              NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS
                                  (unaudited)

A.   Basis of Presentation

     The accompanying unaudited consolidated financial statements have been
prepared by Engage Technologies, Inc. ("Engage" or the "Company") in accordance
with generally accepted accounting principles for interim financial information
and with the instructions to Form 10-Q and Article 10 of Regulation S-X.
Accordingly, these unaudited consolidated financial statements do not include
all of the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, the
accompanying 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 audited financial statements and related notes for the year
ended July 31, 1999 which are contained in the Company's Annual Report on Form
10-K filed with the Securities and Exchange Commission ("the SEC") on October
29, 1999. The results for the three-month period ended October 31, 1999 are not
necessarily indicative of the results to be expected for the full fiscal year.

B.   Cash and Short-Term Investments

     Engage's cash is invested in debt instruments of financial institutions and
corporations, and in a money market mutual fund. Engage has established
guidelines relative to credit ratings, diversification, and maturities that help
maintain safety and liquidity. Cash equivalents include highly liquid
investments with maturity periods of three months or less when purchased. Short-
term investments include those investments with maturities in excess of three
months but less than one year. Equity securities represent shares of Informix
Corporation. Short-term investments and marketable equity securities are
classified as available for sale and reported at fair value with unrealized
gains and losses included in stockholders' equity. Engage has not had any
significant losses related to its investments.

C.   Earnings Per Share

     The Company calculates earnings per share in accordance with Statement of
Financial Accounting Standards (SFAS) No. 128, "Earnings per Share". Basic
earnings per share is computed based on the weighted average number of common
shares outstanding during the period. The dilutive effect of common stock
equivalents are included in the calculation of diluted earnings per share only
when the effect of their inclusion would be dilutive.

     Pro forma basic loss per share is based upon the weighted average number of
common shares outstanding during the period. Pro forma diluted loss per share is
based upon the weighted average number of common shares outstanding during the
period plus additional weighted average common equivalent shares outstanding
during the period, computed using the "if-converted method". Common equivalent
shares have been excluded from the computation of diluted loss per share in each
period, as their effect would have been anti-dilutive in each period presented.

     Conversion of all preferred stock and debt to CMGI occurred upon the
completion of the Company's initial public offering in July 1999. The pro forma
basic and diluted net loss per share information included in the accompanying
statements of operations for the three months ended October 31, 1998 reflects
the impact on pro forma basic and diluted net loss per share of such conversion
as of the beginning of each period or date of issuance, if later, using the if-
converted method. Historical basic and diluted net loss per share has not been
presented for the three-month period ended October 31, 1998 because it is
irrelevant due to the change in the Company's capital structure and resultant
basic and diluted loss per share that resulted upon conversion of the
convertible preferred stock and debt to CMGI. Pro forma basic and diluted net
loss per share has been presented for comparative purposes.

     The reconciliation of the numerators and denominators of the basic and
diluted loss per share computation for the Company's reported net loss is as
follows:

</TABLE>

     At July 31, 1999, the Company had available-for sale securities recorded at
amortized cost totaling $1,067,000.

F.   Non-Cash Transactions

     During the three months ended October 31, 1999, as the result of the
termination of employment of certain employees prior to the vesting of their
stock options, unvested stock options for which deferred compensation costs had
been recorded in a prior period were cancelled. As a result of these
cancellations, the Company has recorded a reduction of $1,673,000 in both
deferred compensation and additional paid-in capital.

G.   Subsequent Event

     In September 1999, the Company signed an agreement pursuant to which it
will acquire AdKnowledge, Inc. ("AdKnowledge"), a provider of products and
services which allow online marketers and ad agencies to plan, target, serve,
track and analyze advertising campaigns. Under the terms of the merger and
contribution agreement, CMGI will initially acquire control of AdKnowledge
through the issuance of approximately $170 million of CMGI common stock in a
merger of a subsidiary of CMGI into AdKnowledge. The value of the CMGI common
stock being delivered is based on $93.28, the average of the last reported sales
prices of the CMGI common stock over the 45 consecutive trading days ending two
trading days prior to the effective time of this merger. This merger was
completed on November 30, 1999, with CMGI owning approximately 88% of the common
stock of AdKnowledge on such date. This merger will be followed by a
contribution of AdKnowledge shares held by CMGI and AdKnowledge shareholders to
the Company in exchange for approximately $193 million of the Company's common
stock, $0.01 par value per share (the "Common Stock"). The value of the Common
Stock being delivered is $34.59, the average of the last reported sales price of
the Company's Common Stock over the 45 consecutive trading days ending two
trading days prior to the effective time of this merger. Any remaining holders
of AdKnowledge common stock will receive the Company's Common Stock in a short-
form merger with a subsidiary of the Company. Included in the purchase price are
$19.3 million in Common Stock that will be held in escrow for the purpose of
securing the indemnification obligations of those AdKnowledge shareholders who
receive merger shares and certain performance and employee retention milestones.

Additional information related to the proposed interested party transaction is
available in the Company's definitive proxy statement filed with the Securities
and Exchange Commission on November 19, 1999.

H.   New Accounting Pronouncements

     In November 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin ("SAB") No. 100, "Restructuring and Impairment
Charges." In December 1999 the SEC issued SAB No. 101, "Revenue Recognition in
Financial Statements." SAB No. 100 expresses the views of the SEC staff
regarding the accounting for and disclosure of certain expenses not commonly
reported in connection with exit activities and business combinations. This
includes the accrual of exit and employee termination costs and the recognition
of impairment charges. SAB No. 101 expresses the views of the SEC staff in
applying generally accepted accounting principles to certain revenue recognition
issues. Although the Company is still in the process of analyzing the impact of
SAB No. 100 and SAB No. 101, if any, on its consolidated financial statements
and related disclosures, the Company expects that there will be no material
impact on its financial position or its results of operations.

Results of Operations

  Engage is a leading provider of profile-based Internet marketing solutions.
Engage is an approximately 79% owned subsidiary of CMGI, Inc ("CMGI").  The
Company offers a range of products and services that enable Web publishers,
advertisers and merchants to target the delivery of advertisements, content and
e-commerce offerings to their audiences and to measure their effectiveness.
Engage has generated most of its revenue to date through sales of its local
profiling and advertising management software and outsourced services, as well
as its services for measuring and analyzing Web site traffic. In July 1999,
Engage commercially introduced its Engage Knowledge data service to customers.
Engage Knowledge provides real-time access to Engage's database of more than 42
million anonymous profiles of Web users for more effective targeting of online
advertising, promotions and content.  In October 1999, Engage introduced Engage
AudienceNet, the first Web-wide profile driven advertising and marketing network
that uses Engage's anonymous, behavior based profiles to deliver substantial
benefits to media buyers, Web sites and ad networks.

  In April 1999, Engage acquired Internet Profiles Corporation ("I/PRO"), which
provides Web site traffic measurement and audit services.  The acquisition has
been accounted for using the purchase method, and accordingly, the purchase
price has been allocated to the assets purchased and liabilities assumed based
upon their fair values at the date of acquisition.

  In September 1999, the Company signed an agreement pursuant to which it will
acquire AdKnowledge, Inc. ("AdKnowledge"), a provider of products and services
which allow online marketers and ad agencies to plan, target, serve, track and
analyze advertising campaigns.  Under the terms of the merger and contribution
agreement, CMGI will initially acquire control of AdKnowledge through the
issuance of approximately $170 million of CMGI common stock in a merger of a
subsidiary of CMGI into AdKnowledge.  The value of the CMGI common stock being
delivered is based on $93.28, the average of the last reported sales prices of
the CMGI common stock over the 45 consecutive trading days ending two trading
days prior to the effective time of this merger. This merger was completed on
November 30, 1999, with CMGI owning approximately 88% of the common stock of
AdKnowledge on such date.  This merger will be followed by a contribution of
AdKnowledge shares held by CMGI and AdKnowledge shareholders to the Company in
exchange for approximately $193 million of the Company's common stock, $0.01 par
value per share (the "Common Stock").  The value of the Common Stock being
delivered is $34.59, the average of the last reported sales price of the
Company's Common Stock over the 45 consecutive trading days ending two trading
days prior to the effective time of this merger.  Any remaining holders of
AdKnowledge common stock will receive the Company's Common Stock in a short-form
merger with a subsidiary of the Company.  Included in the purchase price are
$19.3 million in Common Stock that will be held in escrow for the purpose of
securing the indemnification obligations of those AdKnowledge shareholders who
receive merger shares and certain performance and employee retention milestones.

Revenue

  Total revenue increased from $1.6 million for the three months ended October
31, 1998 to $8.3 million for the three months ended October 31, 1999. Revenue
from the Company's product offerings accounted for approximately 84% of total
revenue for the three months ended October 31, 1998, compared to 82% of total
revenue for the three months ended October 31, 1999.  The increase in total
revenue was primarily the result of an increase in revenue derived from the
increased sales of the Company's AdManager, DecisionSupportServer and
ProfileServer products, and to a lesser extent,  the inclusion of I/PRO's
revenue in product revenue for the three months ended October 31, 1999.

  Product revenue increased from $1.3 million for the three months ended October
31, 1998 to $6.8 million for the three months ended October 31, 1999.
Approximately 50% of this increase resulted from increased sales of products
available in each period due to increased market awareness and acceptance of the
Company's products. The balance of the increase was the result of the I/PRO
acquisition and the introduction of new products that were not available for the
three months ended October 31, 1998.

  Service and support revenue increased from $255,000 for the three months ended
October 31, 1998 to $1.5 million for the three months ended October 31, 1999.
The 483% increase quarter-over-quarter was the result of increased software
support and maintenance revenue resulting from increased product revenue and two
large consulting arrangements during the three months ended October 31, 1999.

Cost of Revenue

  Cost of product revenue includes royalties paid to various parties for the
incorporation of their technology into Engage's products, costs associated with
the I/PRO, Engage Knowledge and AudienceNet product offerings, as well as fees
paid for outsourced data center operations and the amortization of developed
technology acquired in the Accipiter and I/PRO acquisitions. Cost of support and
services revenue is primarily comprised of payroll and benefits, and allocated
overhead costs associated with Engage's customer support and consulting groups.

  Cost of product revenue increased from $582,000 for the three months ended
October 31, 1998 to $3.2 million for the three months ended October 31, 1999. Of
the total dollar increase, $1.6 million was due to the I/PRO acquisition and the
resultant three months of incremental operational costs associated with I/PRO's
product offerings.  In addition, a significant portion of the increase was
associated with Engage's AdBureau, Engage Knowledge and AudienceNet products.
Finally, a portion of the increase was the result of increased amortization
costs resulting from the amortization of developed technology acquired in the
I/PRO acquisition. Cost of product revenue was 44% of product revenue for the
three months ended October 31, 1998, compared to 47% of product revenue for the
three months ended October 31, 1999. The increase in cost of product revenue as
a percentage of product revenue was the result of the inclusion of revenue from
I/PRO products in revenue for the three months ended October 31, 1999.

  Cost of service and support revenue increased from $625,000 for the three
months ended October 31, 1998 to $1.2 million for the three months ended October
31, 1999. Costs for the three months ended October 31, 1998 exceeded the related
revenue due to Engage's continued investment in service and support staff in
advance of anticipated product sales. Engage's service and support staff
increased 227% from October 31, 1998 to October 31, 1999. Engage expects to
continue to expand its service and support staff and anticipates that costs may
exceed revenue for several more quarters. Cost of service and support revenue
was 245% of service and support revenue at October 31, 1998, compared to 78% of
service and support revenue at October 31, 1999. As a percentage of service and
support revenue, the improvement in costs reflects the continued growth of the
Company's service and support business and the spreading of certain fixed costs
over a growing revenue base. Additionally, the Company had two large consulting
arrangements during the three months ended October 31, 1999.

Operating Expenses

  Research and Development. Research and development expenses consist primarily
of payroll and related costs, consulting and contractor fees, facility-related
costs, such as rent and computer and network services, and depreciation expense.
Research and development expenses increased from $2.0 million for the three
months ended

                                       11
<PAGE>

October 31, 1998 to $3.3 million for the three months ended October
31, 1999, a 68% increase. This increase was due to the I/PRO acquisition and the
inclusion of I/PRO's operations for the three months ended October 31, 1999, and
to a lesser extent, the expansion of the Company's research and development
activities.  Overall, including the acquisition of I/PRO, Engage's research and
development staff increased 121% from October 31, 1998 to October 31, 1999.
These increases were offset somewhat by a decrease in spending on the
translation of Engage's products into certain foreign languages, projects which
were substantially completed during fiscal 1999.  Research and development
expenses were 124% of total revenue for the three months ended October 31, 1998,
compared to 40% of total revenue for the three months ended October 31, 1999.
This decrease is the direct result of the increase in quarter over quarter
revenue.

  Selling and Marketing. Selling and marketing expenses consist primarily of
payroll and related costs, consulting and professional fees and advertising
expenses. Selling and marketing expenses increased from $1.9 million for the
three months ended October 31, 1998 to $8.0 million for the three months ended
October 31, 1999, a 332% increase. The increase in costs was primarily due to
the continuing expansion of Engage's sales force, as well as approximately $1.6
million resulting from the I/PRO acquisition and the inclusion of I/PRO's
operations for the three months ended October 31, 1999.  Overall, including the
acquisition of I/PRO, Engage's sales and marketing staff increased 359% from
October 31, 1998 to October 31, 1999. In addition, a portion of the increase was
related to increases in product advertising costs resulting from the release of
new products. Sales and marketing expenses were 117% of total revenues for the
three months ended October 31, 1998, compared to 97% for the three months ended
October 31, 1999.  The decrease is the result of the increase in quarter over
quarter revenue.

  General and Administrative. General and administrative costs consist
principally of payroll and related costs, consulting and professional fees,
facility and related costs and depreciation expense. General and administrative
expenses increased from $687,000 for the three months ended October 31, 1998 to
$1.8 million for the three months ended October 31, 1999, a 164% increase. The
increase was primarily due to an increase in payroll and related costs
associated with the support of growing operations and from the inclusion of
I/PRO's operations for the three months ended October 31, 1999. General and
administrative costs were 43% of total revenue for the three months ended
October 31, 1998, compared to 22% for the three months ended October 31, 1999.
The decrease is the result of the increase in quarter over quarter revenue.

  Amortization of Goodwill and Other Intangibles. Amortization of intangible
assets increased from $1.0 million for the three months ended October 31, 1998
to $2.3 million for the three months ended October 31, 1999. The increase was
due to the acquisition of I/PRO in April 1999.

  Stock Compensation. Stock compensation costs decreased from $196,000 for the
three months ended October 31, 1998 to $102,000 for the three months ended
October 31, 1999. Beginning in April 1998, Engage commenced the recognition of
compensation expense relating to approximately 173,080 shares of CMGI common
stock held in escrow to be issued to the employee stockholders of Accipiter who
satisfy a two-year employment continuation provision. Additionally, beginning in
February 1999, Engage began to recognize stock compensation costs as a result of
stock options granted during fiscal 1999 with exercise prices below the
estimated fair market value of the common stock at the date of grant. During the
three months ended October 31, 1999, as the result of the termination of
employment of certain employees prior to the vesting of their stock options, the
Company reversed $122,000 of stock compensation expense that had been recorded
in prior quarters and ceased monthly stock compensation expense recognition
related to the terminated employees. As such, for the three months ended October
31, 1999 the increase in stock compensation costs resulting from the stock
options issued in February 1999 was more than offset by the reversal of
compensation costs recorded in prior periods.

Equity in Loss of Joint Venture

  Equity in loss of Engage's 46% interest in a Japanese joint venture was
$10,000 for the three months ended October 31, 1998, compared to $326,000 for
the three months ended October 31, 1999. The increase in Engage's share of
losses in the joint venture represents the joint venture's continued investment
in expanding its sales and marketing presence within its market.

                                      12
<PAGE>

Interest (Expense) Income, Net

  Interest expense, net was $160,000 for the three months ended October 31,
1998, compared to interest income, net of $1.3 million for the three months
ended October 31, 1999. During fiscal 1998, Engage entered into an arrangement
with CMGI which required Engage to accrue interest on intercompany debt at a
rate of 7% per annum. During the three months ended October 31, 1998, interest
expense was recorded on this debt, all of which was converted into equity in
connection with Engage's initial public offering in July 1999.  During the three
months ended October 31, 1999, interest income was earned from investing the
proceeds of the Company's initial public offering.

Liquidity and Capital Resources

  The Company's cash and cash equivalents decreased from $112.0 million at July
31, 1999 to $46.1 million at October 31, 1999, primarily the result of investing
$54.0 million in available-for-sale securities and investing $2.0 million in a
strategic partner of the Company. The company recorded the $2.0 million
investment at cost, and has classified the investment within Other Assets  In
addition, a portion of the decrease is the result of $10.3 million used to fund
operating activities and $706,000 used to acquire property and equipment.
Historically, the Company has funded its operations and capital expenditures
through funds received from CMGI and recently from its initial public offering
proceeds.

  The Company has experienced a substantial increase in its expenditures since
inception consistent with its growth in operations and staffing.  The Company
anticipates that expenditures will continue to increase for the foreseeable
future as the Company accelerates the growth of its business. Additionally, the
Company will continue to evaluate investment opportunities in businesses that
management believes will complement its technologies and marketing strategies.

  The Company currently anticipates that its available cash resources will be
sufficient to meet its anticipated needs for working capital and capital
expenditures for at least the next 12 months. However, the Company may need to
raise additional funds in order to fund more rapid expansion, to develop new or
enhance existing services or products, to respond to competitive pressures or to
acquire complementary products, businesses or technologies. On a long-term
basis, the Company may require additional external financing through credit
facilities, sales of additional equity or other debt instruments. If additional
funds are raised through the issuance of equity or convertible debt securities,
the percentage ownership of the Company's stockholders will be reduced and its
stockholders may experience additional dilution. If adequate funds are not
available or are not available on acceptable terms, the Company's ability to
fund its expansion, take advantage of unanticipated opportunities, develop or
enhance services or products or otherwise respond to competitive pressures may
be significantly limited.

Foreign Operations

  The results of the Company's international operations are subject to currency
fluctuations.  As of October 31, 1999, the Company had subsidiaries in the
United Kingdom and Germany, and had a joint venture in Japan. To date, the
Company's financial condition and results of operations have not been materially
affected by exchange rate fluctuations.  However, as these operations continue
to grow, and operations are commenced in additional countries, there can be no
guarantee that the Company's financial condition and results of operations will
not be adversely affected by exchange rate fluctuations.

Year 2000 Compliance

  Many currently installed computer systems and software products are coded to
accept only two digit entries in the date code field. These date code fields
will need to accept four digit entries to distinguish 21st century dates from
20th century dates. As a result, many companies' software and computer systems
may need to be upgraded or replaced in order to comply with these "Year 2000"
requirements or risk system failure or miscalculations causing disruptions of
normal business activities. The Company is in the process of correcting the Year
2000 compliance of its proprietary products and services and third party
equipment and software that it uses, as well as its non-information technology
systems, such as building security, voice mail and other systems.

                                       13
<PAGE>

State of Readiness

   The Company has made an assessment of the Year 2000 readiness of its
operating, financial and administrative systems, including the hardware and
software that support the Company's systems. The Company's Year 2000 compliance
efforts and status of such efforts as of December 1999 consist of the following:

   .   Identification of all software products, information technology systems
       and non-information technology systems that may be affected by Year 2000
       issues. This phase has been substantially completed.

   .   Assessment of repair or replacement requirements. This phase has been
       substantially completed.

   .   Repair or replacement. This phase has been substantially completed.

   .   Testing of software products is substantially completed.

   .   Implementation of repaired software products is substantially completed.

   .   Creation of contingency plans in the event of Year 2000 failures. This
       phase has been substantially completed.

   For its currently marketed software products, the Company has substantially
completed its Year 2000 compliance testing efforts and believes that its
products are Year 2000 compliant in all material respects. The Company also has
conducted less extensive testing of older versions of its products. While the
Company is not aware of any material respect in which its older products are not
Year 2000 compliant, it has offered customers using older products the option to
upgrade to current versions at no additional charge. The Company also has tested
its internal and third party provided systems that are used to deliver customer
services. The Company has received assurances from NaviSite, a major third-party
vendor and affiliate, that NaviSite will be responsible for ensuring that its
system is Year 2000 ready.

   For all other systems, the Company's Year 2000 task force has inventoried and
tested all software and related systems that it believes may be affected by Year
2000 issues. Since third parties developed and currently support many of the
systems that the Company uses, a significant part of this effort has been to
ensure that these third-party systems are Year 2000 compliant. The internal
evaluation has resulted in the identification of a small number of desktop
computers whose operating systems were not Year 2000 compliant. These computers
were replaced by the Company in the third quarter of fiscal 1999.

Costs

   At October 31, 1999, the Company had spent approximately $960,000 on Year
2000 compliance issues and expects to incur an additional $240,000 in connection
with identifying, evaluating and addressing Year 2000 compliance issues. Most of
the Company's expenses have related to the operating costs associated with time
spent by employees and consultants in the evaluation process and Year 2000
compliance matters and costs to replace non-compliant equipment. Future costs
are expected to consist principally of operating costs associated with
consultants. Such expenses, if higher than anticipated, could have a material
adverse effect on the Company's business, financial condition and results of
operations.

Risks

   The Company is not currently aware of any Year 2000 compliance problems
relating to its products or systems that would have a material adverse effect on
its business, financial condition and results of operations, without taking into
account the Company's efforts to avoid or fix such problems. There can be no
assurance that the Company will not discover Year 2000 compliance problems in
its products or systems that will require substantial revision. In addition,
there can be no assurance that third-party software, hardware or services
incorporated into the Company's material systems will not need to be revised or
replaced, all of which could be time-consuming and expensive. The failure of the
Company to fix or replace its internally developed proprietary software or
third-party software, hardware or services on a timely basis could result in
lost revenue, increased operating costs, the loss of

                                       14
<PAGE>

customers and other business interruptions, any of which could have a material
adverse effect on the Company's business, financial condition and results of
operations. Moreover, the failure to adequately address Year 2000 compliance
issues in its internally developed proprietary software could result in claims
of mismanagement, misrepresentation or breach of contract and related
litigation, which could be costly and time-consuming to defend.

  The Company is heavily dependent on NaviSite to provide outsourced data
services. A significant Year 2000 related disruption of the outsourced data
services that NaviSite provides to the Company could cause customers to consider
canceling services with the Company or cause an unmanageable burden on the
Company's technical support, which in turn could materially and adversely affect
the Company's business, financial condition and results of operations.

