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

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.  At the Effective Time, all then

     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 and of Target Options, deposit in escrow
certificates and/or Target Options representing a total of 68,210 shares of
Acquiror Common Stock and/or rights to acquire shares of Acquiror Common Stock,
as the case may be.  Such shares and options shall be held in escrow on behalf
of the persons who are the holders of Target Common Stock and/or Target Options
immediately prior to the Effective Time (collectively, the "FORMER TARGET
STOCKHOLDERS"), on a pro rata basis, in accordance with each such Former Target
Stockholders' percentage ownership ("PRO RATA PORTION") of Target Common Stock
(or rights to acquire shares of Target Common Stock upon the exercise of Target
Options) immediately prior to the Effective Time.  Such shares and options
(together, the "ESCROW SHARES") shall be held as security for the Former Target
Stockholders' indemnification obligations under Article X and pursuant to the
provisions of an escrow agreement (the "ESCROW AGREEMENT") to be executed
pursuant to Section 7.5.

     Section 2.3    DISSENTING SHARES.

               (a)  Notwithstanding any provision of this Agreement to the
contrary, any shares of Target Common Stock held by a holder who has exercised
such holder's dissenter's rights in accordance with Section 262 of Delaware Law
and who, as of the Effective Time, has not effectively withdrawn or lost such
dissenter's 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 who demands his dissenter's 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) and
2.6, 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 dissenter's 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 dissenter's rights with respect to Target Common
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 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 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 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 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 dissenter's rights under Delaware Law and Section
2.3, have no other rights.  Subject to dissenter's rights under Delaware Law and
Section 2.3, from and after the Effective Time, the holders of shares of Target
Common 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 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 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 or Target shall be
liable to a holder of shares of Target Common Stock for shares of Acquiror
Common Stock issuable to such holder pursuant to the provisions of Article II of
the 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 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 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 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 $104.66 (the "REFERENCE STOCK
PRICE").

     Section 2.7    TAX CONSEQUENCES.  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.

agreement previously provided to Acquiror or its representatives.  Except as
contemplated by this Agreement, no option will by its terms require an

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 Date to exercise any
right or benefit held by Target prior to the Effective Time with respect to any

repurchase an optionee's unvested shares on termination of such optionee's
employment.  The assumption by Acquiror of Target Options in accordance with

any obligation or loss of any benefit) under any of the terms, conditions or
provisions of any note, bond, mortgage, indenture, lease, contract or other
agreement, instrument or obligation to which Target is a party or by which it or

defaults, terminations, cancellations or accelerations which would not have a
Material Adverse Effect on Target.

registration, declaration or filing with, any court, administrative agency or
commission or other governmental authority or instrumentality ("GOVERNMENTAL

Recent Balance Sheet or liens that are otherwise permitted by Section 3.7.
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
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.

by a government or taxing authority, nor is any such audit in process, pending
or, to Target's knowledge, threatened (either in writing or verbally, formally
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 asserted or threatened (either in writing or verbally, formally or
informally) 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

Target has not entered into any compensatory agreements with respect to the
performance of services which payment thereunder would result in a nondeductible
expense to Target pursuant to Section 280G of the Code or an excise tax to the
recipient of such payment pursuant to Section 4999 of the Code.  Target has not
agreed to, nor is it required to make any adjustment under Code Section 481(a)
by reason of, a change in accounting method.  Target is not, nor has it been, a
"reporting corporation" subject to the information reporting and record
maintenance requirements of Section 6038A and the regulations thereunder.
Target is in compliance with the terms and conditions of any applicable tax
exemptions, agreements or orders of any foreign government to which it may be
subject or which it may have claimed, and the transactions contemplated by this
Agreement will not have any adverse effect on such compliance.

