      (c) The procurement rights granted hereunder to each one of the parties
under this Section 2.5 shall not be exercised by one party in a manner such that
the exercise of such one party's procurement rights is a sham to effect the
licensing of another party's Licensed Technology or any portion thereof, to a
third party and not for bona fide business purposes of such one party.

      (d) Each party agrees that prior to the disclosure of any portion of
Licensed Technology under this Section 2.5, all extraneous proprietary
information of the other parties shall be expunged.


                                   ARTICLE III
                                 PATENT LICENSES

      3.1 GRANTS TO AGERE. (a) GRL grants to Agere and Agere Guardian, under
GRL's Patents, worldwide, personal, nonexclusive, and non-transferable licenses
to make, have made (subject to 3.1(b)), use, lease, sell, offer for sale and
import any and all products and services of the businesses in which Agere or
Agere Guardian, or any of their Related Companies is now or hereafter engaged.

      (b) The right of Agere and Agere Guardian to have product made pursuant to
this Agreement is not limited to products custom designed by or for Agere and
Agere Guardian. Such "have made" rights shall include the right to have "off the
shelf" products made for or procured by Agere and Agere Guardian. The "have
made" rights shall not be exercised by Agere and Agere Guardian in a manner such
that the exercise of those rights is a sham to sublicense GRL's Patents to a
third party.

      (c) GRL hereby further grants to Agere a sublicense under any and all
patent license rights, with respect to which GRL has received from any third
party pursuant to any license agreement a right to sublicense (but only to the
extent that GRL has a right to grant such a sublicense without payment of
royalties, loss of rights or imposition of a penalty), to make, have made, use,
lease, offer to sell, sell, and import any and all products and services. To the
extent that GRL's right to grant sublicenses to divested entities under any
license agreement is limited to a grant made within a specified time period with
respect to a divestiture, then the sublicenses granted to Agere under this
Section 3.1(c) shall be deemed to have occurred at the earliest date permitted
in such license agreement.

      3.2 GRANTS TO LUCENT. (a) Agere Guardian grants to Lucent and GRL, under
Agere Guardian's Patents, worldwide, personal, nonexclusive, and
non-transferable licenses to make, have made (subject to 3.2(b)), use, lease,
sell, offer for sale and import any and all products and services of the
businesses in which Lucent and GRL or any of their Related Companies is now or
hereafter engaged.

      (b) The right of Lucent and GRL to have product made pursuant to this
Agreement is not limited to products custom designed by or for Lucent and GRL.
Such


                                       8
<PAGE>   16
"have made" rights shall include the right to have "off the shelf" products made
for or procured by Lucent and GRL. The "have made" rights shall not be exercised
by Lucent and GRL in a manner such that the exercise of those rights is a sham
to sublicense Agere Guardian's Patents to a third party.

      3.3 DURATION AND EXTENT OF LICENSES. Subject to Article VIII, all licenses
granted herein as to any party's patents shall continue for the entire unexpired
term of such patents.

      3.4 SCOPE OF LICENSES. (a) The licenses granted herein include licenses to
convey to any customer of the grantee, with respect to any licensed product
which is sold or leased by such grantee to such customer, rights to use and
resell such licensed product as sold or leased by such grantee (whether or not
as part of a larger combination); provided, however, that no rights may be
conveyed to customers with respect to any invention which is directed to (1) a
combination of such licensed products(s) (as sold or leased) with any other
product that is not a licensed product, (2) a method or process other than a
method or process the inventive steps of which are implemented primarily by the
licensed product(s) in the operation of such licensed products(s) or (3) a
method or process involving the use of a licensed product to manufacture any
other product and to test any such manufactured product.

      (b) For a period of three (3) years after the Effective Date, the scope of
the licenses granted to Agere and Agere Guardian as defined in Section 3.4(a)
shall further include, in addition to the rights granted hereinabove with
respect to a licensed product sold to a customer of Agere, the rights to convey
to that customer, a license under only (i) U.S. Patent 4,582,956 issued to
Doughty, and (ii) those of GRL's Patents with respect to which at least one
inventor named on the patent was an employee of the Microelectronics or
Optoelectronics business unit of Lucent at the time the invention was made, with
respect to an invention which is directed to a combination of such licensed
product(s) (as sold or leased) with any other product that is not a licensed
product, provided that the licensed product(s) embodies a substantial and
significant portion of the invention, and further provided that the customer is
not already licensed by Lucent or GRL with respect to such invention. After
three (3) years from the Effective Date, Agere and Agere Guardian shall have no
further right to convey to customers rights and licenses permitted to be
conveyed pursuant to this Section 3.4(b).