  In addition, there can be no assurance that governmental agencies, utility
companies, Internet access companies, third-party service providers and others
outside of the Company's control will be Year 2000 compliant. The failure by
such entities to be Year 2000 compliant could result in a systemic failure
beyond the control of the Company, such as a prolonged Internet,
telecommunications or electrical failure, which could also prevent the Company
from delivering its services to its customers, decrease the use of the Internet
or prevent users from accessing its Web sites which could have a material
adverse effect on the Company's business, financial condition and results of
operations.

Contingency Plan

  As discussed above, the Company has developed Year 2000 contingency plans. The
results of the Company's Year 2000 simulation testing and the responses received
from third-party vendors and service providers were taken into account in
writing contingency plans. Contingency plans will be reviewed and updated as
needed to reflect any changes in staffing, business process, or vendor
dependencies.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

  The carrying values of financial instruments including cash and cash
equivalents, available-for-sale securities, accounts receivable, accounts
payable and notes payable, approximate fair value because of the short maturity
of these instruments.

  The Company has historically had very low exposure to changes in foreign
currency exchange rates, and as such, has not used derivative financial
instruments to manage foreign currency fluctuation risk. As the Company expands
globally, the risk of foreign currency exchange rate fluctuation may increase.
Therefore, in the future, the Company may consider utilizing derivative
instruments to mitigate such risks.

                         PART II.     OTHER INFORMATION

Item 2.  Changes in Securities and Use of Proceeds

  In September 1999, five former employees exercised options to purchase an
aggregate of 31,743 shares of the Company's Common Stock for an aggregate
purchase price of $19,971. In October 1999, two former employees exercised
options to purchase an aggregate of 1,864 shares of the Company's Common Stock
for an aggregate purchase price of $736. No underwriters were involved in the
foregoing offers and sales of securities. Such offers and sales were made in
reliance upon an exemption from the registration provisions of the Securities
Act of 1933, as amended (the "Securities Act"), set forth in Rule 701 under the
Securities Act.

  In connection with the Company's initial public offering, on July 19, 1999,
the Securities and Exchange Commission declared the Company's Registration
Statement on Form S-1 (File No. 333-78015) effective.  Goldman, Sachs & Co.,

                 AGREEMENT AND PLAN OF MERGER AND CONTRIBUTION

     Agreement and Plan of Merger and Contribution (the "Agreement") entered
into as of September 23, 1999 by and among CMGI, Inc., a Delaware corporation
("CMGI"), Engage Technologies, Inc., a Delaware corporation and a majority-owned
subsidiary of CMGI ("Engage"), AK Acquisition Corp., a California corporation
and a wholly-owned subsidiary of CMGI (the "Transitory Subsidiary"), AdKnowledge
Inc., a California corporation (the "Company"), and Steve Findley, John Mracek
and Kevin Wandryk (collectively, the "Shareholder Representative") (CMGI,
Engage, Transitory Subsidiary, the Company and the Shareholder Representative
are referred to collectively herein as the "Parties.")

     This Agreement contemplates:

          First, a merger of Transitory Subsidiary with and into the Company,
     with the Company being the surviving corporation. In such merger, (i) all
     the shareholders of the Company holding shares of Company Preferred Stock
     (as defined below) will receive shares of (A) the common stock, $.01 par
     value par share, of CMGI ("CMGI Common Stock") and (B) a new class of
     common stock of the surviving corporation, $.01 par value per share
     ("Surviving Corporation Common Stock"), in exchange therefor, (ii) all the
     shareholders of the Company holding shares of the Company's common stock
     ("Company Common Stock") will receive shares of Surviving Corporation
     Common Stock, in exchange therefor (the Surviving Corporation Common Stock
     issued under (i) and (ii) shall aggregate approximately 12% of the issued
     and outstanding Surviving Corporation Common Stock), and (iii) CMGI will
     receive Surviving Corporation Common Stock in exchange for the common
     stock, $.01 par value per share, of Transitory Subsidiary ("Transitory
     Subsidiary Stock"), in an aggregate amount equal to approximately 88% of
     the issued and outstanding Surviving Corporation Common Stock. The merger
     is intended to qualify as a tax-free reorganization under Section 368(a) of
     the Internal Revenue Code of 1986, as amended (the "Code").

          Second, all the shareholders of the surviving corporation will
     contribute their Surviving Corporation Common Stock to Engage in exchange
     for shares of the common stock, $.01 par value per share, of Engage
     ("Engage Common Stock"), in a transaction intended to qualify as a
     transaction under Section 351 of the Code.

          Third, Engage will consummate a California short-form merger between
     the Surviving Corporation and a wholly-owned subsidiary of Engage ("Engage
     Sub"), pursuant to which Engage Sub will merge with and into the Surviving
     Corporation, with the Surviving Corporation being the surviving corporation
     in such merger and the remaining holders of Surviving Corporation Common
     Stock will receive Engage Common Stock in exchange therefor.

     Now, therefore, in consideration of the representations, warranties and
covenants herein contained, the Parties agree as follows.

          -----------------
the Merger Effective Time, take any action, including executing and delivering
any document, in the name and on behalf of either the Company or Transitory
Subsidiary, in order to consummate the transactions contemplated by this
Agreement.

     1.5  Conversion of Shares.  At the Merger Effective Time, by virtue of the
          --------------------
Merger and without any action on the part of any Party or the holder of any of
the following securities:

          (a)  Conversion of Company Preferred Stock.
               -------------------------------------

               (i)   Each share of the Company's Series A Convertible Preferred
Stock, Series B Convertible Preferred Stock, Series C-1 Convertible Preferred
Stock, Series C-2 Convertible Preferred Stock, Series C-3 Convertible Preferred
Stock, Series D Convertible Preferred Stock, Series E Convertible Preferred
Stock and Series F Convertible Preferred Stock (collectively, the "Company
Preferred Stock") issued and outstanding immediately prior to the Merger
Effective Time (other than Merger Dissenting Shares) shall be converted into and
represent the right to receive (subject to the provisions of Section 1.10) (A)
the number of shares of CMGI Common Stock determined by multiplying the CMGI
Conversion Ratio by the number of shares of Company Common Stock into which each
share of Company Preferred Stock is convertible immediately prior to the Merger
Effective Time, and (B) the number of shares of Surviving Corporation Common
Stock determined by multiplying the Preferred Ratio by the number of shares of
Company Common Stock into which each share of Company Preferred Stock is
convertible immediately prior to the Merger Effective Time.

               (ii)  The "Preferred Ratio" shall be equal to the remainder of
subtracting (A) the quotient of (x) 88.083% of the number of shares of Company
Common Stock outstanding immediately prior to the Merger Effective Time
(assuming the conversion into Company Common Stock of all outstanding Company
Preferred Stock and the exercise of all Company Options and Warrants) (the
"Total Outstanding Company Common Stock") divided by (y) the number of shares of
Company Common Stock which would be issuable upon conversion of all Company
Preferred Stock outstanding immediately prior to the Merger Effective Time into
Company Common Stock, from (B) one (1).

               (iii) The "CMGI Conversion Ratio" shall be the result obtained by
dividing (A) the quotient of (i) $170,000,000 divided by (ii) the CMGI Lock-In
Value (as defined below) by (B) the number of shares of Company Common Stock
which would be issuable upon conversion of all Company Preferred Stock
outstanding immediately prior to the Merger Effective Time into Company Common
Stock.

               (iv)  The "CMGI Lock-In Value" shall be determined as follows:

                                       3
<PAGE>

                    (A) In the event that the average of the last reported sale
prices per share of CMGI Common Stock on the Nasdaq National Market over the
forty-five (45) consecutive trading days ending on the trading day that is two
trading days prior to the Merger Effective Time (the "CMGI Final Value") is
equal to or less than ninety percent (90%) of the average of the last reported
sale prices per share of CMGI Common Stock on the Nasdaq National Market over
the forty-five (45) consecutive trading days ending on the trading day that is
two trading days prior to the date of this Agreement (the "CMGI Initial Value"),
then the CMGI Lock-In Value shall be ninety percent (90%) of the CMGI Initial
Value.

                    (B) In the event that the CMGI Final Value is equal to or
greater than one hundred ten percent (110%) of the CMGI Initial Value, the CMGI
Lock-In Value shall be one hundred ten percent (110%) of the CMGI Initial Value.

                    (C) In the event that the CMGI Final Value is greater than
ninety percent (90%) and less than one hundred ten percent (110%) of the CMGI
Initial Value, the CMGI Lock-In Value shall be the CMGI Final Value.

               (v)  The CMGI Conversion Ratio shall be subject to equitable
adjustment in the event of any stock split, stock dividend, reverse stock split
or similar event affecting the CMGI Common Stock between the beginning of such
forty-five day period used to determine the CMGI Initial Value and the Merger
Effective Time.

          (b)  Conversion of Company Common Stock.  Each share of Company Common
               ----------------------------------
Stock issued and outstanding immediately prior to the Merger Effective Time
(other than Merger Dissenting Shares) shall be converted into and represent the
right to receive one share of Surviving Corporation Common Stock.

          (c)  Surviving Corporation Common Stock.  The Surviving Corporation
               ----------------------------------
Common Stock will have the same terms as the Company Common Stock; provided,
however, the Surviving Corporation Common Stock shall have a stated par value of
$.01 per share and any Surviving Corporation Common Stock issued in the Merger
in exchange for Company Common Stock subject to a right of repurchase in favor
of the Company shall be subject to a right of repurchase in favor of the
Surviving Corporation upon the same terms and conditions as that of the original
repurchase right.

          (d)  Cancellation of Shares.  Each share of Company Common Stock and
               ----------------------
Company Preferred Stock held in the Company's treasury immediately prior to the
Merger Effective Time shall be cancelled and retired without payment of any
consideration therefor.

          (e)  Conversion of Transitory Subsidiary Stock.  All shares of
               -----------------------------------------
Transitory Subsidiary Stock issued and outstanding immediately prior to the
Merger Effective Time shall be converted into and thereafter evidence that
number of shares of Surviving Corporation Common Stock equal to 88.083% of the
issued and outstanding Surviving Corporation Common Stock, on a fully-diluted
basis.

     1.6  Merger Dissenting Shares.
          ------------------------

                                       4
<PAGE>

          (a)  For purposes of this Agreement, "Merger Dissenting Shares" means
(i) Company Common Stock and/or Company Preferred Stock (collectively, the
"Company Shares") held as of the Merger Effective Time by a Company Shareholder
who has not voted such Company Shares in favor of the adoption of this Agreement
and the Merger and with respect to which appraisal shall have been duly demanded
and perfected in accordance with Chapter 13 of the California Law and not
effectively withdrawn or forfeited prior to the Merger Effective Time.  Merger
Dissenting Shares shall not be converted into or represent the right to receive
the Merger Shares, unless such Company Shareholder's right to appraisal shall
have ceased in accordance with Section 1309 of the California Law.  If such
Company Shareholder has so forfeited or withdrawn his, her or its right to
appraisal of Merger Dissenting Shares, then, (i) as of the occurrence of such
event, such holder's Merger Dissenting Shares shall cease to be Merger
Dissenting Shares and shall be converted into and represent the right to receive
the Merger Shares issuable in respect of such Company Shares pursuant to Section
1.5, and (ii) promptly following the occurrence of such event, CMGI shall
deliver to the Exchange Agent a certificate representing the Merger Shares to
which such holder is entitled pursuant to Section 1.5 (which shares shall be
considered Initial Merger Shares for all purposes of this Agreement) and shall
deliver to the Escrow Agent a certificate representing the remaining Merger
Shares to which such holder is entitled pursuant to Section 1.10 (which shares
shall be considered Escrow Shares for all purposes of this Agreement).

          (b)  The Company shall give CMGI (i) prompt notice of any written
demands for appraisal of any Company Shares, withdrawals of such demands, and
any other instruments that relate to such demands received by the Company and
(ii) the opportunity to direct all negotiations and proceedings with respect to
demands for appraisal under the California Law.  The Company shall not, except
with the prior written consent of CMGI, make any payment with respect to any
demands for appraisal of Company Shares or offer to settle or settle any such
demands.

     1.7  Exchange of Shares.
          ------------------

          (a)  Prior to the Merger Effective Time, CMGI shall appoint the
Exchange Agent to effect the exchange for the Initial Merger Shares of
certificates that, immediately prior to the Merger Effective Time, represented
Company Shares converted into Merger Shares pursuant to Section 1.5 (including
any Company Shares referred to in the last sentence of Section 1.6(a)).  On the
Merger Closing Date, CMGI shall deliver to the Exchange Agent, in trust for the
benefit of holders of such certificates, a stock certificate (issued in the name
of the Exchange Agent or its nominee) representing the Initial Merger Shares, as
described in Section 1.5.  As soon as practicable after the Merger Effective
Time, CMGI shall cause the Exchange Agent to send a notice and a transmittal
form to each holder of a certificate advising such holder of the effectiveness
of the Merger and the procedure for surrendering to the Exchange Agent such
certificate in exchange for the Initial Merger Shares issuable pursuant to
Section 1.5.  Each holder of a certificate, upon proper surrender thereof to the
Exchange Agent in accordance with the instructions in such notice, shall be
entitled to receive in exchange therefor (subject to any taxes required to be
withheld) the Initial Merger Shares and the Surviving Corporation Common Stock
issuable pursuant to Section 1.5 plus cash in lieu of any fractional

                                       5
<PAGE>

shares, as provided in Section 1.8 below. Until properly surrendered, each such
certificate shall be deemed for all purposes to evidence only the right to
receive a certificate for the Initial Merger Shares and Surviving Corporation
Common Stock issuable pursuant to Section 1.5. Holders of certificates shall not
be entitled to receive certificates for the Initial Merger Shares and Surviving
Corporation Common Stock to which they would otherwise be entitled until such
certificates are properly surrendered.

          (b)  If any Initial Merger Shares are to be issued in the name of a
person other than the person in whose name the certificate surrendered in
exchange therefor is registered, it shall be a condition to the issuance of such
Initial Merger Shares that (i) the certificate so surrendered shall be
transferable, and shall be properly assigned, endorsed or accompanied by
appropriate stock powers, (ii) such transfer shall otherwise be proper and (iii)
the person requesting such transfer shall pay to the Exchange Agent any transfer
or other taxes payable by reason of the foregoing or establish to the
satisfaction of the Exchange Agent that such taxes have been paid or are not
required to be paid.  Notwithstanding the foregoing, neither the Exchange Agent
nor any Party shall be liable to a holder of Company Shares for any Initial
Merger Shares issuable to such holder pursuant to Section 1.5 that are delivered
to a public official pursuant to applicable abandoned property, escheat or
similar laws.

          (c)  In the event any certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such certificate to be lost, stolen or destroyed, CMGI shall issue in exchange
for such lost, stolen or destroyed certificate the Initial Merger Shares
issuable in exchange therefor pursuant to Section 1.5.  The Board of Directors
of CMGI may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate to give
CMGI a bond in such sum as it may direct as indemnity against any claim that may
be made against CMGI with respect to the certificate alleged to have been lost,
stolen or destroyed.

          (d)  No dividends or other distributions that are payable to the
holders of record of CMGI Common Stock as of a date on or after the Merger
Closing Date shall be paid to shareholders of record of the Company immediately
prior to the Merger Effective Time ("Company Shareholders") entitled by reason
of the Merger to receive Initial Merger Shares until such holders surrender
their certificates for certificates representing the Merger Shares.  Upon such
surrender, CMGI shall pay or deliver to the persons in whose name the
certificates representing such Initial Merger Shares are issued any dividends or
other distributions that are payable to the holders of record of CMGI Common
Stock as of a date on or after the Merger Closing Date and which were paid or
delivered between the Merger Effective Time and the time of such surrender;
provided that no such person shall be entitled to receive any interest on such
dividends or other distributions.

          (e)  On the Merger Closing Date, the Surviving Corporation shall
deliver to the Exchange Agent, in trust for the benefit of holders of
certificates that represented Company Shares and shares of Transitory
Subsidiary, a stock certificate (issued in the name of the Exchange Agent or its
nominee) representing the Surviving Corporation Common Stock, as described in
Section 1.5.  Such certificate shall be held by the Exchange Agent until the

                                       6
<PAGE>

Contribution Closing Date (as defined below). In the event that the Contribution
does not take place on or prior to March 15, 2000, the Exchange Agent shall take
such steps as are necessary to issue to each former Company Shareholder and
Transitory Subsidiary shareholder a stock certificate evidencing his, her or its
shares of Surviving Corporation Common Stock, as described in Section 1.5.

     1.8   Fractional Shares.  No certificates or scrip representing fractional
           -----------------
Initial Merger Shares shall be issued to former Company Shareholders upon the
surrender for exchange of certificates, and such former Company Shareholders
shall not be entitled to any voting rights, rights to receive any dividends or
distributions or other rights as a stockholder of CMGI with respect to any
fractional Initial Merger Shares that would have otherwise been issued to such
former Company Shareholders. Each former Company Shareholder that would have
been entitled to receive a fractional Initial Merger Share shall receive a cash
payment equal to the CMGI Lock-In Value multiplied by the fraction of an Initial
Merger Share that such former Company Shareholder would otherwise be entitled to
receive.

     1.9   Company Options and Warrants.
           ----------------------------

           (a)  Each option to purchase Company Common Stock issued by the
Company pursuant to its stock option plans or otherwise (a "Company Option")
which is not exercised prior to the Merger Effective Time shall be converted
into an option to acquire the same number of shares of Surviving Corporation
Common Stock for the same exercise price (a "Surviving Corporation Option"). All
other terms of the Surviving Corporation Options shall remain the same as those
contained in the Company Options. The Company shall use its Reasonable Best
Efforts to obtain, prior to the Merger Closing, the consent from each holder of
a Company Option to the foregoing.

           (b)  Warrants to acquire Company Common Stock or Company Preferred
Stock (the "Warrants") in the amount specified in Section 6.2(m) hereof shall be
exercised prior to the Merger Effective Time.  Any Warrants which are not
exercised by the Merger Effective Time shall be converted into and represent the
right to receive (A) the number of shares of CMGI Common Stock determined by
multiplying the CMGI Conversion Ratio by the number of shares of Company Common
Stock into which each share of Company Preferred Stock (which would be issuable
upon the exercise of such Warrant) is convertible immediately prior to the
Merger Effective Time, rounded down to the nearest whole number, and (B) the
number of shares of Surviving Corporation Common Stock determined by multiplying
the Preferred Ratio by the number of shares of Company Common Stock into which
each share of Company Preferred Stock (which would be issuable upon the exercise
of such Warrant) is convertible immediately prior to the Merger Effective Time,
rounded up to the nearest whole number.

     1.10  Escrow.  At the Merger Closing, shares of CMGI Common Stock into
           ------
which Company Preferred Stock was converted pursuant to Section 1.5 equal to
$19,300,000 divided by the CMGI Lock-In Value, rounded down to the nearest whole
number (the "Escrow Shares"), shall be deposited into escrow (the "Escrow") and
shall be held and disposed of in accordance with the terms of the Escrow
Agreement. Company Shareholders shall be entitled to receive at the Merger
Closing the remaining shares of CMGI Common Stock into which their Company

                                       7
<PAGE>

Preferred Stock was converted pursuant to Section 1.5 (the "Initial Merger
Shares"). The Initial Merger Shares and the Escrow Shares shall together be
referred to herein as the "Merger Shares." On the Merger Closing Date, CMGI
shall deliver to the Escrow Agent a certificate (issued in the name of the
Escrow Agent or its nominee) representing the Escrow Shares, (i) to be issued
upon the attainment of certain financial and employee retention goals set forth
below and (ii) for the purpose of securing the indemnification obligations of
the Indemnifying Shareholders (as defined in Section 8.1) set forth in this
Agreement. The Escrow Shares shall be held by the Escrow Agent under the Escrow
Agreement pursuant to the terms thereof. The Escrow Shares shall be held as a
trust fund and shall not be subject to any lien, attachment, trustee process or
any other judicial process of any creditor of any party, and shall be held and
disbursed solely for the purposes and in accordance with the terms of the Escrow
Agreement and this Agreement.

          (a)  Within thirty (30) days after December 31, 2000, CMGI shall
deliver to the Shareholder Representative an income statement showing gross
revenues for the Surviving Corporation (or, if the Surviving Corporation is
merged or combined with CMGI or any other party, the gross revenues attributable
to the business of the Company) for the period from January 1, 2000 to December
31, 2000, prepared in accordance with GAAP on a basis consistent with the
accounting practices previously utilized in the preparation of CMGI's year-end
financial statements ("Gross Revenues").  CMGI shall provide the Shareholder
Representative with reasonable access to the work papers in connection with such
calculation and shall make itself available at reasonable times upon request of
the Shareholder Representative to discuss such calculations.

          (b)  If the Shareholder Representative objects to CMGI's calculation
of Gross Revenues, the Shareholder Representative shall deliver to CMGI, within
thirty (30) days after receipt of CMGI's calculation (the "Objection Period"), a
written statement describing his, her or its objection thereto. In the event
that the Shareholder Representative fails to deliver such written statement to
CMGI prior to the expiration of the Objection Period, CMGI's calculation shall
be final, conclusive and binding upon the parties hereto. In the event that the
Shareholder Representative delivers such written statement prior to the
expiration of the Objection Period, the Parties will use all reasonable efforts
to resolve any dispute. If a final resolution is not obtained within thirty (30)
days after the Shareholder Representative has delivered such written notice,
either CMGI or the Shareholder Representative may submit any remaining disputes
for resolution to a nationally-recognized accounting firm mutually agreeable to
CMGI and the Shareholder Representative (the "Selected Accountants"), which firm
shall resolve such dispute within thirty (30) days following its selection. In
resolving any dispute, the Selected Accountants shall examine only those issues
in dispute and shall not assign a value greater than the highest value claimed
by a party or lower than the lowest value claimed by a party. The Selected
Accountants' determination shall be final, binding and conclusive upon the
parties hereto. The calculation of Gross Revenues as finally revised based on
the mutual agreement of CMGI and the Shareholder Representative shall be final,
conclusive and binding upon the Parties.

          (c)  CMGI, Engage and the Shareholder Representative shall cooperate
with the Selected Accountants in all respects, including providing the Selected
Accountants with all

                                       8
<PAGE>

work papers and back-up materials used in preparation and review of their
calculations of Gross Revenues.

