         Each Reporting Person expects to evaluate on an ongoing basis the
Issuer's financial condition, business operations and prospects, market price of
the Common Stock, conditions in securities markets generally, general economic
and industry conditions and other factors. Accordingly, each Reporting Person
reserves the right to change its plans and intentions at any time, as it deems
appropriate. In particular, each Reporting Person may, at any time and from time
to time: acquire additional Common Stock or securities convertible or
exchangeable for Common Stock; dispose of shares of Common Stock; and/or enter
into privately negotiated derivative transactions with institutional
counterparties to hedge the market risk of some or all of its positions in the
Common Stock. Any such transactions may be effected at any time and from time to
time subject to any applicable limitations of the Securities Act of 1933, as
amended (the "Securities Act"), and the contractual restrictions described in

Item 6. Contracts, Arrangements, Understandings or
Relationships with Respect to Securities of the Issuer.
- -------------------------------------------------------------

         Pursuant to a Standstill and Voting Agreement dated as of March 12,
1996, between the Issuer and SBH, which is filed as an exhibit to this Statement
and incorporated by reference into this Item 6, SBH is prohibited from
purchasing additional shares of the Issuer's capital stock if such purchase
would result in SBH owning more than 35% of the Issuer's capital stock (assuming
the exercise of all outstanding options and warrants to purchase capital stock).
The restrictions terminate on March 12, 2001 or earlier in the event that the
Issuer's founders, David Filo and Jerry Yang, own beneficially less than
2,500,000 shares of the Issuer's Common Stock, in the aggregate. Also, SBH's
maximum permitted percentage ownership increases to 49.5% of the Issuer's
capital stock (excluding options and warrant to purchase capital stock) in the
event that Messrs. Filo and Yang beneficially own in the aggregate less than
4,000,000 shares of Common Stock. The agreements also prohibit SBH from
disposing of shares representing more than 5% of the Issuer's capital stock
without approval of the Issuer's Board of Directors (other than in public market
sales under Rule 144 or pursuant to a registration statement filed by the
Issuer).

         The Purchasers (including, as defined therein, SBH) and the Issuer
entered into a Second Amended and Restated Investor Rights Agreement, dated as
of March 12, 1996 (the "Investor Rights Agreement"), which is filed as an
exhibit to this Statement and incorporated by reference into this Item 6. The
Investor Rights Agreement provides SBH with the right to require the Issuer to
register any or all of the Common Stock held by it in a public offering pursuant
to the Securities Act. Such registration is subject to the right of the Issuer
to delay any exercise by SBH of this right for a period of up to 180 days if, in
the Issuer's judgment, the Issuer or any financing, acquisition, corporate
reorganization or other material transaction by the Issuer or any of its
subsidiaries then being conducted or about to be conducted would be adversely
affected. Pursuant to the Investor Rights Agreement, SBH also has the right to
"piggyback" or include its Common Stock in any registration of Common Stock made
by the Issuer.

         The Amendment to Second Amended and Restated Investor Rights Agreement
dated July 7, 1998 among the Issuer and the Purchasers (including, as defined
therein, SBH), which is filed as an exhibit to this Statement and incorporated
by reference into this Item 6, specifically included in the rights granted to
SBH under the Investor Rights Agreement the shares purchased pursuant to the
Stock Purchase Agreement dated July 7, 1998 between the Issuer and SBH which was
filed as an exhibit to the Original Schedule 13D and is incorporated by
reference into this Item 6.

         In a Subscription Agreement, dated December 31, 1998, between SBH and
SB America, which is filed as an exhibit to this Statement and incorporated by
reference into this Item 6, SBH subscribed to 100 shares of Common Stock of SB
America for a purchase price of $10 per share. As an additional contribution to
capital, SBH assigned and transferred to SB America all of its right, title and
interest in, inter alia, the Common Stock, free and clear of all liens,
encumbrances, equities or claims.

         For a  description  of the  Agreement  and Plan of  Merger  dated as of
October 9, 1998, among the Issuer and Yoyodyne, see Item 3 of this Statement.

         The summary descriptions contained in this Statement of certain
agreements and documents are qualified in their entirety by reference to the
complete texts of such agreements and documents filed as Exhibits hereto and
incorporated herein by reference.

                      AMENDMENT NO. 1 TO SECOND AMENDED AND
                       RESTATED INVESTOR RIGHTS AGREEMENT


         This Amendment No. 1 to Second Amended and Restated Investor Rights
Agreement (the "Amendment") dated as of March 27, 1996, is entered into by and
among Yahoo! Inc., a California corporation (the "Company"), and the other
parties hereto, with respect to the Second Amended and Restated Investor Rights
Agreement dated as of March 12, 1996, by and among the Company and the other
parties thereto (the "Agreement").

                                    RECITALS

         WHEREAS, the Company is issuing a Warrant (the "Visa Warrant") to Visa
International Service Association, a Delaware corporation ("Visa"), to acquire
350,000 shares of the Company's Common Stock (the shares of Common Stock
acquirable under the Visa Warrant are hereafter referred to as the "Visa Warrant
Shares");

         WHEREAS, under the terms of the Visa Warrant, the Company is required
to grant to Visa with respect to the Warrant Shares the same registration rights
as granted, in Section 2.3 of the Agreement, to the Series A, Series B and
Series C Investors, as defined in the Agreement, and the Company wishes to make
such grant by amending the Agreement to make Visa a party thereto;

         WHEREAS, under Section 1.1 of the Agreement the Company may amend the
Agreement only with the written consent of the Company and the holders of a
majority of the outstanding Registrable Securities, as defined in the Agreement
("Outstanding Series A, Series B and Series C Shares"); and

         WHEREAS, to grant Visa the rights required under the Visa Warrant, the
parties hereto desire to enter into this Amendment in accordance with Section
1.1 of the Agreement.

         NOW, THEREFORE, IT IS AGREED THAT:

         1. Definitions. All capitalized terms used herein without definition
shall have the meanings ascribed to them in the Agreement.

         2. Amendment.

               (a) Section 2.1(b) of the Agreement is hereby amended as follows:

               (b) The terms "REGISTRABLE SECURITIES" means:

                   (i) The Shares of Common Stock issuable or issued upon
conversion of the Series A Shares, Series B Shares and Series C Shares (the
Series A Shares, the Series B Shares and the Series C Shares sometimes
collectively referred to as the "STOCK");






                   (ii) Any other shares of Common Stock of the Company issued
as (or issuable upon the conversion or exercise of any warrant, right or other
security which is issued as) a dividend or other distribution with respect to,
or in exchange for or in replacement of, the Stock, excluding in all cases,
however, any Registrable Securities sold by a person in a transaction in which
his or her rights under this Agreement are not assigned; and

                   (iii) For purposes of Section 2.3 of the Agreement only
(relating to certain "piggyback registration rights"), the Visa Warrant Shares,
and any other shares of Common Stock of the Company issued as (or issuable upon
the conversion or exercise of any warrant, right or other security which is
issued as) a dividend or other distribution with respect to, or in exchange for
or in replacement of, the Visa Warrant Shares, excluding in all cases, however,
any Registrable Securities sold by a person in a transaction in which his or her
rights under this Agreement are not assigned.

provided, however, that Common Stock or other securities shall only be treated
as Registrable Securities if and so long as they have not been (A) sold to or
through a broker or dealer or underwriter in a public distribution or a public
securities transaction, or (B) sold in a transaction exempt from the
registration and prospectus delivery requirements of the Securities Act under
Section 4(1) thereof so that all transfer restrictions, and restrictive legends
with respect thereto, if any, are removed upon the consummation of such sale.

         3. Visa. Upon the effectiveness of this Amendment, as provided in
Section 4 hereof, Visa agrees to be bound by all of the terms and conditions of
the Agreement.

         4. Effect of Amendment. Except as amended as set forth above, the
Agreement shall continue in full force and effect.

         5. Counterparts. This Amendment may be signed in one or more
counterparts, each of which shall be deemed an original and all of which, taken
together, shall be deemed one and the same document.

                          AGREEMENT AND PLAN OF MERGER

         THIS AGREEMENT AND PLAN OF MERGER dated as of October 9, 1998 (this
"AGREEMENT"), is entered into by and among Yahoo! Inc., a California corporation
("ACQUIROR"), YO Acquisition Corporation, a Delaware corporation and a
wholly-owned subsidiary of Acquiror ("SUB"), and Yoyodyne Entertainment, Inc., a
Delaware corporation ("TARGET").

                                                     RECITALS:

      A.  The Boards of Directors of Acquiror, Sub and Target deem it advisable
and in the best interests of each corporation and their respective stockholders
that Acquiror and Target combine in order to advance the long-term business
interests of Acquiror and Target;

      B.  The combination of Acquiror and Target shall be effected by the terms
of this Agreement through a transaction in which Sub will merge with and into
Target, Target will become a wholly-owned subsidiary of Acquiror and the
stockholders of Target will become shareholders of Acquiror (the "MERGER");

      C.  For Federal income tax purposes, it is intended that the Merger shall
qualify as a reorganization within the meaning of Section 368(a) of the Internal
Revenue Code of 1986, as amended (the "CODE");

      D.  For accounting purposes, it is intended that the Merger shall be
accounted for as a pooling of interests transaction;

      E.  As a condition and inducement to Acquiror's willingness to enter into
this Agreement, certain Target stockholders holding no less than 95% of the
issued and outstanding voting stock of Target, have, concurrently with the
execution of this Agreement, executed and delivered Voting Agreements in the
form attached hereto as Exhibit A (the "VOTING AGREEMENTS"), pursuant to which
such stockholders have, among other things, agreed to vote their shares of
Target capital stock in favor of the Merger and to grant Acquiror irrevocable
proxies to vote such shares;

      F.  As a further condition and inducement to Acquiror's willingness to
enter into this Agreement, certain employees of Target who are also stockholders
of Target have, concurrently with the execution of this Agreement executed and
delivered Noncompetition Agreements in the form attached hereto as Exhibit B
(the "NONCOMPETITION AGREEMENTS"), which agreements shall only become effective
at the Effective Time (as defined in Section 1.1 below).

      G.  As a further condition and inducement to Acquiror's willingness to
enter into this Agreement, certain stockholders of Target have executed and
delivered to Acquiror Stockholders Agreements in the form attached hereto as

      Section 1.3   Effects of the Merger.

