                                   EXCLUSIVITY

Section 5.1. PEOPLESOFT EXCLUSIVITY. For a period commencing on the Effective
Date and ending on January 1, 2001, PeopleSoft shall not enter into an agreement
with Commerce One Specified Companies to Distribute or develop products similar
to the BuySite Products, the MarketSite Services and the associated software.
PeopleSoft shall use the MarketSite Services as its exclusive MRO Portals and
PeopleSoft shall not Distribute or develop any other hosted MRO Portals or enter
into any agreement with any third party with respect to any MRO Portal during
the period of this exclusivity. For the term of this Agreement, PeopleSoft shall
not provide a Source Code or Object Code license to the BuySite Products to a
Commerce One Specified Company. If, at any time commencing on the Effective Date
and ending on January 1, 2001 , PeopleSoft is in breach of the exclusivity
provisions of this Section 5.1 or assigns this Agreement through operation of
law, merger or acquisition of all or substantially all of its assets to a
Commerce One Specified Company, without limiting any other rights or remedies of
Commerce One, Commerce One shall be entitled to change the exclusivity set forth
in Sections 5.1 (a) and 5.3 below to non-exclusive by providing PeopleSoft with
written notice thereof. Nothing in this Section 5.1 shall be construed as
terminating this Agreement or the licenses granted herein.

     (a) PEOPLESOFT EXCLUSIVE ACCOUNTS. During the term of the Agreement and
subject to Section 5.3(a) and (b) below, PeopleSoft shall have the sole and
exclusive right, (except as to Grandfathered Resellers) to market and Distribute
the Products to the PeopleSoft Named Accounts other than PeopleSoft Named
Accounts within the Telco Industry.

Section 5.2. PEOPLESOFT MINIMUMS. Commencing on the Effective Date, and subject
to the potential extended period under Section 5.6 below, PeopleSoft shall enter
into licenses for the Products either directly or indirectly through
Distributors, with the projected cumulative sales targets set forth on
Attachment I (the "Minimum Targets"). For the purpose of this Section 5.2, any
license entered into by PeopleSoft or Commerce One with a Commerce One Named
Account pursuant to Section 5.3(a) below shall be considered a license by
PeopleSoft for the purpose of calculating the Total Customers as defined in
Attachment B. In the event that the Total Customers are not, at a minimum, equal
to the cumulative Minimum Target for any two consecutive calendar quarters,
Commerce One shall be entitled to demand and receive a change to the grant of
exclusivity set forth in Section 5.1(a) above to non-exclusive by written notice
to PeopleSoft; provided, however, that PeopleSoft shall first have the
opportunity to cure the possible loss of exclusivity as follows:


                                      -7-
<PAGE>

     If PeopleSoft does not meet the cumulative Minimum Target as of the end of
any two consecutive calendar quarters, PeopleSoft may, by the thirtieth (30th)
day ("Cure Date") of the calendar quarter immediately following the second
consecutive calendar quarter in which the cumulative Minimum Target was missed
(the "Cure Quarter"), pay a prepaid nonrefundable royalty creditable against
future licenses entered into by PeopleSoft in an amount equal to the average
PeopleSoft Net Fees received per End User for licenses entered into (not
including access agreements to MarketSite Services) by PeopleSoft for the twelve
(12) months preceding the beginning of the Cure Quarter, multiplied by "X",
where "X" is the Minimum Target as of the expiration of the second consecutive
calendar quarter, less the actual number of Total Customers licensed or sold
access to MarketSite Services, as applicable, as of the expiration of the second
consecutive calendar quarter ("Cure Cost"). It is understood and agreed that if
at the end of the Cure Quarter, PeopleSoft has entered into sufficient licenses
or access agreements to meet the Minimum Target as of end of the Cure Quarter
and paid the Cure Cost to Commerce One, then PeopleSoft shall be entitled to
retain the right of exclusivity under Section 5.1 above.

     By way of numerical example only, if, the Minimum Target for the tenth
(10th), eleventh (11th) and twelfth (12th) quarters are ninety-five (95), one
hundred and five (105) and one hundred and twenty (120) licenses or access
agreements for MarketSite Services, respectively, and the average PeopleSoft Net
Fees received per End User for licenses (but not including access agreements for
MarketSite Services) over the twelve (12) months prior to the beginning of the
Cure Quarter is equal to $500,000 ("X" = $500,000); and, PeopleSoft does not
meet the cumulative Minimum Target in the tenth (10th) quarter and enters into
only one hundred (100) licenses or access agreements to MarketSite Services by
the end of the eleventh (11th) quarter ("Total Customer" as defined in Section
14 of Attachment B herein), PeopleSoft will have missed the cumulative Minimum
Target for two (2) consecutive calendar quarters. The Cure Cost shall be equal
to the product obtained by multiplying $500,000 by five (5) (where five shall
have been calculated by subtracting the Total Customers at the end of the
eleventh quarter (100) from the cumulative Minimum Target as of the end of the
eleventh quarter (105)), or $2,500,000. If at the end of the twelfth quarter,
PeopleSoft shall have met the Minimum Target (120) and paid the Cure Cost of
$2,500,000, then PeopleSoft shall continue to retain its exclusivity.