          (d)  All fees, expenses and costs of the Selected Accountants shall be
borne by the Party whose estimation of Gross Revenues, taking into account any
changes made prior to submission to the Selected Accountants, is farthest from
the sum of Gross Revenues as finally determined by the Selected Accountants.

          (e)  Subject to Article VIII and subsection (g) below, in the event
that either (i) Gross Revenues as finally determined is less than $12,750,000 or
(ii) as of the first anniversary of the Merger Closing Date, more than two (2)
of the employees listed on Schedule 1.10(e) (the "Key Employees") had either
                           ----------------
voluntarily terminated their employment with the Surviving Corporation (except
for Good Reason, as defined below) or had been terminated for Cause (as defined
below), CMGI shall notify the Escrow Agent to release all of the Escrow Shares
to CMGI as provided in the Escrow Agreement.  As used herein, "Good Reason"
shall mean any of the following:  (A) the employer's material breach of
employee's employment agreement or other agreement with the employer or a
material reduction in the employee's compensation level other than for Cause;
(B) the relocation of the employer's principal executive offices outside of the
San Francisco/Bay Area; (C) the requirement by the employer that the employee be
based anywhere other than the San Francisco/Bay Area; (D) the assignment of the
employee to a position with responsibilities or duties inconsistent with his or
her title or of a lesser status or degree of responsibility than his or her
prior position with the Company; or (E) any Change of Control (as defined below)
in the Surviving Corporation, in any such cases, without the employee's consent.
"Cause" shall mean:  (A) the employee's material breach of any agreement entered
into with the employer; (B) the employee's material failure to adhere to any
written employer policy consistent with such employee's position,
responsibilities and duties, if the employee has been given a reasonable
opportunity to comply with such policy or cure his or her failure to comply; (C)
the misappropriation of any of the employer's funds or material property; (D)
the conviction of, the indictment for, or the entering of a guilty plea or plea
of no contest with respect to a felony; or (E) the employee's prolonged absence
or gross dereliction of duty, after written notice and reasonable opportunity to
cure.  "Change of Control" shall mean the sale of all or substantially all of
the assets of the Surviving Corporation, or a merger, consolidation or other
business combination resulting in the holders of capital stock of the Surviving
Corporation immediately prior to such transaction holding less than fifty
percent (50%) of the capital stock of the surviving entity in such transaction;
provided, however, that any transaction in which either CMGI or any of its
Affiliates or Engage or any of its Affiliates beneficially own at least fifty
percent (50%) of the capital stock of the surviving corporation in such
transaction or of the purchasers of all or substantially all of the assets of
the surviving corporation will not constitute a Change of Control.

          (f)  Subject to subsection (g) below, in the event that both (1) Gross
Revenues as finally determined is at least $12,750,000 and (2) as of the first
anniversary of the Merger Closing Date, no more than two (2) of the Key
Employees have either voluntarily terminated their employment with the Surviving
Corporation (except for Good Reason) or been terminated for Cause, CMGI shall
notify the Escrow Agent to release a pro rata portion of the Escrow Shares
corresponding to a fraction (not to exceed 1), the numerator of which is the
actual Gross

                                       9
<PAGE>

Revenues and the denominator of which is $15,000,000, less any Shares delivered
to any Indemnified Party in satisfaction of an indemnity claim, or retained in
Escrow by the Escrow Agent pursuant to a Claim Notice or Expected Claim Notice,
under Article VIII hereof, to the Company Shareholders as provided in the Escrow
Agreement, and the remaining Escrow Shares shall be returned to CMGI by the
Escrow Agent.

           (g)  If CMGI or Engage do not provide quarterly funding to the
Surviving Corporation during calendar year 2000 equal to or greater than the
funding amounts set forth in the Company's quarterly operating forecasts during
calendar year 2000 attached as Schedule 1.10(g) (which amounts shall exclude
                               ----------------
non-cash expenses, including but not limited to, depreciation, amortization and
stock compensation, in deriving the required operating cash funding), the
Surviving Corporation shall be deemed to have achieved Gross Revenues of
$15,000,000 for the purposes of subsection (f) above; provided, however, the
receipt of any such amounts may be waived with the written consent of the
Shareholder Representative.

     1.11  Articles of Incorporation and By-laws.
           -------------------------------------

           (a)  The Articles of Incorporation of the Surviving Corporation
immediately following the Merger Effective Time shall be the same as the
Articles of Incorporation of Transitory Subsidiary immediately prior to the
Merger Effective Time, except that (1) the name of the corporation set forth
therein shall be changed to the name of the Company and (2) the identity of the
incorporator shall be deleted.

           (b)  The By-laws of the Surviving Corporation immediately following
the Merger Effective Time shall be the same as the By-laws of Transitory
Subsidiary immediately prior to the Merger Effective Time, except that the name
of the corporation set forth therein shall be changed to the name of the
Company.

     1.12  No Further Rights.  From and after the Merger Effective Time, no
           -----------------
Company Shares shall be deemed to be outstanding, and holders of certificates
shall cease to have any rights with respect thereto, except as provided herein
or by law.

     1.13  Merger Closing of Transfer Books.  At the Merger Effective Time, the
           --------------------------------
stock transfer books of the Company shall be closed and no transfer of Company
Shares shall thereafter be made. If, after the Merger Effective Time,
certificates are presented to CMGI, the Surviving Corporation or the Exchange
Agent, they shall be cancelled and exchanged for Initial Merger Shares in
accordance with Section 1.5, subject to Section 1.10 and to applicable law in
the case of Merger Dissenting Shares.

<PAGE>

     2.1  The Contribution.  Upon and subject to the terms and conditions of
          ----------------
this Agreement, holders of Surviving Corporation Common Stock shall contribute
their Surviving Corporation Common Stock to Engage in exchange for shares of
Engage Common Stock, at the Contribution Closing (as defined below) (the
"Contribution"). The Contribution is intended to qualify as a transaction under
Section 351 of the Code.

     2.2  The Contribution Closing.  The closing of the Contribution (the
          ------------------------
"Contribution Closing") shall take place at the offices of Brobeck, Phleger &
Harrison LLP at 2200 Geng Road, Palo Alto, California, commencing at 12:00 a.m.
local time on November 15, 1999, or, if all of the conditions to the obligations
of the Parties to consummate the transactions contemplated hereby have not been
satisfied or waived by such date, on such mutually agreeable later date as soon
as practicable (and in any event not later than three business days) after the
satisfaction or waiver of all conditions (excluding the delivery of any
documents to be delivered at the Contribution Closing by any of the Parties) set
forth in Article VII hereof (the "Contribution Closing Date").

     2.3  Actions at the Contribution Closing.  At the Contribution Closing:
          -----------------------------------

          (a)  the Exchange Agent shall deliver to Engage a stock certificate
for the Surviving Corporation Common Stock; and

          (b)  Engage shall deliver a certificate for the Contribution Shares
(as defined below) to the Exchange Agent in accordance with Section 2.5.

     2.4  Additional Action.  Engage may, at any time after the Contribution
          -----------------
Closing Date, take any action, including executing and delivering any document
in order to consummate the transactions contemplated by this Agreement.

     2.5  Conversion of Shares.  At the Contribution Closing Date:
          --------------------

          (a)  Conversion of Surviving Corporation Common Stock.
               ------------------------------------------------

               (i)   Each share of Surviving Corporation Common Stock issued and
outstanding immediately prior to the Contribution Closing Date shall be
converted into and represent the right to receive such number of shares of
Engage Common Stock (the "Contribution Shares") as is equal to the Engage
Conversion Ratio (as defined below); provided, however, Engage Common Stock
issued in the Contribution in exchange for Surviving Corporation Common Stock
subject to a right of repurchase in favor of the Surviving Corporation shall be
subject to a right of repurchase in favor of Engage upon the same terms and
conditions as that of the original repurchase right.

               (ii)  Engage shall, in its discretion, either assume the stock
option plans of the Surviving Corporation (as assumed from the Company in the
Merger), or substitute Engage Options (as defined below) for Surviving
Corporation Options. Each Surviving Corporation Option shall be converted into a
similar stock option to acquire such number of shares of Engage Common Stock (an
"Engage Option") as is equal to the Engage Conversion

                                      11
<PAGE>

Ratio (as defined below), with an exercise price equal to the quotient
determined by dividing the exercise price of the Surviving Corporation Option by
the Engage Conversion Ratio, rounded down to the nearest whole cent. Engage
Options shall be fully exercisable as of the Contribution Closing Date and such
shares of Engage Common Stock issuable upon exercise thereof shall be subject to
a right of repurchase by Engage at the exercise price thereof which repurchase
right shall lapse on the same schedule as provided in the original Company
Options. If Engage Options are substituted for outstanding Surviving Corporation
Options, such Engage Options will be governed by the terms of Engage's stock
option plans, provided, that such Engage Options shall preserve substantially
all the rights and benefits contained in such Surviving Corporation Options
(except that the Engage Options shall have a term of five (5) years), and if
Engage assumes Surviving Corporation stock option plans, the resulting Engage
Options will be governed by the terms of the assumed Surviving Corporation
plans.

               (iii)  The "Engage Conversion Ratio" shall be the result obtained
by dividing (A) the quotient of (i) $193,000,000 divided by (ii) the Engage
Lock-In Value (as defined below) by (B) the Total Outstanding Company Common
Stock.

               (iv)   The "Engage Lock-In Value" shall be determined as follows:

                      (A)   In the event that the average of the last reported
sale prices per share of Engage Common Stock on the Nasdaq National Market over
the forty-five (45) consecutive trading days ending on the trading day that is
two trading days prior to the Merger Effective Time (the "Engage Final Value")
is equal to or less than ninety percent (90%) of the average of the last
reported sale prices per share of Engage Common Stock on the Nasdaq National
Market over the forty-five (45) consecutive trading days (or fewer trading days
if forty-five (45) trading days have not elapsed) ending on the trading day that
is two trading days prior to the date of this Agreement (the "Engage Initial
Value"), then the Engage Lock-In Value shall be ninety percent (90%) of the
Engage Initial Value.

                      (B)   In the event that the Engage Final Value is equal to
or greater than one hundred ten percent (110%) of the Engage Initial Value, the
Engage Lock-In Value shall be one hundred ten percent (110%) of the Engage
Initial Value.

                      (C)   In the event that the Engage Final Value is greater
than ninety percent (90%) and less than one hundred ten percent (110%) of the
Engage Initial Value, the Engage Lock-In Value shall be the Engage Final Value.

          (b)  Adjustment.  The Engage Conversion Ratio shall be subject to
               ----------
equitable adjustment in the event of any stock split, stock dividend, reverse
stock split or similar event affecting the Engage Common Stock between the
beginning of such forty-five (or lesser) day period used to determine the Engage
Initial Value and the Contribution Closing Date.

     2.6  Contribution Dissenting Shares.
          ------------------------------

          (a)  For purposes of this Agreement, "Contribution Dissenting Shares"
means Surviving Corporation Common Stock held as of the Contribution Closing
Date by a former

                                      12
<PAGE>

Company Shareholder who has not voted the Company Shares to be converted into
such Surviving Corporation Common Stock or such Surviving Corporation Common
Stock, as the case may be, in favor of the adoption of this Agreement and the
Contribution and with respect to which appraisal shall have been duly demanded
and perfected in accordance with Chapter 13 of the California Law and not
effectively withdrawn or forfeited prior to the Contribution Closing Date.
Contribution Dissenting Shares shall not be converted into or represent the
right to receive the Contribution Shares, unless such former Company
Shareholder's right to appraisal shall have ceased in accordance with Section
1309 of the California Law. If such former Company Shareholder has so forfeited
or withdrawn his, her or its right to appraisal of Contribution Dissenting
Shares, then, (i) as of the occurrence of such event, such holder's Contribution
Dissenting Shares shall cease to be Contribution Dissenting Shares and shall be
converted into and represent the right to receive the Contribution Shares
issuable in respect of such Surviving Corporation Common Stock pursuant to
Section 2.5, and (ii) promptly following the occurrence of such event, Engage
shall deliver to the Exchange Agent a certificate representing the Contribution
Shares to which such holder is entitled pursuant to Section 2.5.

          (b)  The Company shall give Engage (i) prompt notice of any written
demands for appraisal of any Surviving Corporation Common Stock, withdrawals of
such demands, and any other instruments that relate to such demands received by
the Company and (ii) the opportunity to direct all negotiations and proceedings
with respect to demands for appraisal under the California Law. The Company
shall not, except with the prior written consent of CMGI, make any payment with
respect to any demands for appraisal of Surviving Corporation Common Stock or
offer to settle or settle any such demands.

     2.7  Exchange of Shares.
          ------------------

          (a)  Prior to the Contribution Closing Date, Engage shall appoint the
Exchange Agent to effect the exchange for the Contribution Shares of
certificates that, immediately prior to the Contribution Closing Date,
represented Surviving Corporation Common Stock converted into Contribution
Shares pursuant to Section 2.5.  On the Contribution Closing Date, Engage shall
deliver to the Exchange Agent, in trust for the benefit of holders of
certificates, a stock certificate (issued in the name of the Exchange Agent or
its nominee) representing the Contribution Shares, as described in Section 2.5.
Each holder of a certificate shall be entitled to receive in exchange therefor
(subject to any taxes required to be withheld) the Contribution Shares issuable
pursuant to Section 2.5 plus cash in lieu of any fractional shares, as provided
in Section 2.8 below.

          (b)  If any Contribution Shares are to be issued in the name of a
person other than the person in whose name the certificate surrendered in
exchange therefor is registered, it shall be a condition to the issuance of such
Contribution Shares that (i) the certificate so surrendered shall be
transferable, and shall be properly assigned, endorsed or accompanied by
appropriate stock powers, (ii) such transfer shall otherwise be proper and (iii)
the person requesting such transfer shall pay to the Exchange Agent any transfer
or other taxes payable by reason of the foregoing or establish to the
satisfaction of the Exchange Agent that such taxes have been paid or are not
required to be paid.  Notwithstanding the foregoing, neither the Exchange Agent
nor any Party shall be liable to a holder of Surviving Corporation Common

                                      13
<PAGE>

Stock for any Contribution Shares issuable to such holder pursuant to Section
2.5 that are delivered to a public official pursuant to applicable abandoned
property, escheat or similar laws.

           (c)  In the event any certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such certificate to be lost, stolen or destroyed, Engage shall issue in exchange
for such lost, stolen or destroyed certificate the Contribution Shares issuable
in exchange therefor pursuant to Section 2.5.  The Board of Directors of Engage
may, in its discretion and as a condition precedent to the issuance thereof,
require the owner of such lost, stolen or destroyed certificate to give Engage a
bond in such sum as it may direct as indemnity against any claim that may be
made against Engage with respect to the certificate alleged to have been lost,
stolen or destroyed.

           (d)  No dividends or other distributions that are payable to the
holders of record of Engage Common Stock as of a date on or after the
Contribution Closing Date shall be paid to holders of Surviving Corporation
Common Stock entitled by reason of the Contribution to receive Contribution
Shares until the Exchange Agent surrenders its certificate for certificates
representing the Contribution Shares.  Upon such surrender, Engage shall pay or
deliver to the persons in whose name the certificates representing such
Contribution Shares are issued any dividends or other distributions that are
payable to the holders of record of Engage Common Stock as of a date on or after
the Contribution Closing Date and which were paid or delivered between the
Contribution Closing Date and the time of such surrender; provided that no such
person shall be entitled to receive any interest on such dividends or other
distributions.

     2.8   Fractional Shares.  No certificates or scrip representing fractional
           -----------------
Contribution Shares shall be issued to holders of Surviving Corporation Common
Stock upon the surrender for exchange of certificates, and such holders shall
not be entitled to any voting rights, rights to receive any dividends or
distributions or other rights as a stockholder of Engage with respect to any
fractional Contribution Shares that would have otherwise been issued to such
holders. Each holder of Surviving Corporation Common Stock that would have been
entitled to receive a fractional Contribution Share shall receive a cash payment
equal to the Engage Lock-In Value multiplied by the fraction of an Contribution
Share that such former Company Shareholder would otherwise be entitled to
receive.

     2.9   CMGI Representations; Engage Acknowledgement.  CMGI has all requisite
           --------------------------------------------
power and authority to deliver the Surviving Corporation Common Stock to Engage.
Engage agrees and acknowledges that Engage will accept the Surviving Corporation
Common Stock from CMGI "as is" with no representations other than as provided in
this Section 2.9.

and with respect to which appraisal shall have been duly demanded and perfected
in accordance with Chapter 13 of the California Law and not effectively

his, her or its right to appraisal of Engage Merger Dissenting Shares, then, (i)
as of the occurrence of such event, such holder's Engage Merger Dissenting

represented Surviving Corporation Common Stock converted into Engage Merger
Shares pursuant to Section 2A.5 (including any Surviving Corporation Common
Stock referred to in the last sentence of Section 2A.6(a)). Each holder of a

with the instructions in such notice, shall be entitled to receive in exchange

Until properly surrendered, each such certificate shall be deemed for all

would otherwise be entitled until such certificates are properly surrendered.

payment equal to the Engage Lock-In Value multiplied by the fraction of an
Engage Merger Share that such former Surviving Corporation Shareholder would

     3.5   Subsidiaries.

of each corporation, partnership, joint venture or other entity in which the
Company has, directly or indirectly, an equity interest representing 50% or more
of the capital stock thereof or other equity interests therein (individually, a
"Subsidiary" and, collectively, the "Subsidiaries"); (ii) the number and type of
outstanding equity securities of each Subsidiary and a list of the holders
thereof; (iii) the jurisdiction of organization of each Subsidiary; (iv) the
names of the officers and directors of each Subsidiary; and (v) the
jurisdictions in which each Subsidiary is qualified or holds licenses to do
business as a foreign corporation.

           (b) Each Subsidiary is a corporation duly organized, validly existing
and in corporate and tax good standing under the laws of the jurisdiction of its
incorporation. Each Subsidiary is duly qualified to conduct business and is in
corporate and tax good standing under the laws of each jurisdiction in which the
nature of its businesses or the ownership or leasing of its properties requires
such qualification, except where the failure to be so qualified or in good
standing, individually or in the aggregate, has not had and would not reasonably
be expected to have a Company Material Adverse Effect. For purposes of this
Agreement, "Company Material Adverse Effect" means a material adverse effect on
the assets, business, condition (financial or otherwise), results of operations
or prospects of the Company and the Subsidiaries (as defined below), taken as a
whole. Each Subsidiary has all requisite power and authority to carry on the
businesses in which it is engaged and to own and use the properties owned and
used by it. The Company has delivered to CMGI or Engage complete and accurate
copies of the charter, By-laws or other organizational documents of each
Subsidiary. No Subsidiary is in default under or in violation of any provision
of its charter, By-laws or other organizational documents. All of the issued and
outstanding shares of capital stock of each Subsidiary are duly authorized,
validly issued, fully paid, nonassessable and free of preemptive rights. All
shares of each Subsidiary that are held of record or owned beneficially by
either the Company or any Subsidiary are held or owned free and clear of any
restrictions on transfer (other than restrictions under the Securities Act and
state securities laws), claims, Security Interests, options, warrants, rights,
contracts, calls, commitments, equities and demands. There are no outstanding or
authorized options, warrants, rights, agreements or commitments to which the
Company or any Subsidiary is a party or which

                                      21
<PAGE>

are binding on any of them providing for the issuance, disposition or
acquisition of any capital stock of any Subsidiary. There are no outstanding
stock appreciation, phantom stock or similar rights with respect to any
Subsidiary. There are no voting trusts, proxies or other agreements or
understandings with respect to the voting of any capital stock of any
Subsidiary.

           (c) The Company does not control directly or indirectly or have any
direct or indirect equity participation or similar interest in any corporation,
partnership, limited liability company, joint venture, trust or other business
association which is not a Subsidiary.

     3.6   Financial Statements. The Company has provided to CMGI or Engage (a)
           --------------------
the audited consolidated balance sheets and statements of income, changes in
shareholders' equity and cash flows of the Company as of December 31, 1997 and
1998 and for the periods from July 10, 1996 (inception) to December 31, 1996 and
each of the fiscal years ending December 31, 1997 and 1998; and (b) the
unaudited consolidated balance sheet and statements of income, changes in
shareholders' equity and cash flows as of and for the six months ended as of
June 30, 1999 (such balance sheet is referred to as the "Most Recent Balance
Sheet" and the date thereof is the "Most Recent Balance Sheet Date"). The Most
Recent Balance Sheet has been reviewed by the Company's accountants. Such
financial statements (collectively, the "Financial Statements") have been
prepared in accordance with United States generally accepted accounting
principles ("GAAP") applied on a consistent basis throughout the periods covered
thereby, fairly present the financial condition, results of operations and cash
flows of the Company and the Subsidiaries as of the respective dates thereof and
for the periods referred to therein and are consistent with the books and
records of the Company and the Subsidiaries; provided, however, that the
Financial Statements referred to in clause (b) above are subject to normal
recurring year-end adjustments (which will not be material) and do not include
footnotes.

     3.7   Absence of Certain Changes. Since the Most Recent Balance Sheet Date,
           --------------------------
(a) there has occurred no event or development which has had, or could
reasonably be expected to have in the future, a Company Material Adverse Effect,
and (b) neither the Company nor any Subsidiary has taken any of the actions set
forth in paragraphs (a) through (n) of Section 5.4.

     3.8   Undisclosed Liabilities. None of the Company and its Subsidiaries has
           -----------------------
any material liability (whether known or unknown, whether absolute or
contingent, whether liquidated or unliquidated and whether due or to become
due), except for (a) liabilities shown on the Most Recent Balance Sheet, (b)
liabilities which have arisen since the Most Recent Balance Sheet Date in the
Ordinary Course of Business and which are similar in nature and amount (as a
percentage of revenues) to the liabilities which arose during the comparable
period of time in the immediately preceding fiscal period and (c) contractual
and other liabilities incurred in the Ordinary Course of Business which are not
required by GAAP to be reflected on a balance sheet. For purposes of this
Section 3.8, "material" shall mean any liability equal to or greater than
$35,000.

     3.9   Tax Matters.
           -----------

compensation, payroll, profits, license, lease, service, service use, severance,
stamp, occupation, windfall profits, customs, duties, franchise and other taxes
imposed by the United States of America or any state, local or foreign
government, or any agency thereof, or other political subdivision of the United
States or any such government, and any interest, fines, penalties, assessments
or additions to tax resulting from, attributable to or incurred in connection
with any tax or any contest or dispute thereof.

