(1) The Company and Basis of Presentation


Description of Company

  VerticalNet, Inc. ("VerticalNet" or the "Company") is an owner and operator of
vertical trade communities, which are targeted business-to-business communities
of commerce on the Internet. The Company's vertical trade communities are Web
sites that act as industry-specific comprehensive sources of information,
interaction and electronic commerce. Vertical trade communities combine product
information; industry news; requests for proposals; directories; classifieds;
job listings; discussion forums; a variety of electronic commerce opportunities
for buyers and sellers; and other services, such as online professional
education courses and virtual trade shows. Each trade community is individually
branded, focuses on one business sector and caters to individuals with similar
professional interests. The virtual trade communities are designed to attract
technical and purchasing professionals with highly specialized product and
specification requirements and purchasing authority or influence. The Company
was founded on July 28, 1995 and as of July 30, 1999 operates 43 vertical trade
communities in ten major industry groups: environmental; advanced technologies;
service; communications; process; science; healthcare; manufacturing and metals,
food & packaging and food service/hospitality.

  On February 17, 1999, the Company completed its initial public offering (the
"IPO") of 4,025,000 shares of its common stock at $16.00 per share. Net proceeds
to the Company aggregated approximately $58,300,000 (net of underwriters'
commission and offering expenses of $6,100,000).  As of the closing date of the
offering, all of the convertible preferred stock outstanding was converted into
9,734,846 shares of common stock. In addition, the Company's $5.0 million
convertible notes were converted into 312,500 shares of common stock.

  The Company currently generates substantially all of its revenue from Internet
advertising including the development of "storefronts" (Web pages that focus on
advertisers' products and provide a link to the advertisers' Web sites).  The
advertising contracts do not extend beyond one year. Advertising revenues are
recognized ratably over the period of the advertising contract. Revenues from
educational courses are recognized in the period in which the course is
completed and revenues from the sale of books are recognized in the period in
which the books are shipped.  Auction revenues related to transaction fees are
recognized at the time that the auction is successfully concluded. All e-
commerce revenue, whether a transaction fee, a percentage of sale fee or a
minimum guaranteed fee, is recorded when earned.  Approximately $1.9 million at
June 30, 1999 and $1.0 million at December 31, 1998 included in the accounts
receivable balance is unbilled due to customer payment terms.

  The accompanying unaudited consolidated statements of the Company for the
three and six months ended June 30, 1999 and June 30, 1998, included herein,
have been prepared by the Company, without audit, pursuant to the rules and
regulations of the SEC. In the opinion of management, the accompanying unaudited
interim financial statements reflect all adjustments, consisting only of normal
recurring adjustments, necessary to present fairly the results of the Company's
operations and its cash flows for the three and six months ended June 30, 1999
and June 30, 1998. Certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules and
regulations relating to interim financial statements. These consolidated
financial statements should be read in conjunction with financial statements and
notes thereto included in the Company's 1998 Annual Report on Form 10-K.

Computation of Historical Net Loss Per Share and Pro Forma Net Loss Per Share

  Basic net loss per share is computed using the weighted average number of
common shares outstanding during the period. Dilutive net loss per share is
computed using the weighted average number of common and dilutive common
equivalent shares outstanding during the period. Common equivalent shares
consist of the incremental common shares issuable upon the exercise of stock
options and warrants (using the treasury stock method) and the incremental
common shares issuable upon the conversion of the convertible preferred stock
(using the if-converted method). Common equivalent shares are excluded from the
calculation if their effect is anti-dilutive. Pursuant to SEC Staff Accounting
Bulletin No. 98, common stock and convertible preferred stock issued for nominal
consideration, prior to the anticipated effective date of an IPO, are required
to be included in the calculation of basic and diluted net loss per share as if
they were outstanding for all periods presented. To date, the Company has not
had any issuances or grants for nominal consideration.

                                       7
<PAGE>

  Pro forma net loss per share is computed using the weighted average number of
shares of common stock outstanding, including common equivalent shares from the
convertible preferred stock (using the if-converted method), which automatically
converted into common stock upon the completion of the IPO as if converted at
the original date of issuance, for both basic and diluted net loss per share,
even though inclusion is antidilutive.

  The following table sets forth the reconciliation between the weighted average
shares outstanding for basic and diluted and pro forma net loss per share
computations:

(2)  INVESTMENTS

  The Company principally invests its excess cash in debt instruments of the
United States Government and its agencies, and in high-quality corporate
issuers.  All highly liquid instruments with an original maturity of three
months or less are considered cash equivalents, those with original maturities
greater than three months and current maturities less than twelve months from
the balance sheet date are considered short-term investments, and those with
maturities greater than twelve months from the balance sheet date are considered
long-term investments.

  The Company accounts for investments in accordance with SFAS No. 115,
"Accounting for Certain Investments in Debt and Equity Securities."  The
Company's marketable investments are classified as available-for-sale as of the
balance sheet date and are reported at fair value, with unrealized gains and
losses, net of tax, recorded in shareholders' equity.  Realized gains or losses
and permanent declines in value, if any, on available-for-sale securities will
be reported in other income or expense, as incurred.


(3)  COMMITMENTS AND CONTINGENCIES

  On June 30, 1998, the Company entered into a three year Sponsorship Agreement
with Excite, Inc. ("Excite"). The Sponsorship Agreement provides for the Company
and Excite to sponsor and promote 30 co-branded Web pages and for each company
to sell advertising on the Web pages. Excite has guaranteed a minimum number of
advertising impressions for each of the three years. The agreement is terminable
by either party, as defined, and requires the Company to pay Excite $0.9
million, $2.0 million and $3.0 million, respectively, in years one, two and
three under the agreement. Such payments will be charged to expense as the
advertising impressions are provided by Excite. In addition, each company will
provide the other with $200,000 in barter advertising during the term of the
Sponsorship Agreement. As of December 31, 1998, each company has satisfied the
barter provisions under the Sponsorship Agreement.  In June 1999, the agreement
with Excite was terminated.  The Company's remaining commitment to Excite is
$150,000 as of June 30, 1999.

  On January 19, 1999, the Company entered into a one-year agreement with Compaq
Computer Corporation ("Compaq") and its Internet Web site known as AltaVista.
The agreement provides for the Company and AltaVista to sponsor and promote 31

                                       8
<PAGE>

co-branded Web pages. The agreement requires the Company to pay Compaq $1.0
million over the term of the agreement based on the number of advertising
impressions delivered. Such amount will be charged to expense as AltaVista
provides the advertising impressions.  As of June 30,1999, no payments have been
made by the Company. In addition, each company will provide the other with
$300,000 in barter advertising during the term of the agreement.  The Company
has satisfied its barter advertising obligation under this agreement.

  The Company has entered into non-cancelable obligations with several content
service providers and Internet search engines. Under these agreements, exclusive
of the AltaVista agreement discussed above, the Company's commitments are as
follows:

</TABLE>


  On April 21, 1999, the Company entered into a 10 year lease for its
headquarters.  The total obligation under the lease is $9.0 million and is
payable in monthly payments of $75,222 commencing in July 1999.  According to
the terms of the lease agreement, the Company is required to maintain
certificates of deposit for an agreed upon amount in an escrow account.  The
certificates of deposit with an aggregate balance of $1,220,261 were issued in
June 1999 and will mature in five equal installments of $244,052 on August 1,
2000 and the four subsequent years thereafter.  The certificates of deposit are
classified as a long-term asset included in restricted cash on the balance
sheet.

  The Company is a party to legal proceedings and claims, which arise in the
ordinary course of business.  In the opinion of management, the amount of any
ultimate liability with respect to these actions will not materially affect the
financial position, results of operations or cash flows of the Company.


(4)  ACQUISITIONS

  In September 1998, the Company acquired all of the outstanding capital stock
of Boulder Interactive Technology Services Company ("BITC") for $1.8 million in
cash. BITC operates a vertical trade community for professionals in the radio
frequency and wireless communications industry. The acquisition was accounted
for using the purchase method of accounting. The excess of the purchase price
over the fair value of the net assets acquired of approximately $1,864,000 was
recorded as goodwill and is being amortized over 36 months.

  In September 1998, the Company acquired all of the outstanding capital stock
of Informatrix Worldwide, Inc. ("Informatrix") for 46,154 shares of the
Company's common stock valued at $153,000. Informatrix operates a vertical

acquired of approximately $903,000 was recorded as goodwill and is being
amortized over 36 months. The purchase agreement also provided for the Company
to issue up to 11,538 additional shares of the Company's common stock to the
Informatrix shareholders in the event that Informatrix achieved certain sales
targets through December 1998. Through October 31, 1998, the former shareholders
of Informatrix earned, and the Company recorded the issuance of, 2,200 shares of
common stock which was valued at $7,294. Through December 1998, the former
shareholders of Informatrix earned an additional 1,538 shares of common stock
which was valued at $24,608 and recorded by the Company in March 1999.  The
additional consideration was accounted for as additional goodwill.

  In January 1999, the Company acquired certain assets and assumed certain
liabilities including the Safetyonline Web site from Coastal Video
Communications ("Coastal").  The Company paid $260,000 in cash, issued a $50,000

Coastal an advertising commitment on the Company's Web site valued at $160,000.
As of June 30, 1999, the Company has paid the note to Coastal and has fulfilled
approximately $33,000 of its advertising commitment to Coastal.  The acquisition
was accounted for as a purchase and the estimated excess of the purchase price
over the fair value of the net assets acquired of approximately $550,000 was
recorded as goodwill and is being amortized over three years.  The results of
operations from Safetyonline are not material to the Company's consolidated
financial position or results of operations.

Web site, and assumed certain liabilities of a sole proprietor.  The Company
paid $975,000 in cash and issued 10,563 shares of its common stock valued at
$825,000. The acquisition was accounted for as a purchase and the estimated
excess of the purchase price over the fair value of the net assets acquired of
approximately $1.9 million was recorded as goodwill and is being amortized over
36 months.  The results of operations from ElectricNet are not material to the
Company's consolidated financial position or results of operations.

  On June 14, 1999, the Company acquired all of the outstanding capital stock of
Techspex, Inc. ("Techspex") for $211,000 in cash and 44,997 shares of  common
stock valued at $3.0 million. Techspex was the owner and operator of a vertical
trade community in the machine tools industry.  The Web site acts as a
comprehensive source of information, interaction and electronic commerce for the
machine tool industry providing a searchable database of machine tools, dealers
and tooling and accessory suppliers.  The acquisition was accounted for as a
purchase and the estimated excess of the purchase price over the fair value of
the net assets acquired of approximately $3.4 million was recorded as goodwill
and is being amortized over 36 months.

  The following unaudited pro forma financial information presents the combined
results of operations of VerticalNet, BITC, Informatrix and Techspex as if the
acquisitions occurred on January 1, 1998, after giving effect to certain
adjustments including amortization of goodwill. The unaudited pro forma
financial information does not necessarily reflect the results of operations
that would have occurred had VerticalNet, BITC, Informatrix and Techspex
constituted a single entity during such periods.

(6)  SUBSEQUENT EVENTS

  On July 29, 1999, the Company acquired all of the outstanding capital stock of
LabX  Technologies Inc. ("LabX") for $1.6 million in cash and 34,897 shares of
common stock valued at $ 3.2 million. LabX was the owner and operator of a
vertical trade community focused on electronic commerce of scientific and
laboratory equipment.  The Web site allows participants to communicate their
buying and selling requirements for laboratory equipment.  The acquisition was
accounted for as a purchase and the estimated excess of the purchase price over
the fair value of the net assets acquired of approximately $5.0 million will be
recorded as goodwill and be amortized over 36 months.

  On July 16, 1999, the Company acquired 414,233 shares of Tradex Inc.'s
("Tradex") Series C Preferred  Stock  at a cost  of $1.0 million.  The Company
currently owns 1.8% of Tradex and the investment will be accounted for under the
cost method of accounting.

  On July 16, 1999, the Company entered into a 3 year lease financing arragement
for office furniture.  The total obligation under the capital lease is $1.0
million and is payable in monthly payments of approximately $31,000, commencing
in July 1999.

  On July 21, 1999, the Board of Directors of the Company approved a two-for-one
stock split of the Company's common stock to be distributed in the form of a
stock dividend, payable on August 20, 1999, to shareholders of record at the
close of business on August 9, 1999.



ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

                           FORWARD LOOKING STATEMENTS

  Certain statements contained herein constitute "forward-looking statements"
within the meaning of the Private Securities Litigation Reform Act of 1995.
These forward-looking statements can be identified by the use of predictive,
future-tense or forward-looking terminology, such as "believes," "anticipates,"
"expects," "estimates," "plans," "may," "intends," "will," and words of similar
import. You are cautioned that any such forward-looking statements are not
guarantees of future performance and involve significant risks and
uncertainties.  You should not place undue reliance on these forward-looking
statements.  Actual results may differ materially from those projected in the
forward-looking statements for many reasons, including the various risks that
the Company faces as described below, elsewhere in this document and in other
documents that the Company files with the SEC.

  The following discussion of the financial condition and results of operations
of the Company should also be read in conjunction with the financial statements
and notes related thereto included elsewhere in this report.

                                    OVERVIEW

  We currently own and operate 43 vertical trade communities on the Internet.
Advertising revenues and Web site development fees contributed most of the
revenues for the three months ended June 30, 1999 and June 30, 1998.

  We sell storefront and banner advertising and event sponsorships on our
vertical trade communities. The duration of a storefront advertisement is
typically for a period of one year, while banner advertisements are typically
for a period of three months. All advertising revenues are recognized ratably
over the period in which the advertisement is displayed, provided that the
collection is reasonably assured. As of June 30, 1999, we had approximately $5.8
million of deferred revenue. We also generate revenues from career services,
auctions, education and electronic commerce, specifically the sale of books and
third party software.

  We offer for sale to our visitors:  books, software and other goods offered by
third party Web sites. Additionally, we offer auction sites with goods posted by
inventory-liquidators.  We receive a portion of the revenue from the products
sold on our "store" and our auction sites. This type of revenue sharing or
commission sharing relationship is typical of electronic commerce transactions
and relationships on the Internet. We receive either a fee per transaction, a
percentage of sales revenue or some other minimum guaranteed payment.

We plan to expand our electronic commerce relationships to include:

                                       11
<PAGE>

*  selling goods and services promoted on our advertisers' storefronts; and

*  selling goods and services from our owned and operated virtual store.

  We incurred net losses of approximately $6.8 million for the three months
ended June 30, 1999, $12.4 million for the six months ended June 30, 1999, $13.6
million for the year ended December 31, 1998, $4.8 million for the year ended
December 31, 1997 and $709,000 for the year ended December 31, 1996.  At June
30, 1999 we had an accumulated deficit of $31.7 million. The net losses and
accumulated deficit resulted from our lack of substantial revenues, the costs of
the significant infrastructure and other costs incurred for the development and
initial rollout of our vertical trade communities. Because of our aggressive
expansion plans, we expect to incur significant operating losses for the
foreseeable future. Although we have experienced revenue growth in recent
periods, such growth may not be sustainable and, therefore, these recent periods
should not be considered indicative of future performance. We may never achieve
significant revenues or profitability, or if we achieve significant revenues, it
may not be sustained.

                             RESULTS OF OPERATIONS

SIX MONTHS ENDED JUNE 30, 1999 AND JUNE 30, 1998

  Revenues.  Revenues increased from $965,000 for the six months ended June 30,
1998 to $5.5 million for the six months ended June 30, 1999.  The increase in
revenues was due primarily to an increase in (i) the number of storefronts from
833 as of June 30, 1998 to 2,094 as of June 30, 1999 (ii) the number of vertical
trade communities from 17 as of June 30, 1998 to 43 as of June 30, 1999.
Advertising revenues, including the development of the storefronts, accounted
for the majority of revenues for the periods ended June 30, 1998 and June 30,
1999.  Barter transactions, in which the Company received advertising or other
services in exchange for advertising on its Web sites accounted for
approximately 24% of total revenues for the six months ended June 30, 1999 and
none for the six months ended June 30, 1998.  At June 30, 1999, we had deferred
revenues of $5.8 million.  We expect that advertising revenue will continue to
account for a substantial share of revenues for the foreseeable future.

  Editorial and Operational Expenses.  Editorial and operational expenses
consist primarily of Internet connection charges, cost of acquired content,
depreciation, salaries and benefits of operating and editorial personnel and
other related operating costs.  These expenses increased from $1.1 million for
the six months ended June 30, 1998 to $2.9 million for the six months ended June
30, 1999.  For these periods, expenses increased by $1.5 million for salaries
and benefits of operating and editorial personnel and $300,000 for depreciation,
Internet connection charges, acquired content, product costs and other related
operating costs.  The increases were primarily related to the increased number
of personnel and amount of equipment required to maintain and operate our
increased number of vertical trade communities.

  Product Development Expenses.  Product development expenses consist primarily
of salaries and benefits, consulting expenses and related equipment.  These
costs increased from $578,000 for the six months ended June 30, 1998 to $2.7
million for the six months ended June 30, 1999.  For these periods, expenses
increased by $1.4 million for salaries and benefit costs and by $722,000 for
consulting and equipment costs.  This increase in expenses was due to increased
staffing and the costs of enhancing the features, content and services of our
vertical trade communities, as well as increasing the overall number of vertical
trade communities.  To date, we have charged to expense all the product
development costs when such costs have been incurred.  We believe that continued
investment in product development is critical to attaining our goals, and
therefore expect product development expenses to increase significantly.

  Sales and Marketing Expenses.  Sales and marketing expenses consist primarily
of salaries and commissions for sales and marketing personnel, advertising and
travel and entertainment, including costs of attending trade shows.  These
expenses increased from $2.6 million for the six months ended June 30, 1998 to
$9.2 million for the six months ended June 30, 1999.  For these periods,
expenses increased by $2.4 million for advertising, $3.0 million for salaries,
commissions and benefits, and $1.2 million for travel and entertainment
expenses, including costs of attending trade shows.  This was primarily due to
increasing the number of sales and marketing personnel, increasing sales
commissions and increased expenses related to promoting our vertical trade
communities.  We expect these expenses will continue to grow significantly, as
we pursue an aggressive growth strategy and hire additional sales/marketing
personnel.

  General and Administrative Expenses.  General and administrative expenses
consist primarily of salaries and related costs for our executive,
administrative, finance, human resources and business development personnel, as
well as support services and

                                       12
<PAGE>

professional service fees. These expenses increased from $1.5 million for the
six months ended June 30, 1998 to $4.0 million (including goodwill amortization
of $610,000) for the six months ended June 30, 1999. For these periods, expenses
increased by $340,000 for general and administrative personnel, $644,000 for
depreciation and goodwill amortization, $379,000 for professional fees, $600,000
for facility costs and $537,000 for other general and administrative costs. The
increase was due primarily to increases in the number of personnel to support
and grow our business. We expect these expenses to grow as additional personnel
are hired and additional expenses are incurred. These expenses relate to growing
our business and operating as a public company.

  Interest, Net.  Interest income, net of expense of $176,000, includes income
from cash and cash equivalents and from investments and expenses related to our
financing obligations.  Interest income net of interest expense increased from
an expense of $62,000 for the six months ended June 30, 1998 to income of
$862,000 for the six months ended June 30, 1999.  The increase was primarily due
to a higher investment balance as a result of the initial public offering.
Currently, we invest the majority of our cash balances in debt instruments of
the United States Government and its agencies, and in high-quality corporate
issuers.


THREE MONTHS ENDED JUNE 30, 1999 AND JUNE 30, 1998

  Revenues.  Revenues increased from $587,000 for the three months ended June
30, 1998 to $3.6 million for the three months ended June 30, 1999.  The increase
in revenues was due primarily to an increase in (i) the number of storefronts
from 833 as of June 30, 1998 to 2,094 as of June 30, 1999 (ii) the number of
vertical trade communities from 17 as of June 30, 1998 to 43 as of June 30,
1999.  Advertising revenues, including the development of the storefronts,
accounted for the majority of revenues for the periods ended June 30, 1998 and
June 30, 1999.  Barter transactions, in which the Company received advertising
or other services in exchange for advertising on its Web sites accounted for
approximately 21% of total revenues for the three months ended June 30, 1999 and
none for the three months ended June 30, 1998.  At June 30, 1999, we had
deferred revenues of $5.8 million.  We expect that advertising revenue will
continue to account for a substantial share of revenues for the foreseeable
future.

  Editorial and Operational Expenses.  These expenses increased from $690,000
for the three months ended June 30, 1998 to $1.7 million for the three months
ended June 30, 1999.  For these periods, expenses increased by $881,000 for
salaries and benefits of operating and editorial personnel and $129,000 for
depreciation, Internet connection charges, acquired content, product costs and
other related operating costs.  The increases were primarily related to the
increased number of personnel and amount of equipment required to maintain and
operate our increased number of vertical trade communities.

  Product Development Expenses  These costs increased from $385,000 for the
three months ended June 30, 1998 to $1.5 million for the three months ended June
30, 1999.  For these periods, expenses increased by $803,000 for salaries and
benefit costs and by $312,000 for consulting and equipment costs.  This increase
in expenses was due to increased staffing and the costs of enhancing the
features, content and services of our vertical trade communities, as well as
increasing the overall number of vertical trade communities.  To date, we have
charged to expense all the product development costs when such costs have been
incurred.  We believe that continued investment in product development is
critical to attaining our goals, and therefore expect product development
expenses to increase significantly.

  Sales and Marketing Expenses.  These expenses increased from $1.7 million for
the three months ended June 30, 1998 to $5.5 million for the three months ended
June 30, 1999.  For these periods, expenses increased by $1.4 million for
advertising, $1.9 million for salaries, commissions and benefits, and $500,000
for travel and entertainment expenses, including costs of attending trade shows.
This was primarily due to increasing the number of sales and marketing
personnel, increasing sales commissions and increased expenses related to
promoting our vertical trade communities.  We expect these expenses will
continue to grow significantly, as we pursue an aggressive growth strategy and
hire additional sales/marketing personnel.

General and Administrative Expenses.  These expenses increased from $719,000 for
the three months ended June 30, 1998 to $2.3 million (including goodwill
amortization of $336,000) for the three months ended June 30, 1999.  For these
periods, expenses increased by $132,000 for general and administrative
personnel, $359,000 for depreciation and goodwill amortization, $314,000 for
professional fees, $323,000 for facility costs and $453,000 for other general
and administrative costs.  The increase was primarily due to increases in the
number of personnel to support and grow our business.  We expect these expenses
to grow as additional personnel are hired and additional expenses are incurred.
These expenses relate to growing our business and operating as a public company.

  Interest, Net.  Interest income, net of expense of $7,000, includes income
from cash and cash equivalents and from investments and expenses related to our
financing obligations.  Interest income net of interest expense increased from
$14,000 for the three months ended June 30, 1998 to $715,000 for the three
months ended June 30, 1999.  The increase was primarily due to a higher
investment balance as a result of the initial public offering.  Currently, we
invest the majority of our cash balances in debt instruments of the United
States Government and its agencies, and in high-quality corporate issuers.


LIQUIDITY AND CAPITAL RESOURCES

   As of June 30, 1999, the Company's primary source of liquidity consisted of
cash and highly liquid, high-quality debt instruments. The Company's intent is
to make such funds, of which the majority have maturities of less than one year,
readily available for operating purposes. On February 17, 1999, the Company
completed its initial public offering of 4,025,000 shares of common stock,
resulting in the net proceeds of $58.3 million. At June 30, 1999, the Company
had cash and cash equivalents and investments in marketable debt securities
totaling $47.1 million compared to $5.7 million at December 31, 1998.

   We had a line of credit with a commercial bank for $500,000, which expired on
June 30, 1999.  The line of credit was not subsequently renewed.

   We have several capital leases with various financial institutions for
computer and communications equipment used in our operations with lease terms
ranging from three to five years.  Additionally, we have an insurance premium
financing agreement for our directors and officers liability insurance.  The
interest rates under the leases and insurance premium financing agreement range
from 8% to 20% and we are required to make total monthly payments of
approximately $69,000 under the terms of these agreements.

   For the six months ended June 30, 1999, cash used in operating activities was
$10.6 million.  Cash used in operating activities consisted mostly of net
operating losses and increases in accounts receivable and prepaid expenses,
partially offset by increases in deferred revenues, accrued expenses and
accounts payable.

   Net cash used in investing activities was $31.2 million for the six months
ended June 30, 1999.  Our investing activities included the purchases of
marketable securities for $27.1 million (net of sales maturities), capital
expenditures for $631,000, the acquisitions of Safetyonline, Techspex, Oillink
and ElectricNet for $1.9 million and a bridge loan to Isadra for $390,000.