     Section 5.3. COMMERCE ONE EXCLUSIVITY. For a period commencing on the
Effective Date and ending on January 1, 2001, Commerce One shall not enter into
an agreement with PeopleSoft Specified Companies to Distribute, sell or develop
products similar to the Products or MarketSite Services. Notwithstanding the
foregoing, Commerce One may enter into an Agreement with SAP only for the
purpose of becoming ISV certified and with Oracle for the purpose of database
development. If, at any time during the eighteen (18) months from the Effective
Date, Commerce One is in breach of the exclusivity provisions of this Section
5.3 or assigns this Agreement through operation of law, merger or acquisition of
all or substantially all of its assets to a Specified Company, without limiting
any other rights or remedies of PeopleSoft, PeopleSoft shall be entitled to
change the exclusivity set forth in Section 5.1 above or 5.3(a) below to
non-exclusive by providing Commerce One with written notice thereof. Nothing in
this Section 5.3 shall be construed as terminating this Agreement or the
licenses granted herein.


                                      -8-
<PAGE>

(a) COMMERCE ONE EXCLUSIVE ACCOUNT. Notwithstanding Section 5.1(a)
above, for a period of [  *  ] after the Effective Date, Commerce One
shall have the exclusive right to Distribute the Products to the Commerce One
Named Accounts. In the event any of the Commerce One Named Accounts enters into
a license during such [  *  ] period, such license may be between either
Commerce One or PeopleSoft and such individual Commerce One Named Account. Such
Commerce One Named Account shall pay fees to either Commerce One or PeopleSoft,
who shall then allocate the fees as set forth in Attachment B. Nothing in this
Section shall prohibit or discourage PeopleSoft from cooperatively engaging with
Commerce One with respect to Commerce One Named Accounts.

     (b) COMMERCE ONE EXCLUSIVE ACCOUNT. Notwithstanding Section 5.1 (a) above,
for a period of [  *  ] after the Effective Date, Commerce One shall have
the exclusive right to market and Distribute the BuySite Products to the Telco
Named Accounts.

     (c) TELCO NAMED ACCOUNTS. From the Effective Date, PeopleSoft has a
non-exclusive right to Distribute the Products to the Telco Industry, excluding
the Telco Named Accounts. Commencing at the beginning of the [  *  ]
after the Effective Date, PeopleSoft shall be at liberty to Distribute to the
Telco Named Accounts.

     Section 5.4. LIMITED RIGHT TO WORK WITH SPECIFIED COMPANIES FOR END USER
CUSTOMER-REQUESTED IMPLEMENTATIONS.

     (a) The parties contemplate that only on a rare case-by-case basis both
parties may, due to an insistent End User customer request, need to work on such
End User-requested implementations with respect to Specified Company's products
and each party may, for such rare cases, provide services to such End User
notwithstanding the provisions of Sections 5.1 and 5.3. Prior to undertaking or
so agreeing to such an implementation effort, the requested party must first use
all reasonable efforts to direct the customer to an external independent third
party implementor to conduct the work for the End User. The parties shall also
use all reasonable efforts, primarily expected to be conducted through their
alliance personnel, to provide advance written notice (which shall include by
electronic mail) of at least five (5) business days to the other of a situation
whereby the requested party has attempted and failed to persuade the End User to
use an independent third party implementor and that the party is considering
entering into an End User agreement to provide the future direct implementation
services to the End User for the Specified Company product.

(b) The intent of this Section is that implementations for a
Specified Company conducted by the Parties shall be the rare exception rather
than the rule, and in the event such End User requested implementations occur on
at least two occasions within any six month period, the Parties acknowledge that
this is cause for concern and therefore the Parties' executive liaisons will
promptly have face-to-face meeting(s) to discuss this issue to resolve the issue
to their mutual satisfaction.

occur: (a) the period of exclusivity set forth in this Section 5 shall be
extended solely for the benefit of PeopleSoft by one whole calendar quarter
for each calendar quarter or portion thereof it takes for BuySite 6.0 to be
delivered and accepted pursuant to the terms of the Joint Development
Agreement and (b) the target dates for all Minimum Targets as set forth in
Section 5.2 and Attachment I shall be adjusted forward by one whole calendar
quarter for each calendar quarter or portion thereof it takes for BuySite 6.0

extended until [  *  ] and all Minimum Targets as set forth in Section 5.2
shall be adjusted forward by one whole quarter, beginning with the Minimum
Target of sixty (60) at the end of [  *  ]. As further example, if BuySite
6.0 is delivered and accepted on any day from [  *  ] through [  *  ] the
period of exclusivity shall be extended through [  *  ] and all Minimum
Targets as set forth in Section 5.2 shall be adjusted forward one quarter
beginning with the Minimum Target of sixty (60) at the end of [  *  ].

Section 5.7. LIMIT TO EXCLUSIVITY. Nothing in this Agreement shall prevent
PeopleSoft from entering into Agreements with third parties to integrate any
product or service content into the PeopleSoft Products.

Section 5.8. GOVERNMENT PROCUREMENT SOLUTION. In the event PeopleSoft elects to
move forward with a government procurement solution, PeopleSoft grants to
Commerce One a right to negotiate with regard to partnering to provide a
government procurement solution. In the event the parties enter into such
negotiations, the parties shall conclude a definitive agreement or material

credits toward the purchase of MarketSite Direct Services or refunds, at
PeopleSoft's option, shall be issued by Commerce One to PeopleSoft, the amount

reincorporation into Delaware (the "Delaware Reincorporation"), certain shares
of the Common Stock;

     WHEREAS, such sale and purchase of Common Stock shall occur immediately

                (b) At the Closing, the Purchaser shall pay the purchase
price (the "Purchase Price") for the shares of Common Stock purchased hereunder

subject to a stop transfer order with the Company's transfer agent that
restricts the transfer of the Purchased Shares except in compliance with this
Agreement.