               (ii)  "Tax Returns" means all reports, returns, declarations,

           (b) Each of the Company and the Subsidiaries has filed on a timely
basis all Tax Returns that it was required to file, and all such Tax Returns

Subsidiary is or has ever been a member of a group of corporations with which it
has filed (or been required to file) consolidated, combined or unitary Tax
Returns, other than a group of which only the Company and the Subsidiaries are
or were members. Each of the Company and the Subsidiaries has paid on a timely
basis all Taxes that were due and payable. The unpaid Taxes of the Company and
the Subsidiaries for tax periods through the Most Recent Balance Sheet Date do
not exceed the accruals and reserves for Taxes (excluding accruals and reserves
for deferred Taxes established to reflect timing differences between book and
Tax income) set forth on the Most Recent Balance Sheet. Neither the Company nor
any Subsidiary has any actual or potential liability for any Tax obligation of
any taxpayer (including without limitation any affiliated group of corporations
or other entities that included the Company or any Subsidiary during a prior
period) other than the Company and the Subsidiaries. All Taxes that the Company
or any Subsidiary is or was required by law to withhold or collect have been
duly withheld or collected and, to the extent required, have been paid to the
proper Governmental Entity.

           (c) The Company has delivered to CMGI or Engage complete and accurate
copies of all federal income Tax Returns, examination reports and statements of
deficiencies assessed against or agreed to by the Company or any Subsidiary
since July 10, 1996. The federal income Tax Returns of the Company and each
Subsidiary have been audited by the Internal Revenue Service or are closed by
the applicable statute of limitations for all taxable years through the taxable
year specified in Section 3.9(c) of the Disclosure Schedule. The Company

                                      23

has delivered or made available to CMGI or Engage complete and accurate copies
of all other Tax Returns of the Company and the Subsidiaries together with all
related examination reports and statements of deficiency for all periods from
and after July 10, 1996. No examination or audit of any Tax Return of the
Company or any Subsidiary by any Governmental Entity is currently in progress
or, to the knowledge of the Company, threatened or contemplated. Neither the
Company nor any Subsidiary has been informed by any jurisdiction that the
jurisdiction believes that the Company or Subsidiary was required to file any
Tax Return that was not filed. Neither the Company nor any Subsidiary has waived
any statute of limitations with respect to Taxes or agreed to an extension of
time with respect to a Tax assessment or deficiency.

           (d) Neither the Company nor any Subsidiary: (i) is a "consenting

or potential liability for any Taxes of any person (other than the Company and
its Subsidiaries) under Treasury Regulation Section 1.1502-6 (or any similar
provision of federal, state, local, or foreign law), or as a transferee or
successor, by contract, or otherwise; or (v) is or has been required to make a
basis reduction pursuant to Treasury Regulation Section 1.1502-20(b) or Treasury
Regulation Section 1.337(d)-2(b).

           (e) None of the assets of the Company or any Subsidiary: (i) is
property that is required to be treated as being owned by any other person
pursuant to the provisions of former Section 168(f)(8) of the Code; (ii) is
"tax-exempt use property" within the meaning of Section 168(h) of the Code; or
(iii) directly or indirectly secures any debt the interest on which is tax
exempt under Section 103(a) of the Code.

           (f) Neither the Company nor any Subsidiary has undergone a change in
its method of accounting resulting in an adjustment to its taxable income
pursuant to Section 481 of the Code.

           (g) Neither the Company nor any Subsidiary is or has been a member of
an Affiliated Group.

     3.10  Assets. Each of the Company and the Subsidiaries owns or leases all
           ------
tangible assets necessary for the conduct of its businesses as presently
conducted and as presently proposed to be conducted. Each such tangible asset is
free from material defects, has been maintained in accordance with normal
industry practice, is in good operating condition and repair (subject to normal

or any Subsidiary or, to the knowledge of the Company, any other party under

           (d) neither the Company nor any Subsidiary has assigned, transferred,

of 1974, as amended.

               (iii) "ERISA Affiliate" means any entity which is, or at any

the Company or a Subsidiary.

           (b) Section 3.21(b) of the Disclosure Schedule contains a complete

respects in accordance with its terms and each of the Company, the Subsidiaries
and the ERISA Affiliates has in all material respects met its obligations with
respect to such Employee Benefit Plan and has made all required contributions
thereto. The Company, each Subsidiary, each ERISA Affiliate and each Employee
Benefit Plan are in compliance in all material respects with the currently
applicable provisions of ERISA and the Code and the regulations thereunder
(including without limitation Section 4980 B of the Code, Subtitle K, Chapter
100 of the Code and Sections 601 through 608 and Section 701 et seq. of ERISA).
All filings and reports as to each Employee Benefit Plan required to have been
submitted to the Internal Revenue Service or to the United States Department of
Labor have been duly submitted. Other than as disclosed in Section 3.21(k) of
the Disclosure Schedule, the Company does not maintain any unwritten Employee
Benefit Plan which would result in an annual cost of more than $10,000.

           (c) There are no Legal Proceedings (except claims for benefits
payable in the normal operation of the Employee Benefit Plans and proceedings
with respect to qualified domestic relations orders) against or involving any
Employee Benefit Plan or asserting any rights or claims to benefits under any
Employee Benefit Plan that could give rise to any material liability.

           (d) All the Employee Benefit Plans that are intended to be qualified
under Section 401(a) of the Code have either received determination letters from
the Internal Revenue Service to the effect that such Employee Benefit Plans are
qualified and the plans and the trusts related thereto are exempt from federal

determination letters have been submitted within the time period prescribed by
the Internal Revenue Service or determination letters have not been submitted

revocation has not been threatened, and no such Employee Benefit Plan has been
amended or operated since the date of its most recent determination letter or
application therefor in any respect, and no act or omission has occurred, that
would adversely affect its qualification or materially increase its cost. Each
Employee Benefit Plan which is required to satisfy Section 401(k)(3) or Section
401(m)(2) of the Code has been tested for compliance with, and satisfies the
requirements of, Section 401(k)(3) and Section 401(m)(2) of the Code for each
plan year ending prior to the Merger Closing Date.

           (e) Neither the Company, any Subsidiary, nor any ERISA Affiliate has
ever maintained an Employee Benefit Plan subject to Section 412 of the Code or
Title IV of ERISA.

           (f) At no time has the Company, any Subsidiary or any ERISA Affiliate
been obligated to contribute to any "multiemployer plan" (as defined in Section
4001(a)(3) of ERISA).

           (g) There are no unfunded obligations under any Employee Benefit Plan
providing benefits after termination of employment to any employee of the
Company or any Subsidiary (or to any beneficiary of any such employee),
including but not limited to retiree health coverage and deferred compensation,
but excluding continuation of health coverage required to be continued under
Section 4980B of the Code or other applicable law and insurance conversion
privileges under state law.  The assets of each Employee Benefit Plan which is
funded are reported at their fair market value on the books and records of such
Employee Benefit Plan.

           (h) No act or omission has occurred and no condition exists with
respect to any Employee Benefit Plan maintained by the Company, any Subsidiary
or any ERISA Affiliate that would subject the Company, any Subsidiary or any
ERISA Affiliate to (i) any material fine, penalty, tax or liability of any kind
imposed under ERISA or the Code or (ii) any contractual indemnification or
contribution obligation protecting any fiduciary, insurer or service provider
with respect to any Employee Benefit Plan.

           (i) No Employee Benefit Plan is funded by, associated with or related
to a "voluntary employee's beneficiary association" within the meaning of
Section 501(c)(9) of the Code.

           (j) Each Employee Benefit Plan is amendable and terminable
unilaterally by the Company at any time without liability to the Company as a
result thereof and no Employee Benefit Plan, plan documentation or agreement,
summary plan description or other written communication distributed generally to
employees by its terms prohibits the Company from amending or terminating any
such Employee Benefit Plan.

           (k) Section 3.21(k) of the Disclosure Schedule discloses each: (i)
agreement with any shareholder, director, executive officer or other key
employee of the Company or any Subsidiary (A) the benefits of which are

binding the Company or any Subsidiary, including without limitation any stock
option plan, stock appreciation right plan, restricted stock plan, stock
purchase plan, severance benefit plan or Employee Benefit Plan, any of the

will be accelerated, by the occurrence of any of the transactions contemplated
by this Agreement or the value of any of the benefits of which will be
calculated on the basis of any of the transactions contemplated by this
Agreement.

action were taken immediately) constitute a breach of any of its representations
and warranties contained herein. Since the date that Engage filed its final

          ----------
Reports, as of the date of this Agreement, there is no Legal Proceeding which is
pending or, to CMGI's or Engage's knowledge, threatened against CMGI or any
subsidiary of CMGI which would reasonably be expected to have a CMGI Material
Adverse Effect or Engage Material Adverse Effect, respectively, or which in any
manner challenges or seeks to prevent, enjoin, alter or delay the transactions
contemplated by this Agreement.

     4.8  Interim Operations of Transitory Subsidiary. Transitory Subsidiary was

formed solely for the purpose of engaging in the transactions contemplated by
this Agreement and has engaged in no business activities other than as

     4.9  Brokers' Fees.  Neither CMGI, Engage nor Transitory Subsidiary has any
          -------------
liability or obligation to pay any fees or commissions to any broker, finder or
agent with respect to the transactions contemplated by this Agreement, other

     4.10 Customers and Suppliers.  No customer or supplier of CMGI or Engage,
          -----------------------
respectively, has indicated within the past year that it will stop or decrease
the rate of buying products and/or services or supplying products to CMGI or
Engage, respectively, that would have a CMGI Material Adverse Effect or Engage
Material Adverse Effect, respectively.

     4.11 Tax Matters.
           -----------

          (a) Neither CMGI nor Engage, nor a person related to CMGI or Engage
(within the meaning of Treas. Reg. (S)1.368-1(e)(3)) has any plan or intent to
redeem or acquire any of the shares of CMGI or Engage stock issued in the Merger
or the Contribution, other than (i) the possible repurchases of unvested stock
of employees, directors or consultants in connection with termination of the
employment of such employees, directors or consultants, or (ii) in accordance
with the Escrow Agreement.

          (b) Following the Merger and the Contribution, CMGI and Engage intend
to cause the Company (as the Surviving Corporation) to hold at least 90 percent
of the fair market value of its net assets and at least 70 percent of the fair
market value of its gross assets held immediately prior to the Merger.  For the
purposes of this representation, the following assets will be treated as
property held by the Company immediately prior to but not following the Merger
and Contribution: (i) assets disposed of by the Company prior or subsequent to
the Merger and in contemplation thereof (including without limitation any asset
disposed of by the Company, other than in the ordinary course of business,
pursuant to a plan or intent existing during the period ending on the
Contribution Closing Date and beginning with the commencement of negotiations
(whether formal or informal) with CMGI and Engage regarding the Merger and the
Contribution (the "Pre-Merger Period")), (ii) assets used by the Company to pay
dissenting shareholders or paid in lieu of fractional shares of stock, to pay
any other shareholders who receive cash or other property in the Merger, or to
pay other expenses or

                                      39
<PAGE>

liabilities incurred in connection with the Merger, and (iii) assets used to
make distribution, redemption or other payments in respect of Company stock or
rights to acquire such stock (including payments treated as such for tax
purposes) that are made in contemplation of the Merger and Contribution or
related thereto. Notwithstanding the foregoing, no representations are made
regarding actions or circumstances of Company arising prior to the Contribution
Closing Date to which CMGI and Engage were not a party and of which CMGI and
Engage have no knowledge.

          (c) Prior to the Merger, CMGI will own all of the issued and
outstanding stock of Transitory Subsidiary.  Transitory Subsidiary was formed
solely for the purposes of effecting the Merger and has conducted no business or
other activities, and has incurred no liabilities, except in connection with the
Merger.

          (d) Immediately following the Contribution, CMGI will be in control of
Engage.  As used herein, "Control" shall mean ownership of stock possessing at
least 80 percent of the total combined voting power of all classes of stock
entitled to vote and at least 80 percent of the total number of shares of all
other classes of stock of the Company.  For purposes of determining Control, a
person shall not be considered to own voting stock if rights to vote such stock
(or to restrict or otherwise control the voting of such stock) are held by a
third party (including a voting trust) other than an agent of such person.

          (e) Engage does not have any plan or intention, and CMGI does not have
any plan or intention to cause Engage, to issue additional Engage stock or to
repurchase any Engage stock from CMGI which would result in CMGI no longer
having Control of Engage, nor do Engage or CMGI have any plan or intention to
take any other action that would result in CMGI losing Control of the Engage.

          (f) Neither Engage nor CMGI have any plan or intention to cause the
Company to issue additional shares of stock after the Contribution, to sell any
shares of the Company held by Engage, or to take any other action that would
result in Engage losing Control of the Company.

          (g) Except as contemplated by this Agreement, neither CMGI nor Engage
has any plan or intention to liquidate the Company, to merge the Company with or
into another corporation (other than Transitory Subsidiary), or, except for
dispositions made in the ordinary course of business, to cause the Company to
sell or otherwise dispose of any of its assets or any of the assets acquired
from Transitory Subsidiary.

          (h) CMGI and Engage intend to cause the Company to either continue the
historic business of the Company or use a significant portion of its historic
business assets in a business.

          (i) There is no intercorporate indebtedness existing between the
Company and CMGI or Engage that was issued, acquired or will be settled at a
discount as a result of the Merger or the Contribution.

                                      40

          (j) Neither CMGI nor Engage, nor any subsidiary of CMGI or Engage, or
any person related to CMGI or Engage within the meaning of Treas. Reg. (S)1.368-
1(e)(3), owns or has owned during the past five years, directly or indirectly,
any shares of the stock of the Company or rights to acquire such stock.

under which they were made, not misleading, or omit to state any material fact
necessary to correct any statement in any earlier communication with respect to

          -----------------------------------------
shall use its Reasonable Best Efforts to list the Merger Shares and the
Contribution Shares, respectively, on the Nasdaq National Market.

                                      46

     5.10  Withdrawal of Form S-1.  Within five (5) business days after the date
           ----------------------
hereof, the Company shall file an application with the SEC pursuant to Rule 477
of the Securities Act for the withdrawal of its previously-filed Registration
Statement on Form S-1, and shall use its Reasonable Best Efforts to obtain the
SEC's approval of such application for withdrawal.

     5.11  Exchange of Common Stock; Agreement of Company Preferred
           --------------------------------------------------------
Stockholders; Exercise of Warrants.  The Company shall use its Reasonable Best
- ----------------------------------
Efforts to: (a) take all steps necessary to effect an exchange resulting in
shares of Company Common Stock which are not subject to a repurchase right in
favor of the Company being converted into shares of Series F Convertible
Preferred Stock; (b) obtain the written agreement of the required number of
holders of each class of the Company Preferred Stock waiving of the right of
each such class to a liquidation preference as provided for in the Company's
articles of incorporation, or the Company shall amend its articles of
incorporation to remove the liquidation preference of each such class of Company
Preferred Stock; and (c) cause all of the Warrants to be validly exercised by
the holders of the Warrants prior to the Merger Closing Date. Notwithstanding
the foregoing, prior to the Merger Effective Time, the Company shall ensure that
an aggregate of 1,500,000 shares of Company Preferred Stock shall have been
issued to either holders of Warrants upon the exercise thereof and/or holders of
Company Options upon the exercise thereof and the conversion of shares of
Company Common Stock issuable upon such exercise into shares of Series F
Preferred Stock.

     5.12  Tax Matters.  Each of the Parties shall use its Reasonable Best
           -----------
Efforts to cause the Merger to qualify as a tax-free reorganization within the
meaning of Section 368(a) of the Code and to cause the Contribution to qualify
as a transaction within the meaning of Section 351 of the Code.

     5.13  Treatment of the Merger and the Contribution for Income Tax
           -----------------------------------------------------------
Purposes.  Each of the Parties expect and intend that the Merger will qualify as
- --------
a "reorganization" within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(E)
of the Code, and that the Contribution will have no effect on such qualification
because of the express statutory approval of transfers contained in Section
368(a)(2)(C) of the Code.  In addition, each of the Parties expect and intend
that the Contribution will also constitute an exchange described in Section 351
of the Code.  Each of the Parties hereby covenants and agrees (i) to file all
Tax Returns in a manner consistent in all respects with such expectations and
intentions, (ii) not to voluntarily undertake any action outside of the ordinary
course of business which would cause the Merger not to be treated as a
reorganization or the Contribution not to be treated as an exchange described in
Section 351.

     5.14  Loan. In the event that the Merger Effective Time has not taken place
           ----
by November 19, 1999, and the Company is not in default under the terms of this
Agreement and is not insolvent or subject to any bankruptcy or insolvency
proceedings under federal or state law, CMGI shall make a loan in the amount of
$5,000,000 to the Company (the "Loan"), evidenced by the promissory note in the
Form attached as Exhibit E hereto. The Loan shall mature one year from the date
                 ---------
thereof and shall bear interest at 14% per annum. As a condition to CMGI's
obligation to make the Loan, the Company shall have either (a) granted CMGI a
perfected first priority security interest in favor of CMGI in all of the
Company Intellectual Property, or (b)

                                      47
<PAGE>

issued to CMGI warrants to purchase a total of four percent (4%) of the Total
Outstanding Company Common Stock at an exercise price of $.01 per share, which
warrants shall be exercisable by CMGI upon the occurrence of any default, or
event that with the giving of notice or the passage of time would constitute a
default, under the Loan. In the event that the Company terminates this Agreement
pursuant to Section 10.1(c), 10.1(e) or 10.1(g) (only insofar as it relates to a
failure of a condition precedent contained in Section 6.1 (c) and/or (e), or
Section 6.3 (but not Section 6.3(c) insofar as it relates to Sections 4.6, 4.7
or 4.10)), the Company's obligation to repay the Loan shall be forgiven as
liquidated damages.

     5.15  Dilution of Shareholder Support Agreements.  If, at any time after
           ------------------------------------------
the date of this Agreement, a sufficient number of Company Options are exercised
(or the Company learns that such Company Options will be exercised by the
optionees) which results or would result in the Company Shareholders who have
signed a Shareholder Support Agreement pursuant to Section 5.3(f) above (the
"Signing Shareholders") holding an aggregate of less than a majority of the
Total Outstanding Company Common Stock, the Company shall ensure that some or
all of the Signing Shareholders exercise Company Options in an amount sufficient
to result in the Signing Shareholders holding an aggregate of not less than a
majority of the Total Outstanding Company Common Stock.

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

  Subject to Section 8.4 below, the Company Shareholders receiving the Merger
Shares pursuant to Section 1.5 (the "Indemnifying Shareholders") shall severally
indemnify each of CMGI, Engage and their respective directors, officers,
employees and Affiliates (collectively, the "CMGI Indemnified Parties") in

other liabilities (whether absolute, accrued, contingent, fixed or otherwise, or

<PAGE>

          (a) any misrepresentation, breach of warranty or failure to perform

Company Certificate;

          (b) any failure of any Company Shareholder to have good, valid and
marketable title to the issued and outstanding Company Shares issued in the name
of such Company Shareholder, free and clear of all Security Interests that would
prohibit the exchange of Company Shares in the Merger or the contribution of the
Surviving Corporation Common Stock in the Contribution, or would prevent CMGI or
Engage from having good, valid and marketable title to the issued and
outstanding Company Shares;

          (c) any claim by a shareholder or former shareholder of the Company,

     8.2  Indemnification Claims.
          ----------------------

          (a) A party entitled, or seeking to assert rights, to indemnification
under this Article VIII (an "Indemnified Party") shall give written notification
to the party from whom indemnification is sought (an "Indemnifying Party") of
the commencement of any suit or proceeding relating to a third party claim for
which indemnification pursuant to this Article VIII may be sought.  Such
notification shall be given within twenty (20) business days after receipt by
the Indemnified Party of notice of such suit or proceeding, and shall describe
in reasonable detail (to the extent known by the Indemnified Party) the facts
constituting the basis for such suit or proceeding and the amount of the claimed
damages; provided, however, that no delay on the part of the Indemnified Party
in notifying the Indemnifying Party shall relieve the Indemnifying Party of any
liability or obligation hereunder except to the extent of any damage or
liability caused by or arising out of such failure.  Within 20 days after
delivery of such notification, the Indemnifying Party may, upon written notice
thereof to the Indemnified Party, assume control of the defense of such suit or
proceeding with counsel reasonably satisfactory to the Indemnified Party;
provided that (i) the Indemnifying Party may only assume control of such defense
if (A) it acknowledges in writing to the Indemnified Party that any damages,
fines, costs or other liabilities that may be assessed against the Indemnified
Party in connection with such suit or proceeding constitute Damages for which
the Indemnified Party shall be indemnified pursuant to this Article VIII and (B)
the ad damnum is less than or equal to the amount of Damages for which the
Indemnifying Party is liable under this Article VIII and (ii) the Indemnifying
Party may

                                      53
<PAGE>

not assume control of the defense of a suit or proceeding, or any portion of a
suit or proceeding, involving criminal liability or in which equitable relief is
sought against the Indemnified Party. If the Indemnifying Party does not so
assume control of such defense, the Indemnified Party shall control such
defense. The party not controlling such defense (the "Non-controlling Party")
may participate therein at its own expense; provided that if the Indemnifying
Party assumes control of such defense and the Indemnified Party reasonably
concludes that the Indemnifying Party and the Indemnified Party have conflicting
interests or different defenses available with respect to such suit or
proceeding, the reasonable fees and expenses of counsel to the Indemnified Party
shall be considered "Damages" for purposes of this Agreement. The party
controlling such defense (the "Controlling Party") shall keep the Non-
controlling Party advised of the status of such suit or proceeding and the
defense thereof and shall consider in good faith recommendations made by the
Non-controlling Party with respect thereto. The Non-controlling Party shall
furnish the Controlling Party with such information as it may have with
respect to such suit or proceeding (including copies of any summons, complaint
or other pleading which may have been served on such party and any written
claim, demand, invoice, billing or other document evidencing or asserting the
same) and shall otherwise reasonably cooperate with and assist the Controlling
Party in the defense of such suit or proceeding. The Indemnifying Party shall
not agree to any settlement of, or the entry of any judgment arising from, any
such suit or proceeding without the prior written consent of the Indemnified
Party, which shall not be unreasonably withheld or delayed; provided that the
consent of the Indemnified Party shall not be required if the Indemnifying Party
agrees in writing to pay any amounts payable pursuant to such settlement or
judgment and such settlement or judgment includes a complete release of the
Indemnified Party from further liability and has no other adverse effect on the
Indemnified Party. The Indemnified Party shall not agree to any settlement of,
or the entry of any judgment arising from, any such suit or proceeding without
the prior written consent of the Indemnifying Party, which shall not be
unreasonably withheld or delayed.

