                          BANYAN SYSTEMS INCORPORATED
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A.   BASIS OF PRESENTATION:

     The accompanying unaudited consolidated financial statements include the
     accounts of Banyan Systems Incorporated ("Banyan Worldwide") and its
     subsidiaries as of June 30, 1999, and have been prepared by the Company in
     accordance with generally accepted accounting principles. In the opinion of
     management, the accompanying unaudited consolidated financial statements
     contain all adjustments, consisting only of those of a normal recurring
     nature, necessary for a fair presentation of the Company's financial
     position, results of operations and cash flows at the dates and for the
     periods indicated. While the Company believes that the disclosures
     presented are adequate to make the information not misleading, these
     consolidated financial statements should be read in conjunction with the
     consolidated financial statements and related notes included in the
     Company's 1998 Annual Report to Stockholders and Annual Report on
     Form 10-K.

     The results of operations for the three-month period ended June 30, 1999
     are not necessarily indicative of the results expected for the full fiscal
     year or any future interim period.

B.   REPORTABLE SEGMENTS:

     Banyan Systems Incorporated has two reportable segments: Network software
     and services, and Internet advertising. The Company's network software and
     services segment designs, develops and markets standards-based networking
     directory and messaging solutions that help people communicate across
     enterprise networks, intranets and the Internet. In addition, the network
     software and services segment delivers professional services including
     technical support, education and consulting, including network performance,
     integration and Year 2000 compliance services. The Company's Internet
     advertising segment is organized as a majority-owned subsidiary,
     Switchboard Incorporated, and generates advertising revenue from major
     domestic corporations and local businesses through its Internet people-to-
     people and business directory services. The Company's reportable segments
     are managed separately because they market and distribute distinct products
     and services.

C.   BASIC AND DILUTED EARNINGS PER SHARE:

     Basic earnings per share is based upon the weighted average number of
     common shares outstanding during the period. Diluted earnings per share
     includes the dilutive effect of potential common stock outstanding during
     the period. Potential common stock results from the assumed exercise of
     outstanding stock options and warrants, the proceeds of which are then
     assumed to have been used to repurchase outstanding common stock shares
     using the treasury stock method, and the conversion of preferred stock
     using the "if-converted" method. The following table reconciles the
     numerator and denominator of the basic and diluted earnings per share
     computations shown on the Consolidated Statements of Operations:

     Options and warrants to purchase 98,000 shares of common stock outstanding
     during the three-months and six-months ended June 30, 1999, were excluded
     from the calculation of diluted net income per share because the exercise
     price of those options and warrants exceeded the average market price of
     the Company's common stock during the respective periods.  Options and
     warrants to purchase 2,629,000 shares of outstanding common stock during
     both the three-months and six-months ended June 30, 1998 were excluded from
     the calculation of diluted net loss per share as the effect of their
     inclusion would have been anti-dilutive.

D.   COMPREHENSIVE INCOME

     Other comprehensive income includes unrealized gains or losses on the
     Company's available-for-sale investments and foreign currency translation
     adjustments.

E.   SALE OF INVESTMENT

     In 1996, the Company made an equity investment of approximately $2,001,000
     in Software.com, a company which supplies Internet messaging solutions to
     service providers (ISPs, telcos, cable companies, and Web portals). In the
     second quarter of 1999, as part of Software.com's initial public offering,
     the Company sold 339,985 shares of common stock of Software.com resulting
     in net proceeds of $4,743,000 and a realized net gain of approximately
     $4,043,000.  Additionally, the Company held 1,021,202 shares of common
     stock of Software.com at June 30, 1999 which were valued at $23.188 per
     share, with a total value of $23,680,000. The net unrealized gain of
     approximately $22,200,000 is included in other comprehensive income within
     stockholders' equity. These remaining shares of common stock of
     Software.com held by the Company are subject to a six-month trading
     restriction which ends in December 1999.

F.   CBS PARTNERSHIP

     On June 30, 1999, the Company and CBS consummated their agreement for CBS
     to acquire a 35% equity stake in Switchboard. In exchange, Switchboard
     received $5,000,000 in cash and will receive promotion and branding over
     terms of seven and ten years, respectively, across the full range of CBS
     media properties, as well as those of its radio and outdoor subsidiary,
     Infinity Broadcasting Corporation. CBS, the Company and Switchboard
     Incorporated entered into an Advertising and Promotion Agreement dated as
     of June 30, 1999, which provides advertising to Switchboard over seven
     years as part of payment for common stock and warrants provided by CBS
     under the Common Stock and Warrant Purchase Agreement by and among
     Switchboard Incorporated, the Company and CBS. The net present value of the
     advertising has been recorded as a subscription receivable and an
     offsetting amount as paid in capital in the Switchboard equity accounts.
     The subscription equity account will be amortized as marketing expense over
     the advertising period. The objectives of the Advertising and Promotion
     Agreement include (i) the

                                     - 8 -
<PAGE>

     promotion through CBS of the Switchboard site to be accessed via the domain
     name www.cbs.switchboard.com or www.switchboard.com; (ii) the establishment
          -----------------------    -------------------
     of co-branded interfaces between CBS sites and the Switchboard site; (iii)
     the development of vertical guides for CBS sites and CBS associated sites
     and (iv) the utilization of CBS's cross-media sales group, CBS PLUS, in
     selling Switchboard advertisements and e-commerce services. Switchboard
     will be required to pay CBS a commission on the net advertising revenues
     derived from the sale of advertising on the co-branded interfaces or
     vertical guides during the term of the agreement. CBS received warrants to
     purchase an additional 5% of Switchboard at a per share exercise price of
     $1.00, which would increase its ownership position in the subsidiary to
     40%. The warrants are not exercisable by CBS until the earlier of (i) June
     30, 2001 or (ii) the closing of an initial public offering of Switchboard's
     common stock. CBS and Switchboard Incorporated entered into a License
     Agreement dated as of June 30, 1999 which provides a ten year license to
     Switchboard for the utilization of the CBS Marks in achieving the
     objectives of the Advertising and Promotion Agreement. Two representatives
     of CBS will join Switchboard's Board of Directors. Additionally, the
     Company issued a common stock purchase warrant to CBS on June 30, 1999,
     whereby CBS received warrants to purchase 250,000 shares of the Company's
     common stock at $11.17 per share.

                             RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

GENERAL

Total revenues for the three-month period ended June 30, 1999 were
$19.3 million, which represented a 6% increase when compared to the
corresponding period in 1998. Total revenues for the six-month period ended June
30, 1999 were $38.3 million, which represented a 7% increase when compared to
the corresponding period in 1998. These increases were due to incremental
revenues from services and Internet advertising offset in part by a decrease in
software revenues. The Company's software revenues for the three-month period
ended June 30, 1999 decreased by $3.5 million, or 33%, when compared to the
corresponding period in 1998. The Company's software revenues in the six-month
period ended June 30, 1999, decreased by $7.0 million, or 31%, when compared to
the corresponding period in 1998. The decline in software revenues in 1999 was
attributable primarily to lower levels of sales of the Company's VINES and
messaging products, primarily as a result of competitive product offerings. The
Company expects that software revenues will continue to decline for the
foreseeable future. Services revenues increased by $4.4 million, or 77%, and
$8.6 million, or 81%, for the three-month and six-month periods ended June 30,
1999, when compared to the corresponding periods in 1998. The increase in
services revenues in 1999 was attributable primarily to additional revenues
generated from consulting services and technical support services. Internet
advertising revenues increased by $0.3 million, or 18%, and $0.8 million, or 30%
for the three and six month periods ended June 30, 1999 when compared to the
corresponding periods in 1998. The increase in Internet advertising revenues in
1999 was due to an increase in third-party license fees for directory services
and local advertising revenues generated by the Company's majority-owned
subsidiary, Switchboard Incorporated's ("Switchboard") Web site. The increase
was partially offset by declines in national advertising revenues as a result of
the termination of Switchboard's marketing relationship with AOL.

International revenues for the three-month and six-month periods ended June 30,
1999 were $6.6 million and $12.3 million, respectively, compared with
$5.7 million and $11.2 million for the corresponding periods in 1998.
The increases for both the three-month and six-month periods ended June 30, 1999
were primarily due to additional revenues from consulting services offset in
part by a decline in software revenues. International revenues accounted for 34%
and 32% for the three and six month periods ended June 30, 1999, compared with
32% and 31% for the corresponding periods in 1998.

Gross profits for software were 85%, or $6.2 million, and 84%, or $13.0 million,
for the three-month and six-month periods ended June 30, 1999, respectively,
compared with 88%, or $9.5 million, and 88%, or $19.9 million, for the
corresponding periods in 1998. The decrease in both gross profit dollars and
percentage for the three-month and six-month periods ended June 30, 1999 when
compared to the corresponding periods last year was primarily due to the impact
of lower sales volumes being spread over fixed costs and a higher mix of lower
margin third-party product sales.

Gross profits for services were 31%, or $3.1 million, and 33%, or $6.2 million,
for the three-month and six-month periods ended June 30, 1999, respectively,
compared with 36%, or $2.0 million,

                                     - 10 -
<PAGE>

and 36%, or $3.9 million, for the corresponding periods in 1998. The increase in
gross profit dollars was primarily due to an increase in revenues from
consulting services and technical support, offset in part by an increase in
delivery personnel and related costs to expand consulting services. The decrease
in gross profit percentage was primarily due to the hiring of additional
delivery personnel and related costs to expand consulting services.

Gross profits for Internet advertising were 84% or $1.7 million, and 81%, or
$2.9 million for the three-month and six-month periods ended June 30, 1999,
respectively, compared with 67%, or $1.2 million and 63%, or $1.8 million, for
the corresponding periods in 1998.  The increase in gross dollars and percentage
was due to an increase in revenues.

Sales and marketing expenses of $6.5 million and $12.8 million for the three-
month and six-month periods ended June 30, 1999, respectively, represented
decreases of 15% and 19% compared to the corresponding periods in 1998.  The
decreases were primarily due to redeployment of staff into the Company's
expanding consulting service activities as well as a cessation of promotional
fees paid to America Online, Inc. ("AOL") under the Company's former marketing
relationship between Switchboard and AOL.  Sales and marketing expenses as a
percentage of revenues were 34% and 33% for the three-month and six-month
periods ended June 30, 1999, as compared to 42% and 44% for the corresponding
periods in 1998.

Product development expenses of $2.3 million and $4.8 million for the three-
month and six-month periods ended June 30, 1999, respectively, represented
decreases of 20% and 16%, respectively, over the corresponding periods in 1998.
These decreases were primarily due to lower headcount committed to the Company's
traditional products and less costs associated with Year 2000 compliance when
compared to the corresponding periods in 1998.  The Company had modified and
tested its current product offerings for Year 2000 compliance issues as of
December 31, 1998.  The Company continues to focus its product development
resources on Internet-related product initiatives, Switchboard technology and
services and enhancing its existing product offerings.  Product development
expenses as a percentage of revenues were approximately 12% and 13% for the
three-month and six-month periods ended June 30, 1999, respectively, as compared
to 16% for both the corresponding periods in 1998. There were no software
development amounts capitalized during the six-month periods ended June 30, 1999
and 1998.

General and administrative expenses of $1.8 million and $3.6 million for the
three-month and six-month periods ended June 30, 1999, respectively, represented
increases of 10% and 16% when compared to the corresponding periods in 1998.
The increases were due primarily to an increase in staffing related to the
Switchboard business segment.  General and administrative expenses as a
percentage of revenues were 9% for both the three-month and six-month periods
ended June 30, 1999, as well as for the corresponding periods in 1998.

On June 24, 1999, the Company sold 339,985 shares of common stock of
Software.com  as part of Software.com's initial public offering.  As a result of
the transaction, the Company recorded a net gain of approximately $4.0 million.

Interest income was $259,000 and $532,000 for the three-month and six-month
periods ended June 30, 1999, respectively, and represented increases of 33% and
54% from the corresponding periods in 1998.  These increases were due to higher
levels of available funds invested in marketable securities.

No tax provision, other than that required for foreign income or foreign
withholding taxes, was recorded for the three-month and six month periods ended
June 30, 1999 and 1998, respectively.

LIQUIDITY AND CAPITAL RESOURCES

Working capital increased from $10.2 million at December 31, 1998 to
$46.2 million June 30, 1999. At June 30, 1999, cash and cash equivalents
combined with marketable securities were $62.6 million, compared with
$22.3 million at December 31, 1998. Cash and cash equivalents increased
$4.8 million resulting in a cash balance of $20.0 million June 30, 1999.
This increase was primarily due to a decrease in accounts receivable of
$6.3 million, $5.9 million in cash received from Microsoft Corporation,
$4.7 million in net proceeds from the sale of an investment, $4.3 million in
cash net of related expenses received from CBS Corporation for an investment in
the Company's Switchboard subsidiary, $2.8 million in proceeds from stock plan
purchases and stock options and other various operating, financing and investing
activities. This was offset in part by $11.8 million in net purchases of
marketable securities, and a $7.6 million decrease in VINES related
deferred revenues.

On June 30, 1999, the Company and CBS consummated their agreement for CBS to
acquire a 35% equity stake in Switchboard.  In exchange, Switchboard received
$5.0 million in cash and will receive $130 million of promotion and branding
over terms of seven and ten years, respectively, across the full range of CBS
media properties, as well as those of its radio and outdoor subsidiary, Infinity
Broadcasting Corporation.  CBS also received warrants to purchase an additional
5% of Switchboard, which would increase its ownership position to 40%.
Two representatives of CBS will join Switchboard's Board of Directors.
Additionally, CBS received warrants to purchase 250,000 shares of the Company's
common stock at $11.27 per share.

In the second quarter of 1999, as part of Software.com's initial public
offering, the Company sold 339,985 shares of Software.com's common stock
resulting in net proceeds of approximately $4.7 million and a realized net gain
of approximately $4.0 million.  Additionally, the Company held 1,021,202 of
Software.com's common stock shares at June 30, 1999 which were marked to market
at $23.188 per share with a total value of $23.7 million.  The net unrealized
gain of $22.2 million is included in other comprehensive income within
stockholder's equity.  The remaining shares of Software.com's common stock held
by the Company are subject to a six-month lock-up period.

On January 11, 1999, the Company announced a strategic alliance with Microsoft.
As part of the agreement, Microsoft has committed to contributing $10.0 million
to the Company over a three-year period to fund the training of at least 500
professionals, marketing and development costs as well as the purchase of a
warrant to purchase 1.75 million shares of the Company's common stock.

                                     - 12 -
<PAGE>

The first of three payments to be made by Microsoft to the Company was received
in January 1999 in the amount of $5.9 million. The remaining two payments
totaling $4.1 million are scheduled to be received on or before December 31,
1999 and 2000.

On September 4, 1997, the Company entered into a $15.0 million line of credit
agreement (the "Credit Agreement") with Foothill Capital Corporation
("Foothill").  In general, the Company's obligations under the Credit Agreement
bear interest at the variable base rate per annum of Norwest Bank Minnesota,
National Association.  The Credit Agreement has a three-year initial term.
Foothill was granted warrants to purchase 75,000 and 50,000 and will be granted
warrants to purchase 25,000 shares of the Company's common stock at the then
current fair market value on September 4, 1997, 1998 and 1999, respectively.
On January 13, 1999, Foothill exercised its warrants to purchase 75,000 shares
of the Company's common stock pursuant to a "cashless" exercise resulting in the
issuance of 58,603 shares to Foothill. On May 14, 1999, Foothill exercised its
warrants to purchase 50,000 shares of the Company's common stock pursuant to a
"cashless" exercise resulting in the issuance of 32,098 shares to Foothill.
There were no amounts outstanding under the line of credit agreement during the
period ended June 30, 1999.

The Company believes that existing cash and marketable securities, combined with
cash expected to be generated from operations and the available line of credit,
will be sufficient to fund the Company's operations through at least the next
twelve months.

FACTORS AFFECTING FUTURE OPERATING RESULTS

Certain of the information contained in this Form 10-Q, including information
with respect to the Company's plans and strategy for its business, statements
relating to the sufficiency of cash and cash equivalent balances, anticipated
expenditures and the intended effects of the Company's restructuring, sales and
marketing, and product development efforts, consists of forward-looking
statements.  Any statements contained herein that are not statements of
historical fact may be deemed to be forward-looking statements.  Without
limiting the foregoing, the words "believes," "expects," "anticipates," "plans,"
and similar expressions are intended to identify forward-looking statements.
Important factors that could cause actual results to differ materially from the
forward-looking statements include the following factors:

In 1998 and the first six months of 1999, a majority of the Company's network
sales were to existing customers for upgrade, expansion of their networks, or
consulting delivery.  The Company's results will depend on its ability both to
continue to sell products for use in networks of existing customers and to
attract new customers for the Company's products and services.  There can be no
assurance that the Company will be successful in its sales and marketing
efforts.  In addition, in 1998 and the first six months of 1999, the Company
experienced extended selling cycles due to competitive products introduced by
other vendors, an increase in multi-year customer agreements and to longer
evaluation of operating systems and hardware platforms by potential customers.
The Company expects that extended selling cycles will continue to affect the
Company's operating results for the foreseeable future.

The Company continues to evolve its strategic focus, seeking to decrease its
reliance on its traditional networking software products while devoting
additional resources to its network services and Internet business initiatives.
On June 21, 1999, the Company announced it will begin doing business under the
new name, "Banyan Worldwide", and that a new division had been formed, Banyan
Worldwide Services, to support the further development of its services
businesses. Banyan Worldwide is organized as Banyan World Wide Services, a
division that provides consulting, systems integration and technical support
services; Switchboard Incorporated, the Company's majority-owned Internet
subsidiary; and Banyan Technology Group, which focuses on the development of
traditional Banyan software products, as well as leading edge Internet
technologies.

As part of its strategic focus on network services, on January 11, 1999, the
Company announced a global alliance with Microsoft to deliver integrated
messaging, networking and Internet solutions and the collaboration on the design
and implementation of packaged services, solutions and support offerings based
on Microsoft's enterprise platform. The agreement contains various obligations
and milestones that must be met by the Company, including the certification of
500 Microsoft-trained professionals. The failure of the Company to meet such
obligations and milestones could result in a termination of the agreement, which
could have a material adverse effect on the Company. In addition, the Company's
future success will depend in part upon its ability to continue to grow its
network services business, acquire additional network services customers and
adapt to changing technologies and customer requirements. Any failure to do so
could have a material adverse effect on the Company. There can be no assurance
the Company will be successful in its new strategic focus.

                                     - 13 -
<PAGE>

The Company's results are partially dependent on its ability to enhance existing
products and introduce new products on a timely basis, and to achieve market
acceptance for such enhanced new products.  The Company has invested significant
resources to develop products and services to bring the Company's directory and
messaging capabilities to Internet users. The Internet market space is
increasingly competitive and rapidly changing.  Any delay in developing
additional or enhanced products and services for the Internet or failure of its
Internet products and services to achieve increase market acceptance could have
a material adverse effect on the Company's future results of operations.
In 1999, the Company entered into agreements with Oblix, Incorporated ("Oblix"),
and Check Point Software Technologies Limited ("Check Point") to resell Oblix
and Check Point products. On May 2, 1999, the Company introduced Worktop, a
browser-based productivity tool that helps organizations maximize the value of
their intranets by providing employees with a highly personalized start page to
organize and monitor key Web-accessible information. Failure of these products
and the Company's other recently released products to achieve market acceptance
could have a material adverse effect on the Company's future results of
operations.

In 1996, the Company, through a majority-owned subsidiary, introduced
Switchboard, a directory service for Internet users.  A substantial percentage
of the traffic on the Switchboard Internet Web site in 1998 was attributable to
the Company's marketing arrangements with AOL, a minority owner of Switchboard
Incorporated. Accordingly, a substantial percentage of Switchboard Internet
advertising revenues in 1998 were dependent on the marketing arrangements with
AOL. In August 1998, the Company announced that the White Pages contract between
Switchboard and AOL would not be renewed at the end of November 1998. On
December 10, 1998, the Company announced that the Yellow Pages contract between
Switchboard and AOL would not be renewed at the end of 1998. The Company
estimates that AOL's customers accounted for approximately 45 percent of its
overall traffic and 30 percent of its total advertising revenues in 1998.
There can be no assurance that termination of these arrangements with AOL will
not have any further material adverse effect on the Company.

