         4.3 RETENTION OF RIGHTS BY LICENSEE. Except as otherwise expressly
provided in this Agreement, Licensee shall retain all rights in and to the
Corporate Identification Mark, alone and as used in the Transition Logos,
including without limitation:

                  (a) All rights of ownership in and to the Corporate
Identification Mark;

                 (b) The right to use (including the right of Licensee's
Affiliates to use) the Corporate Identification Mark, either alone or in
combination with other marks, in connection with the marketing, offer or
provision of any product or service, including any product or service which

                                    ARTICLE V
                               LICENSED TERRITORY

         5.1 The Licensed Territory for the licenses granted in Article II of
this Agreement shall include the world, but such licenses do not authorize the
marketing, offering or sale of Avaya Products under the Licensed Marks or the
Transition Logos in any country in which no Avaya Products were being marketed,
offered or sold as of the Effective Date, except:

                 (a) If a contract with an Existing Authorized Dealer grants
rights to commence marketing an Avaya Product in a new country, then that new
country shall be included in the Licensed Territory with respect to that
particular Avaya Product; and

                 (b) Licensee may use the Licensed Marks or the Transition Logos
subject to the terms and conditions of this Agreement, in countries where, as of
the date hereof, it had developed bona-fide, good faith plans to commence
marketing an Avaya Product, which countries are identified in Schedule K hereto.
Schedule K shall in all events be completed to the mutual satisfaction of
Licensor and Licensee no later than December 31, 2000.


                                   ARTICLE VI
                                 QUALITY CONTROL

         6.1 GENERAL. Licensee acknowledges that the Avaya Products covered by
this

                                       7
<PAGE>   12
Agreement must continue to be of sufficiently high quality as to provide maximum
enhancement to and protection of the Licensed Marks and the Transition Logos and
the goodwill they symbolize. Licensee further acknowledges that the maintenance
of high quality Avaya Products is of the essence of this Agreement and that it
will utilize only marketing materials which do not disparage Licensor or place
in disrepute, its businesses or its business reputation, or adversely affect or
detract from Licensor's goodwill.

         6.2 CONTROL AND TRADEMARK USE SPECIFICATIONS. (a) Licensee shall use
the Licensed Marks and the Transition Logos only in connection with the
manufacture, marketing, distribution, promotion, and sale of Avaya Products that
meet the Control and Trademark Use Specifications. The Control and Trademark Use
Specifications shall consist of Technical Performance, Customer Service, and
Customer Satisfaction Specifications attached or referenced in Schedule B hereto
and the Trademark Use Specifications referenced in Schedule C hereto. The
Control and Trademark Use Specifications shall be treated as proprietary
information and shall be subject to the confidentiality provisions of Article I
of the Contribution and Distribution Agreement.

                  (b) Licensee shall not offer any Avaya Product under the
Licensed Marks or the Transition Logos unless it meets each of the relevant
Control and Trademark Use Specifications. Licensee shall not provide to any
third party any product which does not meet the Control and Trademark Use
Specifications without first obliterating the Licensed Marks or the Transition
Logos.

          6.3 CUSTOMER CARE PROVISIONS. If Licensor receives a customer
complaint regarding an Avaya Product branded under this Agreement, it will
promptly notify Licensee and Licensee will use reasonable commercial efforts to
resolve any such complaints or any other complaints received for products
branded under this Agreement as it would for complaints received for products
branded under the Avaya mark.

          6.4 QUALITY CONTROL REVIEWS; RIGHT OF INSPECTION. Licensor shall have
the right to designate from time to time, one or more Quality Control
Representatives, who shall have the right from time to time, but no more than
once per calendar quarter, upon ten (10) days' notice to Licensee, to conduct
during regular business hours an inspection, test, survey and review of
Licensee's facilities and the facilities of Licensee's Authorized Dealers, if
any, and otherwise to determine compliance with the applicable Control and
Trademark Use Specifications. At Licensor's request, Licensee agrees to furnish
or make available for inspection to the Quality Control Representatives: (i)
samples of any Avaya Product that is marketed or provided under the Licensed
Marks or the Transition Logos for inspections, surveys, tests and reviews to
assure conformance with the applicable Control and Trademark Use Specifications;
(ii) performance data in its control relating to the conformance of Avaya
Products with the applicable Control and Trademark Use Specifications, and (iii)
samples of marketing materials, product packaging labels, instruction and
warranty materials that use the Licensed Marks or the Transition Logos. Any such
data provided to Licensor shall be treated as proprietary information subject to
the confidentiality provisions of Article I of the Contribution and Distribution
Agreement. Licensor may independently, and at its own expense, conduct
continuous customer satisfaction surveys to determine if Licensee and its
Authorized Dealers are meeting the Control and Trademark Use

