Specific Project Agreement or Order. All provisions of this SA shall apply to
all Specific Project Agreements entered into or Orders placed by any Ordering
Company.

     5.2 Any reference herein to Company shall be deemed to refer to the
applicable Ordering Company (to the extent applicable to a SPA entered into or
an Order placed by an Ordering Company other than Company).

     ARTICLE 6 - SPECIFIC PROJECT AGREEMENTS AND ORDERS

     6.1 (a) The parties hereto contemplate that Specific Project Agreements
("SPA") may be entered into by Company or by an Ordering Company incorporating
by reference the terms and conditions of this Agreement. The parties hereto also
contemplate that Purchase Orders ("Order" or "Orders") may be placed from time
to time by Company or Ordering Companies incorporating by reference the terms
and conditions of this Agreement or, if applicable, a designated SPA.

          (b) Each such SPA and/or Order shall set forth the terms and
     conditions reflecting business requirements unique to a particular Ordering
     Company. Should there be a conflict between the terms of this Agreement and
     the terms of a SPA, the terms of the SPA shall prevail, but shall not
     otherwise modify this Agreement. If there is a conflict between the terms
     of this Agreement and the terms of an accepted Order, the terms of the
     Order shall prevail, but shall not otherwise modify this Agreement; however
     in no event shall the pre-printed terms and conditions contained on
     Company's Order(s) supplement or supersede this Agreement or any relevant
     SPA(s).

          (c) Notwithstanding any other provision of this Agreement, a SPA
     entered into or an Order placed by an international Ordering Company on
     Supplier may include terms and conditions relating to specific commercial,
     legal, and regulatory requirements particular to that country. Such terms
     and conditions would prevail for the SPA or Order upon mutual agreement of
     the parties, but shall not otherwise modify this Agreement.

     ARTICLE 7 - ENTIRE AGREEMENT

     7.1 This Agreement shall incorporate the provisions of any SPA issued
pursuant to this Agreement and the typed or written provisions on Company's
Orders issued pursuant to this Agreement and accepted by Supplier which specify
supplemental terms consistent with this Agreement relating to delivery, quantity

excluding any pre-printed provisions and shall constitute the entire agreement
between the parties with respect to the subject matter of this Agreement. Such
SPA(s) and Order(s) shall not be modified or rescinded, except by a writing
signed by Supplier and Company. Printed provisions on the reverse side of
Company's Orders (except as specified otherwise in this Agreement) and all
provisions on Supplier's forms shall be deemed deleted. Estimates or forecasts
furnished by Company shall not constitute commitments except as specified
elsewhere in this Agreement. The provisions of this Agreement supersede all
contemporaneous oral

the parties with respect to the subject matter of this Agreement, provided that
the Supply Agreement is subordinate to Purchase Agreement and the Intellectual
Property Agreement in the event of conflict.

     7.2 This Agreement may be modified by agreement of both of the parties in a
written amendment ("Amendment") and such Amendment shall constitute part of this
Agreement according to its terms.

     ARTICLE 8 - SPECIFICATIONS, DRAWINGS, CHANGES & DISCONTINUANCE

performance characteristics and description, all provisions contained in such
Specifications or Supplier Specifications shall be deemed deleted.

     8.2 In accordance with the notification procedures specified in Article 37,
NOTICES, Supplier shall provide Company with at least ninety (90) days prior
written notice of any change to form, fit or function proposed to be made by
Supplier to the Specifications or Supplier Specifications of the Equipment,
Materials, and/or Software furnished under this Agreement excluding changes for
health or safety reasons, to comply with governmental regulations or to conform
to applicable standards, which changes may be made immediately without prior
written notice. All such changes must be backward compatible and provide equal
or superior performance / features / functionality to the Equipment, Materials,
and/or Software as they existed prior to making of the change. Additionally, all
necessary permits, regulatory approvals (including homologation),
type-acceptance or type-certification, electrical safety agency approvals, etc.
must be obtained by Supplier.