          1.2   CLOSING.

     The closing of the purchase and sale of the Purchased Shares (the
"Closing") shall take place at the offices of Wilson Sonsini Goodrich & Rosati,

conducted.  Neither the execution nor delivery of this Agreement or the other
Transaction Agreements, nor the carrying on of the Company's business as
conducted or as currently proposed to be conducted, 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 that it is or will be necessary for the Company to utilize
any inventions of any of its employees made prior to their employment with
the Company.

          2.10  COMPLIANCE WITH OTHER INSTRUMENTS.

applicable to the Company, including but not limited to the Foreign Corrupt
Practices Act.  The execution, delivery and performance of this Agreement and
the other Transaction Agreements and the consummation of the Transactions 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 which results in the creation of any lien, charge or encumbrance upon any
of the properties or 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. No consent, approval, qualification, order
or authorization of, or filing with, any governmental authority, or any consent

With respect to the property and assets it leases, the Company is in compliance

interest free of any liens, claims or encumbrances.  Other than ordinary wear

for which they are being used, and are adequate and sufficient for the Company's
business.

the consummation or performance by the Purchaser of any of the Transactions to
be consummated or performed by it, will directly or indirectly (with or without
notice or lapse of time): (i) violate any provision of the Purchaser's
certificate or articles of incorporation or bylaws or other charter documents;
(ii) constitute or result in a breach or default by the Purchaser, or give rise

          3.6   INVESTMENT REPRESENTATIONS.

                (a)  The Purchaser understands that none of the Purchased
Shares has been registered under the Securities Act. The Purchaser also
understands that the Purchased Shares are being offered and sold pursuant to an
exemption from registration contained in the Securities Act based in part upon
the Purchaser's representations contained in this Agreement, and that the

representations, warranties, acknowledgements and understandings with respect to
a material fact set forth herein.

                (b)  The Purchaser is acquiring the Purchased Shares for the

of making a public distribution thereof.

                (c)  The Purchaser has substantial experience in evaluating and
investing in private placement transactions of securities in companies similar
to the Company so that it is capable of evaluating the merits and risks of its
investment in the Company and has the capacity to protect its own interests. The
Purchaser, by reason of its business or financial experience, has the capacity
to protect its own interests in connection with the Transactions. The Purchaser
is an "accredited investor" as that term is defined in Rule 501(a) of Regulation
D.

                (d)  The Purchaser acknowledges that the Purchased Shares must
be held indefinitely and that the Purchaser must bear the economic risk of this
investment indefinitely unless the Purchased Shares are subsequently registered
under the Securities Act or an exemption from such registration is available.
The Purchaser understands that the Company has no present intention of
registering the Purchased Shares. The Purchaser also understands that there is
no assurance that any exemption from registration under the Securities Act will
be available and that, even if available, such exemption may not allow the
Purchaser to transfer all or any portion of the Purchased Shares under the
circumstances, in the amounts or at the times the Purchaser might propose.

                (e)  The Purchaser has been advised or is aware of the
provisions of Rule 144 under the Securities Act ("Rule 144"), which permit
limited resale of shares purchased in a private placement subject to the
satisfaction of certain conditions, including, among other things: (i) the
availability of certain current public information about the Company, (ii) the
resale occurring not less than one year after a party has purchased and paid for
the security to be sold, (iii) the sale being through an unsolicited "broker's
transaction" or in transactions directly with a market maker (as said term is
defined under the Exchange Act) and (iv) the number of shares being sold during
any three-month period not exceeding specified limitations.

                (f)  The Purchaser initiated discussions with the Company
relating to the purchase and sale contemplated by this Agreement on an
unsolicited basis prior to the date of this Agreement. The Purchaser did not
receive any information regarding such purchase and sale through any general
solicitation or general advertising within the meaning of Rule 502(c) under the
Securities Act.

Company in this Agreement, the Purchaser has been afforded the opportunity to
obtain any additional information deemed necessary by the Purchaser to verify
the accuracy of any representations made or information conveyed to the
Purchaser. The Purchaser confirms that all documents, records and books
pertaining to its investment in Common Stock and requested by the Purchaser have

           STOCK PURCHASE AND MASTER STRATEGIC RELATIONSHIP AGREEMENT

     This Stock Purchase and Master Strategic Relationship Agreement (this
"Agreement") is entered into as of May ___, 1999, by and between Commerce One,
Inc., a California corporation (the "Company"), and SingTel Ventures (Cayman)
Pte Limited, a corporation organized under the laws of Cayman Islands (the
"Purchaser"). Capitalized terms used in this Agreement and not otherwise defined
are defined in EXHIBIT A attached hereto.

     WHEREAS, the Purchaser wishes to purchase from the Company, and the Company
wishes to issue and sell to the Purchaser, following the Company's
reincorporation into Delaware (the "Delaware Reincorporation"), certain shares
of the Common Stock;

     WHEREAS, such sale and purchase of Common Stock shall occur immediately
following the closing of the Company's initial public offering (the "IPO").

