Calculation"). The 12/31/02 Net Book Value Calculation shall become final and
binding upon the parties unless within seven (7) days following submission to
the Principal Securityholder, the Principal Securityholder notifies SCT of his
objection thereto in writing, providing reasonable specificity as to the basis
for his objection. If the Principal Securityholder so notifies SCT of his
objection to the 12/31/01 Net Book Value Calculation, the Principal
Securityholder and SCT shall negotiate in good faith to resolve any differences.
If, within 30 days following the receipt of such notice by SCT, any of such
differences have not been resolved, they shall be resolved by the Auditors and

as reasonably practicable thereafter and the resulting 12/31/01 Net Book Value
Calculation, as reflecting any modifications recommended by the Auditors in

Agreement, shall be final, binding and not subject to any appeal. The fees and
expenses of the Auditors in connection with any such resolution shall be paid by
the Securityholders, pro rata, if the 12/31/01 Net Book Value Calculation is not
modified or is reduced as a result of the Auditors' special purpose audit, or by
SCT, if the 12/31/01 Net Book Value Calculation is increased as a result of the
Auditors' special purpose audit.

and such number is greater than negative Two Hundred Thousand Dollars
(-$200,000), then the Securityholders shall pay, on a pro rata basis, such
difference to SCT (the "Merger Consideration Adjustment") as follows:

                          (i) If the Merger Consideration Adjustment is greater
than the aggregate value of the Escrow Amount,

                              (A) the Merger Consideration Adjustment shall
first be paid from the Escrow Amount on a pro rata basis until the Escrow Amount
is reduced to zero, then

                              (B) the Securityholders shall pay to SCT the
remaining portion of the Merger Consideration Adjustment in cash by wire
transfer of immediately available funds; or

                          (ii) If the Merger Consideration Adjustment is equal
to or less than the aggregate value of the Escrow Amount, the Merger
Consideration Adjustment shall be paid from the Escrow Amount on a pro rata
basis until the Merger Consideration Adjustment is paid in full.

                     (c) The payments in respect of the Merger Consideration
Adjustment, if any, shall be made to SCT on the later of (such later date, the
"Adjustment Payment Date") (A) the date that the Principal Securityholder and
SCT agree on the 12/31/01 Net Book Value Calculation or (B) the date that the
12/31/01 Net Book Value Calculation becomes final and binding upon the parties
in accordance with this Section 2.4.

              4.11.3. No third party that has licensed any Intellectual Property
to ABT has ownership rights or license rights to improvements made by or for ABT
in such Intellectual Property.

Property developed by or for ABT was conceived, reduced to practice, reduced to
tangible form, written or otherwise created solely by employees of ABT. To the
extent that any Intellectual Property has been developed or created
independently or jointly by any person other than ABT or its employees, ABT has
a written agreement with such person with respect thereto, and ABT thereby has
obtained ownership of, and is the exclusive owner of, such Intellectual Property
therein by operation of law or by valid and enforceable assignment or other
agreement. Any such assignment or agreement was and is sufficient to irrevocably
transfer all rights in such Intellectual Property (including the right to seek
past and future damages with respect thereto) to ABT and, to the maximum extent
provided for by, and in accordance with, applicable Laws, ABT has recorded each
such assignment with the relevant governmental authorities, including without
limitation the U.S. Patent and Trademark Office, the U.S. Copyright Office, and
their respective equivalents in any relevant foreign jurisdiction.

              4.11.6. No Securityholder or director, officer, employee
(including both current and former employees), consultant (including both
current and former consultants) or independent contractor (including both
current and former independent contractors) of ABT or any Affiliate of ABT owns,
directly or indirectly, in whole or in part, any Intellectual Property, nor has
any such person asserted any claim of ownership of, or interest in, the
Intellectual Property. No Affiliate of ABT has asserted or may assert any claim
of ownership of, or interest in, the Intellectual Property.

              4.11.7. ABT has taken all reasonable steps that are required to
protect ABT's rights in the Intellectual Property, including without limitation

secrets of ABT.

              4.11.8. The business operations of ABT as currently conducted or
as currently contemplated to be conducted and the Intellectual Property do not
and will not infringe, dilute, misappropriate or otherwise violate the
Proprietary Rights of any third party, and no claim is pending or has been made,
notice given, or dispute arisen to that effect. No third party is infringing or
misappropriating any Proprietary Rights of ABT. With respect to the infringement
or misappropriation by ABT of the Proprietary Rights of any third party, ABT has
not agreed to, or assumed, any obligation or duty to warrant, indemnify,
reimburse, hold harmless, guaranty or otherwise assume or incur any obligation
or liability or provide a right of rescission.

