Subsidiary has an obligation to indemnify, to any tax or penalty imposed under
Section 4975 of the Code or Section 502 of ERISA.  The Company and its
Subsidiaries will enter into proprietary rights and invention assignment

employee incentive stock option plan substantially in the form attached as
Exhibit K hereto (the "New Option Plan", and together with the Company's 1997
Stock Option Plan, the "Option Plans"). Subject to the terms and conditions of
the Option Plans, options issued pursuant to the Option Plans shall be
exercisable for up to 14,829,000 shares of the outstanding Common Stock (subject
to adjustment for stock splits, stock

                                     -16-

dividends, recapitalizations and similar transactions) and, to the extent issued
under the New Option Plan, shall have exercise prices of $1.00 per share or
greater.

               4.11.  Stock Option Vesting.  All Stock (or options therefor)
                      --------------------
granted by the Company under the New Option Plan shall vest as follows, unless
otherwise agreed by the Board of Directors: 10,423,200 shares shall vest ratably
25% per year of service measured from the vesting commencement date and
2,605,800 shares shall vest upon the closing of a Qualified IPO or any merger,
consolidation, liquidation or dissolution which results in gross proceeds in
cash or marketable securities of at least $4.05 per share. The terms of each
grant shall provide that upon termination of the employment of the holder, with
or without cause, the Company or its assignee (to the extent permissible under
applicable securities laws) retains the option to repurchase at cost any vested
share held by such holder.

               4.12.  Redemption Premium.  The Company and the Purchasers
                      ------------------
acknowledge that under the regulations of the United States Department of
Treasury, the issuance of the Series C Preferred Stock and Warrants for an
aggregate, combined purchase price will result in the creation of a "redemption
premium" on the Series C Preferred Stock equal to the value of the Warrants.
After taking into account all relevant factors (including the fact that no
public market for the Common Stock currently exists, the general condition of
the financial markets at this time, the liquidation preferences of senior
securities of the Company, the exercise price for shares of Common Stock
issuable upon exercise of the Warrants, the nature of the rights provided for in
the Warrants and all other matters concerning the transactions contemplated by
this Agreement), the Company and the Purchasers agree that the aggregate
redemption premium on the Series C Preferred Stock (i.e., the aggregate value of
the Warrants) shall be $50,000. The redemption premium will be allocated pro
rata among the shares of Series C Preferred Stock. Neither the Company nor any
Purchaser will take any position for United Stated Federal income tax purposes
that is inconsistent with the provisions of this Section 4.12.

<PAGE>

each person who controls such Purchaser within the meaning of the Securities
Act or the Exchange Act, from and against any and all costs, expenses
(including, without limitation, reaso nable attorneys' fees, whether incurred in
connection with a claim against the Company or a third party claim), damages or
other liabilities (collectively, "Losses") resulting from any breach of any
                                  ------
representation, warranty, covenant or agreement set forth in this Agreement or
any Related Document by the Company or any legal, administrative or other
proceedings brought by any third party arising out of the transactions
contemplated hereby and thereby (other than Losses resulting, directly or
indirectly, (i) from the breach by such Purchaser of any of its agreements
contained in this Agreement or any Related Document or (ii) from the gross
negligence or willful misconduct of such Purchaser or any of its respective
officers, directors, partners, employees or agents, or any person who controls
such Purchaser within the meaning of the Securities Act or the Exchange Act);
provided, however, that, if and to the extent that such indemnification is
--------  -------
unenforceable for any reason, the Company shall make the maximum contribution to
the payment and satisfaction of such indemnified liability which shall be
permissible under applicable laws.

               (c)  Each party entitled to indemnification under this Section
6.9 (each, an "indemnified party") will, promptly after the receipt of notice of
               -----------------
the commencement of any action against such indemnified party in respect of
which indemnity may be sought from a party (each, an "indemnifying party") on
                                                      ------------------
account of an indemnity agreement contained in this Section 6.9, notify the
indemnifying party in writing of the commencement thereof. The omission of any
indemnified party so to notify the indemnifying party of any such action shall
not relieve the indemnifying party from any liability which the indemnifying
party may have to such indemnified party except to the extent the indemnifying
party shall have been materially prejudiced by the omission of such indemnified
party so to notify the indemnifying party pursuant to this Section 6.9. In case
any such action shall be brought against any indemnified party and it shall
notify the indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that the
indemnifying party may wish, to assume the defense thereof, with counsel
reasonably satisfactory to such indemnified party, and after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified
party under this Section 6.9 for any legal or other expense subsequently
incurred by such indemnified party in connection with the defense thereof nor
for any settlement thereof entered into without the consent of the indemnifying
party; provided, however, that (i) if the indemnifying party shall elect
       --------  -------
not to assume the defense of such claim or action or (ii) if the indemnified
party reasonably determines (x) that there may be a conflict between the
positions of the indemnifying party and of the indemnified party in defending
such claim or action or (y) that there may be legal defenses available to such
indemnified party different from or in addition to those available to the
indemnifying party, then separate counsel for the indemnified party shall be
entitled to participate in and conduct the defense, in the case of (i) and
(ii)(x), or such different

                                     -25-
<PAGE>

defenses, in the case of (ii)(y), and the indemnifying party shall be liable for
any reasonable legal or other expenses incurred by the indemnified party in
connection with the defense; provided that the Company shall not be obligated to
pay the reasonable legal expenses of more than one firm of counsel for all
indemnified parties in connection with any matter in respect of which indemnity
is sought hereunder, except to the extent any indemnified party or parties
reasonably shall have concluded that there may be a conflict of interest between
any indemnified parties or legal defenses available to such party or parties
which are not available to the other indemnified parties or to the extent
representation of all indemnified parties by the same counsel is otherwise
inappropriate under applicable standards of professional conduct.