In February 1999, Switchboard launched its "local merchant strategy" to
substantially increase its business with local merchants through display
advertising, Web site hosting and other on-line services.  This launch included
strategic partnerships with Discover Financial Services, Comcast Online
Communications, Qwest Communications International, Inc., Cox Interactive Media
and Advance Internet Inc.  In March 1999, Switchboard entered into an agreement
with the At Hand Network Yellow Pages which calls for Switchboard to fulfill the
yellow page searches conducted primarily in the Northeast region of the United
States on the At Hand Network Yellow Pages and provide e-mail address searches
for the entire At Hand Network.  The success of the Company will depend in part
on the success of this and the Company's other strategic alliances and the
Company's ability to enter into new strategic alliances with other Internet
providers.

On June 30, 1999, CBS acquired a 35% equity stake in Switchboard in exchange for
$5.0 million in cash and $130.0 million of promotion and branding to be
delivered over terms of seven and ten years, respectively, across the full range
of CBS media properties, as well as those of its radio and outdoor subsidiary,
Infinity Broadcasting Corporation. CBS also received warrants to purchase an
additional 5% of Switchboard at a per share exercise price of $1.00, which would
increase its ownership position in the subsidiary to 40%. Two representatives of
CBS will join Switchboard's Board of Directors. Additionally, CBS received
warrants to purchase 250,000 shares of the Company's common stock at $11.17 per
share. In connection with CBS' investment in Switchboard, CBS and Switchboard
entered into a license agreement under which CBS licenses the "CBS" trademark
and "Eye" design to Switchboard which include broad restrictions on use and
implementation. Switchboard's failure to effectively utilize these promotional
and branding capabilities could have a material adverse impact on the Company's
future operations. Moreover, a breach by Switchboard of any of its agreements
with CBS could result in the termination of CBS' obligations to provide these

would retain its Switchboard securities.

In the six months ended June 30, 1999, international revenues accounted for 32%
of the Company's total revenues.  The Company's results of operations in 1998
and the first six months of 1999 were adversely affected by the global economic
uncertainty, and in particular, the financial market instability in Asia. There
can be no assurance such uncertainty will not continue to adversely affect the
Company's operating results.

The Company currently owns 1,021,202 shares of Software.com .  The Company is
restricted from trading these shares until December 25, 1999.  Any devaluation
of the market price of Software.com's common stock prior to this date could have
a material adverse effect on the Company's liquidity and capital resources.

See "Year 2000 Readiness Disclosure" below.

EURO CONVERSION DISCLOSURE

On January 1, 1999, the participating member countries of the European Union
adopted the Euro as the common legal currency and fixed conversion rates between
their existing sovereign currencies and the Euro. The Company does not believe
that the Euro conversion will have a material impact on the Company's
operations.

Because of the foregoing factors and the factors incorporated herein by
reference, the Company believes that period-to-period comparisons of its
financial results are not necessarily meaningful and it expects that its results
of operations may fluctuate from period-to-period in the future.

YEAR 2000 READINESS DISCLOSURE

The following statement shall be considered a Year 2000 readiness disclosure to
the maximum extent allowed under the Year 2000 Information and Readiness
Disclosure Act.  This Year 2000 readiness disclosure does not constitute a
warranty of any kind, or extend the terms of any existing warranty.

In the past, many information technology products were designed with two digit
year codes that did not recognize century and millenium fields. As a result,
these hardware and software products may not function or may give incorrect
results beginning in the Year 2000. In order to address this issue, such
hardware and software products may need to be upgraded or replaced in order to
correctly process dates beginning in the Year 2000.

The Company has created a Company-wide Year 2000 team to identify and address
Year 2000 issues. The Company's Year 2000 compliance program has identified
three potential areas of impact for review: (i) the software, information and
non-information systems used in the Company's internal business systems; (ii)
the Company's software offered to customers; and (iii) third-party vendors,
manufacturers and suppliers of products used in the Company's internal systems
or distributed with the Company's products. The Company has identified and is
testing its main internal systems and expects to complete testing by September
30, 1999.  Currently, the testing is approximately 90% complete.  During 1999,
the Company expects to complete implementation of any needed Year 2000-related
modifications to its critical information systems.

                                     - 15 -
<PAGE>

The Company has completed a process of communicating with its main suppliers of
technology products and services used in its internal systems regarding the
Year 2000 status of such products or services. Based upon these communications,
the Company has considered the suppliers' Year 2000 preparedness in the
Company's decision to continue to deploy or migrate from these technology
products or services. In addition, the Company has assessed its internal non-
information technology systems, and expects to complete testing and any needed
modifications to these systems by September 30, 1999. To date, the Company has
not developed a comprehensive contingency plan to address situations that may
result if the Company is unable to achieve Year 2000 readiness of its critical
operations. By September 30, 1999, the Company expects to finalize its
assessment of and, if deemed appropriate, contingency planning for potential
operational or performance problems related to Year 2000-related issues with its
information systems.

The Company's total cost relating to these activities has not been and is not
expected to be material to the Company's financial position, results of
operations, or cash flows. The Company's current assessment is that the cost of
completing the Company's Year 2000 compliance program will be approximately
$250,000, which does not include amounts related to the diversion of internal
resources including, without limitation, employee salaries, which amount the
Company is not separately tracking. The Company has and expects to continue to
fund its Year 2000 compliance program from operating cash flows and does not
expect to separately account for these costs.  There can be no assurance that
there will not be a delay in, or increased costs associated with, the
implementation of any necessary modifications, or that the Company's suppliers
will adequately prepare for the Year 2000 issue.  It is possible that any such
delays, increased costs, or supplier failures could have a material adverse
impact on the Company's operations and financial results, by, for example,
impacting the Company's ability to deliver products or services to its
customers.

The Company's Year 2000 effort has included testing products currently or
recently on the Company's price list for Year 2000 issues. Products have been
and are expected to continue to be tested internally. Generally, for products
that were identified as needing updates to address Year 2000 issues, the Company
has prepared or is preparing updates, or has discontinued or will discontinue
the product.  Currently, this testing is approximately 99% complete. Some of the
Company's customers are using product versions that the Company will not support
for Year 2000 issues.  The Company has completed a process of notification to
its customers of these Year 2000 issues and has encouraged these customers to
migrate to current product versions that are Year 2000 ready. There can be no
assurance the Company will be successful in migrating these customers to the
Year 2000-compliant products of the Company. For third-party products that the
Company distributes with its products, the Company has sought information from
the product manufacturers regarding the products' Year 2000 readiness status.
Customers who use the third-party products are directed to the product
manufacturer for Year 2000 status information. On its Year 2000 Web site at
www.banyan.com, the Company provides information regarding which of its products
have been tested to be Year 2000 ready and other general information related to
the Company's Year 2000 efforts. The Company's total costs relating to these
activities has not been and is not expected to be material to the Company's
financial position or results of operations.

The Company believes its current products, with any applicable updates, are
Year 2000 ready when used in a system and with other components that are
Year 2000 compliant. However, there can be no guarantee that one or more of the
Company's products do not contain Year 2000 date issues. The most reasonably
likely worst case scenarios would include (i) corruption of data contained in
the Company's information systems, (ii) hardware failure and (iii) the failure
of infrastructure services provided by third parties (e.g. electricity, phone
service, etc.)

                                     - 16 -

Because the Company is in the business of selling software products, the
Company's risk of being subjected to lawsuits relating to Year 2000 issues with
its software products is likely to be greater than that of companies in other
industries.  Because computer systems may involve different hardware, firmware
and software components from different manufacturers, it may be difficult to
determine which component in a computer system may cause a Year 2000 issue. As a
result, the Company may be subjected to Year 2000-related lawsuits independent
of whether its products and services are Year 2000 ready. The outcome of any
such lawsuit and the impact on the Company cannot be predicted. Any Year 2000
problems in the Company's products could also result in delay or loss of
revenue, diversion of development resources, damage to the Company's reputation
or increased service or warranty costs, any of which could have a material
adverse effect on the Company's business, financial condition and results of
operations.

The foregoing discussion of the Company's Year 2000 readiness contains forward-
looking statements, including estimates of the timeframes and costs for
addressing the known Year 2000 issues confronting the Company, and is based on
management's current estimates, which were derived using numerous assumptions.
There can be no assurance that these estimates will be achieved, and actual
events and results could differ materially from those anticipated.  Specific
factors that might cause such material differences include, but are not limited
to, the availability of personnel with required remediation skills, the ability
of the Company to identify and correct all relevant computer code and the
success of third parties with whom the Company does business in addressing their
Year 2000 issues.

Item 2.   CHANGES IN SECURITIES AND USE OF PROCEEDS

          Foothill Warrant Exercise

          On April 19, 1999, the Company issued to Foothill 32,098 shares of the
          Company's common stock (the "Foothill Stock") at a per share price of
          $5.0296875, upon Foothill's exercise of a warrant to purchase
          75,000 shares of the Company's common stock. The aggregate purchase
          price of $161,442.91 for the Foothill Stock was paid by Foothill be
          means of the cancellation of the remaining 17,902 shares of common
          stock subject to the warrant, pursuant to the "cashless" exercise
          provision of the warrant. As the issuance of the Foothill Stock did
          not involve any public offering, it was exempt from registration under
          the Securities Act pursuant to Section 4(2) thereof. No underwriters
          were utilized in connection with the issuance of the Foothill Stock,
          and no underwriting discounts or commissions were paid or incurred
          thereby.

          CBS Warrant Issue

          On June 30, 1999, the Company issued to CBS Corporation a warrant to
          purchase 250,000 shares of the Company's common stock at a per share
          exercise price of $11.27. CBS has notified the Company in accordance
          with its agreement with the Company that as consideration for the
          issuance of the warrant, it will purchase from the Company an amount
          of information technology services sufficient for the Company to
          realize a margin of $250,000. As the issuance of the warrant did not
          involve any public offering, it was exempt from registration under the
          Securities Act pursuant to Section 4(2) thereof. No underwriters were
          utilized in connection with the issuance of the warrant, and no
          underwriting discounts or commissions were paid or incurred thereby.

as of June 1, 1999 is entered into by and among Switchboard Incorporated, a

would interrupt or interfere with the intended purpose thereof, including
without limitation, (A) any malfunctions or other usage problems resulting from
or in connection with the "Year 2000 Problem," and (B) "bugs" or "viruses."  For

presently used and (z) are sufficient for the continued conduct of the business
of the Company in substantially the same manner as the business of the Company
is conducted as of the date of this Agreement, except where such failures to
maintain, failures to be in good operating condition and repair, failures to be
suitable and failures to be sufficient would not have a Company Material Adverse
Effect.

Purchaser in Exhibit B-3 hereto, the Purchaser hereby represents and warrants to
             -----------
the Company and Banyan that the statements contained in this Section 4 are true,
complete and correct as of the date of this Agreement.  Exhibit B-3 shall be
                                                        -----------
organized into sections corresponding with the sections of this Section 4 and
the disclosure in any section of Exhibit B-3 shall be deemed to qualify (i) the
                                 -----------
corresponding section of this Section 4 and (ii) other sections of this Section
4 to the extent it is clearly apparent (notwithstanding the absence of a
specific cross reference) from a reading of such disclosure that such disclosure
is applicable to such other sections.

          4.1    Investment.  The Purchaser is acquiring the Shares, the Warrant
and the Voting Share, and, upon exercise of the Warrant, will be acquiring the
Warrant Shares, and, upon conversion of the Voting Share, will be acquiring the
Conversion Share, for its own account for investment and not with a view to, or
for sale in connection with, any distribution thereof, nor with any present
intention of distributing or selling the same; and, except as contemplated by
this Agreement and the Ancillary Agreements hereto, the Purchaser has no present
or contemplated agreement, undertaking, arrangement, obligation, indebtedness or
commitment providing for the disposition thereof.  The Purchaser is an
"accredited investor" as defined in Rule 501(a) under the Securities Act.

companies in the development stage and acknowledges that it is able to fend for
itself, can bear the economic risk of its investment and has such knowledge and
experience in financial or business matters that it is capable of evaluating the
merits and risks of the investment in the Shares, the Warrant and the Voting
Share and, upon exercise of the Warrant, the Warrant Shares, and, upon
conversion of the Voting Share, the Conversion Share. Purchaser has been
furnished with and has had access to such information as the Purchaser
considered necessary to make a determination as to the purchase of the Shares,
the Warrant and the Voting Share, and, upon exercise of the Warrant, the Warrant
Shares, and, upon conversion of the Voting Share, the Conversion Share.

conduct its business as presently conducted by it and to enter into and perform
this Agreement and the Ancillary Agreements and to carry out the transactions
contemplated by this Agreement and the Ancillary Agreements.

          4.4  Authority for Agreement; No Conflict.  The execution, delivery
and performance by the Purchaser of this Agreement and the Ancillary Agreements,
and the consummation by the Purchaser of the transactions contemplated hereby
and thereby, have been duly authorized by all necessary corporate action.  This
Agreement and the Ancillary Agreements, when executed at the Closing, will be
duly executed and delivered by the Purchaser and will constitute valid and
binding obligations of the Purchaser enforceable in accordance with their
respective terms, subject as to enforcement of remedies to applicable
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or
similar laws affecting generally the enforcement of creditors' rights and
subject to a court's discretionary authority with respect to the granting of a
decree ordering specific performance or other equitable remedies.  The execution
of and performance of the transactions contemplated by this Agreement and the
Ancillary Agreements and compliance with their respective provisions by the
Purchaser will not (a) conflict with or violate any provision of the Articles of
Incorporation or By-laws of the Purchaser, (b) other than as may be required by
the HSR Act, require on the part of the Purchaser any filing with, or any
permit, authorization, consent or approval of, any Governmental Entity, (c)

lapse of time or both) a default under, result in the acceleration of, create in
any party the right to accelerate, terminate, modify or cancel, or require any
notice, consent or waiver under, any contract, lease, sublease, license,
sublicense, franchise, permit, indenture, agreement or mortgage for borrowed
money, instrument of indebtedness, Security Interest or other arrangement to
which the Purchaser is a party or by which the Purchaser is bound or to which
its assets are subject, (d) result in the imposition of any Security Interest
upon any assets of the Purchaser or (e) violate any order, writ, injunction,
decree, statute, rule or regulation

                                      -15-

applicable to the Purchaser or any of its properties or assets, other than any
of the foregoing events listed in clause (c), (d) or (e) of this Section 4.4
that would not have a material adverse effect on the ability of the Purchaser to
perform its obligations under this Agreement and the Ancillary Agreements (a
"Purchaser Material Adverse Effect").

          4.5  Governmental Consents.  Except as may be required by the HSR
Act, no consent, approval, order or authorization of, or registration,
qualification, designation, declaration or filing with, any Governmental Entity
is required on the part of the Purchaser in connection with the execution and
delivery by the Purchaser of this Agreement or the Ancillary Agreements, except
such filings as shall have been made prior to and shall be effective on and as
of the Closing, and except any filings that, if not made as required, would not
have a Purchaser Material Adverse Effect.

          4.6  Litigation.  There is no action, suit or legal proceeding, or
governmental inquiry or investigation, pending against the Purchaser or, to the
Purchaser's knowledge, threatened against the Purchaser which questions the
validity of this Agreement or the Ancillary Agreements or the right of the
Purchaser to enter into this Agreement or the Ancillary Agreements, or which

     6.   Transfer of Shares.
          ------------------

          6.1    Restricted Shares.  "Restricted Shares" means (i) the Shares,
(ii) the Warrant Shares, (iii) the Voting Share, (iv) the Conversion Share, and
(v) any other shares of capital stock of the Company issued in respect of the
shares of Common Stock referred to in (i), (ii), (iii) and (iv) (as a result of
stock splits, stock dividends, reclassifications, recapitalizations, or similar
events); provided, however, that shares of Common Stock which are Restricted
Shares shall cease to be Restricted Shares (x) upon any sale pursuant to a
registration statement under the Securities Act, Section 4(1) of the Securities
Act or Rule 144 under the Securities Act or (y) at such time as they become
eligible for sale under Rule 144(k) under the Securities Act.

          6.2    Limitations on and Requirements for Transfer.
                 --------------------------------------------

          (a)    None of the Shares, or the Warrant or, upon exercise of the
Warrant, the Warrant Shares, upon conversion of the Voting Share, the Conversion
Share (or any other shares of capital stock of the Company issued in respect of
the Shares, or the Warrant or, upon exercise of the Warrant, the Warrant Shares,
or, upon conversion of the Voting Share, the Conversion Share) nor any interest
in such securities may be sold, assigned, pledged, or otherwise transferred
until the earlier of (i) the second anniversary of the Closing Date and (ii) the
closing of the Company's initial underwritten public offering of Common Stock
registered under the Securities Act pursuant to an effective registration
statement.  Neither the Voting Share, nor any interest therein may be sold,

foregoing, the Purchaser may transfer all (but not less than all) of the Shares,
the Warrant or, upon exercise of the Warrant, the Warrant Shares, and the Voting
Share, and upon conversion of the Voting Share, the Conversion Share, to any

                                      -18-

(1) written notice of such action is provided to the Company and Banyan, (2) the
transferee agrees in writing as part of such notice to be bound by this
Agreement and (3) CBS Corporation remains primarily responsible for the
performance of all of the obligations of the Purchaser hereunder.  The Shares,
the Warrant and, upon exercise of the Warrant, the Warrant Shares (or any other
shares of capital stock of the Company issued in respect of the Shares, the
Warrant or, upon exercise of the Warrant, the Warrant Shares) are also subject
to the restrictions on transfer and other provisions of the Ancillary
Agreements.

          (b) In addition, Restricted Shares shall not be sold or transferred
unless either (i) they first shall have been registered under the Securities
Act, or (ii) the Company first shall have been furnished with an opinion of
legal counsel, reasonably satisfactory to the Company, to the effect that such
sale or transfer is exempt from the registration requirements of the Securities
Act.

          6.3    Legend.  Each certificate representing Restricted Shares shall
bear legends substantially in the following form:

             "The shares represented by this certificate have not been
             registered under the Securities Act of 1933, as amended, and may
             not be offered, sold or otherwise transferred, pledged or
             hypothecated unless and until such shares are registered under such
             Act or an opinion of counsel satisfactory to the Company is
             obtained to the effect that such registration is not required."

             "The shares represented by this certificate are subject to the
             restrictions on transfer set forth in the Common Stock and Warrant
             Purchase Agreement between the Company and the holder hereof, a
             copy of which is available for inspection of the office of the

          ---------------

to the limitation set forth in Section 8.4(b), Banyan, jointly and severally,
shall indemnify Purchaser and its affiliates and their respective officers,
directors, employees, agents and representatives against, and hold them harmless
from, any loss, liability, claim, damage or expense (including reasonable legal
fees and expenses) ("Losses"), actually incurred by them, as incurred (payable
promptly upon written request), arising from, in connection with or otherwise
with respect to:

          (a) with respect to (x) the Company, any breach of any representation
or warranty of the Company contained in this Agreement, in any Ancillary
Agreement (other than the Advertising and Promotion Agreement and the License
Agreement) or in the closing certificate delivered at the Closing pursuant to
Section 7.2(a) and (y) Banyan, any breach of any representation or warranty of
the Company or Banyan contained in this Agreement, in any Ancillary Agreement
(other than the Advertising and Promotion Agreement and the License Agreement)
or in the closing certificate delivered at the Closing pursuant to Section
7.2(a);

          (b) any breach of any covenant of the Company contained in this
Agreement or in any Ancillary Agreement (other than the Advertising and
Promotion Agreement and the License Agreement); and

          (c) the matters identified on Schedule 8.1(c).

