Arbiter and not by independent review) only those items in dispute and shall
render a report as to its resolution of such items and the resulting calculation

the Arbiter's determination, the amounts to be included shall be the appropriate
amounts from the Closing Date Asset Detail or the Adjustment Report, as the case
may be, as to items that are not in dispute, and the amounts determined by the
Arbiter, as to items that are submitted for resolution by the Arbiter. In
resolving any disputed item, the Arbiter may not assign a value to such item
greater than the greatest value for such item claimed by either party or less
than the lowest value for such item claimed by either party. Buyer and Seller
shall cooperate with the Arbiter in making its determination and such
determination shall be conclusive and binding upon Buyer and Seller. Buyer and
Seller shall each bear one-half of the fees and expenses of the Arbiter.

Within five Business Days after the final determination of the Net Asset
Adjustment in accordance with this Section 4.4: either (x) Buyer shall pay
Seller by wire transfer of immediately available funds the amount, if any, by
which the Final Net Asset Adjustment is greater than zero; or (y) Seller shall
pay Buyer by wire transfer of immediately available funds the amount, if any, by
which the Final Net Asset Adjustment is less than zero.

in equity, to an injunction enjoining and restraining Seller from doing or
continuing to do any such violation and any other violations or threatened
violations of this Section.

Seller acknowledges and agrees that the covenants set forth in this Section are
reasonable and valid in scope and in all other respects. If any of such
covenants is found to be invalid or unenforceable by a final determination of a
court of competent jurisdiction (i) the remaining terms and provisions hereof
shall be unimpaired and (ii) the invalid or unenforceable term or provision
shall be deemed replaced by a term or provision that is valid and enforceable
and that comes closest to expressing the intention of the invalid or
unenforceable term or provision.

TAXES. Seller shall, to the extent that failure to do so could adversely affect
the Assets following Closing: (i) continue to file within the required time
period for filing all returns and reports relating to Taxes required to be filed
by Seller, and such returns and reports shall be true, correct and complete; and
(ii) be responsible for and pay when due any and all Taxes attributable to,
levied or imposed upon the Assets for periods (or portions thereof) ending on or
prior to the Closing.

POST-CLOSING COOPERATION. Seller agrees that, if requested by Buyer, it will
cooperate with Buyer in enforcing the terms of any agreements between Seller and
any third party involving the Assets, including without limitation terms
relating to the protection of intellectual property rights. In the event that
Buyer is unable to enforce its intellectual property rights against a third
party as a result of a rule or law barring enforcement of such rights by a
transferee of such rights, Seller agrees to reasonably cooperate with Buyer by
assigning to Buyer such rights as may be required by Buyer to enforce its
intellectual property rights in its own name.

NO DISTRIBUTION OF PRODUCTS. All distribution agreements under which Seller has
granted a right to resell or otherwise distribute the products, including a
brief description of the termination provisions of each such agreement, are
listed in Schedule 1. Indemnification.

SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The representations and warranties
of Seller in Section 7 shall survive for a period one year after the Closing
Date, except for claims for fraud, which shall survive indefinitely, and claims
for Taxes, which shall survive until lapse of the applicable statute of
limitations (including extensions thereof). No investigation, or knowledge
acquired, by Buyer or on behalf of Buyer with respect to any breach of any
representation or warranty made by Sellers or any other matter shall affect
Buyer's rights to indemnification pursuant to this Section 10.

INDEMNIFICATION BY SELLER. Seller shall indemnify and hold harmless Buyer, each
direct and indirect subsidiary of Buyer and each of their officers, directors,
employees, agents, successors and assigns ("BUYER INDEMNITEES") for any and all



