                   SERIES A PREFERRED STOCK PURCHASE AGREEMENT

         THIS SERIES A PREFERRED STOCK PURCHASE AGREEMENT (the "Agreement") is
entered into as of August 20, 1998, by and among INTERACTIVE KNOWLEDGE, INC., a
Delaware corporation (the "Company"), Clark Ellis, Henry Vellandi, and Tim
Schiewe (collectively, the "Founders" and each individually as a "Founder") and
each of those persons and entities, severally and not jointly, whose names are
set forth on the Schedule of Purchasers attached hereto as Exhibit A (which
persons and entities are hereinafter collectively referred to as "Purchasers"
and each individually as a "Purchaser").

                                    RECITALS

         WHEREAS, the Company has authorized the sale and issuance of an
aggregate of five million one hundred twenty-five thousand (5,125,000) shares,
$.001 par value per share, of its Series A Preferred Stock (the "Series A
Stock");

         WHEREAS, Purchasers desire to (i) purchase an aggregate of three
million seventy-five thousand (3,075,000) shares of Series A Stock ("the
Shares") on the date hereof and (ii) have an option to purchase an additional
two million fifty thousand (2,050,000) shares of Series A Stock at the Second
Closing (as defined below) on the terms and conditions set forth herein; and

         WHEREAS, the Company desires to issue and sell the Shares to Purchasers
on the terms and conditions set forth herein and to grant Purchasers the option
referenced above.

         NOW, THEREFORE, in consideration of the foregoing recitals and the
mutual promises hereinafter set forth, the parties hereto agree as follows:

         1.       AGREEMENT TO SELL AND PURCHASE.

                  1.1 AUTHORIZATION OF SERIES A STOCK. On or prior to the
Company shall have authorized (i) the sale and issuance to Purchasers of the
Series A Stock and (ii) the issuance of such shares of Common Stock to be issued
upon conversion of the Series A Stock (the "Conversion Shares"). The Series A
Stock and the Conversion Shares shall have the rights, preferences, privileges
and restrictions set forth in the Restated Certificate of Incorporation of the
Company in the form attached hereto as Exhibit B (the "Restated Certificate").

                  1.2 SALE AND PURCHASE. Subject to the terms and conditions

         2.       CLOSING, DELIVERY AND PAYMENT.

                  2.1 CLOSING. The initial closing of the sale and purchase of
the Shares under this Agreement (the "First Closing") shall take place on August
20, 1998 at the offices of Holme Roberts & Owen, LLP, 1401 Pearl Street,
Boulder, Colorado or at such other time or place as the Company and Purchasers
may mutually agree. The closing of the sale and purchase of the shares of Series
A Stock as set forth in Section 2.3 below shall take place at such time and
place as the Company and Purchasers participating therein shall mutually agree
(the "Second Closing") (the First Closing and the Second Closing are
collectively referred to herein as a "Closing" and each such date is referred to
as a "Closing Date").

                  2.2 DELIVERY. At each Closing, subject to the terms and
conditions hereof, the Company will deliver to the Purchasers certificates
representing the number of Shares to be purchased at the Closing by each
Purchaser, against payment of the purchase price therefor by check, wire
transfer made payable to the order of the Company, cancellation of indebtedness
or any combination of the foregoing.

                  2.3 SUBSEQUENT SALES OF SHARES. Contingent upon the attainment
by the Company of certain Milestones, as defined in Exhibit C attached hereto,
as determined solely in the reasonable discretion of each Purchaser, each
Purchaser shall have the option to purchase from the Company, severally and not
jointly, the number of shares of Series A Stock set forth opposite such
Purchaser's name under the heading "Second Closing" on Exhibit A. In the event
that the Company has not, in the reasonable sole discretion of the Purchasers,
attained the Milestones on or prior to January 4, 1999, the Purchasers shall
have no further obligation to acquire any shares of Series A Stock. Each
Purchaser may, at its sole option at any time on or prior to January 4, 1999,
purchase the number of shares of Series A Stock set forth opposite such
Purchaer's name under the heading "Second Closing" on Exhibit A, whether or not
the Company has attained the Milestones. All such sales shall be made on the
terms and conditions set forth in this Agreement, including, without limitation,
satisfaction of the conditions to closing set forth in Section 6 below. Any
shares of Series A Stock sold pursuant to this Section 2.3 shall be deemed to be
"Shares" for all purposes under this Agreement and any purchasers thereof shall
be deemed to be "Purchasers" for all purposes under this Agreement.