      (c) Licenses granted herein are not to be construed: (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, (ii) except as otherwise
specifically provided under Section 3.4(a) or 3.4(b), a waiver of a party's (or
any of its Related Companies') rights against any third party with respect to
any infringement or (iii) to include licenses to contributorily infringe or
induce infringement under U.S. law or a foreign equivalent thereof (collectively
"Indirect Infringement"). Notwithstanding the foregoing sentence, each party
agrees for itself and its Related Companies licensed hereunder that they will
not bring suit or otherwise exercise any of their remedies under their
respective licensed patents (i.e., GRL's Patents and Agere Guardian's Patents,
as the case may be) against


                                       9
<PAGE>   17
the other party or its Related Companies licensed hereunder, for Indirect
Infringement. However, the parties agree that all remedies available under such
patents against a third party direct infringer are not waived, and will still be
in full force and effect, and that such third party direct infringers will not
be relieved of any liability for such direct infringement. In the event that any
court of competent jurisdiction determines that the agreement by the parties
hereto not to bring suit for indirect infringement eliminates the liability of,
or reduces the damages against, a third party direct infringer, then the
agreement of the parties not to bring suit against each other for Indirect
Infringement shall be automatically terminated. Concurrent with such
termination, this agreement shall be deemed to have been amended to include the
following language in lieu of the sentence beginning "Notwithstanding the
foregoing sentence, each party ...": "Notwithstanding the foregoing sentence,
each party agrees for itself and its Related Companies licensed hereunder that
they will not bring suit or otherwise exercise any of their remedies under their
respective licensed patents (i.e., GRL's Patents and Agere Guardian's Patents,
as the case may be) against the other party or its Related Companies licensed
hereunder, for Indirect Infringement until fully exhausting all remedies
available under such patents against the third party direct infringer(s) for the
direct infringement which gives rise to such Indirect Infringements."

      (d) The grant of each license hereunder to each party includes the right
to grant sublicenses within the scope of such license to a party's Related
Companies for so long as they remain Related Companies of such party. Any such
sublicense may be made effective retroactively, but not prior to the Effective
Date, nor prior to the sublicensee's becoming a Related Company of such party.

      3.5 FILINGS OF PATENT APPLICATIONS. Each party agrees to file patent
applications within the period prior to February 1, 2003 in a timely manner as
determined by generally accepted good patent filing practices and as though this
Agreement were not in existence between the parties. The dispute resolution
provisions of Article IX of the Separation and Distribution Agreement shall
apply to any allegation by one party that another party hereto has purposely
delayed its patent filings primarily to avoid providing the licenses and rights
granted hereunder.

      3.6 JOINT INVENTIONS. (a) There are countries (not including the
United States) which require the express consent of all inventors or their
assignees to the grant of licenses or rights under patents issued in such
countries for joint inventions.

      (b) Each party shall give such consent, or shall use its reasonable best
efforts to obtain such consent from its Related Companies, its employees or
employees of any of its Related Companies, as required to make full and
effective any such licenses and rights respecting any joint invention granted to
a grantee hereunder by such party and by another licensor of such grantee.

      (c) Each party shall take steps which are reasonable under the
circumstances to obtain from third parties whatever other consents are necessary
to make full and effective such licenses and rights respecting any joint
invention purported to be granted by it


                                       10
<PAGE>   18
hereunder. If, in spite of such reasonable steps, such party is unable to obtain
the requisite consents from such third parties, the resulting inability of such
party to make full and effective its purported grant of such licenses and rights
shall not be considered to be a breach of this Agreement.