     Section 3.6    ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as set forth
in the Target Disclosure Schedule, since December 31, 1997, Target has not:

               (a)  suffered any material adverse change in its business, as

     Section 3.7    TITLE AND RELATED MATTERS.  Target has good and marketable
title to all the properties, interests in properties and assets, real and
personal, used in or necessary for the operation of the business of Target, free
and clear of all mortgages, liens, pledges, charges or encumbrances of any kind
or character, except (i) the lien of current taxes not yet due and payable,
(ii) such imperfections of title and encumbrances, if any, that are not material
in character, amount or extent and that do not materially detract from the value
or materially interfere with the present use of the property subject thereto or
affected thereby and (iii) the security interest granted to the holders of the
Target Convertible Notes, which security interest


                                         -14-
<PAGE>

shall be released at or prior to the Effective Time.  The equipment of Target
used in the operation of its business is, taken as a whole, (i) adequate for the
business conducted by Target and (ii) in good operating condition and repair,
ordinary wear and tear excepted.  All real or personal property leases to which
Target is a party are valid, binding, enforceable and effective in accordance
with their respective terms.  To the knowledge of Target, there is not under any
of such leases any existing default or event of default or event which, with
notice or lapse of time or both, would constitute a default.  The Target
Disclosure Schedule contains a description of all personal property with an
individual net book value in excess of $6,000 as of April 30, 1998 and real
property leased or owned by Target as of such date, 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 has the right to use, or is licensed to use, all patents, patent
rights, copyrights, technology, software, software tools, know-how, processes,
inventions, ideas, algorithms, trade secrets, trademarks, service marks, trade
names, Internet domain names and other proprietary rights used in or necessary
for the conduct of Target's business as conducted to the date of this Agreement
and proposed by Target to be conducted, 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
or any product or technology which has been or is being distributed, licensed,
used or sold by Target or currently is under development by Target
(collectively, including such Web site, the "TARGET PRODUCTS"), free and clear
of all liens, claims and encumbrances (including without limitation linking,
licensing and distribution rights) (all of which are referred to as "TARGET
PROPRIETARY RIGHTS").  The Target Products, including all software used in
connection with Target's Web-based services, are free from material defects and
perform in substantial accordance with all published specifications.  In
addition, Target is not aware of any legal restrictions or impediments that
would prevent Target from incorporating those features identified on Schedule
3.8(a) of the Target Disclosure Schedule into a release version of the product.
The Target Disclosure Schedule contains an accurate and complete (i) description
of all patents and patent applications, 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 registrations
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
patents, patent rights, copyrights, trade secrets, software, inventions, ideas,
algorithms, technology, know-how, processes or other proprietary rights that
Target is licensed or otherwise authorized by such third parties to license,
use, market, distribute or incorporate in Target Products (such patents, patent
rights, copyrights, trade secrets, software, inventions, ideas, algorithms,
technology, know-how, processes or other proprietary rights are collectively
referred to as the "THIRD PARTY TECHNOLOGY"), (iii) list of all licenses and
other agreements with third parties relating to any material information,
compilations, data lists or


                                         -15-
<PAGE>

databases that Target is licensed or otherwise authorized by such third parties
to license, use, market, disseminate distribute or incorporate in Target
Products.  Target represents and warrants that (i) Target has provided to
Acquiror copies of any and all standard forms of click-wrap agreement, merchant
agreement and other customer agreements and copies of any agreements that
materially deviate from such standard form agreements, (ii) all such agreements
with Target customers are valid and binding obligations of the parties to such
agreements, and (iii) Target has complete and accurate records indicating that
all such Target customers have assented to the terms of such agreements and has
provided to Acquiror evidence of such records.  Target has not engaged in any
distribution of any software licensed through Free Software Foundation, Inc. (or
any similar organization) in a manner that would require disclosure to any third
party of software source code developed or modified by Target.  To the knowledge
of Target, all of Target's patents, patent rights, copyrights, trademark, trade
name 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, to its knowledge, threatened against Target (and
Target is not aware of any claims which could 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, license, 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.  To the knowledge of
Target, there is 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, exploitation, licensing and use by
Target of any of the Target Products.  None of the Target Products nor the
license and 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, patent right, 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; PROVIDED, HOWEVER, that the foregoing
representation as to the license, use or exploitation by Target of any of the
Third Party Technology licensed to Target under the Third Party Licenses
identified in Section 3.8(a) of the Target Disclosure Schedule is made to the
knowledge of Target only.

               (b)  Except as set forth in the Target Disclosure Schedule,
Target has not granted any third party any right to manufacture, reproduce,
license, use, distribute or market any of the Target Products or any
adaptations, translations, or derivative works based on the Target Products or
any portion thereof.