     NOW, THEREFORE, in consideration of the mutual promises and covenants
herein, the parties hereto, intending to be legally bound, agree as follows:

     1. AGREEMENT TO SELL AND PURCHASE SHARES; OTHER AGREEMENTS

          1.1 SALE AND PURCHASE OF SHARES.

               (a) Subject to the terms and conditions hereof, at the Closing,
the Company will issue and sell to the Purchaser, and the Purchaser will
purchase from the Company, shares of Common Stock equal in number to $5,000,000
divided by the Per Share Price. The "Per Share Price" shall be equal to the IPO
Price multiplied by 94%.

               (b) At the Closing, the Purchaser shall pay the purchase price
(the "Purchase Price") for the shares of Common Stock purchased hereunder (the
"Purchased Shares") by wire transfer of immediately available funds in U.S.
dollars to an account specified in writing by the Company prior to the Closing.

               (c) No fractional shares shall be issued upon the sale of any
Common Stock to the Purchaser pursuant to this Agreement, and the number of
shares of Common Stock to be issued to the Purchaser shall be rounded to the
nearest whole share.

               (d) All certificates representing the Purchased Shares shall bear
the following legend:

                    (i) "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN
ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE "ACT"). SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE
ABSENCE OF REGISTRATION OR AN EXEMPTION THEREFROM. THE COMPANY MAY REQUIRE AN
OPINION OF COUNSEL


<PAGE>

REASONABLY ACCEPTABLE TO IT THAT A PROPOSED TRANSFER OR SALE IS IN COMPLIANCE
WITH THE ACT. COPIES OF THE AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND
RESTRICTING THEIR TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY
THE HOLDERS OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY AT THE
PRINCIPAL EXECUTIVE OFFICES OF THE COMPANY."

                    (ii) Any legend required by the blue sky or securities laws
of any state or jurisdiction to the extent such laws are applicable to the
shares represented by the certificate so legended.

               (e) The certificates representing the Purchased Shares will be
subject to a stop transfer order with the Company's transfer agent that
restricts the transfer of the Purchased Shares except in compliance with this
Agreement.

          1.2 CLOSING.

     The closing of the purchase and sale of the Purchased Shares (the
"Closing") shall take place at the offices of Wilson Sonsini Goodrich & Rosati,
Professional Corporation, 650 Page Mill Road, Palo Alto, California 94304, at
11:00 a.m. (California time) on the date of and immediately following the
closing of the IPO, or on such other date or at such other place or time as the
Company and the Purchaser may mutually agree (such date, the "Closing Date").

     2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY

corporate power and authority to carry on its business as now conducted and as
proposed to be conducted. Each of the Company and VEO is duly qualified as a
foreign corporation to transact business and is in good standing in each
jurisdiction in which the nature of its business or the location of its
properties requires such qualification and in which the failure to so qualify
would have a material adverse effect on its business. In connection with the
IPO, as of the Closing Date, the Company shall be incorporated in the State of
Delaware and VEO shall be a wholly-owned subsidiary of the Company duly
organized, validly existing and in good standing under the laws of the State of

          2.7 GOVERNMENTAL CONSENTS.

     No consent, approval or authorization of or designation, declaration or

     There is no action, suit, arbitration, proceeding or investigation pending
or currently threatened against the Company or its properties before any court,

basis for the foregoing. The foregoing includes, without limitation, actions,
suits, arbitration proceedings or investigations pending or 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 employers. The
Company is not a party or subject to the provisions of any order, writ,
injunction, judgment or decree of any court of government agency or
instrumentality. There is no action, suit, proceeding or investigation by the
Company currently pending or that the Company intends to initiate.

          2.9 INTELLECTUAL PROPERTY.

     As of the Closing, the Company has legally enforceable rights to use all
patents, trademarks, service marks, trade names, copyrights, trade secrets,
information, proprietary rights, know-how and processes necessary for its
business as now conducted and as proposed to be conducted without any conflict
with or infringement on the rights of others, except as may otherwise be
described in Section 2.9 of the Disclosure Schedule. Except pursuant to
Contracts (as defined in Section 2.11 below) listed in the Disclosure Schedule,
copies of which have previously been delivered to the Purchasers, there are no
outstanding options, licenses, or 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, know-how and processes of any other person or entity. Except as
described in Section 2.9 of the Disclosure Schedule, to the best of the
Company's knowledge the Company has not violated or, by conducting its business
as proposed, would not violate any of the patents, trademarks, service marks,
trade names, copyrights or trade secrets or other proprietary rights of any
other person or entity. Each current or former employee, officer, director and
consultant of the Company has executed an agreement with the Company regarding


                                      -5-
<PAGE>

confidentiality and proprietary information, a copy of the form of which has
previously been provided to the Purchasers, and no exceptions have been taken by
any such current or former employee, officer or consultant. 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 conducted
or proposed to be conducted. Neither the execution nor delivery of this
Agreement or the other Transaction Agreements, nor the carrying on of the
Company's business as conducted or as currently proposed to be conducted, 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 that it is or will be necessary for the Company to
utilize any inventions of any of its employees made prior to their employment
with the Company.