         3.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         Except as set forth on a Schedule of Exceptions delivered by the
Company to the Purchasers at the First Closing or at the Second Closing, as the
case may be, the Company hereby represents and warrants to each Purchaser as of
the date of this Agreement as follows:

                  3.1 ORGANIZATION, GOOD STANDING AND QUALIFICATION. The Company
is a corporation duly organized, validly existing and in good standing under the
laws of the State of Delaware. The Company has all requisite corporate power and
authority to own and operate its properties and assets, to execute and deliver
this Agreement, the Investors' Rights Agreement in the form attached hereto as
Exhibit D (the "Investors' Rights Agreement") and the Stockholders Agreement in
the form attached hereto as Exhibit E (the "Stockholders Agreement")

                                        2
<PAGE>   6

(collectively, the "Related Agreements"), to issue and sell the Shares and to
issue the Conversion Shares and to carry out the provisions of this Agreement,
the Related Agreements and the Restated Certificate and to carry on its business
as presently conducted and as presently proposed to be conducted. The Company is
duly qualified and is authorized to do business and is in good standing as a
foreign corporation in all jurisdictions in which the nature of its activities
and of its properties (both owned and leased) makes such qualification
necessary, except for those jurisdictions in which failure to do so would not
have a material adverse effect on the Company or its business.

                  3.2 SUBSIDIARIES. The Company owns no equity securities of any
other corporation, limited partnership or similar entity. The Company is not a
participant in any joint venture, partnership or similar arrangement.

                  3.3 CAPITALIZATION. The authorized capital stock of the
Company, immediately prior to the Closing, will consist of ten million two
hundred twenty-five thousand (10,225,000) shares of Common Stock, par value
$.001 per share, three million one hundred twenty thousand (3,120,000) shares of
which are issued and outstanding and one million eight hundred forty-six
thousand six hundred sixty-six (1,846,666) shares of which are reserved for
future issuance to employees pursuant to the Company's Stock Option Plan and
five million two hundred twenty-five thousand (5,225,000) shares of Series A
Stock, par value $.001 per share, none of which are issued and outstanding. All
issued and outstanding shares of the Company's Common Stock (a) have been duly
authorized and validly issued, (b) are fully paid and nonassessable, and (c)
were issued in compliance with all applicable state and federal laws concerning
the issuance of securities. The rights, preferences, privileges and restrictions
of the Shares are as stated in the Restated Certificate. Each series of
Preferred Stock is convertible into Common Stock initially on a one-for-one
basis. The Conversion Shares have been duly and validly reserved for issuance.
Other than the warrant to be issued pursuant to the Agreement with Concept
Ventures, dated February 19, 1998, to purchase up to an aggregate of 33,334
shares of Common Stock of the Company and the one million eight hundred
forty-six thousand six hundred sixty-six (1,846,666) shares reserved for
issuance under the Company's Stock Option Plan, and except as may be granted
pursuant to the Related Agreements, there are no outstanding options, warrants,
rights (including conversion or preemptive rights and rights of first refusal),
proxy or stockholder agreements, or agreements of any kind for the purchase or
acquisition from the Company of any of its securities. When issued in compliance
with the provisions of this Agreement and the Restated Certificate, the Shares
and the Conversion Shares will be validly issued, fully paid and nonassessable,
and will be free of any liens or encumbrances; provided, however, that the
Shares and the Conversion Shares may be subject to restrictions on transfer
under state and/or federal securities laws as set forth herein or as otherwise
required by such laws at the time a transfer is proposed. No stock plan, stock
purchase, stock option or other agreement or understanding between the Company
and any holder of any equity securities or rights to purchase equity securities
provides for acceleration or other changes in the vesting provisions or other
terms of such agreement or understanding as the result of any merger,
consolidated sale of stock or assets, change in control or other similar
transaction by the Company.

                  3.4 AUTHORIZATION; BINDING OBLIGATIONS. All corporate action
on the part of the Company, its officers, directors and stockholders necessary
for the authorization of this Agreement and the Related Agreements, the
performance of all obligations of the Company hereunder and thereunder at the
Closing and the authorization, sale, issuance and delivery of the Shares
pursuant hereto and the Conversion Shares pursuant to the Restated Certificate
has been taken or will be taken prior to the Closing. The Agreement and the
Related Agreements, when executed and delivered, will be valid and binding
obligations of the Company enforceable in accordance with their terms, except
(a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium
or other laws of general application affecting enforcement of creditors' rights;
(b) general principles of equity that restrict the availability of equitable
remedies; and (c) to the extent that the enforceability of the indemnification
provisions in Section 2.9 of the Investors' Rights Agreement may be limited by
applicable laws. The sale of the Shares and the subsequent conversion of the
Shares into Conversion Shares are not and will not be subject to any preemptive
rights or rights of first refusal that have not been properly waived or complied
with.

