                     AGREEMENT AND PLAN OF REORGANIZATION

     THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is entered into
as of May 22, 1998, by and among Asymetrix Learning Systems, Inc., a Washington
corporation ("Asymetrix"), Asymetrix Acquisition Corp., a Delaware corporation
that is wholly-owned subsidiary of Asymetrix ("Merger Sub"), Strategic Systems
Associates, Inc., an Illinois corporation ("SSA"), and Gary A. Johnson, Richard
M. Johnson and Mike Spingola (each of whom is a  stockholder of SSA, and are
collectively referred to herein as the "Principals" and each individual referred
to as a "Principal").

                                    RECITALS

     The parties intend that, subject to the terms and conditions of this
Agreement:

     Merger Sub will merge with and into SSA in a statutory merger, with SSA to
be the corporation surviving the Merger (as defined below), all pursuant to the
terms and conditions of this Agreement and Plan of Merger in the form of Exhibit
A attached hereto (the "Plan of Merger") and the applicable provisions of the
law of the State of  Illinois and the State of Delaware.

     Upon the effectiveness of the Merger, all of the outstanding capital stock
of SSA will be converted into shares of Asymetrix Common Stock, as provided in
this Agreement and the Plan of Merger.  The Merger is intended to be treated as
a tax-free reorganization pursuant to the provisions of Section 368(a)(1)(A) of
the Internal Revenue Code of 1986, as amended (the "Code") by virtue of the
provisions of Section 368(a)(2)(E) of the Code and will be treated as a
"purchase" for accounting purposes.

     NOW, THEREFORE, the parties hereto hereby agree as follows:

1.   CERTAIN DEFINITIONS.  As used in this Agreement, the following terms have
the meanings set forth below:

     1.1  "Asymetrix Common Stock" means the Common Stock of Asymetrix, $0.01
par value per share.

     1.2  "Asymetrix Options" means options exercisable for Asymetrix Common
Stock to be granted to employees of SSA as provided in Section 11.3.

     1.3  "SSA Common Stock" means the Common Stock of SSA, no par value per
share.

     1.4  "Effective Time" means the time and date on which (i) Articles of
Merger (the "Articles of Merger") have been filed with the Illinois Secretary of
State, (ii) a Certificate of Merger (the "Certificate of Merger") conforming to
the requirements of Section 252 of the Delaware General Corporation Law has been
filed with the Delaware Secretary of State and (iii) the Merger becomes
effective under Illinois law and Delaware law.

                                     
<PAGE>
 
     1.5  "Merger" means the statutory merger of Merger Sub with and into SSA in
a reverse triangular merger pursuant to this Agreement and the Plan of Merger.

     Other capitalized terms defined elsewhere in this Agreement and not defined
in this Section 1 have the meanings assigned to such terms in this Agreement.

2.   PLAN OF REORGANIZATION

     2.1  The Merger.  At the Effective Time, Merger Sub will be merged with and
into SSA pursuant to this Agreement, the Articles of Merger and the Certificate
of Merger and in accordance with applicable provisions of the laws of the State
of Illinois and the State of Delaware.  Each share of SSA Common Stock issued
and outstanding immediately prior to the Effective Time will, by virtue of the
Merger and at the Effective Time, and without further action on the part of any
holder thereof, be converted into such number of shares (the "Applicable
Fraction") of Asymetrix Common Stock as is equal to 136,000 shares divided by
the total number of shares of SSA Common Stock issued and outstanding
immediately prior to the Effective Time.

     2.2  Adjustments for Capital Changes.  If, prior to the Effective Time,
Asymetrix or SSA recapitalizes through a split-up of its outstanding shares into
a greater number, or a combination of its outstanding shares into a lesser
number, reorganizes, reclassifies or otherwise changes its outstanding shares
into the same or a different number of shares of other classes (other than
through a split-up or combination of shares provided for in the previous
clause), or declares a dividend on its outstanding shares payable in shares,
securities convertible into shares or other property, then the Applicable
Fraction will be adjusted appropriately.

     2.3  Fractional Shares.  No fractional shares of Asymetrix Common Stock
will be issued in connection with the Merger, but in lieu thereof, the holders
of SSA Common Stock who would otherwise be entitled to receive a fraction of a
share of Asymetrix Common Stock will receive one additional share of Asymetrix
Common Stock.

     2.4  Options; Other Securities.  No shares of Asymetrix Common Stock (or
any other securities of Asymetrix) shall be issued or issuable with respect to
options to purchase SSA Common Stock or with respect to any other equity
securities of SSA (including warrants), other than SSA Common Stock and all such
options or other equity securities shall be canceled at the Effective Time.

     2.5  Effects of the Merger.  At the Effective Time:  (a) the separate
existence of the Merger Sub will cease and Merger Sub will be merged with and
into SSA, and SSA will be the surviving corporation of the Merger, pursuant to
the terms of the Articles of Merger and the Certificate of Merger; (b) the
Articles of Incorporation and Bylaws of SSA will continue unchanged to be the
Articles of Incorporation and Bylaws of the surviving corporation of the Merger;
(c) each share of capital stock of Merger Sub outstanding immediately prior to
the Effective Time will continue to be an identical outstanding share of the
respective surviving corporation; (d) the directors and officers of Asymetrix
shall become the directors and officers of the surviving corporation; (e) each
share of SSA Common Stock outstanding immediately prior

                                      -2-

                                       
<PAGE>
 
to the Effective Time will be converted into the right to receive that number of
shares of Asymetrix Common Stock as provided in Section 2.1; and (f) the Merger
will, from and after the Effective Time, have all of the effects provided by
applicable law.

     2.6  Further Assurances.  Each of SSA and the Principals agree that if, at
any time after the Effective Time, Asymetrix considers or is advised that any
further deeds, assignments or assurances are reasonably necessary or desirable
to vest, perfect or confirm in Asymetrix title to any property or rights of SSA,
Asymetrix and its officers and directors may execute and deliver all such proper
deeds, assignments and assurances and do all other things necessary or desirable
to vest, perfect or confirm title to such property or rights in Asymetrix and
otherwise carry out the purpose of this Agreement, in the name of SSA or
otherwise.

     2.7  Securities Law Compliance.  Asymetrix will issue the shares of
Asymetrix Common Stock in the Merger pursuant to the "private placement"
exemption from registration under Section 4(2) of, or Regulation D promulgated
under, the Securities Act of 1933, as amended (the "Securities Act"), and the
shares received by the Principals in the Merger will therefore be restricted
securities within the meaning of Rule 144 of the Securities Act, and
certificates evidencing such shares will bear a restrictive legend evidencing
that fact.  Asymetrix shall also take any action that is required to be taken
under any applicable state securities or Blue Sky laws in connection with the
issuance of Asymetrix Common Stock in the Merger.  SSA and the Principals shall
furnish to Asymetrix all information known to SSA or the Principals (or
reasonably ascertainable by SSA or the Principals) concerning each of SSA and
the Principals, as may be reasonably requested in connection with any action
contemplated by this Section.