          8.2  Indemnification by Purchaser.  Purchaser shall indemnify the
Company and Banyan and each of their respective officers, directors, employees,
agents and representatives against, and hold them harmless from, any Losses,
actually incurred by them, as incurred (payable promptly upon written request),
arising from, in connection with or otherwise with respect to:

                                      -24-
<PAGE>

          (a) any breach of any representation or warranty of Purchaser
contained in this Agreement, in any Ancillary Agreement (other than the
Advertising and Promotion Agreement and the License Agreement) or in the closing
certificate delivered at the Closing pursuant to Section 7.3(a); and

          (b) any breach of any covenant of Purchaser contained in this
Agreement or in any Ancillary Agreement (other than the Advertising and
Promotion Agreement and the License Agreement).

          8.3  Calculation of Losses.  The amount of any Loss for which
indemnification is provided under this Section 8 shall be calculated net of any
amounts actually recovered by the indemnified party under insurance policies
with respect to such Loss and shall be (i) increased to take account of any net
tax cost incurred by the indemnified party arising from the receipt of indemnity
payments hereunder (grossed up for such increase) and (ii) reduced to take
account of any net tax benefit realized by the indemnified party arising from
the incurrence or payment of any such Loss.  In computing the amount of any such
tax cost or tax benefit, the indemnified party shall be deemed to recognize all
other items of income, gain, loss deduction or credit before recognizing any
item arising from the receipt of any indemnity payment hereunder or the
incurrence or payment of any indemnified Loss.

          8.4  Termination of Indemnification.
               ------------------------------

          (a) The obligations to indemnify and hold harmless any party, pursuant
to Sections 8.1(a) or 8.2(a), shall terminate upon the second anniversary of the
Closing Date; provided, however, that such obligations to indemnify and hold
              -----------------
harmless shall not terminate with respect to any item as to which the person to
be indemnified shall have, before such anniversary date, previously made a claim
by delivering a notice of such claim (stating in reasonable detail the basis of
such claim) pursuant to Section 8.5 to the party to be providing the
indemnification.

          (b) Notwithstanding anything to the contrary in this Agreement,
Banyan's indemnification obligations hereunder with respect to the covenants of
the Company and Banyan and the representation and warranty in Section 3.12(f)
shall terminate upon the earlier to occur of:

               (x) the first business day after the second anniversary of the
                   Closing Date when Banyan beneficially owns or controls,
                   directly or indirectly, shares of capital stock of the
                   Company representing less than a majority of the total voting
                   power; and

                                      -25-
<PAGE>

               (y) the first business day after any person or entity
                   beneficially owns or controls, directly or indirectly, shares
                   of the capital stock of the Company representing more voting
                   power (based on then-outstanding shares) than those
                   beneficially owned or controlled, directly or indirectly, by
                   Banyan.

; provided, however, that Banyan's indemnification obligations shall not
  -----------------
terminate pursuant to this provision with respect to an item as to which the
Purchaser has, before the occurrence of either of the events set forth above,
previously made a claim by delivering a notice of such claim (stating in
reasonable detail the basis for such claim) pursuant to Section 8.5 to Banyan.
For purposes of performing the calculation of beneficial ownership and control
referred to in the preceding sentence, neither Banyan nor the Purchaser shall be
deemed to beneficially own or control shares solely as a result of the existence
of the Stockholders' Voting Agreement.

          8.5  Procedures.
               ----------

          (a) In order for a party (the "indemnified party"), to be entitled to
                                         -----------------
any indemnification provided for under this Agreement in respect of, arising out
of or involving a claim made by any person against the indemnified party (a
"Third Party Claim"), such indemnified party must notify the indemnifying party
 -----------------
in writing of the Third Party Claim promptly following receipt by such
indemnified party of written notice of the Third Party Claim; provided, however,
                                                              -----------------
that failure to give such notification shall not affect the indemnification
provided hereunder except to the extent the indemnifying party shall have been
actually prejudiced as a result of such failure. Thereafter, the indemnified
party shall deliver to the indemnifying party, promptly following the
indemnified party's receipt thereof, copies of all notices and documents
(including court papers) received by the indemnified party relating to the Third
Party Claim and not also addressed to the indemnifying party.

          (b) If a Third Party Claim is made against an indemnified party, the
indemnifying party shall be entitled to participate in the defense thereof and,
if it so chooses, to assume the defense thereof with counsel selected by the
indemnifying party; provided, however, that such counsel is not reasonably
                    -----------------
objected to by the indemnified party.  Should the indemnifying party so elect to
assume the defense of a Third Party Claim, the indemnifying party shall not be
liable to the indemnified party for any legal expenses subsequently incurred by
the indemnified party in connection with the defense thereof.  If the
indemnifying party assumes such defense, the indemnified party shall have the
right to participate in the defense thereof and to employ counsel, at its own
expense, separate from the counsel employed by the indemnifying party, it being
understood that the indemnifying party shall control such defense.  The
indemnifying party shall be liable for the fees and expenses of counsel employed
by the indemnified party for any period during which the indemnifying

                                      -26-
<PAGE>

party has not assumed the defense thereof. If the indemnifying party chooses to
defend or prosecute a Third Party Claim, all the indemnified parties shall
cooperate in the defense or prosecution thereof. Such cooperation shall include
the retention and (upon the indemnifying party's request) the provision to the
indemnifying party of records and information that are reasonably relevant to
such Third Party Claim, and making employees available on a mutually convenient
basis to provide additional information and explanation of any material provided
hereunder. Whether or not the indemnifying party assumes the defense of a Third
Party Claim, the indemnified party shall not admit any liability with respect
to, or settle, compromise or discharge, such Third Party Claim without the
indemnifying party's prior written consent (which consent shall not be
unreasonably withheld). If the indemnifying party assumes the defense of a Third
Party Claim, the indemnified party shall agree to any settlement, compromise or
discharge of a Third Party Claim that the indemnifying party may recommend and
that by its terms obligates the indemnifying party to pay the full amount of the
liability in connection with such Third Party Claim, which releases the
indemnified party completely in connection with such Third Party Claim and that
would not otherwise adversely affect the indemnified party. Notwithstanding the
foregoing, the indemnifying party shall not be entitled to assume the defense of
any Third Party Claim (and shall be liable for the fees and expenses of counsel
incurred by the indemnified party in defending such Third Party Claim) if the
Third Party Claim seeks an order, injunction or other equitable relief or relief
for other than money damages against the indemnified party that the indemnified
party reasonably determines, after conferring with its outside counsel, would
reasonably be expected to have a material adverse effect on the assets,
business, financial condition of results of operations of the indemnified party
and cannot be separated from any related claim for money damages; provided,
                                                                  --------
however, that the indemnifying party will not be bound by any determination in
- -------
such Third Party Claim so defended by the indemnified party, or any compromise
or settlement effected without its consent. If such equitable relief or other
relief portion of the Third Party Claim can be so separated from that for money
damages, the indemnifying party shall be entitled to assume the defense of the
portion relating to money damages.

          (c) Other Claims.  In the event any indemnified party has a claim
against any indemnifying party under Section 8.1 or 8.2 that does not involve a
Third Party Claim being asserted against or sought to be collected from such
indemnified party, the indemnified party shall deliver notice of such claim with
reasonable promptness to the indemnifying party.  The failure by any indemnified
party so to notify the indemnifying party shall not relieve the indemnifying
party from any liability that it may have to such indemnified party under
Section 8.1 or 8.2, except to the extent the indemnifying party shall have been
actually prejudiced as a result of such failure.  If the indemnifying party does
not notify the indemnified party within 30 calendar days following its receipt
of such notice that the indemnifying party disputes its liability to the
indemnified party under Section 8.1 or 8.2, such claim

                                      -27-
<PAGE>

specified by the indemnified party in such notice shall be conclusively deemed a
liability of the indemnifying party under Section 8.1 or 8.2 and the
indemnifying party shall pay the amount of such liability to the indemnified
party on demand or, in the case of any notice in which the amount of the claim
(or any portion thereof) is estimated, on such later date when the amount of
such claim (or such portion thereof) becomes finally determined. If the
indemnifying party has timely disputed its liability with respect to such claim,
as provided above, the indemnifying party and the indemnified party shall
proceed in good faith to negotiate a resolution of such dispute and, if not
resolved through negotiations, any party may commence litigation in an
appropriate court of competent jurisdiction.

          (d) Payment of Amounts Due.  Notwithstanding any other provision in
this Agreement to the contrary, all or part of any claim by an indemnified party
to recover Losses under Section 8.1 may be settled by the issuance or transfer
by an indemnified party of securities of the Company having a fair market value
(as agreed to in good faith by the parties involved) equal to the portion of
such claim to be so satisfied.

          8.6  Survival of Representations.  The representations and warranties
contained in this Agreement, in any Ancillary Agreement (other than the
Advertising and Promotion Agreement and the License Agreement, which shall
survive in accordance with their terms) and in the closing certificates
delivered at the closing pursuant to Sections 7.2(a) and 7.3(a) shall survive
the Closing and shall terminate at the close of business two years following the
Closing Date.

          8.7  Limitations.
               -----------

          (a) Except with respect to claims based on actual fraud, from and
after the Closing, the rights of the indemnified parties under this Section 8
shall be the sole and exclusive remedies of the indemnified parties and their
respective affiliates with respect to claims resulting from or relating to any
actual or alleged breach of representation or warranty or failure to perform any
covenant contained in this Agreement or otherwise relating to the transactions
that are the subject of this Agreement. Without limiting the generality of the
foregoing, in no event shall the Company, Banyan or the Purchaser, their
successors or permitted assigns, be entitled to claim or seek rescission of the
transactions consummated under this Agreement.

          (b) Notwithstanding anything to the contrary contained in this
Agreement, but subject to the provisos set forth below in this Section 8.7(b),
the aggregate liability of the Company and Banyan for the sum of all Losses
under this Section 8 and under the Advertising and Promotion Agreement shall be
limited to the amount specified in the following table:

                                      -28-

; provided, however, that if parties entitled to indemnification under Section
8.1 suffer Losses as a result of a breach of any representation or warranty of
the Company or Banyan contained in this Agreement or in the closing certificate
delivered at the Closing pursuant to Section 7.2(a) in an amount which exceeds
the applicable limitation on liability set forth in the preceding table, then
such indemnified parties shall be entitled to recover such excess Losses in
future years (in each case up to the applicable limitation on liability set
forth in the preceding table for each such future year); provided, further,
however, that the aggregate liability of the Company and Banyan for the sum of
all Losses under this Section 8 and under the Advertising and Promotion
Agreement in a circumstance where the immediately foregoing proviso clause
applies shall in no circumstance exceed the sum of $5 million plus the aggregate
amount of Non-Cash Purchase Price actually received by the Company.

          (c) In no event shall any indemnifying party be responsible and liable
for any Losses or other amounts under this Section 8 that are consequential,
incidental, in the nature of lost profits, diminution in value, damage to
reputation or the like, special or punitive or otherwise not actual Losses.

                                      -29-
<PAGE>

          (d) For the avoidance of doubt, the parties acknowledge that in no
circumstance shall the Company be liable with respect to claims resulting from
or relating to any actual or alleged breach of representation or warranty
contained in Section 3A of this Agreement.

          8.8  Indemnification of Banyan by the Company. The Company shall
indemnify Banyan and its affiliates (other than the Company) and their
respective officers, directors, employees, agents and representatives against,
and hold them harmless from, any Losses, actually incurred by them, as incurred
(payable promptly upon written request), arising from, in connection with or
otherwise with respect to any indemnification obligation of Banyan to the
Purchaser under this Agreement or any Ancillary Agreement (other than (1) with
respect to the representations and warranties of Banyan contained in Section 3A
of this Agreement or (2) a breach by Banyan of its covenant in Section 5.5).

                                AMENDMENT NO. 1

                                      TO

                  COMMON STOCK AND WARRANT PURCHASE AGREEMENT
                  -------------------------------------------

     This Amendment No. 1 (the "Amendment") to the Common Stock and Warrant
Purchase Agreement dated as of June 1, 1999 (the "Agreement"), by and among
Switchboard Incorporated, a Delaware corporation (the "Company"), Banyan Systems
Incorporated, a Massachusetts corporation ("Banyan") and CBS Corporation, a
Pennsylvania corporation (the "Purchaser"), is entered into as of the 30th day
of June, 1999.  Capitalized terms used herein and not otherwise defined shall
have the same meaning as in the Agreement.

     WHEREAS, the number of shares being issued to CBS pursuant to the Agreement
and the number of shares subject to the Warrant being issued to CBS pursuant to
the Agreement were determined by reference to the Company's fully-diluted
capitalization, based in part on certain assumptions regarding the number of
shares of Series C Preferred Stock and/or Series D Preferred Stock that would be
outstanding on the Closing Date;

     WHEREAS, the actual number of shares of Series C Preferred Stock and/or
Series D Preferred Stock that are outstanding on the Closing Date is higher than
was previously assumed;

     WHEREAS, the Parties desire to amend the Agreement to adjust the number of
shares being issued to CBS pursuant to the Agreement and the number of shares
subject to the Warrant being issued to CBS pursuant to the Agreement;

     NOW, THEREFORE, for good and valuable consideration, the receipt of which
is hereby acknowledged, the parties hereto agree as follows:

     1.  Section 1(a) of the Agreement is hereby amended and restated in its
entirety to read as follows:

     1.   Sale of Securities; Authorization.
          ---------------------------------

          (a) Subject to the terms and conditions of this Agreement, at the
Closing (as defined below), the Company will sell and issue to the Purchaser,
and the Purchaser will purchase from the Company, (i) 7,463,216 shares (the
"Shares") of Common Stock (as defined in Section 3.2), (ii) a warrant to
purchase 1,066,174 shares of Common Stock, in the form attached hereto as
Exhibit A-1 (the "Warrant"), and (iii) one share of Series E Special Voting
- -----------
Preferred Stock, $.01 par value per share, of the
<PAGE>

Company (the "Voting Share"), for the aggregate purchase price of (x) $5,000,000
(the "Cash Purchase Price"), which shall be paid in cash at the Closing, and (y)
$95,000,000 (the "Non-Cash Purchase Price"), which shall be paid through the
provision by the Purchaser to the Company of advertising services in accordance
with the Advertising and Promotion Agreement (as defined herein). The Cash
Purchase Price and the Non-Cash Purchase Price are sometimes referred to herein
together as, the "Purchase Price." Subject to the provisions of the License
Agreement (as defined herein) and the Advertising and Promotion Agreement, the
obligation of the Purchaser to pay the Non-Cash Purchase Price is a binding
obligation of the Purchaser. The Purchase Price shall be allocated among the
Shares, the Warrant and the Voting Share as set forth on Schedule 1.2 hereto.
                                                         ------------

     2.   This Amendment may be executed in two or more counterparts, each of
which shall be deemed an original but all of which together shall constitute one
and the same instrument.  This Amendment may be executed by facsimile signature.

     3.   Except as amended hereby, the Agreement shall remain in full force and
effect in accordance with its terms.  If there are any conflicts between the
terms of the Agreement and this Amendment, then this Amendment shall control.

                                      -2-

     IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of
the date set forth above.

<PAGE>

     1.   Exercise.
          --------

          (a) This Warrant may be exercised by the Registered Holder, in whole
or in part, by surrendering this Warrant, with the purchase form appended hereto
as Exhibit I duly executed by the Registered Holder or by the Registered
Holder's duly authorized attorney, at the principal office of the Company, or at
such other office or agency as the Company may designate, accompanied by payment
(by wire transfer) in full, in lawful money of the United States, of the

such exercise.

          (b) Each exercise of this Warrant shall be deemed to have been
effected immediately prior to the close of business on the day (the "Exercise
Date") on which this Warrant shall have been surrendered to the Company as
provided in Section 1(a) above.  At such time, the Registered Holder shall be
deemed to have become the holder of record of the Warrant Shares.

          (c) As soon as practicable after the exercise of this Warrant in full
or in part, and in any event within 15 days thereafter, the Company, at its
expense, will cause to be issued in the name of, and delivered to, the

                     agreement or arrangement adopted by the Board of Directors
                     of the Company;

               (IV)  in the Company's initial public offering pursuant to a
                     registration statement under the Securities Act;

               (V)   pursuant to the Stock Warrant Agreement by and among the

                     Media Ventures, Inc., SBC Interactive and U.S. West Dex,
                     Inc., dated March 31, 1999, as it may be amended from time

                                      -3-
<PAGE>

               (VII)  pursuant to the Technology Development and Marketing

                      Inc., dated November 7, 1997, as it may be amended from
                      time to time; or

               (VIII) pursuant to any future borrowing, loan, line of credit,
                      leasing or similar financing arrangement with a bank,
                      commercial lender, leasing company or other person or for
                      any other purpose (provided that the shares issuable under
                      this clause (VIII) shall be limited to a maximum of
                      100,000).

          The share number references in (III) and (VIII) are subject to
appropriate adjustment in the event of any stock dividend, stock split,
combination or other similar event affecting such shares.

          (ii)  No Adjustment of Purchase Price.  No adjustments to the
Purchase Price shall be made unless the consideration per share (determined
pursuant to Section 2(b)(v)) for an Additional Share of Common Stock issued or
deemed to be issued by the Company is less than $16.00 (subject to adjustment in
the same manner as the Purchase Price pursuant to Sections 2(c) and 2(d) below)
(the "Adjustment Price").

          (iii)  Issue of Securities Deemed Issue of Additional Shares of Common
Stock. If the Company at any time or from time to time after the Original Issue
Date shall issue (whether by sale or grant) any Options or Convertible
Securities or shall fix a record date for the determination of holders of any
class of securities entitled to receive any such Options or Convertible
Securities, then the maximum number of shares of Common Stock (as set forth in
the instrument relating thereto without regard to any provision contained
therein for a subsequent adjustment of such number) issuable upon the exercise
of such Options or, in the case of Convertible Securities and Options therefor,
the conversion or exchange of such Convertible Securities, shall be deemed to be
Additional Shares of Common Stock issued as of the time of such issue or, in
case such a record date shall have been fixed, as of the close of business on
such record date, provided that Additional Shares of Common Stock shall not be
deemed to have been issued unless the consideration per share (determined
pursuant to Section 2(b)(v) hereof) of such Additional Shares of Common Stock
would be less than the Adjustment Price in effect on the date of and immediately
prior to such issue, or such record date, as the case may be, and provided
further that in any such case in which Additional Shares of Common Stock are
deemed to be issued:

          (A) No further adjustment in the Purchase Price shall be made upon the
subsequent issue of Convertible Securities or shares of Common Stock upon the
exercise of such Options or conversion or exchange of such Convertible
Securities;

                                      -4-
<PAGE>

          (B) If such Options or Convertible Securities by their terms provide,
with the passage of time or otherwise, for any increase or decrease in the
consideration payable to the Company, then upon the exercise, conversion or
exchange thereof, the Purchase Price computed upon the original issue thereof
(or upon the occurrence of a record date with respect thereto), and any
subsequent adjustments based thereon, shall, upon any such increase or decrease
becoming effective, be recomputed to reflect such increase or decrease insofar
as it affects such Options or the rights of conversion or exchange under such
Convertible Securities;

          (C) Upon the expiration or termination of any such unexercised Option,
the Purchase Price shall not be readjusted, but the Additional Shares of Common
Stock deemed issued as the result of the original issue of such Option shall not
be deemed issued for the purposes of any subsequent adjustment of the Purchase
Price;

          (D) In the event of any change in the number of shares of Common Stock
issuable upon the exercise, conversion or exchange of any such Option or
Convertible Security, including, but not limited to, a change resulting from the
anti-dilution provisions thereof, the Purchase Price then in effect shall
forthwith be readjusted to such Purchase Price as would have obtained had the
adjustment which was made upon the issuance of such Option or Convertible
Security not exercised, converted or exchanged prior to such change been made
upon the basis of such change; and

          (E) No readjustment pursuant to clause (B) or (D) above shall have the
effect of increasing the Purchase Price to an amount which exceeds the lower of
(i) the Purchase Price on the original adjustment date, or (ii) the Purchase
Price that would have resulted from any issuances of Additional Shares of Common
Stock between the original adjustment date and such readjustment date.