                  3.5 BALANCE SHEET. The Company has delivered to each Purchaser

                           (j)      Any debt, obligation or liability incurred,
assumed or guaranteed by the Company, except those for immaterial amounts and
for current liabilities incurred in the ordinary course of business;

                           (k)      Any sale, assignment or transfer of any

                           (l)      Any change in any material agreement to

adversely affects the business, assets, liabilities, financial condition,
operations or prospects of the Company; or

                           (m)      Any other event or condition of any
character that, either individually or cumulatively, has materially and
adversely affected the business, assets, liabilities, financial condition,
operations or prospects of the Company. For purposes of this subsection (m), a
material and adverse effect shall only be deemed to occur if its monetary impact

<PAGE>   10

title to its leasehold estates, in each case subject to no mortgage, pledge,
lien, lease, encumbrance or charge, other than (a) those resulting from taxes
which have not yet become delinquent, (b) minor liens and encumbrances which do
not materially detract from the value of the property subject thereto or
materially impair the operations of the Company, (c) those that have otherwise
arisen in the ordinary course of business and (d) those attributable to purchase
money security interests or equipment leases and similar financings disclosed on
the Schedule of Exceptions. All facilities, equipment, fixtures and other
properties owned, leased or used by the Company are in good operating condition
and repair and are reasonably fit and usable for the purposes for which they are
being used. The Company is in compliance with all material terms of each lease
to which it is a party or is otherwise bound.

                  3.11 PATENTS AND TRADEMARKS. Except as set forth in Schedule
3.11, the Company owns or possesses sufficient legal rights to all trademarks,
service marks, trade names, copyrights, trade secrets and licenses, and, to the
best knowledge of the Company, to all patents, information and other proprietary
rights and processes (collectively, the"Intellectual Property") necessary for
its business as now conducted and as presently proposed to be conducted, without
any known infringement of the rights of others. There are no outstanding
options, licenses or agreements of any kind relating to the foregoing, nor is
the Company bound by or a party to any options, licenses or agreements of any
kind with respect to the patents, trademarks, service marks, trade names,
copyrights, trade secrets, licenses, information and other proprietary rights
and processes of any other person or entity other than such licenses or
agreements arising from the purchase of "off the shelf" or standard products.
The Company has not received any communications alleging that the Company has
violated or, by conducting its business as presently proposed in the Business
Plan (as defined below), would violate any of the patents, trademarks, service
marks, trade names, copyrights or trade secrets or other proprietary rights of
any other person or entity. The Company has no knowledge that it is infringing
upon the Intellectual Property rights of any third party. The Company is not
aware that any of its employees is obligated under any contract (including
licenses, covenants or commitments of any nature) or other agreement, or subject
to any judgment, decree or order of any court or administrative agency, that
would interfere with their duties to the Company or that would conflict with the
Company's business as presently proposed to be conducted in the Business Plan.
Neither the execution nor delivery of this Agreement, nor the carrying on of the
Company's business by the employees of the Company, nor the conduct of the

operations or prospects of the Company. The execution, delivery, and performance
of and compliance with this Agreement and the Related Agreements, and the
issuance and sale of the Shares pursuant hereto and of the Conversion Shares
pursuant to the Restated Certificate, will not, with or without the passage of
time or giving of notice, result in any such material violation, or be in
conflict with or constitute a default under any such term, or result in the
creation of any mortgage, pledge, lien, encumbrance or charge upon any of the
properties or assets of the Company or the suspension, revocation, impairment,
forfeiture or nonrenewal of any permit license, authorization or approval
applicable to the Company, its business or operations or any of its assets or
properties.

                  3.13 LITIGATION. Except as set forth in Schedule 3.13, there

contemplated hereby or thereby, or which might result, either individually or in
the aggregate, in any material adverse change in the assets, condition, affairs
or prospects of the Company, financially or otherwise, or any change in the
current equity ownership of the Company, nor is the Company aware that there is
any basis for the foregoing. The foregoing includes, without limitation, actions
pending or threatened in writing (or any basis therefor known to the Company)
involving the prior employment of any of the Company's employees, their use in
connection with the Company's business of any information or techniques
allegedly proprietary to any of their former employers, or their obligations

Company is not a party to or bound by any currently effective employment
contract, deferred compensation arrangement, bonus plan, incentive plan, profit
sharing plan, retirement agreement or other employee compensation plan or

consultant with whom the Company has contracted, is in violation of any term of
any proprietary information agreement or any other agreement relating to the
right of any such individual to be employed by, or to contract with, the Company
because of the nature of the business to be conducted by the Company; and to the
Company's knowledge the continued employment by the Company of its present
employees, and the performance of the Company's contracts with its independent
contractors, will not result in any such violation. The Company has not received
any notice alleging that any such violation has occurred. No employee of the
Company has been granted the right to continued employment by the Company or to
any material compensation following termination of employment with the Company.
The Company

                                        8

and has not granted any rights, to register (as defined in Section 1.1 of the
Investors' Rights Agreement) any of the Company's presently outstanding
securities or any of its securities that may hereafter be issued.