   For the six months ended June 30, 1999, cash provided by financing activities
of $56.3 million was primarily due to our initial public offering which raised
net proceeds of $58.5 million and the exercise of stock options.  These amounts
were partially offset by the repayment of the $2.0 million line of credit that
was outstanding as of December 31, 1998 and principal payments on capital lease
obligations.

  On May 24, 1999, the Company and Isadra, Inc. ("Isadra") signed an agreement
and Plan of Merger to acquire all of the outstanding capital stock of Isadra for
$3.0 million cash and 500,000 shares of common stock. The closing of this
transaction is subject to regulatory and shareholder approval by Isadra's
shareholders. Isadra has developed e-commerce software for vertical industries.
In connection with this transaction, the Company has agreed to lend up to $1.0
million prior to closing of this transaction. As of June 30, 1999, the Company
has advanced Isadra $390,000. In the event that this transaction does not close,
Isadra is obligated to repay the $1.0 million loan by October 31, 1999. The
acquisition will be accounted for using the purchase method of accounting. The
estimated excess of the purchase price over the fair value of the net assets
acquired of approximately $42.1 million is expected to be allocated among
existing technology, in-process research and development and goodwill, then
amortized over their respective lives.

  On July 29, 1999, the Company acquired all of the outstanding capital stock of
LabX Technologies Inc. ("LabX") for $1.6 million in cash and 34,897 shares of
common stock valued at $3.2 million. LabX was the owner and operator of a
vertical trade community focused on electronic commerce of scientific and
labatory equipment. The Web site allows participants to communicate their buying
and selling requirements for labortory equipment. The acquisition was accounted
for as a purchase and the estimated excess of the purchase price over the fair
value of the net assets acquired of approximately $5.0 million will be recorded
as goodwill and be amortized over 36 months.

YEAR 2000 COMPLIANCE

We may realize exposure and risk if the systems on which we are dependent to
conduct our operations are not Year 2000 compliant. Our potential areas of
exposure include products purchased from third parties, information technology
including computers and software, and non-information technology including
telephone systems and other equipment used internally.

The internally developed production and operation systems for our Web sites have
recently undergone a complete re-engineering. All new programs have been
substantially tested and validated for Year 2000 compliance.

Our communications infrastructure was recently overhauled, including a full
conversion of our telephone and voicemail systems. We believe all non-
information technology equipment upon which we are materially dependent is Year
2000 compliant. Additionally, with respect to information technology, we have
resolved all Year 2000 compliance issues primarily through normal upgrades of
our software or replacements included in our capital expenditure budget and
these costs are not expected to be material to our financial position or results
of operations. Our original Year 2000 compliance cost estimate did not exceed
$250,000 and remains valid. However, such upgrades and replacements may not
successfully address our Year 2000 compliance issues as represented by our
distributors, vendors and suppliers.

We have completed our Year 2000 compliance assessment plan. This plan includes
assessing both our information and non-information technology as well as our
internally developed production and operation systems. Based on this assessment,
we believe that all non-information technology, all internally developed
production and operations systems and 95% of our technology are Year 2000
compliant. We believe that the remaining 5% of our information technology that
is not Year 2000 compliant will be addressed with the completion of our Unix
conversion in August 1999.

In addition, we have obtained verification from our key distributors, vendors
and suppliers that they are Year 2000 compliant or, if they are not fully
compliant, to provide a description of their plans to become so. We have
received certification from 100% of our distributors, vendors and suppliers that
they are complete or are in accordance with their scheduled Year 2000 compliance
plan. We will continue to monitor the status of all of our key vendors with the
intent of terminating and replacing those relationships which may jeopardize our
own Year 2000 compliance plan.

In the event that our production and operational facilities that support our Web
sites are disrupted, small portions of our Web sites may become unavailable. Our
review of our systems has shown that there is no single application that would
make our Web sites totally unavailable and we believe that we can quickly
address any difficulties that may arise.

Having completed a specific analysis of our Web-hosting facilities, all
functionalities are in compliance with our Year 2000 compliance assessment plan.
In the event that our Web-hosting facilities are not Year 2000 compliant, our
Web sites would be unavailable and we would not be able to deliver services to
our users.

We have developed a comprehensive list of contingency models to forecast the
worst-case scenario that might occur if technologies we are dependent upon are
not Year 2000 compliant and fail to operate effectively after the Year 2000. All
identified scenarios have been determined to be resolvable by an on-site staff
which will be maintained throughout the Year 2000 date changeover with the
exception of the Exodus hosting functionalities. Exodus has remitted Year 2000
certification and we are in the process of reviewing potential back-up sites
within our disaster recovery planning.

If our present efforts to address the Year 2000 compliance issues are not
successful, or if distributors, suppliers and other third parties with which we
conduct business do not successfully address such issues, our business,
operating results and financial position could be materially and adversely
affected.


FACTORS AFFECTING OUR BUSINESS CONDITION

  In addition to the other information included in this Report, the following
factors should be considered in evaluating our business and future prospects:

                                       15
<PAGE>

WE HAVE LIMITED OPERATING HISTORY UPON WHICH YOU MAY EVALUATE US

  We launched our first vertical trade community in October 1995. Accordingly,
we have a limited operating history upon which you may evaluate us. In addition,
our revenue model is evolving. Currently, our revenues are primarily generated
from the sale of advertising on our vertical trade communities. In the future,
we expect to generate revenue from multiple sources, including electronic
commerce and business services. We may not be able to sustain our current
revenues or successfully generate electronic commerce or business services
revenue. If we do not generate such revenue, our business, financial condition
and operating results will be materially adversely affected.

WE ANTICIPATE WE WILL INCUR CONTINUED LOSSES FOR THE FORESEEABLE FUTURE

  To date, we have not been profitable. We may never be profitable or, if we
become profitable, we may be unable to sustain profitability. We have incurred
significant losses since inception. We reported a net loss of $12.4 million for
the six months ended June 30, 1999.  We expect to continue to incur significant
losses for the foreseeable future. As of June 30, 1999, our accumulated deficit
was $31.7 million. Our limited operating history makes predicting our future
operating results, including operating expenses, difficult. Our revenues may not
grow or may not even continue at their current level.

WE EXPECT OUR OPERATING EXPENSES TO INCREASE

  Some of our expenses are fixed, including non-cancelable agreements, equipment
leases and real estate leases. If our revenues do not increase, we may not be
able to compensate by reducing expenses in a timely manner. In addition, we plan
to significantly increase our operating expenses to:

*  launch additional vertical trade communities;

*  increase our sales and marketing operations;

*  enter into additional sponsorship agreements;

*  broaden our customer support capabilities; and

*  pursue marketing and distribution alliances.

  Expenses will also increase due to the potential impact of goodwill and other
charges resulting from completed and future acquisitions.

  Additionally, leading Web sites, browser providers and other Internet
distribution channels may begin to charge us to provide access to our products
and services. If any of these expenses are not accompanied by increased
revenues, our business, financial condition and operating results would be
materially adversely affected.

FLUCTUATIONS IN OUR QUARTERLY RESULTS MAY ADVERSELY AFFECT OUR STOCK PRICE

  We expect that our quarterly operating results will fluctuate significantly
due to many factors, including:

*  the seasonality of our revenues;

*  the uncertain adoption of the Internet as an advertising medium;

*  potential dependence on development of the electronic commerce market;

*  intense competition;

*  our dependence on content providers;

*  license fees payable to content providers;

*  uncertain acceptance of our Internet content;

*  management of our growth; and

                                       16
<PAGE>

*  risks associated with potential acquisitions.

  Many of these factors are beyond our control.

  Due to the limited history of businesses relying on the Internet as a
commercial medium, we believe that period-to-period comparisons of our operating
results are not meaningful. Additionally, if our operating results in one or
more quarters do not meet the securities analysts' or our shareholders'
expectations, the price of our common stock could be materially adversely
affected.

MARKETING AND DISTRIBUTION ALLIANCES MAY NOT GENERATE THE EXPECTED NUMBER OF NEW
CUSTOMERS OR MAY BE TERMINATED

  We use marketing and distribution alliances with other Internet companies to
create traffic on our vertical trade communities and consequently, to generate
revenues. These marketing and distribution alliances allow us to link our
vertical trade communities to search engines such as those offered by Excite,
and on other Web sites such as AltaVista. The success of these relationships
depends on the amount of increased traffic we receive from the alliance
partners' Web sites. These arrangements may not generate the expected number of
new customers. We also cannot be assured that we will be able to renew these
marketing and distribution alliance agreements. If any of these agreements are
terminated, the traffic on our vertical trade communities could decrease or our
advertising revenues derived from the sales of advertising on co-branded pages
could decrease.  In June 1999, a three year Sponsorship Agreement with Excite,
Inc. ("Excite") entered into on June 30, 1998 was terminated.  The Company's
remaining commitment to Excite is $150,000 as of June 30, 1999.


ACQUISITIONS MAY DISRUPT OR OTHERWISE HAVE A NEGATIVE IMPACT ON OUR BUSINESS

  We have made, and plan to continue to make, investments in complementary
companies, technologies and assets. Future acquisitions are subject to the
following risks:

*  acquisitions may cause a disruption in our ongoing business, distract our
management and other resources and make it difficult to maintain our standards,
controls and procedures;

*  we may acquire companies in markets in which we have little experience;

*  we may not be able to successfully integrate the services, products and
personnel of any acquisition into our operations;

*  we may be required to incur debt or issue equity securities, which may be
dilutive to existing shareholders, to pay for acquisitions; and

*  our acquisitions may not result in any return on our investment and we may
lose our entire investment.

THE SEASONALITY OF OUR ADVERTISING REVENUES AND USAGE CAUSES OUR OVERALL
REVENUES TO BE SEASONAL

  Some of our revenue is seasonal, which causes our revenues to be lower in the
second and third quarters of each calendar year. As a result, after the
announcement of our results for the second and third quarters or each calendar
year, our stock price may be lower than at other times of the year. We
experience seasonality in our advertising revenue because advertising and media
buying tends to be highest in the first and fourth quarters of each calendar
year. We also experience seasonality in our traffic. User traffic on our
vertical trade communities and the Web sites of our partners is lower during the
summer and year-end vacation and holiday periods, when business usage of the Web
and our services typically declines.

WE CURRENTLY RELY HEAVILY ON ADVERTISING REVENUES AND IF OUR ADVERTISING
REVENUES DECLINE OUR BUSINESS WOULD BE ADVERSELY AFFECTED

  We currently rely on revenues generated from the sale of advertising on our
vertical trade communities for substantially all of our revenues. If we do not
continue to develop advertising and other sources of revenues, our business may
be materially adversely affected. Our ability to increase our advertising
revenues may depend, among other things, on many factors, including:

*  advertisers' acceptance of the Internet as a legitimate advertising medium;

                                       17
<PAGE>

*  the development of a large base of users on our vertical trade communities
who possess demographic characteristics attractive to advertisers; and

*  the expansion of our sales force.

  Additionally, for certain advertising customers the Company provides extended
payment terms over the customer's advertising contract.  To the extent that
these amounts are not collected, the Company's advertising revenues, bad debt
expense and cash flows could be adversely affected.

  Other factors could also affect our revenues. For example, widespread use of
"filter" software programs that limit access to storefront advertising from the
Internet user's browser could reduce advertising on the Internet, which would
materially adversely affect our business, financial condition and operating
results.

CHANGES IN INDUSTRY ADVERTISING RATES COULD ADVERSELY AFFECT OUR REVENUES

  Changes in industry pricing practices for advertising rates could materially
adversely affect our revenues in the future. Currently, we base our storefront
advertising rates on a variety of factors including the maturity of the
particular vertical trade community, the number of storefronts, the amount of
other advertising purchased and the length of the advertising contract. In the
future, advertising rates may be based on different parameters such as the
number of sales inquiries generated or visitors sent from our vertical trade
communities to advertisers' Web sites. These changes could materially adversely
affect our revenues.

ADOPTION OF THE INTERNET AS AN ADVERTISING MEDIUM IS UNCERTAIN

  The growth of Internet advertising requires validation of the Internet as an
effective advertising medium. This validation has yet to fully occur. Acceptance
of the Internet among advertisers will also depend on growth in the commercial
use of the Internet. If widespread commercial use of the Internet does not
develop, or if the Internet does not develop as an effective and measurable
medium for advertising, our business, financial condition and operating results
could be materially adversely affected.

  No standards have been widely accepted to measure the effectiveness of
Internet advertising. If such standards do not develop, existing advertisers may
not continue their current levels of Internet advertising and advertisers who
are not currently advertising on the Internet may be reluctant to do so. Our
business, financial condition and operating results would be adversely affected
if the market for Internet advertising fails to develop or develops slower than
expected.

WE MAY NOT DEVELOP SIGNIFICANT REVENUES FROM ELECTRONIC COMMERCE, WHICH COULD
ADVERSELY AFFECT OUR FUTURE GROWTH

  For the three months ended June 30, 1999, approximately 5% of our revenues
were generated from electronic commerce. If we do not generate increased revenue
from electronic commerce, our business, financial condition and operating
results could be materially adversely affected. To generate significant
electronic commerce revenues, we will have to continue to build or license an
electronic commerce platform.

OUR LONG-TERM SUCCESS DEPENDS ON THE DEVELOPMENT OF THE ELECTRONIC COMMERCE
MARKET, WHICH IS UNCERTAIN

  If electronic commerce does not grow or grows slower than expected, our
business will suffer. Our long-term success depends on widespread market-
acceptance of electronic commerce.

  A number of factors could prevent such acceptance, including the following:

*  electronic commerce is at an early stage and buyers may be unwilling to shift
their purchasing from traditional vendors to online vendors;

*  the necessary network infrastructure for substantial growth in usage of the
Internet may not be adequately developed;

*  increased government regulation or taxation may adversely affect the
viability of electronic commerce;

*  insufficient availability of telecommunication services or changes in
telecommunication services could result in slower response times; and

                                       18
<PAGE>

*  adverse publicity and consumer concern about the security of electronic
commerce transactions could discourage its acceptance and growth.

THERE IS INTENSE COMPETITION FOR THE INTERNET PRODUCTS AND SERVICES, ADVERTISING
AND SALES OF GOODS AND SERVICES THAT WE OFFER

  Competition for Internet products and services, advertising and electronic
commerce is intense. We expect that competition will continue to intensify.
Barriers to entry are minimal, and competitors can launch new Web sites at a
relatively low cost. We compete for a share of a customer's advertising budget
with online services and traditional off-line media, such as print publications
and trade associations. Although to date we believe there are no companies with
a larger portfolio of vertical trade communities than ours, several companies
offer competitive vertical trade communities. We expect that additional
companies will offer competing vertical trade communities on a standalone or
portfolio basis.

  Our competitors may develop Internet products or services that are superior
to, or have greater market acceptance than, our solutions. If we are unable to
compete successfully against our competitors, our business, financial condition
and operating results will be adversely affected.

  Many of our competitors have greater brand recognition and greater financial,
marketing and other resources than ours. This may place us at a disadvantage in
responding to our competitors' pricing strategies, technological advances,
advertising campaigns, strategic partnerships and other initiatives.

CONCERNS REGARDING SECURITY OF TRANSACTIONS AND TRANSMITTING CONFIDENTIAL
INFORMATION OVER THE INTERNET MAY NEGATIVELY IMPACT OUR ELECTRONIC COMMERCE
BUSINESS

  We believe that concern regarding the security of confidential information
transmitted over the Internet, such as credit card numbers, prevents many
potential customers from engaging in online transactions. If we do not add
sufficient security features to future product releases, our products may not
gain market acceptance or we may incur additional legal exposure. We have
included basic security features in some of our products to protect the privacy
and integrity of customer data, such as password requirements for access to
portions of our vertical trade communities. We do not currently use
authentication technology, which requires passwords and other information to
prevent unauthorized persons from accessing a customer's information, or
encryption, which transforms information into a "code" designed to be unreadable
by third parties, to protect confidential information such as credit card
numbers. However, we intend to license encryption technology to protect
confidential transaction data.

  Despite the measures we have taken, our infrastructure is potentially
vulnerable to physical or electronic break-ins, viruses or similar problems. If
a person circumvents our security measures, he or she could misappropriate
proprietary information or cause interruptions in our operations. Security
breaches that result in access to confidential information could damage our
reputation and expose us to a risk of loss or liability. We may be required to
make significant investments and efforts to protect against or remedy security
breaches. Additionally, as electronic commerce becomes more prevalent (and
consequently becomes the focus of our development of direct marketing products),
our customers will become more concerned about security. If we do not adequately
address these concerns, this could materially adversely affect our business,
financial condition and operating results.

WE MAY NOT HAVE OPPORTUNITIES TO ENTER INTO NEW PARTNERSHIPS OR MARKETING AND
DISTRIBUTION ALLIANCES

  We are interested in entering into additional partnerships with search engine
providers to increase traffic to our vertical trade communities, but we cannot
be assured that we will be able to enter into any new partnerships. If we are
unable to enter into new arrangements the traffic on our vertical trade
communities may not increase.

OUR BUSINESS DEPENDS ON THE GROWTH OF THE INTERNET, WHICH IS UNCERTAIN

  Our market is new and rapidly evolving. Our business would be adversely
affected if Internet usage does not continue to grow. Internet usage may be
inhibited by a number of reasons, such as:

*  infrastructure;

*  security concerns;

                                       19
<PAGE>

*  inconsistent quality of service; and

*  lack of availability of cost-effective, high-speed service.

  If Internet usage grows, the Internet infrastructure may not be able to
support the demands placed on it by this growth or its performance or
reliability may decline. In addition, Web sites may from time to time experience
interruptions in their service as a result of outages and other delays occurring
throughout the Internet network infrastructure. If these outages or delays
frequently occur in the future, Internet usage, as well as usage of our vertical
trade communities, could be adversely affected.

OUR INTERNET CONTENT MAY NOT ATTRACT USERS WITH DEMOGRAPHIC CHARACTERISTICS
VALUABLE TO OUR ADVERTISERS

  Our future success depends upon our ability to deliver compelling Internet
content about various industries that will attract users with demographic
characteristics valuable to our advertising customers. If we are unable to
develop Internet content that attracts a loyal user base possessing demographic
characteristics attractive to advertisers, it could have a material adverse
effect on our business, financial condition and operating results. In addition,
we may be unable to anticipate or respond to rapidly changing buyer preferences
to attract enough users to our vertical trade communities. Internet users can
freely navigate and instantly switch among a large number of Web sites. Many of
these Internet sites offer original content. Thus, it is difficult for us to
distinguish our content and attract users.

WE MAY NOT BE ABLE TO MAINTAIN RELATIONSHIPS WITH THE THIRD PARTIES WE DEPEND
UPON TO PROVIDE THE CONTENT FOR OUR VERTICAL TRADE COMMUNITIES, WHICH COULD
RESULT IN DECREASED TRAFFIC ON THE VERTICAL TRADE COMMUNITIES AND DECREASED
ADVERTISING REVENUE

  We rely on third parties, such as trade publications and news wires, to
provide some of the content for our vertical trade communities. It is critical
to our business that we maintain and build our existing relationships with
content providers. Many of our agreements with content providers are for initial
terms of one to two years. The content providers may choose not to renew the
agreements or may terminate the agreements early if we do not fulfill our
contractual obligations, including our payment obligations. If a significant
number of content providers terminate our agreements with them, it could result
in decreased traffic on our vertical trade communities and decreased advertising
revenue. Because our agreements with certain of our content providers are
nonexclusive, a competitor could offer content similar to or the same as ours.

THE LICENSEE FEES WE PAY TO CONTENT PROVIDERS MAY INCREASE

  If licensing fees increase, it could materially adversely affect our business,
financial condition and operating results. License fees to content providers may
increase as competition for such content increases. Our content providers may
not enter into new agreements with us on similar terms as our current
agreements.

IF WE DO NOT DEVELOP THE "VERTICALNET" BRAND AND OUR VERTICAL TRADE COMMUNITY
BRANDS OUR ADVERTISING REVENUES COULD DECREASE

  To be successful, we must establish and strengthen the brand awareness of the
"VerticalNet" brand as well as the brands associated with each individual
vertical trade community (e.g. wateronline.com). If our brand awareness is
weakened, it could decrease the attractiveness of our audiences to advertisers,
which could result in decreasing advertising revenues. We believe that brand
recognition will become more important in the future with the growing number of
Internet sites. Our brand awareness could be diluted, which could adversely
affect our business, financial condition and operating results if users do not
perceive our products and services to be of high quality.

WE ARE GROWING RAPIDLY AND EFFECTIVELY MANAGING OUR GROWTH MAY BE DIFFICULT

  We have grown and expect to continue to grow rapidly both by adding new
products and hiring new employees. This growth is likely to place a significant
strain on our resources and systems. To manage our growth, we must implement
systems and train and manage our employees.

  Many of our senior management have only recently joined us. Of our seven
executive officers, two have worked for us less than one year. We cannot assure
you that our management will be able to effectively or successfully manage our
growth.

WE MAY NOT BE ABLE TO PROTECT OUR PROPRIETARY RIGHTS AND WE MAY INFRINGE THE
PROPRIETARY RIGHTS OF OTHERS

                                       20
<PAGE>

  Proprietary rights are important to our success and our competitive position.
We have applied for several trademarks, of which only one has been issued to
date. Although we seek to protect our proprietary rights, our actions may be
inadequate to protect any trademarks and other proprietary rights or to prevent
others from claiming violations of their trademarks and other proprietary
rights. We currently have two pending trademark applications. Generally, our
domain names for our vertical trade communities are not protectable as
trademarks because they are too generic. In addition, effective copyright and
trademark protection may be unenforceable or limited in certain countries, and
the global nature of the Internet makes it impossible to control the ultimate
destination of our work. We also license content from third parties and it is
possible that we could become subject to infringement actions based upon the
content licensed from those third parties. We generally obtain representations
as to the origin and ownership of such licensed content; however, this may not
adequately protect us. Any of these claims, with or without merit, could subject
us to costly litigation and the diversion of our technical and management
personnel.

WE MAY NOT BE ABLE TO ACQUIRE OR MAINTAIN EASILY IDENTIFIABLE WEB ADDRESSES OR
PREVENT THIRD PARTIES FROM ACQUIRING WEB ADDRESSES SIMILAR TO OURS

  We currently hold various Internet Web addresses relating to our brand. These
Web addresses include wateronline.com, wirelessdesignonline.com,
pollutiononline.com and other Web addresses. We may not be able to prevent third
parties from acquiring Web addresses that are similar to our addresses, which
could materially adversely affect our business, financial condition and
operating results. The acquisition and maintenance of Web addresses generally is
regulated by governmental agencies and their designees. For example, in the
United States, the National Science Foundation has appointed Network Solutions,
Inc. as the exclusive registrar for the ".com," ".net" and ".org" generic top-
level addresses. The regulation of Web addresses in the United States and in
foreign countries is subject to change.  We may not be able to acquire or
maintain relevant Web addresses in all countries where we conduct business.
Furthermore, the relationship between regulations governing such addresses and
laws protecting trademarks is unclear.

WE MAY NOT BE ABLE TO EFFECT OUR GROWTH STRATEGY IF WE ARE NOT ABLE TO
CONSUMMATE FUTURE ACQUISITIONS

  Our acquisition strategy is subject to the risk of not being able to identify
additional suitable acquisition candidates available for sale at reasonable
prices or on reasonable terms. Additionally, regardless of whether suitable
candidates are available, we may not be able to consummate future acquisitions
for other reasons such as the availability of capital. If we are unable to
consummate future acquisitions, our business, financial condition and operating
results could be adversely affected.

WE MAY BE SUBJECT TO LEGAL LIABILITY FOR PUBLISHING OR DISTRIBUTING CONTENT OVER
THE INTERNET

  We may be subject to legal claims relating to the content in our vertical
trade communities, or the downloading and distribution of such content. For
example, persons may bring claims against us if material that is inappropriate
for viewing by young children can be accessed from our vertical trade
communities. Claims could also involve matters such as defamation, invasion of
privacy, and copyright infringement. Providers of Internet products and services
have been sued in the past, sometimes successfully, based on the content of
material. In addition, some of the content provided on our vertical trade
communities is drawn from data compiled by other parties, including governmental
and commercial sources, and we re-key the data. This data may have errors. If
our content is improperly used or if we supply incorrect information, it could
result in unexpected liability. Our insurance may not cover claims of this type,
or may not provide sufficient coverage. Our business, financial condition and
operating results could suffer a material adverse effect if costs resulting from
these claims are not covered by our insurance or exceed our coverage.