                                       8
<PAGE>   13
Specifications. Licensee shall cooperate with Licensor fully in the distribution
of such surveys. Licensor shall, at the request of Licensee, provide Licensee
with copies of customer surveys used by Licensor to determine if Licensee is
meeting the Control and Trademark Use Specifications. If Licensee learns that it
or any of its Authorized Dealers is not complying with any Control and Trademark
Use Specifications, it shall notify Licensor and the provisions of Article VII
(and of Section 3.3(a) in the case of Authorized Dealers) shall apply to such
noncompliance.

         6.4 SPONSORSHIP. Beginning three months from the Effective Date,
Licensee shall not use the Licensed Marks to sponsor, endorse, or claim
affiliation with any event, meeting, charitable endeavor or any other
undertaking without obtaining the express written permission of Licensor. Any
breach of this provision shall be deemed a Significant Breach by Licensee.

         6.5 DISCONTINUATION. If, during the term of this Agreement, Licensee
discontinues the retail provision of an Avaya Product that has been sold under
the Licensed Marks or the Transition Logos, Licensee shall comply with an "End
of Life" plan that satisfies the requirements of Schedule H hereto. Licensee
shall consult with Licensor prior to finalizing any End of Life Plan required by
this Section and submit an advance copy of such plan to Licensor.

         6.6 REFURBISHED PRODUCT. Licensee shall not sell, convey, assign its
interest in or otherwise transfer to any refurbisher or reconditioner any
Product bearing the Licensed Marks without first obliterating the Licensed Marks
and any other reference to Licensor from all products, packaging, instruction
and warranty materials provided to such refurbisher or reconditioner.

         6.7 COSTS. All reasonable costs associated with monitoring compliance
with and enforcing these quality control provisions, and with administering this
Agreement, shall be borne by Licensee. Licensor shall provide to Licensee a
quarterly invoice itemizing with reasonable specificity the costs incurred
during the prior quarter, which shall be due and payable by Licensee within
thirty (30) days of receipt.


                                   ARTICLE VII
    REMEDIES FOR NONCOMPLIANCE WITH CONTROL AND TRADEMARK USE SPECIFICATIONS

         7.1 CURE PERIOD. If Licensor becomes aware that Licensee or any
Authorized Dealer is not complying with any provision of the Control and
Trademark Use Specifications, Licensor shall notify Licensee in writing, setting
forth in reasonable detail, a written description of the noncompliance and any
suggestions for curing such noncompliance. Licensee shall then have forty five
(45) days after receipt of such notice (the "Cure Period") to correct or submit
to Licensor a written plan, reasonably acceptable to Licensor, to correct such
noncompliance.

         7.2 FAILURE TO CURE. If the noncompliance with the Control and
Trademark Use Specifications identified pursuant to Section 7.1 continues beyond
the Cure Period, Licensee shall: (i) cease offering such Avaya Products under
the Licensed Marks or the Transition Logos until it can comply with the Control
and Trademark Use Specifications; or (ii) be deemed to be

                                       9
<PAGE>   14
in Significant Breach of this Agreement.