     8.3 Within thirty (30) days after receipt of Supplier's change
notification, Company will provide its written response to Supplier. If Company
fails to provide such written response within such period, Supplier's change
notification shall be deemed accepted. If Company, in its reasonable discretion,
does not agree to the changes proposed by Supplier, and Supplier states that
Supplier cannot continue without such changes, then Supplier shall not
discontinue accepting Orders and supplying Equipment, Materials, and/or Software
that conforms to the previous Specifications or Supplier Specifications, as
applicable, until Supplier and Company have agreed upon a mutually acceptable
transition plan that takes into account Company's existing inventory and the
embedded base of Company's customers of the Equipment, Materials, and/or
Software to be changed. If the parties cannot mutually agree on a transition
plan, then without any cost to or liability of Company, Company shall have the
right to terminate any or all Orders for Equipment, Materials, and/or Software
affected by such changes.

     8.4 If Supplier discontinues manufacture of any Equipment, Materials,
and/or Software covered under this Agreement, Supplier shall provide Company one

however, if Supplier offers replacement Equipment, Materials, and/or Software
which is: (i) backward compatible, (ii) equivalent in form, fit or function,
(iii) provides equal or superior performance/feature/functionality to the
Equipment, Materials, and/or Software as it existed prior to making of the
change and, (iv) has received all necessary permits, regulatory approvals

     ARTICLE 21 - EPIDEMIC CONDITIONS

     21.1 Notwithstanding any other provision of this Agreement, if during the
Term of this Agreement and for one (1) year after the last shipment date of
Equipment and/or Materials under this Agreement, Company notifies Supplier that
Equipment and/or Materials shows evidence of an "Epidemic Condition," Supplier
shall prepare and propose a Corrective Action Plan ("CAP") with respect to such
Equipment and/or Materials within ten (10) working days of such notification,
addressing implementation and procedure milestones for remedying such Epidemic
Condition(s). An extension of this time frame is permissible upon mutual written
agreement of the parties.

     21.2 Upon notification of the Epidemic Condition to Supplier, Company shall
have the right to postpone all or part of the shipments of unshipped Equipment
and/or Materials in the affected category, by giving written notice of such
postponement to Supplier, pending resolution of the Epidemic Condition. Such
postponement shall temporarily relieve Supplier of its shipment liability and
Company of its shipment acceptance liability.

     21.3 Should Supplier not agree to the existence of an Epidemic Condition or
should Company not agree to the CAP, then Company shall have the right to
suspend all or part of its unshipped Orders without liability to Company until
such time as a mutually acceptable solution is reached.

     21.4 An Epidemic Condition will be considered to exist when one or more of
the following conditions occur:

          (a) Failure reports or statistical samplings show one percent (1%) of
     Equipment and/or Materials installed or of Equipment and/or Materials
     shipped during any two (2) consecutive months exhibit a highly
     objectionable symptom (such as emissions of smoke, loud noises, deformation
     of housing) or other disconcerting symptoms of this type.

          (b) Failure reports or statistical sampling show one or more instances
     of Equipment and/or Materials tracked by Company to contain a potential
     safety hazard (such as personal injury or death, fire, explosion, toxic
     emissions, etc.).

          (c) Return rate data indicated that the observed Mean Time Between
     Failures (MTBF) is not meeting the predicted MTBF as set forth in
     Attachment A for each product. Predicted MTBF shall be calculated using one
     of the industry recognized standards as mutually agreed upon by the
     parties. When periodic monitoring of the field data shows that a circuit
     pack's MTBF is not being met, it is required that the supplier report that
     condition. Also at the same time the supplier shall perform a 90%
     confidence interval analysis of the field data and determine if that meets
     the prediction. If not, then this constitutes an Epidemic Condition.

          (d) Equipment and/or Materials Dead on Arrival ("DOA") failures exceed
     one percent (1 %). For the purpose of this Agreement, DOA shall be defined
     as any Equipment and/or Materials that during testing, installation, or
     upon its first use fails to operate in accordance with the Specification.
     Visual / mechanical / appearance DOA is defined as any Equipment and/or
     Materials containing one or more major defects that would make the
     Equipment and/or Materials unfit for use or installation.

     21.5 Only major functional and visual/mechanical/appearance defects are
considered for determining Epidemic Condition. Equipment and/or Materials could
be either sampled or, a Company's option, 100% audited at Company's or
Supplier's warehouses, factories or Company's customers' locations. If Equipment
and/or Materials is sampled, the data must have 95% or better statistical
confidence.