      3.7 OUTSIDE THE UNITED STATES. (a) There are countries in which the owner
of an invention is entitled to damages, compensation or other monetary award for
another's unlicensed manufacture, sale, lease, use or importation involving such
invention prior to the date of issuance of a patent for such invention but on or
after a certain earlier date, hereinafter referred to as the invention's
"protection commencement date" (e.g., the date of publication of allowed claims
or the date of publication or "laying open" of the filed patent application). In
some instances, other conditions precedent must also be fulfilled (e.g.,
knowledge or actual notification of the filed patent application). The parties
agree that (i) an invention which has a protection commencement date in any such
country may be used in such country pursuant to the terms of this Agreement on
and after any such date, and (ii) all such conditions precedent are deemed
satisfied by this Agreement.

      (b) There may be countries in which a party hereto may have, as a
consequence of this Agreement, rights against third party infringers of another
party's patents licensed hereunder. Each party hereto hereby waives any such
right it may have by reason of such third party's infringement or alleged
infringement of another party's patents.

      (c) Each party hereto hereby agrees to register or cause to be registered,
to the extent that such party reasonably determines that registration or
recordation is necessary under applicable law, and without expense to the other
party or any of its Related Companies, any agreements wherein sublicenses are
granted by it under the other party's patents licensed hereunder. Each party
hereto hereby waives any and all claims or defenses, arising by virtue of the
absence of such registration, that might otherwise limit or affect its
obligations to the other party.

      3.8 DEFENSIVE PROTECTION ARRANGEMENT. If, during the period ending five
(5) years after the Effective Date, any third party sues Agere for patent
infringement with respect to any Agere product(s), then Agere shall have, during
the pendency of the action, (i) the right to assert against such third party,
counterclaims of infringement of not more than six (6) of the Designated
Defensive Patents listed in Exhibit I selected by Agere, and (ii) the exclusive
right to license said third party under such six (6) Designated Defensive
Patents solely for the purposes of settling such litigation. Agere shall control
the litigation (both the defense of the initial claim by the third party, and
the assertion of a counterclaim under the Designated Defensive Patents), and
Agere shall bear all costs and expenses associated therewith. Any royalty
revenues and judgment obtained from or against a third party on account of such
selected Designated Defensive Patents shall be first applied to Agere's costs
and expenses of the litigation, and any amount received in excess of such costs
and expenses shall be equally divided between Agere and Lucent.

      Before exercising such right, Agere shall give notice to Lucent, and shall
afford Lucent, at Lucent's option, the opportunity to transfer to Agere for the
duration of the


                                       11
<PAGE>   19
litigation, either a partial interest in the patent(s) sufficient to enable
Agere to bring suit, or a full interest in the patent(s). Agere agrees to accept
such transfer, and to return such interest to Lucent at the conclusion of the
litigation.

      If any rights are exercised pursuant to this Section, Agere agrees to
reasonably consult with Lucent during such litigation, to comply with reasonable
requests made by Lucent regarding the status of the litigation, and to indemnify
and hold Lucent harmless from and against any claim, loss or damage (including
reasonable attorneys fees) arising out of or resulting from Agere's exercise of
the rights granted by Lucent to Agere under this provision, excluding, however,
claims against Lucent for patent infringement.

      3.9 LICENSING PRIOR TO DISTRIBUTION DATE. Between the Effective Date and
Distribution Date, unless expressly permitted in this Agreement or in any
Ancillary Agreement as defined in the Separation and Distribution Agreement, (i)
Agere and its Related Companies shall not, without the express written
permission of Lucent, enter into any agreement to license any patent or other
intellectual property solely owned by Lucent or its Related Companies to a third
party, and (ii) Lucent and its Related Companies shall not, without the express
written permission of Agere, enter into any agreement to license any patent or
other intellectual property owned solely by Agere or its Related Companies to a
third party.

(c) and (d), respectively) with respect to infringement of Necessary Patents (as
defined in Section (e)) that may occur by virtue of the manufacture, use or sale
of Impacted Products, as defined in Section (b).

