papers and do all acts (and in the case of Lucent, have Lucent JDC Assignees
sign all papers and do all acts, and in the case of Agere, have Agere JDC
Assignees sign all papers and do all acts) which may be necessary, desirable or
convenient to enable filing and prosecuting of all applications for patents on
inventions arising from work under this Agreement and to enable maintenance of
patents granted thereon. The Parties also agree to acquire from their respective
JDC Assignees who perform work in furtherance of this Agreement, such
assignments, rights and covenants as are necessary to assure that each Party
shall receive any and all licenses and rights it is entitled to acquire
hereunder.

         (c) Assignment of Interest. Notwithstanding each Party's undivided
one-half (1/2) ownership interest in Joint Patents, during the Term of this
Agreement a Party shall not assign its entire interest, or any portion thereof,
in any Joint Patent to any third party (other than to a Party's Subsidiaries)
without the express written consent of the other Party. If any attempt is made
by one Party to assign its interest in any Joint Patent without the other
Party's consent, all of the one Party's interest in that Joint Patent which such
one Party attempts to assign shall automatically be extinguished, and the other
Party shall have sole ownership in that Joint Patent subject to the one Party
retaining the rights under such Joint Patent as set forth in Section 4.6(d).

         (d) Rights of each Party under Joint Patents. Lucent and Agere shall
each have, under Joint Patents, the rights to make, have made, use, lease, offer
to sell, sell and import any products and services of their respective
businesses in which they are now or hereafter engaged. Such rights shall also
extend to Subsidiaries of Lucent and Agere.

         (e) Patent prosecution and maintenance of Joint Patents. (i) The
Parties agree that all patent prosecution and maintenance decisions, both in the
United States and in foreign counties, shall be made jointly by the Parties,
after consultation. All expenses for prosecuting each Joint Patent and for issue
and maintenance of each Joint Patent shall be equally borne by the Parties. As
mutually agreed by the Parties, one Party shall retain primary responsibility
for prosecuting each patent application which is a Joint Patent hereunder. At a
Party's request, the other Party shall furnish any assistance that may be
necessary during the prosecution of such patent application.

              (ii) In the case of a Joint Patent which is filed in a country
which requires the payment of taxes or annuities on a pending patent application
or on an issued patent, the Parties shall equally share in the payment of such
taxes and annuities for all Joint Patents.

                                      -10-
<PAGE>   14
              (iii) The responsible prosecuting Party (pursuant to Section
4.6(e)(i) above) will pay all prosecution expenses, taxes and annuities
associated with any Joint Patent, and within sixty (60) days from receiving
evidence of such payment, the other Party will reimburse such responsible Party
for fifty percent (50%) of such expenses, taxes and annuities.

              (iv) Neither Party will be required, however, to incur any costs,
such as patent application costs, to which it has not agreed. If, after the
Parties meet and discuss matters relating to obtaining patent protection for
Joint Inventions, one Party does not want to pursue filing a patent application
on any Joint Inventions in any country, the other Party may independently pursue
patent protection of such Joint Invention in such country on behalf of that
Party only at that Party's sole expense. The Party who so pursues patent
protection in such country will be the sole owner of any resulting issued patent
in such country and will be entitled to all revenues derived by such Party
relating to the resulting issued patent, provided, however, that the other Party
will have a worldwide, perpetual, nontransferable, nonexclusive, royalty-free
license to make, have made, use, sell, offer to sell, import or lease products
or services of such other Party's businesses. In the event that one Party elects
not to continue prosecution of any pending patent application which is a Joint
Patent, or not to pay any tax or annuity due on a Joint Patent, such one Party
will offer to the other Party (and will effect an assignment if such offer is
accepted) a fee-free assignment of the one Party's one-half (1/2) interest in
such application or Joint Patent, subject to the transferring Party retaining a
non-exclusive, irrevocable, and fully transferable license under such
application or Joint Patent to make, have made, use, lease, offer to sell, sell,
and import any or all products and services of any type or kind.