          2.10 COMPLIANCE WITH OTHER INSTRUMENTS.

     The Company is not in violation or default of any provisions of its charter
documents or of any instrument, judgment, order, writ, decree or contract to
which it is a party or by which it is bound or, of any provision of federal,
state or foreign statute, rule, regulation, order or restriction applicable to
the Company, including but not limited to the Foreign Corrupt Practices Act. The
execution, delivery and performance of this Agreement and the other Transaction
Agreements and the consummation of the Transactions 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 which results
in the creation of any lien, charge or encumbrance upon any of the properties or
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. No consent, approval, qualification, order or authorization of, or
filing with, any governmental authority, or any consent or approval of any third
party person or entity is required in connection with the Company's valid
execution, delivery or performance of this Agreement or the offer, sale or
issuance of the Purchased Shares, or the consummation of any other transaction
contemplated on the part of the Company hereby, except as required in connection
with the Delaware Reincorporation and for the filing of any notice required by
applicable Blue Sky laws, the filing of a notice on Form D, the filing of any
notice required by applicable foreign securities laws. Except as disclosed in
the Disclosure Schedule, the Company has avoided every condition and has not

applicable state and federal laws concerning the offer, sale and issuance of

                     (f) Neither the offer nor the issuance or sale of the

agreement or instrument to which the Company is a party or by which it is bound
or affected, which shall either increase the number of shares or units of
capital stock issuable upon conversion of any securities or upon exercise of
any warrant or right to subscribe to or purchase any stock or similar security,

         No consent, approval or authorization of or designation, declaration
or filing with any governmental authority on the part of the Company is
required in connection with the valid execution and delivery of this
Agreement, or the consummation of the transactions contemplated, hereby or
thereby, except as required in connection with the Delaware Reincorporation
and for the filing of notices required by applicable Blue Sky laws, the
filing of a Form D pursuant to Regulation D under the Securities Act of 1933,

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 employers. The
Company is not a party or subject to the provisions of any order, writ,
injunction, judgment or decree of any court of government agency or
instrumentality. There is no action, suit, proceeding or investigation by the
Company currently pending or that the Company intends to initiate.

                2.9 INTELLECTUAL PROPERTY.

         As of the Closing, the Company has legally enforceable rights to use
all patents, trademarks, service marks, trade names, copyrights, trade
secrets, information, proprietary rights, know-how and processes necessary
for its business as now conducted and as proposed to be conducted without any
conflict with or infringement on the rights of others, except as may
otherwise be described in Section 2.9 of the Disclosure Schedule. Except
pursuant to Contracts (as defined in Section 2.11 below) listed in the
Disclosure Schedule, copies of which have previously been delivered to the
Purchasers, there are no outstanding options, licenses, or 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, know-how and processes of any other person
or entity. Except as described in Section 2.9 of the Disclosure Schedule, to
the best of the Company's knowledge the Company has not violated or, by
conducting its business as proposed, would not violate any of the patents,
trademarks, service marks, trade names, copyrights or trade secrets or other
proprietary rights of any other person or entity. Each current or former
employee, officer, director and consultant of the Company has executed an
agreement with the Company regarding confidentiality and proprietary
information, a copy of the form of which has previously been provided to the
Purchasers, and no exceptions have been taken by any such current or former
employee, officer or consultant. 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 conducted or
proposed to be conducted. Neither the execution nor delivery of this
Agreement or the other Transaction Agreements, nor the carrying on of the
Company's business as conducted or as currently proposed to be conducted,
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 that it is or will be necessary for
the Company to utilize any inventions of any of its employees made prior to
their employment with the Company. Since its organization, the Company has
taken reasonable security measures to protect the secrecy, confidentiality,
and value of its trade secrets, including know-how, negative processes,
inventions, designs, computer programs, technical data and all information
that derives independent economic value, actual or potential, from not being
generally known or known by competitors.

                2.10 COMPLIANCE WITH OTHER INSTRUMENTS.

contract to which it is a party or by which it is bound or, of any provision

applicable to the Company, including but not limited to the Foreign Corrupt
Practices Act. The execution, delivery and performance of this Agreement and
the other Transaction Agreements and the consummation of the transactions
contemplated hereby 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 which results in the creation of any lien,
charge or encumbrance upon any of the properties or 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. No
consent, approval, qualification, order or authorization of, or filing with,
any governmental authority, or any consent or approval of any third party
person or entity is required in connection with the Company's valid
execution, delivery or performance of this Agreement or the offer, sale or
issuance of the Purchased Shares, or the consummation of any other
transaction contemplated on the part of the Company hereby, except as
required in connection with the Delaware Reincorporation and for the filing
of any notice required by applicable Blue Sky laws, the filing of a notice on
Form D, the filing of any notice required by applicable foreign securities
laws. Except as disclosed in the Disclosure Schedule, the Company has avoided
every condition and has not performed any act which would result in the
Company's loss of any right granted under any license, distribution or other
agreement.

                2.11 MATERIAL CONTRACTS AND COMMITMENTS.

         Except as listed in Section 2.11 of the Disclosure Schedule and except

business and ordinary course licensing agreements entered into with customers of
the Company). All of the Contracts are valid, binding and in full force and
effect in all material respects and enforceable by the Company in accordance
with their respective terms in all material respects, subject to the effect of
applicable bankruptcy, insolvency, reorganization, fraudulent conveyance,
moratorium, usury or other laws of general application relating to or affecting
enforcement of creditors' rights and rules or laws concerning equitable
remedies. The Company is not in material default under any of such Contracts,
nor has the Company received notice that any third party does not intend to
renew any material contract it currently has with the Company, or that any third
party intends to terminate any material contract currently in place with the
Company. To the best knowledge of the Company, no other party to any of the
Contracts is in material default thereunder. Except for the merger of the
Company and VEO, the Company has not engaged in the past six (6) months in any
discussion (i) with any representative of any corporation or corporations
regarding the consolidation or merger of the Company with or into any such
corporation or corporations, (ii) with any corporation,

(iii) regarding any other form of acquisition, liquidation, dissolution or
winding up of the Company.