      (b) Impacted Product means any product made by a Person with whom Lucent
or Agere, as the case may be, has a Supply Relationship or a Joint Development
Relationship, that makes substantial and significant use of technology (i) that
exists as of the Effective Date (ii) is furnished by Lucent or Agere to the

<PAGE>   23
      (e)  Necessary Patents shall include, in the case of Lucent (Agere)
any claim of any patent

             (i)    which is based upon an application first filed as of the
                    Effective Date;

             (ii)   which Lucent (Agere) or any of their respective Related
                    Companies, owns or has the right to license as of the

make, use and sell Impacted Products on commercially reasonable terms and
conditions. For the purposes of this section 3.12(g), commercially reasonable
terms and conditions shall be deemed to include a royalty payment to the
licensing Party not to exceed the lesser of (i) One Half of One Percent (0.5%)
of the fair market value of the Impacted Products for each Necessary Patent, or
(ii) Two Percent (2%) of the fair market value of the Impacted Products.

                                    ARTICLE V
          RIGHTS RELATED TO PRODUCTS SOURCED BY LUCENT FROM AGERE

      5.1   DEFINITIONS.  For the purposes of this Article V:

      5.1.1 " Joint Technical Information" shall mean those specifications,
drawings, schematics, software, test programs, mask works, parts lists,
engineering notes, process instructions and any other information in Lucent's
possession and limited to Restricted Joint Corporate Technology specifically
listed in Exhibit F and Agere Restricted Joint Corporate Technology listed in
Exhibit G. Joint Technical Information shall not include any information that is
solely owned by Agere.

      5.1.2 "Agere's Required Patents" shall mean any claim of any patent owned
by Agere or Agere's wholly-owned Subsidiaries, or for which Agere or Agere's
wholly-owned Subsidiaries has an exclusive license pursuant to Section 3.10,
which reads on and which is necessarily infringed by the manufacture or sale of
a Sourced Product (as defined below in Section 5.2) that uses or is based upon
Joint Technical Information.

      5.1.3 "Supply Agreement" shall mean the Microelectronics Product Purchase
Agreement between Lucent and Agere effective as of February 1, 2001, and any
other agreement pursuant to which Lucent purchases products or services from
Agere, and reference in this Article V to specific provisions within the
Microelectronics Product Purchase Agreement between Lucent and Agere effective
as of February 1, 2001 shall be deemed to include similar provisions contained
in such other agreements.

      5.2 RESOLUTION PROCESS. In the event of the occurrence of certain events
identified below in Section 5.4 ("Trigger Events") with respect to one or more
Products for which Agere is Lucent's sole source of supply and for which there
is no commercially available substitute (hereinafter "Sourced Product"), Lucent
may notify Agere in writing that (i) a Trigger Event (as defined in Section 5.4
below) has occurred, describing with specificity the facts giving rise to the
Trigger Event, and (ii) Lucent wishes to invoke its rights under this Article V.
After receipt of such notice, Agere shall respond to Lucent within seven (7)
business days with a Plan of Action to address the issues raised in the


                                       18
<PAGE>   26
notice from Lucent. In the event Agere fails to deliver a Plan of Action
reasonably acceptable to Lucent within the seven (7) business day period, or in
the case of an Epidemic Failure Trigger, as defined in Section 5.4.3 below,
Agere fails to cure the defect in the manner and within the cure period set
forth in the Plan of Action, Lucent may exercise its rights under Section 5.3
below, and in addition, invoke all of its rights under the Supply Agreement.

      5.3   MANUFACTURING RIGHTS.

      5.3.1 If pursuant to the Section 5.2 of this Article V, Lucent invokes
this Section 5.3, Lucent may, with respect to a Sourced Product, notify Agere of
Lucent's intention to either manufacture the Sourced Product or have the Sourced
Product manufactured by a third party ("Second Source"). In the event of a
notice of second source manufacture to Agere, Agere may notify Lucent, within
fifteen (15) business days, that it wishes to submit the matter for resolution
by Lucent's senior purchasing executive and Agere's appropriate senior
executive. If the matter is not thus resolved within twenty (20) days, then the
matter may be submitted by either party to an expedited binding arbitration to
take place in New Jersey, with costs to be shared equally, for a determination
of whether the foregoing default has occurred, which is to be completed within
twenty (20) business days. The parties agree that by March 1, 2001, the parties
shall select an arbitrator to adjudicate disputes on a continuing basis under
this clause. Upon failure of the parties to agree on the selection of an
arbitrator by March 1, 2001, the American Arbitration Association shall be
requested to make the selection.