                                  ARTICLE VIII
          PROTECTION OF LICENSED SERVICE MARKS AND THE TRANSITION LOGOS

          8.1 OWNERSHIP AND RIGHTS. (a) Licensee admits the validity of, and
agrees not to challenge the ownership or validity of, the Licensed Marks alone
and in the Transition Logos. Licensee shall not disparage, dilute or adversely
affect the validity of the Licensed Marks or the Transition Logos. Licensee
agrees that any and all goodwill and other rights that Licensee may acquire by
the use of the Licensed Marks alone and in the Transition Logos shall inure to
the sole benefit of Licensor. Licensee will not grant or attempt to grant a
security interest in the Licensed Marks or Transition Logos, or this Agreement,
or to record any such security interest in the United States Patent and
Trademark Office or elsewhere, against any trademark application or registration
belonging to Licensor. To the extent necessary, Licensee agrees to execute all
documents reasonably requested by Licensor to effect further registration of,
maintenance and renewal of the Licensed Marks and recordal of the license
relationship between Licensor and Licensee and recordal of Licensee as a
Registered User. For purposes of this Agreement, Licensee shall be considered a
"related company" under the U.S. Trademark Act, 15 U.S.C. Section 1051 et seq.

                  (b) LICENSOR admits the validity of, and agrees not to
challenge the ownership or validity of, the Corporate Identification Marks alone
and in the Transition Logos. Licensor shall not disparage, dilute or adversely
affect the validity of the Corporate Identification Marks or the Transition
Logos. Licensor agrees that any and all goodwill and other rights that Licensor
may acquire by the use of the Corporate Identification Marks alone and in the
Transition Logos shall inure to the sole benefit of Licensee. Licensor will not
grant or attempt to grant a security interest in the Corporate Identification
Marks or Transition Logos, or this Agreement, or to record any such security
interest in the United States Patent and Trademark Office or elsewhere, against
any trademark application or registration belonging to Licensee. To the extent
necessary, Licensor agrees to execute all documents reasonably requested by
Licensee to effect further registration of, maintenance and renewal of the
Corporate Identification Marks and recordal of the license relationship between
Licensee and Licensor. For purposes of this Agreement, Licensor shall be
considered a "related company" under the U.S. Trademark Act, 15 U.S.C. Section
1051 et seq.

         8.2 SIMILAR MARKS. (a) Licensee further agrees not to register in any
country any Mark resembling or confusingly similar to the Licensed Marks and not
to use the Licensed Marks or any part thereof as part of its corporate name
(except as otherwise expressly permitted hereunder), nor use any Mark
confusingly similar, deceptive or misleading with respect to the Licensed Marks
or which dilute the Licensed Marks. If any application for registration is, or
has been, filed in any country by Licensee which relates to any Mark which in
the sole opinion of Licensor, is confusingly similar, deceptive or misleading
with respect to the Licensed Marks, or which dilutes the Licensed Marks,
Licensee shall, at Licensor's sole discretion, immediately abandon any such
application or registration or assign it to Licensor. If Licensee uses any Mark
which in the sole opinion of Licensor, is confusingly similar, deceptive or
misleading with


                                       10

<PAGE>   15
respect to the Licensed Marks, or which dilutes the Licensed Marks, or if
Licensee uses the Licensed Marks in connection with any product, or in
connection with any service not specifically authorized hereunder, Licensee
shall, immediately upon receiving a written request from Licensor, permanently
cease such use.

                  (b) The parties agree that neither will apply to register the
Transition Logos, and that Licensee will have the sole and exclusive right to
use and register the Corporate Identification Mark.

          8.3 INFRINGEMENT. In the event that Licensee learns of any
infringement or threatened infringement of the Licensed Marks, either alone or
as contained in Compound Marks or the Transition Logos, or any unfair
competition, passing-off or dilution with respect to the same, or any third
party alleges or claims that said Licensed Marks are liable to cause deception
or confusion to the public, or is liable to dilute or infringe any right of such
third party, Licensee shall immediately notify Licensor or its authorized
representative giving particulars thereof and Licensee shall provide necessary
information and assistance to Licensor or its authorized representatives in the
event that Licensor decides that proceedings should be commenced or defended.
Licensee's reasonable expenses in providing such assistance shall be borne by
Licensor. Licensor shall have exclusive control of any litigation, opposition,
cancellation or related legal proceedings. The decision whether to bring,
defend, maintain or settle any such proceedings shall be at the exclusive option
and expense of Licensor, and all recoveries shall belong exclusively to
Licensor. Licensee will not initiate any such litigation, opposition,
cancellation or related legal proceedings in its own name. Nothing in this
Agreement shall require or be deemed to require Licensor to enforce the Licensed
Marks or the Transition Logos against others. Nothing herein will limit
Licensee's ability to initiate any litigation, opposition, cancellation or
related legal proceedings in its own name with regard to those elements of the
Compound Marks and Transition Logos owned exclusively by Licensee.