RISK OF FAILURE OF OUR COMPUTER AND COMMUNICATIONS HARDWARE SYSTEMS INCREASES
WITHOUT BACK-UP FACILITIES

  Our business depends on the efficient and uninterrupted operation of our
computer and communications hardware systems. Any system interruptions that
cause our vertical trade communities to be unavailable to Web browsers may
reduce the attractiveness of our vertical trade communities to advertisers and
could materially adversely affect our business, financial condition and
operating results. We maintain most of our computer systems in two Web-hosting
facilities in New Jersey. However, we do not have back-up or redundant
facilities for our computer systems. Interruptions could result from natural
disasters as well as power loss, telecommunications failure and similar events.

CAPACITY LIMITS ON OUR TECHNOLOGY, TRANSACTION PROCESSING SYSTEM AND NETWORK
HARDWARE AND SOFTWARE MAY BE DIFFICULT TO PROJECT AND WE MAY NOT BE ABLE TO
EXPAND AND UPGRADE OUR SYSTEMS TO MEET INCREASED USE

  As traffic in our vertical trade communities continues to increase, we must
expand and upgrade our technology, transaction processing systems and network
hardware and software. We may not be able to accurately project the rate of
increase in our

                                       21
<PAGE>

vertical trade communities. In addition, we may not be able to expand and
upgrade our systems and network hardware and software capabilities to
accommodate increased use of our vertical trade communities. If we do not
appropriately upgrade our systems and network hardware and software, our
business, financial condition and operating results will be materially adversely
affected.

OUR MARKET IS CHARACTERIZED BY RAPID TECHNOLOGICAL CHANGE, WHICH WE MAY NOT BE
ABLE TO KEEP UP WITH IN A COST-EFFECTIVE WAY

  Our market is characterized by rapid technological change and frequent new
product announcements. Significant technological changes could render our
existing vertical trade community technology obsolete. If we are unable to
successfully respond to these developments or do not respond in a cost-effective
way, our business, financial condition and operating results will be materially
adversely affected. To be successful, we must adapt to our rapidly changing
market by continually improving the responsiveness, services and features of our
vertical trade communities and by developing new features to meet customer
needs.  Our success will depend, in part, on our ability to license leading
technologies useful in our business, enhance our existing services and develop
new services and technology that address the needs of our customers. We will
also need to respond to technological advances and emerging industry standards
in a cost-effective and timely basis.

OUR SUCCESS IS DEPENDENT ON OUR KEY PERSONNEL WHO WE MAY NOT BE ABLE TO RETAIN
AND WE MAY NOT BE ABLE TO HIRE ENOUGH ADDITIONAL PERSONNEL TO MEET OUR HIRING
NEEDS

  We believe that our success will depend on continued employment of our senior
management team and key technical personnel. If one or more members of our
senior management team were unable or unwilling to continue in their present
positions, our business, financial condition and operating results could be
materially adversely affected. Most of our senior management do not have
employment agreements. We carry key person life insurance on certain, but not on
all, of our senior management personnel.

  Our success also depends on having a highly trained sales force and telesales
group. Our telesales group was formed recently. We will need to continue to hire
additional personnel as our business grows. A shortage in the number of trained
salespeople could limit our ability to increase sales in our existing vertical
trade communities and to sell as we launch new vertical trade communities.

  We plan to expand our employee base to manage our anticipated growth.
Competition for personnel, particularly for employees with technical expertise,
is intense. Our business, financial condition and operating results will be
materially adversely affected if we cannot hire and retain suitable personnel.

OUR SYSTEMS MAY NOT BE YEAR 2000 COMPLIANT, WHICH COULD CAUSE OUR VERTICAL TRADE
COMMUNITIES TO BE UNAVAILABLE FOR A PERIOD OF TIME AFTER JANUARY 1, 2000, WHICH
COULD IN TURN HAVE A NEGATIVE IMPACT ON OUR BUSINESS, OPERATING RESULTS AND
FINANCIAL POSITION

  We may realize exposure and risk if the systems on which we are dependent to
conduct our operations are not Year 2000 compliant. Our potential areas of
exposure include products purchased from third parties, computers, software and
other equipment used internally. If our present efforts to address the Year 2000
compliance issues are not successful, or if distributors, suppliers and other
third parties with which we conduct business do not successfully address such
issues, our business, operating results and financial position could be
materially and adversely affected.

  In the event that our Web-hosting facilities are not Year 2000 compliant, our
production Web sites would be unavailable and we would not be able to deliver
services to our users. In the event that our production and operational
facilities that support our Web sites are not Year 2000 compliant, small
portions of our Web sites may become unavailable.

THE INTERESTS OF OUR CONTROLLING SHAREHOLDERS MAY CONFLICT WITH OUR INTERESTS
AND THE INTERESTS OF OUR OTHER SHAREHOLDERS

  As a result of its stock ownership and board representation, Internet Capital
Group, LLC is in a position to affect significantly our corporate actions such
as mergers or takeover attempts in a manner that could conflict with the
interests of our public shareholders. At June 30, 1999, Internet Capital Group
owns 6,147,505 shares, or 36.3%, of common stock. Internet Capital Group also
owns warrants to purchase 119,656 shares of common stock. Two representatives of
Internet Capital Group remain on our board of directors.

SHARES ELIGIBLE FOR FUTURE SALE BY OUR CURRENT SHAREHOLDERS MAY ADVERSELY AFFECT
OUR STOCK PRICE

                                       22
<PAGE>

  If our shareholders sell substantial amounts of our common stock, including
shares issued upon the exercise of outstanding options and warrants, in the
public market, then the market price of our common stock could fall.
Restrictions under the securities laws and certain lock-up agreements limit the
number of shares of common stock available for sale in the public market. In
connection with our recent initial public offering, the holders of 11,653,064
shares of common stock and warrants and options exercisable into an aggregate of
505,704 shares of common stock have agreed not to sell any such securities for
180 days after the initial public offering without the prior written consent of
Lehman Brothers, the lead underwriter of the initial public offering. However,
Lehman Brothers may, in its sole discretion, release all or any portion of the
securities subject to such lock-up agreements. The agreements expire on August
9, 1999.

  The holders of 10,047,346 shares of common stock and warrants to purchase
197,604 shares of common stock have demand and piggy-back registration rights.
The exercise of such rights could adversely affect the market price of our
common stock. We have also filed a registration statement to register all shares
of common stock under our stock option and employee stock purchase plans. That
registration statement was effective on February 10, 1999 and shares issued upon
exercise of stock options and employee stock purchase plans will be eligible for
resale in the public market without restriction.

ANTI-TAKEOVER PROVISIONS AND OUR RIGHT TO ISSUE PREFERRED STOCK COULD MAKE A
THIRD-PARTY ACQUISITION OF US DIFFICULT

  VerticalNet is a Pennsylvania corporation. Anti-takeover provisions of
Pennsylvania law could make it more difficult for a third party to acquire
control of us, even if such change in control would be beneficial to
shareholders. Our articles of incorporation provide that our board of directors
may issue preferred stock without shareholder approval. In addition, our bylaws
provide for a classified board, with each board member serving a staggered three
year term. The issuance of preferred stock and the existence of a classified
board could make it more difficult for a third-party to acquire us.

OUR COMMON STOCK PRICE IS LIKELY TO REMAIN HIGHLY VOLATILE

  The market price of our common stock has been and will likely continue to be
highly volatile as the stock market in general, and the market for Internet-
related and technology companies in particular, has been highly volatile.
Investors may not be able to resell their shares of our common stock following
periods of volatility because of the market's adverse reaction to such
volatility. The trading prices of many technology and Internet-related
companies' stocks have reached historical highs within the last 52 weeks and
have reflected relative valuations substantially above historical levels. During
the same period, such companies' stocks have also been highly volatile and have
recorded lows well below such historical highs. We cannot assure you that our
stock will trade at the same levels of other Internet stocks or that Internet
stocks in general will sustain their current market prices.

  Factors that could cause such volatility may include, among other things:

*  actual or anticipated variations in quarterly operating results;

*  announcements of technological innovations;

*  new sales formats or new products or services;

*  changes in financial estimates by securities analysts;

*  conditions or trends in the Internet industry;

*  changes in the market valuations of other Internet companies;

*  announcements by us or our competitors of significant acquisitions, strategic
partnerships or joint ventures;

*  capital commitments;

*  additions or departures of key personnel; and

*  sales of common stock.

  Many of these factors are beyond our control. These factors may materially
adversely affect the market price of our common stock, regardless of our
operating performance.

                                       23

ITEM 3.  QUALITATIVE AND QUANTITATIVE DISCLOSURE ABOUT MARKET RISK

Interest Rate Risk

  Our exposure to market risk related changes in interest rates relates
primarily to our investment portfolio.  We invest in instruments that meet high
credit quality standards, as specified in our investment policy.  The policy
also limits the amount of credit exposure to any one issue, issuer and type of
investment.

   As of June 30, 1999, our investments consisted of  $15.9 million that were
cash equivalents,  $12.5 million having a maturity of less than one year, and
$14.4 million that had a maturity of greater than one year.  Due to the average
maturity and conservative nature of our investment portfolio, a sudden change in
interest rates would not have a material effect on the value of the portfolio.
Management estimates that had the average yield of the Company's investments
decreased by 100 basis points, the Company's interest income for the quarter
ended June 30, 1999 would have decreased by less than $119,000.  This estimate
assumes that the decrease occurred on the first day of 1999 and reduced the
yield of each investment instrument by 100 basis points.  The impact on the
Company's future interest income and future changes in investment yields will
depend largely on the gross amount of the Company's investments.

ITEM 2.  CHANGE IN SECURITIES AND USE OF PROCEEDS

CHANGE IN SECURITIES

During the quarter, the Company issued the following shares of its common stock:

        *  On June 14, 1999, 44,997 shares were issued pursuant to the
           acquisition of Techspex, in exchange for the outstanding capital
           stock of Techspex held by 5 shareholders;
        *  On June 9, 1999, 2,921 shares were issued to the owner of Oillink, in
           exchange for the assets and liabilities assumed; and
        *  On June 29, 1999, 10,563 shares were issued to the owner of
           ElectricNet, in exchange for the assets and

The shares were issued pursuant to an exemption by reason of Section 4(2) of the
Securities Act of 1933. These sales were made without general solicitation or
advertising. Each purchaser represented that he, she, or it was acquiring the
shares without a view to distribute and that he, she, or it was afforded an
opportunity to review all publically filed documents and to ask questions, and
receive answers from, officers of the Company.

USE OF PROCEEDS

  On February 10, 1999, the Company's Registration Statement on Form S-1
covering the Offering of 4,025,000 shares of the Company's Common Stock,
Commission file number 333-68053 was declared effective.

                                       24
<PAGE>

  The net proceeds of the Offering to the Company (after deducting the foregoing
expenses) was $58,287,314. From the effective date of the Registration Statement
to June 30, 1999, the net proceeds have been used for the following purposes:


        Construction of plant, building and facilities        $         -
        Purchase and installation of machinery
         and equipment                                                  -
        Purchase of real estate                                         -
        Acquisition of other business (including
         transaction costs)                                     1,532,500

VERTICALNET, INC.

AMENDED AND RESTATED 1996 EQUITY COMPENSATION PLAN

1999 Amendment and Restatement as of  APRIL 13, 1999
- ----------------------------------------------------


     The purpose of the VerticalNet, Inc. Amended and Restated 1996 Equity
Compensation Plan (the "Plan") is to provide (i) designated employees of
VerticalNet, Inc. (the "Company") and its subsidiaries, (ii) certain consultants
and advisors who perform services for the Company or its subsidiaries and (iii)
non-employee members of the Board of Directors of the Company (the "Board") with
the opportunity to receive grants of incentive stock options, nonqualified stock
options and restricted stock.  The Company believes that the Plan will encourage
the participants to contribute materially to the growth of the Company, thereby
benefitting the Company's shareholders, and will align the economic interests of
the participants with those of the shareholders.

1.  Administration
    --------------

(a)     Authority.  Except as provided below, the Plan shall be administrated by
        ---------
a committee, which shall consist of two or more persons appointed by the Board,
all of whom may be "outside directors" as defined under section 162(m) of the
Internal Revenue Code of 1986, as amended (the "Code") and related Treasury
regulations, and "non-employee directors" as defined under Rule 16b-3 under the
Securities Exchange Act of 1934, as amended (the "Exchange Act").  The Board may
ratify or approve any grants made to participants.  References in the Plan to
the "Board", as they relate to Plan administration, shall be deemed to refer to
the committee or the Chief Executive Officer, as described in subsection (d)
below, if and to the extent that a committee or the Chief Executive Officer
administers the Plan.

(b)     Board Authority.  The Board shall have the sole authority to (i)
        ---------------
determine the individuals to whom grants shall be made under the Plan, (ii)
determine the type, size and terms of the grants to be made to each such
individual, (iii) determine the time when the grants will be made and the
duration of any applicable exercise or restriction period, including the
criteria for exercisability and the acceleration of exercisability and (iv) deal
with any other matters arising under the Plan.  The Board may require that a
grantee execute a shareholder's agreement, with such terms as the Board deems
appropriate, with respect to any Company stock distributed pursuant to this
Plan.

(c)     Board Determinations.  The Board shall have full power and authority to
        -------------------
administer and interpret the Plan, to make factual determinations and to adopt
or amend such rules, regulations, agreements and instruments for implementing
the Plan and for the conduct of its business as it deems necessary or advisable,
in its sole discretion.  The Board's interpretations of the Plan and all
determinations made by the Board pursuant to the powers vested in it hereunder
shall be conclusive and binding on all persons having any interest in the Plan
or in any awards granted hereunder.  All powers of the Board shall be executed
in its sole discretion, in the best interest of the Company, not as a fiduciary,
and in keeping with the objectives of the Plan and need not be uniform as to
similarly situated individuals.
<PAGE>

(d)     Delegation of Authority.  Notwithstanding the foregoing, the Board may
        -----------------------
delegate to the Chief Executive Officer of the Company the authority to make
grants under the Plan to employees of the Company and its subsidiaries who are
not subject to the restrictions of section 16(b) of the Exchange Act and who are
not expected to be subject to the limitations of section 162(m) of the Code.
The grant of authority under this subsection 1(d) shall be subject to such
conditions and limitations as may be determined by the Board.

2.      Grants
        ------

     Awards under the Plan may consist of grants of incentive stock options as
described in Section 5 ("Incentive Stock Options"), nonqualified stock options
as described in Section 5 ("Nonqualified Stock Options") (Incentive Stock
Options and Nonqualified Stock Options are collectively referred to as
"Options") or restricted stock as described in Section 6 (Restricted Stock")
(hereinafter collectively referred to as "Grants").  All Grants shall be subject
to the terms and conditions set forth herein and to such other terms and
conditions consistent with this Plan as the Board deems appropriate and as are
specified in writing by the Board to the individual in a grant instrument (the
"Grant Instrument") or an amendment to the Grant Instrument.  The Board shall
approve the form and provisions of each Grant Instrument.  Grants under a
particular Section of the Plan need not be uniform as among the grantees.

3.      Shares Subject to the Plan
        --------------------------

(a)     Shares Authorized.  Subject to the adjustment specified below, the
        -----------------
aggregate number of shares of common stock of the Company ("Company Stock") that
may be issued or transferred under the Plan is 3,600,000 shares, and the maximum
aggregate number of shares of Company Stock that shall be subject to Grants made
under the Plan to any individual during any calendar year shall be 500,000
shares.  The shares may be authorized but unissued shares of Company Stock or
reacquired shares of Company Stock, including shares purchased by the Company on
the open market for purposes of the Plan.  If and to the extent Options granted
under the Plan terminate, expire, or are canceled, forfeited, exchanged or
surrendered without having been exercised or if any shares of Restricted Stock
are forfeited, the shares subject to such Grants shall again be available for
purposes of the Plan.

(b)     Adjustments.  If there is any change in the number or kind of shares of
        -----------
Company Stock outstanding (i) by reason of a stock dividend, spinoff,
recapitalization, stock split, or combination or exchange of shares, (ii) by
reason of a merger, reorganization or consolidation in which the Company is the
surviving corporation, (iii) by reason of a reclassification or change in par
value, or (iv) by reason of any other extraordinary or unusual event affecting
the outstanding Company Stock as a class without the Company's receipt of
consideration, or if the value of outstanding shares of Company Stock is
substantially reduced as a result of a spinoff or the Company's payment of an
extraordinary dividend or distribution, the maximum number of shares of Company
Stock available for Grants, the maximum number of shares of Company Stock that
any individual participating in the Plan may be granted in any year, the number
of shares covered by outstanding Grants, the kind of shares issued under the
Plan, and the price per share or the applicable market value of such Grants may
be appropriately adjusted by the Board to reflect any increase or decrease in
the number of, or change in the kind or value of, issued shares of Company Stock
to preclude, to the extent practicable, the enlargement or dilution of rights
and benefits under such Grants; provided, however, that any fractional shares
resulting from such adjustment shall be eliminated.  Any adjustments determined
by the Board shall be final, binding and conclusive.

4.      Eligibility for Participation
        -----------------------------

(a)     Eligible Persons.  All employees of the Company and its subsidiaries
        ----------------
("Employees"), including Employees who are officers or members of the Board, and
members of the Board who are not Employees ("Non-Employee Directors") shall be
eligible to participate in the Plan. Consultants and advisors who perform
services to the Company or any of its subsidiaries ("Key Advisors")
<PAGE>

shall be eligible to participate in the Plan if the Key Advisors render bona
fide services and such services are not in connection with the offer or sale of
securities in a capital-raising transaction.

(b)     Selection of Grantees.  The Board shall select the Employees, Non-
        ---------------------
Employee Directors and Key Advisors to receive Grants and shall determine the
number of shares of Company Stock subject to a particular Grant in such manner
as the Board determines.  Employees, Key Advisors and Non-Employee Directors who
receive Grants under this Plan shall hereinafter be referred to as "Grantees".

5.      Granting of Options
        -------------------

(a)     Number of Shares.  The Board shall determine the number of shares of
        ----------------
Company Stock that will be subject to each Grant of Options to Employees, Non-
Employee Directors and Key Advisors.

(b)     Type of Option and Price.
        ------------------------

     (i) The Board may grant Incentive Stock Options that are intended to
qualify as "incentive stock options" within the meaning of section 422 of the
Code or Nonqualified Stock Options that are not intended so to qualify or any
combination of Incentive Stock Options and Nonqualified Stock Options, all in
accordance with the terms and conditions set forth herein.  Incentive Stock
Options may be granted only to Employees.  Nonqualified Stock Options may be
granted to Employees, Non-Employee Directors and Key Advisors.

     (ii) The purchase price (the "Exercise Price") of Company Stock subject to
an Option shall be determined by the Board and may be equal to, greater than, or
less than the Fair Market Value (as defined below) of a share of Company Stock
on the date the Option is granted; provided, however, that (x) the Exercise
Price of an Incentive Stock Option shall be equal to, or greater than, the Fair
Market Value of a share of Company Stock on the date the Incentive Stock Option
is granted and (y) an Incentive Stock Option may not be granted to an Employee
who, at the time of grant, owns stock possessing more than 10 percent of the
total combined voting power of all classes of stock of the Company or any parent
or subsidiary of the Company, unless the Exercise Price per share is not less
than 110% of the Fair Market Value of Company Stock on the date of grant.

     (iii)  If the Company Stock is publicly traded, then the Fair Market Value
per share shall be determined as follows: (x) if the principal trading market
for the Company Stock is a national securities exchange or the Nasdaq National
Market, the last reported sale price thereof on the relevant date or (if there
were no trades on that date) the latest preceding date upon which a sale was
reported, or (y) if the Company Stock is not principally traded on such exchange
or market, the mean between the last reported "bid" and "asked" prices of
Company Stock on the relevant date, as reported on Nasdaq or, if not so
reported, as reported by the National Daily Quotation Bureau, Inc. or as
reported in a customary financial reporting service, as applicable and as the
Board determines.  If the Company Stock is not publicly traded or, if publicly,
is not subject to reported transactions or "bid" or "asked" quotations as set
forth above, the Fair Market Value per share shall be as determined by the
Board.

(c)     Option Term.  The Board shall determine the term of each Option.  The
        -----------
term of any Option shall not exceed ten years from the date of grant.  However,
an Incentive Stock Option that is granted to an Employee who, at the time of
grant, owns stock possessing more than 10 percent of the total combined voting
power of all classes of stock of the Company, or any parent or subsidiary of the
Company, may not have a term that exceeds five years from the date of grant.

(d)     Exercisability of Options.  Options shall become exercisable in
        -------------------------
accordance with such terms and conditions, consistent with the Plan, as may be
determined by the Board and specified in the Grant Instrument or an amendment to
the Grant Instrument.  The Board may accelerate the exercisability of any or all
outstanding Options at any time for any reason.
<PAGE>

(e)     Termination of Employment, Disability or Death.
        ----------------------------------------------

        (i) Except as provided below, an Option may only be exercised while the
Grantee is employed by the Company as an Employee, Key Advisor or member of the
Board.  In the event that a Grantee ceases to be employed by the Company for any
reason other than a "disability", death, or "termination for cause", any Option
which is otherwise exercisable by the Grantee shall terminate unless exercised
within 90 days after the date on which the Grantee ceases to be employed by the
Company (or within such other period of time as may be specified by the Board),
but in any event no later than the date of expiration of the Option term.  Any
of the Grantee's Options that are not otherwise exercisable as of the date on
which the Grantee ceases to be employed by the Company shall terminate as of
such date.

        (ii) In the event the Grantee ceases to be employed by the Company on
account of a "termination for cause" by the Company, any Option held by the
Grantee shall terminate as of the date the Grantee ceases to be employed by the
Company.

        (iii) In the event the Grantee ceases to be employed by the Company
because the Grantee is "disabled", any Option which is otherwise exercisable by
the Grantee shall terminate unless exercised within one year after the date on
which the Grantee ceases to be employed by the Company (or within such other
period of time as may be specified by the Board), but in any event no later than
the date of expiration of the Option term. Any of the Grantee's Options which
are not otherwise exercisable as of the date on which the Grantee ceases to be
employed by the Company shall terminate as of such date.

        (iv) If the Grantee dies while employed by the Company or within 90 days
after the date on which the Grantee ceases to be employed on account of a
termination of employment specified in Section 5(e)(i) above (or within such
other period of time as may be specified by the Board), any Option that is
otherwise exercisable by the Grantee shall terminate unless exercised within one
year after the date on which the Grantee ceases to be employed by the Company
(or within such other period of time as may be specified by the Board), but in
any event no later than the date of expiration of the Option term.  Any of the
Grantee's Options that are not otherwise exercisable as of the date on which the
Grantee ceases to be employed by the Company shall terminate as of such date.

        (v) For purposes of this Section 5(e) and Section 6:

      (A) The term "Company" shall mean the Company and its parent and
     subsidiary corporations.

      (B) "Employed by the Company" shall mean employment or service as an
     Employee, Key Advisor or member of the Board (so that, for purposes of
     exercising Options and satisfying conditions with respect to Restricted
     Stock, a Grantee shall not be considered to have terminated employment or
     service until the Grantee ceases to be an Employee, Key Advisor and member
     of the Board), unless the Board determines otherwise.

      (C) "Disability" shall mean a Grantee's becoming disabled within the
     meaning of section 22(e)(3) of the Code.

      (D) "Termination for cause" shall mean, except to the extent specified
     otherwise by the Board, a finding by the Board that the Grantee has
     breached his or her employment or service contract with the Company, or has
     been engaged in disloyalty to the Company, including, without limitation,
     fraud, embezzlement, theft, commission of a felony or proven dishonesty in
     the course of his or her employment or service, or has disclosed trade
     secrets or confidential information of the Company to persons not entitled
     to receive such information.  In the event a Grantee's employment is
     terminated for cause, in addition to the immediate termination of all
     Grants, the Grantee shall automatically forfeit all shares underlying any
     exercised portion of an
<PAGE>

     Option for which the Company has not yet delivered the share certificates,
     upon refund by the Company of the Exercise Price paid by the Grantee for
     such shares.

(f)     Exercise of Options.  A Grantee may exercise an Option that has become
        -------------------
exercisable, in whole or in part, by delivering a notice of exercise to the
Company with payment of the Exercise Price.  The Grantee shall pay the Exercise
Price for an Option as specified by the Board (x) in cash, (y) with the approval
of the Board, by delivering shares of Company Stock owned by the Grantee
(including Company Stock acquired in connection with the exercise of an Option,
subject to such restrictions as the Board deems appropriate) and having a Fair
Market Value on the date of exercise equal to the Exercise Price or (z) by such
other method as the Board may approve, including payment through a broker in
accordance with procedures permitted by Regulation T of the Federal Reserve
Board.  Shares of Company Stock used to exercise an Option shall have been held
by the Grantee for the requisite period of time to avoid adverse accounting
consequences to the Company with respect to the Option.  The Grantee shall pay
the Exercise Price and the amount of any withholding tax due (pursuant to
Section 7) at the time of exercise.