                2.12 REGISTRATION RIGHTS.

Registration Rights Agreement, as amended, the Company shall not be under any
contractual obligation to register any of its presently outstanding securities
or any of its securities which may hereafter be issued.  As of the Closing,
except as set forth in this Agreement or the Fourth Amended and Restated
Registration Rights Agreement, there are no agreements, written or oral, between
the Company and any of its shareholders or among any shareholders, relating to
the acquisition, disposition or voting of the capital stock of the Company.

                2.13 TITLE TO PROPERTY AND ASSETS.

         The Company has good and marketable title to its property and assets,
free and clear of all mortgages, liens, loans and encumbrances, except such
encumbrances and liens which arise in the ordinary course of business and do not
materially impair the Company's ownership or use of such property or assets.
With respect to the property and assets it leases, the Company is in compliance
with such leases and, to the best of its knowledge, holds a valid leasehold
interest free of any liens, claims or encumbrances. Other than ordinary wear and
tear, all tangible assets owned or leased by the Company are in good operating
condition and repair, are reasonably fit and usable for the purposes for which
they are being used, and are adequate and sufficient for the Company's business.

<PAGE>

advised that any of its returns, federal, state or other, have been or are being
audited as of the date hereof, and no deficiency assessment or proposed
adjustment of the Company's United States income tax or state or municipal taxes
is pending or, to the best knowledge of the Company, threatened. The provision
for taxes for the Company as shown in the Financial Statements and Unaudited
Financial Statements is adequate for taxes due or accrued as of the date
thereof. Since the date of the Financial Statements and Unaudited Financial
Statements, the Company has made adequate provisions on its books of account for
all taxes, assessments and governmental charges with respect to its business,
properties and operations for such period. The Company has withheld or collected
from each payment made to each of its employees the amount of all taxes
(including, but not limited to, federal income taxes, Federal Insurance
Contribution Act taxes and Federal Unemployment Tax Act taxes) required to be
withheld or collected therefrom and has paid the same to the proper tax
receiving officers or authorized depositaries.

                2.18 EMPLOYEES AND EMPLOYEE BENEFIT PLANS.

Company who has any plans to terminate his or her employment with the Company.
Except as described in Section 2.18 of the Disclosure Schedule, the Company does
not have any deferred compensation, pension, profit sharing, bonus, insurance,
severance or other similar employee benefit plan or obligation covering any of
its employees or any plan subject to the Employee Retirement Income Security Act
of 1974, as amended ("ERISA"). To the Company's knowledge, the Company has
complied with all applicable state and federal equal employment opportunity and
other laws relating to employment. The Company has not made any loans or
advances to any person other than ordinary expenses for travel expenses. There
is no strike or other labor dispute involving the Company pending, or to the
best of the Company's knowledge, threatened, that 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. The Company has no written employment
agreement or contract with any employee of the Company.

                     (c) Except as set forth in Section 2.18 of the Disclosure

benefit plans ("Plans"), as defined in Section 3(3) of ERISA. The Company has no

limitation, any unfunded liability or any accumulated funding deficiency) or any
material liability to the Pension Benefit Guaranty Corporation ("PBGC") or under
Title IV of ERISA, with respect to a multi-employer pension benefit plan, nor
would the Company have any such liability if any such plan were terminated or if
the Company withdrew, in whole or in part, from any multi-employer plan. To the
Company's best knowledge, the Company's ERISA Plans are in compliance in all
material respects with ERISA, the Internal Revenue Code and other applicable
legal requirements. The Company has filed all reports required to be filed by it
prior to the filing


                                      -11-

<PAGE>

deadlines (including extensions) with the Internal Revenue Service or the PBGC
under ERISA and the Internal Revenue Code.

                2.19 CERTAIN TRANSACTIONS.

         Except as set forth in Section 2.19 of the Disclosure Schedule, the
Company is not indebted, directly or indirectly, to any of its officers,
directors or shareholders or to their spouses or children, in any amount
whatsoever; and none of said officers, directors or, to the best of the
Company's knowledge, shareholders, or any member of their immediate families,
are indebted to the Company or have any direct or indirect ownership interest in
any firm or corporation with which the Company is affiliated or with which the
Company has a business relationship (except as a holder of securities of a

extent and in the manner customary for companies in similar businesses similarly
situated.

                2.21 PERMITS.

         The Company has all franchises, permits, licenses, and any similar
authority necessary for the conduct of its business as now being conducted by
it, the lack of which could reasonably be expected to have a material adverse
effect on the Company, and the Company believes it can obtain, without undue
burden or expense, any similar authority for the conduct of its business as
planned to be conducted. The Company is not in default in any material respect
under any of such franchises, permits, licenses, or other similar authority.

                2.22 ENVIRONMENTAL AND SAFETY LAWS.

         The Company is not in violation of any applicable federal, state or
local statute, law or regulation relating to the environment or occupational
health and safety, and no material expenditures are or will be required in
order to comply with any such existing statute, law or regulation.

