              Participant is terminated for Cause, neither the Participant, the
              Participant's estate nor such other person who may then hold the
              Option shall be entitled to exercise any Option with respect to
              any Shares whatsoever, after termination of service, whether or
              not after termination of service the Participant may receive
              payment from the Company or Subsidiary for vacation pay, for
              services rendered prior to termination, for services rendered for
              the day on which termination occurs, for salary in lieu of notice,
              or for any other benefits.  In making such determination, the
              Board shall give the Participant an opportunity to present to the
              Board evidence on his or her behalf.  For the purpose of this
              paragraph, termination of service shall be deemed to occur on the
              date when the Company dispatches notice or advice to the
              Participant that his or her service is terminated.

              5.7    LIMITATIONS ON EXERCISE.  The Committee may specify a
reasonable minimum number of Shares that may be purchased on any exercise of an
Option, provided that such minimum number will not prevent Participant from
exercising the Option for the full number of Shares for which it is then
exercisable.

              5.8    LIMITATIONS ON ISOs.  The aggregate Fair Market Value
(determined as of the date of grant) of Shares with respect to which ISOs are
exercisable for the first time by a Participant during any calendar year (under
this Plan or under any other incentive stock option plan of the Company, Parent
or Subsidiary of the Company) will not exceed $100,000.  If the Fair Market
Value of Shares on the date of grant with respect to which ISOs are exercisable
for the first time by a Participant during any calendar year exceeds $100,000,
then the Options for the first $100,000 worth of Shares to become exercisable in
such calendar year will be ISOs and the Options for the amount in excess of
$100,000 that become exercisable in that calendar year will be NQSOs.  In the
event that the Code or the regulations promulgated thereunder are amended after
the Effective Date of this Plan to provide for a different limit on the Fair
Market Value of Shares permitted to be subject to ISOs, such different limit
will be automatically incorporated herein and will apply to any Options granted
after the effective date of such amendment.

              5.9    MODIFICATION, EXTENSION OR RENEWAL.  The Committee may
modify, extend or renew outstanding Options and authorize the grant of new
Options in substitution therefor, provided that any such action may not, without
the written consent of a Participant, impair any of such Participant's rights
under any Option previously granted.  Any outstanding ISO that is modified,
extended, renewed or otherwise altered will be treated in accordance with
Section 424(h) of the Code.  The Committee may reduce the Exercise Price of
outstanding Options without the consent of Participants affected by a written
notice to them; PROVIDED, HOWEVER, that the Exercise Price may not be reduced
below the minimum Exercise Price that would be permitted under Section 5.4 of
this Plan for Options granted on the date the action is taken to reduce the
Exercise Price.

              5.10   NO DISQUALIFICATION.  Notwithstanding any other provision
in this Plan, no term of this Plan relating to an ISO will be interpreted,
amended or altered, nor will any discretion or authority granted under this Plan
be exercised, so as to disqualify this Plan under Section 422 of the Code or,
without the consent of the Participant affected, to disqualify any ISO under
Section 422 of the Code.

       6.     RESTRICTED STOCK.  A Restricted Stock Award is an offer by the
Company to sell to an eligible person Shares that are subject to restrictions.
The Committee will determine to whom an offer will be made, the number of Shares
the person may purchase, the price to be paid (the "PURCHASE PRICE"), the
restrictions to which the Shares will be subject, and all other terms and
conditions of the Restricted Stock Award, subject to the following:


                                     - 4 -




              6.1    FORM OF RESTRICTED STOCK AWARD.  All purchases under a
Restricted Stock Award made pursuant to this Plan will be evidenced by an Award
Agreement ("RESTRICTED STOCK PURCHASE AGREEMENT") that will be in such form
(which need not be the same for each Participant) as the Committee will from
time to time approve, and will comply with and be subject to the terms and
conditions of this Plan.  The offer of Restricted Stock will be accepted by the
Participant's execution and delivery of the Restricted Stock Purchase Agreement
and full payment for the Shares to the Company within thirty (30) days from the
date the Restricted Stock Purchase Agreement is delivered to the person.  If
such person does not execute and deliver the Restricted Stock Purchase Agreement
along with full payment for the Shares to the Company within thirty (30) days,
then the offer will terminate, unless otherwise determined by the Committee.

              6.2    PURCHASE PRICE.  The Purchase Price of Shares sold pursuant
to a Restricted Stock Award will be determined by the Committee on the date the
Restricted Stock Award is granted, except in the case of a sale to a Ten Percent
Stockholder, in which case the Purchase Price will be 100% of the Fair Market
Value.  Payment of the Purchase Price may be made in accordance with Section 8
of this Plan.