(g)     Limits on Incentive Stock Options.  Each Incentive Stock Option shall
        ---------------------------------
provide that, if the aggregate Fair Market Value of the stock on the date of the
grant with respect to which Incentive Stock Options are exercisable for the
first time by a Grantee during any calendar year, under the Plan or any other
stock option plan of the Company or a parent or subsidiary, exceeds $100,000,
then the option, as to the excess, shall be treated as a Nonqualified Stock
Option.  An Incentive Stock Option shall not be granted to any person who is not
an Employee of the Company or a parent or subsidiary (within the meaning of
section 424(f) of the Code).

6.      Restricted Stock Grants
        -----------------------

     The Board may issue or transfer shares of Company Stock to an Employee,
Non-Employee Director or Key Advisor under a Grant of Restricted Stock, upon
such terms as the Board deems appropriate.  The following provisions are
applicable to Restricted Stock:



(a)     General Requirements.  Shares of Company Stock issued or transferred
        --------------------
pursuant to Restricted Stock Grants may be issued or transferred for
consideration or for no consideration, as determined by the Board.  The Board
may establish conditions under which restrictions on shares of Restricted Stock
shall lapse over a period of time or according to such other criteria as the
Board deems appropriate.  The period of time during which the Restricted Stock
will remain subject to restrictions will be designated in the Grant Instrument
as the "Restriction Period."

(b)     Number of Shares.  The Board shall determine the number of shares of
        ----------------
Company Stock to be issued or transferred pursuant to a Restricted Stock Grant
and the restrictions applicable to such shares.

(c)     Requirement of Employment.  If the Grantee ceases to be employed by the
        -------------------------
Company (as defined in Section 5(e)) during a period designated in the Grant
Instrument as the Restriction Period, or if other specified conditions are not
met, the Restricted Stock Grant shall terminate as to all shares covered by the
Grant as to which the restrictions have not lapsed, and those shares of Company
Stock must be immediately returned to the Company.  The Board may, however,
provide for complete or partial exceptions to this requirement as it deems
appropriate.

(d)     Restrictions on Transfer and Legend on Stock Certificate.  During the
        --------------------------------------------------------
Restriction Period, a Grantee may not sell, assign, transfer, pledge or
otherwise dispose of the shares of Restricted Stock except to a Successor
Grantee under Section 8(a).  Each certificate for a share of Restricted Stock
shall contain a legend giving appropriate notice of the restrictions in the
Grant.  The
<PAGE>

Grantee shall be entitled to have the legend removed from the stock certificate
covering the shares subject to restrictions when all restrictions on such shares
have lapsed. The Board may determine that the Company will not issue
certificates for shares of Restricted Stock until all restrictions on such
shares have lapsed, or that the Company will retain possession of certificates
for shares of Restricted Stock until all restrictions on such shares have
lapsed.

(e)     Right to Vote and to Receive Dividends.  Unless the Board determines
        --------------------------------------
otherwise, during the Restriction Period,  the Grantee shall have the right to
vote shares of Restricted Stock and to receive any dividends or other
distributions paid on such shares, subject to any restrictions deemed
appropriate by the Board.

(f)     Lapse of Restrictions.  All restrictions imposed on Restricted Stock
        ---------------------
shall lapse upon the expiration of the applicable Restriction Period and the
satisfaction of all conditions imposed by the Board.  The Board may determine,
as to any or all Restricted Stock Grants, that the restrictions shall lapse
without regard to any Restriction Period.

7.      Withholding of Taxes
        --------------------

(a)     Required Withholding.  All Grants under the Plan shall be subject to
        --------------------
applicable federal (including FICA), state and local tax withholding
requirements.  The Company may require the Grantee or other person receiving
shares under the Plan to pay to the Company the amount of any such taxes that
the Company is required to withhold with respect to the Grant, or the Company
may deduct from other wages paid by the Company the amount of any withholding
taxes due with respect to the Grant.

(b)     Election to Withhold Shares.  If the Board so permits, a Grantee may
        ---------------------------
elect to satisfy the Company's income tax withholding obligation with respect to
an Option or Restricted Stock by having shares withheld up to an amount that
does not exceed the applicable withholding tax rate for federal (including
FICA), state and local tax liabilities.  The election must be in a form and
manner prescribed by the Board and shall be subject to the prior approval of the
Board.

8.      Transferability of Grants
        -------------------------

(a)     Nontransferability of Grants.  Except as provided below, only the
        ----------------------------
Grantee may exercise rights under a Grant during the Grantee's lifetime.  A
Grantee may not transfer those rights except by will or by the laws of descent
and distribution or, with respect to Grants other than Incentive Stock Options,
if permitted in any specific case by the Board, pursuant to a domestic relations
order.  When a Grantee dies, the personal representative or other person
entitled to succeed to the rights of the Grantee ("Successor Grantee") may
exercise such rights.  A Successor Grantee must furnish proof satisfactory to
the Company of his or her right to receive the Grant under the Grantee's will or
under the applicable laws of descent and distribution.

(b)     Transfer of Nonqualified Stock Options. Notwithstanding the foregoing,
        --------------------------------------
the Board may provide, in a Grant Instrument, that a Grantee may transfer
Nonqualified Stock Options to family members or other persons or entities
according to such terms as the Board may determine; provided that the
transferred Option shall continue to be subject to the same terms and conditions
as were applicable to the Option immediately before the transfer.

9.      Change of Control of the Company
        --------------------------------

     As used herein, a "Change of Control" shall be deemed to have occurred if:

(a)     Any "person" (as such term is used in Sections 13(d) and 14(d) of the
Exchange Act) becomes a "beneficial owner" (as defined in Rule 13d-3 under the
Exchange Act), directly or
<PAGE>

indirectly, of securities of the Company representing more than 50% of the
voting power of the then outstanding securities of the Company; or

(b)     The shareholders of the Company approve (or, if shareholder approval is
not required, the Board approves) an agreement providing for (i) the merger or
consolidation of the Company with another corporation where the shareholders of
the Company, immediately prior to the merger or consolidation, will not
beneficially own, immediately after the merger or consolidation, shares
entitling such shareholders to more than 50% of all votes to which all
shareholders of the surviving corporation would be entitled in the election of
directors (without consideration of the rights of any class of stock to elect
directors by a separate class vote),  (ii) the sale or other disposition of all
or substantially all of the assets of the Company, or (iii) a liquidation or
dissolution of the Company.

10.     Consequences of a Change of Control
        -----------------------------------

(a)     Notice and Acceleration.  Upon a Change of Control, unless the Board
        -----------------------
determines otherwise, (i) the Company shall provide each Grantee with
outstanding Grants written notice of such Change of Control, (ii) all
outstanding Options shall automatically accelerate and become fully exercisable,
and (iii) the restrictions and conditions on all outstanding Restricted Stock
shall immediately lapse.

(b)     Assumption of Grants.  Upon a Change of Control where the Company is not
        --------------------
the surviving corporation (or survives only as a subsidiary of another
corporation), unless the Board determines otherwise, all outstanding Grants
shall be assumed by, or replaced with comparable options or stock by, the
surviving corporation.

(c)     Other Alternatives.  Notwithstanding the foregoing, subject to
        ------------------
subsection (d) below, in the event of a Change of Control, the Board may take
one or both of the following actions: the Board may (i) require that Grantees
surrender their outstanding Options in exchange for a payment by the Company, in
cash or Company Stock as determined by the Board, in an amount equal to the
amount by which the then Fair Market Value of the shares of Company Stock
subject to the Grantee's unexercised Options exceeds the Exercise Price of the
Options, or (ii) after giving Grantees an opportunity to exercise their
outstanding Options, terminate any or all unexercised Options at such time as
the Board deems appropriate.  Such surrender or termination shall take place as
of the date of the Change of Control or such other date as the Board may
specify.

(d)     Limitations.  Notwithstanding anything in the Plan to the contrary, in
        -----------
the event of a Change of Control, the Board shall not have the right to take any
actions described in the Plan (including without limitation actions described in
Subsection (c) above) that would make the Change of Control ineligible for
pooling of interests accounting treatment or that would make the Change of
Control ineligible for desired tax treatment if, in the absence of such right,
the Change of Control would qualify for such treatment and the Company intends
to use such treatment with respect to the Change of Control.

11.     Requirements for Issuance or Transfer of Shares
        -----------------------------------------------

(a)     Limitations on Issuance or Transfer of Shares.  No Company Stock shall
        ---------------------------------------------
be issued or transferred in connection with any Grant hereunder unless and until
all legal requirements applicable to the issuance or transfer of such Company
Stock have been complied with to the satisfaction of the Board.  The Board shall
have the right to condition any Grant made to any Grantee hereunder on such
Grantee's undertaking in writing to comply with such restrictions on his or her
subsequent disposition of such shares of Company Stock as the Board shall deem
necessary or advisable as a result of any applicable law, regulation or official
interpretation thereof, and certificates representing such shares may be
legended to reflect any such restrictions.  Certificates representing shares of
Company Stock issued or transferred under the Plan will be subject to such stop-
transfer orders and other restrictions as may be
<PAGE>

required by applicable laws, regulations and interpretations, including any
requirement that a legend be placed thereon.

12.     Amendment and Termination of the Plan
        -------------------------------------

(a)     Amendment.  The Board may amend or terminate the Plan at any time;
        ---------
provided, however, that the Board shall not amend the Plan without shareholder
approval if such approval is required by Section 162(m) of the Code.

(b)     Termination of Plan.  The Plan shall terminate on the day immediately
        -------------------
preceding the tenth anniversary of its effective date, unless the Plan is
terminated earlier by the Board or is extended by the Board with the approval of
the shareholders.

(c)     Termination and Amendment of Outstanding Grants.  A termination or
        -----------------------------------------------
amendment of the Plan that occurs after a Grant is made shall not materially
impair the rights of a Grantee unless the Grantee consents or unless the Board
acts under Section 18(b).  The termination of the Plan shall not impair the
power and authority of the Board with respect to an outstanding Grant.  Whether
or not the Plan has terminated, an outstanding Grant may be terminated or
amended under Section 18(b) or may be amended by agreement of the Company and
the Grantee consistent with the Plan.

(d)     Governing Document.  The Plan shall be the controlling document.  No
        ------------------
other statements, representations, explanatory materials or examples, oral or
written, may amend the Plan in any manner.  The Plan shall be binding upon and
enforceable against the Company and its successors and assigns.

13.     Funding of the Plan
        -------------------

     This Plan shall be unfunded.  The Company shall not be required to
establish any special or separate fund or to make any other segregation of
assets to assure the payment of any Grants under this Plan.  In no event shall
interest be paid or accrued on any Grant, including unpaid installments of
Grants.

14.     Rights of Participants
        ----------------------

     Nothing in this Plan shall entitle any Employee, Key Advisor, Non-Employee
Director or other person to any claim or right to be granted a Grant under this
Plan.  Neither this Plan nor any action taken hereunder shall be construed as
giving any individual any rights to be retained by or in the employ of the
Company or any other employment rights.

15.     No Fractional Shares
        --------------------

     No fractional shares of Company Stock shall be issued or delivered pursuant
to the Plan or any Grant.  The Board shall determine whether cash, other awards
or other property shall be issued or paid in lieu of such fractional shares or
whether such fractional shares or any rights thereto shall be forfeited or
otherwise eliminated.

16.     Headings
        --------

     Section headings are for reference only.  In the event of a conflict
between a title and the content of a Section, the content of the Section shall
control.

17.     Effective Date of the Plan.
        --------------------------

     Subject to the approval of the Company's shareholders, the Plan shall be
effective on December 18, 1996.  The amendment and restatement of the Plan shall
be effective as of April 13, 1999.
<PAGE>

18.     Miscellaneous
        -------------

(a)     Grants in Connection with Corporate Transactions and Otherwise.
        --------------------------------------------------------------
Nothing contained in this Plan shall be construed to (i) limit the right of the
Board to make Grants under this Plan in connection with the acquisition, by
purchase, lease, merger, consolidation or otherwise, of the business or assets
of any corporation, firm or association, including Grants to employees thereof
who become Employees of the Company, or for other proper corporate purposes, or
(ii) limit the right of the Company to grant stock options or make other awards
outside of this Plan.  Without limiting the foregoing, the Board may make a
Grant to an employee of another corporation who becomes an Employee by reason of
a corporate merger, consolidation, acquisition of stock or property,
reorganization or liquidation involving the Company or any of its subsidiaries
in substitution for a stock option or restricted stock grant made by such
corporation.  The terms and conditions of the substitute grants may vary from
the terms and conditions required by the Plan and from those of the substituted
stock incentives.  The Board shall prescribe the provisions of the substitute
grants.

(b)     Compliance with Law.  The Plan, the exercise of Options and the
        -------------------
obligations of the Company to issue or transfer shares of Company Stock under
Grants shall be subject to all applicable laws and to approvals by any
governmental or regulatory agency as may be required.  With respect to persons
subject to Section 16 of the Exchange Act, it is the intent of the Company that
the Plan and all transactions under the Plan comply with all applicable
provisions of Rule 16b-3 or its successors under the Exchange Act.  The Board
may revoke any Grant if it is contrary to law or modify a Grant to bring it into
compliance with any valid and mandatory government regulation.  The Board may
also adopt rules regarding the withholding of taxes on payments to Grantees.
The Board may, in its sole discretion, agree to limit its authority under this
Section.

(c)     Governing Law.  The validity, construction, interpretation and effect of
        -------------
the Plan and Grant Instruments issued under the Plan shall exclusively be
governed by and determined in accordance with the law of the Commonwealth of
Pennsylvania.

2. Premises. Landlord hereby leases to Tenant and Tenant hereby leases from
   --------
Landlord the Premises as shown on attached Exhibit "A" within the Building (the
Building and the lot on which it is located, the "PROPERTY"), together with the
non-exclusive right with Landlord and other occupants of the Building to use all
areas and facilities provided by Landlord for the use of all tenants in the
Property including any lobbies, hallways, driveways, sidewalks and parking,
loading and landscaped areas (the "COMMON AREAS").

3. Acceptance of Premises. Tenant has examined and knows the condition of the
   ----------------------
Property, the zoning, streets, sidewalks, parking areas, curbs and access ways
adjoining it, visible easements, any surface conditions and the present uses,
and Tenant accepts them in the condition in which they now are, without relying
on any representation, covenant or warranty by Landlord. Tenant and its agents
shall have the right, at Tenant's own risk, expense and responsibility, at all
reasonable times prior to the Commencement Date, to enter the Premises for the
purpose of taking measurements and installing its furnishings and equipment,
provided that the Premises are vacant and Tenant obtains Landlord's prior
written consent.

4.   Use; Compliance.
     ---------------
     (a) Permitted Use. Tenant shall occupy and use the Premises for and only
for the Use specified in Section 1(f) above and in such a manner as is lawful,
reputable and will not create any nuisance or otherwise interfere with any other
tenant's normal operations or the management of the Building. Without limiting
the foregoing, such Use shall exclude any use that would cause the Premises or
the Property to be deemed a "place of public accommodation" under the Americans
with Disabilities Act (the "ADA") as further described in the Building Rules

REQUIREMENTS") and the building rules attached as Exhibit "C" as amended by
Landlord from time to time (the "BUILDING RULES"). Provided, however, that
Tenant shall not be required to comply with the Laws and Requirements with
respect to the footings, foundations, structural steel columns and girders

5. Term. The Term of this lease shall commence on the Commencement Date and
   ----
shall end at 11:59 p.m. on the last day of the Term (the "EXPIRATION DATE"),
without the necessity for notice from either party, unless sooner terminated in
accordance with the terms hereof. At Landlord's request, Tenant shall confirm
the Commencement Date and Expiration Date by executing a lease commencement
certificate in the form attached as Exhibit "B".

6. Minimum Annual Rent. Tenant agrees to pay to Landlord the Minimum Annual Rent
   -------------------
in equal monthly installments in the amount set forth in Section 1(d) (as
increased at the beginning of each lease year as set forth in Section 1(d)), in
advance, on the first day of each calendar month during the Term, without
notice, demand or setoff, at Landlord's address designated at the beginning of
this lease unless Landlord designates otherwise, provided that rent for the
first full month shall be paid at the signing of this lease. If the Commencement
Date falls on a day other than the first day of a calendar month, the rent shall
be apportioned pro rata on a per diem basis for the period from the Commencement
Date until the first day of the following calendar month and shall be paid on or
before the Commencement Date. As used in this lease, the term "lease year" means
the period from the Commencement Date

                                       2
<PAGE>

through the succeeding 12 full calendar months (including for the first lease
year any partial month from the Commencement Date until the first day of the
first full calendar month) and each successive 12 month period thereafter during
the Term.

7.   Operation of Property; Payment of Expenses.
     ------------------------------------------

     (a) Payment of Operating Expenses. Tenant shall pay to Landlord the Annual
Operating Expenses in equal monthly installments in the amount set forth in
Section 1(d) (prorated for any partial month), from the Commencement Date and
continuing throughout the Term on the first day of each calendar month during
the Term, as additional rent, without notice, demand or setoff provided that the
monthly installment for the first full month shall be paid at the signing of
this lease. Landlord shall apply such payments to the annual operating costs to
Landlord of operating and maintaining the Property during each calendar year of
the Term, which costs may include by way of example rather than limitation:
insurance premiums, fees, impositions, costs for repairs, maintenance, service
contracts, management and administrative fees, governmental permits, overhead
expenses, costs of furnishing water, sewer, gas, fuel, electricity, other
utility services, janitorial service, trash removal, security services,
landscaping and grounds maintenance, and the costs of any other items
attributable to operating or maintaining any or all of the Property excluding
any costs which under generally accepted accounting principles are capital
expenditures, provided, however, that annual operating costs also shall include
the annual amortization (over an assumed useful life of ten years) of the costs
(including financing charges) of building improvements made by Landlord to the
Property that are required by any governmental authority or for the purpose of
reducing operating expenses or directly enhancing the safety of tenants in the
Building generally. The amount of the Annual Operating Expenses set forth in
Section 1(d) represents Landlord's estimate of Tenant's share of the estimated
operating costs during the first calendar year of the Term on an annualized
basis, from time to time Landlord may adjust such estimated amount if the
estimated operating costs increase Tenant's obligation to pay the Annual
Operating Expenses pursuant to this Section 7 shall survive the expiration or
termination of this lease.

          (i) Computation of Tenant's Share of Annual Operating Costs. After the
     end of each calendar year of the Term, Landlord shall compute Tenant's
     share of the annual operating costs described above incurred during such
     calendar year by (A) calculating an appropriate adjustment, using generally
     accepted accounting principles, to avoid allocating to Tenant or to any
     other tenant (as the case may be) those specific costs which Tenant or any
     other tenant has agreed to pay, (B) calculating an appropriate adjustment,
     using generally accepted accounting principles, to avoid allocating to any
     vacant space those specific costs which were not incurred for such space,
     and (C) multiplying the adjusted annual operating costs by Tenant's
     Proportionate Share.

          (ii) Reconciliation. By April 30th of each year (and as soon as
     practical after the expiration or termination of this lease or at any time
     in the event of a sale of the Property), Landlord shall provide Tenant with
     a statement of the actual amount of such annual operating costs for the
     preceding calendar year or part thereof. Landlord or Tenant shall pay to
     the other the amount of any deficiency or overpayment then due from one to
     the other or at Landlord's option. Landlord may credit Tenant's account for
     any overpayment. Tenant shall have the right to inspect the books and
     records used by Landlord in calculating the annual operating costs within
     60 days of receipt of the statement during regular business hours after
     having given Landlord at least 48 hours prior written notice, provided,
     however, that Tenant shall make all payments of additional rent without
     delay, and that Tenant's obligation to pay such additional rent shall not
     be contingent on any such right.

     (b) Impositions. As used in this lease the term "impositions" refers to all
levies, taxes (including sales taxes and gross receipt taxes) and assessments,
which are applicable to the Term, and which are imposed by any authority or
under any law, ordinance or regulation thereof, or pursuant to any recorded
covenants or agreements, and the reasonable cost of contesting any of the
foregoing, upon or with respect to the Property or any part thereof, or any
improvements thereto. Tenant shall pay to Landlord with the monthly payment of
Minimum Annual Rent any imposition imposed directly upon this lease or the Rent
(defined in Section 7(g)) or amounts payable on any subtenants or other
occupants of the Premises, or against Landlord because of Landlord's estate or
interest herein.

          (i) Nothing herein contained shall be interpreted as requiring Tenant
     to pay any income, excess profits or corporate capital stock tax imposed or
     assessed upon Landlord, unless such tax or any similar tax is levied or
     assessed in lieu of all or any part of any imposition or an increase in any
     imposition.

          (ii) If it shall not be lawful for Tenant to reimburse Landlord for
     any of the impositions, the Minimum Annual Rent shall be increased by the
     amount of the portion of such imposition allocable to Tenant, unless
     prohibited by law.

     (c)  Insurance.

          (i) Property. Landlord shall keep in effect insurance against loss or
     damage to the Building or the Property by fire and such other casualties as
     may be included within fire, extended coverage and special form insurance
     covering the full replacement

                                       3
<PAGE>

     cost of the Building (but excluding coverage of Tenant's personal property
     in, and any alterations by Tenant to, the Premises) and such other
     insurance as Landlord may reasonably deem appropriate or as may be required
     from time-to-time by any mortgagee.

          (ii) Liability. Tenant, at its own expense, shall keep in effect
     comprehensive general public liability insurance with respect to the
     Premises and the Property, including contractual liability insurance, with
     such limits of liability for bodily injury including death and property
     damage as reasonably may be required by Landlord from time-to-time, but not
     less than a combined single limit of $1,000,000 per occurrence and a
     general aggregate limit of not less than $2,000,000 (which aggregate limit
     shall apply separately to each of Tenant's locations if more than the
     Premises); however, such limits shall not limit the liability of Tenant
     hereunder. The policy of comprehensive general public liability insurance
     also shall name Landlord and Landlord's agent as insured parties with
     respect to the Premises, shall be written on an "occurrence" basis and not
     on a "claims made" basis, shall provide that it is primary with respect to
     any policies carried by Landlord and that any coverage carried by Landlord
     shall be excess insurance, shall provide that it shall not be cancelable or
     reduced without at least 30 days prior written notice to Landlord and shall
     be issued in form satisfactory to Landlord. The insurer shall be a
     responsible insurance carrier which is authorized to issue such insurance
     and licensed to do business in the state in which the Property is located
     and which has at all times during the Term a rating of no less than
     A VII in the most current edition of Best's Insurance Reports. Tenant
     shall deliver to Landlord on or before the Commencement Date, and
     subsequently renewals of a certificate of insurance evidencing such
     coverage and the waiver of subrogation described below

          (iii) Waiver of Subrogation. Landlord and Tenant shall have included
     in their respective property insurance policies waivers of their respective
     insurers' right of subrogation against the other party.  If such a waiver
     should be unobtainable or unenforceable, then such policies of insurance
     shall state expressly that such policies shall not be invalidated if,
     before a casualty, the insured waives the right of recovery against any
     party responsible for a casualty covered by the policy.

          (iv) Increase of Premiums. Tenant agrees not to do anything or fail to
     do anything which will increase the cost of Landlord's insurance or which
     will prevent Landlord from procuring policies (including public liability)
     from companies and in a form satisfactory to Landlord. If any breach of the
     preceding sentence by Tenant causes the rate of fire or other insurance to
     be increased, Tenant shall pay the amount of such increase as additional
     rent promptly upon being billed.

     (d) Repairs and Maintenance; Common Areas; Building Management.

          (i) Tenant at its sole expense shall maintain the Premises in a neat
     and orderly condition.

          (ii) Landlord, shall make all necessary repairs to the Premises, the
     Common Areas and any other improvements located on the Property provided
     that Landlord shall have no responsibility to make any repair until
     Landlord receives written notice of the need for such repair. Landlord
     shall operate and manage the Property and shall maintain all Common Areas
     and any paved areas appurtenant to the Property in a clean and orderly
     condition. Landlord reserves the right to make alterations to the Common
     Areas from time to time.