          (iv)  Adjustment of Purchase Price Upon Issuance of Additional
Shares of Common Stock.  In the event the Company shall at any time after the
Original Issue Date issue Additional Shares of Common Stock (including
Additional Shares of Common Stock deemed to be issued pursuant to Section
2(b)(iii), but excluding shares issued as a dividend or distribution or upon a
stock split or combination as provided in Section 2(c)), without consideration
or for a consideration per share less than the Adjustment Price in effect on the
date of and immediately prior to such issue, then and in such event, the
Purchase Price shall be reduced, concurrently with such issue, to a price
(calculated to the nearest cent) determined by multiplying such Purchase Price
by a fraction, (A) the numerator of which shall be (1) the number of shares of
Common

                                      -5-
<PAGE>

Stock outstanding immediately prior to such issue plus (2) the number of
shares of Common Stock which the aggregate consideration received or to be
received by the Company for the total number of Additional Shares of Common
Stock so issued would purchase at the Adjustment Price; and (B) the denominator
of which shall be the number of shares of Common Stock outstanding immediately
prior to such issue plus the number of such Additional Shares of Common Stock so
issued; provided that, (i) for the purpose of this Section 2(b)(iv), all shares
of Common Stock issuable upon exercise, conversion or exchange of Options or
Convertible Securities outstanding immediately prior to such issue shall be
deemed to be outstanding, and (ii) the number of shares of Common Stock deemed
issuable upon exercise, conversion or exchange of such outstanding Options and
Convertible Securities shall not give effect to any adjustments to the exercise
or conversion price or rate of such Options or Convertible Securities resulting
from the issuance of Additional Shares of Common Stock that is the subject of
this calculation.  For the avoidance of doubt, any shares of Common Stock held
by the Company as treasury shares shall not be deemed to be outstanding.

          Notwithstanding the foregoing, the applicable Purchase Price shall not
be so reduced at such time if the amount of such reduction would be an amount
less than $.05, but any such amount shall be carried forward and reduction with
respect thereto made at the time of and together with any subsequent reduction
which, together with such amount and any other amount or amounts so carried
forward, shall aggregate $.05 or more.

          (v) Determination of Consideration.  For purposes of this Section
2(b), the consideration received by the Company for the issue of any Additional
Shares of Common Stock shall be computed as follows:

              (A) Cash and Property:  Such consideration shall:
                  -----------------

                  (I)   insofar as it consists of cash, be computed at the
aggregate of cash received by the Company, excluding amounts paid or payable for
accrued interest or accrued dividends;

                  (II)  insofar as it consists of property other than cash, be
computed at the fair market value thereof, as determined in good faith by the
Board of Directors; and

                  (III) in the event Additional Shares of Common Stock are
issued together with other shares or securities or other assets of the Company
for consideration which covers both, be the proportion of such consideration so
received, computed as provided in clauses (I) and (II) above, as determined in
good faith by the Board of Directors.

                                      -6-
<PAGE>

          (B) Options and Convertible Securities.  The consideration per share
received by the Company for Additional Shares of Common Stock deemed to have
been issued pursuant to Section 2(b)(iii), relating to Options and Convertible
Securities, shall be determined by dividing

                   (x) the total amount, if any, received or receivable by the
Company as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such consideration) payable to
the Company upon the exercise of such Options or the conversion or exchange of
such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the
conversion or exchange of such Convertible Securities, by

                   (y) the maximum number of shares of Common Stock (as set
forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

              (vi)  Multiple Closing Dates.  In the event the Company shall
issue on more than one date Additional Shares of Common Stock which are
comprised of shares of the same series or class of Preferred Stock, and such
issuance dates occur within a period of no more than 120 days, then the Purchase
Price shall be adjusted only once on account of such issuances, with such
adjustment to occur upon the final such issuance and to give effect to all such
issuances as if they occurred on the date of the final such issuance.

              (vii) Limitation.  Notwithstanding anything in this Warrant
to the contrary, in no event shall the Purchase Price be adjusted pursuant to
Section 2(b) to below $0.01 per share.

          (c) Recapitalizations.  If outstanding shares of the Company's Common
Stock shall be subdivided into a greater number of shares or a dividend in
Common Stock shall be paid in respect of Common Stock, the Purchase Price in
effect immediately prior to such subdivision or at the record date of such
dividend shall simultaneously with the effectiveness of such subdivision or
immediately after the record date of such dividend be proportionately reduced.
If outstanding shares of Common Stock shall be combined into a smaller number of
shares, the Purchase Price in effect immediately prior to such combination
shall, simultaneously with the effectiveness of such combination, be
proportionately increased.

                                      -7-
<PAGE>

          (d) Mergers, etc.  If there shall occur any capital reorganization or
reclassification of the Company's Common Stock (other than a change in par value
or a subdivision or combination as provided for in Section 2(c) above), or any
consolidation or merger of the Company with or into another corporation, or a
transfer of all or substantially all of the assets of the Company, then, as part
of any such reorganization, reclassification, consolidation, merger or sale, as
the case may be, lawful provision shall be made so that the Registered Holder
shall have the right thereafter to receive upon the exercise hereof the kind and
amount of shares of stock or other securities or property which such Registered
Holder would have been entitled to receive if, immediately prior to any such
reorganization, reclassification, consolidation, merger or sale, as the case may
be, such Registered Holder had held the number of shares of Common Stock which
were then purchasable upon the exercise of this Warrant.  In any such case,
appropriate adjustment (as reasonably determined in good faith by the Board of
Directors of the Company) shall be made in the application of the provisions set
forth herein with respect to the rights and interests thereafter of the
Registered Holder, such that the provisions set forth in this Section 2
(including provisions with respect to adjustment of the Purchase Price) shall
thereafter be applicable, as nearly as is reasonably practicable, in relation to
any shares of stock or other securities or property thereafter deliverable upon
the exercise of this Warrant.

          (e) Adjustment in Number of Warrant Shares.  When any adjustment is
required to be made in the Purchase Price pursuant to Section 2(c), the number
of Warrant Shares purchasable upon the exercise of this Warrant shall be changed
to the number determined by dividing (i) an amount equal to the number of shares
issuable upon the exercise of this Warrant immediately prior to such adjustment,
multiplied by the Purchase Price in effect immediately prior to such adjustment,
by (ii) the Purchase Price in effect immediately after such adjustment.

          (f) Certificate of Adjustment.  When any adjustment is required to be
made pursuant to this Section 2, the Company shall promptly mail to the
Registered Holder a certificate setting forth the Purchase Price after such
adjustment and setting forth a brief statement of the facts requiring such
adjustment.  Such certificate shall also set forth the kind and amount of stock
or other securities or property into which this Warrant shall be exercisable
following such adjustment.

     3.   Fractional Shares.  The Company shall not be required upon the
exercise of this Warrant to issue any fractional shares, but shall make an
adjustment therefor in cash on the basis of the fair market value per share of
Common Stock, as determined in good faith by the Board of Directors of the
Company.

     4.   Requirements for Transfer.  Neither this Warrant nor any interest
herein is transferrable in any respect (other than to the Company or Banyan
Systems Incorporated); provided, however, that notwithstanding the foregoing,
                       --------  -------
the Registered

                                      -8-
<PAGE>

Holder may transfer the entire Warrant (but not less than the entire Warrant) to
any entity controlling, controlled by or under common control of the Registered
Holder if (1) written notice of such action is provided to the Company, (2) the
transferee agrees in writing as part of such notice to be bound by this
Agreement and (3) CBS Corporation remains primarily responsible for the
performance of all of the obligations of the Registered Holder hereunder. The
Warrant and the Warrant Shares are also subject to the restrictions on transfer
set forth in the Common Stock and Warrant Purchase Agreement dated as of June 1,
1999 between the Company and the Registered Holder, which terms are incorporated
herein.

     5.   No Impairment.  The Company will not, by amendment of its charter or
through reorganization, consolidation, merger, dissolution, sale of assets or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant, but will at all times in good faith assist
in the carrying out of all such terms and in the taking of all such action as
may be necessary or appropriate, including such action as may be necessary or
appropriate in order that the Company may validly and legally issue or sell
fully paid and non-assessable Warrant Shares upon exercise of this Warrant, in
order to protect the rights of the holder of this Warrant against impairment.

     6.   Notices of Record Date, etc.  In case:
          ---------------------------

          (a) the Company shall take a record of the holders of its Common Stock
(or other stock or securities at the time deliverable upon the exercise of this
Warrant) for the purpose of entitling or enabling them to receive any dividend
or other distribution, or to receive any right to subscribe for or purchase any
shares of stock of any class or any other securities, or to receive any other
right; or

          (b) of any capital reorganization of the Company, any reclassification
of the Common Stock of the Company, any consolidation or merger of the Company
with or into another corporation (other than a consolidation or merger in which
the Company is the surviving entity), or any transfer of all or substantially
all of the assets of the Company; or

          (c) of the voluntary or involuntary dissolution, liquidation or
winding-up of the Company,

then, and in each such case, the Company will mail or cause to be mailed to the
Registered Holder a notice specifying, as the case may be, (i) the record date
for such dividend, distribution or right, and the amount and character of such
dividend, distribution or right, or (ii) the effective date on which such
reorganization, reclassification, consolidation, merger, transfer, dissolution,
liquidation or winding-up is to take place, and the time, if any is to be fixed,

exercise of this Warrant) shall be entitled to exchange their shares of Common
Stock (or such other stock or securities) for securities or other property

transfer, dissolution, liquidation or winding-up. Such notice shall be mailed at

Shares shall be duly authorized and, when issued upon such exercise, shall be
validly issued, fully paid and non-assessable and free and clear of all
preemptive rights, and free from all taxes, liens and other charges with respect
to the issue thereof by the Company.  The Company will take all actions as may
be necessary to assure that the Warrant Shares issued upon a valid exercise
hereof may be issued by the Company without violation of any law or regulation,
or of any requirement of any domestic securities exchange upon which any capital
stock of the Company may be listed.

     8.   Replacement of Warrants.  Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and (in the case of loss, theft or destruction) upon delivery of an
indemnity agreement (with surety if reasonably required) in an amount reasonably
satisfactory to the Company, or (in the case of mutilation) upon surrender and
cancellation of this Warrant, the Company will issue, in lieu thereof, a new
Warrant of like tenor.

registered mail, postage prepaid, to the address last furnished to the Company
in writing by the Registered Holder.  All notices and other communications from

dollars ($18,900,000) during any given Contract Year.

          (b) (2.1 (b)) [**] all broadcast advertising and promotion provided
hereunder shall be based upon [**] purchased during the specific CBS Television
Network, CBS Owned and Operated Television Station, CBS Owned and Operated Radio
Station, or CBS Cable broadcast in which the advertising or promotion occurs.
Banner advertising on CBS Internet sites shall [**] in which [**]. The price of
the billboard ad concerned shall be based on [**] during the month previous to
the month in which such advertising is delivered. CBS shall [**]. CBS will
provide to Switchboard quarterly statements, or, if available, monthly
statements showing the advertising and promotional value [**] with respect to
the advertising and promotions purchased by Switchboard during the statement
period.

          (c) Subject to the written consent of CBS, which consent may be
unreasonably withheld, Switchboard may elect to use a portion of the promotional
value described in Section 2.1(a) to promote, through radio spots or billboard
advertisements only, certain of Switchboard's significant third party business
partners.

     2.2  CBS will maintain accurate books and records which report the
expenditure of the advertising and promotional value by Switchboard and
information from which the calculation can be derived.  Switchboard may, at its
own expense, examine and copy those books and records, as provided in this
Section 2.2.  Switchboard may make such an examination for a particular
statement provided pursuant to Section 2.1(b) within three (3) years after the
date such statement is sent by CBS to Switchboard.  Switchboard may make those
examinations only during CBS's usual business hours, and at the place where it
keeps the books and records.  Such books and records shall be kept at the
address set forth herein for the provision of notices to CBS, unless otherwise
notified.  Switchboard will be required to notify CBS at least ten (10) days
before the date of planned examination.

     2.3  CBS shall have the right to suspend and/or withdraw placement of all
advertising and promotion:

          (a) (x) pending resolution of any claim covering use by the Company in
the United States of the tradename or trademark "Switchboard" either alone or in
combination with any other mark and/or (y) during such time as the Company is
enjoined from using the tradename or trademark "Switchboard" in the United
States on or in connection with the Switchboard Site and has not renamed the
Switchboard Site.  (In connection with clause (x) of the foregoing sentence, CBS
shall use its reasonable judgment in suspending or withdrawing advertising,
taking into account the substance of the claim, the potential liabilities to
which CBS may be subject and the potential detriment to CBS's interests or
business.)  The Company shall rename the Switchboard Site within thirty (30)
days following the issuance of any injunction or the resolution of any claim
which requires the Company to cease using the tradename or trademark
"Switchboard" in the United States on or in connection with the Switchboard Site
(the "Cessation Event"), it being understood, however, that CBS shall have the
sole right and power to approve the substitute tradename and/or trademark to be
used.  In the event that CBS fails to approve the substitute tradename and/or
trademark within the 30-day period prescribed, then upon the expiration of such
30-day period, CBS shall submit a tradename proposal with three (3) alternate
tradenames which appear to be available for the Company's use on the Switchboard
Site in the United States based on trademark searches

                                       4

Exchange Commission. Asterisks denote omissions.)


conducted by CBS, for the Company's approval, which approval is to be given
within ten (10) days of such submission. For the avoidance of doubt, CBS does
not and will not make any representation or warranty with respect to the
availability of any alternate name provided to Switchboard by CBS for use on the
Switchboard Site. Switchboard shall thereafter promptly apply for registration
of such trademark. In the event that during the application process, Switchboard
is advised in writing by its outside trademark counsel that such trademark does
not appear to be available for registration by Switchboard in connection with
the Switchboard Site or Switchboard is notified, in writing, that such
registration is denied, the foregoing process for determining a new trademark
shall begin again and the parties agree to work together in good faith to
endeavor to agree on a new trademark for the Switchboard Site in accordance with
this Section 2.3(a) or sooner, if reasonably practicable.

          (b) in the event the Switchboard Site is not operational for a 48-hour
period until it becomes operational in a manner substantially consistent with
the normal operation of the Switchboard Site prior to the initial disruption of
service.

     2.4  CBS will use its good faith efforts to suspend or withdraw advertising
and promotion upon receipt of a written request from Switchboard setting forth
Switchboard's reasonable belief that a continuation of such advertising and
promotion would be detrimental to CBS, Switchboard or the Switchboard Site.

     2.5  CBS shall have the right, but not the obligation, to sell advertising
space on the Switchboard Site, any Co-Branded Interface and any Vertical Guide.
In connection with CBS's right to sell such advertising, CBS will (i) include
the Switchboard Site, Co-Branded Interfaces and Vertical Guides in its CBS PLUS
advertising sales programs, (ii) designate an individual or group of individuals
to (A) work with Switchboard, at Switchboard's request, to develop a commission
structure (payable by Switchboard) and plan designed to motivate CBS sales
personnel to sell advertising on the Switchboard Site, Co-Branded Interfaces and
Vertical Guides and (B) establish a process regarding allocation of available
advertising inventory on the Switchboard Site, Co-Branding Interface and
Vertical Guides, and (iii) comply with Switchboard's advertising content
policies, the current version of which is attached hereto as Exhibit E, as well
                                                             ---------
as any applicable CBS advertising policies.  In effecting ad sales, CBS will
have the right to bundle inventory relating to the Switchboard Site, Co-Branded
Interfaces and Vertical Guides with television, radio, cable and billboard
inventory.  CBS will be entitled to receive from Switchboard a [**]%
commission with respect to advertising sold by CBS on the Switchboard Site, any
Co-Branded Interface and any Vertical Guide.


3.  LINKS TO AND INTEGRATION OF SWITCHBOARD CONTENT

     3.1  During the Term, hyperlinks to Co-Branded Interfaces for the purpose
of allowing CBS Users access to each of the Switchboard Directories shall be
placed on the home page of each of the CBS Sites. Such hyperlinks shall be in a
form as mutually agreed and shall be labeled, "find a person," "find a
business," and "find an e-mail address," or other mutually agreed designations.
Such hyperlinks shall be at least as large and prominently placed as any

                                       5
<PAGE>

other third party hyperlink, logo, or icon on the web pages on which they
appear. In addition, hyperlinks shall be placed Above the Fold on each Co-
Branded Interface for the purpose of allowing users to access the CBS Site or
CBS Associated Site related to such Co-Branded Interface.

     3.2  Notwithstanding anything to the contrary herein, Switchboard
acknowledges and agrees that the performance by CBS of any obligation pursuant
to this Agreement as it relates to any CBS Site is subject to any agreement or
condition existing as of the date hereof which could reasonably restrict or
prohibit CBS's ability to perform such obligation.  CBS agrees that (i) it will
avail itself of any contractual right it may have to terminate such agreement or
condition without the incurrence of any penalty, interest or damages thereunder,
(ii) it will perform such obligation as soon as practicable upon the expiration
or termination of such agreement or condition and (iii) in no event will CBS
agree to modify, extend or renew such agreement or condition.

     3.3  During the Term, CBS shall use good faith and commercially reasonable
efforts to try to obtain similar placement and implementation of hyperlinks on
each of the CBS Associated Sites to Co-Branded Interfaces for the purpose of
allowing CBS Users access to each of the Switchboard Directories, as set forth
in Section 3.1 with respect to CBS Sites.

     3.4  On an ongoing basis throughout the Term, the parties shall work
together in good faith to evaluate and agree upon additional opportunities to
integrate features and functionality from the Switchboard Site into the CBS
Sites, including but not limited to the Switchboard Directories, through links
in appropriate areas of such CBS Sites.  The goal of such mutual integration
effort shall be to enhance the content of the applicable CBS Sites and to
increase the traffic (page views) to the Switchboard Site.  By way of example
and not limitation, the CBS Sites may provide links from their local content
areas to vertical business guides, local directories, or topical or local
message boards featured on the Switchboard Site.  All traffic from links
established pursuant to this Section 3.4 shall be attributed to the Switchboard
Site.  The parties may meet to evaluate and discuss such integration
opportunities on a regular basis, but no less frequently than every six (6)
months.

     3.5  Through the hyperlinks referenced in Sections 3.1  3.3, CBS Users may
initiate queries to, and access content from, the Switchboard Site only through
a Co-Branded Interface.  Each page of a Co-Branded Interface shall be subject to
the approval of CBS and shall feature equal co-branding of CBS and Switchboard.
Except for the co-branding, each page of a Co-Branded Interface shall have the
design and "look and feel" of the applicable CBS Site or CBS Associated Site,
and the features and content of the Switchboard Site, except to the extent that
such features or content are supplied by third parties pursuant to contracts
that preclude their display through the Co-Branded Interface.  All pages of the
Co-Branded Interface shall be hosted on Switchboard's servers.  CBS shall pay
Switchboard a co-branding fee of Two Thousand Dollars ($2,000) for the completed
development of Co-Branded Interfaces for each CBS Site up to a maximum of one
hundred and fifty (150) web sites.  Fees for Co-Branded Interfaces for
additional web sites shall be as mutually agreed.