      (a) At the Effective Time (i) the separate existence of Sub shall cease

                                   ARTICLE II

                            CONVERSION OF SECURITIES

      Section 2.1  Conversion of Capital Stock. At the Effective Time, by virtue

          (b)  Cancellation of Acquiror-Owned and Target-Owned Stock. Any shares

Sub, Target or any other direct or indirect wholly-owned Subsidiary (as defined
below) of Acquiror or Target shall be canceled and retired and shall cease to
exist and no stock of Acquiror or other consideration shall be delivered in
exchange. As used in this Agreement, the word "SUBSIDIARY" means, with respect
to any other party, any corporation or other organization, whether incorporated

          (c)  Exchange Ratio.

               (i)  Subject to Sections 2.2 and 2.4, each issued and outstanding
share of Target Common Stock and Target Preferred Stock (other than shares to 
be canceled in accordance with Section 2.1(b) and any Dissenting Shares as 
defined in and to the extent provided in Section 2.3) shall, by virtue of the
Merger and without any action on the part of the holder thereof, be converted
into the right to receive a fraction of a fully paid and nonassessable share of
Acquiror Common Stock (as defined in Section 4.2) equal to the "COMMON EXCHANGE
RATIO" or the "PREFERRED EXCHANGE RATIO", as the case may be, as defined in and
determined in accordance with the provisions of this Section 2.1(c). All such
shares of Target Common Stock and Target Preferred Stock, when so converted,
shall no longer be outstanding and shall automatically be canceled and retired
and shall cease to exist, and each holder of a certificate representing any
such shares shall cease to have any rights with respect thereto, except the
right to receive the shares of Acquiror Common Stock and any cash in lieu of
fractional shares of

Acquiror Common Stock to be issued or paid in consideration therefor upon the
surrender of such certificate in accordance with Section 2.4, without interest.

               (ii) The "TOTAL CONSIDERATION SHARES" shall be equal to 280,664
shares of Acquiror Common Stock. The "PREFERRED EXCHANGE RATIO" shall be equal
to (i) the number of the Total Consideration Shares required to be distributed
to the holders of Target Preferred Stock, pursuant to Target's Certificate of
Incorporation, divided by (ii) the number of shares of Target Preferred Stock
outstanding as of the Effective Time. The "COMMON EXCHANGE RATIO" shall be equal
to (i) the number of the Total Consideration Shares required to be distributed
to the holders of Target Common Stock (assuming prior exercise for cash of all
Target Options and Target Warrants), pursuant to Target's Certificate of
Incorporation, divided by (ii) the number of shares of Target Common Stock
outstanding or subject to issuance upon exercise of Target Options and Target
Warrants as of the Effective Time. The Preferred Exchange Ratio and the Common
Exchange Ratio are referred to collectively as the "EXCHANGE RATIOS". In no
event will the total number of shares of Acquiror Common Stock issuable by
Acquiror pursuant to the Merger (including shares of Acquiror Common Stock
issuable upon exercise of Target Options or Target Warrants assumed by Target in
the Merger) exceed the Total Consideration Shares. The allocation of the Total
Consideration Shares among each holder of Target capital stock, warrants and
options is set forth in the Disclosure Schedule.

              (iii) If, on or after the date of this Agreement and prior to the
Effective Time, the outstanding shares of Acquiror Common Stock or Target
Preferred Stock shall have been changed into a different number of shares or a
different class by reason of any reclassification, split-up, stock dividend or
stock combination, then the Exchange Ratios shall be correspondingly adjusted.
The Exchange Ratios shall not change as a result of fluctuations in the market
price of Acquiror Common Stock between the date of this Agreement and the
Effective Time.

          (d)  Target Stock Options and Warrants. At the Effective Time, all
then outstanding options, whether vested or unvested ("TARGET OPTIONS") to 
purchase Target Common Stock issued under Target's 1996 Stock Option Plan (the
"TARGET OPTION PLAN") and all outstanding warrants to purchase Target Common
Stock ("TARGET WARRANTS") that by their terms survive the Closing will be
assumed by Acquiror in accordance with Section 6.5. All of the Target Options
and all of the Target Warrants issued and outstanding as of the date of this
Agreement are listed on Schedule 2.1(d) attached hereto. An updated Schedule
2.1(d) of Target Options and Target Warrants shall be delivered by Target to
Acquiror on the Closing Date.

          (e)  Restricted Shares. Any shares of Target Common Stock which are
subject to repurchase by Target in the event the holder thereof ceases to be 
employed by Target ("TARGET RESTRICTED SHARES") shall be converted into 
Acquiror Common Stock on the same basis as provided in subsection (c) above and
shall be registered in such holder's name, but shall be held by Target or
Acquiror pursuant to the existing agreements in effect on the date of this
Agreement. Holders of the Target Restricted Shares are identified on Schedule
2.1(e) together with the vesting schedules associated with such shares.

                                      - 4 -




      Section 2.2   Escrow Agreement. At the Effective Time or such later time
as determined in accordance with Section 2.3(b), Acquiror will, on behalf of the
holders of Target Common Stock, Target Preferred Stock, Target Options and
Target Warrants, deposit in escrow certificates representing 23,528 shares of
Acquiror Common Stock. Such shares shall be held in escrow on behalf of the
persons who are the holders of Target Common Stock or Target Preferred Stock in
the Merger immediately prior to the Effective Time (the "FORMER TARGET
STOCKHOLDERS"), in accordance with the portion of Total Consideration Shares
allocable to each such Former Target Stockholder based upon the Exchange Ratios
("PRO RATA PORTION"). Such shares (collectively, the "ESCROW SHARES") shall be
held and applied pursuant to the provisions of an escrow agreement (the "ESCROW
AGREEMENT") to be executed pursuant to Section 7.6.

      Section 2.3   Dissenting Shares.

          (a)  Notwithstanding any provision of this Agreement to the contrary,
any shares of Target Common Stock or Target Preferred Stock held by a holder
who has exercised such holder's appraisal rights in accordance with Section 262
of Delaware Law, and who, as of the Effective Time, has not effectively 
withdrawn or lost such appraisal rights ("DISSENTING SHARES"), shall not be
converted into or represent a right to receive Acquiror Common Stock pursuant
to Section 2.1, but the holder of the Dissenting Shares shall only be entitled
to such rights as are granted by Section 262 of Delaware Law.

          (b) Notwithstanding the provisions of Section 2.3(a), if any holder
of shares of Target Common Stock or Target Preferred Stock who demands his
appraisal rights with respect to such shares under Section 2.1 shall effectively
withdraw or lose (through failure to perfect or otherwise) his rights to receive
payment for the fair market value of such shares under Delaware Law, then, as of
the later of the Effective Time or the occurrence of such event, such holder's
shares shall automatically be converted into and represent only the right to
receive Acquiror Common Stock and payment for fractional shares as provided in
Section 2.1(c), without interest, upon surrender of the certificate or
certificates representing such shares; provided that if such holder effectively
withdraws or loses his right to receive payment for the fair market value of
such shares after the Effective Time, then, at such time Acquiror will deposit
in escrow certificates representing such holder's Pro Rata Portion of the Escrow
Shares.

          (c)  Target shall give Acquiror (i) prompt notice of any written
demands for payment with respect to any shares of capital stock of Target
pursuant to Section 262 of Delaware Law, withdrawals of such demands, and any
other instruments served pursuant to Delaware Law and received by the Target
and (ii) the opportunity to participate in all negotiations and proceedings
with respect to demands for appraisal rights under Delaware Law. Target shall
not, except with the prior written consent of Acquiror, voluntarily make any
payment with respect to any demands for appraisal rights with respect to Target
Common Stock or Target Preferred Stock or offer to settle or settle any such
demands.

      Section 2.4   Exchange of Certificates.

          (a)  From and after the Effective Time, each holder of an outstanding
certificate or certificates ("CERTIFICATES") which represented shares of Target
Common Stock or

                                      - 5 -




Target Preferred Stock immediately prior to the Effective Time shall have the
right to surrender each Certificate to Acquiror (or at Acquiror's option, an
exchange agent to be appointed by Acquiror), and receive promptly in exchange
for all Certificates held by such holder a certificate representing the number
of whole shares of Acquiror Common Stock (other than the Escrow Shares) into
which the Target Common Stock or Target Preferred Stock evidenced by the
Certificates so surrendered shall have been converted pursuant to the provisions
of Article II of this Agreement. The surrender of Certificates shall be
accompanied by duly completed and executed Letters of Transmittal in such form
as may be reasonably specified by Acquiror. Until surrendered, each outstanding
Certificate which prior to the Effective Time represented shares of Target
Common Stock or Target Preferred Stock shall be deemed for all corporate
purposes to evidence ownership of the number of whole shares of Acquiror Common
Stock into which the shares of Target Common Stock have been converted but
shall, subject to applicable appraisal rights under Delaware Law and Section 
2.3, have no other rights. Subject to applicable appraisal rights under Delaware
Law and Section 2.3, from and after the Effective Time, the holders of shares of
Target Common Stock and Target Preferred Stock shall cease to have any rights in
respect of such shares and their rights shall be solely in respect of the
Acquiror Common Stock into which such shares of Target Common Stock or Target
Preferred Stock have been converted. From and after the Effective Time, there
shall be no further registration of transfers on the records of Target of shares
of Target Common Stock and Target Preferred Stock outstanding immediately prior
to the Effective Time.

          (b)  If any shares of Acquiror Common Stock are to be issued in the
name of a person other than the person in whose name the Certificate(s) 
surrendered in exchange therefor is registered, it shall be a condition to the
issuance of such shares that (i) the Certificate(s) so surrendered shall be
transferable, and shall be properly assigned, endorsed or accompanied by
appropriate stock powers, (ii) such transfer shall otherwise be proper and
(iii) the person requesting such transfer shall pay Acquiror, or its exchange
agent, any transfer or other taxes payable by reason of the foregoing or
establish to the satisfaction of Acquiror that such taxes have been paid or are
not required to be paid. Notwithstanding the foregoing, neither Acquiror nor
Target shall be liable to a holder of shares of Target Common Stock or Target
Preferred Stock for shares of Acquiror Common Stock issuable to such holder
pursuant to the provisions of Article II of this Agreement that are delivered
to a public official pursuant to applicable abandoned property, escheat or
similar laws.

          (c)  In the event any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed, Acquiror shall issue in
exchange for such lost, stolen or destroyed Certificate the shares of Acquiror
Common Stock issuable in exchange therefor pursuant to the provisions of Article
II of the Agreement. The Board of Directors of Acquiror may in its discretion
and as a condition precedent to the issuance thereof, require the owner of such
lost, stolen or destroyed Certificate to provide to Acquiror an indemnity
agreement against any claim that may be made against Acquiror with respect to
the Certificate alleged to have been lost, stolen or destroyed.