              6.3    TERMS OF RESTRICTED STOCK AWARDS.  Restricted Stock Awards
shall be subject to such restrictions as the Committee may impose.  These
restrictions may be based upon completion of a specified number of years of
service with the Company or upon completion of the performance goals as set out
in advance in the Participant's individual Restricted Stock Purchase Agreement.
Restricted Stock Awards may vary from Participant to Participant and between
groups of Participants.  Prior to the grant of a Restricted Stock Award, the
Committee shall:  (a) determine the nature, length and starting date of any
Performance Period for the Restricted Stock Award; (b) select from among the
Performance Factors to be used to measure performance goals, if any; and (c)
determine the number of Shares that may be awarded to the Participant.  Prior to
the payment of any Restricted Stock Award, the Committee shall determine the
extent to which such Restricted Stock Award has been earned.  Performance
Periods may overlap and Participants may participate simultaneously with respect
to Restricted Stock Awards that are subject to different Performance Periods and
having different performance goals and other criteria.

              6.4    TERMINATION DURING PERFORMANCE PERIOD.  If a Participant is
Terminated during a Performance Period for any reason, then such Participant
will be entitled to payment (whether in Shares, cash or otherwise) with respect
to the Restricted Stock Award only to the extent earned as of the date of
Termination in accordance with the Restricted Stock Purchase Agreement, unless
the Committee will determine otherwise.

       7.     STOCK BONUSES.

              7.1    AWARDS OF STOCK BONUSES.  A Stock Bonus is an award of
Shares (which may consist of Restricted Stock) for services rendered to the
Company or any Parent or Subsidiary of the Company.  A Stock Bonus may be
awarded for past services already rendered to the Company, or any Parent or
Subsidiary of the Company pursuant to an Award Agreement (the "STOCK BONUS
AGREEMENT") that will be in such form (which need not be the same for each
Participant) as the Committee will from time to time approve, and will comply
with and be subject to the terms and conditions of this Plan.  A Stock Bonus
may be awarded upon satisfaction of such performance goals as are set out in
advance in the Participant's individual Award Agreement (the "PERFORMANCE
STOCK BONUS AGREEMENT") that will be in such form (which need not be the same
for each Participant) as the Committee will from time to time approve, and
will comply with and be subject to the terms and conditions of this Plan.
Stock Bonuses may vary from Participant to Participant and between groups of
Participants, and may be based upon the achievement of the Company, Parent or
Subsidiary and/or individual performance factors or upon such other criteria
as the Committee may determine.

              7.2    TERMS OF STOCK BONUSES.  The Committee will determine the
number of Shares to be awarded to the Participant.  If the Stock Bonus is being
earned upon the satisfaction of performance goals pursuant to a Performance
Stock Bonus Agreement, then the Committee will: (a)  determine the nature,
length and starting date of any Performance Period for each Stock Bonus; (b)
select from among the Performance Factors to be used to measure the performance,
if any; and (c) determine the number of Shares that may be awarded to the
Participant.  Prior to the payment of any Stock Bonus, the Committee shall
determine the extent to which such


                                     - 5 -



Stock Bonuses have been earned.  Performance Periods may overlap and
Participants may participate simultaneously with respect to Stock Bonuses
that are subject to different Performance Periods and different performance
goals and other criteria.  The number of Shares may be fixed or may vary in
accordance with such performance goals and criteria as may be determined by
the Committee.  The Committee may adjust the performance goals applicable to
the Stock Bonuses to take into account changes in law and accounting or tax
rules and to make such adjustments as the Committee deems necessary or
appropriate to reflect the impact of extraordinary or unusual items, events
or circumstances to avoid windfalls or hardships.

              7.3    FORM OF PAYMENT.  The earned portion of a Stock Bonus may
be paid currently or on a deferred basis with such interest or dividend
equivalent, if any, as the Committee may determine.  Payment may be made in the
form of cash or whole Shares or a combination thereof, either in a lump sum
payment or in installments, all as the Committee will determine.