4.   DEVELOPMENT AND INTEGRATION BY SWITCHBOARD

     4.1  On an ongoing basis throughout the Term, the parties shall work
together in good faith to evaluate and agree on opportunities to integrate local
content from the www.cbs.com web site into the Switchboard Site through links in
appropriate areas of the Switchboard Site.  The goal of such mutual integration
effort shall be to enhance the content of the Switchboard Site and to increase
the traffic (page views) to the www.cbs.com web site.  By way of example and not
limitation, the Switchboard Site may link to local content from the www.cbs.com
web site from the "What's Nearby(TM)," web-searching interfaces, or local or
topical bulletin boards of the Switchboard Site.  All traffic from links
established pursuant to this Section 4.1 shall be attributed to the www.cbs.com
web site.  The parties shall discuss and evaluate such integration opportunities
at meetings scheduled in accordance with Section 3.4.

     4.2  The parties shall work together in good faith to identify appropriate
subject or category areas for the development by Switchboard of Vertical Guides
for CBS Sites and/or CBS Associated Sites.  Switchboard will develop, activate
and maintain such Vertical Guides, in a form reasonably satisfactory to CBS, as
soon as practicable after the appropriate subject or category areas have been
identified.  Such Vertical Guides shall include mutually agreed content and/or
features from the CBS Sites and from the Switchboard Site.  Content or features
from the Switchboard Site are to include, without limitation, category-specific
business listings, Display Ads, topical web site listings, maps and directions,
and/or "What's Nearby(TM)" content.  CBS shall assist Switchboard in integrating
any mutually agreed content from the CBS Sites into the Vertical Guides.  All
Vertical Guides developed by Switchboard hereunder shall feature the equal co-
branding of CBS and Switchboard.  All Vertical Guides shall be hosted on
Switchboard's servers.

     4.3  Content from the Switchboard Site included in any Vertical Guide shall
be updated as such information is updated on the Switchboard Site, except that,
unless otherwise mutually agreed, Display Ads or web sites featured in the
Yellow Pages Directory may not appear in the Vertical Guide unless the
advertiser has purchased distribution in such Vertical Guide.  Switchboard shall
not be responsible for updating content appearing in the Vertical Guides from
the CBS Sites or CBS Associated Sites except to the extent that such updates are
provided by CBS to Switchboard for such express purpose in a form reasonably
satisfactory to Switchboard.

     4.4  CBS shall maintain links from the appropriate CBS Sites to the
applicable Vertical Guides.  Switchboard may at its election provide links to
the Vertical Guides from the Switchboard Site.

     4.5  Switchboard shall develop such mutually agreed Vertical Guides for CBS
Sites at no charge.  Vertical Guides developed for CBS Associated Sites shall be
subject to mutually agreed terms that may include development or other fees and
mutually agreed branding.

(Confidential Materials omitted and filed separately with the Securities and
Exchange Commission. Asterisks denote omissions.)



     4.6  Switchboard shall retain all right, title and interest in the Vertical
Guides created by Switchboard hereunder, as the same may be updated from time to
time, and all content and intellectual property therein, except for content,
including without limitation, trademarks and logos, originating from the CBS
Sites or CBS Associated Sites.

     4.7  As of the Effective Date, Switchboard is engaged in the business of
selling Web Site Services to merchants, including distribution of merchants' web
sites on the Switchboard Site as well as on certain third party web sites as
agreed to by the merchant.  During the Term, for as long as Switchboard
continues to sell Web Site Services to new accounts, Switchboard shall market,
promote, and offer to "qualifying merchants" the right to purchase distribution
of links to their web sites from their Display Ads in the appropriate Vertical
Guides on the CBS Sites.  Switchboard may elect to offer such distribution as
part of a package of options that may or may not include distribution on other
third party web sites.  For the purposes of this Section, "qualifying merchants"
shall mean merchants within subjects or categories which are mutually agreed by
CBS and Switchboard to be appropriate for each Vertical Guide.

     4.8  Notwithstanding anything to the contrary set forth in this Agreement,
the rights and obligations of Switchboard and CBS set forth herein, including,
without limitation, those set forth in Sections 3 and 4, shall be subject to and
governed by the terms and provisions of the License Agreement (specifically
excluding Section 1 (Definitions), Section 5 (Warranties; Representations;
Indemnities), Section 6.4 (Limitation of Liability), Section 6 (Remedies) and
Section 7 (General) of the License Agreement) which is incorporated herein by
reference as if fully set forth herein.

5.   COMPENSATION

     5.1  In consideration of the rights herein granted, Switchboard shall pay
CBS [**]% of the Net Advertising Revenues derived from the sale of
advertising on the Co-Branded Interfaces or Vertical Guides during the Term.
Payments made to CBS pursuant to this Section 5.1 shall be in addition to any
payments due or owing to CBS pursuant to Section 2.5.

     5.2  Switchboard will compute Net Advertising Revenues as of each March 31,
June 30, September 30 and December 31 for the prior three (3) months.  Within
forty-five (45) days after the calendar quarterly period concerned, Switchboard
will send CBS a statement covering those sums and will pay CBS any Net
Advertising Revenues due.  Acceptance by CBS of any statement or payment shall
not preclude CBS from challenging the accuracy thereof.

     5.3  Switchboard will maintain accurate books and records that report the
sales of advertising on the Co-Branded Interfaces or Vertical Guides.  CBS may,
at its own expense, examine and copy those books and records, as provided in
this Section 5.3.  CBS may make such an examination for a particular statement
within three (3) years after the date such statement is sent by Switchboard to
CBS.  (Switchboard will be deemed conclusively to have sent CBS the statement
concerned on the date prescribed in Section 5.2, unless CBS notifies

                                       8
<PAGE>

Switchboard otherwise with respect to any statement, within thirty (30) days
after that date.) CBS may make those examinations only during Switchboard's
usual business hours, and at the place where it keeps the books and records.
Such books and records shall be kept at the address set forth herein for the
provision of notices to Switchboard, unless otherwise notified. CBS will be
required to notify Switchboard at least ten (10) days before the date of planned
examination.

6.   TERM

     6.1  This Agreement shall commence on the Effective Date and shall remain
in full force and effect for an initial period of seven (7) years, unless
earlier terminated as provided herein. After the initial term, this Agreement
may be renewed for successive one-year periods upon the mutual written agreement
of the parties. The initial term and any renewal terms, including the extension
provided for in Section 6.2 below, shall be collectively referred to herein
as the "Term."

     6.2  Notwithstanding the foregoing, upon the termination of the initial
period of this Agreement, this Agreement shall automatically be extended for one
additional year in the event that Switchboard elects to defer, in accordance
with Section 2.1(a), up to four million nine hundred thousand dollars
($4,900,000) of advertising and promotional value attributable to year seven (7)
of the initial period.

7.   WARRANTIES, REPRESENTATIONS AND COVENANTS

     7.1  (a)  CBS represents and warrants that:

               (i)     it has full power and authority to enter into and fully
          perform this Agreement; and

               (ii)    this Agreement has been duly authorized and is
          enforceable in accordance with its terms.

          (b)  Each of Banyan and Switchboard represents and warrants that:

               (i)     it has full power and authority to enter into and fully
          perform its obligations under this Agreement;

               (ii)    this Agreement has been duly authorized and is
          enforceable in accordance with its terms; and

               (iii)   the Switchboard Site is free of defects which would
          interrupt or interfere with the intended purpose thereof, including
          without limitation, (A) any malfunctions or other usage problems
          resulting from or in connection with the "Year 2000 Problem" (i.e.,
          the year 2000 (and later years) as distinct from the years 1900
          through 1999 (and earlier years)), and (B) "bugs" or "viruses."

                                       9
<PAGE>

          For the purposes of this paragraph, defects will be deemed to
          "interrupt or interfere with the intended purpose" of the Switchboard
          Site if they result in the failure to respond to user queries in a
          manner consistent with the normal operation of the Switchboard Site
          which shall have been maintained in a manner consistent with
          Switchboard's performance standards with respect to the Switchboard
          Site as set forth in Section 7.1(c)(iii).

          (c)  Switchboard covenants that:

               (i)     at all times during the Term, it will comply with all
          applicable federal, state and local laws;

               (ii)    at all times during the Term, the Switchboard Site and
          each Co-Branded Interface will be maintained in a professional manner
          consistent with industry standards; and

               (iii)   it will use its reasonable best efforts to adhere to the
          following performance standards:

                       (A)   to maintain the availability of the Switchboard
               Site and the Co-Branded Interfaces seven (7) days a week, twenty-
               four (24) hours a day, except during periods of scheduled
               maintenance;

                       (B)   to maintain competitive standards of quality and
              ease of use of its directory services with similar services
              offered by the top two third-party leading Internet-based
              directory services;

                       (C)   there shall be a maximum five (5) second response
               time for 90% of all directory searches of the Switchboard Site or
               any Co-Branded Interface as measured by Switchboard's servers.
               The response time measures the time a user request is received by
               the Switchboard server to the time the response to such request
               leaves the Switchboard server;

                       (D)   the Switchboard Site and Co-Branded Interfaces as
               displayed to users shall have at least 97% uptime over a twelve
               (12) month period, excluding events of an extraordinary nature
               which are beyond the control of Switchboard; and

                       (E)   Switchboard shall provide CBS with a contact for
               support of issues related to the Switchboard Site. Such contact
               shall be available to CBS seven (7) days a week, twenty-four (24)
               hours a day for emergency support.

<PAGE>

               (iv) the Switchboard Site and each Co-Branded Interface
          shall be free of defects which would interrupt or interfere with the
          intended purpose thereof, including without limitation, (A) any
          malfunctions or other usage problems resulting from or in connection
          with the "Year 2000 Problem" (i.e., the year 2000 (and later years) as
          distinct from the years 1900 through 1999 (and earlier years)), and
          (B) "bugs" or "viruses."  For the purposes of this paragraph, defects
          will be deemed to "interrupt or interfere with the intended purpose"
          of the Switchboard Site or Co-Branded Interface if they result in the
          failure to respond to user queries in a manner consistent with the
          normal operation of the Switchboard Site or Co-Branded Interface.

8.   INDEMNIFICATION

     8.1  Switchboard and, subject to Section 8.4, Banyan, shall, jointly and
severally, indemnify CBS and its respective affiliates and their respective
officers, directors, employees, stockholders, agents and representatives
against, and hold them harmless from, any loss, liability, claim, damage or
expense, including reasonable legal fees and expenses ("Losses") arising from,
in connection with or otherwise with respect to any breach of any representation
or warranty of Banyan or Switchboard or covenant of Switchboard contained in
this Agreement.

     8.2  CBS shall indemnify Switchboard and its respective affiliates and
their respective officers, directors, employees, stockholders, agents and
representatives against, and hold them harmless from, any Losses arising from,
in connection with or otherwise with respect to any breach of any
representation, warranty or covenant of CBS contained in this Agreement.

     8.3  The amount of any Loss for which indemnification is provided under
this Section 8 shall be calculated net of any amounts actually recovered by the
indemnified party under insurance policies with respect to such Loss and shall
be (i) increased to take account of net tax cost incurred by the indemnified
party arising from the receipt of indemnify payments hereunder (grossed up for
such increase) and (ii) reduced to take account of any net tax benefit realized
by the indemnified party arising from the incurrence or payment of any such
Loss.  In computing the amount of any such tax cost or tax benefit, the
indemnified party shall be deemed to recognize all other items of income, gain,
loss deduction or credit before recognizing any item arising from the receipt of
any indemnity payment hereunder or the incurrence or payment of any indemnified
Loss.

     8.4  Notwithstanding anything to the contrary in this Agreement, Banyan's
indemnification obligations hereunder with respect to the covenants of
Switchboard and the representation and warranty in Section 7.1(b)(iii) shall
terminate upon the earlier to occur of:

          (a) the first business day after the second anniversary of the date of
this Agreement when Banyan beneficially owns or controls, directly or
indirectly, shares of Common Stock representing less than a majority of the
total voting power; and

                                       11
<PAGE>

(Confidential Materials omitted and filed separately with the Securities and
Exchange Commission. Asterisks denote omissions.)



          (b) the first business day after any person or entity beneficially
owns or controls, directly or indirectly, shares of the Common Stock
representing more voting power (based on then-outstanding shares) than those
beneficially owned or controlled, directly or indirectly, by Banyan

provided, however, that Banyan's indemnification obligations shall not terminate
pursuant to this Section with respect to an item as to which CBS has, before the
occurrence of either of the events set forth above, previously made a claim by
delivering a notice of such claim (stating in reasonable detail the basis for
such claim) pursuant to Section 8.5 to Banyan.  For purposes of performing the
calculation of beneficial ownership and control referred to in the preceding
sentence, neither Banyan nor CBS shall be deemed to beneficially own or control
shares solely as a result of the existence of the Voting Agreement.

     8.5  In order for the indemnified party to be entitled to any
indemnification provided for under this Agreement in respect of, arising out of
or involving a claim made by any person against the indemnified party, the
indemnified party shall:  (i) promptly notify the indemnifying party of the
claim; (ii) allow the indemnifying party to direct the defense and settlement of
such claim with counsel of the indemnifying party's choosing; and (iii) provide
the indemnifying party, at the indemnifying party's expense, with information
and assistance that is reasonably necessary for the defense and settlement of
the claim.  The indemnified party reserves the right to retain counsel, at the
indemnified party's sole expense, to participate in the defense of any such
claim.  The indemnifying party shall not settle any such claim or alleged claim
without first obtaining the indemnified party's prior written consent, which
consent shall not be unreasonably withheld, if the terms of such settlement
would adversely affect the indemnified party's rights under this Agreement or
otherwise.  If the indemnifying party assumes the defense and settlement of the
claim as set forth above, then the indemnifying party's only obligation is to
satisfy the claim, judgment or approved settlement.

     8.6  (a)  IN NO EVENT SHALL SWITCHBOARD OR BANYAN, ON THE ONE HAND, AND
CBS, ON THE OTHER HAND, BE LIABLE TO ONE ANOTHER, OR TO ANY PERSON CLAIMING
THROUGH SWITCHBOARD OR BANYAN, ON THE ONE HAND, OR CBS, ON THE OTHER HAND, FOR
ANY CONSEQUENTIAL, INCIDENTAL, SPECIAL, OR INDIRECT DAMAGES, OR FOR ANY LOSS OF
PROFITS OR SALES OR LOSS OF OR DAMAGE TO DATA, REGARDLESS OF THE FORM OF SUCH
ACTION, WHETHER IN CONTRACT, TORT, OR OTHERWISE, EVEN IF ANY OF SWITCHBOARD OR
BANYAN, OR CBS, AS THE CASE MAY BE, HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES OR LOSS.

          (b) EXCEPT FOR (1) SWITCHBOARD'S AND CBS'S OBLIGATIONS TO MAKE ANY
PAYMENT EXPRESSLY REQUIRED BY THE TERMS OF THIS AGREEMENT; OR (II) CBS'S
OBLIGATION TO PROVIDE [**] PROMOTIONAL VALUE IN ACCORDANCE WITH THIS AGREEMENT,
THE MAXIMUM LIABILITY OF CBS, ON THE ONE HAND, AND OF SWITCHBOARD AND BANYAN, IN
THE AGGREGATE, ON THE OTHER HAND, UNDER THIS AGREEMENT AND THE COMMON STOCK AND
WARRANT PURCHSE AGREEMENT SHALL BE LIMITED TO THE AMOUNT SPECIFIED IN THE
FOLLOWING TABLE, SUBJECT TO THE PROVISOS SET FORTH BELOW IN THIS SECTION 8.6(b):

          PRIOR TO THE FIRST ANNIVERSARY OF
          THE DATE OF THIS AGREEMENT                            [**]

          ON OR AFTER THE FIRST ANNIVERSARY

PROVIDED, HOWEVER, THAT IF PARTIES ENTITLED TO INDEMNIFICATION UNDER SECTION 8.1
OF THIS AGREEMENT SUFFER LOSSES AS A RESULT OF A BREACH OF ANY REPRESENTATION OR
WARRANRY OF SWITCHBOARD OR BANYAN CONTAINED HEREIN IN AN AMOUNT WHICH EXCEEDS

AGGREGATE LIABILITY OF SWITCHBOARD AND BANYAN FOR THE SUM OF ALL LOSSES UNDER
THIS SECTION 8 AND UNDER THE COMMON STOCK AND WARRANT PURCHASE AGREEMENT IN A
CIRCUMSTANCE WHRE THE IMMEDIATELY FOREGOING PROVISO CLAUSE APPLIES SHALL IN NO

9.  REMEDIES

     9.1  CBS shall have the right to terminate this Agreement if (any of the
following occurs):

                                       12
<PAGE>

          (a)  Either Switchboard or Banyan breaches any material term or
condition of:

               (i)   this Agreement and has failed to cure such breach within
     thirty (30) days after written notice of such breach from CBS (the
     foregoing cure period will not apply where a specific cure period is
     provided herein); and/or

               (ii)  the Common Stock and Warrant Purchase Agreement, dated June
     1, 1999, by and among Switchboard, Banyan and CBS (the "Common Stock and
     Warrant Purchase Agreement") or any other Ancillary Agreement (as such term
     is defined in the Common Stock and Warrant Purchase Agreement) and has
     failed to cure such breach within thirty (30) days after written notice of
     such breach from CBS (the foregoing cure period will not apply where a
     specific cure period is provided herein);

provided, however, that CBS's right to terminate this Agreement pursuant to this
Section shall not apply to a breach by Switchboard or Banyan of the
representation and warranty set forth in Section 7(b)(iii) of this Agreement and
the representation and warranty set forth in Section 3.12(f) of the Common Stock
and Warrant Purchase Agreement.

          (b)  Switchboard:  (i) becomes insolvent or unable to pay its debts as
they mature or makes an assignment for the benefit of its creditors; (ii) is the
subject of a voluntary petition in bankruptcy or any voluntary proceeding
relating to insolvency, receivership, liquidation, or composition for the
benefit of creditors, if such petition or proceeding is not dismissed within
sixty (60) days of filing; (iii) becomes the subject of any involuntary petition
in bankruptcy or any involuntary proceeding relating to insolvency,
receivership, liquidation, or composition for the benefit of creditors, if such
petition or proceeding is not dismissed within sixty (60) days of filing; or
(iv)  is liquidated or dissolved.

          (c)  Switchboard issues to a CBS Competitor or actively participates
in the acquisition by a CBS Competitor, in any one transaction or series of
transactions, of a number of voting securities of Switchboard such that after
such issuance or acquisition or series of issuances or acquisitions, such CBS
Competitor beneficially owns or controls, directly or indirectly, nine percent
(9%) or more of the outstanding shares of Common Stock or nine percent (9%) or
more of the total voting power of Switchboard.

               (i) Notwithstanding the foregoing however, the provisions of this
     Section 9.1(c) shall not apply to a stockholder of Switchboard who
     beneficially owns or controls, directly or indirectly, nine percent (9%) or
     more of the outstanding shares of Common Stock or nine percent (9%) or more
     of the total voting power of Switchboard, on an "as converted" basis, on
     the day prior to the date of this Agreement until such stockholder
     beneficially owns or controls, directly or indirectly, fifteen percent
     (15%) or more of the outstanding shares of Common Stock or fifteen percent
     (15%) or more of the total voting power of Switchboard and such stockholder
     is a CBS Competitor.

                                       13
<PAGE>

               (ii) The parties hereby agree that Switchboard or Banyan may give
     CBS confidential written notice of its intent to enter into an agreement
     which would cause a stockholder to beneficially own or control, directly or
     indirectly, nine percent (9%) or more of the outstanding shares of Common
     Stock or nine percent (9%) or more of the total voting power of
     Switchboard, together with a description of the party with whom Switchboard
     or Banyan intends to effect such a transaction, for the purpose of
     ascertaining CBS's opinion whether, as of the date of the notice, such
     party is a CBS Competitor.  CBS shall have five (5) days from the receipt
     of such notice to respond to Switchboard or Banyan.  CBS's opinion shall be
     based solely on the information provided to CBS in the notice and CBS shall
     have no independent duty whatsoever to investigate or inquire further.  No
     opinion provided by CBS hereunder is or shall be deemed to be a waiver of
     any right of CBS pursuant to this Section 9.