               (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


                                         -16-
<PAGE>

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 the applicable 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.
               (d)  To Target's knowledge, 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.  To the knowledge of Target, such confidentiality and
non-disclosure agreements constitute valid and binding obligations of Target and
such person, enforceable in accordance with their respective terms.

               (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.

               (h)  All use, disclosure or appropriation of confidential
information not otherwise protected by patents, patent applications or copyright
("CONFIDENTIAL INFORMATION") owned by Target by or to a third party as
applicable has been pursuant to the terms of a written agreement between Target
and such third party.  All use, disclosure or appropriation of Confidential
Information not owned by Target has been made pursuant to the terms of a written
agreement between Target and the owner of such Confidential Information, or is
otherwise lawful.

     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


                                         -17-
<PAGE>

material employee benefit plans (as defined in Section 3(3) of the Employee
Retirement Income Security 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 or made available to Acquiror or its
representatives a copy of each of the Target Employee Plans which have been
reduced to writing, a summary of any unwritten plan 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 except as
required by applicable law; (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; which could reasonably be expected to have,
in the aggregate, a Material Adverse Effect on Target, (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), except as would not have, in the
aggregate, a Material Adverse Effect on Target, 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


                                         -18-
<PAGE>

any material 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
material 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 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 except as would not give rise, in
the aggregate, to a Material Adverse Effect on Target.  No suit, administrative
proceeding, action or other litigation has been brought, or to the best
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 and (ii) the applicable requirements of the
Family Leave Act of 1993 and the regulations thereunder, except with respect to
both clauses (i) and (ii) to the extent that such failure to comply would not,
in the aggregate, have a Material Adverse Effect on Target.

               (e)  Except as set forth in the Target Disclosure Schedule, 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.

arrangement) in excess of $15,000 over the term of such agreement, contract or
commitment.

                    (iv)   Target has no outstanding sales or advertising
contract, commitment or proposal (including, without limitation, insertion
orders, slotting agreements or other agreements under which Target has allowed
third parties to advertise on or otherwise be included in Target's World Wide
Web sites) that Target currently expects to result in any loss to Target in
excess of $15,000 upon completion or performance thereof.

                    (v)    Target has no currently effective collective
bargaining or union agreements, contracts or commitments.

                    (viii) Target has no outstanding loan or advance to any
person; nor is it party to any line of credit, standby financing, revolving
credit or other similar financing arrangement of any sort which would permit the
borrowing by Target of any sum.

                    (ix)   Target has no agreements pursuant to which Target
has agreed to manufacture for, supply to or distribute to any third party any

have been provided to Acquiror or its representatives.

               (b)  All of the Material Contracts listed on the Target
Disclosure Schedule are valid, binding, in full force and effect, and
enforceable by Target in accordance with their respective terms. No Material
Contract contains any liquidated damages, penalty or similar provision.  To the
knowledge of 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 material default under or in material
breach or violation of, nor, to Target's knowledge, is there any valid basis for
any claim of material default by Target under, or material breach or violation
by Target 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.  No claims have been made or threatened that would require

meeting (the "TARGET STOCKHOLDERS' MEETING") for the purpose of seeking,
approval of this Agreement, the Merger and related matters.  If Target holds a
stockholders' meeting, the Board of Directors will solicit proxies from Target's
stockholders to vote such stockholders' shares at the Target Stockholders'
Meeting.  In soliciting such written consent or proxies, the Board of Directors
of Target will recommend to the stockholders of Target that they approve this
Agreement and the Merger and shall use its reasonable efforts to obtain the

Agreement and the Merger in accordance with Delaware Law and Target's
Certificate of Incorporation.  Target will prepare as soon as reasonably
practicable the Information Statement in form and substance reasonably
acceptable to Acquiror, with respect to the solicitation of written consents
and/or proxies from the stockholders of Target to approve this Agreement, the
Merger and related matters.  The Information Statement shall be in such form and
contain such information so as to permit compliance by Acquiror with the
requirements of Section 4(2) and/or Regulation D under the Securities Act in
connection with the issuance of shares of Acquiror Common Stock in the Merger
and will comply in all material respects with all applicable requirements of law
and the rules and regulations promulgated thereunder.  Within

the Information Statement to the stockholders of Target. Whenever any event
occurs which is required to be set forth in an amendment or supplement to the
Information Statement, Target will promptly inform the Acquiror of such
occurrence and cooperate in making any appropriate amendment or supplement,
and/or mailing to stockholders of Target, such amendment or supplement.  The
Information Statement will include the recommendation of the Board of Directors
of Target in favor of adoption and approval of this Agreement and approval of
the Merger.

