                                  BPO-US, INC.

                            STOCK ISSUANCE AGREEMENT


         AGREEMENT made as of this ____ day of ___________ 199__, by and between
BPO-US, Inc., a Delaware corporation, and _____________________, Participant in
the Corporation's 1999 Stock Option/Stock Issuance Plan.

         All capitalized terms in this Agreement shall have the meaning assigned
to them in this Agreement or in the attached Appendix.

         A. PURCHASE OF SHARES

            1. PURCHASE. Participant hereby purchases ___________________ shares
of Common Stock (the "Purchased Shares") pursuant to the provisions of the Stock
Issuance Program at the purchase price of $_______________ per share (the
"Purchase Price").

            2. PAYMENT. Concurrently with the delivery of this Agreement to the
Corporation, Participant shall pay the Purchase Price for the Purchased Shares
in cash or cash equivalent and shall deliver a duly-executed blank Assignment
Separate from Certificate (in the form attached hereto as Exhibit I) with
respect to the Purchased Shares.

            3. STOCKHOLDER RIGHTS. Until such time as the Corporation exercises
the Repurchase Right or the First Refusal Right, Participant (or any successor
in interest) shall have all stockholder rights (including voting, dividend and
liquidation rights) with respect to the Purchased Shares, subject, however, to
the transfer restrictions of Articles B and C.

         B. SECURITIES LAW COMPLIANCE

            1. RESTRICTED SECURITIES. The Purchased Shares have not been
registered under the 1933 Act and are being issued to Participant in reliance
upon the exemption from such registration provided by SEC Rule 701 for stock
issuances under compensatory benefit plans such as the Plan. Participant hereby
confirms that Participant has been informed that the Purchased Shares are
restricted securities under the 1933 Act and may not be resold or transferred
unless the Purchased Shares are first registered under the Federal securities
laws or unless an exemption from such registration is available. Accordingly,
Participant hereby acknowledges that Participant is prepared to hold the
Purchased Shares for an indefinite period and that Participant is aware that SEC
Rule 144 issued under the 1933 Act which exempts certain resales of unrestricted
securities is not presently available to exempt the resale of the Purchased
Shares from the registration requirements of the 1933 Act.

            2. DISPOSITION OF PURCHASED SHARES. Participant shall make no
disposition of the Purchased Shares (other than a Permitted Transfer) unless and
until there is compliance with all of the following requirements:


<PAGE>   2

               (i) Participant shall have provided the Corporation with a
         written summary of the terms and conditions of the proposed
         disposition.

               (ii) Participant shall have complied with all requirements of
         this Agreement applicable to the disposition of the Purchased Shares.

               (iii) Participant shall have provided the Corporation with
         written assurances, in form and substance satisfactory to the
         Corporation, that (a) the proposed disposition does not require
         registration of the Purchased Shares under the 1933 Act or (b) all
         appropriate action necessary for compliance with the registration
         requirements of the 1933 Act or any exemption from registration
         available under the 1933 Act (including Rule 144) has been taken.

         The Corporation shall not be required (i) to transfer on its books any
Purchased Shares which have been sold or transferred in violation of the
provisions of this Agreement or (ii) to treat as the owner of the Purchased
Shares, or otherwise to accord voting, dividend or liquidation rights to, any
transferee to whom the Purchased Shares have been transferred in contravention
of this Agreement.

            3. RESTRICTIVE LEGENDS. The stock certificates for the Purchased
Shares shall be endorsed with one or more of the following restrictive legends:

                "The shares represented by this certificate have not been
registered under the Securities Act of 1933. The shares may not be sold or
offered for sale in the absence of (a) an effective registration statement for
the shares under such Act, (b) a "no action" letter of the Securities and
Exchange Commission with respect to such sale or offer or (c) satisfactory
assurances to the Corporation that registration under such Act is not required
with respect to such sale or offer."

                "The shares represented by this certificate are subject to
certain repurchase rights and rights of first refusal granted to the Corporation
and accordingly may not be sold, assigned, transferred, encumbered, or in any
manner disposed of except in conformity with the terms of a written agreement
dated __________, 199___, between the Corporation and the registered holder of
the shares (or the predecessor in interest to the shares). A copy of such
agreement is maintained at the Corporation's principal corporate offices."