<PAGE>

     21.6 An Epidemic Condition shall not include failures due to Company
supplied design, documentation, or instruction.

     21.7 In the event that Supplier develops a remedy for the defect(s) that
caused the Epidemic Condition and Company agrees in writing that the remedy is
acceptable, Supplier shall:

          (a) Incorporate the remedy in the affected Equipment and/or
     Materials in accordance with the Article 8, SPECIFICATIONS, DRAWINGS,
     CHANGES, & DISCONTINUANCE.

          (b) Ship all subsequent Equipment and/or Materials incorporating the
     required modification correcting the defect(s) at no additional charge to
     Company; and

          (c) Repair and/or replace returned Equipment and/or Materials that
     caused the Epidemic Condition. Supplier shall reimburse Company for all
     reasonable direct costs it incurs for removing and returning such Equipment
     and/or Materials that caused the Epidemic Condition and for re-installing
     such repaired and/or replaced Equipment and/or Materials. Supplier shall
     bear risk of in transit loss and damage for such repaired and/or replaced
     Equipment and/or Materials.

     21.8 Supplier and Company shall mutually agree in writing as to the
remedy's implementation schedule. Supplier shall use commercially reasonable
efforts to implement the remedy in accordance with the agreed-upon schedule.

     21.9 If Supplier is unable to remedy an Epidemic Condition, as reasonably
agreed by the parties in good faith, Company may: (1) develop and implement such
remedy and, in such case, implementation costs and risk of in-transit loss shall
be borne by Supplier, and/or (2) cancel Orders without liability and return all
Equipment and/or Materials within the lot covered by such Epidemic Condition for
full refund, payable by Supplier within thirty (30) days after receipt of
returned Equipment and/or Materials (with risk of loss or in-transit damage
borne by Supplier), and notwithstanding any other provision of this Agreement or
the Asset Purchase Agreement, Company shall be able to obtain functional
equivalents to the affected Equipment or Materials from alternate sources until
such time as Supplier provides a remedy for the Epidemic Condition.

     21.10 Should more than one (1) Epidemic Condition occur in any consecutive
twelve (12) month period for a given product (e.g. MERCURY, SONATA III, etc.),
which Supplier is unable to remedy in accordance with the agreed upon Corrective
Action Plan, then in addition to any other remedies available to it under this
Agreement, Company shall be released from its obligations to Supplier under
Article 3.1(a) for such product for the remainder of the Term of the Agreement
with no liability.

     21.11 Notwithstanding Supplier's obligations pursuant to this Article 21,
Supplier's liability shall not apply to Equipment or Materials acquired from
inventory as of the Effective Date or Equipment and/or Materials manufactured
using Company Specifications and manufacturing processes in effect as of the

          Contract Manufacturer(s); then

     Company shall have the right to obtain the required Equipment and/or
Materials directly from Supplier's Contract Manufacturer(s). Notwithstanding the
foregoing, Company shall have no such rights under this Article 35 (i) if
Supplier's unwillingness or inability to deliver is based on bona fide concerns
about Ordering Company's ability or willingness to make proper payment hereunder
and (ii) until Company shall have followed the Dispute Resolution Process under

manufacture the required Equipment and/or Materials or have the Equipment and/or
Materials manufactured by a third party to satisfy any outstanding requirements
Company has with its customers, until such time as Supplier is able to provide
the required Equipment and/or Materials.

     35.4 If Company exercises its option to either manufacture the required
Equipment and/or Materials or to have the Equipment and/or Materials
manufactured by a third party, Supplier hereby grants to Company a
non-revocable, non-exclusive, royalty-freebearing, non-transferable license
under Supplier's technology and information, and intellectual property rights
therein, necessary for Company, or a third party sublicensee, to manufacture in