      5.3.2 Upon failure of Agere to submit the matter for resolution by senior
executives or upon the conclusion of an arbitration finding an unresolved
Trigger Event exists with respect to a Sourced Product, then Lucent shall have,
in addition to any rights provided elsewhere in this Agreement, the following
rights with respect to such specific Sourced Product:

      5.3.2.1 a perpetual, personal, nonexclusive, non-transferable,
irrevocable, worldwide, royalty-free right to distribute the Joint Technical
Information and Lucent's derivative works thereof to a Second Source and to
sublicense such Second Source to make and sell such Sourced Product for third
parties, for so long as the Second Source supplies the Sourced Product to Lucent
and for three (3) years thereafter. Lucent shall distribute and sublicense the
Joint Technical Information under confidentiality terms consistent with those
ordinarily used by Lucent in connection with its disclosure of its own
proprietary information, and shall require return or destruction of the Joint
Technical Information when the Second Source ceases to have the right to supply
the Sourced Product; and

      5.3.2.2 a personal, nonexclusive, non-transferable, irrevocable,
worldwide, royalty-free right to sublicense a Second Source under Agere's
Required Patents to make, use and sell the Sourced Product to third parties to
the extent the Second Source uses the Joint Technical Information to manufacture
the Sourced Product, for so long as the Second Source supplies the Sourced
Product to Lucent and for three (3) years thereafter.


                                       19
<PAGE>   27
      5.4  TRIGGER EVENTS.  The following events are deemed "Trigger
Events" for a Sourced Product:

      5.4.1 If Agere should at any time during the term of any Supply Agreement
determine that a Sourced Product is a candidate to be discontinued by Agere, as,
for example, per the terms of the Section 16 of the Supply Agreement, and (1)
Lucent is unable to obtain sufficient quantities of such Sourced Product due
solely to Agere being unable or unwilling to deliver the Sourced Product
requested by Lucent under the Lucent's last time purchase, or (2) following a
last time buy under, for example, the aforementioned Section 16, of Sourced
Product in quantities covering a twelve months' supply of Sourced Product, based
on Lucent's previous year's purchases, Lucent requires additional quantities of
such Sourced Product.

      5.4.2 If (1) Agere should at any time "no bid" a Request for Quotation
(RFQ) from Lucent in connection with a new product , and (2) Lucent receives no
third party responses to such RFQ, and Lucent can demonstrate to Agere that any
third party response to such RFQ will be solely dependent upon Lucent invoking
its rights under Section 5.3. This Trigger Event shall not apply with respect to
Epoxy Formulations listed on Schedule F.

      5.4.3 If an Epidemic Failure (as defined, for example, in Attachment D to
the Supply Agreement) occurs with respect to a Sourced Product and Agere fails
to perform its obligations in accordance with applicable contractual provision,
including, for example, said Attachment D, after written notice from Lucent of
such failure and opportunity to cure within thirty (30) days (an "Epidemic
Failure Trigger").

      5.5 OTHER ACCESS AND COPY RIGHTS WITH RESPECT TO SOLE SOURCED PRODUCTS. In
order to facilitate Lucent use of design information, such as netlists, timing
specifications and test vectors relating to certain products for which Agere is
Lucent's sole source of supply, and with respect to which Lucent has retained
ownership rights under other provisions of this Agreement (hereinafter "Sourced
Product Design Information"), Agere agrees to cooperate with Lucent to (a)
identify products for which Sourced Product Design Information in the possession
of Lucent is incomplete, or for which up to date files containing Lucent Sourced
Product Design Information are in the possession of Agere, (b) define a mutually
agreeable procedure and schedule for access, copy and transfer of such Sourced
Product Design Information to Lucent, and (c) provide Sourced Product Design
Information to Lucent in accordance with said procedure and schedule.