              (v) Neither Party may, without the express written consent of the
other Party, disclaim or dedicate any Joint Patent, or file for reissue or
reexamination, or undertake any other procedure or perform any act which may
affect the scope or validity of any of the Joint Patents, other than as required
in the course of normal prosecution under 4.6(e). The foregoing limitation on
filing for reissue or reexamination shall not, however, apply in the event that
one Party has instituted litigation with respect to one or more Joint Patents,
and the other Party has no litigation pending with respect to such one or more
Joint Patents.

         (f) Licensing of Joint Patents to Third Parties. (i) Each Party shall
have the right to grant nonexclusive, personal, non-assignable licenses under
Joint Patents to any third party anywhere in the world. Each Party hereby
consents to the grant of such licenses by the other Party, and gives such
consent to the extent that such consent is necessary to effectuate the licenses
granted, and consents to the retaining by the licensing Party of all revenues,
royalties and benefits received for such licenses without accounting therefor to
the non-licensing Party.

         (g) Enforcement of Joint Patents. (i) Subject to the provisions of this
Section, each Party shall have the right to bring any litigation against any
third party under any Joint Patent, without the consent of the other Party. The
other Party hereby consents to be joined as a party to the litigation, if
required.

              (ii) Each Party shall notify the other, in writing, at least
thirty (30) days prior to institution of any litigation involving one or more
Joint Patents. The Parties agree to negotiate

                                      -11-
<PAGE>   15
with each other, in good faith, in the event that either Party determines that
the institution of litigation is not in its best interests, and that there is a
preferable alternative available that would satisfy the interests of both
Parties. Following the giving of such notice, the Party receiving the notice
shall not (A) for the initial period of three (3) months following such
notification, and (B) during the course of the litigation and until its
conclusion by settlement or execution of judgment, license or attempt to license
any such Joint Patent to the third party identified in the notice or the third
party that is the subject of the litigation.

              (iii) Unless otherwise agreed by the Parties, the Party initiating
any litigation involving any Joint Patent (A) shall promptly notify the other
Party of the initiation of such litigation, (B) shall have sole control of the
litigation, (C) shall incur all expenses and costs (including reasonable
expenses associated with requested participation of the joined other Party as
co-owner), and (D) shall retain any and all amounts recovered as a result of
such litigation without accounting therefor to the other Party.

              (iv) Each Party shall promptly notify the other Party in the event
that any third party asserts by lawsuit, license discussions or otherwise any
invalidity claims as to any Joint Patent.

         4.7 Covenant Not to License.

         (a) Unless otherwise provided in this Agreement (e.g., Section
6.2(c)(ii)), or a Project Letter, or mutually agreed upon in writing, during the
Term of this Agreement and for a period of six (6) months after the expiration
of or any termination of this Agreement, Agere shall not have any right to
license, and will not license, the Joint Information, Foreground Technology,
MEMS Technical Information and/or the results from a JDC Deliverable to any
Lucent Competitor, provided, however, that Agere shall not be precluded from
manufacturing (or having made for Agere's own use and resale) and selling Agere
products or services which include Joint Information, Joint Patents, Foreground
Technology, MEMS Technical Information and/or the results from a JDC
Deliverable.

         (b) Unless otherwise provided in this Agreement (e.g., Section
6.2(c)(ii)), or a Project Letter or mutually agreed upon in writing, during the
Term of this Agreement, Lucent shall not have any right to license, and will not
license, the Joint Information, Foreground Technology, MEMS Technical
Information and/or the results from a JDC Deliverable to any Agere Competitor,
provided, however, that Lucent shall not be precluded from manufacturing and
selling Lucent products or services which include Joint Information, Foreground
Technology, MEMS Technical Information and/or the results from a JDC Deliverable
or having such products or services made (or having any components or subsystems
made for use in such products or services) by any third party or having such
products or services made (or having any components or subsystems made for use
in such products or services) in the event of a Supply Failure (subject to the
terms of the Agere Supply Agreement). In addition, for a period of six (6)
months following the expiration or termination of this Agreement, Lucent shall
be restricted from licensing an Agere Competitor under such Joint Information,
Foreground Technology, MEMS Technical Information and/or the results from a JDC
Deliverable except to have a MEMS Product developed and/or manufactured by any
third party where for a period of six (6)

                                      -12-
<PAGE>   16
months, as measured from the relevant third party's equivalent of General
Availability as defined hereunder, such third party shall be restricted to
supplying only Lucent with the relevant MEMS Product but only for such six month
period.