     38.2 Senior management of either party may, upon notice and within five (5)
business days of receipt of a notice from the other party elect to utilize a
non-binding resolution procedure whereby each presents its case before a panel
consisting of two senior executives of each of the parties and, if such
executives can agree upon such an individual, a mutually acceptable neutral
advisor. If a party elects to use the procedure set forth in this clause, the
other party shall participate. The hearing shall occur no more than ten (10)
business days after a party serves notice to use the procedure set forth in this
clause. If the matter cannot be resolved by such senior executives, the neutral
advisor, if one has been agreed upon, may be asked to assist such senior

breach of warranty set forth in Article 22, EQUIPMENT AND MATERIALS WARRANTY and
Article 29, SOFTWARE WARRANTY, or otherwise breaches an obligation specified in
this Agreement, the Company shall give notice to the Supplier of the ostensible
performance default, which notice shall explain in reasonable detail the basis
for Company's belief that a performance default has occurred. After receipt of
such notice, Supplier shall respond to Company within fifteen (15) working days
with either (1) a Corrective Action Plan to correct such default condition in a
reasonable time, or (2) an explanation in reasonable detail as to why Supplier
does not believe a performance default has occurred. If Supplier fails to
deliver a Corrective Action Plan or an explanation within the fifteen (15)
working day period, if the Corrective Action Plan or explanation is reasonably
determined to be unacceptable by Company, or if the Corrective Action Plan in
Company's judgment fails to cure the default for such Equipment, Material, or
Software within the specified period, Company may purchase equipment and
material, or license software from a source other than Supplier. In addition,
either party shall have the right to demand review under Article 38, DISPUTE
RESOLUTION. If within 60 days of the original notice by Company, review under
the dispute resolution process does not resolve the dispute and/or Supplier does
not achieve a cure of the performance default, Company may invoke all its rights
under this Agreement. All Default Resolution Process communication shall be
through the contacts specified in Article 37 - NOTICES.

proof satisfactory to Company) and no further Services pursuant to such
terminated Order will be rendered by Supplier. Such payment shall constitute a
full and complete release and discharge of Company's obligations. In no event
shall Company's liability exceed the price identified in the applicable Company
Order for the Services being terminated. Prior to the effective date of
termination, as directed by Company, Supplier will deliver to Company all
completed work, or partially completed work, along with all related supporting
documentation, notes, and other deliverables.

     43.4 Upon termination, Supplier shall promptly return all Information
related to the terminated Order to Company.

     ARTICLE 44 - DELIVERY/SHIPPING INTERVAL /LATE DELIVERY

     44.1 Company intends to monitor Supplier's delivery performance. For the

that delivery time is based on the time the Order is accepted by Supplier until
the time Equipment and/or Materials is delivered to Company's designated carrier
or freight forwarder in accordance with Article 46, SHIPMENT TERMS. Company's
delivery requirement is that Supplier maintains an on-time delivery performance
as stated in Attachment B. In accordance with Attachment K, within 180 days from
the Effective Date, Supplier will establish in good faith the lead times for
on-time delivery performance for forecasted and non-forecasted Equipment and/or
Materials. Article 44.2 shall not govern measurement of on-time delivery
performance versus published lead times until such lead times are established.

either:

               (i) cancel such Order;

               (ii) extend such delivery time frame to a later date, subject,
          however, to the right to cancel as in (i) preceding if delivery is not
          made or performance is not completed on or before such extended
          delivery date;

               (iii) obtain functionally equivalent products from alternate
          sources in order to meet Order requirements; or

               (iv) exercise its rights under Article 35, MANUFACTURING RIGHTS.

          (b) If an Order is canceled by Company pursuant to the above, Company
     shall have the right to retain or return any or all Equipment, Materials
     and/or Software received by or paid for by Company under such Order.

          (c) Within fifteen (15) days of Supplier's receipt of returned
     Equipment, Materials and/or Software, Supplier shall reimburse Company for
     the costs of shipping the Equipment, Materials and/or Software returned to
     Supplier (including customs, duties and taxes) and for any amounts,
     including

<PAGE>

     shipping costs, customs, duties and taxes previously paid by Company for
     the returned Equipment, Materials and/or Software.

          (d) Company shall pay for any Equipment, Materials and/or Software it
     retains at the prices set forth in the Order placed pursuant to this
     Agreement, less any damages, as described in Article 13, COMMITMENT

          (e) In addition to the damages set forth in Article 13 and the terms
     described in this Article 44.2, if Supplier is unable to meet the
     acknowledged delivery date(s)set forth in an accepted Order, Supplier shall
     be responsible for paying all premium transportation costs necessary to
     deliver the requested Equipment, Materials and/or Software to Company by
     the acknowledged delivery date(s) indicated in the Order, subject to the
     provisions of Article 70.