      Section 2.5   Distributions with Respect to Unexchanged Shares.  No
dividends or other distributions declared or made after the Effective Time
with respect to Acquiror Common Stock

                                      - 6 -




with a record date after the Effective Time shall be paid to the holder of any
unsurrendered Certificate with respect to the shares of Acquiror Common Stock
represented thereby and no cash payment in lieu of fractional shares shall be
paid to any such holder pursuant to Section 2.6 below until the holder of record
of such Certificate shall surrender such Certificate. Subject to the effect of
applicable laws, following surrender of any such Certificate, there shall be
paid to the record holder of the certificates representing whole shares of
Acquiror Common Stock issued in exchange therefor, without interest, (i) at the
time of such surrender, the amount of any cash payable in lieu of a fractional
share of Acquiror Common Stock to which such holder is entitled pursuant to
Section 2.6 below and the amount of any dividends or other distributions with a
record date after the Effective Time previously paid with respect to such whole
shares of Acquiror Common Stock, and (ii) at the appropriate payment date, the
amount of dividends or other distributions with a record date after the
Effective Time but prior to surrender and a payment date subsequent to surrender
payable with respect to such whole shares of Acquiror Common Stock.

      Section 2.6   No Fractional Shares. No certificate or scrip representing
fractional shares of Acquiror Common Stock shall be issued upon the surrender
for exchange of Certificates, and such fractional share interests will not
entitle the owner thereof to vote or to any rights of a shareholder of Acquiror.
Notwithstanding any other provision of this Agreement, each holder of shares of
Target Common Stock or Target Preferred Stock exchanged pursuant to the Merger
who would otherwise have been entitled to receive a fraction of a share of
Acquiror Common Stock (after taking into account all Certificates delivered by
such holder) shall receive, in lieu thereof, cash (without interest) in an
amount equal to such fractional part of a share of Acquiror Common Stock
multiplied by $119.36.

      Section 2.7   Tax and Accounting Consequences.

          (a)  It is intended by the parties hereto that the Merger shall
constitute a "reorganization" within the meaning of Section 368 of the Code.
The parties hereto adopt this Agreement as a "plan of reorganization" within
the meaning of Sections 1.368-2(g) and 1.368- 3(a) of the United States Income
Tax Regulations.

          (b)  It is intended by the parties hereto that the Merger shall
qualify for accounting treatment as a pooling of interests.

          (b)  Except as set forth in this Section 3.2, there are no equity

of the Target Option Plan and pursuant to the standard forms of option agreement
previously provided to Acquiror or its representatives. No option will by its
terms require an adjustment in connection with the Merger. Neither the
consummation of transactions contemplated by this Agreement or the other
Transaction Documents nor any action taken by Target in connection with such
transactions will result in (i) any acceleration of vesting in favor of any
optionee under any Target Option; (ii) any additional benefits for any optionee
under any Target Option; or (iii) the inability of Acquiror after the Effective
Time to exercise any right or benefit held by Target prior to the Effective Time

executed and delivered by Target, will constitute, assuming the due
authorization, execution and delivery by the other parties hereto and thereto,
the valid and binding obligation of Target, enforceable against Target in
accordance with their respective terms, except to the extent that enforceability
may be limited by applicable bankruptcy, reorganization, insolvency, moratorium
or other laws affecting the enforcement of creditors' rights generally and by
general principles of equity, regardless of whether such enforceability is
considered in a proceeding at law or in equity. For purposes of this Agreement,
"TRANSACTION DOCUMENTS" means all documents or agreements required to be
delivered by any party under this Agreement including the Certificate of Merger,
the Escrow Agreement, the Voting Agreements, the Stockholders Agreements and the
Noncompetition Agreements.

          (b)  The execution and delivery by Target of this Agreement and the
Transaction Documents to which it is or will become a party does not, and the

Transaction Documents to which it is or will become a party will not, (i)

of any other Transaction Document to which Target is or will become a party or
the consummation of the transactions contemplated by this Agreement or such
Transaction Document or the continuation of the business activities of Target

administrative agency or commission or other governmental authority or
instrumentality ("GOVERNMENTAL ENTITY"), except for (i) the filing of the
Certificate of Merger with the Delaware Secretary of State, (ii)

                                     - 10 -

      Section 3.4   Financial Statements; Absence of Undisclosed Liabilities.

          (a)  Target has delivered to Acquiror copies of Target's unaudited
balance sheet as of September 30, 1998 (the "MOST RECENT BALANCE SHEET") and
statements of operations, stockholders' equity and cash flow for the 9-month
period then-ended (together with the Most Recent Balance Sheet, the "TARGET
INTERIM FINANCIALS") and the audited balance sheets as of December 31, 1997,
and the related audited statements of operations, stockholders' equity and cash
flows for the fiscal year ended December 31, 1997, respectively (collectively,
the "TARGET FINANCIAL STATEMENTS").

          (b)  The Target Financial Statements are in accordance with the books
and records of Target and present fairly in all material respects the financial
position, results of operations and cash flows of Target as of their historical
dates and for the periods indicated. The Target Financial Statements have been
prepared in accordance with generally accepted accounting principles applied on
a basis consistent with prior periods. The reserves, if any, reflected on the
Target Financial Statements are adequate in light of the contingencies with
respect to which they were made.

          (c)  Target has no 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 in the Most Recent
Balance Sheet, except for those that may have been incurred after the date of
the Most Recent Balance Sheet or that would not reasonably be required, in
accordance with generally accepted accounting principles applied on a basis
consistent with prior periods, to be included in a balance sheet or the notes
thereto. All debts, liabilities, and obligations incurred after the date of the
Most Recent Balance Sheet were incurred in the ordinary course of business and
are not material both individually and in the aggregate to Target or its
business.

      Section 3.5   Tax Matters.

          (a)  For purposes of this Section 3.5 and other provisions of this
Agreement relating to Taxes, the following definitions shall apply:

               (i)  The term "TAXES" shall mean all taxes, however denominated,
including any interest, penalties or other additions to tax that may become
payable in respect thereof, (A) imposed by any federal, territorial, state,
local or foreign government or any agency or political subdivision of any such
government, which taxes shall include, without limiting the generality of the
foregoing, all income or profits taxes (including but not limited to, federal
income taxes and state income taxes), payroll and employee withholding taxes,
unemployment insurance, social security taxes, sales and use taxes, ad valorem
taxes, excise taxes, franchise taxes, gross receipts taxes, business license
taxes, occupation taxes, real and personal property

                                     - 11 -




taxes, stamp taxes, environmental taxes, ozone depleting chemicals taxes,
transfer taxes, workers' compensation, Pension Benefit Guaranty Corporation
premiums and other governmental charges, and other obligations of the same or
of a similar nature to any of the foregoing, which are required to be paid,
withheld or collected, (B) any liability for the payment of amounts referred to
in (A) as a result of being a member of any affiliated, consolidated, combined
or unitary group, or (C) any liability for amounts referred to in (A) or (B) as
a result of any obligations to indemnify another person.

               (ii) The term "RETURNS" shall mean all reports, estimates,
declarations of estimated tax, information statements and returns relating to,
or required to be filed in connection with, any Taxes, including information
returns or reports with respect to backup withholding and other payments to
third parties.

          (b)  All Returns required to be filed by or on behalf of Target have
been duly filed on a timely basis and such Returns are true, complete and
correct. All Taxes shown to be payable on such Returns or on subsequent
assessments with respect thereto, and all payments of estimated Taxes required
to be made by or on behalf of Target under Section 6655 of the Code or
comparable provisions of state, local or foreign law, have been paid in full on
a timely basis or have been accrued on the Most Recent Balance Sheet, and no
other Taxes are payable by Target with respect to items or periods covered by
such Returns (whether or not shown on or reportable on such Returns). Target
has withheld and paid over all Taxes required to have been withheld and paid
over, and complied with all information reporting and backup withholding
requirements, including maintenance of required records with respect thereto,
in connection with amounts paid or owing to any employee, creditor, independent
contractor, or other third party. There are no liens on any of the assets of
Target with respect to Taxes, other than liens for Taxes not yet due and payable
or for Taxes that Target is contesting in good faith through appropriate
proceedings and for which appropriate reserves have been established on the
Most Recent Balance Sheet.  Target has not at any time been (i) a member of an
affiliated group of corporations filing consolidated, combined or unitary
income or franchise tax returns, or (ii) a member of any partnership or joint
venture for a period for which the statue of limitations for any Tax potentially
applicable as a result of such membership has not expired.

          (c)  The amount of Target's liability for unpaid Taxes (whether actual
or contingent) for all periods through the date of the Most Recent Balance Sheet
does not, in the aggregate, exceed the amount of the current liability accruals
for Taxes reflected on the Most Recent Balance Sheet, and the Most Recent
Balance Sheet reflects proper accrual in accordance with generally accepted
accounting principles applied on a basis consistent with prior periods of all
liabilities for Taxes payable after the date of the Most Recent Balance Sheet
attributable to transactions and events occurring prior to such date. No
liability for Taxes has been incurred (or prior to Closing will be incurred)
since such date other than in the ordinary course of business.

          (d)  Acquiror has been furnished by Target with true and complete
copies of (i) relevant portions of income tax audit reports, statements of
deficiencies, closing or other agreements received by or on behalf of Target
relating to Taxes, and (ii) all federal and state income or franchise tax
Returns and state sales and use tax Returns for or including Target for all

                                     - 12 -




periods since the inception of Target. Target does not do business in or derive
income from any state other than states for which Returns have been duly filed
and furnished to Acquiror.

          (e)  The Returns of or including Target have never been audited by a
government or taxing authority, nor is any such audit in process, pending or,

informally). No deficiencies exist or have been asserted (either in writing or
verbally, formally or informally), and Target has not received notice (either in
writing or verbally, formally or informally) that it has not filed a Return or
paid Taxes required to be filed or paid. Target is neither a party to any action
or proceeding for assessment or collection of Taxes, nor has such event been

against Target or any of its assets. No waiver or extension of any statute of
limitations is in effect with respect to Taxes or Returns of Target. Target has
disclosed on its federal and state income and franchise tax Returns all
positions taken therein that could give rise to a substantial understatement

which it may have claimed, and the transactions contemplated by this Agreement
will not have any adverse effect on such compliance.

          (h) The Target Disclosure Schedule sets forth accurate and complete
information regarding Target's net operating losses for federal and each
applicable state tax purposes. Except as a result of the transactions

          (m)  agreed to take any action described in this Section 3.6 or
outside of its ordinary course of business or which would constitute a breach
of any of the representations contained in this Agreement.