          (d)  Any CBS Competitor (other than a CBS Competitor who acquired
shares of Switchboard capital stock directly from CBS) beneficially owns or
controls, directly or indirectly, fifteen percent (15%) or more of the then-
outstanding shares of common stock of Switchboard or fifteen (15%) or more of
the total voting power of Switchboard.

          (e)  Switchboard discontinues using the "Switchboard" mark or another
mutually agreed upon trademark in the United States (for any reason other than a
Cessation Event, or for no reason) and, within a reasonable time thereafter,
Switchboard does not establish a substitute mark acceptable to CBS in its sole
discretion, provided that if the substitute mark proposed by Switchboard is not
acceptable to CBS, CBS shall have submitted for Switchboard's approval a list of
three (3) proposed alternate trademarks which appear to be available for
Switchboard's use on the Switchboard Site in the United States based on
trademark searches conducted by CBS, and Switchboard has failed to approve any
such proposed trademarks within ten (10) days of such submission.  For the
avoidance of doubt, CBS does not and will not make any representation or
warranty with respect to the availability of any alternate name provided to
Switchboard by CBS for use on the Switchboard Site.

          (f)  The termination (other than by reason of a breach by CBS) or
expiration of the License Agreement.

          (g)  The Switchboard Site ceases to operate for (i) a consecutive
period of ten (10) days, or (ii) more than two (2) consecutive hours per week
over a sixty (60) day period; provided that such operational failure is not
attributable to failures beyond Switchboard's reasonable control which also
affect multiple third-party web sites on the Internet in a similar manner.

          (h)  For purposes of this Section 9.1: (i) the term "beneficial
ownership" shall have the meaning set forth in Section 13(d) of the Securities
Act of 1933, as amended, and the rules and regulations promulgated thereunder;
(ii) the term "total voting power" shall mean at any time, the total number of
votes that may be cast in the election of directors of Switchboard at any

Exchange Commission. Asterisks denote omissions.)



term "voting securities" shall mean the Common Stock and any other securities
issued by Switchboard having the power to vote in the election of directors of
Switchboard, including without limitation any securities having such power only
upon the occurrence of a default or any other extraordinary contingency.

     9.2  Switchboard shall have the right to terminate this Agreement if CBS
breaches any material term or condition of this Agreement or the License
Agreement, and has failed to cure such breach within thirty (30) days after
receipt of written notice from Switchboard of such breach.

     9.3 Notwithstanding anything to the contrary set forth in this Agreement,
[**] in the event of a proposed termination of this Agreement pursuant to
Section 9.1(a) or Section 9.2, the terminating party shall not be entitled to
terminate this Agreement pursuant to Section 9.1(a) or Section 9.2 in the event
that the non-terminating party elects to commence an Arbitration Proceeding (as
defined below) unless (1) the sole arbitrator in such Arbitration Proceeding has
determined that (x) the non-terminating party is in breach of a term or
condition of this Agreement, (y) such breach has not been cured withing thirty
(30) days after written notice of such breach from the terminating party and (z)
the breached term or condition is a material term or condition (it being agreed
that a term or condition will not be found to be material unless the terminating
party has suffered, or would reasonably be expected to suffer more than an
insignificant amount of harm (except with respect to the use of the CBS Marks
(as defined in the License Agreement) in a manner which is not permitted under
the License Agreement which the parties agree shall always be material without
taking into consideration and degree of harm) as a result of breach of such term
or condition and (2) the non-terminating party fails to cure such breach within
five (5) business days after receipt of the arbitrator's finding referred to in
clause (1). "Arbitration Proceeding" shall mean a proceeding conducted in
accordance with the following rules:

          (i)   such proceeding is commenced by the non-terminating party,
within twenty (20) days of receipt by it of a written notice of breach from the

state judge or a member of the CPC Panel of Distinguished Neutrals of the CPR
Institute for Dispute Resolution and who is not and has not been an afifliate,
employee, consultant, officer, director or stockholder of CBS, Banyan or
Switchboard) to conduct the proceeding;

          (ii)  within seven (7) days after the designation of the arbitrator,
the arbitrator and the parties shall meet, at which time each party shall be
required to set forth in writing al disputed issues, together with its proposed
resolution of the matter, all in reasonable and detail and containing such
supporting materials it may choose to submit;

          (iii) the arbitrator shall set a date for a hearing, which shall be no
later than ten (10) days after the submission of written proposals pursuant to
clause (ii) above, to discuss each of the issues identified by the parties. Each
party shall have the right to be represented by counsel. The arbitration shall
be governed by the Commercial Arbitration Rules of the American Arbitration
Association, provided however, that the Federal Rules of Evidence shall apply
with regard to the admissibility of evidence;

          (iv)  arbitrator shall rule on each of the three (3) matters on which
a finding is to be made with respect to each claim made by the terminating

Switchboard fails to approve one of CBS's proposed substitute tradenames within

Cessation Event and all rights and obligations of the parties hereunder shall
terminate.

     9.5  Each party may exercise its right to terminate pursuant to this

exercise by CBS of its rights under this Section 9 will limit CBS's remedies by
reason of Switchboard's or Banyan's default, CBS's rights to exercise any other
rights under this Section 9, or any of CBS's other rights.  No exercise by
Switchboard of its rights under this Section 9 will limit Switchboard's remedies

under this Section 9, or any of Switchboard's or Banyan's other rights.

promotion in accordance with Section 2 and such other related provisions has
terminated or expired and (ii) all of the parties' rights and obligations under

10.  MANDATORY TRANSFER

     10.1  CBS shall have the right (but not the obligation) in its sole
discretion to purchase Banyan's shares of Common Stock or require that such
shares of Common Stock be transferred to an independent trustee, as provided in
Section 10.2, within sixty (60) days after a CBS Competitor has directly or
indirectly acquired beneficial ownership of more than 30% of the outstanding
shares of the common stock, or securities representing, in the aggregate, more
than 30% of the  total voting power, of Banyan (or any parent entity
controlling Banyan), or all or substantially all of Banyan's assets (a "Banyan
Change of Control"), at a time when Banyan and its subsidiaries and parent
entities shall then own in the aggregate a number of shares of Common Stock
equal to at least ten percent (10%) of the outstanding shares of the Common
Stock, without the prior written consent of CBS (a "Triggering Event").  The
parties hereby agree that Banyan may give CBS confidential written notice of its
intent to enter into an agreement which would cause a Banyan Change of Control,
together with a description of the party with whom Banyan intends to effect such
a transaction.  CBS shall have twenty (20) days from receipt of such notice to
respond to Banyan in writing as to whether it would elect to trigger the
provisions of this Section 10 with respect to such potential Banyan Change of
Control.  If, and only if, CBS notifies Banyan in writing that it would not make
such election, CBS shall be deemed to have waived its right to trigger such
mandatory transfer provisions with respect to such potential Banyan Change of
Control.

     10.2  Upon the occurrence of a Banyan Change of Control, CBS may elect one
of the following within forty-five (45) days after written notice from Banyan
that a Banyan Change of Control has occurred:

          (a)  (i)  CBS may offer to purchase the shares of Common Stock   then
     held by Banyan and its subsidiaries and parent entities, and Banyan and its
     subsidiaries and parent entities shall be required to sell to CBS, such
     sale to occur no later than ten (10) days after Banyan's receipt of CBS's
     written offer to purchase such shares of Common Stock, at a purchase price
     for the shares of Common Stock held by Banyan and its subsidiaries and
     parent entities equal to the Fair Market Value of the Common Stock on the
     date of the Triggering Event.

               (ii) Notwithstanding the foregoing provisions of Section
     10.2(a)(i), if (y) any legal or regulatory requirements, including, without
     limitation, those imposed by the Hart-Scott-Rodino Antitrust Improvements
     Act of 1976, as amended, must be

                                       16
<PAGE>

     first satisfied prior to making such sale or (z) the Fair Market Value must
     be determined according to the terms of subsection (b) of the definition of
     Fair Market Value, then such sale shall be made within two (2) days of the
     satisfaction of such legal requirements or of the determination of the Fair
     Market Value of the Common Stock, as applicable.

               (iii)  Upon the date that payment is made for the shares of
     Common Stock held by Banyan and its subsidiaries and parent entities,
     Banyan and its subsidiaries and parent entities will have no further rights
     as a holder of such shares of Common Stock and Banyan and its subsidiaries
     and parent entities will forthwith cause all certificate(s) evidencing such
     shares of Common Stock to be surrendered to Switchboard or its transfer
     agent for cancellation and new certificates evidencing such shares of
     Common Stock will be promptly delivered to CBS.

          (b) CBS may require Banyan to transfer all shares of Common Stock then
held by Banyan and its subsidiaries and parent entities to an independent
trustee reasonably satisfactory to CBS, which trustee shall then dispose of such
shares of Common Stock formerly held by Banyan and its subsidiaries and parent
entities to purchaser(s) that is/are not CBS Competitor(s), subject to the
foregoing, in such a manner as such trustee shall determine with a view to
maximizing the sale price of the shares of Common Stock formerly held by Banyan
and its subsidiaries and parent entities, while disposing of such shares within
one year.  Upon such transfer, such trustee shall have sole voting and
dispositive control over such shares of Common Stock.  Banyan shall no longer be
entitled to nominate any directors to the Board of Directors of Switchboard and
Banyan shall cause all current directors nominated by Banyan who are directors
or officers or other employees of Banyan to resign from their positions as
members of Switchboard's Board of Directors and shall use its best efforts to
cause all current directors nominated by Banyan who are not directors or
officers or other employees of Banyan to resign from their positions as members
of Switchboard's Board of Directors.  Unless otherwise agreed in writing by CBS,
any trustee appointed pursuant to this Section 10.2(b) shall be a bank or trust
company incorporated or otherwise organized under the laws of the United States
or a state thereof and having a combined capital and surplus of at least
$100,000,000.  Any such trustee shall perform its duties upon customary terms
pursuant to documentation reasonably satisfactory to CBS, it being understood
and agreed that, without the prior written consent of CBS, no such trustee shall
vote any shares of Common Stock held by it at any meeting of the stockholders of
Switchboard or otherwise.

     10.3  "Fair Market Value" of the shares of Common Stock shall mean (i), for
any shares that are listed on a national securities exchange or authorized for
trading on the Nasdaq Stock Market or other automated quotation system, the
average of the closing prices for the five-day period ending on the date of the
Triggering Event, and (ii), for any other shares of Common Stock, such price as
is determined by a panel of appraisers (each of which is, or is an employee of,
an investment banking firm or appraisal firm of national reputation which has at
least three (3) years of experience in valuing technology or Internet
companies), one (1) chosen by CBS, one (1) chosen by Banyan and the third to be
chosen by the first two (2) appraisers.  If

                                       17
<PAGE>

the appraisers cannot reach agreement within thirty (30) days of the date of the
Triggering Event, then each appraiser shall deliver its appraisal within forty
(40) days of the Triggering Event and the appraisal which is neither the highest
nor the lowest shall constitute the Fair Market Value. In the event either CBS
or Banyan fails to choose an appraiser within thirty (30) days of the date of
the Triggering Event, then the appraisal of the sole appraiser shall constitute
the Fair Market Value. Each party shall bear the cost of the appraiser selected
by it and the cost of the third appraiser shall be borne one-half by each of CBS
and Banyan. In the event either CBS or Banyan fails to choose an appraiser, the
cost of the sole appraiser shall be borne one-half by each CBS and Banyan.

11.  INTELLECTUAL PROPERTY

     11.1  CBS agrees and acknowledges that Switchboard, its licensors or
advertisers own all right, title and interest in and to all patents, copyrights,
trademarks, trade secrets and other intellectual property rights in the
Switchboard Site, or any content or data displayed therein (other than content
or data provided by CBS hereunder), and any software provided to CBS in
connection with this Agreement.  Switchboard agrees and acknowledges that CBS,
its licensors or advertisers own all right, title and interest in and to all
patents, copyrights, trademarks, trade secrets and other intellectual property
rights in the CBS Sites, or any content or data displayed therein (other than
content or data provided by Switchboard hereunder).  Neither CBS nor Switchboard
shall take any action inconsistent with the ownership of either party or its
licensors nor attempt to register any such intellectual property in any
jurisdiction.

12.  CONFIDENTIALITY

     12.1  Switchboard and CBS agree and acknowledge that they may be required
to disclose to each other certain confidential information, including but not
limited to information concerning the other party's online services and web
sites, technology, software, tools, business, or plans for the future in
connection with any of the foregoing, information concerning customers,
suppliers, personnel and other business relationships, sales and marketing
plans, financial information and other confidential information, all of which
shall be deemed "Confidential Information" for the purposes of this Section if,
with respect to such information disclosed in tangible form, it is marked
"Confidential" or its equivalent, and if disclosed orally or visually, it is
identified as confidential at the time of disclosure.

     12.2  For a period of three (3) years from the date of receipt of any
Confidential Information hereunder, or in perpetuity with respect to source code
or related documentation, the receiving party agrees to protect the
confidentiality of the disclosing party's Confidential Information with at least
the same degree of care that it utilizes with respect to its own similar
proprietary information, but in no event less than a reasonable standard of
care, including without limitation agreeing:

          (a) Not to disclose or otherwise permit any other person or entity
access to, in any manner, the Confidential Information, or any part thereof in
any form whatsoever,

                                       18
<PAGE>

except that such disclosure or access shall be permitted to (i) an employee or
consultant of the receiving party requiring access to the Confidential
Information in the course of his or her employment or consulting services in
connection with this Agreement and who has agreed in writing to maintain the
confidentiality of the confidential information of third parties in the
receiving party's possession; or (ii) a director, legal advisor, or financial
advisor of the recipient party hereunder, provided that such parties are bound
to maintain the confidentiality of such information and provided further that
they are permitted to use such Confidential Information only for the purposes of
carrying out their fiduciary or other advisory responsibilities on behalf of the
party hereto from which it received such Confidential Information; and

          (b) Not to use the Confidential Information for any purpose other than
to carry out the purposes of this Agreement.

     12.3  Nothing in this Section 12 shall restrict the receiving party with
respect to information or date, whether or not identical or similar to that
contained in the Confidential Information, if such information or data:  (i) was
rightfully possessed by the receiving party before it was received from the
disclosing party; (ii) is independently developed by the receiving party without
reference to the disclosing party's information or data; (iii) is subsequently
furnished to the receiving party by a third party not under any obligation of
confidentiality with respect to such information nor data, and without
restrictions on use or disclosure; or (iv) is or becomes public or available to
the general public otherwise than through any act or default of the receiving
party.

13.  GENERAL

subject to the terms and conditions contained herein, the non-exclusive right
and license to use the CBS Marks together with the SWITCHBOARD mark in
connection with identifying, marketing and promoting the Switchboard Site but
only to the extent that CBS has the right to use the CBS Marks.  Nothing in this
Agreement grants Switchboard ownership or other rights in or to the CBS Marks,
except in accordance with and to the extent of this license.

    2.2   Switchboard's exercise of the rights granted herein shall conform to
the restrictions or requirements set forth in the CBS License Guidelines
(attached hereto as Exhibit "A"), as such License Guidelines may be amended or
revised from time to time by CBS, to reflect any changes in the (a) rules or

or policies of CBS or Switchboard.

<PAGE>

    2.3  During the term of this Agreement, any Content displayed on the
Switchboard Site shall be subject to any restrictions or requirements set forth
in the CBS License Guidelines.  Notwithstanding the foregoing, CBS shall have
the right to demand the withdrawal from the Switchboard Site of any Content (or
any link to Content) which in CBS's sole opinion conflicts with, interferes with
or is detrimental to CBS's interests, reputation or business or which might
subject CBS to unfavorable regulatory action, violate any law, infringe the
rights of any Person, or subject CBS to liability for any reason.  Upon notice
from CBS to withdraw the Content concerned, Switchboard shall cease using any
such Content on the Switchboard Site as soon as commercially and technically
feasible, but in any event within two (2) business days after the date of CBS's
notice.

     2.4  During the term of this Agreement, Switchboard shall not, without
CBS's prior written approval advertise, promote or market in any media now known
or hereafter developed, including the Internet, any CBS Competitor, except that:

         (a) Switchboard may display a Local Competitor Ad on the Switchboard
Site in response to a user's location-specific search for a business, provided
that: (i) such searched location is within the purview of a designated market
area ("DMA") which would permit the broadcast of such Local Competitor Ad; and
(ii) such Local Competitor Ad is displayed within the geographic parameters of
the user's search.  "Local Competitor Ad", in this paragraph, means any
advertisement for the product(s) or service(s) of a CBS Competitor which,
pursuant to CBS policy may be broadcast on a local CBS owned or affiliated
television or radio station (i.e. broadcast to a local audience) but which may

is no CBS owned or affiliated television or radio station in the DMA concerned,
then the applicable standard (with respect to the display of a Local Competitor
Ad on the Switchboard Site) shall be that of the nearest DMA to the searched
location.

         (b) Switchboard may promote a CBS Competitor in printed (i.e. hard
copy) press releases or marketing or promotional materials solely in connection
with the solicitation of merchants on a Competitor Merchant Roster.  "Competitor
Merchant Roster", in this paragraph, means the list of merchants targeted by a
CBS Competitor and Switchboard for the purpose of promoting the sale of local
merchant advertisements, websites and related services on the Switchboard Site.

         (c) In connection with the directory feature/function of the
Switchboard Site, Switchboard may display/include the name, address, email
address or phone number of a CBS Competitor.

         (d) In connection with the web search feature/function on the
Switchboard Site, Switchboard may display the website URL of a CBS Competitor.

    2.5  Upon expiration or termination of this Agreement, Switchboard shall
immediately cease all use of the CBS Marks in connection with the name and
operation of the Switchboard Site or otherwise.  In connection with the above,
Switchboard shall immediately remove or erase the CBS Marks from the Switchboard
Site as soon as commercially and technically practicable, given customary
Internet business practices, but in no event shall any such material remain on
the Switchboard Site more than five (5) days after expiration or termination, as
applicable, and at CBS's request, Switchboard shall furnish CBS with certified
evidence of such removal or erasure satisfactory to CBS.

(including any requirements/restrictions delineated in the CBS License
Guidelines), reasonably deemed necessary by CBS to protect CBS's tradename,
Marks or reputation.  All materials bearing the CBS Marks shall be subject to
CBS's prior written approval (subject to subparagraph 4.2(b) below).

         (b) In the event that during the term of this Agreement Switchboard
shall create any proprietary right in any CBS Marks, as a result of the exercise
by Switchboard of any right granted to it hereunder, such proprietary right
(excluding any proprietary right in any mark owned by or licensed by third
parties to Switchboard) shall immediately vest in CBS and Switchboard shall be

agreed-on tag language appearing at the end of each press release or the like
which language is non-contextual, shall be subject to CBS's prior approval.)

of the CBS Marks.  Approval by CBS shall not relieve Switchboard of any of its
warranties or obligations under this Agreement and, except as otherwise

                 between CBS Corporation and Switchboard Inc.)

                    CBS LICENSE GUIDELINES AND RESTRICTIONS
                    ---------------------------------------


I.  GENERAL

    1.  The Switchboard Site shall not include the following Content (nor
    establish links from the Site to the following Content): (i) cigarettes,
    (ii) hard liquor, (iii) massage parlors, (iv) abortion clinics, (v) firearms
    and ammunition, (vi) head shops, (vii) lotteries, (viii) gambling, (ix)
    sexually explicit content, (x) Content that contains profanity, (xi) Content
    that denigrates a particular group based on gender, race, creed, religion,
    sexual preference or handicap and (xii) any advertisements (covering a
    particular product, issue or service) proscribed by the CBS Television
    Network Advertising Guidelines attached hereto as Exhibit D ("Proscribed
    Content").