          (iii) Notwithstanding anything herein to the contrary, repairs and
     replacements to the Property including the Premises made necessary by
     Tenant's use, occupancy or alteration of or Tenant's installation in or
     upon the Property or by any act or omission of Tenant or its Agents shall
     be made at the sole expense of Tenant to the extent not covered by any
     applicable insurance proceeds paid to Landlord. Tenant shall not bear the
     expense of any repairs or replacements to the Property arising out of or
     caused by any other tenant's use, occupancy or alteration of or any other
     tenant's installation in or upon, the Property or by any act or omission of
     any other tenant or any other tenant's Agents.

     (e)  Utilities.

          (i) Landlord will furnish the Premises with electricity, heating and
     air conditioning for the normal use and occupancy of the Premises as
     general offices between 8:00 a.m. and 6:00 p.m., Monday through Friday
     (legal holidays excepted). If Tenant shall require electricity or install
     electrical equipment including but not limited to electrical heating,
     refrigeration equipment, electronic data processing machines, or machines
     or equipment using current in excess of 110 volts, which will in any way
     increase the amount of electricity usually furnished for use as general
     office space, or if Tenant shall attempt to use the Premises in such a
     manner that the services to be furnished by Landlord would be required
     during periods other than or in addition to business hours referred to
     above, Tenant will obtain Landlord's prior written approval and will pay
     for the resulting additional direct expense, including the expense
     resulting from the installation of such equipment and meters, as additional
     rent promptly upon being billed. Landlord shall not be responsible or
     liable for any interruption in utility service, nor shall such interruption
     affect the continuation or validity of this lease.

                                       4
<PAGE>

          (ii) If at any time utility services supplied to the Premises are
     separately metered, the cost of installing Tenant's meter and the cost of
     such separately metered utility service shall be paid by Tenant promptly
     upon being billed.

     (f) Janitorial Services. Landlord will provide Tenant with trash removal
and janitorial services pursuant to a cleaning schedule attached as Exhibit "D".

     (g) "Rent." The term "RENT" as used in this lease means the Minimum Annual
Rent, Annual Operating Expenses and any other additional rent or sums payable by
Tenant to Landlord pursuant to this lease, all of which shall be deemed rent for
purposes of Landlord's rights and remedies with respect thereto. Tenant shall
pay all Rent to Landlord within 30 days after Tenant is billed, unless otherwise
provided in this lease, and interest shall accrue on all sums due but unpaid.

8.   Signs. Landlord, at Landlord's expense, will place Tenant's name and suite
     -----
number on the Building standard sign and on or beside the entrance door to the
Premises. Except for signs which are located wholly within the interior of the
Premises and not visible from the exterior of the Premises, no signs shall be
placed on the Property without the prior written consent of Landlord. All signs
installed by Tenant shall be maintained by Tenant in good condition and Tenant
shall remove all such signs at the termination of this lease and shall repair
any damage caused by such installation, existence or removal.

9.   Alterations and Fixtures.
     ------------------------

     (a) Subject to Section 10. Tenant shall have the right to install its trade
fixtures in the Premises, provided that no such installation or removal thereof
shall affect any structural portion of the Property nor any utility lines,
communications lines, equipment or facilities in the Building serving any tenant
other than Tenant. At the expiration or termination of this lease and at the
option of Landlord or Tenant, Tenant shall remove such installation(s) and, in
the event of such removal, Tenant shall repair any damage caused by such
installation or removal; if Tenant, with Landlord's written consent, elects not
to remove such installation(s) at the expiration or termination of this lease,
all such installations shall remain on the Property and become the property of
Landlord without payment by Landlord.

     (b) Except for non-structural changes which do not exceed $5000 in the
aggregate, Tenant shall not make or permit to be made any alterations to the
Premises without Landlord's prior written consent. Tenant shall pay the costs of
any required architectural engineering reviews. In making any alterations, (i)

utility lines, communications lines, equipment or facilities in the Building
serving any tenant other than Tenant, (iii) Tenant shall comply with Section 10

property of Tenant until the expiration or termination of this lease, at that
time all such alterations shall remain on the Property and become the property
of Landlord without payment by Landlord unless Landlord gives written notice to
Tenant to remove the same, in which event Tenant will remove such alterations
and repair any resulting damage. At Tenant's request prior to Tenant making any
alterations, Landlord shall notify Tenant in writing, whether Tenant is required
to remove such alterations at the expiration or termination of this lease.

10.  Mechanics' Liens. Tenant shall pay promptly any contractors and materialmen
     ----------------
who supply labor, work or materials to Tenant at the Property and shall take all
steps permitted by law in order to avoid the imposition of any mechanic's lien
upon all or any portion of the Property. Should any such lien or notice of lien
be filed for work performed for Tenant other than by Landlord, Tenant shall bond
against or discharge the same within 5 days after Tenant has notice that the
lien or claim is filed regardless of the validity of such lien or claim. Nothing
in this lease is intended to authorize Tenant to do or cause any work to be done
or materials to be supplied for the account of Landlord, all of the same to be
solely for Tenant's account and at Tenant's risk and expense. Throughout this
lease the term "mechanic's lien" is used to include any lien, encumbrance or
charge levied or imposed upon all or any portion of interest in or income from
the Property on account of any mechanic's, laborer's, materialman's or
construction lien or arising out of any debt or liability to or any claim of any
contractor, mechanic, supplier, materialman or laborer and shall include any
mechanic's notice of intention to file a lien given to Landlord or Tenant, any
stop order given to Landlord or Tenant, any notice of refusal to pay naming
Landlord or Tenant and any injunctive or equitable action brought by any person
claiming to be entitled to any mechanic's lien

11.  Landlord's Right to Relocate Tenant; Right of Entry.
     ---------------------------------------------------

     (a) Landlord may cause Tenant to relocate from the Premises to a comparable
space ("RELOCATION SPACE") within the Building by giving written notice to
Tenant at least 60 days in advance, provided that Landlord shall pay for all
reasonable costs of


                                       5
<PAGE>

such relocation.  Such a relocation shall not terminate, modify or otherwise
affect this lease except that "Premises" shall refer to the Relocation Space
rather than the old location identified in Section 1(a).

     (b) Tenant shall permit Landlord and its Agents to enter the Premises at
all reasonable times following reasonable notice (except in the event of an
emergency), for the purpose of inspection, maintenance or making repairs,
alterations or additions as well as to exhibit the Premises for the purpose of
sale or mortgage and, during the last 12 months of the Term, to exhibit the
Premises to any prospective tenant. Landlord will make reasonable efforts not to
inconvenience Tenant in exercising the foregoing rights but shall not be liable
for any loss of occupation or quiet enjoyment thereby occasioned.

12.  Damage by Fire or Other Casualty.
     --------------------------------

     (a) If the Premises or Building shall be damaged or destroyed by fire or
other casualty, Tenant promptly shall notify Landlord and Landlord, subject to
the conditions set forth in this Section 12, shall repair such damage and
restore the Premises to substantially the same condition in which they were
immediately prior to such damage or destruction, but not including the repair,
restoration or replacement of the fixtures or alterations installed by Tenant.
Landlord shall notify Tenant in writing, within 30 days after the date of the
casualty if Landlord anticipates that the restoration will take more than 180
days from the date of the casualty to complete, in such event, either Landlord
or Tenant may terminate this lease effective as of the date of casualty by
giving written notice to the other within 10 days after Landlord's notice.
Further, if a casualty occurs during the last 12 months of the Term or any
extension thereof, Landlord may cancel this lease unless Tenant has the right to
extend the Term for at least 3 more years and does so within 30 days after the
date of the casualty.

     (b) Landlord shall maintain a 12 month rental coverage endorsement or other
comparable form of coverage as part of its fire, extended coverage and special
form insurance. Tenant will receive an abatement of its Minimum Annual Rent and
Annual Operating Expenses to the extent the Premises are rendered untenantable
as determined by the carrier providing the rental coverage endorsement.

13.  Condemnation.
     ------------

     (a) Termination. If (i) all of the Premises are taken by a condemnation or
otherwise for any public or quasi-public use, (ii) any part of the Premises is
so taken and the remainder thereof is insufficient for the reasonable operation
of Tenants business or (iii) any of the Property is so taken, and, in Landlord's
opinion, it would be impractical or the condemnation proceeds are insufficient
to restore the remainder of the Property, then this lease shall terminate and
all unaccrued obligations hereunder shall cease as of the day before possession
is taken by the condemnor.

     (b) Partial Taking. If there is a condemnation and this lease has not been
terminated pursuant to this Section, (i) Landlord shall restore the Building and
the improvements which area part of the Premises to a condition and size as
nearly comparable as reasonably possible to the condition and size thereof
immediately prior to the date upon which the condemnor took possession and (ii)
the obligations of Landlord and Tenant shall be unaffected by such condemnation
except that there shall be an equitable abatement of the Minimum Annual Rent
according to the rental value of the Premises before and after the date upon
which the condemnor took possession and/or the date Landlord completes such
restoration.

     (c) Award. In the event of a condemnation affecting Tenant, Tenant shall
have the right to make a claim against the condemnor for moving expenses and
business dislocation damages to the extent that such claim does not reduce the
sums otherwise payable by the condemnor to Landlord. Except as aforesaid and
except as set forth in (d) below, Tenant hereby assigns all claims against the
condemnor to Landlord.

     (d) Temporary Taking. No temporary taking of the Premises shall terminate
this lease or give Tenant any right to any rental abatement.  Such a temporary
taking will be treated as if Tenant had sublet the Premises to the condemnor and
had assigned the proceeds of the subletting to Landlord to be applied on account
of Tenant's obligations hereunder. Any award for such a temporary taking during
the Term shall be applied first, to Landlord's costs of collection and, second,
on account of sums owing by Tenant hereunder, and if such amounts applied on
account of sums owing by Tenant hereunder should exceed the entire amount owing
by Tenant for the remainder of the Term, the excess will be paid to Tenant.

14. Non-Abatement of Rent. Except as otherwise expressly provided as to damage
    ---------------------
by fire or other casualty in Section l2(b) and as to condemnation in Section
13(b), there shall be no abatement or reduction of the Rent for any cause
whatsoever, and this lease shall not terminate, and Tenant shall not be entitled
to surrender the Premises.

15. Indemnification of Landlord. Subject to Sections 7(c)(iii) and 16, Tenant
    ---------------------------
will protect, indemnify and hold harmless Landlord and its Agents from and
against any and all claims, actions, damages, liability and expense (including
fees of attorneys, investigators

                                       6
<PAGE>

and experts) in connection with loss of life, personal injury or damage to
property in or about the Premises or arising out of the occupancy or use of the
Premises by Tenant or its Agents or occasioned wholly or in part by any act or
omission of Tenant or its Agents, whether prior to, during or after the Term,
except to the extent such loss, injury or damage was caused by the negligence of
Landlord or its Agents. In case any action or proceeding is brought against
Landlord and/or its Agents by reason of the foregoing, Tenant, at its expense,
shall resist and defend such action or proceeding, or cause the same to be
resisted and defended by counsel (reasonably acceptable to Landlord and its
Agents) designated by the insurer whose policy covers such occurrence or by
counsel designated by Tenant and approved by Landlord and its Agents. Tenant's
obligations pursuant to this Section 15 shall survive the expiration or
termination of this lease.

16. Waiver of Claims. Landlord and Tenant each hereby waives all claims for
    ----------------
recovery against the other for any loss or damage which may be inflicted upon
the property of such party even if such loss or damage shall be brought about by
the fault or negligence of the other party or its Agents, provided, however,
that such waiver by Landlord shall not be effective with respect to any
liability of Tenant described in Sections 4(c) and 7(d)(iii).

17. Quiet Enjoyment.  Landlord covenants that Tenant, upon performing all of its
    ---------------
covenants, agreements and conditions of this lease shall have quiet and peaceful
possession of the Premises as against anyone claiming by or through Landlord,
subject, however, to the exceptions, reservations and conditions of this lease.

18.  Assignment and Subletting.
     -------------------------

(a) Limitation. Tenant shall not transfer this lease, voluntarily or by
operation of law, without the prior written consent of Landlord which shall not
be withheld unreasonably. However, Landlord's consent shall not be required in
the event of any transfer by Tenant to an affiliate of Tenant which is at least
as creditworthy as Tenant as of the date of this lease and provided Tenant
delivers to Landlord the instrument described in Section (c)(iii) below,
together with a certification of such creditworthiness by Tenant and such
affiliate. Any transfer not in conformity with this Section l8 shall be void at
the option of Landlord, and Landlord may exercise any or all of its rights under
Section 23. A consent to one transfer shall not be deemed to be a consent to any
subsequent transfer. "Transfer" shall include any sublease, assignment, license
or concession agreement, change in ownership or control of Tenant, mortgage or
hypothecation of this lease or Tenant's interest therein or in all or a portion
of the Premises.

     (b) Offer to Landlord. Tenant acknowledges that the terms of this lease,
including the Minimum Annual Rent have been based on the understanding that
Tenant physically shall occupy the Premises for the entire Term. Therefore, upon
Tenant's request to transfer all or a portion of the Premises, at the option of
Landlord, Tenant and Landlord shall execute an amendment to this lease removing
such space from the Premises. Tenant shall be relieved of any liability with
respect to such space and Landlord shall have the right to lease such space to
any party, including Tenant's proposed transferee.

     (c) Conditions. Notwithstanding the above, the following shall apply to any
transfer, with or without Landlord's consent

          (i) As of the date of any transfer, Tenant shall not be in default
     under this lease nor shall any act or omission have occurred which would
     constitute a default with the giving of notice and/or the passage of time.

          (ii) No transfer shall relieve Tenant of its obligation to pay the
     Rent and to perform all its other obligations hereunder.  The acceptance of
     Rent by Landlord from any person shall not be deemed to be a waiver by
     Landlord of any provision of this lease or to be a consent to any transfer.

          (iii) Each transfer shall be by a written instrument in form and
     substance satisfactory to Landlord which shall (A) include an assumption of
     liability by any transferee of all Tenant's obligations and the
     transferee's ratification of and agreement to be bound by all the
     provisions of this lease, (B) afford Landlord the right of direct action
     against the transferee pursuant to the same remedies as are available to
     Landlord against Tenant and (C) be executed by Tenant and the transferee.

          (iv) Tenant shall pay, within 10 days of receipt of an invoice which
     shall be no less than $250, Landlord's reasonable attorneys' fees and costs
     in connection with the review, processing and documentation of any transfer
     for which Landlord's consent is requested.

19.  Subordination; Mortgagee's Rights.
     ---------------------------------

     (a) This lease shall be subordinate to any first mortgage or other primary
encumbrance now or hereafter affecting the Premises.  Although the subordination
is self-operative, within 10 days after written request, Tenant shall execute
and deliver any further instruments confirming such subordination of this lease
and any further instruments of attornment that may be desired by any such
mortgagee or Landlord.  However, any mortgagee may at any time subordinate its
mortgage to this lease, without Tenant's consent,

                                       7
<PAGE>

by giving written notice to Tenant, and thereupon this lease shall be deemed
prior to such mortgage without regard to their respective dates of execution and
delivery; provided however, that such subordination shall not affect any
mortgagee's rights to condemnation awards, casualty insurance proceeds,
intervening liens or any right which shall arise between the recording of such
mortgage and the execution of this lease.

     (b) It is understood and agreed that any mortgagee shall not be liable to
Tenant for any funds paid by Tenant to Landlord unless such funds actually have
been transferred to such mortgagee by Landlord

     (c) Notwithstanding the provisions of Sections 12 and 13 above, Landlord's
obligation to restore the Premises after a casualty or condemnation shall be
subject to the consent and prior rights of Landlord's first mortgagee.

20. Recording; Tenant's Certificate. Tenant shall not record this lease or a
    -------------------------------
memorandum thereof without Landlord's prior written consent. Within 10 days
after Landlord's written request from time to time:

     (a) Tenant shall execute, acknowledge and deliver to Landlord a written
statement certifying the Commencement Date and Expiration Date of this lease,
that this lease is in full force and effect and has not been modified and
otherwise as set forth in the form of estoppel certificate attached as Exhibit
"E" or with such modifications as may be necessary to reflect accurately the
stated facts and/or such other certifications as may be requested by a mortgagee
or purchaser. Tenant understands that its failure to execute such documents may
cause Landlord serious financial damage by causing the failure of a financing or
sale transaction.

     (b) Tenant shall furnish to Landlord, Landlord's mortgagee, prospective
mortgagee or purchaser reasonably requested financial information.

21.  Surrender; Abandoned Property.
     -----------------------------

     (a) Subject to the terms of Sections 9(b), 12(a) and 13(b), at the
expiration or termination of this lease, Tenant promptly shall yield up in the
same condition, order and repair in which they are required to be kept
throughout the Term, the Premises and all improvements thereto, and all fixtures
and equipment servicing the Building, ordinary wear and tear excepted.

     (b) Upon or prior to the expiration or termination of this lease, Tenant
shall remove any personal property from the Property. Any personal property
remaining thereafter shall be deemed conclusively to have been abandoned, and
Landlord, at Tenant's expense, may remove, store, sell or otherwise dispose of
such property in such manner as Landlord may see fit and/or Landlord may retain
such property as its property. If any part thereof shall be sold, then Landlord
may receive and retain the proceeds of such sale and apply the same, at its
option, against the expenses of the sale, the cost of moving and storage and any
Rent due under this lease.

     (c) If Tenant, or any person claiming through Tenant, shall continue to
occupy the Premises after the expiration or termination of this lease or any
renewal thereof, such occupancy shall be deemed to be under a month-to-month
tenancy under the same terms and conditions set forth in this lease, except that
the monthly installment of the Minimum Annual Rent during such continued
occupancy shall be double the amount applicable to the last month of the Term.
Anything to the contrary notwithstanding, any holding over by Tenant without
Landlord's prior written consent shall constitute a default hereunder and shall
be subject to all the remedies available to Landlord.

22. Curing Tenant's Defaults. If Tenant shall be in default in the performance
    ------------------------
of any of its obligations hereunder, Landlord, without any obligation to do so,
in addition to any other rights it may have in law or equity, may elect to cure
such default on behalf of Tenant after written notice (except in the case of
emergency) to Tenant. Tenant shall reimburse Landlord upon demand for any sums
paid or costs incurred by Landlord in curing such default, including interest
thereon from the respective dates of Landlord's incurring such costs, which sums
and costs together with interest shall be deemed additional rent.

23.  Defaults - Remedies.
     -------------------

     (a)  Defaults. It shall be an event of default

          (i) If Tenant does not pay in full when due any and all Rent;

          (ii) If Tenant fails to observe and perform or otherwise breaches any
     other provision of this lease;

                                       8
<PAGE>

          (iii) If Tenant abandons the Premises, which shall be conclusively
     presumed if the Premises remain unoccupied for more than 10 consecutive
     days, or removes or attempts to remove Tenant's goods or property other
     than in the ordinary course of business, or

          (iv) If Tenant becomes insolvent or bankrupt in any sense or makes a
     general assignment for the benefit of creditors or offers a settlement to
     creditors, or if a petition in bankruptcy or for reorganization or for an
     arrangement with creditors under any federal or state law is filed by or
     against Tenant, or a bill in equity or other proceeding for the appointment
     of a receiver for any of Tenant's assets is commenced, or if any of the
     real or personal property of Tenant shall be levied upon, provided
     however, that any proceeding brought by anyone other than Landlord or
     Tenant under any bankruptcy, insolvency, receivership or similar law
     shall not constitute a default until such proceeding has continued unstayed
     for more than 60 consecutive days.

     (b) Remedies. Then, and in any such event, Landlord shall have the
following rights:

          (i) To charge a late payment fee equal to the greater of $100 or 5% of
     any amount owed to Landlord pursuant to this lease which is not paid within
     5 days after the due date.

          (ii) To enter and repossess the Premises, by breaking open locked
     doors if necessary, and remove all persons and all or any property
     therefrom, by action at law or otherwise, without being liable for
     prosecution or damages therefor, and Landlord may, at Landlord's option,
     make alterations and repairs in order to relet the Premises and relet all
     or any part(s) of the Premises for Tenant's account. Tenant agrees to pay
     to Landlord on demand any deficiency that may arise by reason of such
     reletting. In the event of reletting without termination of this lease,
     Landlord may at any time thereafter elect to terminate this lease for such
     previous breach.

          (iii) To accelerate the whole or any part of the Rent for the balance
     of the Term, and declare the same to be immediately due and payable.

          (iv) To terminate this lease and the Term without any right on the
     part of Tenant to save the forfeiture by payment of any sum due or by other
     performance of any condition, term or covenant broken.

     (c) Grace Period. Notwithstanding anything hereinabove stated, neither
party will exercise any available right because of any default of the other,
except those remedies contained in subsection (b)(i) of this Section, unless
such party shall have first given 10 days written notice thereof to the
defaulting party, and the defaulting party shall have failed to cure the default
within such period, provided, however, that:

          (i) No such notice shall be required if Tenant fails to comply with
     the provisions of Sections 10 or 20(a), in the case of emergency as set
     forth in Section 22 or in the event of any default enumerated in
     subsections (a)(iii) and (iv) of this Section.

          (ii) Landlord shall not be required to give such 10 days notice more
     than 2 times during any 12 month period.

          (iii) If the default consists of something other than the failure to
     pay money which cannot reasonably be cured within 10 days, neither party
     will exercise any right if the defaulting party begins to cure the default
     within the 10 days and continues actively and diligently in good faith to
     completely cure said default.

          (iv) Tenant agrees that any notice given by Landlord pursuant to this
     Section which is served in compliance with Section [ILLEGIBLE] shall be
     adequate notice for the purpose of Landlord's exercise of any available
     remedies.

     (d) Non-Waiver: Non-Exclusive. No waiver by Landlord of any breach by
Tenant shall be a waiver of any subsequent breach, nor shall any forbearance by
Landlord to seek a remedy for any breach by Tenant be a waiver by Landlord of
any rights and remedies with respect to such or any subsequent breach. Efforts
by Landlord to mitigate the damages caused by Tenant's default shall not
constitute a waiver of Landlords right to recover damages hereunder. No right
or remedy herein conferred upon or reserved to Landlord is intended to be
exclusive of any other right or remedy provided herein or by law, but each shall
be cumulative and in addition to every other right or remedy given herein or now
or hereafter existing at law or in equity. No payment by Tenant or receipt or
acceptance by Landlord of a lesser amount than the total amount due Landlord
under this lease shall be deemed to be other than on account, nor shall any
endorsement or statement on any check or payment be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of Rent due, or Landlord's right to
pursue any other available remedy.

                                       9
<PAGE>

     (e) Cost and Attorneys' Fees. If either party commences an action against
the other party arising out of or in connection with this lease, the prevailing
party shall be entitled to have and recover from the losing party attorneys'
fees, costs of suit, investigation expenses and discovery costs, including costs
of appeal.

24.  Representations of Tenant. Tenant represents to Landlord and agrees that:
     -------------------------

     (a) The word "Tenant" as used herein includes the Tenant named above as
well as its successors and assigns, each of which shall be under the same
obligations and liabilities and each of which shall have the same rights,
privileges and powers as it would have possessed had it originally signed this
lease as Tenant. Each and every of the persons named above as Tenant shall be
bound jointly and severally by the terms, covenants and agreements contained
herein. However, no such rights, privileges or powers shall inure to the benefit
of any assignee of Tenant immediate or remote, unless Tenant has complied with
the terms of Section 18 and the assignment to such assignee is permitted or has
been approved in writing by Landlord. Any notice required or permitted by the
terms of this lease may be given by or to any one of the persons named above as
Tenant, and shall have the same force and effect as if given by or to all
thereof.

     (b) If Tenant is a corporation, partnership or any other form of business
association or entity. Tenant is duly formed and in good standing, and has full
corporate or partnership power and authority, as the case may be, to enter into
this lease and has taken all corporate or partnership action, as the case may
be, necessary to carry out the transaction contemplated herein, so that when
executed, this lease constitutes a valid and binding obligation enforceable in
accordance with its terms. Tenant shall provide Landlord with corporate
resolutions or other proof in a form acceptable to Landlord, authorizing the
execution of this lease at the time of such execution.