          (b) In order to seek indemnification under this Article VIII, an
Indemnified Party shall give written notification (a "Claim Notice") to the
Indemnifying Party which contains (i) a description and the amount (the "Claimed
Amount") of any Damages incurred or reasonably expected to be incurred by the
Indemnified Party, (ii) a statement that the Indemnified Party is entitled to
indemnification under this Article VIII for such Damages and a reasonable
explanation of the basis therefor, and (iii) a demand for payment (in the manner
provided in paragraph (c) below) in the amount of such Damages.  If the
Indemnified Party is seeking to enforce such claim pursuant to the Escrow
Agreement, the Indemnifying Party shall deliver a copy of the Claim Notice to
the Escrow Agent.

          (c) Within 20 days after delivery of a Claim Notice, the Indemnifying
Party shall deliver to the Indemnified Party a written response (the "Response")
in which the Indemnifying Party shall:  (i) agree that the Indemnified Party is
entitled to receive all of the Claimed Amount (in which case the Response shall
be accompanied by a payment by the Indemnifying Party to the Indemnified Party
of the Claimed Amount, by check or by wire transfer; provided that if the
Indemnified Party is seeking to enforce such claim pursuant to the Escrow
Agreement, the Indemnifying Party and the Indemnified Party shall deliver to the
Escrow Agent, within three days following the delivery of the Response, a
written notice executed by

                                      54
<PAGE>

both parties instructing the Escrow Agent to distribute to CMGI such number of
Escrow Shares as have an aggregate Value (as defined below) equal to the Claimed
Amount), (ii) agree that the Indemnified Party is entitled to receive part, but
not all, of the Claimed Amount (the "Agreed Amount") (in which case the Response
shall be accompanied by a payment by the Indemnifying Party to the Indemnified
Party of the Agreed Amount, by check or by wire transfer; provided that if the
Indemnified Party is seeking to enforce such claim pursuant to the Escrow
Agreement, the Indemnifying Party and the Indemnified Party shall deliver to the
Escrow Agent, within three days following the delivery of the Response, a
written notice executed by both parties instructing the Escrow Agent to
distribute to CMGI such number of Escrow Shares as have an aggregate Value equal
to the Agreed Amount) or (iii) dispute that the Indemnified Party is entitled to
receive any of the Claimed Amount. If the Indemnifying Party in the Response
disputes its liability for all or part of the Claimed Amount, the Indemnifying
Party and the Indemnified Party shall follow the procedures set forth in Section
8.2(d) for the resolution of such dispute (a "Dispute"). For purposes of this
Article VIII, the "Value" of any Escrow Shares delivered in satisfaction of an
indemnity claim shall be the CMGI Lock-In Value and the Engage Lock-In Value,
respectively (subject to equitable adjustment in the event of any stock split,
stock dividend, reverse stock split or similar event affecting the CMGI Common
Stock or the Engage Common Stock, respectively, since the last trading day in
the period in which the CMGI Lock-In Value and the Engage Lock-In Value,
respectively, were determined), multiplied by the number of such Escrow Shares.

          (d) During the 60-day period following the delivery of a Response that
reflects a Dispute, the Indemnifying Party and the Indemnified Party shall use
good faith efforts to resolve the Dispute.  If the Dispute is not resolved
within such 60-day period, the Indemnifying Party and the Indemnified Party
shall submit the Dispute to arbitration as provided below.  Except with respect
to an action seeking specific performance or another equitable remedy, any
dispute shall be settled by arbitration in accordance with the commercial
arbitration rules of the American Arbitration Association ("AAA").  The
arbitration proceeding, including the rendering of an award, shall take place in
Boston, Massachusetts and be administered by the AAA.  The Parties agree to act
in good faith to mutually select an arbitrator.  The decision of the arbitrator
shall be binding on the Parties or their successors and any judgment rendered by
such arbitrator may be enforced by any court of competent jurisdiction.  Each
Party shall bear its own expenses in connection with such arbitration unless
otherwise ordered by the arbitrator.  If the Indemnified Party is seeking to
enforce the claim that is the subject of the Dispute pursuant to the Escrow
Agreement, the Indemnifying Party and the Indemnified Party shall deliver to the
Escrow Agent, promptly following the resolution of the Dispute (whether by
mutual agreement, pursuant to arbitration, as a result of a judicial decision or
otherwise), a written notice executed by both parties instructing the Escrow
Agent as to what (if any) portion of the Escrow Shares shall be distributed to
CMGI and/or the Indemnifying Shareholders (which notice shall be consistent with
the terms of the resolution of the Dispute).

          (e) Notwithstanding the other provisions of this Section 8.2, if a
third party asserts (other than by means of a lawsuit) that an Indemnified Party
is liable to such third party for a monetary or other obligation which may

to indemnification pursuant to this Article VIII, and such

Indemnified Party reasonably determines that it has a valid business reason to
fulfill such obligation, then (i) such Indemnified Party shall be entitled to
satisfy such obligation, without prior notice to or consent from the
Indemnifying Party, (ii) such Indemnified Party may subsequently make a claim
for indemnification in accordance with the provisions of this Article VIII, and
(iii) such Indemnified Party shall be reimbursed, in accordance with the
provisions of this Article VIII, for any such Damages for which it is entitled
to indemnification pursuant to this Article VIII (subject to the right of the
Indemnifying Party to dispute the Indemnified Party's entitlement to
indemnification, or the amount for which it is entitled to indemnification,
under the terms of this Article VIII); provided, however, that except with the
consent of the Shareholder Representative, no settlement of any such claim with
third party claimants shall be determinative of the amount of any claim against
the Escrow Shares.

          (f) The Shareholder Representative shall have full power and authority
on behalf of each Indemnifying Shareholder to take any and all actions on behalf
of, execute any and all instruments on behalf of, and execute or waive any and
all rights of, the Indemnifying Shareholders under this Article VIII.  The
Shareholder Representative shall have no liability to any Indemnifying
Shareholder for any action taken or omitted on behalf of the Indemnifying
Shareholders pursuant to this Article VIII.

     8.3 Survival of Representations and Warranties. All representations and
         ------------------------------------------
warranties contained in this Agreement and the Company Certificate shall (a)
survive the Merger Closing and any investigation at any time made by or on
behalf of an Indemnified Party and (b) shall expire on the date one (1) year
following the Merger Closing Date, except that (i) the representations and
warranties set forth in Sections 3.1, 3.2 and 3.3 (and the portion of the
Company Certificate relating thereto) shall survive the Merger Closing
indefinitely and (ii) the representations and warranties set forth in Sections
3.9, 3.22 and 3.23 (and the portion of the Company Certificate relating thereto)
shall survive until the expiration of all statutes of limitation applicable to
the matters referred to therein. If an Indemnified Party delivers to an
Indemnifying Party, before expiration of a representation or warranty, either a
Claim Notice based upon a breach of such representation or warranty, or a notice
that, as a result a legal proceeding instituted by or written claim made by a
third party, the Indemnified Party reasonably expects to incur Damages as a
result of a breach of such representation or warranty (an "Expected Claim
Notice"), then such representation or warranty shall survive until, but only for
purposes of, the resolution of the matter covered by such notice. If the legal
proceeding or written claim with respect to which an Expected Claim Notice has
been given is definitively withdrawn or resolved in favor of the Indemnified
Party, the Indemnified Party shall promptly so notify the Indemnifying Party;
and if the Indemnified Party has delivered a copy of the Expected Claim Notice
to the Escrow Agent and Escrow Shares have been retained in Escrow after the
Termination Date (as defined in the Escrow Agreement) with respect to such
Expected Claim Notice, the Indemnifying Party and the Indemnified Party shall
promptly deliver to the Escrow Agent a written notice executed by both parties
instructing the Escrow Agent to distribute such retained Escrow Shares to the
Indemnifying Shareholders in accordance with the terms of the Escrow Agreement.

     8.4  Limitations.

                                      56
<PAGE>

          (a) Notwithstanding anything to the contrary herein, (i) the aggregate
liability of the Indemnifying Shareholders for Damages under this Article VIII
shall not exceed the aggregate value of the Escrow Shares, (ii) the Indemnifying
Shareholders shall not be liable under Section 8.1(a) unless and until the
aggregate Damages for which they or it would otherwise be liable exceed $750,000
(at which point the Indemnifying Shareholders shall become liable for the
aggregate Damages, and not just amounts in excess of $750,000, and (iii) each
Indemnifying Shareholder shall only be liable for his, her or its pro rata share
(based on the number of Merger Shares received by such Indemnifying Shareholder
as a percentage of the total number of Merger Shares issued).

          (b) In no event will the Indemnifying Shareholders be liable for any
claims alleging incidental, consequential, special or indirect damages
(including, without limitation, any damages arising from the loss of business,
data, profits or goodwill) incurred or suffered by an Indemnified Party with
respect to this Agreement or the transactions contemplated hereby, even if the
Indemnifying Shareholders have been informed of the likelihood of such claim;
provided, however, that incidental, consequential, special or indirect damages
(including, without limitation, any damages arising from the loss of business,
data, profits or goodwill) incurred or suffered by any third-party which such
third-party is awarded from any Indemnified Party shall be considered as
"Damages" for which the Indemnified Party is liable pursuant to this Agreement.

          (c) The Escrow Agreement, among other things, is intended to secure
the indemnification obligations of the Indemnifying Shareholders under this
Agreement.

          (d) Except with respect to claims based on fraud, after the Merger
Closing, the rights of the Indemnified Parties under this Article VIII and the
Escrow Agreement shall be the exclusive remedy of the Indemnified Parties with
respect to claims resulting from or relating to any misrepresentation, breach of
warranty or failure to perform any covenant or agreement contained in this
Agreement.

          (e) No Indemnifying Shareholder shall have any right of contribution
against the Company or the Surviving Corporation with respect to any breach by
the Company of any of its representations, warranties, covenants or agreements.

     8.5  Shareholder Representative.
          --------------------------

          (a) The Shareholder Representative is hereby constituted and appointed
as agent for and on behalf of the Company Shareholders with respect to this
Article VIII.  The Shareholder Representative shall incur no liability to the
Indemnifying Shareholders with respect to any action taken or suffered by he,
she or it in reliance upon any note, direction, instruction, consent, statement
or other documents believed by he, she or it to be genuinely and duly
authorized, nor for other action or inaction except his, her or its own willful
misconduct or gross negligence.  The Shareholder Representative may, in all
questions arising under this Agreement, rely on the advice of counsel and the
Shareholder Representative shall not be liable to the Indemnifying Shareholders
for anything done, omitted or suffered in good faith by the Shareholder
Representative based on such advice.

          (b) In the event of the death or permanent disability of the
Shareholder Representative, or his, her or its resignation as an Shareholder
Representative, a successor Shareholder Representative shall be elected by a
majority vote of the Indemnifying Shareholders, with each such Indemnifying
Shareholder (or his, her or its successors or assigns) to be given a vote equal
to the number of votes represented by the shares of stock of the Company held by
such Indemnifying Shareholder immediately prior to the Merger Effective Time.
Each successor Shareholder Representative shall have all of the power,
authority, rights and privileges conferred by this Agreement upon the original
Shareholder Representative, and the term "Shareholder Representative" as used
herein shall be deemed to include successor Shareholder Representative.

          (c) The Shareholder Representative shall have full power and authority
to represent the Indemnifying Shareholders, and their successors, with respect
to all matters arising under this Article VIII and all actions taken by any
Shareholder Representative hereunder shall be binding upon the Indemnifying
Shareholders, and their successors, as if expressly confirmed and ratified in
writing by each of them.  Without limiting the generality of the foregoing, the
Shareholder Representative shall have full power and authority to interpret all
of the terms and provisions of this Article VIII, to compromise any claims
asserted hereunder and to authorize any release of the Escrow Shares to be made
with respect thereto, on behalf of the Indemnifying Shareholders and their
successors.  All actions to be taken by the Shareholder Representative hereunder
shall be evidenced by, and taken upon, the written direction of a majority
thereof.


                                   ARTICLE IX

                                    LOCK-UP

     9.1 Lock-Up. By accepting the Merger Shares, Contribution Shares and/or
         -------
Engage Merger Shares, each Company Shareholder hereby agrees as follows:

          (a) Except as otherwise provided herein, he, she or it shall not,

sell, contract to sell or otherwise sell or dispose of any of the Merger Shares
for a period of thirty (30) days following the Merger


                                      58
<PAGE>

Effective Time. After such period, the restriction on each Company Shareholder
to not offer to sell, contract to sell or otherwise sell or dispose the Merger
Shares (other than the Escrow Shares) shall lapse at the rate of one-twelfth
(1/12) of his, her or its Merger Shares (other than the Escrow Shares) per
month, commencing at the beginning of each month.

          (b) He, she or it shall not, except with the prior written approval of
Engage, directly or indirectly offer to sell, contract to sell or otherwise sell
or dispose of any of the Contribution Shares for a period of six (6) months
following the Contribution Closing Date.  He, she or it shall not, except with
the prior written approval of Engage, directly or indirectly offer to sell,
contract to sell or otherwise sell or dispose of any of the Engage Merger Shares
for a period of six (6) months following the Engage Merger Closing Date.

          (c) Subject to any other restrictions, including but not limited to,
the vesting of such shares, (i) following that date which is six (6) months
after the Contribution Closing Date, a Company Shareholder may offer to sell,
contract to sell or otherwise sell or dispose of all the Contribution Shares
held by such Company Shareholder, and (ii) following that date which is six (6)
months after the Engage Merger Closing Date, a Company Shareholder may offer to
sell, contract to sell or otherwise sell or dispose of all the Engage Merger
Shares held by such Company Shareholder.

          (d) He, she or it agrees and consents to the entry of stop transfer
instructions with CMGI's or Engage's transfer agent against the transfer of
Merger Shares, Contribution Shares or Engage Merger Shares held by the Company
Shareholder except in compliance with the foregoing restrictions.

     9.2  Exempt Transactions.  Notwithstanding the foregoing, the following
          -------------------
transactions shall be exempt from the restrictions contained in Section 9.1:
(a) the Company Shareholder may sell, assign or transfer all or any portion of
the Merger Shares, Contribution Shares or Engage Merger Shares to his or her
spouse or children, or to a trust established for the benefit of the Company
Shareholder or his or her spouse or children, or an entity owned, directly or
indirectly, by such a trust (each a "Permitted Transferee") or dispose of them
under his or her will, without compliance with this Article IX, if the
transferee agrees in writing to be subject to the terms of this Article IX to
the same extent as if such transferee were a holder of the Merger Shares,
Contribution Shares or Engage Merger Shares hereunder; and (b) any Company
Shareholder that is a partnership may sell, assign or transfer Merger Shares,
Contribution Shares or Engage Merger Shares to a partner (or a partner of a
partner) of such partnership or a retired partner (or a retired partner of a
partner) of such partnership who retires after the date of this Agreement, or to
the estate of any such partner or retired partner, without compliance with this
Article IX, if the transferee agrees in writing to be subject to the terms of
this Article IX to the same extent as if such transferee were a holder of Merger
Shares, Contribution Shares or Engage Merger Shares hereunder.  Upon the release
of any of the Escrow Shares as contemplated by this Agreement and the Escrow
Agreement, such Escrow Shares shall not be subject to the restrictions contained
in Section 9.1.

cured within 20 days following delivery by CMGI to the Company of written notice
of such breach;

Subsidiary of any representation, warranty or covenant contained in this
Agreement); or

          (g) the Company may terminate this Agreement by giving written notice
to CMGI and Transitory Subsidiary if the Merger Closing shall not have occurred

                            INTER-COMPANY AGREEMENT

     THIS INTER-COMPANY AGREEMENT (the "Agreement") is made and entered into as
of September 23, 1999 between CMGI Inc., a Delaware corporation ("CMGI"), and
Engage Technologies, Inc., a Delaware corporation and a majority-owned
subsidiary of CMGI ("Engage").

     WHEREAS, pursuant to that Agreement and Plan of Merger and Contribution
(the "Merger Agreement") entered into as of September 23, 1999 by and among
CMGI, Engage, AK Acquisition Corp., a California corporation and a wholly-owned
subsidiary of CMGI ("Transitory Subsidiary"), AdKnowledge Inc., a California
corporation (the "Company"), and Steve Findley, John Mracek and Kevin Wandryk
(collectively, the "Shareholder Representative"), CMGI and Engage contemplate:

           First, a merger of Transitory Subsidiary with and into the Company
     (the "Merger"), with the Company being the surviving corporation (the
     "Surviving Corporation"). In the Merger, (i) all the shareholders of the
     Company holding shares of Company Preferred Stock (as defined in the Merger
     Agreement) will receive (A) an aggregate of approximately $170,000,000 of
     shares of the common stock, $.01 par value par share, of CMGI ("CMGI Common
     Stock") and (B) shares of a new class of common stock of Surviving
     Corporation, $.01 par value per share ("Surviving Corporation Common
     Stock"), in exchange therefor, (ii) all the shareholders of the Company
     holding shares of the Company's common stock ("Company Common Stock") will
     receive shares of Surviving Corporation Common Stock in exchange therefor
     (the Surviving Corporation Common Stock issued under (i) and (ii) shall
     aggregate approximately 12% of the issued and outstanding Surviving
     Corporation Common Stock), and (iii) CMGI will receive Surviving
     Corporation Common Stock in exchange for the common stock, $.01 par value
     per share, of Transitory Subsidiary ("Transitory Subsidiary Stock"), in an
     aggregate amount equal to approximately 88% of the issued and outstanding
     Surviving Corporation Common Stock. The Merger is intended to qualify as a
     tax-free reorganization under Section 368(a) of the Internal Revenue Code
     of 1986, as amended (the "Code").

           Second, all the shareholders of the Surviving Corporation (including
     CMGI) will contribute their Surviving Corporation Common Stock to Engage in
     exchange for an aggregate of approximately $193,000,000 of Engage's common
     stock, $.01 par value per share ("Engage Common Stock"), in a transaction
     intended to qualify as a transaction under Section 351 of the Code (the
     "Contribution").

           Third, Engage will consummate a California short-form merger between
     the Surviving Corporation and a wholly-owned subsidiary of Engage ("Engage
     Sub"), pursuant to which Engage Sub will merge with and into the Surviving
     Corporation, with the Surviving Corporation being the surviving corporation
     in such merger and the remaining holders of Surviving Corporation Common
     Stock will receive Engage Common Stock in exchange therefor;
<PAGE>

     WHEREAS, CMGI will hold over 80% of the capital stock of Engage after
consummation of the transactions contemplated by the Merger Agreement.
     NOW, THEREFORE, in consideration of the mutual promises, covenants and
conditions hereinafter set forth and other good and valuable consideration, the
parties hereto hereby agree as follows:

     1.    Merger Agreement Transactions.
           -----------------------------

           (a)    Contribution. CMGI hereby agrees, at the Contribution Closing,
                  ------------
to contribute to Engage, and Engage hereby agrees to accept from CMGI, all
shares of Surviving Corporation Common Stock held by CMGI on the terms and
conditions outlined in the Merger Agreement.

           (b)    Merger Dissenting Shares. In the event CMGI is required to pay
                  ------------------------
any cash payments or other property to Company Shareholders arising from the
exercise of their dissenters' rights in connection with the Merger ("Appraisal
Payments"), Engage shall immediately reimburse CMGI in cash or other property,
as the case may be, for any and all such Appraisal Payments.

           (c)    Returned Escrow Shares. In the event that Escrow Shares are
                  ----------------------
released from the Escrow and delivered to CMGI pursuant to the terms of the
Merger Agreement and the Escrow Agreement (the "Returned Escrow Shares"), CMGI
shall pay to Engage in cash or other property as mutually agreed upon by the
parties a sum equal to the value of the Returned Escrow Shares, valued as
provided in Section 5 of the Escrow Agreement.

           (d)    Loan.
                  ----

                  (i)    In the event that CMGI makes the Loan to the Company
pursuant to the terms of Section 5.14 of the Merger Agreement, Engage shall
immediately upon the request of CMGI reimburse CMGI for the amount of the Loan.
Thereupon, (A) CMGI shall assign all of its rights under the promissory note
evidencing the Loan to Engage, and (B) CMGI shall assign to Engage all of CMGI's
rights under any agreements or documents evidencing its perfected first priority
security interest in the Company Intellectual Property or the warrants granted
to CMGI to purchase a total of four percent (4%) of the Total Outstanding
Company Common Stock at an exercise price of $.01 per share granted pursuant to
such Section 5.14.

                  (ii)   In the event that CMGI makes the Loan to the Company
pursuant to the terms of Section 5.14 of the Merger Agreement and Engage
reimburses CMGI for the amount of the Loan pursuant to subsection (i) above and
the Company terminates the Merger Agreement as provided in such Section 5.14
pursuant to Section 10.1(c) (insofar as it relates to CMGI or the Transitory
Subsidiary), 10.1(e) or 10.1(g) (insofar as it relates to CMGI or the Transitory
Subsidiary), and the Company's obligation to repay the Loan is forgiven as

                                LEASE AGREEMENT

     THIS LEASE AGREEMENT (the "Lease"), is made and entered into as of the day
                                -----
of October, 1999, by and between Carolina Blackhawk, LLC (the "Landlord"), and
                                                               --------
Engage Technologies, Inc., a Delaware, corporation (the "Tenant").
                                                         ------

                             W I T N E S S E T H:
                             -------------------

          1.   PREMISES AND TERM.
               -----------------

          (a)  PREMISES. In consideration of the obligation of Tenant to pay
               --------
     rent as herein provided, and in consideration of the other terms,
     provisions and covenants hereof, Landlord hereby leases to Tenant and
     Tenant hereby leases from Landlord, certain premises comprised of 24,600
     rentable square feet (the "Premises") in a building known as 3020 Highwoods
     Boulevard (the "Building") situated on certain land (the "Land") in the
                     --------                                  ----
     County of Wake, State of North Carolina, more particularly described on
     Exhibit A, attached hereto and incorporated herein by reference, together
     ---------
     with all rights, privileges, easements, appurtenances and immunities
     belonging to or in any way pertaining to the Premises.