         No representation or warranty of the Company contained in this
Agreement, or in any other Transactional Agreement, or any certificate furnished
or to be furnished to the Purchaser at the Closing, when read together, contains

                                      -12-

         3. REPRESENTATIONS AND WARRANTIES OF THE PURCHASER

         The Purchaser hereby represents and warrants to the Company as follows:

                3.1 ORGANIZATION AND GOOD STANDING.

Purchaser. Each of this Agreement and such other Transactional Agreements
constitutes, or upon execution and delivery will constitute, the legal, valid
and binding obligation of the Purchaser, enforceable against the Purchaser in
accordance with its terms, except as limited by (i) applicable bankruptcy,
insolvency, reorganization, moratorium or other laws of general application
affecting enforcement of creditors' rights, and (ii) laws relating to the
availability of specific performance, injunctive relief or other equitable
remedies.

                3.3 NON-CONTRAVENTION; CONSENTS.

                     (a) Neither the execution and delivery by the Purchaser,
nor the consummation or performance by the Purchaser of any of the Transactions
to be consummated or performed by it, will directly or indirectly (with or
without notice or lapse of time): (i) violate any provision of the Purchaser's
certificate or articles of incorporation or bylaws or other charter documents;
(ii) constitute or result in a breach or default by the Purchaser, or give rise
to a right of termination on the part of any other party, or result in the
creation or imposition of any lien, claim or encumbrance on any Purchaser
assets, under any agreement or instrument to which the Purchaser is a party or
by which the Purchaser is bound; or (iii) constitute a violation by the
Purchaser of any Requirement of Law, except that the approval of the Japanese
Ministry of Post and Telecommunications is required to consummate the
Transactions.

                     (b) Except for compliance with the terms of Sections 13
and 16 of the Exchange Act (if required) and except for the approval of the
Japanese Ministry of Post and Telecommunications, no consent, approval, order
or authorization of, or registration, qualification, designation, declaration
or filing with, any Governmental Authority on the part of the Purchaser is
required in connection with the consummation of the Transactions.

                3.4 LITIGATION.

         As of the date hereof, there are no suits, proceedings or
investigations pending or, to the knowledge of the Purchaser, threatened against
the Purchaser, which in any such case would


                                      -13-

<PAGE>

materially adversely affect the Purchaser's ability to perform its obligations
under this Agreement or any of the other Transactional Agreements.

          3.5  BROKERS.

     The Purchaser has not granted or become obligated to pay, or taken any
action that likely would result in any Person claiming to be entitled to receive
from the Company, any brokerage commission, finder's fee or similar commission
or fee in connection with any of the Transactions.

          3.6  INVESTMENT REPRESENTATIONS.

               (a)  The Purchaser understands that none of the Purchased Shares
has been registered under the Securities Act. The Purchaser also understands
that the Purchased Shares are being offered and sold pursuant to an exemption
from registration contained in the Securities Act based in part upon the
Purchaser's representations contained in this Agreement, and that the Company is
relying upon the truth and accuracy of the Purchaser's representations,
warranties, acknowledgements and understandings with respect to a material fact
set forth herein.

               (b)  The Purchaser is acquiring the Purchased Shares for the
Purchaser's own account for investment only, and not with the current intention
of making a public distribution thereof.

               (c)  The Purchaser has substantial experience in evaluating and
investing in private placement transactions of securities in companies similar
to the Company so that it is capable of evaluating the merits and risks of its
investment in the Company and has the capacity to protect its own interests. The
Purchaser, by reason of its business or financial experience, has the capacity
to protect its own interests in connection with the Transactions. The Purchaser
is an "accredited investor" as that term is defined in Rule 501(a) of Regulation
D.

               (d)  The Purchaser acknowledges that the Purchased Shares must be
held indefinitely and that the Purchaser must bear the economic risk of this

under the Securities Act or an exemption from such registration is available.
Without limiting the obligations of the Company under the Fourth Amended and
Restated Rights Agreement, as amended, the Purchaser understands that the
Company has no present intention of registering the Purchased Shares. The
Purchaser also understands that there is no assurance that any exemption from
registration under the Securities Act will be available and that, even if
available, such exemption may not allow the Purchaser to transfer all or any
portion of the Purchased Shares under the circumstances, in the amounts or at
the times the Purchaser might propose.

               (e)  The Purchaser has been advised or is aware of the provisions
of Rule 144 under the Securities Act ("Rule 144"), which permit limited resale
of shares purchased in a private placement subject to the satisfaction of
certain conditions, including, among other things: (i) the availability of
certain current public information about the Company, (ii) the resale occurring
not less than one year after a party has purchased and paid for the security to
be sold, (iii) the sale being through an unsolicited "broker's transaction" or
in transactions directly with a market maker (as said


                                         -14-
<PAGE>

term is defined under the Exchange Act) and (iv) the number of shares being sold
during any three-month period not exceeding specified limitations.

               (f)  The Purchaser initiated discussions with the Company
relating to the purchase and sale contemplated by this Agreement on an
unsolicited basis prior to the date of this Agreement. The Purchaser did not
receive any information regarding such purchase and sale through any general
solicitation or general advertising within the meaning of Rule 502(c) under the
Securities Act.

          3.7  COMPANY DISCLOSURE DOCUMENTS.

               (a)  The Purchaser has received and reviewed a copy of the
Company's Registration Statement on Form S-1, as filed with the Securities and
Exchange Commission on April 26, 1999 (the "Registration Statement"), including,
without limitation, the language therein under the caption "Risk Factors."