              4.11.9. ABT owns all right, title and interest in and to all of
the Intellectual Property, including, without limitation, all derivative works
and modifications thereto, listed in SCHEDULE 4.11.1, and all such Intellectual
Property is valid and in full force, is held of record in the name of ABT free
and clear of all Liens other than Permitted Liens, and is not the subject of any
cancellation or reexamination proceeding or any other proceeding or outstanding
decree, order, judgment or settlement agreement or stipulation that restricts in
any manner the use, transfer or licensing thereof by ABT or may affect the
validity, use or enforceability of the Intellectual Property. ABT is the
applicant of record in all patent applications, and applications for trademark,
service mark, trade dress, industrial design, copyright and mask work
registration indicated in SCHEDULE 4.11.1, and no opposition, extension of time
to oppose, interference, rejection, or refusal to register has been received in

Intellectual Property. No current or former employee, consultant or independent

performing services for ABT.

to Intellectual Property to which ABT is a party. Following the Closing, except
as set forth on SCHEDULE 4.11.12(2), SCT and/or any of its Affiliates will be
permitted to exercise all of ABT's rights under such Contracts to the same
extent ABT would have been able had the Transactions not occurred, and without
the payment of any additional amounts or consideration other than ongoing fees,
royalties or payments which ABT would otherwise be required to pay.

              4.11.13. Neither this Agreement nor the Transactions will result
in (i) SCT or any of its Affiliates granting to any third party any right to or
with respect to any Intellectual Property owned by, or licensed to, either of
them, including without limitation the release of any source code from any
escrow, or (ii) SCT or any of its Affiliates being bound by, or subject to, any
non-compete or other restriction on the operation or scope of its current and
future businesses.

              4.11.14. No (i) product, technology, service or publication of
ABT, (ii) material published or distributed by ABT, or (iii) conduct or
statement of ABT, constitutes a defamatory statement or, to the knowledge of ABT

         10.4. Procedure for Claims.

              10.4.1. An Indemnified SCT Party or an Indemnified ABT Party that
desires to seek indemnification under any part of this Section 10 (each, an
"Indemnified Party") shall give notice (a "Claim Notice") to each party
responsible or alleged to be responsible for indemnification hereunder (an
"Indemnitor") prior to any applicable Expiration Date specified below. Such
notice shall briefly explain the nature of the claim and the parties known to be
involved, and shall specify the amount thereof. If the matter to which a claim
relates shall not have been resolved as of the date of the Claim Notice, the
Indemnified Party shall estimate the amount of the claim in the Claim Notice,
but also specify therein that the claim has not yet been liquidated (an
"Unliquidated Claim"). If an Indemnified Party gives a Claim Notice for an
Unliquidated Claim, the Indemnified Party shall also give a second Claim Notice
(the "Liquidated Claim Notice") within 60 days after the matter giving rise to
the claim becomes finally resolved, and the Liquidated Claim Notice shall
specify the amount of the claim. Each Indemnitor to which a Claim Notice is
given shall respond to any Indemnified Party that has given a Claim Notice (a
"Claim Response") within 20 days (the "Response Period") after the later of (i)
the date that the Claim Notice is given and (ii) if a Claim Notice is first
given with respect to an Unliquidated Claim, the date on which the Liquidated
Claim Notice is given. Any Claim Notice or Claim Response shall be given in
accordance with the notice requirements hereunder, and any Claim Response shall
specify whether or not the Indemnitor giving the Claim Response disputes the
claim described in the Claim Notice. If any Indemnitor fails to give a Claim
Response within the Response Period, such Indemnitor shall be deemed not to
dispute the claim described in the related Claim Notice. If any Indemnitor
elects not to dispute a claim described in a Claim Notice, whether by failing to
give a timely Claim Response or otherwise, then the amount of such claim shall
be conclusively deemed to be an obligation of such Indemnitor.