         4.8 Sublicenses to Subsidiaries.

The grant of each license hereunder includes the right to grant sublicenses
within the scope of such license (but not the right to grant further
sublicenses) to a Party's Subsidiaries for so long as they remain its
Subsidiaries. Any and all licenses or sublicenses granted to Subsidiaries
pursuant to this Agreement may be made effective retroactively, but not prior to
the Effective Date hereof, nor prior to the sublicensee's becoming a Subsidiary
of such Party.




               ARTICLE 5.0 - JDC OPTICAL MEMS TECHNOLOGY PLATFORM

         5.1 One focus of the JDC is the joint research and advancement of the
Optical MEMS Technology Platform (hereinafter, for convenience, "the Technology
Platform").

         5.2 Overall Technology Plan. All joint activities undertaken by the JDC
will be in accordance with the approved Technology Platform jointly developed
and agreed to by the Parties. An overall technical plan ("Overall Technical
Plan") consistent with the Technology Platform for the JDC will be prepared by
the Technical Board. Such Overall Technical Plan will be prepared, presented to
and agreed to by the Executive Board within thirty (30) days after the Effective
Date of this Agreement. All changes to the Technology Platform and Overall
Technical Plan shall be approved by the Executive Board.

         5.3 Periodic Reviews. The Technical Board will meet at least on a
quarterly basis to discuss potential and existing Work Projects and JDC
Deliverables directed to the Technology Platform and modifications to the
Overall Technical Plan or Technology Platform. Written proposals for Work
Projects consistent with the Overall Technical Plan will be submitted by the JDC
Assignees to the Technical Board for approval. Such proposals shall be submitted
for potential Work Projects to the Technical Board thirty (30) days in advance
of any scheduled Technical Board meeting. Such written proposals shall (a)
provide a description of the work to be performed in sufficient detail to
determine whether to establish a Work Project; (b) provide a detailed budget
required to complete the Work Project including staffing requirements,
equipment, overhead allocations and the like; (c) identify a lead JDC Assignee
for the Work Project; (d) specify a time period of performance together with a
preliminary set of identified JDC Deliverables and completion date; and (e) any
other information deemed relevant by the submitter of such proposal for approval
purposes.

         5.4 Joint Information. The Parties agree that any technical

<PAGE>   17
Deliverables or any other output of the JDC directed to the Technology Platform
in accordance with this Article 5.0 shall be Joint Information.


                ARTICLE 6.0 - PRODUCT DEVELOPMENT AND MANAGEMENT

         6.1 In addition to the Technology Platform activities hereunder,
another focus of the JDC is the joint development of optical MEMS Products.

         6.2 MEMS Product Development Decision Process.

         (a) All development of optical MEMS Products under the JDC shall be
approved by the Executive Board in accordance with this Section.

         (b) Written proposals for Work Projects directed to the development of
a particular optical MEMS Product may be submitted jointly by the Parties or
individually by a Party. In recognition of the critical resources required to
effectively operate the JDC, each Party agrees to keep such individual Party
submissions to a minimum level per calendar year. All such proposals for
potential Work Projects shall be submitted to the Executive Board thirty (30)
days in advance of any scheduled Executive Board meeting or at such other
mutually agreeable times. Such written proposals shall (a) provide a description
of the optical MEMS Product and work to be performed in sufficient detail to
determine whether to establish a Work Project; (b) provide a detailed budget
required to complete the Work Project including staffing requirements,
equipment, overhead allocations and the like; (c) identify a lead JDC Assignee
for the Work Project; (d) specify a time period of performance together with a
preliminary set of identified JDC Deliverables and completion date; and (e) any
other information deemed relevant by the submitter of such proposal for approval
purposes.