      Section 3.7   Title and Related Matters. Target has good and valid title
to all its properties, interests in properties and assets, real and personal,
free and clear of all mortgages, liens, pledges, charges or encumbrances of any
kind or character, except the lien of current taxes not yet due and payable and

(ii) in good operating condition and repair, ordinary wear and tear excepted.
All personal property leases to which Target is a party are valid, binding,
enforceable against Target and in effect in accordance with their respective
terms. To the knowledge of Target, there is not under any of such leases any

time or both, would constitute a default. The Target Disclosure Schedule
contains a description of all items of personal property with an individual net
book value in excess of $1,000 and real property leased or owned by Target,
describing its interest in said property. True and correct copies of Target's
real property and personal property leases have been provided to Acquiror or
its representatives.

      Section 3.8   Proprietary Rights.

          (a)  Target owns all right, title and interest in and to, or otherwise
possesses legally enforceable rights, or is licensed to use, all patents,
copyrights, technology, software, software tools, know-how, processes, trade
secrets, trademarks, service marks, trade names, Internet domain names and other
proprietary rights used in the conduct of Target's business as conducted to the
date of this Agreement, including, without limitation, the technology,
information, databases, data lists, data compilations, and all proprietary
rights developed or discovered or used in connection with or contained in all
versions and implementations of Target's World Wide Web sites (including
www.yoyodyne.com and the other domain names listed in the Target Disclosure
Schedule) or any product which has been or is being distributed or sold by
Target or currently is under development by Target or has previously been under
development by Target (collectively, including such Web sites, the "TARGET
PRODUCTS"), free and clear of all liens, claims and encumbrances (including
without limitation licensing and distribution rights) (all of which are referred
to as "TARGET PROPRIETARY RIGHTS"). The Target Disclosure Schedule contains an
accurate and complete (i) description of all patents, trademarks (with separate
listings of registered and unregistered trademarks), trade names, Internet
domain names and registered copyrights in or related to the Target Products or
otherwise included in the Target Proprietary Rights and all applications and
registration statements therefor, including the jurisdictions in which each such
Target Proprietary Right has been issued or registered or in which any such
application of such issuance and registration has been filed, (ii) list of all
licenses and other agreements with third parties (the "THIRD PARTY LICENSES")
relating to any material patents, copyrights, trade secrets, software,
inventions, technology, know-how, processes or other proprietary rights that
Target is licensed or otherwise authorized by such third parties to use, market,
distribute or incorporate in Target Products (such patents, copyrights, trade
secrets,

                                     - 15 -




software, inventions, technology, know-how, processes or other proprietary
rights are collectively referred to as the "THIRD PARTY TECHNOLOGY") and (iii)
list of all licenses and other agreements with third parties relating to any
material information, compilations, data lists or databases that Target is
licensed or otherwise authorized by such third parties to use, market,
disseminate distribute or incorporate in Target Products. All of Target's
patents, copyrights, trademarks, trade names or Internet domain name
registrations related to or in the Target Products are valid and in full force
and effect; and consummation of the transactions contemplated by this Agreement
will not alter or impair any such rights. No claims have been asserted or
threatened against Target (and Target is not aware of any claims which are
likely to be asserted or threatened against Target or which have been asserted
or threatened against others relating to Target Proprietary Rights or Target
Products) by any person challenging Target's use, possession, manufacture, sale
or distribution of Target Products under any Target Proprietary Rights
(including, without limitation, the Third Party Technology) or challenging or
questioning the validity or effectiveness of any material license or agreement
relating thereto (including, without limitation, the Third Party Licenses) or
alleging a violation of any person's or entity's privacy, personal or
confidentiality rights. Target knows of no valid basis for any claim of the type
specified in the immediately preceding sentence which could in any material way
relate to or interfere with the continued enhancement and exploitation by Target
of any of the Target Products. None of the Target Products nor the use or
exploitation of any Target Proprietary Rights in Target's current business
infringes on the rights of or constitutes misappropriation of any proprietary
information or intangible property right of any third person or entity,
including without limitation any patent, trade secret, copyright, trademark or
trade name, and Target has not been sued or named in any suit, action or
proceeding which involves a claim of such infringement, misappropriation or
unfair competition.

          (b)  Except as set forth in the Target Disclosure Schedule, Target has
not granted any third party any right to reproduce, distribute, market or
exploit any of the Target Products or any adaptations, translations, or
derivative works based on the Target Products or any portion thereof. Except
with respect to the rights of third parties to the Third Party Technology, no
third party has any express right to reproduce, distribute, market or exploit
any works or materials of which any of the Target Products are a "derivative
work" as that term is defined in the United States Copyright Act, Title 17,
U.S.C. Section 101.

          (c)  All material designs, drawings, specifications, source code,
object code, scripts, documentation, flow charts, diagrams, data lists,
databases, compilations and information incorporating, embodying or reflecting
any of the Target Products at any stage of their development (the "TARGET
COMPONENTS") were written, developed and created solely and exclusively by
employees of Target without the assistance of any third party or entity or were
created by third parties who assigned ownership of their rights to Target by
means of valid and enforceable consultant confidentiality and invention
assignment agreements, copies of which have been delivered to Acquiror. Target
has at all times used commercially reasonable efforts customary in its industry
to treat the Target Proprietary Rights related to Target Products and Target
Components as containing trade secrets and has not disclosed or otherwise dealt
with such items in such a manner as intended or reasonably likely to cause the
loss of such trade secrets by release into the public domain.

                                     - 16 -




          (d)  To Target's knowledge, after due investigation, no employee,
contractor or consultant of Target is in violation in any material respect of
any term of any written employment contract, patent disclosure agreement or any
other written contract or agreement relating to the relationship of any such
employee, consultant or contractor with Target or, to Target's knowledge, any
other party because of the nature of the business conducted by Target or
proposed to be conducted by Target. The Target Disclosure Schedule lists all
employees, contractors and consultants who have participated in any way in the
development of the Target Products or the Target Proprietary Rights.

          (e)  Each person presently or previously employed by Target (including
independent contractors, if any) with access authorized by Target to
confidential information has executed a confidentiality and non-disclosure
agreement pursuant to the form of agreement previously provided to Acquiror or
its representatives.

          (f)  No product liability or warranty claims have been communicated
in writing to or threatened against Target.

          (g)  To Target's knowledge, there is no material unauthorized use,
disclosure, infringement or misappropriation of any Target Proprietary Rights,
or any Third Party Technology to the extent licensed by or through Target, by
any third party, including any employee or former employee of Target. Target has
not entered into any agreement to indemnify any other person against any charge
of infringement of any Target Proprietary Rights, except in the ordinary course
consistent with normal commercial practice for businesses of its type.

          (h) Target has taken all steps customary and reasonable in the
industry to protect and preserve the confidentiality and proprietary nature of
all Intellectual Property and other confidential information not otherwise
protected by patents, patent applications or copyright ("CONFIDENTIAL
INFORMATION"). All use, disclosure or appropriation by Target or, to the best
knowledge of Target, by another party pursuant to rights granted to it by
Target, of Confidential Information owned by Target to a third party has been
pursuant to the terms of a written agreement between Target and such third 
party. All use, disclosure or appropriation by Target of Confidential 
Information not owned by Target has been pursuant to the terms of a written
agreement between Target and the owner of such Confidential Information, or is
otherwise lawful.

                  (i) The information contained in the Target consumer database
described in Schedule 3.8(i) hereto was gathered in the normal course of
Target's business pursuant to bona fide Target transactions and, to Target's
knowledge, is true and complete in all material respects. The number of users
entered into such database via registration is listed in Schedule 3.8(i).

         Section 3.9     Employee Benefit Plans.

          (a)  The Target Disclosure Schedule lists, with respect to Target and
any trade or business (whether or not incorporated) which is treated as a single
employer with Target (an "ERISA AFFILIATE") within the meaning of Section
414(b), (c), (m) or (o) of the Code, (i) all employee benefit plans (as defined
in Section 3(3) of the Employee Retirement Income Security

                                     - 17 -




Act of 1974, as amended ("ERISA"), (ii) each loan to a non-officer employee,
loans to officers and directors and any stock option, stock purchase,
phantom stock, stock appreciation right, supplemental retirement, severance,
sabbatical, medical, dental, vision care, disability, employee relocation,
cafeteria benefit (Code Section 125) or dependent care (Code Section 129), life
insurance or accident insurance plans, programs or arrangements, (iii) all
bonus, pension, profit sharing, savings, deferred compensation or incentive
plans, programs or arrangements, (iv) other fringe or employee benefit plans,
programs or arrangements that apply to senior management of Target and that do
not generally apply to all employees, and (v) any current or former employment
or executive compensation or severance agreements, written or otherwise, for the
benefit of, or relating to, any present or former employee, consultant or
director of Target as to which (with respect to any of items (i) through (v)
above) any potential liability is borne by Target (together, the "TARGET
EMPLOYEE PLANS").

          (b)  Target has delivered to Acquiror or its representatives a copy
of each of the Target Employee Plans and related plan documents (including trust
documents, insurance policies or contracts, employee booklets, summary plan
descriptions and other authorizing documents, and, to the extent still in its
possession, any material employee communications relating thereto) and has, with
respect to each Target Employee Plan which is subject to ERISA reporting
requirements, provided copies of any Form 5500 reports filed for the last three
plan years. Any Target Employee Plan intended to be qualified under Section
401(a) of the Code has either obtained from the Internal Revenue Service a
favorable determination letter as to its qualified status under the Code,
including all amendments to the Code effected by the Tax Reform Act of 1986 and
subsequent legislation, or has applied to the Internal Revenue Service for such
a determination letter prior to the expiration of the requisite period under
applicable Treasury Regulations or Internal Revenue Service pronouncements in
which to apply for such determination letter and to make any amendments
necessary to obtain a favorable determination. Target has also furnished
Acquiror with the most recent Internal Revenue Service determination letter
issued with respect to each such Target Employee Plan, and nothing has occurred
since the issuance of each such letter which could reasonably be expected to
cause the loss of the tax-qualified status of any Target Employee Plan subject
to Code Section 401(a).