         8.4 COMPLIANCE WITH LAWS. In the performance of this Agreement,
Licensee shall comply with all applicable laws and regulations, including those
laws and regulations particularly pertaining to the proper use and designation
of Marks. Should Licensee be or become aware of any applicable laws or
regulations which are inconsistent with the provisions of this Agreement,
Licensee shall promptly notify Licensor of such inconsistency. In such event,
Licensor may, at its option, either waive the performance of such inconsistent
provisions, or negotiate with Licensee to make changes in such provisions to
comply with applicable laws and regulations.

         9.1 BREACH BY LICENSEE. Licensor may terminate this Agreement at any
time in the event of a Significant Breach by Licensee. A "Significant Breach by
Licensee" shall mean any event expressly specified in this Agreement to be a
"Significant Breach," and any of the following (after exhaustion of any Cure
Periods set forth in Article VII hereof to the extent such Cure Periods are
applicable):

                  (a) Licensee's or any Authorized Dealer's use of the Licensed
Marks or the Transition Logos contrary to the provisions of this Agreement,
provided, however, that such use contrary to this Agreement by a particular
Authorized Dealer shall be grounds for termination only as to that particular
Authorized Dealer; further provided that a pattern of violations without cure of
any provision of this Agreement, including Section 2.5, by a number of
Licensee's Authorized Dealers shall be grounds for termination as to those
Authorized Dealers, or all Authorized Dealers, at the sole discretion of
Licensor.

                  (b) Licensee's or any Authorized Dealer's use of a Licensed
Mark or the Transition Logos in connection with any marketing materials, or the
offering, marketing or provision of any Avaya Product, which fail to meet the
standards set forth in the Control and Trademark Use Specifications; provided,
however, that (i) the failure of a particular product to comply with the Control
and Trademark Use Specifications shall be grounds for termination only as to
that product; further provided that continued use of the Licensed Marks or the
Transition Logos by Licensee in connection with such product shall be grounds
for termination of the Agreement as to all Avaya Products, and (ii) except as
otherwise provided in Paragraph (a) above, the failure of an Authorized Dealer
to satisfy the standards set forth in the Control and Trademark Use
Specifications shall be grounds for termination only as to that particular
Authorized Dealer;

                  (c) Licensee's refusing or neglecting a request by Licensor
for access to Licensee's facilities, products or marketing materials;

                  (d) Unless otherwise permitted herein, Licensee's licensing,
assigning, transferring, disposing of or relinquishing (or purporting to
license, assign, transfer, dispose of or relinquish) any of the rights granted
in this Agreement to others;

                  (e) Licensee's failure to take appropriate steps to restrain
any Authorized Dealer from violating the terms and conditions of this Agreement;

                  (f) Licensee's receipt of any license, right or permission to
market, or the marketing by Licensee of, any product or service under any name,
mark, indication of origin or trade dress or the logo of any Person that
competes with Licensor in the provision of products or services; provided,
however, that Licensee may contract manufacture products for any Person
including any Person that competes with Licensor in the provision of Lucent
Products which do not bear the Licensed Marks or the Transition Logos, so long
as such Person makes no reference in any promotional, marketing information or
other material to Licensor or Licensee's relationship to Licensor;

                  (g) The bankruptcy or insolvency of Licensee; provided,
however, that the bankruptcy or insolvency of an Affiliate or Subsidiary of
Licensee shall be grounds for termination of this Agreement only as to that
Affiliate or Subsidiary;

                  (h) Licensee's failure to obtain Licensor's permission to
sponsor any undertaking as provided in Section 6.4 of this Agreement;

                 (i) Licensee's failure to develop, provide to Licensor an
advance copy of or comply with an End of Life Plan, as required by Section 6.5
of this Agreement.