     2.8  Purchase Accounting.  The parties intend that the Merger be treated as
a purchase for accounting purposes.

     2.9  Tax-Free Reorganization.  The parties intend to adopt this Agreement
as a tax-free plan of reorganization and to consummate the Merger in accordance
with the provisions of Section 368(a)(1)(A) of the Code.  The parties believe
that the value of the Asymetrix Common Stock to be received in the Merger is
equal, in each instance, to the value of the SSA Common Stock, to be surrendered
in exchange therefor.  The Asymetrix Common Stock issued in the Merger will be
issued solely in exchange for SSA Common Stock and no other transaction other
than the Merger represents, provides for or is intended to be an adjustment to
the consideration paid for the SSA Common Stock. Unless advised by tax counsel
that doing so is required under applicable law, the parties shall not take a
position on any tax returns inconsistent with this Section 2.9.  In addition,
Asymetrix represents now, and as of the Effective Time, that it presently
intends to continue SSA's historic business or use a significant portion of
SSA's business assets in a business.  At the Effective Time, officers of each of
Asymetrix and SSA shall execute and deliver officers' certificates in the forms
of Exhibits 2.9A and 2.9B attached hereto.  The provisions and representations
contained or referred to in this Section 2.9 shall survive until the expiration
of the applicable statute of limitations.

                                      -3-

3.   REPRESENTATIONS AND WARRANTIES OF SSA AND PRINCIPALS

     Each of the Principals and SSA, jointly and severally, hereby represents
and warrants as follows, except as set forth in the SSA Schedule of Exceptions
(in numbered paragraphs that correspond to the Section numbers below)
simultaneously delivered to Asymetrix with the execution of this Agreement:

     3.1  Organization, Good Standing and Qualification. SSA is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Illinois, has the corporate power and authority to own, operate and
lease its properties and to carry on its business as now conducted and as
proposed to be conducted, and is qualified as a foreign corporation in the
jurisdictions listed in Schedule 3.1 of the SSA Schedule of Exceptions. SSA is
qualified as a foreign corporation in each jurisdiction in which a failure to be
so qualified could reasonably be expected to have a material adverse effect on
the business, operations, financial condition or prospects of SSA (for purposes
of this Section 3 and Section 5, a "Material Adverse Effect").

     3.2  Power, Authorization and Validity.

          3.2.1  SSA and each Principal has the corporate or other right, power,
legal capacity and authority to enter into and perform his, her or its
obligations under this Agreement and all agreements to which SSA or such
Principal is or will be a party that are required to be executed at the Closing
(defined below) pursuant to this Agreement (the "SSA Ancillary Agreements").
The execution, delivery and performance of this Agreement and the SSA Ancillary
Agreements to which SSA is a party have been duly and validly approved and
authorized by the Board of Directors of SSA.  The Merger has been approved by
all of the stockholders of SSA.

          3.2.2  No filing, authorization or approval, governmental or
otherwise, is necessary to enable SSA and the Principals to enter into, and to
perform his, her or its obligations under, this Agreement and the SSA Ancillary
Agreements, except for (a) the filing of the Articles of Merger with the
Illinois Secretary of State, (b) the filing of the Certificate of Merger with
the Delaware Secretary of State, (c) the filing of appropriate documents with
the relevant authorities of other states in which SSA is qualified to do
business, if any, and (d) such filings as may be required to comply with federal
and state securities laws.

          3.2.3  This Agreement and the SSA Ancillary Agreements are, or when
executed by SSA and/or the Principals, as applicable, will be, valid and binding
obligations of SSA and/or the Principals, as applicable, enforceable in
accordance with their respective terms, except as to the effect, if any, of (a)
applicable bankruptcy and other similar laws affecting the rights of creditors
generally and (b) rules of law governing specific performance, injunctive relief
and other equitable remedies; provided, however, that the Articles of Merger and
Certificate of Merger will not be effective until the Effective Time.

     3.3  Capitalization.  As of the date hereof, the authorized capital stock
of SSA consists of 100,000 shares of SSA Common Stock, of which 10,000 shares
are issued and outstanding as of the date hereof.  All issued and outstanding
shares of SSA Common Stock have been duly

                                      -4-

                                       
<PAGE>
 
authorized and validly issued, are fully paid and nonassessable, are not subject
to any right of rescission, and have been offered, issued, sold and delivered by
SSA, in compliance with all registration or qualification requirements (or
applicable exemptions therefrom) of applicable federal and state securities
laws. Schedule 3.3 of the SSA Schedule of Exceptions sets forth a true, correct
and complete list of all holders of SSA Common Stock and the number of shares of
SSA Common Stock held by each such shareholder. There are no options, warrants,
calls, commitments, conversion privileges or preemptive or other rights or
agreements outstanding to purchase or otherwise acquire any of SSA's authorized
but unissued capital stock or any securities convertible into or exchangeable
for shares of SSA capital stock or obligating SSA to grant, extend, or enter
into any such option, warrant, call, commitment, conversion privilege or other
right or agreement, and there is no liability for dividends accrued but unpaid.
There are no voting agreements, rights of first refusal or other restrictions
(other than normal restrictions on transfer under applicable federal and state
securities laws) applicable to any of SSA's outstanding securities. The Buy-Sell
Agreement dated September 15, 1993 and the Shareholders Agreement dated December
31, 1996 among SSA and Gary A. Johnson, Richard M. Johnson and Tim Schorr have
each been terminated and are no further force and effect. SSA is not under any
obligation to register under the Securities Act any of its presently outstanding
securities or any securities that may be subsequently issued. All holders of SSA
Common Stock reside in the States of Illinois and Idaho.

     3.4  Subsidiaries. SSA does not presently own or control, directly or
indirectly, any interest in any other corporation, partnership, trust, joint
venture, association, or other entity.

     3.5  No Violation of Existing Agreements.  Neither the execution and
delivery of this Agreement or any SSA Ancillary Agreement, nor the consummation
of the transactions contemplated hereby or thereby, will conflict with, or (with
or without notice or lapse of time, or both) result in a termination, breach or
violation of, or cause an acceleration or amendment of any obligation under, (a)
any provision of the Articles of Incorporation or Bylaws of SSA, as currently in
effect, (b) any Material Agreement (as defined in Section 3.11) to which SSA is
a party or by which SSA or the Principals or his, her or its assets or
properties are bound, or (c) to the knowledge of SSA and the Principals, any
federal, state, local or foreign judgment, writ, decree, order, statute, rule or
regulation applicable to SSA or the Principals, or their respective assets or
properties, in each case, such that the conflict, termination, breach,
acceleration or amendment would have a Material Adverse Effect.

     3.6  Litigation.  There is no action, proceeding, claim or investigation
pending against SSA or any Principal before any federal, state, municipal,
foreign or other court or administrative agency, department, board or
instrumentality that, if concluded adversely to SSA or a Principal, would have a
Material Adverse Effect, and, to the best of SSA's and the Principals'
knowledge, no such action, proceeding, claim or investigation has been
threatened.  There is, to the best of SSA's and the Principals' knowledge, no
reasonable basis for any stockholder or former stockholder of SSA, or any other
person, firm, corporation or entity, to assert a claim against SSA, any
Principal or Asymetrix based upon: (a) ownership or rights to ownership of any
shares of SSA Common Stock, (b) any rights as or to become a holder of
securities of SSA, including any option or preemptive rights or rights to notice
or to vote, or (c) any rights under any


                                      -5-

agreement among SSA and any of its stockholders or former stockholders or option
holders or former option holders.

     3.7  Taxes.  For purposes of this Section 3.7, the terms "tax" and "taxes"
include all federal, state, local and foreign income, gains, franchise, excise,
property, sales, use, employment, license, payroll, occupation, recording,
value-added or transfer taxes, governmental charges, fees, levies or assessments
(whether payable directly or by withholding), and, with respect to such taxes,
any estimated taxes, interest, penalties, additions to tax and interest on any
such penalties and additions to tax.  For purposes of this Section 3.7, the
terms "Return" and "Returns" include all federal, state, local and foreign tax
returns, estimates, information statements and reports required to be filed by
SSA with respect to its income, assets or operations.