          (c)  (i)  None of the Target Employee Plans promises or provides
retiree medical or other retiree welfare benefits to any person; (ii) there has
been no "prohibited transaction," as such term is defined in Section 406 of
ERISA and Section 4975 of the Code, with respect to any Target Employee Plan;
(iii) each Target Employee Plan has been administered in accordance with its
terms and in compliance with the requirements prescribed by any and all
statutes, rules and regulations (including ERISA and the Code), and Target and
each subsidiary or ERISA Affiliate have performed all material obligations
required to be performed by them under, are not in any material respect in
default, under or violation of, and have no knowledge of any material default
or violation by any other party to, any of the Target Employee Plans; 
(iv) neither Target nor any subsidiary or ERISA Affiliate is subject to any
liability or penalty under Sections 4976 through 4980 of the Code or Title I of
ERISA with respect to any of the Target Employee Plans; (v) all contributions
required to be made by Target or any subsidiary or ERISA Affiliate to any Target
Employee Plan have been made on or before their due dates and a reasonable 
amount has been accrued for contributions to each Target Employee Plan for

                                     - 18 -




the current plan years; (vi) with respect to each Target Employee Plan, no
"reportable event" within the meaning of Section 4043 of ERISA (excluding any
such event for which the thirty (30) day notice requirement has been waived
under the regulations to Section 4043 of ERISA) nor any event described in
Section 4062, 4063 or 4041 of ERISA has occurred; and (vii) no Target Employee
Plan is covered by, and neither Target nor any subsidiary or ERISA Affiliate has
incurred or expects to incur any material liability under Title IV of ERISA or
Section 412 of the Code. With respect to each Target Employee Plan subject to
ERISA as either an employee pension plan within the meaning of Section 3(2) of
ERISA or an employee welfare benefit plan within the meaning of Section 3(1) of
ERISA, Target has prepared in good faith and timely filed all requisite
governmental reports (which were true and correct as of the date filed) and has
properly and timely filed and distributed or posted all notices and reports to
employees required to be filed, distributed or posted with respect to each such
Target Employee Plan. No suit, administrative proceeding, action or other
litigation has been brought, or to the knowledge of Target is threatened,
against or with respect to any such Target Employee Plan, including any audit or
inquiry by the IRS or United States Department of Labor. Neither Target nor any
ERISA Affiliate is a party to, or has made any contribution to or otherwise
incurred any obligation under, any "multi-employer plan" as defined in Section
3(37) of ERISA.

          (d)  With respect to each Target Employee Plan, Target has complied
with (i) the applicable health care continuation and notice provisions of the
Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA") and the
proposed regulations thereunder, (ii) the applicable requirements of the Family
Leave Act of 1993 and the regulations thereunder, and (iii) the applicable
requirements of the Health Insurance Portability and Accountability Act of 1996
("HIPAA") and the temporary regulations thereunder.

          (e)  The consummation of the transactions contemplated by this
Agreement will not (i) entitle any current or former employee or other service
provider of Target or any other ERISA Affiliate to severance benefits or any
other payment (including, without limitation, unemployment compensation, golden
parachute or bonus), except as expressly provided in this Agreement, or 
(ii) accelerate the time of payment or vesting of any such benefits, or 
(iii) increase or accelerate any benefits or the amount of compensation due any
such employee or service provider.

          (f)  There has been no amendment to, written interpretation or 
announcement (whether or not written) by Target or other ERISA Affiliate 
relating to, or change in participation or coverage under, any Target Employee
Plan which would materially increase the expense of maintaining such Plan above
the level of expense incurred with respect to that Plan for the most recent
fiscal year included in the Target Financial Statements.

      Section 3.10  Bank Accounts. The Target Disclosure Schedule sets forth the
names and locations of all banks, trust companies, savings and loan
associations, and other financial institutions at which Target maintains
accounts of any nature and the names of all persons authorized to draw thereon
or make withdrawals therefrom.

                                     - 20 -




                (x) Target has no outstanding loan or advance to any person;

Schedule are valid, binding, in full force and effect, and enforceable by
Target in accordance with their respective terms. No Material Contract contains

Target, no party to any such Material Contract intends to cancel, withdraw, 
modify or amend such contract, agreement or arrangement.

          (c)  Target is not in default under or in breach or violation of, 
nor, to Target's knowledge, is there any valid basis for any claim of default
by Target under, or breach or violation by Target of, any material provision of
any Material Contract. To Target's knowledge, no other party is in default 
under or in breach or violation of, nor is there any valid basis for any claim
of default by any other party under or any breach or violation by any other 
party of, any Material Contract.

          (d)  Except as specifically indicated on the Target Disclosure 
Schedule, none of the Material Contracts provides for indemnification by Target
of any third party, except in the ordinary course and consistent with normal
commercial practice for businesses of its type. No claims have been made or
threatened that would require indemnification by Target, and Target has not
paid any amounts to indemnify any third party as a result of indemnification
requirements of any kind.

customers.  Target has complied in all  material  respects at all times with
any and all applicable federal, state and foreign laws, rules, regulations,
proclamations  and orders  relating to the  importation  or  exportation  of its
products except for such noncompliances as would not in the aggregate reasonably
be expected to have a Material Adverse Effect.

with, and give all notices to, third parties which may be necessary or
reasonably required on its part in order to effect the transactions contemplated
by this Agreement. Target shall use its best efforts to obtain any and all
consents necessary with respect to those Material Contracts listed on Schedule
5.5 of the Target Disclosure Schedule in connection with the Merger (the
"MATERIAL CONSENTS").

      Section 5.6   Other Negotiations. Following the date hereof and until
termination of this Agreement pursuant to Section 9.1, Target will not (and it
will not permit any of its officers, directors, employees, agents and Affiliates
on its behalf to) take any action to solicit, initiate, seek, encourage or
support any inquiry, proposal or offer from, furnish any information to, or
participate in any negotiations with, any corporation, partnership, person or
other entity or group (other than Acquiror) regarding any acquisition of Target,
any merger or consolidation with or involving Target, or any acquisition of any
material portion of the stock or assets of Target or any material license of
Target Proprietary Rights (any of the foregoing being referred to in this
Agreement as an "ACQUISITION TRANSACTION") or enter into an agreement concerning
any Acquisition Transaction with any party other than Acquiror. If between the
date of this Agreement and the termination of this Agreement pursuant to Section
9.1, Target receives from a third party any offer or indication of interest
regarding any Acquisition Transaction, or any request for information regarding
any Acquisition Transaction, Target shall (i) notify Acquiror immediately
(orally and in writing) of such offer, indication of interest or request,
including the identity of such party and the full terms of any proposal therein,
and (ii) notify such third party of Target's obligations under this Agreement.

                                   ARTICLE VI

               PRECLOSING AND OTHER COVENANTS OF ACQUIROR AND SUB


                                     - 32 -




         Section 6.1     Advice of Changes. Acquiror and Sub will promptly
advise Target in writing of any event occurring subsequent to the date of this
Agreement which would render any representation or warranty of Acquiror or Sub
contained in this Agreement, if made on or as of the date of such event or the
Closing Date, untrue or inaccurate in any material respect.

      Section 6.2   Reservation of Acquiror Common Stock. Acquiror shall reserve
for issuance, out of its authorized but unissued capital stock, the maximum
number of shares of Acquiror Common Stock as may be issuable upon consummation
of the Merger.

      Section 6.3   Satisfaction of Conditions Precedent. Acquiror and Sub will
use their reasonable best efforts to satisfy or cause to be satisfied all the
conditions precedent which are set forth in Sections 8.1 and 8.3, and Acquiror
and Sub will use their reasonable best efforts to cause the transactions
contemplated by this Agreement to be consummated, and, without limiting the
generality of the foregoing, to obtain all consents and authorizations of third
parties and to make all filings with, and give all notices to, third parties
which may be necessary or reasonably required on its part in order to effect the
transactions contemplated hereby.

      Section 6.4   Nasdaq National Market Listing. Acquiror shall cause the
shares of Acquiror Common Stock issuable to the stockholders of Target in the
Merger to be authorized for listing on the Nasdaq National Market.

      Section 6.5   Stock Options and Warrants.

          (a)  At the Effective Time, each outstanding Target Option under the
Target Option Plan, whether vested or unvested, shall be assumed by Acquiror and
deemed to constitute an option (a "ACQUIROR OPTION") to acquire, on the same
terms and conditions as were applicable under the Target Option, the same number
of shares of Acquiror Common Stock as the holder of such Target Option would 
have been entitled to receive pursuant to the Merger had such holder exercised
such option in full immediately prior to the Effective Time (rounded down to the
nearest whole number), at a price per share (rounded up to the nearest whole 
cent) equal to (i) the aggregate exercise price for the shares of Target Common
Stock otherwise purchasable pursuant to such Target Option divided by (ii) the
number of full shares of Acquiror Common Stock deemed purchasable pursuant to 
such Acquiror Option in accordance with the foregoing; provided, however, that,
in the case of any Target Option to which Section 422 of the Code applies
("INCENTIVE STOCK OPTIONS"), the option price, the number of shares purchasable
pursuant to such option and the terms and conditions of exercise of such option
shall be determined in order to comply with Section 424(a) of the Code. In
connection with the assumption by Acquiror of the Target Options pursuant to
this Section 6.5(a), Target shall be deemed to have assigned to Acquiror,
effective at the Effective Time, Target's right to repurchase unvested shares of
Target Common Stock issuable upon the exercise of the Target Options or
previously issued upon the exercise of options granted under the Target Option
Plan, in accordance with the terms of the Target Option Plan and the related
stock option agreements and stock purchase agreements entered into under the
Target Option Plan.

          (b)  As soon as practicable after the Effective Time, Acquiror shall
deliver to the participants in the Target Option Plan appropriate notice setting
forth such participants' rights

                                     - 33 -




pursuant thereto and the grants pursuant to the Target Option Plan shall
continue in effect on the same terms and conditions (subject to the adjustments
required by this Section 6.5 after giving effect to the Merger). Acquiror shall
comply with the terms of the Target Option Plan and use best efforts to ensure,
to the extent required by, and subject to the provisions of, such Target Option
Plan and Sections 422 and 424(a) of the Code, that Target Options which
qualified as incentive stock options prior the Effective Time continue to
qualify as incentive stock options after the Effective Time.

          (c)  Acquiror shall take all corporate action necessary to reserve for
issuance a sufficient number of shares of Acquiror Common Stock for delivery
upon exercise of Target Options assumed in accordance with this Section 6.5. No
later than the fifth business day after the Closing Date, Acquiror shall file a
registration statement on Form S-8 (or any successor or other appropriate forms)
under the Securities Act or another appropriate form with respect to the shares
of Acquiror Common Stock subject to such options and shall use its best efforts
to maintain the effectiveness of such registration statement or registration
statements (and maintain the current status of the prospectus or prospectuses
contained therein) for so long as such options remain outstanding.