     44.3 Supplier agrees to promptly notify the Company's buyer, as identified
on the Order, of any foreseeable condition that will affect Supplier's ability
to meet the acknowledged shipment date and Company's expected delivery date.
Supplier's compliance with the foregoing will not relieve Supplier of the
delivery performance requirements or other conditions set forth in this Article
44.

     44.4 At Company's request, Supplier shall ship Equipment and/or Materials
directly to Company's End User customer locations.

     ARTICLE 45 - PRODUCT CONFORMANCE REVIEWS

and perform all acts as required for the assignment of the Assigned Software,
Assigned Patents, Assigned Technology and Assigned Marks, including but not
limited to the Intellectual Property Rights that are specific thereto, to

Section 2.05(b)) the Assigned Software, Assigned Technology and Derivative Works
thereof with respect to any products or services of the businesses in which
Lucent or any of its Subsidiaries is now or hereafter engaged (except for the
manufacture of Stand-alone Echo Cancellation Products). The exercise of such
rights shall be subject in all respects to Section 5.01.

          (b) Lucent's distribution right in Section 2.05(a) shall be limited to
     distributions to customers, suppliers, or other third parties as reasonably
     necessary with respect to any products or services of the businesses in
     which Lucent or any of its Subsidiaries is now or hereafter engaged (except
     for the manufacture of stand-alone Products of the Business) and as is
     consistent with current practices within the businesses of Lucent and its
     Subsidiaries.

     2.06 To Lucent's knowledge, a copy of all of the Assigned Software and
Assigned Technology already is in possession of the Business Employees or is
part of the Purchased Assets. However, Lucent shall, upon the Closing Date,
furnish to Purchaser any of the Assigned Technology and copies of the Assigned
Software (not already in Purchaser's possession as of the Closing Date) which
shall be deemed delivered on the date furnished unless and to the extent
Purchaser identifies in writing within sixty (60) days after such delivery
additional materials required to complete the delivery of such items pursuant to
this Agreement.

     ARTICLE 3 - LICENSE OF PATENTS

     3.01 Lucent and Lucent-GRL grant to Purchaser a personal, nonexclusive,
non-transferable (except as is otherwise set forth in Section 8.09), worldwide,
and fully paid-up license, under the Licensed Patents, to make, have made, use,
lease, sell, offer to sell and import the Products of the Business for use
within the Scope of the Business.

     3.02 In return for the additional consideration specified in Exhibit F
hereto, Lucent and Lucent-GRL grant to Purchaser a personal, nonexclusive,
non-transferable (except as is otherwise set forth in Section 8.09), worldwide,
and fully paid-up license, under the Licensed Patents, to make, have made, use,
lease, sell, offer to sell and import Stand-alone Echo Cancellation Products
and/or Licensed Products.

     3.03 The patent licenses granted in this Article 3 also include licenses,
where appropriate, (a) to make, have made, use and import machines, tools,
materials and other instrumentalities, insofar as such machines, tools,
materials and other instrumentalities are reasonably required for the
development, manufacture, testing or repair of the Products of the Business,
Licensed Products and Stand-alone Echo Cancellation Products which are or have
been made, used, leased, owned, sold or imported by the Purchaser; and (b) to
convey to any customer or authorized distributor of the Purchaser, with respect
to any such Product which is sold or leased by the Purchaser to such customer or
distributor, rights to use and resell such Product as sold or leased by the
Purchaser (whether or not as part of a larger combination); provided, however,
that no rights may be conveyed to customers or distributors with respect to any
invention which is directed to (i) a combination of such Product (as sold or
leased) with any other product, or (ii) a method or process which is other than
the inherent use of such Product itself (as sold or leased), or (iii) a method
or process involving the use of any such Product to manufacture (including
associated testing) any other product.

     3.04 The patent licenses granted herein to Purchaser are not to be
construed either (i) as consent by the grantor to any act which may be performed
by the grantee, except to the extent impacted by a patent licensed herein to the
grantee, or (ii) to include licenses to contributorily infringe or induce
infringement under U.S. law or a foreign equivalent thereof. Without limiting
the foregoing, the have made rights granted hereunder shall not be exercised in
a manner such that the exercise of the have made rights is a sham to sublicense
the Licensed Patents to a third party and not for BONA FIDE business purposes of
the Purchaser.