          3.7.1  SSA has or will have filed all Returns for tax periods ending
before the Effective Time, other than where a failure to file a return did not
or would not have a Material Adverse Effect.  All such Returns that have been
filed were (as filed or after timely amendment) true, correct and complete in
all material respects. SSA and the Principals have provided or made available to
Asymetrix copies of all material Returns actually filed by SSA during the three-
year period ending on the date hereof.

          3.7.2  SSA has paid or deposited in full all taxes due and owing or
shown to be due on the Returns filed by SSA (including required estimated tax
payments with respect thereto), except where a failure to pay a tax in full did
not or would not have a Material Adverse Effect.  SSA has established a proper
and adequate accrual or reserve on the SSA Financial Statements (as defined in
below) for all taxes not yet due and owing, whether or not shown or required to
be shown on any Return, except where a failure to establish such an accrual or
reserve did not or would not have a Material Adverse Effect.

          3.7.3  Neither SSA nor any of the Principals is aware of any pending
or threatened claim or assessment in writing with respect to any deficiencies
for any tax against SSA by any taxing authority.  SSA has not executed any
waiver of any statute of limitations relating to taxes or any extension of the
period for the assessment or collection of any tax (other than extensions which
have expired by the Effective Time).  Neither SSA nor any of the Principals has
received any written notification, or is otherwise aware, that any material
issues are currently under audit, examination or review by any taxing authority
regarding SSA.

          3.7.4  There are no material liens, pledges, charges, claims, security
interests or other encumbrances covering the assets of SSA or the Principals and
relating or attributable to taxes, other than for taxes not yet due and payable
and others that do not have a Material Adverse Effect.

          3.7.5  There is no contract, agreement, plan or arrangement, including
but not limited to the provisions of this Agreement, covering any current or
former employee of SSA that, individually or collectively, could give rise to
the payment of any amount with respect to which a deduction would be disallowed
under Sections 280G or 162(m) of the Internal Revenue Code of 1986, as amended
(the "Code").

                                      -6-

                                       
<PAGE>
 
          3.7.6  SSA is not party to a tax sharing or tax allocation agreement,
and SSA does not owe any amount under any such agreement.

          3.7.7  SSA is not or has not at any time been a "United States real
property holding corporation" within the meaning of Section 897(c) of the Code.

          3.7.8  SSA has not filed any consent agreement under Section 341(f) of
the Code or has agreed to have Section 341(f)(2) of the Code apply to any
disposition of a "subsection (f) asset" (as defined in Section 341(f)(4) of the
Code) owned by SSA.

          3.7.9  None of SSA's assets constitute "tax-exempt use property"
within the meaning of Section 168(h) of the Code.

     3.8  Financial Statements. SSA has delivered to Asymetrix as Schedule 3.8
of the SSA Schedule of Exceptions SSA's (a) balance sheet as of December 31,
1997 (the "1997 Balance Sheet") and income statement and statement of cash flows
for the 12 month period then ended (collectively, the "1997 Financial
Statements"), and (b) balance sheet as of March 31, 1998 (the "March 31 Balance
Sheet") and income statement for the three month period then ended
(collectively, the "SSA March Financial Statements") (the 1997 Financial
Statements and the SSA March Financial Statements are collectively referred to
herein as the "SSA Financial Statements").  The SSA Financial Statements (a) are
in accordance with the books and records of SSA, (b) fairly present the
financial condition of SSA at the dates therein indicated and the results of
operations for the periods therein specified, and (c) have been prepared in
accordance with generally accepted accounting principles applied on a consistent
basis, subject, in the case of the SSA March Financial Statements, to normal
recurring year-end adjustments and the absence of any notes thereto. SSA does
not have any debt, liability or obligation of any nature, whether accrued,
absolute, contingent or otherwise, and whether due or to become due, that is not
reflected or reserved against or disclosed in the SSA Financial Statements,
except for those that may have been incurred after the date of the SSA Financial
Statements in the ordinary course of its business, consistent with past practice
and that are not material in amount either individually or collectively.

     3.9  Title to Properties. SSA has good and marketable title to all of its
tangible assets as shown on the March 31 Balance Sheet, free and clear of all
liens, charges, restrictions or encumbrances, other than for taxes not yet due
and payable and others that do not have a Material Adverse Effect.  All
machinery and equipment included in such properties is in good condition and
repair, normal wear and tear excepted, and all leases of real or personal
property to which SSA is a party are fully effective.  To the knowledge of SSA
and each of the Principals, SSA is not in violation of any zoning, building,
safety or environmental ordinance, regulation or requirement or other law or
regulation applicable to the operation of owned or leased properties (the
violation of which would have a Material Adverse Effect), or has received any
notice of such violation with which it has not complied or had waived.

     3.10  Absence of Certain Changes.  Except as set forth on Schedule 3.10,
since March 31, 1998, other than actions required by this Agreement (including,
without limitation, the

                                      -7-

          (a) any change in the financial condition, properties, assets,

obligations and liabilities incurred in the ordinary course of business, which
obligation or liability is in excess of $10,000 individually or $25,000 in the
aggregate;

individually or $25,000 in the aggregate;

          (f) any damage, destruction or loss, whether or not covered by
insurance, which has a Material Adverse Effect;

          (g) any declaration, setting aside or payment of any dividend on, or
the making of any other distribution in respect of, the capital stock of SSA,
any split, combination or recapitalization of the capital stock of SSA or any
direct or indirect redemption, purchase or other acquisition of the capital
stock of SSA;

          (h) any labor dispute or claim of unfair labor practices or, other
than changes in the ordinary course of business, consistent with past practice,

          (i) any declaration or payment of an extraordinary dividend, within
the meaning of Section 1059(c) of the Code;

          (j) any payment or discharge of a lien or liability thereof which lien

<PAGE>
 
          (k) any material transaction with any of its officers, directors,
employees or stockholders or any entity controlled by any of such individuals.

     3.11  Material Agreements, Contracts and Commitments.  Except as set forth
on Schedule 3.11 of the SSA Schedule of Exceptions and other than this Agreement
and the SSA Ancillary Agreements, neither SSA nor any Principal is on the date
hereof a party or subject to any oral or written contracts, obligations,
commitments, plans, leases, instruments, arrangements or licenses which are

equipment manufacturer, value added remarketer or other agreement for the
ongoing distribution of any products or services of SSA ;

          (j) Instrument evidencing or related in any way to indebtedness for
borrowed money by way of direct loan, sale of debt securities, purchase money
obligation, conditional sale, guarantee, or otherwise, except for trade
indebtedness incurred in the ordinary course of business, and except as
disclosed in the SSA Financial Statements;

          (k) Contract containing covenants purporting to limit SSA's freedom to
compete in any line of business in any geographic area; or

          (l) Stock redemption or purchase agreement yet to be performed.

          All Material Agreements constitute valid and enforceable obligations
of the parties thereto (except as to the effect, if any, of (i) applicable
bankruptcy and other similar laws affecting the rights of creditors generally,
(ii) rules of law governing specific performance, injunctive relief and other
equitable remedies, and (iii) the enforceability of provisions requiring
indemnification in connection with the offering, issuance or sale of
securities), and are and will, immediately after the Effective Time, be in full
force and effect.  Neither SSA nor the Principals is, nor, to the best knowledge
of SSA and the Principals, is any other party thereto, in breach or default in
any material respect under the terms of any such Material Agreement.  A copy of
each Material Agreement has been delivered or made available to Asymetrix's
counsel.  Neither SSA nor the Principals is a party to any contract, agreement
or arrangement which has had, or could reasonably be expected to have, a
Material Adverse Effect. SSA has no material liability for renegotiation of
government contracts or subcontracts, if any.