25. Liability of Landlord. The word "Landlord" as used herein includes the
    ---------------------
Landlord named above as well as its successors and assigns, each of which shall
have the same rights, remedies, powers, authorities and privileges as it would
have had it originally signed this lease as Landlord. Any such person or entity,
whether or not named herein, shall have no liability hereunder after it ceases
to hold title to the Premises except for obligations already accrued (and, as to
any unapplied portion of Tenant's Security Deposit, Landlord shall be relieved
of all liability therefor upon transfer of such portion to its successor in
interest) and Tenant shall look solely to Landlord's successor in interest for
the performance of the covenants and obligations of the Landlord hereunder which
thereafter shall accrue. Neither Landlord nor any principal of Landlord nor any
owner of the Property, whether disclosed or undisclosed, shall have any personal
liability with respect to any of the provisions of this lease or the Premises,
and if Landlord is in breach or default with respect to Landlord's obligations
under this lease or otherwise, Tenant shall look solely to the equity of
Landlord in the Property for the satisfaction of Tenant's claims.
Notwithstanding the foregoing, no mortgagee or ground lessor succeeding to the
interest of Landlord hereunder (either in terms of ownership or possessory
rights) shall be (a) liable for any previous act or omission of a prior
landlord, (b) subject to any rental offsets or defenses against a prior landlord
or (c) bound by any amendment of this lease made without its written consent, or
by payment by Tenant of Minimum Annual Rent in advance in excess of one monthly
installment.

26.  Interpretation; Definitions.
     ---------------------------

     (a) Captions. The captions in this lease are for convenience only and are
not a part of this lease and do not in any way define, limit, describe or
amplify the terms and provisions of this lease or the scope or intent thereof.

     (b) Entire Agreement. This lease represents the entire agreement between
the parties hereto and there are no collateral or oral agreements or
understandings between Landlord and Tenant with respect to the Premises or the
Property. No rights, easements or licenses are acquired in the Property or any
land adjacent to the Property by Tenant by implication or otherwise except as
expressly set forth in the provisions of this lease. This lease shall not be
modified in any manner except by an instrument in writing executed by the
parties. The masculine (or neuter) pronoun and the singular number shall include
the masculine, feminine and neuter genders and the singular and plural number.
The word "including" followed by any specific item(s) is deemed to refer to
examples rather than to be words of limitation. Both parties having participated
fully and equally in the negotiation and preparation of this lease, this lease
shall not be more strictly construed, nor any ambiguities in this lease
resolved, against either Landlord or Tenant.

     (c) Covenants. Each covenant, agreement, obligation, term, condition or
other provision herein contained shall be deemed and construed as a separate and
independent covenant of the party bound by, undertaking or making the same, not
dependent on any other provision of this lease unless otherwise expressly
provided. All of the terms and conditions set forth in this lease shall apply
throughout the Term unless otherwise expressly set forth herein.

     (d) Interest.  Wherever interest is required to be paid hereunder, such
interest shall be at the highest rate permitted under law but not in excess of
15% per annum.

                                       10
<PAGE>

     (e) Severability; Governing Law.  If any of this lease shall be declared
unenforceable in any respect, such unenforceabilty shall not affect any other
provision of this lease, and each such provision shall be deemed to be modified,
if possible, in such a manner as to render it enforceable and to preserve to the
extent possible the intent of the parties as set forth herein. This lease shall
be construed and enforced in accordance with the laws of the state in which the
Property is located.

     (f) "Mortgage and "Mortgagee" The word "mortgage" as used herein Includes
any lien or encumbrance on the Premises or the Property or on any party of or
interest in or appurtenance to any of the foregoing, Including without
limitation ground rent or ground lease if Landlord's interest is or becomes a
leasehold estate. The word "mortgagee" as used herein Includes the holder of any
mortgage, Including any ground lessor if Landlord's interest is or becomes a
leasehold estate. Wherever any right is given to a mortgage, that right may be
exercised on behalf of such mortgagee by any representative or servicing agent
of such mortgagee.

     (g) "Person" The word "person" is used herein to Include a natural person,
partnership, a corporation, an association and any other form of business
association or entity.

27. Notices. Any notice or other communications under this lease shall be in
    -------
writing and addressed to Landlord or Tenant at their respective addresses
specified at the beginning of this lease, except that after the Commencement
Date Tenant's address shall be at the Premises, (or to such other address as
either may designate by notice to the other) with a copy to any mortgagee or
other party designated by Landlord. Each notice or other communication shall be
deemed given if sent by prepaid overnight delivery service or by certified mail,
return receipt requested, postage prepaid or in any other manner, with delivery
in any case evidenced by a receipt, and shall be deemed received on the day of
actual receipt by the intended recipient or on the business day delivery is
refused. The giving of notice by Landlord's attorneys, representatives and
agents under this Section shall be deemed to be the acts of Landlord; however,
the foregoing provisions governing the date on which a notice deemed to have
been received shall mean and refer to the date on which a party to this lease,
and not its counsel or other recipient to which a copy of the notice may be
sent, is deemed to have received the notice.

28.  Security Deposit. At the time of signing this lease, Tenant shall deposit
     ----------------
with Landlord the Security Deposit to be retained by Landlord as cash security
for the faithful performance and observance by Tenant of the provisions of this
lease. Tenant shall not be entitled to any interest whatever on the Security
Deposit. Landlord shall have the right to commingle the Security Deposit with
its other funds. Landlord may use the whole or any part of the Security Deposit
for the payment of any amount as to which Tenant is in default thereunder or to
compensate Landlord for any loss or damage it may suffer by reason of Tenant's
default under this lease. If Landlord uses all or any portion of the Security
Deposit as herein provided, within 10 days after written demand therefor, Tenant
shall pay Landlord cash in amount equal to that portion of the Security Deposit
used by Landlord. If Tenant shall comply fully and faithfully with all the
provisions of this lease, the Security Deposit shall be returned to Tenant after
the Expiration Date and surrender of the Premises to Landlord.

     IN WITNESS WHEREOF, and in consideration of the mutual entry into this
lease and for other good and valuable consideration, and intending to be legally
bound, Landlord and Tenant have executed this lease.

29.  PA Additional Remedies.
     ----------------------

     (a) When this lease and the Term or any extension thereof shall have been
terminated on account of any default by Tenant, which remains uncured after the
expiration of any applicable notice and/or cure period, or when the Term or any
extension thereof shall have expired, Tenant hereby authorizes any attorney of
any court of record of the Commonwealth of Pennsylvania to appear for Tenant and
for anyone claiming by, through or under Tenant and to confess judgment against
all such parties, and in favor of Landlord, in ejectment and for the recovery of
possession of the Premises, for which this lease or a true and correct copy
hereof shall be good and sufficient warrant. AFTER THE ENTRY OF ANY SUCH
JUDGMENT A WRIT OF POSSESSION MAY BE ISSUED THEREON WITHOUT FURTHER NOTICE TO
TENANT AND WITHOUT A HEARING. If for any reason after such action shall have
been commenced it shall be determined and possession of the Premises remain in
or be restored to Tenant. Landlord shall have the right for the same default and
upon any subsequent default(s) or upon the termination of this lease or Tenant's
right of possession as herein set forth, to again confess judgment as herein
provided, for which this lease or a true and correct copy hereof shall be good
and sufficient warrant.

     (b) The warrant to confess judgment set forth above shall continue in full
force and effect and be unaffected by amendments to this lease or other
agreements between Landlord and Tenant even if any such amendments or other
agreements increase Tenant's obligations or expand the size of the Premises.
Tenant waives any procedural errors in connection with the entry of any such
judgment or in the issuance of any one or more writs of possession or execution
or garnishment thereon.

     (c) EXCEPT AS OTHERWISE SET FORTH IN THIS LEASE, TENANT KNOWINGLY AND
EXPRESSLY WAIVES ANY RIGHT, INCLUDING, WITHOUT LIMITATION, UNDER ANY APPLICABLE
STATUTE, WHICH TENANT MAY HAVE TO RECEIVE A NOTICE TO QUIT PRIOR TO LANDLORD
COMMENCING AN ACTION FOR REPOSSESSION OF THE PREMISES.

                                                              Initials on behalf

30.  Base Building Improvements; Tenant Improvements.
     -----------------------------------------------

     (a) Defined Terms. The terms set forth in the Summary of Terms and Certain
         -------------
Definitions (on page 1 hereof) notwithstanding, the date set forth in Section
1(c)(i) is defined as the "COMPLETION DATE" and the "COMMENCEMENT DATE" is the
date set forth in subsection (i) below.

     (b) Base Building Improvements. Landlord shall construct and complete, at
         --------------------------
its sole cost and expense, improvements to the Building and the Property set
forth on the Scope of Work attached hereto as Exhibit "F" (the "Base Building
Improvements"). Landlord shall perform the Base Building Improvements in a good
and workmanlike manner pursuant to duly authorized and issued permits and
approvals and the Base Building Improvements shall comply at the time of
completion with all Laws and Requirements of the governmental authorities having
jurisdiction which are applicable to such construction.

     (c) Tenant Improvements. Landlord shall, at its sole cost and expense,
         -------------------
subject to reimbursement as set forth in subsection (g) below, construct and
complete the Premises ("Landlord's Work") in accordance with the plans attached
hereto as Exhibit "G" (herein called the "Plans") and specifications attached
hereto as Exhibit "H" (herein called the "Specifications"). Landlord's Work
shall be performed in a good and workmanlike manner pursuant to duly authorized
and issued permits and approvals and shall comply at the time of completion with
all law's and requirements of the governmental authorities having jurisdiction
which are applicable to such construction.

     (d) Tenant Changes in Plans and Specifications. Tenant shall have the
         ------------------------------------------
right, from time to time after the approval of the Plans and the Specifications,
to make changes in and to improvements shown thereon, provided, however, that
Landlord shall have the right to withhold its approval of changes requested by
Tenant which, in Landlord's reasonable judgment, (i) conflict with applicable
provisions of law or any covenants or restrictions applicable to the Property,
or (ii) would render the Premises materially more difficult to relet upon
termination of this lease, or (iii) require structural changes. Any such changes
shall be confirmed by written change order signed by Landlord and Tenant as set
forth in subsection (i) below, which shall confirm any delay caused by such
changes. Any delay in substantial completion of Landlord's Work as a result of
any such changes shall constitute a Tenant Delay (as hereinafter defined).

     (e) Landlord Changes in Plans and Specifications. Landlord shall have the
         --------------------------------------------
right from time to time, after the approval of the Plans and the Specifications,
to make reasonable and non-material changes in and to the same in each instance,
to the extent that the same shall be reasonably necessary:

          (i) in connection with Landlord's construction of the Premises,
     including without limitation, replacing then unavailable specified
     materials with materials of equivalent or better quality, provided,
     however, that Landlord shall make no changes to the finishes of the
     Premises or changes which would increase the Cost of the Construction (as
     hereinafter defined) or affect the operation of the Premises for the Use
     without the prior written consent of Tenant; and/or

                                       2
<PAGE>

          (ii) in order to cause Landlord's Work to comply with any applicable
     requirements of public authorities and/or requirements of insurance bodies.

Any changes made by Landlord pursuant to this subsection shall not increase the
Cost of Construction nor deviate from the intended result of the Plans and
Specifications.

     (f) Construction. All construction shall be commenced promptly by Landlord
         ------------
and shall be substantially completed and ready for use and occupancy by Tenant
on the Completion Date. The time for substantial completion of the Premises
shall be extended for additional periods of time equal to the time actually lost
by Landlord or Landlord's contractors, subcontractors or suppliers due to Change
Orders, Tenant Delays (as hereinafter defined), strikes or other labor troubles,
governmental restrictions and limitations, scarcity, unavailability or delays in
obtaining fuel, labor or materials, war or other national emergency, accidents,
floods, defective materials, fire damage or other casualties, adverse weather
conditions, or any cause similar or dissimilar to the foregoing beyond the
reasonable control of Landlord or Landlord's contractors, subcontractors or
suppliers (collectively "Excusable Delays"), provided that in each instance
Landlord shall have notified Tenant promptly upon learning of such occurrence or
the reasonable likelihood thereof and the length of the anticipated delay.

     (g) Cost of Construction. As used herein, the term "Cost of Construction"
         --------------------
shall mean and refer to the following costs, expenses and fees incurred by or on
behalf of Landlord in connection with Landlord's Work: (i) architectural,
engineering and design costs, (ii) the cost charged to Landlord by Landlord's
general contractor and all subcontractors for performing such construction, and
(iii) the actual cost to Landlord of performing directly any portion of such
construction. Landlord has heretofore competitively bid Landlord's Work to three
general contractors and, with Tenant's consent, has selected Shields
Construction as Landlord's general contractor.

     When Landlord's Work has been substantially completed, the Cost of
Construction will be totaled. If such total (the "Total") exceeds an allowance
(the "Allowance") of $25.00 per rentable square foot for the first 45,000 square
feet of the Premises plus $10.00 per rentable square foot for the remaining
13,863 square feet of the Premises for a total Allowance of $1,263,630 ("Excess
Cost"), the amount of the Excess Cost shall be due and payable by Tenant to
Landlord within thirty (30) days after Tenant's receipt of Landlord's
computation of the Total, together with reasonable supporting backup
documentation, and a bill for the Excess Cost. Such payment shall be due as
Additional Rent, hereunder.

     If the Total is less than the Allowance (a "Cost Decrease"), Tenant's
Minimum Annual Rent obligation throughout the Term shall decrease by $0.1619 per
year for each $1.00 of the Cost Decrease, to be apportioned for amounts of such
Cost Decrease which are less than $1.00.

     In no event shall the Total exceed $1,435,409 unless due to changes
pursuant to subsections 30(d), 30(e) or 30(i)(ii).

     (h) Acceptance of Premises. Section 3 of the Lease is deleted and restated
         ----------------------
as follows:

                                        3
<PAGE>

     "Landlord represents to Tenant that the Property is zoned BC (Business
Campus District). Tenant has been given the opportunity to examine Township's
Zoning Code, and has satisfied itself that such Code will permit the use of the
Property for the conducting of Tenant's business thereon. Tenant's acceptance of
occupancy of the Premises shall, subject to such obligations as are assumed by
Landlord hereunder, and subject to Landlord's warranty obligations as
hereinafter described, constitute Tenant's acceptance of the work which Landlord
is required to perform pursuant to subsection 30(c), and any schedule or exhibit
in this lease, excepting only items listed on the Punch List (as hereinafter
defined). Tenant and its agents shall have the right, at Tenant's own risk,
expense, and responsibility, at all reasonable times prior to the Commencement
Date, upon reasonable prior notice to Landlord, to enter the Premises for the
purpose of taking measurements and installing its furnishings and equipment;
provided that Tenant does not interfere with or delay the work to be performed
by Landlord and Tenant uses contractors and workers compatible with the
contractors and workers engaged by Landlord.

     At or immediately prior to the time Tenant takes occupancy of the Premises,
a representative of Landlord and a representative of Tenant will perform a
walk-through inspection of the Premises and will prepare a punch list, if one is
required, of any items remaining to be completed, furnished, repaired, or
replaced ("Punch List"). Such Punch List will be signed by a representative of
Landlord and a representative of Tenant. Landlord agrees to cause all items
listed on the Punch List to be performed within thirty (30) days or such longer
period as shall be reasonably required in order to complete such items with
reasonable diligence."

          (i) Term. Section 5 of the Lease is deleted and restated as follows:
              ----

          "(i) The Term of this Lease shall commence on the earlier of (A) the
     date of substantial completion (as hereinafter defined) of the improvements
     to be constructed by Landlord under subsection 30(c), or (B) the date
     Tenant first uses the Premises for the conduct of Tenant's business (the
     "COMMENCEMENT DATE") and shall end at 11:59 P.M. on the last day of the
     Term (the "EXPIRATION DATE"), without the necessity for notice from either
     party, unless extended pursuant to the terms of this Lease, or sooner
     terminated in accordance with the terms hereof. Landlord shall confirm the
     Commencement Date and the Expiration Date by executing and delivering to
     Tenant a Lease Commencement Certificate in the form attached as Exhibit
     "B". In the event Tenant disagrees with the Commencement Date and the
     Expiration Date set forth in the Lease Commencement Certificate, Tenant
     shall notify Landlord in writing of its objection thereto, setting forth
     the basis for Tenant's objection. If no written objection to the Lease
     Commencement Certificate is received by Landlord within 10 days after
     Tenant's receipt of the Lease Commencement Certificate, the Commencement
     Date and the Expiration Date set forth in the Lease Commencement
     Certificate shall be conclusively deemed to be accurate.

     If and to the extent that the date of substantial completion of the
Premises is delayed as a result of a Tenant Delay (as hereinafter defined), the
Term of this lease and the Commencement Date (for all purposes other than
Tenant's right to occupy the Premises) and Tenant's obligation to pay rent for
the Premises shall commence as of the date the Premises would have been
substantially complete but for such Tenant Delays.

          (ii) As used in this lease, the term "Tenant Delay" shall mean any:

                                       4
<PAGE>

               (A) If a Change Order is signed by both Landlord and Tenant, the
          Change Delay stated therein; or if a request for a Change Order is not
          signed by both Landlord and Tenant, any actual delay resulting from
          Landlord's evaluation of Tenant's Change Order request, and any actual
          delay caused by a work stoppage required in connection with a review
          of Tenant's request for a Change Order; provided that in no case where
          a Change Order is not signed shall Tenant be charged with any such
          delay unless Landlord has given Tenant prior notice that Landlord's
          review of Tenant's Change Order request will cause such delay; and

               (B) Actual delays caused by any of Tenant's installation or
          construction work or Tenant's physical conduct at the Premises
          actually interfering with the progress of Landlord's Work.

     The Premises will be deemed substantially complete when Landlord's
independent architect shall certify to Tenant that (i) all work which Landlord
is required to perform pursuant to subsection 30(c) has been satisfactorily
completed (subject only to completion of items set forth on the Punch List),
(ii) the HVAC, fire protection, electrical systems and all other building
systems shall be in proper working order and functioning (subject to adjustment
for seasonal conditions) in accordance with design standards set forth herein,
the exhibits hereto or the Plans and Specifications, (iii) safe access to and
egress from all parking areas shall be provided, and (iv) all requisite township
and state certificates of occupancy shall have been delivered by Landlord to
Tenant, and Tenant shall be able to take occupancy of the Premises and fully use
and enjoy the Premises for the conduct of its business thereon. The foregoing
notwithstanding, the Premises shall not be deemed other than substantially
complete by reason of(a) a punch list, if any, of minor items remaining to be
completed, furnished, repaired, or replaced, (b) the issuance of only a
temporary certificate of occupancy by the township, provided that all conditions
to the issuance of all final certificates (or other permits) required for
Tenant's lawful occupancy shall be issued in the ordinary course without the
satisfaction of any further conditions (including the payment of money or the
performance of any work), and provided, further, that if any further conditions
remain to be satisfied, then Landlord shall follow-up with all due dispatch to
cause the issuance of final certificates of occupancy without expense to Tenant
or any interference with Tenant's use and enjoyment of the Premises. In
addition, the Premises shall not be deemed other than substantially complete by
reason of Landlord's failure at the time of substantial completion to deliver a
final certificate of occupancy from the Commonwealth of Pennsylvania Department
of Labor and Industry, provided that Tenant shall be permitted to assume lawful
occupancy of the Premises pending the issuance thereof, and provided, further,
that if any further conditions remain to be satisfied for the issuance thereof
then anything in this Lease contained to the contrary notwithstanding
(including, without limitation, the limited period of Landlord's warranties
herein otherwise expressed), Landlord shall proceed, at its sole cost and
expense and with all due dispatch, to cause the issuance of the final
certificate of occupancy from the Department of Labor and Industry without
expense to Tenant and without any interference with Tenant's use and enjoyment
of the Premises, without regard to how long it shall take to cause such
certificate to be issued. Landlord shall indemnify, defend and save and hold
harmless Tenant of, from and against any and all loss, cost, expense, damage or
liability (including reasonable attorneys' fees and costs) sustained or incurred
by reason of any determination by the Department of Labor and Industry or by any
other agency or authority that Tenant's use and occupancy of the Premises prior
to issuance of the said final certificate of occupancy was not lawful."

<PAGE>

     j) Notwithstanding anything to the contrary contained in this lease:

          (i) in the event Landlord's Work has not been substantially completed
     (as such term is defined in this lease) on or before September 1, 1999, as
     such date shall be extended for Excusable Delays, Tenant shall receive one
     (1) day's minimum rent for each day thereafter until Landlord's Work has
     been substantially completed.

          (ii) in the event Landlord's Work has not been substantially completed
     (as such term is defined in this lease) on or before December 31, 1999, as
     such date shall be extended for Tenant Delays (but not for Excusable
     Delays) (the "Termination Right Date"), Tenant shall have the right to
     terminate this lease upon 30 days' written notice to Landlord given within
     10 business days after the Termination Right Date, provided, however, if
     Landlord substantially completes (as such term is defined in this lease)
     Landlord's Work within such 30 day period, Tenant's notice of termination
     shall be null and void and of no further force or effect.

31.  Multiple Option to Extend Term
     ------------------------------

     Provided that both at the time of the exercise of this option (the
"Exercise") and at the commencement of the additional period for which the
option is being exercised (the "Additional Term Commencement"), there exists no
uncured Event of Default by Tenant under this lease and provided that Tenant (or
any assignee of Tenant approved by Landlord or otherwise permitted under this
lease without Landlord's consent) is the sole occupant of the Premises (except
for the occupancy of others pursuant to one or more subleases, provided that
such subleases, in the aggregate, relate to less than all of the Premises and
also, with exercise of all options available to the sublandlord and sublessee,
will not extend to the Expiration Date as it is then defined), Tenant shall have
the right and option to extend the Term for 2 additional periods of 60 months
each, exercisable by giving Landlord prior written notice, at least 9 months in
advance of the then Expiration Date, of Tenant's election to extend the Term; it
being agreed that time is of the essence and that this option is personal to
Tenant and nontransferable to any assignee (other than any assignee approved by
Landlord in writing or otherwise permitted under this lease without Landlord's
consent) or sublessee (regardless of whether any such sublease was made with or
without Landlord's consent) or other party. Such extension shall be under the
same terms and conditions as provided in this lease except as follows:

     (a) The additional period shall begin on the then Expiration Date, as such
date may have been extended, and thereafter the Expiration Date shall be deemed
to be the 5th anniversary of the immediately preceding Expiration Date;

     (b) All references to the Term in this lease shall be deemed to mean the
Term as extended pursuant to this Section;

     (c) Tenant's right and option to extend the Term for 2 additional periods
as described above shall decrease by 1 additional period for each such
additional period that Tenant has extended the Term; and

     (d) The Minimum Annual Rent during each lease year of each additional
period shall be $0.35 per rentable square foot more than the Minimum Annual Rent
applicable in the immediately preceding lease year.

32. Expansion Option.  Provided Tenant is not then in default under this lease
    ----------------
beyond applicable notice and/or cure periods herein set forth, Tenant shall
have the right, at its option, to lease the space containing approximately
12,935 rentable square feet which is contiguous to the Premises and shown as
"Expansion Space" on Exhibit "A" (the "Expansion Space"), on the same terms and
conditions set forth in this lease, subject to the following:

     (a) Tenant acknowledges that the Expansion Space is or will be leased to a
tenant (the "Expansion Space Tenant") pursuant to a lease (the "Expansion Space
Lease") which expires on or about April 30, 2000, subject to the Expansion Space
Tenant's right to extend the term of the Expansion Space Lease for an additional
6 month period.

     (b) Promptly after the date on which the Expansion Space Tenant is required
to exercise its option to extend for 6 months (which is 120 days prior to the
initial expiration date of the Expansion Space Lease), Landlord shall notify
Tenant in writing ("Landlord's Notice") as to whether or not the Expansion Space
Tenant has exercised such option. In the event the Expansion Space Tenant has
not exercised such option, Tenant shall notify Landlord in writing ("Tenant's
Notice") on or before 10 business days after receipt of Landlord's Notice, such
time to be of the essence, whether it desires to lease the Expansion Space. In
the event the Expansion Space Tenant has exercised such option, Tenant shall, if
it desires to lease the Expansion Space, give Tenant's Notice on or before April
30, 2000, such time to be of the essence. If Tenant timely notifies Landlord
that it desires to lease the Expansion Space, Landlord and Tenant shall promptly
execute an amendment to this lease incorporating the Expansion Space in the
Premises, increasing the Minimum Annual Rent and Tenant's Proportionate Share to
reflect the increased area of the Premises and making such other changes to the
lease as may be required thereby.

     (c) Landlord shall complete the Expansion Space in accordance with plans
and specifications therefor consistent with the Plans and Specifications.
Landlord shall deliver the Expansion Space vacant, broom clean, free of all
claims and possession by third parties and in compliance with all Laws and
Requirements. Rent with respect thereto shall not be payable until the earlier
of (i) the date Tenant first uses the Expansion Space for the conduct of
Tenant's business, or (ii) substantial completion of the Expansion Space.
Landlord shall provide an allowance of $25.00 per square foot for the Expansion
Space as set forth in Section 30(g), any excess to be paid by Tenant and any
decrease to be credited to Tenant over the remaining term of the lease. The
allowance for the Expansion Space, together with interest thereon at the rate of
10.5% per annum, shall be paid as additional minimum annual rent by Tenant over
the remaining term of the lease.

