          2.8  Litigation. There is no action, suit, proceeding or investigation
pending or, to the knowledge of the Company, currently threatened against the
Company that questions the validity of this Agreement, the Investors' Rights

of the Company, nor is the Company aware that there is any basis for the
foregoing. The foregoing includes, without limitation, actions, suits,
proceedings or investigations pending or, to the knowledge of the Company,
threatened (or any basis therefor known to the Company) involving the prior
employment of any of the Company's employees, their use in connection with the
Company's business of any information or techniques allegedly proprietary to any
of their former employers, or their obligations under any agreements with prior

service marks, trade names, copyrights, trade secrets, information, proprietary
rights and processes, whether or not registered, necessary for its business as
now conducted and as proposed to be conducted (including with respect to its
eBusiness Express product line) without any conflict with or infringement of the
rights of others. There are no outstanding options, licenses, royalties, or
other agreements of any kind relating to the foregoing, nor is the Company bound
by or a party to any options, licenses or agreements of any kind with respect to
the patents, trademarks, service marks, trade names, copyrights, trade secrets,
licenses, information, proprietary rights and processes of any other person or
entity. The Company has not received any communications alleging that the

<PAGE>   9
proposed, would violate any of the patents, trademarks, service marks, trade
names, copyrights or trade secrets or other proprietary rights of any other
person or entity. After due investigation, the Company is not aware that any of
its employees is obligated under any contract (including licenses, covenants or
commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere with
the use of his or her best efforts to promote the interests of the Company or
that would conflict with the Company's business as proposed to be conducted.
Neither the execution nor delivery of this Agreement, the Investors' Rights
Agreement or the Co-Sale Agreement, nor the carrying on of the Company's
business by the employees of the Company, nor the conduct of the Company's
business as proposed, will, to the Company's knowledge, conflict with or result
in a breach of the terms, conditions or provisions of, or constitute a default
under, any contract, covenant or instrument under which any of such employees is
now obligated. The Company does not believe it is or will be necessary to
utilize any inventions of any of its employees (or people it currently intends
to hire) made prior to their employment by the Company.

          2.11 Compliance with Other Instruments. The Company is not in
violation or default of any provision of its Restated Certificate or Bylaws, or
of any instrument, judgment, order, writ, decree or contract to which it is a
party or by which it is bound, or, to its knowledge, of any provision of any
federal or state statute, rule or regulation applicable to the Company. The
execution, delivery and performance of this Agreement, the Investors' Rights
Agreement and the Co-Sale Agreement, and the consummation of the transactions
contemplated hereby and thereby will not result in any such violation or be in
conflict with or constitute, with or without the passage of time and giving of
notice, either a default under any such provision, instrument, judgment, order,
writ, decree or contract or an event that results in the creation of any lien,
charge or encumbrance upon any assets of the Company or the suspension,
revocation, impairment, forfeiture, or nonrenewal of any material permit,
license, authorization, or approval applicable to the Company, its business or
operations or any of its assets or properties.

other form of acquisition, liquidation, dissolution or winding up of the

the Company or member of his or her immediate family is indebted to the Company,
nor is the Company indebted (or committed to make loans or extend or guarantee

persons has any direct or indirect ownership interest in any firm or corporation

relationship, or any firm or corporation that competes with the Company. No
member of the immediate family of any officer or director of the Company is
directly or indirectly interested in any material contract with the Company.

that the unaudited Financial Statements may not contain all footnotes required
by generally accepted accounting principles. The Financial Statements fairly
present the financial condition and operating results of the Company as of the
dates, and for the periods, indicated therein, subject in the case of the
unaudited Financial Statements to normal year-end audit adjustments. Except as
set forth in the Financial Statements, the Company has no material liabilities,
contingent or otherwise, other than (i) liabilities incurred in the ordinary
course of business subsequent to December __, 1999, and (ii) obligations under
contracts and commitments incurred in the ordinary course of business and not
required under generally accepted accounting principles to be reflected in the
Financial Statements, which, in both cases, individually or in the aggregate,
are not material to the financial condition or operating results of the Company.

          2.22 Changes. Since November 30, 1999, there has not been:

               (a) any change in the assets, liabilities, financial condition or
operating results of the Company from that reflected in the Financial
Statements, except changes in the ordinary course of business that have not
been, in the aggregate, materially adverse;

               (b) any damage, destruction or loss, whether or not covered by
insurance, materially and adversely affecting the assets, properties, financial
condition,

<PAGE>   13
operating results, prospects or business of the Company (as such business is
presently conducted and as it is proposed to be conducted);

               (c) any waiver by the Company of a material right or of a
material debt owed to it;

               (d) any satisfaction or discharge of any lien, claim or
encumbrance or payment of any obligation by the Company, except in the ordinary
course of business and that is not material to the assets, properties, financial
condition, operating results or business of the Company (as such business is
presently conducted and as it is proposed to be conducted);