         9.2 TERMINATION OBLIGATIONS. In the event Licensor terminates this
Agreement pursuant to this Article:

          (a) Licensee and all Authorized Dealers (or such of the foregoing as
to which this Agreement is terminated) shall immediately cease all use of the
Licensed Marks or the Transition Logos upon notice of termination; provided,
however, that nothing herein shall be construed to prohibit Licensee from making
truthful statements of fact regarding its past affiliation with Licensor, so
long as such statements are not likely to cause confusion, mistake or deception.

          (b) Licensee and all Authorized Dealers (or such of the foregoing as
to which this Agreement is terminated) shall have no further rights under this
Agreement.


                                    ARTICLE X

from or in connection with Licensee's or any Authorized Dealer's, manufacture,
marketing, sale, or use of Avaya Products bearing the Licensed Marks or the
Transition Logos after the date of this Agreement, and shall indemnify Licensor
and each Lucent Indemnitee for all damages, losses, costs and expenses

        10.2 NOTICE. Licensee shall notify Licensor, in writing, in the event
that any third party claims, by suit, proceeding, action or otherwise, that
Licensee's use of the Licensed Marks, alone or as used in the Transition Logos
in connection with Avaya Products as provided in this Agreement constitutes or
amounts to a trademark or service mark infringement, unfair competition or
dilution, and, at Licensor's option, Licensee may be directed to surrender
control of the defense of such claims to Licensor.


                                   ARTICLE XI

                        MEDIATION AND DISPUTE RESOLUTION

         13.1 DISPUTES. The provisions set forth in this Article shall apply to
all disputes, controversies or claims (whether arising in contract, tort or
otherwise) that may arise out of or relate to, or arise under or in connection
with this Agreement.

         13.2 ESCALATION; MEDIATION.

                  (a) It is the intent of the parties to use their respective
reasonable best efforts to resolve expeditiously and on a mutually acceptable
negotiated basis any dispute, controversy or claim between them with respect to
the matters covered hereby that may arise from time to time. In furtherance of
the foregoing, any party involved in a dispute, controversy or claim may deliver
a notice (an "Escalation Notice") demanding an in-person meeting involving
representatives of the parties at a senior level of management of the parties
(or if the parties agree, of the appropriate strategic business unit or division
within such entity). A copy of any such Escalation Notice shall be given to the
General Counsel, or like officer or official, of each party involved in the
dispute, controversy or claim (which copy shall state that it is an Escalation
Notice pursuant to this Agreement). Any agenda, location or procedures for such
discussions or negotiations between the parties may be established by the
parties from time to time; provided, however, that the parties shall use their
reasonable best efforts to meet within thirty (30) days of the Escalation
Notice.

                  (b) If the parties are not able to resolve the dispute,
controversy or claim through the escalation process referred to above, then the
matter shall be referred to mediation. The parties shall retain a mediator to
aid in their discussions and negotiations by informally providing advice to the
parties. Any opinion expressed by the mediator shall be strictly advisory and
shall not be binding on the parties, nor shall any opinion expressed by the
mediator be admissible in any other proceeding. The mediator may be chosen from
a list of mediators previously selected by the parties or by other agreement of
the parties. Costs of the mediation shall be borne equally by the parties
involved in the matter, except that each party shall be responsible for its own
expenses. Mediation shall be a prerequisite to the commencement of any action by
either party.

         13.3  COURT ACTIONS.

                  (a) In the event that any party, after complying with the
provisions set forth in Section 13.2 above, desires to commence an action, such
party may submit the dispute, controversy or claim (or series of related
disputes, controversies or claims) giving rise thereto to a court of competent
jurisdiction.

                  (b) Unless otherwise agreed in writing, the parties will
continue to provide service and honor all other commitments under this Agreement
during the course of dispute resolution pursuant to the provisions of this
Article with respect to all matters not subject to such dispute, controversy or

between the parties other than those set forth or referred to herein.