     3.12  Intellectual Property. SSA owns all right, title or interest in, or
has the rights to use, sell or license, all Intellectual Property Rights (as
defined below) necessary or required for the conduct of, or used in, its
business as presently conducted (such Intellectual Property Rights being
hereinafter collectively referred to as the " SSA IP Rights") and such rights to
use, sell or license are reasonably sufficient for the conduct of its business
as presently conducted.  The execution, delivery and performance of this
Agreement and the consummation of the transactions contemplated hereby will not
cause the forfeiture or termination or give rise to a right of forfeiture or
termination of any SSA IP Right or materially impair the right of SSA to use,
sell or license any SSA IP Right or portion thereof.  There are no royalties,
honoraria, fees or other payments payable by SSA to any person by reason of the
ownership, use, license, sale or disposition of any SSA IP Rights.  Except for
matters which would not have a Material Adverse Effect, neither the manufacture,
marketing, license, sale or intended use of any product currently licensed or
sold by SSA (whether on a stand-alone basis or as part of services offered by
SSA) or currently under development by SSA violates any license or agreement
between SSA and any third party or infringes any Intellectual Property Right of
any other party; and, except for matters which would not have a Material Adverse
Effect, there is no pending or, to the best knowledge of

                                     -10-

                                       
<PAGE>
 
SSA and the Principals, threatened claim or litigation contesting the validity,
ownership or right to use, sell, license or dispose of any SSA IP Right; nor, to
the best knowledge of SSA and the Principals without any independent
investigation thereof, is there any basis for any such claim; nor has SSA
received any notice asserting that any SSA IP Right or the proposed use, sale,
license or disposition thereof conflicts or will conflict with the rights of any
other party, nor, to the best knowledge of SSA and the Principals, is there any
basis for any such assertion. SSA has taken all steps that it believes are
reasonable and practicable to safeguard and maintain the secrecy and
confidentiality of, and its proprietary rights in, all material SSA IP Rights.
SSA is not using any Intellectual Property Rights of any past or present
officers, employees or consultants. Schedule 3.12 of the SSA Schedule of
Exceptions contains a list of all applications, registrations, filings and other
formal actions made or taken pursuant to federal, state and foreign laws by SSA
to perfect or protect its interest in SSA IP Rights, including, without
limitation, all patents, patent applications, copyrights, copyright
registrations, trademarks, trademark applications and service marks and all SSA
IP Rights Agreements (except for object code end-user licenses granted to end-
users in the ordinary course of business that permit use of software products
without a right to modify, distribute or sublicense the same). As used herein,
the term "Intellectual Property Rights" shall mean all intellectual property
rights in any jurisdiction in the world, including, without limitation, patents,
patent applications, patent rights, trademarks, trademark applications, trade
names, service marks, service mark applications, copyright, copyright
registrations, licenses, know-how, trade secrets, customer lists, proprietary
processes, formulae and other rights to Software. The term "Software" shall mean
all source and object code, algorithms, architecture, structure, display
screens, layouts, inventions, development tools and all documentation and media
constituting, describing or relating to the above, including, without
limitation, manuals, memoranda and records. The term " SSA IP Rights Agreement"
shall mean any instrument or agreement governing any SSA IP Right.

     3.13  Compliance with Laws. SSA has complied, or prior to the Closing Date
will have complied, and is or will be at the Closing Date in full compliance, in
all material respects, with all applicable laws, ordinances and regulations, and
rules, and all orders, writs, injunctions, awards, judgments and decrees,
applicable to it or to its assets, properties, and business (the violation of
which would have a Material Adverse Effect), including, without limitation: (a)
all applicable federal and state securities laws and regulations, (b) all
applicable federal, state and local laws, ordinances and regulations, and all
orders, writs, injunctions, awards, judgments and decrees, pertaining to (i) the
sale, licensing, leasing, ownership or management of SSA's owned, leased or
licensed real or personal property, products and technical data, and (ii)
employment and employment practices, terms and conditions of employment, and
wages and hours, (c) the Export Administration Act and regulations promulgated
thereunder and all other laws, regulations, rules, orders, writs, injunctions,
judgments and decrees applicable to the export or re-export of controlled
commodities or technical data and (d) the Immigration Reform and Control Act;
provided, however, that this Section 3.13 shall not be deemed to apply to any
matters within the general scope of any other representation in this Section 3.
SSA has received all permits and approvals from, and has made all filings with,
third parties, including government agencies and authorities, that are necessary
in connection with its present business and which, if not received or filed,
would have a Material Adverse Effect.  There are no legal or administrative
proceedings

                                     -11-

                                       
<PAGE>
 
or investigations pending or threatened, that, if enacted or determined
adversely to SSA or any Principal, would result in any Material Adverse Effect.

     3.14  Certain Transactions and Agreements.  None of the executive officers,
directors or affiliates (as that term is defined in Rule 405 under the
Securities Act) of SSA (each, an "Insider") nor any member of their immediate
families is or has been directly or indirectly interested in any contract or
informal arrangement with SSA within the last three years, except for
compensation as an officer, director or employee of SSA.  None of the Insiders
nor any member of their immediate families has any interest in any property,
real or personal, tangible or intangible, including inventions, patents,
copyrights, trademarks or trade names or trade secrets, used in or pertaining to
the business of SSA, except for the normal rights of a stockholder.

     3.15  Employees, ERISA and Other Compliance.

          3.15.1  SSA has no employment contracts or consulting agreements
currently in effect that are not terminable at will (other than agreements with
the sole purpose of providing for the confidentiality of proprietary information
or assignment of inventions).

          3.15.2  SSA (i) has never been and is not now subject to a union
organizing effort, (ii) is not subject to any collective bargaining agreement
with respect to any of its employees, (iii) is not subject to any other
contract, written or oral, with any trade or labor union, employees' association
or similar organization, or (iv) has no current labor dispute.  SSA and the
Principals have no knowledge that a material number of employees intend to leave
the employ of SSA or that any employees intend to leave the employ of SSA and
which departures would prevent SSA from fully performing on schedule any
Customer Agreement.

          3.15.3  Schedule 3.15.3 of the SSA Schedule of Exceptions identifies
each "employee benefit plan," as defined in Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), but excluding
workers' compensation, unemployment compensation and other government-mandated
programs currently or previously maintained, contributed to or entered into by
SSA under which SSA or any ERISA Affiliate (as defined below) thereof has any
present or future obligation or liability (collectively, the " SSA Employee
Plans").  For purposes of this Section 3.15.3, "ERISA Affiliate" shall mean any
entity which is a member of (A) a "controlled group of corporations," as defined
in Section 414(b) of the Code, (B) a group of entities under "common control,"
as defined in Section 414(c) of the Code, or (C) an "affiliated service group,"
as defined in Section 414(m) of the Code, or treasury regulations promulgated
under Section 414(o) of the Code, any of which includes SSA.  Copies of all SSA
Employee Plans (and, if applicable, related trust agreements) and all amendments
thereto and summary plan descriptions thereof (including summary plan
descriptions) have been delivered or made available to Asymetrix or its counsel,
together with the three most recent annual reports (Form 5500, including, if
applicable, Schedule B thereto) prepared in connection with any such SSA
Employee Plan.  All SSA Employee Plans which individually or collectively would
constitute an "employee pension benefit plan," as defined in Section 3(2) of
ERISA (collectively, the "SSA Pension Plans"), are identified as such in
Schedule 3.15.3 of the SSA Schedule of Exceptions.  As of the date hereof, all
contributions due and previously required to be made on or

                                     -12-

                                       
<PAGE>
 
before the date hereof from SSA with respect to any of the SSA Employee Plans
have been made as required under ERISA or have been accrued on the SSA Financial
Statements. To the knowledge of SSA and the Principals, each SSA Employee Plan
has been maintained substantially in compliance with its terms and with the
requirements prescribed by any and all statutes, orders, rules and regulations,
including, without limitation, ERISA and the Code, which are applicable to such
SSA Employee Plans.