      5.6 ACCESS, COPY AND TRANSFER PROCEDURE AND SCHEDULE. The parties agree to
cooperate with each other to implement a specific and detailed process for
access, copying and transfer of Sourced Product Design Information, in order to
insure that (a) all access and copying will be substantially completed prior to
December 31, 2001, and (b) adequate provision will be made for accommodating any
special cases or eventualities that may arise. The process shall specify target
time periods in which a response to a request for access and copying shall be
transmitted to Lucent, which period shall, unless otherwise agreed, not exceed
ten (10) working days. Lucent shall use good faith efforts


                                       20
<PAGE>   28
to minimize the number and frequency of requests made hereunder, and Agere shall
use good faith efforts to accommodate the business needs of Lucent.

      5.7 CONTENT AND HANDLING OF REQUESTS FOR ACCESS AND COPYING. All requests
from Lucent for access and copying shall clearly identify: (a) the item(s)
requested, (b) the Lucent subject matter expert or accountable associate, (c)
whether a copy or access is requested, (d) if a copy is requested, the desired
delivery interval for the copy, which interval shall be no shorter than the
targeted interval set forth above, (e) if known, the location of the material
being requested (f) if access is requested, the specifics of how the access was
made in the past, and (g) any special handling that is requested (e.g.,
overnight delivery, maximum approved cost). Agere shall promptly acknowledge
receipt of each such request, and expeditiously process such request, so as to
provide the requested Sourced Product Design Information to Lucent in accordance
with the agreed upon schedule. In the event that Agere determines that requested
Sourced Product Design Information is not available, cannot be located, or
cannot be provided as specifically requested, Agere will notify Lucent promptly.

Copies of Sourced Product Design Information will be provided to Lucent in the
original size, content, form and clarity. The latest version of Sourced Product
Design Information will be provided unless otherwise requested.

      5.8 RETENTION. Agere agrees that it will retain both current and previous
versions of all Sourced Product Design Information subject to access and
copying, and that it will not destroy or otherwise dispose of any Sourced
Product Design Information without first notifying Lucent and obtaining written
agreement either to destroy the copy, or to provide the copy to Lucent.

not use any such information other than for the purposes of performing its
obligations under this Agreement, except, in each case, to the extent that such
information has been (i) in the public domain through no fault of such party or
any of their respective directors, officers, employees, agents, accountants,
counsel and other advisors and representatives, (ii) later lawfully acquired
from other sources by such party which sources are not themselves bound by a
confidentiality obligation, or (iii) independently generated without reference
to any proprietary or confidential information of the other party.

      (b) Each party agrees not to release or disclose, or permit to be released
or disclosed, any such information to any other person, except its directors,
officers, employees, agents, accountants, counsel and other advisors and
representatives who need to know such information for purposes of performing
such party's obligations under this Agreement (who shall be advised of their
obligations hereunder with respect to such information), except as specified in
Section 2.5 or in compliance with Section 9.4(d) or with the prior written
consent of the other party.

(c) Without limiting the foregoing, when any information is no longer needed for
the purposes contemplated by this Agreement, each party will promptly after
request of a furnishing party either return to the furnishing party all
information in a tangible form (including all copies thereof and all notes,
extracts or summaries based thereon) or certify to the furnishing party that it
has destroyed such information (and such copies thereof and such notes, extracts
or summaries based thereon).

      (d) In the event that any party (the "disclosing party") either determines
on the advice of its counsel that it is required to disclose any information
pursuant to applicable law or receives any demand under lawful process or from
any governmental authority to disclose or provide information of any other party
that is subject to the confidentiality provisions hereof, such disclosing party
shall notify the other party prior to disclosing or providing such information
and shall cooperate at the expense of the other party in seeking any reasonable
protective arrangements requested by such other party. Subject to the foregoing,
the person that received such request may thereafter disclose or provide
information to the extent required by such law (as so advised by counsel) or by
lawful process or such governmental authority.

      9.5 COUNTERPARTS; ENTIRE AGREEMENT; CORPORATE POWER.  (a)  This
Agreement may be executed in one or more counterparts, all of which shall
be considered one and the same agreement.

      (b) This Agreement and any exhibits, schedules and appendices hereto
contain the entire agreement between the parties with respect to the subject
matter hereof, supersede all previous agreements, negotiations, discussions,
writings, understandings, commitments and conversations with respect to such
subject matter and there are no agreements or understandings 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.

      9.6 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, exclusive of
Conflicts of Laws provisions, as to all matters, including matters of validity,
construction, effect, enforceability, performance and remedies.