               (e) any material change or amendment to a material contract or
arrangement by which the Company or any of its assets or properties is bound or
subject;

               (f) any sale, assignment or transfer of any patents, trademarks,
copyrights, trade secrets or other intangible assets other than the licensing of
the Company's products in the ordinary course of business;

               (g) any resignation or termination of employment of any key
employee or officer of the Company; and the Company, to the best of its
knowledge, does not know of the impending resignation or termination of
employment of any such key employee or officer;

               (h) receipt by an executive officer of the Company of notice that
there has been a loss of, or material order cancellation by, any major customer
of the Company;

               (i) any mortgage, pledge, transfer of a security interest in, or
lien, created by the Company, with respect to any of its material properties or
assets, except liens for taxes not yet due or payable;

               (j) any loans or guarantees made by the Company to or for the
benefit of its employees, officers or directors, or any members of their
immediate families, other than travel advances and other advances made in the
ordinary course of its business;

               (k) any declaration, setting aside or payment of any dividend or
other distribution in respect of any of the Company's capital stock, or any
direct or indirect redemption, purchase or other acquisition of any of such
stock by the Company;

               (l) to the best of the Company's knowledge, any other event or
condition of any character that might materially and adversely affect the
assets, properties, financial condition, operating results or business of the
Company (as such business is presently conducted and as it is proposed to be
conducted); or

<PAGE>   14
               (m) any agreement or commitment by the Company to do any of the
things described in this Section 2.22.

          2.23 Insurance. The Company has in full force and effect fire,
casualty and liability insurance policies with recognized insurers with such
coverages as are sufficient in amount to allow replacement of the tangible
properties of the Company that might be damaged or destroyed.

          2.24 Employee Benefit Plans. Except as set forth in Section 2.24 of
the Webridge, Inc. Schedule of Exceptions hereto, the Company does not have any
Employee Benefit Plan as defined in the Employee Retirement Income Security Act
of 1974 ("ERISA"). To the Company's knowledge, each of the Company's Employee
Benefit Plans is in full compliance with ERISA and the Company has no
liabilities associated with any Employee Benefit Plan other than those
liabilities set forth in the Financial Statements.

          2.25 Tax Returns and Payments. The Company has filed all tax returns
and reports as required by law. These returns and reports are true and correct
in all material respects. The Company has paid all taxes and other assessments
when due, except those contested by it in good faith that are listed in the
Schedule of Exceptions. The provision for taxes of the Company as shown in the
Financial Statements is adequate for taxes due or accrued as of the date
thereof. The Company has not elected pursuant to the Internal Revenue Code of
1986, as amended (the "Code"), to be treated as a collapsible corporation
pursuant to Section 341(f) of the Code, nor has it made any other elections
pursuant to the Code (other than elections that relate solely to methods of
accounting, depreciation or amortization) that would have a material adverse
effect on the Company, its financial condition, its business as presently
conducted or proposed to be conducted or any of its properties or material
assets.

          2.26 Labor Agreements and Actions. The Company is not bound by or
subject to (and none of its assets or properties is bound by or subject to) any
written or oral, express or implied, contract, commitment or arrangement with
any labor union, and no labor union has requested or, to the best knowledge of
the Company, has sought to represent any of the employees, representatives or
agents of the Company. There is no strike or other labor dispute involving the
Company pending, or to the best knowledge of the Company threatened, which could
have a material adverse effect on the assets, properties, financial condition,
operating results, or business of the Company (as such business is presently
conducted and as it is proposed to be conducted), nor is the Company aware of
any labor organization activity involving its employees.

          2.27 Environmental and Safety Laws. To the best of the Company's
knowledge, it is not in violation of any applicable statute, law or regulation
relating to the environment or occupational health and safety that would have a
material effect on the employees, and to the best of its knowledge, no material
expenditures are or will be required in order to comply with any such existing
statute, law or regulation.

<PAGE>   15
          2.28 Minute Books. The copy of the minute books of the Company
provided to the counsel for the Investors contains minutes of all meetings of
directors and stockholders and all actions by written consent without a meeting
by the directors and stockholders since the date of incorporation and reflects
all actions by the directors (and any committee of directors) and stockholders
with respect to all transactions referred to in such minutes accurately in all
material respects.

          2.29 Year 2000. Software developed by the Company for sale or license
to its customers (including Mainspan) is Year 2000 compliant. As used in this
Agreement, "Year 2000 compliant" means that the software is designed to be used
prior to, during and after the calendar year 2000, and the software will
accurately receive, provide and process date and time data from, into and
between the 20th and 21st centuries, including the years 1999 and 2000, and
leapyear calculations and will not malfunction, cease to function, or provide
invalid or incorrect results as a result of date and time data, to the extent
that other software used in combination with the Company's software properly
exchanges date and time data with it.