liabilities, losses, damages, claims, costs and expenses, interest, awards,
judgments and penalties (including, without limitation, legal costs and expenses
and interest on the amount of any loss from the date suffered or incurred by
Buyer Indemnitee) (a "LOSS") arising out of, resulting from or caused by: (i)
any breach or the inaccuracy of any of the representations, warranties,
covenants, or agreements in this Agreement made by Seller, and (ii) all
liabilities or obligations, including, without limitation, those relating to
Taxes, (whether known or unknown, accrued or not accrued, fixed or contingent)
of Seller existing at Closing. The obligation of Seller to indemnify Buyer under
this Section 10.2 shall not be limited in time or amount; provided that (except
in the case of fraud by Seller and claims for Taxes) the aggregate liability for
claims made solely for breaches of representations and warranties under Section
10.4(a) shall not exceed the Purchase Price, and the indemnification obligations
relating to such claims shall terminate one (1) year from the date of this
Agreement. Without limiting the generality or effect of the foregoing, Seller
shall indemnify, defend and hold harmless Buyer and each of its Affiliates (as
defined in Rule 501 under the Securities Act of 1933, as amended) from and
against any and all Loss resulting from or arising out of any of the following:

(i) any liability to any Employee as of the Closing Date arising in connection
with their employment by Seller, including, without limitation, post-retirement
health benefits, to the extent not fully funded immediately prior to the
Closing, and (ii) any severance or other benefit payable to any Employee by
reason of this Agreement or the transactions contemplated hereby, including,
without limitation, any stay bonus, golden parachute or other change-in-control
payment or benefit;

Any claim or liability resulting from or in connection with Seller having failed
to obtain, prior to the Closing Date, the approval of its shareholders for any
of the transactions contemplated by this Agreement or any other document
contemplated herein; or

Any claim or liability resulting from or in connection with Seller's breach,
prior to the Closing Date, of the terms of any license agreement or Seller's
failure to obtain a license for Seller's use of any software incorporated into a
Product prior to the Closing Date.

INDEMNIFICATION BY BUYER. Buyer shall indemnify and hold harmless Seller
("SELLER INDEMNITEES") for any and all Losses arising out of or resulting from a
liability or obligation, including, without limitation, those relating to Taxes,
(whether known or unknown, accrued or not accrued, fixed and determined or
contingent) of Buyer arising out of or resulting from the use or sale of the
Assets by Buyer after the Closing Date, other than a liability or obligation for
which any Buyer Indemnitee is entitled to indemnification from Seller pursuant
to the provisions of Section 10.2. Buyer's obligation to indemnify Seller under
this Section 10.3 shall not be limited in time or amount.

INDEMNIFICATION PROCEDURE.
Whenever any Loss shall be asserted against or incurred by a Buyer Indemnitee or
Seller Indemnitee (the "INDEMNIFIED PARTY"), the Indemnified Party shall give
written notice thereof (a "CLAIM") to Seller or Buyer, respectively (the
"INDEMNIFYING PARTY"). The Indemnified Party shall furnish to the Indemnifying
Party in reasonable detail such information as the Indemnified Party may have
with respect to the Claim (including in any case copies of any summons,
complaint or other pleading which may have been served on it and any written
claim, demand, invoice, billing or other document evidencing or asserting the
same). The failure to give such notice shall not relieve the Indemnifying Party
of its indemnification obligations under this Agreement.

If the Claim is based on a claim of a person that is not a party to this
Agreement, the Indemnifying Party shall, at its expense, undertake the defense
of such Claim with attorneys of its own choosing reasonably satisfactory to the
Indemnified Party. In the event the Indemnifying Party, within a reasonable time
after receiving notice of a Claim from the Indemnified Party, fails to defend
the Claim, the Indemnified Party may, at the Indemnifying Party's expense,
undertake the defense of the Claim and may compromise or settle the Claim, all
for the account of the Indemnifying Party. After notice from the Indemnifying
Party to the Indemnified Party of its election to assume the defense of such
Claim, the Indemnifying Party shall not be liable to the Indemnified Party under
this Section 10.4 for any legal expenses subsequently incurred by the
Indemnified Party in connection with the defense thereof, except for such
expenses incurred in connection with cooperation with, or at the request of, the
Indemnifying Party; provided, however, that the Indemnified Party shall have the
right to employ counsel to represent it if, in the Indemnified Party's
reasonable judgment, based upon the advice of counsel, it is advisable, in light
of the separate interests of the Indemnified Party and the Indemnifying Party,
for the Indemnified Party to be represented by separate counsel, and in that
event the reasonable fees and expenses of such separate counsel shall be paid by
the Indemnifying Party.