          A floor plan of the Premises is attached hereto and made a part hereof
     as Exhibit B. Except as provided herein, the Premises are leased by Tenant
        ---------
     "as is". Except as Tenant may specify in writing to Landlord, the taking of
     possession by Tenant shall be deemed conclusively to establish that the
     Premises and any improvements thereto are in good and satisfactory
     condition as of when possession was taken. Tenant further acknowledges that
     no representations as to the repair of the Premises, nor promises to alter,
     remodel or improve the Premises have been made by Landlord unless such
     representations or promises are expressly set forth in this Lease. Within
     five days of the Commencement Date, Tenant shall, upon demand of Landlord,
     execute and deliver to Landlord a letter of acceptance of delivery of the
     Premises, acknowledging the Commencement and Termination Dates of this
     Lease.

          Before the Commencement Date (as hereinafter defined), certain upfit
     of the Premises shall be performed by Landlord and Tenant. Landlord agrees
     to perform the limited upfit set forth on Exhibit D and incorporated herein
                                               ---------
     by reference. Landlord shall also obtain at its cost the certificate of
     occupancy necessary for Tenant to occupy the Premises and conduct its
     business therein. Tenant shall be responsible for reimbursing Landlord up
     to Five Thousand Dollars ($5,000.00) for additional upfit provided Landlord
     delivers reasonable evidence that the upfit to the Premises will exceed
     $70,000.00. Tenant's reimbursement to Landlord shall be one half of any
     amount exceeding $70,000.00 but Tenant's contribution shall not exceed
     $5,000.00, which at Tenant's option shall amortize over the initial Term of
     this Lease at the rate of 8.5% per annum.

          (b)  In the event that Landlord has not substantially completed the
     Premises on or before December 31, 1999 ("Outside Date") so that Tenant can
     lawfully occupy and fully operate its business in the Premises, then Tenant
     shall have the right to terminate this Lease by written notice to Landlord
     at any time after the Outside Date but before the date that Landlord
     actually substantially completes the Premises. Notwithstanding the
     foregoing, if Landlord is delayed in performing its obligations herein, by
     reason of strike or other labor problems, acts of God, riot, weather,
     insurrection, governmental actions or requirements, activities of or
     construction by Tenant, or any other cause beyond the reasonable control of
     Landlord, the time for Landlord's performance shall be extended for the
     period of any such delay.

          Provided that Tenant and its employees, agents and contractors do not
     unreasonably interfere with Landlord's work in the Premises, Landlord shall
     allow Tenant access to the Premises to install cabling, furniture and
     equipment. Before Tenant's entry into the Premises as permitted hereunder,
     Tenant shall submit a schedule to Landlord (and Landlord's contractor, if
     so requested by Landlord), for their reasonable approval, which schedule
     shall detail the timing and purpose of Tenant's entry. Tenant shall hold
     Landlord harmless from and indemnify and protect and defend Landlord
     against any loss or damage

                                       1
<PAGE>

     to the Premises and against injury to any person caused by Tenant's actions
     as a result of such entry, to the extent such loss or damage is not covered
     by insurance carried or required to be carried under this Lease.

          Tenant acknowledges and agrees that the upfit by Landlord shall be
     performed before the Commencement Date in accordance with the plans and
     specifications for the Premises (the "Plans") (defined below) and in a good
     and workmanlike manner using standard building materials, provided such
     work is completed on or before December 31, 1999. The Plans are subject to
     the mutual and reasonable approval of Landlord and Tenant, and upon such
     approval, a copy of the Plans shall be attached hereto and made a part
     hereof as Exhibit C. Each party shall act in good faith and respond
               ---------
     promptly to any request of the other party hereto for approval of any
     portion of the Plans.

          Tenant shall have the right under this Lease, subject to any
     applicable laws, regulations or rules, including but not limited to
     Highwoods Office Park's restrictive covenants, to install satellite
     dish(es), antennas, and telecommunications equipment on the rooftop of the
     Premises at Tenant's sole cost and expense. All work by Tenant shall be
     performed in a good and workmanlike manner and in compliance with
     applicable laws and ordinances. The equipment installed by Tenant shall
     remain the exclusive property of Tenant, and Tenant shall have the right to
     remove all or any portion of said equipment at any time during the term of
     this Lease. Following any such removal, Tenant shall repair any damage
     caused by the same and restore the rooftop to its existing condition,
     reasonable wear and tear excepted. Following any termination of this Lease,
     any property which is not removed by Tenant within sixty (60) days after
     the expiration or earlier termination of this Lease shall, upon the
     expiration of said sixty (60) day period, become the property of Landlord,
     and Tenant shall thereafter have no rights, obligations or liabilities
     whatsoever with respect thereto.

          Tenant agrees to indemnify, defend and hold Landlord harmless from and
     against injury, loss, damage or liability (or any claims in respect of the
     foregoing), costs or expenses (including reasonable attorneys' fees and
     court costs) arising from the installation, use, maintenance, repair or
     removal of the equipment located on the rooftop except to the extent caused
     by Landlord's negligence or willful misconduct.

          (c)  TERM.
               ----

          TO HAVE AND TO HOLD the same for a term of thirty six (36) months
     commencing on November 1, 1999 (the "Commencement Date"), and ending on
                                          -----------------
     October 31, 2002, unless sooner terminated pursuant to the provisions
     hereof (the "Termination Date") provided, however, such Commencement Date
                  ----------------
     shall be extended for each day that the Landlord has not completed its
     upfit of the Premises in accordance with the terms hereof. The Commencement
     Date and Termination Date shall also be extended due to delays beyond the
     control of Landlord, including, but not limited to, permitting, acts of
     God, delays caused by Tenant, and/or inclement weather.

          (d)  OPTION TO RENEW.
               ---------------

          Tenant shall have the option to renew the term of the Lease for two
     renewal periods (each, a "Renewal Term") of three (3) years in duration,
                               ------------
     provided that Tenant shall not be in Default (as defined in Section 15
     hereof) under the Lease on the date such rights are exercised, or on the
     date a Renewal Term shall commence. The date of the commencement of a
     Renewal Term shall be the day after the expiration of the then current term
     of the Lease (unless sooner terminated as provided herein).

          All terms and conditions of this Lease shall be in effect during any
     Renewal Term, except that the base rent paid by Tenant during the Renewal
     Term shall be three percent (3%) above the base rent for the previous Lease
     term. Tenant shall deliver to Landlord written notice of its election to
     exercise its option to renew no less than six (6) months prior to the
     expiration of the then current Lease term or Tenant's right to renew for a
     Renewal Term shall be null and void.

          Since one of the purposes of CAM Expenses is to allow Landlord to
     require Tenant to pay for the costs attributable to its Premises, Landlord
     agrees that (i) Landlord will not collect or be entitled to collect CAM
     Expenses from all of its tenants in an amount that is in excess of one
     hundred percent (100%) of the CAM Expenses actually paid by Landlord in
     connection with the operation of the Premises, and (ii) Landlord shall make
     no profit from Landlords' collections of CAM Expenses.  All assessments and
     premiums which are not specifically charged to Tenant because of what
     Tenant has done, which can be paid by Landlord in installments, shall be
     paid by Landlord in the maximum number of installments permitted by law and
     not included as CAM Expenses except in the year in which the assessment or
     premium installment is due actually paid; provided, however, that if the
     prevailing practice in other comparable office buildings in the vicinity of
     the Building is to pay such assessments or premiums on an earlier basis,
     and Landlord pays on such basis, such assessments or premiums shall be
     included in CAM Expenses as paid by Landlord; in no event, however, shall
     Landlord include any accrued interest (resulting form such assessments or
     premiums) in its computation of CAM Expenses.

          (c)     Landlord shall keep, in the Building manager's office,
     complete books and records regarding CAM Expenses (which includes Taxes)
     (collectively, "Charges"). All records shall be retained for at least one
     (1) year. Tenant shall have the right to audit the applicable records of
     Landlord to confirm that the Charges billed to Tenant are proper and
     conform to the provisions of this Lease. Such right shall be exercisable by
     Tenant within six (6) months after Tenant's receipt of Landlord's annual
     statement of such charges. Landlord shall cooperate with Tenant in
     providing Tenant reasonable access to Landlord's books and records during
     normal business hours to enable Tenant to audit Landlord's books and
     records as they relate to any costs or expenses passed through to Tenant
     pursuant to any provisions of this Lease. If the audit discloses any
     overpayment on the

                                       5
<PAGE>

     part of Tenant, then Tenant shall be entitled to a credit on the next
     succeeding installment of rent for an amount equal to the overcharge plus
     interest on the amount of such overcharge from the date on which same was
     paid by Tenant until the date refunded by Landlord at the prime rate then
     published in The Wall Street Journal, and such credit shall be extended to
     succeeding installments of rent in the event such overcharge exceeds the
     amount of the next succeeding such installment and, in the event the term
     of this Lease has expired or been earlier terminated, then Tenant shall be
     entitled to a refund of such excess from Landlord within thirty (30) days
     after such date or expiration or earlier termination. In addition, in the
     event such audit by Tenant discloses such an overcharge in excess of five
     percent (5%) of the amount actually due from Tenant for Charges, then
     Landlord shall pay to Tenant the reasonable costs and expenses of such
     audit.

          (d)  JANITORIAL EXPENSES.
               -------------------

          Beginning on the Commencement Date and continuing for the entire term
     hereof, Tenant shall be responsible for the retention and payment of all
     janitorial services to the Premises.

          (e)  RECONCILIATION OF EXPENSES.
               --------------------------

          Within ninety (90) days of the close of each calendar year of the
     Term, Landlord shall promptly notify Tenant of the total actual CAM
     Expense, attaching a copy of the tax or special assessment bill, the
     insurance invoice, and the calculation of CAM Expense, and shall specify
     Tenant's share of the costs thereof.  Tenant shall pay the amount so
     specified to Landlord within thirty (30) days following receipt by Tenant
     of Landlord's notice.  Failure by Tenant to pay Landlord such amount within
     the period designated shall constitute a non-payment of rent by Tenant and
     a Default of Tenant's obligation under the Lease, and Landlord shall be
     entitled to all remedies provided for in this Lease upon Default in payment
     of rent. If the first year for which the CAM Expense is due or the final
     year of the term hereof do not coincide with the calendar year, Tenant's
     CAM Expense for the portion of that year shall be prorated according to the
     number of months during which Tenant was in possession of the Premises.

          (f)  SECURITY DEPOSIT.
               ----------------

          Tenant shall pay to Landlord on or before the execution date hereof
     the sum of twenty eight thousand nine hundred five and NO/100 dollars
     ($28,905.00) to be held by Landlord as security for the performance by
     Tenant of all obligations imposed on Tenant pursuant to this Lease
     (hereinafter the "security deposit"). Landlord shall not be required to
                       ----------------
     apply all or any portion of the security deposit with respect to any
     particular violation or Default by Tenant but Landlord may apply all or any
     portion of the security deposit to any violation, breach, or Default by
     Tenant hereunder. LANDLORD SHALL DEPOSIT THE SECURITY DEPOSIT IN AN
     INTEREST BEARING ESCROW ACCOUNT, WITH ALL INTEREST ACCRUED THEREON TO BE
     FOR THE BENEFIT OF LANDLORD. Tenant shall reimburse Landlord for such
     portions of the security deposit as Landlord shall from time to time apply
     with respect to any violation, breach, or Default by Tenant hereunder
     promptly upon written notice of such application by Landlord. Any portion
     of the security deposit which has not been appropriated by Landlord in
     accordance with the provisions hereof shall be returned to Tenant upon the
     termination of this Lease.

          If Landlord conveys Landlord's interest under this Lease, the
     security deposit, or any part thereof not previously applied, may be
     transferred by Landlord to Landlord's grantee, and if so transferred,
     Tenant agrees to look solely to such grantee for the proper application and
     return thereof in accordance with the terms of this Section 2.  Tenant
     agrees that Tenant will not assign, and that neither Landlord, nor its
     successors and assigns, shall be bound by any such assignment, encumbrance
     or pledge, attempted assignment, attempted pledge, or attempted encumbrance
     of the security deposit.

          Any mortgagee or ground lessor shall not be responsible to Tenant
     for the return or application of the security deposit, whether or not it
     succeeds to the position of

                                       6
<PAGE>

     Landlord hereunder, unless the security deposit shall have been received in
     fact by such mortgagee or ground lessor.

          (g)  PROVISIONS TO SURVIVE LEASE TERMINATION.
               ---------------------------------------

          Any unperformed obligations of Tenant or Landlord under this Section 2
     shall survive the termination of the Lease, for whatever reason, or any
     extension or renewal hereof.

          3.   UTILITIES.
               ---------

          (a)  Tenant shall pay all charges for all water, electrical,
     telephone, sewer, and other utilities or services used on or from the
     Premises, together with any taxes, penalties, surcharges or the like
     pertaining thereto. Tenant shall also pay for any utility maintenance
     charges and shall furnish all electric light bulbs and tubes required for
     the Premises provided the Premises will be delivered with working electric
     light bulbs and tubes. If any such services are not separately metered to
     Tenant, Tenant shall pay a reasonable proportion as determined by Landlord
     of all charges jointly metered with other tenants of the Building.

          (b)  Landlord shall in no event be liable for any interruption or
     failure of utility services on the Premises.  Landlord agrees to provide at
     its cost, all utility line connections into the Premises.

          (a)  The Premises shall be used only for the following purposes:
     general office use including without limitation computer and data centers

     the discharge of harmful gases, affluents or other wastes or toxic
     substances.  Outside storage, including, without limitation, trucks and
     other vehicles, is prohibited without Landlord's prior written consent.

     Tenant shall not permit any objectionable or unpleasant odors, smoke, dust,
     gas, noise or vibrations to permeate in or emanate from the Premises, nor

     their respective premises.  Without Landlord's prior written consent,
     Tenant shall not receive, store or otherwise handle any product, material
     or merchandise which is explosive, inflammable, combustible, corrosive,
     caustic or poisonous.  Tenant will not permit the Premises to be used for
     any purpose or in any manner (including, without limitation, any method of
     storage) which would render the insurance thereon void or the insurance
     risk more hazardous or cause the State Board of Insurance or other
     insurance authority to disallow any sprinkler credits. Tenant shall give
     notice to Landlord as soon as Tenant becomes aware of the occurrence of any
     accident in the Premises or upon Tenant's discovery of any defects thereon
     or in any fixtures or equipment located therein or upon the occurrence of
     any emergency in the Premises or the Building.

          (b)  Tenant, at its expense, in making any alterations, renovations,
     upfit or modifications of the Premises shall comply with all laws,
     ordinances, orders, rules and regulations of state, federal, municipal or
     other agencies or bodies having jurisdiction relating to the use, condition
     and occupancy of the Premises, including, but not limited to, the
     provisions of the Americans with Disabilities Act of 1990, as amended, and
     with recorded covenants, conditions and restrictions applicable for the
     Land and Building.

          (c)  Notwithstanding the foregoing or any other provision of this
     Lease, however, Tenant shall not be responsible for compliance with any
     such laws, regulations,

                                       7
<PAGE>

     or the like requiring (i) structural repairs or modifications or (ii)
     repairs or modifications to the utility or building service equipment or
     (iii) installation of new building service equipment, such as fire
     detection or suppression equipment, unless such repairs, modifications, or
     installations shall (a) be due to Tenant's particular manner of use of the
     Premises (as opposed to office use generally), or (b) be due to the
     negligence or willful misconduct of Tenant or any agent, employee, or
     contractor of Tenant.

          (d)  Landlord represents and warrants to Tenant that the reports
     attached hereto as Exhibit F include all due diligence reports received by
     Landlord in its acquisition of the Building and Land.

          (e)  Landlord represents and warrants to Tenant to the best of its
     knowledge based solely upon those reports listed on Exhibit F attached
     hereto that the Building and the Premises are in compliance with all
     applicable building code, zoning, land use and environmental laws
     including, without limitation, the Americans with Disabilities Act and
     agreements and the requirements of all easement and encumbrance documents
     and Landlord covenants to keep the same in compliance throughout the Term.

          5.   REPAIRS AND MAINTENANCE.
               -----------------------

     maintain, repair and replace only the roof, downspouts, gutters,
     foundation, all utility lines located outside the Building and the exterior
     walls, windows, glass, and plate glass of the Building in good repair,
     reasonable wear and tear excepted. Tenant shall repair, replace and pay
     for, any damage to the foregoing caused by the construction activities of
     Tenant, the negligence or willful misconduct of Tenant or Tenant's
     employees, agents or invitees, or caused by Tenant's Default hereunder.
     Tenant shall promptly give Landlord written notice of defect or need for
     repairs, after which Landlord shall have reasonable opportunity to repair
     same or cure such defect. Except to the extent caused by the willful
     misconduct or negligence of Landlord, Landlord's liability with respect to
     any defects, repairs or maintenance for which Landlord is responsible under
     any of the provisions of this Lease shall be limited to the cost of such
     repairs or maintenance or the curing of such defect.

          (b)  Tenant shall at its own cost and expense maintain and repair all
     parts of the interior of the Premises (except those for which Landlord is
     expressly responsible under the terms of this Lease) in good condition,

     special office entry, interior walls, finish work, floors and floor
     covering, plumbing work and fixtures, to the extent the foregoing are
     within the Building and regular removal of trash and debris. Tenant shall
     not be obligated to repair any casualty covered by the insurance to be
     maintained by Landlord pursuant to subparagraph 10(a) below or any systems
     or equipment under manufacturer or vendor warranty. Landlord represents and
     covenants that it will install a new heating and air conditioning system
     before December 31, 1999, at Landlord's sole cost. As such system will be
     new and under warranty, Tenant shall not be responsible for maintaining or
     repairing the same except to the extent any damage thereto is caused by the
     willful misconduct or negligence of Tenant.

          (c)  If either party hereto shall fail to fulfill its obligations
     under this paragraph 5 after written notice to the other and the passage of
     applicable cure periods, the other party hereto may enter upon the area of
     the Building or the Premises as required to conduct the obligations of the
     defaulting party, and shall be entitled to reimbursement from the
     defaulting party for its actual costs and expenses in conducting such
     obligations.  The defaulting party shall reimburse the other party hereto
     for its actual costs and expense promptly upon demand made by the other
     party hereto.  The provisions of this subparagraph shall not be interpreted
     to obligate either party hereto to conduct obligations of the other party
     hereto.

     the periodic maintenance of all heating and air conditioning systems and
     units in the Premises, and removal and replacement of filters, and shall

<PAGE>

     be with parties and upon such terms and conditions as shall be reasonably
     approved by Landlord. Tenant shall provide Landlord a copy of such
     contracts on or before the Commencement Date.

          (e)  Tenant shall not damage any demising wall of the Building, or

     demising wall caused by Tenant or its employees, agents or invitees.

          6.   ALTERATIONS.
               -----------

          (a)  Tenant shall not make any alterations, additions or improvements
     to the Premises except for minor decorative changes (including, but not
     limited to, roof and wall penetrations) without the prior written consent
     of Landlord, which may be withheld in Landlord's reasonable discretion.
     Tenant may, without the consent of Landlord, but at its own cost and
     expense and in a good workmanlike manner, make non-structural changes
     including erect such shelves, bins, machinery and trade fixtures as it may
     deem advisable, without altering the basic character or structure of the
     Premises or improvements and without overloading or damaging the Premises
     or improvements, and in each case complying with all applicable
     governmental laws, ordinances, regulations and other requirements. Tenant
     shall not make any alterations, additions or improvements to the Premises
     which will contravene Landlord's policies insuring against loss or damage
     by fire or other hazards, including but not limited to commercial general
     liability, or which will prevent Landlord from securing such policies in
     companies acceptable to Landlord. If any such alterations, additions or
     improvements cause the rate of fire or other insurance on the Premises by
     companies acceptable to Landlord to be increased beyond the minimum rate
     from time to time applicable to the Premises for permitted uses thereof,
     Tenant shall pay as additional rent the amount of any such increase
     promptly upon demand by Landlord.

          (b)  Any and all alterations, additions, improvements, partitions and
     fixtures erected by Tenant shall be the property of Landlord and shall
     remain at the Premises upon termination of the Lease or upon earlier
     vacating of the Premises. All shelves, bins, machinery and trade fixtures
     installed by Tenant may be removed by Tenant prior to the termination of
     this Lease provided such removal may be accomplished without damage to the
     Premises or to the primary structure or structural qualities of the
     Building and other improvements situated on the Premises. Tenant shall
     repair any damage to the Premises, or to the Building as a result of any
     alteration, addition, improvement, or repair to the Premises, or the
     removal of personal property or trade fixtures by Tenant, its employees,
     agents, invitees, or contractors to the Premises. Should Tenant fail to
     conduct any such repair within ten days of written notice from Landlord,
     Landlord may, at its option, perform same, and Tenant shall remit payment
     to Landlord for the actual cost and expense incurred by Landlord in
     effecting such repair immediately upon demand.

          7.   SIGNS.  Upon reasonable approval in writing by Landlord and
               ------
     subject to any applicable governmental laws, ordinances, regulations and
     other requirements (including but not limited to Highwoods Office Park's
     restrictive covenants and the City of Raleigh Code of Ordinances), Tenant
     shall have the exclusive right to install, at its sole expense, a panel
     within the monument sign located on the Premises.  The Tenant shall be
     solely responsible for the installation and maintenance of the panel within
     the monument sign. Tenant shall remove the panel upon the termination of
     this Lease.  Such installations and removals shall be made in such manner
     as to avoid injury or defacement of the Premises, and Tenant shall repair
     any injury or defacement, including, without limitation, discoloration of
     the sign box or any other related equipment regarding same caused by such
     installation and/or removal.

          8.   INSPECTION.
               -----------

          (a)  Landlord and Landlord's agents and representatives shall have
     the right to enter and inspect the Premises at any reasonable time during
     business hours, for the purpose of ascertaining the condition of the
     Premises or in order to make such repairs as may be required or permitted
     to be made by Landlord under the terms of this Lease or in

                                       9
<PAGE>

     order to show the Premises to any prospective purchaser or lender. Except
     for emergencies, Landlord shall provide 24 hours advance notice of any such
     inspection. During the period that is six (6) months prior to the end of
     the term hereof, Landlord and Landlord's agents and representatives shall
     have the right to enter the Premises at any reasonable time during business
     hours for the purpose of showing the Premises to any prospective tenant and
     shall have the right to erect on the Premises a suitable sign indicating
     the Premises are available. In all events, Landlord's entry to and
     inspection of the Premises shall be conducted so as not to interfere with
     the operation of Tenant's business in the Premises. Tenant shall schedule
     with Landlord at least thirty (30) days prior to vacating the Premises a
     time mutually agreeable to the parties hereto for a joint inspection of the
     Premises prior to vacating. In the event of Tenant's failure to give notice
     or arrange such joint inspection, Landlord's inspection made in good faith
     at or after Tenant's vacating the Premises shall be presumptively deemed
     correct for purposes of determining Tenant's responsibilities for repairs
     and restoration.