          (d)  Each Target Warrant, to the extent outstanding at the Effective
Time, whether or not exercisable and whether or not vested at the Effective 
Time, shall remain outstanding at the Effective Time. At the Effective Time,
Target Warrants shall, by virtue of the Merger and without any further action on
the part of Target or the holder of any of Target Warrants (unless further
action may be required by the terms of any of Target Warrants), be assumed by
Acquiror and each Target Warrant assumed by Acquiror shall be exercisable upon
the same terms and conditions as under the applicable warrant agreements with
respect to such Target Warrants, except that (A) each such Target Warrant shall
be exercisable for that whole number of shares of Acquiror Common Stock (rounded
down to the nearest whole share) into which the number of shares of Target
Common Stock subject to such Target Warrant would be converted under Section
2.1(c), and (B) the exercise price per share of Acquiror Common Stock shall be
an amount equal to the exercise price per share of Target Common Stock subject
to such Target Warrant in effect immediately prior to the Effective Time divided
by the applicable Exchange Ratio (the exercise price per share, so determined,
being rounded to the nearest full cent). From and after the Effective Time, all
references to Target in the warrant agreements underlying Target Warrants shall
be deemed to refer to Acquiror. Acquiror further agrees that, notwithstanding
any other term of this Section 6.5(d) to the contrary, if required under the
terms of Target Warrants or if otherwise appropriate under the terms of Target
Warrants, it will execute a supplemental agreement with the holders of Target
Warrants to effectuate the foregoing. No payment shall be made for fractional
shares. Acquiror shall (i) on or prior to the Effective Time, reserve for
issuance the number of shares of Acquiror Common Stock that will become subject
to warrants to purchase Acquiror Common Stock ("ACQUIROR WARRANTS") pursuant to
this Section 6.5(d), (ii) from and after the Effective Time, upon exercise of
the Acquiror Warrants in accordance with the terms thereof, make available for
issuance all shares of Acquiror Common Stock covered thereby and (iii) as
promptly as practicable following the Effective Time, issue to each holder of an
outstanding Target Warrant a document evidencing the foregoing assumption by
Acquiror.

                                     - 34 -




         Section 6.6       Registration of Shares Issued in the Merger.

          (a)  Registrable Shares. For purposes of this Agreement, "REGISTRABLE
SHARES" shall mean the shares of Acquiror Common Stock issued in the Merger,
including any and all Escrow Shares, and the shares of Acquiror Common Stock
issuable upon the exercise of the Target Warrants assumed by Acquiror pursuant
to Section 6.5(d), but excluding shares of Acquiror Common Stock issued in the
Merger or issuable upon the exercise of the Target Warrants that have been sold
or otherwise transferred by the stockholders of Target who initially received
such shares in the Merger or by the holder of the Target Warrants prior to the
effective date of the Registration Statement (as defined below) (collectively,
the "HOLDERS"); provided however, that a distribution of shares of Acquiror
Common Stock issued in the Merger without additional consideration, to
underlying beneficial owners (such as the general and limited partners,
stockholders or trust beneficiaries of a Holder) shall not be deemed such a sale
or transfer for purposes of this Section 6.6 and such underlying beneficial
owners shall be entitled to the same rights under this Section 6.6 as the
initial Holder from which the Registrable Shares were received and shall be
deemed a Holder for the purposes of this Section 6.6.

          (b)  Required Registration. No later than the fifth business day
following the Effective Time, Acquiror shall prepare and file with the
Commission a registration statement on Form S-3 (or such successor or other 
appropriate form) under the Securities Act with respect to the Registrable
Shares (the "REGISTRATION STATEMENT") and shall effect all such registrations,
qualifications and compliances (including, without limitation, obtaining
appropriate qualifications under applicable state securities or "blue sky" laws
and compliance with any other applicable governmental requirements or
regulations) as any selling Holder may reasonably request and that would permit
or facilitate the sale of all Registrable Shares (provided however that Acquiror
shall not be required in connection therewith to qualify to do business or to
file a general consent to service of process in any such state or jurisdiction),
and in each case Acquiror will use its best efforts to cause such Registration
Statement and all other such registrations, qualifications and compliances to
become effective as soon as practicable thereafter.

          (c)  Effectiveness; Suspension Right.

               (i)  Acquiror will use its best efforts to maintain the 
effectiveness of the Registration Statement and other applicable registrations,
qualifications and compliances for up to one (1) year from the Closing Date (the
"REGISTRATION EFFECTIVE PERIOD"), and from time to time will amend or supplement
the Registration Statement and the prospectus contained therein as and to the 
extent necessary to comply with the Securities Act, the Exchange Act and any
applicable state securities statute or regulation, subject to the following 
limitations and qualifications.

               (ii) Following the date on which the Registration Statement is
first declared effective, the Holders will be permitted (subject in all cases to
the terms of the Stockholders Agreements and to Section 6.7 below) to offer and
sell Registrable Shares during the Registration Effective Period in the manner
described in the Registration Statement provided that the Registration Statement
remains effective and has not been suspended.

                                     - 35 -




              (iii) Notwithstanding any other provision of this Section 6.6 but
subject to Section 6.7, Acquiror shall have the right at any time to require
that all Holders suspend further open market offers and sales of Registrable
Shares whenever, and for so long as, in the reasonable judgment of Acquiror
after consultation with counsel there is or may be in existence material
undisclosed information or events with respect to Acquiror (the "SUSPENSION
RIGHT"). In the event Acquiror exercises the Suspension Right, such suspension
will continue for the period of time reasonably necessary for disclosure to 
occur at a time that is not detrimental to Acquiror and its shareholders or 
until such time as the information or event is no longer material, each as 
determined in good faith by Acquiror after consultation with counsel. Acquiror
will promptly give the Holders notice of any such suspension and will use all 
reasonable efforts to minimize the length of the suspension.

          (d)  Expenses. The costs and expenses to be borne by Acquiror for 
purposes of this Section 6.6 shall include, without limitation, printing 
expenses (including a reasonable number of prospectuses for circulation by the 
selling Holders), legal fees and disbursements of counsel for Acquiror, "blue
sky" expenses, accounting fees and filing fees, but shall not include 
underwriting commissions or similar charges, or any legal fees and disbursements
of counsel for the selling Holders.

          (e)  Indemnification.

               (i) To the extent permitted by law, Acquiror will indemnify and
hold harmless each Holder, any underwriter (as defined in the Securities Act)
for such Holder, its officers, directors, stockholders or partners and each
person, if any, who controls such Holder or underwriter within the meaning of
the Securities Act or the Exchange Act, against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the
Securities Act, the Exchange Act or other federal or state law, insofar as such
losses, claims, damages, or liabilities (or actions in respect thereof) arise
out of or are based upon any of the following statements, omissions or
violations (collectively a "VIOLATION"): (A) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement,
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto, (B) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (C) any violation or alleged
violation by Acquiror of the Securities Act, the Exchange Act, any state
securities law or any rule or regulation promulgated under the Securities Act,
the Exchange Act or any state securities law; and Acquiror will pay to each such
Holder (and its officers, directors, stockholders or partners), underwriter or
controlling person, any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this Section 6.6(e)(i) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability, or action if such settlement is effected
without the consent of Acquiror; nor shall Acquiror be liable in any such case
for any such loss, claim, damage, liability, or action to the extent that it
arises out of or is based upon (a) a Violation which occurs in reliance upon and
in conformity with written information furnished expressly for use in the
Registration Statement by any such Holder, or (b) a Violation that would not
have occurred if such Holder had delivered to

                                     - 36 -




the purchaser the version of the Prospectus most recently provided by Acquiror
to the Holder as of the date of such sale.

               (ii) To the extent permitted by law, each selling Holder will
indemnify and hold harmless Acquiror, each of its directors, each of its
officers who has signed the Registration Statement, each person, if any, who
controls Acquiror within the meaning of the Securities Act, any underwriter, any
other Holder selling securities pursuant to the Registration Statement and any
controlling person of any such underwriter or other Holder, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Securities Act, the Exchange Act or other
federal or state law, insofar as such losses, claims, damages, or liabilities
(or actions in respect thereto) arise out of or are based upon any Violation 
(which includes without limitation the failure of the Holder to comply with the
prospectus delivery requirements under the Securities Act, and the failure of
the Holder to deliver the most current prospectus provided by Acquiror prior to
such sale), in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Holder expressly for use in the Registration Statement or such
Violation is caused by the Holder's failure to deliver to the purchaser of the
Holder's Registrable Shares a prospectus (or amendment or supplement thereto)
that had been made available to the Holder by Acquiror; and each such Holder
will pay any legal or other expenses reasonably incurred by any person intended
to be indemnified pursuant to this Section 6.6(e)(ii) in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this Section
6.6(e)(ii) shall not apply to amounts paid in settlement of any such loss,
claim, damage, liability or action if such settlement is effected without the
consent of the Holder, which consent shall not be unreasonably withheld. The
aggregate indemnification and contribution liability of each Holder under this
Section 6.6(e)(ii) shall not exceed the net proceeds received by such Holder in
connection with sale of shares pursuant to the Registration Statement.

              (iii) Each person entitled to indemnification under this Section
6.6(e) (the "INDEMNIFIED PARTY") shall give notice to the party required to 
provide indemnification (the "Indemnifying Party") promptly after such 
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought and shall permit the Indemnifying Party to assume the defense of any such
claim and any litigation resulting therefrom, provided that counsel for the 
Indemnifying Party who conducts the defense of such claim or any litigation
resulting therefrom shall be approved by the Indemnified Party (whose approval
shall not unreasonably be withheld), and the Indemnified Party may participate
in such defense at such party's expense, and provided further that the failure 
of any Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Section 6.6 unless the
Indemnifying Party is materially prejudiced thereby. No Indemnifying Party, in
the defense of any such claim or litigation, shall (except with the consent of
each Indemnified Party) consent to entry of any judgment or enter into any
settlement that does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect to such claim or litigation. Each Indemnified Party shall
furnish such information regarding itself or the claim in question as an
Indemnifying Party may reasonably request in

                                            - 37 -




writing and as shall be reasonably required in connection with the defense of
such claim and litigation resulting therefrom.

               (iv) To the extent that the indemnification provided for in this
Section 6.6(e) is held by a court of competent jurisdiction to be unavailable to
an Indemnified Party with respect to any loss, liability, claim, damage or
expense referred to herein, then the Indemnifying Party, in lieu of indemnifying
such Indemnified Party hereunder, shall contribute to the amount paid or payable
by such Indemnified Party as a result of such loss, liability, claim, damage or
expense in such proportion as is appropriate to reflect the relative fault of
the Indemnifying Party on the one hand and of the Indemnified Party on the other
in connection with the statements or omissions which resulted in such loss,
liability, claim, damage or expense, as well as any other relevant equitable
considerations. The relative fault of the Indemnifying Party and of the
Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Indemnifying Party or by the Indemnified Party and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

      Section 6.7   Procedures for Sale of Shares Under Registration Statement.

