Agreements or in any certificate or other closing document furnished by the
Seller or any of the Seller's Affiliates, pursuant to this Agreement or any of
the Related Agreements, (iii) the Retained Liabilities, (iv) the failure to
obtain the consent or authorization required for the assignment or novation of
any Contract, (v) the failure to obtain any other consent or other authorization
required in connection with the consummation of this Agreement and the Related
Agreements and the transactions contemplated herein and therein, (vi) the
failure to provide notice or timely notice required of the Seller or any of the

indemnify, defend and hold Buyer Indemnitees harmless against any and all Losses

resulting from, relating to or arising in connection with any claim asserted by
Lucent Technologies or its affiliates (collectively "Lucent") in respect of the
Lucent Claims, provided that if Lucent secures an injunction or other equitable
relief against any Buyer Indemnitee, Seller shall also indemnify, defend and
hold such Buyer Indemnitee harmless against any and all special, incidental and
consequential damages in respect thereof.

         Seller shall assume and conduct the defense of each claim in respect of
the Lucent Claims and shall have exclusive control of the defense of each such

records, materials and other information relating to such claims which is under
Buyer's control. Seller shall keep Buyer informed, on request, of the progress
of such defense and negotiations relating to settlement of such claims. Seller
shall not settle or compromise any such claim or make any admission of liability
which provides for or would result in injunctive or equitable relief against the
Buyer without the Buyer's express prior written consent.

         Seller shall not be liable for any infringement that would not occur
but for a modification by Buyer of products which are the subject of the Lucent
Claims, except to the extent that such modification is based on work in progress
obtained by Buyer as part of the Purchased Assets.

         The Seller's indemnity obligation under this Section 13.01(b) does not

<PAGE>   33
Related Agreements or in any certificate or other closing document furnished by
the Buyer or any of the Buyers' Affiliates pursuant to this Agreement or any of

Affiliates after the Closing, or (f) any patent infringement claim following the

         13.03 LIMITS ON INDEMNIFICATION.

         (a) The Seller shall not be liable under the terms and provisions of
this Article 13 unless and until the aggregate amount of liability for
indemnification claims made by the Buyer Indemnitees exceeds twenty thousand
dollars ($20,000) (the "Buyer Liability Basket") at which time the Seller shall
be liable for the full amount (including the amount of the Buyer Liability
Basket) of all indemnification claims made by the Buyer Indemnitees up to an
aggregate amount of two million dollars ($2,000,000); provided, that the
aggregate amount of all claims excluding the Lucent Claims which the Seller
shall be liable for is one million dollars ($1,000,000) (the "Buyer Liability
Cap"). The Buyer Liability Basket and the Buyer Liability Cap set forth in this
Section 13.03(a) shall not apply in the event of fraud, in which case the Buyer
Indemnitees shall be entitled to indemnification on a dollar for dollar basis
for the full amount of the Loss. The Buyer Liability Basket shall not apply to
any indemnification claim made by any of the Buyer Indemnitees with respect to
the Lucent Claims. Further, in the event any settlement payments are made in
connection with the Lucent Claims, including, without limitation, any fees,
expenses and charges under a license agreement (all of such amounts which shall
be paid by the Seller), the prorated amount of the aggregate fees, expenses and
charges attributable to the period prior to the Closing shall not be counted
against the Buyer Liability Cap.

The Buyer shall not be liable under the terms and provisions of this Article 13
unless and until the aggregate amount of liability under Article 13 for
indemnification claims made by the Seller Indemnitees exceeds ten thousand
dollars ($10,000) (the "Seller Liability Basket"), at which time the Buyer shall
be liable for the full amount (including the amount of the Seller Liability
Basket) of all indemnification claims made by the Seller Indemnitees up to an
aggregate amount of one million dollars ($1,000,000) (the "Seller Liability
Cap"). The Seller Liability Basket and Seller Liability Cap set forth in this
Section 13.03(b) shall not apply in the event of fraud in which case the Seller
Indemnitees shall be entitled to indemnification on a dollar for dollar basis
for the full amount of the Loss.

         (b) The amount of any indemnified loss suffered by any Buyer Indemnitee
or Seller Indemnitee shall be reduced by the net effect of any tax-related
benefits related to the claim and/or insurance coverage and/or claim against a
third party which is realized by such indemnified party following the date of
such loss in respect of or as a result of such indemnified loss. Notwithstanding
the foregoing, it is understood and agreed that the determination of the net tax
effect and/or insurance coverage benefit of any indemnified loss and/or third
party claim, if any, shall not delay payment or indemnification of such
indemnified loss by the indemnifying party.

         (c) Apart from (i) the Lucent Claims, (ii) any claim with respect to a
breach of Section 6.12(e) of this Agreement, or (iii) any patent infringement
claim to the extent covered by Section 13.01(a)(viii), neither the Seller nor
any of the Sellers' Affiliates shall be liable to the Buyer

                                      222
<PAGE>   34
Indemnitees under the terms and provisions of this Article 13 in respect of any
patent infringement claim following the Closing.

         (d) PROCEDURES FOR CLAIMS.