          (b)  Landlord acknowledges that Tenant's business at the Premises
     involves sensitive information and operations and the Tenant has security
     requirements to protect such information and operations.  Landlord and any
     person entering the Premises with, at the direction of or under the
     authority of, Landlord shall follow Tenant's security requirements, which
     include the requirement that all persons entering the Premises be attended
     by a representative of Tenant.  Tenant shall make a representative
     available upon 24-hours prior notice by Landlord.  In the event of an
     emergency that could cause damage to health, safety or property Landlord
     shall use good faith efforts to follow Tenant's security requirements and
     in such event Landlord will be required to give only such notice that it in
     good faith believes is feasible under the circumstances and need not wait
     to be accompanied by Tenant or its employees or representatives (although
     these parties may still accompany Landlord if they are available and wish
     to do so).

          9.   ASSIGNMENT AND SUBLETTING.  Tenant may sublet or assign the
               --------------------------             ------    ------
     Premises or the interest of Tenant therein in whole or in part without the
     consent of Landlord upon thirty (30) days written notice to Landlord to (i)
     an Affiliate (an "affiliate" shall be deemed to be any entity which is
     controlled by or under common control with Tenant or which controls
     Tenant); (ii) a Subsidiary (a "subsidiary" shall be deemed to be any entity
     controlled, directly or indirectly, by Tenant); (iii) a successor entity to
     Tenant resulting from merger, consolidation, non-bankruptcy reorganization,
     or government action; or (iv) a purchaser of all or a majority of Tenant's
     stock or assets, provided that the Building is used for general office
     purposes and/or the same or similar purpose as used by Tenant.  If such
     assignee or sublessee shall possess a net worth less than that of Tenant,
     Tenant shall continue to remain obligated under this Lease notwithstanding
     such assignment of sublease. For the purposes of this Section 9, the net
     worth of Tenant shall be measured as of the Commencement Date.

          Tenant may otherwise sublet or assign the Premises or the interest of
                               ------    ------
     Tenant therein in whole or in part, subject to the prior written consent of
     Landlord, which shall not be unreasonably withheld, so long as the Building
     is used for general office purposes and/or the same or similar purpose as
     used by Tenant. Further, except as provided herein, Tenant may not sell,
     lien, or encumber its interest in this Lease, or assign or delegate the
     management or permit the use or occupancy of the Premises in whole or in
     part by anyone other than Tenant without the prior written consent of
     Landlord, which consent Landlord may withhold in its sole discretion.
     Landlord and Tenant acknowledge and agree that the foregoing provisions
     have been freely negotiated by the parties hereto and that Landlord would
     not have entered into this Lease without Tenant's consent to the terms of
     this Paragraph 9.

          In no event shall this Lease be assignable by operation of any law,
     and Tenant's rights hereunder (to the extent permitted by law) may not
     become, and shall not be listed by Tenant as an asset under any bankruptcy,
     insolvency, or reorganization proceedings. No assignment, transfer,
     mortgage, sublease or other encumbrance, whether or not approved, and no
     indulgence granted by Landlord to any assignee or subtenant, shall in any
     way impair the continuing primary liability (which after an assignment
     shall be joint and several with the assignee) of Tenant hereunder, and no
     approval in a particular

                                       10
<PAGE>

     instance shall be deemed to be a waiver of the obligation to obtain
     Landlord's approval in any other case. If for any approved assignment or
     sublease Tenant receives rent or other consideration, either initially or
     over the term of the assignment or sublease, in excess of the base rent
     hereunder, or in case of a sublease of part of the Premises, in excess of
     the portion of such rent fairly allocable to such part, after appropriate
     adjustments to assure that all other payments called for hereunder are
     appropriately taken into account, Tenant shall pay to Landlord as
     additional rent fifty percent (50%) of the excess of each such payment of
     rent or other consideration received by Tenant promptly after its receipt.

               Notwithstanding any provision of this Lease to the contrary,
     should Tenant receive consent from Landlord to sublease or assign its
     interest in the Premises and seek to sublease or assign its interest in the
     Premises in accordance with this paragraph, Tenant shall not use the name
     of Landlord, any insignia of Landlord, or any likeness of the Building in
     any of its advertising for such sublease or assignment.

               10.  FIRE AND CASUALTY DAMAGE.
                    ------------------------

               (a)  Landlord shall obtain and keep in force a policy of general
     liability insurance with coverage against such risks and in such amounts as
     Landlord deems reasonably commercially advisable insuring Landlord against
     liability arising out of the ownership, operation and management of the
     Building. Landlord agrees to maintain standard fire and extended coverage
     insurance for the Building in an amount not less than 80% (or such greater
     percentage as may be necessary to comply with the provisions of any co-
     insurance clauses of the policy) of the "replacement cost" thereof as such
     term is defined in the Replacement Cost Endorsement to be attached thereto,
     insuring against special causes of loss, including, the perils of fire, and
     lightning, such coverages and endorsements to be as defined, provided and
     limited in the standard bureau forms prescribed by the insurance regulatory
     authority for the State of North Carolina. Subject to the provisions of
     subparagraphs 10(c), 10(d), 10(e) and Section 11 below, such insurance
     shall be for the sole benefit of Landlord and under its sole control.

               (b)  If the Premises should be damaged or destroyed by any peril
     covered by the insurance to be provided by Landlord under subparagraph
     10(a) above, Tenant shall give immediate written notice thereof to
     Landlord.

               (c)  If the Premises should be totally destroyed by any peril
     covered by the insurance to be provided by Landlord under subparagraph
     10(a) above, or if they should be so damaged thereby that rebuilding or
     repairs cannot in Landlord's estimation be completed within one hundred
     eighty (180) days after the date upon which Landlord is notified by Tenant
     of such damage, this Lease shall terminate and the rent shall be abated
     during the unexpired portion of this Lease, effective upon the date of the
     occurrence of such damage.

               (d)  If the Premises should be damaged by any peril covered by
     the insurance to be provided by Landlord under subparagraph 10(a) above,
     but only to such extent that rebuilding or repairs can, in Landlord's
     estimation, be completed within one hundred eighty (180) days after the
     date upon which Landlord is notified by Tenant of such damage, this Lease
     shall not terminate, and Landlord shall, at its sole cost and expense,
     thereupon proceed with reasonable diligence to rebuild and repair the
     Premises and the Building to substantially the condition in which they
     existed prior to such damage, except that Landlord shall not be required to
     rebuild, repair or replace any part of the partitions, fixtures, additions
     and other improvements which may have been placed in, on or about the
     Premises by Tenant. If the Premises are untenantable in whole or in part
     following such damage, the rent payable hereunder during the period in
     which they are untenantable shall be reduced in proportion to the amount of
     the Premises that is unusable or inaccessible to Tenant in the ordinary
     conduct of its business or to the extent of the interference with Tenant's
     use of the common areas of the Building.

               (e)  Notwithstanding anything herein to the contrary, in the
     event the holder of any indebtedness secured by a mortgage or deed of trust
     covering the Premises requires that the insurance proceeds be applied to
     such indebtedness, then Landlord shall have the

                                       11
<PAGE>

     right to terminate this Lease by delivering written notice of termination
     to Tenant within fifteen (15) days after such requirement is made by any
     such holder, whereupon all rights and obligations hereunder thereafter
     accruing shall cease and terminate.

               (f)  Each of Landlord and Tenant hereby waives all rights to
     recover against each other or against any other tenant or occupant of the
     Building, or against the officers, directors, shareholders, partners, joint
     venturers, employees, agents, customers, invitees, or business visitors of
     each other or of any other tenant or occupant of the Building, for any loss
     or damage arising from any cause covered by any insurance required to be
     carried by each of them pursuant to this Lease, or any other insurance
     actually carried by either of them. Landlord and Tenant shall cause their
     respective insurers to issue waiver of subrogation rights endorsements to
     all policies of insurance carried in connection with the Building or the
     Premises or the contents of either of them, and any cost for the issuance
     of such endorsements shall be borne by the original insured under such
     policies.

               (g)  The obligation of Landlord in this paragraph 10 to repair
     and restore the Premises and the Building as provided herein, does not
     include an obligation of Landlord to repair the fixtures, equipment, or
     personal property of Tenant, which Tenant shall insure for its benefit, and
     Tenant shall have the obligation to repair and restore in the event of a
     casualty or other loss.

               (h)  The period of time within which repair and restoration of
     the Premises must be completed shall be extended due to delays occasioned
     by force majeure.

               11.  LIABILITY AND INSURANCE.
                    -----------------------

               (a)  Subject to waiver of subrogation in 10(f) above, each party
     shall indemnify, defend, protect and hold the other party harmless from and
     against any and all claims, suits, judgments, losses, costs, obligations,
     damages, expenses, interests and liabilities, including, without
     limitation, reasonable attorneys' fees, for any injury or damage to any
     person or property whatsoever arising out of or in connection with the
     matters described below, when such injury or damage has been caused in
     whole or in part by the negligence or willful act of that party or its
     employees, agents or contractors. The indemnifying party shall reimburse
     the other party for any injury or damage which has been caused in whole or
     in part by the other party by reason of any breach, violation or non-
     performance by the indemnifying party, its employees, or independent
     contractors of any covenant of this Lease, or by reason of the negligence
     or willful acts of the indemnifying party, its employees or independent
     contractors. Nothing contained in this Lease shall obligate the
     indemnifying party to indemnify the other party against the other party's
     negligence or willful acts or that of its employees, agents or independent
     contractors. The provisions of this Section 11 shall survive the expiration
     or termination of this Lease and shall terminate upon the expiration of any
     applicable statute of limitations. Subject to provisions of Section 10(f),
     Tenant shall indemnify Landlord from and against any claim or loss arising
     out of any injury, loss or damage to any person or property while on or in
     the Premises, if not due to negligence or willful misconduct of Landlord or
     its employees, agents or contractors, and from damage, loss, or injury to
     any person or property anywhere occasioned by the negligence or willful
     misconduct of Tenant or of the employees, agent, independent contractors or
     invitees of Tenant. Subject to provisions of Section 20(f), Landlord shall
     indemnify Tenant from damage, loss, or injury to any person or property on
     the Premises occasioned by the negligence or willful misconduct of Landlord
     or of its employees, agents or independent contractors.

               (b)  Tenant shall not be required to indemnify and hold Landlord
     harmless from any loss, cost, liability, damage or expense, including, but
     not limited to, penalties, fines, liens, judgments, settlement costs,
     investigation costs, attorneys fees, court costs, insurance policy
     deductibles (collectively "Claims"), to any person, property or entity
     resulting from the negligence or willful misconduct of Landlord or its
     agents, contractors, servants, employees or licensees, in connection with
     the Landlord's activities on the Premises. Landlord shall not be required
     to indemnify and hold Tenant harmless from any Claims to any person,
     property or entity resulting from the negligence or willful

                                       12
<PAGE>

     misconduct of Tenant or its agents, contractors, servants, employees or
     licensees, in connection with the Tenant's activities on the Premises.

               (c)  Tenant's agreement to indemnify and hold Landlord harmless,
     the exclusion from Tenant's indemnity, Landlord's agreement to indemnify
     and hold Tenant harmless pursuant to the provisions of this Lease are not
     intended to and shall not relieve any insurance carrier of its obligations
     under policies required to be carried by Landlord or Tenant, respectively,
     pursuant to the Lease to the extent that such policies cover the results of
     such acts, omissions or willful misconduct.

               (d)  Tenant shall procure and maintain throughout the term of
     this Lease a policy or policies of insurance, at its sole cost and expense,
     naming Landlord as an additional insured, and insuring both Landlord and
     Tenant against all claims, demands or actions arising out of or in
     connection with: (i) the Premises; (ii) the condition of the Premises;
     (iii) Tenant's operations in and maintenance and use of the Premises; (iv)
     the equipment, personal property and fixtures of Tenant located on the
     Premises; (v) any interruption in the conduct of the business of Tenant on
     the Premises; (v) Tenant's liability assumed under this Lease, and such
     other kinds of insurance as Landlord shall reasonably request. The limits
     of coverage maintained by Tenant for (i) commercial general liability shall
     be not less than $5,000,000.00 with respect to each occurrence, not less
     than $5,000,000.00 with respect to personal injury or death of a single
     person, not less than $5,000,000 general aggregate, and not less than
     $5,000,000.00 with respect to products completed operations aggregate, (ii)
     for business interruption insurance shall be not less than coverage for
     actual loss, and (iii) for replacement of the equipment, personal property
     and fixtures of Tenant shall be not less than full replacement value.

               (e)  All such policies shall be procured by Tenant from
     responsible insurance companies satisfactory to Landlord. Certificates of
     insurance, together with receipt evidencing payments of premiums thereof,
     shall be delivered to Landlord prior to the Commencement Date. Not less
     than fifteen (15) days prior to the expiration date of any such policies,
     certificates of insurance (bearing notations evidencing the payment of
     renewal premiums) shall be delivered to Landlord. Such policies shall
     further provide that not less than thirty (30) days prior written notice
     shall be given to Landlord before such policy may be canceled or changed to
     reduce insurance provided thereby.

               12.  CONDEMNATION.
                    ------------

               (a)  If the whole or any substantial portion of the Premises, the
     Building or the Land should be taken for any public or quasi-public use
     under governmental law, ordinance, or regulation, or by right of eminent
     domain, or by private purchase in lieu thereof, and the taking would
     prevent or materially interfere with the use of the Premises by Tenant for
     the purposes provided herein, this Lease shall terminate and the rent shall
     be abated during the unexpired portion of this Lease, effective when the
     physical taking of the Premises shall occur.

               (b)  If a portion of the Premises, the Building or the Land shall
     be taken for any public or quasi-public use under any governmental law,
     ordinance or regulation, or by right of eminent domain, or by private
     purchase in lieu thereof, and the use by Tenant of the Premises is not
     materially interfered with, this Lease shall not terminate but the rent
     payable hereunder during the unexpired portion of this Lease shall be
     reduced in an amount that shall be reasonable under all of the
     circumstances but no less than that amount of rent relating to the portion
     of the Premises, if any, taken.

               (c)  In the event of any such taking or private purchase in lieu
     thereof, Landlord shall be entitled to receive and retain all awards as may
     be awarded in any condemnation proceedings other than those specifically
     awarded Tenant for a taking of Tenant's personal property, loss of business
     and moving expenses.

                                       13

               13.  HOLDING OVER AND TERMINATION.
                    ----------------------------

               (a)  Tenant shall upon the termination of this Lease by lapse of
     time or otherwise, yield up immediate possession to Landlord without the
     requirement of notice by Landlord to Tenant of the termination of this
     Lease, nor any grace or cure period should Tenant fail to yield up
     immediate possession to Landlord. Unless the parties hereto shall otherwise
     agree in writing, if Landlord agrees in writing that Tenant may hold over
     after the expiration or termination of this Lease, the hold over tenancy
     shall be subject to termination by Landlord at any time upon not less than
     ten (10) days advance written notice, or by Tenant at any time upon not
     less than thirty (30) days advance written notice, and all of the other
     terms and provisions of this Lease shall be applicable during that period,
     except that Tenant shall pay Landlord from time to time upon demand, as
     rental for the period of any hold over, an amount equal to one and one-half
     (1-1/2) the rent in effect on the termination date, computed on a daily
     basis for each day of the hold over period. No holding over by Tenant,
     whether with or without consent of Landlord, shall operate to extend this
     Lease except as otherwise expressly provided. The preceding provisions of
     this Paragraph 13 shall not be construed as Landlord's consent for Tenant
     to hold over.

               (b)  Upon the termination of this Lease for whatever reason,
     Tenant shall quit and immediately surrender the Premises to Landlord, broom
     clean, in good order and condition with all repairs and maintenance
     required by Tenant hereunder having been performed, ordinary wear and tear
     and casualty excepted, and Tenant shall remove its personal property from
     the Premises in accordance with this Lease.  Should any of the personal
     property or trade fixtures of Tenant remain upon the Premises after the
     Termination Date, all such property shall be deemed abandoned by Tenant,
     and Landlord may remove same at the cost and expense of Tenant with no
     liability to Tenant therefore, and Tenant hereby releases Landlord from all
     liability therefor.

               14.  QUIET ENJOYMENT.   Landlord represents and warrants that it
                    ----------------
     has full right and authority to enter into this Lease and that Tenant, upon
     paying the rental herein set forth and performing its other covenants and
     agreements herein set forth, shall peaceably and quietly have, hold and
     enjoy the Premises for the term hereof without hindrance or molestation
     from Landlord, subject to the terms and provisions of this Lease.

               15.  EVENTS OF DEFAULT.  The following events shall be deemed to
                    -----------------
     be events of Default by Tenant under this Lease:

               (a)  Tenant shall fail to pay any installment of the rent herein
     reserved, or payment with respect to taxes hereunder, or any other payment
     or reimbursement to Landlord required herein, within five (5) days after
     notice; provided, however, Tenant shall not be in default under this
     subparagraph (a) for any failure to comply with the provisions of this
     subparagraph (a) two times in any twelve month period.

               (b)  Tenant shall become insolvent, or shall make a transfer in
     fraud of creditors, or shall make an assignment for the benefit of
     creditors.

               (c)  Tenant shall file a petition under any section or chapter of
     the Bankruptcy Reform Act, as amended or under any similar law or statute
     of the United States or any state thereof; or Tenant shall be adjudged
     bankrupt or insolvent in proceedings filed against Tenant thereunder.

               (d)  A receiver or trustee shall be appointed for all or
     substantially all of the assets of Tenant.

               (e)  Tenant shall fail to yield up immediate possession of the
     Premises to Landlord upon termination of this Lease.

               (f)  Tenant shall fail to comply with any term, provision or
     covenant of this Lease (other than the provisions of subparagraphs (a),
     (b), (c), (d), and (e) of this

                                       14
<PAGE>

     Paragraph 15), and shall not cure such failure within twenty (20) days
     after written notice thereof to Tenant.

               (g)  Notwithstanding the foregoing, except for Tenant's payment
     obligations hereunder, if Tenant is delayed in performing its obligations
     hereunder, by reason of strike or other labor problems, acts of God, riot,
     insurrection, governmental actions or requirements, or any other cause
     beyond the reasonable control of Tenant, the time for Tenant's performance
     shall be extended for the period of any such delay or such longer period if
     Tenant is diligently pursuing such cure and such cure is not capable of
     being completed within twenty (20) days, provided in no event shall cure
     period be extended longer than sixty (60) days.

               16.  REMEDIES.  Upon the occurrence of any Default in Paragraph
                    ---------
     15 hereof, Landlord shall have the option to pursue any remedy at law or in
     equity, including, but not limited to, one or more of the following
     remedies without any notice or demand whatsoever:

               (a)  Terminate this Lease, in which event Tenant shall
     immediately surrender the Premises to Landlord, and if Tenant fails to do
     so, Landlord may, without prejudice to any other remedy which it may have
     for possession or arrearage in rent, enter upon and take possession of the
     Premises and expel and remove Tenant and any other person who may be
     occupying the Premises or any part thereof, with or without judicial
     approval, by any legal means necessary, without being liable for
     prosecution or any claim of damages therefor; and Tenant agrees to pay to
     Landlord on demand the amount of all loss and damage which Landlord may
     suffer by reason of such termination, whether through inability to relet
     the Premises on satisfactory terms or otherwise.

               (b)  With or without terminating this Lease, enter upon and take
     possession of the Premises and expel or remove Tenant and any other person
     who may be occupying such Premises or any part thereof, with or without
     judicial approval, by any legal means necessary, without being liable for
     prosecution and receive the rent thereof; store any property located on the
     Premises at the expense of the owner thereof and Tenant agrees to pay to
     Landlord on demand any deficiency that may arise by reason of such
     reletting. In the event Landlord is successful in reletting the Premises at
     a rental in excess of that agreed to be paid by Tenant pursuant to the
     terms of this Lease, Landlord and Tenant each mutually agree that Tenant
     shall not be entitled, under any circumstances, to such excess rental, and
     Tenant does hereby specifically waive any claim to such excess rental
     except all such rental collected shall be used to offset any damages caused
     by Tenant.

               (c)  Enter upon the Premises, with or without judicial approval,
     by any legal means necessary, without being liable for prosecution or any
     claim for damages therefor, secure the Premises against unauthorized entry,
     remove all property of Tenant from the Premises and store it at the cost
     and expense of Tenant, and do whatever Tenant is obligated to do under the
     terms of this Lease; and Tenant agrees to reimburse Landlord on demand for
     any expenses which Landlord may incur in thus effecting compliance with
     Tenant's obligations under this Lease, and Tenant further agrees that
     Landlord shall not be liable for any damages resulting to Tenant from such
     action, whether caused by the negligence of Landlord or otherwise.

               (d)  Whether or not the lease is terminated, accelerate and
     demand the payment of the present value of all base rent and other charges
     due and payable hereunder over the term of this Lease less the reasonably
     expected rent Landlord would be anticipated to collect over the remaining
     term from another tenant.

               In the event Tenant fails to pay any installment of base rent or
     additional rent hereunder within fifteen days of the due date of such
     installment, Tenant shall pay to Landlord on demand a late charge in an
     amount equal to four percent (4%) of such installment to help defray the
     additional cost to Landlord for processing such late payment.  The
     provision for such late charge shall be in addition to all of Landlord's
     other rights and remedies hereunder or at law and shall not be construed as
     liquidated damages or as limiting Landlord's remedies in any manner.  If,
     on account of any breach or default

                                       15
<PAGE>

     by Tenant in Tenant's obligations under the terms and conditions of this
     Lease, it shall become necessary or appropriate for Landlord to employ or
     consult with an attorney concerning or to enforce or defend any of
     Landlord's rights or remedies hereunder, Tenant agrees to pay any and all
     reasonable attorneys' fees so incurred.