               (b)  The Purchaser has been furnished with materials relating to
the Company and its proposed activities, including, without limitation, the
Registration Statement. Without limiting the Company's obligations with respect
to any representations or warranties made by the Company in this Agreement, the
Purchaser has been afforded the opportunity to obtain any additional information
deemed necessary by the Purchaser to verify the accuracy of any representations
made or information conveyed to the Purchaser. The Purchaser confirms that all
documents, records and books pertaining to its investment in Common Stock and
requested by the Purchaser have been made available or delivered to the
Purchaser. The Purchaser has had an opportunity to ask questions of and receive
answers from the Company, or from a person or persons acting on the Company's
behalf, concerning the terms and conditions of this investment.

          3.8  FOREIGN OFFERING REPRESENTATIONS.

               (a)  No offer or solicitation of an offer was made by the
Company, any of its affiliates or any other person acting for or on behalf of
the Company, to the Purchaser to enter into this Agreement, or to consummate the
transactions contemplated hereby (including, without limitation, the issuance of
the Purchased Shares), while the Purchaser was inside the United States and, at
the time of the execution and delivery by the Purchaser of this Agreement, the
Purchaser was outside the United States.

               (b)  In making the decision to invest in the shares of the
Company's Common Stock to be issued hereto, the Purchaser has not relied upon
any materials received in connection with any "directed selling efforts" of the
Company, any of its affiliates or any person acting for or on behalf of the
Company, as such term is defined in Rule 902(b) under Regulation S ("Regulation
S") promulgated under the Securities Act of 1933, as amended (the "Securities
Act"), including, without limitation, any printed materials distributed in a
publication with a general circulation within the United States, or
advertisements with radio or television stations broadcasting within the United
States, in each case which discuss the terms of this Agreement or the
transactions contemplated hereby (including, without limitation, the issuance of
the Purchased Shares pursuant hereto).


                                         -15-
<PAGE>

               (c)  In making the decision  to invest in the shares of the
Company's Common Stock to be issued pursuant hereto, the Purchaser has not
relied upon any "Distributors", as such term is defined in Rule 902(c) of
Regulation S, including, without limitation, any underwriter or dealer.

               (d)  The Purchaser understands and acknowledges that the
Purchased Shares to be issued pursuant hereto are being issued in reliance upon
the exemption from the registration requirements of the Securities Act afforded
by Regulation S, that such shares will not be registered under the Securities
Act or any state securities or "blue sky" law, and that such shares may not be
offered or sold in the United States or to any "U.S. Person", as such term is
defined in Rule 902(o) of Regulation S ( a "U.S. Person"), or otherwise disposed
of, except in accordance with the provisions of Rules 903 and 904 of Regulation
S, pursuant to registration of such shares under the Securities Act, or pursuant
to another available exemption from the registration requirements of the
Securities Act.

               (e)  Purchaser is not a U.S. Person, and the Purchaser is not
acquiring the Purchased Shares for the account or benefit of any U.S. Person.

               (f)  The Purchaser understands and acknowledges that it may not
resell any of the Purchased Shares to be issued pursuant hereto unless any such
resale is effected in accordance with the provisions of Rule 904 of Regulation
S, pursuant to registration of such resale under the Securities Act, or pursuant
to another available exemption from the registration requirements of the
Securities Act.

successors, assigns, heirs, executors and administrators of the parties hereto.
Except as otherwise expressly provided herein, neither party may assign any of
its rights or obligations hereunder without the written consent of the other
party hereto; PROVIDED, HOWEVER, that the Company shall have the right, with or
without the consent of the Purchaser, to reincorporate into Delaware prior to
the Closing and such Delaware successor corporation will succeed to all of the
Company's rights and obligations under this Agreement.

               (b)  In the event of a transfer of the rights and obligations of
the Purchaser under this Agreement pursuant to a statutory reorganization of the
Purchaser prescribed in the Supplementary Provisions to the Law Concerning
Partial Amendment to the Nippon Telegraph and Telephone Corporation Law (Law No.
98 of 1997) (the "Amendment"), the Purchaser shall ensure that all the rights
and obligations of the Purchaser under this Agreement and the ownership of the
Purchased Shares are transferred to the said successor entity without any
dilution or adverse effect on the enforceability of such obligations.  Subject
to the aforesaid, the Company: (i) agrees that such a reorganization by itself
shall not constitute a default by the Purchaser or any successor entity of the
Purchaser under this Agreement and shall not constitute grounds for termination
of this Agreement by any of such parties; (ii) anything to the contrary herein
or elsewhere notwithstanding, consents to the transfer of all the rights and
obligations of the Purchaser under this Agreement to a successor entity as part
of such reorganization; (iii) consents to the transfer of the Purchaser Shares
to a


                                         -20-

successor entity as part of such reorganization; and (iv) anything to the
contrary herein or elsewhere notwithstanding, agrees to absolutely and
irrevocably release the Purchaser from its obligations under this Agreement and
the other Transactional Agreements upon such reorganization, provided, in each
case, that the successor entity shall be subject to the terms and conditions of
this Agreement and the other Transactional Agreements, including, without
limitation, the representations and warranties of the Purchaser herein and in
the other Transactional Agreements, and shall deliver to the Company a written
agreement to such effect, in form and substance reasonably satisfactory to the
Company, and provided, further, in each case, that the successor entity is
either one of the Regional Companies or the Long Distance Company currently
contemplated in the Amendment.

or federal court located in the County of Contra Costa, California, any claim
that such party is not subject personally to the jurisdiction of such court,
that such legal proceeding has been brought in an inconvenient forum, that the
venue of such proceeding is improper or that this Agreement or the other
Transactional Agreements or the subject matter hereof or thereof may not be
enforced in or by such court.