                  3.19 COMPLIANCE WITH LAWS; PERMITS. To its knowledge, the
Company is not in violation of any applicable statute, rule, regulation, order
or restriction of any domestic or foreign government or any instrumentality or

Company has all franchises, permits, licenses and any similar authority
necessary for the conduct of its business as now being conducted by it, the lack
of which could materially and adversely affect the business, properties,
prospects or financial condition of the Company and believes it can obtain,
without undue burden or expense, any similar authority for the conduct of its
business as planned to be conducted.

                  3.20 OFFERING VALID. Assuming the accuracy of the

                  3.21 FULL DISCLOSURE. This Agreement, the Exhibits hereto, the
Related Agreements and all other documents delivered by the Company to
Purchasers or their attorneys or agents in connection herewith or therewith or
with the transactions contemplated hereby or thereby, do not contain any untrue
statement of a material fact nor, to the Company's knowledge, omit to state a
material fact necessary in order to make the statements contained herein or
therein not misleading. Notwithstanding the foregoing, the Business Plan, dated
April 3, 1998 as supplemented by the version 9 financial information dated July
8, 1998 (the "Business Plan") provided to each of the Purchasers was prepared by
the management of the Company in a good faith effort to describe the Company's
presently proposed business and products and the markets therefore. The
assumptions applied in preparing the Business Plan appeared reasonable to
management as of the date thereof and as of the date hereof; however, there is
no assurance that these assumptions will prove to be valid or that the
objectives set forth in the Business Plan will be achieved. To the Company's
knowledge, there are no facts which (individually or in the aggregate)
materially adversely affect the business, assets, liabilities, financial
condition, prospects or operations of the Company that have not been set forth
in the Agreement, the Exhibits hereto, the Related Agreements or in other
documents delivered to Purchasers or their attorneys or agents in connection
herewith.

                  3.22 QUALIFIED SMALL BUSINESS. The Company represents and
warrants to the Purchasers that, to the best of its knowledge, the Company is a
"qualified small business" within the meaning of Section 1202(d) of the Internal
Revenue Code of 1986, as amended (the "Code") as of the date hereof and the
Shares should qualify as "qualified small business stock" as defined in Section
1202(c) of the Code as of the date hereof. The Company further represents and
warrants that, as of the date hereof, it meets the "active business requirement"
of Section 1202(e) of the Code, and it has made no "significant redemptions"
within the meaning of Section 1202(c)(3)(B) of the Code. The Company will use
reasonable efforts to comply with the reporting and recordkeeping requirements
of Section 1202 of the Code, any regulations promulgated thereunder and any
similar state laws and regulations, and agrees not to repurchase any stock of
the Company if such repurchase would constitute a "significant redemption"
within the meaning of Section 1202(c)(3)(B) of the Code with respect to the
Sharers.

                  3.23 MINUTE BOOKS. The minute books of the Company

delivery of this Agreement and the Related Agreements have been or will be
effectively taken prior to the Closing. Upon their execution and delivery, this
Agreement and the Related Agreements will be valid and binding obligations of
Purchaser, enforceable in accordance with their terms, except (a) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other laws of
general application affecting enforcement of creditors' rights, (b) general
principles of equity that restrict the availability of equitable remedies, and
(c) to the extent that the enforceability of the indemnification provisions of

transactions of securities in companies similar to the Company so that it is

risk of this investment indefinitely unless the Shares (or the Conversion
Shares) are registered pursuant to the Securities Act, or an exemption from
registration is available. Purchaser understands that the Company has no present
intention of registering the Shares, the Conversion Shares or any shares of its
Common Stock. Purchaser also understands that there is no assurance that any
exemption from registration under the Securities Act will be available and that,

portion of the Shares or the Conversion Shares under the circumstances, in the
amounts or at the times Purchaser might propose.

                           (b)      ACQUISITION FOR OWN ACCOUNT. Purchaser is

Company's operations and facilities. Purchaser has also had the opportunity to
ask questions of and receive answers from, the Company and its management
regarding the terms and conditions of this investment.

that the Shares, and, if issued, the Conversion Shares must be held indefinitely
unless they are subsequently registered under the Securities Act or an exemption
from such registration is available. Purchaser has been advised or is aware of
the provisions of Rule 144 promulgated under the Securities Act as in effect
from time to time, which permits limited resale of shares purchased in a private
placement subject to the satisfaction of certain conditions, including, among
other things: the availability of certain current public information about the
Company, the resale occurring following the required holding period under Rule
144 and the number of shares being sold during any three-month period not