         (c) (i) The Executive Board shall review each optical MEMS Product
development submission and determine whether joint development between the
Parties of the particular optical MEMS Product is desirable. If joint
development is approved in writing by the Executive Board, a separate Project
Letter shall be agreed to in writing by the Parties with respect to the
particular joint development in accordance with Section 6.3 below. If a Project
Letter is not executed by the Parties within ninety (90) days (or any extensions
thereto as mutually agreed by the Parties) of the date of the Executive Board's
written approval, each Party is free to pursue independent development of the
relevant MEMS Product outside of the JDC in accordance with Section 6.2(c)(ii),
as appropriate. After execution of the Project Letter between the Parties, the
particular optical MEMS Product shall be deemed a Joint MEMS Product in
accordance with the terms of this Agreement.

         (ii) If joint development is not approved, the Party interested in
pursuing the development of the particular optical MEMS Product may do so on an
independent basis outside the constructs of the JDC provided that such activity
does not materially adversely impact such Party's JDC Assignees ability to
execute on JDC activities. Any intellectual property created under such Party
independent development shall vest solely in such Party. Independent product


                                      -14-
<PAGE>   18
development by Lucent and Agere in accordance with this Section shall be subject
to the following:


                  (A) With respect to any independent product development
                  undertaken by a Party hereunder, such Party shall be free to
                  develop and manufacture such optical MEMS Product for itself
                  or develop such optical MEMS Product with any third party and
                  have such optical MEMS Product manufactured by a third party
                  and exercise all rights and licenses, including the granting
                  of licenses and/or sublicenses to any third parties consistent
                  with this Agreement, hereunder to the extent necessary for
                  such Party to develop and manufacture or have such optical
                  MEMS Product developed and manufactured by any third party. In
                  the event such Party elects to develop the optical MEMS
                  Product with a third party and has granted licenses and/or
                  sublicenses to any third party to enable such development and
                  manufacture, such Party agrees that for a period of six (6)
                  months (or some other period as mutually agreed to by the
                  Parties), as measured from the relevant third party's
                  equivalent of General Availability as defined hereunder, such
                  third party shall be restricted to supplying only such Party
                  with the relevant optical MEMS Product. After the expiration
                  of such time period of exclusive supply to such Party, the
                  third party may be fully licensed, at such Party's discretion,
                  in accordance with the rights and licenses hereunder to make
                  and sell the particular optical MEMS Product (including any
                  derivative or improvement thereof) on the commercial market to
                  any and all customers.

                  (B) Notwithstanding the foregoing, with respect to independent
                  product development undertaken by Lucent under this Section
                  6.2(c)(ii), in no event shall any third party engaged by
                  Lucent under Section 6.2(c)(ii) have access to the SFRL during
                  the Term of this Agreement with respect to such development
                  activity between Lucent and such third party unless previously
                  approved by Agere.

         (d) Notwithstanding the above approval process, the Parties agree to
continue or enter into good faith negotiations after the Effective Date with
respect to specific Project Letters as set forth in Appendix J hereto.


         6.3 Project Letters.

         (a) In accordance with this Agreement, Lucent and Agere presently
contemplate the future execution by them of one or more written Project Letters
directed to the development of Joint MEMS Products. All transactions between
Lucent and Agere which relate to a Project Letter shall be covered by such
Project Letter and the terms of this Agreement.

                                      -15-
<PAGE>   19
         (b) Each duly executed Project Letter shall be deemed, upon its
execution, to include the terms of this Agreement. If the Project Letter
conflicts with the terms and conditions of this agreement, the terms and
conditions of the Project Letter shall control.

         (c) Lucent and Agere agree that each Project Letter, at a minimum,
shall specify the information outlined below:

                    endpoint specifications for all Joint MEMS Products
                    detailing performance, quality and other material criteria
                    related thereto (collectively "End Point Specifications").
                    Such Endpoint Specifications shall be mutually agreed upon
                    and thereafter be used with respect to delivering and
                    acceptance of Joint MEMS Products in accordance with the

                    and/or Technical Board.