          3.15.4  No "prohibited transaction," as defined in Section 406 of
ERISA or Section 4975 of the Code, has occurred with respect to any SSA Employee
Plan which is covered by Title I of ERISA which would result in a material
liability to SSA taken as a whole, excluding transactions effected pursuant to a
statutory or administrative exemption.  Nothing done or omitted to be done and
no transaction or holding of any asset under or in connection with any SSA
Employee Plan has made or will make SSA or any officer or director of SSA
subject to any material liability under Title I of ERISA or liable for any
material tax (as defined in Section 2.7) or penalty pursuant to Sections 4972,
4975, 4976 or 4979 of the Code or Section 502 of ERISA.

          3.15.5  Any SSA Pension Plan which is intended to be qualified under
Section 401(a) of the Code (an "SSA 401(a) Plan") has received a favorable
determination from the Internal Revenue Service as to its qualifications, and
SSA and the Principals are not aware of any reason why such determination may
not be relied upon by such plan.  SSA and the Principals have delivered or made
available to Asymetrix or its counsel a true, correct and complete copy of the
most recent Internal Revenue Service determination letter with respect to each
SSA 401(a) Plan.

          3.15.6  Schedule 3.15.6 of the SSA Schedule of Exceptions lists each
employment, severance or other similar contract (written or oral), arrangement
or policy and each plan or arrangement providing for insurance coverage
(including any self-insured arrangements), workers' benefits, vacation benefits,
severance benefits, disability benefits, death benefits, hospitalization
benefits, retirement benefits, deferred compensation, profit-sharing, bonuses,
stock options, stock purchase, phantom stock, stock appreciation or other forms
of incentive compensation or post-retirement insurance, compensation or benefits
for employees, consultants or directors, but excluding workers' compensation,
unemployment compensation and other government-mandated programs currently or
previously maintained, which (A) is not an SSA Employee Plan, (B) is entered
into, maintained or contributed to, as the case may be, by SSA and (C) covers
any employee or former employee of SSA.  Such contracts, plans and arrangements
as are described in this Section 3.15.6 are herein referred to collectively as
the "SSA Benefit Arrangements."  Each SSA Benefit Arrangement has been
maintained in substantial compliance with its terms and with the requirements
prescribed by any and all statutes, orders, rules and regulations which are
applicable to such SSA Benefit Arrangement. SSA has delivered or made available
to Asymetrix or its counsel a complete and correct copy or description of each
SSA Benefit Arrangement.

          3.15.7  SSA has timely provided to individuals entitled thereto all
required notices and coverage pursuant to Section 4980B of the Code and the
Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"),
with respect to any "qualifying event" (as

                                     -13-

                                       
<PAGE>
 
defined in Section 4980B(f)(3) of the Code) under any SSA Employee Plan
occurring prior to and including the Closing Date, and no material Tax payable
on account of Section 4980B of the Code has been incurred with respect to any
current or former employees (or their beneficiaries) of SSA.

          3.15.8  No benefit payable or which may become payable by SSA pursuant
to any SSA Employee Plan or any SSA Benefit Arrangement or as a result of or
arising under this Agreement shall constitute an "excess parachute payment" (as
defined in Section 280G(b)(1) of the Code) which is subject to the imposition of
an excise Tax under Section 4999 of the Code or which would not be deductible by
reason of Section 280G of the Code.

          3.15.9  To the knowledge of SSA and the Principals and except for
matters which would not have a Material Adverse Effect, no employee of SSA is in
violation of any term of any employment contract, patent disclosure agreement,
noncompetition agreement, or any other contract or written agreement, or any
restrictive covenant contained in any such agreement relating to the right of
any such employee to be employed thereby, or to use trade secrets or proprietary
information of others, and the employment of such employees does not subject SSA
to any material liability.

          3.15.10  A list of all employees, officers and consultants of SSA and
their current compensation, bonus plans, commission plans, vacation rights and
severance rights is set forth on Schedule 3.15.10 of the SSA Schedule of
Exceptions. SSA is currently paying all amounts that are currently required to
be paid to such parties shown in such Schedule.

          3.15.11  SSA is not a party to any (a) agreement with any executive
officer or other key employee of SSA (i) the benefits of which are contingent,
or the terms of which are materially altered, upon the occurrence of a
transaction involving SSA in the nature of any of the transactions contemplated
by this Agreement and the Plan of Merger, (ii) providing any term of employment
or compensation guarantee, or (iii) providing severance benefits or other
benefits after the termination of employment of such employee regardless of the
reason for such termination of employment, or (b) agreement or plan, including,
without limitation, any stock option plan, stock appreciation rights plan or
stock purchase plan, any of the benefits of which will be materially increased,
or the vesting of benefits of which will be materially accelerated, by the
occurrence of any of the transactions contemplated by this Agreement and the
Plan of Merger or the value of any of the benefits of which will be calculated
on the basis of any of the transactions contemplated by this Agreement and the
Plan of Merger. SSA is not obligated to make any "excess parachute payment" (as
defined in Section 280G(b)(1) of the Code), nor will any excess parachute
payment be deemed to have occurred as a result of or arising out of the Merger.

          3.15.12  Any employment agreements, consulting agreements, letter
agreements or other agreements between SSA and any of the Principals have been
terminated and are of no further force and effect, including without limitation
the following: Employment Agreement dated December 31, 1996 with Gary A.
Johnson;  Consulting Contract dated January 7, 1997 with Gary A. Johnson;
Employment Agreement dated December 31, 1996 with Richard M.

Johnson; Employment Agreement dated January 31, 1997 with Mike Spingola; and
Letters of Agreement dated January 23, 1998 with each of Richard Johnson and
Mike Spingola.

     3.16  Corporate Documents. SSA has made available to Asymetrix for
examination all documents and information listed in the SSA Schedule of
Exceptions or other exhibits called for by this Agreement or which have been
requested by Asymetrix's counsel, including, without limitation, the following:
(a) copies of the Articles of Incorporation and Bylaws of SSA as currently in
effect; (b) the Minute Book containing all records of all proceedings, consents,
actions and meetings of the stockholders, the board of directors and any
committees thereof of SSA; (c) the stock ledger and journal reflecting all stock
issuances and transfers of SSA; (d) all material permits, orders, and consents
issued by any regulatory agency with respect to SSA, or any securities of SSA,
and all applications for such permits, orders, and consents; and (e) copies or
forms of all stock purchase agreements, warrants, option plans, grants and
exercise agreements and, where forms of agreements are provided rather than
copies of the signed documents, a true and complete list showing the names of
the security holder, numbers of shares, exercise or purchase prices, grant
dates, vesting dates, exercise dates, expiration dates and all other relevant
data necessary for Asymetrix to issue the Asymetrix Common Stock.