                  (c) Each party represents as follows:

                      (i)    each has the requisite corporate or other power and
                             authority and has taken all corporate or other
                             action necessary in order to execute, deliver and
                             perform this Agreement and to consummate the
                             transactions contemplated hereby; and

                      (ii)   this Agreement has been duly executed and delivered
                             by it and constitutes a valid and binding agreement
                             of it enforceable in accordance with the terms
                             thereof.

         14.2 GOVERNING LAW. This Agreement shall be governed by and construed
and interpreted in accordance with the laws of the State of New York applicable
to contracts to be performed solely within the State of New York, as to all
matters, including matters of validity, construction, effect, enforceability,

neither party may assign this Agreement, in whole or in part, or its respective
rights or obligations without the prior written consent of the other party.

         14.4 RELATIONSHIP OF THE PARTIES; THIRD PARTY BENEFICIARIES.

                  (a) Nothing in this Agreement shall be deemed or construed by
the parties or any third party as creating the relationship of principal and
agent, partnership or joint venture between the parties, it being understood and
agreed that no provision contained herein, and no act of the parties, shall be
deemed to create any relationship between the parties other than the
relationship of independent contractor.

                  (b) The provisions of this Agreement are solely for the
benefit of the parties and are not intended to confer upon any Person except the
parties any rights or remedies hereunder, and there are no third party
beneficiaries of this Agreement, and this Agreement shall not provide any third
Person with any remedy, claim, liability, reimbursement, claim of action or
other right in addition to those existing without reference to this Agreement.

         14.5 SEVERABILITY. If any provision of this Agreement or the
application thereof to any Person or circumstance is determined by a court of
competent jurisdiction to be invalid, void or unenforceable, the remaining
provisions hereof, or the application of such provision to Persons or
circumstances or in jurisdictions other than those as to which it has been held
invalid or unenforceable, shall remain in full force and effect and shall in no
way be affected, impaired or invalidated thereby, so long as the economic or
legal substance of the transactions contemplated hereby or thereby, as the case
may be, is not affected in any manner adverse to any party. Upon such
determination, the parties shall negotiate in good faith in an effort to agree
upon such a suitable and equitable provision to effect the original intent of
the parties.

         14.6 FORCE MAJEURE. No party shall be deemed in default of this
Agreement to the extent that any delay or failure in the performance of its
obligations under this Agreement results from any cause beyond its reasonable
control and without its fault or negligence, such as acts of God, acts of civil
or military authority, embargoes, epidemics, war, riots, insurrections, fires,
explosions, earthquakes, floods, unusually severe weather conditions, labor
problems or unavailability of parts or raw materials, or, in the case of
computer systems, any failure in electrical or air conditioning equipment. In
the event of any such excused delay, the time for performance shall be extended
for a period equal to the time lost by reason of the delay.

         14.7 PUBLICITY. The parties agree to consult and cooperate with each
other prior to issuing any press releases, articles, advertising, or publicity
materials relating to Products under this Agreement or this Agreement which use
the trademarks, logos, trade name, service mark or other company identification
of the other party, with the exception of the Transition Logos or factual
references and except as may be required by governmental regulation or court
order, or any of its Affiliates or any of its personnel.

         14.9 WAIVERS OF DEFAULT. Waiver by any party of any default by the
other party of any provision of this Agreement shall not be deemed a waiver by
the waiving party of any subsequent or other default, nor shall it prejudice the
rights of the other party.

         14.10 INJUNCTIVE RELIEF. In the event of any actual or threatened
default in, or breach of, any of the terms, conditions and provisions of this
Agreement, the party or parties who are or are to be thereby aggrieved shall
have the right to injunctive or other equitable relief of its rights under this
Agreement, in addition to any and all other rights and remedies at law or in
equity, and all such rights and remedies shall be cumulative. The parties agree
that the remedies at law for any breach or threatened breach, including monetary
damages, are inadequate compensation for any loss and that any defense in any
action for injunctive relief that a remedy at law would be adequate is waived.
Any requirements for the securing or posting of any bond with such remedy are
waived.

         14.11 AMENDMENTS. No provision of this Agreement shall be deemed
waived, amended, supplemented or modified by any party, unless such waiver,

amendment, supplement or modification.