    2.  Notwithstanding anything to the contrary in this Agreement, including
    without limitation, the CBS License Guidelines and Restrictions, as same may
    be updated from time to time upon written notice to Switchboard, and any
    further requirements or restrictions which CBS may impose in accordance with
    its rights under this Agreement, the following shall not be deemed a breach
    of this Agreement:

         (a) In connection with the directory feature/function of the
         Switchboard Site, Switchboard's display/inclusion of the name, address,
         email address or phone number of a Person which is engaged in a
         business related to Proscribed Content;

         (b) Switchboard may display a Permissible Local Ad on the Switchboard
         Site in response to a user's location specific search for a business,
         provided that: (i) such searched location is within the purview of a
         designated market area ("DMA") which would permit the broadcast of such
         Permissible Local Ad; and (ii) such Permissible Local Ad is displayed
         within the geographic parameters of the user's search.  "Permissible
         Local Ads" in this paragraph means any advertisement for the product(s)
         or service(s) which, pursuant to CBS policy may be broadcast on a local
         CBS owned or affiliated television or radio station (i.e. broadcast to
         a local audience) but which would be deemed Proscribed Content if
         advertised on the CBS Television Network pursuant to CBS policy. If
         there is no CBS owned or affiliated television or radio station in the
         DMA concerned, then the applicable standard (with respect to the
         display of a Permissible Local Ad on the Switchboard Site) shall be
         that of the nearest DMA to the searched location.

                                      -15-
<PAGE>

         (c) In connection with the web search feature/function on the
         Switchboard Site, the display of web site URLs related to Proscribed
         Content (e.g., pornography), provided that, upon CBS's request in each
         instance, Switchboard shall place a warning page between the search
         page and the initial results page (based on mutually agreed-on
         keywords), which warning page alerts the viewer: (i) of the type of
         Content appearing in the upcoming pages (e.g., "adult language"); (ii)
         that the Switchboard Site is not the sender of the information; (iii)
         that by proceeding forward, the viewer has chosen to receive the
         information, (iv) that the viewer may choose not to proceed and (v) any
         other related notices that CBS may require (the "Warning Page"). CBS
         and Switchboard will consult each other on an ongoing basis with
         respect to the insertion of Warning Pages. (The foregoing paragraph
         shall not limit CBS's rights under paragraph 2.3 of this Agreement.)

         (d) If Switchboard links to an Internet website that exhibits
         Proscribed Content, provided that: (i) the Proscribed Content
         represents an insignificant portion or aspect of such website; and (ii)
         Switchboard derives no revenues or other financial benefit from such
         Proscribed Content.  For avoidance of doubt, "financial benefit from
         Proscribed Content" includes the realization (or accrual) of any
         revenue from page views of Proscribed Content or advertisements
         displayed on website pages containing Proscribed Content. The foregoing
         shall not be deemed an implied right to link to Content that violates
         any law or infringes the rights of any Person. (This subparagraph (d)
         shall not limit CBS's rights under paragraph 2.3 of this Agreement.)

         (e) Placement by Switchboard Site users of Proscribed Content on
         personal web pages, bulletin boards or other places on the Switchboard
         Site where users are permitted by Switchboard to place personal
         content, provided that Switchboard will remove any such Content if
         requested by any Person who claims its, his or her rights are being
         infringed.


II. TRADEMARKS

    Switchboard  shall place a trademark notice to be furnished by CBS on all
    items or materials utilizing CBS Marks.  CBS shall provide Switchboard with
    the manner, style and placement of such notice, which shall be deemed
    incorporated into this Section.


III.  CROSS-LINKS

    Except as set forth in Section I, paragraph 2. above, Switchboard  shall not
    establish any links from the Switchboard Site to, or authorize any links to
    the Switchboard Site from, any gambling,  pornography, obscenity Content or

                           WARRANT PURCHASE AGREEMENT
                           --------------------------


     This Warrant Purchase Agreement (this "Agreement") dated as of June 1, 1999
is entered into by and between Banyan Systems Incorporated, a Massachusetts
corporation (the "Company"), and CBS Corporation, a Pennsylvania corporation
(the "Purchaser").

     In consideration of the mutual promises and covenants contained in this
Agreement, the parties hereto agree as follows:

     1.   Sale of Securities.
          ------------------

          1.1  Securities.  Subject to the terms and conditions of this
Agreement, at the Closing (as defined below), Banyan will sell and issue to the
Purchaser, and the Purchaser will purchase from Banyan a warrant to purchase
250,000 shares of Common Stock, $.01 par value per share, of (the "Common

consideration set forth in Section 1.2 of this Agreement (the "Purchase Price").

          1.2  Purchase Price.  The Purchase Price is two hundred fifty thousand
dollars ($250,000) and shall be paid as set forth on Schedule 1.2 attached
hereto.

     2.   The Closing.
          -----------

          (a) The closing (the "Closing") of the sale and purchase of the
Warrant under this Agreement shall occur simultaneously with and at the same
place as the closing of the transactions contemplated by the Common Stock and
Warrant Purchase Agreement of even date herewith among Switchboard Incorporated,
Banyan and the Purchaser (the "Switchboard Purchase Agreement").  The date of
the Closing is hereinafter referred to as the "Closing Date."

          (b)  At the closing:

               (i)  Banyan shall deliver (or cause to be delivered) to the
     Purchaser the various certificates, instruments and documents required to
     be so delivered by Banyan pursuant to Section 7.2 of this Agreement.

               (ii)  The Purchaser shall deliver (or cause to be delivered) to
     Banyan the various certificates, instruments and documents required to be

     purchased at the Closing by the Purchaser, registered in the name of the
     Purchaser.

     3.   Representations of Banyan.  Except as disclosed by Banyan in Exhibit B
hereto, Banyan hereby represents and warrants to the Purchaser that the
statements contained in this Section 3 are true, complete and correct as of the
date of this Agreement.  Exhibit B shall be organized into sections
corresponding with the sections of this Section 3 and the disclosure in any
section of Exhibit B shall be deemed to qualify (i) the corresponding section of
this Section 3 and (ii) other sections of this Section 3 to the extent it is
clearly apparent (notwithstanding the absence of a specific cross reference)
from a reading of such disclosure that such disclosure is applicable to such
other sections.

          3.1  Organization and Standing.  Banyan is a corporation duly
organized, validly existing and in good standing under the laws of the
Commonwealth of Massachusetts and has the corporate power and authority to
conduct its business as presently conducted and as presently proposed to be
conducted by it and to enter into and perform this Agreement and to carry out
the transactions contemplated by this Agreement.

          3.2  Issuance of Warrant.  The issuance, sale and delivery of the
Warrant in accordance with this Agreement, and the issuance and delivery of the
shares of Common Stock issuable upon exercise of the Warrant (the "Warrant
Shares"), have been duly authorized by all necessary corporate action on the
part of Banyan, and all such Warrant Shares have been duly reserved for
issuance.  The Warrant Shares, when issued upon exercise of the Warrant
following payment of the exercise price therefor, will be duly and validly
issued, fully paid and nonassessable.

          3.3  Authority for Agreement; No Conflict.  The execution, delivery
and performance by Banyan of this Agreement, and the consummation by Banyan of
the transactions contemplated hereby has been duly authorized by all necessary
corporate action.  This Agreement has been duly executed and delivered by Banyan
and constitutes a valid and binding obligation of Banyan enforceable in
accordance with its terms, subject as to enforcement of remedies to applicable
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or
similar laws affecting generally the enforcement of creditors' rights and
subject to a court's discretionary authority with respect to the granting of a
decree ordering specific performance or other equitable remedies.  The execution
of and performance of the transactions contemplated by this Agreement and
compliance with its provisions by Banyan will not (a) conflict with or

                                      -2-
<PAGE>

violate any provision of the Articles of Organization or By-laws of Banyan, (b)
other than as may be required by the Hart-Scott-Rodino Antitrust Improvements
Act ("HSR Act"), require on the part of Banyan any filing with, or any permit,
authorization, consent or approval of, any court, arbitrational tribunal,
administrative agency or commission or other governmental or regulatory
authority or agency (each of the foregoing is hereafter referred to as a
"Governmental Entity"), (c) conflict with, result in a breach of, constitute
(with or without due notice or lapse of time or both) a default under, result in
the acceleration of, create in any party the right to accelerate, terminate,
modify or cancel, or require any notice, consent or waiver under, any contract,

mortgage for borrowed money, instrument of indebtedness, Security Interest (as
defined below) or other arrangement to which Banyan is a party or by which
Banyan is bound or to which its assets are subject, (d) result in the imposition
of any Security Interest upon any assets of Banyan or (e) violate any order,
writ, injunction, decree, statute, rule or regulation applicable to Banyan or
any of its properties or assets, other than any of the foregoing events listed
in clauses (c), (d) or (e) of this Section 3.3 that would not have a material
adverse effect on the business, assets or financial condition of Banyan (a
"Banyan Material Adverse Effect"). For purposes of this Agreement, "Security
Interest" means any mortgage, pledge, security interest, encumbrance, charge, or
other lien (whether arising by contract or by operation of law) other than (i)
mechanic's, materialmen's, and similar liens, (ii) liens arising under worker's
compensation, unemployment insurance, social security, retirement, and similar
legislation, (iii) liens on goods in transit incurred pursuant to documentary
letters of credit, and (iv) statutory liens with respect to current taxes not
yet due and payable.

          3.4  Governmental Consents.  Except as may be required by the HSR Act,
no consent, approval, order or authorization of, or registration, qualification,
designation, declaration or filing with, any Governmental Entity is required on
the part of Banyan in connection with the execution and delivery by Banyan of
this Agreement, the offer, issuance, sale and delivery of the Warrant, the
issuance and delivery of the Warrant Shares or the other transactions to be
consummated at the Closing, as contemplated by this Agreement, except such
filings as shall have been made prior to and shall be effective on and as of the
Closing and such filings required to be made after the Closing under applicable
federal and state securities laws, and except any filings that, if not made as
required, would not have a Banyan Material Adverse Effect. Based on the
representations made by the Purchaser in Section 4 of this Agreement, the offer
and sale of the Warrant to the Purchaser will be in compliance with applicable
federal and state securities laws.

          3.5  Reports and Financial Statements.  Banyan has previously
furnished to the Purchaser complete and accurate copies, as amended or
supplemented, of its (a) Quarterly Report on Form 10-Q for the fiscal quarter
ended March 31, 1999, as filed with the Securities and Exchange Commission, (the
"Commission"), and

                                      -3-
<PAGE>

(b) Annual Report on Form 10-K for the fiscal year ended December 31, 1998, as
filed with the Commission (such reports are collectively referred to herein as
the "Banyan Reports"). As of their respective dates, the Banyan Reports did not
contain any 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, in
light of the circumstances under which they were made, not misleading. The
audited financial statements and unaudited interim financial statements of
Banyan included in the Banyan Reports (i) comply in all material respects with
applicable accounting requirements and the published rules and regulations of
the Commission with respect thereto, (ii) have been prepared in accordance with
generally accepted accounting principles applied on a consistent basis
throughout the periods covered thereby (except as may be indicated therein or in
the notes thereto, and in the case of quarterly financial statements, as
permitted by Form 10-Q under the Securities Exchange Act of 1934, as amended),
and (iii) fairly present the consolidated financial condition, results of
operations and cash flows of Banyan as of the respective dates thereof and for
the periods referred to therein.

          3.6  Litigation.  There is no action, suit or legal proceeding, or
governmental inquiry or investigation, pending against Banyan, or, to Banyan's
knowledge, threatened against, Banyan which questions the validity of this
Agreement or the right of Banyan to enter into this Agreement.

          3.7  Absence of Certain Changes.  Except as disclosed in the Banyan
Reports, since December 31, 1998, there has been no material adverse change in
the business, assets or financial condition of Banyan, other than changes
occurring in the ordinary course of business.

          3.8  Undisclosed Liabilities.  Banyan has no liability (whether
absolute, accrued, contingent or otherwise) of a nature required by GAAP to be
shown on a balance sheet which is material to Banyan, except for (i) liabilities
reflected in the Banyan Reports, (ii) liabilities which have arisen since March
31, 1999 in the ordinary course of business and (iii) contractual liabilities
incurred in the ordinary course of business.

     4.     Representations of the Purchaser.  Except as disclosed by the
Purchaser in Exhibit B-3 hereto, the Purchaser hereby represents and warrants to
Banyan that the statements contained in this Section 4 are true, complete and
correct as of the date of this Agreement.  Exhibit B-3 shall be organized into
sections corresponding with the sections of this Section 4 and the disclosure in
any section of Exhibit B-3 shall be deemed to qualify (i) the corresponding
section of this Section 4 and (ii) other sections of this Section 4 to the
extent it is clearly apparent (notwithstanding the absence of a specific cross-
reference) from a reading of such disclosure that such disclosure is applicable
to such other sections.

          4.1    Investment.  The Purchaser is acquiring the Warrant and the
Warrant Shares for its own account for investment and not with a view to, or for
sale in connection with, any distribution thereof, nor with any present
intention of distributing or selling the same; and, except as contemplated by
this Agreement, the Purchaser has no present or contemplated agreement,
undertaking, arrangement, obligation, indebtedness or commitment providing for
the disposition thereof.  The Purchaser is an "accredited investor" as defined
in Rule 501(a) under the Securities Act of 1933, as amended (the "Securities
Act").

          4.2    Experience. The Purchaser is an investor in securities of
companies in the development stage and acknowledges that it is able to fend for
itself, can bear the economic risk of its investment and has such knowledge and
experience in financial or business matters that it is capable of evaluating the
merits and risks of the investment in the Warrant and the Warrant Shares.  The
Purchaser has been furnished with and has had access to such information as the
Purchaser considered necessary to make a determination as to the purchase of the
Warrant and the Warrant Shares.

          4.3    Organization and Standing.  The Purchaser is a corporation duly
organized, validly existing and in good standing under the laws of the
Commonwealth of Pennsylvania and has the corporate power and authority to
conduct its business as presently conducted by it and to enter into and perform
this Agreement and to carry out the transactions contemplated by this Agreement.

          4.4    Authority for Agreement; No Conflict.  The execution, delivery
and performance by the Purchaser of this Agreement, and the consummation by the
Purchaser of the transactions contemplated hereby and thereby, have been duly
authorized by all necessary corporate action.  This Agreement has been duly
executed and delivered by the Purchaser and constitutes a valid and binding
obligation of the Purchaser enforceable in accordance with its terms, subject as
to enforcement of remedies to applicable bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium or similar laws affecting generally the
enforcement of creditors' rights and subject to a court's discretionary
authority with respect to the granting of a decree ordering specific performance
or other equitable remedies.  The execution of and

                                      -5-
<PAGE>

performance of the transactions contemplated by this Agreement and compliance
with its provisions by the Purchaser will not (a) conflict with or violate any
provision of the Articles of Incorporation or By-laws of the Purchaser, (b)
other than as may be required by the HSR Act, require on the part of the
Purchaser any filing with, or any permit, authorization, consent or approval of,
any Governmental Entity, (c) conflict with, result in a breach of, constitute
(with or without due notice or lapse of time or both) a default under, result in
the acceleration of, create in any party the right to accelerate, terminate,
modify or cancel, or require any notice, consent or waiver under, any contract,
lease, sublease, license, sublicense, franchise, permit, indenture, agreement or
mortgage for borrowed money, instrument of indebtedness, Security Interest or
other arrangement to which the Purchaser is a party or by which the Purchaser is
bound or to which its assets are subject, (d) result in the imposition of any
Security Interest upon any assets of the Purchaser or (e) violate any order,
writ, injunction, decree, statute, rule or regulation applicable to the
Purchaser or any of its properties or assets, other than any of the foregoing
events listed in clause (c), (d) or (e) of this Section 4.4 that would not have
a material adverse effect on the ability of the Purchaser to perform its
obligations under this Agreement (a "Purchaser Material Adverse Effect").

          4.5    Governmental Consents.  Except as may be required by the HSR
Act, no consent, approval, order or authorization of, or registration,
qualification, designation, declaration or filing with, any Governmental Entity
is required on the part of the Purchaser in connection with the execution and
delivery by the Purchaser of this Agreement, except such filings as shall have
been made prior to and shall be effective on and as of the Closing, and except
any filings that, if not made as required, would not have a Purchaser Material
Adverse Effect.

          4.6  Litigation.  There is no action, suit or legal proceeding, or
governmental inquiry or investigation, pending against the Purchaser or, to the
Purchaser's knowledge, threatened against the Purchaser which questions the
validity of this Agreement or the right of the Purchaser to enter into this
Agreement, or which would have a Purchaser Material Adverse Effect.

     5.     Reservation of Common Stock. Banyan will at all times reserve and
keep available, solely for issuance and delivery upon the exercise of the
Warrant, such number of Warrant Shares and other stock, securities and property,
as from time to time shall be issuable upon the exercise of the Warrant.

     6.     Transfer of Warrant.  Neither the Warrant nor any interest therein
is transferable in any respect.

shall be true and correct in all respects as of such date), except in each case
for such failures of representations and warranties to be true and correct (i)
as the result of changes expressly contemplated by this Agreement, and (ii) that
would not have a Banyan Material Adverse Effect (it being agreed that the clause
(ii) shall be inapplicable to any portion of a representation and warranty which
already contains a Banyan Material

Adverse Effect or other materiality qualification or, if an entire

                                      -8-
<PAGE>

except in each case for such failures of representations and warranties to be
true and correct (i) as the result of changes expressly contemplated by this
Agreement, and (ii) that would not have a Purchaser Material Adverse Effect (it
being agreed that the clause (ii) shall be inapplicable to any portion of a

counsel substantially in form and substance of Exhibit D.

     8.   Indemnification
          ---------------

          8.1  Indemnification by Banyan.   Banyan shall indemnify the Purchaser
and its affiliates and their respective officers, directors, employees, agents
and representatives against, and hold them harmless from, any loss, liability,
claim, damage or expense (including reasonable legal fees and expenses)
("Losses"), actually incurred by them, as incurred (payable promptly upon
written request), arising from, in connection with or otherwise with respect to:

          (a) any breach of any representation or warranty of Banyan contained
in this Agreement or in the closing certificate delivered at the Closing
pursuant to Section 7.2(a); and

          (b) any breach of any covenant of Banyan contained in this Agreement.

          8.2  Indemnification by Purchaser.  The Purchaser shall indemnify
Banyan and its affiliates and their respective officers, directors, employees,
agents and representatives against, and hold them harmless from, any Losses,
actually incurred by them, as incurred (payable promptly upon written request),
arising from, in connection with or otherwise with respect to:

          (a) any breach of any representation or warranty of the Purchaser
contained in this Agreement or in the closing certificate delivered at the
closing pursuant to Section 7.3(a); and

          (b) any breach of any covenant of the Purchaser contained in this
Agreement.

                                      -9-
<PAGE>

          8.3  Calculation of Losses.  The amount of any Loss for which
indemnification is provided under this Section 8 shall be calculated net of any
amounts actually recovered by the indemnified party under insurance policies
with respect to such Loss and shall be (i) increased to take account of any net
tax cost incurred by the indemnified party arising from the receipt of indemnity
payments hereunder (grossed up for such increase) and (ii) reduced to take
account of any net tax benefit realized by the indemnified party arising from
the incurrence or payment of any such Loss.  In computing the amount of any such
tax cost or tax benefit, the indemnified party shall be deemed to recognize all
other items of income, gain, loss deduction or credit before recognizing any
item arising from the receipt of any indemnity payment hereunder or the
incurrence or payment of any indemnified Loss.

          8.4  Termination of Indemnification.  The obligations to indemnify and
hold harmless any party, pursuant to this Section 8, shall terminate upon the
second anniversary of the Closing Date; provided, however, that such obligations
to indemnify and hold harmless shall not terminate with respect to any item as
to which the person to be indemnified shall have, before such anniversary date,
previously made a claim by delivering a notice of such claim (stating in
reasonable detail the basis of such claim) pursuant to Section 8.5 to the party
to be providing the indemnification.