          (a)  Notice and Approval. If any Holder shall propose to sell any
Registrable Shares pursuant to the Registration Statement, it shall notify
Acquiror of its intent to do so (including the proposed manner and timing of all
sales) at least two (2) full trading days prior to such sale, and the provision
of such notice to Acquiror shall conclusively be deemed to reestablish and
reconfirm an agreement by such Holder to comply with the registration provisions
set forth in this Agreement. Unless otherwise specified in such notice, such
notice shall be deemed to constitute a representation that any information
previously supplied by such Holder expressly for inclusion in the Registration
Statement (as the same may have been superseded by subsequent such information)
is accurate as of the date of such notice. At any time within such two (2)
trading-day period, Acquiror may delay, consistent with Acquiror's obligations
under Section 6.6(c)(iii) to minimize any delay, the resale by such Holder of
any Registrable Shares pursuant to the Registration Statement only if a sale
pursuant to the Registration Statement in its then current form without the
addition of material, non-public information about Acquiror could reasonably
constitute a violation of the federal securities laws; provided, however, that
in order to exercise this right, Acquiror must deliver a certificate in writing
to the Holder to such effect. Notwithstanding the foregoing, Acquiror will
ensure that in any event the Holders shall have at least twenty (20) trading
days (prorated for partial quarters) available to sell Registrable Shares during
each calendar quarter (or portion thereof) during the Registration Effective
Period.

          (b)  Delivery of Prospectus. For any offer or sale of any of the
Registrable Shares by a Holder in a transaction that is not exempt under the
Securities Act, the Holder, in addition to complying with any other federal
securities laws, shall deliver a copy of the final prospectus (or amendment of
or supplement to such prospectus) of Acquiror covering the 

                                     - 38 -




Registrable Shares in the form furnished to the Holder by Acquiror to the
purchaser of any of the Registrable Shares on or before the settlement date for
the purchase of such Registrable Shares.

          (c)  Copies of Prospectuses. Subject to the provisions of this Section
6.7, when a Holder is entitled to sell and gives notice of its intent to sell
Registrable Shares pursuant to the Registration Statement, Acquiror shall,
within two (2) trading days following the request, furnish to such Holder a
reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such Registrable Shares, such prospectus shall not as of the date
of delivery to the Holder include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading or incomplete in the light of the
circumstances then existing.

      Section 6.8   Certain Employee Benefit Matters. From and after the 
Effective Time, employees of Target at the Effective Time will be provided with
employee benefits by the Surviving Corporation or Acquiror which in the 
aggregate are no less favorable to such employees than those provided from time
to time by Acquiror to similarly situated employees. If any employee of Target
becomes a participant in any employee benefit plan, program, policy or 
arrangement of Acquiror, such employee shall be given credit for all service
prior to the Effective Time with Target to the extent permissible under such 
plan, program, policy or arrangement. Employees of Target as of the Effective 
Time shall be permitted to participate in the Yahoo! Inc. 1996 Employee Stock 
Purchase Plan ("ESPP") commencing on the first enrollment date following the 
Effective Time, subject to compliance with the eligibility and other provisions
of such plan.

      Section 6.9   Director and Officer Liability. For six years after the
Effective Time, Acquiror will ensure that the Surviving Corporation (or Acquiror
will directly, in the event the Surviving Corporation is dissolved or wound up)
will indemnify and hold harmless the present and former officers, directors,
employees and agents of Target (the "Indemnified Parties") in respect of acts or
omissions occurring on or prior to the Effective Time to the extent provided
under Target's certificate of incorporation and bylaws in effect on the date
hereof; provided, that such indemnification shall be subject to any limitation
imposed from time to time under applicable law. In addition, Acquiror will
include the Indemnified Parties in any directors/officers insurance policy
otherwise obtained by Acquiror to the extent Acquiror can do so without
significant additional expense.

announcement concerning this Agreement, their discussions or any other
memoranda, letters or agreements between the parties relating to the Merger;
provided, however, that either of the parties, but only after reasonable

reasonable good faith efforts to cause the business combination to be effected
by the Merger to be accounted for as a pooling of interests. Neither Target nor
Acquiror shall take any action that would adversely affect the ability of
Acquiror to account for the business combination to be effected by the Merger as
a pooling of interests.

capital stock of Target do not constitute "United States real property
interests" under Section 897(c) of the Code, for purposes of satisfying
Acquiror's obligations under Treasury Regulation Section 1.14452(c)(3). In
addition, simultaneously with delivery of such FIRPTA Notification Letter,
Target shall provide to


                                     - 40 -




Acquiror, as agent for Target, a form of notice to the Internal Revenue
Service in accordance with the requirements of Treasury Regulation Section
1.8972(h)(2), along with written authorization for Acquiror to deliver such
notice form to the Internal Revenue Service on behalf of Target upon the Closing
of the Merger.

      Section 7.8   Blue Sky Laws. Acquiror shall take such steps as may be
necessary to comply with the securities and blue sky laws of all jurisdictions
which are applicable to the issuance of the Acquiror Common Stock in connection
with the Merger. Target shall use its reasonable good faith efforts to assist
Acquiror as may be necessary to comply with the securities and blue sky laws of
all jurisdictions which are applicable in connection with the issuance of
Acquiror Common Stock in connection with the Merger.

      Section 7.9   Other Filings. As promptly as practicable after the date of

law and the rules and regulations promulgated thereunder. Whenever any event
occurs which is required to be set forth in an amendment or supplement to the
Other Filings, Target or Acquiror, as the case may be, will promptly inform the
other of such occurrence and cooperate in making any appropriate amendment or
supplement, and/or mailing to stockholders of Target, such amendment or
supplement.

                                   ARTICLE IX

                            TERMINATION AND AMENDMENT

      Section 9.1   Termination. This Agreement may be terminated at any time
prior to the Effective Time:

           (a) by mutual written consent of Acquiror and Target;

           (b) by either Acquiror or Target, by giving written notice to the
other party, if a court of competent jurisdiction or other Governmental Entity
shall have issued a nonappealable final order, decree or ruling or taken any
other action, in each case having the effect of permanently restraining, 
enjoining or otherwise prohibiting the Merger, except, if such party relying on
such order, decree or ruling or other action shall not have complied with its 
respective obligations under Sections 5.5 or 6.3 of this Agreement, as the case
may be;

          (c)  by Acquiror or Target, by giving written notice to the other 
party, if the other party is in material breach of any representation, warranty,
or covenant of such other party contained in this Agreement, which breach shall
not have been cured, if subject to cure, within 10 business days following 
receipt by the breaching party of written notice of such breach by the other 
party;

          (d)  by Acquiror, by giving written notice to Target, if the Closing
shall not have occurred on or before December 1, 1998 by reason of the failure
of any condition precedent under Section 8.1 or 8.2 (unless the failure results
primarily from a breach by Acquiror of any representation, warranty, or covenant
of Acquiror contained in this Agreement or Acquiror's failure to fulfill a
condition precedent to closing or other default);

          (e)  by Target, by giving written notice to Acquiror, if the Closing
shall not have occurred on or before December 1, 1998 by reason of the failure
of any condition precedent

                                     - 44 -




under Section 8.1 or 8.3 (unless the failure results primarily from a breach by
Target of any representation, warranty, or covenant of Target contained in this
Agreement or Target's failure to fulfill a condition precedent to closing or 
other default); or

          (f)  by Acquiror, by giving written notice to Target, if the required
approvals of the stockholders of Target contemplated by this Agreement shall not
have been obtained by reason of the failure to obtain the required consents or
votes upon a vote taken by written consent or at a meeting of stockholders, duly
convened therefor or at any adjournment thereof.

      Section 9.2   Effect of Termination. In the event of termination of this
Agreement as provided in Section 9.1, this Agreement shall immediately become
void and there shall be no liability or obligation on the part of Acquiror,
Target, Sub or their respective officers, directors, stockholders or Affiliates,
except as set forth in Section 9.3 and further except to the extent that such
termination results from the willful breach by any such party of any of its
representations, warranties or covenants set forth in this Agreement.

      Section 9.3   Fees and Expenses.

          (a)  Except as set forth in this Section 9.3, all fees and expenses
incurred in connection with this Agreement and the transactions contemplated
hereby shall be paid by the party incurring such expenses, whether or not the
Merger is consummated. Target has submitted a budget to Acquiror for completion
of the Merger. Target shall use its best efforts to consummate the Merger within
such budget and shall not enter into any agreement inconsistent with such
budget.

          (b)  If the Merger is consummated, all legal, accounting, investment
banking, broker's and finder's fees and expenses incurred by Target or its
stockholders in connection with the Merger shall be deemed expenses of the
stockholders of Target to the extent such fees and expenses exceed $870,000, in
the case of broker's fees and $75,000 in the case of all other fees, and shall
be borne by the stockholders of Target to such extent and will not become
obligations of Target. Target will make arrangements for the payments of such
fees acceptable to Acquiror.

                                    ARTICLE X

                           ESCROW AND INDEMNIFICATION

      Section 10.1  Indemnification. From and after the Effective Time and
subject to the limitations contained in Section 10.2, the Former Target
Stockholders will, severally and pro rata, in accordance with their Pro Rata
Portion, indemnify and hold Acquiror harmless against any loss, expense,
liability or other damage, including attorneys' fees, to the extent of the
amount of such loss, expense, liability or other damage (collectively "DAMAGES")
that Acquiror has incurred by reason of the breach or alleged breach by Target
of any representation, warranty, covenant or agreement of Target contained in
this Agreement that occurs or becomes known to Acquiror during the Escrow Period
(as defined in Section 10.4 below). Acquiror, Target and Sub acknowledge and
agree, and the Former Target Stockholders, by their approval of this Agreement,
agree that notwithstanding anything to the contrary contained in this Agreement
or

                                     - 45 -




any other Transaction Document, such indemnification under this Article X
shall be the sole and exclusive remedy for any such claim of breach by Target,
except for Damages based upon a claim of fraud.

      Section 10.2  Escrow Fund. As security and the sole and exclusive recourse
for the indemnities in Section 10.1, as soon as practicable after the Effective
Time, the Escrow Shares shall be deposited with U.S. Bank Trust, National
Association (or such other institution selected by Acquiror with the reasonable
consent of Target) as escrow agent (the "ESCROW AGENT"), such deposit to
constitute the Escrow Fund (the "ESCROW FUND") and to be governed by the terms
set forth in this Article X and in the Escrow Agreement. Notwithstanding the
foregoing or anything to the contrary contained in this Agreement or in any
Transaction Document, the indemnification obligations of the Former Target
Stockholders pursuant to this Article X or otherwise shall be limited to the
amount and assets deposited and present in the Escrow Fund and Acquiror shall
not be entitled to pursue any claims for indemnification under this Article X or
otherwise against the Former Target Stockholders directly or personally, and the
sole recourse of Acquiror shall be to make claims against the Escrow Fund in
accordance with the terms of the Escrow Agreement.