                                      -46-
<PAGE>

              10.4.2. If any Indemnitor shall be obligated to indemnify an
Indemnified Party hereunder, such Indemnitor shall pay to such Indemnified Party
within 30 days after the last day of the Response Period the amount to which
such Indemnified Party shall be entitled. If there shall be a dispute as to the
amount or manner of indemnification under this Section 10, the Indemnified Party
may pursue whatever legal remedies may be available for recovery of the Damages
claimed from any Indemnitor, but any dispute shall be resolved in accordance
with Section 12.6 to the extent that it may be applicable. If any Indemnitor
fails to pay all or part of any indemnification obligation when due, then such
Indemnitor shall also be obligated to pay to the applicable Indemnified Party
interest on the unpaid amount for each day during which the obligation remains
unpaid at an annual rate equal to the Prime Rate, and the Prime Rate in effect
on the first Business Day of each calendar quarter shall apply to the amount of
the unpaid obligation during such calendar quarter.

              10.4.3. Notwithstanding any other provision of this Section 10,
except as set forth below in this Section and with respect to the provisions
regarding a Merger Consideration Adjustment in Section 2.4, an Indemnified Party
shall be entitled to indemnification with respect to inaccuracy of any
representation or warranty made hereunder only when the aggregate of all Damages
to such Indemnified Party exceeds One Hundred Fifty Thousand Dollars ($150,000)
(the "Threshold Amount") and then such Indemnified Party shall be entitled to
indemnification for all of its Damages, including the Damages counted in
achieving the Threshold Amount. In addition, the calculation of the Threshold
Amount shall include any Damages incurred by an Indemnified Party for which the
Indemnified Party would have been entitled to claim indemnification under this
Section 10 with respect to a breach of representation or warranty but for such
representation or warranty being qualified by materiality or the knowledge of a
particular party. Notwithstanding the preceding, the Threshold Amount shall not
apply with respect to inaccuracy of the representations and warranties in
Sections 4.3.1, 4.3.2, 4.3.3, 4.3.4, 4.4.1, 4.4.2. and 4.9. In no event shall an
Indemnitor be obligated to indemnify an Indemnified SCT Party or an Indemnified
ABT Party, as the case may be, under this Section 10 for amounts in excess of
the Merger Consideration (the "Cap"). Any amounts payable as a Merger
Consideration Adjustment shall be deducted from the Cap.

<PAGE>

              10.4.4. In calculating any indemnification payment required to be
made pursuant to this Section 10, the amount of such payment shall be increased
by the amount of any additional Tax cost incurred by Indemnified Party as a
result of the receipt of such payment (including any additional amounts received
pursuant to the foregoing) and reduced by the amount of any Tax benefit actually
realized by the Indemnified Party in respect of the matter for which
indemnification is claimed.

         10.5. Claims Period. Any claim for indemnification under this Section
10 shall be made by giving a Claim Notice under Section 10.4 on or before the
applicable "Expiration Date" specified below in this Section 10.5, or the claim
under this Section shall be invalid. "Expiration Date" means:

              10.5.1. the date on which the applicable statute of limitations
expires with respect to any claim for Damages related to (i) a breach of any
covenant or agreement to be performed at least in part after the Closing Date,
or (ii) a breach of any representations or warranties of a party to this
Agreement that were untrue when made with an actual intent to mislead or
defraud;

              10.5.2. for any breach of a representation or warranty set forth
in Sections 4.3, 4.4 or 4.14, indefinitely;

              10.5.3. for any breach of a representation or warranty set forth
in Sections 4.9, 4.24, 4.27, 4.30 or 4.34, for 60 days after the expiration of

So long as an Indemnified Party gives a Claim Notice for an Unliquidated Claim
on or before the applicable Expiration Date, such Indemnified Party shall be
entitled to pursue its rights to indemnification regardless of the date on which
such Indemnified Party gives the related Liquidated Claim Notice.

         10.6. Third Party Claims. An Indemnified Party that desires to seek
indemnification under any part of this Section 10 with respect to any actions,
suits or other administrative or judicial proceedings (each, an "Action") that
may be instituted by a third party shall give each Indemnitor prompt notice of a
third party's institution of such Action. After such notice, any Indemnitor may,
or if so requested by such Indemnified Party, any Indemnitor shall, participate
in such Action or assume the defense thereof, with counsel satisfactory to such
Indemnified Party; provided, however, that such Indemnified Party shall have the
right to participate at its own expense in the defense of such Action; and
provided, further, that the Indemnitor shall not consent to the entry of any
judgment or enter into any settlement, except with the written consent of such
Indemnified Party (which consent shall not be unreasonably withheld). Any
failure to give prompt notice under this Section 10.6 shall not bar an
Indemnified Party's right to claim indemnification under this Section 10, except
to the extent that an Indemnitor shall have been materially harmed by such
failure.

to the other party of its intent to do so. Neither party shall be precluded