                 ARTICLE 7.0 - STRUCTURE AND STAFFING OF THE JDC

         7.1 The JDC will be operated for the mutual benefit of Lucent and
Agere. The JDC will focus primarily on optical MEMS development activities in
accordance with this Agreement. Notwithstanding the foregoing, the Parties
recognize that the SFRL has other non-MEMS capabilities and may be used by Agere
for such non-MEMS related work on a reasonable basis, such basis not to
materially adversely impact the objectives of the JDC or performance of the
Parties hereunder.

         7.2 JDC Assignees.

                                      -17-
<PAGE>   21
         (i) Unless otherwise agreed by the Parties and compensated accordingly,
Lucent and Agere will assign personnel to the JDC in overall comparable numbers
to the headcount levels as set forth in Appendix F and Appendix G, respectively.
Lucent shall make reasonable efforts to have the Lucent personnel identified in
Appendix F assigned as JDC Assignees but in no way guarantees the participation
of any of such identified (or any other) personnel in the JDC. Agere shall make
reasonable efforts to have the Agere personnel identified in Appendix G assigned
as JDC Assignees but in no way guarantees the participation of any of such
identified (or any other) personnel in the JDC. Failure by either Party to have
any specific employees assigned to the JDC shall not be considered a breach of
this Agreement in any way whatsoever.

         (ii) The Parties recognize that the full (i.e., 100%) dedication of any
one JDC Assignee may not be possible, required, or in the best interest of such
JDC Assignee. As such, no JDC Assignee shall be required to work solely on JDC
activities but the individual JDC Assignee will use reasonable efforts to ensure
that JDC activities are not materially adversely impacted by participation in
other activities. The Parties agree to attempt to minimize the overall turnover
in the number of personnel each designates for assignment as JDC Assignees and
shall keep accurate records of the respective JDC Assignees of each Party during
the Term of this Agreement.

         7.3 No JDC Employees. Any employees assigned to the JDC will be solely
the employee of his or her assigning Party, and the other Party will not be
considered to be a joint employer of such employee. There will be no employees
of the JDC because it is not a separate legal entity.

         7.4 Wages and Benefits. Wages and benefits for each JDC Assignee will
be provided by the Party employing such JDC Assignee.

         7.5 JDC Assignee Changes. Each Party will review with the other Party,
in advance, personnel changes, reassignments, or relocation applicable to the
JDC. It is anticipated by both Parties that certain key JDC Assignees will serve
for the initial term of the Agreement, unless the individual JDC Assignee opts
to unilaterally terminate his or her assignment to the JDC. The Parties expect
that personnel assignments to the JDC by the Parties will be for the initial
Term of this Agreement, but with the understanding that either Party will have
the option to provide for natural opportunities for shifting people out of the
JDC and back to other positions or growth positions. Criteria will be
established by the Executive Board for the termination of assignments of
personnel to the JDC based on non-performance.

         7.6 Special Compensation Plan. If desirable, and mutually approved by
the Parties, the Parties agree to establish the Special Compensation Plan. This
optional compensation plan will include an opportunity for JDC Assignees to
receive an additional bonus to be paid by the JDC Assignee's employer, over and
above any bonus or other compensation paid by the JDC Assignee's employer in
accordance with such employer's standard employee compensation plan, in the
event the JDC meets or exceeds its objectives, as determined and agreed to by
the Parties on an annual basis while this Agreement is in effect. If so
established, each JDC Assignee will participate in the Special Compensation
Plan. The Special Compensation Plan will be structured to incent the personnel
of the JDC to provide JDC Deliverables and/or MEMS Products at a

                                      -18-
<PAGE>   22
superior cost, quality, and schedule. The funding of the Special Compensation
Plan shall be mutually agreed to in writing by the Parties at the time of the
Plan's establishment. The Executive Board shall be responsible for
administration and approving all distributions of funds to JDC Assignees in
accordance with the Special Compensation Plan.


                       ARTICLE 8.0 - GOVERNANCE OF THE JDC

         8.1 Executive Board Governs. The JDC will be governed by the Executive

($250,000) individually or in the aggregate.

             (iii) Adoption and amendment of personnel policies, manuals and the
Special Compensation Plan for JDC Assignees.

             (iv) Selection of locations for the JDC's operations or expansion,
relocation or significant reduction of any JDC facility including the SFRL.