         C. TRANSFER RESTRICTIONS

            1. RESTRICTION ON TRANSFER. Except for any Permitted Transfer,
Participant shall not transfer, assign, encumber or otherwise dispose of any of
the Purchased Shares which are subject to the Repurchase Right. In addition,
Purchased Shares which are released from the Repurchase Right shall not be
transferred, assigned, encumbered or otherwise disposed of in contravention of
the First Refusal Right or the Market Stand-Off.


                                       2.

<PAGE>   3

            2. TRANSFEREE OBLIGATIONS. Each person (other than the Corporation)
to whom the Purchased Shares are transferred by means of a Permitted Transfer
must, as a condition precedent to the validity of such transfer, acknowledge in
writing to the Corporation that such person is bound by the provisions of this
Agreement and that the transferred shares are subject to (i) the Repurchase
Right, (ii) the First Refusal Right and (iii) the Market Stand-Off, to the same
extent such shares would be so subject if retained by Participant.

            3. MARKET STAND-OFF.

               (a) In connection with any underwritten public offering by the
Corporation of its equity securities pursuant to an effective registration
statement filed under the 1933 Act, including the Corporation's initial public
offering, Owner shall not sell, make any short sale of, loan, hypothecate,
pledge, grant any option for the purchase of, or otherwise dispose or transfer
for value or otherwise agree to engage in any of the foregoing transactions with
respect to, any Purchased Shares without the prior written consent of the
Corporation or its underwriters. Such restriction (the "Market Stand-Off") shall
be in effect for such period of time from and after the effective date of the
final prospectus for the offering as may be requested by the Corporation or such
underwriters. In no event, however, shall such period exceed one hundred eighty
(180) days and the Market Stand-Off shall in all events terminate two (2) years
after the effective date of the Corporation's initial public offering.

               (b) Owner shall be subject to the Market Stand-Off provided and
only if the officers and directors of the Corporation are also subject to
similar restrictions.

               (c) Any new, substituted or additional securities which are by
reason of any Recapitalization or Reorganization distributed with respect to the
Purchased Shares shall be immediately subject to the Market Stand-Off, to the
same extent the Purchased Shares are at such time covered by such provisions.

               (d) In order to enforce the Market Stand-Off, the Corporation may
impose stop-transfer instructions with respect to the Purchased Shares until the
end of the applicable stand-off period.

         D. REPURCHASE RIGHT

            1. GRANT. The Corporation is hereby granted the right (the
"Repurchase Right"), exercisable at any time during the sixty (60)-day period
following the date Participant ceases for any reason to remain in Service, to
repurchase at the Purchase Price any or all of the Purchased Shares in which
Participant is not, at the time of his or her cessation of Service, vested in
accordance with the provisions of the Vesting Schedule set forth in Paragraph
D.3 or the special vesting acceleration provisions of Paragraph D.5 (such shares
to be hereinafter referred to as the "Unvested Shares").


                                       3.

<PAGE>   4

            2. EXERCISE OF THE REPURCHASE RIGHT. The Repurchase Right shall be
exercisable by written notice delivered to each Owner of the Unvested Shares
prior to the expiration of the sixty (60)-day exercise period. The notice shall
indicate the number of Unvested Shares to be repurchased and the date on which
the repurchase is to be effected, such date to be not more than thirty (30) days
after the date of such notice. The certificates representing the Unvested Shares
to be repurchased shall be delivered to the Corporation on or before the close
of business on the date specified for the repurchase. Concurrently with the
receipt of such stock certificates, the Corporation shall pay to Owner, in cash
or cash equivalents (including the cancellation of any purchase-money
indebtedness), an amount equal to the Purchase Price previously paid for the
Unvested Shares which are to be repurchased from Owner.

            3. TERMINATION OF THE REPURCHASE RIGHT. The Repurchase Right shall
terminate with respect to any Unvested Shares for which it is not timely
exercised under Paragraph D.2. In addition, the Repurchase Right shall terminate
and cease to be exercisable with respect to any and all Purchased Shares in
which Participant vests in accordance with the following Vesting Schedule:

                Participant shall vest in twenty-five percent (25%) of the
         Purchased Shares, and the Repurchase Right shall concurrently lapse
         with respect to those Purchased Shares, upon Participant's completion
         of one (1) year of Service measured from ___________________, 199_____.

                Participant shall vest in the remaining seventy-five percent
         (75%) of the Purchased Shares, and the Repurchase Right shall
         concurrently lapse with respect to those Purchased Shares, in a series
         of thirty-six (36) successive equal monthly installments upon
         Participant's completion of each additional month of Service over the
         thirty-six (36)-month period measured from the date on which the first
         twenty-five percent (25%) of the Purchased Shares vests hereunder.