     3.17  No Brokers.  Neither SSA nor any of the Principals is obligated for
the payment of fees or expenses of any investment banker, broker or finder in
connection with the origin, negotiation or execution of this Agreement or the
SSA Ancillary Agreements or in connection with any transaction contemplated
hereby or thereby.  Except as otherwise provided in this Agreement, SSA and each
Principal will pay only its own expenses, if any, incurred in connection with
this Agreement and the transactions contemplated herein.

     3.18  Disclosure.  To the knowledge of SSA and the Principals, neither this
Agreement, its exhibits and schedules, nor any of the certificates or documents
to be delivered by SSA or the Principals to Asymetrix under this Agreement,
taken together, contains any untrue statement of a material fact or omits to
state any material fact necessary in order to make the statements contained
herein and therein, in light of the circumstances under which such statements
were made, not misleading.

     3.19  Insurance. SSA maintains and at all times during the prior three
years has maintained fire and casualty, general liability, business interruption
and product liability insurance which it believes to be reasonably prudent for
similarly sized and similarly situated businesses.  A list of all such insurance
is set forth on Schedule 3.19 of the SSA Schedule of Exceptions.

     3.20  Environmental Matters.

          3.20.1  During the period that SSA has leased or owned its properties
or owned or operated any facilities, there have been no disposals or releases of
Hazardous Materials (as defined below) by SSA, or to SSA's and the Principals'
knowledge, by others, on, from or under such properties or facilities, the
liability for which would have a Material Adverse Effect.  SSA and the
Principals have no knowledge of any presence, generation, manufacturing,
disposals or releases of Hazardous Materials on, from or under any of such
properties or facilities, which may

                                     -15-

                                       
<PAGE>
 
have occurred prior to SSA having taken possession of any of such properties or
facilities, the liability for which would have a Material Adverse Effect. For
the purposes of this Agreement, the terms "disposal" and "release" shall have
the definitions assigned thereto by the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, 42 U.S.C. (S) 9601 et seq., as amended
("CERCLA"). For the purposes of this Agreement, "Hazardous Materials" shall mean
any hazardous or toxic substance, material or waste which is or becomes prior to
the Closing Date regulated under, or defined as a "hazardous substance,"
"pollutant," "contaminant," "toxic chemical," "hazardous material," "toxic
substance" or "hazardous chemical" under (i) CERCLA; (ii) the Emergency Planning
and Community Right-to-Know Act, 42 U.S.C. (S) 1801 et seq.; (iii) the Toxic
Substance Control Act, 15 U.S.C. (S) 2601 et seq.; (iv) the Occupational Safety
and Health Act of 1970, 29 U.S.C. (S) 651 et seq.; (v) any applicable federal,
state or local statute or ordinance that has a scope or purpose similar to those
identified above; or (vi) regulations promulgated under any of the laws or
statutes identified above.

          3.20.2  None of the properties or facilities of SSA is in material
violation of any federal, state or local law, ordinance, regulation or order
relating to industrial hygiene or to the environmental conditions on, under or
about such properties or facilities, including, but not limited to, soil and
ground water condition.  During the time that SSA has owned or leased its
properties and facilities, neither SSA nor, to SSA's and the Principals'
knowledge, any third party, has used, generated, manufactured or stored on,
under or about such properties or facilities or transported to or from such
properties or facilities any Hazardous Materials except in substantial
accordance with applicable environmental laws.

          3.20.3  During the time that SSA has owned or leased its respective
properties and facilities, there has been no litigation brought or, to the
knowledge of SSA and the Principals, threatened against SSA by, or any
settlement reached by SSA with, any party or parties alleging the presence,
disposal, release or threatened release of any Hazardous Materials on, from or
under any of such properties or facilities.

     3.21  Books and Records.  The books, records and accounts of SSA (a) are in
all material respects true, complete and correct, (b) have been maintained in
accordance with good business practices on a basis consistent with prior years,
(c) are stated in reasonable detail and accurately and fairly reflect the
material transactions and dispositions of the assets of SSA, and (d) accurately

     3.22  Certain Dispositions After Effective Time.  None of the Principals
has any present plan or intention, or any binding commitment, to dispose, after
the Effective Time, of an amount of Asymetrix Common Stock that would cause the
Principals, in the aggregate, to have disposed of such stock in an amount equal
in value to 50% or more of the value of SSA Common Stock outstanding immediately
prior to the Effective Time.

Asymetrix does not owe any amount under any such agreement.

          (g) any declaration, setting aside or payment of any dividend on, or
the making of any distribution in respect of, its capital stock, or any split,
combination or recapitalization of its capital stock or any direct or indirect
redemption, purchase or other acquisition of its capital stock, including,
without limitation, any extraordinary dividend within the meaning of Section
1059(c) of the Code;

          (h) any labor dispute or claim of unfair labor practices;

          (i) any payment or discharge of a lien or liability thereof which lien

directors, employees or stockholders or any entity controlled by any of such

     4.11  Material Agreements, Contracts and Commitments.  All oral or written
contracts, obligations, commitments, plans, leases, instruments, arrangements or
licenses which are material to the business of Asymetrix and its subsidiaries
taken as a whole (for purposes of this Section 4.11, a "Material Agreement")
constitute valid and enforceable obligations of the parties thereto (except as
to the effect, if any, of (i) applicable bankruptcy and other similar laws
affecting the rights of creditors generally, (ii) rules of law governing
specific performance, injunctive relief and other equitable remedies, and (iii)
the enforceability of provisions requiring indemnification in connection with
the offering, issuance or sale of securities); and are in full force and effect.
Asymetrix is not, nor, to the best knowledge of Asymetrix, is any other party
thereto, in breach or default in any material respect under the terms of any
such Material Agreement.  A copy of each Material Agreement has been made
available for inspection to counsel for SSA and the Principals.  Asymetrix is
not a party to any contract or arrangement which, in the absence of a breach by

have a Material Adverse Effect.  Asymetrix does not have any material liability
for renegotiation of government contracts or subcontracts, if any.

interest in, or has the rights to use, sell or license, all Intellectual
Property Rights necessary or required for the conduct of, or used in, its
business as presently conducted (such Intellectual Property Rights being
hereinafter collectively referred to as the "Asymetrix IP Rights") and such
rights to use, sell or license are reasonably sufficient for the conduct of its
business as presently conducted.  Except for matters which would not have a
Material Adverse Effect, neither the manufacture, marketing, license, sale or
intended use of any product currently licensed or sold by Asymetrix or currently
under development by Asymetrix violates any license or agreement between
Asymetrix and any third party or infringes any Intellectual Property Right of
any other party; and, except for matters which would not have a Material Adverse
Effect, there is no pending or, to the best knowledge of Asymetrix, threatened
claim or litigation contesting the validity, ownership or right to use, sell,
license or dispose of any Asymetrix IP Right; nor, to the best knowledge of
Asymetrix without any independent investigation thereof, is there any basis for
any such claim; nor has Asymetrix received any notice asserting that any
Asymetrix IP Right or the proposed use,

                                     -22-

                                       
<PAGE>
 
sale, license or disposition thereof conflicts or will conflict with the rights
of any other party, nor, to the best knowledge of Asymetrix, is there any basis
for any such assertion.