     3.05 All patent licenses granted herein shall continue for the entire
unexpired term of such patent or for as much of such term as Lucent has the
right to license such patent.

     3.06 Except as expressly provided in this Article 3, no rights are granted
under Lucent's inventions, patent applications or patents, whether by
implication, estoppel or otherwise.

forth in Article 6, the licenses granted to Purchaser in this Article 4, include
the right to grant non-exclusive sublicenses to third party manufacturers and

          by documentation in its possession, or is lawfully received free of
          restriction from another source having the right to so furnish such
          information; or

               (ii) after it has become generally available to the public by

          restrictions; or

               (v) which is requested pursuant to a judicial or governmental
          request, requirement or order under law, provided that such party
          provides the other party with sufficient prior notice and reasonable
          assistance in order to contest such request, requirement or order or
          seek protective measures; or

               (vi) which is furnished, in connection with a potential financing
          transaction, sale of all or a portion of the Business or similar
          transaction, to a prospective financing source or a prospective
          purchaser or their advisors or a government agency; or

          (c) The arbitrator shall be knowledgeable in the legal and technical

     damages. The arbitrator shall have no authority to award punitive or other
     damages, and each party irrevocably waives any claim thereto.

understanding between the parties as to the subject matter hereof and merges all
prior discussions between them. A party shall not be bound by any warranties,

with or subsequent to execution hereof by an authorized representative of the
party to be bound thereby.

     8.07 The parties hereto agree that the invalidity or unenforceability of
any of the provisions hereof shall not in anyway affect the validity or

provisions.

     8.08 Purchaser hereby assures Lucent that it will not without a license or
license exception authorized by the Bureau of Export Administration of the U.S.
Department of Commerce, Washington, D.C. 20230, United States of America, if

     code) obtained pursuant to this Agreement to a national of Country Groups
     D:1 or E:2 (15 C.F.R. Part 740, Supp. 1), Iran, Iraq, Sudan, or Syria; or

          (b) export to Country Groups D:1 or E:2, or to Iran, Iraq, Sudan, or
     Syria, the direct product (including processes and services) of the
     information or software; or

          (c) if the direct product of the information is a complete plant or
     any major component of a plant, export to Country Groups D:1 or E:2, or to

     8.09 Except as expressly authorized herein, neither this Intellectual
Property Agreement nor any rights under this Intellectual Property Agreement may
be assigned, sublicensed or otherwise transferred by either party, in whole or
in part, whether voluntarily or by operation of law (other than to (a) a
Subsidiary of such party provided such party guarantees the performance of such
Subsidiary hereunder or (b) a person that is a successor by sale of assets,
merger or otherwise to substantially all of the assets of such party who
executes a written agreement of assumption by which it agrees to be bound
hereby), without the prior written consent of the other party, which consent
will not be

<PAGE>

unreasonably withheld. The parties agree that a change in control of a party
shall not be deemed an "assignment" of this Intellectual Property Agreement.

     8.10 The grant of each license hereunder also includes the right of a party
to sublicense (within the scope of such party's own licenses and subject to the
provisions of this Agreement) any business which is divested by that party or
any of its Subsidiaries provided that the sublicense is granted within sixty
(60) days of divestiture and the divested business is itself a legal entity at
the time of divestiture or within sixty (60) days thereafter. Such sublicense
may continue for so long as the divested business remains a legal entity and
shall extend only to the licensed products of the kind sold or furnished by the
divested business prior to the divestiture and only for the rights of the
non-divesting Party licensed to the divesting party in this Agreement as of the
date of divestiture. Furthermore, any sublicense shall not extend to the
products sold or services furnished by a third party which acquires the divested
business, even if they are of the same kind or similar to those of the divested
business and even if made, sold or provided by the divested business. This
Section shall apply regardless of whether the business is divested by a
distribution to existing shareholders, a sale of assets or as a sale of a legal
entity (e.g., sale of a Subsidiary).

     8.11 This Intellectual Property Agreement may be executed in any number of
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

     8.12 All article headings and the table of contents are for convenience
purposes only and shall in no way affect, or be used in, the interpretation of
this Agreement.

     ARTICLE 9 - NOTICES