The Indemnifying Party shall not, except with the consent of the Indemnified
Party, given in its sole discretion, consent to entry of any judgment or enter
into any settlement.

General Terms.

NOTICES. Every notice or other communication required or contemplated by this
Agreement by either party shall be delivered to the other party at the address
first set forth above by: (i) personal delivery; (ii) postage prepaid, return
receipt requested, registered or certified mail; (iii) internationally
recognized express courier, such as Federal Express, UPS or DHL; or (iv)
facsimile or email with a confirmation copy sent simultaneously by postal mail.
Notice not given in writing shall be effective only if acknowledged in writing
by a duly authorized representative of the party to whom it was given.




SEVERABILITY. In the event any provision of this Agreement shall be determined
to be invalid or unenforceable under applicable law, all other provisions of
this Agreement shall continue in full force and effect unless such invalidity or
unenforceability causes substantial deviation from the underlying intent of the
parties expressed in this Agreement or unless the invalid or unenforceable
provisions comprise an integral part of, or are inseparable from, the remainder
of this Agreement. If this Agreement continues in full force and effect as
provided above, the parties shall replace the invalid provision with a valid
provision which corresponds as far as possible to the spirit and purpose of the
invalid provision.

AMENDMENTS AND WAIVERS. No amendment, modification, termination or waiver of any
provision of this Agreement or consent to any departure by any party therefrom
shall in any event be effective without the written concurrence of the other
party hereto. Any waiver or consent shall be effective only in the specific
instance and for the specific purpose for which it is given. No notice to or
demand on any party in any case shall entitle any other party to any other or
further notice or demand in similar or other circumstances.

ABSENCE OF THIRD-PARTY BENEFICIARIES. No provisions of this Agreement, express
or implied, are intended or shall be construed to confer upon or give to any
Person other than the parties hereto, any rights, remedies or other benefits
under or by reason of this Agreement unless specifically provided otherwise
herein, and except as so provided, all provisions hereof shall be personal
solely between the parties to this Agreement.

GOVERNING LAW. The validity, construction, performance and enforceability of
this Agreement shall be governed in all respects by the laws of the State of
California, without reference to the choice-of-law principles thereof.

INTERPRETATION. This Agreement, including any exhibits, addenda, schedules and
amendments, has been negotiated at arm's length and between persons
sophisticated and knowledgeable in the matters dealt with in this Agreement. The
provisions of this Agreement shall be interpreted in a reasonable manner to
effect the purposes of the parties and this Agreement. The article and section
headings contained in this Agreement are for reference purposes only and will
not affect in any way the meaning or interpretation of this Agreement.

ENTIRE AGREEMENT. The terms of this Agreement and the other writings referred to

final expression of their agreement with respect to the subject matter hereof
and may not be contradicted by evidence of any prior or contemporaneous
agreement. The parties further intend that this Agreement, together with the

statement of its terms. The parties acknowledge and agree that this Agreement
and exhibits and schedules hereto constitute the agreements necessary to
accomplish the transactions contemplated by this Agreement and are parts of an
integrated arrangement between the parties with respect to the purchase and sale
of the Assets.

COUNTERPARTS. This Agreement may be executed simultaneously in multiple
counterparts, each of which shall be deemed an original, but all of which taken
together shall constitute one and the same instrument. Execution and delivery of
this Agreement by exchange of facsimile copies bearing the facsimile signature
of a party hereto shall constitute a valid and binding execution and delivery of
this Agreement by such party. Such facsimile copies shall constitute enforceable
original documents.

EXPENSES. Each of the parties agrees to pay its own expenses in connection with
the transactions contemplated by this Agreement, including without limitation
legal, consulting, accounting and investment banking fees, whether or not such
transactions are consummated.