     4.13  Compliance with Laws.  Asymetrix and Merger Sub have complied, or
prior to the Closing Date will have complied, and are or will be at the Closing
Date in full compliance, in all material respects, with all applicable laws,
ordinances and regulations, and rules, and all orders, writs, injunctions,
awards, judgments and decrees, applicable to it or to its assets, properties,
and business (the violation of which would have a Material Adverse Effect),
including, without limitation: (a) all applicable federal and state securities
laws and regulations, (b) all applicable federal, state and local laws,
ordinances and regulations, and all orders, writs, injunctions, awards,
judgments and decrees, pertaining to (i) the sale, licensing, leasing, ownership
or management of Asymetrix's owned, leased or licensed real or personal
property, products and technical data, and (ii) employment and employment
practices, terms and conditions of employment, and wages and hours, (c) the
Export Administration Act and regulations promulgated thereunder and all other
laws, regulations, rules, orders, writs, injunctions, judgments and decrees
applicable to the export or re-export of controlled commodities or technical
data and (d) the Immigration Reform and Control Act.  Asymetrix has received all
permits and approvals from, and has made all filings with, third parties,
including government agencies and authorities, that are necessary in connection
with its present business and which, if not received or filed, would have a
Material Adverse Effect.  There are no legal or administrative proceedings or
investigations pending or threatened, that, if enacted or determined adversely
to Asymetrix, would result in any Material Adverse Effect.

directors or affiliates (other than (i) SOFTVEN No. 2 Investment Enterprises
Partnership, or its designated director, (ii) the designated director of the
former stockholders of Aimtech corporation (iii) Kevin Oakes or (iv) Cynthia
Boyd and James Boyd) of Asymetrix (each, an "Asymetrix Insider") nor any member
of their immediate families is or has been directly or indirectly interested in
any contract or informal arrangement with Asymetrix within the last twelve (12)
months, except for compensation as an officer, director or employee of
Asymetrix.  None of the Asymetrix Insiders nor any member of their immediate
families has any interest in any property, real or personal, tangible or
intangible, including inventions, patents, copyrights, trademarks or trade names
or trade secrets, used in or pertaining to the business of Asymetrix, except for
the normal rights of a shareholder.

     4.15  Governmental Consents.  No consent, approval, order or authorization
of, or registration, qualification, designation, declaration or filing with, any
federal, state or local governmental authority on the part of Asymetrix or
Merger Sub is required in connection with the consummation of the transactions
contemplated by this Agreement, except for such qualifications or filings under
the Securities Act and the regulations thereunder and all other applicable
securities laws as may be required in connection with the transactions
contemplated by this Agreement.  All such qualifications and filings will, in
the case of qualifications, be effective on the Closing and will, in the case of

employment, employment practices, wages, employee benefit plans as defined in
Section 3(3) of ERISA, hours, and terms and conditions of employment, including,
but not limited to, employee compensation matters, ERISA and the Code.

           4.16.3  To the knowledge of Asymetrix and except for matters which
would not have a Material Adverse Effect, no employee of Asymetrix is in
violation of any term of any employment contract, patent disclosure agreement,
noncompetition agreement, or any other contract or written agreement, or any
restrictive covenant contained in any such agreement relating to the right of
any such employee to be employed thereby, or to use trade secrets or proprietary
information of others, and the employment of such employees does not subject

commitment or arrangement with any labor union, employees association or similar
organization, and to Asymetrix's best knowledge, no labor union, employees
association or similar organization has requested, sought or attempted to
represent any employees, representatives or agents of Asymetrix.  There is no
strike or other labor dispute involving Asymetrix pending nor, to Asymetrix's
best knowledge, threatened, nor is Asymetrix aware of any labor organization
activity involving its employees.

Asymetrix has no knowledge of any presence, generation, manufacturing, disposals
or releases of Hazardous Materials on, from or under any of such properties or

material violation of any federal, state or local law, ordinance, regulation or
order relating to industrial hygiene or to the environmental conditions on,

(c) of this subsection 11.2.1 shall be $1,000,000 (the "Cap"), provided,
however, that any indemnification obligations arising under this subsection
11.2.1 which result from intentional fraud or willful miscount shall be excluded
from the calculation of the Cap and the Cap shall not

                                      -36-
<PAGE>
 
otherwise apply to any indemnification obligations arising under this subsection
11.2.1 which result from intentional fraud or willful misconduct.

          11.2.2  The indemnification provided for in paragraphs (a), (b) and
(c) of subsection 11.2.1 shall not apply unless and until the aggregate Damages
for which one or more Asymetrix Indemnified Persons seeks indemnification under
such paragraphs (a), (b) and (c), exclusive of legal fees, exceeds $50,000 (the
"Basket") and then only to the extent that aggregate Damages exceed the Basket.
The Basket shall not apply to any Damages arising from the breach of the
representations and warranties set forth in Section 3.7.  Asymetrix will use
commercially resaonable efforts to obtain recoveries under all applicable
insurance policies for all Damages. Except for intentional fraud or willful
misconduct, the remedies set forth in this Section shall be the exclusive
remedies of the Asymetrix Indemnified Persons against any of the Principals.

          11.2.3  Subject to the limitations set forth in this Section 11,
Asymetrix will indemnify and hold harmless the Principals (collectively, the
"SSA Indemnified Persons") from and against any and all Damages:

          (a) arising out of any misrepresentation or breach of or default in
connection with any of the representations, warranties and covenants given or
made by Asymetrix in this Agreement or in any certificate, document or
instrument delivered by or on behalf of Asymetrix pursuant hereto; or

          (b) resulting from any failure on the part of Asymetrix to issue to
the Principals good, valid and marketable title to the Asymetrix Common Stock as
provided in this Agreement, free and clear of all liens, claims, pledges,
options, adverse claims, assessments or charges of any nature whatsoever.

          Asymetrix's maximum aggregate liability under paragraphs (a) and (b)
of this subsection 11.2.3 shall be $1,000,000.

          11.2.4  Any Asymetrix Indemnified Person or any SSA Indemnified Person
seeking indemnification hereunder shall give prompt written notification to the
Principals (in the case of indemnification sought by the Asymetrix Indemnified
Person) or to Asymetrix (in the case of indemnification sought by a SSA
Indemnified Person) (as applicable, the "Indemnification Representative") of the
commencement of any action, suit or proceeding relating to a third party claim
for which indemnification pursuant to this Section 11 may be sought; provided,
however, that no delay on the part of the Indemnified Person in providing such
notice shall relieve the Principals or Asymetrix, as the case may be, of any
liability or obligation hereunder except to the extent of any damage or
liability caused by or arising out of such failure.  Within 20 days after
delivery of such notification, the Indemnification Representative may, upon
written notice thereof to the Indemnified Person, assume control of the defense
of such action, suit or proceeding with counsel reasonably satisfactory to the
Indemnified Person, provided that the Indemnification Representative
acknowledges in writing to the Indemnified Person that any damages, fines, costs
or other liabilities that may be assessed against the Indemnified Person in
connection with such action, suit or proceeding constitute Damages for which the
Indemnified Person shall be entitled to indemnification pursuant to this Section
11.  If the Indemnification

                                      -37-
<PAGE>
 
Representative does not so assume control of such defense, the Indemnified
Person shall control such defense. The party not controlling such defense may
participate therein at its own expense; provided that if the Indemnification
Representative assumes control of such defense and the Indemnified Person
reasonably concludes that the indemnifying parties and the Indemnified Person
have conflicting interests or different defenses available with respect to such
action, suit or proceeding, the reasonable fees and expenses of counsel to the
Indemnified Person shall be considered "Damage" for purposes of this Agreement.
The party controlling such defense shall keep the other party advised of the
status of such action, suit or proceeding and the defense thereof and shall
consider in good faith recommendations made by the other party with respect
thereto. The Indemnified Person shall not agree to any settlement of such
action, suit or proceeding without the prior written consent of the
Indemnification Representative.