             (v) Any significant action or transaction not in the ordinary

         8.2 Executive Board Meetings. Meetings of the Executive Board will be
held monthly for the first year of this Agreement and thereafter as mutually
agreed. The Executive Board meetings may be conducted on either a face-to-face
basis or via video or telephone conference call, whichever is mutually agreed to
by the Parties at least ten (10) business days in advance of the scheduled
meeting. Special meetings may be called by any two members of the Executive
Board, one (1) from each Party, upon at least (i) ten (10) business days prior
notice for a face-to-face meeting or (ii) seventy-two (72) hours prior notice
for a telephonic or video conference meeting. The Executive Board may also act
without a meeting upon the unanimous written consent of all the Board members.

         8.3 Quorum and Majority Vote. A quorum of the Executive Board will
consist of at least four (4) members, including at least two (2)

<PAGE>   23
members representing Agere and at least two (2) members representing Lucent. No
action may be taken at any meeting of the Executive Board in the absence of a
quorum. All actions of Executive Board and/or Technical Board shall require a
majority agreement. All actions and approvals will be reduced to writing and
distributed to the Parties.

         8.4 In the event all of the members representing one of the Parties
fail to attend a meeting duly noticed and called, the members in attendance at
the next duly noticed and called meeting, which may be a special meeting called
as provided in Section 8.2, may take action regardless of whether a quorum is
present.

         8.5 Deadlock. All deadlocks of the Executive Board and/or Technical
Board with respect to any issue, act, approval or other action necessary
hereunder shall be resolved in accordance with Article 22.0.


                  ARTICLE 9.0 - JDC OPERATIONS, LOCATION & SFRL

         9.1 JDC Location. As of the Effective Date, the JDC will be physically
located initially at a site in the Murray Hill, New Jersey area. The Parties may

directed by the Technical Board as supported by the Executive Board.

         9.3 Common Services. Except for the provision of Landlord Services
(under and as defined in the Lease Agreement) with respect to which Agere shall
pay additional rent to Lucent as required therein, Lucent and Agere will work
together to define the most efficient ways to provide common support services to
the JDC at mutually agreed to costs. Common support services will be benchmarked
periodically against competitors and industry benchmarks to determine their
current competitiveness and will be reviewed with the Executive Board. Common
support services that are available from outside sources at competitive prices
may be obtained from such sources unless precluded by written policies of either
Party. Common support services that are not available from outside sources will
be included as a common expense and all expenses of the JDC are to be shared
between the Parties unless otherwise agreed to in writing (subject to the terms
of the Lease Agreement).

         9.4 Facilities. The Parties, by mutual agreement and in accordance with
the Lease Agreement, will utilize the building, facilities, and infrastructure
and will manage the operations which support the JDC with sufficient capacity to
meet the objectives of the JDC. Each Party shall provide these assets as part of
that Party's financial commitments to the JDC as determined in Section 4.1.
Notwithstanding the foregoing, pursuant to the Lease Agreement, Lucent shall
retain any and all management control over the space leased under the Lease
Agreement.

         9.5 SFRL Location and Equipment Purchase Option.

                                      -20-
<PAGE>   24
         (i) Unless otherwise mutually agreed by the Parties and subject to the
Lease Agreement, the SFRL shall remain at its current location in Murray Hill,
New Jersey and Agere shall be responsible for the day-to-day operation and
staffing of the SFRL. Each Party shall have equal access to the SFRL for
carrying out the JDC activities hereunder.

         (ii) In the event Agere desires to remove a particular piece of MEMS
Equipment during the Term of this Agreement or upon expiration of this Agreement
or upon Agere's abandonment of the SFRL, Agere shall provide Lucent with written
notice of Agere's intent on removing such MEMS Equipment, such notice to be
provided three (3) months in advance of removal, and Lucent shall have an option
to purchase such MEMS Equipment prior to removal from SFRL at a purchase price
to be determined by Agere. Such purchase price to be determined taking into
account factors including, but not limited to, replacement costs, removal costs
and/or installation costs. If Lucent exercises the option to purchase the MEMS
Equipment, Lucent shall remit payment to Agere within a period to be mutually
agreed upon between the Parties.