            All Purchased Shares as to which the Repurchase Right lapses shall,
however, remain subject to (i) the First Refusal Right and (ii) the Market
Stand-Off.

            4. RECAPITALIZATION. Any new, substituted or additional securities
or other property (including cash paid other than as a regular cash dividend)
which is by reason of any Recapitalization distributed with respect to the
Purchased Shares shall be immediately subject to the Repurchase Right and any
escrow requirements hereunder, but only to the extent the Purchased Shares are
at the time covered by such right or escrow requirements. Appropriate
adjustments to reflect such distribution shall be made to the number and/or
class of Purchased Shares subject to this Agreement and to the price per share
to be paid upon the exercise of the Repurchase Right in order to reflect the
effect of any such Recapitalization upon the Corporation's capital structure;
provided, however, that the aggregate purchase price shall remain the same.


                                       4.


<PAGE>   5

            5. CORPORATE TRANSACTION.

               (a) The Repurchase Right shall automatically terminate in its
entirety, and all the Purchased Shares shall vest in full, immediately prior to
the consummation of any Corporate Transaction, except to the extent the
Repurchase Right is to be assigned to the successor entity in such Corporate
Transaction.

               (b) To the extent the Repurchase Right remains in effect
following a Corporate Transaction, such right shall apply to any new securities
or other property (including any cash payments) received in exchange for the
Purchased Shares in consummation of the Corporate Transaction, but only to the
extent the Purchased Shares are at the time covered by such right. Appropriate
adjustments shall be made to the price per share payable upon exercise of the
Repurchase Right to reflect the effect of the Corporate Transaction upon the
Corporation's capital structure; provided, however, that the aggregate purchase
price shall remain the same. The new securities or other property (including any
cash payments) issued or distributed with respect to the Purchased Shares in
consummation of the Corporate Transaction shall be immediately deposited in
escrow with the Corporation (or the successor entity) and shall not be released
from escrow until Participant vests in such securities or other property in
accordance with the same Vesting Schedule in effect for the Purchased Shares.

               (c) The Repurchase Right may also terminate on an accelerated
basis, and the Purchased Shares shall immediately vest in full, in accordance
with the terms and conditions of any special addendum attached to this
Agreement.

         E. RIGHT OF FIRST REFUSAL

            1. GRANT. The Corporation is hereby granted the right of first
refusal (the "First Refusal Right"), exercisable in connection with any proposed
transfer of the Purchased Shares in which Participant has vested in accordance
with the provisions of Article D. For purposes of this Article E, the term
"transfer" shall include any sale, assignment, pledge, encumbrance or other
disposition of the Purchased Shares intended to be made by Owner, but shall not
include any Permitted Transfer.

            2. NOTICE OF INTENDED DISPOSITION. In the event any Owner of
Purchased Shares in which Participant has vested desires to accept a bona fide
third-party offer for the transfer of any or all of such shares (the Purchased
Shares subject to such offer to be hereinafter referred to as the "Target
Shares"), Owner shall promptly (i) deliver to the Corporation written notice
(the "Disposition Notice") of the terms of the offer, including the purchase
price and the identity of the third-party offeror, and (ii) provide satisfactory
proof that the disposition of the Target Shares to such third-party offeror
would not be in contravention of the provisions set forth in Articles B and C.


                                       5.

<PAGE>   6

            3. EXERCISE OF THE FIRST REFUSAL RIGHT. The Corporation shall, for a
period of twenty-five (25) days following receipt of the Disposition Notice,
have the right to repurchase any or all of the Target Shares subject to the
Disposition Notice upon the same terms as those specified therein or upon such
other terms (not materially different from those specified in the Disposition
Notice) to which Owner consents. Such right shall be exercisable by delivery of
written notice (the "Exercise Notice") to Owner prior to the expiration of the
twenty-five (25)-day exercise period. If such right is exercised with respect to
all the Target Shares, then the Corporation shall effect the repurchase of such
shares, including payment of the purchase price, not more than five (5) business
days after delivery of the Exercise Notice; and at such time the certificates
representing the Target Shares shall be delivered to the Corporation.