       8.     PAYMENT FOR SHARE PURCHASES.

              8.1    PAYMENT.  Payment for Shares purchased pursuant to this
Plan may be made in cash (by check) or, where expressly approved for the
Participant by the Committee and where permitted by law:

       (a)    by cancellation of indebtedness of the Company to the Participant;

       (b)    by surrender of shares that either:  (1) have been owned by
              Participant for more than six (6) months and have been paid for
              within the meaning of SEC Rule 144 (and, if such shares were
              purchased from the Company by use of a promissory note, such note
              has been fully paid with respect to such shares); or (2) were
              obtained by Participant in the public market;

       (c)    by tender of a full recourse promissory note having such terms as
              may be approved by the Committee and bearing interest at a rate
              sufficient to avoid imputation of income under Sections 483 and
              1274 of the Code; PROVIDED, HOWEVER, that Participants who are not
              employees or directors of the Company will not be entitled to
              purchase Shares with a promissory note unless the note is
              adequately secured by collateral other than the Shares;

       (d)    by waiver of compensation due or accrued to the Participant for
              services rendered;

       (e)    with respect only to purchases upon exercise of an Option, and
              provided that a public market for the Company's stock exists:

              (1)    through a "same day sale" commitment from the Participant
                     and a broker-dealer that is a member of the National
                     Association of Securities Dealers (an "NASD DEALER")
                     whereby the Participant irrevocably elects to exercise the
                     Option and to sell a portion of the Shares so purchased to
                     pay for the Exercise Price, and whereby the NASD Dealer
                     irrevocably commits upon receipt of such Shares to forward
                     the Exercise Price directly to the Company; or

              (2)    through a "margin" commitment from the Participant and a
                     NASD Dealer whereby the Participant irrevocably elects to
                     exercise the Option and to pledge the Shares so purchased
                     to the NASD Dealer in a margin account as security for a
                     loan from the NASD Dealer in the amount of the Exercise
                     Price, and whereby the NASD Dealer irrevocably commits upon
                     receipt of such Shares to forward the Exercise Price
                     directly to the Company; or

       (f)    by any combination of the foregoing.


                                     - 6 -




              8.2    LOAN GUARANTEES.  The Committee may help the Participant
pay for Shares purchased under this Plan by authorizing a guarantee by the
Company of a third-party loan to the Participant.

       9.     WITHHOLDING TAXES.

              9.1    WITHHOLDING GENERALLY.  Whenever Shares are to be issued in
satisfaction of Awards granted under this Plan, the Company may require the
Participant to remit to the Company an amount sufficient to satisfy federal,
state and local withholding tax requirements prior to the delivery of any
certificate or certificates for such Shares.  Whenever, under this Plan,
payments in satisfaction of Awards are to be made in cash, such payment will be
net of an amount sufficient to satisfy federal, state, and local withholding tax
requirements.

              9.2    STOCK WITHHOLDING.  When, under applicable tax laws, a
Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may in its
sole discretion allow the Participant to satisfy the minimum withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
that number of Shares having a Fair Market Value equal to the minimum amount
required to be withheld, determined on the date that the amount of tax to be
withheld is to be determined.  All elections by a Participant to have Shares
withheld for this purpose will be made in accordance with the requirements
established by the Committee and be in writing in a form acceptable to the
Committee

       10.    PRIVILEGES OF STOCK OWNERSHIP.

              10.1   VOTING AND DIVIDENDS.  No Participant will have any of the
rights of a stockholder with respect to any Shares until the Shares are issued
to the Participant.  After Shares are issued to the Participant, the Participant
will be a stockholder and have all the rights of a stockholder with respect to
such Shares, including the right to vote and receive all dividends or other
distributions made or paid with respect to such Shares; PROVIDED, that if such
Shares are Restricted Stock, then any new, additional or different securities
the Participant may become entitled to receive with respect to such Shares by
virtue of a stock dividend, stock split or any other change in the corporate or
capital structure of the Company will be subject to the same restrictions as the
Restricted Stock; PROVIDED, FURTHER, that the Participant will have no right to
retain such stock dividends or stock distributions with respect to Shares that
are repurchased at the Participant's Purchase Price or Exercise Price pursuant
to Section 12.

              10.2   FINANCIAL STATEMENTS.  The Company will, upon the request
of a Participant, provide the financial statements included in its most recent
Form 10-K or 10-Q to Participant prior to such Participant's purchase of Shares
under this Plan, and will, upon the request of a Participant, provide such
Participant with the most recent annual report of the Company during the period
such Participant has Awards outstanding; PROVIDED, HOWEVER, the Company will not
be required to provide such financial statements to Participants whose services
in connection with the Company assure them access to equivalent information.

       11.    TRANSFERABILITY.  Awards granted under this Plan, and any interest
therein, will not be transferable or assignable by Participant, and may not be
made subject to execution, attachment or similar process, otherwise than by will
or by the laws of descent and distribution or as determined by the Committee and
set forth in the Award Agreement with respect to Awards that are not ISOs.
During the lifetime of the Participant an Award will be exercisable only by the
Participant, and any elections with respect to an Award may be made only by the
Participant unless otherwise determined by the Committee and set forth in the
Award Agreement with respect to Awards that are not ISOs.