                  A Buyer Indemnitee or Seller Indemnitee shall provide written
notice of any indemnification claim under Article 12 (excluding all Lucent
Claims other than any claim in respect of the Lucent Claims asserted against
Buyer after the Closing Date) to the indemnifying party within ten (10) business
days of such party becoming aware of the existence of such indemnification
claim, stating the amount claimed to be due and payable, the basis of the claim
and the provision(s) of the Agreement under which such claim is asserted.
Failure to give notice as required in this Section 13.03 shall not affect the
indemnification obligations of the indemnifying party except to the extent the
indemnifying party can demonstrate such failure materially prejudiced such
party's ability to successfully defend the matter giving rise to the claim.

         13.04 THIRD PARTY CLAIMS.

         (a) Upon the assertion of any claim against a Buyer Indemnitee or a
Seller Indemnitee for which the indemnifying party may be responsible under this
Agreement (each, a "Third Party Claim") the indemnifying party shall have the
right, exercisable by written notice to the Buyer Indemnitee or Seller
Indemnitee, to assume and conduct the defense of each Third Party Claim with
counsel selected by the indemnifying party. If the indemnifying party does
assume and conduct the defense of a Third Party Claim, the Buyer Indemnitee or
Seller Indemnitee shall cooperate and make reasonably available to the
indemnifying party, without cost, all witnesses, pertinent records, materials
and information relating to the Third Party Claim and under such indemnitee's
control.

         (b) If the indemnifying party does not assume the defense of such Third
Party Claim in accordance with this Section 13.04, then the Buyer Indemnitee or
Seller Indemnitee may continue to defend the Third Party Claim. If the
indemnifying party does assume the defense of a Third Party Claim, then the
indemnifying party shall not be liable for any legal expenses subsequently
incurred by the Buyer Indemnitee or Seller Indemnitee in connection with the
defense thereof. However, the Buyer Indemnitee or Seller Indemnitee may assume
its own defense and the indemnifying party shall be liable for all reasonable
costs or expenses paid or incurred in connection therewith, upon the
indemnifying party's failure to defend diligently the Third Party Claim, and the
provision of notice from the Buyer Indemnitee or Seller Indemnitee to the
indemnifying party with regard thereto.

         (c) Without the prior written consent or authorization, which consent
or authorization will not be unreasonably withheld, the indemnifying party shall
not consent to a settlement of, or entry of any judgment arising from any Third
Party Claim which does not include as a term thereof the giving by the claimant
to the Buyer Indemnitee or Seller Indemnitee of a release from all liability in
respect of such Third Party Claim. If the Buyer Indemnitee or Seller Indemnitee
defends the Third Party Claim, the Buyer Indemnitee or Seller Indemnitee may
defend and settle such claim or litigation, after giving notice to the
indemnifying party, on such terms as the indemnified party may deem appropriate.

         (d) The terms of this Section 13.04 shall not apply to any claim in
respect of the Lucent Claims.

         13.05 DISCLOSURES. The Buyer shall not be entitled to claim that any
fact or combination of facts constitutes a breach of any of the representations,
warranties, covenants and agreements in this Agreement to the extent that such
fact or combination of facts has been disclosed in the Disclosure Schedules or
is apparent from any document which is expressly identified in the Disclosure
Schedule and delivered therewith.

         13.06 ENTIRE AGREEMENT. Neither the Buyer nor the Seller have relied on
any representation, warranty or covenant of the other Party or any other person
except as expressly set

                                      223
<PAGE>   35
forth in this Agreement, any of the Related Agreements or in any certificate or
closing document furnished by either Party pursuant to this Agreement or any of
the Related Agreements. No representation, warranty or covenant which is not
contained in this Agreement, any of the Related Agreements, or any certificate
or closing document furnished pursuant to this Agreement or any of the Related
Agreements shall give rise to any liability under this Agreement or any of the
Related Agreements.

         13.07 KNOWLEDGE, SEARCHES AND JOINT MANAGEMENT. The Buyer shall not be
entitled to claim that any fact or combination of facts constitute a breach of
any of the representations, warranties, covenants and agreements in this
Agreement and thereby assert a claim under this Article 13, to the extent that
such fact or combination of facts (a) is within the actual knowledge of Ron
Gaboury and David Ireland of the Buyer and/or (b) is revealed by the searches or
investigations carried out by the Buyer's attorney as listed and attached at
Schedule 13.07, and/or (c) arises out of or results from any act or omission of
the Buyer during the Buyer's joint management of the Business for the period
from May 2, 2000 to June 30, 2000 which amounts to a breach of the joint
management agreement dated 4 May, 2000 between the parties, and/or (d) arises
out of or results from the willful misconduct or gross negligence of the Buyer
during the Buyer's consultancy with the Business for the period from July 1,
2000 to August 31, 2000 which amounts to a breach of the consultancy letter
agreement dated August 1, 2000 between the Parties.

         13.08 SUBJECT TO THE AGREEMENT . The Buyer and the Seller acknowledge
and agree that the representations, warranties, covenants and agreements in this
Agreement are given subject to the Agreement, the Related Agreements and all