     Section 5.2    ADVICE OF CHANGES.  Target will promptly advise Acquiror in
writing of any event occurring subsequent to the date of this Agreement which
would render any representation or warranty of Target 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 5.3    OPERATION OF BUSINESS.  During the period from the date of

disputes over such debts or taxes, to pay or perform other obligations when due,
and, to the extent consistent with such business, use all reasonable efforts
consistent with past practices and policies to preserve intact its present

date of this Agreement); or

               (v)  Take, or agree in writing or otherwise to take, any of the
actions described in Sections (a) through (u) above, or any action which is
reasonably likely to make any of Target's representations or warranties
contained in this Agreement untrue or incorrect in any material respect on the
date made (to the extent so limited) or as of the Effective Time.

     In the event that the Closing Date shall not occur on or before June 12,
1998, Acquiror agrees that it will consider in good faith reasonable increases
in or deviations from the limitations set forth in this Section 5.3 in order to
permit the business of Target to continue in its ordinary course consistent with
past practice, and specifically will agree to modifications to subsection (h) to
permit the issuance of Target Convertible Notes in a principal amount not to

                                         -33-
<PAGE>

condition.  Until the Closing, Target shall cause its accountants to cooperate
with Acquiror and its agents in making available all financial information
requested, including without limitation the right to examine all working papers
pertaining to all financial statements prepared or audited by such accountants.
No information or knowledge obtained in any investigation pursuant to this
Section shall effect or be deemed to modify any representation or warranty
contained in this Agreement or its exhibits and schedules.  All such access
shall be subject to the terms of the Confidentiality Agreement (as defined in
Section 7.1).

     Section 5.5    SATISFACTION OF CONDITIONS PRECEDENT.  Target will use its
best efforts to satisfy or cause to be satisfied all the conditions precedent
which are set forth in Sections 8.1 and 8.2, and Target will use its 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 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.  Target will not, directly or
indirectly, through any of its officers, directors, employees, agents and
Affiliates 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

     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, including shares of Acquiror Common Stock that will
be issued upon exercise of Target Options assumed by Acquiror.

     Section 6.3    SATISFACTION OF CONDITIONS PRECEDENT.  Acquiror and Sub will
use their 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 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, including shares of Acquiror Common Stock issuable upon exercise of
Acquiror Options, to be authorized for listing on the Nasdaq National Market.

     Section 6.5    STOCK OPTIONS.

               (a)  At the Effective Time, each outstanding Target Option under
the Target Option Plan or otherwise, 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.  The term, exercisability, vesting schedule, acceleration
events, status as an "incentive stock option" under Section 422 of the Code, if
applicable, and all of the other terms of the option shall otherwise remain
unchanged.


                                         -35-
<PAGE>

               (b)  As soon as practicable after the Effective Time, Acquiror
shall deliver to the participants in the Target Option Plan and other option
holders appropriate notice setting forth such participants' rights pursuant
thereto and stating that the grants pursuant to the Target Option Plan or
otherwise 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 on or prior to the Effective Time 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.  Acquiror shall use its best efforts to file a
registration statement on Form S-8 (or any successor or other appropriate forms
that Acquiror is eligible to use) under the Securities Act or another
appropriate form with respect to the shares of Acquiror Common Stock subject to
such options within two (2) business days following the Closing Date 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.

     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, but excluding shares of
Acquiror Common Stock issued in the Merger 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")
and excluding shares of Acquiror Common Stock issuable upon exercise of Target
Options (the issuance of which will be registered on Form S-8); 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 Holders for the purposes of this Section 6.6.