     (d) In the event Tenant fails to timely notify Landlord of its desire to
lease the Expansion Space, this Section shall automatically be null and void and
of no further force or effect.

     (e) In the event Tenant has timely notified Landlord of its desire to lease
the Expansion Space and in the event the Expansion Space Tenant fails to timely
vacate the Expansion Space, Landlord shall, at Landlord's sole cost and expense,
promptly commence and diligently pursue commercially reasonable efforts to
obtain possession of the Expansion Space and, if requested by Tenant, Landlord
shall use reasonable efforts to locate temporary space for

                                       7

Tenant in other buildings owned by Landlord in the Horsham, Pennsylvania area
which shall be leased to Tenant at market rates.

     33. Right of First Offer. If and when any portion of the Building (each,
         --------------------
individually, the "Additional Space") becomes available for rental during the
term of this Lease and provided that there then exists no event of default by
Tenant under this lease which has continued beyond applicable notice and/or cure
periods contained in this Lease, and provided that Tenant (or any assignee of
Tenant approved by Landlord or otherwise permitted under this lease without
Landlord's consent) is the sole occupant of the Premises (except for the
occupancy of others pursuant to one or more subleases approved by Landlord or
otherwise permitted under this lease without Landlord's consent, provided that
such subleases, in the aggregate, relate to less than all of the Premises and
also, with exercise of all options available to the sublandlord and sublessee,
will not extend to the Expiration Date as it is then defined), Tenant shall have
the right of first offer to lease all of the Additional Space or, should Tenant
desire to lease less than all of the Additional Space, such lesser portion
thereof as Landlord may, in its reasonable discretion, agree to, subject to the
following:

     (a) Landlord shall notify Tenant each time that the Additional Space first
becomes available for rental by any party other than the tenant then in
occupancy of the Additional Space and Tenant shall have 5 business days
following receipt of such notice within which to notify Landlord in writing that
Tenant is interested in negotiating terms for leasing such Additional Space and
to have its offer considered by Landlord prior to the leasing by Landlord of the
Additional Space to a third party. If Tenant notifies Landlord within such time
period that Tenant is so interested, then Landlord and Tenant shall have 10 days
following Landlord's receipt of such notice from Tenant within which to
negotiate mutually satisfactory terms for the leasing of the Additional Space by
Tenant and to execute an amendment to this lease incorporating such terms or a
new lease for the Additional Space. During such 5 business day and 10 day
periods, Tenant shall have the exclusive right to receive notice of the
availability of the Additional Space and to negotiate terms for the leasing
thereof and Landlord shall not solicit other offers for the Additional Space
during such time periods. Landlord and Tenant agree to negotiate terms for the
leasing of the Additional Space in good faith based on then existing market
conditions.

     (b) If Tenant does not notify Landlord within such 5 days of its interest
in leasing the Additional Space or if Tenant does not execute such amendment or
lease within such 10 days, if applicable, then this right of first offer to
lease the Additional Space will lapse and be of no further force or effect and
Landlord shall have the right to lease all or part of the Additional Space to
any other party at any time on any terms and conditions acceptable to Landlord.

     (c) This right of first offer to lease the Additional Space applies each
time the Additional Space becomes available, subject to renewal rights of any
tenant of the Additional Space.

     34. Tenant's Need to Expand. In the event Tenant notifies Landlord in
         -----------------------
writing during the Term that it requires premises containing at least
thirty-five (35%) percent more space than the Premises for the conduct of its
business, and provided Tenant is not then in default under the terms of this
Lease after the expiration of any applicable notice and/or cure periods, then at
Tenant's option, Landlord, to the extent such larger space is available in the
Building or in other

                                        8

<PAGE>

buildings owned by Landlord ("Other Buildings") which is not subject to
expansion options or other rights of tenants in the Building or the Other
Buildings, shall agree to lease same to Tenant at fair market rental rates and
other market terms existing at such time. In the event Landlord and Tenant
execute a lease for such larger space (the "New Lease"), then upon the
commencement date of the New Lease and timely delivery by Tenant of the Premises
to Landlord, vacant and in the condition required upon termination of this
lease, Landlord shall release Tenant from any further obligations under this
lease, except for those obligations set forth herein which specifically survive
termination of this lease.

     This provision is valid only for so long as Liberty Property Trust or its
affiliates own the Building.

     35. Parking. Tenant shall have the right to use, on a non-exclusive basis,
         -------
370 parking spaces. Upon any expansion by Tenant, Tenant shall have the right to
use, on a non-exclusive basis, an additional 4 parking spaces per 1,000 square
feet of rentable area of the expansion premises, but in no event shall Tenant
ever have the right to use more than 550 parking spaces.

     36. Termination of Existing Leases. Tenant currently occupies premises
         ------------------------------
(hereafter referred to individually as the "Existing Premises") located in the
buildings at Two Walnut Grove Drive, 111-195 Witmer Road and 100 Lakeside Drive,
Horsham, Pennsylvania, pursuant to those certain leases listed on Exhibit "I"
attached hereto between Landlord or Landlord's predecessor and Tenant (each of
said lease agreements, collectively, the "Existing Lease"). At such time as the
Commencement Date hereunder shall have occurred and Tenant shall have vacated an
Existing Premises leaving same in the condition required upon termination as set
forth in the Existing Lease applicable to such Existing Premises, such Existing
Lease shall terminate and be of no further force and effect; provided, however,
that (a) all covenants, obligations and indemnifications of Landlord and Tenant
as set forth in such Existing Lease (as the same pertain to the leasing of the
Existing Premises prior to the Commencement Date of this lease) shall survive
and remain in force following the Commencement Date of this Lease and shall be
paid or performed by the applicable party when due or owing, provided that
Landlord shall submit a final operating expense reconciliation to Tenant "with
respect to such Existing Lease within 90 days after the termination of such
Existing Lease, and (b) all obligations, covenants and indenmifications of
Landlord and Tenant which are stated in such Existing Lease to survive
termination thereof, shall survive.

     37. Contingency
         -----------

     (a) Landlord has entered into an agreement of sale to purchase the
Property. This lease and the obligations of the parties hereunder are contingent
upon Landlord's acquisition of title to the Property.

promptly refunded to Tenant and the parties shall thereafter have no further
liability hereunder.

     39. Additional Provisions Relating to Building and Premises. Subject to

Tenant's alteration of or installations in or upon the Property. It is further
agreed that if the restrooms of the Premises are determined, by any governmental
authority having jurisdiction, to be not in compliance with ADA requirements
existing on the Commencement Date, Landlord will, at its sole cost and expense,
perform necessary modifications thereto to make same comply with applicable ADA
requirements in effect on the Commencement Date.

     (c) It is agreed that Tenant's responsibilities pursuant to subsection 4(c)
shall be limited to Restricted Activities performed by or on behalf of Tenant.

limitation, cleanup costs, penalties, fines and reasonable counsel, engineering
and other professional or expert fees and costs) arising from any Restricted
Activities which occurred on the Premises prior to the date of this lease and
any Restricted Activities by Landlord or its Agents.

     (d) On the third (3rd) line of subsection 4(d), delete "5 days after first
learning thereof" and substitute therefor "5 business days after an officer of
Tenant first learns thereof".

     (g) The following provision is hereby added at the end of subsection
7(a)(ii):

     "Tenant shall have the right to make any payment required pursuant to this
subsection 7(a)(ii) "under protest" and, if Tenant makes payment of such sums
under protest, such payment shall not be regarded as a voluntary payment, and
there shall survive the right on the part of Tenant to institute suit for the
recovery of such sum. Notwithstanding the foregoing to the contrary, if such
suit is not commenced within six (6) months after the payment under protest has
been made, the cause of action shall be deemed wholly lost. If Tenant commences
such suit within the required time period, and it shall be adjudged that there
was no legal obligation on the part of Tenant to pay such sum or any part
thereof, Tenant shall be entitled to recover such sum or so much thereof as it
was not legally required to pay under the provisions of this Lease."

     (h) The following additional clause is added at the end of subsection

         -----------
subsection 7(b):

     For the purposes of this subsection 7(b), Tenant's Proportionate Share of a
municipal assessment (but not a real estate tax) shall only include those
installments thereof becoming due during the Term. If any assessments may be
paid in installments over a period of years, such assessments shall, for the
purposes of subsection 7(b), be deemed to be payable over the longest number of
years permitted by the assessing authority, and only the installments coming due
during the Term, together with any interest or carrying charges due, will be
included within the Impositions payable by Tenant. With regard to real estate
taxes, Landlord agrees to take advantage of opportunities to pay such taxes
during the discount period.

     Any provision of this subsection 7(b) to the contrary notwithstanding,
Tenant's obligation hereunder shall not include any franchise, estate,
succession, or inheritance



                                       13

taxes, nor any penalties imposed for late payment of any real estate tax,
assessment or other Imposition (except for penalties on taxes which Landlord has
not paid as a result of a bona fide contest or for which it has not received
payment from Tenant) and shall in no event include any real estate tax or
assessment attributable solely to a period occurring prior to the Commencement
Date.

     Provided Tenant then leases more than 75% of the Building and provided
Tenant is not then in default under this Lease beyond applicable notice and/or
cure periods, Tenant shall have the right to require Landlord, at Tenant's sole
cost and expense, to contest or appeal the real estate taxes and tax assessments
relating to the Property. In lieu thereof, Landlord may authorize Tenant to
prosecute such appeal or contest, provided that Tenant shall provide to Landlord
for its reasonable review and approval prior to filing any applications,
affidavits and like supporting documentation required in connection with such
effort, Landlord shall have reasonably approved such contest or appeal and
Tenant shall consult with Landlord as requested in connection with such process,
and if undertaken, such contest or appeal shall be prosecuted with diligence and
in good faith and at Tenant's sole cost and expense. Landlord shall reasonably
cooperate with Tenant (including signing applications, affidavits and the like,
if so requested) subject to and in accordance with the conditions set forth in
this paragraph. Tenant acknowledges and agrees that Landlord's "reasonable
review and approval", as such term is used herein, shall mean and refer to
Landlord's good faith consideration of the reasonableness of Tenant's proposed
contest or appeal, and the accuracy of information set forth in such
documentation as shall have been prepared by Tenant and submitted to Landlord
for its review.

     In no event shall impositions include fees, charges or assessments in
connection with the initial construction or development of the Property or
Landlord's redevelopment thereof, including, without limitation, development
fees, tap-in fees or other initial assessments or payments due and payable to
the local municipality or to a governmental or quasi-governmental agency or
authority in connection with the initial planning, approval or development of
the Property. The foregoing notwithstanding, Tenant acknowledges and agrees that
the Impositions for which Tenant is responsible hereunder shall include real
estate taxes which shall be levied based upon Montgomery County's assessment of
the Property as improved with the Buildings and other improvements contemplated
in this Lease.

     Upon Tenant's request, Landlord shall provide to Tenant copies of real
estate tax bills and any correspondence received by Landlord regarding real
estate taxes and assessments with respect to the Property.

     (j) In subsection 7(c)(ii), in the sixth and seventh lines thereof, the
phrase "as insured parties" is replaced with the phrase "as additional
insureds." In the seventh line thereof, after the word "Premises," add "only, as
expressly distinguished, for purposes hereof, from the balance of the Property."

     In subsection 7(c)(ii), the following amendments are hereby made to the
requirements regarding Tenant's liability insurance:

     In the ninth line of the printed form paragraph 7(c)(ii), at the end of the
printed line, after the word "issued in form," add "reasonably".



                                       14

<PAGE>

     Landlord, as an operating expense, shall keep in effect comprehensive
general public liability insurance with respect to the Property, including
contractual liability insurance, which insurance shall provide combined single
limit per occurrence coverage of not less than Two Million Dollars ($2,000,000)
for property damage and bodily injury or death to one or more persons, with
endorsements for contractual liability. The insurer shall be a responsible
insurance carrier which is authorized to issue such insurance and licensed to do
business in the Commonwealth of Pennsylvania, and which has, at all times during
the Term, a rating of not less than A VII in the most current edition of Best's
Insurance Reports. Landlord shall deliver to Tenant on or before the
Commencement Date and subsequently upon request by Tenant from time to time, but
not more often than once every twelve (12) months, current certificates of
insurance evidencing the aforesaid comprehensive general public liability
insurance coverage, the property and casualty insurance coverage required of
Landlord under Section 7(c) of the Lease, and the waiver of subrogation or other
policy provision required by subsection 7(c)(iii).

     In the event that Landlord shall request that Tenant increase its limits of
insurance as provided in Paragraph 7(c)(ii) of the Lease, Tenant agrees to do so
provided that the increased limits requested by Landlord are consistent with
limits of insurance then being required of tenants of other first class office
properties in the suburban Philadelphia office market, and provided, further,
that Landlord shall likewise increase the limits of insurance it is then
carrying to such levels as are then being required of Tenant by Landlord.

     (k) In subsection 7(d)(ii), it is agreed that the written notice required
may be given by telefacsimile transmission addressed to Landlord's property
manager. Also with regard to such subsection, it is agreed that Landlord will at
all times maintain the Common Areas (including parking areas) of the Property
consistent with the standards generally observed at other first class office
buildings in the suburban Philadelphia office market. Also with regard to such
subsection, it is agreed that Landlord will make no alterations to the Common
Areas which will result in material interference with Tenant's ability to use
the Premises for the normal operation of its business, twenty-four (24) hours
per day, seven (7) days per week, three hundred sixty-five (365) days per year.

     (l) With regard to subsection 7(d)(iii), it is agreed that the phrase
"Tenant's use, occupancy" shall be limited to the use or occupancy of the
Premises and the Property for other than normal business office use, and is not
intended to create additional responsibility on the part of Tenant for repairs
or replacements that would have been necessary solely as a result of Tenant's
use of the Premises and the Property for normal business office purposes.

     (m) Notwithstanding the provisions of subsection 7(e)(i) to the contrary,
it is agreed that Tenant may use the Premises and the Property twenty-four (24)
hours per day, seven (7) days per week, three hundred sixty-five (365) days per
year, and that the Premises will be furnished with electricity, heat, and air
conditioning for its normal use and occupancy at all times, subject only to
interruption by matters not within Landlord's reasonable control.

     (n) Subsection 7(e)(ii) is hereby deleted in its entirety and replaced with
the following:



                                       15

<PAGE>

          "(ii) If, as a result of any cause within Landlord's reasonable
     control (except for damage by fire or other casualty, which is dealt with
     elsewhere in this Lease), utility service to the Premises is interrupted
     resulting in a portion of the Premises being rendered untenantable for a
     period of in excess of three (3) consecutive business days, commencing on
     the fourth consecutive day of such untenantability, Tenant's obligations to
     pay Rent shall abate in proportion to that portion of the Premises so
     rendered untenantable. Such abatement shall continue until the day on which
     Landlord has cured the untenantability."

     43. Additional Provisions Relating to Alterations and Fixtures.
         ----------------------------------------------------------

     (a) With respect to subsection 9(a), Tenant shall have the right, without
Landlord's consent, to finance and to secure trade fixtures, furnishings,
equipment, machinery, signs and other personal property (excluding physical
alterations and leasehold improvements to the Building). If Tenant shall acquire
trade fixtures, equipment, machinery or other goods and effects subject to a
purchase money security interest, or shall lease any of the same, or if any
institutional lender provides Tenant with financing, the proceeds of which are
intended to enable Tenant to use and occupy the Premises or to operate Tenant's
business thereon, and such financing is secured in whole or in part by a lien on
or security interest in such goods, equipment, machinery or fixtures, Landlord
shall, upon request from Tenant, execute a subordination of any right it may
have to distrain upon or secure a lien against such goods, equipment, machinery
or fixtures for Tenant's failure to pay minimum rent or any additional rent or
any other event of default under the terms, covenants, conditions and provisions
of this lease, in substantially the form attached hereto as Exhibit "J".

     (b) In the first sentence of subsection 9(b), the amount "$5,000.00 in the
aggregate" is hereby replaced with the amount "$35,000.00 per lease year."

"reasonable" is inserted before the word "costs."

     (d) In subsection 9(b), Tenant shall not be required to have plans prepared
by an architect or engineer in connection with any proposed alterations or
improvements for which professionally prepared plans are not required in order
to obtain the necessary governmental permits and/or approvals. In such cases,
Landlord will accept accurately prepared plans prepared by Tenant's personnel or
contractors.

     (e) In subsection 9(b), with regard to alterations to the Premises which
require Landlord's approval, Landlord agrees that it will not unreasonably
withhold, delay or condition its approval, provided such alterations will not,
in Landlord's reasonable opinion, adversely impact the structure of the Building
or the operating systems of the Building. Otherwise, Landlord may withhold its
approval in its complete discretion.


     In the event Landlord fails to respond to a written request for approval
within 10 business days after receipt thereof, Tenant shall send Landlord a
second written request therefor which shall state that if no objection is made
by Landlord within 5 business days after receipt thereof, such request shall be
deemed approved by Landlord. If Landlord fails to respond within such 5 business
day period, Landlord shall be deemed to have approved such request.

required to obtain Landlord's approval with regard to the painting or
wallpapering of interior wall surfaces within the Premises, provided that Tenant
notifies Landlord in writing prior to performing any such work and any such
painting or wallpapering can be covered with one (1) coat of primer and one (1)
coat of white paint, without additional sealing or painting.

exhibit the Premises for the purpose of sale or mortgage or for the purpose of
leasing to a prospective tenant shall be restricted to normal business hours;

prospective mortgagee, purchaser, or tenant while on the Premises for such
purpose.

     If a casualty occurs during the last 12 months of the Term, as the same may
have been extended, Landlord will give notice to Tenant if, in Landlord's
reasonable opinion, the restoration of the damage will not be substantially
completed prior to that period of time which is 1/2 of the time interval
elapsing between the date of the casualty and the end of the Term. If Landlord
gives such notice to Tenant, and, within 10 days thereafter, Landlord does not
receive notice from Tenant that Tenant releases Landlord from any obligation to
restore the damage, Landlord may cancel this Lease unless Tenant has the right
to extend the Term for at least 3 more years and does so within 30 days after
the date of the casualty.

<PAGE>

     (d) Notwithstanding any provision of subsection 12(a) to the contrary, if
the Premises are damaged or destroyed by fire or other casualty and the
restoration of such damage has not been substantially completed on or before 365
days after it has occurred, Tenant shall have the right to terminate this Lease
effective 60 days after giving written notice of such termination to Landlord;
provided that if Landlord substantially completes the restoration within such 60
day period, Tenant's notice of termination shall be null and void.

     (e) In subsection 12(b), the last sentence is hereby deleted and the
following sentence is substituted therefor:

     "Tenant will receive an abatement of its minimum annual rent and operating
expenses to the extent and for so long as the Premises are rendered
untenantable, in whole or in part, for the normal conduct of Tenant's business
and are not, in fact, used for the conduct of Tenant's business."

add "or in the event access to the Property is taken, or in the event a material
portion of the parking area of the Property is taken and the remainder thereof
is insufficient for the reasonable operation of Tenant's business".

     (c) In the event of a partial taking, if Landlord's work of restoring of
the Premises results in a portion of the Premises being rendered untenantable,
Tenant's obligations to pay Rent shall abate in proportion to that portion of
the Premises which is so rendered untenantable. The amount of such abatement
shall be adjusted to reflect that portion of the Premises rendered so
untenantable from time-to-time.

     (d) With regard to subsection 13(c), in addition to having the right to
make a claim against a condemnor for moving expenses and business dislocation
damages, Tenant shall have the right to make a claim against a condemnor for any
alterations to the Premises made by Tenant at Tenant's expense, to the extent
that Tenant loses the value of such alterations for the balance of the Term.

about the Property occasioned wholly or in part by the negligence of Landlord or

and defend such action or proceeding, or cause the same to be resisted and

Landlord and approved by Tenant and its Agents. Landlord's obligations pursuant
to this Section shall survive the expiration or termination of this Lease.
Nothing contained in this Section 48 shall be construed to be in derogation of

Landlord's agent may have under such liability insurance policy.

     50. Additional Provisions Relating to Waiver of Claims. In Section 16, add

     (h) The first three (3) sentences of subsection 23(d) are hereby restated
in their entirety as follows:

     "No waiver by either party of a breach by the other shall be a waiver of
any subsequent breach, nor shall any forbearance by a party to seek a remedy for
any breach by the other party be a waiver by such forbearing party of any rights
and remedies with respect to such or any subsequent breach. Efforts by a party
to mitigate the damages caused by the other party's default shall not constitute
a waiver of the mitigating party's right to recover damages hereunder. No right
or remedy herein conferred upon or reserved to either party is intended to be
exclusive of any other right or remedy provided herein or by law, but each shall
be cumulative and in addition to every other right or remedy given herein or now
or hereafter existing at law or in equity."

     (i) If Landlord accelerates Tenant's obligations under this Lease pursuant
to the provisions of subsection 23(b)(iii), payment from Tenant to Landlord of
the accelerated obligations which would not have been due at the time of
payment, but for Tenant's default and the resulting acceleration, shall be
discontinued to present values as of the date of such payment using the prime
rate of interest (the "Prime Rate") as published in The Wall Street Journal (or
any successor publication thereto) on the day before the date that payment is
made, or, if The Wall Street Journal (or any successor publication thereto) is
not published on the last mentioned date, using the prime rate of interest as
published in the immediately preceding edition of The Wall Street Journal (or
any successor publication thereto). Payments by Tenant shall first be applied to
Landlord's reasonable out-of-pocket costs directly associated with Tenant's
default and Landlord's acceleration; next to late charges previously accrued and
unpaid; next to interest accrued; next to Tenant's obligation that would have
been due from Tenant as of the date of payment had acceleration not occurred;
and last to Tenant's obligations which would not have been due at the date of
payment, but for the acceleration. The definition of "Term" as used in this
Section 23(b)(iii) shall mean and include only the then current term hereof
during which the default occurs, unless prior to such default occurring, Tenant
shall have caused the Term hereof to be extended in accordance with the
provisions of this Lease.

     (j) If Tenant defaults under the terms of this Lease resulting in Landlord
recovering possession of the Premises, then Landlord agrees to use reasonable
efforts to relet the Premises in mitigation of Landlord's damages. Landlord
shall have no obligation to relet the Premises or any portion thereof in
preference to other space available for lease in the Building or in any other
building owned by Landlord or its affiliates.

     57. Landlord's Representation Regarding Authority. Landlord is a duly
         ---------------------------------------------
formed Pennsylvania limited partnership in good standing, and has full
partnership power and authority to enter into this Lease and has taken all
partnership action necessary to carry out the transaction contemplated herein,
so that when executed, this Lease constitutes a valid and binding obligation in
accordance with its terms.

     58. Additional Provisions Relating to Liability of Landlord.
         -------------------------------------------------------

     (a) The first sentence of Section 25 is hereby restated in its entirety as
follows:

          The word "Landlord" as used herein includes the Landlord named above
     as well as its successors and assigns, each of which shall be under the
     same obligations and liabilities accruing after it acquires its interest in
     the Property and each of which shall have the same rights, remedies,
     powers, authorities, and privileges as it would have had it originally
     signed this Lease as Landlord.

     (b) The following language is added at the end of the second sentence of
Section 25:

          (provided, except in the event of a successor in interest to Landlord
     which acquired its interest by reason of an execution sale or a deed in
     lieu of foreclosure, Landlord's successor in interest, in writing,
     expressly assumes this Lease and agrees to perform all obligations
     thereafter accruing hereunder.



                                       23

<PAGE>

     (c) The last clause of the third sentence is hereby amended to read "...,
Tenant shall look solely to the equity of Landlord in the Property and the
rents, issues, profits and sales proceeds therefrom for the satisfaction of
Tenant's claims".

     59. Additional Provisions Relating to Interpretation; Definitions. In
         -------------------------------------------------------------
subsection 26(d), on the second (2nd) line, change "15%" to "12%".

     60. Additional Provisions Relating to Notices.
         -----------------------------------------

     (a) The following language is hereby added at the end of the first sentence
of Section 27: "in writing upon not less than thirty (30) days' notice."

     (b) The last sentence of Section 27 is hereby restated in its entirety as
follows:

          The giving of notice by either party's attorneys, representatives, and
     agents under this Section shall be deemed to be the acts of such party;
     however, the foregoing provisions governing the date on which a notice is
     deemed to have been received shall mean and refer to the date on which a
     party to this Lease, and not its counsel or other recipient to which a copy
     of the notice may be sent, is deemed to have received the notice.