            Should the purchase price specified in the Disposition Notice be
payable in property other than cash or evidences of indebtedness, the
Corporation shall have the right to pay the purchase price in the form of cash
equal in amount to the value of such property. If Owner and the Corporation
cannot agree on such cash value within ten (10) days after the Corporation's
receipt of the Disposition Notice, the valuation shall be made by an appraiser
of recognized standing selected by Owner and the Corporation or, if they cannot
agree on an appraiser within twenty (20) days after the Corporation's receipt of
the Disposition Notice, each shall select an appraiser of recognized standing
and the two (2) appraisers shall designate a third appraiser of recognized
standing, whose appraisal shall be determinative of such value. The cost of such
appraisal shall be shared equally by Owner and the Corporation. The closing
shall then be held on the later of (i) the fifth (5th) business day following
delivery of the Exercise Notice or (ii) the fifth (5th) business day after such
valuation shall have been made.

            4. NON-EXERCISE OF THE FIRST REFUSAL RIGHT. In the event the
Exercise Notice is not given to Owner prior to the expiration of the twenty-five
(25)-day exercise period, Owner shall have a period of thirty (30) days
thereafter in which to sell or otherwise dispose of the Target Shares to the
third-party offeror identified in the Disposition Notice upon terms (including
the purchase price) no more favorable to such third-party offeror than those
specified in the Disposition Notice; provided, however, that any such sale or
disposition must not be effected in contravention of the provisions of Articles
B and C. The third-party offeror shall acquire the Target Shares free and clear
of the First Refusal Right, but the acquired shares shall remain subject to the
provisions of Article B and Paragraph C.3. In the event Owner does not effect
such sale or disposition of the Target Shares within the specified thirty
(30)-day period, the First Refusal Right shall continue to be applicable to any
subsequent disposition of the Target Shares by Owner until such right lapses.

            5. PARTIAL EXERCISE OF THE FIRST REFUSAL RIGHT. In the event the
Corporation makes a timely exercise of the First Refusal Right with respect to a
portion, but not all, of the Target Shares specified in the Disposition Notice,
Owner shall have the option, exercisable by written notice to the Corporation
delivered within five (5) business days after Owner's receipt of the Exercise
Notice, to effect the sale of the Target Shares pursuant to either of the
following alternatives:


                                       6.

<PAGE>   7

                (i) sale or other disposition of all the Target Shares to the
         third-party offeror identified in the Disposition Notice, but in full
         compliance with the requirements of Paragraph E.4, as if the
         Corporation did not exercise the First Refusal Right; or

                (ii) sale to the Corporation of the portion of the Target Shares
         which the Corporation has elected to purchase, such sale to be effected
         in substantial conformity with the provisions of Paragraph E.3. The
         First Refusal Right shall continue to be applicable to any subsequent
         disposition of the remaining Target Shares until such right lapses.

         Owner's failure to deliver timely notification to the Corporation shall
be deemed to be an election by Owner to sell the Target Shares pursuant to
alternative (i) above.

            6. RECAPITALIZATION/REORGANIZATION.

               (a) Any new, substituted or additional securities or other
property which is by reason of any Recapitalization distributed with respect to
the Purchased Shares shall be immediately subject to the First Refusal Right,
but only to the extent the Purchased Shares are at the time covered by such
right.

               (b) In the event of a Reorganization, the First Refusal Right
shall remain in full force and effect and shall apply to the new capital stock
or other property received in exchange for the Purchased Shares in consummation
of the Reorganization, but only to the extent the Purchased Shares are at the
time covered by such right.

            7. LAPSE. The First Refusal Right shall lapse upon the earliest to
occur of (i) the first date on which shares of the Common Stock are held of
record by more than five hundred (500) persons, (ii) a determination made by the
Board that a public market exists for the outstanding shares of Common Stock or
(iii) a firm commitment underwritten public offering, pursuant to an effective
registration statement under the 1933 Act, covering the offer and sale of the
Common Stock in the aggregate amount of at least ten million dollars
($10,000,000). However, the Market Stand-Off shall continue to remain in full
force and effect following the lapse of the First Refusal Right.

         F. SPECIAL TAX ELECTION

            1. SECTION 83(b) ELECTION . Under Code Section 83, the excess of the
Fair Market Value of the Purchased Shares on the date any forfeiture
restrictions applicable to such shares lapse over the Purchase Price paid for
such shares will be reportable as ordinary income on the lapse date. For this
purpose, the term "forfeiture restrictions" includes the right of the
Corporation to repurchase the Purchased Shares pursuant to the Repurchase Right.
Participant may elect under Code Section 83(b) to be taxed at the time the
Purchased Shares are acquired, rather than when and as such Purchased Shares
cease to be subject to such forfeiture restrictions. Such election must be filed
with the Internal Revenue Service within thirty (30) days after the


                                       7.