          11.2.5  Treatment of Indemnity Payments.  Any payment made to an
Indemnified Person pursuant to this Section 11 shall be treated as a reduction
in the merger consideration.

     11.3  Employee Stock Options.  Asymetrix shall take all action necessary to
reserve for issuance under the Asymetrix 1998 Equity Incentive Plan, and as soon
as reasonably practicable following the closing of the initial public offering
of Asymetrix Common Stock, grant Asymetrix Options to purchase the number of
shares of Asymetrix Common Stock as set forth on Schedule 11.3 to employees of
SSA who become Asymetrix employees. The grant of such options to any particular
employee shall be contingent upon such employee executing Asyemtrix's standard
form of Employee Invention, Confidentiality, Nonraiding and Noncompetition
Agreement.

12.  MISCELLANEOUS

     12.1  Governing Law.  The internal laws of the State of Washington
(irrespective of its conflict of law principles) will govern the validity of
this Agreement, the construction of its terms, and the interpretation and
enforcement of the rights and duties of the parties hereto.

     12.2  Assignment; Binding Upon Successors and Assigns. Neither party hereto
may assign any of its rights or obligations hereunder without the prior written
consent of the other party hereto and any attempt to do so will be void. This
Agreement will be binding upon and inure to the benefit of the parties hereto
and their respective successors and permitted assigns.

     12.3  Severability.  If any provision of this Agreement, or the application
thereof, will for any reason and to any extent be invalid or unenforceable, the
remainder of this Agreement and application of such provision to other persons
or circumstances will be interpreted so as reasonably to effect the intent of
the parties hereto.  The parties further agree to replace such void or
unenforceable provision of this Agreement with a valid and enforceable provision
that will achieve, to the extent possible, the economic, business and other
purposes of the void or unenforceable provision.

     12.4  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which will be an original as regards any party whose
signature appears thereon and all of

                                      -38-
<PAGE>
 
which together will constitute one and the same instrument. This Agreement will
become binding when one or more counterparts hereof, individually or taken
together, will bear the signatures of all parties reflected hereon as
signatories. Facsimile copies of such counterparts are acceptable.

     12.5  Other Remedies.  Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby or by law on such party,
and the exercise of any one remedy will not preclude the exercise of any other.

     12.6  Amendment and Waivers.  Any term or provision of this Agreement may
be amended, and the observance of any term of this Agreement may be waived
(either generally or in a particular instance and either retroactively or
prospectively) only by a writing signed by the party to be bound thereby. The
waiver by a party of any breach hereof or default in the performance hereof will
not be deemed to constitute a waiver of any other default or any succeeding
breach or default. The Agreement may be amended by the parties hereto at any
time before or after approval of the shareholders of SSA but, after such
approval, no amendment will be made which by applicable law requires the further
approval of the shareholders of SSA without obtaining such further approval.

     12.7  No Waiver.  The failure of any party to enforce any of the provisions
hereof will not be construed to be a waiver of the right of such party
thereafter to enforce such provisions.

     12.8  Expenses.  Each party will bear its respective expenses and fees of
its own accountants, attorneys and other professionals incurred with respect to
this Agreement and the transactions contemplated hereby, except that the
Principals shall pay such expenses and fees of SSA to the extent that they
exceed $20,000.

     12.9  Attorneys' Fees.  Should suit be brought to enforce or interpret any
part of this Agreement, the prevailing party will be entitled to recover, as an
element of the costs of suit, reasonable attorneys' fees to be fixed by the
court (including without limitation, costs, expenses and fees on any appeal).
The prevailing party will be entitled to recover its costs of suit, regardless
of whether such suit proceeds to final judgment.

     12.10  Notices.  Any notice or other communication required or permitted to
be given under this Agreement will be in writing, will be delivered personally,
by registered or certified mail, postage prepaid, by confirmed facsimile or by
nationally recognized courier service, and will be deemed given upon delivery,
if delivered personally, or five days after deposit in the mails, if mailed, or
upon receipt if delivered by confirmed facsimile or by nationally recognized
courier service, to the following addresses:

or to such other address as a party may have furnished to the other parties in
writing pursuant to this Section 12.10.

     12.11  Construction of Agreement.  This Agreement has been negotiated by
the respective parties hereto and their attorneys and the language hereof will
not be construed for or against either party.  A reference to a Section or an
exhibit will mean a Section in, or exhibit to, this Agreement unless otherwise
explicitly set forth.  The titles and headings herein are for reference purposes
only and will not in any manner limit the construction of this Agreement which
will be considered as a whole.

     12.12  No Joint Venture.  Nothing contained in this Agreement will be
deemed or construed as creating a joint venture or partnership between any of
the parties hereto.  No party is by virtue of this Agreement authorized as an
agent, employee or legal representative of any other party.  No party will have
the power to control the activities and operations of any other and their

                                      -40-
<PAGE>
 
status is, and at all times, will continue to be, that of independent
contractors with respect to each other. No party will have any power or
authority to bind or commit any other. No party will hold itself out as having
any authority or relationship in contravention of this Section.

     12.13  Further Assurances.  Each party agrees to cooperate fully with the
other parties and to execute such further instruments, documents and agreements
and to give such further written assurances as may be reasonably requested by
any other party to evidence and reflect the transactions described herein and
contemplated hereby and to carry into effect the intents and purposes of this
Agreement.

     12.14  Absence of Third Party Beneficiary Rights.  No provisions of this
Agreement are intended, nor will be interpreted, to provide or create any third
party beneficiary rights or any other rights of any kind in any client,
customer, affiliate, stockholder, partner or any party hereto or any other
person or entity unless specifically provided otherwise herein, and, except as
so provided, all provisions hereof will be personal solely between the parties
to this Agreement.

     12.15  Public Announcement.  Upon execution of the Agreement by all
parties, and until the consummation of the Merger, all press releases and other
public communications shall be made by the parties only with the mutual consent
of the Principals, SSA and Asymetrix.

     12.16  Confidentiality.  Asymetrix, SSA and the Principals each recognize
that they have received and will receive confidential information concerning the
other during the course of the negotiations and preparations for the Merger.
Accordingly, each party agrees (a) to use its respective best efforts to prevent
the unauthorized disclosure of any confidential information concerning the other
that was or is disclosed during the course of such negotiations and
preparations, and is clearly designated in writing as confidential at the time
of disclosure, and (b) to not make use of or permit to be used any such
confidential information other than for the purpose of effectuating the Merger
and related transactions.  The obligations of this Section will not apply to
information that (i) is or becomes part of the public domain, (ii) is disclosed
by the disclosing party to third parties without restrictions on disclosure,
(iii) is received by the receiving party from a third party without breach of a
nondisclosure obligation to the other party or (iv) is required to be disclosed
by law.  If this Agreement is terminated, all copies of documents containing
confidential information shall be returned by the receiving party to the
disclosing party.  Notwithstanding Section 12.17, this provision does not
supersede or replace any other confidentiality or non-disclosure agreement
between the parties, all of which shall remain in full force an effect in
accordance with their terms.

     12.17  Entire Agreement.  This Agreement and the exhibits hereto constitute
the entire understanding and agreement of the parties hereto with respect to the
subject matter hereof and supersede all prior and contemporaneous agreements or
understandings, inducements or conditions, express or implied, written or oral,
between the parties.  The express terms hereof control and supersede any course
of performance or usage of the trade inconsistent with any of the terms hereof.