         9.6 Lucent-Owned Flip Chip Bonder

         Lucent agrees that Agere shall have access to a certain Lucent-owned
flip-chip bonder apparatus, i.e., M8 alignment system from RD Automation,
currently located in Lucent's Murray Hill facility but external to the SFRL,
solely with respect to performance of the joint activities of the Parties under
Section 5.0 and Section 6.0 of this Agreement. In addition, Lucent expects to
install a M10 alignment system from RD Automation as a replacement to the
existing M8 alignment system in calendar 2001. If so replaced, Agere shall have
access to the M10 alignment system solely with respect to performance of the
joint activities of the Parties under Section 5.0 and Section 6.0 of this
Agreement. Access, under this Section, to this Lucent flip-chip bonder apparatus
shall be considered as part of Lucent's financial commitments to the JDC as
determined in Section 4.1. Notwithstanding the foregoing, the Parties recognize
that such apparatus has other non-JDC capabilities and may be used by Lucent for
such non-JDC related work on a reasonable basis, such basis not to materially
adversely impact the objectives of the JDC or performance of the Parties
hereunder.

         9.7 The Parties agree that any inconsistencies or conflicts arising
between the Lease Agreement and this Agreement with respect to the leased space
under the Lease Agreement, the payment of rent and additional rent, or
facilities issues associated with the JDC and/or the SFRL are to be resolved in
favor of the Lease Agreement.

from a third party without any obligations regarding confidentiality; or (e)
which is independently developed by the receiving Party; or (f) which is
requested pursuant to a judicial or governmental request, requirement or order
under law, provided that the receiving Party

                                      -22-
<PAGE>   26
provides the disclosing Party with sufficient prior notice in order to contest
such request, requirement or order or seek protective measures.

         (b) that the receiving Party will not, without the disclosing Party's
express written permission, make or have made, or permit to be made, more copies
of any of the furnished Lucent Information or Agere Information than are
necessary for its use hereunder, or associated with subsequent design,
manufacturing or marketing efforts contemplated hereunder, and that each such
copy shall contain the same proprietary notices or legends which appear on the
furnished Lucent Information or Agere Information being copied;

         (c) that all Lucent Information will remain the property of Lucent, and
upon termination of this Agreement, Agere will, at Lucent's written request,

product or service was sold or transferred prior to such termination. In
addition, in the event of a termination for material breach, the rights and
licenses granted to the non-breaching Party hereunder shall survive and continue
after any termination of this Agreement. Except for termination for material
breach, the Parties shall retain all rights and licenses hereunder in the event
of any termination of this Agreement.

confidential information by the Parties, and neither Party shall disclose such
terms to any third party without the prior written consent of the other Party;
provided however, that each Party may represent to third parties that such Party

                   ARTICLE 21.0 - MISCELLANEOUS PROVISIONS

21.1 Integration. The terms and conditions contained in this Agreement and its
attachments supersede all prior oral or written understandings between the
Parties and together with the Intellectual Property Agreements, Project Letters,
the Overall Operations Plan, and the Overall Technical Plan, and any subsequent
plans approved by the Executive Board, will constitute the entire Agreement
between the Parties with respect to the subject matter of this Agreement.
Neither of the Parties will be bound by any warranties, understandings or
representations with respect to the subject matter hereof other than as
expressly provided herein. This Agreement will not be modified or amended except
by a writing signed by Lucent and Agere.

21.2  Nonassignability.

(a) The Parties hereto have entered into this Agreement in contemplation of
personal performance, each by the other, and intend that the rights granted
hereunder to a Party and such Party' obligations not be extended to entities
other than such Party's Subsidiaries without the other Party's express prior
written consent.

(b) Notwithstanding the foregoing, each Party's rights, title, interest and
obligations under this Agreement, and any rights granted to each Party hereunder
may be assigned only to any direct or indirect successor to the business of such
Party as the result of any internal reorganization, which successor shall
thereafter be deemed substituted for such Party as the Party hereof, effective
upon such assignment; but neither this Agreement nor any rights or obligations
hereunder shall be otherwise assignable or transferable (in insolvency
proceedings or otherwise) by either Party without the express written consent of
the other Party.