      Section 10.3  Damage Threshold. Notwithstanding the foregoing, the Former
Target Stockholders shall have no liability under Section 10.1 and Acquiror may
not receive any shares from the Escrow Fund unless and until an Officer's
Certificate or Certificates (as defined in Section 10.5 below) for an aggregate
amount of Acquiror's Damages in excess of $50,000 has been delivered to the
Stockholders' Agents and to the Escrow Agent; provided, however, that after an
Officer's Certificate or Certificates for an aggregate of $50,000 in Damages has
been delivered, Acquiror shall be entitled to receive Escrow Shares equal in
value to the full amount of Damages identified in such Officer's Certificate or
Certificates; and provided further that any Acquiror Damages arising from or
relating to any breach of Section 3.25 shall not be subject to this Section 10.3
and shall be recoverable from the Escrow Fund without regard to any damage
threshold.

      Section 10.4  Escrow Periods. The Escrow Fund shall terminate upon the
earlier of (i) the first anniversary date of the Closing Date and (ii) the date
on which Acquiror's auditors deliver their opinion as to Acquiror's financial
statements for the fiscal year ending after the Effective Time (the period from
the Closing Date to such date referred to as the "ESCROW PERIOD"), provided,
however, that the number of Escrow Shares, which, in the reasonable judgment of
Acquiror, subject to the objection of the Stockholders' Agents and the
subsequent resolution of the matter in the manner provided in Section 10.8, are
necessary to satisfy any unsatisfied claims specified in any Officer's
Certificate theretofore delivered to the Escrow Agent and the Stockholders'
Agents prior to termination of the Escrow Period with respect to Damages
incurred or litigation pending prior to expiration of the Escrow Period, shall
remain in the Escrow Fund until such claims have been finally resolved.

      Section 10.5  Claims Upon Escrow Fund. Upon receipt by the Escrow Agent
on or before the last day of the Escrow Period of a certificate signed by any
appropriately authorized officer of Acquiror (an "OFFICER'S CERTIFICATE"):


                                     - 46 -




               (i)  Stating the aggregate amount of Acquiror's Damages or an
estimate thereof, in each case to the extent known or determinable at such time;
and

               (ii) Specifying in reasonable detail the individual items of such
Damages included in the amount so stated, the date each such item was paid or 
properly accrued or arose, and the nature of the misrepresentation, breach or 
claim to which such item is related, the Escrow Agent shall, subject to the 
provisions of Sections 10.3 and 10.8 hereof and of the Escrow Agreement, deliver
to Acquiror out of the Escrow Fund, as promptly as practicable, Escrow Shares
having a value equal to such Damages all in accordance with the Escrow Agreement
and Section 10.6 below. Amounts paid or distributed from the Escrow Fund shall
be paid or distributed pro rata among the Holders (as defined in the Escrow 
Agreement) based upon their respective percentage interests therein at the time.

      Section 10.6  Valuation. For the purpose of compensating Acquiror for its
Damages pursuant to this Agreement, the value per share of the Escrow Shares
which shall be released to Acquiror in respect of a claim for Damages shall be
the average closing price of Acquiror Common Stock for the five consecutive
trading days preceding the date of this Agreement.

      Section 10.7  Objections to Claims. At the time of delivery of any
Officer's Certificate to the Escrow Agent, a duplicate copy of such Officer's
Certificate shall be delivered to the Stockholders' Agents (as defined in
Section 10.9 below) and for a period of thirty (30) days after such delivery,
the Escrow Agent shall make no delivery of Escrow Shares pursuant to Section
10.4 unless the Escrow Agent shall have received written authorization from the
Stockholders' Agents to make such delivery. After the expiration of such thirty
(30) day period, the Escrow Agent shall make delivery of the Escrow Shares in
the Escrow Fund in accordance with Section 10.4, provided that no such delivery
may be made if the Stockholders' Agents shall object in a written statement to
the claim made in the Officer's Certificate, and such statement shall have been
delivered to the Escrow Agent and to Acquiror prior to the expiration of such
thirty (30) day period.

      Section 10.8  Resolution of Conflicts.

          (a)  In case the Stockholders' Agents shall so object in writing to 
any claim or claims by Acquiror made in any Officer's Certificate, Acquiror 
shall have thirty (30) days to respond in a written statement to the objection
of the Stockholders' Agents. If after such thirty (30) day period there remains
a dispute as to any claims, the Stockholders' Agents and Acquiror shall attempt
in good faith for thirty (30) days to agree upon the rights of the respective
parties with respect to each of such claims. If the Stockholders' Agents and
Acquiror should so agree, a memorandum setting forth such agreement shall be
prepared and signed by both parties and shall be furnished to the Escrow Agent.
The Escrow Agent shall be entitled to rely on any such memorandum and shall
distribute the Escrow Shares from the Escrow Fund in accordance with the terms
of the memorandum.

          (b)  If no such agreement can be reached after good faith negotiation,
either Acquiror or the Stockholders' Agents may, by written notice to the other,
demand arbitration of the matter unless the amount of the damage or loss is at
issue in pending litigation with a third

                                     - 47 -




party, in which event arbitration shall not be commenced until such amount is
ascertained or both parties agree to arbitration; and in either such event
the matter shall be settled by arbitration conducted by three arbitrators.
Within fifteen (15) days after such written notice is sent, Acquiror (on the one
hand) and the Stockholders' Agents (on the other hand) shall each select one
arbitrator, and the two arbitrators so selected shall select a third arbitrator.
The decision of the arbitrators as to the validity and amount of any claim in
such Officer's Certificate shall be binding and conclusive upon the parties to
this Agreement, and notwithstanding anything in Section 10.4, the Escrow Agent
shall be entitled to act in accordance with such decision and make or withhold
payments out of the Escrow Fund in accordance with such decision.

          (c)  Judgment upon any award rendered by the arbitrators may be 
entered in any court having jurisdiction. Any such arbitration shall be held in 
Santa Clara or San Mateo County, California under the commercial rules then in 
effect of the American Arbitration Association. The non-prevailing party to an
arbitration shall pay its own expenses, the fees of each arbitrator, the 
administrative fee of the American Arbitration Association, and the expenses, 
including, without limitation, the reasonable attorneys' fees and costs, 
incurred by the prevailing party to the arbitration.

      Section 10.9  Stockholders' Agents.

           (a) Seth Godin and Frederick R. Wilson shall be constituted and 
appointed as agents (the "STOCKHOLDERS' AGENTS") for and on behalf of the Former
Target Stockholders to give and receive notices and communications, to authorize
delivery to Acquiror of the Escrow Shares or other property from the Escrow Fund
in satisfaction of claims by Acquiror, to object to such deliveries, to agree
to, negotiate, enter into settlements and compromises of, and demand arbitration
and comply with orders of courts and awards of arbitrators with respect to such
claims, and to take all actions necessary or appropriate in the judgment of the
Stockholders' Agents for the accomplishment of the foregoing. All actions of the
Stockholders' Agents shall be taken jointly, not individually. Such agency may
be changed by the holders of a majority in interest of the Escrow Shares from
time to time upon not less than ten (10) days' prior written notice to Acquiror.
No bond shall be required of the Stockholders' Agents, and the Stockholders'
Agents shall receive no compensation for services. Notices or communications to
or from the Stockholders' Agents shall constitute notice to or from each of the
Former Target Stockholders.

          (b)  The Stockholders' Agents shall not be liable for any act done or
omitted hereunder as Stockholders' Agent while acting in good faith, and any act
done or omitted pursuant to the advice of counsel shall be conclusive evidence
of such good faith. The Former Target Stockholders shall severally and pro rata,
in accordance with their Pro Rata Portion, indemnify the Stockholders' Agents
and hold them harmless against any loss, liability or expense incurred without
gross negligence or bad faith on the part of the Stockholders' Agents and
arising out of or in connection with the acceptance or administration of their
duties hereunder under this Agreement or the Escrow Agreement.


                                     - 48 -




          (c)  The Stockholders' Agents shall have reasonable access to 
information about Target and Acquiror and the reasonable assistance of Target's
and Acquiror's officers and employees for purposes of performing their duties
and exercising their rights under this Article X, provided that the 
Stockholders' Agents shall treat confidentially and not disclose any nonpublic 
information from or about Target or Acquiror to anyone (except on a need to know
basis to individuals who agree to treat such information confidentially).

      Section 10.10 Actions of the Stockholders' Agents. A decision, act,
consent or instruction of the Stockholders' Agents shall constitute a decision
of all of the Former Target Stockholders for whom shares of Acquiror Common
Stock otherwise issuable to them are deposited in the Escrow Fund and shall be
final, binding and conclusive upon each such Former Target Stockholder, and the
Escrow Agent and Acquiror may rely upon any decision, act, consent or
instruction of the Stockholders' Agents as being the decision, act, consent or
instruction of each and every such Former Target Stockholder. The Escrow Agent
and Acquiror are hereby relieved from any liability to any person for any acts
done by them in accordance with such decision, act, consent or instruction of
the Stockholders' Agents.

      Section 10.11 Claims. In the event Acquiror becomes aware of a third-party
claim which Acquiror believes may result in a demand against the Escrow Fund,
Acquiror shall promptly notify the Stockholders' Agents of such claim, and the
Stockholders' Agents and the Former Target Stockholders for whom shares of
Acquiror Common Stock otherwise issuable to them are deposited in the Escrow
Fund shall be entitled, at their expense, to participate in any defense of such
claim. Acquiror shall have the right in its sole discretion to settle any such
claim; provided, however, that Acquiror may not effect the settlement of any
such claim without the consent of the Stockholders' Agents, which consent shall
not be unreasonably withheld. In the event that the Stockholders' Agents have
consented to any such settlement, the Stockholders' Agents shall have no power
or authority to object to the amount of any claim by Acquiror against the Escrow
Fund for indemnity with respect to such settlement in the amount agreed to.

                                   ARTICLE XI

                                  MISCELLANEOUS

      Section 11.1  Survival of Representations and Covenants. All
representations, warranties, covenants and agreements of Target contained in
this Agreement shall survive the Closing and any investigation at any time made
by or on behalf of Acquiror until the end of the Escrow Period. If Escrow Shares
or other assets are retained in the Escrow Fund beyond expiration of the period
specified in the Escrow Agreement, then (notwithstanding the expiration of such
time period) the representation, warranty, covenant or agreement applicable to
such claim shall survive until, but only for purposes of, the resolution of the
claim to which such retained Escrow Shares or other assets relate. All
representations, warranties, covenants and agreements of Acquiror contained in
this Agreement shall terminate as of the Effective Time, provided that the
covenants and agreements contained in Sections 6.5, 6.6, 6.7, 6.8 and 9.3 shall
survive the Closing and shall continue in full force and effect.