     61. Additional Provisions Relating to Security Deposit.
         --------------------------------------------------

     (a) Tenant may post and maintain the Security Deposit either in the form of
cash or in the form of a letter of credit. If the security deposit is maintained
in the form of a letter of credit, the following provisions shall apply:

          (i) Each letter of credit shall be in a form and content satisfactory
     to Landlord and shall be issued by a commercial bank acceptable to Landlord
     under the Uniform Commercial Code of Pennsylvania. The issuing bank must
     regularly maintain business offices in the Philadelphia Metropolitan Area
     of Pennsylvania, and such letter of credit must be presentable and payable
     at the counters of such bank located in such geographical area. Each letter
     of credit shall be irrevocable and shall impose no conditions upon the
     beneficiary's right to draw funds under it, other than a written statement
     by the beneficiary to the issuing bank that an Event of Default has
     occurred under the lease and remains uncured and Landlord is entitled to
     draw upon the letter of credit. The beneficiary of each of the letters of
     credit shall be Landlord, and each such letter of credit shall be
     assignable by Landlord to any entity succeeding to Landlord's ownership of
     the Premises. Landlord agrees that no funds will be drawn under any letter
     of credit unless and until an Event of Default has occurred under this
     lease and remains uncured or Tenant has failed to timely renew same as set
     forth in subsection (ii) below.

          (ii) Each letter of credit shall have an expiration date not earlier
     than 3 months after the Expiration Date (such date being the "Expiry
     Date"), or, if the expiration thereof is earlier than the Expiry Date, each
     such letter of credit shall be extended, renewed, or replaced at least 30
     days prior to its expiration so that it continuously remains in effect
     through the Expiry Date. If the Term of this lease is extended or renewed
     by any means, the Expiry Date shall be revised to be that date which is 3
     months after the end of the Term, as so extended. Notwithstanding any
     provision of this Section or Section 23 to the contrary, failure of Tenant
     to

                       FIRST AMENDMENT TO LEASE AGREEMENT
                       ----------------------------------


     THIS FIRST AMENDMENT is made this 15th day of May, 1999, by and between
LIBERTY PROPERTY LIMITED PARTNERSHIP, a Pennsylvania limited partnership
("Landlord"), and VERTICALNET, INC., a Pennsylvania corporation ("Tenant").


                                   BACKGROUND:
                                   ----------

     A. Landlord and Tenant entered into a Lease Agreement dated April 21, 1999
(the "Lease"), covering premises at 700 Dresher Road, Horsham, Pennsylvania, as
more fully described in the Lease.

     B. Landlord and Tenant desire to amend the Lease in certain respects.

     NOW, THEREFORE, the parties hereto, in consideration of the mutual promises
and covenants contained herein and in the Lease, and intending to be legally
bound hereby, agree that the Lease is amended as follows:

     1. All capitalized terms used herein and not otherwise defined herein shall
have the meanings ascribed to them in the Lease.

     2. Section 30 of the Lease is hereby deleted in its entirety and the
following is substituted therefor:

     "30. Base Building Improvements; Tenant Improvements.
          -----------------------------------------------

     (a) Defined Terms. The terms set forth in the Summary of Terms and Certain
Definitions (on page 1 hereof) notwithstanding, the date set forth in Section
l(c)(i) is defined as the "COMPLETION DATE" and the "COMMENCEMENT DATE" is the
date set forth in subsection (i) below.

     (b) Base Building Improvements. Landlord shall construct and complete, at
its sole cost and expense, improvements to the Building and the Property set
forth on the Scope of Work attached hereto as Exhibit "F" (the "Base Building
Improvements"). Landlord shall perform the Base Building Improvements in a good
and workmanlike manner pursuant to duly authorized and issued permits and
approvals and the Base Building Improvements shall comply at the time of
completion with all Laws and Requirements of the governmental authorities having
jurisdiction Which are applicable to such construction.

     (c) Tenant Improvements. Landlord shall, at its sole cost and expense,
subject to reimbursement as set forth in subsection (g) below, construct and
complete the Premises ("Landlord's Work") in accordance with the plans attached
hereto as Exhibit "G"

<PAGE>

(herein called the "Phase I Plans") and specifications attached hereto as
Exhibit "H" (herein called the "Phase I Specifications") and in accordance with
the plans to be attached hereto as Exhibit "G-1" (herein called the "Phase II
Plans") and the specifications to be attached hereto as Exhibit "H-1" (herein
called the "Phase II Specifications"). The Phase I Plans and the Phase I
Specifications cover Landlord's Work with respect to approximately 45,000 square
feet of the Premises ("Phase I"). The Phase II Plans and the Phase II
Specifications will cover the balance of the Premises ("Phase II") and will be
attached hereto upon approval thereof by Landlord and Tenant. The Phase I Plans,
the Phase I Specifications, the Phase II Plans and the Phase II Specifications
are hereinafter referred to collectively as the "Plans and Specifications").
Landlord's Work shall be performed in a good and workmanlike manner pursuant to
duly authorized and issued permits and approvals and shall comply at the time of
completion with all laws and requirements of the governmental authorities having
jurisdiction which are applicable to such construction.

     (d) Tenant Changes in Plans and Specifications. Tenant shall have the
         ------------------------------------------
right, from time to time after the approval of the Plans and the Specifications,
to make changes in and to improvements shown thereon, provided, however, that
Landlord shall have the right to withhold its approval of changes requested by
Tenant which, in Landlord's reasonable judgment, (i) conflict with applicable
provisions of law or any covenants or restrictions applicable to the Property,
or (ii) would render the Premises materially more difficult to relet upon
termination of this lease, or (iii) require structural changes. Any such changes
shall be confirmed by written change order signed by Landlord and Tenant as set
forth in subsection (i) below, which shall confirm any delay caused by such
changes. Any delay in substantial completion of Landlord's Work as a result of
any such changes shall constitute a Tenant Delay (as hereinafter defined).

     (e) Landlord Changes in Plans and Specifications. Landlord shall have the
         --------------------------------------------
right from time to time, after the approval of the Plans and the Specifications,
to make reasonable and non-material changes in and to the same in each instance,
to the extent that the same shall be reasonably necessary;

          (i) in connection with Landlord's construction of the Premises,
     including without limitation, replacing then unavailable specified
     materials with materials of equivalent or better quality, provided,
     however, that Landlord shall make no changes to the finishes of the
     Premises or changes which would increase the Cost of the Construction (as
     hereinafter defined) or affect the operation of the Premises for the Use
     without the prior written consent of Tenant; and/or

          (ii) in order to cause Landlord's Work to comply with any applicable
     requirements of public authorities and/or requirements of insurance bodies.

Any changes made by Landlord pursuant to this subsection shall not increase the
Cost of Construction nor deviate from the intended result of the Plans and
Specifications.

     (f) Construction. Construction of Phase I shall be commenced promptly by
         ------------
Landlord and Phase I shall be substantially completed and ready for use and
occupancy by Tenant on the Completion Date. Construction of Phase II shall be
commenced


                                        2

<PAGE>

promptly after approval of the Phase II Plans and the Phase II Specifications,
the bidding of Landlord's Work for Phase II to three general contractors, the
selection of Landlord's contractor, with Tenant's consent, and the issuance of
all state and local permits required therefor, and shall be substantially
completed and ready for use and occupancy by Tenant within sixty (60) days after
issuance of such permits. The Phase II Plans and the Phase II Specifications are
being prepared by Tenant's architect. Landlord and Tenant shall use reasonable
good faith efforts to finalize the Phase II Plans and the Phase II
Specifications as soon as reasonably possible after receipt of same from
Tenant's architect. Upon approval of the Phase II Plans and the Phase II
Specifications, completion of bidding of Landlord's Work and the selection of
Landlord's contractor, Landlord shall promptly apply for required permits and
shall use diligent efforts to obtain same as soon as possible. The time for
substantial completion of Phase I and Phase II shall be extended for additional
periods of time equal to the time actually lost by Landlord or Landlord's
contractors, subcontractors or suppliers due to Change Orders, Tenant Delays (as
hereinafter defined), strikes or other labor troubles, governmental restrictions
and limitations, scarcity, unavailability or delays in obtaining fuel, labor or
materials, war or other national emergency, accidents, floods, defective
materials, fire damage or other casualties, adverse weather conditions, or any
cause similar or dissimilar to the foregoing beyond the reasonable control of
Landlord or Landlord's contractors, subcontractors or suppliers (collectively
"Excusable Delays"), provided that in each instance Landlord shall have notified
Tenant promptly upon learning of such occurrence or the reasonable likelihood
thereof and the length of the anticipated delay.

     (g) Cost of Construction. As used herein, the term "Cost of Construction"
         --------------------
shall mean and refer to the following costs, expenses and fees incurred by or on
behalf of Landlord in connection with Landlord's Work: (i) architectural,
engineering and design costs, (ii) the cost charged to Landlord by Landlord's
general contractor and all subcontractors for performing such construction, and
(iii) the actual cost to Landlord of performing directly any portion of such
construction. Landlord has heretofore competitively bid Landlord's Work for
Phase I to three general contractors and, with Tenant's consent, has selected
Shields Construction as Landlord's general contractor.

     When Landlord's Work for Phase I has been substantially completed, the Cost
of Construction for Phase I will be totaled. If such total (the "Phase I Total")
exceeds an allowance (the "Allowance") of $25.00 per rentable square foot for
Phase I plus $10.00 per rentable square foot for Phase II for a total Allowance
of $1,263,630 ("Phase I Excess Cost"), the amount of the Phase I Excess Cost
shall be due and payable by Tenant to Landlord within thirty (30) days after
Tenant's receipt of Landlord's computation of the Phase I Total, together with
reasonable supporting backup documentation, and a bill for the Phase I Excess
Cost. Such payment shall be due as Additional Rent hereunder.

     If the Phase I Total is less than the Allowance (a "Phase I Cost
Decrease"), the amount of the Phase I Cost Decrease shall be credited against
Tenant's obligation to pay for the Cost of Construction of Phase II as set forth
in the next paragraph.

     When Landlord's Work for Phase II has been substantially completed, the
Cost of Construction for Phase II will be totaled (the "Phase II Total"). If the


                                       3

<PAGE>

Phase II Total exceeds the Phase I Cost Decrease, if any (the "Phase II Excess
Cost"), the amount of the Phase II Excess Cost shall be due and payable by
Tenant to Landlord within thirty (30) days after Tenant's receipt of Landlord's
computation of the Phase II Total, together with reasonable supporting backup
documentation, and a bill for the Phase II Excess Cost. Such payment shall be
due as Additional Rent hereunder.

     If the Phase I Total and the Phase II Total are less than the Allowance
(the "Overall Cost Decrease"), Tenant's Minimum Annual Rent obligation
throughout the Term shall decrease by $0.1619 per year for each $1.00 of the
Overall Cost Decrease, to be apportioned for amounts of such Overall Cost
Decrease which are less than $1.00.

     In no event shall the Phase I Total exceed $1,435,409 unless due to changes
pursuant to subsections 30(d), 30(e) or 30(i)(ii).

     (h) Acceptance of Premises. Section 3 of the Lease is deleted and restated
         ----------------------
as follows:

     "Landlord represents to Tenant that the Property is zoned BC (Business
Campus District). Tenant has been given the opportunity to examine Township's
Zoning Code, and has satisfied itself that such Code will permit the use of the
Property for the conducting of Tenant's business thereon. Tenant's acceptance of
occupancy of the Premises shall, subject to such obligations as are assumed by
Landlord hereunder, and subject to Landlord's warranty obligations as
hereinafter described, constitute Tenant's acceptance of the work which Landlord
is required to perform pursuant to subsection 30(c), and any schedule or exhibit
in this lease, excepting only items listed on the Punch List (as hereinafter
defined). Tenant and its agents shall have the right, at Tenant's own risk,
expense, and responsibility, at all reasonable times prior to the Commencement
Date, upon reasonable prior notice to Landlord, to enter the Premises for the
purpose of taking measurements and installing its furnishings and equipment;
provided that Tenant does not interfere with or delay the work to be performed
by Landlord and Tenant uses contractors and workers compatible with the
contractors and workers engaged by Landlord.

     At or immediately prior to the time Tenant takes occupancy of each of Phase
I and Phase II, a representative of Landlord and a representative of Tenant will
perform a walk-through inspection of such Phase and will prepare a punch list,
if one is required, of any items remaining to be completed, furnished, repaired,
or replaced ("Punch List"). Such Punch List will be signed by a representative
of Landlord and a representative of Tenant. Landlord agrees to cause all items
listed on such Punch List to be performed within thirty (30) days or such longer
period as shall be reasonably required in order to complete such items with
reasonable diligence."

     (i) Term. Section 5 of the Lease is deleted and restated as follows:
         ----

          "(i) The Term of this Lease shall commence on the earlier of (A) the
     date of substantial completion (as hereinafter defined) of the improvements
     to be


                                       4

<PAGE>

     constructed by Landlord to Phase I under subsection 30(c), or (B) the date
     Tenant first uses any portion of the Premises for the conduct of Tenant's
     business (the "COMMENCEMENT DATE") and shall end at 11:59 P.M. on the last
     day of the Term (the "EXPIRATION DATE"), without the necessity for notice
     from either party, unless extended pursuant to the terms of this Lease, or
     sooner terminated in accordance with the terms hereof. Landlord shall
     confirm the Commencement Date and the Expiration Date by executing and
     delivering to Tenant a Lease Commencement Certificate in the form attached
     as Exhibit "B". In the event Tenant disagrees with the Commencement Date
     and the Expiration Date set forth in the Lease Commencement Certificate,
     Tenant shall notify Landlord in writing of its objection thereto, setting
     forth the basis for Tenant's objection. If no written objection to the
     Lease Commencement Certificate is received by Landlord within 10 days after
     Tenant's receipt of the Lease Commencement Certificate, the Commencement
     Date and the Expiration Date set forth in the Lease Commencement
     Certificate shall be conclusively deemed to be accurate.

          If and to the extent that the date of substantial completion of Phase
     I is delayed as a result of a Tenant Delay (as hereinafter defined), the
     Term of this lease and the Commencement Date (for all purposes other than
     Tenant's right to occupy the Premises) and Tenant's obligation to pay rent
     for the Premises shall commence as of the date Phase I would have been
     substantially complete but for such Tenant Delays.

          (ii) As used in this lease, the term "Tenant Delay" shall mean any:

               (A) If a Change Order is signed by both Landlord and Tenant, the
          Change Delay stated therein; or if a request for a Change Order is not
          signed by both Landlord and Tenant, any actual delay resulting from
          Landlord's evaluation of Tenant's Change Order request, and any actual
          delay caused by a work stoppage required in connection with a review
          of Tenant's request for a Change Order; provided that in no case where
          a Change Order is not signed shall Tenant be charged with any such
          delay unless Landlord has given Tenant prior notice that Landlord's
          review of Tenant's Change Order request will cause such delay; and

               (B) Actual delays caused by any of Tenant's installation or
          construction work or Tenant's physical conduct at the Premises
          actually interfering with the progress of Landlord's Work.

               Each Phase of the Premises will be deemed substantially complete
          when Landlord's independent architect shall certify to Tenant as to
          such Phase that (i) all work which Landlord is required to perform
          pursuant to subsection 30(c) has been satisfactorily completed
          (subject only to completion of items set forth on the Punch List),
          (ii) the HVAC, fire protection, electrical systems and all other
          building systems shall be in proper working order and functioning
          (subject to adjustment for seasonal conditions) in accordance with
          design standards set forth herein, the exhibits hereto or the Plans
          and Specifications, (iii) safe access to and egress from all parking
          areas shall be provided, and (iv) all requisite township and state
          certificates of occupancy shall have been delivered by Landlord to
          Tenant, and Tenant shall be able to take occupancy of such Phase and
          fully use and enjoy such Phase for the conduct of its business
          thereon. The foregoing notwithstanding, a Phase shall not be deemed
          other than


                                       5

<PAGE>

          substantially complete by reason of (a) a punch list, if any, of minor
          items remaining to be completed, furnished, repaired, or replaced, (b)
          the issuance of only a temporary certificate of occupancy by the
          township, provided that all conditions to the issuance of all final
          certificates (or other permits) required for Tenant's lawful occupancy
          shall be issued in the ordinary course without the satisfaction of any
          further conditions (including the payment of money or the performance
          of any work), and provided, further, that if any further conditions
          remain to be satisfied, then Landlord shall follow-up with all due
          dispatch to cause the issuance of final certificates of occupancy
          without expense to Tenant or any interference with Tenant's use and
          enjoyment of such Phase. In addition, a Phase shall not be deemed
          other than substantially complete by reason of Landlord's failure at
          the time of substantial completion to deliver a final certificate of
          occupancy from the Commonwealth of Pennsylvania Department of Labor
          and Industry, provided that Tenant shall be permitted to assume lawful
          occupancy of such Phase pending the issuance thereof, and provided,
          further, that if any further conditions remain to be satisfied for the
          issuance thereof, then anything in this Lease contained to the
          contrary notwithstanding (including, without limitation, the limited
          period of Landlord's warranties herein otherwise expressed), Landlord
          shall proceed, at its sole cost and expense and with all due dispatch,
          to cause the issuance of the final certificate of occupancy from the
          Department of Labor and Industry without expense to Tenant and without
          any interference with Tenant's use and enjoyment of such Phase,
          without regard to how long it shall take to cause such certificate to
          be issued. Landlord shall indemnify, defend and save and hold harmless
          Tenant of, from and against any and all loss, cost, expense, damage or
          liability (including reasonable attorneys' fees and costs) sustained
          or incurred by reason of any determination by the Department of Labor
          and Industry or by any other agency or authority that Tenant's use and
          occupancy of such Phase prior to issuance of the said final
          certificate of occupancy was not lawful.

     (j) Notwithstanding anything to the contrary contained in this lease:

          (i) in the event Landlord's Work for Phase I has not been
     substantially completed (as such term is defined in this lease) on or
     before September 1, 1999, as such date shall be extended for Excusable
     Delays, Tenant shall receive a credit of one (1) day's minimum rent for
     each day thereafter until Landlord's Work has been substantially completed.

          (ii) in the event Landlord's Work for Phase I has not been
     substantially completed (as such term is defined in this lease) on or
     before December 31, 1999, as such date shall be extended for Tenant Delays
     (but not for Excusable Delays) (the "Termination Right Date"), Tenant shall
     have the right to terminate this lease upon 30 days' written notice to
     Landlord given within 10 business days after the Termination Right Date,
     provided, however, if Landlord substantially completes (as such term is
     defined in this lease) Landlord's Work for Phase I within such 30 day
     period, Tenant's notice of termination shall be null and void and of no
     further force or effect.

          (iii) in the event Landlord's Work for Phase II has not been
     substantially completed (as such term is defined in this lease) on or
     before the date which is ninety (90) days after issuance of all state and
     local permits required therefor, Rent shall abate for each day thereafter
     until Landlord's Work for Phase II has been substantially completed, such


                                       6

<PAGE>

     abatement to be in the proportion that the rentable square footage of Phase
     II bears to the rentable square footage of the Premises."

     3. Subsection 32(f) is hereby added to the Lease as follows:

          "(f) If Tenant timely exercises its right to lease the Expansion
     Space, Landlord shall construct and complete, at its sole cost and expense,
     Base Building Improvements to the Expansion Space set forth on Exhibit "F"
     attached to this First Amendment in the manner set forth in Section 30(b),
     unless such Base Building Improvements have been previously performed."

     4. Section 61 of the Lease is hereby deleted in its entirety and the
following is substituted therefor:

     "61. Additional Provisions Relating to Security Deposit.
          --------------------------------------------------

     (a) The Security Deposit shall be paid by Tenant to Landlord in cash.
Landlord shall deposit same at Progress Bank, Blue Bell, Pennsylvania ("Bank")
and, with the proceeds thereof, shall purchase, in Landlord's name, five (5)
certificates of deposit, each in the amount of $244,052.20, at Bank's prevailing
interest rates, maturing, respectively, at the end of the second, third, fourth,
fifth and sixth lease years.

     (b) Upon the maturity of each Certificate of Deposit, Landlord shall
present same for payment. Provided that at the time of maturity of any
Certificate of Deposit, Tenant is not in default under this lease after the
expiration of any applicable notice and/or cure period, the principal and
interest received by Landlord upon the maturity of such Certificate of Deposit
shall be paid to Tenant. Interest accrued on each Certificate of Deposit shall
be includable in Tenant's income and not in Landlord's income unless such
interest is actually paid to Landlord and not paid over to Tenant.

     (c) Notwithstanding the foregoing, upon the maturity of the last maturing
Certificate of Deposit, Landlord shall retain, as the cash Security Deposit for
the balance of the Term, an amount equal to 110% of the sum of (i) $79,514.10
(representing the average monthly rent for the last 5 years of the Term), plus
(ii) the then monthly installment of Estimated Annual Operating Expenses being
paid by Tenant under this lease. The cash Security Deposit shall be held by
Landlord in an interest-bearing account at a federally-insured institution for
the balance of the Term, such interest to be paid to Tenant annually provided
Tenant is not then in default under this lease after the expiration of any
applicable notice and/or cure period. Except as otherwise set forth in this
Section 61, the cash Security Deposit shall be held by Landlord in accordance
with the provisions of Section 28 of this lease. Interest accrued on the cash
Security Deposit shall be included in Tenant's income and not in Landlord's
income unless same is actually paid to Landlord and not paid over to Tenant.

     (d) Upon the occurrence of any default by Tenant under this lease which
remains uncured after the expiration of any applicable notice and/or cure
period, Landlord shall have the right, pursuant to Section 28 of this lease, to
liquidate each Certificate of Deposit,


                                       7

whether prior to, at or after maturity, and apply same in accordance with the
provisions of Section 28 of this lease."

     5. Exhibit "F" to the Lease is hereby deleted in its entirety and Exhibit
"F" attached to this First Amendment is inserted in its place.

     6. Section 29 of the Lease is hereby ratified and reaffirmed as follows:

          "29. PA Additional Remedies.
               ----------------------

          (a) When this lease and the Term or any extension thereof shall have
     been terminated on account of any default by Tenant, which remains uncured
     after the expiration of any applicable notice and/or cure period, or when
     the Term or any extension thereof shall have expired, Tenant hereby
     authorizes any attorney of any court of record of the Commonwealth of
     Pennsylvania to appear for Tenant and for anyone claiming by, through or
     under Tenant and to confess judgment against all such parties, and in favor
     of Landlord, in ejectment and for the recovery of possession of the
     Premises, for which this lease or a true and correct copy hereof shall be
     good and sufficient warrant. AFTER THE ENTRY OF ANY SUCH JUDGMENT A WRIT OF
     POSSESSION MAY BE ISSUED THEREON WITHOUT FURTHER NOTICE TO TENANT AND
     WITHOUT A HEARING. If for any reason after such action shall have been
     commenced it shall be determined and possession of the Premises remain in
     or be restored to Tenant, Landlord shall have the right for the same
     default and upon any subsequent default(s) or upon the termination of this
     lease or Tenant's right of possession as herein set forth, to again confess
     judgment as herein provided, for which this lease or a true and correct
     copy hereof shall be good and sufficient warrant.

          (b) The warrant to confess judgment set forth above shall continue in
     full force and effect and be unaffected by amendments to this lease or
     other agreements between Landlord and Tenant even if any such amendments or
     other agreements increase Tenant's obligations or expand the size of the
     Premises. Tenant waives any procedural errors in connection with the entry
     of any such judgment or in the issuance of any one or more writs of
     possession or execution or garnishment thereon.

          (c) EXCEPT AS OTHERWISE SET FORTH IN THIS LEASE, TENANT KNOWINGLY AND
     EXPRESSLY WAIVES ANY RIGHT, INCLUDING, WITHOUT LIMITATION, UNDER ANY
     APPLICABLE STATUTE, WHICH TENANT MAY HAVE TO RECEIVE A NOTICE TO QUIT PRIOR
     TO LANDLORD COMMENCING AN ACTION FOR REPOSSESSION OF THE PREMISES.



                                                     Initials on behalf
                                                             of Tenant: _____

     8. Except as expressly modified herein, the terms and conditions of the
Lease shall remain unchanged and in full force and effect.

     9. This First Amendment shall be binding upon and inure to the benefit of
the parties and their respective successors and permitted assigns.

     IN WITNESS WHEREOF, Landlord and Tenant have executed this First Amendment
as of the day and year first above written.