       12.    RESTRICTIONS ON SHARES.  At the discretion of the Committee, the
Company may reserve to itself and/or its assignee(s) in the Award Agreement a
right to repurchase a portion of or all Unvested Shares held by a Participant
following such Participant's Termination at any time within ninety (90) days
after the later of Participant's Termination Date and the date Participant
purchases Shares under this Plan, for cash and/or


                                    - 7 -




cancellation of purchase money indebtedness, at the Participant's Exercise
Price or Purchase Price, as the case may be.

       13.    CERTIFICATES.  All certificates for Shares or other securities
delivered under this Plan will be subject to such stock transfer orders, legends
and other restrictions as the Committee may deem necessary or advisable,
including restrictions under any applicable federal, state or foreign securities
law, or any rules, regulations and other requirements of the SEC or any stock
exchange or automated quotation system upon which the Shares may be listed or
quoted.

       14.    ESCROW; PLEDGE OF SHARES.  To enforce any restrictions on a
Participant's Shares, the Committee may require the Participant to deposit all
certificates representing Shares, together with stock powers or other
instruments of transfer approved by the Committee, appropriately endorsed in
blank, with the Company or an agent designated by the Company to hold in escrow
until such restrictions have lapsed or terminated, and the Committee may cause a
legend or legends referencing such restrictions to be placed on the
certificates.  Any Participant who is permitted to execute a promissory note as
partial or full consideration for the purchase of Shares under this Plan will be
required to pledge and deposit with the Company all or part of the Shares so
purchased as collateral to secure the payment of Participant's obligation to the
Company under the promissory note; PROVIDED, HOWEVER, that the Committee may
require or accept other or additional forms of collateral to secure the payment
of such obligation and, in any event, the Company will have full recourse
against the Participant under the promissory note notwithstanding any pledge of
the Participant's Shares or other collateral.  In connection with any pledge of
the Shares, Participant will be required to execute and deliver a written pledge
agreement in such form as the Committee will from time to time approve.  The
Shares purchased with the promissory note may be released from the pledge on a
pro rata basis as the promissory note is paid.

       15.    EXCHANGE AND BUYOUT OF AWARDS.  The Committee may, at any time or
from time to time, authorize the Company, with the consent of the respective
Participants, to issue new Awards in exchange for the surrender and cancellation
of any or all outstanding Awards.  The Committee may at any time buy from a
Participant an Award previously granted with payment in cash, Shares (including
Restricted Stock) or other consideration, based on such terms and conditions as
the Committee and the Participant may agree.

       16.    SECURITIES LAW AND OTHER REGULATORY COMPLIANCE.  An Award will
not be effective unless such Award is in compliance with all applicable
federal and state securities laws, rules and regulations of any governmental
body, and the requirements of any stock exchange or automated quotation
system upon which the Shares may then be listed or quoted, as they are in
effect on the date of grant of the Award and also on the date of exercise or
other issuance. Notwithstanding any other provision in this Plan, the Company
will have no obligation to issue or deliver certificates for Shares under
this Plan prior to: (a) obtaining any approvals from governmental agencies
that the Company determines are necessary or advisable; and/or (b) completion
of any registration or other qualification of such Shares under any state or
federal law or ruling of any governmental body that the Company determines to
be necessary or advisable.  The Company will be under no obligation to
register the Shares with the SEC or to effect compliance with the
registration, qualification or listing requirements of any state securities
laws, stock exchange or automated quotation system, and the Company will have
no liability for any inability or failure to do so.

       17.    NO OBLIGATION TO EMPLOY.  Nothing in this Plan or any Award
granted under this Plan will confer or be deemed to confer on any Participant
any right to continue in the employ of, or to continue any other relationship
with, the Company or any Parent or Subsidiary of the Company or limit in any way
the right of the Company or any Parent or Subsidiary of the Company to terminate
Participant's employment or other relationship at any time, with or without
cause.