               Pursuit of any of the foregoing remedies shall not preclude
     pursuit of any of the other remedies herein provided or any other remedies
     provided by law or equity, nor shall pursuit of any remedy herein provided
     constitute a forfeiture or waiver of any rent due to Landlord hereunder or
     of any damages accruing to Landlord by reason of the violation of any of
     the terms, provisions and covenants herein contained. No act or thing done
     by Landlord or its agents during the term hereby granted shall be deemed a
     termination of this Lease or an acceptance of the surrender of the
     Premises, and no agreement to terminate this Lease or accept a surrender of
     the Premises shall be valid unless in writing signed by Landlord. No waiver
     by either party of any violation or breach by the other party of any of the
     terms, provisions and covenants herein contained shall be deemed or
     construed to constitute a waiver of any other violation or breach of any of
     the terms, provisions and covenants herein contained. Landlord's acceptance
     of the payment of rental or other payments hereunder after the occurrence
     of an event of Default shall not be construed as a waiver of such Default,
     unless Landlord so notifies Tenant in writing, and no receipt of money by
     Landlord from Tenant after the termination of this Lease or after service
     of any notice or after the commencement of any suit or after final judgment
     for possession of the Premises shall reinstate, continue or extend the term
     of this Lease or affect any such termination, notice, suit or judgment,
     unless Landlord so notifies Tenant in writing. Forbearance by either party
     to enforce one or more of the remedies herein provided or available at law
     or in equity upon an event of default shall not be deemed or construed to
     constitute waiver of such default by the defaulting party or of the
     enforcing party's right to enforce any such remedies with respect to such
     default or any subsequent default.

               17. LANDLORD'S LIEN.  Landlord hereby waives any statutory or
                   ----------------
     contractual lien for rent in Landlord's favor, upon any and all goods,
     wares, equipment, fixtures, furniture, inventory, accounts, contract
     rights, chattel paper and other personal property of Tenant, and the
     proceeds and products thereof situated on the Premises.  Landlord hereby
     agrees to execute such certifications or statements and other instruments
     requested by Tenant evidencing the waiver of all such liens by Landlord.

               18. MORTGAGES.  Tenant accepts this Lease subject and subordinate
                   ---------
     to any mortgage(s) and/or deed(s) of trust now or at any time hereafter
     constituting a lien or charge upon the Premises or the improvements
     situated thereon; provided, however, that if the mortgagee, trustee, or
     holder of any such mortgage or deed of trust elects to have Tenant's
     interest in this Lease superior to any such instrument, then by notice to
     Tenant from such mortgagee, trustee or holder, this Lease shall be deemed
     superior to such lien, whether this Lease was executed before or after said
     mortgage or deed of trust. Tenant shall at any time hereafter on demand
     execute and provide to Landlord within ten (10) business days of a request
     therefor, any instruments, releases or other documents which may be
     required by any mortgagee or trustee for the purpose of further subjecting
     and subordinating this Lease to the lien of any such mortgage or deed to
     trust.

               Landlord shall endeavor to obtain from any existing mortgagee,
     groundlessor or other existing lien holder of the Building a so-called non-
     disturbance and attornment agreement under which Tenant's right to quiet
     possession of the Premises shall not be disturbed so long as Tenant is not
     in Default and Tenant shall pay the rent and observe and perform all of the
     provisions of this Lease, unless this Lease is otherwise terminated
     pursuant to its terms. Tenant shall not be required to subordinate this
     Lease to any future mortgagee, groundlessor or other lien holder of the
     Property unless such party agrees to enter into such a non-disturbance and
     attornment agreement with Tenant.

               19. MECHANIC'S LIENS.  Tenant shall have no authority, express
                   -----------------
     or implied, to create or place any lien or encumbrance of any kind or
     nature whatsoever upon, or in any manner to bind, the interest of Landlord
     in the Premises or to charge the rentals payable hereunder for any claim in
     favor of any person dealing with Tenant, including

                                       16
<PAGE>

     those who may furnish materials or perform labor for any construction or
     repairs, and each such claim shall affect and each such lien shall attach
     to, if at all, only the leasehold interest granted to Tenant by this
     instrument. Tenant covenants and agrees that it will pay or cause to be
     paid all sums legally due and payable by it on account of any labor
     performed or materials furnished in connection with any work performed on
     the Premises on which any lien is or can be validly and legally asserted
     against its leasehold interest in the Premises or the improvements thereon
     and that it will save and hold Landlord harmless from any and all loss,
     cost or expense based on or arising out of asserted claims or liens against
     the leasehold estate or against the right, title and interest of Landlord
     in the Premises or under the terms of this Lease.

               20.  NOTICES.  Each provision of this instrument or of any
                    -------

     enforcement of a judgment (or other judicial decree) requiring the payment
     of money by Landlord to Tenant by reason of Default or breach of Landlord

     includes any hazardous or toxic substance, pollutant, contaminant, gas, or
     petroleum product defined as such in (or for purposes of) the Comprehensive
     Environmental Response, Compensation, and Liability Act, as amended, any

     regulating, relating to, or imposing liability or standards of conduct
     concerning, any hazardous, or toxic waste, substance or material, as now or

     as copier toner, liquid paper, glue, ink and common household cleaning
     materials or materials arising in connection with the permitted uses of the

     Hazardous Material to be brought, kept, used, discharged, treated, stored,
     or disposed of in or about the Premises or the Building or Land by Tenant,
     its agents, employees, contractors or invitees.

               (c)  If Tenant knows, or has reasonable cause to believe, that it
     has caused Hazardous Material (other than Excepted Materials) or a
     condition involving or resulting from same, has come to be located in, on
     or under or about the Premises or the Building, Tenant shall promptly give
     written notice of such fact to Landlord.  Tenant shall also promptly give
     Landlord (without demand by Landlord) a copy of any statement, report,
     notice, registration, application, permit, license, given to or received
     from, any governmental authority or private party, or persons entering or
     occupying Premises, concerning the presence, spill, release, discharge of

     employ experts and/or consultants in connection with its examination of the
     Premises and with respect to the installation, operation, use, monitoring,
     maintenance, or removal of any Hazardous Materials on or from the Premises.
     The costs and expenses of any such inspections shall be paid by the party
     requesting the same.

               (e)  Tenant shall indemnify, defend, and hold Landlord, any
     parent, subsidiary and affiliate of Landlord, its officers, directors,
     beneficiaries, shareholders, partners, agents, and employees, harmless from
     all fines, suits, procedures, claims, and actions of every kind, and all
     reasonable costs associated therewith (including reasonable attorneys' and
     consultants' fees) caused by or in any way connected with any deposit,
     spill, discharge, or other release (or the threat of release) of any
     Hazardous Material or oil, or caused by the act or negligence of Tenant or
     any of Tenant's agents, employees, licensees, sublessees, concessionaires,
     contractors or invitees, (collectively, "Tenant's Acts"), or from Tenant's
     failure to provide all information, make all submissions, and take all
     actions as required by all governmental authorities under all applicable
     laws, ordinances and regulations related thereto except to the extent the
     fine, suit, procedure, claim, etc. arose due to the conduct of any third
     party or the Landlord, its officers, directors, beneficiaries,
     shareholders, partners, agents, and employees. Tenant shall not be liable,
     however, with respect to any Hazardous Materials located in the Premises
     and/or the Building as of the date hereof or introduced to the Premises
     and/or the Building other than by Tenant's acts. In addition, in connection
     with Tenant's indemnifications pursuant to this Section 24, Tenant shall be
     responsible for the reasonable cost of any remediation required to be
     performed under law in, on or to the Premises and/or the Building as a
     result of any deposit, spill, discharge, or other release (or the threat of
     release) of any Hazardous Material or oil that occurs as a result of
     Tenant's Acts. Conditions existing as of the date of this Lease are
     excluded.

                                       19
<PAGE>

               (f)  Landlord shall indemnify, defend, and hold Tenant, any
     parent, subsidiary and affiliate of Tenant, and their respective officers,
     directors, beneficiaries, shareholders, partners, agents, and employees
     harmless from all fines, suits, procedures, claims, and actions of every
     kind, and all costs associated therewith (including attorneys' and
     consultants' fees) arising out of the presence of any deposit, spill,
     discharge, or other release (or the threat of release) of any Hazardous
     Material or oil at the Premises not caused solely by Tenant's Acts or
     arising out of the presence or the act or negligence of Landlord, its
     agents, employees, or contractors (collectively, "Landlord's Acts"), or
     from Landlord's failure to provide all information, make all submissions,
     and take all actions required by all governmental authorities under all
     applicable laws, ordinances and regulations related thereto. In addition,
     in connection with Landlord's indemnifications pursuant to this Section
     24(i), Landlord shall be responsible for the cost of any remediation
     required to be performed in, on or to the Premises and/or the Building as a
     result of the matters described in this Section (f).

     at its sole cost and expense, shall cause such UPS to be removed from the
     Building in accordance with all applicable laws. The cost of such removal
     shall be excluded from CAM Expenses. There shall also be excluded from CAM
     Expenses any costs arising from management, abatement, removal or
     remediating any lead paint, asbestos or PCBs and costs arising from the
     presence of Hazardous Materials in the air, soil, surface waters or
     groundwater of the Premises except to the extent caused by Tenant Acts.

               (h)  Except as set forth in Exhibit F, Landlord has not received
     and has no knowledge of any notice, correspondence or communication from
     any third party or governmental entity regarding the environmental status
     of the Building or the Premises, including but not limited to
     communications concerning the presence of Hazardous Materials in the
     Building or at, on, or about the Premises or on the property abutting the
     Premises.

               25.  MISCELLANEOUS.
                    -------------

               (a)  Words of either gender used in this Lease shall be held and
     construed to include any other gender, and words in the singular number
     shall be held to include the plural, unless the context otherwise requires.

               (b)  The terms, provisions and covenants and conditions contained
     in this Lease shall apply to, inure to the benefit of, and be binding upon
     the parties hereto and upon their respective heirs, legal representatives,
     successors and permitted assigns, except as otherwise herein expressly
     provided. Landlord shall have the right to assign any of its rights and
     obligations under this Lease. Each party agrees to furnish to the other,
     promptly upon demand, a resolution, or other appropriate documentation
     evidencing the due authorization of such party to enter into this Lease.

               (c)  The captions inserted in this Lease are for convenience only
     and in no way define, limit or otherwise describe the scope or intent of
     this Lease, or any provision hereof, or in any way affect the
     interpretation of this Lease.

               (d)  Tenant agrees from time to time, within ten (10) business
     days after request of Landlord, to deliver to Landlord, or Landlord's
     designee, an estoppel certificate stating that this Lease is in full force
     and effect, the date to which rent has been paid, the unexpired term of
     this Lease and such other matters pertaining to this Lease as may be
     requested by Landlord. Landlord agrees from time to time, within ten (10)
     business days after request of Tenant, to deliver to Tenant, or Tenant's
     designee, an estoppel certificate stating that this Lease is in full force
     and effect, the date to which rent has been paid, the unexpired term of
     this Lease and such other matters pertaining to this Lease as may be
     requested by Tenant. It is understood and agreed that Tenant's and
     Landlord's obligation to furnish such estoppel certificates in a timely
     fashion is a material inducement for each party's execution of this Lease.

                                       20
<PAGE>

               (e)  This Lease may not be altered, changed or amended except by
     an instrument in writing signed by both parties hereto.

               (f)  All obligations of Tenant hereunder not fully performed as
     of the expiration or earlier termination of the term of this Lease shall
     survive the expiration or earlier termination of the term hereof,
     including, without limitation, all payment obligations concerning the
     condition of the Premises. Subject to casualty and normal wear and tear,
     upon the expiration or earlier termination of the term hereof, and prior to
     Tenant's vacating the Premises, Tenant shall pay to Landlord any amount
     reasonably estimated in good faith by Landlord as necessary to put the
     Premises, including, without limitation, all heating and air conditioning
     systems and equipment therein, in good condition and repair. Tenant shall
     also, prior to vacating the Premises, pay to Landlord the amount, as
     estimated by Landlord, of Tenant's pro rated obligation hereunder for real
     estate taxes and insurance premiums for the year in which the Lease expires
     or terminates. All such amounts shall be used and held by Landlord for
     payment of such obligations of Tenant hereunder, with Tenant being liable
     for any additional costs therefor upon demand by Landlord, or with any
     excess to be returned to Tenant within thirty (30) days after all such
     obligations have been determined and satisfied, as the case may be. Any
     security deposit held by Landlord shall be credited against the amount
     payable by Tenant under this Paragraph 27(f).

               (g)  In the event of a transfer by Landlord of its interest in
     the Premises, Landlord shall be released from all obligations and
     liabilities under the terms of this Lease subsequent to the date of such
     transfer. In the event a transferee shall agree to assume the obligations
     and liabilities of Landlord under the Lease prior to the date of the
     transfer, Landlord's shall be released from all obligations and liabilities
     under the Lease.

               (h)  If any clause or provision of this Lease is illegal, invalid
     or unenforceable under present or future laws effective during the term of
     this Lease, then and in that event, it is the intention of the parties
     hereto that the remainder of this Lease shall not be affected thereby, and
     it is also the intention of the parties to this Lease that in lieu of each
     clause or provision of this Lease that is illegal, invalid or
     unenforceable, there be added as a part of this Lease contract a clause or
     provision as similar in terms to such illegal, invalid or unenforceable
     clause or provision as may be possible and be legal, valid and enforceable.

               (i)  Because the Premises are on the open market and are
     presently being shown, this Lease shall be treated as an offer with the
     Premises being subject to prior lease and such offer subject to the
     withdrawal or non-acceptance by Landlord or to other use of the Premises
     without notice, and this Lease shall not be valid or binding unless and
     until both Landlord and Tenant have fully executed this Lease in writing
     and a fully executed copy delivered to both parties hereto.

               (j)  All references in this Lease to "the date hereof" or similar
     references shall be deemed to refer to the date set forth in the first
     paragraph on the first page hereof.

               (k)  Time is of the essence of this Lease.

               (l)  Landlord shall not be in Default in the performance of any
     of Landlord's obligations hereunder unless and until Landlord shall have
     failed to perform such duties or obligations within thirty (30) days (or
     such additional time as is reasonably required to correct any such Default)
     after written notice by Tenant to Landlord, and to any mortgagee with a
     lien on the Land or the Building of which Tenant has received written
     notice, properly specifying wherein Landlord has failed to perform any such
     duty or obligation. Landlord shall have no liability for any incidental or
     consequential damages of Tenant, or anyone claiming by, through or under
     Tenant, for any reason whatsoever.

               (m)  In the event that Landlord shall Default in the performance
     of Landlord's obligations hereunder, the holder of a mortgage or the
     beneficiary of a deed of trust which includes the Premises shall have the
     right, but not the obligation, to perform or comply with any covenants,
     agreements and provisions violated in connection with such Default.
     Further, if such holder or beneficiary notifies Tenant that such holder or
     beneficiary has taken over Landlord's right under this Lease, Tenant shall
     not assert any right to deduct

                                       21

     the cost of repairs or any monetary claims against Landlord theretofore
     accrued from rent thereafter due and payable, but shall look solely to
     Landlord and not such holder or beneficiary for satisfaction of such claim.

               (n)  This Lease does not create the relationship of partner or
     joint venturer between Landlord and Tenant.

               (o)  The laws of the State of North Carolina shall govern the
     interpretation, the validity, performance and enforcement of this Lease.

               (p)  The undersigned officer of Tenant does hereby warrant and
     certify to Landlord that Tenant is a corporation in good standing and duly
     organized under the laws of the State of Delaware and is authorized to do
     business in the State of North Carolina. The undersigned officer of Tenant
     hereby further warrants and certifies to Landlord that such officers are
     authorized and empowered to bind the corporation to the terms of this Lease
     by such officer's signature hereto.

               (q)  The undersigned officer of Landlord does hereby warrant and
     certify to Tenant that Landlord is a limited liability company organized
     under the laws of the State of Georgia and is in good standing under the
     laws of the State of North Carolina.  The undersigned officer of Landlord
     hereby further warrants and certifies to Tenant that such officers are
     authorized and empowered to bind the company to the terms of this Lease by
     such officer's signature hereto.

               (r)  This Lease shall be executed in duplicate, each of which
     shall be deemed an original and complete of itself and may be introduced
     into evidence or used for any purpose without the production of any other
     copy.  Duly authorized representatives of  each party must execute this
     Lease in their appropriate capacity for such party and Tenant shall affix
     its corporate seal.

               (s)  The provisions contained in the Exhibits attached hereto, if
     any, are incorporated herein by reference and made a part of this Lease.
     In the event of any conflict between the this portion of this Lease and the
     Exhibits, the provisions of the Lease shall govern and control.

               (t)  Although the provisions of this Lease were drafted by
     Landlord, such fact shall not cause this Lease to be construed either for
     or against Landlord or Tenant.

               (u)  This Lease may not be recorded.  Upon the request and at the
     expense of Tenant, Landlord shall execute a memorandum of this Lease
     suitable for recording which shall omit the financial terms herein but
     which shall identify the Premises and the term of this Lease.  Upon the
     expiration of this Lease, a recorded memorandum of this Lease may be
     canceled of record by a document executed by Landlord, or its successor in
     interest for such purpose.

               (v)  If Tenant is not a publicly traded company, Tenant shall
     provide to Landlord within ninety (90) days of the close of its fiscal
     year, and thereafter within ten days of the reasonable request of Landlord,
     financial statements of Tenant certified by the chief financial officer of
     Tenant, and Tenant shall act to ensure that any guarantor (if it is not a
     publicly traded company) hereof provides Landlord with copies of its
     financial statements within ninety days of the close of its fiscal year.

               (w)  No remedy conferred herein is intended to be exclusive of
     any other remedy and each and every remedy shall be cumulative and shall be
     in addition to every other remedy given hereunder or thereunder or now or
     hereafter existing at law or in equity or by statute or otherwise.

               (x)  No provision of this Lease shall be deemed to waive any
     statutory or common law rights of Landlord to assert a lien upon property
     of Tenant.

                                       22
<PAGE>

               (y)  An "Abatement Event" shall be defined as an event or
     circumstance that prevents Tenant from using the Premises or any portion
     thereof, as a result of any failure to provide services or access to the
     Premises.  Tenant shall give Landlord notice ("Abatement Notice") of any
     such Abatement Event, and if such Abatement Event continues beyond the
     "Eligibility Period" (as that term is defined below), then the Base Rent
     and Tenant's other monetary obligations to Landlord shall be abated
     entirely or reduced, as the case may be, after expiration of the
     Eligibility Period for such time that Tenant continues to be so prevented
     from using, and does not use, the Premises or a portion thereof, in the
     proportion that the rentable area of the portion of the Premises that
     Tenant is prevented from using, and does not use, bears to the total
     rentable area of the Premises; provided, however, in the event that Tenant
     is prevented from using, and does not use, a portion of the Premises for a
     period of time in excess of the Eligibility Period and the remaining
     portion of the Premises is not sufficient to allow Tenant to effectively
     conduct its business therein, and if Tenant does not conduct its business
     from such remaining portion, then for such time after expiration of the
     Eligibility Period during which Tenant is so prevented from effectively
     conducting its business therein, Base Rent and Tenant's other monetary
     obligations to Landlord shall be abated entirely for such time as Tenant
     continues to be so prevented from using, and does not use, the Premises.
     The term "Eligibility Period" shall mean a period of fifteen (15)
     consecutive days after Landlord's receipt of any Abatement Notice(s).  In
     addition, if an Abatement Event continues for ninety (90) consecutive days
     after an Abatement Notice, Tenant may terminate this Lease by written
     notice to Landlord at any time before the date such Abatement Event is
     cured by Landlord.

               (z)  Regardless of any reference to the words "sole" or
     "absolute" (but except for matters which will have an adverse effect on the
     (a) structural integrity of the Building (b) the Building's plumbing,
     heating, life safety, ventilating, air conditioning, mechanical or
     electrical systems, or (c) the exterior appearance of the Building,
     whereupon in each such case Landlord's duty is to act in good faith and in
     compliance with the Lease), any time the consent of Landlord or Tenant is
     required, such consent shall not be unreasonably withheld, conditioned or
     delayed. Whenever the Lease grants Landlord or Tenant the right to take
     action, exercise discretion, establish rules and regulations or make
     allocations or other determinations, Landlord and Tenant shall act
     reasonably and in good faith.

               (aa) Tenant shall have exclusive use of all parking spaces
     surrounding the Building. Landlord shall maintain all such parking areas.

               (bb) Expansion Option. Tenant will have the right to exercise an
     option (the "Expansion Option") pursuant to which Tenant and Landlord will
     exercise good faith and commercially reasonable efforts to agree on and
     accomplish an expansion of the Building by approximately 10,000 square feet
     (but in no event will this expansion cause the size of the Building to
     exceed the maximum permitted area or size of the Building as currently
     entitled under existing applicable laws unless otherwise specifically
     agreed in writing by Tenant and Landlord).  The Expansion Option can be
     exercised only by Tenant delivering to Landlord written notice of exercise
     during the first two (2) years of the Lease term.

               If Tenant validly exercises the Expansion Option, the following
     issues (and any other necessary issues) will need to be agreed on in order
     to accomplish the expansion:  the initial general form of (and, if
     agreement is reached on the other terms, the final plans and specifications
     for) the expansion and a schedule therefor; the contractors and
     professionals that will perform the work; all costs in connection with the
     expansion, including, without limitation, costs of surveys, testing,
     design, space planning, drafting, architecture engineering, other
     professional fees, labor, material, services, utilities, and other costs of
     construction, permits and approvals (and associated legal and other fees
     and costs); a mutually agreeable rental rate for the expansion space,
     taking into account all of the associated costs and a mutually agreeable
     rate of return to Landlord and its lenders; other mutually agreeable
     modifications to the Lease to accommodate the expansion, and an extension
     of the initial Lease term so that the initial Lease term for all of the
     Premises expires at least five (5) years after the rent commencement date
     of the expansion space.


                                       23
<PAGE>

               In view of the foregoing agreements that must be reached in order
     to accomplish the expansion, and because neither the necessary permits and
     approvals nor acceptable financing for the expansion and associated costs
     have been offered or obtained at this time, and because of the other
     conditions that must first be satisfied so as to permit the expansion, the
     parties agree that, notwithstanding anything to the contrary, if for any
     reason the parties do not reach terms or if any of the conditions in this
     Section are not satisfied, neither party will be deemed to be in default in
     any manner and will not incur liabilities to the other, and unless
     otherwise agreed in writing by both parties, the Expansion Option will
     lapse and become null and void, the Lease will continue in full force and
     effect in accordance with its terms without an expansion, and Tenant's
     obligations under the Lease will not be reduced, excused, waived or
     otherwise affected in any way.

               In addition to any other conditions to the Expansion Option,
     Landlord's lenders, if any, must consent in writing to the expansion.

               (cc) Landlord has performed a Y2K assessment of the Building and
     has no actual knowledge of any Y2K problems that could materially interfere
     with the functioning of the Building or Building Systems.

     IN WITNESS WHEREOF, the parties hereto have executed this Lease under seal
as of the day and year first above written.