               (b)  REQUIRED REGISTRATION.  Acquiror shall use its best efforts
to prepare and file with the Commission a registration statement on Form S-3 (or
such successor or other appropriate form that Acquiror is eligible to use) under
the Securities Act with respect to the Registrable Shares (the "Registration
Statement") within two (2) business days following the Closing Date  and to
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)


                                         -36-
<PAGE>

as any selling Holder may reasonably request and that would permit or facilitate
the sale of 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), in each case
so that such Registration Statement and all other such registrations,
qualifications and compliances may become effective no later than 10 days after
the Closing Date, or as soon as practicable thereafter in the event such
Registration Statement becomes subject to review by the Commission Staff.  The
Acquiror does not have any knowledge of any reason, event or state of facts
which would prevent it from filing such Registration Statement within two (2)
business days after the Closing Date or which would prevent the Commission from
declaring such Registration Statement effective in the ordinary course
thereafter.

               (c)  EFFECTIVENESS.

                    (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 the later to occur of (A) one (1) year
from the Closing Date or (B) such time as each Holder shall be permitted to sell
all of the remaining Registrable Shares in one three-month period under Rule 144
or (C) such time as all of the Registrable Shares shall have been sold or
otherwise disposed of by the Holders (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 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.

                    (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
stockholders 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 (the "SUSPENSION PERIOD").  Acquiror will use all reasonable efforts to
minimize the length of the Suspension Period and cause the termination of the
Suspension Period to occur as quickly as reasonably practicable.  The parties
agree that the one-year component of the Registration Effective Period
contemplated by subparagraph (c)(i)(A) above shall be extended for a period of
time equal to the Suspension Period, PROVIDED that in no case will the one-year
component be extended to a date later than 18 months following the Closing Date
and PROVIDED FURTHER that in no event will the Registration Effective Period be
extended for any reason beyond the time at which each Holder


                                         -37-
<PAGE>

shall be permitted to sell all of such Holder's remaining Registrable Shares in
one three-month period under Rule 144.

               (d)  EXPENSES.  The Acquiror shall bear all costs and expenses
for purposes of complying with this Section 6.6 including, 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, 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 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


                                         -38-
<PAGE>

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 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


                                         -39-
<PAGE>

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.

               (f)  CURRENT PUBLIC INFORMATION.  Until the earlier of the second
anniversary of the Closing Date (or, if any Holder is an affiliate of Acquiror,
the third anniversary of the Closing Date) or the date all shares of Acquiror
Common Stock subject to this Section 6.6 have been sold, Acquiror will timely
file all reports required to be filed by it under the Exchange Act, and the
rules and regulations adopted by the Commission thereunder, all to the extent
required to enable such Holders to sell their shares pursuant to Rule 144 and
the Registration Statement.  Upon written request, Acquiror will deliver to such
holders a written statement as to whether it has compiled with such
requirements.

     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 refuse to permit the Holder to resell any
Registrable Shares pursuant to the Registration Statement; provided, however,
that in order to exercise this right, Acquiror must deliver a certificate in
writing to the Holder to the effect that a delay in such sale is necessary
because a sale pursuant to the Registration Statement in its then-current form
without the addition of material, non-public information about Acquiror, could
constitute a violation of the federal securities laws.  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 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.


                                         -40-
<PAGE>

               (c)  COPIES OF PROSPECTUSES.  Subject to the provisions of this
Section 6.7, when a Holder entitled to sell gives notice of its intent to sell
Registrable Shares pursuant to the Registration Statement, Acquiror shall,
within two (2) trading days following a request from such Holder, 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.  All Target Options assumed by Acquiror at
the Effective Time pursuant to the terms of Section 6.5(a) shall remain
outstanding following the Effective on the same terms and conditions as prior to
the Effective Time, subject to the adjustments contemplated by such Section 6.5.
Employees of Target as of the Effective Time shall be permitted to participate
in the 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    INDEMNIFICATION.  The Acquiror shall not, for a period of
six years after the Effective Time, take any action to alter or impair any
exculpatory or indemnification provisions now existing in the Certificate of
Incorporation or By-laws of Target for the benefit of any individual who served
as a director or officer of Target at any time prior to the Effective Time,
except for any changes which may be required to conform with changes in
applicable law and any changes which do not affect the application of such
provisions to acts or omissions of such individuals prior to the Effective Time.