      9.7 ASSIGNABILITY; SUCCESSORS. (a) This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and assigns; provided, however, that a party-grantee may not assign this
Agreement, in whole or in part, or its respective rights or obligations without
the prior written consent of the party-grantor except as provided in Section
9.7(b) below.

      (b) By the provision of notice thereof in accordance with this Agreement,
a party may assign this Agreement and its rights and obligations hereunder,
either in whole or in part, to any entity that is, or that was immediately
preceding such assignment, a current Subsidiary, business unit, division or
other Related Company of such party, in each case that is the successor to the
business and assets of any such party that relates to this Agreement.

      (c) If Lucent, Agere or any of their Related Companies, divests a portion
of its business and such divested business continues operation as a separately
identifiable business, then the licenses and rights granted hereunder to the
divesting party may be sublicensed to such divested separate business without
the consent of the other party, but only to the extent and for the time the
divested business functions as a separately identifiable business. With respect
to patent licenses, such sublicenses shall further be limited to products and
services of the kind provided by the divested business prior to its divestiture
and not to any products or services of any entity which acquires the divested
business. With respect to all other intellectual property licenses herein, such
sublicenses shall further be limited to products and services of the kind
provided or under development by the divested business prior to its divestiture
and not to any other category of products or services of any entity which
acquires the divested business. As used herein, the term "other category of
products or services" of an acquiring entity shall mean only those products and
services which are not of the kind or type provided by the divested business
prior to its divestiture. This Section 9.7(c) shall apply regardless of whether
the business is divested by a distribution to existing shareholders, a sale of
assets

                                       28
<PAGE>   36
or as a sale of a legal entity (e.g., sale of a Subsidiary). The sublicensing
rights specified herein shall include any business whose acquisition is after
the Effective Date, provided the acquisition of such business was not a sham for
the purpose of extending rights to the acquired (and then divested) business.

      9.8 THIRD PARTY BENEFICIARIES. 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.

      9.9 NOTICES. All notices or other communications under this Agreement

      9.10 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


                                       29
<PAGE>   37
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.

      9.11 FORCE MAJEURE. Except with respect to payment obligations hereunder,
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.

      9.12 PUBLICITY. Each of Lucent and Agere shall consult with each other
prior to issuing any press releases or otherwise making public statements with
respect to this Agreement or the transactions contemplated hereby. In addition,
neither party shall issue or release for publication any articles, advertising,
or publicity materials relating to Licensed Technology of the other party under
this Agreement or mentioning or implying the name, trademarks, logos, trade
name, service mark or other company identification of the other party or any of
its affiliates or any of its personnel without the prior written consent of the
other party.

      9.13 HEADINGS. The article, section and paragraph headings contained in
this Agreement are for reference purposes only and shall not affect in any way
the meaning or interpretation of this Agreement.

      9.14 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.

      9.15 SPECIFIC PERFORMANCE. 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 specific performance and 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 specific performance 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.

      9.16 AMENDMENTS. No provision of this Agreement shall be deemed waived,
amended, supplemented or modified by any party, unless such waiver, amendment,
supplement or modification is in writing and signed by the authorized
representative of the party against whom it is sought to enforce such waiver,
amendment, supplement or modification.

      9.17 INTERPRETATION. Words in the singular shall be held to include the
plural and vice versa and words of one gender shall be held to include the other
genders as the context requires. The terms "hereof," "herein," and "herewith"
and words of similar import shall, unless otherwise stated, be construed to
refer to this Agreement as a whole (including all of the schedules, exhibits and
appendices hereto) and not to any particular provision of this Agreement.
Article, section, exhibit, schedule and appendix references are to the articles,
sections, exhibits, schedules and appendices to this Agreement unless otherwise
specified. The word "including" and words of similar import when used in this
Agreement shall mean "including, without limitation," unless the context
otherwise requires or unless otherwise specified. The word "or" shall not be
exclusive. Unless expressly stated to the contrary in this Agreement, all
references to "the date hereof," "the date of this Agreement," "hereby" and
"hereupon" and words of similar import shall all be references to the Effective
Date, regardless of any amendment or restatement hereof.
