                                    RECITALS

         A. The Company, the Founders and the Series A Holders have entered into

         C. A condition to the obligations of the Series B Holders under the

into this Agreement for the purpose of setting forth the terms and conditions
under which the Investors and the Founders shall, in certain cases, vote their
shares of the Company's voting stock in favor of certain designees to the

         D. The Company, the Founders, and the Series A Holders desire to amend

the Company, for the election of Fuyuhiko Usui or another representative of

                           (e) For so long as Jeffrey W. Dunn remains the Chief

                           (f) For so long as Nancy E. Bush remains the Chief
Financial Officer of the Company or holds at least two percent (2%) of the

                  1.2 Appointment of Directors. In the event of the resignation,
death, removal or disqualification of a director selected by the Investors, such
Investors shall promptly nominate a new director and, after written notice of
the nomination has been given by such Investors to the other parties, each
Founder and Investor shall promptly vote its shares of capital stock of the
Company to elect such nominee to the Board of Directors.

                  1.3 Removal. The Investors may at any time and from time to
time, remove, with or without cause (subject to the Bylaws of the Company as in
effect from time to time and any requirements of law), in their sole discretion,
their designated director or directors and, after written notice to each of the
parties hereto of the new nominee(s) to replace such director(s), each Investor
shall promptly vote its shares of capital stock of the Company to elect such
nominee to the Board of Directors of the Company.

                  1.4 Other Voting. This Agreement shall not extend to voting
upon questions and matters (other than the election of directors) upon which
shareholders of the Company have a right to vote under the Articles of
Incorporation or Bylaws of the Company or under the laws of the State of
California.

         2. No Revocation. The voting agreements contained herein are coupled
with an interest and may not be revoked during the term of this Agreement.

                  THE SHARES REPRESENTED BY THIS CERTIFICATE ARE
                  SUBJECT TO A VOTING AGREEMENT BETWEEN THE

         4. Transfer of Rights. No Founder or Investor shall sell, assign,
transfer, pledge, hypothecate, mortgage or dispose of, by gift or otherwise, any
shares of capital stock then owned by such Investor or Founder unless the person
acquiring such capital stock of the Company shall first become a signatory to
this Agreement, agreeing to be bound by all the terms of this Agreement to the
same extent as if such person had been an original signatory hereto. The Company
shall not transfer any shares of its capital stock on its books which shall have
been sold, assigned or otherwise transferred in violation of this Agreement, or
to treat as owner of such shares of its capital stock, or to record the right to
vote as such owner or to pay dividends to, any person or organization to which
any such shares of its capital stock shall have been sold, assigned or otherwise
transferred, from and after any sale, assignment or transfer of any share of its
capital stock made in violation of this Agreement.

         5. Term. This Agreement shall be effective as of the date first above
written and shall terminate and be of no further force or effect upon the
earlier to occur of (a) the consummation of the Company's sale of its Common
Stock in a bona fide, firm commitment underwriting pursuant to a registration
statement under the Securities Act of 1933, as amended (other than a
registration statement relating either to the sale of securities to employees of
the Company pursuant to a stock option, stock purchase or similar plan or a SEC
Rule 145 transaction), (b) such time as the Company becomes subject to the
reporting requirements of the Securities Exchange Act of 1934, as amended, or

                           (c) Any party may, by written notice to the other,
alter its address or respondent, and such notice shall be considered to have

                  6.2 Successors and Assigns. The terms and conditions of this
Agreement shall inure to the benefit of and be binding upon the respective
successors and assigns of the parties. Nothing in this Agreement, express or
implied, is intended to confer upon any party other than the parties hereto or
their respective successors and assigns any rights, remedies, obligations, or
liabilities under or by reason of this Agreement, except as expressly provided
in this Agreement.

                  6.3 Severability. If one or more provisions of this Agreement
are held to be unenforceable under applicable law, portions of such provisions,
or such provisions in their entirety, to the extent necessary, shall be severed
from this Agreement, and the balance of the Agreement shall be interpreted as if
such provision were so excluded and shall be enforceable in accordance with its
terms.

                  6.4 Entire Agreement; Modifications and Amendments. This
Agreement and the documents referred to herein constitute the entire agreement
between the parties hereto pertaining to the subject matter hereof, and any and
all other written or oral agreements existing among the parties hereto are
expressly canceled. This Agreement may be modified or amended only with the
written consent of the Company, each Founder and at least a majority of the
shares of Common Stock Equivalents held by the Investors or their permitted
successors or assigns. In no event shall such waiver of any rights hereunder
constitute the waiver of such rights in any future instance unless the waiver so
specifies in writing. Any amendment or waiver effected in accordance with this
Section 6.5 shall be binding upon each of the parties hereto and each transferee
of the Common Stock Equivalents.

                  6.5 Governing Law. This Agreement shall be governed by and
construed under the laws of the State of California as applied to agreements
entered into solely between residents of, and to be performed entirely within,
such state.

                  6.6 Counterparts. This Agreement may be executed in two or
more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

                  6.7 Best Efforts. The Company agrees to use its best efforts
to enforce the terms of this Agreement, to inform the Investors and the Founders
of any breach hereof and to assist the Investors and the Founders in the
exercise of their rights and performance of their obligations hereunder. The
Investors and each Founder expressly agree that the Investors, the Founders and
the Company will be irreparably damaged if this Agreement is not specifically
enforced. Upon a breach or threatened breach of the terms, covenants and/or
conditions of this Agreement by any of the Founders or the Investors, each of
the Founders, the Investors and the Company shall, in addition to all other
remedies, each be entitled to a temporary or permanent 

                                      -4-
<PAGE>   5
injunction, without showing any actual damage, and/or a decree for specific
performance, in accordance with the provisions hereof.

                  6.8 Legal Fees. In the event of any action at law, suit in
equity or arbitration proceeding in relation to this Agreement or any shares or
other securities of the Company transferred hereunder, the prevailing party, or
parties, shall be paid by the other party or parties a reasonable sum for
attorneys' fees, costs and expenses in addition to any other relief to which
such prevailing party may be entitled.

                  6.9 Titles and Subtitles. The titles and subtitles used in
this Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

                  6.10 Termination of Prior Rights. Effective and contingent
upon execution of this Agreement by each of the Founders and holders of a
majority of the capital stock owned by the holders of Series A Preferred Stock,
and upon the closing of the transactions contemplated by the Series B Purchase
Agreement, the Prior Voting Agreement is hereby declared null and void and is
amended and restated in its entirety to read as set forth in this Agreement, and
the Company, the Founders and the Investors hereby agree to be bound by the
provisions hereof as the sole agreement of the Company, the Founders and the
Investors with respect to certain voting rights. Upon termination of the Prior
Voting Agreement as aforesaid, this Agreement is hereby entered into on behalf
of all of the Founders and the Series A Holders as provided in Section 6.4 of
the Prior Voting Agreement.