<PAGE>   8

date of this Agreement. Even if the Fair Market Value of the Purchased Shares on
the date of this Agreement equals the Purchase Price paid (and thus no tax is
payable), the election must be made to avoid adverse tax consequences in the
future. THE FORM FOR MAKING THIS ELECTION IS ATTACHED AS EXHIBIT II HERETO.
PARTICIPANT UNDERSTANDS THAT FAILURE TO MAKE THIS FILING WITHIN THE APPLICABLE
THIRTY (30)-DAY PERIOD WILL RESULT IN THE RECOGNITION OF ORDINARY INCOME AS THE
FORFEITURE RESTRICTIONS LAPSE.

            2. FILING RESPONSIBILITY. PARTICIPANT ACKNOWLEDGES THAT IT IS
PARTICIPANT'S SOLE RESPONSIBILITY, AND NOT THE CORPORATION'S, TO FILE A TIMELY
ELECTION UNDER CODE SECTION 83(B), EVEN IF PARTICIPANT REQUESTS THE CORPORATION
OR ITS REPRESENTATIVES TO MAKE THIS FILING ON HIS OR HER BEHALF.

         G. GENERAL PROVISIONS

            1. ASSIGNMENT. The Corporation may assign the Repurchase Right
and/or the First Refusal Right to any person or entity selected by the Board,
including (without limitation) one or more stockholders of the Corporation.

            2. NO EMPLOYMENT OR SERVICE CONTRACT. Nothing in this Agreement or
in the Plan shall confer upon Participant any right to continue in Service for
any period of specific duration or interfere with or otherwise restrict in any
way the rights of the Corporation (or any Parent or Subsidiary employing or
retaining Participant) or of Participant, which rights are hereby expressly
reserved by each, to terminate Participant's Service at any time for any reason,
with or without cause.

            3. NOTICES. Any notice required to be given under this Agreement
shall be in writing and shall be deemed effective upon personal delivery or upon
deposit in the U.S. mail, registered or certified, postage prepaid and properly
addressed to the party entitled to such notice at the address indicated below
such party's signature line on this Agreement or at such other address as such
party may designate by ten (10) days advance written notice under this paragraph
to all other parties to this Agreement.

            4. NO WAIVER. The failure of the Corporation in any instance to
exercise the Repurchase Right or the First Refusal Right shall not constitute a
waiver of any other repurchase rights and/or rights of first refusal that may
subsequently arise under the provisions of this Agreement or any other agreement
between the Corporation and Participant. No waiver of any breach or condition of
this Agreement shall be deemed to be a waiver of any other or subsequent breach
or condition, whether of like or different nature.


                                       8.

<PAGE>   9

            5. CANCELLATION OF SHARES. If the Corporation shall make available,
at the time and place and in the amount and form provided in this Agreement, the
consideration for the Purchased Shares to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
consideration in accordance with this Agreement). Such shares shall be deemed
purchased in accordance with the applicable provisions hereof, and the
Corporation shall be deemed the owner and holder of such shares, whether or not
the certificates therefor have been delivered as required by this Agreement.

         H. MISCELLANEOUS PROVISIONS

            1. GOVERNING LAW. This Agreement shall be governed by, and construed
in accordance with, the laws of the State of California without resort to that
State's conflict-of-laws rules.

            2. PARTICIPANT UNDERTAKING. Participant hereby agrees to take
whatever additional action and execute whatever additional documents the
Corporation may deem necessary or advisable in order to carry out or effect one
or more of the obligations or restrictions imposed on either Participant or the
Purchased Shares pursuant to the provisions of this Agreement.

            3. AGREEMENT IS ENTIRE CONTRACT. This Agreement constitutes the
entire contract between the parties hereto with regard to the subject matter

in all respects be construed in conformity with the terms of the Plan.

            4. COUNTERPARTS. This Agreement may be executed in counterparts,
each of which shall be deemed to be an original, but all of which together shall
constitute one and the same instrument.

            5. SUCCESSORS AND ASSIGNS. The provisions of this Agreement shall
inure to the benefit of, and be binding upon, the Corporation and its successors
and assigns and upon Participant, Participant's assigns and the legal
representatives, heirs and legatees of Participant's estate, whether or not any
such person shall have become a party to this Agreement and have agreed in
writing to join herein and be bound by the terms hereof.