(c) Notwithstanding the foregoing, either Party may assign all or part of its
rights and obligations to any successor in interest of all or substantially all
of the assets of its business.

21.3 Force Majeure. Neither Party shall be liable for delays in delivery or
performance when caused by any of the following which are beyond the actual
control of the delayed Party: (i) acts of God, (ii) acts of the public enemy,
(iii) acts or failure to act by the other Party, (iv) acts of civil or military
authority, (v) governmental priorities, strikes or other labor disturbances,
(vi) hurricanes, (vii) earthquakes, (viii) fires, (ix) floods, (x) epidemics,
(xi) embargoes, (xii) war, (xiii) riots, (xiv) delays in transportation, and
(xv) loss or damage to goods in transit.


                                      -30-
<PAGE>   34


21.4 Choice of Law. The Parties hereto desire and agree that the laws of the
State of New York, exclusive of its conflict of laws provisions, will apply in
any dispute or controversy arising with respect to this Agreement.

21.5 Headings. All section headings, including those in the Appendices, are for
convenience purposes only and will in no way affect, or be used, in
interpretation of this Agreement.

21.6 Waiver. No failure, delay, relaxation or indulgence on the part of either
Party in exercising any power or right conferred upon such Party under the terms
of this Agreement will operate as a waiver of such power or right nor will any
single or partial exercise of any such power or right preclude any other or
further exercise thereof or the exercise of any other power or right under this
Agreement.

21.7 Releases Void. Neither Party shall require waivers or releases of any
personal rights from representatives of the other in connection with visits to
its premises and both Parties agree that no such releases or waivers shall be
pleaded by them or third persons in any action or proceeding.

21.8 Power To Sign. Agere and Lucent warrant that their respective
representatives signing this Agreement have full power and proper authority to
sign this Agreement and so bind the Parties.

21.9 Severability. If any term, clause, or provision of this Agreement shall be
judged to be invalid, the validity of any other term, clause, or provision will
not be affected; and such invalid term, clause, or provision will be deemed
deleted from this Agreement.

21.10 Auditor. In the event the Parties should have need for the services of any
auditors to monitor or assess the financial activities of the JDC, then the
current auditors for each Party hereto will mutually agree upon the selection of
an auditor to audit the financial activities of the JDC.


                        ARTICLE 22.0 - DISPUTE RESOLUTION

22.1 It is the intent of the Parties to use their respective reasonable best
efforts to resolve expeditiously any dispute, controversy or claim between or
among them with respect to the matters covered hereby that may arise from time
to time on a mutually acceptable negotiated basis. In furtherance of the
foregoing, in the event of a dispute between the Parties, or individual members
of the Executive Board or Technical Board, or on any matter requiring the mutual
approval of their respective Executive Board members or each other, the issue
first will be escalated to the complete Executive Board for attempted resolution
within a reasonable period of time.

22.2 Either Party may initiate dispute resolution by notice to the other Party.
Such notice will be without prejudice to the invoking Party's rights to any
other remedy permitted hereunder.

                                      -31-
<PAGE>   35

The Parties will use commercially reasonable efforts to arrange meetings or
telephone conferences, as needed, at mutually convenient times and places, to
facilitate negotiations between the Parties.

22.3 In the event that the Parties fail or are unable to resolve a dispute
between them after exhausting the resolution process of Section 22.1, the
Parties agree to attempt to further resolve the dispute pursuant to the
escalation provision set forth in Section 22.4 below.

22.4 (a) In furtherance of the foregoing, after exhausting the provisions of
Sections 22.1-22.3, any Party involved in a dispute, controversy or claim
hereunder 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 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 the Parties 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.

22.5  Court Actions

(a) In the event that any Party, after complying with the provisions set forth
in Sections 22.1-22.4 above, desires to commence an Action (as such term is
defined in the Separation and Distribution Agreement), such Party may submit the
dispute, controversy or claim (or such series of related disputes, controversies
or claims) to any 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 and each Ancillary
Agreement (as such term is defined in the Separation and Distribution 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
claim.