     Section 6.10   TAX TREATMENT.  Acquiror and its Subsidiaries will not take,
or cause Target to take, any action after the Effective Time which reasonably
could be expected to cause the Merger to fail to qualify as a reorganization
under the provisions of Section 368(a) of the Code.

                                     ARTICLE VII

Acquiror with a properly executed Foreign Investment and Real Property Tax Act
of 1980 ("FIRPTA") FIRPTA Notification Letter which states that shares of
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 1.1445-2(c)(3).  In
addition, simultaneously with delivery of such FIRPTA Notification Letter,
Target shall provide to Acquiror, as agent for Target, a form of notice to the
Internal Revenue Service in accordance with the requirements of Treasury
Regulation Section 1.897-2(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 7.7    BLUE SKY LAWS.  Acquiror shall take such steps as may be
necessary to comply with the securities and blue sky laws of all jurisdictions

               (b)  by either Acquiror or Target, by giving written notice to
the other party, if a court of competent jurisdiction or other Governmental

               (c)  by Acquiror or Target, by giving written notice to the other

party;

               (d)  by Acquiror, by giving written notice to Target, if the
Closing shall not have occurred on or before June 26, 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

     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 $150,000
(excluding fees payable to Broadview Associates, which amount is set forth on
Schedule 9.3(b) hereto and which shall be paid by the Acquiror) and shall be
borne by the stockholders of Target to such extent and will not become
obligations of Target.  Except as otherwise contemplated by Section 8.3(d),
Target will make arrangements for the payments of such fees acceptable to
Acquiror.  Any such fees and expenses in excess of $150,000 incurred by Target
shall be recoverable from the Escrow Fund (as defined in Section 10.2) as
Damages (as defined in Section 10.1) without regard to the damage threshold as
contemplated by Section 10.3.  The payment by Acquiror of certain of such fees
in the manner contemplated by Section 8.3(d) shall in no way increase or
otherwise affect the $150,000 expense limitation provided for in this Section.

                                      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).  Such indemnification shall be the
Acquiror's sole and exclusive remedy for any such breach by Target, except for
cases fraud on the part of Target.  Acquiror acknowledges that, with respect to
the evaluation of  the Target Financial Statements for purposes of making any
claim under this Section 10.1 for a breach of the representations set forth in
Section 3.4(b), Acquiror and its independent public accountants, Price
Waterhouse, have had the opportunity to review Target's accounting policies and
methods and underlying assumptions inherent in the Target Financial Statements
and, accordingly, Acquiror shall be required to consistently apply the
accounting policies, methods and assumptions in the audited Target Financial
Statements.

     Section 10.2   ESCROW FUND.  As security for the indemnities in Section
10.1, as soon as practicable after the Effective Date, the Escrow Shares shall
be deposited with Chase Trust


                                         -47-
<PAGE>

Company of California (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, the indemnification obligations of each Former Target Stockholder
pursuant to this Article X shall be limited to the amount and assets deposited
by such Former Target Stockholder 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 any Former Target Stockholder 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 (except for
cases involving fraud on the part of Target).

     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 $125,000 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 $125,000 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.

     Section 10.4   ESCROW PERIODS.  The Escrow Fund shall commence on the
Closing Date and terminate eighteen (18) months from the Closing Date (the
period from the Closing 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 (as
defined in Section 10.8) 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"):

                    (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, 10.7 and 10.8 hereof, 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


                                         -48-
<PAGE>

the Holders (as defined in the Escrow Agreement) based upon their respective
percentage interests therein at the time in the form (Acquiror Common Stock or
options  to acquire Acquiror Common Stock or cash) contributed by each such
Holder.

     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
shall be the Reference Stock Price.

     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 10.5, 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 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 10.8, 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.

     Section 10.9   STOCKHOLDERS' AGENTS.

               (a)  Omar Khudari and Alan Docter 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
in the exercise of reasonable judgment, 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.

               (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


                                         -50-
<PAGE>

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 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 to settle any such claim; PROVIDED,
HOWEVER, that Acquiror may not affect 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, unless such claim is in an amount in excess of
any amount consented to by the Stockholders' Agents.

                                      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 and 9.3
and Article X shall survive the Closing and shall continue in full force and
effect.

     Section 11.2   NOTICES.  All notices and other communications hereunder