     3.   Representations and Warranties of the Investors. Each Investor hereby
represents and warrants that:

          3.1  Authorization. Such Investor has full power and authority to
enter into this Agreement, the Investors' Rights Agreement and the Co-Sale
Agreement, and each such Agreement constitutes its valid and legally binding
obligation, enforceable in accordance with their respective terms, except (i) as
limited by applicable bankruptcy, insolvency, reorganization, moratorium, and
other laws of general application affecting enforcement of creditors' rights
generally, (ii) as limited by laws relating to the availability of specific
performance, injunctive relief, or other equitable remedies, and (iii) to the
extent the indemnification provisions contained in the Investors' Rights
Agreement may be limited by applicable federal or state securities laws.

          3.2  Purchase Entirely for Own Account. This Agreement is made with
such Investor in reliance upon such Investor's representation to the Company,
which by such Investor's execution of this Agreement such Investor hereby
confirms, that the Series C Preferred Stock to be received by such Investor and
the Common Stock issuable upon conversion thereof (collectively, the
"Securities") will be acquired for investment for such Investor's own account,
not as a nominee or agent, and not with a view to the resale or distribution of
any part thereof, and that such Investor has no present intention of selling,
granting any participation in, or otherwise distributing the same. By executing
this Agreement, such Investor further represents that such Investor does not
have any contract, undertaking, agreement or arrangement with any person to
sell, transfer or grant participations to such person or to any third person,
with respect to any of the Securities.

          3.3  Disclosure of Information. Such Investor believes it has received
all the information it considers necessary or appropriate for deciding whether
to purchase the Series C Preferred Stock. Such Investor further represents that
it has had an opportunity to ask questions and receive answers from the Company
regarding the terms and conditions of the

<PAGE>   16
offering of the Series C Preferred Stock and the business, properties, prospects
and financial condition of the Company. The foregoing, however, does not limit
or modify the representations and warranties of the Company in Section 2 of this
Agreement or the right of the Investors to rely thereon and assumes the accuracy
thereof.

          3.4  Investment Experience. Such Investor is an investor in securities
of companies in the development stage and acknowledges that it is able to fend
for itself, can bear the economic risk of its investment, and has such knowledge
and experience in financial or business matters that it is capable of evaluating
the merits and risks of the investment in the Series C Preferred Stock. If other
than an individual, Investor also represents it has not been organized for the
purpose of acquiring the Series C Preferred Stock.

          3.5  Accredited Investor. Such Investor is an "accredited investor"
within the meaning of Securities and Exchange Commission ("SEC") Rule 501 of
Regulation D, as presently in effect.

          3.6  Restricted Securities. Such Investor understands that the
Securities it is purchasing are characterized as "restricted securities" under
the federal securities laws inasmuch as they are being acquired from the Company
in a transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration under
the Act only in certain limited circumstances. In this connection, such Investor
represents that it is familiar with SEC Rule 144, as presently in effect, and
understands the resale limitations imposed thereby and by the Act.

          3.7  Further Limitations on Disposition. Without in any way limiting
the representations set forth above, such Investor further agrees not to make
any disposition of all or any portion of the Securities unless and until the
transferee has agreed in writing for the benefit of the Company to be bound by
this Section 3 and the Investors' Rights Agreement provided and to the extent
this Section and such agreement are then applicable, and:

               (a) There is then in effect a Registration Statement under the
Act covering such proposed disposition and such disposition is made in
accordance with such Registration Statement; or

               (b) (i) Such Investor shall have notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii) if
reasonably requested by the Company, such Investor shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company that
such disposition will not require registration of such shares under the Act. It
is agreed that the Company will not require opinions of counsel for transactions
made pursuant to Rule 144 except in unusual circumstances.

               (c) Notwithstanding the provisions of paragraphs (a) and (b)
above, no such registration statement or opinion of counsel shall be necessary
for a transfer by an Investor that is a partnership, corporation or limited
liability company to another entity that

<PAGE>   17
controls, is controlled by, or is under common control with the transferring
entity or to a partner or member of such transferring partnership or limited
liability company or a retired partner or member of such partnership or limited
liability company who retires after the date hereof, or to the estate of any
such person or retired person or the transfer by gift, will or intestate
succession of any such person to his or her spouse or to the siblings, lineal
descendants or ancestors of such person or his or her spouse, if the transferee
agrees in writing to be subject to the terms hereof to the same extent as if he
or she were an original Investor hereunder.

          3.8  Legends. It is understood that the certificates evidencing the
Securities may bear one or all of the following legends:

               (a) "These securities have not been registered under the
Securities Act of 1933, as amended. They may not be sold, offered for sale,
pledged or hypothecated in the absence of a registration statement in effect
with respect to the securities under such Act or under applicable state law or
an opinion of counsel satisfactory to the Company that such registration is not
required or unless sold pursuant to Rule 144 of such Act."

               (b) The legends set forth in the Investors' Rights Agreement and
the Co-Sale Agreement.

     4.   Conditions of Investor's Obligations at Closing. The obligations of
each Investor under subsection 1.1(b) of this Agreement are subject to the