       18.    CORPORATE TRANSACTIONS.

              18.1   ASSUMPTION OR REPLACEMENT OF AWARDS BY SUCCESSOR.  In the
event of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving


                                    - 8 -




corporation (other than a merger or consolidation with a wholly-owned
subsidiary, a reincorporation of the Company in a different jurisdiction, or
other transaction in which there is no substantial change in the stockholders
of the Company or their relative stock holdings and the Awards granted under
this Plan are assumed, converted or replaced by the successor corporation,
which assumption will be binding on all Participants), (c) a merger in which
the Company is the surviving corporation but after which the stockholders of
the Company immediately prior to such merger (other than any stockholder that
merges, or which owns or controls another corporation that merges, with the
Company in such merger) cease to own their shares or other equity interest in
the Company, (d) the sale of substantially all of the assets of the Company,
or (e) the acquisition, sale, or transfer of more than 50% of the outstanding
shares of the Company by tender offer or similar transaction, any or all
outstanding Awards may be assumed, converted or replaced by the successor
corporation (if any), which assumption, conversion or replacement will be
binding on all Participants.  In the alternative, the successor corporation
may substitute equivalent Awards or provide substantially similar
consideration to Participants as was provided to stockholders (after taking
into account the existing provisions of the Awards).  The successor
corporation may also issue, in place of outstanding Shares of the Company
held by the Participant, substantially similar shares or other property
subject to repurchase restrictions no less favorable to the Participant.  In
the event such successor corporation (if any) refuses to assume or substitute
Awards, as provided above, pursuant to a transaction described in this
Subsection 18.1, such Awards will accelerate in full immediately prior to
such transaction.

              18.2   OTHER TREATMENT OF AWARDS.  Subject to any greater rights
granted to Participants under the foregoing provisions of this Section 18, in
the event of the occurrence of any transaction described in Section 18.1, any
outstanding Awards will be treated as provided in the applicable agreement or
plan of merger, consolidation, dissolution, liquidation, or sale of assets.

              18.3   ASSUMPTION OF AWARDS BY THE COMPANY.  The Company, from
time to time, also may substitute or assume outstanding awards granted by
another company, whether in connection with an acquisition of such other company
or otherwise, by either; (a) granting an Award under this Plan in substitution
of such other company's award; or (b) assuming such award as if it had been
granted under this Plan if the terms of such assumed award could be applied to
an Award granted under this Plan.  Such substitution or assumption will be
permissible if the holder of the substituted or assumed award would have been
eligible to be granted an Award under this Plan if the other company had applied
the rules of this Plan to such grant.  In the event the Company assumes an award
granted by another company, the terms and conditions of such award will remain
unchanged (EXCEPT that the exercise price and the number and nature of Shares
issuable upon exercise of any such option will be adjusted appropriately
pursuant to Section 424(a) of the Code).  In the event the Company elects to
grant a new Option rather than assuming an existing option, such new Option may
be granted with a similarly adjusted Exercise Price.

       19.    ADOPTION AND STOCKHOLDER APPROVAL.  This Plan will become
effective on the date on which the registration statement filed by the
Company with the SEC under the Securities Act registering the initial public
offering of the Company's Common Stock is declared effective by the SEC (the
"EFFECTIVE DATE").  This Plan shall be approved by the stockholders of the
Company (excluding Shares issued pursuant to this Plan), consistent with
applicable laws, within twelve (12) months before or after the date this Plan
is adopted by the Board.  Upon the Effective Date, the Committee may grant
Awards pursuant to this Plan; PROVIDED, HOWEVER, that: (a) no Option may be
exercised prior to initial stockholder approval of this Plan; (b) no Option
granted pursuant to an increase in the number of Shares subject to this Plan
approved by the Board will be exercised prior to the time such increase has
been approved by the stockholders of the Company; and (c) in the event that
stockholder approval of such increase is not obtained within the time period
provided herein, all Awards granted pursuant to such increase will be
canceled, any Shares issued pursuant to any Award granted pursuant to such
increase will be canceled, and any purchase of Shares pursuant to such
increase will be rescinded.

       20.    TERM OF PLAN/GOVERNING LAW.  Unless earlier terminated as provided
herein, this Plan will terminate ten (10) years from the date this Plan is
adopted by the Board or, if earlier, the date of stockholder approval.  This
Plan and all agreements thereunder shall be governed by and construed in
accordance with the laws of the State of Washington.

       21.    AMENDMENT OR TERMINATION OF PLAN.  The Board may at any time
terminate or amend this Plan in any respect, including without limitation
amendment of any form of Award Agreement or instrument to be executed pursuant
to this Plan; PROVIDED, HOWEVER, that the Board will not, without the approval
of the stockholders of the Company, amend this Plan in any manner that requires
such stockholder approval.

       22.    NONEXCLUSIVITY OF THE PLAN.  Neither the adoption of this Plan by
the Board, the submission of this Plan to the stockholders of the Company for
approval, nor any provision of this Plan will be construed as creating any
limitations on the power of the Board to adopt such additional compensation
arrangements as it may deem desirable, including, without limitation, the
granting of stock options and bonuses otherwise than under this Plan, and such
arrangements may be either generally applicable or applicable only in specific
cases.