          8.5  Procedures.
               -----------

          (a) In order for a party (the "indemnified party"), to be entitled to
any indemnification provided for under this Agreement in respect of, arising out
of or involving a claim made by any person against the indemnified party (a
"Third Party Claim"), such indemnified party must notify the indemnifying party
in writing of the Third Party Claim promptly following receipt by such
indemnified party of written notice of the Third Party Claim; provided, however,
that failure to give such notification shall not affect the indemnification
provided hereunder except to the extent the indemnifying party shall have been
actually prejudiced as a result of such failure. Thereafter, the indemnified
party shall deliver to the indemnifying party, promptly following the
indemnified party's receipt thereof, copies of all notices and documents
(including court papers) received by the indemnified party relating to the Third
Party Claim and not also addressed to the indemnifying party.

          (b) If a Third Party Claim is made against an indemnified party, the
indemnifying party shall be entitled to participate in the defense thereof and,
if it so chooses, to assume the defense thereof with counsel selected by the
indemnifying party; provided, however, that such counsel is not reasonably
objected to by the indemnified party.  Should the indemnifying party so elect to
assume the defense of a Third Party Claim, the indemnifying party shall not be
liable to the indemnified party for any legal expenses subsequently incurred by
the indemnified party in connection with the defense thereof.  If the
indemnifying party assumes such defense, the

                                      -10-
<PAGE>

indemnified party shall have the right to participate in the defense thereof and
to employ counsel, at its own expense, separate from the counsel employed by the
indemnifying party, it being understood that the indemnifying party shall
control such defense. The indemnifying party shall be liable for the fees and
expenses of counsel employed by the indemnified party for any period during
which the indemnifying party has not assumed the defense thereof. If the
indemnifying party chooses to defend or prosecute a Third Party Claim, all the
indemnified parties shall cooperate in the defense or prosecution thereof. Such
cooperation shall include the retention and (upon the indemnifying party's
request) the provision to the indemnifying party of records and information that
are reasonably relevant to such Third Party Claim, and making employees
available on a mutually convenient basis to provide additional information and
explanation of any material provided hereunder. Whether or not the indemnifying
party assumes the defense of a Third Party Claim, the indemnified party shall
not admit any liability with respect to, or settle, compromise or discharge,
such Third Party Claim without the indemnifying party's prior written consent
(which consent shall not be unreasonably withheld). If the indemnifying party
assumes the defense of a Third Party Claim, the indemnified party shall agree to
any settlement, compromise or discharge of a Third Party Claim that the
indemnifying party may recommend and that by its terms obligates the
indemnifying party to pay the full amount of the liability in connection with
such Third Party Claim, which releases the indemnified party completely in
connection with such Third Party Claim and that would not otherwise adversely
affect the indemnified party. Notwithstanding the foregoing, the indemnifying
party shall not be entitled to assume the defense of any Third Party Claim (and
shall be liable for the fees and expenses of counsel incurred by the indemnified
party in defending such Third Party Claim) if the Third Party Claim seeks an
order, injunction or other equitable relief or relief for other than money
damages against the indemnified party that the indemnified party reasonably
determines, after conferring with its outside counsel, would reasonably be
expected to have a material adverse effect on the assets, business, financial
condition of results of operations of the indemnified party and cannot be
separated from any related claim for money damages; provided, however, that the
indemnifying party will not be bound by any determination in such Third Party
Claim so defended by the indemnified party, or any compromise or settlement
effected without its consent. If such equitable relief or other relief portion
of the Third Party Claim can be so separated from that for money damages, the
indemnifying party shall be entitled to assume the defense of the portion
relating to money damages.

          (c) Other Claims.  In the event any indemnified party has a claim
against any indemnifying party under Section 8.1 or 8.2 that does not involve a
Third Party Claim being asserted against or sought to be collected from such
indemnified party, the indemnified party shall deliver notice of such claim with
reasonable promptness to the indemnifying party.  The failure by any indemnified
party so to notify the indemnifying party shall not relieve the indemnifying
party from any

                                      -11-
<PAGE>

liability that it may have to such indemnified party under Section 8.1 or 8.2,
except to the extent the indemnifying party shall have been actually prejudiced
as a result of such failure. If the indemnifying party does not notify the
indemnified party within 30 calendar days following its receipt of such notice
that the indemnifying party disputes its liability to the indemnified party
under Section 8.1 or 8.2, such claim specified by the indemnified party in such
notice shall be conclusively deemed a liability of the indemnifying party under
Section 8.1 or 8.2 and the indemnifying party shall pay the amount of such
liability to the indemnified party on demand or, in the case of any notice in
which the amount of the claim (or any portion thereof) is estimated, on such
later date when the amount of such claim (or such portion thereof) becomes
finally determined. If the indemnifying party has timely disputed its liability
with respect to such claim, as provided above, the indemnifying party and the
indemnified party shall proceed in good faith to negotiate a resolution of such
dispute and, if not resolved through negotiations, any party may commence
litigation in an appropriate court of competent jurisdiction.

          8.6  Survival of Representations.  The representations and warranties
contained in this Agreement and in the closing certificates delivered at the
closing pursuant to Sections 7.2(a) and 7.3(a) shall survive the Closing and
shall terminate at the close of business two years following the Closing Date.

          8.7  Limitations.
               -----------

          (a) Except with respect to claims based on actual fraud, from and
after the Closing, the rights of the indemnified parties under this Section 8
shall be the sole and exclusive remedies of the indemnified parties and their
respective affiliates with respect to claims resulting from or relating to any
actual or alleged breach of representation or warranty or failure to perform any
covenant contained in this Agreement or otherwise relating to the transactions
that are the subject of this Agreement. Without limiting the generality of the
foregoing, in no event shall Banyan or the Purchaser, their successors or
permitted assigns, be entitled to claim or seek rescission of the transactions
consummated under this Agreement.

          (b) Notwithstanding anything to the contrary contained in this
Agreement, the aggregate liability of Banyan for the sum of all Losses under
this Section 8 shall not exceed $250,000.

          (c) In no event shall any indemnifying party be responsible and liable
for any Losses or other amounts under this Section 8 that are consequential,
incidental, in the nature of lost profits, diminution in value, damage to
reputation or the like, special or punitive or otherwise not actual Losses.

to the Closing as provided below:

consent;

of the Switchboard Purchase Agreement in accordance with the terms thereof.

          9.2    Effect of Termination.  If this Agreement terminates pursuant
to Section 9.1 of this Agreement, all obligations of the parties hereunder shall

            -------------

          10.1 HSR Act Filings.  Each of the parties shall promptly file (or
cause to be filed) any Notification and Report Forms and related material that
it may be required to file with the Federal Trade Commission and the Antitrust
Division of the United States Department of Justice under the HSR Act, shall use
commercially reasonable efforts to obtain an early termination of the applicable
waiting period, and shall make any further filings or information submissions
pursuant thereto that may be necessary, proper or advisable; provided, however,
that no party shall be required to divest any of their respective businesses or
assets, or to take or agree to take any other action or agree to any limitation
that would reasonably be expected to have a material adverse effect on such
party's business, assets or financial condition.

connection with the transactions contemplated by this Agreement asserted by any
person on the basis of any agreement, statement or representation alleged to
have been made by such indemnifying party.

          10.4 Severability.  The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement.

equitable relief as may be granted by a court of competent jurisdiction.

                                  SCHEDULE 1.2

                           Payment of Purchase Price
                           -------------------------

     The Purchase Price of two hundred fifty thousand dollars ($250,000) shall
be paid, in the discretion of the Purchaser, by one of the following three
methods:

     (i)   the Purchaser shall arrange for the placement of advertising and
           promotion of Banyan in the Placement Possibilities and the Available
           Placement Types set forth below, with an aggregate value of two
           hundred and fifty thousand dollars ($250,000) (with prices of
           advertising determined on the same basis as in the Advertising and
           Promotion Agreement);

     (ii)  the Purchaser shall purchase from Banyan an amount of information
           technology services (of the type described on Annex 1.2-I attached to
           this Schedule 1.2) sufficient for Banyan to realize a Margin (as
           defined in this Schedule 1.2) of two hundred and fifty thousand
           dollars ($250,000); or

     (iii) a combination of the foregoing clauses (i) and (ii) which has an
           aggregate value of two hundred and fifty thousand dollars ($250,000).

     The Purchaser shall make the election described in this Schedule 1.2 by
delivering to Banyan written notice thereof pursuant to Section 10.7 of the
Agreement within 30 days of the date of the Agreement.  The obligation of the
Purchaser to pay the Purchase Price is a binding obligation of the Purchaser.
As used in this Schedule 1.2, the term "Margin" shall mean the difference
between the price(s) agreed upon by Banyan and the Purchaser for any information
technology service(s) to be performed by Banyan pursuant to Section 1.2 of the
Agreement and this Schedule 1.2 and Banyan's cost to perform the applicable
service(s).

     To the extent that the Purchaser elects pursuant to this Schedule 1.2 to
constitute the Purchase Price in whole or in part with the purchase from Banyan
of information technology services, the Margin shall apply to all services
performed by or on behalf of Banyan during the period ending one year after the
date of the Agreement.  For purposes of this Schedule 1.2, "performance" shall
include services which are contracted for by the Purchaser during the period
ending one year after the date of the Agreement but are not performed or
completed by Banyan within that period for reasons which are attributable to the
Purchaser.  Notwithstanding the foregoing, the terms and conditions to govern
any services performed by Banyan for the Purchaser shall be governed by a
separate Services Agreement which shall be substantially in the form attached to
this Schedule 1.2 as Annex 1.2-II.

                         -----------------------------

     Banyan Systems Incorporated, a Massachusetts corporation (the "Company"),
for value received, hereby certifies that CBS Corporation, a Pennsylvania
corporation (the "Registered Holder"), is entitled, subject to the terms set
forth below, to purchase from the Company, at any time or from time to time on
or after the date of issuance and on or before June 30, 2000 at not later than
5:00 p.m. (Boston, Massachusetts time), 250,000 shares of Common Stock, $.01 par
value per share, of the Company, at a per share purchase price of $11.27.  The
shares purchasable upon exercise of this Warrant, and the purchase price per
share, each as adjusted from time to time pursuant to the provisions of this
Warrant, are hereinafter referred to as the "Warrant Shares" and the "Purchase
Price," respectively.
<PAGE>

     1.   Exercise.
          --------

          (a) This Warrant may be exercised by the Registered Holder, in whole
or in part, by surrendering this Warrant, with the purchase form appended hereto
as Exhibit I duly executed by the Registered Holder or by the Registered
Holder's duly authorized attorney, at the principal office of the Company, or at
such other office or agency as the Company may designate, accompanied by payment
(by wire transfer) in full, in lawful money of the United States, of the
Purchase Price payable in respect of the number of Warrant Shares purchased upon
such exercise.

          (b) Each exercise of this Warrant shall be deemed to have been
effected immediately prior to the close of business on the day (the "Exercise
Date") on which this Warrant shall have been surrendered to the Company as
provided in subsection 1(a) above.  At such time, the Registered Holder shall be
deemed to have become the holder or holders of record of the Warrant Shares.

          (c) As soon as practicable after the exercise of this Warrant in full
or in part, and in any event within 15 days thereafter, the Company, at its
expense, will cause to be issued in the name of, and delivered to, the
Registered Holder (upon payment by the Registered Holder of any applicable
transfer taxes):

              (i)   a certificate or certificates for the whole number of duly
authorized, validly issued, fully paid and non-assessable Warrant Shares to
which the Registered Holder shall be entitled upon such exercise plus, in lieu
of any fractional share to which the Registered Holder would otherwise be
entitled, cash in an amount determined pursuant to Section 3 hereof; and

              (ii)  in case such exercise is in part only, a new warrant or
warrants (dated the date hereof) of like tenor, calling in the aggregate on the
face or faces thereof for the number of Warrant Shares equal (without giving
effect to any adjustment therein) to the number of such shares called for on the
face of this Warrant minus the number of such shares purchased by the Registered
Holder upon such exercise.

     2.   Adjustments.
          -----------

          (a) General.  The Purchase Price shall be subject to adjustment from
time to time pursuant to the terms of this Section 2.

          (b) Recapitalizations.  If outstanding shares of the Company's Common
Stock shall be subdivided into a greater number of shares or a dividend in
Common Stock shall be paid in respect of Common Stock, the Purchase Price in
effect immediately prior to such subdivision or at the record date of such
dividend shall simultaneously with the effectiveness of such subdivision or
immediately after the record date of such dividend be proportionately reduced.
If outstanding shares of

                                      -2-
<PAGE>

Common Stock shall be combined into a smaller number of shares, the Purchase
Price in effect immediately prior to such combination shall, simultaneously with
the effectiveness of such combination, be proportionately increased.

          (c) Mergers, etc.  If there shall occur any capital reorganization or
reclassification of the Company's Common Stock (other than a change in par value
or a subdivision or combination as provided for in subsection 2(b) above), or
any consolidation or merger of the Company with or into another corporation, or
a transfer of all or substantially all of the assets of the Company, then, as
part of any such reorganization, reclassification, consolidation, merger or
sale, as the case may be, lawful provision shall be made so that the Registered
Holder shall have the right thereafter to receive upon the exercise hereof the
kind and amount of shares of stock or other securities or property which such
Registered Holder would have been entitled to receive if, immediately prior to
any such reorganization, reclassification, consolidation, merger or sale, as the
case may be, such Registered Holder had held the number of shares of Common
Stock which were then purchasable upon the exercise of this Warrant.  In any
such case, appropriate adjustment (as reasonably determined in good faith by the
Board of Directors of the Company) shall be made in the application of the
provisions set forth herein with respect to the rights and interests thereafter
of the Registered Holder, such that the provisions set forth in this Section 2
(including provisions with respect to adjustment of the Purchase Price) shall
thereafter be applicable, as nearly as is reasonably practicable, in relation to
any shares of stock or other securities or property thereafter deliverable upon
the exercise of this Warrant.

          (d) Adjustment in Number of Warrant Shares.  When any adjustment is
required to be made in the Purchase Price pursuant to Section 2(c), the number
of Warrant Shares purchasable upon the exercise of this Warrant shall be changed
to the number determined by dividing (i) an amount equal to the number of shares
issuable upon the exercise of this Warrant immediately prior to such adjustment,
multiplied by the Purchase Price in effect immediately prior to such adjustment,
by (ii) the Purchase Price in effect immediately after such adjustment.

          (e) Certificate of Adjustment.  When any adjustment is required to be
made pursuant to this Section 2, the Company shall promptly mail to the
Registered Holder a certificate setting forth the Purchase Price after such
adjustment and setting forth a brief statement of the facts requiring such
adjustment.  Such certificate shall also set forth the kind and amount of stock
or other securities or property into which this Warrant shall be exercisable
following such adjustment.

     3.   Fractional Shares.  The Company shall not be required upon the
exercise of this Warrant to issue any fractional shares, but shall make an
adjustment therefor in cash on the basis of the fair market value per share of
Common Stock, based on the last sale price on the Exercise Date.

                                      -3-

     4.   Requirements for Transfer.  Neither this Warrant nor any interest
          -------------------------
herein is transferrable in any respect.

     5.   No Impairment.  The Company will not, by amendment of its charter or
through reorganization, consolidation, merger, dissolution, sale of assets or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant, but will at all times in good faith assist
in the carrying out of all such terms and in the taking of all such action as
may be necessary or appropriate, including such action as may be necessary or
appropriate in order that the Company may validly and legally issue or sell
fully paid and non-assessable Warrant Shares upon exercise of this Warrant, in
order to protect the rights of the holder of this Warrant against impairment.

     6.   Notices of Record Date, etc.  In case:
          ---------------------------

          (a) the Company shall take a record of the holders of its Common Stock
(or other stock or securities at the time deliverable upon the exercise of this
Warrant) for the purpose of entitling or enabling them to receive any dividend
or other distribution, or to receive any right to subscribe for or purchase any
shares of stock of any class or any other securities, or to receive any other
right; or

          (b) of any capital reorganization of the Company, any reclassification
of the Common Stock of the Company, any consolidation or merger of the Company
with or into another corporation (other than a consolidation or merger in which
the Company is the surviving entity), or any transfer of all or substantially
all of the assets of the Company; or

          (c) of the voluntary or involuntary dissolution, liquidation or
winding-up of the Company,

then, and in each such case, the Company will mail or cause to be mailed to the
Registered Holder a notice specifying, as the case may be, (i) the record date
for such dividend, distribution or right, and the amount and character of such
dividend, distribution or right, or (ii) the effective date on which such
reorganization, reclassification, consolidation, merger, transfer, dissolution,
liquidation or winding-up is to take place, and the time, if any is to be fixed,
as of which the holders of record of Common Stock (or such other stock or
securities at the time deliverable upon the exercise of this Warrant) shall be
entitled to exchange their shares of Common Stock (or such other stock or
securities) for securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger, transfer, dissolution,
liquidation or winding-up.  Such notice shall be mailed at least ten (10) days
prior to the record date or effective date for the event specified in such
notice.

                                      -4-
<PAGE>

     7.   Reservation of Stock.  The Company will at all times reserve and keep
available, solely for issuance and delivery upon the exercise of this Warrant,
such number of Warrant Shares and other stock, securities and property, as from
time to time shall be issuable upon the exercise of this Warrant.  All Warrant
Shares shall be duly authorized and, when issued upon such exercise, shall be
validly issued, fully paid and non-assessable and free and clear of all
preemptive rights, and free from all taxes, liens and other charges with respect
to the issue thereof by the Company.  The Company will take all actions as may
be necessary to assure that the Warrant Shares issued upon a valid exercise
hereof may be issued by the Company without violation of any law or regulation,
or of any requirement of any domestic securities exchange upon which any capital
stock of the Company may be listed.

     8.   Replacement of Warrants.  Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and (in the case of loss, theft or destruction) upon delivery of an
indemnity agreement (with surety if reasonably required) in an amount reasonably
satisfactory to the Company, or (in the case of mutilation) upon surrender and
cancellation of this Warrant, the Company will issue, in lieu thereof, a new
Warrant of like tenor.

     9.   Mailing of Notices, etc.  All notices and other communications from
the Company to the Registered Holder shall be mailed by first-class certified or
registered mail, postage prepaid, to the address last furnished to the Company
in writing by the Registered Holder.  All notices and other communications from
the Registered Holder or in connection herewith to the Company shall be mailed
by first-class certified or registered mail, postage prepaid, to the Company at
120 Flanders Road, Westboro, MA 01581, Attn:  Chief Financial Officer, with a
copy to Hale and Dorr LLP, 60 State Street, Boston, MA  02109, Attn:  Mark G.
Borden, Esq.  If the Company should at any time change the location of its
principal office to a place other than as set forth below, it shall give prompt
written notice to the Registered Holder and thereafter all references in this
Warrant to the location of its principal office at the particular time shall be
as so specified in such notice.

     10.  No Rights as Stockholder.  Until the exercise of this Warrant, the
Registered Holder shall not have or exercise any rights by virtue hereof as a
stockholder of the Company.

     11.  Change or Waiver.  Any term of this Warrant may be changed or waived
only by an instrument in writing signed by the party against which enforcement
of the change or waiver is sought.

     12.  Remedies. In case any one or more of the covenants and agreements
contained in this Warrant shall have been breached, the Registered Holder hereof
(in the case of a breach by the

                                      -5-
<PAGE>

Company), or the Company (in the case of a breach by the Registered Holder), may
proceed to protect and enforce its rights either by suit in equity and/or by
action at law, including, but not limited to, an action for damages as a result
of any such breach and/or an action for specific performance of any such
covenant or agreement contained in this Warrant.

     13.  Headings.  The headings in this Warrant are for purposes of reference
only and shall not limit or otherwise affect the meaning of any provision of
this Warrant.

     14.  Governing Law.  This Warrant will be governed by and construed in
accordance with the laws of the Commonwealth of Massachusetts (without reference
to the conflicts of law provisions thereof).

     15.  Waiver of Jury Trial.  THE COMPANY AND THE REGISTERED HOLDER WAIVE THE
RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED HEREON.
